jchampem··on Show HN: IAvisa – Explore visa requirements worldwide
I think this is a very though subject and cannot be treated so easily.

Visa policies might be very different from one country to another, updated quiet often etc.

What you believe to be the source of truth on the internet might not be the actual truth. For personal reasons I recently had to know whether or not a Visa was required for a personal short travel to Russia for a Mauritius citizen. Various information can be found on the internet, some says yes, some says no. Your website says a visa is required. However, a visa is not required in this case.

It's very tricky to get the correct information, always up to date, and your website can lead to people having issues entering a country.

It also applies here in France, especially northern/eastern parts close to Germany.

Well, not for Chantal, which is not a very exotic name here.

jchampem··on Apple App Store Principles and Practices
"A store that welcomes competition."

I thought they wouldn't dare listing web browsers in that competition... well they did.

It's cool after all, average users have no idea about the difference between a browser and the engine...

Pimorini (I think they are quite famous as Raspberry Pis retailers in Europe) recently started a kickstarter for another handheld console: https://www.kickstarter.com/projects/pimoroni/32blit-retro-i...

jchampem··on Macron Vowed to Make France a ‘Startup Nation.’ Is It Getting There?
Thanks a lot! I don't plan to subscribe right now, maybe I will in the next 6 months or so.

May I ask what is that online accounting service?
jchampem··on Is the open office layout dead?
Well, they already planned that all of us will have a laptop + a cell phone. (We don't get to choose our hardware so desktop PC is not an option...)
jchampem··on Is the open office layout dead?
At my current job, they plan to move office and to change the organisation from "open office layout" to what they call "dynamic layout", including no designated desks.

And they made some studies stating that an average of X% of the company workforce time is spent in meeting rooms, so they can cut off the number of desks by X% (minus a small delta).

People will even have lockers to store personal stuff...

I'm looking forward to see how that will work, have a good laugh and quit.

jchampem··on Cannes Will Ban Streaming-Only Movies from Competition
As a Frenchman, it makes sense to me.

Imho, watching a movie at home or in a theater are totally different experiences.

At home you can get interrupted by anything (phone call, email, notification), whereas in a theater the risk of getting interrupted by something external are lower. (I agree though, that I could airplane-mode my devices at home.)

Also, the ambience in a theater is much more different than at home, especially for comedy and horror genre.

jchampem··on A Visa for founders, engineers and investors willing to join France
Afaik, rents in London are pretty outrageous if you don't want something at the far end of a Tube line...
jchampem··on A Visa for founders, engineers and investors willing to join France
Exactly. The first 25% I mentioned includes health insurance for your whole family with close to 0 deductibles (usually a few euros here and there), retirement plan and unemployment insurance (if you get fired, you can expect to get ~60% of your previous gross salary the first year, slowly decreasing after that) and at the very least 5 weeks of paid annual leave.
jchampem··on A Visa for founders, engineers and investors willing to join France
This seems to be accurately calculating the income taxes, but that's not taking into account the corporate taxes.

If a French employer tells you they'll pay you 100k€ annually (just for the sake of the example), you can expect to receive 75k€. (25%, mostly for your retirement plan, social security and unemployment insurance. Mandatory)

Then, if you input those 75k in this tool, it will tell you what you can expect to pay as income taxes. In the case of 75k, 17 218€.

jchampem··on A Visa for founders, engineers and investors willing to join France
You can expect something from 50k to 70k€ (gross salary) dependending on the company and your experience.

Remove 25% of that to have an idea of your net salary. (Those 25% are mostly for your retirement plan, social security and unemployment insurance. All of those are mandatory)

Expect to pay between 1 and 2 months net salary in yearly incomes taxes.

The title of the post is not really clear.. Maybe it should state that they are building a datacenter in a Nuclear Fallout Shelter in the middle of Paris?
