Unfortunately almost all VR games in my experience feel more like tech demos than full games. Even Half Life Alyx felt like a demo mechanically to me, but I had a good amount of VR experience before I played it. The only couple of VR-native games I've played that feel like full games are VTOL VR, a flight sim designed from the ground up for VR including buttons to press and switches to flip, and Pavlov, a shooter. Otherwise, many of the best games are VR-additional that can be played flat as well, like Elite: Dangerous, DCS, or the racing games.

Also Skyrim VR was breathtaking, especially with mods to improve the scenery and clunky menus.

> Why would anyone want to give themselves motion sickness for a VR game?

VR is fun despite some discomfort, much like other experiences like roller coasters. I'd volunteer to participate in such a study because I'd like to do more VR than my body can naturally tolerate.

> Will people who condition themselves too well to tolerate VR entertainment also break their vestibular system

Definitely worth studying! From the few I've heard adapt, no, it doesn't make them significantly more likely to have balance problems.

I really enjoy that roller coaster feeling both in real life, and in VR games like Jet Island and Windlands.

I'm pretty interested in this and would like to participate in a study as well if given the opportunity. I think one of the potential causes and solutions is it being a self-fulfilling prophecy that may be overcome with self-efficacy as described here [1] for seasickness. My only evidence is that I never knew motion sickness was a possibility when I first tried VR, and my friends with the worst motion sickness were worried about it before they even tried VR, even if they never got seasick or carsick.

From the article and other comments, they also mention figure skating which I never thought of before, and I play ice hockey which is likely similar enough. For reference I've been playing VR since 2016 and never once experienced motion sickness, from any style of game/locomotion.

I realize this is a dumb question, but what's a good way to do this between an iPhone and a MacBook? Airdrop is disabled (by policy), iCloud storage is full (because I'm lazy), and I use syncthing on every other device, but I haven't found a client I can use on my work iPhone.

If they're on the same network, cross platform, open source airdrop alternative https://github.com/localsend/localsend

I use python more often than tools like awk, which I often forget the syntax of, so I made pyxargs to quickly run python code in the shell for small tasks like this

  sp current | pyxr -0 -g "(Artist)\s+(.+)\n(Title)\s+(.+)" -p "{3} by {1}"

Are you looking for something like a call graph?

There's pyan3 [1] which although doesn't support python 3.7+, I've still had luck with v1.0.4 which works better for me than its most recent version with python 3.11, but there can be some weird issues though depending on your code style.

A quick search also turned up crabviz [2] which has support for more languages than just python.

There's another article I was reading last week about this

https://skyandtelescope.org/astronomy-news/asteroid-will-cov...

It's really stunning how much information can be gathered from such an event.

All this knowledge merely from our single planet by tiny variations of measurements in finely calibrated instruments as if you were able to map out the city of Paris confined to the observations from a single window.

elesiuta · 2 years ago

Great article, I've always been impressed by this too. It's neat that it sounds like even amateurs with nothing but a regular DSLR can contribute to this as well.

> By precisely timing the duration of the occultation from many sites simultaneously, they can refine their knowledge of the size and shape of the asteroid.

> Betelgeuse is the 10th brightest star in our skies (+0.5 magnitude), so observers need only modest equipment to participate.

> the easiest way to capture the event is to use a simple DSLR camera on a tripod ... video frames must have a short (few-millisecond) exposure time ... Millisecond accuracy timing is crucial ... [an app] for timestamping occultation observations is called Occult Flash Tag (Android) or AstroFlashTimer (iPhone)

Someone remarked upthread about Artem's very excellent Trail post, which you can sum up as "attackers can create conditions where eBPF events might not be generated, or where eBPF probes won't be able to see the requisite data". In a pure logging monitoring situation, those problems aren't that big of a deal (the things you'd have to do to force those conditions will be noisier than the events you'd be trying to generate, and, more importantly, the things you'd do instead of eBPF to do that kind of monitoring have their own gruesome limitations).

But as soon as you add a "drop" response to events, you've switched from a monitoring tool to a reference monitor; at that point, this stuff has to work.

elesiuta · 2 years ago

Yep, and from my experience too (made a tool that monitors network traffic with eBPF [1]) in addition to those issues there is also a sizable latency hit.

I use it with ssh and password auth disabled, is there a reason not to? Might be overkill but the host is in my home so physical access if I ever get locked out is not an issue.

elesiuta · 2 years ago

I think this is still reasonable, attackers may have a database of leaked keys (e.g. if you ever accidentally commited to GitHub, or ever ran a malicious script which uploaded it), which they then try on random servers.

To expand on this, don't use it because a good approach is to disable password authentication on SSH and use keys instead.

If for some reason you still needed password auth enabled I'd be inclined to still use f2b.

elesiuta · 2 years ago

I require both key and password to login, and have fail2ban rate limit password attempts.

This gives sufficient notice to fix things if a key were to become compromised.
