FYI: firm landings are actually correctly done, especially with rain or drizzle. It should not feel like a crash though.

The worst landing I ever had was when I landed with no sensation of touching down on the runway (a zero feet rate of descent.) Both myself and my CFI went nuts trying to figure out if we were down, or still flying along the runway and about to bounce.

In SV it's rare to pay for commercial OS or other support due to the scale. I have never worked anywhere that paid for anything, whether it's RHEL or Cloudera or whatever, unless it's only available as SaaS/Cloud.

That's why working at FB or Google is like going back in time as far as monitoring UIs, etc.

Some of the clever large companies took advantage of "site-wide support licenses." For example, Netflix paid MySQL AB $40,000/year for MySQL site support so they didn't have to hire any MySQL DBAs. Just keep filing support tickets. :)

The FAA/NTSB investigates basically every crash

No. The NTSB investigates significant accidents (either commercial operations or passengers involved.)

There's an average of 400 GA accidents per year, so about one a day.

If two CFIs climb into a Piper and crash, it probably won't be investigated. Add a passenger, then the NTSB gets interested.

I read the article.

The significance of the recent mathematical advances, especially topology, is that somebody will be born and combine them into a major advance later.

The article is a bit misleading to laypersons in that pure math (topology and countability) and computer science have almost no overlap in the short term.

Pure mathematicians don't use computers or even think of them in their work, for the most part. It's up to applied mathematicans to read their proofs and do something concrete later, if applicable.

I've initiated "process improvements" a few times. It's always unpleasant since you're rocking the boat (kinda like when you report a security issue to a company with no established process.)

- got Royal Bank Canada while I was there to star out account numbers on ATM receipts. Had to find a competitor's receipt first (CIBC) and show a senior manager to "prove" there was an issue.

- shortly after leaving Netscape found email parsing bug and submitted that to a an ex-coworker who channeled it to the right developer.

Stay tuned for some more in process.

was sworn to the bar without actually going to any sort of law school.

It can still be done today in most US states.

Also, note that even the self-represented can take on a government and win. See Jim Pattison's (Canadian billionaire) tax hearings vs. the Crown (Canada), which he won after a decade of litigation. Multiple prosecutors and judges retired during that time period.

Besides developing further tax filing methods for his empire, you can bet he wasn't sued again by the government - they hate taking a loss. (The US SEC infamously tries to undermine defendants today by going after their ability to pay lawyers before trials.)

This is huge.

Ontario is the "California" engine province of Canada, similar in geographic size and sophistication. It subsidizes the rest of Canada (the "have-nots"), but it can afford to do so.

To give you an idea of how sophisticated Ontario is, most Hollywood comedians and a large percentage of writers are originally from the Toronto, ON area because of their writing and self-production abilities.

Ontario universities have a direct brain-drain pipeline to SV, but this will help them return later in their careers.

They still need to hire.

But they don't need to hire in NYC, and companies look at other regulations when deciding head count.

For example, you'll see a lot of startups freeze hiring at employee #49, since in the US (and other countries), there's a ton of HR requirements that kick in, including submitting IRS documents on magnetic tape.

One of Netscape's early advantages was that since they knew they would hire thousands of people, they skipped over all of the entry-level HR systems and started with enterprise-level systems. It was controversial at the time, but turned out to be the correct decision (the first exec was from SGI, so knew what growth looked like.)

How much aeronautics/airworthiness/safety R/D is actually conducted by the FAA?

Virtually none. It's widely recognized that airine mfg. technology is a rapidly moving target, and the FAA is not in the airline mfg. business.

The FAA is in the business of collecting and reviewing certification data, which is why the fake MCAS paperwork is a really big deal.

NASA operates the X-planes R/D program, not the FAA.

This post ought to be the final nail on the coffin of the cult of leetcode/whiteboard style inverviewing.

Looks like he has ADHD. Maybe somebody with more time can go through his blog post line-by-line and figure out what's going on.

Most of my Coderpad stuff compiles and runs the first time, so I don't use his incremental test method, or see a need for it. Maybe he learned programming on heavy-weight IDEs and got trapped mentally in those?

Nonsense. The Democrats are deliberately ruining cities through their BLM, antifa and activist DA proxies, including in Silicon Valley. What could be more relevant to HN than that?

dang, I've noticed that you come out on the wrong side of just about every major issue. Do your homework - this is not Communist Russia, where HN wouldn't even be allowed to exist.

FYI: for readers who are unaware, the first covid-19 sequence released from China was unauthorized - he released it through a partner lab in Australia. The research scientist immediately had his lab in China raided and he was fired.

So the CCP was not only active in continuing international flights while domestic flights were halted, but the CCP was actively suppressing patient counts and the sequence itself.

I lived in an apartment building that had an old ICE car with an electrical problem catch fire at night, then explode. Flames were 20' high.

Luckily it was parked under a carport area, so destroyed the carport roof and adjacent laundry building, and not the residential building (just singed.)

It took about a year to deak with the insurance adjuster and rebuild.

The top pic appears to show a steel barrier around the mineshaft opening, although it also looks roughly like a multi-level "Chinese gold washing machine."

The latter is a low-cast static set of table(s) that water can wash metal flakes with no moving parts, and is popular for its low cost or use in areas with no mechanicl parts supply. So gravity is used to separate materials, similar to how river bends make alluvial gold deposits. Early ones were made of wood, but steel would also work.

You can see YT videos of a similar design in the defunct Cornwall tin mine.

(In ancient/olden times, the main industrial metal was bronze, alloyed from copper and tin. Tin is very rare since it has an odd atomic number, with the historical mines being in Afghanistan and Cornwall. Before the Iron Age, Cornwall could have been the "El Dorado" of its time. Iron/steel is found everywhere on earth except Japan, so steel democratized industry across Europe and Asia, but Japan had to start WW2 for it.)

(Most gold mining is collecting flakes, not nuggets. 1 gram per ton is usually considered commercially viable, and more makes it dramatically moreso.)

It's leading to forcing the CCP to honor trade and territorial agreements, which they have never done.

Trump was able to bring the CCP to heel, it will take either him or DeSantis to continue that in the next administration.

The arms race in the Indo-Pacific region was caused by Obama failing to honor the US defense treaty with the Philippines. Now every country in that region is building ships and subs.

Currently, China uses the US dollar for over 91% of business outside their country, which makes US capital controls the CCP's greatest weakness. With the stroke of a pen, a US President could cause China to implode, including the end of the BRI debt-trap projects.

I've been following this pretty closely, both because I live in SF and an acquaintance owns a unit there.

The situation is very bad.

Around 2 weeks ago a city engineer for the first time mentioned "possibly dismantling the building", because logically you just can't have a skyscraper that's unsafe in the middle of downtown SF. It threatens numerous other tall buildings.

Based on videos I've seen of the Kobe earthquake, liquefaction would destroy the building even if tilting didn't decommission both the elevators and plumbing first. I wouldn't occupy anything in its shadow.

This is an asylum/immigration crisis and EU is a group of countries whose views on asylum and immigration politics are very divergent.

They're economic migrants, same as the other 10 million who've illegally entered the EU in the past decade. Stop conflating them with asylum seekers.

Conflation is a Marxist technique: in the UK, one official deliberately conflates economic migrants with surgeons, "Some of them might be surgeons. Why wouldn't we want surgeons? What's wrong with you?", despite less than 0.01% being surgeons.

You could argue that Nixon improved relations with China to counter-balance USSR influence during the Cold War.

It was obviously foolish to help China become an economic power since the CCP has been at war with the US since the end of WW2 (2 Taiwan Straits wars, 2 Korean wars, Vietnam war), largely driven by Maoist ideology. (The USSR was involved in stopping the Straits wars to prevent wider conflicts.)

(The USSR dealt with an aggressive CCP by obliterating their forces during a border conflict using overkill. The CCP doesn't understand anything less. The USSR also planned to use nuclear weapons on Beijing around 1969, but the US intervened.)

I followed outsourcing to China in the business press from about 1972 to 2000. I shook my head at the end of each article. But here we are.

What's important to realize is that both the CCP and Russia make public statements and:

1) they're either obviously hyperbolic or

2) they accurately represent their actual plans.

#2 is not well-understood by our politicians for some reason. Pompeo is one of the few people to get it, hence the US' very effective strategy for the CCP during the Trump administration.

Note that China has structural weaknesses that will diminish its power: they import 50% of their energy and food, and have a demographic problem that could cut their population in half. They also have serious flooding issues, with 100,000 questionable dams built since 1945.

And the US can currently only make one F-35 per week, while in WW2 the P-51 was literally stamped out.

Note that half the time, you'd make typos and it wouldn't run. So it sounds nostalgic, but not so much.

However, debugging it helped to learn the language. :)

Dr. Dobbs Journal was probably the king of source code listings in magazine format.

Pre-Internet, there were some remarkable mass-distribution Unix magazines with significant source code for utilities: Unix Review and Unix World. Even today, the back issues would be useful.

I remember lusting over the AT&T 3B Unix machines advertised in those, but never could afford one. So I waited until VAX Unix in uni (the arts dept. had an unused one), then SCO and Linux.

1) When I do consulting for profs on campus, I ask for a uni library card.

This is important because many students today are fearful of other people even when on campus transit with a driver, so you better have a verifiable reason why you should be there.

2) University cops in the US are usually real cops - armed and authorized to arrest or shoot you - not "mall cops."

Correct. Cisco stock growth is not only limited by the hw business since 2000, but Huawei ate their lunch on growth, which is the kiss of death for a tech company. See Nortel.

(Zoom was started with 40 Webex (Cisco) engineers. lol.)

Also Cisco salaries are really low for SV, like 30% less - totally non-FAANG. I've pointed that out to Cisco recruiters, and they almost cried on the phone begging me to go to the next interview step anyway.
