Today marks the Summer Solstice, the longest day and shortest night of the year in the Northern Hemisphere. โ๏ธ๐
This astronomical event occurs when Earth's axis is tilted most directly toward the Sun, allowing regions in the Northern Hemisphere to receive the maximum amount of daylight. It's also considered the official start of summer in many parts of the world.
From tomorrow onwards, daylight hours will gradually begin to decrease until the Winter Solstice arrives in December. ๐โจ

One man drew the first 176. By hand. In 1999. ๐คฏ
Meet Shigetaka Kurita ๐ฏ๐ต
> Japan, 1999. Phones just went online. Texting was still brutal.
> Just 250 characters per message.
> Not enough room for a single real feeling.
> His fix: trade words for tiny pictures.
> His canvas: 12x12 pixels. 144 dots total.
> 176 icons. Hand-drawn. Faces, weather, food, hearts.
> Total size: 3 kilobytes. Smaller than one photo on your phone.
> Japan falls in love. Fast.
> 2010: Unicode standardizes emoji. Every phone on Earth follows.

Absolute legend ๐
The NSA spent billions trying to break encryption.
One German programmer beat them.
He earned only $25k a year. ๐คฏ
Meet Werner Koch ๐ฉ๐ช
> German free software developer. Born 1961 in Dรผsseldorf.
> 1997 ~ Richard Stallman called for a free encryption tool.
> Only option then: closed-source, US-restricted PGP.
> Werner answered. He built GnuPG (GPG) alone ~ free software to encrypt files, sign software, and verify identity.
> 1999 ~ Released GPG 1.0. Fully open source. No restrictions.
> Today his code verifies every Linux server update, every Debian package, every Tor Browser download on this Earth.
> Every signed Linux release depends on it.
> Used by activists, dissidents, and security pros worldwide to stay untracked.
> Edward Snowden used GPG in 2013 to leak NSA documents. It held up against the worldโs most powerful spy agency. ๐
> 2001 ~ Founded g10code with his brother to work full-time on GPG.
> Earned only $25,000/year for 14 years while supporting his wife and daughter.
> 2012 ~ Funding ended. He had to let go of his only programmer.
> 2013 ~ He was the sole maintainer and nearly quit.
> 2015 ~ ProPublica story dropped. Internet donated $137k in 24 hours.
> Facebook + Stripe pledged $50k/year each. Linux Foundation gave $60k
> Won FSF Award for the Advancement of Free Software.
> Today he still maintains GPG from home in Erkrath, Germany.
This one man kept the internetโs secrets, secret.
The world almost lost him in 2013.
His code still protects yours.
