Its all good I definitely don't hold the place or the people to blame. I was living in Cookstown at the time traveling around meeting long lost relatives. I met more than a few good people, but also some of the worst (a few fisticuff incidents stories not appropriate for here, and being questioned as to why I had just wandered into a local pub). It just took a long time to gain peoples trust after that you where treated like royalty.

Is LinkedIn Heading for Disruption?
That sounds rather intriguing. I almost wish I hadn't de-registered from G+ during my social networking existential crisis. By the way, the people saying that you can't navigate the Google ecosystem without being prompted to join G+ at every turn, I'm finding them hard to believe as that has not been the case for this lone datum, me.
That seems like it could work pretty well as long as you can reliably detect that a browser's display is high-DPI. Can you do that? The last time I checked, it's not possible to reliably detect a high-DPI display or force the page to render at a certain DPI level - Chrome used to have a meta viewport attribute for it, but it was removed.

I'd love to see a JavaScript library that does this; I've never run across one.

I wondered this, and I suspect the title of this post used to be something different, before being changed by a mod to what it is now.
I think the main obstacle is that most companies are uber focused on mobile, and adding high resolution assets is going against that initiative. I don't know of any companies that have a Retina initiative.

I understand that there's ways to serve lower res assets to mobile devices, but many of these architectures are already set and updating them to take advantage of media queries is not high on the list of to-dos.
The article (and so far the comments here on HN) are all talking about "double resolution" but in reality it's quadruple for actual retina aseets.

a 120x90 image becomes a 240x180 and that's not 2x the pixels, that's 4x the pixels (and bytes.) It's not insignificant. There's great reasons not to bother right now:

1) On phones and tablets people are either going to be zoomed out where they can't appreciate the hi res images, or zoomed in on some text and not really looking at the image most of the time.

2) While I have an rMBP, most people don't. They're starting to get around but for now it's fine. Certainly I agree with the author's advisement to figure out a solution this year, but I disagree with his admonishing of people still putting it off right now.

3) Lots of people who DO have rMBP do NOT run the machine in pure Retina 4:1 resolution. That includes me, I run it in 1920x1200 mode. Most people don't go seem to go that high but even at 1650x1290 "bad" images are much less bad.

Basically, my point is, this isn't as big of a deal as some people make it out to be. I think it's most important for large hero areas and other images that are going to be focus points of your page. But as long as you get on it some time this year you should be fine before a significant portion of your users are thinking your site looks ghetto.
"They are trying to evoke the kind of user "

Way to obscure. It's not a indie film being analyzed in cinema class. It's a website image. It needs to not leave practically any chance for misinterpretation.
I actually thought this was a joke until about half way through. It said it great in the first four words: "It's been six months." You expect the entirety of the internet to transform in a matter of months to accommodate your latest gadget?
The author may want to fix his menu-bar before complaining about others. It's a tiny, blurry mess on my 27" Thunderbolt-Display. On a smaller retina screen it probably looks more like a smudge than text.

You can just read 'window.devicePixelRatio' using JavaScript. Retina devices will be more than one.
Why not take a look at http://www.lonelyplanet.com/ then find a couple of places you like and buy the destination guides. They're a good start. I did this when travelling around Australia and New Zealand and found the books extremely useful.
I don't own any Retina devices, and won't for the immediate future, as a not-yet-employed student.

How can I test how my webpages will look on a Retina display, without hardware? I haven't found an answer (admittedly, with only a little searching) that doesn't involve me taking the bus to the local Apple store each revision.
I would have never thought to do that, but I will admit that I've occasionally stopped for a milkshake on a long road trip for much the same reason given in the article.
I'd prefer it if I could see the possible "goals" before entering my contact information. At the moment it is the usual: no information before signup. (I didn't proceed past the contact information tab, so can't comment further).
Many comments seem to focus on traditional GET requests in which case long URLs are usually a smell. But there's a rather new requirement in the web that conflicts with limits on URL length: the use of modules for front-end JavaScript code. The best practice for modules is usually expressed as:

1) Write small modules
2) Concatenate scripts

If you try to automate module concatenation then you'll get URLs like http://example.com/combo?foo.js&bar.js&baz.js, which combined with "write small modules" can mean a long list of small modules that easily reaches 2000 characters.
If I'm looking for a high paying job, a few dollars isn't going to interest me. Your friend probably had to create a ton of code to allow for the applicant to store and eventually withdraw his few bucks. If I'm really looking for a job, how many recruiters could possibly contact me? 10-15? at $2, that's $30 at the end of the process. Seems more like a distraction from my job hunting.

It seems more like a distraction from core development (having to manage the cash accounts for applicants) and not enough money to be interesting.

I can see charging the recruiter to email people (sites like Elance do that) but that's where it should end. The money will never be interesting enough for an applicant to care and it confuses the process.
It may well be that hard-right conservatives are opposed to copyright reform. But I think you will have to agree that progressives are likewise unlikely to cover themselves in glory here, as many of the most vicious and relentless lobbyists for maximalist copyright come from progressive redoubts like Hollywood, the RIAA, and NYC media.

Can you use CSS media queries to detect the display's DPI? I haven't seen any examples of that.

You can at least detect the 'device pixel ratio', which seems to be > 1.0 for Retina devices, so that's something:

Useful Vim resources
Hey guys,
here is a list of Vim resources I found from time to time in the interwebs and it'd be great if you add yours!
Well when one coder reaches 5 000 LOC of Java in one day, even if there are a few bugs in there, it still indicates some hardcorness. I've seen my ex CTO do that and it was fascinating. Hardcore startup style: "get the feature out as soon as possible because one of our first client badly needs it".

Then, when you take a 100 KLOC codebase in Java/C+/Obj-C/whatever and trim it down to 10K LOC of some Lisp dialect, it kinda indicates some hardcoreness too.

I know it's a "false" metric, but once you take sufficiently big values, it still serves a purpose.

I don't have a retina device, so I wonder: are they not capable of rendering normal resolutions? I would have assumed that they simply render a "classic pixel" as four retina pixels? So classic web sites should still work?

Which if we're going to be honest is a hugely overhyped issue.

Note: I base this on how often I've swapped out the database for a project in the past 15 years (maybe twice?) of writing mostly database backed software.
If you have a Mac, you can use Quartz Debug to enable HiDPI mode on a non-retina screen. I wouldn't attempt that if you have anything but an iMac or large external monitor though.

Alternately, get an iPhone 4 or one of the older retina iPod touch models. I picked one up for $80 to do some testing on.

No, but they will be by devices like Lytro and the Kinect, and video camera descendants thereof. Instagram filters are just the beginning in terms of automated digital post-processing to allow semipros to shoot pro quality photos/footage. It'll take a little longer than blogs did to disrupt print, because the underlying data (sound, video, images) is more complex, but it is inevitable.
Well, I never could get it to realize my imagination. However in retrospect that could have been a good thing- I spent countless hours trying to render my imagination in plastic blocks, and it required quite a lot of creative thinking.

I think my problem is that I've never written a line of ruby in my life and as a result my mind just can't grok why they are jumping though some of the hoops they are jumping though.

I would say that Perl is roughly on par with other scripting language in terms of how concise it is. The downside is that it is more idiosyncratic, the upside is that it has better libraries. Perl has been good to me, personally, but I'm not about to try to tell a Ruby or Python developer that they have an overwhelming need to switch.

However the advice about knowing your tools applies to proofs, programming, cooking, mechanical engineering...
I think establishment liberals and conservatives have all (correctly) come to the conclusion that might does not make right, and the fact that it has become absurdly easy to violate copyrights for the noble cause of "I am entitled to watch _Resident Evil: Retribution_ on any terms I like" does not somehow obsolete copyright.

Every time my fellow nerds see fit to inform me of how outmoded copyrights and rights-supported business models are in the era of the Internet and BitTorrent, I think of how outmoded their business models are, built as they all are on the idea that anyone in the world couldn't pop a shell on them at any moment and wipe their databases clean.

But then I remember that they've also stuck up for DDOS attacks as "the digital equivalent of a sit-in", and I give up.

And slightly less retro, if your on mitt challenge make it 3d
Apple renders a classic pixel as four retina pixels, but they don't apply any filtering, so it makes graphics (particularly text with subpixel antialiasing enabled) look rather awful. If they did filtering it'd look much better, but you can probably imagine the economic incentives not to do that.
less retro more fun here https://www.youtube.com/watch?v=2W6TaNaV6W4
The big challenge for something like this is being your "default" mail and IM solution, vs. something you just use for one-off secure messages. My experience is that if you go for the latter, no one actually uses it. $5/mo is probably the wrong price even for individuals -- I'd go with free (on the low end) or $10-15/mo.

The big thing would be interoperability with everyone else not already using the service (easy for email, harder for IM), and then providing network-effects benefits if both sides of a conversation are subscribers.

The business/group space is a lot more interesting, I think. $500/yr for a few secure mailboxes (5? 10?) would be less work for you than a few $5/mo individual clients.
Regarding the "euphemism treadmill": sometimes it is necessary to coin a new euphemism. For example, if the common usage of a word is different from its original meaning. "Homosexual" was the name of a psychological disorder, "moron", "retard", and "idiot" were all clinical definitions of mental handicap.

Times change, words continuously change meaning. Use the words that your audience understands, not the ones that your audience understood last week or one hundred years ago.
Those are simply nerves that run in the eye, everyone has them.
"Sucking at webdesign". Today we'll discuss how to turn on antialiasing, that is so glaringly missing from the authors blog:

1) It sounds like companies are hand picked. On the other side: How do you filter for great developers? I'm sure you can't assume every prospective employee signup is a top-tier developer. Do you have some algorithmic, human, or other process?

It is a combination of all of the above. All companies are screened so we know what makes them unique and what type of developers excel there. We do the same for the developers. Everyone is happy only when we make appropriate matches...since we are developers, we think we can do this better then anyone else.

2) As someone about to graduate and transition to a PHD program after the summer, I'm looking at technically challenging summer internships. I'm sure there are other prospective interns. Do you have any plans to support matching summer internships?

Yes, right now we pick that up from your goals and by looking at your background. At times we may reach out for more information so we can understand your unique situation.

3) Assuming a github profile is the only "resume" your site accepts (implied by another comment here), where do developers list journal and conference publications? (Apologies in advance if this assumption is wrong -- I haven't signed up due to reasons mentioned in question #2.)

You can supply your GitHub profile and/or Resume...ideally both. We'll look at improving the sign up process though. We just wanted to make it super simple and easy for developers to start.

Oh, snap. I just got ASCII-arted by tptacek.

You know what? I'm going to do this, just so I can settle this once and for all and be right on the Internet. I'll throw up a crap product, work on it like five hours a week, and we'll see how far in the hole I am from hosting costs.

Incidentally, it's the second part ("Carefully study how best to present your offering to your target market") that I believe to be tremendously difficult and that I don't believe I will have much chance at. From where I'm standing, one of three things happens:

1. You get lucky and happen to be very good this.

2. You get lucky and happen on the right approach without actually being good at this in general.

3. Your product earns back nearly 10% of its expenses.

Your argument would carry more weight if your analogy were better. But the fact is that social networks are what Dijkstra would have called a "radical novelty":

"The usual way in which we plan today for tomorrow is in yesterday's vocabulary. We do so, because we try to get away with the concepts we are familiar with and that have acquired their meanings in our past experience. Of course, the words and the concepts don't quite fit because our future differs from our past, but then we stretch them a little bit.... It is the most common way of trying to cope with novelty: by means of metaphors and analogies we try to link the new to the old, the novel to the familiar. Under sufficiently slow and gradual change, it works reasonably well; in the case of a sharp discontinuity, however, the method breaks down: though we may glorify it with the name 'common sense', our past experience is no longer relevant, the analogies become too shallow, and the metaphors become more misleading than illuminating. This is the situation that is characteristic for the 'radical' novelty." (EWD 1036)

Hammers don't care if we use them or don't. There isn't one big Hammer.com that produces all of them. Hammers are not constantly acquiring new features. Hammers aren't useful or not on the basis of how many other people use them. Hammers do not even have significant overlap with other tools. Hammer.com doesn't need to convince anyone to try hammers. Companies that make hammers want you to buy their brand, but they don't bother with trying to convince people they need them.

Look at all the differences from social networks. Unlike a hammer, if nobody else is using LinkedIn, it's not useful to you anymore either. If everybody quits using LinkedIn but you, LinkedIn won't have any revenue, even though you're not paying to use the service. If everybody quit using hammers for stupid reasons, there wouldn't be anything stopping you from using them; in fact, any hammers you already own would continue to work. LinkedIn could just vanish despite your protests.

LinkedIn is pretty unlike a hammer, so I don't find your argument holds all that much water. It's a social network, so it's of interest and on-topic here when people decide to leave. It's interesting, because many people here are building their own startups and many of them are social networks. They survive or die on being used. If there were great insights in this article about how to retain users, it would be especially interesting, but knowing that there is a general malaise about this one is still information, and the article is still well-written and I still feel I got my nickel's worth from it.

Blogs "disrupt" print by providing pithier summaries of content that costs millions of dollars spent on real reporters and their expenses to generate. Do you think written journalism is better in 2012, or way, way, way worse? I'm going with "worse".

But I'm not here to promote the status quo ante. I'm just saying that the idea that progress for the tech industry as an inevitable and intrinsic good is a little suspect.
What is the use case for concatenating scripts on request rather than as a build step?
Can you articulate how any of the numbers you're mentioning have anything to do with their ability to pay for capacity upgrades? Earnings are what's left after they make their capital investments. And after they make all the investments they deem necessary, they're still posting large, stable, recurring profits.

Moreover, when a corporation is simultaneously holding debt and issuing dividends, the reason it continues to hold the debt is not because it needs to remain "in debt" to continue its operations. Barring incompetence, it's almost always either because the rate it's paying on the debt is below the market rate of return and so paying the debt has a negative relative value, or because holding debt has some sort of tax or business advantage for the company.

And bringing in Google is just a complete non-sequitur. AT&T can't afford to pay for upgrades because Google has a lot of money? Nonsense.

Custom 404 page under usability? hmm.

I'm sure just about anyone who has used the web for any length of time has hit the standard apache "Not found" page hundreds of times now and pretty much knows what it means.

Custom 404 pages of often quite confusing as they will try to be clever and redirect you to other content that may be interesting. Sometimes these aren't clear and give the impression that the link was not broken and that this is where the site designer intended you to go which leaves you looking around the page for the content you thought you were going to get.
