• Linqpad and StreamInsight

  Slightly before the announcement of StreamInsight being available for Linqpad I downloaded it from here.  I had seen Roman Schindlauer demonstrate it at Teched and it looked a really good tool to do some StreamInsight dev.   You will need .Net 4.0 and StreamInsight installed. Here’s what you need to do after downloading and installing Linqpad. Add a new connection   The next thing we need to do is install and enable the StreamInsight driver.  Choose to view more drivers.   Choose StreamInsight     Select the driver after install     I have chosen the Default Context.     And after all that I can finally get to writing my query.  This is a very simple query where I turn a collection (IEnumerable) into a PointStream.  After doing that I create 30 minute windows over the stream before outputting the count of events in each of those windows to the result window.     I have played with Linqpad only a little but I think it is going to be a really good tool to get ideas developed and quickly.  I have also enabled Autcompletion (paid £25) and I recommend it.

• How to manage security of these self hosted web apis, to ensure that the request coming for accessing data is authenticated?

  - by Husrat Mehmood

  Let's pretend I am going to work on an enterprise application. Say I have 11 modules in the application and I would have to develop Dashboards for every role in the organization for whom I are going to develop application. We Decided to use Asp.Net Web Api and return json data from our apis. We are going to include 11 Self hosted web apis projects in our application (one self hosted web api) for every module. All 11 modules are connected to one Sql server 2012 Database. Then once api is ready we would have to create Business Dashboards (Based upon roles in Organization). So Now my web api client is Asp.Net Mvc application.Asp.Net mvc will consume those web apis. Here is the part for whom all explanation is done. How should I manage Security of all 11 self hosted web apis? How should I only authenticated request is coming? If I authenticate user by login and password and then redirect user to appropriate Dashboard designed for the role that user have and load data by consuming web apis. How should I ensure that the request coming for accessing data is authenticated?

• How to break the "php is a bad language" paradigm? [closed]

  - by dukeofgaming

  PHP is not a bad language (or at least not as bad as some may suggest). I had teachers that didn't even know PHP was object oriented until I told them. I've had clients that immediately distrust us when we say we are PHP developers and question us for not using chic languages and frameworks such as Django or RoR, or "enterprise and solid" languages such as Java and ASP.NET. Facebook is built on PHP. There are plenty of solid projects that power the web like Joomla and Drupal that are used in the enterprise and governments. There are frameworks and libraries that have some of the best architectures I've seen across all languages (Symfony 2, Doctrine). PHP has the best documentation I've seen and a big community of professionals. PHP has advanced OO features such as reflection, interfaces, let alone that PHP now supports horizontal reuse natively and cleanly through traits. There are bad programmers and script kiddies that give PHP a bad reputation, but power the PHP community at the same time, and because it is so easy to get stuff done PHP you can often do things the wrong way, granted, but why blame the language?. Now, to boil this down to an actual answerable question: what would be a good and solid and short and sweet argument to avoid being frowned upon and stop prejudice in one fell swoop and defend your honor when you say you are a PHP developer?. (free cookie with teh whipped cream to those with empirical evidence of convincing someone —client or other— on the spot) P.S.: We use Symfony, and the code ends being beautiful and maintainable

• What to do when you're the interviewer and you don't like your job?

  - by emcb

  I'm in a sorta strange predicament, and I could use some advice. When I was interviewing for my current job, the job description I was given seemed pretty darn nice to me. Without going into the details, the job hasn't quite turned out the way it was advertised. The company is great and takes care of its employees, but for someone who cares about the code they write and the work they do, it's a bad environment - effectively, we operate between 0.5 and 1.0 on the Joel test, and due to political issues we're not going to move beyond that any time soon. Bitter? Maybe. OK...so I'm in the market for a new job. But that's not where my dilemma is. The problem that I see coming is that I will be participating in interviewing some candidates for a position on my team, and I'm not sure what to do. I've heard through the grapevine that we have some really solid, promising, fresh-out-of-college prospects coming in to interview, and I honestly dread the thought of somebody having their first experience of engineering in this department. So I'm wondering: what should I do if/when the interviewee asks me "Do you like your job?" (no) "What kind of projects would I be working on?" (mostly static HTML/CSS changes) Anything else that would elicit a negative answer if told truthfully Do I tell the truth, to give the candidate a real picture of the job? What if this scares them away, and what if it gets blamed on me? Do I fib or lie, saying we work on exciting projects with lots of flexibility, like the pitch my boss will give when the reality is quite different? Should I feel any kind of moral responsibility to let a promising young developer know that this isn't the job for them, or should I shut up and be loyal 100% to the company? Any approaches or advice is appreciated. I hope I don't come across as overly dramatic - I honestly struggle with this question.

• Web interface with FastCGI or with direct HTTP?

  - by Basile Starynkevitch

  Let's assume I want (for fun at start) to play with some new DSL (domain specific language) idea. And I really want its user[s] (probably only me at first) to interact thru a web interface. I'll probably implement it in C++ (probably using LLVM). Should I use an HTTP server library (like libonion or microhttpd) to talk directly HTTP or should I use FastCGI? In particular, I am noticing that several recent web frameworks (Opa, Ocsigen, ...) do not have any FastCGI interface but only HTTP one.... So my feeling is that FastCGI is really out of fashion.... Any opinions on that? Do you know recently started project using FastCGI ? (and what about SCGI?)

• I know fundamental programming. But how do I get started in game development now?

  - by Rohan Menon

  I'm a 20 year old programming student. I know fundamental programming in BASIC, C, C++ and JAVA. What I wanted to ask is, where do I go from here? Are there any books that the community can mention that will help me develop a game or at least learn game development? I've had a lot of ideas and really want to make some sort of prototype to see if I'm suited for the industry. I really don't mind learning any new languages but I need to know what I should begin with. A good book that will help with a little more understanding as I go up will be very helpful. Maybe a tutorial to develop some basic 2D games like a side-scroller, snake or pocket tanks in an easy to understand SDK? I know that to get some credit under your belt, you need to be able to make a few games on your own. Also, what platform should I start on? The PC, iOS or Android (as an introduction) for now. I don't want to get into high level game design just yet. Just something a bit basic to help out in future development. Anything pointing me in the right direction will be really really helpful. Edit: Also, I want to say that I'm looking towards this from a game designer's point of view more than a game programmer. I want suggestions on any SDKs or easy to use programs I can use to understand game design. Then delve deeper into the programming after that. Not as employment but as developing your own games (for now).

• How to deal with social login

  - by Matteo Pagliazzi

  In my new web app I'm going to allow social login through Twitter (maybe), Facebook and Google and I'm in search of the best way to do it. Actually I'm using Rails with Devise + Omniauth and this is the problem: Should I ask the user to choose a password so that he can login without a social network? Or maybe the user should be able to set a password if he want (for example when editing his account?) The second way seems the best one but since Twitter doesn't provide user email and google doesn't provide an username I'll probably have to ask the user for username/email when he log in so in that case I may also ask for the password... waht do you think?

• Should I be using WAI-ARIA in my HTML website builds?

  - by DBUK

  Should I be using WAI-ARIA in my website builds? Will it have any benefit? Is anyone adding 'role' to their code at the moment? The tab, link, checkbox and slider roles, plus many more, aren't available yet for HTML5. From looking at the list of what is available (see below), and what will be coming in the future, it looks like we might be applying roles to a huge amount of tags on our pages. Its not an issue especially if it brings benefit to users using readers etc Also, a side question, will search engines give any benefits to sites using WAI-ARIA? List of safe roles to use (I think) • role="article" • role="banner" • role="complementary" • role="contentinfo" • role="form" • role="heading" • role="main" • role="navigation" • role="search" Examples of usage: <header role="banner"></div>for a main header, banner only allowed once per page <header role="heading"></div>- for all headers after the main one <aside role="complementary"></aside> <form role="search"></form>

• How to Downgrade Packages on Ubuntu

  - by Chris Hoffman

  Ubuntu’s Update Manager keeps your packages at the latest version, but occasionally a new package version may not work properly. You can downgrade an installed package and lock it at a specific version to prevent it from being updated. This is particularly useful when you run into an updated package with a regression – a bug that prevents things from working properly.

  - by Chi-Ping Lee

  I want to install gcc on my computer. To do this, I ran the following command: sudo apt-get install build-essential As this runs, it connects (or tries to connect) to the server tw.archive.ubuntu.com. But the server is not working. How can I fix this and get gcc installed? Note: the Taiwan mirror is down as of 2012-06-01 0352. See thread here. This pastebin contains the text of /etc/apt/sources.list, after changing from tw.archive.ubuntu.com to the main server.

• Building a website, want to use java

  - by Robb

  I'd like to make a simple-ish website that is essentially a small game. Key strokes are to be processed and sent to a server (already acquired and should support SQL and JSP, I believe) which then translate to a location and written to the DB. SQL queries are to be used to retrieve these locations and written to other clients connected to the website. Their page is to be updated with these locations. I have working knowledge of Java, jQuery/Ajax, SQL and JavaScript but I'm unfamiliar with JSP and how everything hooks up. I'm aware of the MVC paradigm as well. For my little game idea, would these technologies work? Am I over thinking this and can make it much easier to implement? What might be a good tutorial or example to study?

• How would I go about measuring the impact an article has on the internet?

  - by Jimbo Mombasa

  For an application of mine, I analyze the sentiment of articles, using NLTK, to display sentiment trends. But right now all articles weigh the same amount. This does not show a very accurate picture because some articles have a higher impact on the internet than others. For example, a blog post from some unknown blog should not weigh the same amount as an article from the New York Times. How can I determine their impact?

• How do you overcome your own coding biases when handed legacy code?

  - by Bryan M.

  As programmers, we often take incredible pride in our skills and hold very strong opinions about what is 'good' code and 'bad' code. At any given point in our careers, we've probably had some legacy system dropped in our laps, and thought 'My god, this code sucks!' because it didn't fit into our notion of what good code should be, despite the fact that it may have well been perfectly functional, maintainable code. How do you prepare yourself mentally when trying to get your head around another programmer's work?

• Stupid simple music player?

  Here's what I want: I have a folder with MP3 files. I would like to play all the files in the folder, alphabetically. And I need a way to pause, skip to next file, and that's pretty much it. I don't want to use my music player to organize my music library, I don't need connection to network services, and I don't even need ID3 support. On Windows, WinAmp 2 did what I wanted. What's my best option on Ubuntu?

• Creating a Website Without a Framework [closed]

  - by James Jeffery

  I've been using PHP Frameworks for so long that I've actually forgot the "best practices" for create websites without one. Usually I will use Symfony, or more recently I've been using Laravel. A client wants a very simple website, but with certain parts of it dynamic. Due to the nature of the site using Wordpress, or a Framework, is out of the question. I'm a sucker for priding myself on my code, but I feel like I'm asking such a basic question that it's killing me to ask. But, what are the best practices for creating websites without a Framework? I like to live by the K.I.S.S (Keep It Simple Stupid!) method of thinking. So, my idea was to just create the .php pages that are required, do any page processing or database interaction on that page, then have the HTML below the closing PHP tag. I would have any helpers/functions in a functions.php file. This is what I remember doing way before I was using Frameworks, and to me it seems like a very old school way of doing things. I've not created a site without a Framework for literally 2+ years, so I've lost my way with the basics. Any advice would be greatly appreciated.

• How could a human factors degree help a computer scientist?

  - by Bob Dole

  I'm wrapping up a masters in CS and already have half the credit hours needed for a degree in Human Factors. I just recently discovered how useful understanding about cognition can help someone that creates user interfaces and am thirsty for more knowledge in the area. For me, it seems that having both a masters in Human Factors and CS would be very marketable but would there be jobs out there that would allow me to apply both? Meaning what I would really like to do is take the requirements for some application, apply different Human Factors theories( GOMS, CE+ ) to developing the interface, maybe do cognitive walk through with users to optimize the UI, then develop the application. Do jobs out there exist like this? The reason I ask, is because I'm wondering if most places just want you to be either a Human Factors Expert or a Developer but not both.

• Using which technique does facebook and pininterest show images?

  - by manish

  If anybody has ever noticed that when you open a image in Facebook something like this happens:- suppose you are at your homepage on Facebook:- the URL is https://www.facebook.com/ now if you open a image it gets opened in new modal like window and URL changes to:- https://www.facebook.com/photo.php?fbid=10151125374887397&set=a.338008237396.161268.36922302396&type=1&theater As far as I know in any common case a modal overlay would have kept the url in the address bar the same , My question is how does facebook / pintrest achieve this behaviour of not re-loading the whole page but still achieving the change in the address bar. Is there any jquery or javascript plugin for this?

• .aspx websites: Is it built using web forms?

  - by Lazeera

  I visit many website which I think is built using ASP.NET web forms because of the extension (.aspx). When I view source of these website I see at least one or two something like: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> or wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... However, yesterday I visited two sites on is the 'ASP.NET forums - http://forums.asp.net' and the other is 'POF'. The extension of these sites is still (.aspx) but when I view the source of these site I could not find any <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> nor wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... Now, I would like to know how those sites use ASP.NET Web Forms and their final HTML output is still clean?
