• I need advice on how to debug a cluster

  - by alcor

  I'm the only developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: both servers have the same Microsoft patches/fixes, same hardware, same everything. both servers use the same memory storage (a RAID-6 through fiber channel). this software has a main module who launch the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

• SQL Server Data Type Precedence

  I am executing a simple query/stored procedure from my application against a large table and it's taking a long time to execute.

• Your favorite LiveCD

  - by sova

  Perhaps this is a question better suited for linux.se but since I have servers on all environments I was wondering what your favorite LiveCD is. Wiki defines this, for those unfamiliar, as a CD or DVD containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive. Live USB flash drives are similar to live CDs, but often have the added functionality of automatically and transparently writing changes back to their bootable medium. I tend to stick with Knoppix, and today I have to register the machine on the network before I can get any of my utilities running via IP. Any suggestions?

• Compiling old versions of R (2.11 or older) on Ubuntu 13.10 (or newer)?

  - by user283293

  I am trying to compile an old version of R (2.11.1, specifically). "Why?", you might ask. Well, I have a program I am trying to run (that was not written by me, but I am hoping to use in my research) that was written in "old" R, and the program writer has specifically mentioned that R-2.11.1 or older must be used. I have run ./configure with no obvious errors (the entire output being far too long to post here, but I have been warned that I cannot make PDF, DVI, or HTML versions of the help pages, which I'm not too concerned about). Next, when I pass the make command, I am met with the following error (after a long stream of successful commands): Warning in solve.default(rgb): unable to load shared library '/home/sbowerma/Programs/R-2.11.1/modules//lapack.so': /home/sbowerma/Programs/R-2.11.1/lib/libRlapack.so: undefined symbol: _gfortran_compare_string Error in solve.default(rgb) : lapack routines cannot be loaded Error: unable to load R code in package 'grDevices' Execution halted However, I have confirmed that the library lapack.so is, in fact, in the exact position it is supposed to be.

• GlassFish Community Event @ JavaOne - Save the date!

  - by alexismp

  The interest for having a GlassFish community event at JavaOne is still very strong both inside Oracle and in the community, so this year again we'll be hosting a get together on the Sunday prior to the main event. If you're in town and attending JavaOne, mark your calendars : Sunday 2nd, October 2011 - 12:30pm-4:30pm in the Moscone This will be an opportunity to discuss the community status (adoption of Java EE 6, GlassFish 3.1.x) and hear about future plans, mainly around Java EE 7 and the related GlassFish release(s). We'd also like to have several participants share their deployment stories as well as some time for an free-form unconference format and some team building activity. Of course, beyond all the content shared in slides, this should really also be a good excuse to meet folks from the community and from the core GlassFish team at Oracle. Here's a post on last year's event. And before anybody asks, we are still exploring the party situation :-)

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• Subdomains vs. URL Path in shareable links

  - by Adam Matan

  I am building a web application for questions and answers. Each question/answer page has all the required metadata for Facebook and Twitter, and we encourage users to share these pages. I have a dilemma regarding the shared link structure: Option 1 - subdomains Use a questions.example.com and answers.example.com, followed by an ID and optional text. The text is ignored by the request, which only takes the id into account. http://questions.example.com/<question_id>/<question_text> http://questions.example.com/12345/how-long-is-the-queue # Example http://q.example.com/12345 # Example Option 2 - URL path This is the format used by stackoverflow.com and trello.com: http://example.com/questions/<question_id>/<question_text> http://example.com/questions12345/how-long-is-the-queue # Example http://example.com/q/12345 # Example Server-wise, I can easily do both - I have a wildcard SSL certificate and Apache/NGinx configuration is pretty straightforward. Which option - subdomains or URL path - is preferred for shareble links?

• Managing different utility classes between engine and libraries

  - by hayer

  I'm currently in updating some engine code (which does not work, so it is more like creating a engine). I've decided to swap over to SFML (instead of my own crappy renderer, window manager, and audio), Box2D (since I need physics, but have none), and some small utilities I've built myself. The problem is that each of the project mentioned over use different types for things like Vector2, etc. So to the question: is it a good idea to replace Box2D and SFML vectors with my own vector class (which is one of my better implementations)? My idea then was to have a separate .lib with all my classes that should be shared between all the projects in the solution.

• Need suggestions on what you regard as &ldquo;security&rdquo;

  - by John Breakwell

  I’m currently writing a large piece on MSMQ security and wanted to check I was covering the right areas. I have some doubts as I’ve seen the occasional MSMQ forum question where a poster has used the word “security” in different contexts to what I was expecting. So here are the areas I plan to cover: Message security encryption on the wire (SSL and IPSEC) encryption of the message (MSMQ encryption) encryption of the payload (data encryption) signing and authentication Queue security SIDs and ACLs Discoverability Cross-forest issues Storage security NTFS permissions unencrypted data Service security Ports and Firewalls DOS attacks Hardened mode (HTTP only) RPC secure channel requirement authenticated RPC requirement Active Directory object permissions Setup Administrator requirements What else would you want to see?

• How to set up Ubuntu Server as a NAS?

  - by rifferte

  I am looking to set up Ubuntu Server as a headless NAS for my home. I would like to have file storage there, as well as a central hub for my MP3s and pictures. What are the best packages out there to handle this? Can someone post a link to a good tutorial or post some tips? One constraint I have is that it has to be Windows 7 friendly. By that I mean the shares and streaming should work for a Windows machine.

• How to access the SD card through my Sony Ericsson Xperia Arc Phone?

  - by user16364

  I have a Sony Ericsson Xperia Arc phone and I cannot access its SD card through the USB cable provided. I have set the USB connection mode to MSC yet when I connect the phone to my computer I cannot see the SD card (or anything for that matter). The Disk Utility however, does see an SEMC Mass Storage device but it says that no media was detected. I have validated that the SD card works as I removed it from the camera and plugged it into a card reader and saw all the photos and files stored on it. I have validated that the phone works as I have connected it (in MSC mode) to my wife's Windows 7 computer. Can anyone please tell me how I can access the SD card on my phone.

• More than 2gb of Music without paid plan possible?

  - by user8007

  Hi there, I do not have a paid plan for UbuntuOne and do not intend of buying one, but I do like to buy music from the UbuntuOne Music Store. Is it possible to buy music, once I bought more than 2gb or would I have to move the music out of the UbuntuOne share? In this case, I would suggest to put the music in the official ubuntuone-folder instead of a hidden one. Non-technical users will not understand, why their shared music files are not in this folder, but others are popping up there (e.g. in the webinterface). Best Regards, Lars

• Implementing unlockable items on Android

  - by coder_For_Life22

  I know this would be a beginners question (some of you might think) but I would like to know different approaches for this. I have a game with lets say 20 unlockable items, at the main menu I have a button where the user can go to an activity and view the unlockable items. So I would like for it to have a "Locked image" and under it a text telling you what the item is and maybe how to unlock it. What is the best way of going about this? And then when the item is unlocked during the game, maybe put a variable in the shared preference and check at the beginning of the activity with the unlockabled items. Let me know what you guys think. Thanks.

• (My) Sun Ray 3i

  - by user13346636

  Last week, some Sun Ray devices were shown at the LASDEC exhibition. Afterward, they were brought back to the Aoyama Center, but not all of them found a place to be stored. So, two days ago, Iwasaki-san, one of the co-workers I've been close to (and who was at the exhibition), put a Sun Ray 3i (all-in-one with 21.5" screen) on my (shared) desk. Yay! I managed to get a Japanese keyboard, and now I can access my card and cardless sessions from Germany, and the performance is just great, as good as when I work from home in Hamburg. That's the way my deskt looks now,almost as messy as my desk in Hamburg: And my back is very grateful.

• Quality web hosts not using c panel [closed]

  - by J4G

  Possible Duplicate: How to find web hosting that meets my requirements? I was an iPower web hosting user before I encountered major problems with their MySQL databases. I recently tried A Small Orange, whose GUI was not compelling, and I quickly learned to loathe c panel. I looked into using GoDaddy, but reviews of their service have been very negative. I was satisfied with iPower's control panel, so something similar would be appropriate. Can anyone recommend a quality web host that includes the following features? *Unlimited bandwidth (200gb or higher) *Unlimited storage (10gb or higher) *High up-time (preferably 95% or higher) *Does not use C panel or other difficult-to-use control panels *Supports multiple MySQL databases *Uses a recent version of PHPmyAdmin

• New .Net Authentication in 4.5.1

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/11/05/new-.net-authentication-in-4.5.1.aspxThere has been a lot of traffic on my post about Simple Membership that came with the File new Project MVC 4 in 2012. I was reading the release notes for Visual Studio 2013 and .Net 4.5.1 and it mentioned a new/updated Authentication approach. “ASP.NET Identity is the new membership system for ASP.NET applications. ASP.NET Identity makes it easy to integrate user-specific profile data with application data. ASP.NET Identity also allows you to choose the persistence model for user profiles in your application. You can store the data in a SQL Server database or another data store, including NoSQL data stores such as Windows Azure Storage Tables” There’s a great page on the asp.net site that gives an introduction, overview, how to use it, and how to migrate to it. I won’t be doing a new project for awhile at work, but I’ll definitely be looking into this more when I get the time.
