Afrika’da her sabah bir ceylan uyanır
En hızlı aslandan daha hızlı koşması gerektiğini,
Yoksa ona yem olup öleceğini bilir.
Afrika’da her sabah bir aslan uyanır…
En yavaş ceylandan daha hızlı koşması gerektiğini,
Yoksa açlıktan öleceğini bilir…
This document discusses Apache Spark machine learning (ML) workflows for recommendation systems using collaborative filtering. It describes loading rating data from users on items into a DataFrame and splitting it into training and test sets. An ALS model is fit on the training data and used to make predictions on the test set. The root mean squared error is calculated to evaluate prediction accuracy.

In the start-up culture of the 21st century, we live by the motto “move fast and break things.” What if what gets broken is society*?
how can we build data products and services that use data ethically & responsibly?
how do companies take a data (science) project from lab to production successfully?
Systems that can explain their decisions.
how can we interconnect the web of data, its agents, and their decisions to enlarge the pie?
Your data is getting bigger while your boss is getting anxious to have insights! This tutorial covers Apache Spark that makes data analytics fast to write and fast to run. Tackle big datasets quickly through a simple API in Python, and learn one programming paradigm in order to deploy interactive, batch, and streaming applications while connecting to data sources incl. HDFS, Hive, JSON, and S3.
Slides are from my welcome speech to the 2014-2015 Freshmen at Computer Science Department of Istanbul Sehir University. I emphasize the command of English, building trust, and being self-organized as three key takeaways.
This document discusses the need for data science skills and proposes a curriculum to address the skills gap. It notes that the web has evolved from static HTML to user-generated content and now machines understanding information. Current jobs require data analysis, idea generation, and hypothesis testing skills. A study found enterprises have major skills gaps in mobile, cloud, social and analytics technologies. The proposed curriculum aims to directly teach needed skills while keeping students engaged. Core classes focus on algorithms, systems, architecture, and machine intelligence. The curriculum is designed to bridge undergraduate and graduate programs and use Python to keep students engaged with hands-on projects. A future data science graduate program is outlined focusing on data engineering, networks, visualization, scalable systems, big data
Open source refers to the process by which software is created, not the software itself. The open source process involves voluntary participation where anyone can contribute code freely and choose what tasks to work on. It relies on collaboration between many developers worldwide who are motivated to scratch an itch, avoid reinventing the wheel, solve problems in parallel, and leverage the law of large numbers through continuous beta testing. Documentation and frequent releases are also important aspects of open source development.
This document summarizes Week 3 of a Python programming course. It discusses introspection, which allows code to examine and manipulate other code as objects. It covers optional and named function arguments, built-in functions like type and str, and filtering lists with comprehensions. It also explains lambda functions and how and and or work in Python.
This document provides a summary of Week 2 of a Python programming course. It discusses dictionaries, including defining, modifying, and deleting dictionary items. It also covers lists, such as defining and slicing lists, as well as adding, searching, and deleting list elements. Finally, it introduces tuples as immutable lists and discusses variable declaration and string formatting in Python.
This presentation outlines two main startup/business development models: product development model, customer development model. The right methodology is to use both at the same time with constant feedback and learning.
The document discusses the potential of group buying deals and collective discounts, noting that people are more likely to purchase items if they feel they are getting a good deal as part of a group. It proposes that a company can leverage their user base and merchant relationships to create dedicated group deal pages and use marketing techniques like emails and pop-ups to promote the deals in order to benefit both consumers and merchants through a commission-based sales model.
VMware ESX Server provides a virtualization platform for mission-critical environments. It utilizes hardware virtualization to present virtual machines with direct access to resources, allowing multiple guest operating systems to run in isolation on a single physical server. ESX Server offers a bare-metal architecture for high performance, as well as granular resource management and hardware support from major vendors to maximize utilization and flexibility.
3. Mor İnek ~ Niçin?
Mor İnekle tanışmak için, özel hayatınızda ya da
kişisel hayatınızda “Niçin?” sorusunu sormayı
alışkanlık haline getirmeliyiz.
Yapmadığımız çoğu şeyin aslında özel bir sebebi yok.
Yapmadığımız çoğu şeyin sebebi:
korku
veya tembellik,
veya "Niçin?" sorusunu az sormuş olmak.
5. “İyi”den “Mükemmel”e
Ne değil, Kim sorusu
ile işe başlayın.
Şartlar değişir.
10 km sonra başka yöne
gitmeniz gerektiğinde; diğer insanlar o
otobüse sadece gittiği istikamet için
binmişlerse, tehlike çanları çalar.
6. Motivasyon
Doğru kişilerin motive
edilmeye ihtiyaci yoktur.
Doğru kişiler motivedir
zaten.
Harikalar yaratacağı beklenen
bir takımın parçası olmak
kadar tatmin edici bir şey yoktur.
7. Kolay gelsin ;-)
Yanlış insanlarla, ağzınızla
kuş tutsanız bile olmaz.
Doğru yönde gidiyor
olabilirsiniz. Ama harikalar
yaratamazsınız. Harika
vizyon, orta direk şabanlarla,
orta sonuçlar dogurur.
9. Kurumsal Atlet
İnsan dört farklı kapasiteye sahiptir.
En temelde fiziksel kapasite, yani sağlık vardır.
Bunun üzerinde zihinsel kapasite gelir, yani sağlam kafa,
sağlam vücutta; sağlam vücut, sağlam kafada bulunur.
Zihinsel kapasitenin üzerinde ise duygusal kapasite vardır.
Üretken olmak için, motivasyon; motivasyon için de
duygusal olarak stabil olmak gerekir.
Ama aslolan, hayatta maraton koşturacak olan, ruhsal
kapasitedir; ve en tepededir bu piramitte. Ruhsal kapasite,
hayatı anlamlı kılabilme gücüdür.

Amaçlar önemlidir, Para önemlidir.
Fakat para bir amaç değil araçtır.
