Manage & share your calendar and tasks using Chandler
2008-06-06 21:24:00
As many employees now work from home or outside the main office, we need to find new ways of keeping everyone aware of company-wide meetings, events, important tasks and even shared contacts. If your company uses multiple operating systems, then you’ll know it’s hard to find collaboration software that will enable you to share information across different browsers and systems. Chandler Project 0.7.1 is a desktop and server application that enables you to store your calendar and task information and then share with other users (who you allow access to your data). If you have a large organisation, you could install the server technology. However, Chandler Project also enable you to have a free online account, using their server to share your calendar.

Add a domain name to your Windows Live services
2008-06-06 21:23:00
Microsoft’s Windows Live service contains a myriad of online and offline tools that enable you to check your email, manage and share your photos, host and store data online and much more. They’ve now gone much further and added the facility for you to point a domain name to the services, so instead of using live.com or live.co.uk, you can now use yourdomain.co.uk and your Windows Live -based email will go through the Live service, even though it looks like you’re hosting your own email, site and so on. If you fancy moving your domain over to the Live services and hosting your business data and other information, online, why not consider the Windows Live Community Builder? You can choose a brand new domain, rather than moving across your business domain, if you prefer.

Create and manage your eBay auctions using iSale 4
2008-06-06 21:21:00
Far from being an online auction house, eBay is almost an online shopping portal for people wanting to buy their goods. It’s fairly easy to make money through eBay, but more difficult to get noticed and, if you start from scratch with no feedback, you’ll need some eye-catching professional auctions so that you look like you’ve bothered to make the effort. Here lies the problem. Most eBay sellers simply use the standard browser-based tools to create their auctions and do not know that you can manage the visuals that make up your auction, through another specialised application. iSale 4.4 is a tool designed for the Mac OS that enables you to pick a template for your auction then configure just about every aspect of this template. If you’re a powerseller, you can use an external image storage site such as Picasa to maintain your images, whilst keeping a standard set of sales conditions for all your auctions. You can also monitor and maintain your auctions once t...

Google to turn Google Mail storage into GDrive?
2008-06-06 21:20:00
We’ve been speculating for months now, but it looks like Google are finally about to release their storage depot for storing or backing up your files online. If you have a Google Mail account, you’re able to store nearly 3GB worth of email, for free. If you require more space, you can  purchase more. You can also store and share your photos using the Picasa Web Albums and, again, you have the option to purchase additional space. There are ways of storing files through your Google account, without waiting for the much-dubbed ‘GDrive’ from Google. The unofficial GMail Drive 1.0.12 will enable you to take your free GMail account and turn the storage space in to an area where you can store files. However, as it’s unofficial, it could be stopped at any time, so perhaps isn’t the wisest choice for relying on storing your important data.

Print your documents on any printer connected to the Internet
2008-06-06 21:19:00
With later editions of Windows or Mac OS X, you have the capability of logging in to a computer, wherever it is connected to the Internet , as long as you know the IP address and the login/password (oh, and remote access is enabled). If you can log on to a remote computer or use a remote computer as a home-based server, there’s no reason why you shouldn’t be able to share your printer with another Internet user. This means you could print your work on a printer, whether it is connected in a building down the road or at the other side of the world. Print erAnywhere 1.08 is a free tool that will enable you to share your printer on your Internet connection. If you have a static IP, your details will never change, so if you have an expensive colour laser printer, you could even set yourself up as a semi-commercial publishing house and enable access to your printer to those with your details.

Create your own professional website using Web Design templates
2008-06-06 21:17:00
Create your own professional website using Web Design templates Most companies only really want to put basic information online and keep it updated. Information about the company, directions, contact details, a little history, some downloads and perhaps images of various products and so on. The snag is, getting this professional designed and implemented can take ages, particularly if you want some kind of CMS so employees can make changes - without affecting the site structure. The alternative is to design your own basic site, although getting started is the hardest part. Open Source Web Design templates is a developer-resources site full of web templates that can be used to put up a basic homepage through to a commercial web space. You can search through the designs, view the most popular and more. You can also make your own derivative, if you want to change the colours, fonts and other elements that make up the site template.

Import, edit and export your photos online, using Picnik
2008-06-06 21:15:00
There are times when you find a genuinely useful application which you know might prove useful in the future. For instance, I’ve often wondered if I could edit and manage this Junky blog from a PDA or similar portable device. Writing the blog would be relatively easy, preparing and editing the photos would not be so easy. What would be required is a portable or online image editor that would enable me to grab a photo from a collection (on or offline), edit as required and then export in the right size and format. Picnik is an impressive online-only image editor that does exactly this. The basic version is free, too, so you can do all the image editing and management you require, without having to upgrade. If you want to do more with your photos, there is a premium edition. Picnik enables you to grab photos from an online photo collection, such as Flickr, Picasa web albums or even a social networking site such as Facebook. Picnik link.

Design and build an impressive website using Doodlekit
2008-06-06 21:14:00
We’d all like our own homepage on the Internet. You can use this for writing your own personal blog, displaying your latest holiday photos or making files available to download to your friends and family. You can even hide areas on your site so only certain people have access. The snag is, how do you get this website online? You may need hosting, you may have free web space. You’ll also need some basic web design and image editing skills. One option is to use a tool such as the superb Rapidweaver. The other option is to get someone to do the site for you. Doodlekit is a free online web building kit that ships with the templates you require to create your pages, with free hosting. You can make minor changes to the style and colours of your site, but Doodlekit will display ads on your site where they will make revenue (when someone clicks on the ads). You can choose to upgrade to a paid-for monthly subscription, however.

Store and access your serial codes online with Keyfiler
2008-06-06 21:13:00
You know the score, you buy your software and then receive a serial code by email. Two years later, you want to reinstall this software and can’t find the original email. Worse, you can’t find the order number so you can’t login to the original site to find your code. Software suppliers might help - as they don’t want a disgruntled customer - but in most instances their orders are accepted by a specialist online e-commerce company such as Digital River. Keyfiler is an online-only system that will enable you to store your software serial codes online, in a unique database designed for this purpose. You can also store your web usernames, passwords and other information. You can then export the data to your computer if you lose it in future. However, you need to ask whether you can trust a third-party site to securely store and manage your personal software serial codes? Keyfiler online link.

Run OpenOffice from any location, over the Internet
2008-06-06 21:11:00
With employees having to attend meetings outside the office, work across different buildings and even the odd day from home, we’re having to move around our data, bookmarks, document templates and other tools. We could use the Internet to back up and store our data and then install various applications on a USB stick and then take that with us on the road. However, there are other options. For instance, Ulteo have introduced a system so you can use OpenOffice from the Internet, rather than having to install this on a portable device. The new system ships with 1GB of storage space and full access to the OpenOffice applications. You can open and save documents, edit Excel files and more. The only snag is, it’s a bit slow, but that’s partly due to the publicity that the new service has received. Ulteo OpenOffice online link.

Create and send innovative web-based party invites
2008-06-06 21:08:00
We bet you bought a DTP with the sole purpose of using it to create an invite, whether this was a wedding, birthday or one-off party. Once you get designing your invite, you’ll quickly realise that it’s much harder than you expected, especially when you try and find graphics to make up your document. It would be far easier if you could do the whole thing over the Internet as most of your friends and family have an Internet connection. Evite is a cool web-based invite and greeting card system that will enable you to take a pre-designed card template, add your details, party invite and attendees and then simply email address to the recipient. They’ll see a professional animated graphic, along with the invite. The only snag is, it didn’t seem to work properly with the latest version of Firefox and assumes you’re based in the States, although it should work for different territories. Evite link.

Chat and keep in contact on the road, with Jooce
2008-06-06 21:07:00
We’ve spent months talking about portability, with the facility to take portable apps on the road and keep your private data stored on a portable USB stick. However, one site has gone much further than this and has decided to create a complete personal desktop that you can log in and access, from any computer and any location. Jooce is a portable personal desktop designed around keeping in contact and chatting with your online friends. In the same way you’d log in to your web-based email, you can log in to your own desktop and use this desktop to store your music, photos and chat online. Jooce isn’t the fastest operating system in the world and it’s not Windows-based, but it contains all the tools you might require to keep in contact, chat and store media files. In future, you’ll probably see it moving forward as a fully-fledged desktop. Jooce link.

Migrate your Outlook email to your Gmail account
2008-06-06 21:07:00
Although most of us still use an offline client to access our email, one key reason for this is that we often have multiple accounts and archived email, contact information and more. If you’ve not heard from someone for a while, quickly search for their last email and drop them a quick note. It’s all very easy to do this from within your existing email client. However, now Gmail offers over 5GB worth of storage for hosting your email, there’s no reason why you couldn’t migrate some of your Outlook -based email across to your online account. To do this, you’ll need to make sure you strip away some of the largest email. You could temporarily store these in a separate folder (away from your inbox) so they are not copied across. Turn on IMAP support within Gmail and then follow these instructions. Move Outlook email to Gmail instructions.

Provide files to other net users with HTTP File Server
2008-06-06 21:05:00
When providing files to other Internet users, we often try and email large attachments and then wonder why the recipient hasn’t receive your email. The other option is through a chat-client, which will give you a direct link to the other user. However, you have to sit there and manually send each file and it’s not the easiest way to get large photos or files to other users. You could put them on your homepage, but then you’ll be restricted by bandwidth limitations. HTTP File Server 2.2 is a tool that you can use on your PC to provide files to other Internet users, in the same manner as your own homepage. You could even assign a domain name to your computer, so that you give our yourname.com and other users will see the files listed on your site. They can then download at their convenience directly from your PC. HTTP File Server link.

Linux or Windows?
2008-03-09 14:03:00
It is true that most people in the world are using Windows . But there is a doubt: “Is it the best OS for PCs?”. Here is a brief description regarding Linux vs. Windows. GUI (Graphical User Interfaces) - Both Windows and Linux provide GUIs and both are seem to be fairly ok. But there is an advantage in Linux; many GUIs (Gnome, KDE, etc) are available. Windows only comes with its own one and only GUI. There are some external software to change the look of the theme. But those are third party products and take up too much memory and slow down your computer. Shell / Dos prompt - The shell in Linux is very powerful. You can do almost everything in the shell. But the Dos prompt’s scope is limited to a small area (Almost only file handling!). Cost - Linux is almost free and Windows is around $200 - $300. But when you consider running Linux on a business environment, you may have to hire some Linux technicians, who might be more costly than the Windows techno craps. Live CDs - Windo...
What is the best hosting plan for you?
2008-03-09 13:59:00
Ever wanted to have your own site? Then you might have a nice experience with thousands of hosting packages…… There are lot of them, and not sure what to choose? Then read this. When we consider about hosting, there are several major facts you have to consider: storage, transfer rate and of course **cost**. Let’s look at them one by one. Storage - Most of the personal sites are smaller than 5 MB. And if your site is larger than this, the best option would be optimizing your graphics. There are several advantages on that. The major advantage would be, your site loads fast and it is cost effective. So, in that case there is no need to go for a big storage plan. Take only much as you want! Monthly Transfer Rate- This is a major fact that most people mess around. There are some hosting plans which provide you about 600 MB storage and 1GB monthly transfer rate. What it means is, your web site only allows you to do transactions up to 1 GB. For example, you have a big file about 500 ...

Freeze the world and sweep the mines.

Minesweeper, a really simple nice game. Probably one and only bug free Microsoft software. I think, all of you have played Microsoft minesweeper at least once. Basic idea is to recognize the mined squares. When, I was playing this game, I wanted to **cheat**. But how ? Not like, downloading simple cheat codes/ trainers and running them. I need another way. A way which I can have fun. There were two ways. The easier way was, changing the “best times” in the registry. It was fairly simple. You just have to change the registry values. Then, the next method was, changing the code. But the Microsoft is close sourced. The game is compiled. How can I change the code? Confused? I’ll show you how. So, every time you write a code in c++/vb/pascal… and compile it, the compiler converts it into the assembler code, then to the machine code. The assembler code and machine code is very similar. Conversions between those two languages are simple process although it is almost impossible to c...

Cracking the passwords
2008-03-07 11:50:00
Admin password, the dream of everyone. Specially, when you are in an environment where you are not the system administrator. Today, what I’m going to show you is how to take Windows Administrator passwords. You might have even noticed, if we can find out where windows stores the password, we can just look at it. But unfortunately, it is not that easy. Windows stores the passwords in the WindowsSystem32ConfigSAM file. But windows prevent you from accessing that file. So, the answer is LINUX. Take a Knoppix CD, put it into your CDROM and restart the machine. Make sure your first boot device is CD-Rom. Then, it’ll boot into the Linux. Then the best option would be a USB pen. Just mount it and copy the SAM file into it. And make sure you also copy the WindowsSystem3ConfigSystem file. Then, restart again, you need Windows now. Now you have to take a key called syskey from the system file. There are some windows utilities to do that, but I can’t remember the names. Anyway, onc...

Arp Poisoning
2008-03-07 11:49:00
When you guys wants to do packet sniffing what do you do? Just running a packet sniffer? That’ll work if your network is connected using a hub. Not in a switched enviroment. So, the solution is arp poisoning. Arp Poisoning, one great method of hacking. The basic idea behind arp poisoning is changing the packet destination by fooling the computer. In a local area network the computers are uniqly identifical by the MAC address and IP address. The top level software communicate using the IP addresses. So, when a software wants to connect to another machine, it creates a data packet and put the destination IP address. Then, the kernel takes the packet. The kernel have a table called ARP table which have information about ip address againts the mac addresses. So, the kernel looks at the ARP table and then takes the relevent MAC address. If MAC address is not available in the table, it sends an arp request saying “Hey, xxx.xxx.xxx.xxx, send me your MAC address”. So, the other comput...
Social Engineering
2008-03-07 11:48:00
One day, in an afternoon, when you are relaxing in your home, you get a call from HSBC and they tell you they are rechecking credit cards. “Could you please tell me, your credit card number?”. Just without thinking much, most probably what you’ll do is tell it. And your personal details, etc. So, next month when the bill comes, you know someone has illegally used your credit card. Basically, that’s social engineering; Gathering information by talking to the people. This is easier than hacking, and probably more effective. Because in a computer system, system admin can patch the vulnerable products but there is no patch for human stupidity. Just wanted to tell you, “Beware of Social Engineers”.

FreeCell - Allow any move
2008-03-07 11:48:00
“That move is not allowed” - most probally you have got this message several times when you are playing freecell. This message is bit of a headache. I wanted get rid of it. With the great help of W32Dasm, it was pretty easy. The first step was disassembling the game. Then, I searched through the code for “That move….”. It only appeared only once which makes our job much easier. backtrack, backtrack, backtrack, it was really easy. Then I was able to find out a jump : “jbe 01003C2B” at offset 2F7C. Changing those into ‘nop’s will allow you to make any move except the moves on top bars. So, I was going around here and there in the code and managed to change the top bar. Since it is 3:23 AM, I’m not going to explain how to do it. If you want to change the top bars, you can apply the same theory. It is also changing few jumps. Hint : Try to use debugging feature of W32DASM.

LAMP, a commonly used web development combination. Linux, Apache, MySql and PHP. Since, the language, PHP is designed for web developing, the language is very simple and anyone can learn it easily. And combining it with MySQL allows you to build very powerfull web sites. There is one dangerous mistake that some people may do. Directly passing the values from the user to the database. How it could be so dangerous? I’ll show you an example. Let’s say you have a login form and line like this in the action page. $result=mysql_query(”SELECT * FROM users WHERE username=’”.$_POST[’username’]. ‘ AND pwd=’”.$_POST[’password’].”‘ ) ; Normally, The script will add the values from the user into the sql query. So, It will be something like : SELECT * FROM users WHERE username=’sandaruwan’ AND pwd=’secret’ There is nothing wrong with it. But let’s say, Instead of typing my username, if i type something like : sandaruwan’# What would happen? The script w...

How to hack gmail / yahoo / hotmail
2008-03-07 10:31:00
Thousands of people searches through the internet for the above topic, and apparently they come up with quite nice articles which explains how to hack. Most of those are sending an email to a specific email address of the service provider which is a system account. What you have to do is, send an email from your account with your password and also add the email account to be hacked into it. It’s very easy, they give you the format of the email, you just have to insert the two values and send the email to the system account. And just after you send the email, the system account logs into your account and then do some bullshit(this changes from article to article) and send back the password of other person. Pretty cool isn’t it? This method is really simple. As I mentioned before, this technique is called social engineering. Once you sent your password, it’s a hack! They have used social engineering to get into your account. There is one thing you need to keep in mind before sea...

Penetration Testing
2008-03-01 16:40:00
Now that the components of the target network have been identified, the team needs to determine ways to gain access to them. Because it is an overt test, the team can sacrifice secrecy for efficiency and use automated vulnerability scanners, such as the open-sourced Nessus (used by system administrators to search for weaknesses in their systems), to perform a quick sweep of the target network rather than having to manually probe for common vulnerabilities. Nessus exposes various weaknesses on the target systems. For example, it reveals a buffer overflow in one system (a common attack in which a large number of characters, such as a very long log-in name, can crash a program and allow an intruder entry). It also finds a flaw in Pine’s Sendmail application to the IIS Unicode Folder. This flaw, called the Web Server Folder Traversal vulnerability, is one of the most common Windows systems vulnerabilities. Based on past successes with the IIS Unicode vulnerability, th...

Types of Software Testings
2008-03-01 16:38:00
Black Box Testing– the testing team has no insider knowledge of the target environment. As such, the team must spend a considerable amount of time discovering such information, if any can be found. Crystal Box Testing– the team is given inside information about the company’s network and may even work with insiders who have privileged information, such as the configuration of the network or the types of hardware and software in use Overt Testing– In an overt test, system administrators know of the test and can watch the red team in action. Overt testing is less realistic, provides valuable lessons for the organization’s security members, as they are able to watch the attack in progress.  Covert Testing–   Most employees are unaware that the organization is being tested. It is more realistic than an overt one and can be used to measure the effectiveness and responsiveness of the defenses. However, such tests are generally longer in durat...
