Same here, I suspect the majority of people with average to small hands could never really one hand phones (with a good enough screen size) in the first place so it makes less difference to them.

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

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 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.

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.

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 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.

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.

I had the same issue and found floss picks worked well, but after a while the pins just became too worn. Thankfully my new phone has wireless charging.

> I get that they're not the same device, but is it really 2.1x the device that the 13 is?

It looks like you're using an average lifetime of 9 years for the 2.1x factor. I rarely see phones past 6 though and that's approximately how long they receive updates for.

I've also never seen a used iPhone that cheap where I am. Here a new 15 max is $1450 and a used 13 max is $1000.

Using a 6 year life:

$1000 / (6-2) = $250

$1450 / 6 = $242

So if you use a phone to the 6 year point, you are paying less for a better device, and without any unknown damage or wear. Migrating less often to a new device is also a small time saver. Even if you go to 9 years, the new iPhone is only 1.13x more.

I thought the biggest issue wasn't with the models themselves, but how Zillow decided to apply and act on them, which is why it didn't work in practice.

So on average their predictions may have been pretty good, but since each transaction also depends on the other party to accept their offer, and whether they get outbid, most of their predictions where the offer actually goes through would be on the tail end of where they slightly overestimated the price.

This tweet from the article summed it up nicely

> Zillow made the same mistake that every new quant trader makes early on: Mistaking an adversarial environment for a random one. https://twitter.com/0xdoug/status/1456032851477028870

I was lucky to make and learn from that mistake pretty quickly with some algorithmic trading on much smaller amounts. With housing transactions being much larger and slower, you wouldn't learn this lesson until it was too late. Models never perform as well in practice as they do in theory, and you need to remember to account for both known unknowns and unknown unknowns.

> I too can never remember jq syntax when I need to. I usually just end up writing a Python script

Same here! That's why for small things I made pyxargs [1] to use python in the shell. In another thread I also just learned of pyp [2] which I haven't tried yet but looks like it's even better for this use case.

Thank you! My original use case was for running ffmpeg in directories with encodings that broke xargs, and later added the py/pyev flags which basically swapped subprocess.run() with exec()/print(eval()).

I didn't really highlight it in the documentation but it can also run commands in parallel as multiple windows in a multiplexer so it's easier to checkup on their progress or interact with them.

I have never heard of pyp before, looks neat!

I made something similar myself, pyxargs [1], which doesn't have all the magic of pyp, but although being geared towards more xargs like usage, it also functions somewhat similarly.

For example, although not as clean as the magic variables x, l or line, you can use '{}'

  ls | pyp 'x[:3]'  ==  ls | pyxargs --pyev "'{}'[:3]"

Overall the syntax of pyp looks much better, and the --explain feature is nice since pyp seems to do a little more for you under the hood (the closest pyxargs equivalent being --dry-run). I think I'll start using pyp myself when not running commands over multiple directories of files or in parallel.

If it's even still possible to install/activate them. Whenever any of them became available on Steam I would rebuy them there just for the convenience.

Similar to bandwhich, I recently created a snap of my own bandwidth monitor, picosnitch [1]. However I was only able to get it working with classic confinement due to there being no snap interfaces for fanotify or BPF kfuncs. Unfortunately this meant it couldn't be published on the store.

I already packaged it for nearly every distro, but unfortunately most don't have dash [2] in their repos so the user needs to install it separately, and I was hoping that snap would be an easier solution for that.
