billsnow··on Bank run on Silicon Valley Bank
It’s not symbolic, it’s literally an insurance company that the banks pay premiums to.
billsnow··on Investigating Logan Paul's biggest scam [video]
Why would it be beneficial for society to filter out people who make poor business decisions? Many of the greatest generals, politicians, scientists, and artists in history were terrible at business and fell for scams many times.
billsnow··on FTX’s balance sheet was bad
Ok fine that’s not what jane street does.
billsnow··on FTX’s balance sheet was bad
That’s not what traditional finance does…
billsnow··on FTX’s balance sheet was bad
He was there for only three years, and at least ignorant about the finer points.
billsnow··on Carbon Language: An experimental successor to C++
Seems neat, but it looks like the major thing is the syntax. Of course c++ syntax is insane and should be updated, but i cant shake the feeling that c++ developers secretly love it. Scanning c++ code for a seasoned c++ developer is like the bushmen of the kalahari scanning the african savanna.
billsnow··on There's been a big rise in monitoring workers at home
What none of these three points are true.
billsnow··on Intel is reducing server chip pricing in attempt to stem the AMD tide
According to who? I checked the edac module for a year on my work machine, and it never detected a single error. I know I'm just one anecdote, but I doubt I'm that lucky.
billsnow··on Intel is reducing server chip pricing in attempt to stem the AMD tide
ECC support is an actual +10-20% cost in materials for the motherboard and DIMM manufacturers. Also, ECC errors are basically non-existent on desktop/laptop workloads. ECC is worth the extra cost in servers, but for desktops and laptops, the market got it right.
billsnow··on Knuth-Morris-Pratt string-searching algorithm: DFA-less version
Oh I have some bad news for you, buddy.
billsnow··on Apple M1 foreshadows Rise of RISC-V
You can already do this. There's a kernel boot parameter called isocpu or something and the kernel will only run on the logical cpus listed. Furthermore, you can isolate your user programs. The general benefit is latency, but there's a theoretical trade-off in scheduling bandwidth. The memory heirarchy will be utilized less efficiently too.
billsnow··on Zoom executive charged with disrupting meetings commemorating Tiananmen Square
yeah that's not the lesson from this
billsnow··on Staff Report on Algorithmic Trading in U.S. Capital Markets [pdf]
Here, here.

Curiously, the commodities markets have always adjusted tick sizes for different contracts so that the dollar value is reasonably consistent (~10 dollars). These are products for which the contract size (in dollars) varies wildly and the quotes are all over the place (anywhere from 9 decimal points to no decimal points).

It makes writing your algos confusing, esp when you start doing inter-commodity spreads, but the business case is so obvious, it really makes you wonder why the equities markets haven't done more.

billsnow··on Nvidia is now worth more than Intel
Well that entirely depended on Intel's so-called process advantages, didn't it?
billsnow··on The War on Upstart Fiber Internet Providers
Laser? Do you have any links for them using lasers? I only see directional antennas (that you can buy on amazon) on their site.
billsnow··on But no, 80-column terminals in 2020 isn't “reasonable” any more
In the post he refers to "wide tabs" which means hard tabs displayed 8 chars long. This has been the standard kernel style since the beginning.
billsnow··on Renaissance Technologies
I think he means that they funnel the income from fees into this "black box" fund and that's what creates the huge returns. My instinct would be that there's no way this would get past auditors, but then again, Madoff got away with cooked books, so it's plausible.
billsnow··on Bounded Integer: Header-only C++ library replaces integers, adds explicit bounds
How long does it take you to code a program if you are being bogged down by such simple problems? Use ints and do bounds checking when it's necessary to do so. Is every single bucket of information a reinvention of types?
billsnow··on Experts cracked laptop of crypto CEO who died with $137M, but the money was gone
Yeah, if only there was a tool for managing 30,000 wallets in a centralized way, then it would be more obvious why decentralization makes the need for regulation moot.
billsnow··on Text Editor Performance Comparison (2016)
No it's the BSD clone from the nineties. Ascii only.
