Fred has not set the Premier League alight since joining Manchester United from Shakhtar

Donetsk, but he feels he is making strides.

New Manchester United signing Fred is starting to feel good about his adaptation at the club

after an admittedly slow start.

Fred is reported to have cost United £53million after impressing at Shakhtar Donetsk during

a five-year spell in Ukraine, apparently attracting interest from Manchester City during that

time.

Although he showed flashes of class, Fred's form in his first few matches was disappointing

and he looked rusty on his Premier League debut against Leicester City.

But the Brazil international is feeling better about his contributions, after scoring his

first goal for the club in the 1-1 draw with Wolves last Saturday.

Fred told MUTV: "I was really happy,"

"I even had the chance to dedicate it to my son that will be born soon.

This goal was really important to me and I hope it is the first of many.

"I'm still adapting to many things and in the previous games I wasn't playing as well

as I was playing before I joined the club.

"Now I feel much better and to be able to score my first goal was really amazing."

Instagram Is Ruining Your Life - Duration: 7:39.

A study conducted by the Royal Society for Public Health last year took a look

at the effects of using social media on the mental health of 1,500 individuals

they discovered that out of the five most commonly used social media

platforms frequent usage in four of them Twitter Facebook snapchat and Instagram

caused mental health issues while only one YouTube had a somewhat positive

effect on mental health the four platforms that cause mental health

issues with then ranked from least damaging to most damaging and here are

the results Twitter being the least followed by

Facebook followed by snapchat and at the very bottom the social media platform

that messes with your head the most Instagram now this brings up the

question of well why why is Instagram the platform that causes the most mental

health problems and why is it that using social media platforms is ruining your

life and that's what we're gonna talk about in today's video see the thing is

our brain is constantly collecting data about our environment without us really

noticing it it does this for a variety of reasons such as making sure that

we're not in danger or to see if there aren't any resources nearby but one of

the most important reasons it does this is to check and see where we currently

stand in what's called the social hierarchy see within every social

situation within every environment that you find yourself in whether it be at

school at work or even at a nightclub there is a hierarchy a pyramid the

people at the top of this pyramid are the ones who have the most power the

ones who are the strongest the wealthiest the ones with the most

influence now our brain determines where people stand on this pyramid by

primarily looking at visual cues we look at someone's physique how muscular and

fit they are to determine physical strength we look at things that someone

owns like clothing cars and their lifestyle to determine someone's wealth

and we look at the types of people they surround themselves with to determine

their level of influence we look at all of these things to determine where the

people around us are on the pyramid but we also use this information to

determine where we are on the exact same pyramid now back in a day before the

invention of the internet before everyone started using social media

there weren't that many people to compare ourselves to where your brain

would simply look at the people that you spent the most time around and

make an estimation off of that for example when you were still in school

your brain mainly focused on the kids that attended your school now let's say

for the purposes of this video that you were a perfectly average kid back in

high school you had an average amount of friends you came from an average family

with an average income you were average looking as average as can be when your

brain compared you to the people in your surrounding it would probably look

something like this there were probably only a couple of kids were above you on

the pyramid the popular kids captains of sports teams members of student council

etc but to be honest there really weren't that many maybe only five to ten

percent of the school population at the same time they were probably also a

couple of kids who are below you on the pyramid kids who didn't have any friends

who had a hard time socializing these kids probably made up about another five

to ten percent of the school population the remaining 80% of the school

population were people who were pretty much average just like you just really

average kids from average families with really normal lives you know some might

have been slightly above and some slightly below you but most people were

pretty close to each other on the pyramid now back in the day when you

were in an environment like this you didn't feel like you were inferior to

the people around you sure there were a couple people who are better than you at

things who are above you on the pyramid but the vast majority of people were

essentially your equals at least that's how your brain saw it but fast forward

to modern times even if you're a seventeen year old kid in high school

surrounded by mostly average kids who are just like you your brain thinks that

you are competing against extremely successful people it believes that there

are extremely wealthy fit and popular people who are around your age all

around you and it believes this because of the amount of time you spend on

social media see the average American now spends on average two hours every

single day on social media however that's including adults and the elderly

a recent study actually found that the average teenager is spending around six

to nine hours on social media every single day and the thing is when you're

spending that many hours on social media your brain no longer sees your current

environment as it is it starts to believe that all of these people you see

on Instagram are people who are actually around you in real life and then it

starts to look at their lives and it compares it to your own it notices that

these people are so much better look then you mainly because of things like

lighting angles filters and Photoshop then your brain starts to believe that

there are all these people who are much more successful than you wealthier than

you it sees people your age driving fancy cars going on exotic vacations

wearing expensive clothes and then your brain starts to believe that there are

all of these people living happier lives than you hundreds and hundreds of

pictures smiling as if every single second of their lives were filled with

bliss by spending this much time on social media you trick your brain into

believing that you are no longer average that you are no longer somewhere in the

middle of the pyramid it starts to believe that you are actually in the

bottom 5% instead of having just a handful of people who are above you your

brain starts to believe that most people in the world are above you the bar is

raised almost impossibly high it seems like everyone is living close to perfect

lives and you're just here living an average one the more time you spend on

social media platforms like Instagram the lower and lower on the pyramid you

start to believe you are and that's where all of the mental health problems

stem from see the bottom of any social hierarchy is not a good place to be

this applies to humans and most other mammals if you're at the bottom of the

pyramid it means you are one of the least valuable people in the group it

means that nobody cares about you it means that you're expendable this

increases your levels of anxiety drastically it causes things like

insomnia panic attacks depression and addiction because you can't relax when

you're at the bottom it's like coming up second to last place on one of those

reality TV shows one more mistake and you're dead how can you relax and enjoy

life when you believe you're hanging off the cliff with just a couple of fingers

now of course this isn't real the truth is you're probably not at the bottom of

the social hierarchy most people around you live very average lives you're most

likely somewhere around the middle of the social hierarchy in your environment

where your brain doesn't know that because you're spending six hours every

single day in a fantasy world a world filled with models Lambos vacations and

endless smiles a world that literally no one can compete with even the most

successful people in the world can't compete no one is happy every single

second of their day as their pictures will like to have you believe and that's

why social media platforms like Instagram are ruining your life because

they force you into thinking you have to compete against a huge group of

imaginary people that you can never beat this episode was brought to you if the

[ROS in 5 mins] 043 - What is tf view_frames? - Duration: 5:20.

Hi My name is Ruben Alves, I am from Robot Ignite

Academy and today we are going to see what is "tf view_frames" and how it works.

For that we are going to use Robot Ignite Academy, which is the best platform if you

want to Learn ROS really fast.

I'm going to start here the "TF ROS 101" course to see how this tf view_frames work.

Let's wait until the system loads..., here we have it.

The tf view_frames is a tool that allows us basically to see how the frames of a robot

are connected.

If you list the topics, we may have here a topic called "/tf".

Ok, we still don't have it after running "rostopic list"

We don't have, so I'm going to launch a node, in this course TF ROS 101, in the chapter

Robot State Publisher, I'm going to run this code so I'll have the tfs of this robot, the

relation between the different frames, published on the /tf topic.

If we look here again, rostopic list, now we have the /tf.

If I want to see the structure of this robot, which parts connects to which parts, I could

use "rostopic echo /tf -n1", and I'm using the parameter -n1 to receive only one message.

Here we can see that we have all the frames.

If I maximize here, we have all the frames, what is the distance from one frame to another,

..., but we have a lot of information here, and it' not really easy to debug the tfs in

this way

So, if you want to see how the structure of this robot is, we can use a graphical tool

like RViz with "rosrun rviz rviz"

Let's open here the Graphical Interface and see this in RViz.

Ok, here we have it...

Let's add here the TF

And we should see the structure of the robot after changing the fixed frame to base_link

Ok, here we have all the information about the links on the robot.

We have so much information here that, in this robot, is almost impossible to identify

clearly.

We can "untick" the "show names", also untick the "show axes"...

Ok, here we have the structure of the robot, the graphical structure.

If you want to add something new to the robot, or see the frames names, as we can see here,

it's very difficult to see how the frames are connected in a graphical way, in this

robot, for example.

So, in order to clearly see the connections, we have the "tf view_frames" tool.

I'm going to run the command on the catkin_ws/src folder , so that the generated file is going

to be available here for download.

If we run "rosrun tf view_frames" a frames.pdf file is going to be generated with all the

information about how the links are connected.

The file was just generated here, we can download it, and ok, let's open this file...

If we look here, we have all the structure of the robot in this file now.

We can see that we have the "world" link, then we have the "base_link".

If we look here at the graphical interface again, the base_link should be around this

point,

And also cpu..., by looking here we see at the middle of the robot we see that links

divided in 3 parts.

We have one frame going up, one to the let and one to the right.

If we check here on the frames.pdf file we can see the same structure here, but with

all the names and relations.

For example, after the torso link we have the head_pan_link, which is the one that goes

up, we also have the left shoulder and right shoulder.

Additionally we have all the descendant links.

To summarize, the "tf view_frames" is a tool that allows us to see how the links are connected

in a robot structure.

This is the video for today, guys
