  • 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 an outdated book to learn from?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?

  • Integrated ads in phone apps - how to avoid wasting battery?

    - by Jarede
    Considering the PCWorld review that came out in March: Free Android Apps Packed with Ads are Major Battery Drains ...Researchers from Purdue University in collaboration with Microsoft claim that third-party advertising in free smartphone apps can be responsible for as much as 65 percent to 75 percent of an app's energy consumption... Is there a best practice for integrating advert support into mobile applications, so as to not drain user battery too much? ...When you fire up Angry Birds on your Android phone, the researchers found that the core gaming component only consumes about 18 percent of total app energy. The biggest battery suck comes from the software powering third-party ads and analytics accounting for 45 percent of total app energy, according to the study... Has anyone invoked better ways of keeping away from the "3G Tail", as the report puts it? Is it better/possible to download a large set of adverts that are cached for a few hours, and using them to populate your ad space, to avoid constant use of the Wi-Fi/3G radios? Are there any best practices for the inclusion of adverts in mobile apps?

  • Dependency Injection Confusion

    - by James
    I think I have a decent grasp of what Dependency Inversion principle (DIP) is, my confusion is more around dependency injection. My understanding is the whole point of DI is to decouple parts of an application, to allow changes in one part without effecting another, assuming the interface does not change. For examples sake, we have this public class MyClass(IMyInterface interface) { public MyClass { interface.DoSomething(); } } public interface IMyInterface { void DoSomething(); } How is this var iocContainer = new UnityContainer(); iocContainer.Resolve<MyClass>(); better practice than doing this //if multiple implementations are possible, could use a factory here. IMyInterface interface = new InterfaceImplementation(); var myClass = new MyClass(interface); It may be I am missing a very important point, but I am failing to see what is gained. I am aware that using an IOC container I can easily handle an objects life cycle, which is a +1 but I don't think that is core to what IOC is about.

  • Is hierarchical product backlog a good idea in TFS 2012-2013?

    - by Matías Fidemraizer
    I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.

  • Can it be useful to build an application starting with the GUI?

    - by Grant Palin
    The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

  • Should all, none, or some overridden methods call Super?

    - by JoJo
    When designing a class, how do you decide when all overridden methods should call super or when none of the overridden methods should call super? Also, is it considered bad practice if your code logic requires a mixture of supered and non-supered methods like the Javascript example below? ChildClass = new Class.create(ParentClass, { /** * @Override */ initialize: function($super) { $super(); this.foo = 99; }, /** * @Override */ methodOne: function($super) { $super(); this.foo++; }, /** * @Override */ methodTwo: function($super) { this.foo--; } }); After delving into the iPhone and Android SDKs, I noticed that super must be called on every overridden method, or else the program will crash because something wouldn't get initialized. When deriving from a template/delegate, none of the methods are supered (obviously). So what exactly are these "je ne sais quoi" qualities that determine whether a all, none, or some overriden methods should call super?

  • today's multi-device world for web development

    - by paul smith
    With the huge explosion of mobile devices and addition of HTML5/CSS3, there seems to be a shift towards "responsive" designs (i.e., adapting to smaller screen sizes) which seems to be achieved using CSS3's Media Queries. My question is, given the current need of adapting to both desktop and mobile, is it common practice to actually organize two versions of your website (one for desktop and one for mobile)? Or is there just one version with different css files for targeting different devices and screens? Handling just cross-browser (ie6, ff3, opera9, etc...) HTML4/5, CSS2/3 was already hard enough, but now we're expected to handle cross-device (phone, tablet, etc...) as well, so my assumption is company's would create a separate project for mobile and redirect based on the user agent, but this is just a guess.

  • 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?

  • Displaying and updating score in Android (OpenGL ES 2)

    - by user16547
    I'm using a FrameLayout where I have a GLSurfaceView at the bottom and a few Views on top of it. One of those Views is a TextView that displays the current score. Here's how I'm updating the score TextView based on what happens in my game loop: whenever an event happens that increases the score, I call activity.runOnUiThread(updater), where activity is the activity that has the above FrameLayout (my main game activity) and updater is just a Runnable that increments the score. From my understanding, using runOnUiThread() from the OpenGL thread is standard practice - otherwise you'll get an exception, I can't remember its name. The problem is that there's a very noticeable lag between the event and the score update. For example the character gets a coin, but the coin count is not updated quickly. I tried summing all the score events from my game loop and calling runOnUiThread() only once per loop, but it doesn't seem to make much of a difference - the lag is still noticeable. How can I improve my design to avoid this lag?

  • Coordinating team code review sessions [closed]

    - by Wade Tandy
    My question has two parts: 1) In your team or organization, do you ever do in-person code reviews with all or part of a team, as opposed to online reviews using some sort of tool? 2) How do you structure these meetings? Do you choose to focus on one person's code in a given meeting? Do you look at everything? Take a random sample? Ask people on the team what they'd like to have looked at of theirs? I'd love to add this practice to my development team, so I'd like to hear how others are doing it.

  • How to ramp up my data structures skills after a long hibernation

    - by Anon
    I was pretty good with algorithms and data structures once, a long long time ago. Since then, I programmed professionally, and then went to manage a small team, which totally shot my tech skills in this field back. I've decided I want to be a developer again, and work for Google. The thing is, I'm so out of practice, that if I were to be interviewed right now I would surely flunk out in 10 minutes. What training program would you recommend for me to get back into shape? I already started this weekend by going back to the absolute basics and implementing a few sort algorithms, linked list, and hash table. Next, I think I'll read through the entire course material on the other basic data structures and graph algorithms. I want to find a focused set of practical exercises I can do in a relatively short amount of time, to juggle the old brain cells. I know this stuff - I just need to remind myself that I know it.

  • Should a primary key be immutable?

    - by Vincent Malgrat
    A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

  • Referencing external javascript vs. hosting my own copy

    - by Mr. Jefferson
    Say I have a web app that uses jQuery. Is it better practice to host the necessary javascript files on my own servers along with my website files, or to reference them on jQuery's CDN (example: http://code.jquery.com/jquery-1.7.1.min.js)? I can see pros for both sides: If it's on my servers, that's one less external dependency; if jQuery went down or changed their hosting structure or something like that, then my app breaks. But I feel like that won't happen often; there must be lots of small-time sites doing this, and the jQuery team will want to avoid breaking them. If it's on my servers, that's one less external reference that someone could call a security issue If it's referenced externally, then I don't have to worry about the bandwidth to serve the files (though I know it's not that much). If it's referenced externally and I'm deploying this web site to lots of servers that need to have their own copies of all the files, then it's one less file I have to remember to copy/update.

  • Should functions of a C library always expect a string's length?

    - by Benjamin Kloster
    I'm currently working on a library written in C. Many functions of this library expect a string as char* or const char* in their arguments. I started out with those functions always expecting the string's length as a size_t so that null-termination wasn't required. However, when writing tests, this resulted in frequent use of strlen(), like so: const char* string = "Ugh, strlen is tedious"; libFunction(string, strlen(string)); Trusting the user to pass properly terminated strings would lead to less safe, but more concise and (in my opinion) readable code: libFunction("I hope there's a null-terminator there!"); So, what's the sensible practice here? Make the API more complicated to use, but force the user to think of their input, or document the requirement for a null-terminated string and trust the caller?

  • Hybrid IT or Cloud Initiative – a Perfect Enterprise Architecture Maturation Opportunity

    - by Ted McLaughlan

By this, I mean the EA activities - whether targeted towards compliance, risk mitigation or value opportunity propositions – may not be attached to measurable, active, visible projects that could advance and prove the value of EA. EA doesn’t work by itself, in a vacuum, without collaborative engagement and a means of proving usefulness. A critical vehicle to this proof is successful orchestration and use of assets and investment resources to meet a high-profile business objective – i.e. a successful project. More and more organizations are now exploring and considering some degree of IT outsourcing, buying and using external services and solutions to deliver their IT and business requirements – vs. building and operating in-house, in their own data centers. The rapid growth and success of “Cloud” services makes some decisions easier and some IT projects more successful, while dramatically lowering IT risks and enabling rapid growth. This is particularly true for “Software as a Service” (SaaS) applications, which essentially are complete web applications hosted and delivered over the Internet. Whether SaaS solutions – or any kind of cloud solution - are actually, ultimately the most cost-effective approach truly depends on the organization’s business and IT investment strategy. This leads us to Enterprise Architecture, the connectivity between business strategy and investment objectives, and the capabilities purchased or created to meet them. If an EA framework already exists, the approach to selecting a cloud-based solution and integrating it with internal IT systems (i.e. a “Hybrid IT” solution) is well-served by leveraging EA methods. If an EA framework doesn’t exist, or is simply not mature enough to address complex, integrated IT objectives – a hybrid IT/cloud initiative is the perfect project to advance and prove the value of EA. Why is this? For starters, the success of any complex IT integration project - spanning multiple systems, contracts and organizations, public and private – depends on active collaboration and coordination among the project stakeholders. For a hybrid IT initiative, inclusive of one or more cloud services providers, the IT services, business workflow and data governance challenges alone can be extremely complex, requiring many diverse layers of organizational expertise and authority. Establishing subject matter expertise, authorities and strategic guidance across all the disciplines involved in a hybrid-IT or hybrid-cloud system requires top-level, comprehensive experience and collaborative leadership. Tools and practices reflecting industry expertise and EA alignment can also be very helpful – such as Oracle’s “Cloud Candidate Selection Tool”. Using tools like this, and facilitating this critical collaboration by leading, organizing and coordinating the input and expertise into a shared, referenceable, reusable set of authority models and practices – this is where EA shines, and where Enterprise Architects can be most valuable. The “enterprise”, in this case, becomes something greater than the core organization – it includes internal systems, public cloud services, 3rd-party IT platforms and datacenters, distributed users and devices; a whole greater than the sum of its parts. Through facilitated project collaboration, leading to identification or creation of solid governance models and processes, a durable and useful Enterprise Architecture framework will usually emerge by itself, if not actually identified and managed as such. The transition from planning collaboration to actual coordination, where the program plan, schedule and resources become synchronized and aligned to other investments in the organization portfolio, is where EA methods and artifacts appear and become most useful. The actual scope and use of these artifacts, in the context of this project, can then set the stage for the most desirable, helpful and pragmatic form of the now-maturing EA framework and community of practice. Considering or starting a hybrid-IT or hybrid-cloud initiative? Running into some complex relationship challenges? This is the perfect time to take advantage of your new, growing or possibly latent Enterprise Architecture practice.

  • Online architecture guide

    - by hunterman
    I am a newbie in gamedev, and I don't know about programmer's problems that can appear during development. So can you advice me some best practice for starting build new online multi-player game backend? I just saw reddraft server, and I think Spring library can also do some of its features. What is big difference? Do I need learn more spring or I have to use servers like reddraft or write these tools myself? I know that I need to learn hard and many - and the question is - what I should to learn now at the beginning? Thanks.

  • Tips for managing internal and external links using WordPress [closed]

    - by keruilin
    So I'm looking for ways to optimize my site for user and search engine purposes. I've read several articles and looked at several different plugins. To say the least, I'm thoroughly confused as what are the best practices for managing internal and external links. Here is a list of some of my questions: Which internal links should be set to "nofollow"? Which external links should be set to "nofollow"? To what degree does actively managing links contribute to your PR? Should you use "nofollow" blindly on all links in comments? If a link to an external site is broken (404 or whatever), should you "nofollow" that link? What about "noindex"? As you can see, lots of questions. I'm hoping that you experienced webmasters can give a newb some best-practice advice.

  • What standard superseded 830-1998?

    - by user1564158
    I have been looking into how to document software projects more formally, and I have learned about IEEE 830-1998: Recommended Practice for Software Requirements Specifications. However, as you can see from that link, it has been superseded. I know that 830-1998, and probably even 830-1993, are probably just fine for use. However, if nothing else, I would like to know what standard has superseded it. In this case it may not matter, but if other standards are superseded for more technical things, I think it would be a good idea to link somewhere what standard superseded another (if it is not another one in the same line (830, in this case)). It is worth mentioning that: The most recent standard when searching for "Software Requirements Specifications" or "Software Requirements" on the IEEE Standards Association website is 830-1993, The 2004 (current) version of SWEBOK references 830-1993 (paragraph 2.5), The document's Wikipedia article doesn't mention that the standard was superseded. TLDR: How do you find what standard superseded another, and which one took 830-1998's place?

  • Does Agile (scrum) require one server environment?

    - by Matt W
    Is it necessary/recommend/best practice/any other positive to use only one server environment to perform all development, unit testing and QA? If so, is it then wise/part of Agile to then have only one staging environment before Live? Considering that this could mean internationally distributed teams of developers and testers in different time zones is this wise? This is something being implemented by our QA manager. The opinion put forward is that doing all the dev and testing on a single server is "Agile." The staging environment would be a second environment, and then live.

  • How do I analyze vague Google Analytics data re traffic from Facebook?

    - by user6982
    We have one Facebook fan page and two personal profiles that could be sending traffic and then there are the many facebook pages of friends etc. I am also running an ad campaign from my FB account for my husband's business which has a link from his personal FB profile and his fan page. On Google analytics for his business we get the following referring sites from Facebook: /ajax/emu/end.php which is listed under facebook.com / referral /l.php (which is a not-found page at FB /ajax/emu/end.php which is listed under apps.facebook.com Both of the working links send me to the home page of my profile, which is the account I am working from to create and review the FB ad campaign that we are running. Is this info telling me any useful information at all? Is there a best practice for tracking and analyzing Facebook traffic that is a lot more granular? thanks!

  • Tab navigation and double content

    - by Guisasso
    I have a website in which i use tabs to navigate between pages. For example, page a displays A as an active tab and B and C background tabs. If the visitor gets to the website via page B, i also would like to display to page d, but not a and c. Question: I know i can just create index2 for b for example, so when the visitor gets to b from a, i display a,b,c and index1 when visitor gets to b from d for example. Is that a bad practice? I know double content isn't good, but in which other way can i or should i approach this problem? The tab navigation i designed uses < li and id tag do display active tab, defined in the < body tag.

  • How to detect whether an Object came to sleep at a specific position?

    - by Nils Riedemann
    I'm currently writing a small game with box2dweb and I need some direction for this: I'm throwing a Box and have to hit a specific place and trigger an event when the object that's been thrown isn't moving anymore, "fell asleep" so to say. What's the proper way / best practice for this? I'm currently thinking of asking the b2World whether an Object is within a specific AABB and then wait a few seconds, check if it's still there and then trigger the event. But this seems to me like the roundabout way and the object might still be moving inside of that AABB and eventually even drop out of the AABB.
