I've used Aircrack NG and Cain & Abel, and I find Wireshark confusing.

 

In other way, a Tux monument for SC4.

A fond hope for a native version, I guess.  Penguins never fly except underwater.

Ubuntu 15.04 Vivid Vervet released today, with all its flavors:

You beat me to it.  Took about two and a half hours to load and install the update.  Currently running:

 

Ubuntu 15.04 (vivid)

GNOME: 3.14.1 (Ubuntu 2015-03-18)

Kernel: 3.19.0-15-generic (#15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015)

wine-1.7.38

Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-4ubuntu4)

I'm totally amazed with Kubuntu 15.04 with KDE Plasma 5.3. It is awesome, even more faster than Plasma 4.x.

 

In other hands. What do you get if you combine the branch of Chrome, Chromium, and its OS project (Chrome OS, Chromium OS) and Ubuntu its last LTS?

A new OS: Chromixium OS 1.0.

It looks like Elementary OS (which some days ago released the stable version Freya, formerly Isis).

Since Chrome is owned by Google, I would be wary of dealing with such a rapacious outfit.

My nice, new, month-old Canon MG2520 all-in-one (no modem) that Canon refuses to support on Linux is working in all respects on Ubuntu 15.04.  On 14.10 there was a problem with the scanner section, but that is now working just fine thank you.

Linus Torvalds, principal author of the Linux kernel

 

[A Nonny Moose 8,263]

Linus wrote the Linux kernel because he didn't like Minix (and I agree).  It is a good way to learn operating systems because the whole source is published.

 

The only other kernel that I am aware of that is public domain is the Multics one from the early 1960s.  However, one does need to know PL/1 to understand that one.

 

When you really look at it, the purpose of an O/S kernel is to run the hardware and probably multitask it.  The scheduler is the trickiest part because it has to be gated (protected by semaphores) to prevent multiple processes from updating its queues simultaneously.  It is nice if the hardware has some co-operative commands to facilitate this, but it is not totally necessary.  The ring structure from the Multics hardware has evolved into the present ring structure in the x86 hardware.  Makes security much easier.

Tux the penguin, mascot of Linux

Penguins don't fly except under water, but they do compute.

I try to keep my machine up 24/7 and I only reboot if there is a kernel update.  Here is a demo of the BASH built-in w command.

This is Ubuntu 15.04.  It is the first time it has been stable (on 14.10 previously) for this long without a kernel update (or a power fail).

Ubuntu 15.04.  Uptime record for my machine.  Got a new kernel yesterday and had to boot.

Tue Sep  8 13:43:10 EDT 2015
 13:43:10 up 18 days, 22:06,  2 users,  load average: 0.11, 0.10, 0.17

 

It would seem that the mean time between kernel updates is around 18 days +

Updated to Ubuntu 15.10 today.  Console only as it didn't recognize my graphics hardware.  I am on 13.10 at the moment, waiting for either a fix or a denial.  I may have to spring for a new graphics card.

__________________________________________________________________________________

Update: When I booted 13.10 today I got an invite to upgrade to 14.04 LTS since 13.10 is out of support, so I did that.  Then I reached into the 15.10 partition and recovered my e-mail, calendar, and firefox stuff.  I've been fooling around getting games going, but this version has a 64-bit wine prefix, and I may have to do some handsprings.  Banished won't start even after patching.  SC4 starts OK now that I've updated the script to the 64-bit layout (windows: grrrr).  I have a feeling that I'll have to go to a 32-bit wine prefix to get this to work completely.

So far, a deafening silence from the distro on fixing my graphics problem, so I'll probably hop over to their forum and ask, but I suspect I am on the hook for a new graphics card.  Getting that put in by my favourite OEM will be a bit of a trial I think, since I no longer have the vision nor the manual dexterity to do it myself.

14.04 LTS is good for three years after April 30, 2014 so I am OK to 2017.  This could result in a whole new machine.
