TechTV's Catalog of Tomorrow

I have TechTV playing in the background while I'm working here, and just now saw an intruiguing ad for a book, TechTV's Catalog of Tomorrow. The images flashing by included some Foresight Institute graphics illustrating nanotechnological cell repair machines, apparently contributed by my friend Chris Peterson. The other thing that caught my eye was a dewar with an Alcor Life Extension Foundation logo: I'm a neurosuspension member of that cryonics organization myself.

This is another book I've not yet read, but find sufficiently interesting to point out to my readers. I'll review it when I lay my hands on a copy. In the meantime, the Amazon entry I point to here has 52 sample pages for perusal - lots of eye candy - with the index pages listed in full.

Leica 8+12x42 Duovid hunting binoculars

A friend of mine just today ordered a pair of Leica 8+12x42 Duovid hunting binoculars. Per the advertising blurb on the Leica website (English version, of course):

Leica heralds a new era in binoculars: The LEICA DUOVID 8 + 12 x 42 is the first highend binocular worldwide that features switchable magnification. That makes it an outstanding choice for use in hunting, because it provides brilliant images, both at great distances as well as in critical poor light situations.

In wide-open hunting grounds, observation must often be conducted over great distances. The12-power magnification is ideal for this purpose. The 8-power magnification, on the other hand, allows an excellent overview over the entire range - with an absolutely stable image, a large field of view and great depth of field. Outstanding ergonomics make vibration-free viewing possible even at high magnifications.

My friend has not received his binocs, so we don't yet have a review. These are pricey glasses, but I'm sure worth the cost. If anyone has had experience with these glasses, feel free to comment here. I've been a Steiner guy myself for the last couple of years, but can be convinced to switch.

Toxophilus or the Schole or Partitions of Shooting, by Roger Ascham

I'd mentioned earlier that I'd seen "Conquest: Bow & Arrow" on the History Channel last night, but didn't mention that Peter Woodward had cited a work I've not yet read, "Toxophilus or the Schole or Partitions of Shooting", published original in 1545 by Roger Ascham, which Woodward described as the first European book on the practice of archery.

There are some interesting excerpts from Ascham's book quoted in the web-based survey of the art "Construction of the Medieval Arrow", e.g.:

The deep and long nock is good in war, for sure keeping in the string. It must be narrow enough to hold the string, not grip it too much, strong enough for the sudden blow of the string not to break the shaft, and smooth enough for it not to cut the string.

and:

In Crete and Italy they used to have their shafts of reed... But, because such shafts be neither easy for Englishmen to get, and, if they were gotten, scarce profitable for them to use, I will let them pass, and speak of shafts which Englishmen, at this day, most commonly approve and allow. . {which} may be of such diverse woods as: Brazil, Service-tree, Turkey wood, Alder, Fustic, Blackthorn, Sugar-chest, Beech, Hardbeam, Elder, Birch, Asp, Ash, Sallow, or Oak.

I've not yet acquired a copy for myself - anyone have one I can buy, or, better, have one to donate for review here? - but will eventually lay my hands on one.

Interestingly, Webster's dictionary of 1913 has "Ascham" listed as a noun.

Conquest: Bow & Arrow on History Channel, repeated 13 & 14 January 2003

I saw this last night on the History Channel, narrated by "Actor and fight master Peter Woodward":

One of man's earliest effective hunting weapons, we learn why the bow and arrow became so dominant in history. Our combat team is sent to the woods to make their own as we study the craft of the bowyer and fletcher. We learn about Egyptian bows and try to fire accurately from an Egyptian chariot, and experiment with North American Indian bows--composite bows of horn and wood. And reenactors, using rubber-tipped arrows, recreate what it was actually like to be subjected to a "cloud of arrows". TV PG

It was quite an entertaining show, with some interesting tidbits such as the ability of the English longbowman to deliver 2 arrows simultaneously... by delivering one in a parabolic arc on target - like a mortar round - and quickly following through with a directly aimed second shot with a correspondingly short time on target. Amazing stuff.

I hadn't appreciated how underappreciated the bowman was on the European medieval battlefield, akin to the despised Japanese rifleman I've mentioned in another post here. A well trained, strong bowman with good equipment - the best of the English longbowmen, for example - was a relative rarity on the European battlefield. Vastly more common was the ill-trained, unmotivated, barely fed, despised-by-the-regulars draftee bowman, who was given little or no support from infantry or mounted armor.

When knights were captured, they were often ransomed. When archers were captured, they were usually killed.

One lesson from the show: if you're an archer, use your only advantages - quick mobility and ability to project force - by drawing your encumbered enemy into (to him) disadvantageous terrain, which means get the armored knight into the woods... where you can pick him off from behind trees - for that matter, from high up in trees - and separate him from his mates.

The program will be repeated 13 & 14 January 2003.

Gary Moro sojutsu (spear) seminar 15 February 2003, Bay Area Buyu Center

Patrick McKee passes along a notice that Gary Moro, teacher of Yachigusu Ryu aikijiujutsu martial arts in San Francisco, will be teaching a sojutsu (spear) seminar at the Bay Area Buyu Center on the 15th of February 2003.

Gary's a good guy I've met a few times at Don Angier seminars in the Bay area, and while I'm a student of a different art (Bujinkan Budo Taijutsu), I will certainly try to attend his seminar. The arts of the Sengoku Jidai (the Japanese Warring States period) were all about combat; study them from the good teachers, where and if you can find them.

Carrying a concealed weapon allows one, regardless of gender, age, or physical ability, to control his own immediate environment and thereby have options in various emergencies that unarmed persons do not enjoy. Carrying a gun is simply part of recognizing and accepting responsibility – responsibility for one’s own actions, one’s own safety, and the security of one’s own family. Indeed, with the level of lawlessness evident in today’s society, it may be the social duty of decent, intelligent people to arm themselves.

Penn & Teller: Bullshit!

4 weeks from now on the Showtime network will see the debut of libertarian comedy duo Penn & Teller's "Bullshit!":

On January 24 at 11:00 PM ET/PT SHOWTIME will present the controversial new series PENN & TELLER: BULLSHIT! Master showmen Penn & Teller promise an aggressive, irreverent exposé of taboo topics using the duo's trademark humor, knowledge of carnival tricks and con-artistry, as well as hidden cameras and blatant confrontation. Each of the 13 half-hour episodes includes interviews and undercover segments intertwined with elements of Penn & Teller's non-traditional comedy routines.

I'm really looking forward to this.

Quote of the day

As opportunities to learn about firearms dwindle, so do opportunities to learn the virtues inherent in responsible gun ownership. Far from protecting them from danger, keeping our children from learning about guns leaves them defenseless in situations where that knowledge could be life saving. The best lesson we can teach our children about guns is that they are powerful tools that can be used for good or bad. In defense against lethal aggression a gun is a piece of safety rescue equipment.

Nevada Pistol Academy moving to Front Sight main campus

Earlier this afternoon, I received a call from an acquaintance in Las Vegas, who told me that Nevada Pistol Academy was closing shop at the end of this month (31 December 2002). I was a bit shocked, because for me this would mean no more "guns at cost", which has been a great attraction of the shop at the south end of the sea of lights.

I called the shop a few minutes ago and spoke to manager Todd Anderson, a really nice guy I've met before, and he explained that I had half the story: yes, NPA is vacating its present rented facility at the end of the month, but no, they're not going out of business. They're simply moving shop to the Front Sight main facility in Nye County, about 40 miles north, and taking over the FS Pro Shop operations, which will mean a marked improvement in overall selection, opening hours (normal hours rather than only when classes are in session), and a competitive place to buy guns.

Importantly, too, they'll be transferring their FFL to the new facility, which means they'll not be surrendering their Form 4473 files to F Troop.

Lassen Community College Gunsmithing program

I'd meant to mention this after my attendance at the last Big Reno Gun Show. A friend of mine on a mailing list I run, exi-liberty, mentioned that he's considering studying the art of the gunsmith; at that gunshow, I picked up a catalog for Lassen Community College, home of the famed NRA-affiliated Gunsmithing program:

We are the only Two Year Degree program fully accredited west of the Rocky Mountains. Lassen Community College is fully approved for VA and Rehabilitation students. We offer a two year A.S. Degree program as well as many different certificates with the additional opportunity for students to take a third year post graduate program to receive a Journeyman Gunsmith certificate.

The program is located on the college's campus in Susanville, California, about an hour's drive from Reno, Nevada. It's worth noting for Nevada residents that the college has a "good neighbor" tuition program specifically to attract them across the border to campus.

The college's gunsmithing program is unmatched in quality and scope, and features courses specifically tailored for the working professional: you can take each course in one week, starting Monday and finishing Friday. Neat deal.

The time is now near at hand which must probably determine whether Americans are to be freemen or slaves; whether they are to have any property they can call their own; whether their houses, and farms, are to be pillaged and destroyed, and they consigned to a State of Wretchedness from which no human efforts will probably deliver them.

Let us therefore animate and encourage each other, and show the whole world that a free man, contending for liberty on his own ground, is superior to any slavish mercenary on earth.

Whiteouts in Reno: everything in the air

Just saw on Fox News that the weather is still going nuts. I experienced literal hurricane-force winds on Highway 95 just south of there on Saturday, and feared the sands would strip the paint off my car. I was whacked by tumbleweeds like never before. Later that night, massive snowstorm in Carson City, flakes the size of Pringles chips.

I'd planned on snowboarding Mt. Rose yesterday, but skipped it for some work. Fox mentioned that a skier was lost off-trail, and I see they're closed for the day!

I feel somewhat vindicated in my "paranoia": even in good (initial) weather, and even in cities, I always carry food, water, winter gear, and chains.

Another interesting site: Accurate Reloading

Accurate Reloading looks like a bunch of guys that love guns (located in some middle eastern country), big game hunting, wildcat cartridges and amateur gunsmithing.

There are some hilarious videos of people shooting various cartridges like the 577 Tyranasaur, 600 and 700 Nitro Express in very light rifles. How does 14,000 ft/lb of energy strike you? You know you have a big cartridge when you have to "build" it on a 50 BMG action! Now add a 12-13 pound total rifle weight and no muzzle break!

The site also has an amazing amount of great data on reloading and ballistics on

Quote of the day

The general rule is that an unconstitutional statute, though having the form and name of law, is in reality no law, but is wholly void, and ineffective for any purpose; since unconstitutionality dates from the time of its enactment, and not merely from the date of the decision so branding it. An unconstitutional law, in legal contemplation, is as inoperative as if it had never been passed. Such a statute leaves the question that it purports to settle just as it would be had the statute not been enacted.
Since an unconstitutional law is void, the general principles follow that it imposes no duties, confers no rights, creates no office, bestows no power or authority on anyone, affords no protection, and justifies no acts performed under it ....
A void act cannot be legally consistent with a valid one. An unconstitutional law cannot operate to supersede any existing valid law. Indeed, insofar as a statute runs counter to the fundamental law of the land, it is superseded thereby.
No one is bound to obey an unconstitutional law and no courts are bound to enforce it.

Sheer barbarism! Wine shipment limited in some states!

My first time shopping Wine.com, I'm asked with each selection if the U.S. state I previously indicated is indeed the state to which I'll be having the wine shipped. I finally went to the "Why is this important?" help link and read this:

Although we can ship wine to more than 80% of the U.S. population over age 21, a few states do not allow their residents to receive wine shipments. If you are choosing a gift for one of these states, your product choices will automatically be limited to our line of tasteful and practical wine accessories.

Brian Wilson, who broadcasts from the District of Columbia - one of the affected statelets - for the San Francisco libertarian/convervative KSFO AM 560 market, and who also loves wine, has I'm sure had choice words about this insanity.

Inova X5 Mini Spotlight: found the one I lost!

I thought I'd lost the one I carry in my back pocket, but I found my Inova X5 Mini Spotlight under my car's driver seat... I really do need to look down there routinely.

I love this thing! It uses the same lithium ion batteries I use in my Surefire 6P and M3 tactical lights, but those batteries last 10 times as long in this unit. This means I can (and do) reserve my 6P solely for its intended use, and the Inova as a utility light. I just now measured mine at 2cm wide by a shade under 12cm long. Drop it in your pocket and forget about it.

And like the ASP Key Defender I reviewed a few weeks ago, it's made of durable machined aircraft aluminum. A bit shorter and thicker than the ASP, the Inova could make a fine little handheld impact weapon.

I will not attempt to discover whether legislation is 'needed' before I have first determined whether it is constitutionally permissible. And if I should be attacked for neglecting my constituents' 'interests,' I shall reply that I was informed that their main interest is liberty, and in that cause I am doing the very best I can.

The picture from the Bugei tameshigiri seminar

I'd mentioned a few days ago that someone on a dojo mailing list alerted us to the fact that I'm in a picture on page 2 of the new Bugei catalog. Here it is; I'm in the middle. James Williams to my far right; Big Tony is to my right.

You can't see it very well, but I'm holding James' personal Samurai Koshirae Katana, which he mentions in the latest paper catalog has over 4,000 cuts... last year's catalog says 3,000. I came to the tameshigiri seminar with a cheap sword, so he generously offered the use of his own, which was superb. I now own one of those, as well its matching tanto. Eventually, I'll save for the matching shoto.

The Thermopylae Group & The Self Defense Initiative in California

At the Big Reno Gun Show last weekend, I picked up a paper brochure entitled "A Proposal for Amending the California Constitution", from The Thermopylae Group in San Jose, California. The text of the Self-defense Initiative is composed of these 3 short paragraphs:

The Proposition

The inalienable right to defend life and liberty as set forth in Article I, Section 1 of the California Constitution includes the fundamental right of each person to keep and bear arms for the defense of self, family and home. This right shall not be infringed.

1. All State government action regulating the right of law-abiding persons to acquire and possess arms for the defense of self, family and home, shall be subject to strict scrutiny, in the same respect as the freedoms of speech and of the press. All county, city and local government action on this subject is preempted by state law and this Amendment.

2. This Amendment does not limit the State from regulating the acquisition and possession of arms by: felons, minors, the mentally incompetent, and any person subject to restraining orders based upon their own violent conduct.

The group plans to place the initiative on the ballot in 2004.

Penetration and blocking of radio waves

Radio waves are attenuated by almost all objects they pass through, e.g. air, people, trees, buildings and the ground. Dense objects such as earth or metals block radio waves very well. Only a few feet of either can make radio communications impossible. However, radio waves also bounce off objects, and this effect can be used to allow communications around corners and inside otherwise impenetrable objects such as steel buildings. Higher frequencies tend to bounce and penetrate more, thus UHF radios are the most suited for work inside buildings and cities. There is a practical limit to this however, and beyond 400-500 MHz the penetration of radio waves starts to fall off again.

Sensitivity

Good receiver sensitivity is an excellent way to make up for low transmit power. Increasing transmitter power takes more energy, and thus translates into shorter battery life on portable radios. Increasing receiver sensitivity usually does not require more power, so this is a desirable characteristic. Most modern radios have excellent sensitivity. Sensitivity is usually measured in microvolts, also abbreviated as uV. The lower the number, the better the sensitivity. A good radio will have a sensitivity of 0.2uV or lower. Up to 0.4uV is acceptable for UHF radios.

Polarization

Radio waves have an orientation, usually vertical or horizontal. Note how external TV antennas have all their elements lined up in a flat fashion (horizontal polarization), while CB and two-way radio antennas point straight up (vertical polarization). Having the polarization different between antennas can cause significant signal loss, thus it is important to always mount antennas in the same direction (vertical for most two-way radio applications).

Antenna height

At higher frequencies (30MHz and above), the height an antenna is above the ground has a direct affect on how well it performs. High frequency radio waves are blocked by the ground and tend to travel about the same as one’s line of sight. This is the usually the main limitation on the distance one can communicate. The higher one is, the farther they can see, and the exact same principle applies to radio waves. A 1-watt portable may only work for 2-3 miles at ground level. If you put that radio on a 5,000-foot mountaintop, the range can be increased to 10-20 miles or further. A good rule of thumb is if your radio contact drops off, try moving to higher ground.

Gun Shows now banned in San Mateo County, California

Less than 48 hours ago, San Mateo County, California supervisors unanimously voted to ban gun shows on county property. This means the TS Gun Shows run at the Expo Center in Redwood City are history, unless the NRA successfully appeals in the 9th Circuit Court ("the most overturned court in the land").

Expect San Mateo County revenues - the ones they'll now lose on the rental of the Expo Center - to be made up by increased taxes on, oh, say, ammunition in the county's gun shops.

It was the first time I'd shot there, and was very happy with the facilities, the well-stocked shop, and the excellent, knowledgeable people there.

Tactical Radio Communications, installment 5

[PREVIOUS INSTALLMENT]

Gain

In radio terms, gain means multiplication. Gain is used with respect to amplifiers and antennas. Amplifiers obviously have signal gain, as that is their purpose. Antennas can also have gain. They accomplish this by focusing the energy supplied to them into a beam. Antenna gain works in both directions, transmit and receive. Gain is specified in dB units. dB units are a logarithmic measure, which means that the gain increases at an ever-faster rate for a constant change in numbers. Some simple rules to follow if you don’t understand what logarithmic means are as follows:

0dB = 0% change
1dB = 10% change
3dB = 70% change
6dB = 200% (or 2 times)
10dB = 300% (or 3 times)
20dB = 1000% (or 10 times)
40dB = 10,000% (or 100 times)

An antenna with 6dB gain will transmit 2 times the energy as a no-gain antenna. Thus a 5-watt radio connected to a 6-dB gain antenna will transmit a signal with the effective strength of 10 watts. Since antenna gain works in both directions, any received signals will also appear to be twice as strong.
