• Is the copy/paste approach professionally viable when working with the Google Maps API?

  - by Ian Campbell

  I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

• .Net SvcUtil: attributes must be optional

  - by Michel van Engelen

  Hi, I'm trying to generate C# code classes with SvcUtil.exe instead of Xsd.exe. The latter is giving me some problems. Command line: SvcUtil.exe myschema.xsd /dconly /ser:XmlSerializer Several SvcUtil problems are described and solved here: http://blog.shutupandcode.net/?p=761 One problem I can't solve is this one: Error: Type 'DatafieldDescription' in namespace '' cannot be imported. Attributes must be optional and from namespace 'http://schemas.microsoft.com/2003/10/Seri alization/'. Either change the schema so that the types can map to data contract types or use ImportXmlType or use a different serializer. ' I changed <xs:attribute name="Order" use="required"> to <xs:attribute name="Order" use="optional"> and <xs:attribute name="Order"> But the error remains. Is it possible to use attributes, or do I have to delete them all (in that case, this excercition is over)?

• To branch or not to branch?

  - by Idsa

  Till recently my development workflow was the following: Get the feature from product owner Make a branch (if feature is more than 1 day) Implement it in a branch Merge changes from main branch to my branch (to reduce conflicts during backward merging) Merge my branch back to main branch Sometimes there were problems with merging, but in general I liked it. But recently I see more and more followers of idea to not make branches as it makes more difficult to practice continuous integration, continuous delivery, etc. And it sounds especially funny from people with distributed VCS background who were talking so much about great merging implementations of Git, Mercurial, etc. So the question is should we use branches nowadays?

• coding after a couple beers

  - by Patrick

  Sometimes after work I'll come home and have a beer or two and I've found that once I have a beer in me, my desire to code drops precipitously. I'm not talking about getting hammered or anything, but I can't seem to get up the gumption to do any coding. I'm still fine to do other things, i.e.- paying bills, playing games, reading, etc, it's just coding. I know that some people prefer to code with some beer in them. Is this normal, or do I need to practice coding under the influence so if the need ever arises, I'm ready for it. (I will only be coding on pet projects, nothing serious while CUI)

• Architecture: Bringing Value to the Table

  - by Bob Rhubart

  A recent TechTarget article features an interview with Business Architecture expert William Ulrich (Take a business-driven approach to application modernization ). In that article Ulrich offers this advice: "Moving from one technical architecture might be perfectly viable on a project by project basis, but when you're looking at the big picture and you want to really understand how to drive business value so that the business is pushing money into IT instead of IT pulling money back, you have to understand the business architecture. When we do that we're going to really be able to start bringing value to the table." In many respects that big picture view is what software architecture is all about. As an architect, your technical skills must be top-notch. But if you don't apply that technical knowledge within the larger context of moving the business forward, what are you accomplishing? If you're interested in more insight from William Ulrich, you can listen to the ArchBeat Podcast interview he did last year, in which he and co-author Neal McWhorter talked about their book, Business Architecture: The Art and Practice of Business Transformation.

• Getting php tips and tutorials as daily emails to improve the knowledge in php programming

  - by Sourabh

  Hi Thanks for your time. This question is related to php programming but not a programming question.I have a young team of php (LAMP + javascript) programmers.I want them to learn better coding and keep themselves updated with the latest advancements in web domain. I was thinking if there was any web site which send daily emails about php questions / problems/ solutions to common problems/ tips which will practically help the people to spend 10-15 minutes daily and enjoy the learning.This will also kind of automate the habit of self learning on daily basis. There are lots of PHP forums and php tutorials website, I tried to google but I did not find any website which does what I am looking for. Please let me know if you know such website.If you have any other ideas to achieve the goal are also welcome. -Sourabh

• Memory leak with preg_replace

  - by Silvio Donnini

  I'm using the preg_replace function to replace accents in a string, I'm working with UTF-8. I have incurred in what seems to be a memory leak, but I can't isolate the root cause, my code is rather simple: preg_replace( array_keys($aToNoAccents), array_values($aToNoAccents), $sText ); where $aToNoAccents is an associative array with entries like '~[A]~u' => 'A', '~[C]~u' => 'C',. My script prints this error for the above line: Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 3039 bytes) Obviously it's not a matter of increasing the allowed memory for PHP, (a 1Gb footprint is way off the scale of my application). Also, that line is executed thousands of times without problems but, just for some cases which are difficult to reproduce, it yields the error. Is anyone aware of memory problems with preg_replace and UTF-8 strings? Am I to use special care in passing actual parameters to such function? I'm using PHP 5.2.6-3 with Suhosin-Patch thanks Silvio

• Why aren't there automated translators from one programming language to another?

  - by serg

  Most programming languages are Turing complete, which means that any task that can be solved in one language can be solved in another one, or even on Turing machine. Then why aren't there automatic translators that can convert programs from any given language to any other language? I've seen couple attempts for two languages, but they always work only on a limited subset of a language and can hardly be used for converting real projects. Is it possible, at least in theory, to write 100% correct translator between all languages? What are the challenges in practice? Are there any existing translators that work?

• Examples and Best Practices for Seeding Defects?

  - by MathAttack

  Defect Seeding seems to be one of the few ways a development organization can tell how thorough an independent testing group is. I'm a fan of using metrics to help counter overconfidence biases, and drive discussions around facts. With that said, I haven't seen Seeding Defects used in practice. Are there best practices above and beyond what McConnell explained? Are there public examples where this has been done? In the absence of the above, any thoughts on why it hasn't been done more? Thanks in advance!

• How to manage product backlog/user stories

  - by Andrew Stephens

  We're about to start a new project using Agile (using TFS), and I have a couple of "good practice" questions regarding the product backlog:- When we first start adding users stories, is it a good idea to put them in (say) a "Backlog" iteration, or just leave their iteration blank? Obviously when the time comes to start work on a US it would be moved into the appropriate iteration backlog. When breaking an epic down into smaller USs, would I simply close the original epic, as it's no longer required? Or should I create the new USs as children of the epic? (it's then someone's responsibility to close the epic once all child USs have been completed). Lastly, should the product backlog list all USs regardless of status, or only those that have not been started (i.e in my proposed "Backlog" iteration)? I realise these questions aren't life-or-death, but it would be nice to know how other people manage their product backlogs so we can organise things properly from the start.

• Decompressing file with gzip produces file with no read-permissions on Windows 7

  - by Abiel

  I am attempting to decompress a .gz file using the GnuWin32 gzip program in Windows 7. I have full permissions on the compressed file, and my user account is an administrator. However, I end up not having read permissions on the decompressed file. To get read permissions I would have to manually change the permissions on it through right-clicking and selecting Properties Security. I am able to do this exact same thing with no permission problems in Windows XP, which leads me to believe that Windows 7's user account control system is causing problems. Does anyone know what I can do to make things work as I would expect (read permission on the decompressed file) in Windows 7? Thanks.

• HTML5 article tag application for the iPad/iPhone

  - by dspencer

  I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will. Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?

• How does one block unsupported web browsers?

  - by Sn3akyP3t3

  Web browsers with an end of life no longer receive security updates which not only makes them vulnerable to the end user, but I imagine its not safe for the server's which receive visits by them either. Is it practical to block or enforce and notify the end user that their browser is unsafe and unsupported? If so, how would one achieve that? I don't know of any official or crowd-sourced listing with that information to parse and keep up to date. I'm aware that the practice can be custom built with User Agent parsing and feature detection for HTML5 enabled browsers.

• Java web UI framework like ASP.NET MVC?

  - by Ethel Evans

  I'm doing some web apps for personal projects that might be shared out with my friends. I'm trying to use skills that will help me at work, but don't have $$ to spend on Visual Studio right now and don't want to try to cobble something together with Express Editions. Since I've been sort of wanting to bring my Java skills up to date and the main skills I want to work on are design and architecture skills, this isn't a big deal - except that I have no idea how to track down the right UI framework. I know I want something based on MVC, to get more practice with frameworks for that design pattern (we're using ASP .NET MVC2 at work). The UIs that I'll be making will be pretty simple - data entry, buttons, text, images. They will need AJAX. Any thoughts about which frameworks to look at? I'll be watching the comments, if anyone wants additional clarification on what I'm looking for.

• How to handle estimates for programmers joining the team?

  - by Jordan

  Iteration has already started, new programmer joins the team, task X has already been estimated to be 30 hours by a different developer. What is the best practice in this situation? new developer runs with the given estimate (the idea being that any discrepancy will be corrected for when velocity is calculated?) new developer re-estimates task? (if so, what if it's significantly higher and no longer fits in the iteration?) throw our hands up and go back to waterfall? something else entirely?

• What is the state of the art in OOP?

  - by Ollie Saunders

  I used to do a lot of object-oriented programming and found myself reading up a lot on how to do it well. When C++ was the dominant OOP language there was a very different set of best practices than have emerged since. Some of the newer ideas I know of are BDD, internal DSLs, and the importing of ideas from functional programming. My question is: is there any consensus on the best way to develop object-oriented software today in the more modern languages such as C#, Ruby, and Python? And what are those practices? For instance, I rather like the idea of stateless objects but how many are actually using that in practice? Or, is the state of the art to deemphasize the importance of OOP? This might be the case for some Python programmers but would be difficult for Rubyists.

• Outlook Macro not executing

  - by Tim

  Hello all, we are using an an outlook macro for incoming emails to unzip the attachments, log them in sql server and copy them to a special working folder where a windows service processes them. The problems are: the user must be logged in at the server otherwise the macro wont run. I think there is no workaround for this. whenever a modal dialog pops up in outlook and waits for user input, the macro wont execute either (f.e. AutoArchive) I have stopped AutoArchiving all x-days in the options. Because its a productive environment, are there other possible windows preventing the macro to execute, which i must disable now? Our outlook-macro solution surely is not the best because of above problems. Are there better alternatives to read emails, unzip attachments and move them to a working folder? My language is VB.Net and server OS is windows 2008. Regards, Tim

• Dependency injection and IOC containers in a closed project

  - by Puckl

  Does it make sense to assemble my project with dependency injection containers if I am the only one who will use the code of that project? The question came up when I read this IOC Article http://martinfowler.com/articles/injection.html The justification for using dependency injection in this article is that friends can reuse a class, and replace depending classes with their own classes because they get injected and not instantiated in the class. I would only use it to inject objects where they are needed instead of passing them through layers to their target. (Which is not so bad I learned here: Is it bad practice to pass instances through several layers?) (Maybe I will reuse parts of the project, who knows, but I don´t know if that is a good justification)

• Which tips helped you learn touch-typing? [closed]

  - by julien

  I've been learning touch-typing for about two weeks now, and I'm really commited to mastering this skill. Eventhough I'm doing ok with prose already, I'm struggling with programming syntax and even more with keybindings. Those stray you away from the home row more than regular words, and aren't as easy to practice. So I often hunt and peck in order to just get it out, but when reverting to old habits like this, I find it hard to get back into the touch-typing mindframe quickly. One little trick that has helped me so far when getting lost is to reposition every finger on its home row key, and mentally visualize the layout bias of the keyboard, ie the backslash kind of alignment of key columns. It's hard to describe though and probably a bit weird... Hope you guys have better tips !

• Does using structure data semantic LocalBusiness schema markup work for local EMD URL's?

  - by ElHaix

  Based on what I have read about Google's recent Panda and Penguin updates, I'm getting the impression that using semantic markup may help improve SEO results. On a EMD (exact match domain) site, that may have been hit, we list location-based products. We are now going to be adding a itemtype="http://schema.org/Product" to each product, with relevant details. However, that product may be available in Los Angeles and also in appear in a Seattle results page. We could add a LocalBusiness item type on each geo page to define the geo location for that page. While the definition states: A particular physical business or branch of an organization. Examples of LocalBusiness include a restaurant, a particular branch of a restaurant chain, a branch of a bank, a medical practice, a club, a bowling alley, etc. We could add use the location property which would simply include the city/state details. I realize that this looks like it is meant for a physical location, however could this be done without seeming black-hat?

• Graphics/Bitmap Limits?

  - by Dean

  Im having some weird problems with Graphics and Bitmap. I have a Graphics Object that is displayed on a PictureBox and im capturing the MouseMove and MouseClick Events that give X and Y Position of the Mouse on the Image but if the Y Position goes Bigger then 32775 it then goes into Negatives which means everything breaks. And if the Image is Bigger then 65535 it then stops displaying the Image. Any Ideas how these problems can be fixed? Thanks Example Code: http://pastebin.com/YEX0XD1q Just Click Make 10,000 Bigger about 4 times then scroll down and on the right it will show the mouse X and Y position and as you move down through the image and hover over the Red Area if you go down enough it will go into Negative Y.

• How do I calculate a SWAP partition?

  - by Dean Howell

  Since the late 90s I've always understood that it is best practice to allocate twice the amount of physical RAM as swap space. I just received my new laptop in the mail and it came with 6GB of RAM. In a separate order I had 16GB of RAM to replace the preinstalled. I didn't have the right torx driver to get to the RAM in this machine, so I installed Ubuntu and manually set a 16GB partition for swap. 32GB seemed a tad excessive... Did I make the right choice? Would my machine perform better if there was no SWAP at all?
