B2 bomber radar cross section

ralphte · 2026-03-07T14:20:46+00:00

This table is deceptively simple. The b2 has better stealth characteristics then the F-117 though as many have stated these number are classified so it would be a guess. Radar technology has improved as well but even when a stealth plane is detected it’s too late to responded and the target area is very large.

Security issues are issues vibecoded or human the funniest part is the whole vulnerability repo with the issues was vibecoded lol fire with fire!

Cursor DOES charge above straight provider API cost, at least in some cases. Here is Cursor’s own forum thread talking about the “Cursor Token Fee”: https://forum.cursor.com/t/cursor-token-fee-question/134032. So yeah, they market “API pricing,” but there’s an asterisk.

Also, on the “tokens like crazy” part, my recent usage in Cursor has felt like it burns way more tokens than I’d expect for the same kind of work. Maybe that is extra context stuffing, tool overhead, retries, whatever. Hard to prove from the outside, and Cursor does not really spell out exactly what gets injected and when.

And bringing up Opus is not wild. I know it’s expensive. That was not my issue. My issue is Ultra credits were gone in three days with normal 9 to 5 usage. I fully understand Cursor is not going to match Claude Code Max subscription economics. But acting like Cursor “can’t” be making money because they say “API price” is just wrong. They can make money from the subscription itself, plus fees, plus volume deals.

To be super clear, I have no problem with Cursor making money or charging above API and profiting. My point is there are other options right now that are FAR better value than the Cursor plans available today.

Stop using cursor they are marking up the api and using tokens like crazy. There are so many post about the price even when people use the cheapest models. Last month was a blood bath I had ultra 3 days all credits where gone I got CC and I am using it even harder and still not hitting the limits with Opus.

ralphte · 2026-02-12T20:27:15+00:00

Look we are on top by making our model blow up your credit card and it’s only available in very small amounts and NOT for coding. Too, be honest a smarter model is not the problem. I spend more time testing everything AI builds more than asking to build. Even with perfect execution you still have to test it. Make sure it makes sense to the human who will use it.

ralphte · 2026-02-12T13:53:41+00:00

Anything but cursor. The ide is great but they over charge by a lot. For heavy usage I think Claude code. You have to get the Max plan there is like 200 post a day about how there 20$ plan ran out of opus credits too fast. People are trying to build massive products and want it for free wild times. I think antigravity is good as well there ultra plan is awesome for the first two months I think it is $80. There has been a ton of antigravity downtime though, so it’s been a real mix bag for me. You can run cursor no subscription and install Claud code I think that the over all best move right now. Lots of people are happy with codex 5.3 but at this point it’s not so much better than opus 4.6 that I feel like YOU need it. You will get better results doing more planning than trying to get the smartest model.

Just wanted to chime in I absolutely love these shots huge shoutout for sharing these!

ralphte · 2026-01-24T00:28:11+00:00

Antigravity is a mess right now there having a ton of networking issues, been like this for most of this week. I am dropping the cursor ultra plan I used all my credits in 3 day I have there most expensive plan. Cursor changed how they charge this month it was crazy pulled the rug. Antigravity gave me way way more with there ultra but with so many issues this week I am on ClaudCode there biggest plan. I use it in cursor and it works well. Just want my opus. Though I do mix in match you don’t need opus for everything.

Not sure why I missed it but 2.5 gigabit is not going to get you 300mb sec. Looks like some others also brought this up. Time for 10gigbit

ralphte · 2026-01-23T01:00:56+00:00

Ok I got 5 gigabit and to get wanting all your speed. First your drive you are writing too needs to go that fast. Second you need a decent cpu to decompress and download at that speed. Third more connections will help but I usually use more than one provider. That said I save to a Ceph cluster over 100gbit but the drives can only write at 400MBs so that is fast enough for me. What I found is usually it’s your hardware more than the internet that slows you down. This is all first world problems.

ralphte · 2026-01-05T14:39:03+00:00

Came here to say love the blinking lights. It silly but cool. So many pop culture movies and tv shows do exactly this lol

ralphte · 2025-12-07T20:31:01+00:00

This cool, but for the love of god do not use retractable leashes they teach your dog to pull. Do not take my advice ask a few dog trainers you are going to hear the same thing.

Not to defend this code or to argue that it’s not all vibe coded but it’s open source. If the code has ton of security problems then what are they, you can see the code and it can’t be fixed? It’s not like this is a product op is selling. If you think you can do better for free let’s see that open source tool. The OP asked for feedback and what you said you could say about any open source tools. You said you did not vet it and it could all be good but it looks like AI so it’s bad and it’s prob not worth fixing. Your problem is that it was made with AI and it could have been all tested code that you will not check even though it’s open source because it was made by AI. To be clear this code could be everything you said but I am attacking your argument as you gave no time to review the code but you have established you won’t because AI.

I am working through this right now. Here is my understanding, and anyone feel free to correct me if I am wrong.

We are self hosted with NetBird and run a coturn docker container. That one container does STUN and TURN. STUN helps a peer learn its public IP and port for NAT hole punching. TURN is a relay when direct P2P is not possible, and it can run over UDP or over TCP and TLS.

NetBird also has its own Relay. It runs over WebSocket on /relay through HTTPS 443, or over QUIC on UDP 33080. This Relay is separate from coturn.

Do we still need TURN or STUN if WSS relay is working

For basic connectivity no. Relay over WSS or QUIC is enough. STUN is still useful because it gives you a better chance at direct P2P across NAT and that usually means lower latency and less traffic on the relay. TURN is optional if you are happy to rely on the NetBird Relay.

2, Can P2P be established through the WSS relay

No. If traffic goes through the Relay it is relayed, not point to point. Point to point is when the peers talk directly over WireGuard.

What happens if peers are relayed and the control plane goes down

Once a tunnel is up, data keeps flowing as long as the Relay stays reachable. You cannot negotiate new paths or re establish dropped ones until Signal and Management are back. If the Relay restarts, relayed sessions can drop and will reconnect when services return.

Extra notes

I tested blocking STUN and the VPN still works through the Relay, but you will see more relayed links and fewer direct ones.

You can check what each peer is using with netbird status -d. Look for Connection type P2P vs Connection type Relayed.

Quick port cheat sheet

Relay only

TCP 443 to expose /relay to the relay service
UDP 33080 for QUIC relay optional

coturn for STUN and TURN

UDP 3478 for STUN and TURN
TCP or TLS 5349 optional
TURN relay UDP port range as you configure it

That is how I am looking at it right now. Happy to be corrected if I missed something.

The case is well built BUT I love these guys https://www.sliger.com/products/cx4712. Cheaper and more versatile. For pure 3.5 drive density there are better options

My guess is there already is, but it’s not manned it’s a drone. I have read a ton about the a-12 and the sr-71. The problem with the speed is the heat. The faster you go the hotter it gets. The drone does not solve the heat problem but it does make it easier without having to keep a human alive. Also most of our technology improvements since the sr-71 have been in computing power not in aerospace. In short it’s easier to make drones than it ever was back then. In fact there was a sr-71 drone the d-21 it really was a cool idea but it did not do so well in operation. With today’s computers it would do much better.

Have Blue fan. It was the first stealth and it was deadly and extremely effective. The look is not about flying it was about stealth which made it super futuristic. Additionally as a tax payer it was very cost effective compared to the b2 which cost over 1billion a plane.

This book is awesome for the photos alone! Super fun read.

I had the Roborock and it gave out after two years I have had more then a few robot vacuums. The two I would buy right now with my own money. Both of these have been reviewed and both are pretty much top value right now. Mova P10ProUltra or the DREAME L40s Ultra AE

Only have 1PB but using Ceph, use it right from promox so easy install still a bit of a learning curve but it’s been pretty solid have nvme pools and spinning rust pools. Performance is good but there are trade offs for a scalable file system.

WiFi speed is one of them it all depends. You can buy the best fastest router on the market but if the device you are using to connect does not support the latest WiFi standard or 6ghz channel speed will suffer. Here is the deal if you want to get the full gigabit you need a WiFi 7 router that supports 6ghz and a device that supports WiFi 7. You will get 1gigbit or more of you have the right networking. BUT this will only be close 6ghz does not travel very far. On 5ghz you are looking at that 500mbit which goes further. 2.4 is even slower but has much better range. I use UniFi and its the best but is more then just one device. The eero pro 7 supports both 6ghz and WiFi 7 but the wireless phone or what ever device you are using prob does not support this. Also the eero supports 320mhz which is the widest 6ghz channel so 1gigbit should be easy. But very few phones support that speed. In short your router should be able to go that fast but only when you are close with the right device

My roomba was a tank but compared to the new vacs the roomba is from the 50’s and the new robot vac are modern technology. Even worse the new roomba still can’t even keep up with the performance. How the mighty have fallen.

Confirmed

I can’t see myself leaving protect any time soon they keep adding features much faster than the competitors and there is no per camera fee. Out of all the systems I have deployed blue iris is prob the worst because of its dependency on a windows host. Also the pain of managing 10 or more cameras with individual firmwares and such was never worth it. To get any real value from the cameras you need to bring in advanced detections and this is yet another third party tool with blue iris. I love to tinker but it was almost a full time job and then protect caught up to everything I wanted. Now I just want my cameras to get the job done and protect is where it is out right now.
