What Heartbleed means

Heartbleed bug in the OpenSSL type of encryption technology used on many web servers is of grave concern – enough for Revenue Canada to close online submission of  income tax returns and accessing accounts until it can fix the security hole.  The bug has made it possible for usernames and passwords to be leaked.  It may be necessary for us all to change our passwords on all accounts.

An alarming lapse in Internet security has exposed millions of passwords, credit-card numbers and other sensitive bits of information to potential theft by computer hackers who may have been secretly exploiting the problem before its discovery.

The Heartbleed security bug has forced Canada’s tax agency to block public access to its online services just three weeks ahead of the April 30 deadline for filing personal income tax.

Slideshare for staying up to date

Slideshare is an excellent source of presentations for getting a quick overview. Acquired by LinkedIn in May 2012, it has content on business, travel, technology, career planning, and likely any topic you might search for.  Users upload  presentations, infographics, documents, videos, PDFs, and webinars. Viewers may easily follow favourite contributors and people in their LinkedIn network, and get updates on featured presentations.


For web searchers two to follow are:

Mary Ellen Bates – Super Searcher Tips from a session at Computers in Libraries. She mentions Millionshort.com as method for digging more deeply into Google’s index; also searching Twitter and some other social media searches; and some bits on Google Scholar

Karen Blakeman – How we really search: the end of Google’s supremacy – presentation at Southampton University, UK.  She covered social media, main web search engines, some specialty engines, images – much more.


Verifying information on the Net

Is what you just read in Twitter or in a blog true? How do you verify user-generated content? Dan Russell of Search Research  recommends Verification Handbook — one you should read

The Verification Handbook is a collection of short chapters about how-to-verify-social-media-information. It’s edited by Craig Silverman of the Poynter Institute (an organization you should know about) and the creator of the blog Regret the Error.

The book - Verification Handbook: Definitive guide to verifying digital content for emergency coverage – is free. Mathew Ingram, formerly of the Globe and Mail and a media expert, is one of the many authors.

Bing and Google drop search terms

Karen Blakeman asks Is Bing dropping search terms? (Mar 1), and it likely is. Gone are the days when we could count on search engines searching for ALL our terms. Too often our search terms are nowhere to be seen – even on large results sets.

Karen gives two ways to force Bing to include all terms. Interestingly, use the Boolean AND, or the prefix inbody:xxx

At Google we need to use Verbatim search, or intext:xxx. Don’t know about AND.

Google Syntax Tour

Melanie Pinola at LifeHacker offers students tips for searching Google. Hack Tricks – Google Search (Jan 25)

This is a fast tour of using syntax at Google–  such as site: to limit to a website; filetype: – to find a pdf or image file; intitle: to look for words in a title of a page. There are more.


  • Google discontinued ~ tilde for finding related words
  • Author or inauthor used to work for News and maybe Blogs – doesn’t now. Does work in Scholar but may not be reliable.

Article also has tips for Google Books and Scholar.

Of interest: Google Drive has a research tool – will grab the citation in the style you choose (MLA, APA, or Chicago).


Presentation on cost-effective searching

This presentation by Marcy Phelps at Internet  Librarian 2013 goes through the steps and approaches the information professional will want to employ to search quickly and effectively.

Cost-Effective Searching: Online strategies and practices to get the most for your search dollar and your time.

Has a couple of tips on using Google.  I wouldn’t use OR to the extent mentioned here. Google does more semantic interpretation of words and less keyword matching. Therefore, expanding a concept with OR may muddy results too much.

Greatest value is the reminder to use specialty sites – find them, collect them, know them, use them.

Marcy Phelps has other presentations at Slideshare – would be good to follow her for tools and techniques.
