Feed: Planet MySQL; Author: Tiago L. Alves; Gaming, banking, telcos, and online services all are powered by fully-redundant and fault-tolerant software systems. At the heart of those systems, you can find MySQL Cluster — a distributed in-memory database having a minimum of five-9s availability (around 5 minutes a year). This open-source database provides nearly-linear scalability and real-time querying predictability at the microsecond level.To achieve such higher availability it’s crucial to ensure that each release is thoroughly validated. Thousands of automated tests are run daily, for different versions and platforms to ensure defects are detected early and fixed. Testing is everyone’s ... Read More

Feed: Cloudwards. Author: Ben Stockton; Avast is among the best free antivirus software on the market, while Webroot uses different methods to protect your devices, compared to its competitors. To decide which is best, we’re pitting Webroot and Avast against each other in a head-to-head comparison. Although the services cover different markets — with Avast appealing to the masses and Webroot targeting a niche audience — they’re more similar than they are different. That said, some areas, such as protection, are more important than others, pushing one of the services ahead.  This Webroot vs. Avast comparison can’t cover everything, though, ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Recently, at Percona Live Europe 2019, Dimitri Kravchuk from Oracle mentioned that he observed some unclear drop in performance for MySQL on an ext4 filesystem with the latest Linux kernels. I decided to check this case out on my side and found out that indeed, starting from linux kernel 4.9, there are some cases with notable (up to 2x) performance drops for ext4 filesystem in direct i/o mode.So what’s wrong with ext4? It started in 2016 from the patch that was pushed to kernel 4.9: reported and discussed in LKML. As a result ... Read More

Feed: Planet MySQL; Author: Mark Callaghan; How do you use an LSM for analytics? I haven't thought much about it because my focus has been small data -- web-scale OLTP since 2006. It is a great question given that other RocksDB users (Yugabyte, TiDB, Rockset, CockroachDB) support analytics.This post isn't a list of everything that is needed for an analytics engine. That has been described elsewhere. It is a description of problems that must be solved when trying to use well-known techniques with an LSM. I explain the LSM challenges for a vectorized query engine, columnar storage, analytics indexes and ... Read More

Regularization is a way of avoiding overfit by restricting the magnitude of model coefficients (or in deep learning, node weights). A simple example of regularization is the use of ridge or lasso regression to fit linear models in the presence of collinear variables or (quasi-)separation. The intuition is that smaller ...

Feed: Liquid Web. Author: Andrew Hartnett; First of all, what is DevOps? DevOps is short for Developer Operations and it is a newer approach that combines both development and operational tasks to automate and speed up software development practices and reduce release cycles for fast-growing companies. DevOps is built on the concept of teamwork and aims to unite teams that were traditionally kept separate and siloed, and reduces the development lifecycle for faster scalability. Once companies have decided which their business needs and objectives are, they need to start small and work towards adopting the DevOps model across the entire ... Read More

Feed: Big Data Made Simple. Author: Sherley Alaba. Just imagine you wake up on a vibrant Monday and head to your office. You’re hardly settled on your seat in the office when your boss calls you up for a meeting.

He is going to replace you from today.”Well, this is not a very common nightmare for many right now, but it would be a common fear of millions of people across the planet in about a decade.
