Great post from @JoshuaBixby checking if rules from my first book still apply. Do they? http://t.co/Z4tHANvS

Looks like a good example of how to do it.

Hacker News YC: Why CSS Testing Could Be Huge http://t.co/ASB6ASEo

"Actually that’s the number one “new model” that the Digerati suggest. Sell T-shirts at your shows to make money! This despite the fact it’s not new. Bands have been selling t-shirts at live shows since the early 1970s. Recording albums to sell a few t-shirts is a terrible way to make money. Thanks for the advice but no thanks. Plus t-shirts are just as bootlegable as music."

There's a lot wrong with this article but there's also a lot right with it, too.

"Why performance matters for e-commerce"

"A grunt task to automate moving files to/from Amazon S3."

"Now that we’re seeing wide-scale adoption of front-end optimization best practices, misapplication of these best practices could be delivering “false positives” — sites that test well but look bad for real users."

"Every development project, no matter how complex, should have a repeatable, predictable (preferably scripted) new developer project bootstrap."

"Style guides (or pattern libraries) are the perfect place to start a website build and a modular base. They bridge the gap between design and development. They’re somewhat similar to a traditional brand guidelines but contain less fluff & nonsense and 100% practical code examples."

"CSS has an underlying design and when you work with it, with the natural flow of how CSS is meant to be used, you will find you have a lot less bugs."

"We are living in a world of accelerating addictiveness and increasingly I think the only way (likely lonely, squirming, and eccentric as Paul alludes) we'll "get things done" is the continuous directed practice and improvement of willpower, productivity, flow, and exercising thereof."

"Loosely, the single responsibility principle states that every module or chunk of code (a function etc) should do one job well and one job only. The benefits of this are mainly in the way of maintainability and extensibility. If we don’t adhere to the SRP then we are likely to end up with code which does more than it should, this means that altering one part of that code could negatively impact a seemingly unrelated part of the same snippet."

Must remember. "Which is better: mylogo.1.2.gif or mylogo.gif?v=1.2? To gain the benefit of caching by popular proxies, avoid revving with a querystring and instead rev the filename itself."

@getify @smashingmag About pixels vs ems in media-queries: http://t.co/YqcC8tpw #fronttrends Spoiler: use ems!

"Ditch media="print" if you have one! (Hey why isn't this a yslow/pagespeed rule?). Ditch it because in the best case scenario it will only block onload. In the worst case it will block initial paint, onload and DOMContentLoaded. Sitting in front of a white page with no feedback is the worst possible user experience."

"Now that we have a great choice of fonts that can be used on websites, it becomes clear that the translation of a design into pixels is not something that happens naturally or consistently. OS makers apply different strategies to render how typefaces are displayed, and these have evolved greatly over time (and still continue to do so). As we now look closer at fonts on screen more than ever before, we realize that the rendering of these glyphs can differ significantly between systems and font formats. What’s more, it has become clear that even well-designed fonts may not look right on Windows if they are missing one crucial added ingredient: hinting."

"Real-world connection simulator and bandwidth limiter." Very handy.

Our new ssg mix is a special live set from Ukkonen, who we think represents a bright, strange future of techno: http://t.co/CpPr7khS

"The idea that a 10-person company of 20-somethings in Mesquite, Texas, could get its software on more computers than the largest software company in the world told him that something fundamental had changed about the nature of productivity [...] The success of Doom made it obvious that this was no longer the case. There was now little value in doing the same thing even twice; almost all the value was in performing a valuable creative act for the first time."

"I think we’re seeing the emphasis shift from valuing trivia to valuing tools. There’s a new set of baseline skills required in order to be successful as a front-end developer, and developers who don’t meet this baseline are going to start feeling more and more left behind as those who are sharing their knowledge start to assume that certain things go without saying."

Setting up a LAMP stack on Virtualbox.

"The collaboration on apps like GitHub should be exactly what happens on blog posts. The readers posting comments should read the entire article, and should offer constructive, polite criticism and suggestions, without any unnecessary negativity."

"Let that picture sink in: at 180KB of JS on average, script isn’t some helper that gives meaning to pages in the breech, it is the meaning of the page. Dress it up all you like, but that’s where this is going."

Marketing in a not-too-horrible way

"Even more than anachronism, a core theme of Mad Men is the lost art of personal reserve, self-effacement, and mystery. When Don Draper says, "Tell Jimmy I need to talk to him" in season 2 instead of "I have to talk to him," it hits a slightly more narcissistic, self-revealing note than it should. A baby boomer might set up a business meeting by invoking his personal needs; but a member of the "silent generation"—particularly one living a double life like Draper—doesn't talk about himself quite so readily."

"With the exception of Nairobi — insert joke here about Kenyans crushing everyone at the New York City Marathon — the fastest walking cities were from wealthy nations. The statistical analysis confirmed this general perception: two of the three strongest social predictors of walking speed were a country's G.D.P. and its purchasing power parity (the other was its individualism). Indeed, when Levine considered all his "pace of life" metrics, he found that pace of life was swifter in "economically productive countries" like Western Europe and Japan than in undeveloped countries."

"I realise that in pointing out that advertising is fundamentally shit, I’m not being very helpful and I’m not exactly offering much in the way of solutions or alternatives. But I rail against the idea that we need to accept intrusive online advertising just because “that’s the way things have always been.” There are many constructs—advertising, copyright—that we treat as if they are immutable laws of nature when in fact they may be outmoded business concepts more suited to the last century (if they ever really worked at all)."

Great review of @font-face performance by Dave Artz: http://t.co/CqPOUaBY

"Frictionless sharing has the same drawback as “effortless poetry”: its final products are often intolerable. It’s one thing to find an interesting article and choose to share it with friends. It’s quite another to inundate your friends with everything that passes through your browser or your app, hoping that they will pick something interesting along the way."
