Another way to look at Charlieplexing

by Mike Szczys

charlieplexing-with-buttons

Charlieplexing is a technique that allows you to drive a larger number of LEDs than wouldn’t be possible with the same number of I/O pins on a traditional multiplexed matrix. If we lost you there just think of it as lots of blinky lights connected to a small number of pins. It works by leveraging the one-way nature of a diode. Current will only flow through an LED in one direction so if you hook up your display in a clever way you can drive multiple LEDs from one I/O by switching the polarity of that pin between voltage and ground. [M.Rule] recently looked at using Charlieplexing with LED modules. His conceptual approach to the problem is different from those we remember seeing before and it’s worth a look.

Instead of just using the formula to calculate how many LEDs he can drive [M.Rule] is using a table of I/O pins to establish how many and in what order these displays can be connected. Each colored set of blocks represents an LED module. The graphic above shows how 18-pin can be utilized. He even filled in the unused pin combinations with input buttons.

The Inspector Gadget Tech That Ended Up Becoming Real

Back when many of us were still kids and many more had yet to even be twinkles in our mothers' uteri, Inspector Gadget was the apotheosis of all of technology's promises—many of which, it turns out, came true. Vanity Fair has a wonderful little collection of those gadgets of the inspector's that were particularly prescient.

Wildly Creepy Belgian PSA Actually Stole Someone's Identity

by Ashley Feinberg

You've undoubtedly been warned about how it easy it is to get your identity stolen online over. And over. And over again. But we just never learn. Clearly, it's going to take a little something more to hit the message home. Something like, oh, stealing an actual person's identity, terrifying him, and creating what might be the creepiest ad in modern memory.

Your Kids Are Smarter Than You: Toddler Buys Car On eBay Using Dad’s Smartphone

by Mary Beth Quirk

Winning something on eBay is such a thrill — except when you didn’t realize that you were even bidding because your toddler got her hands on your phone and oh my god, we own a car now that we didn’t before? That’s exactly what happened to one family after a little tyke got her hands on her dad’s smartphone, complete with the eBay app.

The dad tells ABC News he had no idea his daughter had done anything but play on his phone, until eBay sent him an exciting email.

“I didn’t realize until I got an email from eBay, basically saying congratulations,” he explains.

So what did he and his wife win? A 1962 Austin Healey Sprite, a small sports car. Gulp.

While at first the dad says they were a bit panicked, all’s well that ends well: Instead of getting out of it, the family decided heck, why not keep the car? It was only $225 after all, and will make for a great 16th birthday present for their daughter.

A lot more rewarding than say, a five-year-old kid accidentally spending $2,500 in online games on his parents’ iPad, right?

50 Debunked Science Misconceptions Will Make You Less Dumb

by Michael Hession

Being an enlightened individual means understanding basic scientific information about how the world works. Sure, we have teachers and parents there to fill our brains with knowledge, but the sad truth is that there are certain facts that take on a life of their own as they pass from ear to ear, eventually etching themselves into our collective brain-mass in twisted forms that are, well, just plain wrong.

Every Single Pair of Freaking Headphones Ends Up Like This

The timelapse of an untouched pair of headphones pretty much goes exactly like this comic. You set them aside totally mindful of the cables, carefully keeping them from each other. You ignore them until you need them again. And then when you pick them up, they're a tangled mess. Every. Single. Time.

Amazon Drops Price Of EC2 Dedicated Instances By Up To 80%

by Frederic Lardinois
aws-logo-640

Amazon today announced that it is dropping the prices of dedicated instances on its EC2 cloud computing platform by up to 80%. Dedicated per region fees, which are charged on top of the regular EC2 fees, will now set developers back $2 per hour instead of $10, for example. That’s a large price cut, even by Amazon’s standards – and the company has a long history of lowering the prices of its cloud computing services. Today’s price reduction, Amazon says, is an example of its “tradition of exploring ways to reduce costs and passing on the savings to our customers.” The new prices will be take effect on July 1 and will apply to all supported instance types and AWS regions.

Dedicated instances are different from regular EC2 instances, as they run on single-tenant hardware that is dedicated to just a single customer. These instances, the company says, “are ideal for workloads where corporate policies or industry regulations require that your EC2 instances be isolated from instances that belong to other customers at the host hardware level.”

Besides bringing down the region fee, Amazon is also dropping the price of dedicated on-demand instances – that is, instances that are paid by the hour without long-term contracts – by up to 37% (down from $0.840 to $0.528 for m1.xlarge instances in the US East region, for example). Dedicated reserved instances with long-term commitments are also now significantly cheaper as Amazon reduced the price of the upfront fees for this service by 57%.

Today’s announcement followed a somewhat smaller price drop for regular EC2 instances in April. Back then, Amazon dropped prices for Windows On-Demand instances by up to 26%.

Man’s Dreams Of Visiting Legoland Smashed Because He Didn’t Bring A Kid With Him

by Mary Beth Quirk

We’ve all got dreams. And while you might never have a vault filled with so many gold coins you can swim through it, one Canadian man thought it his bit of bliss was attainable with a visit to his local Legoland. Unfortunately for him, he made the mistake of not having a child with him when he showed up at a Toronto location after a three-hour drive.

The 63-year-old man and longtime lover of Lego has been a fan of the colored blocks since his children were young. As his kids grew up,  John has kept up his hobby — first by rebuilding all of their sets and then adding new ones for a total of about 75 sets, reports CTV News. He’s always wanted to visit the Legoland flagship location in Denmark, but that’s simply not possible because of various health problems.

Then, like a sign from the land of dreams fulfilled, John found a flyer for a Legoland Discovery Center three hours away near Toronto. He and his daughter planned, saved up, and went on a road trip to arrive at the Legoland’s doors — where they were turned away because adults must be accompanied by a child in order to get in.

“They wouldn’t let us go in and so we asked to see a manager,” his daughter said. “Five minutes later the employee came back and said the manager was too busy to see us, but that was their policy, they weren’t allowed in without a child and there was nothing they could do about it.”

The rule regarding adults and kids is posted on the location’s website — after clicking “Book Online” and then “More Information.” But that’s not something John would’ve thought to check, he says, as he’s not one to surf the Web.

“It made me feel awful. I felt discriminated against. I thought what the heck is the reason for this? If they gave me a reason maybe I could understand but they gave me no reason,” he said, adding that he didn’t want to go on any of the kids’ rides or build in the interactive section of the center. He just wanted photos of a Toronto skyline exhibit so he could try to build something like it.

The marketing manager of the location says if she had known about his visit, she would’ve brought him through as her guest, and is sorry that he left disappointed.

Instead, she pointed out that there are adults-only nights once a month for grown-up fans, but that on a daily basis, “it is a child attraction so we do have this in place to protect the families and children that visit.”

We hope you go back, John.

Why You Don't Remember Your Commute

by Thorin Klosowski

Why You Don't Remember Your Commute

We've all been there before: you snap out of a daze, look around, and realize you've driven all the way to your destination without really noticing it. It's a bit scary when you think about it, but it happens to all of us at some point. Here's what's going on.

The idea that we can forget about large chunks of time is unsettling, but it really just boils down to how we perceive time in general. In this particular case, it's about how time and memories are formed together. Neurologist David Eagleman uses this common example of the workday commute:

And that's of course what happens during a typical workweek or when you drive to work. You’re doing something that you do all the time. Time shrinks retrospectively. But if you go off for the weekend to some novel vacation, a place you’ve never been before, then you look back and you think, "Wow, that was very long weekend!"

The reason is simple: the longer it takes for our brain to process information, the longer the period of time feels. So, when the brain isn't doing a lot of processing, like, say, on your commute to work that never changes, the time it took to do so doesn't feel that long. One study from the Journal of Consumer Psychology suggests that the more attention we pay to an event, the longer the interval of time feels. Another study from the Journal of the Association for Psychological Science had similar findings.

It makes sense too. Think back to the last really great day you had. Chances are by the end of the day, you felt like full days had passed since you had breakfast. Now, think back to that morning commute. Despite the fact you were actually stuck in congested traffic and bored for much of it, it likely feels really short.

Speaking with David Eagleman, The New Yorker describes how memories and the perception of time work together like so:

“This explains why we think that time speeds up when we grow older,” Eagleman said—why childhood summers seem to go on forever, while old age slips by while we’re dozing. The more familiar the world becomes, the less information your brain writes down, and the more quickly time seems to pass.

Essentially, new experiences make it feel like time passed more slowly. In the moment, that commute may have felt like it was taking forever, but when it's done, it felt like it flew past. Think of it as though your commute has just a few prints of film in it to fill up a whole hour. When you play it back, you can watch the whole thing in 10 seconds. Now, think about that great vacation, all those memories fill up a lot more film, and thinking through those memories takes a lot longer than the commute. Effectively, that makes us perceive that time is actually extended.

So, how do you actually remember your commute? You'll need to recalibrate your reality a little and pay attention to the world around you. As we've mentioned before, you can increase your powers of observations with practice, and when you break out of your comfort zone you'll inevitably create a new set of memories that help you parse time better. Our attention is valuable, and when you use it to create memories, you're effectively making it seem like time stretches out. When you don't, it just flies by like your boring commute.

Farmer Sticking It To The Man By Refusing To Pay 1.2M Pounds Of Raisins Into National Reserve

by Mary Beth Quirk

There are some stories out there in the news that are just absolutely begging for puns. To wit: A raisin farmer in California is battling the government in a case of sour grapes, raisin’ a stink over the feds’ demands that he pay at least $650,000 in unpaid fines and hand over 1.2 million pounds of unpaid raisins into the national reserve. We heard it through the grapevine.

Or actually I read all about it in the Washington Post‘s article, appropriately titled “One grower’s grapes of wrath.”

The 68-year-old man has refused to fork over a portion of his raisin harvest into a reserve set up after World War II, and as such, has racked up more than half a million in fines. The farm program was created to keep demand for raisins high at a time when it was declining.

In order to prevent supply from outstripping demand, farmers would dump a bunch of their raisins in the national reserve each harvest. That way, consumers would still pay higher prices for raisins and farmers wouldn’t go out of business. But the raisins going into the reserve? Basically, the government got them for free.

“I believe in America. And I believe in our Constitution. And I believe that eventually we will be proved right,” the farmer said. “They took our raisins and didn’t pay us for them.”

Starting in 2002, he refused to hand over a percentage of his raisins, going against Marketing Order 989.

The government isn’t sitting atop giant piles of raisins, but it does store those crops in warehouses around California. The reserve is run by the Raisin Administrative Committee, which is allowed to sell off some of those reserve raisins… the ones it paid nothing for. Some might be sold to foreigners, or used to feed schoolchildren — whatever gets them off the open market and keeps the supply for commercial buyers low.

That means you could be paying higher prices for raisins than you would if the farmers were allowed to sell all their crops off.

Any money left over afterwards goes back to farmers, but the Washington Post notes that that isn’t often the case.

“We generated $65,483,211. And we pretty well spent it all,” said Gary Schulz, the committee’s president and general manager, reviewing the books for one recent year. That year, the committee spent those millions on storage fees. Overseas promotions. Administrative overhead.

So what, precisely, was left for the farmers?

“Zero,” said Schulz. “They received the value of our investment.”

The farmer was staked out by a private detective agency when he stopped handing over his raisins, resulting in a list of charges saying he’d broken the law.

“The respondents violated section 989.66 of the Order,” it said, in part. “By failing to hold in reserve . . . approximately 24.7 tons of Natural Sun-dried Seedless raisins.” There were 12 charges in all.

He’s now taken the case all the way up the court system stepladder, losing every time  — until he hit the big time with the U.S. Supreme Court. The justices also seem a bit puzzled by this whole raisin reserve system.

“What it does is it takes raisins that we grow — in effect, throws them in the river,” Justice Stephen G. Breyer said. “I can’t believe that Congress wanted the taxpayers to pay for a program that’s going to mean they have to pay higher prices” for raisins, he added.

The court ruled this spring that the 9th Circuit in California must settle the case. If he loses, he’ll owe the government about $3 million, he guesses.

“If we lose, we’re bankrupt. We won’t have a pot to piss in,” the farmer said.

For now, at least, he won’t have to fork over any more raisins into the reserve, and neither will other farmers: The Agriculture Department and the Raisin Administrative Committee have agreed that no new raisins should be put into the reserve over the past three years.

Tweaking your Windows 7/XP Desktops on VDI

by Carlo Costanzo

My buddy John Simon has put together some common tweaks he uses for for his company’s Virtual Desktops.  These are easy tweaks that can be used in VMware View and Citrix XenDesktop desktops but are sometimes forgot.  Pop them into your VM template and reap the performance benefits.  Some can also be used on your local machine for some enhanced performance.

Disable hibernation by running the command powercfg /hibernate off from the command line (WIN7/XP):image

Set the windows page file to a static number. By default windows will grow and shrink the page file which will cause an I/O overhead. This value should be 1.5 x the amount of system RAM with a limit of 4096 for a 32bit operating system (WIN7/XP):

image

Disable indexing by going to properties of the C drive and un-checking the box to allow indexing service to index this disk for fast file searching (WIN7/XP):

image

Disable the boot graphic, this graphic is not needed for a virtual machine and just consumes resources. To do this click on start and then run and run msconfig. From the pop up window, click on the boot tab and then check the box for NO GUI BOOT (WIN7/XP):

image

Uninstall Tablet PC Components by going to control panel – programs and features and select turn windows features on or off then remove the checkbox by Tablet PC components (WIN7):

image

Finally you should disable logging on the VM from the VM settings menu. This can be done by going to the options tab of the virtual machine properties (WIN7/XP):

Have any favorites that aren’t GPO’s? (Sample GPO to come in a later post).  Post in the comments.

EMC’s HAVT utility tip

by Carlo Costanzo

image

If you’ve launched the High Availability Verification Tool before from Unisphere, you might have seen a similar “does not support high availability” message.  If everything checked out fine and you are now searching frantically on the interwebs for an answer, don’t worry, you are probably just running an iSCSI configuration with your vSphere environment.

image
This server [ESX HOST] has only one HBA (host bus adapter) and does not support high availability.

You can safely ignore this error.  The issue involves the way the HAVT tests for high availability on a host.  The tool is a hold over from a Fiber Channel only world where 2 HBAs were the minimum requirement for high availability status.  With iSCSI, even when you have two NIC cards in your ESX hosts, the IQN name is the same for both NICs and the array thinks you have only one adapter and therefore unable to support high availability.  

You DO want to check to verify that you are seeing multiple PATHs to the array though from the ESX hosts.  For that, look at the properties of the iSCSI software adapter in Storage Adapters on each ESX hosts' configuration tab to validate that you are able to see the appropriate redundant paths per ESX server [usually 8].

BTW: I really had no reason to include the racks of EMC VNXs at the top of this blog post but come on … Check out those blue lights! How could I not?

10 Years Ago, Opportunity Rover Began a 90-Day Mission That Never Ended

10 Years Ago, Opportunity Rover Began a 90-Day Mission That Never Ended

When NASA's Opportunity rover launched on July 7th, 2003, expectations were modest. It would spend 90 Martian days exploring soil and rock samples and taking panoramas of the Red Planet; anything else would be a bonus. Nearly ten years after its initial shift was up, Opportunity is still going strong.

Ubisoft Warns Account Holders Of Security Breach Affecting Personal Information

by Mary Beth Quirk
Change your passwords, people.

Change your passwords, people.

If you’ve got an account with Ubisoft, you should probably change your password lickety-split to something super secure. The video game company announced today that an intruder gained illegal access to some of its online systems. While Ubisoft says it’s closed off the breach, data like email addresses, encrypted passwords and user names was accessed.

In a blog post on the company site, Ubisoft says it’s started a thorough investigation while assuring account holders that since no  credit/debit information is stored by Ubisoft, that info is safe.

Ubisoft is recommending that users not only change their password on their site, but anywhere else on the Web where you use a similar or identical password.

“We sincerely apologize for any inconvenience that this may cause and we would like to thank you for your understanding,” the statement reads.

In the meantime, “Ubisoft’s security teams are exploring all available means to expand and strengthen our security measures in order to better protect our customers. Unfortunately, no company or organization is completely immune to these kinds of criminal attacks.”

For more information check out Ubisoft’s full post and Q&A section in the source link below.

New Grand Theft Auto Game Will Steal 8GB Of Your Xbox 360′s Hard Drive Thanks To Mandatory Install

by Chris Morran

1280First the good news about the upcoming Xbox 360 version of GTA V (or Grand Theft Auto 5, if you’re not into the whole brevity thing) — even though it’s shipping on two discs, you’ll be able to play the whole game without swapping discs in and out. The bad news, especially for those with smaller or full-up hard drives — GTA V will require that you install the entire 8 GB of the first disc, whether you want to or not.

While this is not a huge problem for users with ample hard drive space, people with the 4 GB versions of the console will need to add a USB drive to their Xbox just to play the game.

The 4 GB Xbox is still available for sale and, with a price tag of only $199, is a popular choice for casual gamers. As of today, it’s the top-selling version of the console available on Amazon. The Xbox 360 initially required the purchase of proprietary hard drives for people looking to store downloaded content, but Microsoft later eased that requirement to allow USB flash drives.

“In order to provide the best possible experience for such a massive and detailed world, the game will have installation requirements on both Xbox 360 and PlayStation®3 systems,” writes publisher Rockstar games in a Q&A on the game. “For Xbox 360, Grand Theft Auto V will ship on two discs; Disc 1 will be used for a one-time mandatory install and Disc 2 will be used to play the game…

“This initial install will require an Xbox 360 Hard Drive or an external 16GB USB flash drive with at least 8 GB of free space. If using a USB flash drive it must be at least USB 2.0 with a minimum 15mb/s read speed and formatted for Xbox 360 use. A new USB flash drive is recommended to ensure optimum performance.”

So by adding this install requirement into the game, Rockstar is effectively increasing the price for users who have to go out and purchase an adequate USB flash drive to store this game.

The PS3 version of the game, which only requires one disc, will auto-install on the console before it can be played. PS3 users without sufficient hard drive space will need to make room if they want to play GTA V.

Bacteria completes epic Unity project, crams 15 consoles in one

Bacteria completes epic Unity project, crams 15 consoles in one

When it comes to modding consoles there are two names that generally stand above the rest: Mr. Benjamin J. Heckendorn and the man known as Bacteria. The latter has done his fair share of portable machines, but his latest completed project takes console hacking to lofty new heights. Unity crams a stunning 15 different consoles (including classics like the SNES and not-so-classics like the TurboGrafx 16) into a single, admittedly bulky box. The one of a kind entertainment center is the culmination of three years and $700 invested in bringing this dream to life. All of the hardware inside is either from the original consoles (no emulation of clone systems here!) or custom built -- such as the 16-position switch. And, it should go without saying, that it took a whole lot to get these gaming machines to share a single power supply, video cable and control pad. Now that the epic project is finally complete Bacteria has provided a rather lengthy walk though of all the various features and the work that went into it, which you can check out after the break.
