  • T-SQL User-Defined Functions: the good, the bad, and the ugly (part 3)

    - by Hugo Kornelis
    I showed why T-SQL scalar user-defined functions are bad for performance in two previous posts. In this post, I will show that CLR scalar user-defined functions are bad as well (though not always quite as bad as T-SQL scalar user-defined functions). I will admit that I had not really planned to cover CLR in this series. But shortly after publishing the first part , I received an email from Adam Machanic , which basically said that I should make clear that the information in that post does not apply...(read more)

  • SQLRally Nordic 2012 – session material

    - by Hugo Kornelis
    As some of you might know, I have been to SQLRally Nordic 2012 in Copenhagen earlier this week. I was able to attend many interesting sessions, I had a great time catching up with old friends and meeting new people, and I was allowed to present a session myself. I understand that the PowerPoint slides and demo code I used in my session will be made available through the SQLRally website – but I don’t know how long it will take the probably very busy volunteers to do so. And I promised my attendees...(read more)

  • SQL TuneIn Zagreb 2014 – Session material

    - by Hugo Kornelis
    I spent the last few days in Zagreb, Croatie, at the third edition of the SQL TuneIn conference , and I had a very good time here. Nice company, good sessions, and awesome audiences. I presented my “Understanding Execution Plans” precon to a small but interested audience on Monday. Participants have received a download link for the slide deck. On Tuesday I had a larger crowd for my session on cardinality estimation. The slide deck and demo code used for that presentation will be available through...(read more)

  • Is a red-black tree my ideal data structure?

    - by Hugo van der Sanden
    I have a collection of items (big rationals) that I'll be processing. In each case, processing will consist of removing the smallest item in the collection, doing some work, and then adding 0-2 new items (which will always be larger than the removed item). The collection will be initialised with one item, and work will continue until it is empty. I'm not sure what size the collection is likely to reach, but I'd expect in the range 1M-100M items. I will not need to locate any item other than the smallest. I'm currently planning to use a red-black tree, possibly tweaked to keep a pointer to the smallest item. However I've never used one before, and I'm unsure whether my pattern of use fits its characteristics well. 1) Is there a danger the pattern of deletion from the left + random insertion will affect performance, eg by requiring a significantly higher number of rotations than random deletion would? Or will delete and insert operations still be O(log n) with this pattern of use? 2) Would some other data structure give me better performance, either because of the deletion pattern or taking advantage of the fact I only ever need to find the smallest item? Update: glad I asked, the binary heap is clearly a better solution for this case, and as promised turned out to be very easy to implement. Hugo

  • What is the relation between database books by Ullman et al.?

    - by macias
    A First Course in Database Systems by Jeffrey D. Ullman, Jennifer Widom (Amazon links) Database System Implementation by Hector Garcia-Molina, Jeffrey D. Ullman, Jennifer D. Widom Database Systems: The Complete Book by Hector Garcia-Molina, Jeffrey D. Ullman, Jennifer Widom As far as I know the second one is the second "part" of the first one. But what about the third one -- is it just first+second published in one volume? I would like to buy them, but I don't want to get redundant reading. Thank you in advance for clarification.

  • USB 3.0 port with USB 3.0 device in Ubuntu 12.10

    - by fernando garcía
    When I try to connect a USB 3.0 device in Ubuntu 12.10 (ASUS K55VD, kernel 3.5.0-19-generic #30-Ubuntu SMP), the system says [ 74.747832] hub 3-0:1.0: unable to enumerate USB device on port 1 [ 74.931957] usb 4-1: new SuperSpeed USB device number 2 using xhci_hcd [ 74.949390] usb 4-1: New USB device found, idVendor=05e3, idProduct=0731 [ 74.949396] usb 4-1: New USB device strings: Mfr=0, Product=1, SerialNumber=2 [ 74.949400] usb 4-1: Product: USB Storage [ 74.949403] usb 4-1: SerialNumber: 0000000000000033 [ 75.033327] usbcore: registered new interface driver uas [ 75.038548] Initializing USB Mass Storage driver...

I have checked other questions, but either they have no answers or they told about previous Ubuntu version with 3.0.x kernels. A USB 2.0 device will work in the USB 3.0 ports. A USB 3.0 device will work (at USB 2.0 speeds) in the USB 2.0 ports. The problem, as I wrote, is between USB 3.0 devices and USB 3.0 ports. I have my USB 3.0 ports configured without legacy support via the BIOS (the way they should be, I suppose). But I also have tried to configure them with XHCI Preboot mode disabled. Have any one solved a similar problem? Thanks in advance.

  • IIS 7 (Windows Server 2008) no entrega javascript ni css

    - by José Marcos García Espinosa
    Hace algunos días, jugando con las configuraciones del IIS, revolvíamos las opciones de compresión de contenidos. La intención era habilitar gzip para el contenido estático pero la cosa salió tan mal que el portal, en vez de reducir su tamaño por los contenidos comprimidos, lo "redujo" porque el servidor dejó de enviar los archivos javascript y las hojas de estilo al navegador. Después de estar buscando como hora y media, resultó que la explicación y la solución eran bastante sencillas (y ni siquiera las encontramos nosotros): Al estar cambiando las opciones de compresión de contenidos estáticos del IIS, se crearon unos archivos de configuración (web.config's) tanto en la carpeta de los archivos javascript como en la de las hojas de estilo, que es una estructura que el propio IIS no reconocía y dejaba la aplicación 'cortada', dejando fuera estas carpetas. Eliminar ambos archivos de configuración bastó para volver a visualizar el portal como se debía.. de la compresión, creo que ya ni seguimos buscando.

  • Unable to install Win XP nor Win 7 after installing Ubuntu 11.1

    - by Pablo C. Garcia
    I'll try to make this scenario as clear as possible. Laptop Specs HP dv6-2189la: 500 HDD 4GB Ram Intel i7 Personal Specs - Linux newbie running for the first time. Quite confused :( I had Windows 7 x64, decided to start fresh new so I planned on formatting. Since I use it for work and didn't require it for another week, I didn't rush into installing Win 7 immediately as I wanted to try Ubuntu for quite a while. 1) Downloaded Ubuntu 11.1 2) Burned ISO to CD 3) Installed Ubuntu using the full HDD of 500GB erasing Win7 4) Ubuntu ran awesome (especially for me being a Linux Newbie from scratch) I used Ubuntu for a while, but now I need to get back to work with Win 7. Tried running the installation CD for Win 7 and it just skips to Ubuntu without loading. Checked BIOS, tried other discs, even tried the disc on another computer and it works. Since that didn't work, I tried running Win XP. This CD does load, it starts loading files, drives, kernel, blah blah and before even getting to install it Blue screens with error 0x0000007b. I already used Gparted and created up to 250 GB space for Windows. Formatted to NTFS. I really don´t know what do now. I've tried almost everything I know within my knowledge. I could say I'm an advanced PC user, but I bumped into the Linux wall starting from scratch. All suggestions will be appreciated. Thanks!

  • Error al instalar Visual Studio 2008 en Windows 7

    - by José Marcos García Espinosa
    Post/Install() failed in ISetupManager::InternalInstallManager() with HRESULT -2147023293. - Es el mensaje que aparece en la descripción del error o en los archivos de log. Algunos dicen que si buscas más a detalle encuentras el problema. Después de reintentar la instalación como 8 veces, desinstalando cada vez más cosas, te encuentras con que la solución es sencilla: ¡Desinstala Office! No sé por qué, pero creo que Microsoft asume que si eres un desarrollador, primero instalarás VS2008 y después Office; si lo haces al revés, se generan problemas de compatibilidad (ya que VS2008 instala herramientas de interoperabilidad/desarrollo/conexión con Office, Visual Studio Tools for Office) y la instalación no pasa a veces ni del .net Framework. A final de cuentas, creo, ésta es una medio sencilla.

    Possible Duplicate: There's an issue with an Alpha/Beta Release of Ubuntu, what should I do? Do you know when Mysql workbench would be available in ubuntu repositories.

Thanks.

  • How can I get Japanese, Chinese and Korean input to work properly on Skype, aMsn and other softwares

    - by Camilo García
    I have installed the packages for Japanese (Anthy),and those for Chinese and Korean input. They work perfectly on most of the software that come with Ubuntu, such as the LibreOffice suite and the browsers, however, I cannot input any of these three languages on Skype, aMsn or almost any software I have downloaded/installed myself. For example I have installed a Japanese-English dictionary called Tagaini Jisho, and I CANNOT input Japanese on it! I love Ubuntu, except the issues I have been experincing when I want to use these language tools. Can anybody please help me about this issue. Thank you in advance. Best regards

  • Windows doesn't boot after Ubuntu installation

    - by Diogo Garcia
    I have had serious problems installing Ubuntu and Windows and have dual boot. Recently I installed both operating systems, Ubuntu was the last one, and after that my computer was booting directly to Windows 7. I used my Ubuntu USB live to repair the grub, and could repair. Now I initiate my pc with grub 1.99 and Ubuntu and Windows are recognized, but Windows gives an error and don't initiate, suggesting to use Windows DVD to repair the grub. I tried that but with no effects on be behavior. I have a new asus n56vm. This conflicts with gpt and mbr have been a huge pain to me. I don't know what to to, I installed Ubuntu and Windows numerous times since I bought this computer 2 weeks ago.

  • How to provide value?

    - by Francisco Garcia
    Before I became a consultant all I cared about was becoming a highly skilled programmer. Now I believe that what my clients need is not a great hacker, coder, architect... or whatever. I am more and more convinced every day that there is something of greater value. Everywhere I go I discover practices where I used to roll my eyes in despair. I saw the software industry with pink glasses and laughed or cried at them depending on my mood. I was so convinced everything could be done better. Now I believe that what my clients desperately need is finding a balance between good engineering practices and desperate project execution. Although a great design can make a project cheap to maintain thought many years, usually it is more important to produce quick fast and cheap, just to see if the project can succeed. Before that, it does not really matters that much if the design is cheap to maintain, after that, it might be too late to improve things. They need people who get involved, who do some clandestine improvements into the project without their manager approval/consent/knowledge... because they are never given time for some tasks we all know are important. Not all good things can be done, some of them must come out of freewill, and some of them must be discussed in order to educate colleagues, managers, clients and ourselves. Now my big question is. What exactly are the skills and practices aside from great coding that can provide real value to the economical success of software projects? (and not the software architecture alone)
