A handy and powerful library to deal with unstructured data

The below piece of code shows an example of usage

type Person struct {
    Firstname string   `structs:"firstname"`
    Age       int      `structs:"age"`
    Siblings  []Person `structs:"siblings,omitempty"`
}

func main(){

k := knoa.Map().Set("firstname", "John", "age", 20)

k.Set("siblings", []Person{

{

Firstname: "Tim",

Age: 29,

{

Firstname: "Bob",

Age: 40,

})

k.Set("age", 23, "siblings[1].age", 39)

var person Person

k.To(&person)

}

I am working hard to provide a ready-for-production release, but any feedback or suggestion will be appreciated in the meantime!

Embedding. It sure is weird, isn't it? it's unlike traditional inheritance, and it can be uncomfortable at first. But it does have a lot of positives to it that might not be obvious at first. In this talk, we'll go over highlights and pitfalls of embedding, and some interesting ways to use it. 13 points posted by gopher

Video: Complex Concurrency Patterns with Go #golanguk

Thu, 21 Sep 2017 00:48:00 +0000

There is a lot of power available through Go's concurrency primitives, but they are still just that: primitives. Typical examples of channel and goroutine usage show pipelines and worker pools, but real applications are rarely that simple. Production systems can easily end up with hundreds of goroutines running dozens of interdependent functions; reasoning about the resulting interactions is not easy. 13 points posted by gopher

করো: Translating Go to Other (Human) Languages, and Back Again - Golang UK 2017 by Aditya Mukerjee Published August 17, 2017 in Technology

Like most programming languages, Go uses English keywords. But Go's unique approach to byte and string handling makes it the ideal candidate for a universal programming language that can be localized to allow English-speaking and non-English speaking developers to collaborate on the same projects.

go-edlib - Update: Cosine similarity, Fuzzy search, Benchmarks & More! #go #golang #opensource

Thu, 05 Nov 2020 18:12:00 +0000

Go-Edlib is a new open-source library for Golang that implements most popular edit distance algorithms and soon all of them! Currently, it includes: Levenshtein, LCS, Hamming, Damerau-Levenshtein (OSA and Adjacent transpositions algorithms), Jaro/Jaro-Winkler, Cosine similarity.
All these algorithms have been implemented in such a way as to be fully compatible with Unicode

It also includes fuzzy search algorithms based on edit distance and few others string comparisons functions.

I'm actively looking for feedback and/or contributions to improve this library or to have new functionality ideas to add! :)

Backer - docker container backup. #docker #golang #cobra

Wed, 07 Nov 2018 12:14:00 +0000

Motivation

Think about a small company that have to build fast and easy realiable services for a intranet (eg. gitlab, jenkins ...) The fastest way is to deploy this services as a docker containers and manage them for example with a reverse proxy... Taking care about the backup system is an heavvy work, I ended up building this small utility. At this time I only need to do local backups for the active and running containers and their mounted volumes.

info command

I'm not sure about the info command, if it's worth and useful i will do it right :)

Usage

  backer [type] [flags]
  backer [command]

Available Commands:
  help        Help about any command
  info        retrieve informations about backups previously done
  list        list current available backups
  version     shows the version of the executable

Flags:
  -h, --help            help for backer
      --outDir string   output directory for saving backups (default "backup")

Examples

backer

backer full Executes a full backup for all active and running containers.

restore

Usage:
  backer restore [containerName] [revision] [flags]

Examples:
backer restore test 06.11.2018_16.03.48

JOB DESCRIPTION

About GMO GlobalSign Ltd
GlobalSign, founded in 1996, is a provider of identity services for the Internet of Everything (IoE), mediating trust to enable safe commerce, communications, content delivery and community interactions for billions of online transactions occurring around the world at every moment. Its identity and access management portfolio, acquired from Ubisecure in September 2014, includes access control, single sign-on (SSO), federation and delegation services to help organizations and service providers create new business models for customer and partner interactions. The former Ubisecure operation is now the GlobalSign Center of Excellence for IAM, located in Helsinki, Finland. GlobalSign’s solutions are designed to address the massive scalability demanded by the emerging $14.4 trillion IoE market, where the ability to make secure networked connections among people, processes, data and things, will require that every “thing” have a trusted identity that can be managed. The company has offices in the U.S., Europe and throughout Asia. For the latest news on GlobalSign, visit www.globalsign.com or follow GlobalSign on Twitter (@globalsign ).

GMO Internet Group

GMO Internet Group is an Internet services industry leader, developing and operating Japan’s most widely used domain, hosting & cloud, ecommerce, security, and payment solutions. The Group also comprises the world’s largest online FX trading platform, as well as online advertising, Internet media, and mobile entertainment products. GMO Internet, Inc. (TSE: 9449) is headquartered in Tokyo, Japan. For more information please visit http://www.gmo.jp/en/.

We are looking for talented backend software engineers with the right to work in the UK to join our Western hemisphere technical team based in central London. The role allows for occasional working from home but we are principally looking for somebody willing to live and work in London.

Our goal is creating new platforms exposing RESTful services to the IoE/M2M industry, capitalizing on our experience and digital real estate from the SSL and PKI spaces. We have already built a game changing system and are now looking at augmenting it both performance and feature-wise.

On a day to day basis you will be creating new high performance platforms for both internal and external use exposed in a RESTful fashion and backed by large SQL and NoSQL data stores. Part of this will include prototyping new technologies, interacting with PKI/crypto hardware, and shaving off microseconds wherever possible.

We would love to have a chat if any of the following apply:

You write clean, concise, self-documenting code that both you and your team can still understand a year after. You care about naming. You do not repeat yourself. You do not believe that more code represents the solution to a problem. You test everything.
You already master a few programming languages, or easily find your way around a new one. Our stack is mostly Go, but when there are better tools implemented in different languages, we do not hesitate to use and improve them.
You have a high performance systems background - content delivery, trading, networking, e-commerce, ticketing, etc. Everything we build has hard performance requirements. Relying entirely on the language/framework for optimisation is a luxury we do not have.
You have a good grasp of operating systems, knowing how to directly use (or misuse) the scheduling, network and storage facilities.
You think in patterns. Synchronous/asynchronous. Multithreaded/event driven. Latency/bandwidth. You take these into consideration before laying down any code.
You are familiar with the latest technologies and use them judiciously. Software advancements have made things that were impossible ten years ago possible, but no single piece of technology has been a silver bullet. You can tell which of the modern tools in your belt work for the task at hand and which do not.
You know what you do not know and you are as comfortable asking for help as you are offering it. We advocate mutual knowledge sharing. Nobody knows everything.
You know when to work hard and when to kick back. Development effort is not evenly distributed. Sometimes you might have to put in some unplanned extra hours, sometimes you go on a team night out before the clock hits six.
You are an inquisitive perfectionist. You like to know how things work and constantly try to improve them.

What we offer:

The opportunity to work for a leading multinational PKI provider, alongside seasoned technologists with quite a few successful products and services under their belts.
A clean slate. No legacy or poorly documented code to maintain. It all happens here and now with you as an instrumental part of it.
A friendly working environment where we appreciate witty banter without falling into the “brogrammer” stereotype. We are a large and well established multinational company, but this team operates like a start-up where everyone carries their own weight and manages their own time.
Competitive Salary
Employer matched pension contributions to 5% of salary
4 x Salary Life cover
Long-term illness insurance
Cycle to Work Scheme
Employee funded via salary sacrifice Benenden Healthcare cover
Childcare Voucher Scheme
Payroll Giving
