donjoe··on Tesla – Great things are launching at 2pm
Does anyone have any experience with Tesla's electric door handles (Model S)? How do they perform in wet/cold climate where it freezes during the night?

And then there is the falcon wings: any experiences with snow on the roof while opening the doors?

donjoe··on German for Programmers
It depends on the word. Der oder das Radio for example: das Radio(gerät) oder der Radio(empfänger) defines the article. The same can be distinguished for butter: the word's origin might originate from Greek or Latin - depending on which language you choose, you'd get a different article.
donjoe··on German for Programmers
Well, sometimes Germans themselves are not quite sure about which article to use. It differs from north to south, from east to west and depends a lot on the dialect you're used to.

An (Upper-)Bavarian would for example never say "die Butter". It is and will always be "der Butter". Same with "der Radio" in the South and "das Radio" for the rest of the country.

Another funny thing I stumble upon every time Oktoberfest starts: Oktoberfest in Munich is referred to as "die Wiesn" (the lawn/grassland). Bavarians don't know an 'e' in the end of a noun, they will therefore always replace it with a 'n'. In the rest of Germany, Wiesn doesn't exist. It's either 'Wiese'(sgl, a single grassland) or 'Wiesen' (pl, many grasslands). Since Wiesen sounds more similar to 'Wiesn' than 'Wiese', even newspapers regularly refer to the Oktoberfest as a multiple of 'Wiese' which - for us - sounds just wrong: "Heute sind wir auf den Wiesn gewesen".

donjoe··on Write tests. Not too many. Mostly integration (2017)
Yes, I do exactly the same to make sure the output stays the same. Snapshotting is awesome (for go, cupaloy works quite well [1] - jest for react is great) but does not give me the chance to 'record' the underlying logic dynamics. That's why I think unit tests are still an important tool at hand.

donjoe··on Write tests. Not too many. Mostly integration (2017)
I always see unit tests as a snapshot of dynamic behavior by 'recording' the tested logic. I make sure I'm aware of any logic changes since that change could eventually break the desired result.

Whenever I'm vetting in-/output values to a given set of parameters, I do move from white box (unit tests) to grey box testing.

When I'm done with grey/white box tests, I do make sure integration works as expected.

Why all the hustle of moving through 'the onion'? I wanna make sure to detect misbehaving/unexpected logic as quickly as possible. Searching for malfunction detected while running integration tests takes way more time than already catching them at the onion's most inner layer (unit tests).

donjoe··on Ibuprofen alters human testicular physiology to produce compensated hypogonadism
Better check with the doc first. Otherwise you'll produce expensive piss with no effect. All vitamins I bought outside the pharmacy didn't work for me so better try to go with the 'real' but more expensive stuff prescribed by a doc.

Edit: I got Sanomit q10 and Ankermann B12 (1000ug).

donjoe··on Ibuprofen alters human testicular physiology to produce compensated hypogonadism
Just as a side hint: did you ever get your vitamin levels checked? I had migraines with aura a couple of times a week until I got a full vitamine check up on B vitamines and Q10. I had a huge lack of B12 plus Q10. I managed to compensate with supplements (the expensive ones from the pharmacy) and didn't have migraine now in 3 months. Might be worth looking into :)

donjoe··on Kelly Slater’s Shock Wave
They already built one in Thalkirchen:

https://youtu.be/MFHYffdBNmI

As far as I know they're involved in several projects researching locations for new waves.

donjoe··on Kelly Slater’s Shock Wave
As mentioned before, there is a company found by some locals doing exactly that:

http://riverwaveproject.com/

donjoe··on Kelly Slater’s Shock Wave
Yeah, there is some risk. It's not the concrete on the side though but some rough rocks on the bottom which can be quite nasty... That's why locals refer beginners to the second wave in Munich which is located in Thalkirchen.

Some of the local surfers actually found a company which is constructing river waves based on simulation:

donjoe··on Kelly Slater’s Shock Wave
... one of the reasons I moved back :) glad u liked it!
donjoe··on Kelly Slater’s Shock Wave
As a river surfer surfing in Munich I'd love to see our river wave replicated more often. Rivers float 'for free' anyway. Why not just use its power whenever possible and reasonable?

donjoe··on JIRA is an antipattern
Building a city/neighborhood is a really bad example for an agile development tool: agile development is to be used in case requirements are not yet fully available.

In other words, the team is searching for the right and best solution to solve a problem.

In the author's example, the city is already fully planned and ready to be build, thus the solution to solve an existing problem already exists. Why to use agile?

Building a city/neighborhood is a perfect example for a waterfall implementation strategy which can be perfectly modeled with other tools.

As always - use the right tool for the right job and you'll be alright ;)

donjoe··on “I didn’t meet my girlfriend until 12 years after our daughter was born”
I'd love to see the whole movie! It seems like they're looking for funding?
donjoe··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
As an alternative, https://momondo.com works quite nicely for me most of the times.
donjoe··on Ask HN: Is there a better way to document complex software architectures?
To add to this: I highly recommend reading into INCOSE's standards and recommendations on SysML.

Start by going through one of their last talks: https://sdincose.org/rsvpmaker/state-of-sysml-2018-09-12/

donjoe··on Strato Pi – An Industrial Raspberry Pi
... just wait for the first dude sniffing in active mode by forgetting to set the passive flag. The can controller will then not actively compose messages but will set the ACK bit... God knows what might happen by a third party ACK'ing on the bus ;)
donjoe··on How my sexual health searches ended up in the hands of big tech companies
Last week, I got hit by a car while riding my bicycle. You won't believe in how many colors an upper arm can shine. Anyhow, I took a picture of the arm, shared it to a friend on WhatsApp and promptly got a newsletter from Pinterest promoting tattoo posts. I do not have the Pinterest app on my phone, barely use it otherwise and would never search for tattoos since I'm just not interested.

I've been trying to find out since then where and how Pinterest might have gotten my blue/red/yellow/green arm picture from to analyze it, interpret it and link it to my account. They might be able to search my friend's phone's pictures (in case he's got the app which I'm not sure) and link the picture back to my account. Spooky though.

donjoe··on The Turk
The German verb 'etwas türken' (~ to fake sth.) originates from The Turk mentioned in the article.

donjoe··on Ask HN: Cheap places to live with a good intellectual atmosphere?
Just to add my bit here: - Public smoking in public indoor places is completely banned in Bavaria, including pubs, restaurants and bars.

- No one will forbid you to buy your own dryer in case you're not happy with hanging your clothes on clotheslines. We do have a dedicated clotheslines room in our building thus I never needed a dryer myself (and my clothes are getting dry within 2 days even in the winter)

- ACs are recently getting popular in offices, they're rare in private homes due to too less days we'd have to use them. I thought it was odd what I experienced when working in the States: cooling to 16C in the summer months whereas my colleagues would heat up to 22C in the winter months. I prefer sweating over getting a cold in the summer ;)

- Driver's licenses are valid for a life time and don't need renewal every now and then. We are not allowed to drive with our parents before we do the test. If you're an experienced driver, your (European) driver's license will cost you below the above mentioned # since the price depends on how many driving lessons you will need to do.

- Store closure times depends on which part of the country you live in. Berlin is quite liberal with opening hours whereas the south (especially Bavaria) is quite strict. You get used to it and learn to organize yourself better.

I currently live in Munich which offers a lot of cultural and technical inputs. Meetups are happening frequently and the community is quite active. Housing is quite expensive (if you're in an urgent need for a place to stay) but you can still find affordable housing if you look long enough. Salary when working for local companies is way above the German average.

donjoe··on Old Concept Cars
I'd say it looks like an Isetta with a massive glass front:

donjoe··on How the Dutch created a casual biking culture
And no one ever drove you off your bike in Munich yet? Lucky you!

I use my bike every day and I don't mind the winter either. I still can count the times I've been hit. Near misses though happen almost daily. Especially with cars turning right not watching bike lanes.

Good luck and keep on cycling!

donjoe··on Italy bridge: Genoa motorway collapse kills at least 22
There is a live stream from the bridge currently available on youtube:

donjoe··on First drug to prevent chronic migraines approved by EU
Almost the same with me. The neurologist did a blood test which showed a huge lack of vitamin B12 and Q10. High doses of both made a huge difference -> I feel way more fit and awake. The last time I had migraine was about 2 months ago. I'd get it up to 3 times a week previously. Plus while trying to find out the cause for my migraines I encountered coffee to be a trigger. I stopped consuming caffeine in general as well.
donjoe··on How does Hammacher Schlemmer survive in the age of Amazon?
Ey! I always thought Hammacher and Schlemmer only existed as characters of Beerfest...
donjoe··on Show HN: Instagram-scraper – Scrape instagram photos by tags, without API
... indeed. Isn't the script 'under the hood' calling the API anyways (looking at 'scrolldown' here)?

I reversed engineered the API myself a couple of weeks ago which was great fun - especially figuring out Instagram's rate limits on interactions such as comments and likes per day/hr.

donjoe··on Make your own sourdough
My mom's been baking sourdough bread once a week since I can remember. We've been a family of 6 killing at least a whole leaf a day. The awesome thing about sourdough bread compared to yeast or yeast/sourdough based mixtures is the ability to stay fresh for way longer. The neighbors would show up and ask for a piece of the mother dough for their occasional bread-baking experiments. While studying I really missed 'proper' bread - especially during my time living abroad. I've been baking my own bread ever since, too :)
donjoe··on Ask HN: Examples of great landing pages?
dribbble.com comes with really lovely designs. You'll have to look for something fitting your product though...
