Went to Kenmore Camera this morning to handle some of the compact APS-C cameras.
I handled a used Fuji X-E2 which is similar in size to the x100VI and enjoyed the feeling. I may need the thumb grip accessory.
The Nikon Z30 with the pancake zoom was tempting, but the AF system would take some getting used to.
The Sony a6700 just didn’t spark joy. It seemed very capable, like a technical tool.
I think I’m set on the X100VI.

Hey friends!
We are just back from another nice 42km #cycling loop. Lots of headwind, lots of up and down and a little mistake in starting the tour at the highest point of the loop. The final, long ascent was a bit... Not so much fun.
But the views were just ace, more streets than yesterday but very few traffic! I was rather happy to have sun cream today.
Just a great Sunday!

I've recently finished the book "Flying Blind: The 737 MAX Tragedy and the Fall of Boeing", and it was actually pretty depressing to read how a focus on pure "shareholder value" and private enrichment of executives can quickly destroy most of the value of one of the biggest and highly innovative companies. Reading about the destruction of technical excellence in favor of a race to the bottom for short term market gains should be a cautionary tale for all companies that are currently technical leaders. Learn from history how easily that can change.
PS: Now that I know more about the behind-the-scenes reasons for the 737 Max accidents and resulting deaths, I will personally avoid flying in any of them in particular, and generally try to stay away from Boing aircraft while the company is further slipping into even shoddier QA practices.

Selenskyj fordert nach Angriff mehr Unterstützung
Der ukrainische Präsident Wolodymyr Selenskyj hat nach dem russischen Raketenangriff auf die Stadt Tschernihiw mehr Entschlossenheit und Unterstützung der westlichen Partner gefordert. "Dies wäre nicht passiert, wenn die Ukraine ausreichend Luftabwehrausrüstung erhalten hätte und wenn die Welt entschlossen genug gewesen wäre, dem russischen Terror en…

Chernihiv. A rescue operation is underway following a Russian missile strike. There are people under the rubble. As of now, 20 people are reported to have been injured and ten killed. My condolences to their close ones. Unfortunately, the death toll may still rise. This would…

Study on ploughing phenomena in tool flank face workpiece interface including tool wear effect during ball end milling
Ploughing phenomena occurring during precise machining processes affect the formation of surface finish and progress of tool wear. Therefore, this study presents an evaluation of ploughing phenomenon by studying the ploughing forces in tool flank face workpiece interface during precise ball end milling of AISI L6 alloy steel. Developed original model of ploughing forces involved the effect of minimum uncut chip thickness hmin and ploughing volume during ball-end milling. Estimated ploughing for…

Two-stage growth for highly ordered epitaxial C$_{60}$ films on Au(111)
As an organic semiconductor and a prototypical acceptor molecule in organic photovoltaics, C$_{60}$ has broad relevance to the world of organic thin film electronics. Although highly uniform C$_{60}$ thin films are necessary to conduct spectroscopic analysis of the electronic structure of these C$_{60}$-based materials, reported C$_{60}$ films show a relatively low degree of order beyond a monolayer. Here, we develop a generalizable two-stage growth technique that consistently produces single-d…

Investigating model influence on the analytical resolution of neutron reflectometry

Investigating model influence on the analytical resolution of neutron reflectometry
Neutron reflectometry is a critical tool for investigating the structure of thin films and interfaces. However, the misapplication of the Born approximation to reflection geometry leads some to assume that the minimum thickness that may be probed by neutron reflectometry is limited by the Q-range of the measurement. In this study, we use model-dependent analysis, multiple isotopic contrasts, and magnetic spin states, to show that it is possible to resolve structures significantly smaller than t…
