• Visual Studio 2013 - Express for Web vs Professional [duplicate]

  - by TimS

  This question already has an answer here: Visual Studio 2012 - Express vs Professional 2 answers What are the main differences and limitations between Visual Studio 2013 Express and Visual Studio 2013 Professional? I'm specifically interested in information related to the Web edition. I need to be able to develop ASP.Net applications, Windows Services and console applications - not Desktop or Phone apps. Microsoft seems to hide this information well and I can only seem to find information relating to 2012 products and earlier.

• Should I use C style in C++?

  - by c.hughes

  As I've been developing my position on how software should be developed at the company I work for, I've come to a certain conclusion that I'm not entirely sure of. It seems to me that if you are programming in C++, you should not use C style anything if it can be helped and you don't absolutely need the performance improvement. This way people are kept from doing things like pointer arithmetic or creating resources with new without any RAII, etc. If this idea was enforced, seeing a char* would possibly be a thing of the past. I'm wondering if this is a conclusion others have made? Or am I being too puritanical about this?

• Caching large amount of ajax returned objects

  - by ofcapl

  I'm building an application which fetches large amount of items with ajax requests via other application API. It returns me 6k - 30k js objects which are used multiple times across various application views (sorting, filtering etc.). I would like to avoid querying API every time for such big list so I decided to cache this data somehow. I was thinking about various solutions: saving it to localstorage, using some caching library (e.g. locachejs), storing in js var. I'm not an expert so I would like to hear Your suggestions about each (or one of these) solution, about its pros and cons. Every help will be very appreciated.

• 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.

• 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 ?

• Questioning pythonic type checking

  - by Pace

  I've seen countless times the following approach suggested for "taking in a collection of objects and doing X if X is a Y and ignoring the object otherwise" def quackAllDucks(ducks): for duck in ducks: try: duck.quack("QUACK") except AttributeError: #Not a duck, can't quack, don't worry about it pass The alternative implementation below always gets flak for the performance hit caused by type checking def quackAllDucks(ducks): for duck in ducks: if hasattr(duck,"quack"): duck.quack("QUACK") However, it seems to me that in 99% of scenarios you would want to use the second solution because of the following: If the user gets the parameters wrong then they will not be treated like a duck and there will be no indication. A lot of time will be wasted debugging why there is no quacking going on until the user finally realizes his silly mistake. The second solution would throw a stack trace as soon the user tried to quack. If the user has any bugs in their quack() method which cause an AttributeError then those bugs will be silently swallowed. Once again time will be wasted digging for the bug when the second solution would simply give a stack trace showing the immediate issue. In fact, it seems to me that the only time you would ever want to use the first method is when: The block of code in question is in an extremely performance critical section of your application. Following the principal of "avoid premature optimization" you would only realize this of course, after you had implemented the safer approach and found it to be a bottleneck. There are many types of quacking objects out there and you are only interested in quacking objects that quack with a very specific set of arguments (this seems to be a very rare case to me). Given this, why is it that so many people prefer the first approach over the second approach? What is it that I am missing? Also, I realize there are other solutions (such as using abcs) but these are the two solutions I seem to see most often for the basic case.

• 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.

• I'd like to learn how to do mobile development - which competitions can I join to help me learn?

  - by Oscar

  I want to start learning mobile device development, but I am someone that gets much more motivated when there is some goal to reach. Because of that, I would like to join a competition. I know about Microsoft Imagine Cup, which is a very nice competition. Are there any another mobile development competition with a deadline in the next 6~8 months? I have been googling for them, but I could not find any, maybe someone knows about something that I couldn't find.

• What should I quote for a project I hope to get a job at the end of?

  - by thesunneversets

  Long story short: I applied for a (CakePHP, MySQL, etc) development job in London, UK. I grew up in Britain but am currently based quite a few thousand miles away in Canada, so I wasn't really expecting success. But quite a few emails and phone interviews later it seems that they really like me. At least to a point. Because such a major relocation would be a horrible thing to go wrong, they've sensibly suggested a trial run of getting me to build a website at a distance. I have the spec for this and it's quite a substantial amount of work. My problem is that I now need to suggest both a fee and a timescale for the job, and I haven't got any significant experience of working as a contractor. Looking at the spec, which is 1500 words of many concisely stated features, some fairly trivial and some moderately involved, I can easily imagine there being 2 weeks of intensive work there. (If everything went really well it might be closer to one week, but even though I want to impress, I definitely don't want to fall into the inexperienced-contractor trap of massively underestimating the amount of time a project will run to.) As an extra complication, there is no expectation that I should give up my day job to get this trial project done, so the hours will have to be clawed from evenings and weekends. I don't want to overcommit to a quick delivery date, only to find myself swiftly burning out due to an unrealistic workload. So, any advice for me? My main question is, what is a realistic hourly figure to demand of a stable but not excessively wealthy London-based company in the current market, bearing in mind that I'd like them to hire me afterwards? But any more general recommendations based on my circumstances above would be much appreciated too. Many thanks!

• 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.

• What about introduction to programming with C# via LINQPad?

  - by Gulshan

  From different questions/answers/articles in this and some other sites, I got the idea that the introductory language for programming should be- High level Less verbose C# is one of the heavily used high level languages being used these days. It's also multi-paradigm and descendant of C, the lingua-franca of all programming languages. So, I think it has the potential to be the introductory programming language. But I felt it's a bit verbose for the novice learners. Then LINQPad came into my mind. With LINQPad, someone can start with C# without it's verbosity. Because you can just run one statement or few statements or a standalone function with LINQPad. Again you can run a full source file also. Another thing it provide is- using SQL. So, it can be used for learning SQL too. And not to mention, it's free. So, what you guys think about the idea of introducing programming with C# via LINQPad? Any thing to watch out? Any suggestion?

• What should you leave behind for your successors?

  - by SnOrfus

  Assume that you're a sole developer leaving a job. What kind of information/material, outside of the code itself, should you create and leave behind for your replacement? An obvious answer is "whatever you would want at a new job" for sure, but it's been a while since I started a new job, and I forget what the most important things that I needed were back then. I'm thinking: accounts/passwords location of equpiment What else?

• Can I trust the Basic schedule equation?

  - by Steve Campbell

  I've been reading Steve McConnell's demystifying the black art of estimating book, and he gives an equation for estimating nominal schedule based on Person-months of effort: ScheduleInMonths = 3.0 x EffortInMonths ^ (1/3) Per the book, this is very accurate (within 25%), although the 3.0 factor above varies depending on your organization (typically between 2 and 4). It is supposedly easy to use historical projects in your organization to derive an appropriate factor for your use. I am trying to reconcile the equation against Agile methods, using 2-6 week cycles which are often mini-projects that have a working deliverable at the end. If I have a team of 5 developers over 4 weeks (1 month), then EffortInMonths = 5 Person Months. The algorithm then outputs a schedule of 3.0 x 5^(1/3) = 5 months. 5 months is much more than 25% different than 1 month. If I lower the 3.0 factor to 0.6, then the algorthim works (outputs a schedule of approx 1 month). The lowest possible factor mentioned in the book through is 2.0. Whats going on here? I want to trust this equation for estimating a "traditional" non-agile project, but I cannot trust it when it does not reconcile with my (agile) experience. Can someone help me understand?

• Why don’t UI frameworks use generics?

  - by romkyns

  One way of looking at type safety is that it adds automatic tests all over your code that stop some things breaking in some ways. One of the tools that helps this in .NET is generics. However, both WinForms and WPF are generics-free. There is no ListBox<T> control, for example, which could only show items of the specified type. Such controls invariably operate on object instead. Why are generics and not popular with UI framework developers?

• Tester that doesn't test

  - by George

  What should I do about a tester that does not test? We have a complicated dry run scenario, that takes a lot of time to execute. Mostly this tester will execute it's tests in very slow way...checking emails, internet, etc. He reports just a few bugs, but! Whenever the official dry-run begins (these are logged with testlink) the tester starts to open new bugs that where not discovered before. Is he not doing his job correctly? Or am I just overlooking how tests work? I'm not his supervisor, but he is testing code that I wrote.

• Clarification about Event Producer in StreamInsight

  - by sandy

  I need a small clarification about streamInsight, I know by doc's that StreamInsight can handle multiple concurrent Events. But will the event producer be a separate function, for ex: I need to watch a folder for new Files becoz all my sensors il write readings every day in a new file in particular drive. Method 1: FileSystemWatcher: These is the traditional approach where we write a service using FileSystemWatcher to watch a folder for new files,etc.. Upon receiving event from FileSystemWatcher il perform some operations on these files. How to do these using streamInsight??? I came know that using IObservable i can push events to StreamInsight. But is there anything to watch folder is sreamInsight like FileSystemWatcher. OR In order to raise events to streamInsight do we need to use FileSystemWacther? Any suggestion regarding these is highly appreciated. Thank in Advance

• How does one improve one's problem-solving ability?

  - by gcc

  How can one improve one's problem-solving ability? Everyone says same thing: "a real programmer knows how to handle real problem." But they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "use complex/known library instead of using your own." In other words, I want your personal experience, book recommendation, webpage on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

• What do you do when a client requires Rich Text Editing on their website?

  - by George Stocker

  As we all know by now, XSS attacks are dangerous and really easy to pull off. Various frameworks make it easy to encode HTML, like ASP.NET MVC does: <%= Html.Encode("string"); %> But what happens when your client requires that they be able to upload their content directly from a Microsoft Word document? Here's the scenario: People can copy and paste content from Microsoft word into a WYSIWYG editor (in this case tinyMCE), and then that information is posted to a web page. The website is public, but only members of that organization will have access to post information to a webpage. What is the best way to handle this requirement? Currently there is no checking done on what the client posts (since only 'trusted' users can post), but I'm not particularly happy with that and would like to lock it down further in case an account is hacked. The platform in question is ASP.NET MVC. The only conceptual method that I'm aware of that meets these requirements is to whitelist HTML tags and let those pass through. Is there another way? If not, is the best way to let them store it in the Database in any form, but only display it properly encoded and stripped of bad tags? NB: The questions differ in that he only assumes there's one way. I'm also asking the following questions: 1. Is there a better way that doesn't rely on HTML Whitelists? 2. Is there a better way that relies on a different view engine? 3. Is there a WYSIWYG editor that includes the ability to whitelist on the fly? 4. Should I even worry about this since it will only be for 'private posting' (Much in the same way that a private blog allows HTML From the author, but since only he can post, it's not an issue)? Edit #2: If suggesting a WYSIWYG editor, it must be free (as in speech, or as in beer). Update: All of the suggestions thus far revolve around a specific Rich Text Editor to use: Only provide an editor as a suggestion if it allows for sanitization of HTML tags; and it fulfills the requirement of accepting pasted documents from a WYSIWYG Editor like Microsoft Word. There are three methods that I know of: 1. Not allow HTML. 2. Allow HTML, but sanitize it 3. Find a Rich Text Editor that sanitizes and allows HTML. The previous questions remain (1-4 above).

• How could RDBMSes be considered a fad?

  - by StuperUser

  Completing my Computing A-level in 2003 and getting a degree in Computing in 2007, and learning my trade in a company with a lot of SQL usage, I was brought up on the idea of Relational Databases being used for storage. So, despite being relatively new to development, I was taken-aback to read a comment (on Is LinqPad site quote "Tired of querying in antiquated SQL?" accurate? ) that said: [Some devs] despise [SQL] and think that it and RDBMS are a fad Obviously, a competent dev will use the right tool for the right job and won't create a relational database when e.g. flat file or another solution for storage is appropriate, but RDBMs are useful in a massive number of circumstances, so how could they be considered a fad?

• How can Swift be so much faster than Objective-C?

  - by Yellow

  Apple launched its new programming language Swift today. In the presentation, they made some performance comparisons between Objective-C and Python. The following is a picture of one of their slides, of a comparison of those three languages performing some complex object sort: There was an even more incredible graph about a performance comparison working on some encryption algorithm. Obviously this is a marketing talk, and they didn't go into detail on how this was implemented in each. I leaves me wondering though: how can a new programming language be so much faster? In this example, surely you just have a bad Objective-C compiler or you're doing something in a less efficient way? How else would you explain a 40% performance increase? I understand that garbage collection/automated reference control might produce some additional overhead, but this much?

• 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...

• "My stuff" vs. "Your stuff" in UI texts

  - by JD Isaacks

  When refering to a users stuff should you use My or Your, for example: My Cart | My Account | My Wishlist Or Your Cart | Your Account | Your Wishlist I found this article that argues for the use of your. It says flikr does this. It also says MySpace and MyYahoo are wrong. I also noticed today that Amazon uses the term Your. However, I have heard they are the masters at testing variations and finding the best one, so what you see on their site might be the best variation, or simply something they are currently testing. I personally like the way my looks better, but thats just my opinion. What do you think? What will hever the better impact on customers? Does it really even matter?

• Best practices for logging user actions in production

  - by anthonypliu

  I was planning on logging a lot of different stuff in my production environment, things like when a user: Logs In, Logs Off Change Profile Edit Account settings Change password ... etc Is this a good practice to do on a production enviornment? Also what is a good way to log all this. I am currently using the following code block to log to: public void LogMessageToFile(string msg) { System.IO.StreamWriter sw = System.IO.File.AppendText( GetTempPath() + @"MyLogFile.txt"); try { string logLine = System.String.Format( "{0:G}: {1}.", System.DateTime.Now, msg); sw.WriteLine(logLine); } finally { sw.Close(); } } Will this be ok for production? My application is very new so im not expecting millions of users right away or anything, looking for the best practices to keeping track of actions on a website or if its even best practice to.
