The ant is not a very common symbol in heraldry, but when depicted the ant is usually accompanied by a drawing of an anthill. The symbol of the ant traditionally signified one who was a strong labourer, wise and provident in all his affairs. On English arms, an annulet was a mark of cadency signifying the fifth son. In some circles an annulet represented riches. The annulet may have been borne to indicate that the bearer had the superior qualities of a knight. The Romans are said to have worn a ring as a sign of knighthood and rings are still used at some coronations and in the institution of knighthood. As a closed circle, it is symbolic of continuity and wholeness. Maritime devices are found less often on the continent where many countries are essentially landlocked, but Cosmo de Medici, the Duke of Etruria is an example of a Spanish noble who bore two anchors on his shield. It was even a device that was once born by King Richard I. It is a common figure in the English armour, which is not surprising given that Britain is an island. It is also an appropriate device for the coat of arms of a family with a seafaring tradition. The anchor is the emblem of salvation and hope. It is extremely uncommon in heraldry.Īn amphiptere is a winged serpent found very rarely in heraldry, though it does exist as a supporter and as a charge on a shield occasionally.Īn amphisboena is a winged serpent with two legs and a head at both ends of its body however the drawing of this creature does not strictly follow this description.

The peroxide concentration of a strip’s whitener really only tells half of the story. The strips themselves are clear, thin, flexible pieces of plastic (polyethylene) that have been uniformly coated on one side with a thin film that contains hydrogen peroxide (of varying concentration depending on the product, see list below).Ĭomparison of the hydrogen peroxide concentration of Whitestrips®. ▲ Section references – Gerlach What are whitening strips made out of? ![]() As compared to all other (reasonably effective) at-home methods, this is probably the simplest, least-messy way to whiten your teeth.And aids with product safety and reduces your potential for side effects by way of minimizing the quantity of whitener that’s used during each treatment. This helps to ensure predictable whitening results. Since the whitener is applied by the manufacturer (and not the end-user), the dosing you receive is very controlled and consistent.This helps to increase effectiveness and decrease the user’s potential for side effects. Because only one side of the strip is coated with the bleaching agent, it acts as a barrier that helps to both prevent the dilution of the whitener and minimize its contact with opposing soft tissues.And that means it won’t cause mechanical irritation to soft tissues like bleaching trays can. The flexible nature of a strip readily conforms to the shape and alignment of your teeth.(Compared to the convenience, ease, and simplicity of using whitening strips, the process of performing tray bleaching treatments is generally considered to be a messier, more inconvenient, and more noticeable when worn process.) b) Advantages of a “strip” design. The primary selling point of this method is that it provides a way for a person to perform comparatively effective whitening treatments, at home and on their own, without having to use bleaching trays. a) Main advantage of using whitening strips.

![]() It was the first WYSIWYG computer, and due in large part to PageMaker and Apple's LaserWriter printer, it ignited the desktop publishing revolution, turning the Macintosh from an early let-down into a notable success. italics, bold, shadow, outline) unlike other personal computers of the time. The Macintosh is credited with popularizing the graphical user interface, and owing to Jobs' interest in typography, it came with an unprecedented variety of fonts and type styles (e.g. Apple soon improved the Mac's performance by releasing a 512K revision and an external floppy disk drive. The first Macintosh nevertheless generated cult enthusiasm among buyers and some developers, who rushed to develop entirely new programs for the platform, including PageMaker, MORE, and Excel. Most members of the original Macintosh team left Apple, including Jobs, who left to found NeXT after being forced out by CEO John Sculley. Sales initially met projections, but then sputtered due to the machine's low performance, single floppy disk drive (requiring users to frequently swap disks), and initial lack of applications. Upon its 1984 release, the first Macintosh was described as a "revolution" by the New York Times. The initial team consisted of Raskin, hardware engineer Burrell Smith, and Apple co-founder Steve Wozniak Steve Jobs joined in 1981 after being removed from the Lisa team, and was able to gradually take control of the project due to Wozniak's temporary absence from the company following an airplane crash earlier that year. Raskin named the computer after his favorite type of apple, the McIntosh. Conceived in 1979 by Jef Raskin, the Macintosh was envisioned as an affordable, easy-to-use computer for the masses, with the Lisa's graphical interface. Parallel to the Lisa's development, a skunkworks team at Apple was working on another project. This was to no avail: hampered by its high $9,995 price and lack of available software, the Lisa was commercially unsuccessful. Though the Lisa's graphical user interface was partially inspired by the work of Xerox PARC, it also went far beyond PARC's prototypes, and introduced original innovations: the ability to drag-and-drop files, menu bars, and double-clicking. After IBM introduced the IBM PC in 1981, its sales quickly surpassed the Apple II in response, Apple introduced the Apple Lisa in 1983. In the late 1970s, the Apple II was one of the most popular computers on the American market, especially in education. Steve Jobs with the original Macintosh, January 1984 After Tim Cook replaced Jobs as CEO, the Mac underwent a period of neglect, but was later reinvigorated with the introduction of popular high-end Macs and the Apple silicon transition, which brought the Mac to the same ARM architecture as iOS devices. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the 2005-06 Intel transition, and brought features from the iPhone back to the Mac. After a period of initial success, the Mac languished in the 1990s until the 1996 acquisition of NeXT brought Steve Jobs back to Apple. The first Mac was released in 1984, and was advertised with the highly acclaimed "1984" ad. Macs are sold with the macOS operating system. The product lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. ![]() The Mac, short for Macintosh (its official name until 1999), is a family of personal computers designed and marketed by Apple Inc.

So what can Arti do? Right now, Arti can successfully bootstrap, run as a SOCKS proxy, and connect over the Tor network. It doesn't support Tor's anti-censorship features yet, and it can't connect to onion services yet.įinally, note that today's Arti is missing several key security features for privacy: you shouldn't use it for browsing if you have actual privacy needs at all. But with our Arti rewrite, we can take embedding into account from the start, to help support applications down the road.) What can Arti do today? What features are missing?įirst off: Don't use Arti for real privacy yet.Īrti doesn't yet run as a relay at all. For example, the complicated structure of the C code has made it hard to adopt for embedding into other applications. (And while we're writing a new implementation, we can clean up design issues that have been hard to fix in C. With a rewrite, we figured that we can keep our existing C code stable and make only minimal changes to it, while building up a working base of Rust code to serve as a basis for future development. And untangling the code is risky, for all the same reasons that working in C is typically risky. ![]() That makes it hard for us to rewrite our code one module at a time, without first untangling it to be more modular. Our problem here is that the modules in our existing C code are not terribly well separated from one another: most modules are reachable from most other modules. Why a full rewrite?Īt one point, we had hoped to slowly replace Tor's C code with Rust, one piece at a time. Because of that, Arti's circuit cryptography has been multicore from day 1, at very little additional programming effort. If one thread accesses a piece of state at the same time that another thread is changing it, then your whole program can exhibit some truly confusing and bizarre bugs.īut in Rust, this kind of bug is easy to avoid: the same type system that keeps us from writing memory unsafety prevents us from writing dangerous concurrent access patterns. C's support for thread-safety is quite fragile, and it is very easy to write a program that looks safe to run across multiple threads, but which introduces subtle bugs or security holes. Here's a case where Rust's safety can really help us.įor years now, we've wanted to split Tor's relay cryptography across multiple CPU cores, but we've run into trouble. Since 2016, we've been tracking all the security bugs that we've found in Tor, and it turns out that at least half of them were specifically due to mistakes that should be impossible in safe Rust code. That's a huge win for us in programming and debugging time, and a huge win for users in security and reliability. To a first approximation, if the code compiles, and it isn't explicitly marked as " unsafe", then large categories of bugs are supposed to be impossible. What's more, it's got some really innovative features that let the language enforce certain safety properties at compile-time. It's a high-level language, and significantly more expressive than C. Rust seems like the clearest way out of our bind. ![]() This slows us down seriously, and increases the cost of adding new features. Everything we write takes more code than we'd like it to, and we need to double-check even the safest-looking code to make sure it doesn't fall prey to any of C's list of enormous gotchas. Although C is venerable and ubiquitous, it's notoriously error-prone to use, and its lack of high-level features make many programming tasks more complex than they'd be in a more modern language.įor us, these problems mean that programming in C is a slow and painstaking process. Today's Tor is written in the C programming language. Since then, Tor has grown to handle millions of users around the world. In 2006, we incorporated the Tor Project as a nonprofit charity. We started Tor back around 2002, based on earlier Onion Routing designs from the mid-1990s. Tor is also a program (in C) that provides client-side and server-side implementations of those protocols. Tor is a set of protocols to provide anonymity, privacy, and censorship resistance on the Internet. Thanks to funding from Zcash Open Major Grants (ZOMG), we can finally put the Arti project up in our priorities list, and devote more time to it.īelow I'll talk about why we're doing this project, what it means for Tor users and operators, where it's going in the future, and how people can help. ![]() Over the past year or so, we've been working on "Arti", a project to rewrite Tor in Rust. ![]() Today I'm happy to announce a new era in Tor implementation. ![]() |
