I actually now track my reading using Kanban. Books I've decided to read go in to Pending. When I actively start reading one it moves into In Progress and when I complete it it moves into Done. I limit my actively being read books dow

Your Ansible problem is hit when you're setting up a new machine and your live production code is still running on your old production machine. You fix your Ansible script to include the missing dependency, run it against the new serv

You can create an Ansible play that will make sure that only a fixed set of packages are installed. You can even make it pull that list of packages and their versions from another machine (actually very useful for making sure that your prod

> The point is to only maintain the list of packages via this list. Except you'll find that if you have more than one person looking after the machine, someone will install a package directly and it'll get removed by the next p

This looks to me like a script that will shoot you in the foot at some point by removing a package that you've forgotten to put in the configuration list. If you're going to the effort to define the list of packages you want insta

I've used Graphviz for a long time and is still my first port of call where I need to produce the graph as a SVG or PNG. However, if I'm putting the graph into a project in GitHub/GitLab then I'll use Mermaid as it lets

They do gain some data security as they've effectively sharded their database by user. So at the point of a power failure only the active users' data would be at risk of corruption at the file level. Of course there's always

First of all don't beat yourself up over past choices, especially ones like this where you have no idea how things would have turned out if you'd acted differently (I know it's easy to say and hard to do). Should you seek pro

I read Damian's Perl Best Practices book for insights into ways to improve my Perl coding, but since then I've found that the principles I picked up from it have significant improved my code in most other languages as well.

I'm pretty certain that the systems of today have the same foundations as those of yesterday, we've just abstracted them away so we don't directly see it as often.

Code can be written in all programming languages that is hard for other programmers to understand (including the original programmer a few weeks later). I find that Test Driven Development helps to tackle that issue as you get a set of test

If you have a small set of really important data to protect that doesn't change regularly then you can always make it EMP proof by printing it out.

A Faraday Cage should give some protection from an EMP - you could probably build a good one for very little money. There would certainly be differences between HDD and SSD, which I'll be interested to hear about. Depending on the size

Does anyone have any examples of where SELinux saved the day? I appreciate that some of the time you'd never know, but I am curious if anyone has any real life examples where it stopped an attacker.

Sysadmin Rule #1 - Is it SELinux? Sysadmin Rule #2 - Is it systemd? Sysadmin Rule #3 - Have you checked the logs?

by scrapheap 4y ago
In my experience creating and applying new policies with audit2allow is almost always the wrong thing to do. Most SELinux issues are either a SELinux boolean that needs enabling, or SELinux file type that needs changing. The few times wher

I really enjoyed Stephenson's early works, but his later works I've read have all felt like they needed a bit more editing. Don't get me wrong, they're good, but would have really benefited from cutting some of the fille

The ease of use of Subversion is down to it being a centralized version control, which is pretty easy to understand. Switching to a distributed version control like Git takes quite a bit of effort (which I believe is worth it for more comp

Secure Erase is a very good method of erasing drives. However, this article wasn't looking at how to erase the content of the drive, it was looking at how to fill a drive/partition with randomness in preparation for using an encry

First bit of advice, you're so close to graduation make sure you stick with it and graduate - finishing your course shows that you can learn and that you see things through. Once you've graduated don't let the fact that your

One thing I don't like about using `SELECT *` in code is that it hides information from the your future self. When I come back to a piece of code in a couple of years time, knowing which columns I'm selecting helps provide contex
