> batching multiple transactions into IO blocks where feasible. If your average transaction is substantially smaller than the IO block size, then you are probably leaving a lot of throughput on the table.
Could you expand on this? A quick Google search didn't help. Link to an article or a brief explanation would be nice!
Sure. If you are using some micro-batched event processing abstraction, such as the LMAX Disruptor, you have an opportunity to take small batches of transactions and process them as a single unit to disk.
For event sourcing applications, multiple transactions can be coalesced into a single IO block & operation without much drama using this technique.
Surprisingly, this technique also lowers the amount of latency that any given user should experience, despite the fact that you are "blocking" multiple users to take advantage of small batching effects.
I've had those options on multiple OnePlus phones, but they were not present on multiple Pixels. Since Pixels are usually sold as "AOSP experience with Google flavor" are lacking this feature - I am not sure if that is that feature comes from AOSP or is only present on OnePlus phones.
I've generally found them on most Android phones, but they're all over the place in the settings. On my current phone they're not in permissions, or connections, or internet setup, or security, but they're in the app details screen.
I've also seen the toggles placed in the data usage graph, the other, older data usage graph you can sometimes find via a workaround, and in a separate app that pretends to be one of those system storage optimizers.
I'm sure Android supports it at the system level but how you get to those settings is anyone's guess, really.
Forget about DataClasses, TypedDict etc.
Can't you achieve the same in python with a class and a dict? Is there a difference, other than perhaps being overloaded with options?
There’s also implementation differences. Accessing attributes and methods on a regular class may be slower because (IIRC) it has to do a lookup on each instance’s dict, whereas I believe dataclass implementation is more optimized (I’ve clearly forgotten the details).
Many people think that, in the time of the USSR, Russian chess players conspired to make sure a Soviet player won tournaments.
For example, they would try harder to beat strong non-Soviet players than to beat strong Soviet players, would throw away games to give a Soviet player more points, would offer a draw very soon to give a Soviet player time to rest/prepare for theirnext matig, etc.
When I was implementing SimpleDB in 2019, I believe CMU's course didn't have resources and lab assignments that were publicly available. Now CMU has published a full video lecture series (which MIT doesn't have) and their labs. So if I were starting again today, I would probably go with CMU's course.
Here's an article from the NYT about how they are trying to ethically sell Hunter Biden's artwork. "Ethically sell" was a term I chose specifically because Hunter Biden is not an artist, and the question of why his paintings are being sold for half a million dollars and to whom is substance.
