hello guys... i have to mend a TRS cable, but i'm not sure on what to do with the isolation wires, any help?
gentle moss
tip ring sleeve?
and by isolation do you mean earth wires?
or is there a shielding around the L/R/E internal core?
@dense moon
dense moon
i'm not sure... there's some copper strings around another copper wires that are protected
gentle moss
are there 3 clear "core" wires?
dense moon
@gentle moss it's from a drum guitar hero set... so assumed that the outside wires are to diminish meddling and stuff
it's just one core wire, yellow
gentle moss
if they're fine strands rather than a single wire
they're either not supposed to be wired
or they're to be wired to earth
by the sounds of it, if there's one core wire, than the "strings" should probably be wired to earth
does it look like the ground on the left?
the "strings"?
dense moon
yeap, just like the left one but with only one signal
gentle moss
okay so you probably want to wire the core to positive (if it's TRS it should have two terminals in the jack) and then wire the strings to earth
gentle moss
yeah okay, so that looks like a standard jack connection, rather than TRS
TRS has two core wires and earth
dense moon
the wires on left were around the ones that were inside a yellow cape
i already removed it to see what it looked like
gentle moss
jack cables generally have the earth as a weave of cable around the internal core
dense moon
the conector is fine... the rest of the cable is ripped in three pieces by the bastard lying back there
gentle moss
haha
dense moon
oh, got it... sorry for the confusion
so... i just mend ground to ground and core to core?
gentle moss
yup
dense moon
and isolate them?
gentle moss
yup yup
dense moon
awesome!!!
won't be a problem if i mend all the three pieces?
i really need the length
gentle moss
it should be fine providing the connections are solid
in general when repairing fucked up cables as long as you pair like to like you should be okay
gentle moss
the key part is making sure they're well connected
twist each half together tightly etc
dense moon
yeah... i don't got any tin nor a weld stick
but i think it'll work
thanks a lot bro
gentle moss
this is the perfect example of a join, but if you do something similar it'll last a decent while
dense moon
that's the one i'll do

What does exactly happen when u install a program?
frosty berry
files get added to your system, mainly
placid torrent
so i can install something on x path, copy to an usb, from that usb to another computer
and i will keep working?
without reinstalling on the new pc?
stark prawn
If the files don't depend on other things on the pc
placid torrent
ty
stark prawn
And all references are relative
frosty berry
well, some files might not be installed directly in the directory you are looking at, on windows, the registry often contains information about the installed programs, the registry is files as well, but you can't just extract the part created by an installer for a program.
a lot of programs have "portable" versions that avoid these issues, and some program just work without any issues.
placid torrent
i knew about the portable versions, but lets say steam
the platform itself
it has more than the folder where i install it, right?

You should try Electron
vestal briar
Ew
undone berry
JS is overhated
stark prawn
JS isn't the reason people dislike electron
undone berry
Whats wrong with Electron?
vestal briar
Take etcher as an example
undone berry
Etcher has always been fine for me
vestal briar
Could have been easily made with countless ui frameworks
But they picked electron
So now the install size is 150mb (zipped) for no reason
stark prawn
Every electron app has it's own little chromium browser and nodejs inside
undone berry
Etcher is slightly annoying because quite often you're loading it for one thing
But for a music player
you launch it when you turn your PC on
and never touch it again
so who cares
its not that heavy
vestal briar
Mine will be hooking onto a browser
undone berry
For a music player I much prefer a dedicated app
vestal briar
The only thing that's actually running is a tiny python server with a list of album paths in ram
undone berry
rather than losing it in a mess of tabs
vestal briar
I can also just make a weird firefox window especially for it
Still hooks onto firefox instance but is standalone
stark prawn
app mode
vestal briar
Sure it'll take up a ton if you are not using firefox already but it's for fun
undone berry
Thats fair - and obviously for any project that you're making, use whatever you want to use
vestal briar
Basically what a progressive web app is
vestal briar
You want to see the world burn
vestal briar
Webapps are really cool, I just don't think the electron approch is good
stark prawn
My old laptop dislikes electron.
undone berry
I don't see anything wrong with it
stark prawn
It only has 6gb ram.
vestal briar
Much better just hooking onto whatever you already have installed
stark prawn
So just slack and discord already take up a chunk
undone berry
That sucks for current you
but future you will love having pretty apps
and not caring about the RAM usage
vestal briar
Is that a good thing?
undone berry
Its not a bad thing
compare discord to TeamSpeak
TS is great software
but it just looks ugly
and isn't nice to use
undone berry
Like what?
All I can think of is stuff like the win10 settings panel
which I definitely don't think looks great
vestal briar
undone berry
absolutely fucking awful
vestal briar
This will probably be an entire chomium installation somewhere
undone berry
A calculator is the kind of thing that I think should always be done in QT
it doesn't need to look pretty
but its also not an application you're using that often
undone berry
Yeah, I agree Etcher should be in QT or something
pine vector
don't forget the ads!
vestal briar
Discord is the one thing I can sort of say is the usecase for electron but even then
undone berry
But something like a Music player, or Steam, or uh - another app - should look pretty and be easy to use
and the best way to achieve that
is Electron
vestal briar
It could just be attached to a running instance
undone berry
You can just use Discord in browser if you want that
vestal briar
Rather than being your 3rd web browser installed locked down to discordapp.com
pine vector
hehe. so the ElectronVM? this sounds eerily similar to something. 😉
undone berry
I want disparate processes for different apps
vestal briar
You want a new web-browser install for each tab is what that sounds like
stark prawn
electron makes for pretty and easy to use apps? Not sure if electron has anything to do with that.
undone berry
I just don't care that its a different web browser instance
Electron lets developers use HTML/CSS/JS
which is where the best GUI stuff exists
vestal briar
Electron looks pretty but it's just a new web-browser install locked to a server thats running on your pc
undone berry
Who cares?
vestal briar
A progressive one is using a web-browser that's already installed to run the pretty thing
People that don't have money for massive computers
stark prawn
We are living right now.
vestal briar
And basically anyone who doesn't want to waste electivity
undone berry
Running electron apps vs native apps cost an entirely negligble difference in electricity
pine vector
at a micro-scale, sure. but multiply that by the number of PCs in the world....
frosty berry
i do believe it's easier to do beautiful apps in kivy than with web tech in electron, fight me 😄
vestal briar
I'm using 1gb of my 8gb on running 3 web browsers
undone berry
how much electricity do you think is wasted converting floats into json into their binary representations?
a lot
undone berry
or at least not a negligible amount
stark prawn
You'd think it would be harder to convert them to their string representation.
undone berry
I think there are lots of places to look before coming to Electron apps for saving electricity
to the point that
I think it is time misspent
if developers focus on that area
vs saving computing in other areas
vestal briar
Just a nice native framework or a progressive webapp can beat electron in basically every way
undone berry
There are no native frameworks that are near as nice to use as HTML/CSS/JS
vestal briar
Even with that argument
Progressive web apps are better
And you could easily make 90% of electron apps natively with some nice solutions
vestal briar
They are as fast or faster to make than electron apps in dev time
stark prawn
Plus pwa's can't access your system
vestal briar
And native granted won't look as nice as html but speedy as hell to build and is passable anywhere unless you explicitly need great design
undone berry
PWAs might be the answer
but I'm pretty sure stuff like complete QT desktop apps are becoming less relevant

I'm just having the most frustrating thing with instagram right now. Evidently my account's email has been changed. Trying to use the reset link does not work because the email has been changed. Trying to follow their site's instruction on how to report hacked account does not lead to anywhere. It just leads to their help centre page that says follow on-screen instruction. But the on-screen instruction just gives me direction to get to the help centre.
Apparently there is no real way to be able to email instagram directly either. So who here has experience dealing with instagram in situation like this?

for a real turning it off and back on again you need the restart option

Intel drivers are created by intel themselves and will be part of any normal distro's kernel.

You could use this as an excuse for trying clear linux

no clue, but iirc clear linux is made by intel and optimized for intel.

try i3
sand goblet
PLEASE CHARGE HEADSET
the problem with using i3 is I need something I can actually be productive in
and i3 is not it
I've been there
I'm using xfce right now
stark prawn
I installed it on laptop yesterday. overall positive so far
sand goblet
the plan I originally had was like
obviously I can't run dev tools on this
but at least I can have discord and such locally
but now I'm not so sure
discord is just about usable but it maxes out a core
that'd be fine at home where I have 8, haha, but not here
frosty berry
i've used i3 on laptops and dektops alike for 8+ years i think, the trick i guess is certainly to tune it quite a bit to suit your needs, at least for me, it's quite different from the base config. (most major change is using dynamicaly named workspaces, not numbered or fixed names worksepaces, it took a couple of scripts to get right, but it completely changes how i use it.)
stark prawn
I learn as I go.
Like: I needed a notification daemon
because libnotify just freezes for 5 minutes if there isn't one, everytime you get a ping
sand goblet
Yeah, i3 is like vim, it needs customising
that's something I don't want to spend a lot of time on
sand goblet
good for you, haha
stark prawn
This wasn't an i3 thing. Just that it's something that plasma usually took care of.
And the default i3 config is pretty good tbh.
rough sapphire
(and neither does vim, but I digress)
stark prawn
Once I get the hang of i3 imma enable vim keymap for vscode
rough sapphire
tools arent meant to be "intuitive", they're meant to get the job done as productively as possible
sand goblet
The point of something being intuitive is that someone can be relatively productive from the start and build on the more advanced concepts as they go
stark prawn
These tools have a steep learning curve
sand goblet
And if you can't do that then.. Provide a tutorial like emacs does
stark prawn
You can play one of the vim games
sand goblet
And present it front and center so I don't have to go looking for it
frosty berry
pretty well known i guess but still https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ffarm4.staticflickr.com%2F3109%2F3251176498_c3485a55fb.jpg&f=1&nofb=1 😛

stark prawn
IDE's are generally super easy to start with, but have enormous functionality.
Especially with plugins
sand goblet
Yup
stark prawn
I still learn daily about vscode
sand goblet
I still regularly discover IDEA features
rough sapphire
i dislike when people dare make bold statements about things or tools they've only tried once
sand goblet
Well we live in a user-oriented world
You can't blame people for liking their user-friendly intuitive tools
rough sapphire
liking one thing doesn't mean other people can't like something else
sand goblet
Well, I don't think anyone said that
rough sapphire
I have nothing against vscode, visual studio, or other IDEs whereas you have a lot to say about i3 and vim
when in reality they are superb tools
sand goblet
Are you seriously getting salty about "i3 is not intuitive"
Are you sure you're not the one with the problem here?
You don't have to twist that into "oh apparently I'm not allowed to like i3"
rough sapphire
you call it "unproductive" when it's the no1. productivity tool.
and apparently "help, I dunno how to use it" = it's bad
frosty berry
yeah, i think gdude just said " It wasn't intuitive enough for me" which is fine, even i disagree it's the best thing to look for
rough sapphire
The point of something being intuitive is that someone can be relatively productive from the start and build on the more advanced concepts as they go
@sand goblet
the problem with using i3 is I need something I can actually be productive in
@sand goblet
sand goblet
Yes, I said those things
rough sapphire
you're implying it's impossible to be productive in i3
frosty berry
but still, that's weird to state that you can't be productive on it, it's more like you don't want to.
sand goblet
No, you're reading into a sentiment that wasn't there
Everyone is productive in their own tools
That's why they use those tools
I would hope that was painfully obvious
This is why I hate trying to discuss usability improvements to tools like this
frosty berry
these tools are quite important for us, so making statement about them is dangerous 🙂
sand goblet
xx is no newcomer to the internet
and I don't think it's unreasonable to ask for this kind of tool to include a basic tutorial of some kind anyway
tame terrace
I can't be productive in i3 either. hey there's two of us.
sand goblet
I'd like to use i3, but I can't get my head around it
I would have found emacs equally unusable if it didn't have a tutorial haha
stark prawn
tbh my plasma workflow was already very similar to i3
tame terrace
there are probably tutorials on the world wide web if you were so inclined.
sand goblet
yes, but why do I have to go searching for them?
sand goblet
because the tool is deliberately designed not to be intuitive, it's designed to be productive - as previously mentioned
you're going to need a tutorial
tame terrace
I think this is a silly idea. There are tons of tutorials out there, whether they ship with the tool or not seems irrelevant
sand goblet
also, i3 is a WM, so if you're using it and you don't know how it works, you probably can't look up a tutorial yourself
rough sapphire
intuitivity and "user-friendliness" can and will eventually become a limiting factor to how productive and efficient you can get with it
sand goblet
I don't entirely disagree with you @rough sapphire
tame terrace
I'm not really motivated to run through a tutorial to learn i3wm, but that's on me, I don't really hold that against the tool. Maybe if I did, I'd fall in love with it. many of my colleagues have.
but I guess I'm already too pleased with my desktop environment to really care.
it's solving a problem I just don't have.
stark prawn
Depends on what you do with it really.
tame terrace
my windows tend to stay in the same place more or less all the time
I think i3 is a great productivity tool if you've got limited screen real estate
perhaps less so on a super ultra widescreen monitor
probably great for laptops on the go, perhaps less so for desktops that never get rebooted.
stark prawn
switching workspaces, opening programs; that's pretty much what I did in plasma and now in i3
sand goblet
I don't even use workspaces, yeah
tame terrace
yeah, I don't really understand why I would switch a workspace. I can fit everything on my screens
sand goblet
I do appreciate tiling WM features
but I tend to add those to cascading managers
rather than go full tiling
tame terrace
I use gTile for tiling, and it works quite well for me.
stark prawn
snap to sides is a standard feature in modern de's
sand goblet
it's a bit more involved than that
tame terrace
that's true, but on a super ultra widescreen you need more tiling options than snap
sand goblet
I like that aquasnap lets me grab a window boundary and resize all of the windows at that boundary at the same time
tame terrace
I need at least 3, often 4 or 5 windows sharing that screen
stark prawn
I can imagine doing something silly like 2 windows vertically split.
frosty berry
i mean, i3 has a doc page, which is not very long, and explains all the features
sand goblet
I usually have 3-5 windows on my left monitor, yeah
frosty berry
tame terrace
..not very long?
frosty berry
ok, it's a tad long
frosty berry
but code examples takes more than half of it, you can skim it 🙂
tame terrace
so you use i3?
tame terrace
and whats your monitor setup like?
stark prawn
.... I copied some parts of your config and didn't add attribution 😦
tame terrace
I practically never work on my laptop alone.
frosty berry
i have a key binding to move a workspace to "next screen"
so when i'm on multiple screens, i can easily organize like that
i think that's the only thing i really needed to adapt to a multiple screen setup
frosty berry
i was actually reluctant to move from wmii to i3 years ago, because the tags tied to a screen, not common to both, so when you changed tag, it only changed it for your current screen, and you had to go to the other screen and change this one as well. had the habit to have one browser window for almost each tag, and have it on the second screen, for docs and the stuff, but wmii was dead in the water, and i3 was where the action was, so i ended up switching, and i must say it works out really well this way too, it's more like gnome does (or did?) it, you can use the second screen as a more fixed one (tough you can change it easily), and switch more often the main one.
sand goblet
Why do they call alt mod1? I guess so you can rebind it?
rough sapphire
yes
frosty berry
i bound it on "super"
rough sapphire
the default is Win, but you can bind anything to anything
rough sapphire
can be alt as well
those are the two common defaults
depending on your kb layout
my old laptop worked a lot better with alt as mod1 because of the placement of the Fn button
stark prawn
It's alt
stark prawn
If you first launch i3 it will ask you which you want.
sand goblet
Ah okay
stark prawn
The default is alt, not win
frosty berry
the official name of this key is "super"
stark prawn
In their terminoligy they call it 3 different things depepnding on os. command for osx
frosty berry
ah meta confused me a lot at first
sand goblet
So, to switch between the terminals, use $mod+k or $mod+l. Of course, you can also use the arrow keys.
just on their own, or with the modifier?
frosty berry
with the modifier
it would be pretty bad to steal the bare keys from the window
i mean, you basically never need the arrow keys, but still.
(you do if you use a word processor, i guess)
pretty sure only the first 3 sections of the docs are really needed to get started btw, so it's not that long.
sand goblet
aside from the keybinds I don't think this gives me much I don't already have
but it definitely seems much, much lighter
frosty berry
it sure is
sand goblet
Would be nice on a low-spec laptop like this, I think, barring other alternatives
it's not that I never saw the appeal, though
frosty berry
well, there are other lightweight alternatives, i liked fluxbox for quite some time.
sand goblet
Oh yeah, I've used fluxbox before
frosty berry
it's certainly less weird
openbox is a good bit nearer of a common desktop experience
and still pretty light
sand goblet
it's interesting that I basically ended up shoehorning most of the i3 featureset into windows
I guess the advantage is that i3 comes with that stuff
stark prawn
If you go i3 I would advice to install a program launcher along with it
frosty berry

Okay so I have concluded some things while doing Project Euler
While working on Problem 5, where the goal is What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20, I have found a few interesting things
First, my original solution was as follows:
found = False
current = 21
while True:
found = all([current % num == 0 for num in range(2, 21)])
if found:
break
current += 1
print(current)
This method took around 7 and a half minutes to complete
So then I got to thinking, what if I cut down on the number of numbers it had to check. So I stripped it down a bit, and came up with this:
found = False
current = 21
while True:
found = all([current % num == 0 for num in range(20, 10, -1)])
if found:
break
current += 1
print(current)
This put me at roughly 4:45 or so. To speed this up a tad, this is what the fastest solution I came up with was
found = False
current = 21
DIVISORS = [num for num in range(20, 10, -1)]
while True:
found = all(current % num == 0 for num in DIVISORS)
if found:
break
current += 1
print(current)
By defining all the numbers to be checked ahead of time and by removing the brackets to make it a generator rather than a list comprehension, I managed to bring it down to around 2 minutes and 10 seconds. Still slow, and I want to improve it, but this taught me a couple of things
-
When determining multiples like this, if you're starting from 1 up to a range, you only need to do the upper half, since anything below that would already contain the various multiples of 2. Might need additional tweaking on that thought.
-
When using
all(), and you know that there are going to be a bunch of things that will be knocked out, use a generator rather than a list comprehension. That lets it short circuit and save a fairly substantial amount of time. -
Again regarding using
all(), make sure you put the things most likely to cause a short circuit near the front, so that you're having to check less things per iteration. -
Make your list of things to check before hand. That saves on having to generate the new set of things to check every time
Like I said, I'm sure there's a better way than what I did, but I found it interesting that I was able to shave a little over 5 minutes versus my initial solution.
This has been another episode of Hemlock's Ramblings
Oh holy crap
Okay, so I happened to have PyPy on my system, figured I'd give that a shot
The solution that took 2:10?
10 seconds in PyPy
That's friggin nuts
undone berry
Cpython is just complete trash for these algo problems where runtime matters
plucky ridge
Well sure but I didn't expect PyPy to crush it that hard
Yeah that's just friggin' wild
plucky ridge
In situations like this yeah
Where there's obvious repetition
I just want to understand how it does it like that
Just seems like magic
rough sapphire
can you show the code for that
i wanna try pypy too 🙂
@plucky ridge do you have some magic to get those timed automatically
or is it in the scripts
plucky ridge
Oh nah. I just did datetime.datetime.now() before and after
Subtracted the start from the finish
Not the sturdiest way of testing it, but this was more for my amusement and curiosity rather than a rigorous testing.
rough sapphire
well you get a clear difference still
plucky ridge
Oh absolutely
One sec, I'll show the current full code I have
import datetime
found = False
current = 21
DIVISORS = [num for num in range(20, 10, -1)]
start = datetime.datetime.now()
while True:
found = all(current % num == 0 for num in DIVISORS)
if found:
break
current += 1
finish = datetime.datetime.now() - start
print(current)
print(finish)
Yeah nothing fancy
Running that through standard CPython gave me the 2:10 to around 2:14, whereas through PyPy it gave me 10 seconds
rough sapphire
the same here
but it's not weird that pypy is faster imho
it's doing actual compilation of the code
plucky ridge
Oh I'm not surprised that it is faster, just how much faster
plucky ridge
I'm sure it could be nice and quick in Cython as well
I might have to futz with that later
rough sapphire
#include <iostream>
#include <chrono>
using namespace std;
int main () {
auto start = high_resolution_clock::now();
bool found = false;
int curr = 20;
int divisors[10];
for (int i=0; i<10; i++)
divisors[i] = 20-i;
while (true) {
curr++;
for (int n=0; n<10; n++) {
if (curr % divisors[n])
break;
if (n == 9)
found = true;
}
if (found) break;
}
auto stop = high_resolution_clock::now();
auto duration = duration_cast<milliseconds>(stop - start);
cout << duration.count() << endl;
cout << curr << endl;
}
the moral of the story is that while pypy is really fast, there's still room for improvement
oh nice is that java or C#
wait its C#
🤷♂️
imagine coding C#
not in the rude way imagine but like the actual imagine
like imagine coding it and having memory leaks for days
yes, C++ is not for the novice.
graceful basin
with std::unique_ptr, it is not as bad
rough sapphire
wrote that code above and didn't leak memory once, YUSS
whats the difference between c# and c++ like fr
C# is for humans. C++ is not.
graceful basin
C# is not a bad language
rough sapphire
they are very different things although they started closer together than they might seem as of 2020.
HolyC is the best language trust me
only scrubs cant code holyc
im going to be called a racist now 😦

Got the audio player actually retrieving and displaying song info on page
Not using database because for this it's easier to store in memory right now for a basic demo
It doesn't work because the audio location is supposidly invalid
But when you copy the URL of the audio player bit at the bottom and put it in a new tab, it works perfectly fine

Do I need to either be on Linux, or have an intel cpu to use virtualised stuff for Android Studio?
undone berry
I think I'm being dumb. I really can't figure out to to use an Android Virtual Device in Android Studio. I found this, but everything I do seems to tell me I still need HAXM which I don't think I can install.
I found this, but apparently I'm dumb and can't figure out what its actually telling me to do, I enabled the windows thing and think I have all of the prerequisites, https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html
The important part is i'm on a Ryzen CPU
Windows 10, Android Studio 3.5

@undone berry I had the same issue. Switching to mac fixed it
undone berry
I have Ubuntu installed, I guess I'll just have to switch to that for Android stuff
vapid bluff
i dont know how to fix this specific issue, but there are other ways to run an android emulator than AVD
undone berry
I just want the green button in Android Studio to work
vapid bluff
it will work if you have an android device hooked up via adb
it doesnt matter what that device is, where it's running
could be an android x86 installation running in vmware for example
or if you have an android phone, you could just hook that up
undone berry
alright sure - do you have any reccomendations for another emulator?
vapid bluff
ive had success with the images here https://www.osboxes.org/android-x86/
there are some programs out there like bluestacks, genymotion, etc that are essentialyl android emulators with some bundleware
could look into that as well
nox is another one
undone berry
Oh actually - I heard about Greymotion during my search as apparently good
I'll check that one out (actually it was bluestacks I'd heard of)
rough sapphire
i have android x86 running on oracle VM
its basic. and no shitty software ads from 3rd party
but i use scrcpy to access my real life mobile when i need to

yeah windows phone ftw
ok any ideas how can i relay notifications . device info on wifi ?
use adb ? android . or make a app with notification access ??

adb can relay a lot of thing tho
a software even relay screen and i can even control it

gentle moss
that's why you should always self-organise your mp3 collection
vestal briar
Yeah
gentle moss
i strip all ID3 tags and organise through folder structure
vestal briar
Trying to get to the point of rythmbox
gentle moss
that way, if i ever want to organise them, i can use the folder structure i've made to re-id3 tag mp3s
Artist / Album (Release Year) / (Tracknumber) - (Trackname)
vestal briar
This would be so easy if they where all artist -> albums -> tracks
But some of them are this shit
How am I meant to classify that
gentle moss
:|
vestal briar
Hm what about just a folder structure with each level having different names
If there are 3 levels of recursion, artist -> album -> track (mp3)
If there are 2, compilation -> track (mp3)
If there are 4, artist -> compilation -> album -> track (mp3)
gentle moss
well @vestal briar
they're all albums with unique names and release dates
that's why /<Album name> (<Release Date>)/ works fine

Is there a way I can make Linux Mint look like Windows?
stoic abyss
There should be a theme or something
rough sapphire
Hm, themes?
stoic abyss
Search on Google I'm sure there are a guide when I get home I will try to find out and send it to you
rough sapphire
Thanks, didn't knew you could install themes.
stoic abyss
Ye, don't remember how exactly since I don't use mint like year ago or smth but you can install themes
sand goblet
Kind of weird to want it to look like windows, though
that'll just confuse you more
I suggest the Arc themes, particularly Arc-dark - that's what I usually use on Linux
rough sapphire
I- just switched to Linux, and I already want my Windows back.
wheat lynx
Why did you switch to Linux in the first place?
rough sapphire
Cause Windows was being weird and didn't allow me to wipe the C drive.
ahahaha
Thought it would be fun to try Linux.
sand goblet
It would be fairly weird for it to allow that
sand goblet
The major difference between linux and windows in that regard
windows will stop you from deleting system files
linux won't, it'll just break instead
rough sapphire
Fucking Windows.
wheat lynx
You should be able to reset windows...
sand goblet
You can easily reset windows in the recovery options, yeah
rough sapphire
I'm gonna commit apt remove root
wheat lynx
or at least reinstall it from usb if it is conpletely ruined
rough sapphire
@sand goblet, @wheat lynx but it returns an error after the Asus screen shows 40% it boots into Windows advanced options and when I click Continue to Windows boots and bam! Returns an error.
rough sapphire
What's that...
sand goblet
well some machines come with an OS installation DVD
otherwise you have to make it yourself while the OS is still installed
rough sapphire
Nah, my laptop had just Windows 8.1 installed.
sand goblet
also sometimes laptops come with a recovery partition
rough sapphire
And I tried to make an iso file from another laptop, it appears to be corrupted or not burned to the usb.
Well it's a 7 y/o laptop, wdym.
It's old and hardware also needs an upgrade, the hard drive is fucking loud and makes streetch sounds some sort.
sand goblet
well if you told the linux installer to wipe and use the entire disk, then you already destroyed any recovery partition that might've been there
sand goblet
OK, well that isn't what I said
rough sapphire
I mean, it asked wherever I want to use the c disk as the partition disk, I selected yes.
gentle moss
yesterday i linked you instructions on how to do a windows recovery
and it sounds like you've just straight up wiped the partition while trying to install linux
there's no "recovery" from that unless you have the installation media
rough sapphire
I mean, yeah Windows is not there anymore, got my Linux account password reset and the sudo password.
I tried to boot from a Windows iso file later on from a usb stick I used to boot into Linux.
Didn't work.
Just booted me into Linux.
Even if the first choice was the usb stick.
sand goblet
did you use the same usb port?
and did you watch for the "press enter to boot into..." prompt?
gentle moss
also you need to make sure you mount the iso properly with something like rufus
rough sapphire
Bios?
sand goblet
bios?
sand goblet
I think someone pointed out yesterday that you had a misunderstanding relating to what a BIOS actually is
so how would you define it?
rough sapphire
@gentle moss I installed a Windows tool from Microsoft's site, it said that it burned the iso to the stick, not sure.
sand goblet
You could still do it from linux if you can get a copy of the ISO
rough sapphire
lol imagine not knowing what the bios is
A motherboard prompt thingy where you control everything from CPU to OS???
sand goblet
using balena etcher, not rufus
sand goblet
it's an electron app, which is a legitamate complaint for a tool like this
but it's pretty good
and cross-platform
rough sapphire
If I wiped my Windows, the license isn't there or it's stored in a variable somewhere on hardware?
gentle moss
7 years old laptop? probably not storing keys in UEFI.
sand goblet
rough sapphire
Well, good for me I can get a license for free.
sand goblet
I have had laptops far older than that that stored the key that way, Bisk
far, far older
gentle moss
maybe i'm forgetting how old uefi is
sand goblet
pretty old
gentle moss
time flies when you're tech support for free
sand goblet
but I mean the feature itself isn't actually a uefi exclusive feature
dell BIOS do it as well
gentle moss
yeah, i wasn't aware many others did the same
since it requires a custom bios, most are pretty standard
rough sapphire
Well since I got a way to change my sudo password I can atleast access the os apps.
Might aswell stick around with Linux.
rough sapphire
how do i add an extra line to my table in html
like a vertical line
in the middle
sand goblet
Add more cells, I guess
rough sapphire
cells?
sand goblet
Yeah

whats cells
sand goblet
Rows contain columns of cells
sand goblet
just add another <td> in each row
sand goblet
what, you want the line to like, pass through content in the table?
rough sapphire
yes
sorry im afrikaans so my english is shit
i want a line to go through the whole page of all tables
in the middle of the table
sand goblet
I can't think of an easy way to do that
sand goblet
Well I guess you would have to somehow create an absolutely-positioned element that floats above the table, of the correct width, height and positioning, that looks like the line you want
I honestly can't think of a good way to do that
rough sapphire
i shouldnt have said i can do this shit

sand goblet

rough sapphire
but i noticed it now only
sand goblet
I checked out Matrix the other day (via Riot.im)
It was quite a nice experience but I don't think it's as user-friendly as it could be
I think my biggest complaint is how it deals with rooms vs communities
rough sapphire
how do you mean
sand goblet
well, if rooms are channels and communities are servers
Let's say you wanted to recreate this server on Matrix
So you create a community, go to add rooms, type in a room name and.. "Can't find room, try a Matrix ID"
it turns out that you create a room separately from a community, and then you can add that room to the community afterwards
rooms in a community don't have any kind of centralised permissions either
rough sapphire
that's an architectual issue, not an implementation one
due to the decentralized nature of matrix
sand goblet
I don't think decentralisation makes that impossible
and it could be worked around in the client
a side effect of this though means that, if you're in a lot of rooms from a lot of communities
your home screen contains all of the rooms you're in
and it's not obvious at all where they come from
so you'll end up with eg an Announcements room for every community you use
rough sapphire
🤔 my communities are grouped
