I remember using PHLAK (Professional Hackers Linux Assault Kit) that I'm pretty sure was based on Knoppix. I don't know if PHLAK actually had any pedigree heading into Kali, but Kali stepped up when PHLAK stopped.
Oh my. I had a GBA that me and my dad modded to be backlit. Boktai was so good on that system. I didn't think about how lucky I was that I could play the game pretty easily.
Microsoft to buy a communications platform? I guess today's Microsoft isn't the same one that bought Skype but this comedy video of the "Skype CEO" is terribly relevant.
It's funny, because as I remember it, locking down multiple-person video chats was about when they started to die. They even briefly touch on that in the video, too.
I remember that they did some other stupid things around the same time, but not what they were.
What's your preferred terminology? I like "Forward" and "Reverse" for positive and negative number and "Lateral" for the imaginary unit, since it is just perpendicular to the Forward and Reverse numbers.
That's pretty close to what Gauss said they should be called:
"If ... +1, -1, and √-1 had been called direct, inverse and lateral units, instead of positive, negative, and imaginary (or impossible) units, such an obscurity would have been out of the question"
I just think of them as different axes on a 2D Cartesian plane. That’s basically how they work.
EDIT: similarly, quaternions as a number in 4D, with that extra dimension being handy for avoiding the instability problems when you get near “gimbal lock” in 3D rotations.
That it more an effect of how we use them in computer geometry. Unit quaternions with ijk plus real map to an xyz tilt plus a rotor. But I believe you could pick any such mapping.
On the other hand, dual quaternions do care which is the dual component, since multiplying by complex numbers looks like true rotation, while multiplying by a dual looks like rotation around a point at infinity, aka translation.
So in that case maybe there is something special about the real component.

Close. Alabama Senator Shelby is the Chairman of the Committee on Appropriations and the Chairman of its Defense Subcommittee.
Edit: My apologies. Was the chairman. See nobody's comment below.
Interesting. Python is my go to teaching language. It beat the snot out of learning programming with Java. As a newbie, what does "public static void main" mean? So what's your choice for a teaching language? Maybe Lua or Scheme? They seem to have few surprises which is good for teaching.
BASIC, for explaining the fundamentals of imperative programming. Its weakness as a "real" language is its strength as a training language.
Then Scheme, once they feel straightjacketed with BASIC; it will teach them what abstraction is and how to break code into chunks. It should be a bit of a lightbulb moment. They also get a type system.
Finally, Julia, once they get sick of the parentheses and difficulty of building "real" programs (you'll do a lot of DIY FFI to use standard libraries in Scheme). From this they will also learn array programming and the idea of a type hierarchy.
The only trouble with this curriculum is the student will be completely ruined for ever programming in C or Java. They will not have learned to tolerate the requisite level of tedium, or even programming without a REPL.
This paper might be useful [0]. It measures the thickness of a tissue. If you do that over time you can detect the parts that aren't moving. I studied under Yezzi for a while. Cool dude.
Awesome, thank you for the reference. That's the essence of finding regional wall motion abornomalities. When looking at the ultrasound I look for parts of the myocardium that don't change in size relative to their neighbors during the cardiac cycle.
I find it fascinating that in that ad the schlubs that are sitting there watching the television are Fortnite default skins and not say, replicas of the characters that hold the same position in the original Apple ad. This really supports Dan Olson manufactured discontent assertion[0].
Even if you support them and play their game, if you don't spend money for skins, you're still in Big Brother's audience. The wildest thing is that the Jackboots behind the hammer thrower are approximate replicas of the Apple Ad.
I don't play games anymore and I'm not a big fan of the whole microtransactions/F2P model, but I found that video somewhat uncompelling.
Not that long ago, the MMO standard was $15 a month* (plus the initial $50+). Not to unlock the cool stuff, but simply to play at all. And nobody felt like there was anything sinister about it.
With Fortnite, you can play for free as much as you like, or (based on what I gathered from the video) pay <$10 every 2.5 months to be on the cool track. Seems like a pretty good deal in comparison, assuming that they're rolling out new (non-shop) content at a reasonable rate.
Even if you support them and play their game
How are you supporting them if you don't pay? Sure, they benefit from network effects, but ultimately they obviously need a lot of paying customers. Have we really gotten to the point where people expect to play AAA games for free and view it as audacious if the developers incentivize people to pay for things? As mentioned, I did much prefer the old model because it precluded this kind of stuff from seeping into the experience, but I don't think there's anything fundamentally sinister or wrong with trying to push people towards paying for your game (though I will say the "let me see your Marsh Walk emote" stuff was pretty cringey, but that's another story).
*I realize that Fortnite is not an MMO but it seems to fit the bill for something you would pay a subscription for these days. You could hold the Battle Pass for over a year for the classic $50-60 game price.
I have some friends in the employ of the federal government, who was raised Catholic. One time we were having a conversation that started about the Catholic church. He said is that some of the decisions of the Catholics are odd and slow because they are making decisions on the scale of a hundred years. They intend to be around by then.
The USA Feds seem to be on a similar plan, but it's more like a 10 year lag, and it finally seems to them like this HTTPS thing isn't just a fad.
Funnily enough the official website for the Holy See is also not HTTPS encrypted. (http://www.vatican.va)
This is a really good point. Organizations that play a stabilization role tend to benefit from this kind of dampened response to the various proddings of rapidly evolving tech.
