I won’t be going to FOSDEM
Belgian cities full of trigger-happy armed troops, with orders to shoot to kill, and a recent track record of doing so.
In reality, probably a lower risk than regular vehicular traffic, even for those of us with an ample beard and a big backpack. Though surely a far higher risk than the supposed terrorist threat. But that level of security theatre is hardly welcoming to visitors. Since I have the choice, I’m staying away, and withholding the support that might be inferred from my travelling to Brussels for a weekend in the near future.
 That last sentence is a bit disingenuous, insofar as it suggests this is a big change of plan. In reality I hadn’t decided one way or the other. I’ve been doing that of late: I only got around to signing up for ApacheCon in Budapest the day before it started!
