🚀 From Punch Cards to AI: The Evolution of Code 💻 Ever wonder how we got from Ada Lovelace’s first algorithm in 1843 to the modern languages powering today's AI? Look at how the foundations laid by pioneers like Grace Hopper (COBOL) and Dennis Ritchie (C) paved the way for JavaScript, Python, Rust, and the tech we rely on every single day. What was the very first programming language you learned?

@sysxplore RAID-1. is reliable & most inexpensive from other raid types. Simple in concept. RAID-3/4. I was always wondered what will happen if Disk-4 fails. RAID-5. :-| RAID-6. Looks very attractive, but I haven't tied it yet RAID-10. was excellent in the era of HDD dominance, before SSDs.

Jour 065, orbite 1005 – La science du dimanche matin avec Sophie, épisode 4 : Eau, bulles d’air et force centrifuge. Remarque importante: à bord de la Station, nous avons chacun une gourde souple que nous remplissons avec de l’eau recyclée. Cette bouteille en plastique est un accessoire utilisé uniquement pour des démonstrations scientifiques ludiques ! 🎥 @esa/ @NASA #εpsilon • • @esaspaceflight@ESA_fr@Space_Station@CNES@NASA_Johnson

Park adventures with my six-year-old on a beautiful sunny day. Proof that playgrounds are still fun, no matter your age! Reminds me we are all born joyful (and maybe just a bit silly)! 🎥 Camera skills by my little one! #BigKid #BeYou

Easter in Greece 🇬🇷 Explore Greece: tasteatlas.com/greece Greek Easter is not a quiet holiday. It is built entirely on wood smoke, heavy butchery, and open fire. Long metal spits loaded with large cuts of meat and thick rolls of kokoretsi turn slowly over glowing coals. The intense heat forces the fat to render, blistering the exterior into a hard, charred crust. Tables are quickly loaded with heavy platters of roughly chopped roast, thick fried potatoes, and dense scoops of tzatziki, washed down with continuous pours of cold white wine. Before the eating begins, hard-boiled eggs dyed a deep, dark red turn the table into a physical battleground. Gripping the egg tightly to expose just the pointed tip, you drive it directly into your opponent’s egg. The goal is pure blunt force. You want to shatter their shell completely while keeping yours perfectly intact, leaving the cracked ones to be peeled. The loud celebration extends into the night around massive, roaring street bonfires. Even the religious traditions leave a physical, charred mark. The holy flame is carried home, and the burning candle is used to scorch a black cross of soot directly into the wall above the front door. Credits: @helena_marieee

@JennaWDavis @engineers_feed Is this a progress in human space exploration? I would expect a more refined entrance for the astronauts after decades of experience. Space-shuttle was a major forward step. But after its termination, we chose to go back to older methods, instead of evolve it and move forward

The term “dark side of the Moon” is one of those persistent misnomers: nothing on the Moon is permanently dark. The hemisphere we don’t see from Earth, the far side, receives sunlight just as regularly as the near side, with roughly two weeks of daylight followed by two weeks of night at any given location. The reason we never see that far side is not about lighting, but dynamics. The Moon is tidally locked to Earth, which means its rotational period and orbital period are the same. In practical terms, it rotates exactly once on its axis in the same time it takes to orbit Earth once, so the same hemisphere always faces us. It’s not perfectly fixed, libration lets us glimpse about 18% beyond the edge over time, but the bulk of the far side remains permanently out of direct view. Geologically, the far side really is a different world. It is much more heavily cratered and has far fewer maria, the large, dark basaltic plains formed by ancient volcanic eruptions. On the near side, those maria cover about a third of the surface; on the far side, barely about 1%. The underlying reason is still an active research topic, but the dominant explanation involves asymmetries in crust thickness and heat-producing elements early in lunar history. The near side had conditions that favored widespread basalt flooding, while the far side remained more rigid and preserved its impact scars. That’s why, visually, the far side looks brighter, rougher, and more “primordial.” For decades, this hemisphere was effectively invisible to human eyes. Even during the Apollo missions, astronauts only saw it briefly and under limited lighting conditions. That has just changed in a meaningful way with the Artemis II mission. Now, for the first time since Apollo, humans traveled back to lunar distance and executed a flyby that carried them around the far side. During that phase, the Moon physically blocked all radio communication, producing a ~40-minute blackout, an immediate, practical demonstration of what “far side” really means. While behind the Moon, the crew observed terrain that is rarely described from direct human perception: a landscape dominated by dense cratering, subtle color variations, and large basins like Orientale. They were also farther from Earth than any humans in history, following a free-return trajectory that loops around the Moon and naturally brings the spacecraft back home. When they emerged from behind the Moon, they witnessed Earthrise, one of those moments that tends to reframe the entire Earth–Moon system in a single image. So the “dark side” is not dark, and not mysterious in the literal sense anymore, but it remains scientifically distinct and observationally special. It is the hemisphere shaped by a different thermal and geological history, hidden from Earth not by shadow but by orbital mechanics, and now, thanks to missions like #Artemis II, finally being seen again not just by instruments, but directly by human eyes. © @NASA Lunar Reconnaissance Orbiter (November 2009 & February 2011)

@NASA Awesome Earth view ! Our "pale blue dot", looks absolutely fantastic !! I understand that behind these photos, there are the endless and tremendous efforts of decades, to see what is out there and to "boldly go where no one has gone before" ! Thank you NASA ! 🖖

Long before silicon chips, ancient Greeks built a complex device now known as the Antikythera mechanism. This corroded bronze relic, discovered in a shipwreck in 1901, is considered the world's oldest analog computer. Dating back to between 205 and 87 BC, it used a sophisticated system of at least 30 bronze gears to track the cycles of the Sun, Moon, and planets, and was even able to predict solar and lunar eclipses. Its complexity wouldn't be seen again for another thousand years.
