Living in Seoul (South Korea) is quite expensive if you don't know where to buy things. For most of the stuff you need in your house, you can buy them online (GMarket, Coupbang, 11st etc.) which will give you a lot of discounts. But, if you want to touch the goods before buying them, visiting the Dongmyo Flea Market may be a good option. Locating near the Dongmyo station, Dongmyo Flea Market opens at 2pm on weekdays and 10am on weekends. They close before sundown and on every 2nd and 4th Tuesday. Basically, you can find everything you need from clothes to household goods with the price ranging from 1,000 won to 100,000 won (most of them are cheap). You can even find vinyl records here. Not sure where did he get all these things?

Yesterday, 20 Sep, the Searchlight team had had a virtual PTG on Google HangOut [0] to discuss some topics [1] about the future of Searchlight. The attendees are Zhenyu Zheng (Kevin_Zheng), Thuy Dang (thuydang), and me (dangtrinhnt). We had gone through a couple of topics including: Welcome new member We are very happy to welcome thuydang to the Searchlight team. Review the works so far Most of the bugs and patches have been cleaned up. Some features especially ElasticSearch 5.x support [3] has been added to Searchlight.

For some reasons, I got this error when running the stack.sh script even though I have my local.conf file setup properly (I used the same local.conf for many times) devstack$ ./unstack.sh [Call Trace] ./unstack.sh:33:source /opt/stack/devstack/openrc:27:source /opt/stack/devstack/stackrc:759:die [ERROR] /opt/stack/devstack/stackrc:759 Could not determine host ip address. See local.conf for suggestions on setting HOST_IP. One quick workaround is to set the HOST_IP default value in stackrc: devtack $ nano stackrc ... HOST_IP=${HOST_IP:-<my host ip address>} ... Then stack.sh will run smoothly :)

stress is a command line tool you can use to stress test CPU and Memory in Linux. An example could be: stress --cpu 8

You can use the following to create a small CPU load in a container's bash:  while :; do echo 'Hit CTRL+C'; sleep 1; done

I got this error trying to run the "docker-compose up" command: $ docker-compose up -d                                                                                                            ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?                                                                                                                              If it's...

At the end of the Rocky development cycle of OpenStack, the Technical Committee intended to remove Searchlight [1] and some other projects (e.g. Freezer) from the Governance (OpenStack official projects). The reasons for that are because Searchlight has missed several milestones and lacked communication of the PTLs (Project Technical Lead). I couldn't stand the fact that a pretty cool project would be abandoned so I nominated to be the PTL of Searchlight for the Stein cycle. I hope that I can do something to revive it. Why should Searchlight be revived?  That is the question I tried to answer when decided to take the lead. It's harder and harder for cloud operators to get the information about the resources of other services (e.g Nova Compute, Swift, Cinder etc.) because they evolve very fast and there are more and more resources and APIs are made (Do you hear about the placement API of Nova?). Searchlight is pretty cool in this case because It centralizes all of that inf...

You can use this following command to search and replace a string in multiple text files in Linux: Original string: "Click here for filters." New string: "Click here for filters or full text search." find ./ -type f -exec sed -i 's/"Click here for filters."/"Click here for filters or full text search."/g' {} \;
