You can't as far as I'm aware unless you control the entire batch during inference, or don't use batching which would require you to run your own inference.

When I read the paper I immediately wondered if this would work. Good to see that someone has tried it and indeed it does!

A creditor calling debt because you violated your covenants is not a rugpull. That's how creditors insure they can be paid back before you predictably run out of money.

So, essentially the system has a serious denial of service flaw. I wonder how many variations of flight plans can cause different but similar errors that also force a disconnect of primary and secondary systems.

Seems "reject individual flight plan" might be a better system response than "down hard to prevent corruption"

Bad assumption that a failure to interpret a plan is a serious coding error seems to be the root cause, but hard to say for sure.

Sierra space seems to be furthest along on this. Videos of their burst tests are pretty epic as well.

New comment by jmvoodoo in "Don't obsess over tax and legal structures"

This is very well thought out advice. That said you do need to be focused on the right areas of tax code, and understand that some things can be changed later and some things cannot (at least, not easily or without significant expense).

For example, I relocated to Puerto Rico several years ago and am taking advantage of a 50% transferrable R&D tax credit. Because it's transferrable I can sell the tax credit to people that have a tax liability even if I don't.

After fees, this means I get roughly 40% cash back on my R&D expense. This is a big deal to me and my company.

If you don't do your home work you can potentially miss out on some great opportunities. That said, you do still need to build a good business, or the best tax structure in the world won't save you.

Unrelated, but I read your book in the 90s as a teenager and it had a huge impact on my life. Still one of my favorite books. Thank you.

We have been using bullmq in production for just over a year. It is a piece of technology that our team doesn't have to think about, which is pretty much all I could ask for.

We did end up adding some additional generics which allows us to get strong typing between producers and consumers. That I think has been a key piece of making it easy to use and avoiding dumb mistakes.

One step we have taken is to build an auth system that requires you as the developer to explicitly specify the security of an endpoint using a decorator. If no decorator is provided, then the endpoint is completely locked down even to admins (effectively disabled).

If an endpoint is decorated with something that is considered dangerous (i.e. public access), that triggers additional review steps. In addition, the authentication forbids certain combinations of decorators and access patterns.

It's not perfect, but it has saved us a few times from securing endpoints incorrectly in code.

This actually seems reasonable, and a potential part of the narrative the original poster would be likely to leave out.

In this case "the service" would be to look the other way on illegal activities for $10k/mo.

I'm not saying cloudflare can't do it, I'm just saying it's wrong.

jmvoodoo — Sun, 26 May 2024 13:21:26 +0000

But for $10k a month cloudflare is ok with that? Either it's acceptable or it's not, there is no way that this looks good for cloudflare either way.

New comment by jmvoodoo in "Gigantic new aircraft design aims to create the largest plane ever to fly"

jmvoodoo — Sat, 23 Mar 2024 01:05:08 +0000

I actually know someone at radia and asked them this exact question last year. Apparently the blades are also extremely fragile and couldn't withstand the forces of being mounted on an aircraft. The problem with lighter than air is that the wind farms tend to be in places with, well, a lot of wind. Not ideal places for lighter than air vehicles.

Helicopters just aren't efficient enough, would have the same issues with wind (especially when carrying a giant airfoil), and would damage the blade if they came out even a bit out of formation.

You're right it doesn't make intuitive sense, but the people doing this are pretty damn smart and actually did think of these things!

Actually it looks like RSAs. I didn't even apparently know that RSUs were different as I've always received RSAs and thought they were the same thing (and in fact they had been called RSUs, but the structure looks like RSAs as defined here)

I am not an accountant or attorney, so you should do all of your own research. However any discussion or information about RSUs that doesn't mention an 83b election is at best incomplete.

I don't know anything about MRI machines, but couldn't they be built with high temperature superconductors and use liquid nitrogen? If anything this feels like a cost issue not a pure technology issue...

That's pretty much the entire point of many publications. You think readers of Financial Times aren't reading FT in the hopes of getting their own material gain? What about Wall St analysts? Consuming something for gain is not copyright infringement, distributing it for gain is.

New comment by jmvoodoo in "Fake Trees: Using Indents for Simpler UIs"

jmvoodoo — Sat, 30 Dec 2023 15:20:08 +0000

I started a company that dealt with a lot of tree like data. It is possible to transform your tree structure into an indented list in O(n) time. This used to be one of our interview questions at the time. There are a number of ways to store your data in various SQL databases that allow you to quickly get and render segments of the tree as well without recursive queries.

Once you understand those concepts, then storing your data correctly as trees has a ton of benefits over indenting like this.
