Linux is a delightful OS. There are an amazing range of built-in tools, and innumerable others that can be installed from publicly available repositories using just a single line of commands. You can also hose your entire system with just a handful of characters; something that was en vogue as a method of trolling many years ago. Who knows if either of those will get used when Twitch Installs Arch Linux.
Beginning on Saturday morning, a single keyboard will be controlled by thousands of people whose collective goal is to install a Linux distro in a virtual box. There will undoubtedly be thousands of others trying to thwart the process. We were enthralled with Twitch Plays Pokemon last year. Live viewers’ keystrokes were translated to the Game Boy controls and the majority consensus decided the next move. This was insane with just a few controls, but now we’re talking about an entire keyboard.
Every 10 seconds, the most popular keystroke will be chosen. To put this in perspective, the previous sentence would have taken exactly 10 minutes to type, and only if the majority constantly agreed on what the next letter should be. We can’t tell if it’s going to be interesting or boring to participate. But either way, we can’t wait to see what unforeseen happenings shake out of the process.
It’s always nice to get down to the root directory of a device, especially if the device in question is one that you own. It’s no huge surprise that a Google product allows access to the root directory but the OnHub requires locating the hidden “developer mode” switch which [Maximus64] has done. The Google engineers have been sneaky with this button, locating it at the bottom of a threaded screw hole. Has anyone seen this implemented on other hardware before?
There isn’t a blog post regarding this, however [Maximus64] shared a video on YouTube walking us through the steps to root and un-root Google’s OnHub, which is embedded after the break. He also states “wiki coming soon” in the description of the video, so we’ll keep eye on it for an update.
We covered the product announcement back in August and have heard a few reviews/opinions about the device but not enough to make an opinionated assumption. Rooting the device doesn’t seem to increase the OnHub’s number of LAN ports but we think it’s still worth the effort.

We’re surrounded by tiny ARM boards running Linux, and one of the most popular things to do with these tiny yet powerful computers is case modding. We’ve seen Raspberry Pis in Game Boys, old Ataris, and even in books. [Aaron] decided it was time to fit a tiny computer inside an officially licensed bit of miniature Apple hardware and came up with the Mini PowerMac. It’s a 1/3rd scale model of an all-in-one Mac from 1996, and [Aaron] made its new hardware fit like a glove.
Instead of an old Mac modified with an LCD, or even a tiny 3D printed model like Adafruit’s Mini Mac Pi, [Aaron] is using an accessory for American Girl dolls released in 1996. This third-scale model of an all-in-one PowerPC Mac is surprisingly advanced for something that would go in a doll house. When used by American Girl dolls, it has a 3.25″ monochrome LCD that simulates the MacOS responding to mouse clicks and keypresses. If you want to see the stock tiny Mac in action, here’s a video.
The American Girl Mini Macintosh is hollow, and there’s a lot of space in this lump of plastic. [Aaron] tried to fit a Raspberry Pi in the case. A Pi wouldn’t fit. An ODROID-W did, and with a little bit of soldering, [Aaron] had a computer far more powerful than an actual PowerMac 5200. Added to this is a 3.5″ automotive rearview display, carefully mounted to the 1/3rd size screen bezel of the mini Mac.
The rest of the build is exactly what you would expect – a DC/DC step down converter, a USB hub, and a pair of dongles for WiFi and a wireless keyboard. The software for the ODROID-W is fully compatible with the Raspberry Pi, and a quick install of the Basilisk II Macintosh emulator and an installation of Mac OS 7.5.3 completed the build.
Quick, what do “cloud compute engines” and goofy Raspberry Pi Internet of Things hacks have in common? Aside from all being parody-worthy buzzword-fests, they all involve administering remote headless (Linux) installations. It’s for exactly that reason that a new Ubuntu distribution flavor, Ubuntu (Snappy) Core, targets both the multi-bazillion-dollar Amazon Elastic Compute Cloud and the $55 BeagleBone Black.
If that combination seems unlikely to you, you’re not alone. But read on as we hope to make a little more sense of it all.

One of our chief complaints about the Raspberry Pi is it doesn’t have a lot of I/O. There are plenty of add ons, of course to expand the I/O capabilities. The actual Raspberry Pi foundation recently created the Sense Hat which adds a lot of features to a Pi, although they might not be the ones we would have picked. The boards were made for the AstroPi project (the project that allowed UK schools to run experiments in space). They don’t appear to be officially for sale to the public yet, but according to their site, they will be selling them soon. Update: Despite some pages on the Raspberry Pi site saying they aren’t out yet, they apparently are.

When the Raspberry Pi came on the scene it was hard to imagine that you could get a fairly complete Linux system for such a low price. The Pi has gotten bigger, of course, but there are still a few things you miss when you try to put one into a project. Wifi, comes to mind, for example. The first thing you usually do is plug a Wifi dongle in, consuming one of the two USB ports.
The Orange Pi is a direct competitor and has a few variants. Originally, the board cost about $30 but sports WiFi, a 1.6 GHz processor, 8 GB of flash, and a SATA interface. There’s now a reduced version of the board for about $15 that deletes the flash and SATA along with the WiFi and one of the original’s 4 USB ports. Still, the Raspberry Pi doesn’t have built-in flash. And the $15 Orange Pi PC has the things you’d expect on a Pi (HDMI and Ethernet) along with other extras like an IR receiver and an on-board microphone. Not bad for $15 considering it has a quad-core processor, a GPU and 1GB of RAM. Continue reading “Orange is the New ($15) Pi”
[Voltagex] was fed up with BSODs on his Windows machine due to a buggy PL2303 USB/serial device driver. The Linux PL2303 driver worked just fine, though. A weakling would simply reboot into Linux. Instead, [Voltagex] went for the obvious workaround: create a tiny Linux distro in a virtual machine, route the USB device over to the VM where the drivers work, and then Netcat the result back to Windows.
OK, not really obvious, but a cool hack. Using Buildroot, a Linux system cross-compilation tool, he got the size of the VM down to a 32Mb memory footprint which runs comfortably on even a small laptop. And everything you need to replicate the VM is posted up on Github.
Is this a ridiculous workaround? Yes indeed. But when you’ve got a string of tools like that, or you just want an excuse to learn them, why not? And who can pass up a novel use for Netcat?
