President Obama is having a rough go of things lately. As noted here last week, for the first time in his presidency, more Americans disapprove of Obama (48%) than approve of him (45%), according to the latest WSJ/NBC poll. And 62% say the country is headed in the wrong direction.
“The American people are right,” says Howard Davidowitz of Davidowitz & Co. A critic of Obama’s, from the start, Davidowitz refers to him as the “worst” President of his lifetime, even worse than of Jimmy Carter, based on:
Davidowitz recognizes Obama was handed a difficult hand upon entering office, and admits the political system is dysfunctional. Actually, in the many times Davidowitz has appeared on Tech Ticker he's rarely had a nice thing to say about any politician, regardless of party.
What he'd like to see is a return to fiscal responsibility, lacking these days. "Ross Perot did a huge service to this country when he ran because all he talked about was the budget and what was going on and it forced Clinton to deal with it,” Davidowitz says.
ng changes.History comparison reports highlight the changes between two revisions of a page.Wikis are generally designed with the philosophy of making it easy to correct mistakes, rather than making it difficult to make them. Thus, while wikis are very open, they provide a means to verify the validity of recent additions to the body of pages. The most prominent, on almost every wiki, is the "Recent Changes" page—a specific list numbering recent edits, or a list of edits made within a given time frame.[14] Some wikis can filter the list to remove minor edits and edits made by automatic importing scripts ("bots").[15]
From the change log, other functions are accessible in most wikis: the revision history shows previous page versions and the diff feature highlights the changes between two revisions. Using the revision history, an editor can view and restore a previous version of the article. The diff feature can be used to decide whether or not this is necessary. A regular wiki user can view the diff of an edit listed on the "Recent Changes" page and, if it is an unacceptable edit, consult the history, restoring a previous revision; this process is more or less streamlined, depending on the wiki software used.[16]
In case unacceptable edits are missed on the "recent changes" page, some wiki engines provide additional content control. It can be monitored to ensure that a page, or a set of pages, keeps its quality. A person willing to maintain pages will be warned of modifications to the pages, allowing him or her to verify the validity of new editions quickly.[17] A watchlist is a common implementation of this.Some wikis also implement "patrolled revisions," in which editors with the requisite credentials can mark some edits as not vandalism. A "flagged revisions" system can prevent edits from going live until they have been reviewed.[18]
[edit] Searching
Most wikis offer at least a title search, and sometimes a full-text search. The scalability of the search depends on whether the wiki engine uses a database. Some wikis, such as PMWiki, use flat files.[19] MediaWiki's first versions used flat files, but it was rewritten by Lee Daniel Crocker in the early 2000 to be a database application. Indexed database access is necessary for high speed searches on large wikis. Alternatively, external search engines such as Google can sometimes be used on wikis with limited searching functions in order to obtain more precise results. However, a search engine's indexes can be very out of date (days, weeks or months) for many websites.
[edit] Software architecture
Wiki software is a type of collaborative software that runs a wiki system, allowing web pages to be created and edited using a common web browser. It is usually implemented as an application server that runs on one or more web servers. The content is stored in a file system, and changes to the content are stored in a relational database management system. Alternatively, personal wikis run as a standalone application on a single computer. For example: WikidPad.
[edit] Trustworthiness
Critics of publicly editable wiki systems argue that these systems could be easily tampered with, while proponents argue that the community of users can catch malicious content and correct it.[3] Lars Aronsson, a data systems specialist, summarizes the controversy as follows:
“ Most people, when they first learn about the wiki concept, assume that a Web site that can be edited by anybody would soon be rendered useless by destructive input. It sounds like offering free spray cans next to a grey concrete wall. The only likely outcome would be ugly graffiti and simple tagging, and many artistic efforts would not be long lived. Still, it seems to work very well.[7] ”High editorial standards in medicine have led to the idea of expert-moderated wikis.[20CControlling chanThe four basic types of users who participate in wikis are reader, author, wiki administrator and web.“ they firs
