UK Spectrum Scale User Group Meeting - 2019

Related image

Intro
The UK/World Wide 2019 Spectrum Scale User Group took place on the 8th and 9th May at the IBM’s South Bank Client Centre. I had the pleasure of attending this meeting alongside two colleagues from our office. The first day  hosted talks from the Spectrum Scale CTO who presented an interesting history of GPFS from its inception to the current status.

Networking
The key benefit that I personally got from attending the user group meeting was the networking. We are looking into a implementing Spectrum Archive solution and getting into contact with people who have practical experience with this offering was key. I was able to have a good discussion with Khanh Ngo, who the the IBM STSM responsible for Archive. He gave me his contact details and allowed me direct access to contact him whenever I want something pertaining the his product offering. He presented his product on the second day of the conference, and his presentation was top-level but concise. We discuss about my rough design sketch and we ended with him offering to drop by our office the next time he is returning to Europe, and that around Aug when he is coming to Amsterdam.

The next person I was pleased to meet was Dan Foster, who happen to be my predecessor. Dan has done some dev implementations of both TSM-HSM and LTFS-HSM, so he quite knowledgeable on these product offerings. The key issues with Archive, that Dan pointed out to me are the Reclamation and Reconciliation. While the Archive had baseline functions to perform these tasks, an admin with need to know, in a verifiable way, the actual tapes that/files that will be involved in these processes. This requires some scripting on top of the base functions provided by Archive, is automation has to be implemented. Dan himself has a product that provides this functionality and more, offered by his organisation.

The other key person I got in contact with, wrt to the above project, was Patrick Dekkers, who is a Storage Specialist at Amsterdam UMC Locactie VUmc. Patrick has implemented the Archive for his organisation. His is a Stretched-Cluster configuration and he gave a presentation of his overall storage infrastructure, which was helpful to understand how they are using Spectrum Scale and Archive. It would be a good think to keep in contact with Patrick to exchange notes on our experiences, and probably a working visit to his facility to catch-up and see stuff in action.

Other observations
Two technical presentations by the Spectrum Scale developers were quite interesting for me. The first was titled "Deep-dive on Spectrum Scale Reliability, Availability and Serviceability improvements". The talk centred on network reliability, outlining cases, causes and troubleshooting of network related issued in Spectrum Scale. Key was the improvements in v5.0.2 that make log messages more clearer. Having implemented Spectrum Scale Object Storage a few weeks ago, I was quite happy to see the commands I have gotten accustomed to, accompanied by easy to read messaged, and enhanced context as provided by the developer on the day.

The other presentation that I found interesting was the "Overview: Spectrum Scale support for NFS and SMB
Spectrum Scale Best Practices for Snapshots" The bit about Snapshot best practices was interesting. I realised that there is actually a careful consideration that has to be taken designed processes for snapshotting and backup. My hunch was that most of the time people use badly designed processes, which just work mainly because the systems are not performance constrained, or end applications (and or users) are tolerant of the effects caused by bad practices. One key think I was reminded is that even with Fileset Snapshot, the cluster run a filesystem-wide quiesce which means taking and deleting of a large number of filesystems can result in a big impact even without end-user I/O. The choice and time for deleting snapshot has to be carefully considered.

Lighter notes
Overall I enjoyed my 2 days in London with a first day rendezvous at the Jazz Cafe were Hypnotic Monkeys produced a superb performance. I especially like their Afro-Jazz sounds garnished by Rap lyrics. Also the days coincided with UEFA semifinals which we enjoyed in the local pub which were often full to the hilt.
Being my first ever user group meeting, I was thorough impressed with the level of organisation and attendance. Meeting the developers, most of whom I had seen their names in user group forums/mailing lists, that was refreshing to put faces to names.

Huawei Mate20 Pro - A great spec'ed flagship!



I received this product as part of a review program in return for an unbiased review
The Huawei Mate20 Pro smartphone is essentially, according to me, a phablet if we are to go by the screen size. But let's face it, size really matters! I do not want to squint my eyes when i am watching videos on Youtube and Video Hub or other “tubes” and “hubs”. Screen real-estate is a critical factor, as the trends have proved. The Mate20 Pro’s screen is "Yuuuuge" at 6.39 inches, whilst the phone weighs only 189 grams and is 8.6mm thin. This is probably the best screen size to weight ratio I have seen. Moreso, the phone fits snuggly into one's' hand allowing one hand operation without any problem, thanks to the much reduced width of only 72.6mm, slimmer than even the P20 Pro. The key feature here is the edge-to-edge screen, which monopolises the phone's real estate. You will probably instantly notice the "top notch" (pun or no pun, you decide). The notch can be turned off if one doesn't fancy it.




There is no home button on the front, like on the P20 Pro, instead, the fingerprint scanner comes embedded into the screen. Like most modern smartphones the Mate20 Pro ditches the home button so as to dedicate the front, to the screen. Other interface features of note are the screen recording, which allows one to record all screen interactions, and the split screen, which allows two applications to be run on separate screens simultaneously. This seems to be a standard feature for most Huawei phones now

The battery on the Mate20 Pro is a humongous 4200mAh, thats 200mAh more than the already juice-saving record breaking P20 Pro. This means the Mate20 Pro will be able to keep things ticking for 2 days easy-peasy, after a full charge. I managed a whole 3 days uptime despite my intensive use of the camera as I was testing various modes and scenarios during the same period. Couple this with the quick-charge feature, you realise that you soon forget about the yesteryear wores of cellphone charging.

Like its predecessor, this phone is all about the camera. The phone has got 3 rear Leica cameras which work together to provide appropriate lighting, depth, focus and colour performance. Indeed the power of AI is summoned on this phone to aid in object auto detection, auto camera mode sand settings accordingly, making this behemoth, a perfect point and shoot buddy.

The Mate20 Pro has all other bells and whistles that one would expect from Huawei’s flagship. It's all IP68, IR sensor is versus, NFC etc etc. but this phone has its shortcomings like all things “many-made” and man-made. The in-display fingerprint sensor is sometimes inconsistent, failing to recognise my fingerprint, meaning i have to use other authentication modes. Also if one uses a tempered glass screen protector, this problem can be made worse. This technology could be in its early stages and one hopes this will improve with time.

However, the Mate20 Pro comes with all PIN, Fingerprint and 3D face recognition mechanisms, this allows one to choose the methods they feel is most effective considering their circumstances.

HP Sprocket Plus: An ultra portable photo printer showcasing the future!

The HP Sprocket Plus, is an ultra portable device, that is showcasing what the future of photo printing is like. The technology is very sound and the pictures are convincing.

The Sprocket Plus has external dimensions of 141.9 x 89 x 18 mm (5.59 x 3.50 x 0.71 in) and weighs only 0.205 kg (0.45 lb). It can print photos of size; 2.3" x 3.4", which is 30% larger than the standard Sprocket.

Setting it up is a breeze,and its operation is straightforward, with the Sprocket App that is available on both Android and iOS. It is enough to know that you can take a photo on you phone and make a couple of presses to print that photo to the sprocket.

Mine came with 20 Photo paper and 10 sticky-backed photo sheets. The sticky-backed sheets are a fun addition to this device. It means you can now be able to print your own stickers, yes, that's right, stickers. The size is not big enough for framed photos, but not small enough for kids stickers, so I will call these “Adult stickers”. Fun uses for these stickers could be DIY postcards, wallet stickers, luggage stickers and memoir or travel book photos. For the creative types, this can be a very useful feature, making the Sprocket Plus a fun, ultra portable , social and creative gismo.



Sticky-backed paper (pack of 10)

I know some may have questions about the quality of the photos, so I will say my opinion so that you may be guided. These photos are nothing near the quality of professional photos printed on photographic paper. But as a guide, the quality is comparable to 1990’s film-based camera photos which were commonly printed on Kodak paper. Some of you may still have such photos in your drawers, so you should rest assured you will get something similar from this device.

This device does not require cartridges, and for that reason, I will say the price for it (retailing around £160) is not bad at all. I am yet to get authoritative information on the durability of this device, but a 2 year warranty will be enough for such a device.

Having said all this, I expect HP and other Tech companies in this niche, to take this technology further, to bring newer models that are capable of printing bigger photos, with much improved quality.

Huawei Flagship: P20 Pro - The Super Crafted AI Laced Behemoth

"Probably the best Android Smartphone out there!" - me

I received this product as part of a review program in return for an unbiased review

I am talking about the Huawei P20 Pro Smartphone. This is Huawei flagship phone, which is mearnt to compete with the likes of Samsung Galaxy S9 and Apple's iPhone X (or 10 if you like). I have beena able to play around with this beauty and boy oh boy, I fell in love!

The P20 Pro is a smartphone which is supposed to be in the category of so called phablets, if we are to go by the screen size. I say "supposed" because the moment you get hold of this phone, you will realise how its profile is deceptive. The screen is "Yuuuuge" at 6.1 inches, whilst the phone weighs only 180 grams and is 7.8mm thin. Moreso, the phone fits snugly into ones' hand allowing one hand operation without any problem, thanks to the reduced width of only 73.9mm. The key feature here is the edge-to-edge screen, which monopolises the phone's real estate. You will probably instantly notice the "top notch" (pun intended), reminding you of the iPhone X's notch, except that Huawei's was done much better, leaving useful screen space (for status icons) either side of the notch. Also the notch can be turned off to leave just a rectangular screen. You may want to berate Huwei for "copying" here, go ahead, I totally understand (but who doesn't)

I will not bore you with specs, which can be found in  full, on Huawe's website via THIS LINK.  This phone is all about its camera, but I will appetise you with other features before I give you my 2  cents about the camera, and my thoughts on what the camera AI direction can produce, in next-gen smartphones.

Interaction
The home button is very much present on the front bottom, for those like me, who like the button style for tactile control. Th button also holds the fingerprint scanner, which is where I prefer it to be, than at the back of the phone. Other phones may have ditched the home button so as to dedicate the front space, to the screen, but Huawei did it in a very effective way, that doesn't take much screen space, by using a very slim button. Other interface features of note are the screen recording, which allows one to record all screen interactions. This is especially important if one is creating usage manual or tutorials for apps etc. There is also the split screen feature, which allows two applications to be run on separate screens simultaneously. This seems to be a standard feature for most Huawei phones now.



Battery
The battery on the Pro 20 is a decent size 4000mAH, which for me has been able to keep the juices flowing for  almost 2 days after every full charge. This was despite my intensive use of the camera as I was testing various camera modes and scenarios during the same testing period. If you couple this with the quick-charge feature, you realise that you soon forget about the yesteryear wores of cellphone charging, especially if one is making use of portable power banks.

IR Remote
This phone comes with an InfraRed (IR) LED. This means that you can be able to control about any IR device like TVs, Radios, Set-top boxes etc. I have used an app called SURE Universal Remote on Android for over 5 years and it works perfect on this phone.



Camera and AI
Now, this phone is all about the camera, so my camera highlights deserve to be mentioned here. The phone has got 3 cameras which work together to provide appropriate lighting, depth, focus and colour performance. More detail on how this is achieved, can be found on Huawei’s website, but the more critical ingredient in this recipe is the Artificial Intelligence (AI) processing. Indeed the power of AI on this phone is evident through the camera. The camera is able to detect objects and adjust the camera mode and settings according. One good example, which I noticed immediately, was how colours were being enhanced whenever I was capturing photos of food at restaurants (one of my favourite hobbies) In my experience the AI has been able to provide the touted “Point and shoot perfection” in Huawei’s speak.




Starting with the Huawei PSmart, the front facing cameras have been using beautifying algorithms that make selfies very flattering. I have used beauty selfie features on Samsung phones, but I have to say Huawei's algorithms are probably the best I have seen so far. On Samsung, the processing seemed excessive that all the blemishes where being removed, leaving a face that looked like it had had a heavy application of make-up. On one instance, my friend had to ask me if I was now wearing make-up. With the P20 Pro, the skin tone is smoothed out without excessively taking out detail, which leaves selfies more beautiful while preserving natural features.

Possibilities with AI driven camera
Imagine capturing a photo of your friend John, and the phone aromatically save the photo with the filename "John" and tagging location and weather details at the same time. AI with the camera can be useful in various ways. Software can b developed that regularly capture the self of the user, records various health metrics and be "aware" of surroundings via AI object recognition algorithms. this can be exploited to monitor health and wellbeing of elderly or disabled people. Augmented reality is another easier way of exploiting AI camera features, but that has already been demonstrated in many smartphone applications available today. An extension to that, will be turning the phone into a real companion. Using smart speaker AI, like Alexa, together with Camera AI like on this phone, A smartphone can be turned into a companion for a blind person, who strap the phone on their neck, speak to it, and the camera continually sensing objects around and providing audio warnings and instructions via smart speaker, to guide the blind person around a place like a public square.
There are probably other use cases which we may not comprehend now, but which I am sure are already in the pipeline, that's how technology has always been.

Cons
It would be blasphemous to claim that Huawei has come up with the holy grail of a phone. The P20 Pro has its shortcomings, but like all things, those may actually be someone’s meat. Mine came  with 128GB internal storage and that cannot be extended because there is no microSD card slot. For me, that capacity, plus my cloud storage facilities, means the storage is much more than what I need. Secondly, the 4K video capturing is not stabilised, so if one want to do some serious 4K videos, they may want serious gear like gimbals for a smoother output. However, for most personal video requirements, the full HD 1080p is adequate. Lastly, there is no headphone jack, so if like me you were still using those wired earphones, you are out of luck. Fortunately for me i had Bluetooth earphones as well, which i had not been using, but turned out they are actually better quality than the one i had been using. Only thing i hate it having to charge the earphones everyday

Verdict
Not perfect, but still probably the best Android smartphone on the market currently...

A Budget Android Smartphone Punching Above its Waist

A Great Value for Money, Mid-range Android Smartphone

I received this product as part of a review program in return for an unbiased review


First Impressions:
The Huawei P Smart smartphone is probably one of the nicest looking mid-range android smartphones around. Mine came in black, but immediately I was drawn to its sleek looks and feel. The phone is slim (see detailed specs here) and packs a screen that covers a satisfying amount of the phone's real estate. The placement of ordinary features like speakers, cameras and headphone jack, are nothing out of the ordinary. This means that the phone will provide a seamless experience to most of the popular phones that we have now been accustomed to. The profile and curved edges makes it look and feel like one of the most popular brands, so nothing new there, and if you had loved some of these already popularly available phones then you will love this one. New to me is the fingerprint scanner at the back and also you will notice the 2 cameras there as well.


Judging by its cover:
The looks are quite suave. I like the thinness. the screen is bright, and big. The phone's slim width profile makes it snag in the hand. Branding is spot-on, so for these reasons, I would quickly judge this to be the "best value" android phone. Obviously its durability, reliability and functionality are not being judged in this statement.



Innards and gonads:
Screen
The phone boasts of a 5.65 inch TFT screen made of 2.5D toughened glass. It packs 468 pixels per inch, making its pixel density, average, although not top of the available range. Perceptively, the colours are very vivid and bright giving an impression that the screen quality s top quality.
Operationally, the P Smart is allows a split-screen, meaning you can run 2 separate app/tasks in two separate windows at the same time. You may be familiar with this from Samsung’s modern Galaxy Note range. Although the screen width is slimmer, the bezel is very minimal, giving an edge-to-edge screen look, hence why it was possible to have a big screen, while maintaining a slimmer look and lightweight.

Audio and video
The is a 3.5 standard headphone jack, so no surprises like those one pulled by Apple. The is a loudspeaker at the bottom edge and an earpiece at the centre top just like the iPhone 6 range. Volume buttons are on the right edge where there is the power button, just like Samsung Galaxy phones, everything is standard as far as these are concerned. The sound quality is decent and video quality is full HD.

Camera
The P Smart has 13MP dual cameras at the rear, and a 8MP front camera. The dual camera at the back allows shallow depth images to focus properly. Larger aperture lenses makes photos very accurate in terms of lighting and also capturing the real colours. Swiping left when using the camera, brings up the settings and most of the modern setting's like GPS tagging, voice control, etc. are present. The front camera comes with a very useful feature called Smart Beauty, which makes selfies stand out.

Hardware and performance
The one I received came with 32GB internal storage, but there is an MicroSD card slot which takes upto 256GB sd cards. Next to this sd card slot, is the nano sim slot and the phone comes sim-free.
The phone boasts of an Octacore processor and 3GB RAM which keeps everything ticking nicely and smoothly. Latest Android 8 operates all these inards and provides that popular OS feel that we have all grown to love.
The 3000mAh (probably now the standard) makes sure that you get a good solid 20hr talk time from your phone. Obviously when you install some power hungry apps, your battery juice may drain much more rapidly, but you are assured that you will be fine for at least your average working day period.

Network
Obviously this beauty is 4G ready and all other usuals are versus, like WiFi b/g/n, Bluetooth, NFC and GPS. Sensors available are the fingerprint scanner, compass, gravity, proximity, ambient light sensors.

USPs and Appeal
I am giving a summary of features which I feel stand-out for this device, especially when compared to other phones in the same price range.

Smart beauty
For me, this feature takes the trophy. I have used beauty selfie features on Samsung phones, but I have to say this one is probably the best I have seen so far. On Samsung, the processing seemed excessive that all the blemishes where being removed, leaving a face that looked like it had had a heavy application of make-up. On one instance, my friend had to ask me if I was now wearing make-up. With the Psmart, the skin tone is smoothed out without excessively taking out detail, which leaves selfies more beautiful while preserving natural features.

Dual Bluetooth
This feature allows the phone to maintain and manage 2 Bluetooth connections simultaneously. This, for me, means I am able to connect BOTH of the in-ear Bluetooth earphones, In-ear BT earphones that come without any cable are very popular nowadays because they are very small and are not noticeable, allowing one to wear them without anyone noticing. However, most, only one can be connected with most phone, so you would only be able to use one at a time. Now with the P smart, one is able to connect 2 of such earphones and enjoy an immersive audio experience.

Split screen
This feature is common with the Samsung Galaxy Note range, where you can have two windows on your phone with each widow doing a different task, like playing a video in one, whilst beside it having a Chat with a friend or browsing the web. Just like with the Galaxy note, not all apps would be compatible with this, but this had been a very welcome feature in the past for me, something I have missed whenever I had to use any other phone. Now its available with this “budget” phone, how nice!


Split-screen (2 windows; gmail and facebook)

There are also other features that one would find interesting, like use of hand gestures to take photos (handsfree capture), speed sharing, where you can send files without having to pair phones and also without need for internet, and also use of the fingerprint scanner as a shutter button, as a trackpad for navigation and as a wake button.

When all is said and done:
This phone will be ultimately be judged on the basis of what it offers, vs its price. For that reason, I would say the phone is priced right, currently available at some retailers at the price sub £200. That's a good balance between performance, brand reputation and price. Its worth every penny.

New Samsung Gear 360 and Gear VR headset

Intro 
This post is seeks to review 2 Samsung devices namely the new Gear 360 (2017) and Gear VR headset. You will notice that I have previously reviewed the earlier Gear 360 version on this blog, so this post will primarily talk about the new model in a comparative manner. If one want to see the specs and capabilities of the old model, please see my previous review on this link


New Gear 360 
The new Gear 360 camera is an awesome and well made product. It keeps the best parts of the previous model, vis-a-vi, stylish aesthetics, a sturdy construction and indeed being easy on the eye. with its beautiful colours, especially the white version. This new camera is about 40% smaller than the previous model, with a few modifications to the position of the small display, which is now on the integrated handle. No more separate tiny tripod handle. Setting it up is a breeze, quite straight-forward even without reading the instructions lol! (even though I always read first). No differences to the previous model.

    *Android 5.0 or later
    * iPhone 7, 7 Plus, 6s, 6s Plus, SE  with iOS 10.0 or later

Of particular importance, you will realise that this new model is compatible with almost all modern phones. For me, I wanted compatibility with the iPhone and they did not disappoint. For most of the operations that I wanted , like viewing live footage in different formats - panoramic, fish-eye or 360, the iPhone app is capable. Also capturing photos and videos directly from the phone, the app handles that well, as well as automatic stitching of files, to redden them for sharing. This is a major plus for Samsung, which allows its devices to be adopted by a wide base of users.

Operation is quite similar to the previous model, so I will not dwell on this. I got the sense that Samsung was trying to address the short comings of the previous model, with this one, so it is probably important that I pay attention to the differences. I have my original blog at (http://pro-blog.chitambira.com/2017/01/the-future-of-photography-is-here.html) and there, one can find information on the software, Action Director, that one can use to deal with the files. Just like with all 2-lens 360 cameras, one needs to take consideration of light sources when shooting. It is best practice to make sure that both lenses receive roughly same amount of light, so its best to point the nose of the camera to the light source than pointing one lens. However, having said than, I realised that the new camera deals with lighting much better than the previous one, so the light source issues are not prevalent. Stitched-up photos look more seamless this time.

Video quality has been greatly improved as expected because of the specs changes. To my layman eye, the videos are quite vivid now and also somewhat better stabilisation seems to be employed. On the hardware itself, the camera is IP53 certified, so is still dust and splash proof. However, there is no more the rubber-sealed door to the ports, I am wary of even letting splashes on my camera. The SD card and Type C USB ports are external and the battery is no longer removable (make what you want of this)







Generally this new camera offer better video quality, is smaller and lighter, and better battery life. The smaller size means that the distance/gap between the two lenses is reduced, leading to better stitched photos, no more blind zones. Performance is also great, quick response times for quick shots not using timers. The other thing I realised is the better sound quality on recorded videos. Previously, the sound in my beach videos was pretty bad.

Gear VR Headset

Samsung Gear VR is a well thought-out product that delivers true VR experience thru a simple affordable platform.
I have played around with my Gear VR well enough to know the true difference and benefits this gadget offers, when compared to other headsets.
First, we have to talk about the build quality of the device itself.  The key differentiation here is obviously the fact that this device comes with modular connector mechanism which allows you to interchange the connections from USB, USB type C or possibly other standards, by swapping the connection module.
Also the phone slot is adjustable to accommodate phones of different sizes.
The construction is plastic, obviously to keep weight and price low, but it comes with a good portion of cushion to deliver unparalleled comfort.
The lenses have a focus adjusting wheel which is much welcome especially for us who wear glasses. Now we do not need to wear the headset over our spectacles.
Another stroke of genius is the inclusion of on-board controls. You can control playback, menus etc even without the separate controller. this is especially useful in cases where one loses,  misplaces or simply do not have the Bluetooth controller.
The controller itself is a well made product, fitting snugly in the hand, well, placed buttons with a pistol trigger like button which works as the OK/Select button. The fact that you can also recenter it or modify its default aiming direction means it can be used by people with different handicaps or natural hand orientation.

It is possible to charge you phone while its still within the Gear VR. This is thanks to the USB Type C connection on the headset itself. If you connect this while playing, the headset will use the power from the charger directly, otherwise it will charge the phone inside.

Now we have to talk about the operation itself. Its comforting to know that one does not need to be a tech guru to operate this headset. Everything is straightforward. The key thing is that you only have to slot your phone in, and the VR software/platform spring into life. Just slot you Samsung phone into the glasses, and make sure the connector is firmly connected to the phone, and the Oculus system will automatically start (I talk more about the Oculs later)
Then we move on to the software platform itself.  The Gear VR provides hardware assisted rendering and features using the  Oculus technology and platform. The Gear VR is only compatible with Galaxy S6/S6 Edge or newer devices, so if your phone is not compatible as above, then you are out of luck.
However, there is a good reason why the compatibility is that much limited. For starters, these new Samsung phone have got good screen resolutions. For example, iPhone 6S has 1334 x 750 = 1,000,500 pixels, while Samsung Galaxy S6/Note4/5 etc has 2560 x 1440 = 3,686,400 pixels, thus almost 4x the resolution of iPhone, so the iPhone 6 or 6S would be terrible for VR.

Secondly, there is no VR operating system for iOS. The Samsung Gear VR includes an Oculus launch app, along with stores from both Samsung and Oculus. ... The iOS apps for iPhone does offer a rudimentary interface to some Google Cardboard apps, but not to all VR experiences available on other platforms. In simple words, the iPhone as it is at the moment, was never built with VR in mind.

Whilst one may be able to play Zombie shooter VR games on iPhone, the extent of movement and rendering is pre-defined within the game and the headset can not independently explore all the VR FOV (bound specified in the game or app) where as the Gear VR platform allows you to explore all possible dimensions. In terms of the experience, this can be summarised as a factual statement that one can be fooled to think they are in a different environment/place./world when using the Gear VR where as that is not possible with most budget headsets with which the iPhone may be compatible.

Watching and enjoying content created using the Gear360 camera, on your Gear VR means Samsung provides a full VR ecosystem which is easily accessible to the masses. The Gear VR headset obviously does not break your bank and the two Gear 360 cameras can be bought for a song on Amazon

The key thing as far as VR is concerned is content. What use does it servers when you can have a perfect VR headset, but without any content to  enjoy it with? Well if you are reading this and wondering the same, you are in luck. Samsung's teaming up with Oculus provides a platform that is pregnant with content and possibilities.

Oculus home screen

The most compeling downlods that you can use as proof of the unmatched imerseive capability of the Gear VR are the following appls (available within Oculus platform)
 (i) Try the VR effects especially Magga's dances on Amaze 3D Videos
(ii) Amazing Cinema offers an experience equivalent to watching Cinema on the night sky (with the sky being the screen, that's pretty awesome!!
(iii) Oculus Video offers videos and movies you can watch in realistic cinema setting if you want.
(iv) There are loads of other channels (apps) that can offer you a VR environment for your usual entertainment sources. These include  National Geo, CNN, Discovery etc.

There is also the meeting rooms where you can meet with your Facebook friends who are on the Oculus platform as well. Meeting in the virtual reality is just fun on its own, and you can strike conversations using the phone's microphones which make the whole experience unusual and fun.

A large selection of games are multiplayer, so you can play with friends over the internet. The Oculus platform makes use of Facebook for social networking, so if you have Facebook friends with an Oculus compatible VR headset, then fun-times will be unending...

Zombie shooting games are fun with the Gear VR. As already described above, the Oculus platform/operating system, allows an immersive environment which is adequate to fool your senses to feel and believe one is actually transported to a different place. This is possible because of the impeccable graphics capability, image resolution of the phone, and perfect head tracking and motion rendering capabilities of the sensors of the Gear VR headset. This combination is what most experts call the premium VR experience.

Overall, the Gear 360 and Gear VR are a must have gadgets for modern (or rather futuristic) entertainment. These are not half backed gimmicky devices, but real challengers which I think are worth your coins.

Samsung Galaxy Tab S3: Fantabstic side-kick!

I have been using the Tab for a number of weeks now and I am fairly comfortable, giving my 2 cents on this piece of kit. First, this is Samsung's first truly premium tablet. I have to describe its build and aesthetically features to demonstrate that fact. Unboxing
The Tab comes in a very nice dark grey box with seals for guarantee of "newness". Opening that box exposes some well thought-out and neatly packed items which include the S Pen, The Tab and the charger together with cable and documentation. The Tab itself will be in a dust proof sleeve, whose unfastening process actually gives you that kind of satisfaction, if you get what I mean.


Unboxed Tab

Unboxing this beauty was an awesome experience. As always, and often, I had the luxury of doing the unboxing, with my 2 best buddies who are 11 and 6 years old :D, Their reaction was very positive, and they liked what they saw. We have an unboxing video on periscope, can follow the link below

Looks and feel With the Tab S3 it is clear that Samsung are aiming for the most premium and complete android tablet experience. The metal rounded edges and glass back together with a light weight, only 429g, makes the tablet is perfectly balanced and fits very comfortably even in somewhat small hands.





Talking of premium look and feel, the AKG glass back of this tablet is just one such feature which gives the device its "Woohah!"

The screen is so vivid, as if things are about to spring into life. Using the tab, is like a kill, in broad-day-light. I mean literally, the screen is so vibrant that you are forced to wonder why there ever had been some tablets with screens that simply did not work in bright sun/day light. Simply this table is the best 'under the sun', excuse the pan.

Specifications, Hardware and S Pen The following is an overview of the specifications of this Tab;

Dimensions (mm) 237.30 x 169.00 x 6.00 Weight (g) 429g Battery capacity (mAh) 6000mAh Removable battery No
Screen size (inches) 9.7 inches Resolution 2048x1536 pixels
Processor 1.6GHz quad-core Processor make Qualcomm Snapdragon 820 RAM 4GB Internal storage 32GB Expandable storage Yes, microSD upto 256GB

Wi-Fi 802.11 a/b/g/n/ac GPS Yes Bluetooth Yes, v 4.20 NFC No Infrared No
Compass/ Magnetometer No Proximity sensor No Accelerometer Yes Ambient light sensor Yes Gyroscope Yes Barometer No Temperature sensor No
The S Pen is fantabulous, its thick enough to feel like a real pen and is quite sensitive. Air-play (or is it whats its called?) works like a charm, sensing the pen even whilst its still hanging up in the, Oh boy..."air"
The S-Pen is light weight and comfortable to use and obviously doesn’t need batteries or charging or some pairing process with the tab before use. It just works. The animated "swoosh" sound that plays as you write with the pen is quite satisfying, as if one is writing on a real paper. My handwriting is probably among the worst, people used to say I write like a medical doctor on hospital cards, but the Tab has always got the gist of what I would be trying to write, every time, Its magical.
Well, as it happens , my first test-drive included streaming my beloved Beatles collection in the background while I checked-out loads of other features. Its an understatement to say I was pleasantly surprised by the quality of the sound. My auditory orifices where quite elated on consuming such well-rounded acoustic and sonic energies. In simple words, top-quality audio... That quality audio is bellowed from 4 speakers at each of the rounded corners of the tab. Call it surround sound or what you will, I will call it perfect sound from a perfectly sound technology. Did I tell you this sort-of indulgence lasted a good half-day? (24hr day :D) Well, if that's not "New testament" to the battery capacity, I don't know what is. The Tab can pack a sizeable punch of AmpHours to make even Mayweather jealous. It makes the Tab go on and on and on like an energiser battery, and believe me, that's great staying power!, no one minute wonders... For once it feels good to own a mobile device that I don't have to charge every hour.



Competition I will not even let you search wildly in the market, for this Tab's competition, because there is only one. Without beating about the bust, the iPad Pro is the only competition here. Both Tabs come with a stylus, a metal frame, a vivid display and comparable size and weight.

So what separates them?

Its probably best that I don't waste time on obvious stuff, and stick to the issues. There are differences that some people may be interested in. Generally these two devices offer comparable value, so I will highlight the 3 areas where I believe you may notice differences.
First is the screen. You may want to head over to iPad pro 9.7' s specs to compare, buy simply, the Galaxy Tab S3 takes the crown here. The S3 Tab is HDR ready (High dynamic range) which allows to watch HDR content, bringing more sharp and vivid images onto the screen.

The second is the camera. Tab S3 has 13Mega Pixels compared to iPad Pro's 12MP, BUT the results from the iPad trounce the S3 by a country mile. Visually the sharpness of the images from the iPad is captivating. Could it be the True Tone flash? could it be the Live View functionality? my opinion is that the iPad wins on this one.


Lastly, but not least of-course, if the juice tank that keeps everything ticking, the battery. From my research (of-course i do not own the iPad pro 9.7) generally the iPad ticks for around 10hrs continuous use as compared to the Tab S3 which can go upto around 12hrs. It should be noted that the iPad battery is 7306mAh whereas the Tab S3 is 6000mAh. So the Galaxy tab wins on this one.


I have not forgotten about the issue of the pocket by the way. So I will simply say Samsung produced a device to give Apple a run for its money in this particular market. So it can generally be expected that Samsung's offering will equally break your bank in the same fashion your usual Apple device does.

The Tab S3 retail price is £599 including S pen (Standard 32GB WiFi model). It comes in black or silver colours.
The iPad Pro costs £549, plus £99 for Apple pencil (Standard 32GB WiFi model). It comes in silver, gold, space-grey and rose-gold colours.
So not much difference in price, (iPad cost £49 more) but indeed both tablets aim to search your pockets somehow, when compared to the rest of that market space... I do believe they deserve to, though...
I dressed my Tab S3 in quality gear that did not even break my bank. I am talking about the case and Bluetooth keyboard.

This device has become my companion, providing entertainment (I love movies and music) on the go. Funny enough, I have also found that its a formidable work device. I am "rdesktoping" to my work computer and enjoying both worlds simultaneously. Sometimes I am also using Google Docs to do a lot of business and work on the tab. Writing with the S Pen is making this a favourite of mine for any office work Kudos Samsung!
