You mention you bought a wristband. Tracking my sleep is one of those things I want to start doing. Do you have any recommendations?

I don't particularly want to remember to put it on every night. I know Nokia launched a mattress pad recently (https://health.nokia.com/gr/en/sleep) but I'm concerned about how reliable this is if I don't sleep exactly on top of it. (Plus I don't know how this could actually tell anything like sleep cycles and what not, or even detect that I'm asleep vs. watching TV in bed)

Itsy probably a valuable adaptation tool. When my son was born in went from 8-9 a night to 4-5 for a few months. At a certain point it started feeling like I adapted. I wasn't really miserable. I wasn't dragging myself through the day anymore.

Then when my sleep went back up as my son got older, I had that moment of, "holy crap I forgot what rested felt like. This is amazing. I actually want to go for a pointless walk!"

I thought train systems were heavily subsidized by the state across Europe. Why are tickets so expensive? The distance isn't far at all, by American standards I'd expect to pay roughly $20-30 for a train ticket across that distance. 150 EUR you should be able to fly for that price.

Theranos may have been outright fraud but their technical claims never seemed that outlandish. There are many legitimate companies/academic labs working on similar bloodtests and even brining more limited versions to market.

There timing was excellent too. I actually remember thinking a few years ago that all one would need to do to design something like the theranos product is run enough blood samples through a good mass spec and load the date into map reduce. But based on research since then "enough" turns out to be a whole lot.

And there are also scientists who think that ideas like that are ridiculous and biomarkers for certain diseases (like early stage cancer) will never be findable in blood. And many of them are vocal about the fact. But since there are experts on both sides that isn't a clear indictment of the idea.

It is also worth noting that the "crisis of reproducibility" is bad enough in bio that I wouldn't haven been surprised if Theranos had very promising early results that didn't pan out. Thats happened to a lot of people.

Personally I fully believe we'll see a Theranos like product in the next 20 years around the time protein sequencing and mass spectrometry tech gets cheap enough to do studies with on ~millions of people instead of ~thousands.
They had a "High Speed" line before, but it was on old tracks, and they had to use tilting trains. I took it a few times when I lived in Berlin. It was somewhat slower than driving. Still, the ICE is an excellent train. It's very punctual (Germans will complain when it's five minutes late), it's smooth, it's clean, the seats are comfortable, you can get a seat with a table if you want, there are power outlets, and if you get hungry, you can go get a snack, a beer, or a full dinner. It's just just a civilized, pleasant way to travel. The Internet, either through the DB system, or my normal 3G/4G tethering was a bit spotty, but I was nearly as productive on the train as I would have been at the office. At six hours Berlin-Munich, it was much nicer, less stressful, and more productive en-route than an airplane, but somewhat slower. At four hours, the train is a no-brainer.

Air travel is the king of hidden time fees. They say that it's an hour from Berlin to Munich, but you have to show up at the airport an hour before the flight, it takes 15 minutes to get off the plane and get out to the curb, even if you didn't check a bag, it takes 40 minutes to get to the airport, and another 40 minutes to get from the airport to the city center. By the time you add it all up, 4 hours is how long it takes on the plane, and most of that is annoying stressful walking from one place to another, waiting in one line after another, cooped up in a tiny seat, and for maybe 30 minutes of the whole 4 hours, you can use your laptop and do something useful.

Depends on how they're defining leadership in TFA, as it is vaguely written such that it could mean managers or it could mean technical-leaders, e.g. a team lead / tech lead type.

If I have an idea that I know is correct / am sure of, I would broach it with the concerned folks. If I couldn't get them onboard, and was still sure I was right, I would discuss it with the senior engineers to get the feedback. If, at that point, I was still sure the idea was right I would try to once again try to convince the team of the merits, with the available appeal to authority.

At that point you either win, give up, or try to convince management to enforce the idea.
Not only that, but (speaking from personal, anecdotal experience), most of the benefit as it applies to work tasks will be realized over time, for outcomes where consistent and sustained focus and stress management is most beneficial.

That being said, what the mindfulness movement tends to gloss over is the fact that, with enough determination, meditators will occasionally shake loose deep-seated mental gunk, resulting in better quality of life if processed, but sometimes with a tumultuous period while dealing with it. Naturally, performance in other areas of life might drop during such a period.

There are certainly consequences, but my point was some people have established they don't care about consequences.

If there is one thing in this world I'd like to see, it's the worker's right for an afternoon nap: I really would become highly anxious if deprived long-term of my siesta.

I've been lucky in most of my environments to find somewhere to close my eyes and sleep for 10-15 minutes - I just need somewhere to lie down or recline and something to block the light: if I'm tired enough sound doesn't bother me. Some people tell me they just don't fall asleep quickly enough and don't bother to take any time to rest, so it's good to see the scientist here mention quiet-time and meditation as options.
Cheap (and even not-so-cheap) LCDs can be pretty inaccurate:

https://en.wikipedia.org/wiki/Farnsworth-Munsell_100_hue_tes...

In particular, I suspect the DACs and gamma buffers used to derive the LCD driving voltages may have some non-monotonic effects, which would definitely affect the test --- i.e. if increasing the numerical R, G, or B value actually decreases the corresponding colour intensity, even slightly, of the light emitted.
I'm curious what you'd be looking for in time spent. It seems to me that it's just a true or false. I personally did it intermittently while I was gaming on my other monitor. If anything, I'd say adding a confidence weighting on each color scale would gather more data.

I do certain charitable things but I don't discuss it except with a few people who also participate.

I interviewed with a company here in Austin early this year and one of the things that bugged me was how they'd turned their charitable work into a marketing tool with slick brochures. I actually felt bad about being more interested in the actual business work than the charity work.
Hands down, it's D's shorthand array operations.

int[] a = [1, 2, 3];
int[] b = a[] * 3;
assert(b == [3, 6, 9]);

a[] += 2;
assert(a == [3, 4, 5]);

int[] c = a[] + b[];
assert(c == [6, 10, 14]);

This of course works with D's slicing syntax so you can do stuff like a[0..1] *= 3.

Not the parent, but I've been using the Oura ring (https://ouraring.com/) for almost a year and it works very well for sleep tracking. It's a sleep tracker above all, and has rather limited exercise tracking. It tracks resting heart rate, sleep phases, body temperature, and breathing. There's also an API to download data from their cloud service, although I haven't tried it.

I haven't yet received the newer model, but it seems to solve the issue of limited battery life in the previous model and the ring is also significantly smaller.
Your people shouldn't be doing manual config regardless of if you're on-prem or cloud. If they are, you're going to have a tough transition to cloud, and you're still going to need a lot more of those people than you think you will.

I have to concur with this 100%, most true crime shows from Netflix have felt padded, something where I feel like if the podcast Criminal can make an enthralling episode about an event, the TV versions should be adding a lot more for the 10 hour version. In fact, the only "true crime" series I can think of actually completing is American Vandal, which was not only engaging but laugh out loud hilarious as it mocked itself. I'm truly curious to see if they can capture it in a season 2 without it being a repeat of the same.
Of course, there could be some personal taste and behavioral patterns that endear the audible versions of that format more compelling (I usually listen to podcasts during times when I'm not able to be distracted with a phone, articles and texts, such as when I'm driving, yard work, or walking the dog). It could just be that the format for TV relies far more on imagery and visual cues when produced for the screen.
I do know that I really haven't seen a real true crime TV series keep me engaged beyond an episode or three, which probably just means I fall out of a different "taste cluster", but there are just some shows that can use visual imagery to enhance a non-fictional topic (Vox's Explained comes to mind here). Unless there is a lot of in-depth information, and a way to make it salient to the story, it's hard for me to value the time commitment.

Likewise, even fictional shows with short seasons can feel tedious at times, which for me, many happen to be British shows, though not all (I enjoyed Safe, but got really bored during Collateral and The Fall, both of which I've heard great things, but much of the storylines just ended up feeling as if scenes were there to "enhance the tension", but served some other purpose).
Again maybe super personal and cultural, but I do love long format television, just please give me a reason to keep caring about the outcome without having to wind down some plot rabbit hole).

I might just be impatient and a typical American who is affixed with getting "a hook" somewhere in the first 3 episodes, or I'm probably going to give something else a try.
And there are quite a few really good foreign series that I enjoyed, (such as The Rain and 3%) and then some domestic and international shows that put me in the same taste cluster as shows like Dark, The OA and Sense8 that really just never connect. I'm not sure if that's a padding issue per se, but I guess anything that you're not really getting into just feels tedious after a while.

German/UK/French trains are less subsidized than in the U.S. That is to say, the government subsidizes the capital costs, but not the operating costs. 150 euro is not expensive for that distance. That's almost as long as DC to Boston, which is a $200+ Amtrak ticket (Northeast Regional, not even Acela) during business hours on a weekday.
Sadly, it isn't remotely that good, closer to a change from C to AA. NiCad rechargeables have been around for over a century and LiPo only has a density about 3x higher. Overall we've only increased the energy density of the average rechargeable battery about 5x in a century, with most of the increase from introduction of NIMH then LiPo

Improvements in power efficiency have made battery advancements seem better than they are.

It's difficult. They privatized everything in the early 90ies and even attempted to go to the stock exchange - this resulted in cuts and bad long-term decisions - now most of the Deutsche Bahn is public owned but a private company. They probably want to make some profit where it's possible. They need to invest a lot of money in the coming years because their infrastructure is crumbling and running on attrition.

Here are the prices vs. inflation: https://media0.faz.net/ppmedia/aktuell/wirtschaft/1643856533...

However the price for a certain track depends on a lot of things and this new high-speed track has lot's of buisness customers that avoid a flight this way - so it's priced higher.

It's a complicated system with lot's of subsidies, subcontractors and so on. There is a price to pay for using the track to a different company that runs the train...

Another problem is that freight train traffic is even more expensive and they simply forgot to invest in the system for 30 years - now the Autobahn is clogged with trucks...

Wanting to unionize is something that should come from the bottom up, and in my mind, is usually a sign that there's a serious disconnect between corporate leadership and employees. A few disgruntled employees is not indicative a major problem within a company and if there's no major problem, why form a union?

Salesforce pushing for regulation on their own industry would be seriously harming their customer base, since their a service provider, not a marketing company themselves. If there was to be a call for regulation in an industry, it would be one or two steps removed from SF.

The best thing about trains is that you end up right in the city center, and you can often just walk wherever you need to go.
Its complicated.

Short form: Basic pay is very low, partially justified by all of the living expenses that the military covers for you (food, housing, health care). If you live off-base, you get an extra pot of money, the "basic allowance for housing", BAH.

If you have dependents then your BAH is higher. I definitely knew of couples that had justice-of-the-peace weddings right after they were engaged, and then had a formal ceremony 6-12 months later.

All of the rate schedules are published online. The married/single difference for an E-5 (mid-level enlisted rank) in New London, CT is only $369.

The big difference is that if you are married, then you are more likely to qualify for off-base housing in the first place.

I mean come on, unless you have been living under rock you should know about the Keyboard - Somehow they manage to make a keyboard only be reliable enough for 1 year. And you have to pay insane fees to have it replaced. And they make a fuss about it only fails in less then 5% cases anyway. Um... We expect Keyboard failure to be less then 1% for every manufacture these days. And even more so for Apple. May be even 0.01% or 0.1% after 5 years? There are still lots of people using Mac from 5, 6 or even 7 years ago, how many of them have had keyboard issues ever? That is excluding how the key depth issues and they manage to make the keyboard so loud to deceive its user that it has clicked.

Trackpad - Finally enough people are coming out and said the amount of false positive on its extremely large trackpad is driving them insane. Yes, even 1% false positive is crap. You don't want to have your trackpad disrupt your workflow few times a day when you are typing.

There was a comment below about people are using 5-6 years ago hardware because it is good enough and hardware update are no longer important. That is like so far from truth.

These people wanted an upgrade, but there is absolutely nothing in the product line they could upgrade into. You bought a Mac mini and want something faster, may be with SSD at least? No, not unless you move to iMac. I mean heck even iMac still ships with HDD in 2018. MacBook Air upgrade without the crappy keyboard, the current Air doesn't offer any upgrade and its Screen is still crap. A TN FHD screen, doesn't even have to be retina, cost less then $10 more in BOM cost.

We can, in the old days try hard to spin whatever Apple has pumped out are Great in one sense or another. Now they are not, they don't care about it enough. The attention to details is no longer there, and they are still charging a lot for it.
