(Gouach co-founder here) This is nice, but when you have an e-bike with a malfunctioning battery that you use for work everyday, you don't want to have the 2/3 months it generally takes for exchange programs.

Plus, once you sent your battery, they either discard it which is not ideal for the environment, or try to remanufacture it, which is very dangerous when it's done on a battery which wasn't designed for it, like ours

(Gouach co-founder here) Exactly! The first kits are DIY for our early adopters, but we are working on an assembly pipeline in France, China and the US for our models in the coming months. Clients (B2C and B2B) will receive pre-assembled batteries

We are also looking for bike-shop owners who want to train on our batteries (it can be learned in one hour or so) to get a new revenue stream by offering to repair and assemble our batteries!

(Gouach co-founder here) Most of our users buy brand new cells, and we are working with partners who do have the equipment to retrieve second-life cells and match them in their factories, before selling them as "matched second-life cells packs" back to users for a huge discount :)

(Gouach co-founder here) Car-sized batteries last long because they have so much redundancy, that even when multiple cell fails, you barely notice it. It's very different in a smaller e-bike battery packing 40 or 80 cells.

Cells aside, cars have very good suspensions, and their batteries have been designed with very pricey component to eliminate shocks and vibrations.

On e-bikes, most batteries will have to sustain those, and we've seen a LOT of commercial batteries who were out of order for a simple $5 electronics component which was broken, and which couldn't be replaced because the battery was not made to be repaired (soldiering, glue, etc)

We managed to reverse-engineer the protocol and to make our battery communicate with the Bosch controllers!

I really like VoiceInk!

For the Whispering dev: would it be possible to set "right shift" as a toggle? also do it like VoiceInk which is:

- either short right shift press -> then it starts, and short right shift press again to stop - or "long right shift press" (eg when at pressed at least for 0.5s) -> then it starts and just waits for you to release right shift to stop

it's quite convenient

another really cool stuff would be to have the same "mini-recorder" which pops-up on screen like VoiceInk when you record, and once you're done it would display the current transcript, and any of your "transformation" actions, and let you choose which one (or multiple) you want to apply, each time pasting the result in the clipboard

Really nice!

For OsX there is also the great VoiceInk which is similar and open-source https://github.com/Beingpax/VoiceInk/

That's why now I've completely eliminated .env secrets from my codebase and I only use 1Password (with the cli) so it loads secrets dynamically as needed. So if I'm running some AI CLI on my codebase it won't try to leak some secrets

What would be the best Postgres + CH setup to combine both? somethign using CDC and apply them to CH?

New comment by oulipo in "ClickHouse vs PostgreSQL UPDATE performance comparison"

oulipo — Sun, 17 Aug 2025 20:04:26 +0000

Since Postgres is open-source and the kind of database model they use is out there for so long, how come ClickHouse can't have a "postgres subset" (or just include a mini-Postgres) so that it gets the best of both worlds out of the box?

That's really cool! And if before recycling your (ebike) batteries you want to repair them, check out what we've designed in France at Gouach: https://gouach.com

Are those terminal apps open-source / source-available? I wouldn't trust some random app with my server keys

Nobody wants to "view" 1M row... people want to have analytics about what subset of the rows they should look at for a given task

Can you give more details for the un-initiated? What is Mullvad? How and why would you use this feature?

Is it to use it as a kind of VPN to make traffic "appear" from any country, and, eg, watch Netflix?

That's a very interesting article, and a call for more easily repairable products!

That's the kind of thing that inspired us to build a repairable electric battery for ebikes at https://gouach.com !

We want more repair, less planned obsolescence :)
