Double dequer sort In this challenge Bubbler describes sorting a list by inserting its elements left to right into a double ended queue or "deque". Take a number from the front of the array, and push it into one of the two ends of the deque. Repeat this until the array is empty. That challenge ...

@SandboxPosts until now I've never wondered how deque is pronounced...

Rydwolf Programs

it's not day-quay-eee?

RubenVerg

i've always said it like "deck"

but now that i think about it it's probably wrong

nevermind, i'm right

deque

dequeue Shortened from double-ended queue. IPA(key): /dɛk/ Rhymes: -ɛk Homophone: deck deque (plural deques) (computing) A linear data structure in which elements may be appended to or removed from either end. Coordinate terms: list, stack, queue deque on Wikipedia.Wikipedia Borrowed from English deck. Rhymes: (Brazil) -ɛki, (Portugal) -ɛkɨ Hyphenation: de‧que deque m (plural deques) (nautical) deck (floorlike covering on a ship) Synonym: convés (computing) deque

Crowd Strike is the company that might be responsible

I was wondering why it seemed to take a while for other countries' news sources to pick up on it but then I realised that y'all are waking up to this while it's an afternoon affair here

Reports of outages started 3 hours ago

@emanresuA I mean, they kinda sorta have to say that

Given that they're a government organisation

Themoonisacheese

08:50

Definitely caused by crowdstrike

according to HN:
This was apparently caused by a faulty "channel file"[0], which is presumably some kind of configuration database that the software uses to identify malware.

So there wasn't any new kernel driver deployed, the existing kernel driver just doesn't fail gracefully.

(i can't open shitter on corporate wifi so idk what the tweet says)

lyxal

> There is a faulty channel file, so not quite an update.

There is a workaround...
1. Boot Windows into Safe Mode or WRE.
2. Go to C:\Windows\System32\drivers\CrowdStrike
3. Locate and delete file matching "C-00000291*.sys"
4. Boot normally.

Does Windows 11 Home have CrowdStrike installed on it?

Themoonisacheese

not by default no

crowdstrike is a corporate antivirus solution that you have to installs on PCs in your organisation if you want to do business with the united states basically

The Empty String Photographer

My windows computer should be fine then

Themoonisacheese

09:04

oh yeah

most computers worldwide are fine, it's just that apparently microsoft uses it on the cloud services so that's down as well

either that or they're having really bad luck because azure is also down

Neil

reminds me of a similar outage caused by a certain brand of a/v software which mistakenly identified a core windows process as a virus, but killing it causes a bsod or reboot or both

Themoonisacheese

sounds like comodo

The Empty String Photographer

Just opened my windows device and there seem to be no issues

Themoonisacheese

well, do you use crowdstrike to begin with?

The Empty String Photographer

No

And that, my friends, is why you should never use a Windows phone.

I have two points with a vector direction each. How do I connect them with a series of arcs such that the arcs have maximum radius?

Something like this

You can also use line segments if nececairy

Basically, given two tangent points, find two circles that share a tangent

Themoonisacheese

tha'ts much clearer

don't 2 circles on a plane always share a tangent?

unless they intersect, i guess

no even if they intersect, i tihnk the only way this doesn't work is if one circle is completely inside the other

mousetail

Hmmm that's true

Themoonisacheese

i should point out that i am not good at math

so grain of salt etc

mousetail

I'm pretty sure you are correct. Though I'd still need to find the maximum radius

Themoonisacheese

infinite?

make both circles as big as you want, as long as they're the same size they'll never encapsulate each other

mousetail

12:37

If you do that you'll basically create almost full circles that wrap back around

Themoonisacheese

there's some leeway that somehow depends on the arragement of your inital vectors, either circle can be an amount bigger than the other, but i don't think thhere's a numerical maximum, maybe simply a rational one

mousetail

You are right, it would be possible. Ideally I'd want the arc angle limited to 180 degrees but that seems like it would make the problem much harder

Themoonisacheese

(as in c1 can be 30% bigger than c2, it's probably a more complex function though)

@mousetail in this sceenario, can you choose the initial direction of the arc or is it always forward wrt to the vector?

mousetail

It has to be forward

Themoonisacheese

then i'm pretty sure the hard part is figuring out if there is a solution, but if there is then the maximum is once again infinity

like, either a shared tangent exists, in which case the original problem apllies again, or it doesn't.

mousetail

12:44

I'm think you can construct a scenario where there is a small arc angle solution upto a certain radius then it "overshoots" and then the only solution is nearly 360 degrees

Themoonisacheese

you're right yes

okay yes you're right that this is much much harder with 180 degrees arcs

are the vectors always pointing in opposite directions? or is the direction pretty much random?

mousetail

Pretty much random. sometimes they directly face eachother and you can just draw a line

Themoonisacheese

right, basically 0 radius

there's only a subset of all angles between them such that there exists a solution, half of it is infinite, the other has an optimal solution where the 2 arcs are touching, i think

mousetail

That sounds right, though I can't verify it

Themoonisacheese

13:04

actually

is it allowed to start drawing an arc no towards the other point?

like so: imgur.com/e1isxZY

if this is allowed then still inifinite, trivially

regardless thanks for the nerd snipe today is very slow

mousetail

14:18

@Themoonisacheese It should eventually connect

mousetail

14:40

Anyway this is waht I'm doing with arcs

Themoonisacheese

14:52

@mousetail right, but if you start your arc away from the other point then there's always a tangent that exists a long as a solution exists, with infinite radius

mousetail

You mean essentially breaking up one long arc into many smaller ones such that each is less than 180 degrees?

But what kind of winning criterion is this, for robbers?
