AmericanMercenary, a U.S. army solider, gives us data on the effectiveness of .50 caliber rifle fire on aircraft.
That should put the myth propagated by the VPC and Brady Campaign to rest. At least for rational people.

If you want to save yourself some time by not read my late night rambling just read three sentences from Say Uncle on this topic.
As an engineer I make a lot of trade-offs. Execution speed and size (assembly language) versus code clarity and development time (high level languages) used to be a big trade-off. Calculating results every time you need them or caching them in RAM is a trade-off (it didn’t use to be that way but today the answer is usually you want to calculate them every time). Do you load everything in RAM for quick access or leave it on disk until you need it? Do you bringing a new hire up to speed or do you do it yourself?
I can whip out some code that will test a hypothesis in a few minutes or an hour and not worry if there is a single comment in it or if it handles a single error condition. To implement that same functionality in a product that literally millions of people will use, sometimes millions of times a day (or even per minute) may take weeks of effort by a team of people. It will involve specifications, design documents, a test plan, manual testing, automated tests, unit tests, code reviews by multiple peers, and alpha/beta testing by thousands or even 10s of thousands of end users. It only takes me a fraction of a second to decide how to proceed when I know the final goal for the task at hand.
Man minutes versus man months of time involved. Two different extremes in the effort involved in implementing, essentially, the same functionality. The difference is in what I was attempting to accomplish.
I’ve been making engineering trade-offs for over 30 years and most of the time it comes pretty easy to me. When my officemate, a very smart person but a fairly new entry into actually producing deliverable code, asks for advice on a trade-off it takes more time for her to ask the question than for me to arrive at the correct answer.
Another example comes from this morning. My boss came into my office and asked, essentially, “Do we ever return an answer of less than ‘X’ for condition ‘B’?” I knew my code didn’t do that directly but there were times when my code got the answer from the server rather than computing it directly and I couldn’t say for certain without checking with the server people. I started to go down that path and explain how the server might come up with a different answer and I barely got started into the fine details when he stopped me. “Let me give you some more context”, he said. The context was he was writing an email with the target audience of upper management who would not care about the fine details. When he asked the question I thought there was some bug that had been reported and he wanted to know if it really was a bug and if so who it should be assigned to. Without knowing what he was trying to accomplish I had made the wrong trade-off. I was giving him more and more detail when he really needed validation of his high level overview.
As a gun lobbying organization the NRA-ILA makes trade-offs too. What they are trying to accomplish is to improve, and in certain worst case scenarios minimize harm to, our specific enumerated right to keep and bear arms. Nearly all other considerations must be given a lower priority.
At the NRA Annual Meetings last month I spent a couple hours talking to a NRA board member. He explained why they had done certain things in the D.C. lawsuit (for the most part I am not at liberty to discuss them) and had avoided the U.S. Supreme Court for decades. The next night (or was it the night after?) I spend time with Alan Gura who had a different view of the NRA contribution to the D.C. lawsuit. It was Gura’s contention that NRA-ILA really knows their stuff in regards to legislation but the same people attempting to handle court battles results in people working out of their area of expertise with less than optimal outcomes. My simple take on the topic was that the NRA was trying to avoid a disastrous loss and Gura was trying to get solid win. They both have our best interests at heart but in certain situations ended up “fighting over the ball” and risked fumbling it for a loss.
I think the people that are upset with the NRA support of Harry Reid don’t really understand the trade-offs involved and what the NRA is trying to accomplish. To best support the members, the gun owning people of this country, they have to play a “chess game” where they can never take back a move, the pieces are clouding in smoke, the playing field is shifting, the rules are only partially known and subject to violation by the individual pieces at any time. Try thinking three or four moves ahead under those conditions and see how well you can do. The NRA plays that game very well. They are experts at it. Sometimes when an expert is at work you will be baffled at the moves they make.
To the simple minded observer if you put a “good conservative” in office you will automatically get support for gun rights, hence you should always give support to “good conservatives”. Even an amateur like me can see far enough ahead to see a problem with that in certain situations. There are trade-offs involved. With a ‘D’ beside his name and lots of seniority Reid has lots of power that someone with an ‘R’ and little (or no) seniority would not have. That is just one trade-off. Another is that in certain jurisdictions a “good conservative” is not electable. The demographics of that district are such that the NRA can curry favor with someone that will be in a position to help us or they can try to defeat them during the election then try to make up with them after the election. Another trade-off is that some people like everything, or most everything, the Democrats offer but support our right to keep and bear arms. To a certain extent I am baffled by both the Republican’s and the Democrats. I really don’t understand (and don’t think they do either) the philosophy behind their politics. My guiding political principles are pro freedom. Each party has something to offer and a lot they want to take away from me in this regard. There are trade-offs in who I vote for.
In the case of Harry Reid an NRA lobbyist said this about him in an email discussion:
I have candidates for office running against pro-gun Dems who expect that NRA is going to endorse them as the pro-gun Republican challenger over the pro-gun Democrat incumbent…and tout all of their other “conservative” positions as proof that they’re the better candidate. They get frustrated with me, but I have to remind them that NRA doesn’t use whether you are pro-Life and small taxes to determine your endorsement or grade — and a large number of our members appreciate that, because they don’t agree with conservatives or Republicans on anything but guns! 😉
Whether they like it or not, Harry Reid has voted with gun owners and NRA 100% and used his position in the Senate to advance gun ownership rights in recent years. The Obama Admin was forced to sign a bill with Guns in Parks because Harry Reid allowed the Amendment. The House is holding up DC voting rights because Harry Reid allowed the DC gun rights amendment to the bill.
If Harry Reid isn’t the Senate Majority Leader, we’d have Chuck Schumer or Dick Durbin — think we’re going to get any of those amendments on bills with THEM in charge? No — it’ll be more Lautenberg crap.
In the eyes of an expert political lobbyist the making of the decision about Reid took less time than it took to write the first sentence of the explanation and it’s clear that is the correct answer for gun owners. Those that try to change the NRA support of Reid risk fumbling the ball to the loss of all of us.
As I mentioned before I broke my new video glasses while taking them off. I considered just gluing them but decided to call and see if I could purchase a replacement part. I called the number in the user manual for Global One Sales & Distribution (814-669-1953) and was told they would ship me the new part but recommended I send them in for repair. The camera is in that part of the frame and there are wires going back to the processor and memory card. The cost, including shipping back to me is $40. I sent them in for repair.
He asked me how I broke them. I told him and he said I was for the fourth person to break them taking the glasses off while the lanyard was attached. They haven’t had other people break them at all. I advise not using the lanyard. What happened to me was that I tried to take them off with one hand holding on to the frame just in front of my left ear. As I pulled them over my head the lanyard caught on my right ear and the glasses were pulled as if it were a wishbone. The lanyard had a large moment arm (engineer speak for “big lever”) and the frame could not handle the force.
There are a few other things of note here. 1) I could not find a website for “Global One Sales & Distribution”; 2) The phone number 814-669-1953 (a Texas area code) is associated with a Self-Storage facility in Pennsylvania which has the same address as that which I was requested to ship the glasses to; 3) These glasses have more features (via a comment from wizardpc) and cost less than $75 (I paid $239 + tax for mine from Afton Arms who had a booth at the NRA meeting).
I walked over to son James place for dinner and videos after work tonight. I decided to wear my new glasses and open carry. The video was boring so I didn’t both to post it.
On the way back it was cool and I put my coat on and it covered my gun. Besides they had the polarized lenses installed which would have made it difficult to see at night. In the entrance/exit to his condo complex there were two cop cars and another car. I turned on the video and just held them as I walked past.
The video was as good as could be expected in the low light. Here is a screen capture of one of the frames:

My expectation is that if there is enough light you can see then the video will be usable.
Unfortunately they broke when I took them off (they were hanging from a lanyard around my neck) when I got back to my place. The frame just above the right eye broke. I think I can glue them and then if I am very careful with them they will still be usable.
I participated in a Steel Challenge match today. I used my new video glasses (I have Sportsman Eyewear model 465 ) and then edited out most of the boring stuff. Here is the result:
I learned some things. When obtaining video I should move my head less. When asked, “Are you ready?” I should keep my head still instead of nodding.
The electronics must have some automatic gain control on the audio. The first string of fire you can hear the R.O. and first shot well. Then it gets much quieter and you can barely hear the R.O. and the shots are muffled some.
The frame rate is supposed to be about 35 fps. This is really too slow to capture what I see when shooting. In the video it seems to go much faster than when I am actually shooting. I see far more than what you can see in the video.
Still, I like what I see and plan to do this again taking into account the lessons learned.
Fellow shooters had other applications for the glasses too. The first one I heard today, “This will revolutionize the home porn industry.” Yeah, I had thought of that too. Don’t expect to see any of that on this blog.
Another suggestion was to get about $5000 in cash and go through TSA while wearing the glasses to capture them hassling you. “What would that accomplish?”, I asked. “Maybe you could get someone fired.” “But I want them ALL fired.”, I replied.
Just anytime you are interacting with authority they could be a great asset.
And in specific, from John Hardin, in the comment here came what I thought was the best suggestion. Use them when open carrying. Great idea!
While at the NRA annual meeting I bought a pair of glasses with lenses for sunglasses or safety glasses. The also have a camera (still or video with microphone) built in. The main reason for getting them is for shooting. I expect to be able to get feedback for training (pistol matches) and for shooting explosives.
The results are suprisingly good. Here is the view from my driveway (scaled down from 1080 x 1024 to 600 x 480)–The View From North Central Idaho:

Tomorrow I have a Steel Challenge match I am going to. I’m really looking forward to the video.

The U.S. Army is working on getting some new ordinance:
The Army is fast tracking a GPS guided 120mm mortar round to Afghanistan in response to an urgent request for precision mortar fire from commanders on the ground there, and should be fielded by the end of the year. Called the Accelerated Precision Mortar Initiative (APMI), it improves upon the current round’s 136-meter Circular Error Probable (CEP) reducing it to about 10-meters.
Reading the comments to this article you will find out that 10 meters is the maximum. They are hoping to get about 5 meters.
Just a few minutes before reading this I had pointed out to Barb how accurate the location information given by my Windows Phone 7 Series is. Not only did it put the little diamond for the location of the phone on the correct house–it put it in the correct corner of our house.

I got about ten percent on this little test.
This is consistent with technical papers that I have read on the effectiveness of picture ID. The human brain is an amazing thing.
I just got back from work after 17 hours.
Crystal is finishing up a new test and things were dying in inconsistent and strange ways in the middle of the test. It looked like it might be my problem.
I certainly held a good share of the responsibility. There were a couple of big memory leaks which I was responsible for. I fixed those and the test now sometimes runs to completion. Hiep will be surprised in the morning to find several new bugs on his plate. He had more, but smaller, memory leaks than I did.
It’s a good thing we are investing so much in automated tests. These bugs only showed up with a cross country trip. Crystal started us out in Redmond and we died somewhere in the Great Plains a few minutes later. We now sometimes make it to New York City.
I did get some laughter relief during the middle of the day. We were trying to recreate the problem and she asked me, “Do you ever use Depends?”
Ahh…. No.
From the context I knew she was talking about a software tool that probably checked for dependencies but I didn’t know of the tool she was referring to and decided to tease her about the inadvertent insult she just made. I frowned at her and told her, “I’m not that old!”
We both started laughing and my officemate then wanted to know what she had missed. Being an India native Depend had to be explained to her. More laughter then ensued.

Windows Phone 7 Interface: Microsoft Has Out-Appled Apple
[And to make sure those coffin nails for Apple stay tight I’ve been at work for nearly 15 hours straight now.
I’m running tests after fixing bugs that would only show up as somewhat excessive battery drain if multiple failures in the entire system (including network connectivity and/or servers temporarily being missing some data) occurred.–Joe]

Update: Yeah, yeah. I was in a meeting and didn’t want to spend the time looking for the proper name. I got the words correct. Just not in the right order.
As a software developer deeply involved in providing location information to applications running on cell phones I have some advice if this concerns you:
Amid all the furor over the Bush administration’s warrantless wiretapping program a few years ago, a mini-revolt was brewing over another type of federal snooping that was getting no public attention at all. Federal prosecutors were seeking what seemed to be unusually sensitive records: internal data from telecommunications companies that showed the locations of their customers’ cell phones—sometimes in real time, sometimes after the fact.
…
Prosecutors “were using the cell phone as a surreptitious tracking device,” said Stephen W. Smith, a federal magistrate in Houston. “And I started asking the U.S. Attorney’s Office, ‘What is the legal authority for this? What is the legal standard for getting this information?’ “
Those questions are now at the core of a constitutional clash between President Obama’s Justice Department and civil libertarians alarmed by what they see as the government’s relentless intrusion into the private lives of citizens. There are numerous other fronts in the privacy wars—about the content of e-mails, for instance, and access to bank records and credit-card transactions. The Feds now can quietly get all that information. But cell-phone tracking is among the more unsettling forms of government surveillance, conjuring up Orwellian images of Big Brother secretly following your movements through the small device in your pocket.
…
The tracking is possible because either the phones have tiny GPS units inside or each phone call is routed through towers that can be used to pinpoint a phone’s location to areas as small as a city block. This capability to trace ever more precise cell-phone locations has been spurred by a Federal Communications Commission rule designed to help police and other emergency officers during 911 calls. But the FBI and other law-enforcement outfits have been obtaining more and more records of cell-phone locations—without notifying the targets or getting judicial warrants establishing “probable cause,” according to law-enforcement officials, court records, and telecommunication executives. (The Justice Department draws a distinction between cell-tower data and GPS information, according to a spokeswoman, and will often get warrants for the latter.)
…
Al Gidari, a telecommunications lawyer who represents several wireless providers, tells NEWSWEEK that the companies are now getting “thousands of these requests per month,” and the amount has grown “exponentially” over the past few years.
Of course this is a two edged sword. If they can use your cell phone as evidence you were at a given location then you can use it to show you were not at some location. Leave your phone at work/home or in a friends car if you need to take supplies to your Jewish friends in the attic.
My advice is that no matter how careful you are with the applications you install or “disabling” the GPS or location services that isn’t good enough. The cell phone company will still know where your phone is within a few hundred yards anytime it is turned on. And with some phones it’s possible for you to think it is turned off when it actually is still functional at a level sufficient for your cell phone service provider to get location information.
As a friend of mine in the cell phone manufacturing business once told me, “I don’t know exactly what’s in the phone software. But I do know the phone only has one battery.”
This and this is very good to see.
Not only from the standpoint of being proud to have contributed to the project but this sort of press might positively affect my bonus and salary.

That’s fire and brimstone. This is pure gun geekery, and even for gun geeks its nerdy because it’s about percussion guns of the 1800s. You’ve been warned.
Saturday, Nephew and I tried some heavy loads for the repro 1858 Remington revolver. I’d been using a 28 grain powder charge and a round ball with decent results, but wanted to try something with more pep. Civil War era military loads ranged from very light, to as much powder and lead as could be stuffed in the cylinder. To start, we tried round ball (~140 grains) over a charge of 39 grains of 3F Goex with a greased felt wad in between. That load filled the chambers completely and delivered an average of 925 fps at 10 feet with an extreme spread of 46. Not too bad. The 29 grain charge was yielding a velocity of about 850 fps.
It’s like pulling teeth to find acceptable “conical” bullets (“bullet shaped” as opposed to a round ball) for these “.44” percussion revolvers unless you cast your own, which I don’t. I did find some Buffalo Bullets 180 grain jobs that fit the chambers nicely, and ordered 100 of them to try. Since the bullet takes up more room in the chamber, the most powder I could get in and still seat the bullet below the cylinder face was 30 grains. But, wow. Average velocity was 1047 fps. That’s a tad better than a .40 S&W, and matches the V of a .45 Auto load in the Speer manual for their 185 gr GDHP. Extreme spread was 67, with a standard deviation of 21.
That was with two different people doing the loading. I’m going to guess that with the same person loading all the rounds, the charge weight and ramming pressure would be a little more consistent, and so too the velocity. Groups with this load opened up slightly from last week’s all-ball venture, but not enough to be sure. This time was in direct sunlight, which makes aiming a little more difficult.
The extra pressure it takes to move the heavier bullet, which also has more friction surface against the bore, I will assume ramps up the powder’s burn rate. More velocity with less powder and a heavier bullet. Neat. We’ve found a performance, or efficiency, zone. More pressure equals more heat, equals a faster, more complete burn inside the bore, equals yet more pressure.
This is how guns (and sometimes chemical factories, engines, etc.) blow up– things look great as you increase the pressure and temp a little. The reaction speeds up, a little bit more, things are doing fine, a little bit more and, Boom!. A threshold is reached and a runaway reaction takes place. You shear some bolt lugs, or burst a cylinder, etc. and maybe you go home with slightly fewer or slightly misshapen body parts. That can be embarrassing.
I wasn’t worried about this load in a modern repro made with modern steel. When these revolvers were designed and built originally, metallurgy wasn’t anything like it is today, and even back then they were known to stuff the chambers full on a regular basis. Further, it makes no sense to build a cylinder that will take more powder than it can handle with the commonly used “44-100” bullets of up to 250 grains. That would take more material and make the gun bigger and heavier, for no other reason than to encourage over-pressure loads. I’m also running on some faith that they wouldn’t have done that (though the much longer 1847 .44 Colt “Walker” cylinder was known to occasionally let go). Remember that back then there was only black powder, not the wide spectrum of nitro powders we have now. All they had to control the powder’s burn rate were different granulations of the same mixture (though brand and lot inconsistency would likely have thrown in some degree of uncertainty). With smokeless propellants you can get into a LOT MORE TROUBLE making your own loads.
Here’s Nephew torching off one of the heavy loads. The bullet has been on its way for about a millisecond, as the gun is still in firing position and the hot gas (I mean hot– this is in direct sunlight) has traveled a foot or so out from the muzzle;

Below is the same shot in full recoil a fraction of a second later. Forget about quick follow-up shots. You can’t see the target until the smoke clears. By then you’re re-cocked and ready to go. A side wind would be a big help in this case;

Today’s rapid fire guns wouldn’t be worth as much if they had to run on black powder. For one thing you wouldn’t be able to see squat. It is “interesting” to take a shot, and find that your target has simply disappeared after the smoke has cleared. There’s that moment of uncertainty.
I like the slow, frame-by-frame animations as below. You can see the mechanics of the recoil (though a high speed camera would be nice). You can watch the force wave travel from his wrist, into the arm, the shoulder, and whole torso. Nephew’s grip is fairly relaxed, which isn’t a problem with a medium weight 44 revolver. Some people hate animated gifs on a web page. I’m one of them, but this is for science;

You shouldn’t haul off and max out your charcoal burner just because I did. I’m not saying it’s the thing to do. What I can say is; I still, for the moment, have all my body parts (and gun parts) and all are operating satisfactorily, thank you. I have a load that’s within the range of those used in the 1860s for the Remington New Model Army revolver and 1860 Colt Army, and it matches some of the .45 ACP loads for a ~180 grain bullet.
Now here’s a puzzler. I’ve had barrel leading in modern revolvers and autos firing bare lead, hard-cast or swaged bullets. Using pure, soft lead bullets in the ’58 Remington and ’51 Colts, no leading has been observed, even with these loads that achieve modern handgun KE levels. I don’t know why. Is it the grease? But we’re told in no uncertain terms never to lubricate a modern gun bore, while black powder guns are greased all to hell. Is it the propellant temp? But the KE is the same.
Deep down in the O/S you will find a location application programming interface. Below that you will find code that converts the existence of Wi-Fi and cell tower radio signals into a latitude and longitude. That (and a few other things) has been my job for the last several months.
This is just one small piece of a very large and impressive picture.
As Sean just said a minute ago in an IM, “Wow. You showed me some neat stuff Friday, but I was still impressed by today’s reveal. With this piece of the puzzle, I get a tingling feeling up and down my leg. Like we really might be entering a new golden age for Microsoft.”
