    1964 + 25 + 25 = 2014 new bump?

    Maybe this is just the half-time of the shots, and it's time to refresh? I.e. "2014, third dose recommended"

    20TB is not out of the world. With a RAID of 4TB disks you can cover that at home, and it doesn't need to be on all the time. Maybe you can reduce the amount of disk usage by reducing duplicate content using bup or an appropriate FS.

    SN1a are only one of the tools astronomers use: https://en.wikipedia.org/wiki/...
    The small distance measures have to match with the medium ones and those again with the largest distance measuring tools. Also on the same level, they should agree.

    The benefit of SN1a is that they are abundant, and their method seems to have particularly small systematic uncertainties. Other methods for computing distances are for instance Baryonic acoustic oscillations, which also provide a scale.

  6. Re:Yes they did. on Ask Slashdot: Does Your Employer Perform HTTPS MITM Attacks On Employees? · · Score: 2

    In the US, this is totally legal, although there may be disclosure requirements (I'm not sure). The "my system, my rules" argument wins. My workplace does this, and they informed me that they do this when I was hired.

    That's ridiculous, there must be some limits. The argument "my system, my rules" will not work if you were to whip your employees like slaves, so why should it hold for taking away other rights? Signing them away is a nice try, but you can't sign away all your rights.

  7. Re:Misleading Summary; Less than exhaustive resear on Low-Protein Diet May Extend Lifespan · · Score: 3, Insightful

    Any reasonable recommendations can only come from large, longitudinal studies, over multiple generations. You know, those that shape the food pyramid / WHO guidelines. And they do exist, and give pretty clear ideas. Such as that halving your meat intake is a good idea.

    But I guess that's not exciting, news needs to either repackage (MyPlate) or go after highly fluctuating results from microstudies which is the latest research, but in the stage of formation (all these diet fads, X is bad for you, Y heals cancer, drink a glass of red wine a day [because a encyme in a petri dish did something], etc. ).

    By the way, why does there need to be one right way of nutrition? Why can't we accept that multiple ways to obtain the basic building blocks are possible.
    In the end, we can't be so off by so much: We have so many people living with such a big variety of foods, and they are doing pretty similarly well (i.e. get older than, and are healthy at, 65). The need to prove that everyones diet is completely wrong is ridiculous.

  8. Re:Permenant Beta on Google Won't Enable Chrome Video Acceleration Because of Linux GPU Bugs · · Score: 1

    Typically, Linux applications work around bugs with various tricks and (mis)use of X calls (see Ilja van Sprundels talk on 30c3).

    Perhaps a standardized test suite program that systematically tests all 3D features in order, in combination -- similar to the Acid Browser tests -- would help evaluate which GPUs are well supported in Linux/X. You know, trying to actively crash X in the most distinct ways possible.
    Then people would be more pressured to make their drivers work properly, rather than saying "well, youtube seems to work, so I guess it's fine".

    Adding some randomness will probably go a long way discovering bugs (with some seed of course, to make the bugs reproducible).

  9. Re:All thanks to OpenBSD, eh? on Yes, You Too Can Be an Evil Network Overlord With OpenBSD · · Score: 1

    Yes, all you need is tcpdump, punchcards and butterflies.

    What do you use then to limit the bandwidth to/from certain sources, and monitor the bandwidth of certain types of traffic, e.g. on Linux? A port of this would be useful. In my usage scenario, a few hundred users share a upstream network, and the traffic from a few (youtube, streams) can dominate the others, making web pages slow for the others. A fair distribution would be nice, but when fewer users are online, the full bandwidth should be available.

    I only know iptables, which is too low-level and static, and you can't give it into users/administrators hand (so many things can go wrong). For analysis I use ntop so far (which does hang sometimes, requiring restarts). A really interactive tool for traffic shaping would be needed.

    pflow/nsfen seems to be the right thing for BSD. Is there something good for Linux?

  12. Re:Short Evaluation on Ask Slashdot: E-ink Reader For Academic Papers? · · Score: 5, Interesting

    I wrote a small script that takes research papers and splits them up if they have two columns. It tries to figure out when you have figures, and to strip away the header/footer etc. It produces epubs (which you can convert with Calibre)

          https://github.com/JohannesBuc...

    The pages are first converted to images, the white spaces figured out, and the page sliced and diced. The linearized content is a sequence of page number, and rectangle definitions. You could make those into a pdf again, but I just stick to images and html (epub).

  13. Re:I'm sorry I'm an idiot on Gnome 3.12 Delayed To Sync With Wayland Release · · Score: 5, Interesting

    In my opinion...
    Wayland + Systemd + Gnome 3 + kernelspace Dbus = transforming Linux into Windows. Or something more like Windows. They represent a complete rejection of the foundational Unix philosophy.

    Regarding Wayland: You clearly have no idea how X works today. Todays X is not like Unix should be at all.
    Regarding Dbus: How is a dbus protocol different from semaphores and shm in the kernel?
    Regarding systemd, I agree and see it critically, because it is tries to solve everything at the same time. Perhaps the direction of OpenRC is more appropriate. But to criticise systemd you have to understand the issues: A number of links are on http://freedesktop.org/wiki/So... including http://0pointer.de/blog/projec...
    Regarding Gnome3: Gnome3 is conceptionally little different than Gnome2, KDE or XFCE: Windows and pointers. I actually really like it. If you don't exchange it for something else. Very Unixy.

    We have to keep in mind that the system we have today are not mainframes that are booted once and have their daemons running for months.
    We have plug-and-play of devices and screens, hibernation, multiple input devices, while at the same time the screen output must not flicker or have delays beyond 50ms. It's a different arena today.
