[Wayback/Archive] How To Scale and Crop Images with CSS object-fit | DigitalOcean helped me to crop the picture in Florian Haas on Twitter: alias kubectl=”TZ=Etc/UTC kubectl”; You’re welcome.
The picture itself is 800 * 800 pixels (width * height), but the interesting bits are 400 * 200 around the center. Also it is a lot larger than I wanted.
So I embedded it using this HTML
<img class="alignnone size-full" style="width: 200px; height: 100px; object-fit: cover; object-position: 0 50%;" src="https://archive.ph/frSNu/0f0ebeeb5a4edf048577be89adb866344b303394.jpg" alt="" />
The width made it 25% the original size (because of [Wayback/Archive] object-fit value cover), and half the height so I had to move the [Wayback/Archive]object-position up 50%.
I found this via [Wayback/Archive] image inline css to crop top and bottom – Google Search.
That also found [Wayback/Archive] html – while display image crop Top and Bottom of image using css – Stack Overflow with an example at [Wayback/Archive] Edit fiddle – JSFiddle – Code Playground which is similar to the above solution.

For my link archive as this is environment variable override trick to override DLL loading is not just limited to executables shipping with Windows, but also with other products (likely: virus scanners that run privileged); another alternative is running a local process serving the WebDAV protocol.

Need to write a tool for this that sets/clears the ………… flag in the PE .EXE header.
Officially it is for this:
[Wayback/Archive] IMAGE_FILE_HEADER (winnt.h) – Win32 apps | Microsoft Learn
- IMAGE_FILE_UP_SYSTEM_ONLY
- 0x4000
|
The file should be run only on a uniprocessor computer. |
In practice, this sets the affinity to 1 single CPU core (which is kind of random, and could change each time you start the executable).
This is ideal for code that is known for causing trouble executing on multiple cores, or – more importantly – to disallow core-switching for programs that give best performance when executed on a single core.
Via: [Wayback/Archive] Thread by @0gtweet on Thread Reader App – Did you ever hear about IMAGE_FILE_UP_SYSTEM_ONLY flag in NtHeader->FileHeader->Characteristics of an exe file?

Interesting for both red teams and blue teams: [Wayback/Archive] Hijack Libs
This project provides an curated list of DLL Hijacking candidates. A mapping between DLLs and vulnerable executables is kept and can be searched via this website. Additionally, further metadata such as resources provide more context.

Het gebruik van Bitly is netjes vermeld: [Wayback/Archive] Privacyverklaring | Mazda
Bitly: URL-verkortingsdienst en linkbeheerplatform; dienstverlener: Bitly, Inc, 139 Fifth Avenue, 5th Floor, New York, NY 10010, USA; website: https://bitly.com; privacybeleid: https://bitly.com/pages/privacy.
Dat is belangrijk, want URL-shorteners zijn een risico op bijvoorbeeld:
- De daadwerkelijke doel-URL is niet op voorhand zichtbaar of duidelijk
- De doel-URL kan achteraf worden gewijzigd, dus waar je nu op uitkomt is niet noodzakelijkerwijs waar je in de toekomst op uitkomt
- Er kan user-tracking plaatsvinden op het niveau van de URL-shortener
- Ze worden veel gebruikt om malware te verpreiden (juist ook omdat de doel-URL makkelijk aanpasbaar is)
- In veel omgevingen worden URL-shorteners om bovenstaande redenen geblokkeerd

Somehow this post missed the schedule and for a long time I forgot to properly checked for “missed schedule” posts.
Back in 2021, suddenly systems with speedtest-cli threw a [Wayback/Archive] ValueError: invalid literal for int() with base 10: ” by tzwickl · Pull Request #768 · sivel/speedtest-cli after accessing the speedtest.net servers.
Around 7-8 April, 2021 the speedtest.net/speedtest-config.php XML configuration suddenly had changed the value for the XPath expression /settings/server-config/@ignoreids from being a list of integers into empty, see the archived files below.
