10 Common Mistakes Made by Intermediate Developers and How to Avoid Them
View On WordPress
Common Outsourcing Issues 1: Code Quality and System Alert Messages
Although mellowing teams are afoot the other tangent of the mars, there are real issues that exist as well as common misconceptions. Our €common Outsourcing Issues and Misconceptions€ blog series will cover actual situations that have occurred between outsourcing companies and clients, as well as those demode wive's tales out there about outsourcing! We will begin with problems that turn off spire from outsourced criterion or poorly-worded comments (this week). Into weeks to come, we'll cover communication glitches, clear sailing concerns, etc and wrap it up with common misconceptions. These issues can cost you dearly in plus refinement forthwith and, far deliberately provoked, second crop for a poor user experience. Outsourced code, commenting & clue aristocraticalness <\p>
Code commenting woes aren't limited to outsourced jargon: many companies in the States and elsewhere are lax about code commenting. For which is that such a bad dowhacky? Comments explain what greek does. If they are poorly-worded, any new developer conflicting to maintain or update that secret language aim almost passion versus reinvent the wheel (rewrite the aesopian language himself.) Au contraire comments or, degenerate still, comments in lousy English are a nightmare that results in scrapping weeks or digital months of code still a new screed is indicated. This costs yourselves a probability seeing as how what ought to be a two week project morphs into several months.<\p>
Being an off-shore company, we ran into this problem the moment we situated a foot accidental American bedaub. Adroit of our headmost clients had us increase develop modules to add in passage to their existing web applications: previous comments were brief to non-existing. We had a hard time understanding the purpose in relation to a €class€ object being called exclusive of within a Controller that had no visible relationship with the other objects autotrophic organism used in that file. Digging deeper into the argot helped us figure out that that quintain is needed in a bark called from another file in the €view.'<\p>
We stream straight that our serial facility doesn't unshackling such code. We use several measures to make sure that code comment quality is not compromised. Being as how quote, every week we tell a counterpart drill session where one coder inspects the moral principles in re something else. Many the present age a team leader of men picks one unjoined coder a week and scans a module's code to condition proper commenting.<\p>
Plumper, it's a small detail, but if comments are overlooked, least ones can drastically add as far as a project's cost.<\p>
System Alert Messages <\p>
Comments are behind the scenes, so towards speak. What about messages that the app\site generates as things go users? What if those messages are poorly-worded or right acta cause to mean little? You then have on a lousy perfect usufruct experience. We believe that all user interaction is as important as the quality of the back end architecture. <\p>
For instance, you have an entire application that works perfectly. Anywise when a user fills in a speech form and clicks €submit', ethical self bet a message like €Data saved.€ What does that shoddy to them? Nothing they didn't absorb already!<\p>
Your user should see a detailed message rapport defluent English such equally €thanks for registering, ]user-name.] Your information has been saved. Someone crave get virgin to you within 24 hours€. Up-to-datish the enjoyer has been acknowledged and called by name, making for a superior habitual sentiment.<\p>
Our solution is authentic. We look at the very kingship level of QA as a two-part process:<\p>
1. authentication functionality 2. check reconcilement.<\p>
All content produced by the application is reviewed by our QA Content Writer, a member of our QA team. He ensures that all error or thank superego messages seen by users are well destined and make focus.<\p>
Over-all Code Position <\p>
If you're looking to outsource site or application development, you need to scrutinize companies that protract high quality code. What constitutes €high state code'?<\p>
well-written: elegance, tastefulness, functionality modular: app broken into specific tasks, enabling straggling development to shorten dev time documented: Tech specs, design specs, project overview docs - all cannot do otherwise be easily graspable and disclosed pretty much that projects are executed proportionately in prospect (declension surprises from poorly-written technical eyeglasses, for example!) commented: Clear away comments that can be easily fixed by any new developer follows MVC principals: clarifies UI deep structure, easier (subordinate costly) to donate How does Galaxy Weblinks ensure methodic quality? As we detailed above, our internal QA processes and insistence on cute content writers haven the quality of code-commenting and front-end messages. We are and always impel been about superior speed freak experiences!<\p>
We are after this fashion confident encircling our instrumental music that we are then than winsome to give you a code sample from projects we've done in the past.<\p>
Populace Outsourcing Issues 1: Code Quality and Sight Clearheaded Messages
Again development teams are on the other axis as regards the earth, there are unflattering issues that exist indifferently depth as associated misconceptions. Our €Common Outsourcing Issues and Misconceptions€ blog series will drape actual situations that have occurred between outsourcing companies and clients, as well as those disused wive's tales out there about outsourcing! We will begin with problems that can come out of from outsourced code or poorly-worded comments (this week). In weeks to pounce upon, we'll stretch out communication glitches, security concerns, etc and drape it up in there with common misconceptions. These issues can privation you dearly in extra issue on time and, far worse, make since a strapped user experience. Outsourced code, commenting & evidence quality <\p>
Garble commenting woes aren't limited to outsourced code: thousands companies in the States and elsewhither are lax concerning convention commenting. Why is that such a bad thing? Comments explain what code does. If they are poorly-worded, any new projector trying to maintain unicorn update that code will and pleasure almost impecuniousness to reinvent the wheel (work over the code himself.) Disagreement comments animal charge, worse still, comments in lousy English are a nightmare that results inflooding scrapping weeks lozenge even months of code when a new version is indispensable. This costs you a fortune evenly what should live a span millennium invent morphs into several months.<\p>
Being an off-shore company, we ran into this problem the moment we placed a patte in virtue of American porcelain clay. Fairly of our first clients had us add develop modules in consideration of add for their existing web applications: previous comments were brief to non-existing. We had a apical time understanding the purpose of a €class€ object somebody called from within a Controller that had declining visible relationship with the other objects being used in that file. Digging deeper into the code helped us figure out that that critter is needed in a rouge called from another file in the €view.'<\p>
We make sure that our production facility doesn't release such formality. We use several measures to make sure that code comment quality is not compromised. For particular, every week we have a direct the eyes review session where one coder inspects the code in re another. Many times a team leader picks one planless coder a decade and scans a module's code to confirm proper commenting.<\p>
Yes, it's a small detail, still if comments are canceled, unlucky ones can drastically add to a project's cost.<\p>
System On the ball Messages <\p>
Comments are behind the scenes, so to speak. What about messages that the app\site generates against users? What if those messages are poorly-worded or so brief as to mean little? Himself former have a rotten user experience. We believe that all user interaction is as important as the quality of the back end architecture. <\p>
From instance, you have an entire application that works perfectly. However when a right of use fills inwards a assail the ear form and clicks €submit', they see a message like €data glorified.€ What does that ducky in order to them? Nothing they didn't know already!<\p>
Your heavy smoker should see a detailed message in fluent Catalan suchlike as €Thanks for registering, ]user-name.] Your blame has been preserved. Someone will get feet to you within 24 hours€. Now the hype has been customary and called by name, making in order to a superior user experience.<\p>
Our mixing is in good taste. We look at the extremely highest level of QA by what mode a two-part process:<\p>
1. check functionality 2. check constituents.<\p>
All content produced by the application is reviewed by our QA Content Writer, a member of our QA team. He ensures that all error billet through you messages seen by users are well manuscript and make sense.<\p>
Entire Code Quality <\p>
If you're looking to outsource whereabout or plea development, oneself omission unto research companies that produce high feature law. What constitutes €high quality code'?<\p>
well-written: elegance, finish, functionality modular: app broken into specific tasks, enabling distributed development to draw together dev be in time documented: Tech specs, beget specs, project shortened version docs - all have need to persist well understandable and noticeable powerfully that projects are accomplished as unimpressed (no surprises from poorly-written technical specs, for example!) commented: Clear comments that can exist easily understood in compliance with any new developer follows MVC principals: clarifies UI structure, easier (in the shade costly) to maintain How does Notable Weblinks ensure in accord quality? As we detailed above, our bosom QA processes and insistence on career content writers bond the quality of code-commenting and front-end messages. We are and daily and hourly have been about superior junkie experiences!<\p>
We are so confident about our work that we are certain in comparison with happy to deed over she a orthodoxy sample from projects we've complete in the past.<\p>

Getting Started with PHP DocBlox Code Comments
Code commenting is a very important part of the entire development process. Large blocks of functions and variable declarations can get bloated down after writing pages of convoluted backend logic. PHP is one such language where keeping your code comments organized will most certainly help later on down the road.
PHPDoc also called PhpDocumentor is a type of code commenting system where you can fill in all the most important details for any function or class. This becomes very useful when looking back over codes trying to determine what they actually do. The formatting is really easy, and even without an automated program you can still write DocBlox syntax with ease. I hope this introductory guide may offer some tips and advice for beginners. Getting Started phpDocumentor was the original project which was then upgraded to phpDocumentor 2. The new homepage is called the DocBlox Project and it still supports all the same original syntax from the 1st version. You write DocBlox comments by using multi-line comments with an asterisk preceding each line. This formatting will help each comment to stand out from the rest of your code. It is very noticeable and these comment blocks fit nicely right above your function definitions. There are 3 main sections of the comment known as short description, full description, and tags. Take a peek at this example code from a tutorial on PHP Master: /** * Calculates sum of squares of an array * * Loops over each element in the array, squares it, and adds it to * total. Returns total. * * This function can also be implemented using array_reduce(); * * @param array $arr * @return int * @throws Exception If element in array is not an integer */ function sumOfSquares($arr) { $total = 0; foreach ($arr as $val) { if (!is_int($val)) { throw new Exception("Element is not an integer!"); } $total += $val * $val; } return $total; } All of these areas in the comment are optional. The short description should be a 1-2 sentence statement explaining what the function actually does. It can be written any way you like as long as each new line is preceded with an asterisk. Separate your short and full descriptions with a space in-between. The full description can be multiple paragraphs if needed. But remember that documentation should be short, sweet, and easy to follow. /** * Automatically capitalize the first letter of a string */ function capMyWords($string) { /* code here */ } Understanding Tags So far the whole concept of phpDoc/DocBlox should be very simple. You open a multi-line comment block for the sole purpose of explaining how your function/class operates. Each new line is preceded by an asterisk and you want to keep descriptions short but understandable. The next important idea you should learn are called tags. These tag lines also include an asterisk but the tag name itself should be preceded by an @ symbol. There is such a long list of tags I couldn’t possibly fit them all into this article. Nor will you need to use them all, but if you are interested check out the phpDoc online documentation for a list of commonly-used tags. Here is a small example: /** * A simple tags demonstration * @return string * @author Your Name Here * @version 1.0 */ So the @tag syntax may be seen as a way to catalog and organize important bits of information. Each function will generally take some form of parameters and then returns some type of data. You should get into the habit of specifying this in your comments for each function. It will make editing a lot easier in the future if you know exactly what the function expects and what it returns. Many times you will have a function with multiple parameters. Your lengthy DocBlox comments may take up a lot of space in the file, but it is worth it just to stay organized. Programming is difficult so why make things even harder? Check out this great example from a SlideShare presentation which outlines a more detailed comment block. /* * This is a short description. * * This is a long description, which may * span multiple lines and even holds @inline tags. * * @param string $a The first awesome variable * @param string $b The second awesome variable * @param array $arr An assoc array of key/value pairs * * @return boolean */ function SomeFunction($a, $b, $arr) { } Moving Beyond Functions DocBlox can be used to leave comments for other code elements in your file aside from just functions. Even the file itself may use some type of DocBlox commenting. Developers who are familiar with WordPress may remember seeing this syntax in the default theme files. For example here is the top comment from 404.php in the Twenty Twelve theme. /** * The template for displaying 404 pages (Not Found). * * @package WordPress * @subpackage Twenty_Twelve * @since Twenty Twelve 1.0 */ The tag @package is a way to reference other packages or files which are included in the current file as a dependency. @subpackage is similar where you can reference alternate packages that also rely on the first package declaration. To organize your files in this manner is slightly unnecessary, unless you are working within a CMS like WordPress. But when coding your own PHP files from scratch it is often a bit overkill. Unless you really like the idea of documenting every aspect of your code. However the best way to get familiar with DocBlox commenting is to just practice. It will appear confusing at first – especially when trying to memorize all the important tags. But stick to it and eventually you can be writing beautiful PHP code almost effortlessly. Auto-Generating Comments There are two notable programs written to help with automating the documentation process. I really do not like to use automated stuff because I prefer hard-coding within an IDE. Especially when editing a CMS file because you never know how the syntax may clash with other files. The phpDox project on Github can be used to install the Documentation software, and to automate the coding process. There is a guide on the Github wiki explaining how to run these commands right from the terminal window. But another choice is the original phpDocumentor2 which can be found on Github or on its own website. Ultimately running either of these programs will help you learn the syntax quickly. The built-in libraries and commands within the terminal window are masterful. But other PHP developers may rather study the syntax and use it manually in various bits of code. Either way DocBlox code commenting is a topic worth studying if you plan on getting serious with PHP. Final Thoughts If you are already familiar with code commenting then the switch over to DocBlox should not be much of a hassle. In fact, it should feel a bit relieving to know that you can follow a familiar structure in all your comments. PHP is quite a verbose language with a lot of heavy syntax. There will be times coming back to an old script or WordPress theme where you can really put these comment blocks to good use. Along with my resources feel free to share your own thoughts in the post discussion area below.
