we find that fixing fossil ages to the midpoint or a random point drawn from within the stratigraphic age range leads to biases in divergence time estimates, while sampling fossil ages leads to estimates that are similar to inferences that employ the correct ages of fossils. Second, we show a comparison using an empirical dataset of extant and fossil cetaceans, which confirms that different methods of handling fossil age uncertainty lead to large differences in estimated node ages

Because the influence of early diagenetic cements on the bulk δ13Ccarb signal can, but need not be synchronized, chemostratigraphy should not be used as a stand-alone method for trans-continental correlation, and especially minor isotopic shifts have to be interpreted with utmost care

Chemostratigraphic correlation based on bulk sediment carbon isotopes is increasingly used to facilitate high-resolution correlation over large distances, but complications arise from a multitude of possible influences from local differences in biological, diagenetic and physico-chemical factors on individual δ13C records that can mask the global signal

Their arguments also don't make sense: they encrypt messages on Android, even though it has disk encryption as standard, but they won't encrypt messages on desktop which doesn't have disk encryption as standard!

Encryption is present on Signal-android because android's FDE is not usable enough, in Moxie's opinion (you can't set separate unlock and FDE pins, so people set really insecure ones). If/when android fixes this, signal-android will stop encrypting its database, too. Just like signal-desktop and signal-iOS.

I'm locking this conversation because the conversation has clearly run its course. Any continued discussion can happen on the forums.

The database key was never intended to be a secret. At-rest encryption is not something that Signal Desktop is currently trying to provide or has ever claimed to provide. Full-disk encryption can be enabled at the OS level on most desktop platforms.

I think the difficult thing for everybody to understand is why the database is encrypted in the first place? Are you saying that SQLCipher just offered better features and performance than using SQLite? Can you point to any discussion or documentation of that decision-making process?

However, because so many shells follow that convention of having 128 + signal_number, programs know to avoid using those values above 128 for their exit code (or when they do exit(130), it's to report the death of a child that dies of a signal 2 like some shells do under some circumstances).

Both kill with a job specifier and terminal signals send to the entire process group, so both the shell and sleep.

I am trying to understand how CTRL+C terminates a child but not a parent process. I see this behavior in some script shells like bash where you can start some long-running process and then terminate it by entering CTRL-C and the control returns to the shell. Could you explain how does it work and in particular why isn't the parent (shell) process terminated? Does the shell have to do some special handling of CTRL+C event and if yes what exactly does it do?

Remove your last "just in case" trap, and the script should work fine also with the EXIT traps. INT in the trap calling the cleanup should be the correct way to deal with the interrupts, however

In a way, the notification center on a mobile device has become the federation point for all communication apps, similar to how older desktop IM clients unified communication across multiple IM networks.

Experimental schemes like caching pre-generated temporary keys from the clients on the servers increase the server and protocol complexity, leading to lower reliability and more potential for mistakes that impact security.

In 2013, the Signal Protocol was introduced, which is based on OTR Messaging and the Silent Circle Instant Messaging Protocol (SCIMP). It brought about support for asynchronous communication ("offline messages") as its major new feature, as well as better resilience with distorted order of messages and simpler support for conversations with multiple participants.[11] OMEMO, introduced in an Android XMPP client called Conversations in 2015, integrates the Double Ratchet Algorithm used in Signal into the instant messaging protocol XMPP ("Jabber") and also enables encryption of file transfers. In the autumn of 2015 it was submitted to the XMPP Standards Foundation for standardisation.

The biggest advantage of matrix/megolm is that you can always add new client logins, that aren't tied to your mobile phone login (as opposed to whatsapp/signal).

As uber-secure messaging platform Signal has warned, “Signal is recommended by the United States military. It is routinely used by senators and their staff. American allies in the EU Commission are Signal users too. End-to-end encryption is fundamental to the safety, security, and privacy of conversations worldwide.”

When you make a call using Signal, it will generate a two-word secret code on both the profiles. You will speak the first word and the recipient will check it. Then he will speak the second word and you can check it on your end. If both the words match, the call has not been intercepted and connected to the correct profile

First, the recognition that sensitive information needs to be transmitted securely over instant messaging platforms plays into the hands of the privacy advocates who are against backdoors in the end-to-end encryption used on WhatsApp, Signal, Wickr, iMessage and others. The core argument from the privacy lobby is that a backdoor will almost certainly be exploited by bad actors. Clearly, the EU (and others) would not risk their own comms with such a vulnerability.

The most popular modern secure messaging tool is Signal, which won the Levchin Prize at Real World Cryptography for its cryptographic privacy design. Signal currently requires phone numbers for all its users. It does this not because Signal wants to collect contact information for its users, but rather because Signal is allergic to it: using phone numbers means Signal can piggyback on the contact lists users already have, rather than storing those lists on its servers. A core design goal of the most important secure messenger is to avoid keeping a record of who’s talking to whom. Not every modern secure messenger is as conscientious as Signal. But they’re all better than Internet email, which doesn’t just collect metadata, but actively broadcasts it. Email on the Internet is a collaboration between many different providers; and each hop on its store-and-forward is another point at which metadata is logged. .
