Gemini 3.0 Pro is bad model for its class. I really hope 3.1 is a leap forward.

Just posted today another funny one that Opus 4.6 with extended thinking fails. Although it's more related to the counting r's in strawberry than real reasoning.

I pasted a piece of code with an error to o1-preview. MyTheprompt I pasted was fairly short and had nothing to do with Brooklyn or bike lanes. Strangely, o1-preview first "thinking" step was:

```

Brooklyn's new bike lanes

I’m focusing on Brooklyn transforming into a bike-friendly, pedestrian hub. This initiative aims to make the borough more accessible and vibrant. Council Members Lincoln Restler and Shahana Hanif are championing this transition.

Examining the error

I’m looking into the error message pointing to a tensor size mismatch in the forward method.

Identifying tensor size mismatch

I’m analyzing a tensor size mismatch in the forward pass of the ...

```

It did stay on topic after the second step. I am wondering why would something like this happen. Maybe the word "transformers"??

I don't share the full prompt has it's code from work. I'll see if I can reproduce this.

Same thing is happening in the greater Boston area. Many city centers have empty store fronts. Even some chains don't survive the high rent. Walgreens opened a huge space in the city center of Cambridge just across the street of a busy CVS. They closed it down about a year later. Just think how much money they wasted on this.

For me the biggest problem is the independent restaurants and coffee shops that cannot afford the high rent. They have to increase prices to survive. Most people are not willing to pay $4 for coffee or $12 for a sandwich. When you go to a coffee place you're not thinking about the rent the place is paying and if their prices are justifiable or not. Many people find cheaper places to go to. These places are usually run by people that either lucked out with landlords who didn't increase their rent for many years, or ones who own the property and are not affected by increasing rents.

Others mentioned banks that don't mind losing money because the physical presence helps their Online banking. I noticed this trend around where I live too. A new coffee shop was recently opened after the place was sitting empty for many months. The new place runs by a catering company. They probably don't mind if the place is losing money as long as it helps their catering business. It's a different way of doing marketing.

It seems they didn't learn from their mistakes. It sounds that the 2014 breach was caused by the same mistake.

"That gist is believed to have contained a login key used by a hacker to access an internal Uber database of 50,000 drivers."

New comment by yuvalmer in "The Disappearing American Grad Student"

yuvalmer — Sat, 04 Nov 2017 04:24:27 +0000

I didn't know about this quota, but it doesn't really matter. The main point, which the article didn't mention, is that being an undergrad international student is far more difficult. First, the high schools exams can be different and students might not be eligible to apply. Then there's tuition cost. How many Chinese and Indians can afford ~40K/year not including room and other expenses? Foreign students cannot apply for scholarship.

It makes much more sense to study almost for free in India/China/Finland/etc. and then do a GRE and apply to grad school in the US. PhD students don't need to pay tuition and even get a monthly stipend. Also many MS students get some sort of scholarship (but not all).

That's nonsense. It's only true for China (for obvious reasons). Amazon is more successful in India, UK, Germany, France, Japan, and the list goes on.

The interesting thing about WhatsApp is that most of my American friends haven't heard about it by the time it was acquired for $19B. One of the biggest success stories of a US based company that went global first.

Good luck to Brian on his next adventure.

Wouldn't it violate their promise that users cannot know who looked up their profile?
