I’d recommend taking it even further and mapping capslock to escape when pressed by itself and CTRL when held in sequence with another key.

New comment by poxrud in "Writing Composable SQL Using Knex and Pipelines"

poxrud — Thu, 28 Nov 2024 18:55:39 +0000

I've used Knex, ActiveRecord and many other ORM's and query builders. At some point, beyond basic queries you start wasting time coming up with SQL statements and then having to convert them to your ORM/builder's syntax. I've reached the point now where it's just easier to stick with writing SQL and having a library that removes the possibility of sql injections. My current stack is postgres.js and dbmate for migrations.

That is incorrect, as per the article Kia ties the VIN number to the car’s functionality. The author used a 3rd party service to convert the license plate number to VIN.

Do you support S3 event notifications?

It’s much more than just generating structured schema. It also understands user intent and assigns the correct functions to solve a query. So for example if we give it two functions getWeather(city) and getTime(city) and ask “what’s the weather in New York?” It will decide on the correct function to use. It will also know to use both functions if we ask it “what’s the time and weather in New York?”.

New comment by poxrud in "TV Station Launches Multiple 4K Broadcasts OTA on ATSC 1.0 [video]"

poxrud — Sun, 17 Mar 2024 15:09:19 +0000

ATSC is a North American modulation standard for transmission of Transport Streams over RF signals. Transport streams can carry any kind of a payload, including data. When the spec came out it was mandatory to use mpeg-2 for video encoding because that was the popular codec at the time. However there is nothing in the spec preventing broadcasters using other video/audio codecs (many already do). This is what this tv station did. You have approximately 19mbps of bandwidth to pack in as much payload in there as you can fit. ATSC3 brings about other features such as higher bandwidth, improved RF signals transmission efficiency (lower costs), error correction, etc…

poxrud — Fri, 15 Mar 2024 14:27:07 +0000

IAM is complicated but it doesn’t have to be, as long as you keep things organized.

- Use AWS Organizations to organize your teams into Organizational Units

- use SCP to limit permissions of the OUs.

- let the OUs create new aws accounts for every project/workload

- now you have permissions and costs organized per project/workload

Don’t be afraid to create many AWS accounts, this is encouraged and considered best practice.

This is the best way to connect to your instances. However you still need the SSM agent installed and the right IAM permissions.

It’s a way to represent a range of IP addresses. Using CIDR notation. https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

OP is saying that they have control of 1022 public IP addresses.

For many cases yes. With llm based embeddings you get “semantic search”, so for example if someone searches for “pets” they will most likely get results that include “dogs” and “cats”. This is not the case for regular text search.

You do need a database if you want the ability to log users out server side. This is usually done through a second refresh token.

I know it’s not the same but you can setup billing alarms and budget alerts.

New comment by poxrud in "EV Chargers Should Be Dumber"

poxrud — Wed, 30 Aug 2023 19:00:16 +0000

In Canada the supercharger experience is great. In 3 years I’ve never had to wait for a spot. The superchargers are usually located in convenient locations in mall marking lots or next to coffee shops or restaurants. I’d love to switch try a different EV but the lack of a supercharger network prevents that.

I've made it a habit to only create IAM roles/users/policies using CloudFormation. This way they can be easily removed, are version controlled and you can see why they were created in the first place.

As a counter example, I love learning new languages and frameworks. Reading a “Getting Started” tutorial is as interesting to me as picking up a new book. That’s what I like about public cloud, with hundreds of services there is always something to learn.

Is this an alternative/competitor to langchain? If so which one is easier to use?

It’s still the fastest and most common way to get aws cli working on a local dev machine.

“That would incur a fixed cost of around $32k for the migration.”

They should consider Backblaze b2 if they want s3 api compatibility. Backblaze currently offers to cover the migration costs assuming some spend commitment.

You have made a lot of incorrect assumptions about me, so I will stop participating in this discussion. For anyone else reading this please know that if you visit Ukraine you can bring with you a book in Russian or in any other language. Furthermore feel free to walk into a local bookstore and purchase a book in Russian.
