Missing C3/C4 on IEC 60320 (IEC 320) Reference Chart – IEC 60320 Connectors & Plugs | StayOnline

Posted by jpluimers on 2025/12/29

I do like the [Wayback/Archive] IEC 60320 (IEC 320) Reference Chart – IEC 60320 Connectors & Plugs | StayOnline ¹, but it lacks combo C3/C4 plug/inlet:

C3 C4

From: IEC 60320 – Wikipedia (and yes: I had an old radio in my youth requiring this plug)

I bumped into the reference chart because I forgot the search term IEC 60320, and therefore searching my earlier blog posts on it ².

I did remember C13/C14 (normal appliance couplers) and C19/C20 (higher power device couplers), so I used the query [Wayback/Archive] c20 c19 amperage – Google Search giving me this table: Read the rest of this entry »

I was living under a stone: Rufus has gotten some learned some great Windows 11 tricks in 2022

Posted by jpluimers on 2025/12/29

I totally agree with [Wayback/Archive] Dustin (BusySignal) on Twitter: “when did the disk utility rufus become so awesome?” as Rufus 3.20 has added these Windows User Experience features when creating bootable Windows installation media:

  • Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0
  • Remove requirement for an online Microsoft account
  • Disable data collection (Skip privacy questions)
  • Set a local account using the same name as this user’s
  • Set regional options using the same values as this user’s

So below are some links explaining more about this feature (and how it is implemented).

Temperature controlled fans usable for DIGITUS Professional Network Wall Housing – Soho Wall Cabinet: Amazon.de: Computer & Accessories

Posted by jpluimers on 2025/12/26

TL;DR: avoid Digitus AC fans, but use DC case fans with built-in/external temperature controller plus 12V or USB-step-up power supply and optionally fan grilles/meshes.

A while ago, I bought a 7U shallow 19-inch rack cabinet to house some of our network equipment for the offices and other rooms at the top floor: [Wayback/Archive] DIGITUS Professional Network Wall Housing – Soho Wall Cabinet: Amazon.de: Computer & Accessories

Since it was to be mounted in the boiler room, which is on the top floor under a flat roof, it would get warm so I wanted fans installed in it under or over the air vents in the housing (the cabinet is delivered as flat-pack with parts pictured below and requires about half an hour assembly time):

In 2024, I missed a great flash-mob in Utrecht – Hoog Catharijne by the Wish You Were Here -Pink Floyd Project Tour

Posted by jpluimers on 2025/12/25

From [Wayback/Archive] Beach Roy☀️🏄‍♂️🏝️🏖️ on X: “Ik huil niet. Jullie huilen. Wat een ontzettend gave flashmob. Utrecht – Hoog Catharijne Wish You Were Here -Pink Floyd Project Tour – 2024”

Edit 20251227 – Note: the Twitter account does not exist any more, but the media did at the time of writing early 2025.

Currently, the Wayback Machine is having issues from The Netherlands, but hopefully their archivals appear to be complete when the Wayback Machine gets fully up again.

rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.

Posted by jpluimers on 2025/12/25

This is actually the WireGuard package you can install on pfSense CE 2.5.2 and higher: [Wayback/Archive] rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.

Note that the source code mentions a lot of web-technologies but that is because the majority of the code is the pfSense plugin. Underneath it pulls the actual build from [Wayback/Archive] git.zx2c4.com/wireguard-freebsd/snapshot which is almost exclusively C code.

Like WireGuardNT on Windows, it uses a high performance kernel mode driver.

Some more links on it:

25 years ago, around this period, the InterBase 6 / Firebird 1 prerelease gaping security hole was detected: a user politically with password correct would gain database access

Posted by jpluimers on 2025/12/24

Before Firebird version 1.0 got released, a gaping security hole that InterBase introduced in 1994 before InterBase 6.0 (mostly written in C) got open sourced in 2000 was detected by the team that frantically tried the Firebird fork to first get building on various platforms, then released.

It had a maximum CVSS score of 10.0 because it could access the security database in read/write mode, thereby allowing adding users with SYSDBA privileges.

The detection is now about 25 years ago; on 20260109 the publication (by IBPhoenix) of the bug will be 25 years ago too.

So below are some links, including the original InterBase 6 source which was hard to find as the attachments of the original release links had not been archived in the Wayback Machine.

But first some of the code parts, which also shows the source file I did find back:

n modern versions of Mac OS, like macOS Mojave, Catalina, Sierra, OS X El Capitan, and Yosemite, you can shorten the syntax considerably as so:
defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences |grep SSIDString
In prior versions of Mac OS X, you can opt for the same as the above command, or use the lengthier string below with heavy regex:
