  • Strategy for managing lots of pictures for a website

    - by Nate
    I'm starting a new website that will (hopefully) have a lot of user generated pictures. I'm trying to figure out the best way to store and serve these pictures. The CMS I'm using (umbraco) has a media library that puts a folder on the server for each image. Inside of there you can have different sizes of that same image. That folder has an ID on it and the database has additional information for that image along with the ID of the folder. This works great for small sites, but what if the pictures get up to 10,000, 100,000 or 1,000,000? It seems like the lookup on the directory would take a long time to find the correct folder. I'm on windows 2008 if that makes a difference. I'm not so worried about load. I can load balance my server pretty easily and replicate the images across the servers. The nature of the site won't have a lot of users on it either, but it could have a lot of pics. Thanks. -Nate EDIT After some thought I think I'm going to create a directory for each user under a root image folder then have user's pictures under that. I would be pretty stoked if I had even 5,000 users, so that shouldn't be too bad of a linear lookup. If it does get slow I will break it down into folders like /media/a/adam/image123.png. If it ever gets really big I will expand the above method to build a bigger tree. That would take a LOT of content though.

  • Super-silent (mid tower) case and fan combo

    - by Dennis G.
    I want to build a HTPC for music/video/blu-ray playback (no gaming). I don't need an expensive HTPC case but just want to go with a standard medium tower case. However, I want it to be super silent so it doesn't make any annoying fan/disk noises when I watch movies. Ideally, it shouldn't make any noticeable noise at all. I understand that choosing a board, CPU and graphic card that run cool and don't consume a lot of power is important for designing a quiet machine, and I think I got that covered. However, there are so many choices in regards to cases, fans and power supplies that it's hard to get started. What are your recommendations for a case/fan (cpu+case)/power supply combination that run absolutely silent and can cool a standard Intel system with a low-power (possibly passively cooled) graphic card? I'm usually a fan of Antec cases, would an Antec Mini P180 be a good starting point? If so, which case fans, CPU fan and power supply would you recommend?

  • How to talk a client out of a Flash website?

    - by bunglestink
    I have recently been doing a bunch of web side projects through word of mouth recommendations only. Although I am much more a of a programmer than a designer by any means, my design skills are not terrible, and do not hate dealing with UI like many programmers. As a result, I find myself lured into a bunch of side projects where aside from a minimal back end for content administration, most of the programming is on front end interfaces (read javascript/css). By far the biggest frustration I have had is convincing clients that they do not want Flash. Aside the fact that I really do not enjoy Flash "development", there are many practical reasons why Flash is not desirable (lack of compatibility across devices, decreased client accessibility, plug-in requirements, increased development time, etc.). Instead of just flat out telling the clients "I will not build you a flash website", I would much rather use tactics to convince/explain to them that this is not what they actually want, ie: meet their requirements any better than standard html/css/js and distract users from their content. What kind of first hand experience do others have with this? How do you explain to someone that javascript/css/AJAX is usually a better option for most websites? Why do people want to use Flash so bad to begin with? This question pertains to clients who do not have any technical reasons for wanting flash, but just want it because they think it makes pretty websites.

  • SQL Rally Pre-Con: Data Warehouse Modeling – Making the Right Choices

    - by Davide Mauri
    As you may have already learned from my old post or Adam’s or Kalen’s posts, there will be two SQL Rally in North Europe. In the Stockholm SQL Rally, with my friend Thomas Kejser, I’ll be delivering a pre-con on Data Warehouse Modeling: Data warehouses play a central role in any BI solution. It's the back end upon which everything in years to come will be created. For this reason, it must be rock solid and yet flexible at the same time. To develop such a data warehouse, you must have a clear idea of its architecture, a thorough understanding of the concepts of Measures and Dimensions, and a proven engineered way to build it so that quality and stability can go hand-in-hand with cost reduction and scalability. In this workshop, Thomas Kejser and Davide Mauri will share all the information they learned since they started working with data warehouses, giving you the guidance and tips you need to start your BI project in the best way possible?avoiding errors, making implementation effective and efficient, paving the way for a winning Agile approach, and helping you define how your team should work so that your BI solution will stand the test of time. You'll learn: Data warehouse architecture and justification Agile methodology Dimensional modeling, including Kimball vs. Inmon, SCD1/SCD2/SCD3, Junk and Degenerate Dimensions, and Huge Dimensions Best practices, naming conventions, and lessons learned Loading the data warehouse, including loading Dimensions, loading Facts (Full Load, Incremental Load, Partitioned Load) Data warehouses and Big Data (Hadoop) Unit testing Tracking historical changes and managing large sizes With all the Self-Service BI hype, Data Warehouse is become more and more central every day, since if everyone will be able to analyze data using self-service tools, it’s better for him/her to rely on correct, uniform and coherent data. Already 50 people registered from the workshop and seats are limited so don’t miss this unique opportunity to attend to this workshop that is really a unique combination of years and years of experience! http://www.sqlpass.org/sqlrally/2013/nordic/Agenda/PreconferenceSeminars.aspx See you there!

  • Kubuntu 11.04 bad experience, Gimp crashes and other bugs

    - by giowck
    I installed Kubuntu 11.04 64bit today. First let me expose some issues, this is not a rant, just some observations on Kubuntu 11.04 :) Flash doesn't work. The package "flashplugin-installer" was installed by rekonq. But still no flash. Additional Drivers (jockey-kde) doesn't show up automatically after first login. I tried to delete a large file (19,2 GB), an error appeared: "Please empty the trash first, no more space available" or something like that, but you know what? My trash was empty! (Then I found in Dolphin the settings to increment the max size of the trash). Amarok has no play/pause/forward/back buttons, only after changing settings to show those buttons on the top bar. GTK applications like ubuntu software center, inkscape... are in english, but my default language is "german". Only gimp allows to install the "de" language pack. The numblock turns off after each restart. In the KDE Control Center, the "remember last state" of numblock is set. But this is not working. I had some crashes: Nepomuk, Policy-kit, plasma-workspace and gimp. But now to the important stuff. I really need Gimp to work. After starting it, I get a crash: giowck@giowck-desktop:~$ gimp (gimp:1899): GLib-WARNING **: /build/buildd/glib2.0-2.28.6/./glib/goption.c:2132: ignoring no-arg, optional-arg or filename flags (8) on option of type 0 Speicherzugriffsfehler (in English: "Memory error") What can I do to run Gimp? Thanks

  • Would this be viewed poorly amongst the programming community?

    - by Eric P
    So one of my responsibilities at work is to build an internal tool that helps the workers enter in all their information. It's an enterprise application that is similar to a Windows forms database tool. So it's not much different than like developing a Word + Excel combo application, but the average person in this workgroup is a 20-40 year old woman or a random chatty male type. Plus I know all of these people are heavily involved with Facebook on a daily basis. How bad would it be if I styled my new interface to be similar to what Facebook does. People could get award points and stuff when they fill out different types of forms and basically compete against each other like it was a game. When people had completed one, it would be posted on their wall and everyone could comment/like stuff just like in Facebook. And it would be like they are doing peer reviewing for fun. The rewards would be outstanding I would imagine. These people are so into Facebook and Facebook games that productivity would rise due to them trying to compete and earn points and achievements. Would this be taking advantage of the people by 'tricking them into working harder by giving them a game' or would it be viewed as something that would improve happiness at work?

  • monolithic flash photo gallery

    - by Terix
    Hi, i need to do a presentation dvd of my photos, so i would like to make a nice flash gallery with my photos embedded inside flash files, so there is no way of stealing my shoots just browsing dvd folders. Inside a dvd i'll have plenty of space so i don't care about the size of the flash file itself. There is any way to do that? Because as far as i see, all the flash galleries uses an XML file to load the images from outside, so all the shoots are jpeg put in another folder, and anyone can take them just copying the folder.

  • Custom 403 Error page not showing

    - by Rahul Sekhar
    I want to restrict access to certain folders (includes, xml and logs for example) and so I've given them 700 permissions, and all files within them 600 permissions. Firstly, is this the right approach to restrict access? I have a .htaccess file in my root that handles rewriting and error documents. There are two pages in the root - 403.php and 404.php - for 403 and 404 errors. And I have these rules added to my .htaccess file: ErrorDocument 404 /404.php ErrorDocument 403 /403.php Now, the 404 page works just fine. The 403 page does not show when I try to access the 'includes' folder - I get the standard apache 403 error page instead, saying 'Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.' However, when I try going to the .htaccess file (in the web root) in my browser, I get my custom 403 error page. Why is this happening?

  • Building the Bootsector of BIOSLOADER

    - by Kate Moss' Open Space
    Windows CE is a 32 bits OS since day one, so it makes sense tools shipped with PB, compiler, linker, assembler and etc, are for targeting to 32 bits system. But occasionally, if you are developing x86 based system and especially working on some boot code, such as boot sector of BIOSLOADER, that will be a problem. Normally, as PB provides the prebuilt boot sector image but if you ever need to rebuilt it, what should you do? You may say as it's an x86, perhaps you can use VS or Windows SDK to build it. But unfortunately, today's desktop Windows tool chains are also 32 or even 64 bits only, you need to find something older. VC++ 6.0, but how can you find one? This Website http://thestarman.pcministry.com/asm/masm.htm arranges some useful resources. Basically, you need 2 thing, the 16 bits MASM and 16 bits linker. Just make it even easier for you Download http://download.microsoft.com/download/vb60ent/Update/6/W9X2KXP/EN-US/vcpp5.exe for Assembler (MASM). Download http://download.microsoft.com/download/vc15/Update/1/WIN98/EN-US/Lnk563.exe for the Linker. And then just extract the archives and what you need is ml.exe, ml.err and link.exe

  • g++ in Knoppix 6 LiveCD

    - by HazyBlueDot
    To avoid the inevitable, let me put this in context. I am instructing an Intro to Unix course this semester and the students are using Knoppix 6.4.3 off the LiveCD. They are not required to install the system to their hard drive, and I would like to not require them to, however they do have use of a USB flash drive. This version of Knoppix seems to include gcc, but NOT g++. The course curriculum requires compiling C++ programs. I know I can run: sudo apt-get update sudo apt-get install build-essential to install (among other things) g++, but of course this only makes sense on a system installed to a hard drive. So my question is, can I write a script that calls gcc with appropriate options and flags to compile a C++ program that students could use in place of g++?

  • Getting Internal Name of a Share Point List Fields

    - by Gino Abraham
    Over the last 2 weeks i was developing a tool to migrate Lotus notes data base to Share point. The mapping between Lotus notes schema and share point list schema was done manually in an xml file for out tool. To map the columns we wanted internal names of each field. There are quite a few ways to achieve this, have explained few below. If you want internal names for one or 2 columns you can do so by navigating to the list setting and clicking on the column name. Once you are in column's details, you can check the query string of the page. The last item in the query string would be field's internal. Replace all "%5f" with '_' will give you the field internal name. In my case there were more than 80 columns. I used power shell to get the list of columns with details. Open windows Powershell and paste the following script after modifying the url and list name. [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site = new-object Microsoft.SharePoint.SPSite(http://yousitecolurl) $web = $site.OpenWeb() $list = $web.Lists["yourlist name"] $list.Fields | Format-Table Title, InternalName, TypeAsString I also found a tool in Codeplex.com which can generate a wrapper class for a list. The wrapper class will give you the guid and internal name for all fields in the list.  You can download the tool from http://imtech.codeplex.com/ Just enter the url in the text box and hit open. All the site content will be listed at the left hand side, expand the list, right click and select generate wrapper class.

  • Automate proftpd-basic install on ubuntu using apt-get

    - by Bryan
    I'm trying to build a shell script to automate the installation of several packages onto an Ubuntu 10.04 server, and I'm having problems with proftpd-basic. I'm using the command line apt-get -qy install proftpd-basic >/tmp/install.log For most packages, this approach would work fine, however proftpd-basic appears to require some interaction (it asks whether to perform an inetd or standalone installation). Is it possible for me to pre-select this option on the command line somehow, as I don't want the user to be bothered by this question? - For info, if it matters, I want to choose the 'standalone' option.

  • Free ADF Training Event in the UK

    - by Grant Ronald
    At the UKOUG conference back in December, at the Tools Roundtable session someone told me that they hadn't chosen Oracle ADF as their development environement for their future projects.  When I asked why, the response I got was "no one told us about it".  I was pretty astounded (even gobsmacked!) that the technology that is the foundation of Oracle's future applications strategy wasn't on someone's radar. There and then I promised the audience that if the UKOUG was to fill a room, I would deliver a full day of free training on Oracle ADF and JDeveloper. And here it is!  On the 11th May 2011 at the UK Oracle office in Reading I will deliver a day packed from start to finish with all the best bits of Oracle ADF and JDeveloper.  I'll build an application from start to finish, business services, validation, web services, UI, page flow, maps, graphs and show you tips and techniques.  The event in primarily focused on those who are new to JDeveloper and Oracle ADF and is aimed at getting you up to speed as quickly as possible (so others don't make the mistake of not choosing ADF ;o) ). Places are limited and are open on a first come first served basis to UKOUG members, so get registered NOW!

  • SQLAuthority News – BI Quiz Question – How to Optimize Cube? – Hints

    - by pinaldave
    I earlier wrote about SQL BI Quiz over here. The details of the quiz is as following: Working with huge data is very common when it is about Data Warehousing. It is necessary to create Cubes on the data to make it meaningful and consumable. There are cases when retrieving the data from cube takes lots of the time. Let us assume that your cube is returning you data very quickly. Suddenly on one day it is returning the data very slowly. What are the three things will you to diagnose this. After diagnose what you will do to resolve performance issue. Participate in my question over here Here is a couple of hints what I am looking for in answer: How to reach to root of slow performance? Is hardware causing the problem or something else? Is slowness is due to how cube is build and its granularity? Is underlying tables require maintenance? Is there is chance to refractor the process? Are there any tool which can help diagnosis the slowness of the cube? It is not necessary to answer all the question – but something to start with.

  • Maintenance Plan Reporting - Append To File - Clean Up?

    - by Adam J.R. Erickson
    Background: (SQL Server 2005, Standard Ed.) I have a maintenance plan running backups, taking a full backup 1/day, and t-log every 15 minutes. I have it set to create a text file report of each run, but that creates A LOT of files on the file server. These are hard to sort through, which makes them less useful. Question: There is an option in "Reporting and Logging" settings for appending all logs together, but how do you clean this out? If you're appending to the same log file every time, how should you make sure this file doesn't grow indefinitely? Is there a build-in function to clean out portions of appended logs like there is for cleaning out individual old log files?

  • Selecting a JAX-RS implementation for a new project

    - by Fernando Correia
    I'm starting a new Java project which will require a RESTful API. It will be a SaaS business application serving mobile clients. I have developed one project with Java EE 6, but I'm not very familiar with the ecosystem, since most of my experience is on the Microsoft platform. Which would be a sensible choice for a JAX-RS implementation for a new project such as described? Judging by Wikipedia's list, main contenders seem to be Jersey, Apache CXF, RESTeasy and Restlet. But the Comparison of JAX-RS Implementations cited on Wikipedia is from 2008. My first impressings from their respective homepages is that: CXF aims to be a very comprehensive solution (reminds me of WCF in the Microsoft space), which makes me think it can be more complex to understand, setup and debug than what I need; Jersey is the reference implementation and might be a good choice, but it's legacy from Sun and I'm not sure how Oracle is treating it (announcements page doesn't work and last commit notice is from 4 months ago); RESTeasy is from JBoss and probably a solid option, though I'm not sure about learning curve; Restlet seems to be popular but has a lot of history, I'm not sure how up-to-date it is in the Java EE 6 world or if it carries a heavy J2EE mindset (like lots of XML configuration). What would be the merits of each of these alternatives? What about learning curve? Feature support? Tooling (e.g. NetBeans or Eclipse wizards)? What about ease of debugging and also deployment? Is any of these project more up-to-date than the others? How stable are them?

  • MVVM Project and Item Templates

    - by Timmy Kokke
    Intro This is the first in a series of small articles about what is new in Silverlight 4 and Expression Blend 4. The series is build around a open source demo application SilverAmp which is available on http://SilverAmp.CodePlex.com.   MVVM Project and Item Templates Expression Blend has got a new project template to get started with a Model-View-ViewModel project  easily. The template provides you with a View and a ViewModel bound together. It also adds the ViewModel to the SampleData of your project. It is available for both Silverlight and Wpf. To get going, start a new project in Expression Blend and select Silverlight DataBound Application from the Silverlight project type. In this case I named the project DemoTest1. The solution now contains several folders: SampleData; which contains a data to show in Blend ViewModels; starts with one file, MainViewModel.cs Views; containing MainView.xaml with codebehind used for binding with the MainViewModel class. and your regular App.xaml and MainPage.xaml The MainViewModel class contains a sample property and a sample method. Both the property and the method are used in the MainView control. The MainView control is a regular UserControl and is placed in the MainPage. You can continue on building your applicaition by adding your own properties and methods to the ViewModel and adding controls to the View. Adding Views with ViewModels is very easy too. The guys at Microsoft where nice enough to add a new Item template too: a UserControl with ViewModel. If you add this new item to the root of your solution it will add the .xaml file to the views folder and a .cs file to the ViewModels folder. Conclusion The databound Application project type is a great to get your MVVM based project started. It also functions a great source of information about how to connect it all together.   Technorati Tags: Silverlight,Wpf,Expression Blend,MVVM

  • Android-Libgdx-ProGuard: Usefulness without DexGuard? [on hold]

    - by Rico Pablo Mince
    So I'm developing a game for Android - using LibGDX - and noticed that the Android SDK (HDK, MDK, WhatTheHellEvarDK) has ProGuard built-in. Browsing the ProGuard page is like searching Google: you get that the idea is to sell some product (in this case, it's DexGuard). That leaves me wondering what features are left out of ProGuard that a game developer targeting Android should worry about. For instance, the ProGuard FAQs answer the question: "Does ProGuard encrypt string constants?" by saying: "No. String encryption in program code has to be perfectly reversible by definition, so it only improves the obfuscation level. It increases the footprint of the code. However, by popular demand, ProGuard's closed-source sibling for Android, DexGuard, does provide string encryption, along with more protection techniques against static and dynamic analysis." Alright. OK. But isn't "...improves the obfuscation level" EXACTLY what ProGuard is supposed to do? Are there better options that can be implemented at build-time in Eclipse using the Gradle options and Libgdx? In particular, the assets folder and res-specific folders will need some protection. The code itself doesn't cure cancer, but I'd prefer if nobody could copy/paste it with different game art and call it "IhAxEdUrGamE"....

  • Remove all HTTP bindings from an IIS 6 site while leaving SSL bindings

    - by MikeBaz
    We have a (remote, via a reseller) customer who configured their IIS6 server to not have any port 80 HTTP bindings, only port 443 SSL bindings. We would like to reproduce this without going through the three layers (!) to get to the customer to test some error scenerios. However, whenever I try to get IIS to not listen on IIS at all, I can't do it. If I do it in the UI, either leaving in the main properties page, or in the advanced bindings page, the UI does not let me proceed. If I remove the HTTP ServerBindings from the metabase.xml directly, IIS makes it port 80, all unassigned addresses anyway. Is there a way to get to the "SSL only" state naturally? Please note I am NOT talking about the "require SSL" checkbox or underlying metabase setting, as that still listens on port 80 (or whatever) to give the "SSL required" error message. I'm talking about not having any bindings listed at all for HTTP.

  • Does ssh key need to be named id_rsa?

    - by dustyprogrammer
    I have come across this problem a couple of times when creating build servers with keyed authentication. I was wondering if anyone else has experience this. I have a couple of keys for my current user that may connect to different machines. Let say machine1 and machine2. I have pasted my public key into their respective authorized_keys file. The first one I have named the first key id_rsa and the second key bender. When I try to connect to bender I get the following output with my verbose ssh connection debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/bozo/.ssh/.ssh/identity debug1: Trying private key: /home/bozo/.ssh/.ssh/id_rsa debug1: Trying private key: /home/bozo/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). It only offers the id_rsa key, as you can see above. Is this correct? If so why? How do I get it to offer more keys? I know it is a problem I see intermittently, because I at home I have multiple keys without much trouble. I would also appreciate a overview on how the pub and private keys interact with the client and server. I thought I had a pretty decent idea, but apparently I am missing something. Please and thank you.

  • What is the rationale behind Apache Jena's *everything is an interface if possible* design philosophy?

    - by David Cowden
    If you are familiar with the Java RDF and OWL engine Jena, then you have run across their philosophy that everything should be specified as an interface when possible. This means that a Resource, Statement, RDFNode, Property, and even the RDF Model, etc., are, contrary to what you might first think, Interfaces instead of concrete classes. This leads to the use of Factories quite often. Since you can't instantiate a Property or Model, you must have something else do it for you --the Factory design pattern. My question, then, is, what is the reasoning behind using this pattern as opposed to a traditional class hierarchy system? It is often perfectly viable to use either one. For example, if I want a memory backed Model instead of a database-backed Model I could just instantiate those classes, I don't need ask a Factory to give me one. As an aside, I'm in the process of writing a library for manipulating Pearltrees data, which is exported from their website in the form of an RDF/XML document. As I write this library, I have many options for defining the relationships present in the Peartrees data. What is nice about the Pearltrees data is that it has a very logical class system: A tree is made up of pearls, which can be either Page, Reference, Alias, or Root pearls. My question comes from trying to figure out if I should adopt the Jena philosophy in my library which uses Jena, or if I should disregard it, pick my own design philosophy, and stick with it.

  • How to mirror filesystems with millions of hardlinks?

    - by Thomas Berger
    We have one big problem at the moment: We need to mirror a filesystem for one of our customers. Thats usual not really a problem, but here it is: On this filesystem there is one folder with millions of hardlinks (yes! MILLIONS!). rsync requires more then 4 days to just build the filelist. We use the following rsync options: rsync -Havz --progress serverA:/data/cms /data/ Has anyone a idea how to speed up this rsync, or use alternatives? We could not use dd as the target disk is smaller then the source.
