• What steps should I follow to start developing website applications?

  - by Oscar Mederos

  Hello, I've been developing desktop applications for about 4 years, using .NET, C++, C, and a little of Python. I've covered lots of topics while developing my applications, and even web technologies (cookies, GET/POST methods, when programming some scrapers/crawlers). I've been always waiting to start developing websites, preferably using PHP + MySQL, although other advises will be welcomed to make this question more useful and generic for others. I know I could use a CMS instead of starting from scratch, but sometimes I don't need an entire CMS to do minor things... What steps should I follow to create a website? Let's suppose I have a web designer. First of all, the designer designs the entire website (CSS, etc) and then I do the programming stuffs, like loading dynamically things from databases, doing some client-side stuffs with javascript, etc? Or how is the best way to do it? Edit: I'm not looking for tools/frameworks/languages suggestions. What I want to know is how a team (or a developer with a designer) starts creating a website. The steps they do, what tasks they do first, how they integrate the work, etc. An example of an answer could be: 1) Design the entire website with good CSS practices, using containers instead of tables in some cases, etc. 2) Use that design and develop the logic or the functionalities of the website. Of course, that's just an example. I'm looking for a good way to approach it, because I've been wanting to start on it but don't really know how exactly to organize the job :/

• Can Foswiki be used as a distributed Redmine replacement? [closed]

  - by Tobias Kienzler

  I am quite familiar with and love using git, among other reasons due to its distributed nature. Now I'd like to set up some similarly distributed (FOSS) Project Management software with features similar to what Redmine offers, such as Issue & time tracking, milestones Gantt charts, calendar git integration, maybe some automatic linking of commits and issues Wiki (preferably with Mathjax support) Forum, news, notifications Multiple Projects However, I am looking for a solution that does not require a permanently accesible server, i.e. like in git, each user should have their own copy which can be easily synchronized with others. However it should be possible to not have a copy of every Project on every machine. Since trac uses multiple instances for multiple projects anyway, I was considering using that, but I neither know how well it adapts to simply giting the database itself (which would be be easiest way to handle the distribution due to git being used anyway), nor does it include all of Redmine's feature. After checking http://www.wikimatrix.org for Wikis with integrated tracking system and RCS support, and filtering out seemingly stale project, the choices basically boil down to Foswiki, TWiki and Ikiwiki. The latter doesn't seem to offer as many usability features, and in the TWiki vs Foswiki issue I tend to the latter. Finally, there is Fossil, which starts from the other end by attempting to replace git entirely and tracking itself. I am however not too comfortable with the thought of replacing git, and Fossil's non-SCM features don't seem to be as developed. Now before I invest too much time when someone else might already have tried this, I basically have two questions: Are there crucial features of Project Management software like Redmine that Foswiki does not provide even with all the extensions available? How to set Foswiki up to use git instead of the perl RcsLite?

• Binary on the Coat of Arms of the Governor General of Canada

  - by user132636

  Can you help me further this investigation? Here is about 10% of the work I have done on it. I present it only to see if there are any truly curious people among you. I made a video a few weeks ago showing some strange things about the Governor General's Coat of Arms and the binary on it. Today, I noticed something kinda cool and thought I would share. Here is the binary as it appears on the COA: 110010111001001010100100111010011 As DEC: 6830770643 (this is easily found on the web) Take a close look at that number. What do you notice about it? It has a few interesting features, but here is the one no one has pointed out... Split it down the middle and you have 68307 70643. The first digit is double the value of the last digit. The second digit is double the second last digit. The third digit is half of the third to last digit. And the middle ones are even or neutral. At first, I thought of it as energy. ++-nnnn+-- But actually you can create something else with it using the values. 221000211. See how that works. You may be asking why that is significant. Bare with me. I know 99% are rolling their eyes. 221000211 as base3 gives you this as binary: 100011101000111 100011101000111 as HEX is 4747, which converts to "GG". Initials of Governor General. GG.ca is his website. When you convert to base 33 (there are 33 digits in the original code) you get "GOV" Interesting? :D There is a lot more to it. I'll continue to show some strange coincidences if anyone is interested. Sorry if I am not explaining this correctly. By now you have probably figured out that I have no background in this. Which is why I am here. Thank you.

• Architecture for interfacing multiple applications

  - by Erwin

  Let's say you have a Master Database and a few External/Internal applications that use WebServices to interface data. What would be your preferred architecture to interface data from and to those applications? Would you put some sort of Enterprise Service Bus in between? Like BizTalk? Or something cheaper? We don't want to block applications while they are interfacing, but we do want to use return codes from the interfaces to determine if we need to take some actions in the originating application or not.

• Is .NET WCF worth the effort?

  - by SnOrfus

  Maybe it's me, but I've never encountered nearly as many problems, annoying challenges, indirect error messages and general frustrations with any other technology as I have with WCF. What are the ACTUAL benefits? Not the MS Press Release benefits of 'a unified architecture for something something that's not going to work anyway.' And are those benefits worth the annoying frustrations? I'm normally a big MS fanboy over here, but I just can't get behind WCF.

• What's wrong with JavaScript

  - by ts01

  There is a lot of buzz around Dart recently, often questioning Google motivations and utility of Dart as replacement for JavaScript. I was searching for rationale of creating Dart rather than investing more effort in ECMAScript. In well known leaked mail its author is saying that Javascript has historical baggage that cannot be solved without a clean break. But there is only one concrete example given (apart of performance concerns) of "fundamental language problems", which is an existence of a single Number primitive So, my questions are: How an existence of a single Number primitive can be a "fundamental problem"? Are there other known "fundamental problems" in JavaScript?

• Why are SW engineering interviews disproportionately difficult?

  - by stackoverflowuser2010

  First, some background on me. I have a PhD in CS and have had jobs both as a software engineer and as an R&D research scientist, both at Very Large Corporations You Know Very Well. I recently changed jobs and interviewed for both types of jobs (as I have done in the past). My observation: SW engineer job interviews are way, way disproportionately more difficult than CS researcher job interviews, but the researcher job is higher paying, more competitive, more rewarding, more interesting, and has a higher upside. Here's a typical interview loop for researcher: Phone interview to see if my research is in alignment with the lab's researcher In-person, give presentation on my recent research for one hour (which represents maybe 9 month's worth of work), answer questions In-person one-on-one interviews with about 5 researchers, where they ask me very reasonable questions on my work/publications/patents, including: technical questions, where my work fits into related work, and how I can extend my work to new areas Here's a typical interview loop for SW engineer: Phone interview where I'm asked algorithm questions and maybe do some coding. Pretty standard. In-person interviews at the whiteboard where they drill the F*** out of you on esoteric C++ minutia (e.g. how does a polymorphic virtual function call work), algorithms (make all-pairs-shortest-path algorithm work for 1B vertices), system design (design a database load balancer), etc. This goes on for six or seven interviews. Ridiculous. Why would anyone be willing to put up with this? What is the point of asking about C++ trivia or writing code to prove yourself? Why not make the SE interview more like the researcher interview where you give a talk about what you've done? How are technical job interviews for other fields, like physics, chemistry, civil engineering, mechanical engineering?

• Types of quotes for an HTML templating language

  - by Ralph

  I'm developing a templating language, and now I'm trying to decide on what I should do with quotes. I'm thinking about having 3 different types of quotes which are all handled differently: backtick ` double quote " single quote ' expand variables ? yes no escape sequences no yes ? escape html no yes yes Backticks Backticks are meant to be used for outputting JavaScript or unescaped HTML. It's often handy to be able to pass variables into JS, but it could also cause issues with things being treated as variables that shouldn't. My variables are PHP-style ($var) so I'm thinking that might mess with jQuery pretty bad... but if I disable variable expansion w/ backticks then, I'm not sure how would insert a variable into a JS code block? Single Quotes Not sure if escape sequences like \n should be treated as literals or converted. I find it pretty rare that I want to disable escape sequences, but if you do, you could use backticks. So I'm leaning towards "yes" for this one, but that would be contrary to how PHP does it. Double Quotes Pretty certain I want everything enabled for this one. Modifiers I'm also thinking about adding modifiers like @ or r in front of the string that would change some of these options to enable a few more combinations. I would need 9 different quotes or 3 quotes and 2 modifiers to get every combination wouldn't I? My language also supports "filters" which can be applied against any "term" (number, variable, string) so you could always write something like "blah blah $var blah"|expandvars Or "my string"|escapehtml Thoughts? What would you prefer? What would be least confusing/most intuitive?

• Linking Libraries in iOS?

  - by Joey Green

  This is probably a totally noob question but I have missing links in my mind when thinking about linking libraries in iOS. I usually just add a new library that's been cross compiled and set the build and linker paths without really know what I'm doing. I'm hoping someone can help me fill in some gaps. Let's take the OpenCV library for instance. I have this totally working btw because of a really well written tutorial( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ), but I'm just wanting to know what is exactly going on. What I'm thinking is happening is that when I build OpenCV for iOS is that your creating object code that gets placed in the .a files. This object code is just the implementation files( .m ) compiled. One reason you would want to do this is to make it hard to see the source code and so that you don't have to compile that source code every time. The .h files won't be put in the library ( .a ). You include the .h in your source files and these header files communicate with the object code library ( .a ) in some way. You also have to include the header files for your library in the Build Path and the Library itself in the Linker Path. So, is the way I view linking libraries correct? If , not can someone correct me on this ?

• Objective C and ios development training courses feedback

  - by Mutuelinvestor

  I'm thinking about taking an Objective C / iphone/ipad development training course. Pragmatic Studio and Big Nerd Ranch appear to be the key players. I'd love to hear any feed back from anyone who has completed training with Pragmatic, Big Nerd or others. I'd interested in quality of instruction, how much you learned, strengths, weaknesses and any other valuable insights. Its a pretty big financial commitment for me and I want to get the most bang for my buck. Thanks in advance for your input.

• ASP.NET AJAX and my axe!

  - by Marlon

  So, I'm seriously considering axing ASP.NET AJAX from my future projects as I honestly feel it's too bloated, and at times convoluted. I'm also starting to feel it is a dying library in the .NET framework as I hardly see any quality components from the open-source community. All the kick-ass components are usually equally bloated commercial components... It was cool at first, but now I tend to get annoyed with it more than anything else. I'm planning on switching over to the jQuery library as just about everything in ASP.NET AJAX is often easily achievable with jQuery, and, more often than not, more graceful of a solution that ASP.NET AJAX and it has a much stronger open-source community. Perhaps, it's just me, but do you feel the same way about ASP.NET AJAX? How was/is your experience working with ASP.NET AJAX?

• Designing a large database with multiple sources

  - by CatchingMonkey

  I have been tasked with redesigning, or at worst optimising the structure of a database for a data warehouse. Currently, the database has 4 other source databases (which is due to expand to X number of others), all of which have their own data structures, naming conventions etc. At the moment an overnight SSIS package pulls the data from the various source and then for each source coverts the data into a standardised, usable format. These tables are then appended to each other creating a 60m row, 40 column beast!. This table is then used in a variety of ways from an OLAP cube to a web front end. The structure has been in place for a very long time, and the work I have been able to prove the advantages of normalisation, and this is the way I would like to go. The problem for me is that the overnight process takes so long I don't then want to spend additional time normalising the last table into something usable. Can anyone offer any insight or ideas into the best way to restructure or optimise the database efficiently? Edit: All the databases are MS SQL Server 2008 R2 Thanks in advance CM

• JavaScript or PHP based WYSIWYG vector based image editor

  - by Jeroen Pluimers

  For a PHP based site of a client, I'm looking for a vector based image editor that allows: end user creation of vectored images consisting of objects supports upload of bitmap images to be used as objects inside the vector image supports adding text objects to add to the vector image, and change properties (font name, font style, font size) of the text objects preferably supports layering or grouping of objects inside the vector image integrates nicely with a PHP based site (so a PHP or JavaScript library is preferred) can store the vector image in SVG, EPS or PDF Both commercial and FOSS solutions are OK. Any idea where to find such a library? --jeroen

• Why do you hate Java? Is it the language or the framework? [closed]

  - by zneak

  According to you all, Java is the third most-hated language here. The two other most hated languages are PHP and VBScript. (It's quite funny how they stand together on the podium.) I'd like to make it known that the question mostly addresses people who don't like Java. I assume here a number of subjective opinions as facts because they're usually considered true among people who don't like Java, and I don't want to be convinced otherwise here. If you're a Java enthusiast, you might find this question frustrating. It's never been made clear if people hate Java itself, or if they hate it because of the framework, or if it's a mixture of the two. On a side you have the language, where you have: the "everything should be an object" philosophy, even in instances where it should obviously be something else (event handlers I'm pointing you); checked exceptions; the idea that all logic should be presented as methods and properties is a big no-no; the fact that "closures" created by anonymous types only include final variables and arguments, but will allow write access to any member of the parent class; a few more. On the other side, you have the JDK, with... its load of inconsistencies and overengineering; monolithic class hierarchies; meaningless base exceptions like IOException (though other frameworks have similar exception hierarchies); sluggish responsiveness even with Swing; a few more. My question is, do you think that, if either one (Java or the JDK) was taken alone, and the other was dropped in favor of something else, the new combination would be better? For instance, if you could use the C# syntax with the JDK (adapting get*/set* methods into properties, and interfaces with only one method into delegates), or the Java syntax with the .NET Framework (doing the inverse transformations), would things get better in your opinion?

• Windows Phone 8 development on Windows 7 - is it or will be possible?

  - by Tiby

  I was trying to install Windows Phone 8 SDK on my Windows 7 machine and it hit me with the 'supported only on Windows 8' message. I actually wanted to develop Phone 7.5 apps on Visual Studio 2012, impossible thing with the 7.1 SDK, so I thought 8 SDK will do the job. As if it was not enough that the 8 SDK was controversial upon release, now that it's generally available, to me it seems like a horrible decision to make it available only for Windows 8, because in my humble opinion, no serious and sane developer will install Windows 8 ever, or at least in the near future, just because of the Metro UI. So, anyone knows any workarounds for developing Windows Phone 8 on Windows 7, or at least develop for 7.5 but using Visual Studio 2012?

• Writing cross-platforms Types, Interfaces and Classes/Methods in C++

  - by user827992

  I'm looking for the best solution to write cross-platform software, aka code that I write and that I have to interface with different libraries and platforms each time. What I consider the easiest part, correct me if I'm wrong, is the definition of new types, all I have to do is to write an hpp file with a list of typedefs, I can keep the same names for each new type across the different platforms so my codebase can be shared without any problem. typedefs also helps me to redefine a better scope for my types in my code. I will probably end up having something like this: include |-windows | |-types.hpp |-linux | |-types.hpp |-mac |-types.hpp For the interfaces I'm thinking about the same solution used for the types, a series of hpp files, probably I will write all the interfaces only once since they rely on the types and all "cross-platform portability" is ensured by the work done on the types. include | |-interfaces.hpp | |-windows | |-types.hpp |-linux | |-types.hpp |-mac | |-types.hpp For classes and methods I do not have a real answer, I would like to avoid 2 things: the explicit use of pointers the use of templates I want to avoid the use of the pointers because they can make the code less readable for someone and I want to avoid templates just because if I write them, I can't separate the interface from the definition. What is the best option to hide the use of the pointers? I would also like some words about macros and how to implement some OS-specifics calls and definitions.

• Is there a procedural graphical programming environment?

  - by Marc

  I am searching for a graphical programming environment for procedural programming in which you can integrate some or all of the common sources of calculation procedures, such as Excel sheets, MATLAB scripts or even .NET assemblies. I think of something like a flowchart configurator in which you define the procedures via drag& drop using flow-statements (if-else, loops, etc.). Do you know of any systems heading in this direction?

• Are there advantages to using a DVCS for a solo developer?

  - by SnOrfus

  Right now, I use visual svn on my server, and have ankhsvn/tortoise on my personal machine. It works fine enough, and I don't have to change, but if I can see some benefits of using a DVCS, then I might give it a go. However, if there's no point or difference using it without other people, then I won't bother. So again, I ask, are there any benefits to using a DVCS when you're the only developer?

• High-Level Application Architecture Question

  - by Jesse Bunch

  So I'm really wanting to improve how I architect the software I code. I want to focus on maintainability and clean code. As you might guess, I've been reading a lot of resources on this topic and all it's doing is making it harder for me to settle on an architecture because I can never tell if my design is the one that the more experienced programmer would've chosen. So I have these requirements: I should connect to one vendor and download form submissions from their API. We'll call them the CompanyA. I should then map those submissions to a schema fit for submitting to another vendor for integration with the email service provider. We'll call them the CompanyB. I should then submit those responses to the ESP (CompanyB) and then instruct the ESP to send that submitter an email. So basically, I'm copying data from one web service to another and then performing an action at the latter web service. I've identified a couple high-level services: The service that downloads data from CompanyA. I called this the CompanyAIntegrator. The service that submits the data to CompanyB. I called this CompanyBIntegrator. So my questions are these: Is this a good design? I've tried to separate the concerns and am planning to use the facade pattern to make the integrators interchangeable if the vendors change in the future. Are my naming conventions accurate and meaningful to you (who knows nothing specific of the project)? Now that I have these services, where should I do the work of taking output from the CompanyAIntegrator and getting it in the format for input to the CompanyBIntegrator? Is this OK to be done in main()? Do you have any general pointers on how you'd code something like this? I imagine this scenario is common to us engineers---especially those working in agencies. Thanks for any help you can give. Learning how to architect well is really mind-cluttering.

• Is unit testing or test-driven development worthwhile?

  - by Owen Johnson

  My team at work is moving to Scrum and other teams are starting to do test-driven development using unit tests and user acceptance tests. I like the UATs, but I'm not sold on unit testing for test-driven development or test-driven development in general. It seems like writing tests is extra work, gives people a crutch when they write the real code, and might not be effective very often. I understand how unit tests work and how to write them, but can anyone make the case that it's really a good idea and worth the effort and time? Also, is there anything that makes TDD especially good for Scrum?

• Studies of Pair Programming on Translation Projects

  - by gmletzkojr

  I am looking for information (ie, studies, metrics, etc) for pair programming when translating a project from an "older" language to a "newer" language. In this particular case, translating means line for line translation where ever possible, and only modifying the design when absolutely necessary, not when the modification would provide improved performance. I have performed pair programming in new development, and I am well aware of the pros and cons of pairing in that environment. However, I haven't been able to find any information in this particular case. Any help is appreciated.

• Better Programming By Programming Better?

  - by ahmed

  I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

• Best practice to propagate preferences of application

  - by Shebuka

  What is your approach with propagation to all classes/windows of preferences/settings of your application? Do you share the preference_manager class to all classes/windows who need it or you make variables in each classes/windows and update them manually each time setting are changed? Currently I have a PreferencesInterface class that hold all preferences and is responsible to default all values with a dedicated method called on create and when needed, all values are public, so non getters/setters, also it have virtual SavePreferences/LoadPreferences methods. Then I have PreferencesManager that extends from PreferencesInterface and is responsible for actually implementation of SavePreferences/LoadPreferences. I've made this basically for cross-platform so that every platform can have a different implementation of actual storage (registry, ini, plist, xml, whatever).

• how to think like a computer scientist java edition exercise 7.2 [on hold]

  - by James Canfield

  I cannot figure out how to write this program, can someone please help me?! The purpose of this method is to practice manipulating St rings. Create a new program called Name.java. This program will take a name string consisting of EITHER a first name followed by a last name (nonstandar d format) or a last name followed by a comma then a first name (standard format). Ie . “Joe Smith” vs. “Smith, Joe”. This program will convert the string to standard format if it is not already in standard format. Write a method called hasComma that takes a name as an argument and that returns a boolean indicating whether it contains a comma. If i t does, you can assume that it is in last name first format. You can use the indexOf String m ethod to help you. Write a method called convertName that takes a name as an argument. It should check whether it contains a comma by calling your hasComma method. If it does, it should just return the string. If not, then it should assume th at the name is in first name first format, and it should return a new string that contains the name converted to last name comma first format. Uses charAt, length, substring, and indexOf methods. In your main program, loop, asking the user for a n ame string. If the string is not blank, call convertName and print the results. The loop terminat es when the string is blank. HINTS/SUGGESTIONS: Use the charAt, length, substring, and indexOf Str ing methods. Use scanner for your input. To get the full line, complete with spaces, use reader.nextLine()
