Words about Arrays and Tables

July 30, 2025 2000 words about arrays and tables THEY'RE JUST FUNCTIONS I'm way too discombobulated from getting next month's release of Logic for Programmers ready, so I'm pulling a idea from the slush pile. Basically I wanted to come up with a mental model of arrays as a concept that explained APL-style multidimensional arrays and tables but also why there weren't multitables. So, arrays. In all languages they are basically the same: they map a sequence of numbers (I'll use 1..N ) to homog

Minnesota activates National Guard as cyberattack on Saint Paul disrupts public services

Minnesota Gov. Tim Walz has activated the state’s National Guard following a cyberattack on the state’s capital, Saint Paul. City officials have not yet disclosed the nature of the cyberattack, but the July 25 breach continues to disrupt city operations and some public services. Saint Paul is one of the largest cities in the U.S. with more than 300,000 residents, and is the latest in a list of major cities targeted by hackers and ransomware gangs in recent years. In a statement on Tuesday, Wal

A Nintendo Direct focused on third-party games is taking place on July 31

It’s almost time for another Nintendo Direct. A showcase of games from Nintendo’s partners that are coming to the Nintendo Switch and/or Switch 2 is set for 9AM ET on July 31 . The stream will run for around 25 minutes and you can watch it above when the time is right. This is a partner showcase, so you probably shouldn’t expect to find out release dates for Metroid Prime 4: Beyond or Kirby Air Riders here. Instead, we’ll hear about projects from third-party studios and publishers. Maybe we’ll

5 Linux distros for businesses looking to save money and protect their assets

AlexSecret/Getty Businesses around the world may not realize this, but they absolutely depend on Linux and open-source. Without those two pieces of technology, we wouldn't have nearly the services and sites we now enjoy. But Linux isn't just a good option for servers and technology stacks. Linux is also viable as a desktop operating system. Why? It's not only one of the most reliable platforms available, it's also very secure… and cost-effective. Yeah, that ol' bottom line will grab your atte

With iOS 26, Safari will counter one of the web’s most invasive tracking methods

Introduced for Private Browsing sessions in Safari 17.0, Advanced Fingerprinting Protection was also optionally available for regular non-private sessions. With iOS 26, it will be enabled by default. Here’s what that means. Starting with iOS 26 (as well as iPad 26, and macOS 26), Apple is flipping the switch on Advanced Fingerprinting Protection for all browsing sessions, not just Private Browsing. From Apple’s iOS 26 press release: “Browsing in Safari gets even more private with advanced fing

Mario Paint comes to Nintendo Switch Online and, yes, it has mouse controls

I’ve been wondering for a while what the killer app for Joy-Con mouse controls on the Nintendo Switch 2 might be. Sure, Nintendo Switch 2 Welcome Tour is fine as a tech demo (one that should have been a pack-in rather than costing $10) and Drag x Drive looks pretty interesting. Civilization VII has its fans as well. But the best use case for the feature yet could be a 33-year-old game that just hit Nintendo Switch Online. That’s right, the all-time SNES classic Mario Paint just joined the servi

What's the Difference Between Megabits and Megabytes? Here's What You Need to Know

Knowing how your home internet works may rely on understanding these two key terms: Megabits and Megabytes. Internet terminology is often maddeningly confusing. Case in point: Megabits and megabytes. Both refer to units of digital information, but the difference is subtle enough to cause plenty of confusion. Knowing the difference between the two terminologies can make all the difference when picking out an internet plan or figuring out how quickly you can download a file. Don’t worry -- we’ll c

Meta Is Going to Let Job Candidates Use AI During Coding Tests

Meta told employees that it is going to allow some coding job candidates to use an AI assistant during the interview process, according to internal Meta communications seen by 404 Media.

One of Nintendo’s most creative Super Nintendo games is now on the Switch

is a senior reporter who’s been covering and reviewing the latest gadgets and tech since 2006, but has loved all things electronic since he was a kid. Last night, Nintendo quietly added Mario Paint to the Nintendo Switch Online’s catalog of Super Nintendo games. Originally released back in 1992, Mario Paint was a unique SNES title, because although it included a handful of mini games, it was first and foremost a creative tool letting players draw, paint, animate, and even compose music using th

You Can Recycle Your Old Computers and Printers for Free. Here's Where to Take Them

It's somehow really hard to get rid of your old laptops, desktops and printers, even when it's been over a decade since you last plugged them in. But recycling old tech is easier than you think and can free up a lot of space in your home. A CNET survey found that 31% of US adults are still holding onto old, unused devices, including laptops, because they're unsure of what to do with them. The survey also found that 19% of respondents just toss old devices in the trash -- which is actually illeg

Yes, Starlink Is Now Much Cheaper: Here's the Catch

If you live in a rural or remote area, you likely already know how difficult it is to get a good internet connection. Most rural internet providers are devastatingly slow and typically expensive. Starlink's standard plan has become a lifesaver for those without decent rural internet options, but the hefty up-front cost of equipment, $349, and the monthly rate of $120 make Starlink an unaffordable option for many families in rural areas. Now, if you've been looking for a chance to try Starlink,

New Speed Test Data Reveals the Nation's Fastest Internet Service Provider

There's been a lot of talk about internet speed lately. From various company taglines -- "Don't take slow for an answer" -- to the latest news about Japan's internet data transmission record, it's all about the speed. Just recently, Ookla released its Speedtest Connectivity Report for the first six months of 2025, and AT&T Fiber topped the list as the country's fastest fixed internet service provider.

I Hate When Steam Drops for Maintenance, but Now I Know When to Likely Avoid It

You open Steam to boot up a game and get stopped by a warning saying Steam is down for maintenance. Frustrated, you wonder -- how long will this gameless purgatory last?

With some advance knowledge offered by Steam's owner, Valve, however, you may be able to avoid or reduce maintenance windows. In a support artic

Sam Altman Is Right: AI-Powered Crypto Scams Are Exploding

Finally, a profession that has managed to successfully integrate artificial intelligence into its workflow: Crypto scammers. According to a report from blockchain intelligence firm TRM Labs, crypto scams are up 456% over the last year, due in large part to the ability to produce deepfake audio and video clips with artificial intelligence tools—making good on OpenAI CEO Sam Altman’s recent prediction/warning that a fraud crisis is just around the corner.

Internet Archive joins federal library system as official repository for government documents

What just happened? Non-profit organization Internet Archive was founded by Brewster Kahle in 1996, as a digital library conceived to provide free access to digital knowledge via the internet.
