If you're looking to improve your memory… You've noticed your memory isn't what it used to be… Or you're simply searching for faster, easier ways to memorize — then THIS could be the most important website you'll ever visit.
But before I explain why, if you're like most people and it's your first time here, then you might want to know what this website is all about, and the slightly unusual story behind it all. So….
Here's the story…
My name is Ryan Levesque, and I'm the founder of this website. Growing up in a working-class family, after high school people thought I might go onto become a dockworker or shipping clerk alongside my dad…
But instead, with support from my parents I became the first person in our family ever to go to college, studied neuroscience, and managed to graduate with an Ivy League degree from Brown University.
There, as a student I was invited to teach in the neuroscience department for two years, and had my research on infant brain development published in the Pediatric Academic Society & Society for Pediatric Research medical journals.
But at 21, my life took a different direction when I moved to New York and spent two years working on Wall Street. And again at 23, when I moved to China so I could learn to speak Chinese fluently…
People wondered what the heck I was doing with my life until everything came together for me at 25, when I was offered half a million dollars to run a two-year investment deal in China — changing my life forever…
Which brings us to this website…
Because the reason I was able to go from working-class kid to ivy-league grad — taking on neuroscience, Wall Street, and China in a 5-year span — has nothing to do with being smart or working harder than the next guy…
Instead, one of the single biggest reasons was because at a young age, I was taught how to train my memory — a skill which enabled me to quickly learn a new field or subject and become proficient in a matter weeks or months instead of years…
And it's a skill anyone can learn, including YOU…
Now for me, it all started when I was a teenager and met my mentor, a retired college professor who moved in down the street…
Because he was the guy who showed me you could radically improve your memory by using unconventional techniques: Little-known methods most people don't even know exist. And stuff they definitely don't teach you in school.
You know, growing up I was never one of the smartest kids in class. But I was good at finding the shortcuts. So one day, I asked my mentor to teach me his memory system…
And that was a turning point in my life…
Because after learning that memory system, I went from a being a student who was burnt out spending 40 hours a week doing homework, to a kid who could retain vast amounts of knowledge and suddenly breeze through his classes with ease…
And that experience taught me two things about memory that changed my life:
First: I discovered an amazing memory has nothing to do with pedigree, ability, or natural intelligence. Instead, it's simply a skill — like riding a bike or playing cards. And anybody can learn it. |
And second: I discovered when you're armed with that skill, it gives you an almost unfair advantage in school, business, and nearly everything you do for the rest of your life… |

But all through my twenties, I felt embarrassed that a trained memory was my 'secret weapon'. Because it was nothing more than a system of techniques. Something I could coach or teach anyone who wanted to learn…
So for the longest time, I kept that secret to myself. Until a few years ago when my mentor passed away, and I started to seriously reflect on my life…
And that's when I realized I was making a terrible mistake.
Because there were other people out there like me, who could transform their life with this knowledge… Taught by someone with a background in neuroscience, who struggled as a student, but figured out how to use memory as a way to ahead in school and business…
So I decided to launch a little company called ROCKETMEMORY™ to teach people across the world how to radically improve their memory…
And in the past five years, over 26,000 people have enrolled in the courses and programs you see on this site — transforming their lives as a result…
And now that you know my story…
Here's my invitation to you:
As a first step to improving YOUR memory, I invite you to check out the ROCKETMEMORY™ Rapid-Results 10-Day Program.
This is our introductory home-study course that teaches you how to radically improve your memory, by investing just 1 hour a day for 10 days.
The program is backed by an unconditional 60-Day Money-Back Guarantee, which means you can test-drive the course for yourself, 100% Risk-Free.
In fact, here's the link to check it out now:
Now, as you might imagine, I passionately believe this is the best program available for anyone wanting to improve their memory.
But naturally, I'm biased :-) So please don't take my word for it…
Instead, I invite you to take a look and see what actual customers are saying about this program, by checking out some of the personal Success Stories people have allowed me to share with you.
Okay, I'll leave you with that for now.

I look forward to helping you improve your memory, reach your personal goals, and transform your life.
Let's take this journey together.
My warmest regards,

Welcome back to our series on building simple apps in Rust. Last week, we explored the Diesel library which gave us an ORM for database interaction. For the next few weeks, we'll be trying out the Rocket library, which makes it quick and easy to build a web server in Rust! This is comparable to the Servant library in Haskell, which we've explored before.
This week, we'll be working on the basic building blocks of using this library. The reference code for this article is available here on Github!
Rust combines some of the neat functional ideas of Haskell with some more recognizable syntax from C++. To learn more of the basics, take a look at our Rust Beginners Series!
Our First Route
To begin, let's make a simple 'hello world' endpoint for our server. We don't specify a full API definition all at once like we do with Servant. But we do use a special macro before the endpoint function. This macro describes the route's method and its path.
So our macro tells us this is a 'GET' endpoint and that the path is /hello
. Then our function specifies a String
as the return value. We can, of course, have different types of return values, which we'll explore those more as the series goes on.
Launching Our Server
Now this endpoint is useless until we can actually run and launch our server. To do this, we start by creating an object of type Rocket
with the ignite()
function.
We can then modify our server by 'mounting' the routes we want. The mount
function takes a base URL path and a list of routes, as generated by the routes
macro. This function returns us a modified server:
The queen of fighters 2.0 mugen ultimate. Rather than create multiple server objects, we'll just compose these different functions. Then to launch our server, we use launch
on the final object!

And now our server will respond when we ping it at localhost:8000/hello
! We could, of course, use a different base path. We could even assign different routes to different bases!
Now it will respond at /api/hello
.
Query Parameters
Naturally, most endpoints need inputs to be useful. There are a few different ways we can do this. The first is to use path components. In Servant, we call these CaptureParams
. With Rocket, we'll format our URL to have brackets around the variables we want to capture. Then we can assigned them with a basic type in our endpoint function:
![Website Website](https://qph.fs.quoracdn.net/main-thumb-27852733-100-XvZEwfk5L6T4uFitFgEyVqbwfalelJRi.jpeg)
We can use any type that satisfies the FromParam
trait, including a RawStr
. This is a Rocket specific type wrapping string-like data in a raw format. With these strings, we might want to apply some sanitization processes on our data. We can also use basic numeric types, like i32
.
This endpoint will now return '11' when we ping /math/5/6
.
We can also use 'query parameters', which all go at the end of the URL. These need the FromFormValue
trait, rather than FromParam
. But once again, RawStr
and basic numbers work fine.
Now we'll get '30' when we ping /math?5&6
.

Post Requests
The last major input type we'll deal with is post request data. Suppose we have a basic user type:
We'll want to derive various classes for it so we can use it within endpoints. From the Rust 'Serde' library we'll want Deserialize
and Serialize
so we can make JSON elements out of it. Then we'll also want FromForm
to use it as post request data.
Now we can make our endpoint, but we'll have to specify the 'format' as JSON and the 'data' as using our 'user' type.
We need to provide the Json
wrapper for our input type, but we can use it as though it's a normal User
. For now, we'll just return a string echoing the user's information back to us. Don't forget to add each new endpoint to the routes
macro in your server definition!
Conclusion
Next time, we'll explore making a more systematic CRUD server. We'll add database integration and see some other tricks for serializing data and maintaining state. Then we'll explore more advanced topics like authentication, static files, and templating!
