@BlueEyedBeast It's Downgaot

ETHproductions

I wonder if there's a query for users with the lowest question downvote-to-upvote ratio

ais523

cast, or received?

ETHproductions

20:02

Received on questions

ais523

it'll probably be for someone who's made a few uncontroversial answers, with a ratio of 0

really popular answers tend to receive random drive-by downvotes from people who don't really know what they're doing (this is a common problem on most sites; on SE it's less of a problem because downvotes require and cost rep, but it still happens from time to time)

Martin Ender

@ais523 you also don't have the required reputation for downvoting if you've never contributed to the site, which helps (but probably also skews the total votes quite substantially).

TuxCopter

@wat >_>

ais523

@MartinEnder that's what I meant by "require rep"

that said, contributing is a common reason for downvotes on many other sites

Martin Ender

oh, I only read the "cost rep" part, sorry

ais523

on Reddit, posting almost anything will immediately get you several downvotes, from bots/scripts who are trying to make their own votes count double (and effectively be able to vote on their own stuff) by downvoting everything they don't upvote

@TuxCopter D:

20:09

on Slashdot people often use downvotes to bury things they disagree with even though voting is very expensive on Slashdot (even with very high karma and moderator karma, you'd be lucky to be able to cast 2 votes per day)

downvotes were reserved for the sort of thing that would lead to "offensive" flags on SE

back when I was active there, I used to use my limited supply basically entirely on upvotes

as such I ended up in the habit of basically not downvoting anything ever

(on Slashdot, three net downvotes is enough to hide basically any post; two from a new user, one from an anonymous user)

mınxomaτ

I doubt slashdot will let users bury news from their own publications such as sf or softpedia.

Those of you who work in an office-like environment, about how much of your working hours are meetings?

Gabriel Benamy

20:32

Very few

mınxomaτ

A few minutes whenever most people are in, usually in the morning. But we don't have fixed office hours.

ais523

it really depends on your job, I think

DrMcMoylex

@Kade 0

ais523

when I work on research compiler development, we're talking about one hour a week, there's no real reason for more as it's a very solitary job that doesn't really require collaboration

Gabriel Benamy

Also depends on what you count as a "meeting"

ais523

20:32

many jobs require more though

DrMcMoylex

But then again, I'm 19 and an intern there, so...

Kade

I have anywhere between 1 and 3 hours a day :/

@ais523 This was a research position or a development position? It sounds pretty interesting!

Nathan Merrill

@Kade 15 minutes daily, 1 hour a month

Dada

@ais523 you work on compiler development?

ais523

@Kade: it's a bit of both but more development

I've just accepted another job in the same field, it's not that large a field though

DrMcMoylex

20:36

Huh. Well I just found a vim bug.

ais523

the basic idea is that when someone comes up with a new idea on how to write/design a programming language (this is fairly common in CS departments)

someone needs to actually try it out, trying to implement the compiler, writing programs, and the like

it's a hard job because you don't know for certain that what you're trying is even possible; you're the first one to do it

but it can be a lot of fun

Kade

So you're working with brand new languages then?

I sort of assumed it would be existing languages and compilers

ais523

often yes (sometimes the language is an existing one but you're implementing features into it that it doesn't naturally have)

Nathan Merrill

so your job is to break a compiler?

ais523

well, to take a concrete example, one task I was given was because my boss had developed a new method of compiling higher-order functions into hardware

we needed a new language for that, as there weren't any hardware-specific functional languages yet

and I needed to write a compiler (into VHDL in this case) pretty much from scratch

Nathan Merrill

20:39

oh, so you write compilers

ais523

and of course there are a ton of subtleties you get in practical implementation that you don't think of when writing up the maths

so yes, it's mostly compiler development, but with a different "focus" from normal compiler development

given that what you mostly care about is trying to get the program to work at all

once there's a working research compiler you can move on to trying to make a more practically usable one

Nathan Merrill

what do you compile into?

(typically)

Dada

@ais523 I'm actually looking for an internship on compilers or virtual machines... any chances there is an opening around you? or would you know where I could look?

ais523

so far I've only worked on hardware, so VHDL

with the new job I don't think it's been decided yet

Nathan Merrill

looking up vhdl...its pretty high level

ais523

20:42

you have to use a fairly low-level subset of it for it to actually be compiled to hardware though

Nathan Merrill

ah ok

Kade

In terms of a path to follow in university (I'm 3rd year), what would you suggest and what did you do?

ais523

@Dada: I can't think of an opening around me at the moment; half the reason I'm on PPCG right now is that I was looking for a way to waste some time between jobs, it took a while for the new one to start after the old one ran out of funding

@Kade: I did a PhD in theoretical computer science, that seems like a good path to follow (I also did a masters degree first but it was in electronic engineering; that's how I got into the hardware-focused jobs that I started with)

Nathan Merrill

well, my interest in compilers is more around high-level languages (specifically typing), which is probably stuff you don't have to deal with at all :/

ais523

that's what my PhD was on

although it was in the context of finite-state type systems

i.e. type systems that statically require a program to be implementable on a finite computer

Dada

20:45

@ais523 ok, I just asked in case you had an idea :)
may I ask where you work, out of curiosity?

ais523

university of birmingham, UK

Nathan Merrill

@ais523 there's a type system that allows for unimplementable programs?

ais523

@NathanMerrill most do, e.g. untyped lambda calculus, or simply typed lambda calculus + fix

you can write an infinite recursion in either of those

that's unimplementable on a real computer because the stack overflows, which is not a correct implementation of the program

Nathan Merrill

ah, so a type system that isn't recursive?

ais523

as such, we normally (theoretically) define the implemented version of the language to be only an "approximation" of the mathematical language

BlueEyedBeast

20:48

@ais523 I visited on an open day this year

ais523

disallowing general recursion is one thing you typically have to do in order to keep a language finite-state

Gabriel Benamy

oooh I just found a wild Pichu

Nathan Merrill

or a type system that prevents stack overflows from occurring at runtime?

ais523

it's not the only thing though

@NathanMerrill right, in my finite-state type systems stack overflow at runtime is one thing that can't occur (memory exhaustion at runtime can't either)

Gabriel Benamy

<-- is not just on codegolf at work, but is also playing pokemon moon

Nathan Merrill

20:49

I'm confused as to whether you're preventing infinite recursion of the program or infinite recursion of the types

but it sounds like the former

ais523

of the program

Dada

having a type system that prevent stack overflow will be very restrictive on the language, no?

ais523

(other than tail recursion, obviously; from a computer scientist's point of view, all loops are recursive)

@Dada to some extent yes, but there's still a lot you can usefully accomplish

Dada

can even still be turing complet?

ais523

no, it can't be

this is the case for all programming languages and computers that exist in practice though

Nathan Merrill

20:50

@ais523 so, in theory, you could prevent stack overflows, however, you could practically get a stack overflow with enough states

ais523

(on esolangs.org we use the phrase "bounded storage machine" for something that would be Turing-complete if it had infinite memory, but isn't because it only has finite memory)

@NathanMerrill in the output of the compiler I wrote, it was possible to enumerate all possible instruction pointer + stack combinations in advance

Nathan Merrill

ah, so the resulting program was hardware specific

ais523

in fact it had the advantage that the stack was distributed over the program, rather than all being in one place, which means your program can run faster and parallelize better because it doesn't have a central bottleneck

I want to "add" four new rows of pixels to the left of an image. Not scale, but just add four pixels of the same color to an image. How would I go about doing that?

ais523

what format is the image in at the moment?

most image editing libraries have a command to resize the canvas without moving the underlying pixels

noɥʇʎPʎzɐɹC

20:53

@ais523 png

ais523

either you resize it larger from the left, or (if that isn't an option) you resize it larger from the right, then translate

noɥʇʎPʎzɐɹC

My image editor edits png directly

@ais523 Not an option

Mac Preview, technically it's PDF and Image viewing software :P

ais523

in several PNG editors I've used, you can just find a resize handle to the left of the image, and drag it further left

noɥʇʎPʎzɐɹC

And I can't find a way to do it in paintbrush (MS Paint for mac)

ais523

oh, I can't help with mac software

noɥʇʎPʎzɐɹC

20:54

I'm looking for a tool

@ais523 Does inkscape have that?

ais523

both MS Paint and Kolourpaint (my Linux equivalent of it) have a resize option in the menus that let you specify a precise number of pixels, also let you drag handles

Inkscape is a vector image editor, it's a poor fit here

mınxomaτ

Inkscape is a vector suite, not a raster editor.

ninja'd

You can use GIMP. But for macOS, there's hardly anything better than Pixelmator (or Affinity Designer, which can handle vector and raster)

Both are paid

ais523

this is a common issue with Mac OS X (all the good software being paid)

Kade

This may be getting too complicated if you only have to do it for one image but I remember when I was messing with video there was an extremely powerful scripting language that can do a lot of stuff (including this)

ais523

actually many application developers target Apple hardware specifically because they have less competition from free programs, so that people are more likely to pay for their paid ones

Kade

20:57

I can't for the life of me remember the name

noɥʇʎPʎzɐɹC

Paintbrush is MS Paint for mac - free and useful for editing individual pixels

ais523

you might be thinking of ImageMagick/GraphicsMagick? it could almost certainly do it

Kade

AviSynth

ais523

but figuring out how is often a pain

Kade

That's the name of it

ais523

20:57

oh, AviSynth is basically the video-specific version of ImageMagick

Kade

I think it may be windows-only though

noɥʇʎPʎzɐɹC

I think I'll just mess around with ImageMagick, oh ninja'd

ais523

I assume it can handle images because it can handle individual video frames, but that isn't its primary use

{} = brackets or braces?

ais523

braces or "curly brackets"

mınxomaτ

brackets

Lynn

What happened to tryj.tk?

ais523

21:10

"brackets" on its own is ambiguous, but normally refers to ( ) in everyday language and [ ] in a programming context

(although it's a general term that also includes { } and arguably even < >, which are called "angle brackets" when used as a pair)

Dada

I think it's brackets because braces are things to help teeth get better

Calvin's Hobbies

I like brackets

DrMcMoylex

@ais523 Nope. Those are parentheses in everyday

Flp.Tkc

I call them all brackets, but specifically "square" [] brackets and "curly" {} brackets

although that's just if I'm saying it informally

@DrMcMoylex I think it's region dependent. Where I live we call () brackets, parentheses is more of US term.

ais523

@DrMcMoylex: nobody uses the word "parentheses" in everyday language, it's purely for people who want to be technically specific about ( ), like programmers and typesetters

DrMcMoylex

21:13

... I do

At least, when I'm talking about them in everyday language, which isn't often, haha

Calvin's Hobbies

More importantly: Why is the shifted (i.e. "uppercase") version of a keyboard key's character on the bottom half? On my keyboard the 0 is above the ).

Calvin's Hobbies

ais523

21:15

the shift key has an upwards-pointing arrow, so most keyboard put the shifted version of the key on the top of the key

quartata

() parenthesis [] braces {} curly parenthesis just to annoy everyone

ais523

this is a bit inconsistent because you'd expect the keyboard to be labelled with lowercase letters in that case (unless you assume that caps lock is on by default; in the very early days of terminals, it would have been, because it took a while for lowercase to become available everywhere)

Calvin's Hobbies

@ais523 not mine, that's what I'm saying

ais523

Calvin's Hobbies

@mınxomaτ Then your + is lonely?

Yodle

21:17

@ais523 The way my keyboard is, the letters are at the top of the keys, similar to the shift characters for the other ones, so it kinda makes sense then. They just omit the lowercase versions of the letters below.

quartata

@ais523 That was just a joke. I usually do parenthesis-square brackets-curly brackets.

DrMcMoylex

So I asked a (very non-technical) friend of mine what they're called, and he said parentheses with no hesitation.

Flp.Tkc

does anyone actually type on layouts like dvorak? Apparently it's faster, but it'd be hell working on computers that aren't yours

DrMcMoylex

Now I'm curious if it is a regional thing

Flp.Tkc

I think it is

I've never heard a proper british person say parenthesis, I picked that up on american-based sites like SE

ais523

21:18

@Flp.Tkc: due to a terrible mixup at work, I spent some time working on an AZERTY keyboard even though I'm not French

DrMcMoylex

So you would call them brackets?

Flp.Tkc

definitely

ais523

it wasn't that hard to get used to, but I mostly set it to a UK layout anyway and just touchtyped

TuxCopter

On my keyboard the shifted is at the up left and the alt-gred is at the bottom right with the normal letter being at the center

@Flp.Tkc Unless I'm transcribing, I can't think faster than I can type anyway

Flp.Tkc

it's like how you use pedmas, we used bidmas - the b is for brackets
