Phoronix: Broadwell Linux Ultrabook Running MUCH Cooler Than Haswell

Sunday 25th of January 2015 07:44:51 PM
Aside from the performance benefits of Broadwell, particularly in having greater graphics capabilities, laptops and ultrabook designs are much more power efficient than former Haswell products. Here's some quick tests I did today comparing the Broadwell-based Core i7 ThinkPad X1 Carbon to my former Haswell-based Core i7 ASUS Zenbook ultrabook...

Reddit: Filesystem difference to installable packages

Sunday 25th of January 2015 04:48:16 PM

Is there a tool that does the following:

  • Take a freshly installed system
  • Create "snapshot"
  • Do modifications
  • Create "snapshot"
  • Turns the difference between the "clean" snapshot and the "modified" snapshot in to an installable DEB/RPM package?

Reddit: Laptop recommendation as of 2015?

Sunday 25th of January 2015 04:31:27 PM

Hi there,

Most of these threads I've come across are over a year old, so I was hoping to get an updated perspective, especially with that new round of thinkpads seemingly disappointing a lot of people (trackpad is garbage, rumors of issues with newer dual band intel wireless chips, etc..).

I currently have a T420, which is a fantastic linux machine, but since then I've moved to Gentoo as the daily driver and am doing a lot of compiled development for work. I'm looking for excellent linux support out-of-the-box, a fast wireless chip, decent trackpad, newer-gen i7, and a price-tag that doesn't break the bank (ideally < $800). I have a couple SSDs and some laptop memory already, so I could save a few bucks there since I can replace a mechanical drive.

I was looking at a lenovo E540, but the trackpad and wireless chip are scaring me away. I also couldn't care less about touchscreen.

What do you guys think?

Slashdot: Ask Slashdot: GPU of Choice For OpenCL On Linux?

Sunday 25th of January 2015 03:38:00 PM
Bram Stolk writes So, I am running GNU/Linux on a modern Haswell CPU, with an old Radeon HD5xxx from 2009. I'm pretty happy with the open source Gallium driver for 3D acceleration. But now I want to do some GPGPU development using OpenCL on this box, and the old GPU will no longer cut it. What do my fellow technophiles from Slashdot recommend as a replacement GPU? Go NVIDIA, go AMD, or just use the integrated Intel GPU instead? Bonus points for open sourced solutions. Performance not really important, but OpenCL driver maturity is.

Reddit: Help with streaming graphical applications or opengl 3/4 drivers

Sunday 25th of January 2015 03:09:09 PM


Me and a friend are developing a game, but his laptop broke and he doesn't have any money to repair it. We want to continue working, so he's working on an older computer with an integrated graphics card, and glxinfo tells me the opengl version is 1.4.

Since we use OpenGL shaders, this is way too old to be usable.

So my question is if there is either a way to install OpenGL version 3.0/4.0 driver for the integrated graphics card (lspci says it's a Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)), or if he can run the game on my computer and have it stream to his computer so he can test it and work on it. (it shouldn't involve taking control of my whole computer, since I need to work on it at the same time).

LXer: Netrunner 14.1 Screenshot Tour

Sunday 25th of January 2015 02:15:43 PM
This is the release announcement of Netrunner 14.1 Main edition 'Frontier'. The '14.1' indicates an updated and polished release of Netrunner 14 LTS on the same underlying base. Since 14.1 is using the same 'Trusty' base as Netrunner 14, there is no need for users of 14 to migrate; simply updating from the shared backports ppa of the Frontier release cycle should give the same result, while keeping customizations in place. So 14.1 is a fresh starting point for new users who want to install an up-to-date KDE 4-based system from the ISO image. This is the first time we are working on both updating our current LTS base (Frontier), while at the same time preparing the next release, Netrunner 15 (Prometheus), with the upcoming KDE Plasma 5.2.

Hello community,

I recently switched from debian to fedora and I did encounter this problem when I want to ssh into my ubuntu server instance hosted by amazon:

ssh: connect to host xxxxxxx port 22: Connection timed out

I am a total newb and I understand that I maybe need to whitelist my servers IP on this machine but I have no clue how to achive this.

Thanks in advance

Phoronix: How To Use GCC 5's OpenMP & OpenACC Offloading Support

Sunday 25th of January 2015 12:26:32 PM
With the upcoming GCC 5 compiler release there is the offloading infrastructure support in place as OpenMP 4.0 and OpenACC compute offloading to accelerators begin to mature in this open-source compiler. For those willing to toy with the latest experimental code, it's possible to get your feet wet if you have a NVIDIA GPU or supported Intel Xeon Phi MIC card...

LXer: Google makes it easier to run Linux on a Chromebook via a USB drive…sort of…

Sunday 25th of January 2015 12:21:21 PM
I wrote a post recently about how Chromebooks were hurting Microsoft, and now Google has made Chromebooks potentially even more appealing by theoretically making it easier for you to run Linux on them. Developer mode in Chrome OS now offers the option of booting from USB, so it might be possible to boot a Linux distro off a USB drive and run it it on your Chromebook.

Reddit: The brightness adjustment seems a bit broken

Sunday 25th of January 2015 11:58:51 AM

Have you come across the problem where the laptop brightness adjustment happens in multiple steps?

Most laptops seem to exhibit this kind of behavior at least under Debian-based distros. It seems that there is multiple listeners to the adjustment event and they all perform the change.

There are some workarounds, but this mess really should be sorted out some day.

Reddit: OSX/copyright

Sunday 25th of January 2015 08:55:02 AM

how close can a desktop environment get to OSX before apple kicks up a fuss.

aside from a long dark period in which mission-control had compulsory app-bundles - I think its' the best 'window-manager' out there now - the way it handles 'expose' with a desktop overview with horizontal arrangement, and the way it handles multiple monitors (independent fullscreen apps and desktop list, ability to drag desktops between them..) .. its' a shame apple got there first. Gnome shell gives me vertigo, and I've gone off unity.

how much of this can be replicated exactly in linux? ( I haven't tried gnome shell or unity lately, I've been using XFWM mostly).

is it possible for an environment to have options to behave exactly like OSX , just not configured by default?

Using a mac laptop, expose is far from a gimmick, because you can read the small print on a retina display. It lets a given physical area of pixels (and hence electricity to illuminate them) punch above its weight.

Embedded Development with ARM mbed on Linux

The ARM CPU used in the BeagleBone Black and other single board computers is designed to interface with half to a few gigabytes of RAM and allow a full operating system such as Linux to be run on the computer. (See my long series of reviews on of ARM-based computers that run Linux). By contrast the ARM Cortex-M is a microcontroller level chip which might run at 16-100Mhz, contain 2-100kb of RAM, and some flash memory to contain only the program that you want to execute.

Confessions of a systems librarian

These are just two examples of serious flagship projects, but even on a day-to-day level there are plenty of opportunities for systems librarians to interact with open source software. A large amount of vendor software runs on Linux, so there’s plenty of systems administration to do. I work in a relatively small library, and even here we run five Drupal websites: one as a portal for library services, one as the primary repository for our archive, another provides the public interface for an aboriginal research center, and one to manage safety information for our bio sciences lab.

IoT, Revolution In Personal Computing, or FLOSS Taking Over the World of IT

What can you say? In a few short years, that other OS has gone from mainstream to niche and Android/Linux and GNU/Linux are stepping up to displace it as the goto OS of the world. It’s all good. This is the right way to do IT with the world making its own software throughout the whole stack: OS on client and server and a ton of applications too. There is no need for a monopoly in IT. The world wants a revolution not lock-in. Read more

Political parties favour openness to reconstruct Greek productivity

Ahead of the parliamentary elections in Greece last week, the Greek Free/Open Source Software Society (GFOSS) contacted all political parties to ask about their positions [in Greek] with regard to open software, open data, open hardware and open government. The four parties to respond all came out generally in favour of openness. Some of them were even able to present very detailed planning on how to improve the current institutional and legislative framework and outlined how openness could help reconstruct Greek productivity.
