  • Software centre and Evolution think I am offline using WICD to make wireless connection

    - by Alex
    I upgraded to 11.10 yesterday. I use WICD to make the wireless connection because I have never managed to get network manager to make a wireless connection on any computer I have installed it on. But since 11.10 both Evolution and software centre are convinced I am offline even though I have a functional connection (I am using wifi now and both are reporting me offline, which I clearly am not). I am using an MSI WIND clone Advent 4211 B netbook. Network manager has never worked on this computer for wifi. WICD can make connection about 30% time (often returns BAD PASSWORD, first few attempts). XP of course works fine to make wifi connection. I have a I am happy to supply more information I just do not know what information might help. I have reported a bug against evolution

  • How to dump a MediaWiki for offline use?

    - by Sandra Schlichting
    I would like to be able to make an offline version of a MediaWiki site on a weekly basis. The DumpHTML extension actually does what I want, as it dumps all articles and media files, but I can't see any index of all the articles it have dumped, so I can't navigate in the dump. Reading about the XML dump feature MediaWiki have, I wonder if it would be possible to either use a program to view these files or perhaps convert them to html? Or are there other ways to make an offline version of a MediaWiki site?

  • From HttpRuntime.Cache to Windows Azure Caching (Preview)

    - by Jeff
    I don’t know about you, but the announcement of Windows Azure Caching (Preview) (yes, the parentheses are apparently part of the interim name) made me a lot more excited about using Azure. Why? Because one of the great performance tricks of any Web app is to cache frequently used data in memory, so it doesn’t have to hit the database, a service, or whatever. When you run your Web app on one box, HttpRuntime.Cache is a sweet and stupid-simple solution. Somewhere in the data fetching pieces of your app, you can see if an object is available in cache, and return that instead of hitting the data store. I did this quite a bit in POP Forums, and it dramatically cuts down on the database chatter. The problem is that it falls apart if you run the app on many servers, in a Web farm, where one server may initiate a change to that data, and the others will have no knowledge of the change, making it stale. Of course, if you have the infrastructure to do so, you can use something like memcached or AppFabric to do a distributed cache, and achieve the caching flavor you desire. You could do the same thing in Azure before, but it would cost more because you’d need to pay for another role or VM or something to host the cache. Now, you can use a portion of the memory from each instance of a Web role to act as that cache, with no additional cost. That’s huge. So if you’re using a percentage of memory that comes out to 100 MB, and you have three instances running, that’s 300 MB available for caching. For the uninitiated, a Web role in Azure is essentially a VM that runs a Web app (worker roles are the same idea, only without the IIS part). You can spin up many instances of the role, and traffic is load balanced to the various instances. It’s like adding or removing servers to a Web farm all willy-nilly and at your discretion, and it’s what the cloud is all about. I’d say it’s my favorite thing about Windows Azure. The slightly annoying thing about developing for a Web role in Azure is that the local emulator that’s launched by Visual Studio is a little on the slow side. If you’re used to using the built-in Web server, you’re used to building and then alt-tabbing to your browser and refreshing a page. If you’re just changing an MVC view, you’re not even doing the building part. Spinning up the simulated Azure environment is too slow for this, but ideally you want to code your app to use this fantastic distributed cache mechanism. So first off, here’s the link to the page showing how to code using the caching feature. If you’re used to using HttpRuntime.Cache, this should be pretty familiar to you. Let’s say that you want to use the Azure cache preview when you’re running in Azure, but HttpRuntime.Cache if you’re running local, or in a regular IIS server environment. Through the magic of dependency injection, we can get there pretty quickly. First, design an interface to handle the cache insertion, fetching and removal. Mine looks like this: public interface ICacheProvider {     void Add(string key, object item, int duration);     T Get<T>(string key) where T : class;     void Remove(string key); } Now we’ll create two implementations of this interface… one for Azure cache, one for HttpRuntime: public class AzureCacheProvider : ICacheProvider {     public AzureCacheProvider()     {         _cache = new DataCache("default"); // in Microsoft.ApplicationServer.Caching, see how-to      }         private readonly DataCache _cache;     public void Add(string key, object item, int duration)     {         _cache.Add(key, item, new TimeSpan(0, 0, 0, 0, duration));     }     public T Get<T>(string key) where T : class     {         return _cache.Get(key) as T;     }     public void Remove(string key)     {         _cache.Remove(key);     } } public class LocalCacheProvider : ICacheProvider {     public LocalCacheProvider()     {         _cache = HttpRuntime.Cache;     }     private readonly System.Web.Caching.Cache _cache;     public void Add(string key, object item, int duration)     {         _cache.Insert(key, item, null, DateTime.UtcNow.AddMilliseconds(duration), System.Web.Caching.Cache.NoSlidingExpiration);     }     public T Get<T>(string key) where T : class     {         return _cache[key] as T;     }     public void Remove(string key)     {         _cache.Remove(key);     } } Feel free to expand these to use whatever cache features you want. I’m not going to go over dependency injection here, but I assume that if you’re using ASP.NET MVC, you’re using it. Somewhere in your app, you set up the DI container that resolves interfaces to concrete implementations (Ninject call is a “kernel” instead of a container). For this example, I’ll show you how StructureMap does it. It uses a convention based scheme, where if you need to get an instance of IFoo, it looks for a class named Foo. You can also do this mapping explicitly. The initialization of the container looks something like this: ObjectFactory.Initialize(x =>             {                 x.Scan(scan =>                         {                             scan.AssembliesFromApplicationBaseDirectory();                             scan.WithDefaultConventions();                         });                 if (Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.IsAvailable)                     x.For<ICacheProvider>().Use<AzureCacheProvider>();                 else                     x.For<ICacheProvider>().Use<LocalCacheProvider>();             }); If you use Ninject or Windsor or something else, that’s OK. Conceptually they’re all about the same. The important part is the conditional statement that checks to see if the app is running in Azure. If it is, it maps ICacheProvider to AzureCacheProvider, otherwise it maps to LocalCacheProvider. Now when a request comes into your MVC app, and the chain of dependency resolution occurs, you can see to it that the right caching code is called. A typical design may have a call stack that goes: Controller –> BusinessLogicClass –> Repository. Let’s say your repository class looks like this: public class MyRepo : IMyRepo {     public MyRepo(ICacheProvider cacheProvider)     {         _context = new MyDataContext();         _cache = cacheProvider;     }     private readonly MyDataContext _context;     private readonly ICacheProvider _cache;     public SomeType Get(int someTypeID)     {         var key = "somename-" + someTypeID;         var cachedObject = _cache.Get<SomeType>(key);         if (cachedObject != null)         {             _context.SomeTypes.Attach(cachedObject);             return cachedObject;         }         var someType = _context.SomeTypes.SingleOrDefault(p => p.SomeTypeID == someTypeID);         _cache.Add(key, someType, 60000);         return someType;     } ... // more stuff to update, delete or whatever, being sure to remove // from cache when you do so  When the DI container gets an instance of the repo, it passes an instance of ICacheProvider to the constructor, which in this case will be whatever implementation was specified when the container was initialized. The Get method first tries to hit the cache, and of course doesn’t care what the underlying implementation is, Azure, HttpRuntime, or otherwise. If it finds the object, it returns it right then. If not, it hits the database (this example is using Entity Framework), and inserts the object into the cache before returning it. The important thing not pictured here is that other methods in the repo class will construct the key for the cached object, in this case “somename-“ plus the ID of the object, and then remove it from cache, in any method that alters or deletes the object. That way, no matter what instance of the role is processing the request, it won’t find the object if it has been made stale, that is, updated or outright deleted, forcing it to attempt to hit the database. So is this good technique? Well, sort of. It depends on how you use it, and what your testing looks like around it. Because of differences in behavior and execution of the two caching providers, for example, you could see some strange errors. For example, I immediately got an error indicating there was no parameterless constructor for an MVC controller, because the DI resolver failed to create instances for the dependencies it had. In reality, the NuGet packaged DI resolver for StructureMap was eating an exception thrown by the Azure components that said my configuration, outlined in that how-to article, was wrong. That error wouldn’t occur when using the HttpRuntime. That’s something a lot of people debate about using different components like that, and how you configure them. I kinda hate XML config files, and like the idea of the code-based approach above, but you should be darn sure that your unit and integration testing can account for the differences.

  • Get income on a free app, offline?

    - by user717572
    I have an Android app which I added adMob ads to. They only work tough when the user is online. Now the problem is, the app is specially made for offline use, so pretty much nobody will ever get to see one. The app is free to download, but I would still like to make a few cents out of it. It currently has around 300, which I guess will look at it about twice per workday. Any help on how to make some money with this free, offline app?

  • Elastic versus Distributed in caching.

    - by Mike Reys
    Until now, I hadn't heard about Elastic Caching yet. Today I read Mike Gualtieri's Blog entry. I immediately thought about Oracle Coherence and got a little scare throughout the reading. Elastic Caching is the next step after Distributed Caching. As we've always positioned Coherence as a Distributed Cache, I thought for a brief instance that Oracle had missed a new trend/technology. But then I started reading the characteristics of an Elastic Cache. Forrester definition: Software infrastructure that provides application developers with data caching services that are distributed across two or more server nodes that consistently perform as volumes grow can be scaled without downtime provide a range of fault-tolerance levels Hey wait a minute, doesn't Coherence fullfill all these requirements? Oh yes, I think it does! The next defintion in the article is about Elastic Application Platforms. This is mainly more of the same with the addition of code execution. Now there is analytics functionality in Oracle Coherence. The analytics capability provides data-centric functions like distributed aggregation, searching and sorting. Coherence also provides continuous querying and event-handling. I think that when it comes to providing an Elastic Application Platform (as in the Forrester definition), Oracle is close, nearly there. And what's more, as Elastic Platform is the next big thing towards the big C word, Oracle Coherence makes you cloud-ready ;-) There you go! Find more info on Oracle Coherence here.

  • How can I reduce the CPU usage of Offline Files?

    - by Diego
    Whenever I have the Offline Files service running, there is a constant 25% CPU usage on svchost.exe (this is a quad core, so that means it's using up one core). This, in turn, triples the power consumption and keeps the machine hot... I do have several GB synchronized (music collection), but they are not changing at all, in either side. Am I misusing this feature? Is there anything I can configure to keep it down when there's nothing to do? Or should I forget about it and synchronize big folders manually?

  • Server goes offline. What to look for?

    - by Jonathan Sampson
    I'm using a new virtual server through GoDaddy, and this morning I received a call from the powers that be informing me our website was offline. After confirming this, I requested a power cycle through our GoDaddy control panel, and within a minute or two the server was back online. I made the call, and reported the news that we're back up. Of course, a couple minutes later we're down again. I tried connecting through PuTTy, and it takes forever to prompt me for a username, and each successive prompt takes a long time to come up. I'm using CentOS. So my questions are: How can I determine the cause? What types of things can I do to prevent this in the future? One interesting, and perhaps relevant, observation is that yesterday our bandwidth consumption was about 20% greater than our top figures from the past month.

  • Windows Azure: Caching

    - by xamlnotes
    I was poking around today and found this great article on caching: http://www.cloudcomputingdevelopment.net/cache-management-with-windows-azure/ Caching is a great way to boost application performance and keep down overhead on a database or file system. Its also great when you have say 3 web roles as shown in this articles Figure 2 that can share the same cache. If one of the roles goes offline then the cache is still there and can be used. You can change out your asp.net caching to use this pretty easy. Its pretty cool. There’s a sample that’s mentioned in the article that shows how to use this. You can download the cache here.

  • Will small random dynamic snippets break caching

    - by Saif Bechan
    I am busy writing a WordPress plugin. Now most users have cache plugins installed, they cache the pages. I know also some webservers as nginx have php caching and whatnot. There are also things like memcached. Now I have to admit I do not know exactly how they work, if anyone have some good links on how they work I would be glad. Some links where it's explained simple, not to technical. Now the question. My plugin displays different statistics on posts, they are always different, will this break the caching of the page. To take is a step further, sometimes the statistics of the post needs updating, and there is a small javascript snippet added to the page. Now will these two action result in the page not caching, or am I ok.

  • More on PHP and Oracle 11gR2 Improvements to Client Result Caching

    - by christopher.jones
    Oracle 11.2 brought several improvements to Client Result Caching. CRC is way for the results of queries to be cached in the database client process for reuse.  In an Oracle OpenWorld presentation "Best Practices for Developing Performant Application" my colleague Luxi Chidambaran had a (non-PHP generated) graph for the Niles benchmark that shows a DB CPU reduction up to 600% and response times up to 22% faster when using CRC. Sometimes CRC is called the "Consistent Client Cache" because Oracle automatically invalidates the cache if table data is changed.  This makes it easy to use without needing application logic rewrites. There are a few simple database settings to turn on and tune CRC, so management is also easy. PHP OCI8 as a "client" of the database can use CRC.  The cache is per-process, so plan carefully before caching large data sets.  Tables that are candidates for caching are look-up tables where the network transfer cost dominates. CRC is really easy in 11.2 - I'll get to that in a moment.  It was also pretty easy in Oracle 11.1 but it needed some tiny application changes.  In PHP it was used like: $s = oci_parse($c, "select /*+ result_cache */ * from employees"); oci_execute($s, OCI_NO_AUTO_COMMIT); // Use OCI_DEFAULT in OCI8 <= 1.3 oci_fetch_all($s, $res); I blogged about this in the past.  The query had to include a specific hint that you wanted the results cached, and you needed to turn off auto committing during execution either with the OCI_DEFAULT flag or its new, better-named alias OCI_NO_AUTO_COMMIT.  The no-commit flag rule didn't seem reasonable to me because most people wouldn't be specific about the commit state for a query. Now in Oracle 11.2, DBAs can now nominate tables for caching, either with CREATE TABLE or ALTER TABLE.  That means you don't need the query hint anymore.  As well, the no-commit flag requirement has been lifted.  Your code can now look like: $s = oci_parse($c, "select * from employees"); oci_execute($s); oci_fetch_all($s, $res); Since your code probably already looks like this, your DBA can find the top queries in the database and simply tune the system by turning on CRC in the database and issuing an ALTER TABLE statement for candidate tables.  Voila. Another CRC improvement in Oracle 11.2 is that it works with DRCP connection pooling. There is some fine print about what is and isn't cached, check the Oracle manuals for details.  If you're using 11.1 or non-DRCP "dedicated servers" then make sure you use oci_pconnect() persistent connections.  Also in PHP don't bind strings in the query, although binding as SQLT_INT is OK.

  • Caching: the Good, the Bad and the Hype

    One of the more important aspects of the scalability of an ASP.NET site is caching. To do this effectively, one must understand the relative permanence and importance of the data that is presented to the user, and work out which of the four major aspects of caching should be used. There is always a compromise, but in most cases it is an easy compromise to make considering its effects in a heavily-loaded production system

  • Access Offline or Overloaded Webpages in Firefox

    - by Asian Angel
    What do you do when you really want to access a webpage only to find that it is either offline or overloaded from too much traffic? You can get access to the most recent cached version using the Resurrect Pages extension for Firefox. The Problem If you have ever encountered a website that has become overloaded and unavailable due to sudden popularity (i.e. Slashdot, Digg, etc.) then this is the result. No satisfaction to be had here… Resurrect Pages in Action Once you have installed the extension you can add the Toolbar Button if desired…it will give you the easiest access to Resurrect Pages. Or you can wait for a problem to occur when trying to access a particular website and have it appear as shown here. As you can see there is a very nice selection of cache services to choose from, therefore increasing your odds of accessing a copy of that webpage. If you would prefer to have the access attempt open in a new tab or window then you should definitely use the Toolbar Button. Clicking on the Toolbar Button will give you access to the popup window shown here…otherwise the access attempt will happen in the current tab. Here is the result for the website that we wanted to view using the Google Listing. Followed by the Google (text only) Listing. The results with the different services will depend on how recently the webpage was published/set up. View Older Versions of Currently Accessible Websites Just for fun we decided to try the extension out on the How-To Geek website to view an older version of the homepage. Using the Toolbar Button and clicking on The Internet Archive brought up the following page…we decided to try the Nov. 28, 2006 listing. As you can see things have really changed between 2006 and now…Resurrect Pages can be very useful for anyone who is interested in how websites across the web have grown and changed over the years. Conclusion If you encounter a webpage that is offline or overloaded by sudden popularity then the Resurrect Pages extension can help you get access to the information that you need using a cached version.
