Hot on the heels of Fedora's release last week comes a Beta release of Red Hat Enterprise Linux.  The new release comes with updates to user authentication via LDAP, Kerberos and FreeOTP as well as Security Content Automation Protocol Security Guides which are standards intended to make compliance and security testing easier.  OpenLMI is a standardized remote API for configuring Linux severs and will be very welcome for those who have to manage servers remotely and may be one of the most heavily tested of the new features on this OS.  Lastly, The Register notes that this version brings little-endian support when running on Power8 hardware which will make porting applications far less of a nightmare than it currently is.

Free hat! The Clouds are opening up, time to put on Fedora 21

Subject: General Tech | December 10, 2014 - 12:40 PM |
Tagged: linux, Fedora, Fedora 21, cloud

Fedora 21 has been released in three different flavours, each intended for a different usage scenario.  The Server version is designed for exactly what it sounds like while the new Cloud version has a modular kernel which is more friendly for being run on remote hardware and is likely to show up in Microsoft Azure's choice of image in their IaaS interface.  The Workstation version is the one that was examined at Linux.com and is likely to be the most common version installed by users.  Fedora has always been a choice for the brave as they tend to be on the cutting edge and while that does mean that they offer features unavailable on other flavours of Linux there can be the occasional bug or other obstacles.  Linux.com found only two so far, Nautilus aka Files stopped working and needed to be either reinstalled or preferably replaced with a better file manager.  The other was an unclear GUI during the updated installation process which is easily avoided once you have seen the screen more than once.  The positives far outnumber the negatives, this looks to be a great improvement on a solid OS and one which should retain its popularity with the software development crowd.  Read the article for the full list of included software and improvements.

If you thought the free Windows programs were contentious, try the Linux version

Subject: General Tech | December 4, 2014 - 01:06 PM |
Tagged: linux, freeware, vim

Nothing brings out the ire of a tech than a list which leaves out their favourite free application or even worse, recommends a lesser alternative.  This goes more than double for Linux users.  Nevertheless,  The Register was brave enough to compile 10 of their favourite Linux applications for your pleasure or derision.  ClamTK is the front end to ClamAV which has been a long standing antivirus program for Linux and Gufw Firewall is fairly self explanatory.  For programmers Geany is a very light weight multipurpose IDE, Shutter does the trick as a screen capture program while Unity Tweak Tool is great for those who want to have complete control over their UI.  LibreOffice does indeed appear on this list and is also available for Windows users but SpringSeed is Linux only and will make Evernote users very jealous.  The full list of apps can be seen here, those wanting an editor battle royale may be dissapointed though.

"Much to the dismay of many a sysadmin, Linux is no longer purely the domain of Captain Command-Line and his trusty side-kick Admiral APT. For those looking to make the most of their new-fangled graphics-capable hardware, here’s a selection of freeware to start with, in our case as installed on Ubuntu 14.04."

Comparing Apples to Unicorns

Subject: General Tech | November 25, 2014 - 12:19 PM |
Tagged: osx, ubuntu 14.10, linux, apple, OS

Over at Phoronix you can see a comparison between the new Apple OS X 10.10 and the newest release of Ubuntu 14.10.  This offers an interesting comparison in performance as both OSes were tested on the same system, a 2013 Macbook Air with a Haswell i5-4250U with onboard HD 5000, 4GB of DDR3-1600MHz and the Apple branded SSD.  For content creators and those with no interest in running Windows it highlights the contrasts you can expect between the two operating systems in data transfer and graphics applications.  Right from the start you can see that the contest is somewhat one sided, the first benchmark, PostMark, showed the disk with Ubuntu installed performing three times as fast as with OSX.  The results get a little closer in some benchmarks but overall Linux outpaces OSX significantly.

"While I delivered some OS X 10.10 Yosemite preview benchmarks back in August, here's my first tests of the official release of Apple OS X 10.10.1 compared to Ubuntu 14.10 Linux. Tests were done of OS X 10.9.5 and OS X 10.10.1 against Ubuntu 14.10 Utopic Unicorn when running the benchmarks under both GCC and LLVM Clang compilers."

SSDs, Linux and alternate file systems

Subject: Storage | November 14, 2014 - 02:00 PM |
Tagged: btrfs, EXT4, XFS, F2FS, 530 series, Intel, raid, unix humour, linux

When you use Linux you have a choice as to which file system you wish to use, a choice that never occurs to most Windows users but can spark an argument every bit as vicious as the eternal debate over EMACS versus VIM versus whichever text editor you prefer.  There has not been much SSD benchmarking done on alternate files systems until now, Phoronix has benchmarked the Intel 530 series SSD in numerous configurations on Btrfs, EXT4, XFS, and F2FS. With four of the 120GB model available they were able to test the speed of the drives in RAID 0, 1, 5, 6, and 1+0.  There is obviously still some compatibility issues as some tests failed to run in certain configurations but overall these drives performed as expected.  While the results did not vary widely it is worth reading through their article if you plan on building a high speed storage machine which will run Linux.

"Following the recent Btrfs RAID: Native vs. Mdadm comparison, the dual-HDD Btrfs RAID benchmarks, and four-SSD RAID 0/1/5/6/10 Btrfs benchmarks are RAID Linux benchmarks on these four Intel SATA 3.0 solid state drives using other file-systems -- including EXT4, XFS, and Btrfs with Linux 3.18."

CS:GO and TF2 on Linux and Radeon

Subject: General Tech | November 12, 2014 - 05:10 PM |
Tagged: linux, amd, radeon, CS:GO, tf2

With the new driver from AMD and a long list of cards to test, from an R9290 all the way back to an HD4650, Phoronix has put together a rather definitive list of the current performance you can expect from CS:GO and TF2.  CS:GO was tested at 2560x1600 and showed many performance changes from the previous driver, including some great news for 290 owners.  TF2 was tested at the same resolution and many of the GPUs were capable of providing 60FPS or higher, again with the 290 taking the lead.  Phoronix also did testing on the efficiency of these cards, detailing the number of frames per second, per watt used, this may not be pertinent to many users but does offer an interesting look at the efficiency of the GPUs.  If you are gaming on a Radeon on Linux now is a good time to upgrade your drivers and associated programs.

"The latest massive set of Linux test data we have to share with Linux gamers and enthusiasts is a look at Counter-Strike: Global Offensive and Team Fortress 2 when using the very newest open-source Radeon graphics driver code. The very latest open-source Radeon driver code tested with these popular Valve Linux games were the Linux 3.18 Git kernel, Mesa 10.4-devel, LLVM 3.6 SVN, and xf86-video-ati 7.5.99."

AMD will be cracking the Linux Catalyst wide open over the next year

Subject: General Tech | October 8, 2014 - 12:28 PM |
Tagged: amd, linux, unified driver, pirate islands

AMD had some news at the 2014 X.Org Developer's Conference that concerns their strategy when it comes to providing open source drivers for Linux.  To start off with the bad news, the new unified driver was prototyped on a not yet released Linux kernel and Sea Islands GPUs and will only work on the next generation of graphics cards, the Pirate Islands.  That is not a terrible thing as backwards compatibility can be a Kong sized monkey on the back of a driver and a fresh start allows the incorporation of features that might be skipped if legacy support is a main focus.  Only a small portion of the driver blob will be proprietary, the majority will be based on Catalyst but will be fully open source and editable.  This means users of the X.Org Server or even just those playing with new versions of the Linux kernel will no longer have to wait for a new Catalyst to be released nor will those playing with OpenGL.  Dive in deeper at Phoronix.

"Alex Deucher of AMD has taken the floor at XDC2014, which got underway today in France to provide an update on the company's new unified open-source driver strategy. Compared to what I originally reported earlier in the year when breaking the news, there's some notable changes but overall this is an exciting endeavor for AMD Linux customers with the open and closed source AMD GPU drivers going to share the same (open-source) Linux kernel driver."

Linux loves Haswell-E

Tagged: linux, X99, core i7-5960x, Haswell-E

After the smoke from their previous attempt at testing the i7 5960X CPU Phoronix picked up a Gigabyte X99-UD4-CF and have now had a chance to test Haswell-E performance on Linux.  The new processor is compared to over a dozen others on machines running Ubuntu and really showed up the competition on benchmarks that took advantage of the 8 cores.  Single threaded applications that depended on a higher clock speed proved to be a weakness as the 4790K's higher frequency allowed it to outperform the new Haswell-E processor.  Check out the very impressive results of Phoronix's testing right here.

"With the X99 burned-up motherboard problem of last week appearing to be behind us with no further issues when using a completely different X99 motherboard, here's the first extensive look at the Core i7 5960X Haswell-E processor running on Ubuntu Linux."

The highs and lows of doing motherboard reviews

Subject: Motherboards | September 11, 2014 - 04:50 PM |
Tagged: magic smoke, linux, Intel X99, MSI X99S SLI Plus

It is inevitable that one will eventually come across hardware with a defect, either a flaw during its manufacture or because of shipping or user damage and when you do reviews the increased sample size pits the odds against you.  This is why Phoronix has not been able to publish results of the i7 5960X on an MSI X99S SLI Plus motherboard as magic smoke was released upon initial boot up.  The board has been RMA'd to NewEgg and MSI has contacted Phoronix directly to let them know they will be sending it off for analysis; a new motherboard and review should be up shortly.  It just goes to show you that this sort of thing can happen to anyone but if you keep your temper in check all it is is a small hurdle not a huge obstruction and you will get to where you wanted to go eventually.  Similar events involving mysterious smells and old UPSes have never occurred here at PC Perspective; especially not today.
