That's cool, thanks. Basically, the ISS laser experiment was not stretching the bounds of the method at all.

Put a proper telescope at the receiving end, and it changes the game completely. It's simply amazing how little light modern telescopes are capable of detecting and measuring.

Note that your arxiv paper describes detecting a 50kW laser that is diffraction limited for a 10m aperture. That in itself would be a quite interesting piece of equipment to build.

Edit: Interesting - the abstract seems to have been mis-copy&pasted, with 60kW instead of 50kW.

I am one of the authors of Haskoin. We have had internal discussions on this topic. It was agreed that we wanted to minimize dependencies to code written in another programming language, which was the reason we did not choose one of the existing C++ crypto libraries, such as OpenSSL. My colleague Philippe, who wrote the crypto code, deemed the existing Haskell crypto libraries unsuitable. Hence we rolled our own ECDSA.

Apparently it's really easy to install Ubuntu [1] on a Surface Pro 3.

"...you’ll find that most things work out of the box. WiFi works, but only 2.4GHz networks can be detected. The touchpad on the Type Cover works, but the keyboard does not. You’ll need to activate the virtual keyboard in the accessibility setting to get much of anything done, and Ubuntu’s virtual keyboard is lacking in desirable features. There are some third party alternatives you can install, but the initial experience here will likely have you scrambling for a USB keyboard.

The pen works as a pointer and as a left-click when you press down, but because Bluetooth does not work out of the box you lose the buttons on the pen."

Why were you surprised? Did you look at the 42floors team bios page? One of them actually reads, "Also, accused of having a resting bitchface (RBF). She's working on it." Really.

What's amazing is not that 42floors dinged a candidate with "strong experience leasing SF office space" for wearing a nice suit to an interview (real estate professionals tend to dress well for obvious reasons). It's that such a candidate actually gave 42floors the time of day.
Think about it, wavelength (or frequency, they're effectively the same measurement here) determines how fast you can transmit those 1's and 0's. It's not slower, it's just that you can't transmit as much information in the same time period.

Also, laser light for Telecoms is not normally Visible, it's usually Infrared which has a wavelength shorter than Microwave radio but longer than visible light.

Another bonus fact; in a vacuum, Radio and Light waves travel at the same speed. However, when light travels down an optical fibre it is slowed down by the glass so Fibre Internet is actually slightly slower than radio.

This is just a sensational article. The fact that the total number of accidents increases with the number of drones flying is hardly surprising. There are standard ways to measure flight safety, for example the number of incidents per 100,000 hours of flying. To objectively compare the safety of drone operations to GA or airlines, we need to look at these numbers instead.

Having had a look at some resumes recently, I see some people who list every language / framework under the sun. I question how much knowledge they have of each of these. I would say learning Django alone to a decent level took me 6 months. I am still learning more 3 years later. If you claim to be learning 5 new languages a year, your knowledge of each can't be so deep.

I'm creating a MUD (text based multiplayer RPG) with Elixir using websockets instead of telnet. After reading the prior blog post I stripped out my account / character creation and converted to random URLs.

Game data like this starts out as being unimportant to the player when they're just dipping a toe, but as they get more invested it can become very important to them. I'm going to give players the ability to customize their URL to something more memorable / create a password to protect their URL / provide an email address to make it possible to reset a forgotten url or password. Those things will all be doable from within the game and are never mandatory, the player can decide when or if they care enough about their character to protect it.

As a bonus the account / character creation / login code was some of the worst code in the app so I was happy to delete it.

It sounded like part of his point was to get more comfortable with not always being goal-oriented and not always thinking that they have to have plans and goals. For some people, the compulsion to always optimize their time and do big meaningful epic things (including things like taking a month backpacking in the Rockies instead of using that month to lounge around and decompress :) can become so strong as to be oppressive. After many years it can actually suck the joy out of life.

samspot is dead on here, at least from my perspective. I am very private and have suffered from social anxiety for years. I don't use Facebook because I am overly sensitive to the reactions of others (no likes? everyone hates me and thinks I'm stupid). I spend far too much time thinking about what others think of me, so my natural inclination is to completely remove myself from public view at all opportunities. I don't use GitHub for this reason. I'd like to contribute and become part of a community, but I'm so terrified of being judged that I never step forward.

So I completely understand the author's attempts to go public. It isn't about being the next DHH, it's about overcoming the fear of rejection. I have been considering "going public" for years for this very reason.

intellectual humility is fake humility.

Seriously, humility is one of the most arrogant things I've ever come across. You do not ever "signal" and be humble at the same time, that isn't how people work.
Renouncing one citizenship without first acquiring another is a great way to destroy your own freedom of movement and generally undermine your own quality of life. Stateless persons are usually treated according to the amount of wealth they possess. As someone not particularly rich (by Western standards) getting free of the US requires chaining yourself to a less objectionable regime. As might be expected, the countries that people want to live in have stricter immigration requirements.

The "just leave" escape valve is thus not very effective whenever the pressure builds too quickly. Besides that, the smartest and wealthiest people leave first. Anyone left behind is less able and possibly less willing to defuse the crisis.

For most people, they have significant investment in their local community, with financial, social, and reputation capital built up over many years. Abandoning that represents a huge loss, and would require a proportionally large threat to even be worth considering.

I don't expect emigration to change anything, unless some other country miraculously changes its policy to out-freedom the US, and thereby suck all of its brains out.

As one of the few full-time sales people that hang out on HN...

Business to business sales (which is the usual code for high volume cold calling jobs) is a slog. It takes a certain kind of person to do it. I've done it, but never really liked it. I'm more of an enterprise sales guy for start ups. Maybe the variety of different pitches every week is a selling point for potential staff? I really don't know. I do now that you couldn't pay me enough to do the job :)

Outsourced cold calling (phone) is a pretty major industry in the enterprise space. It'll be interesting to see if this scales down to a feet on the street model.
The OP made the bold claim, "ProductHunt Is Quickly Becoming the Hot New Destination for Sourcing Startup Investment Opportunities", suggested that 206 investments "might have been sourced on Product Hunt", put together a meaningless table showing a handful of companies and the amount of time between their appearance on ProductHunt and funding (which doesn't speak to where these investments were sourced), and then at the end of her post noted that she had no evidence to back up her claim.

If you're going to make what amounts to a causation claim ("ProductHunt Is Quickly Becoming the Hot New Destination for Sourcing Startup Investment Opportunities"), noting at the end of a long post that you have no evidence of causation is kind of silly.
yeah, but the whole interview situation is completely unlike a work environment.
The real question is "why not?". Yes it could go to mars, but why go through the trouble when there's all those juicy resources right here? But even so, when it's done with the other planets, why not come back to Earth? Why not build a Dyson sphere to absorb the sun's energy? Oh, we'll stop it? Yeah, another reason to wipe us out to begin with.

Why not is a surprisingly difficult question to answer, and it comes down to 'care about what humans care about' which is itself unbelievably hard to pin down.

I just built a very simple version of this in about 100 lines of go, using http://github.com/disintegration/imaging for the image processing.

I was surprised how... latent downloading from S3 is, and how it didn't seem to matter if I was running on Digital Ocean or EC2, downloading the image from S3 was always the slowest part. (Digital Ocean was actually faster!)

It takes about a second to process an image, but it is cached in front of CloudFront similar to the article.

Any tips for improving the latency from S3?
I have seen some similar code. After authentication, a parameter was passed into the URL. Basically, if you had that token, you were logged in. Some user posted a link to their page on some site and included that token.

Later, the user complained about all of their photos constantly being deleted.

Photo deletes were GET-based and did not have no-follow. Google eventually indexed their logged-in link and was happily deleting all of their photos daily.

Fun times tracking that one down. (It was a code base that I inherited.)

I'm currently using Dropbox and sync all my coding folders (mostly Rails/Node.js/Go/C#). I'd be willing to switch if one of the other providers would have smarter folder exclusion (something like .gitignore or I would even take having to make a sentinel file like .nosync in every folder).

I'd like to exclude things like node_modules, build folders etc. It's gotten to a point where I have to disable Dropbox during development and let it catch up later otherwise it chokes up CPU at 100% doing it's hashing.

Any advice would be greatly appreciated!

Might fall under political events, but still relevant to the community here IMHO
Oh, I generally agree. "Cultural fit" was the reason my grandparents couldn't get into certain schools, clubs, organizations, or jobs. "Cultural fit" has a long and notorious history as a coded or indirect form of discrimination.

That said, company culture can very real and very potent, provided it's founded on professional and non-discriminatory criteria. That's why the burden of non-discrimination is on the company and its culture, not on the candidate.

What are valid forms of cultural-fit tests? ESPN, for example, gives candidates for many of its positions a sports-trivia test. This makes sense. If you're going to work for a sports network, you should probably enjoy sports and be generally knowledgeable about the subject. And ESPN, for its part, probably notices an empirical correlation between people who love sports and people who succeed in sports-related television.

Now, this sort of thing would be discriminatory if it involved any aspect that tested for status. Holding evaluative games of pickup basketball or touch football would discriminate against the physically disabled, pregnant women, and heck, just about any woman placed on or against a mostly male team. ESPN is welcome to participate in intramural sports game, or to hold weekend sports outings. But those activities cannot be used to evaluate employment status or candidacy, and an employee who doesn't want to participate should not feel pressured to do so.

Browser crashed too
Developing a moderately complicated plugins on Firefox and Chrome is a major PITA currently (not to mention that JavaScript is... somewhat moderately PITA to deal with as well).

I just wish that these vendors behind web browsers would put more effort on cleaning up their acts on the plugins development as well (stable and useful docs, tutorials, more tutorials, and mooooreee tutorials, sane development environment without jumping through hoops, better integration with IDEs and whatnot), not just building infrastructure upon infrastructure in which the development and deployment to the said infrastructure is PITA.
Genuinely wondering, why Chrome? IE11 has a really awesome touch UX, in the metro version, IMO. Did you try it and dismiss it, or not even consider it given IE's track record?
