4 cách hướng dẫn sử dụng máy bộ đàm chuẩn nhất 2020
Published: 2020-09-01 06:58:25


1.    Tắt và mở máy bộ đàm
Nút tắt - mở máy thường là nút vặn nằm trên đầu máy, thông thường đây cũng là nút dùng để tùy chỉnh âm thanh lớn nhỏ của máy bộ đàm cầm tay.
Đối với các loại máy bộ đàm cầm tay có bàn phím trước máy, nút tắt mở nguồn có thể được tích hợp bằng một nút bấm ở trên bàn phím của máy. Nút tăng chỉnh âm thanh thường nằm bên cạnh của máy.

Những điều cần chú ý khi tắt mở nguồn:
-         Phải lắp pin vào máy đúng theo hướng dẫn sử dụng
-         Pin phải được sạc điện đầy đủ theo hướng dẫn sử dụng

2.    Tùy chọn kênh liên lạc
Các máy bộ đàm có thể liên lạc được với nhau là do chúng ở cùng một kênh liên lạc. Để tùy chọn kênh liên lạc thì các bạn thực hiện bằng thao tác xoay nút chuyển kênh nằm trên đầu máy, kế bên nút nguồn và điều chỉnh âm thanh.
Còn đối với loại máy bộ đàm cầm tay có bàn phím ở phía trước thì các bạn chuyển kênh bằng 2 nút bấm (^ ˅ hoặc ↑↓) nằm ở phía trước máy.

4 MEỌ NHỎ HƯỚNG DẪN SỬ DỤNG BỘ ĐÀM ĐÚNG CÁCH

Những điều cần chú ý khi chọn kênh liên lạc:
-         Cài đặt tần số sử dụng phù hợp cho máy bộ đàm motorola
-         Kênh liên lạc theo nhóm phải được tùy chọn theo đúng quy định

3.    Thao tác liên lạc qua máy bộ đàm
Trên tất cả các máy bộ đàm cầm tay đều có nút Push to talk (PPT) – nút lớn nằm phía bên trái của máy. Khi muốn liên lạc với các máy bộ đàm khác bạn cần nhấn và giữ nút PPT này trước và trong quá trình nói chuyện, sau khi nói xong thì thả nút PPT ra để nghe phản hồi từ bộ đàm khác.
Những điều cần chú ý khi liên lạc qua máy bộ đàm
-         Chỉ được thực hiện cuộc gọi khi máy có anten
-         Không nên liên lạc khi máy đang sạc hoặc pin yếu
Vì những điều trên có thể gây ra tình trạng hỏng máy hoặc giảm chất lượng máy khi sử dụng.

4.    Sạc pin bộ đàm điện thoại motorola
Cũng giống như những thiết bị điện tử khác, để pin bộ đàm không bị chai thì các bạn cần phải sạc thật đầy trước khi sử dụng đối với máy bộ đàm mới hoặc pin mới mua. Đồng thời nên sử dụng hết pin rồi mới bắt đầu sạc pin lại cho bộ đàm Motorola.

Virtual Dedicated Server (VDS) hosting solutions
Amber IT is introducing Virtual Dedicated Server (VDS)! Powerful instances with quick provisioning were the #1 feature request from our customers. It’s a perfect combination of dedicated physical CPU cores and quick provisioning.

The Power Of A Dedicated Server Provisioned As Quickly As A VPS

With a Virtual Dedicated Server, you get dedicated computing power in the form of dedicated physical CPU cores, which aren’t shared with anyone else, thus there are no noisy neighbors and no one can impact even the most demanding workflow. Additionally, quick provisioning makes these powerful instances available within minutes, not days.

Memory-Optimized

Furthermore, our new VDS series has been specifically optimized for memory-intensive applications such as databases. The 1:8 CPU core to RAM ratio and 100% NVMe SSD storage ensures high performance for all the applications you run on your VDS.

Best-in-class CPU

When choosing a CPU for Virtual Dedicated Servers we wanted to offer as much computing power as possible for as little as possible. That’s why we have chosen AMD EPYC 7282 CPU.

Nested Virtualization

With our new VDS, you can host your own virtual machines. We know that lack of this possibility for VPS has been a concern for many of you, so we have configured Virtual Dedicated Servers in a way that enables nested virtualization!

Dedicated Bandwidth

It’s not only CPU cores and RAM which can be dedicated. You can also order dedicated bandwidth for each of your Virtual Dedicated Servers.

Additional Storage

Should you need more space on your VDS, you can order up to 2 additional disks with up to 4 TB space each!

Equipped with 100% NVMe SSDs, dedicated physical cores, and a sizable amount of RAM our Virtual Dedicated Servers are instantly available for heavy lifting without “breaking a sweat”. Here’s the full Virtual Dedicated Server product line presentation.

Software development is one of the toughest professions to take up. Not necessarily because you have to internalize a lot of complex concepts or algorithms as most people think. This is mostly because of how challenging it is to stay disciplined, it can be a very tough one for lazy developers like me. As a developer, you learn a lot along the way and sometimes get to forget the majority of what you did previously in your code especially when you do not follow best practices like the ones below:
i. Commenting your code
ii. Using descriptive words for variables and function names
iii. Ensuring your function does only one thing
iv. Write unit tests
v. And some other language-specific best practices like using arrow functions for improved code readability in Javascript.

You know challenging it is to find information on a specific technology you are working on, sometimes Stackoverflow fails.

FrontEnd Roadmap
Published: 2020-09-01 05:43:53

**Where to start our career as a web developer or full stack developer?**

No worry about it, i am here to clear all your questions within few minutes. Let’s get started.

So if you are a beginner who don’t know anything what to do to get a job or earning source as a web developer, i recommend you to go with either ui/ux designes or with *HTML/CSS/Javascript*.

If you selected *HTML/CSS/Javascript*, welcome we are same bro!

It takes approximately 2 weeks to get familiar with HTML, 2 weeks for CSS, and 3 weeks for Javascript there after practice to designe sample websites (or try to clone your favorite one) when you feel friendly with HTML/CSS with basic Javascript, jump immediately to Bootstrap for rapid and responsive development. One thing here to keep in mind that always focus on responsive designes even if you are developing a single page with a bit content, make it responsive and test it on different devices. 

When you get enough knowledge about *HTML, CSS, Javascript*, Bootstrap try applying for internship at startup companies, this will gives you a real life experience

**and BOOM !!
you have tag of frontend developer.**

sounds nice right?, but it’s not end here you have to learn any frontend framework/library too it may be *Angular, React, Vue* or any other one. Again if you are asking it to me - which one to choose from above. I highly recommend you to go with ReactJs, because it’s trendy and friendly also it have a huge community supports.

That’s all buddies
Happy Developing

First Post: My Road in Computer Science
Tags: python, beginners, datascience
Published: 2020-09-01 05:28:57

It has been a long time coming and I have finally gathered the motivation to write my first post. Since this is my first blog post I guess I need to give some context of who I am and why I'm writing this. 

#About Me:
My name is Brett Hammit and at the time I'm writing this I'm 21 years old and in my third year of college. I am a Computer Science Major at Abilene Christian University and play baseball as well. This blog is primarily going to just be somewhere that I can give updates on my journey in Computer Science and a place I can share projects and things that interest me.

#So Far in Computer Science:
I wrote my first ("Hello World") in Python about 2 years ago and found just a bit of interest in programming. I had no idea what I wanted to do with it or even if I wanted to work in that line, but it was just kinda something that I knew that I liked doing. Over the 2 years that have transpired I wanted to go into school for Computer Science, but was told that the degree would be too hard for a Division 1 athlete to balance, so I went into a Business Major. After my first year of business classes, I felt that I just wasn't in any classes that truly interested me. During the time  I was doing these business classes I was teaching myself Python by online courses here and there. After the year was over I realized  I wanted to do what I was passionate about and go to school for Computer Science even if it meant challenging myself and pushing things to the edge. Life happened, and I ended up transferring to a 2 year college for baseball, but officially changed my major to Computer Science and could only take a limited amount of CS classes that were offered there. This was just another speed bump in my journey through programming. I was not going to let any of these obstacles prevent me from doing what I wanted to do.

{% twitter 1241899884241969157 %}

#Moving Forward:
Fast forward to today I am now at another 4 year university and taking CS courses this year and pursuing my degree in Computer Science. It feels like a weight has been lifted off my shoulders now that I am finally able to be going to school and excited about what I am getting to learn about for the day. My current interests I am chasing right now is getting into Data Science through Python as I continue to work my way through other CS topics to see what else I am curious to learn about. The purpose of this blog or whatever it may be is just somewhere I can share my projects or things that I'm learning about that I want to share with people. My advice to anyone that is reading this is that even if people try to steer you away from Computer Science or say it will be too hard for you; go for it if you're passionate about it. This has been a long time coming and I'm looking forward to writing more here!

<p>This Multi State button is perfect to toggle through a limited set of modes as needs little space and avoids distracting popups or panels. The satisfying toggle is quite addictive.</p>

<p>All you need is a handful of div elements and include a tiny but of javascript and CSS in your project.</p>

<p>You can style this any way you want. The control is fully responsive.</p>

<p>although there are 4 sides to this 3D control, you can have as few or as many options as you want.</p>

<p>Even the shade changes as the light angle changes on the surfaces. I can't wait to see what a more artistic designer can do with these.</p>

<p>Even though it looks like a cube, there are only ever two div's being animated. No point to mess around with elements you can't see.</p>

<p>optional element attributes:
list - References the ID of a datalist 
direction - defines rotation direction "up", "down,""left" or "right"
shading - defines in % how much % the base color is made lighter and darker as the cube rotates (Default is 60%)
time - time it takes for a 90 degree turn. Expressed in ms. Default is 300ms.</p>

The bane of every developer; spelling, casing, and random commas
Tags: javascript, opensource, python, vue
Published: 2020-09-01 04:36:40

I was recently playing [Twilio Quest](https://www.twilio.com/quest) over on my [Twitch channel](https:twitch.tv/MishManners). Twilio Quest is a coding game where you can learn to program Python, JavaScript, PHP, and more. There's a few modules on open source, as well as how to use the Twilio API.

As I've been learning to code various languages, I've released one very important lesson. Coding is as much about recognising spelling errors, semi-colons, and letter casing as it is about the language itself. Call it the syntax if you will. One small comma out of place can mean the difference between your website loading blank, or working completely. Check out my [Vue JS stream](https://www.twitch.tv/videos/721667385) for a classic example of this in action. But the better example is the clip above where I was doing Twilio Quest.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/5a0fxopksynkftqltkv9.PNG)

## Syntax is highly important

In this short snippet, I had spent over an hour trying to fix this JavaScript code. I was coding it live on stream and many senior developers had looked over the code and couldn't find what was wrong either. 30 devs, lots of experience, and no one could figure it out. Until someone said... "ummm, I think you have a lower case 'l' when it should be upper case 'L'". I was like "ahhh okay"; thinking that totally can't be a thing.

But it totally was a thing. Changing one tiny little piece of syntax was the difference between my code working, and it totally breaking. There's been lots of examples of this over on my live streams. A missing semi colon, a rogue comma, or simply a spelling mistake. I will probably never get used to it, but the one thing I do love... is working it all out.

I was so happy when the code (after an hour of trying) finally worked. At this point I felt like a real developer! It's the small things in life right? If you want to watch the full Twilio Quest stream [check it out](https://www.twitch.tv/videos/638788902). You can play Twilio Quest for yourself too and learn the ways of the Pythonic Temple, or be a JavaScript boss. And if you want to see the full code, check out [my GitHub repo](https://github.com/MishManners/Twilio-Quest-JavaScript).

Oh and if you're wondering why I was wearing a unicorn onesie, it's because we raised over $2000 USD for the kids of St Jude throughout their charity campaign. So I was stuck being a coding unicorn for about a whole month.

Effective Java! Consistently Use the Override Annotation

title: Effective Java! Consistently Use the Override Annotation
published: true
description: A dive into chapter 39 of Effective Java
tags: java, effective, annotation, architecture
series: Effective Java Review
canonical_url: https://blog.scaledcode.com/blog/effective-java/effective_java_use_override/
---

In our previous chapter we discussed creating annotations which was a lot of fun but not something that a lot of developers will find themselves doing on a day-to-day basis. Today we discuss something that you will interact with much more often. That is the `@Override` annotation. This annotation is quite simple but will help avoid some bugs and push detection of some of our defects to compile-time versus later in the process. To illustrate the point let us consider the following example:

```java
public class Bigram {
  private final char first;
  private final char second;

  public Bigram(char first, char second) {
    this.first = first;
    this.second = second;
  }

  public boolean equals(Bigram b) {
    return b.first == first && b.second == second;
  }

  public hashcode() {
    return 31 * first + second;
  }

  public static void main(String[] args) {
    Set<Bigram> s = new HashSet<>();
    for (int i = 0; i < 10; i++) {
      for (char ch = 'a'; ch <= 'z'; ch++) {
        s.add(new Bigram(ch, ch));
      }
    }
    System.out.println(s.size());
  }
}
```

This code loops through the lowercase alphabet and adds two of the same character as `Bigram` to a set. It repeats this operation ten times. Seeing as it's doing the same thing over and over and putting the results in the set and duplicates can't be put into a set you would likely expect the size to be 26 but it actually ends up with 260 elements. Can you spot why the duplicates were allowed to be inserted? The author of this code surely intended to override the base class `Object`'s `equals` function but unfortunately messed up the signature. This is because the author ended up overriding the `equals` function not overriding it. To override it the function needs to take an `Object` not a `Bigram`. 

This is where the `@Override` annotation can come in use. If the author of the code would have put this annotation on the method at compile time the compiler would have thrown an error saying there wasn't a method to override.

During the initial compilation is where you do get most of the benefit of the `@Override` annotation; however, it still can be of use beyond that. Your IDE can also use this information to add information to your code and help you develop in a safe manner. Finally, it can be used as a matter of communication with future developers of what methods are being overriden and which ones are not. 

In summary, when we override a function we should always annotate it with the `@Override` annotation. This will give you better safety and documentation of the classes you write.
