If you make a religion that gives me a religious exemption on having to use proprietary software, I'm all for it.
Though, it should also include that technology belongs in the hand of people that devote their life to it, and not some "end user". A Machine Priesthood, if you will. Gets rid of a lot of problems, like people moaning about CLI software.

>>2420
Most innovation is driven by developers wanting to cater to end users. The entire purpose of computers(and technology in general) is to make people's lives easier. /g/tards only care about intellectual masturbation and elitism, so they miss the point. They're actually segregationist heretics.

Well, it's correct.

If a one-planet species like us with all our problems can make a whole new universe...what makes you think we're not made by someone else?

>>2424
That's not a universe. It's just a video game about a big box of balls, bouncing against or sticking to each other.

So it's been a long time since I programed anything, and I decided to try and make a new project on C. For the first part of the project I have to parse and modify a .ppm image. I always get a Segmentation Fault error when trying to do this. I really don't understand what I'm supposed to do. I mean, the file is binary correct? But I have to open it as a text file, and read the pixels. Then parse the whole thing and proceed to the other parts of the project. Can someone tell me how to actually read and parse a ppm file on C? I read some guides but didn't understand a thing.

>>2425
Look at the first section in https://inst.eecs.berkeley.edu/~cs61c/fa20/projects/proj1/
that explains how to read ppm files. Note that I'm not sure if the ppm files you are referring to are ascii encoded or binary encoded. If it's ascii encoded you can open them up as text and see the raw rgb values, but if it's binary encoded you have to read it in binary mode.

For the binary encoded ppm you'll first want to familiarize yourself with the file format layout, so read https://en.wikipedia.org/wiki/Netpbm#PPM_example then open up a hex editor and try to identify the pieces of the image. Then you can read the binary data into a struct, and tada you've parsed it. Do same in reverse to write out the ppm file.

>Then you can read the binary data into a struct
Beware of field padding and compiler antics - assert() and offsetof() are your friends

>>2427
Good point, there are probably compiler flags to avoid the padding but probably better and safer to avoid reading into the struct directly and instead read the data to a temp buffer, verify that it's well-formed, and then populate the struct.

Do you think it's possible to replicate live board features like those here: https://doushio.com/moe/
without using javascript?

>>2377
Great question. Off the top of my head, here are some possibly mechanisms I can think of for implement real-time updates (which is basically the core issue at hand) without javascript

* Polling, with periodic refresh client-side (perhaps with some judicious use of iframes)
* Hold the connection open and keep streaming content in parts. This can be accomplished various ways: use http chunked encoding (Content-Type: chunked) and basically keep appending content to the page (works well for imageboards), use mjpeg (downside is it's an image), "Content-Type: multipart/x-mixed-replace" (which I've never seen used before so I don't know much about)

>>2378
Interesting. Thanks.

Which cheap VPN should I get?

I've been using LTSC. It's far from perfect, but it works.

Hey that's pretty good!

I'll be updating to Windows 10 soon so thanks OP.

Off-topic, but I don't want to make a new thread.
On windows, you can't tag gif and png files by default. This program fixes that by adding metadata to whatever file types you want(which are supported I guess).

I use Emacs, though admittedly I don't know how to use it too well and mainly use it for org-mode. I do a lot more writing than programming these days anyway.

Any experience with cudatext.github.io ?

I use a highly modified version of neovim-qt. I heavily use the remote attachment feature. I've been doing this for the past 3 years now.

I don't want to talk about vim versus emacs. Most emacs users call vim vi, and don't know the difference or why people use modern neovim.

>>2417
Why did you have to highly modify it?

Would this possibly be a black hole?

if the force is being constructed as a vector the negative sign simply indicates its direction.
the direction being down toward the earth.

>>6
But this isn't force, but potential energy.

As distance between the two planets increases, the potential energy should increase. But the equation dictates that the potential energy will simply approach zero from the negative side. Whys that?

Because it is supposed to be negative.

>This potential energy is more strongly negative than the total potential energy of the system of bodies as such since it also includes the negative gravitational binding energy of each body. The potential energy of the system of bodies as such is the negative of the energy needed to separate the bodies from each other to infinity, while the gravitational binding energy is the energy needed to separate all particles from each other to infinity.

Quanta magazine is the gold standard of understandable reporting in physics/math. Here's their explanation of time crystals

>>2311
I think about this a lot. The half-baked rationalization I am most satisfied with for the moment is that mathematics is so successful at describing the world since it is an enormous repository of arguments; while it may not be the case that every mathematical argument is relevant to real-world phenomena, we are forced to turn to mathematics to find means of concretely describing and articulating what we observe about physical reality. Now that I write it out, though, this revelation seems pretty vacuous.

In any case, yes, it is very interesting that a handful of axioms consistent with how we understand the world could bear so much fruit.

>>2313
"The Unreasonable Effectiveness of Mathematics in the Natural Sciences" seems relevant

No. The theories of mathematicians don't bother me at all.

My dad has that chair. It leans back too much for my taste. I like sitting closer to the edge of my seat, so that sloping feeling annoys me.

(According to reverse image search that's Staples Hyken).
>>2216
You can actually get the higher-end ones for quite cheap used. For instance, you can get Aerons for $250-$350 if you hunt around a bit. And considering that they last 20 years or so and are designed to be repairable it doesn't seem too outrageous. But I don't know if the Aerons are actually as comfortable as people say they are or they're just overhyped placebos.
>>2218
There's probably a way to adjust recline tension

>>2220
Yes, it's Staples Hyken. Sorry for not specifying that.
And yes, you can adjust the recline angle as well as "disable" it completely to allow for it to be similar to a rocking chair.

I was able to test a bunch of chairs in my quest to buy a comfortable one. Here are some quick thoughts, in case it might help anyone else:

* Steelcase Leap V2: A bit overrated in my opinion, I felt "boxed in" by the seat (especially the way the sides sort of curve slightly inwards like a bucket racing seat). It just felt overengineered and heavy, but a lot of people seem to like these so your mileage may vary.

* Think V1: A lot lighter than the v2, and an interesting hybrid between mesh and foam seat/back where they suspend a thin piece of foam on a bunch of metal wires that can flex to mold to your body. But in practice the seat felt pretty uncomfortable, there was almost no lumbar support 9even with their adjustable plastic contraption), and there was no way to set recline tension. I feel like there's a weight threshold to get the metal wires to actually bend, and I guess I was below that cutoff (I guesstimate you need to be > 140 ish)

* Haworth Zody: Currently trying this, I like the mesh back and its lightweight feel. It doesn't have any fancy gizmos like the other two steelcase chairs, it's just a solidly designed chair with all the things you would expect.

Note that the one chair I didn't have the chance to try was the much-hyped Aeron, although I think the hard plastic edges of the mesh seat would have been an instant dealbreaker.

If you're shopping for chairs, it would behoove you to try to find a ushed/refurbished furniture dealer nearby. Depending on your location (rural or urban) this might be easier said than done, but you can usually get chairs from liquidation places or office closing sales for a fraction of their original cost. This guy's [1] reviews of various chairs were also very helpful in identifying things to look for.

I haven't noticed that issue. TC works fine for me along with other "not secure" sites.

>>2380
>>2381
Also, check your network settings to see if you're in "HTTPS-Only Mode".

>>2382
The settings clearly indicate that it's not set to browse in HTTPS only mode. This is what it looks like to browse TC to me. Also if I click a link within the page and get sent to another board it looks normal but when I click another link to another board it gets white again. I need to enter a board while in "white mode" and the click the reply button, or else I will reply like this.

>>2383
I figured it out. The settings was everything set to not enable https, but upon typing a non-https website it would force it anyway, and if it could not be forced a padlock with a "!" would appear. Upon clicking on the "!" padlock it said that firefox was worried about "the user protection" and chose to block certain contents form being displayed. I had to click a button that said "not block features".

If you're on a hidpi screen antialiasing is unnecessary anyway. osx disabled it a few versions back

It also looks slightly better on a CRT, if you're running one for some reason.

>>2296
>osx disabled it a few versions back
Didn't they disable only subpixel AA (keeping grayscale by default)?

>>2373
>keeping grayscale
yeah you're right, my bad. When I played around with subpixel vs grayscale only, the only noticeable difference on the hidpi screen was that with grayscale-only aa, fonts were a bit thinner.

>what's a more bullshit-free way of installing software on a computer?
Software should be distributed as self-contained, compressed files. The number of required middle men should be kept to a minimum. There should not be some group of people who decides what software people have convenient access to. Receiving software should either be a direct exchange from developer to user, or random redistributor to user.

Files fit this mold perfectly. It's piss easy to store, copy, move and share(redistribute) files. It's a virtually universal format. Packages don't meet any of these requirements. They have a learning curve, and they rely both on a specific package manager, and specific version of that package manager. You can't just make a repository and leave it alone forever with no updates, people wont be able to use it. The idea of software sharing all of their dependencies, is also nightmarish and awful.

I like my clickly-click wizards. A lot.

>>2367
I'll concede that .appimages are pretty good. As a once-off thing, they're freer of bullshit than a package manager. Disk space and fast internet speeds are cheap enough that redundantly bundling dependencies within programs is not much of a downside. But if I used them for every program, I think I would get tired of the bullshit quicker than with my current, largely package managed setup.

>>2368
I don't see my computer as a "set-up". There's a few utilities I use way more than others, but I don't usually update those unless I have to and they're few in number. Every other piece of software I use, the majority, is temporary. Some I only use one time because the need for it happened to arise.

Until I get around to uninstalling things to regain disk space, my computer is like a hodgepodge graveyard. I don't worry about "work-flow", or a meticulous configuration or anything like that, I do things as they come and install things as I need them. It doesn't make sense for me to become really familiar with some boxed in environment that may or may not(statistically far more likely) have what I need at that moment.

I'd rather know I can easily get virtually anything I happen to need with minimal chance of issue or having to look things up to fix roadblock after roadblock, and that once I have it, it'll always work.

>>2366
>no dragging and dropping an application to mount it or whatever it is you have to do on a mac
On OSX an application is a completely self-contained (statically linked) bundle, which is basically just folder containg the mach-o executable and resources (icons, metadata, etc.). This approach is the cleanest and best I've seen, basically everything that appimage/flatpak should have been. "Dragging and dropping" is basically just the convention of moving this bundle to the "/Applications" folder, which is done only as a convention; in actuality you can just run the application from anywhere, and even just invoke the mach-o binary inside the bundle directly from the command line. Similarly, the "mounting" you mention is more an artifact about the disk-image used to ship the bundle (think akin to iso image format). This too is unnecessary, since as a bundle is just a folder you can just zip up the thing and send that instead; and indeed, this is commonly done. So in short, on OSX you don't need to "install" anything at all, applications are almost always distributed as self-cotained bundles.

>what's a more bullshit-free way of installing software on a computer?
Package managers are indeed very convenient for certain types of software, but the act of actually getting your package into the repo is so tedious that small developers basically don't bother with it. This is a major reason why Homebrew actually took off on OSX compared to things like macports, beacuse they focused on making it trivial to add new packages.

> largely package managed setup.
I've had more issues with packages breaking because upstream decided to bump some package which then affected some random obscure downstream abandonware. Or being unable to install said abandonware package because it depends on a version of OpenSSL from 2005.
