proctor··on What If We Haven’t Met Aliens yet Because They’ve Messed Up Their Planets Too?
reminds me of the "Kurzgesagt – In a Nutshell" youtube video "Why Alien Life Would be our Doom - The Great Filter"[0] that discusses many of the same ideas!

proctor··on Dstat project ended due to RedHat replacing it with its own dstat tool
this strongly reminds me of the hn post from five days back in which the main thread talked at some length about a very similar scenario

proctor··on Radioactive Hulk of Carrier USS Independence Found Off San Francisco (2015)
this reminds me of the documentary "the fog of war"[0] in which robert macnamara talks about the conventional type bombing of japan's cities with firebombs before using any atom bomb.

proctor··on Ethiopian Airlines 737 MAX Investigation Preliminary Report
the fact that the combined strength of two humans would not be enough to _break_ the manual trim system does not tell us whether that combined strength would be enough to _turn_ the trim wheels at all.

https://news.ycombinator.com/item?id=19575318 "option 2)" (on this same page) refers to a situation where a "dive" could be executed in a situation where manual strength is not enough to trim the aircraft.

and the recent snc-lavalin case in canada[0]

[...Quebec Premier François Legault said that SNC-Lavalin was one of ten publicly-traded companies headquartered in Quebec that the province considers to be "strategic" and therefore in need of protection from a takeover that would force the company to leave the province....]

proctor··on Ethiopian Airlines 737 MAX Investigation Preliminary Report
this video[0] from "mentour pilot" on youtube explains the stabilizer system quite well.

it seems the trim wheels are connected manually to the trim mechanism in the back, but when the trim stabilizers are in an extreme position the wind loading on them makes it very hard/impossible to rotate the trim wheels manually.

from what i understand, one way to relieve/lessen the wind loading so that the manual wheels can be used again is to (in the case of trim down) dive the plane. this would lessen the wind loading on the stabilizer and allow the manual wheels to move again. but you would need "room" to dive, something they did not have in this case.

proctor··on Knoppix 8.5.0 Released
the difference that i find valuable is that cloop is not a file system, whereas squashfs is. this means that i can use cloop to compress _any_ file system at the block level. very useful as a sys-admin.
proctor··on Knoppix 8.5.0 Released
the cloop[0] system from knoppix is something i use often to back up arbitrary file systems. debian has the cloop-utils which includes create_compressed_fs, and this is great for making compressed copies of file systems which can then be read without uncompressing the whole blob. however i have found debian's cloop-src module to be problematic in that i have never been able to get it to compile. the actual module comes as source only, and without this part it is not possible to read the backups without uncompressing, which is a shame. in fact it appears debian has recently removed cloop from debian testing[1] for this reason. so it is still necessary (and enjoyable) to have knoppix around to use the decompression system, although it is a huge pain to do it this way. i hope debian is able to get things sorted finally with cloop-src! that would be great.

proctor··on Kdenlive: an open-source video editor
what about cinerella? when i researched what video editor to learn next after kdenlive it was cinerella. it seems to work fine, and i am surprised not to see any comments regarding it. seems like it is completely out of the running?
proctor··on Audio AI: isolating vocals from stereo music using Convolutional Neural Networks
this sounds interesting. could you elaborate a bit? it is unclear if you are inverting once, or twice. "if you have a stereo signal, anything not fully-centered will come through better while the rest is cut out" -- is this before or after an inversion?
proctor··on Can you use a magnifying glass and moonlight to light a fire? (2016)

proctor··on WebSDR – Shortwave Radio on the Internet
maybe not specifically relevant to your use case, but one excellent open source program for ham radio sdr stuff that i have found is linrad. it's got a bit of a learning curve, and is pretty fun once you get the hang of it. the author is very interesting, and has a youtube channel with lots of info on linrad and other ham radio projects.

Here's the opinion of an engineer who is also a drone and fixed wing flyer, Bruce Simpson of the x-jet youtube channel:

He thinks that larger organizations such as amazon want the airspace and are lobbying for it.

proctor··on Don't Get Your Coworker to Agree with You
> I've read a bunch of negotiation books as well as conversation books.

i would like to read some good books on negotiation and conversation. do you have any advice on what the best books that you read on the topics were?

proctor··on TP-Link firmware sends six DNS requests and one NTP query every 5 seconds
Also, I maintain a page[0] that lists the top routers with support for openWrt and DD-wrt.

proctor··on SSH vs. OpenVPN for Tunneling
Does anyone have any experience with ipop/groupvpn[0]? It seems like an interesting alternative to tinc in that it can do turn/stun using libjingle to bust nat. I'm not clear on how well tested or secure it is though.

proctor··on SSH vs. OpenVPN for Tunneling
tinc 1.1pre seems pretty good, but I do worry about the legacy fallback for encryption; There doesn't seem to be any way to e.g. --force-experimental to prevent encryption falling back to the old RSA mode.
proctor··on “It's been great to see Wireguard mature over the years”
Have you tried ipop/social-vpn[0]? It uses libjingle (stun, turn, etc) to get through firewalls. I don't know much about it's security though, or if it has been audited.

proctor··on Crack WPA/WPA2 Wi-Fi Routers with Aircrack-Ng and Hashcat
I tested some of the most popular Kali Linux compatible cards against each other here[0]. Note that there is a version 2 of the popular and cheap TP-Link TL-WN722N which DOES NOT work like the version 1 and should be avoided.

All of these cards are "known to just work" on linux at least.

proctor··on Gold coins found in Netherlands from last days of Roman Empire
The Tesoro Compadre[0] is pretty great and very affordable.

Best in higher end might be Nokta[1] and its sister company Makro[2].

Anything from any of those three companies will be good and high value.

proctor··on Next Iteration of “The Rust Programming Language” Book
I have found this book to be an excellent resource. Also I have been supplementing it with the oreilly book "Programming Rust" (early release at this point) which has also been great. http://shop.oreilly.com/product/0636920040385.do I have had very little experience with C style languages in the past and am mostly scripting until recently.

Thanks for your suggestion! What filters would you like to see there? I have had some comments also along the lines of it being not obvious enough what the "sort" buttons do; Do you think the page is to "bare bones?"

As for the C2600, I do not believe it is stable yet, and still being worked on. I deliberately don't put "trunk" only builds on the page because not everyone is sufficiently technical to deal with them. It should show up soon though by the looks of things (will be stable soon-ish).
