IPhone will beat DSLR in long run

I started taking interest in photography recently and have accumulated a decent amount of gear but I am realizing that the ease of taking out your phone and clicking picture will beat the DSLR in long run. A friend recently visited me from NY and we wanted to take a family picture and I was setting up Tripod and Flash and doing settings changes and he was like leave all this, lets take a Selfie and that’s it, in 2 second the picture was done and he shared it on facebook in another 1 second.  Now one can argue that DSLR would have clicked a better picture but DSLR has many things going against it:-
Learning curve : I must have spent 200+hours on reading about photography but still cant take decent pictures as my bar is high. Not everyone is interested in spending this much time.Amount of gear to be carried : On hikes its a pain to carry your DSLR whereas your phone has to be anyway with you.Cognitive effort of tweaking the gear: You have to have a different lens/settings for different s…

Docker Aha moment

I had read many articles about docker before but today was the day when I realized the aha moment.  I had designed database structure of a new application where different micro-services uses their own schemas and each can be located on its own server depending on the scale requirement. Locally I had kept them on same mysql host but on production it will be used on different Google CloudSQL instances.  The aha moment for me was when I was able to fire up multiple mysql containers and map them to a different port and do end to end testing of my sharding code all on local box.

All I had to do was

docker run -p 3306:3306 -d  gcr.io/xx-us/mysql:5.6
docker run -p 3307:3306 -d  gcr.io/xx-us/mysql:5.6
docker run -p 3308:3306 -d  gcr.io/xx-us/mysql:5.6
docker run -p 3309:3306 -d  gcr.io/xx-us/mysql:5.6
docker run -p 3310:3306 -d  gcr.io/xx-us/mysql:5.6
.....

and I had many mysql servers ready to be tested.   In the VM world I would not even had dared to start 5 vm on my laptop.
