    Has the 2.6 branch been patched with exec-shield yet? I know there is some compatibility issues, but Linus said he was going to allow it anyway.

    I'm repeating this message from OSNews, which had the story first.

    I think Linux is a great kernel, but a 42 MB download is really a bit too much for my liking. Much of that is code for hardware that I don't have or features that I don't want. I am a great advocate of modularity, and I would like to see it applied not only to the compiled kernel, but also to the sources. I am aware that this will add some administrative overhead, but it could save a lot of traffic and CPU time.

    Here are some ideas:

    - Split the distribution in a base that has the common stuff, and optional add-ons for lesser-used network devices, filesystems, etc. etc.

    - Employ a BSD ports like system that downloads the sources on request (i.e. when compilation of some part is requested)

    - Distribute only the configuration interface, and download only the parts actually needed based on the configuration selected.

    I am too occupied now to come up with a proper proposal, but I hope this will set some people thinking.

      That would probably ultimately result in the definition of a stable module interface between the linux kernel and device drivers. This has been explicitly stated as a non-goal by Linus for his tree as it would facilitate the production of closed-source hardware drivers, and we/he wants to "encourage" open-source device drivers (quite rightly IMHO, but I disagree with his method*).

      * I think a stable module interface might be _good_ for open-source drivers - hardware manufacturers may never produce their own open-source drivers, but if they are writing closed source drivers to a stable API, that stable API becomes a breakout point at which reverse engineers can install analysis and produce the information required to produce a community-written open source driver. But the trouble with that is that the United Reich of American Corporations has begun pushing for criminalistion of reverse engineering.

      Here's an idea, download the patch instead and apply it to your 2.6.7 kernel source.

      I wonder if the gentoo maintainers have any plans to offer such a feature.

      Gentoo frequently downloads just a patch for security fixes - which is really nice if you have a modem, and you still have the original source lying around (gentoo caches source files, and will re-download whatever it needs).

      However, the routine isn't smart enough (to my knowledge) to determine what you already have and as a result what you need to download.

      So, if you're running 2.6.7-r6 and -r7 comes out, it is reasonably likely to download a patch.

      On the other hand, if 2.6.8 comes out it probably won't. If you go strait to 2.6.8-r1 it will probably download all of 2.6.8 and a patch to make it -r1.

      Actually, no - it's not that they want to discourage closed-source drivers, it's just that they don't want to be prisoner of this "stable api" for the sake of some closed drivers.

      They basically want to have the freedom to evolve the api as they see fit - and sometimes there's good reasons for changing it. If a stable API means being stuck with the design decisions which maybe made sense ten years ago but not anymore, I'd rather have an "unstable" API.

      So basically, if you want to provide closed drivers - feel free, but don't come crying if the API changes. But it's not like Linus' does this to deliberately sabotage closed source driver providers.

      As an aside, it's the same for people who provide open source drivers living that aren't merged with the Linux tree - they'd probably like a stable api too. In that sense they're just as screwed over or "discouraged" as the closed drivers. If they're merged, someone would probably make sure they're fixed up.

      But, if a stable API gives people the excuse to not have to maintain their drivers, then maybe we're better off without. Like when hw manufacturers decide it's not profitable to support their previous generation hardware.

    I guess they were really serious when they said that the stabilization of the kernel was up to the distro maintainers. Guess I won't be downloading 2.6.8 until 2.6.9 comes out.

    They've been saying for some time that they'd also release small updates (like 2.6.8.1) against previous releases when necessary, so it should be reasonably safe to take a recent kernel if you wait a couple weeks after the major release and check for any such updates.

    For what it's worth, I've been upgrading on every major release (and most of the -rc's too) since 2.6.0, without any disasters.

    Of course, depending on which particular drivers you care about and so on, your mileage may vary.

    Hope your friends are ok! It's now too late in the day, my shortwave reception has dropped off. I saw some pics uploaded last night from another forum that showed some nasty destruction in I think port charlotte, someone still had net connection some how. Whole buildings smashed, etc.

    I've been through at least three I can remember the names of, agnes, frederick and opal. Agnes I though we were goners, we were supposed to evac, but all we had were bicycles so we stayed put and buttoned it down, little duplex on the beach I had with two girls, hmm, this was 72. It flooded the block and tore a lot of shingles off, etc. the next day we wandered around looking at what we called sea monsters, all kinza huge fish washed ashore and stranded. It was quite the mess. That whole neighborhood is gone now, it's all very expensive beachfront high rise hotels, etc. That was at madeira beach florida. Agnes hit much further north, we only got the sideways edge of it and it was one spooky night, tell ya what. Frederick I was living in my VW camper at the time, I stayed down at the beach as long as I could to enjoy it,sto9rms are pretty nifty if you like that sort of thing, then went inland to some campground and parked it in the middle of a field away from any trees with the windshield pointed towards the storm front. Pretty high winds but I don't think they went past 70 mph or so, so it was like driving on the freeway but sitting still except for some rocking. That was outside tampa as well. Hurricane Opal I was up in atlanta, it churned it's way a;; the way up there and knocked down thousands of trees all over, lady up the street from me had a huge tree squish her real pretty old 60's barracuda. My landlady at the time evacced to her basement, a big tree fell, penetrated her roof and drove a tree branch right through her bed where she would have been sleeping. Man, I got a lot of free woodchips and firewood after that storm, the powerline guys were begging for places to put the stuff, so I filled my driveway with it, then used it landscaping, etc. What a mess that storm was.

    I've also been through some dandy blizzards and floods and forest fires and tornadoes, which got ot be the worst I think because the destruction is so total. Seen most of the usual natural disasters except for a big earthquake, and I'll pass on that.

  6. Rsync? by msh104 · · Score: 2, Interesting

    the kernel seems to have a rsync mirror. I haven't tried it yet, but that way you would be able to download the kernel in cvs style by only downloading what you need. this ofcourse only has a adventage when you download new kernel versions all the time, but most people that download from kernel.org seem to do just that. I also like the all in one package. this way I don't have bother 'bout searching for supported hardware. if it ain't in linus tree, it's not worth it for me.

      Nice idea, but I haven't yet seen a kernel mirror which carries the source in plain .tar format. It's always .tar.gz and .tar.bz2.

      A specific rsync mirror which carried it as just .tar would allow what you say to work, and it should work very well. Very little management overhead to set up too (particularly compared with trying to make the source tree modular).

  9. Spinning down laptop drive hardly helps by timeOday · · Score: 2, Interesting
    I wonder if your laptop_mode experience is like mine - it hardly makes any difference at all? I already had cpufreq going to control cpu speed, and get good battery life from my T40. But using laptop_mode to let the disk drive spin down makes hardly any difference - at most 10 minutes on top of the normal 4 hours or so. (And I was monitoring the drive with "hdparm -C /dev/hda" to make sure it the drive really was suspended.)

    Adjusting the screen brightness makes a slightly larger difference, but not much (maybe 20 minutes between second brightest and most dim).

    What really makes the difference is CPU load. If I run a lot of cpu-intensive stuff, and let the system adaptively raise the cpu frequency to handle it, it can cut battery life by more than half! Luckly I can comfortably play movies and do word processing with the CPU locked at the slowest speed (600Mhz), but to do much development work at the same time it really helps to let the cpu ramp up.
