The advantage of far UVC over other UV air cleaning solutions is that it doesn't need to be ducted. This means that you can kill microbes right when they leave someone's mouth - you don't need to wait for them to be sucked through an air handler.
I'm curious if plastics embrittlement is a problem with Far-UVC. I recently was putting a large evaporative humidifier [1] through its paces for someone to get my opinion, and a challenge was that you had to clean the water tank that was the foundation of the unit fairly frequently (every few days). I provided feedback to the manufacturer that a far UVC bulb in the tank might be useful for reducing cleaning intervals.
For use cases where the emissions are contained (HVAC, water tanks, etc), I think it's a slam dunk from an electronic antiseptic perspective. UV is somewhat common in water filtration today, but perhaps an improvement is possible if these bulbs last longer than existing UV solutions.
(I do not recommend the humidifier by the way, simply too much work to keep the water tank and the evaporation panels clean, I recommend an ultrasonic version instead)
This is a study of the Ushio Care222 unit, but its underlying physics is the same as any other KrCl excimer lamp, so its pretty implausible for other KrCl lamps to exhibit spectral drift when this one doesn't.
The spectrum does change a bit over time--it actually gets less dangerous. But it's a very slight difference.
So different hardware, a clinical unit designed for thousands of hours.
Vs a very likely Shenzen unit that a teeny tiny group is selling on a basic website. And, you can make zero claims on whether a light spectrum of a led will go up or down over time despite one example. Amplifiers/voltages, coatings wearing down, oxide layers in diodes breaking down, etc.
I'm not sure what you mean by clinical unit--the ushio care222 is the longest lasting KrCl emitter I'm aware of, but as all bulbs age, they tend to degrade just by losing output, not by spectral shifting.
Basically everyone in far-UVC is a teeny tiny group selling lamps on basic websites, even those who source care222 emitters from USHIO. It's not a big industry!
We don't source our KrCl bulbs from Shenzen, but not for this reason. Yes, that's true about LEDs, but the physics of LEDs and excimer bulbs are different. Excimer spectra don't smoothly shift the way LED spectra do. Excimer spectra have characteristic peaks based on the energy levels of the possible gas molecule species present in the filler gas. The main change over time is the gradual reduction of the 259nm Cl2* peak, which is the main peak of concern--so it fails gracefully.
Another possibility is the degradation of the dichroic filter coating under thermal stress--but I've only ever observed this in diffused units, none where the filtered glass is open to the air, and that will happen even on an Ushio bulb.
Nukit is our competitor but I doubt very much that any concerning spectral shift will take place over the course of the lifetime of their lamp.
So… you can’t prove that the unit will not shift wavelength into a harmful range. However, I can prove that by not subjecting myself any others to claimed-harmless light that I can prove it will not become be realized to be harmful.
Cool! You missed peak covid hysteria. But, there are people that will never recover/realize. Like the type of lunatic that would subject everyone to one of these for a thanksgiving dinner in 2025.
Shrug. Nothing is 'harmless', including far-uv. Going outside in the sunshine isn't harmless. The stove in your kitchen isn't harmless. Can you prove your stove isn't going to explode some day and kill you? No, but you don't expect it to, in part because it complies with consensus product safety standards--germicidal UV products have their own standard, UL8802.
Far-uv is relatively new tech so it's reasonable to be wary, but I'm persuaded on the merits of evidence. Viruses definitely aren't harmless, and I'd rather not be catching random bugs on the regular if I can avoid it, or worry about my grandma catching flu in the hospital. Everyone has to make reasonable tradeoffs about risks and benefits.
Nah--use 254nm for that. It's a standard thing, if it's contained in a duct it doesn't need to be fancypants human-safe 222nm.
Ducting it kills most of the effectiveness though--now you have to move air through your ducts in order to treat it, so you only get as much treatment as you move air--usually not very fast or else it would be loud and annoying. You can move it faster, but then you need more UV since the faster-moving air won't be exposed for as long. Honestly, upgrade to a MERV-13 filter before thinking about residential in-duct UV
In-room UV is a different story--since it exposes all room air, pathogens start getting inactivated as soon as they're exhaled. The whole room becomes a disinfection reactor.
A ducted system seems like it kills a lot of the pros of this system compared to just putting an (effective, i.e. merv-13+) air filter in the ducted system to catch the viruses. And also other things that are bad for you like particles small enough to get where they shouldn't in your lungs.
the article talked about how the sendgrid accounts are real, and presume compromised.
I suspect that once the sendgrid account is compromised, they then send out these phishing emails, hoping to compromise _other_ sendgrid accounts to look for password overlap and/or keep the flow going.
I envision that it does not matter, because this is a tactic that would 1) be available to all, and 2) it gives up your vote for someone of your own party, thereby weakening your own position. It's self regulating.
Can't they do that now? If I think my chosen primary guy is winning in a landslide I could just register for another party I don't like and vote for someone who I think is easier to beat.
You would still forfeit the ability to vote in your primary though. I do think there are people that do this, but most people want to vote in their primary regardless of whether it's a landslide.
100% right. I buy lots of Japanese cookbooks secondhand. I found an Okinawa cook book for $8. When I received it, it was clear the author was just a content farmer pumping out various recipe books with copied online recipes. Once I looked up their name I saw hundreds of books across cooking baking etc. there was no way they even tried all of the recipes.
So yes, review and “narrative voice” will be more valuable than ever.
The bytehosting deal is good too! Oh btw lowendbox has a forum called lowendtalk where hosting providers etc. talk as well and show deals etc. and I got part of the community (you need to register and be verified manually but it wasn't hard)
Lowendbox is amazing. Glad we are talking about it as I recently joined it and the community's really supportive and honestly feels more so in the sharing spirit and I even talked about why people use lowendhosts etc. and got some pretty good answers imo
Although do be beware to stay away as there are some hosters which end up going completely down. So go with someone reputable as well and there is whole lore beneath in this forum :)
Racknerd,dedirock are usually recommended, I recommend https://serverdeals.cc/ etc. I have a list which I can recommend after being in the community for some time and here's some websites which I recommend for suggestions
Honestly I still recommend hetzner tho because these are some really really good deals but hetzner just has this reputation of more stability and I jsut have more faith in hetzner and its a "good enough" option imo and there are even some lowendhosts who kind of do share the fact that hetzner is very price competitive.
I personally had gotten a 2$/month 1TB vps hosting (yeah didn't really end up using it much aside from the shock factor/running yabs on it)
and also I got a 3 month 8bucks deal with netcup using their vouchers and everything to get 8 gigs of ram 4vcpus etc and honestly this was the best deal I ever saw but I will have to pay 5 bucks I guess after the 3 months end.
Most of it is remaining idle tho :< Are there any services I can run for the benefit of humanity (like running some self hosted services that can help anybody out there or smth?)
Let me know if you have any questions! I might be able to help you as I was active on lowendtalk till quite recently
I'm on Hetzner as well; migrated from DigitalOcean. They are stable, but they got a bit of bad reputation, since they were hacked at least 2 times already [0] [1]. Stable != Secure.
How did these came to existence? Most of these offerings look basically identical. Is it ran by the same guy behind, or is it like a get rich quick network business stuff?
Some of these are resellers. Big provider sells them a package of 10-1000 VPSs and they set up websites to sell them to you. But you can also find lots of direct deals as well. BuyVM famously has their $15/year deal on a 1GB VPS. You can also often find dedicated servers for like $25/month. I recently bought a $75 lifetime deal on some email hosting for up to 25 domains and I think 250GB storage. Great for some secondary domains and such that I use. There are some real gems out there and you should see their Black Friday threads. Kind of a wild place.
There are lots of even cheaper deals than buyvm usually with racknerd and dedirock. Black friday deals are absolutely amazing but always go with someone a bit more reputed and Buyvm's an amazing choice too although they would be considered "pricey" in comparison to someone (just a few $'s) (I have joined their discord server)
I think racknerd recently did a 6.85$ or similar deal but the point of these deals become is that they become insanely overprovisioned and it becomes a showpiece of sorts "look what deal I got ;P" kinda not sure.
I think another fascinating deal about lowendtalk is that man those people have this faith in small hosting providers and giving chances to them etc. hoping that they become big as well. There are very few places like lowendtalk on the internet. I find a lot of similarities with the hackernews culture although more focused on deals/hosting although its definitely more casual than hackernews.
The weird thing is that it seems like some people are almost addicted to buying these boxes and I am not sure if the use cases. It almost has a feeling of gambling.
I used to get boxes from there for a specific product I had (ability to ping from multiple places around the globe to see what your latency was like) and one provider did burn me but the rest were pretty great.
I just wish more of them provided a proper native IPv6 stack. Still can’t understand why this isn’t standard for all.
> The weird thing is that it seems like some people are almost addicted to buying these boxes and I am not sure if the use cases. It almost has a feeling of gambling.
Oh boy I had thought about this too. There are only quite a few uses of the completely cheap one. Perhaps for the chinese people, it acts as a VPN
Like I thought about the use cases and they were hard for me to find when you consider all the "free" stuff that's launched too. I think to me, some aspects of lowend are for the novelty factor (oh a 2$ 1TB server sign me up!) and what ends up happening is that I didn't really use the storage much so my opinion was nice whereas someone else who used it said that, it's a bad deal
You are right about this though, but still its just fascinating to find the deals and then like the fact is, they are still pretty small and you can just go talk to them and I think this customization and more discussion (hey does your product allow my usecase) etc. are some few reason
I once asked on the forum why they aren't using hetzner,upcloud etc. and someone replied with the fact that they want to make the small one win.
I don't think its completely gambling but you may end up buying something that you don't need much (I ended up with a netcup 8 gig server I guess) in a similar way. But now I kind of know that beating hetzner,ovh, (upcloud's more expensive) is possible perhaps but that if you want ton of servers fast and cheap, there is a possibility but I might still recommend companies like hetzner,ovh,upcloud etc. for any professional use, its just I would be thrown less under the bus as compared to if I have somebody idk set up in dedirock
One of the reasons why I stopped frequenting lowendtalk, might go next black friday perhaps but I don't even know, like there are tons of services now which can offer vm's cheap and fast and just similar to what you might buy from that. There are tons of these I use so I don't really know if buying cheap servers might make sense
One of the reasons I (liked?) the idea of buying cheap servers is that one can always scale when needed and they could then use something like these lowendproviders instead of vercel who initially might be free but then is super expensive. But I think that we are seeing some options which are free but not gonna be super expensive or that expensive perhaps.
The thing is, to me, its nice knowing a place like lowendtalk exists. I might go into its rabbit hole again or not I guess but I don't really know.
There's some commercial software to sell/resell VPS, etc that some of these outfits use.
And it's pretty much a commodity business, so things are going to tend to look similar. If you're buying $5/month VPS, you don't want to pay for a lot of fluff. A lot of these are small time local hosters in a single location, but that's usually all you need for a small site.
WHMCS is probably the easiest batteries-included tool for the job, giving billing, management, and a customer support portal. These could be unbundled or reinvented but for your average hosting company there's no point in doing so.
To be honest there is one instance that i know of where what ends up happening is that colocrossing a major vps provider does end up doing something like this (they used to be hosters/owners???? of lowendtalk/lowendbox)
Now another aspect is that the hosting economy is very mutual, they all start out somewhere and they are usually friendly towards each other. Most Hosting providers start out by either using reseller service directly or by colocating or by reselling dedicated servers which can be themselves of other providers
I don't know but the community is both cut throat and chill at the same time. It's strange to point this phenomenon but I think my point of their friendliness is something which depends and I don't know much about it but I once asked people on lowendtalk if I wanted to create a cloud provider myself and I got some responses and they were friendly so I am basing it off of that
Another aspect is that the market has already raced to the bottom super hard. Hetzner/OVH are really cheap, so to get even cheaper, you kinda have to be in the same pricing range I guess
Fun or not so fun fact but do you know that there have been cases of lowendbox providers to actually go shut down because they take these completely no profitable sense deal and actually lose money sometimes. VeloxMedia is a recent example of that and there is still controversy surrounding it.
There is also the fact that the scam industry in this department works as such:
Rent a really big server with lots of cores for a few months
Sell them unreasonably in LET for the year pricing or more
Then sell the company/be unable to provide/etc.
these I think are called as deadpools in the community.
Also regarding your comment behind same guy, there are sometimes family relations between people
as an example, racknerd I think is owned by the stepson of the owner of colocrossing and they I think using colocrossing themselves.
These have their own little drama stories and I think this is just the tip of iceberg as I just joined recently and probably digging through old archives.
Eng Director here: 100% True. And I'll take it a step further:
> Ask this: “How does a project go from an idea to a ticket? Specifically, at what stage are engineers brought into the conversation; when the problem is identified, or after the solution has already been decided?”
The root of this question is great. The way it's phrased would be a flag for me.
I'd coach someone to ask it this way: "Can you tell me about how bugs and feature requests go from known to implemented/deployed? I want to know how it maps to my previous experiences/workflows"
This is the same question effectively. You will get your answer, and can ask a clarifying follow up if needed.
Can also vouch for this ansible script. I just updated a very outdated homeserver, postgres, and switched from nginx to traefik, and it was extremely painless. I was dreading it, but it worked amazingly. I donated to the author yesterday because of how well it went.
It's worse than that. It's people generating a moral panic so they can retroactively declare something to be crimethink and then use that as a weapon against anyone who disagrees with them by trawling through their history. In which case it's not a matter of standing by it because mobs aren't interested in context or nuance.
Society's defense against this should be that we don't use mobs to punish people for saying things we disagree with and anybody who attempts to do that gets laughed off the stage. Because as soon as that's not what happens, the public discourse gets marred by self-censorship until enough time passes with it not happening that people stop expecting it to and thereby stop worrying that they can't know what's going to be declared an offense tomorrow.
But now that it has happened recently, the only way to get it back in the short term is to have people posting under pseudonyms.
The problem is not people criticizing ideas. The problem is people attacking other people for saying things they don't like, trying to get them fired, etc.
Attack their arguments, not their family, employer, etc.
I mean, you keep repeating the idea that "some people" shouldn't be allowed to use their speech but DHH can use his speech.
You can't have it both ways, either DHH is free to speak his mind on any subject he chooses, and so is everyone else, or nobody is actually free to speak.
For people not familiar with Japanese, finding any info about a Japanese-language game can be a pain. They may have a Japanese representation, an official romanized name, a community romanized name using a different system… plus may also go by an outright English-language name, in some circles, which may (or may not) overlap with the name of an English-language port (if it exists). Then consider that some games have pretty extreme and confusing name variants in various editions or on different platforms, and those may go by different names in different contexts.
You can see the same game go by three different names on a community forum, Wikipedia, and a catalogue of games + md5sums for a system (you might think the md5sum could act as a Rosetta Stone here… but less so than you’d think, especially in the specific context of an English speaker and Japanese games, as you sometimes need some specific, old, oddball and slightly-broken dump of a game to get the one a particular English patch requires… and god knows what name you’ll find that under, but probably not the same md5sum as a clean dump)
The only bright spot in this is that if you can find a Japanese game on Wikipedia the very first superscript-citation almost always lists the official Japanese title in Japanese script on hover. That’s a life saver. (Presumably all of this is easier if you know at least some Japanese)
Though after I posted my comment I realized they mean they’re switching to another existing system (which I think is already widely used in gaming circles? Not sure though) which isn’t so bad. At least it’s not another one being added to the mix.
Even with official names of media you can get stuck.
Consider 彼氏彼女の事情[1]. The Japanese name is the same for the Manga and Anime, but the official names for the US localization of each are different (the manga went with a romanization of an abbreviation of the Japanese name Kare Kano while the Anime went with a translation of the full name His and Her Circumstances.
終末何してますか？忙しいですか？救ってもらっていいですか？ has an "English" title on it's Japanese cover beside the Japanese one "Do you have what THE END? Are you busy? Shall you save XXX?". I'm guessing the author did it themselves. The capitalisation on THE END is presumably supposed to reflect on 終末 (shuumatsu - the end [often used for apocalypses etc]) punning on 週末 (shuumatsu - weekend) and the XXX is because the Japanese title gets to omit the subject and English can't.
Needless to say, the official English translations didn't keep that title, going with "What are you doing at the end of the world? Are you busy? Will you save us?"
