Hi Peter, at what age does it start to become more difficult to get a work visa, and does it depend on the type of visa it is?


I don't think old age is a factor; the issue is more when someone very young applies for a work visa, such as a prodigy applying for an O-1, because there is general skepticism about the applicant's qualifications/achievements.


This is why I always use an encrypted file system, where the encryption keys are only known to the client (and not the NAS or other storage provider).


I just use an old computer full of drives on which I ssh mount. I don't even care setting up samba these days.

Even NAS distros/OSes are usually overkill for home and less than 5 different users. In a typical family context you usually only need one filesystem for each user + 1 shared fs with same RW for everyone.


Exactly - just a Linux box, mounted with SSHFS. To be fair, I have spent some time over the years writing my own scripts for SMART alerts, but the end result is better monitoring and alerting than a NAS would provide.


Euros exist in physical form (notes and coins). There is a digital form of Euros already, called "reserves". However, only banks and other financial institutions are able to hold these reserves (they are allowed to have reserve accounts at the ECB).

What you have in your bank account is "credit" from the bank to you. You can currently ask to withdraw this credit in the form of physical Euros.

A "Digital Euro" would mean that regular people could hold digital Euros at an account they hold with the ECB, just like the large financial institutions do.

This could be useful to allow the ECB to fight price deflation, because:

1. The ECB can directly credit the accounts of hundreds of millions of Europeans (without having to go via banks). This would mean they could fine-tune policy by depositing small amounts every single day in every single account. This solves the "pushing-on-a-string" problem of the ECB making it cheap for banks to lend, but finding that the banks are still unwilling to lend or that people are unwilling to borrow. The ECB could also decide to only top-up the accounts of people with low balances, so that aid is targeted.

2. The ECB can more effectively increase money velocity by enforcing negative interest rates. You can currently avoid negative interest rates by simply withdrawing physical Euros from your bank. But if the ECB discontinues or restricts the availability of physical Euros, you will only be able to withdraw Digital Euros from your bank. If your Euros are digital, you cannot avoid a negative interest rate.

Although price deflation is great if you have money or are owed money, price deflation makes it difficult for people who owe money to repay their loans. This is because their labor is earning them less money each year compared to the debt they owe. This is why the ECB and other central banks are very concerned about price deflation.


Price deflation is only of concern to debtors with fixed rate loans. For those with variable rate loans the rate will tend to drop during deflationary periods.


I agree, if the lender makes cheaper credit available, and if borrowers are automatically provided with drops in their loan rates. If borrowers have to shop around for a better deal and pay fees in the process, this would dull the effect of a lower base rate.

Some other reasons that the ECB wishes to fight deflation are described here:

It's important for the US dollar to maintain reasonably constant and predictable purchasing power from year to year. This is part of their dual mandate. Their target is just under 2% inflation per year, as measured by the Core-PCE index. If the dollar didn't have reasonably constant and predictable purchasing power, people would be afraid either to issue or to take out loans denominated in USD.

Manipulating the supply of the dollar via interest rate adjustments, along with open market operations, is how the Fed attempts to control inflation.


I notice that the OpenJDK build is only available as a .tar.gz and not as .rpm

This means that to upgrade from Oracle JDK10 -> Open JDK11, you'll have to write a script yourself to modify the symlinks e.g. to redirect the existing "/etc/alternatives/java -> /usr/java/jdk-10.0.x/bin/java" to the new installation. There are 46 of these symlinks that need changing (for javac, jstack, etc etc).

I hope that's the only change that is required and that I'm not missing something. Anyone know if there is anything else necessary?

Edit: here is the script I just wrote to print out the commands required to change the symlinks:

  #!/bin/bash

  existingJdkBinPath=$(dirname `readlink /etc/alternatives/java`)
  newJdkPath="/opt/jdk-11"

  find /etc/alternatives -type l | while read link; do
    target=$(readlink "$link")
    targetPath=$(dirname $target)
    targetFile=$(basename $target)

    if [[ $targetPath = $existingJdkBinPath ]]; then
      newTarget="$newJdkPath/bin/$targetFile"
      echo ln -snf "$newTarget" "$link"
    fi
  done


The OpenJDK build is GPL and should find its way into official package repositories. Oracle may have stopped creating the rpms for that reason.

Most distros use the IceTea builds for OpenJDK. Hmm . IceTea3 is Java8. There's no Java9 IceTea4 build yet. I can't find any roadmap info on their site ...


Do you happen to know how much Cloudflare charges for this?


Because then you have counterparty risk, which means you then have greater regulatory/compliance costs and have to pay up to 0.4% on assets for FDIC insurance.


Counterparty risk on Fed Funds loans, which are for one day only and to solid, highly regulated financial institutions, is negligible - that's why it's treated as the risk-free rate.

Would you need FDIC insurance if you only took deposits from financial institutions?


> Why is it so crucial to their business model that the customers' deposits are deposited directly with the Fed

Note that whether interest was earned via IOER or via the Fed Funds market, the funds would be deposited with the Fed either way (whether in the bank's own Fed account or overnight in the Fed account of the counterparty of a Fed funds loan).

It wouldn't be possible to accept transfers from other banks, to send funds to other banks or to participate in the Fed Funds market unless the bank had an account with the Fed.

On the point of "risk-free", the TED spread was north of 1% for much of the 20 months between August 2007 and April 2009, and peaked at over 4%. So it's not always what I'd call negligible risk. https://fred.stlouisfed.org/series/TEDRATE


The "Confidential Transactions" scheme for cryptocurrencies uses homomorphic encryption.

The idea is that you can prove that the encrypted input and output amounts in a transaction balance to zero, without having to actually reveal what any of those amounts are.

See https://people.xiph.org/~greg/confidential_values.txt


CTs don't use homomorphic encryption. They use "additively homomorphic commitments" which are, essentially, cryptographic proofs.
