Email is 50 years old

At some point this year, email turned 50 years old! In 1971, Ray Tomlinson sent the first email using the SNDMSG program on ARPANET.

50 Years of Email

But if the history of email tells us anything, it’s that email isn’t going away any time soon

Email is 50 years old, and still where it’s @

    The du command for #Unix was written on November 3, 1971. It is 50 years ago. Almost as old as me lmao. Happy birthday du command. I like duf more but some prefer to use the ncdu on #Linux What do you prefer to use on your Unix/macOS/Linux system?

    50 years since the release of the Intel 4004 microprocessor!

    The Chip That Changed the World
    Most of the wealth created since 1971 is a result of Intel’s 4004 microprocessor.

    The world changed on Nov. 15, 1971, and hardly anyone noticed. It is the 50th anniversary of the launch of the Intel 4004 microprocessor, a computer carved onto silicon, an element as plentiful on earth as sand on a beach. Microprocessors unchained computers from air-conditioned rooms and freed computing power to go wherever it is needed most. Life has improved exponentially since.

    Back then, IBM mainframes were kept in sealed rooms and were so expensive companies used argon gas instead of water to put out computer-room fires. Workers were told to evacuate on short notice, before the gas would suffocate them.

    The Microprocessor at 50: How the 4004 Changed The World

    The first general-purpose processor of the modern age came off the line today in 1971 to power a calculator. It changed the world.

    Intelin 4004 täytti 50 vuotta

    Intelin ensimmäinen kaupallinen mikroprosessori oli kuuluisa 4004. Se julkistettiin 15. marraskuuta 1971 eli prosessori on tullut kunniakkaaseen 50 vuoden ikään. 4-bittinen suoritin koostui 2003 transistorista. Itse suoritin vei piillä tilaa 14 neliömilliä. Kellotaajuus oli 760 kilohertsiä.

    4004-prosessorin piti olla Buscomin taskulaskimen uusi suoritin.

    Monen mielestä 4004 aloitti nykyaikaisen elektroniikan aikakauden, mutta todellinen murros tuli vasta hieman myöhemmin, vuonna 1974 julkistetun 8-bittisen 8080-piirin myötä. Siinä osoiteväylä oli levenntty 16-bittiseksi ja dataväylä 8-bittiseksi, ja kokonaisuus paketoitiin 40-nastaiseen DIP-koteloon.

    Intel Marks 50th Anniversary of the Intel 4004
    The historical milestone marks the arrival of the first commercially available microprocessor, which would shape life-changing technology.

    What’s New: Today, Intel celebrates the 50th anniversary of the Intel® 4004, the world’s first commercially available microprocessor. With its launch in November 1971, the 4004 paved the path for modern microprocessor computing – the “brains” that make possible nearly every modern technology, from the cloud to the edge. Microprocessors enable the convergence of the technology superpowers – ubiquitous computing, pervasive connectivity, cloud-to-edge infrastructure and artificial intelligence – and create a pace of innovation that is moving faster today than ever.

    “This year marks the 50th anniversary of the 4004 chip. Think of how much we’ve accomplished in the past half-century. This is a sacred moment for technology. This is what made computing really take off!”
    –Pat Gelsinger, Intel CEO
