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.

Show HN: Boston Marathon Course Map with T and Rail Stations

The map includes the course route, mile markers, gel stations, T and Rail stations. It could be helpful for a runner planning out the route or a spectator navigating the course.

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.

New comment by jimlawruk in "Ask HN: Any example of successful vibe-coded product?"

jimlawruk — Tue, 30 Dec 2025 18:15:56 +0000

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.

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.

Thanks. Updated link to the home page. Didn't realize my SPA generated Urls don't work. Sigh.

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.

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.

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.

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. :)

> 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.

> 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.

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.
