• MTU mismatch between GetIfEntry and netsh

  - by ChrisJ

  I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

• Python 2 vs Python 3 and Tutorial

  - by MR-J

  Hey guys. I am 12 years old and I have had a small amount of experience with BASIC. I am thinking about learning Python, but I’m not sure if I should learn the 2.6 version or the 3.0 version. I don’t really care about the support for libraries or anything along those lines quite yet. I was wondering if it is easier to code in 3.0 than 2.6. And is it more fun and productive? I would also appreciate it if you could point me in the right direction for a simple yet complete tutorial that is easy to understand and possible teaches Object Oriented Programing. I don’t really care if it teaches OOP or not. One more thing; if I do learn python, is it possible to easily compile a python source code file into a 'stand-alone' .exe file for Windows? I really liked that functionality in BASIC. Thanks!!!!

• A metaphor for Drupal module's inner workings

  - by PHP thinker

  What is the best application workflow metaphor for Drupal module? In PHP frameworks we think MVC-style. How do we think inside Drupal? Asumming I am writing some user-oriented module like Shop, Catalog or Forum. As far as I understand there are no or few MVC based modules. Should I generally treat Drupal modules (as sub-application) as a number of screens connected via forms and hyperlinks or there is a better way. My question may be a little bit speculative, but I hope someone will share my intent to think models, not just "scripts".

• C# Object Creation from Datatable

  - by Jonesy

  Hi Folks, Im just getting my head round C#. I've been creating classes and objects so say i created a class called Member: public class Member { public int MemberID; public string FirstName; public string LastName; public string UserName; } and i create a new object of that class by doing this: Member Billy = new Member(); Billy.UserName = "Jonesy"; Billy.FirstName = "Billy"; Billy.LastName = "Jones"; Thats all fine but what if I've queried a database and gotten back 5 members, can I create objects on the fly? Or what is the best way to store these members in memory? I've used VB.Net where I would just add them into a datatable. But I've never really done any object-oriented programming before and thought since I'm learning C sharp nows the best time to learn OOP.. Any help most appreciated! Jonesy

• How do I render 3d model into directshow virtual camera output

  - by Mr Bell

  I want to provide a virtual webcam via DirectShow that will use the video feed from an existing camera running some tracking software against it to find the users face and then overlay a 3d model oriented just that it appears to move the users face. I am using a third party api to do the face tracking and thats working great. I get position and rotation data from that api. My question is whats the best way to render the 3d model and get into the video feed and out to direct show? I am using c++ on windows xp.

• Address calling class [Java]

  - by Samuel

  Hello! [I am rather new to Java and Object Oriented programming] I have an abstract class Moveable with the method abstract void move() which is extended by the class Bullet and the abstract class Character, and Character is extended by the class Survivor and the class Zombie. In Survivor and Bullet the move() method doesnt require any parameters while in the class Zombie the move() method depends on the actual position of the survivor. The survivor and multiple zombies are created in the class Gui. I wanted to access the survivor in Zombie - what's the best way of doing this? In Gui i wrote a method getSurvivor() but i don't see how to access this method in Zombie? I am aware that as a workaround i could just pass a [Survivor survivor] as parameter in move() and ignore it in Bullet and Survivor, but that feels so ... bad practice. Thank you for your time! Samuel [I am not sure what tags to set here, please correct me if i'm wrong]

• WPF layout with several fixed height parts and certain parts relative to window size

  - by Daniil Harik

  Hello, At moment my main layout consists of vertically oriented stack panel and it looks like this: Root StackPanel StackPanel - fixed Height 150 (horizontal orientation) StackPanel - relative Height must be behalf of free space left on screen (but at least 150 px). Used by Telerik GridView Control, if I don't specify Height or MaxHeight Telerik GridView Height becomes very large and does not fit my window. StackPanel - fixed Height 100 (horizontal orientation) StackPanel - relative Height must be half of free space left on screen (but at least 150 px). Used by Telerik GridView Control, if I don't specify Height or MaxHeight Telerik GridView Height becomes very large and does not fit my window. StackPanel - fixed Height 100 (horizontal orientation) The view must totally fit available screen size. The problem is that I don't understand how to make certain areas of my view resize depending on available screen size. Is there is easy way to solve it, or should I be binding to Window height property and doing math? Thank You very much!

• JAVA Classes in Game programming.

  - by Gabriel A. Zorrilla

  I'm doing a little strategy game to help me learn Java in a fun way. The thing is I visioned the units as objects that would self draw on the game map (using images and buffering) and would react to the mouse actions with listeners attached to them. Now, based on some tutorials I've been reading regarding basic game programming, all seems to be drawn in the Graphics method of my Map class. If a new unit emerges, i just update the Map.Graphics method, it's not as easy as making a new Unit object which would self draw... In this case, I'd be stuck with a whole bunch of Map methods instead of using classes for rendering new things. So my question is, is it possible to use classes for rendering units, interface objects, etc, or i'll have to create methods and just do some kind of structural programming instead of object oriented? I'm a little bit confused and I'd like to have a mental blueprint of how things would be organized. Thanks!

• Css editor with certain features

  - by user255408

  I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

• Lua API for TokyoTyrant

  - by jideel

  Hi SO folks, I didn't managed to find an Lua client/api for TokyoTyrant. Such Api exists for TokyoCabinet, but not for TT. And Perl and Ruby API exists for TT. TT provides a native binary protocol, a memcached-compatible protocol, and an HTTP-oriented protocol. So my questions are : 1/ Do you think using the memcached (using luamemcached) or the HTTP protocol (using luaSocket) is "enough" for most / simple usage, and so a native Lua api is not necessary ? (the app is a simple uuid storage/distributor) ? 2/ Does it make sense to not use TokyoTyrant, but only TokyoCabinet, and use Lua at the application level to provide network and concurrent access to TC, using, say, Copas (Copas is , from their website, "a dispatcher based on coroutines that can be used by TCP/IP servers." ? Thanks.

• What features are important in a programming language for young beginners?

  - by NoMoreZealots

  I was talking with some of the mentors in a local robotics competition for 7th and 8th level kids. The robot was using PBASIC and the parallax Basic Stamp. One of the major issues was this was short term project that required building the robot, teaching them to program in PBASIC and having them program the robot. All in only 2 hours or so a week over a couple months. PBASIC is kinda nice in that it has built in features to do everything, but information overload is possible to due this. My thought are simplicity is key. When you have kids struggling to grasp: if X>10 then <DOSOMETHING> There is not much point in throwing "proper" object oriented programming at them. What are the essentials needed to foster an interest in programming?

• Which OOD approach should I take?

  - by Sorush Rabiee

  According to Niklaus Wirth, Algorithms + Data Structures = Programs. So I use this as a start point to object-oriented modeling and inheritance design: in a way that I separate the 'Objects' from 'Operations'. then look for patterns and inheritance hierarchy. But now after practice I guess it's not a good idea for every modeling problem, because sometimes it's not effective. (I mean there is no possibility of developing (or is very hard to develop) codes of Turing-Completed languages based on this paradigm.) What is your viewpoint for designing an OOD structure as an experienced programmer?

• Running Awk command on a cluster

  - by alex

  How do you execute a Unix shell command (awk script, a pipe etc) on a cluster in parallel (step 1) and collect the results back to a central node (step 2) Hadoop seems to be a huge overkill with its 600k LOC and its performance is terrible (takes minutes just to initialize the job) i don't need shared memory, or - something like MPI/openMP as i dont need to synchronize or share anything, don't need a distributed VM or anything as complex Google's SawZall seems to work only with Google proprietary MapReduce API some distributed shell packages i found failed to compile, but there must be a simple way to run a data-centric batch job on a cluster, something as close as possible to native OS, may be using unix RPC calls i liked rsync simplicity but it seem to update remote notes sequentially, and you cant use it for executing scripts as afar as i know switching to Plan 9 or some other network oriented OS looks like another overkill i'm looking for a simple, distributed way to run awk scripts or similar - as close as possible to data with a minimal initialization overhead, in a nothing-shared, nothing-synchronized fashion Thanks Alex

• Difference between Apache Tapestry and Apache Wicket

  - by Stephan Schmidt

  Apache Wicket ( http://wicket.apache.org/ ) and Apache Tapestry ( http://wicket.apache.org/ ) are both component oriented web frameworks - contrary to action based frameworks like Stripes - by the Apache Foundation. Both allow you to build your application from components in Java. They both look very similar to me. What are the differences between those two frameworks? Has someone experience in both? Specifically: How is their performance, how much can state handling be customized, can they be used stateless? What is the difference in their component model? What would you choose for which applications? How do they integrate with Guice, Spring, JSR 299? Edit: I have read the documentation for both and I have used both. The questions cannot be answered sufficently from reading the documentation, but from the experience from using these for some time, e.g. how to use Wicket in a stateless mode for high performance sites. Thanks.

• How do I get developers to treat test code as "real" code?

  - by womp

  In the last two companies I've been at, there is an overriding mentality among developers that it's okay to write unit tests in a throw-away style. Code that they would never write in the actual product suddenly becomes OK in the unit tests. I'm talking Rampant copying and pasting between tests Code styling rules not followed Hard-coded magic strings across tests No object-oriented thought or design for integration tests, mocks or helper objects (250 line single-function tests!) .. and so on. I'm highly dissatisfied with the quality of the test code. Generally we do not do code reviews on our test assemblies, and we also do not enforce style or code analysis of them on our build server. Is that the only way to overcome this inertia about test quality? I'm looking for ideas to take to our developers, without having to go to higher management saying that we need to use resources for enforcement of test quality (although I will if I have to). Any thoughts or similar experiences?

• Is there a way to watch all COM activity on a computer?

  - by Fake Name

  I'm trying to deal with a piece of specialized hardware, that presents it's interface as a COM object, using win32com in Python. However, the documentation for how to actually set up the hardware through the COM object is sparse (it requires a significant amount of initialization), and entirely oriented at using a bunch of pre-built libraries for Visual Studio, which are not accessible through python. That said, is there any way to watch all local COM activity, so I can sort through the activity logs to try and figure out how the existing demo programs properly initialize the hardware, and replicate the behavior in my python script? Ideally, there would be something in the vein of wireshark for doing this. Note: I have very little (read: basically no) experience using COM, as my focus is mostly embedded hardware (and a little python dev on the side). However, I'm stuck with this particular device.

• What to name this class?

  - by orlandu63

  (This is not an interface: I simply omitted the method bodies) class _ { protected $_data = array(); function __construct($data); function set($name, $value); function get($name); function __set($name, $value); function __get($name); //aliases for their respective non-magic methods. # and some other generic methods } Essentially it's a class that provides a magical object-oriented reusable access layer to some data. I've considered DataLayer, DataObject and some others; I'd like to hear some suggestions from someone who's more terminologically savvy.

• Are these tables too big for SQL Server or Oracle

  - by Jeffrey Cameron

  Hey all, I'm not much of a database guru so I would like some advice. Background We have 4 tables that are currently stored in Sybase IQ. We don't currently have any choice over this, we're basically stuck with what someone else decided for us. Sybase IQ is a column-oriented database that is perfect for a data warehouse. Unfortunately, my project needs to do a lot of transactional updating (we're more of an operational database) so I'm looking for more mainstream alternatives. Question Given these tables' dimensions, would anyone consider SQL Server or Oracle to be a viable alternative? Table 1 : 172 columns * 32 million rows Table 2 : 453 columns * 7 million rows Table 3 : 112 columns * 13 million rows Table 4 : 147 columns * 2.5 million rows Given the size of data what are the things I should be concerned about in terms of database choice, server configuration, memory, platform, etc.?

• Implementing website messaging services

  - by Alex

  There's a website which currently has only web interfaces for all the users. However, new requirement has emerged which says that there is a need in providing an alternative interface for a certain group of website users who want to regularly receive pushed notifications(messages) that would inform them about new events(news) in their field of interest. What sort of interface would it be?Is it all about using a MOM(message-oriented middleware) like JMS and deploying it withing an application server on a website using publish/subscribe model?Is it the correct way how to meet these sort of requirements?And if it's not a web-based interface,would kind of interface would it be then for the users?

• Why Banks or Financial Companies prefer Oracle than other RDBMS for their "Core" systems?

  - by edwin.nathaniel

  I'd like to know why most Banks or Financial companies prefer Oracle than other RDBMS for their core systems (the absolutely minimum features that a Bank must support). I found a few answers that didn't satisfy me. For example: Oracle has more features. But features for what? Can't you implement that in application level if you were not using Oracle? Could someone please describe a bit more technical but still on high-level overview of what the bank needs and how Oracle would solve it and the others can't or don't have the features yet? I came from the web-app (web 2.0) crowd who normally hear news about MySQL, PostgreSQL or even key-value/column-oriented storage solution. I have almost zero knowledge on how Banks or Financial companies operates from technical perspective. Thank you, Ed

• Best Online Programming Degree? (Masters Level)

  - by Jason

  I am less then a year from graduating with my bachelors in web development, however I would like to continue on with a masters in programming. As far as I can tell, what I want is a masters in software engineering. Sadly my current college only offers more management oriented masters level degrees, and I want something that is programming, not business. Ultimately my goal is to teach online and work freelance on the side. Here's the problem - I am visually impaired, so I do not drive and I prefer to take my classes entirely online. I have heard enough to avoid university of phoenix... and I have heard some good about walden, regis, and penn state's online MSSE programs. I am wondering if anyone here knows of any other good ones, or ones I should avoid. I have heard mixed reviews of Colorado Tech.

• Custom calendar drag drop event: Find date dropped to

  - by cpf

  Hi stackoverflow, I've been working in silverlight to do a date-oriented application. I started off with changing the calendar template to contain a listbox on every date, and I created a listbox containing simple items. I implemented an easy drag drop on both those elements, so now I can drag from the listbox containing the items to the listbox on a date and have an event. Downside is: In the event, I don't know which date it was dropped to. How can I figure this out? Please note: The date dropped to is not necessarily the date currently selected...
