  • Dangerous programming

    - by benhowdle89
    Ok, i'm talking pure software/web, i'm not on about code to power Life Support machines or NASA rockets. In terms of software/web development what is the most dangerous single piece of code someone could put into a program (say if they had a grudge against a client/employee) In PHP, the first thing that comes to mind is some sort of file deletion: function EmptyDir($dir) { $handle=opendir($dir); while (($file = readdir($handle))!==false) { echo "$file <br>"; @unlink($dir.'/'.$file); } closedir($handle); } EmptyDir('images'); Or a PHP script that takes a user's sensitive input and posts it to Google sitemap or something? I hope this doesnt get closed off as subjective as there surely must be a ranking order of dangerous code. So i'm asking for the No.1 spot :) DISCLAIMER: I have no grudges against anyone, just curious for the answer!

  • When do you call yourself a programmer

    - by benhowdle89
    "A programmer, computer programmer or coder is someone who writes computer software" from Wikipedia If you do frontend development using jQuery/CSS/HTML do you call yourself a programmer? If you develop PHP applications that deal with databases, do you call yourself a programmer? Are you only a programmer if you write applications for desktops and mobiles? Is the web a place where the line between developer and programmer stops?

  • POST attack on my website

    - by benhowdle89
    Hi, I have a site (humanisms.co.uk) which incorporates a voting system, ie. user clicks "Up" and it sends a parameter to a PHP script via AJAX, the PHP inserts vote into MYSQL db and the new "Up" vote is sent back to the page to update the vote count. This is working great but i've noticed that the number of votes for one of my questions shot up last night. I viewed my webhosts access logs and saw this line: 108.27.195.232 - - [03/Mar/2011:15:20:18 +0000] "POST /vote.php HTTP/1.1" 200 2 "http://www.humanisms.co.uk/" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.114 Safari/534.16" This is repeated well over 100 times and sometimes more than once a second. Now i know they probably arent sitting there clicking Vote but running some sort of PHP loop? I'm not worried about SQL injection but what can i do to prevent this same IP address from doing this or what can i do in general to avoid this scenario. I should also say that there's no login so anyone can click using the voting system. Thanks

  • Programming Geek's CV Design

    - by benhowdle89
    What is the best practice or advice for a programmer's CV? If I were a graphic designer or more of a web designer as opposed to a programmer, then I'd imagine a CV would have a bit more flourish to it. Yet as a programmer, aren't we judged on not only efficiency and results but also creativity, imagination and initiative? Should this be reflected in a CV? Or is it all about the information, no wishy washy designs in sight? Has anyone experimented with an original alternative to a PDF CV with a template from MS Word or Mac Pages?

  • If Apple made Cars [closed]

    - by benhowdle89
    There was a joke going round a few months(?) ago that if the GM industry kept up with the computer industry that we'd all be better off (in relation to driving and costs). There was also a counter joke that if Microsoft made Cars you would, for example, have to squeeze the wing mirror, honk the horn and move the gearstick the reboot the car (CTRL + ALT + DEL) This got me thinking in terms of Apple's recent iPad 2 release, if Apple made cars what would they be like? What sort of technological advancements would software developers and programmers be able to implement if you built a car in a similar fashion to building an iPhone app. Xcode is you Mechanics garage, as it were. What would a car look like if it was designed by Apple Chief of Design: Jonothan Ive?

  • Does my JavaScript look big in this?

    - by benhowdle89
    As programmers, you have certain curtains to hide behind with your code. With PHP all of your code is server side preprocessed, so this never see's the light of day as far as the user is concerned. If you have maybe rushed through some code for a deadline, as long as it functions correctly then the user never needs to know how many expletives you've inserted into the comments. However with more and more applications being written for the web, with a desktop feel implemented by AJAX and popular frameworks like jQuery being banded around to every Tom, Dick and Harry, how can a programmer maintain some dignity and hide his/her JavaScript code without it being flaunted like dirty laundry when the users hit Right Click-View Source or Inspect Element. Are there any ways to hide JavaScript application logic/code?

  • OOP vs Frameworks (DRY, Organisation, Readability)

    - by benhowdle89
    In terms of organisation, code-readability and DRY programming, which, between OOP and Frameworks shows more of these 3 attributes? I'm aware that inline, procedural coding is viewed by many as a thing of the past, so which is the best route to take for these two? Just to clarify what i mean by OOP and frameworks From Wikipedia: Object-oriented programming (OOP) is a programming paradigm In computer programming, a software framework is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code, thus providing specific functionality

  • How necessary is it to learn JavaScript before jQuery?

    - by benhowdle89
    In my opinion, when I looked at JavaScript, it looked like not my cup of tea. When I came across jQuery, I loved it. I sat and watched Nettuts+ 15 days of jQuery screencasts, 1 year later and now I'm fairly confident I wouldn't develop a website without including jQuery's library. I have never felt this has held me back but my question is, will this come back and bite me in the ass one day, the fact that I didn't have a solid JavaScript foundation before jumping feet first into one of its best (if not the best) frameworks? Did anyone else take this approach?

  • Do backend developers care what their code looks like in the frontend?

    - by benhowdle89
    As a backend and a frontend developer I see the process from start to finish, first by creating the logic, displaying the correct data on a web page and then using frontend skills to make this look awesome. My question is, do pure backend developers care what their code ends up looking like in the frontend? As far as the user is concerned, they will ONLY see design/frontend. They don't actually care that your code is clean, DRY and maintainable. As long as it doesn't disrupt their payment process or flight booking they do not care. Does this affect the average backend developer?

  • How important is to be able to write code like you would write prose

    - by benhowdle89
    Recently I heard of a company that, for interviews, asks potential employees to stand up and write out code on a whiteboard. Apparently that freaked alot of interviewees out. This got me thinking and even though I consider myself a reasonable programmer, I would be hard pressed to write lengthy code out without referring to previous code I had written or doing a quick Google search. How many programmers could safely say "Yes I could write all my code out just like I was writing an email"?

  • Source code not matching uploaded HTML file

    - by benhowdle89
    I'm not sure if this is the right place to ask but i'm having a hugely frustrating problem with Coda and my website (i'm not sure which one is causing the issue) I'm using Coda to make changes to my website, Coda uses built in FTP to save changes to your web page. So when you hit Save, it uploads the new file. I've been using Coda for months and never had a problem until now. I am making changes in the html of my index.php and hitting save, it's successfully uploading the file but no changes are reflected in the source code in ANY browser. I even logged into cPanel on my website, ie. www.example.com:2082 and looked at the file - the changes have been made successfully. But the actual webpage in browser's source code, no changes?? I have tried adding which made no difference. Interestingly i make changes to style.css and the changes are instant. I have emptied the cache on all of my browsers but i'm still having an issue. Does this sound like a Coda problem or has anyone heard of such a thing?

  • text options for seo-minded web developer

    - by benhowdle89
    I've been asked by a client if i could jazz up their tagline on their website i'm developing/designing. I've thought about the options and want to stay as SEO minded as i can but i'm struggling to think of a way i could strike a balance between having a really smart, anti-aliased looking heading at the top of their site under the logo but have it searchable/crawlable by the big G (google). Sifr? Cufon? Images? What do people recommend in terms of SEO and visual niceties?

  • CSS3 new features...whats the point?

    - by benhowdle89
    I've been reading a lot of ways recently of how to avoid having to use Photoshop for things like gradients and shadows on buttons, when you can use CSS3 Box Shadow for such features. Now this is great, but obviously legacy browsers and most IE browsers don't yet implement CSS3 features, so my question is, why save yourself extra work in Photoshop when you can use CSS3 but then HAVE to use Photoshop for other browsers to see the desired effects? Isn't that just extra work?

  • Can this jQuery/Javascript functionality be replicated with PHP

    - by benhowdle89
    This is the code to grab tweets, but i need this in PHP, can anybody offer any insight? $(document).ready( function() { var url = "http://twitter.com/status/user_timeline/joebloggs.json?count=1&callback=?"; $.getJSON(url, function(data){ $.each(data, function(i, item) { $("#twitter-posts").append("<p>" + item.text.linkify() + " <span class='created_at'>" + relative_time(item.created_at) + " via " + item.source + "</span></p>"); }); }); }); String.prototype.linkify = function() { return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/, function(m) { return m.link(m); }); }; function relative_time(time_value) { var values = time_value.split(" "); time_value = values[1] + " " + values[2] + ", " + values[5] + " " + values[3]; var parsed_date = Date.parse(time_value); var relative_to = (arguments.length > 1) ? arguments[1] : new Date(); var delta = parseInt((relative_to.getTime() - parsed_date) / 1000); delta = delta + (relative_to.getTimezoneOffset() * 60); var r = ''; if (delta < 60) { r = 'a minute ago'; } else if(delta < 120) { r = 'couple of minutes ago'; } else if(delta < (45*60)) { r = (parseInt(delta / 60)).toString() + ' minutes ago'; } else if(delta < (90*60)) { r = 'an hour ago'; } else if(delta < (24*60*60)) { r = '' + (parseInt(delta / 3600)).toString() + ' hours ago'; } else if(delta < (48*60*60)) { r = '1 day ago'; } else { r = (parseInt(delta / 86400)).toString() + ' days ago'; } return r; } function twitter_callback () { return true; }

  • jQuery check on wordchange rather than "change" trigger

    - by benhowdle89
    I have a input that the user types a search parameter into, at the moment i have it on keyup to do a POST ajax request to a PHP script that returns search results. however its firing off 50 billion (not literally) post requests in about 10 seconds (as the user types) which slows the whole experience down. Can i use jQuery to detect a "wordup" rather than "keyup" by detecting the use of the space bar? Does this make sense?

  • How important is caching for a site's speed with PHP?

    - by benhowdle89
    I've just made a user-content orientated website http://www.humanisms.co.uk Its done in PHP, MySQL and jQuery's AJAX, at the moment there is only a dozen or so submissions and already i can feel it lagging slightly when it goes to a new page (therefore running a new mysql query) Is it most important for me to try and optimise my mysql queries (by prepared statements) or is it worth in looking at CDN's (amazon s3) and caching (much like the WordPress plugin WP Super Cache) which works by serving static HTML files when there hasnt been new content submitted. Which route is the most beneficial, for me as a developer, to take, ie. where am i better off concentrating my efforts to speed up the site?

  • PHP GET issue - it aint workin!

    - by benhowdle89
    I have a simple PHP form which displays inputs with values from a mysql DB and send the form results to another page which updates a db table based on the GET results: echo "<form method='get' action='updateprojects.php'>"; echo "<table>"; echo "<tr>"; echo " <th>Project No</th> <th>Customer Name</th> <th>Description</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td><input value=" . $row['project_no'] . "></input></td>"; echo "<td><input value='" . $row['cust_name'] . "'></input></td>"; echo "<td><input value='" . $row['description'] . "'></input></td>"; echo "</tr>"; } echo "</table>"; echo "<input type='submit' value='Update' />"; echo "</form>"; on updateprojects.php i have set up the GET variable and even echoed them to check but nothing comes through! Cannot see why!? This is the start of updateprojects.php: echo $_GET['project_no'].$_GET['cust_name'].$_GET['description'];

  • multiple return values from PHP with jQuery AJAX

    I'm using this jQuery code: $.ajax ({ type: "POST", url: "customerfilter.php", data: dataString, cache: false, success: function(html) { $(".custName").html(html); } }); How can i do something like this: $(".projDesc").html(html1); So i can split the returned results into two html elements? echo "<p>" .$row['cust_name']. "</p>"; thats the PHP i'm using and i want to echo another statement which i can put into another HTML element Does this make sense?
