ipunchghosts··on Ask HN: What are you working on? (September 2026)
Software to promote live music and drink specials so I don't have to check dozens of Instagram accounts to find out what's happening tonight.

I wrote my own site parsing toolkit which removed the friction I have with the current ones. It's now easy to add new locations quickly to scale.

ipunchghosts··on Universality of Gradient Descent Neural Network Training
An adjacent question: is there an input dataset you can use for training that be computed in closed form so that when you train on your target dataset, learning is effecient.

Methods like formula driven supervised learning exist to arrive a good pretrained weight state, but could this procedure be generalized for specific datasets or flavors of input data.

ipunchghosts··on Ask HN: Who is hiring? (August 2026)
I met Pete when I worked at kitware. Would u have time for a fifteen min call? I'm interested in the position but have questions about viabikity given that capabilitiea of ai. Send an email.

sorry, for some reason i was never notified that anyone replied.

I have work in synthetic aperture sonar for detection of these mines for almost two decades and can answer questions about this area for HN.
ipunchghosts··on How My Images Are Dithered
Eero simmoncellis group showed that specific network modifications allow the networks to extrapolate beyond noise they were trained in.

NNs can certainly learn beyond what they were trained for as new architectures have demonstrated. See benchmarks for any if the dan hendryks imagenet corruption dataset benchmarks (imagenet c r and a). Data + architecture work together to enable.

I have work using neural networks trained on synthetic aperture sonar SAS imagery using language only. The SAS datsets are extremely hard to come by. The dataset I used was from parts if world I can assure you we're never in the training set. My approach exceeds what clip models can do zero shot wise. Therefore, the network classified imagery if a modality and environment 100 percent not guaranteed to be in the training data.

ipunchghosts··on How My Images Are Dithered
This is a good way to think.
ipunchghosts··on How My Images Are Dithered
There are many features in an image dataset which a can correctly classify the dataset. Neural nets usually focus in texture which we human clearly don't, we focus on a higher level abstraction and usually ignore texture. Using either would encourage the network to use broader features and ignore texture
ipunchghosts··on How My Images Are Dithered
I am not sure that's true. It would learn to not focus in texture which is what current nns do.
ipunchghosts··on How My Images Are Dithered
Why is this not a typical data augmentation method for training deep networks? It would allow the networks to learn invariants that's align with humans. Currently, I suppose none of these dithered images would be correctly classified.
ipunchghosts··on I Tried Building a Real App with AI. It Took a Year
The authors experience is not mine. I have an app/website combo deployed that is getting 60+ visitors a day and the app is getting downloaded weekly. Both are growing. All "vibe" coded.

Now I have 20 YOE in software too before the booon of AI.

This is missing castles. There are several in and near lerici Italy not listed
ipunchghosts··on Ask HN: Are the heaviest AI users of your team blowing past everyone else?
Yes. I can tell who uses it and who doesn't. Also who is good at using it and who isn't.
ipunchghosts··on Ask HN: What are you working on? (June 2026)
Synthetic aperture simulator. I could never get finding to build so decided to do it myself.

ipunchghosts··on Ask HN: What are tools you have made for yourself since the advent of AI?
I built a synthetic aperture sonar / radar simulation engine so I could generate endless amounts of procedural generated scenes to train a world model. Data for sonar is especially hard to come by.

I think ppl only care about how Claude or codex does.
ipunchghosts··on Ask HN: What are you working on? (May 2026)
I am writing synthetic aperture sonar/radar simulator and image formation code from scratch.

https://www.linkedin.com/search/results/all/?keywords=%23ape...

Too many codes or old or gate kept behind proprietary walls. Many are old and don't use the newest acceleration techniquea to make the simulation fast. Additionally, none of them scale using aws. I want SAS/SAR image to be easy to generate for anyone.

I have a similar finding for a website I made that collates college town bar specials and live music. Using agents with vision models works but it's not as straightforward as one would initially think. U can check out the results here. https://www.nittanynights.com

ipunchghosts··on Dario Amodei calls OpenAI’s messaging around military deal ‘straight up lies’
> but there's a massive financial reality here.

Not a chance. The DoD has massive pockers which and INCREDIBLY SPREAD OUT. You can't underestimate how spread this money is. The DoD has maybe a 64 GPU cluster and ALMOST NO ONE USES IT FOR DEEP MODEL TRAINING. Even contractors end up working with DGX boxes to do all their training.

As of 2023, I was doing the largest Deep learning training runs out of anyone I have known in the industry and I've been in the industry for 20 yeras. The second best groups behind mine were using 4 GPU locally machines that they had to purchase on contract.

There's no way the DoD can train these models themselves, not even close. They are COMPLETELY DEPENDENT ON INDUSTRY. I was the PM for a DARPA program in 2023 and SAME PROBLEM. They had no compute or would rely on university compute if a program had a university partner. YOU HAVE NO IDEA HOW FAR BEHIND THE DOD IS IN THIS SPACE.

ipunchghosts··on 30 Years of ReactOS
I would think claude code would help make a quick dent in boosting reactos capabilities. Curious what others think.
ipunchghosts··on Ask HN: How can I get better at using AI for programming?
Ask people to do things for you. Then you will learn how to work with something/someone who has faults but can overall be useful if you know how to view the interaction.
ipunchghosts··on François Chollet: The Arc Prize and How We Get to AGI [video]
I agree strongly with this take but find it hard to convince others of it. Instead, people keep thinking there is a magic bullet to discover resulting in a lot of wasted resources and money.
