  • what is the best way to have a Generic Comparer

    - by oo
    I have a lot of comparer classes where the class being compared is simply checking the name property of the object and doing a string compare. For example: public class ExerciseSorter : IComparer<Exercise> { public int Compare(Exercise x, Exercise y) { return String.Compare(x.Name, y.Name); } } public class CarSorter : IComparer<Car> { public int Compare(Car x, Car y) { return String.Compare(x.Name, y.Name); } } what is the best way to have this code generic so i dont need to write redundant code over and over again.

  • What's the best software analogy you've heard?

    - by Mantorok
    Hi Quite frequently I have to explain things to Project Managers who sometimes want to know a little bit more about something, and sometimes I try and come up with some analogy that best explains it. Now, I can't really kick this off with a good analagy because mine usually suck, but I would be interested in yours, or some you've heard that have been used to simplify explanations. One analogy that does come up often is when explaining Interfaces (i.e. .Net) to which I usually explain in terms of a vehicle has a driver interface, and all vehicles must implement that interface so that anyone who can drive a vehicle will be able to utilise it. Any more? Would like to hear some, both serious and humourous. Please close if a duplicate.

  • Want to know about the best framework available for my app

    - by vamyip
    Hello, I am trying to design a new application which basically aims at providing biometric authentication services. What I want to do is that the app will present the user with an interface where the user can get his eye scanned for authentication. The most important feature I want to incorporate is that the user need not have a webcam, the app must be able to read the eye from the display device i.e. CRT or LCD screen itself. I want info about the best framework available for this. Once successfully tested, I am planning to provide it as a webservice. Any one who will help me will get a royalty from my income.

  • Best OpenID library for Java

    - by Adam Crume
    I want users to be able to log into my website with OpenID, but I don't know which library to use. I know which ones are out there, but I would like to know which one would be best. I'm running JOnAS, but no web framework (no Spring, Struts, GWT, etc.). (Please don't chastise me for not using a web framework. I have my reasons.) For what it's worth, my web site is broken into multiple WARs, and I would prefer something that works well in that situation, but that's not a big deal. Does anyone have experience with the different libraries? Any experiences or wisdom you can share?

  • Best way to store weekly event in MySQL?

    - by mazin k.
    I have a table of weekly events that run on certain days of the week (e.g. MTWTh, MWF, etc.) and run on a certain time (e.g. 8am-5pm). What's the best way to store day of week information in MySQL to make retrieving and working with the data easiest? My CakePHP app is going to need to retrieve all events happening NOW(). For time of day, I would just use TIME. For days of the week, I had considered a 7-bit bitfield, a varchar ("MTWThFr" type deal) for the days of the week, but both of those seem like clunky solutions (the varchar being clunkier). Any suggestions?

  • Best ASP.NET Background Service Implementation

    - by Jason N. Gaylord
    What's the best implementation for more than one background service in an ASP.NET application? Timer Callback Timer timer = new Timer(new TimerCallback(MyWorkCallback), HttpContext, 5000, 5000); Thread or ThreadPool Thread thread = new Thread(Work); thread.IsBackground = true; thread.Start(); BackgroundWorker BackgroundWorker worker = new BackgroundWorker(); worker.DoWork += new DoWorkEventHandler(DoMyWork); worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(DoMyWork_Completed); worker.RunWorkerAsync(); Caching like http://www.codeproject.com/KB/aspnet/ASPNETService.aspx (located in Jeff Atwood's post here) I need to run multiple background "services" at a given time. One service may run every 5 minutes where another may be once a day. It will never be more than 10 services running at a time.

  • Best way to daemonize Java application on Linux

    - by SyBer
    Hi. While I found this question being answered here on SW several times, I didn't find a concluding answer what is the best approach. I'm not looking to use any external wrapper, as I found them launching the java process under a nice level lower then themselves which potentially lowers the performance, so it seems only the shell methods are left. I so far found 3 different shell methods: start-stop-daemon RedHat daemon init.d function nohup on start / disown after start What you people are using, and can recommend as the most reliable method? Thanks.

  • Best way to do syntax highlighting in GTK+?

    - by Tyler
    I was wondering if someone could point me to an example of (or just their thoughts on) the best way to code syntax highlighting in a C-based GTK+ application. I know that I can use the GtkTextTag to modify text in a GtkTextBuffer but beyond searching out keywords (iteratively or by regexing the string) is there a better way? My only concern is that if I wipe all of the tags and then re-search and apply the tags at every text change event it could really bog down my application. As always thanks for your help!

  • ASP.Net MVC - which is the best approach for multi select grouping using JQuery Dialog

    - by Rajeesh
    This is my scenario I have an view(page) with list of items, a user could select single or multiple items from this page and click on a "Add to Group" button. Then a modal dialog(JQuery dialog) will be shown, from that he could select group, then press the add button. Which causes the items selected in the parent page is added to that particular group. So, which is the best way to pass the selected items to the modal pop-up? Though the query string ? - what happens if the no:of items selected is large, will the url support that much characters Keep the list in the parent page in a javascript variable and return the selected group from the modal pop-up? Or is there is any other better option? Thanks, Rajeesh

  • The best alternative for String flyweight implementation in Java

    - by Dan
    My application is multithreaded with intensive String processing. We are experiencing excessive memory consumption and profiling has demonstrated that this is due to String data. I think that memory consumption would benefit greatly from using some kind of flyweight pattern implementation or even cache (I know for sure that Strings are often duplicated, although I don't have any hard data in that regard). I have looked at Java Constant Pool and String.intern, but it seems that it can provoke some PermGen problems. What would be the best alternative for implementing application-wide, multithreaded pool of Strings in java?

  • best content on how to deploy and share a VSTO solution

    - by ooo
    with the push to leverage visual studio and dotnet with office based solutions, especially excel, where is the best article or information on how having office sheet with additional binaries and assemblies is sharable. Do this external code get packaged with the spreadsheet what if people start emailing the spreadsheet around. Is there any overhead of this additional assemblies. Is there risk of the binaries getting detached from the spreadsheet It seems like microsoft has been pushing VSTO for over 5 years now but you read lots of mixed reviews and issues. Are we at the point where companies that do large VBA excel solutions can fully migrate over to dotnet without any real worries?

  • Best Practices for a Web App Staging Server (on a budget)

    - by fig-gnuton
    I'd like to set up a staging server for a Rails app. I use git & github, Cap, and have a VPS with Apache/Passenger. I'm curious as to the best practices for a staging setup, as far as both the configuration of the staging server as well as the processes for interacting with it. I do know it should be as identical to the production server as possible, but restricting public access to it will limit that, so tips on securing it only for my use would also be great. Another specific question would be whether I could just create a virtual host on the VPS, so that the staging server could reside alongside the production one. I have a feeling there may be reasons to avoid this, though.

  • Best way to store application images taken via camera

    - by Dave
    Hi all, I'm just looking for some insight into what would be the best way for me to store images as part of my app. I have an activity that represents a 'Job' which has a couple of edittext's and underneath was planning on using the Gallery component to show images relevant to this job. The job data is stored in a database (on the sdcard) so was also thinking of creating a table to store 'JobImages' and having each image stored as a byte array. But I'm not sure if it would be better to store the images directly on sdcard under a folder structure specific to my application and the job. E.g. using the job ID number as a folder name. Depending on which method I use will greatly determine the code that goes into an 'adapter' that allows me to bind to the gallery component so before I begin I was wondering if anyone has had the same design problem and what option they chose. Thanks, Dave

  • Best way to store chat messages and files

    - by Stnaire
    I would like to know what do you think about storing chat messages in a database? I need to be able to bind other stuff to them (like files, or contacts) and using a database is the best way I see for now. The same question comes for files, because they can be bound to chat messages, I have to store them in the database too.. With thousands of messages and files I wonder about performance drops and database size. What do you think considering I'm using PHP with MySQL/Doctrine?

  • Best way to get a reasonably random key for MYSQL records

    - by Steve N
    Hi there, I need to generate a reasonably random unique key for a table. It should be something like a GUID for MYSQL. I've tried UUID, but it looks like only the first few characters are actually random- the rest are the same every time I insert them. Essentially, it is desirable for this key field to be very difficult to guess, even if you already have one known value in the column. What is the best way to do this, and how should I set up the field data type to store the value efficiently? Thank you, Steve

  • Best Practices & Considerations when writing HTML Emails

    - by Jonathan Sampson
    I've been developing websites for over a decade now, but quickly found that many of my habits in developing for the web are useless when developing for email clients. This has caused me an enormous amount of frustration, so I thought I would ask a question that would hopefully surface the best practices and necessary considerations for others like myself who may find themselves designing for gmail, outlook, etc. from time to time. Example: <style>...</style> vs inline CSS. In short: what transfers over from the web-world to the email-world, and what doesn't.

  • Best way to test instance 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. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

  • best way to prgram php and mysql query

    - by air
    most of times in our pages we need to print only 1 field value of table in loop. for example <?php for($i=1;$i<=mysql_num_rows($result);$i++) { echo $row['name']; $sql1="select industry from table_industry where profid='".$row['prof']."'"; $result1=mysql_query($sql1); $row1=mysql_fetch_array($result1); echo $row1['industry']; ?> } ?> above is one PHP code just for example where we think that $row['prof'] carry value of profession ID and we print profession of each person. for example we have 5000+ record in table and above loop will execute for 5000+ times what will be the best way to print value of industry field from table table_industry Same code which i write above ? any other php code suggestion for faster execution and less use of resources? Thanks

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

  • Best way to implement nested loops in a view in asp.net mvc 2

    - by Junior Ewing
    Hi, Trying to implement some nested loops that are spitting out good old nested html table data. So the question is; What is the best way to loop through lists and nested lists in order to produce easily maintainable code. It can get quite narly quite fast when working with multiple nested tables or lists. Should I make use of a HTML helper, or make something with the ViewModel to simplify this? A requirement is if there are no children at a node there should be an empty row on that spot with some links for creation and into other parts of the system.

  • Best datastructure for this relationship...

    - by Travis
    I have a question about database 'style'. I need a method of storing user accounts. Some users "own" other user accounts (sub-accounts). However not all user accounts are owned, just some. Is it best to represent this using a table structure like so... TABLE accounts ( ID ownerID -> ID name ) ...even though there will be some NULL values in the ownerID column for accounts that do not have an owner. Or would it be stylistically preferable to have two tables, like so. TABLE accounts ( ID name ) TABLE ownedAccounts ( accountID -> accounts(ID) ownerID -> accounts(ID) ) Thanks for the advice.

  • Best method of Zend Framework caching

    - by iamthejeff
    I have a blog built using Zend Framework, which I realize might be a bit overkill for a blog alone, but I am planning on adding other features in the future. Nevertheless, I've noticed pages could be a little speedier. I've done a basic caching method that basically captures everything in index.php (Core frontend and File backend), which works great, but unfortunately it also prevents dynamic page contents from updating (messages like "this was posted 5 minutes ago", etc) until the cache period expires. So my question is what would be the best method of caching to improve performance? I am doing fairly basic queries which are mostly simple selects, not many joins or anything fancy (using Zend_Db_Table), and even on a small database page loads are a little sluggish. Is it worth it to cache queries or should I focus my time elsewhere?

  • Whats the best way to deal with backups for my php/mysql application

    - by spirytus
    I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

  • best way to build iphone settings screen

    - by Christian Schlensker
    I'm building a settings screen for an iPhone app and it is supposed to resemble a grouped table view. Each "cell" should behave like a button. Most cells just have a image view, label view, and disclosure indicator. One will display a value in addition to a label. All of these buttons will present a new view when tapped. Now, how to implement this? I was considering just laying out a set of buttons with custom background images, or would it be best to just use a table view. If that's the case what should it be implemented. So far I've only used table views to display some kind of dynamic data in which each cell displayed the same basic detail view. I'm most curious to figure out how to setup cellForRowAtIndexPath. Would this contain some sort of switch statement to configure each cell individually, or is there an easier way to handle all this?
