Slow RSS feed on your blog? Here’s what to do.

A friend was trying to subscribe to my RSS channel recently but his NewsBlur was reporting a timeout nine attempts out of ten. I tried accessing my /feed/ url locally but got a timeout, too. What the &%#$&@@#? After some googling and fiddling I figured what was wrong: size matters! My RSS settings were: show […]

Economical mumbo-jumbo

Whilst browsing the Internet I recently ran into an interesting (and probably totally unreallistic) idea: universities should be free from charge for all students. Their (i.e. universities’) income should be funded exclusively off a [simple_tooltip content=’Or any other agreed %’]10%[/simple_tooltip] tax charged unconditionally from all alumni for the first [simple_tooltip content=’Or three because why not’]ten[/simple_tooltip] […]

Next prime date

Dates in Ireland are usually written as DD MMM YYYY i.e. 5 Sep 2016 or 12 Jan 2000 and so on. However, from database perspective (which is my personal favourite) I like storing date values as integers of YYYYMMDD i.e. 20160905 or 20000112 etc.

0, 1, 8, 144 (EN)

While surfing the Internet I recently found an interesting (although completely incomprehensible) proof of a conjecture stating that 0, 1, 8 and 144 are the only perfect squares in the famous Fibonacci sequence.

For each file sent over via the ftp channel I was supposed to generate an empty *.OK file and send it over immediately after the main file transfer was completed.

Xenial Xerxus and WordPress – upgrading your VPS

It is very important to keep your software updated. Forget to upgrade your apache to the latest version and you’re screwed. Forget to install recent security patches and you’re pwned. And so on.

UTF != UTF

I have recently faced a very annoying issue with one of the ETL processes. Very annoying issues are often easily resolvable in simple ways[citation needed] and thankfully this was one of them. However, before I managed to solve it, I wasted a whole bunch of otherwise perfectly usable minutes which is something I always loathe. […]
