Can you imagine MS-DOS 6.2 recognising an 8 gigabyte SD card and allowing it to format it with multiple 2 gigabyte partitions?

That moment you facepalm yourself because you forgot that particular machine won’t read SD cards because they are too big for the SD card reader in it: SD goes up to 4 gigabyte, anything bigger (nowadays basically everything) requires SDXC or SDHC compatible readers.
Quotes from Wikipedia:
However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade.[11] Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards.[12][13][14]
Older host devices generally do not support newer card formats, and even when they might support the bus interface used by the card,[6]there are several factors that arise:
- A newer card may offer greater capacity than the host device can handle (over 4 GB for SDHC, over 32 GB for SDXC).
- A newer card may use a file system the host device cannot navigate (FAT32 for SDHC, exFAT for SDXC)
- Use of an SDIO card requires the host device be designed for the input/output functions the card provides.
- The hardware interface of the card was changed starting with the version 2.0 (new high-speed bus clocks, redefinition of storage capacity bits) and SDHC family (Ultra-high speed (UHS) bus)
- UHS-II has physically more pins but is backwards compatible to UHS-I and non-UHS for both slot and card.[27]
- Some vendors produced SDSC cards above 1GB before the SDA had standardized a method of doing so.

Up until Widows 8.1, you could use wuapp to start the Windows Update panel.
For a while, Windows 10 needed a cumbersome language specific workaround described at Windows 10 – language neutral batch file to start Windows.
That stopped working after a few builds, but I forgot to make a note in which build exactly. Already in Windows 10 build 10122, the icon in wucltux.dll, so this might have been shortly after the initial “RTM” (retroactively named 1507).
So for a while, I had this batch file:
Since then I had to maintain too many locales running Windows 10. So here is the batch file:
for /f "delims=" %%A in ('PowerShell -Command "(Get-Culture).Name"') do explorer "%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\%%A\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms"It uses these tricks:
- Set output of a command as a variable (in this case a for loop variable)
- Execute PowerShell script in a .bat file
- PowerShell Get-Culture (which gets a .NET CultureInfo instance)
- CultureInfo.Name property (which has the nl-NL, en-US, etc codes in it)
But now I have extended it to support old and new Windows versions:
if exist %windir%\System32\wuapp.exe ( %windir%\System32\rundll32.exe url.dll,FileProtocolHandler wuapp.exe ) else ( %windir%\explorer ms-settings:windowsupdate )

Today, Niklaus Wirth, “father” of The Pascal Programming Language turned 85.
Happy birthday!
Almost 50 years ago, Niklaus Wirth submitted his famous paper “The Programming Language Pascal” which was published early 1971
Luckily it is archived on both the WayBack machine and Archive.is as the only PDF copy I could find on-line isn’t always on-line: http://oberoncore.ru/_media/library/wirth_the_programming_language_pascal.pdf
Originally it was published by Niklaus Wirth in Acta Informatica, Vol. 1, Fasc. 1, 1971 pp. 35-63
He has been very active, just browse through the [WayBack] List of computer science publications by Niklaus Wirth
To celebrate his birthday, here are some interviews with him:
If you like the ones above as much as I do, then search for more: there are plenty!

Interesting read [WayBack] Mysterious Case Of Wrong Value.
In order to capture by value (which in C++ you can specify), you need an intermediate function like Dalija describes:
function CreateFunction(Value: Integer): TFunc<Integer>;
begin
Result :=
function: Integer
begin
Result := Value;
end;
end;

Somehow I’ve been doing Unix like work off and on for most of my life. So I know many ancient shell shortcuts (like Ctrl-E for end-of-line and Ctrl-A for start-of-line) by heart.
Many don’t, or even list shortcuts as if they are for the shell, but in fact aren’t.
So here are some links that distinguish between various kinds of keyboard shortcuts and give some insight in the history of these shortcuts (that go back into the 1970s, yes I’m that old).

Of course you don’t want this. So by the time you read this, the connection has been closed.
For testing some Internet of Shit stuff from a client that cannot do SFTP, I needed a temporary FTP accessible connection.

Via seedstudio, I bumped into EasyEDA – Wikipedia. It seems there are a lot of on-line tools that allow you to draw and often simulate electronics.
Time to put them on my list of stuff to play around with:
Circuitlab also has a nice free interactive book: [WayBack] “Ultimate Electronics” Book – CircuitLab A free interactive electronics textbook, “Ultimate Electronics”
Later – via issue #1 of [WayBack] HackSpace magazine: The new magazine for the modern maker – I also found out about Fritzing which is off-line native software that I want to check out as it is open source:
It helps a lot knowing there are various Electronic symbol – Wikipedia: Standards for symbols, covering much more than the one below:
To make it easier, power supplies have a host of different symbols for the same things. For instance, DC can have 3 or more different symbols. [WayBack] Electric Current Symbols
