• Hardware-specific questions

  - by overflow

  I'm good at programming yet I feel like I don't know enough about the architecture of the hardware I'm working on. What does the Northbridge on the mainboard do? What does the L2 cache of my processor do? Can Windows XP use multiple processors? Not in terms of concrete multitasking in all programs but using the capacity of all cores if needed instead of always only one core. How can my processor/mainboard interact with multiple kinds of graphics/sound cards?

• CSS Overflow issue in IE7

  - by BrynJ

  I'm working on a site for a client at the moment, and have it working correctly in all browsers except IE7 (IE6 and IE8 tested fine). It's a WordPress site and the theme is a child theme of the Thematic framework. This is an example of a page that is not displayed correctly in IE7: http://roynesbitt.credit-medics.co.uk/our-donors The main content is forcing vertical and horizontal scrollbars on the main wrapper and is also not pushing the footer down, so that is appearing midway through it. The irony is that this works correctly in IE6, it's just IE7 that is displaying this issue. Any suggestions on how to fix are gratefully received.

• Conditionally embed ASP.NET MVC2 Views as resources during build in Visual Studio 2010

  - by jslatts

  I have a ASP.NET MVC2 project in VS2010 that can be deployed in two modes: standalone or plugin. In standalone mode, the views should live outside the compiled assembly as .aspx files (the default setup). In plugin mode, the views are switched (currently by hand) to embedded resources and the entire assembly is dropped into a host project folder. Currently, this requires the developer to go through each view and switch it from Build Action: "Content" to "Embedded Resource" and vice versa. I would like to create a new solution configuration to automatically grab all .aspx files and build them as resources. This SO post seems like the solution, but I would prefer not to have to edit the .csproj every single time I add a new view to the project. Is there a way to use a wild cards or some other batch/global conditionally statement to change resources from content to embedded?

• Stopping pirates

  - by Pirate for Profit

  Okay, what do I do to stop pirates? Obviously a callhome to internet service. We are considering making some major aspects be dependent on a web service of some sort. Memory offsets and cracking. If I like rand randomly to allocate empty memory on the heap, would this throw off the crackers? I hacked some memory shit for EverQuest back in the dizzay but don't really know much about this. Registry on windows, etc., I know theres ways to identify the computer. That's easily spoofed with hex editor, but if I jumble up the strings in the program would that help? I need to know that + real ideas. I want the serials of their sound cards. Any other ideas?

• Reject (Hard 404) ASP.NET MVC-style URLs

  - by James D

  Hi, ASP.NET MVC web app that exposes "friendly" URLs: http://somesite.com/friendlyurl ...which are rewritten (not redirected) to ASP.NET MVC-style URLs under the hood: http://somesite.com/Controller/Action The user never actually sees any ASP.NET MVC style URLS. If he requests one, we hard 404 it. ASP.NET MVC is (in this app) an implementation detail, not a fundamental interface. My question: how do you examine an arbitrary incoming URL and determine whether or not that URL matches a defined ASP.NET MVC path? For extra credit: how do you do it from inside an ASP.NET-style IHttpModule, where you're getting invoked upstream from the ASP.NET MVC runtime? Thanks!

• Repeating a List in Scala

  - by Ralph

  I am a Scala noob. I have decided to write a spider solitaire solver as a first exercise to learn the language and functional programming in general. I would like to generate a randomly shuffled deck of cards containing 1, 2, or 4 suits. Here is what I came up with: val numberOfSuits = 1 (List["clubs", "diamonds", "hearts", "spades"].take(numberOfSuits) * 4).take(4) which should return List["clubs", "clubs", "clubs", "clubs"] List["clubs", "diamonds", "clubs", "diamonds"] List["clubs", "diamonds", "hearts", "spades"] depending on the value of numberOfSuits, except there is no List "multiply" operation that I can find. Did I miss it? Is there a better way to generate the complete deck before shuffling? BTW, I plan on using an Enumeration for the suits, but it was easier to type my question with strings. I will take the List generated above and using a for comprehension, iterate over the suits and a similar List of card "ranks" to generate a complete deck.

• Where can I learn about security and online privacy?

  - by user278457

  I'd really like to start including shopping cart functionality in my projects. At first im content relying on paypal links, but I really want to be learning about specific security threats and how to combat them. Eventually I want to feel comfortable receiving and sending customer credit card details for ecommerce. Obviously this is a common thing on the net but most tutorials and resources are content to say "it's every web developers responsibility to consider security, but we're not going to cover that here/today/ever." so, my question is, where is a good place to learn? And once I've learned, how do I stay abreast of new vulnerabilities as the web evolves?

• How can I retrieve monitor information?

  - by Jon Tackabury

  I am trying to retrieve the monitor ID's as shown in the Windows display properties (#1, 2... etc), but I can't seem to find a way. I have tried using EnumDisplayMonitors as well as EnumDisplayDevices. They both return something like "\.\DISPLAY1". However, this number doesn't always match the number shown by Windows, especially when 2 video cards are being used to drive 3 or more monitors. Is there an API call I am missing to retrieve this information, or is there a way to get it from the registry or somewhere else? Thanks! I have tried these methods: Win32: EnumDisplayMonitors, EnumDisplayDevices: Neither of these return monitors that aren't active, and neither one returns the correct IDs. WMI: "select * from Win32_DesktopMonitor" doesn't return all the monitors, and there is no ID. Registry: I have found the monitors in various locations, none of the places I found have the info I am looking for. Any help is much appreciated. :)

• Facebook insights for websites does not match on-site Facebook button counts

  - by Will

  I use Facebook Insights for websites and Facebook buttons on my site. However, the data reported by the two do not match. It always seems to be the case that the count reported by the buttons is significantly higher than the count reported in Facebook Insights. For example, this page http://www.appmyworld.com/blog/top-5-iphone-and-ipad-apps-of-the-week-10412.html has a count of 52 for Facebook which is made up of 19 likes, 21 shares and 12 comments according to AddThis and confirmed by http://sharedcount.com However, going into Facebook Insights for my website and looking at that specific page it shows only 4 total actions which is made up of 1 like and 3 shares. At the very least I would expect it to show a total count of 40 made up of 19 likes and 21 shares (I'm not sure it would track the 12 comments). Any thoughts on why this may be happening? My concern is if our website is not getting credit for the Facebook activity?

• Cheapest way to go for somebody who wants to accept payments, but won't be accepting hundreds of ord

  - by blockhead

  I have a client who lectures, and wants to sell spots to his lecture online. I would preferably like to set him up with a solution that allows me to collect billing information on his site. My experience with e-commerce is in using solutions like Authorize.net, however this does not seem cost effective since I can't imagine he's making a huge profit off of this. I'm afraid he would lose money in the cost of using Authorize.net (or any payment gateway for the matter). I could use google checkout or paypal express, but this would require me to leave his site (although with google checkout, it looks like, from a glance, that I could just submit to their form from my server, and likely with paypal as well, but I don't know if this is against their TOS). What is the most cost-effective solution for accepting credit card payments in this situation?

• Django remove list_editable on a per row basis.

  - by Jason Leveille

  On the back of Django 1.2RC1, I have built a great administrator for my client! It's awesome. The client has one request that, if not satisfied, could bring this house of cards crashing down. I have a list of swim meet results. A meet result is added by a superuser. A team rep can edit a meet result (which they must be able to do inline, with list_editable), but after they edit the meet result inline and save, they should no longer be able to edit that result inline. They can only perform one edit. So, my question ... can I turn off list_editable on a per row basis?

• Multiple Payment options within the same order

  - by Rob Y

  I have a requirement to be able to accept different forms of payment within the same order - ie not just the usual credit card or paypal for the whole thing, but perhaps paypal for one item, cheque for another. I know this sounds quite crazy, but there is a good business reason for the requirement so I can't just push back. The best way I can think of implementing it at the moment is to have kind of a hub page, where you can "launch off" into multiple flows for each of the payments by opening new windows. I can't figure out a way of doing this in a linear flow as for example you can't guarantee that a user will come back from paypal, so you'd then lose the user completely. Is there a neater way of doing this that anyone can think of, or can anyone point me to an example of a site that does somethign similar for inspiration?

• Problems with IRQs when connecting two digium card in and asterisk box

  - by JorgeO

  I have two Digium Wildcard TDM800P with 8 FXO ports each. When I connect both at the same time IRQ misses start showing up making my computer unresponsive and unusable. One card works fine but I need all 16 FXO ports to work to receive calls from my Telco. Is there a way for the cards to communicate with each other so they don't generate as many interrupts. Or a way to tweak Linux to dedicate separate IRQ's for each card. I have tried disabling Audio, ACPI and USB ports. Still too many IRQ misses.

• How to go about with real GUI development with Java Swing and MVC.

  - by Myth17

  I am creating a Blackjack Card game emulator. I am a SCJP,familiar with Core Java concepts. I have a very basic understanding of Java swings and awt. Already finished writing the basic game logic,a CLI logic. My design includes several classes like, Dealer,Player,Table,Card,Casino and some others.. Enums for Cards and suite. I have read about MVC as a theoretical concept, familiar with the name 'design patters'(no understanding whatsoever as to how they are implemented) Everywhere I am suggested to learn while writing some real code.So I started off with this... I am stuck now, how should I go about writing code for my project?? Writing the GUI code and organising it within the already existent code.

• How to get data from another page (different servers)

  - by rjovic

  I want to make a IE8 web slice who will show remaining amount of students "food credit". In our country we have web page where we can see ammount www.cap.srce.hr/ProvjeraSaldo.aspx. When I fill textbox with my card number i recieve remaining amount. Now, i want to speed that process with ie8 web slice. So is it possible to get data from another webserver page and than display it in my web slice on my web server. I tried to use XMLHTTP request but it can be only used on same domains. Url for getting amount is : http://www.cap.srce.hr/saldo.aspx?brk={number_of_card}

• OpenGL - lighting of vertices outside clip range

  - by hmp

  I have a problem with lighting in my OpenGL application. When one of the vertices of a drawn polygon goes outside the front clip plane (or has z<0, I'm not sure which), the polygon stops being lighted properly. This however happens on only one machine I tested, with Intel GMA950 card. On nVidia and ATI cards everything looks fine. I guess I am breaking some OpenGL rule here? How should I deal with it? I'd try dividing the scene into smaller polygons, but I'm not sure if it guarantees the case is eliminated (all polygons stepping outside the clipping range are offscreen).

• To be a lazy developer or not to be a lazy developer?

  - by JamesStuddart

  Am I a lazy developer? Is it being lazy to use automated tools, such as code generators and such? Now, I could, if I had to, create all the data layers and entities I needed, but I choose to use CodeSmith to generate my datalayers and entities. I also use Resharper and I would say it fights with MSDeploy as to which gets installed first after Visual Studio. Again if I had to, I could code without it, but prefer not to. Both these tools from my point of view are no brainers as they improve output massively. But is this lazy? I'm sure there are purists out there that would say everything should be wirtten by you so you know what everything is doing, but if you can read through the code and see what is happening is that ok? So am I being lazy or am I just using all the cards in my hand?

• desktop module for existing web application

  - by maxxxee

  My client has a running web application which has been online for more than a year. Recently the client has introduced smart cards for his employees. Because of the difficulty in integrating smart card with its api on a web interface(i will post another detailed question on this later) we are planning to have desktop interface for this. There are 10-20 terminals which will use the desktop interface. 3 approaches for doing this that I have considered : Direct connection and operations on DB-Not using this because of data integrity and consistency issues. Build web service end points and use it from desktop interface Build a dll with common functions and use from both web and desktop Questions: 1. What are your opinions based on 2 and 3 approach? 2. Any other approach that I should consider? Note: I am using .Net framework, web application in asp.net

• ReportViewr: Hyperlink to a local file doesn't work

  - by kernelMode

  I need to add 2 type of links to existing report with c#. For exapmle: 1) http://www.google.co.il/ 2) file:///C:/index.html I added the links, but only the "http://" works. when I press the link of "file:///" nothing happens. I've uploaded the full project (very small though) which includes the problem: http://www.filefactory.com/file/452gsoyymalv/n/ObjectReports.zip btw, The "index.html" is a simple 'helloWorld' which loaded successfully when writing the path on the address bar in the browser. Do anyone know what additional settings should be set to make the link work? Thanks!!!

• PostgreSQL: keep a certain number of records in a table

  - by Alexander Farber

  Hello, I have an SQL-table holding the last hands received by a player in card game. The hand is represented by an integer (32 bits == 32 cards): create table pref_hand ( id varchar(32) references pref_users, hand integer not NULL check (hand > 0), stamp timestamp default current_timestamp ); As the players are playing constantly and that data isn't important (just a gimmick to be displayed at player profile pages) and I don't want my database to grow too quickly, I'd like to keep only up to 10 records per player id. So I'm trying to declare this PL/PgSQL procedure: create or replace function pref_update_game(_id varchar, _hand integer) returns void as $BODY$ begin delete from pref_hand offset 10 where id=_id order by stamp; insert into pref_hand (id, hand) values (_id, _hand); end; $BODY$ language plpgsql; but unfortunately this fails with: ERROR: syntax error at or near "offset" because delete doesn't support offset. Does anybody please have a better idea here? Thank you! Alex

• addChild in the same layer

  - by CEAFDC

  I'm doing an application that puts tons of sprites on the screen in random position, like throwing cards on a table, but after a while it starts to drop the fps, because all the sprites still there. What I would like to do is adding the sprites but like an image, what's behind isn't stored. There are some way to do that? the code looks like this: var mySprite:MySprite = new MySprite(); mySprite.x = random; mySprite.y = random; mySprite.rotation = random; addChild(mySprite); Ps: I will not have to mess with them after they are on the screen.

• Tomcat startup fails with not a valid identifier

  - by Nigel

  I have tomcat 6.0.18 running on one server without a problem. With the exact same settings it fails to launch on my colleague's machine. He's even running from the same folder as me (I've stopped my copy while he tries to make it work) All we get when we fire off tomcat using bin/startup.sh is this: CATALINA_OPTS=-server -Xms768m -XX:+UseParallelGC -Xmx768m -XX:MaxPermSize=256m -XX:PermSize=128m -Djava.awt.headless=true: is not an identifier I had that definition in setenv.sh and moved it into startup.sh - same problem. Any suggestions? My brief look on google seem to indicate multiple IP address issues, but my server has two ethernet cards, and two IP addresses. Thanks.

• UML and Documenting Simple Diagrams

  - by Jason

  As part of a rewrite of an old Java application into C#, I'm writing an actual Software Design Specification. A problem I run into is when a method is too simple to bother with a Sequence Diagram (it doesn't interact with other objects). As an example, I have a simple POJO called Item, containing the following method: public String getCategoryKey() { StringBuffer value = new StringBuffer("s-"); value.append(this.getModelID()); value.append("-c"); return value; } The purpose and the algorithm for the method needs to be documented. However, a sequence diagram is overkill. How would others document it? (I take no credit/blame for the given method, it's very old code and the author "forgot" to put their name in the Javadoc).

• MonoDevelop in Linux -- Terminal Commands

  Hi everyone, I want to make a C# app in Mono as it's the only programming language I'm mostly comfortable with. Anyway, ATI Drivers on Linux do not have a Fan control feature and therefore the cards to tend to heat up. For me I prefer to have a cooler card. What I want to do is run a command such as: aticonfig --pplib-cmd 'set fanspeed 0 70' In a application but I the thing is..How can I run that code so it works, I am currently running Ubuntu 10.04, and it does work in the terminal, but I want to implement it into an application. Thanks
