  • Pitfalls to avoid when starting a software company.

    - by Imagist
    It's been my goal to start my own software company basically since I started programming HyperCard on System 6 back in elementary school. Recent changes in my job situation have convinced me that I should be pursuing this goal more actively. My question is, what are some pitfalls that I should avoid when starting a software company? A lot of companies fail and I'm sure there are a lot of reasons. As a side-request, it would be particularly helpful if you could tell me a little about your own experience with starting a software company or being a part of a startup, so I know how you know what you know.

  • Software Protection: Shuffeling my application?

    - by Martijn Courteaux
    Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

  • Experience using IRC to coordinate software development?

    - by momeara
    I am part of a growing software project with at least 200 active developer in 10 locations. I would like to set up an on-line chat forum for developers because I think it would help to coordinate efforts. We have an email mailing list but I feel like some questions or announcements are too informal to send to everyone while mentioning it in a chat forum might be a useful community resource. I have never participated in a software project that used an on-line chat forum so I would like to hear about peoples experiences. I am particularly interested in technical issues: Use of IRC vs. alternative platforms; how to manage access, eg. for developers only, allowing users to participate; the value of requiring certain announcements to be made on the chat forum eg who is resolving broken builds etc. If I pitch the idea to the community I would like to have some good arguments why it would be a good idea and some prospective of its usefulness in other software projects.

  • Most common software development mistakes

    - by hgulyan
    Inspired by Dealing with personal failure, I remembered my own failed software development experience. Finally I agreed to rewrite existing application. It took me less than a week to rewrite existing app and more up to 2 months to write from zero my own. That 2 months were really hard and interesting. It was my first big software development process. I researched almost everything concerning to my application. Read Code Complete. Even some articles on how to create user interface. Some psychology stuff. Typography, Colors. DAL, DB Structure, SOA, Patterns, UML, Load testing etc. I hope, that after a month or 2 I would get opportunity to continue working on my failed project, but before that, I would like to ask: What are common mistakes in software development? What you shouldn't do in any case?

  • Custom 403 Error page not showing

    - by Rahul Sekhar
    I want to restrict access to certain folders (includes, xml and logs for example) and so I've given them 700 permissions, and all files within them 600 permissions. Firstly, is this the right approach to restrict access? I have a .htaccess file in my root that handles rewriting and error documents. There are two pages in the root - 403.php and 404.php - for 403 and 404 errors. And I have these rules added to my .htaccess file: ErrorDocument 404 /404.php ErrorDocument 403 /403.php Now, the 404 page works just fine. The 403 page does not show when I try to access the 'includes' folder - I get the standard apache 403 error page instead, saying 'Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.' However, when I try going to the .htaccess file (in the web root) in my browser, I get my custom 403 error page. Why is this happening?

  • Apache: how to set custom 401 error page and save original behaviour

    - by petRUShka
    I have Kerberos-based authentication with Apache/2.2.3 (Linux/SUSE). When user is trying to open some url, browser ask him about domain login and password like in HTTP Basic Auth. If user cancel such request 3 times Apache returns 401 Authorization Required error page. My current virtual host config is <Directory /home/user/www/current/public/> Options -MultiViews +FollowSymLinks AllowOverride None Order allow,deny Allow from all AuthType Kerberos AuthName "Domain login" KrbAuthRealms DOMAIN.COM KrbMethodK5Passwd On Krb5KeyTab /etc/httpd/httpd.keytab require valid-user </Directory> I want to set nice custom 401 error page with some instructions for users. And I added such line in virtual host config: ErrorDocument 401 /pages/401 It works, when user can't authorize apache redirects him to my nice page. But Apache doesn't ask user login\password as it did before. I want this functionality and nice error page simultaneously! Is it possible to make it works properly?

  • How to set up custom 401 error page or redirect in WSS3 SP2

    - by Stacy Vicknair
    I've got a WSS3 sharepoint site that requires windows authentication both in IIS and via the Sharepoint site. What I would like to do is in the case that a user does not provide valid AD credentials they are redirected to a custom error page. Currently, if the user immediately hits cancel when prompthey will see a plain text response of "401 UNAUTHORIZED". If they make an attempt and then hit cancel they instead see a blank page. I have looked into several options such as customErrors, httpModule interception (only saw examples for this after the user is authenticated), IIS Url rewrites (didn't see how this could help). Is there a good way to do this?

  • Will you install software on the same partition as Windows system?

    - by Tim
    I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

  • Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth?

    - by DeveloperDon
    Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth? Perhaps this seems a little exotic, but it seems like a function that includes message calls or even method invocations on other objects could be automatically converted to a sequence diagram given that it is not hard to do manually. Similarly, when a sequence diagram is modified, based on the message name and type of message, should it not be possible to add a message or method to the calling object?

  • What is better Ubuntu Tweak or Ubuntu Software center?

    - by S B
    Ubuntu Tweak has served me very well over the past few release cycles, but there seems to be more and more of an overlap between Ubuntu Tweak and the Ubuntu Software Center. I wanted to know whether these two great apps are headed for a head-to-head crash (which would be a shame for the Ubuntu community) or is there some way for the two projects to complement each other, integrate and make my favorite distribution even better? Happy new year to everyone.

  • How to process payments for a software (activation code)?

    - by jsoldi
    I want to sell software online and I need an easy to implement payment processing system. What I'm actually going to be selling is an activation code (one per purchase) that would activate the trial version of a product. I was about to use this one but I just found out that people without a paid email account (not hotmail or yahoo) can't process their orders, which I'm sure would discourage many, if not most, of the possible buyers.

  • What are the alternatives to fixed-price or time-and-materials contracts for software development?

    - by Fortuity
    Where can I learn more about pros/cons of various pricing models for software development? Proponents of agile methodology suggest approaches such as multi-stage contracts, target cost contracts, target schedule contracts, shared benefit contracts, variable scope contracts (http://poppendieck.com/agilecontracts.htm). I'm looking for opinions, experience, case studies or informed discussion of these approaches.

  • Learn Lean Software Development and Kanban Systems

    - by Ben Griswold
    I did an in-house presentation on Lean Software Development (LSD) and Kanban Systems this week.  Beyond what I had previously learned from various podcasts, I knew little about either topic prior to compiling my slide deck.  In the process of building my presentation, I learned a ton.  I found the concepts weren’t very difficult to grok; however, I found little detailed information was available online.

  • Implementing Custom Software or Using Ready Softwares at Industy at Machine Learning Area? [closed]

    - by kamaci
    I am studying on Machine Learning and its implementations. I have different choices in front of me for my future. Testing algorithms by some tools as like Weka and finding best approach and after that implementing it(maybe with using some libraries at Machine Learning) On the other hand I see that there are softwares as like SPSS, SAS etc. Instead of improving myself like that should I learn that kind of programs. Do I reinventing the wheel or if I improve myself and implement custom solutions to customers then can I be a part of industry?
