One Rails app self deployed in VPS can really go a long way.

I'd add:

- Learn tailscale. It's one of those technologies that takes half a day to get used to (claude code will answer all your questions), and you'll never want to live without it in the future. SSH into your VPS, install tailscale and use `tailscale set --ssh`, and shut down `systemctl stop ssh.service`. You don't even have SSH daemon runing anymore, extra safety.

- Use a simple docker compose to run your dependencies like docker. Bind to the tailscale IP, so ports: {{ tailscale_ip_of_this_server}}:5432:5432. This way your database is not exposed to the web, but it's exposed to the tailscale. Use tailscale_ip_of_this_server in your ENV vars to rails to connect - since it's running in the same server, tailscale will route it to localhost (and with localhost latency).

- With claude, set up a second VPS, add it to the same tailscale, turn of SSHD. They can now connect directly via tailscale (try ping or sshing between them).

- Then, install claude code on this second VPS. Since postgres is bound to the tailscale IP on the main, the 'slave' can connect to it. Install postgres via docker, but have claude set up a 'streaming replication' between server MASTER and server SLAVE, using tailscale ip.

100% secure, encrypted, and now you have a postgres replication with zero data loss if something goes wrong.

In the same SLAVE, you can also install barman - claude code will help you set it up.

You then have a postgres BACKUP with point in time recovery.

There you go!

How do you reach your server without SSH in the event Tailscale is down or your Tailscale account has a problem?

And none of them can hold a candle to QnX. I've used a whole raft of them and QnX stands heads and shoulders above the competition. The consistency of the implementation is extremely impressive.

I would like to hear more about your experiences. What makes QNX better than others?

Remember when they shafted the free plan, laid off some good people and redesigned their website to look like some garish notepad? Pepperidge Farm remembers...

I was running about 1000 machines on VMware in my previous career. It was always a love/hate relationship with them. We were able to achieve a lot of our goals using VMware and it was hard not to be ecstatic about the results. At the same time, they were always a nightmare to deal with, the software was buggy and support wasn't great.

I always dreaded renewal time because it was normal for them to use it as an opportunity to extort us. Microsoft was a breeze in comparison. It's funny because Microsoft always had such a horrible reputation. I don't know if I was just so abused by VMware or what, but Microsoft was just easy. We had an annual true-up date and we always knew where we stood with them. We reported our numbers and that was it. No surprises ever and there was never an issue if we didn't report any growth. VMware was always pulling some kind of shit and was absolutely determined to push us over budget every time.

Did you switch from VMWare to Microsoft?

The first mobile phone, the Motorola DynaTAC 8000X, was launched in 1984 for $3,995 (more than $12k in 2025 dollars). So we should expect a 12x cost reduction in LLMs over 40 years.

IBM 3380 Model K introduced in 1987, has 7.5 GB of storage and costed about $160000 to $170000, or adjusted for inflation it is $455000 in 2025 US dollars, that's $60666/GB. A Solidigm D5-P5336 drive that can store 128 TB costs about $16500 in 2025 US dollars, that is $0.129/GB. That's a 470279x price reduction in slightly less than 40 years. So what is likely going to happen to LLM pricing? No one knows and both your example as well as mine doesn't mean anything.

+1 - I work in finance, and there's no way we're sending our data and code outside the organization. We have our own H100s.
undefuser · 7 months ago
Does it mean that renting a Bare metal server with H100s is also out of question for your org?

I think it is very intuitive that more space beats the pants off of more time.

In time O(n) you can use O(n) cells on a tape, but there are O(2^n) possible configurations of symbols on a tape of length n (for an alphabet with 2 symbols), so you can do so much more with n space than with n time.

I think it really depends on the task at hand, and not that intuitive. At some point accessing the memory might be slower than repeating the computation, especially when the storage is slow.

Yeah, I use LODs already but as you say, even my lowest lod far away is too many vertices. Imposter rendering seems very interesting but also completely bonkers (viewing angle, lighting)!

have you considered using meshlets technique like Unreal Engine Nanite or Assassin's Creed? It could potentially open the door for better culling and more effective depth prepass.

I work for IPinfo. Thank you for raising a great point.

Integrations and maintenance were major issues when it came to users using the IP database. Usage of our IP database in software and platforms where data download facilities, maintainability (updating the database at regular intervals), and using an MMDB reader library were issues that were stopping us from universal adoption. For example, search/SIEM/threat intel platforms, distributed systems, firewall applications etc.

So, we just decided to launch an API to complement our data downloads. It is easier to use, and the unlimited requests make it a strong candidate.

We are rebuilding our backend in Rust and also developing a bulk enrichment API endpoint. The intention of the API system is to replicate the performance and features you get from a local database, with ease of use and minimal friction. Of course, the API is competing against the local database and will never be perfect, but I have to admit that using the IP database, particularly the binary database, and maintaining it is not as easy as using an API service.

How often does a given IP address changes to another country?
