A Lisp adventure on the calm waters of the dead C (2021)

A Lisp adventure on the calm waters of the dead C I will use a C-like language throughout, with substantial liberties in its syntax, and I will try to answer "what if" and "how" questions regarding the implementation of some new features that actually cannot be implemented in C due to its limitations.

ZDNET's key takeaways This is a great value tablet, with a 12-inch display and running Android 15.

Judge rejects Meta's claim that torrenting is “irrelevant” in AI copyright case

Now that Meta has largely beaten an AI training copyright lawsuit raised by 13 book authors—including comedian Sarah Silverman and Pulitzer Prize-winning author Junot Diaz—the only matter left to settle in that case is whether Meta violated copyright laws by torrenting books used to train Llama models. In an order that partly grants Meta's motion for summary judgment, judge Vince Chhabria confirmed that Meta and the authors would meet on July 11 to "discuss how to proceed on the plaintiffs’ sep

WhatsApp Deploys AI, for Those Incapable of Comprehending Straightforward Messages From Their Friends and Family We are once again asking: who asked for this? Summary Judgment WhatsApp is now offering AI summaries of text threads for those too lazy to read through their messages themselves.

Senators reintroduce App Store bill to rein in 'gatekeeper power'

Update: Apple has responded to the reintroduction of the bill with a statement provided to 9to5Mac. See full statement below. The App Store is back under scrutiny from lawmakers in Washington. A bipartisan group of senators has reintroduced the 2021 Open App Markets Act, a bill aimed at curbing the gatekeeper power that Apple and Google hold over the so-called “mobile app economy.” Here’s what they’re going for. If passed, the legislation would effectively force Apple and Google (who are not s

You've Probably Hit Your Protein Goal: Here's What Experts Think You Need Instead

There's plenty of healthy eating and workout trends that come and go over the years, but one topic seems to come up again and again: Protein. Contrary to what you may be hearing on social media, you're probably already getting all the protein you need. Similar to counting calories, the protein goals trend has gotten out of hand, causing people to buy expensive protein bars, shakes and slabs of meat. According to Dr. Andrew Freeman, a cardiologist at National Jewish Health in Denver, it's actual

NASA tested a new SLS booster that may never fly, and the end of it blew off

NASA's Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights. But chances are low the Space Launch System will making it to nine flights, and if it does, it's questionable if it would reach that point before 2040. The SLS rocket is a core piece of NASA's plan to return US astronauts to the Moon under the Artemis program, b

How much slower is random access, really?

by Sam Estep, 2025-06-23 You may know that, because your computer has different caches (L1, L2, L3...), and memory operations operate on cache lines of about 64 bytes each, you should write programs that exhibit locality to get maximum performance. L1 L1 L1 L1 L1 L1 L2 L2 L2 L2 L2 L2 L3 RAM (Disk not shown, of course.) But how well do you understand this idea? For instance, let's say you have an array of floating-point numbers, and an array of all the indices of the first array. You have a p

Memory safety is table stakes

The past few years has seen a massive success story for systems programming. Entire categories of bugs that used to plague systems programmers—like use-after-free, data races, and segmentation faults—have begun to completely disappear. The secret to this new reality is a set of systems programming languages chief among them Rust—whose powerful type systems are able to constructively eliminate these kind of bugs; if it compiles, then it’s correct … or at least, will not contain use-after-free or

Mortgage Rate Forecast Clouded by War Moves, Tariffs and the Federal Reserve

Buyers should keep an eye on the possibility of rate cuts in the next few months. Tharon Green/CNET The housing market is hardly immune to political and economic volatility, yet mortgage rates have been eerily calm over the last period. Since the spring, the average rate for a 30-year fixed mortgage has moved in a mostly narrow range around 6.8% and 7%. Mortgage rates were expected to gradually improve in 2025. However, the Trump administration's inflationary tariffs, deficit spending and geop

Judge: Pirate libraries may have profited from Meta torrenting 80TB of books
