• AABB Sweeping, algorithm to solve "stacking box" problem

  - by Ivo Wetzel

  I'm currently working on a simple AABB collision system and after some fiddling the sweeping of a single box vs. another and the calculation of the response velocity needed to push them apart works flawlessly. Now on to the new problem, imagine I'm having a stack of boxes which are falling towards a ground box which isn't moving: Each of these boxes has a vertical velocity for the "gravity" value, let's say this velocity is 5. Now, the result is that they all fall into each other: The reason is obvious, since all the boxes have a downward velocity of 5, this results in no collisions when calculating the relative velocity between the boxes during sweeping. Note: The red ground box here is static (always 0 velocity, can utilize spatial partitioning ), and all dynamic static collisions are resolved first, thus the fact that the boxes stop correctly at this ground box. So, this seems to be simply an issue with the order the boxes are sweept against each other. I imagine that sorting the boxes based on their x and y velocities and then sweeping these groups correctly against each other may resolve this issues. So, I'm looking for algorithms / examples on how to implement such a system. The code can be found here: https://github.com/BonsaiDen/aabb The two files which are of interest are [box/Dynamic.lua][3] and [box/Manager.lua][4]. The project is using Love2D in case you want to run it.

• Instructor Insight: Using the Container Database in Oracle Database 12 c

  - by Breanne Cooley

  The first time I examined the Oracle Database 12c architecture, I wasn’t quite sure what I thought about the Container Database (CDB). In the current release of the Oracle RDBMS, the administrator now has a choice of whether or not to employ a CDB. Bundling Databases Inside One Container In today’s IT industry, consolidation is a common challenge. With potentially hundreds of databases to manage and maintain, an administrator will require a great deal of time and resources to upgrade and patch software. Why not consider deploying a container database to streamline this activity? By “bundling” several databases together inside one container, in the form of a pluggable database, we can save on overhead process resources and CPU time. Furthermore, we can reduce the human effort required for periodically patching and maintaining the software. Minimizing Storage Most IT professionals understand the concept of storage, as in solid state or non-rotating. Let’s take one-to-many databases and “plug” them into ONE designated container database. We can minimize many redundant pieces that would otherwise require separate storage and architecture, as was the case in previous releases of the Oracle RDBMS. The data dictionary can be housed and shared in one CDB, with individual metadata content for each pluggable database. We also won’t need as many background processes either, thus reducing the overhead cost of the CPU resource. Improve Security Levels within Each Pluggable Database  We can now segregate the CDB-administrator role from that of the pluggable-database administrator as well, achieving improved security levels within each pluggable database and within the CDB. And if the administrator chooses to use the non-CDB architecture, everything is backwards compatible, too.  The bottom line: it's a good idea to at least consider using a CDB. -Christopher Andrews, Senior Principal Instructor, Oracle University

• How to re-add a missing font

  - by WEFX

  I recently upgraded from Office 2007 to 2010, and that went fairly smoothly. However, afterwards, my Calibri font was gone, so my Word and Outlook started using the next available font in the list... Comic Sans! I browsed to Control Panel Fonts, and saw that there was no longer a Calibri listing. I know that one way to recover a missing font is to just copy the missing font files from another computer. In my case, the four files I needed were: calibri.ttf, //regular calibrib.ttf, //bold calibrii.ttf, //italics calibriz.ttf, //bold and italics However, once I attempted to copy-and-paste these files to my computer, I realized these files were already on my problem computer; they never really got erased. I don't know why they aren't working in Office, and they aren't listed in Control Panel Fonts.

• How to prevent hard drive from spinning down Windows 7?

  - by JL.

  I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?

• Remote Desktop Mobile mangles barcodes coming from scanner

  - by sfonck

  Hi, We have an application here using handhelds to scan barcodes. These handhelds are actually making a remote desktop session towards a server where the application runs. Works fine. Now we have bought some new Motorola MC55's running 'Windows Mobile 6.1 Classic', and when using the application over remote desktop: it mangles the characters of the barcodes.... I already tried following things: When scanning a barcode on the MC55 itself it is displayed correctly When scanning a barcode via the remote desktop into a notepad session it is incorrect. Played with all options of the 'Remote Desktop Mobile' - no result Disabled 'autocorrect' and 'suggest words when entering text' on the input settings - no result The strange things is: a barcode which consists of only numbers gets scanned correctly the mangled characters comes through in lower case For some codes \t is mangled in between (should normally be entered after the barcode) e.g.: 'PERIN4' becomes 'ERINp4' 'MGZB' becomes 'GZB m' 'BAK664' becomes 'AK664 b' 'MAGBFA01' becomes 'AGBFmA01' '5021879949500' gets scanned correctly Anybody an idea how I could solve this problem?

• Unused Indexes Gotcha

  - by DavidWimbush

  I'm currently looking into dropping unused indexes to reduce unnecessary overhead and I came across a very good point in the excellent SQL Server MVP Deep Dives book that I haven't seen highlighted anywhere else. I was thinking it was simply a case of dropping indexes that didn't show as being used in DMV sys.dm_db_index_usage_stats (assuming a solid representative workload had been run since the last service start). But Rob Farley points out that the DMV only shows indexes whose pages have been read or updated. An index that isn't listed in the DMV might still be useful by providing metadata to the Query Optimizer and thus streamlining query plans. For example, if you have a query like this: select  au.author_name         , count(*) as books from    books b         inner join authors au on au.author_id = b.author_id group by au.author_name If you have a unique index on authors.author_name the Query Optimizer will realise that each author_id will have a different author_name so it can produce a plan that just counts the books by author_id and then adds the author name to each row in that small table. If you delete that index the query will have to join all the books with their authors and then apply the GROUP BY - a much more expensive query. So be cautious about dropping apparently unused unique indexes.

• NetBeans Sources as a Platform

  - by Geertjan

  By default, when you create a new NetBeans module, the 'development IDE' is the platform to which you'll be deploying your module. It's a good idea to create your own platform and check that into your own repo, so that everyone working on your project will be able to work with a standardized platform, rather than whatever happens to be beneath the development IDE your using. Something else you can do is use the NetBeans sources as your platform, once you've checked them out. That's something I did the other day when trying to see whether adding 'setActivatedNodes' to NbSheet was sufficient for getting UndoRedo enabled in the Properties Window. So that's a good use case, i.e., you'd like to change the NetBeans Platform somehow, or you're fixing a bug, in other words, in some way you need to change the NetBeans Platform sources and then would like to try out the result of your changes as a client of your changes. In that scenario, here's how to set up and use a NetBeans Platform from the NetBeans sources. Run 'ant build platform' on the root of the NetBeans sources. You'll end up with nbbuild/netbeans containing a subfolder 'platform' and a subfolder 'harness'. There's your NetBeans Platform. Go to Tools | NetBeans Platform and browse to nbbuild/netbeans', registering it as your NetBeans Platform. Create a new NetBeans module, using the new NetBeans Platform as the platform. Now the cool thing is you can open any of the NetBeans modules from the NetBeans Platform modules in the NetBeans sources. When you change the source code of one of these modules and then build that module, the changed JAR will automatically be added to the right place in the nbbuild/netbeans folder. And when you do a 'clean' on a NetBeans Platform module, the related JAR will be removed from nbbuild/netbeans. In other words, in this way, by changing the NetBeans sources, you're directly changing the platform that your custom module will be running on when you deploy it. That's pretty cool and gives you a more connected relationship to your platform, since you're able to change it in the same way as the custom modules you create.

• My Windows 8 computer does not come out of Standby

  - by Jikag

  My computer will not come out out of standby. It has had this issue ever since I bought it ~4 years ago. When I purchased it, It came with Vista, I have since upgraded it to 7 and now 8 Pro, each time hoping that it would fix the problem, each time finding that it did not. My computer is an HP Pavilion Model #: m9500y. The computer goes into standby, but does not come out of it properly. If Hybrid sleep in on, it does not respond at all. If Hybrid sleep is off, It comes out and I can see the desktop for a bit, but then the screen goes black again and I have to reboot. I have tried Running a sfc, and a chkdsk in case it's a corrupted file, but it hasn't helped. This isn't too serious an issue because I can just shutdown my computer and turn it on the old fashioned way, but it is annoying and I would appreciate some advice going forward as I'm currently stumped.

• apache not displaying php pages, offering them for download instead.

  - by Peter NUnn

  Hi folks, we are trying to setup apache (apache 2 in this case, although apache does the same thing) and html pages display just fine, however, any php pages linked into buttons on the front page are offered for download rather than being displayed. Any ideas what we have missed? Its proving difficult to search on this in google as the terms are so heavily used elsewhere. I know this is a bit general, but we have tried adding types to the to the apache.conf (or httpd.conf for apache1) are having no joy at all. Thanks. Peter.

• Bug with Set / Get Accessor in .Net 3.5

  - by MarkPearl

  I spent a few hours scratching my head on this one... So I thought I would blog about it in case someone else had the same headache. Assume you have a class, and you are wanting to use the INotifyPropertyChanged interface so that when you bind to an instance of the class, you get the magic sauce of binding to do you updates to the UI. Well, I had a special instance where I wanted one of the properties of the class to add some additional formatting to itself whenever someone changed its value (see the code below).   class Test: INotifyPropertyChanged {     private string_inputValue;     public stringInputValue     {         get        {             return_inputValue;         }         set        {             if(value!= _inputValue)             {                 _inputValue = value+ "Extra Stuff";                 NotifyPropertyChanged("InputValue");                     }         }     }     public eventPropertyChangedEventHandler PropertyChanged;     public voidNotifyPropertyChanged(stringinfo)     {         if(PropertyChanged != null)         {             PropertyChanged(this, newPropertyChangedEventArgs(info));         }     } }   Everything looked fine, but when I ran it in my WPF project, the textbox I was binding to would not update? I couldn’t understand it! I thought the code made sense, so why wasn’t it working? Eventually StackOverflow came to the rescue, where I was told that it was a bug in the .Net 3.5 Runtime and that a fix was scheduled in .Net 4 For those who have the same problem, here is the workaround… You need to put the NotifyPropertyChanged method on the application thread! public string InputValue { get { return _inputValue; } set { if (value != _inputValue) { _inputValue = value + "Extra Stuff"; // // React to the type of measurement // Application.Current.Dispatcher.BeginInvoke((Action)delegate { NotifyPropertyChanged("InputValue"); }); } } }

• PHP 5.4 not available for windows + Apache?

  - by user410932

  I'd like to install the new PHP 5.4 on my Windows machine. I'm running Apache 2.2 on it. Reading the info on http://windows.php.net/download/, it says "If you are using PHP with Apache 1 or Apache2 from apache.org you need to use the VC6 versions of PHP". I guess I'm in that case, I just donloaded Apache from apache.org. However, there are no VC6 versions available of PHP 5.4, not even of PHP 5.3. How can I install PHP 5.4 on my Windows machine then ?

• Master-Details with RadGridView for Silverlight 4, WCF RIA Services RC2 and Entity Framework 4.0

  I have prepared a sample project with the Silverlight 4 version of RadGridView released yesterday. The sample project was created with Visual Studio 2010, WCF RIA Services RC 2 for Visual Studio 2010, and ADO.NET Entity Framework (.NET 4). I have decided to use the SalesOrderHeader and SalesOrderDetails tables from the Adventure Works Database, because they provide the perfect one-to-many relationship: I will not go over the steps for creating the ADO.NET Entity Data Model and the Domain Service Class. In case you are not familiar with them, you should start with Brad Abrams series of blog posts and read this blog after that. To enable the master-details relationship we need to modify two things. First of all we need to include the automatic retrieval of the child entities in the domain service class. We do this by using the Include method: 1: public IQueryable<SalesOrderHeader> GetSalesOrderHeaders()...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• TDD/Tests too much an overhead/maintenance burden?

  - by MeshMan

  So you've heard it many times from those who do not truly understand the values of testing. Just to start things out, I'm a follower of Agile and Testing... I recently had a discussion about performing TDD on a product re-write where the current team does not practice unit testing on any level, and probably have never heard of the dependency injection technique or test patterns/design etc (we won't even get on to clean code). Now, I am fully responsible for the rewrite of this product and I'm told that attempting it in the fashion of TDD, will merely make it a maintenance nightmare and impossible for the team maintain. Furthermore, as it's a front-end application (not web-based), adding tests is pointless, as the business drive changes (by changes they mean improvements of course), the tests will become out of date, other developers who come on to the project in the future will not maintain them and become more of a burden for them to fix etc. I can understand that TDD in a team that does not currently hold any testing experience doesn't sound good, but my argument in this case is that I can teach my practice to those around me, but further more, I know that TDD makes BETTER software. Even if I was to produce the software using TDD, and throw all the tests away on handing it over to a maintenance team, it surely would be a better approach than not using TDD at all from the start? I've been shot down as I've mentioned doing TDD on most projects for a team that have never heard of it. The thought of "interfaces" and strange looking DI constructors scares them off... Can anyone please help me in what is normally a very short conversation of trying to sell TDD and my approach to people? I usually have a very short window of argument before falling at the knees to the company/team.

• Syslog/kernlog filling up with "did not claim interface N before use"

  - by Wayne Werner

  As I discovered when asking this question, it appears that demond_nscan is trying to use a device without claiming it. And it does it.... hundreds of time per second apparently. This makes kern.log and syslog huge (100GB ). In this particular case the problem is directly a result of some Lexmark drivers that were installed (found at /usr/local/lexmark/unix_scan_drivers/bin/demond_nscan). Here are a few things I know: The drivers are for an all-in-one printer/scanner device. There was a previous lexmark printer-only that was installed with CUPS This driver was the one for CUPS systems, and I think that it automatically added it to the list of printers in CUPS. The issue started spamming kern/syslog only after these drivers were installed, using the lexmark installers While googling around I found this thread that's not completely related, but it does mention that it might be happening when two drivers try to control the same device at the same time. How can I resolve this issue so that either I only have one driver, or get the driver to claim the device before usage?

• How would I `wget` files and then save them by date downloaded rather than filename?

  - by searchfgold6789

  My goal: To download 131 JPEGs and save them in a file name format that is relative to the date/time format rather than their file name. I have already tried things that involve changing the files' names after they have already been downloaded. However, these methods do not work because it seems like exif data is not being kept. For example: jhead -n%Y%m%d-%H%M%S *.jpg just returns a bunch of errors saying: Possible new names for for '{filename}.jpg' already exist File '{filename}.jpg' contains no exif date stamp. Using file date Usually, as in this case, I wind up with less files than I started out with. So is there some command I can pass to wget instead? I have already tried the --timestamp option with no success. (The man page is not to clear about what that does.)

• Differences in memory consumption between two identical D7 sites?

  - by aendrew

  I'm running Drupal on a news site that has a lot of different View blocks on the front page (~5 total, all cached). In trying to reduce the memory footprint of the site, I've checked out source from SVN to a local development install to try and convert some of those blocks into more optimized code. Here's the weird thing. Devel module lists memory consumption at 50mb on the Production site (Running Nginx, PHP 5.2.17, XCache and Zend Optimizer.) but only 14mb on my development site (Running Apache2, PHP 5.2.13 and XCache). These are nearly-identical versions of the same site — frankly, the Production site should use even less memory as I've disabled some of the modules running on the Dev site. Any idea why this might be the case?

• How to structure an application that combines WCF and WPF

  - by CiaranG

  I'm in the process of learning how to use WCF (Windows Communication Foundation) to allow a client/server desktop application to communicate. The application's UI will be implemented using WPF, and we will probably use SQL Server for our database. What I'm struggling with, is understanding how to structure such an application. From what I've read, there are three components of a WCF application (which in the examples I've seen have existed as separate projects): A WCF service A WCF service host A WCF service client My question then, is - should these projects solely implement the functionality of sending/receiving data from the client/server? Would it make better sense this way? Would it make sense to create a separate WPF (Windows Presentation Foundation) project to implement the UI for the application? And so, when I need to send/receive data from the client/server, I could simply invoke the operations provided in the WCF projects that I have created? For anyone who has built similar applications previously, perhaps you could explain what worked best for you in terms of structuring your application? For example, if I create a user registration page. When the user clicks the 'Register' button, the client application will need to send the data to the server. In this case, could I just invoke the methods provided in the WCF projects to send the data? Also, what data structures worked best for you when sending/receiving data? My initial thought is sending/receiving XML containing the data. Is this an option that is easy to implement? I realise that answers to this question may well be a matter of opinion - unless there are specific best practices that I'm not aware of. Thank you

• Is there a webproxy via email?

  - by mafutrct

  This is probably a bit weird, and I don't think it exists yet. I'm basically asking for a program that, upon receiving a request via email, downloads a html page and sends it via email, possibly changing the links inside the page into outgoing emails to this program asking for another page. This is certainly one of the most crude ways of accessing the web, and obviously fails at anything beyond the most basic stuff. But it may still be useful to those that can send email, but can't access the web due to company policy or whatever reason. In the (likely) case this does not exist, I'd be interested to write such a proxy.

• MvcExtensions - ActionFilter

  - by kazimanzurrashid

  One of the thing that people often complains is dependency injection in Action Filters. Since the standard way of applying action filters is to either decorate the Controller or the Action methods, there is no way you can inject dependencies in the action filter constructors. There are quite a few posts on this subject, which shows the property injection with a custom action invoker, but all of them suffers from the same small bug (you will find the BuildUp is called more than once if the filter implements multiple interface e.g. both IActionFilter and IResultFilter). The MvcExtensions supports both property injection as well as fluent filter configuration api. There are a number of benefits of this fluent filter configuration api over the regular attribute based filter decoration. You can pass your dependencies in the constructor rather than property. Lets say, you want to create an action filter which will update the User Last Activity Date, you can create a filter like the following: public class UpdateUserLastActivityAttribute : FilterAttribute, IResultFilter { public UpdateUserLastActivityAttribute(IUserService userService) { Check.Argument.IsNotNull(userService, "userService"); UserService = userService; } public IUserService UserService { get; private set; } public void OnResultExecuting(ResultExecutingContext filterContext) { // Do nothing, just sleep. } public void OnResultExecuted(ResultExecutedContext filterContext) { Check.Argument.IsNotNull(filterContext, "filterContext"); string userName = filterContext.HttpContext.User.Identity.IsAuthenticated ? filterContext.HttpContext.User.Identity.Name : null; if (!string.IsNullOrEmpty(userName)) { UserService.UpdateLastActivity(userName); } } } As you can see, it is nothing different than a regular filter except that we are passing the dependency in the constructor. Next, we have to configure this filter for which Controller/Action methods will execute: public class ConfigureFilters : ConfigureFiltersBase { protected override void Configure(IFilterRegistry registry) { registry.Register<HomeController, UpdateUserLastActivityAttribute>(); } } You can register more than one filter for the same Controller/Action Methods: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(); You can register the filters for a specific Action method instead of the whole controller: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(c => c.Index()); You can even set various properties of the filter: registry.Register<ControlPanelController, CustomAuthorizeAttribute>( attribute => { attribute.AllowedRole = Role.Administrator; }); The Fluent Filter registration also reduces the number of base controllers in your application. It is very common that we create a base controller and decorate it with action filters and then we create concrete controller(s) so that the base controllers action filters are also executed in the concrete controller. You can do the  same with a single line statement with the fluent filter registration: Registering the Filters for All Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type))); Registering Filters for selected Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type) && (type.Name.StartsWith("Home") || type.Name.StartsWith("Post")))); You can also use the built-in filters in the fluent registration, for example: registry.Register<HomeController, OutputCacheAttribute>(attribute => { attribute.Duration = 60; }); With the fluent filter configuration you can even apply filters to controllers that source code is not available to you (may be the controller is a part of a third part component). That’s it for today, in the next post we will discuss about the Model binding support in MvcExtensions. So stay tuned.

• How to set default xrandr settings?

  - by echo-flow

  I'm trying to enable dual monitors in Ubuntu. This is working fine, but every time I do it, desktop effects is disabled. I think I've found the reason why, though: https://wiki.ubuntu.com/X/Config/Multihead/ As with the GNOME XRandR configuration method, setting Virtual to too large a value may result in a loss of hardware acceleration, and thus an inability to use Compiz and its desktop effects. When I use the GNOME monitor applet, or the Monitors configuration in the System menu, the default xrandr settings puts the second monitor to the right of the first, and, as I found with this bug, for most monitors this creates a virtual desktop larger than the maximum 2048 horizontal resolution needed for hardware acceleration on my netbook hardware. So, it seems like if I can modify xrandr's default settings so that it places the new desktop above or below (north or south of) the main LVDS display, then hardware acceleration, and therefore compiz will continue to work. Can anyone tell me, what is the easiest way to achieve this? UPDATE: I have confirmed that multihead support with desktop effects and hardware acceleration works when I move the external monitor display north of the main LVDS display. Right now this involves the following process: plugging in the external monitor, starting the Monitors configuration menu, desktop effects are disabled automatically (and all of the windows on my workspaces are moved to the first workspace), repositioning the external display so that it is north of LVDS display and clicking apply, and then navigating to the Appearance menu and telling it to reenable desktop effects. Is there a simpler way do this? UPDATE 2: OK, so I thought that perhaps the GNOME Monitors configuration screen was trying to be clever, and might be disbling desktop effects. So, I just tried using the xrandr command-line client instead, as follows: xrandr --output VGA1 --above LVDS1 When I do that, desktop effects are still disabled, and I need to manually reenable them. This, despite the fact that hardware acceleration works, and there is never a point where hardware acceleration stops working because the horizontal dimension of the virtual display is too large. So what program is trying to be clever, and is turning off desktop effects when it doesn't need to? And how do I make it stop? If there were a way to re-enable desktop effects from the command line, which I could then put into a script along with the proper xrandr invocation, I would accept that as a workaround. UPDATE 3: OK, here's my script to enable a second monitor with desktop effects.

• route port 3000 to apache2 alias

  - by user223470

  I have a meteor application running on port 3000. I can successfully connect to the program with www.myurl.com:3000, but would rather connect to it via www.myurl.com/myappname. I started with the instructions on this web site: http://www.andrehonsberg.com/article/deploy-meteorjs-vhosts-ubuntu1204-mongodb-apache-proxy and I have the following Apache configuration file: <VirtualHost *:80> ServerName myurl.com ProxyRequests off <Proxy *> Order deny,allow Allow from all </Proxy> <Location /> ProxyPass http://localhost:3000/ ProxyPassReverse http://localhost:3000/ </Location> </VirtualHost> I do not know how to continue from here to get the program on www.mysite.com/myapp. In other situations, I would use an Alias within the Apache configuration file, but that doesn't seem like the right direction to go in this case. How do I configure Apache to send port 3000 to www.myurl.com/myapp?

• How does fail2ban 0.9 database storage actually works?

  - by Arantir

  Fail2ban 0.9 introduce database storage to save bans on restart. But I can't find out the actual mechanism of it work. There is dbpurgeage parameter which controls lifetime of old bans, defaults to 24 hours. As I see from code research, fail2ban saves a ban to the db with timeofban equals to the moment of ban being saved. Then every dbpurgeage period it removes all bans with timeofban < MyTime.time() - self._purgeAge, in other words removes all bans have been stored more than 24 hours ago. But what if an IP was banned for the month? Does all this mean that with dbpurgeage = 86400 after restart in 24 hours I will lost all bans longer than 24 hours? I just want that all my permanent bans will be preserved in any case.

• How to disable Apache http compression (mod_deflate) when SSL stream is compressed

  - by Mohammad Ali

  I found that Goggle Chrome supports ssl compression and Firefox should support it soon. I'm trying to configure Apache to to disable http compression if the ssl compression is used to prevent CPU overhead with the configuration option: SetEnvIf SSL_COMPRESS_METHOD DEFLATE no-gzip While the custom log (using %{SSL_COMPRESS_METHOD}x) shows that the ssl layer compression method is DEFLATE, the above option did not work and the http response content is still being compressed by Apache. I had to use the option: BrowserMatchNoCase ".Chrome." no-gzip' I prefer if there are more general method in case other browsers supports ssl compression or some has a version of chrome that does not have ssl compression.
