• Advice on HTTPS connections using Ruby on Rails

  - by user502052

  Since I am developing a "secure" OAuth protocol for my RoR3 apps, I need to send protected information over the internet, so I need to use HTTPS connections (SSL/TSL). I read How to Cure Net::HTTP’s Risky Default HTTPS Behavior aticle that mentions the 'always_verify_ssl_certificates' gem, but, since I want to be more "pure" (it means: I do not want to install other gems, but I try to do everything with Ruby on Rails) as possible, I want to do that work without installing new gems. I read about 'open_uri' (it is also mentioned in the linked article: "open_uri is a common exception - it gets things right!") that is from the Ruby OOPL and I think it can do the same work. So, for my needs, is 'open_uri' the best choice (although it is more complicated of 'always_verify_ssl_certificates' gem)? If so, can someone help me using that (with an example, if possible) because I have not found good guides about?

• Python questions from beginner

  - by ChrisC

  I'm thinking about rewriting an MS Access db I wrote years ago into a stand-alone Python app. Other than a college class called "Intro to C++" (console only, with OOP concepts) and the Access db itself, I have no experience, so I need to ask if the basis for my decision to go with Python is correct. Is it true that: 1) Python is relatively easy to pick up? 2) Python apps can run as "portable" (ie from one directory, no registry needs, nothing needs to be pre-installed on a Windows PC) as long as I use an embedded db?

• Is there a J2SE sensor API?

  - by Martin Strandbygaard

  Does anyone know of a "standardized" Java API for working with sensors, and which is closely tied to J2ME as is the case with JSR 256? I'm writing a Java library for interfacing with a sensor network consisting of several different types of sensors (mostly simple stuff such as temperature, humidity, GPS, etc.). So far I've rolled my own interface, and users have to write apps against this. I would like to change this approach and implement a "standard" API so that implementations aren't that closely tied to my library. I've looked at JSR 256, but that really isn't a great solution as it's for J2ME, and my library is mostly used by Android devices or laptops running the full J2SE.

• Signing in to Twitter from iPhone - is the cake poisoned?

  - by Tristan

  Hi there, I'm using MGTwitterEngine to add Twitter functionality to my app. It's very easy to simply prompt the user for a username and password and then start posting. Strangely, however, I've noticed other apps (eg Foursquare and Brightkite) require you to visit their website to associate your Twitter account with your foursquare/brightkite/whatever account. Why do they do it this way? Is there a reason why my app shouldn't prompt the user for a Twitter username and password, even though it would be so easy? Thanks a bunch! Tristan

• How to casue a CppUnit test to fail - from C?

  - by mawg

  I'd like to have an equivalent to CPPUNIT_ASSERT, CPPUNIT_ASSERT_MESSAGE or `CPPUNIT_FAIL' which I can call from some common C code. Our code is a mix of C and C++. Some older apps and those with specific requirements are coded in C and most, especially newer, are coded in C++. However, a lot of project-agnostic, common code, such as memory buffer pools, debug tracing, etc are coded in C. When testing a C++ app in CppUnit, I'd to be able to sprinkle some ASSSERT()s which would cause any running CppUnit test to fail. Maye something like: if testing if running in debugger (Eclipse) then asm("int3"); // stop the debugger, even if no breakpoint at this line else if running CppUnit test - fail the test and move on to next else trace to log file Most of that can be run by wrapping a macro around a few #ifdefs, but I am not sure how I would cause a CppUni test to fail from C code. Can it be done?

• What is node.js?

  - by Jeffrey

  I don't fully get what node.js is all about. Maybe it's because I am mainly a web based business app developer. Can someone please explain what it is and the use of it? Thanks. My understanding so far is that: The programming model is event driven, especially the way it handles IO. It uses javascript and the parser is V8. It can be easily used to create concurrent server apps. Are my understandings correct? If yes, then what are the benefits of evented IO, is it just more for the concurrency stuffs? Also is the direction of node.js to become a framework like, javascript based (v8 based) programming model?

• LinearLayout of a WebView and a Button.

  - by Timmmm

  Hi, I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters: WebView: Height: wrap-content Weight: unset (by the way, what is the default?) Button: Height: wrap-content Weight: unset However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it. This is the one that works (copied from http://code.google.com/p/apps-for-android/source/browse/trunk/Samples/WebViewDemo/res/layout/main.xml): WebView: Height: 0 Weight: 1 Button: Height: wrap-content Weight: unset If you change any of those, e.g. give button a weight or change the WebView height to wrap-content then it doesn't work. My question is: Why? Can someone please explain what on Earth the android layout system is thinking?

• Hook Response.Cache to memcache

  - by dvr

  Has anyone done this before? I have a 32 bit win 2003 server running 2.0 and have read the ms engineers' blog about min(60%, 1800mb) for cache limits and our site (asp.net 2.0 / 3.5) is caching alot. It throws system outofmemory exceptions when wp is around 1.3gb (unfortunately it is the 2.0 apps) and I would like to push alot over to memcache but worried that at the moment the site is efficient using response.cache as is (though memory is an issue). I want to move most items over to memcache and have concerns on a – how to do this (implementation of response.cache to read/write from memcache) and b – what will performance be like? Before I commit to doing this and possibly spending a few days running tests I would like to hear from you if this has been done already and get some feedback. (and please don’t tell me to buy a x64 machine – I have already requested this!), by the way I ran a test requesting a single image 1000 times and response.cache was over 50% quicker than using application cache. Does response.cache bypass the page lifecycle?

• Django queries: Count number of objects with FK to model instance

  - by Chris Lawlor

  This should be easy but for some reason I'm having trouble finding it. I have the following: App(models.Model): ... Release(models.Model): date = models.DateTimeField() App = models.ForeignKey(App) ... How can I query for all App objects that have at least one Release? I started typing: App.objects.all().annotate(release_count=Count('??????')).filter(release_count__gt=0) Which won't work because Count doesn't span relationships, at least as far as I can tell. BONUS: Ultimately, I'd also like to be able to sort Apps by latest release date. I'm thinking of caching the latest release date in the app to make this a little easier (and cheaper), and updating it in the Release model's save method, unless of course there is a better way. Edit: I'm using Django 1.1 - not averse to migrating to dev in anticipation of 1.2 if there is a compelling reason though.

• Why is VB so popular? [closed]

  - by aaaidan

  To me, Visual Basic seems clumsy, ugly, error-prone, and difficult to read. I'll let others explain why. While VB.net has clearly been a huge leap forward for the language in terms of features, I still don't understand why anyone would choose to code in VB over, say, C#. However, I still see (what seems to be) the vast majority of commercial web apps from "MS shops" are built in VB. I could stand corrected on this, but VB still seems more popular than it deserves. Can anyone help answer any (or all) of these questions: Am I missing something with VB? Is it easier to learn, or "friendlier" than C#? Are there features I don't know about? Why is VB/VB.net so frequently used today, especially in web projects?

• iPad application submission with iPhone SDK beta 5 rejected

  - by FredM

  I try to send an specific iPad Application to iTunes connect before March 27 and as Apple says: "Only iPad apps compiled with iPhone SDK 3.2 beta 5 will be accepted for this initial review." So I compiled my application with iPhone SDK 3.2 beta 5 with a distribution provisioning profile. But when I upload my application on iTunes Connect, I have the following error: "The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application" For sure, it's the beta 5 ! Have you got an idea? Thank you in advance. Fred

• Tutorials for .NET database app

  - by ChrisC

  My earlier question and comments are at "What is ADO.NET". This shows my level of knowledge about c# database apps. Can someone point me to tutorials and/or primers that can help me proceed from where I am (also stated in other question)? I've looked and all I've found are tutorials that talk about general db basics (ie, not helping with VS/C#), or talk about connecting to existing SQL db's. I need help setting one up and configuring it, as well as help on how to create and use queries to test the db schema.

• Open source alternative to WebEx WebOffice?

  - by Dieseltime

  I have a client who has been using WebOffice (from WebEx) for a variety of tasks within their small organization. The problem is that they only really need a small subset of the features WebOffice provides (Contact list, Database, and Document Storage). They've asked me to develop a website focused on these three features with the rationalization that this should be more cost-effective, since they currently aren't using many of the features of WebOffice they pay for. What are some open-source alternatives that I could implement for them? Sharepoint sounds like it would be too bloated and Google Apps may not be as collaborative as they would like.

• Best practices for developing bigger applications on Android

  - by Janusz

  I've already written some small Android Applications, most of them in one Activity and nearly no data that should be persistent on the device. Now I'm writing an application that needs more Activities and I'm a bit puzzled about how to organize all this. My app will download some data parse it show it to the user and then show other activities depending on the data and the user interaction. Some of that data could be cached, some of it has to be downloaded every time. Some of that data should not be downloaded freshly at the moment the orientation changes, but it should on the moment the activity is created... Another thing I'm confused about are things like a httpClient. I now for example create a new httpclient for every activity, the same thing for locationlisteners. Are there books, a blogs or documentations with patterns, examples and advice on organizing larger apps build on android? Everything I found until now are get startet tutorials leaving me alone after 60 lines of code...

• Test Application Guide for Winforms

  - by Jonathan

  I'm a c# developer in a medium/small company. I use to do quick test of the apps that my workmates made and they use to test my applications. We test each form based in our experience. (yes, I know this is not a very formal method) Now a new guy without experience are going to join our team. We think now is the momento to make a little list of things that all we should test in each form. Divided by categories. For example usability: Test that the taborder of each control are properly setted, or Valitacion: Test that the max lenght of each textbox match with the max lenght of a field in the DB...etc We don't one to Reinvent the Wheels, so I want to know if such kind of document already exists. Thanks

• Oracle vocabulary, what is the mysql/SQL Server equivalent of a database

  - by jeph perro

  Hi, I need some help with vocabulary, I don't use Oracle that often but I am familiar with MySQL and SQL Server. I have an application I need to upgrade and migrate, and part of the procedure to do that involves exporting to an XML file, allowing the installer to create new database tables, then import to the new database tables from the XML file. In Oracle, my database connection specifies a username, password, and an SID. Let's call the SID, "COMPANY-APPS". This SID contains tables belonging to several applications, each of which connects with a different user ( "WIKIUSER", "BUGUSER", "TIMETRACKERUSER" ). My question is: Can I re-use the same user to create the new tables ( with the same names ). In MySQL or SQL Server, I would create a new database and grant my user privileges to create tables in it. OR, do I need to create a new database user for my upgraded tables?

• Compiling python modules whith DEBUG defined on MSVC

  - by DaedalusFall

  Python rather stupidly has a pragma directive in its include files that forces a link against python26_d.lib when the DEBUG preprocessor variable is defined. This is a problem because the python installer doesn't come with python26_d.lib! So I can't build applications in msvc in debug mode. If i temporarily #undef DEBUG for just one file I get many complaints about inconsistent DLL linkage. If I change the pragma in pythons include file I get undefined references to various debug functions. I have tried compiling my own version of python but its somehow different enough from the python that gets distributed that I can't use my modules with apps built with the vanilla version of python Can anyone give me any advice on how to get round this? Thanks

• iphone OS 3.1.3 requires snow leopard upgrade

  - by unsorted

  itunes asked me to upgrade my iphone's OS to 3.1.3, so I complied naively. then xcode told me that the latest iphone OS version it could support was 3.1.2. So I went to download a new version from https://developer.apple.com/iphone/index.action#downloads, xcode 3.2.2 with iphone SDK. but when i went to install that, i was told I needed snow leopard 10.6.2 or later. so I'm just making sure that I am not misinterpreting anything when I say that, given that it is impossible to downgrade iphone OS versions without jailbreaking, I need to install a new version of the OS just so I can resume testing apps on my iphone?

• Building a Universal iPad App - Where is the device recognition code?

  - by JustinXXVII

  I noticed that when I create a new project in XCode for a Universal iPad/iPhone application, the template comes with two separate App Delegate files, one for each device. I can't seem to locate the place in code where it tries to decide which app delegate to use. I have an existing iPhone project I'd like to port to iPad. My thinking was that if I went ahead and designed the iPad project, I could just import my iPhone classes and nibs, and then use the App Delegate and UIDevice to decide which MainWindow.xib to load. The process went like this: Create an iPad project coded as a split-view create brand new classes and nibs for the iPad import iPhone classes and nibs Change build/target settings in accordance with Universal Apps Use [[UIDevice currentDevice] model] in the AppDelegate to decide which MainWindow to load Will this work, or does the app just automatically know which device it's being deployed on? Thanks for any insight you can offer.
