• newbie hard drive upgrade question

  - by musoNic80

  I have an Acer Aspire 3500WLMi laptop. It currently has a 40gb hard drive which I would like to upgrade. Could someone talk me through the process? I've listed my concerns/queries... Can I buy and install any 2.5" SATA or IDE hard drive into this machine? Should I buy somesort of USB caddy and clone my existing drive onto the new one via USB then physically swap the drives over? My current disk is partitioned to include a small amount of space for a Ubuntu install. Will a clone keep the current partition sizes or is it best for me to repartition once I've cloned? Many thanks.

• Undeliverable messages to newly migrated Exchange user

  - by johnnyb10

  We are in the process of migrating from our old domain to a new one, part of which involves migrating mailboxes from Exchange 2003 to Exchange 2007. A bunch of users have been migrated already without problems. However, one of the users is having trouble receiving emails from others. When someone sends to him, they get an Undeliverable NDR that says "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients." The message shows the user's distinguished name as /OU=OurDomain/CN=Recipients/CN=USER57137172. The user's account name should just be "USER", so I don't know where the extra numbers ("57137172") are coming from. Thanks in advance.

• MapReduce

  - by kaleidoscope

  MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of  intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data,  scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system. Example: A process to count the appearances of each different word in a set of documents void map(String name, String document):   // name: document name   // document: document contents   for each word w in document:     EmitIntermediate(w, 1); void reduce(String word, Iterator partialCounts):   // word: a word   // partialCounts: a list of aggregated partial counts   int result = 0;   for each pc in partialCounts:     result += ParseInt(pc);   Emit(result); Here, each document is split in words, and each word is counted initially with a "1" value by the Map function, using the word as the result key. The framework puts together all the pairs with the same key and feeds them to the same call to Reduce, thus this function just needs to sum all of its input values to find the total appearances of that word.   Sarang, K

• Installed over 4G RAM on 32-bit OS? [closed]

  - by kai

  Possible Duplicate: 32-bit Windows Server address > 4GB RAM - How? I know that for 32-bit OS, the addressable memory space for each process is "4G" (maybe just 3G in user space...). If I have a 8G RAM, is it correct that all of the processes can still utilize (shared) these 8G memory but each of them are limited to a maximum 4G? Or the whole system only can see and utilize 4G out of 8G and thus having 8G RAM on a 32-bit OS is the same as having 4G RAM on it?

• Remove Audio stream from XVID files

  - by Kyle Brandt

  I have a bunch of Xvid files that each have an audio stream that I do not want. How can I strip the audio track I don't want using the Linux command line? I don't need the whole script (loop), just what command I would use to process each avi file individually (unless the cmd itself has batch modification built into it). I don't believe the file is in an mkv container, as mkvinfo doesn't find anything. Here is part of mplayer's output (thanks ~quack): [aviheader] Video stream found, -vid 0 ID_AUDIO_ID=1 [aviheader] Audio stream found, -aid 1 ID_AUDIO_ID=2 [aviheader] Audio stream found, -aid 2 VIDEO: [XVID] 512x384 12bpp 25.000 fps 1013.4 kbps (123.7 kbyte/s)

• RHN Satellite / Spacewalk custom channels, best practice?

  - by tore-

  Hi, I'm currently setting up RHN Satellite, and all works well. I'm in the process of creating custom channels, since we have certain software which should be available for all nodes of satellite, e.g. puppet, facter, subversion, php (newer version than present in base). I've tried to find documentation on best practices on this. How should they be set up, how to handle different arch, how to handle noarch packages. How to sync updates to dependencies when updating a custom package in a custom channel (e.g. php is updated, how to fetch all updated dependencies). The channel management documentation from RHEL (http://www.redhat.com/docs/en-US/Red_Hat_Network_Satellite/5.3/Channel_Management_Guide/html/Channel_Management_Guide-Custom_Channel_and_Package_Management.html) doesn't provide me with enough information on how to solve any of theese issues. All tips, tricks and information regarding this would be great!

• Standard Network Tiers in a Distributed N-Tier System

  Distributed N-Tier client/server architecture allows for segments of an application to be broken up and distributed across multiple locations on a network.  Listed below are standard tiers in a Distributed N-Tier System. End-User Client Tier The End-User Client is responsible for sending and receiving requests from web servers and other applications servers and translating the responses so that the End-User can interpret the data effectively. The primary roles for this tier are to communicate with servers and translate server responses back to the end-user to interpret. Business-Specific Functions Validate Data Display Data Send Data to Webserver Web Server Tier The Web server tier processes new requests for information coming in from the HTTP and HTTPS ports. This primarily handles the generation of user interfaces and calls the application server when needed to access Data and business logic when needed. Business-specific functions Send Data to application server Format Data for Display Validate Data Application Server Tier The application server stores and executes predefined business logic that is applied to various pieces of data as the business determines. The processed data is then returned back to the Webserver. Additionally, this server directly calls the database to obtain and store any data used by the system Business-Specific Functions Validate Data Process Data Send Data to Database Server Database Server Tier The Database Server is responsible for storing and returning all data need by the calling applications. The primary role for this this server is storage. Data is stored as needed and can be recalled at any point later in time.

• ADF Essentials - Available for free and certified on GlassFish!

  - by delabassee

  If you are an Oracle customer, you are probably familiar with Oracle ADF (Application Development Framework). If you are not, ADF is, in a nutshell, a Java EE based framework that simplifies the development of enterprise applications. It is the development framework that was used, among other things, to build Oracle Fusion Applications. Oracle has just released ADF Essentials, a free to develop and deploy version of Oracle ADF's core technologies. As a good news never come alone, GlassFish 3.1.2 is now a certified container for ADF Essentials! ADF Essentials leverage core ADF features and includes: Oracle ADF Faces - a set of more than 150 JSF 2.0 rich components that simplify the creation of rich Web user interfaces (charting, data vizualization, advanced tables, drag and drop, touch gesture support, extensive windowing capabilities, etc.) Oracle ADF Controller - an extension of the JSF controller that helps build reusable process flows and provides the ability to create dynamic regions within Web pages. Oracle ADF Binding - an XML-based, meta-data abstraction layer to connect user interfaces to business services. Oracle ADF Business Components – a declaratively-configured layer that simplifies developing business services against relational databases by providing reusable components that implement common design patterns. ADF is a highly declarative framework, it has always had a very good tooling support. Visual development for Oracle ADF Essentials is provided in Oracle JDeveloper 11.1.2.3. Eclispe support is planned for a later OEPE (Oracle Enterprise Pack for Eclipse) release. Here are some relevant links to quickly learn on how to use ADF Essentials on GlassFish: Video : Oracle ADF Essentials Overview and Demo Deploying Oracle ADF Essentials Applications to Glassfish OTN : Oracle ADF Essentials Ressources

• It's Raining Solaris Training

  - by rajeshr

  That the popularity of Solaris 11 is only growing is clear from how regular the training sessions have been around this product. It's such an excitement to be going around sharing knowledge on Solaris, more so to explore the nitty gritty of many new and evolving features. Trust me, it's only getting better! In the process, just like in the past I stumbled on several individuals, each teaching me a lesson or two. I'm grateful. And if I've managed to get over the laziness to come back to the web logs with a collection of class photos from the last couple of months, it's because of a sense of gratitude to all 'em in the picture below. Solaris 11 Network Administration Pilot Teach in Bangalore. Sun Identity Manager (n.k.a Oracle Waveset IDM) Deployment Fundamentals Training. I'm missing from the snap because these delegates sat well over 10,000 Kms away from where I taught this class from, but were kind enough to help me associate a face with the voice by sending me a group photograph. If you want to attend one such OU program cutting down the travel, try OU's Live Virtual Class (a.k.a LVC) . Transition to Solaris 11 in Mumbai. Solaris 11 Advanced Administration Session in Bangalore. Transition to Solaris 11 in Mumbai. Attending Gary Riseborough's Exadata Training at Singapore. Solaris 11 Advanced Administration Session in Bangalore. If only the participants of each LVC session belonged to the same location, there would've been additional three group photographs occupying this space! Thank you everyone for many many memorable moments.

• website attack form submission triggering emails related questions

  - by IberoMedia

  We are experiencing website attacks that trigger the submission of a form, and send alert emails. Normal process of form submission is to fill up a couple of text fields, and when the user is redirected, the next page processes $_POST. If $_POST exists, then the email to intended form recipients is triggered. What is happening right now, we are receiving the email of the form submission, three emails at a time with same information. The information per email is the same, but not all of the spam emails contain the same information, each batch of triggered emails has unique information. The form has no captcha, and if possible we would like to keep it this way. The website has worked fine and had no spamming problems until today. We have monitoring software for the website, but whoever is submitting this form over and over is not being recorded by the tracking software WHY IS THIS? IS THE PERSON ACTUALLY VISITING THE WEBSITE? The only suspicious visit tracked was on November 10th, and this record ALSO shows three forms submitted (this is how I identified possible first visit by attacker). Then no incidents until today. WHAT IS THE GOAL of the spam attack? Is the attacker expecting us to respond to the bogus emails? What can they achieve with repeated submission of form Why are three emails triggered in the row? Is this indicative that they may be using a script? This is a PHP website. Is there a way for a client to view the PHP code of a page? Thank you

• Get songs off of Windows iPod and onto a Mac

  - by Justing

  I have been using iTunes on a Dell running Windows XP to sync about 60 gigs of songs with my old school iPod. Well, the Dell's hard drive died the other day, and the only place that I have my music is on the iPod (I do have the CDs, but really don't want to have to re-rip 60 gigs of music). So, now I have a shiny new MacBook Pro. Is there a way to get my songs off of my iPod and onto the MacBook? I googled, and found Senuti. But, I'm leery of accidentally formating the iPod and losing my songs, and I can't tell if it is Snow Leopard compatible yet. Has anyone recently gone through this process? Please provide suggestions for copying songs from an iPod formated to work with Windows onto a MacBook Pro running Snow Leopard. Thanks!

• Cutting and pasting in MS Word: hourglass pops and it takes longer than expected

  - by Rax Olgud

  I work with MS Word 2007. Today I created a new document, and for some reason cutting and pasting text (using Ctrl-X and Ctrl-V) takes longer than expected. To clarify, here's the process: I select a single word in the document I click Ctrl-X The hourglass shows up for 1-2 seconds The word is cut The same happens for pasting (i.e. 1-2 seconds of hourglass). This document is ~5 pages long, with nothing fancy. I have plenty of available RAM and my CPU usage is around 1-2%, there's not peak during the cut/paste. Any thoughts on what can cause this and what I can do against it?

• SQL Server Transaction Log RAID

  - by Eric Maibach

  We have three SQL Server servers, and each server has a about five or six databases on it. We are in the process of moving these servers to a new SAN and I am working on the best RAID configuration. Currently all of the log files for all of the databases share a RAID array, there is nothing else on this RAID array except for the log files, but all of the databases use this same array for their log files. I have read that it is best to have log files on separate disks. But in our case I am not sure whether it would be best to have one big array with about 8 drives that all the log files are on. Or would it be better to create four two disk arrays and give some of the larger databases their own dedicated disks for their log files?

• How to use launchd to ensure an application is running?

  - by zneak

  Hello guys, I use Quicksilver, which is a nifty program that really speeds up my work. I've set it to launch when I log in. However, since Snow Leopard, it's become a bit less stable, and once in a while, it crashes. And obviously, it won't restart by itself. I'm pretty sure I can use launchd to ensure it's always running when I'm logged in. Is there a good guide/example of how to make sure a process restarts when it's killed/terminated/crashed with it?

• Migrate Thunderbird 3 Saved Searches Between Accounts

  - by UltraNurd

  Long story short, the sysadmins have moved me to a new mailserver. In the process, they needed to create a separate account in Thunderbird and disable my old account. They took care of all of the mail migration. However, my saved search folders didn't go along for the ride. I have over 20 complex searches that I'd rather not have to reenter manually by hand. You can't drag saved searches between accounts like other folders. I tried closing Thunderbird, doing a find/replace in virtualFolders.dat in my Thunderbird profile folder, saving that file, and reopening Thunderbird, but that didn't appear to do anything. I'm assuming the search folders are also saved in one of the sqlite databases... does anyone know where to look?

• QuickTime X incorrect aspect ratio for H.264 video

  - by Adam Robinson

  I'm running Snow Leopard and have a serious issue with QuickTime X. I have a Samsung HMX-H100N/XAA camcorder that records H.264 video in either 720p or 1080i. In either of these resolutions, QuickTime X (and, by extension, all QuickTime-associated applications like FCP, iMovie, etc.) displays an incorrect aspect ratio for all video produced by this camcorder. For example, 720p video is reported as being 1280x720 in the movie inspector (which is normal), but the displayed size is always at an aspect ratio of something like 63:20 (never heard of such a ratio) with sizes like 1700x539. If I open the video in QuickTime 7 player on the same computer, it is displayed correctly. If I process the video through something like MPEG Streamclip to transcode it, it displays correctly. As it stands right now I have to transcode all of my video in order to use it in any iLive (or other QT-based application) unless I want it to look ridiculous. I've tried installing Perian, but that seemed to have no effect.

• How to write your unit tests to switch between NUnit and MSTest

  - by Justin Jones

  On my current project I found it useful to use both NUnit and MsTest for unit testing. When using ReSharper for running unit tests, it just simply works better with NUnit, and on large scale projects NUnit tends to run faster. We would have just simply used NUnit for everything, but MSTest gave us a few bonuses out of the box that were hard to pass up. Namely code coverage (without having to shell out thousands of extra dollars for the privilege) and integrated tests into the build process. I’m one of those guys who wants the build to fail if the unit tests don’t pass. If they don’t pass, there’s no point in sending that build on to QA. So making the build work with MsTest is easiest if you just create a unit test project in your solution. This adds the right references and project type Guids in the project file so that everything just automagically just works. Then (using NuGet of course) you add in NUnit. At the top of your test file, remove the using statements that refer to MsTest and replace it with the following: #if NUNIT using NUnit.Framework; #else using TestFixture = Microsoft.VisualStudio.TestTools.UnitTesting.TestClassAttribute; using Test = Microsoft.VisualStudio.TestTools.UnitTesting.TestMethodAttribute; using TestFixtureSetUp = Microsoft.VisualStudio.TestTools.UnitTesting.TestInitializeAttribute; using SetUp = Microsoft.VisualStudio.TestTools.UnitTesting.TestInitializeAttribute; using Microsoft.VisualStudio.TestTools.UnitTesting; #endif Basically I’m taking the NUnit naming conventions, and redirecting them to MsTest. You can go the other way, of course. I only chose this direction because I had already written the tests as NUnit tests. NUnit and MsTest provide largely the same functionality with slightly differing class names. There’s few actual differences between then, and I have not run into them on this project so far. To run the tests as NUnit tests, simply open up the project properties tab and add the compiler directive NUNIT. Remove it, and you’re back in MsTest land.

• Volume size doesn't match Disk size after gparted expansion

  - by Cybersylum

  I just expanded a basic disk on a Windows XP VM from 15gb to 40 gb using GPARTED LiveCD (0.5.2-11). I didn't notice anything unusual during the expansion; but after I rebooted back into Windows, the disk capacity doesn't match the disk size as it should (only 1 volume on the disk). The disk shows as 40gb; but the C: volume still shows the original size. I've tried expanding the disk again with GPARTED (no change), and using VMware converter and have it adjust the size of the volume during the process (complains about a lack of space of snapshot error inside the os). The volume has 27% free space so I don't think it is a space issue. Chkdsk doesn't seem to find anything wrong either. The OS seems to run just fine, it doesn't see the additional space however. Any ideas?

• Automatic server redirect that passes through as the referring site

  - by nsearle

  Hey All, As always, I would like to thank all of your help and assistance in advance. I am looking for a way to automatically redirect a user to a site and maintain the redirect site as the referral site. Let me explain the process and what is needed in a step by step format. User clicks on a desired link in an email User is navigated to testdomain.com User is automatically redirected to test.com/landing test.com sees testdomain.com as the referral site Data is gathered via Google Analytics I am unsure as if this PHP code will take care of it, or not - header("Location: http://google.com", true, 303); I could test and that is most likely what I am going to do. But I would like to understand a little more as to WHY this would or WHY this wouldn't work.

• Loadbalancing Questions

  - by Van Holtz

  I have been learning networking for about 4 months. Wrote a single standalone Multiplayer server and succeeded with authoritative approach. Now I want to extend it by splitting the single server into clusters to allow even more players to log in to avoid latency issues. Now I have protyped the Loadbalancing server and its running pretty good so far. This is my architecture, I have a master server which acts as a proxy, every sub servers(chat, login, game) connect to the master server as well as all the clients. when a client connects, Client Request: Send Request - MS(Master) - Decides which SS(SubServer) to forward to - Forwards Request to SS - SS - Analyze Message - Send Response to MS - Decides which Client to forward to - Forwards Response to Client Well, it looks like its going through lots of stages. it takes double the time to process the message than a single server approach. i feel like my model isnt the best or i may be wrong. is there any better model or the one they use in professional games? I still want a Master-SubServer approach. I just want to clarify that I'm going in the right direction before writing all my codes. Thanks for any answer :)
