在 Arduino IDE 中 ESP32 的 hallRead() 傳回亂數
Tags: esp32, arduino
Published: 2021-06-09 12:19:44

如果你在 Arduino IDE 中開發 ESP32 的程式, 可能會遇到內建的霍爾感測器值亂跳, 根本無法使用的情況, 像是這樣：

![2021-02-02](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/60kuz01ppb4tz5qfgyzf.png)

這很可能是因為 [ESP32 套件版本](https://github.com/espressif/arduino-esp32/issues/4866)的關係：

{% github https://github.com/espressif/arduino-esp32/issues/4866 %}

根據我自己的實測, 在 1.0.4 或更早的版本是沒有問題的, 像是以下的展示影片：

{% youtube MgA_Wok05gI %}

如果使用 1.0.5 或是 1.0.6 就會發生上述的問題。解決方法很簡單, 在沒有修正前, 就是降版本囉。或者, 你也可以自己研究一下原始碼, 找出問題, 回饋社群囉。

補充：經過反映後, 官方回應如下：

I'll fix this in v2.0. For 1.0.x, you can use this:

```C++
#include <driver/adc.h>
void setup() {
  Serial.begin(115200);
}

void loop() {
  Serial.printf("idf read: %d\n", hall_sensor_read());
  delay(100);
}

Então seu cliente desenvolve uma aplicação nota 11 na escala Richter e diz que se ela espirrar ele precisa ficar sabendo, caso contrário a raça humana será extinta ¯\_(ツ)\_/¯

Você pensa em explicar qual seria o impacto negativo de se criar um monitoramento com intervalos tão curtos… até que você lembra do milagroso “Throttling”.

Não se lembra do “Throttling”? Então continua essa leitura que vou te mostrar do que ele é capaz.

Na versão 4.2, junto com outras opções de pré-processamento, foi lançado o Throttling.

Sendo mais claro, seu funcionamento consiste em trabalhar com “descarte” de valores. Isso somado a uma coleta de 1 segundo (por exemplo) faz você se tornar o Thanos do monitoramento.

![](https://cdn-images-1.medium.com/max/887/1*-nBza-pEWGEtZoSIZhMlkg.png)

E não sou eu quem estou falando, olha ai na documentação dizendo: “Zabbix God tools”.

Link da documentação abaixo:

[Zabbix Documentation 5.4](https://www.zabbix.com/documentation/4.2/manual/config/items/item)

Normalmente, se você alterar a coleta para 1 segundo, você teria valores assim:

> 1; 2; 3; 3; 3; 3; 5; 2; 1; 2 …

Com o pré-processamento, sempre que a coleta receber um valor igual ao valor anterior, ele descarta aquele valor, ou seja, não será escrito em banco, e o mantém até que um novo valor ocorra. Dessa forma, o exemplo acima ficaria gravado como:

> 1; 2; 3;;;;5;2;1;2…

Vamos criar um item na prática pra explicar melhor essa dádiva dos deuses.

Criei um item, alterei seu tempo de coleta para 1 segundo e em pré-processamento criei uma regra de Throttling.

![](https://cdn-images-1.medium.com/max/739/1*CQ1mEN0nRnDxqmhXuK_H7A.png)

![](https://cdn-images-1.medium.com/max/835/1*qWF56XqnBRD9nJCvUUCR_Q.png)

Existem duas opções, a “Discard Unchanged” e a “Discard Unchanged with heartbeat”. Observe os valores coletados no item acima:

![](https://cdn-images-1.medium.com/max/198/1*geMcG2uwNfmQd-5vooJ5Mg.png)

> Exemplo configurado com 30sec

A imagem acima se trata da opção “Discard Unchanged with heartbeat” que faz o descarte dos valores somente após o tempo que estipulamos em sua configuração (em segundos). Podendo ser usado nesse campo LLD-macros e macros comuns.

![](https://cdn-images-1.medium.com/max/200/1*st6XrPMCBu9d_m355pmqBg.png)

Já esta outra opção “Discard Unchanged”, como podemos ver, sempre que o valor se mantém ele o descarta até que o próximo seja diferente.

IMPORTANTE: Caso o valor seja descartado, ele não é salvo no banco de dados, sendo assim o Zabbix Server não saberá da existência dele no futuro. Tenha isso em mente caso em algum momento queira criar triggers que se baseiam em valor/tempo, pois sua trigger pode não disparar/resolver corretamente.

Streamlining processes and smart work can help you achieve the holy grail of productivity. Though productivity tools can help you boost productivity at the workplace, it is necessary to think of other ways to boost productivity. An official survey has revealed that 56% of small business owners consider communication is key to boosting productivity. Whether you are a startup owner or running an SME, the most powerful way to boost productivity is to optimize task management system effectively.

It is fair to mention that effective communication and time management can contribute to managing tasks at the workplace. These days, many companies use a robust task management system to achieve this objective.

Better task management can boost the productivity and morale of your team. Here are the top five tips to optimize task management for increasing the productivity of your startup.

Five Tips to Optimize Task Management at Your Workplace
1. Define
The first step for every project or process is to determine why it is necessary to accomplish the project. Once the checklist is created, you can know every task necessary to get the end result. It is necessary to begin task management and come up with a proper strategy to complete the tasks on time. As a project manager, you will have an idea how much time it will take to complete the project after outlining the process. You can also know which tasks you should complete first. You can instruct your team accordingly and manage tasks efficiently as per their priority.

NodeJs Response
Tags: help, node, javascript, webdev
Published: 2021-06-09 11:43:49

Consider a Nodejs express app

I am setting a new parameter 'abc' with a string to the response object

If I send a response to frontend will they be able to view the value of abc 

![Nodejs](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lf75fo9snuq07nlt4inr.jpg)

If you inspect via browser, you will be able to see the 

- Headers
- Cookies
- Response Body
etc

But is there any possibility for the value 'abc' to be got by the frontend ?
FS Blog #3: Course Tracker - My Sinatra Project
Published: 2021-06-09 07:27:51

For my Sinatra project, I'm building Course Tracker, a web application that helps students to manage and track the online courses they are taking. The idea is that the students can use Course Tracker to sign up/create user accounts, log in and log out of their accounts, and can add, edit, and delete the online courses they are taking to their Course Tracker account, including course name, course status, course url, etc. to better manage their online courses and their learning progress.

When users log in to their accounts, they will be able to view all of the online courses that they are tracking at any given time, they then can check each course's status, add new courses, edit or update existing course's name and status, delete courses they are no longer taking, and go to the course websites from their Course Tracker account or course dashboard. 

This is a very simple MVP, built using the knowledge I have learned so far from the curriculum on Sinatra and other topics including ActiveRecord, HTML, CSS, etc. Even though it is a very bare-boned app, I still spend many hours building it, fixing environmental/technical issues, and debugging codes. However, I really enjoyed building it, and it was exciting because it is my first fully-functional web app, and it feels like I was tying together "frontend" and "backend" together for the first time, especially after the first CLI Data Gem project. This is only my second coding project, and there are so many features and improvements I would have liked to have (especially the styling and CSS!), but for now, this is a good start as a basic MVP project. :)

For the project, I used Sinatra, ActiveRecord, Ruby & HTML, Pry, Corneal, and other Ruby Gems.

In the above example, there is a Person class and a Person2 class.  The difference between the two is that Person2 has a default value for the birthday and Person doesn’t.  Easy enough. 🙂

How HR Software assists with your difference, equity, and composition maneuvering
Tags: hr, software
Published: 2021-06-09 10:57:57



Notwithstanding, when thousands of software vendors that were already hard to keep track of all of a sudden start delivering new functionality, it can be a bit hard to keep a record of it all!

Employer Branding:
You can source from DEI focused job boards (FairyGod Boss, Jopwell, etc), build compelling content (landing pages via career site CMS, social posts, email campaigns) from your ERGs to draw and save underrepresented faculty, and build talent funds for future hiring into your 

CRM.Recruiting Process: 
Concentrate on blind resume screening in your ATS, the right language in job descriptions (check out Textio), Rooney rule policies (not HR Tech, but worth a shoutout), and referrals that don’t exacerbate a current DEI problem (like referring like can be a big issue, look for tools that help you source more balanced demographics).

Assessments: 
Skills-based hiring rubrics, algorithmic top of funnel vetting via chatbots, flexible resume requirements in your 

ATS,Scheduling: 
I put this one in here to show the depth that HR Tech can offer...even the right scheduling software can play a major role in DEI by making sure an interview panel is inclusive, flag suboptimal pass rates from specific interviewers (plus provide coaching materials for those who need it!), and flexible interview times.

People Analytics: 
There are of course dashboards to keep track of pay gaps, demographics in different functions/offices/roles, etc.  More interestingly, you can use organizational network analysis (ONA) to do really insightful analysis on career pathing (who in your org are good mentors, why have some women broken the glass ceiling, where are veterans excelling, etc), what story do communication networks in your company tell (segregation, inclusiveness, somewhere in between), which hiring channels are producing results you're after, etc.

Employee Experience: Use a best-of-breed performance management/goals platform to understand how different groups are functioning, employee engagement tools to figure out where strengths and weaknesses are in your culture when it comes to DEI, and coaching platforms to implement just in time education and management where needed.This listing isn’t comprehensive, and there’s a ton of innovation happening in this space.  But, it should give you some places to think about focusing as you look to leverage your existing HR tools to execute your DEI strategy.I also hope it’ll expand your mind a bit when it comes to the many ways tech is helping shape organizations so that the next time you buy software you can dig a little deeper into how that particular tool can help with this oh-so-important goal.

5 Easy TIPS TO BOOST E-COMMERCE CONVERSION RATE USING CHATBOTS
Tags: ecommercechatbots, ecommercedevelopment
Published: 2021-06-09 10:46:25

Ecommerce chatbots are changing the world in the most easiest and efficient way. Whether you know it or not, unknowingly, you probably would’ve exchanged texts with the bot.

Well, we all have.

We are living in an era where you’ll find chatbots everywhere. Chatbots have become the most common feature in eCommerce, Healthcare, Media & Entertainment, SaaS Websites, Lead Generation, etc.

“Chatbots Represent A New Trend In How People Access Information, Make Decisions, And Communicate.- Christie Pits”

Customer service, payments, promotions, technical support, logistics, and market research are all part of the intricate network of operations that take place behind the scenes of every popular online shopping site.

Now, ror generating sales and enhancing customer service, chatbots will almost probably be an element of every successful e-commerce business. According to Insider Intelligence, by 2024, consumer retail usage of chatbots will reach $142 from just $2.8 million in 2019. 

Chatbots are automated bots communicating with clients via a chat interface and providing a comparable experience to conversing with an actual customer service representative. Now that every website has a chatbot, make sure that you make proper use of it because chatbot conversation is important and somehow it will affect your chatbot customer service. A chatbot is used for a variety of applications, but customer service is the most popular. But it’s important to note that not all online chatbots are the same. In general, there are two different types: rule-based bots and machine learning bots. Also, there are many benefits of chatbot in eCommerce that will astonish your very core.

But, first things first! You should understand the conversion rate and how you’ll calculate it.
