" It produces profitable simulated results on historical data"

I understand this is an intellectual exercise, but for those considering going into algorithmic trading, those words are dangerous:

- what transaction fee model is being used? Almost all profitable day trading strategies trade too often that the profits and adverse selection reserve are decimated by commissions and taxes.

- have you tried to approximate the presence of your own trade? For example, if you sell a boatload of google shares, the price will start falling. Even with more liquid issues like AA it doesn't take much (5K shares) to rock the boat.

- Have you considered the spread? It's unprofitable to quote a penny spread on google or other high-dollar names (the SEC tax alone, roughly $25 per $1M sold, doesn't allow for really profitable market making without at least 3 cent spreads.

There are many more questions, and for each question there are hedge funds and prop shops that have lost significant amounts of money, or were driven out of business, due to an oversight.
I was once on a project which lasted about half a year. It was really tough work, in a foreign country, harsh conditions, bad management... People were nervous, and one day they found out someone had 12X their salary. It was me, but they didn't know it. I didn't know they didn't have same salary as me or close to it. I was brought in as a specialist, but even people higher than me had smaller salary than me (4X smaller). Situation was not great after that, but names were witheld. I always wonder how it would play out if they found out it was me, we were all on friendly basis.
Sure, that's an honest communication, but apparently not completely honest because their systems are still down.

" If someone works only 10 hours a week they should be able to afford small luxuries."

How? At what price? 10 hours per week even at $10/hour is still $100/week, minus some taxes - you're at... say, $80/week = max $400/month. How on earth can someone earning $400/month afford 'small luxuries' like a $200 tv? And the 'big screen tv' that was mentioned - I've never seen any (new) under $450 (yet). Not sure where you're living, but for someone earning minimum wage working 10 hours per week these are simply unattainable. Or, let me rephrase that - should be unattainable, because there's nothing left for subsistence.
Yeah, it might be fake, but it could also be the chance to work somewhere amazing. I have gone to a few jobs like this, where the job was fantastic, involved working on grid computing, traveling around europe. I did not have to fake enthusiasm, but I can imagine a lot of people would not have cared for it.
Did anyone else catch "as a business person, my mom says she feels like she's held hostage by developers". That seems... excessively hostile? It's a cute campaign, but I think it actually reflects poorly on her mum.
>> But that's not true, the amount of money is constant -- it just changes hands a lot.
> No it's not: https://en.wikipedia.org/wiki/Money_supply#United_States

Right. Governments print money all the time, but the total value of all the money remains constant, thanks to inflation. It's just a measure of how much power someone has in a society compared to everyone else.

> It's less of a problem of income distribution than one of wealth distribution. The key issue is that people with lower incomes accumulate assets that cost them money (house, car, TV...) while those with higher income collect stocks, bonds, rentable real estate property, all of which generate more wealth.

That's not given by God. Stocks didn't use to be money making machines and there is nothing that says they have to be. Stocks have been doing amazingly well since about 1980's because during the same time period wages have gotten a smaller and smaller share of the gnp. The ugly truth of the stock market is that for every winner there is also a loser.

"I think universities are completely obsolete. There’s very little that goes on at a university that can’t be done better otherwise. The biggest raison d’être for the present system is the security of the professor. Once you eliminate the obsolete structure and the emphasis on earning a living, people will go to the university because they want to use themselves and explore their wonderful capabilities. Humanity will carry on beautifully if you don’t mix them up with earning a living. We’ll make wonderful use of those buildings and all that equipment. They’ve been living on the idea of monopolizing the information, but now they see the time coming when the big idea will be to proliferate it and try to see that everybody gets to share it."

I've done exactly that, and very deliberately, with GrantTree. All salary and bonus information is available (anyone in the company can log in to the accounting system and check it, along with all the other company financials).

It does mean that there's some people you won't be able to hire, if they demand a higher salary than their peers and won't budge on it - but then again, I'm of the view that I'm better off not hiring those anyway. I think the benefits of having an open, trusting, transparent culture far outweigh any benefits a single individual can bring to the company. Someone who's willing to damage the culture of the company for their individual benefit is probably not someone I want in this company.

What are those cultural benefits? Well, for example, because we are transparent all the way through, this is also reflected in the very open and relaxed culture, and it then is reflected onto our clients - after all, your employees will treat your clients in the same way you treat them. Most companies are "open" in quotes, but then when you get to sensitive information they closed up, which sets up an uneasy tension. We don't have any uneasy tensions at GrantTree. That's a huge benefit to me. I don't like dealing with uneasy tensions and lying to people and hiding stuff.

It's important to combine transparent salaries with transparent ways for people to increase those salaries, in my opinion. If you don't, people will feel stuck (transparently so). But if you do, people will feel that there is a known path for them to increase their pay and they'll work on that path rather than try to ingratiate themselves to get a pay raise in private.

Any further questions about this - feel free to ask. I'll do my best to respond.

Staying in the flow is more important than staying focused on one problem -- that's more what I got out of the article.

Applying the digging metaphor -- keep up a good digging rhythm. If you get stuck in one hole, instead of losing your rhythm (and motivation, and flow), switch to work on a completely different digging job... and switch back later when you're getting tangled up in that one.

The metaphor starts straining there -- since if you hit a huge rock in this hole, it's going to be exactly the same when you get back -- but for more intellectual work, problems tend to simplify themselves when you put them aside for a bit, so this strategy can make you far more productive than "brute-forcing" your way through the problems on the first project.

I still dont get the drift about Ruby being fast enough.
Ruby is slower then CPython, PyPy, Lua, LuaJit, and literally majority of other popular dynamic scripting languages.

The argument that keeps being throwing up is that It is fast enough for most ( actually only for Rails related ) things and is mostly limited by SQL, but that is like saying my Toyota Prius is fast enough since the high way speed is limited anyway.

I meant most of the complain aren't really about Ruby getting LuaJit speed ( is that even possible? ) or JS V8 engine. Just at least it is on par with Python ( not talking about PyPy either )
I think there is a lot more to it than that. I have been to interviews which were almost hostile like the first one, and the opposite, where it was almost a conversation.

I do not understand people who do the first type. Why? The interviewee is the enemy.
For those having trouble with the EC2 instructions, I thought I'd point out that I think that the Archive Warrior[0] (which is much easier to get up and running on your laptop, etc) running over my tethered cellphone is my most performant client.

Yahoo don't appear to rate limit mobile devices / IP blocks as aggressively as everything else (probably because cellular providers tend to have many customers behind one IP).

I think the flaw in "MBA driven bull-crap" is an incomplete algorithm. You can only track what's being measured, and only if you understand what's being measured fully. Humans are extremely complicated creatures, so currently they're impossible to measure accurately, and to fully understand. The refined technology simply doesn't exist yet.

Smart MBA's will recognize this and adjust things accordingly, but this has to be embraced throughout the organization. One minnow is easily overlooked in a sea of fish.

--------------------

Personally, I like to measure companies based on how well they implement idioms from other complex professions, like programming. DRY, KISS, etc... The more repetition, the more unneeded complexity, the poorer the company is to work for (IMHO).
So, are you making money money with your Rego ?

A bad answer but an honest answer. I mean, until you work at a place, or unless the job is fucking amazing, there is no reason to pick one over the other. For 95% of dev jobs, there is no big reason.

You're right, we should probably just start 7 year olds out with assembly language and beat them with sticks. Starting them off with a fairly easy language that's widely widely widely used and easily introduces simple topics like variables, loops, etc is probably a terrible idea. Thanks for your consideration.
One of the things I always wanted to get around to while working for Google was to borrow some ideas from Gnus, Lars Ingebrigtsen's brilliant news reader for Emacs. (A rewrite of Masanobu Umeda's Gnus)

Gnus has a brilliant system for assigning a score to postings in all sorts of clever ways. You have the simple stuff, like assigning a negative score to a given person, but you can also do more subtle stuff like scoring up postings that are responses to your own postings. It also has various forms of adaptive scoring.

The score then influenced the ordering of threads, highlighting threads that need your attention and hiding threads and postings that you do not want to see. (Most news readers had a bozo-filter that could do the latter, but which didn't really do any of the former well).

What made Gnus such a great newsreader was that, with the use of scoring, I could spend 10-15 minutes per day getting an overview of dozens of active discussions I was having across a bunch of newsgroups. At one point the total number of postings in the groups I was following was around 6000 postings per day, and it took me mere minutes to get an overview of what had happened that was of interest to me.

The idea of scoring applied to RSS feeds would have been brilliant. It would have made following a massive number of RSS feeds a far more attractive proposition.

I still think that there is an opportunity to revive RSS and make it relevant again, but I would recommend that people interested in RSS readers have a closer look at Gnus first. RSS readers need to do a lot more than just aggregate and display feeds. There are some great opportunities in figuring out how to add scoring in a way users can understand. Also I think that harnessing social to provide additional signals that can be used for scoring would be neat.

Is there an RSS reader today that does any of this?
I've met some of those too. The solution to deal with those people is ruthlessly simple: don't hire them.
Google handling of Orkut just suck. Personally the features on Orkut are much more interesting than the ones in Facebook, but Google never fixed issues that existed since the platform inception ( for example there are no edit button to fix your forum posts )

Where "Christian" you can put whichever company grows along with it's API/code/lib usage and utilization by others.

I believe that can be solved by giving everyone the potential to earn more money if that's what they care about. Ideally, at least while the company is still small-ish, everyone has some kind of way that their work is directly connected to making money for the company. So allow them to earn a bonus based on doing things that earn more money for the company.

You might argue that developers are not that closely connected to the company's income (I can see how that would apply). But in my experience, developers tend to care about earning enough money but they're not obsessed about making large commissions, like salespeople are. So if we had developers at GrantTree (we don't), I would simply offer them the choice to move into sales if they prefer the money to the benefits of being a developer (which is a hell of a lot less stressful most of the time, let's face it).

Sure, that means that you'll need to find a new developer to replace them if they succeed in making the shift, but on the good side, you'll have gained a good, highly technical salesperson (worth their weight in gold), and if they weren't happy being a developer, they'd probably have left eventually anyway.

Even better, what we're saying is "50% test coverage is a good start, keep writing good tests and if the number goes up, that's even better." Targeting 100% coverage simply motivates using the wrong incentive.

It is a subtle, but extremely important, distinction.

I reread the post and I agree that the advice is also applicable to non-entrepreneurs (e.g. hackers, hobbyists). What became clearer is that his advice is to pursue multiple goals, not to juggle multiple tasks at once.
I was presenting at a tech conference last year and was trying to discuss the essence of PHP, and I accidentally uttered the phrase "php-ness". Accidental, it got a small chuckle, and we moved on (8:30am session time IIRC - not enough coffee yet). I'm glad someone didn't record it and sue the organizer or try to get me fired over it.
Exactly! It's maddening to hear there are better technologies and services than RSS yet no one can name them...
The battery historically was the most massive component. Letting it pop out of the chassis dissipated a great deal of the impact force, so the more delicate components were somewhat protected from the shock.
"The bulk of Google's revenue comes from leveraging the openness of the Web"

Does not compute. Google makes its money selling ads. Those ads appear mainly on Google's website, which is very much closed. Nobody knows how Google comes up with search results and why specific ads are shown.

"were there only Facebooks and Twitters there would be no Google Search because there would be nothing to index."

Google existed before social media: before Myspace, before Friendster, even before LiveJournal. When Google started, 'blog' wasn't even a word and Geocities was one of the most popular sites on the web. Social media is still a small part of what happens on the web. But imagine, were there only Facebooks and Twitters, surely Google would be offering ads there.
Designing an object to predictably disassemble into multiple parts helps soak up the impact energy. The fact that many cell phones used to break up when dropped was not accidental, it was a deliberate engineering decision.
Depends on how the execute this. If they turned it on like a switch I think it would fail. But it seems they are slowly allowing verified authors in G+ to affect search rankings. Slowly people will see this and want to get in on the action. Slowly people will migrate to G+. If you look at how Google has handled G+ you will see that is exactly what they are doing.
Wouldn't it be more effective to deploy a small parachute?
I think sales people are often overpaid, and developers underpaid. After all, the people creating the value and maintaining the product are the ones that are truly "selling" it. The sales people are just pointing people's eyes at what dev makes.
