Hmm. Would this mean specifying similar amounts of context? Japanese from the little I know, at least when spoken, omits a lot of details that can be inferred from the context. I would imagine casual speech to be far more efficient than polite formal writing, which includes many details that would otherwise be left out and uses the longer "polite" verb forms.
I can't understand the point you're making here. Earlier, you suggested ALICE SELL @ $10, BOB BUY @ $10.05. Those orders can't rest in the book; the match engine will evict them immediately by executing the trade. The is no time interval between Bob's order and the trade execution.

Could you perhaps explain the specific scenario you're talking about here? Alice, Bob, and Mallory perhaps?
It’s amazing to realize that it took only five years for a giant like Nokia to become irrelevant in the market. That says a lot about the competitiveness and the speed of progress in the computing world.
I work on optimization software and I'm pretty sure you could do some serious damage to the government's tax collection efforts if you hooked up a genetic algorithm to some very good accounting software to minimize taxes.

The problem with GA's is that they frequently exploit loopholes in their setups, so you get solutions that technically satisfy your evaluation criteria but it's not what you really want. This process is basically what corporate accountants do manually to get ridiculously low tax rates for big companies. Congress writes the tax code but it will always have loopholes, and GA's will definitely find them.

Here's a recent blog post of mine that goes into some of the problems with GA's, which when you're looking for loopholes is actually a huge advantage:

This is exactly what HRBlock and Intuit currently do. They have hooks into all the payroll processors and investment companies and will download your W2s and any 1099s from the relevant company. Then you just answer a bunch of questions.

The problem is that a private company shouldn't have to offer this service. The government should do it for you for free because it helps them get their money faster and easier. However, as the article and others noted, those private companies realize this would be very bad for their business and have lobbied to stop it.
I'm pretty sure Intuit lobbied pretty hard to kill any and all progress that would allow most people to have their taxes automatically completed for them, equivalent to the 1040AUTO mentioned in some of the other comments.

But tax expenditures are the only way for anti-government types in government to spend money! ;-)

The complexity doesn't come from the simple cases: it comes from the cases that are legitimately complex. Carried interest, investment gains, charitable contributions, foreign income, corporate debt and so forth aren't reducible to a simple equation. For the vast majority of Americans taxes are simple: for many of the rest, they will never be simple unless they are abolished all together.

Collaborative filtering.

I use S3 and EC2 interchangably when it comes to EMR, which is what I presume is what the author is referring to. Most EMR jobs consume and write their data to S3 and use a temporary HDFS cluster for scratch. By and large scratch data ends up being much, much larger than the original inputs, if for no other reason than that needed during the shuffle/sort stage. (I am assuming we are talking about non trivial map reduce jobs here, not word counters, where you have many reduce steps.) it goes without saying there are many applications where user-created functions will generate more data than they consume (combinatorics, etc)

Data locality is but one reason to use map reduce. In practice EMR allows you to draw upon elastic computing resources to allow you to process data however you like. It provides developer and cluster isolation and linearly scalable I/O from S3 as well. The author sounds like someone who may have read the academic papers and a few books but hasn't used these tools in practice.

1. What deductions? I fill out a ton of them every year and they're never more than my standard deduction. Maybe things change as I get older, but in the meantime it seems like a safe default. "Do you want to try and get your taxes lower than $X by filling in a bunch of info? (Y/N)"

7. Yeah I think most of your objections apply to the minority of people who actually hire a CPA to do their taxes.

The bottom line is, for the vast majority of people (even people with interesting W2/1099 incomes like me) you could do your taxes on a napkin if you enjoyed a bit of paperwork/math pain. Again: the IRS already has basically all of this info. What gives?

The Museum of Modern Betas: VERSEU
I don't classify myself as a 501 developer. I'm probably the opposite that they're rallying against. But I don't dismiss 501ers. Two things strike me from the manifesto.

Since I've become a parent, I've noticed 5:00 has become more important to me. We put our kids down to bed around 8:00, so I only have a few hours of quality time with them each day.

Secondly, there are just things you won't learn on the job. And that doesn't mean it's a bad job. My new shiny is currently Haskell. I shouldn't get huffy if my work doesn't allow me to time to explore it. It'd be nice, but I'm not entitled to it. And further, it doesn't mean I should start hunting for a "better job". So in my opinion, 501ers are left with three alternatives:

1) They only learn/play/explore things that apply directly to their 9-5 job. Or are limited to whatever time their work allows for exploration.

2) They find a job that aligns with their interests.

3) They make an business case to the company to incorporate the technology. (However this is best done after you have a level of experience with it)

People could argue which of those are better. But if you're someone like me and like to play with a large number of technologies, sometimes removing the job out of the equation is much easier...and maybe even more fun.
3rd year university student's opinion:

The first problem to be solved is that most introductory math education is still about calculating and not about applying mathematical principles to real problems. I think that being able to estimate a solution is a valuable skill, but for many problems with a high degree of precision (lots of decimal places) or large numbers, this just becomes problematic.

I'll definitely admit that at the end of a string of transformations of complex numbers, integrations, and other things, the last thing on my mind is guessing whether my solution is close. Understanding all the steps that lead up to that point is more crucial (and worth more marks!). The only thing I worry about is whether I typed the equation into the calculator correctly to get my final result.

That being said, when students are first learning about a new 'operator', like when learning division, multiplication, logarithms, and exponents, this could be a useful tool for enhancing a student's intuition about how that operator works. But after that, I'll stick with a normal calculator.

"We’re sorry, but your Gmail account is temporarily unavailable. We apologize for the inconvenience and suggest trying again in a few minutes."
It's only a partial outage (Google says 2% of users - much lower than I suspected).

Mine's been down for about half an hour (I'm in the UK). Someone did an Ask HN where it was mentioned that #gmail was trending on twitter which suggests that the problem is widespread. Edit: it is trending on twitter in the US at least. I didn't bother checking other locations.

I suppose one doesn't need to make the obvious observation that Google are of aware of the problem:

1. Funds of actively traded securities are nibbling away at you with or without HFTs. Actively traded funds are evil.

2. HFT market makers aren't nibbling at actively-traded funds. They're nibbling at other market makers. Like I said previously: an HFT market maker is bidding the price of liquidity down, not up.

3. Your 401k is almost certainly not invested in a fund whose strategy is passive trading and selling liquidity. Your funds have positions in the market. Passive traders do not take positions. Your 401k benefits (very marginally) from the tightened spreads created by HFTs. The people who don't benefit are day traders.

4. I have no idea what "strip clubs" and "blackjack" have to do with any of this.
He is- looking at his blog he actually submitted a YC application:

If WP7 fans are anything like us WebOS fans, you're probably right. But who says it's too late for Microsoft? When DOS (and more importantly, Windows) came about, Apple was already the established king of its market. It could happen again, right?
This also implies that Google has private fiber between their data centers, right?

Maybe it's because RavenDB is a document database as opposed to an OLAP database (I'm assuming that's what you refer to when you say billions of rows with wide data and not another NoSQL like Mongo). Indexes and data arrangement between the two types are not an apples to apples comparison.
I think you will be interested in the design of the Macintosh video/audio hardware, too, then; http://www.folklore.org/StoryView.py?story=Sound_By_Monday.t... gives some details.

IIRC, things were even better. There were two (740 byte, IIRC) buffers from which samples were taken at every horizontal refresh.

The sound driver used one to get samples to send to the speaker; the disk driver used the other to control the rotation speed of the disk drive (using pulse-width modulation).
Here's the thing though: ostensibly, financial markets aid in allocating capital for real world investment.

Real world investment doesn't work on a millisecond basis. It doesn't even work on a per-minute basis - at best, it works on a daily basis.

So if we were talking about how the financial markets benefit the real economy, we would say that Alice wants to sell at price X on Tuesday, and Bob wants to buy at price Y on Tuesday. And in that case, the go-between is unnecessary.

Nobody in the real economy needs instant order fulfillment when even regular bank transfers take a day to clear.

I get that more frequent dealings can help with finding "right" prices. It certainly reduces the spread. The problem is that HFT makes market access unequal.

You claim that Alice could have held out for $10.05 if she had wanted to. This is incorrect. Alice most likely does not have the infrastructure in place, and the fixed costs would be far too high for her to participate in that game. So in fact Eve did not provide any kind of useful service to Alice. Eve exploited unequal access to the market for her personal gain.

From a libertarian perspective you may say that's fine, granted. But the argument that Eve provided a service to the real economy is not as clear as you make it seem.

So there is a tradeoff there. HFT reduces spreads and perhaps helps price finding. However, for most market participants form the real economy, intra-day fluctuations dominate the spreads by orders of magnitude anyway, so reducing the spread isn't even that much of a useful service to the real economy - at least not to the extent it happens today. On the other hand, HFT makes access to the market unequal, limiting market competition.

It seems unlikely to me that the current situation is a proper balance within this tradeoff.
I'm sorry, could you clarify who "Subby" is or what you did?
Well, borrowing idioms does not make a work non-original and non-copyrightable. The philosophical/legal point Google is making is that no language (computer or human) is copyrightable because it is not well defined: it's a moving target.

OTOH, I think the main issue here is not whether or not Java the language is copyrightable, but whether the Java APIs are. I have no clue as to the legal thinking underlying this question, but my hunch says that APIs should be copyrightable.
Yes, their trades are for much bigger amounts, and they also don't pay the hefty brokerage fees that casual investors like us pay. One example, http://en.wikipedia.org/wiki/Direct_access_brokers which cost around $0.004 per share. And maybe HFTers don't even pay that much.
That would be a really great strategy. I love the pricing style of prepaid plans, but the phone selection is horrible. I always end up unlocking a smartphone and hacking it onto a prepaid plan.

If Microsoft could also make data more available/affordable for prepaid plans, it would definitely be a hit.

It seems like a good time to reflect on the concept of The Cloud. I run my mail off a 400MHz Pentium 3 in my closet, which would scale up to (probably) a few hundred users, enough for the companies of most of the people having problems here.
I'm not sure I like overloading the term jitter in this context. The title made me assume they meant packet jitter, aka the standard deviation around packet delivery times, which video is sensitive to when not taken into account. This is a similar concept around cache and resource access times, but a desirable property rather than a something to deal with or eliminate.
The tax system is not convoluted and complex due to the influence of the tax preparation industry, they have very little influence on the matter.

Instead, it's the way it is due to many other enormous industries and interests (farms, welfare, support for families and home owners, investors, etc, etc, etc.) I can guarantee you that the reason there's a special section for "fishing boat proceeds" on your W2 is not because H&R Block thought it would be a hoot but because of complex politics around the fishing industry.

> We take a competitive 20% of sales

That's actually pretty high in terms of BTC markup. There are BTC payment solutions out there that take less. Is the proposed value-add here a kind of content discovery service a la App Store?

> pay in 48-72 hours

Surely this can be optimized? 6 confirms is the standard of trust even for enormous transactions, and automatic payouts after such a threshold are simple to implement (yes, I've done it).

The time lag seems kind of artificial here and brings to mind the BS of traditional banking/payment processing. Is there some reasoning behind it?

> We're looking for feedback on who to approach for supplier relationships, startup mentoring, and funding.

If you'e looking for funding, you're going to hear this a lot: "seems more like a feature than a product". It's too early to be thinking about investments.

Is the idea to become a general for-download BTC marketplace? If so, you're probably doing the right thing in terms of going after the small / independent fish first. Find some sort of niche and eat it. Start worrying about investors when there's so much demand that you can't handle it on your own. You seem to be managing well enough so far, though.

Congrats on the launch!
Sorry, subby is slang for submitter. I am the developer of the linked site.
If Eve had taken the day off, Alice would have traded with Bob, and it would have looked just as immediate to both of them.

This comment makes sense only in the context of a message board hypothetical, because it presumes foreknowledge on Alice and Bob's part. Here, Bob showed up. Eve looks like a genius. But it was equally likely that he wasn't going to show up.

A lot of the discussions about liquidity and HFT here seem a little innumerate. They appear to work from a scale where the hypothetical Alice's ask price is "absolute zero". That's not the real scale. Obviously, instead of Bob showing up at $10.05, you're equally likely to end up with Chuck at $9.95.

If you're not equally likely to get Chuck instead of Bob, why are you selling?
