mplanchard··on CEOs Who Think AI Replaces Their Employees Are Just Bad CEOs
Could you quote that? I don’t see it.
mplanchard··on What it feels like to work with Mythos
The WASM thing makes sense. Do you need unknown-unknown? Seems like support exists for emscripten and wasi: https://github.com/mlua-rs/mlua/issues/366

It just seems like a lot of hassle to write a lua interpreter, although it would be nice to see a high quality one in Rust :)

Hematita was promising, but looks abandoned.

mplanchard··on CEOs who think AI replaces their employees are just bad CEOs
This is a shallow dismissal of GP’s point. The point is more, “we aren’t sure it won’t work because it has never been tried,” which is much less of a straw man to argue with.
mplanchard··on CEOs Who Think AI Replaces Their Employees Are Just Bad CEOs
This seems hard to tease out from the fact that a) the majority of companies do not survive, b) the large, large majority of companies that do survive do not wind up being large or innovative, and c) there are far fewer coops than regular companies. If you assume equal chance of success between them, you’d still see vanishingly small numbers of large, innovative coops, because a small percentage of a small number is small.

What’s wrong with mlua?
mplanchard··on Federal judge blocks H1B visa $100K fee
I really think y’all are underestimating the reality of living in rural Alaska. I wouldn’t take a job there unless I had literally no other livable options.
mplanchard··on Federal judge blocks H1B visa $100K fee
Do you want to move to Alaska, and rural Alaska at that (although even “cities” in Alaska are rural by most standards)? You get to be thousands of miles from your existing community, you won’t have a grocery store nearby, there may even be no way to get into or out of your village except by plane. Maybe in the winter you’ll be totally snowed in for weeks at a time.

You could offer me twice what I make as a software engineer and I wouldn’t take the job.

mplanchard··on 1worldflag: A blue dot on a transparent background
Yeah I don’t disagree, but I think the difficulty is kind of the point in the GP’s post: it would take an unprecedented era of peace for us to collectively agree that the idea of “surrender” is an anachronism ready to be reclaimed for a better purpose.
mplanchard··on 1worldflag: A blue dot on a transparent background
from the post you replied to:

> and the fact we embraced it as a flag of unity over a flag of surrender should say all there is to say about us getting over our differences

mplanchard··on Dopamine Fracking
I think this is a “yes, and” kind of situation. Yes, a lot of parents suck, and yes, we should try to improve that situation, but also yes, we absolutely should punish megacorporations for making parents’ jobs harder by targeting children with their proven-to-be-harmful products.

Like, parents shouldn’t give cigarettes to their children, BUT ALSO it is both illegal and immoral for tobacco companies to target children.

mplanchard··on Ripping a DVD, a federal crime in 1999, requires $22 and free software in 2026
$22 is an expensive sandwich, to be fair! Certainly not unheard of, but probably more expensive than your average sandwich even in a big city.
mplanchard··on The circus freaks of open source
Haha yeah, in this case. But that’s hardly the norm, and it would be a weird thing to assume any time someone starts hurling racial epithets or whatever. It makes sense to me to ban that type of “hot” discourse from a community, because it doesn’t contribute in any way to productive conversations, even if it is sometimes caused by something the poster doesn’t control, like schizophrenia.
mplanchard··on New U.S. college grads now have higher unemployment than the average worker
Why? The average life expectancy is ~76 for men, ~81 for women. You’re saying you shouldn’t be able to pull a full pension unless you have devoted ~half of your entire life to a company?

45 years doesn’t even seem feasible if you want to retire at 65, since most people graduate college at around 22. Add in a masters or a doctorate and 45 years of work would bring you into your 70s.

mplanchard··on New U.S. college grads now have higher unemployment than the average worker
Yeah I ran some numbers in another comment on this post, and I was a bit surprised to see that NYC’s units per capita number is about 42%, 5% fewer than my much smaller (but also plagued by lack of housing and lack of affordability) city at 47%. They’re planning to add 200k units over the next ten years, which is a start, but even if we assume no population growth, that still only gets them an additional 2.3% more units per capita. They’re also trying to spur more private development.
mplanchard··on New U.S. college grads now have higher unemployment than the average worker
Does that hold up per capita? Units per area isn’t super meaningful when comparing housing costs without a sense for the size of the population competing for them.

Where I live has ~21k units for ~45k residents (47%), and a median home price of $440k or so. NYC has about 3.6 M housing units for ~8.5 M people (42%), and a median home price of $870k. For NYC to make up that 5% they would need around 425k housing units.

Obviously these numbers can’t tell the whole story, but it does seem like the supply is fundamentally more constrained in NYC than here, and here is already pretty tight, with very low vacancy rates, high rental prices, and expensive homes.

Anyway NYC plans to build 200k units over the coming decade, increasing the supply in order to reduce the cost. Of course that’s not the only item in the plan to reduce costs, but it’s a major component.

mplanchard··on The circus freaks of open source
Form and content are not perfectly separable, especially when we are talking to people, where the purpose of language is often to create a lossy expression of our thoughts. Content expressed with a slur for an ethnic group, for example, says something about a person’s underlying thoughts that the use of a more neutral term does not.

My point is mostly that cherry picking a city-specific assault scenario and acting like it’s super common is no different from me saying “better than living in bumfuck louisiana where cletus will sexually assault you in the back of his pickup truck.”

The murder thing is also an error of faulty generalization. As a counter example, Opelousas, Louisiana, a nothing town with barely more people than yours, has a murder rate of 39/100k, higher than your example of Baltimore, and much higher than New York (3.92/100k).

mplanchard··on Do we need billionaires?
My favorite way of conceptualizing the difference between being a millionaire and a billionaire is relative purchasing power. If I have $100k in the bank, so not even a millionaire, a billionaire has 10k times more than me. If Let’s say I imagine making a normal purchase for someone with six figures in assets, like a car, and let’s say the car costs $20k. Imagine what that feels like. It’s a big purchase, right? Probably will use a loan for it, pay it off for a while. For someone with $1 billion (10k difference), the car is the equivalent of something that costs me $2. They don’t even have to think about it, it affects their total monetary position not at all. If on the other hand I’m a millionaire, and I’m imagining buying the same car, it’s a bit easier: equivalent to me with $100k buying something that costs $2000. Still though, a $20k purchase for a millionaire is just a $20 purchase for a billionaire.

I know net worth != purchasing power, but they are likely correlated enough for the examples to be broadly accurate.

The quote defending the billionaires also reminds me of this piece from a recent Harper’s about the march in support of the ultra-rich: https://harpers.org/archive/2026/05/billionaire-blues-thomas...

mplanchard··on Changing how we develop Ladybird
It certainly didn’t kill Manhattan, but it did kill or at least seriously maim lots of small towns. We lost a lot of local culture in the switch to everything being available online. I’m not sure we’re better off.

Nobody ever gets assaulted or murdered in the country, eh?
mplanchard··on 1-Click GitHub Token Stealing via a VSCode Bug
Emacs with vim bindings (evil mode) is also pretty great, and about as stable as it gets. I’ve been all-in for I think 6 or 7 years now. I just the other day installed a little package for tyographic quotes that hadn’t been updated in 16 years (!!), and it worked great.

Depending on what third party packages you use, you may sometimes get breakage there, but if you start out with a kit like doom emacs, you’ll be largely insulated from that.

There’s also always newer stuff like zed, which looks pretty great and is very snappy in my limited testing.

mplanchard··on Gmail thinks I'm stupid, so I left
I use and like proton for my custom domain. Haven’t used fast mail though so I can’t compare. I like that messages to other proton users are automatically encrypted.
mplanchard··on Only 17% of all 64-bit Integers are products of two 32-bit integers
I don’t think so, because that only gets you up to 2x2^32, which is nowhere near halfway to 2^64
mplanchard··on To have a moral stance on AI is to be an outcast, and it sucks
I think you’re objectively right, and I try to maintain that perspective. But, I think of this karma not necessarily in a negative way, just kind of like the chickens coming home to roost for us all.

I’m (and presumably many of us are) feeling the destabilizing effects of my industry now in a similar way to how many other professions have felt its effects before. Given our industry’s impact on society, it’s important that we feel this effect directly, so that we can do a better job of empathizing with the industries we’re “disrupting.” Whether or not I have personally participated in those aspects of the industry, I share inescapably in its overall karma, which is why it’s important to not just opt out of the parts of it I feel are immoral, but try to push for it to be better where I can.

mplanchard··on AI job grief: A psychological crisis hitting tech workers
It’s different, because in our field we’re often learning or doing new things, as opposed to merely rehashing the exact same thing we’ve done before.

I find it very difficult to learn a new thing by reading it, vs by doing it.

And indeed, most mathematicians, who do get paid to do math, work a lot with pencil and paper. If math is secondary to your job, you likely will not, but if it’s your primary job, you likely spend a lot of time working ideas out in the more primitive fashion.

whoops “mono” obviously, but past the edit window now
mplanchard··on AI job grief: A psychological crisis hitting tech workers
It feels to me more like the way doing math on paper does.
mplanchard··on Shantell Sans (2023)
I was also really hoping for a mino version. I have used comic-sans-inspired monospaced fonts for some time for coding, because I think they are extremely readable. This font is so beautiful, I’d really love to see it in my terminal
mplanchard··on Shantell Sans (2023)
I am not dyslexic, but the roboto example also highlighted a very stark difference in readability for me! Especially after having gotten used to shantell sans reading up to that point, the roboto felt nigh-unreadable.
mplanchard··on To have a moral stance on AI is to be an outcast, and it sucks
It does feel a bit karmic, doesn’t it? I’ve never worked in a part of tech that was explicitly doing this, but I still feel as though all the current anxiety and uncertainty I myself am currently going through is in some way “earned” by my participation in this industry.
