GoLang: try-catch

Mon, 22 Feb 2021 12:00:00 +0000

GoLang doesn’t have a try and catch like the popular C++ or Java languages, what it has is panic-recover.

Non critical errors are returned as normal values and for the critical ones, panic is used

GoLang: encoding

Sat, 30 Jan 2021 12:00:00 +0000

Package encoding provide capabilities to convert data to and from byte-level and textual representations.

encoding/gob
encoding/json, and
encoding/xml

The gob is Go’s format for serializing and deserializing. The gob was tailored for communicating between two servers written in Go.

Only exported fields are encoded; zero values are not taken into account

Package gob manages streams of gobs – binary values exchanged between an Encoder (transmitter) and a Decoder (receiver).

Format GoB
#

Let’s create a simple Type Blog and we will encode and decode it using the gob format.

Race condition

When two processes are executing concurrently, the exact order of execution of instructions is not deterministic. Without explicit synchronization instructions it is difficult to predict the outcome of these concurrent execution of process.

Dockeriz'd service

Thu, 13 Aug 2020 05:51:34 +0000

Someone asked me to define a simple docker pod for the service I wrote in GOLang here. I completely forgot about it, till today.

So here is my first attempt at getting a docker image for the service.

GOLANG

Go is a powerful yet simple language. The nuances of assembling a workspace, sometimes are overwhelming, yet when it comes to simplicity it is very powerful.

These are some of the helpful links I have used in the past for understanding Go and developing code.

WebService: In golang

Fri, 15 May 2020 11:42:46 +0000

Having practiced creating loads of Console based programs of golang, it is now time to try something new - A Web Service.

In this blog, I will try and create a Web Service (RESTful) that will be built entirely on Go.

GoLang: SmipleCipher v2.0

Tue, 12 May 2020 11:23:34 +0000

So continuing from the last blog where I wrote a crude version of SimpleCipher and was inclined on removing the duplicate code, here I am with the improved version.

Handy links

[fmt](https://golang.org/pkg/fmt/) package
[strings](https://golang.org/pkg/strings/) package.

Defining `types`

While I compiled and unit tested code the general feeling was what can be optimized.

GoLang: SimpleCipher

Mon, 11 May 2020 10:14:20 +0000

Hello back again, Golang is just a new syntax for me. Even though behind the scenes they developers have simplified many things, for a consumer like me writing a program is more about learning the new syntax and getting familiarized with the control and stack.

Say a Number

Sun, 29 Mar 2020 12:00:00 +0000

With the Corona-Lockdown in place “literally”, it was time to squeeze out some me-time to continue the quest for GO-Proficiency.

Sometimes you re-do optimization in your head so many times that it takes a whole day to see through the mistake you are making.

Package String

Sat, 15 Feb 2020 11:40:19 +0000

Just like Java or C++ there are standard libraries (packages) available with golang. The one that you might end up using the most often is strings.

For this blog, I was writing another practice exercise that is meant to count number of words in an input string.

GOLANG: Proteins & RNA

Mon, 10 Feb 2020 15:06:21 +0000

It was an interesting exercise, and I solved in three ways. More details available here @ exercism.io

Introduction
#

RNA can be broken into three nucleotide sequences called codons, and then translated to a polypeptide like so:

Pangram

Thu, 30 Jan 2020 15:59:51 +0000

I wrote my first program for Pangram in JS here and attempted few variations to optimize the readability and execution time. This time the code challenge was in Golang and it was satisfying attempt to do in first try.

House that Jack built.

Funny thing about simple programs is that there are too many optimization options available that never lets you feel content.

So here I am trying to solve another problem from exercism.io which is totally a must visit for anyone who wants to learn and practice.

Last few weeks have been interesting, a new year just embarked, my learning pace slowed down; comparatively due to the festivities and obligations around, but I am still trying to maintain.
