  • How much code should I be responsible for?

    - by Mick
    Through colleagues and exit interviews, I have heard that at my small company I am "responsible" for anywhere from 3-10 times more code than I would be at another job. I'm trying to look for some sort of fuzzy metric that I can use to compare my workload with others in my field. By "code responsibility", I don't mean "I'm the only one who knows area X of the code base" (though sadly, it's often true in a startup environment), but rather am referring to a number like "code_base_size/number_of_developers". Are there any resources I can use to help me more accurately measure my work load than just counting lines of code?

  • designing classes with similar goal but widely different decisional core

    - by Stefano Borini
    I am puzzled on how to model this situation. Suppose you have an algorithm operating in a loop. At every loop, a procedure P must take place, whose role is to modify an input data I into an output data O, such that O = P(I). In reality, there are different flavors of P, say P1, P2, P3 and so on. The choice of which P to run is user dependent, but all P have the same finality, produce O from I. This called well for a base class PBase with a method PBase::apply, with specific reimplementations of P1::apply(I), P2::apply(I), and P3::apply(I). The actual P class gets instantiated in a factory method, and the loop stays simple. Now, I have a case of P4 which follows the same principle, but this time needs additional data from the loop (such as the current iteration, and the average value of O during the previous iterations). How would you redesign for this case?

  • EJB Lifecycle and Relation to WARs

    - by Adam Tannon
    I've been reading up on EJBs (3.x) and believe I understand the basics. This question is a "call for confirmation" that I have interpreted the Java EE docs correctly and that I understand these fundamental concepts: An EJB is to an App Container as a Web App (WAR) is to a Web Container Just like you deploy a WAR to a Web Container, and that container manages your WAR's life cycle, you deploy an EJB to an App Container, and the container manages your EJB's life cycle When the App Container fires up and deploys an EJB, it is given a unique "identifier" and URL that can be used by JNDI to look up the EJB from another tier (like the web tier) So, when your web app wants to invoke one of your EJB's methods, it looks the EJB up using some kind of service locator (JNDI) and invoke the method that way Am I on-track or way off-base here? Please correct me & clarify for me if any of these are incorrect. Thanks in advance!

  • How are crossplatform/multiple-OS C++ projects planned in terms of code and tools?

    - by Nav
    I want to create a project in C++ that can work in Windows, Linux and Embedded Linux. How are projects created when they have to work across many OS'es? Is it first created on one OS and then the code slowly modified to be ported to another OS? Eg: to me, the Linux version of Firefox appears to be created as a Windows project and a separate Linux project with a different code base, since Firefox behaves a bit different in Windows and Linux. Although the source code download is surprisingly a single link. If QT is used for UI, Boost threads for threading, Build Bot for CI and NetBeans/Eclipse/QT Creator for an IDE, would a person be able to minimise the amount of code re-write required to get the project onto another OS? Is this the right way to do it, or are such projects meant to be created as two entirely separate projects for two separate OS'es?

  • How to fix the copy/paste-pattern?

    - by Lenny222
    Where i work, people (consultants) feel pressed to release features as fast as possible. So instead of spending too much time on thinking about how to do things the right way or because they don't want to break anything, code gets copied from different modules and modified. It's not easy to prevent this, since the code base is open to the whole company. Lots of people work on this. Now that the mess is there already, what is the best way to remove those redundancies without breaking too much?

  • Stuxnet aurait préalablement été testé par les militaires d'Israël, plus de deux ans avant son lancement sur l'Iran

    Stuxnet aurait préalablement été testé par les militaires d'Israël, plus de deux ans avant son lancement sur l'Iran Mise à jour du 17.01.2011 par Katleen De nouvelles informations viennent de tomber concernant Stuxnet, la bête noire de l'Iran. Le ver aurait ainsi été testé en secret dans une base militaire Israélienne (le complexe Dimona dans le désert de Negev) avant d'être lâché sur les infrastructure nucléaires iraniennes. Deux ans avant leur mise en oeuvre, les attaques auraient été simulées sur les mêmes machines que celles visées, pour garantir le succès futur de l'opération grandeur nature. En conséquence, des experts auraient examiné les failles des contrôleurs ...

  • How do I draw video frames onto the screen permanently using XNA?

    - by izb
    I have an app that plays back a video and draws the video onto the screen at a moving position. When I run the app, the video moves around the screen as it plays. Here is my Draw method... protected override void Draw(GameTime gameTime) { Texture2D videoTexture = null; if (player.State != MediaState.Stopped) videoTexture = player.GetTexture(); if (videoTexture != null) { spriteBatch.Begin(); spriteBatch.Draw( videoTexture, new Rectangle(x++, 0, 400, 300), /* Where X is a class member */ Color.White); spriteBatch.End(); } base.Draw(gameTime); } The video moves horizontally acros the screen. This is not exactly as I expected since I have no lines of code that clear the screen. My question is why does it not leave a trail behind? Also, how would I make it leave a trail behind?

  • Estimated budget for RockBand 3 character creator feature [closed]

    - by milesmeow
    I want to get an idea of the budget required to make something akin to the Rock Band 3 character creator. We won't have the same level of detail for creating the base character, i.e. no face feature customization. We essentially want some very basic body sizing and want a bunch of clothing and accessories that the characters can try on. The clothing and accessories need to adapt and fit to the body types/shapes. The character should also support movement...and the clothes should move with the body. I've asked a similar question here regarding the development effort but not necessarily a budget. Do you think it's a $1M job? Most of the effort will go into creating the character models and the clothing models. The rest of the effort will go towards the user interface to navigate the customization features.

  • How to completely remove wicd from 12.04?

    - by danijelc
    I had issues with WiFi so I removed Network Manager. I booted Windows OS (dual booting Windows 7 and 12.04) to download wicd 1.7.2.4. Extracted it and installed. However, wcid worked properly with Wired Connection but could not connect to WiFi. So, I re-installed Network Manager which works properly now, and wicd connects to WiFi too. As soon as I disconnect from Network Manager, wicd connects only to wired. At this point, I wanted to remove wicd but apt-get returns no wicd installed, can't see it in Synaptic or Software Center, but only in Applications list under Dash home. Of course wcid icon shows connections, and resulting connected, so my system shows both applets for wicd and network manager in the top panel. When running dpkg commands, wicd is not listed as installed package. Any suggestion how to remove wicd? Consider that I started with Ubuntu just few months ago so my knowledge base is limited.

  • SEO and Spelling mistakes in keyword

    - by Sushil
    I am about to register a domain name (suppose) someone.com (with proper spelling), in mind targeting the keyword "SOMEONE". But then I discovered on 'google keyword research tool' that not this but a typo "SOME1" seems to be more popular and people search this significantly more often than the proper keyword. And luckily someone.com and some1.com both are available. I understand that I can register both the domains, but I don't know on which should I keep my website and redirect the other one. Should I make the typo "some1.com" my base site? But that's a typo. P.S., my site has a totally relevant content and not just keyword targeted worthless site. What do you guys suggest? I am confused. How would that affect my SEO ranking?? EDIT: Because the competition for the keyword I am targeting is fairly low, I think nevertheless whatever domain I choose, it will appear on the search engine first page.

  • Which tools helps to start Ubuntu GUI when boot?

    - by Vimal Kumar
    I am on the way to create a Live CD from scratch. I used Virtual Box for this purpose. I installed Ubuntu base from ubuntumini.iso and installed gnome-shell. And installed Remastersys and created a backup.iso. Burned in a CD and boot from a PC. It end in CLI. Not lead to GUI. I tried the same ISO in VirtualBox. But it work properly there. I think I missed some packages which help to start GUI. Can you help me to identify the packages missed to include in the CD?

  • 7 Steps To Cut Recruiting Costs & Drive Exceptional Business Results

    - by Oracle Accelerate for Midsize Companies
    By Steve Viarengo, Vice President Product Management, Oracle Taleo Cloud Services  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 In good times, trimming operational costs is an ongoing goal. In tough times, it’s a necessity. In both good times and bad, however, recruiting occurs. Growth increases headcount in good times, and opportunistic or replacement hiring occurs in slow business cycles. By employing creative recruiting strategies in tandem with the latest technology developments, you can reduce recruiting costs while driving exceptional business results. Here are some critical areas to focus on. 1.  Target Direct Cost Savings Total recruiting process expenses are the sum of external costs plus internal labor costs. Most organizations can reduce recruiting expenses with direct cost savings. While additional savings on indirect costs can be realized from process improvement and efficiency gains, there are direct cost savings and benefits readily available in three broad areas: sourcing, assessments, and green recruiting. 2. Sourcing: Reduce Agency Costs Agency search firm fees can amount to 35 percent of a new employee’s annual base salary. Typically taken from the hiring department budget, these fees may not be visible to HR. By relying on internal mobility programs, referrals, candidate pipelines, and corporate career Websites, organizations can reduce or eliminate this agency spend. And when you do have to pay third-party agency fees, you can optimize the value you receive by collaborating with agencies to identify referred candidates, ensure access to candidate data and history, and receive automatic notifications and correspondence. 3. Sourcing: Reduce Advertising Costs You can realize significant cost reductions by placing all job positions on your corporate career Website. This will allow you to reap a substantial number of candidates at minimal cost compared to job boards and other sourcing options. 4.  Sourcing: Internal Talent Pool Internal talent pools provide a way to reduce sourcing and advertising costs while delivering improved productivity and retention. Internal redeployment reduces costs and ramp-up time while increasing retention and employee satisfaction. 5.  Sourcing: External Talent Pool Strategic recruiting requires identifying and matching people with a given set of skills to a particular job while efficiently allocating sourcing expenditures. By using an e-recruiting system (which drives external talent pool management) with a candidate relationship database, you can automate prescreening and candidate matching while communicating with targeted candidates. Candidate relationship management can lower sourcing costs by marketing new job opportunities to candidates sourced in the past. By mining the talent pool in this fashion, you eliminate the need to source a new pool of candidates for each new requisition. Managing and mining the corporate candidate database can reduce the sourcing cost per candidate by as much as 50 percent. 6.  Assessments: Reduce Turnover Costs By taking advantage of assessments during the recruitment process, you can achieve a range of benefits, including better productivity, superior candidate performance, and lower turnover (providing considerable savings). Assessments also save recruiter and hiring manager time by focusing on a short list of qualified candidates. Hired for fit, such candidates tend to stay with the organization and produce quality work—ultimately driving revenue.  7. Green Recruiting: Reduce Paper and Processing Costs You can reduce recruiting costs by automating the process—and making it green. A paperless process informs candidates that you’re dedicated to green recruiting. It also leads to direct cost savings. E-recruiting reduces energy use and pollution associated with manufacturing, transporting, and recycling paper products. And process automation saves energy in mailing, storage, handling, filing, and reporting tasks. Direct cost savings come from reduced paperwork related to résumés, advertising, and onboarding. Improving the recruiting process through sourcing, assessments, and green recruiting not only saves costs. It also positions the company to improve the talent base during the recession while retaining the ability to grow appropriately in recovery. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";} Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

  • Code Smell: Inheritance Abuse

    - by dsimcha
    It's been generally accepted in the OO community that one should "favor composition over inheritance". On the other hand, inheritance does provide both polymorphism and a straightforward, terse way of delegating everything to a base class unless explicitly overridden and is therefore extremely convenient and useful. Delegation can often (though not always) be verbose and brittle. The most obvious and IMHO surest sign of inheritance abuse is violation of the Liskov Substitution Principle. What are some other signs that inheritance is The Wrong Tool for the Job even if it seems convenient?

  • 0.00006103515625 GB of RAM. Is .NET MicroFramework part of Windows CE?

    - by Rocket Surgeon
    The .NET MicroFramework claims to work on 64K RAM and has list of compatible targets vendors. At the same time, same vendors who ship hardware and create Board Support Packages (vendors like Adeneo) keep releasing something named Windows 7 CE BSP for the same hardware targets. Obviously the OS as heavy as WinCE needs more than 64K RAM. So, somehow .NET MicroFramework is relevant to WinCE, but how ? Is it part of bigger OS or is it base of it, or are both mutually exclusive ? Background: 0.00006103515625 GByte of RAM is same as 64Kbyte of RAM. I am looking for possiblity to use Microsoft development tools for small target like BeagleBone. http://www.adeneo-embedded.com/About-Us/News/Release-of-TI-BeagleBone Nice. Now .. where is a MicroFramework for the same beaglebone ? Is it inside the released pile ?

  • Forking project on Github etiquette

    - by Mike Wills
    There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

  • What the best way to wire up Entity Framework database context (model) to ViewModel in MVVM WPF?

    - by hal9k2
    As in the question above: What the best way to wire up Entity Framework database model (context) to viewModel in MVVM (WPF)? I am learning MVVM pattern in WPF, alot of examples shows how to implement model to viewModel, but models in that examples are just simple classes, I want to use MVVM together with entity framework model (base first approach). Whats the best way to wire model to viewModel. Thanks for answers. //ctor of ViewModel public ViewModel() { db = new PackageShipmentDBEntities(); // Entity Framework generated class ListaZBazy = new ObservableCollection<Pack>(db.Packs.Where(w => w.IsSent == false)); } This is my usual ctor of ViewModel, think there is a better way, I was reading about repository pattern, not sure if I can adapt this to WPF MVVM

  • How to document experimental or incomplete APIs like @deprecated?

    - by Michael Levy
    Is there a good term that is similar but different than "deprecate" to mean that a method or API is in the code base but should not be used because its implementation is not complete or will likely change? (Yeah, I know, those methods shouldn't be public, yada yada yada. I didn't create my situation, I'm just trying to make the best of it.) What do people suggest? Experimental, Incomplete, something else? If I'm building javadoc documentation for this API that is still in flux, should I use the @deprecated tag or is there a better convention? To me @deprecated implies that this API is old and a newer preferred mechanism is available. In my situation, there is no alternative, but some of the methods in the API are not finished and so should not be used. At this point I cannot make them private, but I'd like to put clear warnings in the docs.

  • Strategy/algorithm to divide fair teams based on history

    - by Vegar
    We are a group of people playing floorball together on a regular basis. Every session starts with the daunting task of dividing teams... So what would be better than an application to pick teams automatically? So, given a history of team-combinations and results, and a list of people showing up for this particular session, what would be a good strategy to find the optimal teams? By optimal, I mean teams as equal as possible. Any ideas? Edit: To make it clear, the date that I have to base the picking on, would be something like this: [{ team1: ["playerA", "playerB", "playerC"], team2: ["playerD", "playerE", "playerF"], goals_team1: 10, goals_team2: 8 }, { team1: ["playerD", "playerB", "playerC"], team2: ["playerA", "playerE", "playerG"], goals_team1: 2, goals_team2: 5 }, { team1: ["playerD", "playerB", "playerF"], team2: ["playerA", "playerE", "playerC"], goals_team1: 4, goals_team2: 2 }]

  • How should I account for the GC when building games with Unity?

    - by Eonil
    *As far as I know, Unity3D for iOS is based on the Mono runtime and Mono has only generational mark & sweep GC. This GC system can't avoid GC time which stops game system. Instance pooling can reduce this but not completely, because we can't control instantiation happens in the CLR's base class library. Those hidden small and frequent instances will raise un-deterministic GC time eventually. Forcing complete GC periodically will degrade performance greatly (can Mono force complete GC, actually?) So, how can I avoid this GC time when using Unity3D without huge performance degrade?

  • How important is to sacrifice your free time for accomplishing goals? [closed]

    - by Darf Zon
    I was reading a book about XP programming and about agile teams. While I was reading, I saw this scenario. I've never worked with a development team (just in school). So I would like what do you opine on this situation: Your boss has asked you to deliver software in a time that can only be possible to meet the project team asking if you want to work overtime without pay. All team members have young children. Discuss whether it should accept this request from your boss or should persuade the team to give their time to the organization rather than their families. What could be significant factors in the decision? As a programmer, you are offered an upgrade as project manager, but his feeling is that you can have a more effective contribution in a technical role in one administrative. Write when you should accept that promotion. Somethimes, I sacrifice my free time for accomplishing hits at work, so it's very important to me to know your opinion base of your experience.
