If you want to learn electronics without burning a capacitor or two, have a look at https://www.circuitlab.com/ . It allows one to draw circuit diagram and simulate it. Hope you'll find it useful.
Plan 9 is an Operating System (OS) from Bell Labs which is a successor to UNIX. It builds on the learnings from the previous Operating systems. Network computing and graphics is an integral part of the OS rather than an afterthought. It is modular and portable - it comes with a cross compiler . It is available, under MIT License , which anybody can use, learn and tweak. Features Everything is a file. Small Kernel: Around 5MB size which can be built in under 2 minutes. Singular Grid: All the computers running Plan 9 OS and connected together act like a singular grid. So there's no need for remote access solutions like VNC or RDP. This cool video shows a small glimpse of the possibilities. Process Isolation: Processes run within their own namespaces and are isolated from each other. So you can run rio (the window manager) within rio. Applications like Browsers don't need complicated sandboxing. And a crashing program is unlikely to bring down the OS. No DLL Hell : ...
UEFI ( Unified Extensible Firmware Interface) provides a quick way to set up a Plan 9 terminal on modern hardware . EFI System Partition (ESP) is a FAT32 partition. You should be able to modify it in most of the operating systems. Run mk in /sys/src/boot/efi . aux/aout2efi converts an a.out file to an EFI executable. For x86_64 hardware, copy over the files bootx64.efi (EFI application) , 9pc64 (kernel) , plan9.ini (configuration file) to \EFI\plan9\ directory in the ESP. If you want it be the default OS , you can create a symlink \EFI\boot to \EFI\plan9. Remember to include the full path to the kernel in plan9.ini. ( Note: ESP is a FAT32 partition. Hence you must use backward slashes.) bootfile=\EFI\plan9\9pc64 When bootx64.efi fails to find the bootfile (e.g. kernel is missing, plan9.ini is missing or path is incorrect), you can provide the arguments at > prompt followed by a boot command . Y...
Render Dynamic HTML using plot and qjs. Render a simple website Font zoom E-Book Reader eBook is a collection of HTML files in a ZIP archive. Follow same steps for Comic Book reader which are collection of JPG/PNG images in a ZIP/RAR archive. For columns, pure HTML solution involves column-count CSS property. However, this works only for designed screen sizes. For non-standard sizes, the first column might span multiple pages before continuing in the second column. Hence, the page mode manages the split without relying on the column-count. Keymap t Table of Content -/= Font zoom 1,2,3 Column s Toggle scroll/page mode ...
