Thank you for the great meeting today! Please keep the discussion going!
SIG-Computing: Windows Subsystem for Linux, and intro to SEMCO.org Google Apps
Windows 10 pricing will be $119 for Home edition after July 29, 2016. Install fest recommended in late June 2016 – email email@example.com
May “Patch Tuesday” patches expose the ”Get Windows 10” program again in Windows 7 and 8.1! If you wish to prevent upgrades, check out Steve Gibson’s website: https://www.grc.com/never10.htm
Mike recommended http://ultimateoutsider.com/downloads/
Web site maintainers, please patch OpenSSL and ImageMagick
Summer is a great time to get outdoors and away from computers, to interact with people more. Great time to take more pictures. Protect electronics from very hot temperatures and direct sunlight.
Ubuntu 16.04 LTS is out and will be covered at SIG-Linux today (4PM). Please be careful upgrading. Kevin O’Brien and some others have had trouble with the initial release. I suggest waiting for the 16.04.01 release in a few days.
New Nvidia Pascal GPU’s released. AMD Polaris coming end of May.
Windows 10 – Windows Subsystem for Linux
Windows NT heritage
A real subsystem with its own process tree
Limitations – as a subsystem there are barriers. Currently at least, file exchange may be awkward due to Linux v Windows carriage control, difference on allowed file names, and strong Windows file locking (Linux processes can access files while they are in use, in Windows that is more challenging), but Canonical and Microsoft have worked hard on these issues so far!
sudo apt-get install emacs — It works! Native Linux Emacs working on Windows!
ssh myusername@myhostname — very good, some terminal emulation glitches in the preview, but promising!
sftp mysername@myhostname:myfile /home/jeff/stuff/ — wow! Had to install PuTTY to do this in the past, and it was a bit slow. WSL version is fast and can handle huge files!
rsync — yay! Works on Windows paths under /mnt/c !
SEMCO’s Google Apps for NonProfits
Transitioning our semco.org email service to it
Data protection serivce level agreement is stronger than the consumer gmail.com service
YouTube, Google Drive (Sheets/Docs/Keep, etc.)
The No-No of semco.org
- None of us may use semco.org for any commercial use!
- Do not run a home business using Google Apps for NonProfits!
- Do not use it for consulting!
- With this said, though, it is no problem to apply what you learn using semco.org to your own site!
Groups may help us if Yahoo! Groups declines with the sale of Yahoo!
Having a @semco.org email address is a lot better than
Excellent collaboration facilities allow us to work together to create presentations, documentations, and yes, A SEMCO NEWSLETTER!
SIG-Linux: Ubuntu 16.04 LTS
ZFS – controversial licensing, but great to have stability in a scalable file system for Linux! The other alternatives are still very limited, but ZFS is very mature.
ZFS has awareness of solid state disks, may use them for caching or regular storage, with or without regular hard drives.
Improvements in the GUI
5 YEAR support lifetime!
Upgrade will be supported soon, but please do not upgrade right away. Please wait for the upcoming sub-release.
ZFS Demo in Ubuntu 16.04 LTS:
sudo zpool create testpool sdb sdc sdd –f # this will wipe disks, no redundancy!
sudo zpool list
RAIDz data redundancy (can handle loss of 1 drive, z2=2 lost, z3=3)
sudo zpool create testpool raidz sdb sdc sdd –f
sudo zpool status; sudo zpool list
sudo zpool add testpool spare sde # add spare drive
sudo zpool autoreplace=on testpool # allow auto use of spare drive
sudo zfs create testpool/jeff1 # Look, no partitioning needed!
sudo zfs list
sudo zfs set quota=5g testpool/jeff1 # you may resize this later!
sudo zfs set mountpoint=/home/jeff/jeff1 testpool/jeff1
# automatically mounts the file system, check ”mount”!
Other ZFS commands are available to export file systems via NFS, add/remove drives from pools, export and import, and do snapshots!
This is a promising release! Please visit http://www.ubuntu.com/ for other new features and to download it!
