🦑LINUX SPEED HACK :

[1]. Quick Fixes - Disable unnecessary servicesDisable unnecessary services to make Linux Boot Faster

Linux comes in various flavors bundled with a lot of applications.However,most of us don't even use Linux to its full potential. Depending upon the use of the machine, plenty of services and running programs won’t be needed. And if you are using Linux just for a desktop,then you won’t be needing the default sendmail , httpd, and many other services.You can also turn off many other services if your Linux box is used as a small web server by going to Administration menu,tweaking the Services entry and deselect all of the services you don’t want to start.

[2]. Free up Your Kernel - Disable unnecessary kernel modules

If your Linux box is wired to the LAN/Ethernet,then you don’t need to have a wireless kernel module loaded. More services like smartcard modules and more can be disabled and the load can be taken off from the kernel.This task is a bit Tweaking Linux Kernel is even difficult for Linux Geeks..but its worth its time and learningdifficult requires recompilation of kernel, which is daunting for even the *inux geeks. To do this, you will need the kernel sources and then follow the standard steps for compiling a kernel. You will be having a ride through the internals of your system just disable all of the kernel modules you don’t need.

For added safety,install Bootchart which will tell you if Kernel modules are properly installed and running on your system. Not only will this give you a good list of modules, it will illustrate for you what is happening during your system boot. You can also issue the command

chkconfig –list | grep 3:on

to find out what services are running. Once you know what loading modules you don’t need, you can remove them during a kernel recompilation. While you’re at it, compile the kernel to exactly match your architecture.Make your Linux Faster - Use a Lightweight Linux Distribution

[3]. Take Load Off Linux - Use a lightweight window manager instead of GNOME or KDE

Using a smaller window manager drastically reduces graphical boot time. Instead of having to wait that extra 30 to 60 seconds for GNOME or KDE to boot up, why not wait two to 10 seconds for Enlightenment or XFCE to boot up? Not only will they save you boot time, they will save your memory and the headache of dealing with bloatware.

[4]. CUI ROKZ’ - Use a text-based login instead of a graphical login

The graphical logins do two things: increase load times and create headaches trying to recover from an X windows failure.Most of Linux machines which boot to run level 3 instead of run level 5 will halt at the text-based login, where you only have to log in and issue startx to start your desktop of choice.So CUI login is the way to go.

[5]. The Flying Penguin - Use a lighter Linux distributionLet Your Linux Fly - Use a lighter Linux distribution

Are You a Linux newbie ? Instead of loading the heavyweight SUSE, why not try a DSL, Puppy Linux, or Gentoo? The boot times for these smaller distributions are far faster than the more bloated Fedora (SUSE and even Ubuntu).Loading lighter linux distributions will save you from lot of headaches. Of the larger distributions, OpenSuSE claims to boot the fastest, but between the latest Fedora and Ubuntu, Ubuntu blows Fedora’s boot times away (and that is out of the box,trust me..).

[6]. Get Savvy - Use an OpenBIOS

If you’re tech savvy enough to upgrade your PC’s firmware, you might consider a migration to open source BIOS which Use custom Open bios to meet your machine's needswill allow Linux to actually initialize the hardware as it boots (instead of relying on the BIOS). Also, many open BIOSes can be customised to meet your machine’s specific needs. If you don’t go the open BIOS route, you can at least configure your BIOS to not search for a floppy drive that’s not there or to boot directly to the first hard drive (instead of the CD drive first).

[7]. DHCP woes - Avoid dhcp

If you are working on a home network (or a small business network) where address lease isn’t a problem, go with static IP addresses. This will keep your machine from having to call out to a dhcp server to get an IP address. If you take this approach, make sure you configure yourAvioding DHCP and Unplugging Hotplug will surely speed things up

/etc/resolve.conf

to reflect your DNS server addresses as well.

[8]. Hotplug unplugged - If you can spare it, get rid of hotplug

Hotplug is the system that allows you to plug in new devices and use them immediately. If you know your server won’t need this system, delete it. This will cut down on boot time. On many systems, hotplugging consumes much of the boot time. Removing hotplug will vary depending upon the distribution you use.

NOTE: udev has, for the most part, replaced hotplug. But if you’re running an older distribution, this does apply.Are You Daring enough to mess with initng ?

[9]. If you are REALLY daring, you could give initng a try

The initng system serves as a replacement for the sysvinit system and promises to drastically decrease boot times in UNIX-like operating systems. If you would like to see the initng system in action, you can give the Pingwinek livecd a try.

[10]. HackerPunk - Use a hack with Debian

If you’re using Debian, there is a simple hack you can use to switch your startup scripts to run in parallel. If you look at Hack your debian to run startup scripts in parallelthe

/etc/init.d/rc

script, you will see:

How to Watch Two Videos Simultaneously on Galaxy Note 20 and Galaxy Note 20 Ultra ?

1) Step 1. Install SoundAssistant
To do this, you need to install the Samsung SoundAssistant app. If this program is not yet available on your Galaxy Note 20, you can download it

https://galaxystore.samsung.com/detail/com.samsung.android.soundassistant?session_id=W_eb2e230a3af7edf07ba8cc36b95b3116

Using the application, you can start two videos, change the volume step, add an equalizer to the volume bar, etc.

2) Step 2. Activating Multi Sound
Launch the app and activate the Multi Sound switch. You will need to select an application. On the new page, select the application to broadcast the videos you want to watch simultaneously. Once selected, this app will play audio even if you have started a video from another source.

3) Step 3. Splitting audio
Go back to the SoundAssistant main page and select Separate app sound under the previous option. Activate the switch on the next page and click Select. You will see the page as in step

Select the same application from the list as in step 2.

Once selected, this application will be able to output audio to a separate audio device. Without enabling this function, when you play two videos, the sound of two applications will be output from one speaker or headphones at the same time. The default is any Bluetooth-connected audio device. Do not change this setting.

4) Step 4. Check the result
Connect the Bluetooth device to your smartphone and launch the video viewing application that you set in the Multi Sound and Separate app sound settings. Play the video. The sound should be output to the Bluetooth device as usual. Use split screen mode to open another app and play the video in it. The sound will come from the smartphone speaker.

It should be noted that the audio from the speaker cannot use the Samsung Dual Audio function to output to another speaker or Bluetooth headphones. If you want to split the audio but don't want it to come from your smartphone speaker, plug in a pair of headphones via USB-C. For example, these are included with these smartphones. The sound will be the same as that coming from the smartphone speaker, but different compared to Bluetooth.
