fijal··on “There is, unfortunately, no such thing as a truly neutral stance on inclusion”
One thing that is completely omitted in the discussion here is that Outreachy is doing something based on your residency (if in US, different rules apply). This is well within their rights, but I wonder how that part affects the "diversity" stance - I would expect a black person from Africa to have generally a much harder time in tech than an African American.
fijal··on Publishers Haven't Realized How Big a Deal GDPR Is
On the other hand, I would prefer to not have my local supermarket sell my data, even at an extra 3% and yet I have basically no option to do that.

fijal··on Ask HN: What are you working on and why is it cool?
https://vrsketch.eu/ - Editing and viewing virtual reality plugin for sketchup. It's a lot of basic research on UI/UX in VR.

http://pypy.org - Python interpreter with a just in time compiler. It's the only alternative python implementation out there, after failures of unladen swallow/pyston etc.

http://bloc11.co.za - Own climbing gym. It's cool to work directly with people and pursue own ideas in a small space.

fijal··on All of Oculus’s Rift headsets have stopped working due to an expired certificate
Imagine how terrible it would be for your customers once that happened in the production....
fijal··on Ask HN: Who is hiring? (March 2018)
Hi stadeshuldt

I can't find your email on your profile. Can you leave some contact details for questions?

Thank you!

fijal··on Show HN: VRSketch – VR drawing tool for architects and designers
Hello everyone.

This is a project by me (Maciej Fijalkowski) and Armin Rigo. We also wrote PyPy (http://pypy.org) and we got quite excited about the Virtual Reality technology. We think VR for architects is a great start for the technology as architecture is an inherently spatial discipline. We welcome any comments

fijal··on HTC’s Vive Pro will add more pixels to an otherwise familiar-looking VR system
We developed a product for editing architecture models in VR (VRsketch.eu). I wonder what company did you try to work with? The potential is enormous, a bit unclear how to sell those though, architecture is a tricky market :)
fijal··on Live CO2 emissions of electricity consumption
That's what you get for having the "green" party in power in Germany - they pushed for phasing out the nuclear and now it looks how it looks.
fijal··on Estonia, the Digital Republic
Personally none - I pay taxes in my home country and everyone is happy. The company rules (delayed income tax, income tax rate) might be subject to treaty that defines "command and control" - that is if the company is really located in Estonia or is it effectively in your home country? If you have an actual office or co founders from other countries or some other vague "company is actually located in estonia", then there are no tax implications of that, other than your personal income.
fijal··on Estonia, the Digital Republic
yes, but you cannot open a bank account. You can use holvi (https://about.holvi.com/e-residents/) but I haven't used it and don't know details on how it differs from a regular bank.
fijal··on Estonia, the Digital Republic
Investigating that topic, but taking card payments is not a part of my primary business.
fijal··on Estonia, the Digital Republic
I tried to sign up for stripe atlas in beta and they didn't want me :)

More seriously - owning shares in us companies create scary tax implications that require some advice when having us clients. US banking system is stuck is in the 1800s and dealing with it is a very serious pain. US legal system, unlike European is very unfriendly for individuals - its just infeasible to do stuff yourself on a shoestring budget, without hiring professionals.

fijal··on Estonia, the Digital Republic
English, stable currency, ability to do stuff online, mature and working banking system. Does not leave many interesting candidates.
fijal··on Estonia, the Digital Republic
Just opened a company in Estonia. The experience so far has been incredible. It's not quite the future - all the technologies should exist everywhere etc. It's the present that should have been, but somehow it's not.
fijal··on Why we switched from Python to Go
Did you guys try PyPy before deciding to switch? If yes, what was the outcome? If not, why not?
fijal··on Rubyist makes some Python code 5x Faster
It would be really good if the author actually linked to somewhere where you can reproduce the benchmark. Either way, I'm pretty sure the correct response is "use pypy", not that I can check it
fijal··on PyPy v5.9 Released
Yes, I'm really sorry.

This is the usual case of budget - if I had budget to have anyone improve the website, improve the buildbot, improve the benchmark comparison, trust me I would do it. Right now there are no volunteers and the benchmark side is sort of lingering on.

fijal··on PyPy v5.9 Released
I would say, if you're familiar with virtualenv and things like that, about 15 minutes
fijal··on PyPy v5.9 Released
It depends: we are heavily invested in making both numpy and pandas faster, so next releases will improve that. That said, you are quite likely to find your program slower (but it really depends on what you do). It's a good time to experiment, but definitely not to fully switch just yet
fijal··on PyPy v5.9 Released
Hi

We should indeed compare PyPy3.5 vs CPython 3.5.3, but having a benchmark suite that works on both continuous to be a problem.

Regarding 2.7.13 - you might find it surprising, but it's actually SLOWER than 2.7.2, there has been no speed improvements and quite a few speed decreases, so we decided to keep the faster one.

EDIT: part of the problem is that comparing PyPy 2 vs CPython 3 is apples vs oranges, but PyPy3 is not ready yet (unicode improvements I'm working on right now are missing)

fijal··on The iPhone X’s notch is basically a Kinect
Can you program it like a kine ct? Or is it essentially a kinect running one program, which makes it a lot less like a kinect (genuine question, I haven't been able to find any info)
fijal··on Read This Before You Build Uber for X
Or just charge reasonable fees for the service provided (booking, billing etc) and not try to abuse it. If the fee is 2-5% noone would bat an eye
fijal··on Let's Remove the Global Interpreter Lock
Hi, blog post author here. Let me put an offer here:

If you want to ask a question that warrants a response (as opposed to promoting your own effort, which is valid but does not warrant a response), please mail me, the mail is public and I'll put the responses publically on either my blog or pypy blog.

fijal··on Let's Remove the Global Interpreter Lock
The concurrent garbage collector has been already written. It probably has bugs, but the basis has been done for the STM effort and redone now. The mess of race conditions is surely not a great place to start, which is why it would take a man year to finish :-) I don't see a much better starting point tbh, but to look at all the mutable data structures in python (of which there are too many) and try hard
fijal··on Let's Remove the Global Interpreter Lock
C API... You can argue it's not a part of the language, but PyPy was forced to support it at the end
fijal··on Let's Remove the Global Interpreter Lock
Maybe selling packaging is a good idea.... that said, kickstarter does not work in any jurisdiction we can use.
fijal··on Let's Remove the Global Interpreter Lock
It removes it for pure python code. The C extensions run under the lock (which is unfair to call interpreter any more)
fijal··on Let's Remove the Global Interpreter Lock
The main issue is that the effort it takes to setup and maintain it greatly outweighs the amount of money we get (typically). There is also complexity with taxation, jurisdictions and all kinds of mess that is usually very much not worth couple dollars (e.g. $7/week on gratipay for example)
fijal··on Let's Remove the Global Interpreter Lock
They would run under GIL (I can't see CPython C API being thread-friendly unless gilectomy succeeds)
