Wow this essay is totally off track.

There is no such thing as a "market price". To prove this to yourself, write a simple model of the stock market with buyers and sellers. Every order is a limit order.

What is the "market price"? Is it the last trade? Is it a weighted average of the last 10 trades? It doesn't actually exist.

At any price there will be a certain amount of liquidity. If you want to guarantee that you can buy a lot, then you have to pay extra b/c the counter party doesn't want to sell low so he hedges by adding a bit of spread.

The same applies to selling. If you want to sell a lot you have to discount a bit b/c the buyer will want a bit of insurance that he/she isn't overpaying.

The HFT algos do add liquidity b/c if the liquidity were there at the first price probed, then the algo would never really matter, the desired shares would have changed hands with some other counter party.
Anyone who calls fb credits a "tax" knows nothing about payments. A ubiquitous payment system where users are already authenticated could easily double conversion rates once deployed at scale.

I admit having the data online is potentially more far reaching.

Much, much, much, much more far reaching. Isn’t that exactly the problem?
Yes, but it is so hard to tell the two apart, especially when you are talking about someone a lot of people have strong opinions about.
Theories on why 5-HT2A agonists (most psychedelics) do what they do
If course the HFT trader wouldn't sell unless it could profit by selling. They are HFT traders, not market makers.

Obviously if you are buying shares sold by an HFT trader, you are not buying them from a market maker, so you are getting a better price than the market maker is willing to offer.

I'm sorry, your question wasn't specific enough and I thought maybe you weren't familiar with the concept.

I have no idea how they plan to build their network, so I can't help you with that.
Was I able to figure it out? Sure. But did I have to pause for a second to figure out what he was saying? Yes.

Proper punctuation makes it much easier for readers to read and comprehend the material quickly. If you don't believe me, try reading a paragraph with no punctuation at all. You'll spend most of your time trying to figure out what words are grouped together because there's no punctuation to clue you in.
What if the manual-save stopped working and didn't tell you?

I suppose it's equally as likely. The example I'm thinking of is losing your network connection while typing an e-mail in GMail. It shows a warning message, but out of the way so you might not notice. If you intentionally take an action to save, you are more likely to notice the result (and a good user interface would make a failed intentional save obvious by a popup message or something).

You made a change - that's it. You don't save your paper after drawing on it with a pencil, do you?

Depends. If I was drawing something remotely important, there would probably be many revisions, some of which I'd want to keep, some of which I'd want to throw away. Some of which I'd want to make a separate copy of to work in a different direction. So yeah, versioning. How do you version things without files?
Fascinating. I had no idea that government regulation is the force which drives companies to stop manufacturing products which are expensive to manufacture and for which there's little demand in the market. You've truly opened my eyes to this hitherto-unseen lurking evil.

When did "confirms" become a synonym for "says for the first time"?
With realtime multi-person editing and operational transforms showing up in Google Docs my guess is that there's a decent amount of cross-pollination going on there.
Personally, as a programmer, I have concerns about hooking anything resembling an autonomous computer system up to anything important. The stock market, weapons systems or large industrial systems like oil refineries for example.

Any time you take the humans out of the loop you're playing a dangerous game. All software has bugs. All software fails in weird unexpected ways at the worst possible time. When its software that has significant real world consequences like influencing the markets, firing weapons or operating equipment that could kill human plant operators and making decisions at speeds that make human intervention difficult or impossible you're asking for trouble.

Bad sentence. It implies that Asperger's is a derogatory term.
The platform for decentralized sharing of private data has already been built. It's called HTTP and PKI. Glad to see that they're using this as their core.

However, they need to immediately purge from their presentation any ideas of "server" or anything sounding so hard for an average joe.

I realize it's just a start, but if v1 doesn't have a "click here to start your private seed" that's hosted on a cloud somewhere they are going to have a hard time growing.

Yes, it is 1.4 times the deal people had, if and only if the conversion rate goes up that much. Whether the terms will change or not in the future is also something that a businessperson would consider.

P.S. Yeah, I know the mathematics above isn't exact if there is already a fee for transactions, etc., etc.
> Your comment is full of the absolutisms and blanket assertions that I'm talking about.

The question isn't whether they're absolute, it's whether they are wrong....

> Regulation IS systemic risk. -- Always?

Yes, always. Regulation enforces common behavior. If that behavior has bad consequences, its effects will be more widespread than behavior by a company or two.

> Doesn't really look like they needed a lot of encouragement from regulators to me. I don't think you're telling the whole story here.

I'm not telling about all the things that regulators got wrong, but I'm accurate about the things I do mention.

And yes, they needed encouragement. There are lots of things that they could hold, but regulators wanted to increase the demand for mortgage-backed securities (because that lowered the price and made it possible to do more of them) so they came up with a number of financial rewards.

> How huge a hit? "We require a 1 trillion dollar bailout" huge? I don't think so. Red herring.

I didn't say that it was the whole problem, the mortgage backed securities that they held also lost a lot of value (see above), but it was significant. Fannie and Freddie lost $100B in market cap during the first 8 months of 08 and things haven't gotten better.

I find it interesting that you think that one aspect of the problem must be unimportant because it wasn't the whole problem....

Here's a question - what incentives to regulators have to get it right? Note that failures in regulation are typically followed by "we need more regulation", as you've demonstrated....
Honestly I thought it was just me -- I definitely did a double take in two different spots in the article.
That actually made me laugh!
Could someone explain: As a person who uses Apple products but doesn't code, what does this mean for me? Is Apple already using this compiler with OS X? Does it mean faster and smaller binaries down the line?

Or is it mostly cool stuff for coders, but mostly transparent for end-users?
Companies that I strongly dislike do that all the time. They sometimes end up great in terms of earning potential, but rarely are they the ones that I respect or admire.

I'd put a finer point on it: paid writing encourages the creation of content which appears superficially relevant (especially through the eyes of a search engine), but doesn't actually convey any substantial information.

I hadn't looked at Yard in a while, actually, but http://yardoc.org/docs/ruby-core is a pretty compelling example of some nice output, especially given that it's generated from the C code.
I'm in the middle of reading materials about system analysis and design, in particular about Enterprise Application Integration.

I took a break and checked out Reddit and HN. Stumbled upon this article and the GrooveShark AMA. I realized that these days some of the big websites are moving toward similar situation with that of a typical enterprise apps situation where there are different components/sub-systems written in different technologies. Is my assumption wrong?

Seems like between Enterprise App (whatever Enterprise means) and these big Web 2.0 apps, the difference is only in the matter of the users; the former is geared toward businesses where the latter is leaning toward customers/end-users. The technology obstacles are rather similar.
Introducing zPost: Zoho Invoices via Mail
Clearly, in his example, there are people out there willing to sell at $26.10. In the old days, you could put out an order from 100,000 shares, saying you would pay up to $26.40, and you would get most of these shares at the $26.10. If there were enough people willing to sell that many shares at that price.

Now, even though there may be people out there willing to sell you the shares at 100,000, these programs can find out your top price, and they will but the shares at $26.10, and sell them to you at $26.39, thus making a profit of the difference. Providing no extra services to you, or the market. They have just stepped in as the middleman with no risk.

This is how the article describes it, and this is how I understood it. Is this wrong? I think you are just arguing semantics about the term market price.
The Reddit comment thread has a few insights, but everything seems largely skeptical. What are the legal ramifications, if any, of using Grooveshark?

Somehow I doubt that teacher salaries were your only expense. I doubt that teacher salaries were even your only not-mandated expense. (As to "mandated", I've found that some of the "mandates" are an excuse. Yes, I've done this exercise before.)

Actually reading this I wonder why facebook gave applications the ability to collect email addresses easily? Lowers platform lock in as someone like Zynga if they do move away from facebook can just use the email to keep the user base they have acquired.

Why bother with a clear, elegant, cohesive design when we can create a device from the grab-bag school of engineering! I know I may sound glib, but these doesn't seem to be any real thought or reason behind this, just more me-too-ism
Well, roughly speaking, you can group Cassandra deployments in two categories+: new products that are hoping they need Cassandra's scaling ability someday, and existing products moving to Cassandra from something else because the pain of scaling something that wasn't designed to makes them.

The first category will start small. The smallest production deployment I know is a single 256MB VM, but usually even starting small you should not have less than 2 servers (why tempt fate with a non-redundant setup when Cassandra makes it so easy to be safe?).

The second group is where you see larger deployments out of the gate. 3 machines does seem small for reddit; I guess they made up the difference with memcached. Unfortunately they deployed just before the 0.6.0 final release was out, which is where we added the row cache feature that could have made memcached unnecessary.

+There are people using cassandra for non-scale-related reasons, though. Most of these people are motivated by multi-datacenter replication.
I often see this role filled by what everyone calls a "secretary" or "assistant". They tend to be very highly valued by everyone in the company [below exec level] and tend to go all the extra-miles to babysit same execs. Even moronic extra-miles such as re-booking hotel-rooms on a saturday because the CEO didn't like the furniture, or organizing company-events in their off-time because the CEO "asked" (read: demanded).

Sadly, more often than not, at least in my experience, aforementioned execs take all that for granted and the secretary remains a secretary in terms of pay and appreciation.

It's one of those stereotypes that I keep seeing over and over again that pisses me off every time.
I disagree, great designers innovate. You build on the shoulders of those who came before, but if you're not doing something new and innovative, it's not great.

The biggest example I have is Apple.
Are the shares worth 26.40? Then you should be happy to get them for 26.39. If they aren't worth it, then don't make that offer.

I don't see why you should care who sells you the shares. You either want them or you don't.
I think it's better done with spacing, as in "to-day - a good day - is the middle of the week", when you're not being anal enough to use &emdash; or Unicode literals etc.
Mahalo's not a business I can get excited about, but this Calcanis guy consistently writes extremely interesting stuff, has done huge things for entrepreneurs, and is prolific in ways that deeply impress me. Can't take that away from him.
Actually the numbers could be much, much better than 2X.

is very valid. In the case of payments, I'd bet for a conservative initial system that gets more flexible over time. The nature of anti-fraud almost mandates that approach.

No. It's only because we feel so much affection for Apple's products that their business practices provoke so much outrage. In comparison, when was the last time anyone got really worked up about Microsoft?

I think that it's actually the hydrostatic pressure at the bottom of the intake that pushes the water up, not the atmospheric pressure. Hydrostatic pressure is essentially only a function of depth: P = rho.g.h. Think about the design of a damn, it needs to be much thicker at the bottom due to higher pressures. You can experiment (or thought experiment) with two cups of water and a tube on the same level. Fill one cup and fill the tube. As long as the depth of one side is greater, and thus the hydrostatic pressure is greater on that side, the siphon will continue until the pressures equal. The difference in atmospheric pressures is almost negligible.
I wish I could. :)

All of the fascinating things about signals are confidential for all of the reasons listed in the article, and Google has been sued so many times by sites that think they should rank better than they do that I can't really give examples.

I think it's safe to say though that there are a lot of people worried about and thinking hard about what the web is turning into and how to rank it appropriately.

Most of the content is no longer written by devoted hobbyists, people no longer link as often to things they like, and much of the content on the front pages of reddit, digg (and sometimes even hackernews) was put there by people trying to make your search results worse.
I find Calacanis a bit annoying, but I think he's mostly right. Contrary to what Calacanis thinks, adding new features that let you compete with other apps isn't wrong. Its part of business. If they want to muddy the purpose of their product by adding 101 bells and widgets to compete with everyone under the sun, they sure can do it.

I do agree with Jason that Zuckerberg seems to have a questionable history of integrity...based on rumor. And I certainly agree that Facebook seems hell-bent on harvesting the souls of their users. The latter is far more troubling that any competitive feature additions.

Was the original facebook an innovative myspace/friendster?

We're reacting negatively to Facebook infringing on foursquare's turf because facebook is the bigger company.

What about bing? Now that Microsoft is the underdog they're a lot more palatable.
> I'm curious... why is it that so much antivenin was required? If that much is needed, why do hospitals only stock six vials apiece?

Because odds are they won't need it. They stock to buy time until they can get enough for a single patient.

To put it another way, if there's an average of one patient/year in an area with 10 hospitals, what's the right amount for each hospital to stock? Remember - they have lots of other things that they could stock with comparable odds.

> In other words, work produced by lonely geniuses is quite likely to go unnoticed.

I think this is something that has happened throughout history. The web probably makes it easier for the their work to be uncover than before but they are still at a disadvantage.
We were on stage at TC50 two years ago. We definitely were a startup. Like a good chunk of others, at least 30%, maybe half. I have to be fair to the selection process, having no funding was not a barrier to being selected. That's as open-minded as I can think.
This is great, but they only ran one test on the device, Linpack. Just keep this in mind, the phone will not be 4.5x faster, with the new OS.
The ethical issue is that someone is deriving additional profit through an asymmetrical advantage. It's kind of an interesting ethical question actually.

Personally it just feels wrong in some hard to define way to algorithmically determine the other sides maximum/minimum price through some process they don't have access to. I can certainly understand why you would do it but it just doesn't feel quite right.

I don't think I have an ethical problem with using small orders to sound out the other party. Where it tips over into being unethical for me is if those exploratory orders are cancelled rather than fulfilled. I'm surprised its even possible to cancel your offer once someone else has accepted it.
As you suggest, this is going to be a matter of personal taste. But to me, naming software after an oppressed people is prima facie gross. That kind of homage is patronizing by default. We don’t have a Jew filesystem or a Tutsi browser, however flattering they might be the minds of the founders.

I think it’s mostly irrelevant that Gimp is an acronym. As an extreme case, if the initials of my descriptively named project happen to spell the N-word, people would be right to question my taste if I ran with it. Obviously “Apache” is not the same as the N-word, but you can see the point. It doesn’t matter if the connotations in my mind are only wholesome: I’m assigning to symbols that are already bound in outer contexts, and that’s dangerous in human culture.

I’m not trying to be the political correctness police here. It’s not my job to get angry on other people’s behalf – I’m not Apache or physically disabled. But I would think very hard before calling a project anything like Apache or Gimp, and to me they seem at least as bad as Diaspora.

Anyway, I do see how a reasonable person could hold your position.
