Fixing 'No space left on device' Error on an Old Dell's EFI Variables

2025-02-24

While migrating boot drives and setting up GRUB on an old (2011) Dell, the author encountered a 'Could not prepare boot variable: No space left on device' error. The `efivars` partition was full according to `df -h`, despite having only a few boot entries. Suspecting fragmented or unusable space in NVRAM, the author booted to an EFI shell and used `dmpstore` commands (`dmpstore -s efi-vars`, `dmpstore -d`, `dmpstore -l efi-vars`) to clean up EFI variables. This freed up space and resolved the issue. Caution: This process might brick your system; check `dmpstore`'s help before using these commands.

Retrofitting an M4 Mac Mini into an iMac G4: A Hackintosh Odyssey

2025-02-26

The author embarked on a project to integrate an M4 Mac Mini into a 17-inch iMac G4, creating a powerful retro-futuristic machine. Initially, a Juicy Crumb DockLite G4 was attempted but its color banding, low resolution, and lack of automatic screen shutoff proved problematic. The author ultimately replaced the screen with a high-resolution Sharp LQ170R1JX42 LCD and corresponding driver board. Custom 3D-printed and CNC-machined parts were created to manage cable routing and Mac Mini mounting. Challenges included backlight control and exposed ports, but the resulting 'iMac G4(K)' successfully runs, blending retro aesthetics with modern performance.

World's Second Worst Graphics Card: A TTL Gate Masterpiece?

Inspired by Ben Eater's 'world's worst video card', Leoneq built something even... worse? This text-mode graphics card, boasting a VGA resolution of 800x600@60Hz (accessible 400x300), uses only TTL gates and a surprisingly low 21 IC count. Featuring support for Latin, Polish, and even the Standard Galactic Alphabet, the card leverages EPROMs and SRAM for character storage. While plagued by glitches, noise sensitivity, and a generally unimpressive image, this project is a testament to resourcefulness and a humorous take on hardware limitations. It's a testament to the power of ingenuity even when facing a 'terrible idea'.

The British Navy's Secret Weapon: Institutional Design and Incentives

This article explores the institutional reasons behind the British Navy's exceptional combat effectiveness from the 17th to 19th centuries. It argues that superior technology wasn't the key, but rather a sophisticated system of incentives designed to prevent admirals from shirking combat. High salaries, a strict promotion system, unique battle tactics (like the line of battle and weather gauge), and harsh Articles of War (including the death penalty) ensured high combat motivation and accountability. The rise of steamships altered naval warfare, ultimately leading to reforms of these systems.

Exploiting a Google Account Recovery Flaw: Brute-forcing Phone Numbers with IPv6 and BotGuard Tokens

A security researcher discovered a vulnerability in Google's account recovery process, allowing attackers to brute-force phone numbers to gain access to user accounts. The vulnerability exploited the fact that the account recovery form still worked with JavaScript disabled, bypassing Google's rate limiting and CAPTCHAs using IPv6 IP rotation and BotGuard tokens. Attackers first obtain the target's name via Looker Studio, then use the password reset flow to get the phone number suffix. A custom program then uses proxies for brute-forcing, revealing the full phone number. Google has since patched the vulnerability.
