I recently acquired a new screen. You can see it in my other post "Working with three screens". Ubuntu/Linux has a few problems, and one of them is that touch device inputs are bound to the entire "visible" space of all monitors. This means that if I click on one...

Whoever says that having more than one screen is not productive, has not tried it. Until now I have worked with two screens (the laptop and the big 29" screen). Today I bought a new screen/monitor that is small, lightweight and portable (I can carry it in my backpack and...

This error means that your CA root certificate is out of date. If your CA root certificate needs to be updated, you will not be able to upload or extract from the GIT repositories. It means that you can't do either "git pull" or "git push" because you get an...

The apt package manager saves a list of packages so you don't have to download it every time. When a Linux installation reaches a certain age the apt cache can take up several tens of gigabytes. APT does not clean the cache automatically, so it may contain obsolete packages in...

I have done tests with "New Relic", and the truth is that they are expensive but it is worth having statistics of this type. Right now I have some servers that use NewRelic, and others that use Datadog. Both are very good services, they are different, but they are used...

It's a note for my future self, that every time I need it I have to look it up on Google. This way I already have it more handy and easy to find. .tar.gz files: Compress: tar -czvf packaged.tar.gz /folder/to/package/ Unzip: tar -xzvf archive.tar.gz . tar files: Pack: tar -cvf...

I recently discovered Carrd.co It is a simple platform to create Landing pages (the typical landing pages). There are many tools similar to Carrd.co, some free and some much more expensive. Why and what am I using it for? I am a FullStack web developer. I can perfectly do the...

In all my servers (Linux) I have rs ync installed. Rsync allows to copy files, or rather synchronize them, between different servers. What makes it stand out is that it does it incrementally, fast and in a very simple way. This means that it only sends the files that have...
