ICC (cricket) T20 World Cup - 20 international teams in the shortest, & big hitting format of the game.
The latest round of the oldest international rivalry in sport opens this tournament being held in North America. Canada beat the USA in cricket in 1844. Can they do it again?https://www.icc-cricket.com/tournaments/t20cricketworldcup/matches

For health generally, look here to find the original research on what is currently known on pretty much anything. Review articles will distill the individual publications. What is the "current" state of knowledge is not fixed, but changes over time because ideas continue to be tested and refined, and are understood to be incomplete.
The process of academic medical publication is far from perfect. Multiple journals exist with minimal peer review, and authors can pay to get their article published. Scientific fraud is a real problem and while efforts and techniques to detect it have increased, fraud will get through. The concept of conflict of interest is well understood, and any research sponsored or funded primarily by a drug or medical equipment company is viewed with an extra serving of suspicion. Compensating for placebo effects, and the variation in patients, and fluctuations in disease are also factored in. Statistical methods can be abused. A single publication suggesting a radical new idea is not proof. Truth does not reside in the source of the information. A true result, a result rooted in reality, is reproducible by others.
Hence review articles and meta-analyses summarising the research in an area, published in places that have a long history of academic rigour e.g. New England Journal of Medicine as just one example of many, and organisations like the CDC which monitor ongoing research across medicine and update their advisories over time are the public's most reliable sources of the best available information. These may be a few years behind the leading edge research but what they record has generally been peer reviewed and reproduced.
Anecdotes from individuals may lead to new research questions. Anecdotes from individuals may or may not be reproducible. An amusing example is the story of the Welsh miners with lung disease who were trialling a new drug to improve the blood flow through their lungs. A single miner told a female research assistant about a side effect and the result was eventually Viagra. Not going to ask how many of my readers can vouch for the reproducibility of that result!

Saw the name Tucker Carlson (trying real hard not to misspell that first name) in the link and don't even want to click that with a 10 foot pole. Anybody got a synopsis?
Tucker gives oxygen to a theory that tick borne diseases came from leaks from USA government bioweapons labs, according to the blurb on the linked page.

A slightly more reputable source of information.

I saw the aurora for the first time in my life last night. The solar storm activity has been the strongest in the last 20+ years in the last 24 hours. If you are at latitude 40+ degrees and have clear skies tonight you are likely to be able to see it with just your eyes.
I shot some photos using a tripod, wide angle lens, manual focus at infinity, ISO 200-400, f3.5, exposures between 5-10 seconds. Processed in post in Darktable to bring up the colours to a nice balance and dim the lights of Penzance in Cornwall (UK).

@Snowboarder123 Thanks for the photos.
The front slot/screw is going to move only when the board bends relative to the bow at the front of the board.
What is the material on the undersurface of the bow? And on the top of the board where the bow slides back and forth on the board top? Are the screws threaded for the whole length, or are they smooth where they rub against the slots? The slots look like a steel insert, is that correct?
How many days riding has it had, and are there any signs of wear on the slots/screws/board surfaces? Any instructions about disassembly and cleaning?
My comment about a pool noodle was tongue in cheek. I suspect the makers are trying to tell us that the interface between board and bow can accommodate board flex in a turn far beyond that which any reasonable rider could produce.

@barryj Thanks. That photo very clearly shows the difference between the front and the rear screw/slot configuration.
Front: 1 fixed screw each side, the other able to slide a little.
Rear: All 4 screws able to slide.

What I have been able to see and read so far seems like a variant on a sliding axle isolation plate, with a number of distinguishing features.
a) attachment/load bearing points at the ends of the plate, and significantly nearer the ends of the effective edge than many plate designs. AllFlex is probably the nearest in this regard.
b) no hinges, just a slide at the rear end (from the website description). The slide made up of 4 countersink screws in slots in the plate. I've not seen images of the non-sliding end. Exactly how the bend of the board under load is dealt with is not clear. How that interface holds up in actual use from wear and tear on the small areas of contact on the sides of the screws is of interest.
c) it's not clear what the actual bearing surface between plate and board consists of, nor how the friction under loading is minimised.
d) the plate appears to be a cambered "bow" (archery) like structure, designed to absorb and rebound the forces the rider generates as they make a carved turn. Control of board torsion seems to be a lesser priority. That absorb/rebound feature might help absorb forces from landing after aerial manoevures.

they state the set-up will allow board can be bent up to 45 degrees along its longitudinal axis.
Whatever that means! If you believe all the verbose obfuscatory waffle on the website, you'll believe anything.
A diagram which showed how much flex they meant by "45 degrees" would be far preferable. It might just mean they have a pool noodle for a board under the plate.
I much prefer to see the mechanism with my own eyes, and to hear/read the reports of riders who are NOT paid to gush about a products performance.

@Snowboarder123 Are you able to load some photos of the plate and the attachment points and talk about how the plate undersurface slides on the top of the board. There are pretty limited photos available on the Net.
Looks like the rebound out of the turn comes from the plate, not the board so much, while the plate places the effective rider mass a long way towards the ends of the board, rather than at the normal stance points.

Yodobashi Camera was kind of like that for photography. B&H NYC is pretty good, but not very close.
Dumb question.. so why is it that Japan / Korea are more carve oriented?Think of how much of Japanese culture is focused on the aesthetics, the beauty, of the activity. Archery, origami, flower arrangement, formal gardens with raked gravel, food presentation, calligraphy, the list just goes on and on.

Found this CSIA doc that briefly describes and illustrates the interaction between SCR & flex in a carved turn.
Look at pages 16-17.https://csia.snowpro.com/ServicesServlet/telechargement/document/Performance_Model.pdf

@Board Doctor The situation for a road cyclist is quite a bit different compared to skiers & riders on a ski slope.
On the road the light shines in the direction of the traffic behind you in the lane. The vehicles are all travelling in the same direction.
On snow in daylight you would need a very bright light that blinks in all directions to add significantly to visual impact of bright clothing. At night even a very modest amount of flashing red light will significantly improve your visibility from a good distance.

Anyone use a flashing tail light on their helmet? Like you see on bicycle/motorcycle helmets?
Seriously considered it for night riding.
Daytime, I'm with @Odd Job been wearing red snow clothing for 10+ years. Photographers know that red catches the eye in any image.

Or just made the screws shorter.

Your options are greater if you have smaller feet/boots. You have much more leeway to move your boot backwards or forwards along the binding.
At mondo 29 I'm unable to get my UPZ RC10 boot sole centre mark over the centre of my bindings (Bomber TD3s & F2 Race Intecs).
Instead I adjust using all the options available to get the toe of my rear boot at the board edge, and the heel of my front boot at the board edge (no overhang) while also achieving my desired stance distance and binding angles & splay.
Adjustment options are -
Adjust the binding angle
Move the boot backwards or forwards along the binding
Turn the binding discs so that they run across the board rather than along the boardI figure that in the end I want to tilt the board, and having the toes & heels aligned close to the edge is more relevant to that than the position of the boot over the binding.

@Chouinard You just need to find this post again. Glad to hear you found a solution.
I have a few "tips to remember" at the beginning of each season.

How well does it hold up in the cold? I use Loctite Hysol E-120HP as the nuclear option
Single application bridging the teeth on the adjuster and the gap in which it rotates has held through at least 2 seasons of use. It is the work of a moment to do it.
The F2 Intec front loop fits my UPZ shells beautifully otherwise. The things I've done to try to get the toe pressure evenly spread on my Bomber TD3s is a whole different story. There's a possible product improvement for TDs right there.

newer F2 Intec bindings have that adjustable front bail which is a terrible design as it loosens up over the day anyway.
Not with a dab from a hot glue gun. Been there.

Your RS binding toe pieces don't seem to have any vertical adjustment, unlike some other F2 bindings. You almost need to tape a 1-2mm thick shim onto the toepiece flat surface bring the underside of the steel loop to bear properly on the top of the boot toe block.

I hope they have some form for calibration so we can remove boot cuff flex from board inclination. Half of me really wants to get raw data, the other half knows that I would probably loose interest before I got any actionable info out of it.
I had wondered about the same and was thinking of mounting mine on the boot shell, or the board surface just outside my front and rear bindings.

Just about to buy my season pass for my chosen field for the coming Southern Hemisphere winter. I'm looking at riding in August.

Problem is they don't and won't support snowboarding. When I asked about the possibility to recalibrate it for use on an SB, just for data logging, they basically said: nope.
I was exploring the CARV website a couple of days ago. Was invited to trial run a couple of web pages relating to a new product they are developing. New version is just motion sensors clipped to boot cuffs, no sole pressure sensors, so easily exchangeable between boots.
They are now, as well as reporting turn angulation for each leg, reporting G forces experienced in the turn. The higher the G force the more powerful the change in direction, the better the carve effectively.
I think there is enough in the graphs the app produces that I can interpret for myself as an alpine boarder to make it worth my while trying it. I'm hoping the new version actually appears in time for me to trial it this Southern winter.
Ski IQ is a derived value to stroke the ego.
I have more interest in the data. Only one way to find out.

A real World Series, opening with USA vs Canada, starting 2nd June 2024
in The Lodge
Posted
USA passed the Canadian total (194) with 14 deliveries to spare. The USA might surprise some of the traditional cricket playing nations in this tournament.
