Natural large volume traders prefer an exchange that doesn't price match this way. No one is preventing them from creating a dark pool (which is what IEX is) and they already have any number of dark pools available for this sort of trading.

Turns out many natural traders (Vanguard is the one that comes first to mind). Really like trading in the new HFT world as it is way cheaper than it used to be.
I could be mistaken, but I mapped the route and it looked like his job entails biking 1.6 miles. Big whoop.
Yes, some big portfolio guy wants to be able to sell 50M worth of some stock without the price dropping.

But what if you were buying stock at the same time? Wouldn't you want that information about that rise in supply to be detected and priced into the market as fast as possible?
I'm pretty sure that the Wave project already spent all its credibility. When something is hyped that hard and fails that spectacularly, it doesn't tend to get a second chance.
Yep, and those with mindless mechanical jobs often wish they could sit on their bums and think all day. A good balance is probably the right approach!
You can pay for a lot of things and that doesn't mean it's not in the interest of society or the market as a whole either. The trading in any one instrument on an exchange is a zero-sum game, but the structure of the market and the relationship between exchanges, buy-side firms, sell-side firms, and retail investors doesn't have to be.

Before electronic trading, the specialists who executed orders on the NYSE floor ALSO paid shitloads of money for their access.

One difference between today and the heyday of the specialist system is that in the specialist system, middlemen skimmed overtly from investors: the bid-ask spread was gigantic, and all that money went to the middlemen.
PFfPL is a great book. It manages to present many seemingly different language features in a surprisingly unified way.

It's very opinionated at times (usually against anything "dynamic", eg. typing and binding ;) ) but I think it's worth it for the clarity that it allows. Of course, Bob Harper has the clout to back up those opinions!
I would disagree that any of those things you think are hurting you are that important. They're certainly all nice-to-haves, but if I were looking at your resume I wouldn't think for a second of discounting it just because you didn't have those on there.
Proof? Or is all you have his donation in favor of Prop 8? because if that's it, you can't claim a trend with one data point...
LOVE this idea. A great way to get exercise and force yourself to step outside our little startup/tech bubble to experience more of the "real world".

I've been considering doing something similar, so this is quite inspiring. Thanks for writing this!
ETF Arb and Latency Arb ensure that the ETF always correctly valued and valued the same across all exchanges.
I felt the same way until I was diagnosed with sleep apnea, even though I don't have any of the usual symptoms such as snoring, obesity, etc.
I agree. It's a big pain point for me. I've been using ConEmu recently which supports resizing and has tabs (among many other features). My favorite other feature is the tasks: you can define a set of steps to run as a task, then launch that task in a new tab.

See comments above, the original research is flawed. New research shows that moderate caloric restriction has no statistically significant effect over eating a healthy diet within your caloric needs. It is overeating which decreases your life span.
There has been some work on integrating Wave with email (initially as a way of using Wave as some mailing-list replacement tool). See WAVE-70 (https://issues.apache.org/jira/browse/WAVE-70).

Chat integration is arguably simpler - and Wave already understands XMPP (for federation), so it would be possibly to map Jabber -> Wave (say). How you would want to map from Wave -> Jabber is more complicated (as any blip at any point in the tree, can be edited at any time, by anybody)...
What's wrong with arbitraging trading activity?

If MSFT is trading for $50.00 on one exchange and $51.00 on another we want someone to fix that price discrepancy! Even if the difference is much smaller we want that balance to be corrected!
I will refer you to page 96 of the book. The specific example is 100 shares of MSFT asking $30.00 and 10,000 shares asking $30.01. Because of Reg NMS, your broker is required to take down the 100 shares first ("NBBO"), allowing the HFTs to then start buying the $30.01 offer and front run the remainder of your bid. The problem with this requirement, according to Lewis, is the NBBO is priced off SIP rather than direct feeds. I don't disagree with the literal point that you are making, however, there is no need for this kind of intermediation. Why should natural traders pay intermediaries for this function? Why shouldn't they coordinate on an exchange where they don't face this tax?
so you spend ten minutes a day riding your bike, and you found a way to get paid to do it? anything else?
Stop drinking coffee. About 7 years ago I cut out all caffeine and I've found myself being less tired and more alert in the morning. Granted there are days where I don't want to drag myself out of bed mainly when I know I need sleep, but I no longer feel like a zombie until coffee in the mornings.
I can see an argument for intentionally leaving that info off. They are a local site and don't really care about one off traffic like mine or yours, we won't be coming back anyway. And specifying that info may make the site feel less local to the actual repeat audience.
As I read the article I kept expecting the part where he was suspended from school for the rest of the semester for breaking the school's zero tolerance policy on "cyber attacks" or something.
My 2 cents: No don't do it.

Six months is a very short period in time, you'll be surprised how quickly it flies by without you haven't accomplished much, at which stage you'll be out of a job and money and little to show for it.

Is there a reason you can't do these projects on weekends and in your spare time?

Even if you manage to finish some projects, what makes you think these would automatically make you a very attractive engineering candidate?
It's not April fools anymore... right?

Some old technologies just do not deserve to be romanticized. LPs, maybe. Brick phones, no.
I was under the impression that the bulk of the cost of a drug was not the research, but the clinical trials and the FDA approval process. If so, it's only fair to charge more in countries where it costs more to get the drug approved.
I think it's fair to say he would not have stepped down had this boycott not happened. Furthermore, the Board could have refused his resignation, saying, if you're stepping down because you believe you're a liability to the company, don't. Stay on and we'll work this out.

Perhaps that's actually what happened, and Eich chose to step down anyway. We'll probably never know. What we do know is that current trend of politicizing everything has reached a new milestone (and a new low).
I don't see why you would need a github profile, etc., for those things, and if you think that improving your public image as a developer will land you a job with such a company, you may be right, but I think you are looking at the problem the wrong way. Many jobs offer the last two things in your dream job. A few jobs offer one of the first two, often at the expense of the latter. A very few jobs offer all four. How do you expect to tell that a company has all of these attributes? Unless they are a very high-profile company, you have very few data points to go on. Just like you talk yourself up during an interview, the company will talk themselves up, and often misrepresent and overstate what they have to offer.

Case in point, I'm actually in a somewhat similar situation, and am aggressively looking for an out. After returning to school to finish a degree I was hoping to take a different tack in my career. I really wanted to work on scientific applications with something more in mind than just the bottom line. I accepted a position that offered mostly remote work. They already have an established remote workforce, and it appeared to be a true meritocracy, with little management overhead or fixed structure, and lots of very bright talented people working on interesting projects. I had several interviews, including a day long in-person interview. I turned down three other very solid offers to take this job.

Fast forward a few months and the picture they painted could not be further from reality. The people in the office don't have phones, so talking to them directly always involves jumping through hoops and can take a long time to set up. People are often unwilling to talk at all and prefer to hold terse conversations over IM. Lack of management structure translates to lack of communication and support from above. Some things about the job were grossly misrepresented and there was one major outright lie that would have been a deal-breaker from the start if I'd known about it.

But the job looked perfect! I looked like a great fit to them! This is a career, don't count on a quick fix or finding nirvana in a day, or six months. A friend of mine used to say, life is the process of finding the things that don't work. If you put yourself 100% on the line hoping for a big payoff, you are more than likely not going to be happy with the result. Just look at how many startup founders on here have failed over and over before making it, and many never do. I see no reason to over-extend yourself like that for the sake of a salaried position, at least not without some really clear goal at the outset.
Interesting "hack."

If this works for you, and makes you more effective for your company, awesome!

Have you given any thought to the long term effects of sleep will be for you?
Really interesting to see the iterations from obviously awful through acceptable all the way to obvious in retrospect but takes a non-obvious amount of thought and design.
My employer (IBM) allows people to do things in their spare time with the following kinds of exceptions (off the top of my head, sure there are more):-

a) Do not use company time or equipment. Pretty obvious that one.

b) No doing something that competes directly with IBM. This has to be more specific than "working with computers". It means I can still get beer money for helping friends/family fix their computers/servers, but I can't start a small consultancy that aims to take possible business away from IBM. I can start a social sports related side project website because IBM aren't in that space. But if I worked on Websphere Application Server (I don't!) I couldn't contribute to, for example, Apache Tomcat/Geronimo or JBoss AS. I could write my own game Apps and sell them through the App Store. Etc.

c) Contributing to OSS in your spare time needs to be cleared with IBM, just in case. The main reason is that everyone loves to sue IBM and OSS is fertile ground given the various OSS licenses and implications. If I do some work on some OSS package in my spare time it means I'm tainted in that area. If I then do any work on a commercial application in the same area then it opens the door for people to claim that the commercial work I've done has some work that could have been influenced by the OSS code and part of the commercial application is therefore derivative of the OSS work. With some OSS licenses this could mean that the entire commercial application is considered a derivative work and, depending on the license, the source code would need to be released or IBM could not charge for the software, etc.

It's not all doom and gloom. I work with some people that have got clearance to work on OSS software, they just have to make sure they avoid working with anything related to it on the commercial side (to the point of not having access to the source code to provide plausible deniability). You also need to think in advance and not work on anything that we could reasonably be working on in the future.

We are also regularly warned to avoid even looking at any OSS related to the commercial code we work on, for fear of tainting. Same for Googling for answers to technical questions and copy-and-pasting code from SO or elsewhere. You've generally got no idea of the copyright/licensing aspects of any code you see in the results.

IBM does use OSS in some of its commercial applications. Its use is always cleared with the lawyers first though. Certain licenses must be avoided simply because they are incompatible with selling commercial software. Where the license is permissive we always make sure we follow the rules and I've personally contributed many bug fixes in the OSS code back to the community as required (or even if not required!); these have often been found as the result of formal code inspections (which IBM is effectively funding by paying employees to perform it), peer review, static analysis tools, or general SQA testing.
This. I thought exactly the same.

Being woken up at 7am and getting that daily dose of smiles is exactly the same if not better!
This article seems like nothing more than an overly long ad hominem attack.

The only critique that matters is whether or not front running of buy orders by HFT traders is real or bull. Anything more is just an attempt to cloud the waters.

I'm really not, I am missing your point.

The majority of 3rd party Go code simply uses the Go stdlib just like our hypothetical program.

Go is no less platform independent then Java, for example, yes there are some 3rd party Java libraries that use JNI, just like some Go libraries use cgo.

The fact that these native bindings to (often) platform dependent code exist does not make pure Go/Java programs non-platform independent.

Maybe our misunderstanding is what we mean my 3rdp party libraries, I'm thinking of the Go repos people put on github or the Gorilla project (http://www.gorillatoolkit.org/), I am not talking about using cgo to call glibc or something similar.

The major issue with PyPy is that it has a radically different C API than CPython, leading to incompatibility with NumPy, Pandas, etc. to mention just a few prominent performance-critical Python packages that are written in C. PyPy works if you want to use pure Python code, but that's rarely the case in real-world high-performance Python projects.
I've reread Liar's Poker at least 5 times (it's what I read when I don't want to think about what I'm reading next, because you can pick it up, turn to a random page, read in either direction, and enjoy yourself for a few minutes).

Read reviews of the book from traders and you will see lots of people scratching their heads the same way I am.

It is confusing that a former bond salesman, who wrote several famous vignettes about how Salomon got its clients into jams by selling them blocks of bonds and having the market move out from under them, would believe the things he appears to believe about RBC's role in the market.

In Lewis' universe, a $2MM/yr sell-side broker accepts a 100,000 share block order from a hedge fund, consults a single blotter screen, enters a 100,000 share order, and is startled and outraged when that order isn't as easy to place as an Amazon one-click order. Egads! The broker has to actually work for his money! Kill the HFTs!

I don't understand what inventory hedging has to do with the point I'm making. Hedge trades are trades. Large hedge trades involve block shopping.
The other comments in this thread explain it much better than I could, but I will also throw in my 2 cents and add that you should absolutely not cash out your 401K. You're better off finding a better job. Once you do, you won't have to think about dipping into retirement savings for this.
If I was, say, playing football with friends, and somehow got mud on my inner thigh, I might wipe it off with paper, and then later take a shower.

Seems like we are in very different mindsets when discussing the whole thing.

First of all, I do not share the idea that growth is the only to measure success. In fact I strongly disagree with it. Colin's idea of success could as well be "What is the state of art when it comes to secure backup software? When Tarsnap is the answer, that will be considered a success".

Second, you seem to be too hung up on the idea of keeping the business alive. I was semi-serious when I was talking about the post-scarcity world. In my ideal world, Colin would be out of work, just like me and everyone else. I want secure-backups to be a commodity infinitely cheap, not something that I may get for free only if someone else is subsidizing some artificially larger cost. I want Colin to work on things he cares about, out of his own personal interest, not for this SV fucked up measure of success.

Third, I know my blog post is boring. That would be the whole point, actually. Don't forget we are talking about fucking BACKUPS here. They are not supposed to be exciting or deserve all this ink we are spilling over it. The point what I am trying to make is that, what I would see as an actual contribution worth of praise (and even value) would be if Patrick went through the boring parts and muck and said "Hey Colin, I know this is now what you want to focus on, but it's important as an user of the product, so here you go."

Was that we got? No. What we got was some blog post from someone "highly trusted in the community", which works only to establish that he "knows what he is talking about". And yes, there are people willing to pay large amounts of cash for this. I wouldn't, and it disappoints me that so many people here do.

Lastly, this is not an attack on Patrick, but rather on this mentality that is so widespread and so exposed on the blog post.

Unfortunately (and especially because of the evidence of the cycle that begins with "the doctor increased has dose" and "added another medication"), Wil has a pretty good chance of having a poor outcome. Especially because his medical advice seems to include the deeply problematic "chemical imbalance' theory.

Reading Whitaker's "The Anatomy of an Epidemic" (https://en.wikipedia.org/wiki/Anatomy_of_an_Epidemic) should be required for anyone considering long-term use of neuroleptics, benzodiazepines, or anti-depressants. And for those who care for them.

I agree that CLIs are ofter better than GUIs, but I think the point was that the Linux CLI tools could have been designed better. For example, personally I don't like how gzip/gunzip comes in a pair, but there's no "untar" command, instead you must pass the -x argument to tar.
You are working as a full-time software engineer and you think 6 months of answering StackOverflow questions and working on your GitHub profile are going to be better for your resume than continuing in your job?

Get a new job. If not your dream job (yet), some job that is incrementally better. Apply for jobs. Interview for jobs. That will teach you a lot more than hanging out on SO.
OP simply doesn't say that. OP refers to the actual common act of washing hands after using the toilet, not the hypothetical act of washing hands after getting "mud" on them.
Why do you find it strange? When I load tencent.com I get a blank page (I keep javascript disabled by default) and then when I finally get the page loaded, it loads in Chinese since it didn't detect my language either by HTTP header or by IP. The page looks like the typical boring corporate home page (I can't even tell it's a social network). I then switch to English and I see that tencent.com is not the homepage for the social network, but the parent corporation that owns the social network its responsible for. I can tell this from typical corporate specific stuff like talking about stuff like quarterly earnings and stock performance, their vision ("to be the most respected internet company" ha!) and mission ("to enhance people's quality of life through Internet services". lol). Obviously, there must be some other home page I need to go to in order to join, but I can't tell what it is from the tencent homepage and the tencent name is the only one I'm familiar with as a foreigner so I don't even know what other domain I might put in the address bar or what query I might execute in Google.

With product management like this, they are never going to penetrate beyond China. Thinking they can compete with Facebook here is laughable.
I think it's acceptable to file clinical trials and the FDA approval process under research.
Spelling out where you'd like to take the project will help attract developers. Without some sort of direction the project looks aimless.
Currently working on a startup with a remote co-founder.
We meet maybe 7-10 days in a year.

Steps to increase odds of success:

a) Honest/open conversation & agreement on expectations upfront. No topic can be taboo from the first moment onwards. If you can't even get this far just forget it.
This applies whether the person is your lifelong friend or not. A business relationship if not a friendship.

b) Written agreement on those expectations - including everything from vesting upto what can lead to either one of you getting fired

c) Clear definition of roles/responsibilities, including who has the final say on specific tasks

d) Someone needs to be CEO and have 51% of the company so that when it comes to difficult decisions/disagreements on major strategic decisions, the CEO has the final say and that's that.

e) Have weekly calls (audio/video doesnt matter) to check in and catch up. More calls as needed.

f) Manage tasks/responsibilities using a tool like Trello so that at all times there is complete transparency on who is doing what and by when.

Bottom line communication & transparency is key - and you cannot have enough of both.

Hope that helps
