I've got one of those crazy-wide screens that I usually use at 5120x1440 and it's great. However, since I work remote, I often want to share my screen with someone on a typical 16:9 screen and the options of "tab", "window" or "entire screen" aren't particularly useful because I need to switch between windows a lot as part of the sharing session: terminal, IDE, browser, back to the terminal, etc.

I'd like to be able share either (a) a portion of the screen (half?) or (b) change my resolution temporarily to something like 2650x1440 and just share the whole screen.

The problem is that as far as I can tell, (a) isn't an option, and while I can (b) change my resolution to something 16:9, it renders wide across the screen turning effectively every pixel is a wide rectangle. It's... hard to look at.

I'm using Arch with GNOME+Wayland. Is there some way for me to do either of the above?

EDIT: I found a nifty little Python script that does exactly what I was hoping for in (b) above. Apparently this is a built-in feature for Wayland, but most browsers don't implement it (yet?)

In the very first episode of Star Trek: the original series, we see a white Captain reporting to his black Admiral boss, a black woman on the bridge just a couple years after Jim Crow was abolished, wearing a short skirt (a symbol of feminist liberation at the time), a Japanese helmsman on the bridge only 20 years after the internment camps, a Russian crewmate on the bridge during the Cold War [edit: actually did not appear until Season 2 but the point stands], and the foundation of the modern concept of queercoding.

In the very first episode of Star Trek: The Next Generation, we see male crossdressing crew members, a female officer on the bridge in charge of security, a literal ship's counselor stationed at all times on the bridge, a single mom raising her teenage son on her own while juggling a full career in medicine, a blind mechanic whose "disability" is shown to be a strength, and an angry, all-powerful godlike being who is revealed to be simply a petulant child masquerading as a deity.

In the very first episode of Star Trek: Deep Space 9, we see a black man gain a powerful command position, respect the hell out of the customs of a religion he didn't understand, show respect and equal treatment to members of three other alien races he didn't understand, appoint a female guerilla fighter who defeated imperialist fascists to a position of authority within his administration and defer to her judgement in areas of her expertise, accept his friend's gender change, and tell his son he loves him.

Star Trek has always been woke. You just grew up to be a bad person.

Can someone check my math on this? It feels... wrong:

After cycling a little over 8000km on our e-bike, our battery died. Rather inconvenient, but thankfully we had a variety of cycle shops nearby and one of them was able to find us a replacement.

Ours is a Bicicapace Just Long a fantastic cargo bike with a Shimano motor and battery. The battery that we originally purchased with the bike was no longer available, so the replacement battery is a newer model. It is however a legit Shimano battery rather than a cheap knockoff prone to exploding.

The total cost, just for the battery was £600. Interestingly, this is roughly what I paid for my entire road bike about six years ago.

The steep price tag got me thinking though: if all I can expect to get out of this battery is 8000km, what is the "mileage" of my e-bike? Math is not my strong suit, but the number I arrived at is not inspiring:

If we take the cost of travelling 8000km and ignore the marginal cost of electricity for the sake of my sanity, the cost per kilometre is:

£600 ÷ 8000km  = £0.075/km

That feels... high. My kid's school is almost 5 kilometres from our home, so every day we take her to school, we're effectively paying £0.75 for the return trip and again to go pick her up, so £1.50. That's £7.50/week (not including the weekends which are busier).

Given this, I wondered what it'd cost to do this with a car — only counting the fuel mind you — and the result wasn't inspiring.

The average milage in the UK for a diesel car is 43MPG. I opted for diesel for this exercise 'cause that's what it seems like everyone is driving here. Converting this to metric, you get:

1gal → 4.5461L
43mi → 69.2018km

69.2018km ÷ 4.5461L = 15.22 km/L

With this value, we can calculate how many litres of diesel one might use to travel 8000km:

8000km ÷ 15.22km/L = 525.62L

Finally, with the price of diesel currently here in Cambridge hovering at around £1.569/l, that means that the price to pay for the diesel alone for the same distance I travelled on that £600 battery was only a couple hundred bucks more:

1.569 * 525.62 = £824.70

That's... not inspiring. It's really hard to convince people that cycling is cheaper when the costs of regular use are so high compared to the ridiculously low cost of fossil fuels. Sure, the electricity cost is negligible, and there are many many other costs associated with cars, but having just bit the bullet on £600 battery after such a short time, let me tell you, that taste is bitter.

Tim Hickson is one of my favourite creators on Nebula and YouTube. I think he's hit the nail on the head here.

• Another video he made recently that I thought was excellent

Evelyn Woods (aka eevee) has posted some venerable takes over the years (she also wrote my personal favourite rant of all time: "PHP: A Fractal of Bad Design"), but this one, where she connects industry's generic idea of "content" to what she refers to as a "Whatever machine" is really quite excellent.

I think a lot of people out there are fundamentally misunderstanding the reasoning behind the big tech companies (and their investors) pushing AI into everything. We want to believe that it's just tech bros trying to woo idiot investor cash into their systems — and it is that, a little bit anyway — but the big players: Microsoft, Google, Meta, and even Visa know exactly what they're doing and it's not good news for the rest of us.

Anyway, I wrote this a few days ago to break down the problem as I see it. I'm hoping it proves helpful.

It seems like a great initiative, and I'd be happy to help out, but I don't have a venue myself.

I've been a Steam customer for a very long time, having spent a few thousand dollars over the years with them. Like many of you, I've got a (small?) group of games that I bought and barely-if-ever played, and I'm cool with that. As they say, piracy is a service problem, and Steam is just... easy.

That was until I bought my Deck. Suddenly, I had two devices on which I could play my games: my proper gaming rig upstairs and my Deck plugged into the TV downstairs.

I also however, have a kid that likes video games, so sometimes I let her play a few games on the TV... and that's where everything breaks down. If she's playing Lego Marvel on the Deck, my copy of Dyson Sphere Program flakes out upstairs with a warning that "someone else is playing a game, so this game will have to shut off" or some nonsense like that.

I'm suddenly face to face with the fact that I don't actually own my games and those few thousand dollars weren't spent on what I expected. It's... enraging to put it gently.

I can appreciate that there would be an attempt to prevent me from playing the same game on two devices (though I think that's bullshit too), but to prevent me from playing two different games on two different machines when both are legally purchased running on my own hardware is not ok.
