Anything can happen at Anfield

By Leave a Comment

Last night, Barcelona beat Liverpool 3-0 in the first leg of the Champions League semi-final.

Personally, I felt that Liverpool played well and was better than Barcelona during long stretches. The players were good but could not score the 2-3 clear chances they had. Salah, Mané, Wijnaldum and Milner all came really close. The Barcelona players did though, with one goal by Luis Suarez and two by Lionel Messi (his free-kick at the 80th minute was amazing).

The probability of Liverpool winning the return tie by 4-0 (or 5-1, etc.) is very low (a few percents at most). Liverpool will have to score very early and completely dominate the midfield.

Can this happen? I have some doubts, to be honest, but history shows that, at Anfield, anything can happen.

Disable tracker in Gnome if you do not need it

By 1 Comment

According to its website, “Tracker is a filesystem indexer, metadata storage system and search tool.”

“By using Tracker, you no longer have to remember where you’ve left your files. To locate a file you only need to remember something about it, such as a word in the document or the artist of the song. This is because as well as searching for files in the traditional way, by name and location, Tracker searches files’ contents and metadata.”

That’s great I guess for some people.

For me, Tracker is a massive pain as I have a lot of files, some of them huge and a lot of them being binary files (think images and photos, music files, videos, LibreOffice files, PDF documents, etc.) On my Fedora Linux installation, which is now running in a virtual machine on a brand new MacBook Pro, the Tracker extractor and indexer uses a lot of CPU resources. Too much in fact for something that I never ever use.

You see, I am an “informatician” (i.e. a computer scientist — a very bad designation — think calling a surgeon a scalpel scientist) and, as such, I make it a must to properly save all my files in folders and subfolders. I also name the files very consistently with dates, sensible use of words, etc. for proper sorting and, hence, searching.

So I don’t need Tracker as I pretty much can narrow down to the single file I need in a few seconds.

How to disable Tracker in Gnome

I found the following set of commands online which disable Tracker:

    gsettings set org.freedesktop.Tracker.Miner.Files enable-monitors false
    gsettings set org.freedesktop.Tracker.Miner.Files ignored-files "['*']"
    gsettings set org.freedesktop.Tracker.Miner.Files crawling-interval -2

Looking at the source code of Tracker,  the -2 indicates that Tracker should be disabled. The next step is to kill all current Tracker processes:

    pkill tracker

and, finally, clear the Tracker cache

    rm -rf ~/.cache/tracker

Playing Quake again after 23 years

By Leave a Comment

Quake was born when Christina and I were studying in France in 1996.

Like most people we knew, we fell in love with the game: the graphics were amazing (and we even bought a 3dfx Voodoo 2 to run it), the audio was great and the atmosphere phenomenal. As a matter of fact, Quake is one of the few games I completed. I ran it on Windows 95.

Fast forward 23 years

Today, my laptop runs Fedora Linux 29 and I only use its integrated Intel graphics chipset (despite the laptop having an nVidia chipset as well). This morning, I stumbled upon Quaddicted:

From there, I quickly discovered that, since Quake was released as open source software in 2012, a number of people have embarked on correcting bugs and enhancing the Quake engine. According to Quaddicted (and who am I to disagree!), the best engine for Linux is Quakespasm.

I quickly downloaded it and found an executable called quakespasm-sdl2 which I quickly ran. I got an error message telling me that a folder id1 was not found.

I remembered having zipped my Quake installation years and years ago and, because I am a very methodical guy, took only 5 seconds to find the ZIP. It had the id1 folder in it which I quickly copied to the Quakespasm folder. I got the Quake music. I ran quakespasm-sdl2 again and, lo and behold, Quake started in all its glory. I quickly selected the full screen option and opened a save game from decades ago and it worked! This is what you can see in the top screenshot.

But quake is more than quake…

While reading Quaddicted, a stumbled upon Quake Injector, a tool written in Java which allows you to easily download and run 3rd party maps in Quake. Think maps as levels, distinct from the Quake default levels, but as great and sometimes greater to play.

[Caveat: Quake Injector did not run at first as I had Java 11 on my Linux laptop. I had to switch to Java 8 (which I also had but was inactive)]

As soon as Quake Injector started, I installed the very highly rated DaMaul6 map and this is where I am now. Wish me luck as DaMaul6 is known to be very difficult.
