			<content:encoded><![CDATA[<p>While writing up the post on <a href="http://standardmischief.com/blog/2011/04/16/great-recession-skillz-improvised-shotgun-slugs/">&#8220;cut loads&#8221;</a>, I had a sick idea.  What would happen if you did this with either the much maligned Taurus &#8220;Judge&#8221; or a M6 survival rifle? Both of these take the .410 sized shotgun shell, which is marginal for self-defense as is. I don&#8217;t expect the load to be a bear killer, but it might be something to try in desperate times. </p>
<p>I don&#8217;t own a Judge, but I&#8217;d be interested in seeing someone try this. (Viewing from a safe distance, of course!) </p>
<p>The load would be jumping the gap between the cylinder and the barrel, and that worries me. I&#8217;m also unaware if the judge has a forcing cone in the revolving cylinder. The whole deal might actually engage the Judge&#8217;s rifling, so the results might be pretty interesting. </p>
<p>Of course, someone had my <a href="http://dcshooters.com/showpost.php?s=46f4184e0d91f2847dacab337554c1ec&#038;p=186073&#038;postcount=18">same sick idea first.</a> He didn&#8217;t try it either. He&#8217;s worried about the gap and the  forcing cone too, and afraid there would be a barrel obstruction. But every non-muzzle-loading shotgun since before the Great Depression has a forcing cone and if it caused all sorts of issues with cut shells, I think we&#8217;d see a lot more broken guns.</p>
<p>If I can ever get a Judge in good shape south of $150 or so and can round up a high speed camera or two and a very long string, you will be sure to see the results published. Just don&#8217;t hold your breath.</p>

			<content:encoded><![CDATA[<p>a/k/a &#8220;cut shells&#8221; or &#8220;ringed load&#8221; or &#8220;ringers&#8221;. </p>
<p>Apparently this was an old Depression era trick one could do in the field to convert a birdshot load into a slug. It&#8217;s easy to do outdoors with a pocket knife and has historically been used to poach deer during waterfowl season. When a shell is cut in this way the upper part of the hull keeps the wad and shot all together from the barrel to the target. The drawback, besides the safety issues, is that the you need to load these as a single shot. Also, waterfowl are generally hunted nowadays with steel shot. There&#8217;s plenty of skeet loads still on the market, though.</p>
<p><a href="http://standardmischief.com/blog/wp-content/uploads/cut-shell.jpg"><img src="http://standardmischief.com/blog/wp-content/uploads/cut-shell-300x165.jpg" alt="A still from the linked movie that shows a shotgun shell after modification" title="cut-shell" width="300" height="165" class="aligncenter size-medium wp-image-1478" /></a></p>
<p>This is something I&#8217;m glad to know about, but not too eager to try. Still, I&#8217;ve highlighted this video by <strong>Iraqveteran8888</strong> because it&#8217;s about the clearest demonstration I&#8217;ve seen from something I&#8217;ve only heard rumors and hearsay about. </p>

<p>As a commenter stated over on the youtube page, &#8220;There ain&#8217;t no school like old school.&#8221;</p>
<p>Here&#8217;s another vid from the same source about improvised slugs made from shotshells. The improvised brenneke slug made with a drywall screw and a fishing sinker is cool, but I&#8217;m not sure I&#8217;d try it. </p>

<p>Here are a few more links I managed to search-fu up from around the web about &#8220;cut shells&#8221;. None of them are as good as the videos above though.</p>

<p><a href="http://thehunterslife.com/forums/printthread.php?t=627">http://thehunterslife.com/forums/printthread.php?t=627</a></p>
<p>This last one is a copy of an article about cut shells in an NRA publication<sup>1</sup>. E. H. Harrison found that the practice actually <em>reduced</em> chamber pressure, but please note that the shells used were all paper hulled &#8211; none of which are on the market today. Nowadays our litigious society, not to mention backlash from advertisers, would make an updated version of this article impossible in mass-market media. Too bad, as I&#8217;d really like to see the results with modern barrel pressure measurements and various choke settings.</p>
<p><a href="http://www.hunt101.com/data/500/003175.jpg">http://www.hunt101.com/data/500/003175.jpg</a></p>
<p>Be cautious with plastic shotgun shells. All the reloading manuals caution against working up your own recipes, unlike when reloading the metallics. I&#8217;ve always assumed that this is because the plastic hulls do not show the same signs of over-pressure like brass does. It would be easy to get into trouble, even using factory loaded shells, by say dumping out 3/4 ounce of lead shot and then gluing in a 1.25 oz. sinker.</p>
<p>I&#8217;d be remiss if I didn&#8217;t note the tremendous price difference between mass-marketed skeet loads and hunting slugs, but please don&#8217;t do this to save money. In fact, don&#8217;t do this.</p>
<p><sup>1</sup> Unknown issue month and year. If you know, please leave a comment.</p>

			<content:encoded><![CDATA[<p>Not here, over at <a href="http://jovianthunderbolt.blogspot.com/2009/11/my-1st-deer-evah.html">New Jovian Thunderbolt&#8217;s place</a>, his first.</p>
<p>My first was a yearling buck, and I nailed it with a projectile in the &#8220;<a href="http://www.google.com/search?q=35000000+grains+in+pounds">over 35,000,000 grain</a>&#8221; class, if you know what I mean.  There I was, minding my own business when Bam!  My first hunt ended on a successful note, with the meat already tenderized even.</p>
<p>A passer-by wanted it, but I parleyed a half steak^H^H^H stake into skinning lessons.  After showing me where the scent glands were and removing the skin and guts, he quartered the meat with a sawzall.  (This is not something I&#8217;d do nowadays because we cut right down the spine.  Prions scare me, so avoiding brain and spine matter seems prudent.)</p>
<p>I took mine home and brined it in a few 5 gallon buckets in the fridge.  That weekend, not knowing any better, I took a hunk of meat right from the tenderloin and ground it up in the Cuisinart.  I mixed it about 5 to 1 with some pork sausage, and that made some pretty amazing bambi burgers. </p>
<p>Yea, it was taken out of season by accident, and possession of a member of the state&#8217;s herd of deer without a permit seems to somehow be illegal, but on the flip side, I&#8217;m pretty sure the state would balk at paying for the damage the deer that it asserts it owns caused against my personal property. </p>
<p>Besides, I already managed to take care of all the incriminating evidence.</p>

			<content:encoded><![CDATA[<p>Apparently there are shortages of the liquidÂ version of Tamiflu, so the CDC has <a href="http://www.cdc.gov/H1N1flu/antivirals/mixing_tamiflu_qa.htm">published a handy recipe for whipping up a batch</a> for your kid that has issues swallowing pills.</p>
<p>I find this interesting because it already takes, starting from scratch, six years of study nowadays to become a pharmacist in the US. While they them may be able to technically compound at that point, I believe that many go on and take on additional training to specialize in that branch of practice. </p>
<p>In fact, if I had to wager, I&#8217;d bet that compounding without a licence was illegal, (but I don&#8217;t carry two lawyers around in my pocket along with the entire US and Maryland state code, so don&#8217;t take this as legal or medical advice)</p>
<p><strong>The Brotherhood and Sisterhood of the Collective Compounding Pharmaceutics weigh in: </strong></p>
<p>I originally got wind of this story via <a href="http://m.lifehacker.com/site?t=mdOWoOHMAx2wFTn0nh0Tbg&#038;sid=lifehacker">Lifehacker</a>, where there&#8217;s this comment from a member of the Pharmacist Guild:</p>
<blockquote><p>@idleuser: I completely agree. I&#8217;m a pre-pharm student that works part time as a pharm tech and there&#8217;s no way we would recommend patients make their own Tamiflu suspensions. Half the time they can&#8217;t even take the correct amount of pills. None of the chain pharmacies around our area compound though. Our store and maybe a couple other local pharmacies do regular compounding. I would urge people to find local pharmacies that can compound Tamiflu for them instead of taking risks with their health or the health of their kids.</p></blockquote>
<p>here&#8217;s a more useful comment further on down the page:</p>
<blockquote><p>Alot of the Tamiflu coming from pharmacies is in capsule form from the Strategic National Stockpile. These are 75mg capsules only. For most kids under age 10, 75mg is too much; so the above method doesn&#8217;t work for them.</p>
<p>For patients mixing Stockpile-supplied drug from home, my state&#8217;s Health Department recommends mixing the powder from a full bottle of ten 75mg Tamiflu capsules with 50mL fruit juice. This makes a 15mg/mL solution.</p></blockquote>
<p>I&#8217;d say that if you can&#8217;t multiply 75 mg times 10 and then divide the results by 50 mL, if you were never any good at word problems and don&#8217;t have or can&#8217;t purchase something to measure liquid in cubic centimeters, then perhaps you should leave the math and mixing to a compounding Pharmacist.</p>
<p><strong>Cranky Consumer</strong></p>
<p>Also, someone at <a href=http://consumerist.com/5402810/you-can-make-your-own-liquid-tamiflu-at-home">Consumerist</a> is angry that a chain pharmacy didn&#8217;t volunteer information that they can actually do compounding inhouse right off the bat. I&#8217;d say the guy was lucky he was offered that as a solution at all. I once took a prescription that required compounding to a pharmacy on a Friday before a holiday weekend and was not only told they did not do the compounding there, but that the one store that they did do the that was already closed for the holiday. I was more upset at my physician that handed me a Rx that I could not read. Had I done so, I&#8217;d have asked her to allow the pharmacy to give me two tubes of ointment and a stir stick. I eventually got my ointment, and I was just charged my usual copay instead of an expected premium.</p>

			<content:encoded><![CDATA[<p>How many safety violations can you spot? While this looks like a &#8220;here, hold my beer and watch this&#8230;&#8221; moment, there are no famous last words spoken. He&#8217;s either got stainless steel balls or has already drunk too much. The classic line here is &#8220;..they only blow up in Hollywood&#8221;.</p>
<p>I understand what he&#8217;s doing, you spray a huge amount of inert CO2 liquid into the gas tank that is both heaver than air and will displace all the oxygen. The MIG welder too, also sprays out CO2 as a gas (If, of course you haven&#8217;t forgotten to turn the gas on first). If there&#8217;s no oxygen, there can&#8217;t be a fire or explosion (as long as everything works out as expected). Dave also knows what he&#8217;s doing. Note the cardboard placed beside him to keep the wind from blowing away the shielding gas.</p>
<p>If he wanted to score the safety violation <strong>hexfecta</strong>, however, I suppose he should forgo the welding mask altogether and just closed his eyes before pulling the trigger. I&#8217;ll confess to doing that before when I&#8217;ve only needed a quick tack weld or three. That welding mask is the only piece of equipment he <em>isn&#8217;t</em> misusing. Note how he carefully places the fire extinguisher completely out of reach.</p>
<p>I&#8217;ve got an urge to mail him some <em>JB weld</em> or a pair of jack-stands.</p>
<p><strong>Weld fuel tank with gas in it</strong> 3:24 min.</p>

			<content:encoded><![CDATA[<p>Here I&#8217;m writing a big file full of zeros that I will, on my next step, mark as deleted. All the space that was taken up with that huge file will still exist, but as Gigabytes and Gigabytes of free space filled with zeros. It should all gzip down to a compact archive. I&#8217;m using the Linux command line to &#8220;Ghost&#8221; or &#8220;clone&#8221; an exact image of my laptop as a baseline for incremental backups. I had no idea I&#8217;d need to leave the thing all day though.</p>
<p>You can probably do <a href="http://www.linuxquestions.org/linux/answers/Applications_GUI_Multimedia/How_To_Do_Eveything_With_DD">almost any device I/O thing in the world with dd</a>, but you have to be careful. Despite what anyone might tell you, dd stands for &#8220;destroy data&#8221;. Screw up the odd syntax and you&#8217;ll copy the factory fresh formatted partition all over top of your backup file.</p>
<p><code><br />

<p>Look at that speed! The SATA was running at a staggering  0.0109375 Gigabits/second, which is about 137 times <em>slower</em> than the max rate of 1.5 Gigabits/second for first generation SATA . Something is way wrong here.</p>
<p>So it took 12+ hours to create the file and only a second to erase it. I&#8217;m pretty sure at least part of the issue here is that I used a ridiculously small block size of 1 KB and did that 58,970,800 times in a row. We&#8217;ll see, as next run will use half of my RAM as a block size. </p>

<p>So 15.3 (MB / s) = 0.11953125 Gb / s, which is both much faster and still a less than a tenth of advertised speeds. If this was my broadband connection I&#8217;d be on the phone to customer support by now.</p>
<p>I see I did have an error for the second run. I used a blocksize of half a MB instead of half a GB ( bs=512K instead of  bs=512M). Well that&#8217;s something to try for next week.</p>

			<content:encoded><![CDATA[<p>If you&#8217;ve ever had to hand carry a package to the FedEx drop-off point and you have half a brain you&#8217;ll know that as soon as the staff scans the barcode on the label, the package becomes their responsibility. You would also assume that if someone dropped off an item and it somehow failed to be scanned, and that package dropped into a black hole, FedEx would assume that such a package never even existed. Therefore if the package is especially time-sensitive (like perhaps you are willing to spend a bit of scratch to get it there overnight), or valuable, you&#8217;d probably want to make sure that the staff actually scan the package before you let it out of your sight. Unfortunately at all the drop-off locations I frequent, this is harder than it looks. In fact, in my experience <em>none</em> of these work:</p>
<blockquote><p>
	Hi. Could you scan my package?<br />
	Would you scan my package please?<br />
	Please scan my package. No, I don&#8217;t mind waiting my turn.<br />
	I need you to scan my package first before I leave.<br />
	No, don&#8217;t get up out of your chair. Just lift that wireless scanner that is by your right hand, point it in the general direction of this very important package that I&#8217;ve placed<em> right here in front of you on the scale</em>, and pull the trigger.
</p></blockquote>
<p>I&#8217;ve had a package that I insured for several thousand dollars that had to go out that night for an early AM delivery. Because of the hour, I drove the package right to the airport&#8217;s staffed FedEx point and got into a shouting match with fscking asshole behind the counter because he did not care to scan the package in front of me. Then a &#8220;manager&#8221; swung by and told an obvious lie to cover for his minion. By that time I was on the phone with FedEx. I asked if there was any special magic words I needed to say to get the hired help to do their jobs without making the whole deal a pain in the ass. They were no help.</p>
<p>On a different trip, I discovered the secret. Someone in front of me in line said the special magic words, which are as follows:</p>
<blockquote><p><strong>I need a receipt for this package.</strong></p></blockquote>
<p>That&#8217;s it. They need to scan the package to give you a receipt. Absolutely no stress, no issues, and no attitude.</p>
<p>While comments are open, I&#8217;d especially like to invite comments from those who work at FedEx, either as management/customer service/public relations employees, or front line workers. Maybe there&#8217;s another side to the story on the &#8220;i don&#8217;t wanna scan the packages in the presence of my customer&#8221; issue.</p>

			<content:encoded><![CDATA[<p>Just a little something I whipped up one night before the long drive home. Yea, after losing my 5 minute commute, I&#8217;m starting to get into pre-recorded talk shows. I&#8217;d have started this post a little differently, but 2003 called and they wanted their podcasting howto post back&#8230;</p>
<p>Anyway, here it is:</p>
<p><code>curl -LO $(curl "http://www.blogtalkradio.com/gunnuts.rss"|egrep -o "http://[^ ]*mp3"|uniq|head -1)</code></p>
<p>The first curl command uses the <strong>L</strong> option to allow the request to be redirected with a 3XX response code. Blogtalkradio.com does this.</p>
<p>The <strong>O</strong> option just assigns a filename based on the original rss feed URL (sans path). This works well unless you get someone <a href="http://market-ticker.denninger.net/">clueless</a> who names their files like this:</p>
<p><code></p>
<p>http://www.blogtalkradio.com/MarketTicker/2009/05/18/TBA.mp3</p>
<p>http://www.blogtalkradio.com/MarketTicker/2009/05/11/TBA.mp3</p>
<p></code></p>
<p>I&#8217;m not going to explain the regex and remainder except to say that the -1 can be changed to a higher number to get more shows unless everything goes foobar because Karl named his files with exactly the same name.</p>
<p>Oh, and the files just end up in your current working directory, and you&#8217;ll have to get out of it if you want to cleanly unmount your flash card, but you knew that already.</p>
<p>You&#8217;ll need to get curl though. N00buntu users could use something like</p>
<p><code>$ sudo apt-get install curl</code></p>
<p>but if they really are n00bs they&#8217;ll probably use the GUI tool to get the job done, and then never touch the command line and get their podcasts using Amarok or something. Nothing wrong with that, it&#8217;s just that you are not the audience I&#8217;m writing for.  The audience I am writing for will find their way here using the &#8220;search engine friendly&#8221; URL.</p>
<p>Oh and since I&#8217;m new to this podcasting stuff, I have to ask. With the proliferation of mp3 players like the iPod shuffle that don&#8217;t have a display, shouldn&#8217;t we be starting our broadcasts with &#8220;gun nuts #54 for May 27th&#8221; instead of &#8220;<a href="http://www.gunnuts-tng.com/">Goooood evening ladies and gentlemen&#8230;</a>&#8220;? That would allow a user to shuffle through a bunch of shows to easily find the one he has not heard yet. Much nicer if the shows don&#8217;t all sound the same until a half a minute in.</p>
<p>Thanks for making my commute a bit more interesting, everyone.</p>

			<content:encoded><![CDATA[<p>I did the BWI loop trail the other day. It&#8217;s detailed <a href="http://bikewashington.org/routes/bwi/index.htm">here</a> and <a href="http://www.google.com/search?q=bwi+trail">elsewhere</a>. Because working at the startup really cuts into my workout time, I had the same second-day nausea and loss of appetite from having a hugely calorie deficient bike ride. With regular exercise this does not happen, but you gotta bike and bonk a bit after slacking off.</p>
<p>I&#8217;m trying to get some motor-vation today but all I can manage is this post. The problem with the first link above is that there&#8217;s no data that would let you know how old the info is. Blogs, or at least mine are immune because every post is dated.</p>
<p>I did this trip about a year ago, and I&#8217;m happy to report that someone has put up signs so it&#8217;s a bit easier to keep on the loop.  I&#8217;ve felt the urge before to spray-bomb the entire loop in orange marker paint. Still, in my GPS notes that follow, I&#8217;ve tried to mark out the major turns to keep you on track.</p>
<p>It was a nice day yesterday. The average &#8220;serious&#8221; speed cyclists on the trail were as rude as ever (I swear, it&#8217;s like the bastards think you are fscking Lance Armstrong and the only way they can beat you is to sneak up and pass you silently and suddenly). These idiots are probably only eclipsed by the typical <em>Young Hippie Bicycle Fanatic</em> (of Critical Masshole fame). Motto: &#8220;share the fucking road except for those god-damn pedestrians!&#8221;</p>
<p>Now you know why I like to keep off the beaten track.</p>
<p>Anyway, I ought to make a clue sheet or something. Tough. Assume the following is going around the loop clockwise:</p>
<p>39.16260,-76.66355  &#8211; Start and end point. Parking. Good plane-spotting area.</p>
<p>39.15938,-76.68412 &#8211; A 7-11 with gas pumps. All the usual stuff here but be extra careful crossing the high-traffic street. Better yet, stop here first, before parking at the trailhead.</p>
<p>39.17782,-76.69032 &#8211; Left turn here</p>
<p>39.17822,-76.69305 &#8211; Right turn here</p>
<p>39.19095,-76.69146 &#8211; Left turn here</p>
<p>39.19035,-76.68082 &#8211; Bear left. Do not bear right and cross the bike-bridge over Aviation Loop unless you want to do the dead-end spur that goes to the main terminal.</p>
<p>39.19132,-76.68034 &#8211; If you want, you can go off the trail at this point, and go left on Elkridge Landing Road for 550 feet, (thereâ€™s a trail on your side of the road, no need to cross), to a McDonalds (food, free refills, tap for water at the soda fountain) You are about half-way around the loop at this point.</p>
<p>39.19349,-76.67067  &#8211; Bird watchers might see an Emu or two behind the chain link fence.</p>
<p>39.19389,-76.66678  &#8211; Not a lot of plane action, because of a less popular runway, but otherwise an outstanding overlook.</p>
<p>39.19626,-76.66509 &#8211; Farm. Horses. Sculpture in stainless steel.</p>
<p>39.19478,-76.65619 &#8211; Rail track crossing</p>
<p>39.16141,-76.64547 &#8211; Decision time. If doing the loop clockwise, veer off to the right at this point. If going on to the <a href="http://bikewashington.org/routes/bwi/index.htm">Baltimore and Annapolis Trail</a>, then go ahead and cross the bridge across I-97 (a/k/a Glen Burnie Bypass).</p>

			<content:encoded><![CDATA[<p>If you&#8217;ve done any bash shell scripting, you may have come across the need to write data to a temporary file. However, a well-written script should take in the possibility that it will be run more than once at the same time, (the unices being multi-tasking and all that), so you will want to make sure that different processes don&#8217;t all write the same data to the same hard-coded /tmp file.</p>
<p>One of the standard ways to do this is to use the bash built-in variable &#8220;<strong>$$</strong>&#8220;, like so:</p>
<p><code>echo $data-to-log &gt;&gt; /tmp/"$$"log.file.txt</code></p>
<p>And that usually works fine, as long as only one person is running that script per login account. You will, however, have issues if you run the script from the console at the same time that the script is run from your crontab. Ask me how I know.</p>
<p>The <a href="http://techpulp.com/2008/12/how-to-get-the-pid-of-current-bash-shell-script/">common</a> <a href="http://tldp.org/LDP/abs/html/internalvariables.html#PROCCID">misconception</a> here <a href="http://www.labbookpages.co.uk/software/bashTips.html">is</a> the <a href="http://en.community.dell.com/blogs/hpcc/archive/2008/04/21/strace-mpi.aspx">idea</a> <a href="http://www.math.ucdavis.edu/~zjohnson/doc/Adv-Bash-Scr-HOWTO/variables2.html">that</a> the <a href="http://www.thing.dyndns.org/debian/bash.htm">bash</a> <a href="http://www.faqs.org/docs/abs/HTML/variables2.html">built-in</a> <a href="http://www.franzone.com/2007/09/23/how-can-i-tell-if-my-bash-script-is-already-running/">variable</a> &#8220;<strong>$$</strong>&#8221; <a href="http://qref.sourceforge.net/Debian/reference/ch-program.en.html">holds</a> the PID (process ID) of the script itself. That is <span style="text-decoration: underline;">not</span> true.  It&#8217;s actually the PID of your bash shell. Therefore running your carefully crafted script more than once at the same time can fsck-up your script output.</p>
<p>A better way, and my standard mischief, is to do the following. First, somewhere up near the top of your shell script create a variable that is unique, like so:</p>
<p><code>uq=$(date +%s-%N)</code></p>
<p>backtick people can use this:</p>
<p><code>uq=`date +%s-%N`</code></p>
<p>but I like to use the &#8220;<strong>$()</strong>&#8221; out of habit because it makes it easier to nestle the commands. Besides, after too much caffeine and staring at a LCD all day, those backticks can be a bit hard to see.</p>
<p>Then, we use this variable in place of &#8220;<strong>$$</strong>&#8220;, like so:</p>
<p><code>echo $data-to-log &gt;&gt; /tmp/"$uq"log.file.txt</code></p>
<p>What we are doing here is running the <strong>date</strong> command, and having it show the number of seconds since the Unix epoch back in 01jan1970. Then, we add a dash and the number of nanoseconds. We assign the results of that command to the variable &#8220;<strong>$uq</strong>&#8220;. The end result is that unless the two scripts run this command at exactly the same time (probably impossible even if you were trying), the variable <strong>$uq</strong> is going to be a wholly unique number. When you use this unique number in a filename you can be pretty sure you won&#8217;t be clobbering existing data by overwriting an existing file.</p>
<p><span style="font-family: Arial,Helvetica,sans-serif;"><span style="font-size: x-small;"><strong style="background-color: #a0ffff;"><br />
</strong></span></span></p>
