• Is there a way to convert a swf to an .abc file?

  - by Jeremy Ruppel

  I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

• Right way to create [self]respawning app in python

  - by grapescan

  I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself. The goal is to make it "self-respawning". I have some variants about how to do it. Bot is one process. Another process monitors its activity and starts it if bot died. Main process spawns bot subprocess and controls it. Also I think daemonizing bot process is useful here. Platform is Linux, as you could guess. What is the right way to solve this problem?

• asp.net free webcontrol to display crosstab or pivot reports with column and row grouping, subtotals

  - by dev-cu

  Hello, I want to develop some crosstab also know as pivot reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.

• Matlab tutorial for programmers

  - by Jonas

  I'm getting some new students soon, who will be writing Matlab code. They're new to Matlab, but they have experience coding in Java and C++. I'm going to have them go through the 'Getting Started' section of the Matlab help. In addition, I want to give a small tutorial with the goal to prevent them from making some of the most common mistakes people make when switching to Matlab ("Matlab starts counting at 1"), and show them some features that they may not be aware of when coming from other languages ("you can subtract a scalar directly from an array, and for vectors, there's bsxfun"). What are the most important things I should tell them?

• DJ JWebBrowser: how to show but disable Address and Button bars?

  - by Nikolay Kuznetsov

  I am using chrriis.dj.nativeswing.swtimpl.components.JWebBrowser in my swing application to open web page. The page is going to show "Facebook Authentication" page and I want to prevent user from inputting some other URL other than I specify and also Forward and Back buttons should be visible but not has no affect. So following functions are applicable for my goal setButtonBarVisible(true); setLocationBarVisible(true); Once user completes the authentication I will handle the locationChanged event. @Override public void locationChanged(WebBrowserNavigationEvent arg0) { System.out.println("locationChanged!"); .... } }

• SQL bottleneck, how to fix

  - by masfenix

  This is related to my previous thread: http://stackoverflow.com/questions/3069806/sql-query-takes-about-10-20-minutes However, I kinda figured out the problem. The problem (as described in the previous thread) is not the insert (while its still slow), the problem is looping through the data itself Consider the following code: Dim rs As DAO.Recordset Dim sngStart As Single, sngEnd As Single Dim sngElapsed As Single Set rs = CurrentDb().QueryDefs("select-all").OpenRecordset MsgBox "All records retreived" sngStart = Timer Do While Not rs.EOF rs.MoveNext Loop sngEnd = Timer sngElapsed = Format(sngEnd - sngStart, "Fixed") ' Elapsed time. MsgBox ("The query took " & sngElapsed _ & " seconds to run.") As you can see, this loop does NOTHING. You'd expect it to finish in seconds, however it takes about 857 seconds to run (or 15 minutes). I dont know why it is so slow. Maybe the lotusnotes sql driver? any other ideas? (java based solution, any other solution) What my goal is: To get all the data from remote server and insert into local access table

• removing duplicate strings from a massive array in java efficiently?

  - by Preator Darmatheon

  I'm considering the best possible way to remove duplicates from an (Unsorted) array of strings - the array contains millions or tens of millions of stringz..The array is already prepopulated so the optimization goal is only on removing dups and not preventing dups from initially populating!! I was thinking along the lines of doing a sort and then binary search to get a log(n) search instead of n (linear) search. This would give me nlogn + n searches which althout is better than an unsorted (n^2) search = but this still seems slow. (Was also considering along the lines of hashing but not sure about the throughput) Please help! Looking for an efficient solution that addresses both speed and memory since there are millions of strings involved without using Collections API!

• F#: Define an abstract class that inherits an infterface, but does not implement it

  - by akaphenom

  I owuld like to define an abstract class that inerhits from UserControl and my own Interface IUriProvider, but doesn't implement it. The goal is to be able to define pages (for silverlight) that implement UserControl but also provide their own Uri's (and then stick them in a list / array and deal with them as a set: type IUriProvider = interface abstract member uriString: String ; abstract member Uri : unit -> System.Uri ; end type UriUserControl() as this = inherit IUriProvider with abstract member uriString: String ; inherit UserControl() Also the Uri in the definition - I would like to implement as a property getter - and am having issues with that as well. this does not compile type IUriProvider = interface abstract member uriString: String with get; end Thank you...

• Possible to view T-SQL syntax of a stored proc-based SqlCommand?

  - by mconnley

  Hello! I was wondering if anybody knows of a way to retrieve the actual T-SQL that is to be executed by a SqlCommand object (with a CommandType of StoredProcedure) before it executes... My scenario involves optionally saving DB operations to a file or MSMQ before the command is actually executed. My assumption is that if you create a SqlCommand like the following: Using oCommand As New SqlCommand("sp_Foo") oCommand.CommandType = CommandType.StoredProcedure oCommand.Parameters.Add(New SqlParameter("@Param1", "value1")) oCommand.ExecuteNonQuery() End Using It winds up executing some T-SQL like: EXEC sp_Foo @Param1 = 'value1' Is that assumption correct? If so, is it possible to retrieve that actual T-SQL somehow? My goal here is to get the parsing, etc. benefits of using the SqlCommand class since I'm going to be using it anyway. Is this possible? Am I going about this the wrong way? Thanks in advance for any input!

• MySQL: Transactions across multiple threads

  - by Zombies

  Preliminary: I have an application which maintains a thread pool of about 100 threads. Each thread can last about 1-30 seconds before a new task replaces it. When a thread end, that thread almost always will result in inserting 1-3 records into a table, this table is used by all of the threads. Right now, no transactional support exists, but I am trying to add that now. So... Goal I want to implement a transaction for this. The rules for whether or not this transaction commits or rollback reside in the main thread. Basically there is a simple function that will return a boolean. Can I implement a transaction across multiple connections? If not, can multiple threads share the same connection? (Note: there are a LOT of inserts going on here, and that is a requirement).

• Open Source Contribution for a newbie programmer.

  - by sasayins

  Hi, I am teaching programming to my nephews and I want them to improve their skills by contributing to open source projects. Now my question is, do you know any open source project that suit for a newbie programmer. What I mean is, the project does not have a large codebase, the project is very interesting and the project is written in C because I chose C language as their starting language but you can suggest other project made in other language. My goal here are to improve their logic by reading other source codes, familiarize to the available development tools like bug tracker, version control system, etc. and open their interest in open source community. Thanks. =)

• What is a programmer's life like?

  - by Zee JollyRoger

  Imagine like an 8-hour long video of any "typical/average" programming job. What is it like? Before I get myself involved in that path, what can I expect? I am interested in gathering first-hand information and accounts of the typical life of a programmer. My goal is to grasp the fundamental concepts of working in the professional field of programming. I just want to "see" into what it is/means to come to an entry-level programming job and program. See what kind of skills, mentality, expectations, and such are required.

• Mixing static and dynamic endpoints in app.yaml file

  - by Greg

  I'm trying to describe endpoints in my App Engine app and am having difficulty for directory structures that mix static and dynamic content. But my yaml rules are conflicting with one another. Before I change my directory structure, does anyone have a recommendation? The goal is to create a directory that contains both documentation (static html files) and implementations. /api - /v1 - getitdone.py - doc.html - index.html What I think I should be doing with my application yaml... - url: /api/v1/getitdone script: api/v1/getitdone.py - url: /api/ static_files: api/index.html upload: api/index.html - url: /api static_dir: api But this causes the dynamic endpoints to fail. I'm assuming the static_dir reference is breaking it. How can I do this without describing every script and static file reference (I have many more than are listed here)?

• Partial compilation of openwrt project

  - by yosig81

  I would like to get an idea or reference to compile only subset on the openwrt project. i am aware of the menuconfig utility but this is not enough for my goal. i would like to compile only the tool-chain (binutils + gcc + glibc) for a specific target (ar71xx) and also the kernel. now, after looking in the makefiles etc, i have noticed that most of the work in actually patching the toolchain and the kernel and then compile it. is there any option to stop build process after the patching so i can have only the source code patched and i can write my own make file to compile it?

• Hudson build defaults

  - by toluju

  This has been a fairly long-standing problem for us with our Hudson installation, and searching around the Hudson Wiki / Issue Tracker hasn't yielded any insight to this. The question: Is it possible to set certain default values for a maven2 build in Hudson? For example, we want all our projects to run the "clean" goal before a build, we want all our builds to poll the SCM hourly, and we want all our builds to deploy to our maven repository on build success. Right now, we have to manually set these setting for every project individually, which can be rather time consuming as we have 30+ different projects all being managed by Hudson. This is especially annoying if we need to change a particular setting that will affect all projects (e.g. change the repository URL). Given that I couldn't find any mention of this on the Wiki or Issue Tracker leads me to believe that I'm missing something obvious, but I cannot find an answer on my own.

• Windows 32 or 64 bit using HKEY_LOCAL_MACHINE\Software\WOW6432 Node

  - by JimDel

  I'm looking for a very simple way of determining if the version of Windows the customer is using is 32bit or 64bit. I know there are ways using .NEt but I'm looking to avoid them. I simply want to use something similar the below pseudo code and want to know if this method can be reliable. If Registry Key exists (HKEY_LOCAL_MACHINE\Software\WOW6432Node) Then Assume 64bit else Assume 32bit Thanks! EDIT: To be more specific, I know there a several different ways to accomplish the goal of finding out if the OS is 32 or 64bit. But I want to know if the above alone method would be reliable.

• Are there any tools to help the user to design a State Machine to be consumed by my application?

  - by kolrie

  When reading this question I remembered there was something I have been researching for a while now and I though Stackoverflow could be of help. I have created a framework that handles applications as state machines. Currently all the state business logic and transactions are handled via Java code. I was looking for some UI implementation that would allow the user to draw the state machines and transactions and generate a file that can later on be consumed by my framework to "run" the workflow according to one or more defined state machines. Ideally I would like to use an open standard like SCXML. The goal as the UI would be to have something like this plugin IBM have for Rational Software Architect: Do you know any editor, plugin or library that would have something similar or at least serve as a good starting point?

• How would one use Cocos2d to create a game like this.

  - by John Stewart

  http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&ign-mpt=uo%3D6 So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is not going to be a market release game. This is totally going to be learning purposes only. So to start off my question is: Would something like this be achievable using Cocos2d? How would I go about building the physics for this? How can one do a screen scroll like the way they do in cocos2d? (any example code would be great) This is just to start off. If you have any particular questions please do add to this question.

• facebook with openid

  - by Stacey

  Referencing http://stackoverflow.com/questions/1827997/is-facebook-an-openid-provider here. This is kind of an additional question based on it. I have also read the article at : http://stackoverflow.com/questions/2264266/what-is-the-openid-url-of-facebook - but I am still pretty confused on the whole ordeal. The goal is for people who use facebook to easily login to our website, not to neccessarily integrate with facebook and add things to it (yet). I have read the documentation on facebook connect and am still having trouble grasping exactly what we need to do to accomplish this. I notice that it says that facebook accepts openid logins - so in theory someone with a facebook account could login to a site that took other openid logins, correct? Or do I have to code a separate 'facebookconnect' system just to accept logins from facebook accounts?

• Help using Horner's rule and Hash Functions in JAVA?

  - by Matt

  I am trying to use Horner's rule to convert words to integers. I understand how it works and how if the word is long, it may cause an overflow. My ultimate goal is to use the converted integer in a hash function h(x)=x mod tableSize. My book suggests, because of the overflow, you could "apply the mod operator after computing each parenthesized expression in Horner's rule." I don't exactly understand what they mean by this. Say the expression looks like this: ((14*32+15)*32+20)*32+5 Do I take the mod tableSize after each parenthesized expression and add them together? What would it look like with this hash function and this example of Horner's rule?

• Interpreting Search Results

  - by Simon

  Hi all, I am tasked with writing a program that, given a search term and the HTML source of a page representing search results of some unknown search engine (it can really be anything, a blog, a shop, Google, eBay, ...), needs to build a data structure of the results containing "what's in the results": a title for earch result, the "details" link, the position within the results etc. It is not known whether the results page contains any of the data at all, and whether there are any search results. The goal is to feed the data structure into another program that extracts meaning. What I am looking for is not BeautifulSoup or a RegExp but rather some clever ideas or algorithms on how to interpret the HTML source. What do I do to find out what part of the page constitutes a single result item? How do I filter the markup noise to extract the important bits? What would you do? Pointers to fields of research covering what I try to to are aly greatly appreciated. Thanks, Simon

• How to use Preprocessor directives in MVC aspx pages

  - by Zuber

  I am using MinifyJS.tt which is a T4 template to minify all my JS files automatically. In my aspx files, I am referencing all the javascript files. Now, I want to add a condition (maybe compiler directive) to use the original JS file when I am debugging the application, and to use the minified JS files when I simply run the application without debug. I tried using #if in the aspx page, but that did not seem to work. Can we make use of preprocessor directives in aspx pages? Is there an alternative way to achieve my goal?
