Haven't really setup a dev blog yet, but I will soon. In the development side there isn't anything overly complex actually. The app doesn't use any graphics/gaming library, it's developed in native Android targeting versions 4.0+, mainly to avoid spending a lot of time testing and adding patches for older devices. The backend is done in ruby but it will probably be rewritten in erlang/elixir in the near future if the game gains traction. The main reason being that my friend which developed the backend works full time as an erlang developer and is eager to try out elixir on a real project :)
> I never used one once in my entire school curriculum, and don't feel like I suffered for it.

I'm glad someone else said this, because I wasn't going to admit to it. I got through 4 years of high school math and science, and four years as a CS major/math minor and I don't remember ever using anything other than the permutation/combination functions and some basic graphing. The TI-83 was much more important in getting me into programming than doing real math.

+ Saddam failed to cooperate with UN inspectors because he was continuing to develop weapons of mass destruction.
- If Iraqi authorities had destroyed their WMD stocks and abandoned their programs, they might refuse to fully acknowledge this to the UN to maintain Iraq’s regional status, deterrence, and internal regime stability.

I wonder whether the internal decision making at the CIA before the 2003 war was really as simple as that.

you don't need to work at a startup, you should have founder friends or even mentor types from people who are around 12 months ahead of you. if you can impress some small group of people you should gain access to their network and so on. there are other serious benefits of frequently talking to people in the same situation as you (startups can be extremely depressing for one)

I'm not sure there is really hate for TI calculators, but rather a general sense of "wtf are we paying for" when they've been the same spec and the same price for 20 years. No one really thinks they're bad calculators, but really they should be $20 by now, with a $100 color version or something to round out the high end.

There's probably something to this. I've been a miserable old man since the age of about 19, and I'm now 31, with arthritis, gall stones and kidney stones.

I think it was Seneca who said something along the lines of "When I think as an old man, I have become an old man.". This isn't new knowledge, but something that we seem to have to keep reminding ourselves of.

Also, placebos.
Honestly, once you learn 5 or 6 languages/frameworks they get really easy to learn. There is not a lot that is truly new with different frameworks, just different combinations of the same things.

As a math teacher, this is pretty interesting. I like anything that adds impetus to the discussion of how much math everyone needs to learn.

Trying to determine how much to let students use their devices in class is an interesting question. On the one hand, I want students to know how to use the devices they carry every day to solve the math problems that come up in their lives. I'd rather they learn to use the calculators they have with them, on their devices, than have them strictly use the classroom calculators we have.

Developments like this make it a little more challenging to monitor whether students are using devices to deepen their learning, or to avoid learning.

Slick is not without flaws. After using it for more than 2 years and following each new release, I ran against its limitations quite often and started looking for other DB libraries that supported some kind of type safety.

But of all the other libraries I tried (jOOQ, ScalikeJDBC, and some others) none of them were as elegant and easy to use as Slick, although some of them are easier to set up.

Right now, Slicks SQL queries are not optimized, so you better use a db that's good at query optimization (i.e. not MySQL 5.6, which will do unnecessary full table scans for some of slicks generated SQL)
This isn't "in place of" any research: This is different and honestly, it is hard to tell if this will wind up being important or not. This is research that is testing how to make people feel better as they age. I mean, if someone could feel just a little better and that little bit of feeling and performing better means they are able to move more and be healthier and stuff? Besides, this is looking at the mind-body connection in aging. Maybe this leads to research on different ways neurotransmitters react and the result of aging on the chemicals - and on and on. Maybe this research will inspire others. Research can lead to more research, when allowed.

Are there any platforms where writing and maintaing large documents is not an exercise in frustration? LaTeX is great but it's not what most people would consider "easy." From my observations, non-technical people don't get Markdown, reST, or other markup-based formatting at all.

Of course people have. People are being tortured to death by governments this very moment.

The point was the utter insanity of it all, of the same way of societal organization of rulers and subjects continuing for millenia on end.

Tyranny intensifies, and tyranny loosens up, but no matter how many times our rulers prove to us that having rulers is a bad idea, the masses keep accepting them anyway.

I'd attribute it to the lack of pre-entrenched cable TV service.

If you want to connect a home, then the expensive part is laying the cables. If you've put in copper already, then putting in fiber is expensive; but if you're putting in a cable now (or recently) then putting fiber instead of (or in addition to) copper is cheap.
Where is the economic benefit except for those two cities? Do a bunch of politically connected people have homes in Baltimore? High speed trains do little if nothing to ease commutes for the middle and lower classes, if anything they serve the rich while acting as political landmarks and budgetary landmines.

Considering the track record they have big projects in that area, namely Boston's Big Dig, and how much money alone gets blown on light rail where estimates are wholly inadequate, this seems like political grandstanding or distraction.

Since she finds a strong shorter-telomere association in neither equally sweet juices NOR in diet soda, this result probably just unhealthy-lifestyle-correlation (e.g. drug addicts and undiagnosed diabetics drink more soda). Also, “The extremely high dose of sugar that we can put into our body within seconds by drinking sugared beverages is uniquely toxic to metabolism” (from her Time interview) seems an overreach. A properly functioning metabolism can handle some sugar, even in a spike.

The sugar is causing the damage. Some studies also show some types of fruit juice being damaging, filtered juice being less healthy than unfiltered ones for example.

One quote from Wikipedia on the issue

"The total state of oxidative and peroxidative stress on the healthy body, with the AGE-related damage to it, is proportional to the dietary intake of exogenous (preformed) AGEs and the consumption of sugars with a propensity towards glycation such as fructose and galactose."
For a grad student looking for a PhD subject and advisor, taking such rankings into consideration is just mad. Doing a PhD means that you enroll for a multi year relationship with both your subject and your advisor. Choose qualitatively, with your mind, your heart and your gut, not quantitatively.

Ask HN: iOS or Android for a beginner?
I'd like to build a mobile application for a personal side project, but I've never done any app development before. I don't really care which platform I use. I'm just looking for the one that will be the fastest and easiest to pickup. There seems to be a lot of disagreement on the web so I thought I'd ask here.

The core parts of the app will be parsing a QR code and accessing GPS to relay the user's location.

If it is at all relevant, I have a MS in mechanical engineering and I've done a fair amount of C++ and Python coding for other projects. I would say I'm probably just past the beginner stage for HTML/CSS/jQuery, but not comfortable enough to go write a web app without a lot of questions.

Thanks in advance for input.

I'm not sure I'd really call Amtrak a railroad in the conventional sense of the term. With a few exceptions [1] they neither own nor lease trackage, and merely have legal access to trackage on fairly low-priority terms (the track controllers give them something like "best-effort" access, with no teeth in what constitutes a good effort). They're mostly a weird conglomeration of the former passenger services of a bunch of railroads, which were glued together and dumped on the government in the '70s in order to keep them on life support, but with no mandate to do much of anything but run the former services glued together on top of the trackage that was retained by the former operators.

Progress Software Announces Intent to Acquire Telerik
Impact Investing: Money That Aims to Pack a Positive Punch
While it's probably smoke screen, it's outright stupid and very harmful. The context is a bit more complicated than Hungary doing business with Russia, the government probably does need this money as it's doing stupid (and counter productive) spending to increase their popularity among the the less educated and the ones who are less willing to think critically. From this perspective, their move is clever: it's smoke screen and they can back up later and they win or they don't have to back up that much and they also win. The only way for them to lose is if it turns out to be an ignition bomb (much like the plan to cut the trees in park Gezi in Turkey).

The move itself, even with an upper cap of 3-10EURs would be devastating and pointing to the wrong direction. Hungary's only option to rise would be education and the strengthtening of the IT sector. But that would need at least 10 years of investment and we're still only talking about it. BTW, there was a news bite I think on the same day that this utter stupid move was announced, that we should make the IT education stronger, we should teach more IT in elementary school, blah-blah. Sounds like something that should have been (and indeed have been) said in like 2000. Yet nothing happened, apart from cutting back IT classes last year.

This is yet another step in the wrong direction. Totally wrong direction.

Oh, and the context: the national tax authority has been known and proven to support criminals who stole around 30M EUR of VAT/yr. It's been in the news, nothing happened. Then the idiots tried to force a US company to pay them (high ranking officials of the tax authority) to launch attacks on the competition of the said US company. That's when they notified the US authorities and that's how prominent Hungarian politicians (and/or their immediate comrades) were banned from the US. And this is what this smoke screen is intended to cover. Hopefully it will add up in the heads of people.
>'$10B seems exhorbitant for a 40 mile stretch of track + trains etc.'

Perhaps, but it's right on par with the cost of the recent Metro extension which cost $6.8B for an 11.6 mile extension running on existing tech.

Successfully building an entirely new Maglev line for 'only' $10B would be a steal relatively speaking, but I don't see that happening.

More likely, I'd expect the planners want Government buy-in because they recognize how susceptible the Government is to chasing sunk costs and covering all the difference when the project predictably balloons to 5x what was proposed.

The way you put it is the closest I've found to my opinion. I mean, it's definitely not just a mindset when you realize you can't run as you did when you were 20 and played football, but maybe you haven't even noticed cause you haven't played football since your 20s. If it is a mindset, it's one that heavily depends on the moment.
Some problems have several steps or techniques that need to be applied. It's not always obvious which way to go at first. Near the end of a course, or in higher-level courses, there could be hundreds of possible "next steps" that you've learned. Recognizing common patterns doesn't help in uncommon cases.
Sam: I'd live to see a discussion on putting together a party round at the seed stage. I'm not sure how common this is, but we have over $1M of interest in our seed round (angels/micro VCs), but we're operating in a space where very few investors have any domain expertise, and so everyone is waiting for a lead. Is this common? Any ideas how to push this through? In the mean time we're taking the Steve Martin approach.

Cool idea and nice app
It isn't a UX problem, it's a political problem. It departments are responsible for, among other things securing their company's computing resources and ensuring their availability to support the business. The most expedient way, in their view, to accomplish this mission is to keep as much direct control over those resources as they can, even if it means the users are "inconvenienced". Add to this the human tendency to inflate the importance of your own problems and deflate the importance of other people's problems and you end up with a situation where everyone outside of IT runs crippled machines or thin clients and has to call on IT for every change or update of substance.

There is a happy medium, but IT (largely) is not interested in it. The current system meets their needs very well, but they have lost sight of the needs of their users.
I saw the demo yesterday; it looked like you still had state in the form of a world value (at least storing Mario's physical state information). Those world values would have to be kept around.

Elm code is only pure in that it doesn't have implicit side effects, it definitely has state.

However, if you have deterministic execution, you can always just re-execute from the beginning to get the same execution. This works for functional and non-functional code.

Over the past several months we have developed a ranking based on a hard, measurable method for the top 50 U.S. universities.

"Hard, measurable" != meaningful.

And counts of articles published are especially meaningless as measures of the quality of either the research actually done in these departments, of of the overall educational experience at those places. It's like measuring developer quality by LoC committed, or the number of JIRA tickets they've closed.
It can be :) What you're talking about is the typical CPG (consumer packaged goods) model: a product manager would be responsible for selling that product, identifying a market, etc. The work isn't really all that different, but CPGs don't usually require much deep knowledge.

IMO, product in tech companies is a much more exciting role because you get your hands dirty with creating the product. Let's say I'm the product manager for Facebook's News Feed. I would work with designers, developers and marketing folks to determine the features of the product. For example, I could say "Hmm, let's show more ads to people between the ages of 18 and 29 than we show to people between 13 and 18". We would test the hypothesis either through focus groups or A/B testing and determine if users are like/hate/neutral on it, and if they're like/neutral and it provides more money, it's now a feature in the mainline product. The role is slightly different at different companies (product managers at Google are expected to write a little code and lead engineering teams, for example) but the core tenet of the job is answering the question of "What should the product be?"

Product management is the central role at any startup for the first few years. A good product manager is worth their weight in gold. A great product manager can make you billions. For me, it's the perfect mix of creative, technical and business disciplines. You have to have the vision to see what the product can be, the technical chops to know how to get it done, and the business sense to know what levers you should be pulling at any given time.
