> What is the required dropout spacing to fit the Copenhagen Wheel?

> For a single-speed, you need a 120mm dropout spacing and for a multi-speed a 135mm dropout is required. If you are unsure about your dropout spacing, please contact us and we will help you determine if the Wheel will work with your bike.

> Can the Copenhagen Wheel be used with a multi-speed bike?

> Yes, the Copenhagen Wheel is fully compatible with multi-speed bikes. You will be able to use it with 7 speed, 8 speed, 9 speed, and 10 speed cassettes. If your current wheel is a free-wheel (not cassette), then you may require minor derailleur adjustment.

"We're going to need verifiable sources for claims like that."

This entire parent+thread argument back and forth is completely absurd.

It doesn't matter whether he has sources. It doesn't matter whether that firm does or does not exist. It doesn't matter what you think of their tech or his explanation or who is who or what is what.

Your phone has two[1] completely independent, full-featured computers inside of it, totally distinct from the actual computer that is your phone (that you use) that are completely out of your control, and depending on the model, have up to DMA control over your device.

Whisper systems does not solve this. SecurePhoneBlahBlah does not solve this. Moxie Marlinspike does not solve this. If you have a smartphone, you are owned at a deeper level than you've ever been owned before and there is nothing you can do about it other than removing your SIM card. Game over.

The normal way is that initially, when the taxi commission is formed the agency sells them, and then after that the medallions are in private hands, and are a resell-able asset of the company that owns them.

Slightly unrelated, but at least in the US "Organic" does in fact have a specific meaning with real standards that require USDA certification before a product can claim the term [1]. You may be thinking about "All Natural", which is effectively meaningless [2].

Markov chains work well for artificial language and name generations. One of my first programs in 1979, when I was a 13yr old kid, was to sum up the occurrence of characters following other characters in text files, and to roll dice on this table to generate names for role playing games.

I later learned that I reinvented Markov this way. I still have those printouts, and use them when ever I need a name for a role playing game NPC.
Good inspiring article.

I recently added 3 rules to my life.

1.) No pop
2.) Track calorie intake via loseit
3.) Exercise everyday (even if it's just a 10 minute walk or some pushups)

Two weeks in and I feel way better. I find that I'm trying to control my calorie intake and get it where it needs to be without exerting as much effort as I would be if I was simply counting calories to lose weight. I find that I'm doing more than the minimum in terms of exercise too just because I'm already doing some exercise.

At least I found having rules helped me not push off weight loss until next week forever.

Also, if you go to the Strong Towns[1] website that Charles Marohn helped start and read the Mission Statement and their Quantification of a Strong Town, nowhere does it talk about population density or converting suburbs/towns into cities.

You mean like these?

He absolutely is talking about density. The tax bases of low density suburbs, compared to the maintenance costs that they require, are inherently disparate.

The costs of building greenfield infrastructure is low...low enough that developers willingly pay the infrastructure development fees in exchange for the right to build. But the taxes used to maintain the infrastructure do not cover the costs, and by that time the developer is off the hook. So they bring in new developers, which bring with them new taxes and more deferred maintenance, which brings solvency in the short term and bigger problems in the long term. Suburban-density development is a ponzi scheme, inherently unsustainable, and it is a theme that he refers to extensively in his writing.
Hi, I don't think many of the criticisms that apparently been up voted are quite fair. Criticizing someone for being new. It's pretty stupid. Criticizing a new firm for not being well known.. Merrill lynch went bankrupt. Bear stearns went bankrupt. The whole industry is gambling what is this need a proven reputation bs..

I do have an important trading question. what are the fees I will pay as a trader using your service?
Usually, you'd have a row and column per word in your dictionary. Rows would represent the current word, and the columns would represent the next word in the sentence, with the transition probability of each cell in the matrix being determined by counting the frequency of occurence of each word pair in some body of text.
When I was a kid, I tried this with imported Zelda/Final Fantasy games. As an American, I was lucky enough to study Japanese as an elementary schooler, and back then, there was a pretty significant lag between Japanese and American releases.

Consequently, I had some pretty massive incentives to try out these RPGs and muddle through the language (play the game months before my friends!). Unfortuantely most of the kanji was beyond my ability to divine, and I didn't know how to use a kanji dictionary effectively back then...so I often didn't really know what I was doing, and wound up getting the English versions too.

Still, if I had a bit more support (slash knew how to use a kanji dictionary), I could have imagined it really working to improve my Japanese ability. Now that the lag doesn't exist for game releases there's not as much incentive, but it would be interesting to see someone design a game with these sorts of things in mind.

Just in case anyone else is wondering, this is indeed the same wheel that Andy promoted throughout season 7 of Showtime's "Weeds". I had no idea it was a real thing, so I assumed this was a joke at first.
Bingo, thought it made a nice contrast with "Ecotopia."

You are not entitled to require my HTTP agent to request assets I do not desire. I GET your HTML and I request the additional files I want. I override your CSS with user stylesheets if I'm colorblind or I just like seeing ponies in the background. I write my own custom JS to run with your page if I want.

I'm pretty sure my ability to touch type was influenced by playing Quake 1 and Quake 2. You had to type quickly enough to insult someone and not die.

I've met programmers that don't touch type, but I've never met a PC gamer that doesn't.

And yes, your idea would be awesome. That would actually be a sick WoW add-on. I doubt you can pull different localizations through the API though.
> how about new paradigm - context-oriented programming :) where, like "this/self" in OOP, ctx is always present.

This is how OOP in C is done though usually its done with the context being an opaque object.

Having functions with multiple arguments that depends on other functions with multiple arguments that depends on yet other functions with multiple arguments will result is very hard to manage function dependencies sooner or later and "context-oriented-programming" solves this problem very nicely.

A function that takes a single argument as a pointer to a struct can be extended indefinitely without breaking the function API.A function that takes its arguments by individual arguments will break everytime it need to be extended by an additional argument.
Might also be country dependent. I'm using amazon.de (besides .com for prime instant) and Germany is known for it's strong consumer protection laws so Amazon might have beefed up their service here. But I've read some articles before from US customers having amazing experiences.

Some businesses are already planning to use the feature.
There's actually been quite a few VC backed companies try this model: App.net and App.io come to mind. The beautiful thing about Appsites is that we won't be taking money -- from anyone. So we don't have the same pressure to be a $100M to business. We're perfectly content being a $100k a year business. We're completely bootstrapped and intend to stay that way. So as long as we're pulling a profit, we intend to keep our customer's websites running.
Thanks. Will check it out. Do you mind if I post a review to my coursemania site?
I'm not sure MGP resellers control the mash bill; rather, MGP sells a variety of different whiskeys, so they presumably get to pick from a menu.

The aging process however makes a huge difference; it accounts for probably most of the flavor of the whiskey. So there's definitely potential for bottlers to add value. Unfortunately, most of them probably don't, because the things that add value --- sourcing quality large barrels instead of small casks, aging carefully for a long time --- add cost and delay time to market.
"I've heard the best recommendation is a tablet + USB LTE dongle, to put some space between the two processors "

This is an interesting, and tempting, direction to go in ... my understanding is that this is problematic, however.

You see, in addition to all of the (radio stuff) that the baseband processor handles, it turns out that they also handle a lot of voice quality functions, such as noise cancel, echo cancel, interference, etc. - all things that we take for granted on all phones.

I have been told that VOIP apps running on non-mobile-phone "handsets" (like you're suggesting) are somewhat difficult to use for plain old voice, because they lack all of these functions which are difficult to replicate (and are wrapped up in a lot of patents and trade secrets, etc.)

I have no first-hand experience, however.

The other thing that AWS has going for it is widely adopted third party support. Pretty much any software, site, tool or service that has any sort of cloud monitoring, deployment etc feature will be integrated with AWS. This not true for any of AWS's competitors. I've never seen a third-party provide support for an AWS competitor before supporting AWS. I know monitoring tools that do not support Azure, Google Cloud or Rackspace. I know libraries that don't support all of them but always support AWS.

In addition most sysadmins and developers will be more likely familiar with AWS's tools, API and dashboard. They'll be more likely to already have their development environment set up with AWS command lines tools. You ever heard of someone with HP cloud tools installed [1]? I frequently browse dotfiles on GitHub and often see non-sensitive AWS credentials and aliases. I've never seen a Rackspace or Google Cloud thing in them.

AWS wins on mindshare. It's also a proven system. Infrasture decisions are really important, and downtime is very bad and when you choose AWS you know at the very least that if your shit goes down because of provider issues everyone else will be down too and you can kind of get a pass (although outsourcing downtime is kind of shitty), but if you're not on AWS and your shit goes down because of the provider people will ask you why aren't you using AWS. Your customers and investors might actually be unhappy with you because of this.

As for support Google also has terrible support, Rackspace's managed support is very expensive and actually probably not what a competent team would want, otherwise it is easy to get a person on the phone at Rackspace, so that is commendable. Support doesn't scale, but if you are paying AWS a lot I bet you can get support.

I don't really like the mono-culture of AWS everywhere, but I feel like the points above need to be raised. A standard on APIs like OpenStack would be nice, but implementations will differ and AWS will fight this kind of change and because of their dominance getting traction will be hard.

I don't think that fact that you're only looking at lossless compression is clear enough in the post. People see "JPEG" and "compression" and they assume you're talking about lossy compression. The post doesn't include the word "lossless" to describe what you're doing, people have to figure it out.

I agree - I downloaded and played for at least a couple weeks. Important note: I'm not a gamer and rarely ever get caught up in a game for that amount of time.
MAC addresses are bitstrings typically written in hex and should not be interpreted in a case-sensitive manner. You should also accept colons, dashes, or nothing as the byte separator.
Yeah. You can get managed hardware (for example at Soft Layer) for a much better price/performance ratio than EC2. The upfront costs are higher but the price for equivalent hardware is way cheaper.

I think EC2 makes total sense for variable load (I paid like $0.25 to run some Coursera homework on a huge computer for 15 minutes and that was amazing) but if you're running something that needs to be up constantly and reliably (e.g., a database) EC2 gets expensive pretty fast.
Hacking Facebook’s Legacy API, Part 2: Stealing User Sessions
5-10 minutes. It's an easy walk. Maybe...2 or 3 long blocks in NYC.

I realize of course that I got "lucky" and live in a really especially great suburb. However, I've noticed most of the developments in my area tend to be similar. A central "town center/shopping mall" surrounded by condos and apartments, surrounded by townhouses, surrounded by single family homes.
It seems reasonable to me. Good documentation is a critical part of a project's success. It's hard and valuable work.

And think of it in terms of replacement cost. What would it take for all of these changes to be made by core developers instaed? Every moment we have the core developers working on the crypto while a supportive community takes part in documentation -- at a rate far, far lower per hour rate than I imagine the core developers would value their time if they were contractors -- is a net win, in my figuring.
I went the exact opposite route. After losing 180 pounds via bariatric surgery and then regaining 70 of it, I dove into the science. I read books, but only books that pointed directly to scientific literature I could read. More importantly, I learned how to differentiate good nutrition studies from bad nutrition studies (hint: at least 90% of nutrition studies are bad) so I could tell when an conclusion is warranted by the data versus when it isn't. I also started completely ignoring anything said in the media, since, invariably, they get it wrong or they hype the afore-mentioned bad studies. Everything became about the science and the n=1 experiments.

What I found was that I could lose weight without effort, improve every health marker, and enjoy the foods my body really seemed to desire (as opposed to foods engineered to cause cravings). The 70 pounds disappeared without any tracking of anything[1]. More importantly, that 70 pounds was gone a year ago, and maintaining the loss has been just as straightforward.

I applaud anybody who finds the method that works for them. It's pretty clear our bodies are striving to be healthy and get what they need; once you find that, the rest comes relatively easy.[2]

1. There was some early tracking as I learned about different foods and how they interacted with me and my goals.

2. Unfortunately, some people lost the genetic lottery (less than you might think) or are so metabolically disturbed (becoming more and more) that it isn't always easy. I have a huge amount of respect for those who persevere through that and work towards a healthier life.
I haven't played an MMO in a long time, but when I played Final Fantasy XI, a large majority of the players were Japanese. The developers included an auto-translate function so you could have something like "Let's go kill [boss name]" and [boss name] would be translated to either English or Japanese depending on the player settings. Once you got familiar with the game and what you did in it, seeing just [stuff] in the brackets got you the gist of what they were saying.

Unless you were trying to learn Japanese though, that's as far as you got -- you couldn't have the seamless "mata a 12 [green dragons]" unless you knew your hiragana/katakana.
I've had an intuitive sense for a long time that the innovation rate has fallen dramatically since the 1950s. What we're doing now really feels like small incremental improvements to technology that was all invented prior to 1970.

Has anything actually been invented since 1970?
