Atomic oxygen resistance is a consideration for any object in Earth orbit, and now it seems to be relevant for the moon as well. It would be interesting to know the oxygen flux and to study the Apollo hardware left on the moon for corrosion and erosion.

Interestingly enough, ozone (O3) is a concern for rubber objects on the earth's surface. Modern engineering rubbers are stabilized against ozone attack.

What horrible sulfur/oxygen species will we find around Venus?


An 18650 is 65mm long. I think "eighteen six fifty" is more euphonic than "eighteen sixty five". A 2170 is 70mm long


And what sort of health and financial information does Facebook have?


They are profiling like crazy. I'm pretty sure they have at least an estimated income attached to almost every single of us. Also, they do have credit card numbers for those who buy ads.

But it may have just been a generic statement.


Interesting, I looked at getting my own. It's free, but they will send it via snail mail.


US mail is more secure than emailing it to you.


Is it? I trust Google more than postal workers / people who live near me.


You can go after your neighbors. It's inadvisable, but it's much more tractable than taking on Google.


In my case they mailed me a piece of paper with an access code on it, which led to a site with an encrypted PDF containing my report. The password to the PDF was the same as the access code I got.


I'm curious what progress has been made on this. I didn't find across any recent sources when googling.


It's basically required in South Korea for online shopping. The link to the IE 0 day is written in Korean.

More on IE in South Korea: https://www.nationthailand.com/Startup_and_IT/30321025


No longer required by the government as of recently: https://www.theregister.com/2020/12/10/south_korea_activex_c...

Unsure on whether major sites have gotten around to removing it though, perhaps a Korean HN reader could comment.


I remember IE was required for the South Korean government issued digital certificate (required for all internet-based retail transactions and likely others).

I guess I had assumed that the standard was compatible with newer versions of Windows or MS browsers. Really sad if it isn’t.


For some things in SK you have to download a bunch of weird proprietary government .exe's that seem to only run in conjunction with specific combinations of windows and IE. I was pretty shocked when my wife and I went to get our marriage certificate from the government, and going to get our marriage certificate was finding an old windows NT system at her college library that everyone used to do their government related .exe stuff. We had to download 2 or 3 apps to do it, I'm not even sure what they all did, just a bunch of programs you had to run in a specific order, some of them provided iFrame type windows to logins, it was really strange.


I wonder why they needed an active x control for that. TLS/SSL client certificates have been supported by all browsers since basically forever, going back even further than active x.


If I had to guess, HTTPS / SSL was governed by US export restrictions above a certain strength so S Korea managed to use the existing extensibility built into the browser the government wanted to support.


It's ActiveX-based, which essentially runs nowhere but IE. Edge's support for ActiveX is running it in an IE tab.


Yes, I roughly understand the limitations of the existing implementation. but it is not the only browser or platform and it’s not like the S Korean government is not capable of noticing the market share / cybersecurity trends of the past decade+.


I was under the impression that SK was a technologically advanced country. I guess not the government then.


If Microsoft suddenly disabled all IE installations in South Korea, they'd have no choice but to change. Sometimes I wonder if the Apple-style "this just won't work at all anymore" attitude isn't that bad.


It has its places, given the correct trade-off, it works well. Not allowing flash was good because iOS was a growing market with no preexisting businesses relying on flash on iOS to work.


Sounds like a great way for Microsoft to lose a lot of market share fast.


There's no ActiveX on macOS or Linux either.


Not in SK, but in China Here basically all banks require ActiveX, and if you don't have an Windows computer(Mac), what you can do is to use their app, which of course is super sluggish.


This is probably it, thank you for clarifying - I've got a few friends in SK and they always complain about this, should have thought of that!


Do you know the latest on IE use? The article I posted is from 2017 and promises modernization.

I submitted the article here, hopefully we get an on-the-ground update. https://news.ycombinator.com/item?id=26656052



This will be awesome in countries where I can't read the signage.


The difficulty is linking two tweets to each other. You don't know the url of a tweet when posting, but there are patterns in how the ID is assigned and it's possible to tweet likely guesses until you have success.

Stack Overflow is much better than Quora. Quora has gone downhill over the last few years with paid contributions and modal nags. It sea they will also sign me in after I click a link in their email digests. I don't know how that can be secure
