DevAssistant can help you set up your development environment, publish your
code, and do many of the chores that somehow keep you from the important
stuff – writing your software. It does not matter if you only recently
discovered the world of software development, or if you have been coding for
two decades, there’s always something DevAssistant can do to make your life
easier.

This is Free Software. Free as in speech. It is released under the
terms of the GPL version 2 or later. That means that you can
do great many things with it freely, but you have to follow some rules too.

libinput

libinput is a library to handle input devices in Wayland compositors and to provide a generic X.Org input driver. It provides device detection, device handling, input device event processing and abstraction so minimize the amount of custom input code compositors need to provide the common set of functionality that users expect.

Runs Linux

Running Debian on a Graphing Calculator

Thx to: Mikerr89 and sorry to bluphenix316!

The newer TI-Nspire series of graphing calculators uses modern ARM devices. [Codinghobbit] managed to get Debian Linux running on a TI-Nspire calculator, and has written a guide explaining how it’s done.

The process uses Ndless, a jailbreak which allows code to run at a low level on the device. Ndless also includes a full SDK, emulator, and debugger for developing apps. In this case, Ndless is used to load the Linux kernel.

Did I just invent “Cloudtop” computing? Here is Ubuntu MATE 14.04 running in a…

dcfldd

dcfldd is an enhanced version of GNU dd with features useful for forensics and security.
Based on the dd program found in the GNU Coreutils
package, dcfldd has the following additional features:

Hashing on-the-fly – dcfldd can hash the input data as it is being transferred,
helping to ensure data integrity.
Status output – dcfldd can update the user of its progress in terms of the
amount of data transferred and how much longer operation will take.
Flexible disk wipes – dcfldd can be used to wipe disks quickly and with a known
pattern if desired.
Image/wipe Verify – dcfldd can verify that a target drive is a bit-for-bit match of the specified input file or pattern.
Multiple outputs – dcfldd can output to multiple files or disks at the same time.
Split output – dcfldd can split output to multiple files with more configurability than the split command.
Piped output and logs – dcfldd can send all its log data and output to commands as well as files natively.

Announcing Snappy Ubuntu

Guest: Dustin Kirkland (@dustinkirkland)

A new, transactionally updated Ubuntu for the cloud.

Ubuntu Core is a new rendition of Ubuntu for the cloud with transactional updates. Ubuntu Core is a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users — that’s why we call them “snappy” applications.

Snappy apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed — a bulletproof approach to systems management that is perfect for container deployments. It’s called “transactional” or “image-based” systems management, and we’re delighted to make it available on every Ubuntu certified cloud.

Mark Shuttleworth » Blog Archive » Announcing Ubuntu Core, with snappy transactional updates!

What if your cloud instances could be updated with the same certainty and precision as your mobile phone — with carrier grade assurance that an update applies perfectly or is not applied at all? What if your apps could be isolated from one another completely, so there’s no possibility that installing one app could break another, and stronger assurance that a compromise of one app won’t compromise the data from another? When we set out to build the Ubuntu Phone we took on the challenge of raising the bar for reliability and security in the mobile market. And today that same technology is coming to the cloud, in the form of a new “snappy” image called Ubuntu Core, which is in beta today on Azure and as a KVM image you can run on any Linux machine.

Yahoo Starts Prompting Chrome Users To “Upgrade” To Firefox

If you’re visiting any Yahoo property today, chances are you’ll see an “Upgrade to the new Firefox” link in the top-right corner of your browser window. The prompt also appears if you’re using Internet Explorer, Opera and even the new Yandex browser. However, the prompt is missing from Safari, which will surely prompt a new round of speculation about Apple’s rumored switch to Yahoo as its default search engine.
