Recently upgraded CPU in my ancient laptop from i7-4800MQ to i7-4940MX, which is Extreme Edition, and need legacy Intel Extreme Tuning Utility, version XTUSetup 6.5.1.360 is compatible.

The number 2025 is indeed a fascinating one with numerous interesting mathematical properties, because 2025 can be obtained by squaring the 9th triangular number and as result, one of the most remarkable facts about 2025 is, that it’s the sum of the cubes of all single-digit numbers at the same time:

B&R PLC could be programmed with C and C++. But you can also use Assembly. Below short instruction how to do that.

It is necessary to set Working Directory, otherwise ConEmu will not start Far Manager.

The AutoHotkey script for Win+F:

#Requires AutoHotkey v2.0

#f::
{
    SetWorkingDir("C:\Program Files\ConEmu")
    Run ("C:\Program Files\ConEmu\ConEmu64.exe")
}

B&R PLC could be programmed with C++. State Machine is common used pattern. There are lot of examples of how to implement State Machines in C++. One of the example was taken and turned to B&R State Machine

Today I noticed that my computer was slower than usual. A brief investigation revealed that PowerLauncher.exe was causing other running MSI installers to fail when setting up shortcuts.

The DICONDE Value Representation of a Data Element describes the data type and format of that Data Element’s Value(s).

Time to time I need “quick and dirty” benchmark to check performance. Sometimes using CPU Bench from CPU-Z or AIDA, but there is quicker way with Power Shell…

I was experiencing extremely poor performance of the VMWare Workstation on a Xeon PC running Windows 11 LTSC 24H2. Below the command with some magic.

In some cases we need to measure a very short intervals (hundreds of the CPU Tacts) directly in Assembler. We can perform measurement by using cpuid/rdtsc combination.

Collection of useful small Snippets

Small but useful snippet about CPU’s Name and to get it programmatically using WMI. Useful for Information and benchmarking purposes.

In some cases we need to have dedicated Drive in absence of the physical Drive. In this case we can add drive mapped to the Folder. Typically this could be done using SUBST command, but there is more convenient way.

Sometimes you need to prevent Windows updates and following restarts of the PC (for example during long endurance test while PC Stays connected to Internet). An easiest way to do this - is just set Metered Connection to public interface

A very simple and basic TCP communication example for Python and LabVIEW
