Steve Jobs - The Lost Interview from Daniel Wagner on Vimeo.
##前提
最近MOD送我電影199 偶爾看到.. 覺得實在很棒… (雖然是20年前訪問… 而且結果大家都知道（爆雷))
##內容
完美的創意與完美的產品的差異 — 在於大量完美的工藝
“There is just tremendous amount of craftsmanship in between a great idea and a great product.”
“問題在於優秀的創意到產品之間存在著大量完美的工藝”
“And as you evolve the great idea, it changes and grows, it never comes out like it starts.”
實現創意的過程中…當你了解的越多…想法會變化甚至面目全非．
“Because you learn a lot more, you get into th subtleties, you also find the… There’s tremendous trade-off that you have to make.”
你不得一次次權衡利弊..做出讓步與調整．

Run docker container as default system services
Start docker daemon when ubuntu launch.
Add conf on service as follow
description "cAdvisor"
start on filesystem and started docker
stop on runlevel [!2345]
#respawn
# @see https://github.com/google/cadvisor/blob/master/docs/running.md#standalone
script
docker rm -f cadvisor || true
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=8080:8080 \
--detach=true \
--restart=always \
--name=cadvisor \

end script

ETCD Architecture study.
Some study note about survey how Raft work in ETCD. Something more about official architecture from digging code.
Data storage in etcd/storage/backend. The file structure as follow:
topic/sub_topic/data
Data Exchange type using protobuf with grpc
BTW: NSQ using http.handle. So, no RPC data exchange issue, no protobuf required.
NSQ about how to elimiate SPOF
Refer to slide.
Seems the SPOF means of client side failure handle, not server side. (TBC)
Every server response to dedicate topic (no redudent) (p.22)
Client use this to add more consumer and handle it as load balance. (Refer topology_pattern)
quote: Assuming you have some sort of load balancer in front of these two hosts you can now tolerate any single host failure.
Need more check about this gist about use NSQ on K8s
