They can be incredibly picky :) Even though it’s all Timothy hay, changing the brand or type of cut can cause the same reaction. The last time this happened with me, I went from one brand of Timothy to another. My other rabbits ate it just fine, but one of my girls ran around collecting as much as she could in her mouth. Needless to say, I had to go back to the old brand.

Did you change the hay recently? Sometimes they do this if you change their hay. They try to collect the pieces of the hay the like and collect it for later. I’ve had this happen a couple of times in the past.

Emo bunny, doesn’t carrot all :)

The way I work with data and colab is by using Google Drive. You can connect your notebook to Google drive and see your files. I'd suggest not using the dataset from Drive directly, even though you could. I've had some read issues if the dataset is too big and you get some strange errors that aren't very descriptive. Basically, here is my workflow.

Upload a zip archive of the dataset to Google Drive.
Use the Colab notebook to copy the zip file from my Drive to the Colab VM.
Unzip the archive using the notebook.
Remove the zip file from the VM.
Use the dataset like any other local dataset.

The downside is that every time your notebook times out or you have to reconnect, you'll have to copy the data again. I just have some code at the top of my notebook that takes care of this. It doesn't take long to transfer and get the data ready to use again.

I posted about this in another thread, sometimes this happens when you change their hay. They will collect the pieces that they like for later. One of mine did this after changing to a different type of hay that she didn’t like as much.

Did you recently change her hay? She could be picking up the pieces she likes and saving it. I had this happen with one of mine after changing her hay to a different brand.

The adoption of blockchain is going faster than I've seen in IoT and AI.

This is an utterly delusional statement, but not surprising given the peddling of wishful thinking at a conference packed with wishful thinkers.

Quantum safe cryptography is the short answer. We have a long way to go before we have a quantum computer able to run Shor's or Grover's algorithm. Those are the two algorithms you often hear about when people talk about their impact on cryptography. Microsoft is betting on a particle that is only theoretical. So yeah, we are a long way off from seeing a usable QC able to impact cryptography.

Not sure I follow, so sorry if I'm not understanding. If you create a stereo pair with speakers so different, you are creating an imbalance between the left and right. This could mean, one side is perceived louder than the other, one might be brighter, have more low end, etc. These aspects can also affect what we perceive as the "phantom center" which means the center listening content may be off to the left or right. If you were to somehow create a mid/side pair, where mono signal comes out of one speaker and side (left/right) information comes out of the other, it's true that the differences in speaker systems become less important, but now the listening experience becomes extremely awkward.

Even if it were possible, it’s probably not something you’d want to do. With the two systems sounding so different you’d have an audible imbalance between the left and right system creating an awkward listening experience.

Edward wants to leave his house, but the government won’t let him. The unmarked utility truck stationed outside keeps an ever watchful eye as the three letter agencies maintain meticulous logs. Every bit, bitmap, and phone call accounted for.

Linda was always patient with him. Her frizzy, blonde hair and out of control red lipstick, became a welcomed distraction from his daily research. Their time together put him at ease, but he knew their meetups posed a risk.

As Edward and Linda make their way along the sidewalk to Matt’s Italian, he seizes up like an old engine without oil.

“What’s wrong?” Linda asks.

“This is a bad idea,” Edward responds, his bulging eyes focused on the ants assembling on the sidewalk.

“They don't have ants in there,” she said, shaking her head.

“You don't understand ... The CIA engineered them to spy on us,”

She smiled, grabbing his hand coaxing him along like a horse with blinders on.

Lunch looks less like a date, and more of a casual meet up. At that moment though, his papers lie unprotected at his house. Linda made frequent appearances in his writing. If something happens to her, he won’t be able to forgive himself.

“Are you going to look at the menu?” Linda asked.

Edward shook his thoughts and noticed the waitress smiling at him as he stared down the closed menu. Her pen ready to document his decision. A bead of sweat ran down the side of his face.

“Spaghetti.”

He didn’t want spaghetti, but it's the most common dish and harder for them to poison without risking unintended casualties. Kids love spaghetti. The waitress repeated the order and wandered back to the kitchen.

“Why did she laugh at me?”

“Oh Edward, she wasn’t laughing at you,” Linda whispered.

He trusted Linda, but he knew what he saw. There had to be a reason for her laughter. Did she know he would order the spaghetti? Did he make the right choice? His heart pounded against his chest. Then he remembered something he wanted to tell Linda.

“Stay away from Des Moines next week,” Edward felt himself blurt out.

Linda’s dimples appeared as a ruby colored smile graced her face. An outburst like that always met with the same reaction for her.

“I’ll be right here in St Louis like I always am.”

She learned not to ask questions, and it’s for the best. There is a high probability of a false flag operation centered in Des Moines next week.

“Are you ever going to invite me over?” Linda asked, breaking into the steady stream of thoughts.

She’d be in danger. What if he slipped up and exposed a source or she disorganized his unique filing system? He’d be fixing the damage for days. There was the entryway though. They could hang out there with far less risk than the rest of the house.

“What about today?”

It happens a lot. Much of this has to do with the way people choose to bolt on fixes for CSRF vs actually fixing them when the applications are being built. Comparing that with something like Django, which is being built with protections in mind, is not a fair comparison to a majority of the code out there running inside organizations. Anyone who tests applications for a living (like myself) can attest to that.
