nelsondev··on Why Machines Will Never Rule the World – Artificial Intelligence Without Fear
Scenario 6:

The super intelligent AI creates an even smarter AI, which replaces the parent, and so on and so forth, forcing the AI into an endless series of reproduction.

Rename it as “verified speech transcripts.” I don’t need to understand video codecs to watch Youtube.
nelsondev··on Stable Diffusion Public Release
Looking forward to a future where all a politician’s quotes are on a blockchain, signed by their private key, and they chose to do so voluntarily out of fear of deep fakes.

Will remove all the useless “I didn’t say that”

nelsondev··on Sudden increase in number of mid-air diversions to Hawaii
Last year in June, my Hawaiian airlines flight leaving Honolulu turned back after 30 minutes into the flight.

No explanation was given, but they put us on a different plane about 3 hours later. But the experience was terrifying to be honest, when the pilot says we are turning around, and there are only miles of ocean in all directions.

nelsondev··on How Discord supercharges network disks for extreme low latency
Cool solution! Almost like cache wrapping a hard disk.

I am curious as to why they can’t tolerate Disk failures though, and why they need to use the Google persistent storage rather than an attached SSD for their workload.

I would have expected a fault tolerant design with multiple copies of the data, so even if a single disk dies, who cares.

nelsondev··on Don’t call it a comeback: Java is still champ
The p50 speed up from delaying memory management comes with a trade off, namely you get Garbage Collection pauses, bad p99, and spend your effort tuning the Garbage Collector instead of your code.

As for comedy in books, I find Bukowski - Post Office to be quite hilarious at times.
nelsondev··on US prison workers produce $11B worth of goods and services for little to no pay
Free “room and board” is a form of compensation.

RA’s (Resident Advisors) at American universities, students whose job is to handle dormitory issues, are compensated via free “room and board.”

nelsondev··on My students cheated... a lot
This solution just moves the problem from colleges/universities to a “board”, but doesn’t solve it.

People would still cheat on the hypothetical licensing exam.

Licensing also would add friction in changing jobs, immigration policies, thereby hampering general mobility of workers. More paperwork and bureaucracy would develop.

A company’s interview process is currently where someone’s declared skills are put to the test, which although imperfect, provides the filtering mechanism you’re looking for.

nelsondev··on Ask HN: What to do about ‘Good at programming Bad at Leetcode’
To second this point, part of being a good programmer means picking up new skills quickly, and then applying them.

Leet code is very contrived. However, learning leet code, then applying it in an interview shows you have the aptitude to learn quickly.

nelsondev··on FAANG promo committees are killing Kubernetes: A Short Thread
There were multiple factors, hard to know what percentage gender contributed, but I do think it played a role.
nelsondev··on FAANG promo committees are killing Kubernetes: A Short Thread
When selling your work to a promo committee, building a new shiny thing lowers the communication hurdle.

Personal anecdote, at Amazon, my wife led a very challenging refactor of legacy code and didn’t get promoted, I built a shiny thing barely anyone is using yet, and got promoted.

nelsondev··on Ask HN: When did 7 interviews become “normal”?
That can work for some, but imagine you already have a job, and time commitments, and it takes 5-10 companies to find a fit.

Spending ~1-2 months is expensive.

nelsondev··on Show HN: We made an open-source personalization engine
Very cool! Thanks for sharing.

Rather than an offline model, why not use an online, continuously relearning model like a Multi-Armed Bandit to do the re-ranking?

This just happened. (In Canada, not the US, but similar countries.)

Here is a story about police rounding up protestors and sending them to jail.

https://news.yahoo.com/police-arrest-dozens-blockading-canad...

> Police chief: “Last night we began to take additional actions towards implementing our operation. We moved officers and equipment into key positions throughout the city and took up 100 checkpoints around the downtown core. We began making arrests of key individuals who were responsible for organizing these unlawful activities. (flash) As of 3pm today we’ve arrested 70 people. They’ve been charged with multiple various offenses including mischief.”

Here is a story about accounts of protestors being frozen, preventing them from paying bail to get out of jail.

https://www.nytimes.com/2022/02/22/world/americas/canada-pro...

> But for one protest organizer who was arrested last week, the effect was more immediate. The organizer, Tamara Lich, said she had been frozen out of all of her accounts and could come up with only 5,000 Canadian dollars for bail.

Two wrongs don’t make a right.
nelsondev··on Fresno lost $400k to a phishing scam in 2020 and never told the public
You can focus on both the “how” and the “who”. I work in an engineering organization where when something sufficiently complicated goes wrong, we do a proper root cause analysis, ask 5 Why’s, propose process improvements, etc.

But sometimes, people just screw up, and preventing every unique screw up, would mean the creation of an absurd amount of process.

For example, one time, excited by the performance results of a colleague, I tried to immediately apply his performance optimization in a different context serving production traffic; we had a team culture of don’t test in prod, etc; but my hubris/excitement meant I powered ahead, which ended up driving up latency, failing requests, and causing a small outage.

The solution in this case isn’t to invent a new process to prevent my mistake, but rather to make sure the engineer knows they screwed up. A bit of shame/guilt leads to self improvement.

If you focus solely on process, and avoid personal responsibility, you may end up missing opportunities for personal growth.

Why shouldn’t there be accountability of the person who failed to disclose?
nelsondev··on Electric fields, not individual neurons, may hold information in memory: study
Does there have to be a persistence layer if the machine is never shutdown?

If all our memories are stored in “RAM” and never flushed to “disk”, we may never find evidence of “disk”.

nelsondev··on Electric fields, not individual neurons, may hold information in memory: study
Reminds me of this article, where spies abroad all suffer similar strange headaches, impacting their ability to focus.

Perhaps your “hypothetical” bioweapon is already being tested in the field.

Did you read the linked article? It’s not proposing a new tool, just using rules/filtering to categorize into inbox (humans), paper trail, news letters.
nelsondev··on Dad takes down town's internet by mistake to get his kids offline
Just curious, when you tried explaining to your child the importance of sleep and negative health impacts of late night social media, what was the reaction?

I’m curious what led to wifi being turned off rather than kid personally convinced to do it.
