TIE Fighter Total Conversion in VR with a VR controller interactable cockpit is phenomenal. God I love this game, it's so cool re-visiting it like this.

having written about how banning web scrapers from a code forge i host made it usable again and saved ~60€/y in power bill, let me tell you:

you cannot fathom the offloaded cost of GenAI on small web hosts. it is a veritable distributed denial of service to the entire web. Every web admin sees it.

i built an entire x86 CPU emulator in CSS (no javascript)

you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS

Spent a whole issue of @aiandgames.com last month ripping these surveys apart.

Everyone from AI providers to GDC like to pretend they represent the voice of the industry. All of them talk out their ass and over-inflate their worth.

How I made a shooter game in 64 KB YouTube video by daivuk

Highly recommend this video, which is a super deep dive into the techniques used to create a 64kb demoscene-style '90s FPS:

This local Wolfdog joined an Olympic ski event and triggered the finish-line camera. This is Nazgul. He snuck into a cross-country skiing sprint this morning and raced the homestretch with some competitors before being escorted home. 14/10 someone get him a medal

TIMELINE CLEANSER!

You may never have heard C-3PO rap in an official Star Wars video, so it's time to remedy that. 🎡

A four panel cartoon of a small bird on a branch; the original images are from falseknees.com

Panel 1: "mov rax, rbx"

Panel 2: "add rax, rcx"
Another speech bubble appears, covering that one that says: "HELLO IT'S ME THE KEYBOARD"

Panel 3: A corvid appears next to the small bird; the new speech bubbles belong to it. It says "I HAVE AN IMPORTANT MESSAGE"

Panel 4: A closeup of the small bird with a frustrated look on its face. The corvid's speech bubble behind it reads, simply, "E".

You can test new tech ideas using the Seinfeld Test

Would the product eliminate the plot of an episode? (Google maps, cell phones, paypal, battery packs)

Good tech.

Would the product inspire new Seinfeld plots? (NFTs, AI chatbots, crypto currency, blindboxes, metaverse land sales)

Bad tech.

A round, light brown tablet made of clay with three lines of cuneiform scripts. Two rulings, or traced straight lines, enclose the writing. The photo also shows the sides of the tablet, including a few damaged parts.

May as well dive right in.

Did you know that dogs in ancient Mesopotamia also refused to drop the ball?

According to a Sumerian proverb, β€œThe dog understands β€˜Take it!’ It does not understand β€˜Put it down!’”

Everyday it gets harder to find a video to watch on YouTube while eating 














Brian may also be ready to throw the SM64 penguin

A section of the BBC News report on NYE Le Constellation fire with text as follows:

BBC Verify has verified two photos showing lit sparklers attached to bottles inside Le Constellation nightclub in the ski resort of Crans-Montana, Switzerland, shared online with claims they were taken around the start of the fire on New Year's Eve.

One image shows people holding several bottles in the air with lit sparklers attached and what appears to be a fire on the ceiling.

We searched for previous versions of this image online and no copies existed before yesterday. There are several details in the photograph which match older photos of the interior of the nightclub, including the bar, the wall decor and the pipework.

We ran the photo through four AI-detection tools, none of which detected AI manipulation but one said the image had been edited.

Running it through a digital manipulation tool showed no evidence of manipulation.

BBC are starting to detail their process for verifying images in their reports now. I fear we have truly entered the age of 'AI until proven innocent'.

Spent a while figuring out a crazy bug where save files kept getting overwritten randomly.

Turns out I had the following debug hotkeys:
Move backward: S
Crouch: Ctrl
Save: Ctrl+S

This is true and I was the only one on set excited about it (and playing the song on my phone to blank stares)

Some of you might know this story, but someone requested it as a reply to this thread, so I'll do that.

What you should know about me is that I've always had trouble with airport security, especially in the United States. I have 7 very Arabic names, and I travel a lot around the entire planet.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.

Say it with me now- placeholder assets are supposed to be bright and obvious so you DON’T ship with them.

Also it doesn’t matter if no ai-generated assets are in the final executable?? The rising sea levels aren’t gonna be like β€œoh well no one saw that so the climate change doesn’t count”

The thing about genAI is it's an amalgamation, a sanding down of many points of view.

So even when it's not lying, it's super mid.

Writing is about expressing a point of view, and that can be much stronger when you use a specific expert or source.

GitHub Actions Has a Package Manager, and It Might Be the Worst GitHub Actions has a package manager that ignores decades of supply chain security best practices: no lockfile, no integrity verification, no transitive pinning

Sounds like it might have been this one
