Status report

It all started a few weeks back when a friend gave me a couple of "surplus" laptops They were part of a bunch that had been retired by a company he does tech support for.

Anyway, one had a virgin (re)install of Win 10 on it, and I played around a bit. It was designed to hook up to a docking station which had some nice extra. And they were cheap on e-bay. So I bought one. And when it arrived, I hooked it up to the monitors and keyboard/mouse on the kitchen table I use as a workbench.

This meant [personal profile] fayanora and I could resume our long lapsed weekly TV nights. We are way behand (watching shows from 2021 now) but we are making a dent in the backlog. Good thing because space was getting aa bit tight on the server.

Utility woes

Specifically, computer utilities. I've been doing some long needed cleanup on my ridiculously large collection of images and the like.

This mostly consists of two things. First, checking to see if the source sites (various tuimblr accounts at the moment) are still up, and if there is any content I don't have.

The utility I used to use for that quit working some years back. and no updates or word from the author. Since I needed to do something about this, I finally got around for looking for a replacement. Found one. WF Download. Works even better than the old one did. There is the small issue that it uses a different (and arguably better) naming scheme for the downloaded files.

Which brings us to the *second* issue. Checking for duplicate files in the downloads. Now, way back in the 80s there was a program named Unique Filer. It had the concept of "base folder" and "compare folder". So it could compare all the files in the base (and its subfolders if you wished) against all the files in the compare (again, including subfolders if you wished).

Now it presented a list of the matching files. and you could wade thru them one by one. *or* you could tell it to nuke all the file in the compare folder that matched files in the base folder. Zip done.

It quit working with Windows 7. Maybe because it was very old or maybe because it was a 16 bit program (originally written for Windows 3) and I'm running the 64 bit version of Win 7. In any case no longer workee.

What I use now is Duplicate File Finder, It lets you compare files in a folder or folders and present a list of dupes. Each and every one of which has to be individually deleted...
[delete][enter][down][down] (repeat ad naseum)

*why* has the concept of "base" and "compare" folders been lost?

Anomalous technology

This was sparked by watching a remastered copy of and old BBS civil defense videos. Basically about what to do before and after a nuclear attack.

It got me thinking about the stuff I read back in the 70s and 80s about building fallout shelters, and other "how to survive getting nuked" stuff.

So I considered survivors of an attack, and what they might maintain in the generations after (assuming moderate collapse of civilization here).

Now, deliberately built fallout shelters are useful for other things as well. Storm shelters, "panic room" type refuges, etc. And the food and water stockpiles are a good idea for pretty much any sort of disaster. So, those could survive thru generations.

Other things, like improvised air filtering and air circulation are a bit harder to maintain, but far from impossible. and they are again useful for other situations (bad or long lasting dust storms, or persistent smoke from wildfires for example.

It's even possible to build radiation detectors with some pretty low tec. And radios are harder, but given some knowledge & resources, they could persist for a long time. Crystal sets are very simple, and you can use chips or transistors from "dead" electronics as the crystal. Transmitters are harder, but still a lot more doable than you might think.

So you could have a "primitive" looking society with lots of hidden and fairly sturdy shelters, bigger stockpiles than you might expect and some unexpected emergency communications. Won't that set the cat among the canaries for "more advanced" raiders.

This also reminded me of a bit that used to come up on the Traveller SFRPG mailing list.

Sure, the planet is primitive, but it does have a spaceport (even if it's just a cleared hunk of land and somebody with a radio).

If it gets many visitors, odds are somebody will have put up some sort of satellite network. In Traveller, you can literally toss some cheap stock satellites out an airlock and they'll self position and organize into a network.

This means comms. Even if only for the convenience of off-worlders visiting and prospecting. Not that much harder to have the satellites do weather monitoring and the like.

Receivers are common, and cheap (think android cell phone). So natives *will* manage to get them. Maybe at first, just so they can get weather info and contact other villages in an emergency.

Some bright boy (either an off-worlder or perhaps an "enlightened" native in government) will bring in receivers for "school by satellite) like India and other places have. This too will help.

But even at this point to your typical off-worlder, the place will look the same on the surface.

*Under* the surface, things are different.

Picture Bwana and his friends who've hired a "native guide for a safari. Or to help them explore for minerals.

They'll be impressed by how well the guide knows the country and what keen eye for the weather he has. He'll be snickering to himself when he checks the weather photos and GPS, as well as aerial shots of the terrain ahead. No need to worry the off worlders with details they don't need to know.

:ikewise imported weapons (in small numbers at first) and imported vehicles. In some ways like the third world here, in other ways different because the tech level was higher when things started getting introduced.

This sort of thing can make for fun stories or fun gaming sessions.

Help!

Trying to access my DW mail/comments gets a "Are you human" test that is in an infinite loop.

I get the same thing if I go to the DW homepage. So I can't even figure out how to *report* the problem!

Bad design

Since it's going to be cool today, I turned off the AC. I also decided to clean the filters since it's been a while.

Ok, washed the filters, waited for them to dry. Went to put them back. All okay so far.

Put the top cover back on. Note, the covers are different sizes and gave these helpful arrows on one side to tell you which way is up.

Top cover went one fine. Bottom cover just wouldn't go. It was getting painful crouching next to the AC (It's a portable).

So I dragged over a milk crate to sit on. Cue many more minutes of trying to make it go into place.

Finally, I decided to try something stupid. I turned the cover upside down (so the arrow was pointing down).

It slid right in.

I am *very* annoyed with whoever designed this....

Radio Free Luna

Radio Free Luna is a concept I've seen in several stories and at least one filk song.

Basically, a radio station broadcasting from the moon and doing programming that some places on Earth might not approve of. For example at the moment, actual reporting on the war in the Ukraine beamed at Russia.

Simple enough concept. The biggie being having folks on the moon long term who aren't all that dependent on Earth and it not being worth the effort to stop them.

But I'm wondering about the practicalities. Power is easy enough large solar arrays and lots of storage for he night.

Antennas are another matter. Anybody have suggestions? Would beam antennas on nearside/farside boundaries be better? Or would some sort of centrally located antenna?

I'm thinking short wave or maybe even AM or FM bands. Just not sure what would be the best combo for both reaching more radios and best penetrating the ionisphere.

At least you can build *big* on Luna. Full wave dipoles anyone? :-)

Hides, bolt holes, lairs, etc

OK, I've been thinking about the subject recently. I decided to start by defining some terms/types.

Hide: outdoors, provides concealment, but not cover. Think of a hunting blind, but designed to fool humans too.

????: like a hide, but also provides cover (ie stops weapons and other attacks to at least some extent. Foxholes, dugouts and improvised bunkers are good examples

Priest's hole: a "room" that provides concealment for one or two people. Intended to hide them from a non-destructive search. Think "hidden closet". Very much a temporary thing (hours, not days)

Panic room: Often concealed, but mainly intended to protect from a destructive search and from attacks of various sorts until help arrives.

Bolt holes are similar to panic rooms, but usually have a concealed entrance to something that takes you to a room(s) elsewhere.

Then we start getting into tornado cellars, bomb shelters, fallout shelters, bunkers and lairs.

In these you've got increasing levels of protection from various threats (sometimes specific threats only, other times from a variety of threats). You also have increasing occupancy times, and the need to accomadate multiple people.

Anybody see anything wrong here? Maybe a different way to break things down? Or categories I've overlooked?

Once we've refined this, thewn I can start to work on what things ae needed for the various types.

silly (?) idea

A "badge" that has a swinging needle meter (or a bar graph LED) labeled "SPOONS".

Either have a hidden knob to adjust the reading, or mauybe find a sensor that semi-reliably tracks your spoon level.

ETA
One labeled "STRESS" would be good too. and likely easy to rig a sensor for. :-)

Special costuming effects I'd like to see.

All of these are based on Vantablack like materials.

Best would be if we could make "cloth" that acted like vantablack. Zentai suit would effectively be "living shadows". Flowing robe type stuff would give "cloud of darkness"

Less ambitious would be a full face "mask" (say something like a fencing mask) worn with a hooded robe. Tiony holes would let enough light in so you could see well enough to move around. But anybody looking into the hood's opening would just see utter blackness.

That last is probably doable.

Finally, ig we could come up with a coating that'd work (and be safe) on scleral lenses (like contacts, but they cover the entire front of the eyball) you'd have the effect of utter blackness instead of eyes. It'd look like there was just a hole in space where your eyballs should be.

Be *really* spooky if you could do it.

computer driving me nuts

Been working on [personal profile] fayanora's desktop for the last few weeks.

Current problem is that it suddenly decided that it *won't* work with dual monitors. Or rather, it won't display images properly on anything connected to the HDMI or DVI connectors on the motherboard.

And often won';t display proper images on the VGA monitor either if another monitor is connected. driving me nuts.

lousy interfaces

The Storage company I deal with has a website you can make payments thru. Or rather, it has one you *used* to be able to make them thru. It hasn't worked for several months at this point.

I made a payment over the phone last month. Did it by talking to the manager.

This month I got hit with a phone menu. A horrible one.

I had to enter my credit card number using the phone keypad. Yeah, 16 digits with no possibility of erasing if you mistype. You doi get prompted for confirmation that you entered it right. Except the audio keeps fading in and out, so I had to reenter it because I missed a prompt. Then you enter the card expiration date. Then the zip code pof the address the card is associated with. then the security code.

All this on a tiny keypad on the phone.

Remember that beeping?

A while back I posted about how I woke up to my computer beeping at me. Couldn't find a reason, so I shut it down. Restarted and the beeping was back.
So I wound up setting up a new-to-me computer and moving stuff to that.

Yesterday the beeping started again. Which was really annoying because all that the old & new systems had in common were the hard drives. Shut it down and switched to the Linux box that I still need to get some things set up on (getting it to recognize the NAS servers, mostly).

After an hour or two, I started it up again. I got a couple beeps then they stopped. When it finished booting the desktop only had only the wastebasket icon on it. And a program was complaining about not being able to find something on drive G: Which was the external eSATA drive.

At which point I turned off the external drive and restarted it. Windows recognized it and the icons were back.

Later when the beeping started again I carefully moved the external drive close to my ear. And *it* was the source of the beeps.

Arrrgghh.

I'll dig into things more later, but at least now I know where the problem is. Might be heat problems (though the drive case isn't that warm) might be the drive failing, dunno. But at least I know where to look

Not a supercomputer but...

I finally fund something that actually puts on load on this thing.

I've got a program called Similarity that compare image and audio files and shows you which ones are similar (and how similar). Very useful for weeding out duplicates, near duppes, and stuff like the same image at different sizes or mirrored, etc

Still generate a fair number of false positives, but it's still a *major* help.

But when I compare some of the larger directory trees the CPU usage hits 100% (yet I can still do other things without noticeable slow-downs). The fans also spin up a *lot* and it gets kinda loud.

But I took about an hour to work on 82,000 files. Then I took an hour or so going thru the 1100 potential dupes. When I was done I only had 600 files left, most of which were things like photo sequences where someone had taken a pic every few secs or faster) so moving thru the list gave me a sort of slide so in the part of the display that showed the current image.

Hitting the down arrow fairly quickly moved along fast enough but still let me spot things that needed to be checked out

And toggling between the up and down arrows gives a nice way to compare the images visually. The parts that are the same stay steady and the parts that aren't sort of "blink".

Earthquake resistance.

In the various Polychrome Heroics threads, They've had a number of stories dealing with the aftereffects of "The Big One" (a megaquake hitting the west coast of the Us in the alternate world of Terramagne)

Recent posts by [personal profile] dialecticdreamer triggered an odder than usual train of thought. I thought it be of interest to many folks, not just the ones writing in that universe.

First thought was having a building on some sort of ball bearings or something on top of a sturdy foundation. That the ground shimmy all it wants and the building mostly sits there as the ground moves under it.

Fun idea and *wonderful* image but has just a *few* practical problems. :-)

So ok, we need to damp the movement a bit. Magnets in the foundation and the bottom of the building? Likely have problems.

But that got me thinking about the anti-sway dampers they put in tall buildings. Those involve massive springs and weights. Also they way they mount stuff inside Cheyenne Mountain. Ok, that may be workable.

Probably need to have a "basement" and flexible pipes and cables for water, sewer, gas, electric and other connections to the building. You need a space to goive the flexible pipes/cable *room* to flex so they don't kink up.

Probably put the springs and weights down there in in areas where they don't interfer with the connections.

Not a *detailed* solution, but something that may be doable with a little testing and research.

Added bonus, worst case after the quake, you can disconnect the building from the base and rig some sort of cradle and *move* it to a new location, because it'd have to be built to be "self supporting" in ways current buildings aren't

Computer woes

Well, it's a good thing I'm in the process of transferring to the new computer.

At 3 am I was awakened by a beeping noise. It turned out to be the main computer. No pattern to it. Just [beep[ [pause] [beep] [pause]....

I tried figuring out what the problem was, but windows didn't any error messages I could find. Nor were things like various temps out of range.

A few thing didn't work, and so I started closing windows to shut down. but some wouldn't respond. So I had to do a "force shutdown". And *that* was on the "shutting down" screen so long I finally just held down the power switch.

Powering back on it immediately started the beeps again and said something about the configuration not matching. Couldn't get into the setup, so I powered off.

Currently copying contents of the drive from the old to the new (plugging old drive into a spare slot).

Currently working on the one new drive that has been delivered.

Then I'll have to see if I can fit enough from the 500 gig C: drive from the old one onto the 300 gig C: drive on the new one to get things working acceptably.

If not I'll try running the new box off the C: drive from the old box until the new drives arrive.

Once I get the new box completely setup up[ with the new drives, I can put the old box on the bench and see what's hosed.

new system (update)

I stuck a couple of spare drives in the Dell Precision T3500. Took a while to get it to boot (the monitor on the workbench does not like the video signal that the vid card puts out when you are in BIOS settings.)

Once I got it to boot, it took a fair bit of time updating windows (the drive hard Win 7 Pro on it, but fort very different hardware). Fortunately the case had a product key sticker on it, so after an initial complaint of a non-verified install, I managed to make Ms happy.

it performs scarily well. Of course, with a 6-core Xeon and 24 gig of RAM it *should*.

After checking prices, I decided to order new drives for it. A new BD-rw drive, a pair of 500 gig drives and a 2 TB drive.

They should all be here within a week. Of course, the 500 gig drives are going to be the last to arrive.

I can install the BD drive and the 2TB drive before then and get a head start on moving stuff over from the old system.

I'll do a fresh install of Win7 on the 500 TB (drive C:) and set one form of backup to use the other 500 gig drive (d:) to back that up.

The I get to set other sorts of backup to the NAS servers.

Oh yeah, I didn't realize one set of SATA cables went uner the motherboard to the other side, so it "only" has 6 SATA channels. One of which is the eSATA connector on the back of the motherboard. That still leaves 5, of which there's only room for 4 in the case (unless I want to put an SSD in the 3.5 "floppy" bay) Eventually I'll dig up another SATA to eSATA adapter. And put that in. Or not.

Struggling along on the old box while doing various things on the new one to clean up various things that the old one couldn't really handle.

PC rebuild

Firefox has been getting to be more and more of a pain over the last few updates. It's finally gotten intolerable.

Also, Beyond Compare is using unreasonable amounts of RAM (I've seen it over 3 gig, and this is only an 8 gig system!)

So I've bitten the bullet. I got a new to me system a few months back that I was going to use for something else, but instead I'm going to use it to replace this system. It's got 24 gig of RAM and a quad core (or maybe hexcore) CPU. Also has 5 internal SATA connectors and one eSATA connector.

It's going to be a pain because I'll have to move a bunch of hardware over. BD-R drive, 3 HDs, and maybe some other things.

Hopefully the performance will improve to usable again.

Bluetooth idea

I've got some cheap BT speakers. They are cylinders about half as tall as a can of soup or veggies. The top is a speaker, and there's a mic on one side. So they can be used with a phone as a speaker-phone.

I've got a much better BT speaker now, but I got to thinking that if I could link to a BT device I could use the old ones as an intercom of sorts. Like for example hidden in some Halloween decorations.

Seems like overkill to tie up an entire computer for this. Anybody know if there's a gizmo/box I could use for this?

The tale of a power strip

The other morning (way-too-dark-thirty) I realized my CPAP had stopped. I rolled over and the clock was off too. But the room lights were on.

Ok, not a power outage. I crawled over to where I could reach things and the clock & CPAP started up again. I tried to check the plugs and they all seemed to be ok.

A while later, it happened again. This time I managed to get to where I could see things without things coming back on. A notable item was the the power switch for the strip was lit up. So the *strip* was getting power...

But as soon as I messed with it, things came back on. *sigh*

This happened several more times throughout the early morning. I just tried to deal.

Finally, when things went out again I heard a distinct "bzzap!" noise. Something was arcing. This is very much not a good thing.

So I wound up unplugging everything from the strip and unplugging it from the wall. I searched my stock of spare cords, etc, but didn't see another power strip.

Arrgh,, that meant waiting until Albertsons opened at 6am and hoping they had some in stock.

Then I remember that I had another power strip plugged into the outlet at the foot of the bed for use if I moved some things over to this side of the room.

After more fun contortions, I managed to get it out and plugged in in place of the arcing one.

Hours later I took apart the bad strip. Only thing I found was a dust bunny a bit smaller than the cotton bud on a Q-tip, but a lot less substantial. It was sitting between the black and white wires on the power switch. There were a couple of black dots wjhere it was almost touching the wires.

That appears to be what was the problem, but I just finished disassembling the power strip and tossed the pieces in the trash. Didn't want to tempt anyone to retrieve and use it.

That was a very strange incident. I'm surprised that the dust bunny could carry enough current to cause the power to the outlets to fail, but not enough to catch fire.

The gods of electricity are weird.
