Pure: ridiculously simple CSS modules

Pure: ridiculously simple CSS modules

Yes. Pure is a set of small, responsive CSS modules that you can use in every web project. Together or independently, pure CSS modules that enable you to put layouts in place and styling for native HTML elements, including the most common UI components. Zero Javascript: just CSS and at only 5.7Kb. If you just need the modules individually, you can only call the ones that you need, and since it is just simple CSS code, you can easily override or extend any part of it in your pages. read...

Audio visualization in HTML 5

Audio visualization in HTML 5

I love seeing new approaches and mashups of different technologies and when my friend Sann-Remy posted this fascinating experiment, I had to re-post it. He is using Web Audio API together with WebGL and making it work with three.js, a sophisticated 3D library for rendering objects in space on an HTML 5 canvas or WebGL. I don’t have much more to say than that I am very inspired by his work and that it raises the bar for my next experiment… ok Sann-Remy, it’s on! 🙂 See the experiment (use Google Chrome to see it and make sure to wait for the sound to load): read...

Chrome Extension code inspection

Chrome Extension code inspection

I was about to install an extension for Chrome and it was asking me for some permissions that I wasn’t ready to give up. I am sure it was ok, but I wanted to take a closer look, just in case. So, I know that Chrome extensions are just Javascript and some other files, right? I’d like to have a look. Where do I look, where are these files? You’ll find them here: The exact path is: clock.js C:\Users\<User>\AppData\Local\Google\Chrome\User Data\<User or Default>\Extensions\ Now, you need to find the Extension ID to find out which folder you need to look into. You find that here: Click on Chrome Settings here: When the menu opens, follow Tools > Extensions That will open the Extensions page. Here, look for your extension and lookup the ID. Find the folder with that ID and open it up and inspect the files. That’s...

Explaining Bitcoin to my 9 year old

Explaining Bitcoin to my 9 year old

I decided I wanted to create an address for my son and store 1 Bitcoin in it and give it to him. This way, he could be part of this new technology, way before it was mainstream and watch the value of his single coin grow or shrink. So, inevitably, when I told him I had given him one Bitcoin, the questions began: A bitwhat? What’s a Bit… oin? Well, first, it’s Bitcoin… B-i-t-c-o-i-n. Bitcoin is money, but instead of it being a coin, like you know it, it is computer money. You know how email isn’t paper and is really computer mail..? An email is a message that is inside the computer and when you send it, the recipient can read it from their computer. The same with Bitcoin. The money is inside the computer and when you send it to someone that person then has the money in their computer and can use it to buy things online. Can I see it? Where is it? It’s computer...

Bitcoin address collision

Bitcoin address collision

A Bitcoin collision is when two different people in the world randomly generate the same Bitcoin address. They would both have access to any funds in that address. Is that even possible? The answer: yes However, the chances of that happening are pretty much nil. Read on. A Bitcoin address consists of mainly two parts: an address (public key) and the key (private key) to that address. The address is the container for the funds and the key, well, opens the container. How this works, is that when you generate a new Bitcoin address, you are really generating a key pair. That is a private key is created first and the corresponding address is then mathematically computed and derived from that private key, so that there can only be one address for each key. Now, Bitcoin keys and corresponding addresses can be generated at will. Yes, you can create as many as you want. 100, 1000, 100.000? Go ahead, you can. In fact, when you create a wallet on...

Create a Bitcoin paper wallet

Create a Bitcoin paper wallet

A paper wallet is nothing more than the information of a Bitcoin key pair, printed on a piece of paper. This key pair, contains the address of where the funds are stored and the private key is the key to send or withdraw those funds. In other words, it is a pre-signed check with bitcoins. A paper wallet might look like this: The reason we want this on paper, is because, ultimately, having this on paper and away from any digital access is the best place to have the key to your funds. Away from your PC. Anywhere else, your data could be compromised by spyware or key loggers. There are many ways of doing this and everyone seems to have an opinion and a better way of doing this. Many will argue that you have to generate the key-pair on a computer that is air-gapped, or, in other words, is completely disconnected and has never been connected to the Internet, in order to avoid any possible mal-ware intercepting...

Why Bitcoin?

Why Bitcoin?

Bitcoin has been all over the news and many opinions have been posted and shared. Good news, positive opinions, bad news, negative opinions and everything in between. Just a year ago, the currency could be bought for just a few dollars. Just last month it was around $76 and jumped $12, to $90 in one single day. Two weeks later it was at $250 and then a hard crash to $60. Since becoming somewhat of a celebrity overnight, there has been quite a bit of demand and speculation about this new currency. Media sensation and  speculation made many people try to get a piece of the fortune to be made with Bitcoin. Many profited and many lost a small fortune by betting on Bitcoin. So, now that the bubble has burst and the dust has settled, the question remains: should you buy bitcoins? You’ll need to ask yourself what it means to you, since buying bitcoins means different things to different people. Here are a few reason why people...
