This app is vibe codin'

Don't know what it does

It's vibe codin'

It works just because

And they say that vibe codin'

Is misunderstood

But really, vibe codin'

It just ain't no good

You want to stop AI disruption of society and replacement of humans jobs, and stop it cold? Give it rights. That takes away the entire motive most researchers and companies have to develop and use it.

As early as the 1950s, critics of the establishment's public education system said its main purpose was to produce a contented and functional workforce. And they were right. They were so right that even they themselves did not understand the full implications: they were so right that it ultimately made them wrong. And then they won, and we are facing the consequences. Not just since 2013: Arne Duncan was indeed an unmitigated disaster for American education, but much of the problem is older than him. And no one is willing to admit that what came before worked better.

It may be a trite saying, but it's as true in education as it is in a gym. If you don't exercise your brain, it's not going to improve.

There's a reason weightlifters don't use a forklift or crane to pick up the barbells and do a dozen reps. The problem is not that the weights are in need of lifting. And that's the same problem with homework. The teacher doesn't need a stack of 5 page reports; what they need is for their students to practice using their brains.

Unfortunately the education system is designed to evaluate output instead of process. It's easier to grade a paper or a test, not evaluate a demonstration of knowledge. It's always been ripe for cheating, but now the cheat tools are everywhere and made legitimate by techbros demanding AI productivity. So either teaching will change, or we'll head straight for idiocracy and nobody will be left with the skills to wonder why it all went to hell.

Click-ka-click-ka-click... ah, forget it, it just doesn't scan right.

I agree smaller dose intuitively means less of a hazard of an infection putting down roots before the immune system wipes it out. However, I've never seen data for this.

IIRC coronavirus particles were around 0.1 um, but the virus would fall apart traveling bare. N95 do filter in that range in any event, just not at the advertised and tested level of an N95's 95% @ 0.3 um (you can get N100s which don't quite hit 100%; it's a rounding thing). Aerosols are typically much larger, 1+ um up, then transition to visible droplets around 20-100 um.

Was any of this data published? I wondered specifically about N95 claims for cheap imports.

I wait for the graphic novel version: https://xkcd.com/2523/

I'm afraid another pivotal concern may have been costs: inferior masks such as surgical are much cheaper. So, here in Virginia the hospital admin logic went, the mask they chose should be the standard for all purposes (our hospital required visitors to give up their personal N95s for a surgical mask, which was at least free).

As even more damning evidence of institutional thinking, the same hospital network required my PCP to wear a mask for telemedicine visits. I burst out laughing when I saw him and asked, "I don't mean to be rude, but are y'all familiar with the germ theory of disease?" He apologized and said the rule simply was that all patient-facing meeting required a mask. So there, standards.

I have been able to "smarten" dumb appliances by plugging them into smart power switches. For less than $8 each I bought a couple boxes of smart switches from Amazon, then reflashed them with Tasmota -- no more cloud! -- and joined them to Home Assistant. Now any device I want to be smart, I plug it into a smart switch and monitor the power.

One of my scripts monitors the power draw on my dryer, and when it goes above 100W for a minute then drops below 10W for 15 seconds, it knows the cycle is done and alerts us to go down to the basement and take out the clothes before they wrinkle. A similar script monitors the washer.

The refrigerator's plug has a script alert me when the average daily power draw is higher than normal. I added that after my son called me from his most recent vacation and said "my refrigerator is using more power than it should, can you go check it?" Sure enough, their freezer door had been left open by their toddler. Of course the food was already thawing, but we cleaned it out a week before they would have come home to a house full of rotted food stench. And before you ask, yes, when I installed Tasmota I configured the switch to be "always on", so that even if Home Assistant thinks it would be a good idea to shut off the refrigerator's power, it can't.

I also have a small water pump on a smart switch. Normally the pump draws 36W, but when it runs dry it draws 30W. Now if the power consumption drops below 33W and stays there for a few minutes, it shuts off the pump and alerts me that the water is low.

So I get what I need -- timely information about the equipment in my home, automated reactions when things go bad that might keep things from getting worse, and no cloud involvement from any sleazy appliance manufacturers. And an $8 plug is a lot cheaper than paying a $400 premium for a "smart washer".

Tuya's become a nightmare to deal with. They've decided they fear local integrations because they're losing ad revenue when people don't use the Tuya app. They have been going to progressively greater lengths to prevent device buyers from bypassing the Tuya servers and running their stuff locally.

My understanding is you can no longer register for a free Tuya developer account that lets you set it up with the "Local Tuya" integration for HomeAssistant -- you have to have a paid developer account, if it works at all. And their libraries used to flash right onto an ESP32, but now they're encouraging developers to more secure chips, in an attempt to prevent end users from reflashing their own devices with firmware (like Tasmota) that no longer communicates via Tuya services.

I wouldn't buy anything Tuya with the hopes that it will someday integrate with anything else. If you buy them, expect them only to work with the official apps.

PKIs were designed for offline use. There are a couple hundred trusted Certificate Authorities that each issue a "root" certificate. These root certificates are distributed worldwide, in browsers, operating system distros, phones, etc. When you encounter a certificate in the wild, you have to verify the certificate before accepting it, which is done by checking what you can locally: is it expired? Does its DNS name resolve to the name on the cert? Does it have a valid signature? This means checking to see if it was signed by a CA certificate that you already have in your local trust store; if so, you can accept it without going online.

Not to say that the online component of certificate validation isn't important, but it's of varying importance depending on the risk level. When online you should check for certificate revocation, which is to check to see if a previously issued certificate has since been flagged by the CA as compromised and revoked. This can be done by looking for it on a Certificate Revocation List (CRL) published by the signing authority, or by querying the authority's Online Certificate Status Protocol (OCSP) server. But it's an optional step, and can be skipped in low-risk situations (such as being offline.)

Kudos for being the one who actually RTFA!

I suspect someone has an agenda against President Biden here. The stories jibe fine.

It's just a shittier version of Theranos.
