Is Your Blogging Worth The Effort? /4 Tips to Measure Content Marketing ROI
By: Tuğçe Gör
Tags: Google Analytics, Blogging Tips, Marketing, Blogging, Digital Marketing

We transcript this video to make you quickly learn to measure the ROI of content marketing.

Content marketing is helpful to generate you traffic.

Let’s talk about how to measure the ROI of your content marketing!

How to Measure the ROI on Content Marketing?

So what’s the first thing you need to do?

1. Sign up for Google Analytics

Google Analytics is a free tool from Google, that’s right, for free. It’ll tell you how much traffic you’re getting.

See, the beautiful part is, not only will Google Analytics show you how much traffic you’re getting and also it can tell you how many conversions you’re generating.

2. Track Your Conversions

Instead of goal tracking, and within Google Analytics, you can identify how much each lead or each sale is worth to you.

Every time you generate a sale from your content marketing, it’ll show you that this is how much revenue you’ve generated.

Then you could match that up with how much money you’ve spent.

If you spent a lot of money and you’ve generated even more money, then you’re good. If you’re spending $10,000 a month but you’re only generating $1000 a month, something’s kind of wrong.

3. Be Patient

It takes a year before content marketing does well.

Yes, within six months you will see results, but within a year or after a year more so, that is really when things start kicking in, so you have to be patient.

If you wanna be cashflow positive in the first twelve months it’s probably not gonna happen.

If you started five to ten years ago, sure, but it’s way harder to get rankings in Google and it’s harder to get traffic from social sites like Facebook, so you need to give it time.

4. Check Out Results on Tools

If you’re trying to generate an ROI from content marketing, go check out SEMRush or Ahrefs.

They’ll tell you how much traffic you’re generating and how much it’s worth, similar to Google Analytics but they give you a dollar estimate, and they tell you, other people, who are buying traffic for your keywords, how much they’re spending.

We call it the power of content marketing and for ROI, you just have to be patient and give it a year.

Blogger to Author Part 11: The Conclusion
By: Cody Smith
Tags: Blogging Tips, Blog, Authors, Blogging, Writing

In the military, every few years there is a change of command. The current leader is replaced with a brand new leader. This change of command is typically accompanied by a long ceremony to mark the occasion where the entire audience, made up of the hundreds if not thousands of military members, bakes in the sun while the old commander gives a long-winded speech as their farewell and the new commander does the same but in the form of an introduction.

These high ranking men and women certainly deserve this time and attention, but that doesn’t take away from the fact that these are typically boring events that people are forced to sit through.

This was not the case for Captain Michael Abrashoff, Commander of the USS Benfold, during his farewell speech. He successfully turned around the worst ship in the Navy into the top performing ship through his leadership which he describes his book It’s Your Ship: Management Techniques from the Best Damn Ship in the Navy. If there was anyone deserving of everyone’s time and attention to give a lengthy farewell speech during the change of command ceremony, it was him.

However, he decided to do the exact opposite.

He realized he had already left his mark during his time on the USS Benfold. His farewell speech consisted of five words: “You know how I feel.”

I keep this in mind when I write conclusions for my books. I keep them short and to the point. One to two pages max. What more is there needed to be said?

The reader has already gotten through the real meat of the book. The conclusion is merely a napkin to wipe your mouth with and nothing more.

You may like a long conclusion and that’s perfectly fine.

For me, I like to accomplish the following in as few words as possible:

Congratulate them on making it to the end of the book. Not many people finish the books that they start.

2. Summarize a few highlights from the book in a sentence or two.

3. Give one last call to action whatever that may be.

That’s it!

Your assignment: draft your conclusion, say what you NEED to say (not necessarily everything you WANT to say), and call it done.

Comment on any questions you have below.

More to come. Stay Tuned.

Blogging is not a fashion motto. It is an essential business tactic. Customers and clients are not interested in your features, they are interested on what form are you beneficial to them.

HUBSPOT in their article says that “Marketers who concentrate on blogging are13 times more likely to expect a positive Return on Investment (ROI)”.

Steps to be a Better Digital Marketing Blogger:

1. To write blogs on digital marketing it is necessary to be updated with the same. Following a few Top most Digital Marketing Influencers is a start!

2. Word play makes the readers stay. You see what I did there, right? Exactly! Make your content interesting, but give extra sprinkle on your ice cream (aka: your content) with mindboggling headline.

3. The more you know about the SEO tools, the better you work on reaching your audience and driving traffic to your site.

4. Blogging is about your readers, not yourself as a blogger. Write about your target audience’s main interest. Back up your thoughts with data and images- it gives your readers a confidence to read further.

5. Stay, don’t stray. Over enthusiasm can cause a writer to stray from his/her topic. Please don’t give in to the temptation. Trust me! I know.

6. Comment interaction is a stepping stone for engaging more audience and drives traffic to your site. Read other blogs in your own niche, engage in their content which induces other readers to look for your site.

7. Lastly and most importantly, indulge in Social Media Marketing (SMM) for your own blog. Pictures speak a thousand words- use your technical editing skills on promoting your content in a minimalistic way in other social platforms.

Blogging Guide: Professional Advice To Help You Succeed With Blogging
By: Rohit Kumar
Tags: Blogging Advice, Blogging Tips, Blogging, Blogging For Business, Blogging Competition

Among the most well-known techniques to inform people about your own life is maintaining a weblog or blogging. Blogging may involve journal-like admissions about your lifetime, a topic you understand about, photographs or a mixture of all three. Keep reading to learn some excellent strategies to maintain your site participation to readers and possibly, make yourself a little cash.

Ensure you always post when conducting a site. If you do not post content frequently, then your website traffic will diminish relatively fast. Take a guest post or get info submitted, too, so your viewers can interact and supply feedback. In case your readers are pleased with your answer, they’re more inclined to return.

Produce a blogroll. Making such a list raises your site’s worth for readers since they might have the ability to find the content they could not locate on your blog. Should you use your site for promotion, a blogroll will also raise your credibility in the market.

After blogging, you need to ensure you create your RSS feed as straightforward as you can. You can’t expect different readers to locate it if it blends in with the text in your blog. That is why you need to set it in a prominent place on your site and attempt to create use of the orange RSS icon when possible.

You ought to be adding fresh content to your site daily. If you would like to maintain your website prominent with all the search engines, you should consistently post new entrances. Be sure that what you write is helpful, not only a great deal of fluff to state you made some entry.

3 Reasons Why Using Numbers in Your Headlines Works
Tags: Entrepreneurship, Blogging Tips, Blogging, Growth Marketing, Growth Hacking

Your blog article heading is the main hook to draw people in to read it, and it is up to you how well you can craft it. Take a look at the search results below.

Each of these headings contains the exact figures. This technique is so popular because of social interest. Consider these statements below,

“I’ll give you 10 apples for $5. “

“I’ll give you several apples for $5. “

Both statements are in your benefit, but the first one assures you and removes any doubt. “10 apples” is precisely what you will get.

Now from the articles below, which one are you more likely to read?

The first one assures you that you will know at least 3 Hacks by the end of this article. This is the power of adding exact figures to the article heading.

Here are 3 reasons why using numbers in your headlines generate more traffic:

1. SUBSTANCE: The promise of something specific.

2. STRUCTURE: Make reading easier.

3. CLEAR ORGANIZATION: Essential for speed reading.

Remember, a number is always better than a word as they are easy to digest.
Async-Await in Rust by Philipp Oppermann’s
By: George Shuklin
Tags: Async, Pin, Theory, Programming, Rust

Link

https://os.phil-opp.com/async-await/

Async-Await by Philipp Oppermann’s in his blog ‘Writing an OS in Rust’.

Description

In-depth description of async-await mechanism, covering both theoretical part, and practical part in Rust. It contains additional chapters on Pin (and why it’s needed in Rust), describes Futures , talks in details on advantages and disadvantages of async operations, and, finally, provides a concrete example for async/await been used for processing keystrokes.

Why?

Most articles I saw on topic are covering a very little of the whole topic, mostly focusing on details and lore around use of async. Some of them close to ‘make it work’ style, without providing rationale and limiting motivation to ‘it’s fast, dude’.

What I’ve learned

I got motivation to try async in Rust, I got a concise overview with a good practical introduction. But the main surprise was an excellent pass on Pin type. I saw it before in some code (rust for linux kernel, mostly), and I somewhat guessed what it does, but not the whole grandiose of Unpin auto-trait.

Second read?

Absolutely, yes. The text is really tight and closer to a book (or, at least, a pair of chapters from a book), and it requires time and practical experience to absorb it all.
Taking a Break
By: Raja Sekar
Tags: Rustlang, Programming, Rust

So I have finally decided to take a break from my professional life. Many around me questioned my whim of taking a break at this early stage in my career, since it’s been only two and half years, since I started working. Well, it’s kinda hard to explain. I am feeling little burnt out even though my work has been really interesting till now.

This briefly describes my life so far:

After studying hard in high school, I was able to secure a seat in one of the premier technical institutes of India. I slacked off a bit for the first two years of my college life. I was reading and learning stuff but without any focus. I had squandered a ton of hours on Greek and modern philosophy, on video games and so on. I was interested int math. So for the last two years of my college education, I indulged a bit on math and decided to pursue Masters in math. I also got sidetracked towards the MBA dream a little bit. One could easily notice the lack of focus here. A weakness of my trait was that I found (and still do) so many things interesting, I got lost in them without any goal or focus. I took up a job to save some money for higher studies. Life took a turn there. I had then started to develop an interest for Coding and Machine Learning while working on my job. Well the Buzz surrounding “Data Science” also helped a bit. I left my idea of pursuing masters. In fact I started to resent academics for some reason.

For compensating my unproductive college years, I learnt and worked a lot in the past one and half years. It was too productive and satisfying for me. I never knew that I could learn so many things in such a short time (simultaneously cursing the past me). I have done a lot of very interesting prototypes, some of which went to production and the rest sitting on my laptop without a ray of hope.

After this….

That productivity came at a cost. It’s been one year since I read any book other than technical books. I didn’t watch any good movies. Travelled a lot less than I would have loved to. I developed a keen interest in distributed systems theory and I almost never got time to work on that since it’s far off from my typical field. There were a bunch of other personal problems too. All of these finally pushed me to take a break. I don’t know how long it will last. Until I feel replenished mentally, I am planning to continue with this break. I am also contemplating to improve my writing skills in the meantime.

Well in the original author’s defense golang is more popular than these languages(all but c/c++, Java, and c# ofc). It all comes back to pragmatism, it’s worth learning because it’s used a lot. In my space I end up writing/reading a lot of go for things like kubernetes, docker, and all kinds of tools in that ecosystem, and that’s not something I can change even though it seems like a perfect use case for some other languages that come to mind(rust would be perfect in the container software ecosystem). I do agree that go isn’t really a great or fast language, but it’s tolerable and it’s popular. I do however love elixir, we use it at my work, and I prefer to spend my free time writing Rust because the language concept absolutely fascinates me and idiomatic Rust is incredibly powerful, useful, and productive. I can compile single files on the fly in seconds because rust has 2 intermediate languages, so the compiler can perform checks without a full compilation, and I believe soon(if it’s not already in nightly) you’ll be able to run tests without full compilation. Traits, are super powerful, and I just love how it’s created a bunch of libraries that are capable of working together even though they weren’t purposefully designed to because they implement dependent traits. Super cool stuff, there are some things I think are missing. It’s pretty much impossible to write purely functional rust that’s idiomatic, at least in my few attempts, and I’d really really love to see pattern matching call signatures like in elixir. I’m excited to see what’s to come in the future, super clever people contributing code and ideas, just go look at the GitHub issues page and see what’s coming down the pipe.
WASP, a Lisp dialect for performant, concise Web Assembly modules
By: Noah Altunian
Tags: Rustlang, Webassembly, Lisp, Rust

Have you heard about Web Assembly (WASM)? It’s a binary format standard and assembly-like execution environment used for speeding up web applications.

It’s cool. Very cool. And now enters WASP.

From the README on GitHub (https://github.com/wasplang/wasp)

WASP is ‘a LISP programming language for extremely performant and concise web assembly modules.’ That means that you can use WASP to generate WASM modules. Here’s an example:

; main.w

(extern console_log [message])

(defn main "main" []

(console_log "Hello World!"))

This will generate a WASM module that logs ‘Hello World!’ to the browser’s console.

The impact of WASP can be huge. Lisp is a family of languages; that means that there are many versions of Lisp without having an official implementation. Infact, Lisp’s main requirement is the idea of homoiconicity; that is, Lisp is represented primarily through code as a data structure. Take the above WASP example :

(console_log "Hello World!")

See those () 's? Everything inside of the parentheses is valid Lisp code, but the parentheses themselves define a data structure called a list. So Lisp is defined by defining lists, which are composed of other data structures, such as strings (such as in the above example).

In the end, Lisp programming allows for some flexible and interesting solutions to programming problems.

Lisp programming, although somewhat niche, boasts a large, dedicated following, and many other programmers tinker with Lisp as a form of right-of-passage or out of sheer curiosity. Because of this, WASP is bound to attract some attention, especially considering that Web Assembly is just now starting to really make some headlines.

Because of this premise, I think that WASP is very cool, and I am very eager to see further development. I want to give a shoutout to the developer behind WASP! Good luck on future endeavors.

In the end, I believe Web Assembly is bound to change the world. And you know what, WASP maybe can change the world too.
Rust Internals
By: Khalid Hourani
Tags: Toolchain, Programming, Llvm, Rust

Toolchain and Internals

A Rust toolchain is a single installation of the Rust compiler. These are managed through Rustup, a Rust multiplexer; it installs and manages all of these Rust toolchains through a single set of tools installed in ~/.cargo/bin . When rustc and cargo are called are proxies which delegate to the real toolchain, and Rustup allows one to easily change the active toolchain.

When rustup is first installed, it defaults to the official stable release. Running rustc will run the proxy in $HOME/.cargo/bin/rustc , which runs the stable compiler. If you change the default toolchain to beta with rustup default beta , then rustup will execute the beta compiler instead.

By default, Rustup will only track changes from the stable release. However, Rustup can be used to track changes from any release, such as beta and nightly, releases, as well as archived releases, releases for alternate platforms, and from local builds.

A standard release toolchain has the following structure:

<channel>[-<date>][-<host>]



<channel> = stable|beta|nightly|<version>

<date> = YYYY-MM-DD

<host> = <target-triple>

Rustup can be updated with rustup update . For more detailed information on Rustup, visit https://github.com/rust-lang/rustup.rs.

Intermediate Representations

Intermediate Representation in Rust

Currently, Rust comes with three levels of IRs (Intermediate Representation) and they are: HIR “high-level” IR, MIR “mid-level” IR, and LLVM “low-level” IR. MIR is a new recent addition Rust creators have developed that aids with optimization. To get a glimpse of the inner workings of Rust’s compiler let’s take some Rust code and follow its journey through the compiler.

Building a cargo project, we can trace the code’s path by starting off with showing the code after parsing. We can do this by asking rustc as follows:

Next step is expansion of macros and syntax extensions. The results can be seen with:

Here we see some libstd imports that were implicit in the source. HIR is a compiler friendly representation of the abstract syntax tree that is obtained after parsing, expanding macros and resolving names.

Now the code is ready for type checking. rustc infers a type for every expression, then checks that they all make sense together. You can see the inferred types with:

Only a snippet of the output was able to be captured but here we see what will be fed in the MIR type checking. This level of IR is useful for flow-sensitive safety checks (borrow checker), optimization and code generation.

Next, we can look at the LLVM code.

Rust’s performance wholly depends on LLVM. Here is where a majority of optimization takes place and is why Rust has great performance. In the LIR, or low-level intermediate representation, this LLVM bitcode is typically some SSA-representation of the Rust source code in some machine-like language.

Now that we’ve traveled through these three levels of Rust’s compiler, the computer is ready to interpret those instructions and run away.
Learning To Use Rust Over a 16-Hour Hackathon
By: Sid Shankar
Tags: Programming, Rust, Hackathons, Rustlang, Software Development

Getting Started on the Back End

A Google search for “Rust web framework” yielded a top hit for Rocket. I dove into the site to find the documentation and examples seem well laid out and thorough.

One caveat with Rocket is it needs the nightly version of Rust to operate. Not a big deal in th context of a hackathon.

The GitHub repo has plenty of examples. Perfect.

I used Cargo to set up a new project, added Rocket as a dependency in the TOML file, and following the instructions in the Getting Started guide for Rocket, set up a route:

#[get("/")]

fn index() -> &'static str {

"Hello, world!"

}



fn main() {

rocket::ignite().mount("/", routes![index]).launch();

}

For anyone familiar with Django, Flask, Express etc., this should look very readable. As a Rocket user, you use macros as decorators on functions to map a route to a handler function.

At compile time, the macros are expanded. This will be completely transparent to you. If you’re curious to look at the expanded code, the cargo-expand crate can be leveraged.

Here are the interesting/challenging highlights of my app-building experience with Rust:

Specifying the route response

I wanted my contents route to list all the files in the S3 bucket by returning a JSON data structure.

Notice (in the code below) how you can look at the function handler associated with the route to immediately determine the response shape.

Crafting the response shape was extremely easy. If you think of the JSON data as a structure with fields, where each of those fields could, in turn, contain its own structure and fields, then this maps well to a Rust struct .

So all you have to do is to define the struct (s) that constitute the response data shape and tag each one with:

#[derive(Serialize)]

struct (s) tagged with #[derive(Serialize)] can be passed to the JSON function from rocket_contrib::json::Json , and away we go!

Working with multipart uploads

I was knee-deep in building the application with Rocket when I realized I’d likely have a form on the front end that’d result in a POST with multipart/form-data .

Unfortunately, Rocket (as of v0.4) doesn’t have multipart support. This seems to be scheduled for v0.5.

This meant having to work with the multipart crate and needing to figure out integration with Rocket. The resulting code worked but could’ve been a lot cleaner with in-built multipart support in Rocket.

Configuring CORS

Once the routes were in place and I’d done some testing using curl and Postman, it was time to integrate with the front end. I needed to set the response headers appropriately to avoid CORS issues.

Again, there’s no in-built support in Rocket.

Looking through the issue log on the GitHub repo, I saw some of the building blocks for a solution, which resulted in this:

Shortly afterward, I discovered rocket_cors, which significantly slimmed things down.
Rust Basics: Structs, Methods, and Traits
By: Abhishek Gupta
Tags: Coding, Beginner, Programming, Rust, Tutorial

Methods

Methods are behavior associated with a given type. The first parameter in a method is always self , which represents the instance on which the method is being invoked.

Let’s add a method to Programmer . To do that, we will need use an impl block:

impl Programmer {

fn is_same_as(&self, other: Programmer) -> bool {

return self.email == other.email;

}

}

The is_same_as method accepts a reference to the instance being invoked on ( &self ) and another Programmer instance. To call it, create another instance of a Programmer ( pg2 ) and compare pg1 with it.

self types

We used &self as the parameter for is_same_as . This way, we will only pass a reference and the function will not own the value — only borrow it (see Rust: Ownership and Borrowing). It is also possible to use self and &mut self .

You can use self , but be careful that it will pass on the ownership to the function. Let's see this function.

You can invoke it using the pg2 instance as such pg2.details(); and you should get back:

If you try to use pg2 again (e.g. pg2.is_same_as(&pg1); ), you will get a compiler error:

error[E0382]: borrow of moved value: `pg2`

If you want to mutate the Programmer instance, make use of &mut self as follows:

If you don’t mark the variable ( pg3 ) as mut (mutable), you’ll get a compiler error:

error[E0596]: cannot borrow `pg2` as mutable, as it is not declared as mutable

Other functions related to a struct

You can add associated functions that are tied with the instance of a struct — think of it as a static method in Java. These are commonly used as constructors.

It’s different from how constructors are used in Java but similar to the Go approach.

Here is how you can use it:

let pg3 = Programmer::new(

String::from("abhirockzz@gmail.com"),

String::from("https://github.com/abhirockzz"),

String::from("https://medium.com/@abhishek1987"),

);

Notice that we are using :: ( Programmer::new ) to access associated members of a struct (a function in this case).
Rust: Ownership and Borrowing
By: Abhishek Gupta
Tags: Coding, Programming, Beginner, Rust, Rustlang

Ownership in Rust

Ownership = binding/association of value to a variable. The rules are:

Only one owner at a time.

If the binding is “released”, ownership is “gone” and data is “freed”.

let p1 = Person::new(); //1

p2 = p1; //2 let p1 = Person::new();

do_something(p1); //out of scope

On line 2, p1 will be freed. It's out of scope since it has transferred ownership to p2 . Passing p1 into another function also has the same effect.

let p1 = Person::new();

p2 = p1;

println!("person {#:?}", p2)

println!("person {#:?}", p1) //compile error

That’s the reason Rust does not allow you to use that value again. It enforces this at compile time using borrow checker.

Drop

It is possible to implement the drop method from the Drop trait if custom cleanup logic is required. It will be automatically called by Rust when that value goes out of scope

Once a variable is out-of-scope, i.e. its ownership has been relinquished, the Rust compiler will not allow you to use it again, since it needs to be “freed”. This is also called Moving , i.e. ownership of p1 moved to p2 .

Ownership is applicable to heap data only, not stack data since it (stack data) is “copied”, not “moved”.

Copy

The Copy trait allows a value to be copied. All the primitive types (e.g. i32 , bool , etc.) implement Copy implicitly.
Custom Implementation of Blockchain In Rust(Part 3)
By: Knoldus Inc.
Tags: Rust Programming Language, Rust, Cryptocurrency, Blockchain, Blockchain Development

In previous blogs(part-1 and part-2), we created a sample blockchain application. We also implemented validation and proof of work algorithm. Now we are going to upgrade our blockchain to simple cryptocurrency. We can do this by:-

Including the functionality of paying out rewards to miners

Signing the transaction

We will be covering only first part in this blog. We will cover transaction signature in next blog.

Paying Rewards to Miners:-

Anyone from anywhere can become a miner. Mining is a computer-intensive work where miners need to solve a puzzle called “Proof of Work”. Anyone who solves the puzzle first gets to add the block in the network and is rewarded for that.

We have to do few things:-

1) Add Mining reward

2) Store unmined transactions

3) A new function to mine a block for unmined transactions

Let’s start coding. Add a constant variable in the library file.

const MINING_REWARD: f32 = 100f32;

Now we will be adding two new properties in our blockchain class. One is for pending transactions and another one is for mining reward which will control how much coins miner get as reward.

pub struct Blockchain {

blocks: Vec<Block>,

unmined_transactions: Vec<Transaction>,

mining_reward: f32,

}

We will replace the add_block method with mine_unmined_transactions method. This method will not only mine a new block with all the pending transactions, but it will also send a mining reward to the miner. If you notice, mine_unmined_transactions method also takes miner_address as input. Once you successfully mined a block, the system will create a new transaction to give you your mining reward.

pub fn mine_unmined_transactions(&mut self, miner_address: String) {

let transactions = &self.unmined_transactions;

let mut block = Block::new(transactions.to_vec());

match self.blocks.last() {

Some(pre_block) => block.set_pre_hash(pre_block.hash.to_owned()),

None => block.set_pre_hash("0".to_string()), // genesis_block

}

block.set_hash();

block.mine();

self.blocks.push(block);

self.unmined_transactions = vec![Transaction {

sender: String::new(),

receiver: miner_address,

amount: self.mining_reward,

}];

}

Now, this method has the logic for:-

Create a block object

Set hash and pre_hash

Mining unmined transactions

Adding a block to the chain after mining

Create a new transaction for miner reward

In the mining method, we have included all unmined transactions in the block. But this is not the case in the real application. Because the size of a block is limited. In Bitcoin’s case, there is a block size limit of 2mb.

Why Rust Language Should Consider Tk For An Alternative GUI Library.
By: Robin Deatherage
Tags: JavaScript, Browsers, Rust, Rustlang, GUI

Of about six plus years of debate and countless considerations for a dependable GUI Framework. I wish to point out a number of advantages that Tk has over many other GUI Libraries.

First of all Rust is well known for it’s robust and very advanced language for Web Browser Technology, Web Assembly and the ability to handle CSS Attributes and JavaScript along with Threaded Processing support.

This being said, Tk is the only GUI Canvas Widget Set that has ever been used outside of the current in use highly customized NCSA Mosaic Canvas Widget Sets used by both Microsoft and WebView. Windows uses a customized version they obtained from Spyglass Inc. that used Mosaic as a pre Netscape version of the Berkeley Mosaic Browser and it’s Mosaic Engine.

Then WebView using its highly customized version of an upgraded Netscape Navigater version of the same NCSA Mosaic Widget Sets and Canvas being introduced as an API along with a Named Library access version likewise. All of which are used by Chromium, Chrome and Java’s own FxWebView.

Up until 2009 and as late as 2010 there existed over fifteen Browsers all written in various forms of Tk for web Browsers. One you may all know of is Mozilla FireFox’s first Ghecko Engine.

The problem today though is the scrutiny of the Tk library by many developers who clearly have not studied Tk’s abilities for such things as it’s Browser GUI Rendering Engine capabilities.

Many articles bad mouth Tk as an out of date GUI Library but are seriously misrepresented and unfounded for one. And Tk is at version 8.6.9 and is a adequately stable and complex library being updated in build cycles daily also.

As for it’s strength’s above Wx, Qt, Win, among many others is not only it’s ability to mimic them or run on “All Platforms” but also it’s ability to develop HTML rendering engine cells that have the ability to config after render pre loaded (or as it is termed as) setting Pre loaded Rendering Triggers for CSS and or JavaScript successfully.

I may be out on a Limb here, but honestly if the Rust Team keeps fiddling with debates on which course to take for a GUI Widget Library, then why not set Tk for a while as a Cargo add on to offer it as an alternative until something solid comes along.

This way some of us can keep going where Python has failed us in respects to Browser Engine Development and as an alternative GUI for software development. And of which the Mosaic Canvas remains Proprietary Non Open Sourced Software.

Tk is also entirely structured for many computer languages as a String Only Library tie in, it is very fast and is extremely advanced and complex enough for both Browser development and for Rust to expand with. Something Rust can clearly handle by my study and familiarization with presently.

An asset is a cryptocurrency tradable on the Porta blockchain.

A frequent question we normally get is “Can I create my own cryptocurrency on the Porta blockchain?”

Yes, and this tutorial shows you how!

Requirement: To create a new token, your Porta account must hold 12,500+ Porta tokens. It does not cost 12,500 tokens to create an asset, it is simply a holding requirement at the time of asset creation.

4. How to mint your own tokens

Minting essentially means generating tokens in your native cryptocurrency.

In this tutorial, we will show you how to generate tokens in your native cryptocurrency and send them to other addresses.

5. How to create a smart contract and load it onto Porta’s blockchain

Smart contracts are programs stored on a blockchain that run when predetermined conditions are met. This tutorial shows you how to do so on Porta.

Requirement: You have completed the installation, use this checklist found here to ensure you have done so.

6. How to interact with your smart contract

This shows you how to execute the functions of your smart contract.

Go to PolkadotJS Apps, found here.

Requirement: You will have deployed your smart contract to the Porta blockchain.

7. How to setup a validator node

This tutorial is designed to familiarise developers with the process of running a node on their local machine.

You will create the required accounts:

Create a stash account

Create a controller account

Create a reward account

Bond the stash and controller together; direct rewards to reward account.

The tutorial assumes the user already has Rust installed on the machine they will use for validating. However, if you do not, please refer to the following installation guide.

8. Setup a validator node on Digital Ocean

Using the skills learned in the last tutorial, we expand upon this model by running the server in a cloud VPS (Digital Ocean).

Robert Marshall recently joined the team as Rust Developer to contribute towards the development of the Porta blockchain. Robert brings a wealth of development experience to the company

Take it away Robert!

Introduce yourself?

My name is Robert Marshall and I am a Certified IT Operations Specialist with 9 years of experience as an Infrastructure Engineer. I have a keen interest in IT Security and professional development experience with Rust, Python, Java and VBA.

Prior to a career in IT, I spent 13 years in psychology understanding how thought functions. I am a published author of philosophy who has proposed a new therapy model.

All-round Crypto enthusiast and humanitarian.

What is your role at Porta?

I work as a Rust Developer theorising new technologies and implementing them through the creation of custom pallets and smart contracts using Parity’s Substrate framework and Ink libraries.

Why Porta?

The Substrate framework Porta uses is a powerful technology that gives us the freedom to customise our ecosystem when we need to and the freedom to focus on developing business logic when we want to. The framework allows us to imagine products and bring them to market very quickly.

The staff at Porta are all kind, hard-working, smart people who are energetic and passionate about their own development, the development of the company and the development of the crypto industry as a whole.

Porta gives its staff the freedom to invent and build the future.

We believe in what crypto can offer to the masses and we intend to make that transition as easy, appealing and feature-rich as possible.

What’s next?

I am passionate to further my knowledge of Rust, the Substrate framework and the Crypto industry. While helping users enter the crypto world, I would also like to help onboard developers into the substrate ecosystem.

At some point, I would be interested to bridge my understanding of psychology with technology to create a powerful Artificial Intelligence.

As a company, we will continue to develop quality products and grow partnerships with innovative companies and individuals to create a better world for us all to live in.
