Ah yes, AC motors, the bane of most of the EE's in my graduating class since computing electromagnetic fields in a rotating context was such old technology. At the time the only 'use' for them was machine tools and blower fans, both of which took advantage of the fact that you could plug them directly into a 3-phase power line and they would run at 60 RPM all day and all night.

Variable frequency 3-phase inverters which can support the current capacity to generate 100HP+ (75KW) was really only invented with iGBTs in the last couple of decades. The article doesn't mention that the inverters have to be cooled, as they are a significant source of heat as well.

Yes but incompleteness refers to things that are true but can't be proven to be true.

I think you're referring to the idea of prospective axioms which can be proven to be independent of existing axioms (notably the axiom of choice). This is another thing altogether.

In the end, knowing enough about something to reduce it to axioms is only the start and not the end of understanding. P = NP wouldn't suddenly trivialize the problems so much as indicate that a polynomial time solution exists somewhere.
You can write object-oriented code in assembly language too. I've done it -- it's fun and it works great. It was well suited for writing video games in the 80s.
Ah! But you see, it's possible to trick CPython extensions into thinking you do support refcounting: http://code.google.com/p/ironclad/ is proof. So you can be compatible, yet advanced :)
Yeah that's what I get for being in the OOP world for the daily grind. I think a C API is still definitely for the best. Perhaps a nice shortcut API for this would be something like:

response_complete(200, body, response_header("Content-Type", "text/html"));
"I work in the pet industry"

I think that is a key factor in your experience, I for one would feel the same way.

I think most people would choose hardware based on App availability. So, for baseball, absolutely. The iPad has a better tablet version of At Bat 11.

In more general terms, I'm still figuring my use patterns out. I've had the iPad since it came out in Mar 2010. I've had a Xoom since the WiFi model came out in Mar 2011. To be as objective as possible, I'd still tell my non tech savvy friends and family to go with the iPad. The whole experience (not just hardware specs) is smoother.

Right now, the Xoom is fun, but a lot of what I use the iPad for is not available yet. Netflix, Hulu, and Zinio are all either not working at all or require hacks. I thrive on figuring out how to make that stuff work, but my parents do not. Since this is a post about MLB, I'll leave my deeper thought on the subject for a later post.

Yes, except Mozilla have to yet to show that it can be done. They are yet to understand that IndexedDB does simply not provide enough low-level primitives to implement SQL let alone have even a chance of coming within 10 orders of magnitude of the performance of SQLite.

There's a design flaw in IndexedDB, namely IndexedDB does not regard objects as opaque. This is the first thing you'd need (followed by variable length records) if you wanted to implement SQLite on IndexedDB.

And portability. And being reliable/known. Which is why militaries require large amounts of fossil fuels for now.

I remember when I was in the Army that our 5-ton dump trucks had lots of onboard stuff running off pressurized air, presumably making the vehicle more durable to electrical failures

Combine with local stored fossil fuels, and basic mobility/counter-mobility, and you have a harder-to-cripple ground force.

To be clear I wasn't talking about humor in media - of which there are a lot of excellent examples, but the amount of humor that seems to be part of day to day life.

Incidentally, I wouldn't regard Monty Python as being very representative of "natural" British humor - I'd probably suggest Al Murray in his "Pub Landlord" persona to be far more like the comedy you are likely to encounter in real life (or Frankie Boyle for us Scots).

Sorry for being a little harsh there.

At the height of British occupation , there were not more than 1700(!) British people at the same time on the Indian subcontinent. Which itself is a fantastic testament to the British Raj's bureaucratic machinery. The English education was an instrument in creating that machinery.
When 'Status'es on FaceBook became automatic Wall Posts, and therefore persistent, I commented to a few friends that this one simple change altered the nature of Facebook from a social facilitator to a social inhibitor. Before, if you wanted to know what your far-away friends had been up to, you had to call them up or send a letter, forcing some level of social interaction. Now you just have to dig through their wall posts.

It was once nice, simple, succinct. A 'phonebook with pictures.' Now, it's sterile and noisy, and not even useful as a phonebook.

[Edit:] This persistence of data I feel drives and encourages the issue the author describes - friending people you don't know just to see what they're doing (and to gain access to their photos, et cetera). There's a simple and obvious solution to the 'complete strangers' issue, but I don't feel that is the real problem.

Yes but it's an actual "homeland security" issue that we don't own the resources in our own country that are critical for our future infrastructure/transportation needs (vs. the theater issues at the airport).
If you do not friend people you aren't friends with, you do not have this problem. For real friends who are annoying on facebook, that's what the little 'x' is for on their updates.

I imagine it's harder if you're even just a little bit internet famous, but most people aren't.
Wow. Aside from the fish, that is exactly the story from my father's side of the family.
Also interesting is their capability to produce their full Torque output at 0 RPM. For applications requiring high torque for "station keeping", this is crucial, and is pretty unique to SRM (Switched Reluctance Machine) motors.

I've been quite interested in repurposing the little Dyson "digital motor", but I suspect that a complete drive system redesign would be necessary to enable full variable RPM control (ie. 0-max, in both directions).

Question for turbofail: did your project happen to use the SRM motor from the Neptune front-load washers, or some other motor?
The question marks seem to suggest that you're poking a hole in grandparent's argument, but it seems like you're both in agreement that the shootout is misused. What am I missing?
Asking "what's an ebook cost" is too wide a scope. It's like asking "what's a physical item cost?" It's unsurprising to find a large range. When you narrow the search, you find established values. Digitized classics go for $0.99. Novels are about $9. Textbooks are similar to their dead-tree counterparts, at $60+. Serious reference works can be thousands.

Run of the mill technical books clock in in the $20 to $40 range. I'd aim for that, and go high or low within there. And as a new author covering a widely-known process like agile, (opposed to the landmark work on a popular language), low would probably be best.

How much the book saves a business is immaterial. If it's a truly academic, novel work, you might justify a premium. As it is, you're hardly the only person writing about agile.

Ask HN: What do you do when you don't have an itch to scratch?
So the saying goes that if are hunting for ideas about what to build, that you should scratch your own itch. My question is, what do you do if you are unsatisfied with the solving other people's problems, but don't have an itch of your own to scratch?

I have build a career out of scratching other people's itches. I've gotten away from the daily grind to a good extent by going independant a few years ago. In the end, it is still largely unsatisfying. It might be that I have been doing development for so long that I lack the foolishness or innocence necessary to accomplish anything on my own. When I have an idea, my brain is to wired to think of all the reasons why it wouldn't work, or that it would take to long, rather than possessing that go-go-go attitude.

I think what it boils down too is that I feel I have the skills and experience to accomplish just about anything, but lack the passion for any particular problem or idea.
Not mine, but....

Very cool. I was surprised at how much little code is needed to make this work. After reading through the source, it seems like no js lib is "needed" for this effect to work at all. The rumble.js file might be a tad bit longer, but no need for an external dependency.

My suggested approach assumes hash as a baseline approach (identify actually identical files -- which DropBox is apparently already doing) and goes beyond this (identify files that are identical in source and intent, but different owing to random trivial errors).
As a designer, when an org comes to me and says "we have $[laughably small amount] to spend on this website", I point them to WooThemes and tell them to pick one out. I'm happy to sit down with them for a few hours and do some basic work, but put the burden on them. It works great for me, because I get to do a little design education, still get paid, and focus my time on more lucrative projects. It also can pay dividends when clients come back to me later for more work or other design changes.

To put it in a more uncouth way, 99Designs and WooThemes take the pain-in-the-ass clients and get them out of the way. I don't see it as a bad thing. I just wish I had come up with the idea first.

I feel as though, like Digg, this is going to be an astonishingly effective mechanism for getting Kevin Rose attention.

And probably not much more than that.

What mystifies me is why he doesn't just focus on the thing he's good at: being in the spotlight. I think Digg made pretty clear the fact that he's just not the guy you want doing the day to day, tedious, mostly obscure work of running a company.

Which is fine.

Maybe he could go to acting school. Or do a vlog?
So 10 super ninja rockstar pirate devs? They build out awsome ideas, sell them and move on to somthing else? Never keeping a product long enough for it to implode?

I guess he was serious about what he learned at Digg.
That implies some global state somewhere being updated, and now you've given up on threading. This may be OK, but it's still dangerous and leaky even if you give up on threading.

There are various solutions that still allow you to pass a set of closures without being particularly more ugly than anything else is in C, for instance, see http://library.gnome.org/devel/gobject/stable/chapter-signal... . C++ still ends up nicer, my point is just that you can do good things in C and there are libraries that implement the stuff for you.

That said, if I were really going this route I probably would try to go with some sort of minimal C++. Then again, my opinion is suspect, as I would never go this route anyhow. Web developers writing in languages that don't permit buffer overflows write software that has all the security of a colander; adding the ability to write good, solid buffer overflows as well hardly seems like a step up. You can write secure C code, but you can write secure PHP code, too. Existence proofs of secure code aren't very interesting.
I'm kind of bummed that someone who can't comprehend my post got upvoted way more than I did.

It's hard to guess what the world would be like with no patents, but I suspect at minimum you'd see a lot of obfuscation, such as drugs with impossible to identify active ingredients and devices designed to be impossible to figure out or repair.

Well if he has money to spend, actually this may be the best approach for him because he is a nice guy but not a tech visionary.

Bringing together a group of smart and talented people and let them experiment with little apps and see what catches on may be the best way to come up with a successful product.

Also, lets not forget that we live in a time when the 'coolness' of an app makes a it a company, not its revenue.
Sorry, small clarification:

Houdini is actually descended from the PRISMS package developed by Omnibus Computer Graphics (one of the very first CGI studios (and actually still in business in Japan!)). SideFX (started by two of the original programmers) bought the rights to PRISMS when Omnibus (North America) went under. They opened for business in 1987 and have been going strong since!

They have a number of "firsts" to their credit -- for instance, Houdini was the first major 3D package on Linux. Debuted in 1999, although I was beta-testing it before that.

For procedural 2D and 3D graphics, there is absolutely nothing like it. However, it's hard for most users to understand, so its popularity has never been great. Anyone doing serious FX work knows all about it, however.

(My old boss used to be CTO of Omnibus, in charge of PRISMS development.)

> The "gateway interfaces" for C are too implementation-specific (CGI, FastCGI, SCGI, web server extensions/modules, etc). It would be something more abstract that would run on-top of a web server interface.

Yes. My preference in web apps (esp in C) is also to deal directly with http requests and responses. Although I wouldn't necessarily call that the "more abstract" approach. To an extent, each of these gateway interfaces is a different leaky abstraction for http.
"I know the right way to use this code and I have thought of all the possible use cases. If you don’t agree, then you have to prove me wrong and wait until I either agree or figure out a better right way for you.
This is the real message developers hear when internal code is private scope or marked with the final keyword – a message that they have arbitrarily limited power and ability to make changes where they need to. But it doesn’t stop there."

Maybe I'm missing something, but I kind of agree with the (italicized) straw man argument the article is trying to refute. My private implementation details should be irrelevant if I give you a public API, and it's likely that I have thought it through enough to tell what'll be useful. Furthermore I can change the implementation without breaking you. If you need to muck around with the private implementation details, there's something missing from the public API. What happens if the original author wants to change the implementation later?

Hiding the implementation details just seems like reasonable encapsulation to me. Is there something specific to the PHP world which places less emphasis on this than I'm accustomed to?
I wish this had cicadas!

The main problem this person faces but glosses over is the fact that they've added people they don't know. Why do that? It makes no sense and will only cause you to get annoyed.

I am quite proud of the fact I only have 100 FB friends, because I know each and every one of them. I lot of people I know from IRC and work refer to me as the Facebook Nazi because I won't add them, but they're not really my friends and I don't want to know what they're doing at 5am in the morning.

Toughen up a bit, delete those people you added because you know a tiny bit about them and things'll become that much easier to deal with.

This is exactly like the "Oh I get SO MUCH email" posts and then you find out the person signed themselves up to 50 email lists, 20 "email me when you get a new comment/status" things etc. Don't sign up for crap you don't want, it's that simple!

[Edit was just spelling fixes]
Just as Mark Zuckerberg and William Gates.
A lot of scientific code also runs on the (crufty, spiffy) Matlab, which is fast but not super-fast, is less portable than most things but has good usability and lots of history.

A python that could run incrementally, with robust threads, in the ground might, just possibly, make SAGE a better environment and so increase migration from MATLAB (my personal scientific computing experience was with Matlab and anything that escape this monster is great in my book).

I mean, Python won't become faster than optimized C so however convincing or unconvincing the faster iteration and usability argument is, that, in the end is going have to be what Python makes.

People who believe that they don't have time to read are fooling themselves. The real problem is that they find it increasingly difficult to concentrate amongst the distractions that a lot of us have allowed into our lives. The solution is not more technology (or smart services like this one) but rather a significant change in our lifestyles. Training yourself out of the ability to concentrate will have serious long-term consequences as you grow older and those who seek to invent great things will find it hard to do so without deep thought.
