rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well. rsnapshot is written in Perl, and depends on rsync. OpenSSH, GNU cp, GNU du, and the BSD logger program are also recommended, but not required. All of these should be present on most Linux systems. rsnapshot is written with the lowest common denominator in mind.

Indexing files and folders (directories) of storage devices is good and bad at the same time. Spotlight always indexes your macintosh storage, so you can type any program to execute it or a file name to search for it. But indexing external storage volumes is consuming too much horsepower and time of your mac computer. To make your pendrive and external harddisk plug-and-play, we are going to disable spotlight indexing for external storage volumes on your mac machine. Disable Spotlight indexing for external storage drives / volumes First let’s open Terminal application, then type this command and click ENTER (Return) key on your keyboard.

two types of compression You can reduce the size of images by compression. But there are two types of compression. lossless compression lossy compression best website to compress images There are too many programs, apps and websites to compress images. But I see that https://compressor.io/ website is the best one. In this website you have both types of compression. The lossless compression dosn’t lose quality, yet lossy compression make image lose a tiny amount of details. why compress images If you have too many images which consume a huge amount of size / space, just compress them lossless-ly and store them in less space.

what is lazy-loading Lazy-loading means load this element on demand. We use the lazyloading technique to speed up the web page load time. using lazyloading with images Sample code for image element with lazy loading enabled. <img width="" height="" loading="lazy" src="" alt="" /> The loading="lazy" is to load the image on demand. width="200" and height="400" to save the space for the loading image. src="" for the image url. alt="" to give a description for the image for accessibility purposes. We us this CSS code snippet to make images responsive. img {max-width:100%;height:auto;} using lazyloading with iframe Just add loading="lazy" to the opening element of iframe like this.

How to set the GOGC value ? You can set its value in the terminal like this. GOGC=200 Or you can change it in yaml file of the environment variable when using docker or kubernetes. What is the default value of GOGC ? The default value of GOGC is 100 which means that the garbage collection process will run when the allocations doubled from previous allocations count. What can I do to reduce the effect of garbage collection in Go ? If your Go program has a large static data set, set the GOGC to a smaller percentage; for example GOGC=50.

If you already have a bitmap image in your code, just use this code snippet. bmp = bmp.copy(Bitmap.Config.RGB_565, true); That code will recreate the bitmap image as a mutable. So you can edit that bitmap image on canvas as you like. But if you do not have a bitmap image in code, create a new one using this code snippet. Bitmap bmp=Bitmap.createBitmap(img.getHeight(),img.getWidth(),Bitmap.Config.RGB_565); where img is another bitmap image you want to make a new one with the height and width of it. If you want to create one from scratch here is the code snippet. Bitmap bmp=Bitmap.createBitmap(400,700,Bitmap.Config.RGB_565); After that, create a canvas and pass the bitmap image you have.

Boot Optimization use sudo systemd-analyze critical-chain to get the most time consuming services. If you don’t need those services just disable them by this command sudo systemctl disable service-name.service and replace the service-name with the name of the service you want to disable. BIOS Optimization Just disable any feature you do not use such as fingerprint scanner. To reboot into your BIOS settings, use this command sudo systemctl reboot --firmware-setup. Battery Optimization Use tlp to manage your battery, and use powertop to get the power consumption statistics. Install tlp and powertop using this command sudo apt install tlp powertop. To enable tlp to manage your laptop battery, run this command in terminal sudo systemctl enable tlp.

The problem occured after installing proprietary Nvidia graphics driver using those commands. sudo apt-get update && clear && apt-cache search nvidia-[0-9] | grep 'binary driver' sudo apt-get purge nvidia* sudo apt-get install nvidia-340 nvidia-settings sudo nvidia-xconfig The fix is to let the built-in ubuntu-drivers program decide automatically which graphics driver to install. Open the terminal and type this command to update the apt repositories. sudo apt update Then, remove all packages started with nvidia using this command. sudo apt remove '^nvidia' After that, let the apt remove not needed packages automatically using this command. sudo apt autoremove Finally, let ubuntu-drivers automatically install the suitable proprietary Nvidia graphics driver for your GPU.

First step: create a utilities.sh file to add all your bash functions in it. 2nd step: add your bash function/s like this. ## utilities.sh convertMP4toMP3(){ echo -n "Enter source mp4 file : " read sourceFile echo -n "Enter destination mp3 file : " read destFile avconv -i $sourceFile -vn -acodec libmp3lame -ac 2 -ab 160k -ar 48000 $destFile } I created a bash function to convert mp4 video file to mp3 audio file from command line. 3rd step: source the utilities.sh Bash file source utilities.sh Finally, you can call the function from the command line (terminal) and use it like this.

First things first, install the required software packages. sudo apt-get install ffmpeg && sudo apt-get install libavcodec-extra-53 Then use it. For FFmpeg with Constant Bitrate Encoding (CBR) ffmpeg -i video.mp4 -vn \ -acodec libmp3lame -ac 2 -ab 160k -ar 48000 \ audio.mp3 or if you want to use Variable Bitrate Encoding (VBR) ffmpeg -i video.mp4 -vn \ -acodec libmp3lame -ac 2 -qscale:a 4 -ar 48000 \ audio.mp3 If it says ffmpeg is depricated use this command instead. avconv -i video.mp4 -vn -acodec libmp3lame -ac 2 -ab 160k -ar 48000 audio.mp3 The meaning of arguments argv meaning -i input file name -vn disable video recording -acodec force audio codec to libmp3lame -ac set the number of audio channels -ar set the audio sampling frequency I hope this helps.

use android-gif-drawable library add the following dependency to build.gradle file of your project. dependencies { implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.19' } Use the view in XML file like this. <pl.droidsonroids.gif.GifImageView android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/src_anim" android:background="@drawable/bg_anim" /> For more customization and code, see the docs here. use VideoView on Android You can use VideoView to show the GIF image. But the library is more efficient and smooth. use ImageView on Android Use ImageView and Split the GIF file into several images and then apply animation to it. It is complicated and not worth it because the library is more efficient and elegant. use Glide library add the dependency to build.

There are at least 3 ways to put imageview on another imageview. Simple Order This way is just put the imageview after the other imageview in XML file. It is simple like that. The first view will be underneath the second one. Using FrameLayout <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <ImageView android:id="@+id/imageView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/t" /> <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" /> </FrameLayout> The second image will be on top. Put imageview on another imageview exactly <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/white" > <ImageView android:id="@+id/inside_imageview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="5dip" android:layout_marginTop="5dip" android:src="@drawable/frame" /> <ImageView android:id="@+id/outside_imageview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@id/inside_imageview" android:layout_alignBottom="@id/inside_imageview" android:layout_alignLeft="@id/inside_imageview" android:layout_alignRight="@id/inside_imageview" android:scaleType="fitXY" /> </RelativeLayout> As you can see, the second imageview has those properties.

Here is the code snippet in C programming language. #include <stdio.h> int main() { int a, b; a = 11; b = 99; // to take values from user input uncomment the below lines − // printf("Enter value for A :"); // scanf("%d", &a); // printf("Enter value for B :"); // scanf("%d", &b); if(a > b) printf("a is greater than b"); else printf("a is not greater than b"); return 0; }

Elixir is a dynamic functional compiled language that runs over an Erlang Virtual Machine called BEAM. Erlang and its BEAM is well known for running low-lattency, distributed and fault-tolerant applications. Elixir was designed to take all that advantages in a modern coding language. Elixir data types are immutable. In Elixir a function is usually described with its arity (number of arguments), such as: is_boolean/1. File Types .exs => Elixir script file .ex => Elixir regular file .beam => Compiled Elixir file Compile and Run Elixir code elixir <script_file>.exs => run a script file elixirc <file>.ex => compile a file to Elixir.
