The role of software version control in embedded software development
Published: 2023-01-23 05:00:00

Software version control is a critical aspect of software development, and this is especially true in the context of embedded systems. Embedded software often has strict requirements for reliability and performance, and version control helps developers ensure that these requirements are met by providing a way to track and manage changes to the codebase.

One of the key benefits of version control is that it allows developers to easily track and revert changes to the code. This is particularly important in embedded systems, as even a small change to the code can have unintended consequences and potentially impact the performance or reliability of the system. By using version control, developers can easily identify and revert any changes that cause problems.

In addition to tracking changes, version control also enables developers to collaborate on code development. Multiple developers can work on the same codebase simultaneously, and version control allows them to merge their changes and resolve any conflicts that may arise. This is particularly important in the context of embedded systems, as it can be difficult to coordinate the work of multiple developers on a shared codebase.

Another benefit of version control is that it provides a way to manage different versions of the code. This is useful in the context of embedded systems as it allows developers to maintain different versions of the code for different hardware platforms or product releases. This can help to ensure that the code is optimized for the specific hardware and software requirements of each platform or release.

Overall, software version control is an essential tool in embedded software development, as it enables developers to track and manage changes to the code, collaborate with other developers, and maintain different versions of the code for different hardware platforms or product releases. By using version control, developers can ensure that their code is reliable, efficient, and meets the requirements of the target hardware platform.
The Rise of Microservices
Published: 2023-01-23 04:58:14


Below are few factors due to which microservices rise up

**The increasing complexity of software applications**: As applications have grown in size and complexity, traditional monolithic architectures have become harder to manage and scale. Microservices provide a way to break down large applications into smaller, more manageable components.

**The shift towards cloud computing**: Cloud computing has made it easier to deploy and scale individual services, making it a natural fit for microservices architecture.

**The increased focus on continuous delivery and deployment**: Microservices allow for faster and more frequent releases, as individual services can be deployed independently.

**The emergence of new technologies and practices**: Technologies such as Docker and Kubernetes have made it easier to containerize and manage microservices, while practices such as DevOps and Agile have emphasized the importance of rapid and frequent delivery.

The need for more resilient, scalable and flexible software systems.

As a result, many companies are now adopting microservices as a way to build and deploy software, especially in the context of cloud-native and cloud-based systems.

I built an AI-powered Twitter Bot in 4 hours
Tags: opensource, ai, showdev
Published: 2023-01-23 04:29:59

Coming off a busy day filled with client calls (I am a full-time freelancer / maker), I had a tiny idea: could I get AI to paint scenes from classic books?

I decided to see if it's possible for me to build something small around this idea. I copied a block of text from David Copperfield, pasted it into DALL-E, and found out it didn't work: it needed a more cohesive prompt.

So I put the block on text into GPT-3, and then had it generate the image prompt for me. I then copy-pasted this prompt onto DALL-E, and it worked surprisingly well! ([image](https://twitter.com/pradeepcep/status/1617293100929650688/photo/1))

I thought spinning this into a Twitter bot would be fun, and did just that, while [tweeting](https://twitter.com/pradeepcep/status/1617291769535934464) simultaneously :)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2vvlajy035ivmo1fs5zh.png)

While this is just a fun little experiment, and essentially all I did was glorified plumbing — I know nothing about AI or ML, and this is just me integrating with different APIs — I would be delighted to hear what you think!
What is Java Virtual Machine (JVM)
Published: 2023-01-23 04:15:57

This is the second tutorial of java programming for beginners series, and in this tutorial we are briefly discuss about java virtual machine's working and functionalities and why it is important.

## The Heart of java programming
You may also called the jvm as the heart of java programming.
JVM is responsible for making java protable and universal.

##JVM working
##Step1.
First of all .java file or programme is converted into .class file consisting of byte code instruction by the java compiler.The java compiler remains outside of the jvm.

##step2
Now .class file is given to the jvm. Jvm consist of a module called class loader sub system that performs the below functionalities
  

1. The class loader sub system loads the .class file into memory

2. Then it verifies whether all byte code instructions are proper or not. If it finds any instruction suspicious the eecution is rejected immediately.

3. If the byte instruction are proper,then it assign necessary 
memory to execute the programme.

##Note
This memory is didvided into various parts mention below 
##1.Method area
This memory block stores the class code, code of the methods in java programme and variables.

##2.Heap
This is the area where objects are created.

##3. Pc registers
This registers contain memory address of the insturctions of the methods. if there are 5 methods, 5 pc regiters will be used to trac the instruction of the methods.

This is the breif and short discussion on Java virutal machine(jvm)
stay tuned for our next tutorial on java

Implante o seu ambiente de laboratório kubernetes com k3d
Tags: kubernetes, docker, devops, k3s
Published: 2023-01-23 01:23:24

# Implante o seu ambiente de laboratório

k3d é um pequeno programa feito para executar um cluster K3s  no Docker. O K3s é um projeto Sandbox e uma distribuição Kubernetes leve e certificada pela CNCF. Projetado para ambientes de poucos recursos, o K3s é distribuído como um único binário que usa menos de 512 MB de RAM.

O k3d facilita muito a criação de clusters k3s de um ou vários nós no docker, por exemplo, para desenvolvimento local no Kubernetes.

*Requisitos*
Tenha o docker instalado para poder utilizar o k3d.
O kubectl para interagir com o cluster Kubernetes.

## Instalação via script
```
wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash
```

## Criando um cluster k3s de alta disponibilidade com o k3d
Como as práticas recomendadas de alta disponibilidade do Kubernetes, devemos criar um cluster de alta disponibilidade com pelo menos três nós control plane.

Podemos conseguir isso no k3d em um comando:
```
k3d cluster create --servers 3 --image rancher/k3s:v1.23.15-k3s1-amd64
```

### Aprendendo o comando:
Comando base: k3d cluster create
Opções:
– server 3: solicita que três nós sejam criados.

– image rancher/k3s:v1.19.3-k3s2: especifica a imagem K3S a ser usada.

Agora podemos verificar o que foi criado a partir dos diferentes pontos de vista:
```
kubectl get nodes --output wide
```

# Scale 

Graças ao k3d e ao fato de nosso cluster ser executado em contêineres, podemos simular rapidamente a adição de outro nó control plane ao cluster HA:
```
k3d node create extraCPnode --role=server --image=rancher/k3s:v1.19.3-k3s2
```

## Aprendendo o comando:
Comando base: k3d node create

### Opções:
extraCPnode: nome base que o k3d usará para criar o nome do nó.

role=server: define a função do nó como um control plane.

image rancher/k3s:v1.19.3-k3s2: especifica a imagem K3s a ser usada.

# Limpando os recursos
```
k3d cluster delete
```

Another week has gone by so here is a rundown of my podcasts listenings…

## Hachyderm’s Kris Nova on running a Mastodon Server

[Hanselminutes episode 871](https://hanselminutes.com/872/hachyderms-kris-nova-on-running-a-mastodon-server)

A great chat about how Hachderm grew as people moved from Twitter to Mastodon. You can find me on Hachyderm [https://hachyderm.io/web/@funkysi1701](https://hachyderm.io/web/@funkysi1701) Hachyderm saw amazing growth in a short space of time, so great to hear how that impacted the service, which Kris Nova provides for free in her own time.

## The Shipment

[The Temporal Trek Season 3 episode 58](https://podcasts.apple.com/gb/podcast/the-temporal-trek-podcast-season-3-episode-59-the-shipment/id1499160640?i=1000591042656)

DanDan discuss the season 3 episode The Shipment, which sees Enterprise season 3 back on track, with a proper Star Trek story. But I can’t believe Dan forgot to include the DanDan jingle its why I tune in each week.

## TrekRanks Potpouri

[TrekRanks episode 150](https://www.trekranks.com/trekranks-podcast)

This was a great show celebrating 150 shows, and was a lucky dip into all the 149 topics that have been chosen before. Jim was caught out by the guests this week as they went above and beyond finding answers for all possible shows that could be picked. As always some great picks reminding me why I love the show.

## Troy Hunt’s Weekly Update

[Weekly Update 327](https://www.troyhunt.com/weekly-update-327/)

I like listening to what Troy has been up to in the last week. (I am a bit behind as this show came out at Christmas time) Troy talks about Twitter and Elon Musk, and the LastPass data breach. I am a big fan of 1Password for my password manager but my employer uses LastPass

## Troy Vinson: Learning From the Rackspace Security Breach

[Azure DevOps Podcast Episode 225](https://www.youtube.com/watch?v=MsK5zaUogJ4)

An interesting look at security and the recent rackspace incident. I used to be a big fan of Rackspace but in recent years I have been more interested in cloud offerings like Azure.

## Dr. Gregory Kapfhammer wants to stop flaky tests

[Hanselminutes episode 874](https://hanselminutes.com/874/dr-gregory-kapfhammer-wants-to-stop-flaky-tests)

I am currently looking at fixing some flaky tests on a codebase I am not familiar with so this is a great podcast to listen to. The episode goes through common reactions to flaky tests, why tests get flaky and what to do about them.
7 Ways To Maximise Your Technical Writing Career With ChatGPT
Tags: productivity, career, writing, ai
Published: 2023-01-22 23:49:15

Recently, people have begun to pick on the flaws of ChatGPT to prove that AI is and will not be a substitute for humans' jobs. "Our jobs are safe"; is a typical sentence people use after managing to convince the AI that "1 + 1" is "11" and not "2". Is the AI really convinced that "1 + 1" is "11" and not "2" or is it acting in line with the way it was programmed—"...not to underestimate man's intelligence", as some people would say? That's not for me to decide. Instead of contending imprudently with ChatGPT, you could augment your skills, and possibly get a chance for a promotion or pay raise at your current job, or an awesome offer from another company. 

![Meme for using ChatGPT appropriately](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6mn32l0ag601448yvr5d.jpg)

As a technical writer, here are 7 ways to tap ChatGPT's intelligence to become better skilled. 

- If you are out of ideas for new articles, ask ChatGPT.

![Meme for asking ChatGPT questions](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/v566irbpghu02419vmlu.jpg)
 
- If you have an idea but inadequate information, ask ChatGPT to write the article.  The article will give you an overview good enough to be your starting point. Ensure you do your research as well and do not copy and paste. 
- You may even have an idea and in-depth knowledge of the topic you want to write about but no structural clarity. Tell ChatGPT what you know and ask it to give you a suitable outline for your topic. 

![A sample outline provided by ChatGPT upon request](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2kv68lwrmnejaam658ts.png)

- You may decide to write a series for beginners or advanced programmers on a programming language or concept; ask ChatGPT to structure the series. 
- Do you need a cover image for your article? Tell ChatGPT to make good suggestions for it. It'll give you a list of search keywords related to your article, and even links to where to get them. 
- You want to improve SEO for your articles? Tell ChatGPT to rewrite your article topic and list SEO keywords. 
- What about paraphrasing? ChatGPT does that well. It can even summarise for you. 

Instead of asking questions that add no value to your career, you may turn things around and make ChatGPT a productivity tool. 

Aside from the list here, ChatGPT offers much more benefits for you as a technical writer. Find them out and use them to improve your skills. When you do, kindly return to this post and write your discoveries in the comment section.
