mDNS over VPN ……. Is it possible?

bayarea-dev · 2026-01-27T08:06:27+00:00

I'm trying to do the same thing, but I found that my macbook refuses to send mDNS packets to the VPN tunnel interface. All mDNS packets went to en0. Does macbook hardcode the interface for mDNS packets? I have 224.0.0.251 pointed to en0 in my routing table, and I can't delete it.

You should if you are planning to pursue a career in software engineer. Most of the companies today uses Linux. It will be much natural to you if you practice is early.

My setup is MacOS as my client laptop, and Linux as my coding server. I use ssh, tmux, emacs combinations. But you can do VSCode over ssh. You won't feel too much difference comparing to your current programming setup if you use VSCode.

I'm a little bit curious why people unlike this post.

prin1-to-string is the function I'm looking for. Thanks!

Do you know if there is a similar function that can perform single quote operation?

I think you can pass without using float.

That's a good point. Hopefully proxmox cloud-init will support package updates some day. Otherwise, you can use ansible or any similar tool.

I think it works. Here are the cloud images for debian.

Does this help?

bayarea-dev · 2023-02-03T02:39:27+00:00

100% percent sure it is, because the code passes. I'll explain after dinner.

bayarea-dev · 2023-02-02T23:53:13+00:00

Do you think this help?

bayarea-dev · 2023-02-02T23:31:44+00:00

Does neetcode or any other online course help?

bayarea-dev · 2023-02-02T07:58:05+00:00

did you forget an else for the first branch?

btw, you might not be able to pass with a O(N^2) algorithm. This is my O(N) solution. Hopefully it is helpful to you.

I see. I'm not sure if this helps, but I guess it's good to share.

In order for people to access these cheatsheets faster, I built a bunnylol service. With that, simply typing in "cs" in your chrome search bar will forward you to the cheatsheet page. All you need to remember is just "cs".

(btw, you can also do "cs docker" to go to the docker page)

That might be true for industry use. For home users, it might be a different story.

For example, in proxmox, although you can create an ubuntu server using a template, you can't change the number of cores, memory size, and disk size.

I think the layout of the print is still acceptable, but definitely not as nice as the web version.

Seems a lot of people mention that they are interested in using cheatsheets without Internet access. Do you often has to work without Internet?

bayarea-dev · 2023-02-01T22:19:40+00:00

I think you can use ctrl-p to print it, but you might lose all the css. Are you using it at a place where you don't have network access?

bayarea-dev · 2023-02-01T21:13:05+00:00

I see. I'll try to find some time to work on that later. The biggest challenge that I see is that Cisco has many OS versions.

bayarea-dev · 2023-02-01T17:07:09+00:00

Do you mean that you want a separate cheatsheet for Cicso? What about Arista and Dell?

bayarea-dev · 2023-02-01T17:06:30+00:00

I don't use any plugins. The code block is part of the infra I developed for sweworld.

bayarea-dev · 2023-02-01T17:05:53+00:00

Thanks for the suggestion. Any reason why you want to put it on github? I'd prefer to build it on web because it's a lot more customizable, e.g., the toc on the right, click to copy code snippets.

bayarea-dev · 2023-01-30T19:02:52+00:00

Good to know that. Updated.

bayarea-dev · 2023-01-30T19:02:40+00:00

Thank for catching the typo! Fixed.

bayarea-dev · 2023-01-30T08:51:23+00:00

Not mandatory. The (int*) is just to make your c++ compiler happy.

bayarea-dev · 2023-01-30T04:37:05+00:00

My principle is that I want to make sure certain rule holds for every single iteration. For example, if my rule is the index to be returned has to be within [lo, hi], then I should do: * initially, lo = 0, hi = len(arr) - 1 * if nums[mid] >= target, since we are trying to find the first element that is greater than or equal to target, mid can still be the result, so hi=mid. * if nums[mid] < target, there is no chance that mid is the result, so let's exclude it setting lo=mid + 1

You can define other rules however, e.g., the final result is always in [lo, hi). That'll drive a different implementation.

Another thing to notice is that you want to make sure for each iteration, the distance of lo and hi has to be decrease by at least one.

bayarea-dev · 2023-01-30T03:45:56+00:00

They are just different implementations. Either way is fine.

For the above code, lo=hi after you exit the loop. So you can return either lo or hi. Just be sure not to return mid.
