I feel I am more fortunate than an average person to find issues and bugs in IT systems. Basically whatever I touch, there are problems. Some fairly benign like the United Airlines app losing all my flights (the flights could be accessed through a desktop browser via booking codes stored in email confirmations). And some looking more serious. On the lost flights the comment I got from one of my colleagues was "what do you expect - it is AI vibe coding". Fair enough. Release cycles spinning faster (that is what everybody wants: faster, faster, faster, right?). AI tools enabling this spin acceleration, but then the automated CI / test systems not coping with the changes. Code review also done by AI. And the result is the code spinning (pun intended) out of control of protein / carbon - based engineers. Apps get released, more features faster, KPIs improved. Users find bugs, but have no one to report them to, other than AI-based automated support systems. The bugs get eventually...

As a follow up to the last week's story about car dashboards - an addendum from my rental experience. It was a 2-day trip to Germany. My company has a rental agreement with SIXT, with some preferential rebates and integrated invoicing, so I went there without thinking too much. I liked SIXT in the past for their quite seamless "skip the line" online check-in (scan the driver's license and an ID, get a code to open a lockbox with the car keys). And it went OK like that this time too. But there were several things that were not OK.  During the booking process I got a number of really silly-looking options. Like "get Bluetooth for 5 EUR/day". And then "get Apple CarPlay" for additional 5 EUR/day. CarPlay requires Bluetooth so technically selecting it should select the Bluetooth option too... "Get parking sensors for 5 EUR/day".... the list was long. SIXT are you serious? There is no way to enable / disable these options remotely (or maybe th...

Cars peaked around 2005. This is the model year of my Subaru Forester STI (SG9). The best and coolest car ever made. 350 hp,  1500 kg (3300 lbs), frameless side windows, ultimate performance (including offroad), driver-focused interior, sub-5s 0-100km/h acceleration, unbelievable handling. The dashboard is driver-focused too with clean instruments panel featuring central tachometer and all distractors moved away. The other controls are just three well know knobs for ventilation (fan direction, fan speed, temperature). Then I have a 2-din aftermarket radio unit with capacitive touch and wireless Android Auto and Apple CarPlay . It also has tons of other functions including a CD/DVD player but I don't use them. Android Auto / Apple CarPlay is all that is needed these days. OK maybe an FM receiver for some old schoolers. As I travel a lot, I drive many rental cars too. The problem they all indicate is the car industry got drunk with semi/automated driver assistance subsystems and comp...

Evolution and its time scale are fascinating. It is however hard to imagine the universe and put it the into perspective. We are too busy with everyday duties. But once in a while when I have enough time to just stop, do nothing, and let my thoughts wonder and imagine... some things fall into place. I've been reading The Anthropic Cosmological Principle by John D. Barrow and Frank J. Tipler. It's been slow as I don't have it in an electronic form (nor as an audio book) and I don't bring it on my frequent trips. But maybe slow is good in this case as the book is very thought provoking. And it helps put things into perspective. The key take away so far has been the 10 billion years period. This is what it seems to take for the universe to create life. From simple atoms to birth of stars to death of stars and supernovae (they are necessary in the process as some heavy elements can only be created through supernova explosions). Then through seeding newly born planets with ...

I've had a number of very interesting (private) discussions following the last week's post on The Wall Of Money . One important take away has been to also mention the shadow banking system as the key contributor to the wall of money. If traditional central bank money printing is the visible high tide, the shadow banking system is the massive underwater current that amplifies that tide. It plays an enormous, often hidden role in inflating and sustaining asset valuations. A fund can take $100 million in Treasury bonds, pledge them in and borrow $95 million in cash, and immediately use that cash to buy equities. The lender who took those Treasury bonds as collateral can turn around and use those same bonds to back a different loan for someone else. Rehypothecation - rinse and repeat. This generates an immense amount of purchasing power that flows directly into financial markets. But it is a liquidity mirage. [Traditional Central Bank] → Creates Visible Money Supply [Shadow Banking...

I'm in the middle of a yet another round-the-world trip. Started two weeks ago in Europe for the Milan Bluetooth Member Summit , followed by the ultra dense in meeting Guangzhou International Lighting Exhibition in China. Next week I'll have a number of customer meetings in the USA. Luckily there is a short weekend pause in between, which I decided to spend in the "TikTok city" of Chongqing. It is a 6-hour high speed rail ride from the coast (the CR400 "Fuxing" at 350 km/h ), which I spent almost entirely glued to the window, with my brain working in the background to aggregate and generalize the inrush of information of the past 14 days. One of the puzzles I was trying to solve was the explosive SpaceX IPO, which, on the surface, has never made any sense to me. Everything I know about SpaceX, plus what I read in the S-1 filling, is a pure fiction (with the exception to the Falcon rockets that represent the solid part of the business). That is on the surface...

No, I cannot tell the details. Development of Bluetooth ®  specifications is governed by the confidentiality rules. So the only way to learn more is to be a Bluetooth SIG member and join the Working Groups. As I write this, the June Members' Summit in Milan, Italy is getting to the end. The week has been really packed. And as I have been excited about the progress on many fronts since I joined the SIG in 2012 (and then started to lead the Mesh Working Group in 2015), the excitement this week has reached all time highs. These things are complex and may seem to move slowly for casual observers "when will Bluetooth finally do X,Y,Z?", I've been super happy with the progress. To be honest, the progress is the one thing, but entirely more important is the spectrum of opportunities and the roadmap ahead. For the last couple of years, in parallel to development of Mesh / NLC - specific features (like the HVAC Integration Profile) , we have been doing a lot of ground work on ...
