• Blackberry development on scripting language ?

  - by zvr

  From what I've seen, the preferred way to develop Blackberry applications is Java. Is this the only way? I'm dreaming of a rapid application environment where you can create GUIs (using the Blackberry UI components). Something like a port of Tcl/Tk on Blackberry... or Python/Tkinter... or something new, but similar. Does something like that exist ? (I doubt it) Can something like that exist ? (i.e., given the money, is it feasible/reasonable/...)

• Creating a directory in linux assembly language

  - by Jayson Kane

  I am trying to create a small assembly program to create a folder. I looked up the system call for creating a directory on this page: http://www.ctyme.com/intr/rb-8144.htm It says that it is identified by 27h. How would I go about implementing the "mkdir somename" in assembly? I am aware that the program should move 27 into eax but I am unsure where to go next. I have googled quite a bit and no one seems to have posted anthing about this online. This is my current code (I don't know in which register to put filename and so on) section .data section .text global _start mov eax, 27 mov ???????? .... int 80h Thanks

• Are default mysql parameters in RDS sane?

  - by taw

  RDS uses the same set of parameters for all instance sizes and they don't seem to be that far from defaults (max_packet_size being too small etc.) Has anyone looked at them and reviewed them for how sensible they are, especially on relatively bigger instances?

• How to counter the "one true language" perspective?

  - by Rob Wells

  How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't realised that the modern software professional has a range of tools in his toolbox. The person whose knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach to open people up to the fact that "not everything is a nail"? How may I introduce them to having a well-equipped toolbox, selecting the best tool for the job at hand?

• Can you help with this assembly language code?

  - by Mugen

  Hi, I've been looking through a piece of code of a pc game that I'm trying to "improve". (ok so maybe I suck at the game but I still want to play it). Could you please look into the following code: fld dword ptr[ebp+00007B1C] fsub dword ptr[esp+64] fst dword ptr[ebp+00007B1C] call 004A2E48 This code is called every second for the level countdown timer. I need to stay on a particular level for a few minutes. If I can modify the above code so that the value pushed into the address [ebp+00007B1C] is 0 then the game level will always time out and it will save me playing those crazy "survival" minigames. I'll explain what I understand from this code. Dont worry, you dont have to go deep into this. In the first line we get the timer value. For example if 97 seconds are remaining then it is here that this value is loaded. In the second line a value (1 second) is subtracted from 97. In the third line 96 is again moved to memory. And finally we have the function call that will do other processing based on the time remaining. Now all I need to do is patch this piece of code somehow so that the value that is pushed is 0 (in the third step). Can you please help me out with this?

• Object tree navigation language in Java

  - by lewap

  In the system which I'm currently developing I often have to navigate an object tree and based on its state and values take actions. In normal Java this results in tedious for loops, if statements etc... Are there alternative ways to achieve tree navigation, similar to XPath for XML? I know there is JXPath and OGNL, but do you know any other libraries for such purpose? Do you know any libraries which generate bytecodes for specific tree navigation expressions to make the processing as fast as Java native fors and ifs?

• doctrine2: many-to-one with non default referencedColumnName does not persist entity

  - by timaschew

  I'm using symfony 2.1.2 with FOSUserBundle. I extend the User from FOS and define a many-to-one (bidirectional) association to a Customer entity. I don't want to use primary key for the association (referencedColumnName). I will use another integer uniqe column: customer_no use FOS\UserBundle\Entity\User as BaseUser; /** * @ORM\Entity * @ORM\Table(name="t_myuser") */ class MyUser extends BaseUser { /** * @ORM\ManyToOne(targetEntity="Customer", inversedBy="user") * @ORM\JoinColumn(name="customer_no", referencedColumnName="customer_no", nullable=false) */ $public $customer; } /** * @ORM\Entity * @ORM\Table(name="t_customer") */ class Customer extends BaseEntity // provides an id (pk) { /** * @ORM\Column(type="integer", unique=true, nullable=false) */ public $customer_no; /** * @ORM\OneToMany(targetEntity="MyUser", mappedBy="customer") */ public $user; } When I try to persist (via a form) a new MyUser entity with an (already in db existing and) loaded Customer entity from db, I get this error: Notice: Undefined index: customer_no in ...\vendor\doctrine\orm\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php line 608 The schema on the db is all right. //update: I fix the inversedBy and mappedBy stuff, but this is not the problem.

• asp.net 4.0 web forms routing - default/wildcard route

  - by Martin Robins

  I there a simple way when using ASP.NET 4.0 routing with Web Forms to produce a route that will act as some kind of wildcard? It seems to me that within WebForms, you have to specify a route for every page - I am looking for some kind of generic route that can be used where nothing specific is required, perhaps mapping directly from path to path so... http://somedomain.com/folder1/folder2/page would possibly map to folder1/folder2/page.aspx Any suggestions? Thanks

• Assigning a default value to a final variable in case of an exception in Java

  - by frenetisch applaudierend

  Why won't Java let me assign a value to a final variable in a catch block after setting the value in the try block, even if it is not possible for the final value to be written in case of an exception. Here is an example that demonstrates the problem: public class FooBar { private final int foo; private FooBar() { try { int x = bla(); foo = x; // In case of an exception this line is never reached } catch (Exception ex) { foo = 0; // But the compiler complains // that foo might have been initialized } } private int bla() { // You can use any of the lines below, neither works // throw new RuntimeException(); return 0; } } The problem is not hard to work around, but I would like to understand why the compiler does not accept this. Thanks in advance for any inputs!

• Complex queries using Rails query language

  - by Daniel Johnson

  I have a query used for statistical purposes. It breaks down the number of users that have logged-in a given number of times. User has_many installations and installation has a login_count. select total_login as 'logins', count(*) as `users` from (select u.user_id, sum(login_count) as total_login from user u inner join installation i on u.user_id = i.user_id group by u.user_id) g group by total_login; +--------+-------+ | logins | users | +--------+-------+ | 2 | 3 | | 6 | 7 | | 10 | 2 | | 19 | 1 | +--------+-------+ Is there some elegant ActiveRecord style find to obtain this same information? Ideally as a hash collection of logins and users: { 2=>3, 6=>7, ... I know I can use sql directly but wanted to know how this could be solved in rails 3.

• How to get the default audio format of a TTS Engine

  - by Itslava

  In Microsoft TTS 5.1 or newer. The SpVoice.AudioOutputStream property says: The AudioOutputStream property gets and sets the current audio stream object used by the voice. Setting the voice's AudioOutputStream property may cause its audio output format to be automatically changed to match the text-to-speech (TTS) engine's preferred audio output format. If the voice's AllowAudioOutputFormatChangesOnNextSet property is True, the format change takes place; if False, the format remains unchanged. In order to set the AudioOutputStream property of a voice to a specific format, its AllowOutputFormatChangesOnNextSet should be False. It means a engine's always has a preferred audio output format. So, how can i get it.. i have not found any interface to get that attribute.

• Is there a declarative language for data definitions?

  - by Jekke

  Reading about WPF and thinking about my application's data store at the same time led me to wonder if there are any languages or tools that allow you to define relational data in a declarative way? A shallow Google search suggests no such thing exists. Yet it seems so obviously useful. The kind of tool I have in mind would declaratively describe (at least) entities, relationships and views is a platform-agnostic way that would act as an abstraction layer between data-driven applications and their datastores. Does any such tool exist?

• Force import module from Python standard library instead of PYTHONPATH default

  - by jrdioko

  I have a custom module in one of the directories in my PYTHONPATH with the same name as one of the standard library modules, so that when I import module_name, that module gets loaded. If I want to use the original standard library module, is there any way to force Python to import from the standard library rather than from the PYTHONPATH directory, short of renaming the custom module and changing every reference to point to the new name?

• Something preventing default (explorer-style) CListCtrl jump to line behaviour

  - by andywebsdale

  I'm maintaining an MFC/COM/ATL 45-odd project solution originally written with VS6. I'm now using VS2008. I'm looking at a list control(vanilla CListCtrl) which doesn't behave as we think it should. Normally in an MFC list control you can press a key, (Q say) & selection will jump down to the 1st line beginning with 'Q' (like windows explorer). Does anyone have an idea as to why this might not happen? The styles/Extended styles are set the same as another control in the same project, which DOES work OK. Do I have to send my own message, or is there a flag, etc. that controls that functionality or what? Normally Google would supply the answer, but I haven't been able to frame my query correctly to come up with the relevant info this time. Here's the line from the .rc file for the CListCtrl that doesn't jump to a line on keypress: CONTROL "List1",IDC_BAL_LIST,"SysListView32",LVS_REPORT | LVS_SHOWSELALWAYS | WS_BORDER | WS_TABSTOP,0,73,493,230 And here's a line from the same .rc file showing a list control that does do that: CONTROL "List1",IDC_LIST1,"SysListView32",LVS_REPORT | LVS_SHOWSELALWAYS | WS_BORDER | WS_TABSTOP,1,38,501,219 As you can see, there's no obvious difference to the properties, so what program code would affect it?

• assembly language programming (prime number)

  - by chris

  Prompt the user for a positive three digit number, then read it. Let's call it N. Divide into N all integer values from 2 to (N/2)+1 and test to see if the division was even, in which case N is instantly shown to be non-prime. Output a message printing N and saying that it is not prime. If none of those integer values divide evenly (remainder never is zero), then N is shown to be prime. Output a message printing N and saying that it is prime. Ask the user if he or she wants to test another number; if the user types "n" or "N", quit. If "y" or "Y", jump back and repeat. Comments in your code are essential. Hi. I am kinda in rush to do this.. please help me doing it. I'll be much appreciated. thank you

• Is it possible to make notepad++ support tamil language functionality?

  - by pandiya chendur

  Notepad++ (from v2.3) supports the multilanguage functionality by means of a translated xml file (from english.xml). Normally you don't need it if you install Notepad++ by its installer. You may need the language file if you install Notepad++ from zip format binary (or if your language is not supported by NSIS installer). Is it possible to make notepad++ support tamil language functionality? If so,How to get started....
