I'm surprised that shopping centres/malls don't support these sorts of things outside peak hours. When people are dropped back at the end of their day, they could do some last minute shopping, or grab coffee or whatever.
Not sure about the stipend. The PhD is typically 4 years.
Nit: Dunning-Kruger is actually when you're bad but don't realize it. I think you mean "Impostor syndrome," where you're good but feel like an unskilled fraud. :)
I've noticed this is frequently the case for white collar frauds. I don't know if it's because they have so little regard for the law being applicable to them, or if they get a kick just from breaking it, or if we're all we are seeing is the tip of the iceberg (i.e. he's making $300k * 50 vendors), but it's frequently shocking how little profits were made on some crimes that have sent (b/m)illionaires to jail for a long time.
I dunno. mikuszefski's answer is kind of borderline, especially with that shading!
Passenger's users(like me) not know much about app server's technology details, I want to focus on bussiness. I can write article say "Passenger is good, it works well", but can not write articles like "Unicorn is Unix". So Passenger's creator need to write article themselves.

I'd be interested to know if some people do not feel (entirely gut feeling is what i'm referring to, no hard data required) that the world is headed towards another world war? If you do not feel that way, please elaborate on how you feel the events around the world transpire into your view of reality.

I'm not sure that this is meant to be a replacement for a mouse -- seems more like an additional tool for specific tasks (like the Photoshop task mentioned in the article).
I am late to the Lyft party, but after recently leaving Uber because I did not agree with their questionable business ethics and attitude toward their customers, I must say I find the whole Lyft experience somewhat refreshing.

Funnily enough, my first Lyft driver I had a week or so ago was telling me he leaves home a couple of hours earlier, does a couple of trips close by to his work and then on the way home from work he turns the app on and most of the time he is fortunate to get a ride that is going the same direction, so it pays his way home.

Not an entirely new premise, car-pooling has always been a thing, but for my driver (his name was Brett) this is going to be an awesome feature and I imagined many other Lyft drivers. I like the feature of the app that allows you to tip drivers a little something extra when a driver has gone beyond what you are paying them for. In my first experience, Brett offered me and my pregnant wife a muesli bar, bottled water and even held an umbrella for us while we got in and out of the car.

Seriously good job Lyft, you have a superior app/service and great drivers, you just need to get the numbers up and get some more brand awareness.
Short answer: no. I just wrote a long diatribe attempting to explain why using my very limited knowledge of semiconductor physics, but realized I couldn't do so without making some substantial guesses.

So instead, I'll offer some (probably fallacious, but likely still correct in its conclusion) logical deduction -- If this was likely to be a good photovoltaic source, the inverse would also likely be true. That is, that good photovoltaic sources would emit heaps of light when a current was applied.

In short, LEDs are semi conductors optimized to have a very specific direct energy band gap which produces photons in the visible light spectrum. This causes the semiconductor to shed excess electrons as visible light energy.

Photodiodes (used for PV arrays) are similar, but optimized for a completely different goal. They attempt to maximize the size of their depletion region. I don't know that the energy band gap is as important, though I'd imagine the narrower the better. Either way, this is done to maximize the likelihood that an incident photon will excite one of the molecules in that region of the diode, thereby freeing up an electron and causing it to flow around the circuit.
I've only seen pictures, but it seems plausible to be able to take Nth degree strips and add some kind of thin diffusion film over the surface, to remove the speckled look. Certain materials can also absorb blue and re-radiate multi-spectrum light.
Very, very low. I won't go into too much detail here, but LEDs and solar PN junctions (aka diodes) have very different designs.

The two big things I will mention are that LEDs are made with direct band gap semiconductors whereas efficient solar cells are made with indirect bandgap semiconductors.

The other issue is that solar cells rely on as big of a depletion region as possible to collect light whereas in LEDs the depletion region is considerably smaller.

It is very hard to disassociate his apparent views from his mental illness. If you've followed his past posts, you'll have seen the level of coherence change dramatically over the years, and so has the level of slurs and offensive language.

So it's not at all clear to me whether or not the apparent racism is ideological in any meaningful way vs. being largely a product of his illness.
I'm always suspicious of LED room lights when they don't state the price upfront. They've been pretty price in the past, but the cost is dropping quickly. Some quick Googling found http://www.environmentallights.com/led-light-panels/ultra-th... which has 24" x 24" 17W panel for $250. That panel outputs 3000 lux == 3k lumens / sq meter = 1.1k lumens for 4 sq ft. This is the same as a 75W incandescent bulb. A standard 13W LED bulb is $16 for the same amount of light.

So the price needs to drop by about 1-2 orders of magnitude before these become practical for most people.
You'd have to get more precise before I would agree to a prediction. I'm sure there will be something that could reasonably be called a world war some time in the future, so in that sense we are "headed towards" one. I wouldn't claim with much confidence that it will happen in the next, say, 50 years.
Is “Bottom-Up” the New Standard for Getting Products in the Enterprise?
Pretty sure I've seen this on HN before. Can't find the link, unfortunately.
We just replied with very similar responses!

FYI solar cells would not make good light sources since the most common ones (silicon based) are indirect band gap. For LEDs (and lasers) a direct band gap material is required.

You are correct about the depletion region needing to be large for solar cells, but narrower is not necessarily better. This is because if you make the band gap super narrow (say 0.5eV) and most of your energy comes in as much higher energy photons (1eV+) you are discarding all of the energy besides that 0.5eV from those photons. The band gap is tuned to get the highest responsivity at wavelengths where the most energy is coming in if it is tuned at all.
I don't see that Uber has permissions to my SMS, however, after going through the other list of granted permissions, I went to the settings and modified the permission and also enabled privacy guard for the app. You can go to Settings -> Apps -> (scroll down) tap on Modify - screenshot http://i.imgur.com/AVXLqgh.png
Moschetti's Architecture Principles
The system in iOS is still not enough because the app knows if you declined, so it can keep asking you ad-nauseam until you either accept or until you uninstall the app. For example Facebook's messenger asks for being able to show notifications every time you load the UI.

It would have been good if there was a way to lie to the app. For example if it wants access to your contacts, it could get a blank list.

Of course, it is much easier to not use such apps in the first place. Uber is not alone in doing this and personally I take it as a signal of how I'll be treated as a customer.
I have a lot of respect for Rob Pike. Doing what he says guarantees correct operation in typical cases, when the memory is cacheable. If CPU arch doesn't support unaligned loads, the compiler must additionally be able to deduce pointer alignment or it's forced to generate separate loads.

However, if performance is important, doing what Pike says doesn't always make sense. The case discussed in the article in question is one those.
Agreed, i was just about to say the same thing with this vid:

From my time in Seattle, Friendsgiving and Friendsmas was probably the best feature of American culture that I experienced. I lived in the University District, and my future wife was in graduate school at the University of Washington. There was always somebody around at holiday times so rather than than sit around thinking about why they were not on a plane going home it was time to get on the phone and get cooking. Even when going to the homes of almost complete strangers it was always an enjoyable occasion. Lots to drink always helped but the lack of family-related stress while not being alone was a big part too for which many people were quite grateful.
The key phrase is the line quoted is "default configuration". According to PostgreSQL docs, the default isolation level is "READ COMMITTED".

Your example check constraint indeed appears to work as advertised. Trying

UPDATE account SET balance = -1.00 where id = 1;

gives an ERROR message re:
new row for relation "account" violates check constraint ...

Still it's not clear exactly what the author sees re: where postgres fails. I'll have to read the article again. With any luck someone more knowledgeable than I am will shed light on the question.
That's why you need to lose exactly one move to make it symmetric. Like my original comment said.

And we don't want symmetry on one board, but between two boards.
The briefings I received as part of certain government procedures related to information protection left one impression more than any other on me: narcissism and ego are two of the most important motivations a certain kind of person has for doing something. Every person in every espionage profile I saw in those briefings had one thing in common: the spies thought of themselves as better than, above, or otherwise separated in a superior way from their peers. They were smarter, more daring, had higher tolerances for thrills, whatever. Financial motivations were rarely relevant, and when they were relevant they were only tangentially so (e.g. acting as a catalyst to engage in even more risky behavior).

Perhaps a similar thing is at play here.

Oh man, this reminds me of troubleshooting a host behind a router that didn't support window scaling.

Sadly, filtering is a privilege only rooted Android users may enjoy despite there being a perfectly functional iptables/ iptables6 instance on every phone.

The first thing I do after rooting is install a front- end to iptables and set it to whitelist mode. Any app that has a genuine need to access the internet can then be authorised; everything else is denied.

It frustrates me greatly that the ' common user' is denied this protection.
I have never heard of this guy. His work and commentary are totally awesome! I have heard more original things and phrases from him in 30 minutes than in the last 2 years!
Speaking of self-awareness, should there be a test akin to the Turing test to look for this? It seems that it would be fairly simple to simulate self-awareness, given that it is necessarily a subjective experience, so it seems you would want to look for something more than the most successful simulation. I'm sure we're nowhere close with computer programs, but one might also apply such a test to goldfish or oak trees.

The Increasing Trend of Online Extortion
You're right and the article eventually gets to that but not before using some socioeconomic sizzle.

To recap, the article opens with a URM female getting shell-shocked in her first semester. She's overwhelmed and sinking. The author then jumps into broad socioeconomic analysis of outcomes. Fast forward 23 pages (!!!) in the article, and a re-direction to the actual success factors (Grit™)...you learn that she made it through the fall with a B+ in Stat and a reasonable 3.0 freshman GPA. I'm happy she turned the corner, but I...felt misled >_<.

Though I really enjoyed Paul Tough's book How Children Succeed, I take issue with his claim:

It is only students facing the particular fears and anxieties and experiences of exclusion that come with being a minority — whether by race or by class — who are susceptible to this problem. Those students often misinterpret temporary setbacks as a permanent indication that they can’t succeed or don’t belong at U.T.

It's not limited to minorities and women...UT's no joke -- like many colleges. The honors programs (there are many at UT) are lights out. It's a humbling experience, and it's not surprising to hear that the article's poster-child, who "never had to study for math tests [in high school and] aced them all without really trying" got pooped on freshman year. I don't have the numbers but plenty of kids, regardless of URM status, got/get their bell rung in UT freshman courses.
I don't think we're headed for another WWI/WWII style total war between superpowers and their allies. I think we're more likely to get 1984 style perpetual wars against countries and concepts when they're politically convenient, fought by professional soldiers that are increasingly disconnected from the rest of society so that the illusion that everything is normal can be maintained. One could argue that we're already pretty much there, but I could certainly see it getting worse.
Congrats on shipping! And looks like a really nice game. What framework did you use for cross-platform development?
The economic situation of today is not conducive to global war. Our whole system is now based on international trade and skilled labor. When war breaks out what happens is the skilled labor evaporates, destroying the local economy, which then percolates into the global economy. Simply put, a world war is now too expensive because governments wouldn't be able to simultaneously fight and keep their population fed. Only if you had the right mix of dogmatic leaders who were willing to throw their own people under the bus and had the support of troops to do so (think taliban) could it happen, but given the gradual decline of populous religious extremism in most regions (except the middle east) i doubt we could get to that point any time soon.

Then again, world war 3 might break out next year. You can never tell such a thing in advance.
Kickstarter for Joybubbles: The Documentary Film
There are hundreds if not thousands of artists who can recreate some of the most famous and technically difficult paintings of the past 1000 years and yet they're lucky if they can sell their original work at a garage sale.

Art has very little to do with reproducing what the eye can see, in fact some of the most renowned art does exactly the opposite.

If you're confused by Rothko I hope you never come across Duchamp.
No. At least not like WW2, the costliest war in human history. Huge operations consuming thousands of tons of ammo per week, millions of combatants costing dozens of trillions of dollars that could be ended all at once with a hydrogen bomb that a country as small and poor as Pakistan controls just isn't feasable not to mention how much more at stake there is.
If 'white' doesn't refer to skin color, then you are just babbling worthless information and making racism worse. You are essentially making 'white' mean 'qualified potential employees'.

I do not feel that world is heading towards another world war as it happened in the XX century.

Why?

Putins daughters live in Europe/US. Same for childer of other Russian top government officials. Same for China. Who will go for total war?

On the brink of the war western military may assassinate the top government officials of the enemy hawk faction using fly-bots or some other kind of high tech minidrones. I have no information on the current capabilities though I've read about some of those being developed.

Asteroid mining will change the incentive structure for total war.

Further AI development will change the incentive structure for total war.

The world becomes less violent with every passing year. Look at the gapminder data.

We will see lots of local conflicts, hunger revolts, sectarian violence, mechs-human battles in Middle East and other futuristic tropes though.

> However, even if it is, so what? Why exactly does that behavior get to be overlooked as though it doesn't have a real effect on people who suffer from it?

Many places employers are technically - though it's nearly impossible to police - in theory required to attempt to offer reasonable accommodation for physical or mental disabilities.

His behaviour does not "get to be overlooked", and certainly would pose substantial problems, but it is a reasonable question to ask if it is possible for someone to accommodate him in a way that does not put undue strain on other employees or clients.

As for your "while non-white people struggle to find work in tech", it is irrelevant to the question at hand: One injustice does not justify another.

In this case, furthermore, nobody is starting a campaign to get racist bigots jobs in tech, nor do I see any serious attempts at providing him assistance to find a job. People are exchanging a few messages expressing sympathy for a specific person with a known mental illness who has been a visible and at times admired part of the tech community for the last two decades.
You can get TNs good for 1 year or 3, but you can technically renew your TN status as many times as you want. The downside is that TN status is strictly for people with "non-immigrant intent" and if a border agent believes you have immigrant intent when requesting a TN or entering America with one, they can revoke it/deny you entry at their discretion. So a 3-year TN is fine, maybe even a second one, but if you've been in the US on a TN after 8 or 9 years you're probably going to get some trouble.
Why I'm taking time off MIT
It's a good tool, certainly much better than the play store's almost hidden "View permissions" link.

Perhaps it can be enhanced to take into account API level differences too, since that sometimes has a significant impact on what the app is allowed to do.

For example, READ_CONTACTS allows an application to read the user's contacts data, but in IceCreamSandwich and lower, it also allows the app to read call logs, which is an altogether different set of data in the eyes of an end user.

Combine that with INTERNET permission, and basically you have an app which can send all your call logs to whomever it wants.
Firefox also has a built-in HSTS preload list, which I believe uses the Chrome list as one of its inputs: https://blog.mozilla.org/security/2012/11/01/preloading-hsts...

What Are the Easiest Thanksgiving Break Projects to Do with Kids to Earn $1/day?
A few years ago on a weekend break, I wrote a single-page product review with a domain registration and keyword mojo that soon earned $1/day in referral bucks. It died due to Amazon sales tax policy kicking me out of the affiliate program.

Since there's a long Thanksgiving weekend coming up, and I'd like to re-create for my kids that thrill of doing something small that produced measurable results.

What are the best pico-options for teaching them the thrill of pico-entrepreneurship with only a keyboard and their minds?

The $1/day is arbitrary--mainly just looking for how they could learn how to convert digital effort into measurable financial results.
Forgot pass to encrypted email, am I doomed?
I guess this is one of those cases where you just need to get your hands dirty to really understand it.

Can you do reasonably efficient [arbitrary size] fixed point arithmetic on your hardware? Do you have 64-bit add with carry and 64-bit multiply with 128 bit results? I'm interested in 64.64 and 128.128. Needed operations are add, sub and multiply.

I think compute grids like these could very well be an important part of computing in the future, maybe even the most important part. Ever since when I first saw an article about transputer. Grids or VLIWs, sadly software is always the pain point. I wish you luck, please get this working and right.
Down voted for praise? Well...
They say there's two distinct claustrums ("claustra"?) so shouldn't they be asserting there's two singularities of experience? Perhaps there's two consciousnesses in the typical human brain!
Oddly enough, we just always called that Thanksgiving. Sometimes we visited family, sometimes family visited us, sometimes we just gathered with whoever was around.

The need to create some sort of alternative label confuses me, but then again I grew up semi-nomadic.
Microsoft is hiring plenty. Go to https://careers.microsoft.com/search.aspx and search for software engineering jobs, the result is "only the first 500 results are shown."

Broad layoffs like what Microsoft did often serve as cover for divesting from product areas or culling dead wood (despite many US states being at-will, it can be surprisingly difficult to fire someone who isn't performing at a large company).
