virtualization - virtual clock speed throttling on linux -


throttling @ execution , display speed of particular process, example, game, flash game, or opengl game. want able slow down 20% or 0.5%. not possible on host space in linux.

but linux supports 2 kernel-level virtualisation environments: kvm , lxc.

question: possible provide fake system clock virtual lxc or kvm machine flash game running in guest not run faster set run?

some choices:

  1. qemu brake patch (will require work apply no doubt.)
  2. bochs has ips=nnnn define cpu "instructions per second".
  3. cpulimit tool limiting cpu usage of process (does not require virtualization.)

update: want this: https://superuser.com/questions/454534/how-can-i-slow-down-the-framerate-of-a-flash-game

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
