maxk42··on Ask HN: What's your favorite software testing framework and why?
Do you imagine QA catches everything?
maxk42··on Venture Predation
Funny to see nobody's mentioned Cloudflare yet. They're not making any money: This is presumably their exact plan: Offer CDN services and other web infrastructure services at a loss for a prolonged period of time until the competition is destroyed, then jack up rates and eat the market.
maxk42··on Heart attack deaths drop over past two decades
You've got it a bit mixed up Nicotine has not been definitely linked to cancer. Cigarette smoking has, however. But nicotine has been linked to heart disease and related cardiovascular illnesses.
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
The government owns the majority of the unimproved land in the US. The government does not own the majority of the warehouses in the US. For instance, in my state, the majority of the land (40 million+ acres) is owned by the government. Another 20 million acres not owned by the government is unimproved. The majority of both those quantities is not merely unimproved but not being utilized for anything at all - not even livestock. (It's desert - very expensive to produce most livestock out here.) And it's not even in the top five states in terms of area. In some places not far from here, land can be purchased privately for $5 / acre. I think you underestimate just how much unused land there is in the USA.
maxk42··on Tell HN: The “Y” logo in the top-left corner has been upgraded to SVG
In this case the extra request to the server (and associated response) to check if the file has been modified is several times larger than the minified size of the SVG inline. It's literally faster and fewer requests to inline it.
maxk42··on Place mushrooms in sunlight to get your vitamin D (2012)
Vitamin D is a precursor to a wide range of essential human hormones including both estrogen and testosterone.
maxk42··on Place mushrooms in sunlight to get your vitamin D (2012)
Mushrooms produce vitamin D2. Animals produce vitamin D3 endogenously. There's no medical literature in aware of showing that vitamin D2 is equally useful to the human body.

Why on Earth didn't you just inline it?
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
The sands here are black, my friend.
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
Warehouses are not uniform. If you were to pick any of the vast millions of acres of free land in the mountain west, you could simply pick a suitable flat area near existing power transmission lines and get to work. If you were trying to develop that capacity on warehouse rooftops you'll run into a variety of problems from: (1) Some warehouses do not have rooftops that lend themselves to power generation. (e.g. they include smokestacks, antennae, vents, and other features that make some of the roof unusable) (2) It is inherently more labor-intensive (and therefore expensive) to haul solar panels onto a rooftop and install them around existing infrastructure than to put them into place in a suitably-prepared empty spot on the ground. (3) Warehouses are not situated in spots that are optimally chosen for sunlight exposure and therefore may not be very productive for solar power. Many will exist in the shadows of mountains, buildings, or trees. Others exist in places where natural forces such as ice, hail, and rapid temperature swings will shorten the expected lifetimes of solar panels. (4) The inherent costs associated (labor, logistics, materials) with setting up 10,000 small solar plants and connecting them to the grid will naturally exceed the inherent costs of setting several large purpose-built locations and connecting them to the grid.
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
Were you planning to build solar panels for the wildlife?
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
Somewhere south of the environment effects of building tens of thousands of warehouses.
maxk42··on What if we covered every warehouse in the mountain West with solar panels?
It would be a lot more expensive to put them on warehouses than the millions of acres of unused land nearby. But the mountain west also has ice and hail and solar panels tend not to live up to their expected lifetimes out here.
maxk42··on Reduced cancer mortality with daily Vitamin D intake
What do you use for tracking your blood vitamin D levels?
maxk42··on Shopify will be smaller by about 20% and Flexport will buy Shopify Logistics
WooCommerce was purchased by Automattic and since then it's been very difficult to implement without paying for SaaS components. Still possible, but no longer straightforward.
maxk42··on Parrondo's Paradox
Further down the article there's a simpler example: https://en.wikipedia.org/wiki/Parrondo%27s_paradox#A_simplif...
maxk42··on Monolith: The Recommendation System Behind TikTok
Following the link to the cuckoo hasing algorithm on Wikipedia, I don't quite understand what it's doing. I looked up another couple articles but still find myself confused. Does anyone have a link to a resource with an easy-to-follow writeup of how cuckoo hashing works?
maxk42··on Mass layoffs and absentee bosses create a morale crisis at Meta
If the Metaverse was succh a great idea Secondlife would be much more successful.
maxk42··on Ask HN: Have any notable companies failed because of poor code?
Knight Capital comes to mind.
maxk42··on New Orleans teenagers found a new proof of the Pythagorean Theorem
On my phone at a restaurant right now so I'm not looking it up but this was previously in a published paper in 2009. Not to rain on their parade: this is a great start for a couple of math prodigies, but they didn't quite discover a new proof.
maxk42··on My kids and I just played D&D with ChatGPT4 as the DM
NPCs in AAA video games are about to get so cool.
maxk42··on Managers exploit loyal workers over less committed colleagues
It's not "unpaid work" if you're classified as an exempt employee, which is never explicitly addressed in the article. That's why you get a certain salary regardless of sick leave, holidays, etc - you are being paid to apply your professional skill to a task, not conduct menial labor for a certain number of hours. I would never work unpaid overtime when I was working as a retail clerk. That's why they had a time card system which I had to punch in and punch out of. If a customer kept me late by even 15 minutes, I'd be compensated for all of that time. Now later in my career I'm an exempt professional, and I don't mind crunching when it's crunch time. That's part of why my salary is so much higher now: I understand that I have a job to execute at any cost. If a deadline is in danger of being missed I will put in the extra hours necessary to achieve success regardless of being asked to or not. That's why managers award me crucial projects and that's the kind of employee I would lean on when I have a crucial project of my own to manage. That's also the first employee to be put up for promotion and the last one to be expendable during hard times. This isn't the least bit surprising.
maxk42··on Half of Black High School Students in the Bay Area Can Barely Read
Educational opportunities are not a zero-sum game.
maxk42··on Call yourself titles
I noticed you said "was" and not "am". I think that's the point others here are making. You put in the work and did what it took to become a runner. However, the author of the article is advocating calling yourself a runner once you've gone on one or two runs. That's not the same. The point of my first sentence being that you don't call yourself a runner when you're not running regularly and perhaps others shouldn't either.
maxk42··on Starbucks CEO will work a shift at the company’s cafes once a month
I think it would be better if he stuck to one. That way employees might over time become comfortable enough to voice their concerns to him. A one-time visit would feel more like an inspection than anything else and everyone would be on their best behavior.
maxk42··on Starbucks CEO will work a shift at the company’s cafes once a month
I would believe that's the case if Narasimhan were working a full shift, but he's only working half a shift once a month. At that point why bother? What are you going to learn in 4 hours a month where all the employees are on their best behavior and the store is made immaculate prior to your arrival?

Thank you. Just passed 7 of them. Will see if it helps.

Curious... I've been using LinkedIn for a job search and am unfamiliar with the questions to which you refer. How can I find and pass this test?
maxk42··on Instead of paying adults more, states let companies hire kids for labor shortage
These lawmakers are apparently proposing to reduce the age of labor to 14. That's exactly how old I was when I began working in CA. If anything I'm wondering why 14-year-olds can't work in those states already.
maxk42··on Lisp-powered laptop with a battery life measured in years
Hi there! Neat project! Can you give us a rundown of some of its features? Which processor are you using? Do you intend to sell these or are you only creating a prototype?
