Sumatra PDF

RodneyEberly

On our website at work, we dynamically generate PDFs. This requires lots of testing on our local pcs. Adobe Reader is good for viewing the pdf, however, it also places a lock on the file, so that nothing else can access it. So if you make changes to the pdf generation code and want to retest, you have to make sure that you have closed that file in Adobe Reader, otherwise, the code generating the PDF will throw an error.

A great alternative to Adobe Reader is Sumatra PDF. http://blog.kowalczyk.info/software/sumatrapdf/index.html
It is a small open-source PDF viewer for Windows. It may not have all the features of Adobe Reader, but it is fast, and best of all it does not lock the file. So you can keep the file open in Sumatra, even when modifying the pdf from another source, and Sumatra will automatically refresh the view with the latest version.

Modern construction and manufacturing sites are no longer just about heavy machinery; they’re digital ecosystems. Tablets, laptops, IoT sensors, and mobile apps are now essential for everything from blueprint access to production monitoring. These tools enable real-time collaboration, safety compliance, and operational efficiency. But when your workforce is spread across remote job sites or large facilities, keeping these systems connected and secure becomes a challenge. Construction Blueprint & Plan Access: Crews use tablets to view updated plans on-site, reducing errors and rework. Safety & Compliance Reporting: Mobile apps allow instant incident reporting and safety checks. Equipment Tracking: IoT sensors monitor heavy machinery usage and maintenance needs. Manufacturing Production Line Monitoring: Tablets and IoT devices track throughput and detect anomalies. Quality Control: Mobile devices capture and share inspection data in real time. Inventory Management: Connected devices streamline material tracking and reduce downtime. These tools keep projects moving, but only if they’re secure, updated, and accessible anywhere. Why Remote Access Is Critical Construction sites and manufacturing plants often operate in remote or rugged environments. Workers need secure, reliable access to company systems, whether they’re in the field, on the shop floor, or traveling between sites. Without proper management, connectivity issues and security gaps can lead to delays, data breaches, and compliance failures.
