they call them AppVMs
you start an app, it opens in a workspace for that AppVM

There's a good level of separation between your hardware and the VMs too
So you don't have to worry about being compromised and your microphone/webcam/etc being used against you, like you would normally.
sand goblet

Heyoooo!
plucky ridge
I just remembered what I was going to ask
I'm waffling about something on my Game of Life thing. Lazy me wants to make the edges loop around, since that'd be easiest to implement. Has anyone seen one like that? Would it be true to the point of the exercise?
undone berry
As in you want to look at the eight neighbours of the cell?
plucky ridge
Yeah
undone berry
if so, you can do it with an offset generated by two range()
plucky ridge
Or are the edges of the grid considered dead?
undone berry
You can loop the edges with modulos
plucky ridge
Well again it's not can but should
undone berry
I've seen both ways. I think both are acceptable
Linking edges is cooler I think, but the other way is pretty easy as well. Its just a big if statement
plucky ridge
Yeah for sure
Although, I guess I could do one of each
Nothing really stopping me from doing that
rough sapphire
@plucky ridge the answer to that is basicall N/A
as GoL is meant to be simulated on an infinite board
and as such there are no "edges"

without Vue I don't think I'd have enjoyed this so much
I added like 4 features today alone haha
odd thorn
Yeah, the right tool changes the job’s annoyance level significantly.
sand goblet
Yeah, absolutely
though there's still some jank in there I haven't quite figured out yet
like this eyesore of a function https://github.com/TeamJM/webmap-client/blob/master/src/main/js/journeymap.js#L344
vestal briar
Bad function but variables make it a hell of a lot easier
sand goblet
I honestly have no idea how to clean this up
vestal briar
Probably the best you can do with that many variables

Unless you fragment all the cases? But then it'd be mostly useless functions

well see the problem is
not all the information I need is exposed by the api yet
like those TODOs there, I can do nothing about that because I don't get a dim list

Looking at both of these things and I feel like there's almost certainly a neater way to do it - but I can't see what it is at all

although I dunno how much JS Mystic knows
I really need to fix that documentation, as well..

@sand goblet: Set all the icons to the inactive form before the switch, then only change one of them to active inside?
odd thorn
Least they won't be in the switch, since they (can) happen regardless of the case.
Might not make sense for the nether, but at least for the end it makes sense, since that's happening for multiple cases.
odd thorn
It seems like it might make sense to handle the nether without a call back to the function, but I'm not sure if that would really help. Everything else would either have to be in a big else clause, or you'd have to set the datastore.state values and currentMapType there, too.
sand goblet
The problem with end and nether is right now I'm just doing it by dim ID
which works for vanilla
but I can't distinguish between dim types otherwise
odd thorn
Actually, that could make sense.
odd thorn
Np. Also, now that I think about it, you can replace both nether checks by just directly setting datastore.state values and the currentMapType, then returning, which actually should make it a bit more compact.
sand goblet
There's a lot of duplication if I do that, though
although, hm, yeah
I guess I don't need separate vars
odd thorn
i.e.
if (this.currentDim === -1) {
datastore.state.dayIcon = dayIconDisabled;
datastore.state.nightIcon = nightIconDisabled;
datastore.state.topoIcon = topoIconDisabled;
datastore.state.undergroundIcon = undergroundIconActive;
this.currentMapType = mapMode;
return
}```Not really much more than the second check, and you get rid of the first.
Plus, stops that tiny bit of wasted time when you are in the nether.
sand goblet
actually that won't entirely work
well I guess it would work for the nether
unless you clicked on the "underground" button
but I can just remove the mode check and always apply it
yeah, that'd work
End has to sit as it is though, yeah
odd thorn
Yeah, but the end check is shorter anyway.
odd thorn
Hm. Might be a bit cleaner to override that in the day case directly. Not much, but would prevent those couple of checks from happening twice.
Not a big deal either way, though.
odd thorn
Fun times.

Does ubuntu run mainly on Python3.6? Because I accidently changed the alternatives to python3.7 and terminal didn't open up anymore. I recovered it successfully, thankfully.
I mean not mainly, but system applications
plucky ridge
@polar vigil Yep, both Linux and Mac heavily use Python for various system stuff
That's why in general you want to stay away from updating your system's version, and install using your package manager or something like pyenv to keep everything separate. Odd that 3.7 broke it, though. I can't think of any major removals or changes that would prevent 3.6 from working
Or no wait, was that the one with the major async changes....
polar vigil
Maybe, because it didn't let me open anything.
frosty berry
you can type ctrl-alt-f1 to open a TTY and fix things from there, to come back to graphical mode it's alt-f7

i think it was more probably about a library not being installed for 3.7, that it needed

I had used pyenv, but I don't know what I was thinking

rather than something in python itself

I also say C#, but that's primarily because my first language I learned in college was Java, and C# is essentially a cleaner version of that

i don't know either of them well, but i would also bet that C# is easier
c++ is a very big language, with lots of things you can get wrong, while C# is designed more recently, in a more focused way, and do things in a way to remove some of the issues you could have (managed memory for example).

I'm not sure what kind of a loop you want me to do in Rust
like a while with a counter variable to recreate the incrementing for loop?
this is bad? for i in 0..10_000_000
odd thorn
More the 2..limit
odd thorn
Try a mutable iterator instead.
plucky ridge
Would that not cause more overhead?
jagged fog
I get it faster by 0.08s if I switch the for with while
for the mutable you mean I set limit as mut? @odd thorn
I got a warning and 0.2 slower
or you mean i I'm not sure how either of those would do something
plucky ridge
Is that speed increase consistent across multiple tests?
That .08 sounds almost negligable
jagged fog
nope I checked for more iterations it varies a bit so it's negligable
plucky ridge
Makes sense. I would have figured the two would have been optimized down to be about the same thing
rough sapphire
Makes
sensecents
Fixed that for you
odd thorn
@jagged fog: No, not limit. i.
I replaced the for loop with:
let mut i = 2;
while i < limit{
if number % i == 0 {
return false
}
i = i + 1
}```ah I see what's causing the confusion
I pasted the wrong time for rust, that's old time. The current time is very similar to C time
and no that didn't make any noticable difference
odd thorn
That does explain a lot.
jagged fog
ikr, my bad
odd thorn
Happens to all of us sometimes.
Course, you can cut all those times in half pretty easily.
jagged fog
I was using u128 and that takes like 3-4 times more
odd thorn
(The time can be cut in half by checking if the number is even once, then check the range starting at 3, and going up by 2.)
jagged fog
sounds like a interesting perk of algorithm, I didn't know that
jagged fog
that works very well yes
but now I have a huge mystery, the old way in Python took 113s, your way (with literally 2x less numbers to check) is 103s... so only 10s difference 
and at first I was like what kind of science is this but yes now it makes sense... if it's even ofc it's divisible by 2 thus not a valid one
welp I guess it's to do with the curve and how most of those numbers make no difference for speed until we get to big ones
nvm got it
odd thorn
It doesn't seem unreasonable.
frosty berry
pretty sure that's unrelated, minmax is not ML at all
though i'm not an AI expert at all
gusty oar
its some kind of AI but seems true
odd thorn
It's not neural-networky AI. More video-gamey AI.
odd thorn
Whereas new-style AI is, er, black magic.
frosty berry
the general principles don't seem overly complex, but the way they are used and the resulting artefacts seems quite magic yes
odd thorn
On some level, it's evolutionary theory in practice, so it's not exactly surprising that it's hard to pick apart.
frosty berry
that's a nice way to see it indeed
odd thorn
Minimax isn't too hard, especially for something like tic tac toe. I'd suggest just seeing if you can understand it, and if not, asking particular questions.
(Also, fun variant you can try to code when you're done with tic tac toe: tic.)
(It's like tic tac toe, but both players are x, and whoever gets three-in-a-row loses.)
gusty oar
if current board state is a terminal state :
return value of the board
if isMaximizingPlayer :
bestVal = -INFINITY
for each move in board :
value = minimax(board, depth+1, false)
bestVal = max( bestVal, value)
return bestVal
else :
bestVal = +INFINITY
for each move in board :
value = minimax(board, depth+1, true)
bestVal = min( bestVal, value)
return bestVal```for example what is terminal state
and maximizing player
odd thorn
Terminal state = Board where the game is over.
You assign one player to be the maximizing player for minimax, which means, if they win, you score the board positively.
The other one is the minimizing player, which means, if they win, you score the board negatively.
gusty oar
who is AI there
odd thorn
Doesn't matter too much. This is just analyzing the board for optimal play.
Minimax is basically just the process of thinking:
"Ok, if I go here, then the other guy wins right away, so don't do that. But if I go here, he has to let me win."
gusty oar
i found some tutorial about minimax but he's doing it with js
idk js
still can i understand 😄
odd thorn
Once you know how to code, it's not too hard to follow what other people are doing, at least when the languages are similar.
gusty oar
hmm js and python seems similar
btw once past i made NXN tic tac toe. this algorithm only contain 3x3 doesn't it ?
odd thorn
It should be generalizable.
vestal briar
Yay, made the basics of that quick vm thing I was talking about
Just need to do the majority of the api so it actually makes the vm

serene zephyr
Aaaaah my tooth aches
sinful turtle
if I wanted to might an AI for something more complicated like a fighting game how should I do it?
rough sapphire
just visited the website of the people who hacked Facebook's twitter account
"professional" and "whitehat" in particular made me lol
vestal briar
Wouldn't you think that "elite" hacker groups would know some website design
White background on white text
solid pollen
Being an hacker doesn't mean that you know rules of good design :P
gusty oar
idk about hackers but usually pirate groups doesn't have website
so usually pirated software download sites named hacker groups is scam
(and game ofc)
i want to try that minimax
still i don't get all of idea but never hurts to try
frosty berry
if you die in minmax, you die in the real world!
(yep, try things, even if you don't understand them, that's half the fun :))
gusty oar
😄 why algorithm seems hard
vestal briar
Ubuntu server, what is wrong with you?
I setup Ubuntu server and it gave incorrect login no matter what correct password or login I entered
Tried again and I have the same issue
gentle moss
pebcak
rough sapphire
tty?
vestal briar
Hm?
rough sapphire
are you trying to log in via getty
vestal briar
Nope
rough sapphire
ssh? use keys
vestal briar
Got a monitor and keyboard directly connected right now
rough sapphire
... that's a tty
rough sapphire
root account?
gentle moss
plus since you have physical access you could boot in single user mode and manually change the password for that user
but i've installed ubuntu server loads of times and never had this issue
vestal briar
Yeah but if I have to do that then theres something underlying
rough sapphire
or just boot off an usb and chroot into the real install
vestal briar
Same here
gentle moss
i stand by the pebcak
gentle moss
well if you can't login then you can't lspci to see if it's detected the network adapter
vestal briar
Yeah
rough sapphire
ip a
deft musk
Um hello! Sorry to disturb off topic but am I supposed to ask for help in any of the channels under "Python Help"?
rough sapphire
does your network adapter appear in th elist
vestal briar
I'll try and install again and see if 3rd times the charm
rough sapphire
@deft musk aye
royal lakeBOT
Bad argument: Converting to "int" failed for parameter "seek".
vestal briar
Don't want to be using a broken install on a hands-off server
deft musk
Okay thank you!
vestal briar
@rough sapphire Unless I boot through grub I can't possibly have access
gusty oar
how indie game devs finds original idea
for example SUPERHOT
how they found such an original idea
gentle moss
try using a tripod, it might blur less
vestal briar
Shh
Needed to capture before next startup screen
So what I'm getting is that this server has something slightly wrong in bios and the install magically doesn't work
vestal briar
bnx mips something
vestal briar
Also looks like dl380 bios requires a warrenty
gentle moss
broadcom NetXTREME network chips
vestal briar
Yep
gentle moss
you'll just need to get the firmware and put it in place
vestal briar
Looked on the site but it's asking for some warrenty stuff
Probably not on the right one though
gentle moss
after that i think it'll just sit in a folder in the /lib/firmware dir
you should have enough information now to google a more detailed answer though
vestal briar
Wonder why it isn't working now though, last install was perfectly normal
And login is still broken, time to use grub
hollow leaf
You got a UART of any kind?
gentle moss
it's a server, why would you connect to UART?
and no, it doesn't have UART
DL380's a chonky boy. you get it 2nd hand?
rough sapphire
@hollow leaf uart probably still drops to a getty nowadays
hollow leaf
Sorta worn, and I knew that UART is a getty.
😕 didn't know the problem but I just threw a thought
gentle moss
fair enough
just seems like the 18.04 install doesn't have the firmware for the broadcom netEXTREEEEEEME network chipset
vestal briar
Finally got logins working after changing in grub
vestal briar
@gentle moss got it for free 2nd hand
gentle moss
Gen 7?
hollow leaf
Usual Broadcom 😛 Had to deal with a USB wifi chipset that had no FOSS driver
vestal briar
One psu was broken on an otherwise perfectly fine server and they just refunded due to shipping costs being too high
Yeah, g7
vestal briar
E5620s and 24gb
gentle moss
i was using it as a router for like 9 months
vestal briar
Mine isn't too bad, 120w idle and ~500-600w max I recorded
Hm, looks like it is already installed?
sand goblet
lspci will show all devices, if it isn't in there at all then it isn't plugged in properly or something
If it is and it isn't working, you probably don't have the kernel module for the driver loaded
gentle moss
it's an onboard network adapter in a server
sand goblet
Then it'll be in lspci won't it
gentle moss
you'd assume
sand goblet
There's also lsusb if it's in one of those weird onboard USB headers
gentle moss
for a gigabit network adapter i think that's unlikely
sand goblet
You'd be surprised
gentle moss
maybe you need to modify the conf and add the fw to it
sand goblet
Yeah, also worth a go
vestal briar
Looks like it recognises it in lshw
gentle moss
try adding bnx2 to the dracut.conf
add_drivers+="bnx2"
into the file and then dracut -f
then reboot
vestal briar
Don't think dracut is installed
rough sapphire
i mean it definitely shows up
sand goblet
Autoconfiguration failed? Hmm
I mean I guess that means you need to configure it yourself
gentle moss
could be just that, yeah
it throwing up firmware errors on boot is still strange though
vestal briar
No idea what port its plugged into on the server so it'll be pretty hard to configure
vestal briar
I just have like 4 white ports and 2 black
Blacks say iLO and whites just have the eithernet logo and a number
gentle moss
that number is the port number
and they'll be initialised in order
enp3s0f0 is first
gentle moss
they're management ports
it's an isolated network for controlling the physical server
vestal briar
Gotcha
quasi lance
cough
rough sapphire
welcome back @gentle moss where you been
vestal briar
Using some old 2008 microatx home pc as a janky server for now
odd thorn
Decides to try spacemacs again
Opens up standard files for current project
spacemacs lags to inoperability from the data file
Goes back to neovim.
sand goblet
Yup, it's fairly slow for use
frosty berry
it's interesting how emacs slowness has kept up with the technology
vestal briar
Mm, 2nd server that isn't working with ethernet
Starting to think its something to do with the powerline adapter I have but it's showing no errors when plugged into desktop pc
gusty oar
interesting and tricky question
frosty berry
hm, i might be missing something but it seems pretty straightforward to me
didn't do java seriously in a long time though
frosty berry
a
i don't see any difference between the first and second test aside the spaces around == and i don't see how that would change the logic at all
round rose
gusty oar
We always thought that whenever two object references are compared using “==”, it always evaluates to “false”. But here Integer caching changes the results.Integer class has a caching range of -128 to 127. Whenever a number is between this range and autoboxing is used, it assigns the same reference. That’s why for value 100, both num1 and num2 will have the same reference, but for the value 500 (not in the range of -128 to 127), num3 and num4 will have different reference.
in java == compares two object
frosty berry
but == doesn't compare equality between integers?
gusty oar
.equals() compare values
frosty berry
yeah, this language deserves to be shot 😛
gusty oar
😄 i thought first this too from python
for example in java we can say int $_ = 5
java allows it
tired osprey
naaaah java doesnt deserve to be shot for its comparing mechanism
there are other reasons though
polar vigil
AI is really interesting, I probably focus on that this year
@sand goblet You will never find out if I am a bot or not
sand goblet
But the question is, do I care?
polar vigil
No
sand goblet
Dun dun dun
gusty oar
who is fan of Apple
sand goblet
🦗
rough sapphire
@polar vigil It's weird you'd ask that to a bot
gusty oar
i love apple @sand goblet do you love
sand goblet
Nope
gusty oar
why not
sand goblet
I don't love
rough sapphire
I think apples are pretty great. Oranges can be annoying though.
All that peeling
sand goblet
They really love scalping their users with their accessories
Especially airpods, goddamn
rough sapphire
@sand goblet You don't like having a mouse you can't use while it charges?

sand goblet
iOS absolutely does have viruses and exploits
It's just a BSD after all
Pretty much all jailbreak tools make use of exploits that could just as easily be used maliciously
Early jailbreak just used PDF exploits
gusty oar
none of antivirus company has ios antivirus
sand goblet
Well yeah, obviously
Apple wouldn't want to ruin their image by allowing that
What browser do you use on iOS?
gusty oar
i heard apple doesn't allow app interaction . so app cannot much do if it contain virus
safari
sand goblet
Indeed, that is the correct answer
Because despite other browsers existing on iOS, they're all really just reskinned safari
sand goblet
In fact all third party apps have to use an older version of safari for their webviews than the version in the actual safari app
Because as we know, apple hates competition
sand goblet
It's pretty garbage compared to what we have on android
I use Firefox on my PC and goddamn it I use the exact same browser on android with the exact same extensions
Imagine being able to install ublock origin on a mobile browser
Apple doesn't want you to
Imagine being able to FIX YOUR OWN PHONE
Imagine fixing phones for a couple of your friends and Apple suing you into the ground for it
Fuck that
Let's make people buy expensive lightning adapters instead of letting them use their existing USB-C chargers that every other phone has
sand goblet
Let's release a laptop for professionals and give it no USB ports
gusty oar
apps does have right to publish their ads
sand goblet
With a keyboard that breaks if a single crumb gets under it
Let's make overpriced wireless earbuds and not give people a wireless charging case, or allow them to start an assistant when paired with a non-apple device
gusty oar
😄 they are greedy right
sand goblet
Let's introduce proprietary extensions to wireless security protocols because we don't like wps
Let's deliberately slow down older devices without the users' consent (they were just convicted for that in France)
sand goblet
They did it in the first place.
Let's force people to buy an expensive computer from us if they want to make apps for our mobile devices
gusty oar
does we have to buy latest mac for xcode ?
sand goblet
Let's prevent other music platforms from competing with apple music by forcibly taking a larger cut than usual from their IAPs
gusty oar
hmm apple music actually good service
sand goblet
I think I've made enough points by now
They do so much shady shit and they don't redeem themselves afterwards
They don't believe in value for money, they don't believe in the concept of owning your own devices, and they don't want people to be able to fix their own problems
gusty oar
but this problems actually include many big companies
it called capitalism
nvidia for example does similar things
sand goblet
When has Microsoft stopped you from installing windows on any device you can get it to run on?
When has OnePlus tried to stop you from rooting your phone?
gusty oar
ah micro$oft
their update policy
ah making me crazy
broking working devices
and forcing people to buy new devices (to killing windows 7)
making heavy windows 10
and killing old computers
sand goblet
okay, about half of those things are fallacies
but even if they weren't, they're not comparable
if you buy a windows machine, it doesn't have the RAM soldered to the motherboard
in most cases, anyway
sand goblet
if you buy an android phone, you can install whatever you want on it, you don't have to use the play store - or any store at all if you don't want
you can run an android phone with completely open source apps and no google apps at all
and you don't need to buy a chromebook to write apps
gusty oar
yea in my old samsung phone
android came with samsung apps
and i couldn't even delete
sand goblet
huawei makes good phones, but there are no google apps anymore
thanks to the US trade ban
oneplus phones are great because they're very easy to customize
sand goblet
I have root, yeah, via magisk
gusty oar
hmm i heard magisk put ad
sand goblet
nope
gusty oar
when i had android . i was doing root via odin
sand goblet
I like how the oneplus update app detects that I have root and downloads a full OTA instead of a partial one
gusty oar
it was hard tho
gusty oar
i got softbrick when i first tried
i was 14 or so
7-8 years ago
they ban huawei for tracking people
but microsoft does same
this trading ban was ridiculous
sand goblet
There wasn't really any concrete evidence for that iirc
I do have a huawei mate 10 pro sitting in a drawer here, it's what I had before I got my current phone, a oneplus 7 pro
gusty oar
idk but huawei accused of that
but microsoft,apple etc . is tracking
its nearly true
for example telemetry services in windows
if i wasn't gamer i would definitely use linux :d
i hate windows
odd thorn
I actually don't have many games that don't run on linux. But I don't play many AAA games.
sand goblet
I like Windows
There's been absolutely no evidence that the telemetry submits anything worth being concerned about
there's just a lot of it
gusty oar
i don't play too but i like some of AAA
especially i like few game companies (rockstar,cdpr etc.)
other than i play indie
and windows is greedy about ram
if you don't install windows on SSD and if you have ram less than 12 gb . windows will sure about making you hard times
