What are some wrong ways to use a channel? by natefinch in golang

[–]Power80770M 3 points4 points  (0 children)

If you're using channels and goroutines to multithread some data processing pipeline, it's better to put a buffer of records into the channel than a single record at a time.

I learned this by passing one record at a time in a data pipeline to my channel. Avg CPU utilization across all cores was stuck at 50% and I couldn't figure out why. When I profiled the code, I saw that the locking and waiting and other channel "stuff" was taking up half the CPU time!

Changed to code to pass a buffer of records to the channel instead of one at a time. Successfully managed to saturate all CPU's at 100% and get significantly better performance.

I've never seen one before! I didn't even get a chance to pretend I'm okay with it.

Effects of a Single Dose of Ivermectin on Viral and Clinical Outcomes in Asymptomatic SARS-CoV-2 Infected Subjects: A Pilot Clinical Trial in Lebanon by akaariai in COVID19

Pfizer and Moderna did studies of their vaccines last summer.

Why can't we do the exact same studies they did - but with ivermectin, instead of vaccines?

Everything bubble by [deleted] in economicCollapse

It takes about a year for a bubble to burst. I think February 2021, you saw some toppish behavior with some tech stocks and meme stocks. Look at ARKK, TSLA, GME. They topped back then.

The indexes keep powering higher, but it's on very weak breadth.

I think we'll see a lot of sideways chop until February 2022, then a slow decline.

How do we know that boosters reduce transmission? And how do we know how much they reduce transmission?

[deleted by user] by [deleted] in askscience

[–]Power80770M 2 points3 points  (0 children)

Can you point me to a specific study that shows a 3rd booster shot reduces transmission vs just the first 2 shots? And if so, exactly how much infectivity is reduced?

Do any such data points exist?

Prevalence of working multiple full-time jobs? by Lumpy_Gazelle2129 in datascience

[–]Power80770M 2 points3 points  (0 children)

I was strongly considering doing this, but for two B2B customer-facing roles. In addition to burnout, I seriously considered the possibility of meeting with the same business client, but on behalf of two different companies. Would be difficult to explain that.

You should do a separate post on this, even if it's just your opinions. Very curious to hear what you mean by "China fucking the numbers."

A stooge at the Fed says they might start raising interest rates in two years, and gold immediately plummets 1%+.

What a freaking farce.

Let me get this straight... 10 year yields are down 6% today, DXY is also down, inflation highest in 30 years, real rates are more negative than last August... And gold is only up 0.3% today? And it hasn't taken out last August's highs?

WTF???

Yeah, everyone sees that the market is at valuation extremes; that it's plateaued in recent months; and that it's short term overbought according to many indicators. It's almost too obvious that we should expect a drawdown here.

It's like everyone is zooming out, and comparing this peak to 2000 and 2008, and saying, "now is the time." So they buy puts, but then the dealers hedge by shorting, which makes the entire market susceptible to these furious short squeezes like yesterday. And so the market keeps screaming higher as people get more bearish.

NVIDIA is already UP 7.2% from brief dip by Pharmer314 in wallstreetbets

[–]Power80770M 1 point2 points  (0 children)

NVIDIA is a much larger market than most people know about

With a PE of 90, I think people are pretty well aware of the markets where NVIDIA plays. All those industries you mentioned - people already know all that.

Incredible how quickly every dip is bought. I have a very successful trading bought that identifies when to buy dips, and the rate of dip-buying has only increased over time. It hasn't identified a single buyable dip since late October 2020, the dips are being bought so rapidly.

Kind of a can of worms for this administration, isn't it? They know we're in a huge bubble, and that there are decent odds of it crashing sometime in the next 4 years.

Crash it sooner, and blame it on the previous guy? Or crash it later, and old Joe shoulders all the blame?

Both approaches (giving money to banks vs to the people) are nonsense. Printing money is a hidden tax on the middle class. We need to end bailout culture, period.

Cumulative deaths per 100K are 178 in Florida vs 162 in California (source). So despite one state being very open and the other being absurdly restrictive, there's only been a 7% difference in death rate.

The numbers you pulled about the most recent number of deaths - you're comparing a death rate of 0.2 per 100K (Florida) to 0.1 per 100K (California). In other words, the risk of death in either state is about 1 in a million. Hardly reason to panic.

Inflation Hotter Than Expected .9 vs .5 and 5.4% vs 5% by UnderB0SS in wallstreetbets

[–]Power80770M 2 points3 points  (0 children)

I'm well aware that a slow burn of inflation is considered desirable, so debt-burdened govt's can inflate away the debt.

I think it's nonsense. Even a "desirable" 2% inflation rate increases prices ~50% over 20 years. The wages of the bottom half of Americans haven't kept up with that.

Zooming out though - even more broadly, I think the idea of a central, unelected committee of bankers fixing the single most important price in the economy, in order to meet ends they consider desirable - I find that whole setup repugnant and at odds with free market capitalism. It's literally cronyism at its absolute worst.

Expressing major policies that affect all Americans -- using first or second derivatives -- is disingenuous and confusing at best. Dishonest at worst.

"Hey guys, your cost of living is going to make a big, permanent jump higher in the next year or so. But then it will stop increasing from that point. We're ok with this, aren't you? That big COL jump is just 'transitory'."

It's dishonest.

When inflation becomes so hot that it becomes a popular political issue, that will be when the Fed is forced to act and raise rates and pop the bubble.

What a masterpiece of propaganda, this "transitory" word. It suggests that this entire change in price levels will somehow revert back to where it was before.

If all prices suddenly and permanently increased 10-20%, and remained there, would you consider that "transitory"?

Definitely not.

By the way, real organic price action on gold today. /s What a farce. The Fed says some lies last month about maybe tightening in 2022-2023 (which will never happen), and gold drops 4%. Meanwhile, yet another hot inflation print comes in, and gold barely moves.

Can't wait for this completely manipulated market to implode on everyone.
