I'm interested in the idea of building rigid high strength frames, for example for a lathe or milling machine frame, by burning out shapes in plate steel on a CNC plasma cutter, then assembling those plates with 3d printed support jigs holding them together and bolting through them with long bolts. Then pour the interior with concrete and after the concrete sets up, tension the bolts to prestress the concrete...
It's a bit limited in shape, you can't really include the type of features you see in cast iron, but machine bases typically don't need them that much.
When you're attaching a component to the base which needs precise orientation, you attach it to a jig which holds it true, then you bring the bed up to it and you epoxy the mating surfaces so the epoxy acts as a shim. After the epoxy hardens you can tension the hold-down bolts.
I realize that there's a general purpose way to make a high precision surface on something:
1. Lay a piece of surface ground steel, maybe 3-5mm thick, down on a surface plate. This steel must have a smooth finish but it does NOT need to be precise in any way.
2. Tape around the perimeter of the steel with vacuum tape and attach a vacuum hose on one corner.
3. Start the vacuum pump, sucking out all of the air between the steel and the surface plate. At this point, the vacuum will flex the steel, making it conform to the surface plate.
4. Take any old rigid piece of steel, stone, or concrete, paint it with epoxy, and stick it to the exposed surface of the steel.
5. After the epoxy hardens, release the vacuum and cut the tape free.
At this point, you have a high precision surface that has been twinned to the surface plate. The epoxy has hardened in the form of a "perfect shim" between the rigid body of the part, and the strip or plate of steel.
Problem with the above is you don't know how uneven the part is that you're sticking to, too uneven and there's not enough epoxy to fill the gap and you get a void.
A related concern is if too much epoxy is painted in places to fill up the voids, the thick areas will be subject to more shrinkage than the thin areas. Epoxy glues shrink by 0.1 - 3% depending on the type.
Two thoughts come to mind:
1. This process can be done using tinfoil, and then you can hit it with a wire brush to scrape out all of the voids since unbacked tinfoil will tear out instantly. Then the process can be repeated again with a little bit of extra epoxy painted in the void areas. When the entire surface comes up with no voids, then you do the final mating with sheet metal.
2. A related idea is to pour concrete down against the sheet metal on the surface plate. This will have more uniform shrinkage so voids should be less of an issue.
In the flooring business, they use a very liquid cement that is self-leveling, they dam it up and then pour it in, and then it will naturally level to perfectly flat and even.
That could be replicated into something else by just using a very watery epoxy. Something with a very low surface tension.
That'll work for making something like a table, but when we're talking about precision, things get "weird"...
The thickness of a human hair is about 2 thousandths of an inch. Paper is 4 thousandths, a laboratory grade surface plate is guaranteed flat and true to 0.045 thousandths.
When you get to these precision levels, you can put a 1/2 inch piece of steel under a measuring instrument and watch it flex as you push it lightly with your finger. You can hold a part in your hand and see it expand from your body heat in real time. Pouring even the thinnest epoxy and letting it cure in air might get you down to 1 thousandth, but you can get that by purchasing a piece of bar stock and making a simple surface grinder.
Surface plates are made on very high precision surface grinders, those grinders are themselves made using master surface plates. The masters are made in groups of 3, they coat them with a die called Prussian Blue, this die creates an extremely thin and uniform coating of about 0.01 thousandths. They lay one plate down on top of the other and this transfers blue marks from one to the other, then they scrape it using a tool which can take off around 0.001 thousandth per pass. They use 3 because when 1 and 2 match, and 2 and 3 match, and 1 and 3 match, then they know the surfaces are actually flat...
So I would say if you want to build precision machines, the easiest thing to do is buy your surface plate and then make everything else by cloning it.
Off topic: A surface grinder is actually quite easy to make, you clone a surface plate twice, once for the bed and once for the carriage. The carriage slides on a film of oil over the bed and you just use rudimentary chains, tracks and screws to control the right/left and forward/back because these are not precise. Also the angle of the head is not precise, everything can be eyeballed.
A surface grinder is the most rudimentary machine, it requires only 1 flat surface.
A lathe requires 4 flat surfaces: 1. Vertical ways (up-down truing) 2. Horizontal ways (back-forth truing) 3. Vertical cross-slide - parallel to horizontal ways 4. Horizontal cross-slide - square to vertical ways Then the headstock needs to be parallel to horizontal and vertical ways.
The milling machine is the worst, because it has all of the surfaces of the lathe, but it also has a Z surface which needs to be trued on two axes.
Fortunately the lathe and mill are not generally expected to produce work better than +- 1 thousandth, but the cylindrical grinder and the EDM have all of the same problems as the lathe and mill, but are held to a much higher standard...
I've been thinking about this, I have two possible solutions: 1. Air bearings which are obviously self-cleaning 2. Oil bearings with an oil pump which forces a continuous stream of fresh (filtered) oil into the bearings and sweeps away dust
Air bearings have really good precision, but they're expensive to buy commercially and not that easy to make, so I tend to lean toward #2, but I don't know how much oil flow you can push without it beginning to lift the carriage up off of the ways...
I imagine somebody has studied this because it seems weird not to...
I think it goes without saying that you'd like to have grinding in a room with lower air pressure than the machining room, but even grinders have surfaces, so there's still a problem that needs to be addressed...

Iran’s President Masoud Pezeshkian suffered minor injuries in an Israeli air strike on a meeting of the Supreme National Security Council in Tehran on June 15, a senior Iranian official said.
The assassination attempt targeted the heads of the three branches of government in an effort to overthrow it, said the official, speaking on condition of anonymity.
The strike was carried out shortly before noon during a meeting attended by the heads of the executive, legislative, and judicial branches of the government along with other senior officials.
The semiofficial Fars news agency also reported new details on the assassination attempt during Israel’s 12-day war with #Iran, which was first announced by the Iranian president in an interview released on Monday.
The session was taking place in the lower level of a government facility in western #Tehran when the attack started, Fars reported. The building’s entrances and exits were hit by six missiles to block escape routes and cut off air flow.
Electricity was severed following the explosions, but Iranian officials managed to escape through a pre-designated emergency hatch, including the president, who is said to have sustained minor leg injuries while evacuating. aljazeera.com/news/2025/7/13/i… #IsraelTerroristState #imperialism #war

@Catweazle interesting article, I wasn't aware of a lot of that. Is it possible to run a live session on a mobile phone the same way you can on a desktop?
@davetortoise, I've never had done it in a phone. Andisearch said
Yes, it's possible to run different operating systems on mobile phones through virtualization and emulation, though with some limitations:
For Android phones: - Ubuntu Touch can be installed directly on compatible Android devices like the Google Pixel 3a/3a XL and Fairphone 4[^1] - Linux distributions like postmarketOS, Mobian, and Manjaro ARM can run on specific phone models[^11] - Windows 10/11 can be virtualized using QEMU, though performance is very slow and not practical for daily use[^19]
For newer Android 13+ phones: - Windows 11 ARM can run in a virtual machine thanks to improved virtualization support[^13] - According to developer Danny Lin, who demonstrated Windows 11 running on a Pixel 6: "Windows 11 as a VM on Pixel 6" is possible through Android 13's standardized virtualization system[^13]
For running Android within Android: - VMOS allows running a virtual Android environment inside your primary Android system, complete with Play Store access and root capabilities[^24]
The key limitations are: - Device compatibility is restricted to specific phone models - Performance may be significantly slower than native OS - Not all hardware features and peripherals are supported - Installation can be complex and may require technical knowledge

Hi, I recently finished setting up my Asustor NAS, and I found the snapshotting setup in it a bit confusing, so I'm writing this as a quick reference that might be hopefully useful to others.
For context, my device is a AS1102TL, and it's running ADM 4.3.3, but I imagine it should apply to all recent Asustor devices.
First of all, the reason I picked Asustor instead of e.g. Synology... it's because it was not clear if the latter actually supported LUKS full disk encryption on an external usb hd. In Asustor you have to ssh into your NAS, but you can definitely do it.
The only gotcha: If you created the LUKS volume recently on another system, it's likely that it'll be using Argon2 for key stretching. A memory-intensive algorithm, for which the 1GB of memory provided by my AS1102TL is not enough. The solution is simply to add another key with a different algo, e.g. PBKDF2, or just create the volume on your Asustor. Either way, you're going to be able to read and write it both from the NAS and another Linux on your pc.
$ sudo $(which cryptsetup) luksOpen /dev/sdb1 encrypted # "encrypted" is just the name that I gave to the device, pick anything... remember the `-S` flag if you need to select a key in a different slot
$ sudo mount /dev/mapper/encrypted /mnt/USB1
... do what you want ...
$ sudo umount /mnt/USB1/
$ sudo $(which cryptsetup) luksClose encrypted
Unfortunately, this doesn't mean that once mounted, the disk will be integrated in the ADM ui (you're not going to be able to see it in the "External Devices" ui, nor be able to select it as a destination in the "Backup & Restore" ui).
Normally, mounted external drives are available on paths like /share/USB0, /share/USB1. Maybe it could be possible to mount (or symlink your mount point for) your disk there, to make it usable to ADM, but by default /share is an immutable loop mount of /volume0/.@system/sharebase.loop
$ lsattr -d /share/
-----i------- /share/
Trying to workaround that with chattr and maybe manually modifying sharebase.loop felt a bit more risky than needed, so I didn't attempt that (the ADM ui doesn't provide a btrfs send functionality, so it's not very interesting for our purposes anyhow).
Now, you have two different approaches to accomplish incremental backups of btrfs snapshots, one where you just create them yourself from the CLI, and one where you can try to reuse the snapshots created in ADM.
I'm using the same naming convention, and same location that is used for snapshots created by ADM (you wouldn't get conflicts anyhow, unless you're creating another one in the exact same minute).
I recommend the -v verbose flag for btrfs receive, otherwise you're not going to see progress while the operation is ongoing.
That's it! Of course, the first send will have to happen without specifying a parent with -p, to do a full clone.
Reuse snapshots created in ADM
There are two problems with this: the snapshots created by ADM are not read-only and they are mounted right under the toplevel.
To address these issues:
sudo mount /dev/md1 -o subvol=/ /mnt/rootvol
sudo btrfs property set /mnt/rootvol/v2025079-2324/ ro true
then pick a parent snapshot, and send the incremental changes:
As above, use the -p and -v flags as needed. That's it!
If you're wondering why did we have to mount the / subvol, you can try without:
You can mount the snapshots directly in ADM's Snapshot Center, by toggling the Preview toggle for a snapshot. In that case, they are still going to be RW, though mounted as RO. You can deal with that by remounting: sudo mount -o remount,rw /volume1/.@snapshots/v2025079-2324/ && sudo btrfs property set /volume1/.@snapshots/v2025079-2324/ ro true,
You can then try to send the changes, but what you're going to get is:
$ sudo btrfs send -p /volume1/.@snapshots/v2025079-0824/ /volume1/.@snapshots/v2025079-2324
ERROR: not on mount point: /volume1/.@snapshots/v2025079-2324
The error is a bit confusing (you have mounted the volume! why is that not good enough?), but you can get a bit of clarity with btrfs subvolume list.
$ sudo btrfs subvolume list /volume1 -qua

as you can see, the snapshots created in ADM are directly under top level 5 and if you list them under /volume1 (which is just the mount point for the /base subvolume), they are not found directly underneath (despite them being mounted there), which is why you see them being under their own <FS_TREE>.
Conversely, the ones that you can create directly from the cli under volume1, appear as top level 256 and they are under /base if you list the subvolumes under /mnt/rootvol.
PS, while I was closing the dozens of tabs that I opened to investigate how everything fits together, a note on what I wrote earlier:
this doesn’t mean that once mounted, the disk will be integrated in the ADM ui (you’re not going to be able to see it in the “External Devices” ui, nor be able to select it as a destination in the “Backup & Restore” ui).
mounting the disk on a path already accessible by ADM file explorer doesn't work because of permission issues, similar to the immutable flag that you can see with lsattr... but someone on Reddit had another workaround:
I mounted the opened device to another path already accessible by ADM file explorer. I don't think it will matter where really. But in my case I made two partitions on an external USB drive. The first partition is a small exFat formatted (10GB). The second partition takes up the rest of the drive and is formatted with cryptsetup (LUKS). Finally, to use this I open the LUKS device and mount it to a location in the first partition (which is automatically mounted by ADM)
