i building codeigniter based file browser having problem file information. i have loaded helpers: $this->load->helper('file'); $this->load->helper('directory'); when called var_dump(get_file_info('gui/default/uploads/profile_200x200.jpg')); here result: (note path relative site_url() ) array (size=4) 'name' => boolean false 'server_path' => string 'gui/default/uploads/subfold/profile_200x200.jpg' (length=47) 'size' => int 9714 'date' => int 1386054354 but when called get_filenames() or get_dir_file_info() same built-in file helper displays filenames correctly. experience or idea causes this? due bug function (read here ) use workaround: $file = 'gui/default/uploads/profile_200x200.jpg'; $fileinfo = get_file_info($file); if(!$fileinfo['name']) $fileinfo['name'] = basename($file);

i want determine whether given triangle intersects tetrahedron. not want compute solution polygon(if exists) itself. there library/package/published practical algorithm can used solve problem directly (unlike attempt below)? i think last resort have use standard polygon-polygon intersection algorithm implementations solve problem indirectly . my attempt on problem: thought of breaking problem of polygon-polygon intersection. each triangular face(say t1 ) of tetrahedron , given triangle t2 , thought of doing following: compute intersection(a line) between planes corresponding each triangle, l1 . for each triangle: for each edge of triangle l2 , compute point of intersection p between l1 , l2 . test(maybe using parametric form) of l2 , if point lies on edge l2 . if both triangles t1 , t2 , there exists at least one edge on intersection point p lies, implies triangles(and hence given tetrahedron , triangle t2 ) do intersect. create orthonormal fr...

this question has answer here: fixed position navbar obscures anchors [duplicate] on html page have link like: <a href="/page.htm#something"> the other page (page.htm) looks like: <h1>header</h1> <p>some text</p> <h2 id="something">the header 2</h2> etc. when follow link page.htm#something header2 on top of browser. my wish room abow it, let's 1em or so. of course can use: <a name="something"><br /></a> <h2>the header 2</h2> but that's ugly , needs lot more typing. is there way link positioned lower in webbrowser? <h2 style="padding-top:20px">the header 2</h2> i understood you?

i have had packages in past looping through multiple text files in folder , loading sql server tables. now asked create package loop through multiple excel files in folder , load them sql server table. i went through following steps create package assuming shouldn't different have in other packages loops through multiple flat file. added execute sql task , truncating staging table, simple truncate table statement. added foreach loop container . selected foreach file enumerator , created variable called file_path data type string. added data flow task . added excel data source . , configured excel connection manager selecting 1 'excel' file in destination folder. (at point configured correctly not showing red cross or warring messages.) then selected excel file connection manager , in properties windows under expressions , selected connection string property , used user variable @user::file_path . at point excel data source showing red cross need...

it seems intellij clears tomcat related folders across redeploy/restart. means every time restart tomcat intellij, have re-login our app. is there way persist tomcat sessions across restarts when using within intellij idea? the intellij configuration local tomcat instance has checkbox "preserve sessions across restarts". check that, , sessions should preserved. by way, i've seen number of developers waste lot of time on years messing around tomcat plugins in eclipse , intellij, trying figure out how them work in manner similar production. the easiest answer far use regular tomcat instance, , forego ide integration. 1 easy thing replace this, if using maven (you using build tool, aren't you?) use maven tomcat plugin .

after online example tried following: configuration config = new configuration(); config.set("fs.default.name","cfs://x.x.x.x:9000/"); // actual ip in here config.set("fs.cfs.impl","org.apache.cassandra.hadoop.fs.cassandrafilesystem"); filesystem fs = filesystem.get(config); system.out.println(fs.exists(new path("cfs:///path/to/file"))); but can't find jar containing cassandrafilesystem . wonder if it's old version or something. have cql driver in classpath, i.e., gradle dependency com.datastax.cassandra:cassandra-driver-core:2.0.1 , class cassandrafilesystem not ship artifact. what's idiom check file existence in cfs? using datastax enterprise 4.0.1. edit : clear, problem here seems finding class cassandrafilesystem . can't find anywhere in dse jar although usage documented. deprecated? in other jar besides com.datastax.cassandra:cassandra-driver-core:2.0.1 ? if have maven project add following mav...

i making things happen when app launches. put statement. returns error: extra argument 'boolforkey' in call . i using swift. how fixed? code: if nsuserdefaults.standarduserdefaults(boolforkey: "haslaunchedonce") { //app has launched before } else { nsuserdefaults.standarduserdefaults(setbool: true, forkey: "haslaunchedonce") nsuserdefaults.standarduserdefaults(synchronize) //first time launch } how fixed? it looks call should be: if nsuserdefaults.standarduserdefaults().boolforkey("haslaunchedonce") { that's because objective-c method name -boolforkey: , not -standarduserdefaults:boolforkey: . when translating swift, put first part of method name before left parenthesis, subsequent parts appearing inside parens.

is possible perform regular expression on n-dimension pdl variable? for example can add 100 elements doing $a1 = pdl [1,2]; print $a1 + 100; however if array bunch of strings perform task on. example fails: $a = pdl ['suze','david']; $a =~ s/suze/female/; print $a; not sure if possible, in advance. the point is, pdl perl extension designed scientific , bulk numeric data processing , display. not made string manipulating. when try iterate through piddle: use strict; use warnings; use pdl; $a = pdl ['suze','david']; print $_ . "\n" foreach ($a->list); you get: argument "suze" isn't numeric in subroutine entry @ basic/core/core.pm.pl (i.e. pdl::core.pm) line 1296, <data> line 207. 0 0 argument "david" isn't numeric in subroutine entry @ basic/core/core.pm.pl (i.e. pdl::core.pm) line 1296, <data> line 207. when take deeper pod, find: $a = pdl(scalar|array reference|arr...

we facing record duplication issue has been claimed csrf attack. the scenario admin user logged in application , adding record, data getting saved in database. corresponding post request getting captured , replayed ends adding duplicate records in database. vulnerability allows attacker add 'n' number of duplicate records in database on replay. can called csrf attack? no, not really. if post being captured, looking @ replay attack , wherein legitimate request replayed again. you can defeat replay attacks adding nonce (random value) form, , requiring random value present when post done, invalidating nonce. same technique used foil csrf attacks. however, if attacker can read post data, may have bigger problems. example, capable of capturing admin authentication step, can reveal passwords or other sensitive information. it's possible aren't under attack, , duplicates caused use of either button or page reloads. in case, safest use kind of defens...
