Faster remainders when the divisor is a constant: beating compilers and libdivide

Daniel Lemire

In some instances, libdivide can even be more efficient than compilers because it uses an approach introduced by Robison (2005) where we not only use multiplications and shifts, but also an addition to avoid arithmetic overflows. I make my benchmarking code available. What if d is a constant, but not known to the compiler?

Observability platform vs. observability tools

Dynatrace

For example, in 2005, Dynatrace introduced a distributed tracing tool that allowed developers to implement local tracing and debugging. With no code changes, Dynatrace extends distributed tracing and code-level analysis to OpenTelemetry data, service mesh, and all data from your serverless computing services.

An Unbelievable Demo

Brendan Gregg

It was 2005, and I felt like I was in the eye of a hurricane. Another difference was that there were few roles in Australia for engineers in 2005, unlike the US. But I _did_ understand these tools, since I had coded similar functionality for my own DTraceToolkit. You can't make this stuff up. They were useful, but.I

Fallacy #8: The network is homogeneous

Particular Software

Around 2005 or 2006, it wasn’t so bad. Most of the code running on the planet, at least the code that mattered, was written in.NET or Java, and interoperability via web services was at least serviceable. Interoperability is painful. Since then, things have gotten gradually worse. First came Ruby and Ruby on Rails.

It’s time to migrate from NAM to Dynatrace

Dynatrace

Every real-user transaction traced down to the code level. We reinvented network-based performance monitoring from 2000-2005, which set us up as the market leader (noted by Gartner in the first APM Magic Quadrant in 2010). Today, the open observability concept looks like an obvious standardization that everyone should follow.

Additional T-SQL Improvements in SQL Server 2022

SQL Performance

If you’ve been writing and optimizing T-SQL code for a while, you’re probably well aware of the many complexities involved with NULL handling. If you’re using T-SQL to compute percentiles as part of your work, these functions should be familiar to you since they’ve been supported in SQL Server 2005 and later. The Distinct Predicate.

Joining the SpeedCurve team

Speed Curve

I started coding web pages in about 2005 and began my web development career in Moscow, Russia, joining a biotech startup. Thanks to SpeedCurve for this opportunity, I am so excited to work along with the veterans of the web performance industry (and just plain talented people), as well as to be closer to the performance community.
