Yes, it's also important to note that they typically use surgery masks, not homemade masks or N95. A surgery mask fits very differently and having worn one for hours, I can attest that they are much more comfortable and at least for me don't present the glass fogging issue. They also are not sufficiently protective against coronavirus.

I encourage you to remember that this is a place of meaningful discussion, not brow beating or one-upping.
I had this problem too. Try pulling the bridge of your glasses down a little bit over the top of the mask, that usually helps. Or create a seal at the top as other commenters suggested. Also be mindful if you are breathing out through your nose or mouth, it makes a difference depending on how your mask fits.
Because publicly funded universities hold different ethnicities to different standards which favor particular underrepresented groups simply due to their group identity rather than to a consistent, objective standards.

My spouse’s small business is seeing delays in deliveries the last few weeks it didn’t even see at the height of the pandemic.

And she had something get lost a week ago, something that hadn’t happened in over a year (small sample size though).

We do know that the local USPS has cut back on the hours their employees are working, which is strange considering USPS is busier than ever.
I would not read these rules as anything like suggesting to write O(n^2) code. I think at best I'd read them as favoring O(n) instead of (1) for small n, but I really think that "fancy" algorithms in this case doesn't mean obvious optimizations like this.

If you can't guarantee n is small, I think it is entirely sensible to use a dictionary/hash table instead of looping over an array or list. As long as n is small the overhead is probably irrelevant, and it'll prevent surprises if n gets large as you said. And if the difference actually matters, you get back to rule 1 and 2 and measure first anyway.
FWIW I find this is especially important for compilers and interpreters.

It's not an exaggeration to say that such programs are basically big data structures, full of compromises to accomodate the algorithms you need to run on them.

For example LLVM IR is just a big data structure. Lattner has been saying for awhile that a major design mistake in Clang is not to have its own IR (in the talks on the new MLIR project).

SSA is data structure with some invariants that make a bunch of algorithms easier to write (and I think it improves their computational complexity over naive algorithms in several cases)

In Oil I used a DSL to describe an elaborate data structure that describes all of shell:

I added some nice properties that algebraic data types in some language don't have, e.g. variants are "first class" unlike in Rust.

Have you considered that "societal rules" may have been the predominant reason she tried and failed to find suitable employment?
Ditto! I also try to never tell the kids "don't ask that question." Though very often I do need to answer with "I don't know, but let's find out if anyone does," then research it later. And occasionally, as recently happened when the question was about the Vietnam war: "that is a very long and complicated story, give me some time to figure out a way to explain a little bit of it."

tl;dr Consumers have higher expectations for the quality of mobile hardware and software (driven by iOS and nowadays Android) than Windows can currently provide.

The reliability issues are bordering on a dealbreaker for me at this point. I've had lots of Microsoft hardware; maybe I'm just unlikely, but the only thing that didn't need factory service was an Xbox One. I'm not a Microsoft hater by any stretch, but having to get a Zune 80, Surface 3, Surface RT, and Xbox 360 factory serviced really soured me. I've had several Android and Apple devices at this point and none have needed factory service.

Windows 10 still isn't tuned well for mobile, and the few parts that are just aren't generally reliable. I'm actively working on a UWP app right now and the problems are endless - issues with resizing windows, crashing when themes change (built in apps like Maps have the same issues so its not my code), broken vector icon rendering, etc. The whole thing is based on COM, which tends to lead to leaky abstractions when exposed through higher-level APIs. It is hard enough to make high-quality software on Windows that developers often fail and it leads to weird quirks. Even with traditional desktop apps, getting things like maximize behavior right with customized windows is actually very hard (see Slack, Teams or VS Code on a high/mixed DPI setup).

Here's a small taste of what a modern Windows developer gets to deal with, to accomplish the simple task of displaying a vector icon: https://github.com/microsoft/microsoft-ui-xaml/issues/1494
It seems to be a for-profit commercial company that is fully owned by the non-profit. IANAL, so I don't know the complexities involved with the setup.

It's more complicated than trying to say that the "Mozilla that people think of" is not a non-profit. The Mozilla that I think of seems to be a combination of both.
I’m happy for these students, and the housing stipend they managed to get will help them, but I don’t think it’s a net positive overall. It just adds more demand to the local housing market, so a different set of people on the margins end up homeless. The only way to improve the situation is to build more housing.
Actually, yes. Before the pandemic, it was reasonable for construction workers in the same room to use valved masks. Now they are only appropriate for people working in isolation, which is a less common scenario.
It's just about the perception of injustice. A privileged person facing minor injustices could completely have this mindset. In fact I've met many many people like this.

Privileged people facing no injustice howl the loudest that they are the most oppressed. In fact, facing no justice either, getting away with every crime under the sun.
Agreed. ML and AI are (currently) useful in situations where there is a lot of data, of different types, usually from disparate sources, often sparse, with no known pattern or causal relationship. Shazam and sonar analysis don't really fall into any of those areas.
That quite a leap. Even ignoring other potentially beneficial jobs, do you really think that modern supply chains ("support roles of transportation” of food) can function without the internet?

Using array based data structures also get you more cache hits. For smaller data sets, this may well be faster than a fancy algorithm.
It depends. If you don't need to worry about performance, then it will work. But in some performance-dependent situations, the brute force algorithm will win over the hash table, and the only way to know is measuring which one is better.
If it's fairly easy, then I think it still fits the spirit of the rules. KISS and all.

On the other hand, the idea that one might be setting traps is slightly weird... if you _know_ 90% that n will be large then pick an algorithm that's efficient (and since it's easy to implement, it's a win-win). If n is always going to be small, then does the choice really matter?

It's entirely possible that those options weren't readily available in the local store he's using. I'm not familiar with Singapore in particular but a lot of Asian countries don't have the huge electronics box stores that are common in the US and Europe. I've seen quite a few videos where the best electronic source the person had was what would be a small sized store in a US mall (20 feet wide, one isle with a counter running down one side for example). Online shopping does exist but shipping times and cost can also be pretty large.

Do dishwasher manufacturers publish any sort of guidance for detergent companies for what kinds of detergent are acceptable or problematic for the dishwashers?

Do not wait for perfection. Just come up with a portfolio. Use Github for that!
Yes. If you don't measure, you will never know when the time complexity moves in your favor due to the constant, and other factors. For example, quicksort moves to a O(n^2) algorithm (insertion sort) for the last few iterations of a branch of work(typically n=1000) because this reduces the total sort time.
Most of us have year long leases that we are chained to. If I didn't, I'd be long gone!
It's pretty clear that the opinionists didn't actually read the studies they linked to, since at least one of the studies they cited to claim that single-payer would increase costs actually said single-payer would do the opposite, to the tune of a more than 8% reduction of 2017 amounts, which was before a number of health insurers jacked up their premiums just because they could. https://www.peri.umass.edu/media/k2/attachments/PollinZetZal...

Having read the book and then watched the movie, it’s amazing how much technical detail you don’t even get to approach in the film. This is just the nature of the medium, but the book is very focused on the captain’s inner thoughts and technical descriptions, awareness of limitations, and homages to the mental math involved. Highly recommend the book if you at all appreciated the movie.

I had to do a double take before I realized you were talking about me as well. We live in an information curation economy indeed.

I wouldn't say that's inherently BS, though.
Same thing for a lot of the security clearance forms. "Check here if you have ever tried to overthrow the US government", etc.

Mostly an IQ/reading comprehension thing -- like, an actual spy who isn't a moron is going to leave it blank -- but I've heard a defense of it that's something to the effect of "well, you never asked, so I never disclosed [X]."
That's actually useful information. There are 750FTE at Mozilla. How many of those do you think would it take to do the best job possible on the browser. That would give one way of calculating a budget.
I would recommend webrtc too, its going to be a future for video stuff for a while in browsers and so on.
You are factually correct, of course - of all their random, scattered efforts, the "cost" of finding another VPN provided and switching to it is not large.

I still disagree greatly with your conclusions.

What, exactly, is the massive risk you're
taking when you use a VPN that could go away at some point?

I didn't say it was "massive." I

In reality, the cost to me would be "only" a few hours of research to find a suitable alternative if/when Mozilla folds their VPN service.

Still, like most people, I rely on a lot of software and a lot of services in my life. I work many hours per week. I don't like to spend my limited free time fixing crap and making lateral jumps to alternative things and services if I can help it, unless there's some sizable advantage. If I had to spend an hour or three on everything in my life every six months, it would add up to a lot and I choose to spend the finite hours of my life differently.

So much for trusting Mozilla and caring about privacy and security.

This doesn't follow. Mozilla has a history of introducing and subsequently shuttering many services, so therefore I don't care about "privacy and security?"

For whatever it's worth: I care deeply about Mozilla (and privacy and security) and I do support them financially via donations.
no, that's exactly the misunderstanding that leads to such security theater. distance does nearly all the work. a mask adds marginal benefit when distancing.

when not distancing, like on a cramped airplane, a mask is better than nothing and is doing the work. in that scenario, any mask is better than no mask.

there is no multiplying going on.
I want to medium-to-heavy push back on this.

Techdirt didn't build a single point of failure into their revenue stream, otherwise the title of this article would be, "Why is Techdirt closing down?". Their support page[0] lists 8 different revenue sources other than Google Ads.

And this is precisely the type of diversity that you want. Signing up for 5 different ad networks isn't really good diversity, because:

A) your different revenue streams are cannibalizing each other (there's a limit to how many different ad networks you can shove on the same page), so you can't grow your revenue as you diversify,

but more importantly,

B) many of the factors that affect one ad network (ad blocking, political pressures and privacy laws, fundamental inability to moderate well) will affect all of them.

It's not good to have 5 different revenue streams that can all simultaneously be destroyed by the same event. In that scenario you've increased complexity, but you haven't gotten a significant gain in reliability. On the other hand, pulling in money from advertising, Patreon, merchandise, product commissions, and even Kickstarter campaigns means that no single event will ruin your site.

I think it's important for people looking to diversify income streams to think about what each new income stream offers, rather than just duplicating an existing stream X times. I don't see any advantage in having 5 different frameworks for serving ads on a single site. I see a lot of advantages from setting up a Patreon on the side and selling podcast ads outside of your site.

In theory this should work. I’ve been doing photogrammetry with spherical video and existing software packages often want to “dewarp” the image on to a plane, which works fine for narrow field of view but fails on spherical video. It would be interesting to see if atlas supports spherical input. Also 360 cameras have pretty low visual acuity. My 5.6k GoPro Fusion has to divide those pixels across the whole field of view, so images are less detailed. Still I think 360 video can be useful in photogrammetry with the right algorithms.
Is this an EC2 thing? I've definitely added a new tag to a two year old DynamoDB table and started getting data.
Yes google should have as many people working for it as the advertising industry that it savaged. It should at least have customer service. You know a phone number you call to talk to someone.

These apologies to mega corporate is very sad. I am disappointed in you.
I think the way scale comes in to play for the first two points comes down to who is being moderated / doing the moderation. At scale, the users being moderated are more capable of becoming a politically or economically effective coalition. And at scale, the consistency of judgement becomes harder to maintain. Now you have mistakes not just because judgement was incorrectly applied, but also because the judgement itself was incorrectly implemented.

I would imagine that any multi-hundred-million project has had unproductive branches, pivots and starts. Star Citizens has been been more public, so it's harder to compare, but I don't think many of the others on the list had a straight path to what was released.

> transforming what had previously been an area east of downtown Toronto characterized by desolate parking lots and the graffiti-strewn foundations of demolished buildings

That statement wasn't totally accurate. Waterfront Toronto already had a parklands plan drawn up to beautify the area, add usable space, and provide flooding relief waterways.

The rest of the area actually has a large number of businesses operating—many in the music and film industries. It's not a total wasteland. It's just cut off—one of the reasons the film industry has access to large lands down there.

I worked there for about 5 years so I'm not sure which foundations of demolished buildings they're talking about except for maybe The Hearn (https://en.wikipedia.org/wiki/Hearn_Generating_Station) which has been preserved as derelict so far for film and other shoots. Similarly with the "desolate parking lots". They were filled with trailers for shoots or Cirque du Soleil more often than not.

Just adding some context.
Well on a camera with dual fish eye lenses for 360 vision there’s some blurring at the edge where the images are merged together. But actually each camera separately just has normal fish eye effects, and if both images are used without blending them together you’d have minimal artifacts. Biggest issue is low visual acuity imo.
Genuinely curious - do you think such a mechanism like yours is really relevant to the rest of the population?

> Am I wrong to avoid writing O(n^2) code if at all possible when it is fairly easy to use hash tables for a better time complexity

Are you sure that std::unordered_map is faster than std::vector? Did you measure?

Every time you access an element in std::vector, you also access nearby ones (thanks to L1 cache, as well as CPU-prefetching of in-line data).

In contrast, your std::unordered_map or hash-table has almost no benefits to L1 cache. (It should be noted that linear-probing, despite being a O(N^2) version of hash-tables worst-case, is actually one of the better performers due to L1 cache + prefetching)
It is ML depending on what we're calling ML. Is gradient descent/MLE ML? If yes, then the Dallas (the US sub) in Red October was using ML.

I've been wearing a 3M 7503 that I modded to get rid of the vent (remove all three check valve flaps, cover and seal output port with tape). The modification can't be seen from the outside.

I've been visiting a hospital, and have to explain and sometimes insist that it does not have a vent. The worst is the security guard type people, enforcing what they think are the rules without really understanding them. So far I've been lucky and have been able to ignore/put off the security guard and talk to the friendlier person doing the actual gatekeeping. Human judgment is key to these policies and I can only hope that they're implemented with low-level discretion. It would be terrible if well meaning policies ended up pushing people back towards wearing ersatz cloths.
> specifically intended to put Uber and similar companies in a state of noncompliance with it.

It would be capricious if it were more targeted, written without ample public discussion, or if the affected firms had no ability to continue operations. As I understand it, none of that is true of AB5. For example, the affected companies are free to use contingent workforces in a manner similar to the other many thousands of companies that were not affected.

I'm far from an expert on the law, but wouldn't a fair read also be that those companies were operating in noncompliance with community norms (as expressed by voter preferences), and so lawmakers plugged a regulatory hole?

In that way, could it be seen as similar to a body writing a new law (say) prohibiting people from carrying long rifles into grocery stores? Would that also be a law written capriciously?
