voctor··on Lies I was told about collaborative editing, Part 2: Why we don't use Yjs
I think Y.js 14 and the new y-prosemirror binding fix a lot of the encountered issues
voctor··on The Internals of PostgreSQL
Not related at all but the elephant illustration remind me of the Grand Elephant https://www.lesmachines-nantes.fr/en/discover/the-grand-elep...
voctor··on Writing a simple pool allocator in C
There is a small series of posts on the BitSquid blog about memory allocation which is worth reading! http://bitsquid.blogspot.com/2015/08/allocation-adventures-3...
voctor··on Is my vision that bad? No, it's just a bug in Apple's Calculator
From the post:

> In conclusion, the off-center “x” is real and probably an artifact of the display or how it is rendered. It is unlikely that it is the result of chromatic aberration.

voctor··on Show HN: Atopile – Design circuit boards with code
By reading some code here https://github.com/Timot05/logic-card/blob/main/elec/src/log...

I wonder if with directional arrows, instead of writing "out ~ switch.in; switch.out ~ power.gnd", we could write "out ~> switch ~> power.gnd" instead?

But without distinction between in and out ports it may not be possible to check if connections are valid ones.

Anyway, this project really makes me want to learn electronics! Congrats!

voctor··on Show HN: Atopile – Design circuit boards with code
I've only worked with Akka Graph DSL to build some data pipelines or protocol stacks. And I've loved working with it!

The equivalent of atopile signal would be port with Akka I think. A combination of ports gives us a shape. A source shape is just one OUT port. A flow shape is one IN and one OUT port, etc.

I'm very new to electronics so I don't know if it makes sense, but connecting all these ports with directional arrows was really helpful to understand the data flow.

It reminds me of the Akka Graph DSL[1]

voctor··on Redpanda – A Kafka-compatible streaming platform for mission-critical workloads
> aside from the viewpoint of it being one more external dependency

This is exactly the point. One more dependency, one more executable. Redpanda get rid of that.

voctor··on Tink – Cryptographic APIs that are secure, easy to use correctly
There is also libhydrogen [1] which is a "small, easy-to-use, hard-to-misuse cryptographic library".

voctor··on Google Moves to Address Wage Equity, and Finds It’s Underpaying Many Men
I've often noticed this pattern but only ask myself now, so, yes, in general. From what I remember I never learnt that in school, but I'm obviously not a native English writer. @Raphmedia already gave me a good link, but thank you for the one you gave me too.

Off-topic: Why almost all words in the title begin by an uppercase letter?
voctor··on Show HN: X-spreadsheet – A JavaScript canvas spreadsheet for web
This is really interesting! I've hoped of a scenegraph based web in the past, all rendered in a canvas (indexing can be done by serving a simplified html representation by checking the user agent). I think the most challenging part is text rendering, but some people have done some work in this area (https://github.com/astiopin/webgl_fonts). Also, we may need some sort of API to trigger keyboard showing on mobile device. Anyway, congratulations!

voctor··on Apple T2 Security Chip: Security Overview [pdf]
They say that "The camera is not disconnected in hardware because its field of view is completely obstructed with the lid closed."
voctor··on Apple T2 Security Chip: Security Overview [pdf]
If the trigger is mechanical it's ok, but if the trigger is electrical (and handled by some hardware) then the chip is useful.
voctor··on Apple T2 Security Chip: Security Overview [pdf]
"All Mac portables with the Apple T2 Security Chip feature a hardware disconnect that ensures that the microphone is disabled whenever the lid is closed." It's interesting, I don't know if other brands do that?
voctor··on Spent – Poverty Simulator (2011)
People do car-sharing in the US? I've seen many countries where cars only drive their driver on the way to work.
voctor··on How to get rich without getting lucky
Yes, someone can be considered poor because the only thing he/she got is money.
voctor··on LocationSmart Leaked Location Data for All Major U.S. Carriers in Real Time
Maybe this is not a security vulnerability, but a feature, intentionally put here as a backdoor. This would not be the first time such behaviours are observed.

voctor··on GitHub is down
Momentarily, yes. But it's just another central hub.
voctor··on Citus Unforks from PostgreSQL, Goes Open Source
Yes, but Citus can also parallelize on multiple cores when used on a single machine ("If you’re running Citus on a single machine, this will scale queries across multiple CPU cores. and create the impression of sharding across databases."). Will this functionality becomes obsolete with the 9.6 ?
