Land or "ground" shipping can be either by train or by truck. Trucking is easily the most popular form of shipping. Even in Air and Sea shipments, ground transportation is still required to take the product from its origin to the airport or seaport and then to its destination. Ground transportation is typically more affordable than air shipments, but more expensive than shipping by sea. Trucks are also much faster than ships and rail but slower than planes. Many trucks will take freight directly from the shipper to its destination in what is known as a door to door shipment. Vans and trucks of all sizes make deliveries to sea ports and air ports where freight is moved in bulk also. Much shipping is done aboard actual ships. An individual nation's fleet and the people that crew it are referred to its "merchant navy" or "merchant marine". Merchant shipping is essential to the world economy, carrying the bulk of international trade. The ships are also extremely expensive constructions themselves, being some of the largest man-made vehicles ever. The term originates with the shipping trade of wind power ships, and has come to refer to the delivery of cargo and parcels of any size above the common mail of letters and postcards. Ground shipping can be cheaper and less restrictive to size, quantity, weight, and type of freight than by air transport. Air transport is usually reserved for products which must be sent within a shorter time frame. Some carriers offer ground shipping that operates on an exact timeline as air does. This is a recent development becoming mainstream among major carriers since the late 1990s. UPS and FedEx both offer guaranteed day ground shipping. Freight on Board OR Free On Board (FOB): freight on board means that the exporter delivers the goods at the specified location. Example, FOB Kunming Airport (the exporter delivers the goods at Kunming airport). This means exporter is bound to deliver the goods at the Kunming Airport at his cost and expenses. In the case, the freight and other expenses for outbound trafic is borne by the importer.
Free software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with restrictions only to ensure that further recipients can also do these things. To make these acts possible, the human readable form of the program (called the source code) must be made available. The source code may be either accompanied by a software license saying that the copyright holder permits these acts (a free software licence), or be released into public domain, so that these rights automatically hold. Since free software may be freely redistributed, it generally is available at little or no cost. Free software business models are usually based on adding value such as support, training, customization, integration, or certification. At the same time, some business models which work with proprietary software are not compatible with free software, such as those that depend on a user having no choice but to pay for a licence in order to lawfully use a software product. In the 50s, 60s, and 70s, it was normal for computer users to have the freedoms provided by free software. Software was commonly shared by individuals who used computers and by hardware manufacturers who were glad that people were making software that made their hardware useful. In the 70s and early 80s, the software industry began to apply copyright law, and began using technical measures such as only distributing binary copies, to prevent computer users from being able to study and modify the software.[2] In 1983, Richard Stallman launched the GNU project after becoming frustrated with the effects of the change in culture of the computer industry and users. Software development for the GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. He introduced a free software definition and "copyleft", designed to ensure software freedom for all. Free software is a huge international effort, producing software used by individuals, large organizations, and governmental administrations. Free software has a very high market penetration in server-side Internet applications such as the Apache web server, MySQL database, and PHP scripting language. Completely free computing environments are available as large packages of basic system software such as the many Linux distributions and FreeBSD. Free software developers have also created free versions of almost all commonly used desktop applications such as web browsers, office productivity suites, and multimedia players. It is important to note, however, that in many categories, free software for individual workstation or home users has only a fraction of the market share of their proprietary competitors. Most free software is distributed online without charge, or off-line at the marginal cost of distribution, but this is not required, and people may sell copies for any price. The economic viability of free software has been recognised by large corporations such as IBM, Red Hat, and Sun Microsystems. Many companies whose core business is not in the IT sector choose free software for their Internet information and sales sites, due to the lower initial capital investment and ability to freely customize the application packages. Also, some non-software industries are beginning to use techniques similar to those used in free software development for their research and development: scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under copyleft licenses (see the OpenCores project, for instance). Creative Commons and the free culture movement have also been largely influenced by the free software movement. The first formal definition of free software was published by FSF in February 1986.[4] That definition, written by Richard Stallman, is still maintained today and states that software is free software if people who receive a copy of the software have the following four freedoms: Thus, free software means that computer users have the freedom to cooperate with whom they choose, and to control the software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, Richard Stallman has long said: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech', not as in 'free beer'".[5] The BSD-based operating systems, such as FreeBSD, OpenBSD, and NetBSD, do not have their own formal definitions of free software but users of these systems generally find the same set of software to be acceptable. However, rather than advocate the use of copyleft free software licenses, they see copyleft as being merely tolerable. Instead, they advocate permissive free software licenses which allow others to make software based on their source code and then not, in turn, also distribute the source. Their view is that this permissive approach is more free. The Kerberos, X.org, and Apache software licenses are substantially similar in intent and implementation. All of these software packages originated in academic institutions interested in the widest possible technology transfer (University of California, MIT, and UIUC). All free software licenses must grant people all the freedoms discussed above. However, unless the applications' licenses are compatible, combining programs by mixing source code or directly linking binaries is problematic, because of license technicalities. Programs indirectly connected together may avoid this problem. Apart from these two organizations, the Debian project is seen by some to provide useful advice on whether particular licenses comply with their Debian Free Software Guidelines. Debian doesn't publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That is summarized at the Debian web site.[7] However, it is rare that a license is announced as being in-compliance by FSF or OSI and not the other (the Netscape Public License used for early versions of Mozilla being an exception), so exact definitions of the terms have not become hot issues. BSD-style licenses, so called because they are applied to much of the software distributed with the BSD operating systems. The author retains copyright protection solely to disclaim warranty and require proper attribution of modified works, but permits redistribution and modification in any work, even proprietary ones, again, for as long as the author wishes. There is debate over the security of free software in comparison to proprietary software, with a major issue being security through obscurity. A popular quantitative test in computer security is using relative counting of known unpatched security flaws. Generally, users of this method advise avoiding products which lack fixes for known security flaws, at least until a fix is available. Some claim that method counts more vulnerabilities for the free software, since their source code is accessible and their community is more forthcoming about what problems exist.[8] Free software advocates rebut that proprietary software do not have published flaws, but flaws could exist and are possibly already known to malicious users. The ability to view and modify the software provides many more people who can analyse the code, and possibly have a higher rate of finding bugs and flaws than an average corporation. Having access to the source code also makes creating spyware far more difficult.[9] Under the free software business model, free software vendors may charge a fee for distribution and offer pay support and software customization services. Proprietary software uses a different business model, where a customer of the proprietary software pays a fee for a license to use the software. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for a fee. Free software is generally available at little to no cost and can result in permanently lower costs compared to proprietary software. With free software, businesses can fit software to their specific needs by changing the software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage. Such an agreement is made separately from the free software license. In 2006, OpenBSD started the first campaign against the use of binary blobs, in kernels. Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts the users' freedom to effectively modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs, they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free. Larry McVoy invited high-profile free software projects to use his proprietary versioning system, BitKeeper, free of charge, in order to attract paying users. In 2002, Linux coordinator Linus Torvalds decided to use BitKeeper to develop the Linux kernel, a free software project, claiming no free software alternative met his needs. This controversial decision drew criticism from several sources, including the Free Software Foundation's founder Richard Stallman.[14] ^ Why “Open Source” misses the point of Free Software.�“The philosophy of open source, with its purely practical values, impedes understanding of the deeper ideas of free software; it brings many people into our community, but does not teach them to defend it.”
Fioricet and Esgic are brand name drugs made from a combination of acetaminophen (325 mg), butalbital (a barbiturate, 50 mg), and caffeine (40 mg). They are indicated for the treatment of tension headaches and muscle contraction headaches. Although not indicated, they are commonly used to treat migraines and other pain related ailments. Note that Fioricet (and some other pain medications) are implicated as causing repeat headaches with over-use (see NYT citation below) Fioricet is indicated for the treatment of complex and muscle contraction headaches. It is also commonly prescribed for migraines although it is not FDA indicated for this use. The usual adult dose is 1-2 tablets every four hours as needed, not exceeding six tablets in a 24 hour period.FSAFASF Butalbital has generalized depressant effect on central nervous system and, in very high doses, has peripheral effects. Acetaminophen has analgesic and antipyretic effects; its analgesic effects may be mediated through inhibition of prostaglandin synthetase enzyme complex. Caffeine is thought to produce constriction of cerebral blood vessels.
