This post mines publicly available data on the pace of compatibility fixes and feature additions to assess the claim. Thanks to the Web Platform Tests project and wpt.fyi , we have the makings of an answer for the first: Tests that fail only in a given browser.

At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. It's all a bit confusing, and I wrote about this in 2014: [Xen Modes]. When I joined Netflix in 2014, we had begun transitioning from PV to HVM (PVHVM). This recommendation quickly became out of date.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. How would you time time?

Defenders of Apple's monopoly offer hard-to-test claims, but many boil down to the idea that Apple's product is inferior by necessity. There's no point in recommending a better browser because none is available. In 2014, Apple would have enjoyed a profit margin of 50% if it had spent half a billion on browser engineering.

In 2014, we discussed 4 of the top MongoDB GUIs: MongoVue, MongoHub, RockMongo, and Robo 3T (formerly Robomongo), and again in 2016: MongoDB Compass, Robo 3T, Studio 3T, and MongoBooster. It’s further enhanced by an in-place code editor which is also available in all three views. Comparing MongoDB GUIs. Click To Tweet. NoSQLBooster.

SQL Server 2014 added the ability to perform parallel batch-mode grouped aggregation within a single Hash Match Aggregate operator. instructions are available. Still, when the plan generally qualifies for grouped aggregate pushdown, both pushdown (fast) and non-pushdown (slow) code paths are made available. CREATE TABLE dbo.

Devices and networks have evolved too: Alex Russell @slightlylate An update on mobile CPUs and the Performance Inequality Gap: Mid-tier Android devices (~$300) now get the single-core performance of a 2014 iPhone and the multi-core perf of a 2015 iPhone. Modern network performance and availability. Here begins our 2021 adventure.

SQL Server 2014 SP2 and later produce runtime (“actual”) execution plans that can include elapsed time and CPU usage for each execution plan operator (see KB3170113 and this blog post by Pedro Lopes). The following examples use the public Stack Overflow 2013 database ( download details ), with a single index added: CREATE INDEX PP ON dbo.

This approach can be expressed in more formal way by the following equation: where is the data available for analysis, is the space of a retailer’s actions and decisions, is an econometric model defined as a function of actions and data, and is the optimal strategy. This framework resembles the approach suggested in [JK98].

To provide some coherence to the music, I decided to use Taylor Swift songs since her discography covers the time span of most papers that I typically read: Her main albums were released in 2006, 2008, 2010, 2012, 2014, 2017, 2019, 2020, and 2022. This choice also inspired me to call my project Swift Papers. But still, I liked how Moment.js
