*rubber duck thread* Using the Sega CD subcpu in mode 1 is very doable but the larger problem is: what kind of tasks can we hand off to it, and are they asynchronous?

 We can't run code directly off the cart from the subcpu. We can't simply make the faster cpu run the game. So it makes more sense that we'd have subroutines running on the subcpu to accelerate common operations that can be called from the MD main cpu.
But we run into a problem here. First is defining what "common operations" would really be. Since the subcpu is another 68k with a roughly 50% higher clock, it wouldn't make much sense to run very small or atomic operations on it. There is overhead in passing arguments...
... because it has to be done in shared memory. Overhead could kill the gains. We'd get more benefit from a larger, more complex function to really take advantage of that higher clock speed. This adds another layer to the problem, synchronicity.
If the MD cpu has to block (stop and wait for a result from the subcpu) we're losing a lot of potential throughput. The effect is similar the other way around in that we also waste resources on the subcpu waiting for a command from the MD.
(BTW this is why using the dual SH2s on the Saturn wasn't super popular, as it requires a similar semaphore setup. The game would have to be carefully crafted to utilize it at the planning stages.)
If you can set up a task that runs asynchronously, that is, both CPUs working away, then that's ideal. It's just that for a lot of games, this isn't really feasible or useful. Most game loops on this old hardware are essentially single threaded and each step is done in order...
...every time, for every frame, and if there isn't time to do it all? Slowdowns. This isn't true of every game of the era, but it's true the vast majority of the time. So ultimately, this makes the entire approach not attractive for rom hacks. Much like a Saturn game...
...you'd have to arrange the game loop as such to not waste time and resources. To do certain things asynchronously. Nearly impossible for a rom hack. But what about homebrew and new games going forward? There is a bit of promise here but still some caveats.
The best reason to use the subcpu is to get access to the cd hardware features: the disc drive, the PCM, the additional RAM, the ASIC graphics scaling features. Using it to accelerate CPU bound operations is probably not worthwhile.
What if you designed a game to use resources carefully, though? You're still a bit hampered by the fact that the two CPUs can't run the same code out of the same memory, so no clever threading tricks. Also at this point you may as well be making a a Sega CD game!
To this end I'm experimenting with creating a small library, intended for homebrew, but similar to MSU-MD, that will allow the user to play PCM, CDDA, and (hopefully!) use the scaler. I don't know if this will mature and it depends on how useful it ultimately is.

THREAD ON IRONFLY

These days the most preferred strategy for option sellers due to improved margins is IRONFLY. It's essentially a short straddle with long strangle. Long strangle acting as 'WINGS', which help in capping the unlimited risk associated with a short straddle.(1/n)

You can also view the position as a combination of Cal & Put credit spreads, if that makes it more easy for you.

There are 3 important things to understand while trading this strategy:

1) Initial size of the Wings
2) Risk Management
3) Adjustments

(2/n)

Since we are selling an ATM straddle, the 1st question is how far our wings should be? Ideally i sell .50 delta straddle & buy .20 or .10 OTM strangle, depending on my view on volatility. So the distance of wings depends on the IV setup. Higher the IVs, greater the distance.(3/n)

If you don't understand greeks, then ideally with 30 days to expiry (dte), wings should be around 300pts either side. If your trading in weekly then it should be not more than 200pts. Higher the premiums, higher the distance as we have more cushion of theta. (4/n)

It is important to understand that we need to reduce the distance of wings with time so as to manage our RISK in gap openings or sudden volatile move. So for eg. if you started with 300pt wings with 30dte, the wings wouldn't give the same protection when there is 7dte. (5/n)

🧵 @DianeLangberg wrote about NDAs in Christian environments, noting “An NDA is an agreement to hide something. In the cases I have encountered it has always been an agreement to exercise power over and hide sin.... [it is] unlike our Lord.”
1/

NDAs are traditionally “non-disclosure” - don’t talk about specific X. Often in church/ministry cases - they’re overly broad - don’t talk abt *anything* re: your employment

but also may include

“non-disparagement” - don’t say anything negative about us EVEN IF IT IS TRUE
2/

Numerous articles have described the use of NDAs in Christian environments and the conflict with principles described in the very faith supposedly being promoted. I’m linking them here then I’ll offer my 20-year lawyer and victim of silencing (gag order) take on the practice.
3/

“Silence of the sheep” (2018) from @emlybelz described how the conference of catholic bishops has now banned NDAs in abuse cases but how some churches and Christian orgs still use them without

Later in 2018, @scotmcknight discussed NDAs after the Bill Hybels sex abuse scandal, noting that often the stronger party is implicated in sin because the whole reason for the NDA is bc they know that something is wrong and they don’t want it

The common understanding of propaganda is that it is intended to brainwash the masses. Supposedly, people get exposed to the same message repeatedly and over time come to believe in whatever nonsense authoritarians want them to believe /1

And yet authoritarians often broadcast silly, unpersuasive propaganda.

Political scientist Haifeng Huang writes that the purpose of propaganda is not to brainwash people, but to instill fear in them /2


When people are bombarded with propaganda everywhere they look, they are reminded of the strength of the regime.

The vast amount of resources authoritarians spend to display their message in every corner of the public square is a costly demonstration of their power /3

In fact, the overt silliness of authoritarian propaganda is part of the point. Propaganda is designed to be silly so that people can instantly recognize it when they see it


Propaganda is intended to instill fear in people, not brainwash them.

The message is: You might not believe in pro-regime values or attitudes. But we will make sure you are too frightened to do anything about it.

There is some valuable analysis in this report, but on the defense front this report is deeply flawed. There are other sections of value in report but, candidly, I don't think it helps us think through critical question of Taiwan defense issues in clear & well-grounded way. 1/


Normally as it might seem churlish to be so critical, but @cfr is so high-profile & the co-authors so distinguished I think it’s key to be clear. If not, people - including in Beijing - could get the wrong idea & this report could do real harm if influential on defense issues. 2/

BLUF: The defense discussion in this report does not engage at the depth needed to add to this critical debate. Accordingly conclusions in report are ill-founded - & in key parts harmful/misleading, esp that US shldnt be prepared defend Taiwan directly (alongside own efforts). 3/

The root of the problem is that report doesn't engage w the real debate on TWN defense issues or, frankly, the facts as knowable in public. Perhaps the most direct proof of this: The citations. There is nothing in the citations to @DeptofDefense China Military Power Report...4/

Nor to vast majority of leading informed sources on this like Ochmanek, the @RANDCorporation Scorecard, @CNAS, etc. This is esp salient b/c co-authors by their own admission have v little insight into contemporary military issues. & both last served in govt in Bush 43. 5/

The kingdom of Sindh was ruled by its last Hindu king Raja Dahir during the 8th century. When Muhammad-bin-Qasim invaded Sindh, he decimated Sindh in his savage bloodlust. The chronicles of his advent are described in the Chachnama.


2/n
The Chachnama describes in detail how the Arabs led by butcher Qasim conquered Sindh. It tells the terrible tale of bravery, treachery, & carnage marking the entry of Islamic conquest of India’s Hindus.


3/n
When Muhammad-bin-Qasim attacked Sindh, Dahir had collected an army of 50,000 horses and marched from Brahamanabad to Rawar to face the invader. Qasim had an army that numbered in the tens of thousands with camels & horses.

4/n
Earlier Arab Alafis - Syeds from Prophet Mohammed’s own family had fled from Mecca with 500 men to Sindh and Raja Dahir had given them asylum. Trusting these Muslims would prove to be the fatal mistake for the downfall of Sindh & pave the way for Islamic invasion.

5/n
On an “auspicious day” in A.D. 711, fixed by astrologers, Mohammed Bin Qasim started for Sindh at the head of the Iraqi, Syrian, and other Arab soldiers. His horses and camels were disguised to look like lions and elephants. Rebel Jats also joined Qasim’s army.

ugh i wanted to do a thread about the wars in Star Wars and how the two outlying wars (the clone wars in the prequels and the cold war/civil war in the sequels) are really weird but i don't feel like it any more.

my first argument is that the Clone Wars were a really complex morally gray moment in Star Wars canon in like, 5 different directions and I'd kind of like to know why Lucas did that.

especially with the direct line that's drawn in the OT with the allegory of WW2 and Vietnam with the rebels being the Vietnamese and the Empire being America. That...doesn't exist in the Clone Wars.

for starters: it's weird it's called the Clone Wars. I get why, because that's what Kenobi calls it in STAR WARS, but the clones are a small facet in the larger story of the war.

the clones basically only exist as a macguffin in AOTC that is...extremely confusing ultimately. Because if you accept that Sidious has this grand master plan to use this war to destabilize the Republic and form an Empire...it's way too complex.

I hate when I learn something new (to me) & stunning about the Jeff Epstein network (h/t MoodyKnowsNada.)

Where to begin?

So our new Secretary of State Anthony Blinken's stepfather, Samuel Pisar, was "longtime lawyer and confidant of...Robert Maxwell," Ghislaine Maxwell's Dad.


"Pisar was one of the last people to speak to Maxwell, by phone, probably an hour before the chairman of Mirror Group Newspapers fell off his luxury yacht the Lady Ghislaine on 5 November, 1991." https://t.co/DAEgchNyTP


OK, so that's just a coincidence. Moving on, Anthony Blinken "attended the prestigious Dalton School in New York City"...wait, what? https://t.co/DnE6AvHmJg

Dalton School...Dalton School...rings a

Oh that's right.

The dad of the U.S. Attorney General under both George W. Bush & Donald Trump, William Barr, was headmaster of the Dalton School.

Donald Barr was also quite a


I'm not going to even mention that Blinken's stepdad Sam Pisar's name was in Epstein's "black book."

Lots of names in that book. I mean, for example, Cuomo, Trump, Clinton, Prince Andrew, Bill Cosby, Woody Allen - all in that book, and their reputations are spotless.

Right, screw it. Here's a thread on *that* FBLive by Alex Cairnie about #Govanhill. Lets do a watch-through shall we? (Mind, I'm a resident of Govanhill, and a sociologist. I'm also 5'3, and a visibly queer woman so if half his claims are true I should be living in terror)

00:30: Welcomes viewers and uses points out that his videos are only getting attention b/c they're 'horrific'. Directs folk to his Youtube page. So already clout hunting.

1:08: "I've been warned to stay out of Govanhill. I'm a marked man" (proceeds to use a beanie as a disguise)

1:30 "Laughing and joking aside, here's somebodys front garden." Proceeds to show litter and claim its thrown from windows and this is 'common'. I know a handful of streets with litter issues like this, but its neither common nor unique to #govanhill and other deprived areas.

2:10 "Don't be under any illusion I'm only showing you the bad bits" - only shows you the bad bits.

3:45: He's had offers of help, but hes said no because hes not responsible for 'anybody elses safety' Good lord.

5:01: "Its not that bad. But its not all good either" -Correct

6:00: TW: child abuse - He starts claiming to have been contacted by a health professional and told about child abuse 'in the area'. Huge ethical issues here as the 'professional' who has 'been in the game a long time' is reporting to Facebook Dude and not authorities.
