  • I do not get why it would work in that case. I assume the scenario is someone with a bike coming, doing theft, then leaving with the same bike.

    Therefore there will be a period without bike, then a period with bike, then a period without bike again.

    Let’s assume there is no bike on the particular moment viewed. How do you know whether it occured before or after the theft? If you make the wrong decision, you get stuck on an endless binary search… Unless you take note at each timestamp where you made the decision, draw a tree of timestamps, and go back the tree if your search is fruitless but that’s much more complicated than what this post says.



  • There are techniques like abstract interpretation that can deduce lower and upper bounds that a value can take. I know there is an analysis in LLVM called ValueAnalysis that does that too - the compiler can use it to help dead code elimination (deducing that a given branch will never be taken because the value will never satisfy the condition so you can get rid of the branch).

    But I think these techniques do not work in all use cases. Although you could theoretically invent some syntax to say “I would like this value to be in that range”, the compiler would not be able to tell in all cases whether it’s satisfied.

    If you are interested in a language that has subrange checks at runtime, Ada language can do that. But it does come at a performance cost - if your program is compute bound it can be a problem


  • Why would you have to choose between tests and compiler checks? You can have both. The more you have the less chance of finding bugs.

    I would also add that tests cannot possibly be exhaustive. I am thinking in particular of concurrency problems - even with fuzzing you can still come across special cases where it goes wrong because you forgot a mutex somewhere. Extra static checks are complementary to tests.

    I think you can write “unsafe” code in Rust that bypass most of the extra checks so you do have the flexibility if you really need it.




  • I love that software. It’s so simple - no need for much clicking you can do a lot with just the keyboard.

    I love particularly how there is no bloatness. Creating a new task is as simple as pressing ctrl+a (or shift+a), typing the name and pressing enter. Creating a subtask is just pressing ‘a’ on the task and type the name.

    There is jira integration so I can import my jira tickets and make my own local subdivision in smaller tasks that do not need to be thoroughly described or shared. The status of the jira tickets can be updated from the app directly

    There is a pomodoro plugin that works well minor some bugs (don’t ever choose “close” when prompted to skip the break or go back to work)

    Wonder what did I do last week for writing a summary? Just look at the history in the app

    I really love it and can only recommend it for personal planning


  • Yes, getting into a new project is hard. Even when you do know the languages and frameworks it’s still hard because you have to get into the mini ecosystem that the developers of that project built. In companies there is usually an expected amount of time (days? weeks? Months? Varies on the project) where a new developer is not really expected to do anything major, just getting used to the project.

    I do not know if you are professional or hobbyist. But coding takes a lot of time, a lot of it is spent on just figuring out how you will code this or that feature ; then another bunch of time is spent debugging ; and finally, yet another bunch of time is spent integrating your new feature. That’s why it’s a whole job, and that’s also why you need a ton of free time to do this as a hobbyist.

    But the good news is that once you spent that upfront time to get into the project, you can code more efficiently (that is, get right to the features you want to make) and you will also spend a little bit less time getting into other projects because although projects are different, there is always some level of organization that remains similar. The more advanced you become, the quicker you can get into a “production” state where you can code right away thanks to spending less time figuring out how things work.



  • The Christian Bible’s Matthew 24 had a prophecy that is about to become historical-fact, in the coming decade.

    Here’s a decent version of it:

    https://www.biblegateway.com/passage/?search=matt+24&version=AMPC

    That bit around verses 15-20 is the pertinent area.

    Simply wait 1 decade, and see: if Israel still exists, as a country, in 2033, I’ll eat a hat.

    The nice thing about prophecies is that they can never be proven to be false. Indeed, one would have to examine the future to prove it wrong. Which is either impossible or unrealistic.

    Me too I can make a ton of prophecies and claim they will be eventually right. I will never be wrong.

    Let’s see. Let me prophesize that:

    • The US will cease to exist
    • We will encounter aliens
    • See where you are living right now? Eventually, it will be filled with lava.
    • See where you are living right now? Eventually, it will be flooded with water.
    • A giant comet populated with nyan cats will crash on Earth

    However, you can be sure that in 2033 I will come back in this thread and have you eat a hat. Marking the date and the link in my calendar. If lemmy is still alive, that is











  • It is literally part of Beehaw rules to be nice to each others, cf this excerpt from beehaw rules:

    If you aren’t nice, we’ll remind you to be nice. If you continue to be problematic, we’ll escalate from there, but it will be on a case-by-case basis. If your first reply when we ask you to be nice to each other is to tell us to “fuck off”, we will respond in kind.

    It is also part of the rules to not be transphobic, cf

    we simply do not tolerate intolerant behavior. Being explicitly racist, sexist, homophobic, transphobic, or bigoted in any other fashion is not tolerated here.

    If you find a transphobic post and you feel that you are unable to reply nicely, the correct course of action would be to report said transphobic post.

    If you are not content with this rule of “be nice” I’m afraid Beehaw is not for you
