and get to know it later :-). Fast here: your prototype creation, not primary the database I/O. The general comments are right: there is no one-fits-all solution and the database might change. It looks very much like you also haven't decided on the server platform: Ruby, PHP... you could look at node.js or vert.x too - server side JavaScript is at least neat for prototyping (I'm not making a statement that is is *only* neat for prototyping - that's a completely different discussion). We did a number of super rapid prototypes with datasets roughly in the range you describe using CouchDB (not CouchBase!). There we took advantage of CouchApps - the ability to store the application itself inside the database - works like a charm when replicating data and you need a http server (Apache, NGix) for the URL mapping (which is already kind of optional) and CouchDB. You can authenticate with OAuth or via the Webserver and it replicates - so you can have local data easily (gold for testing). Since you can specify the direction I usually replicate all data from the server into local, but not the design. So I can try new app features local against the live dataset. It also does Map-Reduce using JavaScript. Give it a shot. If it can handle the data from CERN you also have quite a growth path. One fun project we did: run it on a Rasberry Pi to collect weather data from Arduinos all mounted in a small sail boat (the Pi in the cabin, the Arduinos on the masts). Occasionally when the Wifi or 3G shield picks up a network, it replicated back to a cloud server.

Besides the "god gave you one mouth, but two ears" most of the communication you will need is around negotiation. Here the Harvard Center for Negotiation published an excellent series of books: Getting to Yes, Getting past No, Difficult conversations, Lateral leadership and the Power of a positive NO. I wrote a little about it: http://www.wissel.net/stw/wisselblog.nsf/d6plinks/SHWL-6LR37S You also might want to check out Toastmasters who hone speaking skills or "The contrary public speaker". While they are not strictly about communication, they are about making your point understandable (litmus test: explain to a Rotary Club what a Social Graph is - they live it, but the don't use that lingo). Hope that helps

NotesSensei writes "My aging Lenovo W500 is up for replacement. I have a model with 1920x1200 screen resolution on a 15" screen and don't want to downgrade my display. Now I know the Chromebook Pixel and the Macbook Pro Retina go beyond the 1920x1080 found elsewhere, but I'd rather run a standard Laptop with a decent size SSD and Linux as my main OS.
Even the Alienware gamer laptops seem to be frozen in time at 1920x1080. A big screen doesn't harm, 20 years of staring took some toll on my eyesight, so 2400 pixels wide on a 13" monitor won't cut it.
What are my options?"

+ - New results indicate that particle discovered at CERN is a Higgs boson-> 1

Submitted by M3.14
M3.14 (1616191) writes "It seems that the statistic is more and more in favor of latest big LHC discovery being the Higgs boson everyone is expecting. There are still some unanswered questions though.
From the article: At the Moriond Conference, the ATLAS and CMS collaborations at CERN's Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year. Having analysed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles. It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model."

+ - What to do with a bricked Galaxy II 1

Submitted by
NotesSensei
NotesSensei writes "I have a Galaxy II that has been bricked by Samsung's customer service in Singapore. They demand S$400 to repair what might not be broken. What can I do with a Galaxy II that has a broken OS installation?

The full story:
One of my offsprings used a Galaxy II with Android 2.x and for a reason eluding me the OTA update to Android 4 didn't work. So we brought it to Samsung's customer service centre at Plaza Singapura. Despite the fact that I bought the unit in a shop in Singapore they claimed it to be a 'export unit' and only agreed to attempt an upgrade if I sign that they won't be responsible if they screw it. (So much for global warranty) And they did screw it. The unit powers on but the touch screen is unresponsive. They quoted S$400 to fix it.
I think that the OS upgrade just went wrong and the unit might be salvageable. What can I do?"
Programming

mikejuk (1801200) writes "If you are looking for a new framework to help you build a web site, then you need to know about Vanilla JS. This is the most powerful and lightweight of all the frameworks. It is already in use by a huge number of websites and autodownloaded by most browsers. Benchmarks show that the best alternative framework is less more than twice as slow and everyone's favourite jQuery is four times slower. Just think of all that speed you are giving up! Other benchmarks reveal an even bigger advantage for Vanilla JS ."

Diggester (2492316) writes "Tata Motors (an Indian car manufacturer) is changing things up with the first car to run on air, the Airpod.

The Airpod's technology was originally created in France at Motor Development International but has since been bought buy Tata in hopes to bring it to the Indian consumer car market. With virtually zero emissions and at the cost of about a penny per kilometer, it is definitely one of the most environmentally and economically friendly vehicles in the world. The tank holds about 175 liters of compressed air that can be filled at special stations or by activating the on-board electric motor to suck air in from the outside. Costing about $10,000, this car could beat out most smart cars from the market."

I don't have this with other browsers, have tried IE and FF, and it only seems to be the first time load of my homepage, other pages as well as reloading the home page work fine. Has anybody else had the problem? I have tried clearing the cache and disabling the prediction services, nothing seems to help. Many times it will just set there loading until I actually have to refresh or hit the homepage button again. I am using My yahoo as my homepage, I know- I know, and as I said above don't have this problem with IE or FF. Anybody have any suggestions, I really like chrome the best, but I have moved to FF just because my home page takes forever to load. Thanks in advance!"

+ - New "chemical internet" is able to compute chemical reactions

Submitted by daftna
daftna (630630) writes "Living on Earth has a story about a chemist who has made software to map the almost infinite number of possible chemical reactions: "Imagine a huge network, but instead of computers connected by nodes, we have molecules connected by reactions. And this information has been created not by me ... but by every chemist that ever lived." The network is a sort of a chemical search engine that has a new way of analyzing chemistry and finding optimal synthetic pathways out of the trillions of possibilities one would normally have to find by trial and error. Instead, "What we can do, having all the collective knowledge ever created in chemistry [is] train the computer to extract certain patterns automatically and these patterns are then based not on our individual experience but on the experiences of everything that was used to train the computer — meaning every single reaction ever performed." He calls it "Chematica" and details of the system are published in the journal Angewandte Chemie"

Once you got PDFs or JPGs you need to somehow organize them in a meaningful way: - by document date (a lot of extra work to add that)? - by type (could be done while scanning)? - by expiry date? - by sender/recipient ? OCR the content and make it conveniently available What system would do that?

I'll buy again. Heck I even would buy a give-two-get-one. The original machine had huge gaps between promise and delivery, but worked nicely reading blogs in bright sunlight. What I would wish for howerver is some documentation which batch my donated machine(s) would go to. I actually would be ready to chat with the receiver from time to time.

I used a number of devices with different sizes. The 2.3" mini Android phone up to a 10.1" tablet. My current favorite form factor is 7". It fits into a cargo pocket or a (inner) pocket of a jacket (even a suit, but I guess that's not your concern). I currently use a Huawei MediaPad. Solid unibody, great screen resolution. Runs Android 3.2 (unfortunately they haven't announced when they will upgrade to 4.0). Huawei leaves the UI in its original state, so you get pure Android bliss. Biggest let-down: you have a separate charger, it won't charge through USB, so you need to carry an adapter. It is slimmer than the Samsung 7"
