@Proton_Pass lemme share xkcd comic too. yes/no questions are needed - log (base 2) (100,000) = 17 bits. now usual word trabador takes 17 bits. tried to introduce minor substitutions (+4 bits). (+1 for cap) 10 digits (log 10 = 3) and 16 sc (log 16 = 4) 17+4+7 = 28 bits and 2^28 combination.

@Proton_Pass c because its just letters, special characters and no numbers a good password must contain a mixture of numbers, special characters and letters

@engrfix1 p = vi = 2.3 kw

Test your electrical knowledge ⚡ If a motor operates at 230 V and draws 10 A, can you calculate its approximate power without using a calculator?

@sonukg4india umm 1 + 1/a + 1/a² + 1/a³ ..... = 2018 subtract 1 1/a + 1/a² + 1/a³ + .... = 2017 1/a ( 1 + 1/a + 1/a² + ...) = 2017 1/a (2018) = 2017 a = 2018/2017 imagining same happens for b, b = 2019/2018 2019/2018 × 2017 / 2018 = 1/2018² (2019 × 2017)~1

@SB434223 @sesigl i am trying to inbox you but I guess your message settings are closed.

Because 9 idle connections doesn’t always mean your request can actually use them Most likely: one request is holding a lock/resource while waiting on the external API. Now every other request piles up behind it: - waiting for the same DB row - transaction lock - synchronized section - connection checkout - or thread pool starvation So technically the pool looks healthy 9 idle, 1 active …but that 1 active connection is blocking progress for everyone else

Two services. One connection pool with max size 10. Service A queries an external API 100 times per second. The pool has 9 connections idle, 1 active. Next request waits 5 seconds before timing out. Why?

@SB434223 @sesigl very nice explanation. Followed you up!
