Reddit: Do RHEL developers actually develop or do they just backport security patches?

Monday 4th of August 2014 08:31:13 PM

The development process of RHEL was always a bit of a riddle for me. As far as I understand - RHEL is forked from an older version of Fedora. The RHEL team is responsible for back porting security patches for the packages available in RHEL repositories. Red Hat does seem to have a large group of developers. Are they mostly contributing to open source projects available in RHEL? If so, does that mean that Red Hat pays its developers mostly to help the open source world?

Slashdot: Linux Kernel Shuffling Zombie Juror Aka 3.16 Released

Monday 4th of August 2014 07:17:00 PM
sfcrazy writes Linus Torvalds has announced the release of Linux kernel 3.16 codenamed "Shuffling Zombie Juror", which brings many notable improvements. Linus said, "So while 3.16 looked a bit iffy for a while, things cleared up nicely, and there was no reason to do extra release candidates like I feared just a couple of weeks ago." It also means that working on 3.17 has started, "And as usual (previous release being the exception) that means that the merge window for 3.17 is obviously open," said Linus.

Reddit: Mouse keyboard errors in Ubuntu 14.1 and Mint 17

Monday 4th of August 2014 06:44:35 PM


I've just completed a new build (specs below) and I'm trying to install my OS.

Initially I was going with Mint 17 (Cinnamon), so I burned the ISO onto disc and loaded it up. I problem I'm having is my mouse and keyboard work for only ~10 seconds before they freeze completely. I know it's the mouse because if I disconnect the unified wireless USB thingy and reconnect it again they work before freezing again.

I'm currently using a Logitech mk520 wireless combo but I tried a wired Dell keyboard with a different wireless mouse before and the problem has remained.

PC specs:

Type Item CPU AMD FX-6300 3.5GHz 6-Core Processor CPU Cooler Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler Motherboard Gigabyte GA-970A-UD3P ATX AM3+ Motherboard Memory Kingston HyperX Blu 8GB (2 x 4GB) DDR3-1333 Memory Storage Kingston SSDNow V300 Series 120GB 2.5" Solid State Drive Storage Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive Video Card Sapphire Radeon HD 7790 1GB Video Card Case Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case Power Supply Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply Optical Drive Lite-On iHAS124-04 DVD/CD Writer Wireless Network Adapter TP-Link TL-WN722N 802.11b/g/n USB 2.0 Wi-Fi Adapter

After failing to find a solution for Mint I thought I'd try a different distro and see if that helped. Loaded up Ubuntu 14.1 and the problem persists.

Can anyone advice on what I should try next?

TuxMachines: Xen EFI Support Being Added To Linux 3.17

Monday 4th of August 2014 06:43:24 PM

With the Linux 3.17 kernel that's now officially under development since yesterday's Linux 3.16 release is now support for Xen EFI.

With the upcoming Linux 3.17, it's possible to boot using (U)EFI under Xen Dom0. Daniel Kiper who worked on the Xen EFI patches explained, "Standard EFI Linux Kernel infrastructure cannot be used because it requires direct access to EFI data and code. However, in dom0 case it is not possible because above mentioned EFI stuff is fully owned and controlled by Xen hypervisor. In this case all calls from dom0 to EFI must be requested via special hypercall which in turn executes relevant EFI code in behalf of dom0."

Reddit: Help with Cron - though it's probably not really a cron problem.

Monday 4th of August 2014 04:51:48 PM

I have a script that I am trying to run with Cron. The script is using xdotool to locate an active firefox window and send a ctrl-Tab keystroke to it to switch tabs in the Firefox window. I would like the script to run every three minutes. At the momnent the script is called firefox and is located in my /home/dave folder.

When I run the script from the command line like this ./firefox, it works perfectly. When I attempt to add a line to my crontab and run the script on a schedule it's not working. I am seeing this error in the email generated by Cron,

No protocol specified Error: Can't open display: (null) Failed creating new xdo instance

Currently my script looks like this:

#!/bin/bash export DISPLAY=:0 xdotool search "Mozilla Firefox" windowactivate --sync key --clearmodifiers ctrl+Tab

The line in my crontab currently looks like this:

* * * * * /home/dave/firefox

A previous incarnation of the line in Cron looked like this:

* * * * * env DISPLAY=:0 /home/dave/firefox

That one didn't work either.

I am currently logged into the machine as user dave, the crontab I'm using is for root and this all running in Lubuntu. I'm definitely a little unclear on X sessions and how those pertain to users, but from the errors I'm getting in the mail generated by the cron task, I suspect that that is where the problem lies. Can anyone shed some light on what I might need to do here to get this script to run properly?

Thanks in advance.

Edit: Yes, I understand that presently my Cron script is going to run every minute not every three.

Scrivener Writing Software has a Linux Version

In some ways, Scrivener is the very embodiment of anti-Linux, philosophically. Scrivener is a writing program, used by authors. In Linux, one strings together well developed and intensely tested tools on data streams to produce a result. So, to author a complex project, create files and edit them in a simple text editor, using some markdown. Keep the files organized in the file system and use file names carefully chosen to keep them in order in their respective directories. when it comes time to make project-wide modifications, use grep and sed to process all of the files at once or selected files. Eventually, run the files through LaTeX to produce beautiful output. Then, put the final product in a directory where people can find it on Gopher.

Gopher? Anyway …

On the other hand, emacs is the ultimate linux program. Emacs is a text editor that is so powerful and has so many community-contributed “modes” (like add-ins) that it can be used as a word processor, an email client, a calendar, a PIM, a web browser, an operating system, to make coffee, or to stop that table with the short leg from rocking back and forth. So, in this sense, a piece of software that does everything is also linux, philosophically.

And so, Scrivener, despite what I said above, is in a way the very embodiment of Linux, philosophically.

I’ve been using Scrivener on a Mac for some time now, and a while back I tried it on Linux. Scrivener for the Mac is a commercial product you must pay money for, though it is not expensive, but the Linux version, being highly experimental and probably unsafe, is free. But then again, this is Linux. We eat unsafe experimental free software for breakfast. So much that we usually skip lunch. Because we’re still fixing breakfast. As it were.

Details with Screen Shots Here

Anyway, here’s what Scrivener does. It does everything. The full blown Mac version has more features than the Linux version, but both are feature rich. To me, the most important things are: A document is organised in “scenes” which can be willy nilly moved around in relation to each other in a linear or hierarchical system. The documents are recursive, so a document can hold other documents, and the default is to have only the text in the lower level document as part of the final product (though this is entirely optional). A document can be defined as a “folder” which is really just a document that has a file folder icon representing it to make you feel like it is a folder.

Associated with the project, and with each separate document, is a note taking area. So, you can jot notes project-wide as you work, like “Don’t forget to write the chapter where everyone dies at the end,” or you can write notes on a given document like “Is this where I should use the joke about the slushy in the bathroom at Target?” Each scene also has a number of attributes such as a “label” and a “status” and keywords. I think keywords may not be implemented in the Linux version yet.

Typically a project has one major folder that has all the actual writing distributed among scenes in it, and one or more additional folders in which you put stuff that is not in the product you are working on, but could be, or was but you pulled it out, or that includes research material.

You can work on one scene at a time. Scenes have meta-data and document notes.

The scenes, folders, and everything are all held together with a binder typically displayed on the left side of the Scrivener application window, showing the hierarchy. A number of templates come with the program to create pre-organized binder paradigms, or you can just create one from scratch. You can change the icons on the folders/scenes to remind you of what they are. When a scene is active in the central editing window, you can display an “inspector” on the right side, showing the card (I’ll get to that later) on top the meta data, and the document or project notes. In the Mac version you can create additional meta-data categories.

An individual scene can be displayed in the editing window. Or, scenes can be shown as a collection of scenes in what is known as “Scrivenings mode.” Scrivenings mode is more or less standard word processing mode where all the text is simply there to scroll through, though scene titles may or may not be shown (optional). A lot of people love the corkboard option. I remember when PZ Myers discovered Scrivener he raved about it. The corkboard is a corkboard (as you may have guessed) with 3 x 5 inch virtual index cards, one per scene, that you can move around and organize as though that was going to help you get your thoughts together. The corkboard has the scene title and some notes on what the scene is, which is yet another form of meta-data. I like the corkboard mode, but really, I don’t think it is the most useful features. Come for the corkboard, stay for the binder and the document and project notes!

Community chest: Storage firms need to pay open-source debts

Linux and *BSD have completely changed the storage market. They are the core of so many storage products, allowing startups and established vendors alike to bring new products to the market more rapidly than previously possible. Almost every vendor I talk to these days has built their system on top of these and then there are the number of vendors who are using Samba implementations for their NAS functionality. Sometimes they move on from Samba but almost all version 1 NAS boxen are built on top of it. Read more

Did Red Hat’s CTO Walk – Or Was He Pushed?

He went on to say that some within Red Hat speculate that tensions between Stevens and Paul Cormier, Red Hat’s president of products and technologies, might be responsible, although there doesn’t appear to have been any current argument between the two. Cormier will take over Stevens’ duties until a replacement is found. Vaughan-Nichols also said that others at Red Hat had opined that Stevens might’ve left because he’d risen as high as he could within the company and with no new advancement opportunities open to him, he’d decided to move on. If this was the case, why did he leave so abruptly? Stevens had been at Red Hat for nearly ten years. If he was leaving merely because “I’ve done all I can here and it’s time to seek my fortune elsewhere,” we’d expect him to work out some kind of notice and stay on the job long enough for Red Hat to find a suitable replacement. Turning in a resignation that’s effective immediately is not the ideal way to walk out the door for the last time. It smells of burning bridges. Read more
