I have an implementation of nested coroutines for C in this file: https://github.com/billziss-gh/winfuse/blob/master/src/winfu... This uses the macros coro_block to introduce a new coroutine block,

Any comparisons of Mermaid vs other tools? Why do you like Mermaid? I use Plantuml myself and I find that I regularly have to fight with the layout engine to get diagrams to looks the way I want them too.

This looks nice and I certainly appreciate the battery life. To the people that are excited because this is outside some regulatory limits. A few years ago there were no or few drone regulations and people abused this; the result was strict

I was curious, so I dug out the watch. It is a Glycine Airman 2000. See here for a review from 1999: https://www.timezone.com/2002/09/17/the-glycine-airman-2000-... EDIT: A couple of differences from the watc

Agree. The Garmin MARQ Aviator is beautiful. They just need to make a solar version that does not require charging and then I am a buyer.

Interesting. So would a mechanical watch be ok, but an electronic one not ok?

by billziss 7y ago
Good catch! From the Garmin MARQ Aviator page: > Smartwatch mode: Up to 12 days > GPS mode: Up to 28 hours > GPS with Music: Up to 9 hours > UltraTrac™ mode: Up to 48 hours

I think this likely has to do more with individual habits rather than anything else. But I find that watches that I do not use all the time are more likely not to be ready to be used when I need them. For example, I have an old Suunto Ambit

Zulu time where I mostly fly is 8 hours off local time. If the watch is a regular 12 hour watch you have to do a mental calculation for time and as a pilot you learn that the less mental calculations the better, when a lot of things are hap

I am no fighter pilot, but I (used to) fly airplanes, floatplanes and helicopters. A watch with a 12 day battery life makes little sense to me as I find it too easy to forget to charge it. Even if you put it on a checklist, it may be too la

Thank you. This looks exactly like what I had in mind. EDIT: Another alternative would be to be able to slide the main screen halfway to the side thus allowing a second screen next to it for a dual screen setup.

by billziss 7y ago
Just wrote something similar. I agree.

I would much prefer it if manufacturers created a multi-screen setup with screens next to each other. I can imagine some form of folding or attachment mechanism that converts a single screen laptop to dual or triple screen. Since going &quo

I use the refcount to avoid copying the string when passing it around. I just refcount it instead. To clarify this is part of a larger library that includes other memory management machinery, such as autorelease pools, etc.

These days my work is focused on kernel/systems programming, so plain C (char or wchar_t) strings outside the kernel, and whatever the kernel requires inside it (e.g. UNICODE_STRING on Windows). When I do apps I have my own length-pref

by billziss 7y ago
I do not think I have ever seen a string that needs more than 64K, but then again I do not read whole files in memory in C. (I do in Python.) So this would be wasteful in many cases. My personal variant uses 32-bits for length and 32-bits f

by billziss 7y ago
While I often implement strings along the lines you suggest I disagree that this feature belongs in the standard library. For one thing how big (sizeof) should the length prefix be? 16-bits? 32-bits? 64-bits? The beauty of the C string is t

> But that would require them to implement a new file system from scratch wouldn't it? VolFs in WSL1 relied on NTFS to do the heavy lifting. You are correct.

Perhaps you are right, but to me this feels more like Microsoft hedging their bets, rather than a genuine interest in having two parallel products doing effectively the same thing (from a user perspective). I asked the same question on thei

I think I agree with your overall understanding. It would be interesting to learn what FSF's position is regarding WSL2.

Which systems do you think are more similar: Windows and Linux or FreeBSD and Linux? Presenting a Linux syscall interface on top of Windows is a hard task. The systems have fundamentally different approaches to many OS functionalities. In g

Yes, I am aware of the Linux emulation in FreeBSD and elsewhere.

Although many people seem to be receiving the WSL2 news well, I am one of the few that feels that we will be missing something important with this new direction. WSL1 was pushing the boundaries of OS research: - a method for having multiple

WinSpd is not a standalone application, but rather a set of libraries and components that allows others to create applications that can do what you want (serve a disk over a network). The included sample, called rawdisk, memory maps a file

I think it is a perfectly legitimate question. I had two reasons for creating this: a practical one and a theoretical one. The practical one is that I wanted to be able to store disk data in a cloud storage bucket (i.e. "format" a

Thanks for the additional information :)

Sorry for the second reply, but I read a bit about ImDisk. I think the main difference is that WinSpd is a general tool for creating disks as user mode processes, whereas ImDisk is a tool for mounting image files only. It looks like WinSpd

by billziss 8y ago
Interesting. I was not aware of ImDisk. Reading about it, it appears to be a RAMDisk only tool. Did I misunderstand?
