Building a crypto-currency POS with an API.

Bitcoin Featureed Image

I’ve recently been working on a project to create a crypto-currency wallet and API for POS transactions. I won’t tell you which crypto-currency I’m working on publicly, but if you want to hire me for helping you to create a POS system, blockchain parser, or API. Please let me know. First off, I had to choose between two packages: Node.js driven bitcoin-insight-api, and python scripted bitcoin-abe. Both are available on GitHub. https://github.com/bitcoin-abe/bitcoin-abe https://github.com/bitpay/insight-api Although it seems that node.js is increasing in popularity everyday, and python is looked down on by some for it’s high-level syntax, I eventually decided to use bitcoin-abe for the time being with hopes of eventually modifying the insight app. My reasoning is as follows: insight is dependant on bitcore.js. Right now there is not much documentation out there on modifying bitcore to work with alt-coins. There docmentation even advises that the package is still in development…

Although I’m new to security encryption techniques and do not have worlds of experience or experience under my belt, I’m constantly learning more. I’m also a regular listener of the podcast Security Now with Steve Gibson on the TWIT network. Last week, the podcast was Steve’s presentation of SQRL (pronounced “squirrel”), which attempts to solve security, privacy and usabilt issues regarding the age old computing paradigm of username / password account security. To a large degree it seems that Steve’s proposal takes from the SSH paradigm used for secure logging into remote servers; namely an asymetrical key pair. Not only does this allow the user to avoid remembering a laundry-list of usernames and passwords that need to be periodically changed for optimal security, but also improves user privacy by allowing some information about the user such as email address to be excluded from the requirements for a user account. Understandably,…

Nodejs – Becoming a more important web-app package everyday

I’m now learning Nodejs. Here are some links to articles and tutorials on how to get started in nodejs. Express for nodejs tutorial This is a great tutirial for getting started with nodejs. It shows how to create a package.json file and install using npm from there. This is important as a fast, reliable, and reproducable way to get the nodejs packages you need all in one place. The tutorial continues to show how to set up nodejs to listen on localhost port and also how to set up a basic router and directory / file structure. http://codeforgeek.com/2014/06/express-nodejs-tutorial/ http://codeforgeek.com/2014/10/express-complete-tutorial-part-1/ Nodejs and PHP Good article on using nodejs with PHP. I love php and it’s great they are compatible. That allows me to only apply nodejs for scripting some APIs (for example Bitcoin) and still use PHP as my main engine for serving dynamic website content. http://strongloop.com/strongblog/node-js-php-get-started/

Red Monk identifies hottest programming languages using GitHub

The most important programming languages is a concern. If you want to identify trends in web-app programming, web-stack, or even mobile, back-end etc., you need to forecast changes. This can allow you to make intelligent changes in selecting which language to apply to your projects. Here in January 2014 Red Monk uses GitHub repos to identify the most important languages out there right now. I’m sorry I didn’t see this until 2014 is almost over, however I believe it’s still relevant in 2015. Here is a quote from the Red Monk article itself: <quote>" While the appetite for up to date numbers is strong, the truth is that historically changes from snapshot to snapshot have been minimal. This is in part the justification for the shift from quarterly to bi-annual rankings. Although we snapshot the data approximately monthly, there is little perceived benefit to cranking out essentially the same numbers…
