HTML5
A technical specification for Web developers

This HTML5 specification is like no other—It has been processed with you, the humble web developer, in mind.

The focus of this specification is readability and ease of access. Unlike the full HTML specification, this "web developer edition" removes information that only browser vendors need know.

To read about its conception, construction and future, read the press release.

“Can you recommend a good book for getting started with Objective-C?”

I get this question a lot, but there’s no need to spend any money or even to spend time digesting an entire book. I always point people to the Apple docs — the documentation is very modular and (mostly) very reliable.

But the sheer volume of documentation can be intimidating. So this is a list of articles, arranged in the order that I recommend you read to get started writing your first iPhone app. You can work through the whole list in a day or two. I’ve learned everything I needed to ship about 20 apps between the docs and a lot of Googling — this list is based roughly on the path I took through the docs to get started, and I think it will serve you well.

The only prerequisite you need is some knowledge of C and OOP. Let’s get started:

A number is prime if it is only divisible by 1 and itself. So for example 2, 3, 5, 79, 311 and 1931 are all prime, while 21 is not prime because it is divisible by 3 and 7. To find if a number n is prime we could simply check if it divides any numbers below it. We can use the modulus (%) operator to check for divisibility:

So I've helped at least a dozen or so people on this subreddit rewrite their resumes, and I put together something on the advice I give the most:

Learning something new is scary. For me, the biggest issue with picking up a new skill is that I don’t know what I don’t know. Given that, it’s often useful to find a plan for learning whatever you’re interested in. That’s what this post is: your blueprint, your roadmap, your plan of action for learning JavaScript! You don’t have to worry about finding the best resources, sorting out the bad ones, and figuring out what to learn next. It’s all here. Just follow it, step by step.

The Columnal CSS grid system is a “remix” of a couple others with some custom code thrown in. The elastic grid system is borrowed from cssgrid.net, while some code inspiration (and the idea for subcolumns) are taken from 960.gs. Check out the demo.

This Django application provides management commands to help backup and restore your project database to AmazonS3, Dropbox or Local Disk.

tmux is similar to screen as it lets you run numerous TTY’s in the same terminal window. It supports some very cool and intuitive features natively as well as a much more readable configuration syntax (ever looked at a .screenrc file?).

Have you ever needed to get query string values using JavaScript? This task is usually a painful split, split, split, iterate, indexOf hack that is really slow and terribly ugly to look at. It also tends to pile up lines of code really fast.

Here is a really sweet way to parse the query string into a JavaScript object with two lines of code using regular expressions to populate an object. I discovered this trick a few years ago and filed it away in my code snippets folder.

This page lists open source projects and applications regarding Django, the framework for perfectionists with deadlines.

Feel free to update this page to improve the content as you see an opportunity to add or modify a resource, or to remove any unmaintained project from the list.

This page lists Racket projects which are feasible for people who don't have a lot of experience with the Racket code base. They're mostly small, self contained, and would be extremely useful. Some involve writing a new library that would be useful to lots of other people, and some help fix or clean up some aspect of the existing Racket code base.

Lush is an object-oriented programming language designed for researchers, experimenters, and engineers interested in large-scale numerical and graphic applications. Lush is designed to be used in situations where one would want to combine the flexibility of a high-level, weakly-typed interpreted language, with the efficiency of a strongly-typed, natively-compiled language, and with the easy integration of code written in C, C++, or other languages.

xec Summary: Today I’m launching a Beta open source project called DeployMint. I’m using it on WordPress installations where WordPress is being used as a CMS. It runs as a WordPress plugin and allows for staging and deployment of WordPress sites along with robust version control and zero down-time during deployments. It uses the Git version control system to store site snapshots in a safe and space efficient way. It also takes a “belt and braces” approach and provides an emergency back-out system separate to Git in case a deployment fails. You can download the latest version of DeployMint and see a video demo at the DeployMint project page on Google Code.

Bootstrap is a toolkit from Twitter designed to kickstart development of webapps and sites.
It includes base CSS and HTML for typography, forms, buttons, tables, grids, navigation, and more.
Nerd alert: Bootstrap is built with LESS and was designed to work out of the gate with only modern browsers in mind.

Writing a flashcard application is almost a rite of passage for django users. You create a simple Card model, you create a quiz view and template and you call it a day. A simple application and not very useful.

Yesterday I tweeted three simple rules to learning NoSQL. Today I'd like to expand on that. The rules are:

1: Use MongoDB. 2: Take 20 minute to learn Redis 3: Watch this video to understand Dynamo.
Before we get going though, I want to talk about two different concepts which'll help us when we talk about specific technologies.

Are you a software developer applying to a small company?

Here’s a tip from someone who has read thousands of resumes. When you’re applying to a startup, or a software company with less than, say, 100 employees, you may want to highlight the Banging Out Code parts of your experience, while deemphasizing the Middle Management parts of your experience.

Crash into Python is a set of documents/slides that are meant to be used as a teaching aid for bringing programmers from other languages up to speed with Python. It assumes that you have enough familiarity with programming to know what function and class mean, and will recognize that print probably doesn't put ink on paper. More importantly, it assumes that you either have an instructor who is well-versed in Python, or are resourceful enough to find answers for yourself. A number of these slides are designed to trigger questions and discussion, so if it seems like you're missing something, that's a good sign you could be digging deeper.

Here is advice for anyone who hasn't gone to college yet. First off, it's not all horror storries. There's a site called fastweb.com where you fill out a really long questionnaire and it will apply you for every scholarship you could possibly qualify for. There aren't may big ones, but I got little ones like 300 dollars a semester for being left handed, 500 a semester just for writing how coca cola made a happy childhood memory, and a few others. Then you can apply for grants and more scholarships for anything you can think of that makes you different. After that, take the loans out, but only use them for what you need. Often there's extra money in your disbursement, put it in a bank account and sit on it, or use it to pay back the loan itself. It's very easy to see the extra and "need" a laptop for school, or "need" to not live in the dorms. Do not spend it. It's easy to do. 1500 in the bank, you see a new game or clothes or new phone and it will call to you. Don't do it. Major in something you know will get a job. Sciences, Medicine, Math, Accounting, Engineering, etc. Don't do what you love. Do what you love as a hobby, something to relax you from your job. Make sure you do well in classes, GO to them ALWAYS (if you miss more than 2 a semester, you're doing it wrong) and above all else, make sure you're not just shuffling in and out of class. Remember you will need connections. Your professors are the gatekeepers into your field, every single one should know you by first and last name. Sit up front. If you go to a community college for two years, then a respected university for the last two, do you know where your degree will be from? Respected University. There's zero difference besides tens of thousands of dollars. Plus, it casts your circle of influential professors even wider. Always be looking for experience, free or not. Apply to be a lab assistant in whatever field you choose. Work on campus, Do well and influence people, and when the time comes you'll have zero problems rising to the top. Go forward and give everyone more than they expect.

Whats more amazing is that Eric lays out the first steps for you to start shaping up your business to really make money and WE'VE GOT IT ALL. But be careful once you start watching it you might not finish because, like me, you will have to get back to work implementing all the good stuff Eric is talking about.

The detailed version of Lightning Talk:

So you've decided to learn Python. Maybe you've already taken a look at the Python site. But where to begin? Are there good books for learning? Programming exercises? What are essential tools one must know about? I've gotten these questions from several interested friends and colleagues. Each time, I tried to reply with a helpful mail. At some point I realized that a nice write-up as blog post would serve just as well and allow other people to benefit, too.

Exambuff was my exam preparation startup. I failed because I didn't know my customers, wrote code too early, tried to sell to institutions and didn't find a co-founder. Please take the code (30k lines, PHP/Flex), design & docs and make a go of the business.

Of course, a big problem with most corners of the internet is labeling. One of our most consistently frustrating issues is trying to figure out whether two ticket listings are for the same real-life event (that is, without enlisting the help of our army of interns).

In this post I've collected a lot of links on the topic of 64-bit C/C software development. These include my articles and articles by my colleagues in the sphere of developing safe and efficient 64-bit code; FAQ's and a training course. There are also many reviews of third-party articles on 64-bit software development. Enjoy yourself studying the materials.

The editor on this page is using wysiwym (What You See Is What You Mean). It is not meant to be used to output HTML, it simply helps with the desired markup syntax. Currently supported are Markdown, MediaWiki, and BBCode. With a little help from other projects it can be used to create a live HTML preview editor similar to what StackOverflow has. Simpler examples can be found here.

For the past year and a half or so I’ve been working full-time at Dumbwaiter Design doing Django development. I’ve picked up a bunch of useful tricks along the way that help me work, and I figured I’d share them.

This booklet has been produced for students at the University of New South Wales taking courses 6.602B and 6.657G. It is intended as a companion to, and commentary on, the booklet UNIX Operating System Source Code, Level Six.

In the jargon of the computer programmer, a hacker is someone who strives to solve problems in elegant and ingenious ways. Part of the path to elegantly solving larger problems is to use tools that solve sub-problems very well. For the modern Python programmer, some of the most important tools to aid in reduced complexity and repetition are virtualenv, Fabric, and pip. Although these tools have no strict relationship (in the sense that many people may use one or two of these tools often, yet aren't even aware of the others), they form a powerful suite when combined. An excellent example is the following:

I haven’t updated this blog in a while. That’s partly because we’ve had a lot going on, and partly because I wanted to first get the big fucking monkey off my back. i.e. I wanted to wait until I started to get new users and content onto Get Comparisons. Which I’m happy to say… we’ve been successful at doing! So with a big sigh of relief I return to blogging.

Best place to start is locate somebody close to you through an ABANA chapter. They can clue you in to teachers, anvils, and supplies. Buying an anvil is the biggest thing, don't buy a modern cast iron one, they don't work for shit. Save your money for a good old one and make due with a section of railroad track. You can sometimes find hammers and tongs at flea markets. The forge can be done many ways, you'll have to explore options before you get into that.

The most important consideration for the majority of our clientele when sending anonymous secure email is his or her personal anonymity.

This is a series of pages that guide you through the creation and operation of a successful consulting business. I've written this after running a fairly successful consultancy business in the mid-90's and reviving this business in 2008. I'm primarily active in software, so some of the things in here will be skewed in that direction, but I'll do my best to keep it general, and to make it 'location independent'.

In order to moderate a W3C mailing list, one needs to be able to bounce a message.  This apparently isn’t directly possible with gmail, but can be worked around manually:From the message dropdown, select Show original, then from the browser select Save Page As....With a text editor, find the line containing X-From_:.  Copy this line to the top of the file, then modify that first line by removing the X- and _: characters.  Save the file.Now you case use mutt on that file (example: mutt -f mail.google.com) and use the b command to bounce the message.  Enter the name of the mailing list (example: public-html@w3.org), press enter and then y to confirm.Perhaps if I need to do this often enough, I’ll automate the process, but for now these notes will help should I need to do the process again in the future.

Johnston (or Johnston Sans) is a humanist sans-serif typeface designed by and named after Edward Johnston. It is well-known for its use by Transport for London.Johnston's former student Eric Gill also worked on the development of the typeface,[1] which was later to influence his own Gill Sans typeface, produced 1928–32.

I get it, you want to learn how to program and how to be a hacker, fine let’s do this. It sounds tough but you’ll want to learn two languages for your first time: Ruby and Python. They are similar in syntax and usage cases so this shouldn’t be a big problem. Pick up the basics, the syntax, and the community standards of each. Understand that each has it’s own power and use as well as problems. Read these two books front to back for as long as they interest you, they’re made for beginners so don’t be afraid!

While reading what follows, please remember that I do not sell financial calculators, nor do I receive any kind of remuneration from calculator manufacturers or retailers. Furthermore, I have purchased all of the financial calculators on this site with my own money (over many years). Therefore, my suggestions are based solely on more than 20 years of teaching experience and my personal preferences. Am I biased? Of course. My personal preference is for Hewlett Packard calculators that support RPN data entry (the HP 12C and the HP 17BII). However, RPN is not familiar to most people and I wouldn't expect you to learn it if you don't need to.

For quite a while, I used X-Chat as my primary IRC client, but I wasn't impressed with the features X-Chat offered. It seemed uncustomizable and static. After a few months of using X-Chat, I tried Irssi and immediately found it to be the most intuitive and easy to use IRC client yet. It has the features I want in an IRC client and I have been using Irssi ever since. I have already succeeded in converting a few of my friends to Irssi, and with this guide, I hope to show the light to others.

Entrepreneurs are always looking for an easy way to make a big PR splash.  If you are a local business that only serves a specific geographic area, then your local newspaper is still probably your best option for some free publicity.  On the other hand, if you offer a product or service that is available in multiple locations or via the Internet, then you must consider the following websites in which to submit your company to, and gain free publicity.

So you have a new startup company and want some coverage. This post will give you 36 places where you can submit your startup for reviews, mentions or at least some backlinks.

The web development scene is moving forward at a lightning-fast pace, and it’s imperative that developers continue to keep their skills fresh. If you’ve been involved in front-end design or development in any form over the past five years or so, then it’s very likely that you’ve experimented at some point with one of the popular JavaScript libraries, many of which have become quite prominent and are now used on a number of large commercial websites.

Not too long ago I wrote an article for Six Revisions called Getting Started with jQuery that covered some important things (concept-wise) that beginning jQuery developers should know. This article is the complete opposite; there’s no concepts, no principles, and very little lecturing — just some straight example code with brief descriptions demonstrating what you can do with jQuery.
