n1000··on Passivhaus Detailing and Design
That is not quite true. The relative share of the life-cycle impact of material increases, because total impact decreases. There are a couple of reviews that discuss this matter and normally find that total life-cycle impact is consistently lower. https://www.sciencedirect.com/science/article/pii/S036013231...
n1000··on Passivhaus Detailing and Design
Given that we should be carbon neutral in 30 years from now (2050) in order to have a shot at the 1.5° C target and given that average building lifetime is >30 years, it would be irresponsible to build anything else than a passive house or a zero energy building today.
n1000··on Passivhaus Detailing and Design
The dryness problem normally only occurs if the air change rate is higher than the recommended 0.3. In large buildings this requires rather sophisticated ventilation systems. There are also heat exchangers that recover humidity.
n1000··on Passivhaus Detailing and Design
Many governments, such as the EU have decided Zero Energy Buildings as a target for 2020. Those are basically passive houses with PV systems. Hence they produce the same amount or a surplus of energy as is being used throughout the year.

Thermal insulation helps to decouple indoor climate from the outdoor climate. It depends a bit on what kind of heat period you consider. When high ambient temperatures occur it will remain cool for longer indoor and night ventilation can be used to cool the house. The cold produced by the AC is also better trapped inside, ie used more effectively. There has been a case of extended power outage in Germany due to heavy snowfall. I saw a report that showed how the indoor temperature remained almost constant for the first two days of the outage.
n1000··on Passivhaus Detailing and Design
That is simply wrong. The passive house standard requires ventilation systems with highly efficient heat exchangers. This makes for good air quality. The massive thermal insulation ensures that no condensation occurs in the interior, i.e. no mold problems. A common problem, however (esp. if inexperienced planners design the house) is too dry indoor climate in winter. This happens if air change rates are too high and no humidity is recovered.
n1000··on Apple iOS 13.1 Personal automation via Shortcuts
Oh. This is fantastic. Thank you so much!

For anyone else having issues allowing untrusted shortcuts. The toggle in the settings only appears after running any shortcut for the first time. This is an iOS bug apparently.

n1000··on Tethered Jailbreaks Are Back
With roughly 1 billion iOS devices in use that might be an expensive recall.
n1000··on Apple iOS 13.1 Personal automation via Shortcuts
Will this finally allow me to switch WiFi and Bluetooth off (instead of just disconnect for 24h) from the control centre?
n1000··on Swiss Copyright Law: Downloading Stays Legal, No Site Blocking
Yes, but Swiss ISPs are not allowed to share their client's data as far as I know. So there is no way to prosecute. As I said in my other comment, I know people that received the copyright claim letters from foreign institutions "for information" from their ISP.
n1000··on Swiss Copyright Law: Downloading Stays Legal, No Site Blocking
Hmm. Maybe I am overlooking something here, but my understanding was that an important loophole in the (now) past legislation was the fact that ISPs were not allowed to pass on the identity of their customers even when they were uploading / torrenting copyrighted material. I know a bunch of people that received letters from their ISP saying that they received a takedown notice but did not comply. Maybe that will be addressed later:

> On the hosting and liability front, there will be changes, but at this early stage, it’s unclear how that will play out on the ground.

n1000··on The Man in Seat Sixty-One
For people travelling in Europe: The German railway company Deutsche Bahn has the most complete set of international train schedules in their system. This makes it a great resource to search for international connections. Once I even saw Hungarian railway employees use www.bahn.de to look up their own connections.

n1000··on Using Deep Learning to Inform Differential Diagnoses of Skin Diseases
Unfortunately not. But I remember there was some really weird stuff in there. Anything from minerals to insect skins. It is customised to whatever the diagnosis is.
n1000··on Using Deep Learning to Inform Differential Diagnoses of Skin Diseases
I recommend you try Traditional Chinese Medicine (TCM). I had to drink the ugliest medicinal tea imaginable for a while, but after that my skin problems had miraculously disappeared.
n1000··on Using Deep Learning to Inform Differential Diagnoses of Skin Diseases
In my opinion we have a long way to go before we actually understand many many of the skin diseases. Dermatologists appear to me as the most clueless doctors out there. Their only weapons seem to be cortisol and biopsies. Maybe I was also just unlucky.
n1000··on Berlin crash prompts calls to ban SUVs from German cities
Exactly. My point is about the double standard we face in our society. In public places we sometimes see over the top health & safety regulations but other potential dangers are being quietly accepted. I am not arguing for more regulation.
n1000··on Berlin crash prompts calls to ban SUVs from German cities
Recently I visited a historical hydro power plant, which is still operational. The operators were in the process of adding huge shields and fences around the flywheels due to safety regulations to protect visitors. Apparently they had been only fenced off by a rope and the faith in humans‘ self preservation instinct for the last 100 years. However, when i saw those fences, it struck me as very odd why this is not mandatory on every road. The amount if kinetic energy of those flywheels is certainly comparable to a 1-2 ton car moving at 30+ km/h.

n1000··on Upcoming Firefox update will decrease power usage on macOS by up to three times
Yes – did not find a decent (up-to-date) adblocker yet.
n1000··on Upcoming Firefox update will decrease power usage on macOS by up to three times
I’d assume so, because activating the secondary GPU means a lot more power consumption and is therefore avoided anyway.
n1000··on Upcoming Firefox update will decrease power usage on macOS by up to three times
I am not a huge fan of Safari, but it seems so much more optimised for macOS that it has become my default regardless. I mean an hour extra battery life is really nice.
n1000··on Dual AMD EPYC 7742 Crushes Quad Intel Xeon 8180M's in Geekbench 4
I wouldn’t be surprised if they want to win back market-shares for a few years before choosing less competitive pricing.
n1000··on Bugatti has broken the 300mph barrier
These fancy supercars come with "launch control". A mechanism that will rev in a high range (charging the turbos) and then release the clutch with full torque. I wonder if that helps...

n1000··on Dumbdown – A Tree Language that compiles to HTML
Markdown remains the best hybrid for me, because it strikes the perfect balance between a. formal enough to use pandoc and make htmls, doxc, etc with it and b. still fully human readable, which allows me to take all my meeting minutes with it and be able to quickly copy & paste them into an email or store them on our project share and nobody will really wonder.
n1000··on I find journaling indispensable
It also a very effective technique to reduce anxiety and very useful for people with ADHD. This is one of my 3 goto methods when in distress: write for 30 minutes, go for a run, or meditate.

Great link. Thank you. I fully agree with rule 5, which puts this article in a different perspective.
n1000··on Apple Accidentally Unpatches Vulnerability, Leading to New iOS 12.4 Jailbreak
> Seems a bit overblown when there's a review process in place. I'm sure it's not infallible, but still..

Well, until now I assumed Apple would test for patched vulnerabilities in new iOS releases too.

n1000··on What you may have heard about the dispute between UC and Elsevier
I was wondering too. The librarian that told me about it, is a copyright expert and was outraged. However, it seems like there was not much they could do. I am guessing the fact that this is happening at an Ivy league university means that lawyers are not useful in this matter. They also said that only Elsevier does that.
n1000··on What you may have heard about the dispute between UC and Elsevier
Another fun fact about Elsevier: In their contract with university libraries they exclude the right of fair use as described in the US copyright law. That means one can download papers, but technically mustn't use the data found in them without consent. This is just ridiculous.
n1000··on The Risk of Weak Online Banking Passwords
I often wonder why not all websites (especially delicate ones like ebanking) do not show the number of failed login attempts since last successful login.

That would raise awareness with users (ok, maybe scare some people) and give me some hints that my account may be under attack...
