iTerm2 tricks you might not know 🤩

Shail Bhatt — Thu, 07 May 2020 13:56:49 +0000

What is iTerm2?
iTerm2 is a replacement for Terminal and the successor to iTerm. It works on Macs with macOS 10.12 or newer. iTerm2 brings the terminal into the modern age with features you never knew you always wanted.

Why do you need it?

If you spend a lot of time in a terminal, then you'll appreciate all the little things that add up to a lot. It is free software and you can find the source code on Github.
In most MacOS application you can hold ⌥ button and one of the arrow keys to jump words for faster navigation while editing large blocks of code.
Unfortunately, iTerm2 does not have these shortcuts by default, so having to change an argument in a long command (or correct a typo) can be a case of pressing ← and waiting.

Easiest way to setup KeyBoard Shortcut.

preference -> profile -> keys -> Natural key Editing

List of Keyboard Combination Below.

Action	KeyBoard Combination
Delete word	⌥ + delete
Delete line	⌘ + delete
Move cursor one word left	⌥ + ←
Move cursor one word right	⌥ + →
Move cursor to beginning of line	⌘ + ←
Move cursor to end of line	⌘ + →
Clear Screen	⌘ + k

Reactive Architecture InShort!!

Shail Bhatt — Wed, 22 Apr 2020 18:25:47 +0000

Why Reactive System?

It’s increasingly obvious that the old, linear, three-tier architecture model is obsolete.
- A Gartner Summit track description

What has changed over the time?

Few years ago, large applications had tens of server, seconds of response time, hours of offline maintenance time and gigabytes of data.
Today applications are getting deployed on mobile devices to cloud-based clusters, running thousands of multi-core processors. Modern users expect millisecond response times and 100% uptime. Data is measured in Petabytes.

Current users software demand can not met by yesterday's system architecture.

What is Reactive System?

We have already identified the all necessary aspects of the modern system architecture. We want systems that are Responsive, Resilient, Elastic and Message Driven. We call these Reactive Systems.

Its core meaning has been formalized with the creation of the Reactive Manifesto2 in 2013, when Jonas Bonér collected some of the brightest minds in the distributed and high-performance computing industry – Dave Farley, Roland Kuhn, and Martin Thompson to collaborate and solidify what the core principles were for building reactive applications and systems. The goal was to clarify some of the confusion around reactive and build a strong basis for what would become a viable development style.

Responsiveness means
React to user/client in timely manner ~= real time !

Resilience ~=Stability
Ability to withstand failure

Elastic ~= Scale up(> request traffic) and Scale Down (< request traffic)

Message Driven ~= Asynchronous and non blocking messaging behaviour
