This is supposed to applicable to programming, not sure but I make a bookmark:
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.

I had a hunch that a web development problem had to do with different web elements historically being saved alternately in utf-8 and iso-8859-1. I decided to try tell the web server that my browser only accepted iso-8859-1, to see if I could trigger the bug.
I used the modify headers add-on for Firefox, and in it I specified like so:
I then verified on the server side that the headers were indeed altered.
The bug I was trying to find? Turned out not to have to do with this.
Add, modify and filter the HTTP request headers sent to web servers. This addon is particularly useful for Mobile web development, HTTP testing and privacy.

I'm not exactly sure what Livecode is, but I know what it looks like - Hypertalk, the language used in Apple's venerable HyperCard and its ilks (such as SuperCard). I was a professional HyperCard programmer at one time. I found Livecode while searching for text processing code for Javascript. This brings back memories. I liked Hypertalk.

I have used this to figure out what is happening in complex pieces of software, such as Plone.
The hook is set via the sys.settrace() function. This takes a function which is called during any of several events. One is the "line" event. Before the interpreter executes a line it calls the trace function with the current frame and the string "line". (The function gets a third argument which is None; that fields is used by other events.
import sys
import linecache
def traceit(frame, event, arg):
if event == "line":
lineno = frame.f_lineno
filename = frame.f_globals["__file__"]
if (filename.endswith(".pyc") or
filename.endswith(".pyo")):
filename = filename[:-1]
name = frame.f_globals["__name__"]
line = linecache.getline(filename, lineno)
print "%s:%s: %s" % (name, lineno, line.rstrip())
return traceit
You start the tracing by calling the function defined above:
sys.settrace(traceit)
...and then your code follows.

Here is a version I made some years ago, that probably works. It seems to track function calls:
def traceit(frame, event, arg):
fo = open('/tmp/recur_log','a')
if event != 'call':
return
co = frame.f_code
func_name = co.co_name
if func_name == 'write':
# Ignore write() calls from print statements
return
func_line_no = frame.f_lineno
func_filename = co.co_filename
caller = frame.f_back
caller_line_no = caller.f_lineno
caller_filename = caller.f_code.co_filename
fo.write( 'Call to %s on line %s of %s from line %s of %s\n' % (func_name, func_line_no, func_filename, caller_line_no, caller_filename))
fo.close()
return traceit
It doesn't seem to extract the module name though, can be done with:
name = frame.f_globals["__name__"]

collective.eggproxy is a smart mirror for PyPI. It will collect packages on PyPI only when a program like easy_install or zc.buildout asks for it. In other words, unlike some mirrors that act like rsync and get the whole PyPI base (more than 5 gigas) collective.eggproxy will only get what you need.

Med alla dåliga ekonomiska nyheter man läser så skulle man kunna tro att börsen skulle gå ner, men det gör den inte. Det finns till och med ett ordspråk myntat: "The market can stay irrational longer than you can stay solvent".
Jag lanserar härmed helghypotesen - att ingen vill må dåligt på helgen. Under varje vecka fram till jul kommer börsen att stiga från måndag till fredag så att alla kan må bra på helgen. Under helgen görs politiska och ekonomiska åtgärder som får börsen att öppna nedåt på följande måndag.
Denna cykel rullar på mot jul. Julen är också en helg och ju närmare julen man kommer, desto bättre vill man må under julen. Alltså går börsen upp framemot jul.
Sedan går det åt pipan!
Today on a temporary test setup I had the need for Apache to serve out sites on the same IP number, but on different ports (due to inflexible port forwarding on a router). According to the Apache documentation, NameVirtualHost can be written without a port specification.
NameVirtualHost *
However if you do so on Ubuntu 10.10 with some virtual hosts defined with ports, you get:
[error] VirtualHost *:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported,
proceeding with undefined results
Putting in more than one NameVirtualHost, with different port numbers covering the ports used in the virtual hosts directives, gives no errors though:
NameVirtualHost *:80
NameVirtualHost *:8080
And seems to work. You need to tell Apache to listen to all ports specified too.
