Funny how Generating complex math visualizations in SVG using C# and ILNumerics and MathViz (no, not this MathViz!) look so similar.
I hope the MathViz code becomes public one day.

About a year and a half ago, I wrote about a Batch file to “Keep Alive” a CMAK generated VPN connection in Windows 7.
It uses ping to wait a certain amount of time, but it has the drawbacks of
Since then, I learned that since Windows Vista and up has timeout command that just waits:
timeout /t 600 /nobreak
Two parameters are used:
(the example is 10 minutes, I use it to regularly run FlushFileCache.exe or FlushMem.exe to empty the Windows file chache and release memory – often more than a gigabyte – back to Windows)
There is also sleep.exe, but that requires the Windows Resource Kit or Windows Server 2000/2003.

Glad I found back this G+ post by André Mussche:

TIP: I got a 2nd screen with touch (on Win7), however default when touching the second screen it “clicks” on the main (1st) screen. Using “Tablet PC Settings” I got this switched to the correct 2nd screen.
I had exactly the same problem, and this solved it.

StackOverflow user David Heffernan – Stack Overflow has an interesting take on Delphi postbuild events:
At the moment my actiona read:
if exist PostBuild.bat call PostBuild.bat $(Platform) $(Config) $(OutputDir)And then the
PostBuild.batscript calls a Python script so that I can write my scripts in a real language.I actually impose the build actions in a shared option set that I reference from all of my projects. That way I enforce consistency and predictability.
I know others use tools like FinalBuilder but building is so important that I feel it’s worth my effort in rolling my own tooling.

Hopefully this command (ran as administrator) will fix the high CPU usage of TiWorker.exe on one of my Widows 8 machines:
DISM /online /cleanup-image /restorehealth
It took almost an hour to run…
| C:\bin>DISM /online /cleanup-image /restorehealth | |
| Deployment Image Servicing and Management tool | |
| Version: 6.2.9200.16384 | |
| Image Version: 6.2.9200.16384 | |
| [==========================100.0%==========================] | |
| The restore operation completed successfully. The component store corruption was repaired. | |
| The operation completed successfully. |

One of the easy things in *nix is to set the value of an environment with the output of a command.
Something like this is possible in Windows too, but you have to instruct Windows to keep an empty set of delimiters to capture the full first line.
There is also a small but important difference between Windows and *nix upon command failure: *nix will always return an empty value, but in Windows you must make sure to empty the value first.

Some things you have done for ages, are already phrased so nicely, the only thing you can do is quote.

The fact that the [WayBack] 31-character limit on ClientDataSet field and index names is worse, but I just encountered this GetParamNameWODog function in a Delphi 3rd party library:
| function GetParamNameWODog(const ParamName: _string): _string; | |
| begin | |
| if (ParamName <> '') and (ParamName[1] = '@') then | |
| Result := Copy(ParamName, 2, 1000) | |
| else | |
| Result := ParamName; | |
| end; |
What’s wrong with using the Length function here?
Yes, SQL Parameter names will probably less than 1000 characters, but then the 1000 literal should be a constant with a meaningful name, and the '@' literal should be too. Read the rest of this entry »

(English translation below)
Edit 20230510 – added new URLs after the AHN viewer moved from ahn.geodan.nl to new domains ahn.arcgisonline.nland www.ahn.nl.
Veel van Nederland ligt onder zeeniveau, inclusief de meeste plaatsen waar ik gewoond heb, maar ik wist nog niet hoe ver het van N.A.P. “zeeniveau” afweek.
Via toeval kwam ik er achter dat dit on-line heel makkelijk op postcode opvraagbaar is, met een URL als deze:
http://ahn.geodan.nl/ahn/viewer3/zoekpc.php?postcode=1060NPhttps://ahn.arcgisonline.nl/ahnviewer/?find=1060NP
Je krijgt dan een resultaat als dit:
Volgens AHN2 is de gemiddelde hoogte in postcodegebied 1060NP -1.8 m.
(Inmiddels – 2023 – geen tekst meer met gemiddelde hoogte, maar als je klikt op een locatie krijg je de gemeten hoogte aldaar)
Onderaan de postcodes waar het om gaat.
Vrijwel mijn hele leven was dus beneden zeeniveau, maar ik ben boven zeeniveau geboren (:
En als bonus: AHN Viewer en AHN [Wayback/Archive] AHN Viewer | AHN (snapt geen URL parameters) en [Wayback/Archive] AHN-viewer (snapt wel URL parameters, zie [Wayback/Archive] ahn.arcgisonline.nl/ahnviewer/Release_notes_versie_2_februari_2019.pdf).
Er is ook een postcodetool, maar die snapt geen URL parameters: [Wayback/Archive] Postcodetool
Most of The Netherlands is below sea level, including most of the places I lived, but I didn’t know how far from N.A.P. “sea level” that was.
By coincidence, I found out that it is easy to find this relative altitude by Dutch poascal code with a URL like this:
http://ahn.geodan.nl/ahn/viewer3/zoekpc.php?postcode=1060NPhttps://ahn.arcgisonline.nl/ahnviewer/?find=1060NP
It will get you a result like this, where the last number indicates altitude:
Volgens AHN2 is de gemiddelde hoogte in postcodegebied 1060NP -1.8 m.
(By now – 2023 – no text with average altitude, but if you click you get the measured altitude value)
Below is a list of postal codes where I lived or where my post got delivered.
So I lived most of my life below sea level, but was born above it (:
As a bonus, I also found AHN Viewer and AHN [Wayback/Archive] AHN Viewer | AHN (does not allow URL parameters) and [Wayback/Archive] AHN-viewer (allows URL parameters, see [Wayback/Archive] ahn.arcgisonline.nl/ahnviewer/Release_notes_versie_2_februari_2019.pdf).
There is even a postal code tool, but it does not support URL parameters: [Wayback/Archive] Postcodetool
