How to scrape any public Telegram channel without the API (no phone number, no login)

·1 views

There are two usual ways to read a Telegram channel from code, and both are annoying: Bot API: a bot only sees posts from channels where it's an admin, so it can't read someone else's channel. MTProto (Telethon / Pyrogram): works, but needs an api_id/api_hash from my.telegram.org, which is tied to your phone number. You also manage a logged-in session, and risk your account if you scrape hard. There's a third way that most people miss: every public channel has a web preview at https://t.me/s/ . It's plain HTML, needs no login or account, and contains the full post text, date, view count, react

Multimodal AI Breaks at the Tokenizer, Not the Model

TL;DR — The gap between a multimodal demo and a production system isn't model capability — it's the token economics of turning video and audio into sequences the transformer can read. Naive frame sampling and fixed-window audio chunking quietly blow up cost, latency, and accuracy long before the language model does any reasoning. Treating modality ingestion as a retrieval problem, not a context-stuffing problem, is the fix most teams skip. Every multimodal demo follows the same script: drop in a short clip, ask a question about it, watch the model nail it. Then someone tries it on a forty-minu

Then I thought about what most of my batch is doing right now. We're all applying for our first jobs. And if you're a fresher looking for a job, you're exactly who fake job offers are aimed at. They look something like this.

Your Agent Said "Done". The Filesystem Disagrees.

"Task completed successfully." That's the most common lie in agent systems. Usually the agent isn't lying on purpose.

How to know when a dependency changes your day

Watching every release is not monitoring. It is a second inbox with a package name on it. Open your package.json. Count the direct dependencies. Now multiply by roughly one release every few weeks, and you have the number of events per year that a tool watching your dependencies could send you.
