Password Protection : Things to do before die

The sub-topic was just for humor. Well, Password protection for sure falls under the things-to-do lists. We often ignore it’s importance , but should never underestimate.
To protect access to the computer, every user account should have a password. Following are the course of action or advices to choose a strong password:-

1.Always assign a password to the Administrator account to prevent unauthorized access to the account.

2.Define whether the Administrator or the users will control passwords.In most cases users should control their passwords.

3.Use passwords that are hard to guess. For example, avoid using passwords with an noticeable association, such as family member’s name. Using real name, a username, or a company names makes for an easy-to-guess password. Avoid using common passwords such as “letmein” or “password” or same password as user’s name.

4.Using common dictionary word makes you exposed to automated programs that are designed to guess passwords.

5.Using any password that you write down or that you share with someone else is not secure.

6.Passwords can contain up to 128 characters, a minimum length of 8 characters is recommended.

7.Include both UPPERCASE and lowercase letters, numbers and valid non alphanumeric characters(such a punctuation).

8.Using no password at all is not a good practice because in an unsecured computer users easily can just walk in and log on.

9.Length, complex, variation and variety are the four things to consider while creating a strong password.

10.Complex passwords are secure, but if user’s find it difficult to remember, then an alternative way can be to use pass phrase like a sentence or two.

11.For example : Complex password : C0mplexP@$$w0rd
Pass phrase: A quick brown fox jumps over the lazy dog.

Test the strength of your passwords here

Windows 8 Advanced Startup Options

Windows 8 have come a long way to add several new features which give you some great options for fixing your PC.
Windows is trying really hard to give its best. It seems that the more recent the operating system, the less you have to reinstall it. The improvements in the OS help to prevent programs, and also users, from adversely affecting the PC’s performance.
Earlier Windows OS:
Earlier Windows versions had fewer startup options: There was
-Safe Mode and VGA mode,
-and you could enable boot logging or debugging mode.
-There was also the Last Known Good Configuration.
Safe Mode is still a great idea – load up only the most basic set of hardware drivers. Since so many software problems can be traced back to a faulty or incompatible hardware driver, the ability to turn them all off is still a hugely valuable troubleshooting technique.
Debugging Mode is beyond what most users do to repair their system. It’s great for engineers, but requires too much training to be used by regular PC users.
Using the Last Known Good Configuration was a great idea, too. The concept was simple – if the settings make it all the way to the end of the session, they must have worked. Save them and call them “Last Known Good”. It was a step in the right direction.
Windows 7 Advanced Startup getting really good:
The Advanced Boot Options for Vista and Windows 7 was even better. You could change your PC to no longer reboot automatically after a system crash right from the startup options.
And in addition to the original options, you could now run Memory Diagnostics, System Restore, and even automatically repair many common problems from the advanced startup options.
-Safe Mode
-Safe Mode with Networking
-Safe Mode with Command Prompt
-Enable Boot Logging
-Last Knows Good Configuration(advanced)
-Disable Automatic Restart on System Failure, etc
were some of the options in Advanced startup.
Windows 8 Advanced Startup Options are the best ever been:
When your computer isn’t running right, you’ll really appreciate just how advanced the new advanced startup options are for Windows 8.
Refresh and Reset are the first two options. They are brand new, and they have gotten quite a lot of attention the newest features in the advanced startup menu.
Refresh is a heavy duty cleaning of your computer – but leaves your personal data intact. It also removes programs in the classic desktop mode. However, you keep the Metro programs that you installed from Windows Store.
Personalization settings (desktop background, screen resolution, picture password) are kept. PC Settings (network settings, hardware drivers, windows features) are removed or set to defaults.
Reset is the equivalent of doing a factory reset. It brings your computer back to the way it was when you got it, or at least when it was new. All programs have to be reinstalled, and your personal data is gone, too. You’ll need to backup any data that you’ll want to keep before doing this and Windows 8 gives you very clear warnings about what’s about to happen to your data if you proceed.In fact, you’re actually given two options when you’re doing a Reset. You can either remove the files, or you can remove the files and “scrub the hard drive”, making it more difficult for somebody to recover the deleted files.
Even more advanced options in Windows 8 Advanced Startup
-System Restore puts the PC settings back to the way they were at the last Restore Point
-System Image Recovery is a full restore from a backed-up System Image File
-Automatic Repair Fixes a lot of problems for you
-Command Prompt when you just need to have a little access
-Startup Settings includes all of the original Advanced Repair Options like Safe Mode

ICT and Climate Change

Nepal Russia ICT Society does a monthly event called Technology Transfer and this month’s (February 2012) episode was on ICT and climate change. Strange as it sounds (in Nepal), the topic was something that should concern every IT and Non IT People and Professionals.

I almost missed this event and was in dilemma because, i arrived venue before time (actually 1 hour earlier). Dilemma in the sense that I along with my 4 other friends reached Russian Culture Center but neither banners was hung nor the hosts had arrived. The funniest part was that my friends had placed a bet to beat me up if the program doesn’t happen. All thanks to the 33 crores gods and goddess, who saved me and the program started at 05:15 pm.

kiran khanal sirBefore the ICT and Climate Change presentation, there was a short,sweet,quick and informative presentation on “Android Development Overview“, by Kiran khanal, Coordinator, Kantipur City College(KCC). I could only note down few things on my diary. The highlights were :

  1. Android is free open source.
  2. Why Android? – Because transferring application to phone is trivial – can distribute by putting it on the web – Android Market for wider distribution.
  3. Cupcake, Donut, Eclair, Froyo and IceCreamSandwich are the releases of Android Mobile Operating System .
  4. According to a survey in 2012, Android 2.3.3 is the most used Mobile OS among Android family.
  5. discussed shortly about the Android Architecture.
  6. Advantage of Mobile OS -always with user, -typically have Internet access, -typically have GPS enabled, -typically have accelerometer and compass, -most have camera’s and microphones, -many apps are free or low cost
  7. Disadvantage were -limited screen size, -limited battery, -limited processor speed, -limited and sometimes slow network access
  8. Development process for android app including setup, development, debugging and testing, publishing
  9. Apps are built using java and new SDK’s (Software Development Kit)
  10. Requires $25 to publish app in android market.

ICT and Climate Change
Achyuta Nand MishraMr. Achyuta Nanda Mishra, Assistant Director, Nepal Telecommunications Authority presented a paper on this topic. He indicated the climate change and its relationship with ICT sector. I noted a point that read, ” energy sector is responsible for about (3/4)th of total carbon di oxide emissions. He talked about how ICT positively contributes to climate change by making business more efficient and less polluting, by reducing energy required for productivity in various areas, facilitating monitoring and modelling of climate change, etc.

Negatively too ICT contributes in climate change by releasing Green House Gases (GHG), from 2 to 2.5 percent of GHG is contributed by ICT sector. He explained to us, how mitigating impact can be done by improvement in energy efficiency, increase use of renewal energy,cisco device is also an example of device that helps in resource utilization, reducing travel requirements. He also informed us that Nepal Telecom is bringing forward the concept of resource sharing with other Operators to contribute in climate change positively.

The Master of Ceremony Prakash Neupane conducted the event in which more than 60 representatives of Kathmandu IT institutions and colleges took part in the program. After the presentation the speaker answered various queries raised by the participants and lastly group photo following tea-biscuit session.

My view on Mozilla South Asia Inter-Community Meetup

Since I broke my leg and had to rest for almost a month, the laziness had been eating my mind slowly. So, as soon as i heard that there was a Mozilla Inter -Community meetup on the occasion of Open Data Day, I sprung into action. I told my legs lets go buddy — and indeed it was a fruitful event.
Different Mozilla communities from South Asia like Mozilla India, Mozilla Srilanka, Mozilla Bangladesh, Mozilla Pakistan were in deep community interactions, presentations, Q & A’s, Demo’s too.
I came to know that there were different activities planned as today was Open Data Day 2012. The activities were

  1. Presentation on Open Data
  2. Open Data Hackathon
  3. Mapathon
  4. Wikithon
  5. Localization Sprint
  6. Open Data Stalls
  7. and

  8. Mozilla Public Event

I happen to attend the last event of the day, actually second last (will talk about it later). I was excited to attend this event, not because just THE Mozilla the Web Browser but because of the local community heroes from different countries including Nepal. Yes, I happen to be a big Community fan, “sharing is caring” is what i believe. Heroes are not the one’s who fight villains and save heroines (i used plural here because in community there’s more than one), but the one’s who contribute to the community whether it be technical or non-technical.

There was an interactive session with the Mozilla Community Members which started community introduction. Later “B2G (Firefox OS) apps development” live demo presentation was shown. Pardon my mistakes, but it takes me a while to remember names,so i don’t remember the presenters name (let’s say them HEROES). So the heroes shared a lot to us.
Some key point i understood (see + hear) are :

  • Mozilla has partnered with a Spanish company and for hardware specification with ZTE to avoid complications using Firefox OS
  • You can install Firefox OS Simulator add-on to work on Firefox OS and the shortcut key is SHIFT+F2.
  • to look into the future of web API, you can visit http://www.arewemobileyet.com.
  • Some more Mozilla products like Mozilla webmaker, X-ray goggles, pop corn maker were also introduced to us
  • I thought pop corn maker was a device to make pop corn — until now, but (jokes apart) i came to know that its a tool to interact with video like never before.
  • Also most importantly about the localization part, i knew that Nepali localization of Firefox OS has been completed, although it’s in development phase we can try it out.

For the unofficial (backstage) Q&A, i asked Mozilla India community friend, about my Queries and he answered my queries with examples, short stories including the gesture and posture too. (jokes apart) i enjoyed the free & frank conversation.

last event
And yeah! how can we forget the Tech Guru’s (LOL intended) Mr. Hempal Shrestha and Mr. Prakash Neupane who kidnapped (not actually) us into a room for another interactive session by saying ” LET’S TAKE A GROUP PICTURE”. Well this was the most interactive session where actually something was written on white board (haha), funny too and moving around one question. Everyone expressed their views (with words and debates too) and the white board was full of points.

Local Users and Groups

To quickly navigate through command prompt, Go to command prompt and type lusrmgr.msc
cmd lusrmgr

Now, you can see Local Users and Groups window
local users and groups

By default there will be 3 built-in accounts Administrator, Guest and HomeGroup users:

  • Administrator – for administering accounts in computer
  • Guest – for administering guest accounts in computer
  • HomeGroup – for administering homegroup accounts to users

As u go on creating new user accounts, they will be added to the list. Every user created goes to users folder and every group created goes to groups folder. Remember that the users and groups created are for that computer, and thus its said local users and groups.

Below snapshot shows the Build-in groups as well as later added ones. For example, the group _vmware_ was added after the installation of third party software VMware Workstation.

Groups - local users and groups
