Incremental programming is the process of writing code one step at a time and checking the output after each one. It’s common practice for data exploration workflows, and it goes a little something like this:

You’re using pandas to do some Python data analysis. The first thing you do with your new data set is print df.head() to get a sense of what the data looks like. You notice there are a few NaN values in the first five rows, so you print to see how prevalent they are throughout the data set. …

The Ethereum developer community uses the ERC20 and ERC721 token standards to create digital assets on the blockchain. These token standards define how users are able to transfer ownership of compliant digital assets. And because the standards are so widely adopted, we have witnessed the creation of powerful tools that are able to service these tokens. The common interface for transferring ownership of these digital assets is powerful. However, the inclusion of a few optional pieces of data has proven useful as well, namely, token name, symbol, and the number of decimals. …

“How many people here are working for or planning on starting their own Blockchain-focused company?”

When speaker Michael del Castillo of Coindesk posed that question at the inaugural Penn Blockchain Conference, more than half of the attendees’ hands shot up. This excitement in the Penn and Philadelphia communities stems from the wide array of applications for blockchain technology. Many of the most exciting ones were discussed during the “Disrupting Finance” panel of the Penn Blockchain Conference.

The panel members include:

  • Andrew Keys (Co-Founder of Consensys Capital)
  • Brian Steele (Managing Director at Goldman)
  • Griffin Anderson (Founder of Balanc3@ConsenSys)
  • Danny Aranda (Managing Director at Ripple)
  • Jitin Jain (Wharton MBA ’18) (moderator)

If you have heard about Ethereum, then you have probably also heard about “smart contracts.” Without getting too much into the technical details, let’s look at why they are interesting.

Let’s start with a simple example. Suppose three friends, Alice, Bob, and Mike, are starting a business. They create a bank account for their business and each deposit their own money into the business’ account. Because they are all founders of the business, they all have access over that account. Suppose, after creative differences, Bob wants to start his own company. …
