• How to deal with OpenGL and Fullscreen on OS X

  - by Armin Ronacher

  I do most of my development on OS X and for my current game project this is my target environment. However when I play games I play on Windows. As a windows gamer I am used to Alt+Tab switching from within the game to the last application that was open. On OS X I currently can't find either a game that supports that nor can I find a way to make it possible. My current project is based on SDL 1.3 and I can see that cmd+tab is a sequence that is sent directly to my application and not intercepted by the operating system. Now my first attempt was to hide the rendering window on cmd+tab which certainly works, but has the disadvantage that a hidden OpenGL window in SDL cannot be restored when the user tabs back to the application. First of all, there is no event fired for that or I can't find it, secondly the core problem is that when that application window is hidden, my game is still the active application, just that the window disappeared. That is incredible annoying. Any ideas how to approximate the windows / linux behavior for alt+tab?

• Google Analytics Visitors drop-off for certain region of site only

  - by crmpicco

  I have an issue with the tracking on my site where I have seen a dramatic drop off of visitors to the site from a certain region. I have four regions on my site at the moment, these are UK, EU, US and RoW (Rest of the World). The UK, EU and US regions are unaffected, only the RoW region suffers this drop-off. I have included a screen shot below from my GA account, which shows this effect. My GA code, which is included on every page on the site is below. I have changed the UA account number intentionally for this example. There have been no changes made to the GA account or the tracking code in a live environment for some considerable time, but for some reason I am seeing the drop-off for this region only. In the code below I am not tracking page views on certain pages as I have event tracking setup for these pages. <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-18721873-5']); _gaq.push(['_setCookiePath', '/row/']); if ( typeof(p_page) != 'undefined') { // do nothing if user is on above pages // N.B. there are a series of conditions in this if statement checking that we are not on a particular page } else { _gaq.push(['_trackPageview']); } </script>

• Should Developers Perform All Tasks or Should They Specialize?

  - by Bob Horn

  Disclaimer: The intent of this question isn't to discern what is better for the individual developer, but for the system as a whole. I've worked in environments where small teams managed certain areas. For example, there would be a small team for every one of these functions: UI Framework code Business/application logic Database I've also worked on teams where the developers were responsible for all of these areas and more (QA, analsyt, etc...). My current environment promotes agile development (specifically scrum) and everyone has their hands in every area mentioned above. While there are pros and cons to each approach, I'd be curious to know if there are more pros and cons than I list below, and also what the generally feeling is about which approach is better. Devs Do It All Pros 1. Developers may be more well-rounded 2. Developers know more of the system Cons 1. Everyone has their hands in all areas, increasing the probability of creating less-than-optimal results in that area 2. It can take longer to do something with which you are unfamiliar (jack of all trades, master of none) Devs Specialize Pros 1. Developers can create policies and procedures for their area of expertise and more easily enforce them 2. Developers have more of a chance to become deeply knowledgeable about their specific area and make it the best it can be 3. Other developers don't cross boundaries and degrade another area Cons 1. As one colleague put it: "Why would you want to pigeon-hole yourself like that?" (Meaning some developers won't get a chance to work in certain areas.) It's easy to say how wonderful agile is, and that we should do it all, but I'm somewhat of a fan of having areas of expertise. Without that expertise, I've seen code degrade, database schemas become difficult to manage, hack UI code, etc... Let's face it, some people make careers out of doing just UI work, or just database work. It's not that easy to just fill in and do as good of a job as an expert in that area.

• Code Clone Analysis on Rawr &ndash; Part 1

  - by Dylan Smith

  In this post we’ll take a look at the first result from the Code Clone Analysis, and do some refactoring to eliminate the duplication.  The first result indicated that it found an exact match repeated 14 times across the solution, with 18 lines of duplicated code in each of the 14 blocks.   Net Lines Of Code Deleted: 179     In this case the code in question was a bunch of classes representing the various Bosses.  Every Boss class has a constructor that initializes a whole bunch of properties of that boss, however, for most bosses a lot of these are simply set to 0’s.     Every Boss class inherits from the class MultiDiffBoss, so I simply moved all the initialization of the various properties to the base class constructor, and left it up to the Boss subclasses to only set those that are different than the default values. In this case there are actually 22 Boss subclasses, however, due to some inconsistencies in the code structure Code Clone only identified 14 of them as identical blocks.  Since I was in there refactoring the 14 identified already, it was pretty straightforward to identify the other 8 subclasses that had the same duplicated behavior and refactor those also.   Note: Code Clone Analysis is pretty slow right now.  It takes approx 1 min to build this solution, but it takes 9 mins to run Code Clone Analysis.  Personally, if the results are high quality I’m OK with it taking a long time to run since I don’t expect it’s something I would be running all that often.  However, it would be nice to be able to run it as part of a nightly build, but at this time I don’t believe it’s possible to run outside of Visual Studio due to a dependency on the meta-data available in the VS environment.

• Install tmux on Mac OS X

  - by unixben

  This is a short run down on how to get tmux running on your Mac OS X system. The same methodology applies when compiling this on Solaris. What is tmux? According to the developer's page, "tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached". Why not just use screen? For me, the primary reason I switched to tmux from screen is the much easier configuration syntax that tmux offers. If you've ever struggled with formatting screen's caption or hardstatus line, then you will appreciate the ease with which you can achieve the same results in tmux. Preparing your environment You will need a C compiler installed. I believe that OS X ships by default with GNU make, but if not, then you will need to obtain it or use Xcode. Download the sources While I'm putting all this together, I like to keep everything neatly tucked away in a build directory. mkdir ~/build cd ~/build curl -OL http://downloads.sourceforge.net/tmux/tmux-1.5.tar.gz curl -OL http://downloads.sourceforge.net/project/levent/libevent/libevent-2.0/libevent-2.0.16-stable.tar.gz Unpack the sources tar xzf tmux-1.5.tar.gz tar xzf libevent-2.0.16-stable.tar.gz Compiling libevent cd libevent-2.0.16-stable ./configure --prefix=/opt make sudo make install Compiling tmux cd ../tmux-1.5 LDFLAGS="-L/opt/lib" CPPFLAGS="-I/opt/include" LIBS="-lresolv" ./configure --prefix=/opt make sudo make install That's all there is to it!

• Can Mailchimp APIs be used to send templated transaction email triggered by actions on my website?

  - by HenryW

  I am currently playing around with Mailchimp's APIs, but the documentation to me is not very clear. Here is what I actually want: Have the templates I created on Mailchimp, be visible on my own server. Assign each template I made to a specific action (logged in,subscribed, created order, or new password). This is functionality that I already tested with Mandrill, but the template exists on mandrill's account. If option 1 is not possible, can I still make my own template in my own environment, and send that template out over Mailchimp or Mandrill? Should I use Mailchimps services for this or send the email directly from my own server? Curent used function: function tep_mandrill_mail($to_name, $to_email_address, $email_subject, $email_text, $from_email_name, $from_email_address) { if (SEND_EMAILS != 'true') return false; $uri = 'https://mandrillapp.com/api/1.0/messages/send-template.json'; $postString = '{ "key": "xxxxxxxxxxx", "template_name": "sometemplatename", "template_content": [ { "name": "header", "content": "*|HEADERSTUFF|*" }, { "name": "main", "content": "*|CONTENTSTUFF|*" }, { "name": "footer", "content": "*|FOOTERSTUFF|*" } ], "message": { "subject": "'.$email_subject.'", "from_email": "'.$from_email_adress.'", "from_name": "'.$from_email_name.'", "to": [ { "email": "'.$to_email_address.'", "name": "'.$to_name.'" } ], "important": false, "track_opens": true, "merge": true, "merge_vars": [ { "rcpt": "'.$to_email_address.'", "vars": [ { "name": "HEADERSTUFF", "content": "'.$email_subject.'" }, { "name": "CONTENTSTUFF", "content": "'.$email_text.'" }, { "name": "FOOTERSTUFF", "content": "paulvale-foot" } ] } ], "tags": [ "password_forgotten" ] }, "async": false, "ip_pool": "Main Pool" }'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $uri); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true ); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $postString); curl_exec($ch); }

• Tomcat + Spring + CI workflow

  - by ex3v

  We're starting our very first project with Spring and java web stack. This project will be mainly about rewriting quite large ERP/CRM from Zend Framework to Java. Important factor in my question is that I come from php territory, where things (in terms of quality) tend to look different than in java world. Fatcs: there will be 2-3 developers, at least one of developers uses Windows, rest uses Linux, there is one remote linux-based machine, which should handle test and production instances, after struggling with buggy legacy code, we want to introduce good programming and development practices (CI, tests, clean code and so on) client: internal, frequent business logic changes, scrum, daily deployments What I want to achieve is good workflow on as many development stages as possible (coding - commiting - testing - deploying). The problem is that I've never done this before, so I don't know what are best practices to do this. What I have so far is: developers code locally, there is vagrant instance on every development machine, managed by puppet. It contains the same linux, jenkins and tomcat versions as production machine, while coding, developer deploys to vagrant machine, after local merge to test branch, jenkins on vagrant handles tests, when everything is fine, developer pushes commits and merges jenkins on remote machine pulls commit from test branch, runs tests and so on, if everything looks green, jenkins deploys to test tomcat instance Deployment to production is manual (altough it can be done using helping scripts) when business logic is tested by other divisions and everything looks fine to client. Now, the real question: does above make any sense? Things that I'm not sure about: Remote machine: won't there be any problems with two (or even three, as jenkins might need one) instances of same app on tomcat? Using vagrant to develop on php environment is just vise. Isn't this overkill while using Tomcat? I mean, is there higher probability that tomcat will act the same on every machine? Is there sense of having local jenkins on vagrant?

• What's a way to implement a flexible buff/debuff system?

  - by gkimsey

  Overview: Lots of games which RPG-like statistics allow for character "buffs", ranging from simple "Deal 25% extra damage" to more complicated things like "Deal 15 damage back to attackers when hit." The specifics of each type of buff aren't really relevant. I'm looking for a (presumably object-oriented) way to handle arbitrary buffs. Details: In my particular case, I have multiple characters in a turn-based battle environment, so I envisioned buffs being tied to events like "OnTurnStart", "OnReceiveDamage", etc. Perhaps each buff is a subclass of a main Buff abstract class, where only the relevant events are overloaded. Then each character could have a vector of buffs currently applied. Does this solution make sense? I can certainly see dozens of event types being necessary, it feels like making a new subclass for each buff is overkill, and it doesn't seem to allow for any buff "interactions". That is, if I wanted to implement a cap on damage boosts so that even if you had 10 different buffs which all give 25% extra damage, you only do 100% extra instead of 250% extra. And there's more complicated situations that ideally I could control. I'm sure everyone can come up with examples of how more sophisticated buffs can potentially interact with each other in a way that as a game developer I may not want. As a relatively inexperienced C++ programmer (I generally have used C in embedded systems), I feel like my solution is simplistic and probably doesn't take full advantage of the object-oriented language. Thoughts? Has anyone here designed a fairly robust buff system before?

• How to control an actor movement in UDK

  - by Mikalichov

  This might be very basic, but I couldn't find something relevant to what I need (see below). I am working on a very basic thing: a 3D environment with some buildings, and actors walking inside it. It looks like following: I mainly want to manage to have one actor standing around, idling, and another walking around the area. Right now, this is done through matinee + skeletal mesh groups, and forcing a looped animation on the actors: But I realize this is super caveman-level. So I've build an AnimTree, linking the idling and directional animations to the corresponding nodes. But then, I'm stuck. I added the AnimTree in the actors properties, but nothing happens. I've tried MoveToActor, but no success - is there a thing to set to allow an actor to move? Also, I place the actors on the map manually (they are supposed to be unique), should I spawn them instead? Every tutorial I find explains how to use an AnimTree for the player character, which is not what I want. I need a way to move the actors. I tried to look for AI tutorials, but only found UT3 bots-modifications, which is not what I need either. Since I have so much trouble finding how to do this through Kismet, I'm starting to suspect this has to be done through scripting/coding, but I would like to be sure there is no way to do it through Kismet before going that route. Every bit of answer about how to tell an actor something along the lines of "go in that direction as much as you can, then when you hit a wall turn 45° and continue" would be awesome. I'll be happy to move/edit the question if there is any problem with it

• How safe is it to rely on thirdparty Python libs in a production product?

  - by skyler

  I'm new to Python and come from the write-everything-yourself world of PHP (at least this is how I always approached it). I'm using Flask, WTForms, Jinja2, and I've just discovered Flask-Login which I want to use. My question is about the reliability of using thirdparty libraries for core functionality in a project that is planned to be around for several years. I've installed these libraries (via pip) into a virtualenv environment. What happens if these libraries stop being distributed? Should I back up these libraries (are they eggs)? Can I store these libraries in my project itself, instead of relying on pip to install them in a virtualenv? And should I store these separately? I'm worried that I'll rely on a library for core functionality, and then one day I'll download an incompatible version through pip, or the author or maintainer will stop distributing it and it'll no longer be available. How can I protect against this, and ensure that any thirdparty libraries that I use in my projects will always be available as they are now?

• Discovery methods

  - by Owen Allen

  In Ops Center, asset discovery is a process in which the software determines what assets exist in your environment. You can't monitor an asset, or do anything to it through Ops Center, until it's discovered. I've seen a couple of questions about how to discover various types of asset, so I thought I'd explain the discovery methods and what they each do. Find Assets - This discovery method searches for service tags on all known networks. Service tags are small files on some hardware and operating systems that provide basic identification info. Once a service tag has been found, you provide credentials to manage the asset. This method can discover assets quickly, but only if the target assets have service tags. Add Assets with discovery profile - This method lets you specify targets by providing IP addresses, IP ranges, or hostnames, as well as the credentials needed to connect to and manage these assets. You can create discovery profiles for any type of asset. Declare asset - This method lets you specify the details of a server, with or without a configured service processor. You can then use Ops Center to install a new operating system or configure the SP. This method works well for new hardware. These methods are all discussed in more detail in the Asset Management chapter of the Feature Reference guide.

• Existing laravel 4 project gives 404 in browser

  - by Richard A

  I'm trying to set up a development environment on a virtual machine running Ubuntu 14.04 LTS using Nginx and HHVM. To do this, I followed the tutorial here. This goes well with a new installation of Laravel. But when I import an existing Laravel 4 project and try to open that on my actual machine (which will serve as the client running Windows 7), I'm getting a 404 File Not Found error on the screen while connecting to http://sav.savrichard.dev. I did add this to the hosts file with the correct IP Address. The virtual machine is receiving the request and responds with a 404 error. How do I solve this error? I'm pretty new to Ubuntu so I'm not exactly sure what's wrong. The project is located at /var/www/sav.savrichard.net The server configuration is as follow: server { listen 80 default_server; root /var/www/sav.savrichard.net/public; index index.html index.htm index.php; server_name sav.savrichard.dev; access_log /var/log/nginx/localhost.sav.savrichard.dev-access.log; error_log /var/log/nginx/localhost.sav.savrichard.dev-error.log error; charset utf-8; location / { try_files \$uri \$uri/ /index.php?\$query_string; } location = /favicon.ico { log_not_found off; access_log off; } location = /robots.txt { log_not_found off; access_log off; } error_page 404 /index.php; include hhvm.conf; # Deny .htaccess file access location ~ /\.ht { deny all; } } And the hhvm.conf file is: location ~ \.(hh|php)$ { fastcgi_keep_conn on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• How to implement "bullet time" in a multiplayer game?

  - by Tom

  I have never seen such a feature before, but it should provide an interesting gameplay opportunity. So yes, in a multiplayer/real-time environment (imagine FPS), how could I implement a slow motion/bullet time effect? Something like an illusion for the player that's currently slo-mo'ed. So everybody sees him "real-time", but he sees everything slowed down. Update A sidenote: keep in mind that a FPS game has to be balanced in order for it to be fun. So yes, this bullet time feature has to be solid, giving a small advantage to the "player", while not taking away from other players. Plus, there is a possibility that two players could activate their bullet time at the same time. Furthermore: I'm going to implement this in the future no matter what it takes. And, the idea is to build a whole new game engine for all this. If that gives new options, I'm more then interested in hearing the ideas. Meanwhile, here with my team we're thinking about this too, when our theory will be crafted, I'm going to share it here. Is this even possible? So, the question on "is this even possible" has been answered, now it's time to find the best solution. I'm keeping the "answer" until something exceptionally good comes up, like a prototype theory with something close to working pseudo code.

• PHP Image gallery that integrates well into custom CMS

  - by Thorarin

  I've been trying to find an image gallery that plays nice with our custom CMS. I've evaluated a number of them, but none of them seems to have the feature list that I would like: Run on LAMP environment Free software or low license costs (the website belongs to a non-profit organisation) Multi-user support Multiple albums. We're posting concert pictures, and would like an album per event. Pluggable authentication system. I want to reuse the accounts we have for our CMS. Permissions can be done inside the gallery itself, but I want to have a single sign on solution in a maintainable manner, by writing my own plugin/add-on for the software. Upload support (multiple images at the same time) And preferrably also: Can be integrated into a PHP page layout without IFRAMEs Automatic resizing of uploaded images to a maximum size Ability for visitors to place comments This combination is proving hard to find, especially the authentication requirement. I don't want to mess around all over the place in the source code to make it use the existing authentication. A plugin would be ideal, but alternatively a well thought out software design that allows for maintainable surgical changes would be acceptable. Any suggestions on which software I should take a closer look into?

• How to react to an office harassment based on my profession ? [closed]

  - by bob from jersey

  A lot of my co-workers (not developers, people from the other departments) who are framing me in the classical "nerd" stereotype, and with that acting disturbing towards me. Of course they are not aggressive or anything, since we are in a work environment having rules on it's own, plus we are all grownups now, but they are on a "quite war" against me (not particularly against me, they are against all developers, but I am the only one who dares to speak about it). I hear names, "nerd", "geek", "cyborg", "outsider" and so on, it's really inappropriate. Of course, nothing is said in our faces, but, you know, "you hear things over". Also this general feeling of "them not liking us at all" can be sensed in the air all the time. And while it is not a problem for a few weeks, a larger duration of constant office harassment (going for months now), can be really annoying and can cause a serious drop in the development performance, which will (inevitably) lead to problems with the management (maybe getting me fired). I want to know, should I continue with my current defensive strategy (passively ignoring their inappropriate labels) or should I switch into a more aggressive maneuvers, like giving them logical reasons why their antisocial behavior should be banned?

• What is a Coding Dojo?

  - by huwyss

  Recently i found out that there is a thing called "coding dojo". The point behind it is that software developers want to have a space to learn new stuff like processes, methods, coding details, languages, and whatnot in an environment without stress. Just for fun. No competition. No results required. No deadlines.Some days ago I joined the Zurich coding dojo. We were three programmers with different backgrounds.We gave ourselves the task to develop a method that takes an input value and returns its prime factors. We did pair programming and every few minutes we switched positions. We used test driven development. The chosen programming language was Ruby.I haven't really done TDD before. It was pretty interesting to see the algorithm develop following the testcases.We started with the first test input=1 then developed the most simple productive program that passed this very first test. Then we added the next test input=2 and implemented the productive code. We kept adding tests and made sure all tests are passed until we had the general solution.When we improved the performance of our code we saw the value of the tests we wrote before. Of course our first performance improvement broke several tests.It was a very interesting experience to see how other developers think and how they work. I will participate at the dojo again and can warmly recommend it to anyone. There are  coding dojos all over the world.Have fun!

• TXPAUSE : polite waiting for hardware transactional memory

  - by Dave

  Classic locks are an appropriate tool to prevent potentially conflicting operations A and B, invoked by different threads, from running at the same time. In a sense the locks cause either A to run before B or vice-versa. Similarly, we can replace the locks with hardware transactional memory, or use transactional lock elision to leverage potential disjoint access parallelism between A and B. But often we want A to wait until B has run. In a Pthreads environment we'd usually use locks in conjunction with condition variables to implement our "wait until" constraint. MONITOR-MWAIT is another way to wait for a memory location to change, but it only allows us to track one cache line and it's only available on x86. There's no similar "wait until" construct for hardware transactions. At the instruction-set level a simple way to express "wait until" in transactions would be to add a new TXPAUSE instruction that could be used within an active hardware transaction. TXPAUSE would politely stall the invoking thread, possibly surrendering or yielding compute resources, while at the same time continuing to track the transaction's address-set. Once a transaction has executed TXPAUSE it can only abort. Ideally that'd happen when some other thread modifies a variable that's in the transaction's read-set or write-set. And since we're aborting all writes would be discarded. In a sense this gives us multi-location MWAIT but with much more flexibility. We could also augment the TXPAUSE with a cycle-count bound to cap the time spent stalled. I should note that we can already enter a tight spin loop in a transaction to wait for updates to address-set to cause an abort. Assuming that the implementation monitors the address-set via cache-coherence probes, by waiting in this fashion we actually communicate via the probes, and not via memory values. That is the updating thread signals the waiter via probes instead of by traditional memory values. But TXPAUSE gives us a polite way to spin.

• IDC Recommends Oracle Solaris 11

  - by user12611852

  IDC published a research report this week on Oracle Solaris 11 and described it as "Delivering unique value."  The report emphasizes the ability of Oracle Solaris to scale up and provide a mission critical platform for a wide variety of computing. Solaris built-in server and network virtualization helps to lower costs and enable consolidation while reducing administration costs and risks. Learn more about Oracle Solaris and the recently announced 11.1 update. In their conclusion, IDC reports: Today, Oracle is a multi-OS vendor that is adjusting to the opportunities presented by a significantly expanded product portfolio. The company has a long history of supporting Unix operating systems with its broad product portfolio, but the main difference is that now Oracle has direct control over the destiny of the Solaris operating system. The company has made a strong commitment to Solaris on both SPARC and x86 systems, as well as to Linux on x86 systems, and expects to continue to enhance Oracle Solaris 11 with update releases once a year as well as Solaris 12, which is already on the road map. Oracle is working to help its customers understand its strong commitment to Oracle Solaris and the product's role as a single operating system that runs on both SPARC and x86 processors. While Oracle Solaris and Oracle Linux are critical assets, the company's crown jewel is the deep collection of software that runs on top of both Oracle Solaris and Oracle Linux, software that creates a robust application environment. The continuing integration and optimization of the software and hardware stack is a differentiator for Oracle and for customers that run an Oracle Solaris stack.

• The SQL Server Setup Portal

  - by BuckWoody

  One of the tasks that takes a long time for the data professional is setting up SQL Server. No, it isn’t that difficult to slide a DVD in a drive and click “Setup” but the overall process of planning the hardware and software environment, making decisions for high-availability, security and dozens of other choices can make the process more difficult. And then, of course, there are the inevitable issues that arise. Microsoft supports literally hundreds and even thousands of combinations of hardware and software drivers from vendors you’ve never even heard of. Making all of that work together is a small miracle, so things are bound to arise that you need to deal with. So, to help you out, we’ve designed a new “SQL Server Setup Portal”. It’s a one-stop-shop for everything you need to know about planning and setting up SQL Server. As time goes on you’ll see even more content added. There are already whitepapers, videos, and multiple places to search on everything from topic names to error codes. So go check it out – and if you have to do a lot of SQL Server Setups – and especially if you don’t – bookmark it as a favorite!
