i have linq query selects list of teamids , team names populate drop down list. query looks this: var teams = db.teams.where(t => t.isactive) .select(t => new {t.teamid, t.teamname}); however, want result set in form of 2d string array, since that's function populates ddls requires. know can use loop , build array, i'd prefer it, if possible in 1 step. is there similar this? string[][] teams = db.teams.where(t => t.isactive) .select(t => new {t.teamid, t.teamname}) .to2darray(); kind of: string[][] teams = db.teams.where(t => t.isactive).select(t => new[] {t.teamid, t.teamname}).toarray();

this query: with x (select '<promotions> <promotion promotion-id="old-promotion"> <enabled-flag>true</enabled-flag> <searchable-flag>false</searchable-flag> </promotion> <promotion promotion-id="new-promotion"> <enabled-flag>false</enabled-flag> <searchable-flag>false</searchable-flag> <exclusivity>no</exclusivity> <price>100</price> <price>200</price> <price>300</price> </promotion> </promotions>'::xml t ) select xpath('/promotions/promotion/@promotion-id', t) promotion_id, xpath('/promotions/promotion/enabled-flag/text()', t) enabled_flag, xpath('/promotions/promotion/exclusivity/text()', t) exclusivity, xpath('/promotions/promotion/price/text()', t) price x for elements exclusivity , price

i've read conflicting things on this: in asp.net (and mvc), request.url.host return host header request? i've seen code checks request.headers["host"] first, degrades using request.url.host if there problem, don't understand why needed if identical. they're not identical. httprequest.headers["host"] gives direct access client-to-server http header. httprequest.url rebuilt asp.net , use incoming request's host: header default, there internal setting usehostheaderforrequesturl , if set false asp.net use httprequest.headers["server_name"] instead, under circumstances uses value of "127.0.0.1" instead.

i don't understand how read general syntax. want request url through our proxy , requires specific host, port, username, , password. don't know how figure out protocol is. want curl through proxy. based on helpfile below, guess line should be: curl -x [whatever-my-protocol-is://]my-host-which-i-know[:my-port-which-i-know] -u my-username-which-i-know[:my-pass-which-i-know] http://www.google.com is right? how figure out protocol? relevant info man: -x, --proxy [protocol://]host[:port] use proxy on given port --proxy-anyauth pick "any" proxy authentication method (h) --proxy-basic use basic authentication on proxy (h) --proxy-digest use digest authentication on proxy (h) --proxy-negotiate use negotiate authentication on proxy (h) --proxy-ntlm use ntlm authentication on proxy (h) -u, --proxy-user user[:password] proxy user , password --proxy1.0 host[:port] use http/1.0 proxy on given port solved: ignore "["

i'm planning use python build couple of programs used services, run php code later on. in terms of performance, faster, compile python code binary file using cx_freeze or run python interpreter each time run program? deployment environment: os: arch linux arm hardware: raspberry pi [700mhz armv6 cpu, 256mb ram, sd card filesystem] python interpreter: python2.7 app calls frequency: high you need test it, because there's no single right answer. cx_freeze wrap bytecode executable, vs. interpreter reading cached .pyc on disk. in theory packaged executable quicker because it's reading fewer files, on other hand interpreter quicker because in disk cache. there's little choose, , whatever difference is, it's not down "compiled" vs. "interpreted".

i have ssrs report displays summary table of records. after click on 1 of records, goes individual report of record has multiple lines on configurable. now have add column in summary table report displays line numbers checked on individual report. there scalar function in database used determine whether line checked based on guid of record , internal label string given line. there stored procedure gets line number displayed on report database. so getting line numbers display on summary report, planning on calling udf each record in stored procedure gets records summary report. there problem in case since cannot call stored procedure function. need call stored procedure gets line number display each record, since line numbers can be unique different records. i thought of converting function stored procedure mean need call each record require while loop or cursor. not sure whether loop best possible solution case. cannot change stored procedure gets line numbers function si

i have strong background in numeric compuation using fortran , parallelization openmp, found easy enough use on many problems. switched python since more fun (at least me) develop with, parallelization nummeric tasks seem more tedious openmp. i'm interested in loading large (tens of gb) data sets to main memory , manipulate in parallel while containing single copy of data in main memory (shared data). started use python module multiprocessing , came generic example: #test cases #python parallel_python_example.py 1000 1000 #python parallel_python_example.py 10000 50 import sys import numpy np import time import multiprocessing import operator n_dim = int(sys.argv[1]) n_vec = int(sys.argv[2]) #class contains large dataset , computationally heavy routine class compute: def __init__(self,n_dim,n_vec): self.large_matrix=np.random.rand(n_dim,n_dim)#define large random matrix self.many_vectors=np.random.rand(n_vec,n_dim)#define many random vectors organize

how reallocate buffer buf , in method have used below? [filedata getbytes: buf length: 1024]; in code have declared buf char n storing 1050 characters in char buf[1050] . you can't "reallocate" buffer on stack, size of defined @ compile time. want use dynamic allocation instead: #define mybuflen 1024 char *buf = (char *)malloc(mybuflen); [filedata getbytes:buf length:mybuflen]; and don't forget free() when you're done it, else leak memory pretty quickly: free(buf);
