CHARGEKEY – my obsession of stylish iPhone charge cable

11-21-2013_ChargeKey_Hero_Sidebyside_1200x1200

I own an apple iPhone 5 which I am totally in love with because of its design factor and powerful computing. My phone is my oxygen, it has evolved from need to necessity. As a regular traveler, it always run out of juice due to constant usage of songs, maps and social networking.

So i ended up carrying the iPhone charger with me always. Wherever i stop by, i look for a charge point in MRT, bus stations and airports.  After considerations, bought power bank to charge on-demand but still have to carry the long iPhone charge cable. Because these power banks usually don’t come up with lighting cable and iPhone does not use a standard charging port like other android phones.

This completely does not serve my purpose of carrying a slim phone with bulky charges and cables. Looking at options, I had opportunity to try the CHARGEKEY from Nomad.

ChargeKey-iPhone5It is a portable lighting cable that looks like a key chain. Best part is it is Apple Certified. It can charge and sync as well. Look at a situation where you need to copy some pictures from your iPhone and you can always pull up your keychain to do so.

Using Nomad CHARGEKEY for iPhone, I always feel like an international spy with high tech gadgets, it makes me distinct in a crowd. The best part is the key looks so thin and light but at the same time it is very rigid and rugged in quality.

It can hold your iPhone seriously !!!!!

How Two Factor Authentication should change in the future using mobile phone

This is my 50 cent suggestion of how two factor authentication should change in the future. With an increase in sites adopting them, you will end up having an average of more than 20 different two factor authentication codes in your mobile.

86/365+1 Cryptic

Two Factor Authentication codes via sms are just optional and purely dependent on your mobile network availability, i don’t prefer receiving sms codes for each of my sessions. The best so far is the Google Authenticator tool which is available in all cross platform mobile operating systems. So like an RSA key, the Authenticator tool can generate the codes offline and does not require data connection.

So what is going to happen in the future ?

I have 5 accounts linked with my Google Authenticator that includes my two google accounts, dreamhost, lastpass and dropbox. Evernote and Linkedin have introduced two factor authentication and they are going to be in queue for me.

There’s no doubt that i will end up having a minimum of 30 accounts very soon and the current Google Authenticator tool will let me scroll to search for my code out of this 30 accounts. By the time i locate the right account and enter the code, the time expires and code changes. So in terms of usability there is necessarily a change.

So here is my proposal (sorry if it sounds dumb)

Instead of entering the code manually for every account, each account added in Google Authenticator should have a unique callback url or Google should provide a push service which securely allows third party services to send request to our Google Authenticator client in our mobile.

Update: After having a discussion with my friend Srinivasan Annamalai, one of my Technology Evangelist, we concluded few things for better security and also in terms of usability, Google should provide a service to third party services which gives permission only to trigger an action to Generate Secure code associated with concerned account and pop up the same in user mobile screen (on-demand action).

So the next time you want to login using step two authentication, all you have to do is take your mobile, fire up the app and wait for a request made by your service provider to Google, the app will Generte code and pop it up. So you enter it. Thats it. Tada !

By this way you can manage N number of two factor accounts using a single authenticator application…

Penta T-Pad WS802c Hands on Review – Video

For those who have been keeping up with the news must be aware of Noida based Pantel Technologies which sells co-branded BSNL Tablets. Recently they launched a new higher end model called Penta T-Pad WS802C. I had a chance to try it and been using it for more than a week. So this was actually my second tablet after the ipad. One thing I could notice is that tablets are drastically changing the way we consume the content. Also we have vast array of choices for buying a tablet, which varies on aspects like features, hardware and cost. In India, cost is a potential factor for every product and that’s where T-pad WS802c impressed me.

Overview:
T-Pad WS802C is a budget tablet which comes around 14700 INR. With my hands-on experience, I am writing a personal review on it. To make things more clear and concise, I am going to split into topics. Ok here we go 🙂 You can also checkout the video above to feel the looks.

Specifications:
Powered by Cortex A8 1GHz, 512mb DDR2 Ram, 4GB internal memory and runs on Android 4.0.3 (Ice Cream Sandwich). It has dual camera (2mp rear + 0.3 front), GPS, 3G Sim Slot and other default stuffs. More detailed specs here.

Tablet Body:
Comes in white colour with 8” display, which is bigger than other budget variant. The back panel is a patterned white design with protective lamination that prevents scratches and gives good resistance. The Touch screen is very responsive like Samsung tab and Blackberry playbook. Overall body is made up of hard plastic and perfectly strong for a tablet.

Performance and Usage:
I performed several benchmark tests and certainly the tablet is up to the level on budget category. Boot speed is pretty quick but certainly at some point multi-tasking lags a little especially when 7+ applications are open same time. Sometimes it crashes and reboots completely. Tried playing couple of high end games and it is seamlessly fast but the negative factor is that it heats up very quickly. The Temperature is too high at some point where you cannot even hold it in your hand. Comparing other tablets in this segment this one emits more temperature. Seriously they need to consider redesigning their heat exhaust or sink.

Battery:
The total standby time is more than 6 hours but the battery drains very quickly within 4 hours on performing normal tasks. We also have to remember the fact that you can actually make calls; receive text messages in this tablet with a 2g/3g sim card. So turning of cellular network can increase your battery life.

Support:
The first question that sparks anyone when buying a brand which is unknown is the support and warranty. Unlike any Chinese products or Unfamiliar New Indian Brands, Pantel Technologies can be added to exception list because they have service centres all over India.

Comparison:
Here is my comparison with tablets in the same budget range.

Features T-Pad WS802C Huawei MediaPad HCL ME Tablet AM7-A1

Camera 2 mp + 0.3 mp 5 MP + 1.3 MP 1.3 MP
Standby Time 6 hours 6 Hours
Cost 14699 INR 19990 INR 18000 INR

 

Pros:

  1. 15,000 INR is a good price for this configuration
  2. Performance and Speed
  3. Touch sensitive is quite good
  4. Hard and Strong Tablet shell
  5. Warranty and Support Center all over India

Cons:

  1. Over Heating
  2. Battery Charging Time
  3. Uncomfortable menu buttons

Jailbreaking your iphone, ipad and ipod touch. Is it safe to do ?

There is a misconception going  about jailbreaking the latest iOS 5 devices. People say it will void your warranty and should do it only after the warranty period. Recently Apple is insisting application developers to create apps which detect modified handsets. Some apps keep popping up saying ” Jailbreak detected. App cannot run on this device.” . Jail breaking is legal but it does not cover the warranty and will void your warranty ! So should you jailbreak ? When you ask this question yourself, you need to understand what jailbreaking is and the necessity why you want to jailbreak ?

Jailbreaking is just a process of removing the restrictions posed on a device.  Just consider entering a country without a visa. Each and every app developed for ios device should go for a process of approval by Apple before they are listed in itunes. So inorder to enable more functionality and to install custom applications, we involve in the process of jailbreaking our devices. Usually a custom community Cydia is available for ios which acts as a platform for apps market for jailbreak devices. I came across some of the custom apps and have to adhere their functions and how useful they are.  My favourite one was the bluetooth dialup  network for ipod touch which enables me to use my ipod touch with 3g facility by bridging it with my blackberry.

The misconception with the users is that the current iOS 5 upgrade sends a signal to Apple saying that your iphone was jailbreaked and should ban this user from any support or warranty. This does not work that way, if you ask me i would tell it was just a rumor ! Atleast not now ! I have to agree that apple is trying to strengthen its device with a lot of security fixes. Jailbreak can be possible because of the security exploits and holes in the current software version but for every update Apple is trying to fix it up, we end up with a good jailbreaking tool 🙂

So my advice is if you really want to use some extra apps and try more out of your device, jailbreak your device but don’t forget to take a backup before you do it. But don’t forget just in case if you want to send your device for a warranty you need to restore it with the original firmware !

Buy and Sell in Internet with Sahipasand

sahipasand

It was yesterday that when i was looking for people selling second hand Enfield bikes i came across this simple and clean site called Sahipasand . At first i had no intent to browse through it as i thought it was just another random site with bot generated listing. But i tried my luck and found some reliable listing especially in my place Pondicherry.

To my surprise i can find more than 250 products alone in my city (Pondicherry) in different categories. This added to my interests and i began to explore some of the listings as well as features of the site.I thought it is a good idea to share a site like this to my readers. Sahipasand (right choice in Hindi) is a free classified site, where you can buy and sell anything for free. Yes you are right i could say its indian version of Craigslist !

One of the reasons why this site stands unique is that it has no ads; they don’t charge you for anything.  You dont have to pay for listing your ad or for contacting a seller. It’s completely free and you don’t even need to register. The site acts as a middleman to connect you to the seller/buyer free or charge 🙂

SahiPasand.com is owned by SCM Ventures which is under Schibsted ASA and its subsidiary Schibsted Classified Media (SCM).  SCM is currently the biggest online classified advertising company in Europe. The site looks elegant and simple so does the usability. With Sahipasand you can sell almost anything because they provide a wide range of categories to choose from like in ebay. They also have separate sections for selling cars, real estate and posting jobs . From the start the major thing i am obsessed about this site is its ease of use. You can simply narrow down your search and find what you are looking for!

Every listing is thoroughly checked and verified by the team and then it’s approved for listing. For example check this product listing where i ended up searching Enfield in Pondicherry. I can directly contact the buyer without any brokerage charges. Currently there are 45252 ads online which is good for a startup site.

Just browse through the site to experience yourself.

Using Underground Data Center to Store your Data.

Backup is a mandatory option for an individual as well as businesses. We have our own critical and confidential data that requires backup stored in some place is important. I usually use external hard disk to store my data like client docs, projects, resources, backup image and software applications. We also store them in DVD Disks which lasts long only upto 5 years. Hard disks too have their own read and write cycles which works upto an approximate lifespan but what if there arise a situtations like drive being stolen or damaged. You are out of choice and then only end up storing your data in the cloud.

There is a major concern over storing our valuable data in cloud when compared to storing it in our disks. Yes, its the privacy and security issue. When it comes to critical data like bank details, confidential documents, personal images, proofs.. we need a place where data can be secure, private as well as invulnerable to any means of risks and vandalism. My quest for a service online which overcomes my concern landed me in a different discussion. I seeked my cousin’s advice who is a product manager at Trend Micro. He told me about this trend called Underground Data centers. Its like Old wartime bunkers, caves, mountains turned down into a secure place for establishing Data centers.

When i was exploring about companies that have underground datacenters i came forward with this service called Mount10 (former name Swiss fort Knox) which stores all your date inside the Swiss Alps Mountain. Yeah i am not kidding..!! Mount 10 consists of two independent underground data centers inside the Swiss Alps which are being operated for storing, archiving and securing physical as well as electronic assets. The facilities are equipped with the latest technologies, physically separated by 10km and connected internally as well as with the Internet by a high performance network.

Why we should you go for Underground Data Centers ?

These type of Underground Datacenters are resistant against any known civil, terroristic and military threat including electro magnetic pulse and also offers protection against environmental disasters such as earth quakes, floods, landslides and large-scale fires. They are usually addressed as Zero Risk Infrastructure.

The folks at Mount10 had given me a 4GB Free Account for Lifetime Period for testing their servers. With the help of Mount10 Client i can automatically backup and sync in realtime.

This encryption key is the most important part, without which u cannot access your account and it is highly impossible to recover the key. Also you dont have to worry about your confidential and critical data being stored at their servers and being intercepted by someone since Mount10 uses 448-bit encryption technology the highest internet banking standards.
