Still a great way to stress test CPUs: About Intel Burn Test…

Posted by jpluimers on 2022/05/16

IntelBurnTest is a wrapper around the [Wayback] Intel Linpack benchmark ([Wayback] Windows download) and still a great way to test CPUs.

From [Wayback/Archive.is] reddit – About Intel Burn Test… : overclocking

“Pinhedd: “Both IBT and Prime95 are similar in that they stress floating point arithmetic and memory subsystems. They are different in that IBT uses Linpack (solving linear equations) while Prime95 calculates Mersene Primes.
IBT is generally regarded as being far more aggressive in the short term, which makes it great for testing ultimate stability. IBT will easily drive load temps up to 20 degrees higher than Prime95, this is well known and is a defining feature of the program.
Unfortunately, the Linpack benchmark was designed for supercomputers (hence the floating point part, for modeling continuous phenomenon) so it really pushes desktops to the limit, far beyond what any application will do. This means that IBT may fail on commercial CPUs that are running at stock settings simply because Intel doesn’t test them to that extent.

Too bad it is not open source and steadily at version 2.54, but then again, there is so little to maintain when the underlying tests basically do not change.

This is one of the ways to download it (it is not on chocolatey): [Wayback] Download IntelBurnTest 2.54 – MajorGeeks (actual download: [Wayback] IntelBurnTest.zip.

More downloads via [Wayback] IntelBurnTest – Google Search.

Jeff Geerling on Twitter: “I plug computers into my computers…” is indeed a PCIe KVM board based on a Raspberry Pi Compute Module 4

Posted by jpluimers on 2022/05/10

Last month, I wrote

Hopefully the picture below is the board of a PCIe KVM board based on a Raspberry Pi Compute Module 4 supporting Power over Ethernet (PoE). At least it seems to looking at the thread started by…

The thread was by Jeff Geerling on Twitter: “I plug computers into my computers…”.

Jeff followed up on this much sooner than I expected with [Wayback/Archive] Jeff Geerling on Twitter: “Hey look! That computer inside a computer thing is real now! It’s the PCIe version of the Blicube KVM: …”

Converting an existing XP machine to a VMware ESXi  Virtual Machine and having boot issues?

Posted by jpluimers on 2022/05/02

A while ago I wrote about Stop 0x0000007B after converting an existing XP machine to a Virtual Machine (ESXi, Hyper-V, or other).

After this, the machine still had boot issues (a grey or black screen after boot, unless booted via Grub from a rescue CD).

The solution in retrospect was simple, but I only figured out after the fact what the solution had done.

Of course this gave me a facepalm moment, as back in the days, this was exactly the warning I gave everyone when installing Windows XP on ESXi anyway: use a SCSI buslogic based virtual disk, not an IDE or SATA virtual disk.

The reason is that Windows XP does not like the IDE/SATA disk that VMware provides. Windows Vista and up are less of a problem.

This is indeed what my practical solution did:

  • VMware Converter 4.x creates a VM with an IDE/SATA disk (as it cannot talk to the more recent ESXi versions at all because of API changes)
  • VMware Converter 6.x creates a VM with a buslogic SCSI base disk (and it can create it directly on your ESXi rig, though it will use a directory in the root of your data store, even if you prefer it somewhere deeper in the directory tree)

It would also very much match the below issue that Jeff raised:

Some notes on receiving ADS-B signals and feeding them to the OpenSky Network and other flight tracker

Posted by jpluimers on 2022/04/07

Long story short: in many countries, flight operators overload larger and larger portions of their country with excessive noise levels. Somehow they seem to circumvent regulations over and over again.

The Netherlands is no exception, having regulations based on noise “estimates” instead of measurements, and the measurements that are done being owned by the flight operators.

A while ago, the public started to do their own measurements, for instance by the Explane app which relies on the OpenSky Network for flight data.

Living near to an airport that has sleeping slots for their surrounding inhabitants (some 1.5 million plus people) of roughly 23:00-02:00 and 02:30-06:00) the public cost are ever increasing, especially with the planned opening of a new airport causing the split of the flight paths to affect some 5 million inhabitants, I decided to at least feed the OpenSky Network for better coverage of large parts of the sky around the first and second airport.

Also of interest is ADS-B Exchange as it provides unfiltered data:
