Most languages have 'opinionated best practices' that are quite bad (according to all others).24 Nov 2025 03:08 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3m6dtwfi2ac2khttps://bsky.app/profile/costinm.bsky.social/post/3lh2emlbink2fFound this simple, clean wrapper for running gVisor contained shell/python, seems useful in many other scenarios besides LLMs. Forgot how much simpler it is to just share (part of) the rootfs and still isolate the app instead of building custom linux distros for each app. https://github.com/EtiennePerot/safe-code-execution31 Jan 2025 16:00 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lh2emlbink2fhttps://bsky.app/profile/costinm.bsky.social/post/3lgiqv6zmhk27I finally realized YAML is not a bad serialization format, but a markup language, like markdown or html - which also maps to a tree of lists/structs. Still as bad for serialization as xml. And json/proto.Struct are intended for serialization - not human reading/writing.24 Jan 2025 15:52 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lgiqv6zmhk27https://bsky.app/profile/costinm.bsky.social/post/3lg4zenasa227Realizing that 'social media' is the fancy name for the old email 'spam'. We had the content - just lacked the algorithms to promote the most engaging or outrageous spams, and the old mail clients made the mistake of filtering it out / hiding it instead of promoting it on top of the Inbox.19 Jan 2025 23:52 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lg4zenasa227https://bsky.app/profile/costinm.bsky.social/post/3lecidkouwc2aPeople tend to focus on the bots spreading things they disagree with - but the ones you agree with are the threat, twisting things you agree/like/want, to achieve the goal of whoever is paying the agents. The ones you disagree with: targeting others, or to make you more receptive.27 Dec 2024 17:12 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lecidkouwc2ahttps://bsky.app/profile/costinm.bsky.social/post/3ldzhgzupnc2cWould be nice if comments where also recorded in the source PDS, with owner having control to moderate (and then reading comments from the source).

Reality: it's usually your internet provider that controls the name resolution - and the 'DNS resolver' setting gives that control to you. Install K8S - you get a parallel domain name system.09 Dec 2024 16:23 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lcv57e5h4k2khttps://bsky.app/profile/costinm.bsky.social/post/3lcii7ufndc2mNot sure - the point of different accounts and (plc) DIDs is to create different personas that are NOT linked. Professional and personal/'fun' accounts. Linking and verifying all identities (principals) of a subject is a great idea, so is the liberal (or literal) interpretation of the spec.04 Dec 2024 15:36 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lcii7ufndc2mhttps://bsky.app/profile/costinm.bsky.social/post/3lcenu6d75s2xExperiment with GitHub pages, DIDs and comments - https://costinm.github.io/well-known-github/03 Dec 2024 03:06 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3lcenu6d75s2xhttps://bsky.app/profile/costinm.bsky.social/post/3lc55arego22lFeature request: allow subscribing to a blocklist, as a feed.

And the PDS is effectively hosting content like a web server. Could it also proxy the rest to some routes ?

Run a private PDS watching K8S changes, signing them - and distributing.

Not perfect - but many good things that can be reused in k8s or Istio.15 Nov 2024 14:52 +0000at://did:plc:uuqeqhfxq2fccgf3d2kpbtor/app.bsky.feed.post/3laymuw5et22v
