jimlawruk··on The AirPods Effect
> The number of spoken words uttered by the average person fell by 28% between 2005 and 2019

This effect started well before Airods and even smart phones became ubiquitous. The airpods were released in Dec of 2016. Before Blackberries and Iphones, people on the subway all had daily newspapers in their face. In DC we had a free abridged version called the Express.

jimlawruk··on Grand Theft Oil Futures: Insider traders keep making a killing at our expense
So then the person who uses public information is actually the bigger fool than someone who uses no information whatsoever and just picks a side of the bet. If insiders know that a volcano is going to erupt and offers a 50/50 payout, people who know the historical improbability will bet that is will NOT erupt, thinking it is an easy payout. But there will be some idiots out there that bet that it will erupt based on dumb luck.

Isn't there a 50% chance you are betting on the "insider" side of it?
jimlawruk··on Agentic AI systems violate the implicit assumptions of database design
I work with an Oracle database like this. In the old days, there was a 30 character limit on column names, so you end up with conventions like no vowels. The limit no longer exists today, but the DBA continues to enforce the limit on new columns.

jimlawruk··on James Moylan, engineer behind arrow signaling which side to refuel a car, dies
Our plugin hybrid has both a gas side on the left and electric side on the right. The electric side on the right is helpful in the US to allow parking curbside and charging the vehicle.
jimlawruk··on Ask HN: Any example of successful vibe-coded product?
Here is an web app that tracks the grocery prices of my shopping at Aldi. It is meant to track grocery price inflation over time. It is obviously limited and incomplete since it is just based on my haphazard Aldi shopping. It includes a "basket of goods" total for each quarter, graphs, product pages, etc. It is coded by an LLM (except for maybe the initial commit). I don't write or edit the code, but I do sometimes "look" at the code, and ask for changes based on what code I see, so purists might question it as being 100% vibe coded.

jimlawruk··on Is it a bubble?
If you look at the chart at the bottom comparing Dec 99 to today....

> during the internet bubble of 1998-2000, the p/e ratios were much higher

That is true, the current players are more profitable, but the weight in SPX percentages looks to be much higher today.

jimlawruk··on Egg prices vs. Consumer Price Index since 1980
Thanks. Updated link to the home page. Didn't realize my SPA generated Urls don't work. Sigh.
jimlawruk··on Egg prices vs. Consumer Price Index since 1980
I have been haphazardly tracking my grocery prices at Aldi since 2022. My lowest price was $1.12 per dozen in Nov 2023, my highest was $5.97 in Feb 2025. Last recorded price in September was $2.71.

jimlawruk··on Ask HN: What are some impressive vibe coding projects?
Here is my personal project that tracks my Aldi grocery prices of products over time. My rule for the project is, all code must be done by the Copilot agent within VSCode. I did hand type the Git commits.

If you include local governments, then the education spending percentage gets higher, but still nothing close to healthcare.

This sets up the other quote from the movie: Michael Burry: “I may be early but I’m not wrong”. Investor guy: “It’s the same thing! It's the same thing, Mike!”

From the Big Short: Lawrence Fields: "Actually, no one can see a bubble. That's what makes it a bubble." Michael Burry: "That's dumb, Lawrence. There are always markers."

jimlawruk··on Ultra-processed foods make up more than 60% of us kids' diets
Fiber is also beneficial for the "good" gut bacteria, as it feeds on fiber. Fiber also binds to your LDL "bad" cholesterol in the digestive system and helps to eliminate it.
jimlawruk··on Show HN: Ten years of running every day, visualized
Great job. The website is well done, too. I had a streak of about 400+ days several years ago which I ended the day after a marathon. Today I take off when I am sick or the day after a long race. The morning coffee doesn't taste right unless I run beforehand. :)
jimlawruk··on Some arguments against a land value tax (2024)
> The point is to force landowners to develop their land.

The point is to ensure landowners don't sit on land. If taxes go up on your vacation home that you spend two weeks a year in, you will be incentivized to sell it or rent it out more. Both of which benefits the public at large. Not to mention it is a fairer tax than an income tax or wealth tax.

jimlawruk··on Some arguments against a land value tax (2024)
> land value tax is a regressive tax on middle class homeowner

Not if you make the tax progressive. The first 200K could be tax free, for example. Primary residences pay a lower % of the value than 2nd and 3rd homes. I bet there are a ton empty vacation homes in Vermont. It can be applied gradually not to shock the system.

jimlawruk··on As a developer, my most important tools are a pen and a notebook
I have a notebook that I bring on vacations or weekend trips to jot down occasional bouts of inspiration. A few of those pages contain designs of pet projects that may or may not get implemented later. It can be fun to sit on the beach and map out a potential design even if you never end up implementing it.

jimlawruk··on Catholic Church to Excommunicate Priests for Following New US State Law
So does this law apply to other confidentiality protections like attorney client privilege, or just the confessional seal? If you confess to a lawyer, does the lawyer have to report you?

jimlawruk··on Researchers are studying how to minimize human impact on public lands
This is where locals have an advantage. My friend lives in CO and knows a bunch of fantastic hikes that maybe are not in a NP or that tourists don't know about yet.
jimlawruk··on Exercise before bed is linked with disrupted sleep
Yes, a Garmin. My sleep score and HRV is way off if I run in the evening. It is shocking, actually.
jimlawruk··on Exercise before bed is linked with disrupted sleep
This became more of an issue when I got older. I used to run in the evenings and get away with it. Now in my 40s, I have to run in the morning. If I run at night, I wake up feeling tired and not well rested.
jimlawruk··on When I converted my home from gas to electric my utility bills nearly doubled
Author lives in Northern California. Not the DC area. So was the cost double for just one month? What were the rates? Guessing around $ 0.30 /KHW and $2.25/therm? What was the heat pump HSPF?
jimlawruk··on Alzheimer's biomarkers now visible up to a decade ahead of symptoms
> Catching these clumps early while still in minute quantities can enable effective intervention

I wonder what interventions they mean here. Drugs, lifestyle changes?

jimlawruk··on AI Photo Geolocation
I put in a photo of a small lake near Truckee, CA, several miles from Lake Tahoe, and it reported it was Lake Tahoe. It was wrong, but impressed it was geographically very close.
