Industrial control systems are experiencing the growing pains of letting go of older technology that was designed prior to security being much of a concern.

ICS networks are often designed to be 'air gapped'. All too often the air gap is broken via a vpn into the network so that someone can RDP to a windows scada machine (that doesn't receive updates because it can't reach the internet itself).

Confidential...as in only you, the recipients, Google, the NSA, and other intelligence agencies the NSA shares information with can read these emails.

I understand the sentiment. I certainly have my own bouts of intense paranoia related to security and the privacy of my personal stuff. It can become unhealthy. However, I think as long as the majority are complicit with email providers that don't offer end-to-end encryption, we may fall deeper into the clutches of government surveillance, targeted advertising, and other practices that IMO are an overall toxic influence on humanity. I don't practice what I preach at the moment but hopefully the loss of convenience is not too significant as I make the switch.

I have an XPS 15 9550 as well and primarily use ubuntu. I feel your pain on the failure to hibernate/heating up in a bag. Dell seems to have had plenty of issues with buggy BIOS and motherboards on this laptop. Last week mine became afflicted with the notorious XPS issue of powering itself on automatically immediately after shutdown (from windows or ubuntu) and will only respond to the power button being pushed if the charger is plugged in. I've replaced the battery and the CMOS battery in an unsuccessful attempt to solve the problem. Dell support said I could pay $70 to send in my laptop to get it diagnosed and then quote me an exorbitant price to replace the MOBO; all while being without a laptop for god knows how long... no thanks!

I resurrected a MacBook Air from 2013 and have been running Ubuntu for a week now. It's very refreshing to be on stable hardware even if it's not a powerhouse.

You're criticizing Tor for something that's impossible to solve. If you think that's possible then please open a ticket

Not criticizing tor. Just pointing out a couple of ways in which a tor user could give themselves up by doing stupid things while using tor.

Interesting stuff on timing based attacks. Thanks

If you access an http site, a government controlled exit node could inject js and eventually gather enough info through profiling mouse movements and browsing habits to ID you.

Even with https, if the feds are in cahoots with the certificate authorities, you would be just as vulnerable to this sort of injection right?

However, tor hidden services is another story. I think this is where a bad actor would hit a wall.

So we will inevitably end up with some variation of Proof of Stake protocol – where we will simply have to trust some users more than others

Doesn't this defeat the point? I can't imagine a scenario in which a proof of stake system does not become centralized. The average person will want to stake the extra money they have but won't want to maintain a dedicated machine with adequate storage and zero downtime. They will entrust a third party to earn money by staking on their behalf. Thus, you have created a centralized system with a whole bunch of extra complication.

I agree, VPS providers don't inherently provide any added security or privacy.There's not much that would stop these providers from jumping at an offer to hand over your data for a pile of cash. If you want privacy, use Tor. If you want to beef up security, check SSL and URL before entering creds. If you need to evade corporate firewall rules, a VPN can do the trick.

Regulation doesn't affect the ability of a currency to be influenced. It just puts that ability in the hands of a select few. The US govt prints money to pay off maturing debt. After some time, this scheme will come to a disastrous end. As long as there's trust in the central auth, both Tether and USD can survive.

Yes, since you can't trust the JS, doing this would be an attempt at security through obfuscation. I mostly just think it's strange that these keys aren't accessible. If there were ever a mismatch detected, the server could at least know with certainty that there's a bad actor on the connection.

Thanks for Zooko's Traingle wiki. Hadn't seen that one before.

Public key pinning helps but it operates on the assumption that the initial key is the correct one. I find it curious that these public keys are not readable by the client.

Yes, greater for security but still depends upon reliability of certificate authorities and ISPs. ISPs have the ability to issue the client a bogus certificate while they hold the real one in order to decrypt traffic. Why won't browsers allow the certificate's public key to be readable by javascript so that the remote server can verify the client has the correct certificate? This wouldn't be foolproof but it would significantly beef up security.

Similar to how tor hidden services get resolved, distributed hash tables seem like the way to go. Take the ISPs and Cert Authorities out of the equation.
