  • Best way to design a class in python

    - by Fraz
    So, this is more like a philosophical question for someone who is trying to understand classes. Most of time, how i use class is actually a very bad way to use it. I think of a lot of functions and after a time just indent the code and makes it a class and replacing few stuff with self.variable if a variable is repeated a lot. (I know its bad practise) But anyways... What i am asking is: class FooBar: def __init__(self,foo,bar): self._foo = foo self._bar = bar self.ans = self.__execute() def __execute(self): return something(self._foo, self._bar) Now there are many ways to do this: class FooBar: def __init__(self,foo): self._foo = foo def execute(self,bar): return something(self._foo, bar) Can you suggest which one is bad and which one is worse? or any other way to do this. This is just a toy example (offcourse). I mean, there is no need to have a class here if there is one function.. but lets say in __execute something() calls a whole set of other methods.. ?? Thanks

  • What is the best way to add two strings together?

    - by Pim Jager
    I read somewehere (I thought on codinghorror) that it is bad practice to add strings together as if they are numbers, since like numbers, strings cannot be changed. Thus, adding them together creates a new string. So, I was wondering, what is the best way to add two strings together, when focusing on performance? Which of these four is better, or is there another way which is better? //Note that normally at least one of these two strings is variable $str1 = 'Hello '; $str2 = 'World!'; $output1 = $str1.$str2; //This is said to be bad $str1 = 'Hello '; $output2 = $str1.'World!'; //Also bad $str1 = 'Hello'; $str2 = 'World!'; $output3 = sprintf('%s %s', $str1, $str2); //Good? //This last one is probaply more common as: //$output = sprintf('%s %s', 'Hello', 'World!'); $str1 = 'Hello '; $str2 = '{a}World!'; $output4 = str_replace('{a}', $str1, $str2); Does it even matter?

  • web development with ruby without rails?

    - by kmorris511
    For reasons beyond my control, I'm being tasked with Ruby web development that does NOT use Rails or really any other heavyweight framework such as Merb. I'm wondering if anybody else has encountered this and can recommend best practices or resources that describe best practices for such a problem. I'd like to avoid the dreaded out.print('<td class="foo">'+some_data+'</td>') style of web development. A coworker has suggested Rack as a light framework but the documentation is sketchy and it seems unproven in the market.

  • Testing sample code in python modules

    - by Andrew Walker
    I'm in the process of writing a python module that includes some samples. These samples aren't unit-tests, and they are too long and complex to be doctests. I'm interested in best practices for automatically checking that these samples run. My current project layout is pretty standard, except that there is an extra top level makefile that has build, install, unittest, coverage and profile targets, that delegate responsibility to setup.py and nose as required. projectname/ Makefile README setup.py samples/ foo-sample foobar-sample projectname/ __init__.py foo.py bar.py tests/ test-foo.py test-bar.py I've considered adding a sampletest module, or adding nose.tools.istest decorators to the entry-point functions of the samples, but for a small number of samples, these solutions sound a bit ugly. This question is similar to http://stackoverflow.com/questions/301365/automatically-unit-test-example-code, but I assume python best practices will differ from C#

  • i18n and l10n web guidelines

    - by Konstantin Petrukhnov
    Is there any standards/guidelines/good practices for making websites with support of different content and UI? I'm interesting in articles/tutorials, that cover this topics. E.g. there going to be website for multiple countries. And user should have possibility to select UI and content languages separately. I assume that not all content will be translated, so there should be some mechanism for showing "default language" content for specific page. But again, should this "default" be per site, or per country? E.g. in some countries (Belgium, Finland) there are several official languages. If one language is unavailable, should default be second one, or English? Another example: many people prefer English UI (no mater of their origin), but want local scales (inches, meters) and local services. I don't care much about programing languages now, just want to understand what users are expected, what should be scope, and what are good practices.

  • WSS 3.0 navigation structure

    - by Dante
    Hi all, I'm a beginner in WSS 3.0 and I'm having some problems with the navigation setup. I can't find any documentation that clearly recommends best practices in this area. I'm trying to create an intranet, custom look and feel, that should have a structure similar to: Company - News - News type 1 - News type 2 - Organogram - ... Employees - Employees 1 - Employees 2 - Employees 2_1 - ... How to properly set this up? Company, News, are sites/subsites? And News type 1 and 2 are pages within a site? I created as described above and in the master page of the main site I added some scripts that will be used by web parts, like jquery. The subsites will have their own master page and will not recognize the scripts, I need to add them there which is annoying. Any recommendations? Or some resource that provides best practices setting up these structures? Thx in advance

  • Java webapp: where/how to automatically set each picture's width/height

    - by NoozNooz42
    For several reasons, a lot of "webmaster guides" (like Google and Yahoo!'s webmaster guides/guidelines) repeats several times that it is better to always put the width and height attribute of the img tag. One of the most obvious reason is that the elements in the page won't seem to be "jumping around" to a new location after every picture is loaded (always setting the correct width/height sure gets rid of this behavior). And there are other reasons to follow these guidelines / best practices. So: if we consider that these are indeed good practices if there are a lot of pictures and they are changing often if pictures aren't changing between two .war re-deploy (that is: there's no user-contributed picture) if we don't want to manually edit all these width/height attributes How do we automatically/programmatically serve HTML pages where every img tag have their width/height attribute correctly set as the best practice recommend?

  • Coding Standards

    - by kevchadders
    For those of us that have programmed enough I’m sure we have come across many different flavours of coding standards that you can use when it comes to programming. e.g. http://msdn.microsoft.com/en-us/library/ms229042.aspx You might derive your coding standards for the current company you work for or from the original author of the code you’re working on. Coding styles are often used for specific program languages and some styles in one coding language might not be considered appropriate for others. Of course some coding standards can be applied across many different program languages. My question is do you have any good advice/links yourselves to a set of coding standards that you would recommend to others, or best practices to follow? Thank you for your time. EDIT: As we know there are many related articles on this subject, but C# Coding standard / Best practices in SO has some very useful links in there which is worth a visit. (Check out the 2 links on .NET/C# guidelines by ESV - Accepted Answer)

  • Aop, Unity, Interceptors and ASP.NET MVC Controller Action Methods

    - by Richard Ev
    Using log4net we would like to log all calls to our ASP.NET MVC controller action methods. The logs should include information about any parameters that were passed to the controller. Rather than hand-coding this in each action method we hope to use an AoP approach with Interceptors via Unity. We already have this working with some other classes that use interfaces (using the InterfaceInterceptor). However, we're not sure how to proceed with our controllers. Should we re-work them slightly to use an interface, or is there a simpler approach? Edit The VirtualMethodInterceptor seems to be the correct approach, however using this results in the following exception: System.ArgumentNullException: Value cannot be null. Parameter name: str at System.Reflection.Emit.DynamicILGenerator.Emit(OpCode opcode, String str) at Microsoft.Practices.ObjectBuilder2.DynamicMethodConstructorStrategy.PreBuildUp(IBuilderContext context) at Microsoft.Practices.ObjectBuilder2.StrategyChain.ExecuteBuildUp(IBuilderContext context)

  • MVVM View reference to ViewModel

    - by BrettRobi
    I'm using MVVM in a WPF app. I'm very new to both. Let me state that I am not a purest in the MVVM pattern, I am trying to use as many best practices as I can but am trying to make what I think are reasonable compromises to make it work in our environment. For example, I am not trying to achieve 0% code in my View codebehind. I have a couple of questions about best practices. 1) I understand I don't want my VM to know about the attached View, but is it reasonable for the View to have a reference to its VM? 2) If a control in a View opens another View (such as a dialog) should I handle this in the View? It seems wrong to handle it in the VM since then the VM has some knowledge of a specific View.

  • Can expiration policies be configured in entlib caching application block?

    - by stesoc
    Hi, Is there a way to tell a CacheManager that every item added will have the same expiration policy? For example in: <cachingConfiguration defaultCacheManager="DefaultCacheManager"> <cacheManagers> <add name="TestCM" expirationPollFrequencyInSeconds="60" maximumElementsInCacheBeforeScavenging="1000" numberToRemoveWhenScavenging="10" backingStoreName="Null Storage" type="Microsoft.Practices.EnterpriseLibrary.Caching.CacheManager, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> I expected to have some attribute like expirationPolicy="AbsoluteTime" or "SlidingTime" and a expirationValue="..." for specifying the timespan to use. Thanks, s.

  • When to use Vanilla Javascript vs. jQuery?

    - by jondavidjohn
    I have noticed while monitoring/attempting to answer common jQuery questions, that there are certain practices using javascript, instead of jQuery, that actually enable you to write less and do ... well the same amount. And may also yield performance benefits. A specific example $(this) vs this Inside a click event referencing the clicked objects id jQuery $(this).attr("id"); Javascript this.id; Are there any other common practices like this? Where certain Javascript operations could be accomplished easier, without bringing jQuery into the mix. Or is this a rare case? (of a jQuery "shortcut" actually requiring more code) EDIT : While I appreciate the answers regarding jQuery vs. plain javascript performance, I am actually looking for much more quantitative answers. While using jQuery, instances where one would actually be better off (readability/compactness) to use plain javascript instead of using $(). In addition to the example I gave in my original question.

  • Multiple Asserts in a Unit Test

    - by whatispunk
    I've just finished reading Roy Osherove's "The Art of Unit Testing" and I am trying to adhere to the best practices he lays out in the book. One of those best practices is to not use multiple asserts in a test method. The reason for this rule is fairly clear to me, but it makes me wonder... If I have a method like: public Foo MakeFoo(int x, int y, int z) { Foo f = new Foo(); f.X = x; f.Y = y; f.Z = z; return f; } Must I really write individual unit tests to assert each separate property of Foo is initialized with the supplied value? Is it really all that uncommon to use multiple asserts in a test method? FYI: I am using MSTest.

  • Where can I find a deliberately insecure open source web application?

    - by Phil Laliberte
    As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

  • Best language to develop medical software

    - by Grace
    I need to write medical program to manage medical practices (patient records, appointments, prescription, etc). Note that this is not for US practices so US EMRs will not work. What is the best platform to develop the software in ie. language and database? Considerations include: - Integration with the web - will need to have Doctors download updates to the software from the web. Will also post reports from the software unto webpages - The software will include a mobile application - probably for Blackberry - Cost is a big factor - need to minimize the license cost to the users - Need tight security on the program

  • sample/good rails projects to learn from

    - by learningrails
    I am just starting with Rails. I've read through the AWDR book and am currently working on a side project in rails. I want to get an idea of what a good rails project should look like in order to learn what the best practices are. Can you guys point me to some good rails projects on github that not only work well but are well written? Or am I better off reading Rails best practices? if so, any good ones?

  • Asp.net Report Viewer - Custom filter parameters

    - by Chris
    Hi all, for a data warehouse project I need to know about some best practices regarding custom report viewer filters/parameters. Usually I use the standard parameter feature for reports, like multiple select boxes, check boxes, text boxes etc.. But for the current project some reports require more complex report parameters. E.g. a user wants to analyze some measures. For that the user needs to set a filter on a specific address. There are over 100.000 address to choose from, so he has to have the ability to search for an address (full text). Since such features cannot be done with the standard parameters, I will have to create custom params within a ASPX page which are then passed to the report viewer control. So my question is: Are there any best practices on how to create custom parameters? Did anyone had similar problems, if so, how did you solve it?

  • Conditional Statements - If Then vs. Select Case

    - by cloyd800
    I'm a bit new to programming, and based on the few sources I've read both on the web and the books I'm learning to teach myself they are able to define what IF THEN and SELECT CASE conditional statements are, but have failed to give a comparison as to why I would use one over the other and what best practices decide this. If I'm understanding these conditional statements correctly, then both are based on a set of conditions with an outcome based around meeting these conditions, and if no conditions are met then an alternative outcome can be defined. I'm having trouble in understanding when I would use an IF THEN statement, and when I'd use a SELECT CASE statement, and what best practices are used to define this decision. Any insight on this would be greatly appreciated!
