Yeah, I have a 2010 11" MBA, and I'm thinking about the upgrade. I really wish they'd bumped the max RAM up to 8GB; Eclipse for Android development is cramped in 4GB with other stuff running. I'm a little worried about the Intel graphics as well.

The upgrade is also a little more expensive, too. I think I paid $1500 for the maxed-out 11" last year, but maxing out the new 11" costs $1650.

But the Core i7 and 256GB SSD are very tempting. I dual-boot OSX and Linux, and 128GB is starting to feel a bit cramped. I was looking around at aftermarket SSD upgrades for my existing Air, and an off-the-shelf upgrade to 240GB would cost me $520, which is a third of the cost of the laptop! I could probably sell my current one for $800-$1k, and get the new one for $1650 without breaking the bank.

Nevermind all the plugins and bundles

Whether it fits your taste or not, ignoring the plugins and bundles is missing the whole picture. The bundle system together with the fact that it has had a large and strong community backing it up for years is a major, major plus. There are existing bundles out there for almost everything, often even for obscure frameworks/languages. For example, if you don't think you'd want commands or snippets to toy around with new languages, think about syntax highlighting.
last year i stepped away from the apple brand. just much happier going the FOSS route.

i now have a thinkpad x220 running gentoo with the following options: IPS display, 2.7GHz core i7, 8GB 10666 RAM, 160GB intel SSD, bluetooth3, usb3, 3 usb ports (one always on), sdhc, express slot, displayport, vga, and a 15 hour battery. size is 12.5" and weight is about 3.5 pounds.

i also got a docking station for it (oh i missed those when i was a mac user), which is connected to a 2560x1440 27" display via a display port. the intelHD3000 graphics card is the same one used on the airs and for the integrated graphics on the pros so video performance is similar, while other hardware performance is much better.

i got a reasonably good deal on all of it and i likely wouldn't go back to apple with this setup. the only [minor] annoyance is that the 12.5" screen is only 1366x768. it could be a little better, but it's workable and as i wanted an ultraportable, it's not bad. the IPS option really makes for a beautiful screen.
Earlier we were totally interested in ZFS, as it would replace RAID & LVM as well (and ZFS gets great reviews). But (to my understanding) native ZFS is not available on Linux and we're not really looking to switch to OpenSolaris.

ANOTHER option down this line of thinking is switching to btrfs, but we haven't played with it yet.

By the way, at Backblaze I've felt like we have had to implement several things that I would have guessed would be standard "off the shelf". One example: When a customer wants to download a restore file with a web browser, are you aware there are no checksums for over-the-network transfers other than the built in (completely unacceptable) 16-bit TCP checksum? You are virtually guaranteed to have an undetected corruption within 30 Gbytes of download, which is basically what we like to call "a totally average customer restore". So Backblaze had to write our own custom reliable, restartable "downloader". It boggles my mind that the whole internet is throwing undetected errors on HTTP downloads and nobody cares to fix the protocol?!! Where the heck is Google, Apple, Facebook, Microsoft, or <insert standards body> defining a standard for web browser downloads larger than a few GBytes?
And since they block even visitors from Tor I do not ever visit it. I would not go near that site without protecting my identity/privacy.

>Is "regulatory capture" the latest buzz phrase from Frank Luntz?

Beats me. But you're delusional if you think regulations are created by disinterested people contemplating the public good.

We live in a world where Fannie and Freddie debt was regulated as Tier I capital, for goodness sake. We live in a world that requires (black) hair-braiders to pass a 400 hour course on cutting (white) people's hair to open up shop. We live in a world that caps San Francisco taxi cabs at approximately 1% of the number demanded. The evidence demands at least a slightly cynical evaluation of the regulatory state.

I don't think I've ever watched Fox News or listened to Limbaugh, by the way, at least not for more than 5 minutes in a waiting room. You can leave the ad hominem at home.
What is wrong with that quote? When discussing common criticisms of Mork, wikipedia states that: "The conflicting requirements gave Mork several suboptimal qualities. For example, despite the aim of efficiency, storing Unicode text takes three or six bytes per character."
"It chose to attack the lowest-hanging fruit first, the one thing about Apple's development environment most likely to stand out as primitive and backwards to programmers coming from other platforms or even fresh out of school: manual memory management."

ARC works great until you have cyclic references. Then you "just" have to add "Zeroing Weak References". Ok. Where? How do I know when I have to add them?

The problem with reference counted memory management is NOT having to type [x retain]. Its having to KNOW where NOT to type it. ARC doesn't solve this at all. It just allows an entire generation of programmers to stop thinking about it altogether. That's going to end well.
Agreed. I posted something similar in a comment yesterday:

"BTW, a lot of these people are pretty committed athletes. If you're not, and you're looking for something that's easy and obvious, try doing some pushups throughout the day. When I'm feeling antsy, sometimes I get up, do 20 pushups, and then go back to what I'm doing. Start small: two pushups count if you're not used to them.

I like to run, and if you're starting out, it's relatively easy to buy a pair of running shoes (try going to a running shop with a pair of shoes you already own; the staff should be able to look at your wear pattern and adjust the shoe they recommend accordingly) or a pair of Vibram Five-Fingers. Start easily: go out running for five minutes. Or ten minutes. Build up little by little.

Otherwise, I think the meta-advice of this article is that we make time for things that're important to us, which most of us probably already know, or know on some level."

It looks like they've done more than just adding filtering options; apparently you can now retroactively query the entire analytics data set for your site, in real time.

In my experience, this sort of feature lets you ask questions that iteratively lead to more questions, and eventually to useful/interesting conclusions.
Haha. No, I think if we do anything like that, it'll probably be via Mercurial.

See my other post on this. It is extremely simple XML anybody would understand instantly. In fact, some people have already scripted changes to the XML files running on Mac to increase the "throttle" at night and decrease the "throttle" during the day. We'll be giving the Linux client some more thought over the next few days.
I like the way CrashPlan works. I use it to back up both Windows and Solaris. The GUI is Java, but I only run it on Windows; the GUI communicates over TCP to the Solaris machine. This seems to me the best compromise.

Similarly, the CrashPlan service itself is written in Java and for binary compatibility, only relies on a little binary library loaded via JNI to accommodate the differences between Linux and Solaris, not to mention Windows and Mac. It doesn't even support Nexenta (OpenSolaris kernel + Debian userland) directly out of the box, but I was able to hand-combine the bits from Linux and Solaris installs to get something working: the moral being, for OSes targeted towards more technically adept users, you may not need as much work as you think, if your app is self-contained enough.

Pushups should be balanced with rows. You balance a motion with a similar counter-motion. Pushups are a horizontal push, pull-ups are a vertical pull.

Why is Twitter so slow to find a good business model, while Facebook is profitable?
The best solution I've found: I lie on all my security questions.

Give your father's middle name instead of your mother's maiden name, or something. As long as you're consistent in your lies, it's not hard to keep track of.
Thinking about it further, I'd bet the distinction is that iTunes is on Windows too, so it's viewed as an independent product, while things like Xcode and FaceTime are tied to Mac OS.
I don't know, I'd have the same first reaction. How many undergraduates even own a suit? I don't think I or any of my friends owned a suit until long after graduation.

Maybe. But I also feel like if you go to Harvard and have the ability to get an appointment set up by a friend of the family, you would maybe "understand" where they're coming from a bit more. (I use understand in the idea of recognizing that they're trying to emulate businessmen and treat such a thing as a business transaction.)
Almost very undergraduate I know owns at least one suit... Granted, they're not all Armani suits, but I think you'd be hard pressed to find a second-year or higher student these days who doesn't have at least one suit.
They need to prove that the defendant willfully downloaded the file at a particular point with the intention of violating copyright

No, all that is needed to prove is "making available". Even if you ripped your legally purchased CDs, and then installed Kazaa, which then detected the mp3s on your computer, and then began sharing them, without your knowledge, you would still be liable.

Infringement really has nothing to do with intent unless you are attempting to argue fair-use.

I hope this isn't bad news for Swiffy, the very cool Flash->HTML5 converter they launched not long ago. Hopefully they'll commit to licensing the runtime so that people can continue to use their converted files. If they take it down, existing Swiffy conversions will stop working, and right now it says "All Rights Reserved" at the top of the runtime they host.

Anyone know if there are any plans to open source projects like this, or if there's a way to get in touch with someone who could do so? I've submitted feedback to their feedback form, but I'm not sure if it will be seen.

I was also very surprised by Mr. Summmers' response. I went to NYU where John Sexton (president of the University) would often be seen in jeans and a sweatshirt. That being said, it was not uncommon for students to be in suits and ties for various functions. I mean, when you're paying >$30k a year, I feel like the idea of wearing a suit to a meeting with someone isn't outlandish.

I seem to be able to only see 1 weeks' worth of historical data, though, so I am not sure if that's user error or some other limitation.

This site was created by my startup, Tomnod.com, to help the World Bank catalog buildings damaged by the 6.3 earthquake that hit Christchurch on Feb 22. Users compare Google Maps before-quake imagery with ultra-high resolution aerial photos taken 2 days after the quake and identify buildings that have been damaged or destroyed.

Tomnod's vision is to build this into a go-to source for rapid disaster relief and crowd assessments following future disasters.

All feedback is most welcome!

"with the power of Retweets, reshare on facebook and Google plus. U.S army propaganda will eventually reach US domestic audience and thus mislead them about the conduct of U.S foreign policy." thus it is illegal by a U.S LAw: The U.S Smith-Mundt Act pointing propaganda campaigns at US audiences is illegal.

Yikes, what? We all run Lion here at Backblaze and it works flawlessly for us, and our internal stats show THOUSANDS of Lion customers happily backing up. If you can provide more details of your setup we would LOVE to fix that for you. Since Mac customers make up more than half our customer base, we're completely, 100 percent dedicated to Lion. Send us info or contact us at our company name at twitter or facebook or use the help links off the homepage.

As a side note -> Backblaze only does one thing -> HTTPS POST. In user space. We do NOT extend the kernel, we do not have drivers (at all), we simply read files (we don't even write to your files), compress and encrypt them in RAM, and push them through the completely common HTTPS. It is unusual for Backblaze to cause any problems except a sluggish network or a hiccup in a skype phone call.

Tankster: HTML5 Multiplayer Game
General nitpick for articles like this: if you improved X about your service by switching from application A to application B, simply say it. Phrasing like that used in this article implies (falsely) that Zencoder wrote their own encoder.

"We made our web server 5 times faster!" might sound amazing, but if you really mean "we switched from Apache to Nginx", it's misleading.

Also, FAAC is widely known to be pretty bad. Even LAME MP3 is quite a bit better at 128kbps, to say nothing of Vorbis, good AAC encoders like Nero or Apple, and Opus/CELT.
AFAIK MS seems to be doing this too, BTW.
Because Twitter is innovative, while Facebook is just f'in huge?
>Terrible advice. Use NIO and do it properly. Creating 1 thread per connection is for unskilled programmers.

Depends on the application. If the connection is handling real-time financial data(for example), there might be enough heavy lifting on the data stream to warrant one thread per connection. A good programmer wouldn't have too many of these threads running on a given machine, however, because one thread can easily consume a full CPU core, and still need more.

For connections that aren't doing much work, it's definitely better to aggregate connections onto a much smaller number of threads to avoid context switches.

>In my experience once you get up to about 1k threads in Java you'll be wasting most of the CPU up switching between them.

I agree. Thread context switching is extremely expensive. I've seen 10 thread applications consume full CPU time with context switches alone. There are a lot of tricks that can be done to mitigate it, like binding threads to certain CPU cores, making sure that threads that are communicating with each other are on the same CPU to avoid L2/L3 cache thrashing, etc. It's a lot of work, and requires a lot of knowledge about the code and system, but the results are staggeringly good. We've seen performance boosts on the order of 25% with single threaded applications, and boosts around 30-40% for multithreaded apps. Almost all of this is done outside the application code, however.

I can't imagine any reason why you'd have 1k threads running on the same box in one process, to be honest. 1k+ threads seems to indicate a lot of threads doing very little work. If they're doing basically nothing, consuming less than 1% of the CPU each, it's better to try to consolidate the work they're doing into a much smaller number of threads. It's a lot of work, but will get pretty considerable performance gains.
Webinar: How Kids are Envisioning the Future of Content & Technology
Why try and achieve something hard like profitability when you can easily be valued at $8b and raise $800m to keep that going?

I don't mean to be too critical but sometimes I wonder if this is better than, say, Twitter finding out that it can't make more than some small amount of money in profit.
Remind me of this one with the weather balloon and the iPhone:

The Tesla roadster was purely a tech demo, a proof-of-concept. Tesla knows that, and they knew it from day one.
Can you comment on which actual encoder you're now using, or do you consider that a secret?
Facebook is profitable, yes. Most of people (edit: instead of most I said '99%' but that's not true so I updated) use FB from their browser going to facebook.com (or searching facebook on Google and clicking the first link), while Twitter is used mostly in desktop/mobile apps.

It's a bit more difficult to develop a business model for Twitter than for Facebook, which is profitable with "just put ads on the right of everypage".

But: shouldn't a company as huge as FB be many times more profitable that they are right now? (400M$ in profits in 2010: http://dealbook.nytimes.com/2011/01/06/goldman-unit-passed-o... at a 75B$ valuation if I recall correctly).

Anyway, my point is Twitter & FB business models are not & i'd guess won't even be similar, and it'd difficult to compare them.
I wonder if the team also showers together afterwards or just smells bad for the rest of the day.
