Inferno. 9P. 9P was revised for the 4th edition of Plan 9 under the name 9P2000 that contained various fundamental improvements. The latest version of the Inferno operating system also uses 9P2000. The Inferno file protocol was originally called Styx, but technically it has always been a variant of 9P. A server implementation of 9P for Unix, called u9fs, is included in the Plan 9 distribution. A kernel client driver for Linux is part of the v9fs project. 9P and its derivatives have also found application in embedded environments, such as the Styx on a Brick project.
Server applications[edit] Many of Plan 9's applications take the form of 9P servers. Implementation[edit] 9P sends the following messages between clients and servers.[1] These messages correspond to the entry points in the Plan 9 vfs layer that any 9P server must implement. version Negotiate protocol version error Return an error flush Abort a message auth, attach Messages to establish a connection walk Descend a directory hierarchy create, open clunk. Plan 9 from Bell Labs. Plan 9 from Bell Labs is a distributed operating system, originally developed by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. It takes some of the principles of Unix, developed in the same research group, but extends these to a networked environment with graphical terminals. The name Plan 9 from Bell Labs is a reference to the Ed Wood 1959 cult science fiction Z-movie Plan 9 from Outer Space.[5] Also, Glenda, the Plan 9 Bunny, is presumably a reference to Wood's film Glen or Glenda.
The system continues to be used and developed by operating system researchers and hobbyists.[6][7] History[edit] Plan 9 replaced Unix as Bell Labs's primary platform for operating systems research. A user and development community, including current and former Bell Labs personnel, produced minor daily releases in form of ISO images. Design concepts[edit] —Sape J. Its designers state that: 9P protocol[edit] Union directories and namespaces[edit] /proc[edit] /net[edit]
Web 2.0. World Wide Web sites that use technology beyond the static pages of earlier Web sites Web 2.0 (also known as participative (or participatory)[1] web and social web)[2] refers to websites that emphasize user-generated content, ease of use, participatory culture and interoperability (i.e., compatibility with other products, systems, and devices) for end users.
The term was coined by Darcy DiNucci in 1999[3] and later popularized by Tim O'Reilly and Dale Dougherty at the first Web 2.0 Conference in 2004.[4][5][6] Although the term mimics the numbering of software versions, it does not denote a formal change in the nature of the World Wide Web,[7] but merely describes a general change that occurred during this period as interactive websites proliferated and came to overshadow the older, more static websites of the original Web.[8] History[edit] Web 1.0[edit] Some Web 2.0 capabilities were present in the days of Web 1.0, but were implemented differently.
Characteristics[edit] Web 2.0[edit] Search. Collaborate and Connect with Subversion. Consider this: You own a small web design and development shop. Maybe it’s just you and a couple of other people. Because of your size, you rely heavily on outside subcontractors. Subcontractors allow you to take on more projects, make more money, and scale your business carefully. Managing even a few contracted workers is challenging. At some point, you will hit a rough patch where subcontractors don’t deliver on time, don’t meet your quality standards, or—at worst—disappear and never complete the job.
Subversion connects and promotes collaboration#section1 Subversion (SVN) is a version control system that allows you to track and store code changes, collaborate, and share project files. Visibility is a good thing#section2 Subversion also keeps everyone on your team involved in the project: commits and project changes become visible as they are made (see The Tools You Need, below). Make it mandatory#section3 Are there exceptions to this rule? Set expectations#section5. Get Started with Git. If you’re a designer or developer, you’ve probably heard about Git, and you might know that it has become immensely popular, especially among the open source community.
Though it may seem cryptic at first, this version control system could change the way you work with text, whether you’re writing code, or a novel. Article Continues Below This article covers why version control is important, how to install the Git version control system, and how to get started with your first repository. Once you start using Git, you’ll want to throw everything into it, from full-blown apps to blog post drafts, because it’s so easy and versatile.
Why do I need version control? While it may be obvious that large development teams should have sophisticated code-management systems to track releases and bugs, and to avoid stepping on each others’ toes, it might not be immediately clear why individuals would need version control—especially designers or writers. With Git, though, you can do much more. Installing a Private Git Repository on your Shared Hosting Account, BlueHost | I On Rails. The reason I added this blog entry is because I tried to set up a private Git repository on BlueHost (shared hosting account) and didn’t find all of the information I needed in one place. I called BlueHost and they told me they allow it but won’t support it. Initially, I wasn’t sure if it was possible to do it. However, one person at BlueHost indicated to me that it’s possible to do set this up on BlueHost so I continued my efforts and became successful in setting this up. I’m a RoR developer and also starting iPhone development with a friend.
We were investigating different SCM to use and how we can set up a remote Git repository we both could connect to, but also didn’t want to spend any more money than we already are. BlueHost allows you to host unlimited domains, allows you to host RoR sites, provides an ssh account so it provides everything we need, at least while still very small. Install Git on your BlueHost shared hosting account (build from source code): Apache Subversion. Distellamap. Click any of the images above for more detail Like any other game console, Atari 2600 cartridges contained executable code also commingled with data. This lists the code as columns of assembly language. Most of it is math or conditional statements (if x is true, go to y), so each time there's "go to" a curve is drawn from that point to its destination. When a byte of data (as opposed to code) is found in the cartridge, it is shown as an orange row: a solid block for a "1" or a dot for a "0".
The row is eight elements long, representing a whole byte. The original version of these images are a series of 13 x 19 inch prints where you can actually read the individual bits of text. In response to requests, you can now purchase prints of these images. How to Create an Organic Web Design (and Showcase) Organic design is commonly applied to products such as chairs, electronic equipment, books and home décor. Following the same principles, organic web design has recently emerged as a trend. Professional designers and companies have taken a more natural approach to creating their websites, logos and packaging, leaving behind the overtly technological sheen of the early 2000s.
Yes, fellow designers, it is safe to say that the new age of organic design for websites and corporate logos has taken effect. Whether overt or subtle, whether scanned elements or graphics that mimic nature, organic web design has taken on many forms. What Makes an Organic Web Design? Though the name suggests that some kind of ecological statement is being made, organic web design is more about bringing natural elements into a technological environment. Using materials, textures and fabrics that hint at organic elements Objects such as muslin, burlap, papyrus, paper, tape and wood.

If you’re a front end developer or a designer who likes to code, CSS-based layouts are at the very core of your work. In what might be a refresher for some, or even an “a-ha!” For others, let’s look at the CSS position property to see how we can use it to create standards-compliant, table-free CSS layouts. Article Continues Below CSS positioning is often misunderstood. Sometimes, in a bug-fixing fury, we apply different position values to a given selector until we get one that works.
This is a tedious process that can work for a time, but it behooves us to know why specifying something like position: relative can fix your layout bug. My hope is that we can learn the position property’s values and behaviors, and most importantly, how a value can affect your markup. The CSS specification offers us five position properties: static, relative, absolute, fixed, and inherit. Get with the flow#section1 First, let’s take a step back to recognize the world we’re working in.
