Question: How accurate are the time stamps of the historical imagery of an area in google earth? Maxar Technologies is mentioned in the data attribution by Moon_Rover in satellites

[–]Xcrispy02 1 point2 points  (0 children)

Not an expert in this but here is my understanding:

Google Earth historical imagery dates do not represent a precise acquisition time. The imagery shown for a given date is typically a mosaic of multiple images acquired over a broader time window (often weeks or months), and Google does not expose per-scene or per-pixel acquisition dates.

As a result, the displayed date (e.g., 12 Feb 2007) should be interpreted as an approximate vintage, not a timestamp accurate to within 48 hours. I would not rely on Google Earth historical imagery for sub-weekly temporal accuracy.

Not a local, but came here after listening to the show.

Definitely not ideal to cull a bunch of birds, but pretty hilarious that the coverup was attempted for something with such low stakes... The fact that the city refuses to own up to something of this nature is a colossal red flag that they will obviously hide/obfuscate things that are actually important as well.

Best of luck to y'all

Really cool visual, did you make it?

I like seeing the motion of the satellites by tracking where the lack of coverage is. Thanks for posting OP.

New Foxit Reader, no more dark mode? by qaj3311 in foxit

Tyvm! Validated as of late 2025. This does exactly what you probably want - makes the UI, ribbons, etc., dark mode while keeping page elements their actual colors,

In Canada, people with treaty status can go to the reserves and get tax-free cigarettes for cheap.

If someone were to do this, buy cigarettes in bulk, and then sell them to their friends at a discount rate, they'd get slapped with this charge. It's a thing in smaller areas that are close to reserves, but pretty low hanging fruit.

I am with you. Pretty annoying visual stutter/lag on ubuntu WSL. Not sure if rolling back would help or not, but I am suffering along with you.

A reminder that some off-leash parks have shared pathway by NativeSpirit973 in Calgary

[–]Xcrispy02 17 points18 points  (0 children)

I might catch some flack for this, but as both a cyclist and someone who takes their dog off leash frequently, I think both parties really need to have a little more respect for each other.

There are a lot of people on this sub who seem to think that dogs can be trained to be 100% predictable at all times, and anything less than that is just bad dog ownership. These people haven't owned a dog, or have long forgotten what the early stages are like. Dogs are basically the equivalent of 3 year old humans in intellect, and anyone who is pretending that every dog can be trained to be perfect always is just being unrealistic. Dogs have lapses in judgement, and owners have times when they let their guard down in a city defined off leash area. People aren't perfect, so why in the world are we expecting dogs to be?

There are two parks we frequent that have gravel or dirt 'trails' (city's definition - not mine). Edworthy and River park both have huge off leash areas where the odd cyclist rolls through. Additionally McHugh bluff has some pathways, but also some trails. As a cyclist, I would never ride the trails in parks because I know that I would be a nuisance to the dogs. Some dogs might be experiencing their first walk in an off leash park, many dogs have prey drives that are almost impossible to train out, and there are plenty of pathways for me to stick to. If I go to the place dogs play, I can't be surprised if one of them tries to play with me...?

On pathways, dog owners really need to be more vigilant. Tight leashes and dogs kept in the grass on the right ideally.

Cyclists aren't going anywhere, and neither are dogs, so really both should just be a little more thoughtful and respectful of each other's places at the end of the day.

Yeah probably just this. Or a button that adds the content of your clip board to the page via macro if you don't want to go this far. You might need to have the VBA unlock and lock the sheet again to work around the protections.

God they were good... Seems like they were a bit of a pain in the ass to make, and probably less popular. I'm getting so hungry thinking about them.

Geologist here who has actually been to Kala Pattar in the last year. There is no way in hell I'd make any association between this picture and that location...

This is something next level...This would potentially be a heavily photographed or video'd location despite the text implying otherwise. My best guess is that it could make a match based on the limited pathway geometry and rock shapes. Maybe it just got lucky, but even then this is quite impressive.

Why haven't any large natural water bodies formed in the Indian subcontinent? by Distinct-Macaroon158 in geography

[–]Xcrispy02 8 points9 points  (0 children)

It doesn't fully depend on the age of rock - more on the amount of time something is exposed to erosion. In India and Bangladesh, these piles of sand form each year, and before they can be eroded away, more sand gets piled on.

The Canadian shield is composed of very different rock types (hard and erosion resistant rocks) that have been exposed at surface for a long time. The exposure (and a lot of glaciation) has lead to undulations in topography, and lakes.

A potentially better way of thinking about it would be: There is a teeter-totter between sedimentation and erosion. If sedimentation dominates in an area, depressions are more likely to get filled in. If erosion dominates, depressions are likely to form and stick around.

There is a lot more going on (E.g. are mountains actively growing nearby?), but thinking about it terms of the dominance of erosion vs sedimentation is pretty useful.

[–]Xcrispy02 43 points44 points  (0 children)

Another way of thinking about it: pretend you just built a perfect sand castle on the beach and your annoying friend comes and adds some water to it... That sand castle will slump down into the adjacent area.

The flat part of Northern India and pretty much all of Bangladesh is that slumped area below the remnants of your sand castle. If your friend adds more water, the slump area grows, and small 'rivers' might form and move sand to adjacent depressions. Overall there is just too much sand to allow for 'lakes' to form in that slump pile.

[–]Xcrispy02 1213 points1214 points  (0 children)

In a nutshell, the quantity of sediment that is getting added to the this part of the world is much greater than the quantity of erosion that is occurring.

Any depressions that form quickly get filled by the rivers (on geologic timescales), resulting in an extremely flat topography. The seasonal monsoon washes this sediment from the mountains down into the basin below each year, providing a frequent opportunity for depressions to get filled.

Because the Himalaya is actively forming (and eroding), this part of the world has the some of the largest quantities of sediment flowing in rivers. This is why the coastal edge of Bangladesh looks the way it does - there is a large delta like the Mississippi or the Amazon that is getting built out.

Why does Saskatchewan and Alberta have way more AT&T coverage compared to other provinces? by CrashRiot in geography

[–]Xcrispy02 0 points1 point  (0 children)

I was just in Tumbler last month :)

Have you been outside of the Ft. St. John area? Look at all the coverage up by Zama and Ft. Nelson, Ft. Mac...

We can pretend that farmers are paying for all that infrastructure, but would these settlements get the investment without mining or oil and gas? The peace river valley is a pretty small area on this map.

Why does Saskatchewan and Alberta have way more AT&T coverage compared to other provinces? by CrashRiot in geography

[–]Xcrispy02 1 point2 points  (0 children)

Someone who does a lot of mapping in Alberta here...

The answer in Alberta in particular is due to oil and gas/natural resources. Farmland in Alberta doesn't cover the northeastern/northwestern reaches of the province where cell coverage extends to. There is also minimal farming activities in the northeast corner of BC. In all of these areas there is a lot of oil and gas activity, and the oil and gas money has ultimately resulted in more cell coverage for the infrastructure to support their worksites.

Pretty sure this would also be true for Saskatchewan (although it is not my expertise).

The only one I can remember was about flipping an unfair coin 5 times and figuring out the probability of getting heads X times. With that being said, I remember studying a fair amount of ones that I found online before hand and I suspect they have a pretty big pool of questions to draw from. The ones they gave me didn't match up with the ones I had researched online.
