• Mailman bounces go to me, do not unsubscribe user! (MacOS Server)

  - by vy32

  I run a large mailing list (30,000 users). Every month I get a whole slew of bounces in my mailbox from the "mailing list memberships reminder" that get sent out. I thought that these were supposed to go to the program and automatically unsubscribe people, not go to me. We are running a standard unmodified MacOS Server installation. Here is a typical bounce: From: Mail Delivery System Subject: Undelivered Mail Returned to Sender To: [email protected] This is the mail system at host mail.COMPANY.COM. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster.

• Is it possible to run an old 16-bit DOS application under Windows 7 64-bit? [closed]

  - by NFX

  Possible Duplicate: Why 64 bit OS can't run a 16 bit application? How do I get 16-bit programs to work on a 64-bit Windows? Here at work my new development machine is Windows 7 64-bit (so I can use extra memory and run VMs). However I have a dilemma: it appears that 16-bit DOS programs do not run under Windows 7 64-bit. I have an old legacy program written in Clipper that I need to run periodically. I cannot access the compatibility setting as Windows 7 just greys them out.

• Can I remove a RAR file's (known) password without recompressing the archive?

  - by Abluescarab

  Long title. Anyway, I haven't been able to find an answer to this question. I know the password to the RAR file, I locked it myself, but now all I want to do is remove the password because it's too much of a pain in the butt to type it in every time. Is there a way to do this in WinRAR or an equivalent program? The only thing I knew to do was to extract it, then create a new RAR without the password. It's not a life-or-death issue, but it would be nice to know. Thanks for your time! EDIT: I just saw a bunch of related questions that appear to ask the same thing. The only solution I saw was using a DOS command to yadda yadda yadda. Here it is: How to remove password protection from compressed files Is there an easier way? Thanks again!

• Will an online degree get you a job that requires "CS or equivalent 4-year degree"? [on hold]

  - by qel

  I'm a nerdy slacker type who didn't get my life together till I was 30. I've had a real job for a couple years doing C#/SQL. I've gotten several raises, but I'm making less than most developers, and the atmosphere is ... not positive. Looking for a new job, I think my applications get thrown out because I don't have a degree. And I want to finish a Bachelor's just to feel like less of a loser. I have a lot of college credits from 1996-2003 and a low GPA, so I don't know if that's worth much. An online degree looks like a good option, but I just don't know what I should be looking at for online schools because they all look like fake degrees. If they had programs equivalent to a real Comp Sci degree, I don't think they would have weird sounding names like they do. University of Phoenix has a B.S./Information Technology-Software Engineering. DeVry has a B.S./Computer Engineering Technology program. But that's not CS, and most other things I see have even more fake-sounding names. Are these useless degrees? Some people say DeVry and UoP are acceptable, some people say they're a joke. I have enough experience now, though, that maybe all I'm missing is being able to check the box that I have a 4-year degree. Harvard Extension seems like a real degree, even if it isn't a real Harvard degree, but I'd have to live there at least 3 months, which kinda defeats the purpose of an online degree fitting around work.

• Did bittorrent sync take advantage of multiple peers

  - by NachoChip

  I am currently testing BT sync, and really like it. However, I cannot find much of the technical detail regarding to how it works. I wonder did anyone know that is the program take advantage of multiple peers connection? For example, if I have a File A(FA), which exist in Computer 1 (C1) and Computer 2 (C2). If I set up a sync from C1 and C2 to a folder in Computer 3 (C3), will I get a better sync up time because I can get FA from 2 sources at the same time (of course, assume I have enough downstream)?

• Is there any way to facilitate switching windows in Ubuntu?

  - by Ivan

  I'm just a student who received my laptop from my uncle, who's a coder, so I'm still getting used to working with ubuntu. I recently upgraded ubuntu from an earlier version, and everything seems to be pretty great. The only thing is that when I open a program, or file, or whatever, it takes up the whole screen. I can only close it by going to the far top left of my screen, or by ctrl+W. Anyways, I find it really hard to switch between programs. For example I really like to have my windows that are open to be accessible by clicking on their icon at the bottom of the screen... Great when writing or researching. Anyways, I really just want to find an easier way to switch windows. Also, I used to love the way I could cube-rotate my screen, and just drag files from one desktop to another, with compiz. Now, its sort of like flipping a coin when I switch windows, is there any way to get my desktop cube back? And yes, I have enabled all the old settings I used to use with compiz. Sorry if what I'm asking is very basic, I know how to use a computer, I'm just not really familiar with the interface! Any help is greatly appreciated.

• Cannot get Virtual PC to install on my machine

  - by Brandon

  I'm not sure what I'm doing wrong. I ran the tool to check that hardware virtualization is enabled, and it is (i7-2600). I ran the proper version of the Virtual PC download (Windows 7 Professional x64) and I can see the Windows Virtual PC (KB958559) update in my installed updates list. The .msu file runs fine without errors, but even after multiple reboots I can't actually find a trace of Virtual PC anywhere. There is nothing in program files, the start menu, or system32. Am I missing a step?

• How can I programmatically renumber pages in a PDF?

  - by Andrew

  As a graduate student, I come across PDFs of articles and book chapters on a daily basis. Sometimes these PDFs are paginated correctly internally (that is, if an article starts on page 67, the PDF starts on page 67 as well; not on page 1). When they aren't, I have to open the file in Acrobat and renumber the pages in the "Page Thumbnails" panel. I would love to be able to automate this whole process with a script (bash, Python, AppleScript, whatever) that lets me pass the first actual page number... something like fixpagination example.pdf 67. However, I cannot find any terminal-based program that can re-paginate PDFs. Neither pdftk nor PyPDF seem to be able to deal with pagination. Are there any scriptable programs that can internally re-paginate PDF files?

• windows - batch moving files to another folder/directory

  - by jdamae

  I am getting an error message to the effect of unable to move files to a single file. I am not trying to do this. What I am trying to do is move files from one folder to another folder (staging) and then deleting the original folder. If you can show me a better way to do this since I am not doing this correctly. Thank you. Here is my .cmd file: Y: move "Y:\ABC_files\*.js" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.css" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.png" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.htm" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.gif" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC.htm "C:\Documents and Settings\user\Desktop\ABC_Stage\" rmdir "Y:\ABC_files" C:\"Program Files"\"App X"\App-IDE.exe -r ABC4.run

• Access console of QNX server

  - by dhergert

  I am new to QNX (although I am familiar with Unix/Linux). This company I am working with has an old QNX (4.25) server in a server room that they remotely access via Windows terminals (Kermit via Telnet) which presents them with a text-based program. I need to get into/onto the actual box to be able to view directories, files, etc... and wondering if I can do that "remotely", along the lines of how I would SSH into a Unix box. Is there something like that in QNX? Do I need to actually hook up a keyboard/monitor to this server to be presented with a console? Would I even get a console?

• How to plan/manage multi-platform (mobile) products?

  - by PhD

  Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

• Are there design patterns or generalised approaches for particle simulations?

  - by romeovs

  I'm working on a project (for college) in C++. The goal is to write a program that can more or less simulate a beam of particles flying trough the LHC synchrotron. Not wanting to rush into things, me and my team are thinking about how to implement this and I was wondering if there are general design patterns that are used to solve this kind of problem. The general approach we came up with so far is the following: there is a World that holds all objects you can add objects to this world such as Particle, Dipole and Quadrupole time is cut up into discrete steps, and at each point in time, for each Particle the magnetic and electric forces that each object in the World generates are calculated and summed up (luckily electro-magnetism is linear). each Particle moves accordingly (using a simple estimation approach to solve the differential movement equations) save the Particle positions repeat This seems a good approach but, for instance, it is hard to take into account symmetries that might be present (such as the magnetic field of each Quadrupole) and is this thus suboptimal. To take into account such symmetries as that of the Quadrupole field, it would be much easier to (also) make space discrete and somehow store form of the Quadrupole field somewhere. (Since 2532 or so Quadrupoles are stored this should lead to a massive gain of performance, not having to recalculate each Quadrupole field) So, are there any design patterns? Is the World-approach feasible or is it old-fashioned, bad programming? What about symmetry, how is that generally taken into acount?

• How to bypass Forefront TMG for downloading from Adobe Cloud

  - by user1006272

  I hope that this question has not been asked as I've spent a couple of days googling around trying to find a solution. I have one computer that needs to download from Adobe Cloud to install applications like Photoshop etc... The issue I'm having is that Adobe uses a download manager program (AdobeApplicationManager.exe) that just keeps incrementing the time left on the download of any app like Photoshop. Is there a way to allow just the download manager from that one computer to bypass any filtering settings in Forefront TMG 2010? I have very little knowledge of servers / ISA servers / Forefront TMG and have been thrown into this position by luck I guess. Any help with this would be highly appreciated. Thanks in advance.

• Changing wallpaper depending on time of day via script or batch file?

  - by Patrick

  I want to have 2 different wallpapers that change according to time of day (6 and 22 hours respectively) and only want to display the night one after 22 hours and the day one only after 6 hours and until 22 hours. I didn't find a program that can do this after a standby, so I thought it should be easy to realize with the task scheduler running a script. Now the question is not only how to realize such a script, but also if the script should include the time checking or the task scheduler. I'm not sure what would work better with long times of the PC being in standby. I tried a few scripts already from similar questions and hoped I could modify to them to my needs, but they didn't work at all. Anyone able to help me? TIA.

• How do I develop database-utilizing application in an agile/test-driven-development way?

  - by user39019

  I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

• What tools and knowledge do I need to create an application which generates bespoke automated e-mails? [on hold]

  - by Seraphina

  I'd like some suggestions as to how to best go about creating an application which can generate bespoke automated e-mails- i.e. send a personalized reply to a particular individual, interpreting the context of the message as intelligently as possible... (This is perhaps too big a question to be under one title?) What would be a good starting point? What concepts do I need to know? I'd imagine that the program needs to be able trawl through e-mails as and when they come in, and search for keywords in e-mail content, in order to write an appropriate reply. So there needs to be some form of automated response embedded in the code. Machine learning and databases come to mind here, as I'm aware that google incorporates machine learning already in gmail etc. It is quite tricky to google the above topic, and find the perfect tutorial. But there are some interesting articles and papers out there: Machine Learning in Automated Text Categorization (2002) by Fabrizio Sebastiani , Consiglio Nazionale Delle Ricerche However, this is not exactly a quick start guide. I intend to add to this question, and no doubt other questions will spark off this one. I look forward to suggestions.

• Logging violations of rules in limits.conf

  - by PaulDaviesC

  I am trying to log the details of the programs that where failed due to the limit cap defined in the limits.conf. My initial plan was to do it using the audit system. The idea was to track the system calls related to limits in the limits.conf that where failed. However the problem with this approach is that , it is not possible to track the violations of cpu time, since that violation do not involve failure of system calls. In the case of CPU time , one thing happens is that the program which violated the cpu time will be delivered a SIGXCPU. So my question is how should I go about logging the programs that violated CPU time? Also is there any limits.conf specific logs available?

• 7 drived classes with one common base class

  - by user144905

  i have written the following code, //main.cpp #include<iostream> #include<string> #include"human.h" #include"computer.h" #include"referee.h" #include"RandomComputer.h" #include"Avalanche.h" #include"Bureaucrat.h" #include"Toolbox.h" #include"Crescendo.h" #include"PaperDoll.h" #include"FistfullODollors.h" using namespace std; int main() { Avalanche pla1; Avalanche pla2; referee f; pla1.disp(); for (int i=0;i<5;i++) { cout<<pla2.mov[i]; } return 0; } in this program all included classes except referee.h and human.h are drived from computer.h. each drived calls has a char array variable which is initialized when a member of a drived class is declared. the problem is that when i declare tow diffrent drived class memebers lets say Avalache and ToolBox. upon printing the char array for one of them using for loop it prints nothing. However if i declare only one of them in main.cpp the it works properly. and the file for computer.h is as such: #ifndef COMPUTER_H #define COMPUTER_H class computer { public: int nump; char mov[]; void disp(); }; #endif ToolBox.h is like this: #ifndef TOOLBOX_H #define TOOLBOX_H #include"computer.h" class Toolbox: public computer { public: Toolbox(); }; #endif finally Avalanche.h is as following: #ifndef AVALANCHE_H #define AVALANCHE_H #include"computer.h" class Avalanche: public computer { public: Avalanche(); }; #endif

• Force Windows 8 to search indexed files

  - by Hrvoje

  When using search files in Windows 8 (win+f) I don't get expected results. For example, I installed VLC, it's in Program Files (86) folder, and that folder is selected for indexing. Search for files (win+f) gives 0 results. If I pin to start that exe, then it's found - but I don't want to do this, that's not the point. Where does it search for files? Is there any way to specify search locations? It doesn't use Indexing Options settings, at least it seams so. Also, searching from explorer window is kinda slow - I tried entering VLC.EXE in search box (when in c:\ root), and it takes some time to give correct results. It works, but it looks like it doesn't use indexing, rather scan all files/folders, which is slow.

• Will Unity skills be interchangeable?

  - by Starkers

  I'm currently learning Unity and working my way through a video game maths primer text book. My goal is to create a racing game for WebGL (using Three.js and maybe Physic.js). I'm well aware that the Unity program shields you from a lot of what's going on and a lot of the grunt work attached to developing even a simple video game, but if I power through a bunch of Unity tutorials, will a lot of the skills I learn translate over to other frameworks/engines? I'm pretty proficient at level design with WebGL, and I'm a good 3D modeller. My weaknesses are definitely AI and Physics. While I am rapidly shoring up my math, and while Physics is undeniably interesting there's only so many hours in the day and there's a wealth of engines out there to take care of this sort of thing. AI does appeal to me a lot more, and is a lot more necessary. AI changes drastically from game to game, is tweaked heavily during development, and the physics is a lot more constant. Will leaning AI concepts in Unity allow me to transfer this knowledge pretty much anywhere? Or will I just be paddling up Unity creek with these skills?

• 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.
