Downloading with 'wget' in Lubuntu

0
A slim download application has been added in Lubuntu 12.04 by default. It's name is 'wget'. 'WGET' can download from anywhere in the world of web. The great information about this terminal based application is that it support resuming. Retrieving files from the web with this light/ minimalist application is really funny and helpful for low memory. But you can use "Uget", if you do not like terminal based application. I am downloading latest famous Ubuntu magazine 'Full circle magazine (issue 62)' with wget on the above screenshot. Here is some talks about 'wget' which I found at 'Synaptic package manager'.

Have not download Ubuntu 11.04

0
I have not download Ubuntu 11.04, because I have not feel any attraction to this newer release. The main reason is Unity desktop.

From years I have download some netbook edition linux releases and test them on virtual machine and live mode. None of them give me any pleasure of using Gnome. Yes, I don't owe any Netbook computer. But I did not feel problem to understand Unity. I download and tried various netbook based linux distributions like 'Moblin', 'EasyPeasy', 'Meego', 'Ubuntu netbook remix', 'Jolycloud' etc. None of them satisfy me in any way. Though they all are like Unity2d but the main reason is the desktop usability. I like to keep my desktop clean. I always add less shortcut on my desktop. This is my common habit since windows 95. And the boring thing is on Unity desktop or populer netbook OS desktops are full of icon (application link shortcut) on desktop area. Sometimes it is hard for me to find any current downloaded pdf file which is saved on desktop. Even on some OS I can not access desktop by mouse. I can't touch any file which is saved recently on desktop. On Unity a very disturbing thing is left side pane. This is quite extra width then Gnome bottom (or top) panel. So it takes more space. I don't understand why Ubuntu developers don't understand this kind of simple thing. If they like to add regular using application links in-front of hand then they could use drawer like thing. It should have a hide button, so I can use more space when drawing a picture and I need larger area.

There are another main reason not to download or taste Ubuntu 11.04. I read many forum/ blog post/ mailing lists mail that Unity is quite modern hardware hungry. I have not much ability to buy a newer hardware.

I know Ubuntu developers will not understand money weakness of me or me like users. Because their target is not to make a lighter linux. There are many other option for lighter hardware user. They should use Light Linux not Ubuntu main distribution/ addition. They can use Lubuntu or Peppermint or AntiX or any LXDE based operating system.

I have install LXDE on Ubuntu 10.10. LXDE stands for 'Lightweight X Desktop Environment. This desktop environment is faster then Gnome and KDE desktop. It can run on older machines or on low end/ older hardware based computer. It has many difference then other desktop. Very speedy. Although development is on going process, many operating system publish their releases using LXDE. I use Lubuntu and Peppermint os many times and fall in love. Day by day this little desktop environment grub attention of many distro.

If you tended to test LXDE then know some little information first.
  • At least 47 new packages need to download.
  • It will take only 14.7 MB to download.
  • When you install, it will take 43.7 MB of extra space.
LXDE on Ubuntu DesktopLXDE Desktop.

If you really like to try LXDE. Then use Synaptic Package Manager or Ubuntu Software Center. Run any of them and search with keyword "LXDE". Select all dependencies to download. Your new lightweight desktop environment depends on these dependencies to work properly.

lxde available on ubuntu synaptic package manager lxde available on ubuntu synaptic package manager. You can install it from here.

Install Lxde using ubuntu software centerYou can install Lxde using ubuntu software center. I use synaptic to install. After completing install, I feel some curious to check ubuntu software center. I discovered that I did not install 'Task Manager'. So I install this application from USC.

install lxde task manager later from ubuntuI install LXDE task manager later from ubuntu. This is very easy now.
After completing download and install logout your computer and sellect LXDE session from the popup menu on bottom bar.

When I get a first jump on LXDE, I really surprise to see a huge number of software installed. Then I realise that Gnome desktop applications are available on this session too.

User switcher applet crashed, deleted in Ubuntu

Ubuntu User switcher applet crashed, deletedI don't know why it happened to me. I am still in Ubuntu 10.04. Last time when I start my machine, after desktop appear this message showing its nose to me. It says:
The panel encountered a problem while loading "QAFIID:GNOME_FastUserSwitchApplet".
I delete it. So 'Me Menu' also disappear from my Ubuntu machine. I thought deleting a crashed application is better. Later, I have searched my Ubuntu system and even in Google but failed to recover/ reinstall it. I did not find the way to get it back anywhere. I found this page by Google search result, but there is no any solution or download for Ubuntu 10.04.

Tor: defend network threatens

0
As the official website says Tor defend against a form of network surveillance that threatens personal freedom and privacy. If your activities look confidential business and need to keep security, want to analys traffic then Tor is perfect tool for you.
Tor internet securityMany kind or internet users use Tor to protect their privacy. Tor can help you stay safe online.
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.
This valuable software is also available in Linux too. Also available for Mac and Windows.

But Tor is not a magical thing, which protect you automatically. If you just install it and do nothing then Tor can not do anything. You need to configure some information to work it properly. There is a read first section in download page. That means you should read it before download Tor.

Warning: Want Tor to really work?

...then please don't just install it and go on. You need to change some of your habits, and reconfigure your software! Tor by itself is NOT all you need to maintain your anonymity. There are several major pitfalls to watch out for:

  1. Tor only protects Internet applications that are configured to send their traffic through Tor — it doesn't magically anonymize all your traffic just because you install it. We recommend you use Firefox with the Torbutton extension.
  2. Torbutton blocks browser plugins such as Java, Flash, ActiveX, RealPlayer, Quicktime, Adobe's PDF plugin, and others: they can be manipulated into revealing your IP address. For example, that means Youtube is disabled. If you really need your Youtube, you can reconfigure Torbutton to allow it; but be aware that you're opening yourself up to potential attack. Also, extensions like Google toolbar look up more information about the websites you type in: they may bypass Tor and/or broadcast sensitive information. Some people prefer using two browsers (one for Tor, one for unsafe browsing).
  3. Beware of cookies: if you ever browse without Tor and a site gives you a cookie, that cookie could identify you even when you start using Tor again. Torbutton tries to handle your cookies safely. CookieCuller can help protect any cookies you do not want to lose.
  4. Tor anonymizes the origin of your traffic, and it encrypts everything between you and the Tor network and everything inside the Tor network, but it can't encrypt your traffic between the Tor network and its final destination. If you are communicating sensitive information, you should use as much care as you would on the normal scary Internet — use HTTPS or other end-to-end encryption and authentication.
  5. While Tor blocks attackers on your local network from discovering or influencing your destination, it opens new risks: malicious or misconfigured Tor exit nodes can send you the wrong page, or even send you embedded Java applets disguised as domains you trust. Be careful opening documents or applications you download through Tor, unless you've verified their integrity.
There are many people and company around world use Tor to protect themself. International Broadcasting Bureau (http://www.ibb.gov/), Reporters without borders (http://www.rsf.org/) using it. Militaries, Journalists, Business person, Bloggers, Law enforce officers use Tor. Read 'Who Use Tor' page for details.

To download Tor visit this Download page.
For various kind of Linux installer please visit Download Unix

var d2 = new Date();
var endtime = d2.getTime(); //Get the end time
//Find the difference between the start and end times
var totaltime = (endtime - starttime)/1000;
//Round 2 decimal places
var result = Math.round(totaltime*100)/100;
//Output results to a "P" element

Best free zip-archive tool in the world

0
I just got a proof of this question: Which is the best zip tool.

If anybody search for the best archiver, compression utility or zip tool for Ubuntu linux or windows, he or she must be point to only one famous and most popular archiver in the world, the 7zip. You do not need to believe my word. Just search google or yahoo or bing or any other engine with any compression, zip, archiver type keyword and get the result. If you do not use any keyword like '7zip', '7z' in search field, though you will get the first result positioned only for 7-Zip. I know this information and use 7zip for some years both on windows and ubuntu. Today I got a proof of 7zip's great performance.
us afghan war document folderFolder sizeAfghan War Diary 2004-2010' from Wikileaks. This giant archive is full of huge hidden documents. Afghan War Diary 2004-2010 folder contain 88,095 items, and weight totaling 3.5 GB.

Here is some mathematic:
Wikileaks sharing this file as 7z format. File size 75 MB. (http://leakmirror.wikileaks.org/file/straw-glass-and-bottle/afg-war-diary.html.7z) My 'downloader for x' showing the size is 78168057 byte. After extracting this file it took 3.5 GB space in your harddisk. I compress this folder as zip format. And found that this zip file weight 841.2 MB (882047410 bytes). What a difference between the compression rate of 7z and zip format. Whares 7z own only 75 MB but zip format take 841.2 MB.Afghan us war 2004-2010 documents zip fileWhen I understand the differences between zip format compression and 7z format compression. I did not take seconds to make the decision that: Which is the best free compression tool in the world? My vote must go to 7zip software, a powerful compression utility.

Use Global Menu on Ubuntu 10.04

0
Ubuntu 10.10 netbook global menuRecently Mark Shuttleworth announce a new feature for Ubuntu 10.10 version. It will appear in only on netbook version. This feature won't be available on desktop version. Name of this new feature is "Global Menu".

Mark shuttleworth said on his blog:
We’re going to put the menu in the panel on the netbook edition of Ubuntu, and not on the desktop edition, because that’s where the screen real-estate is most precious. There are outstanding questions about the usability of a panel-hosted menu on much larger screens, where the window and the menu could be very far apart. Those questions are greatly diminished in the netbook environment, by definition.

Also, the netbook edition has a reduced application load. That will reduce the number of applications we need to get this working on.

However, it will be straightforward to use this on your desktop too, if you want, and we’d encourage people to try with that configuration. The more testing we have early on, the better we’ll understand how it works with different applications. It will be easy to add to the standard desktop panel for people who want to try it out, or prefer to work that way.
On this blogpost Mark explain everything about this 'Netbook Global Menu". He just want to make it clear that why this kind of menu is need on netbooks. Netbook computer has a very limited vertical size on screen. Standard is 1024×600. There is no problem about widh but vertical space is too short that developer need to think more. At last the confirm a solution. They add a 'Global Menu'.

Global Menu is a kind of Mac OS X like globally-shared menu bar. Which will use for applications launched in desktop session. This is currently only available for Gnome.

Though this 'Global menu' is only for netbooks and will release in Ubuntu 10.10 version, you can start to use it right now.

First add the repository in you system with this command in terminal
sudo add-apt-repository ppa:globalmenu-team/ppa
Than apply the command below for Karmic and Lucid
sudo apt-get update && sudo apt-get install gnome-globalmenu
Remember that this Global Menu is not that which Mark shuttlworth said in his blogpost. This application already running and developing by Ubuntu community. It's name is Gnome2 Global Manu. It has some limitation.
  • It will not work in Firefox and Open Office
  • It will not display window title and controls.

How to Install Newer onto Older

0
Ubuntu 10.04 LTS final release is going to publish tomorrow. I know you all Linux/ Ubuntu lovers are waiting for that special moment. After announcement every open source and ubuntu enthusiast will download the newer version and install in their system. I will do same, but thinking the correct method. My asking to myself is 'how do I install newer ubuntu?' I am using Ubuntu 9.10 now. My home folder is full of valuable data. I don't want to lose them all. I know partitioning in Linux. But as a new user I don't know how to install newer Ubuntu 10.04 onto older Ubuntu 9.10? I know that their is a fine solution on this topic. But for last days I cannot remember that way. Some minutes ago I found the way that I can erase older ubuntu but my home folder will be safe.

The solution: At a partitioning stage, I will select 'manual partition' then select root to my older root, swap to older swap and home to the older home folder. I will select 'format' for 'root' and 'swap' partion, not in 'home' partition.

Then newer ubuntu will delete all the information of older ubuntu but 'home' folder will stay intact and safe. On install process installer will not touch 'home' partition because I did not give permission to delete files from it. I just say installer to use it as a home folder. I think I am right. Do you have any suggestion?

I have changed my contact form

0
wufoo email me contact formAfter starting this blog, I have add a contact form in this page. I used 'Wufoo" to create a contact form. But today I have changed my provider.

Last day one of my friend said that he just send a mail to me and I did not answer her yet. She is very angry to me for my not reply. I am astonised. What is she said? I thought did she really send me any mail using my blog's contact form? I checked that form by myself sending a fake email. But alas! She is write and I am wrong. 'Wufoo' did not send me any mail. That means 'wufoo' contact form is not working? Why? What's the reason? Is it for that I am a free user? If so, then they did not done any fare job to me. Because I did not found any such kind information that they will not send mail to me if I am a free user.

I log on to 'wufoo' site and did not found any mail if they want free users to log in to read mails. No. There was no any mail waiting for me. Even there is no any options or help page which describe my problem.

So, I decided to through out 'wufoo' from my site. Actually 'wufoo' has many nice feature and colorful control panel. I liked them all. And want to write a post about them. But they done unfair to me. They don't like free users. They don't want free blogger to use their form. They should write it clearly in bold text in their website. Even they have not any trial period for their free users.

Today, I go to http://www.emailmeform.com site and made a Email Me form for my blog. I add it into my blogs Contact Page and working nice. You may check it sending me a mail.

I am very happy with the service of 'emailmeform'. I will write a post about them as soon as possible.

Nested Labels at Gmail inboxGmail blog has published and announcement. The said that nested label feature is now enebled in Gmail. Here is a snapshot at the left side. How to get it in Gmail inbox? If you like to use it, go to the Gmail Labs tab under Settings, and look for "Nested Labels". Now enable it and click "Save."

Now it is time to create some label. Name label with slashes (/) to make it the child of another. As example, let's say you wanted to create a simple hierarchy with a "Home" label, and inside it a "Members" and a "Jobs" label. Just create three labels with the following names:

Home
Home/Members
Home/Jobs

If you want, you can then create "Home/Members/Kids," "Home/Pets," etc.
In Gmail blog official said that :
You can create complex hierarchies of labels if that's the way you like to organize your mail, and you can expand/collapse labels to save space. You'll always be able to tell whether a given label contains unread messages in its collapsed child labels by looking at whether it's bold or not.
