This seems like it's going about solving mobile UI problems backwards.

I think a better approach would be to fill in the gaps between what a graphic designer is used to (Photoshop, Illustrator, Fireworks), and the UI tools that the different platforms offer - Interface Builder and the XML Layout editor for Android.

Interface Builder is definitely visual enough for designers, but most of the "cool" effects for modern iOS apps can't be done purely through Interface Builder.

The Android Layout Editor in Eclipse has a lot more control over features, but I wouldn't expect graphic designers to start creating drawables in XML either.

My thoughts would be to work within the Photoshop ecosystem - a plugin that exported XIBs and Layout XML would probably be the easiest way to go.

Unfortunately, politics in general is usually a rejection of critical thinking skills. The Texas GOP is just openly recognizing that.

Anyhow, it's a good insight into today's GOP. This stuff has always been around, but the party out of power always tends to go batsh*t crazy.

The dog owned by my niece in Taiwan has been on Facebook for more than a year. (I haven't bothered to friend the dog, but I keep up with my niece's news via Facebook.)

"Duplicate profiles - belonging to already registered users - made up 4.8% of its membership figure."

I have plenty of American friends (mostly married women with children) who use pseudonyms, and plenty of those have more than one Facebook account to distinguish personal friends from work colleagues.

"Last month, the BBC's technology correspondent Rory Cellan-Jones set up a fake company called VirtualBagel to investigate allegations of fake 'likes'."

The BBC investigation confirms what most of us regular Facebook users know from personal experience. A lot of what looks like user engagement on Facebook is just faking or fooling around, not something on which to build an estimate of future monetization of Facebook. I'm still not seeing how Facebook can do any better than AOL did at increasing monetization without driving down the satisfaction of users.
My experience with this sort of thing is that despite thrice-weekly lifting sessions, I lose a LOT of muscle. Just a heads-up for anyone thinking of trying this.
Good. Less management, more engineers. Facebook is profitable, and Zuckerberg has 56% voting stake in the company, so screw everyone else. I say let Mark do whatever he and his engineering team want to do, and don't bow down to people who would rather make a quick buck than build a great company.

That is the entire point of having the books in a stack where you can see them!

I love reading, but I intentionally take up books for leisure reading that I know will be a challenge. Some longer or more difficult works are definitely projects, projects that I need to consciously put work into.

Having the book sitting out there, visible, a physical reminder, is probably my most powerful motivational tool for getting these books read. For me this is the main reason I still buy and read physical books.

I guess it also helps that, for me, reading is something I get excited about. It is how I unwind. Having a book in my library that I haven't read yet does not make me feel guilty. Maybe the book makes me excited with anticipation, maybe I feel apathetic towards it. But I don't feel anxious, because the world will keep spinning just fine if I fail to read a book.

edit: I should amend to say that this is also a matter of taste. Having books all over the place will definitely make you switch reading material sometime, and will probably keep you from finishing some books. I'm of the school of thought that says, fine. I'll fail to finish some books. Not the end of the world. Sometimes a book just takes a couple of tries before it gets its teeth into you.
Oh, not this again. It is clearly saying that they are opposed to Outcome Based Education, which is also call "critical thinking" by proponents. "critical thinking" in that sentence is clearly used as a synonym for OBE. They are saying that they oppose OBE because they believe it is a vehicle for undermining beliefs on social issues and probably religion as well, rather than teaching math, science.

I have no opinion on OBEs or teaching methods but this is just political games on top of a very poorly worded sentence is some stupid platform document that has very little to do with anything anyway. Let's keep this political BS off of hacker news.

I'm as bored by micro-updates about FB's share price as the next person, but consider two propositions:

1. Drastic drops aren't the only interesting ones. If FB were to decline slowly all the way to (say) zero, presumably the decline would have become interesting and newsworthy sometime before that point regardless of the slope of the decline. Where exactly is this point? Who knows. But given the human mind's heightened interest in multiples of 10, $20 seems like as good a candidate as any other. (Along with probably $10 and $5.)

2. Whether you believe in them or not, stock prices are said to have psychological support levels. Above price X, the investing public is inclined to view a stock favorably. But if it drops below that, a new narrative may begin to emerge that itself can have an effect on the price. You call this "nonsense" but provide no evidence in opposition to the conventional wisdom. It may be that "objectively" there is nothing special about the number 20, but markets are made by interactions between people and in modeling the behavior of people, psychological facts are relevant. One psychological fact is that people take an interest in multiples of 10, and movement across them can therefore have significant consequences.
My impression is that there are issues with 3rd party licensing of various sorts in the proprietary drivers that would prevent open sourcing them even if Nvidia/AMD wanted to.

Of course that probably doesn't prevent them from giving the OSS drivers some love, but that is another story.
Simple: programmers' productivity has very high variance, especially in team project. It's not because programmers are unpredictable, it's the nature of the work. Some main reasons are:

1) Programming (by that I mean R&D, not configuration/deployment) is, by definition, creating new stuff. So unless the new project is very similar to a previous project, even experienced developers wouldn't be able to provide good estimations.

2) There's always a degree of tradeoff between reliability and new features in every design decision. Should I use the new version of this library with more functionality but has not been tested with current code base? Should there be an incomparability, do I have the time and expertise to work it out? etc.

3) Dependency on other team members and/or other teams.
I think a big part of the "low blood sugar" complaint is people misinterpreting their body. I used to get "low blood sugar" if I didn't eat for six hours or so, even getting headaches from it (I think 60% of the headaches I've gotten in my life have been from the placebo effect, and the rest stress-related).

People are just so unused to being hungry that they freak out when it happens.

I think it's fine. Most people, space nerds or not, realize that rockets sometimes go boom. Unconsciously, we all recognize danger when we see it. The problem is that we want to be placated, so when someone comes along and says "the Space Shuttle is perfectly safe" most people want to believe it, even though deep down they really don't.

Saying that "yes, that thing you think is dangerous probably is, but we're going into this willing to take the risk" will be accepted by most people because it's what they intuitively believe anyway .
For an example of this, just look at NASCAR.
I think that applying statistical methodology to the study of history might provide some insights into cause-and-effect and the situations surrounding historical events. But, I seriously doubt that there are any "cycles" to be found.

For one thing, major events in human history absolutely are (or have been) pivotal on just one or a few individuals. A fun book on this is, "What If?", by Robert Cowley. Also, "How the Scots Invented the Modern World". Being the right person, in the right place, at the right time has been a recurring theme throughout history. For example, the final vote for the unification of Scotland and England was led by one passionate, older man -- who died of a stroke later that night. Had he died the night before, it's likely that his opposition, an almost equally skilled and passionate orator, would have won the vote instead.

The fathers-and-sons cycle described in the article is a relatively recent phenomenon, where society is settling down into a more peaceful state overall, and even then, the two greatest wars in human history violate the cycle: World Wars 1 and 2. Popular sentiment in the U.S. was against being involved in World War 2, after the horrors scene by the previous generation in World War 1, so the cycle isn't completely without merit. But, as usual in human history, there are too many other factors involved in the outcome.

I also think that history changes a lot depending on how you look at it. There are so many human societies on the planet at any given time, each one doing so many different things, that it's easy to step too far back in perspective by ignoring many of the events of history, and then start to think that you an discern some kind of a pattern or cycle. One of my favorite books for this is "Chronicle of the 20th Century", a collection of short-form news articles and pictures from the U.S. from 1900 through 1987. Flipping through that, it's always stunning just how much is so easily forgotten, how rich and complex each day was for the people living through those years.

> The deep call stack problem exists in any kind of parallelism.

Consider an event-based server that returns to an event loop whenever it makes a blocking call. At any point in time, most of the active requests will have a call stack depth of zero, and the rest will have just the frames since they were last unblocked. Contrast that with a threaded server where a request occupies a single, deeper stack for its lifetime.

Or consider an actor-based system where an actor has just a few responsibilities and communicates with other actors with messages. Contrast with a threaded system where the server's submodules have to communicate with function calls.

I don't see how stack depth matters much, though. There are way more important considerations.

I had a chuckle at this.

An alternative to consuming boring things is to create interesting things - which, incidentally, is what Makr.io is trying enable for more people.

So, take your "ridiculous boredom" and use it to create something ridiculously interesting for the rest of us (on Makr.io or anywhere else, of course).

Back in olden times, the occasions when you haven't been eating are precisely the times to focus.
The US has about half the world's aircraft carriers. Each aircraft carrier basically needs a battle group to protect it. The approach is indicative of the US's strategy: be able to have a few aircraft carriers anywhere important in the world, ready to quickly react to a crisis without sacrificing protection elsewhere. Since no other nation with aircraft carriers has more than 2 (and most have only one), that basically guarantees significant air and naval power anywhere.

>Is there some moral or legal obligation that a service's price must tie directly to its immediate costs?

No, but in a competitive market we would expect it to because competitors will lower their prices in line with their costs to stay in business. At least, that's the theory.

When you have companies competing on who can charge the most you have an indication that there is a lack of real competition.

Upgraded one machine from Snow Leopard (10.6) and another from Lion (10.7). No issues what so ever. Both still work perfectly, all my stuff from HomeBrew transferred over without any issues either (which is fantastic, did not want to have to recompile all of that stuff).

This is flat out ignorant. Is it "impossible" to google for credible studies about sexual assault. Like this popular one from 2010 by the CDC that interviewed 16,000 people (including 7,400 men) and found that 18% of women and 1% of men had been raped or had someone attempt to rape them. So to take the point home, you don't have to believe in a "rape culture", but just know that if you have a wife, mom, grandmother, daughter, and aunt chances are (according the CDC) that one of them will be raped or have to fight off an attempted rape in their lifetime.

"If the value of software we're writing is so low, it's probably not worth being written"

I think you are missing something big. Lots of software is like infrastructure. It serves a function and needs to exist so that function can be fulfilled. To use a metaphor, a lot of software is like paving roads. To pave a road costs a certain amount of capital. The amount of benefit derived from a cost-benefit analysis may be marginal. But it is a project that needs to be done. Moreover, it needs to be done in large quantities, which requires a lot of people. The solution in such areas is A) not to have the best people working on these projects and B) create formulas so that these things can be done quickly and efficiently -- ultimately automating as much as possible.

Basically, I think there are many tasks in all sectors that are about creativity and a certain genius, and others that are necessary but simply about volume. "Genius" should be expansive enough to recognize the importance of these latter tasks, whether it is building roads, providing glue between different cloud APIs, or dropping seed money into startups.
They tried with OpenGL 3, but then it took them years and the plan were scrapped. ( That is when Microsoft brings DirectX 9 to the table, which is well designed and much more usable then OpenGL ). They restarted development a few years ago to clean up the mess.

The main reason why OpenGL did not get a restart were because of pressures from CAD and 3D Modelling Industry.
How I found that was happening for me was looking in Console for Wake and Sleep strings, best of luck.

I remember having a series of books as a kid, iirc they were titled, "world of tommorow", or something like that. They talked about big-vision things; fusion, transportation, asteroid mining, and terraforming Mars by planting genetically-engineering algae on it's polar caps. Glad to see us finally taking steps toward that vision.
you have to wonder if the US govt has thought of that. Fear of another nation has spurred great advances in technology.
No, you're right, what I wrote was idiotic, they clearly are not going to develop the driver code from scratch especially when there's hardware bugs to fix in the drivers. I tried to mean that nobody else built/touched/integrated the drivers, that Apple had pretty complete control over the binary and what did and did not go in it (and likely what kind of code they'd integrate), related to that were things like their long-outdated OpenGL support (2.1 mainline until Lion, which bumped support to... 3.2 — by the Lion release, OpenGL 4.1 was a year old and 4.2 would be released a month later, 3.2 was 2 years old)

Although these days I'm it looks like they write significant portions of the graphic driver subsystems: when released their automatic graphics switching seemed quite markedly different from Optimus and completely independent[0], which is corroborated by them not wanting to restrict their ability to switch back to AMD.

My Point of View on Why Programmers Are Bad at Estimating Times
I went through this process myself in setting up a self-clearing BD, so I am fully aware of all of the relevant rules and regulations.

>Such checks are only as good as the imagination of the author.

SEC and FINRA regulations require very specific risk checks. One of those involves looking at potential positions if all of your (buy or sell) orders get filled. You have to sum your max potential gross position across all symbols and decide if you will trip a limit. If so you have to halt.

This is not imagination; this is codified. If you send an order for 100 shares, you HAVE TO ASSUME they were filled when you send the next order. That's the rule. This was not left to imagination.

"Which is all well and good until you have an issue where two independent systems creat a feedback loop. Such problems are only evident 'at scale'."

There should be no feedback where the trading engine affects risk check. In fact, the new rules require separate code bases and separate legal entities.
They did not gamble. Market making doesn't involve gambling. Someone checked in an egregious error that testing failed to find. The fact that it is in a trading system makes the cost of the bug easy to measure.
What's really funny is if i'd just worked any random job -- food service, shelf-stocker -- instead of getting all this "elite" education, my financial situation would be way better than it is now right now.

And if I, say, decided I wanted to go to school, then, knowing what I know now, I could major in something serious like computer science or one of the engineering disciplines.

I'm too lazy to look for a cite, but I think Peter Thiel has commented on part of the problem of the legal market being the "prestige" that is associated with being a lawyer vs other jobs, and how people are willing to make flawed financial decisions in part due to this perceived prestige.
