dmckeon··on How to avoid losing items? Holding pens
Also related: if you place anything on top of your car - coffee, wallet, briefcase - putting your keys with it makes it hard to forget & drive off.
dmckeon··on Hydrothermal explosion at Yellowstone National Park
Before a 1959 earthquake, Old Faithful had a very regular cycle time - thus the name. Since then, the name has become less apt.
dmckeon··on How Olympics officials try to catch “motor doping”
> promoting bike brands and riding bikes provided by their sponsors

Therein lies an answer - change the disincentives - instead of banning cheating riders, ban all of the sponsors of those riders for a time. Now the onus is on the sponsors to discourage cheating.

dmckeon··on I found a 55 year old bug in the first Lunar Lander game
> I also remember this lunar lander game running on a couple terminals at the Lawrence Hall of Science in Berkeley, California, also in the mid 1970s.

I recall lunar lander being available on, IIRC, ADM-3 terminals at Lawrence in early 1973, usually surrounded by a cluster of male teens. One "feature" of the kiosk mode for games was that a carefully-timed Ctrl-C would escape kiosk mode, and allow the user to play other games. Happenstance, or catnip for proto-hackers?

dmckeon··on Explosively pumped flux compression generator
I wonder if some miniature chain shot, made with ~2-3mm split shot fishing weights clamped over 20-30cm of monofilament line, all in a smoothbore shell, would work to entangle drone propellors, and perhaps leave the drone in a reusable state.

Have you found and cleaned all the lint filters and exhaust air passages? A shop vac and/or an electric leaf blower may serve to improve throughput.

dmckeon··on How I prepare a talk for a tech conference (2022)
Pet peeve: During Q&A, the presenter should repeat the question. Even if the asker has a microphone, they are often not clearly audible. Repeating the question, or a brief version of it, lets the audiences, both present and via video, hear it clearly, and shows that the presenter heard and understood it before they answer it.
dmckeon··on The history of lead pencils and their lack of any lead (2021)
Fun fact: Henry David Thoreau's family was active in the pencil-making business in the 1820..1850 timeframe, and Henry D. made several innovations in the art.

dmckeon··on Topologists tackle the trouble with poll placement
In my opinion, wait times for voters of more than 30 minutes should be grounds for civil suit or impeachment of the election officials responsible. Other variables of interest would include voter dwell time - the time it takes for one voter to cast their ballot - and the likelihood of machine malfunction, whether from inadequate preparation or maintenance, or from active sabotage by voters. Worst case is a polling place with minimal staff, fragile and antiquated machines, and a high proportion of impatient, frustrated, or angry voters. The procedure for repair of machines (never use the word "fixed" during an election) is to mark the machine as out of order, call the elections office, and begin a long wait. For non-Americans, note that US general elections typically involve 2 or 3 dozen contests, so marking paper ballots just for one party or another is not an effective option in the US.
dmckeon··on The ü/ü Conundrum
For similar sounding names, this fuzzy match is pretty effective. https://www.archives.gov/research/census/soundex
dmckeon··on Grade inflation at UC Riverside, and institutional pressures for easier grading
One approach to requiring prerequisites is to give a test on the prerequisite content on the first or second day of class, with the test scored quickly, and the results worth 20% of the final course grade. Students who do well on the test know the prerequisites, and those who bomb the test have time to drop the course and enroll in one of the prerequisite courses - or to stubbornly struggle with the higher-level material and earn a B grade. It takes some cooperation among the faculty to pull off, but can be effective.
dmckeon··on Nassim Taleb says the U.S. is in a ‘death spiral’ over government debt
Congress-people have few incentives to restrain or reduce the national debt. There is plenty of talk, but little action. The event horizon may be distant, but the pull is inexorable. What could possibly solve this? Could we give representatives and senators bonuses for spending less and taxing more?
dmckeon··on Train robbery for Amazon packages? More common than you think
It would be interesting to see train conductors on electric mountain bikes, with drones scanning each side of the stopped train for damaged or cut air hoses, hotbox bearings, etc. Could save a lot of walking, if the railroad and the union agree.
dmckeon··on Mouse filmed tidying up man's shed every night [video]
Note the temperatures - 5C, 41F - is the mouse tidying, or trying to build a nest in what might be a styrofoam container?
dmckeon··on The surprising genius of sewing machines [video]
There is an excellent book that covers the topic: The Fabric of Civilization, by Virginia Postrel. The part most amazing to me was the pyramid effect of fabric production in the days before mechanization - 20 spinners per weaver producing thread, 80,000 spinners near Manchester alone, thousands of weavers turning thread into fabric, etc., and as the spinning jenny and later the power loom came along, employment and economic patterns changed drastically, giving us the Luddites and similar movements. One wonders what programming will look like after 10 or 20 years of AI.
dmckeon··on When a postdoc in my lab committed fraud, I had to face my own culpability
Publishing reproducible research would disincentivize fraud by providing a clear way to expose fraud, and could tend to benefit other researchers in the field, by effectively sharing specific methods as well as results.

Incentivizing reproducibility would be hard as a grassroots effort, but would be enforcible if it were tied to funding. Even if only a small percentage of published studies were reproduced, and only a small percentage of them were found to be fraudulent, the disincentive for fraud would be present. We do not need more Andrew Wakefields.

> Effective checks would basically mean science costs 2x as much.

By that logic, we would need to enforce speed limits by having one police cruiser following every driver.

Dual dash-cams with high-endurance SD cards can help with auto liability. If your auto policies only meet the state limits, or your home insurance has not kept up with market values or replacement costs, perhaps talk to an independent broker, and ask about an umbrella policy as well.
dmckeon··on When a postdoc in my lab committed fraud, I had to face my own culpability
Rather than an post-hoc investigation model, how about promoting reproducibility in publication, with an expectation that others can run the same study with identical equipment, models, codes, playbooks, etc. For PIs getting government funding, true reproducibility should be a requirement, and other researchers should be funded to report pro or con on the reproducibility of studies, and then ethical lapses could be much more visible. Science based solely on faith in the ethics of other researchers is just religion with more complicated rituals.
dmckeon··on 'It's unhinged': is the book world turning against Goodreads?
Newspapers and reviewers published in them have exposure to their reputations. Readers who get advance copies may have no reputation to care for or defend. Book publishers could send a few one-time codes with each advance copy if they wanted attributable reviews instead of astro-turfed buzz. Knowing the various incentives, I won't hold my breath.
dmckeon··on 'It's unhinged': is the book world turning against Goodreads?
That Goodreads accepts reviews for books that have not yet been published tells me almost everything I need to know about them.
dmckeon··on Homes need to be built for better internet
Put a patch panel in the structured media center, attach all house Cat-5++ cables to it. Put in-wall keystone RJ-45 receptacles at the other end of each cable. Put ISP router/gateway/wifi box at some central location. Use patch cables and panel to connect ISP box to ISP. Add WAPs elsewhere as needed.
dmckeon··on Report Phone Spam – Shut down robocallers and text spammers
My spam calls are down to 1 or 2 per month after using nomorobo.com for 5 years. It is not direct action as TFA suggests, but it works well for me. Callers reach voicemail, almost never leave messages, and the phone almost never rings. Free for VOIP numbers, $20/year for mobile. Several similar alternatives exist.
dmckeon··on Trading bot that buys stocks bought by politicians is up 20% since May 2022
Okay, make that spouse instead, because spousal immunity. Also, make the funds' holdings temporarily blind: a fund does not reveal the entirety of the holdings in its portfolio until 5 years after year-end, and waits 3 months after the closing of a position to reveal that it held XYZ, Inc. during a 37 month period. The idea is not to try to exactly match "the economy" with "the market" or even with "the funds" but to disincentivize politicians making any direct connection between their work and with individual equities, while still being able to benefit from general economic growth.
dmckeon··on Trading bot that buys stocks bought by politicians is up 20% since May 2022
Radical proposal: Rather than trying to police leakage of insider information, level the playing field for both politicians and fed employees by creating a dozen or so national mutual funds of at least 1,000 equity positions each that intend to model the US economy as a whole. Anyone can invest in them, but all US Federal employees and immediate family members are required to liquidate all other positions and hold only national funds. If the economy and funds do well, all federal folks profit. Distribute fund management among multiple fund management firms.

For flight to a destination, it may be possible to use an altitude with a more favorable wind direction. For landing, the aircraft approaches a mooring mast from downwind.

dmckeon··on Ever-Enduring Dürer
Dürer made some choices that should appeal to entrepreneurs: he was perhaps the first artist to explicitly sign his work, and did it with with his own brand, the stylized A/D. He also chose to work in printmaking, thus being able to readily reproduce his works more rapidly than any painter. His work is wonderful, but too many art commenters focus only on the art, and miss his commercial innovations.
