Shirish Agarwal: A tale of unfortunate coincidences and incidents

Filed under

Linux
Debian

I went back to the vendor with my old stock SMPS and it worked but found that grub2 menu was missing. It was just plain booting to windows 10. I started a thread at debian-user trying to figure out if there was some issue at my end, maybe some grub variable had got lost or something but the responses seemed to suggest that something else had happened. I also read through some of the UEFI documentation on wikipedia and web, I didn’t go to much depth as that would have been distracting as the specification itself is evolving and is subject to change. I did find some interesting bits and pieces but that is for a later date perhaps. One of the things I remembered from my previous run-ins with grub2 issues is that supergrub2 had been immensely useful. Sadly though, the version which I tried as stable was dumping me to grub rescue instead of the grub menu when I used the ISO image on a thumb drive. I could have tried to make a go for it but was too lazy. On an off-chance I looked at supergrub2 support and did find that somebody else also have had the same exact issue and it was reported. I chimed in and tried one of the beta versions and it worked which made me breathe easier. After getting into debian, I tried the old $ sudo update-grub which usually fixed the issues. I again tried to boot without using the help of the usb disk but failed as it again booted me into MS-Windows environment.

GNU/Linux on Tablets: Ntablet and Beyond

  • Ntablet Linux commercial open-source tablet from $225

    The Ntablet open source tablet has been created to provide developers, enthusiasts and hobbyists with a programmable learning platform offering an all in one device for creative projects. Watch the demonstration video below to learn more about the world’s first commercial open source tablet. Launched via Kickstarter this week and is now available with earlybird pledges from $225 or roughly £176, offering a 50% discount off the recommended retail price. Full goes to plan worldwide shipping of the open source tablet is expected to take place during March 2020 “As a portable tool, it gives not only convenience to your projects, but also help to create more innovative designs as what you imagine. With it, you can start programming and developing anywhere, you can freely DIY and control TV, air conditioner, curtain, light, and even Robot. Ntablet is also a Linux based tablet, the inside core-board and motherboard are connected in the way of the socket, which enables users to change the core-board anytime, to run different operating systems or applications, like Android and Linux. 20 pins and 4 pins sockets are designed on the motherboard, to be used to connect with GPIO board, users can do kinds of debug or control after connection.”

  • FieldKit Is The Grand Prize Winner Of The 2019 Hackaday Prize

    While some are still waiting for the age of the Linux desktop, this project moves past that and achieves an open design for a Linux-based tablet. Goals of the project focus on sidestepping the OS lock-in present in many consumer tablets, and delivering a hardware design that is both repairable and upgradable — traits currently absent in all consumer tablets. Recognized for Best Design, this project is awarded a cash prize of $10,000.

3D Subscription software driving move to open source

3D software makers' move to subscription models is pushing people to use open-source software because users are fed up with the price and neurotic terms and conditions. For a while now professional 3D software like 3DMax, Maya, AutoCAD (Autodesk) and Substance Painter (Adobe) are only available on a monthly or yearly subscription basis which means that you cannot get your paws on a perpetual license for these industry-standard 3D tools anymore, cannot offline install or activate the tools, and the tools also phone home every few days over the internet to see whether you have "paid your rent". This means if you stop paying your "rent" the software shuts down, leaving you unable to even look at any 3D project files you may have created with software. But this has created so much frustration, concern and anxiety among 3D content creators that, increasingly, everybody is trying to replace their commercial 3D software with Open Source 3D tools.
