I’d expect that the ergo costs of using a laptop at all (short key travel, screen down from eye level) would swamp the additional cost of having the keyboard off center. After all, you can just crane your neck down and sideways instead of just down :).
Seriously, anyone using a laptop full time for work (who cares about ergo) should invest in an external keyboard and monitor.

FWIW, I’ve been using a 15” MBP as my primary dev/work machine for over a decade and I’ve just become used to it. Tried external monitor, keyboard a few times, but it just doesn’t work for me anymore. I mostly run in high res mode, as opposed to the scaled default mode and it works well. This is also why the 13” laptops are not an option for me, am eagerly waiting for the 16” MBP fingers crossed.
It sounds like you're advocating for a desktop system. I usually dock my laptop, but I do like the flexibility of detaching and sitting on the couch. When I'm using my laptop, as a laptop, I like to feel comfortable. To me numpads on laptops have negative value.
Since darktable introduced the scene referred workflow I would argue it's an extremely steep learning curve for anyone coming from display referred software (Lightroom, Capture One etc).
Scene referred is very much a cine-thing and I know of no other still image software that uses it. dt v3.6 made scene referred default.
Aurélien has been one of the driving forces behind the switch to scene referred and his hour long explanations of the new modules can be found on his YouTube channel[1]. Boris has a YouTube channel[2] which is quite the opposite. You watch him edit in silence and you will pick up the craft.
RawTherapee has a more traditional, display referred, approach. If you want local adjustments (which you will want), you need to use nightlies until 5.9 is released.
For anyone caring just enough to wonder what scene referred and display referred are talking about…
scene referred does its filtering and mapping work on the pixel values in a linear space, presumably linear to "photons observed" but I could be wrong there.
display referred does its filtering and mapping on pixel values which have already been through a nonlinear function to make them appropriate for display.
The scene referred people say they don't tend make silly skin tones and avoid "rat piss" sunsets as well as reducing artifacts like halos around blurs. (I presume that means the blurs are something like Gaussian blurs performing linear operations on the nonlinear data.)
> scene referred does its filtering and mapping work on the pixel values in a linear space, presumably linear to "photons observed" but I could be wrong there.
You are correct. If you see Y light in real life, and that corresponds to a pixel value of 1000, 2Y light should correspond to 2000.
> display referred does its filtering and mapping on pixel values which have already been through a nonlinear function to make them appropriate for display.
The nonlinear function is usually 0 brightness to 100% brightness of the media (for instance, pure white on a printed piece of paper or pure white on a display). Scene referred photos technically have no bound (there is clipping, but you can just expose less and increase the exposure in editing to effectively get the same thing)
Of note is that you have to change a scene referred color space into display referred color space anyways...
I have to admit I still don’t get Filmic. I have a basic grasp of it but I am much more comfortable with shadow and highlight adjustments. I have watched pretty much all tutorials I could find but I am struggling big time. I have no idea how other people feel about it but I am starting to wonder if the scene refereed workflow is more an intellectual exercise and less a practical tool.
Filmic mimics the nonlinear dynamic range response on film medium to push the contrast and dramatic look present on the shot.
It also highlights how old film struggles when compared to much more capable CMOS we have today.
I use filmic rather frequently to get the look / emotion response for a shot, however it's not always suitable. Sometimes the lighting is not favorable for it, sometimes the shot I have at hand is not well suited for that because of other reasons.
Shadow, highlights, exposure, etc. are corrective tools while Filmic tends to be an artistic one.
None of what you said makes any sense. For people like me, here is an explanation of scene referred workflow
"The scene-referred workflow places an emphasis on performing image processing in the linear scene-referred part of the pixelpipe. This helps to reduce artifacts and color shifts that can result from processing non-linear pixel values and, by decoupling the image processing from the characteristics of a specific display, it makes it easier to adapt your work in the future to new display media, such as high dynamic range displays."
gist is whether you do your color grading in the camera's original color space (scene referred) or after transforming to display color space (display referred)
> you do your color grading in the camera's original color space
you do your color grading in linear color space (or something that roughly maps to linear color space) is what that actually means. Linear meaning, the exposure of a pixel is supposed to be proportional to the data number, and the exposure is theoretically infinite (since you can have anywhere between 0 and infinite light). For display color space (for photography this is more in line with "print media color space") there is a maximum brightness and minimum brightness, and you have all the numbers to map brightnesses between the two.
The math is a lot cleaner with linear color spaces.
I'm considering the Fairphone as well, but could someone give me a reasonable idea of what to expect with running de-googled vs googled? Unfortunately I still need access to Gmail and Drive from my phone on occasion. Is that still available when de-Googled?
I'd love to have a full Android VM running on a de-Googled phone where I could sandbox all of the Google stuff.
I've run Android Degoogled for many years. Gmail can be accessed via K-9 Mail or another mail client via IMAP. Google Drive can be accessed via a browser such as Kiwi or Firefox.
I just use the Arc GTK theme and use the kvantum Qt theme’s Arc preset. Makes both look pretty much the same. Qogir is another one that’s kind of cross-desktop.
If it's where your passwords and addons live, switching takes effort. Besides, what is the big advantage of Firefox? Chrome has 65% of the worldwide market share. Firefox does not even have 4 [1]. About half of the stuff I build will literally only ever run in Chrome anyway.
OK, you're one of those noble devs working hard to further entrench the Blink/WebKit monopoly situation. I'm sure its practical right now, but try not to be too short sighted. Sorry for the bitterness, but this infuriates me.
Note: the Chrome-only stuff I mentioned runs in a sandbox environment and will not make any difference to the global market. Public projects will work just fine in FF.
But of all the things I am actively fighting for, like decreasing the emission of greenhouse gases, preserving nature and the furthering of various struggling causes that will truly make a difference, I just can't be bothered to take on this fight as well.
Good for you that you can afford to be furious about something like browser market share. For me that's nowhere near the top of my list. Maybe it will move up some day, but at this time I don't feel the need to raise a banner for it.
A friend of mine living in an apartment complex with parking facilities at basement level recently told me that firefighters having inspected the area had come to the conclusion that they will make no attempts to go down and put out a fire if there are EVs parked. There will be fire until there is nothing more to burn, house still standing or not.
Seeing a car battery burn kind of makes me understand why.
> That's just a bad fire department. There are procedures to put out lithium-ion fires that aren't just "let it burn".
That's what they're supposed to do, though, according to Tesla[1]. The firefighters are there to pour water on the fire to cool it down and wait for the battery to burn and release its energy. This is what Tesla's manuals[1] say:
> If the high voltage battery becomes involved in fire or is bent, twisted, damaged, or breached in any way, or if you suspect that the battery is heating, use large amounts of water to cool the battery. DO NOT extinguish fire with a small amount of water. Always establish or request an additional water supply.
> Battery fires can take up to 24 hours to fully extinguish. Consider allowing the vehicle to burn while protecting exposures.
EV battery fires and their risk to firefighers are a national problem[2].
Also, you're expecting a lot from what are often volunteers who have little to no funding. I lived in a place where over $20 million was spent on police salaries each year, but firefighters and EMTs were all volunteers.
I'm one of those volunteer firefighters (Vacaville district). There's no way we would just walk away from a vehicle fire. If it means spraying water on it for hours, fine, then that's what we'll do. If there's no hydrant we'll have 2000-gallon water tenders lined up. On a big wildland fire it's not unusual for the pumpers to be working for hours.
You really underestimate how much firefighters love to use the equipment "for realz". I don't know anyone who doesn't dream of running into a (concrete) parking garage to put out a vehicle fire, EV or not.
Also, nobody (at least in my district) is allowed anywhere near a vehicle accident without bunker gear. If we had to rotate new pairs of firefighters in every 30m when the SCBAs run out, so be it. The department has a lot of tanks. We also have ventilation equipment on all the engines and squad units.
Also also: We're the rural team. The city departments (with their million dollar fire trucks) are even more hard core. "Make no attempt to put out EV fire" is just nonsense.
It can also be extremely dangerous to stay in a closed space i.e. underground parking if you don't have a way to turn off the fire. Most people don't die of fire in fires, they die of less than a minute of breathing in toxic fumes. To tell a volunteer to risk his life to watch a fire burn he can't turn off is a very privileged position to be in.
Firefighters tend to have respirators when they fight fires. It's not like things other than EVs don't release copious amounts of toxic fumes when they burn. ICEs are really not much better in that regard.
The difference is not the toxicity of the fumes, it’s the duration of the fire. A respirator will not fully protect you from a seven hour underground fire.
In an EV fire, you have an initial fire that burns hot and releases lots of fumes (a large part from all the other crap in the car combusting), and then you have a very long period where you have to dump water on the battery to keep the internal oxidation under control by cooling it. The later part is much less dangerous for the fire fighters.
This actually reinforces my point. The first part releases “lots of fumes” into a poorly ventilated underground space, which then requires firefighters to remain for “a very long period.” Your claim that the later part is less dangerous assumes that fumes have dissipated.
> That's what they're supposed to do, though, according to Tesla[1]. The firefighters are there to pour water on the fire to cool it down and wait for the battery to burn and release its energy. This is what Tesla's manuals[1] say:
No that's not what they say. They say to keep it cool to prevent it from burning. You're misinterpreting those instructions.
> besides keep water flowing over the outside of the battery pack while the inside self-oxidizes
But that is doing something other than just letting it burn. That's containing the damage, rather than letting the fire spread to everything around it.
They are different situations, but I'd argue they're different in the opposite way. For a car by itself outside, letting it burn would be fine. But in an enclosed parking garage, it's rather important to keep the fire from spreading to the rest of the garage.
Yes, but the problem with Li-Ion fire in a confined environment is that it generates a lot of toxic gas (doable but you need equipment for that), a lot of hydrogen which will react with everything near by, and the risk of explosion (in the sense of rapid fire expansion with a thermal run-away of most cells) is higher.
My guess is that the floor was poorly ventilated with complex access, rendering the access to the fire unnecessarily hazardous.
I'm not sure if that would do anything much to help; it might just trap the heat in. I think the standard recommendation for Teslas is to just dump water on it so that the extra heat energy can be conducted away and redirected in a relatively harmless way into conversion of water into steam.
>There are procedures to put out lithium-ion fires that aren't just "let it burn".
Can you provide more info on this? I'm very casual on the topic from what I've read is kind of impossible to put them out. Sometimes they have to throw the EV on a water tank and let it sit there for days.
The original poster is incorrect. The correct way to handle lithium ion battery fires is to put tons of water on them to keep them cool. Most of what's burning in lithium ion battery fires is the electrolyte being heated up by shorting batteries. You want to keep them cool so the electrolyte can't burn.
I would say that using lot of liquid CO2 must cool down a lithium fire while also denying it oxygen to continue. That's what a CO2 fire extinguisher does; it's often used to put out small fires in powered electrical installations.
At a car battery scale, especially in a garage, that would require the use of oxygen masks, and evacuating anyone around, because there won't be much to breathe. Also, of course, the fire truck must carry a large amount of liquid or solid CO2 ("dry ice").
Using liquid nitrogen would be even more efficient, but even harder to provide at scale. Liquid nitrogen is cheap, but cryogenic facilities are not.
Lithium by weight is very little of what's in the batteries. It's not Lithium that's burning. Primarily what's burning in lithium ion battery fires is the volatile electrolyte.
Sorry, that's just dumb. A lithium fire is hard to "put out", it's objectively safer than pretty much everything else that burns. It flames and sputters for a few hours, then it's done. Standard procedure for these things is to do nothing but keep it cool and wait. If your fire department can't handle that then I fear deeply for what happens in the next house fire they face.
This is just ludditism. New technology brings out a combination of people afraid of The New and people trying to look smart by pontificating about new New and Scary failure modes.
You really can't fathom why fire departments dislike stuff that can't just be put out, but needs to be kept cool for hours and hours with lot of water?
Cities have fire safety regulations for parking lots and if the parking lot violates it then it can be sealed off until fixed. It doesn't matter what's inside the parking lot unless its legal and say not a nuclear reactor.
ICE vehicles too catch fire all the time, It just seems your firefighting agency is not doing its duty.
I've been thinking that if I have a "power wall" I will want it outside a good distance from the house and in its own cinderblock bunker.
I wonder if it would make sense to install these larger batteries over concrete "basements" or pits and have mechanisms to "drop" them — maybe flood the pit with water.
You will want to do the same for synthetic clothing, cooking oil, and your cooking range & oven.
We already have houses burning down because people left the bacon unattended for a few seconds too long.
House batteries already have thermal management and fire suppression built in. Mount the battery on a brick or metal wall of your house as per the instructions and forget about the doomsday scenarios.
There's an interesting trade-off for people who go the DIY route: LFP batteries are pretty ideal for power storage, for a lot of reasons (safety, durability), but they don't deal well with cold and can't generally be charged if the temperature is below freezing. So, you can have them in the house (in the garage, perhaps) where they'll stay warm enough, or you can have them away from the house where they'll do less damage if something goes horribly wrong, but then you have to figure out how to keep them warm in the winter if freezing temperatures are a thing in your climate.
There is https://www.ddcutil.com/ It has a command line utility and a qt GUI. Unfortunately the GUI is a bit convoluted, because it exposes every option that you can change on the monitor. I once almost bricked my LG monitor, because I accidentally locked the hardware buttons on my monitor, via an undocumented manufacturer specific option.
> Unfortunately the GUI is a bit convoluted, because it exposes every option that you can change
Wow, color me surprised. That doesn't sound like a desktop Linux app at all :)
>I once almost bricked my LG monitor, because I accidentally locked the hardware buttons on my monitor, via an undocumented manufacturer specific option.
Reminds of the good old days of late 90s / early 2000s desktop Linux, when the wrong video timing settings in your XFree86 config could make your CRT monitor (almost literally) explode.
But I'm sure 2022 will be "the year of Linux on the desktop", finally :)
I'd would not like to run "other operating systems", but rather Android/Replicant[1]. The PinePhone is listed as a supported device[2], but I'm finding next to no reports on how it is actually working.
I am not aware of any Replicant build for the PinePhone, otherwise I would have had to try it out and make a video about it [0]. GloDroid [1] has incomplete support for the PinePhone (no support for anything the EG25-G does), that‘s all in terms of Android aside from Anbox or WayDroid that run on top of Linux.
Oh, I'm pretty darn sure I saw it on the supported devices page yesterday. Can't see it now. Hallucinations? :) It's very strange to me that no Android ROM has made it to the PinePhone yet.
