> Do you buy on Tuesday to exploit the pattern?

Well you would typically do both, as 2 separate signals, or even more as time horizons widen.

This modelling is part of the "physics" side of quantitative finance, and often revolves around the use of oscillators and other dynamic systems.

Try to picture the pattern of voltage oscillations when you suddenly release a switch. Price often converge in exactly the same fashion. You can create a whole convincing analogy between voltage oscillations, capacitors, resistors, and actors of the stock market.

The way to see it is that the price will most likely oscillate around the consensus price, until it more or less settles. The first part of the oscillation, right at the point of publication, will create a momentum from the current price, which will then overshoot to create a reversal, which will then overshoot to create an other momentum, etc. Each time a cycle of momentum / reversal switches, the amount of overshoot diminishes and the time horizon of correction increases.

To illustrate, let's imagine a news on ACME Corp, currently trading at $10, just got released saying that their earnings will be above expectations.

- In the first 30 seconds a strong momentum will drive the stock price from $10 to say $15.

- After the initial 30 seconds of momentum, the price will have most likely overshoot. Many factors will lead to this overshoot: abuse of market orders on news to get executed faster, imperfect execution of limit orders, genuine over-excitement from participants, delayed basket comparison computations, etc.

- From the 30th second to say the 15th minute, the overshoot will revert from $15 to say $13. People will compare ACME Corp to its sector, country and beta, they will realize it's overvalued and short it.

- After 15m the reversal will have overshoot to $13 and a new momentum will arrive until the end of the day, settling in on close at $14.

- After a week the original daily momentum will revert to $13.5 as slower mid-freqs catchup and agree on a more precise consensus price.

Etc

Overall the cycle of momentum / reversal did:

- 0m -> 30s : + $5

- 30s -> 15m : - $2

- 15m -> 1d : +$1

- 1d -> 1w : - $0.5
When people apply labels like these in this way, it always strikes me as thoroughly naive. Clicking through and seeing Poland get hit with the "developing" label basically confirms my suspicions that the author doesn't really know what they're talking about. This is the problem with focusing on single-dimensional abstract numbers which do a poor job of encapsulating complex ecosystems like an entire country. What's the water mark for a developed country? Iceland?

Much of world is currently in an economic contraction. Britain has its fair share of issues that need to be addressed. Pretending like it's anywhere close to places like Bangladesh or Cambodia is actually insane. That's not to say it can't fall to that level of destitution, or that it won't if action isn't taken. Brexit was always going to be a great economic shakeup, and it had the disastrous misfortune of occurring right before COVID drove a bulldozer through everybody's economy. I'm just certain that hyperbole like this ends up being harmful in the long-run, because people begin to associate the extant problems with overblown panic and then minimize and underestimate them.
There is certainly some meat to the argument, Britain is much poorer than it could be, but I think the GDP/salary comparisons and so on are completely tainted by financial speculation and manipulation, a decade of asset price inflation etc, and do not reflect fundamentals.

TL;DR: Firefox usually uses AV1. Hardware prior to intel 11th gen tiger lake, amd rdna2 (pre rtx 6000 series) and nvidia 3000 series has no hardware AV1 decoding support (and neither does Apple Silicon). This results in higher CPU usage on Firefox, whereas Safari and Chrome usually resort to codecs that have hardware decode support on the machine.

This can easily be fixed by going to `about:config` and setting `media.av1.enabled` to false.

I've been addressing my glucose intolerance issues through an ultra-low carb diet for over a decade, and while I've cut out almost all products with natural or artificial sweeteners, my two remaining sweeteners of choice are stevia and aspartame. I use a combination of those for the occasional baked good, such as almond cookies or pudding as per diabetic recipes from the 1800s [0]. The recipe calls for saccharin tablets, which were used as a sweetener for almost 100 years; the question I always ask is, "Did bladder cancer rates increase in diabetics using saccharin over almost 100 years?" If the answer is no, then why replace an inexpensive sweetener with Aspartame? If Aspartame has not created a wave of new cancers in its user base, then I ask myself, "Why replace another inexpensive sweetener with sucralose?"
When I started my new way of eating, I ordered sucralose drops (because at the time, I wanted to "test" all sweeteners), and while the drops themselves did not increase my blood glucose, to me, sucralose left a very sickly-sweet, unpleasant feeling at the back of my tongue. My pedestrian understanding of the process used to make sucralose is that it takes tons of sugar to create pounds of sucralose – not sure if that contributes to it being sickly-sweet.
The WHO is right in cautioning the use of any sweetener (natural or artificial), but it seems silly to single one out at this time. I'm confident that in 40 years, sucralose will be explicitly added to the list (and industry will switch yet again to the latest artificial sweetener).

Yes, there's a reason why, excuse the expression, capeshit movies have dominated the cinemas for the past 10-12 years. MCU movies probably pay for a lot of other high-quality movies - but they rely on those franchise movies to bring in the bucks.

The good thing is that most serious movie goes can easily ignore these movies, if they want to. The negative thing is that, well, those movies really do dominate they cinemas, and will get first priority on pretty much everything.

I'm from a small rural place, and back home they would screen nothing but the latest superhero movies for 3-4 weeks straight, when they got released. Other movies would either get passed on, or get screening time much later in the season. More often than not it was the former.

Do you really not understand? Have you never enjoyed something and wanted to share it with other people? "You have to watch this show!" or "You have to try this new restaurant!".

Are you saying those are statements that you can't understand why someone might make?

Think if it wasn't just something great, but one of the greatest things ever. An actual cornerstone of human existence and the experience responsible for civilization. One of the few things that clearly separates us from animals.

Imagine someone starving themself. Would you encourage, maybe even pressure them to eat more? Perhaps they are eating just enough calories to get by, not starving to death but not doing more than existing, not enjoying the abundance of earth and the fruits of that millions of years of human development have brought us.

How comfortable would you feel sitting at the table with them, while you sample a buffet of intricately prepared delicacies from around the world? How much credence would you give to their position that eating more than 1200 calories of rice a day is just their personal choice.

It's not the alcohol is the absolute greatest thing ever, but it's close. I can't think of much else that would provoke the backlash that banning alcohol would. There's not much else than you could ban that would create the depleted society we see in areas where alcohol is prohibited (for the peasantry at least).

Apple Maps cycling directions take me to the nearest intersection of a destination and instruct me to dismount if the remaining leg would require wrong-way cycling.

Hmmm a fellow lover of CPU performance counter :).

Couple of points :

> although its sampling: only every 1/1000th instruction or so gets profiled when these profilers get turned on

Not always, modern CPU ( intel's at least, not sure about arm and AMD), you can control the recorded event and the sampling event (and sampling rate) seperatly. So you can actually both record load/store misses and sample on cache misses to avoid loosing any events.

You still get some sampling artifacts like the fact that the triggering of event is biais in favor or start of Basic block or that some events can be shadowed by others ...

> if your instructions are (on average), waiting 10ns per load/store, you know that you're operating at the L2 cache level or so.

Not always, sometime if you have a chain of depends loads the resolution time of the load has more to do with data dependencies.
Intel's CPU has a collection of "precise" events, around caches events, so it's easy to just deduce precisely where a given loads resolves most of the time by doing the ration of L-cache misses/L cache hit dirrectly)

> When you see that some branch is mostly unpredicted, you know to focus on that branch/if statement to figure out how to get the branch predictor to work.

The hardest part here is to understand if the branch is unpredicted because it's unpredictable or because the branch predictor is not performing as expected : Branch predictors are limited resources, they can't predict all branch all the time.
Retail investors more or less know they're gambling. Employees are just expecting an honest wage for an honest day's work.
> but a small fare can add money in the system

That's the above poster's point; A small fare can easily cost more for infrastructure and enforcement than it brings into the system.

To the extreme, consider fare/ turnstile jumping. Requires

1. Ticket Sales (requires cash management, or credit card fees; $0.25 is a significant amount of $2.50)

2. Video or Person watching from turnstyle booth

3. Turnstile (that must be ADA, emergency, traveling with
a roller bag, traveling with children compatible)

4. An officer to identify and ticket the offender.

5. A District Attorney to pursue charges

6. A judge to hear a defense

7. a courthouse bursar

8. a warrant officer to arrest someone charged with a $2.50 fare jump

9. a jail cell.

The real cost though, is criminalization of the poor, in a high income inequality country.

I rarely took non-express busses when I lived in Seattle, but once took the bus into the international district for work and then had to get to 23rd & Jackson (about 20 blocks, straight shot). First I had to wait for a route that went straight down Jackson - 10-15 minutes. Then the bus ride - 30 minutes. Then the same thing on the way back. Nearly an hour and a half, not including having to walk a few blocks to get to my destination. In retrospect, walking would have been faster, and had I driven that day, round trip would have been around 20 minutes, with traffic including the pickup I needed to make.
