  • What is the best unit test framework for .NET and why?

    - by rmx
    It seems to me that everyone uses NUnit without even considering the other options. I think this is because: Everyone is familiar with it already so they won't have to learn a new API. It is already set up with their continuous integration server to work with NUnit. Am I wrong about this? I decided to use xUnit on one of my own projects recently and I love it! It makes so much more sense to me and conceptually it seems like a definite step forward from NUnit. I'd like to hear opinions on which framework is actually the best - not taking into consideration having to learn it or reconfigure your automated testing.

  • Getting the front buffer into a gfx mem surface (Dx9)

    - by lapin
    I'm using DirectX 9 to acquire the frontbuffer. There are a couple of ways I know of to get at the front buffer: GetRenderTargetData() GetFrontBufferData() The MSDN page on both of these API calls state that the data is copied from device memory to system memory. I'd like to copy the front buffer surface directly to another graphics memory surface, as I have other manipulations to perform on the acquired surface before returning it to system memory. I'm creating a D3DUSAGE_DYNAMIC texture (gfx mem texture) and calling GetFrontBufferData() to write the front buffer to my textures surface0. Is this valid? Will the operation remain in gfx memory, or will it need to move to system memory and then back to graphics memory? If this is the case, is what I'm trying to achieve possible?

  • Consolidating hotels data from various booking sites with different IDs or reference

    - by Victor
    In one of my projects, I have data for hotels, and other booking sites are able to book this hotel. For example: Hotel A - Booking (ID = 4002), Expedia (ID = 123), Priceline (ID = 147) The three booking engines each uses their own Id to reference to Hotel A. I would need to check manually and make the right reference to the hotel. If I have 100,000 hotels, I have to check manually 300,000 (considering 3 booking sites) times? They might provide API, then I can cross check the name, address or latitude/longitude, but if they differ a little bit then I might give the wrong reference to the wrong hotel. I'm sure there are better ways to do this. There are many travel sites out there which do hotel price checking on many booking sites, but how do they do to make sure they are checking the right hotel on these booking sites? Anyone has any experience on this?

  • Windows 8 : Microsoft veut supporter plus de langages dans WinRT, les objectifs de la firme dévoilés lors de Lang.NEXT

    Windows 8 : Microsoft veut supporter plus de langages dans WinRT en plus de ceux existants Microsoft a décidé d'introduire, pour Windows 8 (son futur système d'exploitation pour PC et tablettes), une nouvelle couche pour le développement d'applications. WinRT (Windows Runtine) propose de nouvelles API pour la conception des applications de style Metro. La plateforme supporte plusieurs langages, dont XAML pour la conception de l'interface utilisateur, associé à C#, VB.NET ou C++, ainsi que HTML5, JavaScript et CSS. Lors de la conférence Lang.Next qui s'est tenue cette semaine, Microsoft a essentiellement porté son attention sur WinRT et a répondu à plusieurs inquiétudes qu...

  • Java Phones: How to set up JTAPI?

    - by Adam Tannon
    I want to use JTAPI (1.4 - latest) to create an app that will call my phone whenever I need it to. I downloaded JSR043 (JTAPI specification) and have been reading the API docs and it seems pretty straight forward with respect to how to code JTAPI. However I seriously doubt that getting a Java app on my laptop to call my cell phone doesn't require some 3rd party or middle man service provider and possibly other entities/configurations as well. So I ask: besides using the JTAPI in my Java code, what do I need to install or set up to have a Java app that calls my phone? Thanks in advance!

  • Linux Programmer moving to Windows

    - by cytinus
    I am a fairly proficient Linux programmer. I have been coding in Linux for 4 years, for both personal reasons and for profit. During those 4 years I have not even owned a computer running the Windows operating system. I am looking to expand my horizons into Windows programming, but am finding myself overwhelmed with the lack of what I perceive to be standardization. I feel as though different compilers follow different conventions, and all of the worthwhile IDEs cost money. Whats worse is that so many of the Tutorials are just terrible. If anyone else has taken the switch from Linux to Windows programming, what was the most helpful. What are the most straightforward IDEs and tutorials for using the API. I am looking to do mainly C and C++ development, along with some x86. I have found MASM primarily suits my needs for the latter.

  • Useful design patterns for working with FragmentManager on Android

    - by antman8969
    When working with fragments, I have been using a class composed of static methods that define actions on fragments. For any given project, I might have a class called FragmentActions, which contains methods similar to the following: public static void showDeviceFragment(FragmentManager man){ String tag = AllDevicesFragment.getFragmentTag(); AllDevicesFragment fragment = (AllDevicesFragment)man.findFragmentByTag(tag); if(fragment == null){ fragment = new AllDevicesFragment(); } FragmentTransaction t = man.beginTransaction(); t.add(R.id.main_frame, fragment, tag); t.commit(); } I'll usually have one method per application screen. I do something like this when I work with small local databases (usually SQLite) so I applied it to fragments, which seem to have a similar workflow; I'm not married to it though. How have you organized your applications to interface with the Fragments API, and what (if any) design patterns do you think apply do this?

  • Getting data from a webpage in a stable and efficient way

    - by Mike Heremans
    Recently I've learned that using a regex to parse the HTML of a website to get the data you need isn't the best course of action. So my question is simple: What then, is the best / most efficient and a generally stable way to get this data? I should note that: There are no API's There is no other source where I can get the data from (no databases, feeds and such) There is no access to the source files. (Data from public websites) Let's say the data is normal text, displayed in a table in a html page I'm currently using python for my project but a language independent solution/tips would be nice. As a side question: How would you go about it when the webpage is constructed by Ajax calls?

  • lighter-weight (semantic) scuttle

    - by hroptatyr
    Before patching scuttle or semanticscuttle I thought I'd ask if anyone knows of a lighter-weight/faster system to tag bookmarks and vote on them? LAMP is fine. Ideally, I should be allowed to interfere with the database directly. My actual problem is I want to administer roughly 80m bookmarks, tag them, vote on them (it's just 10 users accessing the system), but here's the thing: All of those bookmarks will change their descriptions (and title lines) at least once a day. Both systems support the del.icio.us API but my LAMP stack is unable to cope with the load.

  • How to run ubuntu-tweak's janitor automatically?

    - by Eliran Malka
    My aim is to have the janitor running at startup, with a pre-configured profile (e.g. clear redundant packages and browser cache). The website is lacking any documentation or usage instructions, and I could not find any information on this here as well. I tried, naturally, to start ubuntu-tweak from the command line, hoping additional API exists that will come through in this (allegedly) simple task. I only got as far as: ubuntu-tweak -f janitor which is a step in the right direction, but what's still missing is a command for the clear action. Is such a command available, or is there any better way of achieving the desired behavior?

  • google maps based desktop application

    - by dramaticlook
    I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!

  • The design of a generic data synchronizer, or, an [object] that does [actions] with the aid of [helpers]

    - by acheong87
    I'd like to create a generic data-source "synchronizer," where data-source "types" may include MySQL databases, Google Spreadsheets documents, CSV files, among others. I've been trying to figure out how to structure this in terms of classes and interfaces, keeping in mind (what I've read about) composition vs. inheritance and is-a vs. has-a, but each route I go down seems to violate some principle. For simplicity, assume that all data-sources have a header-row-plus-data-rows format. For example, assume that the first rows of Google Spreadsheets documents and CSV files will have column headers, a.k.a. "fields" (to parallel database fields). Also, eventually, I would like to implement this in PHP, but avoiding language-specific discussion would probably be more productive. Here's an overview of what I've tried. Part 1/4: ISyncable class CMySQL implements ISyncable GetFields() // sql query, pdo statement, whatever AddFields() RemFields() ... _dbh class CGoogleSpreadsheets implements ISyncable GetFields() // zend gdata api AddFields() RemFields() ... _spreadsheetKey _worksheetId class CCsvFile implements ISyncable GetFields() // read from buffer AddFields() RemFields() ... _buffer interface ISyncable GetFields() AddFields($field1, $field2, ...) RemFields($field1, $field2, ...) ... CanAddFields() // maybe the spreadsheet is locked for write, or CanRemFields() // maybe no permission to alter a database table ... AddRow() ModRow() RemRow() ... Open() Close() ... First Question: Does it make sense to use an interface, as above? Part 2/4: CSyncer Next, the thing that does the syncing. class CSyncer __construct(ISyncable $A, ISyncable $B) Push() // sync A to B Pull() // sync B to A Sync() // Push() and Pull() only differ in direction; factor. // Sync()'s job is to make sure that the fields on each side // match, to add fields where appropriate and possible, to // account for different column-orderings, etc., and of // course, to add and remove rows as necessary to sync. ... _A _B Second Question: Does it make sense to define such a class, or am I treading dangerously close to the "Kingdom of Nouns"? Part 3/4: CTranslator? ITranslator? Now, here's where I actually get lost, assuming the above is passable. Sometimes, two ISyncables speak different "dialects." For example, believe it or not, Google Spreadsheets (accessed through the Google Data API "list feed") returns column headers lower-cased and stripped of all spaces and symbols! That is, sys_TIMESTAMP is systimestamp, as far as my code can tell. (Yes, I am aware that the "cell feed" does not strip the name so; however cell-by-cell manipulation is too slow for what I'm doing.) One can imagine other hypothetical examples. Perhaps even the data itself can be in different "dialects." But let's take it as given for now, and not argue this if possible. Third Question: How would you implement "translation"? Note: Taking all this as an exercise, I'm more interested in the "idealized" design, rather than the practical one. (God knows that shipped sailed when I began this project.) Part 4/4: Further Thought Here's my train of thought to demonstrate I've thunk, albeit unfruitfully: First, I thought, primitively, "I'll just modify CMySQL::GetFields() to lower-case and strip field names so they're compatible with Google Spreadsheets." But of course, then my class should really be called, CMySQLForGoogleSpreadsheets, and that can't be right. So, the thing which translates must exist outside of an ISyncable implementor. And surely it can't be right to make each translation a method in CSyncer. If it exists outside of both ISyncable and CSyncer, then what is it? (Is it even an "it"?) Is it an abstract class, i.e. abstract CTranslator? Is it an interface, since a translator only does, not has, i.e. interface ITranslator? Does it even require instantiation? e.g. If it's an ITranslator, then should its translation methods be static? (I learned what "late static binding" meant, today.) And, dear God, whatever it is, how should a CSyncer use it? Does it "have" it? Is it, "it"? Who am I? ...am I, "I"? I've attempted to break up the question into sub-questions, but essentially my question is singular: How does one implement an object A that conceptually "links" (has) two objects b1 and b2 that share a common interface B, where certain pairs of b1 and b2 require a helper, e.g. a translator, to be handled by A? Something tells me that I've overcomplicated this design, or violated a principle much higher up. Thank you all very much for your time and any advice you can provide.

  • Which CMS can I use for my project?

    - by Nicolás A.
    I have to build a new website for my client.. and he needs this stuff: A user generated content website.. where users can upload their own videos.. (i will use a video hosting platform with api like fliqz.com) I must manage a big user system.. where users can create their own "sub-users"... the site must manage paid subscriptions and payments through paypal.. and other payment gateways... So the question is.. i have to use a pre-built CMS and extend it.. or just a good framework? I've been thinking about joomla, drupal and expressionengine... It's not neccesary to use a open source cms... I've looking at drupal.. but is not as easy to understand and extend... Can anyone help me to make a good decision?

  • SmS Gateways - How do other sites do it? [closed]

    - by chobo2
    Possible Duplicate: Send and Receive SMS from my Website I would love to have a feature on my site that sends Email reminders and SmS(text messages) to people mobile phones. I been searching around and all I am finding is api's that charge money per SmS message(as low as 1cent per message). However even at 1cent per message that is still too much. The amount of money I am charging per year could be servilely eroded by just the Sms messages along. I could of course charge more money for my service or have an add on for SmS messages but I don't think either would work as most people expect it to be free feature and if they have to pay anything that is because of their carrier charging them not the website. How do other sites do it? I guessing companies like google have their own gateway providers or something like that. But how about smaller sites what do they do? I can't see them paying per sms text message.

  • Should an object know its own ID?

    - by xenoterracide
    obj.id seems fairly common and also seems to fall within the range of something an object could know about itself. I find myself asking why should my object know its own id? It doesn't seem to have a reason to have it? One of the main reason for it existing is retrieve it, and so my repositories need to know it, and thus use it for database interaction. I also once encountered a problem where I wanted to serialize an object to JSON for a RESTful API where the id did not seem to fit in the payload, but only the URI and including it in the object made that more difficult. Should an object know it's own id? why or why not?

  • How to access / query Team Foundation Server 2012 with Odata?

    - by cseder
    I've tried to find a solution for this for hours now, and I'm getting the same results in the end, asking me to install a lot of Azure and other stuff, plus running some example project .sln that I can't open with my 2012 version of Visual Studio. So, I'm pretty much stuck, and have some pretty straight forward questions regarding this: Does TFS 2012 include the Odata service in any way, so that I don't have to install it? If not, how can I install a NATIVE 2012 version of the Odata service for TFS 2012? Is it possible that I'm aiming for the wrong target here? I'm looking for a solution to the following: I have a TFS 2012 Server that I need to be able to create Work Items on programatically, based on data from our Help Desk system. Then I need to query these Work Items for changed status since its creation, and update the Help Desk Database. Am I better off using the "regular" TFS API? I was kinda thinking that the Odata way was more "future proof", but I'm not sure...

  • Is avoiding the private access specifier in PHP justified?

    - by Tifa
    I come from a Java background and I have been working with PHP for almost a year now. I have worked with WordPress, Zend and currently I'm using CakePHP. I was going through Cake's lib and I couldn't help notice that Cake goes a long way avoiding the "private" access specifier. Cake says Try to avoid private methods or variables, though, in favor of protected ones. The latter can be accessed or modified by subclasses, whereas private ones prevent extension or re-use. in this tutorial. Why does Cake overly shun the "private" access specifier while good OO design encourages its use i.e to apply the most restrictive visibility for a class member that is not intended to be part of its exported API? I'm willing to believe that "private" functions are difficult test, but is rest of the convention justified outside Cake? or perhaps it's just a Cake convention of OO design geared towards extensibility at the expense of being a stickler for stringent (or traditional?) OO design?

  • TDD, new tests while old ones not implemented yet

    - by liori
    I am experimenting with test-driven development, and I found that I often come to a following situation: I write tests for some functionality X. Those tests fail. While trying to implement X, I see that I need to implement some feature Y in a lower layer of my code. So... I write tests for Y. Now both tests for X and Y fail. Once I had 4 features in different layers of code being worked on at the same time, and I was losing my focus on what I am actually doing (too many tests failing at the same time). I think I could solve this by putting more effort into planning my tasks even before I start writing tests. But in some cases I didn't know that I will need to go deeper, because e.g. I didn't know the API of lower layer very well. What should I do in such cases? Does TDD have any recommendations?

  • Google App Engine: How to be notified when APIs change or become available?

    - by herpylderp
    I am thinking about writing a GAE app but am a little hesitant because the EULA gives Google full rights to change their APIs anytime they want, for any reason. Obviously, they'd be out of business quick if they just 'upped and refactored their entire APIs, so I have to imagine they have some kind of notification system, perhaps even an RSS feed, etc. to notify developers well in advance of looming changes, or new features coming out in future releases. However, for the life of me I can't seem to find any trace of the existence of such a notification system. Perhaps the Google forums is the only place to get such updates? I guess I'm asking any battle-worn GAE veterans for re-assurance that there are reliable ways of getting notifications about policy or API changes from Google such that I could react and make the necessary app changes without production breaking or impacting any clients. Thanks in advance!

  • Architecture for dashbaord showing aggregated stats

    - by soulnafein
    I'm trying to find the best architecture for an application that shows a dashboard with aggregated stats that come from another one (e.g. number of sales in the last 12 months, current sales this month, a fairly complex score, performance of users over last 30 days, etc.) There is a fair bit of business logic that lives in Application 1 but the aggregated data gets saved in Application 2 (dashboard). What's the best way to create the aggregate data? 1) Pull data directly from Application 1 database and duplicate business logic for score calculation etc. 2) Push data from Application 1 to Application 2 somehow 3) Aggregate data in Application 1 on the fly and provide and api for Application 2 4) Other (probably) Please suggest solutions, Thanks.

  • Data Source Security Part 1

    - by Steve Felts
    I’ve written a couple of articles on how to store data source security credentials using the Oracle wallet.  I plan to write a few articles on the various types of security available to WebLogic Server (WLS) data sources.  There are more options than you might think! There have been several enhancements in this area in WLS 10.3.6.  There are a couple of more enhancements planned for release WLS 12.1.2 that I will include here for completeness.  This isn’t intended as a teaser.  If you call your Oracle support person, you can get them now as minor patches to WLS 10.3.6.   The current security documentation is scattered in a few places, has a few incorrect statements, and is missing a few topics.  It also seems that the knowledge of how to apply some of these features isn’t written down.  The goal of these articles is to talk about WLS data source security in a unified way and to introduce some approaches to using the available features.  Introduction to WebLogic Data Source Security Options By default, you define a single database user and password for a data source.  You can store it in the data source descriptor or make use of the Oracle wallet.  This is a very simple and efficient approach to security.  All of the connections in the connection pool are owned by this user and there is no special processing when a connection is given out.  That is, it’s a homogeneous connection pool and any request can get any connection from a security perspective (there are other aspects like affinity).  Regardless of the end user of the application, all connections in the pool use the same security credentials to access the DBMS.   No additional information is needed when you get a connection because it’s all available from the data source descriptor (or wallet). java.sql.Connection conn =  mydatasource.getConnection(); Note: You can enter the password as a name-value pair in the Properties field (this not permitted for production environments) or you can enter it in the Password field of the data source descriptor. The value in the Password field overrides any password value defined in the Properties passed to the JDBC Driver when creating physical database connections. It is recommended that you use the Password attribute in place of the password property in the properties string because the Password value is encrypted in the configuration file (stored as the password-encrypted attribute in the jdbc-driver-params tag in the module file) and is hidden in the administration console.  The Properties and Password fields are located on the administration console Data Source creation wizard or Data Source Configuration tab. The JDBC API can also be used to programmatically specify a database user name and password as in the following.  java.sql.Connection conn = mydatasource.getConnection(“user”, “password”); According to the JDBC specification, it’s supposed to take a database user and associated password but different vendors implement this differently.  WLS, by default, treats this as an application server user and password.  The pair is authenticated to see if it’s a valid user and that user is used for WLS security permission checks.  By default, the user is then mapped to a database user and password using the data source credential mapper, so this API sort of follows the specification but database credentials are one-step removed from the application code.  More details and the rationale are described later. While the default approach is simple, it does mean that only one database user is doing all of the work.  You can’t figure out who actually did the update and you can’t restrict SQL operations by who is running the operation, at least at the database level.   Any type of per-user logic will need to be in the application code instead of having the database do it.  There are various WLS data source features that can be configured to provide some per-user information about the operations to the database. WebLogic Data Source Security Options This table describes the features available for WebLogic data sources to configure database security credentials and a brief description.  It also captures information about the compatibility of these features with one another. Feature Description Can be used with Can’t be used with User authentication (default) Default getConnection(user, password) behavior – validate the input and use the user/password in the descriptor. Set client identifier Proxy Session, Identity pooling, Use database credentials Use database credentials Instead of using the credential mapper, use the supplied user and password directly. Set client identifier, Proxy session, Identity pooling User authentication, Multi Data Source Set Client Identifier Set a client identifier property associated with the connection (Oracle and DB2 only). Everything Proxy Session Set a light-weight proxy user associated with the connection (Oracle-only). Set client identifier, Use database credentials Identity pooling, User authentication Identity pooling Heterogeneous pool of connections owned by specified users. Set client identifier, Use database credentials Proxy session, User authentication, Labeling, Multi-datasource, Active GridLink Note that all of these features are available with both XA and non-XA drivers. Currently, the Proxy Session and Use Database Credentials options are on the Oracle tab of the Data Source Configuration tab of the administration console (even though the Use Database Credentials feature is not just for Oracle databases – oops).  The rest of the features are on the Identity tab of the Data Source Configuration tab in the administration console (plan on seeing them all in one place in the future). The subsequent articles will describe these features in more detail.  Keep referring back to this table to see the big picture.

  • Upgrading an app to support iOS5, 6 and 7

    - by drekka
    We are looking at an app that needs an upgrade. Currently it runs on iOS4, 5 & 6. The upgrade will move to iOS5, 6 & 7. It will also involve some UI changes and new features. I've been reading stuff on iOS7 and looking at things like auto-layout. What we are trying to figure out is the best way to handle the differences between the various iOS versions. Auto-layout seems like a good idea, but it's not available on iOS 5. There are also API changes to consider between all 3 versions and other new features of iOS7. So the questions: How would you handle auto layout given iOS5 does not have it? Are there any significant differences between the SDKs that you think would cause issues? Would we be better off with separate code bases?

  • I am new to game development, what do I need to know? [closed]

    - by farmdve
    I am unsure if this question is a duplicate, I hope it isn't. Are there any resources on the terminology when doing game development? Because, even if you tell me to learn some graphics API, how would I understand the things it does, if I am not well into the terminology(voxel,mesh,polygon,shading). What about the math that is involved in the game(geometry) or the concept of the gravity,collision detection in the game and their respective maths? I am very bad at math, never was good, because I have ADHD, but I won't give up just yet. I look at a game, and I see "textures", but how am I walking on them, how do they take substance so I don't fall off of them? And depth? This is what I need information about, not just a link to a library like SDL(which I have compiled under MinGW and MinGW-W64) and tell me to learn it and the cliché answer "start simple/small". I hope the question(s) are not too vague.
