This is an excellent read. I was expecting a Rust rant but was instead treated to a very well thought out article about how to write more defensive code in Rust. Highly recommended.

When writing codecs in Rust I found the Iterator trait (and all its provided methods) to be very useful for avoiding panics relating to out of bounds indexing into arrays. It also tends to generate very efficient code since bounds checks ar

During The Plague of 1665 in London they culled 200,000 cats thinking that they were the root cause. It turned out that the rats were the cause and cats were their natural predator at the time. So they made things worse. https://

There are many cheap ultra low power microcontrollers that can keep a time clock going and a small amount (say 32KB) of ram. 30 years on a coin cell. Pair that with a Bluetooth low energy transceiver to automatically transfer the data when

Admittedly I ended up building a board with a microcontroller rather than a microprocessor because I could interface with the modem over spi too. However, this YouTube channel was great to work through: http://www.youtube.com&#x2

Knee jerk reaction about the ambulance service behaviour and general cyclist safety aside, 100k in medical expenses and a 1m lawsuit for a broken nose and other “unspecified” injuries is just mental.

If you learned Rust first but find yourself reading a lot of C then this is also a good thing to read because of the parallels it draws with the languages.

Very impressive! Looks like it could be used to practice hair cutting and to perhaps come up with some new styles. It’s a shame that safari on iPhone is so crippled. Webgpu support in combination with the depth camera could turn the casual

I believe that you would use dotnet nano for something like that. I used it (or some previous version of it) once many years ago and was very impressed with the productivity and ease of use it offered. Ultimately the lack of community surro

You’re right, whether or not the integers are signed has nothing to do with the issue above. Unsigned integers have the same issue. Here is an example for signed integers. These represent zero time but have different representations in memo

by davidhyde 2y ago
I think it’s important to be explicit about whether or not signed integers are used. From reading the document it seems that they may be signed but they could not be. If they are signed then you could have multiple bit strings that represen

My personal take on this subject is that Rust turns experts back into beginners and some devs react with hatred because of the fear this induces. For me it was the opposite. I was getting bored with my industry and thinking of a move to som

OP said less than 40MB. You can build Slint binaries targeting embedded devices. So a few hundred KB for a small application. Still arguably too much space but gui frameworks like slint use a domain specific language that generates more ver

Thanks, I probably shouldn’t be commenting on an LLM article if I don’t even know what a gold answer is! Oh well.

It’s problematic because the LLM is describing another person’s scan and not the one presented to it. It should at least present the other scan as workings and the percentage difference between the two. Finding a similar looking scan is ver
