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.
As part of my exploration of a minimum set of devops tools, I’ve been learning how to stack containers full of Rails apps onto the Docker. There are plenty of examples of how to get started with Rails and Postgres on Docker, even one from the whale’s mouth, as it were. Working from this example, it was pretty clear to me that one of Docker’s major strengths is that it makes it really, really easy to get something running with a minimum of fuss; it took all of about a half day to learn enough Docker to hoist anchor, and even tweak a few things to my liking. One thing kept nagging me about the Docker example, though, and that was a warning from bundler when running docker-compose.
One of the great things about Grio is that designers and developers often work together on projects. We have lunch together and tell each other jokes while collaborating to solve challenging problems brought to us by our clients. Some projects come with constraints that force the team to be savvy in the way we produce deliverables. As a result, sketches and sketched wireframes are often a suggested deliverable.
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.
