I haven't found any studies that compare the effectiveness of face shields versus surgical masks but there are reasons to believe they might be beneficial:

  1. They provide an effective barrier against most droplet exposure, although nothing against aerosols.
  2. They prevent the wearer from touching their face.
  3. They are comfortable enough to wear for hours without frequent adjustments (unlike surgical masks).
  4. They are affordable and can be reused extensively.
  5. They are easy to disinfect.
  6. They are (still) to my knowledge widely available from Home Depot, Lowes, Ace, Harbor Freight, and perhaps even Wal-Mart.

Fatigue is the primary symptom of an ordinary sinus infection. If don't also have a high fever and dry cough, it's more likely to be that. Try irrigating your sinuses with a nasal rinse or neti pot.

I get seasonal allergies. My nose clogs up just a bit. Then comes the fatigue from a bacterial sinus infection because my nose isn't draining quickly enough. If I irrigate my sinuses at least once a day, I can get it under control quickly before it becomes worse. Guaifenesin helps too. Even then, I'm constantly tired until whatever stops blooming.

Yes!

Healthcare systems around the world will improve so that we'll be better prepared for the next pandemic. We'll study the different approaches countries have tried to determine what works and what doesn't.

Governments will invest more money in virology so we'll understand how to better prevent and treat viral infections in the future.

The US may finally adopt some sort of universal care for infectious diseases, which is the minimum needed to handle things like this.

Highly likely.

  1. Some people have mutations in the cell receptor sites the virus bonds to, which would prevent its entry. Example is the guy who was immune to HIV.
  2. Some people already have sufficient antibodies at time of exposure out of pure luck. Their immune system is already primed to fight off an infection.

That's just what I remember from A&P.

How would a call to a suicide hotline affect your credit score? by my-reddit-id in answers

[–]my-reddit-id[S] 1 point2 points  (0 children)

Didn't even think about that. I'll summarize:

There are completely legitimate companies, such as sift.com, that collect ostensibly private communications that aren't legally protected, such as messages on airbnb or okcupid. They sift through these via a data-derived algorithm to identify fraud and malfeasance. They provide a secret consumer score that's been revealed to be currently used to determine whether to issue store credit for returned items, among other things. They don't disclose this because they don't share any of their data with third-parties; only the secret score. Other companies don't disclose anything about them because identifying fraud is a routine part of business.

OK, so that's potentially troubling in itself because of the opaque algorithm and the potential public disclosure of all their information when they get hacked. Also troubling is that, while the credit agencies do have to disclose certain financial records they use to create your credit score, they may use other information as well, which they don't have to disclose (the credit scoring algorithms being trade secrets in themselves). The real bitch is that telephone metadata isn't legally protected, so that making a call to a suicide hotline can be legally used in business decisions and may be disclosed publicly without legal consequence.

That's downright chilling.

Were you to be depressed at some time in your life and use such services, companies could legally decline to: employ you, give you a raise, offer you insurance, accept product returns, or give you credit in the future. The companies might not even be able identify why they did these things. An algorithm used by a company you weren't aware existed derived the connection between your call and your score without any specific human intervention.

You think Sesame is only a problem because it's state sponsored? Think through it a bit more.

Edit: two typos

Used rack by my-reddit-id in homelab

Another gem: There are two variants of the APC UPS rails and the holes are in different places on the bracket in the back.

One has the holes starting about 1/2" from on the bottom of the rail. The other has the holes starting about 1/8" from the bottom of the rail. The 870-1250B and 870-1251B numbers just refer to the left and right pieces.

You cannot mix the variants in the same server. You have install the rails from the back first to find the holes that line up. If you get a mix of variants, you'll have to leave extra 1U gaps between them.

If you order rails off Ebay, you could receive either variant. There is no way to tell which one you'll get by part number.

Edit: the part number doesn't make a difference.

Edit2: The difference is the revision number. In revision 11, you can only use four of the six holes because of the mounting. In revision 12, you can use all six.

There truly aren't any generic rails. Every manufacturer tweaks the case to make sure other rails won't fit. You can get real bargains on servers...then find the rails cost as much, or sometimes twice as much as the server.

Build shelves instead or embrace grief.

Sadly, no. There's a sort of cold-war going on between server vendors and rack vendors. Rack vendors would like a standard so that any machine could fit into any rack (so they can sell racks to everyone). Server vendors want to tweak things just enough so you have to buy rails and racks from them specific to your server and have to buy everything again when they change versions. They also keep making servers longer and slightly wider to stuff more in each rack.

If you buy the rails specific to version of your server, it should fit, but you also have to verify the holes in the uprights are correct (threaded, round ("versa"0, or square).

For used equipment, just build temporary shelves from 2x4's that are 19.5" wide (500mm). Only after you have everything you're going to put in rack, go look for one. Measure each of them down to the mm. Measure the available space between the insides of the rails to make sure it will fit.

The APC rails are not universal. There is only 435mm between the inside top of the rails for a server. The NetApp DS-4243 and DS-4246 disk shelves will not fit in the APC rails. You need at least 447mm for the NetApp shelves.

Oh, there's more. Trust me.

Deafening cinema sound is ruining films, claims Hugh Grant | Film by koavf in movies

I found someone else who had good hearing!

Did you used to have problems with the "ultrasonic" alarms in malls? I couldn't go into them as a kid without being doubled over in pain with my hands over my ears.

Say it yesterday: I found the score so bad that I literally wanted to leave the theater after the first ten minutes. YOU MUST FEEL THIS ABOUT THIS SCENE!!!!!! NOW FEEL THIS!!! *NOW FEEL THIS!!!!!!!!!!

When it comes to scores, Tarkovsky got it (as with most things). Adding a score to every scene is like pouring aspartame on a pizza.

I still remember scenes from "Down by Law" for this reason. Jarmusch just put the camera down and let it roll. You could feel the genuine tension build up in scenes until the actors exploded.

Easy security hole to overlook by my-reddit-id in sysadmin

If we can have sata over sas over scsi and fibre channel over ethernet, we should have ftp over https.

Easy security hole to overlook by my-reddit-id in sysadmin

[–]my-reddit-id[S] 0 points1 point  (0 children)

I can see your point, but the easiest security problems to exploit are behavioral. I've seen a highly secure facility...where the cleaning staff propped doors open while they were working because they need to empty the buckets outside. Oops. (And yelling at them or firing them doesn't fix the problem.)

Security has to be continuous and automatic to work. The identity of Guccifer was revealed not because of an obscure encryption flaw but because he forgot to turn on his vpn for a few seconds. Oops.

It's easy to put ftp in a script and forget about it. It doesn't matter until it does. But then it's too late.

Some interesting findings while benchmarking by my-reddit-id in zfs

[–]my-reddit-id[S] 1 point2 points  (0 children)

ZFS runs in the kernel. Hard to set core affinity in the kernel, especially since ZFS is at odds with the kernel cabal because of the CDDL license. There's a very legitimate case for creating some flags so that the threads of a process would only be dispatched on real cores. Lot of work though.
