Data loss comes in all shapes and sizes, from an accidentally deleted document to a catastrophic server failure that wipes out a critical database. Modern businesses are absolutely reliant on data, and on the infrastructure they use to store, process, and access that data. The grim reality is that those systems and the people who use them are fallible. Most business owners are aware that backups are important, but few have a full disaster recovery plan in…Continue

Black hat data science consists of techniques designed to fool existing algorithms (Google search, Amazon rankings, and so on), compromising or tampering with the metrics -- especially ratios -- that they rely on, without actually physically touching or altering data stored in their databases. It exploits flaws in these algorithms, and it also relies on reverse engineering, to achieve its goal. So black hat data science is different from traditional hacking,…Continue

Every business depends on data. For both the teen who mows lawns at the weekend and globe-spanning internet giants like Google, data is vital.
It might be addresses written on a piece of paper or petabytes of information stored on thousands of powerful servers. If it’s lost, the business loses money, time, and the respect of its customers.
Most business leaders…Continue

We’re all familiar with data visualizations—word clouds, pie charts, pivot tables—but how does one put enquiries in paint? Patty Haller, a landscape artist from Seattle WA, may have figured that out. Her training in finance at University of Washington and traditional oil painting at Gage Academy of Art raised more questions than it answered.…Continue

There have been many articles written and talks given over the last several years on abandoning the Enterprise Data Warehouse (EDW) in favor of an Enterprise Data Lake with some passionately promoting the idea and others just as passionately denying that this is achievable. In this article, I would like to take a more pragmatic approach to the case and try and lay down a process that enterprises should consider for a data management architecture.
The focus is on data lakes for…Continue

Technology always takes a dominant position in economy and society. Millions of people therefore found their careers, and many others have even dived into a completely different field just for entering this industry. Even so, enterprises are still trying hard to seek for skilled programmers; when the right one shows, companies would even raise HR budgets. Technology is continuing to infiltrate into new platforms and industries, hence, to maximize one’s profit potentials, also for…Continue

This famous statement -- the six degrees of separation -- claims that there is at most 6 degrees of separation between you and anyone else on Earth. Here we feature a simple algorithm that simulates how we are connected, and indeed confirms the claim. We also explain how it applies to web crawlers: Any web page is connected to any other web page by a path of 6 links at most.
The algorithm below is rudimentary and can be used for simulation purposes by any programmer: It does not even…Continue
