i using jqplot show candlestick chart , data xml . retrieve data xml , put array , jqplot creates candlestick chart that. xml file contains lots of data in chart values overlapping (with fixed width). is possible make graph of lets 10% of data , place scrollbar , on every tick of scrollbar rebuild graph next data or there exists such functionality of scrolling of graph/chart in jqplot . please me resolve this. its better load xml @ once, not give data @ once jqplot chart. make sure passing part of data jqplot . once assign data chart go scrolling of data using jquery or scroller code. whenever scroll on try refresh or regenrate chart selected data.

recently reading partitioning code .net assemblies , stumbled upon nice suggestion this post : "reduce number of .net assemblies strict minimum". i couldn't agree more! , 1 of reasons see often, people want isolate piece of code, make types/methods internal , put them separate project. there many other reasons (valid , not) splitting code several assemblies, if want isolate components/apis while still having them located in 1 library, how can that? namespace myassembly.someapiinternals { //methods class should not //be used outside myassembly.someapiinternals internal class foo { internal void boo() { } } } namespace myassembly.anotherpart { public class program { public void test() { var foo = myassembly.someapiinternals.foo(); foo.boo(); //ok, not compiler error red flag @ least } } } how can 1 restrict t...

i need analyze sound written in .wav file. need transform file set of numbers (arrays, example). think need use wave package. however, not know how works. example did following: import wave w = wave.open('/usr/share/sounds/ekiga/voicemail.wav', 'r') in range(w.getnframes()): frame = w.readframes(i) print frame as result of code expected see sound pressure function of time. in contrast see lot of strange, mysterious symbols (which not hexadecimal numbers). can anybody, pleas, me that? per the sources , scipy.io.wavfile.read(somefile) returns tuple of 2 items: first sampling rate in samples per second, second numpy array data read file. looks pretty easy use!

hey guys, separating xhtml php putting xhtml separate file , using php's include() function within php script. this works fine, however, users still able access .html file directly if know address. can't it, rather not show. i've seen scripts in past use form of referrer check, add basic ( notice said 'basic' ) restrictions prevent being viewed accessing directly? thanks! clarification : forgot mention want within php, no web-server configuration ( moving files out of document-root, configuring web-server disallow access, etc. ). think logical choice here use define() constant check, that's indeed i've seen in other scripts had forgotten, outlined in post. realize not best solution, given html file can access of no particular value, define() constant should suffice. appreciate responses! if place files (like index.php) in /something/public_html/ want move files /something/ . way users cannot access files. the /public_html/ called...

i going through basic stuff learning c. came upon question multiply number 7 without using * operator. it's this (x << 3) - x; now know basic bit manipulation operations, can't how multiply number other odd number without using * operator? there general algorithm this? think how multiply in decimal using pencil , paper: 12 x 26 ---- 72 24 ---- 312 what multiplication in binary? 0111 x 0101 ------- 0111 0000 0111 ------- 100011 notice anything? unlike multiplication in decimal, need memorize "times table," when multiplying in binary, multiplying 1 of terms either 0 or 1 before writing down in list addends. there's no times table needed. if digit of second term 1, add in first term. if it's 0, don't. note how addends progressively shifted on left. if you're unsure of this, few binary multiplications on paper. when you're done, convert result decimal , see if it's correct. after you...

sites twitter , facebook scale hundreds of thousands of users. of architectural overviews available online talks , slideshows. however, question more oriented towards messaging middleware/layer these sites use. understand different different sites - there common characteristics when using messaging technologies (e.g. jms) on highly scaled sites? more specifically, there use cases cannot handled traditional messaging solutions? twitter switched scala middleware , got huge performance boost. high-scalability best authority on topic of scaling web applications.
