Die Informationsvielfalt im Internet ist nahezu grenzenlos: fast alles ist tagesaktuell und st\u00e4ndig verf\u00fcgbar. Leider gibt es nur f\u00fcr einen kleinen Teil dieser Daten \u00f6ffentlich verf\u00fcgbare APIs. Ein Webcrawler kann diese L\u00fccke schie\u00dfen. Er liest \u00f6ffentlich verf\u00fcgbare Informationen, verarbeitet sie und wandelt sie in ein maschinenlesbares Format um. Damit werden viele praxisnahe Softwareanwendungen erst m\u00f6glich.
\r\n\r\nDieser Vortrag richtet sich an alle, die sich f\u00fcr den Aufbau und Funktionsweise eines solchen Webcrawler interessieren.
\r\n\r\nDie Basis-Funktionen eines Webcrawler sind schnell erkl\u00e4rt und einfach implementiert: Man l\u00e4dt den Inhalt einer Seite, extrahiert die ben\u00f6tigten Daten und verwendet sie nach Belieben. Aber es gibt noch einige Details, auf die man R\u00fccksicht nehmen sollte. Ein schlecht gebauter Bot ver\u00e4rgert schnell die Server-Administratoren und man wird als b\u00f6swilliger Angreifer beschimpft.
\r\n\r\nDer Vortrag geht auf wichtige Details beim Bau eines Webcrawler ein und zeigt Herangehenweisen, um mit der riesigen Datenflut fertig zu werden, die, wenn man es eben richtig macht, aus dem Netz frei extrahiert werden kann.
\r\n\r\nRobots.txt, Parallelisierung, cURL, HTML-Parser, Regular-Expression, PhantomJS\u2026 sind nur ein paar Schl\u00fcsselw\u00f6rter auf die der Vortrag eingeht. Aber vor allem k\u00f6nnen die Zuh\u00f6rer von den gro\u00dfen Erfahrungen eines lokalen Unternehmens profitieren, welches es zum Marktf\u00fchrer in ganz Deutschland geschafft hat.
\r\n\r\nDer Vortrag enth\u00e4lt einige Live-Demonstrationen, in denen gezeigt wird, wie leicht das Internet als freie Informationsquelle genutzt werden kann und das man nicht immer auf kostenpflichtige APIs angewiesen ist, um Daten strukturiert zu erhalten. Meistens besteht nicht einmal die M\u00f6glichkeit, Daten in einem maschinenlesbarem Format abzurufen. In diesen F\u00e4llen schlie\u00dft ein Webcrawler die L\u00fccke
\r\n\r\nKurz gesagt: Dieser Vortrag richtet sich an diejenigen Zuh\u00f6rer, die sich f\u00fcr eine sichere, effiziente und vorallem freie M\u00f6glichkeit interessieren, das Internet als Datenbasis zu nutzen.

The presentation will explain recent conceptual and technical changes to the Fossology project.","description":"For the analysis of open source licenses, the Fossology software has been extended in the recent months with a three-way strategy in mind:\r\n\u2022\tProviding efficient scan approaches to identify licenses in the open source package: Identifying licenses in open source software can be, depending on the actual project, a tedious task: Today many variants and versions of open source licenses are published: The technical challenge lies in precisely determining the particular variant / version of license and exclude other possibilities with lowest manual inspection effort as possible.\r\n\u2022\tNevertheless, manual inspection is inevitable, for example for new, unknown or author-specific licenses. This represents also the rationale with the recently updated SPDX standard, which distinguishes between found and concluded license when it comes to determine the actual license condition. As a result, the next challenge to solve is: How to provide an efficient UI when potentially manually dealing with thousands of files with license information?\r\n\u2022\tReuse of license decisions can lead to a much lower manual inspection effort for future scans and thus is key for easier open source adoption. However, the need to carefully reuse applying decisions and leaving open points for clarification requires a conservative strategy of reuse on the other hand.\r\nThe Fossology open source software has been evolved to cover the above, which includes new approaches and a number of technical adaptations. The presentation will also cover collaboration aspects of contributing to the Fossology community and an outlook of evolving license analysis in the future.\r\n","do_not_record":false,"persons":[{"id":1095,"full_public_name":"Michael C.

Der Workshop stellt L\u00f6sungsans\u00e4tze auf Basis von Icinga 2/Icinga Web 2 vor, die helfen verschiedene Bereiche eines Data Warehouse zu \u00fcberwachen und zu kontrollieren.","description":"Schon w\u00e4hrend der Entwicklung eines Data Warehouse ergeben sich Fragestellungen wie \r\nNEU: Ab ca. Sonntag-Nachmittag wird's einen Tarball (v1.0) mit jenen Unterlagen, Materialien und erzeugten Dokumenten geben, die ich w\u00e4hrend des Workshops vorgestellt habe. Inklusive des Makefiles zum (halb-)automatischen Erzeugen der Ausgabe-Dateien. Siehe README im Tarball. In der Spalte rechts unter "Files" schauen.
NEU: In ca. zwei, drei Wochen wird's dann hoffentlich noch einen weiteren Tarball (v1.1) geben mit Korrekturen und \u00dcberarbeitungen.
Jeder Software-Entwickler sollte sich darum k\u00fcmmern, dass seine Programme durch eine ordentliche Dokumentation abgedeckt sind. Aber viele Programmierer erledigen das \u00e4u\u00dferst ungern. Darum ist die Erstellung von Dokumentation h\u00e4ufig ein "Stiefkind" von Projekten.
\r\nViele Software-Benutzer w\u00fcrden gerne etwas zur Dokumentation beitragen und dadurch zu Committern werden -- und manche tun es schon, oft sogar im Zusammenhang mit mehreren Projekten. Aber dann verwenden unterschiedliche Projekt vielleicht jeweils andere Formate und Werkzeuge zum Schreiben: OpenDocument, HTML, LaTeX, DocBook, ...
\r\nW\u00e4re es nicht viel besser, alles in reinem Text zu schreiben? Und dann aus diesem Text automatisiert das End-Format zu erzeugen, welches man verwenden m\u00f6chte? Oder gar alle m\u00f6glichen Endformate?
\r\nMit der einfachen Text-Auszeichnungssprache Markdown ist es m\u00f6glich. Zum Konvertieren in beliebige Zielformate verwendet man das Kommandozeilen- Tool pandoc. Zur Automatisierung ein Makefile...
Da Pandoc auch ausgezeichnet mit CSL-Dateien (Citation Style Language) umgehen kann, eignet sich Markdown auch hervorragend f\u00fcr Studien-, Diplom-, Doktor- und andere wissenschaftliche Arbeiten, denn es erzeugt automatisch komplette Literaturverzeichnisse, formatiert sie und f\u00fcgt sie ins fertige Dokument ein.
","description":"Markdown ist ein derma\u00dfen einfaches Textauszeichnungsformat, dass man bei Kenntnis von ca. 12 verschiedenen, einfachen, sehr intuitiv zu erlernenden Formatierungs-Regeln bereits sehr anspruchsvolle Dokumente zustande bringt -- und zwar in allen m\u00f6glichen Formaten, und in sehr vielen anpa\u00dfbaren Stilen.
\r\npandoc --to=html erzeugt HTML-AusgabeWer komplexere Formatierungen ben\u00f6tigt, kann innerhalb des Markdown-Quellcodes auch HTML-Schnipsel verwenden. pandoc gibt diese beim \u00dcbersetzen 1:1 in das Zielformat weiter. (Falls das Ziel-Format LaTeX oder PDF ist, kann man sogar LaTeX-Schnipsel einbetten.)
Die Konvertierung des Markdown-Quelltextes in das gew\u00fcnschte Dokumenten-Format erfolgt durch das Kommandozeilen-Tool pandoc. Dabei stehen eine ganze Reihe unterschiedlicher Ziel-Formate zur Wahl: erw\u00e4hnt seien hier nur Open/LibreOffice ODT, MS Word DOCX, LaTeX, DocBook, HTML, PDF, EPUB, EPUB3, ConTeXt und MediaWiki.
Das endg\u00fcltige Aussehen der Dokumente l\u00e4sst sich dadurch beeinflussen, dass man eigene CSS-Dateien, Vorlagen- oder Referenz-Dokumente einbindet. Ansonsten erh\u00e4lt man schlichte Dokumente mit den jeweils voreingestellten Stilen. Beim Bau eigener CSS-Stile sind einem versierten Anwender so gut wie keine Grenzen gesetzt, bei der Erstellung eigener Vorlagen und Referenzen gibt es ebenfalls erstaunlich viele M\u00f6glichkeiten.

\r\nDenn dabei wird's nicht viele Folien geben, sondern fast ausschlie\u00dflich Live-Vorf\u00fchrung.

Roberta aims at engag- ing and motivating girls and boys to take a sustained long-term interest in information technology, technology and the natural sciences (STEM). For more than ten years, this underlying initiative successfully enabled girls and boys to explore the world of robots and to learn about computer science and technology in a playful way. With more than 30.000 participating children and young people in over 600 documented Roberta courses a year - Roberta has become a permanent fixture in the German education landscape.\r\nThe aim of Open Roberta is to overcome technical and professional barriers for teachers and students alike at home or in the classrooms. The free to use cloud-based Open Roberta Lab consists of graphical programming tools that enable beginners to seamlessly start coding without long-winded system installations, setups or additional technology getting in the way.\r\nIn its first available release, Open Roberta enables children and adolescents to program LEGO Mindstorms EV3 robots in the beginning. A variety of different visual programming blocks are provided to interact with motors, sensors and the core of LEGO robots, the EV3-Brick. Upcoming software releases are aiming at a broader online programming support for additional educational hardware (like robots, toys, etc.). The necessary machine code translations are part of our new invented NEPO programming language which is build into Open Roberta.\r\nThe created technology and its concepts are free to use for anyone and are available as open source. In a first step, the development team at the Fraun- hofer Institute for Intelligent Analysis and Information Systems reached out to teachers, IT and education experts within the partnering Roberta network as well as to universities and their students to involve them in the develop- ment work. In the ongoing second step, the open-source community has been opened to all interested parties and programmers. By doing that Roberta still follows its main mission namely the encouragement of female newbies in order to help them becoming role models for the next generation of pro- gramming experts.\r\nThe presentation will address current limitations of available classroom pro- gramming solutions and is going to showcase Open Robertas online coding capabilities. A further aspect of the talk will be the introduction of the NEPO abstraction language as a core concept for upcoming hardware com- munication.","description":"","do_not_record":false,"persons":[{"id":1067,"full_public_name":"Markus Ketterl"}],"links":[{"url":"http://www.open-roberta.org","title":"Open Roberta"},{"url":"http://www.open-roberta.org","title":"Roberta"},{"url":"http://www.iais.fraunhofer.de","title":"Fraunhofer IAIS"}]},{"id":1515,"guid":"68942be0-cb7d-4460-ac03-0ee7c1b18e20","logo":"/system/logos/1515/medium/logo.png?1430653672","date":"2015-08-23T11:15:00+02:00","start":"11:15","duration":"01:00","room":"HS 3","slug":"froscon2015-1515-a_solution_to_the_backup_inconvenience","title":"A Solution to the Backup Inconvenience","subtitle":"Fast, Secure and Efficient Backups with \"restic\"","track":"other","type":"lecture","language":"en","abstract":"Secure and efficient backups can be cumbersome. \"restic\" is a new, easy-to-use, very fast backup application that does deduplication and crypto right.
