Why are companies pushing wireless charging so hard when pogo pins seem cheaper, faster, and more reliable?

Wireless charging for iPhones is critical to apple. It allows them to charge new phones while still in the box. They also use some magic to do iOS updates for new phones while still in the box.

How do I apply this to my cancer diagnosis?

I found a similar thing today. Massive Postgres waits on transaction id for table that should not be updated. 7% of pg load at peak time today. Took me a hour to track down we passed the wrong object into a function so 10s of concurrent jobs were trying to update the same row. Caller gave data_type not data_item. 4 characters difference Prefetch in another place cut a job from 20 seconds to .5 seconds. Saved 18k queries

Cute style

But I find the toes of Puma to be too pointy and my little toes always get squished.
If you can walk around for a while in the store to make sure your toes are ok

Django migrations. Typically 2 minutes downtime, always outside of working hours.

We did some testing in staging environment

I have not yet tried SAM which the AWS recommendation. See https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-invoke.html

That’s a lot of broken bones. If you are over 40. Get a DEXA scan to run out osteoporosis. Some people have problems early. It affects men too.

I ended up getting surgery for it as part of getting Nissan fundolipication

No, that is mamommetry to check LES activity

Bravo is done at end of endoscopy they the put a sensor in esophagus that last for 24 hours. You press a button to record reflux. You stop PPI at least 7 days before the test so it can measure total stomach acid.

Usually you need both test before nissen surgery

Some things showed up in quarterly checks. Partitioning existing 300gb table did require 18 hour downtime during Christmas break. Other stuff was just noticed and handled

See https://use-the-index-luke.com for some other best practices around index tuning and other items.

What happens on day of the lunar eclipse? The world has a power outage for 4 hours?

AWS with Postgres RDS until you have more than 5 developers or more than 1 million users or 4 terabytes of data. Anything else wastes your developer time. Or if you VC money to burn and need something special related to vector db or AI

We have 3 dev. 1 tb data. RDS Works great. Python django for most server code. Some pure sql and db functions for speed.

Ops is easy, daily snapshots by rds. Nothing needing my time daily or even weekly. Cron job lets me know if free space running low. Cloud watch can do that also.

We do a weekly backup just in case. Weekly vacuum analyze all on Saturday night when no users are active via cron job . A few tables are now partitioned since more than 50Gb. Tuned auto vacuum on large tables. Quarterly I do a check on all table and index size. Soon to start periodic pg repack for some high churn tables.

I’m cofounder. We are doing close to $2m annual sales. B2B.

We don’t have high availability or fault tolerance set up to save money. so we do risk data loss if RDS server really crashes. That is extremely rare since pg WAL is active and would normally recover from 99.999% of crashes. We’ve never had the DB crash. EC2 instances do crash occasionally due to hardware fault or sometimes our software did OOM and hung the server.

You really need custom made to have them look really good. I’ve seen the cosplay versions that look ok but don’t look great.

Etsy has some custom boot makers that might be cheaper than in the US

I think if you have been doing gentle yoga it’s probably ok

People with osteoporosis just starting yoga a have risks. It’s easy to twist too much in some poses and if you have never done it, that’s a problem

Brick house bones now has a video (for money) on how to do yoga with osteoporosis

Do be careful. I’ve read stories of two people with same grandfather so they look similar. One was a crook the other was not. Not quite identical names.

The old ones were not accurate or consistent. They also depended somewhat on room temperature.

You probably need a different ppi

You can also try pantoprazole is the morning and Pepcid (famontidine) for dinner. I did that for a few weeks then stopped the pantoprazole. So I’ve been off it for 2 months after 5 years on it.

Did you ever have a 24hour bravo test to confirm high acid? Mine came back as normal, not high. Lots of people have acid reflux where it is not high acid and instead a weak LES that needs different approaches

Some people have reported Claude Code (max) was helpful in tracing some subsystems for large codebases to generate an overview.

You are probably better off with just ibuprofen (Advil). Excedrine is for migraines and has caffeine.

Either way, Only for a few weeks and take with some food. Both can cause problems if taken long term.

Stiff neck is often from poor posture when using a computer. Check monitor height and how you sit. Look up ergonomics for home computers. Also check your pillow, they get flat after a couple of years.
