Skill? I'm putting up trades as an investment. My money can't just sit around in a bank account forever, it needs to be invested to make actual gains.

All the hedge-fund managers that claim to have algorithmic trading have extremely high expense ratios. So its cheaper if I made trades myself.

I mean, its only $7 to execute a trade off of Scottrade or E-Trade. While buying a mutual fund with algorithmic trading will cost you like 50 to 200 basis points per year.

Yeah, its cheaper to trade in the raw or to just buy SPY or Vanguard funds (which are passively invested without algorithms)
Right now Keras is your best bet for most deep learning tasks, and Caffe is best for image processing (i.e. convolutional neural networks). Keep an eye on tensorflow though because it may come to be the gold standard over the next several months to year.

Edit: Btw, François Chollet, the author of keras, made the following tweet this morning: "For those wondering about Keras and TensorFlow: I hope to start working on porting Keras to TensorFlow soon (Theano support will continue)."

It looks like to me the big win here is that this is a ML library just like all the others, except that the code is not written for a specific type of processor (GPU versus CPU), nor is it written for a specific compute level (desktop, server, phone). It's target is to be a general purpose ML library. This should have the affect of getting ML solutions into useable applications more quickly, since you don't have to develop on one platform, then port to another. It just works everywhere. Best guess on my part based on what I'm reading on the site.
You've just described a ballocket. You launch a rocket from a very high altitude balloon.

You gain nothing from the height, because you still need to spend ~10km/s getting up to orbital velocity, but you don't have to push your way through the thick lower atmosphere any more. Rockets don't work very well in atmosphere, so you do get fuel savings due to more efficient engines.

I don't know if this has ever been tried for real.

Ask HN: Ask current co-workers for references?
Hi,

I am interviewing at a company (Company A) that I like very much. They want 3 references.
I like the company (Company B) I currently work at and I think everybody (including technical leads) likes me. It's not that I dislike working there, it's just Company A is a better opportunity.

However, nothing is sure in job-hunting and Forbes magazine recommends you not list your current employer as a reference. It signals you have one foot out the door, and there could be repercussions for that. Needless to say, if Company A decides not to move forward with my candidacy after getting references from Company B, I would be in a very precarious position with Company B.
I am in the early stages of my career (company B was first job out of my undergraduate degree) and I am not a proficient network-er. I did two internships, but I have lost touch with my co-workers from those positions. Those internships were on small projects and were in electrical engineering -- and not reflective of my current software skills or interests. In fact, knowing what I know now, the work I produced during those internships was rather immature (hey, I was learning!).

During my undergraduate degree, I was a low-key person and I doubt many professors remember me. And again, my coursework was in EE and not related to work I would be doing at company A.
IF they remember me at all, references from past companies and professors would say was I am a good worker and not a disruptive employee. That's all.
Has anyone else been in a similar situation -- what did you do and how did it turn out? What should I do?

P.S, I hate the reference system. It seems like a holdover from a bygone era.

> Why is it unsurprising?

We'd have to imagine what is being counted behind the former and the later. Behind the former ("Anti-China trolls", that is) at the moment we have just one specific example brought to our attention. Behind the later ("Russian trolls") is anything anybody understands as such. It appears that the journalist who wrote the article we discuss here considers every author of some pro-Russian opinion as a troll (according to the article kaitai linked to http://kioski.yle.fi/omat/this-is-what-pro-russia-internet-p... ). So there you have a lot of ordinary people who could actually be Russians living in Finland. Or if we extend that to other languages, we also get the people who aren't necessary native speakers.

Then we have the people supposedly working at some "government site which pays people to write comments" (as linked by zorf, http://kioski.yle.fi/omat/at-the-origins-of-russian-propagan... ) being paid some 600 EUR a month, who again are almost certainly not the native speakers and probably aren't motivated too much to care ("we'll lower your salary because you screwed up the grammar on some of your posts").

So we can't expect grammar(Russian trolls) to have a high value, and the grammar(Anti-China trolls) is based on a very small sample. That "proves" the current state of the given inequality.

I also hope that this "derivation" also illustrates that naming names ("Anti-China trolls" "Russian trolls") is actually a wrong approach to learn anything about anything. See:

It's a slick looking video, but what about reentry? It's not that hard to get a ship up there (the X-15 was flying to the edge of space 50 years ago), and launching like a jet plane obviously has many advantages over rockets, but when it comes back down it's going to hit the atmosphere at a pretty high velocity, unless it's carrying enough fuel to gradually lower itself back into airspace where the jets can kick in. The craft in the video does not appear to have VTOL capability.

But, if they can solve such problems, great. I'm thinking that eventually we'll have some kind of electrical or hybrid mass driver (catapult) system for getting non-human cargo into low orbit[1], much cheaper (and quieter) and obviously could accomplish many launches a day for one-way missions.

You could get a large space station or interplanetary craft up there rather affordably using this approach. Specialized reentry vehicles as well. Launch the parts cheaply, robots assemble the parts in orbit, then launch the humans expensively.

All of those places have international airports except Knoxville, Richmond, Tampa, and Alabama. My point is mostly about having sufficient population density that an international airport is justifiable for the region, and that spurs sufficient mass of high quality information-centric jobs rather than primarily jobs low on the capitalist value chain. To further elaborate and simultaneously move the fence posts (but was part of my snarky intent) is that the tech jobs that are in these places aside from mobile software are almost always ones people on HN overwhelmingly do not want. These jobs are disagreeable from either an ideological perspective (defense, oil) or ambitious career perspective (industry-specific CMS apps, subcontracting support / maintenance on legacy applications, outsourced enterprise J2EE development, IT).

To me, the equivalent of "there's tech jobs all over the place in the US" is "there's jobs all over Craigslist, why are you complaining about lack of jobs?" Trust me when I say that most of the jobs I've seen outside areas with strong tech sector presence are likely not very good "tech" jobs. There's absolutely exceptions, but they are oases in the Sahara desert to me.

This is bananas. I'm a cancer survivor and I've administered hundreds of job interviews; I guarantee a large part of the difference in callbacks, if not the whole difference, is down to the combination of resumes and hats. Explaining a gap on your resume, great. Wearing a hat with "CANCER SURVIVOR" on it to an interview, ok, a little unusual, but whatever. Doing both? That's weird—not because it has anything to do with cancer, but because the applicant is putting so much energy into driving home an irrelevant point. I'd feel the same way if you explained a gap by saying you volunteered at a sloth rescue in South America (which would be awesome) and wore a hat with "SLOTH VOLUNTEER" on it (which, combined with the gap explanation, would be a bit much). It just screams "I have no idea who I am so I've constructed a fragile identity around this one aspect of my life."

Your site charges $600/year. That's 6% of a $10,000 portfolio. Do you think it can make a 6% gain in a year after taxes and inflation to cover its costs for that size portfolio? 6% gain is about the long term average of the S&P500, after inflation, so you're proposing doubling the market gain.

Just another symptom of dehumanizing work-life balance as promoted in the US companies. People feel like they need to get a leg up on each other in order to retain jobs and be promoted within jobs, so they make themselves available for work purposes when they are not being paid. Effectively, people compensate for the wriggling anxiety of an "unfulfilled" work obligation (an unanswered email received after hours) by giving away their labor for free (answering the email despite not being paid during that time period to do so). I think this is also why people may claim that they enjoy or don't mind answering work emails after work; the reduction of anxiety after tying up an email provides a tangible upward delta for emotion. I am of the opinion that 99% of after-work emails would be eliminated if employers had to pay for the hour-block during which employees are answering emails.

"But when asked what aspects have the most negative impact on work-life balance, work emails ranked rather low at 18 percent—topping the list were bad bosses, working after hours, and employers being inflexible about vacation."

Ah, the article is pretending that answering emails after hours isn't working after hours. They're the same thing, because thought and communication about details of work equals work. Bad bosses will tend to email after hours as well. Employers not respecting the majority of their employee's time (which is spent outside of work) is also closely related to being "inflexible" (not respecting the contract) about vacation. I think the article could have easily said that working conditions and labor rights in the US are extremely poor rather than pretend there is something magical about answering emails after hours.
Huge increases in R&D and marketing expenses, mostly.
That's grounds for job-search in my book.

Vacation is a form of compensation and if a company can't respect that then they aren't worth working for.

Subsequent to learning the language I immigrated to Japan, worked in a Japanese company for a few years (not recommended), married my wife (highly recommended, but sorry, she's taken), and in general built a happy little life here for myself which would not have happened absent learning the language.

If you have a little bandwidth to study Japanese prior to coming you'll get the highest bang for your buck from drilling self-introductions and basic conversations ("$ITEM kudasai.", "Yoroshiku onegaishimasu", "$LOCATION doko desu ka?") until you're blue in the face. Knowing just hiragana and katakana is of limited utility for navigation, since the places where it suffices will likely be English-friendly.

> Marriage is a strictly defined cultural phenomenon meaning a relationship between a man and a woman with the original intention to continue the family by having kids.

This is wrong in so many ways; "marriage" is a concept that exists in many cultures with many different different understandings, and those understandings have historically been fluid over time even within the same culture. Its most consistently a property arrangement between the parties; in the West its been separated from an essential intent for procreation for quite some time, though there are religious subcultures within Western societies for whom that may remain more important than it is in the broader society.

I have been a starcraft player for almost 2 decades now and I never really cared about the story or background to it. What I cared about is that it combines elements of some of my favorite strategy games into a single medium. I often say that it has elements of chess, poker and reaction based games like first person shooters.

It is like chess in that it is a game of strategy and board control, army movement, identifying what your opponent is planning and actively countering it, identifying weaknesses and exploiting them.

It is like poker in that is a game of imperfect information. Unlike chess I cannot ever see the entire board in starcraft, only the pieces I have scouted and as soon as my scout leaves that information is now outdated and assumptions have to be made about the actions of the opponent since I last had accurate information. Poker is similar in that you can never have 100% certainty of what your opponent may be holding, there is always that knowledge gap and great players can exploit it.

It is like first person shooters in that is it reaction based, the person who is able to more efficiently process the information they are receiving and make correct decisions about their course of action can execute faster and have an exponential return in terms of tipping the scales in their favor. This applies to many things such as base building, army building and micro mechanics during army engagement.

I've been a fan for so long precicely because these fine strategy details and forced decision making make an excellent filter between the good and the great, the great and the elite. Watching the elite play is comparable in my mind to watching chess grandmasters battle only in real time and not turn based where their perceived life is on the line and one slip up can cause instant death. It's that great adrenaline high, not the background story, that has kept me so engaged for so long.

>You solve the counterweight problem by also extending a cable outwards from your launch vehicle, so keeping the centre of gravity still

I don't follow. If you didn't do this, wouldn't your centre of gravity still remain still? Just start at geostationary and make sure you have enough mass to act as a counterweight already on-ship (doesn't have to be in the shape of a cable). The center of gravity will remain in geostationary, the cable will reach the ground, and the ship/counterweight will end up at just the right height to balance it.

FYI for all the readers here: Carbon nanotubes won't work, the phonon effects (lattice interactions) in that very large crystal usually add up to break them after a few cm. Think of it like like a very narrow and very long tube half filled with water. There are vibrations along the length of it, some big and some small in amplitude. When those random waves in the water tube interact, they can add up, sometimes so much so that they break the tube. I know that is now totally correct, but that's the gist.

Sure, neither totalitarianism nor democracy are binary things, and there are no razor-sharp definitions. I'm sure you can find examples of those things in many countries that are generally considered "democratic". However, in Putin's Russia this is common practice and happens on a regular basis (with the exceptions of invading other sovereign states I guess, which has only happened a couple of times), which is why I don't think it's controversial to call Russia "totalitarian".

Attention all iOS developers
Since most of the app/future apps will be adding location based events, we have just finished building an SDK that will allow developers to easily integrate the SDK and use it to set notifications they would like to send out based on users proximity to an event / place / person.

This will work with the user's consent; the SDK will even work when the app is brought to background or killed by OS (which is a HUGE problem for iOS)

Along side - we've developed an very simple associated dashboard for visualization that will allow you to see users location at any given time.

We're currently in the crowdfunding stage - will charge developers $15/month to start of with, when the website will be ready, new users will end up paying around $29/month.

Please let us know if you are keen and would like to discuss further.
