What is DSLR?

A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The traditional alternative would be to have a viewfinder with its own lens, hence the term “single lens” for this design. By using only one lens, the viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera’s sensor. A DSLR differs from non-reflex single-lens digital cameras in that the viewfinder presents a direct optical view through the lens, rather than being captured by the camera’s image sensor and displayed by a digital screen.

DSLRs largely replaced film-based SLRs during the 2000s, and despite the rising popularity of mirrorless system cameras in the early 2010s, DSLRs remain the most common type of interchangeable lens camera in use as of 2017.

Personal data – What is it?

Personal data is information and assessments that can be linked directly or indirectly to an individual, i.e. the data subject.

 

Personal data includes name, gender, age, address, phone number (for personal or work use), credit card transactions, social security number etc. But we must also remember that, for example, IP addresses and encryption keys in many cases can be linked to individuals, and thus may be considered as personal data. Personal data also includes behavioral information such as where you shop, what you watch etc (often referred to as profiling).

 

Sensitive personal data is information on race or ethnicity, political, philosophical and religious beliefs, health conditions, sexuality, membership in unions, criminal matters. In addition, it includes genetic and biometric information when General Data Protection Regulation (GDPR) comes into effect on May 25, 2018.

Electronic data interchange

Electronic data interchange (EDI) is an electronic communication method that provides standards for exchanging data via any electronic means. By adhering to the same standard, two different companies or organizations, even in two different countries, can electronically exchange documents (such as purchase orders, invoices, shipping notices, and many others). EDI has existed for more than 30 years, and there are many EDI standards (including X12, EDIFACT, ODETTE, etc.), some of which address the needs of specific industries or regions. It also refers specifically to a family of standards. In 1996, the National Institute of Standards and Technology defined electronic data interchange as “the computer-to-computer interchange of strictly formatted messages that represent documents other than monetary instruments. EDI implies a sequence of messages between two parties, either of whom may serve as originator or recipient. The formatted data representing the documents may be transmitted from originator to recipient via telecommunications or physically transported on electronic storage media.” It distinguishes mere electronic communication or data exchange, specifying that “in EDI, the usual processing of received messages is by computer only. Human intervention in the processing of a received message is typically intended only for error conditions, for quality review, and for special situations. For example, the transmission of binary or textual data is not EDI as defined here unless the data are treated as one or more data elements of an EDI message and are not normally intended for human interpretation as part of online data processing. EDI can be formally defined as the transfer of structured data, by agreed message standards, from one computer system to another without human intervention.

What is personal data?

Personal data can be observed, inferred and/or derived.

Personal data is a piece of information or assessment of it that can be linked to you as an individual. It includes name, personal identity number, address, telephone number, E-mail, iris pattern, credit card information etc.

Sensitive personal data includes information on race or ethnicity, political, philosophical and religious beliefs, health conditions, sexuality, membership in associations or criminal matters.

Observed personal data about your behavior like “What and how do you shop?” – “What do you watch on TV?” – “Where are you going?” – “What are you searching for on the Internet?”

Growth hacking

growthhackingGrowth hacking is a marketing technique developed by technology startups which uses creativity, analytical thinking, and social metrics to sell products and gain exposure. It can be seen as part of the online marketing ecosystem, as in many cases growth hackers are simply good at using techniques such as search engine optimization, website analytics, content marketing and A/B testing which are already mainstream.

Growth hackers focus on low-cost and innovative alternatives to traditional marketing, e.g. utilizing social media and viral marketing instead of buying advertising through more traditional media such as radio, newspaper, and television.

Growth hacking is particularly important for startups, as it allows for a “lean” launch that focuses on “growth first, budgets second”. Facebook, Twitter, LinkedIn, AirBnB and Dropbox are all companies that use growth hacking techniques.
