it's 35M 1024 vectors Plus the text
tjake··on Jlama (Java) outperforms llama.cpp in F32 Llama 7B Model
The default for `convert.py` is F32. This is just SIMD CPU comparison.

Jlama uses the vector api in java20 but also better thread scheduling with work stealing and zero allocation.

tjake··on Which vector database should I use? A comparison cheatsheet
Missed AstraDB (Cassandra based). It ticks all the green boxes (HIPPA, SOC II, Cloud, in DB etc..)

tjake··on Elassandra: Elasticsearch implemented on top of Cassandra
This is close to my heart, I love these integrations!
tjake··on The strange fate of a person falling into a black hole
sounds cool, except before you even got close close to the black hole you would be ripped apart by the tidal forces.
tjake··on I will not sign the CLA for less than $100, payable in Bitcoins in advance
The CLA protects users of the software from contributors coming back later and saying: "Hey I own that code and now you need to pay me!" Apache projects in general rely on CLA documents.

It's totally in the right of the contributor to refuse to sign this document. But don't expect your contributions to be applied, or work on any Apache licensed projects :)

tjake··on Consensus on Cassandra
I'm not sure though what you mean by "tied together".

This is the issue that even zookeeper has.

tjake··on Consensus on Cassandra
Agreed. They discuss this in the chubby paper as well.

There is a grace period where the master is in jeopardy of failing over vs failing over straight away. I left this out for simplicity of the state machine but I pointed to the chubby paper as a true reference.

They also mention the fact that client and master clocks must advance no faster than a known constant factor.

tjake··on Why Cassandra Doesn't Need Vector Clocks
bq. I also see Cassandra timeouts while writing with consistency ANY, yet are still somehow getting timeouts with this operation. That really screams to me that the cluster is truly messed up.

This was a issue with atomic batches and CL.ANY we've fixed since the test.

tjake··on Resurgence of Neural Networks
Yeah I thought the A.I. categories would get some feedback like this. It's a huge field.
tjake··on Resurgence of Neural Networks
Tell him about it :)
tjake··on Resurgence of Neural Networks
Oh sorry. I fixed it. Sorry Geoffrey!
tjake··on Cassandra cluster monitoring tool
It's free for production use now...

You can either allow traffic between one or more subnets, or put gossip traffic on a private network.

The site lets you search twitter lists or the people you follow on twitter, rather than all of twitter.

tjake··on Ask HN: Review my twitter search app
The only way to access your personal twitter stream is via authenticated access, like any other twitter client.
tjake··on Ask HN: Review my twitter search app
twitter api limits us to your history, we could resort to scraping perhaps?
tjake··on Ask HN: Review my twitter search app
yes we index your tweets so you can search them. if you never come back to the site we stop indexing them.

You can revoke access to the app from here http://twitter.com/account/connections

We don't yet support full delete of all history, but it's on our list.

Also, we are adding support for an api so you can interact with the site/export your history programatically.

tjake··on Ask HN: Review my twitter search app
this does search history from the point you create your account :) thx for the feedback.
tjake··on Ask HN: How many kids do you have?
Yeah, I know what you mean. I'm in about the same situation. But I save the beer for the weekends and code :)

tjake··on Ask HN: Worst working conditions you have written code in?
yeah, no tunes, and i just couldn't get used to the sweaty hands from the gloves. i forgot about the mask. those dark red lines in your face, i much prefer my aeron chair and office now :)
tjake··on Ask HN: Worst working conditions you have written code in?
Wrote custom test-set software in a clean-room. Bunny suit, mask and rubber gloves for 8 hours a day. It was a windows box connected to a x-ray diffraction machine so I had to be in the room.
