b0rk on Twitter about getting unstuck: “debugging strategy: do the annoying thing”

Posted by jpluimers on 2025/06/04

Not just about getting unstuck during debugging: making progress is often about doing “the annoying thing”.

Tom Sydney Kerckhove on Twitter: “I haven’t found any programming tasks that an LLM could do even barely correctly. What kind of code are you all writing?!”

Posted by jpluimers on 2025/06/03

Interesting responses [WaybackSave/Archive] Tom Sydney Kerckhove on X: “I haven’t found any programming tasks that an LLM could do even barely correctly. What kind of code are you all writing?!” and later

They all come down to

  • excuses for using LLM without any substantial result (most of the results come down to one having to become the tester and fixer of the generated code without newer generated code being improved: the opposite of coaching an apprentice)
  • become better at prompting (which is basically regarding the prompt as a new programming language: been there, done that)

[WaybackSave/Archive] One of the “become better at prompting” replies referred to a blog post disguising prompting as writing lots of unit tests: [Wayback/Archive] The Cline AI Assistant is Mesmerizing · mtlynch.io

“How come these shapes are so DIFFICULT??”

Posted by jpluimers on 2025/06/03

Cool video about how developers feel when others (like QA) test or use the software they have just built:

[Wayback/Archive] Devs watching QA test the product – YouTube

I got to the video via [Wayback/Archive] sanja zakovska 🌱 on Twitter: “Devs watching QA test the product… “ to which the author responded with

Barcodes van statiegeldflessen

Posted by jpluimers on 2025/05/29

Het overkomt te vaak dat barcodes beschadigd of overplakt zijn (hallo Too Good to Go, hallo “samen minder verspillen” van Jumbo en vergelijkbare acties)

Daarom wat barcodes van producten die je er overheen kunt plakken:

What is the Python 3 equivalent of “python -m SimpleHTTPServer” – Stack Overflow

Posted by jpluimers on 2025/05/29

Now that Python 2 has been dead for long enough (has it been unsupported for 5 years? yes it has: [Wayback/Archive] Status of Python Versions), it was finally time to change my alias for running a local web-server to serve files from a directory (:

So, from [Wayback/Archive] What is the Python 3 equivalent of “python -m SimpleHTTPServer” – Stack Overflow (thanks [Wayback/Archive] ryanbraganza, [Wayback/Archive] k.avinash and [Wayback/Archive] Petr Viktorin):

python -m http.server 8000, it will start the server on port 8000

Bypassing ACLs with SeRestore privilege. And very simple User to LocalSystem elevation. – YouTube

Posted by jpluimers on 2025/05/28

This is cool and scary at the same time, especially since I knew about other privileges (SeDebugPrivilege comes to mind).

Granted you need to be local administrator for this, but still: for some tasks you do not need to elevate in the traditional way, but just give your current token more privileges.

Via [WaybackSave/Archive] Grzegorz Tworek on X: “Friendly Reminder: If you have admin privileges but lack the necessary file permissions, you can leverage the SeBackup/SeRestore privileges directly from cmd.exe! There’s no need to elevate to LocalSystem, duplicate TrustedInstaller, or use similar methods. Simply enable the …”

b0rk: “debugging strategy: jump into a REPL” / Twitter

Posted by jpluimers on 2025/05/28

[Wayback/Archive] 🔎Julia Evans🔍 on Twitter: “debugging strategy: jump into a REPL” (more platforms in the replies to the Tweet)

title: jump into a REPL In dynamic languages (like Python / Ruby / JS), you can jump into an interactive console at any point in your code. Here's how to do it in a frontend Javascript program: 1. edit your code code: ``` my_var = call_some_function() debugger; ``` 2. refresh the page 3. play around in the developer tools console! you can call any function you want / try out fixes! How to do it in other languages: Ruby: `binding.pry` Python: `import pdb; pdb.set_trace()`

Posted by jpluimers on 2025/05/27

On my reading list (plus read/watch the links it mentions): [Wayback/Archive] 0x00 – Introduction to Windows Kernel Exploitation // by [Wayback/Archive] wetw0rk (@wetw0rk_bot) / X ([Wayback/Archive] wetw0rk.github.io).

Hopefully by now, more episodes have been published.

Links from this one, including archived versions split in the same sections as the above article:

Naming things isn’t hard: if it contains a number, include the unit in the name (your timeout might not be in nanoseconds)

Posted by jpluimers on 2025/05/27

This case, it was C# accessing a SQL back-end, but the responses to the Tweet how so many more examples not even related to software development.

Remember that plane crashing because they overloaded while they thought the fuel load numbers were in Imperial pounds where in fact they were in metric kilograms?

That’s why naming things that contain numbers should contain the unit in their name!

Tweet: [Wayback/Archive] Nick Craver on Twitter: “Troubleshooting a hanging test suite and godDAMMIT. “In seconds”. Integer timeouts should be a felony offense punishable by an indeterminate amount of seconds/milliseconds/hours/fortnights/whatever the judge chooses.”

var csb = new SqlConnectionStringBuilder(TestConfig.Current. SQLServerConnectionString){ ConnectTimeout = 2000 }; int SqlConnectionStringBuilder.ConnectTimeout { get; set; } Gets or sets the length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. Returns: The value of the SqlConnectionStringBuilder, ConnectTimeout property, or 15 seconds if no value has been supplied.

Online .NET source code browsers for both .NET Framework and .NET Core

Posted by jpluimers on 2025/05/22

I used these .NET Source Browsers quite few times over the last decade, first for the .NET Framework and later for .NET Core (now called .NET, sometimes .NET Runtime) as well, but forgot to blog about them, so now that I discovered there is one for the Roslyn Compiler Platform as well, let’s list them all:

It was introduced as [Wayback/Archive] referencesource-beta.microsoft.com by [Wayback/Archive] A new look for .NET Reference Source – .NET Blog which explains how to use it for browsing (on-line and off-line), Visual Studio integration, debugging, and more. In about a month however it got out of beta and became the primary as it functioned so well (you can verify this while browsing through the 2014 Wayback links).

All are powered by [Wayback/Archive] KirillOsenkov/SourceBrowser:
