Could wrap in a function that will throw or return

Just.. Write a function that returns what you pass it if it isn't an error
rain spindle
function createdbb () {
var result = r.dbCreate('haste').run();
if ( result instanceof Error ) {
console.log("Already created db...")
}
}
Like that?
sand goblet
No
rain spindle
I want to just stop r.dbCreate('haste').run(); from erroring at all
I'm running this code on every start
sand goblet
just write a returnOrThrow function
rain spindle
var r = require('rethinkdbdash')({
servers: [
{host: 'rdb', port: 28015},
]
});
r.dbCreate('haste').run();
r.db('haste').tableCreate('uploads').run();
Should this at least run in order?
Because even this code errors.
I think its going faster than the DB can keep up
sand goblet
It's probably callback based
Or maybe it uses promises
You'll have to read the docs
sand goblet
Try the sync module from npm
rain spindle
Ok, thanks
var Sync = require('sync');
var Create = function() {
r.dbCreate('haste').run();
Sync.sleep(1);
r.db('haste').tableCreate('uploads').run();
}.async();
Create();
A bit like that?
wet steppe
no dont like
shell blade
oh y is that?
stark prawn
It's okay, apart from the really creepy laughs at the intro
shell blade
lol
wet steppe
I can't really say why I don't like it
more that
it doesn't have content that I do like
tame terrace
@shell blade it's ok. some of the tracks from the album are a lot better. it's a bit too safe chord progression wise to be great but the production on stuff like xanny is pretty interesting.
I feel like she would've been much better off at a different label.
something more alternative
kind of a shame imo. but hey, she'll probably be far richer with this one.
glass gorge
I've seen plenty of junkies whip out a wallet filled up with 500/1000 kr bills
tame terrace
@clear flame I would feel profoundly uncomfortable without my wallet.
glass gorge
coins, yeah thats gone :βΎ
wooden silo
I haven't used a wallet in like 5 years.
tame terrace
I just keep my drivers license and credit and debit cards in it
and the rfid card for work
wooden silo
But I do have a phone jacket with some compartments for cards and small pieces of paper.
glass gorge
I keep my keys in my wallet as well, can't go anywhere without it
tame terrace
a tiny bit of cash in case of APOCALYPSE
potent tangle
have you guys heard of those card holders
wooden silo
I figure that by the time the apocalypse happens, fiat currency will be just as useless as my card.
tame terrace
what bothers me though is when people have their debit card in their phone covers
wooden silo
@potent tangle My wife has a card holder.
tame terrace
I think those card holders look really posh
wooden silo
What's wrong with having a debit card in your phone cover?
tame terrace
well first of all most of them have magnets, which is a bad idea.
sand goblet
oh god, I don't get people that put their debit card with their phone either
especially when the phone already does nfc payments
tame terrace
but also it's a matter of like.. losing your entire life in one fell swoop.
wooden silo
If I lost all my cards, I could replace them in like a week or less.
And I can block them in 15 minutes.
sand goblet
I've never lost a card so I don't have a single clue how to replace one
tame terrace
yeah but you have to realize they're gone first.
wooden silo
As for the magnet, that's only bad for the magnetic strip, and I virtually never swipe the strip anymore.
I'm also not convinced the magnet is even strong enough to erase the strip, even if exposed directly for an extended period.
If I lost my phone, I'd be aware pretty quick.
It's like being naked nowadays.
tame terrace
I guess that's all fair.
lilac glade
I feel that way about my wallet, not my phone.
sand goblet
Our ID cards here are magstripe
and I have ruined one before by keeping it with my phone
wooden silo
My driver's license has a qr code.
tame terrace
..for what?
lilac glade
When I was getting numbed up at the dentist, he finished and told me to look at my phone for a few minutes while waiting for the numbness to kick in.
"I don't have my phone."
"You wanna go get it?"
"Nah."
wooden silo
For identification.
sand goblet
I was gonna say that's a novel use of a QR code
wooden silo
They scan it when I pick up a package at the post office for example.
sand goblet
but QR codes are only used in novel ways
tame terrace
that's not novel, that's genuinely useful
sand goblet
yes, which makes it novel
I wish people actually used QR codes for something useful here
they're great tech
summer rampart
there was a guy that had a QR code tattooed onto his skin that linked to a youtube video
tame terrace
oof.
summer rampart
after he posted the picture of the tattoo people got the video taken down I think
sand goblet
that's the internet.
rough sapphire
That is nothing.. I know for a fact we have some gravestones with QR codes in Norway too.. Like oke.
vapid bluff
invention idea: retractable phone lead in your pocket, like one of those extendable dog leashes
wooden silo
He should've linked it to a domain name he owned.
vapid bluff
you hook it up to your phone with a special case or something and that way if you leave it on a chair or something itll zoom back into your pocket when you get up
lilac glade
zoop
tame terrace
you'd need some loose-ass pockets
summer rampart
wait aren't there like wallet chains that are made out of rubber bands that do the same thing?
wooden silo
Yes, there are.
sand goblet
phones are heavier than wallets though
wooden silo
I'm sure this exists already.
vapid bluff
ill sue them for stealing my idea π
vapid bluff
that i just came up with 2 minutes ago
rough sapphire
Do you guys wear watches still?
sand goblet
I have a huawei smartwatch 2
wooden silo
I wear a mi band.
lilac glade
I want to get an NFC band.
summer rampart
my daily driver's a 7 year old gshock
sand goblet
One of the reasons I wanted it was for Google pay
vapid bluff
i keep an old tiny digital watch with no wristband in my pocket as a spare timekeeping device
tame terrace
I don't wear a watch.
sand goblet
Which worked initially until Google decided it shouldn't be available in my region yet
vapid bluff
like a 21st century pocket watch π
sand goblet
Despite totally working fine on my phone
lilac glade
Neither do I, lemon.
I do, however, wanna play with NFC a bit.
wooden silo
I use mine for date and time, and for setting reminders
tame terrace
maybe you should get a chip injected
rough sapphire
A smart watch I can understand, but an actual watch I is like a wallet for me at this point, pointless imo
summer rampart
was going to suggest that lemon haha
lilac glade
Troll some friends, try some Win10 authentification, amiibo stuff.
summer rampart
go all hackerman
wooden silo
I don't know about pointless. I primarily use the mi band for telling the time and that's still useful.
summer rampart
from what I've seen it still looks iffy/icky though
lilac glade
A lot of things that can go into NFC, all with a nice wristband.
wooden silo
It's much more convenient than getting the phone out of my pocket.
tame terrace
I don't wanna marry NFC
I just wanna inject it into my fleshy bits
those rings look quite nice.
lilac glade
That's... okayish.
rough sapphire
@wooden silo Fair enough, but yeah.. Phone is my watch
vapid bluff
straight into the veins
lilac glade
Not a fan of making a Terminator just yet, though.
sand goblet
I have a first model one from the original kickstarter
vapid bluff
gotta get that nfc high
sand goblet
I didn't find a use for it yet
sand goblet
I was going to use it to share my contact at coderdojos
But nobody had phones with NFC yet
tame terrace
you can pay with nfc almost everywhere here in oslo
sand goblet
Same here, but there's an annoying problem
When you pay with NFC by card, there is a β¬30 limit
There is a limit with google pay
but
tame terrace
our debits cards have nfc now, though, so I don't use my phone or anything.
sand goblet
nobody knows what it is
and it's higher than β¬30
my bank says there isn't a limit on google pay, but some terminals won't process it anyway
but other banks don't say
vapid bluff
you dont even need credit/debit cards any more, some banks let you sue your card through your phone via nfc
use*
sand goblet
that's google pay, yeah
vapid bluff
oh i didnt know google had a thing for it too
id trust the bank's own app over google pay tbh
wooden silo
In Sweden we have this thing where you can send money to a phone number via an app.
It's basically replacing all instances of transactions where there's no card reader.
vapid bluff
is it made by the government?
wooden silo
It was created by a group of six of the largest banks
rough sapphire
Norway too^
vapid bluff
thats neat
rough sapphire
It's honestly so good and it's instant more or less when transferring money
vapid bluff
whats the input like? can you scan a qr code or something?
or do you have to manually type in the number
wooden silo
No, you type in a phone number and an amount
You previously linked it to your bank account
rough sapphire
You enter a phone number (I believe it can only be norwegian) add amount + message -> send and done
tame terrace
yeah that's gonna take off in more countries. norwegians and danes are pioneering that particular type of fintech
it's gonna be huuuge
vipps and mcash and so on
vapid bluff
hmm, typing in the number sounds like a bit of a hassle
summer rampart
m'cash tips nfc ring
tame terrace
hahaha
vapid bluff
and mistake prone
rough sapphire
You can allow it to pull contacts from your phone too
tame terrace
it's not mistake prone, it resolves the number into a name.
wooden silo
It's also only used for those cases where you can't pay with a card.
tame terrace
and a phone number is far shorter than a bank account number
wooden silo
So it's not like you have to stand in the store and type in their phone number.
tame terrace
you type the number and the app basically goes "oh okay, so you want to send 50 euros to DANIEL MANSWORTH?"
and you say yep yep
and then it's done.
you don't need to know shit except the number. which you might already have saved.
rough sapphire
Great for splitting the bill for beer and pizza (you can call me POC)
tame terrace
yeah or splitting the bill for 10 bottles of hot sauce
vapid bluff
person of color?
tame terrace
like me and @viral parrot did recently :D
wooden silo
The times I've had to manually enter a phone number is when I go to like an open air market and buy some handmade piece of jewellery, and the craftsperson put a little sign with their number next to their wares.
tame terrace
yeah

proof of concept?
rough sapphire

tame terrace
hey awzkum what do you work with my dude?
rough sapphire
As of now I'm an RPA developer in TromsΓΈ (robotics processing automation)
rough sapphire
I was honestly kind of shocked to hear your accent on your hot sauce video, I had no idea you were norwegian π
tame terrace
well I'm a special case, I barely speak norwegian at all.
I know how, I just don't use it much.
I speak english at home, with my kid, at work..
lol typo
rough sapphire
Do you have that issue where you know the English word, but not the Norwegian? Haha
tame terrace
that's like my default state
I think entirely in english
I talk to myself in english
(oh yeah I talk to myself a lot)
no no I'm not crazy I'm just rubber ducking
wooden silo
I speak some Swedish at work, but that's it.
Besides that it's pretty much all English.
rough sapphire
That is so interesting. I'm really looking forward to see how things will be 20 years from now in Norway in regards to that
tame terrace
my fiancee is the same, we exclusively speak english to each other and we're both norwegians. my dad is american but he honestly doesn't feel much like one.
I doubt it's just the two of us
I guess it's because we sort of grew up online
wooden silo
Oh, you're both Norwegian?
That's a bit unusual.
My wife is Paraguayan, so that's why we speak English.
tame terrace
yeah soaf is norwegian through and through, but she gets upset if I speak norwegian to her. "it sounds fucking stupid. don't do it."
wooden silo
Hah. Norwegian is so cute, though.
tame terrace
some dialects, maybe.
wooden silo
Now I wanna hear that.
viral parrot
What what?
viral parrot
Pinged?
rough sapphire
Not recently(?)
viral parrot
Cant find it, mobile just went off

No you pinged eivl earlier when we spoke about Vipps, so nothing important
viral parrot
Oh, yeah it's great
rough sapphire
Yepp. You got Swish, yeah?
wooden silo
Yep
rough sapphire
I see. Anyways, I have to run so you guys have a good day. Fun talking π
wooden silo
Later

the company that made vipps asked me if I'd like to work there once.
they use a lot of python
wooden silo
It feels like they ought to be able to pay well
tame terrace
yeah
fintech and medtech are the places to be nowadays, from what I've heard.
over here in oslo
both frequently use python in their stacks, too
wooden silo
Yeah, I would guess they're both pretty big over here as well
Seeing as how I'm going from one fintech company to another at the moment
vestal briar
Medical stuff is intresting
I think someone here or an old friend done like a laser heart rate detector
Really cool

huh
google earth's measure distance algorithm treats earth as a perfect sphere
i.e. the distance between two points on near exact opposite sides of the earth is 20015.12 no matter what direction the line goes
instead of being shorter over the poles and longer on the equator
makes sense - ellipse arc distance is much harder to calculate
wooden silo
You'd think Google would manage, though.
And is it that much harder?
Isn't there a simple analytical formula?

Greetings all!
wet steppe
hi
ember pebble
Fairly new to Python but not scripting in general, and I'm having a lot of fun with it.
Good to see there's a healthy Discord server
wet steppe
what sort of script do you write
ember pebble
Right now I'm automating data onboarding for the company I work for
So initially they used vba and sql
wet steppe
are you using like numpy and scipy and stuff
ember pebble
Take x files and combine them and reformat them for data warehousing then create the load files for the application and then etc etc etc
Yes
Numpy, Pandas, and next project looks like vendor is transitioning to xml for their data files
wet steppe
what sort of data is it π
ember pebble
I don't see much xml resident in Pandas but maybe it doesn't matter
There's no read_xml function
Etc
But there's the minidom so I've been reading up on it
And maybe it can piggy back
Just clunky and possibly a little slower
Thankfully the files are only tens of thousands of lines
Json is fun
I've used it more for web services things
wet steppe
yeah its popular for web these days

..man, dunnes stores controversies
In September 2011, The Irish Independent found that Dunnes Stores was selling bra-and-knicker sets for three to six-year-old girls. Dunnes also has padded bras for girls with a 28 to 30-inch chest, which are the typical measurements of nine-year-old girls.
what even
grave phoenix
?
sand goblet
it's a controversy relating to the sexualisation of children
weird that I didn't hear about it, it was probably all over the news in '11
grave phoenix
But is just bras...
sand goblet
It's probably because girls that young don't need 'em typically
apparently the dunnes ones are lacy as well
yeah, it's probably not as much of a deal now as people made it out to be 8 years ago, but it is an interesting thought experiment
you have to wonder where the demand came from
vestal briar
https://drewdevault.com/2019/03/25/Rust-is-not-a-good-C-replacement.html Wow look at this horribly written article
has many competing compilers. They all work together stressing out the spec, fishing out the loosely defined corners, and pinning down exactly what C is. Code that compiles in one and not another is indicative of a bug in one of them, which gives a nice extra layer of testing to each. ...Isn't this a bad thing?
And they list safety as a downside?
wet steppe
enforced safety is actually a downside in certain situations
vestal briar
Rust actually has a pretty admirable selection of supported targets for a new language (thanks mostly to LLVM), but it pales in comparison to C, which runs on almost everything. A new CPU architecture or operating system can barely be considered to exist until it has a C compiler. And once it does, it unlocks access to a vast repository of software written in C. Many other programming languages, such as Ruby and Python, are implemented in C and you get those for free too.
This same thing applies to rust
@wet steppe Rust enforces by default, you can easily turn it off in scope
wet steppe
okay that's good
vestal briar
It's just a generally bad thing to do
Unless interacting with some weird C/C++ code
Actually I am not sure if all C/C++ code is considered unsafe in rust?
tired osprey
@vestal briar it is obviously considered unsafe, c++ and c an not provide the safety mechanisms rust can at all (well they can with lots of effort but rustc cant be sure wether they actually did)
vestal briar
I was talking more if there was like a flag with rust to tell it that it is safe
vestal briar
π
I am not sure if it would even work that way
Without some pretty large rewriting
Oh well, I have much to learn
tired osprey
and on that enforced safety thing, for example in embedded environments I can just write checks own code
acr.acr().modify(|_, w| unsafe {
w
.latency().bits(acr_config.0)
.wrhighfreq().bits(acr_config.1)
});
and the rest of the again checks code 502 lines of code in that file (except the other few ones with unsafe) are safe and guarantee all of rusts benefits to me \o/
tired osprey
I can tell you that to a certainty of +- 10 min
vestal briar
Sure π
tired osprey
I started learning rust at the 4th of november 2018 at around 7:20 pm so that makes around... 6 months 10 days and 1 hour
vestal briar
Cool
It's been about 7 months of Python for me now
Before that I done a bit of C# until I was ok at it and dabbled a little in python before
tired osprey
and by now Ive written at least 1644 lines of rust which are uhhhh useful? in some way at least
vestal briar
Nice :D
I probably have ~500 lines in production but plenty more in html+css (have been doing a website for the last 3 months)
tired osprey

Oh it's like a motherboard name ;)
tired osprey
whats a motherboard name
tired osprey
hey if you want to I can explain that name to you in detail :P
vestal briar
I'd love not to
I need to learn Rust then embedded :P
I'll guess at the name, stm is the manufactors initials, 32 is 32-bit, some hexidecimal stuff and then hal is I forgot what hal is
tired osprey
aw π¦
wet steppe
I want to learn rus
robust sierra
helo
tired osprey
stm is the manufacturer
32 is indeed 32 bit
h as in high performance
7 because uuh the f7 was their last chip with high but not so high performance iirc
and then x as in plug a number
and then 3
and then you can also stick some characters like ZI and shit there which show if it has builtin cryptography and whatnot
and hal is hardware abstraction layer
robust sierra
helo nix
tired osprey
hello person
vestal briar
Ahh that's it
robust sierra
how does one create ai regime
vestal briar
I knew it was hardware
I was thinking hardware accelerated language, not that that makes sense
tired osprey
i think at the point I said embedded the majority of people did :P
oh that hal thing
vestal briar
I have a little electronics kit but no way to power it
Apart from jankily wiring up an rpi's gpio
tired osprey
you can get one of these fancy stm32h7 nucleo dev boards (which take ages to order) and power it with a mini USB π
wet steppe
LOL you can control rpi gpio with node https://www.w3schools.com/nodejs/nodejs_raspberrypi_gpio_intro.asp
tired osprey
nah just kidding there is apart from my project only one rust crate for this chip (which implements the GPIO which you guessed it i stole) and then there is stms code generator in C which (at least i heard that from people using it) is not so nice to use
@wet steppe its just an access to a file on linux, you can control it with bash if you want to
tired osprey
that depends on the chip
for an arduino youd use the arduino ide which uses avrdude which.... does some USB black magic
vestal briar
Hmm
tired osprey
for my chip its really fancy
wet steppe
arduino ide π€
tired osprey
for my chip it goes like
the chip circled in the upper is actually a full blown chip itself which can be communicated to in several ways including
openocd
tools by stm
and others
and then you communicate to that chip (which is also the on board debugger) to the lower, bigger chip to upload your software
wet steppe
do you make robot, nix
vestal briar
(FYI I don't know what half of this means π )
tired osprey
no I make, well program, stuff for a project which gets put into a can sized hull and then shot up around 700 m into the air because why not
vestal briar
Damn
tired osprey
and you run rust on an arduino by using another rust compiler I forgot the name of as rust does not support AVR assembly as target yet (and AVR assembly happens to be the one to run on arduinos)
and for this chip (which is a cortex m uhhhhhhhm 7 i believe) you simply choose the thumbv7em-none-eabihf target together with a bit magic from already existing rust libs and you are done
wet steppe
gets put into a can sized hull and then shot up around 700 m into the air wow I was never gonna expect that π
tired osprey

vestal briar
Another bad joke
wet steppe
same
wet steppe
what book though
tired osprey
yah borrowing
wet steppe
ok whoops i reacted slowly
vestal briar
I got stuck on it with c++ when I started programming
I understand it mostly now
Will spend a couple days just on this topic
Just a ton of new words with similar but really diffrent meanings
tired osprey
eh its just
Each value in Rust has a variable that is called its owner.
There can only be one owner at a time.
When the owner goes out of scope, the value will be dropped.
vestal briar
A variable is a pointer to some bit/bits of memory stored in the stack of heap
A pointer/refrence/etc is a pointer to a pointer (variable) that points to that imaginary thing and is always stored on the stack
If I want to make it confusing for myself ^
Yeah, some bits just confuse me when putting pointers in with ownership
I think I understand pointers/refrences now though
vestal briar
Mm
tired osprey
wrong thing
vestal briar
tired osprey
no no it blinks but speshal
vestal briar
Ok then
tired osprey
there is a hardware thing running in the background resetting the code afte exactly 500 ms if it is not resetted itself
that way one can avoid software crashes (well not avoid them but restart the software if they happen)
and it just took me two days
vestal briar
So everything is done in so much less then 500ms that there is plenty of time to reset
Damn
vestal briar
Huh
tired osprey
the code is basically
led high
wait 1 second
led low
enable thing
loop {}
Ah
tired osprey
and then as the loop doesnt reset the watchdog the watchdog resets the software which causes the thing to blink
and if i but a reset for the watchdog in the loop the LED stay low so it actually works
and also that thing can be clocked at up to 480 mhz if you want it to so it can do a lot of thigs in less than 500 ms
vestal briar
That seems quite large for a little-ish chip
tired osprey
the default is 64
tired osprey
hey that chip is really a powerhouse
vestal briar
Would it need any cooling?
tired osprey
nope
tired osprey
wait let me grab that demo stm always makes to show it off
https://youtu.be/Ab2SbAOTTQI?t=59
they always show off how its built in jpeg processor can do 4 24 fps videos at the same time with barely any cp usuage
vestal briar
Damn
tired osprey
its probably total overkill for what we are doing
were just processing two camera streams in real time and some sensory stuff
vestal briar
How powerful is it compared to an audrino uno?
tired osprey
an arduino uno is an 8 bit microcontroller clocked at up to 20 mhz which has barely even a fraction of the features implemented in hardware this one has
vestal briar
That should be fine source: nothing but will probably run a bit high on cpu
Oh wow that's pretty poor
tired osprey
it still fits lots of shit though
vestal briar
Yeah
wet steppe
20 mhz
tired osprey
yes
vestal briar
Little cheap, versitile board that is a popular all-rounder?
Good Β£8 clone of it?
tired osprey
also if you want a realyly poor one checkout the attiny series of atmel it has like 8 pins, depending on the version somewhere between 512 to 16 kb (yes kb) of program memory
vestal briar
Only 16mhz
vestal briar
hmm?
tired osprey
the chip can technically take 20 but its clocked around 16 here
vestal briar
Ah
vapid bluff
what can you do with 16 mhz
vestal briar
Though that weak one you mentioned (attiny series of atmel) sounds like a fun challange
tired osprey
@vapid bluff what can you not do
vestal briar
Trying to get something decently complex run on something so little
vapid bluff
play crysis?
tired osprey
that is out of scope for them
vestal briar
I wonder how big the linux kernel is compiled π€
tired osprey
depends on what you include
vestal briar
I imagine there are some laughable minimum requirements to run a kernel
vapid bluff
is there an os running on that 16mhz chip
tired osprey
you can get linux down to 10mb if you actually want to
vestal briar
Nice
tired osprey
and of course its not meta
that would be a waste of resources
you can however run an RTOS on the bigger one above
vestal briar
How does it work then?
tired osprey
but dont have to
vapid bluff
so it's basically as bare metal as it gets
vestal briar
Is it cross-compiling sort of thing?

how does it work well you give it your program, flash it into its flash memory via avrdude and then it starts executing it
yes

Rust is exacly what I want
A systems programming language that has good docuentation and isnt convoluted
With mostly hands-off memory management
That works well with c and c++ but can also interact with python
wet steppe
sounds more like you want Golang
it has a garbage collector so no manual memory management at all
and very good docs
vestal briar
Also it's pretty weird that there is a full programming language that is pretty cool being used almost exclusivly for gtk design π€
tired osprey

not cause i need an energy drink, but just cause I want one
@shell blade dont' want to be the paranoid one here. but maybe that phone wasn't lost , it was stolen. i mean it's possible someone found it after 3 months. but it just sounds conspicuous to me. like maybe he was holdiing on to it seeing who calls it, or looking through pics or some shit
idk. i am just not a trusting person.

vestal briar
I want to learn some CS and Rust instantly
Then I can do some projects that I like to do
tired osprey
@vestal briar why exactly do you need cs for your rust projects?
vestal briar
Mainly learning some more CS stuff to get to know about memory management more
wet steppe
learn C
tired osprey
hm I wouldnt say memory management falls under cs and you dont really need to care about memory mangement in rust either
like im doing bare metal rust with only the cortex m crate providing a minimal basis and not even i have to care about it
sand goblet
Is rust stack or heap?
tired osprey
both
sand goblet
Figures
tired osprey
but in bare metal its mainly stack
you can however define heap allocators if you want to
and then there is also the heapless crate which basically provides all the relevant heap datastructures but (you guessed it) on the stack
wet steppe
Python's runtime only deals in references to objects (which all live in the heap): what goes on Python's stack (as operands and results of its bytecode operations) are always references (to values that live elsewhere).
vestal briar
I would like to do C later on but I think doing Rust will give me some better low level practises
I can read C but not write it kind of thing

Are there side effects in the condition of that empty while loop?
tired osprey
side effects?
vestal briar
It takes time?
tired osprey
yeah its supposed to take time
vestal briar
Now thats stupid
tired osprey
its waiting until some register values changed to some other register values so it can do new stuff with other registers
vestal briar
So how does it get a var passed through
tired osprey
so what UDRE obviously stands for is "UART Data Register Empty" and that means that if UART Data Register Empty is 0 the UCSRA (which obviously stands for UART Control and Status Register A) gets logically ANDed (if thats how you say it) with 0b1 otherwise 0b01
vestal briar
Also is ```
while(!(something)) {}
// stuffor
while(1) {
if(something) {
// stuff
}
}``` better
Top looks janky but it's bad having an if statement

qucik question, just to confirm. Is encoding the process of taking something physical and converting it to digital format?
like for example coverting a sound wave into mp3 format
?
sand goblet
Not necessarily
wet steppe
encoding is much more general than that
sand goblet
it's basically just converting something from one format to another
physical is still a format!
but it can also refer to embedding something within something else of another format
it's actually really tricky to define
I guess usually you use it to refer to the way something is represented
a string may be using the UTF-8 encoding

By late 2019, Psyonix plans to release the game on the Epic Games Store. According to The Verge, at that point Rocket League will no longer be available on Steam. According to Epic, all existing Steam copies can expect continued support. Neither company disclosed the terms of the deal, including how much Epic paid to acquire Psyonix.

In regards to the article linked earlier about the epic store hijacking Rocket League from Steam. I was about to blow 60 euro on Anno 1800 - Then they removed it off of steam. Now I won't even bother looking it up even if on sale. Exclusive titles can kindly fuck off and go back to being a console thing imho. π

Having providers that had a lot was nice for a while, but with more streaming services entering the market as well as gaming platforms, that's probably going to be a thing of the past soon.
sand goblet
Competition is good and I don't mind store exclusives
But I don't like when games that are already available become exclusives
And I don't like epic store, it's not well made and a touch insecure
oak tangle
I'm not sure if exclusivity really works well when it comes to competition
We'll see how the streaming market evolves, but I'm not sure it'll be beneficial for us consumers
viral parrot
it most certainly is not
oak tangle
Before long, we'll need 100+ euros packages (think cable providers) for different streaming providers because all 10 of them have small fragments of the market
viral parrot
exclusivity is by design not customer beneficial
sand goblet
I don't think it makes a huge difference on PC
The price still has to be competitive or sales will be bad
In this case, epic is also putting pressure on valve
I don't think valve will do anything
Even if epic said they'd stop doing exclusives if valve lowered their cut
oak tangle
I guess the gaming business is different, because you're not buying all-inclusive package deals
You can buy a couple of games on steam and epic
sand goblet
On console, that is kind of a thing
oak tangle
Yes
sand goblet
It does exist on PC too
But that's on like origin and the humble store
Oh, and PS live thing
oak tangle
Those are still not subscription-type stores, right? Not too familiar with them, but you still buy single games or bundles of games?
sand goblet
And soon we'll have stadia and the xbox service
They're all subscription style
But aside from humble, you immediately get access to a ton of games
I think sony's model is the most interesting
Because if you have a fast enough connection you don't need a PS4 to play PS4 games

do steam keys bought before a game becomes unbuyable on steam work?
if so then there could be people stockpiling rocket league keys, selling them for a markup

this happens, there are websites that live on this practice and ignoring that you are not allowed to resell the keys
