i’m not sure about the work on tooling

just a few weeks ago i was trying to work on a swift project in neovim and found the whole langserver experience pretty bad

and it’s way worse when working on swif ui apps, but i guess that’s more of an apple wanting you to use xcode thing.

i wish there was better tooling, i like the language, but i just switched to nim for my side project

I find the Swift tooling very lacking. There's no way to lint dead code, there no way to auto format the files exactly as Xcode would do it and tell the linter those rules so that it doesn't lint your auto formatted code. Xcode project files are impossible to edit except with Xcode and Xcode often has issues and I need to manually empty the build folder. These are just some of the issues I remember

Fun read!

Now that some bikes have electronic shifting, you can attack the bike itself. I wrote two blog post about how to downgrade the Shimano Di2 shifters and do a replay attack to remotely shift it. You can find them here:

Not that it would drastically change the conclusions, but do the numbers for "fund i" include the forms that say "fund ii" etc (by virtue of the fact that "fund i" is a substring of "fund ii" etc)?

pentamassiv · 5 months ago

It doesn't look like it does since "fund I" >> "fund II"

My theory is age. I get very few calls. Neither does my wife. My mother in law is called multiple times a day. I assume there’s some basic demographic data available out there and they’re targeting retirees because they know (statistically speaking) they’re an easy hit.

I think an important factor is also how long you had the same number. I switch numbers every couple of years because I get a new contract and moving the number to the new company is such a hassle. Over time you share your number with more and more companies and people who sell it or get breached.

My parents had their number for ~30 years. I never get spam calls or texts. They get one once a week or so (this is in Germany, we get a lot fewer of these calls).

Not being a programmer, I have a question.

Can any program be broken down into functions and functions of functions that have inputs and outputs so that they can be verified if they are working?

pentamassiv · 6 months ago

In theory you cannot even say for all programs and all inputs if the program will finish the calculation [0]. In practice you often can break it down but the number of combinations of input is what makes it impossible to test everything. Most developers try to keep individual functions as small as possible to understand them easier. You can use math to do formal verification, but that gets difficult with real programs too.

CRLite sounds like an elegant solution. Are there reasons why Chrome is not implementing it or do they just have other priorities?

Hey, I'm the author of the blog post. Thank you for submitting this. If you have any questions feel free to ask and please let me know how the writing was. It's one of my first posts so I'd like to improve

UPDATE: Two people from Anthropic recommended me internally and their HR department already rejected the application. They recommended me for jobs where you need more experience with AI, so I agree that I wasn't a good fit for those positions. Thank you for your recommendations anyways. That was very kind.

A number of other people contacted me with offers so it looks like there will be a happy end to the story :-)

I believe crates doesn't really allow that, partially so that people can't easily sabotage the supply chain like that :)

pentamassiv · 6 months ago

Correct, you cannot remove a version or the whole crate unless very specific criteria are fulfilled. You can "yank" versions. That prevents people from adding the version as a new dependency, but if you relied on it before it got yanked, your build will succeed.

I wouldn't delete old versions even if I could though. My goal is to publish a rock solid library that everyone can depend on and build awesome projects with
