Updates

We got it scraping total channel count so far

Proper list

• Link up stats page to clickhouse
• Fix it not pushing to clickhouse often enough
• Start off with scraping total channel count
• Docker compose stuff

Fun Fact: There is a total of 15,958 channels in Hack Club Slack!

Updates

Basic project setup

Updates

We got a semi working bootstrap
one could say…

Completions

• Lexer/parser
• some x86-64 code generation
• ELF binary writer
• labels & jumps
• Constants like $ amd . for current address
• String and data directives
• Control flow (beq, bne, blt, bge, bltu, bgeu, ble, bgt, bzs, bnz, j, jal, jr, jalr, ret)
• Arithmetic logic
• Comparison
• Memory
• Function calls & returns
• Stack frame management
• Basic Error reporting (its shit)
• Multi-file programs

Why is this going so fast?

I learned from Shiden in flavortown

Updates

• Redid the ISA-spec to be proper and better
• Added AI policy & AGENTS.md. Sym linkend CLAUDE.md -> AGENTS.md
• Added dependabot.yml for gh actions
• Funding.yml, pull request template too
• Added a boostrap-ci.yml workflow
• Made an ASL file for Skyscraper

Init

We made init of repo
And we make a ISA-spec.md file

Updates

• Did a banner & Logo
• Add a pung command, it pings a certain user when you use it
• Added slash commands where the slash cmd msg is deleted instead of kept
• Fixed help cmd deleting slash cmd msg when it should not be

Updates

• Updated docker-compose
• Added pinging bot as a way to use its commands
• Auto reconnect ws after slack api decides to end it
• help cmd responds without threading due to slack api limitations
• Commands when pinging bot always responds in thread, even help cmd
• Added a meow cmd

Updates

• This Devlog took a while 😭

Anyway on to the changes..

• Slack-asm help command
• Ability to respond in threads
• Roadmap updates
• Docker updates
• Minor help message updates
• Just check the commit messages 😭
• Added Slack bot token handling and HTTP POST functionality
• Introduced load_bot_token function to extract the bot token from the environment buffer.
• Implemented slack_send_http_post function for making HTTP POST requests to Slack API with optional authorization.
• Updated slack_fetch_channel_ts to utilize the new bot token for API calls.
• Enhanced slash command handlers to send responses using slack_send_http_post.
• Added support for response URLs in slash command responses.
• Introduced memmem function for searching byte sequences in memory.
• Added debug logging for TLS operations to aid in troubleshooting.
• /slack-asm help now replies in a thread, though its not the correct thread

The screeny below is from after i ram /slack-asm help
What happened is it deleted the /slack-asm help msg and instead replied in my most recent other message

Updates

• Changed a bit of logic so .asm extension always triggers language detection based on file type so it results in Assembly
• Replace inline detection in heartbeat_ingest.rb with fill_misisng_languages call for consistency
• Updates tests

So as the pr explains
I added a merge for .asm files to log as Assembly time instead of the bunch of random things it does instead.

Also implemented a test but did not commit it incase it was not needed

Updates

• We implemented a frick ton of tests

• sha256 hmac tests

• prf kdf tests

• tls record tests

• tls handshake tests

• tls connect tests

• aes cbc tests

• encrypted record tests

• x509 tests

• http tests

• rsa tests

• gcm tests

updates

• WE GOT WORKING SLASH COMMANDS
  (See screenshot below)
• Also fixed an indirect address displacement warning
• Fixed us not replying to the slack api with proper json
• Still not deployed

Next up

• Messages that are visible to everyone
• It replying to certain phrases (maybe)

Updates

• FD might kill me

• We spent 2hrs fixing the first 3 bytes of keystream being wrong for the last block when we were calling the slack api.

• Implemented a ENV parser

• Yet another gitignore update

• Fixed parsing extensions wrong

• Reached 8.2K LOC

Updates/Status Report

Changes for this devlog

• TLS alert Handling
• Updated content length from 32 to 64 bit for >4GB response bodies

Status Report

We have Full HTTPS working end-to-end
This includes but not limited to:

• Full TLS 1.2 incl handshakes
• Full HTTP support
• TLS libraries:
  • SHA-256
  • HMAC-SHA256
  • AES-128- CBC & GCM
  • RSA support
  • ECDHE key exchange
  • They are implemented enough for TLS
• We have Linux syscalls
• We at 10161 lines of asm, 7.6k LOC, 1.2k Comments & 1.3K blanks

What Next?

We integrating this bad boy with slack api

PS: ignore the bad request part in the image below

Summary

Frick me, most of this devlog what trying to fix one single bug.

The hardest part of this devlog was fixing the stupid bugs i had.

2ND PR!

Link: https://github.com/hackclub/stardance/pull/564

Fixes #541

Notes:

Allows Users to Delete Their Own Project. Following the Admin way to do it, it only soft-deletes the projects to hide it from everybody.
