You have it backwards, it cannot work the way you describe, that's practically impossible. A manufacturer creates a device they believe will fit a significant proportion of faces. They then submit that device for standards testing which will verify the device meets necessary standards for filtration, oil resistance, and quality of function. These standards only broadly account for fitment though. Only individual fitment by a specialist can do this, and only for that individual. Furthermore technically there's no such thing as an N95 mask, or rather that description is too vague to define a specific product. When we commonly say "N95 Mask" we actually mean N95 Rated Fitted Respirator. Though even that can be confounding as the following ratings: N99 N100 R95 R99 R100 P95 P99 P100 Can also be made in a form factor visually identical to what people think when they hear "N95 mask" Additionally this rating system exists outside of masks. Here is an N95 cartridge filter https://www.3mcanada.ca/3M/en_CA/p/d/v000057509/ And the device it is used in https://www.3mcanada.ca/3M/en_CA/p/d/v000093583/ Razer purchased an off the shelf N95 filters and integrated it into Zephyr, there is no false advertising with that product, the consumer understanding is what is incorrect. The Zephyr does provide N95 filtration, the actual controversy is a matter of fitment, not filtration. However no manufacturer can guarantee fitment making this standard utterly bad faith to apply to this product, which they don't even call it a respirator in the first place. That being said, it's entirely possible the internal function is leaky and therefore problematic and worthy of refund.

So the general public doesn't have a clue what N95 means, but basically after the widely public respiratory issues from the 9/11 Twin Towers cleanup industries outside the medial industry got specific about covering their liabilities for PPE they issue their employees. Except, only sort of. N95 only rates the filter itself, you could make an N95 rated surgical style mask, because even though it's leaky on the edges the filter is still N95. None the less the term N95 entered common parlance as a result. But what is N95? Well this is part of the USA National Institute for Occupational Safety and Health (NIOSH) which created a standard for respiratory air filters. This standard is in two parts, letter and number. The letter rates the oil and other solvent resistance going from N which could basically stand for "none" followed by R, and P is the highest. Fell free to search R95 and P95 masks as they do exist and should be used in workplaces with oils and solvents including kitchens, how many food service workers such as line cooks aren't being provided R95 respirators? The number portion is more obviously understood. Simply it's the percentage of particles able to pass through the filter under NIOSH's testing parameters. NIOSH again provides 3 tiers; 95, 99, 100(99.97%). So it should be now noted that N95 is actually the lowest possible rating, and is definitely not the "gold standard," Rather it's the 'cheapest possible that employers are not as liable, because they have provided a device with a standardized rating' standard Side note: KN-95 is not a NIOSH rating, it's a Chinese copy of the NIOSH standard that basically mirrors the testing procedure for N95. KN-95 does integrate a facial leakage test, though I generally feel this is largely pointless as nobody's face is the same shape. NIOSH does not do facial leakage testing, and their designations do not mean anything for leakage protection. This makes even more sense when you realize they use the same designation for cartridge type filters, you cannot directly wear a cartridge. When the general public says "N95 mask" they are actually referring to a Fitted Respirator. With understanding of what the N95 rating defines, I have full confidence the filters inside the Razer Zephyr are rated at N95. Now the Zephyr is not marketed as a Respirator, instead it is a "Wearable Air Purifier." Since this controversy they have also added "(THIS IS NOT A N95 MASK/RESPIRATOR)" to the webpage, which is funny but true since the Zephyr form factor really doesn't fit what we think of for breathing mask. Yet still integrates N95 filters. While the term "purifier' does seem to have some meaning in water filtration, in air filtration this term seems to be loosely defined. In the case of the Zephyr the use of N95 filters would seem to be a good faith effort towards their claim. Though I would argue that the filter housing itself must provide a quality seal to prevent filter bypass. I do not know if the Zephyr achieves this, and IMO the product should be recalled if it cannot. Let's be clear about the standards; legally a respirator must be certified by a standards body such as ANSI, CSA, or CEN. Obviously Razer didn't do this, Though I doubt that is a fast process. Either Razer knew the product wouldn't pass or wanted to get to market faster. I suspect the latter was more important to Razer. Remember like Linus says: Corporations are not your friends. Now lets pretend for a moment the Zephyr did actually get a certification, they still are not liable, not even ethically. See the standards certificate does not mean you are safe wearing a respirator. Essentially for a respirator to be considered safe for yourself there are 3 components: Filter rating, Quality rating(ANSI, CSA, ect.), and finally Fitment. Filter rating we already discussed, Quality rating is more focused on the assembly; do internal seals leak or not, how long do one way valves last, how well do the straps work, there will only be minimal accounting for fitment because again faces are too unique. There is basically no such thing as a one size fits all respirator at least nothing comfortable. Which is why high standards industries like mining and healthcare must do individual fitment tests on each and every employee. Healthcare workers who prefer to use mask type respirators because they are disposable are individually rated for specific models. I remember a nurse I knew back at the beginning of the pandemic who was very distressed because the only respirator she cleared fitment on was discontinued. Also of note is that no traditional respirator can achieve fitment when a beard is present, though most can accommodate mustaches. This is why you'll never see commercial airline pilots with beards, but mustaches are common. Though in their case this is for their emergency oxygen mask, but the principals of fitment are exactly the same. Oh and Razer has always had this text on their page: "User to ensure device is worn properly to form airtight seal" and I would not be surprised if it's on the physical product literature as well. Legally about the only leg one has to stand on is Razer's use of the word "safe" but really that's a larger discussion of accountability of using buzzwords in modern marketing in general IMO. Nevertheless I think it is productive discussion to question whether Razer should be using the word Safe in their marketing. However I think that the discussions like those on the WAN show are of bad faith and false expectations. Razer delivered a unique and interesting looking product in a timely enough manner that still exceeds the common standard of cloth coverings and cheap surgical style masks. No doubt we'll find somebody calling me a Razer fanboy or shill for this post, so I'll respond to that. No I don't own a Zephyr, Yes I do own Razer products. I think that Razer products generally deliver quality proportionate to their price tag, especially factoring how commonly available they are. Almost certainly there are better quality products to be found for similar or even better pricing, and I applaud those that do buyers research to obtain those products. Nonetheless it has been my experience that Razer products do provide an acceptable longevity for the price they cost. Also Yes I've heard that this is not true for all their products, especially their laptops, I would probably never buy one. The purpose of this post was an informative commentary on the public misuse of standards to foment a false perception of personal safety, and the way this was displayed on the most recent WAN show by both Linus and Luke. Ultimately you yourself will pay the highest consequences, and nobody cares more about yourself than you do, putting the highest burden there in the end. The other guy pays their lawyers just enough to stay on the far side of liable or responsible, because they only care about your money. I get it, people like to crap on Razer, but that doesn't actually make you a better more informed consumer.

I think the title says it all. A section for giving feedback on LTT merchandise be it sizing, quality, material types, uses.

"There are no active wake timers in the system."

Hey all, I'm looking for troubleshooting a very curious issue. I'm running a desktop PC Windows 10, sometimes I can't put my machine into sleep mode, and worse sometimes this persists so far as I can't get it to stay turned off. Here's what happens: I tell the system to enter sleep mode and it will do so, system appears to be fully dormant. No fans, no lights, no USB signals, no video signal; for about 5 seconds. It then wakes all on it's own with no user input. like a normal wake up process. Worse still often if I then attempt to do a Shut Down from windows it will do the same exact thing only now it's a full boot, again with a few seconds of apparent dormancy. My only solution is a power button forced shutdown. It doesn't always happen, maybe 25% of the time. There seems to be some correlation with which task it do beforehand but I don't know which. I suspect it might somehow be a wake on LAN signal, the UEFI isn't the greatest but I think I have Wake On LAN turned off too. Any advice? Anywhere I can search for the trigger?

Solar PV is an interesting technology. As far as installation goes it scales linearly. Though I will admit that buying in bulk is always cheaper. But this is to say that adding panels gives you a 1:1 increase in output. No other system is like this except wind turbines. Most systems have exponential effect when you change the scale. Or recieve other limitations. The only part of solar that does scale exponentially is the quality of the inverter you can provide. Though you need an epicly huge array before this triggers. Though this is really more of a comment on grid integration. I feel that solar is a great technology to charge batteries and I'm mostly looking at vehicles when I say this. I think it's a terrible technology for mission critical applications. I also like it for 'some electricity is better than none' think rural locations in the developing world. Any amount of labor saving machines to liberate women, or powering Internet access for education. But if a grid exists I prefer concentrated generation, particularly nuclear. That being said I do like the idea of renewable DC micro grids. Small towns or suburbs that share solar but aren't inputting to the main grid. Though this is very bourgeois.

So market prices are a ring and do matter, however every product has a base price, meaning a minimum sustainable price. This includes production costs, shipping cost, sales cost, install cost, and done profit so those people can provide enough of a living to incentivize keeping their company in business. I have much trouble following your writings, but it doesn't seem like your philosophy has accounted for this minimum.

I have no idea what you're saying.

My words were that I was lukewarm at best about the cost effectiveness. What you must understand is that present solar integrations are completely biased and uselessly unrepresentative of the cost model. There are almost always subsidies so you never pay the actual price, selling to the grid won't scale. Right now basically nobody has solar, were you to round off to the nearest whole number 0% of the population had their own solar. That's how few actually have solar. So when power grids do buy solar from residential systems it's strictly a PR move. Similar subsidies are also PR expenditures. Were solar to go mainstream then those subsidies will disappear or be hugely reduced. While power companies simply won't buy it at that scale. The price is too high, the power is electrically dirty which damages the grid, it's too unreliable, and the administration costs would be obcene. Without subsidies and grid purchase the residential solar integrator pays the real price and while in theory they will pay less than buying from the grid. The break even point is at the 15-20 year mark. And you have to pay up front or get a mortgage loan for your solar, which raises the total. The big issue is that a solar system lasts only about 15-20 years before it must be replaced and the output deminshes over the lifespan too. Further extending the payoff period. So basically in a general deployment of solar you don't save any money, the lifespan of the system affects your home sale price. The only positive outcome is that you are living on reduced carbon, though solar production is extremely toxic, as is recycling old panels.

I'll answer the bit about cost effective in another reply. 1. It is common enough though often this is planned with new construction. I really only meantion it to signify I've accounted for the option. And don't recommend it for LMG. 2. Parapet: a wall that extends above a horizontal surface but is not enclosed. Roof deck: the rigid structural component of a roof. I think you're suggesting a horizontal beam that bridges the the entire roof resting on the parapets. While such things exist(see photo) this would not be a good application for this purpose. I'll mostly file them in the 'trust me' category. But one reason is that the parapet for the LMG building isn't all that strong, especially against the added wind sheer. While the parapet in the photo is atop a much stronger concert parapet. 3. Atop the roof works directly against gravity, mounting to a wall puts the stress at an angle. Roof leeks are definitely a concern but I've that can be migrated. 4. You've missassumed the hazard. The risk is falling off the roof. Not roof collapse. As a roofer I play cat and mouse with occupational health and safety on a constant basis.

So a few weeks ago (floatplane calender) a video was posted where @LinusTech mentioned that solar might be a project LTT/LMG could engage in. While I'm generally lukewarm at best on the cost effectiveness of solar. I'll put those opinions to the side now and focus only on the building integration side of adding solar. I'm a commercial flat roof installer with over 10 years experience, I'm also well learned in most external building systems. When adding something like solar to your building there's a bad way, a good way, and a best way. Not surprisingly the price is proportional. Though this is only the install price, down the lifespan it's back to front. There are two ways to mount solar. To the side of a building or onto the roof. Greater latitude means more angle on the panels as well. Likely we can assume that LMG would opt for the roof install. There are a few areas of consideration: Building Integration: LMG studio has a single ply ballasted EPDM rubber roof. This means that the water is basically kept out by fully cured inner tube rubber (EPDM). And the 1-1_1/2" inch stones spread across the roof are ballast to hold the roof in place against wind tear off. Though they also have the effect of blocking UV rays from the membrane, which is always handy. This type of roof is relativity inexpensive but performs extremely well against the forces of nature. Unfortunately it performs poorly against the meddling of humans, more on this later. Any solar array will be build onto a metal skeleton, the point we want to look at today is how that framework installs to the building. The simplest method is to simply place said framework upon the roof and weigh it down. This is the dumbest idea ever, just ask the Canadian Tire store in Kenora Ontario who did exactly this on a roof identical to LMGs roof. They spent a lot of money hiring my classmates to repair many holes after water leaked into the building then more reinstalling the framework properly. The proper way would be to use rubber mats or rubber bricks (C-Port is a popular choice). This method also would use some variety of ballast weight. However while being somewhat less expensive it takes up more space. My personal choice is to fully anchor the framework to the building itself. There are a couple of ways to do this but both would have you hiring a roofing company to "tie in" the structural mounts to the roof. This method would not require a structural engineer assuming your panels aren't too heavy. If done properly this is the cleanist looking install, and you're not relying on ballast to secure your panels. Technically this method can be done DIY as there aren't any expensive special tools needed however your roof is the first line of defence keeping the weather out of your building so if DIY, best not make costly mistakes. Electrical integration: Simply put the power needs to entry the building. This can be done through the exterior walls or through the roof. I recommend going through the roof as it's less external electrical. Again same warning about messing with roof applies. Roofers aren't the cheapest but far less than mistakes. Maintenance: I'll be honest I don't know how well rain cleans solar but one must consider dirt and possibly snow buildup. Regardless at some point you will need to access and service. LMG already has an advantage since their building already had a roof access ladder. Some thought may want to be put into providing a rooftop walkway, this would essentially be rubber mats or patio stones with a protective layer between stone and roof. Don't worry I'm not saying you need a metal gantry way or anything so fancy. Another possible feature would be an external water tap. There are special kind that have their value inside the building so water won't freeze in the pipes. Safety: This is part of the maintenance section. Working at heights is regulated by each province through their workplace safety administration. And an uncontrolled rooftop requires special training of a worker who is on the roof. Yes that remote access video LTT just made is a workplace safety violation though I can't imagine they'll get trouble over it. IMO the easiest solution is to turn your roof into a controlled workspace. This is easily done by having maker lines that show the worker where the safe areas of the roof are. Essentially a series of posts with cables strung between them forming a corridor from the ladder to the solar and creating a perimeter around the solar. They could of course ignore this safety portion, and have a fair chance to get away with it. However an once of prevention, saves a pound of cure.

sometimes yes, usually no. if you're not doing 4k then no. There is an argument for future proofing for VR though. IMO: 1080 for 4k 1070 for 1440p 1060/1050ti for 1080p

Ok I have to ask, is there something wrong with you? no seriously. Parse through the argument you just made twice, yes it was the same argument and I got it the first time BTW. You say: "if there is positive ROI it is effectively free.." So forget about coin mining and apply this statement to literally any aspect of life. Wouldn't you always seek a positive ROI in literally everything you do? I mean that's what you've said, perhaps not what you intend but it is what you've said twice now. Why would you seek anything other then a positive return on investment. 'I just bought this tractor, I'll never see a net gain from this purchase. But I'll sleep easy knowing the John Deere Company made a sale.' I mean nobody would think that way NOBODY!!!!! So I'm afraid discounting perhaps the depths or Marxism, that this ROI argument you've made twice is not at all an argument. Unless you intend to argue any positive ROI equals free, in which case we need to contact the dictionary people and let them know they need to change the definition they are using for the word FREE.

Yeah this was complete nonsense. Basically everything we do in life is getting back more than you put in. Not always in monetary sense of course, but you wouldn't buy a smart phone for say $1000 if it was only worth $500 to you. you wouldn't employ your time is it wasn't worth less than your wage. a $4 loaf of bread is likely worth the value of not starving, priceless really. as for the Zero man hours, there's many examples of this and I've never met a miner who didn't have to invest a huge amount of both time and resources to learn how to mine, build their setup, program their array.....ect ect. But even then, American oil firms extract the oil in the UAE. Do those Arab land owner oil baron who basically cash the checks, is it free money for them? You lot need this idea that miners do nothing and get everything. But they have much much value tied up in their rigs, you don't have to like the model but you can't simply lie about it.
