• Is "PHP and MySQL Web Development, 4th ed." an outdated book to learn from?

  - by ForeverLearnNeverMaster

  I want to get into web stuff, and thought of going with PHP+MySQL. I have experience in C#, C++, desktop graphics, but no web stuff besides HTML, CSS which I started learning 2 months ago. On SO PHP-book question, the highest rated book is "PHP Objects, Patterns and Practice". However, I'm not sure if it's a book to start PHP with... or is it? Most of the books mentioned in that SO question seem to be for those who already know PHP. I considered "PHP & MySQL Web Development, 4th Ed.", but someone mentioned that "it uses the mysql_* functions which are almost deprecated." Help?

• How to get rid of the background gradient of the inline GtkToolbar?

  - by Dima

  When you run the below code, it will show an inline toolbar in a window. Notice how the inline toolbar has a stand-out backbround. Is there a way to apply CSS to get rid of it and make blend with regular window color? #!/usr/bin/python3 from gi.repository import Gtk button_names = [Gtk.STOCK_ABOUT, Gtk.STOCK_ADD, Gtk.STOCK_REMOVE, Gtk.STOCK_QUIT] buttons = [Gtk.ToolButton.new_from_stock(name) for name in button_names] toolbar = Gtk.Toolbar() toolbar.set_show_arrow(False) for button in buttons: toolbar.insert(button, -1) style_context = toolbar.get_style_context() style_context.add_class(Gtk.STYLE_CLASS_INLINE_TOOLBAR) grid = Gtk.Grid() grid.add(toolbar) label = Gtk.Label() grid.add(label) window = Gtk.Window() window.set_size_request(200, 50) window.add(grid) window.connect('delete-event', Gtk.main_quit) window.show_all() Gtk.main()

• How do I apply a computer science degree to web development?

  - by T. Webster

  I'm a web programmer, but I haven't found many opportunities to take advantage of a formal education in computer science. Maybe I'm not looking in the right places, but it seems to me like most of the web jobs I come across are CRUD, web forms, and data grids. For these jobs a formal CS background doesn't seem necessary, and you could do fine with O'Reilly cookbooks in jQuery, CSS 3, PHP, SQL, or ASP.NET MVC. What kinds of web developer jobs exist that really let you apply your computer science background? Do I need to branch out into other areas of programming to take full advantage of my degree?

• Is it possible for a web-server to send more files than requested for, and have the browser accept them?

  - by Osiris

  I've created a basic web server for a school project, and it serves static content without a problem. I thought of having the server parse all htm/html files for links to .js/.css/image files, and send these files to the client without these files being requested by the client later. eg. The browser requests: index.htm The server responds with intex.htm and image.jpg I modified the server to send two distinct http responses for a "GET /index.html HTTP1.1" (one for the html page and one for the image), but the browser ended up requesting the image when it was good and ready. Is there any way to bypass this? (use a multipart response, perhaps) Will these files be accepted by most browsers, or will they be rejected for security reasons?

• New Look for Geekswithblogs.net Homepage

  - by Jeff Julian

  I wanted to alert everyone to the new look of the Geekswithblogs.net Community Page.  I removed the tabs, cleaned up the posts and fonts, replaced the logo with our brighter logo, and mucked with the CSS and HTML to drive a smaller footprint.  With this update, the homepage is now HALF THE SIZE in KBs!  I still have some more AJAX calls I want to implement to make the footprint even smaller. Let me know what you think.  I feel it is easier to read through the posts now.

• Which is easier to learn, Zend Framework, CakePHP or CodeIgniter?

  - by Kwame Boame

  I am new to programming but I know HTML, CSS and Jquery. I am a web designer but want to expand my skill to application development with frameworks. Specifically, PHP frameworks. I want to know which of the frameworks mentioned in the question is difficult to master. Also, my friend wants me to learn Ruby on Rails/ Python instead of PHP. What's your best advice for a newbie programmer who is looking to build online software/apps in the near future; say, after 3 months/6 months or a year of study and practice?

• All around design book for a developer (Javascript dev)

  - by Alex Angelini

  I have begun doing a lot of javascript development recently, mostly front-end but also using node.js. As I am currently in the transition from large company to startup, they expect me as a front end developer to know how to produce semi decent designs (Which I cannot) I am looking for a book (or set of screencasts) to give me some good well rounded advice on design. I know CSS, but my design are always awful looking, I also know nothing about Photoshop (and am on Linux and have no access to it) What are your picks? I am not looking to be a full time designer I would just like to be able to contribute.

• Software engineering project idea feedback [on hold]

  - by Chris Sewell

  I'm a third year student currently undergoing my project/dissertation section of my degree. I have drafted a proposal for my final year project and would appreciate any feedback. The feedback can be anything constructive either specific to this proposal, the area that I will be working and researching in or my ideas. I will accept all input. Aims My aim is to attempt a proof of concept and prototype a runtime-as-a-service (RaaS). This cloud based runtime will allow clients to dynamically offload tasks or create cloud applications. Currently software-as-a-service (SaaS) cloud applications are purpose built and have a predefined scope in which they can assist or serve the client; this scope cannot be changed without physical alteration to the client and server software. With RaaS the client potentially could define any task it wanted at any time depending on its environment variables, the client and server would then communicate parameters and returns for that task. For the client to utilize a RaaS it must be able to conceive and then define a task using an appropriate XML vocabulary. As the scope of the cloud solution is defined by the client at its runtime, the cloud solution only has to exist for as long as the client requires it to as opposed to a client using a dedicated service. Deliverables The crux of the project will require an XML vocabulary in which the client and server will communicate. I’ll prototype the server application that will dynamically create and manage cloud solutions. The solution will be coded using an interpreted language, such as python or javascript, which can evaluate expressions in runtime or a language that can dynamically compile such as C# or Java. As a further proof of concept I will also produce a mock client that offloads tasks to the server. The report will attempt to explain the different flavours of cloud computing solutions including infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and SaaS including real world examples and where the use of a RaaS could have improved the overall example solution. Disclaimer: I'm not requesting stakeholders in my project nor am I delegating work. Any materials other than feedback, advice or directions will not be utilized.

• Scale DIV with tiles

  - by user15350

  I am trying to create a repeating background. I have a main DIV with a grid of small 16x16 DIVs. I am trying to scale the main DIV in CSS; when the small DIVs simply have a red background color everything works great, but when there is a background image in the small DIVs then borders become visible between the tiles. This image explains the problem: http://cl.ly/FpNW/o Check the HTML in these examples: With BG-COLOR: http://jsfiddle.net/pTLXw/ With BG-IMG: http://jsfiddle.net/vkpuY/ Does anyone know what is causing this problem and how to fix it? If it is not possible to fix while using DIV, is there another way to do this? Thanks you so much!

• What web oriented language would work best with binary data?

  - by Qqwy

  I want to create a service where people can upload files. However, since file storage costs money, I want to compress the files so they take less space. I would want to write my own compression algorithm, however, PHP doesn't have good ways to handle binary data (which is needed for many compression algorithms). So I wondered, what would be a better language to create such a website in? I have knowledge of PHP (and Javascript, HTML and CSS) but no experience with other things like Ruby, Perl, Python, and other web development languages.

• What do you need to know to get a job as a web developer [closed]

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.

• How can I view localized versions of my site?

  - by Max Vernon

  We are adding internationalization to our site. We are getting the client's IP address from the headers and looking it up against the IP2location database to get the client's country. Several of our clients reported seeing a blank page over the weekend. We'd like to be able to get screenshots or use a browser from many different countries on an ongoing basis for testing code changes. I need to know what the site looks like when accessed from various countries since there are several elements that vary by country. I've used Tor and Vidalia, along with the Tor customized Firefox browser however it appears the CSS is getting mangled. I have also used http://webpagetest.org to check the site, however the screenshot it gives is too small to be really useful. Is there a site or a service I can use to get screenshots or interact with my website from various countries?

• What undergraduate course to choose for a mature programmer returning to study

  - by Dve

  I have been developing applications (mostly web-based) for almost 10 years now and have learnt pretty much everything I know through experience (and the internet!). I wouldn't call myself an advanced programmer, but I am quite proficient in several languages (C#, Javascript, Ruby, HTML/CSS etc) and spend a quite a bit of time working on personal projects and reading countless books & articles. I am looking to emigrate to Canada, hopefully Vancouver (im from the UK) and one way would be on a student visa, if I was going to be studying for a minimum of 2 years. Having never been to university or achieved anything higher than A-Levels I am quite tempted by this path. The thought of learning is more exciting to me now than it was 10 years ago! What would be people recommend as a good undergraduate course to take that would complement this career path? Would Math be beneficial, if so which area of Math? TL;DR What undergraduate course/area of study would complement 10 years of (mostly web-based) programming experience?

• brackets in php templates

  - by Othman

  I have a script, and now it's the perfect time to have an option to change theme templates. I was looking forward to store these files in php files, or html files. with CSS file. I looked over some codes and I found that they use brackets to refer to the variable. Here's an example of a template block: <div class='block_div'> <center>{title}</center> {content} </div> I know that I can use PHP vars usering <?=$var;?>. However, I think the one above is better, and I looked over the web to find anything about it but I couldn't. My Question is how I can use these brackets in my php or html code. to let the user changing the template only not the code!

• Gzip compress offline?

  - by shoosh

  I've configured my site to serve compressed content by putting this line in .htaccess AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript text/css application/javascript application/json This works perfectly for almost all files except a few large JSON files that are above 200Kb. For some reason they are not being compressed. I see that they don't using the net tab in firebug and the Network section in chrome. So as a workaround I thought I could compress these files offline and have Apache read them compressed. What tool should I use to compress them? is the linux gzip the one? any special flags or something I should use? What should I put in .htaccess so that the server would know to serve these files with content-encoding gzip ?

• What are good JS libraries for game dev? (HTML5)

  - by acidzombie24

  If i decide to write a simple game both text and graphical (2d) what libs may i use? Assuming we are using a HTML5 compatible browser. The main things i can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but i am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (i know this exist but i dont know how easy it is to setup or use. But this isnt important to me. Its for the question).

• Final Year Project Advice: what impact on my CV [closed]

  - by Devon Smith

  I am being offered - as a final year project - to do a Company Website. This is basically an out-house project and I am not completely sure whether I should take it. The requirements are : Company Information User Registration Order placements. The technologies that I should use are PHP, Javascript, HTML, CSS and maybe Java Servlets. This appears to me a very basic project and I need an opinion as to what effect it might have on my CV. Is it worth to do it? Or should I go into some research project or something that has not been done before?

• Web Development Internship Interview Help

  - by Todd

  Tomorrow morning I'm interviewing for a web development internship position and I'm seeking general advice pertaining to the questions that interviewers might ask, some questions I should ask them during the interview, and any general tips/suggestions that might help. They're looking for someone with knowledge mainly in HTML/CSS, Joomla, MySQL and PHP, all of which I have excluding Joomla (which I'm installing/doing as much research on as possible at the moment) and I was able to provide them a link to a site I'd been paid to build for a small business which they mentioned they were impressed with. I'd like to prepare myself for the interview as much as I possibly can but I'm wondering how much time I should spend rehashing elements of the languages they're looking for, or if it'd be a better use of my time to research their company and figure out how I'd respond to general questions. I feel that perhaps because I showed them a project I've completed that they'll know that I can grasp the technical side of what they're going for... but this is my first internship interview in this field so I'm not exactly sure what to expect. Thanks

• Facial Recognition for Retail

  - by David Dorf

  My son decided to do his science project on how the brain recognizes faces.  Faces are so complicated and important that the brain has a dedicated area for just that purpose.  During our research, we came across some emerging uses for facial recognition in the retail industry. If you believe the movies, recognizing faces as they walk by a camera is easy for computers but that's not the reality.  Huge investments are being made by the U.S. government in this area, with a focus on airport security.  Now, companies like Eye See are leveraging that research for marketing purposes.  They do things like track eyes while viewing newspaper ads to see which ads get more "eye time."  This can help marketers make better placement and color decisions. But what caught my eye (that was too easy) was their new mannequins that watch shoppers.  These mannequins, being tested at European retailers like Benetton, watch shoppers that walk by and identify their gender, race, and age.  This helps the retailer better understand the types of customers being attracted to the outfit on the mannequin.  Of course to be most accurate, the software has pictures of the employees so they can be filtered out.  Since the mannequins are closer to the shoppers and at eye-level, they are more accurate than traditional in-ceiling LP cameras. Marketing agency RedPepper is offering retailers the ability to recognize loyalty shoppers at their doors using Facedeal.  For customers that have opted into the program, when they enter the store their face is recognized and they are checked in.  Then, as a reward, they are sent an offer on their smartphone. It won't be long before retailers begin to listen to shoppers are they walk the aisles, then keywords can be collected and aggregated to give the retailer an idea of what people are saying about their stores and products.  Sentiment analysis based on what's said or even facial expressions can't be far off. Clearly retailers need to be cautions and respect customer privacy.  That's why these technologies are emerging slowly.  But since the next generation of shoppers are less concerned about privacy, I expect these technologies to appear sporadically in the next five years then go mainstream.  Time will tell.

• WebFX: Running JavaFX as web page

  - by Bruno.Borges

  This weekend I wanted to learn JavaFX, so I decided to code an idea I had a few years ago when I first saw JavaFX Script. So I started coding a web browser that runs HTML with the awesome, HTML5 supported WebView. But this browser also offers one extra feature: it loads FXML files as if they were HTML. So instead of defining your web page with HTML and running with WebKit, you can define a web page with FXML+CSS+JS and run as a JavaFX application. The project is called WebFX and already has a prototype on GitHub. I also uploaded a video on YouTube demonstrating the idea. What do you think about using JavaFX in the future for web pages, instead of HTML?

• What is the best practice for website design and markup now that mobile browsers are common?

  - by Jonathan Drain

  Back in 2008, smartphones were a small market and it was commonplace for sites to be designed for a fixed width - say, 900px or 960px - with the page centered if the browser window was larger. Many designers said fluid width was better, but since user screens typically varied between 1024x768 and 1920x1080, fluid width allowed longer line length than is optimal for ease of reading, and so many sites (including Stack Exchange) use fixed width. Now that mobile devices are common, what is the the best approach to support both desktop and mobile browsers? Establish a separate mobile site (e.g: mobile.example.com) Serve a different CSS to mobile devices; if so how? Server-side browser sniffing, or a @media rule? Use Javascript or something to adapt the website dynamically to the client? Should all websites be expected to be responsive? Some kind of fluid layout Something else?

• Matching my skills with Java and Web Programming

  - by John R

  here is my main question: What is the most common way that Java is used in web development? The reason I ask: I am currently in the process of finding my first internship. Every employer has a separate set of languages, technologies and acronyms they want their candidates to know. In school I did well with Java. As a hobby and interest I have developed a handful of web pages widgets, scripts, etc. My university emphasized Java, C and theory. My hobbies emphasize HTML, PHP, JavaScript, CSS, and a little jQuery, etc. I can't learn a dozen different technologies to satisfy most prospective employers (in what is left of the summer). I think my best bet is combine my skills with Java and my interests in web development. That brings me back to my original question: What is the most common way that Java is used in web development?
