LPT You are rich enough to hire movers. They will be worth every penny.

Growing up an Army brat my family moved almost every 2 years on the dot. The gov covered those moves, and it was great sitting in a chair in your front lawn, and watching movers come in, pack everything into boxes, then load them all. It was not until I got much older that I realized that was not the norm with moving.

Hire.

When I moved from fancy downtown apartment and bought my house 4 years ago, hiring movers was the best decision I ever made. And I was able to find a company that charged by the item vs by the hour. They definitely had some hustle.

Lately, I've been hiring labor to help with the larger items.

For local moves like this, I really kind of prefer doing it gradually, a few small loads each weekend. Makes it easier for me to keep track of everything.

Insert ramble: Thought we were going to have to make "the decision" for our oldest dog yesterday. Thankfully he recovered and we get to pick him up today at lunch.

This... is damned interesting. It fundamentally challenges my understanding of network routing:
I honestly thought that was not physically possible.

Clearly I was wrong.

Why not? There's nothing special about net 10 or 192.168 addresses, routers can route them just fine. They are just reserved as not being loaded into the global routing tables so that individual sites can choose to use them however they wish.

Most likely the traceroute above is traversing one or more VPN tunnels that are invisible from the overlay network.

Also note that the address printed out by each stage of traceroute is simply the source address of the ICMP TTL expiry message generated by the routers along the chain. That doesn't actually have to be a routable address, in normal IP processing the router doesn't even look at the source address of a packet before making a forwarding packet. (security features like ACLs and unicast RPF can change this, but they may or may not be enabled on any particular path)

I honestly thought that 192.168.0.0/16 was genuinely non-routable.

Like, that there was something about the fundamental design of internet routers which would cause them to simply Gandalf any packets bearing that identification.

Now I know that this belief, which I have held firmly since the 1990s, is incorrect.

I do believe the tracert results. Those addresses, aside from the 192.168 one, are all part of the valid range of address spaces on this company's WAN.

How this started: We have several genuinely-isolated networks in the building, for truly broadcast-critical stuff that we don't want corporate IT touching.

All of those networks have at least one Windows machine on them which is dual-NICd, so that I can VNC into it and use it to see the equipment on the other side.

One such machine recently started complaining about an address conflict on the 192.168 side. This was puzzling to me. Since that machine's netmask (on the 192.168 side) happened to be 255.255.0.0 (I don't know why), I ran a full ping-sweep of all of 192.168.


And when I saw many, MANY 192.168 addresses which I didn't recognize, well, I was confused. It hadn't occurred to me that these would be visible to that machine, not through its private NIC, but through its connection to the WAN.

So the gear which is on the isolated side is fine, no conflicts there. But the machine was seeing a duplicate of one of them coming in through a connection which I'd never realized was capable of carrying said traffic.


So that's the fun new thing I learned today.

RFC 1812 ("router requirements") defines "martian addresses" that are not to be forwarded. In general that's packets where:

- source address is multicast or 0.0.0.0/8

- destined to 127.0.0.0/8 or 0.0.0.0/8

- destined to "class E" addresses (240.0.0.0/4) (these have been reserved for future use essentially forever)

These are also just conventions/standards though. I'm pretty sure at cisco we had hidden "nerd knob" CLIs to turn off the filters on each of them though, because there was at least one customer who had a non-conforming network and needed to allow those kinds of packets. None of them break anything fundamental.

My perception of "big" networking is, to some extent, tainted by the fact that my first big corporate job was at Harris.

Being a DARPA-involved defense contractor, Harris was one of those companies which scored an entire /8 address block all for itself. So, during the entire tenure of my employment there, literally every single device had an actual, real-world IP address.

Back then, DNS and NAT were for chumps. If I wanted to access the FTP server which I had running on a linux box in the in the lab, from my house, I just typed in the address.

That gives a man a sort of warped view of the landscape.

A lengthy but interesting watch:

Technically, Grindr is a Large Hardon Collider.

Up until a few days ago, if you had asked me "What is the sickest thing you can possibly imagine?" I would not have said "Posting a video of yourself online, in which you play with two kittens for a while, then put them into a vacuum storage bag, seal the bag, and use a household vacuum cleaner to pull all of the air out of the bag, crushing the kittens to death."


Mostly because my imagination would not have conjured up such a thing.


That having been said, the recent 3 part documentary series "Don't F**k with Cats" is a damned interesting (and, kind of disturbing) show to watch. I won't spoil it too much, I'll merely say that what I described above was not the worst thing which happens, and that a small group of internet vigilantes formed an online posse dedicated to discovering the identity and whereabouts of the Kitten Vacuumer.

I'd like to do vacuum "testing" on that guy indefinitely...
Take him down to just above the boiling point of blood and bring him back up just long enough to catch his breath and then back down again.
Lather, rinse, repeat.
I've got enough vacuum pumps that I could reach that level in a coffin shaped box in 15 seconds. 15 on, 45 off forever.
He'd feel like he'd die once ever single minute...

I saw that show a year ago, he was one sick puppy.
The posse kicked ASS!

That's a good way to do it.

I would concrete those people just above their knees and string them up just enough so they can't slump over. Then let the town people throw walnut sized rocks at them all day and night their they were buried. Remove rocks and repeat until they were dead.

Pretty sure that was a real thing people did back in the day.

Nor could mine, and now I'm left wishing I could go back and unread it. :cry: :sad2:

You'd do that....Without Remorse?

Following up on this post from a few years ago.

I now live in a house. Nobody above me, nobody below. The exterior walls are brick. Thick, heavy, load-bearing, "Archduke Franz Ferdinand of Austria is still alive" brick. This is a wholly new experience for me.

Over the weekend, I realized that I can now crank up Pomplamoose, Hipster, Gangstagrass, The Electronic String Orchestra, and, yes, even Frog Leap just as loud as I damned well please, late at night.

As a test, I put on Leo Moracchioli's Africa and turned the level up to a point verging on "uncomfortable." Then I put on some shoes and went outside.

At the side of the house directly outside the temporary office room (I'm still getting settled in and arranged), you could sort of tell that music was playing, barely. But you had to be standing right there to notice it. And there is absolutely no way in hell that the neighbors would hear it unless they had a window open and their head hanging outside.

So that gave me license to start acting like Jesse Pinkman.

Long story short: as inexpensive nearfield monitors go, these speakers are amazing. Virtually zero perceptible distortion (admittedly, while adjusting for the source material being compressed YouTube audio), no matter how hard I push them. The left one, which contains the amplifiers for both, started getting noticeably warm to the touch, but never complained.

I like these speakers. In fact, I've purchased a few more sets of the newer version of the exact same model for use in a couple of new post-production suites at the TV station. I'll probably buy yet another set when we build the new band recording studio next year.

More amps, more speakers..........if you aren't annoying your neighbors, it's not loud enough.

Remember that one time that an arms company decided "Hey, let's manufacture a 7.62mm rifle as a bolt-on attachment to a semi-autonomous robotic dog and sell it," and everyone was like "Yeah, that's a great idea, and the potential implications of this product existing are not utterly terrifying at all."
