irjustin··on High Diesel Prices Bankrupted 16 Trucking Companies in Just 30 Days
> I don't expect "trucking" to fail

Trucking is a fundamental need so once competition thins out prices will naturally rise and eventually the cost of fuel will be pushed to the customer.

Honestly I'm not sure why we started this war. It really feels like our president taking notes on Russia and saying you know what....

irjustin··on Scientists observe Einstein's gravity in the quantum world
Ah missed this - 2 days later, sorry.

I'm over my head with your statement, but my guess is - Yes that's the point. Either you do 2 way or you accept 1 way clock-sync collusions.

My argument is it's not "We don't know speed of light in 1 direction". Also, there's another common youtube video that says "we've never measured teh speed of light!".

Those statements are just for click bait, shock value. It's not rooted in the science.

irjustin··on Show HN: What if the speed of light was 5 km/h?
From the light's perspective: "what is this.... time you speak of?"
irjustin··on Scientists observe Einstein's gravity in the quantum world
Criticism: It's not literally impossible.

I hate this one because it's true Einstein said we cannot measure the speed of light in one direction that is independent of the clocks' synchronization technique being used to measure.

And yet, somehow we changed that to "we don't know the speed of light in one direction!!!" Which is bogus - can you imagine if speed of light was different if you were pointing east vs west? In space, what is even a direction vs another?

Did you even read the wiki you linked? We've done one-way speeds, it's down below.

irjustin··on Prompting Is Dead in 6 Months. Andrew Ng, Stanford [video]
Copy and paste the transcript. A bit of effort but it's well worth it for these kinds of things.
irjustin··on Black hole singularity is a surface not a point
Is this a variation of a naked black hole/singularity? If so, PBS space time has one on it[0].

Upshot is if you spin it fast enough... acgoiawef.awef?

irjustin··on Coding expertise is going to collapse from AI reliance
Bun? Of sorts? Hard port to Rust in a week and then merged in? No way they reason about that entire thing.

A business won't die just because an LLM is the only thing that can reason about a particular code base. At least, not like if a company's own engineers couldn't reason about their own code 2 years ago.

I recognize you don't agree with it - our world is changing.

irjustin··on Coding expertise is going to collapse from AI reliance
Yes and that's okay.

Very few people know how to read assembly, instruction sets, binary or even transistor combos. All those layers have been "left behind" to become specializations.

In many ways coding is always about abstracting and LLMs can be a form of "higher level coding".

There's lots of problems with this argument, but it's what's happening and we'll be okay. We've always been.

irjustin··on Why aren't smart people happier? (2022)
Yes but very possible. I also did it during the latest once the latest election was decided.

Removed all news sites but also stopped looking at facebook, news on youtube, and the biggest one was reddit.

Reddit really affected me. It was so easy to read -> become angry -> engage.

I choose to be less informed to save my mental health, I know I'm way happier.

irjustin··on Hacker wipes Romania's land registry database
> Except for certain industries where the government has a direct interest (banking, healthcare, real estate)

That's still a massive dependance on "ID" for SS...? Blockbuster tho.. phew it's been a while.

irjustin··on Hacker wipes Romania's land registry database
> SSNs are not a "national ID"

That's not what they are, but that's what they've defacto become. I hate it.

irjustin··on Pebble Mega Update – July 2026
Yeah I agree if it was 10 yrs then I would say no need to charge, but apparently it's 2 yrs? In that time frame you could totally recharge it.

I agree losing the charger is actually pretty likely but THAT'S ON ME. For a $75 product, I don't want to consider it a consumable.

So 100% agreed, +$10 add terminals and a special charger.

irjustin··on Job queues are deceptively tricky
I remember learning about CSV parsing and how it's conceptually simple, yet beyond the simple , and quotes: the corner cases bloat your parser 10-15x.
irjustin··on Mawlynnong, India, transformed by tourism, bans visitors on Sundays
I know statements like this mean well, but man it's so frustrating. It's the same thing as telling a person with depression to "just be happy".

If it were so simple this would've been solved nation wide by Modi's 2014 address.

Where does this education come from? Leaders, but leaders are product of their social environment. To create this change means to go against the norm meaning someone or a few have to break the trend. Then that belief has to take hold in others and THEN the real test begins. It has to be generational, the new generation, by yes, education, needs it to be truth as opposed to a new way. The old guard must die.

Only then will you "solve all social issues by education". Don't even get me started on scale. It works on a village or small country, but more? or a 2nd issue?

irjustin··on Parental device use and the adolescent-caregiver attachment bond
I largely agree this is a weak study, but it also feels like no matter how you run this study it's going to be flawed.

Parent-child interactions, relationships, feelings are probably the hardest thing to quantify at any scale.

In the end, it's really, "Pay more attention to your kids", which is a pretty good universal message to put across.

irjustin··on Building a real-time AI tutor for 5-year-olds
Without malice, I bring up GPT-Live-1. How does this compare and/or make you consider things?

I've been very impressed with response speed, intonation, and naturalness to the voice. I argue it might be too natural with some of it's pausing and saying "ummm" and other filler words to the point it might be disingenuous but that's neither here nor there.

irjustin··on I think I have LLM burnout
Giving my "otherside", because the pressure to output more at work is real, but at the same time, out side of work, I love this. I'm able to do way more projects than ever before because a barrier to entry was always the amount of research+time required to start up a pet project.

My latest is, I'm really into fizzy/soda water and wanted my own continuous carbonator. My entire build from water source to tap with an ESP32 controlled pump, pressure, water level, cooling fans.

There were so many areas I made mistakes in my shopping cart and it found it - like Home Brewer likes 8mm lines but water filter systems like 9.5mm. Really optimized the versions from a simple on/off pump w/ float switch to effectively a full on PLC system. So many iterations gained by chatting with "someone more experienced". Once I get the parts I can build and have the software side running in less than an hour.

It doesn't make money, but man I really enjoy it.

irjustin··on Learning to code is still worthwhile
For now, I can imagine a not too distant future where this is largely untrue.

LLMs are an abstraction just like machine code -> assembly -> C/JVM -> some lang -> LLMs?

At some point you stopped needing to understand the layer down because the layer you were on became so good. Yes there are always corner cases, but for the vast majority of developers/engineers out there, staying at your layer was enough to make a career out of it once your layer hit a certain maturity.

irjustin··on Fable turned reMarkable into Tom Riddle's diary from Harry Potter
What did you expect?

For me the video is basically what I expected. Maybe a cool/spookier "full page" reveal but that doesn't really work with the token speed well.

irjustin··on Why jet engines aren't made in China
> All the money and talent in the world...

One nitpick, all the money in the world would be able to achieve the goal by simply giving rides away for free.

Overall, I agree that any industry that is extremely optimized requiring ultra high precision+knowledge in multiple verticals makes the barrier to entry beyond difficult. It just requires too much up front cash.

irjustin··on Global review confirms mRNA vaccines are safe, effective and full of promise 
The parent is talking about pre-covid, no one wanted pay the upfront cost to bring mRNA out of the lab.
irjustin··on The Doorman's Fallacy in action
I won't fall for it. Been down that road and I'm not going back.
irjustin··on The Doorman's Fallacy in action
I am on the other end of the spectrum.

I enjoy QR ordering. I dislike talking to people. Upselling me is not a thing. I can take as long as I want. I don't have to flag/bother someone. No one screws it up except me. I see exactly what's on my bill.

irjustin··on Blogging can just be stating the obvious
This is obvious? Am I stating the obvious?

It's why I follow Scott Manly or PBS Space Time specifically. There's lots of the same content on other channels/mediums. But I like them specifically, so why not?

Continuing to state the obvious, this is why you specifically should write if you have opinions you'd like to get out.

irjustin··on Ubisoft co-founder Claude Guillemot has died in a plane crash
This is true for pretty much everyone in every skill. But that's an empty statement.

A huge danger for motorcycle riders is young/new car drivers who fall into this exact local minimum.

irjustin··on How we run Firecracker VMs inside EC2 and start browsers in less than 1s
Personally I consider it fair game in "price wars".

Dynamic pricing designed to extract every penny out. Then why shouldn't I be allowed to monitor your pricing changes?

irjustin··on SpaceX to buy Cursor for $60B
Unsure if you're serious, but if you are, they wouldn't buy with cash, at least not the vast majority of it.
irjustin··on Launch HN: Drafted (YC P26) – Models for residential architecture
Oooofff I want there to be some truth to this statement.

The SIMs ran my life for a while and today if there was a "build this plan into a real house" as a lead gen...

My gut says the crossover/cross-sale is just too hard and niche, but if it works, it sounds like one of those genius ideas.

irjustin··on OpenAI mulls slashing prices as it competes with Anthropic for users
We run monthly. It seems like every few months there's a reason to swap in/out of a particular vendor. Specifically I use all 3 pro then either chat or claude will have a 5x max depending if they're the good thing to be using during that those 3 months.
