How to increase validity of BSNL sim card when online recharge failed

Rawi G — Mon, 31 Dec 2012 16:46:22 +0000

Easy way to increase validity of BSNL sim card ( prepaid) is as follows. Once your voice plan expired and getting IVR message account suspended then none of on-line recharge options works.

Recharging with 3G data not going to extend BSNL prepaid sim card validity. So once your voice account suspend or sim validity over. You need to recharge with any new prepaid plans available at that time and that too from BSNL reseller or agent.

Although on-line plan continue,change of plan recharge options available, it never works on expired/validity expired accounts.

I am keeping one BSNL sim past 2 years for 3G data purpose and recently i faced this problem. Still today BSNL only giving 3G speeds far better than Docomo,Aircel or Voda.

Rawi G — Sun, 30 Dec 2012 02:36:58 +0000

We can use software based TOTP client token generator, which can run on PC instead of hardware devices to enable multi-factor authentication for all Amazon cloud services. So no need to carry another token device in your pocket.

How to enable multi factor authentication for Amazon cloud services with TOTP software OTP token generator that can run on Windows and Linux ?

MFA ( Multi-Factor authentication) is best security option to safe guard your Amazon cloud service accounts. Once you enable mfa, along with password , you need to enter one time password generated by your hardware token device.

Up to now, you need to buy hardware device separately to enable MFA from Amazon. Now Amazon allowing software based one time password generators.

But issue is most of the OTP software token generator are mobile phone based. Most of them are not PC compatible. Even Amazon site showing many TOTP software clients but none of them working with Amazon.

Here is the best freeware OTP Java based TOTP (Time-Based One-Time Password) software token generator that one can run on Windows as well as Linux.Ut is compatible with Amazon as well as Google multi-facto authentication.

In case, if you using any other PC based OTP software, please share here by leaving your comment.

How to run native Evernote desktop client for windows under Linux

Alternatives to Evernote never worked for me properly ( example: Nevernote). So I am limited to web version of Evernote. Long back tried to run Evernote in Linux using WINE but not worked. Few days back I made my new lapotp as server and started using my old 1GB laptop for day to day use. That is different project, will share in other post.

Centos 6 + minimal Gnome desktop +xfce combination made good laptop for day to day use. I am using Foxit pdf reader as pdf reader using Wine. So while installing Foxit, tried latest version of Evernote desktop client (4.6) just to check if it working or not. Amazing ! now this time Evernote client working fine.

Here is my free -m o/p of laptop with full load ( Firefox with 5 tabs + Chrome 3 tabs + Evernote Gui +Terminal with yum update + Gnome minimal desktop

[root@localhost ~]# free -m
total       used       free     shared    buffers     cached
Mem:          1006        952         54          0         28        596

Why Humans trust pets than fellow Human here is the reason

Rawi G — Tue, 11 Sep 2012 09:22:44 +0000

Once upon a time family members means humans but now family members mean incude humans and pets also. Why human likes pets than fellow human?

Trust and confidence on pets. Pets never cheat you for property. They never back stab you. They never demand for expensive things . Most importantly PETS listen you and follows your instructions. Some times PETS like dogs acts smart than you and saves you from trouble. Person victim of cheating by other person tend to trust PETS than other human.

Controlling others is most liked thing by us. Humans love to control others. Is this one of the reason of increasing pet love? Anyone likes PET that never listen his/her commands?
