I’m a SysAdmin since 1998. Maybe a bit earlier, if you count managing our home computer. This means SysAdmin Day is also celebrating me. However, my Emacs Calendar doesn’t show it for some reason.

I’m in a team who are developing a Flask-based web application, which uses logging extensively. For a while now it spews out a lot of lines so the need arose to index them in ElasticSearch, and more importantly, to search through them for auditing purposes. This latter user story brought up one more question: why don’t we categorize our log messages? I quickly came up with an extended log format (
[auth]is the new category name):
I have recently messed up my Alembic migrations while modifying my SQLAlchemy models. To start with, I didn’t update the auto-generated migration files to name the indexes/foreign keys a name, so Alembic used its own naming scheme. This is not an actual problem until you have to modify columns that have such constraints. I have since fixed this problem, but first I had to find which column references what (I had no indexes other than primary key back then, so I could go with foreign keys only). Here is a query I put together, mostly using this article.
When creating multilingual software, be it on the web, mobile, or desktop, you will eventually fail to mark strings as translatable. I know, I know, we developers are superhuman and never do that, but somehow I stopped trusting myself recently, so I came up with an idea.
Today I needed a function to create a slug (an ASCII-only representation of a string). I went Googling a bit, and found an excellend Flask snippet. Problem is, it is designed for Python 2, so I came up with a Python 3 version.
Now that I write Python code for a living, I write a lot of functions, classes, and modules. What I still tend to forget, and also find tedious, is adding docstrings. Unlike many developers, writing documentation is not an enemy of mine, but it usually comes to my mind when I finish implementation. The procedure, roughly, is this:
Gergely Polonkai is a systems engineer of a telco company, and also a freelancer self- and software developer.
He is learning about different IT subjects since the late 1990s. These include web development, application building, systems engineering, IT security and many others. He also dug his nose deeply into free software, dealing with different types of Linux and its applications, while also writing and contributing to some open source projects.
On this site he is writing posts about different stuff he faces during work (oh my, yet another IT solutions blog), hoping they can help others with their job, or just to get along with their brand new netbook that shipped with Linux.
