timvisee··on Ask HN: What are some rock solid open source vector databases
Dev of Qdrant here.

What would change that to 'very happy' in your use case?

timvisee··on Put the zip code first
The majority of comments complains about non-USA. But the author clearly states:

> Fine, maybe country first

It's an example - limit typing. But adjust it to your own use case.

timvisee··on Tell HN: Another round of Zendesk email spam
I've also received about 40 messages, on mail adresses I've never used before.
timvisee··on Do dyslexia fonts work? (2022)
I have dyslexia, and I hate them. It makes me read slower and not better.

I do have two friends who like it. Maybe it's subjective?

Either way, I'm very happy people put effort in developing reading aids like this.

timvisee··on Can Dutch universities do without Microsoft?
In my 5 years I was basically only allowed to use Microsoft tools. It's one of the most stupid things I've ever seen.
timvisee··on Vodafone Germany is changing the open internet, one peering connection at a time
A VPN won't make your route shorter
timvisee··on Two billion email addresses were exposed
The email I have in that list is invalid and must be generated. It's on a domain I own.
timvisee··on Servo v0.0.1
I'm seriously impressed on how far this has come. Tried a few websites in the experimental mode, it renders quite well.
timvisee··on JavaScript Trademark Update
If not now, maybe in the future
timvisee··on Magic/tragic email links: don't make them the only option
I do have a good use case for magic links.

I creates a bar management/sales platform for our group of friends. It's self service so people purchase their products on their phone and pay later.

People get... intoxicated... after which passwords appear to become quite the problem. Magic links solved that.

To solve the multi device and in-app browser problem people can also open the links on another device. That'll show a short code they can enter on the original device to actually log in. It's not perfect, but it works.

I do fully agree that passwords should always be an option as well.

timvisee··on Frosted Glass from Games to the Web: HTML glass UI inspired by AAA game dev
I always feel rendering such blurred panes takes quite a performance hit. Do we have any numbers on this?

I might just be old - when this was done on the CPU.

timvisee··on We Love Writing Software So Much, We're Willing to Do It for Free
While I agree FOSS doesn't give you the right to users money.

It is especially painful if (big) companies make big money with your free product.

timvisee··on Git cheat sheet [pdf]
`git rebase --onto FIRST_ID^ NEW_PARENT`

is also super powerful to put a series of commits on top of a new parent when history has changed.

That happens with PRs and squash merges quite often.

timvisee··on Beware of Base64 Encoded Strings
Does it still do this when piping into things?
timvisee··on Roll-Invert-Unroll: An easier way to replace a duvet cover
It does for me. Firefox on Android.
timvisee··on My favourite animation trick: exponential smoothing (2023)
I don't like this kind of smoothing at all. It feels slow to me. Please just toggle without animations instead. And yes, I know these examples have been slowed down.
timvisee··on Show HN: R2R – Open-source framework for production-grade RAG
Qdrant does this as well, with 100% accuracy. But it's not on small categories, but rather on small segments.

You could put different categories in different shards though, resulting in the same effect.

You can also specify exact=true to do the same on any size, but this can get rather slow when your collection grows.

Disclaimer: I'm part of Qdrant.

timvisee··on We Have to Start Over: From Atom to Zed
And auto vectorization isn't all that common. In many cases you need to structure your code in a certain way, in which case you're better off doing it yourself if you want the vectorization benefit.
timvisee··on Qdrant, the Vector Search Database, raised $28M in a Series A round
With regards to competitors picking similar things up, we've this article explaining why a dedicated vector search service is a good idea: https://qdrant.tech/articles/dedicated-service/
timvisee··on Keeping a long shell history
Fun fact: if you don't want to put a command in history, prefix it with a space. This works in many shells.
timvisee··on Outlook is Microsoft's new data collection service
It handles 150k messages in a folder without a sweat for me. Do you have more?
timvisee··on Half-Life 25th Anniversary Update
Black Mesa (the game) is also factastic. Highly recommend!
timvisee··on iLeakage: Browser-Based Timerless Speculative Execution Attacks on Apple Devices
Another good reason to allow other browser engines on iOS devices.
timvisee··on Hacker leaks millions more 23andMe user records on cybercrime forum
That would make it a bit harder to link to you, but definitely not impossible. It would definitely have been better to not do it at all.
timvisee··on How to Pick a Vector Database – Quantitative Analysis
I think it shouldn't be in this article at all. You're comparing a tool that is not optimized nor efficient in any way against others that are. That while Qdrant has a very well optimized offering as well. This is comparing a walker against modern cars and paints a bad picture.
timvisee··on Bitwarden: Free, open-source password manager
I created `prs` which solves a lot of painpoints I had with pass and other clients.

It is compatible with pass and uses the very same store.

timvisee··on Show HN: Fast vector similarity using Rust and Python
Awesome work!

At Qdrant we do this at scale. Store billions of vectors in a cluster of any size. Also in Rust which turned out to be an amazing choice, and fully open source. It uses various features to keep things performant, such as vectorization (multiple arches), quantization (form of compression) and more.

timvisee··on Vector Similarity Beyond Search
That's weird! A force refresh (CTRL+F5) doesn't work?
timvisee··on MDN Playground
That MDN page has a lot of noise and is not straight to the point. I guess that may be a side effect of JS though.
timvisee··on MDN Playground
Then you haven't seen Rust's documentation yet.
