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()`

0x00 – Introduction to Windows Kernel Exploitation //

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.

Office suites trick I was unaware off: you can use images as background of shapes, then distort by moving the corner points

Posted by jpluimers on 2025/05/26

The below example is in Excel, but it holds for many other drawing tools in other office suites as well (like the ones in OpenOffice and successors like LibreOffice, Apple Pages in iWork, and others from the list of office suites):

  1. Insert a shape
  2. Move the corners so it covers the area you want a screenshot in
  3. Modify the shape background to contain the screenshot as background

(you can exchange steps 2 and 3 if you wish, and even go for more complex shapes – including ones where you can add corner points – to better fit the area where you want the distorted screenshot to appear).

Example in (typo was indeed in the tweet) [Wayback/Archive] Excel Dictionary on X: “Are you ready for this Excel tip? Get ready to learn how to easily scew images. 🤯”: Read the rest of this entry »

oocities: Geocities Archive Geocities Mirror / The 90s Archive (1990s 2000s nineties) / The Early web

Posted by jpluimers on 2025/05/23

If I ever need old Geocities material then I should check back at oocities and other archival efforts as they have archived a truckload of it and (unlike the the Archive.org geocities arvhive) are indexed by public search engines.

Their archive home page is [Wayback/Archive] Geocities Archive Geocities Mirror / The 90s Archive (1990s 2000s nineties) / The Early web of which I quote a few bits:

  • Special Thanks goes to all the editors and webmasters who made this project alive by updating their old links every day
    from * geocities.com/*
    to *.oocities.com/*
  • oocities.com/org, geocities.ws, reocities.com, internetarchaeology.org, webcitation.org, deletedcity.net

Adding some domains from Yahoo! GeoCities: Archiving efforts – Wikipedia, these are publicly indexed archival sites that have parts of old Geocities content (part of which might be gone by the time you read this: web sites and their content become increasingly ephemeral):

Electronic Basics by GreatScott! – YouTube

Posted by jpluimers on 2025/05/22

[Wayback/Archive] Electronic Basics by GreatScott! – YouTube

At the time of writing these were some 60 videos each 5-15 minutes long in reversed order (#1 at the bottom, #61 at the top).

This means it is about 10 hours of watching time well worth it.

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:
