Project Euler VS Dor

• Problem-Solving Skills
  Project Euler offers a range of problems that can help enhance your mathematical and algorithmic problem-solving abilities.
• Programming Practice
  It provides an excellent platform to practice and improve your programming skills across multiple languages.
• Mathematical Insight
  Many problems require a deep understanding of mathematical concepts, thus helping users to gain and apply advanced mathematical knowledge.
• Community
  Project Euler has a vibrant community where you can discuss problems and solutions with like-minded individuals.
• Free Access
  All the problems and resources on Project Euler are freely accessible, making it an affordable way to learn.
• Self-Paced Learning
  Users can progress at their own pace, making it suitable for learners of all levels.

Possible disadvantages

• Steep Learning Curve
  The problems can become very challenging quickly, which might be discouraging for beginners.
• Limited Step-by-Step Guidance
  There is little to no step-by-step guidance or hints available, which might hinder the learning process for some users.
• Focus on Mathematics
  The heavy focus on mathematical problems may not appeal to those primarily interested in practical programming tasks.
• Lack of Immediate Feedback
  The platform does not offer immediate feedback on code submissions, which might slow down the learning process.
• No Built-in IDE
  Users need to use their own development environments, which might be inconvenient for some, especially beginners.

• Accurate Foot Traffic Counting
  Dor uses thermal sensors and machine learning algorithms to provide precise and reliable foot traffic data, helping businesses make informed decisions based on accurate visitor analytics.
• Easy Installation and Setup
  Dor's sensors are wireless and easy to install, reducing setup time and ensuring a smooth onboarding process without the need for complex wiring or specialized technical skills.
• Cloud-Based Data Access
  Dor offers cloud-based data access, allowing users to view and analyze foot traffic data in real-time from anywhere, making it convenient for multi-location businesses to centralize their data management.
• Battery-Powered Sensors
  The sensors are battery-operated with long-lasting power, providing flexibility in sensor placement without being restricted by proximity to power outlets.

Possible disadvantages

• Potential for Data Privacy Concerns
  As a cloud-based system, there may be concerns regarding the handling and security of sensitive data, especially for businesses that comply with strict data protection regulations.
• Limited Indoor Analytics
  Dor primarily focuses on foot traffic counting, and while it's effective for this purpose, it may not offer advanced indoor analytics or behavioral insights compared to more comprehensive retail analytics solutions.
• Dependence on Internet Connectivity
  As an internet-dependent system, any interruption in connectivity might hinder real-time data access and updates, potentially affecting decision-making based on live data.
• Ongoing Costs
  While the hardware installation is straightforward, businesses may incur ongoing subscription fees for continued access to cloud-based services and analytics features.

• Anyone have experience with traffic counters / people counters?

  I'm looking at Dor (getdor.com). They're appealing because I don't have to run power or low voltage, AND they integrate with square.... And they include batteries with the subscription.... But of course... it's yet another subscription.... Source: about 4 years ago
