The Design Mindset (2)
In a comment from last week’s post on the design mindset, which focuses on asking what through observation, Alan asked why I don’t focus on business drivers, or intent, first. This is a great question. Let me give you three answers before we actually move on to asking why?
Why can yuor barin raed tihs? Because your mind has a natural ability to recognize patterns and “unscramble” them. In reality, what you’re doing is seeing something that looks similar to what you’ve seen before, inferring that’s what is meant now, and putting the two together in a way you can understand. It’s pattern recognition at it’s finest—you’re already a master at this, even if you think you’re not. This is an important skill for assessing the world and reacting in (near) real time; if we didn’t have this skill, we wouldn’t be able to tolerate the information inflow we actually receive on a daily basis.
The danger is, of course, that you’re going to see a pattern you think you recognize and skip to the next thing to look at without realizing that you’ve mismatched the pattern. These pattern mismatches can be dangerous in the real world—like the time I Continue reading
OED tools: tmux
The need If you work with Linux machines and you don’t use a terminal multiplexer you’re doing it wrong. What is a terminal multiplexer? It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal. The Solution I use tmux, […]Picking Up the Baton
I’m incredibly excited and honored to take on the role of CEO of Cumulus Networks. In many ways, I’ve trained for this role my whole life. I grew up in Silicon Valley. I have had a front row seat to the growth of the tech economy and been fortunate to watch many passionate leaders grow companies from simple concepts to multi-million dollar firms. I couldn’t be more committed than I am today to bringing a lifetime of experience and learning to bear in leading Cumulus Networks to its next phase.
First and foremost, thank you, JR, for entrusting me with this enormous responsibility. JR and Nolan have both invested their hearts, souls and many years of their lives in Cumulus Networks. They have hired incredible people, built great products, signed impactful partnerships and — in a brief few years — have already had a profound impact on this industry. They have fundamentally changed how networking products are bought, sold, developed and deployed, and in the process spawned a legion of imitators. I’m honored to be entrusted with the job of moving this organization forward. JR and I bring incredibly complementary skills to the table; he is a technical visionary and Continue reading
Finding Level
Nolan and I started Cumulus Networks with a specific vision: to help people build better, faster, easier networks. To change the way that people think about building and deploying applications, regardless of scale. A lot of people have contributed into turning this vision into reality, and we’re excited by everything that we’ve achieved.
As we closed our series A, it was time to name a CEO, and we didn’t want to trust the company to a “professional CEO”. To that end, I took on the responsibility. In the early days I was able to stay involved with the technology and products; however, as the company has progressed, I’ve had less time to spend in the areas that motivated me to start the company.
Then along came Josh. He participated in our extensive (some would say exhaustive) VP of Sales selection process and stood out. His ability to grasp the business details as well as manage the team dynamics showed us that he has chops. He joined us in June of 2015 and continued to impress. He did his day job effectively by restructuring our sales team, refining the sales process, getting operations tight, and closing deals. He also became a Continue reading
To Compress or Not to Compress, that was Uber’s Question
Uber faced a challenge. They store a lot of trip data. A trip is represented as a 20K blob of JSON. It doesn't sound like much, but at Uber's growth rate saving several KB per trip across hundreds of millions of trips per year would save a lot of space. Even Uber cares about being efficient with disk space, as long as performance doesn't suffer.
This highlights a key difference between linear and hypergrowth. Growing linearly means the storage needs would remain manageable. At hypergrowth Uber calculated when storing raw JSON, 32 TB of storage would last than than 3 years for 1 million trips, less than 1 year for 3 million trips, and less 4 months for 10 million trips.
Uber went about solving their problem in a very measured and methodical fashion: they tested the hell out of it. The goal of all their benchmarking was to find a solution that both yielded a small size and a short time to encode and decode.
The whole experience is described in loving detail in the article: How Uber Engineering Evaluated JSON Encoding and Compression Algorithms to Put the Squeeze on Trip Data. They came up with a matrix of Continue reading
