    sad news for you, w3techs found that RedHat became #2 in server space in mid 2012.

    Complete bullshit. You're massively misrepresenting the story.

    The survey was only web servers, and those certainly aren't the majority of all servers. The numbers say nothing about the server space at large.

    And RedHat was never #1... Instead, #1 in their ranking was previously CentOS.

    Even then, RedHat distros are only behind because they've split their numbers between CentOS, RHEL, and Fedora. Combine those three (or even just 2), and they're still easily #1.

    You can't complain about anyone "blatantly ripping off RHEL". most of the distro is NOT producted by Redhat but 3rd party projects (linux kernel, fsf compiler and tools, apache project etc.) do the heavy lifting of making any Linux distro while redhat profits from their work.

    No, that's what Debian does, but it's absolutely NOT what RedHat does. RedHat pays numerous open source developers. They're major contributors to many popular open source projects, like the Linux kernel, GNOME, and many others.

    whether it's most vendor-supported depends on what you want to run.

    No. "Most vendor-supported" means exactly that. You might find some areas where it's not as pervasive, but that won't change the facts.

    I want to run servers.

    Which Linux distros are supported on Dell PowerEdge servers?
    RHEL and SuSE.

    Which Linux distros are supported on HP Proliant servers?
    RHEL/CentOS/OEL and SuSE.

    Which distros are supported for Oracle 11i?
            Oracle Enterprise Linux
            Red Hat Enterprise Linux
            SUSE Linux Enterprise Server

    What versions of Linux are supported by EnterpriseDB (commercial version of PostgreSQL)?
    RHEL/CentOS and SLES across the board. *some* small number of versions are supported on Ubuntu. (No Debian support).

    It's utterly insane to claim RHEL isn't the most well supported distro out there. It overwhelmingly is.

    so many other distros have such superior and polished desktops.

    Actually, I find RHEL to be the best out there. It's quite reliable, and they've included the full compliment of apps you might need, without duplication or lots of stuff that half-works and breaks periodically. My only complaint about GNOME on RHEL6 is that it defaults to the Mac-style top taskbar, instead of the old GNOME 0.x style that Windows 7 adopted.

    I haven't seen a RedHat enterprise desktop in a decade. and that's a good thing.

    RHEL is #1 in the enterprise, and it's an easy choice that if they're willing to use Linux on workstations, that those are going to be RHEL, too.

    I've personally rolled out thousands of RHEL desktops for companies over the past decade, so I'm sure they're doing just fine.

    And other distros, not redhat, allow access to their repositories by anyone since paying customer pay for *support* and having public access to repos is way of advertising, marketing and getting community goodwill

    You can complain to Oracle. They're just blatantly ripping off RHEL, and offering to take over support of any existing RHEL installations, directly threatening Redhat's only revenue stream, and throwing into question the very viability of the Open Source Software business model.

    Redhat is the most vendor-supported and most profitable version of Linux, so they're the first targeted, and the first to run into problems like this. But it's safe to assume other distros will eventually have the same issues, and switch to similarly restrictive models. As long as CentOS is out there, I'm not concerned about going down the RHEL path.

    It's also more difficult to line up regular work, and more hassle. Various opportunities might overlap each other. Signing-up with a new company, and feeling-out your new environment, boss and co-workers is always a tine-consuming process, and one I would prefer not to do frequently.

    And don't forget that a big chunk of that contract salary is going to be eaten up by taxes your employer isn't paying (see IRS form 1099), medical insurance you'll have to pay for, vacation days you won't be paid for, and more. People get excited when they see the big number on paper, and don't realize how much smaller the real number is.

    Contract work is great if you want lots of unpaid time off, but remember that it might not be when you want it. I've found salaried positions pay much better, on average, than contract work.

    The writing was on the wall for a long time. After they bought Compaq (which previously bought DEC), HP got a ridiculous number of proprietary OSes and server architectures under its umbrella, and they had no sane approach to manage them. On day #1 they should have announced that they were going to merge all the major features from Tru64 (Digital Unix) and HP-UX together into a single product. They should have done the same thing with OpenVMS and their NonStop OS. That would have joined some of the fractured camps together, instead of keeping them fighting each other. They only even attempted to (slowly) unify their products in processor architecture, and they made the monumentally brain-damaged decision to throw all their eggs in Intel's Itanium basket... Killing Alpha, PA-RISC, and others, giving us the x86 hegemony we have today.

    HP will stay in the x86 server business for certain, since they're number one ahead of Dell, IBM, NEC, etc... Even though they're really selling Compaq Proliant servers, rather than HP's own old server brand.

    They've been too large for too long, and their leadership has been ridiculously risk-averse, and resisted any sane decisions in paring things down before they started absolutely hemorrhaging cash because of these stupid decisions.

  8. Re:FLAC superiority to MP3 on FLAC Gets First Update In 6 Years · · Score: 0

    MP3 compresses audio files so that they have the same playback within the range of human auditory sensation.

    Really? Those 32kbps MP3s sound perfect to you, do they? Those 128kbps MP3s that have been re-encoded over and over again sound perfect to you?

    In fact, MP3 and most other lossy codecs can't do artifact-free audio encoding at any bitrate. They work in the frequency domain, giving them very poor time resolution, so they badly screw up quick impulses, particularly things like percussion, applause, etc. Most common codecs fall into this category... MP3, AAC, HE-AAC (v1/2), Vorbis, Opus, etc.

    If you really want something a person can't differentiate from the original at a low bitrate, you have to resort to temporal domain codecs. These include Musepack, MP2 (MPEG-1 Layer2), DTS, the old high-bitrate ATRACv2, etc.

    https://en.wikipedia.org/wiki/MPEG-1#Quality

    This will be of the utmost importance if you are a dog.

    Dogs can hear higher frequencies than humans, but MP3 and FLAC have nothing specific to do with sampling frequencies. You can encode 44.1KHz or 96KHz into FLAC or MP3 if you are determined to do so.

    Psycoacoustics are modeled on normal human auditory systems, so non-humans would probably hear a few more artifacts from MP3 encoding than humans, but that's about it. That also applies to humans with compromised hearing... Certainly, things like intensity stereo won't fool something with only one ear into thinking it sounds anything like the original, though that's not to say it'll necessarily sound very bad.

    I have not checked lately, but it used to be the case that a lot of things broke if you changed the root shell.

    I don't believe you've checked... EVER. There's nothing TO break by changing the root user's login shell.

    All the services that start up (eg. crond) are completely ignorant of what root's shell is set to. Services don't go through the process of logging-in as root and then spawning processes... They use the setting and environment they inherited from the rc* scripts, from start-up, while the system was single-user.

    Any programs or shell scripts you run once the system is multiuser as root, will be run with whatever interpreter they're set to use with the #! line. They don't know or care what your shell is.

    In short, there's practically no way that changing root's login shell to something different could possibly break anything. Now, if you do something stupid, like replace /bin/sh with something else, you'll break the whole damn system, but that's an idiotic mistake, and not how anybody should ever change a user's preferred shell.

    Actually, I'd say "two bonded/teamed/aggregated GbE NICs is good enough". That's half the throughput of your SSD, but you're probably not maxing out your SSD constantly, and you've got headroom for plenty of local disk I/O while you're at it. You could go for 4 bonded GbE NICs, and that'll cost far less than even a single 10GbE port.

    If we're talking about a SAN, sure, you probably want (multiple) 10GbE ports. But for anything else? Several hundred dollars per system to double your network throughput on the rare occasion you'll use it, probably isn't worthwhile.

    Transferring files between computers on a typical home network these days, I think the one gigabit per second network limitation is going to be the bottleneck for many people.

    Most people don't have SSDs. The LAN might be a limitation, but only just slightly, and not often enough that they're going to want to shell out a bunch of money to save a few seconds. And home users are probably on WiFi most of the time, not even maxing out a GbE link, let alone 10.

    Besides, there's bottlenecks and there's bottlenecks... Too little RAM is going to be painful. Too little disk iops may be painful. GbE? Just a minor slowdown, on occasion.

    If you don't know all about the dark corners of SQL backups and imports, manually doing SQL queries, navigating around schema, looking for inconsistencies, manually truncating log files, the implications of all of the above actions, and more, you don't actually have any SQL experience. That's not DBA stuff, that's just basic admin stuff.

    IMHO, there's no better experience than breaking shit. When some major service, with crazy service interdependencies just won't damn well start up, you'll quickly learn everything there is to know about that system, as you're tracking down the problem, step by step. Of course for some people in IT, sacrificing a goat, and just clicking random buttons, and doing a google search for the error messages they're getting is the only thing they can think to do, and they don't really get much benefit out of it. But for me, hammering on a system until it breaks in weird ways (even just filling-up a file system) and then figuring out how to systematically track down the problem, and going through the fixes, really is by far the most valuable IT knowledge.
