• Building a workstation computer for Image processing? [closed]

  - by echolab

  I am taking a gigapixel image my goal is 50gigapixel and shooting is almost done , i am doing some research to build a workstation so i can stitch images together , my questions is ! Could u suggest some dual cpu mainboard that works fine with xeon 5500+ , with 64GB+ ram support ? My other question is which hardware is most important in image processing , all i see in story of gigapixel panoramas is they have dual xeon and 32gb+ ram ? i wonder if i am doing this right , i mean they don't post information on graphic card , mainboard and stuff ! I did asked several websites , but nothing best answer was get some high-end workstation and plenty of hours , i don't want to purchase ready to use workstations, i wanna build it up Thanks in advance

• Introducing SSIS Reporting Pack for SQL Server code-named Denali

  - by jamiet

  In recent blog posts I have introduced the new SSIS Catalog that is forthcoming in SQL Server Code-named Denali: What's new in SSIS in Denali Introduction to SSIS Projects in Denali Parameters in SSIS In Denali SSIS Server, Catalogs, Environments and Environment Variables in SSIS in Denali The SSIS Catalog is responsible for executing SSIS packages and also for capturing the metadata from those executions. However, at the time of writing there is no mechanism provided to view analyse and drill into that metadata and that is the reason that I am, in this blog post, introducing a suite of SSIS Catalog reports called the SSIS Reporting Pack which you can download from my SkyDrive at http://cid-550f681dad532637.office.live.com/self.aspx/Public/SSIS%20Reporting%20Pack/SSISReportingPack%20v0.1.zip. In this first release the SSIS Reporting Pack includes five reports: Catalog – A high-level summary of all activity in the Catalog Folders – A summary of activity in each Catalog Folder Folder – Project-level activity per single Folder Executions – A visualisation of all executions per Folder/Project/Package/Environment or subset thereof Execution – Information about an individual execution Here is a screenshot of the Executions report: Notice that the SSIS Reporting Pack provides a visual overview of all executions in the Catalog. Each execution is represented as a bar on the bar chart, the success or otherwise of each execution is indicated by the colour of the bar and the execution time is indicated by the bar height. I have recorded a video that gives an overview of the SSIS Reporting which I have embedded below. If you are having any trouble viewing the video go see it at http://vimeo.com/17617974 I must stress that this is a very early version of the SSIS Reporting Pack and I am expecting it to change a lot over the coming year. I am very keen to get some feedback about this, specifically: let me know if anything does not work as you expect give me your feature requests The easiest way to get hold of of me for now is within the comments section of this blog post. That’s all for now. I hope the SSIS Reporting Pack proves useful and I look forward to hearing your feedback. Lastly, that download link again: http://cid-550f681dad532637.office.live.com/self.aspx/Public/SSIS%20Reporting%20Pack/SSISReportingPack%20v0.1.zip. @jamiet

• Partition Wise Joins

  - by jean-pierre.dijcks

  Some say they are the holy grail of parallel computing and PWJ is the basis for a shared nothing system and the only join method that is available on a shared nothing system (yes this is oversimplified!). The magic in Oracle is of course that is one of many ways to join data. And yes, this is the old flexibility vs. simplicity discussion all over, so I won't go there... the point is that what you must do in a shared nothing system, you can do in Oracle with the same speed and methods. The Theory A partition wise join is a join between (for simplicity) two tables that are partitioned on the same column with the same partitioning scheme. In shared nothing this is effectively hard partitioning locating data on a specific node / storage combo. In Oracle is is logical partitioning. If you now join the two tables on that partitioned column you can break up the join in smaller joins exactly along the partitions in the data. Since they are partitioned (grouped) into the same buckets, all values required to do the join live in the equivalent bucket on either sides. No need to talk to anyone else, no need to redistribute data to anyone else... in short, the optimal join method for parallel processing of two large data sets. PWJ's in Oracle Since we do not hard partition the data across nodes in Oracle we use the Partitioning option to the database to create the buckets, then set the Degree of Parallelism (or run Auto DOP - see here) and get our PWJs. The main questions always asked are: How many partitions should I create? What should my DOP be? In a shared nothing system the answer is of course, as many partitions as there are nodes which will be your DOP. In Oracle we do want you to look at the workload and concurrency, and once you know that to understand the following rules of thumb. Within Oracle we have more ways of joining of data, so it is important to understand some of the PWJ ideas and what it means if you have an uneven distribution across processes. Assume we have a simple scenario where we partition the data on a hash key resulting in 4 hash partitions (H1 -H4). We have 2 parallel processes that have been tasked with reading these partitions (P1 - P2). The work is evenly divided assuming the partitions are the same size and we can scan this in time t1 as shown below. Now assume that we have changed the system and have a 5th partition but still have our 2 workers P1 and P2. The time it takes is actually 50% more assuming the 5th partition has the same size as the original H1 - H4 partitions. In other words to scan these 5 partitions, the time t2 it takes is not 1/5th more expensive, it is a lot more expensive and some other join plans may now start to look exciting to the optimizer. Just to post the disclaimer, it is not as simple as I state it here, but you get the idea on how much more expensive this plan may now look... Based on this little example there are a few rules of thumb to follow to get the partition wise joins. First, choose a DOP that is a factor of two (2). So always choose something like 2, 4, 8, 16, 32 and so on... Second, choose a number of partitions that is larger or equal to 2* DOP. Third, make sure the number of partitions is divisible through 2 without orphans. This is also known as an even number... Fourth, choose a stable partition count strategy, which is typically hash, which can be a sub partitioning strategy rather than the main strategy (range - hash is a popular one). Fifth, make sure you do this on the join key between the two large tables you want to join (and this should be the obvious one...). Translating this into an example: DOP = 8 (determined based on concurrency or by using Auto DOP with a cap due to concurrency) says that the number of partitions >= 16. Number of hash (sub) partitions = 32, which gives each process four partitions to work on. This number is somewhat arbitrary and depends on your data and system. In this case my main reasoning is that if you get more room on the box you can easily move the DOP for the query to 16 without repartitioning... and of course it makes for no leftovers on the table... And yes, we recommend up-to-date statistics. And before you start complaining, do read this post on a cool way to do stats in 11.

• Mission 26 Captures Endeavour’s Last Trip in Stop Motion

  - by Jason Fitzpatrick

  On September 21, 2012 the Space Shuttle Endeavour was delivered to the Los Angeles International Airport and spent the next three days being slowly transported 12 miles to the California Science Center. One dedicated team of photographers captured the whole thing. Lead by Matthew Givot, the group followed the shuttle for three straight days, photographing it around the clock. The Endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town. No matter how many times I would see the Shuttle it would never get old. This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy. The end result of their labor is the above video, a beautiful time-lapse video of Endeavour’s journey from the airport to its hanger at the California Science Center.

  A few days ago, I have asked a question on this blog. The question was - What would you like to see in the next episodes of SQL in Sixty Seconds. The poll is still active and posted over here: SQL SERVER – Poll – What would you love to see in SQL in Sixty Seconds? The contest was to suggest the next item of SQL in Sixty Seconds and vote for the your choice of subject. There have been plenty of votes to this contest, however, there were only 4 comments to this blog post. Hence, selecting a winner was very simple. Result of Poll It is very clear from result, most of the people would like to watch Performance Tuning subjects. I will continue to build video on this subject in future. Contest Winner Now is the time for the winner of the contest, who left comments on the blog. The winner is Raelyard. Here is the comment which he has left on the blog. raelyard please reach out to me via email and I will send you the gift card.

• SQL SERVER – Cardinality Estimation and Performance – SQL in Sixty Seconds #072

  - by Pinal Dave

  Yesterday I wrote blog post based on my latest Pluralsight course on learning SQL Server 2014. I discussed newly introduced cardinality estimation in SQL Server 2014 and how it improves the performance of the query. The cardinality estimation logic is responsible for quality of query plans and majorly responsible for improving performance for any query. This logic was not updated for quite a while, but in the latest version of SQL Server 2104 this logic is re-designed. The new logic now incorporates various assumptions and algorithms of OLTP and warehousing workload. I hope my earlier blog post clearly explained how new cardinality estimation logic improves performance. If not, I suggest you watch following quick video where I explain this concept in extremely simple words. You can download the code used in this course from Simple Demo of New Cardinality Estimation Features of SQL Server 2014. Action Item Here are the blog posts I have previously written. You can read it over here: Simple Demo of New Cardinality Estimation Features of SQL Server 2014 Pluralsight Course You can subscribe to my YouTube Channel for frequent updates.

• Why are my videos playing speeded up with no audio, but work fine if I log in as a guest?

  - by Martins Kruze

  Since the start of this week I have been experiencing a glitch in the multimedia on my Samsung R518 laptop. I have 2 problems: Videos in every player are speeded up around 2 or 4 times (including youtube.com (both HTML5 and flash variants), any other video on the web and videos on my laptop played by Totem Media Player), exception is VLC player, but 2nd problem does concern even that. There is no sound - simple as that (with or without headphones plugged in). These all problems are now, and has not seen before, I upgraded to Ubuntu 10.10 after it was possible, and from start I didn't have anything from this - it just started in this week. I haven't even putted new software in. I have more or less solved the question (kind of) - I just logged in as a guest - and it all works, but when I make a new user - it does not. Please help me.

• Display Problems running Ubuntu 12.04 in Windows VMware Player

  - by Alex Reynolds

  I am posting this again because I have changed to VMWare Player and I discovered something new. I am running Ubuntu 12.04 LTS (Guest) in VMWare Player 6.0.2 on Windows 7 64-bit Host. I have VMWare Tools installed properly. I am running MATE but the problem persists when I change (to and from) xfce, gnome, mate a-- and back again I had been using this for a couple of years without any graphics issues. After an Ubuntu update (typical) -- my video is corrupt and will not refresh correctly. My desktop icons are "mirrored" and when I open a terminal window (for instance) -- sometimes -- the window appears multiple times. Of course, only one is the real image. It seems to be a refresh problem. When I move an active window around the screen the "older" images "erase" and my icons (for instance) are in the correct location. For instance, I can move the terminal around a pretty corrupted window and the screen behind it is repainted correctly. NEW: Next, I got the idea to try and Remote Desktop in to the Ubuntu 12.04 LTS Guest OS from my Windows 7 64-bit Host. Once working, and connected via Win RDC -- using MATE as default in my /etc/xrdp/startws.sh -- my video is not corrupted and works fine (as in the past). Any ideas about what is going on ? or how to fix this ?

• Can't log in to GNOME after upgrade (raring -> saucy)

  - by x-yuri

  I've just upgraded my ubuntu (raring to saucy) and I now can't log in to GNOME. As opposed to virtual consoles (Ctrl-Alt-F1, for example). I set it up to log in automatically. But it asks for password now. I type in the password, press Enter, the screen blinks and here I am again at the login screen.

• How can fix HDMI HDTV overscan when I my TV has no aspect ratio setting?

  - by Colin Dean

  I have a 32" Vizio HDTV. It's a few years old, but running well. I just connected a new nettop to it using HDMI out. It's the Intel 3x00 graphics chipset. I'm seeing overscan, where the resolution in Ubuntu is set to 1280x720, but the TV itself is 1366x768. When I go into the Monitors control applet, I cannot change the resolution to anything other than the current or 640x480. A user had a similar overscan problem, but fixed the overscan by adjusting his TV's aspect ratio settings. I do not have that luxury. Is there a way I can do this without having to delve into xorg.conf or other command-line craziness? I'm more than comfortable doing so, but there must be a cleaner way. I'm running Ubuntu Natty, keeping up with updates and such.

• SQL SERVER – SQL in Sixty Seconds – 5 Videos from Joes 2 Pros Series – SQL Exam Prep Series 70-433

  - by pinaldave

  Joes 2 Pros SQL Server Learning series is indeed fun. Joes 2 Pros series is written for beginners and who wants to build expertise for SQL Server programming and development from fundamental. In the beginning of the series author Rick Morelan is not shy to explain the simplest concept of how to open SQL Server Management Studio. Honestly the book starts with that much basic but as it progresses further Rick discussing about various advanced concepts from query tuning to Core Architecture. This five part series is written with keeping SQL Server Exam 70-433. Instead of just focusing on what will be there in exam, this series is focusing on learning the important concepts thoroughly. This book no way take short cut to explain any concepts and at times, will go beyond the topic at length. The best part is that all the books has many companion videos explaining the concepts and videos. Every Wednesday I like to post a video which explains something in quick few seconds. Today we will go over five videos which I posted in my earlier posts related to Joes 2 Pros series. Introduction to XML Data Type Methods – SQL in Sixty Seconds #015 The XML data type was first introduced with SQL Server 2005. This data type continues with SQL Server 2008 where expanded XML features are available, most notably is the power of the XQuery language to analyze and query the values contained in your XML instance. There are five XML data type methods available in SQL Server 2008: query() – Used to extract XML fragments from an XML data type. value() – Used to extract a single value from an XML document. exist() – Used to determine if a specified node exists. Returns 1 if yes and 0 if no. modify() – Updates XML data in an XML data type. node() – Shreds XML data into multiple rows (not covered in this blog post). [Detailed Blog Post] | [Quiz with Answer] Introduction to SQL Error Actions – SQL in Sixty Seconds #014 Most people believe that when SQL Server encounters an error severity level 11 or higher the remaining SQL statements will not get executed. In addition, people also believe that if any error severity level of 11 or higher is hit inside an explicit transaction, then the whole statement will fail as a unit. While both of these beliefs are true 99% of the time, they are not true in all cases. It is these outlying cases that frequently cause unexpected results in your SQL code. To understand how to achieve consistent results you need to know the four ways SQL Error Actions can react to error severity levels 11-16: Statement Termination – The statement with the procedure fails but the code keeps on running to the next statement. Transactions are not affected. Scope Abortion – The current procedure, function or batch is aborted and the next calling scope keeps running. That is, if Stored Procedure A calls B and C, and B fails, then nothing in B runs but A continues to call C. @@Error is set but the procedure does not have a return value. Batch Termination – The entire client call is terminated. XACT_ABORT – (ON = The entire client call is terminated.) or (OFF = SQL Server will choose how to handle all errors.) [Detailed Blog Post] | [Quiz with Answer] Introduction to Basics of a Query Hint – SQL in Sixty Seconds #013 Query hints specify that the indicated hints should be used throughout the query. Query hints affect all operators in the statement and are implemented using the OPTION clause. Cautionary Note: Because the SQL Server Query Optimizer typically selects the best execution plan for a query, it is highly recommended that hints be used as a last resort for experienced developers and database administrators to achieve the desired results. [Detailed Blog Post] | [Quiz with Answer] Introduction to Hierarchical Query – SQL in Sixty Seconds #012 A CTE can be thought of as a temporary result set and are similar to a derived table in that it is not stored as an object and lasts only for the duration of the query. A CTE is generally considered to be more readable than a derived table and does not require the extra effort of declaring a Temp Table while providing the same benefits to the user. However; a CTE is more powerful than a derived table as it can also be self-referencing, or even referenced multiple times in the same query. A recursive CTE requires four elements in order to work properly: Anchor query (runs once and the results ‘seed’ the Recursive query) Recursive query (runs multiple times and is the criteria for the remaining results) UNION ALL statement to bind the Anchor and Recursive queries together. INNER JOIN statement to bind the Recursive query to the results of the CTE. [Detailed Blog Post] | [Quiz with Answer] Introduction to SQL Server Security – SQL in Sixty Seconds #011 Let’s get some basic definitions down first. Take the workplace example where “Tom” needs “Read” access to the “Financial Folder”. What are the Securable, Principal, and Permissions from that last sentence? A Securable is a resource that someone might want to access (like the Financial Folder). A Principal is anything that might want to gain access to the securable (like Tom). A Permission is the level of access a principal has to a securable (like Read). [Detailed Blog Post] | [Quiz with Answer] Please leave a comment explain which one was your favorite video as that will help me understand what works and what needs improvement.

• SQL Server connection string Asynchronous Processing=true

  - by George2

  Hello everyone, I am using .Net 2.0 + SQL Server 2005 Enterprise + VSTS 2008 + C# + ADO.Net to develop ASP.Net Web application. My question is, if I am using Asynchronous Processing=true with SQL Server authentication mode (not Windows authentication mode, i.e. using sa account and password in connection string in web.config), I am wondering whether Asynchronous Processing=true will impact performance of my web application (or depends on my ADO.Net code implementation pattern/scenario)? And why? thanks in advance, George

• WPF Animation / Processing priority

  - by Matt B

  Hi all, I have a button which has an animation (in xaml) on it's click event. Cool so far. Problem is that I also have processing occurring on the click event (so I can do stuff) - and this occurs first. How do I prioritise or re-order so that the animation takes place before any custom processing... Thanks.

• jGrowl with asp.net server side processing

  - by Mike

  Hi, Is it possible to create a new thread in asp.net to do some processing, and then upon completion, set a flag so that when the user requests the next page, I can insert some extra text or code to perform some notification? Or if it is possible to send some text to the browser after the request has completed? For example jGrowl would be great to have a notification after some processing has been performed. Thanks

• Rails 3 Processing by */*

  - by Maestro

  I have noticed that in Rails 3.2.2, all actions are being processed with */* format. So the question is: what means */* ? And why it is called by default (every time) ? Because there are two processings for one action: Started GET "/" for 127.0.0.1 at 2012-07-07 22:50:22 +0200 Processing by MainController#index as HTML Started GET "/" for 127.0.0.1 at 2012-07-07 22:50:22 +0200 Processing by MainController#index as */* I have tried to set: respond_to :html def index @posts = Post.all respond_with(@posts) end But the same problem still exists.

• Signal processing or algorithmic programming for a PLC

  - by james singen smythe

  I have an application that takes voltages and temperatures as analog inputs and does some processing using an algorithm which involves signal processing such as low-pass filtering, exponential smoothing, and other steps which might typically be done in a high-level programming language such as C or C++. I'm curious how I could perform these same steps using a PLC, and in particular, the Allen-Bradley Control-Logix system? It seems to me that the instruction set with ladder logic is too limited for this. Could I perform this using structured text?

• Dynamically refresh JTextArea as processing occurs?

  - by digiarnie

  I am trying to create a very simple Swing UI that logs information onto the screen via a JTextArea as processing occurs in the background. When the user clicks a button, I want each call to: textArea.append(someString + "\n"); to immediately show up in the UI. At the moment, the JTextArea does not show all log information until the processing has completed after clicking the button. How can I get it to refresh dynamically?

• Pumpktris: The Tetris-Enabled Jack-o’-Lantern [Video]

  - by Jason Fitzpatrick

  You can carve a pumpkin, you might even go high-tech and wire it up with a few LEDs, but can you play Tetris on it? Check out this fully functional Tetris clone built into a jack-o’-lantern. The build comes to us courtesy of tinker Nathan at HaHaBird, who writes: One of my habits is to write down all the crazy, fleeting ideas I have, then go back to review later rather than judging right off the bat, or even worse, forgetting them. Earlier in the month I was looking through that idea notepad and found “Make Tetris Pumpkins” from sometime last year. My original plan had been to make forms to shape pumpkins into Tetris pieces as they grew, then stack them together for Halloween. Since Halloween was only a few weeks away and it was too late to start growing pumpkins, I thought “Why not make a pumpkin you can play Tetris on instead?” Watch the Pumpktris in action via the video above or hit up the link below to see exactly how he went about building it.

• SQLAuthority News – Guest Post – FAULT Contract in WCF with Learning Video

  - by pinaldave

  This is guest post by one of my very good friends and .NET MVP, Dhananjay Kumar. The very first impression one gets when they meet him is his politeness. He is an extremely nice person, but has superlative knowledge in .NET and is truly helpful to all of us. Objective: This article will give a basic introduction on: How to handle Exception at service side? How to use Fault contract at Service side? How to handle Service Exception at client side? A Few Points about Exception at Service Exception is technology-specific. Exception should not be shared beyond service boundary. Since Exception is technology-specific, it cannot be propagated to other clients. Exception is of many types. CLR Exception Windows32 Exception Runtime Exception at service C++ Exception Exception is very much native to the technology in which service is made. Exception must be converted from technology-specific information to natural information that can be communicated to the client. SOAP Fault FaultException<T> Service should throw FaultException<T>, instead of the usual CLR exception. FaultException<T> is a specialization of Fault Exception. Any client that programs against FaultException can handle the Exception thrown by FaultException<T>. The type parameter T conveys the error detail. T can be of any type like Exception, CLR Type or any type that can be serialized. T can be of type Data contract. T is a generic parameter that conveys the error details.
