helmholtz··on Ask HN: What are some of the best books you have read in 2022?
Very interesting recommendation. Is it a slog to get through? Or readable?
helmholtz··on The art of the desk setup (2021)
For sure. I love writing, and it's less screen time, plus cognitively better. I have an armchair for reading research papers etc. But I just clean up afterwards. I think Tablets are an unnecessary environmental cost. I bought a 32" 4k display and optimized my PDF reader with shortcuts for margin notes, highlighting etc. to not need to print paper out. But when I do, I'd rather do a paper print-out than stare at another portal of distraction. Even a Remarkable tablet or something sounds excessive to me.

Why?

Your whole being leads to a design process. Your whole being, the circumstances you grew up in determined what you value. This determines whether you like cozy spaces, or stark sterile spaces, dark or light wood, pops of colours or neutrality. If you grew up with hoarders, perhaps you were always drawn to zen minimalism. And if you nourished that seed, later in life, you wouldn't just be able to leave that need at the door when you started designing something. You'd bring your whole value system to it. You'd look for elimiation. Same with if you like symmetry, or if you like "authenticity" which is maybe just a posh word for transparency of purpose. My favourite example of this is the Windows Phone. They assumed people are digital natives, and don't mind flat rectangles which tell you just the information you need (live tiles) and no more. It started the downfall of skeumorphism and put paid to Apple's old iOS design too, but in effect, it was driven by a value system of an interface being digital-first and not needing to conform to physical reality since people are well-versed with the digital world.

Perhaps designers love to talk too much about this stuff, all of it in hushed worshippy tones which can be off-putting. But there are kernels of truth in it, I think.

Mine looks exactly the same because I clean it. I work paperfree anyway, since I can do engineering on the PC. I ruthlessly move everything out of my visual periphery and in a storage or a cabinet away from my eyeline.

Whether that makes me a deadened robot, or even marginally more effective than the next guy, is of course not entirely clear. It's just a compulsion. But the point is that people who are fastidiously tidy with their workdesks aren't mythical unicorns, but everyday people.

helmholtz··on Meta Learning Backpropagation and Improving It (2020)
That one always cracks me up. Munroe truly is a genius. The 'imaginary friends' one is just as funny.
helmholtz··on I help seniors with technology issues
Video editing, photo editing, connecting a Focusrite to the machine. Connecting a midi keyboard. Connecting a remote printer. Connecting a Bluetooth headset. Getting usable battery life. Installing software that allegedly supports Linux. All this and more are issues I've had with my Linux installations. Yeah I could have used a different distro, and yes many of these u could solve. But it sure was a pain learning it all.
helmholtz··on How to use a watch as a compass
Isn't this incorrect? If it's summer, south of the Tropic of Cancer, the stick should be North of the line. It's the Tropic of Cancer where the sun is overhead, not at the equator. Or did I understand basic astrophysics wrong.

Similarly, in the winters, I'd imagine North of the Tropic of Capricorn would play the role of the Tropic of Cancer.

helmholtz··on Intel and the $1.5T chip industry meltdown
As always, it is a question of degree. A young adult in the 70s had plenty of time to reflect and live outside. The technology of the preceding 50 years has not made this more accessible. If anything, the slot-machine nature of our computing reduces the likelihood of it.
helmholtz··on Google Pixel 7 and Pixel 7 Pro
Hedonistic Adaptation. People love the photos of themselves from the 90s, 80s, 70s and every previous decade before that. You're definitely on the bleeding edge of that adaptation. For most people, phones from 5 years ago are already extremely goood.
helmholtz··on Adversarial Collaboration
And? GPs response was way more combative than the explicit pause. The guy took pains to highlight "assuming a good faith discussion". Clearly, it's a question that IS on the table. It's driven by wanting to understand further the other side's thought process. I'd love to have a question like that. It would make me pause and ponder and reflect. Always a good thing. Not "immediately end the discussion". Crikey.
helmholtz··on 58 bytes of CSS to look great nearly everywhere
That website really grinds my gears. He's the equivalent of an HN influencer I guess, because I seem to come across him every three days. Like the Stratecherry guy. And it's so naff. It's clearly designed to look like that on purpose and it's kind of a thumbing-your-nose at your audience thing. "My words are so important that you can get fucked if you want max-width". It REALLY annoys me way more than it should. After all, it's just another dude on the internet.
helmholtz··on Packing a backpack (2014)
If you're a long distance hiker, Matt Shafter's video [1] is very useful. The sleeping bag, instead of going first thing in, kind of spreads _around_ the other heavier objects, which we try to keep close to the lower back / belly button level.

Having done my own share of hikes, though, I will say that going ultralight right from the beginning has been a gift that has kept on giving. Seeing people carry heavy tents and stainless steel cooking gear and ridiculously heavy sleeping bags makes me quake in my shoes. I just couldn't do it.

And then lastly, I really, really, cannot say enough good things about ease of access. I have shoulder pockets for compass/sunglasses. A bottom pocket in my backpack (Palante) for snacks and trash storage. Side pockets for water that I can reach without taking the pack off, and they're deep enough to not have the bottles fall out. A fanny pack for small items like chapstick, sanitiser etc. And finally _deep_ pockets in my shorts for my phone. NOT having to take my pack off makes me happy over and over and over again.

helmholtz··on My First BillG Review (2006)
Brilliant. I had to look up how to solve it, but highly recommend others spend some time on it.
helmholtz··on JSON Crack – Visualize JSON data into graphs
High-brow humour is not HN's strong suit it would appear :)
helmholtz··on Color has been disappearing from the world
Key word being some. If everything is emphasized than nothing is. Growing up in India, I'd day good riddance to shouty colors and permanent visual overstimulation. Grey is calmn. Neutrals are calmn. Fuck colors.
helmholtz··on Slow Travel
Could you give more context to why that is so? Couldn't it be adjusted the way something like income tax is?
helmholtz··on Productivity porn
That's not my experience. I need to be making progress to be sane. Achieving something small everyday makes me have confidence in life and a sense of control. This is crucial to keep existential dread at bay. I have a calendar where I track life events (good and bad). It's wonderful to look back and remember that, tlin the last two years, even though I feel like I haven't changed, actually a lot has.
helmholtz··on Diablo Immortal player spends $100k, cant find anyone suitable to matchmake with
Succinctly, that is why we have the society we do. Great meta commentary.
helmholtz··on Cognitive decline linked to ultraprocessed food, study finds
Why are you seeking absolute definitions where none exist? If you have to ask, its probably bad for you. Edges of the grocery store, avoid the aisles, ingredients-not-meals, things not in packaging.... Rules of thumbs abound. Next, a bit of ultra processed stuff is obviously not going to kill you. Some soy sauce, or the ocassional frozen pizza is obviously OK. And its obvious that your example is needlessly contrived. No, its not processing.

This whole thread reads like pedantry for the sake of it.

helmholtz··on Cognitive decline linked to ultraprocessed food, study finds
Flat leafed parsley, Parmesan, and mix this all into farfalle and its a Gordon Ramsay approved recipe.
helmholtz··on Cognitive decline linked to ultraprocessed food, study finds
This seems like unnecessary nitpicking. What would you say are examples of ultraprocessed food that's not full of salt, sugar and fat?
helmholtz··on A lazy way to solve differential equations
Hahaha, my first thought as I clicked the comments was "I wonder if Chris already has this in DifferentialEquations.jl" and here we are.
helmholtz··on The rise of air conditioning (2018)
"Apparently not your case"

My friend, I lived most of my life in India. Trust me. I know everything there is to know about heat. I KNOW the engineers who're in this field. I see them every year at the same damn conference, where they talk the same damn talk all the time.

Hypothetically, sure, one can do both. Improve efficiency AND reduce. But please, tell me where we've done that? CPUs? Electricity usage? CO2 emissions? Nowhere.

helmholtz··on The rise of air conditioning (2018)
It's useful in warm and humid climates. In warm and dry climates, a swamp cooler will beat the pants off of an airconditioner in damn near every metric you can think of.

So, sure, in the swamps of Florida, we should be OK with using the AC. But in the dry heat of Texas? Or southern California? Why doesn't America do even the simple things right? In city planning, in cooling, in HOA's dictating lawn upkeep and on and on and on.

helmholtz··on The rise of air conditioning (2018)
And stepwells, and latticework false walls, and high ceilings, and ventilators at the top of the house, and having a false-basement thing in houses where it's a bit cooler in the afternoons, and siestas and walking slowly from place to place, and loose-fitting linen clothing, and lemonade. But no. My shitty white plastic Carrier A/C is all I care about. Housing in the US is depressingly shite.
helmholtz··on Logitech MX Products are incompatible with AirPods
It is intrinsically better though. Wired sound infinitely nicer sounding, and with much lower latency. Will we ever have a day when wireless will be sufficiently low latency?
helmholtz··on Goodbye, shitty Car extends Vehicle object-orientation tutorial (2011)
Yep, me too. I guess most programmers dont know what modelica is or does.
helmholtz··on Chasing utopian energy: How I wasted 20 years of my life
"Plenty of supply" and "peak oil" are not mutually exclusive
helmholtz··on SpaceX said to fire employees involved in letter rebuking Elon Musk
Username checks out I guess. This is an extremely low-effort comment. It seems that you would _prefer_ to live in a society where job security is so fragile that a well-meaning letter can get you fired?
helmholtz··on Coinbase lays off around 1,100 employees
What the fuck? So one should actively go out and seek more of it? To me, BECAUSE things are uncertain, there's even more value in things that can be made certain. Then, we at least have the hope of being free to devote our limited, anxiety-riddled, conflict-avoidant, procrastinating brains on the parts that matter. I don't want to have to worry about things like health insurance or the wham-baam-thank-you-ma'am nature of US Capitalist idiocracy.
