• Setting effects variables in XNA

  - by Badescu Alexandru

  Hello ! I am currently reading a book named "3D Graphics with XNA Game Studio 4.0" by Sean James and have some questions to ask : If i create a effect parameter named lets say SpecularPower and have in my effect a variable named SpecularPower , if i do something like effect.Parameters["SpecularPower"].SetValue(3) That wil change the SpecularPower variable in my effect ? And a second question, not regarding the book : If i have a spaceship and i've created a "boost" functionality that speeds up my spaceship, what effects should i implement to create the impresion oh high speed ? I was thinking of making everything except my spaceship blurry but i think there would be something missing . Any ideas ? Regards, Alex Badescu

• How to safely collect bank account from website?

  - by Alexandru Trandafir Catalin

  I want to collect bank account information from my customers on my website. I'd like to do that trough a form, then I will download it to a PC, print it, and then delete it from the website. Or eventually, send it somewhere external right after the user submitted the form so it never gets stored on the website. The goal is to recieve the payment information without having to ask the customer to print, fill manually, and send it over fax. And accomplish this without having to use an external payment gateway. Thank you, Alex.

• Smartassembly 5: it lives! Early Access builds now available

  - by Bart Read

  I'm pleased to announce that, late last week, we put out the first early access build for Smartassembly 5, Red Gate's fantastic code protection and error reporting tool, which we acquired last September. You can download it via: http://www.red-gate.com/messageboard/viewforum.php?f=116 It's obviously pretty early days, so please do not try to use this to protect a production application, but we've already done a lot of work in some key areas: We're simplifying and streamlining the licensing model (you won't see this yet, but a lot of the work on this has already been done). We've improved usability of the product, with a better menu, reordering of project settings, and better defaults. We've also fixed a load of bugs, which I'll let Alex blog about in more detail. On a slightly more trivial level, the curly braces are also no more. Over the coming weeks, we'll be adding more improvements, and starting usability tests. If you're interested in getting involved in the latter, please drop an email to [email protected].

• Split a text file by its entries

  - by Alexx Hardt

  Hi, I'm trying to analyze an enormous text file (1.6GB), whose data lines look like this: 20090118025859 -2.400000 78.100000 1023.200000 0.000000 20090118025900 -2.500000 78.100000 1023.200000 0.000000 20090118025901 -2.400000 78.100000 1023.200000 0.000000 I don't even know how many lines there are. But I'm trying to split the file by date. The left number is a time stamp (these lines are from 2009, January 18th). How can I split this file into pieces according to the date? Everything I know would be to grep file '20090118*' > data20090118.dat , but there sure is a way to do all the dates at once, right? The number of entries per date differ, so using split with a constant number won't work. Thanks in advance, Alex

• Les développeurs détestent-ils les antivirus ? Un programmeur manifeste sa haine envers ces solutions de sécurité

  Les développeurs détestent-ils les antivirus ? Un programmeur manifeste sa haine envers ces solutions de sécurité « Je déteste les antivirus ». C'est par ces mots que Alex Yumashev, un développeur .NET révèle dans un billet de blog pourquoi il déteste les antivirus. Ces logiciels dont la mission principale est l'identification, la neutralisation et la suppression des programmes malveillants sont quelques fois des sources de problèmes pour les développeurs lors des tests ou de l'utilisation de leurs applications qui sont identifiées comme des menaces. Ymashev explique que malgré la signature de son application avec un certificat de confiance Verisign, malgré qu'elle ait été ...

• Behavior tree implementation details

  - by angryInsomniac

  I have been looking around for implementation details of behavior trees, the best descriptions I found were by Alex Champarand and some of Damian Isla's talk about AI in Halo 2 (the video of which is locked up in the GDC vault sadly). However, both descriptions fall short of helping one actually create a BT, one particular question has been bugging me for a while. When is the tree in a behavior tree evaluated? Furthermore: If the tree is in the middle of executing a sequence of actions (patrolling waypoints) and a higher priority impulse comes in (distraction sound) , how to switch to that side of the tree seamlessly without resorting to a state machine like system and if it is decided that the impulse was irrelevant (the distraction is too far away to affect this guard), how to go back to the last thing that the guard was doing ? I have quite a few questions like this and I don't wish to flood the board with separate queries so if you know of any resource where questions like these can be answered I would be very grateful.

• Dependency problem while missing package is already installed

  - by hakermania

  I am trying to install a program but I am getting a dependency error. The error clearly points out: Dependency is not satisfiable: libc6-amd64 (>= 2.14) I went on to investigate and I found out that I have 2.19 version installed, actually: alex@MaD-pc:~$ apt-cache policy libc6-amd64 libc6-amd64:i386: Installed: 2.19-0ubuntu6 Candidate: 2.19-0ubuntu6 Version table: *** 2.19-0ubuntu6 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main i386 Packages 100 /var/lib/dpkg/status Why am I getting this error if I already have this package? I also should probably mention that the system is 100% up to date. I run the updates and upgrades, restarted the system and then tried to install the package again with the same error popping up. Edit 1: I am using amd64 but I have installed some 32-bit libraries required by some program installed via wine if I recall correctly.

• Contiguous Time Periods

  It is always more efficient to maintain referential integrity by using constraints rather than triggers. Sometimes it isn't obvious how to do this. Until a recent idea by Alex Kuznetsov, the history table presented problems for checking data that were difficult to solve with constraints. Joe Celko explains.

• Cannot add folders to Ubuntu One

  - by Akmur

  I have signed up with Ubuntu One (20GB) and I'm having the following issue: I basically cannot add folders through the panel interface. I have been able to add five folders so far, but I'd like to add some more (yes, they are inside the home folder). I don't get no errors, but nothing is added to the folders list. By using the command line interface like this u1sdtool --create-folder /home/alex/Web it basically hangs. Nothing happens. If I then list the folders with command line, my folder is not there. Any idea? (I'm on 12.10)

• Question about whether I should pursue minors or work towards a masters [closed]

  - by user75493

  I'm a sophomore about to go into my Spring semester in a few weeks and I am trying to decide some major things that will affect the next few years of my life and was looking for some guidance/advice. I'm currently working towards a Bachelors in Computer Science and my question was whether I should minor in Corporate Strategy and Math or just work towards a Masters in Computer Science? I was wondering if employers are more looking for Masters degrees in Computer Science or if those minors could be beneficial to me. Some things that may affect responses: I already have all my other requirements filled for graduating except my Computer Science classes, I've already had an internship this past summer and am already hearing back from several companies about internships for this upcoming summer. Thanks in advance! - Alex

• A relatively new blog seems to be getting very poor Google indexing

  - by Genadinik

  I have a new blog that is 2 months old. In the first few weeks, it was getting indexed nicely and my GoogleWebmaster reports were showing that it was getting crawled and began ranking for some terms. Then as I kept writing, the GoogleWebmaster report thinned out and showed less and less terms that this blog ranks for. Now there are only 4 terms with one of them being my name. Is there something I need to do to keep the old posts to remain indexed and crawled? Thanks, Alex

• SQL Performance Problem IA64

  - by Vendoran

  We’ve got a performance problem in production. QA and DEV environments are 2 instances on the same physical server: Windows 2003 Enterprise SP2, 32 GB RAM, 1 Quad 3.5 GHz Intel Xeon X5270 (4 cores x64), SQL 2005 SP3 (9.0.4262), SAN Drives Prod: Windows 2003 Datacenter SP2, 64 GB RAM, 4 Dual Core 1.6 GHz Intel Family 80000002, Model 6 Itanium (8 cores IA64), SQL 2005 SP3 (9.0.4262), SAN Drives, Veritas Cluster I am seeing excessive Signal Wait Percentages ( 250%) and Page Reads /s (50) and Page Writes /s (25) are both high occasionally. I did test this query on both QA and PROD and it has the same execution plan and even the same stats: SELECT top 40000000 * INTO dbo.tmp_tbl FROM dbo.tbl GO Scan count 1, logical reads 429564, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. As you can see it’s just logical reads, however: QA: 0:48 Prod: 2:18 So It seems like a processor related issue, however I’m not sure where to go next, any ideas? Thanks, Aaron

• Cisco IOS PBR - PBRing Skype

  - by Azz

  I've got a very simple question, which seems to be extremely difficult when put into practice. I have a Cisco IOS router with two Internet links (one over a WAN, through a proxy, everywhere, etc.) the other direct Internet. Most traffic destined for the internet goes through the proxy over the WAN. I want Skype traffic (why the client uses skype, I don't know..) to go out of the Internet link, while the rest of the traffic goes over the WAN through the proxy, etc. Apparently skype is very difficult to detect/classify because of it's many adaptations to being blocked. Is there any way to identify Skype on an IOS router (2911), and set it's next hop IP/interface? Thank you, Aaron

• What ports does Advantage Database Server need?

  - by asherber

  I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \\server, and it's listening on port 1234. When \\client tries to connect to \\server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \\server:1234\tables, I get error 6097, bad IP address specified in the connection path. \\server is pingable from \\client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron. Edit: I should have specified that the firewall is open to \\server:1234 specifically for TCP traffic. Is UDP involved here in some way?

• powershell run java process problem

  - by Limited Atonement

  Dear Sirs, I'm trying to run a java process via Powershell in Windows XP. Here's the command: java.exe -cp .;./common.jar -Dcontext=atest1 -Dresourcepath=. DW_Install So, the classpath is . and .\common.jar (I think java takes the wrong slashes, right?) There are two environment variables, one "atest1" the other "." and the class to execute main on is DW_Install (in the default package). This command works in cmd.exe, but doesn't is PS. What's going on? What is PS doing while parsing this command that CMD doesn't do (or vice versa)? Aaron
