Blog: P2P

-

P2P is a way of communicating directly between two parties with no third parties in between. For example, normally if John wants to send a message to Maria over the internet, the message leaves his device and pushed to a server then the server sends a message to Maria device. Using P2P (peer-to-peer) commutation the message goes straight from John’s device to Maria device, just like a conversation in real life. Once the connection is established between two devices, each devices works as its own server and receiver allowing messages to travel uninterrupted. The first well-known use of P2P was Napster allowed you to make files on your computer available for other users to directly download. This is significant because it allowed each person to be a digital library for sharing. Since then bitcoin was created and gave new life to P2P systems. Bitcoin is a decentralized digital currency without a central bank that can be sent from user to user on the P2P network just like cash in real life.

    Hi Nisa,

    I agree with your comments on Bitcoin. Originally it was designed as a way to have a completely private way to spend money. Users could only be identified with long algorithmic hashes as usernames and unless people actually posted that information, it would be impossible to know who it belonged to. On the internet I read a few stories on how crazy and unregulated the market got. In the early days, someone purchased pizza for 10,000 bit coin which would be worth about $80,000,000. That would be the worlds most expensive pizza by an astronomical amount. In reality, I don't know if the market would ever be fluid enough to see a single transaction of $80 million not change the value, but its interesting still.

How to create bitmoji? To create your own bitmoji character, you’ll need to download the bitmoji app (you can download it for free from the App Sore on IOS or the google play store for Android.) Once you’ve downloaded it, open the app. You can sign in with your snapshot account if you have one or tap sign up with an email. Now it’s time to create your avatar, to make it easier to make your avatar look like you, you can snap a quick selfie for side-by-side comparison. Center you face in the circle, then tap the camera icon below to take a picture, now in creating your avatar you’ll see your selfie on the left.

Now it's time to work on your bitmoji face starting with eye, once you decided on an eye shape you can add eye color, eyelashes, change the size of th...

Blog: Wiki so Far

-
So far, I have edited retail wiki; formatting tables of context, changing the title, deleting extra images, fixing the grammars, and editing layout. First I checked the history to see when the last change was made, and which was 8 May 2019. The page context was off besides still needing a lot of work on editing. I change the title from “Retail and New Media” to “New Media in Retail”, moved the layout, started with talking about e-commerce business to local online retailing and deleted extra images.
