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.”show more

Wanted to see if this held, but this was ruled an error on the second baseman, and in no way, shape or form, is this an error. This is an infielder racing into the outfield, and this is almost a terrific catch. If you can see the infielder’s full number as she is running into the outfield, that means it’s above ordinary effort. There have been quite a few shaky calls in this #WCWS (as per the usual sadly) but this isn’t an error. Even the announcer went with calling it an error, but this is 100% a hit.

Why Rust is overused right now Martin Odersky (Creator of Scala): "Right now, rust is actually overused because a lot of people push Rust for things higher up in the stack Where a garbage collector is fine, but essentially you still want to code without. And that is, for me, a bit an exercise in doing it intellectually just because you can I don't really think there's a big sense in it. If you have the memory for a garbage collector, you should absolutely use one, because it makes a lot of things simpler. So, yes, of course, if given enough brains, I can write code around and I can do that, but why should you? It can be much simpler."

Lots of folks wondering why the two plays to Oneil Cruz in the Pittsburgh Pirates at New York Mets game were recorded as hits. Here is the first one, and you can see he misjudges this line drive, and he comes in and then it sails over his head. MIsjudgement is NOT an error, so this correctly went down as a triple. Is it a ball that he needs to catch? Yes. Is it an error? No. An error is a physical misplay, and there is not a physicial misplay here. #LetsGoBucs #LGM

Scott on why conviction in an idea is dangerous as an investor but required as a founder: "From the investor seat, I don't think you want to be in love with an idea. That's a risky thing because you'll find a way to express that by investing and make some compromises on the team because you know this idea is just so good, its time has come. But if the team isn't there, 90% of the time it doesn't work. Then there's a whole thing can you swap out the team? But the whole Founders Fund thesis was always no, you need the founder to run the company. But on the company side, you have to be in love with the idea. It's not that rational to start a company. There's a lot easier, more comfortable ways to make money if that's the goal. So it's got to be about what the company is doing specifically. If you want to actually start a company, it better be something that you're really passionate about, or you think that the problem is really important."

Thomas Frank on Mikel Arteta: "I think it's a good example of a club that sticks to the process. I think six years, it's very rare you get that long in football. I also think it's fair to say that it took probably three seasons for Arteta. So the fourth season, that's where he competed, now he's in the seventh season. So he was really, really ready to compete in his fourth season. So he took over, then two full seasons, then the fourth one. So I think that's how you should see it. And then we know the difference between having ultimate success to win something or not is like this, and you need margins. But the process is the most important thing." 🤝

"Courage is far shorter in supply than genius." - Peter Thiel "One of the challenges in writing a book about entrepreneurship or teaching a class on this is that there is sort of no formula. And I think science always starts with a number two. It starts with experiments you can repeat, things you can do over and over again. But there's sort of a sense in which every moment in the history of business, every moment in the history of technology happens only once. The next Mark Zuckerberg will not be starting a social networking company. The next Larry Page will not start a search engine. The next Bill Gates will not be starting an operating system. And so if you are trying to copy these people, you're in some sense not learning from them. And so I think one of the really big challenges in teaching or writing about entrepreneurship is what can you say about being an entrepreneur at all when the key thing is always to do something new, different, that's not precisely been done before. And so the point of departure I start with in Zero to One is a somewhat indirect approach by asking a series of contrarian questions. The business question is, what great company is nobody starting? The more intellectual version of this question is, tell me something true that very few people agree with you on. And this is a fantastic interview question. It turns out to be quite a hard question, even when people can read on the internet that you ask of everybody who comes in the door, it still is a hard question. It's one of those unusual questions where if you know it's on the test, it's still hard. And it's hard not just because we sort of think that new things require brilliance or something like that, but because it's socially difficult. If I ask you that question, if you tell me something like the education system is screwed up or our political system doesn't work very well, those are true answers, but they're not actually good answers because all of us already know them to be true. The good answers are ones that are somehow uncomfortable that the person interviewing you does not actually want to hear. And I think we live in this world where courage is in far shorter supply than genius. And so it is sort of this, it is in a sense this problem of political correctness properly understood, is this very deep, very, very broad sort of a problem."

Ok, I'm not gonna lie, it's plays like this that make me question having my DMs open. It's obvious the folks asking me about this play in the Houston Astros and Texas Rangers game are either daily fantasy players, or gamblers, so I'll use this as an educational post. This is NEVER an error. This play where Brice Matthews is on the dead run, leaping to save a home run, and nearly making a SportsCenter Top-10 (this would have been No. 1) play is NOT an error. This is way, way, way beyond ordinary effort. An error is a dropping of the ball or a misplay in which the average fielder is expected to make the physical catch at that position, using ordinary effort. There is nothing ordinary about this. This is ALWAYS a hit. ALWAYS.

Justin Thomas was asked about his group getting put on the clock: "We just didn't really agree with it. ... The hard part to me with the whole pace of play thing is that you, there's so much that goes into golf and there's so much that goes into hole to hole in terms of, are you hitting it close, are you able to tap it in, or you have to mark it, stuff like that, to where, are you holding the group up or are you not, to where it's very hard to make that call. And we just didn't agree with it, to be honest. "But we got taken off, and a hole later we were caught up. So it kind of goes to our point of why we didn't think we should of, but it is what it is. It's a part of it."

🗣️ Mikel Arteta on if it's surprised him to see players sold for over £100m: "Yes, it has. I wouldn't have bet on that to be fair. But that’s the market, that means that there are clubs that are happy to invest or they believe that the valuations of those players are that, and that's fair. "In the end, the value of the player is what somebody can pay for you, and they've done it, so that's the value and it's the right one because someone is happy to sell and someone is happy to buy, and in the middle, a player is happy to move from one club to the other. So I think that's fair."

🚨 Elon Musk on Grok 3.5: "With Grok 3.5, that is about to be released, it's trying to reason from first principles. The focus of Grok 3.5 is to find the fundamentals of physics and applying physics tools across all lines of reasoning and to aspire to truth with minimal error. So apply kind of the tools of physics to thinking, and you know physics, if you violate conservation of energy or momentum, then you're either going to get a Nobel Prize, or you're wrong. We aim to get to truth with acknowledged error, but minimize that error over time. And I think that's actually extremely important for AI safety. So I've put a lot for a long time about AI safety, and conclusion is the old maxim that honesty is the best policy."

Why is Rust different than many/most programming languages? Alice Ryhl works on Google's Android Rust team, is a Rust language team advisor, and is a core maintainer of Tokio (the most widely-used async runtime in Rust) Timestamps: 00:00 Intro 04:09 Tokio: an overview 05:11 What Alice likes about Rust 12:48 Rust for TypeScript engineers 13:51 Moving from C++ to Rust 14:34 Memory safety 18:12 Garbage collection tradeoffs 21:46 Ownership, references, and borrowing 26:59 Unsafe in Rust 31:21 Crates and Cargo 35:55 Language design and RFCs 43:02 Building new features 46:30 Editions vs. versions 49:47 Getting paid to work on Rust 51:27 Contributing to Rust 53:03 Rust in the Linux kernel 55:45 AI use cases for Rust 1:01:35 Learning Rust 1:03:54 Book recommendation Brought to you by: • Antithesis – verify your system’s correctness without human review or traditional integration tests – and avoid bugs or outages. • Sentry – application monitoring software considered “not bad” by millions of developers Three things worth knowing about Rust: 1. Rust was designed to turn implicit failures into compile errors. Where other languages allow you to forget something, Rust makes an omission into a compilation error for things like null checks, uninitialized variables, or error propagation with the ‘?’ character. If you mess something up, it’s almost certain your program will not compile. If it does, at the very least you should see a lint warning. 2. Refactoring in Rust is safe and easy, thanks to the compiler. Alice: “I change a return type or struct field, then just fix the compiler errors until the compiler stops shouting. And then once I’ve done that, I’ve updated every place I need to update.” Rust’s focus on correctness makes refactoring it more straightforward than dynamically-typed languages and Java-style typed ones are to refactor. 3. “Editions” allow Rust to make breaking changes without ‘breaking’ anyone’s code. Rust editions (2015, 2018, 2021, 2024) can be mixed freely across crates. A library on the 2021 edition works seamlessly with a binary on the 2024 edition. This is how Rust evolves syntax (like adding async/await as keywords) without forcing an ecosystem-wide migration. Thanks a lot, Alice for this great discussion! And for your work on Rust.

EVERYONE needs to be aware how SIGNIFICANT the Wisconsin Supreme Court election is This election decides who controls The House of Representatives and Voter ID Elon Musk “The single biggest challenge, I think is actually just making people aware that there is this very important election. There's both the very important election for Judge Schimel as well as the deciding on, on adding voter ID to the Wisconsin Constitution institution, which is very, very important. So it's quite shocking ,you can sort of tell where voter fraud is happening, where they ban id, you know, like why would you ban, ID like in New York and California, it's like illegal to show idea at an election. Well, why would, I can't imagine why that would be the case…. So, two really important things is to ensure judicial integrity on Tuesday and then the voter ID thing It's April Fool's Day. So I think most people aren't aware, like I said, most people aren't aware that there is this important election, but there most people don't even know that there's an election at all. Or if they do, they aren't sure exactly when and where it is. — They don't realize just how important it is. They think it, it's, well it's just, you know, some kind of judicial thing that's not that important. But it actually, what they're doing, what's happening on Tuesday is a vote for the, the which party controls the U.S house of House of Representatives. That is why it is so, so significant and whichever party controls the house, to a significant degree controls the country, which then steers the course of Western civilization. So it's like, I feel like this is one of those things that, that may not seem that it's gonna affect the entire destiny of humanity, — it's a super, it's a super big deal. The fact that I'm here in person, like I'm not phoning it in. I'm here in person”

🚨WEIRD PLAY ALERT🚨 This is from tonight's Atlanta Braves at Miami Marlins game. This was originally scored a triple and an error, and almost immediately changed to an error on the right fielder and a throwing error on the center fielder. The original error on the rright fielder was for colliding with the center fielder as it looked like he had the ball. However, this was changed back to a triple and an error, as you have both fielders on a dead sprint back into right center. While yes, it might be a catch, the catch itself, and the play, is well above ordinary effort. The collision error isn't for this type of play, but a play where a fielder is situated where he can field the ball with ordinary effort and gets run into, with the ball getting knocked out, so this was changed after a review after the game but before stats were posted.
