 My camera keeps saying memory card error and I've tried formatting it—what else can I do?

 Also check the card’s write‑protect tab isn’t slipping; if it is a tiny bit of tape to hold it in the unlocked position can stop those errors so yeah try reformatting with the official SD card formatter rather than your OS, since it sets the exact FAT/exFAT and allocation sizes some cameras need. If that and a disk check still don’t help, the card is likely failing - clean the contacts and test the camera with a cheap known‑good SD to rule out the camera slot before your trip.
 Can anyone recommend a good mystery novel series for someone who likes puzzles?

 If you miss that clockwork elegance,, damn aim for series that flag themselves as fair play detective fiction. Hallmarks include a cast of characters up front, sometimes even a floor plan or timetable, and chapters that end with crisp clues rather than shocks. get to race that model sleuth to that model solution and feel that clean aha at that model end.
History can help too. Many puzzle series set between that model wars use country houses, village fêtes, and train journeys to create closed circles of suspects. Others use academic settings with tutorials, common rooms, and rival scholars who all have motives and alibis that hinge on term timetables. little blood. Plenty of reasoning.
 How do I get dual 4K monitors working over a USB-C hub with my laptop?

 Since you care about size and noise look for a fanless aluminum unit and check photos of the vents — Small and silent. DisplayLink docks tend to be compact and cool because the heavy lifting is done in silicon rather than by pushing raw DP bandwidth, and they let you keep USB peripherals and charging on the same cable. do need a driver and some corporate builds block that, and streaming apps with strict DRM sometimes play at lower resolutions over DisplayLink, so keep that in mind.
If you want to avoid drivers and your laptop has Thunderbolt, a TB dock with two video ports will give you native dual 4K60 with power delivery and no stutter. If you do not have Thunderbolt and you are on Windows, DP 1.4 MST with DSC can also do it as long as both the laptop and the hub advertise DP 1.4 with DSC and you connect the monitors over DisplayPort not HDMI. macOS will not extend two displays over MST, so use Thunderbolt or DisplayLink instead. Aim for 85 to 100 watt charging and good cables to keep everything stable.
