"Να είσαι θερμοστάτης, όχι θερμόμετρο" είναι μια φράση που άκουσα πριν μερικά χρόνια από έναν guru του χώρου και μου έχει μείνει καρφωμένη στο μυαλό από τότε! Το θερμόμετρο είναι μια συσκευή η οποία μόνο καταγράφει δεδομένα, ενώ ένας θερμοστάτης μετατρέπει τα δεδομένα και σε ενέργειες. Αν καταφέρουμε να έχουμε περισσότερους "έξυπνους θερμοστάτες" στην διάθεση μας όταν αναλύουμε δεδομένα, θα μπορέσουμε να διαχειριστούμε και πολύ μεγαλύτερο όγκο αλλά και να επιταχύνουμε τις αντιδράσεις μας σε αυτά.

Parsing web sitemaps using JavaScript

Recently I came across an interesting project by Sean Thomas Burke called Sitemapper. This is a mini framework, which can be used to parse through sitemap XML files to get all included URLs. Such functionality is necessary when crawling through websites, as the sitemap (usually) holds an up-to-date list of all website URLs. In most cases this list should be enough when designing a crawler and you wouldn’t need to crawl manually the website and create a list of URLs. Sitemap parser: Sitemapper Sitemapper is a well-maintained and well-documented, open-source library offering the following features: Follows redirects Supports gzip sitemaps...

Tracking Pageviews in Analytics using page visibility (by Philip Walton)

I came across an interesting alternative approach from Philip Walton. He explains clearly why all websites cannot work with the default definition of a page view in Analytics and how we someone could start using the page’s visibility state (using the Page visibility API). Unfortunately this post was originally published in 2017 and still until today, even though Single Page Application (SPA) websites are widely used, we reply mostly on complicated implementations to virtually create page views for analytics tracking. Another alternative to this problem is to use an Event Driven Data Layer (EDDL), but I like the simplicity of...

Enterprise websites split across many regions and locales are huge, but every page matters.

Fighting pandemics using big data

I was very pleased to exchange and share some thoughts with Sotiris Kyriakidis from the Greek news agency “Praktoreio” on how big data can help the current battle against the Coronavirus (Covid-19). It’s the first pandemic (at least in my lifetime), where data scientists or just a data enthusiast can play an important part in how governments handle the Coronavirus crisis. I would be glad to hear your thoughts. (Unfortunately the interview is only available in Greek) Τα «big data» ως τεχνολογικό όπλο για την αντιμετώπιση ασθενειών Εμβόλια, φάρμακα, θεραπείες, έρευνα είναι μερικές μόνο από τις ανθρώπινες δραστηριότητες στον τομέα...
