  • Multilingual website without language component in the URL

    - by user359650
    I'm working on a website for Canada which will have French and English versions. For SEO purposes, I would like to avoid using any language tag in URLs because I believe it will have more impact (e.g. example.ca/products better than en.example.ca/products or example.ca/en/products). I believe this is technically possible because the2 languages are sufficiently different that the URLs won't be conflicting with one another (e.g. if you want a "product" page, it will be /products in English, and /produits in French so you know which language the URL is about). Since Google (and most likely others) doesn't rely on the URL (nor HTML tags) to determine the content language I don't see any problems with search engines. To make this possible I've thought about using a cookie distinct from the session cookie (e.g. example.org_language) with long term expiry (e.g. N years) that will memorize the language chosen by the user. That way when people visit the website with a new browser session, they get served the proper language. I have already given up on users being able to switch one page from English to French: when people will chose English or French from the menu they will be redirected to the corresponding version of the home page. Do you foresee any problems with not using a language component in the URL (whether domain or path)? (as long as one makes sure URLS don't conflict).

  • Compiling GCC or Clang for thumb drive on OSX

    - by user105524
    I have a mac book that I don't have admin rights to which I would like to be able to use either GCC or clang. Since I lack admin right I can't install binutils or a compiler to /usr directory. My plan is to install both of these (using an old macbook that I do have admin rights for) to a flash drive and then run the compiler off of there. How would one go building gcc or clang so that it could run just off of a thumb drive? I've tried both but haven't had any success. I've tried doing it defining as many of the directories as possible through configure, but haven't been able to successfully build. My current configure script for gcc-4.8.1 is (where USB20D is the thumb drive): ../gcc-4.8.1/configure --prefix=/Volumes/USB20FD/usr \ --with-local-prefix=/Volumes/USB20FD/usr/local \ --with-native-system-header-dir=/Volumes/USB20FD/usr/include \ --with-as=/Volumes/USB20FD/usr/bin/as \ --enable-languages=c,c++,fortran\ --with-ld=/Volumes/USB20FD/usr/bin/ld \ --with-build-time-tools=/Volumes/USB20FD/usr/bin \ AR=/Volumes/USB20FD/usr/bin/ar \ AS=/Volumes/USB20FD/usr/bin/as \ RANLIB=/Volumes/USB20FD/usr/bin/ranlib \ LD=/Volumes/USB20FD/usr/bin/ld \ NM=/Volumes/USB20FD/usr/bin/nm \ LIPO=/Volumes/USB20FD/usr/bin/lipo \ AR_FOR_TARGET=/Volumes/USB20FD/usr/bin/ar \ AS_FOR_TARGET=/Volumes/USB20FD/usr/bin/as \ RANLIB_FOR_TARGET=/Volumes/USB20FD/usr/bin/ranlib \ LD_FOR_TARGET=/Volumes/USB20FD/usr/bin/ld \ NM_FOR_TARGET=/Volumes/USB20FD/usr/bin/nm \ LIPO_FOR_TARGET=/Volumes/USB20FD/usr/bin/lipo CFLAGS=" -nodefaultlibs -nostdlib -B/Volumes/USB20FD/bin -isystem/Volumes/USB20FD/usr/include -static-libgcc -v -L/Volumes/USB20FD/usr/lib " \ LDFLAGS=" -Z -lc -nodefaultlibs -nostdlib -L/Volumes/USB20FD/usr/lib -lgcc -syslibroot /Volumes/USB20FD/usr/lib/crt1.10.6.o " Any obvious ideas of which of these options need to be turned on to install the appropriate files on the thumb drive during installation? What other magic occurs during xcode installation which isn't occurring here? Thanks for any suggestions

  • How to organize a larger project with several sub-projects and their dependencies?

    - by RoToRa
    As a software developer until now, I've mostly worked on projects that were quite "monolithic" with hardly any dependencies on other projects, without building automation (no Make, Ant, Maven, etc.) and kept on a simple version control system (mostly Subversion) with just a few easily managed version branches. Now together with some friends I'm planning a project that is intended to run on multiple platforms (mostly mobile: Android, iOS, Kindle, Windows, etc.), thus written in several languages and on different development platforms. This will lead to many dependencies: All projects sharing the same resources (e.g. images) or projects dependent on each other (e.g. a core Java library project used by the Android and other Java based implementations). So what I need is some basic information on how to answer questions such as: How would the VCS be structured? Would a client-base or a decentralized VCS be better? How to decide building automation system(s) to use? Since this quite an open question I guess for now it would be great if you could point me to any books or web resources that you can recommend for this topic.

  • Why are embedded device apps still written in C/C++? Why not Java programming language?

    - by hinkmond
    At the recent Black Hat 2014 conference in Sin City, the Black Hatters were focusing on Embedded Devices and IoT. You know? Make your networked-toaster burn your bread 10,000 miles away, over the Web for grins and giggles. Well, apparently the Black Hatters say it can be done pretty easily these days, which is scary. See: Securing Embedded Devices & IoT Here's a quote: All these devices are still written in C and C++. The challenges associated with developing securely in these languages have been fought for nearly two decades. "You often hear people say, 'Well, why don't we just get rid of the C and C++ language if it's so problematic. Why don't we just write everything in C# or Java, or something that is a little safer to develop in?'," DeMott says. Gah! Why are all these IoT devices still using C/C++? Of course they should be using Java SE Embedded technology! It's a natural fit to use for better security on embedded devices. Or, I guess, developers really don't mind if their networked-toasters do char their breakfast. If it can be burned, it will be... That's what I say. Unless they use Java. Hinkmond

  • How to recover broken dpkg after lucid-bleed ppa-purge?

    - by TryTryAgain
    Did a ppa-purge of lucid-bleed and dpkg didn't downgrade properly and now it is broken. dpkg: PreDepends: tar (>= 1.23) but 1.22-2ubuntu1 is to be installed What scares me is when simulating the removal of dpkg I get: Removing this package may render the system unusable. Are you sure you want to do that? and then the list of packages which depend on it, which will also be removed, is obviously very long. Is it safe for me to remove dpkg just to reinstall it? How would I ensure the list of packages which were also removed are then reinstalled? Will forcing the version of dpkg help? (FYI: simulating a forced version brings up a much smaller list of applications which will also be removed). Any other suggestions? Additional information based on comments: ppa-purge log: http://pastebin.com/1kT8cLvP If I sudo apt-get install dpkg=1.15.5.6ubuntu4.5 I get The following packages have unmet dependencies: libdpkg-perl: Depends: dpkg (= 1.15.8) but 1.15.5.6ubuntu4.5 is to be installed which sucks because that means more would be broken after doing so...but when I force the version through Synaptic I get: To be removed alien, build-essential, cdbs, checkinstall, debhelper, devscripts, dpkg-dev, google-earth-stable, googleearth-package, libdpkg-perl, lintian, lsb, lsb-core, lsb-cxx, lsb-desktop, lsb-graphics, lsb-languages, lsb-multimedia, lsb-printing, lsb-qt4, lsb-security, ubuntu-dev-tools.

  • What's the proper term for a function inverse to a constructor? Deconstructor, destructor, or something else?

    - by Petr Pudlák
    Edit: I'm rephrasing the question a bit. Apparently I caused some confusion because I didn't realize that the term destructor is used in OOP for something quite different - it's a function invoked when an object is being destroyed. In functional programming we (try to) avoid mutable state so there is no such equivalent to it. (I added the proper tag to the question.) Instead, I've seen that the record field for unwrapping a value (especially for single-valued data types such as newtypes) is sometimes called destructor or perhaps deconstructor. For example, let's have (in Haskell): newtype Wrap = Wrap { unwrap :: Int } Here Wrap is the constructor and unwrap is what? I've seen both, for example: ... Most often, one supplies smart constructors and destructors for these to ease working with them. ... at Haskell wiki, or ... The general theme here is to fuse constructor - deconstructor pairs like ... at Haskell wikibook (here it's probably meant in a bit more general sense). The questions are: How do we call unwrap in functional programming? Deconstructor? Destructor? Or by some other term? And to clarify, is this terminology applicable to other functional languages, or is it used just in the Has

  • Code base migration - old versioning system to modern

    - by JohnP
    Our current code base is contained in a versioning system that is old and outdated (Visual Sourcesafe 5.0, mid 1990's), and contains a mix of packages that are no longer used, ones that are being used but no longer updated, and newer code. It is also a mix of 4 languages, and includes libraries for some of our systems (Such as Dialogic, Sun Tzu {clipper}) implementations. This breaks down into the following categories: Legacy code - No longer used (Systems that have been retired or replaced, etc) Legacy code - In current use (No intentions for upgrades or minor bug fixes, only major fixes if needed) Current code - In current use, and will be used for future versions/development Support libraries - For both legacy and current code (Some of the legacy libraries are no longer available as well) We would like to migrate this to a newer versioning system as we will be adding more developers, and expanding the reach to include remote programmers. When migrating, how do you structure it? Do you just perform a dump of all the data and then import it into the new system, or do you segregate according to type before you bring it into the new system? Do you set up a separate area for libraries, or keep them with the relevant packages? Do you separate by language, system, both? A general outline and methodology is fine, it doesn't need to be broken down to individual program level.

  • @CodeStock 2012 Review: Leon Gersing ( @Rubybuddha ) - "You"

    "YOU"Speaker: Leon GersingTwitter: @Rubybuddha Site: http://about.me/leongersing I honestly had no idea what I was getting in to when I sat down in to this session. I basically saw the picture of the speaker and knew that it would be a good session. I was completely wrong; it was the BEST SESSION of CodeStock 2012.  In fact it was so good, I texted another coworker attending the conference to get over and listen to Leon. Leon took on the concept of growth in the software development community. He specifically referred David Hansson in his ability to stick to his beliefs when the development community thought that he was crazy for creating Ruby on Rails. If you do not know this story Ruby on Rails is one of the fastest growing web languages today. In addition, he also touched on the flip side of this argument in that we must be open to others ideas and not discard them so quickly because we all come from differing perspectives and can add value to a project/team/community. This session left me with two very profound concepts/quotes: “In order to learn you must do it badly in front of a crowed and fail.” - @Rubybuddha I can look back on my career so far and say that he is correct; I think I have learned the most after failing, especially when I achieved this failure in front of other. “Experts must be able to fail.” - @Rubybuddha I think we can all learn from our own mistakes but we can also learn from others. When respected experts fail it is a great learning opportunity for the entire team as well as the person who failed. When expert admit mistakes and how they worked through them can be great learning tools for other developers so that they know how to avoid specific scenarios and if they do become stuck in the same issue they will know how to properly work their way out of them.

  • Building Enterprise Smartphone App &ndash; Part 4: Application Development Considerations

    - by Tim Murphy
    This is the final part in a series of posts based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Application Development Considerations Now we get to the actual building of your solutions.  What are the skills and resources that will be needed in order to develop a smartphone application in the enterprise? Language Knowledge One of the first things you need to consider when you are deciding which platform language do you either have the most in house skill base or can you easily acquire.  If you already have developers who know Java or C# you may want to use either Android or Windows Phone.  You should also take into consideration the market availability of developers.  If your key developer leaves how easy is it to find a knowledgeable replacement? A second consideration when it comes to programming languages is the qualities exposed by the languages of a particular platform.  How well does that development language and its associated frameworks support things like security and access to the features of the smartphone hardware?  This will play into your overall cost of ownership if you have to create this infrastructure on your own. Manage Limited Resources Everything is limited on a smartphone: battery, memory, processing power, network bandwidth.  When developing your applications you will have to keep your footprint as small as possible in every way.  This means not running unnecessary processes in the background that will drain the battery or pulling more data over the airwaves than you have to.  You also want to keep your on device in as compact a format as possible. Mobile Design Patterns There are a number of design patterns that have either come to life because of smartphone development or have been adapted for this use.  The main pattern in the Windows Phone environment is the MVVM (Model-View-View-Model).  This is great for overall application structure and separation of concerns.  The fun part is trying to keep that separation as pure as possible.  Many of the other patterns may or may not have strict definitions, but some that you need to be concerned with are push notification, asynchronous communication and offline data storage. Real estate is limited on smartphones and even tablets. You are also limited in the type of controls that can be represented in the UI. This means rethinking how you modularize your application. Typing is also much harder to do so you want to reduce this as much as possible.  This leads to UI patterns.  While not what we would traditionally think of as design patterns the guidance each platform has for UI design is critical to the success of your application.  If user find the application difficult navigate they will not use it. Development Process Because of the differences in development tools required, test devices and certification and deployment processes your teams will need to learn new way of working together.  This will include the need to integrate service contracts of back-end systems with mobile applications.  You will also want to make sure that you present consistency across different access points to corporate data.  Your web site may have more functionality than your smartphone application, but it should have a consistent core set of functionality.  This all requires greater communication between sub-teams of your developers. Testing Process Testing of smartphone apps has a lot more to do with what happens when you lose connectivity or if the user navigates away from your application. There are a lot more opportunities for the user or the device to perform disruptive acts.  This should be your main testing concentration aside from the main business requirements.  You will need to do things like setting the phone to airplane mode and seeing what the application does in order to weed out any gaps in your handling communication interruptions. Need For Outside Experts Since this is a development area that is new to most companies the need for experts is a lot greater. Whether these are consultants, vendor representatives or just development community forums you will need to establish expert contacts. Nothing is more dangerous for your project timelines than a lack of knowledge.  Make sure you know who to call to avoid lengthy delays in your project because of knowledge gaps. Security Security has to be a major concern for enterprise applications. You aren't dealing with just someone's game standings. You are dealing with a companies intellectual property and competitive advantage. As such you need to start by limiting access to the application itself.  Once the user is in the app you need to ensure that the data is secure at all times.  This includes both local storage and across the wire.  This means if a platform doesn’t natively support encryption for these functions you will need to find alternatives to secure your data.  You also need to keep secret (encryption) keys obfuscated or locked away outside of the application. People can disassemble the code otherwise and break your encryption. Offline Capabilities As we discussed earlier one your biggest concerns is not having connectivity.  Because of this a good portion of your code may be dedicated to handling loss of connection and reconnection situations.  What do you do if you lose the network?  Back up all your transactions and store of any supporting data so that operations can continue off line. In order to support this you will need to determine the available flat file or local data base capabilities of the platform.  Any failed transactions will need to support a retry mechanism whether it is automatic or user initiated.  This also includes your services since they will need to be able to roll back partially completed transactions.  What ever you do, don’t ignore this area when you are designing your system. Deployment Each platform has different deployment capabilities. Some are more suited to enterprise situations than others. Apple's approach is probably the most mature at the moment. Prior to the current generation of smartphone platforms it would have been Windows CE. Windows Phone 7 has the limitation that the app has to be distributed through the same network as public facing applications. You mark them as private which means that they are only accessible by a direct URL. Unfortunately this does not make them undiscoverable (although it is very difficult). This will change with Windows Phone 8 where companies will be able to certify their own applications and distribute them.  Given this Windows Phone applications need to be more diligent with application access in order to keep them restricted to the company's employees. My understanding of the Android deployment schemes is that it is much less standardized then either iOS or Windows Phone. Someone would have to confirm or deny that for me though since I have not yet put the time into researching this platform further. Given my limited exposure to the iOS and Android platforms I have not been able to confirm this, but there are varying degrees of user involvement to install and keep applications updated. At one extreme the user just goes to a website to do the install and in other case they may need to download files and perform steps to install them. Future Bluetooth Today we use Bluetooth for keyboards, mice and headsets.  In the future it could be used to interrogate car computers or manufacturing systems or possibly retail machines by service techs.  This would open smartphones to greater use as a almost a Star Trek Tricorder.  You would get you all your data as well as being able to use it as a universal remote for just about any device or machine. Better corporation controlled deployment At least in the Windows Phone world the upcoming release of Windows Phone 8 will include a private certification and deployment option that is currently not available with Windows Phone 7 (Mango). We currently have to run the apps through the Marketplace certification process and use a targeted distribution method. Platform independent approaches HTML5 and JavaScript with Web Service has become a popular topic lately for not only creating flexible web site, but also creating cross platform mobile applications.  I’m not yet convinced that this lowest common denominator approach is viable in most cases, but it does have it’s place and seems to be growing.  Be sure to keep an eye on it. Summary From my perspective enterprise smartphone applications can offer a great competitive advantage to many companies.  They are not cheap to build and should be approached cautiously.  Understand the factors I have outlined in this series, do you due diligence and see if there is a portion of your business that can benefit from the mobile experience. del.icio.us Tags: Architecture,Smartphones,Windows Phone,iOS,Android

  • Discovering Your Project

    - by Tim Murphy
    The discovery phase of any project is both exciting and critical to the project’s success.  There are several key points that you need to keep in mind as you navigate this process. The first thing you need to understand is who the players in the project are and what their motivations are for the project.  Leaving out a key stakeholder in the resulting product is one of the easiest ways to doom your project to fail.  The better the quality of the input you have at this early phase the better chance you will have of creating a well accepted deliverable. The next task you should tackle is to gather the goals for the project.  Specifically, what does the company expect to get for the money they are about to layout.  This seems like a common sense task, but you would be surprised how many teams to straight to building the system.  Even if you are following an agile methodology I believe that this is critical. Inventorying the resources that already exists gives you an idea what you are going to have to build and what you can leverage at lower risk.  This list should include documentation, servers, code repositories, databases, languages, security systems and supporting teams.  All of these are “resources” that can effect the cost and delivery schedule of your project. Finally, you need to verify what you have found and documented with the stakeholders and subject matter experts.  Documentation that has not been reviewed is actually a list of assumptions and we all know that assumptions are the mother of all screw ups. If you give the discovery phase of your project the attention that it deserves your project has a much better chance of success. I would love to hear what other people find important for this phase.  Please leave comments on this post so we can share the knowledge. del.icio.us Tags: Project discovery,documentation,business analysis,architecture

  • Writing a DB Python or Ruby

    - by WojonsTech
    I am planning on writing a database. I know it's crazy and people will tell me there is no good reason to do so. I am really using it to get better at programming overall, this database wont be used in production. I am planning on writing it Ruby or Python. I have some experience with both languages, but no job or large project experience. I don't want this to be a this is better than that randomly I really need some facts. The things that I need to know are which of the language are better at the following things. Searching arrays/hashes? Sorting? Threading? Sockets? Memory management? Disk Reads/Writes? base64 encode/decode? Again this is just a project for myself. I will port it on github for the hell of it, but I don't expect it to be amazing or going up against mysql or mongodb any day.

  • Composing programs from small simple pieces: OOP vs Functional Programming

    - by Jay Godse
    I started programming when imperative programming languages such as C were virtually the only game in town for paid gigs. I'm not a computer scientist by training so I was only exposed to Assembler and Pascal in school, and not Lisp or Prolog. Over the 1990s, Object-Oriented Programming (OOP) became more popular because one of the marketing memes for OOP was that complex programs could be composed of loosely coupled but well-defined, well-tested, cohesive, and reusable classes and objects. And in many cases that is quite true. Once I learned object-oriented programming my C programs became better because I structured them more like classes and objects. In the last few years (2008-2014) I have programmed in Ruby, an OOP language. However, Ruby has many functional programming (FP) features such as lambdas and procs, which enable a different style of programming using recursion, currying, lazy evaluation and the like. (Through ignorance I am at a loss to explain why these techniques are so great). Very recently, I have written code to use methods from the Ruby Enumerable library, such as map(), reduce(), and select(). Apparently this is a functional style of programming. I have found that using these methods significantly reduce code volume, and make my code easier to debug. Upon reading more about FP, one of the marketing claims made by advocates is that FP enables developers to compose programs out of small well-defined, well-tested, and reusable functions, which leads to less buggy code, and low code volume. QUESTIONS: Is the composition of complex program by using FP techniques contradictory to or complementary to composition of a complex program by using OOP techniques? In which situations is OOP more effective, and when is FP more effective? Is it possible to use both techniques in the same complex program? Do the techniques overlap or contradict each other?

  • I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

    - by Shin San
    I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

  • Need theoretical help, how to comprehend an if-else dependency net

    - by macbie
    I am going to face a following issue: I'm writing a program that manages some properties, some of them are general and some are specific. Each property is a pair of key and value, and for example: if it is given a general property and other specific property with exactly the same key and value has been existed before then the general property will swap the specific one in the register. If there are two the same general properties - both will remain in the register. And so on; it is like a net of dependencies. In my case I can handle with it intuitively and foresee all cases, but only because the system is not too vast. What if it would? I have met such problems a few times in many different programs and languages (i.e working with C semaphores) and my question is: How to approach this kind of problem? Is this connected with finite state machine, graph theory or something similar? How to be sure that I have considered the whole system and each possible case? Could you recommend some resources (books, sites) to learn from?

  • Where to Start?

    - by freemann098
    my name is Chase. I've been programming for over 3 years now and I've made very little progress towards game development. I blame myself for it due to reasons. I have experience in many languages such as C++, C#, and Java. I have a little bit of knowledge in JavaScript/HTML and Python. My question is where to start on actually understanding jumping into game development. Whenever I watch game development tutorials it mostly makes sense until points of things like OpenGL or advanced topics that make no sense at all. An example is something like glOrhho Matrix or whatever. Videos either don't explain things like this or they're not explained very well. Do I not know enough basics? I find myself always copying code from a video but understanding very little of it. It's like i'm memorizing things I don't understand which makes it hard to program at all. If I were to want to get to the point where I could write my own game engine or just a game by myself in general in C++ using at the most documentation how would I start at mastering to that level. Should I learn C first, or get really good at basics in general with C++. I know there is a similar posted question on this site but it's not the same due to the fact the person asking the question has a well knowledge level in programming. I'm stuck in a loop of learning the same things but if I go farther I don't understand. I'm stuck in the same spot and need to make progress.

  • Stuff you learned in school, that you have never used again?

    - by Mercfh
    Obviously we learn plenty of things in our University/College/Whatever that probably don't apply to everyday use, but is there anything that stands out particularly? Maybe something that was concentrated ALOT on? For me it was def. 2 things: OO Concepts and Pointers I still use OO, but not nearly to the amount people made it out to be, i can see where it'd be useful but in my line of work we don't have huge amounts of classes, maybe a couple at most. And there certainly isn't much OO reuse (i finally figured out what that means lol) Pointers are another thing, again I can see where they'd be useful...however I barely barely ever touch them, nor do the others I work with. I guess language choice has alot to do with that but still. What about you guys? edit: For those who are asking I work for a Large Printer company, and most of the Applications we work on are Java+XML and Actionscript for "Printer Apps". But we are moving towards other languages (think like webkits and stuff). So the Code amounts per parts are quite small. I never say OO wasn't useful I just said I personally havent seen it used in my workplace much.

  • Reaching Intermediate Programming Status

    - by George Stocker
    I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

  • Which is a better practice - helper methods as instance or static?

    - by Ilian Pinzon
    This question is subjective but I was just curious how most programmers approach this. The sample below is in pseudo-C# but this should apply to Java, C++, and other OOP languages as well. Anyway, when writing helper methods in my classes, I tend to declare them as static and just pass the fields if the helper method needs them. For example, given the code below, I prefer to use Method Call #2. class Foo { Bar _bar; public void DoSomethingWithBar() { // Method Call #1. DoSomethingWithBarImpl(); // Method Call #2. DoSomethingWithBarImpl(_bar); } private void DoSomethingWithBarImpl() { _bar.DoSomething(); } private static void DoSomethingWithBarImpl(Bar bar) { bar.DoSomething(); } } My reason for doing this is that it makes it clear (to my eyes at least) that the helper method has a possible side-effect on other objects - even without reading its implementation. I find that I can quickly grok methods that use this practice and thus help me in debugging things. Which do you prefer to do in your own code and what are your reasons for doing so?

  • Interview questions for programming tutor?

    - by Emmett Gear
    My family is looking for a programming/computer science tutor. Personally, I want to learn Java or some other brand of web programming. I am best described as a PC "power user." I have never programmed in the past and would like a good jump start. I am a very quick learner and do not expect the tutor to have to teach me the ultra basic stuff that I can learn myself. My son also needs a programming tutor. He just got into Carnegie Mellon as a computer science major. Having done only robotics and mathematics in the past he is very nervous that he does not have the same level of knowledge as his future classmates. I need some help coming up with a list of questions to ask potential tutors and some criteria to judge them by. Thanks! Edit: So far I have come up with just the obvious... Where did you receive your education? What languages are you familiar with? How long have you been tutoring? What made you decide to become a tutor? What software projects have you worked on? What work references can you give me? How much do you charge?

  • Are first-class functions a substitute for the Strategy pattern?

    - by Prog
    The Strategy design pattern is often regarded as a substitute for first-class functions in languages that lack them. So for example say you wanted to pass functionality into an object. In Java you'd have to pass in the object another object which encapsulates the desired behavior. In a language such as Ruby, you'd just pass the functionality itself in the form of an annonymous function. However I was thinking about it and decided that maybe Strategy offers more than a plain annonymous function does. This is because an object can hold state that exists independently of the period when it's method runs. However an annonymous function by itself can only hold state that ceases to exist the moment the function finishes execution. So my question is: when using a language that features first-class functions, would you ever use the Strategy pattern (i.e. encapsulate the functionality you want to pass around in an explicit object), or would you always use an annonymous function? When would you decide to use Strategy when you can use a first-class function?

  • Are R&D mini-projects a good activity for interns?

    - by dukeofgaming
    I'm going to be in charge of hiring some interns for our software department soon (automotive infotainment systems) and I'm designing an internship program. The main productive activity "menu" I'm planning for them consists of: Verification testing Writing Unit Tests (automated, with an xUnit-compliant framework [several languages in our projects]) Documenting Code Updating wiki Updating diagrams & design docs Helping with low priority tickets (supervised/mentored) Hunting down & cleaning compiler/run-time warnings Refactoring/cleaning code against our coding standards But I also have this idea that having them do small R&D projects would be good to test their talent and get them to have fun. These mini-projects would be: Experimental implementations & optimizations Proof of concept implementations for new technologies Small papers (~2-5 pages) doing formal research on the previous two points Apps (from a mini-project pool) These kinds of projects would be pre-defined and very concrete, although new ideas from the interns themselves would be very welcome. Even if a project is too big or is abandoned, the idea would also be to lay the ground work so they can be retaken by another intern or intern team. While I think this is good in concept, I don't know if it could be good in practice, as obviously this would diminish their productivity on "real work" (work with immediate value to the company), but I think it could help bring aboard very bright people and get them to want to stay in the future (which, I think, is the end goal for any internship program). My question here is if these activities are too open ended or difficult for the average intern to accomplish and if R&D is an efficient use of an interns time or if it makes more sense for to assign project work to interns instead.

  • How to avoid game objects accidentally deleting themselves in C++

    - by Tom Dalling
    Let's say my game has a monster that can kamikaze explode on the player. Let's pick a name for this monster at random: a Creeper. So, the Creeper class has a method that looks something like this: void Creeper::kamikaze() { EventSystem::postEvent(ENTITY_DEATH, this); Explosion* e = new Explosion; e->setLocation(this->location()); this->world->addEntity(e); } The events are not queued, they get dispatched immediately. This causes the Creeper object to get deleted somewhere inside the call to postEvent. Something like this: void World::handleEvent(int type, void* context) { if(type == ENTITY_DEATH){ Entity* ent = dynamic_cast<Entity*>(context); removeEntity(ent); delete ent; } } Because the Creeper object gets deleted while the kamikaze method is still running, it will crash when it tries to access this->location(). One solution is to queue the events into a buffer and dispatch them later. Is that the common solution in C++ games? It feels like a bit of a hack, but that might just be because of my experience with other languages with different memory management practices. In C++, is there a better general solution to this problem where an object accidentally deletes itself from inside one of its methods?

  • What kind of language will replace C++ as C++ replaced C ? [closed]

    - by jokoon
    I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.

  • Oracle ADF and Simplified UI Apps: I18n Feng Shui on Display

    - by ultan o'broin
    I demoed the Hebrew language version of Oracle Sales Cloud Release 8 live in Israel recently. The crowd was yet again wowed by the simplified UI (SUI). I’ve now spent some time playing around with most of the 23 language versions, or the NLS (Natural Language Support) versions as we’d call them, available in Release 8. Hebrew Oracle Sales Cloud Release 8 The simplified UI is built using 100% Oracle ADF. This framework is a great solution for developers to productively build tablet-first, mobility-driven apps for users who work and live using natural languages other than English. Oracle ADF’s internationalization (i18n) relies on built-in Java and Unicode,  packing in i18n goodness such as Bi-Di (or bi-directional) flipping of pages, locale-enabled resource bundles, date and time support, and so on. Comparing German (left) and Hebrew Bi-Di (right) page components in the simplified UI. Note the change in the direction of the arrows and positions of the text. So, developers who need to build global apps don’t have to do anything special when using Oracle ADF components, all thanks to the baked-in UX Feng Shui, as Grant Ronald of the ADF team would say to the UK Oracle User Group. Find out more  about  ADF i18n from Frédéric Desbiens (@blueberrycoder)  on the ADF Architecture TV channel.
