I am currently researching wireless microphones for video presentations. I considered lavalier type microphones, which you clip on to your clothing, but decided to go for the earmic type, where the microphone is mounted on a wire around your ear.

To me the earmic seems to be in a position that is more predictable than clipping a lavalier mic onto whatever clothing you may be wearing at the moment. Ear mics may possibly pick up smacking and hissing from your mouth as you are talking to a larger degree than a lavalier type mice would, but I will take that risk. A lavalier type microphone also has the problem of picking up noise as it scratches towards your clothes.

These ones I've found interesting so far:

AKG WMS 40 Mini Earmic ISM3 - Thomann UK (~ €100)

the t.bone TWS Headset 863 MHz - Thomann UK (~ €100)

the t.bone TWS One C Headset - Thomann Sverige(~ €50)

t.bone is Thomann's own brand, apparently AKG compatible on the mic connector side. The AKG seems to have better sound quality

If you are on Skype 4.2, it has stopped working on Linux. You will not get an upgrade message, just a cryptic "Can't connect" message. The recommended solution is to upgrade to 4.3, which is supported by Microsoft. However that alone did not work for me, even when uninstalling the old version with "purge" (getting rid of old config files).

I also needed to delete the hidden Skype folder in my home directory:

 

First get rid of the old skype from repo: sudo apt-get purge skype Second, delete your ~/.Skype folder rm -R ~/.Skype

Basically when painting in two colours with masking tape, after you have done the masking over the "Base" colour, paint the base colour again on the non masked areas where you want the accent colour, let it dry an apply the accent colour. In this way the base colour will bleed under the tape, and seal and prevent bleeding from the accent colour.

 

The base is the color that's under the tape. Doing it this way lets that color bleed under the tape, but you won't see it because that's what color that part of the wall already is.

I run a custom-designed and developed system on my webforms. While the implementation is typically specific to a site, CMS, forms plugin, or what have you, the concepts behind it are general enough to be applied anywhere you have a form. It doesn't prevent 100% of spam, but by targeting the primary behaviors spambots use it prevents the majority of spam on web forms. There's two basic behavior-blocking elements at play in it:

How can you have a global object or variable that you can share across modules in python? Each module in python has its own name space and is happily unaware of anything defined in the others' name spaces. You can however import a variable from another name space, and then you can modify that and it will be visible in other modules that do the same. Except that you can't, because now it is in your name space and not the same as what the others have imported. What you can do however is to import the module in which it is defined, and then it gets changed everywhere.

Basically this won't work:

from flum import bletch

bletch = 67

That change will not be picked up by any other modules that do the same kind of import.

But this will work:

import flum

flum.bletch = 67

Because there is only one instance of each module, any changes made to the module object get reflected everywhere. For example:

But in a report on Tuesday, researchers at Harvard and Yale universities argue that the benefits of the work are outweighed by the risk of pathogenic strains escaping from laboratories and spreading around the world. They calculate that if 10 high-containment labs in the US performed such experiments for 10 years, the chance of at least one person becoming infected was nearly 20%. If an infected person left the laboratory, the virus might then spread more widely.

Verkar det som, mycket intressant om de kommer nånvart med detta:

Summary:

openssl version

With the recent disclosure of the long standing heartbleed bug, it is a god idea to check what version of openSSL you are actually running. Just type openssl on the command line followed by the word "version". According to this page, the versions that are compromised are

• OpenSSL 1.0.1 through 1.0.1f (inclusive)

OpenSSL cheat sheet

Well actually two, but you stick them in one file that gets executed in bash:

ssh -fN  -L 5900:localhost:5900 remotserver.example.com
vncviewer -encoding tight -quality 5 localhost:0

The -N switch prevents commands to be sent to the remote host, the -f switch allows the terminal to come back and prompt for a vnc password that is triggered by the second line.

Warning: Haven't figured out how to exit cleanly. However the top rated answer here might do the trick:

Tightvnc used in this case:

It gets harder and harder to install a python 2.4 buildout on Ubuntu and Debian. Basically, the different scripts involved will try to execute code that is not compatible with python 2.4 at every step of the way. I need python 2.4 for some old Plone 2.5 sites. Here is what I did to get it running this time, tested both on Ubuntu 10.4 and Debian 7:

Use a separate virtualenv script, so do not rely on the one installed in the system which is made for another python version. Instead download a standalone script of some vintage:

wget --no-check-certificate https://raw.github.com/pypa/virtualenv/1.7.2/virtualenv.py

Setup the virtual environment like so:

python2.4 virtualenv.py .

It will crash when trying to install setuptools, but by then it has installed python.

Now you should have a working python.

Time to install a setuptools that actually works. Version 1.4.2 works (somewhat selected at random, you can try newer ones if you like). That version is not linked from the https://pypi.python.org/pypi/setuptools page, but with some detective work it can be found at:

https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz

Download and unpack it and install it in the old-fashioned way:

./bin/python setuptools-1.4.2/setup.py install

Time to install easy_install. Download the script from:

http://peak.telecommunity.com/dist/ez_setup.py

Then install easy_install with:

./bin/python ez_setup.py

Time to install zc.buildout:

./bin/easy_install zc.buildout==1.4.4

In your buildout.cfg file, you must also pin setuptools to the version you have installed. Otherwise, you guessed it, zc.buildout will download and fail to run a newer incompatible version of setuptools:

[versions]

setuptools = 1.4.2

And there you go:

./bin/buildout
