    See my followup to your parent article about the real meaning of "soft tooling" vs. "hard tooling".

    To answer your question, stamping punches and dies are typically made from cold-working tool steels that are designed to be hardened.

  2. Re:hard tooling vs soft tooling on How a Computer Case Is Built · · Score: 1
    Sorry, the words "hard" and "soft" do not describe the metals used in tooling. They describe how two different types of punch press machines perform their function.

    "Hard" tooling of sheet metals means making two large pieces of metal, one with a bunch of holes and the other with a matched set of punches. They operate by stamping a blank sheet of metal in a single stroke and producing an entire pierced and formed part. The press can stamp a high quality part out in seconds. Thus, the savings when making a large run of parts.

    "Soft" means that the punches are not necessarily shaped like the holes in the case. They're little "nibbling" tools that a computer drives around like a pair of scissors in the shape of the desired holes. The press has to spend lots of time driving the tool bits around the sheet metal. Thus, the expense when making a large run of parts.

    Making a custom punch and die to stamp a part out of a sheet takes a craftsman a long time, and a lot of effort. Thus, the high startup expense. Changes are also expensive. You can't just slide a set of holes around a big chunk of metal.

    Nothing needs to be "made" for a soft tooling setup. You buy a set of preformed tool bits, load them into the computer controlled punch, and it starts cutting parts now. Thus, the low startup expense. And changes are quick and easy. CNC machines are perfect for making test parts, or keeping production up when the punch and die are being serviced.

    The quality difference between "soft" and "hard" results from the nibbling process used in soft tooling. Nibbling does not make a "clean" cut. Think of it as the difference between a paper cutter making one quick, long straight cut while scissors make many slow, small jagged cuts.

    The "hard" vs. "soft" decision is usually an economic gamble. Will you make so many parts that investing thousands of dollars in a custom punch and die will be cheaper than investing minutes per piece in a CNC machine?

    My first exposure to "decent" quality paint programs was Photoshop LE (packaged free with a scanner.) I found the GUI confusing.

    I then bought Paint Shop Pro on the recommendation of a digital photography book I respected. Again, I found the GUI confusing, but at least the book got me started on what I should be looking for. I think if I had read such a book about Photoshop earlier I'd probably be a Photoshop fan right now.

    I now switch back and forth between The GIMP and Paint Shop Pro. The GIMP does some things better (script-fu is really slick) and PSP does some things better (scratch and dust repair, contrast enhancement.) But I still have to hunt through confusing menus, pop-up toolbar things, etc. I've simply come to expect that any powerful photo editing program is going to have a confusing interface, and that any program is going to take an investment of time to learn. Paint Shop Pro has some hand-holding tutorials that I found to be excellent at getting me up to speed. I'm sure these things exist for the other programs as well.

    Rendering (in Windows parlance) typically means "outputting to a display device." Once you've rendered the data, the only way to get it back out of a window like that is with some really clever GDI tricks. If they're not operated by a person, rendering would be a costly extra step. Why spend the time downloading IMG tags for doubleclick, for example? I seriously doubt they're going to that effort.

    The SHDocVwCtl COM objects provide an InternetExplorer interface for operating IE from within a program. They can request a URL and retrieve it as a Document. They can get tags and attributes from that Document automatically. But rendering the page would be counterproductive if a human isn't there to watch the screen.

    I certainly believe you that they'd use the COM interface to IE. I am sure they examine the attributes of the tags coming back, looking for mailto: URIs. I also believe they'd look at the text surrounding every "@" sign or "mailto:" phrase they encounter, trying to simply determine whether or not they might be part of a valid email address.

    Sorry, but that "don't munge" page is hopelessly outdated, and its advice is useless at best (although I have to admit being highly amused by the "if you munge your address then the terrorists have already won" attitude!)

    Back when the 'net was young, and there was hope for stopping spam before it snowballed out of proportion, it was hoped that this naive "nip it in the bud" attitude might work. It hasn't. Spammers have proven as resilient as cockroaches, and more prolific.

    Keep in mind who is paying for spamming: get-rich-quick losers. There's more than one born every minute. They're typically not successful, but there certainly are a lot of them. By the time one of them has realized they're not "getting rich quickly" and give it up, half a dozen more have started up their own "get rich quick" schemes.

    Legislation, anti-spam hassling, RTBLs, threats, ISP cut-offs, they all serve to shut these fools down one at a time. But the population growth of fools far outpaces the ability to shut them up.

    I agree that address munging "breaks" how things are supposed to work. The reality of spam dictates that many of us have given up how we want things to be, and instead deal with things as they are. I can't afford to fight every stinking spammer in my inbox, and those are the ones that have successfully run a couple of anti-spam gauntlets. Automated spam reporting tools proved useless to me years ago -- and now the anti-spam RTBL sites are busy collapsing. Bayesian filtering has been mostly effective for me so far, but I still find good mail in my spam box. Changing email addresses helped dramatically at home, but is not an option at work. So, if munging helps reduce the spam, it's just another useful tool in my kit. And if you think address munging prevents someone useful from contacting me, you simply have no idea of the depths of my apathy.

    "Address harvesters" in this context are not people sitting in front of web browsers. They are programs, and they are not based on rendering engines such as Mozilla or IE. These programs are dedicated web crawlers that open sockets to web servers, pull in data, recognize a limited subset of tags that represent links to more pages, and attempt to perform character recognition on text strings that resemble valid email addresses. When they find text that looks like this: href="mailto:myaddress@myserver.dom" they've hit the jackpot. These programs don't execute javascript, they don't pull in IMG tags, they simply scan for text strings that smell like foo@bar.baz and follow links that might lead them to more addresses.

    I have noticed that people do tend to forget that there are other schemes for harvesting addresses that have nothing to do with web page encoding or mailto: URIs.

    One of the most productive sources of addresses for spammers are copies of chain letters. You've probably received some sent by well-meaning but clueless relatives. "Here's an ASCII snowball, throw it at your friends!!!" Your friend clicks "Forward", then clicks on every name in her address book. When a spammer gets a bonanza like this, they have not only a To: line containing all the entries in your friends' address book, but all the To: lines contained within that have survived a dozen forwardings.

    Under Linux you can get cheap diversity and very little administration overhead by running redundant servers under two different hardware architectures (Intel + PowerPC for instance). once the kernel has booted the administration of the two machines is virtual identical, but they might as well be from different planets as far as a worm is concerned.

    While it will probably help slow the spread of worms, "diversity" is not a total guarantee.

    I was looking at my Apache logs the other day, and for kicks was looking at a series of attacks from someone who still has Code Red (or Nimda, or one of those other stupid microsloth worms.) The worm itself launched over a dozen independent attacks, testing for many different vulnerabilities in the various versions of IIS.

    If version X.Y of any application has a hole, it has a hole that could probably be exploited regardless of the platform beneath it. Buffer overruns don't go away magically simply by porting the code to PowerPC. Anyone able to exploit it on an Intel Linux server could probably muster up the code required to also exploit it on a PowerPC running OS X as well. A multi-pronged attack would be able to strike multiple platforms. Since we're talking broadband speeds for most of the problems these days, fat binary worms would go almost as unnoticed as the svelte single-platform worms.

    This is, of course, the worst-case scenario. Most defacement hackers aren't going to go to the trouble of generating i386, PPC and SPARC fat-binary worms. But the biggest point of Geer & Co's* report was that a monoculture leads to national security issues. A well-funded, determined, malicious attacker (I hesitate to invoke the "T" word) intent on delivering an internationally crippling blow to the 'net might take the extra time to add exploits for many various platforms and OSes. The weaknesses inherent in a monoculture extend not just to OSes, but to applications as well.
