It's actually much broader than just flash trading, essentially you can divide it by which part of the bank it occurs in. Any front office tech (risk management, pricing, analytics, trading) app tends to be on the competitive edge as does anything it relies upon (infrastructure, feeds, tick databases, etc.)

Back-office technology (settlement, reconciliation, etc.) tends to move much slower.

It also depends on the asset class, more stagnant areas such a mortgages tend to have more stagnant codebases than "hot" areas like FX.

Competitive areas aren't the same across all firms either, while one firm might put a lot of money into it analytics technology another might ignore that area altogether and just buy in an off-the-shelf solution accepting that it's not going to compete in that area.

Essentially the only way you'll know about the quality of the tech you'll be working with is to be smart and ask questions at the interview stage (this is true for any firm).

5 Reasons An Angel Investor Will Walk From Your Deal
I think it's a trade off of having a decentralized system vs. a centralized system. Just imagine if we could only use Gmail or Facebook for email--now that would be just plain scary.
Even so, more input fields means more visual complexity. I suddenly feel like I'm at the DMV.
I don't really remember but when it appeared there was an option button/link and I followed it and one option is to switch off the sidebar. Never use messaging really.

Looking just now I have the old style tab, if I click it the sidebar pops open, there's a "cog" for settings in the bottom right corner. IIRC you have to set yourself as "unavailable" to all and then use the cog to select "hide sidebar". Try that.
I would change it to:

Indeed. I don't think anybody is benefiting. Quite the opposite. Software patents are seen as just a bunch of land mines that make it harder to get the job done. There is no thought of making use of them whatsoever.
I feel that movie idiocracy (http://www.imdb.com/title/tt0387808/) had a potential to convey this (although the execution of the movie was bad). The idea of the movie also had to do something with numbers. I believe that is why most of the religions of the world preach to have more children so that they can have strength by numbers.
That's better, but I still don't like it because you're forcing a relationship upon the user, regardless of whether or not they want one.
Reducing every angle of a story to a single thread isn't going to help matters.

To take this week's AirBnB PR uproar as an example, many of the front page posts on the issue represent different facets of the story. Sure, only one link to the original blog complaint from the renter is necessary. Subsequent posts highlighting the story's path from HN to TechCrunch to a TechCrunch-hosted official response to the Financial Times and other news outlets are providing useful context here. The story has moved beyond the facts of the initial incident and onwards to its impact on startups, fundraising, disrupting regulated industries, and more.

There's a lot to talk about here and it doesn't all belong on one thread.
I think articles that are not the original source should be merged as comments under the original source since they are often just another news organization or blogger commenting on the source without additional source data.

This will also bring Hacker News more in line with paragraph 5 of the Hacker News Guidelines[1].

I believe even if an article "adds to the conversation" it still isn't worthy of a top level submission. It should be a comment like all the others.

EDIT: To implement this maybe power users above a certain karma threshold can be granted the ability to mark an article as derivative and point to the original source submission. If some magic number of power users do this, the article and the comments are moved and any links to the derivative article are redirected as well.

This will also discourage karma whores and blog-spammers from submitting derivative articles because there is a good chance it will get rolled into someone else's submission that actually submitted the source article.

But would you consider that 'recovery' or 'discovery'. To me, recovering passwords means applying an operation to reverse encryption. Brute-forcing passwords is simply guessing, which makes it a discovery.
You shouldn't do anything because sometimes you may get an update on the story and the discussion could be totally different.

Not a hack, just pointed at the wrong thing. It's an 'under construction' page in Japanese. (The second line says 'this server is under construction.' Don't know why they didn't bother translating it, too.)

Intel can see it. The development of the Atom was partially a reaction to ARM. Intel is in a classic innovator's dilemma and unwilling, apparently, to pursue the most successful strategy to counteract it - create a standalone business entity that can and will compete at the smaller scale.

Many of these articles then extrapolate the ARM X86 battle into the server space - which does not follow. The mobile disruption is that smaller devices will replace laptops and potentially desktops with newer simplified usage models and not that X86 will be wholesale swapped for ARM in every case. Cloud computing does present though a separate potential to disrupt server X86 that companies like Tilera are pursuing.

Does this graph take interest into account?

For instance, if the deficit was one trillion dollars at the end of President Smith's administration and two trillion dollars at the end of President Jones' administration eight years later, how is the blame apportioned between Smith and Jones? A large fraction of Jones' deficit is due to the fact that he's stuck paying the interest incurred under President Smith. So a fifty-fifty assignment of blame is wrong. On the other hand, we can hardly absolve President Jones for his failure to pay off the debts incurred by President Smith, either.

Of course, as DanielBMarkham has said, the whole idea of blaming presidents for deficits is rather silly, when it's really congress that writes the budgets. (Not that presidents can be absolved of blame either...)
Certainly the experience is inconsistent and something I'm willing to accept. Considering the amount of experimentation on implementation and the rapidly changing OS, I will tolerate bad eggs to spoil the bunches. The problem is not with the software but with how Google has handled it's branding of Android and the "preferred" experience it associates with it. "with Google" was suppose to solve this problem, but as you point out there are still issues and loopholes.

I bought the MyTouch3G (2nd Android phone ever), the G2, the Nexus S and recently the Galaxy Tab. Overall, I'm very happy with the experience of each of these phones. There are other phones out there that have great experiences as well. As a consumer, I will research these purchases which matter and will pay with my time to get exactly what I want. If you want to, instead, pay for one company to handle quality end-to-end for you, then you will pay for that, too.

For me, the pluses in Android outweigh the (few) minuses (that remain).

For anyone else, it's great that they have the choice to make. :)
There will be a JTAG port, so there may/should be the option of some very basic I/O, but not to the arduino level as far as I can tell.

Ask HN: Hacking Piano Learning
Hello Everyone,

I have been part of HN community for over 2 years now and I really love learning from all the smart folks who hang around here. I have decided to learn to play Piano and I would love to know if my fellow hackers have any tips. Here are few questions I have:

1. Can I learn it on my own from the online courses OR should I get a teacher? [Time is a problem for me, I doubt I can get a teacher to teach me at 9.30pm.]

2. Any Piano learning course you guys recommend? I have found that Rocket Piano and PianoForAll are quite popular. Any experience with them?

3. Has anybody tried Piano Marvel software? http://www.pianomarvel.com/ The game mechanics built in to the software appeals to the geek inside me.

4. In my research, I came across http://www.pianofundamentals.com/. The author (Dr. Chang) claims that the popular 'Hanon' practices are not very useful. He also claims that learning using his method is 1000 times faster than other 'regular' method. Any experiences in this area?

5. Finally, I want to be able to learn to play by ear. Any good material on how I can achieve that? [Or am I toast because I am starting this at the age of 30 and not when I was 10?]

Thank you in advance for all your inputs!
I feel like this problem is bigger than just Hacker News - with the plethora of different news/discussion sources,I often find that 'breaking news' gets old and stale within an hour of the event. Or, sometimes more damaging, I read an interesting comment, then can't remember where I read it (so I can properly cite another's analysis).

Sadly, I don't know there is a site specific solution. While a merge would theoretically be great, I think we would start to see super threads with several hundred comments (and associated repetition). The search feature would be interesting, though it would discourage extremely busy people from submitting (since you could theoretically have to read three or four articles to determine whether yours deserves to be a separate item).

Perhaps some sort of curated site that grabs content (complete with discussion) from around the web? Different take on a newspaper's editorial section...
It seems that it should be possible to 'force' certain libraries into the compiled js, and then do a 'dumb' non-optimized eval. Yes, you get a bigger js file than if you just stuck with dead code optimization, but having access to the full library at runtime is the entire point.
Your point 1 is exactly the question I came here to see answered. The article actually claims "Another benefit to unified text fields is getting the user’s information in a format that you want without sacrificing ease of use or speed" - but I want to be able to use the forename only (so, for instance, I can address newsletters with Dear Jacob).

It's certainly not about validity / invalidity of names. And yes, that's not a perfect situation - some people may prefer Dear Mr Aldridge or Dear Jake (ugh). But as long as I recognise that shortcoming, and (which I do) only require a single name (so people with only one name are not ruled invalid), I don't see how a unified field gives me the format I want.
As grist to the mill, another example:

Yeah. It's important to point out that the bison sources are (apparently) available under the GPL. They're just not distributed with emacs, thus the distribution is in violation. The broken headlight analogy is a very good one. This is a bad "oops" moment. It's fixable via some elbow grease, better organization, and probably a review of a process or two.
Cue GOB's "I've made a huge mistake."

Unfortunately I doubt we're going to see RMS on a Segway.
Not sure if the article's been edited, but it now refers to the mouse using crowd (for whom this change is even more beneficial).
We should be able to link stories together. The most popular/recent story should then be shown instead of all of the others... (But you should still be able to visit the others if you wish to.)
Last I looked, both Chef and Puppet were meta-tools that launch all the other third-party tools I don't want involved. Are either of them solid enough now to actually replace the system package manager? Can they answer questions like "why does /etc/foo exist, which package created that?"
Turn HN into twitter (sans 140 char limit). Posts are "unstructured", bit do retain @reply information. User @a and @b posts a link about Airbnb, user @c wants to reply, says "@a @b what #Airbnb really needs to do is bla bla bla.."

Then, the front page becomes a list of "trending topics".
Topics are determined by some kind of statistical analysis of the overall conversation.

The /new page is a list of new posts that are not @replies, or something similar.

Order/score can similarly be determined, such as by reply counts.

More computationally intensive, but more "true".
> Money going to the government to "fund programs" doesn't go into the economy either.

It most certainly does. The government doesn't hold any significant amount of money in reserve. Every dollar they receive (and a lot they don't) gets invested in the economy in some way (salary, materials purchases, R&D, etc.)

> When money goes to "private accounts of executives", and those accounts are in banks and investment funds, that money is going to be used to capitalize new growth (unless they're hoarding that money in Swiss accounts somewhere).

This is a lovely dream with little evidence to support it. The idea that rich people getting richer helps the economy is not founded on fact. There's been a tax holiday before. It didn't grow the economy. Tax cuts for the wealthy did not grow the economy. Even if wealthy people invest more when they get wealthier, the real issue is whether that is more valuable to the economy than more dollars flowing through the hands of most people, more dollars flowing into infrastructure investments, etc.
The ambiguity lies in the word 'unreadable'. The key phrase is 'unreadable... using strong cryptography'. Can strong cryptography be reversed by decryption, or is strong cryptography a non-reversible hash?
I think that's different than what the OP is talking about though. If different stories are providing updates to an earlier story or original information of some other kind that's fine. If there are multiple links from different sources that are duplicating the same basic information then it creates unnecessary redundancy and splinters the discussion.
Isn't this an obvious thing to do? I'm quite surprised it hasn't been implemented anywhere yet.
He's referring to the finger pointing / blame shifting that seems to happen whenever someone starts criticizing desktop Linux. Any time this comes up people pop out of the woodwork to give the solutions, sometimes of staggering complexity, to the specific user experience problems cited.

The reality is that Linux-the-umbrella will be judged by any specific distro's user experience. People more familiar with the situation will know that in many cases bad experiences are caused by choices specific to distros or even the packages they bundle, but the true average user's perception is not that nuanced.

The same argument largely works for Android. In some ways worse because there is a certification process that allows you to use the Android name, but does very little to ensure someone didn't wreck the user experience with their customizations.
A README isn't source distribution (though I suppose it would constitute a "written offer to provide source", which is allowable under the GPL). And it can't be retroactively applied to versions of emacs that are already distributed.

The goof here isn't that emacs is somehow "polluted" going forward; everyone agrees that this is easy to fix. The problem is that existing versions of emacs were/are distributed in a form that is a violation of its own license.
Absolutely actionable advice for Airbnb.

Screw business, if this happened to my clients, I would go spend a week with her, try and help restore her life back, be on the phone for her with credit agencies, police, lawyers, anyone.

Isn't that the reason why we start companies? To make lives of others better? Do you need better examples to drop your stuff and go help others?
You don't need to build a big app with lots of features to make money. That's the wrong lens to look at it through. You need to build an app that solves a big problem. People pay you based on what solving that problem is worth to them.

In Patrick's case, BCC solves a problem that is worth more than $30 to his customers. It turns out, making bingo cards by hand is a pain in the butt.

You asked for some other examples:

- http://audiomixology.com/ - The problem is "I want to learn to be a bartender". The perceived cost is the cost of bartending school, which is hundreds of dollars. This site has rotted since I first spotted it, but I think the price was $79. And the product was basically a set of mp3s with mnemonics to remember drink recipes, an iphone app that present those same menomics (and maybe a flash card system), and a couple ebooks. This guy was definitely making money and had written a few blog posts about his process of developing Audio Mixology on http://muselife.com though I can no longer find them...

- http://onswipe.com - these guys have gotten funding and a lot of press recently. However, I think they started as pretty much just a wordpress plugin that made your wordpress site look better on an ipad. And if that isn't what their mvp was, it still sounds like a legitimate mvp to me:)
My point wasn't that this device would defeat them, but that it's possible to make computers that are this ridiculously cheap. Add a little more horsepower you've got a serious competitor... And it should still be pretty cheap.
This is an open/closed debate, nothing more. The OP likes closed systems. "I’d love to see Google somehow mandate the stock Android experience on all phones." He is afraid to customized his stuff and just wants it to work out of the box. Well, that's what Apple is. Go do that. Android is a different model entirely, for a different segment of consumers than yourself.
As far as I understand it, the "no punitive damages" is a huge difference.

"private accounts of executives" is an interesting phrase when you cold have said "checking accounts of employees". It conjures up the image of Scrooge McDuck sitting on a pile of gold.

But that money is in the economy. If these "Executives" put it into stocks, then it funds company growth. If they put it into municipal bonds then it funds cities. If they put it into a checking account, then it funds home loans. IF they were to turn it into cash and put it under their mattress-- then it still funds government spending (via inflation.)

The only possible way I can think of to take that money out of the economy-- and granted this is even if your assertion that "all the money" goes to these fat cat "executives" were true, and I'm not buying it--- the only way they can take the money out of the economy would be to buy actual physical gold bullion coins and put it in a basement.

So, if these guys really were like Scrooge McDuck and literally had a basement full of gold coins then it would be out of the economy. But that is pretty much nobody.
The identity/trust set of problems was solved long ago by hotels and most other businesses: when the customer arrives you meet him, check his id, get payment info and show him his room. You can take pictures of him if you wish (e.g., security cameras in the lobby). A check-out process should also occur.

The AirBnB contract should be between rentor and owner of rental property: AirBnB's participation should be only as an agent. That limits liability and makes clear what is expected of each party.

IMO AirBnB should not be responsible. This is looking more and more like a shakedown of AirBnB or preparation for a lawsuit.
BTW She is making more damage to the AirBnB employees (and their families) than the raiders did to her.
I'm so excited about this. I want to get one for my 8-year-old nephew -- does anyone know of any good simple tutorials / manuals for linux for somebody just starting to program?
It's a £15 (GBP) device. Does that mean it'll be $25 shipped??

Technology/Gadgets are usually quite a lot more in the UK than the simple dollar conversion.
I'm slightly concerned that AirBNB are spinning this rather than just sorting stuff out. Veiled threats to the victim, whilst spreading incorrect stories are a concerning development in an already distressing case. If the guy in custody is the guy responsible, why are AirBNB and EJ not in sync? This smells massively of a total PR disaster for AirBNB, whatever is said about compensation or no, threatening victims, or telling them to 'limit access to their blog' is as naive as it is stupid - how does the internet usually react to 'limiting access'?

I do hope ST2 gets a better Mac icon for its final release. The big straight-on square doesn't look good; it needs a bit of perspective. Valve's Steam (which on the whole is very un-Mac-like) made this correction.
Often, you have to have a first name and last name due to various business / legal constraints. There is no way around it, even though, as you've correctly said, not everyone has a first name and a last name. Unfortunately lawmakers are often not culturally sensitive enough to understand that.
Wonder how feasible it would be to have a similar device that you could cluster by simply direct connection, modular computing anyone?
Research firm IHS iSuppli recently said it projects that by 2015, 22.9% of notebook shipments worldwide will be ARM-based systems.

22.9% for an estimate four years away? Not 23%? Impressive accuracy :P
