    I used to be really frustrated with how difficult to understand academic papers are, but after gaining enough knowledge, I'm now a little more sympathetic - it's really easy to tersely express ideas with complex language, simplifying them requires a lot more effort and is almost always more verbose.

      It would be nice if someone would keep a dictionary for all the field specific words that have quite precise meanings. That way ppl could reference that source instead of spending one or more paragraphs explaining a single word or notation. Or leave it as an exercise for the reader to figure out what something means.
      edit: before ppl explain the obvious fighting over the meaning of words this would produce, I know but a potato can dream.

      It may be field specific, but I honestly rarely encounter papers, that are complicated for the sake of being complicated, as some kind of intelectual voyeurism. Most of the difficulty comes from not knowing the field, which cannot be easily overcome I'm afraid.

    One from my brother:
    Code purpose: Every time list is changed, sort list.
    Problem: sorting list counts as a list change, producing infinite recursion.
    Solution: catch exception when hitting max recursion depth, assume list is sorted at that point, and continue from where you left off.

    • @EbonySeraphim
      @EbonySeraphim 8 หลายเดือนก่อน +3

      In the Java case, the debugger trap is useful as setting a breakpoint at the end of a function doesn't get triggered if the stack is being jumped/unwound. There may be advanced debugger features that can do this, but its much easier to combine basic debugger functionality with basic code and set a breakpoint on that line so you can examine what's going on as the exception is being thrown.
      A very similar (but not exact) reason to do this is if the caught exception is checked and you're just rethrowing an unchecked, or a different wrapped checked (ugh) exception.

      @@drewbabe
      If it hasn't changed it's necessary in Java to catch exceptions (elsewise the code will not compile), if you can't handle them you have to rethrow them.
      Thus the shown code is the only valid way in Java to escalate the exception upwards into runtime.
      It's not cringe in anyway, not every exception can be handled by a program, but needing to handle all exceptions leads to more safe code (defensive programming).
      I mean Rust does pretty much the same thing with an onEvent function instead of a catch block and people praise rust for this.
      Just because it's older way, doesn't make it worse.

      ​@@MrDavibu I don't see how putting it in a try/catch block would change anything in Java. I don't know if it was ever different, but when I've worked with Java the way it works is that a function can't throw an exception unless you include "throws Exception" (or some subclass of Exception) as part of the function declaration, and if you do have that included as part of the function declaration then you don't need to include a try/catch block even if something within that function throws an exception.

    Sometimes at work (in Go) we write functions that take a pointer to a boolean as a parameter, usually for a simple filter that has three states (eg: when requesting customer list get free users / premium users / all users). Certain higher level functions always need a particular list, but you can't just pass true because it needs to be a pointer, so I call it like this:
    true := true

    I had to spend probably an extra week of effort debugging an application on a customer environment the dev team doesn't have access to because the application is riddled with exception catches that throw new exceptions everywhere so you can never figure out the full story and even with full server logs w/ annotated context and testing results the dev team isn't always sure what happened.
    I kept mentioning that it was unfortunate I couldn't know what the error actually was because of it. But instead of getting better, there were more catch throw new added and added.

    Can someone explain what he is talking about with FizzBuzz and a map? I understand a map as either a hashmap like a typical Javascript object or the Array prototype function map where you iterate an array an pass a function to run that takes each item in the array as an argument. I was trying to look up solutions to FizzBuzz that use a map (or Array.map) and I can't seem to figure out how that would make it more extensible or scalable that using if statements.

    • @macctosh
      @macctosh ปีที่แล้ว +1

      You are overthinking it! I initially thought the same thing but realized there are referring to "map" ( iterate n times and transform each value ). FizzBuzz is so Trivial that it makes it difficult!

    • @altrag
      @altrag 7 หลายเดือนก่อน +3

      Its the hashmap one. It seems overkill if you're only dealing with 2 or 3 replacements, but it shows that you could design a routine that might take maybe 30 replacements if you wanted without having to write a giant stack of if/else.
      Of course you can do that with just a bunch of single ifs (not else ifs) as long as you're careful to only print a newline at the end of them all, but the next question (to drive you to the "correct" answer) would be asking how the replacements could be configured / passed into the method externally rather than hardcoded.
      If they push you to the map solution (one way or the other), and you're sufficiently familiar with your language's data structures to know how to deal with it (because they'll obviously tell you to suggest an answer yourself!), you can ask if the order of the words matters. In most languages the basic map structure is unordered and since that's (usually) not the goal of the exercise the interviewer might not have been thinking about it (not that they wouldn't understand the question of course, just that it might not have been in their head at the time so bringing it up might show an extra layer of thought about the problem).
      Of course FizzBuzz is so well known its unlikely they'll push all that hard. If its used at all anymore, it'll just be as a basic filter problem and they'll focus on something more relevant (and less likely to have just been memorized from any of the million examples online).

      @@DagarCoH As long as you're doing _something,_ its justifiable (well assuming the thing you're doing is not in itself useless of course). Wrapping an exception to change its type or provide additional context is an extremely common thing to do.
      Its the rethrowing of the same exception without taking any other actions that's pointless.
      Actually as written, its somewhat dumber than pointless - its taking a potentially typed exception and wrapping it in a generic Exception. Just as useless as rethrowing the same one, but with the added bonus of shunting the actual exception information (including the exception message) one level down the cause/innerException chain and making it that much harder to find the real cause within the stack trace.
      Someone higher in the comments suggested this might be done to intentionally blitz the stack trace in case it contained sensitive information. That's a valid thing to do (though not really the right way to do it), but the code in the video doesn't even accomplish that task in any meaningful way:
      - If the logger fails to dig into the cause/innerException chain, then you've not only lost the original stack trace but also the error message, making the log message entirely useless.
      - If it does dig into the cause/innerException chain then you've accomplished nothing other than to make your log output longer.
