RDS is extremely expensive. All managed databases are.

That said, it's a trade off of convenience and being in the AWS bubble, and weighing up the pros/cons of separating out services. Data Transfer is another thing to consider too of course. Sticking your database elsewhere might cost more in egress traffic communicating with it from your other AWS infrastructure. If you're all in on other AWS services, sometimes the RDS price is just worth it when it comes to the total price. Sound like this might be the case for your setup.

I hope you do manage to work things out. The service you have is great.

PS - Side note on RDS sizing. You might already know but sometimes it's worth increasing the storage size on gp3 type storage above 400GB (if you haven't already) as you get 12,000 IOPS baseline against 500MiB/s throughput[0] when you have that much storage. That's 4 times the below 400GB baseline performance but you only pay for the additional storage cost. It can make a difference if you're IOPS constrained or trying to deal with bursty traffic but want to use the smallest instance size possible otherwise to save costs.

Some Nalgene's are polycarbonate, like those commonly drunk from. But not all, some are HDPE[0,1,2].

Some are Polypropylene co-polymer[3] but those are more for specialist things I guess.

Replace the highly curved spacetime region close to a blackhole with the idea that huge amount of spacetime is being created by the mass of the blackhole, so there is more spacetime near the blackhole.

The more spacetime being created and 'flowing outwards' away from the mass, the faster the apparent 'velocity' of an object through that region of spacetime ner the blackhole (and have this work out that the spacial component handles the physical motion and time slows down to compensate - just like it does in highly curved spacetime), and consequently the slower it moves relative to an external observer.

Areas further from mass see much more 'dilute' spacetime (whatever the heck that means) and travel with relative slower spacial velocity but faster in time, so it appears to be travelling faster up. This would be doubly obvious at the scale of galaxies.

I think this ridiculousness would rely on the relativity of simultaneity in rather a large way!

The other interesting thing is, if mass does create spacetime then pockets of mass like galaxies should move away from each other faster and faster as they make more of it in between themselves.

(NOTE - this is just a silly thought experiment, don't take it seriously)

I am very fortunate to have excellent visual acuity, low light sensitivity and am extremely sensitive to colour/different shades or tones. There are test you can do online for this if you have a well calibrated screen. I also used to be a photographer and worked for years in low light settings documenting events. So I have put that good fortune in the genetic lottery to good use!

So for me, I absolutely saw the full colour display very strongly. I could see variations in colour throughout the height of the column and i could easily make out the striations between the different filaments. I could also easily see the curve of the bands across the northern sky. The colours to me were as obvious as the orange of light pollution you might see from a nearby town. I could see the low level patches of cloud silhouetted against the green and the huge bands of red/pinky red towering up into space.

What I will say though is that even looking at my phone was enough to dull the experience. And minimally strong light in the eye instantly desaturated the colours of the aurora and took a minute or two to recover. So you really do need dark places, dark skies and to really let your eyes full adjust to their maximum possible sensitivity.

His latest on the topic is cool too: https://www.youtube.com/watch?v=ys7yUyyQA-Y

He's has quite a lot of content that HN folks might be interested in I think, like the reality and woes of consulting[3]

The study had people click on photos of where their interest would be if they were walking. They were not eye-tracked when actually walking. This is a significant difference. Particularly because at night your peripheral vision is much more acute at detecting shape/silhouette/tonal variation and in my experience also motion. The latter is very relevant for detecting threats.

I was poor growing up had to walk a lot, including at night. A lot of time was spent walking in not the best areas! Most of my teenage life seemed to be spent in the dark too, if I ever wanted to see friends! And then military service with endless night exercises. Add to that living in the UK with 17+ hours of darkness in the winter. I can definitely say that after decades of walking at night and many many thousands of miles (I have a nearly 200 already this year already) you learn there’s a certain way of ‘seeing’ without looking at something directly. So I very much question the claims of the study in so much as it states where your eyes actually look when walking in real world circumstances.

What I don’t doubt is that in general women have more to worry about and fear in public spaces, that their attention is drawn to different things than men in some circumstances and that there likely is a difference in scene scanning behaviour.

A proper study on this would be very interesting to see and might actually help better inform the design of public spaces for night time use.

The reason I did it is whilst lying down or in very confined/concealed area it’s easier to turn your wrist to see the time, which passes amazingly slowly in these situations. If you imagine you arm outstretched in front of you it’s a lot easier to see the watch face if it’s on the inside of the wrist as you have to turn your arm much less.

I’m not sure I am explaining it adequately, but it these circumstances it’s definitely easier.

At all other times and in my normal role I never did this.

Regarding light discipline, many brands make military versions that are much harder to accidentally press the backlight or in modern tomes allow you to turn off the heartrate monitor lights. Also, we would generally wear long sleeves which would cover a watch in most situations anyway, even in hot climates. There was a gradual mover to 3/4 length or turned up sleeves during my time, when watches would then often then get covered by tactical gloves or sometimes even dedicated covers made to conceal a watch.

USB Foot Pedal is just one random search that’ll show this.

Mens fleece hoodie, audio recorder, iphone case and electric blanket are full of random named crap.

The problem also extends past these random products and into the seller market too. Even if you search with brand names for a product you want it’ll often be sold by some random new seller preferentially selected due to price undercutting.

The whole platform is rotting from the inside out.

I know. I’ve experienced it first hand (as the kid).

To your point about deliberate choice: What I do recognise from the article, and it was clear before she mentioned it, were the signs and symptoms or untreated trauma and ADHD. The deleterious effect of those conditions on decision making often seem to us observers as ‘deliberate choices’. This can be very frustrating for those of us who would and do make different choices in similar situations.

> Choosing to use the powers vested in you by the constituencies you serve, to deprive those same constituents of light, heating, food and home security is a wilful and deliberate act. And it has to stop.

It’s abundantly clear that the whole passage was speaking to Rees-Mogg, calling her out for her Marie Antoinette ‘let them eat potatoes’.

This passage isn’t a generalism, is a specific response to the words of a former politician, a former Conservative MP and MEP for East Midlands.

To reduce the articles substance to a specially selected out of context quote such as OP highlighted seems disingenuous.

It has so much promise but the 'lead by committee' approach just resulted in some kind of collective 'demand avoidance' from the devs who seem to revel in delivering an unusable product. And I mean unusable for those not willing to learn an entirely new paradigm of interacting with a piece of photographic software and dive into the docs for everything, including stuff as silly as a keyboard shortcut or move between modules.

I've yet to read all the Ansel blurb but I'm pretty sure this is from the guy who's made the most improvements to Darktable in recent releases. So it's incredibly exciting to see.

I doubt it'll get any DAM capability though, even for a fork that is asking too much :-)
