7 hours (9:33 am) morning, i had question regarding instructions of libcudnn tensorflow in python. ive put folders , added respective path , environment variables, after instructions indicate add compiler , link lines. dont understand mean. give me advice on how or reference learn line concepts? i'd appreciate it. linux cd <installpath> export ld_library_path=`pwd`:$ld_library_path add <installpath> build , link process adding -i<installpath> compile line , -l<installpath> -lcudnn link line. in normal installation, works. ld_library_path tells tensorflow cuda dynamic libraries are. if installed them with-apt-get, or if using nvidia-docker container, there might nothing else do. if installed bazel, should not have tinker compile flags. if found in current documentation, let know , can update docs. for installation issues, better equipped answer questions on our github page, can have longer-form submission , discussion: https://github....

i way how inject input events such touch or keyboard events own application, code within particular app. not android os or other apps b/c needs signature-level permission android.permission.inject_events or rooted device , have avoid both. code runs on non-rooted device without anyhow elevated rights. i'm somehow making bit of progress code based on following concept: view v = findviewbyid(android.r.id.content).getrootview(); v.dispatchtouchevent(e); i think getrootview , dispatch should works well, if there problem it. please brief it. or there more high level tricky way this. in view.java, there hide api called getviewrootimpl() return object of android.view.viewrootimpl of activity. , there method called enqueueinputevent(inputevent event) on it. can use reflection method. as have finished project using keyboard send touch commands screen, think when trying inject these kind of events activity, multiple touch might problem. when try send finger screen. eve...

i'm using foundation framework website , there's white-space around the whole body (the gutter). remove gutter i've tried: *{margin:0;padding:0;} body{margin:0;padding:0;} downloading custom foundation gutter set 0 none of has worked out me. can done remove white-space? here's screenshot gutter highlighted red this not margin issue max-width issue. using devtools you'll find .row class has max-width of 62.5rem, think standard. (i work on site has modified width of 72.5rem.) i think it's idea maintain version of limitation if have normal page content people have read on large screens. can safely override want 100% width. you can adding class overrides default max-width , selects relevant element sufficient specificity in style sheet. alternatively, can refrain using class .row on outer containers want span page. allows option of putting rows within. way could, example, have teal background span page keep content constrained , aligne...

i want ask mysql innodb suggest getting smaller database? i not have innodb_file_per_table not need reclaim space(this have been nice see how space able save). most of strings saved utf8mb4. columns use latin1(i know there can there latin characters). think save lot of space if convert them latin1? seems change should performance increase in searches. i have defined columns have lot of text mediumtext . think should save space if define column text? - see type acts varchar(it occupies length of string) what other suggestions have? the database has more 300 millions rows , stored in 100g thanks changing character set not help. when use utf8 or utf8mb4, each character stored in variable number of bytes. characters can stored in single byte stored way. changing mediumtext text not much. each string in such columns stored in variable length, length needed string stored. text can store strings 64kb, mediumtext can store strings 16mb. suppose each such string may n...

how can create perl subroutine take in array , find longest common prefix 2 or more of elements? (strings) i have code: sub longest_common_prefix { $prefix = shift; (@_) { chop $prefix while (! /^\q$prefix\e/); } return $prefix; } but works if looking longest common prefix of all strings. for example, if pass array following strings: aaabgfb aaajjjj jjfkbbb aaahghg i want return aaa answer. thanks! one way store information in hash. in example, set hash key length of each prefix, , value being actual prefix found. note method overwrites key , value if same-length prefix exists, you'll last prefix found of longest length ( sort() takes care of finding longest one). the regex says "find first character in string , capture it, , use char found in second capture, , capture many there are". string join() ed scalar , put hash. use warnings; use strict; %prefixes; while (<data>){ $prefix = join '...

for reasons , need compile linux kernel (currently 4.7.10) passing simple , innocent additional command line options (e.g. -pipe -wsomething etc) c compiler. how do it? more specifically, how enforce these compiler flags during plain make during make menuconfig , similar, i.e. passed c compiler whenever latter executed. ps: beg please not ask me details why need stupid this. satisfactory explanation take me several hours write, not 1 of best skills. from linux kernel's makefile: # add arch overrides , user supplied cppflags, aflags , cflags # last assignments kbuild_cppflags += $(arch_cppflags) $(kcppflags) kbuild_aflags += $(arch_aflags) $(kaflags) kbuild_cflags += $(arch_cflags) $(kcflags) so, passing additional options kbuild uses usual environment/makefile variables k prefix: make "kcflags=-pipe -wsomething"

so, i'm working on exercise questions. code seems working fine until decide loop through string replace instance of period nothing. reason, loop doesn't work. imagine has not calling somehow, i'm not sure how call loop. thought loops automatically overwrote looping through. here exercise , incomplete solution: write javascript function parameterize string. function string_parameterize(string) { var lowercase_string = string.tolowercase(); var split_string = lowercase_string.split(" "); var joined_string = split_string.join("-"); (i = 0; < joined_string.length; i++) { if (joined_string[i] === ".") { joined_string[i] === ""; } } return joined_string; } //test data : console.log(string_parameterize("robin singh usa.")); the answer should robin-singh-from-usa without period, keeps coming out robin-singh-from-usa. period. the other...

my board nodemcu devkit v1.0. have been trying flash nodemcu custom build using cloud service.(on top of standard selected ones add dht library) binary name nodemcu-master-8-modules-2016-11-03-03-23-44-integer believe uses master build 1.5.4.1 first attempt: i used esp8266flasher.exe windows. selected custom build binary , flashed address 0x00000.(baud:230400 flash speed:40 mhz spi mode:dio flash size:4mbyte) at point board repeatedly rebooting(blue led going on/off @ high frequency) so have gone through documentation , learned problems due change of esp_init_data_default.bin when upgrade nodemcu 0.9 build. second attempt: i used erase_flash using esptool.py esptool.py --port /dev/tty.slab_usbtouart erase_flash and flashed custom build again. third attempt: i did erase_flash via esptool.py. time downloaded sdk patch 1.5.4.1 , flashed esp_init_data_default.bin address 0x3fc000 custom build 0x00000. there no rebooting error when ran esplorer , connect board fol...

i'd know how scatter plot 1 column(a) values x axis , other column(b) y axis. each row have redundant values in column different values in column b. i'd plot unique values in x axis. e.g. a b groupa 10 groupb 20 groupa 30 groupc 5 groupb 11 in x axis, plot group a, b, c without redundancy. in y axis, plot each values belong each group. instead of setting x axis values manually pre defining {groupa,groupb,groupc}, read observations automatically column , saves array , plot it. can me start this? thanks, the easiest way achieve setting 2 scales, 1 ordinal scale x axis, scalepoint , , 1 linear scale y axis. this x scale: var xscale = d3.scalepoint() .domain(data.map(function(d){return d.a})) .range([50, width-50]) .padding(0.5); and y scale: var yscale = d3.scalelinear() .domain([0, d3.max(data, function(d){return d.b})*1.1]) .range([height - 50, 10]); here demo: var data = [{a: "gr...
