A Friend of mine and I had attempted something similar but in an indoor setting. The key problem we faced is that the compass will in the phone and positioning system. The way we overcame the orientation was by using the camera to combine the visual odometer data with the compass measurements. We also faced issues with the localisation as being indoor meant we had to rely on wifi location which was not very good. Again, the way we got over this was to use the visual odometry, and rely on users turning. https://github.com/chelseyong/Android-App-AR-Map-Navigation

First launch was aborted due to a helium leak in the cryogenic engine a week ago.

I know that my opinion is going to be unpopular but I strongly disagree with this move. I can understand not allowing facial recognition to be run in real time, or for instance to ban corporates from tracking me and using my face for advertisement data, but to ban the police seems extremely dumb. Facial recognition can be used to significantly cut down investigation times and costs and thus reduce the stress on police.

Out of curiosity, dynamic class loading seems like one of those things where you would need to embed an interpreter in the application itself. So how does one deal with such cases?

We were introduced to version control in our first year. The only problem was that till we started managing large code bases, most people found it very difficult to understand why we used Git in the first place.

Where I live (not USA) the bus company uses those same buses for other purposes through the day. So recharging them fast is very important.

Not all ayurvedic medicine require heavy metals. There are herbs like boswellia (now also an allopathic drug) that genuinely do what they are supposed to do. Ayurveda, prevented black death in India. Granted there is a lot of bs out there that gets passed of but there are parts that do work. Distilling these parts is important. I think the lack of quality control in eastern medicine is what has given it a bad name. Granted we don't have antibiotics or anti cancer drugs but there were surgical procedures like rhinoplasty that were successfully carried out. Of course any medicine that is 2000 years old is going to be nowhere near what modern medicine is because we have had 2000 years to evolve it. Reason why easterners set store by it is it provided a bit more protection than what the doctors of medieval Europe could do. 1000years is a long time and lots changes, sadly eastern medicine didn't.

Last I checked homeopathy was western. i think your bias towards eastern medicine would be better founded if you were to say faith healing rather than eastern. Within eastern medicine one also finds people who used early forms of experimentation to derive working cures. Examples of working medical cures include boswellia used to treat bursitis, artemisin used to treat malaria. Also both Chinese and Indians had developed anaesthetic before Europeans. Similarly the procedure of rhinoplasty was developed in India. When the British came in western surgeons studied the technique and took it back to Europe. In fact hygiene was a critical part of the ayurvedic surgeons life well before Europeans realized the importance of hygiene in surgery. Of course there are a lot bogus stuff in eastern cures as well but in the west you have stuff like homeopathy. I think the key take away is that you cannot divide by east and west. We are after all human and each culture has their own contribution to the face of the earth.

They work well, just that you need a lot of patience (and know how) to work with them. Also GPUs are expensive. By the time you realize that you messed up you have wasted a lot of time. Of course this is true with any ml algorithm out there. But what I'm trying to say is it is possible that an as yet unknown method exists that may be less computationally complex.

One of the problems I see is that people abuse deep neural networks no end. One doesn't need to train a deep nn for recognizing structured objects like a coke can in a fridge. Simple hog/sift/other feature engineering may be a faster and better bet for small-scale object recognition. However expecting sift to out perform a deep neural net on imagenet is out of question. Thus when it comes to deploying systems in a short frame of time one should keep an open mind.

TF is not the nicest thing to work with. It is still very computationally expensive to use on embedded hardware platforms.

Singapore is 75% chinese, 15% malay and 10% Indian. Most malays and indians DO NOT speak chinese and are as successful as chinese. In fact many Chinese in singapore do not speak Chinese or speak better english than chinese. Furthermore the variety of dialect groups of Chinese in Singapore is so large that learning mandarin will not necessarily help you communicate with the older population. Its better to know a bit of every one of the languages than know only one very wellto get by. If you're thinking of singlish while words like "kena" come from chinese dialects (not mandarin), others such as "alamak" come from other languages such as malay.

It has more to do with economic need than culture. As you see Asia has grown on a manufacturing based economy, whether it is Singapore or China. Despite being such a small country it is surprising to see what all we produce in singapore. In a manufacturing economy you used to need Human capital that is just hardworking, thus quantity over quality. However now that things are becoming expensive and automation has taken over reform is necessary. The job market is shifting toward private enterpreuneurship where people have to be creative to solve problems. One needs to start placing more emphasis on designing/researching/innovating than manufacturing. That is why the education reforms are necessary as in these fields it is quality over quantity.

Do take note though that in both Singapore's and India's case the system of examinations has been based on the British colonial system NOT something that was imbibed into asian culture.

Although the Chinese had civil service exams since ancient times, by the early 1900s there were more ways to make it as a rich businessman rather than study for the civil service examinations.
