Hello SekeRob,
 We have 23 chromosome pairs but 24 chromosome types. The sex chromosomes come in X and Y flavors, so we have to examine 24 chromosome types.You are the first to comment on this. You have an eye for detail.  Lawrence |

I have no Linux beard so when I find interesting pages I tend to bookmark them...
----------------------------------------I have not had a chance to try this but when searching I found the following info on ghacks.net http://www.ghacks.net/2010/03/11/wha...on-of-apt-get/ I found it interesting and thought to just paste the necessary here with thanks from me to the author. First I want to compare the two apt-get options: upgrade and dist-upgrade. The difference between these two is very simple. The upgrade option is used only to install all of the newest versions of the packages already installed on your machine. This is what happens when you see the upgrade upgrade packages through the Update Manager (You know, when you are made aware of notification in your panel and then Update Manager opens to show you which updates are available for your system.) The dist-upgrade option is quite different from upgrade. But just what does dist-upgrade do? Simple. The dist-upgrade option not only will upgrade all of the currently installed packages on your system it will also handle the dependency changes with new versions of packages. In other words, dist-upgrade will remove obsolete packages from your system, whereas upgrade will not. This function is out of necessity for upgrading from one distribution release to another. But doesn't it upgrade my distro? Not necessarily. Although, by itself, dist-upgrade, will prepare your system for a distribution upgrade, the only way it will actually perform the upgrade to a new release is if you have changed your /etc/apt/sources.listfile to reflect the change. In other words, you have to add the repositories for the new distribution in the sources.list file before this can happen. Well that sounds simple. Yes it is. But it is not the recommended plan of attack for upgrading to a new distribution. Although it will work, there is a better way...by command. The command do-release-upgrade was created specifically for upgrading the operating system to the latest release via the command line. Of course, before you issue this command you will want to check to see if an upgrade is available with the command sudo do-release-upgrade -d. When you do this you you be informed if a new release is available. If there is a new release available issue the command sudo do-release-upgrade and the upgrade process will begin. Of course this is a rather lengthy process and there are risks involved.You could lose packages you have manually installed (that are not supported by the new release) or (worst case scenario) your system could become unstable. Distribution upgrades are always tricky. I have had them go exceedingly well and I have had them go very awry. It's a gamble. But now you know exactly how to manage the task from the command line. You are now, officially, dangerous.  |

The Linux Cinnamon flavor gets the occasional mention and though I'm quite contend with Unity, installed the latest Cinnamon 2.0 over all, which is now -not- breaking Unity.
Cinnamon 2.0 Released, Becomes An `Entire Desktop Environment` http://www.webupd8.org/2013/10/cinnamon-20-released-becomes-entire.html Cinnamon 2.0 No Longer Breaks Unity In Ubuntu 13.10 [Quick Update] http://www.webupd8.org/2013/11/cinnamon-20-no-longer-breaks-unity-in.html If it does what it's said to not do, will post again.  |

Ubuntu 14.04 will [likely] have fstrim cron job for SSDs: http://www.phoronix.com/scan.php?page=news_item&px=MTUxOTY .
----------------------------------------edit: And the 16th comment says: 200TB is nothing. SSDs can take over 1500TB of write performance. http://www.xtremesystems.org/forums/...e-25nm-Vs-34nm You are basically never going to write your SSD to death.

Got Cinnamon 2.0 [aka Mint 16 interface], as posted about few up, on top of Ubuntu with the 3.11.0.14 kernel. Like it, highly configurable, bit retro, lower resource use [more cycles left for BOINC when the GUI is loaded]. Suddenly certain network functions started to work which would not since the 13.10 clean install, and liking Nemo with the breadcrumb addressbar structure as replacement to Nautilus. Other than that, nothing much exciting going on in Linux world [Valve's SteamOS for gamers maybe ;-]

A Ubuntu 13.10 review http://www.networkworld.com/reviews/2013/120913-ubuntu-test-276581.html?hpg1=bn
Stable for me, still using the Cinnamon 2.0, Mint 16 equivalent interface though (when the device is on and booted into Linux. It's in stasis now as a power reduction measure... replaced by a 4770, doing 2-3 times the work, per core and twice the cores at that for >50W/h less. And looking forward to 14.04... it will have at least the 3.13 kernel with some serious improvements in the IO realm... and the earlier mentions Trim default on for SSDs (me new comp has a 1Tb drive with integrated 8GB SSD... can't wait to test-drive Linux on it... whence overcoming that MS UEFI boot blocker). |

A "how to" to set up auto-start of apps/programs after signing in and for many Linux flavors: http://xmodulo.com/2013/12/start-program-automatically-linux-desktop.html
Reminded me to go see if CLI Companion was ever updated to work again with the latest Ubuntu flavors. It stopped for me around 12.04. http://ubuntuforums.org/showthread.php?t=2131449 Loved that tool for it allowed to formulate terminal commands, even with asking to fill in variables and then pick them from a list, or get them as you type, then enter to execute. Much more convenient then scrolling through the terminal command history [never managed the easy recall way. Has anyone?] As one commenter notes... "I gotta have this in my linux distro, I'm 73 and can't remember sh......," |

Just curious how me new cruncher would do, as so far it's been doing near 3 times the amount of work the ol Q6600 did, for 30% less watts. Hooked up to WUProp to get some comparative stats, and was blown away by the specific MCM Windows v Linux... be astound [scroll down to near the bottom where WCG-MCM is]:
http://wuprop.boinc-af.org/results/compar_cpu.py?cpuid=1291 This 2x results suggests another maybe integer rich application [and that means closer suitability for something in the future ;]. Have most of the how to figured out, how to switch off the UEFI [simple BIOS flip to 'Legacy', and how to put Linux on with EFI enabled, so that will be the next step in optimizing throughput... twice as fast... got to have that if confirmed by hands on, the sooner the better. |

More laymen term news on the default 'Trim' functionality that will be in next Ubuntu 14.04, through a cron job. http://www.webupd8.org/2013/12/trim-enabled-by-default-for-ssds-on.html
Since me new cruncher has an SSD of 8GB integrated into the 1TB HD, curious if this will give a CEP2 improvement... under W8.1 there was a deterioration. On W7-64 machine with dual disk getting 99%, on the W8.1-64 getting at best 96%-97%, the startup phase is substantially worse... on W7 the CPU time starts counting after about 30-45 seconds on the W8 sometimes 3-4 minutes, and this is running only 1 at the time. Since 14.04 is still 4.5 months away, we could by then already be on CEP2v2... time will tell :D |

Time told us nothing
, but there's a new 14.04.02 LTS out with the 3.16 kernel instead of 3.13. Still supported till 2019, so that's what the sudo apt-get dist-upgrade will do next.http://www.pcworld.com/article/2888959/ubuntu...d-a-new-linux-kernel.html |
