Hmm, I get the following:

I suspect this has something to do with my terminal settings, but I'm not sure quite what...

Nifty idea, regardless.

The script is not a proper POSIX bourne shell script, as it uses arrays.

For starters, it won't work in dash (Debian and Ubuntu /bin/sh implementation). So the shebang line should be changed to #!/bin/bash (not sure if it would work in Zsh either).

"At the time, the only way to donate marrow was to basically have someone drill holes in your bones and drain your skeleton, which kind of terrified me. Nowadays, of course, most donations require nothing more than sitting still for a few hours with an IV watching television."

That actually isn't really true. Marrow donations still require anesthesia and a surgical procedure. In the interest of providing full information:

To the extent it's still relevant in the modern world, our postal system really needs to work a little more like the phone system.

I can be pretty much anywhere in the US (or really, the world, if I want to pay international roaming fees), someone can dial my well-known phone number, and my phone will ring.

For ordinary first class mail, I should be able to generate unique ID numbers on the USPS's website, and associate them with any physical US address I wish at any time. Then I can keep one or more postal IDs pointed at the location(s) I actually receive mail at, and the scanners (virtually all mail is routed by optical scanners now, even hand-addressed envelopes) can just read the ID number and stamp on the current physical address.

This inspired me to register, but once again I was thwarted by the US' arcane rule banning gay men from donating. The rule applies despite the fact that I've been monogamous for ages and am tested for everything under the sun twice a year.

A college frat boy who has had unprotected sex with a different girl every week for the past semester can give blood/marrow, but monogamous, healthy gay men can't. I don't get it.

There are two links to this post on the front page right now. This one, https://groups.google.com/forum/#!topic/android-building/T4X... , loads fine on my computer and comes up in the "new" Google visual design. It completely fails on my phone (Android 2.3), displaying "Loading..." for a while and then bumping me to the front page of Google Groups with a little message saying I am now logged in (I tried several times). The other link, https://groups.google.com/group/android-building/msg/c0e01b4... , just works, everywhere, but shows the old Groups interface.

This is a really sad state of affairs. If Google can't guarantee that their fancy new Javascript-dependent links won't work everywhere, they should not be used as permalinks.

I really don't care about any arguments people might want to make about the visual redesign, or how to properly implement #! paths, or the extra effort involved in generating resilient URLs, or Google paying special attention to how the Android browser handles pages, or what evil things my phone company might be doing my my data stream, and how that's not their fault, or whatever. Permalinks should work. Everywhere. Period.

Why don't they just tag all of Honeycomb?

If the reason is that there's no combination of project commits that can create a building Honeycomb, they should just admit to it and explain why.

The current approach seems like a weird attempt to snow something over - I understand that Honeycomb was a rushed, trashy Android release, and that there's some pride involved, but supposedly all of the rushed, trashy code is in the tree now, and hence there's no going back. The first thing everyone on xda-developers is going to do is go hunting for bad Honeycomb code anyway.

Modern Web Applications are Here pocoo.org

bretthopper 4 hours ago 2 replies      
I agree that Modern Web Applications are here. The key point is that they don't have to be architected the same as Battlelog to be considered modern.

Most of us are too concerned (or straight up scared) of the JavaScript/HTML5 revolution that we can't see what is possible right now. Sharing templates server and client side is a magic bullet that everyone should be using.

Web applications are only going to get faster, and if you want to keep up, you're going to have to do implement modern solutions like Battlelog and Google+ do.

I can envision a time when full page refreshes are the exception and that isn't a bad thing.

nikcub 3 hours ago 1 reply      
With the last three projects I have started (none live, yet) the backend is nothing more than a REST API and the frontend a single HTML page with javascript, javascript, javascript.

This is what web applications are now and will be. The user experience can not be compared to the old style of application. If you are still building applications today that are GET, fetch, pause, render, etc. then you are years behind. It is awesome being able to click on a link to a 10-page forum thread or blog comment page and have it render in ~100ms.

I think all of the web server frameworks will have to adapt - from RoR to Django etc. since a lot of what they do is being moved to the client (and it becomes even cheaper to run large-scale web services because of this). There are also tons of gaps on the client side - from more capable and cachable templating engine through to a full-stack framework (something like RoR for Javascript but less confusing and hard to use than the current)

The server now is just db+REST, auth and pubsub - soon enough somebody will release a generic PaaS that does all this based on a schema. Almost no more, or very little, server-side code (unless you insist on supporting old HTML clients).

Fluxx 1 hour ago 0 replies      
While I'm excited about "modern web applications," my understanding is that they're harder to develop for and test (I haven't done one yet). If that's true, it's worth considering if the ROI is there to make your app a single-page javascript app vs how fast you can iterate via the more standard method. You may not have the traffic to where offloading rending to the client makes sense. It's likely many actions your app does are "fast enough" as well, so a rich UI experience isn't going to be a huge improvement. Reserving the highly interactive bits for where it really counts may be a better idea.

That said, it's only a matter of time before the "harder to develop and test for" goes away and rich apps will become more of the norm.

modeless 4 hours ago 2 replies      
Interesting, as Battlelog has been criticized by the gaming press including the Penny Arcade guys, who call it buggy and hard to use.

I have to say, too, that in my experience the more client-side state a web page keeps, the buggier it tends to be. Building applications this way is harder, and I hope we don't end up losing the characteristics that have made the Web so successful in the transition.

kwamenum86 4 hours ago 0 replies      
"All the pages can be rendered on both the client side via JavaScript as well as the server. How this work I cannot tell you"

There are plenty of templating engines that have been ported to Javascript. Mustache is the first example that comes to mind: http://mustache.github.com/

Once you have the templating engine the rest of the logic is pretty easy to build.

Rendering web apps entirely on the client in general is pretty awesome although there are two problems: 1) the push state API is not supported in all browsers yet, which forces you to resort the fragment identifier + onhashchange to approximate the same functionality. And of course the fragment identifier only affords you a fraction of the same luxuries as the push state API. And of course onhashchange is not supported in older browsers. 2) When you fall back to the fragment identifier rendering on the client is actually a little bit slower. The fragment identifier is not sent to the server meaning the javascript has to be loaded in the browser before anything at all is rendered. Does this lead to several seconds of delay? No. But it is noticeable. At least with push state you have the option of rendering the initial content on the server and all subsequent requests on the client without increasing complexity too much, assuming you have a good templating solution in place.

But yes I agree. Modern Web Apps are Here :)

azov 4 hours ago 4 replies      
I'm not sure I agree with the "work of beauty" statement. A browser plugin? Rendering all pages on the client via some massive JS framework? Intercepting all page loads and hooking into browser navigation? Compiling templates into Python & Javascript? Is all this complexity really justified?

I know that web apps is all the rage those days, but given the native plugin, pickiness about browser version, the fact that they apparently not care about being indexed by search engines, and all the trouble they went through to make it all work together - wouldn't they be better off to just implement the whole thing as a native app?

> The real interesting thing about Battlelog however is a Windows PC specific component. If you are heading to Battlelog from a Windows PC and you own the PC version of Battlefield 3 you can launch into a game right from within the browser. How does this work? It works with the help of a browser plugin that exposes additional functionality to the in browser client. Namely it has a function to start the game and pass it information as well as a general purpose function to ping an IP address which is used for the server browser.

Unreal did that back in 1998. They register the unreal:// protocol in windows so any hyperlinks that contain an address such as unreal:// will launch the game and connect to that ip. The good thing about this is that it can also be used by third party websites such as promoting your clans server and it is completely browser independent. I don't know if it could be abused to "rickroll-launch" the game but i haven't heard of any such incidents.

We are a startup called Glancee. We build a mobile app (iphone version + android version) that finds people in your area with friends or interests in common with you. The apps are native objective-c and java apps, and the backend is a mix of python, mondodb, and a bit of erlang.

A month ago we decided to build a facebook app to reach users that don't have a smartphone. We chose not to change one bit of code in the backend, and we were able to build the web app in 3 weeks with backbone, jquery, and websocket-js.

You can try it here: http://apps.facebook.com/glancee

The app is just one 40-line html page, the rest is javascript (and templates embedded in js). You never refresh the page when clicking a link, which gives you the feeling of using something as fast and robust as gmail.

CSS files and JS files are compressed with requirejs before being deployed, so to load the page you need three requests (plus images). Right now our biggest bottleneck is the facebook api, which is tremendously slow.

My problem with Battlelog isn't necessarily that it's browser based. My problem is that I'm forced to run 2 other system based applications on top of it. Namely Origin, the sole focus of which seems to be forcing me to buy EA games through EA exclusively.

Battlelog as a stat tracker is great. As a system of convenience run in conjunction with Origin and the actual Game EXE it sux.

It'd be interesting to see whether or not Apple changed the Siri protocol since the acquisition. Was this originally how Siri worked when it was independent?

Because Siri has roots in government contracting (it's named after SRI International, and was originally funded by DARPA) I wonder if the roots of the obfuscation start there rather than at Apple.

From what I've seen, Siri sends compressed audio to the cloud which translates that to text. What happens to the text and how does that translate to action? Where is this being handled? Is there any proof that this is done in the cloud?

I am at odds to argue with Tufte but I will. The issue with touch screens is not that they lack the same surface texture as the objects they're imitating. It's that they're imitating real world objects in the first place. I think most people would agree with sculpture and painting, that the high point of those media was reached during the point of pure abstraction. When paint was allowed to simply be paint. Painting stopped being a way to represent the real world on a canvas and was allowed to be itself, the real advantages of paint came out.

Well, let's stop pretending that the tablet is a representation of the real world, and let pixels be pixels. Why pretend they're anything more than that? "Ceci n'est pas une pipe" as Magritte so eloquently put it in '28-29.

Pixels, while not having the 3 dimensional qualities of the real world, surely have many of their own unique qualities; that while we attempt to copy the real world, remain unexplored.

zobzu 5 hours ago 8 replies      
As a owner of a Z21 I can tell much of what is said in the article is just, simply wrong and misinformed.
The author most likely didn't even touch a Z21.

DISCLAIMER: I am using Linux full time on this laptop. Some people have issues with the fingerprint or trackpad on Windows - theses are software issues which aren't present on Linux.

Fan: they're not loud. It's quieter than my MacBook. In fact, I can't hear it in a quiet room.
It's only loud when running full speed; which is rare enough. And that's not louder than the Mac.

Trackpad: it's in.. the regular spot.

Software: it's loaded with Sony stuff mostly. You can remove or reinstall if you dislike it.

Key travel: yes, it's shorter. No I don't see the issue with it, after having used it for quite a long while now. I switch to longer key travel keyboards and back to the Z21 without noticing.

The rest is just "look, my iMac design didn't change in 4 years it's awesome, changing design sucks!".

Now... let's see what the Z21 has and the others.. just plain don't.

SSD: Hello raid0 SATA3 SSDs. Have you ever reached more than 500mbyte/s read/write? Heck, sometimes its going near the 1000mbyte/s sequential. Copying stuff, reading has never been faster. Non-raid0 desktop computer with the fastest SSDs are just way slower. Won't even mention Macs with their subpar SSDs.

Screen: Hello 1920x1080 anti-glare screen. How the hell are others not all anti-glare by default ?

CPU: Hello regular voltage i7 2620M. The air CPU suddenly look.. you know.. just not in the same range.

Heat: what heat? It's extremely well extracted on the side and the rest of the system is at room temperature. Even under extreme load. A problem Apple didn't really solve by the way.

Connectivity: USB? check. USB3? check. VGA out for those conferences? Check. HDMI out /w audio? Check. Audio jack, ethernet, sdcard, lightpeak? check check check check. Tell me when the mac book air doesn't need a bunch of adapters to do more than USB.
higher power USB for charging? Heck, check again.

Weight? Lighter than the Macbook air says enough.

Battery life? Extensible well above 10H via a laptop-wide sheet. Smart. Paris-New York, no need to charge. Of course, the standard battery isn't a let down either at ~5H real time use. (they're both rated 7h and 14h max as far as I can remember, but don't quote me on that)

Now with all that, what more could there be?
Oh wait.. I mentioned a lightpeak port didn't I.. so yeah, a 600gr+ device can be added to the desk while you're not on the move.. bundling a very decent ATI graphic card, a bluray drive, and more ports. You can drive 4 screens at the same time, although its convenient only up to 3. (oh noes.)

Oh and, does it run linux properly? yep.

So it's an expensive device, but considered all the above, it's pretty decent I guess.

Finally, the actual bad, and yes, there is some bad:

Wow, what an ignorant article. I own the previous version of this (Sony does iterate...this is the 4th iteration of the Z series), and I absolutely love it. I can't speak about the new version, but the version I have has a fantastic keyboard with much more key travel than an Air. I wouldn't be shocked if Sony messed up the keyboard and trackpad though. They have a certain talent for screwing up ergonomics in the name of looks.

But really, my main issue is that this article appears to be written by someone with an agenda and little actual knowledge. The laptop's name, for example is the Z14, not that long string which is the model number. Practically all laptops, even the Air, have those model numbers associated with the specific configuration. The box for my Air has it listed on the back, in fact.

When getting my new laptop, I spent some time looking at various "ultraportable" including the MacBook Air, some Toshiba (I forget what it was called) and the Z. I ultimately chose the Sony because it was, by a nice margin, the nicest computer of the lot.

The screen is really awesome, it's incredibly fast and I actually really like the touchpad. The keyboard is not great, but none of the options I physically touched--I never saw a physical Lenovo X1; that could be good--had particularly good keyboards. The Air's keyboard was not bad, but it had an annoying layout with small arrow keys and an odd ordering of meta keys along the bottom.

Overall, I am extremely pleased with this computer and would probably buy it again, although I would also consider looking at the X1. However, an X1 configured to similar specs as the Z costs about the same and I've heard both the screen--which is really awesome on the Z--and the batter life are worse on the Lenovo.

On this topic, does anyone know of any major manufacturers who dont do this with their consumer machines?
I have had really bad experiences of late with Dell, Toshiba and HP, to the point where they come with what is essentially malware built in. As one example, our latest dell purchase redirects search queries, puts a link to ebay on the desktop which comes back once deleted, and prevents you from adding an alternative search provider to IE.

bonesinger 6 hours ago 3 replies      
I am an owner of this new Vaio Z. The laptop itself is amazing: the battery life is excellent, good performance, high quality screen (1080p), extremely fast (raid 0 SSDs will do that).

The specs are amazing for this 2.5 lb laptop, but it still doesn't do justice to how disappointed I am with the keyboard. The travel distance is so minuscule, its uncomfortable to type on. You find yourself slapping keys but feeling like you didn't really press the key. The space bar sucks, you have to hit it pretty hard to make it register.

The trackpad is pretty small and awful, 2-finger gestures only works 50% of the time. I had to disable the fingerprint reader because it would activate everytime using the touchpad (you would always hit it by mistake).

Those are literally the only 2 things I dislike about this laptop, the keyboard and touchpad. I use a portable bluetooth mouse a lot (Razer Orochi) which does alleviate a lot of the touch pad issues, but the keyboard is god awful.

That said, the power media dock is a novel feature, external graphics, blu ray and all...I haven't used it once haha. I think that's because I have a nice custom built desktop, no reason to use the PMD.

EDIT: The keyboard is worse in my opinion in comparison to a macbook air which I owned for a year before I sold it.

I just wanted to add on top that, I tested out a Lenovo T420 edge...quite possibly one of the nicest keyboards I've ever typed on.

Power supplies. I've got a copier paper box full of Sony power supplies. Every product they make has to have a different battery, plug, voltage, wattage, whatever so you MUST buy a new one if break/lose it, at a princely sum comparable to the price of the device.

Sony has 90% great, like awesome, design - then screws up the remaining 10% with either "meh, screw the user" or "hey, dig into his wallet" wrecking the rest. I've had two of their ultraportables, and try as I might to love them there's just one neurotic breakdown after another; my next is a MacBook Air.

Sometimes I think the feeling of getting "basically nothing" done by the end of the day is not the right timeframe - there are projects that have gone on for weeks that ultimately were a complete waste of time. But while working through those projects I felt something productive was happening, which made it difficult to think of them as "basically nothing". I'm not talking about failed ventures that could have turned into something great, these projects were pretty much always going to amount to nothing (they just appeared at the outset to be different to what they were)

This is really a question of short-term gain versus long-term gain as well as tasks versus goals. For short-term fulfillment, we can entertain ourselves or keep ourselves occupied in some manner, regardless of whether it's productive.

The key is figuring out how it fits into our overall strategy or goals. Is that activity or task contributing to that long-term gain? More importantly, am I actively managing it as opposed to going on blind auto-pilot (e.g. for that investment or project)?

There's no substitute for hard work, just as there's no substitute for self-awareness.

I always thought that the best way to avoid losing a lot of money is to diversify and avoid leverage.
Derivatives is leverage big time, it's speculation, not investing, you can lose much more than you invested.
Diversify and avoiding leverage as a VC would be to invest a relatively small amount
of money over many potential companies.
So can avoiding leverage to conserve your investments work the same way with time?
Leverage as a small company might be like sub'ing out your work to others. I've never read anything positive with that approach.
How about at the personal level of the article -
some wasteful activities can be avoided but stuff like email is not going away.
So leverage this down time by multitasking. It would take me 4 hours of planning for 2 hour of programming.
While I wade thought these emails I am also going to think about, plan, research, and write down what my 2 hours of programming is going to be.
During these non productive downtimes, I can get really boring jobs done, the time passes quicker,
and I have a head start when my productive time starts.

Google+ is certainly fast, I just wish it were quicker about showing me valid/updated state.

I've never used any website where the data I was seeing was so obviously out of date across the board as it is on Google+. Yes, eventually it coalesces towards correctness, but I don't think this model works well for things like notifications and such.

"Oh look I have a new notification... oh wait, no I don't, that's from like an hour ago and I already looked at it."

Speed is a feature, but so is not making your users think your software is just plain buggy and too much local state caching is basically indistinguishable from a bug for many users.. and in many contexts it can also be annoying even for those who know roughly why it is happening.

Hey, pretty cool but you should have a delay between when the user types something and when the url gets updated and a query gets made. i.e. some sort of definition of "user stopped typing". This improves usability by a ton.

Second is, maybe you should have a sidebar on the right that shows you clickable / keyboard navigatable titles of all the search results so I don't have to scroll down browsing.

Nice, but a few UX nitpicks:

* Default to sort by relevence: Put the more relevant matching properties at the top. For example, I type "backg" instead the highest result being the obscure "-webkit-background-composite" ... actually most relevant result "background" which should be the first result instead of the third.

* Default results list to condensed format: Instead of showing the full verbose docs for every matching result instead show a sparse summary of each result with a option to expand it. If there's only one matching result then show the complete doc for it

* Nice example palette for standard colors. How about an example palette for the standard font families?

Any chance of getting it to apply the filter on page load as well? It appears that it's not possible to link to a result set. i.e., if I send someone a link to http://instacss.com/#background in order for results to be shown they must perform a keypress of some sort in the search field.

edit: Apparently if you've searched something before it does display it on page load (after a brief delay)? So it seems this link might not be a good example URL. But hopefully you can just edit the URL and submit it directly to see what I'm talking about.

So let me get this straight. Not only does Microsoft have useless/trivial patents, but they shouldn't have gotten them in the first place because of prior art. Plus, with those patents they get to claim a license fee as large as the license fee for their whole OS - WP7. On top of that with those useless patents they get to act as if they owned the whole of Android, and get to dictate manufacturers how to make their Android phones?

I have no words for Microsoft, they're simply despicable and I don't know how anyone could support such a company that has proven time and time again they will adopt such tactics to destroy their competition. They've probably done a lot of this behind the scenes with Linux and other browsers before. We just didn't find out about most of it. And we almost didn't find out about this, either, if it wasn't for B&N.

But what I don't understand how could HTC, Samsung and all the others agree to this so easily? HTC has grown 3x every year for the past 2 years because of Android, and Samsung has become the largest smartphone manufacturer surpassing both Nokia and Apple thanks to Android, and they say nothing against Microsoft or try to protect the ecosystem that's been feeding them?

Shame on them for not standing up to Microsoft, and kudos to B&N, which wasn't even a manufacturer not too long ago, for having the guts to stand up Microsoft and protect the Android ecosystem.

As always, if you shouldn't look at patents, don't click to read the rest of the article.

Groklaw is right to write that. If you write software that will ever be in the public eye, you shouldn't look at software patents because they make you more liable for damages in infringement cases.

The constitution authorized congress to create a system "to promote the Progress of Science and useful Arts" by publishing information that innovators would want to look at. The system we have now hinders progress, not just in corner cases but across the entire software field.

Can you imagine anyone writing that sentence if we had a patent system that worked as intended? I can't. If the patent system promoted progress, innovators would constantly be reading patents.

recoiledsnake 17 hours ago 2 replies      
From B&N's filing:

>Microsoft has shown its intent to drive out other open source software using overaggressive patent enforcement. The Microsoft dominated MPEG-LA consortium recently sent out a request for patents that would cover Google's VP8 video codec, and one company has already filed a private antitrust complaint against MPEG-LA for this behavior.3 MPEG-LA is a patent pool organized to collect and license patents on the H.264/MPEG video codec, a method of digitally encoding video files and decoding them for playback. Google is attempting to introduce its own codec, the VP8 codec, to compete with the MPEG codec. Once again, by seeking non-essential patents to assert offensively rather than defensively, Microsoft intends to drive out competition from open source developers.

Is MPEG-LA really dominated by MS in any sense of the word? Just curious.

MS seems to be actually paying them more for licenses in the end than what they get for a few patents they have in the pool. Not sure about Apple.

In any case, they're supporting VP8/WebM via user installed plugins in IE and have stated that they're not shipping it with the OS because they're afraid of patent trolls suing them for very high damages because they would be liable for hundreds of millions of Windows licenses.

Igor_Bratnikov 17 hours ago 3 replies      
As someone that has been on the defending side (legal representative) of a patent troll attack which is essentially the role MS is playing here it saddens you to see how low people can go with using the patent system. One of the case I analyzed was a patent that literally did not cover the technology and only a very loosely interpreting judge could interpret it as so. But the cost (at least 0.5 - 1 million dollars until a judge will even see your argument) are so staggering that we in fact encourage parties to throw around bs patents to racketeer money from parties that actually contribute positively to society by creating innovative products. Of course this also fuels the market for filing and selling/buying up bs patents.

The only way I can describe it is that its like a artery of someone that keeps eating bacon long after their doctor advised them to stop. The space keeps getting blocked up more and more. It is inevitable that serious problems are bound to occur and cause ever greater friction to innovation.
