  • Advise on how to move from a .net developer role to a web developer role

    - by dermd
    I've been working primarily as a .net developer for the past 4 years for a financial services company. I've worked on .net 1.1, 2.0, 3.5 and have done the 3.5 enterprise app developer cert (not that that's worth a whole lot!). Before that I worked as a java developer with a bit of Flex thrown in for just over a year. My educational background is an Electronic and computer engineering degree, a higher diploma in systems analysis as well as one in web development (this was mainly java - JSP, Spring, etc) and a science masters in software design and development. I really feel like a change and would like to move to a different field to experience something different. I've done some courses in RoR and played around with it a bit in my spare time. Similarly I've done various web and mobile courses and done up some mobile webapps along with android and ios equivalents (haven't tried pushing them up to the app stores yet but may be worth tidying them up and doing that). I currently work long enough hours so find it hard to find time to work on too many side projects to get a decent portfolio together. But when I do work on the web stuff I do find it really enjoyable so think it's something I'd like to do full time. However, since my experience is pretty much all .net and financial services I find it very hard to get my foot in the door anywhere or get past a phone screen unless their specifically looking for someone with .net knowledge. What is the best way to move into a web development role without starting from scratch again. I do think a lot of the skills I have translate over but I seem to just get paired with .net jobs whenever I look around? Apart from js, jquery, html5, objective C are there any other technologies I should be looking into?

  • How does Comparison Sites work?

    - by Vijay
    Need your thinking on how does these Comparision Sites actually work. Sites like Junglee.com policybazaar.com and there are many like these which provides comaprision of products , fares etc. grabbed from different websites. I had read a little about it and what i found is-: These sites uses Feeds of the sites data. These sites uses APIs of the sites which are actually provided by those sites. And for some sites which do not have any of these two posibility then the Comparision sites uses web-crawler to crawl their data. This is what i have found out. If you think there is more things to it please do give your own views. But i want to know these for my learning purpose and a little for curiosity- how does they actually matches the crawled data , feeds, and other so that there is no duplicacy. What is the process or algorithms for it. And where should i go to learn these concepts. References for books , articles or anything else.

  • Closest to “Mathematica Graphics[]" drawing environment for Python

    - by 500
    Being only familiar with Mathematica and its Graphics, I have now to learn to draw Graphics using Python for a server. Mostly conditional combination of simple shape. What would be a package for Python that make drawing Graphics as close as possible as the Mathematica Graphics environment ? For Example, I would need to do such thing as in : http://mathematica.stackexchange.com/questions/1010/2d-gaussian-distribution-of-squares-coordinates#comment2475_1010

  • REST: How to store and reuse REST call queries

    - by Jason Holland
    I'm learning C# by programming a real monstrosity of an application for personal use. Part of my application uses several SPARQL queries like so: const string ArtistByRdfsLabel = @" PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT DISTINCT ?artist WHERE {{ {{ ?artist rdf:type <http://dbpedia.org/ontology/MusicalArtist> . ?artist rdfs:label ?rdfsLabel . }} UNION {{ ?artist rdf:type <http://dbpedia.org/ontology/Band> . ?artist rdfs:label ?rdfsLabel . }} FILTER ( str(?rdfsLabel) = '{0}' ) }}"; string Query = String.Format(ArtistByRdfsLabel, Artist); I don't like the idea of keeping all these queries in the same class that I'm using them in so I thought I would just move them into their own dedicated class to remove clutter in my RestClient class. I'm used to working with SQL Server and just wrapping every query in a stored procedure but since this is not SQL Server I'm scratching my head on what would be the best for these SPARQL queries. Are there any better approaches to storing these queries using any special C# language features (or general, non C# specific, approaches) that I may not already know about? EDIT: Really, these SPARQL queries aren't anything special. Just blobs of text that I later want to grab, insert some parameters into via String.Format and send in a REST call. I suppose you could think of them the same as any SQL query that is kept in the application layer, I just never practiced keeping SQL queries in the application layer so I'm wondering if there are any "standard" practices with this type of thing.

  • Do abstractions have to reduce code readability?

    - by Martin Blore
    A good developer I work with told me recently about some difficulty he had in implementing a feature in some code we had inherited; he said the problem was that the code was difficult to follow. From that, I looked deeper into the product and realised how difficult it was to see the code path. It used so many interfaces and abstract layers, that trying to understand where things began and ended was quite difficult. It got me thinking about the times I had looked at past projects (before I was so aware of clean code principles) and found it extremely difficult to get around in the project, mainly because my code navigation tools would always land me at an interface. It would take a lot of extra effort to find the concrete implementation or where something was wired up in some plugin type architecture. I know some developers strictly turn down dependency injection containers for this very reason. It confuses the path of the software so much that the difficulty of code navigation is exponentially increased. My question is: when a framework or pattern introduces so much overhead like this, is it worth it? Is it a symptom of a poorly implemented pattern? I guess a developer should look to the bigger picture of what that abstractions brings to the project to help them get through the frustration. Usually though, it's difficult to make them see that big picture. I know I've failed to sell the needs of IOC and DI with TDD. For those developers, use of those tools just cramps code readability far too much.

  • How do you organize your projects?

    - by Sergio Tapia
    Do you have any particular style of organizing projects? For example, currently I'm creating a project for a couple of schools here in Bolivia, this is how I organized it: TutoMentor (Solution) TutoMentor.UI (Winforms project) TutoMentor.Data (Class library project) How exactly do you organize your project? Do you have an example of something you organized and are proud of? Can you share a screenshot of the Solution pane? In the UI area of my application, I'm having trouble deciding on a good schema to organize different forms and where they belong. Edit: What about organizing different forms in the .UI project? Where/how should I group different form? Putting them all in root level of the project is a bad idea.

  • Deprecated Methods in Code Base

    - by Jamie Taylor
    A lot of the code I've been working on recently, both professionally (read: at work) and in other spheres (read: at home, for friends/family/etc, or NOT FOR WORK), has been worked on, redesigned and re-implemented several times - where possible/required. This has been in an effort to make things smaller, faster more efficient, better and closer to spec (when requirements have changed). A down side to this is that I now have several code bases that have deprecated method blocks (and in some places small objects). I'm looking at making this code maintainable and easy to roll back on changes. I'm already using version control software in both instances, but I'm left wondering if there are any specific techniques that have been used by others for keeping the superseded methods without increasing the size of compiled outputs? At the minute, I'm simply wrapping the old code in C style multi line comments. Here's an example of what I mean (C style, psuedo-code): void main () { //Do some work //Foo(); //Deprecated method call Bar(); //New method } /***** Deprecated code ***** /// Summary of Method void Foo() { //Do some work } ***** Deprecated Code *****/ /// Summary of method void Bar() { //Do some work } I've added a C style example, simply because I'm more confident with the C style languages. I'm trying to put this question across as language agnostic (hence the tag), and would prefer language agnostic answers, if possible - since I see this question as more of a techniques and design question. I'd like to keep the old methods and blocks for a bunch of reasons, chief amongst them being the ability to quickly restore an older working method in the case of some tests failing, or some unforeseen circumstance. Is there a better way to do this (that multi line comments)? Are there any tools that will allow me to store these old methods in separate files? Is that even a good idea?

  • Does software architect/designer require more skills and intellectual than software engineer (implementation)?

    - by Amumu
    So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

  • Traditional ASP.Net WebForms vs ASP.Net MVC

    - by Pankaj Upadhyay
    ASP.Net MVC has been around for some time now. The latest one, i.e MVC3 comes with Razor View Engine. My question: How long is traditional ASP.Net here to stay. Does Microsoft have any plans to eliminate it in aid of ASP.Net MVC in the future and will the next release of VS incorporate it? Also, I would like to know if there is any merit of traditional over ASP.Net MVC, other than the controls-aid?

  • C# coding standards” Use the const directive only on natural constants

    - by Nathan Wilfert
    I've seen these 2 guidelines in coding c# standard and I’m not sure the what the 2nd one means. With the exception of zero and one, never hard-code a numeric value; always declare a constant instead. Use the const directive only on natural constants such as the number of days of the week. 1st what is the definition of a natural constants and if the number is not a natural constants given the 1st rule how does one declare a constant in c# without the const directive? See http://www.scribd.com/doc/10731655/IDesign-C-Coding-Standard-232 for reference.

  • How to keep up to date with Programming Blogs Aggregators

    - by landal79
    Last week I read a great post of Jeff Atwood Keeping Up and "Just In Time" Learning that speaks about how to keep update. The blog post reports Kathy Sierra list, the first item 'Find the best aggregators' has captured my attention. I'm used to look at DZone, IMHO a good aggregator. DZone has voting and tagging. Or recently I discovered Java Code Geeks. Are there any other good programming blog post aggregator?

  • C# Multithreading Interview questions for a senior developer/designer position.

    - by Mohit Bhandari
    I know there have been a great deal of interview questions posted on SO and specifically i like the post "Good C# interview questions for a Senior developer position" But i really wondered what sort of interview questions were asked to a senior developer or technical consultant on multithreading. Kindly provide me some of the interview questions which were asked in the interview on multithreading if possible kindly put the scenario based questions with some theoretical questions. As I came to know after disscusion with some of the people that some time interviewer might give you a scenario and ask you to implement it? @ Kindly add the specific questions which you have ever faced or asked to the other person in the interview other than only mentioning the concepts because people go through the concepts and still find it difficult to handle the interview questions.so any effort to add the specific question could actually help person to get a head start for the d-day

  • If you had to reinvent a new syntax for regular expressions, what would it look like?

    - by Timwi
    Regular expressions as they are today are pretty much as concise and compact as they can be. Consequently, they are often criticised for being unreadable and hard to debug. If you had to reinvent a new syntax for regular expressions, what would it look like? Do you prefer the concise syntax they already have (or a different but similarly concise syntax)? If so, please justify why you think regular expressions deserve to be this concise, but your favourite programming language doesn’t (unless it’s Perl). Or do you think regular expressions should have a slightly more spaced-out syntax and look a bit more like operators and syntax elements normally do in programming languages? If so, provide examples of what you think the syntax should look like, and justify why it is better than the current syntax. Or do you think there shouldn’t even be a special syntax for regular expressions, and instead they should be constructed from syntax elements already present in the programming language? If so, give examples of a syntax that might be used to construct such regular expressions.

  • Is the “jQuery programming style” a kind of Reactive programming?

    - by Peter Krauss
    jQuery is a Javascript library and framework, but when we are programming with jQuery into DOM problems/solutions, we can practice a style quite different of programming... We can read about jQuery at Wikipedia, The set of jQuery core features — DOM element selections, traversal and manipulation —, enabled by its selector engine (...), created a new "programming style", fusing algorithms and DOM-data-structures This question is similar to the "subquestion-3" of this question but not so generic. The focus here is about this new kind of "programming style"... So, the question: Is the "jQuery programming style in DOM context" a new paradign? Or it is more one example of reactive programming (not "cell-oriented" but "DOM-node oriented") or another one? We have no "standard taxonomy of paradigms", so, please, in your answer, indicate also your "best choice for Wikipedia Paradign". Example: if you understand that "jQuery programming DOM" is like "awk filtering data", your choice can be event-driven.

  • Is Agile the new micromanagement?

    - by Smith James
    Hi, This question has been cooking in my head for a while so I wanted to ask those who are following agile/scrum practices in their development environments. My company has finally ventured into incorporating agile practices and has started out with a team of 4 developers in an agile group on a trial basis. It has been 4 months with 3 iterations and they continue to do it without going fully agile for the rest of us. This is due to the fact that management's trust to meet business requirements with a quite a bit of ad hoc type request from high above. Recently, I talked to the developers who are part of this initiative; they tell me that it's not fun. They are not allowed to talk to other developers by their Scrum master and are not allowed to take any phone calls in the work area (which maybe fine to an extent). For example, if I want to talk to my friend for kicks who is in the agile team, I am not allowed without the approval of the Scrum master; who is sitting right next to the agile team. The idea of all this or the agile is to provide a complete vacuum for agile developers from any interruptions and to have them put in good 6+ productive hours. Well, guys, I am no agile guru but what I have read Yahoo agile rollout document and similar for other organizations, it gives me a feeling that agile is not cheap. It require resources and budget to instill agile into the teams and correct issue as they arrive to put them back on track. For starters, it requires training for developers and coaching for managers and etc, etc... The current Scrum master was a manager who took a couple days agile training class paid by the management is now leading this agile team. I have also heard in the meeting that agile manifesto doesn't dictate that agile is not set in stones and is customized differently for each company. Well, it all sounds good and reason. In conclusion, I always thought the agile was supposed to bring harmony in the development teams which results in happy developers. However, I am getting a very opposite feeling when talking to the developers in the agile team. They are unhappy that they cannot talk anything but work, sitting quietly all day just working, and they feel it's just another way for management to make them work more. Tell me please, if this is one of the examples of good practices used for the purpose of selfish advantage for more dollars? Or maybe, it's just us the developers like me and this agile team feels that they don't like to work in an environment where they only breathe work because they are at work. Thanks. Edit: It's a company in healthcare domain that has offices across US, but we're in Texas. It definitely feels like a cowboy style agile which makes me really not wanting to go for agile at all, esp at my current company. All of it has to do with the management being completely cheap. Cutting out expensive coffee for cheaper version, emphasis on savings and being productive while staying as lean as possible. My feeling is that someone in the management behind the door threw out this idea, that agile makes you produce more so we can show our bosses we're producing more with the same headcount. Or, maybe, it will allow us to reduce headcount if that's the case. EDITED: They are having their 5 min daily meeting. But not allowed to chat or talk with someone outside of their team. All focus is on work.

  • What is Python 20th and final guideline

    - by Eric
    Sometimes when my life needs some guiding light, I read the Zen of Python by Tim Peters and usually manage to get back on the tracks. Today was one of those days, so I checked it again. I've noticed that the "abstract" section says: Long time Pythoneer Tim Peters succinctly channels the BDFL's guiding principles for Python's design into 20 aphorisms, only 19 of which have been written down. What would be this last unwritten aphorism?

  • Does LearnDevNow offers a useful subscription for .NET related training : with video and text reference material?

    - by user766926
    Does LearnDevNow offers a useful subscription for .NET video and text reference training material or to learn .NET? I could not find a review of www.learnnowonline.com/learndevnow I've been doing research about places that offer .NET / ASP.NET / C# / LINQ / SQL / JQuery video training that provide excellent material for developers. Kind of like a Lynda.com for back end development. However, I have not find one place that offers quality material that is easily accessible for the user, and that is priced competitive. This is what I'm looking for: Online Video tutorials with free future updates (videos that can be accessed on any device ie: android portable devices, mac / ipad, linux machines) Printable courseware (ie PDFs so that you can take notes, print if necessary, and read in a tablet in case you don;t have internet access) labs, and easy to access code Pre/Post Assessments/Exams for each training to keep track of your progress and what you have learned/skills. (Appdev used to offer this but it was way too expensive (thousands for each training ie 1k for each. I paid about five thousand at Appdev, and now I regret that purchase), and after a few years/months the training became obsolete - outdated) I looked at learnnowonline.com/learndevnow but it seems that their courseware / text reference material can only be accessed online, and don't know if their videos work in all mobile devices, and browsers (Safari, Chrome, IE, Opera, Firefox) Also, it seems Appdev not longer exist and now is called " AppDev is now LearnNowPlus : www.learnnowonline.com/appdev That site not longer offers prices. I tried to find reviews but could not find any. Does anyone know, or can share a review about some of these type of online training service providers? I would appreciate your feedback on this, and if you can share your past experiences with their service or similar/better services that would even be better. Thanks.

  • What PC for programming? [on hold]

    - by James Jeffery
    I'm asking this here because I'm looking for some advice on a PC that will be suitable for my needs. I currently have mac's and have rarely used PC's apart from my Vaio laptop, which is on it's way out. I will be using the PC for C# and .NET development. I mainly develop desktop apps using a PC, but I will be doing some ASP.NET as I'm switching from PHP to ASP. The selection of PC's are on here: http://www.pcworld.co.uk/ I have £500, but if I can not spend all of that I'd be happy. I will be doing nothing on the computer apart from C# development (desktop and ASP). Any help would be much appreciated. My applications are not intensive. They are usually automation software for web scraping and marketing purposes.

  • using Generics in C# [closed]

    - by Uphaar Goyal
    I have started looking into using generics in C#. As an example what i have done is that I have an abstract class which implements generic methods. these generic methods take a sql query, a connection string and the Type T as parameters and then construct the data set, populate the object and return it back. This way each business object does not need to have a method to populate it with data or construct its data set. All we need to do is pass the type, the sql query and the connection string and these methods do the rest.I am providing the code sample here. I am just looking to discuss with people who might have a better solution to what i have done. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Data.SqlClient; using MWTWorkUnitMgmtLib.Business; using System.Collections.ObjectModel; using System.Reflection; namespace MWTWorkUnitMgmtLib.TableGateway { public abstract class TableGateway { public TableGateway() { } protected abstract string GetConnection(); protected abstract string GetTableName(); public DataSet GetDataSetFromSql(string connectionString, string sql) { DataSet ds = null; using (SqlConnection connection = new SqlConnection(connectionString)) using (SqlCommand command = connection.CreateCommand()) { command.CommandText = sql; connection.Open(); using (ds = new DataSet()) using (SqlDataAdapter adapter = new SqlDataAdapter(command)) { adapter.Fill(ds); } } return ds; } public static bool ContainsColumnName(DataRow dr, string columnName) { return dr.Table.Columns.Contains(columnName); } public DataTable GetDataTable(string connString, string sql) { DataSet ds = GetDataSetFromSql(connString, sql); DataTable dt = null; if (ds != null) { if (ds.Tables.Count 0) { dt = ds.Tables[0]; } } return dt; } public T Construct(DataRow dr, T t) where T : class, new() { Type t1 = t.GetType(); PropertyInfo[] properties = t1.GetProperties(); foreach (PropertyInfo property in properties) { if (ContainsColumnName(dr, property.Name) && (dr[property.Name] != null)) property.SetValue(t, dr[property.Name], null); } return t; } public T GetByID(string connString, string sql, T t) where T : class, new() { DataTable dt = GetDataTable(connString, sql); DataRow dr = dt.Rows[0]; return Construct(dr, t); } public List GetAll(string connString, string sql, T t) where T : class, new() { List collection = new List(); DataTable dt = GetDataTable(connString, sql); foreach (DataRow dr in dt.Rows) collection.Add(Construct(dr, t)); return collection; } } }

  • Automated unit testing, integration testing or acceptance testing

    - by bjarkef
    TDD and unit testing seems to be the big rave at the moment. But it is really that useful compared to other forms of automated testing? Intuitively I would guess that automated integration testing is way more useful than unit testing. In my experience the most bugs seems to be in the interaction between modules, and not so much the actual (usual limited) logic of each unit. Also regressions often happened because of changing interfaces between modules (and changed pre and post-conditions.) Am I misunderstanding something, or why are unit testing getting so much focus compared to integration testing? It is simply because it is assumed that integration testing is something you have, and unit testing is the next thing we need to learn to apply as developers? Or maybe unit testing simply yields the highest gain compared to the complexity of automating it? What are you experience with automated unit testing, automated integration testing, and automated acceptance testing, and in your experience what has yielded the highest ROI? and why? If you had to pick just one form of testing to be automated on your next project, which would it be? Thanks in advance.

  • Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project?

    - by Chris Barry
    There is some code which is GPL or LGPL that I am considering using for an iPhone project. If I took that code (JavaScript) and rewrote it in a different language for use on the iPhone would that be a legal issue? In theory the process that has happened is that I have gone through each line of the project, learnt what it is doing, and then reimplemented the ideas in a new language. To me it seems this is like learning how to implement something, but then reimplementing it separately from the original licence. Therefore you have only copied the algorithm, which arguably you could have learnt from somewhere else other than the original project. Does the licence cover the specific implementation or the algorithm as well? EDIT------ Really glad to see this topic create a good conversation. To give a bit more backing to the project, the code involved does some kind of audio analysis. I believe it is non-trivial to learn or implement, although I was prepared to embark on this task (I'm at the level where I can implement an FFT algorithm, and this was going to go beyond that.) It is a fairly low LOC script, so I didn't think it would be too hard to do a straight port. I really like the idea of rereleasing my port as well as using it in the application. I don't see any problem with that, and it would be a great way to give something back to the community. I was going to add a line about not wanting to discuss the moral issues, but I'm quite glad I didn't as it seems to have fired the debate a bit. I still feel a bit odd about using open source code to learn from. Does this mean that anything one learns from an open source project is not allowed to be used in a closed source project? And how long after or different does an implementation have to be to not be considered violation of the licence? Murky! EDIT 2 -------- Follow up question

  • Should universities put more emphasis on teaching their students about design patterns?

    - by gablin
    While I've heard about design patterns being mentioned in a few courses at uni, I know of only a single course which actually teaches design patterns. In almost all other areas (algorithms, parallelism, architecture, dynamic languages, paradigms, etc), there are several, often a basic course and an advanced course. Should universities put more emphasis about teaching their students about design patterns and provide more courses in design patters? Are lack of knowledge about design patterns common in just-graduated junior developers?

  • Python — Time complexity of built-in functions versus manually-built functions in finite fields

    - by stackuser
    Generally, I'm wondering about the advantages versus disadvantages of using the built-in arithmetic functions versus rolling your own in Python. Specifically, I'm taking in GF(2) finite field polynomials in string format, converting to base 2 values, performing arithmetic, then output back into polynomials as string format. So a small example of this is in multiplication: Rolling my own: def multiply(a,b): bitsa = reversed("{0:b}".format(a)) g = [(b<<i)*int(bit) for i,bit in enumerate(bitsa)] return reduce(lambda x,y: x+y,g) Versus the built-in: def multiply(a,b): # a,b are GF(2) polynomials in binary form .... return a*b #returns product of 2 polynomials in gf2 Currently, operations like multiplicative inverse (with for example 20 bit exponents) take a long time to run in my program as it's using all of Python's built-in mathematical operations like // floor division and % modulus, etc. as opposed to making my own division, remainder, etc. I'm wondering how much of a gain in efficiency and performance I can get by building these manually (as shown above). I realize the gains are dependent on how well the manual versions are built, that's not the question. I'd like to find out 'basically' how much advantage there is over the built-in's. So for instance, if multiplication (as in the example above) is well-suited for base 10 (decimal) arithmetic but has to jump through more hoops to change bases to binary and then even more hoops in operating (so it's lower efficiency), that's what I'm wondering. Like, I'm wondering if it's possible to bring the time down significantly by building them myself in ways that maybe some professionals here have already come across.
