NUTS

[…]

But if there’s one thing I remember about Sim by, it’s his criticism of the Singaporean mindset.

The No U-Turn Syndrome, or NUTS, was how Sim viewed how Singaporeans always required a rule base to get anything done.

It’s referring to how in Singapore, u-turns are not allowed unless there’s a sign that allows you to do so, which is different from how other countries do it — you can u-turn unless there’s a sign prohibiting you to do so. And to make things even more fun, there are sometimes no u-turn signs, too.

This also means that when you want to do something, you automatically seek the approval of an higher authority, and if there’s no rule, the default is “no”.

It’s terrible, and forces you to just stay in your lane without making changes.

When I started working, I saw plenty of examples of how this worked, especially in larger organisations.

With the passing of Sim, it doesn’t hurt to be reminded of what he said again, and the examples he gave of how inflexible our Singaporean mindset is.

If we’re going to honour his legacy, we should honour his words, too. Because as nuts as it sounds, NUTS is still pretty relevant in our society today — if not more so than ever, with the challenges Singapore faces ahead.

Cryogenics

Eventually, the mortician was not pleased with the other bodies sitting around on beds of ice, so a LN Dewar capsule was secured for the remaining three. Another man was already frozen and sealed inside the capsule, so it was opened, and he was removed. Nelson and the mortician then spent the entire night figuring out how to jam four people — who may or may not have suffered thaw damage — into the capsule. The arrangement of bodies in different orientations was described as a “puzzle.” After finding an arrangement that worked, the resealed capsule was lowered into an underground vault at the cemetery. Nelson claimed to have refilled it sporadically for about a year before he stopped receiving money from the relatives. After a while, he let the bodies thaw out inside the capsule and left the whole thing festering in his vault.

Another group of three, including an eight-year-old girl, was packed into a second capsule in the Chatsworth vault. The LN system of this capsule subsequently failed without Nelson noticing. Upon checking one day, he saw that everyone inside had long thawed out. The fate of these ruined bodies is unclear, but they might have been refrozen for several more years.

Nelson froze a six-year-old boy in 1974. The capsule itself was well maintained by the boy’s father, but when it was opened, the boy’s body was found to be cracked. The cracking could have occurred if the body was frozen too quickly by the LN. The boy was then thawed, embalmed, and buried. Now that there was a vacancy, a different man was placed into the leftover capsule, but ten months had elapsed between his death and freezing, so his body was in rotten shape — no pun intended — from the get-go and was eventually thawed.

[…]

The worst fates of all occurred at a similar underground vault that stored bodies at a cemetery in Butler, New Jersey. The storage Dewar was poorly designed, with uninsulated pipes. This led to a series of incidents, at least one of which was failure of the vacuum jacket insulating the inside. The bodies in the container partially thawed, moved, and then froze again — stuck to the capsule like a child’s tongue to a cold lamp post. Eventually the bodies had to be entirely thawed to unstick, then re-frozen and put back in. A year later, the Dewar failed again, and the bodies decomposed into “a plug of fluids” in the bottom of the capsule. The decision was finally made to thaw the entire contraption, scrape out the remains, and bury them. The men who performed this unfortunate task had to wear a breathing apparatus.

Bucha

Again, sadly unable to embed it here — but definitely worth looking in the investigational journalism and the war crimes committed.

Mounting a whole disk with partitions

I reinstalled one of my RPis (moving from 32 to 64 bit).

Before doing the full reinstall, I took a dump (dd) of my disk.

Usually, I create one per partition, but this was the Christmas season, and I was half occupied with feasting and half occupied with entertaining Ila. So, mistakes were made.

I ran dd if=/dev/sdb of=backup.img — but this means I can’t mount the disk directly, as it’s not a partition:

# mount backup.img /tmp/disk
mount: /tmp/disk: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.

I should’ve dd’d /dev/sdb2 instead of the entire disk.

All right, so let’s figure out what can be done… First, let’s look at the content of the image:

# fdisk -l backup.img
Disk backup.img: 111.8 GiB, 120040980480 bytes, 234455040 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x8297a463

Device          Boot  Start      End  Sectors  Size Id Type
backup.img1 *      8192   532479   524288  256M  c W95 FAT32 (LBA)
backup.img2      532480 34078199 33545720   16G 83 Linux

So, we can probably mount starting from sector 532480.

We can see that the sector size is 512 (which, I think, is the default for most). So, if we multiply 512 * 532480 we get 272629760.

Now we can mount the disk using the following command:

mount -o loop,offset=272629760 backup.img /tmp/disk

And that should do it.

The 2nd partition (the one with data) is now mounted and accessible under /tmp/disk.

If you need the first partition, the same can be done by running 512 * 8192 = 4194304; the following command mounts the boot partition:

mount -o loop,offset=4194304 backup.img /tmp/disk.
