The "hot desking" that comes back will change your office
Tags: hotdesking, productivity, flexibility, workstations
Published: 2021-04-21 10:30:39

From one side, hot desking can save billions of dollars in wasted office space and drive innovation. If you look from the other, the staff is not calm down, you also decrease productivity. However, there are ways in which this is not the case. Like the office space where <a href="https://www.deskflex.com/">hot-desking</a> is very common, the theory behind it is flexibility.
 
<h2>What is Hot Desking?</h2>

Hot desking is simply sharing your workstation with everyone. These workspaces can be used by any employee on any day, regardless of department or position.
Initially, however, it was considered only part of Erik Veldhoen's theory of activity-based working. This theory suggests that the number of workstations in an office suite will decrease, while the variety of spaces will increase, resulting in diversified work styles.

<h2>What kind of effect does it have?</h2>

The theory is that not everyone needs a desk every day. And if your employees aren't in the same seat every day, you won't pile up junk on your desk. It also gives you more opportunities to talk to many colleagues, which gives you new ideas.
Companies, where mobile workers work flextime, have benefits such as facilitating innovation. However, it may not be suitable for the same team to complete routine work with fixed hours from 9 am to 5 pm.
For employees who need a desk or PC, "hot desking" is done with fewer employees than employees. It helps reduce overhead costs but can cause productivity problems if you don't have enough PCs.
"Hot Desking" is a method of keeping the number of PCs used less than the number of employees. The number of desks may also be less than the number of employees.

The roots of hot desking are in military practices called "hot racking" and "hot banking." Soldiers who have finished their duty or shift sleep in the warm beds of soldiers who have just taken turns on the shift. In the 1980s, when PCs were very expensive, hot-desking was first introduced to businesses, inspired by that idea. The idea was to reduce costs by allowing users to share their PCs. But over time, this technique has become completely obsolete. This is because the PC has become a commodity.
Coworking and placement in office space.

Hot desking can be used even more widely if it is placed in only part of the office space. For example, if you have a satellite office with a large number of temporary staff, it is useful to dedicate a portion of the space to hot-desking and a separate meeting room and temporary space to be used only when needed.

Recently, due to the increase in coworking spaces, flexible workspaces are also on the rise. Shared offices also serve the purpose of facilitating the sharing of ideas not only within the company but also among multiple companies, expanding connections and getting people to know their faces. These can also be combined with subscription services that allow workstations and conference rooms for rent in coworking spaces around the world.
A job board that only accepts jobs that are 100% remote

Published: 2021-04-21 10:39:33

I'm [Luc](https://www.linkedin.com/in/lucas-mengel/). I've launched [Remotewx](https://remotewx.com) 🚀

Remotewx is a remote job board on the web to help you find a career where you can work remotely from anywhere. We only accept listings for job positions that are 100% remote. Most of the companies we share are distributed or remote-first companies.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0fmx222l746zlq8id96a.jpg)

Now you may ask: "Does the world need another job board?" I completely agree with you 🙏 . But many of my friends are still unable to find a remote job. Why? It is because, many job boards do not differentiate between covid-remote and full time remote. A company that is fully distributed from the ground up is not the same as a company that offers work from home during covid.
At remotewx - We have a lot of ❤️‍🔥 for companies that are completely remote.

Best,
Luc from remotewx
aws codebuild continues on failure
Tags: aws, codebuild, codepipeline, devops
Published: 2021-04-21 10:32:51

Suppose you have some buildspec.yml file like this that build your project and upload it on some where :
  ```
build:
     commands:
       - ng build --configuration=$BUILD_ENV  
post_build:
     commands:
       - aws s3 rm s3://$ENV_BUCKET  --recursive
       - aws s3 cp dist s3://$ENV_BUCKET  --recursive
```
the Problem here is that if build step fails codebuild continue and  *post_build* will be executed and `aws s3 rm ` will clean your bucket !

I had this issue in my aws codepipeline project (fortunately none-production env) and tried to fixing it.

So here is workaround:
`on-failure: ABORT`
just put in build step  . i tried it and it works like a charm !
 ```
build:
     on-failure: ABORT
     commands:
       - ng build --configuration=$BUILD_ENV  
post_build:
     commands:
       - aws s3 rm s3://$ENV_BUCKET  --recursive
       - aws s3 cp dist s3://$ENV_BUCKET  --recursive
```
Second solution is to add another Deploy Stage in aws code pipeline and do deploy action (cp to s3 bucket ) at there .
Let your code talk..!

Hi there,

Hope you all are doing good..!!

So here is something that I would like to share. I came across the most basic thing i.e 'The importance of Comments in our code'. 
I am creating a sync drive custom logical implementation with laravel and vuejs. When it all started my thought was that once the connection part is successful it will be the easy road to the end. 
Nope here is the unexpected turn, The folder structure includes multiple dynamic folders and sub-folders creations with multiple security data checkpoints then comes the upload part with the right dynamically selected folder.
It started with 4-6-8 and so on conditions, from if to foreach to if-else to else-else-else...
It was getting complicated after every condition, every checkpoint addition it was tough to keep track of all previous ones if about code is not mentioned. To keep track I started placing one-liners /* */ tho, algo was helping but the code complexity was a major throwback. At this point, the comments helped me not only to keep track of my previous checkpoints but with optimization as well. 

We have a practice writing about our code above func and class. I never realized that comments play such an important role till today. It not only helped me know my code better but even my friend got a friendly connection with my code. I don't have to be the middleware between them everything was easy and understandable which was the best part.

Ya, it's gonna help me later as you know na computer memory storage is more than us human.

So guys, Let your code talk it's much more effective..!

Cya another time:)
How To Use LinkedIn Live Streaming Feature To Enhance Business Page Presence - eGoodMedia
Published: 2021-04-21 10:07:03

If you want your live stream to have maximum viewers then try to get the maximum users to follow your profile. You can invite them to follow your page and profile. Once they start following you then they will automatically get notification whenever you go live from your profile. 
 
You can also schedule your post before going live with all the details about your live stream including guest speaker details (tag them in the post) and hashtags. 

Make sure the hashtag you are using is topic-relevant and don’t forget to include #linkedin live in your post. Many times random users use these types of hashtags to find upcoming live stream details. 
 
In the early stage if you are not getting many viewers then we recommend recording your live stream and post it on your feed to let users know what type of topic you discuss in your live chat and how it can benefit them.

Announcing: new and light state manager “Jon”
Tags: react, javascript, state, design
Published: 2021-04-21 10:03:33

## Introduction
So I started using the native REACT methods [REDUCER](https://it.reactjs.org/docs/hooks-reference.html#usereducer) and [PROVIDERS](https://it.reactjs.org/docs/hooks-reference.html#usecontext) for state management
... eventually I ended up with a light lib inspired by [VUEX](https://vuex.vuejs.org/)!
The great thing about VUEX (or FLUX) is that you have a solid structure:
The `State` is immutable,
The `Actions` change the` State`,
The `View` intercepts the` State` changes and calls the `Actions`.
Explicitly expressed by a simple object:
```js
const store = {
	state: { ... },
	getters: { ... },
	actions: { ... },
	mutators: { ... },
}
```
The idea is of a "single source of truth" so I didn't use classes (which if I'm an OOP enthusiast)
as close as possible to REACT

I was surprised how useful it was in my projects so I decided to "publish" it:
[Jon](https://github.com/priolo/jon)
I also made a template:
[SPA-Template](https://github.com/priolo/jon-template)

## Simple DEMO

### Installation
`npm install @priolo/jon`

### Create the store:
`my_app/myStore.js`
```jsx
export default {
	state: {
		value: "init value",
	},
	getters: {
		getUppercase: (state) => state.value.toUpperCase(),
	},
	actions: {
		addAtEnd: (state, char, store) => {
			store.setValue(state.value + char)
		}
	},
	mutators: {
		setValue: (state, value) => ({value})
	}
}
```

### Create PROVIDER
`my_app/index.js`
```jsx
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";

import { MultiStoreProvider } from '@priolo/jon';
import myStore from "./myStore"


const rootElement = document.getElementById("root");
ReactDOM.render(
  <MultiStoreProvider setups={{myStore}}>
    <App />
  </MultiStoreProvider>,
  rootElement
);
```

### Use STORE
`my_app/App.js`
```jsx
import { useStore } from "@priolo/jon";
import React from "react";

export default function App() {
  const { state, setValue, addAtEnd, getUppercase } = useStore("myStore")
  const handleClickIncrement = e => addAtEnd("!")

  return (<div>

      <h1>{state.value}</h1><h2>{getUppercase()}</h2>

      <input 
        value={state.value}
        onChange={(e)=>setValue(e.target.value)} 
      />

      <button 
        onClick={handleClickIncrement}
      >add !</button>

  </div>);
}
```

[sandbox](https://codesandbox.io/s/exe-3-y2ygx)

## Conclusion
The demo is very simple, but I've used Jon on fairly large projects and haven't regretted it.
Furthermore, they are simple PROVIDERS so for debugging you can use REACT Tool:

Download SharePoint Server Recovery Software to repair all corrupt SharePoint Server MDF database files quickly and safely. As an user, I would give this tool a 4.5/5 rating. It recovers Sharepoint database files quickly, effectively, and precisely. 

Our software has dual recovery capabilities, allowing users to restore both SharePoint Server MDF and SQL Database files. Our SharePoint Server Recovery software works for all versions of Windows and restores all forms of SharePoint and SQL Server saved data, including Views, Programmability, and Tables. I recommend that you first evaluate the software's functionality using the free demo edition.

Continuous Integration with Aerospike on GitHub
Tags: aerospike, github, ci
Published: 2021-04-21 09:54:36

[Aerospike](https://www.aerospike.com/) is a highly available and scalable NoSQL distributed database used in production to provide blazingly fast performance at a Petabyte scale.

As a software engineer developing with Aerospike, you probably needed integration tests, and you already have your own way to set up an Aerospike cluster for this.

In this short post I will show you how to add an Aerospike server to your development workflows using the [GitHub Action](https://github.com/marketplace/actions/set-up-aerospike-database) in seconds.

As a GitHub user, you may already know what GitHub actions are. They were [launched](https://github.blog/2018-10-16-future-of-software/) in late 2018 and set a new standard for CI/CD on GitHub.

## Getting Started

The first thing you need is to have your repository hosted on GitHub. Better understand the [GitHub Actions](https://docs.github.com/en/actions) if you’re new to them.

My Aerospike GitHub action repository is [here](https://github.com/reugn/github-action-aerospike), and it is also [published](https://github.com/marketplace/actions/set-up-aerospike-database) on the GitHub marketplace.

Now what’s left is to see some

## Usage examples

You can set up either Aerospike Community Edition or Enterprise Edition. What makes the difference is the `feature-key-file` parameter. Specify it to have an Aerospike Server Enterprise Edition.

### Aerospike Community Edition

To set up an Aerospike Community Edition server with the default configuration

```yml
- name: Set up Aerospike Database
  uses: reugn/github-action-aerospike@v1
```

### Aerospike Enterprise Edition

To set up an Aerospike Enterprise Edition server by specifying the port, the server configuration and the feature key files

```yml
- name: Set up Aerospike Database
  uses: reugn/github-action-aerospike@v1
  with:
    port: 3300
    config-file: '.github/aerospike/aerospike.conf'
    feature-key-file: '.github/aerospike/features.conf'
```

Make sure to commit the configuration and the feature key files in your repository and provide the path, they must be in the same directory.

Now you have your Aerospike server running on Docker and ready for integration tests.

A complete list of supported inputs is available [here](https://github.com/reugn/github-action-aerospike#inputs).

That was fast as I promised. Both the read and the setup. Hope you found this useful, and don’t forget to subscribe to our [newsletter](https://www.aerospike.com/forms/subscribe-the-aerospike-standup/) to get updated with Aerospike weekly news.
