  1. Re:Don't *need* a rack on Rack Mounted PCs for the Home User? · · Score: 4, Insightful

    Yeah, well, sometimes you get what you pay for :(

    Note that my experience comes from both working in a datacenter (a competitor to Rackspace, won't say who), and from having a home rack built out of that wire shelving. There are pros and cons to both sides.

    The biggest pro, of course, to the cheap white box and wire shelving way is the cheapness factor. The problem is that this is only an advantage while you have a lot of extra space in the data center. You can only get 9 or 12 white boxes in a rack stacked vertically, you can get 42 1U servers in a single rack. 3 times the density, basically. Plus, in my experience with our legacy cheap whiteboxes, they are far more likely to have hardware failures (power supply, motherboard, etc.) than the higher class hardware (mostly IBM, some Dell and HP). Hard drives fail in everything, but the whiteboxes are a pain in the ass to take apart to replace them. The rackmount servers open right up, and everything is right there where you can get to it. Also, the nonserver motherboards and bioses that were put in the whitebox have various issues with our automated build systems (varying NICs, some supporting PXE boot, some not, different array controllers, etc). You can control some of this by buying the same parts from the same vendors, but consumer systems don't have the build stability that server oriented systems do. Even if you are buying exactly the same model, you can find components (and drivers!) changing from one revision to the next depending on where the manufacturer got the best deal.

    Now, as to the home environment, like I said, I have a wire shelf rack, with a bunch of different stuff on it (Suns, PCs, Powermacs). The main reason I am probably going to buy a real rack for the new house I just bought is flexibility. You can't easily move shelves around or add shelves to one of those wire units without taking the whole thing apart. If you only have tower systems, all exactly the same height, this is probably not a big deal. You just make all the shelves the right space for the tower systems, and leave them in place. But if you have a mix of stuff, and you want to maximize your space usage, you really want to put stuff horizontal, each on a separate shelf. This is when a real rack comes into its own. There are a variety of shelves available (some that slide out, some statically mounted, etc). Adding or moving a shelf is just a matter of 4 or 6 bolts. Most server class hardware has available rackmount addons (all of my Suns do). Another factor is cable management, currently I have a mess of wires all velcroed together... good racks come with cable management built in, and it is usually fairly cheap to add to a rack afterwards even if it doesn't come with it. And note that if you shop on ebay, or can find a good local remarketer/recycler (one who buys stuff from closing companies), then rackmount hardware and even the racks can actually be cheaper than buying wire shelving brand new. My 7 foot tall wire shelving unit cost me $350 to build... I have seen full racks, with side panels and everything, for $150 or so on ebay. What kills on these things is the shipping, so finding a local remarketer or ebay seller like another poster mentioned is definitely a good idea. You could double the price of a rack with the shipping charges.

    Don't give up completely yet!

    There are people who agree with you, and are working on something similar to what you are asking for. Note that I am not an expert on this, but I thought it was an interesting and valid question, as I have a penchant for running Linux on old/retired (mostly non-x86 though) hardware. I am a professional sysadmin, so I don't think too much about getting something up and running on a weird machine, as that is what interests me. But I am also aware of the ease of use/installation issue, because I have supported Macs and Windows machines for years, and used Macs at home for years as well. You can't beat the "stick a CD in the drive, click a button, walk away, and when you come back there is a working system" model of installation.

    Anyway, for a project that seems to be aligned to what you are asking for, you might want to check out the RULE project. I just found out about them recently, and I don't know how up to date they are, but they seem to have similar goals to what you have described. They claim that one of their installers can run in 12Mb of RAM, and the other in 6Mb. They install mainly a stock copy of Redhat, but with the package list stripped down to make a smaller profile. In addition, it appears that they are doing some work on the Kdrive X server, which is a very small XFree86 replacement.

    Unfortunately, my lowest spec Intel machine (a p133 laptop), that I used to test and run things to make sure it worked on slower machines, was stolen when somebody broke into my house, so I have no way at the moment to test the RULE project out. Most of my other machines are SPARCs or Powerpcs, so they don't work with this project. You might want to check out your local Linux user group, as in my experience they are usually packrats, and have lots of old machines, and a willingness to help.

    Note that freshmeat started as a directory of opensource unix software. For many people (including myself) that is still it's primary function. There are already a million search sites for Win32 free and shareware applications; there is no need for freshmeat to turn into another one.

    As to windows opensource software, the most important entry, Cygwin , is there. Additionally, there are a lot of other crossplatform programs that happen to compile and work on windows listed under the Trove Windows category.

    And a somewhat facetious aside... Windows NT/2000/XP whatever, despite their somewhat POSIX compliance, and the availability of Cygwin/DJGPP, are still not an acceptable Unix to some of us (meaning me :). The primary lack is that of a decent terminal (one that supports vector fonts, full VT100 emulation, easy window size changes, etc.). Note that I am talking about a local terminal... for remote connections, you can use Putty, which is relatively decent. The two "best" ways that I have found to get a decent term on Windows are:

    • Install Cygwin, setup up sshd and ssh in to localhost with Putty.
    • Install X11 of one kind or another, and use an XTerm
    I don't find either of those a very satisfactory or clean solution, but they can make working on Windows a little more livable to Unix head like myself. Note that Mac OS X has a decent terminal application installed by default, /Applications/Utilities/Terminal.app, which supports TrueType fonts, multiple encodings, easy window resizing, saved settings, etc. This makes Mac OS X a much more usable Unix system out of the box.
  9. Re:Sure it's promising on Working Bayesian Mail Filter · · Score: 1

    Note that Bayesian mail filters use a probabilistic analysis of the word distribution in the email you feed it during the training process in order to classify email as spam, or nonspam (and in the case of popfile, any other category you want to create).

    As long as the spam you receive remains sufficiently different from the nonspam email you receive, Bayesian filters should still flag it properly. To put it another way, it doesn't test for the presence of specific words to categorize as spam (like SpamAssassin does), instead it uses the probability database built up during the training process to determine how similar the prospective email is to either the spam you have received and trained upon or to your regular email that you have trained upon. Thus it is much less susceptible to spammers changing their wording in order to defeat the filter.

Privilege separation is just the right way to code network daemons -- postfix does it, apache does it, courier imap does it, qmail does it -- and now, openssh does it.

Plus, when I was doing photo retouching for a living, $150 was the target price for a single small retouching/restoration job (about 1 1/2 hours of work).
    2. Some people aren't satisfied/can't work with a point-and-shoot camera. A decent, professional level digital camera, that works with existing pro lens systems is way more than $600... the Nikon D1x is over $5000. If you don't need the flexibility of a full digital system, but still want the flexibility of interchangeable lenses, it is still cheaper to buy an N90 or N100, some decent lenses, and a film scanner (total of around $1500-2000).
    3. Plus, while cameras like the D1x are able to rival some 35mm film stocks in quality, they aren't even close to the quality of a 2-1/4 or 8x10 transparency.

    So, basically what I am saying is that there are still a lot of people scanning from transparencies, and that some really good retouching tools (plus being able to deal with large files) are worth the price of Photoshop.

    If all you ever have to deal with are teeny RGB images targeted to the web, by all means, use the GIMP... it'll get the job done.
