I've seen jQuery code. It doesn't do anything particularly useful for me.

It solves problems I don't have. I don't need to lookup elements in the dom, because I put them there. I already know where they are.

I don't need a slow .bind() method - I know how to write closures.

Look at one of the top news items - jQuery plugin 'behavior'. It just doesn't make any sense.

Look at some of the source code. For example .addClass(). It's the most general you could imagine - can take a list of classes, or a function. Yet I'm betting most of the time it's being called with a single class to add. There's a lot of wasted checks and effort in there. It's checking the type, it's splitting the string on " ", it's checking to see the class isn't already listed etc etc

Also everything is assuming it's operating on a list of elements - cue wasteful for loops when they're not needed.

So, when you do the seemingly simple

$('#myelement').addClass("foo");

it'll be cycling through the array of elements of length 1, splitting 'foo' on spaces, checking if 'foo' is a function, etc etc etc etc

Those are precious wasted cycles. And for what? so you can write:

$('#myelement').addClass("foo");

instead of:

// I already have a js ref to myElement thanks,
// and know myElement doesn't already have 'foo' in className
myElement.className+=" foo";

</rant>
Exactly. I would never pretend my code would run on anything less than IE6 or any brand of ancient Netscape. I'd love to know which browsers shipping today fail on:

window.blah === undefined

and require the more verbose equivalent I've seen pushed on c.l.j:

typeof window.blah === "undefined"

There's simply no market left for this sort of paleo-Javascript.
I will give this a try next time I need to do something like this. This plugin can nicely encapsulate UI elements. Keep up the good work.

Because Bezos never thought of Amazon as (only) an online bookstore. And Amazon has not been just an online bookstore for a very long time.
Perhaps iPhone users accept the limitations because the stuff it does actually do works so well for them?

This explanation, however, doesn't provide a good headline, so obviously isn't plausible.
Um, genius? You're suffering from hyperbolism.

It's technically impressive what they've done with there infrastructure from both a engineering and business/management perspective. But the idea is just time-shared computing which has been reimplemented a few times since the first companies offered compute time on their mainframes.
Most places in the world, they would all be tried for murder. And the fact that noone talks about who did it, IS conspiracy.

You can say everything about Italy, but not that our juridical system is broken in this way: it's much better than USA system in preventing innocent people from going to jail. There are three levels of giudice, and every level can only give you a penalty <= the previous one, and if there aren't many strong proofs it's likely you will not get marked as guilty. Also there is no such "popular jury", it's all made by professional people. We are mostly an irrelevant nation lately, but 2500 years of history of our juridical system are still in action.

But it isn't just that it's "small in quantity" that means that there is a problem. Amanda was a housemate, it would be incredible if her DNA couldn't be found in her housemate's room. The simplest explanation for Amanda's DNA being in the room is that she had previously spent some time there talking to Meredith.

To put this another way, have a think about where you would expect your own DNA to show up. At home, at your partner's appartment, at the office, at the cafe around the corner from the office, in your car, in your partner's car, at your best friend's home, your best friend's car. If a murder ever took place in one of these locations, how would you feel about the presence of your DNA being used to implicate you in the murder?

Well, we've got a facebook clone here (vk.com) where the profile is open by default and the growth rate is not worse than of the Facebook. (Taking into account the language of the network).
So I think that the growth of the Facebook has nothing to do with the privacy settings.
nice. I don't 100% understand it or how you would use it and why you would use it and not just write jquery code and structure it logically,... but then again I'm constantly finding my jquery code to slowly becoming big and using global variables and stuff to encapsulte objects' behavior... but unfortunately, I don't really understand this enough...

So because it makes a bad headline, it obviously is? It's worth investigating why, in such a feature-driven industry, a product with good marketing but so lacking in features is so popular. We've established that iPhones are locked to a carrier that has the worst customer service ratings in the industry, and that it can't do basic things other smartphones do, like multitask. Yet, it's the gadget to have and continues to fly off the shelves years after its release. I think that's pretty interesting, and simply saying "yeah, it's just really good at making those phone calls" doesn't cut it (considering a 30% drop call rate is considered OK, saying it's really good at making calls would be a stretch).

Listen, I've recommended friends and family of mine get iPhones, and I'm typing this on a Mac. But the best thing you can do for companies you like is call them on their crap. And a lack of basic chat functionality on the iPhone is a sad state of affairs, and no one really seems to talk about it. Apple does some stuff wrong, but they tend to cover it up through marketing. My wife, who used to use an iPhone, just pointed out to me as I was typing this that iPhones are a status symbol, and many people buy them more because they are iPhones than out of any real analysis of the features. Once bought, people want to validate their own decisions, so they'll defend the inferior product. Such is the power of marketing.
Nice idea. But keep in mind that this is Italy -- nothing should ever be taken seriously coming from there. I mean it.
The good side of David Mark: I have read plenty of his stuff on comp.lang.javascript over some time, and my own JavaScript is good enough to tell that his understanding is deep and his code intelligent and thorough. I would say his knowledge of the DOM and how to code for it is significantly deeper than John Resig's, lending weight to his criticisms. He has been working on Dojo and I am certain his input will improve it significantly.

The bad side: he consistently antagonises people, has what seems to be a personal vendetta against jQuery and declines to publish useful, constructive critiques, instead posting ill-formatted, snide rants dressed up as code reviews on comp.lang.javascript. His behaviour towards John Resig has resulted in Resig claiming to have turned his back entirely on comp.lang.javascript, which is great shame because I think there is a lot he could learn there to improve jQuery. If David Mark's attacks are turning people away from comp.lang.javascript, then that is unfortunate because he is by no means the only expert on there and others experts on there will have less of an audience for their insightful posts.

Writing changes the writer more than reading changes the reader.
For that specific case, the more verbose version is definitely better, since the undefined property of the global object can be altered. For example, this silently redefines it for the whole page:

if (undefined = someVar) {...}

The typeof check cannot be broken in this way.

If you want to talk about history, you have to refer to historical sources, and those sources don't show that people in what is now called China or what is now called India thought about these issues any earlier than people in what is now called Greece. We have no idea whether or not there even were "early Taoist exercises" (and it would be debatable to call anything "Taoist" before the life of Lao Tzu,

http://en.wikipedia.org/wiki/Laozi

who may not even be a historical person) unless we can find mention of "Tao" and mention of that thing associated in a historical source.
I didn't suggest the opposite. Bad headlines do not equal truth.

The iPhone appears to be driven by a vision of making certain things easy and safe, at the expense of everything else. Since these things are desirable, whether technical or marketing driven, users are willing to live with the decisions made by Apple.

This is not defending any of the "crap", this is recognising that the choices made are very successful.
Its origins as a bookstore are incidental. Amazon started out as an online bookstore because Bezos knew the web (or web commerce, I'm not sure which) was growing at 2300% a year and wanted to get in on it in the best possible area. That area turned out to be books, because they were cheap to ship; required catalogs too large to print, but easy to browse through online; and had a large profit margin. It then expanded from there. It was and always will be about general online commerce.

Just composing in the head is a nice first step, but merely thinking about something makes it easy to gloss over flaws in your thinking that you have to face when wrting something down (if you do non-stream-of-consciousness writing).

On the other hand you have to think about things only tangentially related to the actual problem you are writing about like style, grammer and finding the right words.

So there are advantages and disadvantages to actually writing stuff down.

>>It's worth investigating why, in such a feature-driven industry, a product with good marketing but so lacking in features is so popular.

The arguably best UI around is a killer feature. That is something which generates love. Great usability makes the UI just "disappear", you don't think about it.

Just look at which phone users really manage to use them for data traffic (and the carriers' trouble with that).

This isn't unique to Apple. I buy pens (Pilot G-tec C4) which break really easily. That is not really smart, but their thin writing is a killer feature for me. I buy them a dozen at a time without even cursing.

Now that I actually try it, I think you're right.

I had assumed that the browser would load the external JavaScript, parse it and execute the code. I understood that the code in the page (the src built by the coder) was not going to be compromised. I should have realized that the browser would treat data loaded through an img src tag differently than it would data loaded through a script src tag.

Some versions of IE can be fooled into executing JavaScript contained in an image file, but the image has to be loaded on its own (in an iframe or a new window), so it wouldn't apply to my original comment. (http://www.splitbrain.org/blog/2007-02/12-internet_explorer_...)

This is the moment of commoditisation of computing.

I'd call it the next moment in the ongoing commoditization of computing. But everybody has a different threshold of perception. ;)
You see this a lot in the mainstream press, some journo saying "what's the point of competing to see who has the most friends" or "who cares what some random people are up to" whereas in reality, no-one who is what you call a real user even thinks like this.

It is also true however that FB wants to cater to that group as well.

I agree we need easier-to-use documentation on this stuff, but have you considered documenting what you've done yourself? I started keeping a notebook of helpful tricks back in the 90s. By the mid-90s I was publishing some of the info, and by the late 90s I had friends working with me to create articles. This was when the e-Zine was still pseudo-popular as a channel of self-publishing. We later went on to blog format, but the results are the same:

Your brain forgets little, but loses references to information it hasn't needed to use in a while. Documenting things (which includes proofreading and maybe even testing your documentation), uses repetition to solidify those references. Some people learn by repetition better than others, but even if it's just penciling apache config tips or iptables examples into a Moleskine journal, writing is often one of the best ways to memorize things.

The things I've written down are the things I remember best or at least they're the things I find easiest to come back to. It goes for the awk recipes I've jotted down, database tuning parameters, and even automotive repair tips.
I've often thought about a software package that implements achievements for completing various tasks with an office wide leaderboard >_>
I see what they are saying; but I have a different counterpoint.

I got an iPhone because it looks nice and I figured the apps would be cool. Well it looks nice but the apps, for the most part, don't do much but divert me. There are some I use - but not as frequently as I use the phone, email and calendar features.

I toyed with ditching the phone but now I cant: im totally sold on the phone functionality.. it's the best set up I've ever had.

And there I think is the hook: the iPhone really does just work as a phone. Lots of smart phones never manage that :)

(there are plenty of "wtf" moments... but they havent yet completely frustrated me - which is rarw)
I resent Zuckerberg. He got extremely lucky and is massively overrated. I wouldn't be upset if he were just a millionaire a few hundred times over; who cares about that? But he certainly doesn't deserve to be the most successful member of our generation, and hopefully someone will eclipse him in that regard.

Facebook has some exceptionally good programmers, due to its financial fortune, but the mediocrity of vision and hubris at the helm persist. Facebook has some great technologists, but the leadership couldn't make a good decision to save their lives. Luckily for them; to this point, they've never needed to.

I liked the iPhone because the features that were lacking at the time were not very important to me, and the features that were implemented are for the most part extremely well done; not because I'm some delusional fanboy.

My needs have changed a bit and so I'm using an Android phone now. But I was pretty happy with the iPhone for quite a while, despite its limitations.

From the article: 'which many reports say is a variant of HTC's HD2 phone.'

The HD2 has a 4 inch screen, I don't think anyone is saying the phone looks like a HD2. From all reports, this is simpyl the HTC Passion, distributed internally amongst Google employees the same way the Dream and Magic were. Which were (and are) also called 'Google phone' by Google employees.

In short: nothing to see here.
My philosophy on the matter is that some men make a social ritual out of getting together with their buddies to watch other men slap their bodies into each other at high rates of speed, while other men make a social ritual of going out to hear people sing of torrid love affairs in classical Italian (which they don't actually speak), and if these folks can be normal, upstanding members of the community I don't have to feel embarrassed about a bit of relaxing dragon genocide every once in a while.

Location’s Social Paradox
I find sites that hide the login form to be extremely annoying, including Twitter. Keep the login form visible at all times and don't require an extra click for your users.

LinkedIn also hides its login form on another page - it assumes you want to sign up if you land on your profile page (e.g. from a bookmark) but you're logged out.
His point is more subtle - you can do browser detection based on user agent strings, feature detect, conditional script inclusion, even css hacks which set styles that can be read from javascript. His point (such that it is) is that these are all bad ideas.

Instead of detecting which browser you are using based on which features you support, the script should check to see if the features it wants to use exist, and if so use them.

So, instead of:

var isIE = !!document.all;
function doSomething()
{
if (isIE) document.all.whatever();
}

You do:

if (document.all)
{
function doSomething()
{
document.all.whatever();
}
}

Even closer to the point, he means that these are both bad form:

var isIE = navigator.userAgent.ssubstr...;
var isIE = !!document.all;
