Periscope: A scope for amateur journalists

Every human being has this basic instinct to share information with his or her peers and sometimes with the entire globe. In earlier times, news was primarily spread by the word of mouth, then came the idea of using human messengers, sending letters or scrolls via trained birds or other pets, which then evolved into the concept of printing newspapers and finally all of this led to the creation of the most popular and preferred form of journalism, called Broadcast journalism.

Broadcast journalism, as defined by Wikipedia is the field of news and journals which are “broadcast”, that is, published by electrical methods, instead of the older methods, such as printed newspapers and posters. Broadcast methods include radio (via air, cable, and Internet), television (via air, cable, and Internet), and, especially recently, the World Wide Web. Such media disperse pictures (static and moving), visual text and/or sounds. Today there are several thousand news channels in all the developed and developing nations like the USA, UK, EU nation’s, Russia, China, India, Australia and Japan.

In the past two three years or so, the concept of professional and especially amateur online journalism has evolved a lot. Thanks to the internet, the common man has all the necessary platform to start his/her own website or blog or YouTube channel to showcase his/her talents. Now, speaking of online journalism, about a year ago twitter decided why not build a free platform to enable everyone with a smartphone to live stream their surroundings through their own perspective. And voila Periscope was born with an apt tag line:

"Explore the world with someone else’s eye"

It has a similar relationship with twitter like what Google+ has with Google, to the extent that all twitter accounts have a periscope account that is waiting to be enabled by its holder/owner. Now looking at the periscope app, it has a very decent UI (user interface) and is loaded with umpty number of features. One can stream live videos of their surroundings, search for streaming’s of other users, like or comment on the video of other users and also follow other users whom’s content catches their eye. I downloaded the app about a month ago and this is what was waiting for me:









I personally think that this app is pretty great with a very neat UI and my overall experience on this app was pretty satisfactory. It allows me to live stream the interesting things and events that happen around me. The only problem is that; for streaming videos, a pretty strong internet connection is needed and if you are in a country like India where there is no fast public WiFi or no public WiFi at all, this could pose as a major setback. But looking on the bright side, all of us can stream the cool things that surround us on several occasions and also view the cool things that surround many others around the globe, at the comfort of our couch or office chair or a park bench.

Castle season 08: Rising to its earlier pedestal



Nathan Fillion and Stana Katic 

Castle is a television series that is being aired on ABC since 2010. It stars Nathan Fillion and Stana Katic among others. The main plot of the show is about the day to day interactions between a bored fiction writer Richard Castle (Nathan Fillion) and  a successful female cop Kate Becket (Stana Katic). The story line is mix of action, comedy, drama and action with one or two episodes of sci-fi. The first season had only 10 episodes and after witnessing a great response from the audience, the successive seasons had either 23 or 24 episodes.

The show's rating grew day by day as the seasons progressed. The plot was getting thicker and so did the loyalty of the viewers. Despite having a unique theme the story-line of the episodes became rather stereotypical (or predictable) in the sense that, the first two episodes of a season showed the main plot and the other 19 or so episodes were rather fillers (but interesting nonetheless) and finally, the plot either continued or ended in the last two-three episodes of the season. This was the case for most of the seasons.

Now coming back to the topic in hand, season six of "Castle" ends with Castle going missing on the day of his wedding with Kate. As a result, there was a lot of anticipation as to how the story was going to progress and the number of viewers grew by the million. In accordance with everyone's expectations the next season (season 7) started with the man hunt for Castle and a major plot in the twist. And as usual the main plot was buffed after the first two episodes and was carried forward to the last two episodes of the season. Almost all the viewers including myself, patiently waited for the season finale. But to everyone's disappointment the story-line was ended in a rather bland manner much before the finale and the final episodes were just mere fillers (much like the rest of the episodes in that season) to end the season. This caused a large downfall in the number of viewers, but not that large a downfall to cancel the show. Personally, even I didn't watch the last two episodes of season 7 until about seven episodes of season 8 had aired.

After a few months from the airing of the finale of season 7, the trailer for the next season was released on YouTube and apart from the hardcore "Castle" fans, the others were quite skeptical. To say the truth, despite being a hardcore fan myself, even I was a bit skeptical about it! Then on September 21, 2015 the first episode of "Castle" season 8 aired on ABC and I have to say that it was pretty good when compared to the season finale of season 7. The plot is solid, the story line is pacy and gripping and on the whole, I would say that "Castle" is gaining back its popularity and it is definitely rising to its earlier pedestal.

Bladeless Wind Turbine

Energy created by conventional three-blade wind turbines is cheap, sustainable and pollution-free. But according to current estimates, the devices' fast-moving blades kill up to 300,000 birds annually in the U.S. and roughly similar numbers in other parts of the globe.
That could change with a bladeless wind converter called Saphonian, designed by Tunisian engineer Anis Aouni. He studied ancient sailboats and the movements of birds and fish to develop a parabolic dish that rotates in a peculiar pattern while catching the wind like a ship’s sail.
Saphonian-Bladeless-Wind-Converter
It's like a big 'eight' in space,it's a movement that we can find in nature. We find the same movement in fish tails when they are moving, or in birds' wings.The bladeless converter creates less noise than traditional wind turbines and does not suffer from the gyroscopic effect, which makes it easier to adjust to changes in wind direction. The prototype is a little more than 1 meter in diameter, but computer models show it is scalable to bigger sizes.
Aouni hopes it eventually will be able to turn 80 percent of wind energy into electricity. “In practice, we reached 1.7 times the performance of a traditional wind turbine," he said. "Economically, it is a machine that costs much less than an equivalent wind turbine.”
Tunisian company Saphon Energy, which developed the prototype, has won several awards for the new turbine, including support from Microsoft’s initiative to help African startup companies. I sincerely hope that this prototype is put into actual use.
The given link contains the video depicting the working of the actual prototype.

Lifi: Internet using light

Imagine using your car headlights to transmit data or surfing the web safely on a plane, tethered only by a line of sight. Yes. You read it correctly, Professor Harald Hass has developed a new prototype that uses just three components to justify his claim: a LED light, a solar panel and a display device/screen.

To further cement your trust into this article, here is a small intro about the man under the spotlight: Professor Haas received the PhD degree from the University of Edinburgh in 2001. He currently holds the Chair of Mobile Communications at the University of Edinburgh, and is co-founder and Chief Scientific Officer of pureLiFi Ltd as well as the Director of the LiFi Research and Development Center at the University of Edinburgh. His main research interests are in optical wireless communications, hybrid optical wireless and RF communications, spatial modulation, and interference coordination in wireless networks.
Now back to his device, a solar cell is a device that converts incident light into electricity. When the incident intensity or brightness of the light is varied, the output current also varies accordingly. Hass has devised his prototype using the same principle. The intensity of the light is varied very rapidly, almost unnoticeable to the human eye and that signal is converted into the video that is to displayed by the screen or a laptop or any computer device. The data transfer rate of this device is believed to be fifty megabytes per second, which much higher than the data transfer rates that is currently provided by our broadband connections.
Hass initially used specially fabricated photo-detectors to enable this process, later he switched to solar cells to utilize the current infrastructure to its utmost potential. The device is completely eco-friendly and can be manufactured with no further increase in energy consumption than the present levels. Hass and his team believe that they can positively launch this project in a global scale in the next two to three years.
Hass first presented his device at a TED event, its link is provided below:

Which fitness tracker should you buy?

       They are leading the charge of the wearables. No, not smartwatches, as many had predicted, but the much simpler smartbands. Ranging from straps with small core units to calculate the distance travelled, to the more complex watch-like designs that replicate some of the functionality of smartwatches, smartbands are rapidly becoming popular—not just among fitness enthusiasts but also among those who aren’t tech-savvy. But as in most things technology, smartbands come in many varieties, ranging from the utterly basic to smartwatch-like devices, and different price points.So which one should you be opting for?  I found the answer to this question by answer the following questions that I found on a web site. Choose your most apt answer choice and add the points accordingly to get your final score, based on which you can select from any of the devices given below (after the questionnaire). 
1. Will you be wearing anything else (such as a watch) besides the band on the wrist?
a. Yes. The band should blend in or be invisible.
b. Yes, but it doesn’t matter because I like wearing accessories.
c. No, this is going to be the sole, or at least the main, adornment on my wrist.
A: 2 points; B: 3 points; C: 5 points
2. How interested are you in getting information about your fitness levels and what kind of information will you seek?
a. I’m just starting to keep an eye on it, so basic information, mainly—steps taken, calories burnt and the like.
b. I’m getting serious about my fitness, so I will need more information and a detailed analysis.
c. I’m a fitness fanatic. I need extremely detailed information, including monitoring the heart rate, and perhaps even a fitness expert guide me.
A: 2 points; B: 3 points; C: 5 points
3. Do you want a gadget dedicated to just fitness or one that has “smart” features too—such as the ability to alert you about phone calls, text messages, mails and the like on the wrist?
a. I want as much “smartness” on the band as possible—if possible, enough to ensure that I can leave my smartphone in my pocket.
b. I would expect a certain level of “smartness” in the band, such as calls, text and mail alerts. Alarms would be a must.
c. It would be handy if the band had “smart” features but their absence would not be a deal-breaker.
A: 5 points; B: 3 points; C: 2 points
4. Would you prefer seeing fitness information on your phone/computer or on the band itself?
a. I would definitely want to see information on it—what is the point of my buying a smart device for fitness if I still have to pull a phone out to get information?
b. Having the option to see some information on the band would be a good thing; pulling out the phone repeatedly can be a bit of a pain.
c. I don’t mind seeing it on the phone or PC, as I use these often in any case.
A: 5 points; B: 3 points; C: 2 points
5. What kind of activities do you want it to track?
a. Basically, distance travelled. Anything additional (steps climbed, etc.) would be a bonus.
b. Track everything in as much detail as possible. It should even tell me where I was walking or running—tracking as many types of exercises as possible is a must, as well as activities like cycling and hiking.
c. Distance travelled, steps climbed and, if possible, basic exercises like push-ups and sit-ups.
A: 5 points; B: 2 points; C: 3 points
6. What is the level of accuracy that you expect from your smartband?
a. No one wants an error-prone device, but I understand there can be the odd deviation, so yes, I could live with a good approximation.
b. I would prefer it to be reasonably accurate—this is about fitness, after all.
c. I demand absolute accuracy. If possible, it should also have GPS to track my runs and not rely just on movement.
A: 2 points; B: 3 points; C: 5 points
7. In terms of battery life, what are your expectations?
a. I would prefer it to last as long as possible. I do not want to keep worrying about charging it.
b. As long as I get the information I want, I don’t mind recharging it frequently—after all, don’t I do the same with my phone?
c. As I want a fair bit of information, I can understand that I may have to charge the device regularly, but I would still prefer one that needs to be charged at the most once or twice a week.
A: 2 points; B: 5 points; C: 3 points
8. Finally, how much would you like to spend?
a. Well, the lower the better, as I am just starting out, but I could go up to Rs.5,000.
b. I would say, up to Rs.15,000—I am getting serious about fitness.
c. Budget is not an issue really as long as I get a device which delivers.
A: 2 points; B: 3 points; C: 5 points
SCORINGAward yourself points based on the response to each question, in accordance with the scoring pattern mentioned individually
16-23 points


You are not really looking for something too complex, so a basic fitness band like Xiaomi’s simple Mi Band (Rs.999 at Mi.com) or the Fitbit Flex (Rs. 6,990; Amazon.in) would be just what you need for your requirements.
24-31 points
You are just beginning to get serious about fitness, so our advice would be something on the lines of the Garmin vívosmart (Rs.10,990; Snapdeal.com) or the Jawbone UP3 (Rs.14,999; Amazon.in), which deliver more detailed information about your fitness than the “base” devices.
32-40 points
You are pretty much in “fitness freak” mode and have a geeky side as well, wanting to cram as much on to your wrist as possible. You would like something on the lines of the Fitbit Surge (Rs.19,990; Amazon.in) or even one of the more fitness-oriented smartwatches with GPS and a heartbeat sensor—such as the TomTom Multi-Sport Cardio watch (Rs. 23,499; Flipkart.com), any Android Wear watch that runs the Google Fit app, or even the Garmin fenix 3 (Rs.49,990 onwards) if you are rich enough. Even the updated GOQii band would be a good option, because it is essentially a subscription service that gets a human fitness coach to monitor your exercise and diet regime, and suggest changes and improvements regularly.

Moto X Play

       The Moto X Play was launched by the mobile manufacturing giant Motorola on the 2nd of September,2015. Initially before the phone's release, there was a huge speculation about this phone's pricing range, whether it would be in the price range on the G-series or the X-series. But surprisingly, the phone's basic variant was priced at 18,499 INR which was in-between the price ranges of the G and X series.

       The phone was met with a huge welcome as the previous moto phone's namely the moto G (I gen), moto X (I gen), moto turbo, were a huge success. The main selling point of this phone was the amazing battery life and its industrial build quality. The main specs of the phone are the 3630 mAh battery, 21 MP rear camera coupled with a 5 MP selfie camera, a 5.5" full HD display, a 1 GB/ 2 GB RAM (depending on the variant), Pure Android OS experience and a water-repellent coating. The base model is priced at 18,499 INR and the top model is priced at 19,999 INR.

       Two months ago, I bought the 19,999 INR variant via flipkart and I have to say, the phone lives up to my expectations. On the plus side the display is sharp and crisp with great viewing angles, the phone rarely lags, the phone heats up after an hour of continuous usage, but also cools down pretty quickly for a device with an enclosed battery. On the minus side the camera quality is not that great for a 21 MP camera. Personally for me, the major setback is the battery life, motorola advertised a 30hr mixed battery life whereas, I am only getting a 16 hr batter life on mixed usage (facebook, whatsapp, youtube, music, instagram, twitter, google newstand, cricbuzz and clash of clans). On the whole, the phone is a workhorse and lives up to its hype. And for a light price tag of 18,499 INR, I think its more than a fair deal.
