Benq 3d Projector MX525 with Sony HT Blu-ray E3200 - Watching Avatar 3D & Titanic 3D

My idea of watching movies has always been on a big gigantic screen ever since my childhood. I cherish the 3d movies watched on the silver screen theatres starting right from the vintage Chota Chetan till the recent Avengers End Game! 

My setup details

With the pandemic striking in 2020 it has become a distant dream to watch these 3d movies again in theatres. Thankfully I have my Benq 3D projector MX525 to the rescue. My Benq 3D projector MX525 (Cost around Rs 30K) in combination with my Sony 3D Blu-ray home theatre BDV-E3200 (Cost 30K) creates the magic of the large theatre-like vision and the high fidelity sound output. The magic of the 3D is witnessed through the DLP 3D glasses from Hi-Shock/IT-Hub India(Cost Rs 2500 per pair). The 5x5 ft projector screen that I am using is from a company called Logic which cost me around 4K bought from SP road in Bangalore. The overall cost of the setup is about Rs 72,000/- 

A word about Avatar
The movie which brought 3D to the forefront is none other than James Camaron's Avatar. The theatres worldwide were equipped with capabilities to screen 3D films and the excitement among the film buffs was immense since this movie was coming from the director of the epic movie Titanic (1997). The story and screenplay of this film were exemplary as it was an expression about warning people about global warming. 3D and the brand James Cameron further catapulted the popularity of this film many folds. Arguably Avatar still remains as the best film ever shot with such depth and pop-out 3D ever used so creatively in a feature film. The film was a witness to technical brilliance and how Computer Graphics animation can be used to transform a film into a mega marvel saga.

A word about Titanic 3D

The film Titanic was originally not released in 1997 as the Technology to film 3D films was almost non-existent at that time. A 2012 3D re-release was created by re-mastering the original to 4K resolution and post-converting to stereoscopic 3D format. The Titanic 3D version took 60 weeks and $18 million to produce, including the 4K restoration. For the 3D release, Cameron opened up the Super 35 film and expanded the image of the film into a new aspect ratio, from 2.35:1 to 1.78:1, allowing the viewer to see more image on the top and bottom of the screen.

Some of the other 3D films in Blu-Ray format which I own are as below:

1. Avatar

2. Titanic

3. Avengers

4. Life of Pie

5. The Jungle Book

6. Journey into a mysterious Island

7. Gravity

I made a video about the same projector a few years back which is now the most viewed video on my channel with ~30K views.

Why is ifconfig command missing in Debian Linux?

The ifconfig command has been deprecated and thus missing by default on Debian Linux 10.

# ifconfig
-bash: ifconfig: command not found

The new and recommended alternative for examining a network configuration on Debian Linux is ip command. For example to use ip command to display a network configuration run the following:

# ip address

The above ip command can be abbreviated to:

# ip a

If you still prefer to use ifconfig as part of your daily sys admin routine, you can easily install it as part of the net-tools package.

Requirements

Privileged access to your Debian Linux system is required.

Guiding Principle of Architecture

 Guiding Principle of Architecture 

You don't start trying to build a car, you start by looking at the problem; wanting to get from A-B easier. 

The quickest way to do this is to slap some wheels to a board and make a basic skateboard, it helps you solve the problem quickly and satisfy your customer, after which you can iterate.

Apple Airpods Max for 60K !!🤯 How about getting 60 LEAF or BOAT indian h...

I know you folks were curious to know about my opinion about the new Apple Airpods Max which is priced insanely at Rs 59,900/- !! 

So I made this video reviewing 2 other cheapest Bluetooth headphones from pretty popular Indian brands LEAF and boAt so that you can make a judgement in terms of the value which you can get at such dirt-cheap prices in stark comparison with the Apple product positioning and the functional aspects of these headphones. The headphones which I have reviewed are very good for the price which you pay.

The only major drawback of the LEAF bass 2 headphones which I found was their noise isolation/seal issue where external world can hear the music which plays in your ears during practical usage. This is going to be surely a problem if you are using it in a quiet place with other people around you. Other than this for casual usage at home, these are pretty well-performing headphones for the price which they are being sold in the over the ears headphones category.

I loved them when I paired it with my Sony 4K TV using a 3rd party Bluetooth receiver. The range of the Bluetooth and the sound quality of the output was exceptionally good due to which I am mighty impressed with the LEAF brand. However, for some reason, they do not sound as good when paired with my iPhone.

Nevertheless, the LEAF headphones do a pretty good job overall.

You can buy atleast 50 headphones at a price of 1 Apple AirPods max 😎 which is insane pricing on the part of Apple. But I would like to reiterate that it’s unfair to compare Apple products with these products since Apple is trying to position its products in a different league altogether which is the elite luxury premium category.

Some of the key features of the Apple AirPods max include: 

• Transparency mode where you can fully hear the external world noise even after wearing the headphones similar to AirPods Pro.
• Noise cancellation proving complete isolation from external world noise such as plane, train crowd noise and so on.
• Spatial audio providing immersive home theatre like surround sound where audio can felt from all direction.
• Handoff feature to switch seamlessly between all Apple devices.

The LEAF Bass 2 headphones are available at a price of 1.5K on Amazon and through an offer from the Cred app, I purchased it from the http://leafstudios.in  by applying a coupon code there by getting a Rs 800 discount on the actual MRP of Rs 1899/-. 

You can buy the LEAF BASS 2 headphones from this flipkart link at a discounted price of Rs 1499/- only

Apple Watch Series 6 - I bought all the Apple products to experience the ecosystem

In this video, I talk about my Deepavali/Diwali purchase of the last product which I had to buy to complete the essentials loop of the Apple ecosystem. It was my first Apple Watch purchase. I also talk about its features and my shopping for the Apple watch experience in Bengaluru, India.

Here is the timeline of the video

0:00 Intro with Watch faces 2:35 Shopping in the store 5:27 Unboxing in the store 8:03 Unboxing at Home 10:19 The Apple Ecosystem 11:31 Features in brief

My first smartwatch was an Android wear which is now called the Wear OS from Motorola, It was called the Moto 360n 2nd Generation smartwatch which was released in September 2015. The 1st moto 360 1st generation was the first round shaped Android smartwatch that was ever released in September 2014. I had ordered it from the Flipkart shopping website for Rs 19,000 and made an unboxing, overview and an in-depth review of the smartwatch. I have left the links to these videos below which you can watch for nostalgia purposes. 😊

Watch my Youtube video for my in-depth review of the moto 360 2nd gen Android wear smartwatch. I loved its luxurious look and feel and it was a sure attention grabber with its then exclusive always-on display which was not featured in the earlier Apple watches.

My next smartwatch purchase was just about a year ago which was the Fossil Gen5 carlyle HR which was also a great watch with an AMOLED display. I costed around Rs 20,000/-bought from the Amazon. It's a great watch for an android user with the capability to answer calls over the watch as it too features a nice speaker similar to the apple watch. In fact, I was using the watch for a good 3 weeks with my iPhone 12 as well. The only thing missing was that I could not reply back to SMS or WhatsApp messages using the Fossil watch. The Fossil watch is a Wear OS 2.0 based smartwatch with a great Google Fit app for fitness tracking. I felt that the Google fit had some cool functionalities to auto-detect the type of exercises or workouts. Apple Watch since Watch OS 5 offers automatic workout detection and will remind you to turn on the workout app.

The Apple Watch was released on April 24th, 2015 and due to its innovative design and the great user experience, it became the world's best-selling wearable device. People loved the interchangeable bands and their versatile personality.

Perhaps the best reason for people to buy the Apple smartwatch is that it works so well with the iPhones and its exclusivity. It makes a screaming fashion statement announcing that you own an iPhone. iPhone being an aspirational luxury product, the Apple watch allows people to flaunt their prized possession without having to flash their iPhones 💁🏻.

However things are now changing and Apple, in general, is changing as a company. No one would have ever thought that the best selling budget iPhone in America would be the iPhone SE 2020. Apple now offers iPhones and Apple watches for every budget. You have the iPhone SE & the Apple Watch Series 3 which is the cheapest offering from Apple. For the folks with deep pockets, they do have the newly launched iPhone Pro Max and the Apple watch series 6. 

Just to be clear, I am talking about smartwatches and not a fitness band or a watch.

Going by the books, a smartwatch must provide you with features beyond fitness tracking like step tracking, heart rate reading, exercise enablers, and so on. An ideal smartwatch must provide you with features such as push notifications, the ability to reply to messages from various apps, and the ability to answer calls when your phone is slightly away from you.

Honestly, the ECG & the Blood O2/Oxygen sensors and the apps are the bells and whistles of the Apple watch series 6. The always-on display is a very important feature that differentiates the series 6 from its other variants. Its USP comes from the interconnectivity it offers with the Macbook Pro. A simple example would be that if you are wearing an unlocked Apple watch, you do not need to type in your password or use touch id on your Macbook Pro! That's a neat trick. 

The Apple watch series 6 features the faster S6 SoC as compared to the S5 chip used in series 5 and the Watch SE. 

The other lovely feature is the functionality of making or answering calls over the Apple watch. Its an extension of the Apple ecosystem concept to be able to accept calls from any of the Apple devices like the Macbook, iPad, iPhone or the Apple Watch. (Apple Homepod too! well, that's one Apple device that I haven't got my hands on)

The below watch faces are another great example of how the Apple Watch takes advantage of its ecosystem. It can fetch the memoji's from your iPhone or iPad and set them as animated watchfaces on your Apple watch.

Really impressed with the way the Apple watch has been packaged in these big boxes with separate boxes for the watch and the watch straps. The watch straps have been placed without any folding, unlike other watch brands. The best thing was that a spare watch strap has also been provided for the people who wear the watch on their right hand as well.

This watch face can fetch all your photos from the iCloud and display them randomly whenever you glance at your watch.

The charging dock clings magnetically onto the watch and has some cool docking watch faces showing the time with the battery percentage.

It uses machine learning to detect your menstrual cycles using its cycle tracking app for the ladies. The watch also uses machine learning to detect if you are washing your hands, your fitness and exercise trends. The watch offers sedentary reminders and motivates you to stand every 1 hour and to close the move rings to help you stay fit and stay motivated to workout.

The watch also has a cool handwash detection feature which will give you a nice countdown for 20 seconds. It uses machine learning to detect if you are washing your hands with soap or just giving it a quick rinse :)

The funny thing was that it asked me if I was washing my hands when I was using sanitizer as well!
