• What things can I teach a group of children about programming in one day?

  - by Rich Bradshaw

  I'm running a day for 30 kids aged 11-18 about computer game programming. They have all opted to do it, but they have no experience at all of programming. My main aim is for them to learn a few things: programming is hard/challenging programming is something they can learn to do being a computer games programmer != playing games all day a little more insight into how games actually work I'd thought of splitting them into two groups, of younger/less experience and older/more experience, then doing slightly different things. I'd considered showing them Scratch, Game Maker, before showing them the basics of Python and getting them to write a simple text based game (perhaps something like, computer picks a random number, you have to guess it in as few guesses as possible, computer says higher/lower for each guess). Does anyone have any ideas of things to do/show them/ways to teach them?

• Factory Method Using Is/As Operator

  - by Swim

  I have factory that looks something like the following snippet. Foo is a wrapper class for Bar and in most cases (but not all), there is a 1:1 mapping. As a rule, Bar cannot know anything about Foo, yet Foo takes an instance of Bar. Is there a better/cleaner approach to doing this? public Foo Make( Bar obj ) { if( obj is Bar1 ) return new Foo1( obj as Bar1 ); if( obj is Bar2 ) return new Foo2( obj as Bar2 ); if( obj is Bar3 ) return new Foo3( obj as Bar3 ); if( obj is Bar4 ) return new Foo3( obj as Bar4 ); // same wrapper as Bar3 throw new ArgumentException(); } At first glance, this question might look like a duplicate (maybe it is), but I haven't seen one exactly like it. Here is one that is close, but not quite: http://stackoverflow.com/questions/242097/factory-based-on-typeof-or-is-a

• Need url's to be non secure when moving away from a secured link (without hardcoded url's in html)?

  - by Tony_Henrich

  I have an asp.net site. It has an order form which is accessible at https://secure.example.com/order.aspx. The links on the site do not include the domain name. So for example the home page is 'default.aspx'. The issue is that if I click on a link like the home page from the secure page, the url becomes https://secure.example.com/default.aspx instead of http://www.example.com/default.aspx. What's a good way to handle this? The scheme should automatically work using any domain name based on where it's launched from. So if the site is launched from 'localhost', moving away from the secured page, the url's should be http://localhost/... The navigation links are in a master page.

• C++ - Efficient way to iterate over the contents of a vector?

  - by Francisco P.

  Hello, everyone! I am implementing a text-based version of Scrabble for a college project. I have a vector containing around 400K strings (my dictionary), and, at some point in every turn, I'm going to have to check if any word in the dictionary can be formed with the pieces in the player's hand. My only solution to this is iterating through the string, one by one, and using a sub-routine I have to check if the string in question can be formed from the player's pieces. I'll implement a quickfail checking if the user has any vowels, but it'll still be woefully inefficient. Any suggestions? Thanks for your time!

• Detecting and reloading updated application parameters at runtime

  - by VeeKayBee

  I am working on an ASP.NET web application(using .NET 4.5 and C#).The application deals with lot of units (for measuring like KG,Litre,KM etc). So based on the selected unit we have to implement some allowed range.This values can be configured without much effort. We identified two solutions for this Keeping a configuration xml. Suppose the values in xml, does it requires an iisreset or any other thing which can take the site down for some time, if we are changing the xml file to change some validation. Keeping in Db, then use SQL dependency caching. So an update to DB can reflect the caching values.SO i believe if we change the values, it will update the cache. How much complex is this and does it effect the performance ? It will be great helpful, if we have some other method to achieve this. Thanks in advance.

• Getting confused why i dont get expected amount ?

  - by Stackfan

  I have 1 result and which i will receive in Bank account, Based on that account i have to Put a balance to user account. How can you find the Handling cost from total tried 491.50 / 0.95 = 517.36 which is wrong ? It should be 500.00 (to my expectation) User balance requires 500.00 When 500.00 selected he gets 5% discount There is a handling cost for this ex: 1) Discount: 500.00 - 5% = 475.00 2) Handling cost: (475.00 x 0.034) + 0.35 = 16.50 3) Total: 475.00 + 16.50 = 491.50 So problem is from 491.50, i have to find atleast handling cost to get promised Balance. Any solution ? Cant figure it out myself...

• How does HTTP Analyzer works?

  - by Rampage

  Halo, i am interest in methods, which http analyzer uses to capture data. I would like to write program which saves emails sent via web based clients. The problem is https and HTTP Analyzer solves it, but i dont know how. I got one interesting answer on my question before, but it doesnt reveal as much as i would like to know. Programs like HTTP Analyzer can catch the HTTPS data because they insert themselves in the HTTPS stack. As a result, they get the data after it's generated but before it's being encrypted and put in IP packets. This is highly non-trivial. How it is possible to make? If you have any interesting articles solving this issue, please let me know.

• Save objects to a database?

  - by Eric

  So far in my .Net coding adventures I've only had a need to save information to files. So I've used XmlSerializer and DataContractSerializer to serialize attributed classes to XML files. My next project, however, requires that I save and retrieve information from a SQL server database. I'm wondering what my options are for doing this. The current version of the app, which was not created by me, uses a lot of hard coded SQL commands. But now I'm trying to avoid doing anything where I have to read or write individual fields to or from the database or objects. I especially want to avoid a lot of hard coded SQL in my code. I like how the serializer classes just figure out how to read and write XML files based on the attributes and or public properties of the class. Is there something similar for a database rather then XML?

• Firing events in script task

  - by Anonymouslemming

  I've got an SSIS project where I am constructing an SQL command based on some variables. I'm constructing the command in a script task, and want to output the constructed SQL to the 'Execution Results' window. I am trying to do this using a FireInformation line from inside my script as follows: Dts.Events.FireInformation(99, "test", "Make this event appear!", "", 0, true); However, in the script editor when editing ScriptMain.cs, that line is underlined in red, and on mouseover, I get the following message: Error: The best overloaded method match for 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.EventsObjectWrapper.FireInformation(int, string, string, string, int, ref bool') has some invalid arguments As a result, my script does not compile and I cannot execute it. Any idea what I'm doing wrong here, or what I need to change to be able to see the values of my variables at this point in the Execution output?

• clever way to conditionally split this string?

  - by sprugman

  I've got a string that could be in one of two forms: prefix=key=value (which could have any characters, including '=') or key=value So I need to split it either on the first or second equals sign, based on a boolean that gets set elsewhere. I'm doing this: if ($split_on_second) { $parts = explode('=', $str, 3); $key = $parts[0] . '=' . $parts[1]; $val = $parts[2]; } else { $parts = explode('=', $str, 2); $key = $parts[0]; $val = $parts[1]; } Which should work, but feels inelegant. Got any better ideas in php? (I imagine there's a regex-ninja way to do it, but I'm not a regex-ninja.;-)

• printf'ing a matrix

  - by Flavius

  I'm trying to implement an all-purpose function for printing 2D data. What I've come up with is: int mprintf(FILE* f, char* fmt, void** data, size_t cols, size_t rows) The challenge is determining how many bits to read at once from data, based on fmt. The format fmt is going to be the stdlib's-specific format for printf() and alike. Do you have any knowledge of already-existing features from stdlibc (GNU GCC C's) I could use to ease this up? I try avoiding having to do it all manually, because I know "I am stupid" (I don't want to introduce stupid bugs). Thus, reusing code would be the bug-freest way. Thanks Addendum I see there's a /usr/include/printf.h. Can't I use any of those functions to do it right and ease my job at the same time?

• Go, AppEngine: How to structure templates for application

  - by laslowh

  How are people handling the use of templates in their Go-based AppEngine applications? Specifically, I'm looking for a project structure that affords the following: Hierarchical (directory) structure of templates and partial templates Allow me to use HTML tools/editors on my templates (embedding template text in xxx.go files makes this difficult) Automatic reload of template text when on dev server Potential stumbling blocks are: template.ParseGlob() will not traverse recursively. For performance reasons it has been recommended not to upload your templates as raw text files (because those text files reside on different servers than executing code). Please note that I am not looking for a tutorial/examples of the use of the template package. This is more of an app structure question. That being said, if you have code that solves the above problems, I would love to see it. Thanks in advance.

• What to use to write tests? [Rails]

  - by yuval

  I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

• How much market shares OpenGL2.0 in iPhone os hardwares(iPhone/iPot Touch)

  - by Eonil

  I'm planning making a game for AppStore, so I'm studying GLES. But, GLES 1.1 and 2.0 APIs are different about handling in some features.(and limitations) I have not enough time to consider both of them, I have to choosing one. 2.0 is clearly better in developer's view, but I'm worry about it's market share. I wish most users moved on newer SGX based hardware, but in fact, I don't know. Does anybody have information about location of those hardware ratio data in iPhone OS supported hardwares? (iPhone/iPod touch, per GPU) Please let me know.

• Subversion Copy Hook on Windows

  - by GeoSQL

  Hi I am working on a web based project in my free time. I have SVN set up on my machine (running XP). What I would like to do is have a copy of my repository copied to the htdocs folder (Dev machine) post-commit via a hook. That way I can test my changes in a browser. I know that I can write up a .bat file, but I'm not sure what the syntax would be. I can do a basic DOS Copy command, but I saw one example that provided a username and password to SVN at copy time. Do I need to do this? Can someone point me in the right direction as far a syntax for the .bat file? Or maybe even suggest a better method. Thanks

• What GC parameters is a JVM running with?

  - by skaffman

  I'm still investigating issues I have with GC tuning (see prior question), which involves lots of reading and experimentation. Sun Java5+ JVMs attempt to automatically select the optimal GC strategy and parameters based on their environment, which is great, but I can't figure out how to query the running JVM to find out what those parameters are. Ideally, I'd like to see what values of the various GC-related -XX options are being used, as selected automatically by the VM. If I had that, I could have a baseline to begin tweaking. Anyone know to recover these values from a running VM?

• How to deal with multiple screensizes + dynamic controls in Android?

  - by chobo2

  Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

• MVC3 application I want javascript methods to fire on passed in route values

  - by DavieDave

  I have an MVC3 application in Visual Studio 2010. I have a view with several dropdowns that do javascript calls to populate dropdowns based on the selected value, some of which are disabled initially. That all works great with the initial state of nothing. If I however pass routevalues to the dropdowns from a redirect to this action, I do get the value set correctly but it's not enabled like it should be on the dropdown for example and when I post the form, the ones that are greyed out are not passed back on the form. How can I correct this?

• C++ - Efficient container for large amounts of searchable data?

  - by Francisco P.

  Hello, everybody! I am implementing a text-based version of Scrabble for a College project. My dictionary is quite large, weighing in at around 400.000 words (std::string). Searching for a valid word will suck, big time, in terms of efficiency if I go for a vector<string> ( O(n) ). Are there any good alternatives? Keep in mind, I'm enrolled in freshman year. Nothing TOO complex! Thanks for your time! Francisco

• Broadcast message or file to nearby Bluetooth devices

  - by Medjeti

  Hiya, A client of ours is attending a business fair and would like to push some sort of "welcome message" to people visiting their space. I'm not too familiar with Bluetooth, so I have a few questions: What kind of content can you transfer via Bluetooth? (Is it files only or is it possible to send a simple text message?) Is it possible to push content only to recipients within a certain distance? (ie. based on signal strength or similar) Can anybody recommend a piece of software that can do some or all of the above? If necessary we could program a custom solution ourselves (.NET), but I'm sure there must be a program out there that can do the job. I've googled a bit and came across the 32feet.NET framework - does anybody have any experience with this framework? Thanks in advance for any suggestions!

• Is it possible to dynamically change the style/template of a control?

  - by elggarc

  I am creating a UserControl in Silverlight 4 which has a watermarked background. The watermark should change depending on the underlying 'type' the UserControl is representing. The watermark is created using a Path and I have extracted all the properties into a style. I was wondering if it would be possible to change the style of the Path at runtime based on some known value. I am using MVVM and Unity. Perhaps I could bind the style somehow? Or could I inject the style when the view is created? I may have to do this with control templates, hence the reference in the title. Thanks...

• Log4Perl - how to set exit code if any WARN, ERROR, or FATAL messages?

  - by pdxrlk

  Hi - I've been using Log4Perl extensively in a number of scripts. I'd like to augment those scripts to set an error code if any WARN or ERROR messages have been logged. I couldn't find any obvious way to do this based on existing documentation. I'd like to avoid a brute-force rewrite of my existing scripts to add a check on every WARN or ERROR log message; I'd prefer to handle it prior to script exit if possible like this pseudocode: if $log->has_warnings_or_errors then exit 1 else exit 0 Is there any easy way to call Log4Perl to determine if the current logger has issues messages of certain levels? Thanks.
