Over the last years, Microsoft has been retiring a lot of KB articles that in some situations can be of great value, not just when using legacy systems: sometimes they are the only source of accurate information on current systems as well.
I was glad to find that many of the retired articles made it to the [Wayback/Archive.is] Microsoft KB Archive – BetaArchive Wiki.
From that page:

A while ago, I had a web page showing the logo as inline svg xml code.
Edit 20231209: [Wayback/Archive] Render SVG to PNG: Edit fiddle – JSFiddle – Code Playground (explained in [Wayback/Archive] html – Convert embedded SVG to PNG in-place – Stack Overflow by [Wayback/Archive] User anatoly techtonik – Stack Overflow) works way better than the InfoHeap link:
svg element in it (but keep the id="inputSvg" attribute!),Original content
It took a while to find a place to convert that on-line: [Wayback/Archive.is] inline svg xml to png – online html sandbox – InfoHeap (via [Wayback/Archive.is] Convert svg xml text to png image using canvas – InfoHeap):
The solution is a bit of JavaScript (quoted below) that you can run-online: modify the svg bit in it, then run it, scroll down in the result and verify if the canvas fits (when not: adapt the canvas side, then re-run).
The svg xml code needs to be all on one line, so remove any line breaks in it before running.
I have tested it in Chrome, but it should work in non-Chromium browsers like Firefox as well.
The inner workings of the JavaScript conversion code is explained in [Wayback/Archive.is] html – Convert embedded SVG to PNG in-place – Stack Overflow with more demo code at [Archive.is] Rasterizing In-Document SVG (thanks [Wayback] Phrogz!).

Below is a cool solution to refresh a page using a bookmarklet is to embed it into an iframe, then automatically reload it every interval.
It for instance works for the [Wayback/Archive.is] Woonveilig and often in Fritz!Box environments.
[Wayback] Jon described the below method as a solution for his own question, 6 years after asking it in [Wayback/Archive.is] Automatically reload page in Chrome without plugin – Super User.
So I made this a bookmark:
| javascript:document.getElementsByTagName("body")[0].innerHTML = "<iframe id=\"testFrame\" src=\""+window.location.toString()+"\" style=\"position: absolute; top:0; left:0; right:0; bottom:0; width:100%; height:100%;\"><\/iframe>";reloadTimer = setInterval(function(){ document.getElementById("testFrame").src=document.getElementById("testFrame").src },5*60*1000) |
(it is in a gist as the WordPress editors keep killing the embedded html code, despite it being escaped within <code> tags.

For a very long time (about 2 decades) Duncan Murdoch had his home page at www8.pair.com/dmurdoch which somewhere in 2021 has moved to
I figured that out thanks to some help from [Wayback/Archive] Pair Networks (@pairnetworks) / Twitter.
So you need to do a replacement of many URL link prefixes

GitKon was a cool virtual conference about git and the git ecosystem: [Wayback/Archive.is] GitKon Sept 22 – 23, 2021 – Virtual Git Conference | Presented by GitKraken
Navigation was a bit hard because of the visual overload on the site (look at the various Archive.is archivals), so here is the outlined list of sessions with the rough timestamps in the below live recordings:
Global sitemap:
Live recordings are below. Hopefully they will last and per session splits will have become available.
None of them are at listed at [Wayback/Archive.is] www.youtube.com/c/Gitkraken/videos.

After yesterdays post (which I will be editing to add some more pictures) MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp) now a call for help:
The Badge Team needs volunteers helping them on the software side.
At the badge event, the version 1.0 firmware was flashed so the badge will function perfectly fine during the event, but it would be cool if more features are available that attendees can get when upgrading at the event or downloading from the hatchery.
There is a virtual environment to test and a GitHub projects page with open issues to get started.
See the links below on how you can help:

The MCH2022 badge has an ESP32 (with WiFi!), a RP2040 and an FPGA next to a full colour TFT LCD, buttons (including joystick!), LEDs, LiPo battery, USB-C connector, micro SD-card slot and more (see below) and SHA2017 badge compatibility. How cool is that!
There is a wealth on information for this at [Wayback/Archive] Badge.team (some 22 repositories and counting: [Wayback/Archive] Badge.team: search for repositories containing mch2022).
Good starts are [Wayback/Archive] MCH2022 badge | BADGE.TEAM and [Wayback/Archive] Software Development | BADGE.TEAM (yes of course you can write your own software for it and even distribute it through the [Wayback/Archive] hatchery.badge.team Hatchery).
Below are lots of tweets including some of the Twitter retrospect that organically grew (just like the sweatschop event) on Twitter the day after.
From the original announcement [Wayback/Archive] May Contain Hackers 2022: Presenting: The MCH2022 badge! , this is what hardware is in it

Early june, I blogged about Wake-on-LAN from a Windows machine.
My plan was to adopt [Wayback/Archive.is] Wake.ps1 into Wake-on-LAN.ps1 (as naming is important).
One of the goals was to support multiple hardware MAC address formats, especially as Wake.ps1 had the below comment, but did support the AA-BB-CC-DD-EE-FF, though not the AA:BB:CC:DD:EE:FF hardware MAC address format:
<# ... .NOTES Make sure the MAC addresses supplied don't contain "-" or ".". #>
A colon separated hardware MAC address would result in this error inside the call to the [Wayback/Archive.is] PhysicalAddress.Parse Method (System.Net.NetworkInformation) | Microsoft Docs:
Send-Packet : Exception calling "Parse" with "1" argument(s): "An invalid physical address was specified."
So I did some digging, starting inside the above mentioned blog post, and adding more:
Parse method in the [Wayback/Archive.is] PhysicalAddress.cs source code in C# .NET, which contains code like this://has dashes? if (address.IndexOf('-') >= 0 ){ hasDashes = true; buffer = new byte[(address.Length+1)/3]; }
xx:xx:xx:xx:xx:xx(canonical)xx-xx-xx-xx-xx-xx(Windows)xxxxxx-xxxxxx(Hewlett-Packard switches)xxxxxxxxxxxx(Intel Landesk)
I should rename the first one IEEE 802, as per this:
The standard (IEEE 802) format for printing EUI-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (
-) in transmission order (e.g.01-23-45-67-89-AB). This form is also commonly used for EUI-64 (e.g.01-23-45-67-89-AB-CD-EF).[2] Other conventions include six groups of two hexadecimal digits separated by colons (:) (e.g.01:23:45:67:89:AB), and three groups of four hexadecimal digits separated by dots (.) (e.g.0123.4567.89AB); again in transmission order.[30]
The latter is used by Cisco (see for instance [Wayback/Archive.is] Cisco DCNM Security Configuration Guide, Release 4.0 – Configuring MAC ACLs [Support] – Cisco and [Wayback/Archive.is] Cisco IOS LAN Switching Command Reference – mac address-group through revision [Support] – Cisco), so another format to add:
xxxx.xxxx.xxxx(Cisco)
The
addressparameter must contain a string that can only consist of numbers and letters as hexadecimal digits. Some examples of string formats that are acceptable are as follows:
00112233445500-11-22-33-44-550011.2233.445500:11:22:33:44:55F0-E1-D2-C3-B4-A5f0-e1-d2-c3-b4-a5Use the GetAddressBytes method to retrieve the address from an existing PhysicalAddress instance.
I really do not have all the sources for the various representations for 48-bit MAC addresses, but I have seen them variously used:
AA-BB-CC-DD-EE-FF AA.BB.CC.DD.EE.FF AA:BB:CC:DD:EE:FF AAA-BBB-CCC-DDD AAA.BBB.CCC.DDD AAA:BBB:CCC:DDD AAAA-BBBB-CCCC AAAA.BBBB.CCCC AAAA:BBBB:CCCC AAAAAA-BBBBBB AAAAAA.BBBBBB AAAAAA:BBBBBB
From the last list, which is far more complete than the others, I recognise quite a few from tools I used in the past, but too forgot the actual sources, so I took the full list from there and tried to name them in parenthesis after the links I found above and what I remembered:
AABBCCDDEEFF (Bare / Landesk)AA-BB-CC-DD-EE-FF (IEEE 802 / Windows)AA.BB.CC.DD.EE.FF (???)AA:BB:CC:DD:EE:FF (Linux / BSD / MacOS)AAA-BBB-CCC-DDD (???)AAA.BBB.CCC.DDD (Cisco?)AAA:BBB:CCC:DDD (???)AAAA-BBBB-CCCC (???)AAAA.BBBB.CCCC (Cisco / Brocade)AAAA:BBBB:CCCC (???)AAAAAA-BBBBBB (Hewlett-Packard networking)AAAAAA.BBBBBB (???)AAAAAA:BBBBBB (???)Some additional links in addition to the ones above:
