1) What do you mean? It depends on field, but in most mathematical papers I read, the ideas are explained with words, not with symbols -- they only serve as helpful shortcuts. Anyway, I believe that properly used symbolism usually clarify the issue at hand, especially when word explanation is very long. For instance, what is faster to read and comprehend:

http://mathbin.net/62276

or

"Let V1 and V2 be a subspaces of W, such that their intersection is zero. Let f be a mapping from a direct sum of V1 and V2, such that it takes a vector, whose first component is x and second y to a difference of x and y multiplied by two."

And this was easy example, I can think of _a lot_ harder.

There is no regulating body of mathematical notation -- it can be (and usually is) created by introducing it in some paper or book by some mathematician who invented it and regards as useful. Frequently, there are more than notation introduced, but usually only one survives -- hopefully the best one. The only possibilities of encountering several different notations in use at once are either reading very old works, which is not good anyway, or the most recent ones, but I presume that people who are able to read them are also able to get over such a minor problem.

Seriously, I believe that the mathematic notation is a lot clearer, more intuitive and easier to understand than syntactic rules of many programming languages, for instance C++. Symbol overloading almost never pose a problem, since the intended meaning is usually obvious from the context. If one frequently misunderstands the intended meaning, it is a sign he does not really get the concepts involved, and the fact he is confused by notation is his smallest problem.

Even symbol overloading most often takes places only if the sign represents the same idea in all contexts. For instance, one usually uses '+' sign to represent a binary commutative operation whatever structure we all talking about, because, well, it represents similar idea. One can go even further and say that symbols like \oplus and \times in most contexts they are used in (Cartesian product of sets, direct product/sum of rings/groups/modules/vector spaces/mappings) are actually representing exactly the same idea -- namely, the notion of product/coproduct in some category.

There are a lot of different symbols in use in math. If we abandoned symbol overloading, we would need to introduce many, many new symbols, and this would create real confusion.
For the ability to watch them on demand, rather than via DVD through the mail. Netflix streaming is increasingly not available for popular new releases. This is like the Google equivalent of iTunes's movie and TV rental offerings.
Try http://grooveshark.com?
Netflix is going to have a tough time going forward - I've noticed that their instant streaming collection seems to be pretty stagnant. Studios are probably reluctant to give them their AAA big-budget titles for streaming. There's an awful lot of content I want to watch that isn't streamable.

Though Amazon VOD is cheaper than this price point. Wonder how Google will justify this.
Any info on where to buy one of the hardware kits?
this use of the word relation has fallen out of favour

Do you think that's true everywhere or just in web development world / MySQL world? I'd always guessed that, say, Oracle professionals know and understand the difference between "Chen--E/R model" and "Codd--relational database". But I'm not part of that world so I don't really know for certain.
bringing back some bad memories. I was forced to learn Morse code in the Navy and to type it at 20 words per min, and write at 10 words per minute. I have been trying so hard to forget it, and now all I can hear is long and short tones in my head.
as does rdio.com (pure streaming service). One of the features I like about both.
I enjoy using mongo / other document stores, but this article is lame. The contrast is between a single document storing an order, with sub-documents containing details, versus a table per sub-doc type. They claim you have to denormalize data in the relational version, which isn't true, and use that claim to assert that updates are complicated.

Guess what? Denormalizing data can make things complicated in mongo-land, too. This isn't just a relational db problem.
For any communication tool to be successful it has to be cross-platform. You aren't going to use an application if you can only talk to people who are running the same app on the same OS as you

That is why I agree that both Apple will eventually release FaceTime on Windows, and why Microsoft will do everything they can to keep Skype multiplatform
Nice !!! really cool site and free service!! Amazing!
My MBP has a 120 GB solid state drive and a 1 TB media drive. I partitioned 120GB from the media drive to do Carbon Copy clones so that it has self-contained redundancy.

I do incremental backups on demand with Time Machine.
min.us is awesome! I love the ease of front end facing interface and ability to just drag files and send out the link. I think that's the biggest differentiator from other file sharing services out there.

I can definitely see min.us replacing yousendit and other services of sort.
Faster than CPython maybe, last time someone did a benchmark of Go vs. Python webservers PyPy came out on top.
Given this is at Moscone -- anyone know what data links Google brought in to support the event?

Also - I wonder if they brought in WAPS from Ruckus Wireless this time - or are they sticking with Meraki?
If that were true, wouldn't the same apply to resource competition between groups of humans?
To a certain extend, yes. But then again, it is not so much about mathematic accuracy as it is about 'sounding good'. Many of the most successful audio effect devices have really meager processors. Careful tuning of simple algorithms is often more productive than crazy mathematical forays.
(This is kind of the same thing that applies to Openoffice and MS Office: OOo is not really technically any worse than MSO, but MSO just has the nicer presets and that makes all the difference).

That said, you are often limited by available processing power and micro-optimizations can be important. Calculating dozens of filters for dozens of channels on one DSP can be quite a challenge and getting that right algorithmically makes a big difference.
You probably don't. Not every service is made for every (potential) customer. Rdio/MOG/Rhapsody are for a segment of music listeners that like music enough that they are willing to pay ~$120 a year for unlimited streaming but not enough to have the really obscure tastes that those services don't provide. Google Music, Amazon MP3, MP3Tunes and other "locker services" are for people who want to stream their music, but don't buy enough to warrant a monthly subscription.
I am a huge fan of rdio and use it daily. However my collections of live shows and misc stuff will never make it up to my rdio account as of now. Thats a +1 for a music locker service.
Have been using it since is start, bloody marvelous! :)
Amateur Telescope Making
you need a bit more criteria.

if you want performance, an EVO will work well or an STI wagon

if you want a bit more luxury G37/Acura TL/TSX

if you want the badge, BMW 328i or C300

based on the Civic SI being your old car, the STI wagon would probably be your best bet...plenty of power and utility.

or

you can go used, and buy something a bit more exciting: last generation MB E63 AMG, E60 BMW M5, Audi RS4 etc.
Or you can use shift+insert.
I assume both Amazon and Google want to acquire the licenses to do what Rdio does, but what they do that Rdio doesn't is allow you to play songs that aren't licensed for streaming services. Also, they playback your songs at whatever bit-rate you uploaded them at (which might be consider a negative when listening to music over a cell phone network).
I haven't started writing any code yet, but I'll get to it eventually here: https://github.com/cfinke/Telegraph.js if anyone is interested in following the project's progress.
Sony's Decade of Woes
The evolutionary baggage is most definitely not one of cooperation, at least not beyond our immediate "monkeysphere"; millennia of wars and massacres bear witness to that. The primary reason we usually avoid violence is not that we find it irresistibly repugnant, but because we've become intelligent enough to realize it normally creates more problems than it solves. AI not being human (for some definition of human) also means it doesn't have to be jealous, hateful and short-sighted.
The whole intro talks about you, and what you want, but not what value you offer to employers.

Ask HN: contract work
im considering some contract work... i have a special skillset, and the company that is offering the contract will pay ~68/hr.

The median in my area is roughly $45/hr.

It's an interesting position in that I'd be speaking directly with customers, while also doing integration of systems, as opposed to just being an in-house coder.

Is there a reason that I should be wary of doing contract work? Is there a reason why this contract is willing to pay so much more than a regular fulltime position?

Ultimately, I'd like to start a company, and this could be a good way to build capital, and control the amount of hours that I'm working as well, so that my work time doesn't bleed into the time I want to have for startup projects/ideas.

What's your experience with contract work?
This represents an intriguing intersection of two big tech trends.

I'm teaching an introductory Arduino workshop at OSCON (O'Reilly Open Source Convention) again this year in July. Last year at OSCON Google had a big Android workshop, I'm curious what impact this announcement will have on interest in the Arduino workshop.
That web page links to this for "buy the hardware components": http://www.rt-net.jp/products/rt-adk

Though with machine translation I must admit I'm at a loss. Maybe they presume 3rd parties will step up to sell them on their own?

Keep it vague and remove words?

I used to do that with all my resumes actually. Concise and to the point. Though as I went further along, I started hearing what HR reps looks for and what Recruiters want. They want people to explain more about what they have accomplished. I figured to separate things by knowledge of a certain subject then push it out to what I have built, instead of saying what I built then and what Tech Ive used. Sadly, Im in a bit of a classified environment. So its harder for me to explain my actual work and much easier to explain the tech used.
I'm getting "Bad Request Error 400"; anyone else?
I would love for them to integrate podcasts with this. Google Listen is great, but is definitely showing its age.
Maybe; eBay paid $2.6b in ~2005 (OP says 3.1b, WP says $2.6b), and then sold off 70% of it for $2b (http://en.wikipedia.org/wiki/Skype#History). OP doesn't seem to specify how much MS is buying, but let's assume 100%, so eBay is selling its 30% too; 30% of 8.5b is $2.55b, so eBay sold its 2 chunks for 2+2.55 or $4.55b.

That represents a profit of 1.45 or 1.95b over 6 years or $320m a year. (If MS didn't buy eBay's share, then they are currently at a 0.6-1.1b loss on their Skype investment excluding whatever that 30% is worth.) Presumably eBay had better opportunities for 2-3b of capital.
There's a link on the site: http://www.rt-net.jp/products/rt-adk.

The site it links to, however, is less than useful for English speakers. (I think the site might be down under the load? I've been getting intermittent errors.)

Supposedly it's available immediately...
Google I/O 2011 Keynote Wrap-up
Can you clue me in? I just tried several a couple of weekends ago and it didn't work out. Twinkle was good but hasn't been updated for years and doesn't work with PulseAudio. Everything else barely ran.
This is not completely true. Modern calculus (and generally, mathematical) notation is a result of many, many years of evolution. Leibniz's notation only barely resembles the modern one.

I'm not sure what I was supposed to see in that link, but I already figured that Audiogalaxy ran as a service, and that's not the problem. To clarify, I meant that I want to be able to have an app (not necessarily Audiogalaxy, just something similar) where I can input an address for a service on my computer (IP:port or URL), and log in directly to the service without going through any other servers (except DNS) at any point in the process. Nothing against your product, it's just how I prefer to do things. I don't even mind that much having to make an account to download the software since it's still in beta; it's just that since the music is already being streamed directly from my computer I'd rather have authentication happen there as well. I realize that an average user probably doesn't care, but I do.
A non-technical user of this hypothetical iOS app won’t be able to tell if the author had to do some clever algorithmic hacks to get an acceptable level of performance, or if s/he spent a whole day figuring out how to work around an undocumented bug in some versions of iOS, or if the whole program is really a mountain of kludges that will cause endless pain to the next coder who tries to add a feature to it.
I am very surprised this is the first time someone try to get everyone's attention on this practice (if that's the intention of the poster/submitter). It's quite easy to spot recently there are well-timed attacks on Google or Android which are oddly fueled with passion. I suppose any money spent on this (which should be significant) would be way better used if it's used to improve whatever product the client have in competition with Google, really. End users, ultimately, won't benefit from these.
Link from the documentation: http://www.rt-net.jp/products/rt-adk

The site was down before but seems to up again now (it seems like the page was also empty the first time I looked--guess they just made it visible).

I'm not familiar with the company.

From the documentation it seems like a standard Arduino (Mega?) with the USB Host shield will also be compatible--depending on memory limitations.
I know nothing of this incubator, but I've heard that banks often ask for personal guarantees. There are various cases I've heard of where the business has failed and people have lost their homes, which were used as guarantee.

It probably comes down to what can be negotiated and I think it's mostly the same as you describe in Germany: Liability is limited unless you agree that it is not.

As a side note, I've had personal experience of one fund which hoped to get back the money given regardless of success or failure. I declined to get involved with them.
Comparing long term performance of git vs hg
Google's announcing something about music on the cloud this month. Related?
Ok, here's some more info... I want something practical with a little power, maybe more than a little. An EVO is definitely in the running, my co-founder used to have one of those (until he crashed it into a wall at Infineon). Don't care about the badge but I do care that it has three seats/seat belts in the back.

Be brief and say what you want.
I had a different problem, I found that word density increases 10 fold, but symbol density and proofs go down as you go through it.

My favorite example to use is this: Complex Variables and Applications by Brown and Churchill. This book has been in print for 70 years or something, and it's somewhere around 400 pages in the current edition I believe. My professor I did research for had a early 80s edition, and it had almost 100 less pages than the current edition. There wasn't really anything new added between the versions (chapters are only about 5-10 pages, so there's something like 65 of them) I ended up using mine for the problems and his for reading because I have ADHD, and the wordiness absolutely kills me. Symbols and relationships are much more meaningful to me than words describing them. The real nightmare with the ADHD sets in because of the break in context when you have to switch between two or three pages to find the next theorem, formula or proof.

I retook that class twice.

On the other hand, I utterly and completely rocked my Advanced Electrodynamics course, outscoring even the graduate students, in a course which even made use of the stuff we were learning in Complex Variables (as well as PDEs and all that fun stuff) Why? I had a crazy russian professor who hated all the current textbooks (I'm looking at you, Griffiths) for the same reason that I hated textbooks, too much words and not enough symbols. So he wrote his own notes to every lesson and made his own homework. He said he originally wrote those notes when he first came here, and his english was worse, so there's little or no explanation, just proofs -- math and symbols. A few of these would span two pages, and very rarely three, but there wasn't the context break you get in many college level books, just beautiful math and lots of intermediate steps. The intermediate steps, almost never provided in most textbook proofs, really help the visual learners like me and provide stepping stones for the inevitable manipulation you will perform with those equations in your homework and on tests.

I still have all his notes, I want to bind them up some day when I get a chance.
Yeah, total straw man. For e.g.:

Similarly, the order lines don’t contain product names, but rather foreign keys which point to a product table

Well, the product name could be the foreign key. Or it could not be. If you have 2 different products with the same name (or 1 person with 2 different names) then you have some complexity. Doesn't matter what kind of database you're using.
Are Android Movies lower quality than those available from Youtube Movies?

Many people are really bad writers. Further, many people are really bad readers. Restricting yourself to email with someone who functions better on the phone or in person is just asking that relationship to collapse. At some point one of you will take something the wrong way, or write something the wrong way, and you'll just get deeper and deeper resentment and other fundamental causes of relationship dissolution.

If you're working with someone who doesn't "get" email, even if they think they do, you do everyone a favor by manning up and calling when you have to and meeting in person when possible.
I just weighed in on this in a slightly different way... how to email people for the first time: http://chriscoyier.net/2011/05/04/how-to-write-an-email-to-s...
Google has far more sensitive information on me than Facebook. Facebook only has publicly facing information, stuff that you've already shared with other people.

Google has my searches, and what I've clicked on. And good luck trying to get them to forget those logs.

Funny you should mention that.

I've been interested in that concept for a few years--the idea of "craft consumer electronics": small run, customised to a particular niche that isn't viable at large volumes.

I'd be really interested in finding people who were interested in exploring this area. I've had some conceptual thoughts around solutions but nothing concrete.
As a former founder and now VC, I am thrilled about this post. It's so true. There is nothing I like more than learning about startups and helping entrepreneurs and founders. If that wasn't the case I would find some other line of work.

That's why I'm so sad when people view my inability to get to email in a timely fashion as a proxy for my interest or the type of person I am.

I just get a ton of email and it's impossible to respond to it all, much less in a timely fashion. I'll try my best to get to it all, but if for some reason you haven't heard back in awhile try again and again. If nothing else I'll notice your determination and provide some feedback.
I wasn't thinking of using them for speculation. I don't consider myself nearly skilled enough at that. I was thinking of using Bitcoin as an alternative to Paypal and other online payment systems. Unfortunately, the lack of Bitcoin to US Dollar conversion sites puts a big obstacle on that use.

It looks like this is still going to be limited to HTTP (port 80) web applications.

So you won't be able to run a process like Doozer that communicates with other ports/protocols.

EDIT: More details from the docs at http://code.google.com/appengine/docs/go/runtime.html

An App Engine application cannot:

-write to the filesystem. Applications must use the App Engine datastore for storing persistent data. Reading from the filesystem is allowed, and all application files uploaded with the application are available.

-open a socket or access another host directly. An application can use the App Engine URL fetch service to make HTTP and HTTPS requests to other hosts on ports 80 and 443, respectively.
How did you conclude "loan is to the business - with limited liability, you don't have to pay it back if the business fails." from "will only look for the loan to be repaid when it makes sense for your business. This will be done on a case-by-case basis."? I won't.

It just means, they rather discuss the terms of loans individually, on case to case basis.
