When it comes to CSS, there are always new tools being introduced to help us transform styles in a more fast and efficient manner. In 2013, PostCSS was released but it wasn’t until mid-2015 when a lot of buzz really started to take place in the development community around PostCSS. Today, in 2018, PostCSS is still widely used in the development community and the project itself is still actively maintained by a large community of contributors.

Windows has long had a reputation for slow file operations and slow process creation. Have you ever wanted to make these operations even slower? This weeks’ blog post covers a technique you can use to make process creation on Windows grow slower over time (with no limit), in a way that will be untraceable for most users! And, of course, this post will also cover how to detect and avoid this problem.

If you’re using Amazon S3 for a CDN, it’s possible to serve compressed, gzipped files from an Amazon S3 bucket, though there are a few extra steps beyond the standard process of serving compressed files from your own web server. The post Serving Gzipped JavaScript Files From Amazon S3 appeared first on The Polyglot Developer.

SQL Server trace, the most common tool DBAs use to evaluate query performance, provides the ‘logical reads’ counter on which many DBAs rely for evaluating a query’s I/O performance. In this article, we will examine this counter’s true meaning and provide examples that prove it can sometimes be quite misleading… I am sure you have […].

An essential part of database performance testing is viewing the statistics generated by the database during the test and in 2009 HammerDB introduced automatic AWR snapshot generation for Oracle for the TPC-C test. With this feature Oracle generates a wealth of performance data that can be reviewed once the test is complete. However what if you want to review performance data in real time as the test is running?

I was recently tasked with a project where I needed to gather data from Stack Overflow so it could be easily evaluated without having to dig around the website. Stack Exchange has many REST APIs available, some of which that don’t even need tokens or authentication, so it came down to how I wanted to consume this data. In this tutorial, we’re going to see how to consume question and comment data from the Stack Exchange API using Golang and then export it to comma separated value (CSV

System-versioned tables, or temporal tables, are a typical feature of proprietary database management systems like DB2, Oracle and SQL Server. They also appeared at some point in PostgreSQL, but only as an extension; and also in CockroachDB, but in a somewhat limited fashion. The MariaDB® implementation is the first appearance of temporal tables in the MySQL ecosystem, and the most complete implementation in the open source world.

There are broadly two dominant approaches used to organise teams in modern organisations that have moved beyond traditional activity-oriented organisation design (organising people by their specific skill). One perspective is to organise teams ‘vertically’, aligned with the company’s products. Google might have a Google Drive department, a Google Maps department, an AdWords department and so on.

This is a very typical FAQ and although detailed in the documentation some extra details may help in sizing and configuration. For a really quick answer create a schema with 250-500 warehouses per server CPU socket for more details size as follows. . The official TPC-C test has a fixed number of users per warehouse and uses keying and thinking time so that the workload generated by each user is not intensive.

** Having spent my recent years “in the real world”, working with many users, I’ve learnt that a particular new feature does not necessarily excite users as much as one might expect. MariaDB 10.3 however actually has some very interesting features that users do get excited about. So that’s great! My session at Percona Live Europe in Frankfurt is going to be best for people deploying MariaDB or related infra, who haven’t had a chance to explore what the various featu

This post walks through how to export data from MySQL® into JSON format, ready to ingest into MongoDB®. Starting from MySQL 5.7+, there is native support for JSON. MySQL provides functions that actually create JSON values, so I will be using these functions in this article to export to JSON from MySQL: JSON_OBJECT JSON_ARRAY These functions make it easy to convert MySQL data to JSON e.g. mysql> SELECT json_object('employee_id', emp_no, 'first_name', first_name ) AS 'JSON&#
