archit3cture··on The surprising impact of medium-size texts on PostgreSQL performance (2020)
This comment does not address the content of the article. I would be interested to know what tool is used to generate the svg table figures.
archit3cture··on Fire declared in OVH SBG2 datacentre building
in case there were not posted before, here are pictures of SBG2 in flames taken by the firemen. https://twitter.com/xgarreau/status/1369559995491172354

This puts an image on the sentence "SBG2 is destroyed". Do not expect any recovery from SBG2.

archit3cture··on Show HN: GridRoyale, a life simulation for exploring social dynamics
I rencently read a book that touches on such social simulation - "An Introduction to Multiagent systems / Michael Wooldridge".

He mentions p.214-218 such a grid like social simulation that was done in the EOS project, undertaken at the University of Essex in the UK. The goal of the EOS project was to investigate the causes of the emergence of social complexity in Upper Palaeolithic France and they were using a 10000x10000 grid.

You could also be interested in "Simulating Societies using Distributed Artificial Intelligence / Jim Doran"

archit3cture··on NYU DS-GA 1008 – Deep Learning
I wonder what is a good hardware setup for following this kind of course and seriously play with deep learning in general (outside of an enterprise context where the enterprise would provide the hardware). What kind of budget should be considered ?
archit3cture··on Ask HN: Thoughts / Experiences on SQL as an API
Regarding YQL, I found this github repo - https://github.com/yql/yql-tables that seem to describe some of the external tables that used to be available through YQL.
archit3cture··on Asana S-1
In the "History" section (p.2) they state that

"We started Asana because our co-founders experienced firsthand the growing problem of work about work. While at Facebook, they saw the coordination challenges the company faced as it scaled. Instead of spending time on work that generated results, they were spending time in status meetings and long email threads trying to figure out who was responsible for what. They recognized the pain of work about work was universal to teams that need to coordinate their work effectively to achieve their objectives. Yet there were no products in the market that adequately addressed this pain. As a result of that frustration, they were inspired to create Asana to solve this problem for the world’s teams."

I can only imagine that the complexity of the coordination inside Facebook continued to grow after Asana was created.

So is Facebook a client of Asana to solve this problem ? How does a company like Facebook handle the "coordination problem" ? Do they have one tool that solves all the issues or a myriad of project management tools ?

archit3cture··on Relicensing CockroachDB
It is nice to see that CockroachDB's team keep their original vision of creating a long term open source "commons" of their database.

What I don't totally understand when I take my developer's hat is why the split between "enterprise" features under CCL and core features under APL/BSL is kept. Without the "enterprise" features, CRDB does not feel like beeing totally open source and open source users are sort of second-zone users.

Are open-source fans supposed to write clean-room implementations of the features (would it even make sense in the licencing model CRDB uses) ?

It would also be nice to have a licencing clause where a change of ownership of CockRoach Labs or the bailout of the company would trigger a licence change for the enterprise features (maybe even after N years).

But as I said congrats on the product and all the best in your commercial endeavour ! may this licence change open new cloud opportunities !

archit3cture··on Streams: a new general purpose data structure in Redis
In the XADD example, you have

XADD mystream * sensor-id 1234 temperature 10.5

to let the server choose an id.

It could also be interesting to have

XADD mystream 1506872463535.* sensor-id 1234 temperature 10.5

to be able to add an element in a specific msec bucket

archit3cture··on Sharding data models
dgraph does try to provide horizontal scaling out of the box. The sharding is done by predicate - cf https://docs.dgraph.io/deploy/#multiple-instances for a documentation link ; I am not sure how it behaves for very frequent predicates though
archit3cture··on Ask HN: What's a side project you built to make money that hasn't?
what level of traffic do you have ? comparison websites were hit seriously when google shopping started to occupy the top of the serps.
archit3cture··on Ask HN: What's a side project you built to make money that hasn't?
maybe try to see if your tool makes it easy to understand viruses, malwares, ransomwares, etc.. Usually there is a time-race to understand how they work in order to find protections quickly. Also the code path is usually convoluted to make them hard to understand. A visualisation could be helpful and have a lot of value for clients
archit3cture··on Show HN: My first native iOS app – Cone, a real time color picker
Great idea ! I wish I had this idea after working on a website that tries to map RGB colors to paint names. An example of result with the Limeade color - http://en.tacolor.com/hex/6fb400/

This does the distance check in the CIELAB color space.
