• How to search unique dynamic data in a sheet and then copy relevent row in diffrent sheet?

  - by Hemant

  I am getting data from internet (DataFrom Web) In sheet1. Then I disperse that data in to three sheets based on three unique text. Like a,b and c. Rows are copied to sheet a,b and c sheets depending on text (a,b,c) they have. All the rows have one unique text (like url) by which they can be searched. I have added static data corresponding to the row. The problem is when ever internet data is changed (row addition/substitution or randomized). My static data loses its connection with the original row for which it was written. I want to search the data based on one unique key and put it to its original place where it used to be with static data.

• Openfire Installation Issue - Can't Login to admin panel

  - by Lobe

  I am trying to get Openfire to install on an Ubuntu virtual machine, however upon completing the web based installer, I am unable to login to the admin panel. So far I: downloaded Debian installer Installed using stock options Added database and built the structure using supplied SQL file Completed web based installer I am now trying to login using username: admin and my password, however I constantly get a wrong username/password error. There is a record generated in the MySQL database showing the admin user with an encrypted password, and changing to an unencoded password doesn't work. What is the problem here?

• Updating windows xp hard drive controller from ubuntu live disk

  - by Joel

  The problem: When booting, I get a blue screen shortly after the Windows XP logo splash screen. The error code is 7b, and the second hex number is 0xC0000034. Based on this link (item 7) it appears the driver should be updated. Oddly, I made no changes to the drivers recently. I suspect it was something in a windows update or the newest upgrade of my antivirus (eset). But I digress. The BSOD makes me unable to boot into Windows at all, so I can't update the driver from there. I've run various bios-level diagnostics (including full surface scan) and the hd looks good. I'm also able to boot to an old ubuntu disk and read files from the hd. The question: Based on the above, it appears that I need to update the Windows hard drive controller from the ubuntu live disk. How do I do that?

• What is a Windows text editor that will make it easy for me to have four text files open onscreen at once?

  - by Ascendant

  When brainstorming / planning I like to have four text files open onscreen at once: One for notes/stream of consciousness, one for action items to follow up on, one for a rough outline, etc.... What I'm looking for is an easy way to create / save four text files in this manner in Windows. Most importantly, I need the lines to wrap based on the width of the actual window itself. Not based on a ruler or document size (a la Word or WordPad) and not wrapping "manually only" (like Windows' built in Notepad application.) Also, I need the windows to have no, or at least, little, fluff at the top of each document (menubars, ribbons, etc.) On my Mac, I've found that the built-in TextEdit application is almost perfect for this. There's no header or ribbon taking up space for each document, and lines wrap when they hit the end of the window. I haven't had any luck finding a Windows application that works the same way.

• Remote X-windows between new RHEL5 and old Solaris 8

  - by joshxdr

  I have a very small lab network with three boxes: a modern x86-based RHEL3 box, an x86-based RHEL5 box, and a 1998-vintage SPARC Ultra5 with Solaris 8. I can use ssh -X to run a program on the RHEL5 box and view the windows on the RHEL3 box. I believe this uses xauth and magic cookies?? I have followed the X-Windows HOWTO to set up xauth on the Solaris box, but so far no dice. I would like to be able to use the X-windows server on the RHEL3 box with a client program on the Solaris box (program running on Solaris host, windows appearing at Linux host). Is there a trick to this, or have I made a mistake following the instructions for setting up xauth and magic cookie?

• What is the Optimal Server Configuration for Split-Path Testing?

  - by doug

  I am far from an expert on Apache or any server for that matter, so i apologize if this question is poorly worded, which it likely is. We have always relied on a vendor for split-path testing (aka "AB Testing"). If you're not familiar with that term, it's a form of marketing research in which you slightly modify one of your web pages (usually one nearest the point of conversion), say for instance, by changing the position of the "Buy Now" button or its color/contrast/texture, then serving one of those two pages to a given user based on random selection. By doing split-path testing ourselves, I suspect we can do it far more cheaply and increase cycle times as well. What is the optimal set-up for these tests? "Optimal" is based on the following criteria: how quickly/easily new tests can be set-up and put online; and minimal disruption to overall site performance

• Sorting for 2D Drawing

  - by Nexian

  okie, looked through quite a few similar questions but still feel the need to ask mine specifically (I know, crazy). Anyhoo: I am drawing a game in 2D (isometric) My objects have their own arrays. (i.e. Tiles[], Objects[], Particles[], etc) I want to have a draw[] array to hold anything that will be drawn. Because it is 2D, I assume I must prioritise depth over any other sorting or things will look weird. My game is turn based so Tiles and Objects won't be changing position every frame. However, Particles probably will. So I am thinking I can populate the draw[] array (probably a vector?) with what is on-screen and have it add/remove object, tile & particle references when I pan the screen or when a tile or object is specifically moved. No idea how often I'm going to have to update for particles right now. I want to do this because my game may have many thousands of objects and I want to iterate through as few as possible when drawing. I plan to give each element a depth value to sort by. So, my questions: Does the above method sound like a good way to deal with the actual drawing? What is the most efficient way to sort a vector? Most of the time it wont require efficiency. But for panning the screen it will. And I imagine if I have many particles on screen moving across multiple tiles, it may happen quite often. For reference, my screen will be drawing about 2,800 objects at any one time. When panning, it will be adding/removing about ~200 elements every second, and each new element will need adding in the correct location based on depth.

• Tracking "To Do" Items

  - by Bill Graziano

  One of the challenges I struggle with is keeping a good "to do" list of things I need to do on the various SQL Servers I support. I have servers that I don't visit on a regular basis so my situation may be different than many of you. Though I'm sure you all have servers that you only touch every few months. (And it's usually the accounting server!) It's difficult for me to remember what changes I made and what changes I need to make. I've tried Outlook, OneNote and various other to do list managers and haven't been happy with any of them. Many are close but just don't give me what I need. As a result I've started writing my own. It's web-based so you can use it from anywhere -- including on a server. It also knows just enough about SQL Server to help structure your to do items and your notes. It isn't agent based and doesn't do any monitoring. Think OneNote or Evernote but with some "SQL Servery" stuff built in. If you'd like to try this or take a survey I'm putting together, add your email address to my mailing list.  I should be ready in a week or so.  I'm only going to use this list for notifications about this service. I'd like to find a small group of people that feel the same pain I do and maybe we can build something interesting.

• FreeNAS/ZFS/Raid-Z slightly different disks

  - by muskratt

  I'm considering using FreeNAS and "recycling" some of my older 1TB disks. Two are the exact same model Western Digital while another is Seagate and the fourth is Samsung. Typically, since all disks are not equal, I'll create my arrays on a Windows-based server 1GB undersized to prevent a replacement disk not being large enough. Dell is notorious for sending replacement SATA disks of different brand---knock on wood, no problems yet. Since not all drives are created equally and they can vary a few MBs, is there a way to make the the FreeNas/ZFS/Raid-Z function in the same way I do for my Windows-based servers above? Thanks

• Reliable 1tb or larger hard drive?

  - by jasondavis

  I am in the market for 2-3 new drives, I would like each to be at least 1tb to 2tb in size. I have been reading all the reviews on newegg.com for 1tb and larger drives and they all have 1 thing in common. Almost all the ones I read about have complaints of them being DOA or dieing within a few weeks of use. I am hoping to find some drives with this storage range that have a reputation for lasting a long time instead of a short life. Please help me if you have any experience with these sort of drives? Most the ones I read about were Western Digital brand. I realize some might complain that this questions answer would be based upon a timeframe, so if a user searches and find this answer a year from now it will be outdated but I would appreciate any help based on the current hard drives available as of April 10th, 2010 on newegg.com

• I need a form to tie MySQL Records together.

  - by John R

  I need a HTML-based form to tie database records together. The user scenario that I envision is somthing like this: A super-user does a search of the database and is delivered a table of records based on that search; each record is numbered with the database-record id. There would also be two text fields next to each record. These text fields would allow: the user to make a reference from one record to another. For example, a user could enter into record id #457 the integer 242 to indicate that there is a correlation with record ID #242. The user would also describe the type of relationship it is. This could be accomplished with a simple integer in the second field that indicates the type of relationship between the two records. When the super-user hits the submit button, all of these relationships are saved in a mySqljoin table. One option is to give me advice on how to implement and code this myself in PHP. However, before I reinvent the wheel, another option is to lead me to a free script that does something similar.

• Looking for MRP software

  - by Samuel

  I am looking for MRP software. All the stuff I have found so far looks like it's from the 90's and has that very old person business feel. I want something fresh and new. I would prefer an open source, web based solution. PHP/MySQL would be best but not required. I couldn't find anything that was web based that didn't make me want to cry. Superuser doesn't have a lot of eye candy but it still looks great. I am the web developer at my company so if I don't find anything I will be making it my self (well, try to at least).

• Matrices: Arrays or separate member variables?

  - by bjz

  I'm teaching myself 3D maths and in the process building my own rudimentary engine (of sorts). I was wondering what would be the best way to structure my matrix class. There are a few options: Separate member variables: struct Mat4 { float m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44; // methods } A multi-dimensional array: struct Mat4 { float[4][4] m; // methods } An array of vectors struct Mat4 { Vec4[4] m; // methods } I'm guessing there would be positives and negatives to each. From 3D Math Primer for Graphics and Game Development, 2nd Edition p.155: Matrices use 1-based indices, so the first row and column are numbered 1. For example, a12 (read “a one two,” not “a twelve”) is the element in the first row, second column. Notice that this is different from programming languages such as C++ and Java, which use 0-based array indices. A matrix does not have a column 0 or row 0. This difference in indexing can cause some confusion if matrices are stored using an actual array data type. For this reason, it’s common for classes that store small, fixed size matrices of the type used for geometric purposes to give each element its own named member variable, such as float a11, instead of using the language’s native array support with something like float elem[3][3]. So that's one vote for method one. Is this really the accepted way to do things? It seems rather unwieldy if the only benefit would be sticking with the conventional math notation.

• Windows Web Server in DataCenter Authenticate with AD in Office

  - by Viper Venom

  Hi, We would like to have put a File Server in DataCentre to allow user to upload/download files when they are home. Since we have hundreds of users and would like to let the user to authenticate with the existing AD in our office. Basically, I will setup the IIS server to allow users to list various directories in the File Server based on their user group. For example, Group A will have list the D:\Files\A and the Group B will have list the D:\Files\B ...etc. After some initial study, I found that the PPTP based Site to Site VPN might fit our need to do the authentication part but I still don't have any idea on how to let them upload files to the server. Is there any suggestions such as any better option to do this (either authentication or upload part) or any area I need to be careful of? Thank you in advance.

• Mozilla Persona to the login rescue?

  - by Matt Watson

  A lot of website now allow us to login or create accounts via OAuth or OpenID. We can use our Facebook, Twitter, Google, Windows Live account and others. The problem with a lot of these is we have to have allow the websites to then have access to our account and profile data that they shouldn't really have. Below is a Twitter authorization screen for example when signing in via Technorati. Now Technorati can follow new people, update my profile and post tweets? All I wanted to do was login to Technorati.com to comment on a post!Mozilla has just released their new solution for this called Persona. First thought is oh great another solution! But they are actually providing something a little different and better. It is based on an email address and isn't linked to anything like our personal social networks or their information. Persona only exists to help with logging in to websites. No loose strings attached.Persona is based on a new standard called BrowserID and you can read more about it here:How BrowserID Works.  The goal is to integrate BrowserID in to the browser at a deeper level so no password entry is required at all. You can tell your web browser to just auto sign in for you. I am really hoping this takes off and will look at implementing it in current projects! I would recommend researching it and lets hope it or something like it becomes a wide spread reality in the future.

• Designing a system with different business rules for different customers

  - by user1595846

  My company is rewriting our proprietary business application. The current architecture is poorly done and inflexible. It is coded more procedural oriented as opposed to object oriented. It has become difficult to maintain. Our system is a web application written in .Net Webforms. I am considering ASP.Net MVC for the rewrite. We intend to rewrite it with a good, solid architecture with the goal of maintainability and reusable classes for some of our other systems and services. We would also like the system to be customizable for different customers in the event that we market the system. I am considering redesigning the system based on the layered architecture (Presentation, Business, Data Access layers) described in the Microsoft Patterns and Practices Application Architecture Guide. http://msdn.microsoft.com/en-us/library/ff650706.aspx Hopefully this isn't too open ended, but how would you recommend allowing for different business logic/rules for different customers? I'm aware of Windows Workflow Foundation, but from what I've read about it, it seems many business rules could be too complicated to handle there. Also, Can anyone point me to where I can download an example of a .net solution that is based on the Application Architecture Guide? I have already downloaded the Layered Architecture Solution Guidance and the Expense Sample on codeplex. I was looking for something a bit larger and more robust that I could step through the code and see how it works. If you feel there are better architectures to base our redesign on please feel free to share. I appreciate your help!

• My Obligatory IPad Post

  - by mark.wilcox

  I've had my IPad for about a week now. So I thought I'd write some thoughts down based on my initial experiences. Here are my initial take-aways: 1 - Netflix OnDemand - I'm a movie junkie. I'm now more apt to just start a movie as background sound for my workday (I telecommute - so except for the occasional bark from my dog, it's awfully quiet here if I don't have something going). 2 - The Email Client is really nice and I'm as fast or faster typing when I have the wireless keyboard engaged. Even with onscreen keyboard - I'm already close to 75% of desktop speed 3 - The battery life is incredible - I think this is the first case where a mobile device actually under-promised on battery 4 - It totally has killed the notion of using a normal PC for my wife and mother-in-law - neither of which had wanted an iPhone/iPod Touch or really any Apple device until they got to play with my iPad. The concept of - instant on, easy to hold and touch-based navigation has them hooked. Heck, it has me hooked. My ultimate goal is to be able to have it at least replace the need to take my netbook with me on the road. I haven't had a chance to complete my testing on that front yet - between work, my wife traveling (for a change) and now my wife home sick - I haven't had time to just play with it. But so far my only regret - that I haven't already bought two more for everyone else in my family who wants to use mine. Posted via email from Virtual Identity Dialogue

• Is Page-Loading Time Relevant?

  - by doug

  Take this (ServerFault) page for instance. It has about 20 elements. When the last of these has loaded, the page is deemed "loaded"--but not before. This is certainly the protocol used by our testing service (which is among the small group of well-known vendors that offer that sort of service). Obviously this method is based on a clear, definite endpoint--therefore it's easy to apply w/ concomitant reliability. I think it's also the metric used by the popular Firefox plugin, 'YSlow.' For my employer's website, nearly always the last-to-load items are tracking code, tracking pixels, etc., so from the user's point of view--their perception--the page was "loaded" well before it had actually loaded based on the criterion used by our testing service (15-20% is a rough estimate). I'm sure i'm not the first person to consider this nor the first to wonder if it is causing micro-optimization while ignoring overall system-level, or user-perceived performance. So my question is, are there are other more practical (yet still reasonably precise) measures of page loading time?

• Running a webserver behind a firewall, is it secure?

  - by i.am.intern

  Currently we have a Linux-based firewall which NAT-ing our public IP address to give internet access to our staff's PCs and a Windows Server 2003 for internal filesharing. I want to host Redmine/SVN (a bugtracker) internally behind this firewall using a Linux server. This webserver will be accessed by our clients externally so they can post bug reports. This means that I have to open port 80 & 22 at the firewall to give access to the webserver and me to SSH it from home. However, let's say I'm using password-based SSH for the webserver and somebody cracked it. Does that mean the cracker could ping and access other servers and PCs in the network?

• Can't ssh from Ubuntu to RHEL or CentOS

  - by Alex N

  I am trying to setup publickey based authenitcation for 2 different boxes. One RHEL another on e is CentOS. I am having same issue with both where ssh fails and falls back to password based authentication. Error that seems to be causing this is quite obscure: debug1: Unspecified GSS failure. Minor code may provide more information Credentials cache file '/tmp/krb5cc_1000' not found Both boxes are completely unrelated. I have my public key in .ssh/authorized_keys file on both boxes, all permissions are checked and good(700 for .ssh and 600 for internals) I have bunch of other servers that are running on various flavors(Gentoo, Fedora, FreeBSD etc.) and publickey ssh works just fine, but CentOS and RHEL giving me this for some reason :( Anyone experienced this before? I am not even sure how to further analyze this issue :(

• Artists and music - i need help to decide wich cms to use.

  - by infty

  A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own, smaller, gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implementet all of these features, but i want to use an existing content managment system for all of these features so that future devolpers can, hopefully, more easy extend the website. And also, so that i dont have to provide to much documentation. I have never developed a website using an external cms like drupal or wordpress and after seeing hours of tutorial videos of both systems, i still cant make up my mind on wheter i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can only imagine that staff members would also want to create content using iphone or android based mobile devices. But this is not a required feature. Can someone, with experience, please tell me about their experiences with bigger projects like this? The site will approx. have a total of 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

• Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

  - by Johnnylight

  After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?
