i think missing obvious trying work @ngrx . trying use nested reducers, , want able return default starting child values. child export const counter:reducer<number> = (state:number = 0, action:action = {type:null}) => { switch (action.type) { my question how use initialise counter. counters.ts looks like export const counters:reducer<number[]> = (state:number[] = [], action:action) => { switch (action.type) { case add_counter: return [counter(), ...state]; this works have typescript error on counter: supplied parameters not match signature of call target , i'm wondering how around this. i'm using @ngrx, provides this: export interface action { type: string; payload?: any; } export interface reducer<t> { (state: t, action: action): t; } export class store<t> extends behaviorsubject<t> { private _storesubscription: subscription<t> constructor(private _dispatcher:dispatche

i feel dumb , ashamed. started learning jquery , got stuck @ first day. basically, building of in ruby on rails, , have list of clients basic info name, address, phone number, etc. in picture below page layout (yes, know.. born artist). in left table, display clients have in database, first column represents client's id , second column shows names. in right table (it partial), display full client's info. my objective this: clicking on row, on left table, right table update , show info related client selected. here tried : <script> $('#table_clients tbody').on('click', 'tr', function() { $("#container_info").replacewith( '<%= j render :partial => "client_info", :locals => {:client => 1} %>' ); }); </script> notice manually specified client's id. my question is, how can identify row selected , pass id erb fragment ? i can id calling this: $(this).find(':nth-child

in python programs (django or web.py), write logs stderr. e.g. sys.stderr.write('tab\tcharacter') when serving these programs via apache, logfiles has literal "\t", , not real tab (ascii=9) if test program command line, see real tabs. it's in apache. is there feature in apache logs converts tab character \t ? is there way work around , see tabs in apache log files? edit i gave up. instead of \t i'm using character separator... try: a = "tab" + chr(9) + "character" sys.stderr.write(a) no?

hi getting following error when trying run perl script: pc:~/phd/lenovo/programs/vep/scripts/variant_effect_predictor$ perl variant_effect_predictor.pl --help universal not export @ /home/arron/phd/lenovo/programs/vep/scripts/variant_effect_predictor/bio/tree/treefunctionsi.pm line 94. where offending line is: use universal qw(isa) what issue? from documentation of universal : previous versions of documentation suggested using isa function determine type of reference: use universal 'isa'; $yes = isa $h, "hash"; $yes = isa "foo", "bar"; the problem code never call overridden isa method in class. instead, use reftype scalar::util first case: use scalar::util 'reftype'; $yes = reftype( $h ) eq "hash"; so method not exist anymore.

using "send_task" celery never verifies remote task exists i.e: app.send_task('tasks.i.dont.exist', args=[], kwargs={}) celery seems still return message i.e.: <asyncresult: b8c1425a-7411-491f-b75a-34313832b8ba> is there way fail if remote task not exist? i've tried adding .get() , freezes. according documentation: if task not registered in current process can execute task name. you using send_task() method of celery instance if want verification consider using delay instead. you can read more how execute celery tasks here .

when c array created using malloc, array stored in heap, , when c array created statically stored in stack. however, happens if return element of c array initialized statically function? wording may strange, here example: #include <stdio.h> #include <stdlib.h> char getstaticelement(); char getdynamicelement(); int main() { char dynamicelement = getdynamicelement(); char staticelement = getstaticelement(); printf("dynamic element: %c\n", dynamicelement); printf("static element: %c\n", staticelement); return 0; } char getstaticelement() { char staticarray [] = {'a','b','c'}; return staticarray[1]; // returns b } char getdynamicelement() { char * dynamicarray = malloc(sizeof(char)*4); dynamicarray [0] ='a'; dynamicarray [1] ='b'; dynamicarray [2] ='c'; dynamicarray [3] ='\0'; return dynamicarray[1]; // returns b } so staticelement in memory?

scenario: i have mysql myisam table (table1) 11 million rows, of want copy better table (table2, has innodb engine along proper indices). since adding indexes myisam table takes long want loop through entire table , copy every row new table. is there way within mysql? conditions: there no time limit action (could looped "slowly"). the tables have same columns. table1 online , needs stay online (being read time; i've temporarily paused writing). problems: mysql server shared host (no file system access). mysqldump times out. adding index times out. simply inserting select of previous table times out. idea: perhaps 1 loop mysql statement, doing 10 000 @ time or that? this works 1 (1) record: insert products_indexed select * products products.p_product_id=( select products.p_product_id id products left outer join products_indexed on ( products.p_product_id = products_indexed.p_product_id ) products_indexed.p_product_id

i have basic understanding of merge sort algorithm. reason can't wrap head around values low , high coming from. code working merge. void practicemerge(int a[], int low, int mid, int high) { int b[10000]; int = low, j = mid + 1, k = 0; while (i <= mid && j <= high) { if (a[i] <= a[j]) b[k++] = a[i++]; else b[k++] = a[j++]; } while (i <= mid) b[k++] = a[i++]; while (j <= high) b[k++] = a[j++]; k--; while (k >= 0) { a[low + k] = b[k]; k--; } } let me explain commenting code: //sort array index low index high merging 2 //subarrays of go low mid , mid high. void practicemerge(int a[], int low, int mid, int high) { int b[10000]; //buffer int = low; //starting index in first sub array int j = mid + 1; //starting index in second sub array int k = 0; //starting index in buffer //while not go beyond limit of first subarray

i trying use networkx calculate numeric assortativity based on numeric attribute set nodes. node attributes floats. when call assortativity function: assort = nx.numeric_assortativity_coefficient(g,'float_attr') i got following errors. file "/some dir.../networkx/algorithms/assortativity/correlation.py", line 229, in numeric_assortativity_coefficient = numeric_mixing_matrix(g,attribute,nodes) file "/some dir.../networkx/algorithms/assortativity/mixing.py", line 193, in numeric_mixing_matrix mapping=dict(zip(range(m+1),range(m+1))) typeerror: range() integer end argument expected, got float. i checked documentation page of networkx assortativity algorithm , did not numeric attributes have int. knows if that's required? btw, used same network , gender attribute (set 0 , 1) calculate both attribute , numeric assortativity. had no problem that. seems problem int/float type of node attribute. problem solved converting float variable i

what i'd apply autoindex on; @ root folder , afterwards (as user selects folder) use traditional "index.php" files if available , defined in index index.html index.htm... etc. don't know number of folders inside root neither names. how can done, given these restrictions? you can define regular expression location match uri below root, example ./ this block should placed below location ~ \.php$ (or similar) php scripts continue handled correctly. see this document . location / { autoindex on; } location ~ \.php$ { ... } location ~ ./ { index index.php; }

i've been improving sql knowledge still failed understand how create queries. i have following tables in sql server database: user(id, name) loan(id_sender, id_receiver, amount, date, date_payment) what valid query to: select name of users have sent loans user both in 2014 , 2015 select pairs (id1, id2) of users have sent loans each other any suggestions appreciated! edit 1: my attempts: 1. select name user id in ( select id_sender loan id_receiver in (select distinct id_receiver year(date) = 2014) , id_receiver in (select distinct id_receiver year(date) = 2015) ) 2. select id1, id2 ( select distinct id_sender id1 loan id_receiver in ( select distinct id_sender loan id_receiver = ??? ) (?) ) example 1: in case date column has index, it's best not use function around column can utilize index. select name user id in (select id_sender loan date >= '1/1/2014' , date < '1/1/201

i have following 3 algorithms give fibonacci numbers. know how able find out each of order of complexity. know how might able determine this? method 1 ------------------------------------------------------------------------ long long fibb(long long a, long long b, int n) { return (--n>0)?(fibb(b, a+b, n)):(a); } method 2 ------------------------------------------------------------------------ long long int fibb(int n) { int fnow = 0, fnext = 1, tempf; while(--n>0){ tempf = fnow + fnext; fnow = fnext; fnext = tempf; } return fnext; } method 3 ------------------------------------------------------------------------ long long unsigned fib(unsigned n) { return floor( (pow(phi, n) - pow(1 - phi, n))/sqrt(5) ); } correct me if wrong, guess method 1 o(2^n) since recursive, medtod 2 o(n) , last 1 o(1) . methods 1 , 2 have complexity o(n) . reasons straightforward: method 1 recurses n-1 times, each recurs

okay, have static world (can't resized). know how can convert arraylist instead of current situation: for(int xp = 0; xp < world_size_x; xp++) { for(int zp = 0; zp < world_size_z; zp++) { for(int yp = 0; yp < world_size_y; yp++) { } } } my question is, how can make can use for(int = 0; < blocks.length; i++) {} but still [x][y][z] coordinates? currently i'm using block: blocks[x][y][z]; how xyz dynamic arraylist? if need more information, please tell me. i'll glad understand situation. arraylist's equivalent of .length .size() , , equivalent of [...] .get(...) . that said, arraylist<arraylist<arraylist<...>>> pretty unwieldy structure work with; , although it's theoretically "dynamic", in practice it's difficult resize, because resizing involves creating many new elements have initialize. if goal merely able specify size @ runtime (but

i understand best practice dealing database operations. i use mongoose package, change mongodb package, cause don't need much, , know if should end connection after operation or leave open?? also, i'm using redis queue node-resque , have same doubt. i'm leaving both open, never close, doing wrong? also, extending express instance - app - queue operation, can use in anywhere, wrong too? thanks. mongodb it best practice open connection on application initialization , either have mongodb driver of choice manage connection pool (as drivers do, including js driver) or derive new connections "master" connection (as practice in go driver). the reason why makes sense have driver manage connection pool simple: when number of connections left in pool drops below threshold, relative expensive operation of creating new socket connection mongodb , maybe authenticating done in background. when new connections requested application, not need created. r

i have these results: >> size fives 1 5 >> size(fives) 4000 17 the latter accurate. i'm not sure former doing @ all. when type size no args error: error using size not enough input arguments. so i'm not sure why "fives" , "(fives)" both count arguments different things. in matlab, size without parenthesis gets size of literal string. example, size abcdefg 1 7 if abcdefg not defined variable.

i reading csapp, in chapter 4, there discussions cpu pipelining features author talks how many instructions non-pipelining cpu can execute within 1 second vs pipelining cpu. post screenshot follows: in figure 4.32(a) shows unpipelined cpu. in implementation, must complete 1 instruction before beginning next. big box combinational logic. author regard whole process instruction , calculates throughput 3.12 gips shown in formula. then author use figure 4.33 show pipeline computation: in pipeline computation, combinational logic can divided 3 stages i1, i2 , i3. here question: in opinion, because these 3 stages combined product effect of combinational logic, think of 3 stages single instruction author did in unpipelined example. however, author seems regard 3 stages 3 instructions, , got throughput of 8.33 gips follows: so curious definition of instruction? (if think of writing registers instruction, author's answer correct)

is there way can iteration number inside angular foreach (when iterating through object : {'foo': 'blah', 'blah': 'foo'} ? iterator function in case, value 'blah' , 'foo' while key 'foo' , 'blah' angulars foreach when iterating object doesn't tell how many times iterated objects keys. when iterating array doesn't tell how many times ran current position in array. it's me being pedantic there difference. however alternative give current position in objects keys use native object.keys() . return array of objects keys, can iterate on them normal array , current position in array. var obj = {'foo': 'blah', 'blah': 'foo'}; object.keys(obj) .foreach(function (key, index) { console.log('key', key, 'value', obj[key]); console.log('ive ran ', index); }); docs: https://developer.mozilla.org/en-us/docs/web/javascript/r

having output of list of lists containing index values of grouped elements (somewhat) corresponding list of tuples, how combine them list of grouped tuples? data=[(1, 1), (1.5, 2), (3, 4), (5, 7), (3.5, 5), (4.5, 5), (3.5, 4.5)] clusters=[[0], [], [4], [1, 2, 3, 5, 6]] these sample values/groups. example of i'm asking about: coordinates= [[(1,1)], [], [(3.5,5)], [(1.5,2),(3,4),(5,7),(4.5,5),(3.5,4.5)]] i've tried list comprehensions , zips when comes getting value of [i] in clusters gets confusing. i think two-level list comprehension want: coordinates = [[data[index] index in cluster] cluster in clusters]

what best way following? i reverse smaller range in vector , haven't found better solution this: extract smaller range newly created vector, reverse , add newly created vector @ former position in original vector. another way explain want this: original vector: 1 2 3 4 5 6 7 8 9 10 11. wanted result:   1 2 3 4 5 6 7 10 9 8 11. copy 10, 9, 8 in order new vector 3 element or copy element 8, 9, 10 new vector reverse it. original vector consists of 9 elements because elements 8, 9, 10 erased in procedure. 2.the new vector 3 elements 10, 9, 8 copied/appended original vector @ position 8 vector or element element @ position 8, 9, 10 respectively. i sure there better solutions method mentioned above. you in fact write in-place swap, that gets last , first index swap, swap these, decreases last index , increases first index, and repeats until last_index - 1 <= first_index . now, sounds less copying me, stroustrup himself once said: i don't
