Sugar Network

Collaboration support for Internet-less environments (but not only)

Harmonic Distribution

* The possibility to launch Base Software in heterogeneous
  software and hardware environments.
* Using Base Software, provide access to various Content
  (Sugar activities, artifacts created by Sugar activities, books, etc.)
  created within the Sugar community.
* Using Base Software, provide collaborative functionality to
  support Social activity around the Content.
* Instruments and workflows to adapt Content and Base Software
  to specific needs that Sugar Deployment might face,
  including extreme ones like off-line environments and restricting
  hardware.
  • [Sugar-devel] [SWEETS] Testing collaboration related fixes 05/07/2012
Hi all!
Following the plan for Harmonic Distribution v0.2 (which will be a basis
for Sugar Distribution to use in peruvian pilot), in Sugar Shell code
were made fixes that are intended to make Telepathy (everything related to
Neighbourhood view and Sugar Activities sharing/joining) more stable
(that was broken since global redesign started after 0.88 release).
Fixes are accessible from SweetsDistribution:Factory repository. Follow
regular Sweets Distribution installation instructions[1] to install
fixed Sugar Shell on all supported platforms[2].
Some visible changes in F1 view:
* the number of buddies should be increased from ~20 to 70-90
  some Sugar versions (maybe 0.90-0.92) don't publish information about
  nickname/colors on regular basis; this information are being stored on
  disk for now
* for some buddies, server still don't have information about colors
  (replaced by gray) and nick names (jabber ids)
If you have a time and want to help Puno deployment pilot, please,
consider possibility to install sweets-desktop from Factory repository
and do some testing of collaboration functionality.

Some tips:

* while interacting with another buddies, make sure that all
  participants use Sweets Distribution (some F1 buddies might misbehave)
* the good criteria of stability level of new Sugar is comparing with
  how collaboration happen in 0.88 Sugar.

BoxGrinder

BoxGrinder Build is an easy to use command line tool to create appliances (virtual images) from simple plaintext appliance definition files. BoxGrinder can produce appliances for a variety of virtual and cloud platforms using plugins supporting technologies such as VMware or EC2.

Pungi

Advanced
  • used to build non-live CD/DVD isos
Pungi needs to run on the arch it is composing, as root, and with an install of what it is composing, eg if you are composing Fedora 8, you need to be running Fedora 8.
This is so that the correct userland tools are used to create the images and such used by anaconda.
The eventual usage of pungi will most likely be in mock chroots to facilitate this.
It needs to run on the arch it is composing due to how anaconda-runtime determines what files to put in the boot images at this time.
Currently the releases of pungi are designed to run on an updated Rawhide system. Development of pungi always tracks Rawhide.
The following sections..." assume you have installed the mock package and prepared the mock chroot"

Build a boot.iso

  • "This section provides instruction on creating PXEboot and boot.iso images"

Build a DVD.iso

  • "This section assumes you have installed the mock package and prepared the mock chroot"

Koji

Click on title ^ to go to topic
(Very Advanced)
Koji is the software that builds RPM packages for the Fedora project

Mock

Mock creates chroots and builds packages in them. Its only task is to reliably populate a chroot and attempt to build a package in that chroot.

sugar-build

  • better j-build

Git

Advanced - Used by Sugar Developers
I installed Fedora 18 last night, and I have to say I like sugar-build
more and more.  With just this steps in a clean F18 you get Sugar
running and ready to hack each part of it:  Kudos Daniel Narvaez!
  Re: [Sugar-devel] F18.. go sugar-build, go! 01/18/2013 03:56 PM

L10n Translations

There is a git user named "pootle" that acts as the proxy by which all
PO file translations are committed from the Pootle server.  Please
make pootle a committer on the repo and I will make the connections
between git and the Pootle server.
Some "best practices" about working with git and Pootle are described here.

Dropbox working with the Journal

"If you don't have a Dropbox account, go to http://www.dropbox.com and sign up.  If you're a heavy Dropbox user,
I highly suggest creating another account just for the XO.
As with all things Linux, there are a few scenarios and use cases to consider. 
Here's a distillation, from the easiest installation and on.
1.  Gnome Desktop only, keeping Dropbox on the nand.  No USB drive required.
You're looking for an easy way to transfer notes, small files, etc. between the XO and your "regular" computers
 without having to constantly mess with USB drives.
2.  Gnome Desktop and usage under Sugar in the Terminal.  No USB drive.
The above scenario applies to you, but you'd also like to be able to access /home/olpc/Dropbox under Sugar in the Terminal.
3.  Up to 2 GB of storage as well as Sugar Journal integration.  USB drive required."

 When the IIAB registers via DHCP it advertises its name as "know", and if the DHCP server and the DNSserver talk to each other the DNS server will resolve the name.
dnsmasq does this, so I suspect that might be what School Server runs?)
The only down side to this is that if you reboot the school server,you may find you need to then reboot the IIAB device so it gets afresh DHCP lease because the school server may forget it exists. 
...

Tony Anderson:
The school server is gateway and dns for the XOs and can certainly resolve http://know to a fixed address, which is the more orthodox way to do this.
Incidentally, I believe the problem with the wiki is that the url is http://schoolserver/wiki4schools/ not http://schoolserver/wiki.
Normally, the XOs access everything from the Browse home page so that keyboard entry of urls is not needed. However, because of the xo-custom script problems this was not set up.

SD Card Install
This is a Fedora 17 Hard Float Trimslice Image suitable for writing to an SD card and placed in the Trimslice's Full Size SD slot (Front slot)
and booting without further modification.
Write with xzcat file.xz > /dev/mmcblkX, put in the device, and you're ready to go. Boots to a serial console.

Most of the SD card images can be used with a USB storage device drive using the following method:
Write the image to both the USB storage device and an SD card. IE, write the image using xzcat file.xz > /dev/sdX then xzcat file.xz > /dev/mmcblkX.
Once written, use a partition editor such as fdisk to delete the VFAT partition from the USB drive and the Linux partition from SD card.
Plug the SD and USB storage into your ARM device and power up. 
The ARM system will load any applicable bootloader pieces, kernel, and initramfs from the SD card, but use the USB storage for the root filesystem.

Nearly images are self-sufficient, but a kernel tarball is optionally available with the contents of the image's /boot and /lib/modules directories.
These can be used in conjunction with the tarball root filesystems to create your own images.

http://goo.gl/TSZxs
"On this device, both the recovery button and the dev-switch have been virtualized.
Our partners don't really like physical switches - they cost money, take up space on the motherboard, and require holes in the case.
To invoke Recovery mode, you hold down the ESC and Refresh keys and poke the Power button.
To enter Dev-mode you first invoke Recovery, and at the Recovery screen press Ctrl-D (there's no prompt - you have to know to do it).
It will ask you to confirm, then reboot into dev-mode.
Dev-mode works the same as always: It will show the scary boot screen and you need to press Ctrl-D or wait 30 seconds to continue booting.
You'll still have to run "crossystem dev_boot_usb=1" and reboot once to boot from USB drives with Ctrl-U. 
To leave Dev-mode and go back to normal mode, just follow the instructions at the scary boot screen. It will prompt you to confirm.
If you want to leave Dev-mode programmatically, you can run "crossystem disable_dev_request=1; reboot" from a root shell  .
Th ere's no way to enter Dev-mode programmatically, and just seeing the Recovery screen isn't enough -  
you have to use the three-finger salute which hard-resets the machine first.
 That's to prevent a remote attacker from tricking your machine into dev-mode without your knowledge.
An unrelated note: Holding just Refresh and poking the Power button hard-resets the machine without entering Recovery.
 That's occasionally useful, but use it with care - it doesn't sync the disk or shut down politely,
 so there's a nonzero chance of trashing the contents of your stateful partition."
