  • Google Vs Microsoft
    GOOGLE VS MICROSOFT De strijd om de standaard in zoekmachineland Naam: Anne Helmond Studentnummer: 0449458 E-mail: [email protected] Instelling: Universiteit van Amsterdam Opleiding: Media en Cultuur, Nieuwe Media Datum: 12 juni 2006 Begeleider: Rens Bod KEYWORDS Search engines, market competition, standardization wars, Google, Microsoft, Netscape. SAMENVATTING Google is op dit moment de onbetwiste marktleider in zoekmachineland en deze positie lijkt onaantastbaar. De vraag is echter of dit wel zo is. Microsoft introduceerde onlangs zijn vernieuwde zoekmachine Live Search waarmee de aanval op de dominante positie van Google wordt ingezet. Deze strijd doet denken aan de browseroorlog uit de jaren negentig toen Microsoft met de introductie van Internet Explorer toenmalig marktleider Netscape binnen enkele jaren de markt uit drukte. De browseroorlog was een standaardisatie-oorlog die van Internet Explorer de standaard browser maakte. Dit paper zal argumenteren dat er wederom sprake is van een standaardisatie-oorlog, zowel opnieuw in de browsermarkt als in de zoekmachinemarkt. Tevens zal worden aangetoond dat de browser en de zoekmachine tegenwoordig zodanig geïntegreerd zijn dat de uitkomst van deze standaardisatie-oorlog grote gevolgen kan hebben voor de internetgebruiker. Door middel van een historische analyse van de eerste browseroorlog met betrekking tot de gebruikte concurrentietactieken zal getracht worden een beeld te schetsen van de mogelijke scenario's van de huidige oorlog in de zoekmachinemarkt. And so at last the beast fell and the unbelievers rejoiced. But all was not lost, for from the ash rose a great bird. The bird gazed down upon the unbelievers and cast fire and thunder upon them.

    International Journal of Management & Information Systems – Fourth Quarter 2011 Volume 15, Number 4 History Of Search Engines Tom Seymour, Minot State University, USA Dean Frantsvog, Minot State University, USA Satheesh Kumar, Minot State University, USA ABSTRACT As the number of sites on the Web increased in the mid-to-late 90s, search engines started appearing to help people find information quickly. Search engines developed business models to finance their services, such as pay per click programs offered by Open Text in 1996 and then Goto.com in 1998. Goto.com later changed its name to Overture in 2001, and was purchased by Yahoo! in 2003, and now offers paid search opportunities for advertisers through Yahoo! Search Marketing. Google also began to offer advertisements on search results pages in 2000 through the Google Ad Words program. By 2007, pay-per-click programs proved to be primary money-makers for search engines. In a market dominated by Google, in 2009 Yahoo! and Microsoft announced the intention to forge an alliance. The Yahoo! & Microsoft Search Alliance eventually received approval from regulators in the US and Europe in February 2010. Search engine optimization consultants expanded their offerings to help businesses learn about and use the advertising opportunities offered by search engines, and new agencies focusing primarily upon marketing and advertising through search engines emerged. The term "Search Engine Marketing" was proposed by Danny Sullivan in 2001 to cover the spectrum of activities involved in performing SEO, managing paid listings at the search engines, submitting sites to directories, and developing online marketing strategies for businesses, organizations, and individuals.

  • Top 5 Defacers Looking for Loop Holes Or Vulnerabilities to Exploit
    Cyber Intelligence Report, The original OSINT/APT CIR resource, since 2006. Social engineering (SE) has always been an extremely valuable and effective method for gathering information and exploiting vulnerabilities. From HUMINT to cyber warfare, SE is an invaluable asset to any attacker’s arsenal. This week’s episode covers the Social Engineering Toolkit (SET) http://youtu.be/cosWCrXSpt8 NSA META data used in drone strikes / DOJ Hacking: US centric. When those two stories hit the news, you have to think that what Edward Snowden did is completely justified. NSA claims that they only look at META data of your communications and the ex-Director just announced that they authorized kill commands using drone strikes against targets solely on META data. To quote the Church Lady (Dana Carvey), “Well isn’t that special…”. The Department of Justice now wants to use malware & exploitation as a legal means to track suspects. Well, if that is the case, shouldn’t these newly classified “cyber weapons” be protected under the 2nd Amendment for the right to bear arms and 1st Amendment of Freedom of Speech? With neither the current administration Image is an oldie but goodie from IOSS.gov or Eric Holder, the top Law Enforcement officer in the US willing to go on record as stating no Americans on American soil will be killed by a government owned drone (look up Rand Paul’s filibuster), this is a scary situation… “Chained exploits”: Just like hackers, lawyers and politicians are constantly Top 5 Defacers looking for loop holes or vulnerabilities to exploit.
