PCMag's PCTech Reviews Linux Kernel 2.2

Gryphon writes "PC Magazine has published a pretty level-headed 8-page review of the Linux 2.2 kernel. Mostly a features review, compared to Windows NT. I think this is pretty significant, considering a lot of Windows users (including me in years now past) read that magazine! "

  1. No PnP support?? and other things.. by Anonymous Coward · · Score: 2

    Please wake me up, I must be dreaming that my PnP sound and network cards configure themselves...

    [ On filesystems: The reason it was stressed, I suspect, is simply that Linux supports more. Lots more. Lots, lots more. NT supports, what, FAT16 and NTFS? I believe I found a Win95 program to read ext2 partitions but that hardly qualifies as 'support' -- in particular, I can't mount them as proper filesystems. A quick scan of my kernel config shows 13 possible foreign filesystems, if I compress all the offerings from Microsoft into one entry. And I'm not even counting the network filesystems. AFAIK NT only supports NCP and SMB natively. If you want to include 3rd party drivers you should also include all the 3rd party kernel drivers floating around, which include a number of versioning and journaling filesystems...I think at least one of them compiles ;-) ]

    AFAIK the Linux API does not change for 64-bit processors (correct me if I'm wrong); I consider it to be a sad comment that Microsoft even has to publish new interface specifications. (I guess hardcoding variable sizes into their type names caught up with them?) Most well-written code should just need a recompile. (now that I've said that, I'm sure that all my code will fail on a 64-bit arch :-P )
    I'm rather confused about the occasional assertions that NT is more stable than Linux. 'as stable' I can see. But the only time I had to reboot Linux lately was when the filesystem code freaked because of physical damage to a floppy. (I think this is inexcusable personally, just so you know :-) ) I've rebooted it other times, mainly to play with the Hurd, but unless I'm playing with things marked "do not install unless you really really want to risk your stability" it..just..never..dies.

    Just a sidenote: Neil Randall isn't exactly new to Linux.. He published a very nice piece in the July 1997 issue of PC Magazine called "Leaning Toward Linux", in which he acquainted the reader with the Linux kernel in general (development model, history, etc.) and with each of the major distributions. He also provided a detailed walkthrough of installing slackware, and some tidbits on the X window system.

    An article like that might not seem like much today, 2 years later, but back then that was great press coverage. It's nice to see he's still on the Linux bandwagon.

  4. A few mistakes by John+Campbell · · Score: 2

    Not bad... I only caught a few technical inaccuracies.

    NTFS support is read only.

    2.2 includes an experimental read/write NTFS driver.

    DSL and cable modems are mostly unsupported.

    Every DSL or cable modem I've ever seen has been an Ethernet device, and Linux works fine with them. If they're talking about phone/cable company support for Linux, that may be another story, but that's a PHB issue, not a technical problem.

    They state that SMB is a networking protocol, like IPX, rather than a network filesystem, like NFS.

    They missed a couple of ports and a couple of filesystems, but, hell, I can never remember all of them, either...

    And they didn't include Slackware in the list of distributions.

    I personally have Linux running on four different 386es.

    There's eddi, a 386SX-25 with 4M of RAM and an 80M disk, which is my laptop. Not a blazing fast machine, but she was cheap ($20), she's portable, and she's sufficient for carrying work around with me. You don't need a lot of space or processing power for writing code, or even for compiling small projects. She's currently running 1.2.13, because she hasn't got enough disk space to compile a 2.0 kernel.

    There's deliah, a 386SX-16 with 8M of RAM and no disk. She boots a 2.2.5 kernel off a floppy disk, then configures her ethernet and mounts her filesystem using BOOTP and NFS. I use her as a not-entirely-dumb-but-not-very-smart terminal for my faster machines.

    There's gabrielle, a 386DX-40 with 20M of RAM, a 120M disk, and a 1.0G disk. She runs X, and I use her as an X terminal. Mostly I run stuff on other machines with the display redirected, because she hasn't got enough horsepower to handle X and, say, Netscape at the same time. I also use her as my guinea-pig machine. Because she doesn't do anything mission critical, I use her as a test bed for new kernels, new libc installs, and such things. If I screw her up, no big deal... I could wipe the system and reinstall it without losing anything important (I haven't had to do so much as a floppy-rescue yet... which is fortunate; gabi's got no floppy drives). She's currently running 2.3.5, and if I get sufficently bored today, I may download 2.3.6pre1 and compile it. Sure, it takes four hours, but there's no reason I have to sit around and wait for it.

    The last one is leviathan, a 386SX-25 with 8M of RAM and a 120M disk that I'm planning on embedding in my dashboard as a CD player and radio as soon as I get the power supply for it built. It's currently up and running in a caseless heap on my card table.

    I'm not even going to get started on the 486es I'm running Linux on...

    these things right for once:

    1. Comparing Linux kernel features to NT kernel
    features instead of doing another "Linux/Apache

    2. Pointing out that the Linux installation
    process depends on the distribution you use,

    for newbies in each installer is disk partioning
    and the video card and monitor settings for X.

    as IP multicast and frame buffers console are
    important.

    4. Pointing out the areas where NT will be playing
    catch-up with Linux such as supporting Merced.

  9. It's full of mistakes by red_dragon · · Score: 2

    The non-technical nature of the article seems to be due to the author's unfamiliarity with the subject. There are many lines that are either pseudo-typos or flat-out misunderstandings. A few examples:

    • SGI 'Virtual' Workstation
    • "TV tuner cards and video capture cards are enhanced through a new driver (BTTV), which, among other things, lets the card write directly to memory, bypassing the CPU, to produce a higher-quality image."
    • "...but you can now change the kernel's configuration through Linux's virtual file system instead of rebuilding and recompiling."
    • It says Linux has two native filesystems, but 2.2.x doesn't have extfs anymore.

  10. Well, I dunno by manitee · · Score: 2

    It seems to me that the average Joe computeruser, even the ones who are really into gaming or whatever, either has not heard the word linux or has no idea what it is. Sure, articles like this one help, as it appeared in a widely-read Windowsesque magazine. But to most, linux is still freak show material.

    Some recent improvements have made things better. Though the actual distribution (IMHO) is about as stable as a drunk prom date, the Red Hat 6 installation process was fairly painless (I have always and still do run slack). Personally, I dont care about installation proceedures, but to sway sheep to the flock, it's got to be idiot proof.

    Idiot being the key word.

    Positive things are happening. I think that with time, the product will improve and 'sell' itself. We simply must be patient, and continue to hone linux into an even more robust and powerful OS.

    It's disappointing to see the current proven functionality of Linux 2.2 compared against Windows 2000 in this article. I'm sure many admins are deciding whether to upgrade to Win2K or to Linux, and they would like to see this sort of comparison. But if we're going to compare a product which has been released and thoroughly used for months with a product which may not be available for months (unless you're a beta site) then we might as well compare against a future Linux release as well.

    PCmag would have done better to compare the current Linux 2.2 kernel with the current NT4 release and Service Packs available in stores for the bulk of the article. Then at the end they could state that Win2K promises these additional features, and Linux 2.4 will have this other list of additional features over 2.2. That would be a little more honest of a comparison.

Nobody would ever take it seriously as an unbiased comparison.

    To everyone in here that is ripping the minor points of this article, calm down!

    In comparison to past articles, this one shines as being quite fair. Remember that PC Mag might as well as been MS Mag a year ago. I don't think a Linux magazine would have been so friendly to Windows 2000. Further, PC Mag was NEVER as friendly to OS/2 as this article is to Linux.

    I think it is OK to compare Linux 2.2 to Windows 2000. NT4 has been around for a while and most people looking to put a server into place over the next few months will be looking at Windows 2000 and Linux 2.2. 2.4 is very far away and should be not be considered.

    It didn't bother me that the auther switched around between Windows versions. The article is not about which is a better server, etc. but just a general feature comparison. If you are in the Windows world, you get this, in the Linux world you get this. Most admins are not concerned about getting PnP on servers, but are very concerned about getting it on workstations.

    The author did refer to features that are not available yet, but will be in Windows2000, but he did the same for Linux. For example, he said that IP tunneling on Linux only does IP, but also said that other protocols will not be far behind.

    The author also didn't say Linux was lacking a feature simply because there wasn't a button to activate the feature. Never have I seen the flexibility of the sysctl stuff in /proc discussed in an article. This guy did even though there wasn't a point and click interface.

    He even pointed out that even though Windows may be more user friendly, Linux users love the control they have with Linux!

    In future, please calm down and treat an article that is decent as it should be treated. Just because it is in PC Mag doesn't mean it should be ripped to shreds. Otherwise, the media sees the Linux community as a bunch of religious zealots and not the serious group of users that just want a good OS that we are.
