I don't know, I always found the notion that humans will always be able to optimize better than machines to be somewhat... naïve. Is it an NP complete problem our own heuristics are currently better at estimating?

No one has performed controlled studies on these things - maybe they had some crummy bottlenecks, used some language feature that their compiler couldn't optimize away, maybe the benchmarks they use to determine performance are trivial (which is very often the case), etc.

Not to mention that most of an operating system's time, post boot is spent doing... what? Having the scheduler swap processes in and out? If you're running a single program that fits inside ram... it's totally fucking pointless, there's nothing left to optimize.

I have a better question. These guys are clearly smart. What the hell are they still doing in Atwood, Ontario?

I'm the software development director here at Ergotron. The purpose of Juststand.org is to bring awareness to the benefits of standing and the risks of sitting too much. Will we benefit from that awareness? Yes, we hope so. But the purpose of the site is not to just simply push our product. On the products page of juststand.org we link to some competitors products as well as our own. http://www.juststand.org/tabid/660/language/en-US/default.as...
The development environment on the Lisp Machines is an example of something that we've "lost", but the examples in this article either still exist, weren't that useful, or have been replaced with something better.

And Emacs or Vim can do anything and more than the editors mentioned in this article.
How many hours a week do you need to spend for 4 courses?

As you'd expect, it varies substantially person to person. Nominally, each course should take up 12 hours per week, including time spent in class (n units means n hours per week spent on the class). In practice, it can be anywhere from 50% to 300% of that or more. Most people at the extreme top end of the range end up dropping the class, so the top side is pretty well bounded.

Are there any known people who go to these hard courses without spending as much time as supposedly required?

Sure. When I was a TA (for an advanced control theory class), there was a huge range of time spent. Some people never showed up for class and did great; others came to every class, recitation, and all of my office hours (that alone constitutes ~10 hours per week) and reported spending another 6 to 10 hours on each problem set, and probably double or triple that on each lab.

Most of my undergrad career I took 5 classes a term, and I did my absolute best never to study from Friday afternoon until Sunday afternoon. As long as I stuck to my schedule, it was completely doable. Of course, I skipped classes and recitations that I found unhelpful in order to reduce wasted time.
Compilers are great at some things and really bad at other things. The C and Fortran ABIs are too permissive in some cases, making certain optimizations impossible for the compiler to do (without combinatorial growth in generated code size). On x86-64, you can go a long way using SSE intrinsics, but that is pretty close to the assembly level. IBM did a bad job designing the PowerPC intrinsics, so they are nearly useless. There are a few computational kernels that I have sped up by a factor of two relative to what the compiler could produce or the best published result. The x264 project writes a huge amount of assembly and provides consistently better performance than other implementations. There is still a place for assembly, although it should be kept localized.

I spent a few minutes trying to figure out what Lift is but didn't get enough information scent from the introduction to persevere. I did pick up that Lift is not too interested in solving any persistence problems.

For what I'm working on (multiplayer, offline/online web application) persistence has taken the most work to get right. It has to be done at the framework level. An offline web app has to deal with synchronization (backporting of data, client-side data loss or corruption, client-side clock issues, GBs of data per user, multiple users sharing the same data), client-side and server-side migrations (code, data, schema), browser-side database (indexing, memory usage) etc.

Partition-tolerant persistence is almost exactly what I'd want a web app framework (as opposed to web site framework) to be tackling. I'm not aware of any frameworks (including Backbone, Lift, Rails etc.) that do.

Well, since the TSA aren't law enforcement, they can't legally detain anyone - they rely on the police (local / state) for enforcement. Technically, Texas could have their officers refuse to detain those the TSA refused to clear.

At that point, the feds would need to step in with either the FBI or Federal Marshalls to prevent fliers from boarding planes.
Brandon,

I found this answer very insightful. I'd ask to ask you one or two more questions via email.

I don't see one on your profile though. Can you post it here?

Or email me at tapha@live.co.uk and i'll get right back to you.

Many of them can be done remotely, as has been done at Pwn20wn for several years on OSX.

But to actually create a weaponized attack that can get on a lot of machines requires a fair bit of work. If you're going to do that, it's probably worth going the extra mile and attacking a much larger installed user base.

But, what's even easier is just doing malware that the user installs. You can write it in a fraction of the time, and you probably get similar infection rates.
I think that this is common to any expressive language in a business setting. Small, expressive code is easier to read/write/maintain for the person who originally created it, as it matches their brain and way of thinking. However, once you encounter an ever-changing set of people who may want to consume or modify your code, you need to give people a look into how your mind works. Narratives are often much longer than normal quick remarks in comments.

Furthermore, this source is intended for educating :-)
You certainly have the freedom as a user. However, imo, what's been missing since day 1 is any sort of moderately understandable UI for controlling this. Most people understand the basics of bookmarking. If we had some browser UI with 3 or 4 lights (red/green/yellow, etc) that we could click to allow some or all cookies on a per site basis, people would have a sense of control over all this stuff (just like they do bookmarking).

The problem comes in when 'cookies' are intermingled with the word 'privacy', and control over that is typically buried multiple levels away in swathes of technomumbo.

That's listed in 'under the hood', which non techies would probably shy away from. Even if I go there, I have to 'manage exceptions' and decide whether to 'block third party cookies from bet set' (while at the same time having to ignore exceptions if I want to block third party cookies).

I know this stuff inside and out and it's confusing to me. I understand the geek need for 'low-level controls to tweak everything how I want it!' but for goodness' sake - if we have a few up-front always visible controls in a user-friendly manner, the EU ministers could block cookies all day long, understand how to do it, and understand anyone else could do it too. It would not have the appearance of the black magic it does now.

Can we just get something simple like the ability to undo window changes? Undo: z-order, window activate/focus change, position, window moves, resizing. How many times did you bring a bunch of windows to the front and then accidentally click on window in the background? We could use an easy to remember shortcut key like Windows/Apple/Super + Z and + Y to redo.

Emacs have it. http://www.emacswiki.org/emacs/WinnerMode

Can we also get a way to move windows on the z axis or change its z-order? Windows/Apple/Super + scroll wheel. I want to push back or pull windows.

How about a way to multi-select windows (like Ctrl/Command + click with files/listboxes) and move or tile only selected windows?

The solution is: a) stop using analytics and ads that set cookies or b) put an annoying dialog on your site.

I have to do some more research before I decide for sure where I stand on this issue, but I strongly suspect that the tech community is indulging in a little entitlement here.

As important as cookie tracking is to web developers, the vast majority of voting citizens do not believe they are deriving any value from it and do believe that it is a potential threat to their privacy. These beliefs seem reasonable to me.

It may be a financial blow to web businesses but I don't think it hurts any of the things that make the web valuable to people at large.

This is the kind of democracy that people scream for here: listening to citizens and citizens only. It kind of sucks when you are the corporate special interest being trampled on.

"1 in 3 prisoners are businessmen." Bullshit. The reporter probably misquoted his source or "Business Solidarity" is simply pulling numbers out of their ass for shock value- BBC has never been a friend of Russia so is happy to report non-sensical numbers without further elaboration.

While it is true that corruption is Russia's biggest problem, the numbers quoted make no sense. I know people on both sides of the coin- small and large businessmen, tech entrepreneurs and high ranking FSB/military officials, so I know a little bit about what's happening.

edit: Another piece of the article that screams of embellishment- "small flat"- no Russian businessman that owns a 300+ employee enterprise would be living in a "small flat."
You really don't care if someone has a conceptual understanding of UI/UX? I guess that's fine if you're not doing anything unique. But if you are, how is your designer going to be able to think through the unique design problems posed by your product?

I mean - take Mint, which has been widely praised for its design. Would a designer have been able to produce it by cobbling together half-understood components from other sites?

I'd really like to hear more about why you don't think a designer needs to be able to understand what design is. I'm curious about how you think he'd even be able to successfully emulate other sites if he doesn't understand what to emulate and why.

I'm the software development director here at Ergotron. We appreciate your feedback and I will forward this to product development. It will help us improve our product. About the study, we supplied the product used in the study, but it was conducted by Health Partners Journey Well and we have no input on the results. BTW, the detailed results and methodology haven't been released by Health Parters Journey Well yet. I am told they will release those details but we don't know when.
Not knowing the details, it becomes difficult to analyze fully and fairly.

Still, if you get a request in writing, from a superior, which would exculpate you from possible negligence for allegedly improperly divulging information, if that's what he truly believed, that should have alleviated the issue.

Instead, from the outside, at least, it seemed as if he was unreasonably steadfast in his stance, despite pleas from the mayor (pre-jailhouse visit). It was as though he thought his interpretation of policy superseded the authority of the people or office who/which set out the policy.

As I recall the events, it was almost as though he became a prisoner of his own doing. Once he made a stance, it become very difficult for him to back down. As if saving face was a very important aspect of the ordeal. Of course, that's just my personal projection, perhaps.

Four years and 1.5 million is too harsh, in my view. Yet, he did deserve some punishment for his actions.

Windows 1.0: Still playing Reversi after all these years
25 years after it came out, it's still possible to run Windows 1.0 in a virtual machine. While you can't connect to the Internet, you can play Reversi and see the first version of Notepad - which is pretty similar to the one in Windows 7. Here's a look at the first version of Windows.

And note that there is a pattern to it. Just like in the GeoHotz case it's their aggressive DRM which gets them in trouble:

"So why aren't theater personnel simply removing the 3-D lenses? The answer is that it takes time, it costs money, and it requires technical know-how above the level of the average multiplex employee. [...] issues with the Sonys are more than mechanical. Opening the projector alone involves security clearances and Internet passwords, 'and if you don't do it right, the machine will shut down on you.'".
He refused to hand it over to anyone except the mayor due to his interpretation of the rules he was under. Had the mayor showed up in 5 minutes, he would only have held them for 5 minutes.

He claims his ethics prevented him from doing anything other than exactly what he did. And if he really felt that only the Mayor could be trusted with the password, he was honor-bound to hand them only to him.

The entire system not only allowed him to get into this situation, but it practically forced it on him thanks to budget cuts and ridiculous decisions. Not that he was complaining at the time.

It will serve as a good reminder as to why you should not only act ethically, but demand that your bosses act ethically as well. It was unconscionable that they let a single person have this much power over their network. Had he died, they would have had a hard time getting that password back.

actually, it hurts consumers, alot. without cookies, we won't have google analytics, or any of the major analytics packages. we therefore wouldn't know about things like screen resolutions, etc. so we'd have to design to the lowest common denominator possible, because we wouldnt know that only 1% of visitors have 800x600 screens now.

we also wouldnt be able to track conversion goals, which you seem to think is some kind of profiteering, but it's not just for ecommerce checkouts used in tutorials. for example i can use it to find out where people are hitting snags adding events to a community events calendar which i wouldnt consider a corporate special interest at all.

and what do we do about frameworks that automatically set a session cookie? they arn't just used on corporate websites.

also, i think you'll find that most corporate special interests try to minimize the numer of cookies set anyway, because when you compound a few bytes of cookies saved over a million visits, it's a large savings on bandwidth bills. not so much for cheaply developed local sites for non-profits and community groups.
agree with you 100%. My favorite example of the Western media's clear bias comes from the WSJ- early in Putin's presidency they wrote an editorial calling on him to take down oligarchs and praising his leadership style. A few years later, the same editorial section called his use of the word "oligarch" an anti-semitic slur and defended the very people they encouraged him to confront years earlier.

Russia is far from a perfect place, but that doesn't mean we should support far from perfect media coverage of it.

The google/doubleclick faction is being demonized somewhat by this. This will affect pretty much every company that has any sort of web presence beyond a static 'hello world' page.

Perhaps this will be a short term boon for freelancers to get to revisit existing sites and make them 'compliant' (a mini y2k all over again) but almost any interesting feature or functionality someone would produce is going to use tracking/cookies of some sort, both to provide value to the company and to the end user (collectively, "the public").

And yeah, I guess many of us feel 'entitled' to keep using something which we've been using as a global standard for the past 15+ years.

Stupidity is not a problem that can be solved through technology.

My reaction is: Never say Never.

However, if you are going to try and solve stupidity through technological or scientific means, beware. A half-baked understanding of science can be a dangerous thing.

Example: At Enron, the policy was to fire those who evaluated in the bottom 10% of the company. Jeffrey Skilling thought he was using the miraculous power of evolution to create a company of super-employees. What he actually did was to create a company of those skilled at gaming the system.

This was like another attempt to evolve chickens to be super egg-layers. Instead of increasing the egg-laying of the whole population, only the egg laying of the dominant females was increased and overall productivity was decreased.

Half life isn't a steady rate; it's exponential gradual decay. For example, if the element yahelium had a half-life of a year, it would degrade by 1/2 every year. So, the degradation during the first year would be twice the degradation of the second year. That's not linear.
