  • I’m going to answer your points below. Not because I want to tell you to move to Linux, but because the information you state is incorrect. Linux is not for everybody. It works for millions of people and it works for me, but that doesn’t mean it will be what you’re looking for.

    In order:

    1. There are no .exe files. Neither are there any on MacOS, iOS, Android, or anything else that isn’t Windows/DOS. To start software requires that it’s on the search path in exactly the same way that Windows requires. You can see what that is with the command: echo $PATH. Most Linux distributions have a graphical user interface which features icons and menus, but if you don’t want that, you don’t need to install it.

    2. You absolutely can, but it doesn’t work the same way as Windows, because it’s not Windows. You can for example login to Linux because the login manager started at system startup. You see a desktop after logging in because there’s a startup system for your account. The printer works because the software driving the print queue is started.

    3. Wine is a tool. It’s not a replacement for Windows. It’s not intended to be. It’s intended to help users and developers make Windows software work better on Linux.

    4. LibreOffice is one of many office suites. I have been using it as my productivity software for 25 years in my company and I’m not at all disappointed to have escaped the Microsoft Clippy, Ribbons, Office365 abominations.

    5. I have used Libre Calc for most of my numerical analysis processes. I used real tools like R and gnuplot when I was analyzing terabytes of data.

    6. The terminal is a tool. I use it daily. At any time there’s a dozen of them open. Not everyone needs a terminal, but there are plenty of things that you can only do in a terminal. A random example, list all the files in your account, group them by extension, then add up how much space each extension takes. In case you’re wondering:

    find ~ -type f | egrep -o "\.[a-zA-Z0-9]+$" | sort -u | LC_ALL=C xargs -I '%' find . -type f -name "*%" -exec du -ch {} + -exec echo % \; | egrep "^\.[a-zA-Z0-9]+$|total$" | uniq | paste - -

    Linux is not Windows. It never was and it never will be, neither is any other operating system. The community around Linux is helpful, the ecosystem is vibrant and it’s free. If you want to pay for support, you can. If you don’t, there’s plenty of opportunity to do your own thing.

    If you want it to be like Windows, you’re going to be very disappointed.















  • One of my colleagues managed to accidentally run something like rm -rf /var/tmp/ * on a Solaris machine that was the mail server for the entire organisation.

    After the command finished they realised that the inadvertent space in front of the asterisk meant that the command did slightly more damage than intended.

    They were told to leave the machine running to be able to fix it from a backup, but they rebooted instead.

    An open file is still usable even after it’s been deleted, so the kernel and shell were still up and running … before the reboot …

    If I recall, it took weeks to fix, involving floppy disks, Sun engineers and much egg on face.




  • I don’t know, but I doubt that the frequency response of a mobile phone microphone is either linear or consistent across sound level.

    I don’t even think you could compare two sounds with different frequencies, but I don’t know.

    I suspect that calibration of any such thing would require a whole lot of infrastructure, consider for example the angle of the phone in relation to sound and the impact of holding the phone in how it affects vibration and noise damping.

    You might be able to use a calibrated sound level meter and pair it via Bluetooth with your phone, but I think that’s going to be as close as you might get.

    In the past I’ve tried a wired USB microphone, but the OS isn’t real-time, so the jitter was horrendous. A pi would give you a more consistent result.
