Necessity is the mother of invention, but sometimes frustration is as good a motivator. [Maciej] does a bunch of statistics in his day job using SPSS. Like most complicated pieces of software, it can get hung, and the only way to stop it is to manually kill the running processes. Apparently, that happened one time too many for [Maciej].
He took matters into his own hands, repurposing a big red emergency-stop button for the task. It’s mounted on a jar, and the microcontroller inside is configured as a USB keyboard. When he mashes the button, it opens the “Run…” menu and types out
taskkill spssengine.exe for him.
We can totally see the therapeutic value of such a device. Plus, in case SPSS is gobbling up his system memory and everything’s approaching standstill, the vital seconds saved by the microcontroller’s quick-typing fingers could be a lifesaver.
[Geekmaster] wrote in to tell us about a new hack for the Amazon Kindle. It’s a jailbreak. A Universal jailbreak for almost every eInk Kindle eReader eOut eThere.
This jailbreak is a pure software jailbreak for the Kindle Paperwhite 2, the Kindle Paperwhite 3, Kindle Touch, Kindle Voyage, and Kindle Oasis. If you’re keeping track, that’s any 6th, 7th, or 8th generation device, running any firmware version. Already the jailbreak has been tested by over one thousand people, after the cloud served up half a Terabyte of jailbreak image downloads. That’s extraordinarily popular for a device that hasn’t seen much action of late.
Several years ago, [Geekmaster] made a name for himself – and for [NiLuJe], [KNC1], and other developers over at the Mobileread forums – for jailbreaking the Kindle Paperwhite. This jailbreak was, and is extremely simple; just upload a file to the root directory, restart, and the Kindle is jailbroken. The latest development extends this to nearly all Kindle models, while still being as easy to deploy as the original hack from four years ago.
If you’re looking for something to do with a neat jailbroken device with an eInk screen, they make a great serial console, thermostat, and wallpaper.
