How to remotely query indexed caches in Data Grid 8 | Red Hat Developer
The Red Hat Data Grid is a hosted data storage platform that offers different levels of caching for fast access to data in memory. Well-chosen indexes allow the data store to fetch results faster than non-indexed caches. This article demonstrates how to create indexes in Data Grid and use them in a Java application built on Spring Boot. Then we will run and test the application in a container on Red Hat OpenShift.

Day 48: inset 0
On day 9 I’ve talked about the inset shorthand properties inset, inset-inline, and inset-block. I don’t believe that I will need those often, but inset can come in handy when you want one element to fill another element entirely.

The uncertain question of how much RAM our servers need
Even with a metrics system, this isn't a straightforward question to answer, and in fact we haven't tried to do any sort of systematic assessment.

The initial deployment is the one time when the choice of RAM amount is basically free.

HackSpace magazine’s mince pie tutorial
Christmas is all about food and, if there’s one food that we can’t do Christmas without, it’s mince pies. These little sweet fruit delights are so emblematic of the season. However, too often we see sub-standard mince pies churned out by the million by supermarkets with more of an eye on shelf life and profit per unit than quality. In this article, we’re going to go through our technique for making mince pies that we’ve honed over a couple of decades.

Configure Your Mac to Allow Vintage Computers to “Dial In”
I learned that in a few simple steps you can setup a listener macOS daemon that will allow an incoming telnet connection to a specified port and present a shell session with a login prompt where you can login and execute terminal commands.

(Another nice terminal-based IRC client is WeeChat, by the way.)

Adventures in updating
Before I go to the trouble of installing the latest version of Apache, I want to ensure my updates to mod_litbook will compile on the lastest version of Apache. I've been developing it using Apache 2.4.38, a version from 2019 (and because I'm using mod_lua it's vulnerable to CVE-2021-44790). So I pull down the latest version (as of this writing, the latest stable version is 2.4.54) and start compiling.

The Word “Value” in CSS
When you say “value” in CSS, you might think you know what it means. But if you look closer — especially at the spec — you’ll find there are lots of different meanings for the word “value” in CSS, each one different than the next.
