  • by defining a description template that included among the rest: Known uses. Sample code (as opposed to a typical algorithm which were often described in plain English and perhaps a few sketchy lines of pseudo-code). Collaboration (A description of how classes and objects used in the pattern interact with each other). Consequences (results and side-effects). Related patterns.
  • Would a 2009 catalog of the 23 classic design patterns look much different? According to the authors of Design Patterns: Elements of Reusable Code, the answer is no.
  • The authors would reclassify certain patterns and omit a few of the original patterns but the design and implementation would remain pretty much the same: "We have found that the object-oriented design principles and most of the patterns haven't changed since then" says Erich Gamma. You can't escape the feeling that patterns are frozen in time

  • In the meantime, in the C++ world the tide has turned towards a completely different paradigm known as generic programming (and to some extent, functional programming). Instead of plain classes and a complex inheritance chain, C++ these days uses templates, meta-programming and static type checking. The C++ Standard Library is the most prominent showpiece of the generic and functional programming idioms.
  • Over-engineering is another source of criticism. Programmers who become acquainted with patterns are often tempted to solve every problem using a pattern, even when a much simpler solution would probably be a better choice.

    APK offers a broad portfolio of SpO2 sensors, including both reusable and versions for different applications and Patient categories. The principle of pulse oximetry was developed by Nihon Kohden researcher Takuo Aoyagi in the early 1970s. Pulse oximetry measures blood oxygen saturation (SpO2) non-invasively with an infrared sensor on the fingertip. Before that, the measurement of blood oxygen saturation required arterial blood sampling. Thanks to pulse oximetry, the critical parameter of SpO2 can be measured painlessly, continuously, and in real-time. If you want to find professional and reliable SpO2 sensor suppliers, look no further than APK Technology.
