Everything About Bitflags: How to store up to 32 booleans in one value?

When I was younger and I was involved in reverse engineering communities and systems programming, there was this concept called bit flags. They were a standard way of storing a pack of true or false values in ... actually a single value - a function parameter, local variable or entry in some configuration. I found nothing fascinating about that back then and just used it on a regular basis, as every other engineer was. Long time after that and after shifting my focus to web development I just r

The maths you need to start understanding LLMs

The maths you need to start understanding LLMs Actually coming up with ideas like GPT-based LLMs and doing serious AI research requires serious maths. But the good news is that if you just want to understand how they work, while it does require some maths, if you studied it at high-school at any time since the 1960s, you did all of the groundwork then: vectors, matrices, and so on. One thing to note -- what I'm covering here is what you need to know to understand inference -- that is, using an

Trump Admin Raids Hyundai Construction Site as US Manufacturing Jobs Keep Shrinking

Almost 500 people were detained Thursday in an immigration raid at a new Hyundai manufacturing complex in Georgia. The massive raid highlights growing tensions between President Donald Trump’s anti-immigration policies, his tariff-fueled trade negotiations, and his promise to bring manufacturing jobs back to the U.S. “This was the largest single-site enforcement operation in the history of Homeland Security Investigations,” said Steven Schrank, a special agent in charge of the agency’s Atlanta

Major Amazon Prime Benefit Faces Crackdown Next Month

If you're using a friend or family member's free Prime shipping and you don't live in the same household, you might need to pay another monthly cost.

Should a Plug-In Hybrid Be Your Next Car? Here's How to Decide

"A plug-in hybrid is the gateway drug for EVs," says Amelia Dalgaard, an automotive expert known online as the Motorhead Mama. That's because plug-in hybrids address the range anxiety that stops some car buyers from going full-EV at first. Despite the growing popularity of traditional electric vehicles, not everyone is ready for a fully-electric car. And luckily, there's another option that's a good first step for many drivers: plug-in hybrids. Plug-in hybrids let you drive on battery power f

Gear News of the Week: Veo 3 Comes to Google Photos, and Garmin Adds Satellite Comms to a Watch

Google via Julian Chokkattu A few months ago, Google debuted a feature in Google Photos that lets you convert your existing photos into short videos using generative AI. These videos introduce slight synthetic movements to your stills, so a person may appear to slightly shift around in the frame, or a picture of your sleeping pup could gain a leg twitch. This week, the company upgraded this feature with its Veo 3 video generation model, which boosts the quality of the results. To play around w

Kennedy, Jr. has weathered ample family tragedy, drug and alcohol addiction, infection from an alleged brain worm, and a few sex scandals both minor and major — and now he's weathering condemnation from his own political allies that could presage a genuine crash out.

Speeding up Unreal Editor launch by not spawning 38000 tooltips

Speeding up the Unreal Editor launch by … not spawning 38000 tooltips? If there is one thing the Unreal Engine doesn’t suffer from, it is it’s lack of features. Over the past years it has been transformed from “just” a game engine into an ‘everything machine’. Games, Movies, Live-Content, VFX, Previz, even virtual fashion shows – it’s a behemoth of an editor with a multitude of tools, most of which are barely used or even known by many of its users. This multitude of features comes with some d

Developing a Space Flight Simulator in Clojure

Developing a Space Flight Simulator in Clojure In 2017 I discovered the free of charge Orbiter 2016 space flight simulator which was proprietary at the time and it inspired me to develop a space flight simulator myself. I prototyped some rigid body physics in C and later in GNU Guile and also prototyped loading and rendering of Wavefront OBJ files. I used GNU Guile (a Scheme implementation) because it has a good native interface and of course it has hygienic macros. Eventually I got interested

GOP Cries Censorship over Spam Filters That Work

The chairman of the Federal Trade Commission (FTC) last week sent a letter to Google’s CEO demanding to know why Gmail was blocking messages from Republican senders while allegedly failing to block similar missives supporting Democrats.
