Train operator to stop conductors from clipping tickets so that they don't hurt their wrists

by arbroath (noreply@blogger.com)
mkalus shared this story from Nothing To Do With Arbroath.

A local train operator says it is stopping staff from clipping tickets for fear that it's hurting their wrists.



Abellio Greater Anglia has decided to take the step in order to protect train conductors who can see as many as 600 passengers on a single journey.



From now on, conductors will us other techniques such as putting a red cross on tickets with marker pens. Greater Anglia said that they were reacting to requests from staff. 



A Greater Anglia spokesperson said: "In response to requests from our front line colleagues, we are phasing out the use of clippers and will be using alternative methods of marking checked tickets."

Clone a Raspberry Pi To A Smaller SD-Card And Make Incremental Backups

by Martin

A few days ago the Raspberry Pi Foundation announced a couple of cool new features for their desktop UI, one of them being the ability to clone a running Raspberry Pi system to a smaller SD card. The only condition for using a smaller SD-card is that it is big enough to hold all files stored on the original one. In other words only files are copied and empty blocks are never touched. Intrigued I did some background research on how this works as I see a couple of usage scenarios for me if I can replicate this from the command line.

I’m not sure which code they are using but I found this “rpi-clone” shell script on Github by “billw2” that does exactly what I want. It achieves this by only cloning the 50 MB boot partition block by block with the “dd” command while using the rsync file synchronization command for the system partition which occupies the rest of the SD-card. The script can also be used to incrementally copy only files to the backup SD-card that have changed since the last backup. Once rpi-clone is done the backup SD-card is ready to run. Perfect!

365 days

by Volker Weber

ZZ4891A4B6 ZZ3F27F2DE

Without a goal you cannot score. One year ago I started wearing the Apple Watch and I challenged myself to reach my exercise goals every single day. 600 cals Move, 30 minutes Exercise, 12 hours Stand.

Today I scored. 365 days reaching my move goal, and a longest streak of reaching that goal of the same 365 days. I did not break the chain. Not when I broke three fingers on my right hand, not when I had an infection, not when I had blisters, not a single day.

I did not start a year ago. It was 25 months ago that I set out to solve this problem:

At first I looked at daily steps. I challenged myself to reach 7 million steps in a year. Why 7? I wanted to double the 3.5 million that @MicSpehr scored the prior year. And in contrast to me, he is a sporty guy. I was a couch potato.

Then I looked at the bigger picture. I still don't do sports. But I avoid being lazy. I don't have an e-bike, I don't have a Roomba, I clean the floor every day, I go shopping every single day, to the other end of town. When I am lazy I don't walk. I take the bicycle instead. In those 25 months I have walked about five times the distance I have driven my car and my scooter. Combined.

Once you formed the habit, you don't really need a tracker. That is why fitness bands quickly end up in a drawer. You know what you are doing - or not doing. But they keep a score. And without a score, how can you reach your goal?

Apple Watch has proven to be my perfect tracker. I still wear it every single day, for its notifications, for answering phone calls, for telling the time. And for keeping me from breaking the chain. I reached my 7 million steps goal last year and my 365 days move goal this year. What now? Easy: #dontbreakthechain

If you haven't decided yet: a year from now you will wish you started today. If I can do it, you can do it.

Sunday update: 52 perfect weeks with all three goals

What is the Role of Mozilla’s Executive Chair?

by Jane Finette

What does the Executive Chair do at Mozilla? This question comes up frequently in conversations with people inside and outside of Mozilla. I want to answer that question and clearly define my role at Mozilla. The role of Executive Chair is unique and entails many different responsibilities. In particular at Mozilla, the Executive Chair is something more than the well understood role of “Chairman of the Board.” Because Mozilla is a very different sort of organization, the role of Executive Chair can be highly customized and personal. It is not generally an operational role although I may initiate and oversee some programs and initiatives.   

In this post I’ll outline the major areas I’m focused on. In subsequent posts I’ll go into more detail.

#1. Chair the Board

This portion of my role is similar to the more traditional Chair role. At Mozilla in this capacity I work on mission focus, governance, development and operation of the Board and the selection, support and evaluation of the most senior executives. In our case these are Mark Surman, Executive Director of Mozilla Foundation and Chris Beard, CEO of Mozilla Corporation. Less traditionally, this portion of my role  includes an ongoing activity I call “weaving all aspects of Mozilla into a whole.”  Mozilla is an organizationally complex mixture of communities, legal entities and programs.  Unifying this into “one Mozilla” is important.

#2. Represent Mozilla and our mission to Mozillians and the world

This is our version of the general “public spokesperson” role. In this part of my role, I speak at conferences, events and to the media to communicate Mozilla’s message. The goal of this portion of my role is to grow our influence and educate the world on issues that are important to us. This role is particularly important as we transform the company and the products we create, and as we refocus on entirely new challenges to the Open Web, interoperability, privacy and security.

#3. Reform the ways in which Mozilla values are reflected in our culture, management and leadership

This is the core of the work that is intensely customized for Mozilla. It is an area where Mozilla looks to me for leadership, and for which I have a unique vision. Mozilla’s core DNA is a mix of the open source/free software movement and the open architecture of the Internet. We were born as a radically open, radically participatory organization, unbound to traditional corporate structure. We played a role in bringing the “open” movement into mainstream consciousness. How does and how can this DNA manifest itself today? How do we better integrate this DNA into our current size?  Needless to say I work hand-in-hand with Chris Beard and Mark Surman in these areas.

#4. Strategically advise Mozilla’s technology and product direction

I’ve played this role for just over 20 years now, working closely with Mozilla’s technologists, individual contributors and leadership. I help us take new directions that might be difficult to chart. And in this role I can take risks that may make us uncomfortable in the shorter term but yield us great value over the longer term. By helping to point us towards the cutting edge of our technology, I reinforce the importance of change and adaptation in how we express our values.

#5. Help Mozilla ideas expand into new contexts

I’ve been working with Mark Surman on this topic since he joined us. We’ve expanded our mission and programs into digital literacy and education, journalism, science, women and technology and now the Mozilla Leadership Network. I have also championed Mozilla’s expanded efforts in public policy. I continue to look at how we can do more (and am always open to suggestions).

So these are the different parts of my role. Hopefully it provides you with a framework for understanding what I do and how I see myself interacting with Mozilla. I’m planning to write a series of posts describing the work underway in these areas. Please send comments or feedback or questions to “office of the chair mailing list.” And thanks for your interest in Mozilla.

The collapse of the press and the rise of anti-social media put democracy in peril

files/images/the-times-1400x788.jpg


Iain Martin, CapX, May 31, 2016


In this, "the final weekly newsletter from Iain Martin, Editor of CapX,"  the blame for the fall of media is laid squarely at the feet of social media, criticizing "those ostensibly up-market titles that opted for a friendly approach, cosying up to Facebook, pumping out more and more free rubbish," and of course, lamenting that "the tech giants blend inherent anti-conservatism, liberal elitism and hatred of regulation." 

My first visit to the UK was in 1976, long before the web and social media. I asked for a newspaper at my hotel room door. "Which newspaper?" I was asked. Well I would like world news, I replied. "How about News of the World?" Perfect! I said. Imagine my surprise to see a scandal rag complete with pinup girls the next morning.  Yes, the press may have outed the occasional politician, as Martin notes, but it has been an abject failure otherwise, completely ineffective in response to real world problems: environment, the concentration of wealth, militarization and corporate corruption.

Democracy was in peril long before the internet. We who turn to social media do so because there is no free press, and indeed, has  never been in our lifetimes. It certainly did not exist in my childhood, and the press of the present day slavishly prints whatever its well-heeled employers demand.

The man who inspired Google’s Project Ara pens critical blog post

by Rose Behar

Dave Hakkens, the man behind the explosively popular 2013 concept video that contributed to Google’s decision to try their hand at manufacturing modular devices, recently published a blog post titled “Rethink project Ara.”

Hakkens’ “Phonebloks” project is intent on inspiring manufacturers to contribute to the smartphone of the future, one in which defective elements can easily be swapped out to extend the lifespan of a device and reduce waste. While he’s pleased to see action on Project Ara, he’s unsure about the general direction the project seems to be taking.

In particular, Hakkens singles out the fact that the Ara frame Google showed at its recent I/O 2016 conference contains the full functionality of a smartphone, with the modules designed to be more accessory than necessity.

“It means your phone still gets obsolete after a while,” he says in his blog post, “What if your screen breaks? Well you still need to replace the entire phone. And after a couple of years it gets slow and you need to replace your entire skeleton.” 

In addition, he notes that Google owning Project Ara makes it far more of a closed development ecosystem than optimal.

“It isn’t truly open. Everything happens under the umbrella of Google. They are in charge, they make the rules. They can decided to suddenly change the connectors, or design. Making all previous modules you have obsolete.”

He also speaks to the issue of competing proprietary modules, which is antithetical to the Phonebloks ideal.

“A system like this makes other companies want to compete instead of collaborate. They will build their own modular phone, want to create their own ecosystem with their own sizes and connectors. Making modules not compatible with each other anymore,” writes Hakkens.

His advice?

“If Google truly wants to make a phone for the entire world, they should collaborate with others and make an open standard owned by the industry. Not one company.”

Thiel and Gawker

Elizabeth Spiers decides to stick her neck out for Gawker, the hard-to-like publisher wrestling with Peter Thiel, the gazillionaire apparently pissed off by coverage about him. [All emphasis mine.]

Elizabeth Spiers, On Peter Thiel and Gawker

[…] You have to admire Thiel’s sheer and apparently unending determination to make Denton and Gawker pay for coverage he didn’t like — it’s Olympic level grudge-holding. But the retribution is incredibly disproportionate in a way that seems almost unhinged. It would be hard to argue that Thiel was materially damaged by Gawker’s coverage in the way that he’s now trying to damage Gawker. His personal finances haven’t been destroyed and even the most egregious things Gawker has written haven’t put literally everyone who works for Thiel out of a job. (What did Lifehacker ever do to Peter Thiel?)

Even if Thiel wants to argue that Owen Thomas’s 2007 notorious “Peter Thiel is Totally Gay, People” post had a cataclysmically negative emotional toll for him, trying to destroy the entire business via abuse of the U.S. legal system still seems so epic in its vindictiveness that I couldn’t help but wonder whether this kind of asymmetrical reaction is just part and parcel of what you can expect in Thiel’s orbit generally, if you choose to do business with him.

[…]

It seems unreasonable to me. But then I’m not the kind of person who shows up with a gun when what the enemy really deserves is a good solid wedgie.

I’m struck by the fact that Thiel’s been an obvious screwball for a long time, and some of the oddest things he’s said haven’t reemerged in this contretemps. Thiel wrote a ‘personal statement’ for the Cato Institute where he wrote, 

I no longer believe that freedom and democracy are compatible.

He also suggests that woman’s suffrage was a bad thing:

Since 1920, the vast increase in welfare beneficiaries and the extension of the franchise to women—two constituencies that are notoriously tough for libertarians—have rendered the notion of ‘capitalist democracy’ into an oxymoron.

If you’re interested in that thread, see Jacob Weisberg’s What’s Wrong With Silicon Valley Libertarianism? , and my Peter Thiel, Techno-Utopian and  Beware Peter Thiel.

But this mindset not limited to Thiel. He’s just the most unabashedly aggressive member of the techno-utopian lunatic fringe. Here’s ex-Facebooker and angel Chamath Palihapitiya being interviewed by Jason Calcanis in 2013:

Palihapitiya: The government, they’re completely useless.

Calacanis: The government got shut down today and the stock market went up 1 percent.

Palihapitiya: We’re in this really interesting shift. The center of power is here, make no mistake. I think we’ve known it now for probably four or five years.

it’s becoming excruciatingly, obviously clear to everyone else that where value is created is no longer in New York, it’s no longer in Washington, it’s no longer in LA. It’s in San Francisco and the Bay Area. And when you look at sort of, like, how markets react to things like that, and when there’s no reaction, it should be taken as a very subtle signal that the power dynamics have changed. Because markets value meaningful events, markets discount meaningless events. And so the functional value of the government is effectively discounted to zero …

Companies are transcending power now. We are becoming the eminent vehicles for change and influence, and capital structures that matter. If companies shut down, the stock market would collapse. If the government shuts down, nothing happens and we all move on, because it just doesn’t matter. Stasis in the government is actually good for all of us. It means they can neither do anything semi-useful nor anything really stupid.

So why not highjack the courts for a personal vendetta? What’s to stop you, if you’re a billionaire with an ax to grind?

Communities Of Practice And Communities Of Experts

by Richard Millington

In a simpler world, we would create communities of top experts to collaborate with one another to advance their expertise to the cutting edge of their field.

If you’ve tried this, you know this only works if the community is exclusively for the top experts. It has to feel private, special, and a reward for their perceived level of expertise. That usually means a really small group which only benefits the experts, not the hosts.

This works as much on the fear of missing out as it does on a true belief to advance the field.

Experts are hard to reach (unless they consider you a true peer), hard to captivate, and hard to solicit regular contributions from. Experts often see fellow experts as rivals for a limited share of attention. They’re more likely to argue from a defensive position on the minutia of what one another has proposed. Worse yet, when a bigger opportunity appears for them to share their expertise, they tend to vanish.

The idea of creating a communities of experts is alluring, but in most cases impossible to create. You can waste a lot of time, money, and effort trying.

Far better to create a community of practice. Find a group of people who truly enjoy the topic, who truly want to help each other, and are doing the work every single day. Forget the experts and influencers. Unite a group of people who don’t know the answers, but will scour the web for one another looking for the answers.

Good questions trump good answers by a long way. Dull questions solicit dull responses. Good questions drive engagement and activity. You don’t need more experts, you need more people with good questions. People get more value from a committed group of equals, people enjoy participating more in a group of equals, and it’s far easier to build these communities.

Let the experts stop by if they want, but don’t focus on them.

Given the choice between trying to recruit people who know the answer or trying to recruit people who would love to find the answer, go with the latter…every single time.

Verso Tweets Break Windows

by Reverend

This is cross-posted on the CUNY Academic Commons News blog as part of the Citation Needed series I am writing there.

Thanks to a retweet from Tressie McMillan Cottom (one of the best academic wranglers of the blue bird), I got transported back to my days as a Ph.D. student at the CUNY Grad Center.

Verso Books (which has a very impressive Twitter presence, by the way) had the editors of Policing the Planet share their top 5 books about the broken windows theory of crime. I was intrigued and followed the link—nothing competes with a 90s cover of Time magazine for clickbait—and was struck by the first book on the list:

The late Neil Smith‘s The New Urban Frontier: Gentrification and the Revanchist City topped the list! That may have been the most formative book I read during grad school, and if I was smarter I would have taken the work I did with Smith on using 80s and 90s films to analyze the popular representation of gentrification pop culture and turned it into a dissertation. My official focus was on Early American impulses towards Imperialism, but my heart was always stuck in 80s. In fact, long after I dropped out of the CUNY Ph.D. program in English I published my paper on the topic on my vanity press of a blog: “Of Punks, Pimps, and CHUDs: Gentrification in NYC as told by 1980s Film.” I’m still sentimental about that one, and one of these days I need to return to it and replace some of the YouTube clips from the various films they so inconveniently took down.

Not only was it cool to a book near and dear to my heart inform current scholarship and resistance around policing the city. I was also struck by how effectively Verso uses Twitter not only to promote their books, but also share some great related titles. For example, the other four books that inspired the editors of Policing the Planet were (drumroll please)….

This is a solid list for anyone interested in a critical analysis of the history of policing, and I was struck how Verso made it interesting, accessible, and memorable. As I blog for the CUNY Academic Commons I find myself thinking about how this works. Is there a space where folks are promoting the various scholarship happening at the Grad Center? I mean Neil Smith has a rich history at the Grad Center, and Verso reminded me of that, what is the Academic Commons doing to regularly highlight the scholarship coming out of CUNY’s think tank?

Limited-time Rogers offer gives out an extra 3GB for new tablet activations

by Rose Behar

For Rogers customers who’ve been considering adding a tablet to their account, this might be a good time to do so. Currently, the carrier is offering a bonus 3GB of data for subscribers who activate select tablets with Easy Pay installments, outright tablet purchase or a BYOD line on a Share Everything plan.

To take advantage of this offer, subscribers must be on a Share Everything plan. Adding a tablet on Easy Pay to their plan will add $10 per month for the line, plus the monthly installment cost, which ranges from $10 for the LG G Pad III 8.0 to $37.50 per month for the iPad Pro.

The 3GB is strictly provisioned to the tablet, but if the tablet line exceeds that amount it can then dip in to the user’s Share Everything plan data allotment.

Additionally, Rogers is sweetening the pot with a two year subscription to Texture, an app that provides a library of over 150 magazines.

Update: We received some corrections and extra details from an in-the-know reader. The article has been updated accordingly. Thanks reader!

Twitter for iPhone Gets Extended 3D Touch Support with Peek & Pop

by Federico Viticci

With an update released earlier today on the App Store, Twitter has extended integration with 3D Touch in their iPhone app (previously limited to quick actions on the Home screen) to peek and pop previews in the timeline and other sections of the app.

With the latest version of Twitter for iPhone, you'll be able to press on tweets, links, pictures, and profiles to bring up a 3D Touch preview of the content. By swiping a peek upwards, you'll also gain access to shortcuts to either share via direct message and iOS extensions or, in the case of profiles, mute, block, and report a user.

Twitter's extended 3D Touch support isn't as advanced as Tweetbot – for instance, peek and pop previews don't seem to work in the Notifications tab – but it's a step forward regardless.

You can get the latest version of Twitter for iPhone from the App Store.

Microsoft’s Panos Panay talks about the death and rebirth of the Surface

by Patrick O'Rourke

Microsoft’s initial launch of the Surface was nothing short of a complete disaster for the company.

The first two tablet/laptop hybrid devices the Seattle, Washington-based tech giant released, the Surface RT and Surface Pro, failed to impress and were the butt of jokes in the tech industry when they launched in 2012.

While the original Surface Pro was viewed by some as an admirable attempt at creating a viable 2-in-1 laptop/tablet hybrid at the time, it was held back by Windows 8, its small 10.6-inch display size, ineffective keyless type cover and a variety of minor hardware issues.

The Surface RT on the other hand, sold so poorly that Microsoft was forced to take a $900 million “inventory adjustment” hit for the device, as well as its parts and accessories, back in July of 2013. Windows RT’s limitations didn’t connect with consumers, and neither did the Surface RT and its underwhelming Tegra ARM processor.

In a refreshingly candid discussion, Panos Panay, corporate vice president of devices and the head of Surface at Microsoft, admits the original Surface didn’t pan out as he hoped, despite his lofty ambitions for one of the company’s first cracks at designing its own hardware.

The moment news broke internally regarding Microsoft’s $900 million USD write-down of the RT, Panay says he remembers exactly what he was wearing, where he was standing, and who he was standing next to. According to him, it’s a time during his tenure as the Surface’s lead that he looks back at with a sense of fond nostalgia, but also pain.

microsoft-21

Microsoft’s Rachael Bell talks about designing the Surface Pro’s Signature Type Cover (made from Alcantara).

“It was a tragedy that I’ll never forget. It’s just ingrained, but it’s also a blessing. There’s something to that moment. It’s probably the most humbling thing this team has ever gone through,” said Panos Panay during an interview with MobileSyrup at Microsoft’s Surface development facility in Redmond, Washington. “I think it was needed and not necessarily unexpected. It was all about learning during that time.”

Immediately after Microsoft released the news to press the next day, following what he calls “weeks of sleepless nights,” Panay says he faced his team, the same group of individuals he spent months creating the Surface RT with. In Panay’s mind, this was a pivotal moment for the brand, emphasizing to his team how important the Surface is to the future of Microsoft and that the brand will continue despite this set back.

“You have a choice, stop rolling and get off the ship. Or keep your head down and believe in what we’re doing and lets go kick some ass,” said Panay. “They didn’t skip a beat. What they did do was learn. What they did feel was humility. They didn’t feel great, but you know what, they didn’t give up,” said Panay, discussing his team’s initial reaction to the Surface RT write-off.

microsoft-17

Microsoft’s distinguished scientist of applied sciences Steven Bathiche talks about testing the Surface Book and Surface Pro 4’s display technology.

“We knew what Surface Pro 3 was going to be when we were developing Surface Pro. That said, you can’t always get to the third generation with your first iteration,” said Panay, emphasizing that his team always had an ultimate goal in mind for the device.

Even with the early hiccups, Panay and his team still believed in what they were trying to accomplish with the Surface. They stayed the course with the hybrid device line, eventually landing on the Surface Pro 3, arguably the first Surface that accomplishes the line’s original laptop replacement vision.

Recent sales of Microsoft’s Surface line prove Panay’s and Microsoft’s decision to continue pushing forward with the Surface, was the correct course of action. In its most recent earnings report, Microsoft says Surface sales are up year-over-year, with the Surface Book and the Surface Pro 4 driving record Surface revenues in Q3, yielding the second $1 billion quarter in a row for the company and a 61% year over year increase to $1.1 billion.

microsoft-16

A quick look at the Windows Hello’s early development.

“We’ve had a lot of momentum over the last several quarters since we’ve launched Pro 4 and Book. We’ve had two billion dollar quarters in a row. We had our biggest quarter ever with Surface and we’ve seen 60 percent year over year growth,” said Panay “We’ve even seen competitors come in and challenge our concept, which I think is both flattering and challenging,” added Panay, referring to Apple’s iPad Pro laptop/tablet hybrid line, a device hindered by Apple’s current split operating system approach to devices, focusing on both iOS and OS X. Microsoft has, however, learned significantly from Apple’s approach to linking software and hardware on an integral level.

“We don’t want that seam between the hardware and the software. It needs to go away. We don’t want that barrier. I think historically you can feel the barrier between the device and its software and that’s changing. There’s really no such thing as a device and there’s really no such thing as software. They’re now just products,” said Panay.

Panay originally worked on mice and keyboards at Microsoft, but is now responsible for all of the company’s in-house developed devices, including the Surface Book, Microsoft Band 2, HoloLens and even the often-rumoured Surface Phone, if the last great hope for Windows 10 Mobile hasn’t been axed in the Microsoft’s recent cuts to the division (it likely has).

microsoft-13

A look at the ceiling of what Microsoft says is the quietest room in the world.

Panay believes that 2016’s expensive, high-end Surface Book, a device that actually initially began life as a standard laptop, is the result of everything he and his team learned during the development of earlier Surface devices.

“We started with just a laptop and were like ‘no way, no way, this is a Surface man.’ They’re looking at me [the team] like, ‘no we will not do this.’ They’d say, ‘Panay, if you put the product in the top the product gets too heavy, it’s impossible to get the weight tradeoffs,” said Panay, discussing the Surface team’s initial hesitation at creating a 2-in-1 designed to be more laptop-like than the Pro. “You can see all this come together in Book. It’s almost like a third-generation product in its first generation, as opposed to what Pro became with Pro 3, which is three generations in.”

Microsoft’s Surface development facility, a large unassuming building located in the company campus, is focused on iteration. Panay explains his team works through various versions and designs at a rapid pace thanks to a 24 hour development cycle linked to the company’s overseas factory production facilities.

“If we find a problem overseas, we can work on it in the morning here. By the time we fix it we can send the data and its on the line and the product is enhanced for it over night. I think this is something that’s unique to what we do here for Surface,” said Panay.

Taking a shot at Apple’s recent adoption of USB Type-C, Panay also says that his team chose not to adopt the new port format with the Surface Pro 4 or Surface Book because he feels USB Type-C, at least in right now, “isn’t fair.” He feels that despite the technology’s strengths, it hasn’t reached the point of consumer penetration where it should be included in a laptop.

Panay also says that the Surface line’s intent is to compete directly with Apple.

“Let me be clear. Our intent is to compete in the very premium market… We look at Apple as a key competitor to the Surface product line and that’s how we think about the product line. We want to give our customers more options in the premium space,” said Panay.

While the Surface initially seemed like an oddball device, a very Microsoft creation that was neither a competent computer, or a usable laptop, it’s evolved into a viable, premium computing product, a substantial portion of Microsoft’s business.

“We are investing more now than we ever have in the Surface business”

A Call for a Temporary Moratorium on The DAO

by Dino Mark and Vlad Zamfir and Emin Gün Sirer

The DAO is an exciting new construct: an investment vehicle governed by a program, directed by investors' votes, to seek out and fund proposals. Implemented as a smart contract on the Ethereum blockchain, The DAO has raised 11.5 million Ether, valued at $150 million at the time of writing. This is the largest crowd-funding event in history. The DAO now controls 16% of the total supply of Ether. It is arguably the most visible project in the Ethereum ecosystem.

We just released the first draft of a research paper that analyzed The DAO and its voting mechanism. This paper identifies problems with The DAO's mechanism design that incentivize investors to behave strategically; that is, at odds with truthful voting on their preferences. We then outline potential attacks against The DAO made possible by these behaviors.

In particular, we have identified seven causes for concern that can cause DAO participants to engage in strategic behaviors. Some of these behaviors can cause honest DAO investors to have their investments hijacked or committed to proposals against their interest and intent.

These concerns motivate a moratorium on funding proposals to prevent losses due to poor mechanism design. A moratorium would give The DAO time to make critical security upgrades. We encourage the community to adopt a moratorium until The DAO can be updated.

For expediency, we skip the background on The DAO and its mechanisms and jump right into the attacks. A primer on The DAO's operation can be found in the full paper.

Attacks and Concerns

The central point of the DAO is to enable token holders to vote on proposals. Every proposal has a clear present cost, specified in the proposal itself. It returns value to the shareholders either through an expected profit denominated in ether and paid back to The DAO, or through the implicit appreciation of the The Dao Tokens (TDTs). As with every investment, proposals to the DAO have a probability of success that depends on the nature of the venture and its business plan. For instance, a proposal may ask for 1000 Ether to make 1000 T-Shirts, and may estimate that they will sell them for 1.5 Ether each, to yield a total profit of 500 Ether over a few months, and thus estimate they will return 1500 Ether to The DAO. It is expected that vigorous debate and discussion during the voting phase will enable each voter to independently estimate the chances of success, and thus, the expected value (EV).

Good mechanism design dictates that the overall organization be constructed such that rational actors vote truthfully in accordance with their estimates of the expected value of each proposal. For the wisdom of the crowd to manifest itself, we would like a TDT holder to vote YES for a proposal that they believe has positive expected value (+EV), and NO for a proposal they believe has a negative expected value (-EV); alternatively, they may abstain if their vote is not going to change the outcome. We now describe why the current implementation of The DAO fails to uphold this principle.

  • The Affirmative Bias, and the Disincentive to Vote No

The current DAO has a strong positive bias to vote YES on proposals and to suppress NO votes as a side-effect of the way in which it restricts users’ range of options following the casting of a vote. Specifically, the current DAO restricts the ability of a token holder to split from the DAO once they have voted on a proposal until the outcome of the vote is determined. Thus, a voter who believes a proposal has negative expected value is in a quandary: they can split from The DAO immediately without taking any risk, or else they can vote NO and hope that the proposal fails to be funded. A NO vote is therefore inherently risky for an investor who perceives the proposal to be -EV, in a way that voting YES is not for a +EV voter. As a consequence, The DAO voting is likely to exhibit a bias: YES votes will arrive throughout the voting period, while a strategic token holder will want to cast their NO vote only when they have some assurance of success. Because strategic NO voters will cast their votes only after gaining information on others’ negative perception of the same proposal, the voting process itself will not yield uniform information about the token holders’ preferences over time. Preferences of the positive voters will be visible early on, but the negative sentiment will be suppressed during the voting process -- a problematic outcome for a crowd-funding organization based on measuring the sentiment of the crowd through votes.

  • The Stalking Attack

Splitting from The DAO (the only viable method of extracting one’s Ether holdings from the main DAO contract) is currently open to a “stalking attack.” Recall that a user who splits from The DAO initiates a new DAO contract in which they are the sole investor and curator. The intent is that a user can extract his funds by whitelisting a proposal to pay himself the entire contents of this sub-contract, voting on it with 100% support, and then extracting the funds by executing the approved proposal. However, recall that the split and the resulting sub-contract creation takes place on a public blockchain. Consequently, an attacker can pursue a targeted individual into such sub-contracts. Since a splitting user is the new curator of the nascent sub-contract, a stalker cannot actually steal funds; the stalkee can refuse to whitelist proposals by the stalker (though note that, due to potential for confusion and human error, the expected outcome from such attacks is still positive). If the stalker commits funds that correspond to 53% or more of the sub-contract, he can effectively block the stalkee from withdrawing their funds out of the contract back into ether. Subsequent attempts by the victim to split from the sub-contract (to create a sub-sub-contract) can be followed recursively, effectively trapping the victim’s funds and prohibiting conversion back to ether. The attacker places no funds at risk, because she can split from the child-DAO at any time before the depth limit is reached. This creates the possibility for ransom and blackmail. While some remedies have been suggested for preventing and counterattacking during a stalker attack, they require unusual technical sophistication and diligence on behalf of the token holders.

  • The Ambush Attack

In an ambush, a large investor takes advantage of the bias for DAO users to avoid voting NO by adding a large percent of YES votes at the last minute to fund a self-serving proposal. Recall that under the current DAO structure, a rational actor who believes a proposal is -EV is likely to refrain from voting, since doing so would restrict his ability to split his funds in the case that the proposal succeeds. This is especially true when the investor observes that sufficiently many NO votes already exist to reject the proposal. Consequently, even proposals that provide absurdly low returns to The DAO may garner NO votes that are barely sufficient to defeat them.

This kind of behavior opens the door to potential attack: A sufficiently large voting bloc can take advantage of this reticence by voting YES at the last possible moment to fund the proposal. Such attacks are very difficult to detect and defend against because they leave little to no time for The DAO token holders to withdraw their funds. Among the current DAO investors, there is already a whale who invested 888,888 Ether. This investor currently commands 7.7% of all outstanding votes in The DAO. For a proposal that requires only a 20% quorum, this investor already has 77% of the required YES votes to pass the proposal, and just needs to conspire with 2.3%+1 of the token holders, in return for paying the conspirators out from the stolen funds.

  • The Token Raid

In a token raid, a large investor stands to benefit by driving TDTs lower in value, either to profit from such price motion directly (e.g. via shorts or put options), or to purchase TDTs back in the open market in order to acquire a larger share of The DAO. A token raid is most successful if the attacker can (i) incentivize a large portion of token holders not to split, but instead sell their TDT directly on exchanges, and (ii) incentivize a large portion of the public not to purchase TDT on exchanges. An attacker can achieve (i) by implementing the stalker attack on anyone who splits and then making that attack public on social media. Worse, since the existence of the stalker attack is now well-known, the attacker need not attack any real entity, but can instead create fictitious entities who post stories of being stalked in order to sow panic among The DAO investors.

An attacker can achieve (ii) by creating a self-serving proposal widely understood to be -EV, waiting for the 6th day before voting ends, and then voting YES on it with a large block of votes. This action has the effect of discouraging rational market actors from buying TDT tokens because (a) if the attacker's proposal succeeds they will lose their money, and (b) they don’t have enough time to buy TDTs on an exchange and convert them back into Ether before the attacker's proposal ends, thus eliminating any chance of risk-free arbitrage profits. The combined result of (i) and (ii) means that there will be net selling pressure on TDT, leading to lower prices. The attacker can then buy up cheap TDT on exchanges for a risk free profit, because she is the only TDT buyer who has no risk if the attacking proposal actually manages to pass.

  • The extraBalance Attack

The extraBalance Attack is one in which an attacker tries to scare token holders into splitting from The DAO so that book value of TDT increases. The book value of TDT increases through splits because token holders who split can not recover any extraBalance, so the extraBalance becomes a larger percentage of the total balance, thus increasing the book value of the TDT. Currently the extraBalance is 203,257.65 Ether, which means the book value of TDT should be 1.02. If the Attacker can scare away half the token holders, the TDT will increase in value to 1.04. If the Attacker can scare away ~95% of the token holders, the book value of the remaining TDT will be roughly 2.00. In this attack, the attacking whale would do the opposite of the token raid by creating a self-serving proposal with a negative return and then immediately voting YES on it with a large voting block of TDT, thus scaring all the token holders, and then giving them 14 days until the end of the voting period so that they have more than enough time to safely split. In this scenario, splitting will be risk free (assuming that it is not coupled with a stalking attack), since voting NO could result in losses if the attackers end up having enough YES votes.

  • The Split Majority Takeover Attack

Even though the DAO white paper specifically identifies the majority takeover attack and introduces the concept of curators to deter it, it is not clear that the deterrence mechanism is sufficient. Recall that in the majority takeover attack outlined in the DAO whitepaper, a large voting bloc, of size 53% or more, votes to award 100% of the funds to a proposal that benefits solely that bloc. Curators are expected to detect such instances by tracking identities of the beneficiaries. Yet it is not clear how a curator can detect such an attack if the voting bloc, made up of a cartel of multiple entities, proposes not just a single proposal for 100% of the funds, but multiple different proposals. The constituents of the voting bloc can achieve their goal of emptying out the fund piecemeal. Fundamentally, this attack is indistinguishable “on the wire” from a number of investment opportunities that seem appealing to a majority. The key distinguishing factor here is the conflict of interest: the direct beneficiaries of the proposals are also token holders of The DAO.

  • The Concurrent Tie-Down Attack

The structure of The DAO can create undesirable dynamics in the presence of concurrent proposals. In particular, recall that a TDT holder who votes YES on a proposal is blocked from splitting or transferring until the end of the voting period on that proposal. This provides an attack amplification vector, where an attacker collects votes on a proposal with a long voting period, in effect trapping the voters' shares in The DAO. She can then issue an attacking proposal with a much shorter voting period. The attack, if successful, is guaranteed to impact the funds from the voters who were trapped. Trapped voters are forced to take active measures to defend their investments.

  • Independence Assumption

A critical implicit assumption in the discussion so far was that the proposals are independent. That is, their chances of success, and their returns, are not interlinked or dependent on each other. It is quite possible for simultaneous proposals to The DAO to be synergistic, or even antagonistic; for instance, a cluster of competing projects in the same space may affect each others’ chances of success and thus, collective returns. Similarly, cooperating projects, if funded together, might create sufficient excitement to yield excess returns; evidence from social science indicates that social processes are driven by non-linear systems.

Yet the nature of voting on proposals in The DAO provide no way for investors to express complex, dependent preferences. For instance, an investor cannot indicate a conditional preference (e.g. “vote YES on this proposal if this other proposal is not funded or also funded”). In general, the construction of market mechanisms to elicit such preferences, and appropriate programmatic APIs for expressing them, requires a more detailed and nuanced contract. This does not constitute an attack vector, but it does indicate that we might see strategic voting behavior even in the absence of any ill will by participants.

Potential Fixes

The preceding attacks have been discussed among a group of peers over the last 24 hours. Two potential fixes have emerged as uncontroversial.

Post-vote grace period: One potential mechanism that deters some of the attacks outlined above is to implement a post-vote grace period during which a proposal is accepted but not yet funded. This would provide token holders with a period of time during which they can withdraw their investment in case they perceive the outcome of the vote to decrease the value of the fund.

Instant Withdrawals: Offering instant and direct withdrawals of Ether to regular addresses would definitively eliminate the Stalker attack and weaken Token Raids. Many token holders currently seem to believe that they can withdraw from The DAO at any time. Guaranteeing that this can happen, without having to resort to complex defense mechanisms, would be a prudent next step.

Logistics of a Moratorium

The central take-away from our partial analysis and discussion is that it would be prudent to call for a temporary moratorium on whitelisting proposals so that reasonable measures can be taken to improve the mechanisms of The DAO. Therefore, we call on the curators to put such a moratorium in effect.

There are two alternatives to a curator-imposed moratorium. One is to ask The DAO token holders to place a self-imposed moratorium by voting down every proposal with overwhelming majority. Due to the flaws involving negative votes outlined in this paper, it would be a mistake to depend on this mechanism to protect against attacks targeting the same mechanism. The second alternative is to ask the DAO token holders to opt-in to the security measures by holding a vote for a new curator set who will implement a moratorium. We believe that The DAO’s default behavior should favor security. Since no one knows the percentage of non-voting, non-active token holders, the threshold required for curator changes may be too high for the voting process to meet. For these reasons, we believe that the safest course of action would be for the curators impose a moratorium, and allow the DAO token holders opt-out if they disagree by means of a curator change vote.

Summary

The preceding concerns motivate a moratorium on proposals to prevent losses due to poor mechanism design. A moratorium would give The DAO time to make critical security upgrades. We encourage the community to adopt a moratorium until The DAO can be updated.

Django, Pipeline, and Gulp

by Paul McLanahan

Bedrock, the code behind www.mozilla.org, is a very large Django project. It is mostly large due to the volume and diversity of independent pages it serves. These pages come with a surprising amount of static media (css, js, images, fonts, etc.). So, any system that we use to deal with said media should be efficient in order to keep our development servers fast.

We like django-pipeline for managing our static media in production. It does a great job of bundling, minifying, and compressing our css and js. When using it in a development environment however, it does not scale well. The issue is that it does not watch for changes to your files, so all it can do is copy them all from their source to the static directory on every page load. For a reasonable number of files this is probably fine, but as I said ours is not that. This is exasperated in slow I/O environments like Docker on a non-linux system (like OSX). We’ve not been able to setup an acceptable Docker-based local dev environment yet because it can literally take several minutes to render the home page.

Due to all of the issues noted above we’ve been looking for other ways of handling static media. We’ve considered a few times to move to a completely nodejs based system that would be completely independent of the Django side, and may still do that some day, but the problem has always been scope and impact. Again because the project is so large, making sweeping changes that affect workflow and all static files can both take a lot of time and be very disruptive when they land. So for a long time we figured we were stuck. But recently a conversation started in IRC about being able to just disable django-pipeline’s copying of files. If we could do that we could use gulp-watch to much more quickly and efficiently manage these files while being edited and still get the benefits of django-pipline for production. It turned out that someone else already had this idea and mostly we just needed to upgrade django-pipeline.

After that it was a simple matter of adding a task to our Gulpfile:

gulp.task('media:watch', function () {
    return gulp.src('./media/**/*')
        .pipe(watch('./media/**/*', {
            'verbose': true
        }))
        .pipe(gulp.dest('./static'));
});

But it was still a bit odd now having to have two shells open, one for the gulp task and another for the Django dev server. So we did a little more gulp magic and now have a single command to start up both the file watching and the Django server that combines the output of both in a single terminal.

gulp.task('serve:backend', function () {
    var devServerPort = process.env.PORT || 8000;
    process.env.PYTHONUNBUFFERED = 1;
    process.env.PYTHONDONTWRITEBITECODE = 1;
    spawn('python', ['manage.py', 'runserver', '0.0.0.0:' + devServerPort], {
        stdio: 'inherit'
    });
});

gulp.task('default', function() {
    gulp.start('serve:backend');
    gulp.start('media:watch');
});

You can see the full gulpfile.js in our repo on Github if you’d like. It’s a simple but very effective change and has made a very noticeable improvement in the speed of the local development server. And now we hope that we can finally complete and recommend Docker as the default setup for local development on bedrock.

CDC Director: Drug-Resistant Superbug Means “Medicine Cabinet Is Empty”

by Chris Morran
mkalus shared this story from Consumerist.

You know that scene in action movies where the hero has fired every bullet, thrown every piece of throwable furniture, set off every explosive, but still the bad guy lurches forward? At that point, there’s nothing left for the hero to do but run and pray. After the recent discovery in the U.S. of a bacteria that is resistant to a vital last-resort antibiotic, some scientists believe we’re inching dangerously close to that run-and-pray moment in the world of medicine.

“We risk being in a post-antibiotic world,” Dr. Tom Frieden, Director of the Centers for Disease Control and Prevention told reporters yesterday after military researchers confirmed the first-known U.S. instance of the MCR-1 gene, which provides antibiotic resistance to colistin, a drug of last resort. “That wouldn’t just be urinary tract infections or pneumonia — that could be for the 600,000 patients a year who need cancer treatment.”

Added Dr. Frieden, “The medicine cabinet is empty for some patients.”

For decades, doctors have treated multi-drug resistant bacteria with a class of antibiotics known as carbapenems. But the more you use a drug, the more the pathogens adapt to survive, so now there are carbapenem-resistant bacteria (CRE). Colistin, a potent antibiotic that had long been shelved because of its potential for kidney damage, has come back into use in recent years as a last-resort treatment for CRE infections.

While the bacteria found this month in the Pennsylvania woman is resistant to colistin and many other antibiotics, it is sensitive to carbapenems. However, now that the MCR-1 gene is stateside, some are very concerned that we’ll inevitably see bacteria that are resistant to both CRE and colistin.

“We are one step away from CRE strains that cannot be treated with antibiotics,” Dr. Lance Price, a researcher at George Washington University, tells the NY Times. “We now have all the pieces in place for it to be untreatable.”

Dr. Beth Bell of the CDC likens this fully resistant superbug to a nearly completed puzzle.

“You need lots of different pieces to get a result that is resistant to everything,” she explains to the Times. “This is the last piece of that puzzle, unfortunately, in the United States. We have that genetic element that would allow for bacteria that are resistant to every antibiotic.”

Bloomberg News today looks at the death of a child in India whose infection could not be treated by colistin.

“That is a warning to us that maybe we’re already losing this drug,” a hospital official tells Bloomberg. “If we lose colistin, we have nothing. It’s an extreme, extreme worry for us.”

Not every doctor is beating the doom-and-gloom drum about this discovery.

University of Pennsylvania hospital infectious disease specialist Neil Fishman tells Philly.com that the news is “not a death star, but a very strong warning that we really do have to be careful with antibiotics and use them optimally.”

While across town, Temple University Hospital specialist Tom Fekete cautions that he’s “not giving up the ship,” and notes that people have been declaring a “post-antibiotic world” for 20 years.

Earlier this month, the Pew Charitable Trusts released a report showing that now new types of antibiotics have been discovered in more than 30 years, raising the concern that resistance — in the absence of new drugs — could wipe out the utility of the ones we’ve been using since the golden ages of antibiotics research in the mid-Twentieth Century.

“This is definitely alarming,” said Pew’s David Hyun about yesterday’s announcement. “The fact that we found it in the United States confirms our suspicions and adds urgency to actions we need to work on antibiotic stewardship and surveillance for this type of resistance.”

The discovery of the MCR-1 gene in the U.S. has resulted in renewed calls for improved antibiotic oversight, particularly in farm animals, who consume the overwhelming majority of antibiotics in the country, primarily for the non-therapeutic purpose of growth-promotion.

“I have been sounding the alarm for years, and now, what we’ve been dreading has happened,” said Congresswoman Louise Slaughter of New York, who also happens to be a trained microbiologist. “We have an antibiotic-resistant superbug that can’t be killed by any known drug. We need swift, aggressive, global action to stop this in its tracks—now.”

“A modern nation state cannot be built on an ontological notion of who belongs and who does not, whether it’s outright ethnic or pseudo-cultural. It needs to build on the notion of the nation as a community — a community including those who were born here, those who came to stay and those who will stay for a while and then return to their homes. The rights and duties of the members of this community should be defined by their achievements, and by the rule of law — not by whether they eat schnitzel or wear a head scarf.”

Nexus 6P could be refreshed for 2016 with Snapdragon 820 and 4GB of RAM

by Patrick O'Rourke

While rumours continue to swirl that HTC will soon begin releasing devices under Google’s Nexus branding, new speculation indicates an upgraded 2016 version of the Nexus 6P is also in the works.

A recent listing on Geekbench indicates a new Nexus 6P could be on the way that features a Snapdragon 820 processor and 4GB of RAM, an upgrade over the 2015 Nexus 6P’s 3GB of RAM and Snapdragon 810 processor.

nexus

It’s unclear if this is just a mistake, someone messing with Geekbench’s database, or an actual prototype that’s legitimately been benchmarked. At I/O 2016, Google didn’t discuss the possibility of an upgraded 6P.

HTC’s upcoming two Nexus devices are reportedly code-named Marlin and Starfish, but very little is known about the devices so far.

Wil, Chris, Waffle, Samuel, Soroush

Wil Shipley:

So Cocoa programmers are in a tizzy A TIZZY I SAY at the prospect of going back to the bad old days (eg, 1987).

And…

I urge anyone who's speculating about Swift's possible future missteps to look hard at the team that's brought us LLVM, clang, ARC, and Swift, and think, “it’s pretty likely they’ll handle this,” not, “OH GOD EVERYTHING I LOVE IS ENDING.” (The latter of which, incidentally, is my nightly mantra.)

The tizzy is part of the process. I like to think that the various blog posts and Twitter discussions are contributions to a discussion rather than just words expended for no reason. It’s not venting or declaring that the sky for sure will fall — it’s people doing their part to think and communicate about tools that are important to them.

Also: 1987? For Wil, 1987 may have been the last of the bad old days. For other people, 1997 is more likely — but for me it was 2002, and for other people the bad old days are even more recent.

Consider Elm. People have talked it up to me, and it looks pretty cool, and I’m sure it’s awesome in a bunch of ways, and there are probably a bunch of things to learn from it.

But look at this small example of handling button presses. There are two buttons, and there’s a case (switch) statement to handle the message.

In a small example like this it doesn’t seem onerous. But an app is a much bigger thing, and doing this kind of thing everywhere would work me into a tizzy.

* * *

Chris Eidhof:

Yet, techniques you don’t know will almost always seem more complicated at first. I tried arguing with a Haskell programmer that runtime programming can be useful. I tried arguing with a Ruby programmer that static types can be helpful. To both, it seemed unnecessary and complicated. They’ve been writing great code without those features.

* * *

Waffle:

What I also expect is there to be a dialogue right now about these kinds of details by people who know what they’re talking about, about how Swift could actually become more dynamic without copying the flaws of its progenitors and without selling out the feel, mechanics and (most of the) performance of the language.

* * *

Samuel Ford:

My experience working with type strict frameworks is that they are fussy. It’s like if the only way you could chop things when cooking is with an array of specialty chopping tools that have to be assembled from pieces every time you needed them. And you have one for garlic, another for potatoes, and so on.

Every time you start to cook, you’ll feel the weight of taking those tools out, assembling the pieces, then taking them back apart, washing them, and putting them away. What you’ll find over time is that the recipes themselves will adapt to require fewer chopping tools and will become more plain and more similar over time.

* * *

Soroush Khanlou:

Primarily, the big thing I got wrong last year was that Swift is just plain fun. This weekend, I had the pleasure of helping a friend with code-review. His project is completely in Objective-C, and our code review session reminded me how rough the rough edges of that language are, especially after spending any time in Swift.

“I don’t know if I even believe in innovation”. The words escaped my mouth at an event I was speaking at this week. We were talking about innovative uses of technology in Further Education.

The Last Lion: Winston Spencer Churchill: Defender of the Realm, 1940-1965

A huge and brilliant volume, tightly focussed on a fascinating and witty statesman and his inner circle. Manchester was a captivating writer, and when a stroke prevented him from finishing the work, Reid stepped in and ably emulated Manchester’s skill at working detail into a compelling narrative. It’s a big book – 1200 pages, or 53 hours in Clive Chafer’s able reading – but it always moves right along.

Churchill seldom bought anything and carried no money; people did that for him, even though he was not rich until his war memoirs made him so. He only took the tube one time in his ninety year life, most of it spent in London. He was often hilarious and always eloquent, and he managed to stuff a hell of a lot of work into a day.

Independent Retail and the Death of the Mall

by pricetags

From the Portland Mercury:

Mall

Scotto di Carlo and her husband Michael are local economy experts and the founders of Supportland—a network of independent restaurants and retailers that employ a shared points system (sort of like a universal punch card) that provides an incentive for supporting local businesses.

“Retail is changing rapidly and the sort of discount shopper that [might have gone to the mall] is just going online,” says Scotto di Carlo. “The reason people engage with retailers now isn’t just because they want a product, it’s because they want to engage with a sense of place and their community.”

In its nascence, online shopping was an augmentation of brick-and-mortar retail—but now it’s the norm, placing malls like Lloyd Center in the unfortunate blind spot between independent boutiques and more upscale shopping centers.

In April, the Wall Street Journal reported that a variety of prominent chains are slowly withdrawing from weaker malls—and it isn’t hard to imagine Lloyd Center making that list.

“We’re kind of in this transitional period, but I think that the market footprint of big box stores and malls is going to be vacated at a higher and higher level as we approach this new equilibrium between online retail and [independent retail],” says Scotto di Carlo. “I don’t know if the old investors have given up completely, but I really don’t see how the target market is still going to be there for Lloyd Center.”

Scotto di Carlo also suggests that smaller businesses generally steer clear of spaces like the Lloyd Center, because they violate the values of independent retail by design.

“What malls did is they said, ‘Let’s zero out sense of place and let’s build a wall around our environment,’ and that was attractive initially to customers, but nowadays people are really yearning for a sense of place.”

Brilliance Is Better Than Magic, Because You Get To Learn It

by Eugene Wallingford

Brent Simmons has recently suggested that Swift would be better if it were more dynamic. Some readers have interpreted his comments as an unwillingness to learn new things. In Oldie Complains About the Old Old Ways, Simmons explains that new things don't bother him; he simply hopes that we don't lose access to what we learned in the previous generation of improvements. The entry is short and worth reading in its entirety, but the last sentence of this particular paragraph deserves to be etched in stone:

It seemed like magic, then. I later came to understand how it worked, and then it just seemed like brilliance. (Brilliance is better than magic, because you get to learn it.)

This gets to close to the heart of why I love being a computer scientist.

So many of the computer programs I use every day seem like magic. This might seem odd coming from a computer scientist, who has learned how to program and who knows many of the principles that make complex software possible. Yet that complexity takes many forms, and even a familiar program can seem like magic when I'm not thinking about the details under its hood.

As a computer scientist, I get to study the techniques that make these programs work. Sometimes, I even get to look inside the new program I am using, to see the algorithms and data structures that bring to life the experience that feels like magic.

Looking under the hood reminds me that it's not really magic. It isn't always brilliance either, though. Sometimes, it's a very cool idea I've never seen or thought about before. Other times, it's merely a bunch of regular ideas, competently executed, woven together in a way that give an illusion of magic. Regular ideas, competently executed, have their own kind of beauty.

After I study a program, I know the ideas and techniques that make it work. I can use them to make my own programs.

This fall, I will again teach a course in compiler construction. I will tell a group of juniors and seniors, in complete honesty, that every time I compile and execute a program, the compiler feels like magic to me. But I know it's not. By the end of the semester, they will know what I mean; it won't feel like magic to them any more, either. They will have learned how their compilers work. And that is even better than the magic, which will never go away completely.

After the course, they will be able to use the ideas and techniques they learn to write their own programs. Those programs will probably feel like magic to the people who use them, too.

five-minute geocoder for openaddresses

The OpenAddresses project recently crossed 250 million worldwide address points with the addition of countrywide data for Australia. Data from OA is used by Mapbox, Consumer Finance Protection Bureau, and my company, Mapzen.

Now, you can use OpenAddresses in a high-quality geocoder yourself. “Geocoding” is the process of transforming input text, such as an address, or a name of a place to a geographic location on the earth's surface. Every time you search for a destination on your phone, you’re geocoding. Mapzen’s Search service uses an open source server we call Pelias, and if you’re using the popular Ubuntu Linux operating system, you can get it set up and serving addresses in just a few minutes.

Start with a clean server running a current version of Ubuntu LTS (long-term support); either 14.04 or 16.04 will work. Amazon has readymade Ubuntu images available on EC2, or a local copy running under Virtualbox will do for testing. Both the address import process and the Elasticsearch index are hungry for lots of memory, so pick a server with 4-8GB of memory to prevent failures.

Next, install the Pelias software using instructions from OpenAddresses:

# Tell Ubuntu where to find packages:

# Install Pelias and dependencies:
apt-get update && apt-get install pelias

This installs the Pelias geocoder, the OpenAddresses importer, a simple web-based map search interface, and the underlying Elasticsearch index.

After installation, you will need to import data. Visit results.openaddresses.io and pick a processed zip file to download. Start small with a city like Berkeley, CA to test the process. Download and unzip it in the directory `/var/tmp/openaddresses` where Pelias expects to find CSV files, then run `pelias-openaddresses-import` to index the data.

# Get a sample file of address data:
cd /var/tmp/openaddresses
curl -OL https://results.openaddresses.io/latest/run/us/ca/berkeley.zip
apt-get install unzip && unzip berkeley.zip

# Index the addresses:
pelias-openaddresses-import

That’s it!

Pelias includes many neat features out of the box, such as reverse geocoding and autocomplete. Read the docs on Github.

The Mapzen Search service includes some additional features that aren’t yet covered here. For example, to include administrative areas like cities or states in searches, it’s necessary to do an admin lookup while importing, and to include data from Who’s On First. I’m also interested to learn more about tuning Elasticsearch for smaller-sized servers with less system RAM. It should be possible to run a geocoder with 1-2GB of memory, and Elasticsearch may require adjustments to make this possible.

Among Bruner’s beliefs: “President Barack Obama is a gay prostitute, climate change is a hoax concocted by Karl Marx and that Obama’s health care overhaul was an orchestrated plot to wipe 200 million people from the U.S. population. She also wrote that the flood from the biblical story of Noah’s Ark is what destroyed the dinosaurs, not a meteor as ‘concocted’ by atheists.” But yes please, Fordham Institute.

Education in the Courts


I was recently informed that my pointing out the relationships between politics, tech investors, and their investment portfolio constitutes an “ad hominem” attack. But you’re full of fallacy yourself if you think that’s going to stop me from making critiques about this industry. Good grief. And while this isn’t directly related to education, it’s one of the most important stories from the tech industry this week (one that certainly could have major implications on my ability to do my research and writing): that is, Paypal co-founder Peter Thiel apparently bankrolled the recent libel lawsuit that Hulk Hogan won against Gawker, using his vast wealth to – he hoped – put the publication out of business. More via The New York Times here and here and here and here. Here’s media reporter Mathew Ingram’s take (and there are lots of takes out there. My god. The takes). In addition to funding this lawsuit, Thiel sits on the board of Facebook, which itself is playing a huge role in the “future of news.” Thiel also a Trump supporter and will be a delegate at the upcoming Republican convention. (And Trump, for his part, also wants to make it easier to sue journalists for libel.) For those keeping score at home, here are Peter Thiel’s ed-tech investments (in addition to his “I’ll pay you to drop out of college” fellowship program, of course): Clever, Lore, Thinkful, Declara, and SoFi. He’s a partner at Founders Fund, which has invested in Knewton, AltSchool, Uversity, ResearchGate, If You Can, Upstart, Declara, and Affirm. But that’s all ad hominem and is irrelevant to the future of education. You wish.

Online Education (The Once and Future “MOOC”)


MOOCs for credit! FutureLearn announced that two UK universities – the University of Leeds and the Open University – will offer MOOCs that will be accepted for college credit. “In the Leeds offering, for example, each course certificate will cost £59 and there are five taught courses; the sixth assessment course, which leads to 10 credits, is priced at £250 – making a total cost of £545 – which will also cover access to online library content,” The Guardian reports. (It’ll be interesting to see if this offering is any more popular or any more successful than similar attempts in the US.)

The Math on Affordability

by pricetags

From Crosscut:

Crosscut

Seattle’s diehard “urbanists” can be remarkably single-minded in their advocacy for new and denser housing, but they aren’t necessarily wrong. In fact, according to some recent number crunching on San Francisco’s rental market, they’re essentially correct on what it’ll take to bring the city’s skyrocketing rents back down to earth.

The Washington Post recently highlighted an analysis of San Francisco’s rental market by Eric Fisher, a computer programmer with a laudable dedication to data-digging. Fisher combed through roughly 70 years of rent prices in San Francisco, cross-referencing them with the city’s economic history and policy changes to create a mathematical model for predicting rent hikes.

Adjusting for inflation, Fisher found that San Francisco’s rents have consistently risen about 2.5 percent a year, with only a few slight deviations. This, despite a period of population decline, the introduction of rent control in the late ‘70s, and a few tech booms and busts.

The basic conclusion of Fisher’s analysis is that it’s extremely hard to bring rents down in a prosperous city. Only two things can really accomplish it: more housing units, or fewer jobs — particularly high-paying ones. That’s it.

Fisher graph

One Twitter user summarized the study succinctly: “We can have Prosperity, Preservation or Affordability, but we can only pick 2.”
