Last summer, the Supreme Court finally applied some common sense to the Computer Fraud and Abuse Act (CFAA). The government has long read this law to apply to pretty much any computer access it (or federal court litigants) doesn’t like, jeopardizing the livelihood of security researchers, app developers, and anyone who might access a system in ways the owner did not expect.
Allowing the government’s interpretation of the CFAA to move forward wasn’t an option, as the Supreme Court explained:
If the “exceeds authorized access” clause criminalizes every violation of a computer-use policy, then millions of otherwise law-abiding citizens are criminals. Take the workplace. Employers commonly state that computers and electronic devices can be used only for business purposes. So on the Government’s reading of the statute, an employee who sends a personal e-mail or reads the news using her work computer has violated the CFAA.
Or consider the Internet. Many websites, services, and databases “which provide ‘information’ from ‘protected computer[s],’ §1030(a)(2)(C)’” authorize a user’s access only upon his agreement to follow specified terms of service. If the “exceeds authorized access” clause encompasses violations of circumstance-based access restrictions on employers’ computers, it is difficult to see why it would not also encompass violations of such restrictions on website providers’ computers. And indeed, numerous amici explain why the Government’s reading of subsection (a)(2) would do just that: criminalize everything from embellishing an online-dating profile to using a pseudonym on Facebook
A decision [PDF] handed down by a New York federal court follows the Van Buren ruling to dismiss a lawsuit brought against a third-party app that collects and shares TikTok data to provide app users with another way to interact with the popular video sharing app. (h/t Orin Kerr)
Triller may exceed users’ expectations about what will be collected or shared, but it makes it pretty obvious it’s in the collection/sharing business. To utilize Triller, users have to opt in to data sharing right up front, as the court points out:
“To post, comment, or like videos, or to watch certain content on the App, users must create a Triller account.” ¶¶ 8, 30. When creating an account, a user is presented with a screen, depicted below, that provides various ways to sign up for an account:

This first step makes it clear Triller will need access to other social media services. Users can go the email route, but that won’t stop the app’s interaction with TikTok data. Hyperlinks on the sign-up screen directs users to the terms of service and privacy policy — something few users will (understandably) actually read.
But all the processes are in place to inform users about their interactions with Triller and its access to other social media services’ data. The court spends three pages describing the contents of these policies the litigant apparently did not read.
This is not to say users should be victimized by deliberately obtuse and convoluted terms of service agreements. If anything, more service providers should be required to explain, in plain English, what data will be collected and how it will be shared. But that’s a consumer law issue, not a CFAA issue, which is supposed to be limited to malicious hacking efforts.
Being unaware of what an app intends to do with user data is not a cause for action under the CFAA, especially now that some guardrails have been applied by the nation’s top court.
Wilson alleges that Triller exceeded its authorized access by causing users “to download and install the App” to their mobile devices without informing users that the App contained code that went beyond what users expected the App to do,” by collecting and then disclosing the users’ information. However, as Triller argues, even assuming that Wilson is not bound by the Terms and thus did not authorize Triller to collect and disclose her information, it is not the case that Triller collects this information by accessing parts of her device that she expected or understood to be “off limits” to Triller. Van Buren, 141 S. Ct. at 1662. Rather, Wilson merely alleges that Triller collects and then shares information about the manner in which she and other users interact through the App with Triller’s own servers. Thus, at most, Wilson alleges that Triller misused the information it collected about her, which is insufficient to state a claim under the CFAA.
Wilson can appeal. But she cannot revive this lawsuit at this level. The federal court says the Van Buren ruling — along with other facts in this case — make it impossible to bring an actionable claim.
Accordingly, Wilson’s CFAA claim is dismissed with prejudice.
That terminates the CFAA claims. Other arguments were raised, but the court isn’t impressed by any of them. The Video Privacy Protection Act (VPPA) is exhumed from Blockbuster’s grave because TikTok content is, after all, recorded video. Violations of PII (personally identifiable information) dissemination restrictions are alleged. These are tied together and they both fail as well.
While the complaint alleges what sort of information could be included on a user’s profile and then ultimately disclosed to the third parties, it contains no allegation as to what information was actually included on Wilson’s profile nor how that information could be used by a third party to identify Wilson. Indeed, the complaint lacks any allegation that would allow the Court to infer a “firm and readily foreseeable” connection between the information disclosed and Wilson’s identify, thus failing to state a claim under the VPPA even assuming the broader approach set out in Yershov.
These claims survive dismissal. So does Wilson’s claim about unjust enrichment under New York state law — something predicated almost entirely on the size of the hyperlinks directing users to Triller’s privacy policy and terms of service. Those can be amended, but there’s nothing in the decision that suggests they’ll survive dismissal again.
Wilson also brings a claim under Illinois’ more restrictive state law concerning user data (the same one used to secure a settlement from Clearview over its web scraping tactics), but it’s unclear how this law applies to a Illinois resident utilizing a service that is a Delaware corporation being sued in a New York federal court. It appears the opt-in process will be the determining factor, and that’s definitely going to weigh against the plaintiff. Unlike Clearview, which scrapes the web without obtaining permission from anyone or any site, Triller requires access to other social media sites to even function.
It’s a good decision that makes use of recent Supreme Court precedent to deter bogus CFAA claims. While Wilson may have legit claims under federal and state consumer laws (although this doesn’t appear to be the case here…), the CFAA should be limited to prosecution and lawsuits directed against actual malicious hacking, rather than app developers who are voluntarily given access to user information by users. This doesn’t mean entities like Triller should be let off the hook for obscuring data demands and sharing info behind walls of legal text. But the CFAA is the wrong tool to use to protect consumers from abusive apps.

☑️ If you know PHP and wish to start using Laravel, this is for you.
☑️ If you know any PHP framework and wish to try Laravel, this is for you.
🙅 If you already know Laravel (well), this tutorial may not help that much.
The official Laravel documentation is one of the best technical documentation. But, it is not designed to get beginners started with the framework step-by-step. It doesn’t follow the natural way of learning a new thing.
In this tutorial, we will first discuss what needs to be done next, and then see what Laravel offers to achieve that. In some cases, we’ll discuss why something exists.
Important to note that for getting to the depth of a topic/feature, the Laravel documentation is the only resource you’ll need.
We’ll start from scratch and code a simple Laravel web app together to learn the building blocks of Laravel and boost your confidence.
As you may have read:
The only way to learn a new programming language is by writing programs in it.
— Dennis Ritchie (creator of the C programming language)
Same way, you will learn a new framework by doing a small test project today.
Keep in mind that we do not plan to use all the features of Laravel in a single project. We will cover all the important features though.
You should be ready to get in the active mode from this point onwards. No more passive reading. I want you to code along, break things, witness magic, and call yourself a Laravel developer by the end of this journey.
Come on a ride with me. It’ll be fun, I promise!

The things that you need to make a Laravel web app run:
Depending on your OS, there are a few options available:
Mac
I recommend Valet. It is lightweight and the go-to choice of many devs.
Laravel Sail is a great choice too for Docker fans.
Linux
Laravel Sail is easier for new Linux users.
If you are comfortable with Linux, like me, go with the direct installations.
Windows
I recommend Laragon. It is not from the official Laravel team but works well.
Other good choices are Laravel Sail if you are comfortable with Docker. or Homestead if you have a powerful computer that can run a virtual environment.
If you haven’t come across Composer before, it’s the dependency manager for PHP. Our project depends on the Laravel framework. And the framework has a lot of other dependencies.
Using the Composer allows us to easily install and update all these direct dependencies and nested dependencies. That results in code reusability which is the reason frameworks can offer such a huge number of features.
Once your computer is prepared to run a Laravel web app, fire your first command to create the project.
composer create-project laravel/laravel my-blog
This command does three things:
my-blogcomposer install command to install the dependenciesAs you may have guessed from the project name, we are developing a simple blog as our sample Laravel web app today.
A core PHP (non-framework) project starts from an empty directory, but a Laravel project starts with the skeleton app to get you up and running.
Many developers use Laravel’s local development server to view the web app during development. For that open terminal, cd into the project directory, and fire:
php artisan serve
You will be presented with a URL. Open that and you’ll see Laravel’s default page.

Yay. It’s running. Great start.
I recommend using nginx to manage your local sites. You need to use it for production anyway.
Relax
There are many files and directories in the default Laravel web app structure. Please do not get overwhelmed. They are there for a reason and you do not need to know all of them to get started. We will cover them soon.
You may use your favorite GUI tool or log in to the database server via console and create a database. We will need the DB name and user credentials soon.
While a Laravel web app can run even without a DB, why would you use Laravel then?
It’s like going to McDonald’s and ordering only a Coke. Okay, some people do it. 😵💫
The configuration values of a Laravel project can be managed from various files inside the config directory. Things like database credentials, logging setup, email sending credentials, third-party API credentials, etc.
The config values of your local environment will be different from the ones on the production server. And if multiple team members are working on the project, they may also need to set different config values on their local computers. But, the files are common for all.
Hmmm… How could that be managed then?
Laravel uses PHP dotenv to let you configure project config values specific to your environment. The .env file is used for the same. It is not committed to the version control system (git) and everyone has their local copy of it.
The Laravel skeleton app creates the
.envfile automatically when you run thecomposer create-projectcommand. But when you clone an existing project, you need to duplicate it from the.env.examplefile yourself.
While there are many config values you can set in the .env file, we will discuss a few important ones only:
APP_NAME: A sane default. You may wish to change to ‘My Awesome Blog’APP_ENV: Nothing to change. Set this to ‘production’ on the live site.APP_KEY: Used for encryption. Automatically set by the composer create-project command. If you clone an existing project, run the php artisan key:generate command to set it.DB_*: Set respective config values here.Setting these should get you started. You may update others in the future.
Laravel instructs that the public directory must be the entry point for all the HTTP requests to your project. That is for security reasons. Your .env file must not be accessible from the outside.
Please do not try any hack around setting the project root to the public directory. If your host doesn’t allow it, change your host.

You already know a bunch of fundamental Laravel concepts now. Doing well!
Let us start with the articles table. The schema can be:
| id | integer |
| title | varchar |
| content | text |
| is_published | boolean (default: false) |
| created_at | datetime |
| updated_at | datetime |
Challenges
In a non-framework project, we create and manage the tables manually. A few of the issues that we face are:
With Laravel and other backend frameworks, Migrations solve these issues. Did you ask how? Read on.
Migrations are nothing but PHP files that define the schema using pre-defined syntax. The Laravel framework provides a command to ‘migrate’ the database i.e. apply the latest schema changes.
Let us not stress over the theory much. It will make sense once you practically make one. Please open the terminal (you should be inside the project directory) and fire the following command.
php artisan make:migration create_articles_table
The framework should have created a brand new file inside the database/migrations directory with some default content. The name of the file would be in the format of DATE_TIME_create_articles_table.php.
Please open the file in your favorite text editor/IDE (mine is VS Code). And make changes in the up() method to make it look like the following:
Schema::create('articles', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->text('content');
$table->boolean('is_published')->default(false);
$table->timestamps();
});
The code should speak for itself. That is the beauty of Laravel.
Ready to witness magic?
Run the following command to migrate the database:
php artisan migrate
The articles table will appear in your database now. Yeah, you saw it right. And the same command can be run on production and by the team members to create the table. They do not need to ask you for the table name or column details. We have all been there.
Tables can be created, updated, and removed with artisan commands in Laravel. You’ll never need to manually manage the tables in your database.
Fun fact: You can run the
php artisan migratecommand any number of times without affecting your DB.
Note: You’d find that many other tables were also generated. That is because Laravel comes with a few migration files out of the box. We won’t get into the details but you can update/remove them as needed in your actual projects.
I am excited to share one of the most loved Laravel weapons with you: Eloquent

If you’re new to the term ‘ORM’, it’s a technique where each database table is represented as a PHP class, and each table record is represented as an object of that class.
If you haven’t experienced the power of objects before, fasten your seatbelt. It’ll be an incredible ride with Eloquent.
Please fire the following command now:
php artisan make:model Article
A new file called Article.php should have been created inside the app/Models directory. It’s a blank class with one trait which we can skip for the time being.
Tip: You can create the model and migration files by firing a single command:
php artisan make:model Article --migration
All the database interaction is generally done using Eloquent models in Laravel web apps. There is no need to play directly with the database tables in most cases.
Laravel, like many other frameworks, follows some conventions. You may not find the complete list of conventions but following the code examples as per the official documentation goes a long way.
Our model name is Article. And Eloquent will assume the table name to be the plural (and snake cased) version of it i.e. articles. We can still specify the table name if the convention can’t be followed in some exceptional cases.
Similar conventions are followed for the primary key (id) and the timestamps (created_at and updated_at) as most of the tables need them. You need to specify them inside the Eloquent model only if they are different from the default values. Again, no need to write that boilerplate code in most cases. 🤗
All clear till now? Good.. Next plan is to add articles and then list them.
The endpoints (or URLs) in a core PHP project are decided by files. If the user opens ‘domain.com/about.php’ in the browser, the about.php file gets executed.
But for Laravel web apps, the HTTP server (nginx/apache) is instructed to serve all requests to public/index.php. That file boots the framework and looks at the routes to check whether there is a respective endpoint defined for the requested URL.
There are numerous benefits to this route pattern compared to the traditional way. One of the main benefits is control. Just like they keep only one main entrance gate for buildings for better security, the route pattern allows us to control the HTTP traffic at any moment in time.
Your first route
We have the articles table but no articles yet. Let’s add some. Please open the routes/web.php file in the text editor and add:
use App\Http\Controllers\ArticleController;
Route::get('/articles/create', [ArticleController::class, 'create']);
You just defined a new route where the endpoint is /articles/create. When the user opens that URL in the browser, the create() method of the ArticleController will be used to handle the request.
I have already assumed that you know a bit about the MVC architecture so let’s jump straight into the code.
You can either create a controller class in the app/Http/Controllers directory manually or use this command:
php artisan make:controller ArticleController
The controller code is a one-liner for this endpoint. All we need to do is display the add article page to the user.
<?php
namespace App\Http\Controllers;
class ArticleController extends Controller
{
public function create()
{
return view('articles.create');
}
}
Simple enough, we let the view file deliver the page.
The view files of Laravel are powered by the Blade templating engine. The extension of the view files is .blade.php and you can write HTML, PHP, and blade-syntax code to them.
Getting into the details of Blade is out of the scope of this article. For now, we will write simple HTML to keep things moving. As mentioned, we will also stay away from the designing part.
Please create a new file named created.blade.php in the resources/views/articles directory and add the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Add Article</title>
</head>
<body>
<form action="/articles" method="POST">
@csrf
<input type="text" name="title" placeholder="Title">
<textarea name="content" placeholder="Content"></textarea>
<input type="checkbox" name="is_published" value="1"> Publish?
<input type="submit" value="Add">
</form>
</body>
</html>
If the CSRF thing is new for you, the CSRF protection page inside the Laravel documentation does a great job explaining it.
The respective POST route
Route::post('/articles', [ArticleController::class, 'store']);
This route will handle the HTML form submission.
We are following the resource controller convention here. It is not compulsory but most people do follow it.
Congrats! You’re more than halfway there and believe me, it’s easier from here.
You’ll fall in love with the Validation features of Laravel. It is so easy to validate input data that you would want to do it.
Let’s see how:
use Illuminate\Http\Request;
public function store(Request $request)
{
$validated = $request->validate([
'title' => ['required', 'string', 'max:255', 'unique:articles'],
'content' => ['required', 'string'],
'is_published' => ['sometimes', 'boolean'],
]);
}
We are adding the store() method to the controller and validating the following rules with just four lines of code:
It still blows my mind 🤯 how can it be so easy to validate the inputs of a request.
Laravel offers an optional Form Request feature to move the validation (and authorization) code out of the controller to a separate class.
The surprise is not over yet. If the validation fails, Laravel redirects the user back to the previous page and sets the validation errors in the session automatically. You can loop through them and display them on the page as per your design.
Generally, the code to display the validation errors is put in the layout files for reusability. But for now, you can put it in the create.blade.php file.
<body>
@if ($errors->any())
<ul>
@foreach ($errors->all() as $error)
<li></li>
@endforeach
</ul>
@endif
// ...
This piece of code uses Blade directives @if and @foreach to display the validation errors in a list.
If you were to do the same code without Blade directives, it would look like:
<body>
<?php if ($errors->any()) { ?>
<ul>
<?php foreach ($errors->all() as $error) { ?>
<li><?php echo $error; ?></li>
<?php } ?>
</ul>
<?php } ?>
// ...
Feel the difference? You get it!
Open the controller again and append the following code to the store() method.
use App\Models\Article;
public function store(Request $request)
{
Article::create($validated);
}
That’s it! Did you expect the article saving code to be 10 lines long? 😃
This single line will add the new article with the submitted form details in the table. impressive! I know how you feel.
I invite you to go ahead and submit that form now.
Do not worry if you face an error like the following. Ours is a developer’s life.

The create() method of the Eloquent model accepts an array where keys are the column names and values are, well, the values.
In our example, we are passing the array of validated inputs to the create() method. But many developers use all of the inputs from the POST request which results in a security vulnerability ⚠️. Users can submit the form with some extra columns which are not supposed to be controlled by them (like id, timestamps, etc.)
Laravel Eloquent enables mass assignment protection out-of-the-box to prevent that. It cares for you.
And you need to specifically inform Eloquent about how you wanna deal with mass assignments. Please open the model file and append the following line:
protected $fillable = ['title', 'content', 'is_published'];
Cross your fingers again, open the browser, and submit that form. With luck, the article should successfully be stored in the database table now. Bingo!
You would want to give feedback to the user with a notification after the successful creation of a new article.
Laravel makes it a cinch. Open the store() method of the controller again:
return back()->with('message', 'Article added successfully.');
This is what makes developers fall in love with Laravel. It feels like you’re reading plain English.
The user gets redirected back and a flash session variable is set. A flash session variable is available for one request only and that is what we want.
Again, the handling of notifications is generally done in the layout files using some Javascript plugins. For now, you may put the following code in the create.blade.php for the demo.
<body>
@if (session('message'))
<div>
</div>
@endif
// ...
Add one more article using the form and you would be greeted with a success message this time.
I assume you would have added some articles while testing the add article functionality. Let’s list them on the page now. First, please add a new route:
Route::get('/articles', [ArticleController::class, 'index']);
You read it right. We are using the same URL but the HTTP method is different. When the user opens the ‘/articles’ page in the browser (a GET request), the controller’s index() method will be called. But the store() method is used when the form is submitted to add a new article (a POST request).
The controller code
Here’s how you fetch records from the database and pass them to the view file.
public function index()
{
$articles = Article::all();
return view('articles.index', compact('articles'));
}
I am sure you are not surprised this time. You already know the power of Laravel Eloquent now.
The
$articlesvariable is an instance of Collection (not an array) and we will briefly cover that soon.
Please create another file named index.blade.php in the resources/views/articles directory. I will cover just the body tag:
<body>
<table border="1">
<thead>
<tr>
<th>Title</th>
<th>Content</th>
<th>Published</th>
</tr>
</thead>
<tbody>
@foreach ($articles as $article)
<tr>
<td></td>
<td></td>
<td></td>
</tr>
@endforeach
</tbody>
</table>
</body>
The code is straight forward and you may now view the articles you have added on the /articles page now.
The limit string helper is provided by Laravel.
Tip: It is better to display paginated records (articles) when there are hundreds of them. Laravel has got your back for that too.
Pat your back. You did a great job. You can call yourself a Laravel developer now.
Okay, everything comes to an end. So is this tutorial.
Implementing the authentication feature to this project is one of the things I wished to include in this article but it is already too long.
And before discussing authentication, we have to learn about password hashing, middleware, and sessions in Laravel.
Another topic I wanted to touch on is Eloquent relationships. This feature is so powerful you’d never want to go back to the old days.
Goes without saying that tests are a must for your production-level projects. And Laravel supports you with testing too.
In short, we have barely scratched the surface here. Drop a comment if you want me to write on the subject more. We can continue this example project and make a series of articles.
Meanwhile, let me share some other Laravel goodies you may wanna explore.
Extras
Collections: Arrays with superpowers. Offers various methods to transform your arrays into almost any format.
Mails: I have never sent an email to a real person from the development site thanks to Laravel. Which I had done multiple times before it.
Queues: Delegating tasks to the background processes gives a huge performance boost. Laravel Horizon + Redis combo provides scalability with simplicity.
Logging: Enabled by default. All the app errors are logged inside the storage/logs directory. Helps with debugging a lot.
File Storage: Managing user-uploaded files doesn’t have to be complex. This feature is built on top of the stable and mature Flysystem PHP package.
Factories and Seeders: Quick generation of dummy data of your tables for demo and tests.
Artisan commands: You’ve already used some. There are many more in the basket. And you can create custom ones too. Quite helpful when combined with the scheduler.
Task scheduling: I bet you’d agree that setting up cronjobs the right way is hard. Not in Laravel. You’ve to see it to believe it.
And many more…
There are a thousand and seventy more things we can do for this project. If you are interested, here are a few options:

You have created a small project in Laravel and learned the basics. Time to celebrate. 🥳
I hope you enjoyed the journey as much as I did. Feel free to ask any questions below.

Before we learn about the money, let’s get this question out of the way:

A database engineer is responsible for providing the data infrastructure of a company or organization. This involves designing, creating, installing, configuring, debugging, optimizing, securing, and managing databases. Database engineers can either work as employees or as freelancers remotely or onsite.

As already indicated, a database engineer is responsible for providing the data infrastructure of a company or organization.
In particular, a database engineer has many responsibilities, such as the following 15 most popular activities performed by a database engineer today:
These are only some of the most common activities frequently handled by database engineers.

A database engineer is responsible for providing the data infrastructure of a company or organization. This involves designing, creating, installing, configuring, debugging, optimizing, securing, and managing databases. Database engineers can either work as employees or as freelancers remotely or onsite.
A data engineer prepares data to be used in data analytics and operations, essentially providing automated or semi-automated ways for data collection and creating pipelines that connect various data sources to database management systems such as the ones managed by a database engineer.
A data engineer focuses on filling data into a database system whereas a database engineer is focused on providing the database system in the first place. There are intersection points between data engineers and database engineers at the interface between data sources and data management.

Database administrators perform a similar role to database engineers in that they are responsible for setting up, installing, configuring, securing, and managing a database management system.
The focus is more on the technical maintenance of existing systems than the theoretical development of new solutions.
But the lines between those two job descriptions are blurry and often overlap significantly.
How much does a Database Engineer make per year?
Question: How much does a Database Engineer in the US make per year?

The average annual income of a Database Engineer in the United States is between $72,536 and $135,000, with an average of $103,652 and a statistical median of $106,589 per year.
This data is based on our meta-study of ten (10) salary aggregators sources such as Glassdoor, ZipRecruiter, and PayScale.

Okay, but what do you need to do to get there? What are the skill requirements and qualifications to make you become a professional developer in the area you desire?
Let’s find out next!
StackOverflow performs an annual survey asking professionals, coders, developers, researchers, and engineers various questions about their background and job satisfaction on their website.
Interestingly, when aggregating the data of the developers’ educational background, a good three quarters have an academic background.
Here’s the question asked by StackOverflow (source):
Which of the following best describes the highest level of formal education that you’ve completed?

However, if you don’t have a formal degree, don’t fear! Many of the respondents with degrees don’t have a degree in their field—so it may not be of much value for their coding careers anyways.
Also, about one out of four don’t have a formal degree and still succeeds in their field! You certainly don’t need a degree if you’re committed to your own success!
The percentage of freelance developers increases steadily. The fraction of freelance developers has already reached 11.21%!
This indicates that more and more work will be done in a more flexible work environment—and fewer and fewer companies and clients want to hire inflexible talent.
Here are the stats from the StackOverflow developer survey (source):

These are the languages you want to focus on when starting out as a coder:

And don’t worry—if you feel stuck or struggle with a nasty bug. We all go through it. Here’s what SO survey respondents and professional developers do when they’re stuck:

Enough theory. Let’s get some practice!
Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation.
To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?
You build high-value coding skills by working on practical coding projects!
Do you want to stop learning with toy projects and focus on practical code projects that earn you money and solve real problems for people?

When it comes to badassery, Chuck Norris is on many top 10 lists. SergiuHellDragoon put Chuck’s skills to the test using Ultimate Epic Battle Simulator 2 and an army of 2400 Chucks versus a million Spartan Warriors. Despite the seemingly impossible odds, the overpowered Chucks made quick work of the soldiers.

Unlike Miguel, I am going to take the Buffalo shooter’s manifesto at face value until proven otherwise.
I read it and can tell you that several posts will come from an analysis of it.
But I want to hammer home on this point again:
The shooter states that he targeted locations where CCW was prohibited or low.
He chose a location where if people were armed they would be limited to 10 round magazines and not have access to rifles.
He stated he would be wearing level IIIA armor that could defeat the ammunition carried by the guards at Tops Market.
He thought this attack out to minimize danger to himself, and considering that he was taken alive, it worked.
You need to be prepared to fight someone who is wearing armor and knows you will only have a handgun.
You need to start training to put the first few into the pelvic girdle just in case your assailant is wearing armor.

Back in April, Google delayed when G Suite legacy free-edition users had to start paying for Workspace. The company will now let you stay on a "Free Legacy Edition of G Suite for personal use" as the "no-cost" alternative in a rather notable policy change. 9to5Google reports: This "no-cost" option is for people that aren’t interested in paying for Workspace but want to retain access to their data and not just export via Google Takeout. For the past few months, people have been waiting to join a waitlist for this alternative. In a change of plans, there’s no longer a waiting list, and these old users can sign-up for no-cost Legacy G Suite now. Head to your account’s Google Admin Console as there are many reports of it going live this afternoon. You have until June 27 to pick a transition path.
Most notably, you can "continue using your custom domain with Gmail." […] Besides the custom Gmail domain, you will "retain access to no-cost Google services" and "keep your purchases and data." […] However, you must confirm to Google that your usage is for non-commercial personal use: "Google may remove business functionality from this offering and transition businesses to Google Workspace. Additionally, this option will not include support."

Despite its acceleration abilities, the Tesla Model S is a relativelt tame-looking car from the outside. But that all changed after The Real Life Guys got their hands on one. The German YouTubers took a Model S and converted it into a Model T by lifting it more than two feet and equipping it with tank tracks. Turn on subtitles.
