humanfromearth··on Pick strong consistency whenever possible
No major issues. If you're moving from a single node PG to CRDB you should expect CRDB to be slower because of all the consensus stuff. However almost every update I see from them contains some improvements in that area so it will get better with time probably. You just need to figure our if you're willing to accept a 2ms - 1m (PG) query execution vs 20ms flat execution (CRDB) - even after all the optimizations.
humanfromearth··on Pick strong consistency whenever possible
We use it as an insert only db for now for incoming webhooks which allows us to de-duplicate events and significantly reduce writes to the main PG db. We're running it on GKE which has been much easier to setup than PG.

There is also TiDB which is similar in some ways to CRDB: https://pingcap.com/en/

humanfromearth··on “Follow-The-Workload” Beats the Latency-Survivability Tradeoff in CockroachDB
Really looking forward to see this in action. Is follow the workload already present in 1.1.3?

Is there a bit more detailed technical doc on how this is actually achieved ideally with some examples? When is it decided that the lease holder moves from one node to another? Is it based on some sort of stats?

Edit: found the doc follow-the-workload here: https://www.cockroachlabs.com/docs/stable/demo-follow-the-wo...

You're right. I meant hard reboots.
humanfromearth··on Discord Postmortem from Friday
We had the exact same issue with RMQ (HA setup) on GCP (running on GKE) a few weeks ago. Tried contacting support about this, it's paid - no customer support for their own bugs.

The solution we came up so far is to disable automatic migrations. Not sure if that option actually does anything.

Same here, perf is obviously great, but no more crazy dependencies is just great! So much time I wasted trying to make it fit into a docker container.
humanfromearth··on A tall chimney to facilitate heat exchange in the atmosphere
From the FAQ. His answer is:

> Air inside the chimney is not affected by adiabatic cooling. Unlike freely rising parcel of air, the air in the chimney is restricted in its horizontal expansion and thus, it is not free rising. When air rises in the chimney, it also expands but only into upper direction. It compresses the layer of the air above it, heats it up and loses its own heat. At the same time the air below does the same thing. And that how it goes all the way until the chimney exit: layers of air are being pushed and push themselves. That results in maintaining the same amount of heat in every layer of air, and that is why the chimney works.

For the 5km chimney it needs to hold on 500km/h winds. For scale a category 5 hurricane is 250 km/h. Is it even possible to have that kind of structure with existing materials?
humanfromearth··on Making Humans a Multi-Planetary Species
I don't get the fascination with this barren gravity well called Mars. Other than scientific curiosity there is nothing there of value that is not 1 billion times more abundant in the belt. I genuinely don't understand why there is this need to be multi-planetery species and not just space-fairing civ? the tech we need for either seems kind of the same to me, but the belt has a much higher return so what am I missing?

Kind of.. but you can set `restartPolicy: Always` and will always restart in case of failure.

humanfromearth··on Python, as Reviewed by a C++ Programmer
So monkey patching is bad you're saying? I agree that it's possible what you're saying about kwargs, but after about 6 years of python I've never encountered that in any of the code that I've worked on.
humanfromearth··on Python, as Reviewed by a C++ Programmer
True, but very popular packages are usually battle tested and type errors are very rare in practice in those packages. Most bugs I've seen are not because of the lack of a static type system.

There are solutions for this: flowtype for js or mypy for python (preferably with python3.5+).

Better yet, why not asteroids first? If we really want to be living in space, don't switch one gravity well for a much shittier one.

humanfromearth··on Flow vs. Typescript
Like the presentation said, if you have a small project then don't use type checking. If you work in a big project with a lot of code that you didn't write then it could help a lot.

Also you don't have to use it everywhere with Flow.

humanfromearth··on Sublime Text 3 marked as recommended build
Modern editors are much more that file browsers. They do static analysis, syntax colouring, linting and many more things (depending on what plugins you have installed). I still like to open a plain vim and just focus on the task at hand without the magic, but that's just not how most web developers work these days.

I think this is great, but you'd probably need to wear a EEG which is going to be a tough sell until we have something more compact.

humanfromearth··on Mark Zuckerberg's Free Basics argument doesn't address conflicts of interest
What are the reasons to believe that it wouldn't work?

ANRC (the body that governs communication) in Romania I think did more (by doing very little) for the Romanian economy than any other government agency. It's funny because we used to hate them for not allowing us to get more ethernet cables on the public infrastructure (which we payed for a nominal price) because of some safety issues. I was working as and admin working for one of those free for all ISPs. It's crazy how good and cheep the internet has become since then.

What happened is that in a small city (250k people) we had about 30 independent ISPs and we had gigabit peering between ourselves. Scroll 5 years, big companies come in and buys us all out, then slowly start replacing ethernet with fiber. Scroll another 5-10 years, most have fiber in the cities and gigabit connections at very low prices.

It can be argued that the little guys (ISPs) got a little screwed especially those who haven't been bought, but overall the romanians got a really good internet and that's all that matters in the end.

The take away here is that once people started getting used to low-cost mostly local network + internet within a highly competitive environment, the "big" ISPs had no choice than to provide at least an equal service.

It's true, that was a different time, but now it's even better, because hardware is a lot faster and cheaper!

Granger's 'Light Table' was always an experiment in my mind, but I'm kind of sad that he dropped it and moved on to the next 'let's fix' programming thing.

Was it a dead-end?
