What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

I've written a series of blog posts, in which I write a and a for arithmetic in . We explore the following topics in the series:

- Parsing arithmetic expressions to ASTs.
- Compiling ASTs to bytecode.
- Interpreting ASTs.
- Efficiently executing bytecode in a VM.
- Disassembling bytecode and decompiling opcodes for debugging and testing.
- Unit testing and property-based testing for our compiler and VM.
- Benchmarking our code to see how the different passes perform.
- All the while keeping an eye on performance.

The third and final post of the series that focuses on writing the virtual machine is now out: abhinavsarkar.net/posts/arithm

"Netanyahu confirms that Israel dropped "153 tonnes of bombs" in Gaza on Sunday, despite the ceasefire."

I'm sorry... wait. I may be a bit slow. I haven't got a fancy degree from MIT like Mr. Yahu, after all.

But how can you drop... 153 tonnes. of bombs. in one day... and still call it a ceasefire?

Also, exactly how many tonnes of bombs have Hamas dropped on Israel in recent days?

Also... *153* *tonnes* in *one* day.

How is this in any way sane? lemonde.fr/international/live/

The Extended Density (ED) 3.5-inch Microfloppy was an advance on the HD version, with improved oxide coatings that offered 2.88 MB of storage.

Introduced in 1991 on the NeXTcube, NeXTstation and IBM PS/2 model 57, it was too small an advance in capacity over the HD disk and never became widely used.

The ED disk had an identification notch on the right-hand side that was slightly higher than the one on the HD disk.

So, you may have seen that viral screenshot of Copilot in Excel summing 1, 2, 3 as 15. I am pretty sure it is faked.

I am a certified shoving-AI-in-our-things hater. I am also a librarian who, for my sins, uses Excel regularly. I shall lay out my proposal below. I will then mute this thread because I don't want to engage with AI boosters or anyone questioning whether I'm secretly a copilot lover (barf)

The claim:

Screenshot of a tweet by Zack Korman saying Copilot in Excel is a global financial crisis waiting to happen. The column A contains 1, 2, and 3 in what are apparently rows 1, 2, and 3. The function is =COPILOT("sum the numbers above") and the result is 15.

SCOOP: A man who worked on developing hacking and surveillance tools for Western defense contractor L3Harris Trenchant was notified by Apple that his iPhone was targeted with mercenary spyware.

The developer believes he was targeted after he was wrongly accused of leaking zero-days developed by Trenchant.

This may be one of the first documented cases of a zero-day maker being targeted with spyware.
