CaptainJustin··on DARPA has caught a Gremlin drone in midair
Can you imagine how this would the increase the search radius of a air rescue mission? One search and rescue flight looking for survivors could launch a half dozen drones each extending the explored area by thousands of square kilometres per hour.
CaptainJustin··on Amazon copying products/rigging search results
Rossman raises some interesting points here that got me thinking.

I wonder if we need to split companies up that want to play across too many layers - Amazon owns the (1) infrastructure platform (AWS), (2) the marketplace (Amazon.com) and (3) is creating products in the marketplace.

If that were the whole story it might be ok. From the Reuters article it would seem that Amazon uses marketplace backend data to benefit their product design. Add to that Amazon.com's dominance and gravity and I have a problem with this.

CaptainJustin··on Google introduces mandatory 2-Step Verification for Google Accounts
1. What is the official way we're supposed to handle this?

2. How should the tech world communicate that better so that it's more user-friendly?

CaptainJustin··on PostgreSQL: Kubegres is available as open source
I love this sort of thing. Something I appreciate is looking through the resulting YAML config at the best practices and rich experience by the team that wrote it.

It reminds me of receiving "golden images" from vendors with a precisely best-practice install and configuration of their software.

CaptainJustin··on Xata – Database service for serverless apps
Looks similar to Firestore - identity aware, serverless, pay as you use.
CaptainJustin··on Useful Spy Books
> n.b. I always find it funny how interested and intrigued yet abhorred so many people are when it comes to spycraft/espionage etc...

I was such a person. When I was in school I read the EU report on Echelon. There was so much basic espionage meta in there that shocked me. For example I had thought of signals intelligence as an aggressive act - an act of war. In the EU report SIGINT and broadly spying was introduced as a ordinary part of a decent intelligence function of a state.

CaptainJustin··on MDMA reopens child-like “critical periods” in the brain
What does `pep` mean in this context?
CaptainJustin··on Ask HN: Responsible Discolure Without Compensation
From their perspective it might feel a bit like a hostage situation: "I found a way into your house. How much you going to pay me tell you how?"

From your perspective I would imagine that exploring the vulnerability, packaging and capturing the steps-to-reproduce are all work. Work should be paid for.

In summary, I don't think they can make demands of your time and effort by requiring you to package and share. But don't let it sound like a you have anything they have a right to or that you're holding anything hostage.

CaptainJustin··on Apple plans to scan US iPhones for child abuse imagery
Also, we've seen more and more AI hardware being shipped built-in to phones.
CaptainJustin··on gRPC benchmark results
You are correct. Some of this has changed significantly somewhere between Java 8 and 16. For example the Java applications we're running against Hotspot 16 regularly gives memory back to the host. It's GC pauses are also quite insignificant now for a microservice regularly allocating and GCing.
CaptainJustin··on Facebook does not plan to notify half-billion users affected by data leak
I hope the fines are enough for them to ensure this doesn't happen again. Personally I don't have a Facebook account because I don't trust them anyway but I think the people who have one probably didn't want this to happen.
CaptainJustin··on Egypt holds grand procession of ancient mummies in Cairo
I would normally agree with a statement along these lines. However I would like to think that this came out of the marketing budget for the tourism sector. I bet tourism is significant to Egypt's economy.

Then I think the question becomes: Was this an effective marketing event? Who knows. But considering someone from South Africa is discussing it with someone in the Netherlands on HN perhaps it worked out.

CaptainJustin··on Bronze Age mining sites received deliveries of pre-processed foods
This topic has occupied me for the last couple years. It started with "1177, The Year Civilization Collapsed". I went on to read material from archaeologists reporting in a rather dry way on their findings from the time / region.

Some of the things that blow me away is the sheer scale of the late bronze age: The massive cities, the trade fleets, leaders sending each other gifts, the exchange of skills between regions and the massive trade routes for tin, copper and bronze. It completely destroyed the anglo-centric epochism I was taught in school.

And in a short time it all collapsed. We don't see that level of trade, size of ships, cities of that size, level of diplomacy etc etc for well over 1000 years.

CaptainJustin··on When ICE asks Google for your user information
I am gradually getting myself out of the FANG world. What do you do about the duopoly (is that right?) of the A+G? The two of them own iOS and Android. Not sure I can have smart phone today without one of them involved.
CaptainJustin··on DARPA now has AI-controlled F-16s working as a team in virtual dogfights
I was thinking through something recently. Here's where I think things are going:

- I suspect that air platforms will be littered with censors and massive amounts of data will be collected.

- This data will be used to train AI to complete missions.

- The USAF will start by augmenting human-led teams with AI flown aircraft.

- Polyglot teams consisting of platforms with different roles in the same mission.

All of this has led me to believe that the countries that engage in the most air missions (most combat active air force) could ultimately have AI models orders of magnitude better than other countries.

It would be great to hear someone who knows more than me (not hard) interrogate this idea. I've been captured by it and I'm meandering down the road of possibilities that start there.

CaptainJustin··on GitHub, fuck your name change
I know it's anecdotal but I've asked my colleagues the same - in a country with a terrible history of this sort too. And turns out I can't find a single person who agrees with Github's decision.
CaptainJustin··on Seasonal energy storage in aluminium for 100% solar heat and electricity supply
With over 38M [1] households just in Germany that would come to: 19 million metric tons of Al.

Each year the people of this planet mine 160 million metric tons of Bauxite [2]. Not sure how the Bauxite ore related in weight to the final product.

Maybe this could be a viable option for some energy storage?

CaptainJustin··on Title of Elon Musk Has Changed to Technoking of Tesla
> Elon and Zach will also maintain their respective positions as Chief Executive Officer and Chief Financial Officer.

I suspect King of Technology - but perhaps he's creating a grey area to give himself lateral tactical space to negotiate his posture against the SEC.

CaptainJustin··on San Francisco DA Chesa Boudin recall campaign approved
Maybe this one will work: https://www.sfchronicle.com/crime/article/Campaign-to-recall...
CaptainJustin··on Building a high-scale chat server on Cloud Run
My Go-based containers start in much less than a second. I believe its dozens to maybe low hundreds of milliseconds
CaptainJustin··on Tailscale on NixOS: A New Minecraft Server in Ten Minutes
You're pretty much there.

Lots of kids and people without public IPs they can write NAT rules for setup Minecraft servers at home etc. This is the classic example that can be solved with ZeroTier, TailScale etc.

CaptainJustin··on Ask HN: Do we need a Google Customers Union? Could it work?
I guess but maybe that makes the news and it gains more traction?

Also, is there any evidence that Google censors search results?

CaptainJustin··on Ask HN: What do you self-host?
Running a few different containers in Docker at home.

- Hand-rolled Go reverse proxy with TLS from LE.

- Several Pg DBs for development.

- VPN server.

- Chisel for hosting things "from home" while running on my laptop remotely.

- Etcd

- Jenkins

- Gitea

- Pi-hole

- A few different development projects

CaptainJustin··on Former developer at software company deletes his code to protest its ties to ICE

CaptainJustin··on Oracle's New Supercomputer Has 1,060 Raspberry Pis
Not sure what they used.

In my tiny 4 Pi cluster I'm using a regular 1U server PSU. It supplies 5v and can easily supply the current needed for the four Pis.

CaptainJustin··on Why Go and Not Rust?
People may also mean different things by scale.

For me, scale means more micro-services. For another person it means a bigger monolith.

CaptainJustin··on Everything I googled in a week as a professional software engineer
I appreciate this as some newer developers I have worked with have been concerned that Googling things is something they need to grow out of. Google engineers, being somewhat revered in my Big Corp, Googling things every day would go a long way to encourage them.
CaptainJustin··on [dead]
Not being first doesn't mean you're not onto something. In fact. It may mean there is a market and someone is playing there. Finding it's already being addressed may in fact be a wonderfully affirming thing. It validates the problem and possibly your solution to it.

Consider this as well. If you're the first to solve a problem or the first to propose a particular solution you're going to have to educate / explain it to for every conversion. That's hard.

CaptainJustin··on Divers Find Remains of Ancient Temple in Sunken Egyptian City
Vlad's videos are amazing. I think he's explored quite a bit that is difficult to find much on.
CaptainJustin··on Google Cloud networking issues in us-east1
It's quite common in cloud solution design to design for failure. One of the common assumptions that we hold to is that one region may go down. Other examples: Assume an instance of an app can go down. Assume a VM can go down. Assume a DC can go down.

This is not to excuse the downtime in any way.
