Customer service is central to the overall customer experience that all consumers are familiar with when communicating with companies. That experience is often tested when we need to ask for help or have a question to be answered. Unfortunately, we've become accustomed to providing the same information multiple times, waiting on hold, and generally spending a lot more time than we expected to resolve our issue when we call customer service.

When Uber launched in 2009, our mission was simple: make transportation as reliable as running water everywhere, for everyone. While our mission remains the same today, the number of Uber use cases have grown dramatically, motivating our engineers to think … The post Engineering On-Demand Transportation for Business with Uber Central appeared first on Uber Engineering Blog.

Imagine you’re a manager on a large software project. You’ve got about a month to go before the intended deadline and your team appears to need at least 3 more months before being done. What do you do? Many come under the temptation to start a so called “death march”. It essentially means having folks work as many hours as possible: nights, weekends, whenever.

When we think about value, we think in terms of hard measures like increasing revenue or decreasing cost, or soft measures like increasing customer satisfaction or reducing customer friction. This all sounds great, but we know in practice that value is not as concrete as we would like to believe: projections are conjecture, there are multiple forces at work that determine the result we get, and counterfactuals can't be proven to know for fact whether we'd have been better off doing something dif

This article titled " Wartet nicht auf Perfektion – lernt aus euren Fehlern! " appeared in German last week in the "Digitaliserung" column of Wirtschaftwoche. "Man errs as long as he doth strive." Goethe, the German prince of poets, knew that already more than 200 years ago. His words still ring true today, but with a crucial difference: Striving alone is not enough.

CPU flame graphs visualize running code based on its flow or stack trace ancestry, showing which functions called which other functions and so on. But with Java, there's another way to visualize the same CPU workload which provides some additional insight: **a Java package flame graph**. Instead of visualizing the stack trace hierarchy, this visualizes the Java package name hierarchy.

Pretty much anyone who knows adtech will tell you that header bidding is the future of the industry. Header bidding allows publishers to field ad bids in the header of a webpage, which is before anything else (including other ad placements) loads. This allows publishers to establish a “premium” auction instead of the typical real-time bidding system.

In a previous blog post , I discussed a very complex and intricate process: how my family unloads our dishwasher using a chain of responsibility. We examined a happy-path scenario in which each person hands a dish to the next. Every step takes the same amount of time, and the process hums along like clockwork. You can almost hear us singing “Whistle While You Work” while we gleefully put away dishes.
