I actually believe that this will be our future. Imagine having your kids grow up in a world where you're learning with children around the world with the best education possible. The cost of this school would be very low or even free.

The cost of tuition and the continuation of the deterioration of the American school system should raise giant red flags for anyone who's concerned about our future as a society. Anyone with kids should be concerned. Luckily the internet is not all about social networks. There's still an amazing repository of information up for the grabs.

This is already happening informally with wikipedia and other wikis out there. As a developer (after basic comp sci courses) a large portion of my education is through online forums. If I can hold on to a steady job with information found on the net, then something is indeed working.

I'm actually developing an art education site (www.artjutsu.com) and would love to see how far it goes. I'm considering submitting to ycombinator, but I'm the only one on this project. I see that they don't really like to fund a project with only one member.
Photoshop Tutorial: Create A Wooden Photo Frame.
Hi friends. We are back with another awesome tutorial. Today in this Photoshop Tutorial, we will create a beautiful wooden photo frame from scratch.
Early in your career, trading salary for experience is a smart move. In my case, I turned down a Google offer to work at a startup after college (taking a 15%-30% pay cut) and my equity ended up being worth less than I paid to exercise it. But, in the two years that I was there, I learned way more than I would have at Google, and got a much bigger network, both of which helped immensely when I interviewed for my next position.

I agree, working for peanuts is dumb. But 20%-40% less than what Google offers is hardly poverty -- it's still much more than what most non-engineers make out of college.

> Completely hidden "edge of screen" elements are very nice but only work if you know they're there already. What do you do when you don't? You're boggled, and either you try hunting the interface for active areas (looking for pointer changes, old-school adventure games style) or you give up and go back to something you can use at a glance.

Is this really how we expect to progress as an industry? Basically make no meaningful changes so that we never expect our users to learn anything new? Do we have that little faith in our users?

How obvious is it to a new iOS user that they need to press an icon on the Home screen until the icons go wiggly in order to re-arrange them? I'd argue that this is pretty non-obvious, yet every iOS user has learned this action, despite there being no "active areas" that reveal this behavior.

Actually, I think it isn't even reluctance to learn something new--people aren't even aware of Linux as an option, and if they are they think it's only for geeks. I bet if you could go out and get a $500-800 laptop at places like Staples, more normal people would be using Linux.
>> Linux won't be ready until you can download a file from the Internet, run it, and install it just with a couple clicks (and not "you need to set the 'exectuable' flag!" error).

I probably agree with a lot of your other assertions, but this seems to miss one of the central purposes of a repository-based package manager system.

Security may not be a very high priority at this moment for novice users of Linux distributions, but it will swiftly become one as Ubuntu continues to gain popularity. The old paradigm you're describing - download a solitary binary, double-click to install it across the system - is a huge security hole that Microsoft (for instance) has spent and will spend billions of dollars to patch around; the vast majority of exploits on Windows machines seem to be based on the fact that an unsuspecting user can easily download and run code that is swiftly given root access to their whole machine.

The repository system - a system where the set of programs available for easy download and installation is carefully managed and maintained - is an idea that was decades ahead of its time, and it's only just now that repositories (and their children, "app stores") are becoming a fact of life on lots of platforms. App stores are useful because they make things easier for users, but they're also extremely beneficial from a security standpoint. They also offer a simple, obvious, secure way for individual applications to be updated and patched when necessary.

tl;dr - Novice users should be strongly discouraged from downloading and installing standalone programs. This is not a feature of Windows; it's a bug. Yes, there are lots of essential Linux programs that are not available easily on the Ubuntu Software Center. The solution to that problem is to improve the repositories by adding them. Making it easier for novice users to run downloaded code blindly would be a mistake.
So you are neatly packaging your knowledge, publishing it and marketing it (at least here and on reddit, not the smallest websites, possibly elsewhere) but somehow it's still a "personal document" and your "best practices" shouldn't be followed?

As soon as you publish your document and market it the context of your statements changes. A lot. Think about all the *-killers that pop up every single day: the Internet loves to bash them when they fail.

It takes toll psychologically. There's that nagging feeling that "had they listen to me, we wouldn't fail this bad" for a while depending on how slow/fast you can move on.

The positive part of working at a failing start-up is about opening your eyes that start-up isn't as glamour as what people perceive it to be. It makes you not wanting to work for a start-up ever again unless it is yours. So I'm not saying it kills your entrepreneurial spirit, but it does kill your youth-risk-taking-high-flying mind.
Because `.nav li a{}` is overly specific; that’s my whole point.

There was and still is no realistic way for Google to switch to WebM.

YouTube, no. Chrome, obviously YES. Firefox and Opera did and still do it. Their failure to use Chrome to push WebM means they killed off their own format. Tells you something about their priorities.

I get that moving forward means breaking existing paradigms. I'm happy that MS is trying Metro (not so happy with the horribly anti-user policies surrounding Metro, but I digress), and don't mind that it's a change. That said, they need to leave some kind of path for existing users to map concepts onto the new UI. A great example of this, I think, is in Gnome Shell, where the "Activities" hotcorner is clearly labelled, and fills the same UI role as the "Applications" menu in previous versions of Gnome. A user moving from Gnome 2 would likely try to click Activities, and while they may be surprised at the overlay that results, would still find all their applications in one place there. From the looks of it, Windows 8 provides no such path for users to attach existing intuition to. Change is fine, but it has to be done well.
Great points and I'm definitely not just going to jump in without doing some research on business, however I also don't want to jeopardise my business by making mistakes on forms, etc.

Specifically, what justifies this is that the parameter is optimized via cross-validation, so within the space that we're optimizing over, we know that we're picking a good parameter. If it's not equal to 1, then it turns out that the "rigorous" probabilistic model was missing something that turned out to be useful.

In this case, it's that the probabilistic model only incorporates naively measured probabilities, and does not account for the error in those measured values. This is rather tricky to do right - you need to know a lot about the true prior distributions as well as the error distributions in order to account for it, and generally we don't have enough information to do this effectively.

So we "cheat", and just use the probabilistic model as a starting point to launch an optimization against.

This is great advice. You should understand what's going on, what your company needs to file and to who. However, get your accountant to do it for you, things such as Corporation Tax / VAT returns are complicated, and you will get no sympathy from HMRC if you screw up.

http://en.wikipedia.org/wiki/John_E._Sarno

There is a lot to say on this but I don't have the time. Two things are important; to say that RSI is psychosomatic does not mean its not real or "just in your head". And I reject Dr. Sarno's "repressed rage" theory and think that RSI can just be a positive feedback loop between the perception and creation of pain. In your description of your symptoms notice how focussed you are on your body and your perception of pain, I think that is the trap.

In any event, his methods will work regardless of whether you accept his explanation of the cause. He's got a couple of books out that explain how it works so no expensive treatments. There are websites of people who have successfully recover from RSI and chronic back pain using his techniques.

I see no Post-PC world, only an admission that Dell's profit margins will never return to 1990's levels.)

The "Post PC" world doesn't remotely mean PCs will disappear. We've been in the "Post Mainframe" world for 30+ years, yet Big Blue still makes a lot of money on super computers.

When people talk about "Post PC", they are referring to where the majority of dollars will be spent and how the average person will interact with computers. We are still learning how to make that interaction really effective for producing content, so we haven't completely left the PC world, but within a couple years, we will be there.

One other thing that will be a hallmark of this transition will be ubiquity of computing. In the PC world, there were one or two general-purpose computers in a home. In the Post PC, there will be dozens. And even more special-purpose devices.

Up to today, Post PC products have been mostly used for consumption. This is a side effect of two things: most computers are used for consumption and, as I mentioned earlier, the interactions for creation are still a work in progress. But progress is happening. I've used my iPad to author business presentations from scratch, to do mockups for my web product and to author blog posts.

There are a lot of advantage to having a device that works more naturally with my creative energies. If I'm relaxing on the couch, I can continue to do so. The laptop forces me into a different mindset.

But, yes, PCs will certainly continue to be around and useful for a good number of people.

Note how it's a conditional - drug possession OR trafficking OR (unrelated) non violent.

If we release all drug possession, what ratio would it be compared to W. Europe? Would the highest still be orders of magnitude higher?

--

I'm saying ending the War on Drugs would release drug possession AND traffickers AND a large percentage of violent crime would just not happen.

This is just one example. Criminal justice isn't my thing, but then there are a myriad things you can do to prevent recidivism. For instance, the barrier to participate in the regular economy as a convicted felon is absurdly high and, although I haven't statistics to quote for you, I would bet is a huge part of the reason so many people revert to crime (like, oh I don't know, dealing drugs again).

It's about the economics! Incentives matter! Etc.

> I'm convinced that watching TV is harmful to a child's intellectual development. (And there's an established body of evidence to support that.)

There might be evidence that early exposure to television, before the child's neurological development is ready to deal with it, is harmful. But I'm not aware of "an established body of evidence" proving that TV is harmful. Do you have sources? I'm very interested in seeing such sources, as I used to be under the impression that TV is harmful, but I am now convinced otherwise.

Be careful ignoring the scientific method here. You are equating a fear of bad side effects from TV with bad side effects with iPad use. Fear is not the scientific method.

There are many dimensions to consider when evaluating harm. For example, in early childhood development, the child desperately wants to imitate the adult (or role model), and will suffer certain side effects (e.g., problems with self confidence) if forbidden to imitate. Thus even if there is harm in using the iPad, there could easily be more harm in forbidding its use (but this can easily be remedied by never allowing the child to see the adult using the iPad).

I urge you to be careful about following any lines of parenting that mold the child (e.g., the child should be outside playing ball, not inside doing X). I see parents force their kids to conform with preset ideas of how a child should be, ignoring how early child development works, and thus cause pscyhological harm (e.g., internalization of fear of the parent). An analogy would be the parent teaching the child how to walk by grabbing the kid's legs and moving them in micro-adjustments; the kid will end up with poor motor control.
This is more of tweak of naive Bayes than Bayes' theorem and I suspect he is being a bit tongue in cheek and not letting on whats behind the tweak.

I am sure you have heard that naive Bayes makes gratuitous assumptions of independence. What is not mentioned as often is that it also assumes the document has been generated by a memory-less process.

So if I were to generate a document according to the model assumed by naive Bayes, and I want to decide if I should concatenate another "the" in the document, then I dont need to keep track of how many "the"s that I have already added to the document. As a result the probability of multiple occurrence n_i of a word i goes down exponentially, like this

P(n_i) = p_i^n_i.

Many words do not behave like this. Their probability do not go down monotonically from the start, rather, for words like "the" their probabilities (conditioned on their history) climb initially and then go down.

Naive Bayes works surprisingly well in spite of their grossly violated assumptions. There are many explanations for that. However, we usually forget that to make NB work, we have to throw away "stop-words". Among them are those exact "memory-full" words that violate NB's assumptions.

Lets get back to word frequencies: A model that fits word frequencies quite well is the power law. http://en.wikipedia.org/wiki/Power_law They look like this

P(n_i) \propto n_i^c

where c is a constant for that word id i. For English, c usually lies in the ball park of -1.5 to -2.1

The tweak that Norvig mentions is not an exact match for power law assumptions but it comes very close. Its using a power law assumption but with sub-optimal parameters. In fact using the power law assumption and with their parameters estimated from the data you could get an even better classifier. Though be careful of the industry of seeing power laws everywhere. Log normal distributions can look deceptively similar to a power law and is more appropriate on many such occasions.

Yeah Naive Bayes has a bad assumption of independence, but there is no reason that they have to be memory-less too and that is partly what the tweak fixes, and the theorem isn't really being violated.

His advice for using 'short selectors' for performance is just plain incorrect.

http://code.google.com/speed/page-speed/docs/rendering.html
is a great page describing CSS performance.

Selectors like '.nav a' would not be allowed at all as a part of my team's CSS best practices, as it is a descendant selector that uses a tag as the key. (On the other hand, most sites, expecially non-dynamic sites, don't need to optimize CSS at all, as there are usually other things which are the bottleneck)
