Have you recently spun up a new Ubuntu Droplet on DigitalOcean? The other day, when I checked my authentication logs in /var/log/auth.log, I came across several login attempts with random usernames.
We often take security for granted, but it becomes something of great concern once you start to manage servers of your own. If you were to leave your Droplet as it is, it is only a matter of time before hackers guess your login credentials and gain access to your system. Hence, here are some basic security measures you should set up to prevent others from breaking in:
As a result of working on upgrades for this Pokémon Effort Value Calculator, math has been a pretty big part of my life for the past few months, as I’ve been rearranging the games’ formulas for stat and damage calculation to make my own that fit my needs.
One such formula was the EVs needed one, which gives you the amount of EVs you need to invest to raise a stat by n points. Everyone knows that at Level 100, you get 1 stat point for every 4 EV points you invest; but what happens when you’re not at Level 100, or when you factor in stat modifiers like Nature, or item and ability boosts?
RAM stands for Random-Access Memory, but that is something that you can find out just by doing a quick Google search. If you read the results of said Google search to understand what it is, you’ll start running into jargon that can be difficult to understand for a layperson. Here are some examples:
…a form of computer memory that can be read and changed in any order, typically used to store working data and machine code
…is used to load and run applications, such as your spreadsheet program, respond to commands, such as any edits you made in the spreadsheet, or toggle between multiple programs, such as when you left the spreadsheet to check email
These are not bad examples, per se, but if you don’t work with computers a lot, these explanations will seem very abstract. What does working data mean, for example; or why is RAM temporary storage (why not just make it permanent)?
