Email Extraction

I find it amusing when some people use fictitious email addresses during the registration process on this secure site but have absolutely no qualms in signing their names (and email addresses) to some online petition or forwarding to a string of people one of those endless office junk mails.

But why the fear? Why are people reluctant to leave their email addresses on public forums? The reason for this is very understandable, the fear of SPAMMERS. Email spamming refers to sending unsolicited emails to a list of email addresses. It may occur innocently when a reply is sent to a mailing list, by clicking REPLY ALL, instead of just replying to the sender of the mail or, more importantly, when unsolicited emails most often containing advertisements for services or products are sent to a list usually created by scanning forum postings or searching the Web for addresses through a process called Email Extraction.

Email extraction is a form of Web data extraction. It is the process of retrieving data in a structured format from varied, unstructured sources with the use of softwares called Email Extractors which are designed for extracting email addresses from online sources like the internet or offline from files located on local hard drives.

Trust me, the process of email extraction is surprisingly very easy. In just a few hours, you can retrieve tens of thousand of email addresses dropped carelessly on the web.


Weekly Review

Unique visits for last week stood at 1437, we thank those that made this happen.

This week, we are stepping up activities on the forum.

Come together and let’s share ideas. Who knows, you might even get a freebie while you are at it.


Is Symbian truly Dead?

There’s been so much talk about the impending demise of Nokia’s Symbian platform, the operating system powering almost all the phones in the Nokia range.

The Symbian operating has come in a lot of iterations over the years but the relevant ones today are;

SYMBIAN S40 – Introduced in 2002. It is regarded as the world’s most widely used mobile phone platform and is found in hundreds of millions of devices, mostly in low tier phones and a few mid-tier phones like the Nokia X3.

SYMBIAN S60v3 – Introduced in 2005. It is found in mid to top tier phones like the Nokia E series, N Series and C5.

SYMBIAN S60v5 – Introduced in 2008.Also found in mid to top tier phones like the Nokia N97, 5230, X6, C6 and 5800

SYMBIAN ^3 – To be debuted in Q3 2010 with the Nokia N8 smartphone. The OS is expected to feature better graphics, support multiple touch, better multimedia and multi tasking.


Portable Applications

It is common place in most offices to have administrative priviledges removed from end-user PCs. This is usually done to prevent unauthorised installation of softwares or hardwares on such PCs. Unauthorised software installation is usually a primary source of introduction of malicious softwares that may cripple a computer network.

This write-up may seem like a FOR-TECHIES-ONLY, a little patience please.

I had come across Portable softwares a number of times before now but i never really paid much attention to them. But on EYEBEEKAY’s insistence, i decided to surf the web to check out what it’s all about. Man, i sure have been missing a lot! I have decided to summarize my findings in this short write-up.

Portable applications or Portable apps, as they are commonly known, are not much different from your regular softwares. Wikipaedia defines a portable app as a computer software program that is able to run independently without the need to install files to the system it is run upon. They are commonly preinstalled on removable storage devices such as USB flash drive or CDs (For those have their USB ports locked down).

Almost any application can be made portable, some with greater difficulty while a few cannot because of their high dependence on system resources.Luckily, most basic softwares that we all use on a regular basis are portable.

Yeah, Portable, but why go portable?

– Bypass administrative level restriction. Use your regular softwares on any PC anytime, anywhere.
– Reduce the clogging up of your computer registry, a primary cause of system instability.It leaves a Zero, or near zero registry footprint.
– Have all your regular applications available for use on any PC, saving time on the installation of the same softwares on every PC you use.

So, how do we create portable apps? Well, there’s a little problem there. There are a few softwares that can be used to convert  applications to portable formats and VMWARE’s THINAPP is probably the best to achieve this but with a stunning and shocking price tag of about US$5000, God Have Mercy! Another alternative is Xenocode ($1599). Make your choice.

For now, we will limit ourselves to ready-made portable apps. A very good repository can be found on Portableapps. Others include Techsupportalert, Appstogo and Portablefreeware

Contributions anyone? Eyebeekay, you started this.


Blackberry Faces Ban

There are indications that there is going to be a ban on some blackberry services in the UAE effective October 11, 2010 because of the inability of authorities there to monitor blackberry’s encrypted services. Services affected include blackBerry email, messaging and web services . The UAE ban will also cover foreign travellers passing through Emirate airports. Saudi Arabia is likely to follow suit.

Unlike other smart phones – iPhone 4 or Nokia – whose services are handled by local wireless operators, BlackBerry doesn’t send emails over the internet. BlackBerry messages are first encrypted and securely stored on the smart phone and then sent out in encrypted manner through its own highly secure Network Operation Centre or server.

There is a possibility of a compromise before that date because of the level of business the company stands to lose, a move that may compromise on the existing level of security offered by this company.

We can only watch and see.


Ebook Readers

Ebooks and ebook readers are becoming increasingly popular these days, so much that only very few books or magazines are published without consideration for an ebook format version.

Ebook readers come on different software platforms and devices. Many come in form of  dedicated devices like Amazon’s KINDLE and Barnes & Nobles (B&N)’s NOOK. These happen to be the major players. Many also come in form of softwares ported for PCs and devices like smartphones, ipad, iphones,etc.

Ebooks files come in a lot of formats. Many of us are familiar with Adobe’s PDF, Microsoft’s DOC and maybe RTF formats.  There are an awful lot more than these with some of them being proprietary like the AZW format for the kindle and Zinio’s ZNO. For a better understanding of this, check out this write-up on Wikipaedia.

A number of companies offer top rate magazines and books for download on PCs. I can not say for sure how Zinio compares to its peers but I’ve actively subscribed to their services for about 3 yrs and it has been a satisfactory experience. However, companies like Amazon and B&N offer similar services and probably have a larger array of  books to offer.

For a number of reasons, i have not really been a strong fan of PC based ereaders;

– Reading from a PC for prolonged period causes eye strain mainly due to its backlight (applies to smartphones too).
– Your PC is not exactly very mobile.

Recently, i went shopping for an ebook reader for myself but like with a lot of people, making a choice could be a little confusing and difficult. I finally settled for ECTACO’s JETBOOK LITE based on the following considerations;

– It was about the cheapest when i got it for about $129.99.The darn thing fell to $99.99 about 3 months later!
– It supports the widest file formats, about twelve.
– It does not have any proprietary restrictions. I could even install some other 3rd party firmwares. Dare you to try that with a Kindle!
– Easy access to ebooks.

Virtualization Part 5 – Final Notes

With this write-up, we conclude our series on Virtualization.

To toggle between full screen and minimized screen in Virtualbox, you press the key combination RIGHT CTRL-F. But by default, your Ubuntu installation can not be displayed at full screen without the installation of VIRTUALBOX GUEST ADDITION. This software improves the performance of Guest OSes and introduces features like seamless mouse integration between Host and Guest PC and improved screen resolutions.

Unfortunately, the process of installing the Guest Addition is not very straight forward but, as usual, if you follow my lead, you can’t go wrong.
