> while most others site charge $7-10 shipping or have a minimum of $75-100 for free shipping.

Target and Walmart both have free shipping for orders over 25/35 depending on which items.

Our local Target also offers drive up service where they'll load items into your trunk for you, and you can combine orders so you pick up $30 worth of items same day and get a $5 item (not in store) shipped free since the total is $35.

2 day shipping and 5% off with Red Card makes it a pretty compelling competitor to Amazon. Especially with all the fake/potentially unsafe items on Amazon, I prefer to get food related items from Target if possible.
Fully agree. I believe this is also one reason why it's so difficult for successful managers to get honest feedback. Over time, they become more confident, which makes their (sometimes faulty) statements much more convincing.
Self esteem is attacking the is-vs-ought problem. Sure, in the cold, social Darwin paradigm, those without ability have no worth - but this is not how things SHOULD be.

I think it’s important for people to know that they have value, regardless of their abilities. This doesn’t mean that people should not be encouraged to succeed. I think self esteem and achievement can go hand in hand. For me personally, I think believing that I was special helped motivate me to achieve more! After all, If you’re not special, what chance do you have competing against the other 7billion people in the world?

Anecdotally, I was raised by two very people-self esteem parents, and have become fairly successful compared to my peer group. I also remember the first time I heard someone say that self esteem was bad. It came from the evangelical, objectivist parents of a kid I knew in early high school. That kid ended up failing college and getting addicted to opioids.
I doubt the invisible hand would help. Government can by enforcing more competition.
> Do you remember those finicky cables with the screws?

I remember cables with screws (which didn't actually need to be screwed, really.) They were quite easy to use; not any harder than configuring WiFi is, and much more reliable. Less convenient as far as choosing locations, though.

> And installing drivers which then crashed or hung your computer?

I've been using PCs since before OS-level printer drivers were a thing and through the whole era where they were, and I've never had problems with printer drivers on PC (well, outside of mismanagement by IT on work computers.) I've had problems with drivers on Linux, and with printer support apps (effectively drivers) on Android on personal devices, though.
I ordered some Christmas presents to be delivered to my parents' house yesterday and was amused to see that I could choose to have them delivered on my Amazon Day.

Seems like Amazon Day should be tied to an address, not an account, but I guess it's an edge-case not worth addressing.
Yeah, I'm really surprised by how dependent I've become on Amazon, a company I don't even really trust. The convenience can't be understated, especially as it's not really apparent until you start buying a lot from a site like Amazon.

I didn't realize I hate shopping in a physical store until I started using Amazon. You spend 99% of your time either wandering through aisles trying to find what you want (which they usually don't have) or waiting in the checkout line.

Neither of those things apply to online shopping. The biggest hassle when shopping online is having to login and navigate to dozens, if not hundreds of different websites, re-entering your personal info each time. But a site like Amazon is the Internet equivalent of a department store that has everything, so you only have to login once.

Even if Amazon's prices are the same as physical stores, or even a little more, the time I save not having to drive in traffic and waste walking around a store or standing in lines still makes it worthwhile.

> Do you regularly record interactions with your coworkers, on the chance they may say something incriminating?

That's a silly response and you know it. If there was systematic racism, as the article seems to be implying, then yes, I would record it. I would record it even if it wasn't directed at me but someone else. If more than 50% of the black employees are leaving due to "racism" then of course I would record it. Wouldn't you? If a manager was being racist towards your co-worker, wouldn't you record it? Or are you a racist?

> This sounds awfully similar to the argument made against women: qualified women just don't apply!

No. I'm saying there is not a lot of black students getting CS degrees/etc. Hence the lack of qualified employees. It's a supply problem, not a demand problem.

> You seem to accept Coinbase/Brian Armstrong's words without question.

No. I specifically said I didn't in the comment you replied to. I said I am open to the idea of racism but I find it very unlikely.

> Why do you feel that the Black employees' words must be critiqued to hell and back?

The difference between you and me is that I just want the truth and you want to push an agenda. I think everyone's words should be critiqued "to hell and back". Including the ceo, black employees and most definitely the political activists at the nytimes. How else are you going to get to the truth?

Interesting re interview experience

I interviewed as a new grad SWE and the process was totally straightforward, and way lower friction (albeit much less human interaction, which made it feel even more impersonal) than almost everywhere else I applied: initial online screen, online programming task, and then a video call with an engineer where you explained your answer to the programming task.
No matter who sits in the white house after this, it's clear that we need a complete overhaul of how we do voting. There's zero standardization or accountability across states or even municipalities.

Apple uses the ARM ISA, which everybody can license, with their own implementation. What should they be forced to open? Something about the GPU? I doubt anything about Apple is really bleeding edge. It's the vertical hardware-software integration which makes wonders.

If AMD (which already owns a good GPU architecture) chose to make an OS, it could get the same performance.

One of the last things my mother told me before dying in her fifties was “but there’s still so much I wanted to do”. I drew a “life calendar”, crossed out all the years I had already spent, marked her age when she died and more statistically relevant life expectancies and hung it over my desk. I quit my job and started something new not long after.
Most of these jobs are long term indeed going to be automated away. Order picking in a warehouse is still difficult enough that it involves some people but it's not hard to see how that could be reduced over time. Driving delivery vans is also an obvious candidate for getting automated away. However, short term this is just Amazon responding to increased demand because of Corona.

Mass unemployment would get accompanied by mass loss of disposable income, so that would actually be bad for Amazon. Automating the supply kind of automates away some of the demand.

The notion of bullshit jobs is basically about people doing busy work without actually doing or producing anything of real value. The industrial revolution produced a lot of that already. There's going to be more of it. Easy to predict, because there already is a lot of it.

IMHO the lockdown kind of revealed just how pointless some of our jobs really are. Masses of people suddenly worked from home and it did not really disrupt a lot of the supply chains or economy. Instead of being useless in some cubicle, people now got to be useless at home. Technically that should have been a huge productivity hit; except a lot of these people were never really that productive to begin with. The most important thing these people do in our economy is spending.
Same question. They decided to INCENTIVIZE overdoses? (And "opioid use disorders" too, they were paying rebates for those too).

I don't understand either the ethical OR business sense of this. Very confused.

I haven't been paying too too much attention to this stuff, and I never before felt like saying anyone should face prison over any of this -- but incentivizing overdoses, are you serious? I feel like anyone involved in that decision is a horrible human being, at the least.
But asymmetric crypto does that under hood (hybrid encryption).

In fact, if you encrypt the same file twice with rsa you get different cipher text.

Hurricane country here. Yes, having a couple of weeks worth of food and water in the house during the season is the responsible thing to do. Whether it's modern freeze-dried meals, canned food, or just cycling through your common grocery purchases.

A few years ago I bought a supply of mylar bags and a heat-sealer. I can put various dry items in them, dropping an oxygen absorber or two in there (more for products that have low packing density), and they're good for a few years. Don't forget to write the contents + date on the outside with a Sharpie before filling!

Mom went through rationing in the UK during the war (they heated their house in part by the coal that she picked up along the railroad lines), and she always had a well-stocked pantry. Home canning was too much work for her though, so she just had a lot of store-bought shelf-stable food.
I'm deep into the dataframe/SQL way of doing things but I also use Excel a lot.

In my opinion, spreadsheets provide a different paradigm that dataframes do not supplant. In theory anything in Excel can be done in a programming language (that's obvious). In practice, certain tasks are simply easier do in Excel.

Excel is essentially a functional reactive calculator on a visual grid. It lets people quickly create models to test ad-hoc ideas. Because it works at a cell-level, ad-hoc calculations are much simpler. Because it is reactive, you can test different scenarios without recompiling or re-running.

Sure, it has its limitations -- which is why multidimensional modeling tools like Quantrix exist. Also it's true that many people use Excel far beyond its intended purposes (I've come across some really complex Excel sheets with VBA that really should be in a SQL database). And yes, the dataframe paradigm is powerful for structured/systematic and reproducible/replayable transformations of data, e.g. column/row operations, aggregations, filtering.

However, the very structure that makes dataframes so powerful and consistent also constrains it.

In a spreadsheet, you can break a formula at specific cells (for exceptions etc). You can do that programmatically in a dataframe too, but it's a less natural operation which requires ad-hoc coding, whereas in a spreadsheet, you just head over to the cell and change the formula. Or take operations that are easily done via copy-and-pasting, say, like lagging a column by 2 but only between rows 23-65 and skipping certain rows because they're say, weekends/holidays. In Excel, you can carry this out by just manipulating the data directly i.e. physically moving cells around. In a dataframe, you have to extract the required rows, apply the lag operator, and then reinsert the lagged data (and reset indices, or do vertical concatenate) etc. I manage my personal cash flow and do scenario analyses of different kinds (financial, probabilistic, etc.) in Google sheets (and not a database or dataframe) precisely because I can introduce exceptions in the table and perform ad-hoc tasks like test scenarios in real-time easily. If I want to check an idea out, say the calculation of airflow in an aircraft cabin, a spreadsheet (and not a dataframe) is what I'd reach for first.

Navigationally, a spreadsheet also lets you "touch" data and get a feel for it in a way that dataframes don't (in a programming language, you're typically always working with a subset view of a dataframe, e.g. SELECT TOP 1000 * FROM x, or df.head(3) -- these paradigms are the default because of the inherent assumption that all operations have to scale to the largest of datasets). In exploratory data analysis, it's super important to be able to see and feel the data because that's how you discover inconsistencies, sentinel values, exceptions, etc. Spreadsheets give you a low-friction interface (like filter/sort and freeze rows) and a set of powerful functional tools out of the box that generally beats any CSV viewer.
My understanding was that self esteem is actually just the opposite of what it is usually purported - it is how you view how the rest of society views you and your role in it. If that is true, just telling someone "you're special" isn't enough - you actually have to be special and be recognized and respected for it. It's about as useful as telling a person "you're tall" regardless of their height.
Apple Silicon M1: A Developer's Perspective
> We strongly suspect that by the time enthusiasts could reverse-engineer the M1 SoC sufficiently for first-class Linux support, other vendors will have seen the value in bringing high performance ARM systems to the laptop market—and it will be considerably easier to work with the more open designs many will use.

That’s true, but will they have the volume of Apple’s laptops? There’s a pretty decent demand for those. Nobody cares if no-name ARM chip user can run Linux.

> The surgical mask with a beard is kind of like walking around with my hand held a half inch away from my face.

Yeah, but that'd still be better than nothing, too. (As would be a face-shield worn without a mask.) In both cases, the main goal of getting regular people to wear masks isn't to contain exhaled droplets, but to lower the forward velocity of exhaled droplets, so they don't slam right into other people's mucous membranes, but rather have time to get caught in HVAC systems or dispersed into outdoor air.

The faster the droplets are moving when they exit your mouth/nose (e.g. a sneeze or a cough), the less they're going to be able to "turn" to get out the sides of your mask. Masks are very good at stopping sneezes/coughs from contaminating the air, even when badly fit.

That, and masks/face-shields/your own hand/etc. also protect you when someone sneezes or coughs directly "at" your face. Like the sneeze-guard at a buffet. It's not complete protection — the particles, once airborne, can drift "around" the barrier and come in — but it does appreciably lower contamination compared to having nothing there (presuming that people will be sneezing/coughing/breathing directly "at" your face/the buffet. Not a concern for most people; but this is why people in hospitality are wearing the face-shields.)

> All the air is going in and out that half inch.

Out, almost certainly (except for forceful expulsions, as above), but if you're breathing through your nose — and the mask is shaped to surround your nose — then even if it's a half-inch from your nose, at least some of your inhaled air will be coming in through the mask. Even if it feels like all of it's coming in through the gap in the mask. So there will be some fractional protection from that.

Also, I believe high-grade masks are somewhat adsorbant — airborne droplets just like sticking to them if they rub up against them, rather than staying airborne. So a good mask can "passively" scrub the air you're breathing in, even if that air is coming in "around" the mask instead of "through" it! (This is only a small effect, though, and shouldn't be relied on. I'm trying to list the reasons mask-wearing is better than nothing, not trying to justify intentionally wearing your mask less-well-fitted than you could.)

Not the OP here but there's two things to that. As a European coming to America, you generally find the sweets here to be waaay to sweet. You get used to it though.

I also did Keto for a while though and after you've been on that and then you just eat something made from flower again not even with sugar in it it tastes sweet. That was eye openingly weird. Of course that goes away quickly if you start eating it regularly again even if in low quantities.

They don't have to be rigid by the way, though it sounds like that was desireable in your case. I think in general non-rigid is surely more conducive to a good fit.

I have an FFP3 (~N99) one from some DIY pre-pandemic (so cheap, good luck even finding it now! I do wonder what tradesmen who need them for workplace safety, but their work isn't medical, are doing at the moment) - it isn't rigid and fits well.

It is used and 'not reusable', but I'm hanging on to it. If I 'have to' travel or something at some point I figure used FFP3 beats piece of loose-fitting cloth.

> Whether the universe (or our observations of the universe) have finite complexity is very much an unresolved philosophical question.

Every time there was a significant advance in physics, it tended to go towards simplification and unification. Geocentrism required epicycles. Then Keppler came up with his ellipses. Then Newton unified celestial and terrestrial laws. Maxwell & Einstein allowed us to view time as less special dimension than we thought it was…

I won't presume about the initial state of the universe, to the extent such a notion is even meaningful. But the fact that it is governed by mathematics, and relatively simple maths at that, sounds likelier and likelier every quarter-century.

And I'm not even talking about everyday life, where we can observe in practice that the simplest theories about who ate the last cookie (little Mike, who lives in the house) are more often true than the more outlandish ones (magical imps, which we never witnessed).

Quote from article: “The larger problem has the potential to affect every writer. Disney’s argument is that they have purchased the rights but not the obligations of the contract. In other words, they believe they have the right to publish work, but are not obligated to pay the writer no matter what the contract says. If we let this stand, it could set precedent to fundamentally alter the way copyright and contracts operate in the United States. All a publisher would have to do to break a contract would be to sell it to a sibling company,” Kowal wrote.
