Bringing Machshavah to Machshevim: A Mindful Approach to Technology in Jewis...forestfortrees
This document discusses the arguments for using technology in Jewish education. It argues that while technology can increase efficiency and possibilities, its use requires a mindful approach. Simply introducing new technologies into classrooms does not guarantee educational benefits. Educators must understand how to leverage technologies to connect lessons to their affordances and avoid "just-so" explanations that technology will automatically improve education. A thoughtful approach is needed to skillfully blend technology with deep understanding, ethical values, and community.
Freak Out, Geek Out, or Seek Out: Dealing with Tech Change and Customer Engag...David King
This document discusses how libraries can respond to changes in technology and customer engagement. It suggests that libraries should embrace a digital presence and focus on customer experience. Libraries need community managers, digital branch managers and other roles to engage patrons both inside and outside the library. The document provides examples of libraries interacting with patrons through social media, focus groups and visiting where patrons gather online. It emphasizes designing services around customers and improving customer journeys. Libraries should also gauge staff readiness for change and find champions to help lead transformations.
Il2008: Crafting The User-Centered LibraryCliff Landis
The document discusses approaches to adopting emerging technologies in libraries in a user-centered way. It advocates for trying new technologies quickly through a process of assessing user feedback and reflecting on successes and failures, rather than over-planning. Specific tips include using surveys, focus groups, observations and conversations to gather user input, and getting buy-in from administrators by highlighting data-driven results. The document stresses creating a culture of innovation where it's acceptable to fail fast and iterate based on what works best for users.
This document provides an overview of Arduino, an open-source electronics prototyping platform. It introduces (1) the Arduino Uno board and its features, including a microcontroller, digital and analog pins for input/output, and connections for power and communication; (2) Arduino programming using the C/C++ based IDE to write sketches with setup() and loop() functions; and (3) examples of Arduino projects and where to purchase Arduino boards and components.
The notion of allowing access to your website content and data via API's and other machine readable means is well embedded in geek circles.
This presentation aims to look at the non-technical reasons why these approaches are a good idea, arguing that it is time for Machine Readable Data (MRD) approaches to be better communicated to content owners, budget holders and other non-technical stakeholders.
The document discusses the importance of making content machine-readable so that it can be reused and accessed in different ways. It provides 10 reasons why organizations should adopt practices that allow computer systems to access and interpret their data, such as using microformats, RSS feeds, and APIs. These practices free up content so it is no longer locked into single websites and applications, making it easier to reuse and repurpose. The document advocates a focus on content over technology and argues that embracing machine-readable data will lead to benefits like lower costs, more ways to visualize and access content, and increased traffic over time.
Technology Planning for Libraries (BEST 2011)Michael Sauers
This document provides guidance on developing a technology plan for libraries. An effective plan should have SMART goals and include an executive summary, library description, challenges, current technology environment, emerging technologies, website evaluation, and recommendations. The recommendations section is the most important and should prioritize initiatives, describe the relevant categories, provide specific recommendations including costs and benefits, and recommended timeline. Developing the plan requires identifying stakeholders, assessing staff competencies, and inventorying current technologies. Resources for creating the plan are also provided.
Communication Strategies in a Library 2.0 EnvironmentLauren Pressley
The document discusses communication strategies in a library 2.0 environment. It suggests using a systematic ADDIE model of analysis, design, development, implementation, and evaluation for developing communication strategies. Various communication methods and tools are discussed, including blogs, wikis, social media, and podcasts. Effective positioning involves listening, participating in discussions, and following relevant streams of information.
The document provides a list of links to various free online tools for creating comics, recording audio, capturing screenshots, making slideshows and photostories, designing presentations, developing games and learning objects, collaborating online, editing webpages and images, converting file formats, organizing meetings, and more. The tools are intended to be helpful for students and teachers in developing projects, assessments and resources.
Up close and personal - Future of Digital 2010Rob Manson
This document discusses the emergence of the personal platform in 2010, as mobile devices, wireless speeds, screens, cameras, augmented reality, and wearable displays advance. It notes that by the 2000s, all the components for the next computing platform existed, and 2010 will bring "jedi computing" as these technologies converge. The personal platform will allow for always-on connectivity, enhanced access to information, hyper-social connectivity, and the ability to see multiple perspectives and capture rich digital histories. The conclusion asks what each person's personal platform will be like.
The document discusses designing holistic experiences that span both digital and physical channels. It recommends designing for the "space between" interactions by considering the full customer journey. Five principles are outlined for cross-channel design: convenient, connected, consistent, contextual, and cross-time. Five methods and tools are also presented: thinking in terms of services; sharing design work; starting with observations; embracing discomfort; and focusing on customer needs over specific solutions. The overall message is that customers experience brands through all touchpoints, so design must consider the integrated experience.

Sviluppatore PHP dal 2005 Utilizzo prevalentemente Symfony dal 2007 Dedico tempo alla community in vari modi: - faccio parte del consiglio direttivo del grusp che è l'associazione che organizza phpDay/jsDay e supporta altre associazioni a realizzare eventi in tutta Italia - uno dei fondatori del PUG Friuli - symfony: traduzione documentazione / bugs Nel tempo libero mi dedico al running
Non avendo già abbastanza impegni ora anche autore PHP Best Practices in anteprima al phpDay Il primo libro italiano di questo genere. Dalla community per la community. Gli autori fanno parte del GrUSP ed i temi trattati sono davvero interessanti. Mio capitolo dedicato al performance profiling delle applicazini PHP
Ci ho preso gusto... Da oltre due anni lavoro da casa Ho deciso di raccontare la mia esperienza Sto scrivendo questo libro
Punto di partenza: siti o applicazione le cui performance sono sono il massimo. Posso scommettere un caffè che almeno 1-2 persone per ogni fila di sedie si è trovato in una situazione del genere. In situazioni del genere molto spesso il database è il primo elemento verso cui si punta il dito, a volte questo è vero anche se effettivamente lui fa quello che gli si dice di fare... Si può quindi affermare che si utilizza il db in modo illecito, non è lui ad essere cattivo a prescindere ma lo sviluppatore che ha sbagliato qualcosa....
Avere un sistema più performant e grazie ad alcuni accorgimenti che permettono di sfruttare meglio le grisorse a disposizione, in particolare la memoria, oltre che utilizzare gli strumenti in modo corretto e non snaturandoli L'obiettivo è quello di integrare lo stack a disposizione senza imporre migrazioni complete PICCOLE MODIFICHE → GRANDI RISULTATI
Il caso più tipico è quello di una nuova applicazione in cui... Tutto fatto sfruttando il db tanto il traffico è basso e la mole di dati da gestire è piccola. Ogni operazione che richiede di scrivere/leggere dati viene fatta con il database Numeri piccoli, tutto funziona
Succede poi che si ottiene il successo ipotizzato o succede l'inaspettato ed il sito viene sommerso dalle visite che inevitabilmente rendono il servizio inaccessibile. Ciò che funzionava per 1000 utenti non funziona più per 10000...ed inevitabilmente fanno la loro comparsa errori di questo tipo a seconda delle configurazione dello stack... 503 service unavailable 504 gateway timeout
Semplificando parecchio il discorso, il collo di bottiglia principale, parlando di limiti fisici, è rappresentato dai tempi di seek dei dischi su cui il db risiede per posizionare la testina sul punto esatto del disco per leggere le informazioni.. Questo problema diventa più marcato man mano che la quantità di dati aumenta e che il caching effettivo diventa impossibile.
Ovviamente il primo pensiero è quello di mettere mano al portafoglio per scalare l'architettura verticalmente (male) od orizzontalmente (bene) andando inevitabilmente ad aumentare la complessità del sistema. La figura non tecnica dice “se serve facciamo spendere il cliente”. Migrare completamente verso altri prodotti che reputiamo più performanti.
Prima però forse è il caso di provare a sfruttare gli strumenti già a disposizione in modo migliore, puntando sui loro punti di forza e non pesando sui loro punti deboli... Introdurre strumenti a basso impatto per quanto riguarda lo stack Che integrano e non richiedono una migrazione completa di parti dell'applicazione
Area ad accesso rapido sia in lettura che scrittura, operazioni eseguite a basso costo. Inoltre è SEMPRE già a disposizione. Ovviamente ha dei limiti, primo fra tutti non è persistente quindi OCCHIO a cosa ci fate lì dentro! Ok però c'è bisogno di qualcosa che ci permetta di utilizzarla facilmente perchè da buoni sviluppatori siamo pigri...
Memcached Sistema distribuito di caching in memoria degli oggetti. Key-value store per stringhe e oggetti dalla natura generica utilizzato principalmente per ottimizzare le performance di applicazioni dinamiche alleviando il carico sui database. Redis advanced key-value store. often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets. Aggiunge la persistenza dei dati. Vediamo dei casi d'uso...
Gestione ed erogazione banner. Poche scritture, contenuti cambiano con bassa frequenza . Molte letture perché è necessario far ruotare le creatività e non è possibile mettere in cache. Spostare tutto in memoria. L'anno scorso verso luglio -40M query/giorno con questo scherzetto. Grafico in picchiata della cpu dei db slave...purtroppo non l'ho trovato. MEMCACHED
Impression, views, click, sondaggi... Tutti write-intensive task per il db. Il segreto è quello di incrementare il valore di una chiave per un certo periodo per poi fare scritture ad intervalli regolari. VEDERE COMANDI PER SCRITTURA SICURA MEMCACHED / REDIS
Caso classico per avere un punto centralizzato in cui verificare se l'utente è online o meno. Il lifetime di una chiave calza a pennello e leggendo dalla memoria non devo fare operazioni dispendiose sul db ad ogni visualizzazione. Posso inoltre rinnovare il lifetime dopo l'esecuzione di particolari azioni che mi assicurano la presenza dell'utente. MEMCACHED
Tutti i casi del tipo - ultimi commenti inseriti dagli utenti - ultimi visitatori del tuo profilo - ultimi qualcosa... Non ha senso dover ordinare dati se ci servono semplicemente nell'ordine in cui sono stati inseriti. LISTE: inserisco commenti con LPUSH al momento della loro creazione, posso impostare dimensione massima LTRIM 0 100, leggo dalla lista ed eventualmente fall back sul db se non ci sono abbastanza elementi REDIS
Esempio comune difficile da modellare con buone prestazioni su DB non in memoria: prendere un elenco di elementi, ordinarli in base ad un punteggio, aggiornato in real time, con molti aggiornamenti ogni secondo... Pensate ad un gioco online per esempio dove - mostrare la classifica dei primi 100 - mostrare la posizione del singolo utente Queste operazioni sono banali utilizzando gli INSIEMI ORDINATI (SORTED SETS) anche se si ha a che fare con milioni di utenti e milioni di nuovi punteggi ogni minuto.
