Yes, electrostatic speakers are a good example. Also a lot of PC motherboards I've had over the years have had the little piezoelectric speaker. And while still magnetic, there are planar magnetic speakers which are much more like electrostatic speakers (just using a magnetic field instead of electric field) than the typical moving coil / dynamic speaker drivers that you think of.
> The practical benefit of FIPS 140 is less that your crypto is better and more that your systems will fail to establish connections with anything not using FIPS mode, thus reducing your threat exposure.
No, I don't think so.
If I'm running, say, a TLS listener (an HTTPS web server), there is no way for you to tell if I'm using a FIPS-validated implementation of the algorithms or not. I can be using a cipher suite that is allowed by FIPS, but that doesn't mean my implementation is FIPS-validated. It's not like there's a "FIPS validated and FIPS mode enabled" flag added to the TLS spec, and even if there was, there'd be nothing stopping me from setting it to true even when using a non-validated implementation.
But MEPs can't even introduce legislation, they have to get all of Parliament to ask the European Commission to initiate legislation, and the Commissioners are pretty far removed from direct election. Nobody elected by the citizens can initiate legislation.
From the news release "What does this mean?" section: "This update to the Covered List does not prohibit the import, sale, or use of any existing device models the FCC previously authorized."
So no, this does not pull all existing routers off the market. Anything that already got FCC approval remains approved and new stock may be imported and sold.
Is there really any correlation between tax revenue and spending at the federal level anymore? It seems the U.S. government is willing to spend at huge deficit levels. If everyone stopped paying federal taxes I suspect nothing would change.
What would change is the government would need to greatly increase their debt. In 2025 the government got about $5.23 trillion in tax revenue and spent about $7 trillion. So most of the government spending is financed by taxes. Remove that and the rate of debt quadruples (and by extension inflation).
Fact is US is able to run up 39 trillion and counting in debt because it prints the god damn monopoly money. No one would offer a loan to someone with that financial history. Shit really went off the rails after Bretton-Woods, huh?
Ha,you beat me to it! That book was my first thought when I saw this post. I have a copy sitting here on my bookshelf.
Just to expand on how bonkers this book is... they assume that everyone has easy access to a Forth implementation. So they teach you how to build a Lisp on top of it. Then they use the Lisp you just built to build a Prolog. Then, finally, they do what the topic of the book actually is: build a simple expert system on top of that Prolog.
To be fair, in the 1980s thanks to the Forth Interest Group (FIG), free implementations of Forth existed for most platforms at a time when most programming languages were commercial products selling for $100 or more (in 1980s dollars). It's still pretty weird, but more understandable with that in mind.
And if you want to go farther back, even if it wasn't called "mmap" or a specific function you had to invoke -- there were operating systems that used a "single-level store" (notably MULTICS and IBM's AS/400..err OS/400... err i5 OS... err today IBM i [seriously, IBM, pick a name and stick with it]) where the interface to disk storage on the platform is that the entire disk storage/filesystem is always mapped into the same address space as the rest of your process's memory. Memory-mapped files were basically the only interface there was, and the operating system "magically" persisted certain areas of your memory to permanent storage.
From everything I've read about aphantasia, I'm certain it described me -- I have absolutely no ability to consciously "visualize" things in my head (I was also surprised to learn that some/most people sometimes experience a smell sensation if they recall smells, or "hear" music when they think about music or have a song stuck in their head, etc.)
Really the only thing in my head is my internal monologue. If I'm thinking about something I've seen, it's my internal monologue "saying," with words, physical attributes I remember about it. If a song is stuck in my head, it's my internal monologue (in my own voice) signing the lyrics or my own voice humming the tune in my head. No sensation of it being the original artist or the actual instruments, it's 100% my own voice in my own head.
I have a friend who says she does not have any inner monologue at all, and thinks entirely visually. I can't imagine! We're on the pretty extreme opposite ends of the spectrum of how we think, apparently.
I still remember (semantically) that my parents laughed at me, when they told me to count sheep to fall asleep and I told them all I can see is darkness and white dots when I close my eyes. They probably thought I was joking.
> What is the point of setting up your own email server if all of your sent messages go to spam for the majority of gmail/o365 users?
I set up a new mailserver a few years ago and have had no delivery problems whatsoever. All messages get through to gmail and outlook/o365 inboxes I've sent to. Didn't even have to register the IP with O365, it's just worked flawlessly from day one. That was from an IP address/netblock not associated with cloud or VPS providers, so initial reputation may have been higher.
A few months ago I set up a mail server on a VM in Digital Ocean, and have had no delivery problems to gmail/Google Apps recipients.
More recently, for new IPs sending mail into O365, they appear to be blocked by default but the rejection message gives you a URL to go to where you can register your IP(s). After doing that, we haven't seen any problems.
If you end up getting an IP that has been associated with previous spam or abuse, I assume your experience will be different. But in my experience, my handful of servers have not had delivery problems. This is all, of course, with proper reverse DNS records that match what the server advertises in its HELO/EHLO, SPF and DKIM all set up, etc.
Yeah there are shadow blocks on all these major email services. I have just slowly asking my circles to stop using them.
And I'm NOT just talking about gmail, Rackspace and ATT as well. (Proton and Tuta are good default for non tech ppl ATM.)
For more regular email user, it is better that one host or find some reliable person or entity that can host your email under domain that your own.
