| Glitch in gaming PC network card - 05/11/2026 02:25 PM EDT |
| My Gigabyte gaming motherboard has a 2.5G ethernet port. Occasionally all ethernet cards would stop working. The cause was web site verification on Cloudflare when 1.1.1.1 CloudFlare DNS is used. The solution was to disable some of the TCP/UDP offloading features. Changing the DNS from 1.1.1.1 to 8.8.8.8 (Google) or 9.9.9.9 also worked. According to the Claude AI bot, Cloudflare uses WebSockets and QUIC/HTTP3 during verification which can cause a NIC driver crash. A reboot was required to get it working again. WiFi continued to work after the crash. It reminded me of the OOB (Out of Band) glitch on dial-up in the late 90s. |

The web server code has been upgraded after about 10 years to fix many of the links/apps no longer work. It allows me to test out new versions of web software/scripts and try out ideas that can be used on other projects. |

| Sales tax max - 11/09/2014 12:00 AM EST |
|
How many times can a dollar be spent until it's completely converted into tax? In New Jersey, sales tax is 7%. This calculation doesn't include income tax, which works much faster.
Code used $taxCalc = array();
$salesTaxRate = 0.07;
$payment = 1.00;
for($i=0; $i<pow(2,32); $i++){
$taxCalc[] = pow($payment-$salesTaxRate, $i);
if(number_format($taxCalc[$i],2)=="0.00")
break;
}
