I wrote this post half a year ago, but forgot to publish it. Nevertheless, I think it can still be useful. As you may already know, Synology still hasn’t released a fix for this vulnerability, even though it was discovered almost a year ago. I use an old Synology RS3412RPxs server. The latest DSM version […]

Resizing the root partition on a server 12 miles away seemed a bit risky. The root partition is on a software RAID1 mirror, no LVM. Twelve years ago I left only 2 GB for the root partition. I wanted to upgrade to Ubuntu 20.04.5 and the small size quickly became a problem. I managed to […]

A few years ago my teammate came up with this statement. At first we misunderstood each other. I thought of integer numbers while he meant floating point. I know how the processor represent floats and I’m aware of how/why floating point numbers are normalized or rounded. But to be honest, I never thought the order […]

It can be annoying if you use your computer 24/7 and when you don’t interact with the desktop, your machine will go into sleep after a while. If you’re using the PC remotely, you cannot bring it back from sleep. You can also turn off sleep mode manually in Power & sleep under System preferences […]

Another day of sadness to mark on the calendar, as someone has written on the World of Spectrum forum. He passed away on 2021.09.16 at the age of 81. I owe my interest and love in computers to him. Rest in peace Sir!

After installing a 4G/LTE USB stick on a Windows 7 desktop the TCP communication on localhost has effectively stalled. Interestingly, the remote traffic was not affected. Local services can be reached by remote clients and remote services can be accessed from the desktop, only the localhost (127.0.0.1) is affected. Still ping (ICMP) works on localhost […]

This is a quick update to the version I published many years ago. A lot has changed under the hood and yet much remains the same. Basically, the DirectX 9 API was replaced by Direct 3D 11 and a few minor bugs was fixed. We played a lot with this version on Windows 10 so […]

Some people think 256 bytes doesn’t enough for anything. To be prove they’re wrong just watch “Puls by Rrrola” or “Stainless Steel by Digimind” on Youtube. You can find more jaw-dropping products if you search for “256b demo”. I created a simple waving-colors effect which was called color-plasma in the old demo days. As simple […]

We have a few hundred Windows PCs across the country. It is essential to keep the OS up to date, just think of the new BlueKeep vulnerability. These PCs are running 7/24 unattended, so we need to automate almost everything, including the Windows Update configuration. These PCs are completely separate from the intranet and do […]

In the perspective of an engineer… I started working as a Service Quality engineer at a telecom company in 2001. After many small projects a manager asked me whether I can create a software to grab the content of our entire mobile site to verify everything, literally (broken links, grammar, changes, pictures etc). Mobile sites […]
