Mechanical engineering PhD student here. I'm skeptical that there's a shortage of the engineers needed for this.

I know someone who interviewed at a major jet engine manufacturer. I don't know if he would have got the job or not, but he had no interest in working there after the interview. From what he described the place seemed to be a hybrid of the worst of academia and corporations. Publish or perish, poor job security, bad location, etc. I don't recall what the pay was, but I don't think it was spectacular. I won't be applying there when I graduate. If they really needed more engineers, I think they would be making the place more attractive to work at.

Some representatives of the company visited our research group once after the person I mentioned graduated. I didn't get the impression that the company was short of people in their jet engines division aside from one area they mentioned (and there's no shortage of qualified people in that area at my university). Plus, one of the people who was doing the interview actually said they (partially) transfered out of the jet engines division. I got the impression the jet engines division was downsizing overall.

Also, assuming that required knowledge is not public, not documenting important internal developments is a bad practice. I doubt jet engine manufacturers make this mistake. The company representatives, as I recall, seemed to want someone working specifically in the area they were looking to hire, but they didn't seem to need someone who was familiar with the exact methods or materials they used. Learning on the job is probably part of the job description.
Neutral theory is controversial in that it is unproven (or was when I last read about it 6 years ago). It is still a legitimate topic of research.
Great article. Sleep is important. I liked that the article went out of its way to dispel several of the "but four hours is fine" myths. Two of my favorites:

>some people are short sleepers: You can do a test to find out if you have genetic makeup that makes you a short sleeper. That’s rare, though, so by and large, people are not getting enough sleep.

Blunt and effective. The outliers who really do fine with just a few hours are just that: outliers. Congratulations if you're one of them, but your genetic gift doesn't make the need for sleep any less real for the rest of us, and talk about these outliers is mostly a distraction.

>I normally get around six to seven hours of sleep a night and feel fine. But is that just because how I feel has become my normal operating mode, and I could really be functioning at a higher level?

>Right. That’s like the fish and the fish bowl phenomenon: The fish doesn’t know that he’s in the fishbowl, nonetheless that he’s in water. Also, when you’re sleep deprived, research has shown that you’re really bad at being able to tell that you’re sleep deprived.

To me that's a great analogy. Most people can grasp the concept of having a problem and dealing/coping/adapting so long that they don't realize they have the problem. It makes sense that this phenomenon can apply to sleep as well.

Intellectually, I know I need to consistently sleep longer. If only knowing that and then acting on it were an easier gap to bridge (as I write this just past midnight...).
I'd really recommend taking a dive into flutter. It's leaps and bounds better than working with React Native IMO.

Treating Dart and Flutter as one 'SDK/Language for Apps' made it a lot easier to avoid the uncanny valley effect I had with react native vs normal react.
Hi Marky_Nolan.
You Did a great job in Informative rich, yet productive website with the Minimalist design. Kudos. Will share on Facebook group dealing in Cyrto.
Yeah, me either. I was really excited about this a couple years ago, and in the last six months this has actually come back in line with stuff I need. Excited to try it out again.
High salt diets == Hypertension and High fat == heart disease are two "scientific truths" that have been propagated for decades and have turned up as bad science.

I've heard the argument of "all the scientists believe this, so you must be wrong" so many times with these and it turned out I was right. I believe the same will go for other incidents of bad science that most people believe these days.
Most of the last mile is copper, because population density is thin. But in the cities fibre is being rolled out (goal is 87% by 2022).

Crown Fibre Holdings owns the new fibre network (I think Chorus owns all the copper, not sure) but Chorus manages most of it (by contract); Chorus is a crown partner company, and they are regulated and forbidden from certain activities - they were split off from Telecom, a private company.

I don't know enough about the backbone to usefully comment, except that there are at least 3 fibre networks running along the major road I live near.

For a long time there was only one submarine cable with any serious bandwidth (Southern Cross Cable), but aparently according to Wikipedia a new one to AUS was rolled out in March 2017 and another one to Hawaii this month.

>A professor I collaborate with at Penn State named Orfeu Buxton says that 8.5 hours of sleep is the new eight hours. In order to get a healthy eight hours of sleep, which is the amount that many people need, you need to be in bed for 8.5 hours.

So, the title is misleading. It means you should lie in bed for 8.5 hours in order to actually be asleep for 8 hours.

That said, this article has plenty of good insight and is well-written.

I think we are only beginning to understand the importance of a good night's sleep.

I just recently listened to a fantastic episode of the Kevin Rose podcast featuring sleep scientist Matthew Walker [0], and found it very enlightening.

No, that's just how existence works. Systems that perpetuate themselves are more likely to continue existing. Systems that don't perpetuate themselves stop existing. No intelligence required.
Great episode! I just posted another comment about Matthew Walker on the Kevin Rose podcast. There was definitely overlap with JRE #1109, but some new things, too.

I worked at a small tech company that was bought by a large company. They sent a patent attorney to talk to us. He said to send his office anything that might be patentable. He said that patents for big companies were kind of mutually assured destruction in the sense that if someone sued us over infringing on one of their patents if we had enough patents they were probably infringing one of ours.
Did anyone familir with the literature say "all the scientists believe this"?
>only that I believe it to overwhelmed by a sea of countless other factors that cause someone to succeed or fail at getting into college

Yes it can be and is at an individual level.

If you removed 50 points from every Black student's SAT score just because they were Black, there would still be countless other factors that caused them to succeed for fail at getting into college. Their being Black wouldn't be the largest factor (family income still would be).

But across the entire population, you would see a significant drop in the number of Black students in college.

As to a link: Here's a link and a quote from the abstract of a relevant metastudy

https://www.ncbi.nlm.nih.gov/pubmed/26090843

"The results showed a negative and moderate relationship between dialect use and overall literacy performance (M effect size = -0.33) and for dialect and reading (M effect size = -0.32). For spelling and writing, the relationship was negative and small (M effect size = -0.22). Moderator analyses revealed that socioeconomic status and grade level were not significant predictors for relations among dialect use and literacy skills."
I'm not sure it is fair to call that a wart. Back when JCL was designed, C/C++ didn't exist yet, and nobody used "//" as a comment syntax. (C's predecessor BCPL introduced // comments, but it was designed in 1967, and OS/360 was already shipping to customers in 1966; C itself was designed in 1972, and initially it didn't have // comments; C++ borrowed them from BCPL in the 1980s, and then C borrowed them back from C++ after that.)

A more obvious example of a wart would be how it exposes low-level details of disk layout (e.g. space allocation in cylinders and tracks), which improved performance and simplified implementation back in the 1960s, but which nowadays is just useless complexity–modern disks have completely different physical layout, and you have to buy expensive mainframe-specific SAN controllers which know how to simulate the ECKD physical layout of legacy mainframe disks on top of modern industry standard disks/SSDs.
It would be much easier to just forge a marriage certificate, they aren't exactly high security documents.

Excellent article. It's so easy to think "same inputs = same outputs" but that's such a simplification. There's so much more in between!
True. There are always consequences. But if you refuse to pay then you learn how to survive all of the threats you mention which is worth the cost. The point is that the vast majority of debts are legally invalid and unenforceable. They are just a con. Whether you chose to be a mark or not is up to you.
Just wow:

Q:
I heard a rumor that Elizabeth Holmes’ deep voice is fake, as in a part of the performance, like not blinking, any truth to that?

Yep, true. Early on someone gave her advice that if she deepened her voice the male dominated business scene would take her more seriously.
Yes. Regular ticket prices for trains are horrible expensive in Germany. You can pay a yearly fee (called Bahncard) to get 25% (62€) or 50% (255€) off. There is also a flatrate for everything called Bahncard 100 (4.270€)

You can also book early. Often you get a ticket for 20-60€ but these are limited. At least they made an UI for this: https://ps.bahn.de/preissuche/preissuche/psc_start.post?dbka...

If you don't use ICE/IC you can get a daily flatrate for 44€ for whole Germany or for 20-25€ for one (or multiple) federal states.

Now we often have empty trains and busses are on the Autobahn...

yep. Health insurance shouldn't be called insurance. It should be called a levy, and all citizens making more than a certain amount have to pay into it, and all healthcare costs paid for by this fund. Insurance companies are middlemen that don't provide real value.
Alternatively: how good is your monitor's colour accuracy?

The reason is that there is a lot of overlap of patients with hypertension and chronic kidney disease. When your kidneys don't filter as well, one of things that your body holds onto is potassium. High potassium levels (among other things) cause cardiac conduction issues and arrhythmias which can be fatal if not intervened on. I.

I believe I'm one of the "short sleepers" they mention in the article. I've bought wirstband mostly to track my sleep patterns. Even though article says that devices like fitbit are not accurate enough in tracking different phases of sleep, my goal was largley to see how much time do I spend sleeping. In the last four months, I average out at 6,1hrs.

90% of the time I will wake up before the alarm and will sleep the same amount of time over the weekends, when I usually don't go to bed as early as I do during the working part of the week. The thing that I constantly think about is - could I benefit from those 2 extra hours to get to that magic number 8? I would really like to try it, but I keep waking up after 6 hrs. :)

I've started to think it's because of not so healthy lifestile - no exerxice, sub optimal diet, irregular bed time. Is it possible that my poor lifestyle results in me waking up after only 6 hrs of sleep and while feeling OK (it became normal to me), I could feel better if I slept longer? That was always something I pondered about. How to know if you really are a short sleeper, or you're just a person that gets by with sleeping less than recommended while not feeling as good as they could if they slept longer?
I used to habitually play bullet and blitz chess online, which confirmed the necessity of sleep for me. After a 6 hour night of sleep I noticed my rating would drop significantly the next day, and after several low sleep nights in a row it would take days to recover completely. A graph of my bullet rating over time clearly showed the periods of low sleep.

Most people don't have a measurement that objective. After I stopped playing chess so much in college, I even caught myself trying to excuse my poor sleep habits by telling myself I wasn't falling asleep in lectures and I could still finish my homework.
Pretty good writeup, as it sheds light on what it was like to work at and tolerate (for a few years) such a poisonous company. Even with all the shady things observed, and the fact that Holmes's ideas and goals were a big sham, the author seems to have been engaged enough in the science to think -- at the time -- that the goals were legit.
Some of this is a tad outdated. For instance, PyTorch has vastly improved their device management APIs in their recent 0.4 release.
Even genuine goods sold by Amazon can be problematic. I bought a consumer-grade router sold by Amazon, and what arrived was an obsolete version that had not been produced for 4 years.

Small quibble: the headline should be "in bed for more than eight hours"

The expert says 8.5 hours in bed (trying to sleep) to sleep 8, since we don't sleep the whole time.

So, if you have an accurate sleep tracker, "8" is still the number.
Lisp operators are distinct from functions. It's just that arithmetic operations are functions; Lisp dialects use operators for various other constructs that cannot follow the function call evaluation rules.

C++ sort of makes operators functions. Any overloaded operator is a function. If a is a class object then a + b can be spelled otherwise as a.operator+(b). This doesn't work for the built-in definitions of the operator, as in 2.operator+(2).

The built-in + operator in C++ can also do things that used to be impossible in C++ until its template system became more powerful. Namely, the result type of the built-in + is deduced from both operands and can be different from both of them. If C++ were being redesigned clean-slate, it would likely be that operator overloading is allowed for the non-class types like int, and all the built-in operators are defined in terms of templates, whose deduction/instantiation reproduces all the rules.
Well, the power of a battery the size of a brick in the 80’s is now available in a AA form factor. I’d say the improvement has been profound, if not quite as profound as Moore’s law is for CPUs.
Also overlaps with JRE and probably the one you linked, but I really liked this Rhonda Patrick podcast with Dan Pardi too.

Good to know. I wonder if that's a recent improvement? Last time I was doing lots of sysadmin work was 2011.
As an American expat living in Munich, I honestly don't know which choice you made. For me the easy choice would have been the train... Large, comfortable seats, room to get up and walk around, no traffic, and no need to focus on driving. You're right, it's not a hard choice.
In most cases, it feels like absolutely nothing.

Above roughly 150 systolic, it can start to manifest as headaches (as others have mentioned), but doesn't always.

In my case, after it had gone undiagnosed long enough (by an incompetent doctor), I had extremely severe headaches, constant nausea and vomiting, and vision problems that turned out to be capillary hemorrhages in my retinas. That was at around 240/120.

BUT: I am extremely lucky to have had all those horrendous symptoms. They alerted me to the severity of the problem, and caused me to escalate to a competent doctor. For many people who get up to that level of blood pressure, the first (and potentially last) symptom is a stroke or a heart attack.
Delightful.

I sleep 6 hours during the week and 10 hours on the weekend. I pretty much only remember my dreams on the weekend. I wonder how much that relates to sleep deprivation. I only lucid dream if I sleep for 10 hours on vacation.

There were a couple of cases where two cells seemed wrong, no matter the order, so I also suspected the monitor is the culprit.

Also, what's the scale? They say lower is better but how better?
Yeah, but that (1) feels like the hardware equivalent of DLC, and (2) the resulting unit is much thicker than it would be if the battery were designed into the device from the start.

I get why some people prefer thinness over battery life. Not all use cases are the same. Just wish that there was an option when choosing a model to go with svelte or chunky.

The bit that really stuck with me from this podcast was how overworked some medical professionals are, especially those in residency. Which ends up contributing to them making mistakes with their patients, including deadly ones. Shift work is already extremely taxing on the human body, on top of the large amounts of stress nurses and doctors are already under; but on top of that, we're working the newbies 80 hours a week!?

According to Matthew Walker, this phenomenon started with one influential guy who thought it was important for the residents to "prove themselves" by working these insane hours, and it's just kind of stuck since then. Scary stuff, and basically no reason for it.
The article understates how important pure darkness is, just a crack of light under a door can whack lab animals' melatonin levels. Also for constant biphasic sleep (which you want) 8.5 hrs isn't really enough, certainly not year 'round (I do skimp a bit during summer, near equinox.)

Do you have any idea how complicated a single turbine blade is? It's a monocrystal of a superalloy that retains strength at over 1.5k degrees F, and it has channels for coolant because it operates beyond that temperature.

I get it, but it really cuts both ways.

Having worked at a firm with largely big-C Conservative, Christian, male heads of department and up, I've seen how my more "out-there" co-workers were treated[0]. Folks who were open about their "pagan" religions, or polyamorous ways, or even women of the same social standings who dared have a job, get pregnant and raise children were treated terribly. If it weren't for the fact that good coders and managers are hard to find, I'm sure it would have been even worse, and them having some protection would make resting easier.

Still, that lack of protection meant they could find greener pastures and leave sooner. Personally, I've had a few jobs wherein I was lied to about the position, duties and responsibilities, etc. and after finding out it was a "Take it or leave it" situation, I left.

I really wish we had a bit more leeway in terms of negotiating employment agreements, so folks could find the right balance for them. Sadly, the business world is full of cargo-cult behavior so we get bog standard take it or leave it deals.
