But for example if they used PMM squirrel cage motors etc, they would be nice and smooth, cheaper to build, more energy efficient.

On the battery front, using car-style or truck-style EV battery modules would be more robust and would reduce cost by somewhere in the order of 50%.

Instead, most trains still use induction motors (this is the high pitch whine you hear) and many train battery designs use industrial style rack mount batteries, with screw terminals, controlled by a massive PLC cabinet. In eMobility the controls are handled by a small safety-rated microcontroller.
They do. You're not being realistic. Almost everyone would like to have a choice between getting on a subway for super cheap or driving through traffic. You're saying they would rather have no choice between the two options? Come on.

The Bay area (people) want top of the line transit, all of California wants it. It's similar to how Ethiopia wants to get out of poverty. Both places can't get what they want for similar reasons: incapability.

Take a look at the high speed rail. Probably won't finish in both of our lifetimes. People want that thing, what's stopping it from happening is incompetence.
Great news! When I'm familiar with the project space+F works great, but isn't great for discovery.
Only newer currencies you could lock your money into a smart contract, or just stake it, such that you literally could not transfer your money for a year (or more). Lower liquidity but would de-fang ransom like this.

Alternatively, a smart contract could require large transfers to escrow for X months, and could have a secret poison pill such that it would abort after 30 days if you used a trap password.

Edit: Given the downvotes I guess people just wanted to snark? I interpreted this as a technical question but maybe I misread.

You say that as if companies are sane. Management may think you are valuable to them. But HR sets the salary bands. Management only has so much power over raises.
This shows another of the many ways in which a having a trusted third party involved in your finances is actually a good thing.

No, it's not that illegal aliens will actually vote. It's not a conspiracy as another poster put it. I have heard people like Chuck Rocha (democrat operative) talk about this on MSNBC before. It's not that they vote in the current election, it's that over a period of time if you do nothing to stop or deport them then you enact policies of amnesty and paths to citizenship or they have kids and over a 10-20 year period or so you hopefully get bulletproof majorities. This is not a conspiracy, I have heard democrats talk about this.

CBDC = Central Bank Digital Currency. Can we edit the title accordingly?
You've edited your post a bit from what I originally replied to. Looking at your bijection stuff, I think you're just restating Cantor's diagonalization with `(a_n + 1) % 10` as your mechanism for choosing digits, but maybe I've got that wrong. I appreciate that it's well defined, but I think it ignores my complaint.

Let's say I tell you that I'm building my list of numbers between zero and one by taking the natural numbers, reversing the digits, and just putting a decimal place in front:

0: 0.0....
1: 0.1....
2: 0.2....
...
10: 0.01...
11: 0.11...
12: 0.21...

It's a silly mapping, and I'm sure there are a few problems with it, but let's start there. For now it doesn't matter what digits I'll choose afterwards - maybe it's all zeros, maybe it repeats the digits, maybe I'll do something more clever, but skip that for now.

My list has a number that agrees with your number to any number of digits we choose. You and Cantor have to force me to give my infinite list of numbers all at once, and then build your infinite length counter example all at once. What axiom lets either of us do an infinite number of steps and say we're finished? What axiom says you can do an infinite number of steps after I do my infinite number of steps? When we do limits with deltas and epsilons, we say that we will get closer as we keep going, not that we got there.

If you give me the first 1000 digits of your counterexample, I can tell you all the elements in my set that match your number up to the first 1000 digits. If you give me 1001, I can tell you all the places that match that too. A million, a gazillion, I can keep matching. And as you keep adding more digits, I can keep telling you an infinite number of places that match.

So it really seems like there's a problem with the order of operations. It's like playing chess, and you force me to make all my moves and come afterward to checkmate me. But if we take turns, where I make a finite number of steps and you give me your next digit, then it's my turn again, I can keep matching you all day and all night.
Surely the relevant metric is population density?
They've significantly increased the timetable frequency though, so they're running more trains, and those trains are accelerating and running much faster than the old diesel-electrics. I don't think you're comparing like for like.
It is. A bunch of Bart stops now have developments around them, just look at MacArthur in Oakland with its 40 floor residential building next to Bart.
I think BART struggles with who it's meant to serve now, since it was clearly designed for ultra-peak weekday commute traffic. Recovery for weekend ridership is way better than weekday.

I also agree that the governance structure for BART is weird and overly complex. Why do I elect a BART director? Why are they in their own special BART districts completely discontinuous from the 10 other ways we have sliced up the Bay Area?

All that being said, BART has done some good stuff too. The new cars really are way better, and they were not easy to procure since BART has its own weird, non-standard rail gauge. They have increased frequency and shortened trains on weekends to respond to the ridership changes.

Most of all, BART remains the only form of Bay Area transit genuinely faster than driving in real-world circumstances: it averages above 60mph in parts of the east bay, and goes from downtown Oakland to downtown SF in 11min, which is often 2-3x faster than driving. It's the primary transit system that can compete head-to-head with driving. For that reason, I do hope they keep increasing frequency (shortening trains if necessary).
One of the soft skill tricks is building new allies out of subordinates. Almost nobody gets promoted to a level of influence until they’re a bus number in something important. And that often requires waiting for the project scope to grow enough horizontally for new domains to open up, or for someone senior to pass the torch.

If management is doing their jobs in growing the team then this all works out. But if they’re letting those with tenure get first pick of new problems, then you can play the game, carving out your share of the spoils, and then offloading other things before your head explodes. Every thing you offload is a ladder rung for someone else.

That way you end up with code that is no longer your baby but still not on the trash heap.
Electrification wasn't just an efficiency thing, it also made the service much better because of the faster acceleration - IIRC my travel time to SF on weekends went from 75 to 50 minutes, which opens up a lot of use cases.

There's something about Youtube ads that are particularly bad. Straight-up pyramid scams promising free money from Amazon or Elon Musk preying on the vulnerable, offensive videos, and so on. It's much worse than the ads I see in magazines, billboards, or on network television.

Had a Vick-20 as a kid but it did not do anything and I had no idea how to make it do anything or really any idea of what I wanted it to do. As much as I wanted to know more about computers there was no one in my (small rural) community in any position to offer any help or advice. In 8th grade my school got a bunch of computers (TRS-80s) and our first lesson was to copy the entire users manual out by hand before were could see a computer (I never saw a computer).

Anyway, as much trouble as the Internet is at time it is one of humanities greatest achievements.
Does California take any federal money? Do any of those plains states provide food to California. I don't think you would like this game as much as you think.
I run 90% of a communication stack on a 10 years old hp microserver gen8. I run a pretty vanilla rocky linux installation and run stuff that’s not available in repositories in unprivileged (rootless) podman containers. I mostly only serve myself.

Mail (postfix/dovecot) is cheap. Most other things i have nextcloud for (with acceptable performance). I ran a matrix server for a while but dropped it since none of my friends used that so it was essentially useless.

I can do most things without relying on big tech.

The expensive parts are:

- disks. I have four disks.

- time to learn stuff (it takes a while but some knowledge lasts pretty much forever)

- time for maintenance

Edit: leaving the big tech is really going DIY, learning how the individual things work and then plumbing them together. Anything other than that is largely snakeoil from what i’ve seen. Some friends tell me modern mid-high end NASes might do some of the things you like.
I have a significant amount of crypto and use a ledger wallet. Recently I noticed that the ledger app on my phone requires precise location access to function. It just hit me that ledger has precise locations and wallet balances of all its customers.

It's just a matter of time when this information falls in the hands of organized crime. I have since then moved to another wallet and am thinking of selling my house and moving. I have taken steps to ensure that none of the apps that have my crypto balance do not access my location (graphene os with location disabled and always on VPN etc.)

This news bothers me. Maybe the criminals asked for data access as well?
Anyone that get’s a telephone call from “Google” should be immediately suspicious. I used to work for a company that paid GCP about as much as my annual salary _every_ month, and we still struggled to get GCP on the phone when we needed assistance.
I did the same, learning basic along the way. I got a dot matrix printer and learned how to send print statements to the printer. I wrote an essay for school and printed it out line by line using print statements. Good times.
So…?

Even if all of your coworkers are flaky the majority of the time, that just seems like human nature.

Most people are mediocre or in that ballpark range.

Yeah. It was a big money grab from years back. Lots of controversy for sure. If I recall Amazon now owns .buy, etc.
They do. You're not being realistic. Almost everyone would like to have a choice between getting on a subway for super cheap or driving through traffic. You're saying they would rather have no choice between the two options? Come on

Sure, everyone wants an easy commute where the train picks them up in front of their house and drops them off at the office, but they also want their house with yard in Walnut Creek. Or lacking that, their single family house in the Sunset.

Sure some people would be happy in a high density city, but do enough people want it to make it worth building? As dense as downtown San Francisco is, it's still a long commute to the Easy Bay or Peninsula from the Sunset or Richmond. Driving is usually faster and more convenient.
Considering the bad transit options they get anti transit is the rational choice. Suburbs are dense enough for great transit but it is expensive and so nobody can afford to give it to them. Thus continuing the cycle of bad transit worth opposing as the waste of money it is.

So the article says, “[authorities] have also not confirmed whether any payment was made” and also says they’re looking for the kidnappers.

I’m gonna go out on a limb and say that ransom was paid and that’s how they were able to locate the Ballands.
Let's put aside that I would never trust reviews or ratings on most sites (like TripAdvisor) and imagine they are all trustworthy.

"OpenAI shows an example where they ask Operator to find the highest rated day tour in Rome on TripAdvisor, and then book it."

If only agents use TripAdvisor and the agents circumvent TA and purchase from the cheapest seller or straight from the supplier - who will write reviews and how would TA track sales or interest for ratings or popularity? Best case it would become a feedback loop run by the agents, worst case new data on TA would more or less stall. Without traffic or insights TA has no API to sell (unless someone wants stale and outdated data).

If AI would end the WWW it's going to be a hell of a lot more expensive for consumers to subscribe to AI than having to put up with ads or buying subscriptions to services or sites. I really can't envision how AI will function when it's hoovered up the web (and any data it can find) to then being at a point were little new data is available. Will we end up with $200 a month AI subscriptions that are based on data from a handful of data brokers? Would we trust those brokers? I certainly wouldn't celebrate AI as the only interface to information, especially since we would likely end up with fewer gatekeepers than we have today.

(Dead tired and hope my point comes across)
Has nothing to do with legal differences. It's just a different customer service team you end up talking to. It's in the same class of tricks as knowing the precise set of prompts to give to get immediately to a human operator when you call the main line.
My career isn't quite as long as his, but I concur with all the sentiments.

I will note that some of these are easier to say in hind-sight than do at the time.for example There's a lot of pressure on you in your early career to prioritize work over family.

I would add the following; if you have the choice, work at a place you like to go to, doing work you like to do, either people you can grow to work.

I know that's not practical advice for most, but if you are in such a place don't trade it away just for money or status.

And if you come across such an environment and are offered a spot the consider it carefully, even if it isn't the highest paying offer.
It has been great hasn't it?!? The difference between running every 30 minutes on weekends vs ever 2 hours is the difference between hopping on the train up to Redwood City for lunch with a friend and then back again. Versus one of us driving one way or the other.

If they can electrify the San Jose to Gilroy segment that will be even better.
If you have to cut red tape for certain projects, the tape probably shouldn't exist in the first place.

edit: for instance, if you have e.g. an environmental regulation that is so onerous that exemptions must be doled out for something as sensible as train electrification, then you don't have an environmental review regulation, you have a 'build nothing except what the exemptor decrees' regulation. Which is rather antithetical to the rule of law and good governance.
Jfc can we not allow headlines like this? Fucking disgusting.
There's no such thing as an F6 hurricane; there is also no such thing as a "Category 6" hurricane, which is the correct nomenclature. I wouldn't mention it except this seems like another one of these cases where we say "every storm is climate change" and I just don't think that helps the argument.

> Charcoal is just as goodias coal in general.

is an almost meaningless statement in the context of producing quality iron and steel.

"Charcoal" is a reasonably consistent product, "Coal" is an entire spectrum that ranges from [thermal coal] through to [metallurgical (coking) coal].

In a quality production pipeline there's a seperation between means of generating furnace heat (can be electric arc, can be thermal coal fired, can be charcoal) and a means of sourcing carbon for bonding with raw iron ores (coking coal).

In the context of low grade iron and poor steel manufacture the distinctions matter less.
What are you talking about? The noise you hear from trains is the wheels. Battery trains basically don't exist because of this cool invention called a wire and pantograph.
I’m not attacking it. I’m telling you how it works in BigTech companies. That’s also why I got the hell out of BigTech and prefer smaller companies - where I was between 1996-2020 and after 2023 and I’ve turned down opportunities to make a lot more money at larger companies.
Its one of those things that I will forever evangelize for, because the one time I was able to use it, I had my most productive year ever. My github activity graph for the 18 months I got to use zenhub looked like a beautiful green meadow.

I've tried most other project management software. They all stink in one way or another. JIRA is a known problem, ClickUp, Monday, and friends aren't much better. I never liked pivotal, and its dead now, so doesn't really matter. And Github's projects feature is just too spartan to be useful

There's a funny dynamic here I just came to appreciate. A perfect use case for AI is writing config file code (relatively simple stuff with lots of examples in the training data). Zed has replaced VSCode as my GUI editor, but I still use Neovim in the terminal. The "just works" aspect of Zed is nice, but I could see myself maybe opening my Neovim config with it one day to use the AI features to tune something up. Well, maybe I'd actually use Aider, but it's a fun thought anyway.

It makes me wonder if highly configurable software plus AI can be combined for an outcome that "just works" while also being highly personalized. One thing that kind of surprised me about Zed is that the AI assistant isn't very good, in my experience, at answering questions about how to configure Zed. Models have their cutoff date, of course, but this seems like low hanging fruit for some context injection based on keywords. An editor feature that can help me quickly implement my preference choice and get back to work without a visit to the docs would be truly adding value.
This sort of thing keeps getting written. You will still be able to art, even if AI art becomes better. I can still, to this day, still go for a walk even though cars exist. Not because I need to get somewhere, necessarily, but for the love of walking.

This is only being litigated in this way I think because art people never thought automation would come their way, and they're thinking about this stuff for the first time. A silly comment from some GenAI exec is not much justification for such an article. People know that writing and making music is fun. Said exec is just paid to say the opposite.

I grew up in Beverly. It's an Irish Catholic enclave. "Integrated" is not a word I would choose for it.

You're right to call out that previous commenter doesn't seem to know anything about Chicago neighborhoods; how else could you claim someone was "gentrifying" Beverly? But I wouldn't call out Beverly as a bastion of racial equity. My Black friends couldn't walk with me down the street after dark, in the 1990s, without us getting fucked with by passing cars. I doubt it's that much better now.

"Bronzeville-adjacent" is a very funny way of describing it; like saying Tacoma is Capitol Hill-adjacent.
This is a really weird attitude to work.

To see everyone around you as a predator.

You’re there to do work and be helpful to people. Do it if you can. If you can’t, explain why and don’t do it.

I can’t imagine someone who sees their colleagues as predators is much fun to work with. There’s going to lots of attitude and angst. Steer clear of employing this type of developer.
> No ticket or product manager is perfect

Getting a product manager to write technical tickets is generally a mistake, I would say.
Honestly, I think even the old Caltrain cars were pretty clean. The only dirty parts were the bathrooms (and honestly, train bathrooms are sort of gross most places). Caltrain has always been sort of luxury, though; the median Caltrain rider has a >100k household income, which come to think of it, might be one of the highest median rider incomes for a public transit system in the world.

The obvious explanation is that it's 2025 and the theme is "fuck you".
Do you care about optimizing your compensation? The author is telling you how to do it. I don’t. But I’m also 50 and did my bid in BigTech. This is good advice for early career folks or people who care about getting ahead.
The other important implication is how Caltrain could be routed through underground tunnels to Salesforce transit center. 4th and king isn't super nice and, correct me if I'm wrong, but it isn't well connected to other modes of transport. Maybe some muni buses.
The degree of ideological doublethink here is bizarre. As far as I can tell:

- Crypto is good

- Fiat currency is bad

- Except the US dollar, which is good

- So US-dollar backed stablecoins are also good

- But we can't have the Fed operate a stablecoin, that would be bad
