siberianbear··on Ethereum Is a Dark Forest
I travel a lot, and sometimes often to "emerging economies". Cash is always king, especially when your American bank puts yet another suspected fraud alert on your card...
siberianbear··on Ethereum Is a Dark Forest
Fidelity Investments brokerage and cash management accounts have a limit of $1000 a day, and I have four of them, so I can get $4000.

I recently learned that some Chase Bank ATMs inside branches used with Chase ATM cards can get $3000 in one transaction. I did it the first time a few days ago.

siberianbear··on The wildest insurance fraud scheme in Texas
What is an airplane game scheme?
siberianbear··on Partying like it’s 1999 – Initial public offerings are back in Silicon Valley
Is this true in general?

The Silicon Valley company I worked at for a long time started out with ISOs, then as the company grew scrapped ISOs in favor of NSQ (nonqualifed options) and then later scrapped those and just gave RSUs.

The move from ISO->NSQ had some tax advantage to the company even though it is obviously worse for the employees.

siberianbear··on Connecting the Atari ST to the Internet with an ESP8266 (2017)
In Sacramento around 1990 there were monthly MIDI Maze meetups where we would all network our computers with MIDI and play. I was popular at these meetups because I had two Atari STs and would always bring them both.

We occasionally got up to the maximum of 16 players, but it got a little slow and unstable sometimes. We usually tried to form multiple rings of 6-10 computers.

siberianbear··on U.S. eyes building nuclear power plants on the moon, Mars
It makes sense. Voyager I was powered with nuclear energy.

siberianbear··on Nazis in our classes: 50-year-old lesson about fascism still terrifying us today
For me, your link gave an error: "Something went wrong. We're sorry. This page failed to Outline."
siberianbear··on Open IP over VHF/UHF
Is this a thought experiment, or does the FCC really do this?

It's hard for me to imagine that they have an army of radio engineers to go looking at all signals, figuring out which ones are "undecipherable", physically identifying the transmit locations and then determining who did it.

siberianbear··on Cleaning My MacBook After 16800 Hours of Use
Yes, it's true. You can see this for yourself if you turn the can upside down while you press down the button on the top. Then, it will spray liquid solvent out, which will immediately vaporize, and therefore rapidly chill anything it's on.

In my former life debugging signal timing issues on circuit boards I used to use this trick (using those "gas duster" cans upside down) to chill individual components to try to find out where the problem was.

siberianbear··on Weird Keyboards, Programmable Keyboards
The first keyboard he referred to was the original IBM "clicky" keyboard (aka Buckling Spring keyboard) which is still available new. The right to manufacture it has been sold to a company called Unicomp. [1] They've ditched the legacy connector and now it will work with USB.

I personally own one of these and I love it. It causes less carpel tunnel problems for me because the keys travel more and they don't bottom out quite abruptly.

The only downside is that it is very noisy. If you can type at 80 wpm like me and you work in an open cube environment, you'll make your cube neighbors crazy. I no longer work in a shared office so nobody cares and I enjoy the clicky sound.

siberianbear··on Last Airworthy MiG-17 Is Up for Sale
The question I really wanted answered was "how much is he asking for it?" I did a lot of searches on various search engines but couldn't find the answer. I guess it falls into that "if you have to ask, you can't afford it" category.

I did find a classified ad for the plane. The owner's phone number is there.

siberianbear··on Let Game Theory Tell You When It’s Time to Go Shopping
You would think there should be some sort of reward in the form of saved time from going to the supermarket at an unpopular time. But my closest supermarket changes the staffing levels at checkout to coincide with the level of shoppers. So, I spend the same amount of time in line no matter when I go.
siberianbear··on Container technologies at Coinbase: Why Kubernetes is not part of our stack
They've having some growing pain. It's normal in a company growing at Coinbase's pace.
siberianbear··on Protests about police brutality are met with wave of police brutality across US
If the police ignore hooliganism on the streets, it just invites more hooliganism.

If the police brutally put down hooliganism, it also invites more hooliganism.

Probably, the right solution involves better policing of police, and throwing out the bad apples. But police culture is very insular, and their labor unions have quite a bit of political power. They protect their own. So, that's easier said than done.

It's quite a catch-22 situation.

siberianbear··on There’s plenty of room at the Top: computer performance after Moore’s law
Google Docs isn't a great example. In WordPerfect's case, WordPerfect was the product and there was an incentive to make it great.

Google Docs isn't the product. It's free. You're the product. And it only needs to be good enough to keep competitors from creating something so great that it removes their first-mover advantage. It's clear that Google has given up developing new features for it.

siberianbear··on Signal app downloads spike as US protesters seek message encryption
I'm no expert on the subject, but probably the use of phone numbers (and confirmation by SMS) is helpful to limit the number of bots.
siberianbear··on Human Hibernation Is a Real Possibility
That can't be right, because salt water freezes at a point a few degrees below fresh water. Now, 0F is defined where fresh water freezes.
siberianbear··on Individual Investors Get Burned by Collapse of Complex Securities
If you do this yourself and feel comfortable, good for you.

But I wouldn't widely suggest people lever up 2x using margin. It's dangerous advice. In a severe down market you can be wiped out with a margin call and forced to sell at a low point in the market.

siberianbear··on Facebook Employees Begin to Revolt
One man's racism is another man's free speech.

Just like one man's terrorist is another man's freedom fighter.

Facebook and the other SV tech companies have a clear political bias that often seems like selective and directed censorship.

siberianbear··on Image Scrubber: tool for anonymizing photographs taken at protests
That wasn't really a "blur", though. A swirl like that is just moving pixels around. If know how the algorithm works, you can reverse it. Probably, it was done with a common program like Adobe Photoshop or Gimp or something. One could write a program that would just "unswirl" with various parameters and generate a bunch of images, and a human could pick out the one that looks like an unswirled image. If you can pick out the right paramaters to the unswirl, then no image information is lost.

That can't be done with a blur. In a blur, pixels are merged or averaged together and information is lost. In some cases you could sharpen it a little, but it's still not going to be as good as the original image. In a really good blur, even the best sharpen algorithm isn't going to give you something that looks like an identifiable face.

siberianbear··on Can 1/3 and 1/3 = 2/6? It seemed so
One of the things I've realized in life is the best teachers are people who were not very good at something and then became very good at it through sheer practice and grit.

People who are naturally gifted at something because they can't understand the reason for someone else's failure can't teach well.

I worked for a year of work study as a math tutor at a community college. "How to do integration by parts[1]?" one student asked? That's easy to explain. My hardest day was when I was trying to help this one woman understand that when you multiply two negative numbers you get a positive numbers. "Wouldn't that make it more negative?" she asked.

I decided I would have been a terrible math teacher even though I was very good at math. And reading this article was interesting to me because it explained to me why I would be a terrible math teacher.

siberianbear··on Shhh: The Undocumented DOS Commands (1999)
I remember learning about "FDISK /mbr" from a DEC support tech support line. I rescued several hard disks with that command that other people had deemed "broken".
siberianbear··on Coronavirus will end the golden age for college towns
I was very active in the university recruiting effort at large Silicon Valley for many years. I went to tons of university career fairs. This statement is wholly true. At the undergraduate, the majority of students were US citizens (but there were still a lot of foreigners). But at the master's and PhD levels, virtually everyone was a foreigner.
siberianbear··on Whale fall
Here's what a "Whale Fail" is [1]. In 1970, a whale died near Portland, Oregon and washed up on the beach. The local authorities decided to blow it up using explosives, with awful and unexpected results.

siberianbear··on The Lord of the Flies: when six boys were shipwrecked for 15 months
My interpretation of "The Lord of the Flies" didn't have anything to do with islands or shipwrecks. The purpose of the novel was to demonstrate the raw cruelty that teenagers in a group, such as the ones you or I went to high school with. The author was trying to show up what a stupid, cruel system we'd set up for ourselves and how senselessly mean we were to one another.
siberianbear··on Flying: It’s Worse Than You Think
There's something that I'm not getting in all this: given the R0 for this virus, the situation isn't going to disappear until about 70% of the population has developed immunity.

The purpose of all these isolation and social distancing measures is to slow down the process in order not to overwhelm hospitals. But the news reports I've been reading about hospitals is that in general, in developed countries, the hospitals aren't overwhelmed.

If 70% or so haven't developed immunity, then the pandemic will just re-emerge as soon as the restrictions are lifted. It seems to me that eventually 70% are going to get it. Shouldn't we just let it loose and go through our destined suffering faster?

So why are we making ourselves go through all this? ELI5?

siberianbear··on Ask HN: Who has been laid off?
That's an interesting response. It seems to me that the flame level on this site is quite low in response to somewhere like Reddit. People argue here, of course, but usually it's in an informational sort of way and rarely devolves into "yer momma is soooo fat...." kind of discourse.
siberianbear··on Hotels Hammered by Coronavirus Offer 14-Day Quarantine Packages
Thanks for the pointer to that tool, it worked for me and will probably help me get past a lot more paywalls.
siberianbear··on Understanding the bin, sbin, usr/bin, usr/sbin split (2010)
Don't feel too ashamed. I also learned a lot from this article and I've been using Linux/Unix boxes for even longer than you.
siberianbear··on Indonesian minister calls on rich to marry poor to cut country's poverty rate
The obvious problem is that there are a lot more poor people than there are rich people.
