Most of the findings in this entry are from personal reflection from my experience with the above community source projects, talking with colleagues involved in a variety of open source projects, and blogs and writing from across the web.

Delightful software in community&Open source software

When I first heard my fellow Sakai board member, CIO Brad Wheeler from Indiana University, refer to “user delight” as a strategic goal, I was slightly uncomfortable. The term “usability” is so much more utilitarian and sets a nice solid, non-evocative baseline. Don’t get me wrong, I want the BEST user experience possible, but “delight?” So I ask you, why not “user delight?” In fact, shouldn’t usable software simply be the bottom line? If we are going to be in the software development business, shouldn’t we be aiming to, at the very least, satisfy, and even better, create an experience that is welcomed — even sought after! Wouldn’t that be success?! In fact, when I step beyond my prudishness and my fear of failure, I do agree with Brad. Community and open source communities, where higher ed IT shops are striving to create superior software “by academia and for academia” are ideally positioned (at least theoretically) to achieve user delight. However, in order to do this we need to carefully examine the skills and resources and sometimes-unusual alliances that may be required to be successful in achieving this goal.

To begin, let’s be clear, poor usability in software applications is not relegated solely to the domain of open source. Many a commercial product has been slotted for demise – often prior to launch — because of poor usability. Indeed, as evidenced in many a UI listserv, UI design faces challenges in communicating its value across the spectrum of workplaces (spend a day or so on the IXDA list to observe this). Clearly usability problems are not the sole reason for what is reportedly an over 70% failure rate of software projects. But I would hazard to guess that if you are willing to broadly define usability as “a useful and satisfied user experience (UX),” and not just solely issues related to interface design, that a large portion of these failures are likely to indeed be tracked back to usability. While many of the symptoms experienced by commercial and open source development teams are similar, I expect that the solutions applied will often, and necessarily, be different in order to accommodate the cultural and organizational differences between the environments, as reflected in Eric S. Raymond’s “ The Cathedral and the Bazaar .”

I have attempted to outline some of the challenges to the development of a delightful user experience in OSS and Community Source products from the perspective of those projects coming out of higher education for higher education. Many of these issues are interlacing and multi-layered and I don’t expect to create an all encompassing list, but to at least capture a general survey of some of the salient points.

Distributed development teams — the good, the bad, and the inevitable

One of the huge benefits of developing open source products is that development can happen anywhere — and hopefully it does! In order to enable these distributed development teams to deliver in a timely manner, it is often necessary to create frameworks that allow the creation an implementation of loosely coupled tools. From many perspectives, this is a good thing to do: organizationally it allows open source teams to work efficiently (eliminate the coordination costs), and architecturally it provides much greater flexibility.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help
But this is not salma it's Faiza live in lousvile Ky I garbage this so I am going collage with JCTC that the of the collage thank you my friends

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
