  • The Open Data Protocol

    - by Bobby Diaz
    Well, day 2 of the MIX10 conference did not disappoint.  The keynote speakers introduced the preview release of IE9, which looks really cool and quick, and Visual Studio 2010 RC that is scheduled to RTM on April 12th.  It seemed to have a lot of improvements aimed at making developers more productive.  Here are the current links to these two offerings: Internet Explorer 9 – Platform Preview Visual Studio 2010 and .NET 4 – Release Candidate While both of these were interesting, the demos that really blew me away today centered around the work being done with The Open Data Protocol, or OData for short!  OData is a recommended standard being pushed by Microsoft that uses a REST based interface to interact with various types of data in a uniform manner.  Data producers then provide the data to consumer in either ATOM or JSON formats as requested by the client application. The OData SDK contains client and server libraries for many of the popular languages in use today, including .NET, Java, PHP, Objective C and JavaScript, so you consume or even produce your own OData services.  More information can be found using the following links: OData.org How to navigate an OData compliant service Query Functions (WCF Data Services) Netflix has made available one of the first live OData services by exposing their entire movie catalog.  You can browse and query using URLs similar to the following: http://odata.netflix.com/ http://odata.netflix.com/Catalog/Genres('Horror')/CatalogTitles http://odata.netflix.com/Catalog/CatalogTitles?$filter=startswith(Title/Regular,%20'Star%20Wars')&$orderby=Title/Regular So now I just need to find an excuse reason to start using OData in a real project! Enjoy!

  • July, the 31 Days of SQL Server DMO’s – Day 27 (sys.dm_db_file_space_usage)

    - by Tamarick Hill
    The sys.dm_db_file_space usage DMV returns information about database file space usage.  This DMV was enhanced for the 2012 version to include 3 additional columns. Let’s query this DMV against our AdventureWorks2012 database and view the results. SELECT * FROM sys.dm_db_file_space_usage The column returned from this DMV are really self-explanatory, but I will give you a description, paraphrased from books online, below. The first three columns returned from this DMV represent the Database, File, and Filegroup for the current database context that executed the DMV query. The next column is the total_page_count which represents the total number of pages in the file. The allocated_extent_page_count represents the total number of pages in all extents that have been allocated. The unallocated_extent_page_count represents the number of pages in the unallocated extents within the file. The version_store_reserved_page_count column represents the number of pages that are allocated to the version store. The user_object_reserved_page_count represents the number of pages allocated for user objects. The internal_object_reserved_page_count represents the number of pages allocated for internal objects.  Lastly is the mixed_extent_page_count which represents the total number of pages that are part of mixed extents. This is a great DMV for retrieving usage space information from your database files. For more information about this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms174412.aspx Follow me on Twitter @PrimeTimeDBA

  • 5 Useful Wordpress Plugins For Google Adsense

    - by Jyoti
    Google Adsense has become the most popular online contextual advertising program and proper custom integration with Wordpress can help to increase Adsense earnings. Now on this post we have describe 5 useful wordpress plugin for google adsense. Few weeks ago we did a "10 Wordpress Plugins For Google Adsense ". Wordpress allows bloggers to easily integrate Google Adsense inside wordpress using plugins. Adsense Integrator : The Adsense Integrator plugin supports lot of programs other then adsense like AdBrite, AffiliateBOT, SHAREASALE, LinkShare, ClickBank, Oxado, Adpinion, AdGridWork, Adroll, Commission Junction, CrispAds, ShoppingAds, Yahoo!PN so this can be used when you are looking to have adsense as well as other alternatives. The rest of the features of the plugin are same where you give your adsense code into options field and it get inserted into blog posts. All In One Adsense And YPN : This is one of the most powerful adsense plugin for wordpress. Jut like other plugins, you can use this to insert your ads in the post but the plugin has some really good features like randomness which shows ad at random location in your blog which reduces ad blindness for viewers. You can also stop ads being shown on some pages using tags. Adsense Now : Other then the previous plugins , you can also give it a try to Adsense now. I haven’t used it (I have only used the first two) so its difficult to comment on it. It looks to be a lightweight plugin which insert adsense ads between posts and in posts body. Adsense Manager : Adsense Manager is one of the most popular and used plugin to manage adsense in wordpress blogs. Infact its newer version not only supports adsense, it also supports various other programs like adbrite, Commission Junction, YPN etc which makes it very powerful ad management plugin. You can inject adsense code anywhere in your blog posts as well as can put in different regions of your blog. Easy Adsense : Easy adsense is one of the new wordpress adsense plugin and that is why more feature rich. You can have different code for different themes using this plugin. It also support link units. To know all features, check out the plugin page.

  • LINQ: Enhancing Distinct With The PredicateEqualityComparer

    - by Paulo Morgado
    Today I was writing a LINQ query and I needed to select distinct values based on a comparison criteria. Fortunately, LINQ’s Distinct method allows an equality comparer to be supplied, but, unfortunately, sometimes, this means having to write custom equality comparer. Because I was going to need more than one equality comparer for this set of tools I was building, I decided to build a generic equality comparer that would just take a custom predicate. Something like this: public class PredicateEqualityComparer<T> : EqualityComparer<T> { private Func<T, T, bool> predicate; public PredicateEqualityComparer(Func<T, T, bool> predicate) : base() { this.predicate = predicate; } public override bool Equals(T x, T y) { if (x != null) { return ((y != null) && this.predicate(x, y)); } if (y != null) { return false; } return true; } public override int GetHashCode(T obj) { if (obj == null) { return 0; } return obj.GetHashCode(); } } Now I can write code like this: .Distinct(new PredicateEqualityComparer<Item>((x, y) => x.Field == y.Field)) But I felt that I’d lost all conciseness and expressiveness of LINQ and it doesn’t support anonymous types. So I came up with another Distinct extension method: public static IEnumerable<TSource> Distinct<TSource>(this IEnumerable<TSource> source, Func<TSource, TSource, bool> predicate) { return source.Distinct(new PredicateEqualityComparer<TSource>(predicate)); } And the query is now written like this: .Distinct((x, y) => x.Field == y.Field) Looks a lot better, doesn’t it?

  • Bind9 virtual subdomains

    - by Steffan
    I am trying to setup virtual subdomains using Bind9, following this tutorial.. http://groups.drupal.org/node/16862 which I've completed. Basically setting up the zone and modifying the resolv.conf file and the named.conf.local file. I've gotten everything to work, and I am able to from my server ping mydomain.com , test.mydomain.com and when i do a dig I get the following.. ; <<>> DiG 9.7.0-P1 <<>> test.mydomain.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32606 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;test.mydomain.com. IN A ;; ANSWER SECTION: test.mydomain.com. 86400 IN A 174.###.###.# ;; AUTHORITY SECTION: mydomain.com. 86400 IN NS mydomain.com. ;; ADDITIONAL SECTION: mydomain.com. 86400 IN A 174.###.###.# ;; Query time: 0 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Wed Jan 19 21:06:01 2011 ;; MSG SIZE rcvd: 86 So it looks like everything is working. However, when I try and do test.mydomain.com in the browser, expecting it to default for now to mydomain.com it does not work and I get a server not found page in Firefox. I did read elsewhere that in your virutalhosts file you also need to setup a *.mydomain.com alias, but that didn't fix anything. Any other information that I could provide to help troubleshoot, or any troubleshooting suggestions? I am using Ubuntu 10.4, with typical LAMP setup. The only other things installed on the server are Bind9 and ftp client.

  • Setting Timeouts: SQL Server 2008/IIS 7.5

    - by Julie
    We have recently migrated from a Win 2003/SQL Server 2000 system to Win 2008 64 bit R2, SQL Server 2008 R2. Our websites are in classic asp, and this can't be changed to another scripting language at this time. On the old server, if I got stuck in some kind of endless loop, the page would throw an error. On the new server, I have a page that has some sort of looping problem, that even though the SQL SP is called only once (and runs fine run as a query on the server) it pegs SQL server and therefore locks all of our websites. I'll get my code figured out, no biggie. But I need to make sure the server times out when this happens. (The page I'm working on runs fine with certain instances of the query, and locks with others using a different query variable. I can't have something like that sneak up on me on a page I haven't touched for three years.) I can't figure out how an SP that runs once on the server, from an ASP page, is tying up SQL server this way. It's obviously some sort of a timeout issue, but I can't figure out where/which timeout values to change. I actually have to remote desktop to the server and kill the process in SQL server. I'm afraid I'm a generalist, and server management is not my thing, even though it's my responsibility, so I am almost certain to have questions about any answer that I receive. How can I track this down? What settings do I need to change? More info: It's not SQL Server On our test site, I created an ASP file that just did an endless loop (do while 1=1) and had the same problem - the other websites wouldn't load - without SQL server being involved. So I think the reason the process was hanging is that the page wasn't timing out as it should, and so the connection to SQL was never closed. Killing the process in SQL server would reset the page somehow. For my intentional endless loop, I had to refresh the app pool to get rid of it. This points more to either IIS or the ASP settings. The ASP timeouts are set to whatever the default were when the server was first loaded. I still can't figure out why one file is locking up all websites, though. Again, that didn't happen on the old server.

  • Declarative programming vs. Imperative programming

    - by EpsilonVector
    I feel very comfortable with Imperative programming. I never have trouble expressing algorithmically what I want the computer to do once I figured out what is it that I want it to do. But when it comes to languages like SQL or Relational Algebra I often get stuck because my head is too used to Imperative programming. For example, suppose you have the relations band(bandName, bandCountry), venue(venueName, venueCountry), plays(bandName, venueName), and I want to write a query that says: all venueNames such that for every bandCountry there's a band from that country that plays in venue of that name. In my mind I immediately go "for each venueName iterate over all the bandCountries and for each bandCountry get the list of bands that come from it. If none of them play in venueName, go to next venueName. Else, at the end of the bandCountries iteration add venueName to the set of good venueNames". ...but you can't talk like that in SQL and I actually need to think about how to formulate this, with the intuitive Imperative solution constantly nagging in the back of my head. Did anybody else had this problem? How did you overcome this? Did you figured out a paradigm shift? Made a map from Imperative concepts to SQL concepts to translate Imperative solutions into Declarative ones? Read a good book? PS I'm not looking for a solution to the above query, I did solve it.

  • Cannot create a new domain in an existing active directory forest

    - by Mackenzie Carr
    I have a domain controller setup on Windows Server 2008 R2 (Forest) and I have another Windows Server 2008 R2 (New Domain) and I want to create a new domain in an existing forest. I get the following error: An Active Directory domain controller for the domain mackdev.mackenziecarr.com could not be contacted The error was "no records found for the given DNS query" The query was for the SRV record for: _ldap._tcp.dc._msdcs.mackdev.mackenziecarr.com I've seem to have tried everything even tried adding this record to the DNS server of the primary forest. I even successfully joined this server to the domain without any issues but trying to create a new domain under the existing forest is no luck. The primary forest I.P. address is 192.168.2.20 the server that I am using to try to make a child domain is 192.168.2.21 My ipconfig are as follows: I.P.

  • xVelocity engines compared: VertiPaq vs ColumnStore #ssas #vertipaq #xvelocity #sql #tabular

    - by Marco Russo (SQLBI)
    During the last months I and Alberto worked in several projects using Analysis Services Tabular and we had to face real world issues, such as complex queries, large data volume, frequent data updates and so on. Sometime we faced the challenge of comparing Tabular performance with SQL Server. It seemed a non-sense, because even if the same core xVelocity technology is implemented in both products (SQL Server 2012 uses ColumnStore indexes, whereas Analysis Services 2012 uses VertiPaq), we initially assumed that the better optimization for the in-memory engine used by Analysis Services would have been always better than SQL Server. However, we discovered several important things: Processing time might be different and having data on SQL Server could make ColumnStore way faster for processing. Partitioning in SQL Server might be much more effective for query performance than Analysis Services. A single query can scale easily on more processor on SQL Server, whereas in Analysis Services the formula engine is single-threaded and could be a bottleneck for certain queries. In case of a large workload with many concurrent users, storage engine cache in Analysis Services could be a big advantage over SQL Server, especially for scalability As you can see, these considerations are not always obvious and you might be tempted to make other assumptions based on these information. Well, don’t do that. Before anything else, read the whitepaper VertiPaq vs ColumnStore Comparison written by Alberto Ferrari. Then, measure your workload. Finally, make some conclusion. But don’t make too many assumptions. You might be wrong, as we did at the beginning of this journey.

  • Sprite sheet generator

    - by Andrea Tucci
    I need to generate a sprite sheet with squared sprite for a 2D game. How can I generate a sprite sheet where each frame has x = y? The only think I have to do is to "insert" some blank space between sprites (in case y were x in the original sprite). Is there any program that I can use to trasform "irregular" sprite sheets to "squared" sprite sheets? An example of non-squared sprite sheet: http://spriters-resource.com/gameboy_advance/khcom/sheet/1138

  • Check if user password input is valid in Powershell script

    - by Doltknuckle
    I am working with a Powershell script that adds scheduled tasks to systems in our domain. When I run this script, it will prompt me for my password. I sometimes fat finger the password and the process starts, which locks out my account. Is there a way to verify my credentials to make sure that what I typed in will validate with the Domain? I'd like to find a way to query the Domain controller. I've done some Google searches and I should be able to do a WMI query and trap for an error. I would like to avoid that style of validation if possible. Any ideas? Thanks in advance.

  • solr administration

    - by devrick0
    Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

  • Nano suddenly putting in weird characters when I type

    - by Cocorico
    I am using a shell and editing a file in nano (similar to pico). A short while ago, it started doing this thing where if I type: $query = "select" * from topics where id='' "; and then I hit Backspace and try to stick the letter 'a' into the id='' part, it changes it to: $query = "select * from koala_topics where id='a='' "; and the cursor jumps around to a few spaces before. Also if I type print At the start of a new line, and then I think "Oh I should have added a tab" and I go back and try to add a tab, it adds a tab AND 2 spaces, and if I put the cursor through the word print, it turns into printnt. Some other weird things have happened too. I uninstalled nano using yum (which is how I installed it), and then re-installed it, thinking that would get me clean preferences (in case that was the problem) but it doesn't fix it.

  • Why do Ping and Dig provide different IP address than nslookup?

    - by user1032531
    When pinging my domain name which points to my home public IP from two different servers on my LAN, it shows them pinging different IP. Further investigation shows dig and nslookup providing different results. See below. A little history. My IP used to be 11.22.33.444 and is hosted by Comcast. I changed routers, and it somehow got changed to 55.66.77.888. I've since updated my 1and1 domain name to point to the 55.66.77.888. desktop is a basic server, runs the web server, and connects wirelessly to my LAN. laptop is a GUI and connected via CAT5. Both operate Centos6.4. My old router was a D-Link, and used their "Virtual Server" feature to pass port 80 to desktop. My new router is a Linksys, and I use their "Port Forwarding" feature to pass port 80 to desktop (however, I haven't gotten this part working yet). What is going on??? Why the different IPs? Obviously, it most somehow be stored on the server, but why does the actual machine even know the public IP since it is on a LAN? How do I purge the old IP?

  • PowerDNS 3+ - Recursive queries for subdomains

    - by PDNS Troubles
    We are trying to find functionality in the PDNS 3.x that existed in PDNS < 2.9.2.5. Whereby if we have a domain in the database backend with records, if a query is unable to resolve a subdomain it would then query the recursor setup in the pdns.conf file. We have found that on Centos 6.x the rpm packages are the latest verison of pdns where by 5.x available was pdns-2.9.22-4.el5. The pdns-2.9.22-4.el5 package works as expected but when upgrading servers to Centos 6.x we loose this required functionality. pdns-backend-mysql-2.9.22-4.el5.rpm fails to install on Centos 6.x due to mysql libs that aren't availble, this is caused by an upgrade in the mysql version whereby the pdns backend mysql requires older mysql libs then what is available on centos 6.x . Installing from source is also troublesome with the following errors - http://pastebin.com/B5cUuD08

  • DENY select on sys.dm_db_index_physical_stats

    - by steveh99999
    Technorati Tags: security,DMV,permission,sys.dm_db_index_physical_stats I recently saw an interesting blog article by Paul Randal about the performance overhead of querying the sys.dm_db_index_physical_stats. So I was thinking, would it be possible to let non-sysadmin users query DMVs on a SQL server but stop them querying this I/O intensive DMV ? Yes it is, here’s how… 1. Create a new login for test purposes, with permissions to access AdventureWorks database only … CREATE LOGIN [test] WITH PASSWORD='xxxx', DEFAULT_DATABASE=[AdventureWorks] GO USE [AdventureWorks] GO CREATE USER [test] FOR LOGIN [test] WITH DEFAULT_SCHEMA=[dbo] GO 2.login as user test and issue command SELECT  * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks'),NULL,NULL,NULL,'DETAILED') gets error :-  Msg 297, Level 16, State 12, Line 1 The user does not have permission to perform this action. 3.As a sysadmin, issue command :- USE AdventureWorks GRANT VIEW DATABASE STATE TO [test] or GRANT VIEW SERVER STATE TO [test] if all databases can be queried via DMV. 4.
