    [MYSTERY SOLVED] What does "echo ???????????????" really do?

    It would probably have been more obvious if I hadn't had the impression that it was somehow echoing history entries, for some reason.

    Is there any accurate way to rank distros?

    First, great post, because it provokes thought. Thank you.

    In addition to what rocker357 said, there is also this:

    Distros--well, computer OS's--can be used for so many different purposes that I think a single ranking scale is whistling in the wind.

    There are not just server and home use.

    There are business servers, web servers, and file servers. They are all servers, but they serve(r) different purposes and would be evaluated using different criteria. There is also office use (documents and general business), office use (accounting), office use (engineering and design), audio-visual and/or graphic creation and editing, general home use (email, web, some documents, photo editing), and those are just the ones off the top of my head. Each usage would necessitate a different weighting of metrics.

    And, frankly, it's not so much the distro that matters as the application suite, because every distro still has the Linux kernel at its core.

    Distrowatch's method is sort of a popularity poll and doesn't pretend to be anything more. It's meaningless fun, like a carny game.

    Just my two cents.

    If you figure out a way to remove response bias (any bias, honestly) you would likely win some awards and worldwide recognition. I'm going to go out on a limb and say that since no one has solved this one yet, odds are pretty good we'll be dealing with bias for many, many years to come.

    Not to say the ideas presented are without merit, of course =) Your first duty would be to define "ranking" very precisely so you have some hope of achieving a goal instead of floundering about some vague concept of "better".

    erm,
    I don't know why that didn't "click" earlier.

    Glad it worked out.

    [MYSTERY SOLVED] What does "echo ???????????????" really do?

    Code:
    18:07 dsc / $ \echo ????
    boot home proc root sbin
    (Didn't know this inverted dash shorthand for the non-aliased executable, cool)

    Just noticed something similar happens even with printf, with a less "parsed" output (no newlines, as usual), and somewhat different as well:

    Code:
    18:12 dsc / $ printf ????
    boot18:12 dsc / $ 
    18:12 dsc / $ \printf ????
    boot18:12 dsc / $ 
    18:12 dsc / $

    And also with plain bash (I guess):

    Code:
    18:43 dsc / $ bash --norc
    bash-4.3$ echo ????
    boot home proc root sbin
    bash-4.3$

    Eventually I'll boot on Debian to see if it does the same.

    Still on Ubuntu Wily, the mystery-folder/file through "?????" is also present in other commands, such as ls:

    Code:
    18:57 dsc / $ echo ???
    bin dev etc lib mnt opt run smb srv sys tmp usr var
    18:57 dsc / $ ls -1 ???
    bin:
    bash
    bunzip2
    bzcat
    
    [...]

    I can appreciate honest questions but I'm not wanting to get into a debate here again.

    Studies have shown that atheist and believers brains use different pathways to process religious thought, typically with believers it is either pathways that regulate fear or are used for language, whereas for atheists and agnostics it tends to be with pathways associated with visual processing.

    Would an all powerful loving God cast me into hell simply because my brain is *literally* wired differently than yours?

    But ultimately, at the same time, He's given you the free will to choose Him or not. He can convict you of your need for Him but the choice to agree with Him and receive Him is up to you.

    Both of those links state that it is God's responsibility for convincing non-believers.

    If I am reading this correctly, would it be right for me to stand on judgement day in front of God and ask God why he didn't convince me?

    It is hard to argue with:

    "that God will convict her of her self-righteousness and her need for Christ"

    and

    "You can’t convince people to enter into that relationship. That is God’s responsibility."

    Am I missing something?

    (This is an honest question, I'm not trying to derail your blog again).
    Hey, my man!

    I was reading through this blog just now and I saw this question and I apologize that I didn't answer it. I think this was an honest question.

    The short answer to this would be that it's not us that does the "convincing," it's God's. Our job is simply to present the truth of Jesus Christ with others. Here are a couple articles that explain that concept in greater detail, if you'd like to read them...

    Again, I apologize for not answering this earlier.

    RaspEX Build 160402: Now with Kodi (XBMC) Media Center, Bluetooth, Samba, SSH and VNC4Server

    Comment about RaspEX at SourceForge.net 160407

    "I have tried nearly all the operating systems for the Raspberry Pi 2 and 3 some are good some not so good...but head and shoulders the best by a long long way is RaspEX.....I downloaded it last night actually very early in the morning and after wasting time trying to get the networking to work sent the author a help me email. He responded very quickly and after I had reviewed my own stupidity it worked a charm. It is very fast and very familiar if you know the Debian/Ubuntu world. I urge all Raspberry Pi owners to try it you will not be disappointed."

    Ahhh, ok, gotcha! Thank you for explaining that. If you would, please report back later and let us know how it goes.

It goes without saying that my daughter does not have access to the firewall configuration =)

    I originally had each Windows machine on its own /30 (i.e. 4 addresses: network, gateway, host, and broadcast), but then I wanted to add the 2801 without tons of traffic logic on the firewall, so I remapped that portion of the network to be /29's (8 addresses: network, gateway, 2801, host, 3x unused, and broadcast), which gives me room for expansion later, should I choose to do so.

    Really, all relayd does here is TLS validation and checking URLs against a whitelist, which is something I've been meaning to add for a while now.

    Hi...

    Out of curiosity, what is that upstream point? A particular server? I'm guessing a part of your goal is to keep any kind ability to make settings adjustments (or file changes) away from your daughter's system. But if the file (or code) you mentioned (in your first post) is on her system, how do you keep her from making changes to it? Please bear with me, my understanding of networking is very poor. I'm mostly a hardware guy.

    I have very little understanding of what's being said but I found some sites that deal with the relayd and layer 7, although they're not directly related to what you're doing...
