  • Start Line with (New... in VB.net

    - by pedro_cesar
    Hello; Why can't I start a line using a parenthesis followed by the keyword new?? For example: (New <custom_obj>).foo(var) In that case is obvious that I'm trying to avoid creating a named instance of the the <custom_obj> because I know that I'll only be using it at that sentence. Note that actually creating a named instance is not a problem for me... I just wanna know the reason why this is not possible.

  • Windows 7 64-bit on brand new HP Pavilion

    - by Bill K
    Is anyone else experiencing Chrome extensions disappearing upon closing the browser? I do have the Click and Clean extension installed, and I'm wondering whether that is uninstalling my extensions somehow when it deletes browsing history. Thanks!

  • technology for new webproject?

    - by elCapitano
    Hi there, i am planing to set up a new webproject which has to use a database and a model which can be presented in a browser. I looked at a lot of technologies (JSF, PHP, ..) but i could not find a free and easy framework/technology for me (in the end i prefered asp.net, but this is not free). What can you recommend me for a new webproject from scratch?

  • Automate the process of looking for CVE (new vulnerabilities) related to our infrastructure

    - by skinp
    Is there any service available where you simply list the services, programs and versions you use, and when some CVE comes out about it, you automatically get alerted? Also, is there any other place to look for this kind of information. Do some people release security vulnerabilities to other places than CVE? So in general, how do you guys keep up to date with what might be vulnerable in your infrastructure? Edit: Since I've been asked, we are a Unix shop with mostly Red Hat and some HP-UX. I would still prefer a high level solution which are OS independent. What happens if we use software versions which are not in the official repositories of Red Hat/HP/... or simply not supported by them.

  • Language Prejudices

    - by paranoid_pedlar
    I've been researching programming languages, in hopes of learning to program. Since I've heard a lot of good things about Ruby, I went ahead and purchased The Pragmatic guide to Ruby. I understand that there is a lot of hype about Ruby on Rails. Because ruby lets you program scripts, applications, and internet helped me to decide on learning Ruby vs other languages. Today I watched a talk about google go, and it's really caught my attention. Coincidently I stumbled on a talk about jruby. I've been under the impression that java applications are bloated an slow. However the speaker made a point of what is wrong with Ruby, and how Jruby diagnosed Ruby's shortcomings. All that said. I would like to hear peoples opinions on Jruby vs Ruby, and if Ruby is working on fixing these "short comings". Also, how do you, the programming community feel about "go" and if I'm making a mistake learning Ruby instead of go, or Jruby. Appreciate your advice and opinions Thanks,

  • Infrastructure for high transactional system (language & hosting suggestion help)

    - by RPS
    Some of our friends (University students) are trying to develop a twitter type application, I want to plan for at least 1000 transactions per second (I know it's wishful thinking) for initial launch. This involves several people connecting and getting updates and posting (text + images) to site. In the back end db will server the data and also calculates rankings of what to push to user based on complex algorithm on the fly real-time. Our group is familiar with Java and Tomcat/MySQL. We can also easily learn/code in PHP/MySQL. What is the best suited platform for our purpose ? Though Java seem to be easy to implement for us I am afraid that hosting will be a bit difficult. I could find cloud based php hosting services (like rackspace cloudsites) at reasonable cost. Amazon EC2 is a bit over our heads to manage on day-to-day. Also any recommendation on hosting ? (PHP or Java) We don't have millions in seed money but about $20K to start with. Any advice on above or any thing in general approach is much appreciated.
