Forgive me for asking a simple question, I only just started learning programming two weeks ago.

So in this recursive function, the compiler isn't even compiling the code below the recursive step, i.e. the if (min < A[n - 1]) stuff, until it reaches the base case correct?

int findMaxRec(int A[], int n)
{
int min;

if (n == 1)
{
return A[0];
}
else
{
min = findMaxRec(A, n - 1);//recursive step

if (min < A[n - 1])
{

return min;
}
else

return A[n - 1];

}

}

and yes if you imagine expanding it out in your head it will keep recurring at min = findMaxRec until n == 1 (which will never be the case if N <= 0, e.g. if you call findMaxRec(something, 0) it will run forever)

10x engineers are people who spend a lot of time on their one project. Their environment allows them to work this way. This could be achieved by just working 8 hours a day very diligently or completely destroying a work life balance. Spending maybe 60 hours a week on work.
Split their attention sufficiently and you'll ruin that. That's what this manager sees. He could probably improve general performance by segmenting people more and leaving them alone. Assuming they're not just slacking as soon as they could get away with it.

How do I get started writing the graphics output of a terminal emulator or text write program?

I want to support italic, bold, strikethrough etc., so having bitmap fonts is out of the question, and that means i need some sort of font rasterization shit right?
But how are these rasterized fonts sent to the gpu? Is it just software rendering to a framebuffer thats sent as one big texture?

Leo Nguyen

I believe so, of the two font libs I know, fairly certain stb_truetype works that way, and I think that's how freetype works
As I understand it, fonts are a metric bitch and a half, so I'd use one of those two, definitely wouldn't try rolling your own font library.

Mason Sanchez

I feel a bit bad asking here because I don't want to turn /dpt/ into another homework/help place and I've already posted a few questions this week here.

But anyway, I'm basically struggling with map/reduce in Clojure. I have some code which simplifies my actual program:

    (def X [ 1 2 3 4 ])
(def Y [ 5 6 6 7 ])

(defn foo [a b c] (+ (* a b) c))

(def answer 0)

(loop [i 0]
(when (< i (count X))
(let [x (nth X i)
y (nth Y i)]
(def answer (foo x y answer))
(recur (inc i)))))

answer ; should be 63

How do I write this without the loop using a lambda? Everything I try doesn't actually do what this loop does, which is reassign the value of `answer` and use that in the next iteration.

I don't know how fold works in clojure, but in guile you can do it like this:

[email protected](guile-user)> (define (foo a b c) (+ (* a b) c))
[email protected](guile-user)> (fold foo 0 '(1 2 3 4) '(5 6 6 7))
$1 = 63

I had a technical interview where one of the questions was how I would write some data associated with a URL to its own file on a filesystem without collisions. I also couldn't modify the URL to use as the filename because it may have invalid special characters and I had to assume that I didn't know what they all were. I might not have interpreted this constraint correctly but I think that's what was said.

My answer was to use a UUID but I was told something along the lines of there possibly being a collision (a UUID doesn't have enough bits to be unique for every URL). It was a good enough answer but not the best one apparently.

What would have been the best answer to this?

Alexander Flores

I looked into it, but thats just the particulars of rendering a single character. Unless I missed something, it didnt look like the gpu did the dynamic rescaling?

So for SDFs processed fonts you would supply an alpha only channel image in the same resolution as the original bitmapped font, then adding filtering you could render it at a larger scale using the gpu?

Maybe they're just asking for base64url or something. But I would consider the question a bit deceptive if that's the case. And very pointless. You'd absolutely Google that normally if you didn't know. It's not a good way to judge someone.
I had to assume I don't know all the invalid characters
To me sounds like you actually just don't know. The point being you can't hardcode for them. I don't know what the point of that would be. I can't think of a way that'd help you. Any substitution would just collide with the substitution as input.

just drop the dumb var keyword, also retarded type theory one should have type inference (if it really is retarded type theory wankery)
actually even the value 1 should be optional, if it's a good type theory the compiler should be able to deduce the value from the rest of the program.

for example a webpage that shows a table and fetches values from database but depending on count of values it changes table row/column and stuff.
generally how do dynamic websites work/created, is database the only thing that separates static and dynamic sites and maybe run server side programs?

the fuck are you on about? dynamic websites are those that may change on reload unlike static pages that remain the same all the time. Another lesser requirement is responding to user triggered events like clicking but that is also part of the ```responsive``` meme.
Websites obviously use JS to modify the DOM on client-side.
For server-side rendering like Razor pages, an html page is generated from a razor page per request and there should be a mini client.js that sends user events and data to the server and gets a response containing the DOM changes.

Daily offer to prove that C++ is actually no really guys I'm serious capable of performing outstanding memory allocation optimisations:

Then why don't you go ahead and run some C++ program with an overloaded malloc implementation that counts how many 64-Bytes-or-less allocations have been performed? And with a corresponding free overload you can see how long they survived. I also don't care about your synthetic benchmarks for a simple program, all right? I want real-world applications.

, and that's why it's better than C.

inb4 the compiler cannot apply its optimisations
Most real-world applications link their shit dynamically. Dynamic linking means you can inject symbols via LD_PRELOAD on Linux (no idea about the interface on Windows however). Since the compiler has NOTHING to do with symbol resolving that should give you a proper idea of how much a C++ compiler is actually capable of optimisation.

inb4 I'm too dumb to do that; gimme code/instructions!
Take the following code and put it into libcm.c:

how are you determining that it runs five times?
it may be that getchar() also gets newlines when you press enter, so it looks like it only asks you five times. you could change the default case to print a warning for unrecognized characters or something.

I'm trying to thread together a monitoring system with the virtual machine infrastructure with a script so I can automatically do things like query if a vm got shutdown and the last user who touched it. Or boot every VM that was detected as shutdown in the last 15 minutes. Generally my goal is to use simple verbose maintainable scripts to create tools to automate infrastructure monitoring and perform autoremediation.

I've never been a programmer persay yet I find myself reinventing myself into a devops guy and I'm now learning my 4th language. I go to work and I see sysadmins literally ignoring vendor provided best practices that document how to do a specific task with a script and instead come up with pages of step by step directions in a word document. If you can write directions you can write a script you just need to learn the language and syntax. Yet people just don't. I'm starting to realize the opportunity in this phenomenon.

memory allocation optimizations C++ has but not C

I mean I used the word "simple" in my first post.

The idea also gets more complicated due to the quality of the data I'm working with. Basically how this company I'm working for worked was, they would make a VM, email another team the info, and they would punch in info into the monitoring system. This has led to a LOT of human errors and inconsistencies between the two databases. So if I search for something on the 2nd database based on an entry in the 1st database I might not find anything just because somebody fucked up.

I can make what I described kind of work... but I'm trying to figure out how to make the script robust enough to not get fucked up by bad data in either database. I'm finding this tricky...

I have been using Haskell for awhile now, and this is what I have found wrong with the language:
horrid macro system
modules are deficient compared to the module system of OCaml or the package system of Common Lisp
partial functions pervade the language
broken records (ugly hacks are needed to get around their deficiencies, leading to overengineered libraries like lens)
most libraries are in alpha and look like a college student's summer project
library authors tend to pepper their libraries with ugly, meaningless, custom operators, contributing to the overall ugliness of the ecosystem
String as [Char]
easily subverted type system with unsafe functions
laziness makes it a chore even for experienced programmers to reason about algorithmic complexity
in 30 years of existence, Haskell has yet to become a proven asset in industry

Ryder Adams

I'm thinking of something I heard. It's not the freshest memory. But I believe in c++11 the standard started allowing new and delete to be elided. So you'd have a conforming compiler even if you didn't new/delete every time you saw those in code. You'd still have to construct/destruct obviously. But no allocation. I don't know if malloc and free got that same treatment. If they didn't then malloc will always alloc and free will always free. Even when it's unnecessary (it'd be smarter to put things in registers or on the stack or whatever).
It's obviously not the kind of comparison user is asking for even if that's the case. It's not really efficient allocation. It's just the standard being biased.
But you should look that up. As I said I don't remember this well. And the malloc/free situation is speculation. It wouldn't surprise me that much.

broken records (ugly hacks are needed to get around their deficiencies, leading to overengineered libraries like lens)
completely agree, except that lens is actually something good, sure the initial motivation was records, but it is so much more today.
String as [Char]
I used to agree with this, but then I realized no matter what representation would be chosen in the standard library, there will always be unhappy people about it. It's not like every library out there used String for everything either.
easily subverted type system with unsafe functions

in the first place fields aren't overloaded so you've got to use namespace qualifiers or avoid using the same names
in the second place nested record updates suck. obj { x = (x obj) { y = (y obj) { z = newZ } } } for obj.x.y.z = newZ
overloadedrecordfields will remedy some of this but still, use lens instead. (it has some passing relevance for naming fields which is useful for generic code)

This is a totally retarded idea that has somehow become popular.

It is by no means easy to mix strictness and laziness, and laziness benefits from being pervasive.

I'd just like to interject for a moment. What you're referring to as Linux,
is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux.
Linux is not an operating system unto itself, but rather another free component
of a fully functioning GNU system made useful by the GNU corelibs, shell
utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day,
without realizing it. Through a peculiar turn of events, the version of GNU
which is widely used today is often called "Linux", and many of its users are
not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a
part of the system they use. Linux is the kernel: the program in the system
that allocates the machine's resources to the other programs that you run.
The kernel is an essential part of an operating system, but useless by itself;
it can only function in the context of a complete operating system. Linux is
normally used in combination with the GNU operating system: the whole system
is basically GNU with Linux added, or GNU/Linux. All the so-called "Linux"
distributions are really distributions of GNU/Linux.

This is insane. Do you think bounds checking should be off by default because of performance reasons?
Give people an unsafe option if they really need it, but there's no reason to have that shit be the default.
Frankly, if you're in a problem domain where those kinds of microoptimizations aren't premature, you're probably using the wrong language.
Making things lazy in a strict by default has a higher cost.
What? I don't see how, unless the language doesn't support laziness.
And research on a lazy-by-default language was definitely good, but that doesn't change that it's a poor fit for a language if you want to use it in the industry.
That kind of approach might be okay if you're doing prototyping, but beyond that it really isn't a good idea. A program that doesn't do correct error handling just isn't acceptable.

it isn't really unpredictable most of the time though, it's pretty much just when you're analysing the complexity of an algorithm. and most of this is only "unpredictable" because people are taught strict evaluation and techniques relevant to it.

in fact you see people complaining about something being unexpectedly slow or fast in strict languages all the time, because performance itself is difficult to predict except in small sections of code, not because strictness or laziness is making it worse

I've been working in security and other non-programming related fields for awhile now. I still write the periodic script here and there but I've really let my programming ability slide off, thinking about moving to a slightly more programming heavy role for a bit.
Any good websites or exercises to get back in the habit? Mainly a C programmer but more just getting back in the mindset rather than being a library whore.

Has anyone been in contact with KNX?

I want to do some interfaces (e.g. a QT interface) to visualize a few buttons which send tcp commands into a KNX network to an actor.

How do I get started?! Do I need a KNX/IP router or gateway? Is it even possible to do what I want? Is there something easy that already exists to do what I want?

Unironically, California. Everything else there sucks, but you'll get paid 3 times as much, cost of living is higher but the pay increase is still more. Plus you'll be saving more so once you're done with that shitty state you'll move away with a fuckton of extra cash.

The issue isn't the time complexity of algorithms, it's that you don't have any (easy) guarantee as to when it will be evaluated. Even a seemingly easy operation can have large latency because it causes more complex operations to be evaluated, that had been building up until now.

When latency is a concern you can sequence evaluation order (which you would have done in a strict language anyway)

sequence evaluation order
I'm not exactly sure what you're trying to, could you elaborate a bit?

Cooper Robinson
Cooper Robinson

yes, turns out there are lots of applications where you have a very good knowledge of your domain.
bounds checking
if that's the only reason you care about total functions, well, I'm sorry I just couldn't care less about your opinion. It's not like we have a gorillion cheaper ways to ensure these don't go wrong.

I've never heard of that referred to as "sequence evaluation order", but alright.
And yeah, that's what I do, but if I already have to litter my code with bangs just to get strict evaluation back, that kind of makes lazy evaluation redundant.

You completely missed the point of my post instead responding to claims I never made, but whatever.

Ayden Scott

Well the point is it only matters at certain points, e.g. latency isn't always a concern. It might be one extra thing to think about but then so are side effects and unnecessary complexity from strict evaluation.

Henry Roberts
Henry Roberts

your point is literally "not bound checking is really bad, there's no excuse for not doing it, therefore we need to forbid partial functions because it's the only way"

Lincoln Collins
Lincoln Collins

no, it's that it has no point in being the default. I've even explicitly said that there should be an unsafe option to circumvent that if you need it, just like how it is with bounds checking.
But whatever, you obviously have no interest in actually engaging with what I'm saying
