• Best way to convert between [Char] and [Word8]?

  - by cmars232

  I'm new to Haskell and I'm trying to use a pure SHA1 implementation in my app (Data.Digest.Pure.SHA) with a JSON library (AttoJSON). AttoJSON uses Data.ByteString.Char8 bytestrings, SHA uses Data.ByteString.Lazy bytestrings, and some of my string literals in my app are [Char]. This article seems to indicate this is something still being worked out in the Haskell language/Prelude: http // hackage.haskell.org/trac/haskell-prime/wiki/CharAsUnicode And this one lists a few libraries but its a couple years old: http //blog.kfish.org/2007/10/survey-haskell-unicode-support.html [Links broken because SO doesn't trust me -- whatever...] What is the current best way to convert between these types, and what are some of the tradeoffs? I don't want to pick something that is obsolete... Thanks!

• What is the best way to handle dynamic content_type in Sinatra

  - by lusis

  I'm currently doing the following but it feels "kludgy": module Sinatra module DynFormat def dform(data,ct) if ct == 'xml';return data.to_xml;end if ct == 'json';return data.to_json;end end end helpers DynFormat end My goal is to plan ahead. Right now we're only working with XML for this particular web service but we want to move over to JSON as soon as all the components in our stack support it. Here's a sample route: get '/api/people/named/:name/:format' do format = params[:format] h = {'xml' => 'text/xml','json' => 'application/json'} content_type h[format], :charset => 'utf-8' person = params[:name] salesperson = Salespeople.find(:all, :conditions => ['name LIKE ?', "%#{person}%"]) "#{dform(salesperson,format)}" end It just feels like I'm not doing it the best way possible.

• What is the best way to read GetResponseStream() ?

  - by Dev Dona

  What is the best way to read an HTTP response from GetResponseStream ? Currently I'm using the following approach. Using SReader As StreamReader = New StreamReader(HttpRes.GetResponseStream) SourceCode = SReader.ReadToEnd() End Using I'm not quite sure if this is the most effecient way to read an http response. I need the output as string, I've seen an article ( http://www.informit.com/guides/content.aspx?g=dotnet&seqNum=583 ) with a different approach but I'm not quite if it's a good one. And in my tests that code had some encoding issues with in different websites. How do you read web responses?

• Best way to delay access to static web pages until services become available with J2EE

  - by Dean Povey

  I have a J2EE application front-ended by a bunch of GWT pages. When the server is starting up, it is possible that these static pages can be accessed before the services required to implement the GWT RPC calls (database etc) are available. I wondering what the best approach is to prevent a user accessing this static content before these services become available. For the purpose of this exercise, assume that there is an isInitialized() method somewhere. I am happy with either a page displaying an error message or simply refusing the connection.

• Best way to notify several java applets/applications of a change on a server

  - by Dustin

  I need to know the best (fastest) way to have a server (preferably a php based one, but a jsp/servlet one could be set up as well using google app engine) notify several java applets/applications that a change has occurred to the data. The way i am picturing this to work will be very similar to that of the way i think an online java game (like Runescape) works User 1: Changes data on server. Server: returns success to User 1, notifies connected computers of change. Connected Computer 1: processes change, returns success to server. Connected Computer 2: processes change, returns success to server. Connected Computer 3: processes change, returns success to server. Connected Computer 4: processes change, returns success to server. I am hoping to have this entire process complete in half a second, and not involve polling as there will be long durations of nothing, followed by a sudden moment where 4 events happen in succession.

• Input Sanitation Best Practices

  - by Adam Driscoll

  Our team has recently been working on a logic and data layer for our database. We were not approved to utilize Entity or Linq to SQL for the data layer. It was primarily built by hand. A lot of the SQL is auto generated. An obvious down fall of this is the need to sanitize inputs prior to retrieval and insertion. What are the best methods for doing this? Searching for terms like insert, delete, etc seems like a poor way to accomplish this. Is there a better alternative?

• Best approach to synchronising properties across threads

  - by user290796

  Hi, I'm looking for some advice on the best approach to synchronising access to properties of an object in C++. The application has an internal cache of objects which have 10 properties. These objects are to be requested in sets which can then have their properties modified and be re-saved. They can be accessed by 2-4 threads at any given time but access is not intense so my options are: Lock the property accessors for each object using a critical section. This means lots of critical sections - one for each object. Return copies of the objects when requested and have an update function which locks a single critical section to update the object properties when appropriate. I think option 2 seems the most efficient but I just want to see if I'm missing a hidden 3rd option which would be more appropriate. Thanks, J

• What is the best way to log a user in programatically in ExpressionEngine

  - by bjohnb

  I'm building an app that allows the app to hit an ACT url which then triggers a module method to create a new entry using the ExpressionEngine API. However, as there is no user logged in / loggin in, it is not allowed to submit an entry to a channel. What is the best way to do this. Bypass the EE api and submit the entry manually, or log a user in progamatically..but then how would that work with sessions etc etc? If the answer is to "log a user in" it would be great to see a code sample if possible. Thanks!

• Best way to get a date in .NET?

  - by frenchie

  I'm getting a string back from my page and I want to make sure it's a date. This is what I have so far (it works) and I just want to know if this is the "best" way to do it. I'm using .NET 4. int TheMonth =0; int TheDay = 0; int TheYear = 0; DateTime NewDate; var TheIncomingParam = Request.Params.Get("__EVENTARGUMENT").ToString(); char[] TheBreak = { '/' }; string[] TheOutput = TheIncomingParam.Split(TheBreak); try { TheMonth = Convert.ToInt32(TheOutput[0]); } catch { } try { TheDay = Convert.ToInt32(TheOutput[1]); } catch { } try { TheYear = Convert.ToInt32(TheOutput[2]); } catch { } if (TheMonth!=0 && TheDay!=0 && TheYear!=0) { try { NewDate = new DateTime(TheYear, TheMonth, TheDay); } catch { var NoDate = true; } }

• WCF Client - Best Practise

  - by user1663907

  I just wanted to hear your Opinion about a WCF Client implementation. I have an Server that provides several services like SecurityManager. This service is defined in the Interface ISecurityManager and implemented in the Class SecurityManager. So far everything is fine. On the Client side I want to implement the services calls via a seperated Class. My question is whether I do this also in an SecurityManager Class which implements the same ISecurityManager Interface? What is here the best practise? Thanks.

• Sql Server as logging, best connection practise

  - by ozz

  I'm using SqlServer as logging. Yes this is wrong decision, there are better dbs for this requirement. But I have no other option for now. Logging interval is 3 logs per second. So I've static Logger class and it has static Log method. Using "Open Connection" as static member is better for performance. But what is the best implemantation of it? This is not that I know. public static class OzzLogger { static SqlConnection Con; static OzzLogger() { Con=ne SqlConnection(....); Con.Open(); } public static void Log(....) { Con.ExecuteSql(......); } } UPDATE I asked because of my old information. People say "connection pooling performance is enough". If there is no objection I'm closing the issue :)

• Best way to test class methods without running __init__

  - by KenFar

  I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little.

• Best way to utilise an include file which just includes an array in PHP

  - by alex

  Kohana's config files look like this.. here is an example of a database config file (simplified) return array( 'dbhost' => 'localhost', 'user' => 'Tom_Jones' ); I've also got a CMS which wants the connection details. Whilst the CMS uses a different user (with more rights), I'd like to know the best way to include this file and get the data out of it (so as to not repeat myself for hostname and dbname). I haven't thought up of any elegant solutions yet and have not yet dug around Kohana to see how it does it. It's late Friday here so it's probably really obvious to everyone except me. UPDATE My apologies, I forgot to include that this is using Kohana 3!

• Best way to create a Unique ID field for an enum

  - by jax

  What is the best way to get a Unique ID from an ENUM that will stay consistent between repeated execution of the program? Currently I am doing this manually by passing an ID to the enum constructor. I don't really want to do this is I can help it. Another option would be to use a static field that gets incremented for each enum value. The problem is that if later I decide to move the enum fields around or delete some this will cause problems with my program as the ID will be saved into user preferences. The ID can be any basic type or a String.

• Best way to access nested data structures?

  - by Blackshark

  I would like to know what the best way (performance wise) to access a large data structure is. There are about hundred ways to do it but what is the most accessible for the compiler to optimize? One can access a value by foo[someindex].bar[indexlist[i].subelement[j]].baz[0] or create some pointer aliases like sometype_t* tmpfoo = &foo[someindex]; tmpfoo->bar[indexlist[i].subelement[j]].baz[0] or create reference aliases like sometype_t &tmpfoo = foo[someindex]; tmpfoo.bar[indexlist[i].subelement[j]].baz[0] and so forth...

• Best way of obfuscating / encrypting form data on the iPhone

  - by cannyboy

  I want to create an app which holds sensitive information (imagine it's bank account details, thought it's not). The user enters this information on a form the first time the app starts up. I want this info to be saved, and available, any time the user uses the app (without having to enter a password). However, if the iPhone has a password lock on it, and is stolen, I don't want the data to be easily accessible from the file system. What is the best way of encrypting or obfuscating the data? There is not a lot of data, just a dozen NSStrings from the UITextFields on the form. I'm aware there are encryption export restrictions on the iPhone for non-US developers (I am in UK), so I would prefer to avoid going jumping through any of Apple's app submission hoops to get it on the store.

• What is the best back button jQuery plugin?

  - by Guichard

  I have found two plugins that enable the browser's back button to work across ajax interactions, but I can't determine which is better and why. The two plugins are history_remote and the history. The history plug in is simpler and seems to provide all the functionality I need, but I'm not sure I understand enough about them to make an intelligent decision. For my application, I need the plugin to allow the back button to work through ajax interactions, and I need to be able to bookmark the page at any point through the interactions. Which plug in is best in this scenario and why? Are there any other plug ins that I missed that might be better? Are there any limitations to these plugins that I'm missing (do they not work in certain situations etc)? Any information would be greatly appreciated.

• How to Best Setup a Website Project in VS.NET

  - by Jason

  I have very little experience with setting up a website from scratch in a .NET environment. As I am doing this now, I am wondering - what's the best way to go? Is it better to create a new Website Project, and include the various backend services and database code as part of that project, or is it better to split out the various aspects of the project? If the second, how would I go about doing that? I want to ensure that this project is easy to manage in the future (in terms of source control, deployment, etc), so I want to make sure I'm starting off on the right foot. I was unable to find any tutorials online, but if you have any, I would appreciate those as well. Thanks!

• Best place to create windows form objects

  - by user333484

  I'm creating a windows app in c# 2008 that will have around 8-10 dialog boxes. I want these forms to exist throughout the life of the program. Where's the best place to create and store the objects? I'm coming from Delphi, where Form objects were usually stored in global variables. I'm tempted to do it in the static Program class. Should I put them in the main form instead? Thanks for helping a C# newb out.

• Best solution to import records from MySQL database to MS SQL (Hourly)

  - by xkingpin

  I need to import records stored in a MySQL Database that I do not maintain into my Sql Server 2005 database (x64) We should import the records at an interval basis (probably 1 hour). What would be the best solution to perform the regular import? Windows Service (using reference MySql.data dll) Windows Client (could make it automated) SQL Extended Stored Procedure (is it possible to reference the MySQL.data dll?) SSIS package - Install MySQL ODBC driver The problem with #4 is that I do not really want to support the ODBC driver on the sql server. I'm not sure if you can even reference the x86 MySql.data dll into a x64 sql server process for #3. (Or if you can even reference that dll within a sql server project)

• Best way to handle storing (possibly NULL) char * in a std::string

  - by John

  class MyClass { public: void setVar(const char *str); private: std::string mStr; int maxLength; //we only store string up to this length }; What's the best approach to implement setVar when the external code is quite likely to pass in NULL for an empty string (and cannot be changed)? I currently do something a bit like: void MyClass::setVar(const char *str) { mStr.assign(str ? str : "",maxLength); } But it seems kind of messy. ideas?

• Best use of Jquery sliders and PHP

  - by Coronier

  Hello there, I have two questions: What's the best way to send sliders' values to a PHP page ? I'm associating each slider (several per page) with an hidden form so far, but I wonder if there's a "cleaner" way to do this. Related to the 1st question; I've some trouble with the script: var score = $(this).slider( "option", "value" ); $(this).closest("input[type=='hidden']").val(score); It doesn't set the value of the hidden input. Can somebody tells me what's wrong ? Thanks

• The best way to store username and password without a database

  - by Mokuchan

  Hello everyone, I want to build a simple single user login "library" in PHP, but I'm facing the following dilemma: how should I store username and password if I'm not using a database? A simple plain text file could be easily read and then the password could be easily decripted so that's not an option. If I create a php file with just <?php $Username= "username"; $Password= "password"; ?> then no one should be able to read it and I could simply include this file where I need it, but I'm not really sure you can't find a better way to do this! So what's, in your opinion, the best solution to this problem (and why)? Thanks

• Best way to handle different panels occupying same area

  - by gmnnn

  I have this application: I want to change the marked area when the user is clicked one of the navBarItems (like Microsoft OUTLOOK). I've been doing some research and a lot of people said that I can add several panels and show/hide them when user is clicked a navBarItem. But the area will contain a lot of gridviews and a lot of other controls. I don't know if I want to initialize all of them when application starts because it's gonna be hard on the cpu and memory to keep all the controls running at the same time. And I don't think it's an elegant solution for this kind of situation. But if I choose to initialize controls when user is clicked to corresponding navBarItem, it's gonna be laggy for the user. What is the best design approach for this situation? PS: I can use commercial libraries too. Thank you.
