Which you could’ve easily done with S3 Batch Operations or the EMR-based sync in a super-parallel way and little engineering effort.

I’m surprised none of the engineers either knew about, or thought to ask AWS support, S3 Batch Operations or S3 Replication. Both of which could’ve completed this process in a relatively short amount of time in a completely hands-off way. W

You pass “numbers” to DynamoDB as strings defined with the type N. As long as you aren’t using a floating point initially, DDB isn’t going to add any floating point imprecision itself.

Not sure about how Clojure treats numbers, but in DynamoDB these are treated as Decimals and don’t have floating-point rounding errors.

It uses DynamoDB and transactions. Each double-entry appears to be 4 items, 1 for each balance update and 1 for each transaction. Each “journal” will use 2x4 WCU for the write to the table and 4 WCU for the global index updates (a total of

As with all things AWS, it depends. Yes EFS is 30¢ per GB and S3 is 2.3¢. But S3 also charges $5/million object writes (and 40¢ for reads), but EFS is "free" (factoring burst capacity, per-instance maximum throughput limits,

It’s always been confusing because that 50ms is actual CPU time, not to walk-clock time. Whilst it’s great to be billed on actual usage, it’s hard to tell how expensive a function is going to be.

A lot of it is developers not understanding, being aware of (or simply being uninterested in) the problems other businesses face. And businesses not knowing what _can_ be done with software to commission developers to solve it for them (or

Maybe it's the wrong approach, but I treat an entire interview as back-and-forth conversation… especially for a specific position. Questions demonstrate curiosity in the role you're being hired for and give you an opportunity to d

I have one of the new Magic Keyboards in front of me now. I had the same reservations as you before trying it out (and it’s a little hard to tell because all I have to rely on is my meat brain’s interpretation), but it feels like the cursor

But there are literally 100's (or more) of banks around the world that use AWS for compute. They meet all the security requirements you could want (27001, SOC2, and many others) around how they secure and limit access to servers by sta

Although, most of that $4B will probably be spent on finding and onboarding hundreds of thousands (175k so far) of new staff to deal with the demands on the retail business caused by COVID-19.

This is cool, but the EFS infrequent access pricing for Australia looks wrong. Shouldn't 100GB cost $2.72 (not $1.20)?

Assuming you should already own a chair that shouldn’t be worth less than about $1k (or a bit less than that second-hand) is a bit extreme.

"They managed to accomplish some great things" in spite of being jerks to each other. Imagine what they could've accomplished if they had empathy and were collegial with each other.

It replaces on demand instances in-place. If there’s no spot instances, it will leave them running. If the spot instance gets killed, it will start again as on demand. It sounds a bit hinky, but it tends to leave you with the number of inst

It costs roughly $5/million PUTs and $0.40/million GETs on S3 in addition to the bandwidth and storage you use. S3 objects are also immutable. Once they’re written, they can’t be updated. A read-only version of this might be usefu

If that's your concern, lean on Firebase. You have to use Firebase to deliver messages to Android anyway, having it deliver to APNS as well you get for free with that implementation. Maybe you do want to do those things, but this i

They’re only using Firebase for Android delivery (which is mandatory anyway). But it is just as happy to deliver to APNS at $0 as well with near infinite scalability. The actual delivery component of their messaging system is unnecessary.

I don’t mean to discount the work done here, but why would a dev team build this themselves these days? There are many practically infinitely scalable services that do just this with various levels of sophistication. From the simple AWS SNS
