Medicine and health care are big business, particularly in the United States. In fact, US consumers spend over 1.5 trillion dollars1 on healthcare related expenses each year. Over the last few years, more and more apps have become available that help you monitor and improve your health. As they say, there’s an app for that.
In growing companies, as software systems become complex and extensively engineered, maintenance can be a challenging problem. Moreover, when high profile bugs arise and/or a lack of system availability arises, it can have disruptive consequences on a business. Hence there is little room for mistakes in these crucial systems.
At some companies, designers and developers have little to no interaction with clients or customers. It’s not uncommon for the people working on a project to be walled off from clients by account managers or customer service. At Grio, every designer and developer is client facing, and everyone ends up doing some of the work that is traditionally done by an account manager, such as managing day to day contacts, relationship management, and responding to problems & issues.
Howdy, lazy bum! Enjoying the ReactiveX magic? Want to take a look at polling?
I’ll be walking you through a solution I put together for one of our up and coming apps! It works rather well, I learned a lot, and so far no complaints…although there are no users yet either!
Feeling quite charitable, I’m going to let you in on some useful bits and pieces as we build up to polling: threading, late subscribing, replay, manual re-triggering and error handling (a must for preserving replays).
What is benchmarking?
Benchmarking is the process of measuring performance for a piece of technology against other pieces of technology. Typically, processors are benchmarked by running programs and software that heavily taxes the system. This allows the processor to truly shine (or, possibly, the opposite). For the purposes of this post, the i5 and i7 processors’ performance were measured in five different categories, each using one test:
You may have seen them on college dorm room walls or on your plate of cauliflower… you may know them when you see them, but what are fractals, really?
The Relational Model & SQL
The relational model was proposed in a paper published in 1970 by Edgar Codd, a computer scientist working at IBM. In previous years, some storage systems had already emerged, but the relational model was first proposed with a strong theoretical basis.
Scalability is a hot topic, especially in Content Delivery Networks (CDN) where scalability, robustness and availability are crucial. A CDN is a system that has the aim to deliver Web content, such as videos, images, and any other type, to end users. Content providers such as media companies need to deliver their content with high availability and high performance, and CDNs offer them the infrastructure to do it. There are different approaches, each one with its advantages and flaws.
Modern cryptography is a very murky subject for many people, so today I will try to explain to you one of the more complex subjects, Elliptic Curves. Many of you may have heard their name before, but likely don’t know much about them beyond that. To begin, I will describe what an elliptic curve is.
