Slashback: HAMnation, Books, Criticism

An update on the health of troubled HAM satellite Oscar 40; a bit more on free online books -- but this time all good news; a nice in-depth report on the state of Mandrake's latest offering; and an earth-shattering change to the previously reported report from the Real-Time Linux Workshop. That (and absolutely no expression -- none whatsoever -- of wishes for you to experience a pleasant millenium turn) is what you'll find below in tonight's Slashback.

Reversing the dilithium crystals is not an option in this case. $FFh writes: "AMSAT-DL President (and P3D Project leader) Dr. Karl Meinzer, DJ4ZC, provided ANS with additional information regarding AO-40's recent S-band transmissions on 2401.305 MHz:

Ian, ZL1AOX, has succeeded in loading IPS software and a minimal operational package into AO-40. As a consequence, AO-40 is now sending telemetry (A blocks) that will enable an analysis of the status of the spacecraft.

A first (quick) look has revealed that some temperature sensors and possibly some current sensors have been lost by whatever incident caused the telemetry transmissions to stop. However, the power situation, in particular the battery voltages, look nominal.

We will now start a detailed analysis of the situation; the command stations will continue to follow a conservative philosophy with the primary target of not causing any additional damage along with retaining as much evidence as possible for the analysis of the incident.

Furthermore, command stations will now try to uplink the entire operational software package, which in particular should establish positive control over the power generation system. From there on, the communications capabilities of the spacecraft will be explored. The 2-meter transmitter is considered off limits for the time being (in case that it may have been damaged and thus might have the potential to cause the IHU to crash). The risk is too large before the Warte-Orbits and Command-Assist programs have been updated to reflect the actual capabilities of the satellite available after the incident.

In summary, we can state that the command stations have now regained control over AO-40. During the next few days we hope to learn to what extent the satellite was damaged and to what extent this will impact mission targets."

Read up -- then spread some praise or some griping! bcrowell writes: "The Assayer is a web site for user-contributed book reviews, with a focus on free books. All reviews are free information. We now have 35 free books on computer science in our database, almost all without reviews. A common argument against free books is that without a publisher, there's no way to filter out the junk -- if you'd like to prove otherwise, it's time to do some reading!"

Dissecting Mandrake 7.2: Beyond Eye Candy Linux Tests writes: "Linux Tests published their first review of a distribution. Linux-Mandrake 7.2 was chosen as the first victim -- umm -- first distribution. Linux Tests did the installation several different ways over several weeks timeframe in order to answer the age old question, "Is this right for someone new to Linux?" Find out if this distribution answers the question well."

Their review reflects my experience with Mandrake 7.2, as well -- some glitches, a lot of slickness, and some problems with the manual vs. reality. (On the other hand, Mandrake remains one of only two distributions I would recommend to parents and siblings at present.)

The Linux Tests' site looks like a great resource, too -- three guys grousing is a cool basis for a web site! It will be nice when hardware manufacturers realize that a perhaps small but significant fraction of their buying audience is paying a lot more attention to their products then they may be used to. Publishing specs is always nice, eh?

Now kiss, make up, and have fun, ok? DaGoodBoy writes: "John Roderick, the Director of Rosen Interactive, contacted us with a rebuttal to some of the statements our member Kenneth J. Hendrickson in his recent "Report on the 2nd Real-Time Linux Workshop" which ran here on Slashdot. Details are available here"

    There is absolutely NO excuse for requiring a re-install of the operationg system when hardware changes. In my opinion, that is a serious liability. What happens if you have a motherboard failure (stuff like that happens), and the motherboard is discontinued, or now ships with another bios or is a newer revision. I agree totally that motherboards are not all the same (I'm not that naive--I've designed microprocessor-based systems and written BIOS routines, etc. I know that there can be significant, important differences in motherboards, even if they are the exact same models but different revisions--this is reality even in much simpler systems like I worked on). Also, What if you want to make several "Images" of a drive to ease installation of W2K Pro, but can't count on all the PC's to be IDENTICAL?

    Obviously, for mission-critical stuff, you would have a backup server in the event of hardware failure, but you still need to restore the primary machine. Instead of puking out a STOP 0x7b when it encounters a certain driver/hardware mismatch (as has often happened since NT 3.51) why can't Win2k catch the exception and continue with the "generic" drivers, and allow the user to correct the problem without an invasive repair/re-install process? THERE IS NO GOOD REASON why it can't. Microsoft already allows you to boot in "VGA Mode" if you change video cards. This could be extended to all subsystems.

    Yes, there ARE countless different motherboards. However, all decent ones have the same entry points into the black box. They all have PCI and AGP slots, they all support the same BIOS calls and so on. Why can't Win2K (even if only in "Safe Mode") deal with the common denominator in the event the "optimised" configuration no longer applies. I know it seems harsh to hold Win2K to those standards. However, if I'm a company paying tens of thousands a year in licensing fees, a "smarter boot sequence" to save many hours of IT work isn't just a "nice" thing. If the FREE competition appears to be superior in that respect it would be something I'd DEMAND in return for those thousands I gave to Microsoft--particularly then they won't even give me the tools (ie. source code) to make improvements myself (improvements I'd be willing to share).

    Yes, I do have a double standard w.r.t. Win2k vs. Linux. It's because they are two different situations. Linux isn't "perfect" or "optimised for everything". However, it is free (monetarily) so you get more than you pay for. It is also Free (open source) so I can contribute improvements. Until MS Windows is Free (open source if not monitarily) I will not be nearly as forgiving with it's shortcomings.

It's great if a user can install the system easily, to be sure. But once that slick installation is done with, you've got a user left staring at an XDM login screen or a console login, thinking, "Okay, what next? How do I get into linux? What do I do?"

    System installation is simply a means to an end (the means - installing an OS. the end - an installed OS). Why do we need fancy X-based gui installers that let you play tetris while the packages are installing? The goal of an installation tool is to get the packages on the system, and get the system setup in more-or-less working order. Too much effort has been wasted by the likes of Redhat, Mandrake, Corel, Caldera, and even SuSE (though YaST1 is still an excellent installer and system management tool) developing ever slicker installation routines, while that effort could've been put to use somewhere important, like writing better documentation, or increasing usability of system management tools (linuxconf is a joke), or other more-worthwhile endeavors.

    How often does a typical Linux user install any Linux distribution? Aside from the newbie who probably should reinstall every other week or so (knowing you'll be reinstalling eventually is a good way to clear your conscience about "breaking" the system while learning), the loonies that need the latest and greatest Redhat, and reviewers who focus all too much on installation, for most of us installation is a one-shot deal. We install the system, tweak it, and then let it run for who knows how long.

    It simply boggles the mind, seeing developers spend so much effort on something that is such a small percentage of the overall user experience, and then seeing users encourage such behavior. Installation needs to be "Good Enough", meaning it's fairly easy to comprehend (a good manual and help system goes a long way, here) and doesn't screw up your system.

Start from the current unstable, then use apt-get like you'd use rpmfind, installing the new version of a package when you find that the old version doesn't cut it.

    Shielding is often ineffective because if you hit shielding with a high-energy particle the result is a bunch of low-energy particles that are even worse as far as memory and logic cells are concerned. The preferred shielding material is tantalum which is expensive and very difficult to machine, and adds mass to be lofted to orbit. Static rather than dynamic logic is more rad-hard and uses less power, so the StrongARM is a very good choice for a satellite.

    Thanks

  34. Assayer Important for Open Content by phinance · · Score: 2
    The Assayer helps defeat one of the arguments against open content -- that editors/publishers are required to protect readers at large from having to wade through junk. That puts a lot of power in the hands of few. This open reviewing system lets "the people" decide for themselves.

    With the big-publisher filter out of the way, we should hope to see more niche or small-market content (or content that might not be appreciated by big publishers) become available.

  35. Mandrake 7.2 Apache RPMs by Vulcana · · Score: 2
    In the article they say
    We purchased the Linux-Mandrake 7.2 Complete version from a computer store.

    Does anyone know if that is a difference between the downloadable ISO images and the "Complete" version?

    Using the downloadable ISO and an expert install I installed Apache straight from the initial setup. I also noticed that the apache rpms are available under Mandrake/RPMS on the install CD (not the supplimental CD)

  36. Its a bit of a chicken and egg situation by Flabdabb+Hubbard · · Score: 2
    So long as the user actually has to install the operating system by him or herself, it will be a problem for the less tech-savvy.

    Linux is almost as easy to install as windows98, given someone with a reasonable level of technical knowledge, however many PC users are simply not that technical.

    Whilst they may benefit from Linux and all its plethora of free (as in beer and speech) software, they still cannot be expected to install it themselves.

    Its a chicken and egg situation, people use windows because its what came with their PC

  37. Use != Install/Configure by dbirchall · · Score: 5

    If Linux is going to compete against MS on the desktop market, it needs to be easier to install/configure. Once Linux is installed and configured, it tends to be at least as easy to use as anything else out there, if not easier, simply because it doesn't go belly-up and demand to be reinstalled, used in safe mode, or whatever. A machine with Linux properly pre-loaded by the OEM is no doubt a joy to behold.
