i have crated new database scratch , loaded there 1 single type of node. there no relationships. each node has 2 properties. these properties values not null. here math cannot understand in webadmin dashboard. nodes: 19 798 966 properties: 25 440 880 relationships: 0 relationship types :0 i expecting number of properties 19 798 966 x 2 = 39 597 932 however when query database, results are: $ match (n) has(n.woka_id) return count (n); count (n) 19 798 966 and $match (n) has(n.woka_title) return count (n); count (n) 19798966 what wrong here? webadmin doesn't report counts, indeed highest id in use reported. since multiple properties stored internally in same block you'll see misleading numbers there. validate: match (n) has(n.woka_title) , has (n.woka_id) return count(n) == 19798966 should return true .

suppose want communicate b by sending allocate request turn server t1 , relay address , port r1:r1 similarly, b sending allocate request turn server t2, b relay address , port r2:r2 now want send media b, send media r1:r1, r2:r2 destination address, when turn server receives media @ r2:r2, forward b. media transfer in webrtc, forwarded in way or not? if don't know b's relayed transport address, how can reaches b? yes how works if use turn relay. if , b want connect each other, must know each others server reflexive or relay address. applies if , b in separate networks. server reflexive address nats public address gathered through stun server. if don't know of these 2 addresses can't connect each other. if doesn't know b's relayed transport address can connect through server reflexive address. even knowing server reflexive address of each other won't guarantee connection establishment. if 1 of or b behind symmetric nat , other beh

i spent day trying make up, can't.. this problem: i want yes/no alertdialog doesn't disappear on orientation change , decided use dialogfragment . so prepared code , for first use , perfect, if hit button (that should show dialog) once more ( second, third , further times ) dialog doesn't show up! though can see logs makes instances , have no errors, it's there, can't see it! if fold app, or turn off / on screen (i believe it's calling onresume() method) dialogs shows up, of them (depending how time hit button) , seems displaying issue or refreshing problem maybe.. don't know, came here hoping help. about code: i have listview custom adapter , , in adapter have code show alertdialog ( dialogfragment ) - part of imagebutton onclicklistener . the code dialogfragment use: public static class cmydialogfragment extends dialogfragment { public static cmydialogfragment newinstance(int title) { cmydialogfragment frag = new cm

i'm using grunt livereload only. works fine, noticed has high cpu, , when run "--verbose" see it's watching whole "node_modules" folder. so, made research, , tried ignore this. unfortunately, no success. my watch part of "gruntfile.js" is: // watch stuff .. watch: { all: { files: ['!**/node_modules/**', 'js/**/*.js', 'css/**/*.css', 'index.html'], options: { interval: 5007, livereload: true } } }, and i'm saying want grunt watch js, css , index.html file. explicitly added code ignoring "node_modules", still says it's watching , cpu goes around 30%. (mac osx) ================== one thing noticed though: when make change in "gruntfile.js" - example add 1 more file "files" property of "watch" task - restarts grunt, , in console see start watching files want, ,
