That's true if the project manager's personal and organizational incentives are to make estimates that are as accurate as possible.

For some people and organizations, the purpose of estimates is not primarily informational.

This is not "statistics" it is simple facts. Japan is highly populated.
Something to keep in mind: several sources of actual topics have contradicted Donut Media views on certain things and DM has been known to steal video clips without crediting where they got them or use Wikipedia articles as established sources.

> The GitHub estimate is only using known resources and reserves, a number which goes up every year as we discover more. It is not an estimate of total accessible lithium.

Yes, it is. 5 minutes is the amount provided by known reserves. 19 minutes is what can be provided with all accessible lithium. This is known reserves, plus the amount we expect to find later.

> I don't know where that number comes from on that page, but it's wrong. More than 2GWh were connected to the US grid in Q4 2020 alone:

Which amounts to a whopping... 14 seconds worth of energy storage.

> And even if your number were right, it doesn't address the core point that battery storage deployment is growing at an absolutely incredible pace. In cost-competitive grids, it's replacing natural gas:

17 GW of natural gas was constructed in Texas alone. In fact, not even all of Texas, just the part serviced by ERCOT. Your claim "storage is being deployed in GW comparable to new natural gas GW" is not even remotely true, and your own sources prove it.

> This is just bad economics. These all affect each other. As production costs fall for lithium ion batteries, demand is growing, as shown by that RMI document. The cost of batteries is not falling because the demand is falling, the cost of lithium ion battery is primarily determined by manufacturing costs at the moment. The input costs of lithium is not going up because there's not enough lithium. And if supply of lithium does get constrained in the future, then there are alternative chemistries that are not supply limited.

The assumption that the price of lithium won't go up if we try to use it for grid storage is bad economics. Let me put the staggering mismatch between battery supply and storage demand in perspective:

* The US alone uses 500 GWh of electricity each hour. The world uses 2.5 TWh of electricity every hour.
* The entire world produces ~300 GWh of lithium ion batteries annually [1].

If we actually tried to provision one hour's worth of electricity storage the price of batteries would skyrocket, because there isn't enough supply to meet demand. We could provision one hour's worth of storage even if we bought every single lithium ion battery produced anywhere in the world for a whole year.

And this issue is going to become even worse as we switch from fossil fuels to electricity for heating, transportation, industrial chemical production, and so forth.

Why Generalists Struggle to Get Job Offers
Is it just me or recently in last year or so I am noticing more and more of ... I don't know what to call these:

- Baseball/pokemon card auctions

- Bitcoin and crypto in general

- Meme stocks

- and now this NFT stuff

It is all exploding. Usually, this was limited to much smaller stage and scale, besides may be the art world. Ofcourse auctions are older than the dust, I am just noticing increasing pyramid-schemes/tokens/scarcity-driven-value-stores and personalities such as deepfuckingvalue/elon/chamath/etc.

Is there an underlying pattern here?
>Their primary incentive is to create grad students who cite their work.

That's not true, the primary incentive is to generate new articles, which allow you to get more grants, which allow you to hire more grad students who generate even more articles.

And the primary incentive of the grad student is to write as many articles as well, because good articles are what will allow them to advance in the academy. So really, motivations of supervisors and grad students generally align, and abusive PIs basically sabotage themselves.

I've written a cryptocurrency trading bot in clojure that uses this approach very heavily. I typically send around a context variable (containing the database connection, logger, correlation-id and other ancillary stuff) as well as maps specific to the task I'm performing (orders, market data, etc).

I heavily use destructuring so that functions access the bits they care about, threading macros like (-> stuff (assoc :foo x) ...) and spec to make sure the maps have the structure and keys I expect and rely on non-existent keys returning nil by default. I also use the sequence functions heavily. Mapping, filtering and reducing over vectors of maps, group-by if I need them grouped and so on.

I personally find it to be a very pleasant way to program.

Deepfakes are risky business, warns creator of viral Tom Cruise
There are a lot of differences that need to be taken into account before making a comparison.

1. TimescaleDB implements the compression on a hifher level, the underlying table storage/access method remains the same

2. TimescaleDB doesn't compress latest data, allowing you to keep fast writes and edits for recent data, but also allows you to benefit from compression on row based data

3. Although not currently available, it is possible to have a TimescaleDB hypertable with a column based access method

4. Comparing would have to take into account the data model, access methods (types of queries), ingestion vs query comparison (batch vs real time), backfilling and editing, etc

I agree that this (Columnar) would be closer to Parquet.

Hyperinflation has always been caused by a deficit of production. The 1rst cause of this is the reapeated lack of investment in productive industries.

Printing money while your production drop? Yeah, bad recipe.
The Kalman Filter has been one of the toughest concepts for me to grasp over the years. I have looked at many examples related to target tracking, which logically makes sense to me given physical behavior of flying targets.

@Alenia, keep forging forward, know that opinions are subjective, and focus on helping the customer stay the course when the markets are down so they don't panic, and sell low and buy high. Objectively, this behavior is the biggest cost to investors. If you can help them through this, they will see fruit in time. The markets will go up and the markets will go down - it's the nature of the beast. Good luck to Alenia! Soon, the customer will tell you if you are or are not giving them what they need.

As to the market, at the end of the day no matter how much research and due diligence are applied, no matter how much you take EBITDA into account, it's still a roll of the dice. No one controls what fully moves the markets. Natural disasters, company fraud, deception, a CEO who has an affair, lack of company innovation, consumer fads, and shifts, etc. You can do all the research in the world and follow the best discipline but that's no guarantee. The markets have been programmed to swing when they shouldn't and not when they should. No different than when a company beats expectation but doesn't meet the "subjective" opinion of a few analysts and the stock tanks when in reality it should have risen, or at a minimum stayed flat. The entire financial world is subjective. If a company like Alenia can get investors to put money in the market in a moderate play, then over time that investor will or should in theory/historic make money. They may not have unrealistic returns like a few lottery winners out there do, but over time they will produce fruit. You can't play the same guitar with stocks and mutual funds - they have different strings.

I first learned about the Delphi Method from
the book Software Estimation: Demystifying the Black Art.

Although I have not used it in practice yet, I like the concept, especially for some more difficult (bigger) estimation tasks, so I am mentioning it in my book besides other "group estimation techniques".

It is true that this is basically async "planning poker".
If you look up non-English corpus, you can see an effect. Here in Spanish, but also in French and Italian ones.

https://books.google.com/ngrams/graph?content=Dan+Simmons%2C...

The effect can obviously be very little in an English corpus. The effect of Dan Simmons' books is mostly to introduce John Keats to casual readers and is even pronounced that these readers have no reason to have been exposed to Keats at school. They (including me) are obviously a low quality public who will not be interested with Keats' work over a long period, just a mere curiosity. They won't write books and won't create a market of books about the poet so I expect ngrams to be a mediocre measurement for this effect. It would be more interesting to look at Keats book yearly sales.
Yeah by the time you need two IDEs you might as well just get the suite.

If the only alternate is status quo, then it's not working very well is it for:

Yeah, this. Chinese culture is much older and more widespread than the CCP. The Chinatown here in San Francisco is older than the state of California. We had our first Chinese New Year Parade in 1851.

The Communists are the problem, and even then not unqualified: the CCP has lifted hundreds of millions of people out of relative poverty to economic prosperity, even as they do terrible things to Tibetans, Uighurs, and Falun Gong, among others.

Since you have a throwaway account, why not name and shame? At worst, it would give some information any student who was thinking about applying to your department.

Lab sciences tend to have accepted "the way things" go: your advisors got through some abuse too, so they think it's natural. I think some additional fuel comes from that you have to have an advisor to get into grad school. I'm from a field where the order is reversed (we have two years before finalizing our advisor, and changing is less of an hassle) and such abuse is much rarer. It might also have to do with my field's obsession with freely flowing information: people can just avoid advisors who are documented to be problematic.

As some kind of glue to bind this together, I offer you the plight of HB1 workers. They are tied to their jobs similarly to the way PhD students are tied to their advisors. Yes they could change their jobs, but it's a big hassle and leaves you at the risk of having to leave the country/dropping out of the program. And we also see tons of abuse directed specifically toward these workers, even when others have it good.

So my point is as long as you haven't forcibly bound yourself to a job, you're less likely to receive that kind of abuse. And in the worst case (if you encounter one of many, many shitty bosses), you can just leave for greener pastures.
Yeah or Google. They stopped Google Code (or whatever it was) to move it all to GitHub; I just assumed they'd then buy GitHub. Felt like a much more natural home for it.

Maybe Gitlab?
