Individual anecdotes are also informative but the scientific data is pretty clear, women who are more attractive and men than are taller (and more handsom) do better in business and wealth. We have strong biases towards them. It doesn't mean all attractive and tall people do well, just there is a clear trend across society that they are promoted more.

The other thing that's being missed is even for proper masks there are time limits to their effectiveness. That doesn't matter so much for health care professionals who should be frequently replacing the masks, but it is relevant to members of the public walking around.

Either they're keeping the mask on all day and it stops being useful after an hour, or they're taking it off and putting it on as they go in and out of shops.

> This study was conducted to check the efficacy of face masks in limiting bacterial dispersal when worn
continuously in Operation Theater. A comparison was done to find out difference between fabric and two ply
disposable masks. The first sample was collected prior to wearing the mask, using cough plate method holding
a blood agar plate approximately 10 -12 centimeters away from the mouth. The personnel were asked to
produce “ahh” phonation. Participants were then asked to don the face mask, continue routine work and report
to the study center located inside the theater for further sample collections at designated intervals of 30, 60,
90, 120 and 150 minutes after wearing the fabric mask made of cotton. The study was replicated on immediate
next day using two ply disposable mask keeping all the other conditions and personnel exactly the same.
Bacterial counts before wearing the mask were 5.36±4.38 and 5.7±2.99 on day 1 and day 2 of study. Bacterial
counts were 0.96±1.06 (P<0.001) and 0.7±0.87 (P<0.001) at 30 min; 2.33±1.42 (P<0.001) and 2.36±1.03
(P<0.001) at 60 min; 3.23±1.54 (P=0.007) and 4.16±1.78 (P=0.011) at 90 min; 5.63±4.02 (P=0.67) and
4.9±1.98 (P=0.161) at 120 min and 7.03±4.45 (P=0.019) and 5.6±2.21 (P=0.951) at 150min respectively for
fabric and two ply disposable mask. Counts were near pre-wear level in about two hours irrespective of the
type of mask. There was no significant difference between cotton fabric and two ply disposable masks. Face
masks significantly decreased bacterial dispersal initially but became almost ineffective after two hours of use.

> Er, everybody switched to SiC MOSFETs, so... definitely not.

Definitely not everybody are on SiC parts, let alone MOSFET only designs. Though, the trends is for at least some hybrid SiC parts as they are getting cheaper.

When switching speeds are low enough (as is in EVs,) you don't need that much switching performance. Current Si IGBTs are quite viable in EVs, if you switch high enough voltage.

There is a reason why rail is still preferring high voltage AC for traction. That's because Si IGBTs for that are cheap, and efficient enough.

Thanks for sharing your story. I can relate to some of your experiences, although you definitely had it tougher than me.

She called the owner of the local ISP and essentially traded me for internet access; I would go to their "office" (a repurposed shipping container) to answer tech support emails, and at home we could dial in for free.

This is where "unschooling" truly began. I had Microsoft Encarta that came with the PC, I had a book called Internet For Dummies, and I had virtually unlimited access to information.

This was a breakthrough moment for me also. The local ISP offered shell or SLIP accounts, but SLIP was more expensive so I had a shell account. Mosaic was still buggy back then and it required the Win32s extensions to run on 16-bit Windows so I didn't bother. Gopher and FTP were the centers of my world.

My book was Navigating the Internet by Richard Gibbs.

Do you ever wonder if you would've ended up in the same place if you'd had an easier or more privileged upbringing? I'm convinced that most of my hardships growing up were essential factors in how I ended up. If I came up today with high speed Internet and a comfortable middle class life with a new smartphone every two years and a computer that I don't have to share with four other siblings, I might not have found the things that I'm so passionate about that I'll do anything just to pursue them.

It's pretty small, but a very cool concept nonetheless.
I was watching a project that involved making a bunch of plastic parts. The total volume was in the low thousands. It was enough parts to start thinking about the scale but not enough to make molds worth it. It seemed like the breakeven point for molds was around 20-50k parts depending on the mold. The design that was used for the final product was made super fast custom made reprap printers with rather low accuracy. Due to the unique abilities of 3d printers it ended up being very strong and durable with a honeycomb structure inside.

3d printers are at the point were for some applications it makes sense to use them in production. The exceptions are high volume as well as very low volume that has high strength requirements( and even then for metal printers some stuff can be done post-manufacturing).

Thinking im buying a classic one next time again. Don’t really need the noise cancelling. Have different ones for that
That's funny. Just yesterday I wrote a blog post that mentioned telerobotics [1], as I've become interested in how the global economy has changed since 1990.

The book I was reading that inspired it (which I thoroughly recommend) [2] talked about how telerobotics was going to help break down the last of three constraints on globalisation: moving people.

The other two are: cost of movement of goods (1st modern industrial revolution); and the cost of moving knowledge (the 2nd modern revolution, since 1990).

One of the things argued is that cleaners and dog walkers (for example) can't be moved, so a paradox of high skills economies is that certain low-skill jobs become more valuable.

$20K is getting frighteningly close to start making it more economical to have someone operate such a cleaning machine remotely from a low cost area than hiring a local cleaner. Skilled operators could even (with the help of AI?) operate dozens of these at once. Or they could do the 'easy' stuff, and get a 'proper' local cleaner in once in a while to do the tricky bits or a deep clean.

Interesting times.

When I was trying to replace or return my 1 year and 2 week old Macbook Pro to Apple due to what turned out to be a faulty logic board, Apple said it was too late as their 1 year warranty had passed. But here in Australia we cannot just sign our consumer rights away. I explained this very clearly, that I was not seeking a return based on Apple's warranty but rather seeking a return based on the consumer rights that govern my country and any businesses that wish to do business here.

Many large companies have tried to skirt around these consumer rights, like Steam and E.A who both rejected the notion that they even do business in Australia, all to prevent issuing refunds. It's absurd. Telling a consumer they have no right to a refund when they do is even against the law here, yet Apple do it all the time.

Eventually I got to a senior representitve and they openly stated to me while denying my claim "I don't know why you expect me to know the laws in Australia". They bloody well should, though. Australia's consumer rights watchdog even forced Apple to display a notice on their website to prevent people being misled by Apple.

The historical nature of or convention on the web has been first come first served on names. Most well designed systems will never change a username due to inactivity or for any reason other than the owner requesting it (even that’s not allowed on most systems). Usernames that aren’t actively used, after a known period of inactivity, may be deleted along with content associated with that username.

Look at email addresses: platforms like Gmail and Yahoo will delete your account for inactivity with adequate advance warning, but they will not release your email address for someone else to claim in the future (on the other hand, paid platforms like Fastmail and Posteo will allow your deleted addresses on their domains to be grabbed by anyone).

With GitLab’s policy of renaming inactive accounts without any warning or notice, any links that someone has shared could later point to a different person. A “404 Not Found” error or an “email address does not exist” error is far better, IMO, than redirecting someone to a totally different person.

If an inactive username is to be released back for use by someone else, there should be a significant duration from the time the username is disabled to the time when it’s available for someone else.
IIRC they have a minimum payment. You need to put $5 in your account. Not sure what they do if you pay by subscription and only use a few hours, but when I was using DO, you needed to fund your account with $5 even if you were using the $100 free credit from GitHub education.
One of my laptop speakers broke. They replaced the entire top of the laptop. Didn't ask for an invoice because they saw the laptop was covered by warranty.

>A lot of software these days is run by JIT compiling VMs, anything Java, anything JavaScript, and that trend is likely to accelerate in future with new tech like Graal that can JITC even stuff like LLVM bitcode or Python.

That's theory. Practice is that JIT-compiled language generally performs even worst than compiled language with an outdated instructions set.

And there is reasons to that, compiler passes are expensive, including vectorization, and you specially do not want anything expensive running in your critical JIT passes.

Some language like Julia still do it but to the price of a very long compiling and starting time.

> Nevertheless, shouldn’t publishers be free to choose how they fund their creations?

Of course. The problem is when they demand that goverments take away their ciziten's natural rights to copy and share information in order to support their chosen business model. If publishers want society to make their business model possible by being given special "rights" and having public institudions enforce those "rights" then it is very much up to all of society to choose if that is acceptable.

Remember copyright is an entirely artificial construct meant to benefit society by encouraging creators to produce content. It is my and many others opinion that the current state of copyright is a very one sided affair that benefits mainly big corporations while having numerous negative effects on society.

> If we take away the option of artificial scarcity then an entire highly trained professional class will be out of work.

Unlikely. There will always be a demand for entertainment and people interested in filling that demand will find a way to make it worthwile.

But even if the entire entertainment industry would instantly disappear then that would still not be an argument to uphold unjust laws. Professions becoming obsolete with progress is entirely natural. People can adapt.

There are many more option not just spree or saleor. Having not just studied but by building add-ons for shopify working with Shopify API including the new graphQL now I am sure it’s designed for mom-pop store trying to fit itself by custom coding into medium and large size. A medium or large size customer is better served with a custom solution built with open source base which provides all the necessary API and data models to start quickly including UI design see the storefrontUI and vue-storefront+magento.

Shopify and bigcommerce are good for small or mom-pop kind of stores which wants to spend $30-$1000/month based on sales, here shopify can take some trouble out of woocommerce and opencart kind of platform. If it’s more than that open source is still better with custom additions.

It does seem like the poverty line is arbitrary, and it does seem low. Is racism the explanation for every small and large thing?

Where does the article mention the constant money printing which is continuously devaluing currencies all around the world? Does a poverty line even make sense in a world where the currency depreciates quickly? How about measuring the poverty line in terms of currencies which do not depreciate in this way, such as precious metals? Why not mention that all governments all over the world are incentivized to overpromise and underdeliver because they own the money printing press? If a person who is supposed to have a background in economics, such as the author of this post, doesn't even mention this, then what hope is there for the lay person?

> People filtered in the past by what they cared about and who they spoke to. Now much of that filtering and indeed much of your friends are algorithmic suggestions.

But the suggestions are based on what you like (or what the algorithm "thinks" you like), and I don't believe that we're converting communists into libertarians because Twitter says "other people you might like: ".

The process is very similar but has gotten gotten much more efficient, because you're not limited to the people in your immediate vicinity. You don't need to move to a big city to find other people who think like you. The world has become a village, and you can now connect with your ideological doppelgangers around the world from the comfort of your home.
I suspect what made companies exclude easter eggs was a sense that they were too big and "serious" for this sort of whimsical activity. And specifically for Microsoft, a sense that they were now targeting the Enterprise marketTM and were above all this consumer-grade behaviour. Interestingly Google still has easter egg behaviour for several queries, e.g. askew[1], which fits well with their corporate brand.

To be clear, an easter egg is only supposed to be a (pleasant) surprise to the consumer -- not a secret kept from the rest of the team, especially QA. You can and should absolutely test your easter eggs.

Yes, Excel's increasingly elaborate easter eggs[2] would probably find it hard to get past security review these days. But to say that easter eggs are bad because security doesn't make sense. Especially when companies include undocumented features in software all the time -- e.g., typing '=rand()' into newer versions of MS Word produces some random text, probably a lorem ipsum generator-like feature.
