and users have correctly
Are they Russians or Russia's supporters? You checked it?
because this is not on topic for Hacker News
This is top news about military high-tech development and use.
Its exactly an HN topic. Stop filtering news by personal bias.
Is this newsworthy though?
Absolutely.[0]

«Strengthening Europe's Civilian and Military Preparedness and Readiness» (by Sauli Niinistö), Chapter 02, Page 47:
The EU must be able to support Member States in the provision of citizens’ basic needs (e.g. food, water, housing and shelter, protection, health and sanitation), as well as ensure the continuity of its essential services and functions, such as the Single Market, public order and security, energy, transport, telecommunications and digital services, border management, economic and financial management, and satellite-based services.

Jakub Dvorský tweeted (quoting Amanita Design tweet):
buy our games and help Ukrainians survive another winter under horrendous Russian aggression![0]
> The invaded Ukraine is facing yet another harsh winter. Let’s help them survive! Buy any of our games[1] or DLC between now and December 20, 9:00 CET and we will donate all of our proceeds to People in Need[2,3]
NOTE: If you would like to directly donate to Ukraine needs there is a list of all possible ways to support.[4]

Just updated article on Wikipedia.[0]
let me know if it can be improved on in some fashion.
Might be good to replace rattleCAD link in the list from official site to Wikipeda article, where there are many rattleCAD related links already collected, including a link to old opensource versions on Internet Archive.
One I've found recently is Brent Curry's Linkage
Correction: Gergely Kovacs' Linkage (Brent Curry is dev of BikeCAD)
No, I mean Brent Curry's Linkage
Correction: Gergely Kovacs' Linkage (Brent Curry is dev of BikeCAD)
I've used this to draft (and build) a couple of frames.
If You still has files of some old versions of rattleCAD backuped, and it is not listed on Internet Archive[0] yet, please share it.
A while back, I put together a list of bike-oriented software at:
Nice list. It yet complete, but has somes software I've not seen before, such as "Bike-Draw".[0]
One I've found recently is Brent Curry's Linkage[1] bike design app, which looks like a serious competitor for BikeCAD and rattleCAD.
And there are few other not listed in your list SaaS for bike design, I've listed in previous comment.[2]
Also, I'm trying to create own bike design template/macro for FreeCAD.[3,4]
N.B. Reymon Reyes' Bike Builder app (bike parts cost calculator) on your list is not available on Google Play anymore, but its APK could be found on other sites.[5]

If you like Linkage, you might also like Solvespace.
No, I mean Brent Curry's Linkage[1] bicycle design software, not David Rector's Linkage Mechanism Designer and Simulator[2].
You should read Wikipedia article.[0]
N.B. About SolveSpace, as I'm its experienced user[youtube,patreon], I may say next: yes, it could be used for bike mockup, as any other CAD, but it still has a lot of limitations and even does not export correct STEP files yet[3], and in FreeCAD such STEP could fixed only partially.[video]
So, for serious 3D CAD work I highly recommend use FreeCAD (and LibreCAD for 2D CAD work) instead of SolveSpace, and use SolveSpace only as a helper tool like a calc or as a notepad for noting ideas.
About Linkage Mechanism Designer and Simulator, it is only useful for planar (2D) kinematics analyze, and if You are looking an alternative for it take a look on Pyslvs[4], that is in part based on SolveSpace's solver.

On GrabCAD there is a free 3D model of Frame Jig tool[0] made by author of rattleCAD.[img]
Today this would be a SaaS application
It exists for years, and rattleCAD has been inspired by it — its name is BikeCAD (it also available as a standalone app). Also, rattleCAD has been inspired by Linkage app.
Read Wikipedia article.[0]
Also there are freeware no-login SaaS: BikeGeoCalc[1] and BikeConfig[2].

Since the OSS version was posted I think it's good to note the author's updated version even if it's no longer OSS.
To be clear, in the description on Internet Archive page all this info exists, including active link to "new official site" and a link to Wikipedia article, I've wrote, where all the story of rattleCAD development has been described in details.
RattleCAD is parametric 2D CAD package
Yes, but since rattleCAD 3.4.05 there is an addon which generates a FreeCAD Macro.[0,1,img1,img2]
If execute resulted FreeCAD Macro in FreeCAD app, 3D model of frame (for rattleCAD Free) or full assembly (rattleCAD Privat/Professional) would be generated inside FreeCAD.[img3]
Sadly, I can't find this addon in rattleCAD 3.x source backups, but it distributed with rattleCAD 4.x releases.
Guess, it might be possible to recreate such macro if look inside rattleCAD source and XML-files that rattleCAD 3.x saves projects data in.

Wow, thanks!
Next month it would be the 100th Anniversary of ХВЗ manufacturing.[0]
There is a good playlist on 'Oleg AC' YouTube-channel, with many video reiews of all existed variants of ХВЗ bicycles and some other vintage bicycles and in private collections and musuems.[1,2]
There is might be more videos highlighting ХВЗ on his channel be added commemorated to 100th Anniversary.
ХВЗ plant still continue producing bikes with self made frames, jigs and aluminium rims, and using all the rest parts from Shimano and China. But, sadly till the end of 2021 it planned to relocate to suburban of Kharkiv.[3]
All old factory buildings[4,5] in urban area of Kharkiv has been sold, demolished and replaced with residential and office buildings in last years.[3]
P.S. Also there are two forums, with a lot of info about ХВЗ and discussions by its owners.[6,7]
N.B. I'm Ukrainian living in Ukraine.

There is a thread on Ukrainian cyclists' forum where collected decals of many variants of bicycle "Ukraine" and other bicycles built at Kharkiv Bicycle Plant (ukr. "ХВЗ" aka HVZ or KhVZ).[0]
There are also photos of rare bicycle "Ukraine" variant built in 1990s with decals in Ukrainian and English.[1]
