I don't know why you need a great clock either, if you have stable, symmetric network paths from a central location to all your servers colocated at exchanges, you can predict the delay between sending from the server and getting to the exchange, you can split your order and send it to the various exchanges with appropriate delays and know that everything will arrive at the same time. If you're wrong, it's going to still be close enough that nobody will be able to see it on one exchange and react to it on another before your order gets there.

This was the first thing I thought of when hearing the flash boys story on the radio: The banker was complaining he couldn't capture the whole book across exchanges because resting orders were cancelled before his order got there -- he just needs to get his orders to arrive close enough in time (although expect a bigger tick, probably)

HFT firms will try to detect when equities traders are doing this. e.g. If they see a pattern indicating that chunks of shares are being bought, they will try to buy, too.

Price discrimination against large traders - grandma gets a better price than Bill Ackman - is a valid and real HFT strategy. They do it in the manner you describe.

But it's not front running. It's only front running when your agent (usually your broker) does it based on private information.

Front running is just a term Michael Lewis misused in his misleading advertisement for IEX.
Now that tech hiring has slowed, it may be true that its moment has passed. But that doesn’t excuse many of the misleading points in this review.

“Hack Reactor was created in late 2012 by DevBootcamp grads.”
This makes them sound like recent bootcamp grads. Shawn Drost studied CS at USC and was a technical team lead at OKCupid. Marcus Philips was an engineer at Twitter.

It describes (unfairly) the skeleton of the average day as if that’s all there is. There are frequently other lectures and guest speakers, and daily presentations and other discussions. There are also resources, assignments, and support before you even start the program, and support after.

“The students assigned to help during the sprints have graduated just before you started… Unfortunately they are not experts.”
Their role is not to “give” anybody answers, but to get you unstuck. If you’re truly hopelessly stuck on something, then there are experts who step in.

“The third month you’ll work on your thesis project with a team chosen for you.” You have a lot of input over who you work with, and they accommodate switches when possible.

“The second half is cruise control.” That’s like saying a thesis semester is cruise control. You meet daily with an expert who functions as a PM. It was very comparable to real world programming.

The criticisms of the condensed nature of the program miss the point. They’re designed to make you autonomous and accustomed to agile practices, and not be someone who becomes easily lost with unfamiliar problems.

“Another observation, most people who get in, are already qualified people, with top university degrees.”
This was certainly not true of the cohorts I saw or the people I interviewed when I did admissions for them. Roughly half had CS backgrounds, and the rest were changing careers.

A few candidates I interviewed attended previous bootcamps, and I saw no improvement over regular candidates. Most did not get in. With one exception, the alumni I know of (graduating 3-9 months ago) ended up in good jobs in line with their outcomes statistics. I don’t know if Hack Reactor is still worth it in today’s market, but painting the program as some kind of scam or bait-and-switch is not the sentiment of anyone I know, and this article makes a lot of dishonest points to get there.
Nintendo Surges as Pokemon Go Downloads Top App Store Rankings
If I'm a recent graduate (non CS major) and I have been learning JavaScript since last September.. should I join a bootcamp to become a frontend developer or is there a better path? I taught myself everything and now I use AngularJS and NodeJS. Half way trough a web app and will deploy it on Heroku to get some feedback. But I don't think I'm job ready yet since I don't know the best practices or how to write cleaner code. I thought about bootcamps, but people have very different views on them. I graduated from a top 10 business schools with latin honor. Took a few programming classes and really liked them. So I want to become a frontend developer even though I don't have a CS degree.

What should be my next steps? Or which bootcamp should I go for?
That's a large part of the problem.

23andMe will not provide any person's data (genetic or non-genetic) to an insurance company or employer.

We have been long-time supporters of legislative efforts intended to prevent genetic discrimination and to safeguard individuals' genetic privacy. In the US specifically, we were active in the development of the Genetic Information Nondiscrimination Act (GINA) enacted in 2008. GINA is federal legislation that protects Americans from discrimination in health insurance and employment decisions on the basis of genetic information. GINA does not cover life or disability insurance providers.

In addition, we have supported the California Genetic Information Nondiscrimination Act (Senate Bill No. 559), which was enacted in 2011.

The top 50% get a UBI, but most plans would pay for it by increasing taxes on the wealthy. There would be a cutoff, so that above a certain point you'd be paying more in extra taxes than you'd receive in UBI.

The vast majority of UBI plans definitely aren't regressive.

Thanks everyone for sharing the stories. I have been working on a startup for several months, pivoted and I'll release the new concept in the next weeks.

I think the biggest hurdle of doing something alone is keeping yourself emotionally stable. If there are more people, when you are down the others can balance it out.

Has anyone experienced this?
I've never done any project in Unity, AR, or VR. I was thinking I should try it out. I've never thought of thinking about it the way you suggested, which is using the gyroscope.

This is another one of those articles where some person explains why their interpretation of some aphorism failed to work for them. The problem, of course, is that they are interpreting the advice differently than intended and they are generalizing their personal experience and understanding of their own motivations. People are not all the same. Some of this advice I agree with, but some of the strategies that the author claims have given him success have failed for me.

For example:

the problem is not your productivity, it’s instead that your mind is not yet sold that you know how to succeed with your general goal of becoming a writer.

Convincing my mind that I know how to succeed is not a problem I have. I'm very arrogant and I believe there is nothing I cannot do if I set my mind to it and have adequate time. My problem is that my mind prefers short term satisfaction via diversion rather than the long term reward of hard work. So for me his advice if absolutely backwards. If allow myself to be flexible with when I write/work then I'll never get anything done, because, hey, I can always cram later and get it done. For me, setting up a habit, "Write/do X every day," is good advice. I just need to force myself through the first 10 minutes and then from there I'll get lots done.

Btw, the kernel of truth he is missing from the "write everyday" advice is like others have mentioned: regular practice makes you better. The goal isn't to make forward progress on your one big project everyday, it is to get some form of practice in every day. Write something every day.

> Buy same security faster than rest of buy order can be processed.

How? You can't because your competition is already resting orders there (from potentially weeks ago) and any order you put in there will be behind your competitors no matter how fast you are.

What does happen is that you all are resting orders up and down the order book. When a big order takes out several levels of your orders, you race as fast as possible to cancel those same levels at other exchanges. If you are faster than the big order you only get hit for a single exchange.

Its a risk mitigation technique, to keep your profits from your regular business of making the spread, not risk free profit.

So one place firms are racing is on the cancel side. The other is on filling back in orders after the big order has cleared levels. The faster you are there the better priority your resting orders will have (potentially weeks from now).
A multi-armed bandit will occasionally provide 'random' items as part of the exploration phase. Perhaps that's what's going on, and not any sort of diabolical self-fulfilling prophecy.
The top 50% get a UBI, but most plans would pay for it by increasing taxes on the wealthy. There would be a cutoff, so that above a certain point you'd be paying more in extra taxes than you'd receive in UBI.

I can't remember seeing a single UBI plan that is regressive. The goal of almost all of them is increased income equality.

There's not really a difference in this and increasing the EITC except in perception--eliminating means testing so that everyone gets the UBI, which many people think is important.

Austin and Atlanta themselves definitely don't lean Republican. NC cities are reportedly getting much more Democrat-leaning as well, though I haven't kept in touch with the people I know Raleigh/Charlotte for a while.

Also the legality of abortion (Roe v Wade, 1973) could be a contributing reason. The drop in crime came about 18 - 20 years after abortion was declared a constitutional right. Most crime is caused by teenagers and young adults.

Not really sure why this is news now. According to Wikipedia, Moore has been spouting off on global warming (among other things) for quite some time now, and not without plenty of controversy and criticism.

You haven't even described a strategy. Guess what, I made a bunch of money off brexit by buying low and selling high!

Consider the alternative way this "strategy" can go:

- Put in a standing order to sell a small amount slightly below market.

- Wait until you receive a "TRADE CONFIRMATION 100@$10" message.

- Buy a lot of same security very fast and put in a sell order at higher price.

- No one actually buys it.

- Loss

This is actually a very risky strategy and very few people do it.

What's actually happening most of the time is a far less risky one:

- Put in standing order SELL 100@$10, 100@$10.05, 100@$10.10

- When you receive TRADE CONFIRMAtiON @ $10, cancel other orders and reprice higher (maybe $10.20 and $10.30).

- Maybe put prices back if you don't get filled in an hour.

The goal here is to offer a good price $10.00 to Joe Sixpack (no delta toxicity), but to offer a worse price to Bill Ackman (high delta toxicity).

Front running is a serious crime, with clear definitions.

What you are describing isn't front running (or even illegal).
This argument is also used against increases in the minimum wage. Now almost everything in economics is up for debate, but very few economists agree that raising the minimum wage by X dollars will result in prices rising by X dollars so that the effect is non-existent.

There are several reasons for this, the biggest is that cost of labor isn't the only input in pricing.

Basically the cost of supply constrained goods will go up, but not enough to outweigh the increased purchasing power for lower income earners.
Do you destroy this information once the owner has chosen to opt out?

The reason I, and I suspect many others, avoid these types of services is the risk of this information being inherited or possessed by an entity that would use this information in ways to which I do would not consent nor approve. This information would not only affect me personally, but also my children.

Germans are more privacy-aware than most for a good reason. I dread a future where an evil government gets a hold of this data and the technology to effectively use it.

A lot of people would honestly prefer to wait in a line (seems fair on the face of it, everyone treated the same, first-come-first-serve) then wait a less-transparent amount of time due to people willing to pay more to (effectively) jump them in line.

How do you think people would react to grocery stores saying "oh, the checkout lines are long right now, everyone gets hit with an extra 20%!" The underlying mechanics are different, but that's kinda the customer experience it gives off.
There's nothing lift-serviced in the US above 13k feet. Colorado has a number of 14ers, but no lifts run that high; the highest is Breck, where the highest lift runs to just below 13k. That's high enough to make everything more tiring, but low enough that there's no serious effects for most people. Even in CO, most ski lifts top out between 11k and 12k.
The idea doesn't help the hft'ers. It takes an order, secretly transmits it to computers each as near to the major markets as possible, with instructions so that the computers submit the trade offer at precisely the same time.

The hft'ers can't make money since they can't outrun trade offers that are synchronous across all markets.

I hear this argument a lot in young liberal circles, can't wrap my head around it. In particular given how much well deserved flak the tobacco industry has gotten, industry also driven by addiction. Drugs are addictive, messing up people's rewards path and inducing self-destructive and asocial behavior. Priorities are:

1. Keep as many innocent people as possible away from drugs.

2. Help as many junkies recover as possible.

3. Fuck the dealers.

Legalizing drugs seems to reduce the risk for dealers, now having their posh addiction-driven business at the mall, while increasing the availability of drugs for the untainted population and for the junkies. Are we really that concerned by dealer's quality of life that we willing to tradeoff the lives of our neighbors, friends or even family?
I think the assertion is that these particular people have a privileged position primarily because of their high quality contributions to the community, and the argument is that this is fairly appropriate.
I'll give them the benefit of the doubt on this. The "free shit" is a sales tactic but also a genuine belief that the best way to ensure prosperity for all is through a planned society.

Funny enough, the moment I stopped caring so much about time and optimizing it, the more productive I got.

I recommend reading Jacob Needleman's book about Time and the Soul.
