I use a daily log system. I just run this bash script to open my log for the day. This opens the same file all day, so I can add stuff, and I know how to find old stuff, it's easy to grep, etc..

    ## create new log file for personal logging

    vi ~/daily_logs/personal_logfile_$(date +%j_%m%d%y)

Yeah, I'm not a frat guy, but don't groups like Fraternities build "Study Guides" that are often just brain dumps of tests with correct answers?

We called them "bibles" in undergrad and they were collections of homework and tests from previous terms.

The most consistent misunderstanding I see about the cloud, is disk I/O. Nobody understands how slow your standard cloud disk is under load. They see good performance and assume that will always be the case. They don't realize that most cloud disks use a form of token tracking where they build up I/O over time and if you have bursts or sustained high I/O load you will very quickly notice that your disk speeds are garbage.

For some reason people more easily understand the limits of CPU and memory, but overlook disk constantly.

At one time I had a project to run a cryptocurrency node for BSC (this is basically a fork of Ethereum with all the performance settings cranked up to 11, and blocks centrally issued instead of being mined). It's very sensitive to random access disk throughput and latency. At the time I had a few tiny VPS on AWS and a spinning drive at home, so I evaluated running it there. Even besides the price, you simply cannot run it on AWS EBS because the disk is just too slow to validate each block before the next one arrives. I spent a few hundred dollars and bought an NVMe SSD for my home computer instead.

Even without that, you are still at the heart of it accessing over a SAN like interface with some sort of local cache. Getting an actual local drive on AWS the performance is night and day

Sure, you can work around it; but it blows up the savings alot of people expect when they don't include this in their math.

Also, SAN is often faster then local disk if you have a local SAN.

How is a SAN faster than a local disk? Any references / recommendations?

Probably comparing a HDD SAN (with data spread across many drives) to a single local HDD.

I would expect by the magic of parallelism?

What could I read to inform myself better on this topic? It is true I had not seen this angle before

This looks pretty informative. The terminology can be hard to follow. https://medium.com/@bounouh.fedi/understanding-iops-in-aws-w...

I/O is hard to benchmark so it's often ignored since you can just scale up your disks. It's a common gotcha in the cloud. It's not a show stopper, but it blows up the savings you might be expecting.

half the time, no sugar means sugar substitute. It is definitely confusing.

Glad you're hear to tell people they are dumb and they should work around systemic problems instead of trying to fix the system.

They do now, that's why they are using a shell game to pump up the stock value.

The one thing Democrats and Republicans always agree on is "No Progressive's allowed".

Indeed. Progressives are an existential threat to the current geriatric establishment owning the party, and they recognize them as such. They would sooner see the country in the hands of fascists than enact a single left-wing policy. Just look at Schumer, Kamala and their pals still refusing to endorse Mamdani, the one Democrat that has been able to generate any amount of momentum in years.

To the Republicans, Progressives are a political force they might actually have to try winning elections against, if the latters are ever able to muster a modicum of power inside of the party that is supposed to house them. A progressive Democratic party with populist messaging would certainly mean they can't rely on the absolute ineptitude of their opponents campaigning anymore.

Yup, these guys aren't the customers anyway. The investors are the only ones they care about because the customers don't come close to paying the actual costs.

I distinctly remember a kid dying by falling off her bike in the late 80's. She was in the class w/ my younger brother but we didn't really know her. It was obviously a big deal at the school.
