lpasselin··on LeafletJS: a JavaScript library for interactive maps
Leaflet is great for polygon annotations. It is used by Labelbox and Supervisely.
lpasselin··on Postgres.app
I don't know much about Nix.

But is there really any isolation if it's installed on your host os? I always thought Nix was primarily a package management tool. Like brew?

Docker isolation is different.

lpasselin··on Postgres.app
You mean Nix as a base image?
lpasselin··on Ask HN: Who wants project feedback? (August 2021)
I bought and use usertrack.

Your landing page is not perfect aesthetically. It makes it feel genuine and that's what convinced me to try your product.

You have a great page and product. I'm jealous of your project. Please continue what you're doing!

lpasselin··on Tomato fruits send electrical warnings to the rest of the plant when attacked
Does anyone have papers like this to recommend?

I am really interested in building custom systems to experiment with plants. My problem is that I don't know what to test.

Who knows what's in that soil?

You can use the same plastics as in water pipes.

lpasselin··on Runway – Create impossible video
The models they are using are probably already public.
lpasselin··on Responsive images
For those wondering, JPEG XL is not currently supported by browsers https://caniuse.com/jpegxl

Progressive JPEG is already supported but JPEG XL seems much better.

First time I hear about JPEG XL. I have experimented with progressive JPEG a couple of years ago but switched to webp since the various public Google page scores give a better score for images in webp.

lpasselin··on VSCode, Dev Containers and Docker
This is what I used (combined with stackoverflow posts) to try it.
lpasselin··on VSCode, Dev Containers and Docker
Not how often people switch companies but how often people work on different projects. Someone working on multiple projects can waste a lot of time keeping up with the environment of each project.
lpasselin··on VSCode, Dev Containers and Docker
One slight problem I had with .devcontainer in VS Code was running the devcontainer on a remote ssh server.

Remote SSH works. Local devcontainer works. But mixing the two requires configuring the docker engine settings to point to the remote. This forces other projects to also run on the remote machine.

This was a problem as of 2 months ago.

lpasselin··on VSCode, Dev Containers and Docker
Have you tried docker on Windows? It's even worse.

On OSX I only had problems with GUI running in docker. I was used to sharing X between linux host and docker container also running linux.

For some projects, the only working solution I found was to run a VNC server in docker. Specific example: in a docker container, run a GUI built with Kivy and view the window on the OSX host. If anyone manages to do this without VNC, I'd like to know how!

lpasselin··on VSCode, Dev Containers and Docker
Consistency between team members.

Super easy for new team members to get started on a project. No need to manually install dependencies.

Environment versioning in git and docker. Your local environment gets automatically updated with a git pull.

How fast is apple to fix bugs like that? I am also affected.
lpasselin··on Show HN: Deep learning tool that repairs damaged/faded photos
They reference this paper: https://github.com/microsoft/Bringing-Old-Photos-Back-to-Lif...

For which the models are available online. No need to train in this case.

If this was a new project and you were starting from scratch but already had a clean dataset, 0.5 to 3 days of work (excluding training time).

The model is a VAE so I would approximate less than 2 days of training time on a modern GPU.

lpasselin··on Ask HN: How to Become a Consultant?
This is what the typical hacker News poster says. It is a lot of work and will take a lot of time.

An other way is to get in touch with your contacts working in companies that have problems you can solve.

lpasselin··on Ask HN: How to Become a Consultant?
I've done a few contracts as an independent in the last two years completely agree that sales is the most important and is also the hardest.

I disagree with you when you say problem is the 0 to POC/MVP (excluding sales). I think that is the easiest and most fun part of a project. The hardest is 0 to first line of code.

When you complete part of the POC/MVP and it seems to be working, clients understand what you are worth.

In my experience, after the POC, managers had no problem boosting the budget because you've proven you can do the job and there is low risk in giving you more work and freedom to continue adding features.

I might have been lucky to get along really nicely with all of my clients yet.

Finding the initial problem is the hardest for me. All of my contracts were from previous contacts and someone knowing someone...

If anyone has it the other way around, I'd love to learn more.

lpasselin··on Designing an Overkill workbench for home office
These are great. I kind of regret my ikea karlby.
lpasselin··on Launch HN: QuestDB (YC S20) – Fast open source time series database
This is great if it works well. Drop-in replacement would be great for systems with DB abstraction like in django, sqlalchemy.
lpasselin··on Launch HN: QuestDB (YC S20) – Fast open source time series database
Does postgres wire support mean QuestDB can be a drop-in replacement for a postgres database?

Is this common?

lpasselin··on SymPy - a Python library for symbolic mathematics
Last time I tried sympy was to simplify a function including dot products. In 24h it was not able to converge.

Anyone has tips to reduce time required to simplify?

lpasselin··on Detecting a 2.4 GHz transmission for under 1 EUR
Yes. I got one from AliExpress for 30$ including the 12V psu. It works fine if you aren't working with super high frequencies. I use it mostly as a voltmeter.
lpasselin··on New ways to make vertical farming stack up
You might be interested in user superangryguy on Reddit.

He experiments with led and has detailed information on LED and plants.

He has a patent for growing smaller plants, by lighting with blue light on the stem.

lpasselin··on Virtual Kubernetes
It cwould B useful to run multiple clusters for home/work but using a single cluster.

I would like to be able to let my clients start jobs and use their private cluster and append their machines to it, running in my cluster.

Is there a way to do this with kubernetes currently?

Very creative use of an autoencoder!

lpasselin··on Bitcoin climbs to $10k
I don't think it is linked to Libra. The price if Bitcoin has been slowly rising for a while now.

During the last 3 months, when my stocks are red, Bitcoin is green.
