Thank you! I think the circular property of that matrix is the key.

I think what did it for me is to recognize that the last column has characters that, for each row, come before the characters in the first column (since they are rotations). So we can view the last column as coming "before" the first one.

1. We sorted the first column to get the BWT column. Thereby we created the structure where the BWT column comes before the sorted column.

2. Therefore if we insert the BWT column before a sorted column, the order of row elements is preserved

3. If we now sort again, the order of characters across individual rows is again preserved

4. Going to step 2 again preserves row order

5. Once all columns are populated, therefore all rows are in the correct original order. And thanks to the end marker we can get the original string from any row.

The unintuitive part of BWT to me was always the reverse operation, which was the only thing the post didn't give intuition for :-)

I know right? It sure makes you wonder.

Yeah, pesky technology disconnecting us. Best to go back before cars where nobody could move anywhere. See you Sunday in church

This will be a bunch of rushed garbage. It will be like Java applets

Alan Ford is another Italian gem taking place in the states and touching upon social justice issues, though more of a cynical/dark comedy. One of the villains is SuperHic, a drunk who steals from the poor and gives to the rich

Bet you wouldn't be this high and mighty had ICE invaded your town and pulled every resident including your family out of their bed at 3am at gunpoint because "they had credible evidence there was an illegal in one of the houses"

You don't need a Tesla to figure this out, my toy RC monster truck does the same thing.

Not to put too fine a point on it but how much of this is due to a homogeneous census?

I love the mountainous look of that region. It reminds me of the Guyun Stone Forest in Genshin Impact.

I'm also loving projects like these [1] popping up all over the place. Looks like they are installing Tesla Megapacks with LFP cells. [2]

I got to briefly try a N900 back in the day. When it powered on you would briefly see the raw X background stipple and the x-shaped cursor before the window manager loaded. I liked the nerd factor of it but I knew at that point the company was in the weeds.

I have a teen who's been using DuoLingo for French for a while but hit a ceiling with spoken language. I suggested to him to look around for voice chats with French speakers like maybe on Discord but it's a desert out there. Wonder if you have some experience with using these paid options to recommend. Would be neat if there could be something without a rigid course-like structure he could join occasionally for low-key conversation practice.

> * heavily salt your water, but it does not need to be "salty like the ocean"

Speaking of, wonder if using seawater for cooking would have good results. Pasta or otherwise!

That's funny, pretty sure we used Standard ML on the old oscilloscope Macs in undergrad. Not Apple 2 of course, but still already pretty dated even at that time (late 90s).

> I think "people want frictionless ways to purchase products" is a PM pipe dream more than a description of reality.

I get what example you are referring to, but there are degrees here. For example the Buy Now flow really is handy; and I find I favor merchants that let me pay by scanning some kinda QR code from Apple Pay or Venmo. I definitely don't miss the friction of having to go dig out my credit card, mistype the cc#, type the wrong cvc if Amex, repeat the purchase after getting declined once and responding to a fraud text, etc.

My pet theory is that stupidly powerful rare-earth magnets, and class D amplifiers are the two main things that killed "hifi" type audio. No more black magic needed messing with transistors and op-amps on bespoke circuit boards that used to be the moat for these oldschool brands.

My Alexa Echo Dot 4 sounds better than my home audio setup from the 90s. Now, a fair comparison would be to a modern floor speaker with modern magnets and amps, but I'm too old for this :-)

I guess to add to that, what if there is another party involved with your work that will demand latex? Like a library or journal publishing your thesis/paper?

The primary feeling I get from using LaTeX is: fear. Any little special thing I adjust tends to break the document, or move figures, or fixing one thing breaks another and so on. And forget about changing templates.

In the couple of instances I experienced this, the problem is that the system is like the proverbial elephant that a bunch of blind people are familiar with through touching the parts they are next to; but the complexity is in the relationships in-between.

There needs to be a person who will take charge and learn/document the whole system, except people who work on it are overloaded and too exhausted to take this on. And management doesn't necessarily have the insight or incentive to make this happen. It's an interesting phenomenon.

There were some other brands that tried it but the airflow is much weaker and has ozone problems. Maybe Ionic Breeze? It was a Sharper Image type product.

The Dysons do have regular bladed impellers in the base, but by expelling the air in a ring shape take advantage of viscosity to pull air around the ring for an added flow.

My main reason for preferring the Dyson type fan is the noise they make is a soothing white noise, instead of the helicopter-like beating noise the box fans make.

I'd go further and even say per second! Actually PG can still handle it, the main problem is that it has a more complex runtime that can spike. Backups? Background jobs doing heavy writes? Replication? Vacuum? Can tend to cause multisecond slowdowns which may be undesirable depending on your SLA. But otherwise it would be fine.

In Soviet Russia government protects harmful contents from us!

Do you know if some of these systems have components to periodically checksum the data at rest?

I'm just salivating at the thought of being on the telco side with access to all the base stations and writing various visualizations/analysis to find hotspots like these, bet it's a lot of fun. :-)

I'm old now, but thanks to LLMs I can now again tinker with things I don't understand :-)

This is fascinating.
