lesshaste which color should comments be in in an IDE? I am trying to choose colors [04:59]
[twisti] dob1: .command is a setter. new ProcessBuilder is a constructor [05:00]
[twisti] lesshaste: download a theme or randomly pick your own [05:00]
lesshaste [twisti], I am color blind and am doing this for someone else so I really just need a name or color code [05:00]
[twisti] dob1: that being said, you may want to look at zt-exec [05:01]
[twisti] lesshaste: then just download a theme and be done with it [05:01]
[twisti] why are you changing the default color of things if youre colorblind and its not for you anyways ? [05:01]
[twisti] just leave them at whatever the IDEs default color is [05:02]
lesshaste I am making a presentation [05:02]
lesshaste where I want to have code [05:02]
lesshaste with comments in it [05:02]
lesshaste the presentation is for someone else [05:02]
[twisti] and youve decided that the default comment color is bad and can be improved by picking the random suggestion of a random person on irc ... why ? [05:02]
lesshaste #d4922f maybe? [05:02]
[twisti] but hey, if it helps you, #123456 [05:02]
[twisti] sure, #d4922f is fine too [05:03]
lesshaste [twisti], perhaps I will ask someone else :) [05:03]
[twisti] if someone gives you a suggestion for a comment color without knowing your theme and ide's other colors itll be worth about as much as #123456 [05:03]
[twisti] this seems like trolling, its hard to imagine someone being serious with a question like this, so im out [05:04]

Maldivia shan: sure you have the dependencies in your build classpath... but not your runtime classpath [08:31]
ScrambledRK shan: no, but it should at least point towards the missing class [08:31]
ScrambledRK Maldivia: I think its the other way around actually ... build is successful but tests/running doesn't work - also the stacktrace shows the BuildinClassLoader to fail ... [08:32]
ScrambledRK so I'd have guessed he is missing the classes at runtime [08:33]

dmlloyd I sure wish that HashMap and ConcurrentHashMap had a method like `T get(int hashCode, Predicate<T> equaller)` or something like that [10:40]
dmlloyd so you can look up a key without having to create an instance of the key [10:40]
Maldivia map.get(new Object() { public int hashCode() { return hashCode; } public boolean equals(Object other) { return equaller.test(other); } }); [10:42]
Maldivia D [10:42]
dmlloyd only works if they do equals the right direction [10:42]
Maldivia true [10:43]
dmlloyd also if it's stored in a TreeNode you're stuck... [10:45]
dmlloyd just tried to whip up an impl and it was dead simple - until I got to TreeNode [10:45]
Maldivia implement Comparable as well then [10:49]
cheeser ha. nice. [10:51]
dmlloyd that definitely won't work if it goes in the wrong direction [10:51]
cheeser it's true what They say about a layer of abstraction solving all problems. [10:51]
dmlloyd Comparable was a mistake IMO, they should have stuck with comparators [10:52]
dmlloyd same with equals() [10:52]
dmlloyd why make it possible to have an asymmetry like that [10:52]

vpathak [vpathak!~vpathak@c-73-178-141-116.hsd1.nj.comcast.net] has joined ##java [12:34]
sonOfRa and hashcode. If you override one of equals and hashcode, you should always override the other (and consistently!) [12:34]
dreamreal equals [12:34]
dreamreal See http://www.javaworld.com/article/2072762/java-app-dev/object-equality.html for an explanation (covers hashcode too) [12:34]
_lucifer and maybe implement a Comparator/Comparable (if you need ordering) [12:35]
birkoff what's the difference between equals and Comparable ? [12:39]
cheeser one is a method and one is an interface [12:40]
_lucifer exactly what the name suggests, equals is checking for equality and comparable is for saying greater, less or equal [12:40]
_lucifer yeah that too ? [12:40]
birkoff I have to override equals even if all I need is to check equality for all variables ? [12:43]
sonOfRa Yes. [12:43]
sonOfRa lombok [12:44]
sonOfRa sonOfRa, lombok is a tooling (compiler and IDE) plugin that removes boilerplate. For example, it adds getters, setters, equals, hashCode, builders, etc for you. Works in eclipse, intellij, netbeans, javac, maven, ant, etc. https://projectlombok.org/ [12:44]
sonOfRa Doesn't hurt to do it once or twice yourself (and by yourself I mean click on generate equals in your IDE) [12:44]
dreamreal birkoff: well, what does equality mean *in the general sense*? [12:44]
birkoff what would instance1 == instance2 or instance1.equals(instance2) do without alteration ? [12:44]
sonOfRa The same thing, unless instance1 is null, in which case the latter would throw NPE [12:45]
_lucifer check if the two variable refer to the same obbect [12:45]
birkoff _lucifer: so it wouldn't work for checking that the values of variables are the same ? [12:45]
sonOfRa It would not. [12:45]
_lucifer nope [12:45]
cheeser == is always a value comparison of the operands. in this case, it compares two reference values and that has nothing to do with object state. [12:46]
dreamreal birkoff: imagine a class describing state: class State { String name; State status; Timestamp ts; } [12:47]
dreamreal it's conceivable that you'd only care about name and status for equality, yeah? [12:47]

birkoff not sure what state means dreamreal . if my class only declares String and Float variables for example, would then == or equals be enough ? [12:59]
sonOfRa No. Just == is *never* going to compare the values inside your class. [12:59]
sonOfRa There is no sensible way for java to guess what you *want* to compare. [12:59]
birkoff but .equals would ? [01:00]
sonOfRa Yes, because you implement equals yourself, and tell it *what to compare* [01:00]
sonOfRa by default, .equals does the same thing that == does (compare if it is *the same reference*). [01:01]
sonOfRa But once you implement it, calls to .equals will do what you implemented. == will still compare reference equality. No operator overloading for ==. [01:01]

Maldivia wad: as said, all bitwise operators works on ints (or longs), doing it with byte will cause a lot of conversion -- at least in the bytecode, what the jit does it different [01:47]

dreamreal Paste the code (and any errors) in a pastebin where we can see it. See ~pastebin for options. Also see ~testcase for good examples as to how to help us help you quickly diagnose and solve problems. [04:46]
Maldivia yottabyte: remember process builder is not a shell, so if you list arguments like $HOME, it's that literal string and will not resolve to the env var [04:52]
ruurd In addition to that yottabyte remember that that kind of manipulation of the environment only influences subprocess of the one doing the manipulation. [04:53]
Maldivia (yes, taking a guess here, from something I saw earlier today, but not sure if it was you asking) [04:53]
dreamreal without code it don't matter, nothing to see here [04:53]
yottabyte I'm doing something like this: https://pastebin.com/jaWhRkfG [04:54]
Maldivia that should work [04:54]
yottabyte so when do do export OMP_THREAD_LIMIT=1; in command line and then run tesseract, it works, it's extremely fast. when I do it through java, it's VERY slow, because that OMP_THREAD_LIMIT isn't being respected. when I run it through command line without that export it's just as slow [04:55]
Maldivia yottabyte: create a simple script that call printenv and run that instead to verify if the env vars are there [04:55]
yottabyte so I want to run "export OMP_THREAD_LIMIT=1" in java explicitly [04:55]
dreamreal ... what Maldivia said [04:55]
dreamreal it may be that doing the command() before the environment() affects the sequencing [04:56]
yottabyte it doesn't, because I know the TESSDATA_PREFIX is being respected (it needs to be there) [04:56]
yottabyte call printenv when? [04:56]
Maldivia make a script file, like script.sh, and call that instead of tesseract [04:57]
Maldivia so you can see what the env for the subprocess is [04:57]
yottabyte should the script.sh include the tesseract command? [04:59]
Maldivia that's up to you... you just want to debug right now, right? [04:59]
dreamreal doesn't matter, you're looking for the contents of the environment to help I'mma let Maldivia carry this one [04:59]
Maldivia well, debug it then... you're trying to verify if the env vars are set or not right now, so verify that [05:00]
Maldivia a script with printenv in it was just the easiest way I could think of to verify [05:02]

squirrel if i can import and run a class in gradle (org.aspectj.tools.ajc.Main), how can i find out its classpath? i want to run it in a separate process. javaexec {} seems to work but i need to specify the correct classpath [05:43]
cheeser you should be able to reference that cp via a gradle variable. [05:43]
Maldivia squirrel: so you want to run the ajc tool ? [05:43]
cheeser something tied off the sourceset, iirc [05:43]

squirrel physically it's located in `C:\Users\me\.gradle\caches\modules-2\files-2.1\org.aspectj\aspectjtools\1.9.5\dfca1edabdca4f262d7f7c45cd8e11e6b88b9f6`, if i specify this it works [05:50]

acidjnk_new What do you think is best practice here: A REST service has a URL parameter, e. g. /customerInfo/{customerId}. Now that provided ID is wrong. Should it be a plain 404, not found, as opposed to if the paramter were in the body? Or in either case a 400 with a JSON error body? [06:39]

ruurd It's not a bad request because it matches your API amirite? [06:43]

squirrel ...i tried `new File(Main.class.getProtectionDomain().getCodeSource().getLocation().toURI()).getPath()` and this finds another `aspectjtools-1.9.5.jar` but this jar is different from the other one and doesn't work, causing `java.lang.ClassNotFoundException: org.gradle.internal.classpath.Instrumented` [06:46]
cheeser dear lord. [06:47]
cheeser still trying to exec from gradle? [06:47]
squirrel yup [06:47]
squirrel i wasted so much time on this i probably should just do what people on SO do and set up a hotkey to kill java processes [06:48]
tang^ why would anybody need a hotkey to kill java processes? [06:49]
tang^ wouldn't you just do it right? [06:49]
squirrel ?do it right?? [06:50]

wedr squirrel, by making the aspectjtools be a dependency library instead of directly loading it from a file. [07:14]

squirrel so maybe i solved it. i couldn't get the path of buildscript dependencies, but i had actual app dependencies. since i only need weaving in the debug build, i changed `debugImplementation 'org.aspectj:aspectjrt:1.9.6'` to `debugImplementation "org.aspectj:aspectjtools:$aspectj_version"`, had to do it for all subprojects though [08:47]
squirrel now lines 26-30 here https://bpa.st/6KSA work [08:47]
