Your provider is half the equation, but having a solid, easy to use on-premise system that auto-configures your phones( including mobile), sets up QoS properly, lets you easily connect to a variety of providers and offers all the unified communications features of large enterprise systems is important as well. A product I was involved with does this, check out jazinga.com

Just to add to Tsahi's answer which is totally correct, codecs like MP3, AAC and VORBIS have very high delays, typically in the 80 to 200ms range when optimized; they sacrifice lower latency for higher fidelity. For communications, you really want to be in the 5 to 50ms range and there is still room for a lot of innovation for bringing HD voice to communications, specially given how networks are evolving. The best we have right now in actual devices is low delay variants of AAC and certain variants of G.722.

Without a doubt, Linux is more ideal for running Python web apps, but it's actually not a bad idea at all to develop your app on a Windows platform. If you build a nice portable code base that runs nicely on both Windows and Linux, without unnecessary tinkering, you are going to end up with a better product that is easier to configure with a cleaner design. It will definitely make the learning curve for any new developers that work on it smaller. Even with Python, you would be surprised how easy it is to end up with something that is essentially platform specific, specially if it involves anything interesting beyond simple CMS type apps. In my experience, it's a good idea to avoid this.

I think you have made a mistake and the ad was for a developer of a product/service used by business analysts. It would be common to prefer someone with some familiarity in the problem domain. Nobody would actually expect someone hired for a business analyst role to understand how Hadoop works, or what it is even. If by business person you meant a businessman or a product line manager, etc, then it would make even less sense, unless the company was in the business of big data, data mining, etc. and even then I don't think they would ask for this specific combination.

All the points in Bruce Alderson's answer to Web Development: What are some best practices for mobile web development to reduce bandwidth usage? are good. Also, I would recommend to design your app in a very asynchronous fashion. I think that you should really consider all the persistance, caching and the offline storage facilities available to you carefully when designing mobile web apps. Finally, I'm personally not a big fan of responsive layouts, although they are better than nothing, I think you should have seperate UI's specific for device classes that don't need to wait around OFTEN for data over the network to be usefull.

I think Voxeo implements (among many other interfaces) some of the OneAPI interfaces, I don't remember which brand they use but you can contact them. OneAPI is a typical "go nowhere, don't rock the boat, but lets pretend we are really earning our paychecks" telco initiative and just as pathetic as when people called it Parlay, I wouldn't bet my time and effort on it if I were you.

In my opinion, you want to have a light working knowledge of a few. Knowing R, Python, a bit of spreadsheet scripting and a grasp of web page programming with jQuery can be useful for any scientist .

I don't think it's a matter of acceptance, the only limiting factor in developing countries is the hardware required to turn phones into a platforms, as opposed to what we still have today; limited purpose feature phones. In less than 18 months, the crappiest feature phone will be an Android device that's considerably more powerful than an IPhone 3S. I don't think developing countries will have any problems adopting the technologies you mention.

At one of my companies, over the last couple of years, we developed the first high def IMS based video-conferencing solution for a number of IPTV and Digital TV platforms. Getting lip-syncing right was very challenging. Even though Audio Codecs are more complex than video, I think right now the next hardest thing to work on after synchronization, is encoding video on mobile and IPTV platforms. I should say, I don't think this will remain a challenge for long given how powerful SoC's are becoming for both. If anyone wants a solution for high def conferencing on Sigma Designs, Trident Microsystems and ViXS platforms without using an external encoder BTW, feel free to contact me.

In the late 1970′s and early 1980′s, fiber optics came into play and a significant number of the companies deploying these came from or were funded by institutions outside of telecoms, like large construction companies. They lobbied against the incumbent (monopoly) telcos and wanted to also offer phone services using their lines. This eventually led in the mid-1990′s to regulations mandating telcos to open up everything, including the last mile to competition.

There is clear indication from initiatives like schema.org, Opengraph, science and engineering (bioinformatics, etc) and the evolution of web API’s from popular service providers, that DL will be common in web pages and a good foundation to bet on for the future.

So, in my opinion, the short answer to your question is “No”, but larger organizations are beginning to jump on board.
