Chargebacks are useful to consumers not because of evil merchants who can steal their money (merchants in general are not evil and care about reputation). The real problem is giving away full access to your credit card. Someone can steal your CC number from any shop you used it before and then make a purchase. Since CC is so fragile, Visa offers you a chargeback capacity putting merchants under huge risk of fraud.

With bitcoin you don't show your whole wallet to anyone. You only make a single transaction to a single address. Merchant cannot possibly leak anything that will give someone ability to spend your money. Instead of spreading your identifying information to 1000s of shops you only keep it in a single place that you control directly (but you should be careful here). So you don't need chargebacks if no one can easily steal your money.

To avoid fraud from merchants, people use "reputation" and escrows. Typically, you will be okay to risk paying 3 bucks almost anyone, but you'd pay 300 dollars only to people you already trust (think Apple Store, WalMart etc.) For very rare cases when you need extra security, go to an intermediate escrow service. (E.g. ebay.)

Thanks. Got a bit recursive there.

Wow. Strong opinions on both sides of the debate.
I guess I'd say most of us try to encapsulate it in directives or use the scopes that are there for us, but even Angular uses JQuery or its own jqLite under the hood.

edit to add:
In fact, on further reflection, Angular passes JQuery or JQLite objects to the Link functions of custom directives, so it's actually kind of opinionated in favor of using JQuery, it just adds some extra layers of abstraction to ease some things.
You can look up real world MPG on a site like fuelly.com. It looks like the first gen Honda Insight is over 55 MPG on average. There aren't enough cars to get a great sample but they list about 75 cars between 2000-2006.
I was wondering why the dates didn't make sense, and why they kept referring to the "Wachowski Brothers" (who are "brothers" no longer).

Well, everyone has their own definition of "elegant syntax" which makes objectivity difficult.

I guess the best tools are ones which help you produce output quickly whilst being conductive to elegance and readability, Ruby's terse syntax and features like blocks are an attempt at this.

It also depends on how big your project will get and how long it will need to be maintained for.

There are plenty of projects I have seen where chunks of extremely bad code have been pumped out to create a 1.0 with a giant list of features. Of course such code becomes increasingly costly to maintain or modify without breaking. In many cases they would have been better off cutting features from the 1.0 (most features are unused anyway) and concentrating on quality.
At zero to sixty in twelve seconds, however, it's not appreciably quicker off the line...well, ok, significantly faster if we use a 1963 Type II.
We use it when talking about heat treating of carbon steel and other materials. Regular heat treat cycles between 900-1050 F. Some reference to higher temps when we talk to the natural gas people.
thanks for the tip. I just checked out their demo page and it looks pretty sweet. I'm mostly still working on applications that have plenty of relational data and server-side data processing, so I don't think Firebase will be of immediate use for me, but I'm definitely impressed. The speed and ease is very nice.

and I'm always forgetting passwords!

These are places to store stuff though, not transaction systems, which is what I was driving at. Bitcoin as a transaction system requires me to place trust in a vendor (or potentially an escrow service). I trust my bank's payment systems and chargeback facility more than either of those things.

Bitcoin as a store of money? Well I still prefer the legal protections afforded me in a regulated bank.

I would consider it an outright bug, if that were the case, so I wouldn’t worry about that.

I haven’t added any photos to my favourites, so I can’t test it for you, alas.

@YahooCare are very quick to reach out, if you direct any questions at them, as shown in the last of my footnotes. It’s actually really weird, albeit a pleasant surprise, to see a big company respond and reach out to users in 2013. :)
Sure... But then 20 minutes for a 100 miles even with not much things to do is good to me!

The problem is less likely the distance but availability of charging stations.
Honestly I don't mind that. On a longer trip, now that I have a family we wind up spending that long walking around, stretching, bathroom, etc. So the problem isn't really the wait; it's the fact you'd have to do it every 60-70 miles. But, considering a typical day trip is within 150 miles away, it might add an extra hour or so to your total day. Still not feasible to go cross-country yet, but I think we're getting there.

Not always. Sometimes they bring out some inner beauty in the code that was previously hidden. But, again, sometimes they don't.

It depends on your priorities. If you were a poet, would you be more worried about making good poetry or selling more books?

Again, it depends on what is your output and how you relate with the fact that the thing generating that output is a horrible mess.

The few places I have found which more or less matched my points seemed to be rather profitable and I know have been around for a while. I've tried co-working spaces and didn't particularly like them. I know it's really subjective but most of them felt pretty sterile (like so many open-space offices). I find I'm more productive in a (good) coffee shop, but that's of course pure personal preference.
thats great. thanks. I'm still learning about Angular and had been using $http pretty much raw for most of the data fetching. I started to play around with $resource but didn't get very far due to some frustratingly vague documentation on the official site.

Very nice but it will never gain any sort of mainstream penetration unless EVs get to at least 200 mile range or perhaps charging technology that gives you 100 miles with at most 10 minute charge.

There are very few folks that can say they only drive 100 miles at any one time.

That's why my next car is going to a Prius Plug in (if they EVER get them in all 50 states - sheesh!). This gives me the all EV range for work (15 miles round trip) as well as the extended range for longer trips.

Fun fact: mod_php can't safely coexist with anything else.

A few years ago, I briefly ran a webserver that had both mod_python and mod_php installed at the same time. Everything seemed fine until I tried using md5 from Python and repeatedly got completely wrong values:

>>> md5.md5("hello").hexdigest()
'00000000000000005039985304054aac'
>>> md5.md5("hello").hexdigest()
'00000000000000009ebb1c1ea77b5505'

As it turns out, both PHP and Python defined MD5Init, MD5Update, and MD5Final functions, with slightly different interfaces, and ld.so picked a winner to be shared by both of them.

But I get your point about PHP's deployment story being one of its (arguably few) strong points.

Show HN: keyboard shortcuts for rapid css prototyping
Umm, no. I exactly want protection from unscrupulous merchants. Stolen CC detail fraud is on the decline thanks to the likes of EMV cards, and I also have legal protection from it via my bank for when that fails.

Reputation and escrows are really no equivalent to legal protection from merchant fraud and instant refunds on dispute. We have centuries of history with shysters and scammers (CAVEAT EMPTOR) to show us why this stuff is useful and it's pretty trivial to fake reputation and to fake escrow.

Nicely cementing the big boys in the market and locking out smaller vendors forever.

I'm sorry people feel so affronted by consumer protections and chargeback, but without them I wouldn't buy stuff off the net at all.
DJ Falcon live sets. You have to pirate them, since they are just recordings of him doing live shows and are not available commercially.

DJ Falcon is part of the French House genre. He has done a few records, but is known primarily for his live DJ shows and his collaborations with Thomas Bangalter of Daft Punk (Together and So Much Love To Give).

If you like Daft Punk, especially if you like their Alive 2007 live album, you'll probably like DJ Falcon's live sets. They're rhythmic, melodic, and interesting. There are frequently parts of 3 songs going at one time, which sounds like a recipe for disaster, but turns out utterly sublime.
What kind of example does this set? Now we're encouraging more kids to blow stuff up at school, great! </sarcasm>
Ooooh, I have been looking for precisely a book on that topic. Thanks!
I've been hoping to some day find a car that is a worthy replacement for my Honda Insight. The Volkswagen seems to be similar in many ways: comparable horsepower, weight, covered rear wheels, etc. I doubt it'll be $22,000 though.

A friend even was able to get similar mpg numbers by boosting the battery pack to a similar capacity (in a competition). Too bad the market didn't shine on the early Insight. If I remember correctly, they only sold 20,000 worldwide over its 8 year run.
>the XL1 can putter along for 32 miles and at up to 62 mph on electric power alone

I wonder what kind of numbers they could get out of an electric-only version. 62mph is near the legal limit of highway speed anywhere I've ever been, so for me that would be a fine limitation. If they removed the diesel engine, the extra drive-train components it requires, and the gas tank, they could save more weight. With just that weight savings, the range would be improved. It also leaves room for installing a larger battery. 32 mi on a 5.5 kWh battery is nice, but of course the public wants more. For reference, the Tesla S with the largest battery option (85 kWh), can do 265 mi.

It is good to see a car company pursuing a radical design.
An AppSec Speed Bump On The Road To The Future
Of course you can, but most of the time you don't want /blog/index.php?slug=title-of-the-article, you want /blog/title-of-the-article. To do this in a CGI-style app (i.e. mod_whatever) you've got to mangle the URL in the webserver layer. This moves application logic out of the application and into a config file for some other program, so it would be bad even if Apache's rewrite syntax wasn't incomprehensible black magic.

It cuts both ways, too. CGI-style routing gives a URL to everything, whether you want to or not. Unless you explicitly disable it, visiting /blog/config/database_credentials.ini (or whatever) will happily serve that file to the client. Plus it allows any user to execute the code in any file in your system out of context. Admittedly this will probably either error out or do nothing, but can you guarantee that for every single code file in your whole tree?

There's two kinds of innovation around technology platforms: you can innovate with the platform itself, by designing new operating systems, programming languages, browsers, libraries etc. Or you can innovate on top of the platform, by doing new things a level up. We benefit most from a balance of the two.

Mozilla aren't resisting innovation. They've chosen to keep Javascript (the platform) and innovate on top of it, e.g. with pdf.js. Google is aiming to develop alternative platforms. They're both valuable activities.
Personally, this would be a perfect car for my daily commute.

Modern diesels have tons of "technology." When you're running pressures above 40,000 PSI on the common-rail and doing direct injection, there's quite a lot of tech in a modern diesel engine. Older, dirtier, diesels don't need this tech but emit quite a lot more particulates and other unwelcomed emissions.

Any of the urea injection technologies are a pain. Some modern diesels have low enough emissions to not need the urea. We need more of those and less urea.
IMO that rule was made to prevent the cars from going through slow corners too fast, The speed restriction only applies to cars that have the motors connected to the front wheels. The Toyota cars have their hybrid motors attached to the rear and they can use their hybrid system from 0 kmph.

Mk1 Golf GTI was very light: 790kg, as was the Mk2 Golf GTI 910kg (hot hatches from Europe) but ever since then cars seem to be minimum 1,200kg. They are a lot safer and that is the main reason. You can walk away from a minor crash with your legs intact.

Car manufacturers have been upping power (speed) over the years and this has lead to an increase in weight from a performance and reliabilty standpoint but also safety.
