I've never gotten this argument. I mean, I have totally normal (nearly 20/20, but not quite... thanks to aging) vision, yet I can see the blurred edges of diagonal and rounded images perfectly fine on an iphone 5s at 2 feet. I think people just aren't really looking. I tried a thunderbolt display recently, and it was painfully low resolution. I haven't seen the math recently, but I have hard time believing that any phone today, let alone any monitor or television, really reaches the resolution of print.


"after rolling out our optimizations, we saw our error rates (ie. the proportion of slow or timed out queries) drop by up to 400%"

There is some good shared knowledge in the post (unlike this comment, to be fair), but what does drop by 400% mean?

If a rate drops by 100% it becomes zero. I get that.

If it increases by 400%, the outcome is slightly ambiguous (do we add 400% for 500% total or do we multiply up to 400% of the original value).

But a rate decreasing by 400% - am I the only person who finds that (not uncommon) expression hard to conceptualize?


I understood it to mean that it had 1/4 the error rates they were previously seeing.


Huh, that's not even one I considered. I guessed 1/5, so the change was 4x the final value. Either way it's wrong - "dropped by X%" should be calculated as (original - final) / original.


This is exactly right :)


Then it dropped by 75%.


Yes. It was a blunder. The post has been updated to reflect this.


Obviously, he gets -300% errors now.


That's pretty good.


Nice city, but with 114% of the population being smokers...

I love Europe, but for being so developed, it's amazing how many places there people still think smoking is 'cool,' and 'a symbol of freedom.'

I do like Vienna, but I think I'd choose Hamburg if I had to choose a city in the German-speaking world. Or Berlin - only slightly less cosmopolitan, but the tech start-up scene is kind of happening, and the cost of living is cheaper.


Depends on the country: they banned smoking indoors in Italy a while back, and at least in the part of the country I live in, people have always respected that ban (I was a bit surprised). In Austria, when we left, they still let people smoke anywhere and everywhere, pretty much - the only places where it was banned in Innsbruck, where we lived, were McDonalds and Ikea. My wife went out with our baby daughter for cake and coffee with a friend one afternoon, to a pastry shop, and came back reeking of smoke, because some other patrons sat down and started chain smoking. It made my blood boil.

That said, Vienna struck me as a very nice city - very livable for its size, although the climate leaves a lot to be desired.


That's a huge problem in Austria, coming here from Canada I was shocked that you could still smoke everywhere here. I rarely go out to bars or cafes here due to the fact that I then have to change clothes and shower in order to get rid of the smell of smoke.


I agree. I'm Australian, and I'm so used to the very hard line on smoking (e.g. http://en.wikipedia.org/wiki/Cigarette_packets_in_Australia) that the European attitude is really annoying, and I'm very surprised when I openly see ads for cigarettes and even vending machines.

It's probably something I'll never understand, since (to me) it is an obviously bad idea to inhale the carcinogenic burnt residue of some paper and leaves which has well-known, major long-term health impacts as well as compelling you to continue doing so, and to pay for the privilege (not to mention the damage done to others, and the smell all through ones clothes, etc.). Eurgh, the big cigarette companies (and their ad agencies/publicity departments) are some of the scum of the Earth.


Being from Germany I have to agree with the smoking aspect. I'm a non smoker and after spending a few months in the US and returning back home, I was quite surprised how few people in the States smoked and how often you smell cigarettes in Germany. It was very irritating that I didn't have this annoying odor for quite some time in my nose.


it's not that bad. but I find the non-flat giant diamond icon rather ironic. :)


As an ex-Ruby cum Node.js lover recently converted to Go...

Programming in Go, once it clicks, really does feel relaxing and productive. If you're a decent Node.js programmer, it's like stepping up to "Node Pro", in the sense that you work close to the metal with your web server so everything feels clean and easy to wrap your mind around.

But Go code is cleaner and tighter. The code formatting conventions contribute to that greatly, as well as the fact that you just don't have to pull in as much 3rd party code because so much functionality is already beautifully integrated.

There are a lot of positives about Go that reveal themselves over the first couple days of coding in it.

I do wish the documentation convention included not only a brief description each function, etc., but also a brief example.

By the way, I also evaluated Scala for a few days before settling on Go as my preference. I like Scala, but it quickly becomes a sprawling language as your explore it further, and frameworks like Play and Lift bring even more baggage along for the ride. The core language, on its own, was attractive, but overall, the experience just didn't have the compact, robust, completely under control, and nimble feeling that came with Go.

Oh ya, and the Go syntax felt ugly and awkward at first. That feeling quickly faded after a day of use, but it's worth mentioning because I bet it turns some people away from Go before they even get to the great parts.

Just my 3 cents worth.


> I do wish the documentation convention included not only a brief description each function, etc., but also a brief example.

It is getting there. If you run godoc locally with tip, you will find many more examples than there were previously.

See http://golang.org/pkg/path/ for a current example. And the source for those examples can be found here: http://golang.org/src/pkg/path/example_test.go. Note that this technique will work for your own packages as well.

The technology is there, the implementation is still incomplete; but more progress has been made than is easily visible.


The golang website supports other versions; to see the docs for tip go to http://tip.golang.org/


US uses US standard measures, not imperial.


I thought 95% of the syntax was a dramatic improvement over straight obj-c, which I actually don't mind at all.

I admit, the one time I paused was when I saw the trailing return types. It was the only part that felt unintuitive.

By mere convention it felt odd, but I'm willing to explore a break with convention. Seeing how well-designed the other 95% of the syntax is, I'm giving the architect the benefit of the doubt, and hoping that this trailing return syntax ultimately proves MORE intuitive, despite my initial recoil.

I'm really curious now about the practical issues of putting Eero into real-world use (which, since we're talking obj-c here, means OSX or iOS development).


Most of the comments here are way off base, focusing on the relative worth of the objective-c language, rather than the value of Eero for developers who have no choice but to use objective-c, regardless of how good they think it is or isn't.

If you haven't already - I highly recommend following the link. RubyMotion was somewhat interesting, but really didn't feel like a massive improvement over plain old objective-c, especially once you factor in all the Cocoa APIs.

However, Eero looks amazing. The syntax used represents a vast improvement over straight objective-c or RubyMotion. Take a look - it's genuinely exciting.


personally, I've had great luck with namecheap and host all my domains there, then forward to ec2, linode, and rackspace as needed. great means simple and they haven't ever tried to screw me, which is unique among players in that market. i almost never have to think about my domains, and that's what makes a good domain host in my eyes. just my 2 centimes


I'm on the hatin' side actually. Locked down privacy to the max, only to find it all re-opened again when FB changed their privacy options. That happened 3 times.

Those shenanigans finally stopped, but then I'd be browsing the web and find comments like 'Your friend x likes this page.' It's creepy that to see that on a site I've never visited before when I have my FB locked down completely. I understand the technology, but the instinctive reaction is still 'How the hell do you know who my friends are, random website?'

I haven't noticed that lately (desensitized to it?), but I just noticed on a friend's public-facing FB page (I logged out to verify that it was totally public) that it said she was in Country Y, city Z on date D, with ME. There was my full name and my location in the world posted to the world, despite locking down EVERY SINGLE privacy setting available and allowing NO third party applications, etc. Even my friends cannot see or post to my 'wall.' This is all very disturbing, so yes, I'm still hatin', despite recognizing the cool benefits of a single centralized place to stay in touch.


>it said she was in Country Y, city Z on date D, with ME

This has nothing to do with whether or not you have a Facebook account, but rather is based on the behavior of your friends.
