You know, you should look at static linking.
These days, we all have HUGE hard drives, and a few extra megabytes (for carrying around libc and what not) is really not that big a deal anymore.
You could also try running your applications in chroot() jails and distributing those.

As long as there are the other web browsers (and I don't believe that they will die - which is good, because I don't want to see the internet in the hands of Google) it's just another web browser that you need to check compatibility with. |

You're right. dummynet works only in FreeBSD, it's actually built into the kernel.

Someone correct me if I'm wrong, but I don't think that AppSettings is typically meant to be used for these type of configuration settings.

I would expect tools that need this simply walk the tree in a depth-first manner and when they hit a leaf, just process it (e.g. compile) and remove it from the graph (or mark it as processed, and treat nodes with all leaves processed as leaves).
As long as it's a DAG, this simple stack-based walk should be trivial. |
Could I ask why you're not saving the user's settings in a database?
Generally, I save application settings that are changed very infrequently in the appSettings section (the default email address error logs are sent to, the number of minutes after which you are automatically logged out, etc.) The scope of this real... |
one thing I would look at doing is caching the appsettings on a read, then flushing the settings from the cache on the write which should minimize the amount of actual load the server has to deal with for processing the appSettings.
Also, if possible, look at breaking the appSettings up into [configSections][1] so y... |
