the decorator pattern demonstrates how can extend behaviour of component without modifying underlying implementation. means have 2 components implement same interface. there way register these in autofixture can still refer component polymorphically interface? a code example my meaning. let's assume want decorate icomponent loggingcomponent interface icomponent { void dostuff(); } class component : icomponent { public void dostuff() { // amazing! } } class loggingcomponent : icomponent { private readonly icomponent _component; public loggingcomponent(icomponent component) { _component = component; } public void dostuff() { console.writeline("calling dostuff()"); _component.dostuff(); } } how go both registering loggingcomponent icomponent , creating loggingcomponent without circular dependency? what's alternative registering loggingcomponent way: _fixture.register<

why considered bad practice use prefix increment operator versus postfix operator old compilers? understanding modern compilers optimize old ones not. there particular reason 1 slower other, , reason left optimized in compiled code? if provide other details regarding operators , compilers i'd grateful, thanks, by "old" must mean old. the reason was, in days before real optimization, main system c/unix development pdp-11 , later vax-11. pdp , vax have pre-decrement , post increment addressing modes. movl r0, -(r1) ; decrements r1 4 , move value of r0 location. movl (r1)+, r2 ; move value @ r1 r2 add 4 r1. these c equivalent of *(--a) = b ; b = *(a++) ; in days of little optimization, these mapped underlying assembly instructions. at same time these addressing modes did not exist opposite: movl (r0)-, r1 movl +(r0), r1 therefore, there no hardware mapping *(++a) = b ; b = *(a--) ; the -(rx) , (rx)+ addressing modes made easy im

i using docker-machine google compute engine(gce) run a docker swarm cluster. created swarm 2 nodes ( swnd-01 & swnd-02 ) in cluster. created daemon container this in swarm-manager environment: docker run -d ubuntu /bin/bash docker ps shows container running on swnd-01 . when tried executing command on container using docker exec the error container not running while docker ps shows otherwise. ssh 'ed swnd-01 via docker-machine come know container exited created. tried docker run command inside the swnd-01 still exits. don't understand behavior. any suggestions thankfully received. the reason exits /bin/bash command completes , docker container runs long main process (if run such container -it flags process keep running while terminal attached). as why swarm manager thought container still running, i'm not sure. guess there short delay while swarm updates status of everything.

i have neo4j database nodes following structure [a:article_id] -[r:about_place]-> [l:location] now want find article_id,location pairs location has lots of incoming relationships (say > 4) match ()-[r:about_place]->(n) n,count(r) rel_cnt rel_cnt > 4 return n.name,rel_cnt; this works, list of locations need. but want incomings articles relation also, 5 article ids china has pointing are. something this, match (a)-[r:about_place]->(n) a,n,count(r) rel_cnt rel_cnt > 4 return a.title,n.name,rel_cnt; but returns 0 rows. im guessing because (a,n) combo used in group clause makes count(r) 1 in each row. saw in talk way count(*) clause works default. i think solution chain these results , make new query life of me cant figure out how. ideas or links too. i'm not sure if there's better way this: match ()-[r:about_place]->(n) n, count(r) rel_cnt rel_cnt > 4 match (a)-[r:about_place]->(n) return a.title,n.name,rel_cnt; als
