Yeah I've worked a lot with this and was also curious as the thermo distribution is just one part, you also have a lot of short range forces that explode if you increase the timestep by too much and I didn't see any tricks around

You, sir, made me laugh!

They are a very common design-pattern in traditional C, as you kind of emulate object-oriented virtual function overloading by using them in structs. I don't think it's realistic to avoid them just by principle.. As in network ser

In Django it's literally a matter of adding 5 lines of code to enable the redis cache. The complexity is in actually setting up the Redis server, but this can also be trivial in many cases.

Yes, it's not something you typically think about when writing code even if you're security-conscious. IMO it's not good that the double-free bug has these consequences.
636.
by l33tman 7y ago
The double-free bug means that a double-free of a chunk of size X might lead to subsequent allocs of that size X to return the same pointer. The lib in question parses the GIF twice. In the first run, it allocs an internal info struct of si

Well on a related matter I've been searching for years for a Linux implementation of the bog standard terminal window on my Macbook, that persists scrollback and history for all open tabs during reboots etc. Such an enormously usable t

The docker containers are the least complicated bit in production deploys. Orchestrating all the up/down-scaling and releasing, binding of IP-numbers, DNSes etc.. that's where the potential "lock-in" comes (although I wo

It's not a good comparision, AWS charges this to lock AWS users into their ecosystem. It's free from the internet into AWS and extremely expensive out to the internet. This is of course by design to make sure you can't ha

The EU's GDPR already requires opt-in for all auxiliary tracking etc. even for those huge policies. So you can try to hide all the nasty stuff in a long policy, but you are not allowed to default to them. A single "I agree" b

Long ago I used to joke that perl is write-only... was that harsh or realistic? (I still believe it - too clever constructions which feel smart at the time you come up with them :)

We've used it for years as well, and (for us) the absolutely worst fact about it is that it is a memory hog like crazy. Even without any accesses at all, it needs like 32 GB RAM on our nodes, for a 0.5 TB DB (with a bunch of indexes).

I directly found a completely wrong description of the Heisenberg uncertainty relation and stopped reading after that. But yes, the underlying research probably has some interesting stuff!

It gets biased because a single positive feeling is enough to get the human mind to think there is a causal connection between the pill and the "cure". There are hundreds of variants of the common cold virus, and you are at any ti

You're correct, particle physics or QFT is not needed to appreciate the fundamental QM "mysteries", any non-trivial evolving measurable observable will do.

by l33tman 8y ago
This is not a correct description at all of QM complementary observables. This is a purely classical explanation (and was one of the first layman "explanations" back in 1920, but that was 100 years ago and QM is much better unders

But can you specify spot instance pricing for Fargate containers? I don't think you could last I checked. Spot instances are 0.25x the cost of normal EC2 instances often, so ECS with Spot launch configs are super-cheap.

This is not true, on the released FDR data, it shows clearly that the pilot flying corrected the MCAS system's trim down adjustments at every cycle (each 10 seconds) for most of the level flight. So at least the PF must have been aware

Django's ORM has always served me well, it handles migrations and I've had almost zero SQL-hacks that needed to be done.

I never noticed this actually :) But we mainly tested and ran this in Europe and not in the US, maybe there is a difference in how the front plates are mounted. I don't think I can recall any European plate I've seen that is mount

Yeah that would certainly be interesting. At least it would work to expand a dataset. I guess the tricky part is to realize at all that some problem cases can appear though, and code them into the simulation.. for example, the bumper-bent l

23andme only searches for known snips (SNPs, single nucleotide polymorphisms), they don't scan the genome, that is still a fairly costly and slow procedure (although it's radically getting cheaper and cheaper!). https:/&#x2F

Apparently it's bad if done at cruise (due to the small margins in thin air) but if done in mid-air it's controllable. See this episode of Mentour Pilot: https://youtu.be/OguKthkuaT4

Interestingly, some airplane types allow the use of thrust-reversal in flight, notably some fighter jets. It's apparently used when you do need to sink quickly..

The perfect orbit geodesic is infinitely thin and therefore unstable due to quantum mechanics. So even if a photon is injected at the perfect orbit it would not stay there, it would fall in or eject. Besides, even without invoking QM, any o
