• Should a web designer know server-side coding?

  - by Rasoul Zabihi

  We're implementing an CMS based on ASP.NET MVC. Now, any designer should be able to provide themes for this CMS. But to write a theme, they need to be able to modify the generated HTML, thus the concept of View. In other words, they should be capable to either modify current views, or create new views from scratch, to fit their requirements. However, now we're not sure that we're taking the right path. Should a web designer (HTML, CSS, JavaScript + Photoshop) really know about server-side platforms like Razor or PHP, or classic ASP, or anything else?

• Java dev learning Python: what concepts do I need to wrap my head around?

  - by LRE

  I've run through a few tutorials and written some small projects. I'm right in the middle of a small project now infact. All is going well enough thanks in no small part to Uncle Google (who usually points me to Stackoverflow ;-) Several times in the last few days I've found myself wondering "what am I missing?" - I feel that I'm still thinking in Java as I write in Python. This question over at StackOverflow is full of tips about what resources to read up on for learning Python, but I still feel that I'm a Java dev with a dictionary (no pun intended) to translate into Python. What I really want to do is refactor my head to be able to write Pythonic Python instead of Java disguised as Python (not that I want to loose my Java skills). So, the crux of my question is: what concepts does a Java dev really need to learn to think Pythonic? This includes anything that needs to be un-learnt. ps: I consider language syntax to not be particularly relevant to this question.

• My Only Gripe With Programming

  - by David Espejo

  Is that im having trouble practicing problems. Even if I decide to practice the problems from my C++ book, they dont give any idea of the way the solution(program) should look like, so that I may compare to see if my program is similar in anyway. My book gives me to many generic "Write a program to do "this" " projects without really showing a concrete example of what "this" really is. In other words How Do I Know That I did "that". One problem in my book said to write a program that calculates the sales tax on a given item????? First of all slase tax differs on state(whats the state,) whats the item(a house, a dog,) How can I check this to see if im right. Programming books dont have answer keys! I know that there is no ABSOLUTE answer, thats just silly, programs can be written in many ways, but a sample of what one would look like based of the difficulty of the problem would really help! Is there a solution to this, maby a book that has worked out examples for the problems they give , or online sources that do something similar.(is there such thing as a programming book with an answer key?)

• Using C++ but not using the language's specific features, should switch to C?

  - by Petruza

  I'm developing a NES emulator as a hobby, in my free time. I use C++ because is the language I use mostly, know mostly and like mostly. But now that I made some advance into the project I realize I'm not using almost any specific features of C++, and could have done it in plain C and getting the same result. I don't use templates, operator overloading, polymorphism, inheritance. So what would you say? should I stay in C++ or rewrite it in C? I won't do this to gain in performance, it could come as a side effect, but the idea is why should I use C++ if I don't need it? The only features of C++ I'm using is classes to encapsulate data and methods, but that can be done as well with structs and functions, I'm using new and delete, but could as well use malloc and free, and I'm using inheritance just for callbacks, which could be achieved with pointers to functions. Remember, it's a hobby project, I have no deadlines, so the overhead time and work that would require a re-write are not a problem, might be fun as well. So, the question is C or C++?

• What are options for 3rd Party Centralized Software Settings Management?

  - by Jeff Martin

  I am an architect in an enterprise looking to build a SaaS solution. Our products are distributed over many different deployable containers, Web Services, Web UI's, etc. I am looking for some open-source or 3rd party software solution to manage the settings of our application. These would be similar to the settings you might find in Word or Eclipse or Visual Studio. The settings would control various behaviors and features of the product. (Probably not settings like which database to connect to but more like, should I show line numbers on the page or not by default..). Ideally, we would be able to store values for different dimensions (by tenant, by user, by application environment... ) Because we have so many different deployables, I am looking for a centralized solution that can provide a web service that each of the deployables can get their individual settings from. Does anyone know of a centralized service providing this sort of features or give me some help in searching for an alternative to rolling our own?

• how to convince other we should move to hadoop?

  - by Ramy

  Everything I've read about Hadoop seems like exactly the technology we need to make our enterprise more scalable. We have terabytes of raw data that is in non-relational form (text files of some kind). We're quickly approaching the upper limits of what our centralized file server can handle and everyone is aware of this. Most people on the tech team, especially the more junior members of the tech team are all in favor of moving from the central file system to HDFS. The problem is, there is one key (most senior, etc.) member of the team who is resisting this change and every time Hadoop comes up, he tells us that we could simply add another file server and be in the clear. So, my question (and yes, it's really subjective, but I need more help with this than any of my other questions) is what steps can we take to get upper management to move forward with Hadoop despite the hesitation of one member of the team?

• What should I do when my team leader is unfair for no reason? [closed]

  - by crucified soul

  I'm a new software developer and this is my first job. It's a startup and the CEO and the working environment is just great. I work really hard and I believe that I also do my job well. But recently, I have felt like my team leader is being unfair to me for no reason. It appears that he is nice to my co-workers, but not me. I figure he is mad at me, but I didn't bother to find out why. I really love this company and I really love working there. But if my team leader continues to be unfair then I have no option other than leaving. How can I fix this? EDIT: The other day he called me into his office and wanted to see my work in the afternoon (Yes, in my country, at summer season after 5PM is afternoon. My office begins at 8AM. And I'm not saying I've problems to work after 5PM). At the time I was facing a weird runtime error and I was pretty tired. I explained the situation to him. Then he found a small logical error in my code and asked me why I didn't fix this. I told him I was trying to resolve this runtime error and that I was sure that this logical error had nothing to do with the runtime error. He then proceeded to yell at me. After fixing the logical error that runtime error was still there. This is not the only occasion he has been unfair to me. I'm saying is being unfair because he doesn't do this kind of thing to other developers when they do really silly mistakes.

• How does PhP internally represent string?

  - by Jim Thio

  UTF8? UTF16? Does the string in PhP also keep tracks the encoding used for that string? A good answer would give me a sample of Let's look at this script for example. Say I do $original = "??????????????"; What actually happen? Obviously I think $original will not contain just 7 characters. Those glyps must each be represented by several bytes there. Then I do $converted= mb_convert_encoding ($original , "UTF-8") What will happen to $converted? How will $converted be different than $original? Will it be just the exact same byte sequence with $original but with different encoding? Or what?

• How do I know if I am using Scrum methodologies?

  - by Jake

  When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

• Dealing with the node callback pyramid

  - by thecoop

  I've just started using node, and one thing I've quickly noticed is how quickly callbacks can build up to a silly level of indentation: doStuff(arg1, arg2, function(err, result) { doMoreStuff(arg3, arg4, function(err, result) { doEvenMoreStuff(arg5, arg6, function(err, result) { omgHowDidIGetHere(); }); }); }); The official style guide says to put each callback in a separate function, but that seems overly restrictive on the use of closures, and making a single object declared in the top level available several layers down, as the object has to be passed through all the intermediate callbacks. Is it ok to use function scope to help here? Put all the callback functions that need access to a global-ish object inside a function that declares that object, so it goes into a closure? function topLevelFunction(globalishObject, callback) { function doMoreStuffImpl(err, result) { doMoreStuff(arg5, arg6, function(err, result) { callback(null, globalishObject); }); } doStuff(arg1, arg2, doMoreStuffImpl); } and so on for several more layers... Or are there frameworks etc to help reduce the levels of indentation without declaring a named function for every single callback? How do you deal with the callback pyramid?

• What makes Erlang suitable for cloud applications?

  - by Duncan

  We are starting a new project and implementing on our corporations's instantiation of an openstack cloud (see http://www.openstack.org/). The project is security tooling for our corporation. We currently run many hundreds of dedicated servers for security tools and are moving them to our corporations instantiation of openstack. Other projects in my company currently use erlang in several distributed server applications, and other Q/A point out erlang is used in several popular cloud services. I am trying to convince others to consider where it might be applicable on our project. What are erlang's strengths for cloud programming? Where are areas it is particularly appropriate to use erlang?

• Tips or techniques to use when you don't know how to code something?

  - by janoChen

  I have a background as UI designer. And I realized that it is a bit hard for me to write a pieces of logic. Sometimes I get it right, but most of the time, I end up with something hacky (and it usually takes a lot of time). And is not that I don't like programming, in fact, I'm starting to like it as much as design. It's just that sometimes I think that I'm better at dealing with colors an shapes, rather than numbers and logic (but I want to change that). What I usually do is to search the solution on the Internet, copy the example, and insert it into my app (I know this is not a very good practice). I've heard that one tip was to write the logic in common English as comment before writing the actual code. What other tips and techniques I can use?

• correct way to implement auth/acl in mvc

  - by WiseStrawberry

  I am looking into making a correctly laid out MVC auth/acl system. I think I want the authentication of a user (and the session handling) to be seperate from the ACL system. (I don't know why but this seems a good idea from the things I've read) What does mvc have to do with this question you ask? Because I wish for the application to be well integrated with my acl. An example of a controller (CodeIgniter) <?php class forums extends MX_Controller { $allowed = array('users', 'admin'); $need_login = true; function __construct() { //example of checking if logged in. if($this->auth->logged_in() && $this->auth->is_admin()) { echo "you're logged in!"; } } public function add_topic() { if($this->auth->allowed('add_topic') { //some add topic things. } else { echo 'not allowed to add topic'; } } } ?> My thoughts $this->auth would be autoloaded in the system. I would like to check the $allowed array against the user currently (not) logged in and react accordingly. Is this a good way of doing things? I haven't seen much literature on mvc integration and auth. I want to make things as easy as possible.

• Java Terms that are Plagued with Vaguery

  - by Adam Tannon

  What's the difference between a Java Process (what your OS sees) and a JVM? Are they one in the same or are they actually different? How are the JRE and JDK different (in purpose and file content), and which one contains the libraries for Java SE? What's the difference between the Java "Runtime" and a JVM? These are questions I've been asking myself (and colleagues) for years and everybody seems to have very different answers.

• How does a government development shop transition to developing open source solutions?

  - by Rob Oesch

  Our shop has identified several reasons why releasing our software solutions to the open source community would be a good idea. However, there are several reasons from a business stand point why converting our shop to open source would be questioned. I need help from anyone out there who has gone through this transition, or is in the process. Specifically a government entity. About our shop: - We develop and support web and client applications for the local law enforcement community. - We are NOT a private company, rather a public sector entity Some questions that tend to come about when we have this discussion are: We're a government agency, so isn't our code already public? How do we protect ourselves from being 'hacked' if someone looks into our code? (There are obvious answers to this question like making sure you don't hard code passwords, etc. However, the discussion needs to consider an audience of executives who are very security conscience.)

• Top ten most active programming sites to run an ad campaign [closed]

  - by fabbianni

  Hello friends, I'm looking for a new investment in the programming area, I'd like to know about the state of the art in the programming sites you usually visite, like stackoverflow. Not sure if sites like thecodeproject (and similar) are too old fashioned these days. I'm a programmer, but honestly haven't been too involved in the programming arena mostly for admin issues. I'm looking for sites with both great audience and great content, and open to ads, again, like stackoverflow. thanks !

• What is the worst software bug in history? [closed]

  - by Amir Rezaei

  By having for example money and human suffering as the metric. What is the worst software bug in history? Note this is a specific question. Last month automaker Toyota announced a recall of 160,000 of its Prius hybrid vehicles following reports of vehicle warning lights illuminating for no reason, and cars' gasoline engines stalling unexpectedly. But unlike the large-scale auto recalls of years past, the root of the Prius issue wasn't a hardware problem -- it was a programming error in the smart car's embedded code. The Prius had a software bug.

• How to solve linear recurrences involving two functions?

  - by Aditya Bahuguna

  Actually I came across a question in Dynamic Programming where we need to find the number of ways to tile a 2 X N area with tiles of given dimensions.. Here is the problem statement Now after a bit of recurrence solving I came out with these. F(n) = F(n-1) + F(n-2) + 2G(n-1), and G(n) = G(n-1) + F(n-1) I know how to solve LR model where one function is there.For large N as is the case in the above problem we can do the matrix exponentiation and achieve O(k^3log(N)) time where k is the minimum number such that for all km F(n) does not depend on F(n-k). The method of solving linear recurrence with matrix exponentiation as it is given in that blog. Now for the LR involving two functions can anyone suggest an approach feasible enough for large N.

• Software architecture for two similar classes which require different input parameters for the same method

  - by I Like to Code

  I am writing code to simulate a supply chain. The supply chain can be simulated in either an intermediate stocking or a cross-docking configuration. So, I wrote two simulator objects IstockSimulator and XdockSimulator. Since the two objects share certain behaviors (e.g. making shipments, demand arriving), I wrote an abstract simulator object AbstractSimulator which is a parent class of the two simulator objects. The abstract simulator object has a method runSimulation() which takes an input parameter of class SimulationParameters. Up till now, the simulation parameters only contains fields that are common to both simulator objects, such as randomSeed, simulationStartPeriod and simulationEndPeriod. However, I now want to include fields that are specific to the type of simulation that is being run, i.e. an IstockSimulationParameters class for an intermediate stocking simulation, and a XdockSimulationParameters class for a cross-docking simulation. My current idea is take the method runSimulation() out of the AbstractSimulator class, but to put a runSimulation(IstockSimulationParameters) method in the IstockSimulator class, and a runSimulation(XdockSimulationParameters) method in the IstockSimulator class. I am worried however, that this approach will lead to code duplication. What should I do?

• What will be correct answer to "why is NoSQL faster than SQL" on interview?

  - by Cynede

  It's just nonsense for me personally. I can't see any performance boost by using NoSQL instead of SQL. Maybe SQL over NoSQL, yes but not in that way. I think that if I answer "I have no idea" or something like that it will be bad answer because this doesn't really look like a fake-question, it's a serious question on interview but how should be looking correct answer on this question? Or am I missing something about NoSQL?

• Lead Programmer definition clarification

  - by Junaid

  I am working on PHP and MySQL based web application for more than 5 years now. I started my career from Intern - Jr Developer - Software Developer - Sr. Software Engineer [Team Lead] that's what I am nowadays. I was looking at the link at Wikipedia regarding who is a lead programmer. The link states the following: A lead programmer is a software engineer in charge of one or more software projects. Alternative titles include Development Lead, Technical Lead, Senior Software Engineer, Software Design Engineer Lead (SDE Lead), Software Manager, or Senior Applications Developer. When primarily contributing in a high-level enterprise software design role, the title Software Architect (or similar) is often used. All of these titles can have different meanings depending on the context. My current job responsibilities are more or less like a Development Lead and to some extent near Software Architect because I usually design the core structure of new products and managing 2-3 project simultaneously and in the meantime involved in assisting other teams regarding the structural design of their projects, I am usually on call with clients along with project managers, I code most of the time when my team stuck somewhere / workload / integrating some third party API and etc. Primary reason of this writing is to know if I qualify for a Development Lead Title? in accordance with my above mentioned job descriptions?

• for an ajax heavy web application which would be better SOAP or REST?

  - by coder

  I'm building an ajax heavy application (client-side strictly html/css/js) which will be getting all the data and using server business logic via webservices. I know REST seems to be the hot topic but I can't find any good arguments. The main argument seems to be its "light-weight". My impression so far is that wsdl/soap based services are more expressive and allow for more a more complex transfer of data. It appears that soap would be more useful in the application I'm building where the only code consuming the services will be the js downloaded in the client browser. REST on the other hand seems to have a smaller entry barrier and so can be more useful for services like twitter in allowing other developers to consume these services easily. Also, REST seems to Te better suited for simple data transfers. So in summary SOAP is useful for complex data transfer and REST is useful in simple data transfer. I'm currently under the impression that using SOAP would be best due to the complexity of the messages but perhaps there's other factors. What are your thoughts on the pros/cons of soap/rest for a heavy ajax web app?

• What is upcasting/downcasting?

  - by acidzombie24

  When learning about polymorphism you commonly see something like this class Base { int prv_member; virtual void fn(){} } class Derived : Base { int more_data; virtual void fn(){} } What is upcasting or downcasting? Is (Derived*)base_ptr; an upcast or downcast? I call it upcast because you are going away from the base into something more specific. Other people told me it is a downcast because you are going down a hierarchy into something specific with the top being the root. But other people seem to call it what i call it. When converting a base ptr to a derived ptr is it called upcasting or downcasting? and if someone can link to an official source or explain why its called that than great.

• What language has the best/most library bindings?

  - by Rook

  A library binding allows a programming language to use a library written in another language. Most commonly you want to access a C library like libcurl from a language like PHP or Python. Not all bindings are created equally, for instance the libcurl binding for Python was abandoned almost 3 years ago and their sf.net bug tracker is overrun with unsolved problems. PHP on the other hand has very good libcurl bindings that are actively maintained. So here is my question: What language has the best and/or the most bindings?
