Ask HN: Online Learning Resource for EE or Hardware
There are tons of sites and services cropping up primarily for web development or programming such as Udacity, Codecademy, etc... In addition to existing resources, OCW, books, etc...

There doesn't seem to be an equivalent for EE or Hardware related learning aside from going to school, hitting the books, etc... Please don't say "just dive right in". I whole-heartedly agree that the best way to learn is hands on but it would be nice to be able to have a solid format to go off of.

Background: I'm completely self taught. My entire background is completely on the programming side. I have pretty much little to no knowledge of where to even begin getting involved in hardware and all the resources I've looked into online are extremely vague and does not do a solid job breaking down things the way they do for programming and all the various things you need. For example, if you want to do web development, you'll need HTML, CSS, and Javascript on the front end (probably best in that order although not required), a choice of a backend language, etc... For hardware, there is a lot more working knowledge and I assume they build off each other, and its really hard to get any solid advice or a list of things in the order you need to learn them (short of going off some course cirriculum.

I get that there are things like the arduino and stuff out there and I've looked into it. But it doesn't really make the learning curve any easier to understand, or rather, what the heck am I suppose to learn in the first place. About the only thing I'm sure of right now is learning to solder and apparently starting with signals and counters. Can anyone break this down a bit better for me or provide better list of things I need to know, the order in which I need to learn them if there is knowledge that builds on top of another, etc...

I don't mind diving into books and doing whatever, I just need a general guideline if you will. Thanks.

I have started a company and sold it. Wasn't enough to retire yet and now I have a 9-5 consultancy job that pays a lot of money. But I don't have any stress any more and family time.

So both sides of the coin and depending where you are in life there is no right or no wrong. So judge only for yourself what's right for you. And keep your opinions/judgements about other peoples career paths to yourself.

Programming is an act. Culture has built up around it over the last half a century, but it's not necessary to take part in that culture just because you are good at programming.
This is remarkably negative. There are a number of ways to explore without having to break physics.

Constant 1g acceleration makes nearby galaxies accessible, nevermind nearby solar systems.

Returning from exploration? Reporting results? That isn't going to happen.

Colonizing the universe? There's nothing at all stopping it in physical law.

The only thing that struck out at me as odd from this announcement was that it wasn't phrased like: "Amazon is excited to announce!" (Most of you probably know what I'm talking about)...

http://blog.mailchimp.com/the-email-person-at-amazon-web-ser...

This is the first ever ever product announcement that I've ever seen Amazon make where they weren't excited to announce.

It is not doing what you love, but loving what you do.

Obviously you must make your job compatible with your personality first so you can get to love it.

If you are introverted and you choose a job in witch you are never alone you won't stand it, no matter how much you try(as you try harder you will hate it more and more).

If you are extroverted and you are required to work focused on single problems long hours alone...

There's much debate about this issue, and it's hard to come down on one side or the other, but the Shuttle had unique capabilities that no other system has had.

Imagine building the ISS without the shuttle, for example. Imagine servicing Hubble. Imagine returning large objects from orbit safely.

The shuttle cost NASA a lot of money that's true, but it cost the US relatively little, and NASA did a bunch of truly amazing things with it. There's good reason to be nostalgic.

NASA 1981: The Bug Heard Round the World
Nice post, made a few good points. But it's just a vain battle about a not so very interesting "manifesto" by some people who think they need to make some point (or whatever).

I'm not a 501 programmer for sure. I agree, that there is a culture as you describe it, but I strongly disagree, that every programmer somehow needs to be part of this culture. I have worked with many 501 programmers and often enough they do a good job and take away a lot of work during their office hours (especially the boring kind of work). Actually I think most everyday programmers are of this kind.

The part about pitying wasn't very smart and (as you say), adding a small piece of "respect" doesn't really help it very much. But to care about it, my first step would have to be to take this whole manifesto thing seriously, which I can't do. Most 501 I know wouldn't care about it too. Especially since it doesn't say much in the first place.
Curious about this. Monty (of xiph.org fame) claims[1] that the effective DNR of 16 bit audio is actually 120dB, not the 96dB you get by using the "standard" 6*(# of bits) formula, due to use of shaped dither (basically smarter quantization).

However, this DAC supports 24-bit audio, and claims a DNR of 111dB. He talks about guilt-free volume adjustment. That is, if you lower the volume in software, you're effectively decreasing your dynamic range because you're artificially limiting the range of values you can use. Makes sense. Is that the main reason you'd want to use a 24-bit DAC here? (Of course, this assumes you have 24-bit source material as well.)

Just really curious about this... I trust Monty's word on this stuff given his reputation and the amount of work he's done with audio. But the guy who designed this DAC clearly seems to know what he's talking about as well.

Why We Invested in Neighborland
I think it's the way evolution works. Sometimes it's slow for a while - then things click into place and there is rapid progress.

The Khan Academy (and other free online, high quality education) is probably the most revolutionary thing that has come out of the internet in the past few years.

I don't know how much effect it has at the moment in the developing world - whether resources like that are used in the classroom and by students - but the potential for transformation is huge. There is an enormous amount of people in the world with untapped talent because of lack of access to high quality education.

Biotech, synthetic biology etc aside, I think the next thing to facilitate change in computing is portable display technology - for personal use maybe it will be Google Glass once it's a mature product. For shared use I think low cost, lightweight high res laser/LED pico projectors will take off in the next couple of years. The computer itself will be a tablet/mobile phone, either with its own display or hooked up to one of these new display devices.

Battery tech is another interesting one - once we work out how to produce cheap, high energy density, long life batteries from a natural resource that is abundant, we'll see a lot of accelerated progress in several areas.

Of course the 1st world problems of not having enough cool gadgets and software will be put into perspective when the Earth's limited food/energy resources vs growing population starts playing out for real.

We're so enthusiastic about the possibilities the internet offers us that we want to do everything online now, even things we're hardwired to do irl.

We're "hardwired" to do everything IRL, simply because we couldn't have evoved to adapt to it in such a small period of time.

But here's others technologies that we weren't "hardwired" for, and which actually "re-wired" us: Language and Agriculture. I'm having an hard time figuring out how doesn't your argument apply to them too.

Inane chatter in real life causes your body to release hormones that make you feel good. Inane chatter on facebook not so much.

Well, I actually find inane chatter to be painful anywhere, but; the Internet is just Facebook now? I'm not hardwired to play online games, but they do make our bodies release dopamine and cortisol, even though we're not hardwired for it.

So maybe the future is indeed that we learn to take the internet for what it is: a fantastic tool for disseminating information and doing business, but nothing more.

But we're not hardwired for that either. How is that application good? Shouldn't we be transmitting information in form of songs, as it's natural?

So the challenge will be to give people meaningful ways to interact with each other in real life now that the human component has been taken out of things like education and shopping.

When was the human component taken out of things like education? And did the introduction of the web really remove a meaningful interaction, or did it just free up time that can now be spent with e.g. your family instead of with salespeople? Because that's my (anecdotal) experience.

Amazon's scaling of the AppStore to business is brilliant. This will bring the SaaS to small companies.
Thanks. I'm not sure that manifesto is being a thing that is overlooked; but regardless of it, I've been feeling the 501'er mocking others around for a while, without a manifesto being published at all.
Exactly the point, you can drink in a "cultural" way. There are actually very different drinking cultures. (As there may be different programming cultures?)

Drinking can even become a bad habit. Or someone can become an alcoholic and could still see it as a culture (read Charles Bukowski.)

A culture in any case is something very artificial and not very well defined in most cases. Everybody can simply declare to be part of a certain culture or redefine his own culture at any point. So now there is a 501 culture...

I think a culture is surrounded with some kind of related passion.

501's passion is to get back home. I can respect that, but it has nothing to do with programming.
As I've noted, imagine for a moment that they're talking about fishing. Their points remain valid to what they're seeking.
However many link it as a manifesto of programmers.

Its the same as publishing "Do no harm" as a manifesto, and it has nothing to do with programming, nonetheless a programmers culture.

Question of understanding: If what you say is true, and it actually does take up to three days to transfer the securities, how can you immediately sell an asset that you just bought a few minutes ago? My understanding of HFT (including from your description) was that this type of thing, i.e. holding an asset for only a few minutes, happens all the time. How can that be possible if the transfer takes as long as you claim it does?

That really isn't unheard of, you know. It isn't common, but it happens often enough that you shouldn't be that surprised. If you are shocked by people marrying at 18 I recommend you avoid looking into teen pregnancy rates.

Many early marriages fail (but then again so do many late ones, so that generalism might be based on confirmation bias) but some people are mature enough to have a solid relationship and life plan by that point so getting married early works for them.

Anti 501 Manifesto
No, that is a misunderstanding. What gp was talking about was a government surplus, which means government spending (investment + consumption + social) is smaller than government revenue (taxation). So in fact, with the kind of government surpluses that some (horribly misled) people are demanding, money will be sucked out of the private sector which will ultimately lead to less economic activity than otherwise.

There is no sense in which the government can save money like you and I, because the government is the currency issuer. It has an infinite stockpile of potential money anyway, adding to that stockpile is entirely useless.

What have you done?

Basically - pretty much the exact opposite of what you've done :-)

I had an idea some time back. I went and found some users first. Then I observed what they did and what they valued. Then I changed my idea. Then I went and observed some more. Then I changed my idea again. Then I went and talked about the idea to a group of folk that I was 90% certain that I was solving a problem for - and they mostly liked it. Tweaked the idea a bit. Went back. They loved it. They told their friends. And they pre-registered. Based on word of mouth.

Now I've got to the point where I can build something.

I know I have probably a couple of hundred users who are keen on the product. I know that they're keen enough about the idea to recommend it to friends. I'm not entirely sure whether they'll be entirely profitable or not - not sure yet. The only way to find that out is to build something (or the quickest and cheapest way anyway).

The point I'm trying to drive home is that having a way of getting to users is a core part of your business. It's not something that you should wait to figure out until after you've built your product (because figuring it out may well affect the way you build you product).

What would you recommend in my shoes?

Find a group of users of your product that you can contact directly.

In real life - face to face.

Preferably find a sub-group of your market that is most passionate about whatever problem it is that you're solving. The ones with the most pain, or the ones with the most to gain.

Talk to them one-on-one, encourage them to use your product. Watch what they do. Where possible tweak the product to support that group in a total wonderful way.

Encourage testimonials and references (any forms of social proof that you can use before you get large numbers).

Encourage the people using your product to invite other people who will use the product. Look at the way FreeAgent and Rackspace referrals work for example.

Be prepared to put a lot of effort in.

In my experience getting actual real users is a long, hard slog that takes time and effort to pull off. Unfortunately I think you're actually at a disadvantage now by having a fully formed product without users - because you may find that the "generic" product that you have now is harder to pitch to the smaller market that might have pulled in your initial early adopters.
Anyone have any idea what is amazon's cut from sellers?
Basic auth has no logout feature as far as I understand it. 123-reg tries to hack on something which looks like a logout feature but isn't.

For the point I was trying to make, it was the perfect example. It demonstrates that you can use basic auth, have "working" authentication, and be a successful website.

Note, the comment I was replying to was that basic auth is "unusable". 123-reg clearly disproves this.

I hate those. Unless you're familiar with the whole team you don't know who qznc is. Git/hg/svn blame will tell you that more precisely. Inserting your name in the comment is only slightly less annoying than people insisting to put "author"comments on top of the file (or even a function)

I think and I maybe wrong, what they are after is the API design and for fragmenting the most fundamental thing that Java was based on - Write once run anywhere - as Android can't run what's was compiled for JVM.

As for me, I just am frustrated that Oracle might have a good case.

We use Qlikview at work and SQL Server Reporting Services. I'm not clear on what exactly you are trying to do but Qlikview could be worth a look. There is a full featured demo which is only limited in that you can't share your documents with others.

Two neat features of Qlikview are that it compresses everything into memory (depending on the data up to 100:1 compression) so it is quick to manipulate your data. The second feature is that it links everything and you can change your filters on the fly. The net result is that you can explore your data on the fly and get instant feedback to your filter changes.

I too have spent quite a few years working in this area. I have primarily been involved in building tools to make this kind of analysis easier - but it is very difficult.

As you mention, the primary issue is that almost all business data is very complex. There are very few areas (in my experience), where simple queries offer much value, because there are so many niggling business rules that lead to exceptions and counter exceptions to rules.

This means that "self service" analytics are pretty much impossible. There are often very few people in an organization who actually know how to define even seemingly simple measures like profit or revenue.

This means you need consultants who can learn the business rules, and who also understand the data platform. This makes these projects expensive, and makes it hard for platforms to win in the market.

For the most part in my experience, the best way forward is to choose a database engine (MySQL, Postgress, Oracle, DB2, SQL Server), get the data into it (itself difficult!), then write a bunch of SQL to incorporate the business rules. Then if you are feeling fancy (and still have budget!), built a nice HTML front end on it.

Its not very sexy, but it does work. I would love it if there was an easier way, but I am yet to find it.
