Content Marketing Tips for Nonprofits

(upbeat rock music) ♪ Everybody get up ♪ – Welcome back. Last we talked about content marketing and how nonprofits can use
the Garyvee content model. The beauty of Gary's
model is that it takes one piece of long form content and derives multiple pieces of micro content. If you did not get a chance
to watch last week's video we're gonna show it up here. Make sure that you click
the link in our description and watch it first. And then come back. So today, as promised, I'm
gonna share five specific examples of how your
nonprofit can use the Garyvee content model to start creating
and repurposing content. And make sure you watch until the end because we have a special
freebie that's gonna help you get started and put
everything we're talking about into action.

So let's look at five specific ways that your nonprofit can
use this content model. And let's assume that you
don't have any video content. Let's assume that you don't have a budget for a videographer. And let's also assume that
there's a relevant podcast that you've reached out to and they have agreed to
have you on their podcast so they can interview you
about a specific issue in your community or topic
that's of importance right now. And the great thing about podcasting is that the average length of a podcast is about 43 minutes. So if you remember from our last video we recommended that your long
form or your pillar content be 30 minutes or more.

So a podcast is a perfect way
to get that long from content that you need. And it's important to
remember that the purpose of content marketing is not
to talk about your nonprofit and not to try to get donations. The purpose of content
marketing is to add value and provide education so
that people can get to know, like, and trust your nonprofit. And when you do this
content marketing correctly, what you're gonna do is you're
gonna attract your audience and you're gonna retrain your audience. So in our podcast example,
when you go on the podcast, your goal is to provide
educational information. Perhaps you're gonna tell
a couple stories about people you're impacting in your community.

The goal is really to drive value. It's not to say, hey, here's
my nonprofit, look at us. Look at what we're doing. It's really to provide value to the people who are listening so that they can understand
at a deeper level what exactly your nonprofit is doing to impact the community and
how that's relevant to them. And at the end of the podcast, you'll have succeeded
if the people listening want to get more information
about your nonprofit. And this can be done
by them looking you up on social media and following you. Or opting in to your email list. So it's perfectly fine
to plug those things at the end of the podcast. Usually a host will say,
hey, how can people find you? And that's your opportunity to say, hey follow us on Instagram at
whatever your user name is. Or go to our website and
sign up for email list. That's perfectly fine. The idea is just to get that opt-in so that you can start to
have those conversations and deeper value with people.

Now let's get into the five specific ways you can use the Garyvee content model by being on a podcast. So the first step is to actually create the long-form content. So this is where you, or
maybe your executive director, or a board member, goes on to the podcast and is interviewed. So there's a couple things
that you can do here. The first is, you don't
have to worry about anything because the podcaster is
going to be recording this via audio for you. And if you are doing the
interview face to face, you could ask, hey, would you
allow me to bring a tripod? Where I can set up the tripod
and record our interview via video? And if you want to look at our video tips for using a tripod, make
sure to check out this video. But if you're not able to
record the video in person, the audio is fine. So what will happen is the podcaster will publish the podcast and then you're able to extract the audio from that podcast as
your long-form content.

And if you're wondering, hey
Jeanette, I don't know how to extract audio from a
podcast or from a video and you would like to
learn how to do that, leave a comment and if
we have enough people who are interested in
knowing how to do this, we can create a short tutorial for you. Okay, so that's our first example of how we can use the
Garyvee content method. Is that you create this long-form content, this pillar content. So the second example we have for you is once you have this 40 minute interview via audio or video, you can then take
specific clips from that.

So what you want to do is
export maybe a 30 second clip, or a two minute clip of something
that was really impactful really powerful, and make
that into its own audio. Now you can do this a
couple different ways so that you can have
an image that appears. You can use iMovie for instance,
where you put up an image and for that full two minutes of the audio that image will just show. And again, if you're
interested in learning how to do things like this, put a comment and we will follow up
with something for you. So you can see, just by
maybe having a 40 minute conversation with someone,
you might have 10 really good one minute conversational pieces that you can pull out of there. And instead of just
having one long interview, you now have four, eight, ten pieces of one minute audio clips that
you can use on social media. So the third example that we have for you is that if you have a quotable
moment in the interview, if there's something that's
said that's really impactful you can turn that into a quote.

So you could use Canva for
instance to find an image and then overlay the
text of the quote on it. We have a tutorial on how to do that. You can watch this video up here. We'll put a link in the description in case you want to know how to do that. So taking quotes from audio are another great way
to repurpose content. So the fourth example that we have for you is that once you have put
out your pillar content, you have put out your micro content, you start to see what
resonates with your audience, what people give the
highest engagement to, what kind of conversations are
going on around the content.

You can then create a
blog post or an article from this content. So maybe there was a
specific one minute clip that you put out and it was very relevant to what's going on in
the community right now and that's what got the most engagement. You can then turn that into
a written form of content that you can publish
via a blog or an article that lives on your website. And then you can redistribute
that by putting the link on social media so that
again, you're repurposing that content, it's just
a little bit fresher, a little bit newer. But that's another way you can use that same original content and drill it down into
smaller micro content. The fifth specific example
that we have for you is again, once you have
your community input and you understand what
resonated with people, you can send an email. And this email can link
to the long-form content and then you can also have
your highlights in text form. So think about this email
as a way to drive people to the long-form content, maybe
you put that audio on Facebook, maybe you put it on YouTube and then you can say, and here
are the highlights from it.

And you can list out the specific things that maybe came up in conversation if there's quotes, if there's statistics. And that gives people the opportunity to either do a quick
read or to dive in deeper if they want to. So hopefully now you
can see how if you get one piece of pillar content
or long-form content you can use that to
create 10, 20, 30 pieces of micro content. And when you're thinking
about content in this way it might start to make sense
to invest in a videographer. I think what most nonprofits struggle with is the idea of having videos and yeah that would be great. But they end up being
a one-time production and nothing gets extracted or repurposed.

However, if you were to do one
long-form video every month that was relevant, provided
value, provided education, helped you establish credibility. Then you could start to understand how you could take that, repurpose it and make that into, you
know, eight pieces of content so that you have two pieces per week, and that's a full month of
content for you on social media. So let's recap and I
want to share how this actually plays out in a donor situation.

So the first thing is you are
going to create your content to attract new donors. The second thing is that
someone sees your content they really like it and
they start to follow you on social media. The third step is that
you continue to provide content marketing that provides
education, value, and trust. So this is where people
really get to know you and you're continuing
your content marketing. So the fourth step comes
when you actually do put out an ask for volunteers or
donations on social media. The people that you attracted
have had enough time to see your content, to build the know, like,
and trust with you. And so now they're
ready to take an action. So this is where most
nonprofits fall short. Is they will get new
social media followers and half of the things that they post are related to asking for things. Instead of, providing
the value and education that they need to feel
connected, to feel trust, so that when you do ask,
they can take the action. So I hope that makes sense to you. If you had an ah-ha moment or
this does make sense to you, give us a thumbs up or leave a comment.

We would love to know what resonated. And now I would love to give
you some recommendations so that you can take this information and put it into action. So the first recommendation
is to look at the content you already might have,
the long-form content that can be repurposed. And once you have a list of that, if you have put it on social media, look at the engagement. Look to see which of
the content on your list is going to provide the most value based off of the prior engagements. The third step is then to make
a list of all of the ideas that you have to repurpose. So whether that's taking
it down into smaller clips, putting a quotable image,
creating an infographic, whatever those things are, make that list for that specific content. Of course the fourth thing
is to actually make the edits and then fifth or finally is to distribute that repurposed content
and see how it performs. See what kind of engagement you get. I think you'll be surprised that people probably won't remember
the long-form content that you put out beforehand and this just gives it a
much quicker, easier way to consume for people.

And if you would like to
get our quick start guide for repurposing content, we are gonna put a link in the bio so this is where you
want to click the link, put in your email, and
download the information. So wanted to do a quick
sidebar to show you how we use content marketing to earn our like, know, and trust with you. So it takes a lot of time and effort to put these videos together. But my goal is to provide value to you, provide education to you, so that you know that
we are the experts in nonprofit marketing. And along these videos
we have calls to action so that you can opt in or
follow us on social media. So if you remember just
from a couple seconds ago I invited you to download our freebie so that you can put content
marketing into action. So by doing that you are going to give us your email address and then we can start
to communicate with you.

I'm also going to
encourage you to subscribe to our YouTube channels
so that you don't miss one of our nonprofit marketing tips. And again, this is a call to action after we've provided value to you so that you can stay in touch with us and we can share more videos with you. Our ultimate goal down the line is to release our
donation-driven marketing course. And so this is something that
if you've liked our content if you want to get a deeper understanding of how you can leverage digital marketing to drive donations or
to get better results from your current digital
marketing efforts, there's gonna be an
opportunity down the line for you to purchase a course. Similarly with what you're doing once you provide some content
marketing to your donors there's gonna be an
opportunity down the line for them to make a donation.

So we hope that this makes sense to you. We hope we've provided value to you. And if you could, it would
really mean a lot to us if you give us a like or
subscribe to our channel so that we can see you next week..

Tesla’s Quest for Better Batteries

This episode of Real Engineering is brought
to you by Brilliant. A problem solving website that teaches you
to think like an engineer. Tesla has grown rapidly over the past decade,
when it became the first American automotive company to go public since Ford in 1956. The attraction towards Tesla is undeniable. Their cars are slick, their acceleration is
insane and perhaps most importantly, their brand represents a movement towards renewable
energy. Tesla has attracted thousands of well intentioned
people who want to play their part in saving the world, but there have been a niggling
questions on the minds of many EV owners and EV naysayers. When is that expensive battery going to need
to be replaced, and at what cost. As existing Teslas begin to age, and more
exotic and demanding models of Teslas come to the fore, like the Tesla Truck and the
Roadster 2. These issues are going to become more prominent, These batteries do NOT come cheap, but they
are getting cheaper. This chart shows the cost per kilowatt hour
for Tesla powerpacks, and the market average.

Both dropping dramatically as technology advanced,
and manufacturing volumes increased. But that storage capacity slowly creeps away
as the battery is used, slowly degrading the range of your electric vehicle. Tesla currently offers a warranty to all Model
3 owners that cover it below 8 years or 160,000 kilometres, whichever comes first. Guaranteeing a retention of capacity of at
least 70% when used under normal use. If it falls below that, they will replace
your battery for free.

Finding out what is considered normal use
is pretty difficult, but they seem to be reasonable with it going by customer satisfaction reports. From our graph earlier, it’s estimated that
Tesla is achieving a cost of 150$ per kwH of battery packs, so the 50 kWh battery pack
of the base model would cost around 7,500 dollars to replace, so they must be pretty
confident on those numbers. As a massive recall of the approximately 193
thousand Model 3s currently shipped would ruin Tesla. [3] Ultimately these batteries are unlikely
to drop below the warranties guarantee in those 160,000 kilometres, but even so improving
batteries is obviously just a wise business decision to retain those customers in future. This is just one of a myriad of factors that
influenced Tesla’s recent landmark acquisition of Maxwell Technologies for $218 million dollars. A rare Tesla acquisition that sets Tesla up
for not just cheaper batteries, but better batteries.

That will be lighter, have greater range,
and live a longer life. It wouldn’t be the first time an automotive
company underestimated their battery degradation. When the Nissan Leaf debuted in 2010, the
battery production they needed simply did not exist, and neither did the technical expertise
required to design battery packs. In those days lithium ion batteries cost about
400 dollars per kWh for laptop grade batteries, and up to 1000 dollars per kWh for ones with
the longevity needed for an electric vehicle. To minimise costs Nissan decided to start
production of their own batteries, and opted for a small 24 kWh battery, giving it a range
of just over 100 kilometres.

Suitable for city driving, and that’s about
it. But customers soon realised that this paltry
range was dwindling quickly. Within just 1-2 years of driving, the Leafs
battery capacity was dropping up to 27.5 percent under normal use. [4] Despite careful in-house testing Nissan
overlooked some crucial test conditions when developing their battery, and because of this
they made some crucial design errors. To learn why this degradation happens, we
first need to understand how lithium ion batteries work. A lithium ion battery, like all batteries,
contains a positive electrode, the anode, and a negative electrode, the cathode, separated
by an electrolyte. Batteries power devices by transporting positively
charged ions between the anode and cathode, creating an electric potential between the
two sides of the battery and forcing electrons to travel through the device it is powering
to equalise the electric potential. Critically, this process is reversible for
lithium ion batteries, as the lithium ions are held loosely, sitting into spaces in the
anode and cathodes crystal structure. This is called intercalation.

So, when the opposite electric potential is
applied to the battery it will force the lithium ions to transport back across the electrolyte
bridge and lodge themselves in the anode once again. This process determines a huge amount of the
energy storage capabilities of the battery. Lithium is a fantastic material for batteries,
with an atomic number of 3, it is the 3rd lightest element and the lightest of the metals. Allowing it’s ions to provide fantastic
energy to weight characteristics for any battery. But, the energy capacity of the battery is
not determined by this, it is determined by how many lithium ions can fit into these spaces
in the anode and cathode. For example, the graphite anode requires 6
carbon atoms to store a single lithium ion, to form this molecule (LiC6). This gives a theoretical maximum battery capacity
of 372 mAh per gram. Silicon however can do better. A single silicon atom can bind 4.4 lithium
ions, giving it a theoretical maximum battery capacity 4200mAh per gram. This seems great, and can provide increases
in battery capacity, but it also comes with drawbacks. As those 4.4 lithium ions lodging themselves
into the silicon crystal lattice causes a volume expansion of 400% when charging from
empty to full.

This expansion creates stress within the battery
that damages the anode material, that will eventually destroy it’s battery capacity
over repeated cycles. Battery designers are constantly looking for
ways to maximise this energy density of their batteries while not sacrificing longevity
of the battery. So what exactly is being damaged in the batteries
that causes them to slowly wither away? When researchers began investigating what
caused the Nissan Leaf’s rapid battery degradation, they began by opening the battery and unrolling
the batteries contents. They found that the electrode coatings had
become coarse over their life, clearly a non-reversible reaction was occurring within the cell, the
change was expected. In fact the chemical process that caused it
is vital to the operation of the battery.

When a battery is charged for the very first
time a chemical reaction occurs at the electrolyte electrode interface, where electrons and ions
combine. This causes the formation of a new layer between
the electrode and electrolyte called the solid electrolyte interphase. The name is exactly what it suggests, it’s
a layer formed by the liquid electrolyte reacting with electrons to form a solid layer. Thankfully, this layer is permeable to ions,
but not electrons. So it initially forms a protective layer over
the electrode that allows ions to enter and insert themselves via intercalation, but it
is impermeable to electrons. [10] Preventing further reaction with the
electrolyte.

At least that’s the idea under normal conditions. [11] The problem is, under certain conditions this
layer can grow beyond just a thin layer of protective coating, and result in the permanent
lodgement of the lithium that provides the battery with its energy storage. This process is not entirely well understood
and is outside the scope of this video, but we can identify some factors that increase
the rate of this formation. The expansion of the silicon electrode battery
we mentioned earlier causes the fracture of the SEI layer, exposing fresh layers of electrode
to react with the electrolyte. Charging rate and temperature can also accelerate
the thickening of this layer. NASA performed their own in depth study of
this effect, and released a report in 2008 titled “Guidelines on Lithium-ion Battery
Use in Space Applications” sharing their findings.

[12] The temperature that the battery is charged
and discharged at plays a massive role in the batteries performance. Lowering the temperature lowers chemical activity,
but this is a double edged sword. Lowering the chemical activity negatively
affects the batteries ability to store energy. Which is why batteries have lower ranges in
cold countries, but lowering the chemical activity also decreases the formation rate
of that SEI layer. This is on of reason the Nissan Leaf’s battery
lost a huge amount of capacity over just 2 years in many countries. Nissan performed most of its testing in stable
laboratory conditions, not over a range of possible temperatures. Because of this they failed to realise the
disastrous effect temperature would have on the life of the battery, and failed to include
a thermal management system, which is common place in any Tesla. This of course reduces the energy density
of the battery. Adding tubing, the glycol needed to exchange
heat, along with the heat pumps and valves needed to make a thermal management system,
not only adds weight, but it draws energy away from the battery to operate.

But it plays a vital part in maintaining the
performance of the battery. Nissan’s choice to not include a thermal
management system, even in the 2019 version, makes it a poor choice for anyone living in
anything but a temperate climate. Ofcourse, just cycling the battery though
it’s charged and discharged states is one of the biggest factor in degrading the battery. Every time you cycle the battery you are giving
the SEI layer opportunities to grow. Minimising the number of times a cell is cycled
will increase it’s life, and maintaining an ideal charge and discharge voltage of about
4 volts minimises any resistive heating that may cause an increase in chemical activity. This is where Maxwell technologies comes into
play. Maxwell has two primary technologies that
Tesla will be taking advantage of. The first is what Maxwell are known for, their
ultracapacitors.

Ultracapacitors serve the save fundamental
job as batteries, to store energy, but they function in an entirely different way and
are used for entirely different purposes. The fundamental difference between a capacitor
and a battery is that a battery stores energy through chemical reactions, as we saw for
lithium ion batteries earlier this is done through insertion into the crystal lattice. Capacitors instead store their energy by ions
clinging onto the surface of the electrode. This is a standard ultracapacitor schematic. On each side we have an aluminium current
collector with thin graphite electrodes on each, separated by an electrolyte and an insulating
separator to prevent the passage of electrons. In an uncharged state ions float in the electrolyte. When a voltage is applied during charging,
ions drift towards their opposite charge and cling to the surface, holding the charge in
place. When a device is then connected to the capacitor
this charge can quickly leave while the ions drift back into the electrolyte. The key limiting factor for ultracapacitors
is the surface area available for this to happen, and nanotechnology has allowed for
amazing advances in the field. This is what the inside of a ultracapacitor
looks like, it contains hundreds of layers of these electrode pairs.

But even with this enormous surface area,
ultracapacitors simply cannot compete with batteries when it comes to energy density. Even Maxwell’s best ultracapacitors have
an energy density of just 7.4 Wh/kg [13] while the best guess for Tesla’s current energy
density is about 250 Wh/kg. Counter to what corporate owned tech channels
may tell you, ultracapacitors are not intended to be a replacement for batteries. They are intended to work in conjunction with
batteries. Ultracapacitors strength is their ability
to quickly charge and discharge without being worn down. This makes them a great buffer to place between
the motors and the battery. Their high discharge rate will allow them
to give surges of electricity to the motors when rapid acceleration is needed, and allow
them to charge quickly when breaking. Saving the battery from unnecessary cycles
and boosting its ability to quickly provide current when needed for acceleration. This is going to be a massively important
technology for two upcoming Tesla vehicles.

The Tesla Roadster, which will boast an acceleration
of 0-60 in just 1.9 seconds, which a normal battery would struggle to achieve the discharge
rate needed without damaging itself. The second vehicle is the Tesla Truck. I have made a video in the past noting that
the Tesla Truck is going to be limited in its range and cargo hauling ability as a result
of the heavy batteries it will need, as trucks are limited in weight to about 40 metric tonnes
in most countries. This ultracapacitor technology will boost
its ability to regain energy from breaking significantly, and thus allow its battery
capacity to decrease, in turn allowing the truck to swap batteries for cargo. The second technology Maxwell has been toting
as their next big breakthrough is dry coated batteries. [9] This is a manufacturing advancement that
Maxwell claims will reduce the cost of manufacturing. A factor Tesla has been working fervently
to minimize with the growth of the gigafactory. So what are dry coated batteries. Currently in order to coat their current collectors
with the electrode material Tesla, in partnership with Panasonic’s patented technology, must
use first dissolve the electrode material in a solvent which is then spread over current
collector, both are then passed through an oven for drying, where the solvent evaporates
leaving just the electrode material behind.

This adds cost of the manufacturing procedure
as the solvent is lost in the process, and the baking process takes energy. On top of this the solvent is toxic, so removing
it from the process would benefit the environment. Maxwell instead uses a binding agent and conductive
agent, which I assume will work similarly to electrostatic painting. Where a metal being painted will be given
a negative charge, while the paint will be given a positive charge as it is sprayed attracting
it to the metal where it will cling to it. This painting process also eliminates the
solvents needed in paint. In this paper, published by Maxwell technologies,
they detail how their dry coating manufacturing techniques could result in a high energy storage
capacity of the electrodes, due to a denser and thicker coating. Resulting a potential increase in battery
capacity to 300 Watt hours per kilogram, 20% up from our best estimates of Tesla’s current
specs.

Only time will tell if this claim can be realised
at an industrial scale. Perhaps, more importantly to Tesla, they now
own this manufacturing technique. Currently Panasonic owns the manufacturing
process for Tesla, there is a literally a line of demarcation in the gigafactory separating
Panasonic and Tesla, denoting the point at which the ownership of batteries transfers
hands. Having to buy their batteries from Panasonic
adds cost, that Tesla will want to avoid in future and this step could allow for full
vertical integration of their battery manufacturing. Thereby making electronic vehicles more affordable
to the everyday consumer. All of this technology is powered by incredibly
smart engineers working to solve really interesting problems, and with so much focus on battery
technology across the entire tech industry there’s a high demand for qualified engineers. For anyone looking to build or advance their
engineering career I’d highly recommend Brilliant. Brilliant recently introduced a new feature,
called “Daily Problems”, which will present with you with interesting scientific and mathematical
problems to test your brain. Like this one, that teaches you about rolling
resistance. One of the ways vehicles lose energy.

It takes you through a short explanation of
rolling resistance, giving you the framework you need to rationalise a question they pose
to you. Here the answer is pretty simple. Rolling resistance occurs from the loss of
energy to the ground and wheels, so by driving from gravel to concrete we lose less energy
to the ground. If you answer a question wrong though, you
can get help by discussing the solution with thousands of other users.. Allowing you to learn from your mistakes. Brilliant even have an app that you can download
to play these brain teasers on your morning commute. If you like the problem and want to learn
more, there’s a course quiz that explores the same concept in greater detail. Daily problems are thought provoking challenges
that will lead you from curiosity to mastery one day at a time. So what are you waiting for? Go to brilliant.org/realengineering/ and finish
your day a little smarter. And the first 500 of you to do so will get
20% off the annual subscription to view all problems in the archives.

Hyperloop Explained | The B1M

billed as the fastest way to cross the surface of the earth Hyperloop represents the greatest leap in transport infrastructure for generations with passengers sitting in pots that travel its airline speed through pressurized tubes using electric propulsion and magnetic levitation the concept promises to slash geni times between major cities from several hours to a matter of minutes whilst it may feel like science fiction Hyperloop is now on the cusp of becoming a reality this is the story behind the concept that's about to revolutionize our world [Music] Hyperloop was first conceived in 2012 by Tesla and SpaceX founder Elon Musk in a white paper released the following year musk set out his vision for a futuristic super high-speed transportation system they would see passenger pods move through a partial vacuum in steel tubes addressing the two key factors that slow down conventional vehicles friction and air resistance exploring a potential route between Los Angeles and San Francisco must believe that his concept could slash the eight hour bus ride four-hour train journey and convoluted three-hour air travel experience between the two cities to just 30 minutes under Musk's first Hyperloop proposal he suggested that compression fans would move air around the passenger pods to minimize drag and create air bearings beneath them floating them off the surface of the tubes it should be noted that Musk's early Hyperloop concept is not a million miles away from isambard kingdom brunel atmospheric railway that ran between Exeter and Plymouth in the UK from 1847 to 1848 that system moved carriages with pressurized air the air was extracted from a pipe that ran between the rails by pumping stations situated roughly every three miles along the route creating a vacuum a piston contained within this pipe was connected to the Train which pulled it forward despite its initial success the leather flaps that made the vacuum pipes airtight soon began to fail causing air to leak from the system and Brunel railway was abandoned with an estimated price tag close to six billion US dollars Musk's first Hyperloop concepts never came to fruition but the impressive idea and potential to link cities in such a direct way sparked intense interest from inception mosque had always stated that the concept of Hyperloop would be open-source and he actively encouraged others to come together and develop the necessary technology independently from his involvement this led to the formation of several startups and student teams developing various aspects of Hyperloop technology with varying degrees of success now several fully fledged companies are making significant strides to bring Hyperloop systems into reality Piper leave transportation technologies or HTT are making aggressive advancements and recently constructed a full-scale test track in France but the clear leaders of the pack in the current standings are virgin Hyperloop one virgin Hyperloop one are on track to achieve their bold ambition of bringing a Hyperloop system into operation by 2021 originally formed in 2014 as Hyperloop 1 the company was rebranded following a significant investment from Sir Richard Branson in 2017 deviating slightly from Musk's original plan virgin Hyperloop ones technology combines two basic principles the first is magnetic levitation or maglev a technology already used in mana rails to lift the passenger pods and move them along their rails magnetic levitation uses two sets of magnets one to repel the Train from the track and lifted upwards and the other to move the floating train along the track at considerable speed with reduced friction the second principle is the use of a low pressure vacuum sealed environment for the passenger pods to travel through by removing most of the air from the tubes and having no contact with the ground the pods face little to no resistance as they move air pressures inside the tube are equivalent to flying two hundred thousand feet above sea level such an environment enables the pods to reach speeds of over 760 miles per hour using very little energy by virtue of being in a tube the system is protected from the weather and can operate in almost any climatic conditions virgin Hyperloop one's system is controlled by advanced software that ensures acceleration and deceleration occurred gradually going relatively unnoticed by those traveling inside having built a 500 meter track in the Nevada desert virgin Hyperloop one have carried out several tests focusing on individual aspects of the system and a complete full scale systems test in May 2017 the propulsion braking levitation and vacuum systems are all performing well and the team have achieved a top speed of over two hundred and forty miles per hour to date to inform their plans for developing a fully operational network that is affordable for all virgin Hyperloop one launched a global challenge to find the routes best placed to benefit from Hyperloop technology with over 2,600 entries the field was reduced to just 35 potential locations with each entry enjoying strong support from governments and urban plans with 10 winners across five countries virgin hyper live one are now working in partnership with each of the locations on how best to deliver the Hyperloop technologies in live networks in February 2018 the firm unveiled their first prototype passenger pods for the Dubai to Abu Dhabi route a network that would drastically slash the car travel time between the two cities from 2 hours to just 12 minutes the advantages of Hyperloop are considerable like train stations Hyperloop stations called portals are planned to be located within inner-city areas with easy links to existing transport infrastructure this gives Hyperloop systems a distinct advantage over air travel where airports tend to be located beyond city limits with fewer accessibility options additionally the system is being developed to function on a turn up and go principle without a lengthy check-in process and with accelerated advanced security checks another clear benefit is its speed if Hyperloop could significantly reduce the travel time between cities it could be possible to live in a completely different city or part of the country from where you work with a commute notice similar in length to the one you perhaps take today this opens up a wide range of housing and employment opportunities with people no longer having to live close to where they work it could also take pressure off our cities where infrastructure is often still catching up with development and warehouse prices have become unattainable for most with speeds rivaling aircraft and nine of the top ten busiest errors in the world being domestic pipe loop has the potential to completely revolutionize the way we live work and travel a Hyperloop system requires very little energy to propel pods through its tubes as the vacuum environment poses little resistance as such the systems could be powered by renewable technologies such as solar and wind offering a considerably cleaner alternative to air travel when you consider the prospects of people being propelled in tubes across the Earth's surface at near supersonic speeds there are a number of questions that instinctively jump to mind perhaps the first is the impact of a potential break or breach in one of the tubes possibly as the result of an earthquake or external impacts virgin high believe one explained that they have addressed this by constructing thick steel tubes that are extremely difficult to puncture or break additionally the tubes are engineered to withstand changes in pressure and air leaks while maintaining their structure integrity theoretically a sudden influx of air into one of the tubes would simply slow the pods down due to the increased air resistance the pods could then be directed to the next portal via an auxilary power boost there is also the ability to section off parts of the route and to repressurize sections where significant emergencies occur and all pods are expected to be fitted with emergency access externally Hyperloop systems will largely travel on elevated seismically designed pylons that are able to move and flex independently of one another minimizing damage in the event of a major ground shift sensors along the route would instantly report issues to the systems control center in answering the natural safety concerns raised virgin Hyperloop one also point out that millions of people already travel at high speeds in metal tubes every time they take a flight and that numerous concerns surrounded the use of jet aircraft when that mode of transportation first came to prevalence while the idea of Hyperloop may seem far-fetched when you consider the industrial progress made in the past 200 years the current rate of technology adoption in our societies and the significant advances being made by hope elite companies around the world this incredible new transportation system looks sets become part of our everyday lives in the very near future if you enjoyed this video and would like to get more from the

Lean Body Sculpting System An innovative combination of leading technologies 1

If you are frustrated by the number of books on your scale, I have good news for you. There is a new generation of fitness product that is based on the concept that on what really matters is not your weight, but your body composition My name is Robert Ferguson and I am a nutritionist and certified coach. I have accompanied stars and professional athletes for more than 20 years.

and I will share the secret behind these beautiful bodies. It all starts with the fat-muscle ratio in a body. And that can make a very big difference in the composition of your body. That's the reason why pound for pound muscle mass is much denser and takes up less space than fat. This is what we call body composition This is the reason why two people with the same height and weight can have two different sizes and all this is due to their fat-muscle ratio. So now you're going to think I'll probably want to talk to you about a diet or a training program, but I'm not going! Modere to create a new generation of fitness product that focus on weight loss and body composition. It's an innovative combination of technologies that is also a world first that accelerates the loss of bad fat which reduces the size of the fat cells, which reduces the formation of fat cells, increases muscle mass accelerates the metabolism burns more calories therefore encourages a thin body composition This system is called the Lean Body Scupting and is a revolutionary system who will help you transform your body.

no matter what your starting weight or your level of training. It all starts with Trim, a product with two advanced technologies. CLA accelerates fat loss COLLAGEN / HA MATRIX technology that helps build muscle mass and improves the appearance of young, healthy skin. CLA or conjugated linoleic acid not only helps the metabolism to burn fat but also helps the transport of fat in the blood which makes the absorption of fat is deminerate, so there is a reduction in the size of fat cells as well than a decrease in the formation of fat cells. In the Trim, you get CLA derived from plants with the perfect amounts, 3.4 grams. This quantity is the best and has been demonstrated by clinical trials. Even if your goal is to lose fat first, all of this can come with unwanted side effects. Loss of fat can cause skin effects by wrinkling and aging And all this is caused because with age we start to lose collagen and HA two important components for healthy skin Collagen / HA Matrix technology is patented several times, won awards and has been clinically proven to improve the appearance of skin helps joints to be more flexible / flexible in addition to helping muscles during training.

So you will not feel that more fit, more active and thinner, but your skin will be firmer and younger. The only thing you need to do is take a spoon at the Trim table once a day The trim is sugar free and the taste is great. Burn is another component of the Lean Body Sculpting System. This science is thermogenic, in addition to waking up your metabolism, reduces cravings and increases energy. Fucoxanthin is a powerful ingredient for fat loss that is extracted from coastal algae. Burn gives you 3x more Fucoxanthin than other popular brands and is combined with berberine and with chromium. This thermogenic blend will help you maintain a healthy level of sugar in your blood and bring your body into fat burning mode all day long. And to complement the Lean Body Sculpting System, Activate naturally makes a detox of your body in just 3 days. It is a perfect supplement for your weight loss. Activate is formulated with organic aloe vera, the same thing we use to relieve sunburn.

But you may not know that Aloe Vera is recognized to eliminate toxins from the digestive tract. This product that cleans naturally is combined with apple pectins that helps regulate your system and psyllium seeds to add fiber. You only have to pour your Activate sachet in a glass of water once a day for 3 days while eating normally. Activate is sugar free, vegan and GMO free. Bein eating well and moving are essential elements in all weight loss programs The Lean Body Sculpting System will optimize your metabolism to fat loss in addition to encouraging a thinner body composition for a total transformation of your body You never look at weight loss again in the same way.

The Lean Body Sculpting System is much more than just weight management and is available only at Modere.

Inside China’s High-Tech Dystopia

There's no disputing that Shenzhen has become one of the most important places in the world of tech. Nowhere else has quite as potent a combination of tech know-how, cheap manufacturing costs, and sheer speed. But it goes further than that. Living in Shenzhen is in many ways like living in the future. And not necessarily a utopian future. More like the other kind. Consider Zowee. Zowee operates a factory much like any other in Shenzhen. They make cheap smartphones and other electronics. Like other top manufacturers, they've built a complex where workers can live right beside the factory line, work around the clock for a couple of years, and hopefully buy a better life for their families back home. The factories here are clean, and the work is precise. But things are changing quickly in a way that does not favor the common man and woman.

All the rest of these lines are staffed by about 80 people, but right here there are new machines coming online that are going to build a smartphone end-to-end completely by robots. The end goal of something like this is to get the quality of the products higher, to bring costs down from less labor, and ultimately to keep China as the manufacturing hub of the world and fend off low-priced competition from places like Southeast Asia. The factory of the future looks like this. It's a closed off loop where robots pass components among each other, and finished products pop out at the end. All those workers have been replaced by one lonely final inspector. It's a strong sign that the future of Shenzhen is less for these guys… …and more for these guys. Zowee actually builds these automation machines itself. Behind me are some of China's best and brightest engineers, hard at work building the machines you see out on the floor today, and the ones that are coming tomorrow that are going to automate the entire factory line.

Nowhere will face more turmoil than Shenzhen as the robots rise and send millions of workers to the unemployment line. But it's not just the working class that's facing a dark future. There are dystopian innovations that seem to touch every facet of life here. I ran into one example of this while attempting to rehydrate. After some investigation, I discover what's going on here, and it has to do with these things: QR codes. You know the drill. You scan the code and something pops up on your phone, like a promotion or discount. America laughed these things off years ago, but here, they run the entire economy. Cash and credit cards are history. Instead you scan QR codes to pay for everything: restaurants, groceries, even buskers. On the surface this is all good. It's the easy, convenient mobile payment system of the future. But there's also a dark side.

The Chinese government can peer into the two dominant payment systems, AliPay and WeChat, as it sees fit. It's already started tracking behavior as part of a plan to rank citizens and measure how good and obedient they are. The tech revolution may have brought prosperity to Shenzhen but it's also brought more and more insidious intrusions into people's lives. To dig deeper into life under the Chinese deep state, I've assembled a team of extraordinary foreigners who work at tech startups in Shenzhen. Hopefully a few beers will encourage them to open up about their thought crimes. Living in a very tightly regulated Communist country – does that bother you, or you don't care? The presumption at least that I got before I came from Australia was sort of like moving into a sort of like a militarized state, like things are going to be really intense. But like, you take a beer, just like walk down the road, hang out in the park, fine.

Do that back in my hometown in Australia, like, straight to the cop-house. But then, play spikeball on the grass, and then all of a sudden the cops come and stop you. Well and you got, you jaywalked and you had facial recognition? I actually got this. So I was jaywalking in Nanxian. And all of a sudden I got a fine to my WeChat. Was it instant? It was about 20 seconds after, I guess. I had money in my balance and it just went straight out. This is just for the one thing – it just came straight out. Didn't even authorize it. That's crazy. It's true. Try to jaywalk in certain parts of Shenzhen, and the government's facial recognition will spot you. There's even a board of shame, showing the faces of recent offenders. I'm surprised and very very worried that they have your face in the facial recognition – like, the facial recognition system.

But they have everyone's though. When you go across the border they take that picture, exactly, yeah. So it's all in the system, they know where you are. That's scary. It gets even scarier. Because big brother is watching what you do online too. Most of the websites we know and love are blocked in China, replaced with Chinese equivalents that the government can monitor: a sort of mirror universe internet. I asked my friend Diane, a Shenzhen native, to help break this down. Appropriately enough, she took me to this restaurant staffed entirely by robots. That's some gnarly-looking chicken. Is that chicken? Mmm… robot food. I wanted you to help you out with one thing. So if I sorta call out a U.S. tech company, can you tell me the Chinese equivalent? Because you know, you can't get Instagram or anything here, so. Let's do a few. So Google would be… Baidu. And Amazon… is like, both JD.com and also Taobao OK. And, and, um. YouTube? Youqu. Youqu, Iqiyi. Facebook? Facebook we have WeChat. Yeah. Do you feel like you're in a different universe? All the online stuff is such a big part of all our lives.

And it seems like China has created its own world. Yeah, that's definitely like that. But like I said, for for like Instagram, I was surprised to see even – Instagram got banned from China, but all the young people, they're there. Still go. Yeah. It turns out it is possible to access the freedom-loving internet here, via what's called a VPN: an alternate internet connection that bypasses the government's blocks. And you don't get in trouble if they see that you're on the VPN all the time? For personal use, I don't think that's that big of a deal, yeah. The future will be interesting for how the different worlds are collaborating together. Yeah, and definitely the young generation, they're not like just, oh, I'm satisfied just to kind of stay inside.

Yeah, they're more curious. I came to Shenzhen hoping to find some kind of ground truth, a clear picture of what China's growing tech prowess will mean for the rest of us. Honestly though, I'm as confused as ever. The city is full of energy, desire and creativity. But exactly how those traits are channeled in the years ahead remains an open question. My hope is that the best parts of our human nature get a chance to thrive, and that 1984 can wait a few more decades to arrive. And on that note, I leave you with this dashboard dog. Because it's obviously good and pure and very happy.

How to prepare for Technical Interviews

*keyboard sounds* Hey everyone what's happening? It's Mayuko Today, I'm going to be going over some of my tips and tricks for how to study for the technical interview Which is a typical part of the software engineering interview process. Whether you're interviewing for an internship, or a full-time job, I hope these tips will help you ace your next technical interview so when interviewing for a software engineering job There's usually three stages: the phone screen, the technical phone interview, and the on-site Today, we're going to be focusing on the technical interview Which is a core part of the technical phone interview and the on-site I might make another video for the other parts But my advice here actually applies pretty generally to all of the stages—so hopefully they help Alright, ready? Here we go! My first tip is to study and this might sound weird or dumb or cliche, but really study for your interview Companies use a technical interview as a part of the standard interview process in order to assess your technical ability Ideally the problems that you encounter in the technical interview are the types of problems that you would encounter IRL (In real life) at this job because that gives a true measure on how you would do should you work there.

And for companies that don't do this. I'm looking at you. What are you really gonna learn from asking someone: How many ping-pong balls fit into an airplane? Now, all of that aside and sometimes Those are the types of questions you might get what you're called brain teaser questions The technical interview is there to assess how you solve problems Anyways here are my favorite resources for studying for technical interviews the first is cracking the coding interview now I know y'all have heard me talk about this before but cracking the coding interview is basically the Holy Bible of studying for technical interviews.

I have my copy right here which is the fifth edition and I wanna say? Yeah, it's the fifth edition and it's it's got all my highlights and stuff in there But this is so useful when it comes to setting for a technical interview it includes refreshers for computer science concepts and a bunch of practice problems with answers in the back This book is written based on the technical interviews from big companies like Google, Apple, Amazon and Microsoft A new edition is released every year so that it's always kept up to date That said if you don't get the latest edition, it's not such a big deal but it is cool to see the latest editions of stuff because they're going to reflect What the interview process is like at those companies currently.

I'll leave a link to buy the book down in the description box below. The second tool I use is called LeetCode
— it has thousands of crowdsource interview questions that you can work on in an online editor, so it'll give you a problem And then you can code out your solution and it runs it against a bunch of tests so you can see whether your solution works or not The problems vary in difficulty and you can use what programming language that you're most comfortable with I use this hand-in-hand with cracking the coding interview.

The fact that it's an online editor really mimics a technical phone screen and it gets me into the right mindset So my next tip is to study for the specific technology. Now I'm leaving this at like a 1.5, because this may not apply to everyone. If you're interviewing for a role specializing in a specific technology or a stack— And you'll know this by looking at the job description then you're definitely going to want to study the concepts associated to that technology or stack For instance, I'm an iOS engineer and so when I'm studying for interviews I'm brushing up on core iOS concepts and frameworks like UI kit for example my My friend and web engineer friends will brush up on things like JavaScript and react instead Using this knowledge as part of your technical interview will exemplify your level of mastery with this technology It will give companies a better sense of where you stand in terms of your experience Okay, so my next tip is to study with a buddy This is actually the most important piece of advice that I have for you in studying for a technical interview We mentioned a little bit about this in my Q&A with Jarvis video, but when companies are giving you a technical interview, They're not as interested in you having the right answer as they are seeing what your thought process is like.

"But Mayuko, didn't you just say you needed to brush up on core technical concepts in order to do well in your technical interview?" Well, yeah! But the way that I think about it is that you're better equipped to solve these problems if you have the right tools in hand Those tools in this case are being able to recall computer science concepts and frameworks in order for you to solve your problem well! Imagine if someone told you to build a table without any tools you're much better off successfully figuring out how to build the table if you have those tools right? So once you have your technical chops back up to snuff from studying then find a buddy to do a mock interview with you they can pretend to be the interviewer and give you the interview problem.

You can practice thinking out loud as you would in a real technical interview and the act of doing this will just get you so much more comfortable with articulating your thought process Now, not articulating your thought process in a technical interview is actually where most interviews go awry If you're not explaining what you're thinking then your interviewer has no chance to course-correct you towards the right direction And they actually don't get very much information or insight into how you solve problems which is exactly what they want to find out in this interview! So, try this out with a buddy and at the end of your mock interview, ask your feedback on what you did well and what you didn't do well. you can take this feedback as ways to improve your next mock interview or for your actual technical interview My last piece of feedback is to relax and you're gonna be just fine I know that interviews are scary and talking to an interviewer to prove your worth is downright terrifying But know that you are going to own this! If you (1) study and (2) practice with a buddy, then know that you can walk in there with confidence because you've prepared for your technical interview! Do whatever it is that you need to do in order to get yourself amped and ready for this interview! I personally like power posing for two minutes right before my interview Also remember that everything is a process and so there might be some rockiness along the way Interviews can be really competitive There could only be one spot, but a thousand applicants But know that preparing and going in there and giving it your all is so much better than not trying at all Do or do not there is no try With all things in life remember that each bump in the road is a new lesson that can be learned that you can take with you next time so regardless of the result, I highly recommend you follow up with your interviewer if you can to ask for feedback on what you can improve on they're usually more than willing to help on this and you can take these lessons with you for your next interview Just remember to take a deep breath and stay positive during your interview.

Be polite, inquisitive and thoughtful and you're going to do great! I know that you can do this! So these are my tips for how to study for a technical interview Remember to study and sometimes for specific technologies Practice with the buddy and remember that you're going to do great! Leave a comment down below for your favorite interview tips and tricks I'd love to hear them Also, if you know of someone who's interviewing for a job right now, then please share this video with them And don't forget to give this video a thumbs up if you liked it and subscribe to my channel for more videos Good luck on your interview, and I'll see you next time. Bye!.

How San Francisco Is Becoming A Zero Waste City

did you know that the urban waste produced from cities around the world is enough to fill a line of garbage trucks stretching more than 3,100 miles that's a distance from Florida to Washington every day and things are only expected to get worse thankfully some cities such as San Francisco are paving the way and trying to change the way we think about trash San Francisco plans to become zero waste by 2020 which is a pretty ambitious but awesome goal and this is the main nerve center for all of the city's recyclables this is where everything ends up to be sorted and processed what is zero waste it's an idea and it means sending next to nothing to landfills or incinerators in 2009 the city passed a law requiring residents and businesses to sort their waste into recyclables compostable and landfill trash Recology is the private company that handles it all when I started at Recology 23 years ago the recycling rate was around 38% today we've more than doubled that so far San Francisco has diverted 80% of it to waste away from landfills and its success has been getting global attention government representatives from all over the world visit this facility to learn about how they might be able to replicate what's being done here what is the current method of waste management or recycling in your town what we have a lot of in Denver is excellent incineration where you will burn the waste do you think that you might implement some of what you've learned one thing that we have heard a lot is a the value of composting we don't do that a lot so maybe we will go home and do more composting San Francisco now collects 650 tons of food scraps yard trimmings and other organic waste every day that material is brought here to be turned into compost this is one of the most modern composting facilities in North America ok so you can see a bunch of stuff here that people have thrown away mostly like wood here a shoe this flip-flop yeah there's that what's up with shoes okay well there's seven billion people on the planet so there's a lot of shoes we're in a culture here in California where people are moving very quickly and so people make mistakes so we get the the things that are not supposed to be here we get them removed right away right at the beginning after the waste is ground up and screened for plastic and other bits of trash the organic matter leftover gets watered and aerated a piping system then filters out dangerous greenhouse gases produced by microbes in about 60 days the compost is complete and sold to local organic farmers and vineyards how does composting help the environment composting keeps materials out of landfills it returns nutrients to farms it reduces the production of very potent greenhouse gases it attracts and retains water like rainwater I mean it's smell like hell but it's actually very beautiful what you're describing here you know people's food scraps which might otherwise the waste comes here to essentially feed these farms and produce new crops well from this facility more than 300 vineyards have received the compost and applied it to their vineyards farmers are using the compost to grow cover crops that pull carbon out of the atmosphere and return carbon back to the soil this is one of the best things we can do in an effort to slow down climate change people have really heard a lot about environmental problems they want to hear now a lot more about environmental solution how much recycling and composting is there in your town let us know in the comments below and be sure to watch this next episode about a woman who already lives a zero-waste lifestyle two ears of trash in this tiny village are my values are having a really low environmental impact I have to live like I want that and so that's why I decided to change my lifestyle thanks for watching and please subscribe to seeker stories to see new videos every week

What is RAID 0, 1, 5, & 10?

Storage is a very important part of the fault tolerance mechanism. If the company’s information is damaged as a hard disk For reasons such as loss of data, it will have a serious impact on the company's operations. That's why we have to make sure that when the hard drive is damaged, the data will Will not be lost. One of the good ways is to use RAID technology.

The RAID name is "Fault-tolerant Disk Array". When deploying RAID, the data will be copied to multiple disks for storage. When the disk is damaged, the data will not be lost. There are currently four common RAID levels, RAID 0, RAID 1, RAID 5, and RAID 10. In fact, RAID 0 does not have a fault tolerance mechanism. In fact, RAID 0 should not be at all. a type of RAID, because RAID 0 not only has no fault tolerance mechanism, it even Increase the risk of data loss. Because in RAID 0, the data is not copied and stored on each hard disk, but scattered or Segmented in 2 hard drives. So if one of the hard drives is damaged, or if you can’t open it and destroy one of the hard drives, All information will be lost.

So the only reason you want to use RAID 0 is because it accesses quickly. Because when you can control 2 hard drives at the same time, Accessing data will be especially fast. RAID 1 has a fault tolerance mechanism. In RAID 1, the data will be copied to more than one hard drive, so the second hard drive will have The same information as the first hard drive. All when a hard disk is damaged, for example, the hard disk is burned by laser light.

The information will not be lost because another hard drive has exactly the same information. Next, let's talk about RAID 5 If you want to use RAID 5 technology, you must have at least 3 hard drives. RAID 5 may be The most commonly used RAID technology because access is fast and Can access a large amount of data. In RAID 5, the data is not copied, but is scattered or segmented. In each hard drive. In addition to the information, there is another very important Information is spread on the hard drive, that is "Number of bits".

The number of bits is used to reconstruct the data when the hard drive is damaged. But RAID 5 has a problem because there is an equivalent The capacity of a hard disk is used to store the "bits", which will result in a hard disk. The total access is reduced. For example, these 4 hard drives have a 1TB capacity. This has a total of 4TB. But if RAID 5 is set up, the total hard disk access will be left. 3TB, because there is equivalent to 1TB of capacity The number of bits. Finally, there is a so-called RAID 10, RAID 10 is basically just like the name, it is a combination of RAID 1 and RAID 0. At least 4 hard drives are required. In RAID 10, there is a set of 2 hard drives for RAID 1 to store data from the main hard drive. Then the two sets of hard disks are then distributed in a RAID 0 manner.

Therefore, RAID 10 has the fault tolerance of RAID 1, and also has a faster access speed of RAID 0. But the problem with RAID 10 is that you can only use half of the hard disk storage space. So if you use 4 hard drives to group RAID 10, then you can only use the equivalent of 2 hard disk spaces.
