samch··on Apple detectives solved mystery of ancient tree and rewrote the history of fruit
Here is a different link covering the same topic without requiring a subscription:

samch··on Doom in MS Paint from Mark Russinovich
“The actual Doom engine (ViZDoom) runs the real shareware DOOM1.WAD — with the BSD-licensed Freedoom WADs covering the episodes shareware doesn't ship — and renders headlessly; every frame is placed on the Windows clipboard and pasted into Paint's canvas as a genuine document edit.”

Pretty impressive

samch··on Crypto in 2026: Oh, This Is the Bad Place
The war on drugs, due to its targeting of specific socioeconomic and racial groups, is probably not the best analogy here.

While I do get your point about the FUD it generated, a better parallel might be the rise (and eventual fall) of the tobacco industry. There was a lot of fraud and deception in the 20th century about the health effects of smoking. There were ads touting that more doctors preferred brand X. The idea was to correlate something genuinely dangerous and lethal with good health.

Crypto and betting markets, to the author’s point, are repeating this pattern again today in terms of personal finances.

samch··on Gaussian Point Splatting
It seems like there are fairly regular posts on HN about splatting, and most appear to be fairly technical or proof-of-concept level. While the outputs look nice, I’m not sure that I could distinguish them from a nice ray-traced scene. What I think I’m missing is the “why?” of splatting. What are the material benefits of this area of research?
samch··on Under Notre Dame, a 'dig of the century' unearths 1,700 years of history
The author should’ve known that we already have an accepted unit for measuring things in terms of a person’s stature:

Obligatory XKCD: https://xkcd.com/974/
samch··on Pomiferous: The most extensive apples (pommes) database
Nice database (got a brief glimpse before it was hugged to death). Personally, I’ve always really liked this apple rating site (no affiliation):

samch··on The smelly baby problem
Agreed - like the sibling comment, we also used cloth diapers with our two kids. They were actually great. The ones we had were basically two-part construction: there was an outer shell with adjustable snaps for appropriate sizing, and an inner liner that absorbed the moisture. Both were easily washable. Like other parents we knew who did this, we added a small hand-held sprayer / bidet wand to one of our toilets and used it to hose off the diaper and liners. We would then toss them in the washing machine. I think these also provided more cushion for the kids’ bottoms and they both ended up sitting and scooting on them pretty fast. Also like the others here, we used disposables on the go / on vacation. Just my two cents, but we loved our cloth diapers.
samch··on Phyphox – Physical Experiments Using a Smartphone
One of my kids has science project due each quarter in school, and this is our go-to app. We’ve measured acceleration in an elevator, sound attenuation of an audio source in a small vacuum chamber, and the Doppler effect. The app makes it easy to capture and export the data points to make graphs. I highly recommend this even just to play around with.
samch··on Microsoft says bug causes Copilot to summarize confidential emails
Copilot is not a model, to my knowledge. When you’re asking about the data that it was trained on, you are most likely referring to an OpenAI or, in some circumstances, an Anthropic model. Customer data is not used for training the models that run Copilot.
samch··on Claude Code: connect to a local model when your quota runs out
I hadn’t thought about using their first-party API offering, but I will look into it.

Personally, I’ve used AWS Bedrock as the fallback when my plan runs out, and that seems to work well in my experience. I believe you can now connect to Azure as well.

samch··on Microsoft 365 now tracks you in real time?
Some of this could be related to laws that necessitate updated location data for emergency calling. Since a common component of Teams is Teams Phone, there can be a compliance gap. I’m sure this isn’t the whole story, but it is likely one facet: https://www.911.gov/issues/legislation-and-policy/kari-s-law...
samch··on NTP at NIST Boulder Has Lost Power
Can anybody speak to the current best practices around running underground power lines? I see these types of articles about above-ground distribution systems from time-to-time, particularly in California. I feel lucky that my area has underground power, but that was installed back in the 1980s. Would it be prohibitively expensive for Boulder’s utility provider to move to underground distribution? I can’t help but think it could be worth the cost to reduce wildfire risk and offer more reliable service.
samch··on Microsoft 365 Copilot's commercial failure
Copilot in Excel is getting some significant updates. It can write Python now that Excel has support for that. There’s also a new “COPILOT()” function in Excel that works pretty well.
samch··on Microsoft 365 Copilot's commercial failure
The same M365 Copilot app is installed for both “free users” and the premium licenses that have access to all of their Graph tenant data. From the sounds of it, you only have the basic Copilot Chat (web grounded) that comes with the E3/E5 license. If you have the full license for M365 Copilot, you’ll see a work/web toggle at the top of your chat screen.
samch··on Electromechanical reshaping offers safer eye surgery
My wife had PRK done on both eyes over a decade ago, and it was great. At the time, she had the choice between LASIK and PRK (I’m not sure that everybody has both options given their particular conditions). After reviewing the long-term prognosis and possible side effects of both, she went with PRK. It’s been a fantastic decision for her, but that just one person’s experience.
samch··on Killing the Mauna Loa observatory over irrefutable evidence of increasing CO2
Maybe they’ve thought about this and measure that too? Maybe they can adjust measurements based on data from multiple sensors?

samch··on Global hack on Microsoft Sharepoint hits U.S., state agencies, researchers say
Yes, as is OneDrive and Teams file sharing. Those, however, are part of SharePoint Online. SPO is distinct from this CVE, which only applies to the standalone SharePoint Server.
samch··on Xfinity using WiFi signals in your house to detect motion
This is what precisely why I willingly pay more to Google for their fiber optic service than AT&T for an equivalent, albeit less expensive, plan: Google readily allows me to use my own equipment. I am voting with my dollars on this one.
samch··on Denmark: Minister for Digitalization wants to phase out Microsoft
So many of the comments are focusing on Office products. Okay, that’s fair. People can talk Calc vs Excel for example, and that’s fair. What I don’t get is how you replicate knowledge worker collaboration without using a major commercial provider like Google Workspace or M365. How do you handle the use cases solved by collaborative document editing, SharePoint / OneDrive, Teams with DLP, document classification, etc. I’m not affiliated with Google or MSFT, just genuinely curious how you replace the broader ecosystem around the core Office products using open-source solutions. Has anybody solved for this?
samch··on Why I no longer have an old-school cert on my HTTPS site
Since you asked, I use Cloudflare for my registrar. I can’t really say if it’s objectively better or worse than anybody else, but they seemed like a good choice when Google was in the process of shutting off their registry service.
samch··on A Letter to the American People
This is precisely what’s happened with the educational system in many U.S. states:

1. Reduce funding and investment in public education.

2. Claim that our educational system is broken and we need to privatize.

3. Fund charter and private schools with vouchers while continuing to defund public schools.

Unfortunately, I have yet to see steps 4 and 5 where we return to well-support education for all.

samch··on macOS Tips and Tricks (2022)
One Windows shortcut that I use habitually is Ctrl + left or right arrow keys and optionally with shift in order to navigate by or select entire words at a time instead of single characters.

I’ve looked into MacOS approaches to achieve the same functionality in the past, but I never seemed to find anything of use. I’m wondering if anybody here would be aware of a solution.

samch··on PAROL6: 3D-printed desktop robotic arm
This is my favorite DIY robot arm at the moment. The parts seem to be fairly high quality, and it has a leader / follower arm option if you build a second one:

samch··on Backblaze Drive Stats for 2024
A company called TechEmpower used to run periodic web framework benchmarks and share out the results using nice dashboard. Not sure why they stopped doing these.

Edit: Adding a shoutout to the iFixIt teardowns that are also quite informative content:

samch··on Markov Keyboard: keyboard layout that changes by Markov frequency (2019)
I’ve backed this product, the Flux Keyboard, on Kickstarter - it allows for the type of dynamic changes that the author is describing in case others are interested:

samch··on Futel
Reminds me of the 2600 back covers. There is something of the phreaking / phracking culture to this.

samch··on Intel Keychains with Computer Chips
Instead of disposing of or recycling sub-standard chips, Intel used to repurpose some into keychains.
samch··on Kudzu, the vine that never ate the South (2015)
As others have said, RoundUp / glyphosate doesn’t always handle these tougher plants. I’ve had good results with Crossbow: https://www.winfieldunited.com/products/herbicides/crossbow/...

Not sure if that is readily available in all regions, though.

samch··on Overbooking – how providers divide up the bandwidth
I realize this is mostly focused on XG-PON, but I’m curious if this is as much of an issue with WDM-PON that’s in use by some providers (Google Fiber is one, I think).
