Learning JavaScript - Chris Shiflett
Planet PHP7 Feb 2012 | 8:35 amOne of my goals this year is to acquire new skills, so I've decided to start by learning JavaScript. As was the case when I learned html and CSS, it's a tricky endeavor, because I'm not exactly a beginner, and most stuff is geared toward beginners, which can make learning so inefficient that I lose my motivation. I've decided to treat this effort just like I treat exercise, which is to focus on rhythm and consistency above all else. Don't break the chain. My days are packed, but I'm setting aside at least half an hour each day to do something related to learning JavaScript. As long as I hold… -
Musings on Preprocessing
CSS-Tricks8 Feb 2012 | 9:45 pmI've been using SASS for pretty much everything I do recently. Here's some musings on the journey. From hold-ups, to trip-ups, to turn-offs. From apps and teams to workflows and syntax. You Gotta Work Locally The biggest contributor to me getting on the bandwagon was giving up my going-commando live FTP editing ways. Yeah, Coda is awesome, but it's bad habit forming. It makes it way too easy to work live instead of local1. Working local is full of obvious advantages.

Coffee-themed bike racks
9 Feb 2012 | 7:13 amJava junkies that commute via bicycle get their coffee experience started before even walking in the door of Filter Coffeehouse & Espresso Bar in Washington, D.C.

8 historical figures who ate disgusting things
8 Feb 2012 | 11:26 pmBefore you read this article, you may have thought your dog had the grossest eating habits ever. But Fido's penchant for poo is nothing compared to some of these sickos highlighted in Cracked. For example, Victorian scientist William Buckland: He didn't just stop at the meat of animals, either. While on a visit to St. Paul's Cathedral, a strange mark was found on the floor. A debate broke out as to what the stain could possibly be, at which point Buckland got on his hands and knees, licked the stain and confidently announced it to be bat piss. But the craziest thing Buckland ever did, at…

The MicroPHP Follow-up FAQ - Ed Finkler
6 Feb 2012 | 9:00 pmMy previous post, The MicroPHP Manifesto, resulted in much excitement. In between fits of rage and crying, I found some time to answer folks questions, and also discuss the topic on the /dev/hell podcast with my cohost Chris Hartjes. To summarize and address some of the common questions, I felt I should write a small FAQ. Got a question? Ask me. I’ll add additional entries here as things come up. So you think full-stack frameworks suck? No. I think sometimes they’re very appropriate. It depends on your needs: will the pros you get with library/component/framework X outweigh the negatives? -

Content Security Policy update - Evert Pot
6 Feb 2012 | 2:57 pmA quick update about CSP. Browsers are well on their way to all adopt the specification. An early draft was already adopted by Firefox 4, and I just found out that it's also working in Chrome, Safari and IE 10. IE10 and FF are using the following header: XContentSecurityPolicy defaultsrc 'self' While Safari and Chrome use: XWebkitCSP defaultsrc 'self' When the specification is finalized, the X- will be dropped, and it will simply be 'Content-Security-Policy'. A call for support Hi Developers! Start implementing this feature! It's important for the future and security of the web. The web's…

Speech Bubble Arrows that Inherit Parent Color
6 Feb 2012 | 9:57 amInteresting question: css3 speech bubble question: for the "triangle"'s border color, how can I set it to whatever its parent div's bgcolor is automagically? — Jin Yang (@jzy) February 1, 2012 By "css3 speech bubble", Jin means using a pseudo element on a container to add a little pointer arrow (triangle). Not really CSS3, but that's pedantic. Let's say that pink color isn't practical to set in an external CSS file. Perhaps is a user setting, or perhaps its set dynamically somehow. <div class="speech-bubble" style="background: pink;"> I like bananas, because they have no bones. -
A proposal to drop browser vendor prefixes
3 Feb 2012 | 1:49 pmInteresting idea by Felipe G on using a new at-rule, @-vendor-unlock, to tell the browser to use it's experimental implementation of any particular property, rather than using a vendor prefix on that property. Unfortunately at this point, even if you could get all the browsers on board, you'd need to use this and vendor prefixes to get deep support, which makes the problem worse. What we really need is for all browsers to implement auto-updating so eventually "supporting older browsers" is something we can look back and laugh at.

Local used YUI 3 to develop their iOS app using a native Objective-C wrapper with HTML5 and YUI running in a UIWebView. He argues that there’s no such thing as a desktop web and a mobile web — there’s just “the web”, and YUI is the perfect framework for people who want to write web apps that run everywhere.

Shim uses node.js to test sites on multiple browsers
14 Jan 2012 | 8:01 pmShim was developed within the Boston Globe’s media lab as a way to study how Web sites look on various devices and browsers. A laptop intercepts all wifi traffic – this is redirected to a custom node.js server – which inserts a javascript, or “shim,” at the head of each web page that is visited. The shim, once loaded in a device’s browser, opens and maintains a socket connection to the server, according to to Shim’s developers. Shim was written in 2011 by Chris Marstall, Creative Technologist at the Boston Globe. The software has been open sourced. Write… -
HipHop Virtual Machine for PHP

We will no longer continue to develop Flash Player in the browser to work… -

Farewell Stack Exchange
6 Feb 2012 | 3:00 pmI am no longer a part of Stack Exchange. I still have much literal and figurative stock in the success of Stack Exchange, of course, but as of March 1st I will no longer be part of the day to day operations of the company, or the Stack Exchange sites, in any way. It's been almost exactly 4 years since I chose my own adventure. In those four years, we accomplished incredible things together.

Listen to Your Community, But Don't Let Them Tell You What to Do
3 Feb 2012 | 2:18 amYou know how interviewers love asking about your greatest weakness, or the biggest mistake you've ever made? These questions may sound formulaic, maybe even borderline cliche, but be careful when you answer: they are more important than they seem. So when people ask me what our biggest mistake was in building Stack Overflow I'm glad I don't have to fudge around with platitudes. I can honestly and openly point to a huge, honking, ridiculously dumb mistake I made from the very first day of development on Stack Overflow – and, worse, a mistake I stubbornly clung to for a solid nine month… -
The One Button Mystique
1 Feb 2012 | 1:15 pmI enjoy my iPhone, but I can't quite come to terms with one aspect of its design: Apple's insistence that there can be only ever be one, and only one, button on the front of the device. I also own a completely buttonless Kindle Fire, and you'll get no argument from me that there should be at least one obvious "Jesus Handle" button on the front of any gadget. I do wonder why Amazon decided to make the Fire buttonless, when every other Kindle they ship has a home button. Amazon has a track record of making some awfully rough version 1.0 devices; I'm sure they'll add a home button in a version… -
Defeating SOPA and PIPA Isn't Enough
18 Jan 2012 | 3:00 pmSOPA and PIPA are two pieces of proposed legislation designed to "stop" Internet piracy… in the most hamfisted way imaginable. As Mitchell Baker explains: Assume there's a corner store in your neighborhood that rents movies. But the movie industry believes that some or even all of the videos in that store are unauthorized copies, so that they're not being paid when people watch their movies. What should be done? SOPA/PIPA do not aim at the people trying to get to the store, or even the store itself. The solution under the proposed bills is to make it as difficult as possible to find or… -

Some pt-table-checksum FAQs
9 Feb 2012 | 2:55 amAfter the recent update to pt-table-checksum, I’ve seen a few FAQs about it. Q: is it still multi-threaded/parallel? A: No, that was a pile of bugs and complexity. If you need to run the tool in parallel to take advantage of powerful hardware, you can run several instances, say, one per database. Q: what chunk size should I use? A: None, let the tool adjust itself dynamically. Q: what if it skips a table or chunk because it’s oversized? A: this should be rare unless you have tables without any indexes; if you want to do the table in one chunk, run the tool again and specify to… -
MySQL/QueryScript use case: DELETE all but top N records per group
9 Feb 2012 | 12:33 amSome administrative tasks can be simplified by using common_schema/QueryScript. I'm collecting a bunch of these for documentation. Here's one for example: The DBA/developer has the task of retaining only top 3 most populated countries per continent. That is, she has to DELETE 4th, 5th, 6th, ... most populated counties in each continent. Is it possible to work out with a single query? Yes. But the query is not pretty. In fact, it is quite complicated, and either involves unintuitive subqueries, or unintuitive hacks. A normal DBA would not want to write, neither maintain this kind of query,… -

GTD Times: How do you get people to do what they said they would do?
7 Feb 2012 | 12:18 pmPeople who are starting with GTD often ask how to handle delegation, especially when a "waiting for" from another person doesn't get delivered as agreed. Here's a question and answer with David Allen on this topic. Question: I just finished the "Getting Things Done" book and I know the methods you have expressed will for sure help me! I was wondering if you can help answer one of my questions? For Actions, let's say you have to delegate work to someone. If that person doesn't do the work that they volunteer to, how do you act in a stress-free way which doesn't decrease your productivity and…

Designing Rails API using Rabl and Devise
8 Feb 2012 | 5:19 pmEnabling RESTful API access for Rails application is easy. However, the complexity arises when some responses are expected in xml format and JSON format.

Newman 0.2.0 Released!
8 Feb 2012 | 1:58 pmFor the last week or so, I've been trying to build a framework which does for email what Sinatra/Rack have done for web application development. It's not nearly production ready, but Newman now has good documentation of its implementation, and I'd love to hear what people think of it. I could really use some help, since email is not something I'm an expert on. -

7 Jan 2012 | 5:53 amRSpec 2.8 has been released, along with rspec-rails 2.8.1 for the full Rails 3.x integration experience. RSpec is a BDD-focused testing tool that's particularly popular in the Rails world where everyone except DHH is using it (if you believe the hoopla). RSpec has faced accusations of being less than speedy in the past, but it seems 2.8 has had a performance firework shoved up its tailpipe: David Chelimsky, the creator of RSpec, also notes that in RSpec 2.8: the documentation has been significantly improved there's improved support for tags and filtering random example running order support… -

How Not To Suck At PHP
2 Feb 2012 | 9:00 pmSince I hadn’t blogged for a bit I thought I would ask my Twitter peeps what they might want to hear my rant about. One of the more interesting suggestions I got was from Travis Northcutt who said the following: “Got it. I have no formal CS background, but I’m trying to learn enough to build (something). I know enough PHP to kind of, sort of get by but am trying to solidify my foundation. So if I’m being selfish, write a post to someone in my position who wants to not suck at building stuff.” This is actually a great question. Although the self-centered answer is… -
PHPUnit aborted fix
16 Jan 2012 | 9:00 pmA while back I ran into a problem on a server where PHPUnit kept reporting “aborted” no matter what tests were run. That was a pretty annoying bug. I never did find out what the problem was as I moved onto other problems and chalked that error up to some undiagnosed weirdness on that particular server. From time to time I would get asked on Twitter if I had ever solved the problem. My answer was always “no, and if you do solve it please let met know how you fixed it.” Today, my friends, was the day. Kudos to Damian Katz for coming up with a solution. Without digging… -
CodeMash 2012 Review
15 Jan 2012 | 9:00 pmLast week I attended CodeMash 2012 as a speaker and gave my talk on building testable PHP applications (don’t forget to buy the book that the talk inspired). Held in Sandusky, Ohio in the cold of January it is an interesting conference. Unlike most conferences that I attend, it is multi-disciplinary. There were talks on .NET, Java, Ruby, Python, and two lonely talks about PHP. For me, this is somewhat uncomfortable. It is only natural that people who use certain tools tend to flock together at a conference. I joked that where were only 3.7 PHP developers (with someone stating that the… -
Better Remote Code Development
4 Jan 2012 | 9:00 pmI am struggling to find a better way to handle a new paradigm in development. At Moontoast all our servers are up on EC2, which includes the two dev servers (one for each project) that I use every day. I’ve been playing around with Sublime Text (because of the awesome vim bindings) and was thinking about why do I always have to be logged into the remote server to do my work. Normally I connect using SSH, then attach to my tmux session and then fire up vim. This is okay but it lacks a certain elegance in it’s approach. As a result I end up using things like Dropbox to synchronize… -
The Grumpy Programmer’s Guide To Building Testable PHP Applications
2 Jan 2012 | 9:00 pmAfter the middling success of my first programming book I had been thinking about writing another book. When the end of October rolled around and National Novel Writing Month was about to happen I decided to take the plunge and write something. It didn’t turn out to be The Great Canadian Novel but I did collect my thoughts on what goes into building PHP applications in such a way that they are easily testable. I called it “The Grumpy Programmer’s Guide To Building Testable PHP Applications”. When I wrote my first book I did everything in Pages but that was before the…

A Craft Of Consequences: Reader, Writer And Emotional Design
8 Feb 2012 | 8:06 amBefore the very first page of a book has been read, you’ve already analyzed it in countless ways without even noticing. The paper stock, the thickness of the binding, the aroma, the color of the type and even the texture of the cover; the very character of the book is being dissected by the hand and eye at every moment. In this brief second there is a dialogue between the reader and the object. This conversation is subtle and complex, but for most people it is entirely subconscious. This is because we rarely think about these things — we feel them… -
Collaging: Getting Answers To The Questions You Don’t Know To Ask
6 Feb 2012 | 7:02 amWhen conducting user research, we all know that asking the right questions is just as important as how you ask them, but how do you know exactly what questions to ask? What if the discussion topic is very personal? How do you get a complete stranger to open up? There is a better way to conduct an in-depth interview, and it doesn’t involve a clipboard. Just imagine what you could discover if the participant’s answers weren’t limited to a predetermined set of questions. This is where collaging can help. Collaging is a projective technique by which participants select images… -
How To Use Custom Post Types To Organize Online Marketing Campaigns
3 Feb 2012 | 7:04 amCustom post types add a level of flexibility to WordPress that makes this open-source Web development platform more useful on many levels. Whenever I have been faced with a Web-based task, especially one that involves organizing information, the first thing I do is examine WordPress to determine if it can handle the job. It usually can. Image Source As an Internet marketer and analyst, I need to be able to organize online marketing campaigns in a way that is trackable in Google Analytics. This is the perfect task for WordPress custom post types. In this article, we’ll explain… -

Responsive Images: How they Almost Worked and What We Need
31 Jan 2012 | 4:00 amWith a mobile-first responsive design approach, if any part of the process breaks down, your user can still receive a representative image and avoid an unnecessarily large request on a device that may have limited bandwidth. But with several newer browsers implementing an “image prefetching” feature that allows images to be fetched before parsing the document’s body, some of the web's brightest developers are abandoning responsive images in favor of user agent detection, at least as a temporary solution. For us standardistas, UA detection leaves a bad taste in the mouth. More… -
Pricing Strategy for Creatives
31 Jan 2012 | 4:00 amStrategic pricing helps your brand and helps you to make more money. Issuing a price is like handing out a business card—it’s a great branding tool, but be careful about what it says to your market. Beginning relationships with customers at a high price makes the statement: “we’re good at what we do and we know it.” Fighting with a competitor over a low price says “I’m uncertain about my abilities, so I’ll take what I can get.” Failing to use a considered pricing policy will leave you treading water in a sea of design mediocrity, allowing you to just stay afloat while you… -
Building Twitter Bootstrap
17 Jan 2012 | 1:00 amBootstrap is an open-source front-end toolkit created to help designers and developers quickly and efficiently build great stuff online. Its goal is to provide a refined, well-documented, and extensive library of flexible design components created with HTML, CSS, and JavaScript for others to build and innovate on. Today, it has grown to include dozens of components and has become the most popular project on GitHub, with more than 13,000 watchers and 2,000 forks. Mark Otto, the co-creator of Bootstrap, sheds light on how and why Bootstrap was made, the processes used to create it, and how it… -
An Important Time for Design
17 Jan 2012 | 1:00 amDesign is on a roll. Client services are experiencing a major uptick in demand, seasoned design professionals are abandoning client work in favor of entrepreneurship, and designer-co-founded startups such as Kickstarter and Airbnb are taking center stage. It’s becoming increasingly difficult to ignore the fact that design has a massive role to play in the evolution of the web and the next generation of web products. The result, says Cameron Koczon, is that designers have now been given a blank check—one that lets web designers band together as a community to change the way design is… -
A Pixel Identity Crisis
17 Jan 2012 | 1:00 amThe pixel has long been the atomic particle of screen based design: a knowable, concrete unit of measurement. But layouts based on the hardware pixel are fast becoming an endangered species. Even the introduction of a new, W3C standard reference pixel, although it promises stability in the long-term, can't help us navigate the current chaos. Consider the two "standard" pixel definitions and 500 "standard" viewports your user's Android device may support. To create designs that transcend platform differences—the promise of the web and standards—you must normalize pixels across devices.

Are There Problems Web Apps Can’t Solve?
9 Feb 2012 | 6:00 amI’m a developer, have been for a long time. I’ve been wrting code for the web for the past decade in my life.
