david_p··on European court of human rights rules obligatory vaccination may be necessary
We already do surrender some rights, like the right to eat your neighbors, which other animals have.

That's what makes us human I think.

It's called the social contract.

david_p··on Citymapper
Everyone uses this is Paris by now. They are especially gaining traction in the last weeks since people use it to know how to reach a place despite all the strikes via whatever means of transportations are currently working.

Integrating real time city bikes data and real time bus times is the killer feature for such a situation.

david_p··on French ISPs Ordered to Block Sci-Hub and LibGen
French here. My understanding is that we have a nationally powerful publishing industry (books, movies, music), thus a powerful pro-copyright lobby.

For those curious:

- the website is copyrighted to Amazon Web Services

- all commits in the github repositories are made by AWS staff.

david_p··on Why Nasa Converted Its Lessons-Learned Database into a Knowledge Graph
To answer your question, yes, there is. The combination of tools used by NASA is Neo4j (database) + Linkurious (enterprise graph exploration tool).

Links: https://neo4j.com/ https://linkurio.us/

More info about this use case here: https://linkurio.us/blog/how-nasa-experiments-with-knowledge...

The screenshot in the article is from Linkurious (without any mention in the article, which is strange).

Spoiler: Linkurious co-founder here.

david_p··on Ask HN: Which abandoned proprietary software would you resurrect?
I still have PSP v7 installed. Using it as an image viewer and photo editor almost daily. I'm also using it to draw in vector mode. It's so fast, so lightweight, and so fully featured.
david_p··on Show HN: Nuclino – A unified real-time workspace for teams
Great UI, great product. I'd use your product to replace prodpad.com anytime :)

> We're already experimenting with different approaches to the graph visualization like visualizing the links between items.

Yes please! Being able to visualize links between items that I created would be amazing.

Coloring items by cluster would be great too: I'd like to have different types of items (some would represent customers, others features-requests, and I'd like to be able to differentiate customers and feature-requests in the graph visually while visualizing links among them).

david_p··on Angular 2 – Best Practises
Actually this seem to depend a lot on the exact search term, look: https://www.google.com/trends/explore#q=%2Fm%2F012l1vxv%2C%2...
david_p··on Angular 2 – Best Practises
It's more mature now that the Angular 1 experiment is over

It's written in TypeScript, so you can write your frontend in TypeScript. Many bugs averted.

You can use a real reactive model (http://victorsavkin.com/post/137821436516/managing-state-in-...)

david_p··on [dead]
As a French living in France: this is neither happening nor debated here.

There are currently numerous demonstrations, going on for weeks, against the latest neo-liberal labor-bill from the government.

Nothing about off-hours emails, sorry.

david_p··on Ask HN: Oldest code you have written that is still in use?
The French epidemic surveillance system I worked on as an intern in 2006.

We basically rewrote the whole system is PHP+MySQL (front end and back office). It was my first time writing PHP professionally and it still seems to be working :)

I guess that's because I'm french myself and selected services that work in my country :)
david_p··on Show HN: Penny, an easy way to track your spending
Looks useful and neat, but remember kids: if you're not paying for it, you're the product. Some of their competition: http://linxo.com (used it for 5 years now), http://bankin.com (used once, preferred linxo).
david_p··on Feeding Graph databases – a third use-case for modern log management platforms
To my knowledge, Neo4j has been working on performances a lot. Neo4j v2.2+ does a much better job with large-scale graphs.

The use-case you describe (a couple million nodes + edges) sounds like a fairly reasonable task for Neo4j.

If Neo4j has been a bad experience for you, I also recommend looking into TitanDB v1+, which scales horizontally (backed by Cassandra), although the query language (Gremlin) is not as easy to learn as Cypher.

david_p··on Feeding Graph databases – a third use-case for modern log management platforms
Since this seems to be trending: any questions about Linkurious or graph databases are welcome. Linkurious CTO here :)

david_p··on France bids to reverse tech brain drain
You comment is actually pretty interesting.

I see a lot of French people convinced that France is worse than anywhere else in the world. Everything that is done in France is seen as "not good enough" by many French. It's an attitude problem and might be the reason why so many of us move away, convinced that "things are better out there".

Maybe the biggest problem with having the state do so much for us is that it makes many people act like spoiled kids: they see things as not-perfect-enough and are easily discouraged.

This is free money man, pick up your phone and call them instead of complaining about their website design :)
david_p··on France bids to reverse tech brain drain
What would you say are the costs to compare to the benefits?

In my opinion, it would have be extremely difficult to bootstrap our company anywhere else. As everyone knows, getting out of cash is what kills early stage companies. We go access to "free cash" (0% loans and more than 100k€ in grants) and some of our employees got paid on unemployment benefits .. I mean, how much further could you go? We survived thank to this benefits.

david_p··on France bids to reverse tech brain drain
Could you elaborate?

Because I see this: http://techcrunch.com/2014/07/01/blablacar-raises-a-massive-...

And this: http://1000startups.fr/?lang=en

And I see Paris being startup-heaven in a couple of years. And things are already pretty nice!

david_p··on France bids to reverse tech brain drain
If you look at the rent, Paris is actually much cheaper than London, NYC and SF. You could go to Berlin of course.

Frankly, if you are an early stage startup with young people Paris is not the cheapest, but you have access to everything: public transportation is free if you are officially unemployed and living with roommates can make everything much cheaper!

david_p··on France bids to reverse tech brain drain
I guess it depends on where you work, like all countries.

I have the exacts same experience as you working at a NYC insurance company (9 to 5 then go home).

I also know at lot of companies here (in France) where people work their asses off everyday.

david_p··on France bids to reverse tech brain drain
it's more than 70% actually.
david_p··on France bids to reverse tech brain drain
Our startup was created in France 2,5 years ago. Here is our experience:

Some of us started working on the project while getting unemployment benefits (huge boost).

We get (very) affordable office spaces from the city and various incubators (we are located in Paris).

We are able to live on first customers + 0% loans from the state + hundreds of thousands of euros in various grants for innovation (http://www.bpifrance.fr/), so we don't need to dilute our shares by raising funds too early.

We get no income taxes for the first years.

Employees have social security. Healthcare is cheap and very good.

Why would we want to start run company anywhere else?

david_p··on Ask HN: What data visualisation tools do data scientists and developers use?
Linkurious CTO here :)

Our product connects to Neo4j databases and enables full-text search, visualization design (select nodes/edges, apply size/color to nodes/edges according to properties) with a point-and-click interface.

Try it out: http://linkurio.us/demo/ (the "create account" button generates a temporary login/password for the demo)

david_p··on Two Uber managers detained in France over 'illicit' low-cost service
So as to make things clear, UberPop has been outlawed in France months ago but keeps operating.

The fines are considered "operating costs" by UberPop, who takes care of paying the fines when UberPop drivers are getting caught.

You can remove the quotes at illicit.

david_p··on The Animatrix
On the other hand, the sites still renders perfectly 14 years later.

It would be interesting to see how today's super-fancy-html5 javascript-everywhere no-tables Websites look in 14 years with a modern browser.

All the "terrible" techniques you mention actually do the job in a surprisingly time-robust way.

Engineering versus hype.

david_p··on UBlock Origin
chrisaljoudi is not pushing anything compared to gorhill, just compare the commit rates: - https://github.com/chrisaljoudi/uBlock/graphs/contributors - https://github.com/gorhill/uBlock/graphs/contributors

I am not claiming that chrisajoudi did anything intentionally wrong, he simply does not contribute as much.
