i'd have bats test created every file in directory, i'm not sure best way done is. approach below creates single test when there many files in directory. #!/usr/bin/env bats in $(ls) @test "testing $i" { pwd } done to extract ls output not batter solution go wrong on filenames spaces. you can below shopt -s nullglob file in /dir/* //test command on $file done shopt -u nullglob you can using find command also find /some/directory -maxdepth 1 -type f -exec cmd option {} \;

i'd access values in maps , records, throwing exception when key isn't present. here's i've tried. there better strategy? this doesn't work because throw evaluated every time: (defn get-or-throw-1 [rec key] (get rec key (throw (exception. "no value.")))) maybe there's simple method using macro? well, isn't it; has same problem first definition, if evaluation of throw happens later: (defmacro get-or-throw-2 [rec key] `(get ~rec ~key (throw (exception. "no value.")))) this 1 works letting get return value (in theory) never generated other way: (defn get-or-throw-3 [rec key] (let [not-found-thing :i_would_never_name_some_thing_this_021138465079313 value (get rec key not-found-thing)] (if (= value not-found-thing) (throw (exception.

some docs says, there "undo tablespaces" implies should create tablespace undo imformation. some docs says, there "undo segment" implies undo information lives in normal tablespaces , use of it's segment. so, undo information lives , organized? earlier releases of oracle database used rollback segments store undo. oracle9i introduced automatic undo management, simplifies undo space management eliminating complexities associated rollback segment management. oracle recommends (oracle 9i , on words) use undo tablespace (automatic undo management) manage undo rather rollback segments. when creating undo tablespace, these automatically created: n undo segments (based on sessions parameter value) named _syssmun$ owned public (usable ops configuration) not manually manageable

we have calculate numbers of "this" in given string having multiple "this" substrings. eg. "hello recruit , veteran , this" return 4. so using: stringtokenizer stringtokenizer1 = new stringtokenizer(input2); arraylist<string> arraylist1 = new arraylist<string>(); int count=0; int arrindex = stringtokenizer1.counttokens(); (int = 0; < stringtokenizer1.counttokens(); i++) { arraylist1.add(stringtokenizer1.nexttoken()); } (string string2 : arraylist1) { if (string2.equals(string)) { count++; } } output1 = count; system.out.println(output1); return 2. however, if int arrindex assigned value of stringtokenizer1.counttokens() , used in looping condition, it's giving correct result of 4. why?? note:using javase-1.6 the condition stringtokenizer1.counttokens() evaluated everytime reenter loop. per javadoc calculates n

i'm using excellent gpuimage blur views ( https://github.com/bradlarson/gpuimage ) however, seems first couple of times blur views, it's slow. after few blurs, it's faster. why that, , there way preload gpuimage framework fast time? thanks gpuimageiosblurfilter *blurfilter = [gpuimageiosblurfilter new]; blurfilter.blurradiusinpixels = 1; blurfilter.saturation = 1.2; blurfilter.downsampling = 4.0f; blurredimage = [blurfilter imagebyfilteringimage:blurredimage]; there slight lag on first usage of given filter, because framework has compile shaders used filter. these shaders cached later reuse. blurs in particular exhibit this, since shaders generated each blur radius use (for performance reasons when reused in video, etc.). that said, make sure absolutely need work uiimages in above code. -imagebyfilteringimage: isn't fastest approach, since has take in uiimage, generate gpuimagepicture behind scenes, upload image texture, proce

i have written script create images in loop , loop size 10k. happens after period of time browser shows "the connection has timed out". can still see images being created in specific folder i.e apache still processing request. the point of concern happens http aapche server requests sent in loop after connection has timed out. i curious know apache queue system in detail. you may looking ignore_user_abort directive. there more timeouts in place. apache request timeout (the time apache lets user wait first data). may different max_execution_time in php. if ignore user abort enabled, both timers start. after time apache times out , sends reponse. script in background still runs until either finishes or max_execution_time reached. if disable ignore user abort, script stopped when apache sends timeout user.

while indexing document, elasticsearch automatically create mapping missing fields (inside document) is possible configure (or) there configuration can instruct elasticsearch not create missing fields, instead ignore. basically, use java pojo, use instance of same pojo index document (by converting instance json using gson library) , use of fields in pojo external purpose. so when set fields used external purpose, send document elasticsearch, these additional fields saved. want avoid that. yes, possible disable dynamic mapping feature within elasticsearch mappings not created dynamically when new fields ingested. documentation: dynamic mapping when elasticsearch encounters unknown field in document, uses dynamic mapping determine datatype field , automatically adds new field type mapping. sometimes desired behaviour , isn’t. perhaps don’t know fields added documents later on, want them indexed automatically. perhaps want ignore them. or — e

we have baseobject 10 childobjects , ef6 code first. of 10 childobjects, 5 have few (extra) properties, , 5 have multiple properties (5 20). implemented table-per-type, have 1 table base , 1 per child (total 10). this, however, creates huge select queries select case , unions on place, takes ef 6 seconds generate (the first time). i read issue, , same issue holds in table-per-concrete type scenario. so left table-per-hierachy, creates table large number of properties, doesn't sound great either. is there solution this? i thought maybe skip inheritance , create union view when want items child objects/records. any other thoughts? thanks in advance. another solution implement kind of cqrs pattern have separate databases writing (command) , reading (query). de-normalize data in read database fast. assuming need @ least 1 normalized model referential integrity, think decision comes down table per hierarchy , table per type. tph reported alex james ef t

i have problem, rather close binary search in sorted (memory-mapped ?) file in java i want implement binary search string in large file java mappedbytebuffers in case, large file compressed bzip2. let's file compressed -1 option 100k block. (actually don't know exact options can repak file). how should search strings in such mappedbytebuffer? how decompress 1 block? there standart lib or should read header, deflate section , crc? , block 100k in compressed state, or 100k it's uncompressed data length? , how last block looks like? have done binarysearch on compressed file, maybe not java? you need read file index of each block starts. once have can binary search of blocks. note: if have underlying record or key, split across multiple blocks. a better solution build compressed file yourself. write known number of records block , compress individually. additionally can write index each block starts first key block. allow find right block without deco

as far know there no information available browser find out client's ip address without making call resource. is there way store client's ip address? mean in similar way firebase.timestamp placeholder works. although i've heard there ways clients determine , report ip address, relying on client side code report ip address opens ability run custom client side code report wrong ip address. the secure way of keeping track of clients' ip addresses either involve having server, or firebase having special function, when called client, causes firebase's server grab client's ip address , save you. my recommendation run simple server can take post request. server needs able verify user request coming from, , able accurately grab client's ip address , save on firebase.
