This presentation discusses the Digital Visual Interface (DVI). It explains that DVI is a digital display interface that connects a video source like a display controller to a display device. While DVI and VGA connectors look similar, DVI carries digital signals while VGA carries analog. DVI has several versions including DVI-D for digital-only signals, DVI-A for analog-only, and DVI-I for both analog and digital. Key advantages of DVI are higher quality digital signals and no quality degradation over long lengths, while disadvantages include bulkier connectors and lower maximum resolution than newer interfaces.How to Implement HDTVI

Finding a specific car online can be a time-consuming task, especially when checking multiple dealer websites. A few years ago, I faced this exact problem while searching for a particular vehicle in New Zealand. The local classified platform, Trade Me (similar to eBay), wasnt yielding any results, so I expanded my search to second-hand dealer sitesonly to realise that periodically checking each one was going to be tedious. Thats when I noticed something interesting: many of these websites used the same platform to manage their inventories. Recognising this, I reverse-engineered the platforms structure and built an FME workspace that automated the search process for me. By integrating API calls and setting up periodic checks, I received real-time email alerts when matching cars were listed. In this presentation, Ill walk through how I used FME to save hours of manual searching by creating a custom car-finding automation system. While FME cant buy a car for youyetit can certainly help you find the one youre after!Improving Data Integrity: Synchronization between EAM and ArcGIS Utility Netw...

Utilities and water companies play a key role in the creation of clean drinking water. The creation and maintenance of clean drinking water is becoming a critical problem due to pollution and pressure on the environment. A lot of data is necessary to create clean drinking water. For fieldworkers, two types of data are key: Asset data in an asset management system (EAM for example) and Geographic data in a GIS (ArcGIS Utility Network ). Keeping this type of data up to date and in sync is a challenge for many organizations, leading to duplicating data and creating a bulk of extra attributes and data to keep everything in sync. Using FME, it is possible to synchronize Enterprise Asset Management (EAM) data with the ArcGIS Utility Network in real time. Changes (creation, modification, deletion) in ArcGIS Pro are relayed to EAM via FME, and vice versa. This ensures continuous synchronization of both systems without daily bulk updates, minimizes risks, and seamlessly integrates with ArcGIS Utility Network services. This presentation focuses on the use of FME at a Dutch water company, to create a sync between the asset management and GIS.War_And_Cyber_3_Years_Of_Struggle_And_Lessons_For_Global_Security.pdf

Russia is one of the most aggressive nations when it comes to state coordinated cyberattacksand Ukraine has been at the center of their crosshairs for 3 years. This report, provided the State Service of Special Communications and Information Protection of Ukraine contains an incredible amount of cybersecurity insights, showcasing the coordinated aggressive cyberwarfare campaigns of Russia against Ukraine.
It brings to the forefront that understanding your adversary, especially an aggressive nation state, is important for cyber defense. Knowing their motivations, capabilities, and tactics becomes an advantage when allocating resources for maximum impact.
Intelligence shows Russia is on a cyber rampage, leveraging FSB, SVR, and GRU resources to professionally target Ukraines critical infrastructures, military, and international diplomacy support efforts.
The number of total incidents against Ukraine, originating from Russia, has steadily increased from 1350 in 2021 to 4315 in 2024, but the number of actual critical incidents has been managed down from a high of 1048 in 2022 to a mere 59 in 2024showcasing how the rapid detection and response to cyberattacks has been impacted by Ukraines improved cyber resilience.
Even against a much larger adversary, Ukraine is showcasing outstanding cybersecurity, enabled by strong strategies and sound tactics. There are lessons to learn for any enterprise that could potentially be targeted by aggressive nation states.

What can go wrong if you allow each service to access the database directly? In a startup, this seems like a quick and easy solution, but as the system scales, problems appear that no one could have guessed.
In my talk, I'll share Solidgate's experience in transforming its architecture: from the chaos of direct connections to a service-based data access model. I will talk about the transition stages, bottlenecks, and how isolation affected infrastructure support. I will honestly show what worked and what didn't. In short, we will analyze the controversy of this talk.cnc-processing-centers-centateq-p-110-en.pdf

HDTVI Technology Update
- 1. Opticom Technologies Inc. USA Sales: Battle Creek, Michigan: 800-578-1853 www.opticomtech.com Canada: Head Office (Vancouver): 855-569-3240 www.toughestvideocamera.com May 27, 2016 Technology Update HD-TVI Installation Bulletin 1 May 27, 2016 CD102HD-1 HD-TVI is capable of supporting RG59 coaxial cable runs of up to 1600' on RG59 and 700' on CAT5. However the 1600 over coax must be continuous no splices or BNC T-Connectors. HD-TVI WILL work with splices and BNC T-Connectors but the transmission distance will be greatly reduced. The HD-TVI signal strength drops significantly roughly 200~250 feet AFTER a BNC splice (female to female connector) or a BNC T-Connector. The problem for mills and larger installations will be knowing how many T-Connectors and splices exist on an existing cable run and where these connections are located. In some cases it may be easier to pull new cable. InstallationSteps: 1. Replace the existing Analog DVR with an Opticom HD-TVI DVR. The new HD-TVI DVRs are backwards compatible with analog meaning that existing analog cameras can be connected as well. This will allow the installer to replace analog cameras with HD-TVI cameras one at a time rather than having to change all cameras over at once. 2. When installing HD-TVI cameras it is recommended to first install and connect the camera and check at the DVR end to see if there is a signal. In many instances, particularly shorter runs, the HD- TVI cameras will work without installing any other HD-TVI parts (distributors or amplifiers). 3. If there is no video at the DVR then the cable run likely has multiple connections or the length of cable after a connection is more that 200~250 feet. In this case there are two options: A. If the BNC T-connector can be located it can be replaced with a 1 IN / 2 OUT HD-TVI video distributor shown to the right. The CD102HD-1 will eliminate signal loss at the connection point. The unit requires 12VDC power and a UL approved 500mA adaptor is included. A 1 IN / 4 OUT HD-TVI video distributor is also available Part no. CD104HD-1. B. If the number and location of connections are uncertain then a pair of HD-TVI video amplifiers can be installed at each end of the cable run. In many cases this will resolve the signal strength issues. However there will be cable runs that simply have too many connections or there has been too much wear and tear to the cable over time. The CA101HD-1 uses 12VDC power and a UL approved 500mA adaptor is included with each unit. Note that 2 CA101HD-1s are required for each cable run. CA101HD-1

USA Sales: Battle Creek, Michigan: 800-578-1853 www.opticomtech.com Canada: Head Office (Vancouver): 855-569-3240 www.toughestvideocamera.com May 27, 2016 Technology Update HD-TVI Installation Bulletin 1 May 27, 2016 Spot Monitors & Quad Splitters Most BNC T-Connectors are installed to either feed out to a spot (display only) monitor or into a quad splitter that provides a 4 camera display on one monitor. To date there is no quad splitter equivalent that is HD-TVI compatible. Existing quad splitters can be replaced with a 4 channel DVR that has no hard drive installed. (See chart below for Part Number) LCD monitors are not HD-TVI compatible. Where a BNC T-connector is installed to feed out to a display monitor an HD-TVI video converter must be installed at the monitor. Again in most cases the BNC T-Connector will work and will not need to be replaced with a video distributor. Always test the monitor feed after installing the video converter to determine if the signal strength is adequate using the T-Connector. The AD001TVI video converter has 1 HD-TVI input and provides 3 outputs: 1 Composite (BNC), 1 VGA and 1 HDMI. The unit requires 12VDC power and a UL approved 500mA adaptor is included.
