Surpresa

Pura verdade.

The nature is perfect.

i'm thinking about how cats hold their babies and how so many mammals also hold their babies and also about how physical touch is a love language

Ooooohh

Vale a pena aprender a programar.

I was asked to make a masterpost on websites like Codecademy, so I’ve tried to compile a list of the best (and mostly free!!). In no particular order: 

1. Codecademy [x]

I couldn’t not include Codecademy! Just in case you haven’t checked it out, it’s pretty neat. It has courses for learning languages and web developer skills.

Languages: Python, Ruby, Java, PHP, jQuery, JavaScript, HTML/CSS

Extras: Git, SQL, Command Line, AngularJS, Ruby on Rails

2. Code School [x]

This is pretty similar to Codecademy with the in-browser coding and such. It also has additional features like teaching videos. A good introduction to programming languages.

Languages: Python, Ruby, Javascript, HTML/CSS

Extra: iOS development with Objective-C or Swift, Git, SQL

3. Learnaroo [x]

Has tutorials followed by mini challenges based on the concepts you’ve just learnt! It also has some reference pages called “Learn x by Example”. Looks pretty good.

Languages: Python, Java, Ruby, HTML/CSS

Extra: Algorithms, Mathematics, + a bunch of premium membership stuff

4. Learn … 

A set of related websites (see below) which have mini tutorials on language concepts followed by mini challenges, similar to Learnaroo.

Languages: Python, Java, C, C#,  JavaScipt, PHP, Shell

5. Code Combat [x]

Basically, it turns learning to code into a game! As you move through the levels, new concepts are introduced, so the code you need to write to play the game gets harder. 

Languages: Python, Java, JavaScript, CoffeeScript, Clojure, Lua

6. Codingame [x]

Similar idea to Code Combat, but a little more advanced. 

Languages: Python, Java, Ruby, C, C++, C#, Haskell, VB … there’s actually loads it supports.

7. Code Wars [x]

This is more for ‘training’ with a language you already know. It offers plenty of practice through challenges, so it’s really good for improving your coding skills. 

Languages: Python, Ruby, Java, C#, Haskell, JavaScript, CoffeeScript, Clojure

8. Coderbyte [x]

This offers some video tutorials and challenges for a few languages, plus special courses on specific algorithms and bootcamp/interview prep. You need a premium membership for quite a lot of things, though (e.g. I don’t think you can watch any of the videos with a free membership).

Languages: Python, Ruby, JavaScript

Extras: Algorithms, Bootcamp Prep, Job Interview Prep

9. Free Code Camp [x]

Mini tutorials followed by mini challenges. Has a number of courses on the languages below!

Languages: HTML/CSS, jQuery, JavaScript

Extras: Git, Algorithms, + a bunch of projects to complete

10. Programmr [x]

Has courses to learn various languages through doing little exercises/challenges in the browser, similar to previous examples. Also has ‘zones’ for more languages, where you can find challenges, example code and projects people have shared. 

Languages: Python, Java, C++, C#, PHP, jQuery

11. CheckIO [x]

Only offers Python, but I still think it’s really great. You move from level to level, getting challenges which are gradually trickier. Learn by doing!

12. Rails for Zombies [x]

For people who already know a bit of Ruby, but nothing about Ruby on Rails!  Each level begins with a short video followed by interactive challenges where you program Rails in the browser.

That’s all (for now!) Hope this is helpful! (ﾉ^∇^)ﾉﾟ

Boa dica.

You never know when info will be removed or changed. Especially if it’s a confirmation page or a receipt or even a job listing description (which they tend to delete before the interviewing phase).

Characteristics and Applications of LoRa Spread Spectrum Modulation SoC Module

LoRa spread spectrum modulation technology, known for its low power consumption and long-distance transmission capabilities, excels in long-range wireless communication. So, what kind of sparks will this modulation technology create when applied to SOC modules? Let's briefly illustrate this with the LoRa-STM32WLE5 LoRa spread spectrum modulation SOC module developed by NiceRF.

The LoRa-STM32WLE5 wireless module  is SOC wireless module the latest  developed by NiceRF Wireless. The LoRa-STM32WLE5 adopts ST's STM32WLE5 chip as the main chip, equipped with a high-performance Arm Cortex-M4 32-bit RISC core, operating at a frequency of up to 48 MHz. supporting 256KB flash memory and 64KB operational memory. This module ensures ample storage and processing capabilities. Additionally, the module is equipped with an industrial-grade crystal oscillator, ensuring stable operation in various working environments. 

In terms of communication technology, the LoRa-STM32WLE5  adopts  LoRa spread spectrum modulation, which features low power consumption and long-distance transmission. This makes the module perform exceptionally well in ultra-long-range wireless communication. It has a high receiving sensitivity of up to -141dBm@BW=125KHz and adjustable transmission power, with a maximum of 22dBm, allowing for transmission distances of over 5000 meters. This characteristic offers extensive application possibilities in fields such as security systems, smart agriculture, and industrial manufacturing. 

In addition to its technical features, the LoRa-STM32WLE5  also has  advantages such as low power consumption, secure encryption, and multiple interface types. Its sleep current is less than 1uA, and its receive current is less than 8mA, making it suitable for scenarios requiring long battery life and high energy efficiency. Additionally, it supports 256-bit hardware encryption and PCROP read/write protection, ensuring data security and integrity. The support for various interface types, including UART, SPI, I2C, GPIO, and ADC, enables it to meet the interface needs of different application scenarios, offering excellent scalability and flexibility.

In terms of applications, the LoRa-STM32WLE5 wireless module can be widely used in security systems, smart agriculture, industrial manufacturing, and smart home scenarios.

For example: in security systems, it can be used for remote monitoring and alarm systems; in smart agriculture, it can be utilized for agricultural environment monitoring and automated irrigation systems;in industrial manufacturing, it can be applied to equipment monitoring and remote control systems; and in smart homes, it can be used for smart door locks and environmental monitoring.

In the future, with the development of IoT technology and the proliferation of intelligent applications, the LoRa-STM32WLE5 wireless module is expected to demonstrate its value in more fields. For instance, in urban smart construction, it can be applied to smart city traffic systems and intelligent energy management. In the industrial IoT sector, it can be used for remote monitoring of industrial equipment and intelligent production lines. Additionally, as technology continues to advance and costs continue to decrease, the LoRa-STM32WLE5 wireless module will become more widespread and mature, bringing more convenience and possibilities to people's lives.
