> If all that is is their "entry strategy" then the strategy they are using is more complicated, which runs counter to your earlier assertion.

Not really, you need to have a position size strategy as well as an exit strategy, all are fairly simple and only a few lines of code. Given a bankroll, how much do you bet on any one trade (2% is trader standard, or if you're really aggressive half kelly), and given an exit strategy, i.e. a stop if you're wrong and an exit if you're right, just compute how much to trade based on the amount you're willing to risk on the trade to the stop position.

So with a 10k roll, you place trades that will lose $200 bucks if you're wrong and you let them ride until trend change hopefully netting $600 or more by the time it's over, perhaps lots more depending on how long the trend runs. Once that trade is safe, i.e. you're risk off, you start looking for another one and you build up your position size without ever risking more than your initial risk.

> It will move. But it needs to move in your favor more than against you, or you're losing money. There's no particular reason to expect that to be persistently the case.

Sure there is, markets aren't random, they trend persistently for longer than they should if they were actually random. The EURUSD was on a 6 month long downtrend this last year; that is not a random occurrence, that is a result of long term economic trends. If you're selling breaks of a running low, you'd have been shorting that all the way down; you need only adjust for volatility so you don't get knocked out on normal sized retracements and ride the trend down. You have to size your stops to adjust for normal volatility and allow the trend to carry you to a win and you have to tune your entry so you're already near an extreme against the trend so your odds are better, you can't enter blindly, but it doesn't have to be dead on accurate if your stops are wide enough. But wider stops require more capital to profit because you have to stay in the market longer to see your profit point hit if you're keeping a favorable risk to reward.

When the market isn't trending, don't trade it, you'll lose your ass in random price movements.
You're looking at this from a founder/company perspective. When I wrote that, and most of this post I was thinking of three things: The employee, the greater good (all of us, environment, etc - 'community' for lack of a better word) and the company.

So you could change that first sentence to read:

"Brain power and productivity arrive instantly where they’re needed with zero transmission cost [to the employee]"

Employee, company and community aren't mutually exclusive. Reducing commuting cost for employee makes for someone who's happier, healthier and has more time available which benefits company and community.

I'd say only considering cost-to-company is less effective and a narrow way to measure how well your work environment and policies are doing.

"if remote workers were so amazing, and had been so amazing in practice, companies would use them more..."

An argument that can be used against any innovation with a legacy alternative.
The point was that reasoned, articulate debate is possible (or at least, substantially easier) on sites without character limits such as Facebook (and I'm sure it's happened a few times); not that it'll suddenly be the norm if Twitter removes this artificial barrier. I am somewhat surprised I have to clarify this :/
True, but who is making the biggest margin as well. Rents play into this.

I basically agree with you, but the following paper makes a good case to keep some research going. Basically we already have at least one long-term (5 billion years!) non-solar energy source should all else be depleted.

For profit entities will never stop trying to skirt regulation. It's one way to get ahead of your competition. We just need to make sure that there is adequate disincentive to do it. Uber is trying to do an end-run around employee laws, and it should be cautioned that this is not acceptable behaviour.

Labor laws in the US are already some of the weakest in the world. The US is the only developed country with employment-at-will, All other developed countries use a just-cause model. Due to at-will employment, you can be fired for wearing the wrong shirt to work in the US.

Uber wants to jettison even these weak protections and go totally unregulated. This would be fine if the other party was in an equal position of strength (i.e. another business). Employers always have the upper hand, and therefore must be subject to regulation to level the playing field.

Smart Luggage Hacked – A detailed component level review
This is a great comment, thank you. I would have naively just thought of IPO and other stock mechanics as the 'big idea' many investors are running towards. That there is a churn of the money was unknown to me. However, these rents are siphoning off that churn at a much higher than normal rate. Additionally, it is changing the culture of the Bay, making future start-ups less attractive there.

JOOC, what is the CCA rating? I don't recall seeing it in the comments.

There aren't many of us who run winches, but thems of us that do want quite a few (650 CCA is not uncommon, and some winch manufacturers recommend deep cycle batteries like the Yellowtop Optima).
My understanding is that they are working hard to build APIs that will let Retsly power the next zillow, and that there's support for that internally. Time will tell!

Thanks for the feedback! On the spectrum from "iOS" to "airplane cockpit", I think GitHub is trying to be iPhone, but I think git has enough inherent power (like an aircraft) that you leave a lot of functionality on the table if you constrain yourself to a "no training required" interface. It's certainly something to aspire to, though! If there's anyone out there who thinks they can clean this up, I'm always looking for partners :) Based in SF, open to remote collaboration, contact info in my profile.

In general, probably not. Any optimization the game engine uses could also be used by browser engines (they already use DirectX/OpenGL, for example). CSS is just plain complex.
You should consider distilling your pitch into something more digestible for consumers. I had to reread those 2 paragraphs twice and I still don't fully understand what product or service I'm supposed to buy into.

Another of the SOAS intake at that time was Bernard T Smith, an RAF officer, who was posted to Japan in 1946 to take part in the rebuilding process. Bernard was subsequently involved in the UK computing industry. His paper on a general purpose query language, SPECOL, is interesting to read today given it was published in the 60s. (http://comjnl.oxfordjournals.org/content/11/2/121.full.pdf)

(My company published a Japanese translation of his 1946 memoirs and I had the very good fortune to meet Bernard. Sadly, he passed away last year).
I'm not sure why my comment got so downvoted, that's kind of weird as I was just stating facts.

Absolutely the average buyer of a Camry is not going to care about this. But that wasn't at all my point. Some cars (more often in Europe/Japan where driving is more fun because they have corners), take weight seriously. I think car manufacturers might take this option seriously in their sport divisions.
The problem is you can't explicitly tell a browser to fetch a cookie from cookie.example.com - and when you have multiple subdomains which rely on the cookie, plus analytics software which sets it for the whole domain, you can't do that.
As an ex C++ programmer who did embedded telecom (amongst other things), I've transitioned to web development. It's not really that different. In fact people with embedded skills can do very well because things like memory management and performance optimisation are very important in web development. Often people with actual experience in that area are in short supply.

The main difference on the downside is a plethora of frameworks that often constrain your design badly. Of course, on any large project there is always a way to do things, and it is not always pleasant ;-) So it's not really so different. I also had to learn quite a lot about databases, something that I shied away from in my earlier days. Again, many frameworks try to shield you from database details, but they bugger up the object modelling so badly that you are much better off being quite aware of what is happening under the hood.

On the plus side, code bases are generally very small. We're talking having to maintain small 10's of KLOC (and very often less than 10k code) as opposed to 100's of KLOC. I wouldn't say they are toy problems, but they are definitely on the small to medium size. You can pretty much understand all of how an app works. Frameworks often bring the total code size up to above 100 KLOC (yes, I have spent some time debugging Rails ;-)), but again, it's not something that would scare a seasoned dev.

My main pleasures are being able to work with 100% free software tools from back to front. It's truly awesome to be able to debug and tweak anything I want. For frameworks and libraries, no longer do I have to depend on marginal documentation to see how something works -- I can just read the code. This is a massive plus.

For me, the acceptance of unit testing as a normal development procedure has been wonderful. Not all web devs subscribe to it, and very few do it well, but it is at least a mainstream concept. Also the tools available for TDD are really great. Rspec style tools (including Jasmine) are worth their weight in gold.

I think the biggest surprise for me making the transition was that there is a huge amount of complexity in web development. Yes, there are lots of people who do web development as a kind of paint by numbers, but honestly I've seen those kind of devs everywhere I've gone.

If you are looking for a change, I wouldn't rule web development out.
Niantic Labs splitting from Google
Funny how much things change in a couple years.. about 4-5 years ago, I built a gallery view, that had scrolling areas, that worked the same as the video mentions (only loading the next block)... what's funny is the css transitions were working poorly on some devices at that time, so it was disabled completely. :-(
Game engines and browsers have radically different architectures and performance/productivity requirements. Computing polygons is basically applying one function to an array of values and is delegated to the GPU, so its no wonder they easily reach 60 FPS with hundred of thousands of polygons per frame.

A better comparison would be against the performance of game logic, which in a game engine can easily become the bottleneck from all the conditionals, random memory accesses and sequential dependencies. And even there they don't sit on nearly as many layers of abstractions as a web page does.

This comes at the cost of productivity; building a web site is a few orders of magnitude more productive than using the latest game engines. Of course, sitting on the DOM and its many quirks as well as its reflow/redraw cycles can make it harder to reach 60FPS in the browser.

But at least you're saving yourself from a world of low-level pain.
> The saddest thing about Hacker News is that we all get behind radical things like FOSS (Bill Gates called it un-American) and Snowden, and fight SOPA and NSA violations of privacy, but because too many of our salaries depend on advertising revenue, our cognitive dissonance blinders go up lightning fast.

I'm curious how one would handle accessibility with a WebGL UI. Is generating a parallel vanilla-HTML version the only option?

I suppose you could progressively enhance your HTML version to override certain DOM elements with WebGL UI, but I have no idea how modern screenreaders would handle it.
What brought you two together? Why do you think you'd be good partners?

Maybe examining your cross-over of interests, abilities, knowledge, etc. will make something pop out.

Just start building SOMETHING. Give it a go, come up with a tiny idea and see what comes from it. Without knowing your abilities, etc. it's tough to know what your areas of interest may be.
Congrats to you and your friends, but that's nowhere near the average (50th percentile) case.

Out of my friends that graduated with me, in the set of {Google, Microsoft, Amazon, General Dynamics, AMD, Intel} employers, no-one, and I mean no one made above 90k starting. These people all graduated Suma Cum Laude (>3.96), with >3 years experience on average through internships.

No one should ever assume their counterparts are making anywhere close to them.
Salary depends highly on where you live due to cost of living. Starting salaries in Seattle for example were around 30% higher last I checked when compared to much of the Midwest.

If you make $80k where I am, I would be expect the same person to make around $105k in Seattle. I'd wager the person you replied to is also somewhere in the Midwest.
those wankers should work on getting diffs to actually show on their site.

hate when i have to code review some contributor and the site just says "oh, i will not bother showing any change on that file"... so i have to download their branch, run diff on the awesome `meld`, which kicks their visualization anyway, but then the only good thing about github: inline comments on code reviews... goes away. i have to either email or add lose comments on the code review panel with what i think.

but hey, now we can have the same crappy experience on (selected) desktops! hooray! well, at least you managed to get me to write an offense on a public forum. that is something. you wankers.
Game engines don't even go nearly that high-level. I see GUIs implemented in C++ more often than in scripting languages, and when they go that route its usually LUA without any declarative markup whatsoever.

Everything is a tradeoff, if you want the ease of HTML+CSS then be prepared to pay the performance hit, and if you want lighting fast GUIs, be prepared to pay the productivity hit.

Nikon is a startup?

The camera market is dominated by big companies. And not only that, many of those companies were actually also big film camera companies. Obviously there’s Nikon and Canon. Sony (which has been coming out with some wickedly cool and innovative digital cameras and certainly worked its way up to become a huge digital camera company) is not an analoge camera company, but it’s also not a small company.

The biggest disruption to the (low end of the) camera market have probably been smartphones and their cameras. (The market segment of cheap point and shoot cameras is practically dead and camera makers have already moved on to new and certainly more exciting products, targeting a very different audience.) That’s chiefly Apple and Samsung (as the biggest drivers of bringing smartphones with good enough cameras to everyone), certainly not small startups.

Even the hippest of the hip current digital cameras tend to be made by some really, really old companies that have been making cameras (and analog film!) for ages, namely Fujifilm (it’s right in the name!) and Olympus.

Selling cameras is still dangerous terrain and I think it pays off to have great ideas and to know your audience, but some very old and very big companies have been quite excellent at doing that, actually. Of course, all around them there has been lots of death and destruction (including Kodak), but that doesn’t mean no one made it.
All the citizens in LA will pay for this "savings" later with their lives, child defects, miscarriages, breast cancer, colon cancer, and more. $250,000 should be sent on fixing all the water runoff problems. This will save more. Every time there is a 10 minute rain in Los Angeles all that water goes to waste. The practice of testing out HDPE plastic chemical balls out on the public's stomachs and kidney's as lab rats is just intolerable and all the people at the top involved in the decision making should be ashamed of themselves. They are complicit in coverup, poisoning, and conspiracy and I can't wait to see the Class Action suit form or better. These crooks should be in jail.
My point is about the disregard of the significance of the Fukishima accident. You must include that in the analysis.

This was written in 2011, and Fukishima has been continuously releasing radiation ever since.

I'm not arguing in favor of any energy source that damages the environment; nonetheless, I would prefer we acknowledge risks where they exist. To not do so, would be to send us down the path of possibly less safe nuclear facilities.

Depends of your platform, shader complexity, the number of GPU context switches and the number of sync points.

Mobile devices for example still have a hard time going over the quarter-million mark and thats assuming the GPU is near 100% usage, which in reality is probably closer to 60%.

Carnegie Mellon, GE Ventures bringing robotics accelerator program to Pittsburgh
It's not just Redfin agents: a surprising number of licensed agents have trouble with basic tasks like communicating via email and filling out contracts. Since we work as a team, we've built a vast amount of institutional knowledge over the past 5 months and there are no individual, inexperienced agents representing our buyers. We're also automating most of the offer submission process. This means that we're more responsive, more articulate and more accurate than the majority of agents. We also have the privilege of working with smart, serious buyers. We can honestly say that most agents have been happy to work with us and treat us like any other brokerage.

The most important thing to understand is the seller decides which offer to accept and that decision comes down to price & terms. The best offer always wins. 100% of the time we've submitted the highest offer, it has been accepted. Our offers are clean and our buyers are able to pay more knowing they'll get a significant refund. So far, so good.
Understandable... I wasn't really even speaking specifically to density, so much as some room for growth. It took Phoenix a long time to get the highways we do have in place. Even finishing out the I-10 in phoenix was a lot of big work.. the 101/202 work was interesting (never completed regions meant to go through reservation lands). And widening the US-60 was pretty interesting as well. It overlapped bidding for the stadium, so it seems that they held up the process to reduce the chances of Mesa or Chandler getting the bid.

I'm not saying it's a great example, just an example of a decently sized city that isn't locked in and could be a growth area. Right now, I try to live fairly centrally, but that puts work that is closer to the edges of the area out of what I consider a reasonable commute for me (I won't go much over a 30 minute commute).
I don't like this 75% full idea because the miners would virtually be REQUIRED to pad out blocks with trivial transactions if they don't have enough on their own. To not do so would leave hashing power idle.

A simpler solution would be to require that blocks are always 1 MB (or whatever) in size, and that they must be padded out with 0xDEADBEEF or whatever if the block can't be filled with transactions. This way all blocks will take the same amount of time to transmit, and there's no incentive not to include a transaction of any fee if what it's replacing would just be bad data.

I'm not saying I'm in favor of this proposal necessarily, but it works better.
I had a terrible gig there too! It (BTeV) died young.
Do you really think that the number of full nodes has been dropping because of the 1 MB block limit though? Not for other reasons? Is it really so onerous to run a full node now that the average computer cannot handle it?
