      • Notebook Check MNT Pocket Reform: New 7-inch Linux laptop launches from US$899

        MNT Research has finally launched the Pocket Reform, roughly 9 months after it presented the mini laptop. As we discussed last June, the MNT Pocket Reform has a 7-inch LCD panel. It now outputs at 1,920 x 1,200 pixels rather than 1080p, though. Additionally, the MNT Pocket Reform has 8 GB of DDR4 RAM and 128 GB of eMMC flash storage, with a MicroSD card reader and an M.2 2280 slot in place for storage expansion.

        Moreover, the mini laptop has an ortho-linear matrix keyboard with 60 Kailh Choc White mechanical switches, N-key rollover and RGB backlighting. Also, the MNT Research has included four mouse buttons and a micro-optical trackball. Meanwhile, the MNT Pocket Reform has an 8,000 mAh combined battery capacity that should last up to 4 hours charges via a built-in USB port.

      • Linux ITEmanuele Rocca: Disposable Debian VMs with debvm

        Some notes on using debvm, an amazing piece of software I’ve started using
        only recently.

        Create a new virtual machine:

        $ debvm-create

        You now have a virtual machine with Debian Sid of your host native
        architecture (probably amd64). The image file is called rootfs.ext4. You’ve
        got 1G of disk space in the VM.

        You can now just run the VM! You will be automatically logged is as root.

        $ debvm-run

        Experiment in the VM, run all the sort of tests you have in mind. For example,
        one thing I commonly do is verifying that things work in a clean environment,
        as opposed to “on my machine”.

        I’ve been using rsync for years and still did not know its full powers. I just wanted a quick and

      • Scott Williams (vwbusguy): Fedora at SoCal Linux Expo 20x

        Fedora at SoCal Linux Expo 20x

        The So Cal Linux Expo again returned to Pasadena, CA and Fedora came back as an exhibitor!  I have now attended SCaLE every year since 2010, shortly after I moved to Calfornia.  Since the last SCaLE was in late July, there was less time between them.  As a result, I noticed a few things that contributed to this year’s SCaLE being an especially special year: Many larger corporate vendors who were at SCaLE last year didn’t come back this year, so it felt like there were more hobbyist and community groups to fill in the space.  At the same time, many who had not been travelling due to COVID returned for the first time in years.  It resulted in SCaLE feeling a bit more geniune this year with a crowd of people who largely knew what Linux and open source are about and were excited to be there.

      • Stopping Short of the Infinity

        Though not related directly to this quote, what comes to mind is tangential. Tangential ideas toot my muffin. They enhance the darkness that extends from the membrane surrounding this house into the vast cosmos, stopping just short of the infinity peering back and sizing up said membrane, pining for its dissolution.

        I get intermittent lectures from my mother about *tipping*. I’m not against tipping itself. I’ve been known to throw money around practically at random at times. However, I certainly have problems with *tipping culture* in the good ol’ USA. And how does *tipping culture* in the good ol’ USA relate to Woodbury’s Soap?

      • Fundamental Limitations

        So in gemini there is a 1024 byte limitation on the URL; this is by design. Softwares can have a fixed buffer, and you’ll know whether some micro device (presumably with hairball SSL handled, elsewhere) will be able to deal with the protocol, or not. If there were no limitation (there still is one) that would rule out many smaller devices that either cannot allocate sufficient memory, or where the processing would become too slow. Some will argue that the modern web had already become too slow.

      • How artificial intelligence builds ultimate police state

        Twenty years ago, the United States government still reeling from the Sept. 11, 2001, terrorist attacks, began scaling up its surveillance capacity. There was “Total Information Awareness.” There was even a controversial plan to enlist letter carriers and even librarians to keep an eye on the populace.

        Back then, I found this to be somewhat laughable. Even if the U.S. government was able to scoop up all sorts of information off the Internet and telephones, it will represent a massive trove of data that no humans could go through and analyze. Even if the Intelligence Community enlisted the entire population of the United States that would be humanly impossible. So my reaction to this was, what could they do?

      • Setting up vits-models to generate Waifu voices on demand

        I got my hands on LLaMA and I’m trying to build an automatic translation bot and throw it into VRChat for assist in language exchange (credit to my friend Pichu for the idea). Thinking about it. Why not make the voice as quite as possible? It fits the weeb colture there. The standard TTS tools, even Festival can only do standard, boring speech. After a few seconds googling, I found a plethora of deep learning based voice synthesis models on HuggingFace. vits-models have a huge collection of voices.

      • Minimalist Computing

        I’ve spent the last couple of months familiarizing myself more with Gopher and exploring gopherspace. This is in addition to Geminispace. I have such a calming sense of peace when I’m exploring gopherspace without the inundation with ads or video or photos that so prevalent on the modern web. I haven’t had the luxury of exploring as much as I want do since my computer is no longer my own un-shared private system any longer after a series of hardware failures and accidents with other household devices, so for the moment I am forced to share my computer and I loathe it. Work continues on my tutorials but due to the shared computer in addition to other factors it is taking much longer that anticipated. I remain hopeful that I will have my computer back to only my individual use again within the next two months.

        I don’t think I’ve explored enough to do a apples to oranges comparison of gopher vs gemini but I have been reading up on many others’ thoughts on the subject. I do know for sure however that I prefer Gemini’s requirement for SSL encrypted connections. I understand that the way that Gemini gemtext is written, the display of the content is solely determined by the client, but I do know that I really prefer the old “look and feel” of the gopher way of doing things with text being plain text only file, hard wrapped to 72 characters and left justified. It reminds me of a RFC text file and I love that format and look much more than the HTML versions.

      • Internet/Gemini

        • Maiden Voyage

          So I’ve left smol.pub, ditched my old pseudonym, Sud0nim, and adopted a new one, Lesogorov.


          Sud0nim, wasn’t doing it for me anymore. I came up with it in 2020 and had been using it since then, but I didn’t feel ever truly tied to it. I thought it was a fun play on the word “pseudonym”, while incorporating my interest in Linux with the “sudo” command. It also didn’t have any ties to any identifying information to make it fairly anonymous. Pretty quickly I realized I was far from the first person to select that as my online handle, which resulted in me needing to make it “Sud0nim” or “Sudon1m” or “Sud0n1m”, which just pushed me further away from the name. Plus when I wrote my piece on the struggles of being anonymous online, I got a very reassuring email from Ploum that reassured me not to worry so much about being tied to my online identity. This diminished my liking of the whole pseudo-anonymous aspect to the name. So when I decided to spin up my own Gemini server, I got the domain sud0nim.online and got it all ready for publishing, but stopped and started from scratch. If I wanted to put work into this it ought to be a name I feel tied to. I chose “Lesogorov” a Russian patronymic for “Son of the forested mountains”, it’s not a very common last name in Russia so it’s unique enough for me, and it represents my interest and connection to nature, especially mountains and thick forest. Plus it reflects my interest in Russian culture and the language, and in Russian cursive it is easy to distinguish each letter, which can’t be said of all names/words.

        • R code for calculating woody productivity and vital rates

          I have developed some R code to use with data from the SEOSAW[1] database to calculate woody productivity and vital rates according to Talbot et al. (2014), Kohyama et al. (2018) and Kohyama et al. (2019). I’ve archived the code as a Github repository[2] in case anybody wants to use it.

        • Using Nix to configure Neovim

          Over the past week I’ve been experimenting with using Nix to configure NeoVim, and its been going really well. I’ve been playing with using Nix as a package manager since the beginning of the new year when I bought a new machine, and its been an absolute breeze with installing new command line tools. However, by installing NeoVim via Nix, it wasn’t then picking up my rc files. Couple that with the fact that I’ve been putting off migrating to NeoVim’s built-in package manager to manage all my packages because it would drastically increase the number of steps required to set up a new machine, and I thought it would be worth investigating whether I could using Nix to configure NeoVim entirely. I use quite a few different tools and so this became quite a complex process, but I’ve got something I’m pretty happy with and picking it all up on my work machine was a simple case of pulling my dotfiles repo[1] and running `nix-shell` — simply brilliant.
