Is There a Cryptocurrency Bubble? Just Ask Doge. - NYTimes.com
Imagine that a friend is building a casino and asks you to invest. In exchange, you get chips that can be used at the casino’s tables once it’s finished. Now imagine that the value of the chips isn’t fixed, and will instead fluctuate depending on the popularity of the casino, the number of other gamblers and the regulatory environment for casinos. Oh, and instead of a friend, imagine it’s a stranger on the internet who might be using a fake name, who might not actually know how to build a casino, and whom you probably can’t sue for fraud if he steals your money and uses it to buy a Porsche instead. That’s an I.C.O.

The Hard Thing About Software Development | Jesse Watson | Pulse | LinkedIn
"The most valuable asset in the software industry is the synthesis of programming skill and deep context in the business problem domain, in one skull."

"...there are an ever decreasing number of software problems that are so cut and dried that they can be tossed over a wall and implemented in isolation of business expertise."

Applying the Universal Scalability Law to organisations | the morning paper
"
1. It’s really important you learn to delegate effectively and to choose carefully the things that you do get involved in.
2. As the organisation grows, strive to keep the number of stakeholders that need to be involved in any decision down to a minimum
3. You need to keep a strict handle on how many things you’re involved in concurrently; your natural human instinct to be helpful to everyone who asks you to do something for them, or to contribute to their project, actually isn’t helpful at all. (Nor is your desire to control / influence everything if you’re wired that way).

[JOB] Ruby/Postgres Developer in Melbourne, 4 Month Contract
For metrics and reporting, we have an internal data warehouse that
sits behind a JSON API. It works brilliantly, but with the volume of
data we have these days it's showing it's age. The core events table
is up to 60 million rows and growing at ~5 million rows per month.

Some API calls are slowing down, some need new filtering options, and
we need to expose some new aggregate data. We're also wondering, what
happens when we hit 150 million events? 200 million?

Abstractivate: Hyperproductive development
Let's talk about why some developers, in some situations, are ten times more productive than others.

When do we get that exhilarating feeling of hyperproductivity, when new features flow out of our fingertips? It happens when we know our tools like the back of our hands, and more crucially, when we know the systems we are changing. Know them intimately, like I know the contents of my backpack, when I packed it and I tuned the items in each pouch over years of travel. Know the contents of every module, both what they are and what we'd like them to be if we ever finish that refactoring
