Few years ago I had a collection of maybe fifteen old disks, which I wanted to get rid of, by means of recycling. First I wanted to check the content and then format all so I put them in an external enclosure. It turned out that some disks were unusable. A closer inspection showed that these were all a certain brand and type (Forgot whether it was Seagate or Maxtor or WD). These disks would probably still do fine in a desktop or server computer (Which I no longer had at home) but not with the external enclosure. Perhaps your enclosure is the bottleneck here as well.
TIL that Snapchat is an app used in 2024 without E2EE, Wikipedia article on Snapchat :
Encryption
In January 2018, Snapchat introduced the use of end-to-end encryption in the application but only for snaps (pictures and video), according to a Snapchat security engineer presenting at the January 2019 Real World Crypto Conference.[138][139][140] As of the January 2019 conference Snapchat had plans to introduce end-to-end encryption for text messages and group chats in the future.[141]
Arch Linux, rolling Linux distribution, would give you the newest stable software, with probably new application features, but you can use distrobox, podman-toolbox, VirtualBox, KVM (QEMU) or a live Linux cd image to play with Arch Linux every now and then, without having to install it :)
If you a home user with your computer or laptop inside a LAN you would not really need a firewall, unless you start to use applications which expose its ports to 0.0.0.0 rather than 127.0.0.1 (I believe Redis server software did this a few years ago) and do not trust other users or devices (smart home devices, phones, tablets, modems, switches and so on) inside your LAN.
If you are running a server with just a few services, for example ssh, smtp, https, some hosting company people I knew argue that no firewall is needed. I am not sure, my knowledge is lacking.
Application firewalls, watching also outgoing traffic :
If you compare Linux with some other Operating System you will see that on Linux for years an application firewall was non existing. But there is a choice now : opensnitch This can be useful if you run desktop applications that you do not fully trust, or want more control.
This suggests that if you can build the ROS 1 from source, you have Flatpak and Snap as option, and maybe also AppImage.
Besides that there is also Linux KVM (QEMU) which may perform better than VirtualBox. Cannot find a good page for Ubuntu on it, but here’s the KVM entry of the excellent Arch Linux wiki wiki.archlinux.org/title/KVM
Yes, sure thing, I can imagine that, with millions of people using WhatsApp, Signal and what not. I can also imagine that not everyone on the planet has a smart phone and Internet access yet, due to poverty or other reasons. And in the Western world there are likely still elderly people who have never even touched a smart phone and have a dumb phone. This new app could be useful for people who still want to use 2G with dumb phones.
