All Queries are ivited....

Don’t buy power bank before you read this

1) What’s power bank?
Power bank serve as an ‘extra battery’ or external charger for your phone or other electronic devices.

2) Where is power bank made from?
Majority of the power banks in the market are actually made in China.

3) How do I charge the power bank?
You can charge your power bank via the charger that came with your phone, computer usb port or using other power bank

4) How long do I need to charge the power bank?
It’s depending on the REAL CAPACITY of the power bank. The larger REAL CAPACITY, the longer charging time may required. Different charging methods may result different charging time as well. Charging with the original charger will be faster than charging with computer usb port.

5) Why sometime I need longer time to charge the same power bank?
Even though using the same charging method, the charging time may be differ due to environment,temperature, power flow and etc

6) What is mAh?
mAh mean milli Ampere Hour, the capacity of the power bank is measure with mAh

7) A 12000mAh REAL CAPACITY power bank, able to charge a 1500mAh capacity phone for 8 times full?
This is a common mistake make by most of the people. For rough calculation of the total charge time, kindly use this formula
REAL CAPACITY * conversion rate * phone battery health / phone capacity = total charge times
EXAMPLE: 12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (0.5-1 times plus minus)

8) What’s conversation rate?
Conversation rate is the remaining percentage of the battery after the battery lost in heat or PCB operation.

9) What’s phone battery health?
In simple, it’s mean how‘healthy’ your phone battery is. Phone battery storage capacity will be lower and lower. That’s also the reason why our phone can last longer when it’s newly bought than after 3-6 months we used it. Different mobile phone models also will affect the calculation as some phone drain battery faster than the other.

10) What’s PCB?
PCB means Printed Circuit Board,its control all the operation flow inside the power bank. A good quality PCB will allow the power bank to charge more and have better durability

11) What’s 18650 power bank and what’s Li-Polymer power bank?
The common type will be 18650 and a better type will be Li-Polymer

12) What’s the different between 18650 and Li-Polymer?
- 18650 size and dimension are fix. Li-Polymer size and dimension are flexible.
- 18650 produce more heat. Li-Polymer are much more safer
- 18650 are cheaper. Li-Polymer are more expensive
- 18650 have higher self discharge rate.Li-Polymer have a very low self discharge rate
- 18650 battery durability will drop faster.  Li-Polymer battery capacity are more durable

13) What’s the common mAh use in 18650?
Common mAh use in 18650 is around 1300mAh to 2200mAh.

14) What’s the common REAL CAPACITY in 18650 power bank in the market?
- Power bank using 1pcs 18650 is 1200mAh – 2600mAh
- Power bank using 2pcs 18650 is 2500mAh – 4400mAh
- Power bank using 3pcs 18650 is 3750mAh – 6600mAh
- Power bank using 4pcs 18650 is 5200mAh – 8800mAh
- Power bank using 5pcs 18650 is 6500mAh –11000mAh
- Power bank using 6pcs 18650 is 7800mAh –13200mAh
- Power bank using 7pcs 18650 (no info)
- Power bank using 8pcs 18650 is 10400mAh –14400mAh

15) Is there any power bank use higher than 2200mAh per 18650?
Yes. There are, but it’s not common due to the expensive pricing.

16) What’s the different between branded power bank and generic power bank?
Branded power bank mostly sell in REAL CAPACITY. Generic power bank mostly sell in MARKING CAPACITY. That’s the reason why you will never see any branded power bank (standard size) have anything as high as 30000mAh – 50000mAh. That’s also the reason why a good 12000-13000mAh power bank are able to charge more or about the same like the market 30000-50000mAh power bank

17)  Is it true branded power bank won’t explode and generic power bank will explode?
Anything to do with battery, will have chance to explode. No matter it’s branded power bank or generic power bank.But chances for both branded and generic power bank to explode are near to 0%.If power bank is easy to explode, everyone will use power bank in war instead of bomb

Generate CSR for Red Hat Linux Apache / SSL Server

Step 1: Generating the Private Key

   1. Use the cd command to move to the /etc/httpd/conf directory.

   2. As root, type in one of the following three commands to generate your key:

   3. If you're using Official Red Hat Linux Professional and you want to use the included password feature, type in the following command: make genkey

   4. Your key will be generated and you will be asked to enter and confirm a password. Please note that you will need to remember and enter this password every time you start your secure Web server, so don't forget it.

   5. If you're using Official Red Hat Linux Professional and you don't want to be required to type in a password every time you start your secure Web server, use the following command instead of make genkey to create your key (note that the following command should be typed in all on one line): 

            /usr/sbin/sslgenrsa -rand /dev/urandom -out ssl.key/server.key 2048

   6. Then use the following command to set the correct permissions on your key: 

            chmod go-rwx ssl.key/server.key

   7. If you use the above commands to create your key, you will not need to use a password to start your secure Web server. However, we don't recommend that you disable the password feature for your secure Web server, since it decreases the level of security for your server.

   8. Your key will be created and saved to a file named server.key. If you're using Official Red Hat Linux Professional, server.key will be located in the /etc/httpd/conf/ssl.key directory. If you're using Official Red Hat Linux Professional, International Edition, server.key will be located in /etc/httpd/conf.

Step 2: Create the Certificate Signing Request

   1. In the /etc/httpd/conf directory, become root and type in one of the following two commands:

   2. If you're using Official Red Hat Linux Professional, type in the following command: 
           make certreq

   3. If you're using Official Red Hat Linux Professional, International Edition, type in the following single command (all on one line): 
           /usr/bin/openssl req -new -key /etc/httpd/conf/server.key -out /etc/httpd/conf/server.csr

   4. You will be prompted for your password (if you used a password when you generated your key). Type in the password, if necessary.

   5. You'll see some instructions and you will be prompted for responses. Your inputs will be incorporated into the CSR.

   6. When you've finished entering your information, a file named server.csr will be created. If you're using Official Red Hat Linux Professional, server.csr will be located in the /etc/httpd/conf/ssl.csr directory.

   7. You have just created a key pair and a CSR.

   8. The server.csr file contains your certificate request. To copy and paste the information into the orderform, open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).

   9. Go to our website ssl.nu for the SSL Certicate request

Micromax's Yu Yureka With 64-Bit Octa-Core SoC, Cyanogen OS Launched at Rs. 8,999

Micromax's new Yu brand of Cyanogen OS-based smartphones were unveiled on Thursday with the launch of Yu Yureka. The smartphone, priced at Rs. 8,999, will go up for registrations via Amazon on Friday (2pm IST), and it will start shipping in the second week of January.

Early adopters will get a leather back cover worth Rs. 999 free. Notably, the company is also touting "free replacement or repair" at the user's doorstep. The Yu Yureka (AO5510) smartphone runs on a custom-build of Cyanogen OS, Cyanogen OS 11, what Rahul Sharma, co-founder of Micromax, calls the "temple of customisation" and "Android on steroids", boasting of the "thousands of features over and above stock Android."

Micromax's Yu Yureka smartphone features dual-SIM support, with slots for Micro-SIM cards (4G+3G). It bears a 5.5-inch HD (720x1280 pixels) IPS display with a pixel density of 267ppi and Gorilla Glass 3 protection. The smartphone notably also features Cat. 4 4G LTE connectivity with up to 150Mbps download speeds and 50Mbps upload speeds, apart from Band 40 and Band 3 support.

It runs on a 64-bit 1.5GHz octa-core Snapdragon 615 SoC (MSM8939), coupled with Adreno 405 GPU and 2GB of RAM. The Yu Yureka bears a 13-megapixel Sony Exmor CMOS sensor rear autofocus camera with an f/2.2 aperture and flash. A front-facing 5-megapixel fixed-focus camera is also onboard.

The Yureka comes with 16GB of inbuilt storage expandable via microSD card (up to 32GB), and sports a 2500mAh Li-Po battery claiming talk time up to 8 hours, standby time up to 310 hours, video playback time of up to six hours, and gaming up to 4 hours. 

The Yu Yureka measures 154.8x78x8.8mm. Connectivity options include Bluetooth 4.0, Micro-USB, Wi-Fi 802.11 b/g/n, GPS, and a 3.5mm audio jack. Onboard sensors include an accelerometer, proximity sensor, ambient light sensor, and gyroscope.

The Cyanogen OS 11 build is based on Android 4.4.4 KitKat, and an Android 5.0 Lollipop-based build is promised.

Co-founders of Cyanogen Inc, Kurt McMaster and Steve Kondik, appeared at the event via webcast, and spoke about their early motivation for creating CyanogenMod, wanting to "modify and change Android" to create a mobile platform with the features "they wanted to see" on the open source operating system.

McMaster said there was a "level of stagnation in the smartphone market ever since Steve Jobs unveiled the iPhone, where the predominant mobile paradigm was to swipe, tap, and open an app." He explained how Cyanogen set out to defeat that paradigm. He added that the partnership will see the company bring a number of global and local services to Cyanogen in India, which he described as the the fastest growing smartphone market in the world, "There's a battle being fought in India, and Cyanogen+Yu, we intend to win that battle."

Other Cyanogen executives present at the event spoke of the 'personalisation, security, performance' of Cyanogen OS. Starting with customisations, Cyanogen stressed that Yu users will be able to modify icons, fonts, boot screen animation, taps, and more via the Themes app that will debut on the smartphone. Two free custom Yu themes will be available at launch.

As for privacy, Cyanogen said users will be able to edit and customise permissions of each app, apart from use features like Find & Wipe device, device encryption, Pin Scramble, Blacklist for spam callers, and a Protected Apps section.

Speaking about performance, Cyanogen executives detailed the camera and gallery apps of Cyanogen OS 11, and said that the current slow mo functionality at @60fps will be boosted to 120fps soon. The company also detailed that the highly-anticipated third-party Android continuity feature, NextBit Baton, which allows for backup and cloud synchronisation of logins, apart from app data and settings, will debut on the Yu Yureka. The NextBit Baton Pass feature lets users continue their work on another device. The AudioFX app's 24-bit high-res lossless audio was also emphasised.

Interestingly, Sharma clarified that the Yureka phone will feature an unlockable bootloader, kernel source, and full Android build tree. As for power users, Micromax claims warranty will not be voided on rooting the smartphone. Commenting on the feature, Sharma said, "You are the master, you control your destiny, you create the software, we'll put it on your devices."

Reset root password in Ubuntu

If for any reason(s) you forgot your Ubuntu root password, then you have a chance to reset the password without causing any issues. This may be a concern to some of us why its been made possible to reset Ubuntu root password but if we are to think outside the box, this could only happen if your machine is not secured physically hence someone is able to do this.

Lets not forget that the best form of securing your system is encrypting the hard drive, that way no one can steal my information. The idea of removing the drive and slaving it elsewhere is defeated since the encrypted drive will not be accessible.

Only do this if its necessary and if you know what you are doing

Reset Root Password

- Boot up your Ubuntu machine, and after the BIOS screen, press ESC key. On the GNU GRUB menu, select *Advanced options for Ubuntu

- On next screen, select select appropriate recovery mode and press Enter

- On recovery menu, select ‘root – Drop to root shell prompt’

- From the prompt menu, you need to remount the filesystem to have write permission

mount -rw -o remount /

- Now check the user available

ls /home/

- Now reset the user password. In my case, its sysadmin

passwd sysadmin

- When done, exit and resume boot
