    1. Air travel is profoundly bad for the environment but one of the hardest industries to decarbonize. Can green technologies make a difference before it’s too late?

      Picture yourself in an airship pushing into the northern latitudes. From the vantage of a barstool in the center of a luxurious lounge, you look through panoramic windows to see an Arctic vista scroll past. The ride is as smooth as a cruise liner cutting through a mirror sea. Above you is a white canopy, the base of the great bladder of gas keeping you airborne. Down below, a huge oval shadow glides across the pack ice.

      I disembarked from this flight of fancy and came back to reality in an industrial estate on the outskirts of the town of Bedford, a couple hours north of London. For now, the airship of my imagination sat disassembled in front of me — an engine, the top section of a tail fin, a salubrious sample cabin.

      Hybrid Air Vehicles calls it the Airlander: a colossal, state-of-the-art dirigible that was originally conceived as a military surveillance platform for the U.S. Air Force. That idea was scrapped as America de-escalated its operations in Afghanistan, but by then a new application for airships was emerging. Aviation is the most energy-intensive form of transport, and in recent years the industry has come under intense scrutiny for its environmental footprint. Unlike a passenger airplane, a passenger airship — buoyant and slow — doesn’t have to burn much fuel to stay in the air.

      “We’ve completely normalized flying in an aluminum tube at 500 miles an hour, but I think we’ve got some big changes coming,” said Tom Grundy, an aerospace engineer and HAV’s CEO, who was showing me around the research facility.

      Many of the scientific principles behind Grundy’s airship are a throwback to a bygone age, when Goodyears and Zeppelins carried affluent clientele around America and Europe and occasionally between the two. Other aspects are cutting-edge. The cambered twin hulls will be inflated with 1.2 million cubic feet of inert helium, not flammable hydrogen like most of the Airlander’s interwar forebears. The skin, a composite of tenacious, space-age materials, is barely a tenth of an inch thick but so strong that there is no need for any internal skeleton. Grundy handed me a handkerchief-sized off-cut. “You could probably hang an SUV off that,” he said. When it goes into production later this year, it will be the world’s largest commercial airliner: around 300 feet long, nearly the length of a soccer field.

      But arguably its key selling point — the reason HAV resuscitated a mode of aerial transport once thought to have gone down in flames with the Hindenburg — is that it’s green. Even powered by today’s kerosene-based jet fuel, the total emissions per kilometer from its four vectored engines will be 75% less than a conventional narrow-bodied jet covering the same distance. The Airlander of course is much slower. A maximum velocity of under 100mph means that it’s never going to compete directly with jet airliners. “We tend to think of it as sitting between the air and ground markets — a railway carriage for the skies,” Grundy told me.

      “When it enters service, perhaps as soon as 2026, the Airlander will offer premium, multi-day cruises to hard-to-reach places like the Arctic Circle.”

      A 100-seat cabin designed for regional travel has already attracted orders from carriers in Spain and Scotland. The prototype we were sitting in, with a futuristic carbon-fiber profile and wine glasses dangling above a wraparound bar, is the central section of another configuration called the “expedition payload module.” When it enters service, perhaps as soon as 2026, it will offer premium, multi-day cruises to hard-to-reach places like the Arctic Circle. Behind the communal lounge, a central corridor will lead to eight double ensuite bedrooms. “You’ll even be able to open the windows,” Grundy said.

    3. What are the benefits in the here and now of linguistic diversity?

      A lot of people argue that we should try to protect "minority languages" and support "linguistic diversity", but I struggle to understand why having more languages is actually a good thing.

      I would be very interested to hear about concrete benefits in the present to linguistic diversity.

      Lots of random musings I had on this

      A lot of people say things like "it helps you to think differently" which I have not really understood at all (I speak multiple languages, for context, some quite different), but my sample size is really just me in saying that. They also say things like "protect minority culture" which I think is quite harmful. For example my great-grandmother immigrated to an English-speaking country in the west from Africa (she was Indian-African), and she could not speak a word of English which put her at a massive disadvantage, but also gave other family members a lot more power in their relationship because they could all speak English. [Edit: I think there's a gender aspect where women are expected to maintain the traditional language and the burden is not put on men in the same way]. I get the whole assimilation versus integration, but I think there's a very strong case for trying to assimilate (into the dominant group).

      I have yet to see a case arguing why it is better to have more languages (and thus necessarily less mutual comprehension and a more segregated world) rather than a single one (e.g. if everyone spoke English). My issue is not really with high-level philosophy about what would be better in an ideal world, but multilingualism as a practical concern. For example, Tildes does not really seem to 'believe' in multilingualism because it only allows English (which personally I think is better than if we had people arguing backwards and forwards in many different languages, but I am also a native English speaker so that might prejudice my perspective).

      Most of the arguments about this that I see are from (usually) French speakers bemoaning the decline of their language (and it's kind of ironic to see France becoming a flag-bearer for linguistic diversity given that they exterminated a lot of languages to force French upon the world).

      Platform: Android

      What is your calorie counting/meal planning application of choice? Looking for something simple and hyper-focused on calorie counting, and I'm ok with a bit of macro tracking, however that's all I want it to do - no feature creep into other wellness/fitness goals and coaching, etc.

      I'm fine with paying (as long as it's reasonable) for a simple application without a ton of ads that does this one thing really well.

      Suggestions?

    6. Audiobooks and radio dramas in movie-length (45min~3 hours long)

      Yesterday, I really enjoyed listening to the BBC Radio 4 adaptation of Umberto Eco's The Name Of The Rose (https://www.youtube.com/watch?v=EkpLbVtTAuk).

      And today I'm wondering if anyone has any recommendations for similar audio-books which have multiple voice actors.

      All genre is okay but preferably singular works that focus on story over recurring characters (anthology series are okay). Preferably works that are available on YouTube, or otherwise freely downloadable--but this is not a strict requirement.

    7. Are you currently learning a new language? Are there any languages that are on your wishlist to learn?

      I grew up semi-bilingual (English as my native language, Spanish spoken at least once a day at home), and went on to study Spanish as my language of choice in middle and high school. Despite this,...

      I grew up semi-bilingual (English as my native language, Spanish spoken at least once a day at home), and went on to study Spanish as my language of choice in middle and high school. Despite this, I would still like to further my Spanish language skills/knowledge with some self-paced coursework, as the Spanish I grew up hearing in the house was much more colloquial and then the Spanish I studied in school was the "from Spain" Spanish, rather than the Central American Spanish my family spoke. I grew up being better able to understand more than what I could speak or write myself.

      When I moved onto to college, I wanted to try studying a different language, so I chose French (bad idea; I could never really get the hang of it between the spelling challenges and the pronunciation being so different from the written word). I took one semester and passed just enough to get credit for the class but moved onto to German -- which was a little bit easier than French but more difficult than Spanish. Beginner classes in it were easy for me to learn, but I started to struggle when I got to upper-intermediate. Plus, I'm not always great at spelling in English, and French and German are not "speller-friendly" languages haha.

      Now as I approach my midlife, I am thoroughly enjoying my ASL for Beginners course through my local community college. I find it incredibly intuitive whenever I learn new signs ("oh, that makes sense, cool" when I see a new sign). My mother-in-law has known and taught ASL (as well as SEE) for over 20 years so she is very helpful with me practicing and being able to correct any small mistakes I make. I don't know anyone who is Deaf, but have had a few friends growing up who used hearing aids (I don't think they knew ASL).

      So what about you? Are you currently learning a new language? If so, what is it, how do you like it so far, and what led you to want to learn it? If not, are there any languages on your wishlist that you'd like to learn someday?

      For me, I wanted to learn ASL as a way to connect more deeply with my MIL in our relationship, as well as have some level of ability to sign with those who are Deaf/deaf. I also wanted to learn it because I wanted an alternative way to communicate with my spouse if we are at a noisy event/party/etc. without having to shout to be heard.

    8. Is it wise to relapse into an episode before you get treatment?

      I've been writing and rewriting this to make it more formal, but I've decided to screw it because the original was raw and can probably describe my needs better than my rewrites could ever. So apologies if it doesn't fit the tone of Tildes

      As of right now, I am currently not seeing anyone for my mental health. However, I'm in the process of getting help. I already have a consultation form for one and all I have to is figure out if I'm saying too much because one part ended up being like 16 paragraphs long and I don't think mental health professionals like that...

      Anyways, I've been having trouble getting myself to clean. There's a gap between my bed and the wall that I put in case I ever got bedbugs (never got bedbugs in my life) and what ended up happening is various items of clothing would fall into that gap without me knowing. Which led to a whole bunch of carpet beetles suddenly flying in my room a month and a half ago.

      Here's my concern: I did have a period where I found fleas in my room, and after seeing them a few times I went on a cleaning spree. Eventually my dad had to stop me because I was deep cleaning the house every single day, and when I wasn't doing that I was researching about pest control. When I wasn't able to clean I ended up researching too deeply on pest control, which led me to find out about scabies. Which led me to a delusion that I had scabies, then went straight back to my cleaning frenzy again, this time with this newfound fear that I'm infesting my family with scabies if I don't babywipe or vacuum everything.

      Then one day, I started getting psychosomatic hallucinations that matched the symptoms of scabies. At night, I wouldn't be able to sleep because I would feel hundreds of bugs crawling inside my skin every time it got dark, forcing me to sleep with 3 lamps around me to mitigate the sensation. Every time I got out of a hot shower I could feel it too, but not as strongly as at night. And then when I sought out a dermatologist, because there was no way I didn't have scabies if I was going through all these symptoms, it just suddenly... stopped? Which was my biggest indicator that it wasn't scabies, because it would have never stopped if it was scabies.

      It was a... bizarre experience for sure, but an impactful one. Especially now that it's been about a year since it all went down, and I've been having trouble sleeping because my room gets so stuffy. I keep my window open at all times, even when I'm too cold to sleep, just because the air is so musky and makes me feel like I'm on the edge of throwing up. I don't feel hunger in my room, and all I can think of is how there's carpet beetles in those gaps and how I will have to clean them when I get better. Because I don't want to repeat what happened last year. I don't want to clean and have these stupid carpet beetles or whatever else I find in that gap briefly take over my life like those fleas and imaginary scabies did. For the past few years I've been swinging between moments of depressive symptoms, grandiosity, and paranoia one after another and a few months ago is the first time in five years since I stopped having these back-to-back moments and I just... can't have another one again. Not until I get help.

      But it has come to my attention that help might take a long time. If I need therapy, that might take months, if not years, and there's a good chance if I need medication I won't find the perfect one right away. So either I have to wait until months or years of my room rotting more and more or I clean it now. To clean knowing full well that I might relapse into another stupid paranoid episode because it was a trigger before and can be a trigger now.

      I don't know. I don't know what to do. I want to clean but I don't want to trigger what I went through in the past again. I don't want to trigger anything. Any causes to my episodes I keep it in my head and make it a rule to avoid at all cost, but how do I avoid cleaning when it's impacting my physical health not to clean? I know I should get help, get treatment, but I shouldn't do anything funny while I wait for the perfect solution right? When I have the right treatment and coping mechanisms I can tackle my triggers, so best not to clean? If that's a trigger? I hate this. I just want guidance

    9. I guess this whole time I was a small minority - enjoying working in person

      I’m a software engineer. Any time this topic comes up it’s clear I’m the odd one out. Recruiters will tell me “don’t worry, we’re fully remote!” but that’s not what I want to hear. Co-workers that are mandated to return to office go on a quiet rebellion to stay at home (and to be clear, I love that they are displaying the power that laborers have even without a union). But for me the quality of the work is lower when remote. Video calls suck and are emotionally draining. Collaboration is core to doing work for me. Sure I can close tickets just fine from home. But what if I’m there to wrap my head around the entire system and all of the people involved in it?

      A few things I’m aware of that influence my opinion here:

      • I don’t have kids
      • I am comfortable asserting my free time. I take plenty of time off and typically work six hour days, never with any push back from anyone. I can usually get much more done in six hours than is asked of me
      • Programming is my dream job

      Thankfully I am still able to find fully in-person opportunities around me. So this is really just a matter of understanding the rest of the labor market. I don’t need to or want to change anyone’s mind here.

      This is Album of the Week #5 ~ This week's album is Eminem - The Marshall Mathers LP

      Year of Release: 2000
      Genre(s): Hip Hop
      Country: United States
      Length: 72 minutes
      Album.Link

      Excerpt from Pitchfork:

      But the anger and trauma he conjured from his childhood of abuse and bullying felt uncomfortably real in all his performances. On The Marshall Mathers LP, he suits the action to the word and the word to the action. He picks the right tone for the right mood, the horrorcore of “Remember Me?,” the beleaguered artist on “The Way I Am,” the impish malevolence of “Criminal,” or the tortured, regretful, loving, deranged, murderous everything-all-at-once feeling of “Kim.” We don’t really believe it, but we believe Eminem really believes it.

      Discussion points:
      Have you heard this artist/album before? Is this your first time hearing?
      Do you enjoy this genre? Is this an album you would have chosen?
      Does this album remind you of something you've heard before?
      What were the album's strengths or weaknesses?
      Was there a standout track for you?
      How did you hear the album? Where were you? What was your setup?

      --

      Album of the week is currently chosen randomly (via random.org) from the top 5000 albums from a custom all-time RYM chart, with a 4/5 popularity weighting. The chart is recalculated weekly.

      My kids are 17, 15, 14 and 3. The eldest have heard my repertoire over and over again. I speak of my beloved dad favourites such as:

      2 cows are in a field. One turns to the other and says "Moo!", the other cow says "Oi, I was going to say that."

      2 sausages are in a frying pan. One says "Phew, it's hot in here!" And the other says "Oh my God. A talking sausage!"

      Did you hear about the magic tractor? It was going down the road and turned into a field!

      Now that you have finished laughing, I need some fresh stuff. So what hidden gems do you have for me to steal and use to cause more groans?
