i'm downloading 2 datasets 2 different databases need joined. each of them separately around 500mb when store them csv. separately fit memory when load both memory error. trouble when try merge them pandas. what best way outer join on them don't memory error? don't have database servers @ hand can install kind of open source software on computer if helps. ideally still solve in pandas not sure if possible @ all. to clarify: merging mean outer join. each table has 2 row: product , version. want check products , versions in left table only, right table , both tables. pd.merge(df1,df2,left_on=['product','version'],right_on=['product','version'], how='outer') this seems task dask designed for. essentially, dask can pandas operations out-of-core, can work datasets don't fit memory. dask.dataframe api subset of pandas api, there shouldn't of learning curve. see dask dataframe overview page additional data

we have 10 sensors (with analog digital converter) ble slaves, , slaves triggered master sensors can start sampling @ same time. possible ble? if not, smallest latency (or time skew) between 2 slaves getting triggered? the best way first connect 10 devices short connection interval (like 10 ms or whatever). once done, send write commands 10 of them @ same time. long bluetooth controller can fit 10 enqueued packets, of them sent in next connection event each ble slave. time skew within connection interval.

in windows (visual studio c++ 2010) i'm trying simple string copy. here's code: char * filename; (...) filename = (char *) malloc(wcslen(argv[(i + 1)]) + 1); wcscpy((wchar_t *)filename, argv[i + 1]); wprintf(l"filename is: %s", filename); and program crashes if argv[i + 1] if bigger 14. if 14 or less runs fine. see bellow. c:\visual studio 2010\projects\test\release>test.exe -f 12345678901234 aa asas asas first argument argv[1] -f argc = 6 filename is: 12345678901234 what's gotcha here? missing? thanks. realise wcslen() returns number of wide characters in string, not number of bytes occupies. , malloc() requires number of bytes... so need multiply number of wide characters size of wide character before passing malloc() : filename = (char *) malloc( (wcslen(argv[(i + 1)]) + 1) * sizeof(wchar_t)); but then, you're typecasting (char *) . if argv declared char *argv[] or char **argv , wcslen() wrong function use anyway: nee

when want upload image on server, script doesn't have rights write file. however, script execute localy , rights of folder 0775. ...# chmod -r 0775 img drwxrwxr-x 2 root root 4096 jun 11 10:56 img but, when put rights in 0777, it's work. there has solution not allowing write directory ? thanks ! the upload directory needs owned user write file (in case user web server process running under) or upload directory needs have group ownership group of web server process user member. so example if webserver user apache , web server user member of group apache, solve by chown apache /path/to/upload/directory or chgrp apache /path/to/upload/directory any script running on webserver have write access upload directory.

i reading an article javascript prngs , , came across surprised me: var = new array(); var b; a[b++] = 1; a [] , no exception thrown — the write array vanishes. try out in browser console if don’t believe me. i didn't believe him, tried out in browser console (firefox 47): » var = new array(); » var b; » a[b++] = 1 » ← array [ ] » b ← nan there several curious things going on here, in particular, i'm trying understand why statement a[b++] = 1 doesn't [appear to] anything. taking top: var = new array(); // 'a' empty array, plain ol' boring empty array, have been // written = []; var b; // 'b' have no value , 'undefined'. 'console.log(b); // undefined' a[b++] = 1; // lets break above statement down pieces: b++ // increment b one, undefined + 1 === nan a[ ] // use nan property our array 'a' = 1; // assign 1 property // ok? happened why 'a' still empty? console.log(a);

i'm trying c# fscheck generator generate series of commands initialized random strings. came following solution: public gen<command<a,b>> next(b value) { var gen1 = arb.default.string().generator; var gen2 = gen.two(gen1); var gen3 = gen2.select((command<a,b>)(s => new derivedcommand(s.item1,s.item2))) //derivedcommand extends command<a,b> return gen.oneof(gen3); } however, vs cannot build code: cannot convert lambda expression type command<a,b> because not delegate type i have searched solutions error message, nothing found helped. using system.linq , system.data.entity . suggestions resolving issue appreciated. you're trying cast (s => new derivedcommand(s.item1,s.item2)) , lambda expression, (command<a,b>) , (i assume) class. you need like: var gen3 = gen2.select(s => (command<a,b>)(new derivedcommand(s.item1,s.item2)));
