  • Is there a way to develop C#/.NET on Android devices?

    - by martani_net
    Hi, I want to run C# programs on my HTC Magic, I can find the mono app on the Android market but I have no clue on how to run C# using. The code is just for fun, I don't want official support and such. After coding Visual Basic on windows mobile, I really want to code C# on Android, whether directly using some sort of editor if exists, or compiling it on a PC then installing it on Android. If anyone knows a way to do such please let me know. Thank you

  • emacs local version control

    - by aaa
    hello. I am wondering if there is local version control/snapshots for emacs independent of VC? let me clarify: every time I save buffer, I would like to be able to keep track of changes of each save in session. I know I can do something similar with backup files, but they are not automated like VC and a somewhat cumbersome. I have searched Google, but did not find the solution. Perhaps my query string was not good. Thanks

  • Redirecting only if user asks for the root of the domain nad are froma particular country

    - by lphmedia
    Hi, I need a rule and condition to handle this scenario: User from US visits www.domain.com, domain.com, www.domain.com/ or domain.com/ this should be redirected to www.domain.com/usvisitor/ However, if a user from the US visits www.domain.com/anydirectory it will let them straight through without a redirection occurring. eg. RewriteEngine On RewriteBase / GeoIPEnable On GeoIPDBFile /var/share/GeoIP/GeoIP.dat RewriteEngine on RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^US$ RewriteCond %{HTTP_HOST} ^domain.com$ [L] RewriteRule ^/$ http://www.domain.com/usvisitor$1 [L] I know the RewriteConditons and rules are wrong - just can't get my head around it!

  • How can I show just the icon of the currently selected option?

    - by Paul Tomblin
    Is it possible to have a bunch of <select> dropdowns in html that only display a small (say 10 pixels wide) icon, but when you click it the drop down has a list with the icons beside a descriptive string. (Let's see if ASCII art works on SO): [X] | X - Disable | | v/ - Enable | | O - Ignore | +-------------+ [O] [v] [X] Can that be done in CSS? Or in jQuery?

  • Do you employ any tools for managing technical debt?

    - by Phil.Wheeler
    The site I work with on a day-to-day basis has its share of shortcomings and we often make design decisions to "get us by right now" with the intention of fixing those up later. I've found that making the time to actually go back and fix them, let alone remembering what the full list of to-do items is can be challenging at best. Can you recommend any tools, resources or tricks that help you effectively manage your technical debt?

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.
