Where a high availability design once worked well, it can no longer keep up with more complex requirements. The majority of SPOFs are a consequence of scale, where designs that were once adequate (excellent, even) no longer meet evolving, more complex requirements. Failover is essential to minimizing downtime.

This lack of transparency is by design and provides Apple deniability while simultaneously setting low expectations, making them easier to exceed. A 2017 attempt to revive it was shot down in 2018 by Apple engineers without evidence or data. However, aside from the reading of tea leaves, there's no way to know if work is progressing.

If you don’t have well-designed and small columns for this composite primary key, it could enlarge all of your secondary indexes. Inappropriately designed queries may not fully utilize partitioning benefits, leading to poor performance.

Here are my top five most-played tracks of 2017’s 70,000 minutes: However, after recently discussing one of my all-time favourite tracks with a friend, and, bizarrely enough, with Nu:Tone himself, I decided that I wanted to start taking my listening a little more seriously. At home, I’m used to just streaming Spotify through an Amazon Echo.

Richard Thaler won the 2017 Nobel prize in Economics for his work on Behavioral Economics. In industry, generally due to time-to-market restrictions, we tend to think extremely short term with evolutionary design changes rather than riskier revolutionary ideas that have a longer timeline for returns.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Engineering is the discipline of designing solutions under specific constraints. So what did $650, give or take, buy in late 2017 or early 2018?

One approach is the implementation of failover mechanisms.

Add onto that the yawning chasm between low-end and high-end device performance thanks to chip design factors like cache sizes, and it can be difficult to know where to set a device baseline. We now have everything we need to create a ballpark perf budget for a product in 2017.

Without a strong alignment between dev/design and business/marketing teams, performance isn’t going to sustain long-term. Setting Realistic Goals.
