Code generates business value when it runs not when we write it.
We must know how our code perform at runtime, how it interacts with the infrastructure, how our customers are using it to give them the opportunity to give use more money.
Set SLAs, measure them, reach them and move forward to increase the business value of our software.

Abstract: Advance payment systems represent a pricing innovation, in which companies predict customers' future consumption for the following year and then bill a series of monthly, uniform advance payments. Any difference between predicted and actual consumption gets settled at the end of the year with a refund or extra payment. Companies thus gain earlier access to funds and lower risk of customer defaults; customers benefit from predictable monthly payments. However, customers' reactions to a refund or extra payment sequence in an advance payment system remain unclear. Three theoretical lenses offer predictions about customers' advance payment system preferences: prospect theory, with a focus on silver lining and hedonic editing principles; mental accounting; and the value of sequences. Using three empirical studies with survey and billing data of more than 20,000 customers to examine their reactions to refunds and extra payments, this paper reveals that receiving a refund reduces customers' price awareness, increases their recommendation likelihood, and reduces churn and tariff switching, as long as the refund is not too high. The findings illustrate both the consequences and the boundary conditions of the silver lining principle with large-scale field studies.

ICQ was an early instant messaging client first launched in 1996 by Mirabilis. It allowed users to be interconnected online when previously people were only connected to the Internet individually. ICQ grew to have over 31 million users before being acquired by AOL in 1998 for $407 million. It introduced many innovative features including offline messaging, multi-user chats, file transfers, games and a searchable user directory. Later versions added notes, reminders, skins support, free SMS messaging, and voice/video calling capabilities.

GlusterFs: a scalable file system for today's and tomorrow's big dataRoberto Franchini
Roberto Franchini gave a presentation on GlusterFS, an open source, scalable distributed file system. GlusterFS allows storage to be scaled out by adding more servers with disks. It uses a flexible peer-to-peer architecture with data distributed across server bricks. Franchini discussed how his company implemented GlusterFS to store large indexes for information extraction tasks, scaling from 4TB to 28TB as storage needs grew. He provided recommendations on best practices like dedicated servers, same-sized bricks, and planning for future expansion.
Gluster FS is a distributed file system that can scale to support large "Big Data" workloads. It uses commodity hardware and runs on Linux servers. Data and metadata are distributed across server nodes and storage bricks to provide fault tolerance and high performance. Clusters can be expanded elastically by adding additional servers and storage. The system was implemented to address the need for scalable storage to support indexing and analytics of large document collections totaling hundreds of gigabytes per month.
This document summarizes a presentation about using Redis for duplicate document detection in a real-time data stream. The key points covered include:
- Redis is used to map external document IDs to internal IDs and cache these mappings to detect duplicates efficiently
- Lua scripting is used to generate IDs and check for duplicates in an atomic way
- Redis data structures like hashes and counters help count documents and store metadata efficiently
- A production deployment involved a single Redis server handling 70M keys and 10GB of RAM, with replication for high availability

The document discusses OrientDB, a multi-model database that combines document and graph functionality. It provides an overview of key OrientDB concepts like data models, schemas, indexing, and spatial and full-text search capabilities. Examples are given of modeling a Twitter graph using OrientDB classes, properties, indexes and relationship types. The document concludes with information on getting started with OrientDB.
Java application monitoring with Dropwizard Metrics and graphite Roberto Franchini
This document discusses using Dropwizard Metrics and Graphite for Java application monitoring. It provides an overview of systems monitoring with Collectd and Graphite, and the need for application monitoring. Dropwizard Metrics is introduced as a library for instrumenting Java applications to collect metrics like counters, gauges, histograms and timers. These metrics can be exported to Graphite for visualization in Grafana dashboards. Demo code shows instrumenting an application with Dropwizard Metrics and reporting to Graphite. The document emphasizes correlating application and system metrics for tasks like bottleneck discovery and SLA monitoring.
Optimal Pricing: Understanding Differences between Structural Models and Redu...Bernd Skiera
The document summarizes Bernd Skiera's 2010 article on the differences between structural and reduced-form models in improving pricing decisions. Structural models use economic theory to model demand, costs, competition and estimate price responses. Reduced-form models directly estimate price-response functions from historical data without an underlying economic framework. Skiera finds that structural models provide more accurate predictions of pricing decisions under different market conditions compared to reduced-form models.

Hier sind Folien, die ein wesentliches Ergebnis des folgenden Beitrags (in deutscher Sprache) zusammenfassen:
Skiera, Bernd / Hinz, Oliver / Spann, Martin (2015), "Social Media and Academic Performance: Does Facebook Activity Relate to Good Grades?", Schmalenbach Business Review, Vol. 67, Issue 1, 54-72
We analyze how Facebook use and students’ social network positions within it relate to their academic performance. We use a unique data set obtained from a survey of students’ perceptions, actual Facebook connections to measure social network positions, and objective grades provided by the university registrar to measure academic performance. We find that Facebook activities during class relate negatively to academic performance, that students located in densely connected subnetworks earn better grades, and that in contrast to female students, male students benefit from a general use of Facebook, particularly if they are highly connected.

These slides that describe the content of the paper: Hinz, Oliver / Skiera, Bernd / Barrot, Christian / Becker, Jan (2011), "An Empirical Comparison of Seeding Strategies for Viral Marketing", Journal of Marketing, 75 (November), 55-71.
Seeding strategies have strong influences on the success of viral marketing campaigns, but previous studies using computer simulations and analytical models have produced conflicting recommendations about the optimal seeding strategy. This study compares four seeding strategies in two complementary small-scale field experiments, as well as in one real-life viral marketing campaign involving more than 200,000 customers of a mobile phone service provider. The empirical results show that the best seeding strategies can be up to eight times more successful than other seeding strategies. Seeding to well-connected people is the most successful approach because these attractive seeding points are more likely to participate in viral marketing campaigns. This finding contradicts a common assumption in other studies. Well-connected people also actively use their greater reach but do not have more influence on their peers than do less well-connected people.
The document discusses Public Service Enterprise Group's (PSEG) outlook and growth opportunities. It summarizes that PSEG has a diverse set of assets well-positioned to capitalize on opportunities arising from issues like capacity constraints, environmental regulations, and New Jersey's Energy Master Plan. Near-term growth opportunities could increase earnings 15-37% in 2007-2008, while longer-term opportunities exist in areas like nuclear expansion, renewable investments, and capital redeployment. Managing risks prudently provides stability to support strong earnings and cash flows.

18. Sentit, Els treballs de recerca han estat un dels punts forts d’un sistema educatiu sovint massa qüestionat, no podem entrar a valorar les diferents dinàmiques que es realitzen en aquest tema als IES de la comarca, alguns d’ells realitzen una assignatura de metodologia del TR, d’altres no, amb molts tutors implicats o pocs, treballs en grup o individuals. Etc. Però una de les realitats visibles dels darrers anys, ha estat la promoció i difusió interna dels TR més destacats per part dels propis IES. Estem segurs que darrera de cada actuació d’aquestes característiques s’hi pot veure la voluntat de reconeixement de la feina ben feta per part del professorat i alumnes que han intentat aplicar els coneixements i metodologies adquirides al llarg dels anys d’escolaritat. En aquest marc, podem observar en diferents articles de premsa com molts ajuntaments i IES venen organitzant diferents premis interns, al marge dels premis que puguin haver-hi a tot el territori nacional. Des del Servei educatiu de l’Alt Empordà (SEAE) volem recollir aquest testimoni i aventurar-nos a organitzar el Primer Fòrum de Treballs de Recerca de la comarca seguint l’empremta del que ha suposat l’organització d’aquest fòrum en altres comarques de Catalunya. Creiem que la proliferació d’aquestes dinàmiques de difusió de la feina ben fetadels treballs de recerca de cara al. Creiem que val lapena aprofitar la bona experiència d’altres comarques i portar-hi a la nostra. En aquest cas es tractaria de donar suport a l’intercanvi de idees, entre. Es sostenible en l’espai, i temps, el volum de centres ens o permet acotar força i fer-ho sostenible. Alt Empordà
