What Is Antivirus Application?

The term “antivirus software” identifies a wide variety of computer system security courses. While malware is the most prevalent term used, it actually refers to all types of reliability threats. A large number of security businesses use the term “antivirus software” being a marketing term, and customers often assume that viruses happen to be synonymous with these courses. However , malware software defends against a number of types of web based threats, and therefore should be an important part of your overall reliability strategy.

Ant-virus software must be compatible with the operating system. You should search for one that ideal for different operating systems, just like Windows and MacOS, or it may not be compatible with your laptop or computer. If you are uncertain whether the antivirus software will work over a specific equipment, read customer reviews to discover what kind of compatibility concerns it has. Whilst antivirus applications are generally liberated to download and install, it may carry adware and spyware that can harm your computer.

Some antivirus software may count on behavior-based detection, which evaluates the behavior of object and infers it is malicious intention from some of those observations. When a code makes an attempt to perform abnormal https://greatsoftware.pro/best-iphone-chargers-2021 or unauthorized actions, it’s likely malicious. Behaviours that suggest a potential menace include changing system options, modifying a large number of files, monitoring keystrokes, and remotely hooking up to the computer. Some anti-virus software may even discover a program it’s not malicious when it’s harmless.

Running Raspbian in image on Ubuntu desktop

While the title says Raspbian on Ubuntu, the steps will be nearly the same for any ARM linux distribution on any AMD64 Linux desktop. For me, and I suspect most people, what combination is likely to equal Raspbian on Ubuntu.

Download and extract your Raspbian image. In this case I will be using Raspbian Lite and this is the filename of the image: 2019-04-08-raspbian-stretch.img

First, setup: sudo apt install qemu binfmt-support qemu-user-static systemd-container

After the setup, run the following steps every time you want to run a Raspbian image on Ubuntu.

sudo kpartx -v -a ./2019-04-08-raspbian-stretch.img

That will print something like:

add map loop11p1 (253:0): 0 89698 linear 7:11 8192
add map loop11p2 (253:1): 0 8392704 linear 7:11 98304

The first line is the raspbian boot partition, the second will be the rootfs partition.

udisksctl mount -b /dev/mapper/loop11p2

After the prior command, a rootfs mount should appear in /media/<your_username>/. You can copy files into either and they will be placed into the image file you mounted.

sudo systemd-nspawn -D /media/<your_username>/rootfs/

Ctrl-D to exit.

udisksctl unmount -b /dev/mapper/loop11p2

sudo kpartx -d ./2019-04-08-raspbian-stretch.img

Note, a more advanced use might be to copy some sort of initialization script into the image after mounting the image and before running systemd-nspawn. Then, invoke that command something like: sudo systemd-nspawn -D /media/<your_username>/rootfs/ /bin/bash /home/pi/your_script.sh

Dynamic Wireless Network Name (SSID) on Raspberry Pi hotspot

This mostly for any Linux system using systemd, albeit the make_ssid.sh script will need adjusted for where you want to get the ID from. In the example, it uses the Raspberry Pi’s serial number. Mac address could be another good source to use.

make_ssid.sh goes in /etc/hostapd/
The service file goes in /etc/systemd/system/

Kivy on Raspbian using EGL without installing X11

This is aimed more at using the Raspberry Pi with a touch screen for embedded uses, and is not relevant to using it in the Raspbian desktop environment.

Unfortunately, it seems that to just pip install kivy appears to work, but then when you run an example, it complains about missing libraries, and installing those eventually gets you to the point where you need X11 because of the dpkg dependencies being overly broad.

If you build Kivy from source you can avoid that.

Substance Designer SBSPRS/SBSAR file format notes

I have never used Substance Designer, so I’m basing this off of looking at example files.

The SBSPRS files are XML that appear to specify the list and type of parameters used in the SBSAR substance.

The SBSAR file is just a 7-zip file. It expands to:
./assemblies
./assemblies/content
./assemblies/content/0000
./assemblies/content/0000/icon1234567890.png
./assemblies/content/0000/Example.xml
./assemblies/content/0000/Example.sbsasm

The Example.xml file appears to describe the inputs of the node, the outputs of the node, gui layout for the node, and presets to choose for the node.

The Example.sbsasm file starts with the magic word 5342 414d, which are the ASCII values for SBAM. Beyond that, I haven’t figured anything else out about it.

I was hoping that this would be compressed formats, XML, JSON, and/or IFF all the way down.

In case anyone is interested in making USB connectors a bit more kid proof, I recently bought these magnetic USB cables: https://www.amazon.com/gp/product/B074TB8XTL
For the kid’s tablet, I super glue the micro-usb adapter in place. It sticks out about 1/8 in. No more kid destroying USB ports.
It’s like Apples MagSafe for tablets.
For their claim that it will prevent “tripping over cable resulting in smashed phones”, the magnetic pull is strong enough to yank at least some phones off a table when the cord is accidentally pulled (say by tripping on it).
