  • I’m not saying it is no big deal to regularly expose one’s self to it.

    I know about how small of an amount can be smelled from building a power supply for a UV light, making mistakes, and yet still smelling the thing. It was back driving some circuit block that shouldn’t have been enough power to do anything, there was no visible effect, but I could still smell the faint smell of O3. Even with a tiny bulb, the smell is nearly instantaneous when the light is powered. Running one around anything that can rust is a bad idea. It is almost as bad as working with hydrochloric acid and hydrogen peroxide as enchants; everything goes super rusty fast. I don’t get exposed to it regularly, so I’m not worried. Most hotel rooms smell pretty strongly of O3 in the many I have stayed in and that is probably the most that the average person gets exposed for any extended length of time. The alternative is probably worse, but still people don’t worry about that one too much.



  • It is 6w before power supply losses and then a tube that is likely under 20% efficient. The primary thing that gets you with welding is the fraction of a second before an auto darkening lens activates. It is a tiny amount of time, but it adds up. Or all those times you accidentally touch the tungsten to the pool with tig. Welding has a wide spectrum, but it is the power that matters most here. The frequency and power are two separate and unrelated things. Like your microwave and WiFi are both 2.4 GHz machines. Your WiFi in your home router is limited to 100 milliwatts and is totally harmless. Your microwave needs a Faraday cage built in to avoid cooking you from the inside out because it is likely around 1500 watts. At 220nm the frequency doesn’t pass through skin or eye fluid and the power output of the light is low. Seriously, try getting into things like telescope filters where you’re trying to isolate certain frequencies. It is challenging at these frequencies to find anything that is transparent. Of all of my science books, my optics handbook is by far the largest and hardest for me to follow. That isn’t saying much, but I have built my own telescope electronics and eyepieces, along with hobby electronics, designing and etching circuit boards and photolithography using various UV lights I have built. Six watts is nothing major. I would be more concerned about how limited of an area one light can cover.






  • I don’t use perplexity, but AI is generally 60-80% effective with a larger than average open weights off line model running on your own hardware.

    DDG offers the ability to use some of these. I use a modified Mistral model still, even though its base model(s) are Llama 2. Llama 3 can be better in some respects but it has terrible alignment bias. The primary entity in the underlying model structure is idiotic in alignment strength and incapable of reason with edge cases like creative writing for SciFi futurism. The alignment bleeds over. If you get on DDG and use the Anthropic Mixtral 8×7b, it is pretty good. The thing with models is to not talk to them like humans. Everything must be explicitly described. Humans make a lot of implied context in general where we assume people understand what we are talking about. Talking to an AI is like appearing in court before a judge; every word matters. The LLM is basically a reflection of all of human language too. If the majority of humans are wrong about something, so is the AI.

    If you ask something simple like just a question, you’re not going to get very far into what the model knows. Models have very limited scope of focus. If you do not build prompt momentum into the space by describing a lot of details, the scope of focus is large but the depth is shallow. The more you build up momentum by describing what you are asking in detail, the more it narrows the scope and deeper connections can be made.

    It is hard to tell what a model really knows unless you can observe the perplexity output. This is more advanced, but the perplexity score for each generated token is how you infer that the model does not know something.

    Search sucks because it is a monopoly. There are only 2 relevant web crawlers m$ and the goo. All search queries go through these either directly or indirectly. No search provider is deterministic any more. Your results are uniquely packaged to manipulate you. They are also obfuscated to block others from using them for training better or competitive models. Then there is the anti trust US government case and all of that which makes obfuscating one’s market position to push people onto other platforms temporarily, their best path forward. - criminal manipulators are going to manipulate.




  • This, and lay out the details like ELI5 and as an unemotional objective thing with detail.

    I have received many flags to sort out that take more than a few minutes to figure out the tone and meaning. I strongly believe people have a right to be stupid, wrong, a bit rude, or to have a bad day. I need to know exactly why the comment is more than this in a well laid out fashion. If you think it is a pattern with the individual, prove it. If some subtle phrase carries more meaning than I may realize, say so. I want to make people feel welcome on all fronts with a Hippocratic framework of “first, do no harm.” At the same time, a visible mod is a bad mod. I will read every detail. I will give the benefit of the doubt in every possible case. I won’t be passive to bigotry, but I will allow an asshole that does no harm. I’m but one insignificant mod. I care a whole lot more as a person, but I act conservatively as a mod. When flagging something imagine the person on the other end is working on some big project, stopping their day, and taking a half hour to sort out the details, thinking them through, and taking action. It usually takes me longer to shift gears and do this in practice. I’ll usually send a message explaining why I did or did not do anything as well.


  • If you run a whitelist firewall, you never see CAPTCHA’s. The vast majority on the internet have nothing to do with the website you’re visiting. When the website cannot redirect you to the CAPTCHA host site, it just continues on to the intended destination. The only way I ever see a CAPTCHA is if it is hosted on the same server as the site I am trying to visit, and that is very nearly never. I bet the vast majority of them are actually some advertiser collecting more data to mine in addition to whatever fingerprinting they can collect. Ads only work by opening a hidden frame that is basically another browser tab where you then visit the ad server’s website. This is no different than visiting them in a browser tab. They can access everything available to fingerprint. If you’re using anything Google controls that means they know everything about you down to how dirty your underwear is right now. /s÷2


  • I have an HP laser printer from like 1992, before they turned to US=Privateers; rest-of-the-world=criminal pirates. HP died as a company when they spun off Agilent/Keysight as test equipment and continued the branding for contract manufactured consumer garbage. HP does not make anything. They market, place stickers on what others manufacture, and create ponzi scheme-like extortion scams, as the shriveled shell of a dying husk disconnected completely from their now long irrelevant past.



  • Amazon’s pricing I not deterministic. You were likely tracked and information collected to know this was a key item for you. Amazon will market loss leaders to you in an attempt to get you to default to buying on Amazon.

    As a former Buyer for a chain of retail stores, the loss leader is effective marketing. I sell you a popular item at or below my typical cost because statistically, a large percentage of customers are making a special trip to my store to buy that product and will make additional purchases at margin. On the wholesale Buying side, these are tools to get past bulk buying tier discounts for seasonal ordering with smaller scale retail.

    Amazon is using a convoluted front end system of overlapping product categories and a supposed multi seller listings (despite collectivized logistics and warehousing) on the website you see. This is how they perform price fixing where you do not see honest or straight forward determinism. When you repurchase that same item later without making comparisons, the seller will shuffle so that a higher price is presented.

    If you have a well isolated network where device history for social media and internet browsing is totally partitioned from e-commerce you’ll likely see even more of the scam. If you see anyone online show the search results and pricing on Amazon, then try to replicate those search results and product price on a device that is totally partitioned from your viewing of the item/price elsewhere, you’re likely to find it is not possible. If you then go back to the original device and do the same, you’ll magically find the same product and lower price. It is a scam market. This is why they are collecting and paying for all that data about you. We are in an age when automated individual targeting and manipulation is possible and happening. This is why data mining stalkerware is insidious. Scam markets are only the tip of the iceberg and what can be uncovered if you go looking for it. Anyone that has done database or logistics management should have major red flags flying when looking at how Amazon’s website is setup. The front end is absolutely untenable garbage for effective logistics. The only reason it is convoluted and search results are terrible is because it is a price fixing scam. The logistical efficiency proves that there is no connection between the front and back end of the site.


  • From me specifically? When I was first disabled, I still used most corporate social media and stalkerware. In an isolated environment like I’ve been stuck in for a long time, it became clear that the user retention through suggested content manipulation algorithms and notifications were not able to compensate for someone in my condition and availability. What had always seemed like minor manipulative annoyances, became obvious manipulative annoyances. I started to see how the interruptions had altered my behavior. There were some interests I sought out on my own, but many pointless and frivolous distractions and things or projects I bought into because I felt like I had found or discovered something on the internet. Over the years of isolation, I can more clearly see the pattern of what was really my interests and what was suggested to me in manipulative contexts. One of the prime ways it happens is when I’m frustrated with something I’m working on and getting no where. Suddenly I get a seemingly unrelated suggestion or start getting what seem like random notifications. Those seem to target my emotional state specifically in a targeted way to tended to push me into new things or areas I didn’t really expect or want to pursue prior.

    I could write off that kind of thing. I became alarmed most around 2018 when Dave Jones showed some search results on YT and was talking about them. I could not reproduce his search or even find the reference at all. A week or so later, it came up. I had it happen again a couple of months later. No matter what or how I searched I could not find the correct results. It is because google was being paid to funnel me into another website some imbeciles thought was related to my search results but the website in question is a garbage third party referral linking middleman. When they showed up in my search results, I couldn’t find anything I was looking for. They were quite literally paying so that I could not find what I needed. It wasn’t ads placement. It the top 20 pages of google, the results were simply not present at all for what I was looking for. In this situation, I could empirically check and see what was happening. Any company that can do such a thing with what I can see should never be trusted with what I cannot see. That type of manipulation is world changing and extremely dangerous. There are only two relevant web crawlers by size, Microsoft and Google. Every search provider goes through these two crawlers either directly or indirectly. When google failed to work, so did DDG, Bing, and most of the rest. At the time, Yandex still worked.

    Since I have offline independent AI running, I’ve been able to test this a bit further. If I start searching for certain niche products in a search engine I will get steered in bad manipulative directions. I do not fit the typical mold for the scope of experience and information I know about going back over two decades ago. When I search for something commercial and industry niche specific, I’ve seen many times when relevant products and information are obfuscated as I am steered to consumer land garbage due to what I shouldn’t know. These are situations where I may have forgotten some brand name, but when searching for all of its relevant properties and use cases, the things never come up in search results. I can chat about the product with a decent AI for a few sentences and it gives me the answer. After I plug that into search results, suddenly I start seeing all kinds of related products in other places popping up like it is some kind of organic thing. It isn’t limited to search results either, it was YT, Amazon, eBay, Etsy, and even reddit I noticed similar anomalies. If this kind of connection works in one direction, it must work in both directions, meaning my information bubble is influenced directly by all corporate platforms. It makes me question what interests and ideas are truly my own. I primarily find it deeply offensive that, as a citizen, any corporate shit can cause me to question my informed reality in such a way. Any stranger that asks you to trust them, is nothing more than a thief and con. They are an irresponsible gatekeeper. That is the prima issue.
