arpinum··on Just use Postgres
I didn't say it is a usp for mongo. Only saying that there is a lack of substance behind the mongo criticism in the article.
arpinum··on Just use Postgres
except its factually incorrect when applied to Mongo[1].

arpinum··on Just use Postgres
sure. 1. sqlite can have more than 1 file when using wal mode. 2. You don't need to know your exact dyanmodb access patterns upfront, you can evolve the schema. again, not worth effort to point out more.

This sentence has no substance. It gives the reader nothing to understand why MongoDB has both happy customers some who have been disappointed.

It's not worth pointing out the technical flaws in the post[1]. It is obvious the author does not have a strong grasp of the tools he is criticising. A better example of this style of post is Oxide's evaluation[2] for control plane storage that actually goes over their specific needs and context.

This isn't true and the link to the source is a 404 page. It was already too much content marketing, no need to read beyond that line.

Similar to ship, they start up more engines than needed in case a few fail, then immediately shut down the extra engines.
arpinum··on Taking Risk
Same experience in England. There is little celebration of business success and more likely accusations of exploitation.

The class system is also alive and well in business - the ambition of many well off uni students is to manage others. Grinding on a startup doesn't fulfil that class ambition

arpinum··on I organized a 20-acre game of Capture the Flag
great memories as a kid playing 48 hour CTP in 100 acres of woodland. Camo, tackling, building prison cells, escaping from prison, getting lost for hours. Built character.
arpinum··on Cardio fitness is a strong, consistent predictor of morbidity and mortality
Bicycle helmets are not designed for impact with a car. They are designed to handle falls to the ground. The forces are quite different.

arpinum··on Slashing data transfer costs in AWS
Another trick is to use ECR. You can transfer 5TB out to the internet each month for free. The container image must be public, but you can encrypt the contents. Useful when storing media archives in Glacier.

arpinum··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
All of these fail an inspection. If you are at a mechanic they may fix these issues during a pre-inspection if they have parts available.
arpinum··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
Because faults can include items such as the first aid kit expired, tyre inflator expired, headlights out of alignment, a crack in the windshield wiper, worn tyres, worn brakes, or low washer fluid.

These are not initial build quality issues.

And my claim is that during a yearly maintenance any faults are found and corrected before the HU inspection. If you don't have a yearly maintenance then you have a longer time period for faults to develop. Or for items to expire, like a first aid kit.
arpinum··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
Inspection interval is the same, but maintenance interval is different.
arpinum··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
This is not about failure rates or an indication of quality. This is faults found during a scheduled inspection.

Normally this means finding faults that occur since the last maintenance interval. If a car has a long or no maintenance interval (like Tesla) then more faults are expected.

Also note that failure can mean windshield wiper needing replacement or headlight re alignment rather than a premature part failure.

arpinum··on Daily energy expenditure through the human life course
The question is about base metabolic rate, not energy expenditure from exercise.

Fidgeting is a non conscious act performed throughout the day, it is not exercise. Exercise can actually reduce fidgeting and this shows up in athletes lower BMR that needs to be taken into account for meal programmes.

It is easy to eat more calories than are used in taking 10.000 steps.

arpinum··on Daily energy expenditure through the human life course
Fidgeting.
arpinum··on Google Cloud Spanner is now half the cost of Amazon DynamoDB
> and there isn't an obvious way to get more than 100 nodes per table

By node you mean partition, and a partition is limited to 10GB. Store more than 1TB and you will have at least 100 partitions

arpinum··on We’re opening up access to Gov.uk forms
gov.uk is not a monolith, different departments can make different decisions. There is no mandate for AWS containers or Fastly CDN.
arpinum··on AML works, even if it intercepts less than 1% of criminal proceeds
Most financial institutions in my country of residence will not have me as a customer because I hold a certain foreign passport. I'm too expensive to service because of these AML / KYC laws. And we know it is because of these laws as they stopped accepting me as a customer when these laws went into effect. There is exactly 1 financial institution in the country that will have me as a customer, but even then I am restricted from buying most of their products.
arpinum··on Imaginary problems are the root of bad software
Author gets it half right. Too many developers trying to have fun by doing new things. Affordable initial software development tends to come from places that have boring templated solutions using 1-2 tools.

But the main argument is off - What some classify as imaginary problems is actually building in the wrong types of affordances. The only way to know the difference is by knowing your tools and the problem domain.

The root of bad software is leaders lacking practiced learning.
