PeaZip & 7-Zip…Both are open source file and archive manager. Both are cross platform, available as portable and can be used to compress or extract files of various types.
PeaZip
1. a) Packing : 7Z, ARC, BZ2, GZ, PAQ/LPAQ, PEA, QUAD/BALZ, TAR, UPX, ZIP;
b) Unpacking only: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF and many more archive types (79 file extensions supported, see full list)
2. Split/join files
3. AE256 encryption
4. Generate random passwords
5. Secure file deletion
6. Checksum and hash files
And more. Find out more from the official website.
7-Zip Main Features:
1. High compression ratio in new 7z format with LZMA compression
2. Supported formats:
a. Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
b. Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB and NSIS
3. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
4. Strong AES-256 encryption in 7z and ZIP formats
5. Self-extracting capability for 7z format
6. Integration with Windows Shell
7. Powerful File Manager
8. Powerful command line version
9. Plugin for FAR Manager
10. Localizations for 69 languages
Find out more from their official website.
7-zip is smaller compared to Peazip but Peazip is more beautiful looking. If you would like to change how 7-zip looks and you are willing to learn by searching on google, that’s good but if you’re the kind that likes to use after installing without any configuration and you like beauty, go for Peazip. 7-zip would be good on old computers and slow computers.

Linux on slow computers Episode 2
August 20, 2008 at 6:41 am | In Reviews | 2 CommentsTags: light desktop, linux, linux light, Linux on slow computers, old computer, old hardware, open source, Pentium 3, Pentium III, reuse, Vector Linux, xfce, xubuntu
The 2nd experiment that I did was install Xubuntu 8.04 Hardy Heron on my Pentium 3 256MB Ram. Comparatively to Vector Linux Standard Edition(XFCE), I liked Xubuntu better as to add/install softwares were easier and spiced up with graphics compared to Vector Linux which looked plain and old.
Speed was almost the same at first, but after I’ve downloaded and installed the softwares I needed to run on the computer (eg. Open Office, Mplayer and so on), it was slightly slower compared to Vector Linux. That’s the price we pay for graphics I guess. Overall, I would choose Vector Linux as it was faster but wait…. when I installed Vector Linux on my computer, I logged in using a different desktop environment which was Fluxbox. It was way faster and not bad looking. It will be hard at first to get used to it, but I do enjoy the speed and the graphics are ok. It has the AWN kind of dock or a dock like MAC, not exactly the same but almost and it is fast not slow like AWN.
I guess the nest would be Linux Mint(fluxbox) and Fluxbuntu. Why? It’s because it is based on Ubuntu so that means it would be easier to handle compared to Slackware and others which most people don’t want to learn. If you’re more into technology then you should try out something harder like downloading debian, gentoo, slackware or any other major distros and start from the basics.

In this article I am going to provide you a simple and quick way to setup reliance data card on ubuntu hardy heron. Most of the tasks could be done with the script that I am attaching here.
1. Plugin Data Card
2. Download setup script from here. Open a terminal and run it as ” bash reliance_setup.sh “. It will ask for your data card connection number. Provide it when it does and press enter. The script will install gnome-ppp gui package, wvdial, and modify the necessary system files to setup permissions to dial the reliance connection using ppp.
3. Once set up, the script will launch gnome-ppp dialer. You need to provide following,
Username
Password (same as usrname. the connection number)
Phone Number : #777
4. Click on “Setup” option from the dialer window. From modem tab, click on “Detect” button which will automatically detect your usb modem in most cases. If not, you’ll have to choose it manually from the dropdown menu. Choose speed as 115200 from the drop down list.
5.
You could leave rest of the options as it is for now. Close the setup window and click on “Connect”. You are all ready to rock. A connection window will appear, from which you could click on “Log” to see what is happening while connection is progress.

July 29, 2008 at 11:20 pm | In Multimedia, Reviews, ubuntu | Leave a CommentTags: GNU, linux, miro, Multimedia, news, offline, open source, review, technology, videos, youtube
Are you tired of waiting till your favorite yououtube video stream is being buffered to avoid jitters? Are you looking for an application to save youtube videos offline and watch them at your convenience
later? Do you want to save multiple parts of a video and watch it as a whole in one go? …. Try Miro.
Miro is an application which turns your computer into an internet TV video player. It has a concept of channels whereas viewers could browse through thousands of channels available and subscripbe to them and receive regular feeds downloaded at your desktop, some of the most popular being ‘National Geographic Video Shorts’, Discovery Channels Video Podcasts, Cartoons, Spanish Learning Channel etc.
Here are few interesting features available with Miro:
1. Watch YouTube Videos: One can search, download and watch YouTube videos and videos from maany more video streaming sites such as Google Videos, Yahoo Videos, Blogdigger, Blip.tv, DailyMotion. The application actually downloads the videos to harddisk, making it available to be watched offline. By default the video expires in 5 days, which can be changed with option to store it permanently on the drive.
2. Video Player: Miro also acts as a video player for the internet videos. It uses embedded player such as gstreamer, xine in linux and vlc on windows, and quicktime on Mac to play the videos. One could
actually watch videos in fullscreen mode, which apparently looks better than that watching it on youtube. And users could play videos, which generally come in the parts, as if it is a single video.
3. Cross Platform: Miro is a Open Source Software, released under GPL License, and is avaialble on Linux, Windows, and Mac Operating Systems.
4. Widely Supported Formats: Miro supports a wide range of video formats including MPEG, Quicktime, AVI, H,264, Divx, Windows Media, Flash Video(Youtube Videos) and many more.
5. Channels and Automatic Video Downloads: Miro comes with an in built channel guide, which users can brows through and select thier favourite channels. Once added, users can configure miro to download videos automatically as and when added.
6. Podcasts Compatible: You could add your podcasts that you have been downloading automatically with itunes so far, to Miro as a channel. Once added, all new podcasts can be downloaded automatically.
7. Share: Users could search videos, watch them and share with friends using social sites such as del.icio, digg, reddit etc.
Even though its released as a beta, overall, Miro is a wonderful app to have on your desktop.
Linux on slow computer Episode 1
July 12, 2008 at 10:52 pm | In Reviews | 1 CommentTags: light desktop, linux, linux light, Linux on slow computers, old computer, old hardware, open source, Pentium 3, Pentium III, reuse, Vector Linux, xfce
Well, I’m back at home now and I’m on holidays so I’m too free and decided to look out for old computers to try out linux and I found a Pentium III 800 MHZ 256MB Ram with 10GB hard disk (IDE).
I tried out Vector Linux (STD) on it. For those who don’t have a clue about vector linux, you can visit www.vectorlinux.com, it is based on Slackware, installation is in text mode and it is not that easy for a beginner (let me remind you to read the manual 1st before you try installing), XFCE interface, uses XMMS to play music, MPlayer and Xine to play videos and I must say they changed the skins and made it as default which is pretty impressive as they definately look better than downloading it yoursef with very ugly skin as default for MPlayer. I’ve never liked MPlayer because of the looks. I don’t need a very good looking player but at least lookable.
As for internet browsers, it comes with Firefox, Opera and Seamonkey. Well I sticked with Opera as it was the fastest loadin, Pidgin to connect to MSN, AIM, ICQ, Yahoo, GoogleTalk and so on. They did a good job in creating VASM (Vector Linux’s Administration and System Menu) – a graphical tool which helps configure systems and network adminitrations. K3B, Xfburn is the burning tools, ripperX and X264 is the audio and video ripper. It comes with Adobe Reader 8, Abiword(replacement for MS Word), Gnumeric Spreadsheet, Scribus and a calculator.
It comes with one of my favourite games as well, Mega Mario. It was quite good. It was running fast, graphical boot (I didn’t get that with Ubuntu), it had the basic need mostly I would say. You could even make the panels and windows transparent(like Vista effect) and it didn’t become slow. I rather install this than have any Windows installed in it. Thanks to people that created it. There are few versions on Vector Linux, but I used the standard edition as it was the fastest available for my computer because I like speed. I could have installed the KDE version but I’m not a fan of KDE so i decided to install the XFCE instead. Thank you. Next I’ll try Xubuntu. Till then.

How to install Broadcom BCM94311MCG WiFi Card on OpenSuse 10.3 using NDISWrapper
May 18, 2008 at 3:25 pm | In Uncategorized | 1 CommentTags: bcm43xx, bcm94311mcg, driver, linux, ndiswrapper, open source, OpenSuse, technology, ubuntu, windows drivers, wireless
Here is a howto to install Broadcom wireless card drivers on opensuse 10.3 using ndiswrpper and windows drivers. I installed Broadcom Corporation BCM94311MCG wlan mini-PCI adapter on Compaq Presario 3611AU. The process of Installing windows drivers on linux using ndiswrapper is more or less same for most of the adapters.
- Windows Drivers : You need to download download windows drivers to get started with. Windows XP drivers are generally safe to be used with ndiswrapper. I downloaded xp drivers for broadcom adapter from hp/compaq site. ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36684.exe.
- Extract the windows driver exe using cabextract. cabextract sp36684.exe
- Install ndiswrapper package using yast. This should be straight forward.
- Unload the bcm43xx module. rmmod bcm43xx
- Load ndiswrapper using modprobe. modprobe ndiswrapper
- Load windows drivers extracted in step two. Load the .inf file using ndiswrapper. ndiswrapper -i *.inf
- Blacklist bcm43xx module, not to be loaded at boot. echo “blacklist bcm43xx” >> /etc/modules.d/blacklist
- Configure ndiswrapper to be loaded at the boot time.
