Western Digital and IP 78.137.100.54

We have an RX4100 and a DX400 series Sentinel device in two separate networks. Every week I get an IPS hit on 78.137.100.54 for a buffer overflow:

Watchguard IPS Notice

I've ignored this in the past because I couldn't find much information about it. Plus, the IPS is denying it, so I didn't pay much attention to it.

Today, though, I dug a little bit deeper.Turns out 78.137.100.54 is Star Wind, which is a virtual storage software provider (in Germany).

I couldn't find the offending header that was triggering the IPS. We don't track that level of detail in the IPS detection, unfortunately. That would be a nice thing to have.

Why the WD devices are contacting StarWind on a weekly basis is unknown to me. I don't recall any disclosures about that activity when I bought these devices.

We're retiring that RX4100 soon. It's network cards always go offline for no apparent reason. Other IT people have reported a similar experience with the RX4100. That usually happens at night, which is no big deal, but sometimes it happens at the start of the business day. That's happened enough times to warrant immediate retirement.

We've purchased a Synology to replace it. Hopefully the Synology does't make unexpected outbound connections to a German ISV.

Stock Option Debt Income

The 2024 Presidential election has brought out a topic of interest that seems to have been perverted. There is this "Taxing Unrealized Capital Gains" [1] movement that is being falsely attributed to Vice President Harris. Clearly, this is a change in the revenue code that was designed by someone in office long before VP Harris was in office. My money is on Elizabeth Warren and Bernie Sanders. What is this change in the revenue code though? For that you have to understand what Silicon Valley zillionaires are doing with their stock options. Many of these people in this special economic area have huge discounts on stock prices for companies that are not public yet, or are public and can not be sold [2]. To be fair to these holders of equity, banks allow them to finance debt using leverage against those options. If you hold an option that is worth $5M then a bank might lend you a share of that value, thus realizing a debt against the option [3]. This is a fair debt instrument and...

A Self Defeating Race False Narrative

2020 is the year of the pandemic. The SARS-Cov-2 (Covid19) virus has rampaged across the planet infecting 4,893,136 [1] people by May 20, 2020. At this time, of those 4.8M people, 323,256 people have perished from complications that arise from the infection. Arising out of this pandemic has been a narrative about non-white ethnic groups being disproportionately affected by the infection [6,7,8]. A narrative that conditions people to believe that they are perpetually victims only creates a "collective victimhood" [4,5] in that group. This "collective victimhood" costs its members millions in unrealized potential, sends them cowering from social interactions that would otherwise benefit them, and ultimately creates an environment that perpetuates itself. Let's try to dispel that false narrative and deal just with data. I pulled my data from the CDC [9] looking at mortality only. The mortality data from CDC contains per-state mortality rates on a per-infectio...

Number of Primes

Anderson's Theorem (a) The number of primes in [1,n] is no more than 2+floor(n/2). The probability of n being prime when n is not prime is 1/2 - see Dasgupta,Papadimitriou,Vazirani "Algorithms" page 26. Therefore, the E(pi(n)) is n/2. (b) There does not exist another set of adjacent primes other than {1,2,3} 5: 2 + floor(5/2) = 2 + 2 = 4:=> {1,2,3,5} : 4 <= 4 7: 2 + floor(7/2) = 2 + 3 = 5 => {1,2,3,5,7} : 5 <= 5 11: 2 + floor(11/2) = 2 + 5 = 7 => {1,2,3,5,7,11} 6 <= 7 26: 2 + floor(26/2) = 15 => {1,2,3,5,7,11,13,17,19,23} : 10 <= 15 Lagrange's Theorem is Inaccurate Lagrange's theorem about primes states that pi(x) is the number of primes <= x. The pi(x) is approximately x/ln(x). He postulated that the lim of pi(x)/(x/lnx) as x-> infinity was 1. This is incorrect. if the number of primes is bounded by n/2 then refactoring and reducing Lagrange's Theorem results in the lim of ln(x) as x approaches infinity. This is alwa...
