The classic rm -rf / is there, along with accidental dd‘ing or mkfs‘ing the wrong disk (I’ve done that before), but the lesser known fork bombs and moving to /dev/null are in there (I often redirect output to /dev/null, but not moved files into there. That’s an interesting way of getting rid of files.
Not often I quote from a publication from Ireland, but this was quite an intriguing read. Someone who went from Windows to Mac to Linux (Mint)
Linux is everywhere – and will free your computer from corporate clutches
It was 2002, I was up against a deadline and a bullying software bubble popped up in Windows every few minutes. Unless I paid to upgrade my virus scanner – now! – terrible things would happen.
We’ve all had that right?
In a moment of clarity I realised that the virus scanner – and its developer’s aggressive business model – was more of a pest than any virus I’d encountered. Microsoft’s operating system was full of this kind of nonsense, so, ignoring snorts of derision from tech friends, I switched to the Apple universe.
It was a great choice: a system that just worked, designed by a team that clearly put a lot of thought into stability and usability. Eventually the iPhone came along, and I was sucked in farther, marvelling at the simple elegance of life on Planet Apple and giving little thought to the consequences.
Then the dream developed cracks. My MacBook is 10 years old and technically fine, particularly since I replaced my knackered old hard drive with a fast new solid-state drive. So why the hourly demands to update my Apple operating system, an insistence that reminded of the Windows virus scanner of old?
Apple is no different to Microsoft it seems.
I don’t want to upgrade. My machine isn’t up to it, and I’m just fine as I am. But, like Microsoft, Apple has ways of making you upgrade. Why? Because, as a listed company, it has quarterly sales targets to meet. And users of older MacBooks like me are fair game.
I looked at the price of a replacement MacBook but laughed at the idea of a midrange laptop giving me small change from €1,200. Two years after I de-Googled my life(iti.ms/2ASlrdY) I began my Apple prison break.
He eventually went for Linux Mint, which for a casual user is fine. I use Fedora and Ubuntu (and a really old version of Ubuntu since my workplace VPN doesn’t seem to work properly with anything above Ubuntu 14 – their way of forcing me onto either a Windows or Mac machine)

Something new I learned today — doing
export TMOUT=120
Will auto logout your current shell/login session after that many seconds.
Very useful if you hook this into the root account’s profile or as a default to all users so people can’t leave terminals open

As someone who has tinkered with multiple distributions, this will be a great way to try out multiples
This tutorial shows you how to install multiple Linux distributions on one USB. This way, you can enjoy more than one live Linux distros on a single USB key.

Torvalds is not a huge fan of the ‘security community’ as he doesn’t see it as black and white. He maintains that bugs are part of the software development process and they cannot be avoided, no matter how hard you try. “constant absolute security does not exist, even if we do a perfect job,” said Torvalds in a conversation with Jim Zemlin, the executive director of the Linux Foundation.
“As a technical person, I’m always very impressed by some of the people who are attacking our code,” Torvalds said. “I get the feeling that these smart people are doing really bad things that I wish they were on our side because they are so smart and they could help us.”

Looking forward to when LineageOS can upgrade to Oreo. There’s a lot of new features that may make life a lot easier generally. Take a look in the article for details

Cyanogen’s fork is beginning to take shape. Currently my devices aren’t showing but fingers crossed it will.
Few points worth noting from their site:
The build roster is ever growing, but we are supporting Marshmallow and Nougat capable devices.
- We’ll list the 80+ devices in a separate post.
Our release cadence will be ‘weekly’ by default (to be nice to all the donated hardware).
We will NOT be shipping root baked into the ROM.
- Root will be a downloadable zip based install similar to gapps installation (only need to flash it once).
- Home builders that want to bake su back into the ROM can use the command ‘export WITH_SU=true’ prior to building.
Our official builds will all be signed with a private key for authentication and signature permission control
This will not break, prevent or stop any ‘unofficial’ builds.
Key verification info can be found on the wiki Verifying Build Authenticity page
However, also notable and I’m really happy about this:
Regarding installation, we recommend that users wipe when switching to LineageOS, and reinstall their gapps. However, we recognize that this can be time consuming, so we are offering an EXPERIMENTAL (read as, if it fails, you’ll have to wipe anyways) solution.
- Alongside the ‘weekly’ release for your supported device, we’ll provide an EXPERIMENTAL data migration build.
- This build will allow you to ‘upgrade’ from CM to the signed LineageOS weekly
- This build may wipe permissions (you’ll have to re-allow app permissions), but should retain all user data
- This build will be watermarked with an ugly banner to ensure that you don’t permanently run this EXPERIMENTAL release, and upgrade to a normal weekly after.
- The process for this installation will be as follows:
- Install EXPERIMENTAL migration build on top of cm-13.0 or cm-14.1 build (don’t try to install LineageOS 13.0 on top of CM 14.1, that will not work).
- Reboot
- Install LineageOS weekly build
- Reboot
- Re-setup your application permissions
Given the EXPERIMENTAL nature of this process, we are going to remove this option in two months time.
All systems operational

Despite being a library that most people outside of the technology industry have never heard of, the Heartbleed bug in OpenSSL caught the attention of the mainstream press when it was uncovered in April 2014 because so many websites were vulnerable to theft of sensitive server and user data. At LinuxCon Europe, Rich Salz and Tim Hudson from the OpenSSL team did a deep dive into what happened with Heartbleed and the steps the OpenSSL team are taking to improve the project.

An attempt to bust some of the myths that surround Linux. Not a lot of them, but still some of them – some of which I see a lot in Windows communities. And the old classic “Linux is CLI only” (facepalm)
