best of luck to you, it will be great to see a rearchitected postgres.

Are you fixing the heap and table management ?. Postgres does not use an undo log and manages all table updates directly in table storage which slows MVCC.

also have you told Ben Dicken ? https://x.com/BenjDicken/status/2074326407795417435

A credible journalist would not entertain writing a story based on a screenshot some random user posts on social media.

Yes people frequently fake screenshots on social media. I'd want either a screenshot from a credible person, reporting from a journalist, trusted blogger, company statement etc.

Is there actual proof that they are doing this. Theres not much to go on in the tweet.

VHDL is not a language for spatial design. Its more akin to a programming language with circuit semantics.

> Most people will make the lazy choice. But you can choose to do otherwise

I'd like for it to be a choice. AI is injected into search now, when you install vscode they have a prompt input sitting there and they nudge you to use it. Of course you can opt out of this stuff but it has become the default.

As someone teaching their nephew how to code i really want him to struggle and exercise his problem solving skills instead of having every touchpoint offer him an instant answer.

Does the model have capacity for in context learning ?, if we give it examples of patterns can it follow them ?.

In a traditional SLAM pipeline you do periodically fix drift by detecting when you've visited an area that you've mapped before this lets you align your sub maps so they are globally consistent.

In the areas you have visited previously you have two estimates of your position one from your frame-to-frame estimates and another from the map you built of the area the first time. You can then solve an optimization problem to bring those two estimates closer together.

In order to find out if you've already visited an area you store a description of the locations in a DB and search through them. The paper says they use a compressed representation of the "maps" and use test time training to optimize the global consistency between their sub maps.

Sure but the exploit here isn’t prompt injection, it is an edge case in their billing that isn’t attributing agent calls correctly.

LLMs sample the next token from a conditional probability distribution, the hope is that dumb sequences are less probable but they will just happen naturally.

Had this same experience back when I first learned to program a PIC microcontroller. You really shouldn't be driving LEDs directly off IO pins anyways. I think the digitalness of IO pins also lends itself to not thinking about the underlying circuitry and coming at it from a software lens.

theres more information here https://docs.usetero.com/introduction/how-tero-works the link in the article is broken.

They determine what events/fields are not used and then add filters to your observability provider so you dont pay to ingest them.

> So "stripe webhook" matches /services/stripe/webhook.handler.ts highly because the path literally contains both terms in logical positions

This sounds a lot like document search ontop of your specific attributes and you have a custom ranking algorithm.
