Google Going Crypto

Posted on January 20, 2022 by Edward Fitz

As the firm looks to provide a wider range of financial services, including cryptocurrencies, Google has hired veteran PayPal CEO Arnold Goldberg to manage its payments division.

Google’s action comes after years of debating whether or not to invest directly in the embryonic blockchain technology. Twitter’s investment in crypto infrastructure, as well as Facebook’s efforts into the metaverse, look to be catching up to the internet giant.

Also Google hired a new “Founding Leader” for blockchain project, Venkataraman.

According to his LinkedIn page, Venkataraman, who has worked for Google for more than 18 years, brings more than 25 years of experience as a software engineer with firms such as IBM, as well as more than 10 years in paid advertising for the internet giant, to the table.

Top 3 DNS Providers That Provides Good Service in SEA (Southeast Asia)

Posted on August 20, 2019 by Edward Fitz

If you give a hacker a new toy, the first thing he’ll do is take it apart to figure out how it works.

— Jamie Zawinski.

DNS or Domain Name System sometimes called the phonebook of the internet is one way for us to easily access our favorite website, it translates and redirect human readable domain names (e.g. yahoo.com, google.com) to their respective IP address. Finding the good DNS provider is vital in accessing information that is sometimes censored by our government, ISP and the likes. This are my top three good DNS (Domain Name System) providers that are really fast, secure and reliable that can be use in Southeast Asia.

Cloudflare

Cloudflare Public DNS (IPv4)

1.1.1.1
1.0.0.1

Cloudflare Public DNS (IPv6)

2606:4700:4700::1111
2606:4700:4700::1001

So why Cloudflare¹? Choose Cloudflare if you want less than <1ms of domain name resolution. Seriously, they have the fastest name resolution on the internet.

Google

Google Public DNS (IPv4)

8.8.8.8
8.8.4.4

Google Public DNS (IPv6)

2001:4860:4860::8888
2001:4860:4860::8844

So why Google²? You will use this if you need an old but still good reliable DNS server. Its been used as a primary name resolution on big companies as well as local workstation. Its much more better than your ISP (Internet Service Provider) provided DNS.

Yandex

Yandex DNS (IPv4)

77.88.8.8
77.88.8.1

Yandex DNS (IPv6)

2a02:6b8::feed:0ff
2a02:6b8:0:1::feed:0ff

So why Yandex³? You’ll choose this if you’re a webmaster due to super fast name resolution propagation. This is the fastest DNS for name resolution propagation, on which ever region you are currently.

These three are mostly corporate but they do provide fast speed TLD name resolution. And if you really still feel they can be manipulated, feel free to enable DNSSEC. For example on CloudFlare, a single domain would resolve at less than <1ms.

So guys, what are your top DNS providers?

Flutter Series – Creating Your First Hello World

Posted on November 22, 2018 by Edward Fitz

When you can’t find the sunshine, be the sunshine!

— Anonymous.

Have you ever dream of building your own app, but think its too hard. Why don’t you try flutter…

Flutter is a new way to build multi-platform app which is currently backed and develop by Google. Its often compared to react native, but the difference is performance. React Native runs on JavaScript bridge while Flutter on dart bridge. What dart bridge does best is AOT (ahead of time) compiling to native ARM code.

Prerequisites

First of all you need flutter, just follow the steps below in order to run install it.

Flutter 1.0

Building Hello World

First we will install flutter, depending on your operating system you could find the details on how to install flutter here. On arch Linux you could find it on AUR repository.

After installing the flutter package. Run flutter doctor to check for any dependency error.

And now we begin, to start a flutter project you need to type in flutter create <project-name>. For example I’m building a hello world project named stocks.

flutter create stocks

The command will create a directory named stocks which contains minimal running app template. What we do first is open the file lib/main.dart using your favorite text editor and rename the app title Flutter Demo to Hello World. Then remove the whole Scaffold block as we will create our own scaffold. After the changes your _MyHomePageState class would look like this.

// ....
class _MyHomePageState extends State<MyHomePage> {
	int _counter = 0;
	
	void _incrementCounter() {
		setState(() {
			_counter++;
		});
	}

	@override
	Widget build(BuildContext context) {
		return Scaffold();
	}
}
// ....

Clean up the unused functions and variable like _counter and _incrementCounter. If your editor has integrated linter and dart analyzer it would complain regarding unused variable. Once cleanup’s done, implement now a centered hello world text by adding body to the scaffold.

class _MyHomePageState extends State<MyHomePage> {
	@override
	Widget build(BuildContext context) {
		return Scaffold(
			body: Center(
				child: Text('Hello World!'),
			),
		);
	}
}

Now run your code using the command flutter run. If a device’s connected it will show an app displaying a centered hello world. You could also use an emulator by running flutter launch before running flutter run.

So what’s next?

Now after everything’s done, we will continue building our stocks monitor app on the next chapter. Stay tuned. Hit like if you like, subs if you love and as always live life.
