  1. Re:Here is an idea... on Data Center Standard Proposal Adds WEE To PUE · · Score: 1

    But PUE isn't that a good thing there either. It speaks to some overhead, but does not speak to how that power is sourced or how efficient it is put to use. A horribly inefficient processor that sucks down power can have really good PUE through a complex cooling system and in a region powered by coal, even if you can do the same work with a tenth of the power, but that part is not available in a design without a fan, and installed in a place where solar power provides a good chunk of the power. The more sustainable answer in that made hypothetical would be the fan cooled efficient processor getting a lot from solar, but PUE does not care about that.

    That aside, just don't screw with things. You mention caps lock, which I don't use, but any change is likely to just screw with muscle memory and not have any practical benefit except as some symbolic gesture against caps lock. For example, see second gen X1 carbon which replaced caps lock with home and end keys.

    There is also the troubling by the way mention of the right mouse button. For the love of god do not advocate screwing with the right mouse button. You don't often need it, but when you do, all the schemes that try to de-emphasize it's footprint really screw with you and again *nothing of value is gained*.

    The more troubling question is why an application should feel forced to do anything in the face of a platform upgrade in order to work at all. A modern Windows desktop can still run 10 year old software without a hiccup. Going back 20 years you start needing something like dosbox to use a lot of the applications, though still doable. I haven't tried firing it up in a while, but last time I tried the commercial package of quake 3 under linux, it still worked on a modern distribution. Same for linux neverwinter nights. As an application maintainer for some linux stuff, the only things that I can recall forcing my hand to change something for things to work were systemd and python changes.

    Android (and to a significant, but somewhat lesser extent Apple) are not doing that good with respect to application and/or hardware compatibility into the past. It's a tiring situation for developers to have to follow an upgrade treadmill in order to cater to new system sales, just to keep the current applications workable as-is.

    1. I suggest looking at Xpra. It's married to X, but is far better than X or NX at seamless remote applications. It's also an example of exactly the sort of remote experience that *could* be done within a Wayland context. The problem obviously being I had to point out something married to X as an example, rather than knowing off hand something that pulls off the same in Wayland, but the concepts are pretty sound.

    I suggest looking at xpra. X and even NX I didn't have a lot of fun with, but Xpra has treated me well. The kicker is that the Xpra strategy concept translates to an architecture like Wayland (it captures applications via compositor interface and contextual data through window manager calls).

    I have to side with those that say X's inherent network protocols are less interesting. The unfortunate fact is that everyone then cites things like SPICE and typical RDP configurations and VNC, rather than something that achieves the same seamless behavior that the fans of X want.

  10. Re:What's the point? on LibreOffice Ported To Run On Wayland · · Score: 1

    Spice is pretty crappy (after really wanting to like it for a while). I hear rumor that RDP can be decent, but thus far I've not seen examples of it doing remote application access in a seamless way.

    My personal example of how seamless remote applications can work well is Xpra. Despite it's current marriage to X, the strategy used does not use the 'remote' capabilities of X and the concept translates directly to something like Wayland. It intercepts things at the compositor layer rather than remote X calls.

  13. Re:It's not worth it any more on Intel's Tick-Tock Cycle Skips a Beat · · Score: 1

    Intel has had a process lead, but that's not the only reason they make abnormal margins.

    - Lock in. AMD's the only viable x86 vendor and they've been off in the weeds after their glory days that culminated in x86-64 and NUMA x86 architecture
    -Ecosystem. Intel invests heavily in things like compilers and standard libraries and so forth. They pay to have good software developers enrich an ecosystem that favors their processors
    -Microarchitecture. They frankly have very good hardware engineers.

    ARM came to prevail because Intel took their eye off the ball in the low power space. Recent Atom family designs have made a strong showing in that space (in part due to software developers creating remarkable ARM emulation, in part due to excellent hardware design, and in part due to the business call to compete at more typical (for the market) margin). The 'ARMs sip power' reality was (unreasonably) extrapolated to "they'd kick ass in the datacenter", but now studies are being done and the ARM server designs are losing both on raw performance and performance per watt to the Intel offering (e.g. one done by CERN did open power 8 v. aarch64 v. two x86 variants (atom and xeon e3) and the x86 variants won most everything (except POWER did SMT better than most, but even that fell apart most of the time).

    While this looks like a perfectly reasonable language, I'm a bit weary of this sort of bragging about line counts. I could do the same thing, it would look roughly like:

    (abs and get_temp are up to the person to have the functions).

    Talk about the syntax being nicer, but lines of code is no big deal in this particular case. It has a nice and non-ugly 'run this on another host' syntax and automatically takes care of the communication channels in a reasonable fashion with a low amount of fuss. Leave it at that.

    I think across the industry the latter is at least somewhat more common (it's the simplest explanation for the high volume of H1-B requests from specific companies, it's unlikely one company would need the former case by the hundreds).

    It's also a field with a lot of solid technical high level algorithms, so there was a pretty good space to map things to. Basically it was identifying what inscrutable code was doing as it relates to well known algorithms, enabling them to start fresh to apply the best practice today of said algorithm. If you are not in this sort of space, the strategy doesn't really have a way to help very much.

'The Cloud' work is important, but more than important, the people doing it are *louder* than everyone else and the media coverage high since it is novel, but mainstream is remarkably little changed over the last several years.

    RTM did mean that all the showstopper bugs were taken care of, and the concept of "ship it, we'll patch it later" just didn't work. All I do know is this -- Microsoft is toast if Grandma can't upgrade her Windows 7 box she bought at Best Buy with zero issues.

    That is the facet I find concerning, 'RTM is no big deal' statement is bad because it *should* be a big deal.

    Maybe they can juggle LTS and non-LTS effectively, but they have every risk of getting too caught up in the enthusiast perspective and pissing off a lot of their users.

    This means if an attacker is able to intercept your SMTP, they could still hijack your account through requesting a password reset at will, so it's not perfect, and yes some 2 factor authentication would be nice *if* it were an important site. Account creation needn't have this particular hole, just password reset.

    If you didn't want to SMS, you could use TOTP (e.g. google authenticator is one implementation, but not the only one). Though either way that's something to potentially lose so it would be a suggestion option for those increasing security.
