Cats with claws absolutely do cause damage to furniture (mine is ruined). If you care about your furniture you shouldn’t have a cat. I believe the morality laws around surgery on pets are something like “It’s ok to perform surgery on pets a

There’s no need to confuse things with metaphors as anyone with elementary understanding of maths should be able to understand it: A cryptographic hash function is an algorithm that: Given an input, it returns a very large number. Given a b

We wrote a tool that pulls in several open source tools, the most important of which is sqitch[1] - a beautifully simple Perl based tool for managing migrations that supports rollbacks and verifications - all written in SQL. All hooked up i

As with RDS Postgres, it's Amazon's fork of Postgres. With Aurora, the storage layer is swapped out entirely for a distributed storage engine, that I believe is based upon DynamoDB. The wire protocol and server interface are much

At a wild guess, I’d imagine getting something working probably took about 18 hours, with the rest of the time spent writing tests and defining behaviour of the legacy system to prove that the port actually worked

In my personal and subjective experience, working beyond 55 hours in a week is very doable... But it's absolutely not sustainable. I've found that doing it for more than 2-3 weeks in a row will generally result in declining produc

As a tool for rough approximations, spreadsheets are amazing. Beyond that though: * Lack of unit (or any) testing * Lack of good versioning practices and code review (e.g emailing around a sheet that's been doing the rounds for 15 year

CPython doesn't have a JIT. It compiles to bytecode, which is then "interpreted" by a stack based VM.

The problem with ESBs in my opinion is one of tight coupling; all of these distributed systems that know about and depend upon each other. The solution to this is to loosen coupling whilst formalising interfaces/contracts/schemas,

We run several million sorted sets, but they are all short sets (100s), but do thousands of writes/sorts per second without issue. From memory - there was a setting to turn on/off gzip compression for a list once it went beyond a

The lack of automated result > data model mappers is kind of by design with statically typed languages. IMO, Go's structs approach is much more lightweight than languages like Scala where large amounts of time can be spent defining

The advice we were given, and my general understanding is that you absolutely have the right to use IP addresses for network diagnostic and [anti-] abuse purposes. What you can’t do is leave those IP addresses lying around unsecured, share

For passwords, yes, this is generally best practice. Also, the salt is normally stored with the hashed password, as it’s not regarded as a secret. Modern GPUs can manage several thousand million SHA256 hashes/sec, so even with a salt p

Many accountancies (at least in the UK) will, for a small fee let you use their address as your registered company address, and some will either receive mail on your behalf that you can, or forward it onto you.

Oh but it does. And even when it’s not great, it’s usually a less horrendous task to refactor into something better.

I used to hate Java, but years of experience later, I would gladly inherit a well maintained/architected and modern Java codebase over anything written in Python or Ruby (even a well maintained one)

^^This, exactly. First see how far you can push a decent relational DB, then try harder. When you really can’t push it any harder, or it becomes uneconomical to do so, _then_ look at graph solutions.

Not a particularly easy solution, but you can use dynamo streams to achieve this by loading fast into a temporary table, trickle-feeding via a stream into another table. When it’s caught up, stop writes on the import table then swap over to
