aquark··on Ask HN: What sites do you use to find contract work?
From the front page testimonial:

> in less than 5 minutes the project was fully spec'd and underway.

Honest question: why would I need a top '1% developer' for a project that can be fully spec'd in less than 5 minutes?

aquark··on Uber Using Driver Phones as a Backup Datacenter
But the driver is served by this -- the driver wants the Uber platform to be scalable, available and ensure the 'successfully customer experience' the article refers to, so that they can continue to get paid for providing the rides.

Now, if Uber were offering a free 'lol cats apps' on the app store that surreptitiously ran this protocol in the background of unsuspecting users I think it would be a different case, but running technology that supports the goal of the main app doesn't feel out of bounds to me.

aquark··on Subscription iPhones
Likely since they will still be high end phones, but as a trend this would suppress the price for used phones and just pushes the problem down the chain.

The people pikcing up those used phones are likely getting rid of a slightly older one at a higher frequency now and that will still generate more e-waste.

aquark··on Ask HN: How much money did you make from a mobile game you developed alone?
For discoverability you should make the rules accessible front and center on the game page.

I just clicked through and spent a few minutes clicking around ... I couldn't find the rules anywhere without clicking through to Wikipedia.

aquark··on Amazon Underground
Maybe ... but it hugely depends on the per minute price Amazon are paying.

The same thing could have been said about streaming music services and yet many artists seem not too happy about the per play $ they get from Spotify & ilk (though they are probably bound to say that regardless to some extent)

aquark··on Ask HN: JavaScript framework that I can use “right now”?
> I'm (literally) having nightmares about a JS bug I won't be able to solve > since it's so many moving parts

I am similar, writing the back end was easier ... front end not so much. I hated having JS bugs due to stupid typos and less than 100% code coverage in tests.

Switched to Typescript for the front end and things became much better. Doesn't have to be 'all or nothing' either, I still have some JS glue for interacting with some libraries and more dynamic bits, but generally everything is Typescript and feels much more solid.

FWIW the stack also heavily includes KnockoutJS, DataTables, Backbone's router & a smattering of JQuery plugins for this and that.

aquark··on Ask HN: Adjustable height desk recommendations?
Just bought one of these for home last week $593CAD + sales tax (~ $457USD)

It is certainly good value, and a fraction of the price of the one I had for work a few years ago (different brand totally). It can feel a little flimsy/wobbly when raised, but certainly not dangerously so.

aquark··on I am an 18-year-old techie/student. I have leukemia and need your help
I had the wonderful opportunity to donate this way earlier this month. It was totally painless (modulo a couple of needle pricks) and just required some time hooked up to the machine (~6 hours) and a course of drugs beforehand to boost stem cell production for a few days.

For the benefit it can bring someone it is a total no-brainer decision, and I'd do it again without a second's hesitation if necessary.

aquark··on Ask HN: Would you move to Montana to work on a startup?
Thanks for the great info.

We are ~10Km from the nearest village that likely has decent bandwidth, though no idea on the backhaul available from there.

Still 10K @ $30 (AUD/CAD)\m would be $300K+ to put it along existing hydro infrastructure. Wonder what the likelihood of getting 100 households to put up say $3-5K in installation costs would be? That would represent a decent fraction of those reachable along that stretch, and those nearer in may already have DSL.

aquark··on Ask HN: Would you move to Montana to work on a startup?
Agreed -- as someone living semi-rural (rural, but not middle-of-nowhere) I've often wondered about the economics of a fibre rollout, our only choices at the moment are very pricey wireless (for the level of service)

But not in a position to move to Montana!

aquark··on Greece to Default on $1.73B IMF Payment
It's a nice thought ... but €3 each covers the immediate payment needed.

Total Greek debt is €323 B [1] and there are 503 million inhabitants in the EU, making 'pay-off the debt' more like €642 per inhabitant

For context total EU sovereign debt [2] is €24,415 per inhabitant

aquark··on Ask HN: What are you currently working on?
> If you get into Google, Facebook or Palantir, we’ll refund 100% of tuition. No catch.

Seems kinda backward to me ... we'll teach you how to do this well, and if it works we'll refund you?

I get you aren't the only variable at play, but saying you'll refund if they fail the interview would be much more compelling! (But economically unfeasible I'd guess)

aquark··on Ask HN: Unpaid internship followed by unpaid work with equity. I'm a student
One other thing to think about would be intangibles the startups can offer vs open source:

* how good are you at self-motivating * what chance is there of being mentored at the start up? * will the CEO provide a good reference later one: a human reference likely beats pointing out the open source contributions in many jobs in the future

If you are going to work for free anyway on open source then make sure you have the dedication to actually do it.

Being more directly accountable to someone may be a benefit.

Good luck ... it's a tough call!

aquark··on Show HN: Onboarded – User Onboarding as a Service
There is something a bit ironic about a web site which claims to be 'the most effective way to communicate with new users' showing me a YouTube video to explain what they do ...
aquark··on Tesla Energy
re 1: part of the benefit of solar locally is that the rate you get for pushing power back into the grid is way in excess of what you have to pay to pull it out.

Whilst storing it for your own use later makes sense in theory, it doesn't work with the current economics

aquark··on Ask HN: Am I searching for jobs wrong?
I agree with letting the interview know you are interested in their company. Inquisitiveness is a key character trait we look for and asking intelligent follow up questions is a great sign rather than someone that has just thought of a list of pre-canned questions beforehand and is going down them.

But I wouldn't view letting on about other interviews a major problem -- knowing there is some competition both ways isn't a bad thing. I want great candidates to work for us, but I also know great candidates have choices.

aquark··on Patterns widget for sites
Nice work! I think this could definitely be expanded and sold as a standalone component
aquark··on FoundationDB's Lesson: A Fast Key-Value Store Is Not Enough
That's a good breakdown.

In this case though FoundationDB's KV store was order preserving. The API supported (& efficiently implemented) ranged reads, not just individual get's.

Implementing layered architectures always looks good 'on paper' but the details often throw up performance issues that are hard to deal with without punching some holes in the abstractions.

In this case it seems that relatively few companies had a need for a massively scalable ordered KV store, and the whole SQL layer was an attempt to bridge the product to a wider audience. It would be fascinating to hear more of the story but I suspect that will never escape now.

aquark··on New hubiC offers
I'm paying with PayPal automatically ... I get an invoice and a few days later they charge my card through PayPal.

The system could definitely do with an overhaul though the wording in some places was very confusing.

aquark··on Can the world please standardize passwords?
If you have higher security accounts which have gmail as the contact email, then the gmail account should be treated the same.

Breaking into gmail gives access to many password recovery mechanisms.

But I agree for low priority sites: my password across many forum sites is the same and very low entropy. I really don't care to think more about it!

aquark··on Apple Acquires FoundationDB
community.foundationdb.com is a little more informative ... not much but a little.

"Thank you for your support of FoundationDB over the last five years. We’re grateful to have shared our vision of building the best database software and we strongly value your participation in this community. We have made the decision to evolve our company mission and, as of today, we will no longer offer downloads. If you have any technical questions, please email info@foundationdb.com."

aquark··on Ask HN: How can one make good money without a career?
There is always a crash coming ...

Are you sure the next crash that knocks N% off the market won't come after the market has risen a further N+x% while your money is on the sidelines?

Are you sure you can time the bottom of the crash well enough to know when to jump back in?

If the answers to those questions are 'yes' then great, otherwise a steady investment strategy for the long haul can just ignore the short term fluctations.

aquark··on Ask HN: Ads provider for charity?
Don't have an answer for the question, but how about coming up with a list of charities you want to support and seeing if they are interested in advertising directly on the site for free?
aquark··on New Tesla battery could power your home, and maybe the electric grid too
Well, depends on location ... I think mine was down around -10F last night and I don't have room for one in a heated space.

I suspect it will be a while longer before battery technology is as useful above the 49th parallel.

aquark··on Show HN: Write (almost) perfect encryption in an hour
Except in some cases you may have a way of securely communicating the key at an earlier point in time.

For example, you generating a 1TB key before leaving on a trip you could imagine a VPN set up that encrypted 1TB of traffic in a way that was theoretically unbreakable by someone sniffing the traffic only.

aquark··on Hands-On with Microsoft's New Holographic Goggles
It looks impressive, but it would help to be able to tell the hype from reality:

"Sensors flood the device with terabytes of data every second" ... somehow I doubt the aggregate bandwidth of the device is > 1TB\s

Makes it harder to know how much of the rest of the 'explanations' are accurate.

aquark··on Show HN: What do you think of my new startup ProductChart.com?
Interesting idea ... might be useful to be able to invert the cost measures. For example on the SSD page seeing $/GB instead of GB/$. Seeing the price per GB go down is more intuitive to me than seeing the GB per $ go up ... not sure why!
aquark··on A 12-Hour Window for a Healthy Weight
I wonder how they managed to keep the calorie intake the same for each group as mentioned in the study?

Either the mice self-regulated this, and the shorter window mice learned to eat more when it was available or there was a fixed amount of food available then the window seems less relevant unless they tracked when the food was gone for the day.

aquark··on Show HN: C#-to-JavaScript compiler powered by Microsoft Roslyn
I find Typescript catches all sorts of typos that get missed in pure JS because I don't have 100% code coverage tests. Sure a JSLinter might catch some of those, but it won't find mis-spelled method names.

Other benefits include not having to remember the 'interesting' rules around 'this' in pure JS (though that occassionally slips through in libraries that use it). Having saner (to my eyes) syntax for modules and encapsulation. And having intellisense support in Visual Studio reduces the effort of writing the code.

aquark··on Ask HN: Is there a service like Stripe but for physical credit cards?
If you want to hook it up to a device with a USB port then there are any number of USB card swipers that will easily reader the card details and you could then integrate with Stripe.

For a mobile solution something like https://cardflight.com/ would be an option which works with a number of backends
