To auto start services in Centos, Redhat or Oracle Linux, you can use builtin chkconfig utility. It is located in /sbin directory. If you are a regular user (non-root), then /sbin may not be in your path. Therefore, you may have to use the full path to access the chkconfig utility.
As i use the same monitor (LG W2486L) on my Nintendo Wii U and my Computer, i never payed attention to the fact that sometimes i couldn’t see some colors just for a wrong calibration on my display.
I do use Adobe Lightroom on this PC to make enhancements to the photos, but how could i know if my display was showing what i need to see?
A friend of mine told me about some videos that could help me to do that, on the link below you can download the videos and check more information about it.
I just used the basic settings and now my display is very better, i can see a better range of whites and blacks.
I made this app for a friend that wanted to play YouTube videos just to listen it’s audio. So it’s very simple, works by sharing the URL from YouTube video with the app or googleing the video. (for instance: go to google.com and type “YouTube lindsey”.
Unfortunately, google removed this app from google play, so its here now.
T2 instances are Burstable Performance Instances that provide a baseline level of CPU performance with the ability to burst above the baseline. The baseline performance and ability to burst are governed by CPU Credits. Each T2 instance receives CPU Credits continuously at a set rate depending on the instance size. T2 instances accrue CPU Credits when they are idle, and use CPU credits when they are active. T2 instances are a good choice for workloads that don’t use the full CPU often or consistently, but occasionally need to burst (e.g. web servers, developer environments and small databases).
htop is an interactive text-mode system-monitor process viewer for GNU/Linux. It aims to be a better ‘top’. It shows a frequently updated list of the processes running on a computer, normally ordered by the amount of CPU usage. Unlike top, htop provides a full list of processes running, instead of the top resource-consuming processes. htop uses color and gives visual information about processor, swap and memory status.
If you’re anything like me, you probably log in and out of a half dozen remote servers on a daily basis. And if you’re even more like me, you have trouble remembering all of the various usernames, remote addresses and command line options for things like specifying a non-standard connection port or forwarding local ports to the remote machine. And sometimes you have to do the same thing in a lot of servers, this post is for you.
Apache web server allows server access based upon various conditions. For example you just want to restrict access to url http://subdomain.domain.com/ (mapped to /var/www/subdomain directory) from 192.168.1.0/24 network (within intranet).
Apache provides access control based on client hostname, IP address, or other characteristics of the client request using mod_access module.
