• How many copies of files are needed by video server?

  - by Trilok

  A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?

• Why no DatePicker.setDateChangedListener() method

  - by OceanBlue

  Since most widgets have a standard method of setting a listener, setOnXXXListener(), just wondering why there is no setDateChangedListener() method for DatePicker? I know init(int, int, int, OnDateChangedListener) can be used for the same purpose, but surely there must be some reason why Google decided not to use the standard method here. I went through the API docs and couldn't find the reason. Would one of the gurus here know the answer to this?

• how to determine base of a number?

  - by evil.coder

  Given a integer number and its reresentation in some arbitrary number system. The purpose is to find the base of the number system. For example, number is 10 and representation is 000010, then the base should be 10. Another example: number 21 representation is 0010101 then base is 2. One more example is: number is 6 and representation os 10100 then base is sqrt(2). Does anyone have any idea how to solve such problem?

• Mercurial repo inside a repo

  - by AkiRoss

  Is it possible to create a mercurial repository inside an existing mercurial repository? The idea is to handle subdirectories of a repository as different repositories, how do you do that? I'm not talking about subrepos (at least, if I understood the purpose of subrepos...), but if this is how subrepos do exist for, I got it wrong and I'll try to get it right :) Thanks ~Aki

• Convert UTF-16 to UTF-8 under Windows and Linux, in C

  - by DooriBar

  I was wondering if there is a recommended 'cross' Windows and Linux method for the purpose of converting strings from UTF-16LE to UTF-8? or one should use different methods for each environment? I've managed to google few references to 'iconv' , but for somreason I can't find samples of basic conversions, such as - converting a wchar_t UTF-16 to UTF-8. Anybody can recommend a method that would be 'cross', and if you know of references or a guide with samples, would very appreciate it. Thanks, Doori Bar
