  1. Re:Surprised they let him on Record-Breaking Model Rocket Launch Set For April 25 · · Score: 2, Informative

    Well, with a maximum altitude under 5000 feet, this guy's not going for performance, he's just putting a scale model up in the air high enough to say it flew. High performance means high propellant mass fractions (where up to 90% of the launch weight is propellant) and almost certainly multiple stages. This rocket has an 18% propellant fraction and is single stage. It will look very cool coming off the launchpad and that's all it needs to do.

    The government gets interested when you start heading for 50,000 feet, 100,000 feet, or higher. The other thing the government gets interested about is guidance systems on rockets. If it's a self-stabilizing rocket that goes up and down with no guidance system, just follow the FAA rules to make sure there are no aircraft in your flight envelope and the government doesn't really care.

    No, the gyroscope effect of the wheels on motorcycles and bicycles is minimal. The dynamic stability of two-wheeled vehicles occurs because the point of contact on the front tire is behind the axis of rotation of the steering head. So as the bike moves forward, the front tire is being "pulled straight" and can be easily maintained on a track by the rider.

    If the gyroscope effect was significant enough to keep a motorcycle upright, it would prevent leaning the vehicle over during turns, which doesn't happen.

    Nobody expects a recent graduate to write a kernel or a banking app!

    Even more precisely, nobody expects a recent graduate to really know how to write good enough code. That's something a new graduate should expect to learn in their first three to six months on the job.

    The expectation is that you already know how to learn languages. The issue with only learning C, C++, and Java is that they all use a related syntax and they are all statically typed. This is not enough variety. I would suggest that before you hit the real world you learn at least one language that isn't the same. Python, Ruby are excellent choices at this time. Lisp, Haskell, Erlang are also possibilities if you'd like to explore functional programming.

    Something else a good developer is usually expected to do is adapt to the coding conventions in the current project. I have found, however, that many if not most developers are completely and unable to adapt to team conventions. They have their "best way" and can't write code any other way.

    If I can provide one piece of advice to help you with your success in programming: remember that conventions are not for you. They're for the people who come after you. Having consistent and readable code is more important than whether or not you like indentation with tabs or spaces.

    Technically, firearm ammunition doesn't explode, either. But they regulate that.

    Not really. Like other deflagrating substances (including dry ice and coarse crystals of ammonium perchlorate), you have to ship ammunition via ground transportation with an ORM-D designation, but there are no federal regulations on the transport of ammunition that are more restrictive. There are a lot of state and local regulations regarding the purchase of ammunition that imply additional restrictions on shipment (seller must have copy of photo id), but that's not the same as regulating shipment.

    Notably, most of the state and local regulations that put additional processes around the shipment of ammunition do not further restrict the purchase of smokeless powder (the actual deflagrating substance) or primers (containing an actual explosive) in the same way. So if I lived in LA, it would be very difficult for me to purchase ammo off the internet, but not to purchase separate brass, powder, bullets, and primers.

  7. Re:In defense of the BATF? on Rocket Hobbyists Prevail Over Feds In Court Case · · Score: 1

    It's relatively easy to synthesize ammonium perchlorate from sodium chloride (table salt) and ammonium chloride (many uses from snowmaking to candy making to cattle feed supplement to expectorant). Build a glass reactor vessel, buy some anodes off eBay, use a car charger and several days to force the sodium chloride table salt to sodium perchlorate in solution, destroy any residual sodium chlorate using one of a number of reactions, dump in ammonium chloride, collect ammonium perchlorate as the precipitate. The even more exciting potassium perchlorate is equally easy to make and you can make ten pounds for less than $10 in supplies from Home Depot (electricity costs will vary by location in the US). One bag of potassium chloride and your reactor can make as much potassium perchlorate as you have electricity to put in and time to pull out of it.

    It's much more difficult to try to extract the ammonium perchlorate or potassium perchlorate from mixed and cured rocket motor grains. In the rocket motor grain, the APC or PPC has been mixed up with aluminum powder, an accelerant or inhibitor, one or more stabilizers and the composite resin, which is chemically similar to epoxy. You might as well try to get the glass fiber back from a finished sailboat hull.

  8. Re:Nice -- more of what we already knew on Smart Immigrants Going Home · · Score: 1

    I think you misunderstood my posting. I don't blame Bush II for the economic disaster. He bears some of the responsibility for it, sure, but there's blame to go around for a disaster this big. Many other people contributed to the problem over the last 15-20 years to try to "solve" several necessary down cycles and thereby create a world-wide economic collapse, and Bush II only had eight years of watching the snowball grow into the avalanche that can be laid at his feet. Just about the only person who can't be blamed for the disaster is Obama. So far. We'll see if his cautious manipulations of the banks can stabilize things. If not, his name will be added to the list and he'll lose in 2012.

    My posting was simply to state two things: that the CRA had absolutely nothing to do with bad loans and most certainly had nothing to do with what's going on now and that your mental contortions to avoid putting any responsibility on Bush II were nonsense.

    The CRA didn't tell banks to loan to people without incomes. It said to loan to people in bad neighborhoods using the same loan criteria about the individual as you do in good neighborhoods. The idea that there might be money made from high-interest loans to bad risks did not come from the CRA either. Also, the idea that it wasn't necessary to check for income or assets only appeared once the housing market was rising fast enough that all loans were always above water. Again, nothing to do with the CRA. Finally, the idea that mortgages could be bought and sold in bundles that supposedly reduced the risk of individual defaults was a regulatory failure and had nothing to do with the CRA.

    Basically, anyone telling you that the CRA had the smallest thing to do with our current economic problems is completely and utterly full of shit. They're wanting to put blame on Democrats for something, and the CRA 1) looks like sub-prime mortgages and 2) was pushed by Democrats. Look deeper at the CRA and it's simply forcing good business practices onto elitist snobs (most of whom were Democrats) who didn't want to loan money to the lower-classes.

    Yes, Bush II will go down in history as the worst president ever. No, he's not the only person to blame for the disaster. He is a very visible person to blame, however, and deserves pretty much all of the barbs thrown his way. IMHO, anyway :)

  9. Re:Nice -- more of what we already knew on Smart Immigrants Going Home · · Score: 4, Insightful

    Um, the CRA is a red herring.

    The loans covered by CRA tended to have the same risk profile as other bank loans.
    "liar loans", "no income, no assets loans", etc. almost entirely came from institutions not covered by CRA.

    The rest of your list is not any better.

    You completely missed Christopher Cox's incompetent regulation of financial institutions at the SEC, Alan Greenspan's ill-advised attempt to keep spending up by keeping interest rates near zero for most of a decade, Bush begging Americans to "keep spending" after 9/11, and the real original seed of the current disaster, which was a series of moves to deregulate banks that occurred during Bush I and Clinton leading to the creation of credit default swaps, the securitization of debt, and all sorts of other really bad ideas.

    But it was nice of you to try to make Bush look a little less incompetent. The worst president in history still needs a kind word every once in a while.

    That's the result of a settlement with the class. As soon as the judge certifies the settlement, it applies to both parties, including the class, and can bind members of the class from subsequent litigation.

    The judge's certification is supposed to verify that the various obligations of the settlement are in the fiduciary interest of the class and the plaintiff, to prevent the class lawyers from writing a settlement which only benefits themselves, for instance.

    So far, when I've ended up on a Google books search result, the book has usually been in stock at Amazon and bn.com (with helpful links to those pages on the right side of the page). Now, these in-copyright search results are compromised, in that Google pulls random pages from the viewer so that you can't just read the whole thing.
