Palm Pilot was my first touch screen device. 25 years ago, it was revolutionary. It turns out Palm still lives today, in a form of a tiny Android phone - the Palm Phone. This device is useless as a primary phone, as Palm went a bridge too far squeezing the battery such that it lasts half a day on light use. But with volume and weight of 25% of a typical 2021 phone, it is great for casual use. It runs proper Android and just about any app you may want. And Palm did really a good job customizing the UI to fit the small screen - the launcher is first class. It can be a backup on the road. Broken screens happen. and this thing is so tiny it is no brainer to carry it as a backup device when traveling. It is a great "fitness" phone, if you need one. Again the tiny nature helps with any activity and it is waterproof. There is even a specially designed custom armband which puts the on the forearm - easy to navigate things like music or calls. For me it is primarily an audiobooks-on-t...

Electric cars are surely the future, but most brands have been offering just faster horses. From Teslas to Volkswagens it has been a yawn... Better 0-60, more touch screens. No qualitative change. And that is precisely why I'm so excited by Stellantis'  Citroën AMI . What a great car! I own two vehicles. One is a special version of 2005 Subaru Forester STI . Probably the most fantastic car ever built by Subaru. My other one is the Boosted Rev - an electric scooter. Probably, again, the best electric scooter ever built. Unfortunately also the one that brought the company which created it to bankruptcy. The STI and the Rev have many things in common - they both are sleepers. Phenomenal performance and handling in ordinary looks. I use the Rev almost everyday from April till October. It is great on warm sunny days. Not that great when the weather is cold. And terrible when it rains. And this is when I switch to the STI. But driving a performance car on crowded city streets is an ...

On the positive side Apple AirTags are great. Tiny, long lasting, ultra-wideband enabled (to enable directional indicators when locating a lost one). And of course, the key advantage of this system is the crowdsourced network of billions of iPhones globally, which can help reporting a lost device. And on the surface the system is designed to protect privacy. But not all that glitters is gold. Let's scratch that surface a bit. While AirTags are designed to protect the owner, they do not protect against malicious owners. The simplest use case is that I buy an AirTag and drop it in a pocket of a person I want to track. Instantly I have that person pinpointed on a map, in real time. A stalker's dream. Technically if that person happens to have an iPhone, it will eventually start alerting about a "foreign" tracking device she carries, but that is only on an iOS device. Non-iOS users are in the cold. Secondly, AirTags internally do not implement a secure environment and th...

It was December 2016 and we were entering the last straight to finalizing the Bluetooth Mesh specifications . I felt we were missing the crucial part of the architecture though, We had lights and sensors and other stuff specified. All good. The lights could react to on.off, dim level, color temperature and hue / saturation. And I was especially happy about how we defined sensors, reusing the wealth of data already defined by Bluetooth such as (GATT) Units - things like Celsius temperature or catalytic activity concentration (katal per cubic metre), and GATT Characteristics, giving us instantly definitions of close to 200 sensor types .  But lights and sensors had been in separate domains. Sensors could report occupancy and (too) low light level, while lights would still remain off, waiting for an "on" or "dim up" message to arrive. This is how everybody else have been doing things, from Z-Wave to ZigBee and DALI. There the protocol defined and messages within that p...

I blogged twice on Theranos in 2019. Actually the second post was bringing back the most profound statement by Steve Jobs about the " tremendous amount of craftsmanship between a great idea and a great product ". One would think the Bad Blood lesson was sufficient to stop lunatic CEOs from pitching sam stories and lemming investors from following them blindly. Apparently, not. In a remarkable public statement last week Tesla published on their FSD system, saying " ...there is no guarantee.... (the FSD) ...will perform as expected... (...) ...or at all. ". On the other hand they argued the AutoPilot was not engaged in the recent Texas crash and there was a driver at the wheel. At the same time the official Tesla Self-Driving Demonstration video  still starts by saying "The person in the driver's seat is only there for legal reasons. He is not doing anything. The car is driving itself.".  How does it all add up? If you're interested in the technic...
