java - When to use hash table? -

i have general question when should use hash table instead of avl trees. remembered lecturer saying if data size 2 10 or 2 20 , avl tree acceptable, because using hash table generate hashing operations etc. so wonder in practice, there general rule regarding data size tell when should choose hash table on avl trees? hash table first choice when dealing data size larger 2 20 ? hash tables 'wasteful' memory wise backing table larger number of entries. trees don't have problem have problem lookups (and other operations) log(n) operation. yes correct small data sets tree may better - depending on how care memory efficiency. there's no general rule data regarding data size - depends on specifics of implementations comparing , want optimize (memory or cpu). javadocs provide insight performance of implementations provided java: http://docs.oracle.com/javase/7/docs/api/java/util/treemap.html http://docs.oracle.com/javase/7/docs/api/java/util/hashmap.html

Why OpenCL doesn't have matrix data type? -

considering opencl kernels executed on same units shaders seem logical me opencl have same data types glsl, yet looking here: http://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/datatypes.html don't see matrix type. why that? also, mean if want multiply 4x4 matrices slower when using opencl glsl? actually, if @ link more closely there matrix data types in category of reserved datatypes: floatnxm, doublenxm. quite there implementation types in future releases of standard. have no idea why haven't done already. at point can use either array or image2d_t represent matrices. want take @ article what comes speed. doesn't mean opencl slower, quite likely. if manage write perfect matrix multiplication code 1 platform opencl, in other platform performance can quite poor. in opengl, manufacturers writing own matrix multiplication code should quite optimal each platform.

i've searched around found out getops receives 0 or 1 argument only, need make work, i need make script run this: ./script.sh -a string integer what write string , integer text file. i tried code: while getopts a:d opt case "$opt" in a) na1=$optarg eval "na2=${optind}" shift 2 ;; d) ./views.sh;; esac done if [ $isdef -eq 0 ] echo "$na1;$na2" >>pbdb.txt fi i can write string part text file integer keeps resulting "3". sample: ./script.sh -a power 0000 result inside textfile: power;3 any suggestions? just started learning bash scripting assuming bash tag accurate (you're not using /bin/sh), change eval "na2=${optind}" to use "indirect variable" na2=${!optind} with eval, you'd need eval na2=\$$optind that's uglier

i'm working socket operations , have coded basic interception proxy in python. works fine, hosts return 400 bad request responses. these requests not malformed though. here's one: get http://www.baltour.it/ http/1.1 host: www.baltour.it user-agent: mozilla/5.0 (x11; ubuntu; linux x86_64; rv:28.0) gecko/20100101 firefox/28.0 accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 accept-language: en-us,en;q=0.5 accept-encoding: gzip, deflate connection: keep-alive same request, raw: get http://www.baltour.it/ http/1.1\r\nhost: www.baltour.it\r\nuser-agent: mozilla/5.0 (x11; ubuntu; linux x86_64; rv:28.0) gecko/20100101 firefox/28.0\r\naccept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\naccept-language: en-us,en;q=0.5\r\naccept-encoding: gzip, deflate\r\nconnection: keep-alive\r\n\r\n the code use send request basic socket operation (though don't think problem lies there, works fine hosts) socket_client.send(request_raw)

mysql - How to make this JDBC code more portable? -

i have following piece of code: list<list<object>> batch = db.executeinsert("insert batches (batch_date,source,log_file,status) values (?, ?, ?, ?)", now, importzip.getabsolutepath(), logfile.getabsolutepath(), batchstatus.importing.tostring()) and returned data when run on mysql returns integer representing inserted id expected. when run under oracle returns non portable rowid object. have identity column, converted sequence represents id. however, there's not can rowid . i've checked code , i'm calling statement.getgeneratedkeys() thought whole point of making portable code. how can write in portable fashion without executing things select table rowid=? not portable. as found out, oracle returns rowid can - example - obtain id querying row. some databases return last generated id (which might not belong table, eg mysql afaik), databases return id column first column in resultset , others return all colum

Versioning of ActiveX COM DLL with Semantic Versioning but GUID per MAJOR.MINOR? -

long story short, i'm maintainer of visualbasic 6 project products activex com dll used internally ~50 other software packages have internal uses in organization. for last couple years have been following semantic versioning "major.minor.patch" each dll released , have been assigning unique guid per release. i.e. 1.1.1 , 1.1.2 have separate guids. it has worked ok, causes each of software packages require new release -- when none needed -- can reference new guid , recompile. wastes few dozen man hours due internal processes releases. my question is, "bad practice" maintain guid each minor release 1.1.1, 1.1.2, , 1.1.99 have same guid? better guid per major release instead? this cause references change when new major or minor release made reducing number of changes required software packages depend on it. lastly, if helps response, dlls named as: myactivexdll_vmajor.minor.patch.dll. with guid per minor switch myactivexdll_vmajor.minor.dll
