NASA's New Horizons spacecraft has a new destination: a 30-mile-wide chunk of ice - Vox

NASA's New Horizons probe, which completed an unprecedented flyby of Pluto in July, has a new destination: a 30-mile-wide chunk of ice known as 2014 MU69 that orbits nearly a billion miles farther out.

Scientists have always planned for the spacecraft to visit to another Kuiper belt object (KBO) — one of the thousand or so pieces of rock and ice that orbit the sun in a cloud beyond Neptune. Today, NASA announced that New Horizons scientists selected 2014 MU69 instead of the other destination in consideration, a similar KBO called 2014 PN70.

NASA still has to officially approve this secondary mission, but all indications are that it will. If everything goes to plan, the spacecraft should reach this distant destination in January 2019.

Why New Horizons is going to visit a Kuiper belt object

(NASA)

After its Pluto flyby, New Horizons is continuing on to 2014 MU69, labeled here as PT1 (for "Potential Target 1").

Many of us imagine Pluto to be at the outer edge of the solar system. But in reality, it's just one of the largest of thousands of Kuiper belt objects. And from the start, NASA planned for New Horizons to fly by another one of these after Pluto: It was sent off with enough fuel to do so, and for the past year, scientists have been using the Hubble Space Telescope to spot potential targets.

Why visit two Kuiper belt objects? Mainly because we know so little about the Kuiper belt as a whole — and because the composition of these KBOs might tell us a lot about the original formation of the whole solar system.

KBOs were formed about 4.6 billion years ago, when Earth and the other planets were created, as well. But for unknown reasons, as Earth continued to grow larger, Pluto stopped growing and was flung outward, perhaps along with many other Kuiper belt objects.

That means that their contents could serve as a sort of frozen time capsule of the early solar system. We've now studied some of the smallest ones (comets, which have extremely elliptical orbits that occasionally bring them closer to Earth) and one of the largest ones (Pluto). Visiting a midsize object like 2014 MU69, New Horizons principal investigator Alan Stern told me before the Pluto flyby, "will really help us connect the dots."

To get there, mission scientists will direct New Horizons to fire its thrusters in October, to slightly alter its trajectory and set it on the proper course. When it flies by the KBO in 2019, it'll take photos and collect other sorts of scientific data to beam back to Earth. After that, New Horizons will keep on flying — but with no subsequent destinations planned, it'll just travel alone, advancing toward the outer reaches of the solar system until its power runs out sometime in the 2030s.

How to Deal With Embarrassment

by Scott Meyer

This is not a comic I would—or even could—produce now. For one thing, I wouldn't make a comic with four panels’ worth of pee jokes now. (One, yes. Four, no.) For another, I learned pretty early on that having the four panels depict four different versions of the same conversation is confusing, and it's best to just have the panels occur sequentially.

Mostly, though, it's just that it's been years since I wrote anything this concise.

Missy looked at the comic and pointed out that I have my hands in my pockets, which looks weird to her. What can I say, hands are hard. At least I have hands. That other guy doesn’t seem to have arms!

Pluto in Enhanced Color

Explanation: Pluto is more colorful than we can see. Color data and images of our Solar System's most famous dwarf planet, taken by the robotic New Horizons spacecraft during its flyby in July, have been digitally combined to give an enhanced view of this ancient world sporting an unexpectedly young surface. The featured enhanced color image is not only esthetically pretty but scientifically useful, making surface regions of differing chemical composition visually distinct. For example, the light-colored heart-shaped Tombaugh Regio on the lower right is clearly shown here to be divisible into two regions that are geologically different, with the leftmost lobe Sputnik Planum also appearing unusually smooth. New Horizons now continues on beyond Pluto, will continue to beam back more images and data, and will soon be directed to change course so that it can fly past asteroid 2014 MU69 in 2019 January.

Prefeitura de SP adota home office

by Juliana Franzon

A partir de setembro os funcionários da Prefeitura de São Paulo estão liberados para trabalhar em casa. O sistema home office será adotado na Secretaria de Finanças de Desenvolvimento Econômico com o objetivo de reduzir custos de infraestrutura e aumentar a produtividade.

Os servidores que cuidam do sistema de computadores da Prefeitura serão os primeiros a testar o novo modelo. Aqueles que forem escolhidos para fazer home office terão uma meta de desempenho 20% maior do que a de quem fica no escritório e devem se organizar para trabalhar entre 8h e 19h, mesmo em casa. Será exigido também que o colaborador cumpra pelo menos 8 horas por semana nas dependências da Prefeitura.

A frequência, explica o secretário Rogério Ceron de Oliveira, será controlada através do acesso do servidor ao sistema eletrônico, onde será possível monitorar se de fato está sendo desempenhada a atividade.

Não poderão trabalhar de casa os funcionários que tenham sido repreendidos ou suspensos nos últimos dois anos, nem aqueles que tiveram faltas injustificadas nos últimos 12 meses.

A adoção do sistema home office está sendo vista com otimismo na Secretaria. “Às vezes, no trabalho do dia a dia, a gente precisa ficar mais focado, concentrado. Eu acho que em casa conseguimos fazer isso melhor”, disse Paula Piantino Vitiritti, uma das servidoras do setor. “É importante não ficar isolado, vir com frequência e trabalhar em equipe como a gente costuma”, acrescentou Lucas Marques.

Alice & The Queen - The Luck Of The Draw

by Zeon Santos


Alice & The Queen by Kellabell9

Someone once presented the theory that Alice and the Queen of Hearts are simply two sides of the same card, one oriented towards positivity the other pointed towards Wonderland's underworld. This theory has been debated by mad hatters and brilliant philosophers alike, but they all run headlong into one fatal flaw in this logical leap- Alice is hunted by the Queen, and would lose her head if Alice had her way, but can such a narcissistic soul truly desire to destroy herself?

Deal yourself a winning hand with this Alice & The Queen t-shirt by Kellabell9, it's a bright and colorful design that's sure to drive your fellow fans wild!

Gay Teen Worried He Might Be Christian

Adam Victor Brandizzi

Always reshare.

LOUISVILLE, KY—At first glance, high school senior Lucas Faber, 18, seems like any ordinary gay teen. He's a member of his school's swing choir, enjoys shopping at the mall, and has sex with other males his age. But lately, a growing worry has begun to plague this young gay man. A gnawing feeling that, deep down, he may be a fundamentalist, right-wing Christian.

"I don't know what's happening to me," Faber admitted to reporters Monday. "It's like I get these weird urges sometimes, and suddenly I'm tempted to go behind my friends' backs and attend a megachurch service, or censor books in the school library in some way. Even just the thought of organizing a CD-burning turns me on."

Added Faber, "I feel so confused."

The openly gay teen, who came out to his parents at age 14 and has had a steady boyfriend for the past seven months, said he first began to suspect he might be different last year, when he started feeling an odd stirring within himself every time he passed a church. The more conservative the church, Faber claimed, the stronger his desire was to enter it.

"It's like I don't even know who I am anymore," the frightened teenager said. "Keeping this secret obsession with radical right-wing dogma hidden away from my parents, teachers, and schoolmates is tearing me apart."

Faber's sock drawer is home to a number of illicit magazines he has secretly accepted from street preachers.

According to Faber, his first experience with evangelical Christianity was not all that different from other gays his age.

"Sure, I looked at the Book of Leviticus once or twice—everybody has," Faber said. "We all experiment a little bit with that stuff when we're growing up. But I was just a kid. I didn't think it meant anything."

Faber's instinct was to deny these early emotions. But recently, the Louisville teen admitted, the feelings have grown stronger, making him wonder more and more what life as a born-again right-wing fundamentalist would be like.

"The other week, I was this close to picketing in front of an abortion clinic," the mortified teenager said, his eyes welling up with tears. "I know it's wrong, but I wanted so badly to do it anyway. I even made one of those signs with photos of dead fetuses and hid it in my closet. I felt so ashamed, yet, at the same time, it was all strangely titillating."

Faber's parents, although concerned, said they're convinced their otherwise typical gay son is merely going through a conservative Christian phase.

"I caught him watching The 700 Club once when he thought he was alone in the house, and last week, I found some paperbacks from the Left Behind series hidden in his sock drawer," his mother, Eileen Faber, said. "I'm sure he'll grow out of it, but even if he doesn't, I will love and accept my son no matter what."

Faber's father was far less tolerant in his comments.

"No son of mine is going to try to get intelligent design into school textbooks," Geoffrey Faber said. "And I absolutely refuse to pay his tuition if he decides to go to one of those colleges like Oral Roberts University where they're just going to fill his head with a lot of crazy conservative ideas."

He added, "I just want my normal gay son back."

Software Development Anywhere: My Distributed Remote Workplace

by IVAN VORAS, SOFTWARE ENGINEER @ TOPTAL
Adam Victor Brandizzi

Nice setup.

Working as a remote freelancer has many benefits, but setting up an effective distributed working environment can be a real challenge. Of course, there are many approaches that one can take, and no single “best” way will suit everyone. Remote digital workplace organization is indeed a very personal thing, and what works well for one developer may not work well at all for someone else.

With that in mind, the setup I present here is simply what works well for me personally, especially on remote projects that involve both development and system administration. I do believe this approach has a number of advantages, but each reader should consider how to adapt this in a way that works best for them, based on a combination of their operational needs and personal preferences.

My approach is largely based on features offered by SSH and related tools on Linux. Note that users of MacOS and other Unix-like systems can take advantage of the described procedures as well, to the extent that their systems support the described tools.

My Distributed Remote Workplace

My Own Personal Mini-Server

An important first step in my setup is a Raspberry Pi 2-powered server in my own home, used to host everything from my source code repositories to demo sites.

Although I do travel, my apartment does serve as my remote “fixed base of operations” with decent Internet connectivity (100 Mbit/sec) and almost no additional latency. This means that, from my apartment, I am basically constrained only by the destination network’s speed. The setup I’m describing works best with this type of connectivity, though it’s not a requirement. In fact, I have also used this approach while I had a relatively low-bandwidth ADSL connection, with most things working just fine. The only real requirement, in my experience, is that the bandwidth either be unmetered or dirt cheap.

As a residential user, I have the cheapest home network router my ISP could buy, which simply isn’t enough for what I need to do. I have therefore requested that the ISP put the router into “bridge mode”, where it only serves as a connection terminator, offering a PPPoE end-point to exactly one connected system. This means the device stops working as a WiFi access point or even as a common home router. All these tasks are handled by a professional small Mikrotik router RB951G-2HnD. It performs the NAT service for my local network (which I’ve numbered 10.10.10.0/24), and offers DHCP to wired and wireless devices connected to it. The Mikrotik and the Raspberry Pi have static addresses because they are used in contexts where a well-known address is required. In my case, those are 10.10.10.1 and 10.10.10.10, respectively.

My home connection doesn’t have a static IP address. For my purposes, this is only a mild inconvenience working remotely since the goal is to create a personal or SOHO working environment, not a 24/7 site. (For those who do require a static IP address for their server, it is worth noting that the cost of static IP addresses has continued to come down and fairly inexpensive static VPN IP options are available.) The DNS broker I use, Joker.com, offers a free dynamic DNS service alongside all of its other services, so one subdomain of my personal domain exists as a dynamic name. I use this name for connecting from the outside to my own network, and the Mikrotik is configured to pass SSH and HTTP through the NAT to the Raspberry Pi. I simply need to type the equivalent of ssh mydomain.example.com in order log in to my personal home server.

Data Anywhere

One significant thing which the Raspberry Pi does not offer is redundancy. I’ve equipped it with a 32 GB card, and that’s still a lot of data to lose in case something happens. To get around that, and to ensure access to my data if the residential Internet access hiccups, I mirror all my data to an external, cloud-like server. Since I’m in Europe, it made sense for me to get the smallest dedicated bare-metal (i.e. unvirtualized) server from Online.net, which comes with a low-end VIA CPU, offering 2 GB RAM and a 500 GB SSHD. As with the Raspberry Pi mini-server, I don’t need high CPU performance or even memory, so this is a perfect match. (As an aside, I remember my first “big” server which had two Pentium 3 CPUs and 1 GB of RAM, and was probably half the speed of the Raspberry Pi 2, and how we did great things with it, which has influenced my interest in optimization.)

I back up my Raspberry Pi to the remote cloud-like server using rdiff-backup. Judging from the relative sizes of the systems, these backups will get me virtually unlimited history. One other thing I have on the cloud-like server is an installation of ownCloud, which enables me to run a private Dropbox-like service. ownCloud as a product is moving toward groupware and collaboration, so it becomes even more useful if more people are using it. Since I started using it, I literally don’t have any local data that is not backed up to either the Raspberry Pi or to the cloud-like server, and most of it is backed up twice. Any additional backup redundancy you can make is always a good thing, if you value your data.

The “Magic” of SSHFS

Most of my work these days involves developing stuff which is not directly web-related (shocking, I know!), so my workflow often follows a classic edit-compile-run cycle. Depending on the specific circumstances of a project, I may either have its files locally on my laptop, I may put them in the ownCloud-synced directory, or, more interestingly, I might place them directly on the Raspberry Pi and use them from there.

The latter option is made possible thanks to SSHFS, which enables me to mount a remote directory from the Raspberry Pi locally. This is almost like a small piece of magic: you can have a remote directory on any server you have SSH access to (working under the permissions your user has on the server) mounted as a local directory.

Have a remote project directory? Mount it locally and go for it. If you need a powerful server for development or testing and – for some reason just going there and using vim in the console is not an option – mount that server locally and do whatever you want. This works especially well when I’m on a low-bandwidth connection to the Internet: even if I do work in a console text editor, the experience is much better if I run that editor locally and then just transfer the files via SSHFS, rather than working over a remote SSH session.

Need to compare several /etc directories on different remote servers? No problem. Just use SSHFS to mount each of them locally and then use diff (or whatever other tool is applicable) to compare them.

Or perhaps you need to process large log files but you don’t want to install the log parsing tool on the server (because it has a gazillion dependencies) and for whatever reason copying the logs is inconvenient. Once again, not a problem. Just mount the remote log directory locally via SSHFS and run whatever tool you need – even if it’s a huge, heavy, and GUI-driven. SSH supports on-the-fly compression and SSHFS makes use of it, so working with text files is fairly bandwidth-friendly.

For my purposes, I use the following options on the sshfs command line:

sshfs -o reconnect -o idmap=user -o follow_symlinks -C server.example.com:. server

Here’s what these command line options do:

  • -o reconnect - Tells sshfs to reconnect the SSH end-point if it breaks. This is very important since by default, when the connection breaks, the mount point will either fail abruptly or simply hang (which I found to be more common). Really seems to me that this should be the default option.
  • -o idmap=user - Tells sshfs to map the remote user (i.e., the user we are connecting as) to be the same as the local user. Since you could connect over SSH with an arbitrary username, this “fixes” things so the local system thinks the user is the same. Access rights and permissions on the remote system apply as usual for the remote user.
  • -o follow_symlinks - While you can have an arbitrary number of mounted remote file systems, I find it more convenient to mount just one remote directory, my home directory, and in it (in the remote SSH session) I can create symlinks to important directories elsewhere on the remote system, like /srv or /etc or /var/log. This option makes sshfs resolve remote symlinks into files and directories, allowing you to follow through to the linked directories.
  • -C - Turns on SSH compression. This is especially effective with file metadata and text files, so it’s another thing that seems like it should be a default option.
  • server.example.com:. - This is the remote end-point. The first part (server.example.com in this example) is the host name, and the second part (after the colon) is the remote directory to mount. In this case, I’ve added “.” to indicate the default directory where my user ends up after the SSH login, which is my home directory.
  • server - The local directory into which the remote file system will be mounted.

Especially if you are on a low-bandwidth or an unstable Internet connection, you need to use SSHFS with SSH public/private key authentication, and a local SSH agent. This way, you will not be prompted for passwords (either system passwords or SSH key passwords) when using SSHFS and the reconnect feature will work as advertised. Note that if you don’t have the SSH agent set up so it provides the unlocked key as needed within your session, the reconnect feature will usually fail. The web is full of SSH key tutorials, and most of the GTK-based desktop environments I’ve tried start their own agent (or “wallet”, or whatever they choose to call it) automatically.

Some Advanced SSH Tricks

Having a fixed point on the Internet which is remotely accessible from anywhere in the world, and which is on a high bandwidth connection – for me it’s my Raspberry Pi system, and it really could be any generic VPS – reduces stress and allows you to do all sorts of things with exchanging and tunneling data.

Need a quick nmap and you’re connected over a mobile phone network? Just do it from that server. Need to quickly copy some data around and SSHFS is an overkill? Just use plain SCP.

Another situation you may find yourself faced with us where you have SSH access to a server but its port 80 (or any other) is firewalled out to the outside network from which you connect. To get around this, you can use SSH to forward this port to your local machine, and then access it through localhost. An even more interesting approach is to use the host to which you are connected over SSH to forward a port on another machine, possibly behind the same firewall. If, for example, you have the following hosts:

  • 192.168.77.15 - A host in the remote local network behind a firewall, to which you need to connect to its port 80
  • foo.example.com - A host you have SSH access to, which can connect to the above host
  • your local system, localhost

A command to forward the port 80 on 192.168.77.15 to localhost:8080 via the foo.example.com SSH server would be:

ssh -L 8080:192.168.77.15:80 -C foo.example.com

The argument to -L specifies the local port, and the destination address and port. The -C argument enables compression, so you again can achieve bandwidth savings, and finally at the end you simply type the SSH host name. This command will open a plain SSH shell session to the host, and in addition to that, listen on localhost port 8080, to which you can connect.

One of the most impressive tricks SSH has developed in recent years is its ability to create real VPN tunnels. These manifest themselves as virtual network devices on both sides of the connection (assuming they have appropriate IP addresses set up) and can allow you access to the remote network as if you were physically there (bypassing firewalls). For both technical and security reasons, this requires root access on both machines which are being connected with the tunnel, so it’s much less convenient than just using port forwarding or SSHFS or SCP. This one is for the advanced users out there, who can readily find tutorials on how to do it.

Remote Office Anywhere

You can continue to work even while you wait for your car at the mechanic.

You can continue to work even while you wait for your car at the mechanic.

Stripped of the need to work from a single location, you can work literally from anywhere that has half-decent Internet connectivity using the technologies and techniques I’ve outlined (including while waiting for your car at the mechanic). Mount foreign systems over SSH, forward ports, drill tunnels, to access your private server or cloud-based data remotely, while overlooking a sun-bathed beach, or drinking hipster-grade eco-friendly coffee in a foggy city. Just do it!
