@HMH your threadsafe queue doesn't look threadsafe to me btw

13:56

and I don't know why it needs to be parametric over its container and the smart pointer it uses

13:56

can't it just store the element type directly

that might be true, I guess you can enlighten me then ?

13:57

If it stores the element type directly I have found that this creates issues with ownership, thus the smartpointers

in that case, can't you store smartpointers in the queue instead?

14:01

like instead of queue<T>, you just use queue<unique_ptr<T>> if you want it behind a unique_ptr?

I see

re thread-unsafety:

14:02

e.g. look at the Front implementation

14:02

it takes the lock, returns the reference and then releases the lock

14:03

but the reference can become invalid as soon as the lock is released

14:03

the calling function can't do anything with the returned reference AFAICT

Yes, that is why there is GetLock

14:04

and that is also why I use a recursive mutex

14:05

So ideally you do something like this:

{
auto Lck = Q.GetLock();
Q.whatever()
...
}
// Lock released

14:07

The lock in there is to make reading always threadsafe but yes after returning things might have changed.

but what use is the lock in the Front function?

14:07

if you can't use the reference anyway?

It is probably not too useful to have these extra locks in there. Do you have an Idea to enforce locking, so it becomes impossible / hard to forget calling GetLock btw ?

Sometimes eyes are blocked and you can't change

abc

@HMH you could force the usage of Queue through a wrapper which aquires the lock in constructor and releases it on destructor

Nonono

nonono?

<dezzer> yesss

have you ever tried Vivaldi browser?

<dezzer> vivaldi is shit

22:52

<dezzer> opera is better

vivaldi is closed-source

why is shit

22:53

feels much better than google chroem

22:53

even if the same engine

apparently opera is closed-source as well

22:53

wow, like it's 2000 again

I don't know, what they did to google chrome

22:53

but it works like shit (edited)

have you tried firefox? ^^

yea

22:54

i tried opera, firefox, chrome

22:54

they are most popular

have you tried the new Firefox tho

that's why im asking what do you think about vivaldi

@Beefywhale

what they changed?

Everything

suddenly, they are monster

part of the rendering engine was rewritten in rust

of perfromance

22:54

or what

performance and the look

22:55

it uses barley any ram

22:55

even with 100+ tabs open

<dezzer> firefox is the best browser

I have to say, that firefox looks great

23:05

I will test it

23:05

but first look, make me feel good

23:05

Firefox has different engine chrome yea? it's not chromium xD?

<nemo2> firefox forever!

23:06

<nemo2> has been a mozilla fanboy since mozilla was a thing

23:07

Great, now i have to install firefox on android

23:07

and all will be great

23:07

I love Sync thing

23:07

that's why i used google

23:07

chrome

<nemo2> eh. firefox sync has been around a looooong time

23:26

<nemo2> firefox worked awesomely on my ancient android 4 phone

okok, fanboy

23:26

<nemo2> was the only browser that did GPU acceleration so scrolling worked ok. was funny to see people freaking out over smooth scrolling when chrome finally added it

23:26

<nemo2> I was like. eh. have had this for years on my PoS phone

chrome since 41 could do it too

23:27

but.. you had to enable it

<nemo2> but... yeah, I was doing firefox sync against android like... 5 years ago.

23:28

<nemo2> and. had local encryption back then

23:28

<nemo2> Google only added it recently due to pressure and still isn't default

23:28

<nemo2> so everyone was happily uploading their wifi passwords to NSA

Like, it does matter in this times

23:29

We can't do much about this

<nemo2> eh. make 'em work for it at least

Btw. i used firefox, but then firefox worked like a dinosaur

23:29

were very slow

<nemo2> shrugs

23:30

<nemo2> no browsers were great back then. not even chrome

so i switched to chrome, which were fast then

<nemo2> and... depends on what you used it on

23:30

<nemo2> Chrome was fast on google properties, no shock

but now I started lookin for new

23:30

browser

<nemo2> but... consider nacl. google was pushing nacl due to limitations of their own JS engine

and you told me that firefox were rewritten

23:30

and tbh, it works like a boss

23:31

Can i somehow, limit Ram usage of firefox?

23:31

1 view(s)

23:32

or it's standard? :D!

<nemo2> there are ram settings sure

23:32

<nemo2> for one thing, latest firefox is now using content processes, like chrome did before it

Like wherE? Can't find

<nemo2> you can reduce # of content processes

23:32

<nemo2> the fewer you use, the less ram

23:33

<nemo2> one interesting thing in nightly BTW is hovering over a tab shows process ID

23:33

<nemo2> so you can see when tabs are unloaded too

Im not really familiar how browsers works

<dezzer> wood pcs

23:33

<dezzer> confirmed

23:33

<nemo2> about:config

I mean, inside

<nemo2> I wouldn't recommend screwing w/ 'em too much

i like to know how CSS is rendered and structure

23:34

thats all

<nemo2> is intended to be dynamic based on system capacity

23:34

<nemo2> dom.ipc.processCount;4 ← default number of content processes. cranking it down to 1 or 2 will save ram

It will make browser less effective?

23:35

I bet yes?

<nemo2> eh

23:35

<nemo2> not thaaat much

don't screw around in about:config:D

<nemo2> stuff gets unloaded pretty aggressively anyway

23:35

<nemo2> and you'll still have content process so rest of browser should be responsive

at least if you want to blame the browser later

<nemo2> but up to you

I mean, it's more like for testing purposes

23:35

i have enough ram

23:35

Xd

<nemo2> you can always try it in a test profile

23:35

<nemo2> firefox -no-remote -P test

Okay i understand now, it create 7 process by default (edited)

23:36

for web, extensions, files and... one for general i guess

23:37

I will try with 3, I don't run much tabs at once

23:37

a lot*

<nemo2> there's a bunch of things that make processes. browser interface, rendering process, web workers, content processes...

23:37

<nemo2> that config entry is for the content processes tho

23:38

<nemo2> btw, about:memory if you're curious what sites are being greedy

23:38

<nemo2> about:about for all about pages

oh shit

<nemo2> oh. also. did you ddnet guys notice we did a hedgewars release?

are you from hedgewars devs?

<nemo2> yesssss

I tested that game, while using OBS haha

23:39

beceause we had a problem with Radeon carts

23:39

i mean, more like we thought it was problem with game

23:40

but, then we figure out, that OBS has troubles with SDL hooks

23:40

and crashes

<nemo2> what is OBS?

Software for streaming video

<nemo2> ah

Free and open sourcce

<nemo2> interesting

23:40

<nemo2> we finally fixed our video encoding this release BTW

https://obsproject.com/

<nemo2> only thing I've ever used is gtk-recordmydesktop

its like, best free option.

<nemo2> and have never tried streaming

23:41

<nemo2> but good to know

I don't know any good alternatives

23:41

only paid one

23:41

I think, that almost every twitch/youtube streamer

23:41

use OBS

23:41

because of plugins and easy configuration

23:41

also good performance

23:41

anyway..

<nemo2> why would streaming software need SDL hooks/

23:43

<nemo2> ?

No idea, maybe to catch somehow scene

<heinrich5991> nemo2: no, didn't see you did a release

23:44

<heinrich5991> link? :)

I'm just user, but saw crash log

<nemo2> heinrich5991: https://hedgewars.org ?

it was crashing on sdl hook

<heinrich5991> Savander: if you want to be able to complain about the browser, don't change stuff you don't exactly know in about:config

23:45

<nemo2> heinrich5991: well. doing it in a test profile should be fairly harmless

heinrich, i revert changes

<heinrich5991> good :)

don't worry, I was just curious

<heinrich5991> nemo2: "There's no Mac OS version this time, but we hope to release one soon."

you know, children's curiosity

<nemo2> heinrich5991: can't find anyone to do the build

23:45

<heinrich5991> I suppose that's due to no macos machines being available?

does hedgewars is opensource?

<nemo2> heinrich5991: well. unc0rr's coworker has one. and was trying to do build. but ran into some SDL lib loading error

23:46

<heinrich5991> have you thought about cross-compilation? I recently made it possible to cross-compile ddnet to macos

23:46

<nemo2> heinrich5991: heh. even more work that

23:46

<heinrich5991> not in the long run :)

23:46

<nemo2> hum. p'raps

23:46

<heinrich5991> or you could build on CI and use that artifact, that's a good idea anyway

23:46

<heinrich5991> (CI, I mean)

23:46

<nemo2> I remember setting up iOS toolchain under linux and that was super painful

23:47

<nemo2> and, Savander, yes, of course it is

23:47

<heinrich5991> nemo2: you need to change where the executable looks for its libraries

23:48

<nemo2> Savander: https://hg.hedgewars.org or use our download page for the release tarball

23:48

<nemo2> Savander: there's also https://hedgewars.org/kb/BuildingHedgewars but most of the non-linux build instructions are pretty sucky right now

23:48

<nemo2> heinrich5991: if you want to help... would be appreciated

23:48

<nemo2> esp by the OSX users

23:51

<heinrich5991> nemo2: hedgewars uses hg? I wasn't able to wrap my head around that one :(

Qt isn't paid library?

<heinrich5991> no, it has an LGPL license IIRC

On their website, i see big button

23:51

Buy QT

<nemo2> on what website?

qt.io

23:51

https://www1.qt.io/buy-product/

<nemo2> Savander: BTW, if you're into privacy and maybe speed and don't mind totally ignoring heinrich5991's warning, I have some about:config settings I like to turn on - some are visible in Prefs too sooo

23:52

<heinrich5991> the URL sounds fishy :o

23:52

<heinrich5991> although it probably isn't

I mean, i found it in google

23:52

first link

23:53

Qt | Cross-platform software development for embedded & desktop

23:53

And obviously, i can start Free trial (yea)

<nemo2> Savander: privacy.trackingprotection.enabled;true turns on tracking protection always, not just in private browsing - may possibly break sites although I've never encoutnered this. You get a warning in URL if it is blocking things

23:53

<nemo2> Savander: speeds things up too obv

yea, i saw that options

<heinrich5991> just install ublock instead

i enabled it !

<heinrich5991> or access the option via the actual options, not about:config

23:54

<heinrich5991> "ublock origin", that is

23:54

<nemo2> heinrich5991: it used to not be exposed in settings so I have no idea where to find it there

now there is privacy and security

23:54

tab in settings

<nemo2> heinrich5991: btw, ublock/umatrix have a super annoying bug that's been driving me bonkers while I wait for the noscript port to be completed

23:54

<nemo2> heinrich5991: <noscript> tags are not flagged to be parsed, by them. bz seems to feel this is fail on their part

23:54

<nemo2> breaks a ton of sites

23:55

<nemo2> (breaks their fallbacks I mean)

23:55

<heinrich5991> ublock isn't about blockign JS

23:55

<nemo2> NoScript thankfully still works, in legacy mode. I'm following the bug on the full port. He made a webscript version too, no idea if it is more sensibly setup

23:55

<heinrich5991> it's more about blocking trackers etc.

23:56

<heinrich5991> you can use it in the script-blocking mode as well

23:56

<nemo2> heinrich5991: eh. toma-toe tomahto

23:56

<nemo2> heinrich5991: I was more interested in script thing.

23:56

<heinrich5991> but since that's not their main business, there are bugs, apparently

23:56

<nemo2> https://bugzilla.mozilla.org/show_bug.cgi?id=1214733 the noscript bug I'm avidly following

1214733 - (webext-port-noscript) [tracking] Support NoScript as a WebExtension

23:56

<heinrich5991> I currently don't like having to unbreak every website I'm visiting

23:56

<heinrich5991> ublock doesn't break the websites ^^

23:57

<nemo2> heinrich5991: vast majority of sites I use work well enough w/ script blocking

23:57

<heinrich5991> well, not for me

23:57

<nemo2> heinrich5991: in fact on mobile I leave Js off most of time

23:57

<nemo2> good for security, privacy, bandwidth and battery

Firefox has cool feature, a CLI

23:57

pref set privacy.trackingprotection.enabled true

23:57

cool command

<heinrich5991> I usually browse a lot of different sites

23:57

<nemo2> eh. me too

23:57

<heinrich5991> security meh

23:57

<heinrich5991> since you're gonna enable it anyway if something breaks

23:57

<nemo2> surprising how many of them have usable fallbacks

23:57

<heinrich5991> privacy okayish

23:58

<nemo2> heinrich5991: well... sometimes I just fix their stupidity in stylish

23:58

<heinrich5991> bandwidth and battery ok

23:58

<nemo2> for example SMBC comics after-comic is JS toggled, so I made a stylish rule to always show it

23:58

<nemo2> minor things like that

23:58

<nemo2> I'd say I pretty much never toggle it on

23:59

<nemo2> heinrich5991: security.mixed_content.block_display_content;true blocks more sites for me actually

23:59

<nemo2> aforementioned SMBC for example

23:59

<nemo2> if you use https everywhere they forcibly serve the comic as hardcoded http
