Insta360 GO 3S has been a great evolution of the original Insta360 GO 2 camera. I was a big fan of the GO 2, as it was as close as possible to almost-invisible button-sized camera. The GO 2 had some drawbacks though. Image quality was good but not great and there were limited menu navigation options, as the "base station" had only a super tiny text display. But it still proved very useful. Even during the white water kayaking trip we took just two weeks ago. The "kayaking" included some related fun like jumping off a suspension bridge to a stream. But even without the cliff jumping, white water kayaking is a kind of activity when anything can happen. So carrying a phone is not the best idea. I know iPhones are waterproof now, but there are more dangers in white waters, in particular stones. Plus you must be prepared to lose all your gear. I would also not dare to jump off a cliff with an iPhone in my hand (I did that with the Insta GO). One other problem with a smar...

I blogged about eSIMs last year. Among all the features which make my phone great, this is the one of the most used. Mobile data abroad has always been an issue due to outrageous pricing plans. So travelers seek alternatives. Of course free WiFi here and there helps but it continues to be shaky and slow. And only available in more inhabited places. But move further into the wilderness and there is no WiFi. While mobile (mostly LTE and 5G) continues to be available. And speeds are decent (LTE) to great (5G). The problem with 5G is that you can easily transmit data at a rate of many dollars per second and also quickly exhaust the "global" allowance from your home carrier. My recent experience shows you should plan for 1GB per day for moderate use (uploading photos, checking maps etc) to multiple of that if you want to upload trip videos. The solution of course was to swap SIM cards to a local prepaid plan, but that required physical shopping. Now with eSIMs the local data rate...

This post is way overdue. But it is only now that the new Bluetooth® audio technology - the LE Audio is finding its way into products. It has been 10 years in the making. Internally LE Audio is super complex as it aims to propel wireless audio for the next 20 years (or more). My personal picks (in no particular order) of the features enabled by LE Audio are:  It uses the underlying Bluetooth Low Energy (LE) transport. Which not only means longer lasting earbuds, but most importantly Bluetooth-enabled hearing aid devices. It also means better behavior at higher packet loss - (longer range and dense/interfered environments). It introduces the new LC3 audio CODEC, which offers better perceived audio quality at half the data rate (compared to the old Bluetooth SBC) AND an order of magnitude better latency (down to 20-30ms range). Think about the impact of that on teleconferencing (and gaming of course). It natively supports multiple audio streams, so joint / shared experiences are now...

The (very) traditional capitalism was strongly relying on savings as a foundation for the investment capital. The investment capital in turn was essential to keep the economy wheels spinning, as most of the industries were capital-intensive. From mining to manufacturing to distribution. The reliance of savings also was justifying the large spread in wealth, as it was the savings of the wealthy providing the investment capital. This model started breaking up roughly after the WWII and does not hold anymore. The majority of the capital needed today is the human capital. The fact there are many wealthy families in a country does not translate into the country's growth potential, if the middle class does not get broad access to proper education. And proper these days is not just high school. Honestly to be really prepared to contribute (and compete) a college or (better) a university is necessary.  The problem with human capital (which the worlds' economies have become so dependent...
