GitHub – KirillOsenkov/LargeAddressAware: A build tools package that adds support for making 32-bit exes LARGEADDRESSAWARE (and some words on a 64-bit Delphi product)

Posted by jpluimers on 2024/06/26

[Wayback/Archive] GitHub – KirillOsenkov/LargeAddressAware: A build tools package that adds support for making 32-bit exes LARGEADDRESSAWARE

Hopefully this can be applied to Delphi projects as well. If not then in Delphi you can manually call this in an post-build task.

Addition late 20240626

[Wayback/Archive] Kirill Osenkov: “@wiert I also found that you can…” – Mastodon

@wiert I also found that you can target AnyCPU 32-bit preferred and it will give you the same address space. So that tool is only for x86.

Via [Wayback/Archive] Meik Tranel on X: “Please for the love of all that is holy. Do not build #dotnet tools to serve a non interactive task that is supposed to be run during a build – use an #MSBuild task package. Also #JS/#NPM devs should not be allowed to write tooling. Thanks for coming to my ted talk…”.

The Delphi bit inspired a few months ago by: [Wayback/Archive] Andreas on X: “Will there ever be a 64bit Delphi IDE or at least a LargeAddressAware version. Our Projekt crashes the IDE between 14-18 compilations because it runs out of memory. Maybe I have to patch the IDE myself by moving all .NET and Compiler memory allocations above the 2 GB address.”

delphi – What is the meaning of the bScan parameter value 0x45 in keybd_event? – Stack Overflow

Posted by jpluimers on 2024/06/06

From a long time go and a project that got cancelled, but maybe in the future I will need a similar thing again: back in the days not all raw key codes were readily documented or converted correctly from winuser.h to other environments (0x45 is the keyboard raw scan code value for VK_NUMLOCK of the Num Lock key).

Script alternatives to the Windows-L keyboard shortcut (SwitchUser / LockWorkstation)

Posted by jpluimers on 2024/05/23

More than a decade ago I wrote about Programmatic alternatives to Windows-L keyboard shortcut (SwitchUser / LockWorkstation).

Still, I see many scripts invoke rundll32.exe or  to call the [Wayback/Archive] LockWorkStation function (winuser.h) inside user32.dll. Don’t!

The BOOL LockWorkStation()function has a calling convention that is incompatible with rundll32.exe () which will corrupt the call stack likely will lead to random problems as after two decades, this post from Raymond Chen still holds: [Wayback/Archive] What can go wrong when you mismatch the calling convention? – The Old New Thing

How NOT to Measure Latency

Posted by jpluimers on 2024/05/15

According to @isotopp (Kristian Köhntopp ), this is one of the most important talks to watch regarding performance issues: [Wayback/Archive.is] How NOT to Measure Latency

Gil Tene provides an in-depth overview of Latency and Response Time Characterization, including proven methodologies for measuring, reporting, and investigating latencies, and overview of some common pitfalls encountered (far too often) in the field. Tene also covers specific considerations in garbage collected environments (such as Java).

It is on YouTube (embedded below the signature) as well, but the above link as synchronised slides plus video.

More places where you can get it:

A while ago Andy Gocke posted this bit of C# 11 code:

Please do not make your C# code an obfuscation contest

Posted by jpluimers on 2024/04/23

You. This is valid C# code. Guess what it does [Wayback/Archive]:

for (
  var (f,l) = (1, 10);
  f <= 10;
  Console.WriteLine($"{f} + {l} = {f + l}"),
  f++,
  l--
);

When Microsoft download URLs time out: check if it other IP addresses for the same host do work fine (it might be a regional Microsoft CDN issue)

Posted by jpluimers on 2024/03/28

A while back, early in the Wednesday morning after Patch Tuesday I performed regular updates of all the systems noticing some updates failed because timeouts on the Microsoft download servers.

Note I perform the manual steps on Wednesday as Patch Tuesday as it starts at 10:00 AM PST which is in the evening in Amsterdam. The automated steps are automated and kick in when Microsoft tells the Windows machines to update themselves.

See [Wayback/Archive] Security Update Guide FAQs

Microsoft schedules the release of security updates on “Patch Tuesday,” the second Tuesday of each month at 10:00 AM PST.

Depending on time zone(s) in which the organization operates, IT pros should plan their deployment schedules accordingly. Please note that there are some products that do not follow the Patch Tuesday schedule.

I posted a gist and a Tweet, but didn’t immediately thought of a good resolution so I postponed that until Thursday and found it:

For vscode: git-rename – Visual Studio Marketplace

Posted by jpluimers on 2024/03/26

In vscode, I have installed [Wayback/Archive] git-rename – Visual Studio Marketplace (with source code at [Wayback/Archive] adam8810/vscode-git-rename: Move or rename a file, a directory, or a symlink using git-mv).

Many people assume that git does recognise rename (or mv) operations by itself. Often it does, but it fails, and when it fails it usually is in a complex situation where it is easy to overlook it did not recognise the rename.

Failing complex situations I have encountered in the past (combined they get worse):

  • rename across several directories
  • first edit, then rename
  • first rename, then edit

So it is better to proactively perform an IDE-assisted git mv operation that informs git of the rename.

Many IDE environments support a built-in rename that keeps git mv in the loop, but Visual Studio Code does not, hence the need for this extension.

It means I agree with the question, disagree with the answer, and agree with the comment in [Wayback/Archive] VS Code ‘git mv’ to preserve file history? – Stack Overflow:
