answer question wrong has chance deadlock. condition variable - wait/notify race condition i found no solution solving race condition or dead lock issue. imagine have 2 threads. goal follows. first condition: thread 1 waits thread 2 notifies second condition: thread 2 notifies thread 1 should not wait , continue normal execution. how can implemented correctly without having queue notifies? because want part of code run fast possible , use boolean value instead of adding item queue. there 2 threads, use of queue seems overkill me. pseudo code when there race condition: thread 1: lock(x); if(!signaled) { unlock(x); // ******** // still small gap, how avoid? cv.wait(); // forget spurious wakeup sake of simplicity signaled = false; } else // ******** unlock(x); thread 2: lock(x); signaled = true; cv.notify(); unlock(x); now if remove 2 lines commented ******** race condition solved , chance of deadlock introduced thread1 waits while owning lock , t

self signed cert looked down test-only certificate. per understating, using production fine if used right reason. trying provide guidelines customers use what. e.g.: authentication : not ok use self-signed brower not trust "self" issuer. so, service-to-service or service-to-client authentication not ok use self-signed. unless there pre thumbprint/cn whitelisting process before verifying. lot of people these, e.g. azure upload management cert public key, used authenticate api. signing : no ok, there no trust issuer. unless there pre thumbprint whitelisting process before verifying. unless there pre thumbprint/cn whitelisting process before verifying. encryption : ok use self-signed there no chain trust required. in case of attack, mim cert not decrypt, no other impact. i thoughts/recommendations/guidelines community ensure recommendations in right direction. thanks. authentication: not ok use self-signed brower not trust "self" issuer. ok

i have created angular2 component library , linking library main project. when build library, creating build folder, execute npm-link inside build folder, creating node_modules folder packages inside build folder(which should not happen). now when link library main project, getting error, error because of repetation of node_modules twice. (node_modules of main project & node_modules library problem. think there should 1 node_modules of main project.) here steps following link library main project. inside library "npm run build:clean" "npm run build:link" go inside build folder , run "npm link" (at point node_modules created) inside project npm link @nw/ui-vdp ng serve --proxy-config proxy.config.test.json --aot my libraries package.json is "scripts": { "build:ngc": "ngc -p src/tsconfig-ngc.json -w", "build": "npm run build:ngc && npm run copyassets",

the weblogic scripts, i.e., startweblogic.sh, stopweblogic.sh, etc not working command line. doesn't throw error,it doesn't start/stop server. think there might issue environment variables. please let me know if there's way can resolved.

i need modify code have correct values in column j . colored better understanding, rows have same values columns a d in column j want have correct values follows: - if row 6 = row 7 j6 = 2 - if row 8 = row 9 = row 10 j8 = 3 - , on my code not enough, because don't want have red values in column j dim tw worksheet: set tw = thisworkbook.worksheets("stack") dim row integer row = tw.range("b" & rows.count).end(xlup).row lin = 2 until lin = row + 1 nr = 1 while (tw.cells(lin, 1) = tw.cells(lin + nr, 1) , tw.cells(lin, 2) = tw.cells(lin + nr, 2) , tw.cells(lin, 3) = tw.cells(lin + nr, 3) , tw.cells(lin, 4) = tw.cells(lin + nr, 4)) nr = nr + 1 wend if nr = 1 else tw.cells(lin, 10) = nr end if lin = lin + 1 loop

i have rails project using sidekiq. in project, want have multiple sidekiq processes. example, 1 normal sidekiq process (allow many concurrent workers) , 1 synchronous sidekiq process (allow 1 worker). here setting: here normal sidekiq process: --- :logfile: ./log/sidekiq.log :queues: - [important, 4] - [default, 2] - [low, 1] here synchronous sidekiq process: --- :logfile: ./log/sidekiq.log :queues: - long_running i start 2 sidekiq processes using following commands: bundle exec sidekiq -c config/sidekiq.yml -c 4 bundle exec sidekiq -c config/sidekiq_synchronous.yml -c 1 finally here sidekiq configuration in rails: sidekiq.configure_server |config| config.redis = { url: env['redis_url'] } config.on(:startup) scheduled_set = sidekiq::scheduledset.new end end sidekiq.configure_client |config| config.redis = { url: env['redis_url'] } end sidekiq.default_worker_options = { retry: false } it looks sidekiq use sidek

i working on project create multiple chat rooms using react native , firebase. when comes react native, firebase's documentation rather sparse , doesnt have many implementation examples. i have chat works 1 on 1 chat, taken this example. how add functionality add/remove private chat rooms add/remove users to? have tried using firechat api, unfortunately not work react-native. here have far: import firebase 'firebase'; class messagebackend { uid='' messagesref = null; constructor(){ firebase.initializeapp({ apikey: '0000', authdomain: '0000.firebaseapp.com', databaseurl: 'https://0000.firebaseio.com/', storagebucket: '0000.appspot.com', }); firebase.auth().onauthstatechanged((user) => { if (user) { this.setuid(user.uid); }else{ firebase.auth().signinanonymously().catch((error => { alert(error.message); })) } }) }

i installed cassandra https://bitnami.com/stack/cassandra on cloud machine. cloned machine 2 machines. 1 running cassandra server (1 node cassandra cluster) , other acting client , issuing queries first 1 (server). i used ycsb - https://github.com/brianfrankcooper/ycsb perform benchmark. observed read latency on server low few microseconds (around 50/100 99th percentile , max) observed using "nodetool cfhistograms <'db'> <'table'>" , "nodetool cfstats <'db'>" - data coming cache i.e. sstables in cache. but end-to-end latency observed client (other node) ycsb benchmark tests high - average latency = 2000 us. wonder why end-to-end latency high 2000 opposed 100 (on server). network latencies low around 200 (as seen using ping). want cassandra server respond quickly/instantly possible. can help? so start cfhistograms measures local read latency time pull off of memtables merge sstables. not include coordinatio
