Preventing degraded array on every boot

I had a server that booted with a degraded array every time, because there was a USB drive attached to it, that messed up the auto detection. I solved it by putting this in mdadm.conf: Read More »

Master PDF Editor for Linux

While trying to find out the quickest, cleanest way to install PDFedit program in Linux Mint, I stumbled upon Master PDF Editor for Linux, which is basically the same thing, but more advanced and closed source, but free for personal use. Read More »

Multiplication in BULL

Now, what will follow is the first published note about BigSmoke's Unified Linking Language (BULL), posted here not for you but for me, because my notes are such a terrible mess, covering too many pieces of papers and disjointed files. Read More »

Using papercite WordPress plugin for academic note-taking

During most of my bachelor, I've used paper and pen or pencil to take notes. Halfway my second minor [Okasys], though, I switched to my laptop and LaTeX, which I preferred, because typing is faster than writing and reworking my notes into a halfway decent summary usually proved too time-consuming with hand-written notes. Admittedly, though, although reorganizing my notes became easier with LaTeX, I still didn't really get to the finished summary stage, because I'm still way too obsessive-compulsive about the whole thing, most of the time. Now, since I figured I use my blog for all sorts of notes, I can just as well let WordPress and Google do some of the organizing for me, while taking notes for my present course. I just have to be a bit more careful about copyright issues (but, if the need strikes, I can always set a post to private). Read More »

Programming is talking to the future

One day, some day long ago, I said to Jeroen Dekker, a photographer friend of mine, who was still learning to program at the time: “Programming is talking to the future.” He thought it was a good quote. Coming across it again now, so do I. It's good because it's true, which everybody who has ever debugged some old code—be it their own or someone else's—can attest to. Read More »

Installed MathJax-LaTeX WordPress plugin for

Soon, I wish to document some statistical issues I've been running into lately due to the lack of understanding maintained by my recipe-level statistics training. Also, I'd like to document some of the things I did learn over the years, and, hopefully, the things I find out while working myself out of the modelling mountain that I currently find so difficult to mount. For this I will need to use some mathematical language, which is why I just installed the MathJaX-LaTeX WordPress plugin. MathJax-LaTeX uses the MathJax JavaScript library to support LaTeX and MathML math equations in WordPress without requiring the browser to have MathML support. Read More »

[So dusted-over is my ~/jot directory that Tom Moertel, the article's author, has changed he link schema of his blog without providing redirects. (The slashes in the date turned to dashed.)

Learning to ‘hack’ with Security Override

In August 2011, probably while procrastinating learning for my university admission exams, with one mouldy foot still in my IT-past, I signed up for Security Override, an online game designed to turn network security n00bs such as myself into novices. Read More »

The Architecture of Open Source Applications book

This link to The Architecture of Open Source Applications book was gathering dust somewhere in my ~/jot directory. In true free software spirit, it is released under a Creative Commons licence and the individual chapters are readable online. Each chapter about the architecture of a particular open source software project is written by the (co-)author of that respective project. Read More »

Keeping an unsupported Mint/Ubuntu installation ‘up-to-date’

When a Linux Mint release goes out of support, together with the Ubuntu release on which it is based, the Ubuntu packages become unavailable. This can be annoying for old fossils like me who stubbornly contue to use a release that has gone out of support, as I'm doing with Mint 14 (Nadia), based on Ubuntu 12.10, (Quantal Quetzal). (“Yeah, yeah; I'll upgrade soon; I promise.”) Luckily, the out-of-support packages remain available in a different location. Read More »
