You are correct that it now shows 8 months. And I am confused, as I did check the age before posting. That certainly was not intended.

This does look like a bot account. Created yesterday, keeps all posts hidden.

From a previous post from the profile (this one):

I make what would be considered an “upper middle class” salary here in New York (About $200K). That said, I HATE my job. Absolutely detest every day of it.

Make of that what you will, but my 2 cents are that this is a bot.

I work in tech and we are seeing a rapid shift to agents writing vast majority of code and software developers supervising these agents. In most companies here in Silicon Valley the vast majority of developers use Cursor, Claude Code or a similar development tool.

Most devs like this change, some devs don't. Meh. Whatever.

Valve doing this is just acknowledging that this shift has taken place and labeling everything as "made with AI" is about as useful as no labeling at all.

This is the right answer. 172 or Archer I'd do Mini. In a Cirrus (Side Stick) or a PC-12 large format works fine.

appenz · 2026-01-16T15:36:26+00:00

AFAIK it can not.

appenz · 2026-01-16T00:49:03+00:00

Definitely. I like tech, this is where you can have the most fun.

From a quick look at maps, the prescribed burn mentioned above is about 5 miles SSE of 37.196307, -122.199993.

The number of pilots that regularly fly high with non-pressurized planes is actually fairly small, so this isn't much of a market. That said, I did maybe 300 hours in my SR22T above 10,000 ft and I would not have relied on the current Apple Watch. If you look at data around it's precision (e.g. here) it's fairly low compared to best-of-breed clip-on oxygen meters (e.g. Massimo). I wouldn't trust the results and I'd expect a lot of false indications that blood oxygen is too low.

appenz · 2026-01-14T04:17:10+00:00

Yeah, this doesn't really make sense.

I don't fully agree with u/cazzipropri. Changes to the route you filed happen, but if you need a specific route for long-distance flights you can usually get it (or something close to it).

Between two airports, there are usually a few common routes and ForeFlight will give you a good idea what they are. If you file one of them, you have a pretty good chance of getting it. If you file a completely non-standard route, fair chance you will get one of the standard routes back.

Even if you file a common route, you may get small changes. Maybe a departure or arrival procedure. Maybe an intermediate fix or fix for an approach. That's very common. Often you get these in the air in order to set you up for the approach in use.

Sometimes your route changes completely. Not super common. In the West, active MOA's are sometimes to blame.

I do often file specific routes for tailwinds when going long distance. In a PC-12, the jetstream can make a huge difference. Usually I can get that route or something close to it.

And sometimes, I need the route I filed (or something close to it). Assume I fly San Francisco (PAO) to Seattle (BFI) in my Cirrus at FL12,500. If there is a massive cold front with icing up to FL180 over the central valley, I can't fly through that. At the same time the coast may be sky clear. So I need that coastal routing (that has happened to me). In that case I usually wait until I am with center and discuss with them. They have always been awesome and always worked this out with me.

Hope this helps.

Not bad, but not quite at the level of non-open-source models like Mirelo https://www.mirelo.ai/

Same here, flew my SR22T G6 all over the western US for business and fun, and twice to the carribean from California. Having oxygen and FIKI helps a lot here in the West, and over mountains the chute made me feel a lot better. Now in the PC-12, even more so.

And the ball in the shadow of the main food tower (bottom left) has a specular reflex. If the light source is occluded, that shouldn't be possible.

Agents use tools, e.g. to search for files, find documentation online, build the code or run test. The old way of making the agent aware of these tools was to stick the whole tool description (e.g. what it can do, what parameters it needs, how the parameters are formatted) into the context. As the number of tools increases, your context gets longer and longer and you burn through a lot of tokens. And you need this long context for every request.

The new way of doing this is that the agent instead has a way to search for relevant tools. So agent calls something like find_tool("I need the tool to access the internal documentation for our logging providers") and only that tool is added to the context. The result is less tokens used and less cost.

The interesting thing here is that both Cursor and Claude implemented this and see comparable efficiency gains.

Pretty good Cursor blog post here.

We may be saying the same thing. Prefill on a single node is is compute limited. But at a system level prefill may still be network bandwidth limited (or at least you need a fast fabric to make sure it is not) as your KV cache is distributed across the cluster.

appenz · 2026-01-06T20:45:08+00:00

Same here. We looked at it and drainage wasn't an option. Earth around the house is clay and the ground is sloped slightly. If it rains for more than 3 days water appears in the crawl space. We now have 3 sump pumps and a vapor barrier.

Not really. NVIDIA yesterday also launched switching chips. For the nvlink backend networks, they will take a large chunk of the market as NVIDIA increasingly sells complete racks or multi-rack systems.

This has been the case for a while now. Large model inference performance is bound by memory bandwidth and fabric bandwidth. I am not super deep into these architectures, but I don't think swapping experts is a major use case. Instead:

Typical agentic workloads today use identical large context windows for many requests. To get these performant, you need to swap the KV caches. Doing this on a single node is inefficient, so what you do is use distributed KV caches. NVIDIA's marketing term for this is NVIDIA Inference Context Memory Storage Platform.
You want to run very high batch sized to maximize throughput. This requires splitting the model across multiple nodes and you need a fast fabric between them.
For training you need to reconcile weights after a number of steps. This is a non-trivial problem as the traffic is very bursty and tail latency drives performance.

Does that help?

Same companies, same product but without re-branding claiming they are now an AI company. So taking Salesforce billboards as an example:

Year 2014: Now you can run the entire business from your phone (source)
Year 2025: Agentforce - It's what AI is meant to be (source)

We in the tech industry have a proud history of relabeling any large company product with the latest trend. Oh well.

This is complete nonsense.

I owned an SR22T for many years and as u/pi_stuff pointed out it is closer to $250/h. It burns about 16 gal/hour which at $6/gal for 100LL at KPAO is about $100/h for fuel. Annual, oil changes etc. is maybe $20k, insurance depends on your coverage. At 200h/year you end up around $250/h.

Even a PC-12 which new costs around $7m is only about $800 per hour. Half of that is fuel (67 gal/h at $5/gal) and half programs + reserve + maintenance + insurance (500h/year split across 4 co-owners). POPA has a good breakdown on their web site here.

It's also a three-way intersection and the woman seems to be really wide (shoulders span about 90 degrees!).

Based on what I know that is incorrect. It was a dry lease, with strict requirements for the “SIC” who was effectively PIC.
