That's a good point, I suppose it'd be better to frame it as what you can run on a $1k workstation vs. a $10k rackmount server, or something along those lines. As a software engineer who builds their own desktops (and has for the

The version I've heard is that small data fits on an average developer workstation, medium data fits on a commodity 2U server, and "big data" needs a bigger footprint than that single commodity server offers. I like that bett

attrs also has a feature that dataclasses don't currently [0]: an easy way to use __slots__ [1]. It cuts down on the per-instance memory overhead, for cases where you're creating a ton of these objects. It can be useful even when

I've been very happy with Wallabag as a Pocket / Instapaper replacement. Self-hostable, with an option to pay 9 EUR/year for a hosted version.

Note that it's not either/or - you can dispatch work from an event loop to a thread pool (or a process pool) with loop.run_in_executor [0], while loop.call_soon_threadsafe [1] can be used by worker threads to add callbacks to the

If you want a middle ground between hand-written shell scripts and full-blown Kubernetes, we use Hashicorp's Nomad[0] on top of CoreOS at $dayjob and are quite happy with it. Similar use case - self-hosted VMs, for low-traffic, interna

The key difference between "classic" RDS and Aurora is that classic RDS really only automated the control plane. That is, RDS spins up an EC2 instance (or two, for multi-AZ) on your behalf, attaches an EBS volume of the appropriat

At that point you're not writing JSON though. Once you start bolting on non-standard bells and whistles, why not recognize that JSON was never meant to be used for config files, and switch to something that was, like TOML [0]? 0: http

I'm a very happy fish user but this is one of my pain points as well. If you want to define a function, the syntax is light-years ahead of bash, including named arguments (and closures!), but it took a fair bit of googling and eyebrow-

It's possible to have both randomness and reproduciblility - generate a random seed, log it, then explicitly seed the RNG. If you encounter a failure you suspect is caused by a particular random seed, temporarily hard-code that seed wh

If you want to read about the theoretical underpinnings, Cassandra is derived from the original Dynamo paper[0] from Amazon, and Scylla is a drop-in replacement for Cassandra written in C++ instead of Java. Cockroach follows more closely th

If I'm reading the underlying docs correctly, previously you would have called ChangeResourceRecordSets[0] with a quite verbose XML document. It looks like you'd need to first query for the existing RR set, modify it, then update

For higher-end home connections (100mbit - gigabit) those older "Wi-Fi aisle at Best Buy" type of routers may or may not be able to saturate the connection. By separating the router and wireless APs you also get the ability to pla

The cable bundling isn't scare-mongering, it's a real scenario (but a worst-case one). It also serves the purpose of being something I can explain to less-technical relatives at the Thanksgiving table, and they immediately grasp t

If you're unconvinced, you should default to supporting net neutrality. It's the status quo, the null hypothesis. The burden of proof is on the people wishing to make this fundamental change to the structure of the internet.

I'd argue that the more large/complicated/nested the JSON structure, the more it would benefit from using a "real" database instead of a JSON file sitting on disk. If not SQLite due to document-relational mismatch,

That strikes me as being comparable only at the most superficial level. I started that SQL Server container and it's using 825mb of RAM (according to systemd-cgtop), just sitting there idle with no data in it. I started a Postgres 9.6

CPUs with hyperthreading typically allow you to disable it in the BIOS. If you're running a new, beta-ish CPU microarchitecture (such as Ryzen/Threadripper) you might wish to disable HT as part of troubleshooting a CPU freeze&#x2F
