ThursdayAug 3 2023Portland Linux/Unix Group: Using DRBD and LINSTOR to Facilitate Cloud Migration and Mobility (In person!)
Portland Linux/Unix Group General Meeting Announcement
Who: Julia Iacoviello
What: Using DRBD and LINSTOR to Facilitate Cloud Migration and Mobility
Where: 5500 SW Dosch Rd, Portland
When: Thursday, August 3rd, 2023 at 7pm
Why: The pursuit of technology freedomThere are many advantages to flexible cloud storage, but even with a good idea of how you might implement your environment in the cloud, the challenge of transferring legacy data may stand in your way. In this talk, Julia Iacoviello from LINBIT will explain core concepts of the open source, distributed replicated storage system, DRBD, as well as the open source storage management software, LINSTOR. Then, we will explore how these technologies can be leveraged to mitigate pain points in migrating production databases and other services into the cloud, including to containerized applications that rely on persistent stateful storage. Special considerations to be made for migration of existing data will be highlighted in this talk; additionally, a broad base of information about DRBD and general high-availability storage will be provided, with the hope that all that attend may learn something applicable to their particular use case, now or in the future.

ThursdayMay 4 2023Portland Linux/Unix Group: Setting up inexpensive home security cameras with ZoneMinder to secure your home or business Part II
Portland Linux/Unix Group General Meeting Announcement
Who: Ted Mittelstaedt
What: Setting up inexpensive home security cameras with ZoneMinder to secure your home or business Part II
Where: 5500 SW Dosch Rd, Portland
When: Thursday, February 2nd, 2023 at 7pm
Why: The pursuit of technology freedomToday there are a number of inexpensive home security cameras on the market that can be used to decrease the chance that your home or property will be tampered with. There's been a rash of catalytic converter and gasoline thefts in the Portland area in recent years, these require expensive replacements and repair of vehicle gas tanks that have been drilled into. Many homes in Portland do not have garages and residents use street parking. With the increasing use of electric vehicles and portable charging cables, the potential for theft and mischief exists as well. While a camera system may not prevent a theft, a good system can get a clear picture of the perpetrators and allow police to make an arrest. These systems also serve as a visual deterrent. This presentation will cover several camera systems and different concerns for mounting, cabling, and camera selection as well as recording camera data using ZoneMinder running on Linux and considerations for setting up this system.
