I think it makes more sense to return an empty array

// invalid input return null or throw an error
if (!setA || !setB) {
    return null;
}
if (!setA.length || !setB.length) {
    return []; 
}
// or do nothing since the for loop will not trigger anyway

Can we remove the first of these tutorials? seems like both of them are tutorials for the same blockchain. And the second one links back to the first.

I was not able to find any instructions on where to put the keys.prod file.
Someone in discord told me it goes into ~/.local/share/yuzu/keys/
That folder was not even created by yuzu.

I feel like the folder should be created by yuzu at runtime and that there should be instructions on where to put the keys.prod file in the first place.

I was using build 20200324-2e484ccc7 for this.

SPY GAME: Write a function that takes in a list of integers and returns True if it contains 007 in order.

For this one, the entire solution is wrong because what is asked in question is a number that appears continuously 007 but in actual case its showing True for 50307 and also for53007. There must be some modification done to the solution.

Is it possible to have LINUX container（LXC,LXD) compiled into OpenWRT?
The LXDUI is a project allows users to manage LXC in a Web UI.
If you have these 2 enabled in OpenWrt, that would be fatastic.

Before we have a good fix for #63 we should manually verify the qemu args somehow. We may have to copy-paste code from qemu or something. In the very least we should be aware of incompatible config options exposed in the UI (maybe we can't check additional args).

Credit goes to Javier Honduvilla Coto for find this: http://hondu.co/blog/open-and-python
I contacted him by email to clarify a few bits, and thought it'd be a nice addition here.

f = open('/tmp/a', 'w'); open(f.fileno()) # OK
open(open('/tmp/b', 'w').fileno())        # KO

White Paper:

p10 could use a couple of short sentences of introduction. It may be well known in the community what exactly goes into a threat model section, but the White Paper will probably be getting quite a bit of attention even beyond the tighter security community, and it might be good to explain that this section lists the capabilities various potential adversaries are assumed to have.
