Javascript has a really cool operator called Nullish Coalescing & it can help you out! It's a logical operator that returns the value of the right side if it is null or undefined const cars = numberOfCars ?? 'incomplete data' If the numberOfCars is null we see incomplete data

Like this kind of tech content? Let me know! Thinking about creating a lot more of it. Breakdowns to make concepts easier to digest and understand. Make sure to share this with someone! Never know who might learn something new!

Haha I wish I had seen this before my technical interview yesterday! I got asked what Nullish Coalescing is?! I got it confused with optional chaining. Next time I will be prepared! Thanks for the quick and concise explanation!

Hacks rules. If you’re going through a tough time in life right now or if the news around the world is hitting you hard, Hacks is a show that can really help you crack a smile. At least it did for me. Jean Smart is a living comedic legend & we don’t talk about it enough, folks.

Flapping Airplanes co-founder Asher Spector explains why data efficiency is the greatest bottleneck to AI adoption: "To the extent that AI has been hard to integrate into the economy, I really think it's because models are much less data-efficient than humans. If you want it to learn a new task, or put it in a new vertical, it takes thousands of times more effort than it does to just tell a human what to do." "If you can make a model a million times more data-efficient, it's a million times easier to put into the economy. There's a ton of cool stuff that you can do in really data-constrained regimes. For example, whether it's robotics, or scientific discovery, or even something like trading, these problems have very limited data, and existing AI systems aren't quite as good at them as they are at other things. I think that learning to learn with less data is just tremendously valuable in all of these domains."

Bad data costs the US economy 3.1 Trillion dollars a year. What many fail to see is that bad data behind a secure firewall is still bad data. Incomplete or missing data affects industries into the trillions of dollars annually. Even worse, bad data can cost human life when faulty information is used in engineering, automotive, aerospace and countless other industries worldwide. Constellation Network $DAG has developed a distributed ledger technology to embrace the vision of a connected world, powered by big data, by creating the infrastructure to securely validate and protect one of the world’s most valuable resources.

In Yoshi's Island, it is possible to obtain an extremely corrupt object called a Null Egg, which has a variety of glitch effects. One of them is that taking the Null Egg into the Naval Piranha battle will cause the boss to assume a psychedelic, color-changing rainbow appearance.

This would be hilarious if it wasn't so heretical. Danielle Daniel Haqiqatjou claimed in one of his recent streams that the Shia don't believe that the Quran has been altered or that it's incomplete. His source? A chat with the known Shia zindiq Ammar Nakshawani. Meanwhile, Nakshawani confirms Shi'i belief that the Quran is incomplete. We seek refuge in Allah from such heresies and those who whitewash heresies.

The OSI Model is like a map for how data moves across networks. While some argue that it's out of date, if you are studying for the Net+ or CCENT certs, you should still understand how it works.

Reporter: “If the jobs data is not reliable, should Americans trust the inflation data?” Leavitt: “The jobs data has had massive revisions. We want to ensure that all of the data…coming out of the BLS is trustworthy and is accurate, which is why the president has restored new leadership at the BLS.”

You spawn ridablehorse2 on AUX02 & it can swim while you ride it in deep water. This is really cool BUT if you run out of stamina the horse will die. However right now you can sort of feed it to stay alive but it's not consistent. #Rust

🚨 Jensen Huang says everyone panicked about the AI data when MOST training data was never REAL to begin with. Ilya Sutskever told the industry pre-training was over. "Ilya said, 'We're out of data,' or something like that. 'Pre-training is over,' or something like that," Huang says. "The industry panicked, you know, that this is the end of AI." "And of course, of course that's obviously not true. We're gonna keep on scaling the amount of data that we have to train with." "A lot of that data is probably gonna be synthetic." That's where the panic came from — synthetic data sounds like cheating. "Most of the data that we are training, that we teach each other with, inform each other with, is synthetic." "It's synthetic because it didn't come out of nature." "You created it. I'm consuming it. I modify it, augment it, I regenerate it, somebody else consumes it." The textbook in your hand is synthetic. The post you're reading is synthetic. The lecture you took is synthetic. Nature didn't make any of it. Humans did. AI just learned to do the same thing — faster. "Training is now limited by compute," Huang says. "Data is now limited by compute." The data wall wasn't a wall. It was a mirror. If you're new here, follow @AiEvolutio for the latest on ChatGPT, Claude, and the AI tools shaping how we work and create. — Jensen Huang ( NVIDIA ), NVIDIA CEO, on Lex Fridman's ( Lex Fridman ) podcast

Kevin Hassett: "The data can't be propaganda. The data has to be something you can trust, because decision-makers throughout the economy trust that these are the data that they can build a factory because they believe, or cut interest rates because they believe. And if the data aren't that good, then it's a real problem for the US."

I’m very excited that College Football is going the way of the NFL where any given catch can be determined to be incomplete if you slow it down 10x and look for the ball moving a single centimeter This is a catch. And it’s gross that it was overturned

In Rust, error handling is opt-out, not opt-in. Alice Ryhl (Rust for Android at Google, Rust language advisor & Tokio maintainer) explains: “The other thing I think is quite good is error handling. So on one hand, Rust doesn't really use exceptions, so it actually returns the error as a value. So you return a value that's, using an enum, either the result or the error. And the way this is done is that there's an operator `?` - so you write: my_function and then a question mark at the end - which means if this function fails, return the error. So it's really easy to handle errors but it's not serial characters like it is with exceptions, so it's explicit. On the other hand, if you forget to put the question mark, that's a compilation error. So you have to check it, and of course you can also have it manually, but the point is it's this idea of there are these things where you write some code and there's some implicit error condition you didn't think of and now you just took down your server or something.”
