• Anunciando Windows Azure Mobile Services (Serviços Móveis da Windows Azure)

  - by Leniel Macaferi

  Estou animado para anunciar uma nova capacidade que estamos adicionando à Windows Azure hoje: Windows Azure Mobile Services (Serviços Móveis da Windows Azure) Os Serviços Móveis da Windows Azure tornam incrivelmente fácil conectar um backend da nuvem escalável em suas aplicações clientes e móveis. Estes serviços permitem que você facilmente armazene dados estruturados na nuvem que podem abranger dispositivos e usuários, integrando tais dados com autenticação do usuário. Você também pode enviar atualizações para os clientes através de notificações push. O lançamento de hoje permite que você adicione essas capacidades em qualquer aplicação Windows 8 em literalmente minutos, e fornece uma maneira super produtiva para que você transforme rapidamente suas ideias em aplicações. Também vamos adicionar suporte para permitir esses mesmos cenários para o Windows Phone, iOS e dispositivos Android em breve. Leia este tutorial inicial (em Inglês) que mostra como você pode construir (em menos de 5 minutos) uma simples aplicação Windows 8 "Todo List" (Lista de Tarefas) que é habilitada para a nuvem usando os Serviços Móveis da Windows Azure. Ou assista este vídeo (em Inglês) onde mostro como construí-la passo a passo. Começando Se você ainda não possui uma conta na Windows Azure, você pode se inscrever usando uma assinatura gratuita sem compromisso. Uma vez inscrito, clique na seção "preview features" logo abaixo da tab "account" (conta) no website www.windowsazure.com e ative sua conta para ter acesso ao preview dos "Mobile Services" (Serviços Móveis). Instruções sobre como ativar estes novos recursos podem ser encontradas aqui (em Inglês). Depois de habilitar os Serviços Móveis, entre no Portal da Windows Azure, clique no botão "New" (Novo) e escolha o novo ícone "Mobile Services" (Serviços Móveis) para criar o seu primeiro backend móvel. Uma vez criado, você verá uma página de início rápido como a mostrada a seguir com instruções sobre como conectar o seu serviço móvel a uma aplicação Windows 8 cliente já existente, a qual você já tenha começado a implementar, ou como criar e conectar uma nova aplicação Windows 8 cliente ao backend móvel: Leia este tutorial inicial (em Inglês) com explicações passo a passo sobre como construir (em menos de 5 minutos) uma simples aplicação Windows 8 "Todo List" (Lista de Tarefas) que armazena os dados na Windows Azure. Armazenamento Dados na Nuvem Armazenar dados na nuvem com os Serviços Móveis da Windows Azure é incrivelmente fácil. Quando você cria um Serviço Móvel da Windows Azure, nós automaticamente o associamos com um banco de dados SQL dentro da Windows Azure. O backend do Serviço Móvel da Windows Azure então fornece suporte nativo para permitir que aplicações remotas armazenem e recuperem dados com segurança através dele (usando end-points REST seguros, através de um formato OData baseado em JSON) - sem que você tenha que escrever ou implantar qualquer código personalizado no servidor. Suporte integrado para o gerenciamento do backend é fornecido dentro do Portal da Windows Azure para a criação de novas tabelas, navegação pelos dados, criação de índices, e controle de permissões de acesso. Isto torna incrivelmente fácil conectar aplicações clientes na nuvem, e permite que os desenvolvedores de aplicações desktop que não têm muito conhecimento sobre código que roda no servidor sejam produtivos desde o início. Eles podem se concentrar na construção da experiência da aplicação cliente, tirando vantagem dos Serviços Móveis da Windows Azure para fornecer os serviços de backend da nuvem que se façam necessários.  A seguir está um exemplo de código Windows 8 C#/XAML do lado do cliente que poderia ser usado para consultar os dados de um Serviço Móvel da Windows Azure. Desenvolvedores de aplicações que rodam no cliente e que usam C# podem escrever consultas como esta usando LINQ e objetos fortemente tipados POCO, os quais serão mais tarde traduzidos em consultas HTTP REST que são executadas em um Serviço Móvel da Windows Azure. Os desenvolvedores não precisam escrever ou implantar qualquer código personalizado no lado do servidor para permitir que o código do lado do cliente mostrado a seguir seja executado de forma assíncrona preenchendo a interface (UI) do cliente: Como os Serviços Móveis fazem parte da Windows Azure, os desenvolvedores podem escolher mais tarde se querem aumentar ou estender sua solução adicionando funcionalidades no lado do servidor bem como lógica de negócio mais avançada, se quiserem. Isso proporciona o máximo de flexibilidade, e permite que os desenvolvedores ampliem suas soluções para atender qualquer necessidade. Autenticação do Usuário e Notificações Push Os Serviços Móveis da Windows Azure também tornam incrivelmente fácil integrar autenticação/autorização de usuários e notificações push em suas aplicações. Você pode usar esses recursos para habilitar autenticação e controlar as permissões de acesso aos dados que você armazena na nuvem de uma maneira granular. Você também pode enviar notificações push para os usuários/dispositivos quando os dados são alterados. Os Serviços Móveis da Windows Azure suportam o conceito de "scripts do servidor" (pequenos pedaços de script que são executados no servidor em resposta a ações), os quais tornam a habilitação desses cenários muito fácil. A seguir estão links para alguns tutoriais (em Inglês) no formato passo a passo para cenários comuns de autenticação/autorização/push que você pode utilizar com os Serviços Móveis da Windows Azure e aplicações Windows 8: Habilitando Autenticação do Usuário Autorizando Usuários  Começando com Push Notifications Push Notifications para múltiplos Usuários Gerencie e Monitore seu Serviço Móvel Assim como todos os outros serviços na Windows Azure, você pode monitorar o uso e as métricas do backend de seu Serviço Móvel usando a tab "Dashboard" dentro do Portal da Windows Azure. A tab Dashboard fornece uma visão de monitoramento que mostra as chamadas de API, largura de banda e ciclos de CPU do servidor consumidos pelo seu Serviço Móvel da Windows Azure. Você também usar a tab "Logs" dentro do portal para ver mensagens de erro.  Isto torna fácil monitorar e controlar como sua aplicação está funcionando. Aumente a Capacidade de acordo com o Crescimento do Seu Negócio Os Serviços Móveis da Windows Azure agora permitem que cada cliente da Windows Azure crie e execute até 10 Serviços Móveis de forma gratuita, em um ambiente de hospedagem compartilhado com múltiplos banco de dados (onde o backend do seu Serviço Móvel será um dos vários aplicativos sendo executados em um conjunto compartilhado de recursos do servidor). Isso fornece uma maneira fácil de começar a implementar seus projetos sem nenhum custo algum (nota: cada conta gratuita da Windows Azure também inclui um banco de dados SQL de 1GB que você pode usar com qualquer número de aplicações ou Serviços Móveis da Windows Azure). Se sua aplicação cliente se tornar popular, você pode clicar na tab "Scale" (Aumentar Capacidade) do seu Serviço Móvel e mudar de "Shared" (Compartilhado) para o modo "Reserved" (Reservado). Isso permite que você possa isolar suas aplicações de maneira que você seja o único cliente dentro de uma máquina virtual. Isso permite que você dimensione elasticamente a quantidade de recursos que suas aplicações consomem - permitindo que você aumente (ou diminua) sua capacidade de acordo com o tráfego de dados: Com a Windows Azure você paga por capacidade de processamento por hora - o que te permite dimensionar para cima e para baixo seus recursos para atender apenas o que você precisa. Isso permite um modelo super flexível que é ideal para novos cenários de aplicações móveis, bem como para novas empresas que estão apenas começando. Resumo Eu só toquei na superfície do que você pode fazer com os Serviços Móveis da Windows Azure - há muito mais recursos para explorar. Com os Serviços Móveis da Windows Azure, você será capaz de construir cenários de aplicações móveis mais rápido do que nunca, permitindo experiências de usuário ainda melhores - conectando suas aplicações clientes na nuvem. Visite o centro de desenvolvimento dos Serviços Móveis da Windows Azure (em Inglês) para aprender mais, e construa sua primeira aplicação Windows 8 conectada à Windows Azure hoje. E leia este tutorial inicial (em Inglês) com explicações passo a passo que mostram como você pode construir (em menos de 5 minutos) uma simples aplicação Windows 8 "Todo List" (Lista de Tarefas) habilitada para a nuvem usando os Serviços Móveis da Windows Azure. Espero que ajude, - Scott P.S. Além do blog, eu também estou utilizando o Twitter para atualizações rápidas e para compartilhar links.

• What's the Benefit of Multiple Monitors

  - by DaveDev

  It's become apparent to me that in Software Development it's not uncommon to have more than 1 monitor. We've been pushing for multiple monitors here (currently I have 1 19") but it's difficult to get the point across to the 'deciders' that there would be a benefit. They're only concerned with saving cents. So I thought I'd ask around and see what software developers with multiple monitors thought? What are the benefits? What are the costs? What is the ideal number of monitors for a software developer? Thanks

• ETL Tools and Build Tools

  - by Ngu Soon Hui

  I have familiarities with software automated build tools ( such as Automated Build Studio). Now I am looking at ETL tools. The one thing crosses my mind is that, I can do anything I can do in ETL tools by using a software build tool. ETL tools are tailored for data loading and manipulation for which a lot of scripts are needed in order to do the job. Software build tool, on the other hand, is versatile enough to do any jobs, including writing scripts to extract, transform and load any data from any format into any format. Am I right?

• What documentation is helpful when supporting an application?

  - by Andrew

  I am going to be taking over from a developer here at work soon. Hence, I'll be supporting all the applications that he has written over the last few years. My question is, when supporting an application that you probably don't know much about, what kind of documentation is most helpful to get a handle on how to fix problems, extend functionality, modify functionality, etc? I'm thinking it would need to give you an overview of what the software does, what interfaces it has to other software, what databases it uses, usernames, passwords, and so on. Is there such a thing as a software support document? Referrals to any templates would be most helpful. BTW, unfortunately, there are no requirements documents, specs, etc! So, really my question is, if my colleague had a day to write a single document for each application so that I could (more easily) support it, what would that document be and/or what would it look like?

• Starting point for learning CAD/CAE file formats?

  - by Escader

  We are developing some stress and strain analysis software at university. Now it's time to move from rectangles and boxes and spheres to some real models. But I still have little idea where to start. In our software we are going to build mesh and then make calculations, but how do I import solid bodies from CAD/CAE software? 1) How CAD/CAE models are organised? How solid bodies are represented? What are the possibilities of DWG, DXF, IGES, STEP formats? There is e.g. a complete DXF reference, but it's too difficult for me to understand without knowing basic concepts. 2) Are there C++ libraries to import solid bodies from CAD/CAE file formats? Won't it be too difficult to build a complete model to be able to import comprehensive file?

• MySQL full text search with partial words

  - by Rob

  MySQL Full Text searching appears to be great and the best way to search in SQL. However, I seem to be stuck on the fact that it won't search partial words. For instance if I have an article titled "MySQL Tutorial" and search for "MySQL", it won't find it. Having done some searching I found various references to support for this coming in MySQL 4 (i'm using 5.1.40). I've tried using "MySQL" and "%MySQL%", but neither works (one link I found suggested it was stars but you could only do it at the end or the beginning not both). Here's my table structure and my query, if someone could tell me where i'm going wrong that would be great. I'm assuming partial word matching is built in somehow. CREATE TABLE IF NOT EXISTS `articles` ( `article_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT, `article_name` varchar(64) NOT NULL, `article_desc` text NOT NULL, `article_link` varchar(128) NOT NULL, `article_hits` int(11) NOT NULL, `article_user_hits` int(7) unsigned NOT NULL DEFAULT '0', `article_guest_hits` int(10) unsigned NOT NULL DEFAULT '0', `article_rating` decimal(4,2) NOT NULL DEFAULT '0.00', `article_site_id` smallint(5) unsigned NOT NULL DEFAULT '0', `article_time_added` int(10) unsigned NOT NULL, `article_discussion_id` smallint(5) unsigned NOT NULL DEFAULT '0', `article_source_type` varchar(12) NOT NULL, `article_source_value` varchar(12) NOT NULL, PRIMARY KEY (`article_id`), FULLTEXT KEY `article_name` (`article_name`,`article_desc`,`article_link`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ; INSERT INTO `articles` VALUES (1, 'MySQL Tutorial', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.

• How can I differentiate between the .net WebBrowser component and an actual browser?

  - by Septih

  OK, so we have an online downloads store accessed via our software. Recently we've had requests to allow downloads via normal browsers and it's fairly easy just to slap a download page on. The problem is that it would be confusing to people having two download links, one for the software and one for their web browser, so we want to differentiate between the two and only show the relevant download link. From what I've gathered, the .net WebBrowser component is the same as IE and uses the same User Agent, so we can't use that unless we subclass the WebBrowser in the software to make it use a specific User Agent. It's the more sensible option, but we'd have to roll out another updated version, which is less than ideal. Are there any other ways to tell if someone's accessing a site via the .net component? My only other alternative is to copy the store to a different address with the different download links and send people there. Again this is doable, but not ideal.

• Microsoft Quotation

  - by Asad Jibran Ahmed

  I don't know if this is the right place to ask this question, but I honestly have exhausted my self searching for the last hour. I am looking for a quotation made about Microsofts software. It goes something along the lines of: "They may make 2nd grade crappy software, but by God they know how to design interfaces" It was by a somewhat popular open source personality about the lack of good interface design in open source software. Does any one know the exact quotation? It will be a great help if someone can point me in the right direction.

• iTunes Visualization -- What type of code is it written in and what does that code look like?

  - by Christopher Altman

  Being a web developer, I know how event driven user interfaces are written, but do not have insight into other families of code (embedded software like automotive software, automation software on assembly lines, drivers, or the crawling lower-thirds on CNN, etc.) I was looking at the iTunes visualizer (example) and am curious: What code is used to write the visualizer? Objective C? Does it use Core Animation? What type of abstraction does that library offer? What does the code look like? Is it a list of mathematical equations for producing the crazy graphics? Is it a list of key frames with tweening? Is there an array of images, fractals, worm holes, flowers, sparkles, and some magic mixes them together. Or something totally different? I am not looking for a tutorial, just an understanding of how something very different than web development works. Oh yah, I know iTunes is closed source, so all of this is conjecture.

• Selecting the most common value from relation - SQL statement

  - by Ronnie

  I have a table within my database that has many records, some records share the same value for one of the columns. e.g. | id | name | software | ______________________________ | 1 | john | photoshop | | 2 | paul | photoshop | | 3 | gary | textmate | | 4 | ade | fireworks | | 5 | fred | textmate | | 6 | bob | photoshop | I would like to return the value of the most common occurring piece of software, by using an SQL statement. So in the example above the required SQL statement would return 'photoshop' as it occurs more than any other piece of software. Is this possible? Thank you for your time.

• Exceptions & Interrupts

  - by Betamoo

  When I was searching for a distinction between Exceptions and Interrupts, I found this question Interrupts and exceptions on SO... Some answers there were not suitable (at least for assembly level): "Exception are software-version of an interrupt" But there exist software interrupts!! "Interrupts are asynchronous but exceptions are synchronous" Is that right? "Interrupts occur regularly" "Interrupts are hardware implemented trap, exceptions are software implemented" Same as above! I need to find if some of these answers were right , also I would be grateful if anyone could provide a better answer... Thanks!

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers What other items are missing from the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) Try to think about where you, a software developer, would expect to find the information by browsing (not searching). A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical.

• Open source project home page

  - by Oskar Kjellin

  I've created a software that I want to be able to market. I'd like to be able to post it on forums etc and for that I need a home page. Is there any open source C# project home pages that you can use? The functionality I'm looking for is like adding new versions (perhaps a version control from the software), downloading and user guides. So what I want is pretty basic: I want to be able to upload and let the users download. I've written this on my own as well but I guess that if there are open source projects that have done this they're probably better. This can't be such a rare problem so please lead me to some resources so that I can create my page and publish my software! :)

• Does there exist an "idea checkout system" on the Internet?

  - by TimeSpace Traveller

  Greetings. I would like to ask the following question: is there anything on the Internet like an "idea checkout" system? Situation: I'm a software developer. Since my current job has started 2 years ago, my mentor at that time has pointed me to the open source world. I have only put little time to look at some of the open source projects, let alone any contribution. However, it is my wish to start developing something outside of the work. Well, except a little problem. I don't know what to develop! It is not about the technical knowledge; the problem is that, I am not a creative person. I am very good at analytical thinking, as well as debugging skills. When being told by my work partners to develop a solution, I could get it done without a problem. However, outside of work, I have no idea what to develop. When I look at the Internet, it seems that so many people have already been developing on so many interesting stuff, making me wonder what I could develop, so that I would not reinvent something already existed. That starts to make me wonder. On the Internet, is there anything like an "idea checkout" system or society? For example, some people would throw in as a software idea, and the system would keep it as an "inventory"; later, a potential software developer would "check out" the idea, just a how people would check out a book from the library. Then, the developer would check the "idea" back in, with a certain kind of work-in-progress or developed software, thus becoming an open-source project. I have just noticed that here at stackoverflow, there is a "Project-Ideas" tag, so perhaps that can provide me some ideas on what to develop; still, my wonder is about a system that people would provide ideas, and people would check out ideas to develop / implement into actual solution. Is there such a system or society existing anywhere on the Internet? Any input is welcome! Thank you very much. Update: Thank you for everyone who has answered my question. Certainly, "getting idea" is part of my problem; as a software developer, however, I'm concerned more than just "getting idea". What I am concerned more, as I have commented, is about the existence of such an idea exchanging ecosystem, capable to initiate open-source projects. I'll put an example here. Say, person A has an idea of music search program, but not search by the attributes of the music (composer, singer, publisher, lyrics, etc.); instead, he wants a program (and a database) to search a piece of music by melody. Very often, people only remember a piece of music by its melody, not even the name of the music (e.g. the music he wants was only once heard in a bookstore, but the melody just gets stuck in his head!). In order to find that piece, normally he would just need to blindly search for it, and spent a long time to do so. A search by melody would enable person A to find the piece much quicker. However, he would not want to personally work on it, not just because of the complexity (he is not a musician and/or programmer, knowing almost nothing about music systems in computer, search algorithms, etc.), but also legal issues (RIAA??), thus he would just like to keep the idea at some place, and let other people to work on that. Now, a developer (person B) may be at the same stage as I am right now, wishing to find something to develop, but not having an idea. With the idea exchanging ecosystem, person B will search, and somehow discover person A's music search idea, and feeling interested enough to work on it. So he "checks out" the idea, start working on it (at least a skeleton), and checks back in with the progress. An open-source project starts from here, fulfilling person A's wish, and person B's programming desire. The above is just an example, because there are already such systems exist on the Internet, but it illustrates what I think about the idea exchange system in my mind. My main concern is about idea exchanging ecosystem, not at personal and unorganized level, but at a semi-organized protocol that's specifically for software developers, having actual projects coming out as the fruits. Not about "projects", but about "ideas and product of ideas". Hopefully that would clear up some of the original idea of this question. Any input is welcome; in fact, I would like to hear as many people as possible how everyone thinks about this. Thank you very much!

• Migrating from SQL Server to firebird: pro and cons

  - by user193655

  I am considering the migration for 4 reasons: 1) SQLSERVER installation is a nightmare, expecially for 1-user software (Even if typically I have 3-20 users, sometimes I sell my software to single users: it is incredible to have troubles installing the DB, while installing the applicatino means copying an exe...). (note my max installation is 100 users, but there is no an upper limit). Software installs in 10 seconds, SQLServer in 1 hour. Firebird installation is much easier. 2) SQLSERVER runs on windows server only 3) My customers have all the express edition 4) i am not using any advanced feature, I am now starting using filestream, but the main reason for this is that Express edition has 4/10GB db size limit So these are all Pros of moving to Firebird. Which are the cons? I can also plan to support both platforms, but this will backfire I fear.

• handle user logoff or machine shutdown requests on WindowsME

  - by skylap

  I have to write a C# application that runs on WindowsME. Yes, I mean that Microsoft operating system that has been forgotten a long long time ago. My program needs no user interaction and as WindowsME doesn't support services, it will be a console application. Furthermore it will be used on more modern operating systems, where the user can choose whether to start it as console application or install it as a windows service. Now suppose the software is running on WinME and the user decides to logoff or shutdown the machine without a prior quit of my software. WinME complains about my program still running and asks if it should kill the process. Apart from the bad user experiance, this means that the application is not shut down properly. So I look for a way to be informed if the user logs off or wants to shutdown the machine to be able to perform a proper shutdown of my software first.

• Super user powers in development environment?

  - by red tiger

  Is it too much to ask for when I ask the IT department to give my development team an environment where we can use whatever software that we can download without having to have security check those tools? Of course, the software can be checked by security before deploying to Test, and the development environment can be on a VLAN that is not accessible from outside. This would greatly aid us by allowing us to use whatever open-source testing tools that we want. I'm asking because we have such tight restrictions on the software approval process, and I hear of other teams that have an environment where they can configure their local server however they want and they can use whatever tools they want. What's the norm out there? Thank you for any comments!

• ActiveX communication

  - by Mario Marinato -br-

  I'm developing an ActiveX EXE that exposes an specific class to a third-party software. This third-party software instanciates an object of this class and uses its methods. Strangely, this third-party software destroys its object of my exposed class as soon as it calls an specific method, but I have no idea why this happens. The only clue I have is that this method is the only one that returns a value. All the other ones are simple 'subs' that do not return any value, and when they are called nothing wrong happens. I'm using VB6. Do you guys have any idea of why it's happening?

• Defining - and dealing with - Evil

  - by Chris Becke

  As a software developer one sometimes gets feature requests that seem to be in some kind of morally grey area. Sometimes one can deflect them, or implement them in a way that feels less 'evil' - sometimes - on reflection - while the feature request 'feels' wrong theres no identifiable part of it that actually causes harm. Sometimes one feels a feature is totally innocent but various anti virus products start tagging one as malware. For example - I personally consider EULAs to (a) hopefully be unenforceable and (b) a means by which rights are REMOVED from consumers. However Anti Virus scanners frequently mark as malware any kind of download agent that does not display a EULA. Which to me is the result of a curious kind of double think. What I want to know is - are there any online (or offline) resources that cover evil software development practices? How can I know if a software practice that I consider dodgy is in fact evil enough to consider fighting?

  If I was writing a piece of software that attempted to predict what word a user was going to type next using the two previous words the user had typed, I would create two tables. Like so: == 1-gram table == Token | NextWord | Frequency ------+----------+----------- "I" | "like" | 15 "I" | "hate" | 20 == 2-gram table == Token | NextWord | Frequency ---------+------------+----------- "I like" | "apples" | 8 "I like" | "tomatoes" | 12 "I hate" | "tomatoes" | 20 "I hate" | "apples" | 2 Following this example implimentation the user types "I" and the software, using the above database, predicts that the next word the user is going to type is "hate". If the user does type "hate" then the software will then predict that the next word the user is going to type is "tomatoes". However, this implimentation would require a table for each additional n-gram that I choose to take into account. If I decided that I wanted to take the 5 or 6 preceding words into account when predicting the next word, then I would need 5-6 tables, and an exponentially increase in space per n-gram. What would be the best way to represent this in only one or two tables, that has no upper-limit on the number of n-grams I can support?

• Control Philips Living Colors using PC

  - by CrazyChris

  Hi guys, is there a way (hardware/software-combination) that I can use to control one or more "Philips Living Colors" lamps using a PC - e.g. a USB-stick that acts as the "remote". This way i could control the lamp through software (e.g. a web-app - over iPhone / remotely) or even create what Philips builds into some of their TVs and calls "ambilight" (graphics driver detecting the main color to control the lamp). I guess this is more like a hardware than a software question - but I couldn't find anything about this online and I'm sure not to be the first to have come up with this idea right when I unpacked my LivingColors lamp yesterday ;) Any idea/hint is appreciated. -chris

• How RSS feed submitter softwares are able to submit feeds??

  - by Nok Imchen

  Well, recently i bought a software that submits RSS to various RSS directories. Some of the directories, when we visit manually through a internet browser, requires registrations to submit our feed (Most popular example of such directories is feedage dot com) What made me wonder is, the software don't ask any login details while submitting my feed to 'feedage'!!! Now, what i'd like to know is, how the software is able to submit my feed to feedage without loggin in ?? if i can get the procedure then i'm planning to code a php script that will do the work for me from my server using cron job

• Can't find AVD or SDK manager in Eclipse

  - by zigzag

  Seems like I'm having some problems after updating my android sdk tools and platform-tools using the sdk manager. The problem is that, after updating, I found that the avd or sdk options in the windows dropdown menu in eclipse are gone! And, I can't find any option to create an android project from file-new projects any more. I tried removing the ADT from eclipse and the software site "https://dl-ssl.google.com/android/eclipse/" from "available software sites" and then reinstalled the ADT from "https://dl-ssl.google.com/android/eclipse/" using help-install new software. The installation was successful, but I still don't have any option for shortcuts to the SDK manager or the AVD in eclipse, and neither can I create a new android project. By the way, the android perspectives are not gone, they are still here. Also, I can manually open the avd and sdk manager from the directory where I have installed them. Can anyone please show me a workaround? Any help would be greatly appreciated.

• PyQt4 Need to move DLLs to package root

  - by Xavier

  Hi Guys, I've used the new installers from http://www.riverbankcomputing.co.uk/software/pyqt/download for Python 2.6 x86_64 and I've a small problem importing PyQt4 in one particular application. Here's the traceback: # ERROR : Traceback (most recent call last): # File "<Script Block >", line 2, in <module> # from PyQt4 import QtCore # ImportError: DLL load failed: The specified procedure could not be found. # - [line 2] This might look familiar. Fun thing is that in a previous version of the 3d software it does work (and from a standard command line), but not in the new software version. I inspected the sys.path (within the app) in order to see if this path was there: C:\Python26\Lib\site-packages\PyQt4\bin In both application this path is present. Finally managed to make it works by copying the DLLs from C:\Python26\Lib\site-packages\PyQt4\bin to C:\Python26\Lib\site-packages\PyQt4 Is there any known reason for this? I've a hard time debugging this thing further (making sure everything is 64 bit, path are correct, etc) Thanks for your help
