It was 2005, and I felt like I was in the eye of a hurricane. I was an independent performance consultant and Sun Microsystems had just released DTrace, a tool that could instrument all software. This gave performance analysts like myself X-ray vision. You can't make this stuff up. DTraceToolkit v0.96 They were useful, but.I

Consequently, handling our task becomes a no-brainer: DECLARE @s AS VARCHAR ( 20 ) = '123.456.789,00' ; SELECT TRANSLATE ( @s , '.,' , ',' ) ; This code generates the desired output: 123,456,789.00. As an example, suppose that you need to perform some task per database in your instance. That's pretty neat!

Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken. I'm sure this delivered large performance improvements and I wouldn't try arguing against it. This is exactly what happened on Linux, not just /usr/bin but also /usr/lib and application code!

Since SQL Server 2005, the trick of using FOR XML PATH to denormalize strings and combine them into a single (usually comma-separated) list has been very popular. On more than one occasion, I had to double-check the code was even mine. In the SQL Server 2005 days, I would have offered this solution: SELECT DISTINCT UserID , Bands =. (

With observability, teams can understand what part of a system is performing poorly and how to correct the problem. Traces provide performance data about tasks that are performed by invoking a series of services. The key is knowing what is the root cause of the performance issue. Observability platforms provide context.

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.

T-SQL supports it starting with SQL Server 2005. What’s different about the design of CTEs compared to derived tables is where in the code these three elements are located. However, there are very few cases in T-SQL where without a terminator the code is ambiguous. The elements are sort of intertwined.

The British Standards Institution (2005) defines inclusive design as : “The design of mainstream products and/or services that are accessible to, and usable by, as many people as reasonably possible. When maintenance is needed, it won’t take the team as long to maintain the code because of accessibility and clean code.”.

Performance is a core feature of our company, Instant Domain Search —it’s in the name. I founded Instant Domain Search in 2005 and kept it as a side-hustle while I worked on a Y Combinator company (Snipshot, W06), before working as a software engineer at Facebook. When paired with VS Code the development experience is amazing.
