Trying to see how far I can go with AI Slop fork. A few KLOC of project seems to work well.

I'm creating an autochess-like game in Bevy. Itโ€™s Rust, and itโ€™s going well because itโ€™s easier to write than I imagined.

There is room for improvement on hono/node-server.
It seems that delaying the generation of request body can improve benchmark results on POST. I guess.

I'm reimplementing a URL parser in Rust to solve some issues. Of course, I'm just looking at the Claude Code.

I'm trying to reduce the binary size by using smol instead of Tokio, but it's too much work, so I'm about to give up.

My Fastly Compute-hosted website has recently started throwing mysterious internal server errors.

It's just a static website, but the error doesn't occur locally, so I'm planning to move to another cloud service.

Does anyone know of a node module-free documentation generation tool with Deno?

Must be distributed via JSR or npm.

I recently discovered that Deno publishes a lot of useful Rust libraries, and sui in particular has been useful to me.

I'm grateful to Fastly for providing such fast service, just as their name suggests.

Managing a monorepo with Deno is a less pleasant experience than pnpm, but better than npm.

Web analytics on Cloudflare need to encode URL. missing

I want to use Astro x Qwik on Deno together, but I am frustrated that we cannot use them due to bugs.

As there was no other way, I decided to give up on Qwik.

Thank you for asking.
At the time of the post, I was having issues with the following issue, but it has now been fixed and I am able to use Wrangler without any issues :)

I'm slowly getting free from package.json and Bun.

I tried "deno npm:npm publish" but unfortunately it didn't work.

I recommend you stop using -A in Deno and start using -SRE.
This is the first step towards focusing on security.

I don't know if my voice was heard, but Wrangler seems to work with Deno now.

I'm about to be released from Bun.๐Ÿชฝ

Some npm libraries are bundled to remove unnecessary deps, but this has the disadvantage that users will not know if they are using libraries that contain malware.

If contaminated chalk was bundled together, it would be difficult to detect with the current system except of code scans.

npm makes package publishers' email address public, which seems like a bad practice as it increases the likelihood of phishing emails being sent.

Yep, I've been pwned. 2FA reset email, looked very legitimate.

Only NPM affected. I've sent an email off to @npmjs.bsky.social to see if I can get access again.

Sorry everyone, I should have paid more attention. Not like me; have had a stressful week. Will work to get this cleaned up.
