string – Check if MyString[1] is an alphabetical character? – Stack Overflow (and how Embarcadero broke one of the product version neutral redirects)
Posted by jpluimers on 2024/09/24
Quite a while ago [Wayback/Archive] string – Check if MyString[1] is an alphabetical character? – Stack Overflow asked by [Wayback/Archive] User Jeff was answered by [Wayback/Archive] Andreas Rejbrand:
The simplest approach is
function GetAlphaSubstr(const Str: string): string; const ALPHA_CHARS = ['a'..'z', 'A'..'Z']; var ActualLength: integer; i: Integer; begin SetLength(result, length(Str)); ActualLength := 0; for i := 1 to length(Str) do if Str[i] in ALPHA_CHARS then begin inc(ActualLength); result[ActualLength] := Str[i]; end; SetLength(Result, ActualLength); end;but this will only consider English letters as “alphabetical characters”. It will not even consider the extremely important Swedish letters Å, Ä, and Ö as “alphabetical characters”!
Slightly more sophisticated is
function GetAlphaSubstr2(const Str: string): string; var ActualLength: integer; i: Integer; begin SetLength(result, length(Str)); ActualLength := 0; for i := 1 to length(Str) do if Character.IsLetter(Str[i]) then begin inc(ActualLength); result[ActualLength] := Str[i]; end; SetLength(Result, ActualLength); end;
Back in 2011 I added a comment that for more than a decade would redirect to the most current documentation on the IsLetter method:
+1 for using
IsLetterwhich checks the Unicode definition for being a letter or not [Wayback] docwiki.embarcadero.com/VCL/en/Character.TCharacter.IsLetter
Back then, Delphi X2 was current, so it would redirect
- from [Wayback] http://docwiki.embarcadero.com/VCL/en/Character.TCharacter.IsLetter
- to [Wayback] http://docwiki.embarcadero.com/VCL/XE2/en/Character.TCharacter.IsLetter
- then to [Wayback] http://docwiki.embarcadero.com/VCL/XE2/en/Character.TCharacter.IsLetter
- ending at [Wayback] http://docwiki.embarcadero.com/Libraries/XE2/en/System.Character.TCharacter.IsLetter
After a long outage in 2022 (see The Delphi documentation site docwiki.embarcadero.com has been down/up oscillating for 4 days is now down for almost a day.) only the Alexandria help was restored.
This killed the above redirect.
Luckily [Wayback/Archive] George Birbilis noticed that and commented this:
@JeroenWiertPluimers the correct link now is: docwiki.embarcadero.com/Libraries/Alexandria/en/…
In order to refer to the most recent Delphi version, now you have to use [Wayback] http://docwiki.embarcadero.com/Libraries/en/System.Character.TCharacter.IsLetter.
This redirects:
- via [Wayback] http://docwiki.embarcadero.com/Libraries/Alexandria/en/System.Character.TCharacter.IsLetter to
- to [Wayback] https://docwiki.embarcadero.com/Libraries/Alexandria/en/System.Character.TCharacter.IsLetter
The above breaks the help integration from older Delphi products which is bad. It is also bad because it makes it harder to port legacy Delphi code to more modern Delphi versions.
Hopefully the above gives you a bit insight how the docwiki help system was designed and what is left of that design.

Thread by @LetheForgot to @SwiftOnSecurity on Thread Reader App – Windows boot recovery
Posted by jpluimers on 2024/09/23
[Wayback/Archive] Thread by @LetheForgot on Thread Reader App:
What we did was use the advanced restart options to launch the command prompt, skip the bitlocker key ask which then brought us to drive X and ran “
bcdedit /set {default} safeboot minimal“which let us boot into safemode and delete the sys file causing the bsod.Not scalable at all but let us get vital systems running while we try to solve the bootloop en masse
Don’t forget to renable normal booting afterwards by doing the same but running “
bcdedit /deletevalue {default} safeboot“
Just in case another event like the 2024 Crowdstrike debacle happens.

Fixing the date/time of a ST-977 or ST-977T weather station
Posted by jpluimers on 2024/09/23
A long time ago I asked about the manual for a Daryis ST-977 weather station, but got no response from the manufacturer or anyone else.
So about 9 months later the topic came back up and I did get some responses, most suggesting to use the SET button which I already tried earlier.
I retried and found out the button was both bouncing and needed to be held for a really long time (15+ seconds!) to even switch to “edit” mode.
With 4 AA batteries in the base it at least should survive a power outage and hopefully by now we have switched away from using daylight saving time in Europe so no time changes are needed in the future.
Later I found out the FCC was on the external sensor and could find back a manual of a similar model:

Hopefully by now the choco client will be more resilient and informative about Chocolatey maintenance windows (and maybe even about any disruptions mentioned at status.chocolatey.org)
Posted by jpluimers on 2024/09/19
Reminder to check-out of the 2015 issue mentioned in the tweets below has been had any progress.
At the time of tweeting, choco has no notion of [Wayback/Archive] status.chocolatey.org which would be very helpful to point to in case of errors on time-outs on chocolatey server calls especially if it could interrogate and inform of maintenance windows and outages when things fail on the client side.
