does use matlab wrapper caffe framework? there way how extract 4096 dimensional feature vector image? following https://github.com/bvlc/caffe/issues/432 and tried remove last lines in imagenet_deploy.prototxt remove layers suggested in forum on github. but still when run "matcaffe_demo(im, 1)" 1000 dim vector of scores (for image net classes). appreciated kind regards it seems might not calling correct prototxt file. if last layer defined in prototxt has top blob of 4096 dimension, there no way output 1000 dimension. to sure, try creating bug in prototxt file , see whether program crashes. if doesn't program indeed reading other prototxt file.

this question has answer here: what's best way last n elements of perl array? 5 answers if have array i've used create 50 random numbers, sort them numerically. lets wanted print out 10 biggest number (elements 40 50) say: print($array[40]) print($array[41]) print($array[42]) etc etc. there neater way it? hope i'm making myself clear. cheers you loop on indexes. say $array[$_] 40..49; offsets end make more sense here. say $array[$_] -10..-1; you use array slice. say @array[-10..-1]; to print them on 1 line, can use join . say join ', ', @array[-10..-1];

so have js adds style attribute css filters. have added both webkit-prefixed , unprefixed version of property, this: <img src="image.jpg" style="filter: blur(10px); -webkit-filter: blur(10px)"/> i need save html , display in different browser. however, filters aren't visible in different browsers, because unknown attributes removed. example, if filters added in webkit, non-prefixed property removed browser, preventing html later working in firefox. way override browser's removing unknown properties style attribute, unprefixed version visible in different browser. know can add js recalculates filters on pageload, prefer not this. there better solution? i have example here , can see (e.g. in chrome) style attribute not updated css attributes don't apply and $().html() will only. in problem may don't need prefixes. worth notice fact, taken jquery decumentation, that as of jquery 1.8, .css() setter automatically take

i have view. want function returns rows view; however, need change 1 value in each of rows return. i can using select , writing field names in select clause , listing values including 1 change, makes code obscure. seems want light weight temporary table. want write like: update { select * myview f(row,x,y) } set column = y where x , y arguments function, column column name myview, , f function. is there can write? thanks. some pointers: you can view in have list columns separately: create view myviewmodified select y column, ... myview; , after can use select * myviewmodified f(row,x,y); you write select y column1modified, * myview; in code , use column1modified. way can use asterisk-symbol. listing values might make code obscure if drive code through poor sql can make quite clean (it helps if accustomed reading sql queries). why select * considered harmful?

i used astuetz library , implemented pagerslidingtabstrip android application, it's working find. want change pressing effect, tried: android:background="@drawable/tab_selecor" code tab selector: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@color/darkgreen" android:state_focused="true" android:state_pressed="true" /> <item android:drawable="@color/darkgreen" android:state_focused="false" android:state_pressed="true" /> <item android:drawable="@color/green" /> </selector> the press colour suppose changed dark green see not change, still looks if use colour red, yellow, .... . make use of setindicatorcolor() setting color of indicator , setindicatorheight() setting height and make use of settabbackground() method

writing stored procedure parse names in format 'last first mid' , 'last first mid suffix' table. create procedure parse_full_name(full_name text) begin set @last_name = substring_index(full_name, ' ', 1); set @middle_name = substring_index(full_name, ' ', -1); set @first_name = substr(full_name, locate(' ', full_name), length(full_name) - length(@middle_name) - length(@last_name)); set @query = concat('select ''', @last_name,''' last_name, ''', @first_name,''' first_name, ''', @middle_name,''' middle_name;'); prepare stmt @query; execute stmt; deallocate prepare stmt; end; call parse_full_name('last first middle'); >>> last_name | first_name | middle_name >>> -----------|------------|------------- >>> last | first | middle call parse_full_name('last first middle suffix

i trying have thumbnail grid. each thumbnail can have either 1 of 2 different height, want whole row have same height as can seen, because last 2 thumbnails higher, rest get's pushed down. when inspect google devtools, no padding or margin has been added, they're being forced down somehow css: .video { display: inline-block; width: 220px; height: 250px; margin: 0 0 15px 15px; h4 { margin-top: 5px; } .thumbnail { padding: 0px; border: none; background: none; // box-shadow: 5px 5px 15px -6px; .caption { word-break: break-all; } } } html: <div class="row"> <div class="col-xs-12"> <div class="videolist"> <div class="video"> <div class="item"> <div class="thumbnail"> <img src="https://i.ytimg.com/s_vi/yxqdrjjiqjy/hqdefault.jpg?sqp=cnjotkgf&amp;rs=aon4cl

the question this-- we have find minimum number of characters inserted at end of string make palindrome. so, in efforts problem, figured equivalent finding largest palindromic substring suffix of string. i in o(n^2) looking o(n) solution possible using modified kmp. please me figure out. i have approach uses hashing posted answer here . you can indeed use kmp. can compute prefix function reversed string, , iterate initial string left right: kmp computes function prefix[i] = longest prefix of string suffix of string[1..i] however, want know the longest suffix of our string prefix of reversed string . why? if have: 15232 => reverse = 23251 then longest suffix of string prefix of reversed string 232 . palindrome, , lets find you're asking because suffix of string overlaps prefix of reversed string if 2 palindromes. you have cases: prefix[i] = length - => can palindrome of length 2*prefix[i] centered @ , i+1 prefix[i] = length - +

when run traceroute against domain name hit cloudflare cache. avoid this, i'm trying run traceroute against path on domain know isn't cached, this: > traceroute domain.com/some/path traceroute: unknown host domain.com/some/path is there way traceroute against path work?

i stumbled on interesting while working in visual studio c++. calling function made set pixels screen through nested loop, x , y screen coordinates. discovered if did operations in main() function program run @ 250 frames per second, yet if moved outside function , called frame rate dropped 30 frames per second. i did investigating test program, , replicated happened in program. below illustration of did.... if run following program.... void main() { (int = 0; < 1e9; i++) // loop billion times { 1+1; // } } it runs in 1.6 seconds. however, if run following code, same thing except calling outside function.... void oneplusone() { 1+1; } void main() { (int = 0; < 1e9; i++) // loop billion times { oneplusone(); // call function instead } } it takes 18 second execute. now, can avoid calling function , have code need in main(), makes messy , unreadable. please tell i'm doing wrong or i've got visual studio sett

i have table used identity primary key (t_head_id), key became long way upsets client, changed normal column select max + 1 , added new identity column ( id ) , 1 computed ( id_per_year ) id_per_year=id+'-' year(opeartion_date) the prob want reset id not @ beginning of year when client starts inserting new values of operation_date , since new year can started client still inserting records of passed year how can reset identity based on changing value of operation_date? you define column of type int (or smallint, tinyint, bigint ) identity attribute: create table dbo.yourtable( id int identity(1,1) ...... with setup, sql server automatically generate consecutive id's table when rows being inserted table. with type int , starting @ 1, over 2 billion possible rows - should more sufficient vast majority of cases. bigint , 922 quadrillion (922 15 zeros - 9'220'000 billions) - enough you?? if use int identity starting @ 1, , insert row every

as title says, i'm developing in c#. i'd generate number has more 9 numbers, thought generating numbers, follow 9. instance, if want generate number has 10 digits - i'd generate first number has 9 numbers, , number has 1 digit. if generate number 20, i'd generate first 2 numbers 9 digits each, , number 2 digits. i've tried: for (int = 0, j = (int.parse(inputrandom.text) % 9 == 0 ? int.parse(inputrandom.text) % 9 : int.parse(inputrandom.text) % 9 + 1); < j; i++) if (i < (int.parse(inputrandom.text) % 9 == 0 ? j % 9 : j % 9 + 1) - 1) numtosend += (biginteger)r.next(int.parse(1 + zero((int.parse(inputrandom.text) % 9 + 8) * (inputrandom.text.length - 1)))); else numtosend += (biginteger)r.next(int.parse(1 + zero(int.parse(inputrandom.text) % 9 * 9))); the method 0 returns string 0, times number specified in. i.e zero(1) return: "0" need method because method next(int32) can return number, specified between brackets

for example, have function (need c99) void fun(int nx, int ny, double a[nx][ny]) { // code here } and have pointer double *p = new double[nx * ny]; and use call function like fun(nx, ny, p); // error type not matched how it? type conversion allowed. what want not possible in c++ because c++ requires sizes of array types compile time constants. c99 not have limitation, function declaration void fun(int nx, int ny, double a[nx][ny]); is valid c99, not valid c++. btw, in c99, correct call of function this: int nx = ..., ny = ...; double (*matrix)[ny] = malloc(nx*sizeof(*matrix)); fun(nx, ny, matrix); now, have 2 possibilities: use c multidimensional array stuff. use c++ workaround this. the easiest c++ workaround vector<vector<double> > . avoid hassle of allocating memory yourself, however, rows in 2d matrix not consecutive. you can use 2 layer indirection this: double **matrix = new double*[nx]; for(int = 0; < ny; i++) ma
