Proton VPN (https://protonvpn.com/) | Senior Performance Engineer | Barcelona, Spain or Geneva, Switzerland | ONSITE

Proton VPN enables millions of people to connect securely and privately, even in places where the internet is restricted or unreliable. Delivering that experience means our service must perform flawlessly under highly variable, real-world conditions.

We are looking for a Senior Performance Engineer to lead our efforts in making Proton VPN the fastest, most resilient, and most reliable VPN service in the world.

You will define and drive the measurement, analysis, and optimization of Proton VPN’s end-to-end performance, across clients, platforms, and global infrastructure. You’ll help ensure that every connection is fast, stable, and private, regardless of where the user is or what network they’re on.

We're looking for candidates with experience in system-level development (e.g. C or C++ or Rust), and network engineering (experience working with UDP/TCP and VPN protocols).

kaplun··on Founder Mode
A founder lives their company as the most important thing in their life, it's an extension of their life and they live and breath the company. A manager instead is being given a responsibility and will try their best to fulfill the role. A founder will never rest if they know there's an issue to be solved in the company, while the manager has a life and know they can move forward in case. A founder will not be intimidated by any internal policy or rule if they believe they need to change something. A manager will try to play by the rules, and in case try to modify them through influence. A founder is basically a ruler who truly care about the success of the company (not necessarily about the happiness and fulfilment of the people taking part in the company). For a funder the Company comes first, before anything else.

kaplun··on A living replacement knee to be tested in clinical trials within five years
I got one hip replaced in my thirties with titanium and ceramic. I am so glad I did it. I can't run too much but, beside that, I got back entire mobility after couple of months. More than 10 years have passed and it's like not having a prothesis. Ceramic was suggested by doctor as it lasts longer (though it's more fragile in case of accident).
kaplun··on Introducing Proton CAPTCHA, the world’s first censorship-resistant CAPTCHA
This is not true. We moved longtime ago to use hCaptcha precisely to cut ties with Google reCAPTCHA. And we switched today from hCaptcha to our own solution precisely for the reason described in the blog post.

The problem is not that everybody can access information. The problem is that click-bait false information is pushed by ranking algorithms more and more in front of the eyes of people who are ready to believe in them. The information bubble then is making people more and more radicalized.

They are probably right. After a PhD, and 2-3 postdocs you end up being 40, out of the domain, and the most probable job available will be data analytics for a bank, when your real dream was the Nobel prize...

kaplun··on Scientists In Alaska Find Mammoth Amounts Of Carbon In The Warming Permafrost
I always thought about cycling to work, but that would mean more than doubling the amount of time commuting and thus complicating the family organization (basically my wife, who is also having a full-time job, would need to take care of everything, while I am polluting less). So far I haven't found a definite solution to how, in the modern world, work at least 8-10 hours per day, possibly far from home, while having a family, and not polluting.

Do these specific changes from Google impact negatively the community? Otherwise, IMHO good ideas, are good ideas regardless where they come from.
kaplun··on Net Neutrality’s Holes in Europe May Offer Peek at Future in U.S
Yup, I was mentioning explicitly Orange, because a friend of mine got the nasty surprise after trying to enable tethering.

And this option was not in his normal subscription, although it was a subscription with quite a nice Data plan.

And this violates Net Neutrality because Orange is deciding what you can do or not with your paid bandwidth.

kaplun··on Net Neutrality’s Holes in Europe May Offer Peek at Future in U.S
In France, the main mobile operator Orange, offers you tethering only as an option to be additionally paid on top of your data plan. They basically monitor the connection to check if your mobile is forwarding packages and do mitm in order to display advertisement about the additional paid option.
