Just to clear up a common point of confusion: the "Robin Hood" scheme that is commonly used these days is not a multiple hashing solution like the original research paper from the 1980s (and Cuckoo hash table). What's used

Nice writeup, and most of this isn't specific to C#, but applies to native code (or Java) as well. These are typical misconceptions of people who have not studied concurrecy. What is specific to C# (applies to Java too) is having an im

I know Orbiter and I have been using textures from Celestia add-ons. They are typically normal rectangular textures with the usual distortion. Thanks for the pointer.

Yeah, this is what I figured. However, being a one man hobby project, I doubt I'll even get a foot between the door. Even finding the contact information for the different data sets would be next to impossible. I have considered enroll

This is great! I'm working on a space simulation project and I've been looking for imagery from space probes (e.g. New Horizons' Pluto and Charon imagery, Dawn's shots of Ceres and MESSENGER's new Mercury images). I

Yes, F1 race car composite parts are still largely made by hand (assisted by laser cutters, 3d printers and other high tech). The ability to produce prototypes isn't limited by the availability of raw materials. That said, an improveme

I like the fact that my vimrc is easy to deploy on new machines without having to hassle with plugins. At one point in the past, I did have a bunch of plugins (nerdtree, fugitive, surround, nerdcommenter, etc, etc) but they weren't tha

I had it at one point and it was decent (but not great), but I no longer use it. I always prefer using tags files to do code navigation instead of browsing files. With `:set wildmenu` (enabled in sensible.vim), using `:tabnew :edit :split`

by exDM69 10y ago
My advice: don't go wild with plugins or vimrc hacks. Get sensible.vim for sensible defaults and work with that. Vanilla vim is good enough for most editing and coding needs.

Note the scale. The "huge jump" is from 8.3 to 8.7 uR/h, just a few percent.

`git filter-branch` is a tool intended to remove sensitive material from git history. It requires a force push, of course. If the keys/passwords are already pushed to GitHub or other public hostin, they should also be revoked.

So they can focus on space exploration instead of web site maintenance? I understand why they use YouTube for video hosting (video hosting is difficult and expensive) and have a prescence on social media (to reach a wider audience), but yea

This only works if you stick to a simple filesystem, not crypto, RAID, etc. Otherwise you'll need to have file system utilities (lvm2, mdadm, cryptsetup, zfsprogrs, etc) on the initrd to get your rootfs mounted.

by exDM69 10y ago
Yes, it's a fun exercise to build a tiny Linux install that's fully on the initrd. Not that you'd want to have that kind of system in daily use outside of special applications. > I think it's even possible to embed th

The purpose of the initrd to have the initrd bootstrap to rootfs. This involves userspace tools like mdadm, lvm2, cryptsetup, zfsprogs, etc. It's not very common to need kernel modules (drivers) on initrd on typical hardware.

Something like this has been my default way of installing Linux for years - and I've installed Debian, Ubuntu (with debootstrap), Gentoo and Arch this way. Typically I just create another partition to my LVM volume group, chroot and in

It works very well but is still work in progress. I appreciate that it's "just an editor" and not a half-assed IDE or an application framework. But I think they might have taken it a step too far.

Thanks for the pointer. I am getting more and more frustrated with Vim (and neovim is not what I am looking for) and looking for alternatives. I did try "vis" a while ago and it was alright but not quite there yet. And it was a bi

I would recommend against starting with someone else's pimped out configs and go with something more conservative. Tim Pope's sensible.vim is a good starting point. It has "sensible defaults" but no opinionated keyboard

It was hogging about 60% of one CPU core (Skylake i7) on my PC. Seems like it's re-drawing the screen at 60 fps even though nothing is happening. Should be an easy fix.

The problem with the WebGpu proposal is that it is difficult to implement with Vulkan efficiently as the spec is now. I'm sure the spec can still be changed to be a better fit, though.
864.
by exDM69 10y ago
I am going to respectfully disagree with you here. Yes, Vulkan is a difficult API to work with and it's not at all beginner friendly. But simplicity and ease of use should not be guiding the decisions, the emphasis should be on providi

I understood that Lychee contains a chemical that prevents the body from "burning" fat and protein. This would be bad for diabetics as low glucose levels can't be helped by burning fat. And it's the opposite what dieters

Yes, but that's in addition to the dozens of proprietary boot procedures commonly used by Android tablets and smartphones and other ARM devices.

If it's all their code, yes they can do it (it might be a lot of engineering, though). But it might contain 3rd party code or dependencies to something that's non trivial to port to 64 bits. If you go look at the boot procedure of

by exDM69 10y ago
Yes, it would be a smart move if they can actually drop the 32 bit mode from the CPU/SoC but I wouldn't be so sure about that. Having the 32 bit mode may still be required for the firmware/bootloader/OS early boot enviro

Yes, I play KSP and Orbiter. In my study project, I learned thoroughly how to solve different two body problems (initial value, boundary value, closest approach) and wrote a C library [0] that's got all the orbital mechanics code you n

I've done this, learning advanced orbital mechanics on my spare time. But I manage to put in 1-3 hours a week, about one week per month at most and it's been almost half a year since the last time I was able to put my mind into it
