First let's level set: the benefit of taking vitamins is that if you take them regularly, at some point in the future you will be better off than you are now (in other words there is no immediate perceived benefit - it requires an investment). Alternatively, a painkiller has immediate physiological benefits.

Assessing a service as a painkiller vs a vitamin is not totally black and white - generally I would say a service qualifies as a vitamin if there is no immediate perceived benefit to its use (ie it doesn't meaningfully save me time in aggregate, does not enable me to do something else that I can directly ascribe value to, doesn't reduce a painpoint I feel at this moment). A mental test I use is if someone goes from using my service for two months to immediately not using my service, how will their workflow change? If it doesn't change meaningfully, you are likely a vitamin. Note that I recognize that by this definition Facebook is a vitamin. Vitamins can make money.

So back to you. If your service does improve work/life or actually provide a "factor of efficiency improvement" over whatever their alternative is (e.g. Doing nothing) you may have a painkiller on your hands instead of a vitamin. The problem is you aren't the ultimate judge of what is a painkiller or a vitamin (you are operating on a hunch) until you go out there and try to sell it. The market will tell you.

So my advice is to spend as much time thinking about how you will package and sell this service as you are designing the service. Create a few marketing materials, hone the pitch and sit down face-to-face with as many people as makes sense and pitch them. In fact, I am 100% happy to genuinely consider purchasing this from you so you can try it on me. At the end of the day, the customer decides if you are adding value by voting with their time and dollars so developing a sales strategy early is important. You may discover you have a great service for a specific type of buyer profile but finding that buyer profile is too expensive. It happens.

I often remind myself of Ali-G's pitch to Donald Trump of a glove to prevent ice cream from getting on your hands (if you haven't seen it please watch - hilarious). Anyone who loves ice cream has this problem and the potential market of people who eat ice cream is huge. You could probably find someone willing to pay $1 for it but there is no way anyone can build a real business off this. Of course, you never know.

I know many people personally who make 200k+, with less than 10 years experience. Many of them are also immigrants. Some of the ways they got there:

- live in a tech hub with high demand for programmers. The best places are NYC/SF and probably Seattle

- switch companies every ~2 years, and negotiate for ~25% comp increases when you do. There are some tips that can help you achieve this, but it's a blog post in itself

- work for a lucrative brand-name employer like Google/FB. First, you'll make a ton of money there. Second, having them on your resume will boost your future prospects and compensation offers

- in order to accomplish the above, get really good at interviewing skills. Practice topcoder, cracking the coding interview, fundamental algorithms and data structures, communication and presentation skills, etc etc. Whatever it takes to ace the interviews, no matter how dumb you may think it is

- be good at your craft. Read expert books, work on your own small side projects, push yourself to build high quality code, and not just barely functional junk. Do everything you can to become an expert in your area

- be a great coworker. Leave a positive impression with your manager and colleagues. You don't have to be their friend, but you want to be someone they respect and would recommend to their friends

I found that too! I can concentrate much better on a lecture with an increased speed. Never really thought about it but it makes sense that less pauses mean less occasions for the mind to wander.

It's been a gripe I've had with the Andrew Ng ML class: the audio is so bad that increasing the speed sometimes makes the lectures unintelligible. I appreciate lessons being offered for free but lecturers should really put more effort into the recording.
The main advantage of the course is that it's free.
If this is May 2015, this is prior to the system in question (HW2 or AP2) even existing in prototypical forms.

The previous system (HW1 or AP1) is a MobileEye chip, which is found in most other cars that also have "lane keeping" features. They all use the same chip with the same model provided by MobileEye, and can choose to overlay features on top of it or augment the system with other sensors (such as radar on the Model S/X). For that system, it is essentially the same performance whether it's a $150k Tesla or $30k Honda.

I think, homeserver software is also still somewhat immature. I'm waiting for Dendrite.

I'm evaluating Synapse (as all the other servers say they're pre-alpha incomplete) for the last week or so, but one immediate issue I had is that when I had set it up, on my home low-power NAS it required more than 15 minutes (and 0.7GiB of memory out of 1GiB I've allocated to the container) at fully-saturated single CPU core to join #matrix:matrix.org. And it took no less than a minute to join a room with just 200 participants. Sure, that's just for the first time, but it still feels way too resource-heavy, compared to other chat systems.

The machine has 10-year old Atom 330 CPU - which makes it an ancient relic, but hey, it has more than enough power to run XMPP (w/various transports), mail and web servers, and it just sits on a shelf in a kitchen, with a barely audible humming.

Thanks, this clears up some of the strange wonderment with the Intel 4004. For example, I never knew what the "status characters" in the data RAM chips were for. This manual suggests to use them to store sign and exponent, or program RAM addresses. They seem to be general purpose, though.

Note that there is separate "program RAM" and "data RAM", the latter having a more complicated structure with the aforementioned status characters. It's surprisingly complicated to address any RAM on the 4004, with both types of RAM having separate quirks for doing so.

There are also plenty of other oddities, like I/O ports on both RAM and ROM chips, dedicated instructions for e.g. "keyboard processing" but no AND or OR instruction (with horrifyingly long examples on how to implement them in this document), and some instruction names for seemingly straightforward things that are completely unintuitive.

It's well worth exploring.
Android is Apache licensed.

There's a whole thing about the Play Services absorbing more of the features, and I feel like it's a great indicator of the difficulties with open source.

A lot of people enjoy replacing the lowest level of the system with OSS. But consumers only notice that afterwards they have nothing on the highest level.

I think the Raspberry Pi took the right approach here accepting the binary blob GPU but having the software stack otherwise be free. They got adoption because things were useful! And now they "just" have to solve the GPU problem, instead of a "rewrite all software " problem.

I would be very excited by people who could offer a "skin " over Android (with its own set of apps) so the higher level stuff could be tackled. Once that part of the stack is nice, swapping out the backend will be an even easier pitch.

The counterpoints I can think of:

- If you do not trust the backend, hard to have proper security.

- People are doing what they want to do! Lots of people like writing kernel-y code more than a dialer UI
Tangentially: The mission of public universities, in the U.S. at least, is the educate the public (and do research).[1] Inexpensive online courses and resources (library, etc.) seem like ideal ways to accomplish that goal. Are they taking advantage of it?

> The survival of my loved ones -- and that's a category that can go across species -- is absolutely important to me. The survival of evil space Nazis? Eh.

The idea is that if it's between all people dead, or all people except evil space Nazis, I'll take evil space Nazis. Just because they are evil space Nazis now doesn't mean they will be hundreds of years from now, but they'll never get that chance if all humans are gone.

Human history is largely a story about bigoted, insular racist violent psychopaths becoming slightly less of each of those things over time. I don't see why that trend won't continue in general even if we hit a local maxima of fascist oppression from time to time (as this would be).

Because I love people, I can understand the concept of loving people in general, and want other people to be able to experience that. Human extinction means that nobody might ever experience that again, and I think that's a shame, and will do what I can to prevent that type of outcome.

> Many of us appreciate things that aren't truly keen from an evolutionary perspective.

There isn't appreciation of that type without people to do the appreciating. Your ability to appreciate it is provided by our current circumstances. I think keeping those circumstances active is worthwhile. Otherwise you are taking more than you are giving to the species as a whole, which is unsustainable if too many people do so. Even if you don't care about how sustainable it is, you would be riding on the hard work the rest of the species is putting into the system to propagate. Don't be taker.
This is counter intuitive but choice and freedom are the root of all errors. There is greater power in restriction.

The current movement towards functional programming exemplifies this philosophy.

>> A lot of it is cruft and motivation for the underlying core ideas.

Someone else made the exact same remark about Cal Newport's book "Deep Work" earlier this week in another thread.

I find this to be true about a lot of books/courses/content of a "self-help" nature that are designed to be practical and applicable - the real helpful stuff boiled down to its essence could fit in a tri-fold pamphlet (or a 350-line pastebin), but you can't make money selling a tri-fold pamphlet, so the content gets augmented with tons of case studies and variations on variations on variations of the core ideas to justify 200 pages or a multi-week course.

I stopped buying these kinds of books. Every one turned into "thumb to about page 60 to skip the intro/life story/motivating metaphor, read a few pages, and skim the beginning of each chapter after that."

Ask HN: What is hiring like in industry research labs?
Companies like Microsoft, Google, HP etc have labs that employ Phds. I had a few questions regarding them.

1) What does it take to land a research scientist position in one of these places? Do you have to be exceptional?

2) Do they exclusively hire Phds?

3) I read somewhere that 57% of Phds end up in industry. Does that 57% mostly comprise of these scientist positions? Do a significant number end up in jobs that don't require advanced degrees?
I hadn't thought of that sort of static analysis. I would guess that the most common variation of using "is" on integers is comparing to a literal ("if x is 3"), so conceivably the bytecode compiler could warn about that without even needing annotations.
Thats relatively easy compared to getting your first dollar. Having 40k in MRR suggests you already got a decent userbase to sell more products/services or retarget to. You can also get PR easier than a no name startup with 0 customers.

Bullcrap. APIs are either going to be irrelevant for solving an algorithm, or will simply do the job for you. "Implementing an algorithm" usually means writing it from scratch using simple data structures, primitives and basic flow control constructs.
So his approach is to go through hackerrank exercises to learn the language.

In case someone cares about these things, I compared the build times and the binary sizes for 1.9 vs 1.8.3 using the open source project we maintain [1]. This is on a 6-core i7-5280K:

Build time with 1.8.3:

real	0m7.533s
user	0m36.913s
sys	0m2.856s

Build time with 1.9:

real	0m6.830s
user	0m35.082s
sys	0m2.384s

Binary size:

1.8.3 : 19929736 bytes
1.9 : 20004424 bytes

So... looks like the multi-threaded compilation indeed delivers better build times, but the binary size has increased slightly.

We can also look at delta-V charts. Earth to the Moon is like 16.4km/s, Earth to Mars is like 14.3km/s using every available aerobraking opportunity (6.4km/s saved) and assuming 500m/s for the final powered landing. (The Red Dragon plan called for aerobraking from 6km/s to 540m/s and then switching to thrusters.)

Is that 2.1km/s really a whole extra stage? Or can it be met by reducing cargo capacity somewhat?

Two interesting points about Red Dragon - it wasn't feasible to put parachutes on it so its aerobraking would have been greatly limited. It wouldn't have much surface to use for deceleration in that case. I'm curious just how long it would have spent aerobraking, SpaceX's docs don't seem to mention that. And it was cancelled a few months ago with the intent of designing a "vastly" heavier lander, for which aerobraking will be that much less practical.

edit: But I can do a back of the envelope calculation. Decelerating 6500kg from 6km/s to 540m/s is 116G joules. The diameter is 3.6 meters so a molecule of air in from of the Dragon would be displaced (on average) 0.53 meters. Let's assume the atmosphere is a constant density (0.020 kg/m^3). Assume a drag coefficient of 0.05 (and ignoring the lifting body effect) that is around 200kN of force, tapering down to 1.5kN. That is like 3000 km of aerobraking at maximum atmospheric density and should take around 2300 seconds. But that depends a lot on the deorbit profile. I'm going to need a bigger simulation...

The parent comment's evidence that it's not making them happier - "The people wandering through these stores though looked dazed, alienated, and entirely out of place." (during the commenter's visit to the mall?) - is a bit sparse.
It's fun to bash on great accumulations of power, that's my instinct too.

But despite all the controversial things Amazon has done, they still seem to live up to their #1 leadership principle [0]:

Customer Obsession - Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust. Although leaders pay attention to competitors, they obsess over customers.

Since the first result of the WF acquisition is lower prices for customers, it looks like that tradition continues.

If Amazon makes good on their third principle, "Invent and Simplify", they'll fund lower prices with higher efficiency and greatly expand the number of people who can afford WF quality.
