• Animate 3D model programmatically-where to start?

  - by amile

  I am having a task to create a 3D model face that can talk like humans.without having any knowledge about 3D modeling. I have no clue where to start.I have searched a lot and find some of these things.OpenGL,WebGL,XNA and other similar tool can be helpful. please guide me where to start a step by step approach and which platform is better as i have programming background in JAVA. here is an idea what I need to do https://docs.google.com/viewer?a=v&pid=gmail&attid=0.2&thid=13f65486a46a1f67&mt=application/pdf&url=https://mail.google.com/mail/?ui%3D2%26ik%3D49f1f393c6%26view%3Datt%26th%3D13f65486a46a1f67%26attid%3D0.2%26disp%3Dsafe%26realattid%3Df_hi6ylzbv2%26zw&sig=AHIEtbQc8KQNHdprmEnL4UXyD3ox8vlKKQ

• c# Delegates, Events and Lambda Expr for new students

  - by MarkP

  I've been asked by my pointy haired boss to educate our new co-ops (interns) in the ways of C#. I have roughly ~30mins to cover the topics of Delegates, Events and Lambda Expressions. The time restriction is rather tight and the topics are broad. Since I'm not a C# guru, I would like some hints and pointers. Since my time is short, what points should I cover with respect to the three topics listed above? What are some good Do's and Dont's when using those three things? I might have time for a short Lambda Expr demo. What is the most common use of LExpr (probably a Select().Where() statement on an enumerable??) that I could demo? Thanks. EDIT: The students have working knowledge of C++ and Java.

• Is there a library / tool to query MySQL data files (MyISAM / InnoDB) without the server? (the SQLit

  - by MGW

  Oftentimes I want to query my MySQL data directly without a server running or without having access to the server (but having read / write rights to the files). Is there a tool or maybe even a library around to query MySQL data files like it is possible with SQLite? I'm specifically looking for InnoDB and MyISAM support. Performance is not a factor. I don't have any knowledge about MySQL internals, but I presume it should be possible to do and not too hard to get the specific code out? Thank you for any suggestions!

• Is it possible to use JavaScript to break the HTML of a page?

  - by Karl Brown

  I've been asked at work whether it is possible to write, on purpose or by accident, JavaScript that will remove specific characters from a HTML document and thus break the HTML. An example would be adding some JavaScript that removes the < symbol in the page. I've tried searching online and I know JavaScript can replace strings, but my knowledge of the language is negligible. I've been asked to look into it as a way of hopefully addressing why a site I work on needs to have controls over who can add bespoke functionality to the page. I'm hoping it's not possible but would be grateful for the peace of mind!

• What advantages can I get from learning C++ if I'm mainly a C# Programmer?

  - by Sergio Tapia

  Hello, Recently I've started to notice a lot of smirks and generally rude comments whenever I mention C#. Everyone I talk to either says learn Python or learn C++. Python is a nice language, I get it. But I don't find much use for it right now (for my use cases), and C++ I heard is a faster language (not sure). So my question is this, what advantage can I get from learning C++ (besides the knowledge and expansion of my horizons), when I mainly program in C#. If anyone can make a legitimate claim, I'll for sure look into learning the language because let's face it, I trust you guys. Thanks so much for all the help.

• VST plugin : using FFT on audio input buffer with arbitrary size, how ?

  - by Led

  I'm getting interested in programming a VST plugin, and I have a basic knowledge of audio dsp's and FFT's. I'd like to use VST.Net, and I'm wondering how to implement an FFT-based effect. The process-code looks like public override void Process(VstAudioBuffer[] inChannels, VstAudioBuffer[] outChannels) If I'm correct, normally the FFT would be applied on the input, some processing would be done on the FFT'd data, and then an inverse-FFT would create the processed soundbuffer. But since the FFT works on a specified buffersize that will most probably be different then the (arbitrary) amount of input/output-samples, how would you handle this ?

• How to programatically create and read WEP/EAP WiFi configurations in Android?

  - by Als

  How to programatically create and read WEP/EAP WiFi configurations in Android? I have seen a number of people struggling on this very question on various forums and all across the community. I know this is not that straight forward(especially EAP) to figure out because When I wanted to acheive the same I too struggled quite a lot.Well, all the hard work of code analysis and searching various implementations on the internet done with I was finally able to acheive the goal. All the credit goes to number of open source projects and their developers. I would like to share this knowledge with all, Since SO encourages this: "It's also perfectly fine to ask and answer your own question, as long as you pretend you're on Jeopardy: phrase it in the form of a question." Part 1: Creating a WEP WiFi configuration programatically. Part 2: Read a WEP WiFi configuration programatically. Part 3: Read a EAP WiFi Configuration programatically. Part 4: Save a EAP WiFi configuration programatically.

• How to see contents of deployed datasource?

  - by callisto

  I've inherited a project (without a handy handover) that contains reports published to a Reporting Server (2005). MY SSRS knowledge is 4 years stale, so I need your help. I need to edit one of the published reports, is this possible? I also want to peek into the Data Source on the RS, coz that's probably where I can change stuff. I'll add more info as I get a better understanding of what exactly to ask. EDIT: I found a project for some of the reports, opened up in VS2005 BI. Still, how do see where the Data Source gets its data? It brins back 56 fields but I dont know which tables/stored procs/queries are used to get these.

• Why is this postgresql query so slow?

  - by user315975

  I'm no database expert, but I have enough knowledge to get myself into trouble, as is the case here. This query SELECT DISTINCT p.* FROM points p, areas a, contacts c WHERE ( p.latitude > 43.6511659465 AND p.latitude < 43.6711659465 AND p.longitude > -79.4677941889 AND p.longitude < -79.4477941889) AND p.resource_type = 'Contact' AND c.user_id = 6 is extremely slow. The points table has fewer than 2000 records, but it takes about 8 seconds to execute. There are indexes on the latitude and longitude columns. Removing the clause concering the resource_type and user_id make no difference. The latitude and longitude fields are both formatted as number(15,10) -- I need the precision for some calculations. There are many, many other queries in this project where points are compared, but no execution time problems. What's going on?

• Why is there no Microsoft Certified Master program targetted at developers?

  - by Jason Coyne

  In the lower level certifications, developer technology is all over the place. At the highest level (Microsoft Certified Architect), the Solutions track appears to be a good fit for high level application designers and architects. MCA requires an MCM as a prerequisite. However, none of the MCM tracks are targeted towards development. Obviously to be a good architect you need to have knowledge of other technologies, servers, sql, messaging etc. But those seem like things that should be part of the course load, and not the sole focus. Are the lower tiers really as high as you can go for application focused professionals? For most developers, the SQL MCM seems to be the best fit. Are the MCM and MCA really targeted ad more administrators and not developers?

• Commercial CMS on Google App Engine, violation of terms?

  - by Yaggo

  I'm developing commercial CMS running on Google App Engine. I'm thinking of selling it in two ways: 1) Software as a service (SaS). The CMS running in my App Engine account (as single app), hosting the sites of all customers. A turn-key solution for "end user" customers. 2) Licence for running the CMS in customer's own App Engine account. Targeted for digital agencies for reselling as SaS. Being not a lawyer myself, I don't trust my abilities to read between the lines of TOS jargon. Counting on the general knowledge of SO community, my question is: do the above scenarios violate the App Engine Terms of Service?

• Find value within a range in lookup table

  - by francis

  I have the simplest problem to implement, but so far I have not been able to get my head around a solution in Python. I have built a table that looks similar to this one: 501 - ASIA 1262 - EUROPE 3389 - LATAM 5409 - US I will test a certain value to see if it falls within these ranges, 389 -> ASIA, 1300 -> LATAM, 5400 -> US. A value greater than 5409 should not return a lookup value. I normally have a one to one match, and would implement a dictionary for the lookup. But in this case I have to consider these ranges, and I am not seeing my way out of the problem. Maybe without providing the whole solution, could you provide some comments that would help me look in the right direction? It is very similar to a vlookup in a spreadsheet. I would describe my Python knowledge as somewhere in between basic to intermediate. Many thanks in advance.

• What are the likely main reasons my website is very slow on IE?

  - by Bhupi

  Hi, I need to know what can be the main reasons (apart from the basics like grouping CSS selectors, reducing image size, using image sprite etc.) which makes a website slow on Internet Explorer, because my website works fine on the others like FF, chrome etc. Is it the huge use of Javascript framework (ie. jQuery, extjs, prototype)? Is it because of the use of plugins based on JS framework? Should I use core javascript and remove the use of any js framework? Should I try to avoid using jQuery(document).ready()? in case of jQuery framework? Above some of the questions which I know and please answer the questions which I couldn't ask because of lesser knowledge about these. I need to make my website perform well on IE (6,7,8) also please suggest. Thanks

• C# Dynamic Query Without A Database Model

  - by hitopp

  I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

• Would you make this method Static or not?

  - by Adam Drummond

  During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing. So I did quite a bit of research and obviously it's a specialized case but I would like to know what you would do in this situation and why? (Its basically a helper method I call from a few different methods, a very low traffic page. More for my knowledge and learning on Static.) private IEnumerable<Category> GetCategoryByID(int id, Context context) { var categoryQuery = from selectAllProc in context.SelectAll_sp() where selectAllProc.CategoryID == id select selectAllProc; return categoryQuery; }

• Template approach for a PHP application

  - by Industrial

  Hi everyone, We're in the middle of making a new e-commerce related PHP application and we have come to the point where we have started to think about how we should solve templating for our customers needs. What we would like to do is offer our customers the possibility of uploading/modifying templates to suit their company:s profile. The initial thought is that we shall not reinvent the wheel, so instead letting our customers upload their templates with FTP, so there will be basic HTML skills required. For those customers that want to modify/customize template and doesnt have the knowledge, we offer that service as well. I know that there's a number of issues to solve before this could be considered safe, like preventing XSS and writing scripts that check through each uploaded file for potential security threats and so on. Of course, there are some part that probably will be to complex for the customer to modify by themselves, so maybe this approach won't apply to all<< template files in the frontend application. But besides that, what would be a good way to handle this?

• Can I use a single MySQL query to select distinct rows and then non-distinct rows if a limit hasn't

  - by Matt Rix

  I hope I'm explaining this properly, my knowledge of MySQL is quite limited. Let's say I have a table with rows that have name and shape fields. I'd like to select a bunch of rows from a table, but return all of the rows with unique shape field values first. If I have less than a certain number of rows, let's say 7, then I'd like to fill the remaining result rows with non-unique shape rows. The best way I can word it is that they're "ordered by uniqueness, and then by some other value". So, I don't want: square, square, circle, circle, rectangle, square, triangle I'd like to have: square, circle, rectangle, triangle, square, square, circle Is this possible to do using a single SQL query? I'm using MySQL with PHP, if that makes any difference. Thanks!

• Does anybody have practice in programming PCMEF - architectures?

  - by Erkki

  PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

• text watermark on website? how to do it?

  - by Tim

  I am a C++/C# developer and never spent time working on web pages. I would like to put text (randomly and diagonally perhaps) in large letters across the background of some pages. I want to be able to read the foreground text and also be able to read the "watermark". I understand that is probably more of a function of color selection. I have been unsuccessful in my attempts to do what I want. I would imagine this to be very simple for someone with the web design tools or html knowledge. Any links or sample code? Thanks

• Security in HTTP Adapters

  - by Debopam

  I just started using IBM Worklight 5.0. I have been going through the HTTP Adapters recently and have successfully been able to Run as "Invoke Worklight Procedure". But I am stuck with the Adapter execution in the App. To my knowledge I think this is some kind of security issue where the client request to Worklight Server is unauthorized (401). Can any tell me or refer to some blog/website where there are steps to overcome this problem? I already got some of the websites but at this moment I am really confused on how to use them.

• What is the most under-valued part of .NET?

  - by Jan Bannister

  The .NET framework is massive. I've used it for years and I've still not used most of it. I'd like to expand my knowledge of the Framework's backwaters but just reading thought it seems daunting. So I thought I'd tap up the Stack Overflow community first. What part have you found to be the most surprisingly useful? What's your favourite obscure namespace? And conversely are there any shiny bits that are best avoided?

• Are frameworks really necessary for beginners/intermediates? (PHP)

  - by ggfan

  I have been programming for around 6months and currently learning PHP/Mysql. I can create basic functionally sites starting from a plain sheet of paper. Is it necessary I use frameworks to create sites? Currently, everything I do is from scratch. I'll borrow codes from old codes, ask people for help, etc. Are frameworks going to help me much more? Is it alright if I put a site public without using a framework? (I have not looked a lot into frameworks, so my knowledge is limited, but I'm just curious)

• C++ streams question (explanation of comment in code)

  - by skyeagle

  I am playing around with the fastCGI application found here. The following comment is in the code: if (content) delete []content; // If the output streambufs had non-zero bufsizes and // were constructed outside of the accept loop (i.e. // their destructor won't be called here), they would // have to be flushed here. My knowledge of C++ streams is rather weak. Could someone please explain the following: which streambufs are being referred to in the comment? under what conditions would the streambufs had non-zero bufsizes? last but not the least, can someone point to a resource (pun intended) online that provides a clear but gentle introduction to C++ IO streams?
