Filogelos – pozdně antická sbírka řeckých vtipů

Většinou nepůjde o kdovíjakou vtipnost. Někdy se zasmějeme aspoň tomu, čemu se tenkrát lidé smáli, jak už to u starých vtipů bývá. Něco je snad přece jenom nadčasové. A místo blondýn nebo policajtů jsou nejčastějším terčem scholastici, takže to je vlastně korektní a nepodvratné. http://www.osel.cz/13843-filogelos-pozdne-anticka-sbirka-reckych-vtipu.html

How to put down your phone in 2025

There are certain social media rules we can all agree on: Ghosting a conversation is impolite, and replying “k” to a text is the equivalent of a backhand slap (violent, wrong, and rude). But what about the rest of the rules? When can we really remind someone of our old Venmo request? What happens when someone tries to flirt with you on LinkedIn?

AI is helping students with disabilities. Schools worry about the risks

For Makenzie Gilkison, spelling is such a struggle that a word like rhinoceros might come out as “rineanswsaurs” or sarcastic as “srkastik.”

The 14-year-old from suburban Indianapolis can sound out words, but her dyslexia makes the process so draining that she often struggles with comprehension. “I just assumed I was stupid,” she recalled of her early grade school years.

YouTube has a new plan to combat clickbait

Thumbnails play the YouTube equivalent of a movie poster, aiming to draw your attention to click and watch when you have hundreds of videos clogging your recommended content. Most of us have been baited to click on a video thanks to a flashy title and enticing thumbnail, only to be disappointed when the actual content has nothing to do with what the headline promised. 

Using attention-grabbing (often misleading) thumbnails and titles has become a standard practice on YouTube. Howev

AI use cases are going to get even bigger in 2025

Over the past two years, generative AI has dominated tech conversations and media headlines. Tools like ChatGPT, Gemini, Midjourney, and Sora captured imaginations with their ability to create text, images, and videos, sparking both excitement and ethical debates.

However, artificial intelligence goes far beyond generative AI—which is just a subset of AI—and its associated models. AI’s real promise lies in its ability to address complex challenges across diverse industries, from mi

TikTok is full of bogus, potentially dangerous medical advice

45 years ago, the Walkman changed how we listen to music

Back in 1979, Sony cofounder Masaru Ibuka was looking for a way to listen to classical music on long-haul flights. In response, his company’s engineers dreamed up the Walkman, ordering 30,000 units for an initial production run. Forty-five years later, Sony has sold over 400 million Walkmans and incited a revolution in music technology. 

While there are still Walkmans for sale, most use iPhones and Androids to tune in nowadays. Sony Walkman sound engineer Sato Hiroaki, who joined t

Even as the latest phones and wearables tout speech recognition with unprecedented accuracy and spatial computing products flirt with replacing tablets and laptops, physical keyboards remain beloved for their efficiency.

The future belongs to systems of action

The world of enterprise tech is built on sturdy foundations. For decades, systems of record—the databases, customer relationship management (CRM), and enterprise resource planning (ERP) platforms we’re all intimately familiar with—have served as reliable pillars underpinning every major business. Vendors selling them have become household names and the technology is a core component of how enterprises operate, scale, and report. They’ve embedded themselves, seemingly immovably, into how the
