"If you have personalized pages (ie: majority logged-in users) this approach isn't going to work. "

I've considered this problem, and am working on a solution for nirvana[1]. The biggest challenge to this project has been to take a language (coffeescript) that is sequential and run it in a distributed environment, without the programmer having to know distributed programming. One of the techniques I'm applying is making a response (in this case, a web page) the result of a collection of components, which are rendered separately in the same context. (EG: The context is the headers of the request, plus the user record if the user is logged in, etc.)

So, the request comes in, the components are loaded from the cache, they are executed (in parallel) all with a copy of the state, their results are aggregated and that result can run thru templating to produce a webpage that is returned.

The idea then becomes, instead of executing the code for every component in every request, if the component has no context specific requirements (e.g.: it is the same for every user, it's a static element, or it's dynamic, and but doesn't need to be generated every time) .. then it can be flagged as cacheable. The caching would also have a staleness factor (Eg: 1m, 5m 10m).[2]

My hope is that you can have pages that are custom per user, but that also contain heavy impact results (say a graph produced by an expensive operation), where the results come form cache, the static components come from cache, but the user specific parts are dynamically generated each request.

This component approach not only lets the code be rendered in parallel, and often not even rendered, but instead pulled from cache, but it should allow for more convenient re-use of common elements and features across a site.

I hadn't considered caching for just 1s, though. Will have to think about that.

[2] Planned. There are some implications of this that will require tradeoffs, so initially it may just be a flag of Yes/No for "Cache for up to 1 minute." or some value like that.

The bigger question is why wasn't this considered DURING the iOS5 beta? If it got brought to Apple's attention during the beta cycles and they decided to not fix it then they'll most likely won't fix it now either (although it seems like they really don't have much choice here but to provide a solution one way or another)
My "status-symbol widget" is going to allow me to make a cross country flight tomorrow without carrying three sectional charts, a terminal area chart, and an airport/FBO directory. It will retain a GPS fix the entire flight, creating a moving map out of a VFR sectional chart and serving as an unofficial backup to the panel-mounted GPS.

Once I land I'll use the same "status-symbol widget" to check my email and respond to any particularly urgent requests; I'll use the same device to call my wife and tell her I'm on the ground safely. Might even take a picture to send to her if I feel like it.

Then I'll get in my rental car, where I'll use my "status-symbol widget" to help me get to my ultimate destination, a hotel room I booked using the same device that's going to help me get there.

Once there, I'll fire up the device to find someplace good to eat.

I was actually just looking into this right before this was posted.

A big pain is setting up a Virtual Box just to use the server. Wish there were a Windows version of that. I also wish there were demos for other (non-isometric) multiplayer games. There's video of a platformer, but there's no live demo for it (nor is it multiplayer, far as I can tell.)

Still this is the best starting block for an HTML5/Node.js online game engine I can find. Will definitely be looking more into it.
Guess it's time I get a google+ account.

At the end of iD's Doom II, the final boss produces a repeated "kafoomBOOM" sound.

That sound, like the Wilheim Scream, shows up freaking EVERYWHERE (ok, not quite that bad but it seems that way). Dunno if anyone else notices it, but it has reminded me of that game at least monthly for over 15 years.

Yeah, audio hacked this gamer's memory all right.
that happened to steven wright too. except that his house started. so he took it for a drive. parked it on the freeway and screamed at everyone to get off of his driveway.

Show HN: Create a beautiful timeline with TimeKiwi
As a parent, I would be very wary of exposing a child that small to any screen for extended periods of time.
This was a weekend project and started as a proof of concept that a timeline can be created completely on the client side. That's why don't get fooled by the occasional choking of our kiwi squeezer, it's just the APIs that are unstable.

Depending on the feedback we'll receive, we also have a business version in the works.

Unless you were naive enough to buy the X220 with the "Thinkpad b/g/n"[1] wireless option. Then, grief, anger, acceptance/resignation (in the form of a USB wireless stick[2]).

There is a host of other issues, but nothing that can't be worked around after hours of researching blog posts and manuals. More kernel panics on suspend (related to the aforementioned USB wireless), external monitor issues, USB 3 port disappearing ... You know, small stuff.

> Those that have dozens of tabs open - I do think you need to ask yourself why?

Spatial memory. If my tabs are not exactly where I left them last week, I utterly forget what I was doing. (I'm one of those people whose room looks like a mess but I can tell you where anything is -- so long as no-one's moved it.)

If tabs are slowing things down, then the browser should "background" tabs that haven't been used in a while. (I'd say swap them to disk but the OS does this already!) Pause Javascript, Flash, etc.
Here's a great TED talk discussing how babies this age go about learning how to deal with the world. Essentially there's a lot of experimentation as other folks have commented on but there's a part towards the end about how they seem to use a super sophisticated statistical model of the world to figure out the odds of things working. http://www.ted.com/talks/alison_gopnik_what_do_babies_think....
I remember reading an article of the difference between 2 year olds and 3 year olds. A two year old will see a picture of a shoe and try to put their foot in it whereas a 3 year old realizes that the picture is only a picture.

I imagine the 1 year old in the video is also falling into the 2 year old trap. But as people have commented this is just how learn and how our brains develop.

That usage pattern only exists because 32-bit Ubuntu is selected by default and marked as "recommended" on your download page. People I know regularly download the 32-bit version even though I tell them to get the 64-bit version.

Why is 64-bit not the recommended option?
Hey guys, appreciate the comments... I'm the dev over at www.isogenicengine.com. The demos are still works in progress and mobile support is coming soon.

I'm just one guy working on this in my spare time (I have a full-time day job too) so things move a little slower sometimes that I would like! Currently looking for investment to get a full team to help!

Regarding the Node.js requirement, there is an offline version of the engine that runs on any standard web-host. It has all the network and server-side code stripped out.

Agree that the demo page has a lot to read, but it's written for developers rather than players so tech info is there to explain what the demo is showing (and what it's not).

A much more complete demo is on it's way I promise! :)

You weren't watching and consuming full length feature films on a Mac+. Neither was I.

Context is one thing (i.e., mouse, keyboard, MacPaint) and I agree that two year olds adapt to context amazingly.

Media is another thing entirely though. Context and media in intuitive ways will have far reaching ramifications.
Tab Groups. For those of us who do lots of research and like to keep it organized it's a godsend.

Right now I have 159 tabs open -- I was curious so I decided to count. If I tried that in Chrome I'm pretty sure it would crash and burn hard, not to mention there would be no ability to keep it organized.

I know there are some research workflows that would allow me to do that as well, but I haven't really taken the time to dive into them after I found tab groups.
Miss Representation – Trailer
I'd like to see more search engines come into the picture, but from using this, I'm not sure I understand how the results are more relevant than what Google provides.
If you type in the name of someone well known, you get a box with some info about them - mostly from wikipedia,but couple of other sources. If you are relatively unknown, the results are the typical linkedin, spoke.com, myliving, etc. etc.

For someone to really switch over from Google, the results cannot be as good as. Bing was as good as, and it hasn't really worked out so well for them. With as good as - there's no compelling reason to switch. It has to be substantially better, and I don't see it but I could be completely wrong.
I'd be happy for someone to reply to this with example search terms where the results from DDG are far better than what Google provides.
My son (not quite 2) engages in all these same behaviors. He pokes things, points at things, touches things, checks to make sure his finger is still attached, pokes things some more... and he's been doing it since long before he was allowed to touch the tablet computer.

Sometimes when he touches, say, pictures in a newspaper or magazine, he's just trying to get daddy's input (same as when he touches something in a board book.) He touches a picture, and I'll say "it's a blue car!" or "what a furry kitty!" You might mistake it for "thinking the newspaper is a broken tablet", but not for long.

Amazon is selling about 50k android tablets a day. That sounds like a market to me.
If screen damage rates are much higher, then yes, it could indicate a design flaw.

As for the speaker, if I have to set my phone face down to hear the alarm, that's a design flaw. If the Nexus designers believe that a louder speaker is more important, that's valid, but it's not valid if the extra volume is muffled when placed on a surface in the natural fashion.

It also really f*cks with rapid multitasking between multiple applications/windows, which is a mode of operation far more common on Linux systems than Windows/Macs, in my experience.
Its not so much that material is on the phone its how its handled as far as access.

Let me explain, you can already secure encrypt stuff with android 3.0. So in hardening the kernel they are shutting down avenues of attack to get at stuff that may be stored on the smart phone.

However, in this case its not Google who has the remote erase and lock commands but NSA/CIA/Military..so if phone goes missing its sent a remote erase and lock command..
Love. Love yourself, fall in love, love what you do. Pick whatever order works best for you.

It sounds like you've figured out quite a bit about yourself at a surprisingly early age, had a chance to see a decent amount of the world already, and have had to grow up very quickly. In any case, find something external that really, truly matters to you. Know thine self, etc.
Hey, could you let me know what bugs you saw and what browser you were using? Cheers!
I found the article to be quite informative and, why not, just. Readers that are not acquainted with hacker culture will be able to know who Dennis Ritchie was and comprehend his importance after reading it.

Moreover, it is not one piece of the 'sad elitism' that took place after the news about dmr arrived. I saw some dozens of comments splattered over different places following the line 'you must definitely know who he was,' accompanied by some generic complaint about unfair coverage by news media over Mr. Jobs passing. Though I agree with some of these views, I don't think it makes the fair eulogy Dennis Ritchie deserves.

Dennis' importance will never be measured by any kind of comparison or relativization; it is hugely obvious, it persisted and is going to persist by many decades. We here know it. Those who don't, though, have the right to understand what he made possible. I think the article succeeds on this purpose.
Define "regularly", he's talking about 15 minutes. I don't know that I'd even want it done that often. This is not critical data, let the filesystem layers do their job, at which point the RAM used by keeping a (very small, in any event) working set cached is also irrelevant as the filesystem cache takes over.
How do you know if they are using it? Maybe you're not in often used circles of a lot of the people you invited.

Spikes of 2000/second are not unrealistic, and part of the problem is that once the spike hits, inadequately designed applications start to wedge on lock contentions and just plain inadequate CPU, the VM layer starts swapping, people trying to get to your site start hitting reload (humans do not have an exponential back-off function), and the whole thing comes crashing down until traffic drops off to more sustainable levels.
"If tabs are slowing things down, then the browser should "background" tabs that haven't been used in a while. (I'd say swap them to disk but the OS does this already!) Pause Javascript, Flash, etc."

This would massively break the web. Even throttling setTimeout() calls for tabs in the background caused breakage.
Aphyr, every single browser engine has longstanding bugs; it's just a matter of priorities.

WebKit doesn't have load events for stylesheets either, for example. It has buggy CSS selector matching, on purpose (doing the right thing was deemed too slow). There are multi-year-open bugs in V8 and Chrome, and that whole project hasn't even had an open bug database for more than a few years.

So I'm not sure the development culture is any different. You just haven't had a chance yet to file a bug and get it ignored by the WebKit folks for a few years. It happens all the time....
So you have phone GPS (like many phones) and you can read your email (like many phones) and you can make calls (like most phones) and you can use it to browse web pages. There have been small electronic devices doing combinations of these things for a long time, none of this is in any way exclusive or original to the iPhone. This all rests on decades of preceding technology not proprietary to Apple. Steve Jobs didn't make it new, he just made it white.

It's always very sad when a human being dies. But excuse me if I don't worship the corporate hero who produced the object you use to do things which aren't necessary using non-unique technology.

I'll grant that one thing Steve Jobs did develop was the brand strategy that makes you rabid when someone challenges your decision of buying small electronic devices you don't need at a significant markup, because it's become a part of your personal identity.

Good security is done in the light. The NSA wrote SELinux, after all. It would make sense for them to encourage this hardened version get used outside of the government.
Both of your examples are definitely worse on OS X than on basically every other OS in existence. And as proof, OS X is slowly but surely moving in the direction away from at least one of those, and I'd bet that within two or three revs of OS X away from both.

Menus just aren't that hard to hit otherwise all clickable items in a program should be on a screen edge. In fact, according to Fitts's law, they should be jammed into the corners of the screen since that's even easier to hit than a screen edge. But they aren't because it's not that hard for anybody who's bothered to use a pointing device in the last 20 years. More important than that, trackpads are becoming the de facto pointing device on Apple sold computers and Fitts's law works differently on a pad vs. a moving device like a mouse. The edge of the touch surface is the infinite target, not the screen. Since touch devices are not 1:1 mapped to screen area, all clickable interfaces should be at the edge of the pad relative to wherever the cursor starts.

Likewise, a second mouse button turns out to have been a great idea, so great that decades later Apple guarantees that they not only support right mouse buttons, but their default mouse not only ships with support for it, but they even have managed to cram a touchpad into it and their trackpad recognizes a two finger tap as a right-click. Why? Because decades into the great GUI experiment it finally dawned on somebody that interface complexity requires more than one button -- otherwise half of your interface gets buried behind a modifier button (or two or three) or a pile of menus and your sole button.

I've watched many dozens of users move to OS X and one of the first things they ask is "why is the menu bar way the hell over there?" -- with pointing to the top of the screen (or to an entirely different monitor depending) usually preceded by a series of questions about how to do some function that is clearly on the menu bar, but since it's not coupled to the actual program window, they assume it has a decoupled function from the program and don't realize what they are looking for is there.

It's an embarrassingly repeatable user interface experiment that's left me convinced that the only reason it's still part of the OS is to differentiate OS X from Windows.

Physically decoupling software interfaces from the software is almost always a bad GUI idea if you can help it. It repeatedly confused users, particularly new users. It's like putting the steering wheel of your car in your house, and the gas pedal in your back yard shed.

Everything from MDI to full screen apps are now slowly creeping into OS X because time and time again it's shown that users find those alternatives more usable than the old Apple way standby.

Lets stop tooting this "everything Apple does in UI is best" horn. Lots of stuff Apple does in UI is great, it's even the best, these things are simply not.

It's a mile and four intervening windows all activated via focus-follows-mouse away.

On Macs, fer love of Pete, the Mile High Menu ... is on the other display.

Menus just f@cking suck anyway. I've canned my browser menus via Vimperator (on Firefox / Iceweasel). Sure, I'm a power user and I know what I want to do and I've got finger memory five miles deep (plus command completion). So suck on that teat.

Fipp's Law optimizes for one case: mouse navigation. Sure, it's nice to have a big fat landing zone, when you need it. But often you don't, and the optimization unambiguously and indisputably breaks numerous other optimizations. Which frankly I care a whole f@ck of a lot more for.

We're talking about desktop (or large laptop) displays here. For tablets and small-factor handhelds, there are other considerations. Which is why UI design is complicated and a task and disipline worthy of research and nuanced understanding.

The 1980s were 30 years ago. Go ahead and pop up a 512x342 window on your desktop. On my not-extravagant dual-head display, I can stack those up 6.5 across and three high. With window decorations.

Y'know, I credit Jobs with some good stuff, and he was nothing if not persistent in believing what he believed in. But some things really have to go.
I don't think cryopreservation is that likely to work. Even its proponents are not that confident in it. I've collected some estimates:

Under a different set of circumstances, Natty could have been said to be flawless on my T420, and indeed I thought it was for the first few days. When I started using the system more intensively for the tasks I bought it for, I began to notice the problems.

I'm very rarely on a plane. However I take the subway every day, and I'm extremely thankful that Tweetbot, Reeder and Newsstand cache everything so that I have something to read. I also don't consider the subway a niche or isolated pocket.

I just don't buy the lame justification about not always being connected. If you don't want to be connected, turn off your damn phone. Don't insist that everyone else shouldn't be able to enjoy their time the way they want to because you associate your mobile device with stress.
I too bet the camera is awesome, but these were released images from Apple claiming that they were taken with the 4S and not edited in anyway. Not really sure as that counts as a true test.
