EDge21 Home | Heurist Network UNIX History Below, you can see the preview of the Unix History (move on the white zone to get a bigger image): This is a simplified diagram of unix history. There are numerous derivative systems not listed in this chart, maybe 10 times more! In the recent past, many electronic companies had their own unix releases. This diagram is only the tip of an iceberg, with a penguin on it ;-). If you want to print this timeline, you can freely download one of the following PDF files: Warning: it seems that Adobe Reader has some problems reading the large plotter version of the Unix History chart, but happily you can use another PDF viewer for this task. Here is the ChangeLog of this history. Note 1 : an arrow indicates an inheritance like a compatibility, it is not only a matter of source code. Note 2 : this diagram shows complete systems and [micro]kernels like Mach, Linux, the Hurd... Note 3 : I have now a page where I explain how I build this chart.

Nomenklatura - Data Matching and Reconciliation Made Easy - Open Knowledge Labs Nomenklatura is a simple service that makes it easy to maintain a canonical list of entities such as persons, companies or event streets and to match messy input, such as their names against that canonical list – for example, matching Acme Widgets, Acme Widgets Inc and Acme Widgets Incorporated to the canonical “Acme Widgets”. With Nomenklatura its a matters of minutes to set up your own set of master data to match against and it provides a simple user interface and API which you can then use do matching (the API is compatible with Open Refine’s reconciliation function). Nomenklatura can not only store the master set of entities you want to match against but also will learn and record the various aliases for a given entity - such as a person, organisation or place - may have in various datasets. As such Nomenklatura chooses a design half way between an entity database (such as OpenCorporates, PopIt or similar services) and a automated de-duplication software (such as dedupe or SILK).

Quickstart Guide | DSpace How do you know if DSpace is the right choice for you? How do you get started in your evaluation process? Follow the steps below to explore DSpace in more detail. Step 1 - Watch a DSpace overview Watch the DSpace introductory video. For a more in-depth preview, you can watch the one hour All About DSpace Webinar recording. Step 2 - Try DSpace for yourself Play with a demo version of DSpace and see how it works before you download and install the entire platform. Alternatively, you may work through the The DSpace Course with the DSpace Live CD, created by JISC's Repositories Support Project (RSP). Step 3 - Learn about how to set up a repository Review the Digital Repositories infoKit created by JISC/RSP, it is a practical 'how to' guide to setting up and running digital repositories. Alternatively you can review the LEADIRS Workbook: Creating an Institutional Repository. Step 4 - Learn about common DSpace customizations Step 5 - Refer to the DSpace documentation Step 6 - Still have questions?
Mathway | Math Problem Solver Requirements Once you understand the requirements, continue to the installation documentation. UNIX vs Windows If you are a Windows users, read how how Circos differes on UNIX and Windows. Perl You will need Perl to run Circos. Perl 5.8.x, or newer, is recommended. You can download Perl from perl.org, or as a package for your operating system from your vendor or distributor. Modules Additional code contributed by the Perl community (modules) is required to run Circos. In addition to the core modules that already ship with Perl, refer to the list of required modules. For a full list of modules, run > cd bin > . To test whether you have each module > cd bin > . True Type Fonts Your version of the GD module must be compiled with support for True Type fonts. Bitmap fonts For small text, bitmapped fonts are best - you can find many free fonts at DaFont. The Mini font set is an attractive alternative. These fonts are in True Type format, but have been designed to be displayed at a fixed resolution.
GED Viz, A Data Storytelling Tool | eagereyes I had the honor and pleasure to keynote an event in Berlin recently that introduced a new visualization tool to the world, GED Viz. What makes it stand out from other web-based visualization tools is its focus on particular data, and the ability to create not just individual views, but little stories. GED stands for Global Economic Dynamics, which explains where the motivation for the project actually came from: the need to show the underlying data when explaining global relationships based on the movement of goods, money, and people between countries. The visualization is essentially a chord diagram, showing the countries around a circle and connecting them with bands through the center. What interests me about the project more than the basic visualization is the ability to create little slideshows, or stories. When you open that slideshow in edit mode (by clicking in the lower right), you can create new slides and delete or rearrange existing ones.
Visualizing Linguistic Variation with LATtice The transformation of literary texts into “data” – frequency counts, probability distributions, vectors – can often seem reductive to scholars trained to read closely, with an eye on the subtleties and slipperiness of language. But digital analysis, in its massive scale and its sheer inhuman capacity of repetitive computation, can register complex patterns and nuances that might be beyond even the most perceptive and industrious human reader. To detect and interpret these patterns, to tease them out from the quagmire of numbers without sacrificing the range and the richness of the data that a text analysis tool might accumulate can be a challenging task. Once we have this data, however, how can we use it to compare texts, to explore how they are similar and how they differ? LATtice addresses this problem by producing multiple visualizations in tandem to allow us to explore the same underlying LAT data from as many perspectives and in as much detail as possible.
