At university I had an introductory C course where one assignment was to write a program that searched a 4x4 array of booleans for groups of cells set to true. Groups had to be rectangles, powers of 2 in width and height, and could wrap (i.e. they could go off the right edge and back on the left edge). We had to submit our programs by e-mail and printed form one week later. The prof. marked the paper versions and the TA ran and tested the digital. One slight problem, if you used the university owned printers, they charged for print outs. A few pence per page to cover costs and stop people abusing the rather nice high quality printers the computer faculty had.
I'd always enjoyed programming and whilst C was new to me, using another language wasn't a big problem. As I worked on it I realised the problem wasn't as straightforward as I first thought, but I spent a few hours on it that evening and had a solution I was happy with.
Penny was a student on the course whose approach to academia was memorization. She didn't consume, process, and apply concepts. She just remembered them. Her favourite subject was maths. While the rest of us were struggling to derive some formula, she'd have just committed the process to memory.
Penny was complaining a lot on this programming assignment. She didn't understand why the assignment was so hard for an introductory class. I didn't judge. I know some people find programming hard, but I didn't feel I could help her much without jeopardising my own mark. There's only so much uniqueness in a small program and if she just copied my solution we'd both get penalised for plagiarism. I did mention to her the cases I'd found tricky to get right was when two groups overlapped. If one group completely covered a smaller one you'd only report the bigger one, but if not you'd report both groups.
I heard, through her boyfriend, that that week had involved many long evenings working on this assignment, but she turned up at the next class solution in hand. Obviously stressed, she carried a pile of paper of several hundred pages. She had written a program that consisted of an if-statement for every possible group size and location. About a hundred different possible groups. Each condition written with constant value indices into the array. To cope with the overlapping groups problem, checks for smaller groups also checked that no larger group also covered this area. No loops. No search algorithm. Just a linear program of if-statements.
Apparently debugging this has been a nightmare. Cut and paste errors everywhere, but when I'd told her about overlapping groups aspect it had blown her mind. There always seemed to be a combination she hadn't accounted for. Multiple times she thought she was done, only to find a corner case she'd missed. And just to kick her when she was down, she'd paid for multiple printouts, each one costing about £10 only to find a problem afterwards.
This consistent A grade student who sailed through everything by relying on her memory had been broken by being asked to create an algorithm rather than remember one. She got credit for submitting a solution that compiled and solved some cases, but I doubt the professor got past the first page of that huge printout.
Penny had worked really hard for that D.
Honestly back when I was a kid this is how I thought games were made, every possible image of a game was already saved and according to your input it just loaded the next image.
I stopped thinking that with 3d games
I thought that they were managing that stuff on a per-pixel basis, no engine, assets, or other abstractions, just raw-dogging pixel colors.
And before I even played video games at all I was watching somebody play some assassin's creed game I think and I thought the player had to control every single limb qwop-style.
In the first few Assassin's Creed games, they did use the idea of a Puppeteer system for the control scheme, although it wasn't physics-based or anywhere near as hard as QWOP. Each of the controllers face buttons performed actions associated with each limb, and the right trigger would swap between low profile actions and high profile actions.
In the top right of the screen, there was always a UI element showing what the buttons did at that moment in that context, which might've been why you thought it was a QWOP style system. It's not exactly what you were thinking of at the time, but you were closer than you realise.
Apparently ai is learning to do that first thing you said about pure pixel management. It's crazy that it works at all
I remember having a thought one day as a young kid while interacting with a DVD main menu (the kind that had clips from the movie playing in the background, and would play a specific clip depending on what menu you went in to).
"This is basically how video games work, there's a bunch of options you can choose from and depending on what you do it shows you something. Videogames are just DVD menus with way more options."
I grew up to not be a programmer.
Those shitty old tiger hand holds kind of worked like that.
Its not terribly far off from pre rendered or FMV games like Myst are doing it.
This is what I believed. And I tried to trick the game by doing movements and inputs no one could have planed. Never outdid that planning somehow. They were on to me!
I remember speculating as a (small) kid that the AI soldiers in Battlefront II's local multiplayer might be real people employed by the developer. Not the brightest child was I.
I remember as a kid seeing my older brother talk to people on a mic and thought he was talking to the characters in the game
I grew up mostly with the PS2 and above and I thought the same thing 😅. I did think there had to be a better way though
Dragon's Lair was a hugely popular arcade game that worked that way.
Programming chess as a single lookup table is wild
Right?
pretty sure there are more possible chess positions than atoms in the earth (universe?), so even if every atom of our planet were converted to transistors there'd be no way to fully represent all possibilities.
This was a fun one to look up. https://en.wikipedia.org/wiki/Shannon_number
It looks like the number of valid chess positions is in the neighborhood of 10^40 to 10^44, and the number of atoms in the Earth is around 10^50. Yeah the latter is bigger, but the former is still absolutely huge.
Let's assume we have a magically amazing diamond-based solid state storage system that can represent the state of a chess square by storing it in a single carbon atom. The entire board is stored in a lattice of just 64 atoms. To estimate, let's say the total number of carbon atoms to store everything is 10^42.
Using Avogadro's number, we know that 6.022x10^23 atoms of carbon will weigh about 12 grams. For round numbers again, let's say it's just 10^24 atoms gives you 10 grams.
That gives 10^42 / 10^24 = 10^18 quantities of 10 grams. So 10^19 grams or 10^16 kg. That is like the mass of 100 Mount Everests just in the storage medium that can store multiple bits per atom! That SSD would be the size of a
smalllarge moon!
Its written vibe.
This is actually what made me start my programming journey. Made small games using PowerPoint until I was starting to make an level editor on a 12x12 grid. My father thankfully stopped me pretty early on and showed me Game Maker 7. Not sure for how long i would have continued.
Are you me lol? I did exactly the same, and at some point I started computing how many slides I had to make to make anything larger and I pivoted. My dad didn't know this stuff but I also ended up at gamemaker
PowerPoint is actually turning complete so... https://youtu.be/uNjxe8ShM-8
hey, there is an inherent fun in maing games/programs using things that were never meant to.
once i did a CPU/RAM emulator using excel, so you could see every bit.
it was fun to make loops, and programs
I suddenly feel in good company. I got my start doing crazy things with PowerPoint and Excel because it was what I knew.
I coded basic games in PowerPoint using animations plus VBA. Not good.
This is very inefficient, they should be using a switch case.
For efficiency you should you GOTO, so you can join trees that end up in same position.
Like those create your own adventures books.
now implement castling in that
AI has probably finished this game by now.
And still lost.
As a middle schooler I used Power Point to make FMV games for my friends and classmates, and it was basically this. Just, like, SO MANY slides
This is where you'd normally go "there must be a better way..."
Not some people.
This is a great advertisment for what real developers do. You shouldn't just crank out the first idea that works. You should be doing something that is smarter and sensible.
Are they trying to code every possible chess position??
The implication is that the person in the meme is
Laughable for chess, but essentially how Steve Mould played tic tac toe using synthesized DNA.
Well this is how programing works so if you don't like it...
They are doing it dumb. You can text output chess but you just need to keep track of where the pieces are in code, then when you are ready to output, place the characters. Saves so much time. /s
not to get epistemological,
but I hate that technically there's only a limited number of moves in chess, and therefore the best move is there, maybe there's a strategic where white will always win, but we'll never know because the number of variations likely is larger than atoms in the universe.
On the lower end of estimates, the number of unique chess board configurations is 10^120, often referred to as the Shannon number. The universe doesn't stand a chance.
That’s cool. I think this is why I never liked chess.
maybe a distant future technology could compute that, Clarktech style
In modern chess, engines have gotten good enough that we generally do know the top moves and humans can't beat them. We can even numerically assess someone's chess play with a computer, which we call "accuracy". Obviously they can always be improved further, and there are a handful of situations where they might misevaluate, but it's still pretty incredible.
Engines have only made chess more exciting as they have shattered a lot of old theory and helped people find a lot of new and innovative ideas. They are an incredible aid in analysis and tournament prep.
if that is python then makes sense
I'm familiar with issues like this. Lots of copy/pasting with little edits here and there all the way down.
