Portage Lake is a glacial lake in the Chugach National Forest of Alaska.
 It sits in a long, heavily glaciated valley, and abuts the calving face of Portage Glacier at its southern end.
 The lake has only become visible since approximately 1914, with the rapid retreat of Portage Glacier.
Insex was one of the biggest BDSM pornographic websites on the Internet and arguably the most extreme American pornographic production featuring female submissives.
 It was also a leading innovator in both live video streaming, pioneering the concept before broadband Internet access existed, and in the depiction of BDSM practices on the Internet.
 It existed from 1997 to 2005 and was run by "Intersec Interactive Inc.", a company owned by the website's creator, Brent Scott, former Carnegie Mellon professor, known as "pd".
 Insex developed a cult following among BDSM enthusiasts due to its uncommonly severe and realistic depiction of sadomasochistic practices.
 It was also known for its interactive "Live Feeds" which allowed members to make direct suggestions and requests.
 In late 2006, Insex ended the production of original material, citing increased pressure from conservatives within the U.S. Justice Department.

The rainbow flag, commonly known as the gay pride flag or LGBT pride flag, is a symbol of lesbian, gay, bisexual and transgender (LGBT) pride and LGBT social movements.
 Other uses of rainbow flags include a symbol of peace and the colors reflect the diversity of the LGBT community, as the flag is often used as a symbol of gay pride during LGBT rights marches.
 While it originated in Northern California, the flag is now used worldwide.
The pansexual pride flag was designed as a symbol for the pansexual community to use.
 The pansexual pride flag has been found on various internet sites since mid-2010.
 It is similar to the LGBT flag, which is used as a symbol for the lesbian, gay, bisexual, and transgender community.
 The pansexual pride flag is used to increase visibility and recognition for the pansexual community, and to distinguish it from bisexuality.
 It is used to indicate that pansexuals have romantic attractions and relationships with people of different genders and sexualities.
 The theory of pansexuality aims to challenge existing prejudices, which can cause judgment, ostracism, and serious disorders within society.
Several motivations underlie the project.
 The primary ambition of MOM is to preserve an image of our era, created by numerous participants all over the planet.
 MOM will also contain information which our society is obliged to forward to the future: e.g. description of nuclear waste repositories.
 MOM collaborates with the NEA and SKB.
 Although the most obvious ambition and often described in the media is the concern about preserving our knowledge, this is not the primary goal of MOM.
 Serving as a time capsule MOM is both: in a time frame of millennia it is the story about us, and in a time frame of decades it is a backup.
 In times where global warming, nuclear danger and biological warfare threaten the existence of civilization, saving the core knowledge and culture acquired over centuries is a backup measure.
 In case of a collapse, the MOM project could help survivors to rebuild civilization.
 Linked to this, an another reason is of political order: facing the lack of reactivity of authorities concerning global warming, the MOM project is a reminder of what can happen.
 Roman and Greek civilizations whose histories have been reconstructed by the small percentage of texts and artifacts which survived until our days are examples that have inspired the MOM project.
 Finally, it's a critic of our digital civilization : according to Kunze, maybe nothing of the 21st century will last in the future, since most of our interactions are now virtual.
 The "accuracy versus bullshit" is one of the main themes of the MOM project, worried about loss of information, the project can only aim to save a fragment of the information produced until today, but this fragment has to be representative.
Russian Internet restriction bill (Federal law of Russian Federation no. 139-FZ of 2012-07-28) is a law passed by the Russian State Duma in 2012 which replaced procedure of shutting down telecom operators by prosecutors' orders with a blacklist of Internet sites containing alleged child pornography, drug-related material, extremist material, and other content illegal in Russia.
 This blacklist was supposed to be implemented and supervised by a self-regulating NGO of Internet users, but it was never created and this duty was assumed by government agency Roskomnadzor.
 The bill also introduced several other changes in the law, including liability for providers of telecom services for failing to protect children.
 Some critics expressed concern that the bill could be used to censor the Internet.
 Others noted that it would be expensive and, as written, contained many technical problems that would negatively impact legitimate Internet use.
The rubber pride flag, also known as the latex pride flag is a symbol used by members of the rubber and latex fetish community.
 It was designed in 1994 by Peter Tolos and Scott Moats.
 The rubber pride flag is similar to the leather pride flag, as a symbol representing the community.
Pansexuality, or omnisexuality, is the sexual, romantic or emotional attraction towards people regardless of their sex or gender identity.
 Pansexual people may refer to themselves as gender-blind, asserting that gender and sex are not determining factors in their romantic or sexual attraction to others.
The gay pride flag of South Africa is a gay pride symbol that aims to reflect the freedom and diversity of the South African nation and build pride in being an LGBT South African.
