Lock
Published: 2022-04-06 09:32:50

lock writes a class based on Java, mainly through hardware-dependent CPU instructions to achieve data synchronization

lock must be released manually

There are multiple ways to acquire locks. You can try to acquire locks, and threads do not have to wait all the time.

lock can determine the state of the lock

lcok is reentrant, decidable, and fair

lock a lot of synchronization, advanced settings can be made (polling, timing, interrupts, etc.)

How to reset an elements inherited properties using css?
Tags: css, html, webdev
Published: 2022-04-06 09:26:31

If an element is inheriting alot of css properties you can reset all properties to their unset state at once using `all: unset` property.

This can come handy if your element is inheriting alot of properties due to css frameworks, custom css or any third party css imports.

{% codepen https://codepen.io/hunzaboy/pen/BaJYGZr default-tab=html,result %}

According to MDN:
> The `all` shorthand CSS property resets all of an element's properties except unicode-bidi, direction, and CSS Custom Properties. It can set properties to their initial or inherited values, or to the values specified in another cascade layer or stylesheet origin.

You can read more about `all` property [here](https://developer.mozilla.org/en-US/docs/Web/CSS/all)

synchronized lock
Published: 2022-04-06 09:21:51

Data synchronization based on the underlying jvm, not suitable for stack traces

Synchronized is when the synchronous code block is executed or an exception occurs, the jvm will let the thread release the lock, which cannot be released manually

The synchronized species joins the A thread to obtain a lock or is in a blocked state, then other threads will keep waiting

synchronized cannot determine the state of the lock

Synchronized is reentrant, uninterruptible, unfair

Synchronized has a small amount of synchronization and cannot perform advanced functions (polling, timing, interruptible, etc.)

Synchronized can improve performance, because it is a built-in property of JVM with the possibility of further optimization

## Java
String，String Builder，String Buffer
Published: 2022-04-06 09:20:22

are all classes that manipulate strings

String Builder and StringBuffer inherit the Abstract String Builder abstract class and implement the Char Sequence interface

The object declared by String is immutable, and each operation will generate a new String object pointing to the new object

Both String Builder and StringBuffer can operate on the basis of the original object

It is not recommended to use String to declare when the content of the string is frequently changed

------------------------multithreading angle----------------------

String Buffer thread safety (the synchronized keyword is added to the related methods)

String Builder is not thread-safe and has higher performance than String Buffer

String Builder is recommended for single-threaded environments, and String Buffer is recommended for multi-threaded environments

## java
Integer and int
Published: 2022-04-06 09:16:45

int is a basic data type, Integer is a reference data type, a wrapper class for int

The default value of int is 0, and the default value of Integer is None

int is not completely object-oriented processing, Integer is mostly object-oriented processing

Integer is a Java object. After instantiation, there will be an object header in the JVM and its Class object will be loaded

Int is compared with ==, and Integer is compared with equals (-128 to 128 can be compared with ==, obtained from the constant pool)

It is recommended to use int for temporary objects, which will be directly allocated in the stack memory; it is recommended to use Integer to define entity classes

How do you lead a team of developers?
Tags: discuss, career, webdev
Published: 2022-04-06 09:12:39


### Let me start off...
...by saying that im in a kind of "weird" situation right now i would say, thats why im writing this. 

I've been working at a company as a full stack web developer for almost 3 years now.
My company consists of different departments. We have our database engineers, thats one department, then we've got our Wordpress-dudes in another department and lastly the Webdev Department which im part of. We've got like 7-8 employees working in the database-engineer department, then we've got 7 employees working in the webdev department, including me and lastly 3 employees in the wordpress department.

### Now to my situation
I'm supposed to be the "teamleader" now for the webdev AND the wordpress department. Don't get me wrong, i know my way around Wordpress even tho i don't like it that much from a developers point of view (sorry dear wordpress developers) and i also did some theme and plugin development over my last few years, so wordpress is not the issue itself. 

### My "issues" are coming from another end:
- First of all, it's my first time being a teamleader for anything businessrelated.
- Second of all, my company is in sort of a weird transition right now, when it comes down to projectmanagement. Since i've joined the company they have been managing their projects in a waterfall-model type which i really dont like. Not only because its an sort of outdated way of projectmanagement, also because we have alot of projects where the estimated effort turns out to be way more at the end, ending in the customer being sort of angry and the team being pissed because they have to implement yet another feature which wasnt in the planning right from the beginning but is wished by the customer or hasn't been seen from the beginning. Everything is sort of transitioning more into an a pseudo-agile direction now with people wanting kanban boards, daily scrum meetings, sprints and so on. I also know my way around Scrum and developing agile, i also visited a scrum schooling and have a certificate for that so thats also not the problem. I also know all the issues about companies not being able to transition from waterfall to agile development because of several reasons and all that.

I don't want to completely fail as a teamleader, also i dont really know what to do first. I want the team to transition to a more scrum-like or agile-like development style simply because i see alot of improvements there on one side, but on the other side i dont see us actually being able to do that because of our financial/commercial management being someone who only wants to hear numbers and doesnt care about the rest. i also see some other parts of the upper management not having the mindset for us actually being an agile team and end up like this:

How would you approach this situation? Do you mighty-teamleaders have some things you could give me on my way through this journey? What would you do or not do in my situation? Any question?

Why am I finding C so difficult?
Tags: c, programming, discuss, college
Published: 2022-04-06 08:46:15

Hi folks,

Heading into the final few weeks of my last semester of year 2 at university and it's _okay_.

The one thing that is breaking my brain more than other modules, is the C module. Not sure why I'm finding it so difficult but it's mind boggling! I get the idea of pointers, structs, memory allocation, etc. but I just can't bring it all together to develop a clear or even a basic understanding of the language.

I think it's because I was spoiled - the last 2 years we've been doing Java, JS and Python mostly so it's been very high level and I didn't need to worry about things like the above. We're doing linked lists now and while I get the concept of a linked list, implementing them in C is a different ballgame entirely. 

Has anyone else had a similar experience? If so, any tips to make C more palatable?

Thanks gang!
Laravel 8 Eloquent Query first() and firstOrFail() Example
Tags: laravel, php, javascript, tutorial
Published: 2022-04-06 08:45:15

Originally posted @ https://codeanddeploy.com visit and download the sample code: https://codeanddeploy.com/blog/laravel/laravel-8-eloquent-query-first-and-firstorfail-example

In this Laravel example, I'm sharing the **first() and firstOrFail() methods on the Laravel Eloquent query**. The **Laravel Eloquent first()** method will help us to return the first record found from the database while the **Laravel Eloquent firstOrFail()** will abort if no record is found in your query.

 

So if you need to abort the process if no record is found you need the firstOrFail() method on Laravel Eloquent.

 

Below is an example of each.

 

## Laravel Eloquent first() basic example

The below example will display null if no record is found.


```php
$post = Post::where('title', 'Post 1')->first();

dd($post);
```

But if you need to abort using `first()` method then this is the example code:

```php
$post = Post::where('title', 'Post 111')->first();

if(is_null($post)) {
    return abort(404);
}
dd($post);
 
```

As you can see we added checking if the returned is null. Then call abort() function.

## Laravel Eloquent firstOrFail() basic example

But using the code example below our code will be shortened if you need to abort the process if no record is found using `firstOrFail()` method in Laravel eloquent.

```php
$post = Post::where('title', 'Post 1')->firstOrFail();

dd($post);
```

I hope this tutorial can help you. Kindly visit here https://codeanddeploy.com/blog/laravel/laravel-8-eloquent-query-first-and-firstorfail-example if you want to download this code.
Laravel 8 Eloquent Query find() and findOrFail() Example
Published: 2022-04-06 08:37:29

Originally posted @ https://codeanddeploy.com visit and download the sample code: https://codeanddeploy.com/blog/laravel/laravel-8-eloquent-query-find-and-findorfail-example

In this post, I will share on how to use find() and findOrFail() methods in Laravel Eloquent query. And the different usage of both of these methods. Usually, we use find() method for finding by model primary key but sometimes we need to use abort() function helper if the primary key value is not found. That's why findOrFail() method in Laravel eloquent is useful for this kind of scenario.

 

## Laravel Eloquent find() basic example

The below example will just display null if no record is found by the given ID.

```php
$post = Post::find(1);

dd($post);
```

But if we need to abort the process if not record found using find() then see the following code below:

```php
$post = Post::find(1);

if(is_null($post)){
   return abort(404);
}

dd($post);
```

## Laravel Eloquent findOrFail() basic example

If you want to abort the process like the above code then the below code will do the same.

```php
$post = Post::findOrFail(1);

dd($post);
```

As you can see above example using **findOrFail()** method will shorten your code if you need to abort the process if no record is found. But still, depend on your scenario. I hope you find this helpful.

**_DEVxDeepgram Hackathon_ | DG Word Games**

— 


### Overview of My Submission

![Banner](https://raw.githubusercontent.com/sharmavikashkr/dg-word-games/master/public/banner.png)

#### What

This project uses [Deepgram](https://deepgram.com/)'s realtime STT transcription API to enable playing the three most popular word/number games in the world:

- Crosswords
- Wordle
- Sudoku

#### How

This app is built in react.

It pre-loads in the redux store:
- a random Crosswords puzzle from [this repo](https://github.com/doshea/nyt_crosswords/)
- a wordle word from [this list](src/store/constants/wordleWords.js).
- a random sudoku puzzle from [this api](https://github.com/bertoort/sugoku)

Then, root component transcripts the user's speech in realtime and passes the transcription results to each game components as prop. It requests for Deepgram realtime transcription key from another [API](https://github.com/sharmavikashkr/dgwordgames-api).

##### Crosswords
The crosswords puzzle can be played by speaking out your guesses.
Eg. **"twenty five across blend"**
- It identifies the direction (__across/down__).
- It uses a [words-to-numbers](https://www.npmjs.com/package/words-to-numbers) library to convert the number in words to integers.
- It then checks if the guess word's (in this case, "blend") length is equal to the answer's.
- It then set's the user guess against the relevant clue.

##### Wordle
The wordle puzzle can be played by speaking out just the guess.
Eg. **"blend"**
- It will check if the guess word's (in this case, "blend") length is equal to 5.
- It will add the guess to the guesslist.

##### Sudoku
The sudoku puzzle can be played by speaking out position with the guess.
Eg. **"five cross two seven"**
- It uses a [words-to-numbers](https://www.npmjs.com/package/words-to-numbers) library to convert the number in words to integers.
- It will find the position of the guess by finding row and column separated by "cross".
- It will put the guess in it's box position.

Laravel 8 Eloquent firstOr() Example
Tags: laravel, tips, php, javascript
Published: 2022-04-06 08:34:49

Originally posted @ https://codeanddeploy.com visit and download the sample code: https://codeanddeploy.com/blog/laravel/laravel-8-eloquent-firstor-example


In this post, I will explain what is the usage of **Laravel Eloquent firstOr()** and its importance. Laravel provides **firstOr()** that enables us to put another logic inside closure if the record is not found in our database.

 

**I will give you several examples:**

 

## Create Not Found Record

In this example, it will search a post title record if not found then it will create a post using provided attributes then display the instance. See the below example:

```php
$attributes = [
    'title' => 'Post 100',
    'description' => 'Description for post 100',
    'body' => 'Body for post 100'
];

$post = Post::where("title", $attributes['title'])->firstOr(function () use($attributes) {
    return Post::create($attributes);
});  
  
print_r($post); die;
```

## Display Default Not Found Record

In this example we will find the record if not found then we will display the default record.


```php
$post = Post::where('title', 'post title'])->firstOr(function () {
    return Post::where('title', 'default post')->first();
});  
  
print_r($post); die;
```
