Reddit: Rite of Passage? My first step into linux

Tuesday 7th of March 2017 02:01:10 AM

I have broken my first linux device within hours of booting it up. Running Raspian lite (CLI only) on a humble little pi 2b. This isn't a troubleshooting help question, that isn't my reason for posting. Even though i broke it to hell i am just actually excited to keep playing with it until i get a better handle on the system.

For the curious, i am pretty certain i screwed my sudoers file into oblivion when trying to get my user account sudo privelages. I used the visudo command to get in and edit it and it is adamantly denying any sudo commands pitched at it from all accounts. No big deal. Gunna spend some time trying to fix it if not burn it and start over.

This isn't a story of defeat. Just my first bold step into the unknown. Carry on!

Reddit: What software made you think, "wow, how come I didn't know about this sooner?"

Tuesday 7th of March 2017 12:56:08 AM

I keep finding new things that make me think that. Lately I've been playing with M4. I was wanting a way to use C-style macros in other languages and even tried implementing it native to whatever language I was using. M4 already does what I wanted, and does it well.

I found that it's also useful for standard text processing a la sed, tr, awk etc.. You can do stuff like set a macro name to a single character and replace it with whatever text you want, evaluate math expressions inside it, save your settings to scripts, and a lot more. The learning curve has not been steep either.

I feel like there's probably a lot of stuff I'm missing out on that will make my life a lot easier.

TuxMachines: Best Linux distros

Tuesday 7th of March 2017 12:24:07 AM

While it may not be as popular as Windows or MacOS, Linux is often the operating system of choice for those in the know. A combination of power and versatility has made Linux a firm favourite among developers and self-professed tech geeks over the years.

Contrary to popular belief, however, you don't need to be a programmer or a lifelong tech head to start using Linux. Most of the more popular distros are exceedingly easy to use, with heaps of documentation and guides available online. Best of all, Linux is classed as 'open source' software, meaning that it's completely free!

Reddit: How did we let open source printing support get so poor?

Tuesday 7th of March 2017 12:23:58 AM

I've recently had my Samsung ML-1865W printer stop working and went shopping for a replacement. I was almost settled on a Brother HL-L2340DW when I realized it required closed source drivers installed from sketchy binaries. So I kept researching and realized there don't seem to be any reasonable cheap laser printers with open-source support anymore. Plenty of people rave about the Brother/HP support but both require binaries you have no reason to trust and probably restrict you to x86. I had no idea it had gotten this bad.

Reddit: I've got VLC playing a DVD in tty using ascii text. Anyone know how to get hotkeys to work?

Tuesday 7th of March 2017 12:11:21 AM
vlc --global-key-nav-activate=Enter --global-key-nav-up=w --global-key-nav-down=s --global-key-nav-left=a --global-key-nav-right=d --global-key-play-pause=Space --global-key-quit=Escape --global-key-position=i --global-key-jump-short=Left --global-key-jump+short=Right --global-key-vol-up=Shift+Up --global-key-vol-down=Shift+Down --global-key-vol-mute=Shift+/ dvd:///dev/dvd

This is what I've tried so far. The keys work (except Escape key) in a terminal emulator, but not in tty. Ascii video works just fine with DVDs that automatically play. But once this script runs in tty environment, I'm stuck until I use htop to kill VLC processes. I've also tried them with quotes and used xav to map the keys just to be sure. I'm running a personal distro that I've made with susestudio (OpenSUSE 13.2 32-bit), and I'm working on a CLI menu for the next release for the diehard command line fans.

Phoronix: Core i7 6800K Linux CPU Scaling Benchmarks With Ubuntu 16.10

Monday 6th of March 2017 11:32:19 PM
Earlier today I posted some Linux game CPU scaling benchmarks using a Core i7 6800K Broadwell-E For showing how current Linux games make use of (or not) multiple CPU cores, which originated from discussions by Linux gamers following the AMD Ryzen CPU launch with how many cores are really needed. While going through the process of running those Linux game CPU scaling benchmarks, I also ran some other workloads for those curious...

Minimal Linux Live

Minimal Linux Live is, as the name suggests, a very minimal Linux distribution which can be run live from a CD, DVD or USB thumb drive. One of the things which set Minimal Linux Live (MLL) apart from other distributions is that, while the distribution is available through a 7MB ISO file download, the project is designed to be built from source code using a shell script. The idea is that we can download scripts that will build MLL on an existing Linux distribution. Assuming we have the proper compiler tools on our current distribution, simply running a single shell script and waiting a while will produce a bootable ISO featuring the MLL operating system. Yet another option the MLL project gives us is running the distribution inside a web browser using a JavaScript virtual machine. The browser-based virtual machine running MLL can be found on the project's website, under the Emulator tab. This gives us a chance to try out the operating system in our web browser without installing or building anything. I decided to try the MLL build process to see if it would work and how long it would take if everything went smoothly. I also wanted to find out just how much functionality such a small distribution could offer. The project's documentation mostly covers building MLL on Ubuntu and Linux Mint and so I decided to build MLL on a copy of Ubuntu 16.04 I had running in a virtual machine. The steps to build MLL are fairly straight forward. On Ubuntu, we first install six packages to make sure we have all the required dependencies. Then we download an archive containing MLL's build scripts. Then we unpack the archive and run the build script. We just need to type four commands in Ubuntu's virtual terminal to kick-start the build process. Read more
