Hi beforeolives— I like your breakdown, and I've observed similar things in my experience as an engineering focused data person! I've had many discussions with my colleagues about how to manage effectively these different blends o

We are agreeing that NYC is not at a moment of urban collapse. The processes that drives away the tax base includes policies and social and market forces that erode the city's effectiveness as a sustaining economic and social hub. The

I had the same initial thought based on the title. Unfortunately, the answer is no. The article discusses a low-dimensional KNN problem. The curse of dimensionality guides intuition that the methods here likely will not apply to extremely h

At Frame.ai, we are using both PostgreSQL and faiss (and other tools) in our stack to do several different kinds of inference tasks on semantic representations of text to help companies understand and act on customer chats, emails, and phon

It's built into the inbox view, so GMail is extracting the action from the message content and placing a button on the row element. Sorry if that wasn't clear from my initial post.

GMail seems to have opened a vector to amplify dark patterns by placing action buttons on messages. My least favorite is the LinkedIn accept invitation button, which I've clicked now several times by accident because I've spent ye

For query plans using a sort node, there can be a major difference in performance depending on the row width.

It's worth mentioning that it's a bad idea to invalidate refresh_token grants ever during the lifetime of an authorization. I've seen APIs do this immediately upon sending the response to the token endpoint, which makes the s

Your response highlights a good idea to mitigate the risk I was trying to highlight in mine. They want to have a rapid response path (little to no delay using staging envs) to respond to emergencies. The old SOP allowed all releases to use

Appreciate the detail here. It's a great writeup. Wondering what folks think about one of the changes: 5. Changing the SOP to do staged rollouts of rules in the same manner used for other software at Cloudflare while reta

The other part of this story I did not see mentioned is that I suspect that password expiration also makes organizations more vulnerable to social engineering hacks because legitimate users (I have done this) become locked out due to poorly

Kinesis is not necessarily well-suited fan-out. It is very well suited for fan-in (single consumer, multiple producers). Each shard allows at most 5 GetRecords operations per second. If you want to fan out to many consumers, you will reach

Pick up some data sheets for IC parts that might be useful in a system you'd like to design. These are published by the manufacturer, and they contain a lot of design requirements about how to layout properly a PCB and some about the t

You're correct that a table-level lock is a useful tool to ensure serializability, but it's also a drastic one since it blocks other transactions requesting a higher access level. The concurrency control system is trying to provid

by blr246 7y ago
To implement the serializable isolation level, the database system must track access to every single row you access, even the ones you read or filter out. (The need to track reads, even for rows filtered out of a select statement is surpris

Agree this is pretty much inexcusable. Logging request or response payloads without an explicit whitelist should raise flags for any developer. There are very few cases where you can assert that not only in the present but also for all futu

Great write-up. Is the long-term vision to go completely to the vectorised query execution model, or are there cases where a row-oriented plan might be better, such as cases when there are complex computations involving multiple columns of

This is a great tool. We use it to generate an Entity Relationship Diagram from our canonical DDL file checked into our repo. Here's the basic recipe: 1. Spin up a fresh Postgres instance on Docker using -P to claim an available ep

This "asymmetry" is one of the reasons why having capital makes you powerful, and living paycheck-to-paycheck (maximum need for liquidity) makes you powerless.

Wholeheartedly agree. There are so many powerful development and debugging tools that are easy to configure in a standard IDE outside of a container environment. Docker is an excellent packaging and deployment tool. During more than 3 years

Vault has always appeared to me to be a great technology for a larger tech org looking to implement more granular access control and increased auditability. At a smaller scale, we've been satisfied with encrypting secrets using KMS and

A major problem with this is that non-expert users might interpret it to mean that the "green lock" always means everything is ok. That is dangerous advice since it's possible to publish a phishing site having proper SSL. Use

I think there's a crucial component missing from a lot of the good advice here: pick a couple of languages to learn deeply enough to get into the language specification. To really appreciate the interplay between code and execution, yo
