Since the recent acquisition of GitHub by Microsoft, a lot of people and companies are migrating to GitLab.

It is really unbelievable but it has been more than one year since I have started writing this blog.

Out there, in the wild exists a lot of different authentication schemes or methods however one of them which is relatively popular because it’s implemented in most popular browsers at the moment, has this one peculiar “bug” in its specification - you cann…

Are you working with git repositories in which a lot of code churn is happening?

If you have not known before, scanf(3) and fgets(3) are both functions intended for reading something from standard input and doing something with the result - in the former case it is interpreted and the results might possibly be stored in specified argu…

I see time and time again this myth that programming languages have varying speeds perpetually peddled in various discussions between programmers in different IRC channels, forums, and so on.

You could probably find “Code Complete” by Steve McConnell in any of the top 10 lists of books recommended to read for all programmers.

You may currently have this pipe-line in your CI/CD process that involves running ovftool directly on your ESXi host so as to deploy an OVA appliance directly from it and with as less overhead as possible as in this tutorial on virtuallyGhetto or you could

Unfortunately but the specter of Internet censorship has finally came to Lithuania a few years ago.

Recently I ran into an issue where this, for example, code fails: import os os.rename('/foo/a.txt', '/bar/b.txt') Traceback (most recent call last): File "", line 1, in OSError: [Errno 18] Invalid cross-device link The documentation for the os module s…

Introduction Let us say that you are using an vSphere (VMWare vCenter + one or more ESXi servers) environment in your company and you are creating virtual machines pretty often.

Intro Did you know that in Python 2.x you can do the following?

tl;dr: use the official taxi service that is right outside the airport, on the left when you leave through the door.

Introduction I have noticed that newbies sometimes fail to understand why, for example, sudo echo “hi” > /tmp/test will create a file /tmp/test with whatever effective user ID and effective group ID the command is ran with.

Programmers and IT people are often shunned for being shy, timid, fearful, or just in general - we are being thought of someone who have no social (soft) skills.

Intro Today I wanted to talk about unwinding and releasing resources in C functions.

There is a pretty neat tool called ovftool that makes it easy to deploy an OVA/OVF from any source or extract the contents of an OVA.

Nors man politika atrodo kaip nuobodus dalykas tačiau kadangi šitas liečia ir mane, ir kadangi niekas apie tai nekalbėjo tai nusprendžiau parašyti straipsnelį apie tai kas yra PRNG ( pseudo-random number gene rator arba pseudo-atsitiktinis skaičių generat…

I encountered an interesting behavior the other day when trying to use HTTP and/or HTTPS proxy on a GNU/Linux machine. cURL and friends read environment variables called http_proxy and https_proxy.

Time and time I see people who follow all these random online tutorials and then when something does not work they become dazed and confused.

Recently I have been trying out a pretty old phenomena by now that is called “audio books”.

Nowadays it seems like we are on an information highway and it is very hard to keep up with all the knowledge.
