  1. Re:Why no easy installer? on OpenBSD 3.2 Readies For Release, pf Matures · · Score: 2

    What I don't get is why don't these projects realize the kind of coup they could score by releasing a Mandrake/RedHatesque installer that even the average marketting drone could use to setup a fully operational installation.

    1) Do you really want a "marketing drone" establishing your critical network infrastructure? Average people shouldn't be meddling with the systems that can really make or break a company. This is serious stuff.

    2) The OpenBSD installer really is quite easy when you sit back and think about it. It's basically a well-thought-out shell script with prompts for necessary information. It's also very quick; OpenBSD installations are fast, since there isn't a quasi-stable GUI driving everything. It's also more dependable than a GUI. GUIs are complex from a software engineering point of view, and it is harder to guarantee their function. If you have questions about how OpenBSD goes about it's business...just look a the scripts.

    I'm still just a novice with *NIX...

    Don't let OpenBSD intimidate you, as it can provide a very fruitful learning experience about UNIX systems. OpenBSD really is one of the most directly and thoughtfully documented systems out there (at least for the userland stuff), but it just isn't an in-your-face system like Red Hat. Once the system installs, there is a helpful e-mail sitting in the root inbox, the installation CDs have very good README files, and the 'intro' and 'afterboot' man pages are also good. The OpenBSD website hosts a FAQ and links to mailing list archives that covers many questions for new users.

Form validation and text-field updates are also not a big deal. However, many intranet websites push all this all way too far.

Given that these sites are barely accessible to me (they are annoying as hell), I can't imagine how a person disabled in some manner would deal with them.

    2) most computer systems today always runs multiple threads (i.e. utilization will be good).

    It is true that pretty much all the modern operating systems support treads on multiple CPUs, but I have found that it doesn't guarantee good utilization. Most desktop applications are single-threaded effectively due to the user being single threaded. I saw this while working on a 2 CPU workstation: the second CPU was idle perhaps 90 to 95% of the time.

    This would be different if a specific application were designed to automatically divide work among multiple CPUs, but those sorts of applications are not common outside of image/video editing, engineering, science, and mathematics. Perhaps games will take better advantage of multiple CPUs, but that is probably a little ways off. Servers, especially UNIX ones, will almost always find a second CPU useful, since servers are supposed to be multi-user multi-processing environments.

    Multi-core architectures are naturally appropriate for servers, but I still think most desktop users are best served by one fast processor (even hyperthreading will be largely irrelevant).

    But these days, you can get an Ultra 5 (I think it's being replaced by the Ultra 60 now) for the price of a PC, and it's a real SPARC, so Solaris x86 is less useful for that purpose.

    The Ultra 5 is quite a few years old, now. For the Ultra 5's market, the modern replacements are the Blade 100 (500MHz USIIe) and the Blade 150 (550MHz or 650MHz USIIi). The Ultra 60 (2x 450MHz USIIi) was marketed as an engineering workstation, which has been obseleted by the Blade 1000 and Blade 2000 (2x 1GHz+ USIII).

    The Blade 100 and Blade 150 are inexpensive ($1000 to $2000), but the Blade 2000 is the no-holds-barred version ($7000+). Regardless, even the Blade 100 is well engineered and a good workstation, but it's overall performance makes it suitable for administration and productivity tasks. For software development and real engineering work, the Blade 150 and especially the Blade 2000 are better options.

    I do wish Solaris 9 were free up to two processors, since that would open up basic SMP experimentation to hobbyists who like Solaris.

    One thing that is nice about Solaris is that Sun ensures that there are tangible benefits to each major release. Solaris 8 had a better memory subsystem (among other things). Solaris 9 bundles lots of nice things (among other things). And Sun does it without bringing on the skepticism that Microsoft seems to ignite with each release or EULA upgrade.

    ...buying more expensive, used hardware with an old version of Solaris.

    You don't quite understand. New versions of Solaris, such as 8 and 9, work fine on older hardware. Sun does discontinue support for really old hardware, but they are up-front about it in their release notes. A good example: I run Solaris 8 on an early-90's-vintage SPARCstation 10.

    Also, used Sun hardware is very reasonably priced if you shop around. Some vendors are arrogant and still think they can charge like-new prices, but other vendors are very competitive. If you don't mind a little more risk, there are incredible deals on auction sites, like EBay.

    There are genuine advantages of Sun-branded hardware over most x86 hardware. OpenBoot firmware (OS-independent configuration and diagnostics), very rugged enclosures, redundant cooling fans, clean component layout, and SCSI on the real workstations (modern low-end Sun's have IDE).

    Linux, NetBSD, and OpenBSD run on Sun hardware, too, in addition to Solaris, but Solaris will consistently provide the best hardware support, except, perhaps, for a few older peripherals (24-bit 3-slot SBus graphics, for example).

    Don't forget, what I said above also applies to other used RISC-based hardware, as SGI, HP, DEC, etc. have active secondary markets.

    The only advantage of x86 is really percieved cost, but that isn't always true. I've had much more "top quality" x86-based hardware (motherboards and modems mainly) fail than Sun-branded hardware seeing similar use. Support costs for Sun hardware really can be quite low (formal Sun support is very optional; if you don't know whether you need it, you probably don't).
