Caveat emptor is undefeated in online shopping
Life, James Hein, Published on 11/03/2026
» It is becoming more common to buy things online. The majority of my shopping, not counting groceries, is now done that way. In the past I've warned about prices that are too good to be true, like a 4TB thumb drive for a few dollars from sites like Temu and AliExpress. There is now a kind of middle ground where the price could be correct and it's coming from, say, Amazon. Recently, even though I had some doubts, I bought a 5TB SSD drive from Amazon for around half of what I'd expect it to be. I did this knowing I can easily send things back to Amazon.
Those pesky pixel trackers

» I've written about the tracking in TikTok. I recently found out you don't need to have the app installed to be providing tracking data to this platform. The term you need to learn today is "tracking pixel".
Samsung's future flex

» So whatever happened to the rollable displays we were promised some time back? Turns out companies like Samsung have been working on them, presenting a few at the recent Society for Information Display (SID) annual exhibition. The key to this technology is the OLED (organic light-emitting diode) display because it doesn't need a backlight. This allows for paper thin, flexible displays. In keeping with their usual nomenclature, Samsung calls their first device the S-foldable. Their range starts at phone size and unfolds twice to a 7.2-inch screen. They also presented a slidable screen that pulls out to give a wider view. Then came the 17-inch foldable screen that starts as a tablet that can be used as a small monitor tagged as the "Carrying Small Seeing Big". For now, these are concept devices that we should see in the wild next year. Not to be outdone, LG demoed a 65-inch rollable OLED TV along with a 12.8-inch rollable device. China is also in the mix with Visionox showing their rollable OLEDs.
None more black

» Accidental discoveries have been responsible for many useful items like rubber and penicillin. A couple of science types at MIT in the US wanted to see if they could grow carbon nanotubes on aluminium to increase its conductance properties. Instead they found they had made the blackest substance yet known to man. It absorbs 99.96% of the light from any angle making it 10 times blacker than the current options. Potential uses include telescopes, optical blinders and art. Carbon nanotubes, is there anything they can't do, eventually?
