My personal favorite that I've seen is FLAMINGASS (Facebook Lyft Amazon Microsoft Intel Netflix Google Apple Salesforce Square) (at least one of these is definitely a bit of a stretch)
kibibyte··on Chronicles of a Bubble Tea Addict
How did "boba" become the de facto term for the drink? I remember calling it "pearl milk tea" in middle school, somehow switching over to "bubble tea" in late high school to college, and now calling it "boba". And I don't think I heard of the slang meaning until much later.

Aside from that, as I am a first generation (native-born) Chinese-American, this article discusses my identity scarily well from an angle that I never really thought about. Despite Subtle Asian Traits becoming popular around the time that I was cutting my Facebook usage after I graduated and started work and "boba liberalism" being a term I learned today, I'm not really that many steps removed from this all. Why is it that I subconsciously tried hard to prove myself to classmates that I'm an American, but on the other hand, I tried to be as "Asian" as my Asian-American classmates? This article hit a cultural identity nerve in me and I haven't really formed a coherent set of thoughts on it.

(Maybe this also ties into why I'm such a boba purist in that I reject anything that isn't tapioca balls + whole milk + some sugar but not too much + good tea, though when I'm feeling less tolerant of lactose, oat milk surprisingly tastes almost no different from whole milk in a boba drink.)

Also, the boba metaphor for culture that the author presented also really works well in another way. A person born of parents from Shanghai and a person born of parents from Beijing can have very different cultural backgrounds, but that richness gets lost when they become Chinese-Americans. Similarly to how boba, a Taiwanese drink, has become a de facto symbol of Asian American cultural identity overall. Some might argue this is a "bad thing", but, well, as I mentioned earlier, I'm still coming up with a coherent set of thoughts around this.

kibibyte··on How long does a bottle of wine last after it is opened?
You just have to set realistic expectations. Some internet people have done tests and concluded that it does extend the life of a wine by a couple of days, and some internet people have not found a difference. Based on anecdotes from a friend, it works better on some wines than others. I haven't searched hard to enough to come across anyone claiming that it makes things worse.

For a $12 thing, it's not a huge investment to get one and see for yourself whether it works or not.

kibibyte··on California law bans delivery apps from listing a restaurant without an agreement
Is it also possible that food-contaminated styrofoam is significantly costlier to recycle than styrofoam on its own, or did this specialized process also take care of this problem?

Is that actually true? I've always heard to put styrofoam in trash rather than recycling.

kibibyte··on Robinhood Accounts Looted, No Customer Support
On its own, there's nothing inherently wrong with it, aside from it being a very awkward user experience.

But here's where it can go wrong, using ETrade as a specific example. ETrade appends the 2FA token to your password, but also enforces a password character limit. Yep, that means turning on 2FA reduces your password character limit. From what I hear, it has some surprising behavior if your password is already at the character limit and you turn on 2FA.

(Aside: ETrade has some very sketchy security practices, like apparently letting you use the 2FA token on its own to reset your password (according to a coworker), but that's another discussion.)

For me, it sends me to a secondary login page that asks specifically for the Symantec VIP or hardware token. If they are appending it to the end of my password, it's not evident to me.
kibibyte··on McAfee S-1
Silly compliance checkbox perhaps? I'm vaguely aware that certain PCI standards require organizations to install anti-virus software with specific requirements.
kibibyte··on Smoke has caused temperature forecasts to go crazy
Certainly yes, it's better indoors. However long it'll take will depend on how good your insulation is (a lot of older construction in the Bay Area has really poor insulation; after all, we don't have to deal with harsh winters). That said, when it gets really bad outside (AQI >150) for over a few days, it's almost certainly going to get bad inside if you don't have any filtration.

One thing worth mentioning though is that the smoke you smell is volatile organic compounds, and the smoke you see is (I believe) PM10. You're not going to smell or see PM2.5, which is what these HEPA air purifiers are designed to filter. I'm not confident in this, but my intuition is that these smaller PM2.5 particles will find their way into your home more more quickly than the larger PM10 particles will.

kibibyte··on Smoke has caused temperature forecasts to go crazy
Looking at the current Amazon search results for “air purifier”: first one doesn’t ship to California, second is out of stock, third one is ridiculously expensive ($800!) and been shown to have a questionable effectiveness, fourth one can only cover a small room (and won’t arrive until next week), fifth and sixth ones are out of stock.

Also most people don’t enjoy wearing an N95 mask for a long time. Imagine wearing one for 8 hours while trying to sleep because you haven’t been able to get a filter. You can try to close every window and door and such in your house, but no one’s insulation is perfect and the air will get bad after a few hours.

kibibyte··on Let employees sell their equity
What is a reasonable range for an answer to (A)? I know it's going to depend on what stage the company is at, and I figure 1% is probably going to be the upper bound, but I don't know what the lower bound should be.
kibibyte··on Let employees sell their equity
I suspect it may be the IPO underwriters, the big financial institutions that most companies going public will work with to make their shares available to the public. In short, the company and these institutions negotiate the initial price of the shares beforehand, and on the day of the IPO, those institutions purchase those shares from the company at that price (thus funding the company) and then immediately flip them (hopefully for a profit) to the masses.

kibibyte··on RBS, Ruby’s new type signature language
One thing I never really figured out with Sorbet is how it would work if I wanted to distribute a gem with type checked code. A typed gem would necessarily have to depend on the sorbet gem. Wouldn't this mean library users have no choice but to opt into type checks always being run in this library? (Is this why sorbet-runtime exists?)
kibibyte··on Comet streaking past Earth, providing spectacular show
I've found that the main challenge so far hasn't been the light pollution, but that the comet hugs the horizon so closely at about 45 degrees NE in the early morning hours. In the big city I live in, it means that there's often a surprisingly tall building obstructing exactly that view, even at a few elevated city parks I live close to.
kibibyte··on The Dactyl-ManuForm Keyboard
A slight tangent, but one very nice side benefit with split keyboards is that if you use a Mac and use a Magic Trackpad, you can fit the trackpad between the two keyboard halves and split the mousing load between your two hands. Just switching to this setup (versus a normal mouse off to the right) took a lot of pain off my right wrist.
kibibyte··on Iridescent Tempered Chocolate
Ah yes, those have also made their way onto kitchen countertops (e.g. the NutriChef Oil Press), but I'd agree that they'd be in the "advanced machinery" category.

Most small batch chocolate makers don't bother with pressing their own cocoa butter because of the scale required to make it worth it. There's only so much cocoa butter you can press from beans, and then you need to figure out what to do with the remaining cocoa solids. (As an exception, Goodnow Farms is one that did invest in one for, I think, $50000; they sell the cocoa solids to restaurant chefs.) As a result, most of this is still in the industrial realm, even if the tech itself isn't particularly new (it hasn't changed much beyond what's in the linked video).

kibibyte··on Iridescent Tempered Chocolate
I'm not sure what you consider to be "advanced", but you can get surprisingly really far with just machines that can fit on your kitchen countertop and still produce some pretty high quality flavorful chocolate. In fact, the main equipment that you need to purchase is a tabletop melanger, which is required to refine the chocolate. (Nowadays, you can purchase melangers specced for refining chocolate for 24-72 hours, but perhaps 5-10 years ago, many people were abusing melangers (wet grinders) designed to make dosa batter in 30 minutes.)

For the whole process, pretty much all you need is:

1. an oven to roast cocoa beans (though you probably want a tabletop coffee roaster for reliable results)

2. a rolling pin to break apart roasted beans into nibs and husk (this does get old pretty fast after 5 batches of chocolate, so people recommend moving onto another kitchen countertop device, the Champion Juicer)

3. a hair dryer to separate husk from nibs

4. a melanger, as mentioned above, to refine the nibs (with any desired additives like sugar and milk powder) for 24-72 hours

5. a couple of bowls and a good thermometer for tempering

6. (optional) plastic molds for shaping your chocolate.

kibibyte··on Help Take the Fight to COVID-19 with BOINC and Folding@Home
VMware just announced a Folding@Home virtual appliance. https://octo.vmware.com/vmware-appliance-fah/

I'm fully aware that this is not a container, doesn't run on free/open-source software, etc. etc. but it's an available alternative now.

kibibyte··on Help Take the Fight to COVID-19 with BOINC and Folding@Home
My CPU client occasionally gets new work units, but it's been idle for most of the week.

Currently, it looks like one of the main issues is not having enough server capacity. If anyone has extra resources or expertise to contribute, see https://foldingforum.org/viewtopic.php?p=314382.

kibibyte··on Dow Falls 2997 points worst drop since 1987 crash
> in big drops there's a chance that the 3x ETF may actually implode

Huh, I didn't consider this possibility because I can't imagine the underlying index (this one's related to the S&P 500) going up enough for that to happen. But then again, I suppose those speculating in XIV didn't expect those volatility spikes either.

For me, though, I figure the downside is capped for the relatively small amount of money I put into this 3x inverse ETF: if the fund goes all the way to $0, then I've only lost the original investment. (But also, if it goes to $0, that's probably a good thing for the rest of my portfolio.)

kibibyte··on Nvidia calling gaming PC owners to put their systems to work fighting Covid-19
You should post your problem in the F@H forum. Back when I last did any serious folding stuff 10 years ago, people on the forum (some of whom still seem to be pretty active today) were immensely helpful with these kinds of problems. https://foldingforum.org/
kibibyte··on The human genome is full of viruses
I generally get annoyed at most analogies that compare DNA to code because they oversimplify a lot, but I really do like this particular DNA-code analogy.

My university molecular genetics course taught me that DNA is very complicated. Many of us know of the simplified model where an RNA polymerase, encouraged by some transcription factors, locates and binds to a promoter sequence, unwinds the strands, and constructs an RNA strand. However, DNA has a 3D structure. Histones can wind up DNA tightly enough to hide genes from transcription proteins, or they can unwind and expose DNA to encourage expression. Some transcription factors can bind to sequences several kilobases away from the target gene, cause that part of the DNA to fold onto itself, and ultimately bind to transcription proteins to encourage expression of the target gene.[0]

Extending your comment, it is entirely possible that bits and pieces of old viral code have accidentally led to weird things like this, and that many organisms now depend on this behavior.

[0]: https://en.wikipedia.org/wiki/Transcription_factor#/media/Fi...

(In the course of reading about transcription factors, I came across something pretty neat that's related to all this about 3D structures: https://en.wikipedia.org/wiki/Transcription_factories)

Edit: I should also mention that, if it wasn't obvious, that viral DNA getting inserted into certain places can disrupt these complex interactions by increasing or decreasing the expression of a gene. For the cell/organism, this can be detrimental, benign, or perhaps beneficial.

kibibyte··on The war on food waste is a waste of time
With regards to Asian market produce, I think this is not necessarily always true. It's a mix of second-rate produce and very different (and perhaps very local) supply chains.

You can almost think of Asian produce markets as farmers markets.

kibibyte··on Guessing smart phone PINs by monitoring the accelerometer
A few years ago, ANZ Bank offered such a device that they called FastPay. It connected to their mobile phone POS app and helped randomized the PIN entry on the app. Here's their marketing demonstration on it https://youtu.be/I27-B36SaAg?t=80

I'm not sure if it was so much to defend against this type of attack as it was to ensure that no software could intercept taps on the screen and derive your PIN. I believe that the part of PCI rules that cover PIN entry led to this implementation, since this is a mobile POS app running on a potentially hostile device. Typically, POS vendors build dedicated hardware for PIN entry because it's much easier to lock down a system that they have full control over, and thus comply with PCI rules.

(For what it's worth, PCI now has rules on software-based PIN entry on mobile phones.)

It's still unsolved. The main witness on Guandique's trial was found to be very unreliable, so the case was dismissed.
