We will do Plone training in London March 27-29. Same contents as usual, with the addition of Diazo skinning and Dexterity.
We will most likely be at Portman Square (depending a bit on the size of the group).

Note to self.
Python’s standard urllib2 module provides most of the HTTP capabilities you need, but the API is thoroughly broken. It was built for a different time — and a different web. It requires an enormous amount of work (even method overrides) to perform the simplest of tasks. Things shouldn’t be this way. Not in Python.

This looks very interesting for integrating external authentication sources. It seems to be a CGI script so it does not operate the same way as e.g. subversions's http protocol. I will probably need to install it and check the logs for what the requests will look like. My guess is a combination of path and POST parameters.
I believe this because it’s both efficient and can be run either secure and authenticated (https) or open and unauthenticated (http). It also has the huge advantage that most firewalls have those ports (80 and 443) open already and normal users don’t have to deal with ssh-keygen and the like. Once most clients have updated to at least v1.6.6, http will have a big place in the Git world.

Summary:
http://localhost:8080/manage_UndoForm?PrincipiaUndoBatchSize:int=660
....where 660 should be replaced with the number of transactions you need to go back. Then click like crazy.
I had the need to back a Zope site in time several months, October 2011 to be specific.
I had deleted a page (after its due date) for a Plone course December 2011 and kept one for December 2007. I did not, repeat not, want to enter everything that has changed in the contents of that course in between those two dates again. There are backups for the entire system but they are rotated, and I caught this late.
The course page is a compound content type consisting of sub objects for dates, pricing and other things. The missing course page had resided in a folder hierarchy that had also been deleted. The easiest would therefore be to just back the entire server in time, rather than trying to find specific edits to undo.
The undo page in the ZMI batches undoable transactions in lots of 20. My plan was to revert everything back to October 2011 (working on a copy of course). So, 20 transactions is not enough. I need a mega batch! I know there are command line scripts were I can find the byte offset for the date I am interested in and then use truncate, but haven't done it for ages (ok, once in 2002), and can the effect still be achieved from the ZMI? It will be an append but that's OK.
If you look at the "Earlier transactions" and "Later transactions" links, you can see that the start and end transactions are encoded as cgi parameters. The batch size is in other words, not hard coded. So, if the url for "Later transactions" on the second page is
http://localhost:8080/manage_UndoForm?first_transaction:int=0&last_transaction:int=20&PrincipiaUndoBatchSize:int=20
We can just change those numbers. So I clicked through "Earlier transactions" until I reached October, noted where I were in transaction numbers and did something like this:
http://localhost:8080/manage_UndoForm?first_transaction:int=0&last_transaction:int=660&PrincipiaUndoBatchSize:int=20
I got a big page and I did a lot of clicking of check boxes, and hit "Undo" - worked like a charm. I then copied over the oh so precious text to the production server.
"PrincipiaUndoBatchSize" I did not notice until now, it did not seem to overrule the other numbers; I did not change that one.
Hmmm, must go back and try something.... Yup, this works too:
http://localhost:8080/manage_UndoForm?PrincipiaUndoBatchSize:int=660
sudo shutdown -rF now
-or-
make a file in the root ("/") directory called forcefsck
Tested on Ubuntu 10.10 .
I had to forcefully shut down a laptop today, and when it came back to life it did not seem all that well. Sometimes Ubuntu starts a spontaneous disk check but it had no such intentions this time. I could not do a "live" disk check since the disk was mounted and fsck sternly warned that I *will* destroy things if I continue. Well then, how to direct it to do it on next boot?
There are at least two ways of doing this: By issuing a restart from the command line with shutdown command, where in addition to the restart flag one also issues a Force disk check. Or by creating a temporary file that Ubuntu reads as a kind of flag on boot and then deletes.

Avoid Flow. Do What Does Not Come Easy.
A new attack against home routers has been discovered, and an exploit tool has been made available. To disable WPS on a Netgear WNDR3700: Go to the admin interface, look at the Screen shot below: go to "Advanced Wireless Settings" and check the checkbox "Disable Router's PIN". Then click the "Apply" button.
(I have not verified that WPS is indeed disabled, but as long as the WNDR admin interface does what it says, it should be OK)
Just a day after security researcher Stefan Viehbock released details of a vulnerability in the WiFi Protected Setup (WPS) standard that enables attackers to recover the router PIN, a security firm has published an open-source tool capable of exploiting the vulnerability.

Microsoft provides virtual machine disk images to facilitate website testing in multiple versions of IE, regardless of the host operating system. Unfortunately, setting these virtual machines up without Microsoft's VirtualPC can be extremely difficult. The ievms scripts aim to facilitate that process using VirtualBox on Linux or OS X. With a single command, you can have IE7, IE8 and IE9 running in separate virtual machines

Why are there no GUI toolkits that simply do a away with clunky HTML form elements and instead manipulate the CANVAS element directly?
There are now implementations of VNC (noVNC, see my article here) and gtk that show that you can manipulate the canvas element pixel by pixel with enough speed to make it a fully fledged GUI.
A desktop user interface is vastly superior to HTML based user interfaces and with pixel-by-pixel control I could do so much better user interfaces for compound data and complex interactions. HTML is awkwardly retrofitted into service of something it was never intended to do.
So my question is, why not forego HTML elements completely and instead make something more like Qt, Gtk, Tk or wxwidgets in javascript for use directly inside a canvas element. You could even throw in a window manager there.
There is a question about this on Stackowerflow, but it was fielded back in 2009 and there aren't that many good answers posted, though Bespin is mentioned
Are there any GUI toolkits built on top of HTML Canvas like swing,swt,gtk or qt? So that it is possible to build applications like applets or flex gui:s inside the html canvas.
A comment on Reddit by Chris McDonough originally set me thinking:
"Many modern web apps are written largely in JavaScript (or even Objective-C on the iPhone) and the server side is just a glorified pack mule that schleps data to and from a persistence engine. Things change."
Ok, we are moving from generating the GUI server side on the web, to generating it in the user's browser.
I'm evaluating small linuxes, and have found two in the 10MB range: ttylinux and Tiny Core Linux. I have played a bit with tty, and will se what Tiny core can do.
Update: I have now tried Tiny Core and it crashed and burned through my VirtualBox and took down the entire laptop. Powerful stuff.
ttylinux, a small GNU/Linux system available for several CPU architectures. This small system has an 8 MB file system and runs on i486 computers within 28 MB of RAM, but provides a complete command line environment and is ready for Internet access.

If one of your virtualbox OS instances is hosed, you may still want to reach the files on it. You can actually mount the vdi file (the virtual disk image) on your Linux, and reach the files inside.
VirtualBox 4.0.x did not work for the following, I installed VirtualBox 4.1.6 .
Download gord-vbox-extras_1.0-4_i386 from here.
This will install vdfuse-v82a on your computer and in your path.
Make sure your user is in the fuse group, and that the line "user_allow_other" is commented in, in the /etc/fuse.conf preferences.
Figure out where the VDI file is that you want to mount. Let's say it is called "myvirtualmachine.vdi".
Make an empty directory to be the mount point of the volume that holds the file systems of your VDI image. Call it e.g. "mountpoint".
Mount the volume with:
vdfuse-v82a -f ~/VirtualBox\ VMs/myvirtualmachine/myvirtualmachine.vdi mountpoint/
Make a directory to hold the file system, call it e.g. "file-system".
Mount the file system there:
sudo mount mountpoint/EntireDisk file-system -o loop
This was enough for me, and all files are now visible and editable. I had put the OS directly on the entire disk in th evirtual machine. If there are partitions, maybe there is more mounting to do; I do not know.
You may need to use sudo to add and edit files, if their access restrictions don't match with your user id.
I have uploaded a new version of gord-vbox-extras to sourceforge. It now has zenity and nautilus and virtualbox-4.0 as formal dependencies. If you run KDE or something else, you can always unpack the package, rather than installing it.

Mikael Ståldal has written a guide of how to make a really small Debian that you can use as a basis for your virtual server.
It still includes networking, bash and most importantly, the Debian package management system. The latter sets it apart from many other small distros, that have their own package management systems. Although the image is still 256 MB, it only consumes 6MB of RAM, which is good for virtual servers, where RAM is one of the more scarce resources.
If one concentrates on virtual servers, it ought to be possible to rebuild and strip the kernel of code that caters for hardware not used. I guess one then needs to analyze what hardware the different virtual environments pretend to provide.
To build a minimal Debian based Linux system with a fully functional bash shell, TCP/IP networking and apt setup to be able to install any package from the Debian repositories. The resulting disk image will be about 256 MB and consume about 6 MB RAM.
