Apple co-founder Steve Jobs dead at 56
Apple CEO Steve Jobs talks about the iCloud service at the Apple Worldwide Developers Conference in San Francisco, California, June 6, 2011.
Apple Inc co-founder and former CEO Steve Jobs, counted among the greatest American CEOs of his generation, died on Wednesday at the age of 56, after a years-long and highly public battle with cancer and other health issues.
Jobs’ death was announced by Apple in a statement late on Wednesday.
The Silicon Valley icon who gave the world the iPod and the iPhone resigned as CEO of the world’s largest technology corporation in August, handing the reins to current chief executive Tim Cook.
Jobs, who fought a rare form of pancreatic cancer, was deemed the heart and soul of a company that rivals Exxon Mobil as the most valuable in America.
The HTML5 boom is coming. Fast.
The tech industry’s movers and shakers have been saying for months now that the HTML5 is very important. New data released Friday indicates that HTML5 is not just going to be big, it’s going to be huge — and it’s coming fast.
More than 2.1 billion mobile devices will have HTML5 browsers by 2016, up from just 109 million in 2010, according to a new report by ABI Research. Much of this growth will be thanks to Apple’s massive support for the HTML5 platform, according to the study. And Apple is also likely to be one of the biggest beneficiaries of the technology’s wide scale adoption. Because Apple has so much control over its software and devices, it will be most poised to take full advantage of HTML features as they emerge in the coming years.
As is often the case in business, where there’s a winner, there’s usually a loser. HTML5 could largely replace Abobe’s proprietary Flash technology. And HTML5′s swift ascent could render Flash irrelevant in short order. “I think the disappearance of Flash is closer than people think,” ABI senior analyst Mark Beccue said in a press release accompanying the data.
HTML5′s projected growth is all the more impressive considering that the actual standard is not officially expected to be completed until 2020, according to the World Wide Web Consortium (W3C) standards body. But that won’t stop companies and independent engineers from developing and deploying HTML5 features, ABI said.
Indeed, Facebook CTO Bret Taylor has said his company is putting a “huge amount of our investment” in HTML5, and Google recently debuted its first homepage doodle composed entirely with the HTML5 mark-up language. It may seem like buzz about HTML5 is everywhere already, but if the latest research is correct, we’re only at the beginning.
HTTP Status Codes Explained
All valid HTTP 1.1 Status Codes simply explained.
HTTP, Hypertext Transfer Protocol, is the method by which clients (i.e. you) and servers communicate. When someone clicks a link, types in a URL or submits out a form, their browser sends a request to a server for information. It might be asking for a page, or sending data, but either way, that is called an HTTP Request. When a server receives that request, it sends back an HTTP Response, with information for the client. Usually, this is invisible, though I’m sure you’ve seen one of the very common Response codes – 404, indicating a page was not found. There are a fair few more status codes sent by servers, and the following is a list of the current ones in HTTP 1.1, along with an explanation of their meanings.
A more technical breakdown of HTTP 1.1 status codes and their meanings is available at http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html. There are several versions of HTTP, but currently HTTP 1.1 is the most widely used.
Informational
- 100 – Continue
A status code of 100 indicates that (usually the first) part of a request has been received without any problems, and that the rest of the request should now be sent. - 101 – Switching Protocols
HTTP 1.1 is just one type of protocol for transferring data on the web, and a status code of 101 indicates that the server is changing to the protocol it defines in the “Upgrade” header it returns to the client. For example, when requesting a page, a browser might receive a statis code of 101, followed by an “Upgrade” header showing that the server is changing to a different version of HTTP.
Successful
- 200 – OK
The 200 status code is by far the most common returned. It means, simply, that the request was received and understood and is being processed. - 201 – Created
A 201 status code indicates that a request was successful and as a result, a resource has been created (for example a new page). - 202 – Accepted
The status code 202 indicates that server has received and understood the request, and that it has been accepted for processing, although it may not be processed immediately. - 203 – Non-Authoritative Information
A 203 status code means that the request was received and understood, and that information sent back about the response is from a third party, rather than the original server. This is virtually identical in meaning to a 200 status code. - 204 – No Content
The 204 status code means that the request was received and understood, but that there is no need to send any data back. - 205 – Reset Content
The 205 status code is a request from the server to the client to reset the document from which the original request was sent. For example, if a user fills out a form, and submits it, a status code of 205 means the server is asking the browser to clear the form. - 206 – Partial Content
A status code of 206 is a response to a request for part of a document. This is used by advanced caching tools, when a user agent requests only a small part of a page, and just that section is returned.
Redirection
- 300 – Multiple Choices
The 300 status code indicates that a resource has moved. The response will also include a list of locations from which the user agent can select the most appropriate. - 301 – Moved Permanently
A status code of 301 tells a client that the resource they asked for has permanently moved to a new location. The response should also include this location. It tells the client to use the new URL the next time it wants to fetch the same resource. - 302 – Found
A status code of 302 tells a client that the resource they asked for has temporarily moved to a new location. The response should also include this location. It tells the client that it should carry on using the same URL to access this resource. - 303 – See Other
A 303 status code indicates that the response to the request can be found at the specified URL, and should be retrieved from there. It does not mean that something has moved – it is simply specifying the address at which the response to the request can be found. - 304 – Not Modified
The 304 status code is sent in response to a request (for a document) that asked for the document only if it was newer than the one the client already had. Normally, when a document is cached, the date it was cached is stored. The next time the document is viewed, the client asks the server if the document has changed. If not, the client just reloads the document from the cache. - 305 – Use Proxy
A 305 status code tells the client that the requested resource has to be reached through a proxy, which will be specified in the response. - 307 – Temporary Redirect
307 is the status code that is sent when a document is temporarily available at a different URL, which is also returned. There is very little difference between a 302 status code and a 307 status code. 307 was created as another, less ambiguous, version of the 302 status code.
Client Error
- 400 – Bad Request
A status code of 400 indicates that the server did not understand the request due to bad syntax. - 401 – Unauthorized
A 401 status code indicates that before a resource can be accessed, the client must be authorised by the server. - 402 – Payment Required
The 402 status code is not currently in use, being listed as “reserved for future use”. - 403 – Forbidden
A 403 status code indicates that the client cannot access the requested resource. That might mean that the wrong username and password were sent in the request, or that the permissions on the server do not allow what was being asked. - 404 – Not Found
The best known of them all, the 404 status code indicates that the requested resource was not found at the URL given, and the server has no idea how long for. - 405 – Method Not Allowed
A 405 status code is returned when the client has tried to use a request method that the server does not allow. Request methods that are allowed should be sent with the response (common request methods are POST and GET). - 406 – Not Acceptable
The 406 status code means that, although the server understood and processed the request, the response is of a form the client cannot understand. A client sends, as part of a request, headers indicating what types of data it can use, and a 406 error is returned when the response is of a type not i that list. - 407 – Proxy Authentication Required
The 407 status code is very similar to the 401 status code, and means that the client must be authorised by the proxy before the request can proceed. - 408 – Request Timeout
A 408 status code means that the client did not produce a request quickly enough. A server is set to only wait a certain amount of time for responses from clients, and a 408 status code indicates that time has passed. - 409 – Conflict
A 409 status code indicates that the server was unable to complete the request, often because a file would need to be editted, created or deleted, and that file cannot be editted, created or deleted. - 410 – Gone
A 410 status code is the 404′s lesser known cousin. It indicates that a resource has permanently gone (a 404 status code gives no indication if a resource has gine permanently or temporarily), and no new address is known for it. - 411 – Length Required
The 411 status code occurs when a server refuses to process a request because a content length was not specified. - 412 – Precondition Failed
A 412 status code indicates that one of the conditions the request was made under has failed. - 413 – Request Entity Too Large
The 413 status code indicates that the request was larger than the server is able to handle, either due to physical constraints or to settings. Usually, this occurs when a file is sent using the POST method from a form, and the file is larger than the maximum size allowed in the server settings. - 414 – Request-URI Too Long
The 414 status code indicates the the URL requested by the client was longer than it can process. - 415 – Unsupported Media Type
A 415 status code is returned by a server to indicate that part of the request was in an unsupported format. - 416 – Requested Range Not Satisfiable
A 416 status code indicates that the server was unable to fulfill the request. This may be, for example, because the client asked for the 800th-900th bytes of a document, but the document was only 200 bytes long. - 417 – Expectation Failed
The 417 status code means that the server was unable to properly complete the request. One of the headers sent to the server, the “Expect” header, indicated an expectation the server could not meet.
Server Error
- 500 – Internal Server Error
A 500 status code (all too often seen by Perl programmers) indicates that the server encountered something it didn’t expect and was unable to complete the request. - 501 – Not Implemented
The 501 status code indicates that the server does not support all that is needed for the request to be completed. - 502 – Bad Gateway
A 502 status code indicates that a server, while acting as a proxy, received a response from a server further upstream that it judged invalid. - 503 – Service Unavailable
A 503 status code is most often seen on extremely busy servers, and it indicates that the server was unable to complete the request due to a server overload. - 504 – Gateway Timeout
A 504 status code is returned when a server acting as a proxy has waited too long for a response from a server further upstream. - 505 – HTTP Version Not Supported
A 505 status code is returned when the HTTP version indicated in the request is no supported. The response should indicate which HTTP versions are supported.
The Poetics Of Coding
There is little doubt that WordPress is one of the most popular blogging and content management platforms out there today. This is not an article about WordPress, though, but rather a more general musing on one of its thought-provoking taglines: “Code Is Poetry.”
That’s an interesting metaphor. Recently, I’ve written about the different languagesused by designers and developers, and also about the relationship between these coding languages and proper human language (specifically, English). As someone who graduated from university with a degree in English Literature and came to Web design in a roundabout way, this kind of thinking has always interested me.
40 Useful jQuery Techniques and Plugins
In this post, we present 40 useful but obscure jQuery plug-ins that will hopefully help you improve the user experience on your websites. We look forward to your ideas and suggestions in the comments to this post.
Tips, Hints, Navigation
TipTip jQuery Plugin
TipTip detects the edges of the browser window and will make sure the tooltip stays within the current window size. As a result the tooltip will adjust itself to be displayed above, below, to the left or to the right of the element with TipTip applied to it, depending on what is necessary to stay within the browser window. TipTip is a very lightweight and intelligent custom tooltip jQuery plugin. It uses ZERO images and is completely customizable via CSS.
Seven JavaScript Things I Wish I Knew Much Earlier In My Career
I’ve been writing JavaScript code for much longer than I care to remember. I am very excited about the language’s recent success; it’s good to be a part of that success story. I’ve written dozens of articles, book chapters and one full book on the matter, and yet I keep finding new things. Here are some of the “aha!” moments I’ve had in the past, which you can try out rather than waiting for them to come to you by chance.
Usability Do’s And Don’ts For Interactive Design
We often talk about how to make our websites more usable, whether it’s tweaking the HTML structure of pages to benefit the user’s process or figuring out how best to display a message via CSS. But we never bring this thought process into our jQuery-based (and other JavaScript-based) elements. How can we enhance the user experience and usability of our jQuery events?
Below, we’ll briefly discuss ways to look at the code and the result of our interactive designs and, thus, improve their usability.

Joomla And WordPress: A Matter Of Mental Models
Open-source content management systems (CMS) are a large family of Web applications, but if we’re looking for stability, performance and average technical requirements, we’ll come up with a handful of options. In the past, choosing the “right” CMS was a matter of the project’s requirements, but now this is not completely valid because the paradigm of extensibility had driven the development of major CMS’ towards a model of core features that are extensible with plug-ins that fill virtually any requirement.
Picking the right CMS is then a matter of “mental models”: choosing the one that best fits our vision of how a Web application should work and what it should provide to users and administrators. In this article, we’ll explore the main difference in the mental models: of WordPress and Joomla for theming and extending their core.
Using ODBC you can connect MySQL with ASP.NET
Takeaway: The popular MySQL database application is no stranger to the Microsoft Windows platform. You can use ODBC to connect to MySQL databases with ASP.NET.
Considered the “world’s most popular open source database,” MySQL has come a long way from its beginnings as a no-frills, low-cost database server to one that powers high-volume Web sites and critical business systems. If you’re an ASP.NET developer, though, there’s always been one tiny glitch: MySQL was originally targeted at applications on the UNIX platform, with Windows support a secondary priority.
Today, however, the Windows version of MySQL is as full-featured and stable as the UNIX version, and it is considered a viable database server for Windows development. Let’s look at how you can use ODBC to connect to MySQL databases within the .NET Framework.

Really Useful Classes And Libraries For PHP Developers
Today millions of websites and servers across the Internet are powered by PHP. Originally created by Rasmus Lerdorf in 1995 so that anyone can easily create a Personal Home Page; PHP has come a long way and is now widely used as general purpose scripting language that is suitable for majority of web development projects.
Numerous PHP Frameworks have evolved to enable rapid web development with PHP. However even greater number of standalone PHP libraries and classes are available which provide similar benefits. W3Avenue has compiled a list of some really useful classes and libraries that every PHP developers should be familiar with. Whether you like to use a PHP Framework or prefer to work without one, your productivity can multiply with the help of these libraries and classes.
List of Really Useful JavaScript Libraries
Popular JavaScript frameworks probably provide every common function a developer may need. The ability to extend these frameworks with new plugins makes them even more powerful. But you may still face situations when you don’t want to use these frameworks or you may find lack of support for specialized functions. This is where a lot of really useful stand alone JavaScript libraries can provide help.
W3Avenue has compiled a list of really useful standalone JavaScript libraries that will help you when your favorite JavaScript framework like Prototype, jQuery, MooTools, etc don’t provide functions for your specific needs or you prefer not to use them for some reason.
Create YouTube-like adaptable view using CSS and jQuery
Besides Turn off the lights feature I explained earlier, YouTube has more great stuff. I believe that you noticed “change view” feature which allows you to switch between normal and wide mode and thus expand/shrink movie area. I like this feature because in different circumstances, I need a different view. But the thing I like the most is that, although layout changes, it is done seamingly and all the information remains easily accessible.

Create a Letterpress Effect with CSS Text-Shadow
The letterpress effect is becoming hugely popular in web design, and with a couple of modern browsers now showing support for the text-shadow CSS3 property it’s now simple and easy to create the effect with pure CSS. No Photoshop trickery here!
Letterpress – Isn’t that a type of industrial print method? That’s right! But the effect has also made its way into web design. Check out the previous feature showcasing examples of how designers are using this cool ‘de-bossed’ look on designs across the web.
Top 10 best practices for front-end web developers
Explain which div you’re closing
Most of the time when I’m viewing a website source, I see, at the very bottom of the page, an almost endless list of closing </div> tags. In fact, many beginners think they just have to use divs instead of tables to produce quality code. Divs are cleaners than tables, but without proper code organization, it can be as (or even sometimes more) messy as table based code.
Using indentation is a good start. But a tip that can definitely make you save lot of time is to comment every div tag you’re closing, as shown in the example below:
1.<div id="header">2. <div id="sub" class="first left">3. ...4. </div><!-- #sub.first.left -->5.</div><!-- #header -->
