"An EV motor has been developed that uses no magnets, thus lessening the United States’ reliance on Chinese magnets (which make up 97% of the world’s supply)," writes Slashdot reader nickwinlund77, adding: "I wonder what the motor’s performance is like on high grade roads?" New Atlas reports: German company Mahle has just announced a new electric motor that sounds like it solves a lot of problems in a very tidy manner. The new Mahle design uses no magnets, instead using powered coils in its rotor. Unlike previous efforts, it transfers power to the spinning rotor using contactless induction — so there are basically no wear surfaces. This should make it extremely durable — not that electric motors have a reputation for needing much maintenance. The lack of expensive metals should make it cheaper to manufacture than typical permanent-magnet motors. Mahle says the ability to tune and change the parameters of the rotor’s magnetism instead of being stuck with what a permanent magnet offers has allowed its engineers to achieve efficiencies above 95 percent right through the range of operating speeds — "a level that has only been achieved by Formula E racing cars." It’s also particularly efficient at high speeds, so it could help squeeze a few extra miles out of a battery in normal use. The company says it’ll scale nicely from sizes relevant to compact cars up to commercial vehicles.
"Our magnet-free motor can certainly be described as a breakthrough, because it provides several advantages that have not yet been combined in a product of this type," says Dr. Martin Berger, Mahle’s VP of Corporate Research and Advanced Engineering. "As a result, we can offer our customers a product with outstanding efficiency at a comparatively low cost." Mass production is about two and a half years away, according to IEEE Spectrum, and Mahle has not yet nominated which auto manufacturers it’s dealing with, but test samples are already starting to circulate.
Problem Formulation: How to insert at the first position of a list in Python?
Solution:
Use the list.insert(0, x) element to insert the element x at the first position 0 in the list. All elements j>0 will be moved by one index position to the right.
You create the list [5, 1, 3, 8, 7, 9, 2] and store it in the variable lst. Now, you insert the new element 42 to the first position in the list with index 0. Note that Python uses zero-based indexing so the first position has index 0. The resulting list has 8 elements instead of only 7. The new element 42 is at the head of the list. All remaining elements are shifted by one position to the right.
To dive deeper into the very important list.insert() method, I’d recommend you watch my full explainer video here:
Note that some people recommend to insert an element at the first position of a list like so:
While the output looks the same, this doesn’t actually solve the problem because the list concatenation operator list_1 + list_2 creates a new list with the elements of two existing lists. The original lists remain unchanged. Only by assigning it to the variable lst, you overwrite it. However, if another variable would point to the old list, this option based on list concatenation wouldn’t work because the old list remains unchanged.
In this example, you create two lists lst_1 and lst_2 both referring to the same list object in memory. You try to insert the new element at the beginning of the list using the problematic method. And you obtain a clash—both lists refer to different objects in memory!
>>> lst_2
['new', 1, 2, 3]
>>> lst_1
[1, 2, 3]
Thus, the list.insert(0, 'new') method is superior to list concatenation to insert an element at a given position in the list.
In this example, I will learn you how to use fullcalendar with livewire example. We will explain step-by-step laravel livewire fullcalendar integration. you can easily make livewire fullcalendar integration in laravel. we will describe laravel livewire fullcalendar integration.
Here, I will give you full example for simply livewire fullcalendar integration in laravel native as bellow.
Step 1 : Install Laravel App
In First step, We need to get fresh laravel version application using bellow command. So Let’s open terminal and run bellow command.
composer create-project --prefer-dist laravel/laravel blog
Step 2 : Setup Database Configuration
After successfully install laravel app thenafter configure databse setup. We will open “.env” file and change the database name, username and password in the env file.
In this step, You will simply install livewire to our laravel application using bellow command:
composer require livewire/livewire
Step 4 : Create items Table and Model
In this step we have to create migration for items table using Laravel php artisan command, so first fire bellow command:
php artisan make:model Event -m
After this command you have to put bellow code in your migration file for create items table.
following path: /database/migrations/2021_04_10_102325_create_events_table.php
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateEventsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('events', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->string('start');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('events');
}
}
Now we require to run migration be bellow command:
php artisan migrate
After you have to put bellow code in your model file for create items table.
following path:/app/Models/Event.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Event extends Model
{
use HasFactory;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'title',
'start',
];
}
Step:5 Create Route
In thi step,now, we need to add resource route for livewire fullcalendar integration in application. so open your “routes/web.php” file and add following route.
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Livewire\Calendar;
use App\Models\Event;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::view('/', 'home');
Livewire::component('calendar', Calendar::class);
Step 6 : Create Component
Now, You can create livewire component using bellow command, So Let’s run bellow command to create calendar form component:
It’s easy to exercise the muscles you can see—your biceps, your quads—but there are more muscles in your body than just the big ones. We’ve talked before about the muscles in your hands and forearms, which help to give you a strong grip, and today I’d like to bring your attention to your feet.
Your feet contain more little muscles than you probably realize, including four separate layers of them on the bottom of your feet. These “intrinsic” muscles help support your arch, move your toes, and more.
If you engage in a variety of exercises, the muscles of your feet and lower legs will probably get plenty of work. But it doesn’t hurt to take a few minutes to give them some special attention—and if you’re a runner, or if you need extra support for your feet in exercises like yoga, you might find that some foot exercises help you with your other activities.
Try some foot yoga
Yoga can provide a mindful focus on the way our body works, strengthening and stretching muscles in ways we don’t normally think about. Fortunately, Adriene (of Yoga With Adriene) has a yoga flow for the feet, so you can follow along and get to know all those little foot muscles.
G/O Media may get a commission
Do a strength routine for your feet
If yoga isn’t your style, you can do foot exercises in sets and reps. This video from PodiumRunner will show you a few. One that might blow your mind if you never thought about your arch as a muscle: stand with your feet flat on the ground, then pull your arch upwards, making your footprint shorter and your instep taller. You have a muscle that does this! You can contract it on purpose! Amazing.
Scrunch a towel
One exercise not mentioned above is the towel scrunch. Set a dish towel on the ground, place your toes on it, then (sitting or standing) scrunch your toes to bunch the towel up. Repeat until the whole towel is in a heap under your feet.
This is a fun one because you can actually load it. Put a small weight, like a water bottle, on the opposite end of a towel, to make it harder to pull toward you.
Run on uneven ground
The real function of our feet is to support us as we do other things in life, so don’t think you’re limited to just doing focused foot exercises on their own. Going out for a trail run, or even jogging on sand or grass, will constantly challenge your feet to support you at a variety of angles and positions. If you have a place you can safely run barefoot, give that a try as well.
Elon Musk, the CEO of Tesla, SpaceX, and other startups, provided an explanation for his bizarre tweets that have gotten him into trouble with regulators, customers and competitors.
Look, I know I sometimes say or post strange things, but that’s just how my brain works. To anyone I’ve offended, I just want to say I reinvented electric cars, and I’m sending people to Mars in a rocket ship. Did you think I was also going to be a chill, normal dude?
Musk probably isn’t lying by blaming his bizarre or downright insulting tweets on his eccentricity. After all, we’re talking about the same guy who changed his job title to the "Technoking of Tesla" in a US Securities and Exchange Commission filing.
Now, one would be right to argue that PayPal’s former co-founder should know better than that. Indeed, there are plenty of examples of Musk’s aggressive and offensive tweeting.
The Most Bizarre Musk Tweets
In April 2020 during the height of the coronavirus pandemic when the US was reporting more than 20,000 new daily cases, the Tesla chief demanded that the government reopen the economy and "FREE AMERICA NOW."
Musk also caused quite a turmoil with a thinly-veiled threat in another tweet in which he announced that workers who unionized would lose their company-paid stock options. The National Labor Relations Board was unsympathetic, ordering Musk to delete that one.
Offending British cave explorer Vernon Unsworth by calling him a "pedo guy" in front of his millions of Twitter followers definitely isn’t one of Musk’s finer moments either.
"Funding Secured"
But the most famous Musk tweet has got to be a 2018 post in which he announced taking Tesla private at $420/share. Shares of Tesla tumbled following the "funding secured."
Am considering taking Tesla private at $420. Funding secured.
It was this tweet in particular that prompted the US Securities and Exchange Commission to sue Musk in federal court, charging the technology entrepreneur with committing securities fraud by manipulating stock prices with tweets. All in all, the "funding secured" tweet cost Musk a $20 million fine and a position as Tesla’s chairman of the board.
While it’s no secret that mobile apps have ability to help us in different areas of our lives, you may be surprised to learn that there are a growing number of apps specifically designed to assist people with dementia. These vary from memory games to help slow down the progression of dementia, to reminder apps that can help dementia patients remain more independent.
In addition, there are apps aimed at supporting family members and caregivers too. Let’s take a look at some of the best apps for those with dementia, as well as their loved ones.

I’m actually making history tonight as the first person with Asperger’s to host SNL. Or, at least the first to admit it.
Actually, this "misleading claim" is currently being fact-checked by Twitter. Dan Aykroyd "was the first person with Asperger’s syndrome to host the show." Though they may have him confused with being an asssburger. Just saying, Dan Aykroyd is both the least talented Blues Brother, Ghostbuster and groundskeeper at the Bushwood Country Club.
To anyone I’ve offended [on Twitter], I just want to say, I reinvented electric cars, and I’m sending people to Mars on a rocket ship. Did you think I was also going to be a chill, normal dude?
All I hear all the time is, ‘Elon Musk, all he ever does is smoke weed on podcasts.’ Like I go from podcast to podcast lighting up joints. It happened once. It’s like reducing O.J. Simpson to "Murderer." It happened one time. Fun fact. O.J. Also hosted this show in ’79. And again in ’96. Killed both times."
I ask for so little in life. Please, to the god or gods of content, have OJ Simpson respond to Musk on Twitter.
The controversy was much ado about nothing. Elon Musk was funny. A Chinese rocket didn’t crash anywhere in our country. SNL, once known for brilliant political satire, once again ignored the wealth of material provided them by Joe Biden this week. Overall, another bland Saturday at 30 Rock.
Have you ever come across text files with repeated lines and duplicate words? Maybe you regularly work with command output and want to filter those for distinct strings. When it comes to text files and the removal of redundant data in Linux, the uniq command is your best bet.
In this article, we will discuss the uniq command in-depth, along with a detailed guide on how to use the command to remove duplicate lines from a text file.
What Is the uniq Command?
The uniq command in Linux is used to display identical lines in a text file. This command can be helpful if you want to remove duplicate words or strings from a text file. Since the uniq command matches adjacent lines for finding redundant copies, it only works with sorted text files.
Luckily, you can pipe the sort command with uniq to organize the text file in a way that is compatible with the command. Apart from displaying repeated lines, the uniq command can also count the occurrence of duplicate lines in a text file.
How to Use the uniq Command
There are various options and flags that you can use with uniq. Some of them are basic and perform simple operations such as printing repeated lines, while others are for advanced users who frequently work with text files on Linux.
Basic Syntax
The basic syntax of the uniq command is:
uniq option input output
…where option is the flag used to invoke specific methods of the command, input is the text file for processing, and output is the path of the file that will store the output.
The output argument is optional and can be skipped. If a user doesn’t specify the input file, uniq takes data from the standard output as the input. This allows a user to pipe uniq with other Linux commands.
Example Text File
We’ll be using the text file duplicate.txt as the input for the command.
127.0.0.1 TCP 127.0.0.1 UDP Do catch this DO CATCH THIS Don't match this Don't catch this This is a text file. This is a text file. THIS IS A TEXT FILE. Unique lines are really rare.
Note that we have already sorted this text file using the sort command. If you are working with some other text file, you can sort it using the following command:
sort filename.txt > sorted.txt
Remove Duplicate Lines
The most basic use of uniq is to remove repeated strings from the input and print unique output.
uniq duplicate.txt
Output:
Notice that the system doesn’t display the second occurrence of the line This is a text file. Also, the aforementioned command only prints the unique lines in the file and doesn’t affect the content of the original text file.
Count Repeated Lines
To output the number of repeated lines in a text file, use the -c flag with the default command.
uniq -c duplicate.txt
Output:
The system displays the count of each line that exists in the text file. You can see that the line This is a text file occurs two times in the file. By default, the uniq command is case-sensitive.
Print Only Repeated Lines
To only print duplicate lines from the text file, use the -D flag. The -D stands for Duplicate.
uniq -D duplicate.txt
The system will display output as follows.
This is a text file. This is a text file.
Skip Fields While Checking for Duplicates
If you want to skip a certain number of fields while matching the strings, you can use the -f flag with the command. The -f stands for Field.
Consider the following text file fields.txt.
192.168.0.1 TCP 127.0.0.1 TCP 354.231.1.1 TCP Linux FS Windows FS macOS FS
To skip the first field:
uniq -f 1 fields.txt
Output:
192.168.0.1 TCP Linux FS
The aforementioned command skipped the first field (the IP addresses and OS names) and matched the second word (TCP and FS). Then, it displayed the first occurrence of each match as the output.
Ignore Characters When Comparing
Like skipping fields, you can skip characters as well. The -s flag allows you to specify the number of characters to skip while matching duplicate lines. This feature helps when the data you are working with is in the form of a list as follows:
1. First 2. Second 3. Second 4. Second 5. Third 6. Third 7. Fourth 8. Fifth
To ignore the first two characters (the list numberings) in the file list.txt:
uniq -s 2 list.txt
Output:
In the output above, the first two characters were ignored and the rest of them were matched for unique lines.
Check First N Number of Characters for Duplicates
The -w flag allows you to check only a fixed number of characters for duplicates. For example:
uniq -w 2 duplicate.txt
The aforementioned command will only match the first two characters and will print unique lines if any.
Output:
Remove Case Sensitivity
As mentioned above, uniq is case-sensitive while matching lines in a file. To ignore the character case, use the -i option with the command.
uniq -i duplicate.txt
You will see the following output.
Notice in the output above, uniq did not display the lines DO CATCH THIS and THIS IS A TEXT FILE.
Send Output to a File
To send the output of the uniq command to a file, you can use the Output Redirection (>) character as follows:
uniq -i duplicate.txt > otherfile.txt
While sending an output to a text file, the system doesn’t display the output of the command. You can check the content of the new file using the cat command.
Most of the time while managing Linux servers, you will be either working on the terminal or editing text files. Therefore, knowing how to remove redundant copies of lines in a text file can be a great asset to your Linux skill set.
Working with text files can be frustrating if you don’t know how to filter and sort text in a file. To make your work easier, Linux has several text editing commands such as sed and awk that allow you to work efficiently with text files and command-line outputs.
