In some ways the simple chord structure acts as scaffolding for the rest of the musicians to fill in with their own flavor. I really like listening to Jerry Garcia, I think he is the best guitar player there ever was so far. In a solo its like he lands every note your brain expects to hear next and just floats up and down the neck fast and slow. He was trained as a banjo player so it shows in his fingerwork. In the song "Deal," (1) the chorus chords are very simple - A G D, but Jerry is able to use his knowledge of scales to riff on these notes multiple different ways, and its almost like his guitar is singing its own lyrics.

No, algorithmic trading is not about leeching from anyone in any intrinsic way. Like all trading there are good and bad actors, and bad actors get a lot of press.

The two biggest roles that “algorithmic” or “high-frequency” or “electronic” traders play are:

- market making: someone has to warehouse a bunch of thing A a and thing B so that buyers or sellers can find a counter party. this used to be an Italian guy from Jersey called a “specialist” and he quoted in eighths so that the minimum he could make per unit was $0.125. he was not giving you a better deal than optiver.

- arbitrage: thing X costs a lot in Chicago and is cheap in New York, or vice versa. buy in the cheap place, raising the price, sell in the expensive place, lowering the price. wash/rinse/repeat: shit costs the same in both places now. people have been doing this since before the wheel, on foot.
Because the Republicans were hypocrites on this issue. No more and no less. "But Twitter is a private platform" is entirely a way for Democrats to wave that in their face.

Trump called Net Neutrality "Obamacare for the Internet" and gave Ajit Pai the power at the FCC to kill it. The GOP was all for "ISPs are private platforms" and "regulating ISPs violates their free speech" back then, when they thought they were on "their side".

To their credit, they were, kind of. Twitter decided to give Trump special treatment under their World Leaders policy, allowing him to break rules[0] with minimal consequences. They did this because Trump[1] gave Twitter clout and relevance that they wanted. This all changed after Jan 6; when a mob of extreme-right Trump supporters stormed the Capitol. Suddenly, big tech flip-flopped on Trump and decided they weren't going to serve extreme right-wingers anymore.

Republicans had taken tech companies as public utility for granted, while at the same time they were hard at work ensuring there would be no legal basis for actually regulating tech companies as public utilities. Yes, there's a few right-libertarian arguments[2] against this kind of regulation, but that entire wing of the GOP has been a lame duck for half a decade by now[3]. As far as I can tell, Republicans saw that liberals had been screaming their heads off about Comcast censoring the net, and that was apparently good enough justification to oppose Net Neutrality. The Stupid-Partisan wing of American politics wins again.

I'm not saying it's good that Twitter censors politicians that I don't like; of course. I'm saying that those politicians need to apologize and admit they were on the wrong side of the argument[4], because "censorship is OK when Comcast does it but not Twitter" is not a coherent argument. It's just self-dealing.

[0] Most egregiously: Donald Trump was exempted from DMCA 512 takedown notices, so if he used your song in a video and posted it on Twitter, you couldn't take down the tweet for stealing your song.

[1] More generally, any @POTUS account

[2] e.g. "How does Comcast pay for better routers if they can't double-bill Netflix"

[3] Source: I used to be deep into right-libertarianism back in college, during the "Ron Paul R[3vol]ution" days. As far as I can tell everyone involved either went alt-right, or left-libertarian. Or their name is Louis Rossman.

If you're wondering, I still support Net Neutrality and I think large social media platforms should also be regulated under common-carrier rules. However, I don't think even that should get Trump back on Twitter. The World Leaders policy was itself a common-carrier violation.

Could I ask what your process is for detecting whether a rewrite rule is still useful in subsequent versions of the DBMS? Do you read the release notes and test things out manually, or do you have an automated A/B test thing going on?

Additionally, have you ever had a rewrite rule change from being beneficial to being detrimental after upgrading versions? If so, how did you detect that?

Thanks!

Edit: Also, what considerations do you have for rewrite rule order? Do you find that it makes a significant difference in practice?
Nobody in any kind of profession are immune to scamming. People have bad days, you could be hit by a novel scam, or your accounts/systems could already be partially compromised—allowing an attacker more intel than you would expect them to have.

I’d caution any security professional or engineer to think they’re too smart or savvy to avoid this stuff. Assume you will be compromised at some point and make damn sure you can recover accounts or assets that are important to you. Failing that, get insured or figure out ways to mitigate the worst of your liabilities.
Almost all high powered people give some amount of shit jobs to their EAs and chief of staffs, it is par of the course in such jobs.

Haha indeed! Plenty of racist immigrants, more so among 2nd/3rd generation (then it all becomes a bit of a blur). It still churns my stomach to hear adult children of migrants - some of my peers, who themselves have done quite well - making disparaging comments about newcomers e.g. "they live on top of each other!", "they don't make an effort to assimilate!" etc - forgetting that they are describing the stories of our parents and grandparents (many of whom can still barely speak English). People have short memories and little empathy for "others"/"strangers" I guess.

I think the frustration of "competitive social pressures" combined with a desire for "simple solutions" is an achilles heel that gets ruthlessly exploited by fear mongers and outrage merchants, who use racist dog whistles to translate the resulting fear/anger into political capital. It appeals to the reptilian/emotive parts of our brain, and is very, very hard to shift via appeals to reason.(Don't know about you, but I can't wait for this election to be over just so I don't have to see another UAP billboard or cop another UAP robocall).
Ah, so Tcl's rules are dynamic scoping with extra steps. No wonder they're so mind-boggling.

Lexical scoping is the most straightforward, least surprising scoping strategy I've seen. With lexical closures it allows for some tremendously powerful constructs.

I guarantee you I pay my ISP every month primarily for downloading bandwidth, but for both ends at the end of the day. Netflix in turn pays their ISP. Those ISPs then have (potentially indirect) peering arrangements.

On top of this, Netflix offers to install CDN nodes within other ISP's networks to reduce that ISP's traffic across exchanges (connections between ISPs). If an ISP doesn't see the value in those and wants to treat Netflix like any other traffic that makes it's way to AWS, they're welcome to do so; it's just very not in their favor. Them using that as a cudgel to try and extort money out of Netflix is absurd.

> Reliable. For people that rely on their tools to be creative or appreciate design. You are paying a premium. See Apple for lots of examples.

Apple is basically the opposite of what you are saying. Apple products have moderate design in them that’s useful and they are also quite unreliable, but they still come with the premium. That premium funds their marketing and silicon development.
Beatles songs are great for this. If you play something like across the universe or dig a pony, these are simple enough chords. But you can actually very easily add all the little filler notes they do on the albums just from a few little riffs within those chords. You can even add your own and after a while you can start realizing you can do these little rips in all sorts of songs, touching pieces of the scale you are forming a chord on.
We are going to go back in circles, but as I said in the very first comment: mypy is the tool you want [0]. It won't do everything, but progress has been steady and more and more projects are providing type libraries for it.

But given that your response to the mypy recommendation was to complain (it's slow, it doesn't catch everything) then it makes it difficult to acknowledge the "valid criticism"... as in: people are working on it, what else do you want?

Even if you don’t there’s potential to develop comfort with it. I grew up with extremely itchy military surplus wool blankets. I thought I’d resent that my whole life… now having gone through a variety of other fabrics and fibers, I’d certainly prefer a nicer wool but I wouldn’t complain about those blankets anymore. I adjusted and came to appreciate them, and even learned to care for them so they’d be more comfortable.

On the other hand, you're probably writing your SQL parser to parse SQL queries that are being fed into some DBMS.

Unless you have the higher end H710 raid controller or whatever else, Red Hat rendered this chassis controller inoperable with their custom in-house kernel patching process.
There may be short term benefits to a keto diet, but longer term is not so clear. And health is only one element. Red meat is absolutely devastating to the environment and water supply, with immense greenhouse gas emissions, deforestation, and polluted water tables, on top of the incredible cruelty of factory farming and slaughter.

The carnivore diet is a thing, it’s probably closer to historical diets of Hunter gatherers.

Having done a couple of stints of meat + veggies only for 8-12 months I can definitely say you feel wired. I highly recommend, though it takes a couple weeks to break any carbs. I prefer it personally, but alas with multiple children and constant gatherings it’s hard to keep it up perfectly.

Real trick is snacks. I would make burgers and / or bacon and store it for a week or eat jerky. Worked well enough if I got hungry. After the first week or two your body adjusts to the protein & fat based meals and you no longer snack as much. At least not for me.

This one was quite a prime specimen, however.
I wonder why despite their ubiquity, there's almost no public awareness of polymers and their properties (outside of 3D printing enthusiasts), especially when compared to woods or metals. [a] I'm reminded of this by the slight misnomer of polyester fabric, which is actually polyethylene terephthalate (PET); the name polyester is more suited for polyurethane ester, and pairs with polyether (polyurethane ether). There's something similar with Styrofoam. [b]

At some point I decided to learn how to distinguish plastics (beyond relying on resin codes [1]), and found this excellent online tool [2] intended for museums to identify what plastic artefacts are made of based on easily observed properties. It also has general info for each type of polymer, including typical modes of degradation. I find great irony in how most common plastics nearly unpreventably degrade to unusable condition over the scale of decades (think, brittle old rubber bands or cracked and yellowed vintage computer cases), considering how the microplastics they degrade into are notorious for sticking around for millenia.

Learning about plastics has explained some phenomena I'd noticed before but had no idea behind the causes of:

- Why CD and cassette cases, both made of brittle clear PS (polystyrene), make a distinct sound when tapped and are so often cracked.

- Why some small plastic bags are milky clear, waxy, and not crinkly like most plastic bags: those are qualities typical of transparent PP (polypropylene); most bags are made of LDPE (low-density polyethylene).

- Why the black plastic of some food trays (e.g., those of microwave dinners) has a telltale wood-grain-like surface finish--this seems to be an unintentional trait of injection-moulded temperature-resistant food-safe PP.

[a] A decent fraction of people could say that steel is an alloy of iron with higher strength, that copper is commonly used in electrical wires, that pine is relatively soft and light, or what plywoods and fibreboards are made of.

[b] Styrofoam is a brand of extruded polystyrene foam (EPS) board used as insulation, but the genericized use refers to expanded polystyrene foam (XPS) instead. More trivia: Plastic bags and foam are just as recyclable as rigid plastics (not counting the economic reasons behind most plastics recycling going to landfill anyway)--most municipal recycling plants reject them simply because they're difficult for machines to handle.

The Current Estimates
Your Playdate Is In: Group #2
Group #1 ~1 to 10,000
Late 2021 → Now Early 2022

Group #2 ~10,000 to 20,000
Late 2021 → Now Early 2022

Group #3 ~20,000 to 30,000
Still 2022 (Second Half)

Group #4 ~30,000 to 40,000
Still 2022 (Second Half)

Group #5 ~40,000 to 50,000
Still 2022 (Late Second Half)

Kind of process of elimination if you make a distinction between early 2022 and second half, at this point early 2022 means by end of Q2.

Perhaps it is true that the federal government has no standards for brownfield cleanup, but that does not mean no standards exist. The California Water Quality Control Board and the Department of Toxic Substances Control are responsible for coordinating cleanups of these sites to objective standards required for habitation, commercial development, schools, parks, or whatever. You can see the DTSC activities for the Sherwin-Williams site at https://www.envirostor.dtsc.ca.gov/public/profile_report?glo...
This is exactly my conclusion, and it seems obvious... just look at the self assessment line - pretty much everyone thinks they are slightly above average. Once you know that everyone thinks they are above average, you already know how it will play out... the bottom quartile will have the biggest gap between actual skill and estimated skill.

I do the same, but with a lot of protein shakes (keto chow) as well. It works really really well for me.

I'll still eat low/no carb vegetables like cucumbers, pickles, broccoli, etc, however. A diet of no soluble fiber isn't workable for me.

IMO states' rights is a pretty nerdy issue if you take a step back and think about it. Very few people are such nerds.

you can, however, orbit 2 or 3 molynia orbit satellites that accomplish effectively the same concept of persistent coverage over a certain geographic area. The orbit would be calculated to put the long dwell time of the apogee of the molynia orbit of each satellite over the target area.

this is far more useful for anything that is sigint/communications based, or space based radar, than anything as a weapon.

Although not to the same level of accuracy as "hovering" over a specific longitude along the equator as in geostationary.
Yes, it has no direct connection. I think it was a chance to throw shade at Peterson, which is understandable.

Edit: I understand Peterson's appeal but I am not a fan because I think he's full of bs and himself. In the case of the drug addiction issue he blamed everybody but himself.

The credit score system is really about incentivizing you to get, use, and keep credit cards, including retail credit cards, and loans, i.e. take on debt.

The fact that so many things require a high credit score is a forcing function for you to take on these debt instruments, and the credit score is a way for the system to optimize that it get its money.

The entire system is gamed against the consumers unwittingly or unwillingly forced to participate.
