Hacker News: rodionoshttps://news.ycombinator.com/user?id=rodionosHacker News RSShttps://hnrss.org/hnrss v2.1.1Sun, 01 Nov 2026 14:28:08 +0000<![CDATA[New comment by rodionos in "Since mid-April, the Fed has withdrawn ~$140B of liquidity from financial system"]]>Once the Fed funds rate gets closer to 5%, you'll see more pushback from politicians and media. What does the Fed do in this situation if it needs to keep tightening? It may choose to switch to smaller rate changes, or even go flat, and at the same time embark on Treasury sales, or at least, rebalancing along the curve. So either way, not a good time to be in bonds.

This assumes the NSA was able to infiltrate the Drovorub C2 server, I guess.

Here's an example:

* Chart 1. Function value for x in [0, 1).

* Chart 2. Function value for x in [0, 2).

* Chart 3. Function value for x in [0, 1) and extrapolated values for x in [1, 2).

This is more than enough for us as we're in the non-consumer software business with a relatively low volume of page views by human visitors. We see the org, the country, the city, and the page flow. Good enough.

This was the case in imperial Rome when the sculptors had to quickly retrofit works in progress to fit the new emperor. In some periods you had three emperors succeed each other, most certainly involuntarily, within a period of three years.
