  • C# code cleaning/auditing tool (stand-alone outside of the IDE).

    - by lucidquiet
    Does anyone know of a stand-alone tool for C# code cleaning/auditing that can run outside of Visual Studio IDE so as to be part of a build. Or if that isn't possible can someone provide some guidance as to how to make Visual Studio part of a build process -- by that I mean it would be nice to run the IDE's Sort and Remove unused using statements on all files as part of the build, but even better would be an exe that can read the .sln, or .csproj and do the job as part of build system. Thanks, L-

  • Aggregation, Association and Composition (examples of code given)

    - by Bukocen
    I have such a simple example: public class Order { private ArrayList<Product> orders = new ArrayList<Product>(); public void add(Product p) { orders.add(p); } } Is it aggregation or composition? I guess it's composition, because orders will be delated after delete of Order, right? Unfortunately it was a task and answer was different;/ Do you know why? second problem: public class Client extends Person { String adress = ""; Orders orders = new Orders(); public Client(String n, String sn) { name = n; surName = sn; } public String getAddress() { return adress; } public Orders getOrders() { return this.orders; } } Is it Association between Client and Orders? My teacher told me that this is association, but I was wondering why it's not a aggregation/composition - he told me that aggregation or composition occur only when one class contains few instances of different class - is that right? I guess not, because e.g. car contains ONE wheel and it's aggregation I guess? What type of relation is that and why? Greetings

  • What do I need to know before working on an IM application?

    - by John
    I'm looking into building an IM-type application using Java stack (for the server at least). I'd be interested to see any information/advice on how applications like Skype/AIM/MSN work, as well as know any technologies/APIs that might be relevant. Without giving away the idea itself, it's perhaps more akin to Google Wave than Skype, but information useful for either is very welcome. Specific points I have already thought of include: Server Vs P2P... for reasons of logging my system will require all communication to go through a central server. Is this how other IM tools work... especially when audio/video comes into the equation? Cross-communication with other systems. Are there APIs for this or do all IM providers work hard to keep their protocol secret? The nature of what I'm designing means integration could probably only be limited, but it definitely seems worthwhile from a business perspective

  • Android Static Variable Scope and Lifetime

    - by Edison
    I have an application that has a Service uses a ArrayList to store in the background for a very long time, the variable is initialized when the service started. The service is in the background and there will be frequent access to the variable (that's why i don't want to use file management or settings since it will be very expensive for a file I/O for the sake of battery life). The variable will likely to be ~1MB-2MB over its life tie. Is it safe to say that it will never be nulled by GC or the system or is there any way to prevent it? Thanks.

  • How to find header dependencies for large scale projects on linux

    - by user12371
    I'm working an a very large scale projects, where the compilation time is very long. What tools can I use (preferably open source) on Linux, to find the most heavily included files and that optimize their useages? Just to be clearer, I need a tool which will, given the dependencies, show me which headers are the most included. By the way, we do use distributed compiling

  • Useful Vim features

    - by Craig H
    Vim is my editor of choice, and I feel I am above average in my use of it. I do recognize, though, that the feature list of vim is huge. With this in mind, I was wondering what features you vim users out there use on a regular basis.

  • See queries that hit SQL

    - by Shaded
    I have a really basic stupid easy question about sql... and I'll probably get -100 points... but here it goes anyway... Is there a way using sql 2008 Management Studio to look at the queries that hit the server? I'm trying to debug a program and I get messages like "Incorrect syntax near the keyword 'AND'". Since the queries are being dynamically generated it's a hassle to figure out what is going to the server. Any help is appreciated!

  • How are builds deployed into QA->Staging->Production for ASP.NET Web Applications?

    - by CodeToGlory
    Secondary questions are How do we best utilize SCM in the build process? How are code files labed and branched? Should we the .csproj and .sln files for build? How flexible are these when deploying to several environments? I know these are msbuild files. But as we add new files, this can become a bottlenect of updating and maintaining these .csproj files in SCM. How is rollback done in case of failed builds that QA missed testing etc,etc., Are there any good articles on the build process? This is more a question on the process and less on the choice of automated build tools. Please share your build process. I would like to get an end-to-end view from developers checking-in to Going Live.

  • Should I split this model and table?

    - by regedarek
    I would like to create simple ResumeBank app. Issue: As user I would like to add only two Resumes. Forms for this both Resumes are different with only two fields. Resumes have 12 the same attributes but 2 are diferent. Question: Should I split that Resume model and tables to ex: PolishResume and EnglishResume, polish_remsumes and english_remsumes? Or maybe should I use STI and create PolishResume < Resume and use one table. What are disadvantages of splitting option?

  • What VNC (or similar) software for Windows 7 Home allows me to control my parents’ computer remotely as an administrator user?

    - by Paul D. Waite
    Here’s what I dream of: I install Windows 7 Home on my parents’ PC. They have a regular user account that they use, meaning they can’t install anything. I have an administrator account, meaning I can install things for them. I install some sort of VNC software on their machine that lets me access their computer remotely under the administrator account, so that I can install software for them (or do other administrator tasks, e.g. updates) without actually going to their house. Is there any VNC or VNC-like software that supports the above? (I guess I might be better off buying them Windows 7 Professional, and using Remote Desktop. At some point I’ll give up and get them an iPad, but for now, remote Windows admin is the dream.)

  • What software supports full multisession CD burning on windows?

    - by dma_k
    I know, that beating Nero in this field is very difficult. I have looked through best software listed in wiki, also checked the related posts here and here: most of the software either allows you to create ISO image and/or burn the existing image. However I am interested in the following flow: Import previous session Add/rename/remove files and directories Burn new session UltraISO is very good in (1) and (2). But it cannot append a disk with new session. InfraRecorder/CDBurnerXP can do (1) (2) (3) but: InfraRecorder crashes when trying to import some Nero sessions CDBurnerXP does not allow to move files in previous session to another directories. Is anybody here happy with any other free software?

  • Which software raid modes does each version of Windows 7 support?

    - by Goyuix
    Being familiar with the software raid modes and dynamic disks from the server versions, I was wondering if there is a document or even just common crowd knowledge that indicated what software raid support was available for each version of Windows 7. Also - all the various raid levels supported for booting or just a data recovery mechanism (e.g. you can connect three RAID-5 dynamic disks to an already booted system). I would prefer to stay away from modified/copied DLL's from the server variants, as well - please note - this is Windows software RAID - not fake-raid from your BIOS or an add-on card.

  • Automation of software installation - should I ask for text or file?

    - by Denis
    I am preparing a software installation in Windows environment for my application. During installation it asks for Subscriber ID which should be entered into text field. I am wondering if it is a best solution for mass installations. I know that for mass installations IT teams use systems like Microsoft System Center which allow automate deployment. But I do not know much about capabilities of such systems. Can such system automate data entry into the text fields? Will it be better to change installation process and ask not a text but a file which contains Subscriber ID? By the way, I am looking for beta testers for my software. This software let user view Microsoft Project files without having Microsoft Project installed.

  • Debian Wheezy: installing from sources or repositories? upgrading to new software release?

    - by user269842
    a. I'm wondering for some software if it is wiser to install them from sources or from official repositories when available like: glpi inventory fusion inventory monitoring tools like nagios I tried both for glpi: compiled from sources and installing from repositories. I also installed zabbix from sources. b. What about new software releases providing enhancements: is it better to keep the release installed from the repositories /compiled or is their a 'best practice' like downloading the new software release and compiling it again (I really have no clue)? Could someone make it more clear for me? Thanks!

  • Documenting software-updates semi-automatically in MacOS X by parsing log files?

    - by Martin
    I'd like to document changes I made to my computer (running MacOS 10.6.8) to be able to identify the sources of eventual problems. Mostly I install updates when a software notifies me about a newer version and offers me a dialog to download and install the update. Currently I'm documenting those updates "by hand" by noting in a text file, when I have e. g. installed a Flash-Player update or updated another 3rd party software ... I wonder if I could achieve that easier and semi-automatically by parsing system logfiles for certain texts like "install" and that way directly get the relevant information: what has been installed (Software and version) when has been installed where has it been installed/what has changed Is there a way to extract such information by a script from the existing logfiles?

  • Are Oracle Database CPU license limits enforced by software, and how do I check them?

    - by DrStalker
    I've inherited a windows VM running Oracle Database 10g. Currently the VM has only one CPU assigned to it, but I can boost this up to 4 with our VMWare licenses. What I'm not yet certain about is if the Oracle Software will get upset. Are Oracle DB CPU limits enforced by software, and if so how do I find out what they? If it's just a legal enforcement I'll hunt through the mass of unsorted paperwork I have left from previous managers to find what we're licensed for, but a quick software check would be nice.

  • SCCM - How to make new deployed applications appear in Software Center faster?

    - by icehac
    I am trying to make the process between SCCM deployments and the Software Center (configmgr) faster, if not seamless. Right now, applications generally take about 1-2 hours to populate properly. However, by going to the "Configuration Manager" under the Windows Control Panel, there is an "Actions" tab. Generally 5 minutes after running these "Actions", the software will populate inside the Software Center. The downside of this is the user interaction with the "Actions" pane...I can't have a user going through this process when they request a new application that needs to be deployed through SCCM. I have have played around with using "net stop ccmexec" and "net start ccmexec" to manually run all of these "Actions" on the start command, but it feels a bit archaic. Does anyone have any suggestions how to speed this process up? I feel there is something simple I am missing.

  • BI and EPM Landscape

    - by frank.buytendijk
    Most of my blog entries are not about Oracle products, and most of the latest entries are about topics such as IT strategy and enterprise architecture. However, given my background at Gartner, and at Hyperion, I still keep a close eye on what's happening in BI and EPM. One important reason is that I believe there is significant competitive value for organizations getting BI and EPM right. Davenport and Harris wrote a great book called "Competing on Analytics", in which they explain this in a very engaging and convincing way. At Oracle we have defined the concept of "management excellence" that outlines what organizations have to do to keep or create a competitive edge. It's not only in the business processes, but also in the management processes. Recently, Gartner published its 2009 market shares report for BI, Analytics, and Performance Management. Gartner identifies the same three segments that Oracle does: (1) CPM Suites (Oracle refers not to Corporate Performance Management, but Enterprise Performance Management), (2) BI Platform, and (3) Analytic Applications & Performance Management. According to Gartner, Oracle's share is increasing with revenue growing by more than 5%. Oracle currently holds the #2 market share position in the overall BI Software space based on total BI software revenue. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 Gartner has ranked Oracle as #1 in the CPM Suites worldwide sub-segment based on total BI software revenue, and Oracle is gaining share with revenue growing by more than 6% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 The Analytic Applications & Performance Management subsegment is more fragmented. It has for instance a very large "Other Vendors" category. The largest player traditionally is SAS. Analytic Applications are often meant for very specific analytic needs in very specific industry sectors. According to Gartner, from the large vendors, again Oracle is the one who is gaining the most share - with total BI software revenue growth close to 15% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 I believe this shows Oracle's integration strategy is working. In fact, integration actually is the innovation. BI and EPM have been silo technology platforms and application suites way too long. Management and measuring performance should be very closely linked to strategy execution, which is the domain of other business application areas such as CRM, ERP, and Supply Chain. BI and EPM are not about "making better decisions" anymore, but are part of a tangible action framework. Furthermore, organizations are getting more serious about ecosystem thinking. They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them "upperware". Many are active in the BI and EPM space. Big players can offer a lot, but there are always many areas that are covered by specialty vendors. Oracle openly embraces those technologies within the ecosystem as well. Complete, open and integrated still accurately describes the Oracle product strategy. frank

  • How much am I worth hourly as a software/web developer? [closed]

    - by luckysmack
    I may be starting a new job very soon as a developer for both web and desktop software. The primary languages I will be using is ASP.NET with C# with some php for existing projects(I've already had one interview which went very well). The job deals primarily in advertising. But this is my first real job in the market, I have no degrees, but have some college time(~1yr). So I am primarily self taught. They are fully aware of my skill set and lack of degrees or certificates. I applied as an entry level developer. It will be a permanent and full time/hourly position, and not a per contract job. So since it my cherry job, im not really sure what to ask for. even though im self taught im pretty confident in my skills and know what im doing fairly well. I pick up on new concepts very well and find new things fairly easy to learn. Here is a very brief summary of my skills: PHP: ~2years C#/.NET: 2 months Python: Basics only. ~1 month OOP Familiarity: Great (1 year) MVC Familiarity: Great (1 year) PHP Frameworks used: CakePHP(6 months), Yii(3 months), Lithium(3 months) CMS Familiar with: Drupal(1.5 years), Wordpress(only basics) I also have ~2yrs experience in maintaining my own VPS server and the hassles all that entails (linux/debian) Pretty much all the above will be used at this job. Although I will be using C# a vast majority of the time. I only recently started learning it but am moving along fairly rapidly and its all going smooth as butter. So what have I built? I have one proprietary site built in drupal which is used an an order log for products, inventory, and their shipments. It is also able to process payments through paypal merchant services. I have worked on a handful of other small apps used here and there I'm not able to show but which worked fairly well (all in php using frameworks though). The business does fairly well and is far from a a typical corporate type environment. It is much closer to a small development studio. And it is based out of northern California. I don't know how/what more info I can give on them. I also want this to be able to be referenced by other people possibly so I am looking for general tips and ideas to get an answer as well. I had trouble finding a reasonable range on other websites which seemed to be either way to low, or showed what a veteran developer makes. I know this is a fairly subjective question, but it is difficult to get a reasonable answer or guesstimate anywhere else. Even if only a little bit help, its much appreciated. So as for the direct question, based on all this info (did I miss anything?), how much should I ask for hourly? How much am I worth as a software developer?

  • Career development as a Software Developer without becoming a manager.

    - by albertpascual
    I’m a developer, I like to write new exciting code everyday, my perfect day at work is a day that when I wake up, I know that I have to write some code that I haven’t done before or to use a new framework/language/platform that is unknown to me. The best days in the office is when a project is waiting for me to architect or write. In my 15 years in the development field, I had to in order to get a better salary to manage people, not just to lead developers, to actually manage people. Something that I found out when I get into a management position is that I’m not that good at managing people, and not afraid to say it. I do not enjoy that part of the job, the worse one, takes time away from what I really like. Leading developers and managing people are very different things. I do like teaching and leading developers in a project. Yet most people believe, and is true in most companies, the way to get a better salary is to be promoted to a manager position. In order to advance in your career you need to let go of the everyday writing code and become a supervisor or manager. This is the path for developers after they become senior developers. As you get older and your family grows, the only way to hit your salary requirements is to advance your career to become a manager and get that manager salary. That path is the common in most companies, the most intelligent companies out there, have learned that promoting good developers mean getting a crappy manager and losing a good resource. Now scratch everything I said, because as I previously stated, I don’t see myself going to the office everyday and just managing people until is time to go home. I like to spend hours working in some code to accomplish a task, learning new platforms and languages or patterns to existing languages. Being interrupted every 15 minutes by emails or people stopping by my office to resolve their problems, is not something I could enjoy. All the sudden riding my motorcycle to work one cold morning over the Redlands Canyon and listening to .NET Rocks podcast, Michael “Doc” Norton explaining how to take control of your development career without necessary going to the manager’s track. I know, I should not have headphones under my helmet when riding a motorcycle in California. His conversation with Carl Franklin and Richard Campbell was just confirming everything I have ever did with actually more details and assuring that there are other paths. His method was simple yet most of us, already do many of those steps, Mr. Michael “Doc” Norton believe that it pays off on the long run, that finally companies prefer to pay higher salaries to those developers, yet I would actually think that many companies do not see developers that way, this is not true for bigger companies. However I do believe the value of those developers increase and most of the time, changing companies could increase their salary instead of staying in the same one. In short without even trying to get into the shadow of Mr. Norton and without following the steps in the order; you should love to learn new technologies, and then teach them to other geeks. I personally have learn many technologies and I haven’t stop doing that, I am a professor at UCR where I teach ASP.NET and Silverlight. Mr Norton continues that after than, you want to be involve in the development community, user groups, online forums, open source projects. I personally talk to user groups, I’m very active in forums asking and answering questions as well as for those I got awarded the Microsoft MVP for ASP.NET. After you accomplish all those, you should also expose yourself for what you know and what you do not know, learning a new language will make you humble again as well as extremely happy. There is no better feeling that learning a new language or pattern in your daily job. If you love your job everyday and what you do, I really recommend you to follow Michael’s presentation that he kindly share it on the link below. His confirmation is a refreshing, knowing that my future is not behind a desk where the computer screen is on my right hand side instead of in front of me. Where I don’t have to spent the days filling up performance forms for people and the new platforms that I haven’t been using yet are just at my fingertips. Presentation here. http://www.slideshare.net/LeanDog/take-control-of-your-development-career-michael-doc-norton?from=share_email_logout3 Take Control of Your Development Career Welcome!

He is giving us hope in the future of developers, when I see some of my geek friends moving to position that in short years they begin to regret, I get more unsure of my future doing what I love. I would say that now is looking at the spectrum of companies that understand and appreciate developers. There are a few there, hopefully with time code sweat shops will start disappearing and being a developer will feed a family of 4.

  • How to manage memory using classes in Objective-C?

    - by Flipper
    This is my first time creating an iPhone App and I am having difficulty with the memory management because I have never had to deal with it before. I have a UITableViewController and it all works fine until I try to scroll down in the simulator. It crashes saying that it cannot allocate that much memory. I have narrowed it down to where the crash is occurring: - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // Dequeue or create a cell UITableViewCellStyle style = UITableViewCellStyleDefault; UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:@"BaseCell"]; if (!cell) cell = [[[UITableViewCell alloc] initWithStyle:style reuseIdentifier:@"BaseCell"] autorelease]; NSString* crayon; // Retrieve the crayon and its color if (aTableView == self.tableView) { crayon = [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row] getName]; } else { crayon = [FILTEREDKEYS objectAtIndex:indexPath.row]; } cell.textLabel.text = crayon; if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor]; return cell; } Here is the getName method: - (NSString*)getName { return name; } name is defined as: @property (nonatomic, retain) NSString *name; Now sectionArray is an NSMutableArray with instances of a class that I created Term in it. Term has a method getName that returns a NSString*. The problem seems to be the part of where crayon is being set and getName is being called. I have tried adding autorelease, release, and other stuff like that but that just causes the entire app to crash before even launching. Also if I do: cell.textLabel.text = @"test"; //crayon; /*if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor];*/ Then I get no error whatsoever and it all scrolls just fine. Thanks in advance for the help! Edit: Here is the full Log of when I try to run the app and the error it gives when it crashes: [Session started at 2010-12-29 04:23:38 -0500.] [Session started at 2010-12-29 04:23:44 -0500.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • How a student programmer improve his teamwork skill?

    - by Turtle
    I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!
