• July, the 31 Days of SQL Server DMO’s – Day 28 (sys.dm_db_stats_properties)

  - by Tamarick Hill

  The sys.dm_db_stats_properties Dynamic Management Function returns information about the statistics that are currently on your database objects. This function takes two parameters, an object_id and a stats_id. Let’s have a look at the result set from this function against the AdventureWorks2012.Sales.SalesOrderHeader table. To obtain the object_id and stats_id I will use a CROSS APPLY with the sys.stats system table. SELECT sp.* FROM sys.stats s CROSS APPLY sys.dm_db_stats_properties(s.object_id, s.Stats_id) sp WHERE sp.object_id = object_id('Sales.SalesOrderHeader') The first two columns returned by this function are the object_id and the stats_id columns. The next column, ‘last_updated’, gives you the date and the time that a particular statistic was last updated. The next column, ‘rows’, gives you the total number of rows in the table as of the last statistic update date. The ‘rows_sampled’ column gives you the number of rows that were sampled to create the statistic. The ‘steps’ column represents the number of specific value ranges from the statistic histogram. The ‘unfiltered_rows’ column represents the number of rows before any filters are applied. If a particular statistic is not filtered, the ‘unfiltered_rows’ column will always equal the ‘rows’ column. Lastly we have the ‘modification_counter’ column which represents the number of modification to the leading column in a given statistic since the last time the statistic was updated. Probably the most important column from this Dynamic Management Function is the ‘last_updated’ column. You want to always ensure that you have accurate and updated statistics on your database objects. Accurate statistics are vital for the query optimizer to generate efficient and reliable query execution plans. Without accurate and updated statistics, the performance of your SQL Server would likely suffer.

• Browser-based GUI for a python application

  - by ack__

  I want to create a web/browser-based GUI for a command-line python application. The goal is to make use of HTML/JS technologies to create this GUI. As the application itself, it needs to run on Linux and Windows, and the interface will be accessible only from localhost (not exposed to internet). The GUI will contain 5 to 10 pages. I don't want a traditional desktop GUI that includes HTML/JS, but just a bunch of html files and some kind of controller between those and the application. I also want to make use of asynchronous programming (ajax like) so I can load and print data in the GUI without refreshing the whole page. I'd probably use jQuery for that and a couple other things. How would you recommend to design this? Performance is not the key here, I'm rather looking at reliability, portability and simplicity. I'm thinking of using a lightweight python HTTP server / framework (like CherryPy) and maybe later a Python templating system (at the begining it will just be a couple pages). EDIT: I'm looking for ideas/recommendations how to build this, not for alternatives to browser/web-based GUI.

• Why is Quicksort called "Quicksort"?

  - by Darrel Hoffman

  The point of this question is not to debate the merits of this over any other sorting algorithm - certainly there are many other questions that do this. This question is about the name. Why is Quicksort called "Quicksort"? Sure, it's "quick", most of the time, but not always. The possibility of degenerating to O(N^2) is well known. There are various modifications to Quicksort that mitigate this problem, but the ones which bring the worst case down to a guaranteed O(n log n) aren't generally called Quicksort anymore. (e.g. Introsort). I just wonder why of all the well-known sorting algorithms, this is the only one deserving of the name "quick", which describes not how the algorithm works, but how fast it (usually) is. Mergesort is called that because it merges the data. Heapsort is called that because it uses a heap. Introsort gets its name from "Introspective", since it monitors its own performance to decide when to switch from Quicksort to Heapsort. Similarly for all the slower ones - Bubblesort, Insertion sort, Selection sort, etc. They're all named for how they work. The only other exception I can think of is "Bogosort", which is really just a joke that nobody ever actually uses in practice. Why isn't Quicksort called something more descriptive, like "Partition sort" or "Pivot sort", which describe what it actually does? It's not even a case of "got here first". Mergesort was developed 15 years before Quicksort. (1945 and 1960 respectively according to Wikipedia) I guess this is really more of a history question than a programming one. I'm just curious how it got the name - was it just good marketing?

• Current Technologies

  - by Charles Cline

  I currently work at the University of Kansas (KU) and before that Stanford University, to be particular the Stanford Linear Accelerator Center (SLAC).  Collaborating with various Higher Ed institutions the past several years has shown a marked increase in the Microsoft side of the house.  To give you an idea of our current environment, here are some of the things we (Enterprise Systems) have been working on the past two years I’ve been at KU: Migrated from Novell to Active Directory (AD), although we’re still leveraging Novell for IDM.  We currently have 550,000+ objects in AD, and we still have several departments to bring in. Upgraded from Exchange 2003 to Exchange 2010 and Forefront Online Protection for Exchange (FOPE) Implemented SCCM 2007 for Windows systems management Implemented central file storage using EMC products for the backend, using CIFS as the frontend Restructuring AD domains and Forests to decrease the administrative overhead and provide a primary authentication mechanism for the entire University Determining Key Performance Indicators for AD and Exchange Implemented SCOM 2007 to monitor AD and Exchange Implemented Confluence for collaboration within IT and other technology providers at the University Implemented Data Protection Manager (DPM) for backup of AD and Exchange Built a test and QA environment to better facilitate upcoming changes to the environment Almost ready to raise the AD domain level to 2008 R2   I’m sure I’m missing things, and my next post will be some of the things we’re getting ready for – like Centrify to provide AD for OS X and Linux systems.  If anyone would like more info on a particular area, please drop me a line.  I’d be happy to discuss.

• White Paper on Analysis Services Tabular Large-scale Solution #ssas #tabular

  - by Marco Russo (SQLBI)

  Since the first beta of Analysis Services 2012, I worked with many companies designing and implementing solutions based on Analysis Services Tabular. I am glad that Microsoft published a white paper about a case-study using one of these scenarios: An Analysis Services Case Study: Using Tabular Models in a Large-scale Commercial Solution. Alberto Ferrari is the author of the white paper and many people contributed to it. The final result is a very technical document based on a case study, which provides a level of detail that I don’t see often in other case studies (which are usually more marketing-oriented). This white paper has the following structure: Requirements (data model, capacity planning, client tool) Options considered (SQL Server Columnstore Indexes, SSAS Multidimensional, SSAS Tabular) Data Model optimizations (memory compression, query performance, scalability) Partitioning and Processing strategy for near real-time latency Hardware selection (NUMA analysis, Azure VM tests) Scalability tests (estimation of maximum users per node) If you are in charge of evaluating Tabular as analytical engine, or if you have to design your solution based on Tabular, this white paper is a must read. But if you just want to increase your knowledge of Analysis Services, you will find a lot of useful technical information. That said, my favorite quote of the document is the following one, funny but true: […] After several trials, the clear winner was a video gaming machine that one guy on the team used at home. That computer outperformed any available server, running twice as fast as the server-class machines we had in house. At that point, it was clear that the criteria for choosing the server would have to be expanded a bit, simply because it would have been impossible to convince the boss to build a cluster of gaming machines and trust it to serve our customers.  But, honestly, if a business has the flexibility to buy gaming machines (assuming the machines can handle capacity) – do this. Owen Graupman, inContact I want to write a longer discussion about how companies are adopting Tabular in scenarios where it is the hidden engine of a more complex solution (and not the classical “BI system”), because it is more frequent than you might expect (and has several advantages over many alternative approaches).

• CERN Announces the Discovery of a Higgs-Boson-like Particle

  - by Jason Fitzpatrick

  CERN scientists dropped a press release today indicating they’ve found a particle consistent with the long sought after Higgs Boson particle–the “God” particle, that could help radically refine our understanding of Standard Model of Particle Physics. For years scientists at CERN have been harnessing the power of the Large Hadron Collider to answer fundamental questions about the nature of particles and the universe around us. In the above video John Ellis, a theoretical physicist, answers the question “What is the Higgs Boson?” The video pairs nicely with the CERN press release: “We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.” “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.” “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.” How to Use an Xbox 360 Controller On Your Windows PC Download the Official How-To Geek Trivia App for Windows 8 How to Banish Duplicate Photos with VisiPic

  - by David Butler

  Oracle is sponsoring the Product MDM track at this year’s MDM & Data Governance San Francisco Summit. Sachin Patel, Director of Product Strategy, Product Hub Applications, at Oracle will present the keynote: Product Master Data Management for Today’s Enterprise. Here’s the abstract: Today businesses struggle to boost operational efficiency and meet new product launch deadlines due to poor and cumbersome administrative processes. One of the primary reasons enterprises are unable to achieve cohesion is due to various domain silos and fragmented product data. This adversely affects business performance including, but not limited to, excess inventories, under-leveraged procurement spend, downstream invoicing or order errors and lost sales opportunities. In this session, you will learn the key elements and business processes that are required for you to master an enterprise product record. Additionally you will gain insights into how to improve the accuracy of your data and deliver reliable and consistent product information across your enterprise. This provides a high level of confidence that business managers can achieve their goals. In this session, you will understand how adopting a Master Data Management strategy for product information can help your enterprise change course towards a more profitable, competitive and successful business. Cisco Systems will join Sachin and cover their experiences, lessons learned and best practices. If you are in the Bay Area and interested in mastering your product data for the benefit of multiple applications, business processes and analytical systems, please join us at the Hyatt, Fisherman’s Wharf this Thursday, June 30th.

• Output = MAXDOP 1

  - by Dave Ballantyne

  It is widely know that data modifications on table variables do not support parallelism, Peter Larsson has a good example of that here .  Whilst tracking down a performance issue,  I saw that using the OUTPUT clause also causes parallelism to not be used. By way of example,  first lets create two tables with a simple parent and child (one to one) relationship, and then populate them with 100,000 rows. Drop table ParentDrop table Childgocreate table Parent(id integer identity Primary Key,data1 char(255))Create Table Child(id integer Primary Key)goinsert into Parent(data1)Select top 1000000 NULL from sys.columns a cross join sys.columns b insert into ChildSelect id from Parentgo If we then execute update Parent set data1 =''from Parentjoin Child on Parent.Id = Child.Id where Parent.Id %100 =1 and Child.id %100 =1 We should see an execution plan using parallelism such as   However,  if the OUTPUT clause is now used update Parent set data1 =''output inserted.idfrom Parentjoin Child on Parent.Id = Child.Id where Parent.Id %100 =1 and Child.id %100 =1   The execution plan shows that Parallelism was not used Make of that what you will, but i thought that this was a pretty unexpected outcome. Update : Laurence Hoff has mailed me to note that when the OUTPUT results are captured to a temporary table using the INTO clause,  then parallelism is used.  Naturally if you use a table variable then there is still no parallelism

• Wifi range issues and intermittent dropouts, Thinkpad Edge

  If I am more than a couple of metres from my access point (and I'm seeing this across various APs) with my newish Thinkpad Edge 15, running 10.10, the wifi performance becomes ... flaky. When this is happening, I see the following in dmesg, although I'm not sure if it's related: [ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2502.012711] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2507.009254] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2512.008367] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2517.007467] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2522.006558] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2527.008157] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2532.007251] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2537.003838] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2542.005427] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2547.004496] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2552.003611] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded lspci -vvv has the following to say about my wireless adapter: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at f0500000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn If I get within a couple of metres of the access point, I still see that output in dmesg, but the connection stabilises. My question is threefold: how do I get better wifi range, what can/should I do about those messages in dmesg, and most crucially, are the two related? As ever let me know if there's other information that would help! Edit: I am using this machine in exactly the same locations I used my previous Thinkpad (T61) running various older versions of Ubuntu, so I definitely feel there is something wrong, rather me having unreasonable expectations of range!

• Computing pixel's screen position in a vertex shader: right or wrong?

  - by cubrman

  I am building a deferred rendering engine and I have a question. The article I took the sample code from suggested computing screen position of the pixel as follows: VertexShaderFunction() { ... output.Position = mul(worldViewProj, input.Position); output.ScreenPosition = output.Position; } PixelShaderFunction() { input.ScreenPosition.xy /= input.ScreenPosition.w; float2 TexCoord = 0.5f * (float2(input.ScreenPosition.x,-input.ScreenPosition.y) + 1); ... } The question is what if I compute the position in the vertex shader (which should optimize the performance as VSF is launched significantly less number of times than PSF) would I get the per-vertex lighting insted. Here is how I want to do this: VertexShaderFunction() { ... output.Position = mul(worldViewProj, input.Position); output.ScreenPosition.xy = output.Position / output.Position.w; } PixelShaderFunction() { float2 TexCoord = 0.5f * (float2(input.ScreenPosition.x,-input.ScreenPosition.y) + 1); ... } What exactly happens with the data I pass from VS to PS? How exactly is it interpolated? Will it give me the right per-pixel result in this case? I tried launching the game both ways and saw no visual difference. Is my assumption right? Thanks. P.S. I am optimizing the point light shader, so I actually pass a sphere geometry into the VS.

• Planning for the Recovery

  - by john.orourke(at)oracle.com

  As we plan for 2011, there are many positive signs in the global economy, but also some lingering issues. Planning no longer is about extrapolating past performance and adjusting for growth. It is now about constantly testing the temperature of the water, formulating scenarios, assessing risk and assigning probabilities.  So how does one plan for recovery and improve forecast accuracy in such a volatile environment?  Here are some suggestions from a recent article I wrote, which was published in the December Financial Planning & Analysis (FP&A) newsletter from the AFP (Association of Financial Professionals): Increase the frequency of forecasting Get more line managers involved in the planning and forecasting process Re-consider what's being measured - i.e. key financial and operational metrics Incorporate risk and probability into forecasts Reduce reliance on spreadsheets - leverage packaged EPM applications To learn more about these best practices, check out the FP&A section of the AFP website and register to receive the FP&A newsletter.  AFP recently launched a new topic area focused on the FP&A function and items of interest to this group of finance professionals.  In addition to the FP&A quarterly newsletter, AFP will be publishing articles, running webinars and will have an FP&A track in their annual conference, which is in Boston next November.  Brian Kalish, AFP's Finance Lead, is hoping this initiative creates a valuable networking and information-sharing resource for FP&A professionals. Here's a link to the FP&A page on the AFP web site:  http://www.afponline.org/pub/res/topics/topics_fpa.html If you register on the site you can access and subscribe to the FP&A newsletter and other resources. Best of luck in your planning for 2011 and beyond!

• VirtualBox 3.2 Release

  - by [email protected]

  The latest version of VirtualBox is out - version 3.2.  It is the first release as Oracle VirtualBox and there are a lot of new features.  Many of these I see directly impacting the Oracle VDI solution in upcoming releases (just my guess, of course), and I am updating my notebook as I write this. Er... OK - Done!There are enough features that they warrant you taking a look at this two-page VirtualBox Community Bulletin.pdf.  No point in me restating them.If you and your organization haven't tried VirtualBox, or you haven't looked at it in a while, you owe it to yourself to give this a run.  This is small, simple, powerful, software that allows you to do way more than most people would ever need in hosting a Virtual machine on you local machine.  I routinely will do a demo on a two-year-old Macbook running OS X locally, plus a Solaris 10 VM running the Sun Ray server, and a Windows XP VM and hang a couple Sun Rays off of it - and the performance is stellar.You can subscribe to the mailing lists and get access to the Beta releases as they come out as well, if you are into 'bleeding edge'.40,000 downloads a day is the current rate (before this new release), but it will jump for sure now.  Might as well join in!

• "Are You There?".. India Tops Logistics List of Emerging Nations

  - by [email protected]

  It's just amazing how far, wide and deep modern supply chains are extending. AMR reported on 15 Apr (M.Burkett, A.Reese) in a SCM webcast that 'Penetrating Emerging Markets" was the top priotiy for organizations based on a recent survey. I took this as both adding new consumers to their prospect-list as well as leveraging 'lower cost labor arbitrage". (Read '3 Billion Capitalists") Supply Chain Quarterly reports that India and Brazil received the highest ranking of the logistics markets in developing nations India tops the list of emerging nations that scores the attractiveness of logistics markets to foreign investors. Developed by the UK-based research firm Transport Intelligence, the new  Emerging Market Logistics Index rated 38 developing countries on 3 factors. 1. "Market size and growth attractiveness," considered a country's economic output, projected growth rate, and population size.  2. "Market compatibility," which examined how well-matched a nation was with the services offered by global logistics providers. This includes a country's security levels, market accessibility, foreign direct investment, distribution of wealth and population, and development of its service sector. 3. "Connectedness," which rated the efficiency of customs and border controls, liner shipping connections, and transportation infrastructure. India claimed the top spot due to its market size and growth prospects. Brazil is second because of its economic performance, good levels of market accessibility, and improving domestic and international transport connections. Are you there?

• Collision detection on a 2D hexagonal grid

  - by SundayMonday

  I'm making a casual grid-based 2D iPhone game using Cocos2D. The grid is a "staggered" hex-like grid consisting of uniformly sized and spaced discs. It looks something like this. I've stored the grid in a 2D array. Also I have a concept of "surrounding" grid cells. Namely the six grid cells surrounding a particular cell (except those on the boundries which can have less than six). Anyways I'm testing some collision detection and it's not working out as well as I had planned. Here's how I currently do collision detection for a moving disc that's approaching the stationary group of discs: Calculate ij-coordinates of grid cell closest to moving cell using moving cell's xy-position Get list of surrounding grid cells using ij-coordinates Examine the surrounding cells. If they're all empty then no collision If we have some non-empty surrounding cells then compare the distance between the disc centers to some minimum distance required for a collision If there's a collision then place the moving disc in grid cell ij So this works but not too well. I've considered a potentially simpler brute force approach where I just compare the moving disc to all stationary discs at each step of the game loop. This is probably feasible in terms of performance since the stationary disc count is 300 max. If not then some space-partitioning data structure could be used however that feels too complex. What are some common approaches and best practices to collision detection in a game like this?

• Problem with WCF-SQL Adapter

  - by Paul Petrov

  When using WCF receive adapter with SQL binding in Polling mode please be aware of the following problem. Problem: At some regular but seemingly random intervals the application stops processing new requests, places a lock on the database and prevent other application from accessing it. Initially it looked like DTC issue, as it was distributed transaction that stalled most of the time. Symptoms: Orchestration instances in Dehydrated state, receive location not picking up new messages, exclusive locks on database tables, errors in DTC trace. Cause: Microsoft has confirmed that there is a bug in the WCF-SQL adapter. In the receive adapter binding configuration there's receiveTimeout property set to 10 minutes by default. If during this period data is not found in the table the adapter would start new thread and allocate more memory without releasing old resources. Thus if there's no new data in the table for a long time a new thread will be created in the host instance every 10 minutes until it reaches threshold (1000) and then there's no threads left for this host instance and it can't start/complete any tasks. Then this host instance won't be able to do anything. If other artifacts are hosted in the instance they will suffer consequences as well. Solution: - Set receiveTimeout to the maximum time 24.20:31:23.6470000. - Place WCF-SQL receive locations in separate host to provide its own thread pool and eliminate impact on other processes - Ensure WCF-SQL dedicated host instances are restarted at interval less or equal to receiveTimeout to flush threads and memory - Monitor performance counters Process/Thread Count/BTSNTSvc{n} for thread count trend and respond to alert if it grows by restarting host instance If you use WCF-SQL Adapter in the Notification mode then make sure to remove sqlAdapterInboundTransactionBehavior otherwise this location will exhibit the same issue. In this case though, setting receiveTimeout doesn't help and new thread will be created at default intervals (10 min) ignoring maximum setting.

• What is the best way to work with large databases in Java depending on context?

  - by Singletony

  Hi guys. We are trying to figure out the best practice for working with very large DBs in Java. What we do is a kind of BI, i.e analyzing very large DBs, and using them to create intermediate DBs that represent intelligent knowledge of the DBs. We are currently using JDBC, and just preforming queries using a ResultSet. As more and more data is being created, we are wondering whether more appropriate ways exist for parsing and manipulating these large DBs: We need to support 'chunk' manipulation and not an entire DB at once(e.g. limit in JDBC, very poor performance) We do not need to be constantly connected since we are just pulling results and creating new tables of our own. We want to understand JDBC alternatives, with respect to advantages and disadvantages. Whether you think JDBC is the way to go or not, what are the best practices to go by depending on context (e.g. for large DBs queried in chunks) ? If my question is not clear, I will gladly elaborate! THANK YOU SO MUCH!
