> The MTA does not have a good track record of timely maintenance

A big part of that is because the MTA has been starved of funding for fifteen years now, to the point where they've had to substitute capital funds for operating funds in an effort to keep the lights on. Maintenance becomes more expensive when it's perpetually deferred - and it just became even more expensive because Hochul's inexplicable last-minute flop in June caused S&P to downgrade the MTA's credit rating, which means all future bonded capital projects will have to waste even more money on higher interest payments.

> (ie: like their original proposal for a 15 month closure of the L line).

That closure was intended to fix damage caused by Hurricane Sandy, and to bolster the tunnels against future climate disasters. The decision to forego the full maintenance (made unilaterally by then-Governor Cuomo as a political move) just kicked the can down the road.

I have been doing some experiments with Agents, Reinforcement Learnings playing a 4x4 Tic Tac Toe game.[1]. Given my analysis of the "thought" process we are still really far from true understanding of such games. While in my game as well as OP"s, the rules are pre-trained and the models are good enough to reach a conclusion (which in itself is already impressive), it is still a long way.

I hope you realize what a god complex you had at the time thinking you had the right to harm others just because they were doing the same. This code of ethics is the source of hate in the world. I guarantee these people didn’t learn their lesson but instead started doing the same thing to others even less powerful than themself.
Generally, trains are scheduled so that one train decelerating roughly coincide with another accelerating. You can plan ahead and orchestrate all you want and overcommit capacity as much as you want. Leftover that didn't cancel out is fed back to hydroelectric dams for gravity storage which do require cleaning but are immune to chemical degradation.

By the way, implementing regen on synchronous motors is relatively easy, IIUC, command a positive torque to the inverter and it draws current and line voltage gets pulled down. Command negative and opposite happens.

A small weakness in this test is that one of the keys to strategic Codenames play is understanding your partner. You're not just trying to connect the words, you're trying to connect them in a way that will be obvious to your partner. As a computing analogy: you're trying to serialize a few cards in a way that will be deserializable by the other player.

This test pairs o1 with itself, which means the serializer is the deserializer. So while it's impressive that it can link 4 words, most humans could also easily link 4 with as much stretching! We just don't tend to because we can't guarantee that the other human will make the same connections we did.
The main issue with everyone agreeing is the one who disagrees often gains the advantage, especially if the control something they perceived more valuable then they are getting from being agreeable.

Could be a bottleneck some ways. In other ways its an accelerant (think space race).

Like most things in nature you probably get the most out of "progress" (kind of a slippery word in itself) through some type of equilibrium rather than an absolute everyone must work together.
There is no way to make this idea work, or for that matter describe any plausible way to impliment it.

VS, distributed solar, wind, water, geothermal, power that serves local grids, just fine. Battery storage will get much cheaper, and the generating

The world grid will have to wait until we have some kind of fusion power and a super conducting grid, where power is in fact too cheap to meter and has demonstrably less impact than any other source.
True, I didn't think of that. However, the root cause here perhaps is fat binaries? My preferred development flow consists of many small self-contained dynamically linked libraries that executables link to. Then you only have to relink changed libraries and not executables that depend on them.

AlphaSharpe: LLM-Driven "Discovery" of Robust Risk-Adjusted Metrics
While widely used by the industry for over a half-century, the Sharpe ratio falls short in out-of-sample robustness for portfolio judgments that generalize to the future. Despite many attempts to improve it—like the Probabilistic Sharpe Ratio—the problem persists. With their implicit domain knowledge and code-generation capabilities, LLMs are proving powerful tools for evolving algorithms and formulas. From enhancing matrix algorithms to making scientific discoveries, their potential is immense. It turns out that LLMs can discover new risk-adjusted metrics with over 3x the rank correlation to future Sharpe ratios compared to the Sharpe itself. When these metrics are used to select the top 25% of assets, they double the risk-return performance of the Sharpe portfolio. The paper dives deeper into this breakthrough, and the discovered metrics are available in the repository for full reproducibility. This research can disrupt how we evaluate backtests, select assets, or optimize portfolios!
It would make much more sense for it to be unified with the MTA subway, with more connectivity. My dream would be a single seat ride from Newark Airport to Atlantic Terminal in Brooklyn, via Newark Penn Station and World Trade Center.

There was also once a proposal to have the 7 train go out to Seacaucus Junction, which would be huge for accessing the East Side for NJers.
That's a separate issue versus trains going to/from NYC. They do.
For my mom‘s small business, I actually tried to craft something compliant by hand (because I can). It’s surprisingly hard to get it right! Like, don’t load external scripts unless consent has been given, reflect that in the interface, and allow to withdraw consent. For example, there’s a maps embed showing the store address. But that’s can only be displayed if you actually consent to the prompt! So that means you’ll need to hold a list of script sources to add to the document head if the respective category has been accepted, but not earlier.
Most implementations get this wrong, loading third-party scripts and snippets in normal script tags, assuming the users will consent anyway.
I really like the term "happy accident"; it perfectly encapsulates the uniquely human blend of spontaneity, creativity, and adaptability that even the most advanced AI struggles to replicate.
It's kind of disconcerting to see the "black establishment" (aldermen, churches, etc.) on board with this. Do they really think this is a good idea? Is it that they received enough donations to make them think so?
I agree. But performance can't be ignored, and for some systems like those I mentioned it's not distinct from correctness. Performance doesn't always mean "as fast as possible", e.g. for systems dealing with secret data it means "without leaking information via side channels", for something like petting a window watchdog it means "slow enough not to pet before the window opens, fast enough not to pet after the window closes".
Images and videos, though to be fair, the limit for both is 15 MB.

No, it just means that they spend most of their time waiting around for database and network queries to finish.

I wonder if the real limit is tunnels. Connectivity doesn't fix the issue of physical limits on tunnel capacity and the massive cost of new tunnels.

> Nothing great in the world has ever been accomplished without passion.

This is a great one that I’ve really taken this to heart this last year. It’s become fashionable in recent years to think that habit building, discipline and ‘systems’ are the key to success, but I’ve been finding more and more that passion and intrinsic motivation are far more powerful. This is unfortunately unmarketable though since you generally either have intrinsic motivation for a specific thing or you don’t.

But how are you writing generic code then? C preprocessor macros? Abstract classes? No genericity at all?

C preprocessor macros are a hack, they are useful, but they come with plenty of issues. If you are using macros, there is a good chance there is a superior solution that uses templates.

Abstract classes impact performance, sometimes significantly, and it doesn't solve all problems templates solve. If you don't care, then you would probably be better off doing Java (or languages in the same family) than C++.

If you are not using genericity at all, it may actually be a good thing! Too much abstraction is a common problem. But sometimes you need it. Refusing to use generics will limit what you can do. And if it is your job, it will probably limit your pay too.
Many years ago, I created a 'gold hack' for fun for a popular game when I was in highschool. I reverse-engineered the 'encrypted' (which was basic letter shifting) password stored for the account and my hack basically just decrypted the password and emailed me the username/password.

As many are fond of saying these days, everything is political, whether it tries to or not. But what makes me say this is a political project more than a technical one is that consistently, as in TFA, the thing people say draws them to Gleam is this statement on the home page.

And again: lpil has explicitly said that they're not stopping with intolerance, they enforce "good vibes". That's what I'm worried about on a practical level: I don't believe you can build a healthy technical community that solves real problems on that foundation.

I very well might be wrong, and I believe that that's the point of this political experiment. But I also think it's important to emphasize that that's what this is: a political experiment, not just a programming language.
Hi. Seemed promising and I like the visuals but seems to not have todo lists which I thought bullet journals .. have?

Cool! Though the data must be a bit noisy as you get some oddities. For instance, if you select Astoria/Ditmars (last top, NW Queens) the Flushing/Main Street stop (last stop of purple -- go directly west on map from Astoria) is out of range. Click Flushing/Mains Street, though, and Astoria/Ditmars is in the 40 minute range.
This might interest you: Writing a C Compiler by Nora Sandler (No Starch Press). You create a working C compiler that outputs x64 assembly language in the first chapter (as long as the program only returns an integer from main) and then you keep adding features one by one for the rest of the book. You can write the compiler in any language you like (I’m using Python) and you only write the compiler while using your system’s precompiler (the step that handles #include and #define etc and removes comments), linker, and assembler. You just read preprocessed C as text and output assembly as text.

The thing that makes it relevant for learning assembly is that’s what you’re outputting so you’ll be learning that as well as what’s going on with the stack when calling and returning from functions and using local variables and basically everything that corresponds to C. (I’m only on chapter 2.)

Some other reasons it might work out for you is that you are getting into C as well already, and you have a familiar language you could use for the compiler if you wanted: java (assuming it doesn’t take too long to compile and run a java program repeatedly)

The Trouble with Aggregates
Am I the only one that thinks TypeScript types are a terrible choice?

His solution is clever, but if that's indicative of how he's going to do engineering work at my company, I guess that means I can expect clever solutions for everything, which usually leads to esoteric, architect astronaut code bases that will be difficult for his non-clever colleagues to grok/maintain.

"Now the easy part! I just have to encode the numbers in base 15 and I could apply the 2 and 5 rule to 3 and 5!" Encoding things in base 15 is too clever for me.

Back to the original statement I made: TS types are a terrible choice because TS types are not debuggable. If you get too fancy with them, you need a god in TypeScript to debug because you cannot set breakpoints inside of types and step through to see how generics and constraints propagate (as would be required by a mere mortal in order to debug).

"Hey, there's a bug in Joe's fizzbuzz function, but he's out on PTO, can you fix?"

"Sure, I'll step through with a debugger real quick... Oh wait, it's 100% typescript types, I can't step through with a debugger. I took a look but it looks like it's encoding numbers into base 15 for some reason... I don't want to break anything further, let's just wait for Joe to get back"

"Actually, can you just re-write it using normal conditional flow logic? We want more than just Joe to be able to touch the code."

This is just like "Cloud-native" isn't it. Well, at least we are close to the peak.
The level of redundancy in the NYC subway is marvelous. In most of the densest areas, you have 4-track lines and often other lines within a mile. It makes it possible to do maintenance while still offering 24/7 service.
This not a necessary outcome of connected grids though. Technology has advanced a lot in the past two decades.
“Connect” doesn’t have to mean “operate as a closely coupled synchronized grid”.

Using HVDC (which is more efficient over long distances anyway), adjacent grids basically appear as just another power plant to yours (and some early HVDC connections literally consisted of a motor coupled to a generator!), and grids ought to be able to stomach the sudden outage of one.
I agree with the parent about conciseness being a welcome feature in the character limit. However, I recognize many people don't like it and have observed people cheating it with chain replies. Making everyone sum up all of their thoughts up into a few sentences however fun for some (me) can be overly restrictive or impossible for others.

Probably also depends how comfortable you are sharing deep or personal thoughts with others. Also how much you are interested in reading about a particular person's thoughts. In my case I don't know enough people that care about the things I'm enthusiastic about so I've built up a habit of being direct and to the point.

It depends on your world view. There was also harm prevented, so that might cancel it out. You could also see it as a punishment, though not delivered by the judicial system. Your solution seems to be to do nothing. That can be construed as silent approval. So it really depends on your world view.
Yeah, I'm pretty sure the typescript solution was way beyond the skill level of the interviewer.

Which is fine.

But what's unacceptable is that a lot of people in our industry are not mature enough to admit when they don't know something, and instead just chalk it off as "unreadable" or some other adjective.
They care a lot more about robustness, maintenance, max continuous power, than cost, volume, or short duration ratings. Commuter trains are used for a decade and half, then sold to developing nation to be used couple more. No surprise that they're choose rack batteries with thick cables to bus bars over plastic packs in trays, if they even consider using degradable batteries at all.

Let’s talk about the raises I have gotten from job hopping since 2014. I have been working a lot longer.

But if the company could pay me more and thought I was worth more, then why didn’t they offer me that in the first place?

2012 I was working for a then F10 company (GE) after two years of across the board 3% raises, I left for a 25% raise in 2014. The manager couldn’t push for larger raises at GE. The entire team of 15 left within 6 months.

Stayed at the next medium size company for 2 years and no raises. Left for another medium sized company for a 20% raise.

Stayed there for two years and did a vertical move to get the chance to be on the ground floor when a startup hired a new CTO who wanted to bring all of the development in house and wanted to be “cloud native”.

Two and half years later a job at BigTech fell into my lap - a 40% increase in comp.

I was at BigTech for 3 years and took a pay cut when I left. But by then, I valued piece of mind and work life balance over money. Within a year of me working at the company, my current employer reached out to me. Pay was the same. But it was more aligned to what I wanted to do, better benefits and most importantly, unlimited PTO and I fully expect to take 30 days off this year.

None of the HR departments at any of the companies were going to be willing to go from 4% raises to 20-40% raises.
