> And are these benefits worth the massive amount of wealth extraction from the rest of us that HFTers are engaged in?

Unless you were a specialist market maker or pit trader on an exchange there hasn't been any "wealth extraction". Quite the opposite, HFT has taken a system built on being tall, having good connections, and understanding an arcane set of hand signals (not to mention very high fees) and replaced it with a ruthlessly efficient automated system based on being good at writing software and planning network setups (and brought the fees down with it).

For the vast majority of market participants HFT has been a massive upgrade over the old system and dramatically lowered the cost of trading.

A random mutation that suffers no evolutionary pressure is usually spread randomly across the population. Eye color for example.

As opposed of something that gives an advantage (like lactose tolerance or falciform anemia) which usually spreads quickly, while those that don't have that advantage died out.
You're totally right, you're a pedant. JK, I was indeed confused, I don't know how to call a long chain of parallel associations like flash,fla -> flash gordon,alf -> gordon shumway -> shumway. Maybe it's a first.

I'm not convinced. To get someone's passcode, I have to watch them type it in; something that happens in few places, at few times, and when they do it they will be aware of the need to not let me shouldersurf.

To get someone's fingerprints, I can simply wait until they touch something, or if I don't want to do it that way, I can take a picture of their fingers. I could do this from a distance without them ever knowing.

Sure, once I have their passcode, it's a lot easier that making the physical fake fingerprint, but getting a copy of their fingerprint is easy.
Can you quote me some stats on how much the equivalent middle men made in earlier decades? Both absolute and relative to the size of the market?
1. Currently No, but for 5 years, yes. Now only indie in my spare time.

2. I was primarily developing for consoles (PS3, X360 mostly), with some PC work. Now primarily PC and Mobile.

3. Over 70% C or C++. In industry (AAA Console) I was probably 90% C++.

Lots of people do use IDEs in the industry, but lots of people also don't. It's a choice.

Spoofing, which is what you are describing, is not useful for countering HFT, it is used to change the market price of an instrument by exaggerating the demand for it. This has obvious detrimental impact on any one, HFT or otherwise, who is trying to price the instrument.
A lot of the methods I listed don't have anything to do with speech per se. They DO have something to do with how to use data to e.g. remove unwanted variability or achieve better class separation. What makes them old methods is that they were developed in the context of using Gaussian mixture models for modelling Hidden Markov model state output probabilities. As such you could perhaps apply them in classifying birdsong, gunshots, or whatever else (with varying success, of course..).

I have no doubt that these methods and their acronyms will become irrelevant (perhaps they already are), but I guess some of the basic underlying ideas about variability will re-emerge in the training regime of DNNs. Sure, the algorithms (and implementations) for training DNNs are the same, but these ideas are incorporated in the preparation and handling of training data (compare that with augmentation, like creating translated images etc.).
I think the general conclusion isn't just "If something looks too good to be true, it should be treated with great caution" but "If it relates to food or drink, we know diddly squat". And even less if the purveyor of said knowledge is not even a full-time research scientist. Or heck, not a scientist at all. Sadly that seems to be the source of 90% of diet "wisdom".

Now let us get back to honestly saying that we like to drink to get sloshed, without any excuses of health or even just taste.

Slight tangent: I've spent the past week experimenting with different kinds of bitmap caching achievable in the browser. Given that you understand both the browser and the way DisplayObjects implement bitmap caching in Flash, I was wondering if you got any clues on how to optimize DOM heavy pages? There are quite a few situations where momentarilly swapping out complex static DOM with a bitmap representation would decrease drawing calls. What I don't know is, to what extent are browsers smart about caching the renders, and when the overhead of caching by canvas would be smaller than default DOM rendering. However, I've had plenty of success in increasing performance, for instance, using canvas to resample images from original to DOM element size, so I'm optimistic about bitmap caching as well.

I'm on a friends tablet now, but I'm looking forward to digging through the implementation later. Keep up the good work!

P.s.: Did you find parts of AS3 beautiful? :-)
Shellshock was a big deal because the attacker only needed to control the value of an environment variable, not its name. There are many vectors to provide a string that will end up stored in some environment variable, far fewer that will allow you to specify a particular name/value pair.
Well it's all definitely overkill. But on the plus side, you can sell these bulbs to people who can plug them in without needing to re-wire their house.
What is the power limit of POE? I don't see a reason to try to dim LEDs on AC or a reason to keep converting DC/AC/DC/AC so often. Wouldn't POE or a similar standard be better?
It's like stream of consciousness, I'd call it serial association rather than parallel. "Sui generis" maybe?

They both takes tons of government money (admittedly, for research, rather than teaching.)
If there were, there would be finitely many repunit primes (via the pumping lemma and the notion that there are arbitrary large non-prime repunits).

Edit: that's not quite correct. The above would imply some simple structure in repunit primes. If you add the known asymptotical behaviour of the 'number of primes < N)' function, I think it would imply it.

Also, in binary, it would either imply there are finitely many Mersenne primes, or that there is a N such that all Mersenne numbers larger than N are prime (edit: Mersenne numbers are repunits in binary)
A possible application would be to have different temperature regulation for occupied rooms (With some smart scheduling that anticipates occupancy).

So there's a reason to integrate the HVAC system with awareness sensors (which will probably be integrated with the sound system).

Not an interesting feature for an apartment or smaller house, but it's a reason to try to build the systems so that they can talk to each other.
If you have to set options or even program to get it started, it's definitely not so smart.

We see crazy competition on latency because these firms can no longer compete on price. HFT has taken the spreads down from $.25 to $.01 (putting a lot of market-makers out of business, saving a lot of money for anyone who is actually trying to buy or sell shares). But since the price isn't allowed to go below $.01 (sub-penny rule) the firms are now all in this wasteful zero-sum race to get that $.01.
Do share how you get on. I'm in the same position as you.
Am I the only one who thinks this article contradicts itself? Starts off leading towards some great conclusion that any amount of alcohol is bad for you, then tails off with this:

"The team found there's at best a small decline in mortality rates for men aged 50 to 64 and women aged 65 and older. Former drinkers, meanwhile, had somewhat higher mortality rates than others, suggesting that past claims light drinking was good for your heart were based on faulty comparisons. After all, some of those who'd quit were probably heavy drinkers in the past, and, compared to them, light drinkers had likely done less damage to their hearts."

In summary, it appears to be saying that there's a small benefit in light to moderate alcohol consumption but heavy drinking is probably bad ... uh no shit, that's what people have been saying for years?
It was probably a sequence of thoughts, but the flash gordon | alf relationship is parallel, they're unrelated above the convergence point that is shumway.
Thanks to maxerickson for expanding on the article that I obviously didn't read.

I would strongly agree with mathgeek here though - it's best to put the relevant details in the title to enable me to see if I should even read the article or the comments, and to edge on the side of safety that not everyone here is in the same country, age bracket or work/social circles as you. I've never read the NY Times. I'm not in America.

I mean Steve Strange died today too - if I just posted a headline stating "Steve Strange has died" I would get a barrage of comments asking - "who is he? why is this relevant to me?".

> compared to a randomly sampled population consuming the nutritional equivalent in natural products.

Define "nutritional equivalent" and "natural products"?

Do you just want the same levels of carbs/fat/protein as Soylent has, or do you want to also get the same levels of iron, sodium, vitamins, etc.? The more demanding you make that condition, the closer you get to just replicating Soylent. ("We could replace this artificial ingredient with that natural one, but the natural one has less salt, so to make up for that we have to...")

And it hardly seems fair to compare Soylent against a natural equivalent of Soylent, which doesn't currently exist to my knowledge, instead of against people's actual real-life diets.
You are, perhaps, somewhat overusing various graphical effects on that page. Consider toning it down.

I wasn't arguing against informative headlines.

I was labeling those comments as pointless. They frustrate me a little bit (because of what I said above about reconciling the supposed interest behind the question with the paucity of (misdirected!) effort).

[DRAFT] Web Real-Time Communications Working Group Charter
Could you explain in what sense classical statistics is actually a worst-case view? i.e., can you link to a page or maybe explain yourself explicitly (i.e., using a min() operation) how classical statistics is a worst-case analysis? What scenarios is it actually worst-case with respect to?

It's always seemed to me that the differences I see, such as in ML vs. MAP, are not due to a question of worst-case versus average-case analyses, but rather no-prior-knowledge versus yes-prior-knowledge analyses. I've never seen a proof that classical statistics gives a worst-case bound.

Doesn't that parenthetical comment destroy the rest of the [small sub-]argument: because you paid someone for doing research doesn't mean that if they decide to make something else free to access that you have a right to make further demands of them.

If central government just gave them a stipend and didn't specify the projects it was to be used on then the argument you're supporting would perhaps have some mileage; but it's payment for a specific service. If the schools aren't making their research centres accessible or are unnecessarily excluding disabled people [from research related tasks/benefits/etc.] then, yes, this argument would be valid.
I feel like there's some kind of rush to become the box/service that runs your smart home. None of these vertically integrated solutions is going to cover all of the use-cases or user desires, yet it seems that everyone want to be the one that sells you their proprietary (and bug-ridden) box.

It would be much easier if most of this stuff could be shipped as software that you can install (somehow) into a box of your choosing and pull together components for your home as you see fit. This field isn't ready for consumers per se but those with a more hacky mindset would probably uncover the useful bits, which could later be picked up as integrated solutions.

Standard PSA about "Flash Boys". If you are interested in HFT you are better off quite literally not reading that book than reading it. It is very biased and largely inaccurate.

Thank you very much. The english version of wikipedia state that Roger Garaudy and Jean Plantin has been jailed whereas the french version of their wikipedia pages state they hasn't been. So it would be good to have reliable sources.

BUT you actually pointed me to a guy that has been an exception to both of my statements. Vincent Reynouard has been jailed for revisionism after having published a book and a video tape about the massacre of small village in south of France during War World 2 https://en.wikipedia.org/wiki/Oradour-sur-Glane

And even before that he lost his job as a teacher because he had some revisionist document on its work computer http://www.liberation.fr/france/1997/04/23/le-prof-revisionn...

So he is really the exception which proves the rule.
This. I have to say my happiest and most productive period was when I didn't have a desk job. I found a trick that worked really well was to start the day with a list of accomplishments that I thought would take less than 6-8hours. Often framing it like "I'll be happy if I do X,Y, and Z". If I finished in 15 minutes, I was done for the day. If I didn't finish by my 6-8 hour time limit, then I was still done for the day, and tomorrow I'd try to break up the task in such a way as I could finish parts of it in less than a day. I think an important part, and something OP might note, is that framing the tasks in terms of "happy if" really changes the psychology of the process. No longer can you say "I did all this stuff and it's not enough", since you already identified enough at the beginning. This coupled with the constant readjusting of expectations really helps avoid feelings of anxiety. I'm not sure this helps for a failing business (or if rent is due tomorrow) but it certainly helps if you have even a month's runway.
I imagine that it would be even easier to look at European companies, as there has been lots of border changes there.

According to a quick search into Finnish companies, the currently oldest one (Fiskars, founded in 1649) has survived the transitions from Swedish rule to Russian rule (1809) and to independence (1917). The owners have changed several times. The oldest one that remained in the same family seems to be Frenckells printshop, which survived from 1642 to 2008.

Hello, I'm a software engineer and I’ve never had a decent keyboard. My last one’s just died, and this $8 stand-in is awful.

This time, I want to get something for my PC that makes my 8-10 hour/day programming/writing easier on my fingers and wrists.

I have small hands (full-stretch span from 1st to 4th finger: 12cm/5” - on a MBP, hitting Return with my forefinger on ‘J’ is not comfortable)

I’ve also been straining my shoulder, so need tenkeyless or smaller, such that my mouse isn’t so far out.
