• Best social networking places for programmers.

  - by Chevex

  I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow and related sites but they are more technical and don't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

• Working with Sub-Optimal Disk Configurations (Making the best of what you’ve got)

  - by Jonathan Kehayias

  This is the first post in a what will be a series of posts on working with a sub-optimal disk configuration to squeeze as much performance out of it as possible.  You might ask what a Sub-Optimal Disk Configuration?  In this case it is a Dell Powervault MD3000 with 15 Seagate Barracuda ES.2 SAS 1 TB 7.2K RPM disks (Model Number ST31000640SS).  This equates to just under 14TB of raw storage that can configured into a number of RAID configurations.  In this case, the disk array...(read more)

• Best Practices To Build a Product Registration System?

  - by Volomike

  What are some practices I should use in a product registration system I'm building? I likely can't stop all malicious hacking, but I'd like to slow them down a great deal. (Note, I know only PHP.) I'm talking about things like encrypting traffic, testing the encryption from hacking like a man-in-the-middle attack, etc. The other concern I have is that this needs to work on most PHP5-based web hosting environments, which may not have mcrypt installed.

• Perforce: Best diff editor on Linux ?

  - by shan23

  I'm looking for a Linux based diff viewer/editor for Perforce, which would allow me to retain my VIM editing shortcuts, at the same time having the navigational advantages of a diff editor (goto next/previous edit, view old and new side by side). I have a very good Windows diff viewer(BC3), so please don't suggest anything for Windows. If that editor doesn't require X server (i.e it can be used from cmd line in a putty session), that would be ideal !!

• What is good practice in .NET system architecture design concerning multiple models and aggregates

  - by BuzzBubba

  I'm designing a larger enterprise architecture and I'm in a doubt about how to separate the models and design those. There are several points I'd like suggestions for: - models to define - way to define models Currently my idea is to define: Core (domain) model Repositories to get data to that domain model from a database or other store Business logic model that would contain business logic, validation logic and more specific versions of forms of data retrieval methods View models prepared for specifically formated data output that would be parsed by views of different kind (web, silverlight, etc). For the first model I'm puzzled at what to use and how to define the mode. Should this model entities contain collections and in what form? IList, IEnumerable or IQueryable collections? - I'm thinking of immutable collections which IEnumerable is, but I'd like to avoid huge data collections and to offer my Business logic layer access with LINQ expressions so that query trees get executed at Data level and retrieve only really required data for situations like the one when I'm retrieving a very specific subset of elements amongst thousands or hundreds of thousands. What if I have an item with several thousands of bids? I can't just make an IEnumerable collection of those on the model and then retrieve an item list in some Repository method or even Business model method. Should it be IQueryable so that I actually pass my queries to Repository all the way from the Business logic model layer? Should I just avoid collections in my domain model? Should I void only some collections? Should I separate Domain model and BusinessLogic model or integrate those? Data would be dealt trough repositories which would use Domain model classes. Should repositories be used directly using only classes from domain model like data containers? This is an example of what I had in mind: So, my Domain objects would look like (e.g.) public class Item { public string ItemName { get; set; } public int Price { get; set; } public bool Available { get; set; } private IList<Bid> _bids; public IQueryable<Bid> Bids { get { return _bids.AsQueryable(); } private set { _bids = value; } } public AddNewBid(Bid newBid) { _bids.Add(new Bid {.... } } Where Bid would be defined as a normal class. Repositories would be defined as data retrieval factories and used to get data into another (Business logic) model which would again be used to get data to ViewModels which would then be rendered by different consumers. I would define IQueryable interfaces for all aggregating collections to get flexibility and minimize data retrieved from real data store. Or should I make Domain Model "anemic" with pure data store entities and all collections define for business logic model? One of the most important questions is, where to have IQueryable typed collections? - All the way from Repositories to Business model or not at all and expose only solid IList and IEnumerable from Repositories and deal with more specific queries inside Business model, but have more finer grained methods for data retrieval within Repositories. So, what do you think? Have any suggestions?

• Git branching and tagging best practices

  - by Code-Guru

  I am currently learning to use Git by reading Pro Git. Right now I'm learning about branching and tags. My question is when should I use a branch and when should I use a tag? For example, say I create a branch for version 1.1 of a project. When I finish and release this version, should I leave the branch to mark the release version? Or should I add a tag? If I add a tag, should I delete the version branch (assuming that it is merged into master or some other branch)?

• Break nested loop in Django views.py with a function

  - by knuckfubuck

  I have a nested loop that I would like to break out of. After searching this site it seems the best practice is to put the nested loop into a function and use return to break out of it. Is it acceptable to have functions inside the views.py file that are not a view? What is the best practice for the location of this function? Here's the example code from inside my views.py @login_required def save_bookmark(request): if request.method == 'POST': form = BookmarkSaveForm(request.POST) if form.is_valid(): bookmark_list = Bookmark.objects.all() for bookmark in bookmark_list: for link in bookmark.link_set.all(): if link.url == form.cleaned_data['url']: # Do something. break else: # Do something else. else: form = BookmarkSaveForm() return render_to_response('save_bookmark_form.html', {'form': form})

• best practice for directory polling

  - by Hieu Lam

  Hi all, I have to do batch processing to automate business process. I have to poll directory at regular interval to detect new files and do processing. While old files is being processed, new files can come in. For now, I use quartz scheduler and thread synchronization to ensure that only one thread can process files. Part of the code are: application-context.xml <bean id="methodInvokingJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" <property name="targetObject" ref="documentProcessor" / <property name="targetMethod" value="processDocuments" / </bean DocumentProcessor ..... public void processDocuments() { LOG.info(Thread.currentThread().getName() + " attempt to run."); if (!processing) { synchronized (this) { try { processing = true; LOG.info(Thread.currentThread().getName() + " is processing"); List xmlDocuments = documentManager.getFileNamesFromFolder(incomingFolderPath); // loop over the files and processed unlock files. for (String xmlDocument : xmlDocuments) { processDocument(xmlDocument); } } finally { processing = false; } } } } For the current code, I have to prevent other thread to process files when one thread is processing. Is that a good idea ? or we support multi-threaded processing. In that case how can I know which files is being process and which files has just arrived ? Any idea is really appreciated.

• Best in-memory cache of DB objects for Silverlight [closed]

  - by Jon

  Hi, I'd like to set up a cache of database objects (i.e. rows in a table) in memory in silverlight, which I'll do using WCF and linq-to-sql. Once I have the objects in memory, I'm planning on using MSMQ to receive new objects whenever they have been modified. It's a somewhat complex approach but the goal is to reduce trips to the database and allow instant data communication between Silverlight applications that are connected to the MSMQ. My Silverlight applications are meant to be long-running and the amount of data to be cached will not be large. I'm planning on saving the in-memory cache using local storage. Anyway, in order to process the updated objects that come in, I'd like to know if the user has changed the existing object. Could I use some event relating to data-binding to set a flag indicating that the object has changes? Maybe there's a better way to do the cache entirely? Thanks!

• Bad Practice requiring file within a model?

  - by Lee Marshall

  I have built an MVC php application and was wondering, if instead of having to write out a large amount of html and set the data, could I not just have all this html (with some php) in a separate file and just require it? For example: $test = '<div> Test content <div>More content</div> </div>'; $APP->Template->setData('test', $test, FALSE); Instead could I not just use: $test = require("includes/content.php"); $APP->Template->setData('test', $test, FALSE); Would this be considered as bad practise? It just seems that by requiring files, it can shorten the length of controllers. Would be good to get anybodies advice on this matter.

• What's best practice to check if an object is part of a ManyToMany relationship in Django

  - by PhilGo20

  from an instance of Site with a ManyToMany relationship to Kiosk, i'd like to check if a Kiosk object is part of the relationship. I could do self.apps.get(id=app_id).exists() and check if True or self.apps.get(id=app_id) and catch the ObjectDoesNotExist error or self.apps.filter(id=app_id) and check if True If I have to catch a possible ObjectDoesNotExist error, I may as well use the second one I can do the second but doesnt seem super clean can use the third one but using filter on a unique ID seems wrong to me You can tell me to use whatever works and that'll be a valid answer ;-)

• Best approach for a database of long strings

  - by gsingh2011

  I need to store questions and answers in a database. The questions will be one to two sentences, but the answers will be long, at least a paragraph, likely more. The only way I know about to do this right now is an SQL database. However, I don't feel like this is a good solution because as far as I've seen, these databases aren't used for data of this type or size. Is this the correct way to go or is there a better way to store this data? Is there a better way than storing raw strings?

• Automated build platform for .NET portfolio - best choice?

  - by jkohlhepp

  I am involved with maintaining a fairly large portfolio of .NET applications. Also in the portfolio are legacy applications built on top of other platforms - native C++, ECLIPS Forms, etc. I have a complex build framework on top of NAnt right now that manages the builds for all of these applications. The build framework uses NAnt to do a number of different things: Pull code out of Subversion, as well as create tags in Subversion Build the code, using MSBuild for .NET or other compilers for other platforms Peek inside AssemblyInfo files to increment version numbers Do deletes of certain files that shouldn't be included in builds / releases Releases code to deployment folders Zips code up for backup purposes Deploy Windows services; start and stop them Etc. Most of those things can be done with just NAnt by itself, but we did build a couple of extension tasks for NAnt to do some things that were specific to our environment. Also, most of those processes above are genericized and reused across a lot of our different application build scripts, so that we don't repeat logic. So it is not simple NAnt code, and not simple build scripts. There are dozens of NAnt files that come together to execute a build. Lately I've been dissatisfied with NAnt for a couple reasons: (1) it's syntax is just awful - programming languages on top of XML are really horrific to maintain, (2) the project seems to have died on the vine; there haven't been a ton of updates lately and it seems like no one is really at the helm. Trying to get it working with .NET 4 has cause some pain points due to this lack of activity. So, with all of that background out of the way, here's my question. Given some of the things that I want to accomplish based on that list above, and given that I am primarily in a .NET shop, but I also need to build non-.NET projects, is there an alternative to NAnt that I should consider switching to? Things on my radar include Powershell (with or without psake), MSBuild by itself, and rake. These all have pros and cons. For example, is MSBuild powerful enough? I remember using it years ago and it didn't seem to have as much power as NAnt. Do I really want to have my team learn Ruby just to do builds using rake? Is psake really mature enough of a project to pin my portfolio to? Is Powershell "too close to the metal" and I'll end up having to write my own build library akin to psake to use it on its own? Are there other tools that I should consider? If you were involved with maintaining a .NET portfolio of significant complexity, what build tool would you be looking at? What does your team currently use?

• What's the best approach to Facebook integration?

  - by Jay Stevens

  I have a new site/app going live next week (or somewhere close). I know there will be a relatively small (15,000?) very dedicated group of people on Facebook who will be very likely to be interested in the site, so I know I need Facebook integration of some kind. I won't be doing Facebook logins or pulling/posting to profiles yet, but I plan to... The question: Do I just do a Facebook "Page" for now? This is faster/easier to set up and seems a little less buggy.. and then migrate to a Facebook App later? or Do I create a "Facebook App" (with the api key/id/secret, etc.) now even if I'm doing nothing but using the "like" button. This means I don't have any migration later and I can use the javascript api to log "like" button clicks to Google Analytics, etc. Thoughts? Experiences? Is there a migration process to move your old Page users to your new "App"? What's the advantages / disadvantages of each.
