Which employees get hired with an offer of 1% equity that is still 1% at the time of an IPO or (non-acquihire) acquisition? Snap, a prominent IPO from this year, had 6-8 rounds after the $10M valuation this article simulates.

So if a register overflows (and is truncated) "twice" by the same element before the base register (B) is increased, then after B is increased, the overflowing register is not increased and so appears not to have overflowed. On th

I suspect you are right that HLL+TC will be more accurate. Based on Figure 5 vs. Figure 1 in the Ertl paper, I think Ert's method improves HLL estimation for low cardialities and for very high cardinalities, but not for the region wher

HLL is a space/accuracy tradeoff. If you trim HLL to use the same space as if you were using HLL+TailCut but use the Ertl method for estimating cardinalities, which is more accurate: Ertl with a smaller `m` or HLL+TailCut with a larger

While I agree with your essential point about #1, I think we agree for different reasons. UBSan is a set of run-time checks and has low compile-time cost. The example function you give, f, would be complained about if you passed it INT_MAX,

Two other ways of checking integer bound invariants: 1. Undefined behavior sanitizer, which checks integer overflows at run-time, like INT_MAX + 1. Can optionally check other invariants; see https://gcc.gnu.org/onlinedocs&#x

As you may be know, CIA/JSOC statements about the people they kill are often complete fabrications. For example, for years they classified any military-age male killed in a drone strike as a combatant. This included even if the the CIA
