My words to live by...
Another one got caught today, it's all over the papers. "Teenager
Arrested in Computer Crime Scandal", "Hacker Arrested after Bank Tampering"...
Damn kids. They're all alike.
But did you, in your three-piece psychology and 1950's technobrain,
ever take a look behind the eyes of the hacker? Did you ever wonder what
made him tick, what forces shaped him, what may have molded him?
I am a hacker, enter my world...
Mine is a world that begins with school... I'm smarter than most of
the other kids, this crap they teach us bores me...
Damn underachiever. They're all alike.
I'm in junior high or high school. I've listened to teachers explain
for the fifteenth time how to reduce a fraction. I understand it. "No, Ms.
Smith, I didn't show my work. I did it in my head..."
Damn kid. Probably copied it. They're all alike.
I made a discovery today. I found a computer. Wait a second, this is
cool. It does what I want it to. If it makes a mistake, it's because I
screwed it up. Not because it doesn't like me...
Or feels threatened by me...
Or thinks I'm a smart ass...
Or doesn't like teaching and shouldn't be here...
Damn kid. All he does is play games. They're all alike.
And then it happened... a door opened to a world... rushing through
the phone line like heroin through an addict's veins, an electronic pulse is
sent out, a refuge from the day-to-day incompetencies is sought... a board is
found.
"This is it... this is where I belong..."
I know everyone here... even if I've never met them, never talked to
them, may never hear from them again... I know you all...
Damn kid. Tying up the phone line again. They're all alike...
You bet your ass we're all alike... we've been spoon-fed baby food at
school when we hungered for steak... the bits of meat that you did let slip
through were pre-chewed and tasteless. We've been dominated by sadists, or
ignored by the apathetic. The few that had something to teach found us will-
ing pupils, but those few are like drops of water in the desert.
This is our world now... the world of the electron and the switch, the
beauty of the baud. We make use of a service already existing without paying
for what could be dirt-cheap if it wasn't run by profiteering gluttons, and
you call us criminals. We explore... and you call us criminals. We seek
after knowledge... and you call us criminals. We exist without skin color,
without nationality, without religious bias... and you call us criminals.
You build atomic bombs, you wage wars, you murder, cheat, and lie to us
and try to make us believe it's for our own good, yet we're the criminals.
Yes, I am a criminal. My crime is that of curiosity. My crime is
that of judging people by what they say and think, not what they look like.
My crime is that of outsmarting you, something that you will never forgive me
for.
I am a hacker, and this is my manifesto. You may stop this individual,
but you can't stop us all... after all, we're all alike.

My friends netspeed. Must be nice.... attached in the comments is what I’ve got to work with. It’s sad when my mobile hotspot is faster than my fucking wall connection.

So I just spent the last few hours trying to get an intro of given Wikipedia articles into my Telegram bot. It turns out that Wikipedia does have an API! But unfortunately it's born as a retard.
First I looked at https://www.mediawiki.org/wiki/API and almost thought that that was a Wikipedia article about API's. I almost skipped right over it on the search results (and it turns out that I should've). Upon opening and reading that, I found a shitload of endpoints that frankly I didn't give a shit about. Come on Wikipedia, just give me the fucking data to read out.
Ctrl-F in that page and I find a tiny little link to https://mediawiki.org/wiki/... which is basically what I needed. There's an example that.. gets the data in XML form. Because JSON is clearly too much to ask for. Are you fucking braindead Wikipedia? If my application was able to parse XML/HTML/whatevers, that would be called a browser. With all due respect but I'm not gonna embed a fucking web browser in a bot. I'll leave that to the Electron "devs" that prefer raping my RAM instead.
OK so after that I found on third-party documentation (always a good sign when that's more useful, isn't it) that it does support JSON. Retardpedia just doesn't use it by default. In fact in the example query that was a parameter that wasn't even in there. Not including something crucial like that surely is a good way to let people know the feature is there. Massive kudos to you Wikipedia.. but not really. But a parameter that was in there - for fucking CORS - that was in there by default and broke the whole goddamn thing unless I REMOVED it. Yeah because CORS is so useful in a goddamn fucking API.
So I finally get to a functioning JSON response, now all that's left is parsing it. Again, I only care about the content on the page. So I curl the endpoint and trim off the bits I don't need with jq... I was left with this monstrosity.
curl "https://en.wikipedia.org/w/api.php/...=*" | jq -r '.query.pages[0].revisions[0].slots.main.content'
Just how far can you nest your JSON Wikipedia? Are you trying to find the limits of jq or something here?!
And THEN.. as an icing on the cake, the result doesn't quite look like JSON, nor does it really look like XML, but it has elements of both. I had no idea what to make of this, especially before I had a chance to look at the exact structured output of that command above (if you just pipe into jq without arguments it's much less readable).
Then a friend of mine mentioned Wikitext. Turns out that Wikipedia's API is not only retarded, even the goddamn output is. What the fuck is Wikitext even? It's the Apple of wikis apparently. Only Wikipedia uses it.
And apparently I'm not the only one who found Wikipedia's API.. irritating to say the least. See e.g. https://utcc.utoronto.ca/~cks/...
Needless to say, my bot will not be getting Wikipedia integration at this point. I've seen enough. How about you make your API not retarded first Wikipedia? And hopefully this rant saves someone else the time required to wade through this clusterfuck.12 -
So recently I had an argument with gamers on memory required in a graphics card. The guy suggested 8GB model of.. idk I forgot the model of GPU already, some Nvidia crap.
I argued on that, well why does memory size matter so much? I know that it takes bandwidth to generate and store a frame, and I know how much size and bandwidth that is. It's a fairly simple calculation - you take your horizontal and vertical resolution (e.g. 2560x1080 which I'll go with for the rest of the rant) times the amount of subpixels (so red, green and blue) times the amount of bit depth (i.e. the amount of values you can set the subpixel/color brightness to, usually 8 bits i.e. 0-255).
The calculation would thus look like this.
2560*1080*3*8 = the resulting size in bits. You can omit the last 8 to get the size in bytes, but only for an 8-bit display.
The resulting number you get is exactly 8100 KiB or roughly 8MB to store a frame. There is no more to storing a frame than that. Your GPU renders the frame (might need some memory for that but not 1000x the amount of the frame itself, that's ridiculous), stores it into a memory area known as a framebuffer, for the display to eventually actually take it to put it on the screen.
Assuming that the refresh rate for the display is 60Hz, and that you didn't overbuild your graphics card to display a bazillion lost frames for that, you need to display 60 frames a second at 8MB each. Now that is significant. You need 8x60MB/s for that, which is 480MB/s. For higher framerate (that's hopefully coupled with a display capable of driving that) you need higher bandwidth, and for higher resolution and/or higher bit depth, you'd need more memory to fit your frame. But it's not a lot, certainly not 8GB of video memory.
Question time for gamers: suppose you run your fancy game from an iGPU in a laptop or whatever, with 8GB of memory in that system you're resorting to running off the filthy iGPU from. Are you actually using all that shared general-purpose RAM for frames and "there's more to it" juicy game data? Where does the rest of the operating system's memory fit in such a case? Ahhh.. yeah it doesn't. The iGPU magically doesn't use all that 8GB memory you've just told me that the dGPU totally needs.
I compared it to displaying regular frames, yes. After all that's what a game mostly is, a lot of potentially rapidly changing frames. I took the entire bandwidth and size of any unique frame into account, whereas the display of regular system tasks *could* potentially get away with less, since most of the frame is unchanging most of the time. I did not make that assumption. And rapidly changing frames is also why the bitrate on e.g. screen recordings matters so much. Lower bitrate means that you will be compromising quality in rapidly changing scenes. I've been bit by that before. For those cases it's better to have a huge source file recorded at a bitrate that allows for all these rapidly changing frames, then reduce the final size in post-processing.
I've even proven that driving a 2560x1080 display doesn't take oodles of memory because I actually set the timings for such a display in order for a Raspberry Pi to be able to drive it at that resolution. Conveniently the memory split for the overall system and the GPU respectively is also tunable, and the total shared memory is a relatively meager 1GB. I used to set it at 256MB because just like the aforementioned gamers, I thought that a display would require that much memory. After running into issues that were driver-related (seems like the VideoCore driver in Raspbian buster is kinda fuckulated atm, while it works fine in stretch) I ended up tweaking that a bit, to see what ended up working. 64MB memory to drive a 2560x1080 display? You got it! Because a single frame is only 8MB in size, and 64MB of video memory can easily fit that and a few spares just in case.
I must've sucked all that data out of my ass though, I've only seen people build GPU's out of discrete components and went down to the realms of manually setting display timings.
Interesting build log / documentary style video on building a GPU on your own: https://youtube.com/watch/...

Substantive post / question time!
So I'm working on this project that isn't a disaster but very much suffered from a lack of planning (both on my part and others).
This is a feature that involves all sorts of ways to view and manipulate some records and various records and so forth... I mean what isn't that really?
I think everyone tried but we didn't realize how many details there would be and how much we would need to (well I demand we do) share code across pieces and how that would slow us up when we realize feature A needs to do X, Y, Z and ... well obviously that means feature B has to also...
I'm not really upset about this, it's progressing and I'm learning. I'm writing it all now so it's under control, but...
I want to be able to display, visually where we are as far as each component of this project
- Component A
- Description:
- Component A does things you don't want to.
- Has features:
- Can blow up things in a good way.
- Produces flowers and honey on demand
- Missing features:
- Doesn't take out the trash.
And so on for component B, C, D, Z.
Right now I'm just using a plain old document file to write up a status / progress type thing now.
We use Teamwork to manage tasks, but I kinda hate it. It's similar to the above example in being able to bust out lists... but they're not connected in any way. All the details are lost on these bullet items as they're limited to one line when you look at everything ....
It's the classic case of a tool that shows lists ... but doesn't promote or allow for showing any connections between them...
And really the problem with this project is that we built little bits and features here, and little bits there from the outside in and ... really we should have built it from the top down where we had to face a lot of questions earlier.
Anyway does anyone know of anything that has project type management / status / progress stuff that is VISUALLY helpful .. not just a bunch of lists and progress bars?
I know I didn't word this well but I'm open to even wrong answers....2
