Jitsi – FreeBSD Wiki

Posted: May 22, 2016 at 10:44 pm

UPDATE

Audio and video now works. I have also sent some patches to the Jitsi project in order to make the work of the port easier. I will update the port soon. As soon as everything is done, this page will be probably deleted.

Jitsi is an open source VoIP and IM application. It supports several popular protocols (most notable SIP and XMPP), and offers encrypted chat (OTR) and encrypted voice and video calls (ZRTP). It is mostly written in Java (Swing for the GUI also) with some parts written in C because it uses a plethora of third-party libraries in order to be multiplatform (when Java fails, the third-party libraries come to the rescue).

The purpose of this page is to serve as a starting and coordination point for anyone that wants to help in the process of integrating Jitsi into FreeBSD. Throughout the years, the Jitsi mailing lists have received emails from several people who were trying to port Jitsi on FreeBSD with working audio/video calls, but as far as I know, at the moment we don't have such a thing.

Jitsi 2.2 (latest stable version) exists in the Ports tree under net-im/jitsi.

Unfortunately, the new version (2.2) that exists in the Ports tree, does not solve any of the existing problems. The current problems are:

I think that this is the issue with the highest priority. If we fix the audio, probably we will be able to make encrypted voice calls - one of the most useful features.

Jitsi supports 3 audio systems:

On a Debian GNU/Linux system, Jitsi offers 2 audio systems: PortAudio and PulseAudio. On a Windows 7 system it also offers WASAPI (Windows only). In FreeBSD, I assume that it is possible to have both PortAudio and PulseAudio.

The reason that the number of features of Jitsi differs from one platform to another is that in the lib/native directory of the source of Jitsi, there are directories for every platform (i.e. freebsd, freebsd-64, linux, linux-64, mac, solaris, solaris-sparc, windows, windows-64). Every platform has a different number of libraries inside. For example, the freebsd directory has 5 libraries whereas the linux directory has 24 (including both the libjnportaudio.so and the libjnpulseaudio.so that are responsible for the available audio systems in Jitsi). If you are on a Debian GNU/Linux amd64 system running Jitsi from source, and you remove the libjnportaudio.so library from the linux-64 directory, you won't be able to have the PortAudio option in the available audio systems of Jitsi.

So there are 2 options (that I can see):

In order to build the libjnportaudio.so library, you have to download the source of libjitsi (https://jitsi.org/Projects/LibJitsi). Then, the procedure can be summarized in the following steps:

Download the hotplug branch of PortAudio (check src/native/portaudio/README), patch it with the src/native/portaudio/portaudio-hotplug-os.patch, configure and make.

If you follow the above procedure in an officially Jitsi supported platform (ex. Debian GNU/Linux i386), the chances are that you will end up with a libjnportaudio.so file under the lib/native/linux directory of libjitsi.

The procedure is a lot easier than in libjnportaudio.so. It basically needs three things:

Some minor changes to the target pulseaudio of the src/native/build.xml in order to compile under FreeBSD

Invoke the command ant pulseaudio inside the root directory of libjitsi

I have produced the libjnpulseaudio.so library but when I placed it under the directory lib/native/freebsd-64 of Jitsi I did not get PulseAudio in the drop down menu of Audio Systems. Probably it needs some changes in the Java files in order to detect it (TODO)?

A-DNA – Wikipedia, the free encyclopedia

Posted: at 8:48 pm

A-DNA is one of the possible double helical structures which DNA can adopt. A-DNA is thought to be one of three biologically active double helical structures along with B-DNA and Z-DNA. It is a right-handed double helix fairly similar to the more common B-DNA form, but with a shorter, more compact helical structure whose base pairs are not perpendicular to the helix-axis as in B-DNA. It was discovered by Rosalind Franklin, who also named the A and B forms. She showed that DNA is driven into the A form when under dehydrating conditions. Such conditions are commonly used in to form crystals, and many DNA crystal structures are in the A form. The same helical conformation occurs in double-stranded RNAs, and in DNA-RNA hybrid double helices.

A-DNA is fairly similar to B-DNA given that it is a right-handed double helix with major and minor grooves. However, as shown in the comparison table below, there is a slight increase in the number of base pairs (bp) per turn (resulting in a smaller twist angle), and smaller rise per base pair (making A-DNA 20-25% shorter than B-DNA). The major groove of A-DNA is deep and narrow, while the minor groove is wide and shallow.

Dehydration of DNA drives it into the A form, and this apparently protects DNA under conditions such as the extreme desiccation of bacteria.[1] Protein binding can also strip solvent off of DNA and convert it to the A form, as revealed by the structure of a rod-shaped virus.[2]

It has been proposed that the motors that package double-stranded DNA in bacteriophages exploit the fact that A-DNA is shorter than B-DNA, and that conformational changes in the DNA itself are the source of the large forces generated by these motors.[3] In this model, ATP hydrolysis is used to drive protein conformational changes that alternatively dehydrate and rehydrate the DNA, and the DNA shortening/lengthening cycle is coupled to a protein-DNA grip/release cycle to generate the forward motion that moves DNA into the capsid.

Psoriasis – Better Health Channel

Posted: at 8:47 pm

Psoriasis is an inflammatory skin condition. It is not contagious. Symptoms include red scaly patches on skin, itchiness and flaking of the skin. Psoriasis can also affect the nails and may cause arthritis (psoriatic arthritis). About 10 per cent of affected people have all three.

There is no cure for psoriasis, but it can be well controlled with treatment.

Around 30 per cent of people affected by psoriasis will be able to identify relatives who have or have had psoriasis. A number of genes with psoriasis susceptibility have been identified recently.

Environmental events can trigger episodes of psoriasis in people with an inherited susceptibility to the condition. These may include:

The areas that are most commonly affected are the scalp, elbows and knees, but skin psoriasis can occur anywhere on the body.

Symptoms of skin psoriasis vary from person to person. The effects may include:

Psoriasis (cont.) Psoriasis Treatment

Psoriasis is a chronic skin condition that may worsen and improve in cycles. Any approach to the treatment of this disease must be considered for the long term. Treatment regimens must be individualized according to age, sex, occupation, personal motivation, other health conditions, and available resources. Disease severity is defined not only by the number and extent of plaques present but also by the patient's perception and acceptance of the disease. Treatment must be designed with the patient's specific expectations in mind, rather than focusing only on the extent of body surface area involved.

Many treatments exist for psoriasis. However, the construction of an effective therapeutic regimen is not necessarily complicated.

There are three basic types of treatments for psoriasis: (1) topical therapy (drugs used on the skin), (2) phototherapy (light therapy), and (3) systemic therapy (drugs taken into the body). All of these treatments may be used alone or in combination.
