It’s not that difficult, you’re just paying for “installation theatre” at that point, good for showing off on social media and getting some clout.

Samsung microLED required professional installation until a year or two ago. It’s essentially a mini-JumboTron made of individual panels. They’ve managed to reduce down to four panels on brackets.

Afaik, there is currently no "GPT-5 Pro". Did you mean o3-pro or o1-pro (via API)?

Currently, GPT-5 sits at $10/1M output tokens, o3-pro at $80, and o1-pro at a whopping $600: https://platform.openai.com/docs/pricing

Of course this is not indicative of actual performance or quality per $ spent, but according to my own testing, their performance does seem to scale in line with their cost.

GPT-5 Pro is only available on ChatGPT with a ChatGPT Pro subscription.

Supposedly it fires off multiple parallel thinking chains and then essentially debates with itself to net a final answer.

I must be crazy, because I clearly remember chatgpt 4 being downgraded before they released 4o, and I felt it was a worse model with a different label, I even choose the old chatgpt 4 when they would give me the option. I canceled my subscription around that time.

mastercheif · 12 days ago

Not crazy. 4o was a hallucination machine. 4o had better “vibes” and was really good at synthesizing information in useful ways, but GPT-4 Turbo was a bigger model with better world knowledge.

with web search, is knowledge cutoff really relevant anymore? Or is this more of a comment on how long it took them to do post-training?

mastercheif · 21 days ago

In my experience, web search often tanks the quality of the output.

I don't know if it's because of context clogging or that the model can't tell what's a high quality source from garbage.

I've defaulted to web search off and turn it on via the tools menu as needed.

FYI only one of your videos is displaying in HDR on your homepage, making the others seem dim in comparison.

It’s the Built for simple campus navigation video.

I’d recommend converting it to SDR.

I wonder if this is like dishwasher usage. As a kid growing up we never used the dishwasher. It was just the drying rack. The reason was you had to rinse off the big stuff anyways, and then the resulting quality of dishwashing was poor in it. You'd often get a fork with rice stuck between it still, which was unacceptable.

As a grown up now I use a dishwasher for everything that is permitted to go in it. I still have to rinse off plates first, and occasionally I do see rice between a fork that I have to then clean manually. But I'm not comfortable knowing that it won't clean as well as I could by hand, but it does a good enough job -- and in some ways a much better job (it uses much hotter water than I do by hand). I don't know if my mom could ever really be comfortable with it though.

You don’t need to pre-wash dishes before they go in the sink, beyond a basic scrapping of the plate into the garbage.

Pre-washing dishes degrades the performance of the dishwasher. This is due to the use of enzymes in modern detergent formulations.

I’ve sent dozens of people the Technology Connections video on this topic to rave reviews: https://youtu.be/jHP942Livy0

OK, this is getting interesting. I've done some tests.

First, some pictures [1].

The first picture is the front of the TV remote and what I presume is the window in front of the IR diode.

The second picture is what is supposedly the location of the IR sensor on the monitor.

The third picture is my hand attempting to block the IR emitter on the remote.

Here is what I've found.

1. If I block the emitter with my hand the remote has no trouble turning the TV on and off. Even if I've blocked it with my hand and am holding the remote behind the couch so there is no line of sight to the TV it still works.

2. It also still turns the monitor on and off, but the range is greatly reduced. I have to be within a meter of the monitor.

3. Blocking the receiver with a finger is similar, but the range reduction is more. I have to have the remote within maybe half a meter.

4. Blocking the remote with electrical tape has no effect on its effectiveness with the TV.

5. Blocking the remote with electrical tape almost completely prevents it from affecting the monitor. Maybe 1 in 20 times it will still turn the monitor on/off if near the monitor.

6. Blocking the receiver with electrical tape is similar.

7. Blocking the receiver by hand or electrical tape has no affect on the monitor's remote controlling the monitor.

8. The TV remote can turn the TV on and off and the monitor remote can turn the monitor on and off even if I go down the hall an into the bathroom and close the bathroom door so there is no chance that any IR signal is making it to the device.

9. The monitor remote does not turn the TV on/off even if held near the TV.

10. I also have an Amazon Fire Stick and its remote can turn the TV and monitor on and off. It uses IR for TV control functions (and RF for Fire Stick control).

11. As with the TV remote my hand fails to block the Fire Stick remote.

From this I think we can draw some conclusions but also some questions are raised.

• The TV remote can fully operate the TV using RF. The TV also responds to IR.

• The monitor remote can fully operate the monitor using RF. The monitor also responds to IR.

• The RF for each remote includes specific enough device identification that they do not operate the wrong device. The IR does not.

• IR is hard to block. Why doesn't my hand stop it? With the TV remote the window is big and curved so I could see some of it not being quite covered, but the Fire Stick remote has a smaller window that is much flatter. When pressed tightly into my palm it should be completely covered.

• Electrical tape almost seems to completely stop it, but I did still have an occasional signal get through.

• When turning the TV off from the couch I should be able to stop it from affecting the monitor by simply covering the window with my palm. Even though that apparently still leaks enough IR signal it reduces the effective range, which should be enough to stop it from affecting the monitor. It will still work with the TV via the RF signal.

I should have clarified: Samsung remotes always use IR for power commands.

They use RF/BT for all other commands, as long as the remote is paired to a TV.

Note: When the remote is not paired with a TV it will also send the basic commands over IR.

I've got a Samsung TV and a Samsung monitor in the same room. About 20% of the time when I use the TV remote from the couch to turn off the TV it also turns of the monitor.

If I'm at the computer and turn off the TV with the TV remote it turns off the monitor the majority of the time.

I wonder if Samsung will manage to make to so Denon and Marantz receivers will also sometimes turn off when you turn off a Samsung TV?

mastercheif · 4 months ago

This is because the remotes use IR for the power commands. There’s really no getting around it. A small piece of electrical tape over the IR window on the monitor will fix it.

mastercheif commented on Street address errors in Google Maps randomascii.wordpress.com... · Posted by u/brucedawson

I will give credit to the Google Maps team—they handle Queens NYC street address correctly.

Apple Maps drives me nuts—it will only return search results if you include the hyphen in the four digit street address ie: "36-08 33rd St" vs "3608 33rd St". Google will hit on either query.

The hyphen is a part of the "official" address. However, USPS has declared it unnecessary, there's no advantage to using it unless you're navigating by analog map, and it's a PITA to type on a mobile keyboard.

So if anyone on Apple Maps team is here: please fix this. I filled a apple.com/feedback ticket on this years ago.

For anyone interested in the peculiar history of Queens addresses—they convey a cross street and the number of the house ascending going northward.

For example: 36-08 33rd St means that the house is on 33rd St, between 35th and 36th ave, and is house #08 on the block.

That said, Apple Maps is far superior to Google Maps for transit directions, at least in NYC. Google's integration with the MTA is seriously lacking—their directions often do not reflect scheduled changes in routes, let alone real-time issues. That said, Google Maps is superior with POI search and address decoding.
