Second month of my standing experiment and I love it. Right now it's a temporary setup so I have my keyboard and mouse on a desk pad on top of a plastic file drawer for height. A gel standing mat for comfort. But when I get the chance I'll upgrade to a more permanent solution.

Here's my dream setup:

A Real-World Case Study on HTML5
There is a considerable amount of intelligence that continues to be gathered in the private sector about exploit authors, chinese hacking groups, and the actors involved in ongoing intrusions. Many of these groups conduct a fair amount of discussion and training pretty out in the open, confident of their status as out of the reach of western justice. Specific techniques and code present in a pair of Adobe 0-days used this spring point very loudly back to one collective and probably one or two specific actors that talk about these techniques in public in person. There are strong rumors that the night dragon intrusions track back to a specific actor. I've seen private investigator reports tailing specific intruders who verify that monitored intrusions happen reliably just minutes after people they have full dossiers on show up at their office. With many intrusions it's clear that the long term hosts are complicit in the bahvior. The wall of proxies defense tends to or at least can fall down against determined back hacking of the client.

All of these circumstances may not be the norm, but they exist. More would exist if there were more incentives to develop this kind of intelligence. The basic problem now is OK - what do you do with that info? NSA offensive security practices are not built for or available to the private sector. However, it seems very possible that these individual actors could be dissuaded, harassed, redirected or worse given the right program.

I'm not speaking of a state vs. state MAD. Perhaps I used the wrong term. But, even though I'm not a gun fan, there must be something to the idea that your neighbors may be less likely to break into your house if everyone knows you own a gun and you live somewhere you can shoot an intruder.
Or hold shift to keep the width/height ratio the same.
I've been experimenting with lots of different things. By far the most useful thing I've found is to take a running break for three to ten miles in the middle of the workday to break it in half. I have a standing desk and a sitting desk, and I've made a habit of standing or walking around when I have something to spend a long time reading. I tried sitting on an exercise ball at my desk and found it too distracting, but I found having a small exercise ball under the desk to kick around while working still lets me focus. And I've paid more attention to when I start losing focus while sitting and then to hop up and spend at least a few minutes walking around.

Presumably, the kind of person who would start their own HFT company is earning more than 85K/year out of college. Close to double that if they're a trader at a bank, potentially more if they're at a smaller firm and do well.

Still, 200K after two years of work is a tall order after taxes and living expenses. But given four or five years, it's not that surprising.
> In this economy, how many college graduates walk out of school into an $85,000/year job and no living expenses...

Probably the same people actually able to set up a HFT shop. Let's face it, this isn't for everyone. I don't think we should be crucifying the author on this particular point, it seems like there is a lot of interesting information to be had here.
So the purpose of currency is to serve as a proxy for goods and services. The basic question of monetary regulation is: "how much currency do we need?"

The Fed system actually somewhat regulate the currency supply based on the market. When you take a loan to start a business, new currency is created at the same time that a new productive enterprise is created. Gold and Bitcoin don't come from the market at all. The amount of Bitcoin added to the economy has nothing to do with the underlying economy --- its based on an arbitrary formula.
V8 convinced me it's not quite impossible to optimize such a highly dynamic language. JRuby on JVM 1.7 could be decent once everyone has a lot of experience with invokedynamic. But most have found MRI is nearly as slow as Zend (PHP), and we picked up 6x performance by migrating our critical stuff from there to Java (we have enough machines to easily make that worthwhile).

I've already found Ruby nice for stuff we're confident we don't have a reason to scale, though.
At my six-month point I have benefits and drawbacks from the experience.

On the good side, my back and legs feel much better than when I sat all day. I have lost some weight, though not enough to use that as a reason for standing. I am more likely to use my whiteboard for jotting down and sketching ideas. I find that I can think about plans and ideas more easily.

On the bad side, my feet hurt. Not when I'm standing, but when I wake up or get up from resting. This pain started about 3 - 4 months into the experiment. I wear thin-soled shoes which probably exacerbates the problem. Reading is more difficult, unless I have hardcopy.

Surprisingly, it didn't seem to affect my coding, neither positively nor negatively. I thought it would help by increasing focus. It also seems to make visitors a bit uncomfortable, unless I sit down to talk to them.

Going forward, I will try losing a bit more weight and using an anti-fatigue mat to stand on. Also, I will switch more often between standing and sitting, depending on the task at hand.
Logitech UltraX is still my weapon of choice. IMHO it's a shame Logitecht discontinued it.
Best laptop keyboard I've used is the one on my old 12" Powerbook G4. I can just fly typing on that.

I had a Happy Hacking keyboard for a while, and it had a nice feel but I eventually decided it was too minimalist. I sold it on eBay for nearly what I paid for it new.

I'd like to find a Model M to play with for a while; haven't used one of those since the 1990s.
Ahh, very nice! It's crazy to think how many of these little touches are hidden in OS X.
My favorite is the Kinesis Evolution chair-mount, but you can't get them anymore -- they stopped making them a few years ago, and even the eBay supply has dried up.

Conversation doesn't really need to go beyond this point. It's like asking "Should my woman cook and clean for me even though I beat her each day?" Really, the cooking and cleaning is not the issue in that conversation.

For a second I thought they are talking about exporting the mockup to an actual Android layout which made me come back and check for that option, only to not find it. They are just talking about serializing the mockup for later reference.
It makes a lot more sense to just run the Lottery as a raffle (pick one serial number from all tickets sold, or have a fixed amount of sellable tickets), but you can see how states are more enticed by the idea of open-ended ticket sales.

Illinois actually has true raffles a few times a year and they have always sold out before the drawing date.

agree with author 100%. If startups can attract users using a cookie cutter template with vague wording on what they plan on doing, then more power to them. I believe a startup should actually take a few days to think how they can best relay their product with copy, screenshots, customer proof, on their landing page, and get some genuine adopters.
Thanks for your reply. I'll look into it.
Neat idea, good work. Does it work by matching IPs?

Perhaps I'm being overly pessimistic but I see Twitter as this decade's Myspace.

Myspace was generational. A given (mostly teenager) demographic used it through the early to mid part of the last decade. It was, as we all know, supplanted by Facebook. There are many reasons for this, among them that Myspace (IMHO) sat on their laurels and that broader appeal (ie FB's cleaner page design rather than the Flash-swamped monstrosity that was Myspace) ultimately won out.

Twitter was and is touted as a means to:

1. send status updates to your friends (original idea);

2. disseminate news; and

3. follow "celebrities" (broader than the Hollywood notion of celbrities).

In spite of Twitter's stated 175 million accounts [1], how many uses does Twitter REALLY have? [2]. They don't state their 1, 7 and 30 day actives. As another example, Facebook's 750 million users is "monthly actives' [3].

Registered accounts and monthly active users are an important distinction, particularly for Twitter as it appears many people signup, try it out and then "leave". I believe that this problem is far bigger than Twitter has let on.

I simply don't see use (1) taking off. Twitter seems to be a medium for (3). There is definitely a market for that but I think it's a fragile one, easily replaced by something else.

That leaves (2), which is a complicated story. If there's two things podcasters (particularly former journalists, in the traditional sense) like to wax lyrical about it's the death of newspapers and how Twitter is changing the (journalistic) world, both of which are now boring (to me).

Twitter suffers from what I call "bubble thinking", much like Quora does. People in the Valley, in social media, etc think its huge. Normals have, by now, probably heard of it but won't necessarily even know what it is (let alone use the service).

My (unsubstantiated) feeling is that big brands haven't embraced advertising on Twitter. They're simply playing with it. Twitter advertising suffers from the same problems Facebook advertising does: unlike Google, which has the huge benefit of intent (you're searching for something, so Google knows your intent is to find out something about it, a natural fit for advertising), most people view such advertising as noise unrelated to what they're doing.

In Twitter's case it's exacerbated by their 140 character message format and the heavy reliance by users on third-party clients that Twitter doesn't control.

I know it's hip to not worry about how you monetize something in the Valley. While I generally agree with that sentiment, I think Twitter has gotten to the point where it's now a problem.

They recently had an $800 funding round. A profitable company doesn't do that. What I'd be looking at is this: where is that $800 million going? Is it largely paying out early investors? If so, run away. Run as fast as you can (much like Groupon).

I was passionate myself. Then a new non-technical VP was hired, and three of six directors were moved under the non-technical director the VP promoted. My title, and those of the others, went from director to Zweiter Beauftragter fur Administrative Fragen. Our job descriptions changed beyond recognition, for "flexibility", we were informed. My new supervisor informed me that I "solved my own problems"--a bad thing, apparently--and that I was "limited by what I know." I was required to attend unbelievably boring "change management" meetings, in which the entire department got to listen to the ephemera of Windows system administurbation and discuss the cleaning of digital bed pans. Whatever passion I had evaporated. I left a couple months later.
Wow. I'm floored. Thanks for your response. I'll keep it in mind.
I use a Lenovo Thinkpad keyboard. They're widely accepted as the best laptop keyboards, but also available as a USB device for desktop use. I find a short-stroke keyboard less tiring and like having a consistent experience across desktop and laptop. The trackpoint is very useful for keyboard-dominated workflows where the mouse is used only occasionally.

Some processing companies include interchange as revenue and some don't. If Square does, then they still have ~$110,000 / day in revenue, and what you're calculating is their profit. But you're still right that they have high variable costs because of interchange and therefore may not be as profitable as one might think with that revenue.

As an example, Heartland includes interchange in their revenue. "Heartland reported $526 million in gross revenues for the quarter... Interchange accounted for $365.2 million of second-quarter revenues."[1]

At Braintree we don't include interchange in our revenue, so our processing volume is higher than Square's, but our revenue is lower.

My favorite part from Bill:

> So I did the reboot because it INSISTED on it. Of course that meant completely getting rid of all my Outlook state.

The fact that you can lose Outlook state by a reboot doesn't seem to bother anyone. It doesn't seem to have dawned on MS or Bill that maybe saving the state as you go might be a useful thing.
I'm currently failing to install Lion, since it gets as far as the restart stage, and (from what I can gather) is attempting to create a recovery partition, fails, and thus doesn't install.

All workarounds I've seen so far seem to indicate that I need an external device of >13G which must be formatted in the process (making me exceptionally nervous about trying to repartition my current USB external backup disk)

So yeah, it's still not perfect.

Had an uncle in the industry (with wall street experience who was (re)starting an algorithmic shop for the first time in the late 90s). Sometimes I think I would've saved more time if I had stayed in the Bay Area and not gone into HFT (in Chicago), but I definitely appreciate the rigorousness of some of the mentors I had there.

I didn't go right into writing backend matching engines for HFT though. Took time. Maybe not ten years, but maybe something like five years to come across good mentors that insisted I relearn everything (and get into the thick of HFT).

One mentor I had used to say he was going to crucify me at my desk, etc. (somewhat jokingly) in response to code reviews. It's a little bit annoying, but good practice.

I definitely still make mistakes (I am somewhat absent-minded). But I've learned to build protection around code, and to make checks and elegantly scale in things like test cases as unobtrusively and quickly (but as carefully) as possible. So maybe I make a bit fewer mistakes than some of my colleagues without that background.
You could always ask them other questions you already know the answers to in order to measure that.
I use a Model M SpaceSaver: http://www.clickykeyboards.com/index.cfm/fa/items.main/paren...

The key feature is that Shift+NumLock turns the right side of the keyboard into a number pad (in hardware, no OS support required).
FWIW, the improvements are not that significant (based on the last time I tried the patch a month or so ago).
It wants the MAC of a public wifi access point (rather than one's own MAC).

The shorter distance to the mouse is one reason I prefer laptop keyboards in general. The trackpad is centered below the keyboard, and it's always in the same place relative to the keyboard, reducing the slight time it takes to find the mouse on a conventional keyboard setup.
Left-hand mouse.

It took a long time, but I'm mouse-ambidextrous now. It actually works really well to switch several times per day.

Also, the Kinesis Classic/Advantage has a button which toggles right half to act as a 10-key.
If you are hiring in a 3rd world country, be careful as the law is not with you. A competitor can buy your developer code and run away with it without you are not being able to do anything about it.

so yeah, in 3rd world country, to be passionate and motivated, money mostly talks. Sad but true
Yes, but having no HTTP connection is better than having fewer HTTP connections. If it's already in the cache (and the resource expire header doesn't signal resource expiration), the browser won't open another HTTP connection.
There is a lot of crappy developers that's true.

If you look at the serious pieces of infra inside the front offices for pricing and risk however, there are some smart people that have done some good software.

Quite often however those projects are degraded as stewardship of these projects is inconsistent, and long tenure is not always there, so you don't get continuity in terms of engineering talent.

Frequently this is due to the fact that IT is treated as a cost rather than an enabler of profit, and salary increases do not keep pace with the market worth of fulltime employees - leading to job hopping.

For the non-managerial part of the financial developer's career, it is often a better trade to be an independent contractor on a good daily rate with tax breaks, than take the chance upon fluctuating market conditions and bonuses.

As software developer bonuses are not tied to material outcomes like the front office but are generally more qualitatively judged, this leads to insecurity.

The developers that hang around for many years and end up being the stewards of these good systems that slowly rot, are quite often the ones that are incurious about contracting or moving, or have no better options.

We are routinely picking the top few percentile from the best colleges - the banks don't lack talent - but what they lack is management with good engineering discipline, and good projects sometimes turn bad.

For the professional developer who is actually skilled, this provides unbounded opportunities - it is often easier to make a really big impact with relatively little effort by pruning an overrun garden than rebuilding a very large amount of function points from scratch.

Finally, it is incorrect to say that version control systems are not used. Simply not the case.
Around 1999, my first Kinesis Classic saved my career. Switchover takes a bit of retraining of muscle memory, but I honestly cannot say enough great things about these keyboards.
It's already fixed. Thanks for reporting! =)
So you'd prefer a single market-maker to control price discovery rather than have several parties compete to do the job?

You can argue that /liquidity/ is fine if you have a small number of market-makers but price discovery (otherwise known as "value") is something altogether different.

To put it another way, I can get all the $8 hotdogs and $12 beers at Yankee stadium I like. The liquidity is fine but the VALUE isn't.
It's speculation to make this claim. The burden of proof should be on them. I'd need to see a benchmark showing that making a new HTTP connection (DNS resolution and all) for a single <100KB file is worthwhile rather than sending it over your already open HTTP 'keep alive" connection.

I was meeting some guy who have worked in ergonomics. His claim was the following.

If you sit down most of your life you likely will end up with back problems around 40.

Just standing up 50% of the time would hugely benefit and as he said standing up all the time would be the best.

I am contemplating whether to do the standing up all the time. So far I am doing 50/50.

Was thinking for those who like to switch 50/50 or some variation of that,whether it would make sense to create a little reminder app.

Would people be interested in that?
Nope. It was a new implementation by Tadayoshi Funaba (the ruby Date maintainer), but it uses a similar data structure to home_run, and performs about as well.
Added, thanks for the suggestion! =)
This most certainly looks interesting. Currently been experimenting with Adapt.js and this looks like a much better solution for my needs.
