• Should a Python programmer learn Ruby?

  - by C J

  Hi! I have been a Python programmer for around 1.5 years (one internship + side projects), so I am comfortable with the language. Given that everyone is talking about Ruby these days, and I mean seriously! No one bothers about Python (from what I've seen). See GitHub. All RoR. I apply for a job and they ask me about RoR. I look at the screencasts on peepcode.com and they are in Ruby. gitimmersion.com has all the tutorial in Ruby! I know this is pretty vague, but still... why Ruby! Everyone these days is obssessed with RoR! Why not Python? Anyways, my questions are: Should I learn Ruby? Is learning Ruby when knowing Python be, er, complicated for me? Or is it going to be just like learning any other language? Thanks!

• Is donationware a good monetization model for developers?

  - by Nathan Campos

  I've been developing for Android for about 2 years (and ~1 year for iOS), releasing freeware and open source applications (mostly because my AdSense account was disabled in 2010), but recently I had an idea for a great app that I wanted to get some money, since it would take some effort to develop and also I would like to test this "commercial" model to know if this could make me invest more time improving and making my apps better. Since my AdSense account was disabled and then I'll not be about to sell it on the Google Play Store, I thought about making it a donationware so I would distribute it for free (and probably open source too) and users that really liked the app and wanted to give me a thanks and a incentive to continue developing it could donate any amount of money. So, what's your experience with donationware? Is it worth compared to paid apps?

• Where to draw the line between development-led security and administration-led security?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers who do not listen to this attribute, strange hacks *\ are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingenuity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• Is it possible to implement an infinite IEnumerable without using yield with only C# code?

  - by sinelaw

  This isn't a practical problem, it's more of a riddle. Problem I'm curious to know if there's a way to implement something equivalent to the following, but without using yield: IEnumerable<T> Infinite<T>() { while (true) { yield return default(T); } } Rules You can't use the yield keyword Use only C# itself directly - no IL code, no constructing dynamic assemblies etc. You can only use the basic .NET lib (only mscorlib.dll, System.Core.dll? not sure what else to include). However if you find a solution with some of the other .NET assemblies (WPF?!), I'm also interested. Don't implement IEnumerable or IEnumerator. Notes The closest I've come yet: IEnumerable<int> infinite = null; infinite = new int[1].SelectMany(x => new int[1].Concat(infinite)); This is "correct" but hits a StackOverflowException after 14399 iterations through the enumerable (not quite infinite). I'm thinking there might be no way to do this due to the CLR's lack of tail recursion optimization. A proof would be nice :)

• Security programming jobs

  - by Mike Smith

  I am a student, about to finish my undergraduate in Computer Science in about a year. I am very interested in computer/network security, but I also love programming. Is there a job or subfield that is a fusion of both? I have programmed everything from games to barcode readers to web bots, and I know for sure that I want to do some kind of programming, but ideally I would like to do some kind of software development involving computer security. Any advice would be appreciated.

• Selling your services when you use uncommon technologies

  - by speeder

  I took a look in Stackoverflow most popular profiles, and then I did the same in several other sites, and then I took a look in job postings in several boards, mostly out of curiosity, because I noticed this: If you work with Java, .NET or other managed languages, or you work with stuff that is popular for web development (Ruby, JavaScript, etc...) you can get lots of points on Stackoverflow, find lots of jobs and clients, find forums, friends, colleagues, etc... But how a programmer of uncommon languages (Lua, pure C, Lisp, D, ADA, Haskell, etc...) find information, sell his services, and so on? EDIT: This also applies to fields: You work with web, corporate software, database, etc... it is great... You dislike those previous 3, noone ever will hire your services...

• Would this violate any copyright issues?

  - by Farhad

  I am currently publishing a paper on skin detection. However, I need to find the appropriate histogram bin size for each colorspace. I recently came upon a paper that published what it found to be the ideal bin size. The paper can be found at: http://www.inf.pucrs.br/~pinho/CG/Trabalhos/DetectaPele/Artigos/OPTIMUM%20COLOR%20SPACES%20FOR%20SKIN%20DETECTION.pdf. I am specifically talking about Table 1. If I cite the source, would it be okay for me to use data from the table? Note that I cannot contact the author of the paper.

• Ajax application: using SOAP vs 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? EDIT: While the wsdl is in xml, the data I'm transferring back and forth is actually in JSON. It just appears more natural to use wsdl/soap here due to the nature of the app. The verbs GET and POST may not be enough. I may want to say something like: processQueue, or executeTimer. This is why my conclusion has been wsdl/soap would be good for bridging a complex layer between two applications (client and server) whereas REST would be better (due to its simplicity) for allowing many developer-users to consume resources programmatically. So you could say the choice falls along two lines Will the app be verb-oriented (completing tasks: use soap) or noun-oriented (consuming resources: use REST) Will the api be consumed by few developers or many developers (REST is strong for many developers)? Since such an ajax heavy app would potentially use many verbs and would only be used by the client developer it appears soap/wsdl would be the best fit.

• Architecture advice for converting biz app from old school to new school?

  - by Aaron Anodide

  I've got a WinForms business application that evolved over the past few years. It's forms over data with a number custom UI experiences taylored to the business, so I don't think it's a candidate to port to something like SharePoint or re-write in LightSwitch (at least not without significant investment). When I started it in 2009 I was new to this type of development (coming from more low level programming and my RDBMS knowledge was just slightly greater than what I got from school). Thus, when I was confronted with a business model that operates on a strict monthly accounting cycle, I made the unfortunate decision to create a separate database for each accounting period. Also, when I started I knew DataSets, then I learned Linq2Sql, then I learned EntityFramework. The screens are a mix and match of those. Now, after a few years developing this thing by myself I've finally got a small team. Ultimately, I want a web front end (for remote access to more straight up screens with grids of data) and a thick client (for the highly customized interfaces). My question is: can you offer me some broad strokes architecture advice that will help me formulate a battle plan to convert over to a single database and lay the foundations for my future goals at the same time? Here's a screen shot showing how an older screen uses DataSets and a newer screen uses EF (I'm thinking this might make it more real for someone reading the question - I'm willing to add any amount of detail if someone is willing to help).

• Geographically limited / gradual release process

  - by daniel.sedlacek

  I am looking for more information on a gradual release process - that is when you release new version of a software only to certain set of end users, mostly geographically limited (or limited by a reach of particular server). Google seems to be blind to this term - that indicates that's not how it's called. What's the name then? EDIT: An example of what I mean is when Facebook rolled out new image galleries they were first visible to certain users only, then to whole US and then to the rest of the world.

• WCF and Service Registry

  - by TK Lee

  I am about to build some WCF Services. Those services need to communicate to each others too, in some scenarios. I've done some "Google-ing" about Service Registry but can't figure out how to implement service registry with WCF; is there any other alternate? Is there any Microsoft technology available for Service Registry? I'm new to SOA and I will really appreciate any help or guidance (what and where should I exactly look for registry services).

• Donald Ferguson says end-user programming is next big thing. Is it?

  - by Joris Meys

  You can guess how I came to ask this question... Anyway : http://www.bbc.co.uk/news/business-11944966 Donald Ferguson claiming that his websphere was his biggest disaster and proclaiming that end-user programming will be the way forward. This genuinely spurs the question : what with current programming languages. Honestly, I don't think that end-user programming will go much beyond a rather rigid template where you can build some apps around. If you see how many people actually manage to understand the basic functionality of functions in EXCEL... Plus, I fail to see how complex and performant systems can be built in such an end-user programming language ( Visual Basic, anyone?) Nice to play around with, but for many applications they're just not the thing. So no worries for the old languages if you ask me. What's your ideas?

• Windows Mobile Interview Question Categories

  - by Ramesh Patel

  I need to set categories for interviewing candidates for Windows Mobile Development. Like for ASP.NET, we can have OOPS .NET Framework (CLR, BCL, MSIL etc) Javascript, jQuery Data Controls ADO.NET SQL Server For Windows Mobile, which are categories that should be included? Being specific to our current product, it has not UI and will run in background. Security is the first thing to take into account. It is a SPY kind of application that will keep track of user activity. It can be used by companies to monotor their employees.

• Combining template method with strategy

  - by Mekswoll

  An assignment in my software engineering class is to design an application which can play different forms a particular game. The game in question is Mancala, some of these games are called Wari or Kalah. These games differ in some aspects but for my question it's only important to know that the games could differ in the following: The way in which the result of a move is handled The way in which the end of the game is determined The way in which the winner is determined The first thing that came to my mind to design this was to use the strategy pattern, I have a variation in algorithms (the actual rules of the game). The design could look like this: I then thought to myself that in the game of Mancala and Wari the way the winner is determined is exactly the same and the code would be duplicated. I don't think this is by definition a violation of the 'one rule, one place' or DRY principle seeing as a change in rules for Mancala wouldn't automatically mean that rule should be changed in Wari as well. Nevertheless from the feedback I got from my professor I got the impression to find a different design. I then came up with this: Each game (Mancala, Wari, Kalah, ...) would just have attribute of the type of each rule's interface, i.e. WinnerDeterminer and if there's a Mancala 2.0 version which is the same as Mancala 1.0 except for how the winner is determined it can just use the Mancala versions. I think the implementation of these rules as a strategy pattern is certainly valid. But the real problem comes when I want to design it further. In reading about the template method pattern I immediately thought it could be applied to this problem. The actions that are done when a user makes a move are always the same, and in the same order, namely: deposit stones in holes (this is the same for all games, so would be implemented in the template method itself) determine the result of the move determine if the game has finished because of the previous move if the game has finished, determine who has won Those three last steps are all in my strategy pattern described above. I'm having a lot of trouble combining these two. One possible solution I found would be to abandon the strategy pattern and do the following: I don't really see the design difference between the strategy pattern and this? But I am certain I need to use a template method (although I was just as sure about having to use a strategy pattern). I also can't determine who would be responsible for creating the TurnTemplate object, whereas with the strategy pattern I feel I have families of objects (the three rules) which I could easily create using an abstract factory pattern. I would then have a MancalaRuleFactory, WariRuleFactory, etc. and they would create the correct instances of the rules and hand me back a RuleSet object. Let's say that I use the strategy + abstract factory pattern and I have a RuleSet object which has algorithms for the three rules in it. The only way I feel I can still use the template method pattern with this is to pass this RuleSet object to my TurnTemplate. The 'problem' that then surfaces is that I would never need my concrete implementations of the TurnTemplate, these classes would become obsolete. In my protected methods in the TurnTemplate I could just call ruleSet.determineWinner(). As a consequence, the TurnTemplate class would no longer be abstract but would have to become concrete, is it then still a template method pattern? To summarize, am I thinking in the right way or am I missing something easy? If I'm on the right track, how do I combine a strategy pattern and a template method pattern? This is part of a homework assignment but I'm not looking to be gifted the answer, I have deliberately been very verbose in my question to show that I have thought about it before coming here to ask a question

• Increase application performance

  - by Prayos

  I'm writing a program for a company that will generate a daily report for them. All of the data that they use for this report is stored in a local SQLite database. For this report, the utilize pretty much every bit of the information in the database. So currently, when I query the datbase, I retrieve everything, and store the information in lists. Here's what I've got: using (var dataReader = _connection.Select(query)) { if (dataReader.HasRows) { while (dataReader.Read()) { _date.Add(Convert.ToDateTime(dataReader["date"])); _measured.Add(Convert.ToDouble(dataReader["measured_dist"])); _bit.Add(Convert.ToDouble(dataReader["bit_loc"])); _psi.Add(Convert.ToDouble(dataReader["pump_press"])); _time.Add(Convert.ToDateTime(dataReader["timestamp"])); _fob.Add(Convert.ToDouble(dataReader["force_on_bit"])); _torque.Add(Convert.ToDouble(dataReader["torque"])); _rpm.Add(Convert.ToDouble(dataReader["rpm"])); _pumpOneSpm.Add(Convert.ToDouble(dataReader["pump_1_strokes_pm"])); _pumpTwoSpm.Add(Convert.ToDouble(dataReader["pump_2_strokes_pm"])); _pullForce.Add(Convert.ToDouble(dataReader["pull_force"])); _gpm.Add(Convert.ToDouble(dataReader["flow"])); } } } I then utilize these lists for the calculations. Obviously, the more information that is in this database, the longer the initial query will take. I'm curious if there is a way to increase the performance of the query at all? Thanks for any and all help. EDIT One of the report rows is called Daily Drilling Hours. For this calculation, I use this method: // Retrieves the timestamps where measured depth == bit depth and PSI >= 50 public double CalculateDailyProjectDrillingHours(DateTime date) { var dailyTimeStamps = _time.Where((t, i) => _date[i].Equals(date) && _measured[i].Equals(_bit[i]) && _psi[i] >= 50).ToList(); return _dailyDrillingHours = Convert.ToDouble(Math.Round(TimeCalculations(dailyTimeStamps).TotalHours, 2, MidpointRounding.AwayFromZero)); } // Checks that the interval is less than 10, then adds the interval to the total time private static TimeSpan TimeCalculations(IList<DateTime> timeStamps) { var interval = new TimeSpan(0, 0, 10); var totalTime = new TimeSpan(); TimeSpan timeDifference; for (var j = 0; j < timeStamps.Count - 1; j++) { if (timeStamps[j + 1].Subtract(timeStamps[j]) <= interval) { timeDifference = timeStamps[j + 1].Subtract(timeStamps[j]); totalTime = totalTime.Add(timeDifference); } } return totalTime; }

• Why is design by contract considered an alternative to the pseudo programming process?

  - by zoopp

  Right now I'm reading Code Complete by Steve McConnell and in chapter 9 he talks about the Pseudo Programming Process (PPP). From what I've understood, the PPP is a way of programming in which the programmer first writes the pseudo code for the routine he's working on, then refines it up to the point where pretty much each pseudo code line can be implemented in 1-3 lines of code, then writes the code in the designated programming language and finally the pseudo code is saved as comments for the purpose of documenting the routine. In chapter 9.4 the author mentions alternatives to the PPP, one of which is 'design by contract'. In design by contract you basically assert preconditions and postconditions of each routine. Now why would that be considered an alternative? To me it seems obvious that I should use both techniques at the same time and not chose one over the other.

• Reasons to Use a VM For Development

  - by George Stocker

  Background: I work at a start-up company, where one team uses Virtual Machines to connect to a remote server to do their development, and another team (the team I'm on) uses local IIS/SQL Server 2005/Visual Studio installations to conduct work. Team VM is located about 1000 miles from Team Non-VM, and the servers the VMs run off of are located near Team VM (Latency, for those that are wondering, is about 50ms). A person high in the company is pushing for Team Non-VM to use virtual machines for programming, development, and testing. The latter point we agree on -- we want Virtual Machines to test configurations and various aspects of the web application in a 'clean' state. The Problem: What we don't agree on is having developers using RDP to connect to a desktop remotely that contains Visual Studio, SQL Server, and IIS to do the same development we could do locally on our laptops. I've tried the VM set-up, and besides the color issue, there is a latency issue that is rather noticeable, not to mention that since we're a start-up, a good number of employees work from home on occasion with our work laptops, and this move would cut off the laptops. They'd be turned in. Reasons to Use Remote VMs for Development (Not Testing!): Here are the stated reasons that this person wants us to use VMs: They work for TeamVM. They keep the source code "safe". If we want to work from home, we could just use our home PCs. Licenses (I don't know what the argument is, only that it's been used). Reasons not to use Remote VMs for Development: Here are the stated reasons why we don't want to use VMs: We like working from home. We get a lot done on our own time. We're not going to use our Home PCs to do work related stuff. The Latency is noticeable. Support for the VMs (if they go down, or if we need a new VM) takes a while. We don't have administrative privileges on the VM, and are unable to change settings as needed. What I'm looking for from the community is this: What reasons would you give for not using VMs for development? Keep in mind these are remote VMs -- this isn't a VM running on a local desktop. It's using the laptop (or a desktop) as a thin client for a remote VM. Also, on the other side of the coin: Is there something we're missing that makes VMs more palatable for development? Edit: I think 'safe' is used in term of corporate espionage, or more correctly if the Laptop gets stolen, the person who stole would have access to our source code. The former (as we've pointed out, is always going to be a possibility -- companies stop that with litigation, there isn't a technical solution (so far as I can see)). The latter point is ( though I don't know its usefulness in a corporate scenario) mitigated by Truecrypt'ing the entire volume.

• Which points should be covered in basic Bachelors' level C++ course?

  - by Gulshan

  I have a young lecturer friend who is going to take the C++ course for the bachelors' degree in CS. He asked me for some suggestions regarding how the course should be organized. Now I am asking you. I have seen many trends in universities which leads to a nasty experience of C++. So, please suggest from a professional programmer's point of view. For your information, the students going to take the course, have taken course like "Introduction to programming with C" in previous semester.

• What can Haskell's type system do that Java's can't?

  - by Matt Fenwick

  I was talking to a friend about the differences between the type systems of Haskell and Java. He asked me what Haskell's could do that Java's couldn't, and I realized that I didn't know. After thinking for a while, I came up with a very short list of minor differences. Not being heavy into type theory, I'm left wondering whether they're formally equivalent. To try and keep this from becoming a subjective question, I'm asking: what are the major, non-syntactical differences between their type systems? I realize some things are easier/harder in one than in the other, and I'm not interested in talking about those. And to make it more specific, let's ignore Haskell type extensions since there's so many out there that do all kinds of crazy/cool stuff.

• How do I handle a user story that I complete, but with compromise and need to revisit?

  - by ProfK

  I have just fulfilled (is that a good term?) two user stories out of a new project backlog I have just built. These are user registration and password reset, both requiring mail. I need to implement a substitute mail component because my initial choice, and a normally reliable one, wasn't working. Because I was focused on delivering the user stories, not debugging the mail component, I swapped it out to deliver working code at sprint end. Do I now log a new support issue for the mailer, or 're-insert' these stories into the backlog? If I do the latter, am I not introducing too much tech detail into user stories?

• Which simple Java JPA ORM tool to use ?

  - by Guillaume

  What Java ORM library implementing JPA that match following criteria would you recommend and why ? free & open source alive (at least bug fixes and a mailing list) with good documentation simple not hibernate (this one is well-known :-) ) I need to select a simple ORM tool that can be set up in minutes without and easy to understand for setting simple CRUD daos. A query builder ill be an interesting plus. Later I can have to move to Hibernate, that's why being JPA compliant is a must. I have found some candidates on the web, but not so much feedback, so I will gladly take your advices on the topic. ----- EDIT --------- I have been successfully testing ebean/avaje with a small test cases. Any one has a feedback on using this tool in production ?

• How to interview my future team leader?

  - by Stormenet

  Our current team leader is quitting his job (starting his own company) and thus we are searching for a new team leader. It's a small team of 4 people (Team leader included). Since it's a small team we expect the team leader not to only manage us but also do some coding. Because of this I convinced the R&D manager to let me have a say in this so that I can evaluate his technical skills and managing skills. I have little experience interviewing people let alone my future Team leader. What I search in a team leader is someone who isn't running a dictatorship but someone that when there are issues there is a discussion about it and we take everyone on the same line. What are the things I should not forget to ask and what are the skills I should find in that person?

• Battling Emacs Pinky?

  - by haziz

  My problem is not so much emacs pinky as much as having to work with multiple machines, across 3 operating systems, both desktop and laptop, with differing keyboard layouts and different locations for Ctrl and Alt\Meta keys so I often have to pause and think about where is the Ctrl key on this machine. How do you deal with varying keyboard layouts, between Mac keyboards (mostly the laptops) and PC keyboards (mostly 101 keys in my case, yes the original PC keyboard)? I have turned the Caps lock Key into a Ctrl key (losing the Caps lock function completely rather than swapping with Ctrl) on most of them but still find myself hunting for the original Ctrl labeled key most of the time. How do you deal with this keyboard confusion? Suggestions, ideas and feedback welcome.
