CSS Font Stacks by Classification
CSS font stacks by classification Written by Frode Helland When Johann Gutenberg printed his famous Bible more than 600 years ago, the only typeface available was his own. Since the invention of moveable lead type, throughout most of the 20th century graphic designers and printers have been limited to one – or perhaps only a handful of typefaces – due to costs and availability. Since the birth of desktop publishing and the introduction of the worlds firstWYSIWYG layout program, MacPublisher (1985), the number of typefaces available – literary at our fingertips – has grown exponen- tially. Still, well into the 21st century, web designers find them selves limited to only a handful. Web browsers depend on the users own font files to display text, and since most people don’t have any reason to purchase a typeface, we’re stuck with a selected few. This issue force web designers to rethink their approach: letting go of control, letting the end user resize, restyle, and as the dynamic web evolves, rewrite and perhaps also one day rearrange text and data. As a graphic designer usually working with static printed items, CSS font stacks is very unfamiliar: A list of typefaces were one take over were the previous failed, in- stead of that single specified Stempel Garamond 9/12 pt. that reads so well on matte stock. Am I fighting the evolution? I don’t think so. Some design principles are universal, independent of me- dium. I believe good typography is one of them. The technology that will let us use typefaces online the same way we use them in print is on it’s way, although moving at slow speed. -
The Unicode Cookbook for Linguists: Managing Writing Systems Using Orthography Profiles

We introduce the basic concepts needed to understand how writing systems and character encodings function, and how they work together. The intersection of the Unicode Standard and the International Phonetic Al- phabet is often not met without frustration by users. Nevertheless, thetwo standards have provided language researchers with a consistent computational architecture needed to process, publish and analyze data from many different languages. We bring to light common, but not always transparent, pitfalls that researchers face when working with Unicode and IPA. Our research uses quantitative methods to compare languages and uncover and clarify their phylogenetic relations. However, the majority of lexical data available from the world’s languages is in author- or document-specific orthogra- phies. -
A Study of Cryptographic File Systems in Userspace

Thus, the security of the stored data is extremely important. Conventionally, there are two methods of storage of the data, the first being hiding the data and the second being encryption of the data. However, finding out hidden data is simple, and thus, is very unreliable. The second method, which is encryption, allows for accessing the data by only the person who encrypted the data using his passkey, thus allowing for higher security. Typically, a file system is implemented in the kernel of the operating systems. However, with an increase in the complexity of the traditional file systems like ext3 and ext4, the ones that are based in the userspace of the OS are now allowing for additional features on top of them, such as encryption-decryption and compression. -

Can Libreoffice and Apache Openoffice Be Alternatives to MS-Office from Consumer's Perspective?
2016 2 nd International Conference on Social, Education and Management Engineering (SEME 2016) ISBN: 978-1-60595-336-6 "Make It Possible" Study: Can LibreOffice and Apache OpenOffice Be Alternatives to MS-Office from Consumer's Perspective? Jun IIO 1,* and Shusaku OHGAMA 2 1Socio-informatics Dept. Faculty of Letters, Chuo University, 742-1 Higashinakano, Hachioji-shi, Tokyo, Japan 2Information Technology Dept. Information Systems Div., Sumitomo Electric Industries, Ltd., 4-5-33 Kitahama, Chuo-ku, Osaka-shi, Osaka, Japan *Corresponding author Keywords: Open-source software, LibreOffice, OpenOffice, Productivity suites. Abstract. There are many guidebooks which offer some instruction of using productivity suites, and most of them focus on Microsoft's Office (MS-Office,) because it is the dominant products in the market. However, we have some other productivity suites, such as LibreOffice and Apache OpenOffice, as the alternative of MS-Office. Therefore, we investigated whether such software could be used properly, within the content of the guidebooks which are widely used. In this paper, the results of our investigation show that the interoperability of such software has already reached a tolerable level from a practical perspective. Introduction Recently, we can find in bookstores many books for reference that provide guidelines on how to operate productivity suites. However, most of them only focus on Microsoft's Office suites (MS-Office,) because it has the largest market share in the world in the productivity software market. On the other hand, there are some other options, such as LibreOffice and Apache OpenOffice. In recent days, persons in businesses face some problems in using these productivity suites. -

Wozu dient Typografie? 4 Robert Bringhurst fasst es folgendermaßen zusammen: »[...] typography should perform these services for the reader: I invite the reader into the text; I reveal the tenor and the meaning of the text; I clarify the structure and the order of the text; I link the text with other existing elements; I induce a state of energetic repose, which is the ideal condition for reading.« Was ist digitale Typografie? 5 • »Digital typography is the technology of using computers for the design, preparation, and presentation of documents, in which the graphical elements are organized, positioned, and themselves created under digital control.« (Richard Rubinstein) • »[...] the problem of printing beautiful books had changed from a problem of metallurgy to a problem of optics and then to a problem of computer science. [...] The future of typography depends on the people who know the most about creating patterns of 0s and 1s; it depends on mathematicians and computer scientists.« (Donald E. -

A Novel Cryptographic Framework for Cloud File Systems and Cryfs, a Provably-Secure Construction
A Novel Cryptographic Framework for Cloud File Systems and CryFS, a Provably-Secure Construction Sebastian Messmer1, Jochen Rill2, Dirk Achenbach2, and J¨ornM¨uller-Quade3 1 [email protected] 2 FZI Forschungszentrum Informatik frill,[email protected] 3 Karlsruhe Institute of Technology (KIT) [email protected] Abstract. Using the cloud to store data offers many advantages for businesses and individuals alike. The cloud storage provider, however, has to be trusted not to inspect or even modify the data they are entrusted with. Encrypting the data offers a remedy, but current solutions have various drawbacks. Providers which offer encrypted storage themselves cannot necessarily be trusted, since they have no open implementation. Existing encrypted file systems are not designed for usage in the cloud and do not hide metadata like file sizes or directory structure, do not provide integrity, or are prohibitively inefficient. Most have no formal proof of security. Our contribution is twofold. We first introduce a comprehensive formal model for the security and integrity of cloud file systems. Second, we present CryFS, a novel encrypted file system specifically designed for usage in the cloud. Our file system protects confidentiality and integrity (including metadata), even in presence of an actively malicious cloud provider. We give a proof of security for these properties. Our implemen- tation is easy and transparent to use and offers performance comparable to other state-of-the-art file systems. 1 Introduction In recent years, cloud computing has transformed from a trend to a serious competition for traditional on-premise solutions. Elastic cost models and the availability of virtually infinite resources present an alternative to offers of a preset volume.
