Thoughts on the use of A.I

I love and support the use of AI or AI powered tools to accomplishing certain tasks that you would normally take hours or days or so. However, more and more big companies like Facebook, Twitter, Google, or social media companies are starting to take advantage of it by controlling the information on what to show and what not to show their users, altering the narratives, supervising the narratives, which is based on the individual’s or group’s decision that will have huge impact on a lot of areas like getting the right information, freedom of speech or freedom of writing and communication in near future.

Increasing the low quality resolution images wasn’t ideal to do in any kind of photo editing softwares under any circumstances.

Setup your own VPN server with Outline in less than 10 minutes

If you’ve stumbled upon this post via Google or search engine, I’m hoping that you’re already familiar with using VPN and you’ve already expected to see how to guide to setup your own VPN. If you’re not familiar with the term VPN below is the tl;dr for you to understand what VPN is.

TL;DR: Virtual Private Network (VPN) allows you to connect to the network which residing in different part of where you’re currently living. For example: if you’re living in Singapore and the VPN server that you’re connected to is in United States, the website or the app you’re accessing only to understand that you’re United States like you can browse some movies in Netflix which are only available in United States. VPN is not just about the location but it is also securing your data between your browser/app and the server you’re communicating. If you’re living in the country where some sites are blocked, you can use VPN to access those sites without being blocked.

Outline VPN

Outline VPN

Outline VPN is an open-source project created by Jigsaw that provides a safer way for individuals and organizations to access the open internet. What makes Outline VPN standout is that it lets you create, run, and share the access keys to your own VPN server with you don’t have to have much technical knowledge or going through all the complicated scripts to setup.

How to setup Outline VPN

This guide will walk you through how to setup your own Outline VPN server and create access keys to your devices such as computer, desktop, laptops , and mobile devices.

Sign up required at VPS providers

Outline VPN requires you to have your own virtual private server (VPS) which you can easily create an account at Digital Ocean, Amazon, Google Cloud Service, or Linode. I suggest you to use Digital Ocean which they offers $5 / month to run your own VPS server. Once you’ve finished setting up and provided necessary information like credit cards there, then you can follow the following steps.

Download Outline VPN Manager

Now, just head over to Outline website and download the Outline VPN manager for your operating system. If you’re using windows or mac, select the appropriate one.

Download Outline Manager

Install and run Outline Manager

After downloading the outline manager file for your operating system, please install and run Outline manager. Outline manager will probably look like this at the time of I am writing.

Outline Manager running on Ubuntu

As you can see the screenshot above, I’ve already setup two outline servers from different cloud providers.

Select VPS Provider

Now click “ADD SERVER” from the left menu and Outline will show you which provider you would like to setup. You can select Digital Ocean if you’ve created the account there. Press “CREATE SERVER”.

Cloud Provider selection in Outline VPN Manager

Select Location

It is important to know that you should decide which location you want to create your own VPS server to run outline VPN. For example: if you want to watch Netflix videos content available in U.S, you can select the New York or San Francisco. Once Outline has created the server, you can’t change it back. What you can also do is either you create a new VPS server in another region to install Outline VPS or destroy the existing one and create the new one again. It’s all up to your decision.

Location selection in Outline VPN Manager

Give authorization access at Digital Ocean

Next step, Outline Manager will open the browser and you have to give authorization access at Digital Ocean in order for Outline Manager to create the VPS server and install Outline VPN server on behalf of you. It may take about two minutes depending on the connection.

Create Key Access for your Outline VPN clients

You’ll see something similar like the screen below after the setup has been completed. All you have to do is to create the keys for your devices. “Acess keys” allow you to connect with your device and your Outline VPN. Click “Add new key” and it will automatically create the key for you. You can click on the name to provide the meaningful name so that you can easily remember.

Free up memory in OSX Mavericks

Screen Shot 2014-03-05 at 11.23.16 PM

Lately I’ve noticed  that Mavericks OSX is consuming almost 8GB of memory which I have no idea why it used too much when I don’t have much app running. In order to free up the memory in OSX, you can try by typing



sudo purge

in terminal in which OS X will free up the “inactive” memory.

How to show hidden files in Mac Finder

This is the missing little feature in Mac that Apple doesn’t want to add it? In Windows, you can just check the show hidden files and folders in File and Folder options. In order to see hidden files and folders in Finder, open the Terminal from Applications->Utilities->Terminal. Type the following command line.

defaults write AppleShowAllFiles YES


To hide the files and folders back, just set it to NO. I hope this help.

defaults write AppleShowAllFiles NO

Keep it simple. Stay focused and keep shipping

It’s been more than a year I didn’t write or I don’t look back my blog. It was stupid to leave the blog that gave me extra income. I think it is time to organize my time to write a new post every week.
