a-wu··on Show HN: Dashboard for tracking insider trading at S&P 500 companies
Appears to be hugged to death.
a-wu··on Play social games with friends over Zoom
Seems like on desktop the links on the homepage are broken but they work from the hamburger menu. Interestingly, the homepage links work on mobile.
a-wu··on Performance, Protection, and Sterilization of Face Mask Materials
Right. I should've phrased the question as: is the copper content sufficiently high enough to make a significant impact on the disinfection rate compared to just say, cotton? Obviously it won't make a difference (I think?) during wear, but if it the virus dies quicker than on cotton then one could potentially disinfect the mask less frequently.
a-wu··on Performance, Protection, and Sterilization of Face Mask Materials
There's been a lot of press about people making their own face masks out of fabric and it got me thinking about copper-impregnated fabric (if you watch enough late-night TV you'll have seen those CopperFit infomercials). Copper itself has antimicrobial properties (studies say SARS-CoV-2 only lives 4 hours on copper), but does anyone know if there is enough copper content in those fabrics to make them a better fabric for face masks than cotton?
a-wu··on How the Zoom macOS installer does its job without you clicking ‘install’
Does this also work for non-brew installs?
a-wu··on Ask HN: How would you improve this bash oneliner for deleting tweets?
I've tried this before in a Python script but quickly got rate limited by the 300 tweet update limit [0]. Does this get around that?

a-wu··on Don't Touch Ya Face
Even better: get a copper spoon as copper is naturally antimicrobial

a-wu··on Robinhood maxed out credit line last month amid market tumult
Fidelity offers fractional shares now: https://www.fidelity.com/trading/fractional-shares
a-wu··on The Warby Parker clones are imploding
Warby will reimburse $50 to go to an eye doctor for fitting. See "Fit" here: https://www.warbyparker.com/help. I admittedly haven't needed to do this so I'm not sure what the experience is like.
a-wu··on Mastercard investing in technology to identify commuters by gait, heartbeat
I use an electric wheelchair. I'd like to see them try to identify me by gait. (yes, I'm likely more identifiable by other means)
a-wu··on The Aloha point-of-sale system
I agree. I thought the article was interesting but it felt unfinished.
a-wu··on MOV is Turing-complete (2013) [pdf]

a-wu··on I had to get a background check for my job; the report is a 300 page pdf
Oooooooh I’ve been meaning to write a similar tool but you already did it so that’s perfect! Quick question: is it possible to specify a date to delete tweets before or do I need to calculate the number of days? Also what happens if the number of tweets is greater than 3200?
a-wu··on IntelliJ IDEA 2020.1 EAP is open
> With v2020.1 EAP we are fully moving to JetBrains Runtime 11 (JBR11), and will no longer distribute builds with JetBrains Runtime 8 (JBR8). Please note that all the IntelliJ IDEA 2020.1 updates both in the IDE and the Toolbox App are coming with JBR11.

Does this mean I need to have JDK 11 installed too? We're still using JDK 8 because Spark 2.x doesn't support JDK 11, and having multiple JDKs sounds like a pain.

edit: nvm. Looks like JBR doesn't have a JDK dependency.

a-wu··on SpaceX tests black satellite to reduce ‘megaconstellation’ threat to astronomy
This is really cool
a-wu··on SpaceX tests black satellite to reduce ‘megaconstellation’ threat to astronomy
I have no experience in astronomy or satellites, but here's my naive idea. The article suggested erasing trails from the images using software. If SpaceX made an open API that detailed the precise location of every satellite at every point in time, could the imaging software use this to know that at this location in the image there is definitively a satellite that can be erased? I'm not sure what kind of sensors these telescopes use, and it probably wouldn't solve the issue of the bright spot messing up the exposure, but at least you could get rid of the trails?
a-wu··on Disney+ hit by technical glitches on launch day
I actually used to have better service when WatchESPN was standalone. When they started integrating into the main ESPN site (and new player) it started declining for me.
a-wu··on Disney+ hit by technical glitches on launch day
ESPN's streaming is one of the worst ones I've ever used. It is constantly buffering on my 275 Mbps downlink and every other time it has issues with authenticating to my provider.
a-wu··on AirPods Pro
Says $249 here too

a-wu··on Some tea bags may shed billions of microplastics per cup
At the higher-end grocery stores near me (Whole Foods, Nugget, etc), you can bring your own container and tare it before filling. Maybe you can see if your local grocery store can do this at the deli/olive bar?
a-wu··on Reddit was down for over two hours
Marked as resolved now, mods should probably update the title.
a-wu··on Tilde.club is giving accounts to waitlist
Is this similar to sdf.org?
a-wu··on Squirrels listen in to birds' conversations as signal of safety
Reminds me of this: https://www.youtube.com/watch?v=ouwtdH2zt9s
a-wu··on Software made me loathe my car
In iOS 13, manufacturers will be able to integrate the second screen with CarPlay. Whether or not they will is too be seen.
a-wu··on America has no use for hides, so leather prices plunge
I would recommend r/goodyearwelt for recommendations on boots. Really knowledgeable community without being too snobbish (imo).

I’ve found some pretty good leather jacket threads on Styleforum. There’s another forum whose name is escaping my mind, but they are dedicated to classic reproduction leather jackets.

a-wu··on US Rules Airlines Must Allow Miniature Horses to Fly as Service Animals
I have no problems with this as a physically disabled person in the process of getting a service dog. Miniature horses are recognized service animals by the ADA as long as they are house broken, can be controlled by the owner, and the facility can accommodate the animal’s size without compromising safety. My only concern would be that last point, if the animal’s size puts people at risk of not accessing the emergency exits then I think airlines are well within their right to remove the animal.

I do have problems with the people who get fake certifications for their “service” animals to bring them on board. Service animals are highly trained and these fake service animals really give true service animals a bad look.

a-wu··on You’re Paying into a Broken System Whenever You Buy Something on iOS
There is a refund process[0]. I generally don’t play games on my phone or use non-essential apps so I haven’t used it often but it has always worked for me.

a-wu··on Developer Tropes: “Google Does It”
That reminds me of the time that the free bagels weren’t delivered to a few floors of my office once on accident. It was an absolute riot on Slack (ok I’m exaggerating but I’m serious when the complaints had >100 reactions). God forbid the people walk to another floor.
a-wu··on Apollo 11 Had a Hidden Hero: Software
That’s funny because I actually love the Hans Zimmer theme.
a-wu··on Apollo 11 Had a Hidden Hero: Software
I recently started listening to a fantastic podcast called 13 Minutes To The Moon[0] produced by the BBC. It’s a retelling of the last 13 minutes until the Apollo 11 lander touched down. Episode 2 talked about the software and the 1202 program code. They interviewed the Guidance controller who was only 26 at the time and talked about how the average age of the flight controllers was 27. I thought that was incredible, you don’t see that much responsibility placed in such junior people anymore.
