Basically, the theory is that somebody like Bruce Jenner, actually has the mind of a woman, but born inside the body of a man.

More specifically, the theory is that, a normal man has a male mind inside a male body. A normal woman has a female mind inside a female body. But, somebody like Bruce Jenner, has a female mind inside a male body. The other cases are a male mind inside a female body, and a neutral mind inside a male or female body (aka, agender).

This has huge implications. It means that your mind and body are two separate entities, biologically, and not a single entity. They work together most of the times, but at times, your body will fight your mind, as drug addicts will tell you. The mind wants to be clean, but the body craves the effects of the drugs, the body fights the mind, and eventually, the mind lose, and the body compels you to take the drug.

This also implies that gender is not a social construct, but rather gender is biological. If your mind was born female into a male body, no matter what society teaches you, you will always know that you're female. Deep in yourself, you'll always identified as female, even though your body is male.

Israel (to be exact, the strip along the mediterranean beach where all the offices and IT companies are) is incredibly humid, in fact — that what makes the heat unbearable. But the stories I heard were from California, and I assume it's just as hot over there.
No sterile transit [1]. That's it for me. That's why I will pay extra to get a flight that does not require changing within the US.

Everywhere else [2], if I am on my way from country A to country C and will be changing aircraft in country B, I follow the sign for "International Transfers" and effectively just walk from the gate at which I got off one aircraft to the gate at which I will get on another (an airport in Europe somewhere - can't recall which one - even managed to provide me with sterile transport to another terminal to do this; half the train was isolated by locked doors from the other half, and my side of the platform had different entrances and exits that were already within the security-checked section).

No security checks necessary because I went through them in airport A, no immigration because I'm not entering country B. To force me to go through immigration and then turn around and come back through the entire security theatre again is such a massive waste of everyone's time and resources. So painfully frustrating.

[1] I hear that a handful of US airports can actually manage this, but generally not. I recall having to go through immigration at JFK many years ago purely to be able to walk across the concourse and go back through the system again, just to change plane. What a massive waste of everyone's time and money.

[2] Not quite everywhere else. Of all airports, I had to go back around through some security in Dubai just yesterday. Which is utterly ridiculous, as Dubai airport is a shiny modern airport that is in many other ways very good.
The internet is much more than just HTTP traffic - the purpose isn't to provide access to content so the fact that these are content providers (i.e. data is requested) doesn't matter. I can host my backups via a web server at home and wget them from my remote server, the fact I "requested" that from the remote server means nothing.

The ISPs customers are paying for a connection to the ISPs network, nothing more. Every connection to the network is a node - in a network neutral world the fact they are a content provider is meaningless. If they need to push more data, they need to pay.

I really don't see the difference between this, and a large company attempting to send their backups via the web. We could easily set it up so the remote servers are "requesting" that data -- but it's not the cable subscriber's job to subsidize my network infrastructure so we lease a line to ensure the speed we need. We have over 100mbps connection on both sides, but that is only a 100mbps connection to the ISP. If we need to move data at that speed all the way from point A to B, then we need to pay for the infrastructure to do that.
I would like to mention that Coq is also used to extract _verified implementations_ rather than model checking abstract algorithm design (as in TLA+). This property might be very desirable depending on situation. As for me this property looks very appealing.

Yesterday, I spent some hours exporting my roughly 45.000 photos in my iPhoto library to a folder structure sorted by year and event. The tool I used is called Phoshare (https://code.google.com/p/phoshare/). The site says its no longer supported, but even with the latest OSX and iPhoto versions it seems to do the trick. I was able to convert faces to exif meta tags containing the persons name. Otherwise I did not have a lot of metadata in iPhoto. Now I'm heading over to digiKam or maybe some other tool outside the walled garden.

For my iTunes library, I first used beets (http://beets.radbox.org/) to fix the metadata of my music files, and now cmus (https://cmus.github.io/) as a music player. As an alternative music player I'm considering EMMS (https://www.gnu.org/software/emms/).

I don't know about alternatives to iPhone syncing. My iPhone died last week, and I'm waiting for my Fairphone to arrive in a couple of weeks.

To put this in perspective, 30mA costs about $0.15 / year at typical US electric prices. 500mA is $2.50. A tiny draw regardless, but probably a lot more significant if you're running on batteries.
The chmod gotcha that I hit occasionally when I haven't used the chmod command for a while is the difference between "chmod -R <perm> <dir>" which recurses as would be expected and "chmod -r <perm> <dir>" which interprets "-r" as the <perm> spec, complains that the file <perm> doesn't exist, then removes read permission from <dir>.

This feels like a terrible idea.
This distinction is disingenious (edit: I probably mean spurious).

The number of people in industry who use either tool is incredibly small and is likely to remain so; developers spend 20-50% of their time on test suites and STILL don't feel it's cost-effective to write down formal specs, even in TLA+-style specifications.

What matters is that important libraries and frameworks can be verified, not that everyone and his brother can use formal methods for every WordPress website they churn out.

> To say that type-theoretic theorem provers (or the Coq system specifically) are merely academic toys compared to TLA+ is disingenious.

I never said that Coq is an academic toy. Some projects done in academia and used in the industry have been verified with Coq, but I am not aware of actual (direct) use of Coq in the industry (but would be interested to learn of any).

> I'm not sure I understand why "Computer Science-type math" is an unreasonable foundations for a program specification tool, which is what TLA+ is

I've never said it is unreasonable, only that it is foreign to most engineers (as well as most academic CS people), or rather, more foreign than basic logic/set theory.

I would say again that if you're comfortable with type theory, you might enjoy Coq better. If not, TLA+ would probably be more approachable. TLA+ has the added advantage of having a model checker, which is very useful when you don't have the resources required for a full proof, but still want a good confidence in the correctness of your algorithm.

> A formalization of the C standard is a HUGE undertaking, independent of what tool was used. Let's celebrate that achievement!

Oh, absolutely! It's just that stories like this make people interested in formal methods, and Coq, IMO, would be daunting for most. TLA+ is a good entry point to formal methods, even if you later choose to move to dependent-type approaches and tools.
I can get up early and do things, but I feel best when going to bed at 2-3am and getting up at 10-11am. By "natural" cycle I meant that if woken up without an alarm clock and go to bed when feeling sleepy (i.e. during lazy holidays) I tent to align to the mentioned hours.

Has there been any scientific evidence suggesting this is the case?

Can't find it after quick googling, but I've read about a study which claims that there are no such things as "night owl persons", but it didn't convince me as it was talking about extreme cases as staying up all night long and sleep during the whole day.

nice to see them respond and even address some of the issues. i know security is a big craze right now, so it seems insane people would put systems online without any real meaningful controls, but the reality is until recently, most went untested and were viewed as unnecessary (https everywhere? n are you crazy? https is expensive!).

i think its only in the wake of these big public disclosures, and the reduction in cost for controls that people are taking notice. the problem is, we have decades upon decades of very immature software out there, and very little economic incentive to pre-emptively secure them. depending on the information they host, it may simply never be fiscally sound to properly secure them.
>The only competitive strategy that seems to be working at the moment is having a vertical that is sufficiently different from the incumbent that you can attract existing users of the incumbent's network to use yours in parallel.

How is this any different than Coke building up a trusted brand over 100 years? If you want to compete in the drinks market, you need to find a different vertical (sports, energy, fruit, health, etc.) and build up your own trusted brand.

I think we'll see the government slowly coming around to endorse/oversee/standardize digital trust networks as they always have through the FTC, FDA, FCC, etc. They've already started with Title II of HIPAA in an attempt to regulate how data flows in the healthcare system so that patients can trust healthcare providers.

But do we really need to oversee/nationalize a social network/content aggregator such as Linkedin or Facebook?

> The number of people in industry who use either tool is incredibly small and is likely to remain so

I agree, but I see some chance of TLA+ of getting wide(r) adoption, precisely because it is rather easy to learn and uses math that most engineers are already familiar with. Also, it allows gradual verification: specification -> model-checking -> proof (with each additional step being completely optional)

> not that everyone and his brother can use formal methods for every WordPress website they churn out.

I don't know about WordPress websites, but Amazon engineers do use TLA+ to specify many (most?) AWS services.

Assembly and C are dead simple compared to Java. The C reference manual is about 200 pages, if I dropped the Java reference manual(s) from a building it would create a sizeable crater.

Assembler is simple like lego is simple: the basics are tremendously easy to understand but the distance between the basic elements and the problems you're trying to solve is very large.

The more 'batteries included' something is the more time you'll spend learning about the eco-system and less about the language per-se.
This is probably some kind of testing artifact. Table 1 shows that 64.3% of monolinguals were literate compared to 92.9% of bilinguals. Then in the supplemental methods we see that illiterates took a different test than literates. They defined cognitive impairment as a score of under mean - 2*SD measured from groups consisting of ~80% literates:

>"The process of adaptation included culturally appropriate modifications of the original English version of ACE-R by examining each item for cultural relevance, translatability, comparable difficulty and adaptability with an aim of tapping the domain identical to the original version. Translations and back translations, and pilot testing were done based on standard procedures.3 ACE-R was adapted for the illiterate population by modifying literacy dependent items.4

Normative data and cut off values in the local languages- Telugu and Hindi were developed by administering the test to healthy controls. Telugu control group subjects consisted 907 literates and 199 illiterates, and Hindi control group subjects consisted 436 literates and 109 illiterates. Mean and SD for total scores and sub-scores in each domain were calculated across 4 age groups (20-39, 40-59, 60-79, 80 and above), and three education levels (>12 years, 4-12 years, 0-3 years), using standard formulae of Mean-2SD. Impairment in cognition was defined if the score on the ACE-R sub-domains was less than 2.00 SD below the mean level of age and education-matched norms."

Then we have the arbitrary age groups and education levels which makes this look p-hacked, there needs to be some assessment of how much those arbitrary choices affect the conclusions.

MOBILE APP DESIGN TRENDS FOR 2016
Tri Alpha, General Fusion, and Helion just got major coverage in the NYTimes and Time Magazine. Here's a summary: http://nextbigfuture.com/2015/10/pictures-of-tri-alpha-energ...

Tri Alpha has achieved stable plasma, next step is to ramp up the temperature, which is relatively easy. According to their model the plasma should get more stable, in which case they'll move straight to an attempt at net power from aneutronic boron fusion.

Helion and General Fusion haven't released any major results but they seem to be doing well, and have good funding. Helion is attempting a mostly-aneutronic hybrid D-D/D-He3 reaction, which I think is news since four years ago.

EMC2 released a paper about a year ago: http://www.nbcnews.com/science/science-news/low-cost-fusion-...

They're looking for funding, and need about $100 million for the next step: http://nextbigfuture.com/2015/01/emc2-chief-scientist-presen...

LPP is doing a lot better with funding since their indiegogo campaign, and is working on getting the last residue of contamination out of their reactor chamber: http://nextbigfuture.com/2015/10/lpp-fusion-will-line-vacuum...

Some recent work suggest that petawatt picosecond lasers could ignite boron fusion: http://nextbigfuture.com/2015/11/picosecond-pulsed-laser-des...

The most advanced lasers have been increasing by a factor of 1000 every ten years: http://nextbigfuture.com/2015/11/generating-kilotesla-magnet...

Sandia's MagLIF got good results in 2014 and is making upgrades: https://en.wikipedia.org/wiki/Magnetized_Liner_Inertial_Fusi...

Germany's about to turn on their stellarator. UW's Dynomak and MIT's ARC are looking for funding.

Edit: also see this IEEE Spectrum article on ARC, LPP, and fast lasers: http://spectrum.ieee.org/energy/nuclear/three-alternative-fu...

And Scientific American has a new article covering at least one fusion company I hadn't heard of, but I don't have a full text link: http://www.scientificamerican.com/article/why-fusion-researc...

Also of course Lockheed Martin's made a splash in the press, but they haven't released much detail and fusion researchers have been fairly skeptical.

Big risk rejected? As far as I see it (German, but not from Hamburg), the concepts weren't very convincing. E.g. the promise that it would only cost Hamburg 1.2 billion € and that the federal state would pay the remaining 6.8 billion. Which is nice, but they didn't actually manage to get the federal state to agree to that, much less to covering any extra-costs. Or unfinished plans for reuse of the built infrastructure. Add general mistrust against the IOC and you get a result like this, even after a massive pro-olympia advertising campaign.
It's unethical to inflict "needlessly hard" technologies on a client who isn't using them already. But an enormous fraction of the world's valuable, productive software is both needlessly complex and built using (arguably) obsolete tools and frameworks.

The are good career reasons to think long and hard before specializing in this stuff. After all, once you go too far down the rabbit hole, you may not be able to climb back out, and nobody wants to be a 35-year-old developer with a completely obsolete skill set.

But if you're a 55-year-old consultant, you may be planning to retire long before the systems you're working on disappear. In this case, I can't see anything wrong with specializing in ugly, valuable dinosaurs that nobody else wants to get near. Under the right circumstances, I've heard of this work paying $350/hour and up.
Outside of DBs, indexes have shown themselves to be extremely useful in string problems in bioinformatics (my area of research). The modern workhorses of this trend are the Burrows Wheeler transform + FM index (together) and Bloom filters (also mentioned in the link). These have been applied to sequence alignment, de novo assembly of genomes, and compression of sequences. I posit the same bag of tricks can be applied in the NLP/machine learning settings, but I know less about how commonly they have been.

There's a good set of notes touching on this stuff here: http://www.langmead-lab.org/teaching-materials/
