Comment Dumb journalism (Score 2) 55

While one can reasonably argue if depreciation should be 3 or 6 years, the article is utterly dumb, quote:
> "However, some types of assets fall in value more sharply early on, then stabilize and decline more gradually on a predictable curve. A case in point: According to Silicon Data, which tracks pricing for Nvidia chips, the average resale value for an H100 system in its third year of use recently was around 45% of the price for a new H100."

1) Depreciation is unrelated to market value. Real estate is depreciated over 30 years, whether or not the value is increased or decreased.
Useful life is however long the item is actually used and contributes to company P&L -- unless otherwise declared so by accounting guidelines. There are no binding guidelines here.

2) Annual depreciation _could_ be taken (but usually isn't) as "book value - salvage value" / useful life. Using the numbers in article, if 2.5 years in, value of asset is 45% of purchase price, annual depreciation is ~55%/2.5 = 22% -- resulting in exactly the same depreciation as a 5 year accounting schedule.

"managed to transform what was once a labor cost (i.e., supervising work and asset protection) into a revenue stream through the sale of doorbell cameras and subscription services to residents who then perform the labor of securing their own doorstep."

Epi.org has no links to unions that I can find.

I don't think you have looked much.

directly from wikipedia: Eight labor unions made a five-year funding pledge to EPI at its inception: AFSCME, United Auto Workers, United Steelworkers, United Mine Workers, International Association of Machinists, Communications Workers of America, Service Employees International Union, and United Food and Commercial Workers Union.[15] According to EPI, about 29% of its funding between 2005 and 2009 was supplied by labor unions and about 53% came from foundation grants.[7]

Comment freedom of activism (Score 1) 43

Bethany is a anti-chinese-government activist using LinkedIn as a social media platform. I think it speaks a lot about freedom of speech in China, when an anti-china-government activist is concerned about the visibility of her profile _in_ China.

Whereas, if it was a sufficiently inappropriate person in the US, they would be banned from social media worldwide "due to community guidelines"

Comment Actual reduction (Score 5, Informative) 232

This is a pretty interesting study that isn't quite captured in press release. Pages 23,24,27 are good summaries

The important parts:
Wearing surgical mask has ~11% reduction on seroprevalence, with high degree of confidence.
Wearing cloth mask has ~5% reduction on seroprevalence, but p-factor is 0.5, meaning this result is meaningless.

Interestingly, the effect is much stronger regarding "symptoms" (which would generally include other diseases, such as cold)
Wearing surgical mask has ~14% reduction on symptoms, with high degree of confidence
Wearing cloth mask has ~9% reduction on symptoms, with high degree of confidence

Now, the interesting parts are when seroprevalence is broken down by age (a
For >60 year old, seroprevalence decrease is 34%, high confidence
For 50-60 year old, seroprevalence decrease is 23%, high confidence
For 40, and 40-50 year old, there is no meaningful change
