More on Metadata

This has been passed around for a while now, and it’s fascinating.

A certain cyber spook who shall remain nameless at this juncture told me about this sort of data analysis many years ago. It was just one or two little sentences along the lines of, “You would be AMAZED at the sort of things “they” can find out about you.” As I say; that was many years ago, and orders of magnitude in increased capability have been achieved since. As a merchant having done installment sales for more than a decade at that time, I had a database of my own, consisting of thousands of accounts, and immediately could see the power of what on the surface would seem like rather mundane and mostly useless points of information.

BUT, when you ask the right questions, and can sort by multiple data fields, WOW! We used it to make buying decisions, which were extremely important and had to done months in advance of peak selling seasons, and so it involved recent history and long term trends. It was also extremely useful in predicting patterns and indicators of contract violations. If I told you half of that stuff I’d be branded a scumbag, a bigot and a general son of a bitch. Its one and only purpose though was to avoid going bankrupt– You make the wrong decisions and you’re stuck with major inventory you can’t pay for, or you get it out the door and don’t get paid for it, and so you can’t pay for it.

So yes; we profiled in a very big way, you could say. At one time the default rate was so bad that we required a credit check of every prospective customer, but with analysis of a large enough database were able to do far better by asking for only a few simple bits of information.

Learning important things doesn’t need to come from positive data either. That is to say, what isn’t there can be as useful as what is there, when forming the kinds of association tables in the link, or plotting behavior patterns. For example; knowing those times when someone is unaccounted for (enter the Smart Grid, to know when someone is not at home), when compared to certain events, over time, can tell you a whole lot.

So I now wonder what a look at the metadata in the time and place of Jesus (arguably one of the most influential people in human civilization) would show. How about Bedford Falls of “It’s a Wonderful Life” (thoughbeit a fictional town)? In that story, you could say that Clarence showed George Bailey where he fit in the metadata analysis.

The Soviets, using infiltrators, both of the overt and the covert kind, were able to come up with their various arrest and kill lists in much the same manner.

That brings us to another issue, that being the concept of the inception i.e. a planted idea– The tiny seed of an idea that can germinate in the minds of people, multiply and grow into something large. The looks into associations in the link are all very interesting, but being able to predict or pinpoint inception sources is also very interesting.

Reading about the various groups and group associations in the link got me to thinking about the modern version of the 1700s pub. You’re looking at it. Sort of, but it’s much more open to the world.

I was also struck by the modern lack of such clubs and associations. We’re a much more fragmented society. We don’t meet with our neighbors much at all anymore, whereas it used to be common. We often don’t know anything about them.

But your government sure as hell can find out.

And I submit that this is by design. It’s either by the design of mere mindsets, which will reflexively respond in predictable ways, or by some mastermind scheme. I say it’s a combination of both, each nourished by the other.

Call it a leap into Crazyland if you like (I’ll be quick to say I told you so, later) but looking at the data points over my lifetime, things make a lot more sense if one assumes that our government is in a full-on war against the ideals and principles, the foundation of the U.S. and has been for decades. When other people are saying “W. T. F.!???” and getting all exasperated and confused, I’m saying, “Well sure. It fits perfectly don’t you know.”

Try it. Ask yourself what institutions, traditions and associations would be under attack or already under control if our own government were at war against the American founding principles and the American economy. What groups would be funded worldwide, which ones given a pass, and what groups would be targeted for degradation, intimidation or destruction. What industries would be targeted for nationalization? Yup. Gotcha. On all counts.

So accept it. Then you won’t be surprised or confused anymore. The specific organization of this war isn’t so important, not so much as that you realize it’s a war. And we’re losing, mainly because we’ve not been willing to face up to it’s full import. It’s too crazy. Too horrible. We can’t go there. We’re cowards. Look and listen to the pundits. Any of them, no matter how great you think they are. They’re giving you data points that they themselves are unwilling to connect. We’re all afraid and so we’re very easy to distract. Oh look! Gays!

Field Ballistics for Windows Phone

I just submitted my exterior ballistics app, Field Ballistics, to the Microsoft store for Windows Phone. It will be a few days until it is published. In a day or so I’ll give more details but here is some of what I submitted:

Field Ballistics is a revolutionary exterior ballistics application. Previous ballistics app are little more than glorified pieces of paper with ballistic tables. Field Ballistics uses the phones high tech capabilities to give ballistic solutions for multiple targets.

Place push pins on a map for each target automatically computing the distance from shooter to target, use the camera and accelerometer to measure the incline, use the Internet to automatically get up to date environmental conditions from the closest weather station. Select a target on the map and see the exact scope settings needed and information such as the time of flight and bullet velocity at impact.

When the shooter moves to a new location the ballistic solution for each target is automatically updated. Range and wind direction are automatically corrected using the new shooter location and information from the nearest weather station. You just enter in the new scope settings and take the shot.

Select from any of Federal or BlackHills match ammo or add your own. Input chronograph velocities and Field Ballistics corrects for the distance from the chronograph to the muzzle.

Field Ballistics is more than a glorified piece of paper. It uses the full power of your phone to give you ballistic solutions to multi-target problems.

Not recommended for calibers larger than .223 or 5.56mm.

You are supposed to use your iPhone directly as a sighting system?

Am I overlooking something here?

Sorry. I don’t think it is going to work that well for the following reasons:

  • Display brightness: With direct sunlight on the display you aren’t going to be able to see any detail, and maybe not anything at all.
  • Repeatability of the mount and even the camera stability inside the iPhone case is going to make it a 5 or 10 MOA system.
  • At short ranges, a limitation they admit, wind and ballistic calculations are so minimal that the repeatability of the mount is going to be the dominant factor. So you haven’t gained anything with the computing power you are bringing to the party.
  • Battery life: How long is your battery good for when you have the camera and CPU running?

I think it would be better if you could connect the camera through a real scope that won’t have the problems with repeatability and you get long range capability. You still have problems with bright backlighting but you have addressed two out of the three big issues.

Okay. It would be cool to have video of the target as you hit them but you can get that with something like GoPro or video glasses while using a real sighting system.

It’s a bird. No, it’s a drone!

Found on Drudge. And “this is just the beginning” they say. Of what? I ask.

For some reason I’m reminded of the “Hunter-Seekers” (or were they “Hunter-Killers”? It’s been several decades since I read the series) of Frank Herbert’s Dune. They were tiny, silent, flying assassination drones that could get into your house or pretty much anywhere else. I wonder if the IRS is looking into drone technology, but then; who isn’t?

Plastic guns are easy, try paper!

Via an email from Paul K. we have instructions on how to make a working gun out of paper. I have duplicated the instructions here for archival purposes.

I really, really, have serious concerns about using one of these. I can see where the radial strength might be adequate when using a small gauge shotshell but the recoil could still be a problem. There is no breachface and stock to prevent the shot shell from pushing the nail (firing pin) and perhaps the case-head into/through your hand.

Use at your own risk and remember that the extent of my obligation should this result in you or a friend of yours dying an unnatural death is to nominate you for a Darwin Award. If, and only if, I am in a generous mood when I learn of your date with fate.

Can’t stop the signal with crypto hashes

Following the lead of Robb and Barron I’m hosting the files to produce firearms on a 3-D printer.

One of the risks to “the signal that cannot be stopped” is that the signal could be subtly corrupted without the possessor knowing. Therefore I am computing and including the hashes of the files so that you can verify it has not been corrupted. Of course someone could corrupt the hashes posted on this blog post to match the corrupted files but I have saved copies of the hashes in a secure location for later comparison. Contact me if there is a concern the hashes have been tampered.

To compute and verify the hashes I used File Checksum Tools (free and quite functional).

The Defense Distributed file pack is here. Hashes:

  • MD5: F4784E3C4C6B6D851C3F2CFD8579B2A6
  • SHA-1: 3B733B62D8D3B08DE9BFFB94CDD308C18BF09BB0

Random thought of the day

Ry stopped by my office this afternoon and shared this bit of knowledge with me:

When you are shooting into a fire a red dot sight is totally worthless.

It’s obvious in hindsight but neither he nor I thought of it ahead of time.

Stuff I didn’t know

Double action, pre Civil War design percussion revolver. It has a fully enclosed cylinder, i.e. a top strap. What I don’t get at the moment is why there are twice as many cylinder notches as there are chambers.

This is the sort of thing I’d like to own, and yet I can give no practical reason for it whatsoever.

ETA; I think I figured out the cylinder notch thing. It must be a safety system. Colt’s, Remington and others had similar features, pins or notches in the back of the cylinder to engage the hammer, that more or less locked the cylinder half way between chambers, so the hammer could rest safely between chambers, allowing the carrier to have all chambers loaded rather than resting the hammer on an empty chamber. This revolver is simply using the existing bolt (cylinder lock) for that purpose, methinks, hence the “in between” cylinder notches.

More on communication

When I was a boy, out working the fields alone on my grandparents’ farm, I heard voices wafting in from the distance. Two men were standing next to a tractor, its engine running, and so they were shouting at each other to be heard over the engine noise. Two to three hundred yards away, I could hear nearly every word they were saying.

“Ah Hah! Unlike addition and multiplication, communication over a noise source can be asymetrical, or one way.” YOU may be able to hear ME just fine, but it may be utterly impossible for me you hear you, or vice versa. I knew that there was no possible way I could ever shout loud enough for those two men near the tractor to hear me, though I could hear them pretty well.

I’ve used this as an example on several occasions, trying to explain this as the reason why the frustrated fool on the other end of the conversation cannot get through to me. My wife, for example, has never understood this, and she will get angry when I tell her I can’t understand her as I’m washing my hands at the sink. SHE thinks I’M the dumb one, see.

Same goes for radio communication, when someone hears you booming in on a 100 watt repeater, but can’t understand why he isn’t being heard from his 3 watt handy-talkie (then he shouts into the microphone, which makes it worse, because his over modulation [FM} spreads out his three watts over more bandwidth, out toward the edges of the receive passband).

Then there are those who, when wearing ear muffs or headphones and you’re not, and you’re standing right next to them, will shout at you.

And we won’t even get in to the subject of those “low talkers” – those who will talk under their breath apparently as a means of irritating you or for some bizzare reason they want to use it as a means of feeling superior to you, because you’re struggling to hear them while they can hear you perfectly well, and so what’s wrong with you, Chump?

Cast bullets for an auto pistol

Down the rabbit hole into the esoteric. Before the current ammo shortage I decided to start casting bullets, just because I liked the idea of an extra level of independence. The 30-30 cast bullets worked OK but there’s more to do there. This time though its the 10 mm Auto.

I’ve been loading the Hornady 180 XTPs with good results, but I wanted a 200 grain cast bullet too. The RCBS 200 SWC has gotten good reviews so I got that two cavity mold a while back. The mold handles I use for the Lyman molds didn’t fit the new RCBS mold, and people were starting to run low on things. Buffalo Arms in Idaho sells a hand-fabricated-looking handle set that works like a pair of Vice-Grips. Pretty expensive and heavy, but they had them in stock. They’re great. You get VERY consistent closing pressure for each pour. I weighed 20 already lubed bullets tonight and the extreme spread was 1.5 grains, 201 gr +/- .75.

Of course, to “save money” casting bullets from one dollar per pound lead, I had to buy a lube sizer. Seating the lead bullets, I was shaving lead on the case mouths, so I bought a 10 mm M die. It expands deeper into the case than a regular expander die, plus it makes a wider spot at the mouth. I’d been seating crimping in one swipe with the jacketed bullets, but since that’s not really an option for cast, I had to readjust my otherwise permanently adjusted seating die. Now I figure I’ll buy another seat die in this “money saving” venture.

To prevent the case mouth shaving lead from the bullet upon seating, I had to put LOTS more flair on the cases. I tried chamfering the mouths a little and that didn’t help much, so now I’m working the brass a lot more, which means it will work harden sooner. The bullets aren’t getting shaved now, but the cases are so wide at the mouth that the seating die can’t be lowered nearly as much as normal or the crimp taper starts to erase that wide belling, shaving lead anyway. And that means that the seating stem is just a bit too short, so with the locking collar removed from the seating stem and the stem screwed in as far as it will go, I still have to screw the die body down to where it is narrowing the flair just a bit. That means there is no support on the case at all except at the very mouth. I noticed that if I nicely align the bullets on the case mouth by hand before seating, they now don’t get shaved. When the bullets shave, the lead that’s stuck in front of the case mouth interferes with head spacing. It’s not serious, but it is annoying.

Loading dies, at least for straight wall auto cases, are not made with cast bullets in mind. These are RCBS dies, but I doubt there’d be much difference. The whole paradigm is wrong. Since you apparently need much more flair at the mouth, and you’re shoving the case up into the die mouth-first, your die has to be too large to support any part of the case except for the very mouth, or else it will erase your mouth flair. Instead of going mouth-first into the seating die, the cases should be going head-first into a support die, and then up to a seating stem, with the bullet pre aligned before it touches the case. That way, much of the case, and all of the bullet’s drive bands, could be aligned prior to seating. It couldn’t be done “right”, in my opinion, any other way.

But we make it work, somehow, with what we have. There’s still more testing to do, but initially I got two groups of just under 5 inches at 20 yards standing unsupported. Lots more recoil than the 180 XTP loads, but my chrono got lost along a 20 mile stretch of highway in a snowstorm so no vel data. A third group was MUCH larger, so I quit. There was leading in the Lone Wolf barrel. That was before I eliminated the lead shaving at seating. We’ll see later whether the shaving verses not shaving makes any difference.

The load is 9.4 grains Blue Dot, CCI 300, OAL 1.255, #2 alloy, Super Molly lube that came with the Lyman sizer. Still don’t know if it’s a keeper, but I do know I can get off at least 10 decent shots. Whoopie, eh?

How to make a mortar

I played with some metal working equipment last weekend after not touching anything for several decades. While mostly successful I “learned a lot” without any permanent damage to the item I was working on and without leaving any of my blood or body parts behind.

Then yesterday I was looking for something else and saw this video of how professionals do things these days:

Quote of the day—Béla Nagy, et al

A combination of an exponential decrease in cost and an exponential increase in production would make Moore’s law and Wright’s law indistinguishable, as originally pointed out by Sahal. We show for the first time that these regularities are observed in data to such a degree that the performance of these two laws is nearly the same. Our results show that technological progress is forecastable, with the square root of the logarithmic error growing linearly with the forecasting horizon at a typical rate of 2.5% per year. These results have implications for theories of technological change, and assessments of candidate technologies and policies for climate change mitigation.

One; This is awesome! A variation of Moore’s Law applies to, apparently, all technology.

Two; It looks as if they had to make a tie in “climate change” to get National Science Foundation grant money. That’s really messed up. Government grants should not exist. The politics of research should succeed or fail using the money of someone other than that taken by gunpoint via taxes.—Joe]

What we KNOW…. that isn’t true

Mark Twain said: It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.” I’ve seen a lot of examples of this in my life, and heard of more. I’m sure you have too. In fact, in installment 002 of “The Stars Came Back” Helton points out that a lot of time the so-called experts have really BAD plans, and that you can’t tell what the outcome of a lot of projects will be based on the credentials of the people starting it.(He is specifically talking about climate science, in fact)

The Climate debate is no different. There is a LOT of garbage out there (and I say this a a teacher with a cert that includes “Earth Science;” I’m in the “CO2 is plant food” camp) Then, along comes something from out of the dry fields that takes on directly one of those “common knowledge, common sense” things directly, and says, “We were wrong. The solution we have been pushing for decades is CAUSING the problem!” It takes some good sized balls, and a dose of humility the size of a Hollywood celeb’s coke habit, to make an admission like that. More so to take that fact, and a much better DEMONSTRATED solution, on the road.

We all know over-grazing causes land to turn into deserts, right?

Maybe not. Maybe the solution to desertification is to put MORE beef in the fields, and on the grill. It’s a win-win-win-win, meaning the lefties will HATE it, and fight it tooth and nail. But the guy makes a good case.

More on phonetics

As often happens, I was talking to a customer over a poor cellular connection today. We have to exchange a lot of data to complete an order. He’s spelling the name of his street.

“Wait; that’s A, T, T as in alpha tango tango?” I say to confirm.
“No, it’s hotel echo papa”
“Wow!” I said “I really got that wrong” and I’m thinking to myself, “Bam! We’re home free– this guy knows standard phonetics.” Without it, we’d have had a hell of a frustrating time.

So, Young Grasshopper; learn your Standard Phonetics.

I’m still amazed and disgusted that most cop shops have their own systems, which makes it more difficult because for one, they don’t always use words that all sound completely different from one another, and too, if you know Standard Phonetics, their retarded cop phonetics don’t sound familiar and it therefore takes longer to comunicate. Moron phonetics.

Learning the standard system is easy. There are only twenty six of them, and as it happens, each one starts with a different letter of the alphabet (fancy that) so it’s really easy. It’s an international system, and most pilots, military and ham operators already know it hands down. Whaterya waitin’ for?

Practice. For example, if I look to my left on my desk, I can read off in my mind, “Hotel Papa…Delta echo sierra kilo julliette echo tango.” Stuff like that. Road signs, what have you. This should be taught in school, except for the fact that kids should know it before they get to school.

On a similar note; use text on your phone when the signal is too poor to use the more bandwidth-hogging voice communication. If you have only one bar on the s-meter it still works like a charm whereas vioce communication is two steps below impossible. I explained that to my daughter a while back, and was surprized that she hadn’t thought of it. I’d though it would have been obvious even to a teen-aged school girl– a few dew drops of bits verses a tsunami/torrent of bits, you know.

Take a guess which direction the bar will travel when the Boomerite detonates.

If you guessed slightly up and to the right you would be correct. See the red circle in the picture above.

The backstory is that Ry was trying to make a piece of art. It was mostly a failure.

Next time it will be a five gallon bucket instead of a three pound cottage cheese container. Oh, and we will be about 250 yards away so Ry won’t have to worry about it coming out of orbit on top of him.

It’s linear but does it scale?

Paraphrasing Ry as we discuss the fireball for Boomershoot 2013:

One pound explosives one gallon gasoline, no problem. 14 pounds explosives, 14 gallons gasoline no problem. The gasoline is damping the explosion and it’s not breaking any windows. It’s linear! So, 1000 pounds of explosives and 1000 gallons of gasoline should be fine. Right? What could go wrong?

As Barb L. said when Ry and I were leaving for Idaho, “I suspect that you and Ry together equal trouble, sort of like Ruth and me together equal trouble. And it is Superbowl weekend again.

Ry has a history with Superbowl weekend.

Kelvin-Helmholtz Waves

Or KH waves, or a KH instability. It’s a result of two distinct layers in a fluid traveling at different velocities. You’ll see it in rivers and streams, between bands in the atmospheres of Jupiter and Saturn, in your coffee cup, etc. In this case it’s made visible by the bottom layer being cloud, interacting with a clear layer above. The wave pattern extends from one side of the photo to the other. I had to darken the image a lot to bring out the detail. Through my polarizing glasses the waves could be seen curling in on themselves more dramatically. For really good detail in sky photos you need a polarizer, and probably a UV filter too, but my little point-and-shoot isn’t set up for such things. These KH waves are over the Clearwater River canyon above Lewiston, Idaho, seen from the south end of Moscow on my way to work the other day.

Kelvin-HelmholtzWaves

It isn’t complicated

We occasionally get someone who wants to submit an idea for a new product. They’ll want us to evaluate it in hopes that we will help manufacture and market it for them.

Here’s the deal. If it happens to be something we’re already thinking about, I most certainly do NOT want to even know what you have. You can figure out why.

Somehow there has come to be this strange attitude, or belief, that if you’re a “little guy” with scant resources, that you must tug on someone else’s coat tails and convince them to “give you a chance” otherwise you have no chance.

It doesn’t work that way, or rather it certainly doesn’t need to work that way. If you have a little gizmo you want to turn into money, start searching for companies that do machining, or injection mold building, or casting, or whatever type of manufacturing you need, contact them, get some quotes for a few hundred or a thousand units. There are small shops that do these things in practically every town larger than a mere whistle stop. Many of them will not want to talk to you about such small numbers, but some will. Keep at it. Register yourself a domain name, take some nice photos, build a simple web site and get a web host for it, place a cheap ad in Shotgun News or what have you, and BAM! You’re in business. Just like that. What’s stopping you?

It probably will not cost more than the annual or twice annual beer and cigarette expense for the average, unemployed trailer park dweller. The rest is leg-work– finding people who can provide the specific services you need, and so I think that if you’re not willing to give yourself a chance, why should someone else give you that chance? Hmm? You won’t go out on a limb for your idea, but you want me to go out on a limb for your idea?
