Awesome VIM clutch. A hardware pedal for improved text editing in Vim

Posted on in Categories Link last updated April 22, 2017

That is right. I found a hardware pedal for improved text editing in Vim. This is a mind blowing hack for vim user.

VIM Clutch is a hardware pedal for improved text editing speed for users of the magnificent VIM text editor (1, 2). When the pedal is pressed down, the pedal types “i” causing VIM to go into Insert Mode. When released, it types and you are back in Normal Mode.

The final result:

The Librem 13 v1: A full-fledged modern laptop with coreboot for freedom and privacy freaks

Posted on in Categories Hardware last updated February 28, 2017

Coreboot is a free and open source software. The project aimed at replacing the proprietary BIOS firmware and blobs. Unfortunately, Coreboot does not run on the modern laptop (except Chromebooks) due to Intel ME and other closed source technologies.

Purism vendor sells Linux preloaded on the Librem 13 and the Librem 15 laptops. Purism claims to follow a strict belief in users’ rights to privacy, security, and freedom. Untile today Librem bios was not freed. However, the coreboot port for the Librem 13 v1 is 100% done. It means you can have blob free Coreboot running on a full-fledged modern laptop. The laptop comes with Hardware Kill Switches that physically sever the circuit at the hardware level for Wireless & Bluetooth, Camera & Microphone. The specs are as follows:

How to protects Linux and Unix machines from accidental shutdowns/reboots with molly-guard

Oops! I did it again. I thought I was logged into my home server. Turns out I rebooted the db server. Another my not so favorite is typing “shutdown -h 0” into the wrong terminal. I know a few people who have admitted to doing that here.

My anger that can't be contained
Is there any end to the madness? Do I need to suffer from accidentally random reboots and shutdowns? After all, it is human nature to make mistakes, but one should not keep on making the same mistakes again and again.
