  • How to configure DNS Server on Fedora

    - by user863873
    I want to learn how to configure my home PC server into a web server with domain and host. My IP is 109.99.141.133 and now points to a phpinfo page host on my home server. My registed domain is: anunta-anunturi.ro I searched for a tutorial and I've read that I have to configure /etc/named.conf and the file sources for the new zone that I create. So, from the tutorials, my /etc/named.conf looks like this: // // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { listen-on port 53 { 127.0.0.1; }; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; allow-query { localhost; }; recursion yes; dnssec-enable yes; dnssec-validation yes; dnssec-lookaside auto; /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "anunta-anunturi.ro" IN { type master; file "/etc/anunta-anunturi.db"; }; zone "." IN { type hint; file "named.ca"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; My /etc/anunta-anunturi.db file looks like this — I'm not sure if this is okay, or if it's the easy one. $TTL 86400 anunta-anunturi.ro. IN SOA serveur.anunta-anunturi.ro. root.serveur.anunta-anunturi.ro. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minumun IN NS serveur.anunta-anunturi.ro. IN MX 10 mail.anunta-anunturi.ro. serveur.anunta-anunturi.ro. IN A 192.168.1.37 www.anunta-anunturi.ro. IN A 192.168.1.37 mail.anunta-anunturi.ro. IN A 192.168.1.37 Extra info: At home I receive internet from my ISP through a router. My home PC and server recieve their IP automatically from the router when I start/restart. In my local home network, my server receives the IP 192.168.1.37 from the router. When I enter 109.99.141.133 in my browser, it points to the rooter that forwards port 80 to local IP 192.168.1.37 (my home server) Questions: Are my two files good? What/where is my nameserver that I need to copy/paste to my top level domain (where I registered my domain: rotld.ro)?

  • How to connect FreeBSD Jail to network

    - by jgtumusiime
    So recently I successfully installed and configured a freebsd jail and I would like to install software within my jail but I cannot connect to the network. I'm trying to setup an apache+php+mysql installation within the jail and have the webserver accessible by users. Here is my rc.conf for the jail. ... jail_enable="YES" # Set to NO to disable starting of any jails jail_list="mambo2" # Space separated list of names of jails jail_mambo2_rootdir="/usr/jails/j01" # jail's root directory jail_mambo2_hostname="mambo2.ug" # jail's hostname jail_mambo2_ip="192.168.100.174" # jail's IP address jail_mambo2_devfs_enable="YES" # mount devfs in the jail jail_mambo2_devfs_ruleset="mambo2_ruleset" # devfs ruleset to apply to jail here is my jail ifconfig output mambo2# ifconfig rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:c1:28:00:48:db media: Ethernet autoselect (100baseTX <full-duplex>) status: active plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 mambo2# It does not show the IP address I configured within /etc/rc.conf.

  • amplified reflected attack on dns

    - by Mike Janson
    The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim? This is a configuration issue right? my named conf file include "/etc/rndc.key"; controls { inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; }; }; options { /* make named use port 53 for the source of all queries, to allow * firewalls to block all ports except 53: */ // query-source port 53; /* We no longer enable this by default as the dns posion exploit has forced many providers to open up their firewalls a bit */ // Put files that named is allowed to write in the data/ directory: directory "/var/named"; // the default pid-file "/var/run/named/named.pid"; dump-file "data/cache_dump.db"; statistics-file "data/named_stats.txt"; /* memstatistics-file "data/named_mem_stats.txt"; */ allow-transfer {"none";}; }; logging { /* If you want to enable debugging, eg. using the 'rndc trace' command, * named will try to write the 'named.run' file in the $directory (/var/named"). * By default, SELinux policy does not allow named to modify the /var/named" directory, * so put the default debug log file in data/ : */ channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { /* This view sets up named to be a localhost resolver ( caching only nameserver ). * If all you want is a caching-only nameserver, then you need only define this view: */ match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; zone "."

  • Ruby on Rails: url_for :back leads to NoMethodError for back_url

    - by Platinum Azure
    Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

  • Motherboard/PSU crippling USB and Sata

    - by celebdor
    I very recently bought a new desktop computer. The motherboard is: Z77MX-D3H and the power supply is ocz zs series 550w. The issue I have is that once I boot to the operating system (I have tried with fedora and Ubuntu with kernels 2.6.38 - 3.4.0), my hard drive (2.5" Magnetic) occasionally makes a power switch noise and it resets. Needless to say, when this drive is the OS drive, the OS crashes. I also have a SSD that works fine with the same OS configurations, but if I have the magnetic hard drive attached as second drive, it works erratically and the reconnects result in corrupted data. I also noticed that whenever I plug an external hard drive USB2.0 or USB3.0 to the computer the issue with the reconnects is even worse: [ 52.198441] sd 7:0:0:0: [sdc] Spinning up disk...

Also the issue of the usb reconnects is less frequent if the hard drive is plugged before I switch on the computer. Does anybody have some advice as to what I could do? Which is the faulty part/s that I should replace? As for me, I really don't know if to point my finger to the PSU or the Motherboard (I have updated to the latest firmware and checked the BIOS settings several times). EDIT: The reconnects are happening both in the Sata connected drives and the USBX connected drives.

  • Auto-hydrate your objects with ADO.NET

    - by Jake Rutherford
    Recently while writing the monotonous code for pulling data out of a DataReader to hydrate some objects in an application I suddenly wondered "is this really necessary?" You've probably asked yourself the same question, and many of you have: - Used a code generator - Used a ORM such as Entity Framework - Wrote the code anyway because you like busy work     In most of the cases I've dealt with when making a call to a stored procedure the column names match up with the properties of the object I am hydrating. Sure that isn't always the case, but most of the time it's 1 to 1 mapping.  Given that fact I whipped up the following method of hydrating my objects without having write all of the code. First I'll show the code, and then explain what it is doing.      /// <summary>     /// Abstract base class for all Shared objects.     /// </summary>     /// <typeparam name="T"></typeparam>     [Serializable, DataContract(Name = "{0}SharedBase")]     public abstract class SharedBase<T> where T : SharedBase<T>     {         private static List<PropertyInfo> cachedProperties;         /// <summary>         /// Hydrates derived class with values from record.         /// </summary>         /// <param name="dataRecord"></param>         /// <param name="instance"></param>         public static void Hydrate(IDataRecord dataRecord, T instance)         {             var instanceType = instance.GetType();                         //Caching properties to avoid repeated calls to GetProperties.             //Noticable performance gains when processing same types repeatedly.             if (cachedProperties == null)             {                 cachedProperties = instanceType.GetProperties().ToList();             }                         foreach (var property in cachedProperties)             {                 if (!dataRecord.ColumnExists(property.Name)) continue;                 var ordinal = dataRecord.GetOrdinal(property.Name);                 var isNullable = property.PropertyType.IsGenericType &&                                  property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>);                 var isNull = dataRecord.IsDBNull(ordinal);                 var propertyType = property.PropertyType;                 if (isNullable)                 {                     if (!string.IsNullOrEmpty(propertyType.FullName))                     {                         var nullableType = Type.GetType(propertyType.FullName);                         propertyType = nullableType != null ? nullableType.GetGenericArguments()[0] : propertyType;                     }                 }                 switch (Type.GetTypeCode(propertyType))                 {                     case TypeCode.Int32:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt32(ordinal), null);                         break;                     case TypeCode.Double:                         property.SetValue(instance,                                           (isNullable && isNull) ? (double?) null : dataRecord.GetDouble(ordinal),                                           null);                         break;                     case TypeCode.Boolean:                         property.SetValue(instance,                                           (isNullable && isNull) ? (bool?) null : dataRecord.GetBoolean(ordinal),                                           null);                         break;                     case TypeCode.String:                         property.SetValue(instance, (isNullable && isNull) ? null : isNull ? null : dataRecord.GetString(ordinal),                                           null);                         break;                     case TypeCode.Int16:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt16(ordinal), null);                         break;                     case TypeCode.DateTime:                         property.SetValue(instance,                                           (isNullable && isNull)                                               ? (DateTime?) null                                               : dataRecord.GetDateTime(ordinal), null);                         break;                 }             }         }     }   Here is a class which utilizes the above: [Serializable] [DataContract] public class foo : SharedBase<foo> {     [DataMember]     public int? ID { get; set; }     [DataMember]     public string Name { get; set; }     [DataMember]     public string Description { get; set; }     [DataMember]     public string Subject { get; set; }     [DataMember]     public string Body { get; set; }            public foo(IDataRecord record)     {         Hydrate(record, this);                }     public foo() {} }   Explanation: - Class foo inherits from SharedBase specifying itself as the type. (NOTE SharedBase is abstract here in the event we want to provide additional methods which could be overridden by the instance class) public class foo : SharedBase<foo> - One of the foo class constructors accepts a data record which then calls the Hydrate method on SharedBase passing in the record and itself. public foo(IDataRecord record) {      Hydrate(record, this); } - Hydrate method on SharedBase will use reflection on the object passed in to determine its properties. At the same time, it will effectively cache these properties to avoid repeated expensive reflection calls public static void Hydrate(IDataRecord dataRecord, T instance) {      var instanceType = instance.GetType();      //Caching properties to avoid repeated calls to GetProperties.      //Noticable performance gains when processing same types repeatedly.      if (cachedProperties == null)      {           cachedProperties = instanceType.GetProperties().ToList();      } . . . - Hydrate method on SharedBase will iterate each property on the object and determine if a column with matching name exists in data record foreach (var property in cachedProperties) {      if (!dataRecord.ColumnExists(property.Name)) continue;      var ordinal = dataRecord.GetOrdinal(property.Name); . . . NOTE: ColumnExists is an extension method I put on IDataRecord which I’ll include at the end of this post. - Hydrate method will determine if the property is nullable and whether the value in the corresponding column of the data record has a null value var isNullable = property.PropertyType.IsGenericType && property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>); var isNull = dataRecord.IsDBNull(ordinal); var propertyType = property.PropertyType; . . .  - If Hydrate method determines the property is nullable it will determine the underlying type and set propertyType accordingly - Hydrate method will set the value of the property based upon the propertyType   That’s it!!!   The magic here is in a few places. First, you may have noticed the following: public abstract class SharedBase<T> where T : SharedBase<T> This says that SharedBase can be created with any type and that for each type it will have it’s own instance. This is important because of the static members within SharedBase. We want this behavior because we are caching the properties for each type. If we did not handle things in this way only 1 type could be cached at a time, or, we’d need to create a collection that allows us to cache the properties for each type = not very elegant.   Second, in the constructor for foo you may have noticed this (literally): public foo(IDataRecord record) {      Hydrate(record, this); } I wanted the code for auto-hydrating to be as simple as possible. At first I wasn’t quite sure how I could call Hydrate on SharedBase within an instance of the class and pass in the instance itself. Fortunately simply passing in “this” does the trick. I wasn’t sure it would work until I tried it out, and fortunately it did.   So, to actually use this feature when utilizing ADO.NET you’d do something like the following:        public List<foo> GetFoo(int? fooId)         {             List<foo> fooList;             const string uspName = "usp_GetFoo";             using (var conn = new SqlConnection(_dbConnection))             using (var cmd = new SqlCommand(uspName, conn))             {                 cmd.CommandType = CommandType.StoredProcedure;                 cmd.Parameters.Add(new SqlParameter("@FooID", SqlDbType.Int)                                        {Direction = ParameterDirection.Input, Value = fooId});                 conn.Open();                 using (var dr = cmd.ExecuteReader())                 {                     fooList= (from row in dr.Cast<DbDataRecord>()                                             select                                                 new foo(row)                                            ).ToList();                 }             }             return fooList;         }   Nice! Instead of having line after line manually assigning values from data record to an object you simply create a new instance and pass in the data record. Note that there are certainly instances where columns returned from stored procedure do not always match up with property names. In this scenario you can still use the above method and simply do your manual assignments afterward.

  • Optimal storage of data structure for fast lookup and persistence

    - by Mikael Svenson
    Scenario I have the following methods: public void AddItemSecurity(int itemId, int[] userIds) public int[] GetValidItemIds(int userId) Initially I'm thinking storage on the form: itemId -> userId, userId, userId and userId -> itemId, itemId, itemId AddItemSecurity is based on how I get data from a third party API, GetValidItemIds is how I want to use it at runtime. There are potentially 2000 users and 10 million items. Item id's are on the form: 2007123456, 2010001234 (10 digits where first four represent the year). AddItemSecurity does not have to perform super fast, but GetValidIds needs to be subsecond. Also, if there is an update on an existing itemId I need to remove that itemId for users no longer in the list. I'm trying to think about how I should store this in an optimal fashion. Preferably on disk (with caching), but I want the code maintainable and clean. If the item id's had started at 0, I thought about creating a byte array the length of MaxItemId / 8 for each user, and set a true/false bit if the item was present or not. That would limit the array length to little over 1mb per user and give fast lookups as well as an easy way to update the list per user. By persisting this as Memory Mapped Files with the .Net 4 framework I think I would get decent caching as well (if the machine has enough RAM) without implementing caching logic myself. Parsing the id, stripping out the year, and store an array per year could be a solution. The ItemId - UserId[] list can be serialized directly to disk and read/write with a normal FileStream in order to persist the list and diff it when there are changes. Each time a new user is added all the lists have to updated as well, but this can be done nightly. Question Should I continue to try out this approach, or are there other paths which should be explored as well? I'm thinking SQL server will not perform fast enough, and it would give an overhead (at least if it's hosted on a different server), but my assumptions might be wrong. Any thought or insights on the matter is appreciated. And I want to try to solve it without adding too much hardware :) [Update 2010-03-31] I have now tested with SQL server 2008 under the following conditions. Table with two columns (userid,itemid) both are Int Clustered index on the two columns Added ~800.000 items for 180 users - Total of 144 million rows Allocated 4gb ram for SQL server Dual Core 2.66ghz laptop SSD disk Use a SqlDataReader to read all itemid's into a List Loop over all users If I run one thread it averages on 0.2 seconds. When I add a second thread it goes up to 0.4 seconds, which is still ok. From there on the results are decreasing. Adding a third thread brings alot of the queries up to 2 seonds. A forth thread, up to 4 seconds, a fifth spikes some of the queries up to 50 seconds. The CPU is roofing while this is going on, even on one thread. My test app takes some due to the speedy loop, and sql the rest. Which leads me to the conclusion that it won't scale very well. At least not on my tested hardware. Are there ways to optimize the database, say storing an array of int's per user instead of one record per item. But this makes it harder to remove items.

  • Why don't I just build the whole web app in Javascript and Javascript HTML Templates?

    - by viatropos
    I'm getting to the point on an app where I need to start caching things, and it got me thinking... In some parts of the app, I render table rows (jqGrid, slickgrid, etc.) or fancy div rows (like in the New Twitter) by grabbing pure JSON and running it through something like Mustache, jquery.tmpl, etc. In other parts of the app, I just render the info in pure HTML (server-side HAML templates), and if there's searching/paginating, I just go to a new URL and load a new HTML page. Now the problem is in caching and maintainability. On one hand I'm thinking, if everything was built using Javascript HTML Templates, then my app would serve just an HTML layout/shell, and a bunch of JSON. If you look at the Facebook and Twitter HTML source, that's basically what they're doing (95% json/javascript, 5% html). This would make it so my app only needed to cache JSON (pages, actions, and/or records). Which means you'd hit the cache no matter if you were some remote api developer accessing a JSON api, or the strait web app. That is, I don't need 2 caches, one for the JSON, one for the HTML. That seems like it'd cut my cache store down in half, and streamline things a little bit. On the other hand, I'm thinking, from what I've seen/experienced, generating static HTML server-side, and caching that, seems to be much better performance wise cross-browser; you get the graphics instantly and don't have to wait that split-second for javascript to render it. StackOverflow seems to do everything in plain HTML, and you can tell... everything appears at once. Notice how though on twitter.com, the page is blank for .5-1 seconds, and the page chunks in: the javascript has to render the json. The downside with this is that, for anything dynamic (like endless scrolling, or grids), I'd have to create javascript templates anyway... so now I have server-side HAML templates, client-side javascript templates, and a lot more to cache. My question is, is there any consensus on how to approach this? What are the benefits and drawbacks from your experience of mixing the two versus going 100% with one over the other? Update: Some reasons that factor into why I haven't yet made the decision to go with 100% javascript templating are: Performance. Haven't formally tested, but from what I've seen, raw html renders faster and more fluidly than javascript-generated html cross-browser. Plus, I'm not sure how mobile devices handle dynamic html performance-wise. Testing. I have a lot of integration tests that work well with static HTML, so switching to javascript-only would require 1) more focused pure-javascript testing (jasmine), and 2) integrating javascript into capybara integration tests. This is just a matter of time and work, but it's probably significant. Maintenance. Getting rid of HAML. I love HAML, it's so easy to write, it prints pretty HTML... It makes code clean, it makes maintenance easy. Going with javascript, there's nothing as concise. SEO. I know google handles the ajax /#!/path, but haven't grasped how this will affect other search engines and how older browsers handle it. Seems like it'd require a significant setup.

  • A view interface for large object/array dumps

    - by user685107
    I want to embed in a page a detailed structure report of my model objects, like print_r() or var_export() produce (now I’m doing this with running var_export() on get_object_vars()). But what I actually want to see is only some properties (in most cases), but at this moment I have to use Ctrl+F and seek the variable I want, instead of just staring at it right after the page completes loading. So I’m embedding buttons to show/hide large arrays etc. but thought: ‘What if there already is the thing I do right now?’ So is there? Update: What would your ideal interface look like? First of all, dumped models fit in the first screen. All the properties can be seen at the first look at the screen (there are not many of them, around 10 per each, three models total, so it is possible). Small arrays can be shown unrolled too. Let the size of the array to count it as ‘small’ be definable. Ideally, the user can see values of the properties without doing any click, scrolling the screen or typing something. There must be some improvements to representing the values, say, if an array is empty, show array ‘My_big_array’ is empty and if a boolean variable starting with is_, has_, had_ has a false as the value, make the variable (let us take is_available for example) shown as is_NOT_available in red, and if it has true as the value, show is_available in green. Without any value shown. The same goes for defined constants. That would be ideal. I want to make focus on this kind of switches. Krumo seems useful, but since it always closes up the variable without making difference of how large it is, I cannot use it as is, but there might appear something similar on github soon :) Second update starts here: Any programmer who sees is_available = false will know what it means, no need to do more Bringing in color indication I forgot about one thing: the ‘switches’ let’s call them so, may me important or not. So I have right now some of them that will show in green or red, this is for something global, like caching, which is shown as Caching is… ON with ‘ON’ written in green, (and ‘OFF’ in red when disabled) while the words about what it is, i.e. ‘Caching is… ’ are written in black. And some which are not so important, for example I haven’t defined REVEAL_TIES is… not set with ‘not set’ written in gray, while the words describing what it is stay in black. And if it would be set the whole phrase would be in black since there is nothing important: if this small utility for showing some undercover things is working, I will see some messages after it, if it isn’t — site will be working independently of its state. Dividing switches into important ones and not with corresponding color match should improve readability, especially for those users who are not programmers and just enabled debug mode because some guy from bugzilla said do that — for them it would help to understand what is important and what is not.

  • Replacing ASP.NET Forms Authentication with WIF Session Authentication (for the better)

    ASP.NET Forms Authentication and WIF Session Authentication (which has *nothing* to do with ASP.NET sessions) are very similar. Both inspect incoming requests for a special cookie that contains identity information, if that cookie is present it gets validated and if that is successful, the identity information is made available to the application via HttpContext.User/Thread.CurrentPrincipal. The main difference between the two is the identity to cookie serialization engine that sits below. Whereas ForsmAuth can only store the name of the user and an additional UserData string. It is limited to a single cookie and hardcoded to protection via the machine key. WIF session authentication in turn has these additional features: Can serialize a complete ClaimsPrincipal (including claims) to the cookie(s). Has a cookie overflow mechanism when data gets too big. In total it can create up to 8 cookies (á 4 KB) per domain (not that I would recommend round tripping that much data). Supports server side caching (which is an extensible mechanism). Has an extensible mechanism for protection (DPAPI by default, RSA as an option for web farms, and machine key based protection is coming in .NET 4.5) So in other words – session authentication is the superior technology, and if done cleverly enough you can replace FormsAuth without any changes to your application code. The only features missing is the redirect mechanism to a login page and an easy to use API to set authentication cookies. But that’s easy to add ;) FormsSessionAuthenticationModule This module is a sub class of the standard WIF session module, adding the following features: Handling EndRequest to do the redirect on 401s to the login page configured for FormsAuth. Reads the FormsAuth cookie name, cookie domain, timeout and require SSL settings to configure the module accordingly. Implements sliding expiration if configured for FormsAuth. It also uses the same algorithm as FormsAuth to calculate when the cookie needs renewal. Implements caching of the principal on the server side (aka session mode) if configured in an AppSetting. Supports claims transformation via a ClaimsAuthenticationManager. As you can see, the whole module is designed to easily replace the FormsAuth mechanism. Simply set the authentication mode to None and register the module. In the spirit of the FormsAuthentication class, there is also now a SessionAuthentication class with the same methods and signatures (e.g. SetAuthCookie and SignOut). The rest of your application code should not be affected. In addition the session module looks for a HttpContext item called “NoRedirect”. If that exists, the redirect to the login page will *not* happen, instead the 401 is passed back to the client. Very useful if you are implementing services or web APIs where you want the actual status code to be preserved. A corresponding UnauthorizedResult is provided that gives you easy access to the context item. The download contains a sample app, the module and an inspector for session cookies and tokens. Let’s hope that in .NET 4.5 such a module comes out of the box. HTH

  • PC to USB transfer slow

    - by Vipin Ms
    I'm having trouble with USB transfer,not with external hard disk. Transfer starts with like, for the transfer of 700MB file it starts with 30mb/s and towards the end it stops at 0s and stays put for like 3-4 mins to transfer the last bit. I have tried different USB devices, but no luck. Is it a bug? Another important point is, in Kubuntu there is no such issue. So is it something related to Gnome? I'm using Ubuntu 11.10 64bit.

  • Windows Azure Recipe: Social Web / Big Media

    - by Clint Edmonson
    With the rise of social media there’s been an explosion of special interest media web sites on the web. From athletics to board games to funny animal behaviors, you can bet there’s a group of people somewhere on the web talking about it. Social media sites allow us to interact, share experiences, and bond with like minded enthusiasts around the globe. And through the power of software, we can follow trends in these unique domains in real time. Drivers Reach Scalability Media hosting Global distribution Solution Here’s a sketch of how a social media application might be built out on Windows Azure: Ingredients Traffic Manager (optional) – can be used to provide hosting and load balancing across different instances and/or data centers. Perfect if the solution needs to be delivered to different cultures or regions around the world. Access Control – this service is essential to managing user identity. It’s backed by a full blown implementation of Active Directory and allows the definition and management of users, groups, and roles. A pre-built ASP.NET membership provider is included in the training kit to leverage this capability but it’s also flexible enough to be combined with external Identity providers including Windows LiveID, Google, Yahoo!, and Facebook. The provider model has extensibility points to hook into other identity providers as well. Web Role – hosts the core of the web application and presents a central social hub users. Database – used to store core operational, functional, and workflow data for the solution’s web services. Caching (optional) – as a web site traffic grows caching can be leveraged to keep frequently used read-only, user specific, and application resource data in a high-speed distributed in-memory for faster response times and ultimately higher scalability without spinning up more web and worker roles. It includes a token based security model that works alongside the Access Control service. Tables (optional) – for semi-structured data streams that don’t need relational integrity such as conversations, comments, or activity streams, tables provide a faster and more flexible way to store this kind of historical data. Blobs (optional) – users may be creating or uploading large volumes of heterogeneous data such as documents or rich media. Blob storage provides a scalable, resilient way to store terabytes of user data. The storage facilities can also integrate with the Access Control service to ensure users’ data is delivered securely. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training These links point to online Windows Azure training labs and resources where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together.

  • CacheAdapter 2.4 – Bug fixes and minor functional update

    - by Glav
    Note: If you are unfamiliar with the CacheAdapter library and what it does, you can read all about its awesome ability to utilise memory, Asp.Net Web, Windows Azure AppFabric and memcached caching implementations via a single unified, simple to use API from here and here.. The CacheAdapter library is receiving an update to version 2.4 and is currently available on Nuget here. Update: The CacheAdapter has actualy just had a minor revision to 2.4.1. This significantly increases the performance and reliability in memcached scenario under more extreme loads. General to moderate usage wont see any noticeable difference though. Bugs This latest version fixes a big that is only present in the memcached implementation and is only seen in rare, intermittent times (making i particularly hard to find). The bug is where a cache node would be removed from the farm when errors in deserialization of cached objects would occur due to serialised data not being read from the stream in entirety. The code also contains enhancements to better surface serialization exceptions to aid in the debugging process. This is also specifically targeted at the memcached implementation. This is important when moving from something like memory or Asp.Web caching mechanisms to memcached where the serialization rules are not as lenient. There are a few other minor bug fixes, code cleanup and a little refactoring. Minor feature addition In addition to this bug fix, many people have asked for a single setting to either enable or disable the cache.In this version, you can disable the cache by setting the IsCacheEnabled flag to false in the application configuration file. Something like the example below: <Glav.CacheAdapter.MainConfig> <setting name="CacheToUse" serializeAs="String"> <value>memcached</value> </setting> <setting name="DistributedCacheServers" serializeAs="String"> <value>localhost:11211</value> </setting> <setting name="IsCacheEnabled" serializeAs="String"> <value>False</value> </setting> </Glav.CacheAdapter.MainConfig> Your reasons to use this feature may vary (perhaps some performance testing or problem diagnosis). At any rate, disabling the cache will cause every attempt to retrieve data from the cache, resulting in a cache miss and returning null. If you are using the ICacheProvider with the delegate/Func<T> syntax to populate the cache, this delegate method will get executed every single time. For example, when the cache is disabled, the following delegate/Func<T> code will be executed every time: var data1 = cacheProvider.Get<SomeData>("cache-key", DateTime.Now.AddHours(1), () => { // With the cache disabled, this data access code is executed every attempt to // get this data via the CacheProvider. var someData = new SomeData() { SomeText = "cache example1", SomeNumber = 1 }; return someData; }); One final note: If you access the cache directly via the ICache instance, instead of the higher level ICacheProvider API, you bypass this setting and still access the underlying cache implementation. Only the ICacheProvider instance observes the IsCacheEnabled setting. Thanks to those individuals who have used this library and provided feedback. Ifyou have any suggestions or ideas, please submit them to the issue register on bitbucket (which is where you can grab all the source code from too)

  • Windows Azure Recipe: Consumer Portal

    - by Clint Edmonson
    Nearly every company on the internet has a web presence. Many are merely using theirs for informational purposes. More sophisticated portals allow customers to register their contact information and provide some level of interaction or customer support. But as our understanding of how consumers use the web increases, the more progressive companies are taking advantage of social web and rich media delivery to connect at a deeper level with the consumers of their goods and services. Drivers Cost reduction Scalability Global distribution Time to market Solution Here’s a sketch of how a Windows Azure Consumer Portal might be built out: Ingredients Web Role – this will host the core of the solution. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control (optional) – if identity needs to be tracked within the solution, the access control service combined with the Windows Identity Foundation framework provides out-of-the-box support for several social media platforms including Windows LiveID, Google, Yahoo!, Facebook. It also has a provider model to allow integration with other platforms as well. Caching (optional) – for sites with high traffic with lots of read-only data and lists, the distributed in-memory caching service can be used to cache and serve up static data at higher scale and speed than direct database requests. It can also be used to manage user session state. Blob Storage (optional) – for sites that serve up unstructured data such as documents, video, audio, device drivers, and more. The data is highly available and stored redundantly across data centers. Each entry in blob storage is provided with it’s own unique URL for direct access by the browser. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content.

  • AppFabric Cache - An existing connection was forcibly closed by the remote host

  • Where does lucene .net cache the search results?

    - by Lanceomagnifico
    Hi, I'm trying to figure out where Lucene stores the cached query results, and how it's configured to do so - and how long it caches for. This is for an ASP.NET 3.5 solution. I'm getting this problem: If I run a search and sort the result by a particular product field, it seems to work the very first time each search and sort combination is used. If I then go in and change some product attributes, reindex and run the same search and sort, I get the products returned in the same order as the very first result. example Product A is named: foo Product B is named: bar For the first search, sort by name desc. This results in: Product A Product B Now mix up the data a bit: Change names to: Product A named: bar Product B named: foo reindex verify that the index contains the changes for these two products. search Result: Product A Product B Since I changed the alphabetical order of the names, I expected: Product B Product A So I think that Lucene is caching the search results. (Which, btw, is a very good thing.) I just need to know where/how to clear these results. I've tried deleting the index files and doing an IISreset to clear the memory, but it seems to have no effect. So I'm thinking there is another set of Lucene files outside of the indexes that Lucene uses for caching. EDIT I just found out that you must create the index for field you wish to sort on as un-tokenized. I had the field as tokenized, so sorting didn't work.

  • Terrible DotNetNuke performance

    - by Peter Bridger
    I'm involved with a project using DotNetNuke version 05.01.04 Community Edition. We are building our new Intranet using it, but performance is terrible. We have five people adding pages and content to it and every 15-30 seconds they experience a pause of 10 seconds or longer before the system continues and the next screens loads. The server is Windows 2003, 3.8GHz with 1GB of RAM. I'm told by our server admin that the CPU and memory performance don't appear to be the bottleneck. We currently have 350 pages in the system, we a plan to add 1000. So we need to resolve this performance problem so that we can enter content and so we can go live. I just can't see where the bottleneck is. Is there a good why to determine the bottleneck when using DotNetNuke? Modules installed Publish:Engage (Not currently in use) Page Blaster (Doesn't appear to providing caching when users logged in using Integrated Authentication) SimpleGallery XMod Content Manager IIS Setup Application recycling completely disabled (Apart from a 2am recycle) New findings: 18th March 2010 The main bottleneck was due to version 5.1.4 having a bug which caused 1300 database roundtrips on an average page, due to broken database in-memory caching. We've upgraded to 5.2.4 which has resolved this bottleneck. Now the next biggest bottleneck is the navigation. We've used both DDR:Menu and DDN:Nav, but both have a major impact on performance. Is there a navigation interface out there that doesn't drain performance so badly?

  • Optimizing PHP require_once's for low disk i/o?

    - by buggedcom
    Q1) I'm designing a CMS (-who isn't!) but priority is being given to caching. Literally everything is cached. DB rows, DB id queries, Configuration data, processed data, compiled templates. Currently it has two layers of caching. The first is a opcode cache or memory cache such as apc, eaccelerator, xcache or memcached. If an entry is not found in there it is then searched for in the secondary slow cache, ie php includes. Are the opcode caches actually faster than doing a require_once to a php file with a var_export'd array of data in it? My tests are inconclusive as my development box (5.3 of XAMPP) keeps throwing errors installing any of the aforementioned programs. Q2) The CMS has numerous helper classes that are autoloaded on demand instead of loading all files. Mostly each has a require before it so no autoloading needs to take place, however this is not the question. Because a page script can have up to 50/60 helper files included I have a feeling that if the site was under pressure it would buckle because of all the i/o that this incurs. Ignore for the moment that there is output cache in place that would remove the need for what I am about to suggest, and also that opcode caches would render this moot. What I have tried to do is join all the helper files required for the scripts execution in one single file. This is achievable and works well, however it has a side effect of greatly increasing the memory usage dramatically even though technically the same code is being used. What are your thoughts and opinions on this?

  • HashMap key problems

    - by Peterdk
    I'm profiling some old java code and it appears that my caching of values using a static HashMap and a access method does not work. Caching code (a bit abstracted): static HashMap<Key, Value> cache = new HashMap<Key, Value>(); public static Value getValue(Key key){ System.out.println("cache size="+ cache.size()); if (cache.containsKey(key)) { System.out.println("cache hit"); return cache.get(key); } else { System.out.println("no cache hit"); Value value = calcValue(); cache.put(key, value); return value; } } Profiling code: for (int i = 0; i < 100; i++) { getValue(new Key()); } Result output: cache size=0 no cache hit (..) cache size=99 no cache hit It looked like a standard error in Key's hashing code or equals code. However: new Key().hashcode == new Key().hashcode // TRUE new Key().equals(new Key()) // TRUE What's especially weird is that cache.put(key, value) just adds another value to the hashmap, instead of replacing the current one. So, I don't really get what's going on here. Am I doing something wrong?
