My opinion that is biggest fete of engineering in the last decade. Amazing
larrydag··on Super Heavy has splashed down in The Gulf of Mexico
For comparison the Statue of Liberty is 93m. Big Ben is 96m.
larrydag··on Fortran vs Python: The counter-intuitive rise of Python in scientific computing (2020)
Absolutely. Fortran about 500 lines of code vs <20 lines for Python. The ease of use and flexibility of Python across so many application types makes for a good reason for its popularity. The rise of hardware computing performance makes speed tradeoff trivial.
larrydag··on The Apollo Syndrome
In the finance and banking world a lot of the larger decisions are done in committees. These committees usually require a majority vote to get things approved. Most of the voting members of the committees are the Execs. You can imagine the political and bureaucratic intertwining of getting things done in these organizations with those types of personalities.
larrydag··on Please don't use AI to get on the global leaderboard
Agree. Just create a leaderboard division that includes AI. Don't fight it. Embrace it
larrydag··on Texas officials warn of rolling blackouts to ease strain on power grid
That's a big "if". The cold temperatures in Texas in 2021 was the first such experience in nearly 70 years. It was a very, very extreme condition.

larrydag··on OpenAI's board has fired Sam Altman
This seems to make more sense. Perhaps it has to do with OpenAI is not "open" anymore. Not supporting and getting rid of the OpenAI Gym was certainly a big change in direction of the company.
larrydag··on Nuclear Conversion for Starship
What are the safety ramifications? Is there not a radiation fallout from the exhaust?
larrydag··on Generating Income from Open Source
I've always looked at charging for open source as a support service. What is the developer's time worth? If one wants new features pay a fee/salary/bounty for the development.
larrydag··on Microtiming in Metallica's “Master of Puppets” (2014)
Apparently due to these timing challenges in that album Lars Ulrich does not like playing Eye of the Beholder live.

larrydag··on First Solar Bike Path in Germany Is Now Live
When structures like this is built is a lifetime cost taken into account? I'm wondering if after a while it's going to fail or prove too expensive to maintain.
larrydag··on America Faces a Debt Nightmare
The worry is that one day congress won't have that luxury for one reason or another. The uncertainty is when and what means. It is the uncertainty that causes economic panic.
larrydag··on Plane Lands/Takes Off in Only 20 Feet (2013)
I believe the key is a strong headwind. I would like to see if this could be accomplished without the headwind. I believe short takeoff is possible but not quite that short.
larrydag··on Ask HN: What's with the DIY state of the art long-range Wi-Fi?
Here is a write-up of the NYC mesh network

larrydag··on Best and worst decisions I’ve made
As a parent and a dad I really appreciate point #1. It's hard to explain for those that don't have children and it's immediately apparent for those who do.
larrydag··on “Blue Light” creating capacity for nothing (2007)
The article's story anecdote of "blue light" is about finding the true value in a process. Blue light means the welder is actually creating value in the product. Anything else in the process does not help build value to the product. It is all non-value added activities. The non-value added activities might be necessary such as setup, delivery, reposition or what not but it doesn't drive value. By maximizing the blue light welding operation it maximizes value being created. Maximizing value will minimize extraneous activities that don't help make a finished product and should decrease cycle time for the value-added activity.

This all can be learned from The Goal by Goldgratt which is a story about theory of constraints.

larrydag··on Watching the Greatest Hits from the Last 120 Years
Looking at the list it's interesting to see how much sequels have taken over the box office
larrydag··on Principal Component Analysis explained visually (2015)
I really like the way Harrell uses PCA to build regression analysis in Regression Modeling Strategies

larrydag··on The architect who became the king of bank robberies
Has Leslie's life been made into a movie? I would certainly watch it.
larrydag··on U.S. Ship Sunk by Germans in 1917 Is Found Off English Coast
There were so many war crimes in WWI. I'm sure partly the reason why they called it the war to end all wars first coined by HG Wells.

larrydag··on Ask HN: Are Linux HowTos dead? Why?
Personally I believe Linux has matured to a pretty decent usability level for the average user. Ubuntu, Opensuse, Linux Mint and some of the like have taken a lot of the hard work out of managing and installing a linux OS. It used to be that you would slave hours of getting your specific hardware to work with a particular flavor of Linux. Now you have drivers that are plentiful and up to date, bugs that get fixed fast, and large communities at near enterprise levels maintaining the updates. Frankly a pretty good time to be a Linux user.
larrydag··on Ask HN: What are the best tools for web scraping in 2022?
The polite package using R is intended to be a friendly way of scraping content from the owner. "The three pillars of a polite session are seeking permission, taking slowly and never asking twice."

larrydag··on Why wasn't the steam engine invented earlier? Part II
Advances in manufacturing processes is often overlooked in the industrial age.
larrydag··on Ask HN: How do you search for products / apps given a list of requirements?
Find a user group, hobbyist group, or consortium in that domain and ask them for their recommendations. Domain search technology is great but nothing can beat asking someone or some group that has been using the niche product for years.
larrydag··on Hollywood doesn’t make movies like ‘The Fugitive’ anymore (2018)
Agree and the second film was most egregious.
larrydag··on Hollywood doesn’t make movies like ‘The Fugitive’ anymore (2018)
Wasn't the Jason Bourne films character driven adult action? I found those films compelling because I felt I was discovering Bourne's character along with him.
larrydag··on Ask HN: What are examples of common beliefs conclusively invalidated by data?
The Flaw of Averages states that: Plans based on the assumption that average conditions will occur are wrong on average.

larrydag··on Ask HN: What news subscription is worth it?
The primary Dallas local is the Dallas Morning News
larrydag··on 40% of California's small businesses died in the last two years
I saw that yesterday and it said the data was produced by Womply. I can't find the source though.

BUMP: could this be it?

larrydag··on YouTube cancelled my Nextcloud installation how-to
If this were the practices of a startup, new biz, or small org and tried something like this they would not make it at all. Is this because of monopolistic practices? Why do they believe this behavior is good for business?

My question is the creator content video space in need of competitors? Some other products are making options available such as Rumble and Vimeo.
