TuxMachines: Preview: Benchmarking CentOS 7.0 & Scientific Linux 7.0

Thursday 10th of July 2014 05:53:08 PM

In this article just for putting the initial CentOS/SL results into some perspective, I have some initial data from a single Intel Core i7 system running these new releases plus Fedora and Ubuntu Linux. Just as some initial metrics to get started with our benchmarking, from an Intel Core i7 4770K system with 8GB of RAM, 150GB Western Digital VelociRaptor HDD, and Intel HD Graphics 4600, I tested the four Linux distributions. The hardware and its settings were maintained the same during testing.

Originally for this first article I also hoped to test Scientific Linux / CentOS 6.5 too, but after doing the 7.0 tests and trying to boot the 6.5 releases, there was a kernel error preventing the testing from being realized (on initial boot was the i915 DRM error about detecting more than eight display outputs; when booting without DRM/KMS mode-setting support, there would be an agpgart error.) The i915 issue is corrected on future kernel revisions but for this system it was preventing the 6.5 releases from running nicely. From an older, more workstation focused system I will be running the new vs. old CentOS/SL releases.

Reddit: Who the hell is responsible for the dependencies in linux mint 17? I've just deinstalled alsa and pulseaudio, which also deinstalled 70% of my entire system. I've had to download more than 800MB to get everything back to the way it was.

Thursday 10th of July 2014 05:48:12 PM

A simple "sudo apt-get remove --purge alsa pulseaudio" basically deleted half the system.

I can only imagine what were to happen to the guy if this was arch instead of mint.

The packages I've had to reinstall included goodies like mysql and oxygen-cursors. Can anybody explain to me how the fuck these are dependencies for alsa or pulseaudio?

TuxMachines: LXLE 14.04 review – new paradigms

Thursday 10th of July 2014 05:46:02 PM

LXLE has been kicking around for a while now and, for a supposedly lightweight distro, it’s looking fearsomely feature-packed right now. Having said that, it’s hard not to love LXLE, as it’s treading the line between resource efficiency and usability pretty well, and is borderline addictive when it comes to the DE itself. The clue’s in the updated acronym; rather than standing for ‘Lubuntu eXtra Life Extension’, as it did in the days before Lubuntu LTS releases, when LXLE was around to fill that niche using the LXDE desktop environment, it’s now pitched as the ‘LXDE eXtra Luxury Edition’.

TuxMachines: Samsung Nixes Knox: The Android Security Saga Continues

Thursday 10th of July 2014 05:42:05 PM

Granted, Google has been updating handset issues at a quicker pace – particularly when it comes to security patches, via Play Services –and so far, the telcos have not played spoilers. But remember: Google has not initiated a move to push an entirely new OS directly to users except to those who own Google’s telco independent Nexus brand devices. Keep in mind that there’s a big difference between updating a feature or security patch and producing an entirely new OS. OS updates typically up the Kernel and the radios. It will be interesting (and historical) if the telcos continue to stay out of the way.

Reddit: Latest Ubuntu or Latest Mint?

Thursday 10th of July 2014 04:05:51 PM

Hi,

I'm looking for thoughts over which distro and desktop to use next.

I've used Ubuntu since it came out. I've also used Mint "lately" over the last two - three versions.

I'm thinking of going back to Ubuntu, then installing Mate or Cinnamon afterwards.

Which distro do you think will give me a better Mate or Cinnamon experience?

Is there any difference between the two distros, anymore, in terms of getting the multimedia stuff easily set up?

Will I have an easier time installing from an Ubuntu live cd or download the installer?

Any other positive points or gotchas about the latest of either distro I should consider?

Thanks for all opinions

Steve

Reddit: I need to connect my phone to linux

Thursday 10th of July 2014 03:51:09 PM

But it burn the connection via usb. So now with "WiFi File Transfer" program for android (but maybe you know a better system), I'm able to transform the connection to device in http://192.168.1.6:1234/storage.

Is there a method to write this address in /dev/sdb so it appear to be an usb device and I can operate via command line with it?

Or maybe similar ways obviously, I take that example just to give an idea, hope I explain me well! :D

LXer: How to simulate key press and mouse movement in Linux

Thursday 10th of July 2014 03:26:54 PM
Have you ever dreamed of your computer doing stuff automatically for you? Probably not if you just watched Terminator. But except for that, scripting and task automation are every power user's dreams. If a lot of solutions exist today to fit such goal, it is sometimes hard to pick the simple, smart, and efficient one […]Continue reading...The post How to simulate key press and mouse movement in Linux appeared first on Xmodulo.Related FAQs:How to take a screenshot while desktop menu is open on Ubuntu

Reddit: Anyone using centos 7 as a desktop? How do you get video codecs to work?

Thursday 10th of July 2014 03:20:48 PM

First off, I'm really liking it. Like really really liking it. The gnome classical theme is a nice balance between modern and traditional. Plus, somehow it feels a bit snappier than fedora does. However I haven't yet figured out how to get video codecs. rpmfusion doesn't yet have a rhel 7 repo yet.

Anyone know how to get gstreamer plugins? I know I can just use fedora 19 repos but I'm not quiet sure if that's the best idea.

Any help would be nice!

Reddit: This subreddit needs to decide what it wants to be.

Thursday 10th of July 2014 03:12:30 PM

This subreddit is one of the things I enjoy usually during my morning coffee, but lately I'm getting real tired of how much non-related and non-relevant the content has become. Why do we keep allowing these noob questions that are often barely related to Linux/OSS, and almost always so common and googleable that I find myself wondering if people are really so stupid, or just plain lazy? To demonstrate, I made an, admittedly snarky, categorization of the current top 25 posts that I think shouldn't belong here:

Generic-distro-question:

Which Linux Distribution suits me best to increase technical skills (self.linux)

So - which distribution should I use? (self.linux)

Not familiar with Linux, is there just a generic build? (self.linux)

Support / Googling-is-hard:

Btrfs on RAID6? (self.linux)

Which graphics card should I buy? (self.linux)

Any benefit using a Xeon E3 instead of a i7 CPU? (self.linux)

Anyone got a Sony Vaio Pro 13? (self.linux)

Kernel headers (self.linux)

Please-not-this-rehashed-shit-again:

A tiling window-manager setup with eye-candy? (self.linux)

What steps must I take to become a Linux administrator? (self.linux)

Seriously?

Arch Linux - News: BBS, Wiki, and AUR maintenance (archlinux.org)

That's 11 out of 25. Almost half the page is just pure repetitive shit. I'd like to see some stricter rules applied here, and I hope other frequent readers support this also. In particular the 'I do this with a computer, what distro should I use?' drivel is getting real old. There's literally a million blog posts on the internet on this topic.

Slashdot: Prof. Andy Tanenbaum Retires From Vrije University

Thursday 10th of July 2014 02:49:00 PM
When Linus Torvalds first announced his new operating system project ("just a hobby, won't be big and professional like gnu"), he aimed the announcement at users of Minix for a good reason: Minix (you can download the latest from the Minix home page) was the kind of OS that tinkerers could afford to look at, and it was intended as an educational tool. Minix's creator, Professor Andrew Stuart "Andy" Tanenbaum, described his academic-oriented microkernel OS as a hobby, too, in the now-famous online discussion with Linus and others. New submitter Thijssss (655388) writes with word that Tanenbaum, whose educational endeavors led indirectly to the birth of Linux, is finally retiring. "He has been at the Vrije Universiteit for 43 years, but everything must eventually end."

Reddit: Btrfs on RAID6?

Thursday 10th of July 2014 02:38:44 PM

Hey /r/linux,

I had a friend give me a Thecus N5200 Pro. There are several posts online about how you can add a VGA port by soldering it to an existing port on the mainboard, install a new MLC DOM card and install whatever flavor of linux you like. I have done this and am running Ubuntu Trusty on it.

I have 5 x WD Red 3 TB drives setup in a RAID6 array and am ready to decide on the filesystem. Until now, I was going to just use ext4 but did some research and see that many are using other filesystems, such as BTRFS, XFS and ZFS.

I was thinking of going with BTRFS after reading posts about many who have been using it for quite awhile on a RAID array without issue. This would also give me an opportunity to get my hands dirty with BTRFS and learn the ins and outs of it. However, upon checking the BTRFS wiki, I read this:

Parity RAID (RAID 5 and RAID 6) are not currently complete, and have significant problems with recovery from the loss of a device. They should not be used for anything other than testing purposes.

So now I'm unsure. As I mentioned, many seem quite satisfied with the stability of BTRFS, but if the parity bit isn't working correctly, should I stick with ext4 or another filesystem?

Thanks in advance for your thoughts and recommendations!

Reddit: Any benefit using a Xeon E3 instead of a i7 CPU?

Thursday 10th of July 2014 02:37:16 PM

Hello,

I'm an ArchLinux user and I spend a lot of time compiling software by hand, using emulators and virtual machines.

I currently have a i7 3770k but I saw that my motherboard could support at max a Xeon E3-1245 v2.

On the paper theses two processors doesn't look that different, therefore I would like to know more about the benefit of a Xeon over a i7 CPU in my case.

Reddit: So - which distribution should I use?

Thursday 10th of July 2014 02:22:58 PM

Hey guys,

Long time windows user here. I am gonna install a linux distro on my machine, to dual-boot between it and Windows 7. There is no other reason for me than curiousity. I am a software developer, and I wanna know what the fuzz is about. So, which Linux distro would you recommend?

If it's any help as far as my interests this summer goes, then I am probably gonna be working with disassemblers - I'm a bit interested in disassembling malware right now, memory analysis, register analysis - low level things like that. I would probably also try and figure out how I can hack my own server. I will be working exclusively on my laptop.

Thursday 10th of July 2014 01:57:35 PM

Hey all! I'm looking at getting into messing around with Linux and I've noticed that there are lots of distributions geared towards specific concepts (TAILS, Kali, etc.) Is there an all encompassing build?
