@J_cordz7+Today I did another Hack Club :hack-club: Pull Request! :pullrequest: This time on the Scrappy :scrappy: Repository! :quad_parrot::github: It's an update to the emojiKeyword.js file, I added more emoji keywords, useful to make new automatic posts reactions on Scrapbook! :parrotdad: I'll try to add more on this next days, beside working on other projects! 🌩️ Also today was the start of my last week :tw_spiral_calendar_pad: at High School! :backpack: After this, I will only have my final exams and classes will be over, this is a bit sad :sadge: but thanks to all of the amazing :cooll-dino: memories I have at my school, I look forward for the future, and I know I made good friends, had great teachers and had a great time. :yay:
@ella0Added a streaks page to the Scrapbook site. See the leaderboard at scrapbook.hackclub.com/streaks
I also rode a bike with clip-in pedals for the first time. I fell twice, but it was super fun. Also chased some geese.
@ian0I just set up my firefox default monospace font to comic mono.
@BenjaminSmith7+Tried making Ruz Hashweh from a Palestinian cookbook I found, it is very good
@neel.redkar3i ate some good pizza (this isn’t a picture of the pizza i ate)
@ced0imagine you were making a multiplayer web game
at regular intervals on the server, you want to tick your simulation.setInterval(() => {
your players move forward, ➡️
your enemies decide who to badger next, :threat:
some of your projectiles are just barely dodged, :flug:
and others smash satisfyingly into their targets :bonk:}, 1000 / 60);
at each of these intervals, the server decides which of these occur, and which ... do not.
the difference is quite literally life and death for the denizens of your online realm:
if a player's input makes it to the server just after this update has occurred, they might just not move out of the way of the oncoming missile in time.
after one of these updates when the server has just finished making these vital decisions, it blasts relevant portions of them out to everyone who's connected to your server. (there's no point in updating you about something if it's happening on the other side of the map!)
meanwhile, in the player's web browser, these regular updates from the server are gradually applied, so the server's periodic contemplation is rendered as a seamless sequence of fluid movements...
unless those updates aren't really so regular at all ...
the contract that the server has with the client -- that the server will give the client evenly spaced out updates at regular-enough intervals so that the client can smoothly move between them -- isn't actually the same as the contract that setInterval provides.
all setInterval(update, 1000) means is that there will be ABOUT one thousand milliseconds between each of your updates, usually more. so if the actual interval ends up being 1009ms one frame, the next update won't be about 991ms later so that updates happen at regular one second intervals, it will be more like 1007ms later, so that now you're a total of 16 ms away from the contract you had with the client. this is known as drift.
at worst, this passes on all of the problems of using setInterval for animation onto your game. but what if you're doing something fancier than just moving between the updates you get from the server as you get them? there's always going to be a random delay between what the server sends and what you get, anyway. it might make more sense to push the updates you get from the server onto a stack, and exactly as often as the server updates, pop the next set of positions off of that stack.
... except that if you're popping using one setInterval on the client, and the server is pushing out those simulation ticks using a setInterval of its own ... and each has a different drift ... they're quickly going to fall out of sync. if the server is drifting a lot, your stack might gradually accumulate thousands of positions that you just can't keep up with ... and if the server is drifting less than you are, you might run out of positions to show the player!
suffice it to say, it's super important to have a setInterval that updates without drift. I threw together an implementation of one this morning. I call it a `tick`, since it works well for those simulation ticks I was talking about before. To test it, I went ahead and also made a drift visualizer. Here's a screenshot of it! The grey lines are spaced out at 0.5s intervals, and the first row of blue marks is made by setInterval, while the other row of blue marks are made by my own tick function. as you can see, they stick to the "wall clock time" a lot better than Interval does, even when you leave it running for several minutes!
here's a screenshot! I'll post the source in the thread :)
fun fact: everything that moves is a CSS animation 😂
I didn't want to pollute the JS event loop, although now that I think about it, it might've been better to so that I can see how well my ticker keeps itself together in the presence of some event loop pressure.
@J_cordz7+Second journey update! So I continued travelling and got out of the state! I continued listening to great music and fell asleep 🛌 for a while, and after waking up again, the environment ⛰️ nature 🌵 and weather started changing because I was on a different region, so it got fog 🌫️ and a lot lot more colder! ❄️ After another hours I arrived to the country's capital where I went from the bus station 🚉 where that first part of the journey ended 🚋 and went to the airport where I ate a soup :soup-with-herb: and a hamburger 🍔 and then went to my plane after another few hours. ✈️ Here's some images of the landscape 🌆 there aren't images on the plane right now because there's no internet there, so wait for my last update!
@belle0Hey fwens :partyparrot_wave1:
Hope you're enjoying your weekend!! This morning ☀️, I attended the Feross AMA hosted by @pranav and it was sooo much fun! Feross is insanely cool haha... like he just builds things he's interested in and tries to test the limits of technologies he uses :)) Also, I worked on more maths past papers and created an abomination for the annoying website challenge... I think a piece of my soul died :ratcap:. Hope you have an amazing day :blobcosy:!
@J_cordz7+First trip update! As you already know due to the first update of today, I waked up at 4:00 AM 🕐 and arrived to the bus station 🚉 after having an early breakfast 🍳 at 6:00 AM! Then I aboard the bus as you can see on the first image which is on the dark! Then I continue travelling through the state looking at the mountains and the sunrise while listening to some cool music 🎵 🎧 like Imagine Dragons! It was a very cold 🧊 and cloudy ☁️ morning!
@christina6950Getting into Terminal/command line and wondering about writing my first script. Spent 30 mins reading the Free Code Camp email this morning
@J_cordz7+Today I'll go to a small trip 🗺️ so I won't have time to work on projects! Instead I'll be on the road 🚗 and then on an airplane ✈️ to go back to my first home! I will be reading some interesting books, listening to some cool music 🎧 and maybe I will draw 🖊️ a bit, play some games 🎮 or code 💻 locally depending on my devices batteries! 🔋 I'll try as well to share images, so meanwhile here's two very cool :blob-cool: landscape images 🌆 part of my first Scrapbook post of the day! :tw_tada:
@J_cordz7+Today I added new HTML and CSS files to my personal website Repo on GitHub! :github: I also made a few changes to my README Profile, because I wrote new text that I'll add soon and moved my trophies ⭐ theme from Monokai to Gruvbox. Also I learned about what Prettier indentation is thanks to @caleb! Next, today was my last school day before my break so this next two weeks are free and I'll have time to relax, study more, code and make new things! I will also try to work with my workshops and I'll make a pull request to GitHub Docs because I found a typo on their page! 👀 :pullrequest:
@ella0Scrappy knows :spring-of-making: (#330) (and now also changes the seasonal emoji reaction automatically :wom::spom::som::aom: thanks to #331 - :santasam:)
@matthew0i still need to make a new personal website, but in the meantime i added some of my technical projects to my current site yay
@jessicard7expanded the docs on scrapbook about how to create one, post on it, and all the slash commands available :scrappyparrot: so meta
@jessicard7added instructions to the scrapbook readme on how to run the project locally :scrappy:
@J_cordz7+While @scrappy-U015D6A36AG wakes up and gets repair :scrappy:, I'm also learning about Proxmox! Also I checked out PhotoPrism as an option to self host my photos! I will be sharing more self host tools and apps I find during this next days!
@ced0scrappabotomy(n)making any minor change to scrappy's codebase;a portmanteau of scrappy + lobotomy
@maggie1Since vercel removed its 50 domain limit for pro accounts and also has a new api endpoint for delegating subdomains, I made a bunch of pull requests to try to make vercel managed custom domains work for scrapbook! So now if you run /scrappy-setdomain, you should be able to set a custom domain, even if the domain is managed by vercel :yay:
@suryaansh3Tried a different image upload method today: 0x0.st/ooQu.png but scrappy did not accept. Mostly did the review thing, although will do for some more hours this night but may not remember to take screenshot at that time so did it now. scrappy tags: js, night, review
@HenryBass-U02KEJ8T6D80changed around the code for some of the visuals on my desktop until I got somthing i liked, started work on a gnome extension, and am working on setting up home proxy, and adding multi-channel support to my chat app.
holy shit
also because screenshots of code suck and i need to put an image (fuck you, scrappy)
more shameless desktop pics
@caleb2ooooooo forgot to post this last week: I passed an audition into the NH All-State Festival Orchestra, basically an annual event for the top high-school musicians in New Hampshire! :nh: I'm super excited this year because (barring catastrophe) it'll be in-person again (it was canceled my sophomore year and "virtual" my junior year)
attached is a nonsensical series of numbers to appease scrappy
@Ishan0Today we moved in my parents’ bed, I finally checked my post and found I had already gotten stickers from Hugo days back, me and my sister played in the park with ziplines and I went for a tour of my new school.
Attaching garbage for scrappy to eat (slack is buggy and won’t send the actual images of the stickers and the school)
@Ishan0Got the Tdap vaccine (schools here need me to have it), went to my school again but it was closed, went to the bank with my parents (who opened an account) where we asked the guy if I could have my own bank account but he said he needs special permission from his manager cause im a minor, and in the morning I became part of something exciting:shut: 👀.
Posting a random screenshot cause scrappy is a complain bot.
As one of the Zachs says, there are no surprises in Hack Club.
@fayd0scrappy is bacc it seems, I bought epic react!! :yay:
@sampoder1🚩* Hello there! Scrappy has been working hard at Hack Club for almost a year, 24/7! That’s a lot! So Scrappy has sailed off to a far away ocean and will be down periodically today as we upgrade their internals. Any data inputted into Scrappy in these hours will likely not be saved.
@sampoder1I’ve been hacking on Scrappy (:prisma::postgres: 👀), just testing I haven’t broken them in the mean time
@nimit28010Today I started using Scrap Book!
Would try to add more here :happy_ping_sock:
@matthewvandyke080After 399 days my streak has officially come to an end! This morning I got the painful message from @scrappy that I forgot to post last night. I completely meant to but it slipped my mind for the first time in 399 days, kinda upset I was one day off from 400! I probably won't be posting daily anymore to my scrapbook but I kept the streak going for a while so I think its time for a little break. Thanks to everyone who followed along for 399 days!
@malte0Hello big daddy @scrappy in the sky! Today I wrote an ethics essay and yelled at an amp!
@malte0Hi @scrappy! Today I worked on how the images for the analysis page are rendered, and made it much faster (images are uncached in GIF attached)
@caleb2so I've been a Hack Clubber for a year today! 🎉 thanks so much to everyone who's made this such an amazing experience 💖
here are my first 2 public messages to appease scrappy :rayge:
@ArcadeWise4Just helped solve an issue with scrappy! Thought the best way to celebrate would be a scrappy post.
@ArcadeWise4Scrappy has given out their bitcoin info!
@heyrajan0every day, i have to start searching and searching for things to add to my scrapbook. today.. was one of those days. i accomplished pretty much nothing, so I had to search and search for something to post. Then, I remembered that I finally enabled my Notion Pro account this morning, so I guess that is something I did!?? In the long run, I hope this helps with project planning because that is indeed one thing I lack any ability to do :big-brain-funny: anyways scrappy, here is my daily post!
@matthew0After lots of struggling, Scrappy is finally off of Next.js and is now its own Express app. The code looks mostly the same, but now hopefully it'll stop crashing.
I tested this as much as I could before merging into the real scrappy, but admittedly I didn't test every feature (only a few basic ones, like posting and some commands). So if you run into any issues with scrappy, please let me know so that I can look into it 🙌 :scrappy::scrappyparrot:
