There are several things that give me goosebumps. Or make me think how little we comprehend / understand about the weird world we live in. Physics - the way we have it now - is completely bent. Totally far from being intuitive and understandable. Take the John Wheeler's double-slit experiment . A source of light and a screen with two thin, vertical slits. You shine the light through the slits, the light acts like a wave., interferes with itself, resulting in a ripple-like pattern on the wall. Turn the light down to only a single photon. The photon acts like a particle: hits the wall in one specific spot. But after enough photons arrive, the same interference pattern emerges. The single photon interferes with itself. Now add a detector to the slits, to figure out which slit the photon actually passed through. When you do this, you never get an interference pattern on the far wall. The OBSERVATION (not any interaction with) of the photons affected their behavior. Then there...

There are myriads of legal nonsense situations we encounter every day. Somehow the most often they are related to general information technology (IT). Definitely #1 are the EU cookie banners. David Heinemeier Hansson (DHH) - the creator of Ruby on Rails - has been perhaps more vocal about the EU Cookie Mandate (specifically cookie banners) than almost anybody else. He views them as a prime example of well-intentioned but fundamentally "stupid" and failed legislation. He points out that companies have spent billions of dollars on compliance, legal fees, and implementation, yet there has been no material improvement to user privacy. Most users simply click "Accept" to get the banner out of the way, effectively granting the very tracking permissions the law intended to curb. And the bureaucracy refuses to admit the solution didn't work. And #2 are variety of Terms of Use (ToU) that must be accepted to do something. For example, when you first pull the battery tab o...

I'm writing this post in December, 2025, in preparation for couple of weeks' holidays In January / February. I understand packrafting now may sound a bit extreme, but hey, it is peak summer now in New Zealand. And NZ is where it all started - I found this article (see the snapshot) in an old magazine that was left in one of the New Zealand's mountain huts. That was in 2024 - almost two years ago. Since then we have completed a white water packrafting camp to get familiar with packrafts and river rafting / kayaking in general. That was in Slovenia, and is a great idea for an active summer adventure in Europe. Then we found a great supplier of packrafting gear in Poland - I mentioned packraft.pl in my Spring'2025 post on the subject. Now we are back to where it all began. Not as ambitious as Mitchell Radford, but his documentary is definitely a good one to understand what this activity is all about.  We're also trying to pack much lighter than he did. 39 kg / 85 lbs...

2025 was very travel - intensive for me. Needless to say I managed to ern the 1K status flying only in (often deeply discounted) economy class.  This can be nicely seen in the Flighty app . The app that I called useless (because all it offers is already possible in the native airline apps). But on the other hand Flighty is really pretty and the visualization of flights overlayed on top of Apple Maps is cool :) Travel is the inherent part of my job and I do it by choice. Honestly speaking I do not understand many people that I meet who "feel for me" and do not like to travel at all. Yet they still either do international business or actively participate in global standardization efforts through different standards committee memberships. My response in such case is almost always in the lines of "have you been sentenced to do this job?", which of course may be rude, but ultimately I believe that everyone is the architect of their own fate. And in most fee / democratic ...

I'm about to leave for a 4-week mostly off-grid holidays. This takes some preparation: planning places to visit, updating topographic maps, completing the gear. At the same time I've been preparing my online / electronic side of things for the prolonged absence. This basically includes two things: 1. Minimizing the stuff that will bloat my inboxes. Mostly to avoid the post-absence trauma of dealing with hundreds (if not thousands) of different kinds of notifications and messages. These days just about everything wants keep you "up to date", and this is an enormous trap. The mails and notifications are mostly useless, outdated or conflicting. And they contribute to 90% (or more) of messages you get. So very patiently I have been removing myself from any distribution lists and subscriptions. That has worked, as over the recent days I have been receiving significantly less traffic. Calming and liberating this feels. 2. Making sure the phone battery lasts as long as possi...

Another year behind us - time flies. Steps - wise I more or less matched the 2024 numbers, which I called "definitely below expectations". Now the expectations were trimmed and I am quite happy with the outcome. Yes, lowering expectations is the easiest path to happiness! The knee and ankle injuries took longer to heal than I expected and affected my walking distances at the beginning of the year. 2025 was also very travel - intensive (if not the most!). And especially considering the long distance nature of my business trips, I am quite happy with the amount of physical exercise I was able to put. This physical exercise is BTW the best way to fight jetlag and quickly accommodate to new time zones. So no real downs in 2025 and my total is now about a half of the Earth's circumference: 19667 kilometers (with the watch on). Some TZ changes were quite brutal. In late August I flew from Poland to California (9 hours shift) for the 3-day IES Annual Conference and then overnigh...

It took me several more days to complete the move to the new iPhone. Generally speaking this is a fail of the industry. But on the other hand I understand why certain things are difficult. But still - stepping up just two generations of hardware (from 15 to 17) withing a single ecosystem (Apple) should not be that complicated. Especially as they have not just the operating system but the entire apps ecosystem under control. And people are pushed to pay monthly recurring service fee (iCloud) on the promise to have things taken care of. The Revolut eSIM did not migrate. This was kind of expected (I have no idea if other eSIMs can be migrated, but anticipating that I waited with the migration until returning from my final 2025 international trip). On the other hand Apple itself pushes the developments to get rid of physical SIM cards entirely (iPads do not have SIM slots since 2024). So once Apple gets rid of the physical SIM slot in iPhones, I'm not sure what we are supposed to be d...
