2020-08-06 02:44:18 Let's build a Full-Text Search engine in Go

Full-Text Search (FTS) is a technique for searching text in a collection of documents. A document can refer to a web page, a newspaper article, an email message, or any structured text.

Today we are going to build our own FTS engine. By the end of this post, we'll be able to search across millions of documents in less than a millisecond. We'll start with simple search queries like "give me all documents that contain the word cat" and we'll extend the engine to support more sophisticated boolean queries.

2020-06-17 20:21:25 Wow, after almost a year of silence a new info about generics in Go comes up officially the update brings to us:
- a new, updated design draft;
- an experimental tool to try generics from the draft by yourself;
- and a few lines about what’s going to happen next.

Here I’d like to post a quote from the post and then allow you to read the rest by the link below.

>>>
Introduction
It’s been almost a year since we last wrote about the possibility of adding generics to Go. It’s time for an update.

Updated design
We’ve been continuing to refine the generics design draft. We’ve written a type checker for it: a program that can parse Go code that uses generics as described in the design draft and report any type errors. We’ve written example code. And we’ve collected feedback from many, many people—thanks for providing it!

Based on what we’ve learned, we’re releasing an updated design draft. The biggest change is that we are dropping the idea of contracts. The difference between contracts and interface types was confusing, so we’re eliminating that difference. Type parameters are now constrained by interface types. Interface types are now permitted to include type lists, though only when used as constraints; in the previous design draft type lists were a feature of contracts. More complex cases will use a parameterized interface type.

We hope that people will find this design draft simpler and easier to understand.

2020-04-29 22:14:16 “How We Created a Realtime Patient Monitoring System With Go and Vue in 3 days”

The risk of handling a Covid-19 ward

The deadly virus can infect you with a very small mistake. As healthcare workers, our frontline has to wander around the isolation wards to check vital signs of a patient from time to time. This task involves disposing of the protective gear after a visit. All just to check some reading on a device.

A request from health authorities reached us to develop a remote monitoring system for isolation wards. There are expensive softwares to remotely monitor them. But Sri Lanka might not be that rich to spend such amount of money.

2020-01-29 10:15:19 An overview and first impressions of Go made by an advanced JS engineer

>> As an advanced JavaScript developer, The more I work with JavaScript the more I understand the advantages of a statically typed language.

JavaScript is fascinating but sometimes you want to try something else and broaden your horizon.

This article will be a brain dump of all I’ve learned so far about Google’s Go language (I will update it as I go, pun intended).

I assume you have installed the Go binaries on your computer.
