just for safety measure, put a try catch in that catch

you never know

@iKlsR Good point, but you have to try catch that too then, so you'll end up in an endless loop of try-catch-finally-try xD

so the first 4 episodes of new season of Game of Thrones are ok I guess

Asada Shino

@ton.yeung Hence the ignore(e);

We don't want anything to do with it, it never happened

nhahtdh

function random() { throw Math.random(); }; try { random() } catch (r) { console.log(r) }

Asada Shino

Eventually it'll go away

Right?

Catchball oriented programming

Asada Shino

If you don't care about the performance of your code, just try catch your main function

@Hakase u filthy pirate u

Which manga?

Hakase

I don't read manga

iKlsR

@Hakase lol u can't read

@ton.yeung I think there are apps getting their source from illegal sites

Asada Shino

Class Baseball extends Throwable {
public static void Baseball() throws Throwable {

2:06 PM

guys wat is this

is it java?

iKlsR

@AsadaShino just make that a Factory so we can coin unique bugs

Asada Shino

From what I remember of the language, it is

Bahaha

iKlsR

@Hakase COBOL

Asada Shino

BugFactory.CreateBug(Bug.Reasons[Math.Random(0, Bug.Reasons.Length]))

nhahtdh

@Hakase I'm not sure whether Throwable can be part of throws clause, though

@ton.yeung Those aggregator sites mirror the content soon (TM)

Hakase

A: Is "throws Throwable" good practice

You should not throw Throwable. Here's why... Throwable is the top of the hierarchy of things that can be thrown, and is made up of Exceptions and Errors. Since Errors by definition arise from unsalvagable conditions, it is pointless to include them in your method declaration. That leaves just E...

code review?

ye they're nice guys :p

Asada Shino

@ton.yeung I thought it did use extends, lemme check

Hakase

no extends

Asada Shino

Ah right

nhahtdh

@ton.yeung Go ahead. Though I don't like the fact that every license series in the US simply pull the plug for the rest of the world

Asada Shino

2:09 PM

and Java has extends and implements iirc

It's been years since I last used Java

Hakase

@iKlsR it's clearly upside down − nobody puts walls of text on the front page

nhahtdh

@ton.yeung Manga and anime is less of the case

But it is the case for LN

And there are series which simply stopped getting updated/scanlated when it is released in the US

@ton.yeung Chapter 3?

Yeah, the only way is to read raw

Unless the series is popular enough, no one is going to scan the US book

And even if they scan, the publishers are very efficient at taking them down nowadays

Q: How do I calculate clock speed in multi-core processors?

Is it correct to say, for example, that a processor with four cores each running at 3GHz is in fact a processor running at 12GHz? I once got into a "Mac vs. PC" argument (which by the way is NOT the focus of this topic... that was back in middle school) with an acquaintance who insisted that Mac...

I'm reading the basics of CPU speed and I still don't know whether more cores is better on average for a modern day's pc (and my tasks specifically)

it looks like it's not worth getting i7 cpus with 4 cores for a home pc

an i3 cpu with just 2 cores seems more suitable

I may be completely mistaken tho

Asada Shino

I use an i5 at home, for that reason

nhahtdh

@Hakase i7 has hyperthreading, but it is going to be only slightly faster (20%, last time I read) than non-hyperthreading

Asada Shino

Most games and such don't support multithreading, or at least not very well, so there's not much point

Hakase

I assume most apps even today are single-threaded

so I suppose the more cores and the more threads a CPU can pull, the less time it spends on processing each app

Asada Shino

Probably, except bigger projects/programs. Where it's necessary, I guess

Hakase

2:31 PM

so 8 threads of 4GHz CPU is actually 500MHz per process?

nhahtdh

I prefer having 4 core, since in worst case, one core is going to be used by Windows Update, which leaves 1 core for background stuffs and another core for browsing/watching video

Asada Shino

@Hakase Wut? xD you mean 8 threads of 500 MHz is 4GHz?

Ah right haha :P

nhahtdh

@Hakase No. each thread is 4Ghz

Hakase

oh?

nhahtdh

Though for hyperthreading, I don't think you can have both threads running at the same time on one core

Unihedro

2:32 PM

Having multiple cores improve clock rate with or without threading in an application.

Asada Shino

If you have a perfectly implemented multithreaded application, you'd have about equal performance compared to a single UBERcore, but that's rare :P if it even exists

Unihedro

^^

Hakase

so 4-core 4-thread CPU is 50% as fast as a 4-core 8-thread CPU at the same number of GHz that is listed in hw specs?

nhahtdh

Anyway, high clock rate doesn't mean anything with all the cache miss and disk access

Hakase

@AsadaShino we're talking about today's world and today's apps

Asada Shino

2:33 PM

You're only as fast as your smallest bottleneck :P

Unihedro

@nhahtdh Yeah, so it's moot.

Hakase

@AsadaShino which is why I wanna find out which it is

Asada Shino

@Hakase Then you'd be better off with a 32 GHz core, rather than 8x4GHz, I guess haha

nhahtdh

@Hakase No, as I said above, hyperthreading only improve the speed a bit, since it execute the other thread when the first thread go to fetch data from cache

Unihedro

The entire star board are pictures :D

Hakase

2:33 PM

and whether having more threads and cores is slowing down single-threaded apps

Asada Shino

But then again, do 32GHz cores exist? xD

nhahtdh

It shares the execution part, only the fetch part is duplicated, iirc

Hakase

@ton.yeung idk if there's a reason to use i5 instead of i3

nhahtdh

I think there are new instructions in newer processors, but whether programs are compiled to use them is another matter

Hakase

3.8 vs 3.9 doesn't really matter for a home pc

but what about that number of cores difference?

if there are 4 threads in both, does it mean anything?

nhahtdh

2:37 PM

Real core is better than virtual core

Hakase

how

Asada Shino

From what I know, physical cores are better than virtual cores, since they don't run on one core

Virtual cores still run on a single core, but it simulates two cores

Hakase

@AsadaShino why?

someone just said above that the GHz is per thread, no?

then cores shouldn't matter

nhahtdh

Like I said above. Virtual core shares execution pipeline, so 2 threads can never be run at the same time on the same core with hyperthread. If you are running intensive program on multiple cores, physical core should be better

Asada Shino

@ton.yeung This is the reason I'm thinking of getting an i7 xD But I'll wait for the next generation which is coming out in Q3 this year I believe?

I have my browser open and a youtube video and some downloads, while playing a game or something xD And I cba to close them every time I do something else

Hakase

I'd say "if you only download music, just get the oldest, cheapest CPU you can find that fits your socket"

Asada Shino

I'd rather just overpower these things than have to pay attention to little things

Hakase

I think so

Asada Shino

Then I'll wait for Skylake and then get the... Rockwell is the latest, right? Rockwell i7 probably

nhahtdh

2:44 PM

@Hakase If you are using Windoze, you need to take into account Windows Update

Hakase

utorrent only ever uses one core according to procexp

Asada Shino

Doesn't that depend on the application?

Though from experience, most torrenting programs seem to only use one core

Haswell, right, that one then xD

Though it'll still be expensive

The mobo+cpu combo I have seen before, was about €850 a few months ago

@ton.yeung Don't cpus get cheaper when a new generation is released?

nhahtdh

Programs are usually compiled with the lowest denomination, so most of them don't take advantage of the new instruction. Maybe except for new games

Asada Shino

Oh, dang, I've never really looked at price flow...

Hakase

yes but not really enough

15% maybe in the first half a year, not a lot even much later

Asada Shino

2:47 PM

i7 are quite expensive~ But I want one, so I don't have to care about closing programs to not have stutter in a game because my cpu is capped by other programs

@ton.yeung e edition? the K versions? Or something above that?

Aha

That sounds a bit overkill for what I want to use it for xD

Hakase

@AsadaShino what actual use cases are we talkin about

Asada Shino

@Hakase Game + browser with 20+ tabs + torrents + youtube video + teamspeak

Hakase

you should never run torrents on your gaming pc

get a nettop to handle the torrents

Asada Shino

@ton.yeung Aha, nah, I'll stay away from extreme versions

Frosteeze

@AsadaShino i had no problems with that with my i5

maybe reason why you stutter is your torrents

Hakase

2:49 PM

it most certainly is

Asada Shino

@Hakase I've still not gotten to doing torrenting on my NAS~ I forget ~_~

Hakase

get to it and stop worrying about unnecessary purchases

just use what you already have, smartly

Asada Shino

@Frosteeze Probably, nearly 2k torrents in the program (not all active, probably) could do that

I'll find out what program I can use for my Synology then :P

@AsadaShino That's going to take a long time to load for uTorrent

Hakase

idk why people who play games and do weird computer stuff only have one computer for all of that

nhahtdh

@Hakase We are cheapskates.

Hakase

actually not

Asada Shino

2:52 PM

@nhahtdh I use qBittorrent, it still takes a bit to load, sometimes it just freezes, I'm going to clean it up when my current batch is finished downloading xD

Hakase

get top of the line i7 and do everything on it?

Toshinou Kyouko

@ʞɹɐzǝɹ was it you who was asking what I thought about Miyazaki's biography? I enjoyed the talks at the start of the book, but I thought the interviews and stuff weren't that interesting

Hakase

doesn't make sense

more expensive than multiple computers with weaker processors, suited for different tasks

nhahtdh

@Hakase You need to get like 16GB RAM, plus SSD for speed

Asada Shino

I do have a i7 2770K lying around, would it be worth it to use that instead of my current i5 3570K? xD

nhahtdh

2:53 PM

Well, torrent can go to NAS

Hakase

torrent clients require only very little ram

Toshinou Kyouko

i9

nhahtdh

Browsers can take time quite a lot of RAM

Toshinou Kyouko

iAye

Hakase

i11

goes up to 11

Asada Shino

2:54 PM

I already have 2 SSDs and 16 GB RAM, but I'm unable to get it to run on 1600MHz without getting strange stutters/freezes, I'll need to fiddle with timings and I don't trust myself to not screw that up xD

Taisho

Frosteeze

what about your vid card?

Toshinou Kyouko

I agree with @Taisho

Asada Shino

Even though it has an XMP profile for 1600MHz

Hakase

games, videos, browser − main computer, everything else − separate machine under the table, no video card or ssd required

Asada Shino

2:55 PM

@Frosteeze 970GTX

nhahtdh

I only have like 4GB RAM at work, and since my work requires me to research stuffs on the web mostly, I keep getting slow down due to swap

Hakase

@nhahtdh keep less tabs open

Frosteeze

that cant be it then lol

Asada Shino

Yeah xD

But I'm going home now :P

Hakase

@ton.yeung no it's not

Asada Shino

2:56 PM

I'm going to find out how to torrent on my NAS, so I can get that out of the way at least :P

Then I'll see what else I can do without running in the background :P

Toshinou Kyouko

:)

Hakase

@ton.yeung ok I'd like to know what you have to manage on them

@AsadaShino try reinstalling windows if you haven't already − guaranteed performance boost from no crapware you're most certainly had installed

@ton.yeung transferring what? from where to where?

nhahtdh

@Hakase I occasionally clean up tabs, but I don't normally realize that I have opened 10 tabs and I need to close them

Hakase

@nhahtdh firefox?

nhahtdh

Yeah

Hakase

2:59 PM

try 64bit dev edition

seems faster to me

@ton.yeung but why?

ugh this is why you have problems man

just don't move stuff

it's ok where it is

probably

idk maybe your job is a stuff mover lol

nhahtdh

I find it is a pain to manage all my external storage

Currently thinking of throwing all of them up to cloud

But it's > 5TB

Hakase

guys you don't need external storage if you got space in your desktop towers

internal is fine

just use local network to access files on other machines

nhahtdh

I don't have a stable desktop

Need to invest in a new one

Hakase

oh shit time to go home

@nhahtdh "int" infers that we're not in JS :D

nhahtdh

@Unihedro I know

Unihedro

if (b == 0) -> if (!b)

@Unihedro Clearly if b < 0 you should be using subtract(a, -b)

Unihedro

ohhhh

me no recursion master

Eric

:D

Recurse all the things!

Unihedro

:D

nhahtdh

Try-Catch-Throw instead of Return!

Frosteeze

use goto instead of recursion

Eric

3:37 PM

Oh god

Unihedro

Why not all?

Try-Catch-Throw + Return + Goto while using recursion - the more the merrier

nhahtdh

Is there any language that support all of them?

Unihedro

F#?

nhahtdh

Lol, I'm surprise that there is a language at all

Hakase

if anyone here thinks their computer could work faster, you're probably right and we can probably help you with that, so don't be shy to ask for advice

Unihedro

3:42 PM

Oh?

I've been uninstalling a lot of old software lately.

Hakase

swap "computer" with "life" and "faster" with "better" and it still works :p

lol :D

Hakase

@Unihedro you can probably get a better boost by reinstalling OS completely

Unihedro

... That's a brilliant idea.

Eric

int add(int a, int b) {

@ton.yeung looking forward

Eric

@Unihedro Good, cuz I almost killed myself before I finished xD

Unihedro

Oh noes :p

Hakase

3:44 PM

why

I still might need to buy hardware if this just dies all of a sudden

Unihedro

Fact: A HDD dies.

Hakase

I won't be looking for replacement parts since they're as expensive as the new ones

@Unihedro not soon enough

I still have my ancient seagate hdd from 2003 or whenever, it's running ok in the old tower

idk I've read about terrible seagate failures but they all work great for me

Unihedro

Should one reformat them?

Hakase

hdds?

depends

Taisho

Hakase

3:48 PM

if you know you absolutely will not have small files on your external drive, largest cluster size could get you a bit of extra space

small files eat up all the space on drives with huge clusters tho

and you shouldn't be storing them as separate files probably

unless you have no power over that

for example if it's an installation of some app

system drives should have the default 4k cluster size coz lots of small files and I think ssds have some optimizations towards that specific size, not sure tho

just not worth it most of the time

Unihedro

Ok!

@Eric Can you throw anything, not just Exception?
