The fact is that you can't transact separate currencies which are on separate protocols, unless you represent one as an issued-asset on the other. Colored Coins use the native currency of its protocol - bitcoin. The developer of the first colored coins client, Stefan Thomas, moved on to become CTO of ripple. Ripple is a new protocol altogether, with advantages over extensions/overlays on the bitcoin protocol, the main ones being no mining and much quicker ledgers.

User-issued assets on ripple have a customizable transit fee which is effectively collected in the issued currency (since the fee is paid from the balance of the issue back to the issuer). For example, bitstamp's issuer fee is 0.2%, so any trades of bitstampBTC or bitstampUSD pay 0.2% of the amount back to bitstamp's issuer address. (the fee is set at creation of the issuing address and can't be changed later).

Even in my day job, I'd happily pay someone $20 who had the experience to clarify some annoying nuance of XYZ framework. Sure, I could keep digging through the API docs for another hour to find it, but they could answer it in 15 seconds. I'm certain I could be similarly helpful to others. Why isn't SO doing this yet?

It's not trying to add anything to the device. It's trying to add a touch interface to websites based on a common (if itself questionable) paradigm. And it's doing it very badly.
And not to mention increased wear and tear on brakes, gearbox and engine due to much more start-stop events during urban journeys especially at peak times i.e. traffic lights, junctions, tailbacks etc.

On top of that, the car will be starting and stopping i.e. engine start/stop cycles far more during urban workload if you're a taxi driver, that also increases the number of times your car will be visiting the shop for maintenance as the life of the car increases.

Cars with high long distance journey motorway miles will last far longer than a car working out its life in a city. This can affect resell value if you own the car rather than lease.

As a fairly experienced second hand car owner/purchaser I'd far rather buy a motor with 100k+ motorway miles than 50k city life on the clock.
I think your missing the point. You are calculating this on the basis that you were buying and using your car exclusively for Lyft. If a driver is already paying for a vehicle, all of these expenses can be shared with personal use. This is the 'sharing economy'.

To buy a car and use it exclusively for Lyft may not make sense.
Ask HN: phpBB or Discourse, which one should I implement?
Hello all. I am finishing the system I am currently working at, and while I need an online bulletin board system, I don't know if I should use the good (?) and old phpBB or the new, fancy (but still "weird" for some users) Discourse.

Profit = marginal revenue - marginal cost. You've counted all vehicle maintenance as a "cost of Lyft driving". For people who already own (and maintain) a car, this is not the case.

Do you have a source for that claim? There is no reason why nodes with different trust lists would become partitioned. Even if a majority of the nodes were malicious, all they could do is prevent the honest nodes from reaching consensus. The honest nodes would effectively stop operating, as every ledger confirmed by the malicious group would be marked as unreliable by the honest group.
How do you think of Reddit in that framework? Reddit itself is explicitly a tool for creating, basically, community sites. How closely does it fit with your vision of a tool for crafting social networks? When do you predict it will fail?
If you were going to approach this in a purely economic-rationalist manner, you'd (probably) discover that buying cars new is wasteful - and that you want to look for late-model full-service-history low-mileage second hand cars in the 2 or 3 year old range. The original owner will have borne the brunt of the capital depreciation, and you can drive higher-than-average-yearly-mileage for a few years while "low mileage" to "slightly high mileage".

(Where I come from, Australia, there are tax breaks that make 3 year old cars fresh off company-car leases pretty commonly available - many people structure their salary package in a way the strongly encourages them to lease a new car every 3 years, and off-load the previous one for often 35% of its original purchase price - and to have those cars get all their required dealer servicing done using pre-tax salary.)
There may very well be better ways. But creating a distributed p2p exchange protocol is probably a lot harder to do than some of the people raising funds and making promises would have you believe.
> There is no shame in being wrong, it is much more important to quickly adapt to new information that has since proved your original assumptions incorrect.

It is also important to create a culture that doesn't punish mistakes excessively. You want smart, creative people taking some measure of risk. If they perceive they will be punished for small mistakes, they'll stop making mistakes (which means start doing only mundane boring things) or will just leave.
This point could have been made more effectively without the typical self-congratatory Millennial bashing.
Uber Cuts Deals to Lower Car Costs
It is a good goal. There are a few lines of thinking about this. One is to stress discipline by coding in the "literate programming" style. Another is to stress writing less code so that less has to be expressed. A third is to make the language representation more suitable for gaining understanding at a glance - this leads to most of the interesting visual languages.

This appears to be benchmark gaming - the POSIX Rationale for fsync(2) says:

The fsync() function is intended to force a physical write of data from the buffer cache, and to assure that after a system crash or other failure that all data up to the time of the fsync() call is recorded on the disk. Since the concepts of "buffer cache", "system crash", "physical write", and "non-volatile storage" are not defined here, the wording has to be more abstract.

Oh give me a break. He's basing his entire analysis on the assumption that it costs $22.80/hr to operate a vehicle. They way he comes up with that is by including the up-front cost of the vehicle.

That's not quite the right logic. Most people do not go out and purchase a vehicle just to become a Lyft drivers. Certainly that's not what you should do.

A better economic analysis is to look at Lyft as a way to make your existing personal car a more productive asset. The car is a sunk cost. What you should analyze is the incremental costs of fuel and wear-and-tear for the additional miles driven vs. the Lyft proceeds.

Econ geek footnote: This is assuming there is little-to-no opportunity cost for being a Lyft driver. But for the unemployed that holds true. Lyft may be a more compelling option for unemployed/underemployed car owners.
Facebook revolves around making people interesting and providing people-based content to consume.

Reddit revolves around people finding interesting content and providing it to others to be consumed with some commentary on the side.

I'm not sure how they're comparable. Sure, reddit has a community aspect, but it's really just a side dish compared to the content (links).
Even if Brent may have overestimated the cost of operating a vehicle, assuming he makes 2X of his projection, that is still less than L.A minimum wage ($8 today. Increasing to $10 by 2016.)
Lyft sends 1099(-K, presumably)s to drivers who make over $20k from 200+ transactions a year. This is the same reporting system used by Stripe and Paypal. (I have lots lying around.)

It would be exceptionally unwise to fail to report income which has been 1099-ed to you, and very unwise to fail to report substantial income merely because one does not have a corresponding 1099 for it, because (particularly in the case where one party has all the information required to reconstruct your income and that one party can simultaneously uncover millions of dollars of under-reporting) audits exist.
This is slightly counterfactual. The Mac today has a solid unix heart and runs on the best processors and technology out there, but that was not always so, and they were weakest precisely when PCs grew strongest.

The internals of pre OS X Mac OS are horrific and disturbing. They are in no way superior to the internals of Windows 95 and are at best only perceived superior due to a different user experience peppered with a healthy dose of self-delusion, certainly not through stability or performance. They are infantile compared to OS/2. Moreover, over the next few years after Windows 95 was released the PC improved greatly while the Mac mostly stagnated. Around the Power Mac era things were roughly even in terms of capabilities and performance though the Mac was significantly more expensive, by the Pentium and especially Pentium II era the PC began to become objectively more powerful than the Mac.

This put Apple into a freefall that they were only rescued from by the return of Steve Jobs who established style as a foundation the company rested on and pushed them into digital media and mobile devices, as well as forcing a hardware architecture migration (to the formerly hated x86 from the PowerPC architecture developed by a consortium of which Apple was a huge part of) and a complete OS rewrite (transforming Mac OS from an antiquated bucket of kludges into NeXTSTEP in Apple clothing).

At the time in question though Apple was pushing old, slow hardware at a price premium in a market that was rapidly passing them by.

I want technology like this in my life. I mean what Google Now ultimately could become. A personal assistant powered by near-magical machine learning. But I don't want to sacrifice my privacy to companies that have proven untrustworthy.

More so than that, I don't want to invest a piece of my life into a service, when Google has a track-record for either A) abandoning the product, or B) mucking it up. Let's talk about the future, where Google Now feels like a human secretary in its capacity for intelligence. One day you ask it to schedule an appointment for a Friday lunch. Instead of the usual friendly acknowledgement, (s)he asks you if you'd like to share this appointment on Google Plus. Suddenly you can't make reservations at a restaurant, without having a Google Plus profile. They wanted to abate abuse of the system by linking reservations to real people. Now you have to "fire" your secretary, and spend weeks training up a new one. And (s)he'll never be as good as the old one.

Hopefully you understand the point I'm making. It wouldn't be so bad, if it weren't for the tendency of all these modern services to form their own little monopolies. Take YouTube for example. I want to switch away from YouTube. But the content creators I love don't have their content available elsewhere. We talk about all the freedom our modern internet enabled society brings ... but yet most of what we create these days gets linked inextricably with some walled garden.

I want a technology like Google Now, but I want the data it learns to be stored in an open format which I can port around as I see fit. I want to be married to my data, not to a service provider.

Having said all that, I know my dream won't come true for quite some time. Non-trivial technology almost always breeds walled gardens, due to the expense required to develop and maintain them. We likely won't see open standards here until the technology is old enough to be implemented well in an open source project.
If you wish to use that analogy, the web borrowed ideas from SGML and project Xanadu and co-opted the best ideas from them, relegating SGML itself and other ideas like it to the dustbin of history.

It is quite possible Bitcoin will be superseded by some other system introduced by one of the existing major transaction processors - they have a huge amount to lose if Bitcoin becomes a standard, and everything to gain by owning the future of transactions.
I'm going to agree with the majority here and say it's probably a bad idea to buy a car just to do Lyft.

However, I wonder if there are any arbitrage opportunities by combining Lyft with something like Flightcar (where you don't own the vehicle).
Ask HN: Feedback on a new messaging app
Hi HN,

I wish to have a genuine feedback on my new messaging app https://itzz.me

Inspired by the idea of twitter @mentions I created a private messaging app. In other words you can send messages just by referencing recipients (@mentioning) within a conversation, its simple and fast way to send one to one or group messages. You can even send email just by giving the recipient's email address in the message.

Very true, there isn't one. But there are several. None of them all that good though. Windows Workflow, System Center Runbooks, Biztalk, they've all made their mark. I've seen serious systems built using all of them, ultimately I have to wonder whether visual programming on that scale is even a good idea.

phpBB has a lot of cruft, both in terms of UI/UX and in terms of the codebase.

But I'm not really a fan of the Discourse style, where once a discussion falls off the front page it's not immediately easy to find again, esp. for novice internet users.

IMHO it's a case of Devil You Know, and Discourse's "benefits" aren't overpowering enough to motivate me to switch in my own side projects.
BoilerPlate Builder - Your own three.js project in 3 min
Nice feedback on my blog post, y'all. Thanks. Estimating exactly how much a driver receives from Lyft, versus that driver's expenses, is really difficult. So I took some shortcuts with easily searchable published data and ended up with just $3.45/hour. In a G+ discussion it came up that if you could externalize most ownership expenses (e.g. driving your dad's car), it would be reasonable to get up to $17/hour with all my other estimates being the same.

In a best-case scenario you'd be picking up someone whose destination is where you were already headed, in which case your 80% of the payment would be pure profit. If you drove that person for a full hour, to a place where you were already headed, and they paid you $43.75, then you really would get that $35/hour that Lyft advertises for drivers.

In the end, these estimates are hard. Lyft themselves probably have real good data on the matter. Maybe they'll give us some real numbers, and show us how they can be cheaper than cabs while simultaneously (if their advertising for drivers is to be believed) paying their drivers a lot more than typical cabbies.

1. In most places it is illegal to provide transport for a fee without a special state-provided license.

2. There are also special legal requirements from the driver, e.g. taxi drivers license.

3. Insurance requirements are different and order of magnitude higher for vehicles that provide such transport.

4. In case of accidents/fatalities or police stops, who bears responsibility/liability? The car owner, the company, the insurer, all of the above? How much danger of arrest/confiscation/huge fines is the driver in? Does lyft indemnify their business partners against such incidents?

5. The drivers earnings should be the least concern for folks who sign up for this scheme

cryptocoin you're hellbanned, no one can see your posts.
Facebook has to evolve from being entertainment, to being technology. For example, look at Steam. It's a platform for distributing games. It's not going away any time soon. They work to improve the platform. They're going to open the platform up, so everyone can publish games. They're not simply a website that tries to sell you games.

Facebook needs to do the same if they want to survive. They need to stop being a social networking site, and be a social networking platform, that others build from. Facebook the site, should be one site of many using that platform. I should be able to develop a social networking site built from the Facebook platform, to compete with the Facebook site. Then when my site gets old, or the Facebook site gets old, new sites emerge, and build off the data from the existing platform. This way, it lives on. However, this will never happen, and Facebook will die.
Clients get to choose the technology not we.

That is why many projects have a ramp up phase for the developers new to the technologies being asked.
Maybe. But the bounty has also gotten the bug a lot of attention (case in point, this HN post).

All it takes is one developer who happens to be an expert in this area to see the bug and say, "I know exactly what is causing this!" and go fix it. What's the saying - "with enough eyes, all bugs are shallow" or something.

I am guessing you have a JS background (i may be wrong. You may be thrice my experience and capability in languages of my choice). Either way, IMO those requirements aren't that weird. When you have VERY VERY huge software, this stuff comes in very handy. I love different, non-OO languages for the magic they bring to the table, but that doesn't mean i'd discredit OO languages.

I agree that some paradigms are more useful then others. Its rare to use declarative and logic based languages. (i assume declrative here means where u declare a goal without regard to how to achieve the goal). But OO is still pretty much needed in a ton of cases. So i wouldn't bunch it into the "less used" category. Heck web development benefits greatly from this stuff too! My current webproject is in JSP! yay java!
