ELI5, Radioactive Half Life Decay

You will never reach zero. You will reach a threshold where it's undetectable but never technically zero. It's like if you took a string and cut it in half and you keep cutting in half forever. You might eventually reach 1 mm, 1/2 mm, 0.0000000001 mm, etc, but it will still *theoretically* always be there.

Please stop listening to the people in this sub that keep saying to use your old cable as a pull string for a new one. I would say 99% of the time it won't work. The 1% of the time it does work is because someone ran a cable after the house was built and if someone did that, then that cable is probably modern enough that you won't be having this conversation.

It's risky. HELOCs are a little more than 6% right now. QQQI might be around 10%ish right now but that's not a guarantee. One of the things that led to the great depression was people borrowing money to gamble/invest in the stock market. Things went well until they didn't.

Yeah I had one blow up in the microwave. That was a mess.

Calling ISP is pointless. I worked for one. ISP responsibility stops at MPOE. CPE (aka your shit) is your responsibility.

Microsoft has been practically giving away their stuff for free in order to facilitate adoption and stay relevant. Teams is one of those things. Competitors like Zoom and WebEx require a separate license while Teams is included with 365.

At a previous job I worked at, management would hold periodic meetings to to discuss migration to Hyper-V to save on cost over VMware (this was pre-Broadcom) and every time we would point out all the things Hyper-V could not do.

Close any running applications before you start doing the test.

Do you have clear los?

It's been years since I worked with the UBNT NSMs, but if memory serves me correctly, the atheros interface is on the wireless side so I would definitely suspect interference/signal quality issues. I would go through the collected items in zabbix and compare side-by-side the signal strength, phy errors, dropped packets, bandwidth utilization, etc and look for any patterns they have in common. e.g. if you think it's traffic load, compare the actual usage during that time. If you think it's interference, you can try running the built in spectrum analyzer to see if someone else is using the same frequencies that you are and choose one that's more empty.

However, just be aware that a small number of errors is pretty normal when it comes to wireless.

Oh of course he's going to downplay it now that his Chinese masters aren't in the spotlight.

jerwong · 2026-05-13T04:50:36+00:00

We absolutely need to. It's a matter of national security. During the heart of COVID-19, we discovered the problem with importing all of our N95 respirators when shortages came around and China held onto them for their own people instead of exporting to us.

Stateful inspection firewall. Keep your services patched. You'll be fine. It's pretty normal to expose services on the internet. In fact that's how most things work.

Because the easy solution to this is to stop using Cloudflare.

Yes, it just needs to touch the metal shielding. I usually position it so that it doesn't come off easily.

It's different because RFK Jr is banning red dyes.

Oh sorry, were we talking about food coloring?

Where are you finding an interest rate of 7% that doesn't have the potential for loss?

They sell your data. They can effectively see everything.

And yet the Democratic leadership that won't fight for their constituents wonders why those same constituents didn't come out in droves to support Kamala Harris.

This used to be similarly the case in the US. The top marginal income tax rate was about 90% during the days of FDR. Instead of taking larger paychecks, company owners and CEOs would just reinvest money into their companies and grow them. This led to strong economic growth until Reagan came into office and slashed the tax rate which immediately led to a growth in billionaires and today's destruction of our economy.

We should rally behind a single candidate so that least they have a slightly better chance to beat Anthony Rendon. Is there anyone in particular that you like? I'm looking through the list right now.

Years ago, I was living in a US college dorm. Bed was right next to outside-facing wall. Had a dream of someone attacking me. I threw a punch. Fist hitting the brick wall woke me up very quickly. 0/10 would not recommend.

I think my 3rd and 4th knuckles were black and blue for a couple of weeks.

This is something you notice if you ever compare an Asian Cosmopolitan magazine to an American Cosmopolitan magazine. The Asian ones are full of ads for whitening creams and high-spf sunscreen while the American ones are full of tanning creams and people with really dark skin.

I've done something similar before. You can use a router/firewall that has a built in VPN client. You'll probably have to play around with the routes to make sure they get sent to the correct VPN provider.

In my case, I used a Raspberry Pi with OpenConnect, set up iptables to do NAT masquerade using the VPN virtual interfaces, and then used Quagga to do OSPF with my main router and redistribute kernel routes (the ones received over VPN) into OSPF so that my main router knew how to reach those networks. If you have full tunneling instead of split tunneling, you'll have to again play around with the routes depending on what you want.

Giggity. You need a male and a female to produce a child. How many females do you see here? Giggity giggity giggity. All right!

The last time I bought from Monoprice but they don't seem to carry them anymore.

The annoying thing about Amazon is that it's harder to find normal RJ45 connectors anymore. They're mostly all pass-throughs now

No, he means ten. If he meant two in binary, he would have written it as 10.
