That is a smart optimization but it does make you wonder why were they using a size_t to hold the category (only 3 possible values) in the first place...

It also didn't have memory segmentation, otherwise known as The Worst Thing. The examples in the post are clearly x86-64 running in 64 bit mode. I.e. it's running in flat model... there is no segmentation to worry about.

They claim he was spoofing trades... That's more the domain of HFTs, where you can automate the process, not a lone trader, however sophisticated. They have him in emails literally saying things like "If I keep entering the same

In contrast, GNU grep uses libc’s memchr, which is standard C code with no explicit use of SIMD instructions. However, that C code will be autovectorized to use xmm registers and SIMD instructions, which are half the size of ymm registers.

On that case I think I agree with the Matt Levine take that "Back in September I was pretty sympathetic to DRW and after reading the CFTC's complaint. I'll double down on that.†" I guess we'll see what happens. My o

Do you think when Don Wilson (founder of DRW) was making markets in the pits at the CME in the 80s that he was colluding with anyone is more what I was asking. Does he deserve to be labeled "crooked as a barrel of fishhooks?"

What about all the human market makers that went on to found HFT firms. DRW, GETCO, Jump, Virtu, etc. Bad guys as well?

There are no derivatives here. Jefferies was going to sell bonds backed by the loans. The payments on the loans would effectively flow directly to the bondholders. A derivative (e.g. a CDS) would be more like a side bet between two (possibl

You are thinking about this wrong. The S&P 500 is a capitalization weighted index meaning the larger the market cap the larger the weight. If you constructed a total market index using the same capitalization based weighting scheme, you

I haven't tried obtaining a CCW in Chicago because the idea of wandering around Chicago carrying a gun seems totally ridiculous to me.

BTW, these people problems are the result of Democrat's policies in gun-free cities such as Chicago, St Louis, Oakland and Baltimore. I don't know about the other three cities, but you can concealed carry in Chicago and that has

It's the same problem. Assume my GPS clock is synced to actual GPS. You turn on your spoofer and now my clock sees that the GPS source is running faster or slower than it should be so it falls back to the internal oscillator.

by minimax 10y ago
Any GPS clock you are going to find in NY4 is going to be sufficiently sophisticated to check the GPS signal against its internal oscillator in order to check for validity. It can fall back to the internal oscillator if the GPS time looks b

Because you seem to be trying to establish some equivalence between Anna's circumstances and the author's. I think it's insulting. If I misunderstood the point you were trying to make I apologize.

I wonder if people like Anna moving in also felt the same guilt that the author of this piece does? I didn't care for the article, but this comment is awful and you ought to feel bad about writing it. Did black people moving into an

Comments like these... they just show you have no idea what you're talking about. Investors are perfectly free to trade on the IEX ATS all day long in its current incarnation.
