• When to use buildout:eggs and when to install via zc.recipe.egg ?

  - by chiggsy

  There seem to be more than one way to install eggs into a buildout. Way 1: [buildout] ... eggs = eggname othereggname ... Way 2: [buildout] ... parts = eggs [eggs] recipe = zc.recipe.egg eggs = eggname = othereggname Both ways work. ( variation on way 2 would be to install each requirement as a separate part. ) What is the difference between these 2 methods? For my projects, I'm using buildout with djangorecipe and mr.developer.

• What are the requirements for an application health monitoring system?

  - by Steven A. Lowe

  What, at a minimum, should an application health-monitoring system do for you (the developer) and/or your boss (the IT Manager) and/or the oeprations (on-call) staff? What else should it do above the minimum requirements? Is monitoring the 'infrastructure' applications (ms-exchange, apache, etc.) sufficient or do individual user applications, web sites, and databases also need to be monitored? if the latter, what do you need to know about them? ADDENDUM: thanks for the input, i was really looking for application-level monitoring not infrastructure monitoring, but it is good to know about both

• How do you use scripting language (PHP, Python, etc) to improve your productivity?

  - by Edwin

  Hi, I'm a Delphi developer on the Windows platform, recently read the PHP tutorial at W3CSchools, it looks interesting. We all know scripting languages are very good at web site development, but I also want to utilize it to improve my productivity or get some tedious tasks done quickly, maybe some quick-and-dirty string/file processing? How do you usually do with scripting languages apart from software development? And we need a responsive, decent IDE/editor in order to gain productivity when writing scripts for this purpose? Thanks for in advance!

• Current state of client-side XSLT

  - by Casey

  Last I heard, Blizzard was one of the few companies to put client-side XSLT into practice (2008). Is this still the case in 2011, or are more people now exploring this technique in production?  It seems that modern browsers (IE9, FF4, Chrome) and client processing power are primed to exploit this standard for tangible savings in server CPU power and bandwidth on large scale properties. Am I missing something? The negative aspects I'm aware of include * additional rendering time * additional assets required on uncached page load * additional layer of complexity * noticably less developer experience than server-side template techniques The benefits I perceive include * distributed template composition (offloaded on the client) * caching of common template fragments offloaded on the client * logical separation of document structure and data * well-documented web standard supported by all modern browsers Finally, although I know it's impossible to predict the future, I am curious to know opinions on whether or not client-side XSLT's day will come. With interest in HTML5 driving users to upgrade their browsers and developers to explore new techniques, I would say yes. How about you? Thanks in advance, Casey

• Database designing for a bug tracking system in SQL

  - by Yasser

  I am an ASP.NET developer and I really dont do such of database stuff. But for my open source project on Codeplex I am required to setup a database schema for the project. So reading from here and there I have managed to do the following. As being new to database schema designing, I wanted some one else who has a better idea on this topic to help me identify any issues with this design. Most of the relationships are self explanatory I think, but still I will jot each one down. The two keys between UserProfile and Issues are for relationships between UserId and IssueCreatedBy and IssueClosedBy Thanks

• When to choose LAMP over ASP.NET?

  - by Carlo

  Hello. A friend wants to start a dating website, she wants me to help her. We still haven't discussed on what platform it'll be developed, but I'm thinking she'll suggest LAMP to save a buck (which is one reason already to chose over ASP.NET already). If the dating website does well, it'll potentially hold a large amount of data (I'm not sure if this would be another reason to consider either ASP.NET or LAMP). Anyway, I ask this from an ASP.NET developer point of view. I have very little, almost null experience with LAMP, and I don't like it very much either, so if she decides to go with PHP odds are I won't help her. So what would be some good points to bring up when deciding which platform to develop on? Please be objective, I don't want this to be argumentative or anything, try to stick to facts, not opinions alone. Thanks!

• Visual Studio - 'Browse UDDI Servers' -> 404 ?

  - by southof40

  Hi - I have a ASP.Net application which implements a web service. Within the ASP.Net application there's a test script which consumes the web service and it all works etc. I have built a .NET console application and want to 'Add a Web Reference' so that the console app can consume the web service provided by the ASP.NET application. When I use the 'Browse UDDI Servers on the local network' to do that any plausible URL I use results in a 404. I'm guessing I need to do something to my ASP.Net application so that it acts as an UDDI server ? Does anyone know what ? Update I just wanted to clarify something - I'm not desperate to use UDDI it just seems that's the only option in my circumstances which are : I'm actually doing this for another developer who is used to using Visual Studio to do this stuff The other developers system will need to run on another machine within the same network.

• file path of a MenuItem target with cmdOpen action

  - by maranas

  I am trying to acquire the file path of an item within the NSMenuItem object. Using [objectname action] i am able to properly acquire the action (cmdOpen). But [objectname target] returns a null value. According to the documentation in the apple developer website, if the value is null, the action is sent to the first-responder. I want to be able to dynamically access the file path of the target file. Is there a way to do this without changing the program design?

• how to install mysqlDb for MySQL and Python ON WINDOWS

  - by Spikie

  I AM A NET DEVELOPER TRY TO INSTALL MYSQLDB FOR PYTHON I KEEP HAVING THIS ERROR MESSAGE raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb I AM FOLLOWING THIS INSTRUCTION FROM THIS SITE <"http://sourceforge.net/project/shownotes.php?release_id=303257" I DO NOT UNDERSTAND THESE LINES Windows ....... C:... python setup.py install C:... python setup.py bdist_wininst The latter example should build a Windows installer package, if you have the correct tools. In any event, you must have a C compiler. Additionally, you have to set an environment variable (mysqlroot) which is the path to your MySQL installation. In theory, it would be possible to get this information out of the registry, but like I said, I don't do Windows, but I'll accept a patch that does this. I HAVE BEEN SEARCHING FOR ANSWER ALL DAY PLEASE DO ANYBODY REALLY KNOW HOW TO DO THIS OR AT LEAST POINT ME IN THE RIGHT DIRECTION???? THANKS and what is the c compiler for???????

• Code Profiling in the Windows Sidebar Environment

  - by Matt

  Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

• Propietary modules within GPL and BSD kernels

  - by Francisco Garcia

  Since the Linux kernel is GPL and not LGPL I suppose that it is illegal to link proprietary code to it. How does the industry circumvents this? I would expect that the GPL license will force any developer to release under GPL driver and/or kernel module. Maybe I am confused and implementing a new module is not really linking against the kernel code ??? How do companies deal with this? Maybe linking the other way around (from kernel to their binaries)? On the other hand there is the BSD kernel. Where you are free to link protected IP. Can you get a better design implementing your drivers within a BSD kernel? Is there any design restriction when implementing drivers for GPL kernels?

• What is your ratio Bug fixing vs Enhancements ?

  - by Newtopian

  In the spirit of this question I wanted to have a sense of what is the proportion of time split between fixing bugs and implementing new features. If possible try to give an estimate for the product as a whole as opposed to individual developer stats and try to make an average over the course of a typical year. Do provide a general descriptive of the product/project to allow comparison. Specifically : Maturity of project Is it still actively developed or strictly in maintenance ? Size estimate of the product/project Size of team developing it (all inclusive) What is your team score on the Joel test. Ex : approx 80% time spent bug fixes 20% new stuff Mature software (20 years old) Actively developed 1.5M Line of Text, approx 700k - 900k LOC 12-15 actively coding in it. we got 5/12 for sure, some would say 7/12.

• How to develop a Google Gadget compatible server

  - by Peter Stegnar

  I am going to develop a Google Gadget container site, that will be able to host OpenSocial compatible widgets (that I believe are Google gadgets, too, right?). Do you have any guidance where to start? I know that the good start is the iGoogle Developer Home site and that framework what I would like exists - Shindig, but is little clumsy. Tutorial links do not work, for start. Do you think it would be wise to use Shindig? Maybe just for a start and then develop any customizations, if needed? Or would be wiser to start from scratch? So where to start? Do you have any advices, tips or other useful resources to get on faster with this topic? I guess I can start with Compliance - Gadget Server?

• Copying (or recovering) a .PFX password to another machine?

  - by Adam Robinson

  First things first, I'm aware of all of the finger-wagging potential that this question provides. However, I'm attempting to help out a friend with a project so I haven't been part of the decision making process thus far. I'm attempting to set up a new development machine, but one of the projects is signed with a .PFX key that's password protected and the original developer does not remember the password. The current development machine can open and build the project just fine, so I'm wondering if there is any way either to copy or to recover the saved password that Visual Studio is using on the original box so that the file can be used on the new box. Signing with a new file is obviously an option, but one that we'd prefer to avoid. Does anyone know of a way either to recover or copy the credentials for this file to a new machine?

• Resharper and var

  - by Refracted Paladin

  I have Resharper 4.5 and have found it invaluable so far but I have a concern; It seems to want to make every variable declaration implicit(var). As a relativly new developer how much should I trust ReSharper when it comes to this? Take the below code snippet from a method that Paints Tab Headers. TabPage currentTab = tabCaseNotes.TabPages[e.Index]; Rectangle itemRect = tabCaseNotes.GetTabRect(e.Index); SolidBrush fillBrush = new SolidBrush(Color.Linen); SolidBrush textBrush = new SolidBrush(Color.Black); StringFormat sf = new StringFormat { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center }; Resharper wants me to change all 5 of those to var. I have read the following similar post,Use of var keyword in C#, but I would like to know from a Resharper standpoint. Thanks!

• Updating a TableView with a WebService and Saving to CoreData

  - by jcady

  I am working on a project where I have a table view that is currently updated via a web request that returns XML. I implemented -(int)numberOfRowsInTableView:(NSTableView*)tv and -(id)tableView:(NSTableView *)tv objectValueForTableColumn:(NSTableColumn*)tableColumn row:(int)row in my XML parsing class, and have the table updated with the data that is pulled down from the server. I want to save the data that is pulled down using Core Data, so that the table can be saved/loaded. Then later on application start when the web request is made, it will only add data that is not already present. (The XML is sorted by release date, so later I will check to see which release dates are not loaded up from the Core Data store, and only load newer entries.) How would I go about implementing this? I am a very new Cocoa developer, but have gone through the entire Hillegass book. Thanks so much.

• When do you learn from your mistakes?

  - by smayers81

  When are you supposed to learn from your mistakes in coding / design? Is it something you take with you to the next project or do you learn in the middle of your current one, sacrificing consistency for cleaner, more well-informed code? For example, my application can be distinctly demarcated down two lines of business -- say one side is for sales and the other is for marketing. Both are somewhat tied together, but as far as the team structure, use cases, developers, etc. the app consists of the Sales code and the Marketing Code. Now, say the Sales code went in first and while good-intentioned, made some bad mistakes. Should the Marketing Code follow suit and make the same mistakes for the sake of consistency or should Marketing architects and designers instead learn from the mistakes that Sales made and developer a cleaner codebase, even though Sales and Marketing are in the exact same system? Basically, do you learn from your mistakes while in a project or do you continue to pile crap on top of crap?

• @font-face Not Working on Other Computers

  - by Raphael Essoo-Snowdon

  Hey Guys, I've been working on my first HTML5/CSS3 site, and it's been going well for the most part. Totally loving the new @font-face property, and it works perfectly on my machine. The problem I'm having is when previewed on another device (computer, ipad, iphone), it doesn't seem to be recognising the @font-face property and uses the fallback font instead. Site link: http://williamben.com/ Here's the CSS I'm using: @font-face { font-family: 'League Gothic'; src: url('_/type/league_gothic.otf') format('otf'); } Any help would be appreciated. Thanks in advance.

• Interface Builder and Xcode integration not working

  - by Martin Cote

  After having installed the iPhone SDK 3.1.2, Interface Builder is not in sync with Xcode anymore. The light indicator at the bottom of the XIB window is grey. IB doesn't see any files from the Xcode project. Xcode is always open when I start IB. I tried rebooting. No luck. I tried removing the preferences files for Xcode/IB. No luck. I tried reinstalling Xcode/IB. Still no luck. This page explains how IB monitors the changes in Xcode. While it was an interesting read, it didn't provide any help about how to investigate my problem. Any help would be appreciated. EDIT Here's additional information. I enabled the debug logs for launchd, and I noticed the following line that appears every time Interface Builder is started: [0x0-0x1b01b].com.apple.InterfaceBuilder3[315]: Couldn't open shared capabilities memory GSCapabilities (No such file or directory) This really seems to be related to my issue.

• C code autocomplete in Eclipse

  - by Ittai

  Hi, I'm a Java developer and I've downloaded the Eclipse for C (course purposes) and to my amazement the control+space shortcut (for autocomplete) did not work. I've created a new project and a new class using the wizzards and started to type "print" and then tried to find an autocomplete feature. After a bit of googling I arrived at C/C++-Editor-Content Assist-Advanced and there I verified that Help proposals,Parsing-based proposals and Template proposals options were checked. I then went over to the Keys preferences page using the link at that page and entered a binding for all relevant content assist from before C\C++ Content Assist (type...) and chose in the When box the C\C++ Editor option. But alas no autocompletion was offered. Can someone please point me to the right direction? Thanks, Ittai

• LocalUser access for WCF hosted in IIS

  - by Eugarps

  I have tried every combination to allow unauthenticated access to WCF as in "LocalUser" accounts, in IIS without success. Here is what I've most recently tried: wsHttpBinding with Message security and mode set to "None". IIS anonymous access enabled, all others disabled, folder level access at default (but granted read access to "Users" which is all users in our domain). I understand I may not have provided enough information to solve the issue, but perhaps somebody can point me in the right direction - is this likely to be a IIS configuration issue or a WCF configuration issue... if WCF, is it likely to be a client level or server level issue? The error I get when attempting to access here is "User is not authenticated". We have ASMX services in the domain which are behaving properly, I am the first developer using WCF here.

• How convince other developers not to ignore Exceptions?

  - by Mnementh

  Recently I encountered a bug in an application I took over from another developer. I debugged for the reason and over an hour later I realized, that the problem wasn't the code producing the exception, but some code executed before this returning wrong data. If I dived into this, I encountered the following: try { ... } catch (XYException e){} If the Exception would have been propagated (a change I did), I would have found the reason for the bugs in a few minutes, as the stacktrace had pointed me to the problem. So how can I convince other developers to never catch and ignore exceptions in this way?

• Learning web development as I go

  - by Matt Luongo

  Hey everybody, I've been seriously preparing to take the entrepreneurship leap. I've got a great partner, and we're going to take on some minor funding, and do the thing. Our product is web-based- I'll deem it YAWA (Yet Another Web Application). Both my partner and I have database and web development experience, and I've had a front-end developer in mind for a while. Except, well- he just bowed out. I know a fair amount about the associated technologies (XHTML, CSS, Javascript and some JQuery) interface-side, but I've never had to deal with real-world scenarios, eg cross-browser design. Am I going to be able to survive without this guy? Is it realistic to believe that I can learn the details as I go?

• Using Windows media foundation

  - by Martin Beckett

  Ok so my new gig is high performance video (think Google streetview but movies) - the hard work is all embedded capture and image processing but: I was looking at the new MS video offerings to display content = Windows Media Foundation. Is anyone actually using this ? There are no books on the topic. The only documentation is a developer team blog with a single entry 9 months old. I thought we had got past having to learn an MS api by spying on the com control messages! Is it just another wrapper around the same old activeX control?

• Using makecert for Development SSL

  - by John

  Here's my situation: I'm trying to create a SSL certificate that will be installed on all developer's machine's, along with two internal servers (everything is non-production). What do I need to do to create a certificate that can be installed in all of these places? Right now I've got something along these lines, using the makecert application in Microsoft Visual Studio 8\SDK\v2.0\Bin: makecert -r -pe -n "CN=MySite.com Dev" -b 01/01/2000 -e 01/01/2033 -eku 1.3.6.1.5.5.7.3.1 -ss Root -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 mycert.cer However, I'm not sure as to how to place this .cer file on the other computers, and when I install it on my local machine IIS, everytime I visit a page via https:, I get the security prompt (even after I've installed the certificate). Has anyone done this before?
