• Office 2007 install limits?

  - by AppsByAaron

  I've been able to install Office 2003 on a couple of computers that I own without any trouble. However, I just got office 2007 and I'm not able to install it on my computer and my laptop. I know this may violate agreements and whatnot but I'm curious to know if this is something that Microsoft has finally started to crack down on or what. Any information is help full. And I know that I'm going to get a few answers telling me that I'm "stealing" or whatever so I don't need to hear about that. thanks. ;)

• How to configure Amazon Security Groups to achieve multi-tier architecture?

  - by ks78

  What is the preferred way to configure Amazon Security Groups to achieve a multi-tier architecture? Each of my instances has its own Security Group, which I only want to use for rules specific to an instance. I'd like to keep any rules which apply to multiple instances in a separate Security Group, which can then be assigned to instance Security Groups as necessary. As an example, I've setup a group called "admin", which allows administrative access from my IP. I added the "admin" group as the source to each of my instance security groups. However, I still can't access the instances from my IP without adding the rules directly to the instance's group. Am I missing something? Although it seems a multi-tier security architecture should be possible, it doesn't seem to be working.

• Any ideas about how to make Programming Techniques Class more interesting.

  - by Eedoh

  Hello. I already found similar question here on SO, but almost all the answers were more philosophical, then practical. I'd like You to share some of Your PRACTICAL ideas about how to make my course more interesting. It doesn't matter how much effort it takes from me. I even thought about trying to motivate them to pick some topic in the beginning of the course and to work on it as some kind of real, small, startup project that they could maybe financially exploit once it's finished. But I'm afraid that most of them will not get the project to the end, and that it could be boring to them working on one thing all year long. Also I thought about involving them in Torcs, but I'm afraid most of them wouldn't be up to the task. Btw, Torcs is Car Racing Simulation, but there's an API for developers so they can develop their own AI for the driver, and then race their cars against the other programmer's AI's. I'm not asking here for problem examples, as I asked a separate question about that. I need ideas about making my lectures more interesting and fun.

• How to manage drawing loop when changing render targets

  - by George Duckett

  I'm managing my game state by having a base GameScreen class with a Draw method. I then have (basically) a stack of GameScreens that I render. I render the bottom one first, as screens above might not completely cover the ones below. I now have a problem where one GameScreen changes render targets while doing its rendering. Anything the previous screens have drawn to the backbuffer is lost (as XNA emulates what happens on the xbox). I don't want to just set the backbuffer to preserve its contents as I want this to work on the xbox as well as PC. How should I manage this problem? A few ideas I've had: Render every GameScreen to its own render target, then render them all to the backbuffer. Create some kind of RenderAction queue where a game screen (and anything else I guess) could queue something to be rendered to the back buffer. They'd render whatever they wanted to any render target as normal, but if they wanted to render to the backbuffer they'd stick that in a queue which would get processed once all rendertarget rendering was done. Abstract away from render targets and backbuffers and have some way of representing the way graphics flows and transforms between render targets and have something manage/work out the correct rendering order (and render targets) given what rendering process needs as input and what it produces as output. I think each of my ideas have pros and cons and there are probably several other ways of approaching this general problem so I'm interested in finding out what solutions are out there.

• How to make Box2D bodies automatically return to a initial rotation

  - by sm4

  I have two long Box2D bodies, that can collide while moving one of them around with MouseJoint. I want them to try to hold their position and rotation. Blue body is moved using MouseJoint (yellow) towards the Red body. Red body has another MouseJoint - Blue can push Red, but Red will try to return to the start point thanks to the MouseJoint - this works just fine. Both bodies correctly rotate along the middle. This is still as I want. I change the MouseJoint to move the Blue away. What I need is both bodies return to their initial rotation (green arrows) Desired positions and rotations Is there anything in Box2D that could do this automatically? The MouseJoint does that nicely for position. I need it in AndEngine (Java, Android) port, but any Box2D solution is fine. EDIT: By automatically I mean having something I can add to the object "Paddle" without the need to change game loop. I want to encapsulate this functionality to the object itself. I already have an object Paddle that has its own UpdateHandler which is being called from the game loop. What would be much nicer is to attach some kind of "spring" joint to both left and right sides of the paddle that would automatically level the paddle. I will be exploring this option soon.

• How can I join non-consecutive partitions on internal hard disk?

  - by Andy

  I recently installed a new, larger hard disk in my PC at work (the office wouldn't spring for an upgrade for my 75GB disk, so I brought my own 2TB disk in from home). I managed to clone the original drive using CloneZilla, but now I have a 75GB partition on my new drive, followed by a 300MB partition, followed by a 1794.65GB of unallocated space. What I want is to add the unallocated space to the 75GB partition, thereby maximizing my C: drive. However, when I right-click on the C: partition, the option to "Extend Volume" is grayed out. How do I get all my fancy new extra space to be part of my C: drive? I also tried booting with GParted, but I get the same deal - cannot adjust the C: drive because there's no contiguous space.

• Oracle Database 12c and Oracle Solaris 11 DTrace

  - by Larry Wake

  As you may have heard, Oracle Database 12c is now available for Oracle Solaris and Oracle Linux. Among other things, that means we now have the opportunity to share some of the cool things the Oracle Database and Oracle Solaris engineering teams have been doing together. And here's a good one: In this screencast, Jon Haslam describes how on Oracle Solaris 11, DTrace is now integrated into Oracle Database V$ views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself: With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. This is a great example of the power of DTrace, which is just about to celebrate its 10th anniversary in the wild. The screencast has some nice examples of DTrace's power on its own, as well as diving into the DTrace/Oracle Database 12c synergy. There's more, of course.  Over on the OTN Garage blog, Rick Ramsey has put together a nice compendium of ways the OS makes the database scream, and Ginny Henningsen's written an article on the same topic.  And, we've also got an OTN page that digs further into Oracle Database / Oracle Solaris synergies.

• Cant deploy "war" file from Virtual Hosts, see a directory listing.

  - by Kaustubh P

  This is my httpd.conf configured with Virtual hosts: NameVirtualHost *:80 <VirtualHost *:80> ServerName http://foo.baz.in DocumentRoot /var/www/foo/ </VirtualHost> <VirtualHost *:80> ServerName http://bar.baz.in DocumentRoot /var/www/ </VirtualHost> The second virtual host is a Wordpress blog, configured with .htaccess, and index.php in the root i.e. /var/www, and rest of the files in wordpress's own folder. However, the first virtual host is a "war" file, and when I goto foo.baz.in, I see the directory listing, containing the war. I also tried changing the DocumentRoot to /var/www/foo/foo.war` but I get an error Restarting web server: apache2Warning: DocumentRoot [/var/www/foo/foo.war] does not exist I also changed the owner and permission of the war to www-data:www-data and changed the permissions to 755, but to no avail. How do I make apache deploy my "war"? Thanks.

• 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?

• Do you know about the Visual Studio ALM Rangers Guidance?

  - by Martin Hinshelwood

  I have been tasked with investigating the Guidance available around Visual Studio 2010 for one of our customers and it makes sense to make this available to everyone. The official guidance around Visual Studio 2010 has been created by the Visual Studio ALM Rangers and is a brew of a bunch of really clever guys experiences working with the tools and customers. I will be creating a series of posts on the different guidance options as many people still do not know about them even though Willy-Peter Schaub has done a fantastic job of making sure they get the recognition they deserve. There is a full list of all of the Rangers Solutions and Projects on MSDN, but I wanted to add my own point of view to the usefulness of each one. If you don’t know who the rangers are you should have a look at the Visual Studio ALM Rangers Index to see the full breadth of where the rangers are. All of the Rangers Solutions are available on Codeplex where you can download them and add reviews… Rangers Solutions and Projects Do you know about the Visual Studio 2010 Architecture Guidance? More coming soon… These solutions took a very long time to put together and I wanted to make sure that we all understand the value of the free time that member of The Product Team, Visual Studio ALM MVP’s and partners put in to make them happen.

• Recording slow web stream

  - by Budric

  I'm trying to record an mpeg2 video stream from a website that doesn't have the greatest bandwidth. The video often buffers. I want to download the stream and watch it offline.

• Removing vg and lv after physical drive has been removed

  - by Rene

  We had a disk fail and replace but forgot to vgreduce first. The drive was on it's own VG and with two empty LV's and these are now causing LVM to complain every time any command is run, i.e. # lvscan /dev/vg04/swap: read failed after 0 of 4096 at 4294901760: Input/output error /dev/vg04/swap: read failed after 0 of 4096 at 4294959104: Input/output error /dev/vg04/swap: read failed after 0 of 4096 at 0: Input/output error /dev/vg04/swap: read failed after 0 of 4096 at 4096: Input/output error /dev/vg04/vz: read failed after 0 of 4096 at 995903864832: Input/output error /dev/vg04/vz: read failed after 0 of 4096 at 995903922176: Input/output error /dev/vg04/vz: read failed after 0 of 4096 at 0: Input/output error /dev/vg04/vz: read failed after 0 of 4096 at 4096: Input/output error The two LV's are not important, I just want to stop this error from displaying.

• Software Design Idea for multi tier architecture

  - by Preyash

  I am currently investigating multi tier architecture design for a web based application in MVC3. I already have an architecture but not sure if its the best I can do in terms of extendability and performance. The current architecure has following components DataTier (Contains EF POCO objects) DomainModel (Contains Domain related objects) Global (Among other common things it contains Repository objects for CRUD to DB) Business Layer (Business Logic and Interaction between Data and Client and CRUD using repository) Web(Client) (which talks to DomainModel and Business but also have its own ViewModels for Create and Edit Views for e.g.) Note: I am using ValueInjector for convering one type of entity to another. (which is proving an overhead in this desing. I really dont like over doing this.) My question is am I having too many tiers in the above architecure? Do I really need domain model? (I think I do when I exposes my Business Logic via WCF to external clients). What is happening is that for a simple database insert it (1) create ViewModel (2) Convert ViewModel to DomainModel for Business to understand (3) Business Convert it to DataModel for Repository and then data comes back in the same order. Few things to consider, I am not looking for a perfect architecure solution as it does not exits. I am looking for something that is scalable. It should resuable (for e.g. using design patterns ,interfaces, inheritance etc.) Each Layers should be easily testable. Any suggestions or comments is much appriciated. Thanks,

• Page appears indexed in Google but not findable for any search terms?

  - by Jeff Atwood

  (Note that I am going to use screenshots here because I suspect writing about this will change the behavior over time.) If you do a Google search for uiviewcontroller best practices either with or without the quotes, you end up with results like this: Note that none of these pages resolve to the actual Stack Overflow question containing those words in the title. They resolve to either a) sites that are mirroring our creative commons data and correctly pointing back to the source question without nofollow, as properly specified by our attribution requirements or b) our own internal links to the question, but not the actual question itself. The actual page with the title ... Custom UIView and UIViewController best practices? ... does exist at this URL ... http://stackoverflow.com/questions/3300183/custom-uiview-and-uiviewcontroller-best-practices ... and apparently it is present in Google's index! But why does it not appear when we search for uiviewcontroller best practices ? We know that Google contains this page in its index Our search terms match the title of the question Stack Overflow has much higher pagerank than the other sites that are mirroring this question under Creative Commons I don't get it.

• Exim redirect all unexisting accounts for local domains to a specific account

  - by tntu

  I want to route all incoming emails for local domains only to a single account if an account is not setup for that user. I would also like each email to be written in it's own file in user folder. I have a catchall user with /home/catchall/ path where I have a mail folder made for this but so far emails wither fail to deliver (thus my rule did not work) or they do deliver to /etc/mail/catchall file. I have been trying to put something together from the Exim configuration but so far nothing seem to work. http://exim.org/exim-html-current/doc/html/spec_html/ch20.html

• How can I have 2 users working on the same PC at the same time

  - by Sharon Cook

  I have a pc/machine that has its own ip address and it can be connected to by certain external PC's through our firewall. User A has a RDP connection from say Germany directly to the PC - his ip number is allowed through our firewall to connect to the PC. He now wants User B to connect at the same time so that User B can see what User A is doing on the screen at the same time and maybe take over the screen to put his input in. I know that you cannot have 2 RDP connections at the same time but what would be the easiest solution to this. I want User A to keep his RDP connection, but I am unsure of what to suggest so that User B can see what is going on at the same time. The Users are not happy to use Real VNC, etc.

• Usage of two Routers on LAN

  - by brusilva

  I've currently own a Linksys E4200 and a Thomson 546v6. Because I have an IPTV service I must set the Thomson as the main router connected to the phone line so that I can distribute the video signal for 2 specific ports and the other two for LAN Access. The problem is that the Thomson doesn't like port forwards, it usually doesnt work and since I have a good router (linksys) currently only working as Access Point I would like to use it as a router itself. I don't want to do a NAT beyond NAT so my question is should I connect the E4200 and to thomson and set the E4200 as a DMZ machine and then control all trafic on the E4200 itself or is there any other option that could suit my needs better?

• networking fails when DNS servers are specified manualy

  - by Matthew Scouten

  When I let Windows-7 use DHCP to find its own DNS server, everything works fine. Then I use ipconfig to get the IPs of the DNS servers in question, and specify them manually. Now the network stops working. (I need to do this because my next step is to restore the router that is going to lie about the proper DNS server. Don't ask why, it is required by my father's work. The IT there are not exactly on the ball.) Why would this make a difference? It is the same set of servers, just obtained differently.

• HALEVT troubleshooting: VFAT usb storage device gets mounted with root:root user:group

  - by Nova deViator

  Hi, i'm banging my head for number of days around this problem. using Halevt for automounting, everything mostly works, but the only thing is that Halevt mounts external USB storage devices as root. So, as user i cannot write to files on them. Halevt gets run as halevt user on boot through /etc/init.d script. This is Ubuntu Lucid with Awesome WM. No GDM. Running halevt as user seem to not work (halevt runs but doesn't respond on Insert) I know HAL is deprecated and removed and i should probably write my own UDEV rules, but until then it seems there must a be simple hack that enables mounting VFAT/NTFS devices with specific uid/gid. this question/answer helps a lot, but not specifically to the above.

• OpenSSH SFTP: chrooted user with access to other chrooted users' files

  - by HannesFostie

  Decided to re-phrase the question entirely in order to not have to make a new one. I currently have an SFTP server set up using OpenSSH's SFTP functionality. All my users are chrooted, and everything works. What I need most right now is for one user, which is not root (because this user can't have any real SSH powers!), to have access to all other users' chrooted dirs. This user's job is to fetch all uploaded documents every once in a while. Directory structure as of now is: /home |_ /home/user1 |_ /home/user2 |_ /home/user3 With ChrootDirectory set as /home/%u User "adminuser" should have access to user1, user2 and user3's directories without having access to /home or at the very least not to anything but /home. Bonus points for the one who can tell me how to let users write inside /home/%u without having to make a new directory inside that dir which they own themselves, and not root as is the case with /home/%u (openssh chroot prerequisite).

• Sabnzbd Installed on Linux NAS

  - by Mike Szp.

  I installed SABnzbd on a linux formatted NAS. Now the directory it downloads to is mapped differently on the NAS itself, because the path that SABnzbd knows about starts in it's own folder. If this sounds confusing let me give you an example: \\MYNAS\Volume_1\ That is the path of the drive on the NAS. I would like my SABnzbd downloads to go to: \\MYNAS\Volume_1\Downloads Right now SABnzbd is installed to: \\MYNAS\Volume_1\ffp\opt\optware\share\SABnzbd And the default download directory (as indicated in SABnzbd is): /ffp/opt/optware/share/SABnzbd/downloads/complete I know that the mapping is different somehow because It is installed on the NAS, but I just am lost as to what I should do. So far, I have tried for the complete folder: /192.168.restofip/Volume_1/downloads/complete /Volumes/Volume_1/downloads/complete /Volume_1/downloads/complete Does anyone know how to change the path so that I can have it download to one of the topmost folders on the NAS instead of having it download to a folder so deep in the drive?

• Move virtual machine hard disk to a separate physical hard disk for better performance?

  - by joeeoj

  I have a dual-core machine with the host OS and many guest virtual OSs. Although I have 8GB of RAM, I notice a slowdown when I turn some virtual machine on (and it takes only 1GB RAM). I was told that I should move virtual machine hard disk file to a separate (another) physical hard drive in my PC to get better performance. This way the head of the hard disk would not have to jump from the virtual OS to the host OS as each hard drive would have its own head to deal with the OS: hard drive 1 head for host OS and hard drive 2 head for guest OS. Is this true? Should I get another hard disk only for virtual machine hard disk files?

• Making LISPs manageable

  - by Andrea

  I am trying to learn Clojure, which seems a good candidate for a successful LISP. I have no problem with the concepts, but now I would like to start actually doing something. Here it comes my problem. As I mainly do web stuff, I have been looking into existing frameworks, database libraries, templating libraries and so on. Often these libraries are heavily based on macros. Now, I like very much the possibility of writing macros to get a simpler syntax than it would be possible otherwise. But it definitely adds another layer of complexity. Let me take an example of a migration in Lobos from a blog post: (defmigration add-posts-table (up [] (create clogdb (table :posts (integer :id :primary-key ) (varchar :title 250) (text :content ) (boolean :status (default false)) (timestamp :created (default (now))) (timestamp :published ) (integer :author [:refer :authors :id] :not-null)))) (down [] (drop (table :posts )))) It is very readable indeed. But it is hard to recognize what the structure is. What does the function timestamp return? Or is it a macro? Having all this freedom of writing my own syntax means that I have to learn other people's syntax for every library I want to use. How can I learn to use these components effectively? Am I supposed to learn each small DSL as a black box?
