• Font display issue (Mac OS X)?

  - by avenas8808

  I used a font manager on Mac OS X, for additional fonts in my graphic design projects without installing them to the fonts folder (I think that's how it works) - using Font Book and Font Explorer X Version 1.2.3 on OS X 10.6. Most fonts work fine, but Interstate has a problem: Interstate Regular is installed, but for some reason it's probably not seeing it; it's seeing all the Bold and Condensed versions fine. In the above image, it displays the second font as Interstate Regular, but it isn't that font... why? Also, how do I reset the system fonts folder back to the default-installed fonts (I think it's in the library folder) if worst comes to worst, and is using a font manager on Mac or Windows a good idea? I don't want to wreck my system, fairly new to using Mac, especially OS X, so any help would be gratefully accepted.

• Designing a system with different business rules for different customers

  - by user1595846

  My company is rewriting our proprietary business application. The current architecture is poorly done and inflexible. It is coded more procedural oriented as opposed to object oriented. It has become difficult to maintain. Our system is a web application written in .Net Webforms. I am considering ASP.Net MVC for the rewrite. We intend to rewrite it with a good, solid architecture with the goal of maintainability and reusable classes for some of our other systems and services. We would also like the system to be customizable for different customers in the event that we market the system. I am considering redesigning the system based on the layered architecture (Presentation, Business, Data Access layers) described in the Microsoft Patterns and Practices Application Architecture Guide. http://msdn.microsoft.com/en-us/library/ff650706.aspx Hopefully this isn't too open ended, but how would you recommend allowing for different business logic/rules for different customers? I'm aware of Windows Workflow Foundation, but from what I've read about it, it seems many business rules could be too complicated to handle there. Also, Can anyone point me to where I can download an example of a .net solution that is based on the Application Architecture Guide? I have already downloaded the Layered Architecture Solution Guidance and the Expense Sample on codeplex. I was looking for something a bit larger and more robust that I could step through the code and see how it works. If you feel there are better architectures to base our redesign on please feel free to share. I appreciate your help!

• Should I make a seperate unit test for a method, if it only modifies the parent state?

  - by Dante

  Should classes, that modify the state of the parent class, but not itself, be unit tested separately? And by separately, I mean putting the test in the corresponding unit test class, that tests that specific class. I'm developing a library based on chained methods, that return a new instance of a new type in most cases, where a chained method is called. The returned instances only modify the root parent state, but not itself. Overly simplified example, to get the point across: public class BoxedRabbits { private readonly Box _box; public BoxedRabbits(Box box) { _box = box; } public void SetCount(int count) { _box.Items += count; } } public class Box { public int Items { get; set; } public BoxedRabbits AddRabbits() { return new BoxedRabbits(this); } } var box = new Box(); box.AddRabbits().SetCount(14); Say, if I write a unit test under the Box class unit tests: box.AddRabbits().SetCount(14) I could effectively say, that I've already tested the BoxedRabbits class as well. Is this the wrong way of approaching this, even though it's far simpler to first write a test for the above call, then to first write a unit test for the BoxedRabbits separately?

• Sub-systems in game engines

  - by Hillel

  So here's the problem- I'm writing my own engine library, and it works fine with stuff like menus and the actual game screen. The thing is, I can't really figure out how to integrate something like an intro or dialogue preceding certain levels into this system. Let's look at another example- say I have a game-specific engine which gets a Level object and runs it. Engine would have its own collision and physics system, all hard coded. Now, what if at some point in a level, I want the player to enter a mini-game with different rules? How do I morph the Engine class to support these sub-systems without having to deal with their code all the time (as in: if(regular game) ... else if(mini game) ...)? And what if I want an intro animation at the start of a level, and I want the player to be able to assume control of his character once the animation ends, do I implement the animation into the Engine class itself? Or maybe I need to run another class, CutScene, and when it ends, it calls Engine and starts the level? What if I want to add a dialogue system, where at the start of each level there's a short dialogue and the player can't control his character, and once it ends, he can? Would I then run the dialogue code inside the Engine code? Maybe these sub-systems should all be scripted? I don't know anything about scripting, is it necessary for this kind of situation? Any help would be appreciated.

• What are some techniques I can use to refactor Object Oriented code into Functional code?

  - by tieTYT

  I've spent about 20-40 hours developing part of a game using JavaScript and HTML5 canvas. When I started I had no idea what I was doing. So it started as a proof of concept and is coming along nicely now, but it has no automated tests. The game is starting to become complex enough that it could benefit from some automated testing, but it seems tough to do because the code depends on mutating global state. I'd like to refactor the whole thing using Underscore.js, a functional programming library for JavaScript. Part of me thinks I should just start from scratch using a Functional Programming style and testing. But, I think refactoring the imperative code into declarative code might be a better learning experience and a safer way to get to my current state of functionality. Problem is, I know what I want my code to look like in the end, but I don't know how to turn my current code into it. I'm hoping some people here could give me some tips a la the Refactoring book and Working Effectively With Legacy Code. For example, as a first step I'm thinking about "banning" global state. Take every function that uses a global variable and pass it in as a parameter instead. Next step may be to "ban" mutation, and to always return a new object. Any advice would be appreciated. I've never taken OO code and refactored it into Functional code before.

• Macbook Pro 2.2ghz 2011 (OSX 10.6.7) problem with NTFS 3G

  - by James

  I installed NTFS 3G but now get the following error message when I try to plug in my external drive. I also get it on startup about my Windows partition. Uninstall/ reinstall does not work. NTFS-3G could not mount /dev/disk1s1at /volumes/freeagent GoFlex Drive because the following error occured: /library/filesystems/fuse.fs/support/fusefs.kext failed to load- (libkern/kext) link error; check the system/ kernel logs for errors or try kextutil(8). The MacFUSE file system is not available (71) Any help would be great. I'd hope to avoid reinstalling OS X if possible!

• Entity Framework and layer separation

  - by Thomas

  I'm trying to work a bit with Entity Framework and I got a question regarding the separation of layers. I usually use the UI - BLL - DAL approach and I'm wondering how to use EF here. My DAL would usually be something like GetPerson(id) { // some sql return new Person(...) } BLL: GetPerson(id) { Return personDL.GetPerson(id) } UI: Person p = personBL.GetPerson(id) My question now is: since EF creates my model and DAL, is it a good idea to wrap EF inside my own DAL or is it just a waste of time? If I don't need to wrap EF would I still place my Model.esmx inside its own class library or would it be fine to just place it inside my BLL and work some there? I can't really see the reason to wrap EF inside my own DAL but I want to know what other people are doing. So instead of having the above, I would leave out the DAL and just do: BLL: GetPerson(id) { using (TestEntities context = new TestEntities()) { var result = from p in context.Persons.Where(p => p.Id = id) select p; } } What to do?

• mac osx software always order files alphabetically rather than by type.

  - by george

  i have noticed many mac applications sort the files alphabetically rather than by type. a good example would be coda by panic.com the files in the file menu are organized alphabetically, i requested for them to add the feature to organize files by type and they've said that its a finder thing. so i went in search to look at other applications to see if they were organizing by type i noticed dreamweaver cs4 had this same problem and now including dreamweaver cs5. there has to be something in the mac that does this and that i can modify. i played with spotlight and it now displays its files by type (thinking thats what i can do) but it didnt take affect in other applications. what library are these applications using to display a file menu for its files?

• Corrupted file, hard drive test?

  - by all-R

  Hi guys, I'm currently on a macbook with a 1TB external hard drive connected trough a USB hub wich is connected on my macbook. The problem is, my disk, wich is partitioned in 2 (one HFS+ and one NTFS) keeps getting corrupted, recently it was my HFS+ partition, I could not repair it using the Apple's Disk utility, but was able to backup my files. Is it synonym that my hard drive is failing? Is it because of my USB hub? I also keep all my iTunes library on my external HD (HFS+ partition), and did a lot of transfer lately, adding files, removing etc. the last time, my partition got corrupted after a lot of deleted items. If anybody has an idea of what to check first, what could cause the problem, I would appreciate it :) Thanks!

• How should I start refactoring my mostly-procedural C++ application?

  - by oob

  We have a program written in C++ that is mostly procedural, but we do use some C++ containers from the standard library (vector, map, list, etc). We are constantly making changes to this code, so I wouldn't call it a stagnant piece of legacy code that we can just wrap up. There are a lot of issues with this code making it harder and harder for us to make changes, but I see the three biggest issues being: Many of the functions do more (way more) than one thing We violate the DRY principle left and right We have global variables and global state up the wazoo. I was thinking we should attack areas 1 and 2 first. Along the way, we can "de-globalize" our smaller functions from the bottom up by passing in information that is currently global as parameters to the lower level functions from the higher level functions and then concentrate on figuring out how to removing the need for global variables as much as possible. I just finished reading Code Complete 2 and The Pragmatic Programmer, and I learned a lot, but I am feeling overwhelmed. I would like to implement unit testing, change from a procedural to OO approach, automate testing, use a better logging system, fully validate all input, implement better error handling and many other things, but I know if we start all this at once, we would screw ourselves. I am thinking the three I listed are the most important to start with. Any suggestions are welcome. We are a team of two programmers mostly with experience with in-house scripting. It is going to be hard to justify taking the time to refactor, especially if we can't bill the time to a client. Believe it or not, this project has been successful enough to keep us busy full time and also keep several consultants busy using it for client work.

• using Team foundation server

  - by joe

  I am using Team foundation server / visual studio as a client, to manage my visual foxpro source code. everytime i "checkout for edit" all my folders and files are read only and when i open my projects, it is like if the project is opened for the first time, asking me if i would like to set the current path as the default path... this is causing other serious problems as bad reference to "missing library files", which are actually not missing. i know Visual foxpro is old stuff...i hope someone who went through the same errors could help me out. thanks a lot guys

• Psexec issue when running an application on a Windows Server 2008 R2 machine from a 2003 R2 machine

  - by Vermin

  I am trying to run an application on a Windows Server 2008 R2 machine from a Windows Server 2003 R2 machine using a batch file with the following line of code in a batch file: psexec \\nightmachine -u DOMAIN\User -p Password -i "C:\FilePath\Application.exe" argument1 argument2 The application fails to run correctly when started using psexec, but the application will run correctly if I have logged into the nightmachine with the same user and started it from its file path via cmd. I have been able to get hold of the error returned in the application from its log and the exception returned is the following: System.DllNotFoundException: Unable to load DLL 'rasapi32.dll': A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A) After searching for that error code on the net, there are a lot of posts saying that this is caused by file corruption, but I cant see why that would be the case as the application will run normally when not being run from psexec. (the user is an administrator on both machines) Can anyone please help me on this? If any more information is needed to help solve this issue then please ask and I will do my best to post it.

• Why can't I compile this version of Postfix?

  - by Coofucoo

  I just installed postfix 2.7.11 in Ubuntu server from source code. I do not use the ubuntu own one because I need the old version. I found a very interesting problem. Before, in both CentOS 5 and 6, I can build the source code without any problem. But, in Ubuntu server 12.04 is totally different. I got the following problems: dict_nis.c:173: error: undefined reference to 'yp_match' dict_nis.c:187: error: undefined reference to 'yp_match' dns_lookup.c:347: error: undefined reference to '__dn_expand' dns_lookup.c:218: error: undefined reference to '__res_search' dns_lookup.c:287: error: undefined reference to '__dn_expand' dns_lookup.c:498: error: undefined reference to '__dn_expand' dns_lookup.c:383: error: undefined reference to '__dn_expand' Yes, this reason is obviously. I just search related library and add it to the makefile. It works. The question is why? What is the difference between Ubuntu Server and CentOS? One possibility is gcc and ld version. Ubuntu server use different version of gcc and ld with CentOS. But I am not sure.

• How Can I Edit Google Chrome's 'History Provider Cache' File?

  - by dissolved

  I'm interested in editing (not completely deleting) contents of some of Google Chrome's cache files. In particular, the 'History Provider Cache' (found in ~/Library/Application Support/Google/Chrome/Default on Mac). As this other question suggests, it appears to simply be a SQLite file. Unfortunately, when I try to open it using a SQLite browser (MesaSQLite) I'm asked for an encryption key. So, I'd welcome any suggestions on how to either (1) determine the encryption key, or (2) an alternate way to edit this file. The end goal is to be able to remove specific annoying suggestions in the Omnibar. I've read countless other techniques, but none seem to remove suggestions that have the clock icon next to it. Some say deleting this file entirely will do the trick (and I imagine it will), but I don't wish to trash my entire browsing history. I find most of the suggestions to be useful and helpful, and I'd like to preserve that.

• Dropbox context menu missing in OS X

  - by slhck

  Problem My Dropbox context menu is missing in OS X Snow Leopard (10.6.8). While the Dropbox service runs normally, Finder doesn't show the icons and also doesn't give me the ability to browse files on the website or copy the public link. What I've tried Removed ~/.dropbox and ~/Dropbox/.dropbox.cache Reinstalled Dropbox.app (both 1.4.7 stable and 1.5.0 experimental), went through the setup again Restarted Finder Logged out and back in All of these I've done over and over again, in random permutations. I've made sure that Dropbox appears in the Login Items under my Account (and I've never touched that) I don't know if ~/Library/Contextual Menu Items is missing the Dropbox plugin or if there shouldn't be one after all. In any case, I can't get the icons or the menu to appear.

• Explorer image thumbnails are grey/incomplete/partial

  - by Craig620

  I have recently noticed a problem on my Win7 x64 Home machine. When navigating the pictures library, I run across a fair amount of thumbnails that are grey and only partially rendered. This is not not the absence of thumbnails caused by "always show icons, never thumbnails" checkbox, and is a local drive, have seen many other posts for those issues... I've run cleanmgr for thumbnails, and also manually deleted the .db files from %LOCALAPPADAT%\Microsoft\Windows\Explorer. That did actually fix one thumbnail once (while preparing this post) but in general it doesn't work. Why do specialized imaging programs not have this problem, but Explorer does? How do you fix Explorer? It's very annoying!

• I Can't run the Netbeans but I installed successfully

  - by David

  I'm new to Ubuntu as well as Netbeans. I installed Netbeans, and I've made sure to install all the JDKs and JREs I could find. It installed without errors. I also saw this question and made sure I followed all the instructions there as well. I never got any error messages of any kind. So far as I know, it installed okay. However, when I try to run Netbeans, I get the message in the bottom of the Netbeans IDE like this: ant -f /root/NetBeansProjects/samp1 -Djsp.includes=/root/NetBeansProjects/samp1/build/web/one.jsp -DforceRedeploy=false -Dclient.urlPart=/one.jsp -Ddirectory.deployment.supported=true -Djavac.jsp.includes=org/apache/jsp/one_jsp.java -Dnb.wait.for.caches=true run /root/NetBeansProjects/samp1/nbproject/build-impl.xml:774: The libs.CopyLibs.classpath property is not set up. This property must point to org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part of NetBeans IDE installation and is usually located at <netbeans_installation>/java<version>/ant/extra folder. Either open the project in the IDE and make sure CopyLibs library exists or setup the property manually. For example like this: ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar BUILD FAILED (total time: 0 seconds)

• Best way: restructure an existing Team Foundation Server (TFS) solution

  - by dhh

  In my department we are developing several smaller AddOns for some unified communication server. For versioning and distributed development we use a Team Foundation Server 2012. But: there is only one large TFS solution for all of our applications and libraries: Main Solution Applications App 1 App 2 App 3 Externals Libraries Lib 1 Lib 2 Tools The "Application" path contains all main applications. Those are not depending on each other, but they depend on the Libraries and Externals projects. The "Externals" path contains some external DLLs referenced in our Applications and Libraries. The Libraries path contains commonly used libs (UI templates, Helper classes, etc.). They do not depend on each other and they are referenced in the Libraries and the Tools projects. The Tools path contains some helper programs like setup helpers, update web services, etc. Now, there's some major points why I'd like to change this structure: We can't use server builds. It's uncomfortable to manage TFS scrum management with sprints, impediments, etc. with a solution structure like that. Every developer always has access to all projects in the solution. A complete build lasts too long if one accidentally hits [F6] in Visual Studio... What would you change in this solution? How would you break those projects into smaller Solutions, how should those solutions be structured. My first approach would be, to create one TFS project for each Application, Library and Tool. But how can I ensure that e.g. App 2 always contains the newest version of Lib 1? Do I have to monitor changes on Lib 1 and update App 2 manually as soon as the Lib changes? Or can I somehow force Visual Studio to always use the newest version of an external project somehow?

• How do we increase the maximum allowed HTTP GET query length in Jetty?

  - by Mike

  We are using Jetty to run an Apache Solr index. We've had some queries that have grown way beyond the previously expected maximum length, and are now having issues wehre most queries are not returning any data because the URL gets truncated. These requests are not being made through a browser, they're being made programmatically using the Apache_Solr_Service PHP library. The application is expecting queries to come in as HTTP GET requests, so simply switching to a POST will not solve this problem. How can we increase the maximum allowed HTTP GET query length in Jetty? Thanks!

• What's the best way to manage reusable classes/libraries separately?

  - by Tom

  When coding, I naturally often come up with classes or a set of classes with a high reusability. I'm looking for an easy, straight-forward way to work on them separately. I'd like to be able to easily integrate them into any project; it also should be possible to switch to a different version with as few commands as possible. Am I right with the assumption that git (or another VCS) is best suited for this? I thought of setting up local repositories for each class/project/library/plugin and then just cloning/pulling them. It would be great if I could reference those projects by name, not by the full path. Like git clone someproject. edit: To clarify, I know what VCS are about and I do use them. I'm just looking for a comfortable way to store and edit some reusable pieces of code (including unit tests) separately and to be able to include them (without the unit tests) in other projects, without having to manually copy files. Apache Maven is a good example, but I'm looking for a language-independent solution, optimally command-line-based.

• Ubuntu 11.10 w/ Cinnamon - Icons are gone and pictures do not display

  - by B U N N Y

  I'm new on this site and new to using Ubuntu and all. I currently have Ubuntu 11.10 and Cinnamon along with it. I've recently downloaded only a few applications, like the Adobe shockwave as well as a few games. After the downloads, the icons for the windows (the close, minimize, and maximize) are nothing but streaks of colours, and now just plain black, picture previews in my picture folder is gone, some icons on the panels are missing, and icons in the control center are gone. I'm sure more are gone, but that's the ones that I see often. I'm not sure what caused this to happen?? Please get back to me soon! I'm worried about what has happened. ): This is my only laptop to get online. I have no other way besides the library but that takes too long.. EDIT: Okay, I had asked my sister for some help and she helped me restore my minimize, maximize, and close button but I still haven't figured out how to show the icons in the cinnamon dock (which I have set at the top of the window) and how to have my pictures show up again. All of my pictures are just blank and I can't even preview them. They still have their file names but that is it. I'm not sure what has happened. I haven't downloaded any new apps as of the new edit.

• What exactly is bootstrap admin-template and how it is supposed to be used

  - by Leron

  So this is my second ASP.NET MVC 4 project. It's decided that for this one we will use this template and it was said in a way that I felt really stupid for not knowing how exactly this template will help us and what exactly we gain by using it. I'm used to using HTML/CSS for the UI combined with jQuery. Now it seems that instead of jQuery we will be using bootstrap which as far as I understand is just another JS library created from twitter, so if that's it then this part is clear. What I really need to clarify for myself is what exactly this theme is used for, what is offering, why one would want to use such a theme? From what I see in the live demo maybe it's just a stack of premade controls that you can use in the front end along with bootstrap.js and maybe I'm just confused because on the page is shown as much as possible just for presentational purposes. If that's right, still I wonder where I can find info for the current theme, the controls that it offers and the functionality that I get and not least - how to use it. But still those are just my assumptions. What I really need is a clarification on what exactly is this theme for, what is the advantage using it, is there a good tutorials about how to use such themes in the context of ASP.NET MVC 3+. Also any additional info about this theme and generally on using themes in ASP.NET MVC will be much appreciated.

• Why does my iTunes use so much CPU time?

  - by bikesandcode

  I have a roughly 2 year old Macbook (10.5). I have iTunes 10. When iTunes is playing MP3s, I see CPU usage of the iTunes process in the system monitor ranging from 65%-75%. When I pause the music, I see CPU usage of about 65%-75%. I do not have any visualisations going, to my knowledge I have not turned on any CPU destroying features, my music library isn't tiny, but it's hardly huge (3GB). This is mildly annoying when I'm plugged into the wall as I only have slightly longer compile times, but if I am out and about, this is a major drain on the battery. Using VLC I see CPU loads of ~= 10% at the most when listening to music and generally lower. What the heck is iTunes doing?

• How can I prevent a Windows laptop from making noise when starting up?

  - by Walkerneo

  I have a Windows 7 laptop here that makes a noise each time it starts up. I know I can disable that noise now that I'm logged on, but how could I have prevented it WHILE logging on? I remember that there was one of the function keys (F8?) that would allow you to boot into safe mode, but is there a key that will stop the startup sound? Imagine, for example, having your laptop in the library when you know the volume is all the way up - how could you log into your computer without disturbing everyone else?
