I'd make a 100% bet. These services try to muddy the waters though from what would otherwise be clear cut.

Lyft for example brands themselves as a "friends giving friends" rides type of arrangement and they call the money exchanged a "donation" so they tell drivers, "who is your insurance company to say you can't do that"!

Uber acts like personal insurance will cover it as well if you are an UberX driver but then in the fine print it says it is the drivers responsibility to confirm driving for a "P2P" ride service is ok with their insurance company. Of course if you call any of the major insurance carriers and ask them they will tell you, "hell no that isn't covered".

If you look at the taxi insurance market it is made up of a bunch of dinky little companies no one has ever heard of or in some cases taxi's are insured by quasi government insurers of last resort or by verifying you have the minimum insurance requirement on hand in cash. None of these options is cheap so it isn't surprising that ride sharing services would want to avoid them because they would have to end up paying the drivers a lot more and they would no longer be 30% cheaper than taxi's

I think the way we try and explain physics with analogies and simplifications is often more confusing than just showing the equations.

Pre-Einstein we assumed "Galilean relativity" almost by default: the idea that if you're moving at a constant velocity, the results of any experiment you can perform are the same as if you were standing still.

Maxwell's electrodynamics is a wonderful, beautiful thing and well worth learning, but the relevant part here is that it implies that light always propagates at a fixed speed. And we can perform experiments that verify this, and we can - more or less - perform those experiments while moving at speed (or we can find clever ways to test the theory using the motion of the Earth, as with Michaelson-Morely), and we observe that they still hold.

So then just think about objects moving at constant velocities, and how to reconcile their observations with each other - for simplicity, you probably want to start with 1D space. Plug the observations in, write some numbers, and special relativity more-or-less drops out as the only way things could possibly work. It really is a lot less confusing than it sounds.
well of course its easy to fire up sentiments against some one who is "different" rather than dealing with the substantive issue.

Trademark registration has an examination process where an expert looks at the details of the application and judges as to whether it meets the statutory requirements. It's just different nomenclature.

This http://lawoffashion.com/blog/story/11/16/2012/164 is an interview with an ex-USPTO trademark examiner turned trademark attorney.

That's not to say that every application for registration is treated with rigour and care just that there is absolutely an examination procedure. In the UK one of the targets is [was] a high degree of validity, ie if courts overturn the registration then you've failed.

To be fair, the video game industry has brought this upon themselves. They haven't innovated much since the SNES era. 90% of the profits went to Call of Duty and Madden sequels for a long time.

King and their ilk aren't cutting into that, they're innovating games for people who previously didn't play them. It's a positive thing.

This seems to be a design flaw, not an implementation flaw.

Summary: Ethereum's proof-of-work function(called Dagger) is designed to be memory-hard, but someone pointed out that it should be designed to be sequentially-memory-hard instead. Dagger is not, so you can parallelize the computation.
Thanks. That actually answered my main question: how did they manage to remove the big scary red wire. It shows how to use a discharge tool connected to ground to discharge the anode wire. Even before doing such a thing, I'd do some more research on servicing CRTs before attempting such a thing.
If I may, one additional thing that I found which helps a lot with memory issues as relate to MySQL: Use jemalloc or similar. Essentially I brought a system which killed off the MySQL service every few weeks in OOM, to running faster than ever and never having memory issues.

That isn't to say it's a substitute for full troubleshooting, but as a first step, using a different malloc routine can sometimes help quite a bit!
It’s possible that I’m simply blind to the complexity of these tasks because I regularly do exactly these operations in C (dropping into assembly for performance reasons). If you do something often enough, it does start to seem straightforward. That said, there’s 30+ years worth of software written by other people in C that performs similar tasks. Much of it is horrible and ugly, but there are gems that are exceptionally clear and beautiful (more so than what I’ve seen in almost any other “mainstream” language).
The only one I know of that fits this criteria is Primecoin, its proof of work function is to mine prime numbers.

I haven't heard of any others, but I'd be curious to know about them.

why Gett can't sue Uber in this case ?
Ditto - very odd given that it's both a huge usability improvement and something Apple already had developed. A little time porting the services menu from OS X to a touch equivalent and it'd be done, probably without even needing an API change.
I feel insecure about being a non-technical founder
Hi,

I was just wondering, as someone who is currently in the process of outsourcing development for an app idea of mine, if I am right to feel insecure. I mean, I try learning the basics of objective C, so I can understand what is going on within my own app, to a degree, but I feel like if I never really know, I can never be successful in the app industry... Am I right to feel this way?

http://wiki.ethereum.org/index.php/Dagger#Algorithm_specific...:

You sound knowledgeable, so perhaps you could clean up their algorithm for me? There are a number of problems with their description that make it hard for me to evaluate. Having tried designing a memory-hard algorithm, I'd like to see what their key insight was, but there are a number of problems with their article. They use confusing operators, the wrong terms, and seemingly random constants.

How did they come up with the numbers 2, 3, 11, 2^21, and 2^22, for example? Is D the hash function or the underlying data? Or is 'data' the underlying data? Does + mean addition or string concatenation? What about "++"? They never even use "||", which they defined as string concatenation... Where does the nonce N come in? Is that actually supposed to be 'n'? How do they justify that the optimal algorithm is the naive one? There is essentially no proof of this claim in the article.

In short, I'm very suspicious of their "memory-hard" algorithm. It took a fairly dense, multi-page whitepaper to explain Scrypt, and yet their 'superior' version is just a couple of sloppy lines of pseudocode with no justification.

Here is what they wrote, for reference:

Let D be the underlying data (eg. in Bitcoin's case the block header), N be the nonce and || be the string concatenation operator (ie. 'foo' || 'bar' == 'foobar') . The entire code for the algorithm is as follows:

0: D(data,xn,0) = sha3(data)

1: D(data,xn,n) =

2: with v = sha3(data + xn + n)

3: L = 2 if n < 2^21 else 11 if n < 2^22 else 3

4: a[k] = floor(v/n^k) mod n for 0 <= k < 2

5: a[k] = floor(v/n^k) mod 2^22 for 2 <= k < L

6: sha3(v ++ D(data,xn,a[0]) ++ D(data,xn,a[1]) ++ ... ++ D(data,xn,a[L-1]))

If it's a command we start to use often we bind it to a shortcut (If I may presume to speak for emacs users). It's not much different than shell commands. Some you just type, some you create an alias/function shortcut for.

I recently discovered an emacs package that lets me type M-x and then the first letter or two of a command that I used recently and it completes it for me from there (smex.el). That's even easier than coming up with a new keybinding.

Just to try and help you understand how emacs users see it, your most common vim commands that are a single character are actually sometimes a single character and sometimes they need to be prefixed by an ESC to get you into the right mode. That inconsistency is what killed me when I tried to use vim. In emacs every command is always the same, no need to keep track of what mode I'm in.
That's just blindness, though. They only see the rising rents, not that they can't afford the rents anymore because they don't have tech jobs. It's just different sides of the same coin.

I'm sure it's not a popular opinion, but when Uber itself is a business that seems to exist on the border of legality, this type of stuff isn't that much of a surprise to me. Uber et al. specifically skirt around regulations that cab companies have to abide by, which, at least in my opinion, sets the tone at the top that legality and ethics are somewhat secondary to the mission of the company.

IMPORTANT: I've used Uber, and the experience has been great. All I'm saying is that I don't love the cavalier attitude towards city regulations on taxis, and that I think that attitude flows down the chain.
Probably because people think programming is using Codewarrior and Applebugs. I used Hypercard and Excel but never considered it programming until I got to college and did most of my calculus work in Excel (Matlab was too much work to setup).

My first attempt at "programming" on a Mac ended up being pretty disappointing. Codewarrior required a FPU and the Performas had the 68LC040 instead of the proper 68040. All those C books I checked out from the library were wasted until I could use the school PC lab, for the 30 minutes of free time I had.
Plus, your DNS provider doesn't have a business incentive to prevent you from bootstrapping other systems off DNS. So it happily could put eg per host IPSEC keys, or SSH host keys in strongly authenticated DNS records.

Why do you say that lxc (and cgroups) are less powerful than FreeBSD jails?

From what I read in https://wiki.freebsd.org/Jails, jails don't yet have support for:

* separate PID space
* IO isolation

cgroups provide extremely fine grained isolation, including among other things:

* per-container OOM handler (userspace)
* per-container swap
* per-container disk I/O scheduling
* per-container memory reclaim
* per-container dirty page (write throttling) limit.

These are very important features if you want to increase your utilization by mixing workload on shared machines.

Thanks for suggesting to watch "I Am Cuba", I definitely will.

"The Cranes Are Flying" is an amazing movie, I totally agree. I think it is a great illustration of an idea that morally-strong and courageous people are the first ones to die in hard times.

If you like "The Ascent", I wonder if you'd also be fond of her other movies, first of all, "Ty i ya" (1971) [1] (The film has it's fair share of problems but I find the main idea behind it really powerful). I'd also recommend you to watch movies made by her husband, Elem Klimov, at least, "Come and See" [2] and "Rasputin" [3].

As about "Come and See", for me it has a somewhat personal theme: when Nazis were exterminating the people of his village near Ula, the grandfather of my ex has survived only by chance. His mother, while holding him, has jumped into the ravine before the bullets hit them.

The analogy was perfectly good. Everyone knew what he meant. He wasn't saying that the statistics of trucks vs cars will apply to PCs vs Other devices.
Lots of bantering about whether or not it's ethical / low. tl;dr: It probably is; Travis probably doesn't care.

Honestly, since all that really matters to Uber is $$ and being forced to deal with the law (and even then only barely), Gett should just sue them. It's clearly illegal (putting aside differences between NY/CA law) and it proves the point in a way they'll be forced to notice.
Don't listen all the whining. When I moved to San Francisco in 2008 to work on a startup, I rented a small bedroom in a house with an immigrant couple for $450 per month. If you want to make it work, you'll make it work.

The Amiga OS was very advanced in some ways, but extremely primitive in others. It was basically a hyper-advanced games console with a keyboard. The UI was minimally functional, limited to non-existent support for printers or peripherals, etc. It just wasn't intended to be used as anything other than a games machine and provided none of the features a business machine would need. I speak as a very proud owner of an Amiga 500 since 1989.

Clearly King.com don't end up looking like the good guys here - although as the article does freely admit, "Scamperghost isn't the most original game in the world. It's obviously inspired by Pac-Man" ...

Which rather does bring to mind the supposed conversation between Bill Gates and Steve Jobs, where Jobs suggests that Windows has copied the Macintosh, but Gates responds that "I think it's more like we both had this rich neighbour named Xerox..."

No kudos to king.com either way. In cases like these I'm almost inclined to wish that someone would just come up with a really really good "inspired by..." game and release it for free just for the hell of it. (Not terribly good business, admittedly, but you have to admit it would be pretty satisfying. I don't see a "Sugar Crash" in the app store yet...) :)

Many thanks. I must stick with my interpretation, as the association is now indelible as it is accurate.
>You can still buy a sub-$2000 mining rig that will basically pay for itself in a couple month

No you absolutely can't. About 6 or 8 or so weeks ago I was making about $4 a day mining scrypt coins. Now I'm making $1.50. I don't think it is going to be profitable 6 weeks from now. When Dogecoin first exploded I had several $15-$24 days. Right after I first started there was actually a graphics card shortage(!) because of the interest in mining.

My graphics cards haven't been paid off yet with just mining, and I don't think they will be. That's not a problem for me, because I can sell one of them, and keep the other, which will pay them off.

If you don't already have the PSU, CPU, MOBO, etc, you are wasting your money building a mining rig, especially now the profits are so low. Only buy a graphics card if you want the card for other reasons. Those mining profit calculators way way way overestimate.

EDIT: My system has 600 kH/s hashrate.

EDIT EDIT: Even 6 or 8 or so some people on the litecoin mining subreddit were very confused about people who were building expensive mining rigs and pointing out how those rigs will never pay for themselves.
I agree, but it is rarely the fault of the person presenting them. Unfortunately most "easy to use" graphing technologies (with Excel being the worst offender) take the most deceptive graphing techniques and make them defaults.
Which is also not true. I never payed for OS X, like as a line item on an invoice. I do cover the cost of manufacturing, as with _every other good sold for profit_ out there.

I do cover the cost of the software on the hardware, but the same is true for about any device I buy.

The thing is: Microsoft is trading software as a good. Even if I buy a machine with Windows, I can actually, in some legislations, ask for my license money back and my machine gets cheaper. So I didn't get Windows "for free". So their market is software and should be counted as such.

Apple sells hardware as a good and doesn't ask for any fee for the software that comes with it. So that element is free. Even if I would ask for my money back, the answer would be "sure, here's your 0 Dollar".

Yes, it is an accounting question, especially because in the Microsoft case, your vendor pays the fee for you immediately.

You cannot buy an OS X license anywhere anymore.
> 25 men. 3 women. 2 machines.

Not that it's significantly better, but there are 5 women, not 3: April Greiman, Jane Metcalfe, Noemi Trainor, Es Devlin, and Dr. Pardis Sabeti. However, they did choose Rosetto instead of Metcalfe for 1997's main photo, so there's a case to be made for 4 (though Metcalfe is in the photos when you scroll down).
That sounds more like mathematics.

You read too much into things:

> The original ancestor of this thread was put off Owncloud by the fact it was PHP and Pydia was offered as an alternative.

No, I said I preferred Pydio over ownCloud. You added the subtext to my post.

> The name suggest at least to me that it would be Python based.

Only if you place too much emphasis on naming conventions. Names are in fact just arbitrary labels, thus not everything that begins with "py" has to be written in Python.

> Now whether the PHP should put us off is a separate question. I have probably unfair doubts about the quality of things developed in PHP based worrying about the sort of people who would choose it when they have a free choice (see fractal of bad design post).

I'm aware of the Fractal Of Bad Design blog post and you're using that to justify your conclusion that 2+2=5. Just because a language might be -in our opinion- complete garbage to develop in, it doesn't mean all code developed in that language is garbage. And you're also making the assumption that all developers choose PHP because it's easy; where as many of these projects are actually written in PHP because it makes it easier for end users to deploy.

> C or C+++ so that the barrier to me tinkering/fixing is lower.

If you think writing a web application in C or C++ (two pluses) lowers the barrier of things that can go wrong or the amount of tinkering you'd need to do, then you clearly don't know what you're talking about. Sorry, but that last part just struck me as the stupidest thing I've read in a long time.
This is a feature! You can see from the domain name who you're trusting. Wouldn't it be great if TLS let you know in a similarly obvious manner when your CA is the USG?
My biggest gripe is that the game is designed in a way to extract as much money as possible to the detriment of the game itself.

There are several levels you'll play where you have absolutely zero chance of winning (particularly the later levels where you need X of this and Y of that) because the colors just don't come up. Yeah, that's down to randomness, but it's one of those things that could be resolved. Also, when playing if you receive a call or switch to some other app in the middle of a game you lose your game and that life. Yet another way to pluck more money out of people. Then you have the arbitrary play limits (3 days to unlock another pack via bonus levels, 30 minute waits for lives, etc).

I'd have much less of a problem with the game if each level had a solvable method to it. Then you can make it pay to pass or skill to win.
