bendem is there some consistent cross platform way to reserve an unused port at application start so that it can be used later on without any risk of it having been taken by another program? [06:10]
Diablo-D3 bendem: yeah, use it. [06:10]
bendem I have been trying a few options, but I always end up with a port that's been taken at some point [06:10]
Diablo-D3 also, stop using common ports [06:10]
bendem Diablo-D3, it sometimes gets used between the time I check I can bind to it and the time I bind to it [06:10]
bendem which is literally a few ms [06:11]
Diablo-D3 that seems unlikely that you're cycling through random ports that fast [06:11]

bendem let me show what I tried [06:11]
sbeex haha ok regarding flyway... in order to get the things to execute you have to pay a license... hmm [06:12]
bendem [06:13]
bendem bendem's title: " by bendem" [06:13]
bendem Diablo-D3, ^ [06:13]
bendem sbeex, not for the community edition [06:13]
Diablo-D3 bendem: because you're not quite doing it right [06:14]
deebo we've used springs SocketUtils and new ServerSocket(0).getport just fine [06:15]
bendem to provide more context, the java app checks for an available port and then passes it to another process to bind to that port [06:15]
sbeex bendem: what do you mean ? I can't see it with the community edition afaik [06:15]
deebo no problems in a busy CI server running tests on random ports [06:15]
Diablo-D3 bendem: yeah, dont do that [06:15]
Diablo-D3 socket = new ServerSocket(0); and then dont close it. [06:15]
bendem Diablo-D3, then the application I start can't bind to that port [06:15]
Diablo-D3 I think you have your logic in reverse [06:16]
Diablo-D3 the thing that needs to open the socket should _open the socket_ [06:16]
bendem no can do, the thing I'm starting needs the port as a parameter [06:16]
Diablo-D3 from what I can tell, the thing that doesnt need to open it, opens it, sees what port that is, and then tells other app to open it on that port [06:16]
Diablo-D3 so, open, record, close, elsewhere, open, cant open [06:17]
esro [esro!] has joined ##java [06:17]
bendem there is no way to tell that application to choose a unused port [06:17]

adder [adder!~adder@gateway/tor-sasl/adder] has joined ##java [06:18]
yawkat i dont believe this is possible cross platform [06:18]
Diablo-D3 lets widen the angle a bit [06:18]
Diablo-D3 generally, on any OS, including windows, you have two rules [06:18]
Diablo-D3 dont select a port above 10000, apps that open transient connections use lots of space here [06:19]
Diablo-D3 dont select a port below 1024 due to *nix security rules (and NT mostly enforces it too due to bsd sockets) [06:19]
Diablo-D3 without knowing anything about your app, choose a port that is between the two, and stick with it [06:19]
bendem ok, let's go the other way around [06:20]
Diablo-D3 Windows and OSX both have complex behavior on trying to open a port that was just open when its above 10000 (to prevent trivial impersonation attacks that exploit TCP weirdness) [06:20]
bendem I want to start a postgresql embedded instance in my tests, I'm getting clashes with the current method ( in the paste). [06:20]
OnceMe how can I find in page content, <script type="text/javascript">some input from user</script> and escape special chars "some input from user"? [06:20]
bendem the test suites start a postgresql instance per test (about 100 different ones) and I generally have one or two clashes if I have two builds in // [06:21]
bendem the test suites are themselves parallelised, so I can have up to 8 database instances trying to start at the same time [06:22]
Diablo-D3 maybe Im wrong, but doesnt postgresql embedded just use postgres.start(hostname, port, etc)? [06:23]
bendem yes, and that's that port parameter that causes trouble [06:23]
Diablo-D3 so keep trying start until it returns a started instance [06:24]
bendem there is no way to know [06:24]
Diablo-D3 yes, there isnt [06:24]
Diablo-D3 literally keep trying until it opens successfully [06:24]
Diablo-D3 increment, try again [06:24]
Diablo-D3 and then when successful, return that to the test that needs to call pg [06:25]
Diablo-D3 your flow of communication is simply backwards [06:25]
Diablo-D3 pg needs to tell test what port it has, not test tells pg what port to use [06:25]

surial bendem: you're firing up an entire postmaster -per test-? Holy cow. [06:46]
bendem surial, yup [06:46]
bendem it's actually pretty fast (< 2 seconds), the slow part is spring, not postgresql [06:46]
Addax bendem: ... why per test? [06:46]
bendem because I can [06:47]
Addax But... spring would be a once per jvm thing too, or should be [06:47]
bendem and it's not per test, it's per test suite, generally has 4-8 tests in a suite [06:47]
yawkat for integration tests, why not [06:47]
surial bendem: I don't have real answers so I'm going to try to appear useful by giving you answers to different questions. Feel free to tell me to shut up already if I'm going over ground you covered long ago... [06:47]
bendem Addax, no, because if I rebuild the spring context in the same fork, memory leaks and the tests OOM [06:47]
surial bendem: [1] can't you just create an entirely new DB every time? Also, I believe the postgres-ng thingie (different, external JDBC driver for postgres) has a full reser thing going on... [06:48]
surial bendem: [2] Sounds like you are already doing it, but I've programmed my webserver to hit a special magic URL which tells any already running webserver there to pack it up, then it tries to open the port for a while every quarter second until it's there, then it starts. (this is obv. for dev, so I can just start the server without having to bother with hard-terminating the old one)... a similar schtick could work here, no? [06:49]
deavmiLaptop [deavmiLaptop!~deavmi@] has joined ##java [06:49]
surial Diablo-D3++ huh, wow, that 'stop opening a port that was just closed' trick, never heard of it. I run my dev servers below 10k, never knew 10k was a magic border of sorts. [06:50]
surial diablo-d3 has a karma level of 12, surial [06:50]
bendem you are all cute. I understand that the current way is not efficient, we have plans to rework it in the future, yes we thought of different solutions, yes, they are nice ideas, sure it would be nice and faster. BUT, we already have a solution that works, the slow part is not postgresql so no it's not on the top of the todo list, budgets, pressing matters, the classic problems [06:51]
Addax bendem ++ [06:52]
Addax bendem has a karma level of 50, Addax [06:52]
Addax dismissive yet accurate, I like it :) [06:52]
surial Hey, bendem called me cute. I count it as a win! [06:52]
bendem currently, I want to fix the port binding problem because THAT is the problem at hand, I would love to rework the whole thing, but budgets [06:52]
conan [conan!] has joined ##java [06:53]
bendem I'm looking at Diablo-D3's idea to start the whole postmaster multiple time until it actually started correctly, maybe I'll look at creating new databases inside the same postmaster if it's easy [06:53]
surial bendem: you said strategy #2 in basically doesn't do it: It tells you a port is free when it is not. [06:54]

surial bendem: right? [06:54]
progart [progart!~kamee@] has joined ##java [06:54]
bendem surial, my guess is that two suites find the same available port [06:54]
surial oh, you're running em in parallel? [06:55]
surial except, PORT is no doubt an AtomicInteger? [06:55]
bendem yes, as I said, there can be up to 8 postgresql instances trying to start [06:55]
bendem yes, but they start in different forks, not threads [06:55]
surial assuming it's the same AtomicInteger instance (maube it is not; various test frameworks intentionally attempt to...) right, that. [06:55]
yawkat bendem: the OS should not immediately reassign a port [06:55]
surial trivial plan: init the PORT variable with: 1050+rnd.nextInt(8000) [06:56]
yawkat (assuming you use the serversocket trick) [06:56]
bendem yawkat, that was my hope when I wrote the original port choosing, but I still get clashes [06:56]
bendem surial, why did I not think of that... [06:56]
surial final AtomicInteger port = new AtomicInteger(1050 + rnd.nextInt(8000)); // sidenote: Shouldn't mutable final things be lower-cased? [06:56]
bendem hits head against desk [06:56]
surial See, I'm cute AND smart! [06:57]
Diablo-D3 wait, you were trying to start these in parallel? [07:00]
Diablo-D3 no wonder its not working [07:00]
Diablo-D3 you're searching the space the same way at the same time [07:00]
bendem yeah, I know it's dumb [07:00]

[twisti] but i was under the impression quarkus was something for kubernetes, which im not using (im a docker person) [08:40]
dmlloyd you can use it with docker though you have to DIY it a bit at the moment, but our integration tests are currently using Docker for some stuff [08:41]

Addax "occupies some engineers at red hat" [08:43]
[twisti] my REST api will have considerable (cross session) state, so im not sure a serverless approach makes sense for me [08:43]
Addax there's nothing in any of those that would invalidate shared state [08:44]
yawkat hah [08:44]
yawkat yawkat's title: "Maven Repository: org.hibernate hibernate-core 5.4.2.Final" [08:44]
yawkat they call LGPL "library gpl" [08:44]
Addax it hasn't been called that for a long time [08:44]
[twisti] Addax: i was under the impression that the serverless approach is one of multiple, sort of ephemeral JVMs that are scaled up and down depending on load [08:45]
yawkat oh it was renamed? [08:45]
tachyon_ parted the channel: [08:45]
Addax yawkat: yeah, years and years ago [08:45]
yawkat ahh [08:45]
[twisti] how would one go about sharing state between those, other than through expensive serialization and transfer ? [08:45]
Addax then the FSF realized that "library gpl" made it sound attractive, so they renamed it such that morons would think "oh, I'll go with the good one, the GPL, instead" [08:45]
Addax [twisti]: that's... not what those frameworks are, although you could use them that way [08:46]
yawkat yea i figured as much :D [08:46]
[twisti] Addax: could you describe them better ? honest question [08:46]
Addax dropwizard [08:46]

deavmiLaptop [deavmiLaptop!~deavmi@] has joined ##java [08:47]
Addax [twisti]: oh. Well, sure, I don't have a problem with your definition, just the assertion that using any of the things I mentioned meant going serverless [08:47]
Addax none of those things are AWS lambdas [08:47]
Addax yawkat: I have a massive bias against all FSF licenses :/ [08:48]
[twisti] Addax: the serverless thing was in reference to quarkus [08:49]
Addax quarkus isn't necessarily a serverless thing either, though... I think? [08:49]
Addax I haven't used quarkus yet, not enough time to play with it, so I'm going off of first impressions [08:50]
[twisti] my first impression was that it was a kubernets/container management thing, and multiple containers kind of scream problem with shared state [08:50]
[twisti] not that that isnt a perfectly valid setup for the right application [08:51]

Diablo-D3 so what does quarkus actually do [09:02]
Addax what does dropwizard actually do [09:03]
Addax or spring boot [09:03]
Diablo-D3 let me try again [09:03]
Diablo-D3 why would I use this instead of those [09:03]
cheeser builds smaller, memory efficient runtimes with low start up and latency times [09:03]
Addax much different question, indeed [09:03]
cheeser we can also build native images from your application to run $anywhere [09:04]
LaSombra a/quit [09:04]
cheeser never gonna give you up! [09:04]
Diablo-D3 but as usual, sombra let us down [09:04]
cheeser it's a real sombra moment. *takes a moment of silence* [09:05]
Addax we need a moment of silence from that joke. So, cheeser: SILENCE [09:05]
Diablo-D3 that was not the play of the game [09:06]
nullbytes [nullbytes!18bb7a88@gateway/web/freenode/ip.] has joined ##java [09:08]
nullbytes Why is double precision different in Java vs C++? In C++, 16.188 + 1.16436 = 17.35236 but in Java it's 17.352359999999997 [09:08]
Diablo-D3 thats the same answer. [09:09]
canton7 Are you sure it's not just the way that they're printed that's different [09:09]
gbobby nullbytes: did you declare it strictfp? [09:10]
yawkat strictfp has no effect anymore [09:11]
gbobby (apart from the fact that the C/C++ implementation need not be IEEE 754 compliant, afaik) [09:11]

yawkat actually, maybe thats not in yet [09:11]
yawkat but it should have no effect on + [09:11]
Diablo-D3 ieee754 doesnt seem to be an issue unless you're calling x87 ops [09:12]
yawkat its probably some tostring issue tbh [09:12]
conan [conan!] has joined ##java [09:12]
Diablo-D3 it really is just a printing issue [09:12]
gbobby the C/C++ standards do not state what the exact properties of the 'double' type are [09:13]
dmlloyd it's just default rounding yeah [09:13]
nullbytes It's 17.35236 with C++ printf("%lf", num) and ActionScript trace(num) but 17.352359999999997 with System.out.println(num). [09:13]
Addax nullbytes: so there you have it [09:13]
Diablo-D3 nullbytes: if you dont understand our discussion, floating point is inexact [09:13]
dmlloyd print it in hex on both platforms to get the exact answer [09:14]
Diablo-D3 17.352359999999997 is closer to the actual literal answer [09:14]
Diablo-D3 17.35236 is what you expect it to be [09:14]
Diablo-D3 theres a bit of magic going on to get the human readable one [09:15]
mohsen_1 [mohsen_1!uid289573@gateway/web/] has joined ##java [09:17]
Addax "abraaaaaa*rounding*" [09:17]
dmlloyd it's not imprecise or inexact it's just not a decimal number [09:17]
dmlloyd it's binary [09:17]
dmlloyd binary can't represent fractions other than 1/(2^n) [09:18]
nullbytes Is it just a difference with the human readable form or will there be different results if the same calculations are performed in Java vs ActionScript? For example will Math.floor be different? [09:18]
dmlloyd including 1/5 [09:18]
Diablo-D3 a wizard is never late, nor is he early, he arrives precisely when he means to [09:18]
Diablo-D3 nullbytes: assuming both are ieee754, they're the same answer [09:19]
Addax nullbytes: you'd have to test, actionscript may preserve different properties of floating point [09:19]
Diablo-D3 one just got printed differently [09:19]
supernov1h [supernov1h!~supernova@] has joined ##java [09:20]
gbobby there are side effects if you (mis)use float/double for calculating e.g. something like the price of items in a business applications [09:21]
gbobby good luck with the rounding if you do [09:21]
gbobby that's why mainframes commonly have decimal maths implemented in hardware [09:22]
ExtraCrispy [ExtraCrispy!~ExtraCris@gateway/tor-sasl/extracrispy] has joined ##java [09:22]
dmlloyd commodity hardware also does in many cases [09:23]
Diablo-D3 you could do Double d = 16.188 + 1.16436; System.out.printf("%f %a\n", d, d); [09:23]
gbobby I think the Intel CPUs have some, IIRC .. not sure what exact implementation [09:26]
freeone3000 Intel CPUs had them in x86, but they got cut for x64 because they were slow and nobody used them. [09:26]
Diablo-D3 I think that was part of the fpu, thus "gone" [09:26]
Addax that's because when Intel had them the industry thought that the money didn't matter, there'd always be more more more more. And now we have AOC showing us that numbers not mattering has migrated. [09:27]
forgottenone [forgottenone!~forgotten@] has joined ##java [09:27]
freeone3000 ...what? [09:27]
nullbytes It's okay as long as it's just a difference in the way the numbers are printed. I am porting an ActionScript program to Java and I don't want the calculations to be affected. [09:27]
Addax I'm bitching pointlessly and largely inaccurately for the sake of memes. [09:27]
dmlloyd "shitposting" I believe the kids call it [09:28]
Addax oooo! [09:28]
freeone3000 okay they existed from the dawn of floating point until like 2006. they got cut with x64 along with bcd and the ability to rotate binary numbers, because C didn't do these things and no other processor did these things so nobody bothered doing these things on intel so they're disabled with the x64 ISA to get back some one-byte opcodes for ... I'm sure they'll use them for something. [09:28]
Addax feels young again :) [09:28]
Diablo-D3 freeone3000: Im saying they existed physically in the x87 [09:28]
freeone3000 Diablo-D3: They still exist physically today! To the extent that any instruction exists physically. [09:29]
Diablo-D3 on modern cpus, in any of the x86 modes that have x87, its all emulated by microcode [09:29]
freeone3000 This is true of literally every instruction on x86 though. [09:29]
freeone3000 what, you think avx512 is done in circuitry? [09:29]
Diablo-D3 rolls eyes [09:30]
freeone3000 Fairly sure the emulation is still faster than an actual 8087, too. [09:30]
Diablo-D3 x87 isnt just a set of instructions, its a stack processor instead of a register one [09:31]
Diablo-D3 it also was never 754 compliant, and had a really odd internal representation of 80 bits (thus necessitating very weird stuff like long doubles not being 128 bits) [09:31]
dmlloyd looks like risc-v has a decimal FP extension [09:32]
freeone3000 right. and everyone, including intel, would like to pretend that this is not the case. [09:32]
freeone3000 dmlloyd: ...right, but, risc-v. [09:32]
Diablo-D3 x87 cannot be called from x64 long mode. [09:32]
freeone3000 everything's an optional extension. [09:32]
dmlloyd indeed ? [09:32]
gbobby I assume one could call some floating point instructions from amd64 long mode? [09:33]
gbobby what's all that stuff called... SSE2/3/4, SSSE3, something..? [09:33]
Diablo-D3 gbobby: only as normalized sse family stuff [09:34]
Diablo-D3 thats actually 754 compliant, and works like normal x86 ops [09:34]
freeone3000 gbobby: You can call floating point instructions, yes. You can't do the weird-ass stack stuff, you can't put it in binary mode, you can't rotate arguments, and you can't even call one-argument multiply. [09:34]
gbobby good to know... just in case I'll ever need it in some assembly language experiment [09:34]
Diablo-D3 they basically cloned powerpc altivec and brought it to x86 to finally kill x87 [09:34]
Diablo-D3 gcc and clang on x64 only emit sse ops for fpmath [09:35]
gbobby yeah, altivec is what you have on the ppc64 [09:35]
gbobby the ppc64 assembly language doesn't look very nice either, by the way, at least not the way it's represented with gcc [09:35]
Diablo-D3 gcc does whatever is fastest, it doesnt care waht it looks like [09:36]
cheeser this should probably go somewhere else at this point. [09:37]
gbobby anyhow, with regards to ActionScript -> Java use of double... [09:38]
gbobby I guess the question whether the results are going to be "the same" is more or less actually a question of what the required precision of those results needs to be [09:38]
Diablo-D3 [09:24:02] <Diablo-D3> you could do Double d = 16.188 + 1.16436; System.out.printf("%f %a\n", d, d); [09:39]
Diablo-D3 compare it to the same usage of printf on c/c++ [09:40]

adadelta I have a spring boot application that's has an application.yml file. I'm building it and including in another Spring boot app. It's complaining that it can't find the config during startup. Is there no way for me to do this unless adding that config to the wrapping spring boot application? [09:41]
radicate Quick question - perhaps someone here could help me figure out a solution to this issue.. :x - In short, InetAddress.getByName only seems to work when being run with root [09:41]
Addax where is it in the "wrapping spring app's" classpath? [09:41]
Addax radicate: that sounds odd - I'm not root on my system, but I just issued InetAddress.getByName() without any escalation [09:43]
Addax looks like isReachable requires it though [09:45]
radicate Addax: I'm trying to run it on two different linux machines, both claim that the host I'm checking is unreachable, but when run with sudo it is reachable [09:46]
Addax right, it's isReachable(), not getByName() [09:46]
radicate Oh, I firstly run getByName [09:46]
radicate Then on the InetAddress that's returned I'm running isReachable [09:46]
radicate Am I using it wrong? :x [09:47]
Addax [09:47]
Addax no, isReachable() on linux requires root [09:47]
adadelta Addax: Just the normal stuff in a maven project, "src/main/java [09:47]
adadelta and test [09:47]
Addax adadelta: again, where is that resource being located in the classpath [09:48]
radicate Addax: Do you know if there's a certain thing I could configure on a Linux machine to allow this to work on a non-root user? [09:49]
Addax radicate: suid, I guess? ... or use something else, which is why I posted that crunchify thing [09:50]

radicate I can't modify the implementation of the isReachable, I must use the original one :x [09:51]
adadelta Addax: The resource is in src/main/resources but in a different project, so packages are different. I know that the wrapper project wont read straight of the bat because of that. [09:52]
freeone3000 radicate: should be distributed with the JDK. Are you running something other than java? [09:52]
radicate freeone3000: OpenJDK [09:52]
radicate It gives me this error when I suid the java binary [09:53]
Addax no, they're not different [09:53]
freeone3000 yikes, do not suid the java binary. [09:53]
freeone3000 also don't suid your python interpreter or your bash shell or your c interpreter I shouldn't have to say these things. [09:53]
radicate Haha. I'm trying to find a way to run the InetAddr.isReachable method from a non-root user - do you perhaps have any suggestions? [09:54]
radicate I also tried playing around with setcap [09:54]
Addax adadelta: so look IN YOUR CLASSPATH for that file [09:55]
Addax radicate: why do you have to use InetAddress' isReachable() [09:55]
radicate I've been here a couple of days ago and complained about Apache Ant [09:56]
radicate It's using it under the hood [09:56]
Addax yes [09:56]
Addax well, find that module and replace it with something good [09:56]
radicate Ha. perhaps that's a good option [09:56]
radicate You think I could create an alternative module based on the solution you sent here a couple of minutes ago? [09:57]
Addax sure, figure out what class is using InetAddress.isReachable, put another version of that class in the classpath ahead of whatever the original class is, profit [09:58]
radicate Interesting! I'll take a look at it [09:58]

eric- why would that be? [12:57]
Addax alexi5_wrk: I usually create the object model in java, see what hibernate generates, tweak [12:57]
Addax eric-: why would which be [12:57]
alexi5_wrk Addax: ok. so you have hibernate generate the sql script and then you modify it ? [12:58]
Addax eric-: the simplest answer is because nobody needs or wants it to be in the standard library. Map<Integer, Object> is fine if you need a sparse array. [12:58]
alexi5_wrk <Addax>: also do you use tools like liquibase and flyway ? [12:58]
Addax alexi5_wrk: Not usually, I have hibernate show me DDL and then I tweak the object model until it's more efficient [12:58]
Addax I have used them, yes, but I typically don't [12:59]

yawkat freeone3000: well, 500 isnt a valid offset? [02:38]
Addax why? [02:38]
coder7of9 yawkat i do not understand this is as it was earlier with less lines of code. [02:38]
yawkat coder7of9: i did not look at the earlier code [02:38]
freeone3000 yawkat: Z says it is. It parses fine with "yyyy-MM-dd'T'HH:mm:ssZ" [02:39]
OnceMe actually this is a different question [02:39]
Addax OnceMe: it really isn't [02:39]
cheeser it's still about parsing html. so it's the same answer. [02:39]
coder7of9 okay but you do not think i have a good result i am after millis for a date and considering timezone [02:39]
Addax you want the content of something in an HTML page, jsoup is the answer [02:39]

ernimril Blankspace, know your OS, /usr/lib/jvm/* [04:52]

wad I'm back! Reboot successful! [06:51]
surial (but, they do. goddamn I hate these fucking keyboards, what a disaster). [06:51]
surial It's supposed to take about 8 seconds, not 5 minutes. [06:51]
wad This is a mac. It takes FOREVER to reboot. [06:52]
surial no it doesn't. [06:52]
surial if you have a bazillion apps open it'll also open those after a reboot. [06:52]
wad Mine does. It's brand new. $3000 machine. After I click my login profile icon, and enter my creds, I get a slowwww progress bar. [06:52]
wad I think it's decrypting the hard drive or something like that. [06:53]
Diablo-D3 surial: its osx [06:53]
surial Perhaps you had an update. or you bought a 15 year old mac? Should take 8 seconds from typing in your password (which is the UEFI booter, not the OS. Full disk crypto done right) until base OS is up, then all apps that were open before are launched. maybe do a restart and explicitly tell it NOT to restart any apps (or just close evverhthing but finder, then reboot). If it's taking that long, bring it back, broken. [06:53]
surial wad: It's not. Seriously, hardware broken if it's taking longer. [06:53]
Diablo-D3 boot time AND shutdown take dramatically longer. [06:53]
surial dafuq are you all on about? I'm typing this ON A MAC. [06:53]
Diablo-D3 no clue why, got tired of trying to figure out why [06:53]
surial 8 seconds. Dafuq are you guys doing with your hardware? Pissing on it? [06:54]
Diablo-D3 Im typing this on a mac too. [06:54]
Diablo-D3 mbpr 13" late 2012 [06:54]
Diablo-D3 its never been faster ever since I put win10 on it [06:54]
surial congrats for not having the shite keyboard. [06:54]
surial okay, maybe the dual boot thing is the problem? [06:54]
wad Huh. Last time I used a Mac was 1992. I much prefer Linux, but my employers insist that it's insecure. My choices are Windows or Mac. >_< [06:54]
surial anyway, back to my point. [06:54]
Diablo-D3 not dual booted, took osx entirely [06:54]
surial wad: linux and windows have the control key. the equivalent in mac is the command key. [06:55]
wad I'll take this down to the IT department, and have them take a look. Seems crazy that it takes so long to boot. [06:55]
surial wad: which is weird, because macs do HAVE a control key, but that is a key that is totally new and has absolutely no equivalent on linux or windows. [06:55]
Addax mac is a great dev platform, but that long to boot sounds like it was doing an OSX update [06:55]
surial So let's call this key the flooble key. [06:55]
surial it's the one that says 'ctrl' on it, but if I keep calling it control you're gonna get confused. [06:56]
surial wad: the flooble key serves 2 purposes. [06:56]
wad Okay, while I was out... did I miss good info? "Mac OS X 10.5+" or "Mac OS X" for the IntelliJ keyboard setting? [06:56]
Addax wad: use the default. You'll be fine. [06:56]
surial wad: first of all, _IN TERMINAL_, the flooble key is sent to the host OS when using terminal ops, and CMD is free for the control of the terminal app itself. So, in terminal, CMD+C is still copy. Flooble+C is sent to the host OS and will presumably send a HUP signal if you're sshing into a linux box. [06:56]
surial wad: second of all, everywhere else, the flooble key is specifically used for keyboard navigation in text editors. [06:57]
wad surial: just like a CONTROL-C then. [06:57]
surial (it also serves as yet another meta-modifier on modifier keys. you have CTRL+CMD+Q which is 'lock screen' for example). [06:57]
surial wad: On macs, flooble+A will go to start of line, ANYWHERE. [06:57]
surial well, maybe except in microsoft shit because, well, they make shit. [06:57]
wad Like COMMAND-LEFTARROW. [06:57]
surial in eclipse, intellij, etc, Flooble+A goes to start of line. [06:57]
wad flooble-e goes to the end, just like in vi! [06:58]
wad Nice! [06:58]
surial It also does in an 'alert' popup in the browser in javascript (the one that asks for input), the URL bar of chrome, the actual terminal (becuase in terminal/posix command line, CTRL+A is go to start of line, as in vi and stuff). [06:58]
surial so, _EVERYWHERE_, Floobe+A is start of line, Flooble+E is end of line. [06:58]
surial On windows and linxu this just cannot be, you don't have the metakeys to waste one on key nav. [06:58]
wad That's actually pretty nice... [06:58]
wad HOME and END keys do nothing. [06:58]
surial oh, they do. [06:59]
surial home goes to the top of doc, end goes to bottom of doc. Which is disconcerting as fuck, as on windows, they go to start/end of line instead. [06:59]
surial if you're on the laptop keyboard, uhm.. Fn+up is home I think. [06:59]
surial no, Fn+Left. eh, I rarely need to go top of doc. [06:59]
surial but, yeah Fn+left = Home, Fn+Right = End, and they go the very toppity top and the very bottomy bottom. [06:59]
wad Nobody does. So let's map a KEY ON THE KEYBOARD to that function! [07:00]
wad >_< [07:00]
surial anyway, the point being, basically either [A] kiss your flooble key goodbye as useless wart, or [B] adopt a different key layout entirely on macs versus non-macs. [07:00]
wad I spent 2 days trying to convince Karibiner Elements to make keys act like I'm used to. I just gave up an hour ago. Now I'm retraining 3+ decades of muscle memory... [07:00]
surial Personally I'm for my GUIs all macs everywhere so I very much use the Flooble key everywhere. But it's kind of a choice to make here. [07:00]
waz most of the mac shortcuts are emacs based [07:01]
surial If you get used to it, you start pressing CTRL+A on windows to go to start of line and selecting all fucking text, inherently zipping to the very end of your goddamn document when all you wnated to do is go to start of line. [07:01]
surial so, you know. Think this choice through. [07:01]
omonk [omonk!~omonk@unaffiliated/omonk] has joined ##java [07:01]
wad So, as for IntelliJ, there are 3 defaults, and none of them seem right: They are for gnome, KDE, and XWin. [07:02]
surial anyway, once you decided.. check what intellij does. I know eclipse, out of the box, is macy. As in, eclipse on macs default to emacsy keyboard bindings, at least for anything that's just flooble-key based. [07:02]
surial I'm of the opinion that adopting the default keyboard layout of an editor is stupid, and that's one place where the tool should adopt to you and not the other way around. So, if intellij has nothing, make one, or google for one. [07:02]
surial (And anybody who thinks you should 'just' learn the default keyboard bindings of intellij, file a fucking bug with jetbrains that they should remove their keyboard binding config screen as a negative feature, and if you don't wanna, I call bullshit). [07:03]
wad There are these two Mac ones, I just don't know which is the latest-and-greatest. One has no version, the other ones is "10.5+", which implies it's for that version and everything after? [07:03]
waz wad can you fucking read? [07:03]
waz it makes a suggestion for you [07:03]
Addax I find the default IDEA keymapping fine [07:03]
waz mock Addax [07:03]

waz you idiot [07:03]
Addax whether someone else chooses to use it or not is up to them [07:04]
Addax waz: yeah, well, I've been watching the "here's your new OS" lecture in ##java, so... [07:04]
waz my last truly new OS was in 1999 [07:04]
waz though I guess 0S9 to OSX was kind of a new one [07:05]
waz key mappings still worked though :) [07:05]
Addax wait... you mean MacOS9 [07:05]
waz yeap [07:05]
Addax I was thinking you meant the POSIX one :) [07:05]

waz tah tah [07:06]
wad I just quadruple-checked, I'm pretty sure I'm not missing anything on the UI. There is an option in the dropdown labeled "default copy", but that's in a different, smaller font, so I'm assuming it's something else. I could be wrong. Other than that, there are three options marked "default", but I'm noting using KDE, Gnome, or WinX. [07:07]
waz it offers you the older one or the newer one [07:07]
waz and says that the older one is there for those used to it [07:08]
waz gee [07:08]
wad I'm going to have to relearn how to interact with this IDE, and undo 13 years of muscle memory. [07:08]
waz wonder which one I should use? [07:08]
palasso [palasso!~palasso@unaffiliated/palasso] has joined ##java [07:08]
waz you can map to whatever you like [07:08]
wad Okay then! I'll use the 10.5+ one. [07:08]
waz it's completely configurable [07:08]
waz you don't have to relearn anything [07:08]
wad Oh yes I do. Do you know how many times, in this conversation, I've typed the wrong key to move my cursor? I type "HOME" to put it at the beginning of my line of typing. Doesn't work. I've got a lot of relearning to do. :( [07:09]
wad But CTRL-A works now! [07:09]
