What perplexes me here is the enthusiastic response received for the development and deployment of bitcoin mining hardware (for which the motive is giving a hardware edge to people in order to make lots and lots of money) versus the condemnation of HFT (for which the motive is giving a hardware edge to people in order to make lots and lots of money). Both cases require a significant outlay of resources and talent and I have respect for the work that went into each.

And this gets at a bunch of people, including yourself, claiming that HFT somehow defeats the "purpose of the market(tm)." But if I look this up on Wikipedia, I get the notion that it exists to help corporations raise money and secondarily to provide an indicator of the general economic mood. I fail to see how HFT goes against this. That said, I'd support everything Mark Cuban suggested short of the trading tax (because I believe (without proof) that it would have unintended negative consequences far beyond HFT).

Mark Cuban aside, I mostly see various people who, to quote an Amazon review of "Broken Markets: How High Frequency Trading and Predatory Practices on Wall Street are Destroying Investor Confidence and Your Portfolio", sound like the reviewer's grandparents explaining why they don't use computers. No hard proof - just lots and lots of fear-mongering.

So much so that I'm starting to believe that the underlying issue here is resentment and jealousy that they didn't pull these hacks off themselves and walk away with the big bucks.

Finally, how is HFT worse than the "good old days(tm)" where major brokerages all had seats on trading room floors from which they could manipulate the bid/ask spread with impunity? I'd counter that it's actually better now that anyone capable of getting the cash and talent upfront can get into the same game that's been played since the very beginning, except that the pace is continually accelerating and those left out in the cold are succumbing to future shock. Buffett knows how they'll deal with the events preceding an actual Singularity(c) if one occurs.

But that's just my opinion, feel free to disagree.

You're an absolute bloody idiot iff (programming joke!) you use dropbox for syncing your project files. Its not smart to use it as a repository because a change by one becomes a change for all. And of course its going to be taxing on the cpu, everytime you compile and test every file gets updated/recreated and dropbox has to work to upload the changes to the server. Why don't you try using a real versioning/repo tool like Bazaar or git or svn instead of the lunacy of trying to make dropbox get the job done. And you should have to manually do a commit at the end of the day because you need to document your changes if anyone is going to have any hope of picking up where you left off; therefore the argument that you would have to remember to restart dropbox is invalid. Why don't you stop being lazy and actually do your job?

My day job is working on an Android application with audio recording and I write games in my spare time, so I've had occasion to look at this. Android's audio environment is end-to-end poor, especially compared to iOS. The native APIs are pretty crude, there's bizarre latency all over the place, and the Java APIs are badly designed, poorly documented, and have absolutely insane failure modes.

Right now, I would recommend iOS (and I don't do that much) for anyone who is serious about audio programming on portable devices.
I like the concept and awesome for the fellow to release it... however in the past the following have seriously messed up any attempts of mine to get sensible autocompletion in vim: working in cygwin, projects > 2mil lines of code, and varying types of build infrastructures.

I am surprised to see so many people mentioning dropbox and git. What does dropbox add that you don't get from git?[1] And/or with git and a decent backup system(tarsnap/duplicity/rsync)? It seems like a lot of extra overhead and data privacy concerns for little gain. What am I missing?

[1] I'm not saying this because git is the magic fairy dust. Replace git with hg, darcs etc.
These goals, they are not incompatible ;)

Also, I'm curious as to which usurpations you are alluding.

First web 3.0 at scale? Possibly.
I don't think the jury has truly made a deliberation on web 3.0, but we think it's using data and machine learning to predict behaviors and trends before they happen. At scale. For everyone.

WhatsBusy has integrated to biz data systems and leverages data from outside the business to forecast foot traffic at venues - which it then shares with the public. Will doctor's office be busy next Tuesday at 3 pm? CDC rates, seasonality, and historical schedules from the doctor's office say YES.

March 1 will be a true test for web 3.0 viability. Launching with forecasts for 50,000 venues, including DMVs, museums and airport security lines, WhatsBusy is using big data in, our own biased view, a uniquely democratized and utilitarian way. Will it hold water? Sign up at www.WhatsBusy.com for early access. Is web 3.0 finally here?

Point 3 is extremely interesting. There is a lot of controversy going on about their sales tax collection[0]. I say that it is interesting because it gives an incentive to the customer to use their virtual money instead of traditional payment methods. Other advantages I see (or that you saw) only benefit Amazon, which only gets mild sympathies from most users. I am not sure this will have such a great impact however, because unless they find a loophole to sell those coins, the first sale would still be subject to any applicable tax.

While there's a lot of Minecraft that's certainly CPU-bound, rendering at higher resolutions has next to nothing to do with CPU speed. The bulk of your rendering work is done by the GPU, and the GPU in Ouya is more than capable of rendering Minecraft at HD resolutions.

I'm most depressed by the "fast forward to 2006" part of this article, where they mention 3-6 Mbps service being delivered.

Fast forward to 2013, AT&T will still not offer anything faster than 3Mbps DSL to my home, and they charge a princely sum for it.

I can get 30/4 from Charter for the price of that 3Mbps DSL, but Charter's customer service is so awful that it makes AT&T look like Zappos or Nordstrom.

That's a good point, but if that's the way their product ends up being used, the company is looking at a rough road. Obviously I have no privileged information on their operations, but the BOM for their console is not leaving much in the way of a profit margin on hardware. So I have to think they're banking on people buying games and making their bones off of that. If people use the machines just as emulator boxes, I would bet that the Ouya folks have cause for alarm.

They're giving away the razor here, and their blades aren't better than anyone else's.

If you want "proven" you should probably be using NodeJS then... not for GUI apps, but for headless apps and services... since it's core engine is V8, which runs on nearly a third of the desktops out there with far more regular use than Java. And the language JS, with more developers using it than just about every other language combined.

This is kind of tongue in cheek, but seriously... NodeJS is relatively new (since 2009) and it's gained a LOT of traction... it isn't the perfect solution, but then again nothing is. I like Mono and have used it, they've worked through a lot of the earlier issues, and it's pretty decent at this point... IIRC it's the core of the Unity tools, as well as having Xamarin tools available to support the majority of mobile platforms.

Can we really get mad at bad programmers?
> if I understand correctly there's no way to avoid an extra round trip?

With HATs, you only need to contact one replica for every key. This is to goal behind our definition of "high availability" (http://www.bailis.org/blog/hat-not-cap-introducing-highly-av...).

In general, I haven't seen algorithms guaranteeing serializability or atomicity that complete without a round trip to at least one other replica (or a possibly long trip to the master). Intuitively, the impossibility results dictate that this must be the case, otherwise partitioned replicas could safely serve requests. Daniel Abadi has a great post about this latency-consistency trade-off: http://dbmsmusings.blogspot.com/2010/04/problems-with-cap-an...
Don't forget to do a reconsideration request after you use the disavow tool. You'd be better off getting rid of the links, but that might be difficult.

Well, they just released the XPS 13 with a 1920x1080 display:
http://www.slashgear.com/dell-xps-13-ultrabook-full-hd-editi...
Dell has total assets of $44.43 billion. This makes Michael Dell's 14% stake worth more than $6 billion. That's what he's putting up. It is hard to see competing with himself as a reasonable course of action - even more so given that he would not be able to put his investment in Dell toward a new venture.

In other words, the $24 billion is there by virtue of the company being Dell and Michael Dell's participation.
If you are worried about cost, just run it on a subset of your servers. 10-20% of your servers should be enough to gather most information you need... unless you are using new relic as the only aggregator of server status/monitoring... and that should be heroku's job.
In the very first paragraph, the author derides people for not making these types of decisions from a mathematical standpoint. He then goes on to say that 15% of $125,000 is $25,000.
I would prefer the "wallet" method that steam uses. You require people put at least $5 in the wallet tied to their account. It's easy to remove the leftover balance because the first time you buy something over $5 it takes money from the wallet and charges you the rest leaving $0 in wallet.

I'm pretty sure they use Mercurial themselves.
Tesla's ingenious strategy
>Doesn't this make it harder to reason about cases where multiple userland threads need to mutate the same state?

Most languages make it very hard to reason about state in general. Haskell provides STM, so ensuring correct access to shared state is as simple as using an MVar. I absolutely agree that this is an important part of languages making concurrency a priority, they can't just add green threads and pretend that is good enough.
Dropbox disagrees with you: https://www.dropbox.com/tour/4

Note that I've been using DB successfully as an up-to-the-minute backup since it came out - it's only in the last week I've had problems bad enough to go back to my weekly backups.
Hello IE, it's IE calling :)
As a developer I only keep my source files symlinked to Dropbox, thus avoiding the problem of uploading binaries. Dropbox serves as a means to recover lost changes, should something happen between commits. There can be no excuse not to use backups and version control.

Nice. Real businesses need a data warehouse and SQL is the right tool for that job.

I thank them for releasing this.
I think this is really a competitor to something like Roku rather than XBoX/PS/Wii.

I imagine most of the buyers will be people who already have consoles or people with no real interest in consoles or hackers wanting to repurpose it.
This is a game changer, or at least a huge step in the right direction. I shouldn't have to wait for individual websites to make systems like this, third parties like Clef should handle it for everyone.
For about a year I worked from home and due to impending cabin fever I decided to give coffee shops a try. It was super loud and I always felt like I had to keep moving and buy something. It was just distracting.

I then rediscovered my local library and was amazed. Fast Wifi, Keurig machine, and private study rooms that I could take for the entire day. I was even more amazed at how many people use it as a 'co-working space', one guy would even come in everyday and even set up his VOIP office phone.
Presumably the difference is that you don't have to pull/push. Can't say doing that ever bothered me though.

Edit: actually it looks like most people use a bare repo on dropbox so you still push/pull from it. I don't understand the use-case at all then.

This is pretty cool but I'm struggling to see what the use cases are, atleast for analysis. There might be quite a bit of benefits for running application code that I'm not aware of. With regards to analysis though, their own example question is "what happened last night?" but then they go on to say that it is a near real-time data store. Does it matter that it is a real-time mirror then?

I've always liked the paradigm of doing analysis on "slower" data stores, such as Hadoop+Hive or Vertica if you have the money. Decoupling analysis tools from application tools is both convenient and necessary as your organization and data scales.
We totally agree. Having every site try to re-implement and keep up with security best practices is a waste of time, money, and makes it hard to trust anyone online.
That's great, but emulators don't pay the bills. (Which, to be honest, I'm glad for; making their bones off pirating other people's work would be pretty gross.)

I use LESS a lot; with my dual monitor setup I have my IDE on the the left and the browser on the right. If you add #!watch to the end of the url and refresh the page, it will poll any LESS file linked in the page once a second and display changes without needing a refresh.
There always will be a calculation that takes an absurd amount of time.
> Nobody adjusted the models when they produced incorrect answers because the answers weren't incorrect. They weren't the answers you like in hindsight, but they were correct insofar as the model was vetted & the input was correct.

I can't believe you are seriously arguing this. According to you, ratings agencies have no responsibility for the accuracy of their models as long as they fit historical data. By this logic, it's "correct" to rate Greek bonds at AAA right now because they have never defaulted before (this is a simple and completely accurate model that fits past data). Also see: http://xkcd.com/605/

Ratings agencies aren't paid to make models, they are paid to make predictions. When those predictions are wrong, it's on them. It's not reasonable to give a AAA rating that is based on an assumption that housing prices will rise at 10%/year forever, just because they have for the last ten years.

Rating agencies aren't paid to be a cultural zeitgeist that analyzes and summarizes the way financial markets are right now. They aren't paid to "go with the flow" and accept assumptions uncritically. They are paid to predict what will happen in the future, and to make especially sure that the most confident ratings (which grannies depend on to make sure they don't lose their retirement) are only given to financial instruments that make the most conservative assumptions.

I'm just astounded that you so freely deflect blame for this onto the public. I hope that this isn't the general sentiment inside the financial industry.
are you kidding me? There is absolutely NO reason whatsoever to use a NoSQL database for a financial services company. Postgres is more than capable of sustaining the necessary speeds of a startup.

Relational databases were created in the first place to solve these very problems around transactionality and analytics for finance.

This library is a beautiful example of reinventing the wheel, and otherwise creating a patchwork of unnecessary - and ultimately brittle - infrastructure.
This is very awesome, congrats Jesse and team!

It should be noted that SBC was one of the child companies of AT&T before their anti-trust breakup -- SBC envisioned a new AT&T taking over South Africa, and succeeded beyond their expectations (AT&T was broken up before home internet and DSL even existed).

Somehow, AT&T was allowed to repurchase SBC, so now it's just AT&T again.
The Death of XNA
A lot of things worry me about my daughter(s) and the technology that they use. It sounds like you take the same approach. I can't tackle each new app in a tactical fashion so I can only drive the 30,000 foot level stuff. "Would you be proud of this if someone else saw it? Do you think that's hurtful to other folks involved?" etc so that she asks herself those questions. Honestly the ones that seem most vulnerable are those ones where their parents are micromanaging - but that's probably just symptomatic of larger issues.
It's interesting to hear what people consider window breaking and window making. Even in the canonical example of lawyers (who only "split the pie"), some provide a social good by defending innocent people against what some people consider a corrupt body of laws.

I recently finished reading John Brunner's "Shockwave Rider" and found the taxation proposal near the end intriguing, if a bit alien. Tax rates are adjusted based on scoring of profession on three axes: training/talent, drawbacks (like unpredictable hours and dirty working conditions), and social indispensability. On all three axes, advertisers would score a zero, thereby qualifying for a 90% tax rate. I wonder where people would score people who work in a lot of these startups? I suppose it would depend heavily on what the startup was doing.
