  • Greiner-Hormann clipping problem

    - by Belgin
    I have a set of planar polygons in 3D space defined by their vertices in counterclockwise order. Let's define the 'positive face' as being the face of the 3D polygon such as when observed, the vertices appear in counterclockwise order, and the 'negative face', the face which when observed, the vertices appear in clockwise order. I'm doing perspective projection of the set of polygons onto a projection polygon defined by the points in this order: (0, h, 0), (0, 0, 0), (w, 0, 0), and (w, h, 0), where w and h are strictly positive integers. The positive face of this projection polygon is oriented towards positive Z, and the camera point is somewhere at (0, 0, d), where d is a strictly negative number. In order to 'clip' the projected polygons into the projection polygon, I'm applying the Greiner-Hormann (PDF) clipping algorithm, which requires that the clipper and the to-be-clipped polygons be in the same order (i.e. clockwise or counterclockwise). My question is the following: How can I determine whether the projected face of the 3D polygon is the negative or the positive one? Meaning, how do I find out if I have to work with the vertices in normal or inverted order for the algorithm to work? I noticed that only if the 3D polygon is facing the projection polygon with its negative face, both of them are in the same order (counterclockwise), otherwise, a modification needs to be done. Here is a picture (PNG) that illustrates this. Note that the planes described by the polygon from the set and the projection polygon may not always be parallel.

  • back-end SQL server 2005 databases for website

    - by Datapimp23
    Hi, We're migrating an existing IIS website + MS SQL 2005 database (on the same server) to a new test set-up. The existing set-up is too slow. I want one ISS server and 2 X MS SQL server 2005. One live DB server for the website queries (inserts, updates) and another for backups, reports or stored procedures. So the live DB should be more aimed at performance. The other doesn't even need to be synced instantly. What is the best way in SQL server 2005 to set this up. Can somebody point me in the right direction and give me some pointers. Thanks

  • NodeJS Supervisord Hashlib

    - by enedebe
    I have an problem with my NodeJS app. The problem is the include of the library Hashlib I've followed more than 10 times the instructions to install. Get a clone of the repo, do make and make install. NodeJS is installed in default path, and that's the tricky point: When I launch node app.js it works, perfectly. The problem starts when I configured my Supervisord to run with the same user, with the same config file as I have in other systems working, and I get that NodeJS can't find hashlib. module.js:337 throw new Error("Cannot find module '" + request + "'"); ^ Error: Cannot find module 'hashlib' I'm getting crazy, what can I do?! Why my user launching node from the console works great, but not the supervisord? Thanks!

  • Is it possible to retrieve lost Windows XP profile information?

    - by Simon Shaw
    I'm running Windows XP Professional on a PC which is less than a year old. About 3 months ago I got an error on boot saying windows could not find my profile. At this point it created a temp one. On this occasion I copied the temp data back into my existing profile and carried on using it. After another month it died again and, once again set me up a temp user. Each time this happens I lose everything related to my profile (desktop, start menu, etc). I ran checks on the hard disk and these suggested nothing was wrong so this seems a software issue not a disk problem. On the advice of my computer manufacturer I am now considering reinstalling Windows but just wanted to check if there's any other ideas for things I might be able to try. Any suggestions for what could be causing the problem would also be gladly appreciated.

  • Google Blogger Website CName and/or Text File Issues

    - by Francis Gibbons
    I have a blogger Blog website and I would like to have it show up on my company website. I have read a couple articles out there on how to do it. A hand full of them talk about using FTP which is old and no longer available. However, I am trying to following along with this one: http://www.infinite42.com/small-business/integrate-blogger-blog-website Which seems pretty easy but I am having a problem getting Google to Verify the DNS CName or Text Record that I created on my Windows 2007 Server. Do I need to create this record at the registra level. Right now the domain is setup at the registra to point the www record to my server where on my server I tried the Txt Record and the CName Record with no luck in DNS. Here are the Google instructions for creating a CName file record in DNS: Follow the steps below to create a DNS (Domain Name System) record that proves to Google that you own the domain. Add the CNAME record below to the DNS configuration for abc.com. CNAME Label / Host: CNAME Destination / Target: Click Verify below. When Google finds this DNS record, we'll make you a verified owner of the domain. (Note: DNS changes may take some time. If we don't find the record immediately, we'll check for it periodically.) To stay verified, don't remove the DNS record, even after verification succeeds. Here is the link to do it with a CName: http://googlewebmastercentral.blogspot.com/2012/08/domain-verification-using-cname-records.html When I go to add my CName record on my server's DNS the only two fields available are Alias Name and Fully Qualified Domain Name. How am I suppose to create this record can someone please tell me? Thanks, Frank

  • SQL SERVER – What is the Maximum Relational Database Size Supported by Single Instance?

    - by Pinal Dave
    I often get asked following question? “How much data SQL Server can handle?” Every single time when I get this question – I ask back following question - “How much data your storage system can handle?” The reason I ask this question back is because in reality for enterprise systems the limitation of storage is no more an issue. The Matter of the fact most of the database is now a days limited by the size of the storage system. SQL Server is enterprise system and it is very mature product. Even though if you still want to know what is the actual limit here is the answer. SQL Server 2008R2, 2012 and 2014 have maximum capacity of 524 PB (Petabyte) in the Enterprise, BI and Standard edition. SQL Server Express has a limitation of 10 GB due to its nature. I guess, now when you look at my question it will make sense that it is all depending on the size of your storage system. I personally believe at this point of time 524 PB is quite a huge data, but we never know after 10 years when we read this blog post, we all may think what was I thinking actually.

  • How to fix White Screen of Death after updating iTunes?

    - by cust0s
    The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

  • How can I install an Apple Magic Trackpad on a PC without Boot Camp?

    - by rymo
    I have a Apple Magic Trackpad and I'd like to use it with my PC. I have no other Apple hardware besides the Trackpad. I do not have OSX and thus no Boot Camp CD. The Trackpad uses Bluetooth and will pair with Windows 7 without specific drivers (appears as an HID-Compliant Mouse), but all it will do is point and left click (physical click, no touch tap). With Apple's Windows driver update, I should be able to achieve: Tap to click Dragging Drag lock Secondary click Two-finger scrolling Two-finger secondary tap/click But how can I obtain this driver without Boot Camp installed? Apple's Boot Camp update EXE will not install on my PC (non-Apple hardware).

  • Non-Registry Fix for Secondary Mailboxes Sent Items

    - by Jai Kang
    There is a known issue with Outlook and Exchange where "secondary" mailboxes which are mounted in the same profile, e.g. "John Doe" + CorpMailbox1, CorpMailbox2, CorpMailbox3 will place "sent items" from the secondary mailboxes (e.g. CorpMailbox1) in the user's (e.g. "John Doe") Sent Items folder. There is a registry value (something like DelegateSentItems) to semi-fix this, but I'm looking for an Exchange-side solution. It seems like, at some point, an admin made CC rules to fix this, and for the mailboxes where I see a BCC rule: any item sent to [address] BCC to [address]. The behavior "fixes" the issue, but when I duplicate this work-around for new shared mailboxes, the email ends up in the Inbox and not the Sent Items for the shared mailbox. I don't believe there is any outlook/client-side shenanigans going on, as the intended behavior for the older mailboxes works for new PCs/Users (new imagse) without any Outlook Mailbox Rules.

  • Direct DB to Web Server connection

    - by Joel Coel
    I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

  • What can go wrong with a GLIBC upgrade?

    - by Sevenless
    I recently installed a piece of software that my group needs for a research project starting next September. Turns out the software has a known crash bug when used with glibc 2.12.1. My boss asked if we can upgrade glibc on the server that's supposed to run it. Cue my skeptical silence.... At some point, I got it into my brain that messing with glibc was about as good an idea as messing with a hungry puma; however, I've been unable to determine the source of this belief. So, if I go ahead with this: Am I doing something flagrantly stupid (e.g. I won't fix my problem, I will brick my server, or I will initiate a zombie apocalypse)? What can go wrong? What is likely to go wrong? How do I avoid the answers to 2 and 3?

I created a symlink using: ln -s /media/MYDISK /home/camilo/MYDISK chmod 777 /home/camilo/MYDISK I'm setting up smb.conf like this: [myshare1] comment = external disk browsable = yes path = /home/camilo/MYDISK guest ok = yes read only = no create mask = 0775 Also, in the [global] section I tried adding the following lines: follow symlinks = yes wide links = yes unix extensions = no The problem is that when browsing the shared folder in Windows 7, I get a "\\etc\myshare1 is not accessible" error. When pointing the path to a regular folder it works fine. Also, when I point it directly to /media/MYDISK, it shows the same error. EDIT: to make it more interesting, I have no graphical interface, so I need to touch the config files directly..

  • Cloud computing - database loading question

    - by workwise
    Following is the situation, I want to know whether what I want is possible in cloud computing and is it the best way for me: 1) My main site has a Database with tables with millions of rows, and entries are added almost every second. 2) I will setup a mysql mirror, so there will be a backup database always in sync with the main one. 3) There are few tens of thousands of images- growing. So say total size of images few tens of gigabytes. I will be keeping the image data also in sync on the backup server. 4) There can be short periods where traffic can go 100X the average traffic. 5) I will be using memcache heavily - most database and even frequently used disk files/images will be in RAM. I want that the main site runs on a dedicated server. The backup server is say an Amazon EC2 instance. Now note that since it is live backup, I need to run a small instance continuously. I want that when I anticipate high traffic, I should be able to run a large instance on the cloud and transfer the traffic there. The main point is - I do not want to spend time in "loading" the database on the large instance, as it typically can take few minutes or even hours (experience). So is it possible to just scale the memory/CPU on demand, and not having to load the database or sync up the filesystem? I want to setup my backup scripts etc just ONCE. Thanks JP

  • Using a Mac to share a VPN connection

    - by Luis Novo
    I am using an iMac to share a wired network connection with other devices in my house. I am using Apple's built-in sharing functionality which works very well. I have also been using Tunnelblick as an OpenVPN client. The two technologies work great when they are not used together. The moment I connect to my VPN, sharing stops working on all other devices; the whole point of this setup was for me to share my VPN connection. Is there a way to make Internet connection sharing and OpenVPN work together on the Mac? I am using Snow Leopard.

  • Version control and branching when using Oracle

    - by Ed Woodcock
    Hi folks: At work we're using Oracle and C#/ASP.net to handle a customer's website, this site is very large-scale so the database is very large. We use Perforce for our version control, and tack create or replace scripts to FogBugz cases whenever a database change, which has been fine until now, as we are now at a point where five developers are working on five expansions for the system, each on a seperate Perforce branch. Unfortunately, we cannot get duplicate databases, due to the database size, so everyone is still working from the same one. This is obviously a cause of problems: only ten minutes ago we had a bit of an issue where a stored procedure change for a branch propagated over to the Pre-Production server and caused a large number of crashes for the testers. Ideally, we would like a way to track these changes without having to manually keep track of them through FogBugz. My question is: how do you lot handle this situation? I'm sure there must be a good way by now to handle versioning, or at least tracking changes, in an Oracle database.

  • Monitor network connectivity in WP7 apps

    - by Daniel Moth
    Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.

  • How to fetch only the sprites in the player's range of motion for collision testing? (2D, axis aligned sprites)

    - by Twodordan
    I am working on a 2D sprite game for educational purposes. (In case you want to know, it uses WebGl and Javascript) I've implemented movement using the Euler method (and delta time) to keep things simple. Now I'm trying to tackle collisions. The way I wrote things, my game only has rectangular sprites (axis aligned, never rotated) of various/variable sizes. So I need to figure out what I hit and which side of the target sprite I hit (and I'm probably going to use these intersection tests). The old fashioned method seems to be to use tile based grids, to target only a few tiles at a time, but that sounds silly and impractical for my game. (Splitting the whole level into blocks, having each sprite's bounding box fit multiple blocks I might abide. But if the sprites change size and move around, you have to keep changing which tiles they belong to, every frame, it doesn't sound right.) In Flash you can test collision under one point, but it's not efficient to iterate through all the elements on stage each frame. (hence why people use the tile method). Bottom line is, I'm trying to figure out how to test only the elements within the player's range of motion. (I know how to get the range of motion, I have a good idea of how to write a collisionCheck(playerSprite, targetSprite) function. But how do I know which sprites are currently in the player's vicinity to fetch only them?) Please discuss. Cheers!

  • Create 301 Redirection in Amazon Route 53 for Wildcard Subdomains

    - by Eric Yin
    My domain name hosted on Route 53 DNS. Amazon has a guide to do 301 redirection for www. To naked domain by point www. version to a S3 static website with 301 setted up. My question is, how can I have *.domain.com all have 301 redirec to naked domain name. I guess either: Some way to get all wildcard subdomains end up into one S3 bucket, how? Or: Use CloudFront on the www. version S3 site and put wildcard subdomains on the CloudFront, but how? Or: There's some hidden settings just lies on Router 53, then where? Or: use EC2, better not suggest me this, too costing for this task. Please advice.

  • Why does my system use so much cache?

    - by Dave M G
    Previously, on my desktop computer running Ubuntu 14.04, I had 4GB RAM, which I thought should be plenty. However, after being on for a while, my computer would seem to get slow. I have a system resource monitor app in my Gnome panel, which I assume represents the available RAM (?). It shows a dark green area as being "Memory", and a light green area as "Cache". The "Cache" would slowly grow until it filled the whole graph, and then programs would get slow to load, or it would take a while to switch programs. I could alleviate the problem somewhat with this command, but eventually the computer cache fills up again, so it's only a bandaid: sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches" So, I figured I'd get more RAM, so I replaced one 2GB stick with an 8GB stick, and now I have 10 GB ram. And my "cache" still slowly maxes out and my computer slows as a result. Also, sometimes the computer starts out with "cache" maxed when I first boot and log in. Not always though, I don't know if there's a pattern that determines why it happens. Why is Ubuntu using up so much cache? Is 10GB not enough for Ubuntu? Here's what my system monitor looks like in my Gnome panel. The middle square shows RAM usage. The light green area is the "cache": This is my memory and swap history, which doesn't seem to include any information about "cache". I realize at this point I'm not totally clear on the difference between "cache" and "swap":

  • How can I justify software testing to management?

    - by Nate
    I work for a small company (less than 200 employees) whose software group only makes up a small part of our staff (4 employees, occasionally with a few contractors). The four of us have been making strides in transitioning to better practices, and one of the next logical steps is to improve our testing. As anyone who has done any meaningful tests knows, testing takes a lot of time - and at my company, it takes too much time to justify to management, so we generally do what little we do on the sly. I don't think this is serving us well, as we keep coming up against otherwise avoidable problems when we ship under-tested software. I would like to be able to come to management with a justification for hiring a dedicated software test engineer (someone who can both write automated tests and perform manual ones). Are there any good published studies that show the benefits of adding such a position to a small company? Where can I find information about costs associated with the position? I plan on doing a little number crunching on our own history, but having some external sources to point to would help bolster my case.

  • High Availability Configuration using Heartbeat and Pacemaker

    - by pradeepchhetri
    I have the following setup: I have configured high availability between two load balancers (HAProxy) so that if HAProxy1 get down, the floating IP gets transferred to the other load balancer HAProxy2, hence all the clients will get the response from HAProxy2, which at the back-end is doing LB among the sme two webserver. This is for removing the single point of failure in case of only one HAProxy. Whenever I stops the hearbeat in HAProxy1, the floating IP goes to HAProxy2. But I want to configure such that whenever the process haproxy goes down, the floating IP should get assigned to HAProxy2. Can someone tell me how to implement it ?
