BTRC Website is Down!!!

In our Digital Bangladesh, at this moment BTRC website (http://www.btrc.gov.bd/) is DOWN. I have checked from almost everywhere in world by my friends and others and they also failed to browse BTRC website.

It is almost more then 1 hour that The site is Down. Nobody seems care about the issue. Can you see the page? I really need some information on a license Guideline, but failed to get. Now where I will go and get the information?

Can anybody help me?

Fire Near Buriganga River

I saw fire and smoke from my rooftop about Half an Hour Ago. Then I called DMP Control Room know the location of Fire, but they don't have any information about any fire in City. I request operator to collect information via their wireless network. Request has just ignored and he give me phone number of Lalbagh Police Station to know details.

Without any delay I called Lalbagh Police Station, They also told me that they don't have any information regarding any fire and told me that might be any fire on dustbin near River. I requested him to collect information over police wireless network, same here. No information of Fire. Now I am in rooftop and watching the dark black smoke growing up.

God Knows What kind of duty DMP (Dhaka Metropolitan Police) do. As I can't find the location, I can't call fire service to take action. May Allah Save us.

I took 2 picture of smoke, but can't upload at this moment as I am connected with GP Internet and Connection is too slow to upload any picture at this moment. I will post any update here regarding this fire issue.

Fire is in 1km Radius of Chwalkbazar Telephone Exchange, which is almost near Buriganga River.

10+ mistakes Linux newbies make

New desktop users can make plenty of mistakes (as can anyone). But knowing which mistakes to avoid, from the start, helps prevent a LOT of frustration. I’ve handled the topic of mistakes new Linux admins make, but never those of desktop users. Here are some of the most common Linux desktop mistakes I see new users make.

Note: This article is also available as a PDF download.

1: Assuming they are using Windows

Although this might seem way too obvious, it’s not. The average user has no idea there are even different operating systems to be had. In fact, most average users couldn’t discern Windows XP from Vista from 7 (unless they are certain Windows 7 was “their idea”). Because of this, new users might believe that everything works (or doesn’t work, as the case may be) as it does in Windows. Make your end users aware that they are using a different operating system — and that it works differently.

2: Trying to make exe files work

Unless you have done your homework and installed WINE, double-clicking those .exe files simply won’t do anything. And when that happens, your end users are going to be upset. I have seen many an end user download an app made for Windows assuming that it will work for Linux. Make it clear to users that Linux, like Windows, will only run applications made for that operating system. This, of course, is tossed out the window when WINE is involved. But new users won’t be using WINE anyway.

3: Choosing the wrong distribution

One of the biggest problems for users is choosing the wrong distribution. Imagine being a new user and selecting Gentoo or Slackware or Fedora! Yes those are all good distributions, but any of them would send a new user running away in fear. If you are in the initial stages of helping a new user out, do yourselves both a favor and choose the distribution carefully. Consider the user’s ability, needs, and hardware before you make that selection. Don’t just jump on board Ubuntu because everyone says you should. A lot of distributions out there are made specifically for new users. Give them all a close examination before making the choice.

4: Not finding software

Because so many new Linux users are migrating from Windows, they think software can be had from the same channels. Most of the time, this is not the case. The new user needs to become familiar with their package management tools right away - especially tools like Synaptic, Packagekit, and Ubuntu Software Center. Each of those tools is a mecca of software where users can most likely find all the applications they need.

5: Sending OpenOffice documents to Microsoft Office users in the default format

I see this so often. New Linux users are proud of the strides they have made but dumbfounded (and sometimes turned back to Windows) because the people they share files with can’t read their formats. Remember, Microsoft products are not good at getting along with other operating systems and other applications. Make sure your new users are saving in file formats that are readable by the Microsoft equivalents.

6: Avoiding the command line

I can’t, for the life of me, figure out why people completely avoid the command line as if it is the most complex tool there is. I know people who can work absolute magic with Photoshop but can’t seem to type a simple rm command at the command line. Why this is I will never know. New users shouldn’t shy away from the command line. Knowing the command line isn’t essential anymore, but it will make them more capable users.

7: Giving up too quickly

Here’s another issue I see all too often. After a few hours (or a couple of days) working with Linux, new users will give up for one reason or another. I understand giving up when they realize something simply doesn’t work (such as when they MUST use a proprietary application or file format). But seeing Linux not work under average demands is rare these days. If you see new Linux users getting frustrated, try to give them a little extra guidance. Sometimes getting over that initial hump is the biggest challenge they will face.

8: Thinking the Windows directory hierarchy translates to Linux

There is no C:\ in Linux. Nor do you use the “\” character. Nor should you use spaces in filenames. These are common mistakes new users make. Trying to map out Windows to Linux, directory for directory, is impossible. You can get as far as C:\ = / and maybe Default User = ~/, but beyond that you’re out of luck. Make sure new users understand that everything starts at / and their most important directory is their home directory (aka ~/ aka /home/USERNAME/).

9: Skipping updates

I have been burned with Windows updates many times. Need I bother mentioning the update from Explorer 7 to Explorer 8? Very rarely has a Linux update fubar’d a system of mine. In fact, I can’t remember the last time it has. So I am always up to date on my systems… and with good reason. Those updates bring new security patches and features to software and should be applied. Having an installation with a security hole is not what your users need, especially on a machine that houses important information.

10: Logging in as root

I really shouldn’t have to say this. But just in case, be sure to tell your users DON’T LOG IN AS ROOT! But… just in case they must… DON’T LOG IN AS ROOT! Instead, have them open up a terminal window and either “su” to root or use “sudo”. And just in case you didn’t hear me the first time, DON’T LOG IN AS ROOT!

11: Losing windows to the pager

The pager is one of the handiest features of the Linux desktops. But over and over, I’ve seen that new users don’t quite understand what the pager is for and what it does. Because of this, they will “lose” their windows from the desktop. Where did it go? It was there a moment ago! I guess it crashed. No. More than likely, they moved it to another desktop. Another desktop? You see where this is going? Help the new user understand what the pager is and how useful it can be.

12: Ignoring security because it’s Linux

A big part of me still wants to boast and say, “In the 12 years I have used Linux, I have never once had a virus or worm or been hacked.” Although that is true, it doesn’t mean I should ignore security. I have witnessed the effects of a rootkit on a Linux machine. They aren’t pretty and data will be lost. Tell your users that they can’t ignore security just because they’re using Linux. Security is crucial, regardless of the OS.

FaceBook Things to Stop Doing Now URGENTLY

Facebook, a so called Social Networking Website, used by most of Internet User. But do you know what you are doing? People like me are providing such kind of information on their profile which is same as walking street without any cloth!! Yes, I mean it. To stop the identity thief or cyber criminal, you MUST do following things right now:

Protect Your Account with Strong Password:

Avoid simple names or words you can find in a dictionary, even with numbers tacked on the end. Instead, mix upper- and lower-case letters, numbers, and symbols. A password should have at least eight characters. One good technique is to insert numbers or symbols in the middle of a word, such as this variant on the word "houses": hO27usEs!

Leaving Your Full Birth Date in Your Profile:

It's an ideal target for identity thieves, who could use it to obtain more information about you and potentially gain access to your bank or credit card account. If you've already entered a birth date, go to your profile page and click on the Info tab, then on Edit Information. Under the Basic Information section, choose to show only the month and day or no birthday at all.

Overlooking Useful Privacy Controls

For almost everything in your Facebook profile, you can limit access to only your friends, friends of friends, or yourself. Restrict access to photos, birth date, religious views, and family information, among other things. You can give only certain people or groups access to items such as photos, or block particular people from seeing them. Consider leaving out contact info, such as phone number and address, since you probably don't want anyone to have access to that information anyway.

Posting Your Child's Name in a Caption

Don't use a child's name in photo tags or captions. If someone else does, delete it by clicking on Remove Tag. If your child isn't on Facebook and someone includes his or her name in a caption, ask that person to remove the name.

Mentioning That You'll Be Away From Home

That's like putting a "no one's home" sign on your door. Wait until you get home to tell everyone how awesome your vacation was and be vague about the date of any trip.

Letting Search Engines Find You

To help prevent strangers from accessing your page, go to the Search section of Facebook's privacy controls and select Only Friends for Facebook search results. Be sure the box for public search results isn't checked.

Permitting Youngsters to Use Facebook Unsupervised

Facebook limits its members to ages 13 and over, but children younger than that do use it. If you have a young child or teenager on Facebook, the best way to provide oversight is to become one of their online friends. Use your e-mail address as the contact for their account so that you receive their notifications and monitor their activities. "What they think is nothing can actually be pretty serious," says Charles Pavelites, a supervisory special agent at the Internet Crime Complaint Center. For example, a child who posts the comment "Mom will be home soon, I need to do the dishes" every day at the same time is revealing too much about the parents' regular comings and goings.

Warning: Sending Useless Data to /dev/null Create CPU Hot and Sending to /dev/random Make Network Angry!!

We, the so called 'SysAdmins' including me have habit to send useless data to '/dev/null' to destroy it forever. Bye they way '/dev/null' is an special virtual device on Linux / Unix / BSD like system (Operating System) .

I am wandering to know that sending / redirecting useless data to /dev/null is just creating heat! Yes, every byte send to '/dev/null' is converted as heat, increase temperature of CPU finally environment.

It goes into a special data sink in the CPU where it is converted to heat which is vented through the heatsink / fan assembly. This is why CPU cooling is increasingly important; as people get used to faster processors, they become careless with their data and more and more of it ends up in /dev/null, overheating their CPUs. If you delete /dev/null (which effectively disables the CPU data sink) your CPU may run cooler but your system will quickly become constipated with all that excess data and start to behave erratically. If you have a fast network connection you can cool down your CPU by reading data out of /dev/random and sending it off somewhere; however you run the risk of overheating your network connection and / or angering your ISP, as most of the data will end up getting converted to heat by their equipment, but they generally have good cooling, so if you do not overdo it you should be OK - From FreeBSD Manual

On that manual Mr. Paul Robinson show other method which will not generate any heat. He added:

There are other methods. As every good sysadmin knows, it is part of standard practice to send data to the screen of interesting variety to keep all the pixies that make up your picture happy. Screen pixies (commonly mis-typed or re-named as “pixels”) are categorized by the type of hat they wear (red, green or blue) and will hide or appear (thereby showing the color of their hat) whenever they receive a little piece of food. Video cards turn data into pixie-food, and then send them to the pixies -- the more expensive the card, the better the food, so the better behaved the pixies are. They also need constant stimulation -- this is why screen savers exist.

To take your suggestions further, you could just throw the random data to console, thereby letting the pixies consume it. This causes no heat to be produced at all, keeps the pixies happy and gets rid of your data quite quickly, even if it does make things look a bit messy on your screen.

Incidentally, as an ex-admin of a large ISP who experienced many problems attempting to maintain a stable temperature in a server room, I would strongly discourage people sending the data they do not want out to the network. The fairies who do the packet switching and routing get annoyed by it as well.

Now it's your choice, /dev/null or /dev/random or console or another place, where I am waiting to receive your data to get a credit card number or financial data;)

Lockdown Facebook Profile to Protect Privacy and Security

Jason Perlow is a technologist with over two decades of experience integrating large heterogeneous multi-vendor computing environments in Fortune 500 companies decided after all of FaceBook’s continual invasions on his personal privacy by sharing data to people and services which he don’t want — and by being completely irresponsible and untrustworthy in terms of computer security — that it was time to lock down his profile and minimize his exposure, while still allowing select people to interact with him on his user Profile.

With FaceBook, this is a very difficult thing to be able to balance, and he still not 100 percent sure that he wouldn't be served by destroying his profile and leaving the service altogether, but I believe that for the time being, I’ve been able to create some sort of “miserable medium” that he can tolerate. This is the advice about Facebook Profile Security from Mr. Jason Perlow.

Are you agree with him? To read more of his blog related to Facebook Profile Security & Privacy, Click Here

FaceBook is an extremely complicated and confusing online service to use, with lots of settings that are needed to secure a profile and prevent undesired dissemination of information. Because I no longer trust the service whatsoever, I’ve created a “How-To” for the advanced user for locking down their profile and minimizing their risk

Keep in mind that this Lockdown I created is an extremely draconian method — nobody will be able to share your information or your statuses, you will not have any personally identifying information unless you absolutely chose to, and only the most essential applications will be authorized.

The user for which I have in mind is someone who is extremely concerned about their personal privacy and security, but also may wish to have people contact them via a brand or a business or some other following they maintain - Jason perlow

He also wrote about Twitter.Com, another micro blog service. His full writing can be found here and don't forget to post your comments. I wish to know what you think about he privacy & security of social networking sites.

Google Mail is becoming Gmail in the UK - 60 Million Keystroke Save per Day

Google Mail is becoming Gmail in the UK - Official Gmail Blog:

"If you already have a Google email account in the UK, you'll soon have the option to switch your existing @googlemail.com address to the matching @gmail.com one, but you're also free to stick with @googlemail.com. And starting later this week, anybody who signs up for a new account in the UK will get an @gmail.com address. Since 'gmail' is 50% fewer characters than 'googlemail,' we estimate this name change will save approximately 60 million keystrokes a day. At about 217 microjoules per keystroke, that's about the energy of 20 bonbons saved every day!"

UK @GOOGLEMAIL.COM Switch to @GMAIL.Com will Save 60 Million Keystrokes Equals to 20 Bonbons of Energy!

Almost everyone using @gmail.com knows that email to someone@gmail.com and someone@googlemail.com will reach same inbox. In UK Google Email User by Default get @googlemail.com during signup. Recently Google's Gmail Official Blog Announced that by next week by default Google Email page will give option to switch existing user to use @gmail.com instead of @googlemail.com.

If you already have a Google email account in the UK, you'll soon have the option to switch your existing @googlemail.com address to the matching @gmail.com one, but you're also free to stick with @googlemail.com.

At about 217 microjoules per keystroke, that's about the energy of 20 bonbons saved every day! - Article of UK Google Email user on Google Gmail Official Blog

See, how much big Google is, just removing 4 Character from Email address will Save about 60 million keystroke per day which is about 217 microjules per keystroke and 20 bonbons energy per day!!!

If Google can reduce power consumption, why not we can save power for Bangladesh? Hope to Write more about saving on my Green Bangladesh Blog very soon.

Thanks to all
