In the UK, according to various sources including the BBC[0], there is plenty of flour, but one of the main problems is that most of the production lines are geared up to producing large e.g. 25kg sacks, given 96% of sales are to bulk buyers for trades like bakeries, with only 4% of flour sold direct to consumers in retail outlets in small 1kg or 1.5kg bags. I'd imagine it might not be dissimilar in many other countries too. So in the UK you should no problem buying a 25kg sack of flour from a wholesaler. There are actually lots of companies who specialise in providing food in wholesale quantities to places like schools and restaurants, most of whoch are in difficulty given their market has disappeared, although some are now temporarily selling to the general public to try to stay afloat[1]. I feel like I've learned an unexpectedly large amount about supply chains in recent weeks.

Hey, I am German. Assembly line worker generally earn similar to university graduates.

It does not matter whether you are employed or not: your kids will get the same quality of schooling (almost no private schools), you get the same healthcare treatment everybody else gets, your kids will go to university for free - if they can’t afford living expenses the government will give them a free loan for that, you get 6 weeks of vacation and unlimited sick days.

THIS has nothing to do with Amazon, BMW, Google, Facebook or the holy church.

There is a divide - bit it’s not the “working classes” like Marx liked to predict but social/political systems.

Biologically, there are usually a complex history of reasons for an exhibited trait. It's important to remember tha sperm carry either a Y OR X gene expression, which inherently leads to more variability.

Human ovum undergo some mixing (https://genetics.thetech.org/ask-a-geneticist/odds-making-id...) but Human sperm are both more varied and larger quantity since they are more complex. The sperm both have to compete with each other and be acceptable by the ovum. -https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4071627/ (etc)

The actual payload of the sperm and ovum are roughly the same at ~8 million combinations for 8x8 million combinations for the fertilized ovum. -https://www.biology.iupui.edu/biocourses/N100H/ch9meiosis.ht...

So, the question implied by your casual comment is, what is the purpose of the multitude of sperm?

Is a multitude of sperm an evolutionary dead end (inefficiency)? Maybe, but there's no going back. The sperm faces quite a bit of natural resistance along it's fertilization journey. It's necessary, probably along the lines of the morphologically convoluted duck penises.

Is a multitude of sperm otherwise useful? Yes. It ensures a limit to the number of variations that can be passed on. If there are too many variations maybe the flagella will not be as efficient and loses to competition. -https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4242561/

Doss this directly contradict the idea of males having more variability? (posed by the previous paper). No. There are also environmental conditions (including seminal fluid involvement), temperature and the male/female bodies. Ovum are subjected to and less affected by environment than sperm, which likely is the source of greater variation overall. -https://jeb.biologists.org/content/218/1/107

There is also the nature of the disposability of sperm and the likelihood that there is less strict quality control, for a lack of better term, since competition solves inefficiencies on production quality. I could find nothing that indicates that this is a specific topic of study.
Interesting perspective. Could you please explain what do you mean by 'Netflixes'. What precisely they do and don't (in contrast with less successful companies)?
If you had an intended figure in terms of the median wage by employee class at AMZN, we could pretty easily get a good guess for that in terms of dollars and cents by looking at Glassdoor or Payscale. Conversely, you could provide the sort of median wage ratio you were thinking of, such that you'd be satisfied with Amazon's response; and we could compare them the other way around.

If you find the wording of GGP's question incorrect, can I ask what compensation level you would have preferred Amazon provide, either in absolute terms OR relative to some other measure?

> limited time [to] a small polynomial of the input size.

This is backwards; I meant that if you have any time bound whatsoever, the number of inputs you can inspect is limited to (a architecture-specific finite multiple of) the number of operations you can execute (because inspecting a input is such a operation).
You asked for a timestamp; I posted the specific segment. "Various options" includes injecting disinfectants.
Price can affect design decisions - i.e. the number of times you access backups for analysis can depend on takeout cost.
What We Learned from Pivoting into a DTC Business in Two Weeks
As someone who writes R daily, I’m really excited for 4.0. That said, R still leaves a lot to be desired. Changing the default for stringsAsFactors is great, and I think it reflects a small shift in R from being an exclusively stats-based language to something more general purpose. The nature of stringsAsFactors is that in most statistical models you need your categorical variables to be ordinal.

That said, R still is a stats language by design. In Python or JS for example, you can concatenate strings with ‘a’ + ‘b’ but the + operator in R is explicitly only for numeric types. R also has a horrible architecture for memory management, leading to code that uses profound amounts of RAM. I face this issue constantly as I work with very large datasets.

I have a love/hate relationship with R and despise using it in production. I’m also not a fan of the divergence that Tidyverse has caused. Particularly the expectation of Non-standard evaluation and the tendency for new R learners to become dependent on these packages. Especially as it relates to reproducibility and deploying code, these unnecessary dependencies suck. Tidyverse is maturing and breaking changes are still too common for comfort. There is no reason in my opinion to load stringr when a grep() will suffice. Or, to subset with select when [[ works perfectly fine. Or to filter when subsetting on a logical with which()... the list goes on. Tidyverse is essentially reinventing the wheel in many places. The biggest problem is that it doesn’t translate well to base-R in my experience with new programmers, leading to this divergence.

That said, piping with %>% and modifying directly with %<>%(via magrittr) is a pleasure that other languages I’ve worked with don’t manage as well.

And at the end of the day, I’m not going to rewrite implementations of all the latest statistical methods already written in R, and this is its strong suit. I’m increasingly using sophisticated spatial and spatiotemporal methods, and these methods are solely implemented in R.

I understand that R gets a lot of flack from software developers and I understand why. But, I also think it’s too often overlooked for its strong suits.
I do really disagree.

Given my experience with AWS, I doubt this is reliable in any way... Every bill I've ever seen(and paid personally for that matter) felt a bit like someone played darts blindfolded. One that really struck me (around 3 years ago when I decided to move over to gcp) was two consecutive months: my usage was 99.2% identical. First month my bill was around 151.01 euros. Second month it was 235.32. Everything was absolutely identical, API's usage, storage, traffic, everything. I compiled a report sent it over to their support and I got a convoluted response which could roughly be summarized with ¯\_(ツ)_/¯
This article mentions 300 people, which isn't a very big fraction of Amazon employees. I'm sure some employees who aren't participating sympathize, but what number would convince you that the "vast majority" think it's fine?
I didn't know what you meant. I thought you meant what you said. I'm grateful that the parent gave you a chance to clarify, and don't see this as a "derailment". Surely you aren't impugning their motive?
"Objectively" is not the right word here. There's a reason I used the word taste, rather than looking at specs or technology or performance: it might be that a $0.99 McDonald's hamburger is "objectively" inferior to a $20 organic grass-fed medium-rare burger from a fancy restaurant; but if I prefer the McDonald's one, it's useless to tell me that my tastes are wrong.

Maybe I like the ritual of thumb-to-unlock, since it feels more under my control. Maybe there's instances in which I want to look at the phone without unlocking the device. Maybe I hate the stupid notch, and I want my screen to be a rectangle and not a rounded rectangle. Just because you don't value these things doesn't make your preference "objectively" correct.

> wastes almost an inch of screen space to nothing

It's a feature, not a bug: https://en.wikipedia.org/wiki/Negative_space

(I also have a huge pet peeve with the bezels shrinking on recent iPads. However good the fancy touch-canceling algorithms get, they'll never compete with "I'm not touching the screen at all, so I'm 1000% sure this grip won't invoke an action.")

Yah, the idea that someone at WD thought it a good idea to put these kinds of drive in a RAID means that they don't technically understand RAID. Which is sort of scary, and makes you wonder what other gocha's they have lying about.

Even regular idle scrubbing is going to potentially keep drives 100% busy for extended periods of time. Combined with online backup/etc. Its crazy! Do they think that only enterprises run their NAS'es with backup, or workloads that provide a low level of near constant background activity?
It typically does. Most people are used to communicating in-person, often by chatting in casual interactions. Once you go remote, especially on a distributed team, individuals who are used to chatting in-person often don't have the discipline to send messages out to every member of a team. They typically also don't do multiple notifications (for example my company cross-posts announcements in both Slack and via email).
I'm so tired of this holier-than-thou "they should know better/be better prepared" bullshit. Once-in-a-century black swan event - yeah, every company should definitely have plans for something like this!

Moving massive resources in an effort like this is no small feat, and trying to treat it like it's as simple as signing people up to Slack is silly. It's amazing how people think operations like just magically manifest "because".

My point there was narrow: originally the word "troll" referred to intent (the intent to derail discussion, or whatever). But we can't observe intent, so that isn't a useable concept for moderation. If you try to moderate a site like HN and use the word "troll" in that original sense, people simply reply that it wasn't their intent to wreak havoc, as if that settles the issue. Actually it doesn't settle it. If someone starts a flamewar and the thread goes to hell, does it matter if they intended to? The house has burned down either way.

After a while it dawns on you (me) that whatever someone's inner state is when they post doesn't much matter anyhow—what matters are the observable effects that a post produces. Those are what we react to and base moderation on. When I say that a post was trollish I mean it had that sort of effect on the thread, intentionally or otherwise. I was hoping that linking to https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... would make this point clear and that I could get away with just referring to it, but maybe not.

This is a narrow point since it's about the use of a particular word, but it's a word that gets a rise out of people (ironically, I suppose?) and tends to make them feel like they're being personally deemed a "troll", when the point is about posts, not persons. I mostly use the word "flamebait" as a way to just avoid the issue.

Re "prioritization of civility above all else", that's not my view at all and it's a misrepresentation of how we moderate HN. If you said "prioritization of intellectual curiosity above all else", we would actually have something to discuss. Maybe you disagree that that should be the goal? Maybe you think we do a shitty job of it, in this case or even in every case? All that is fine, but being argued with about something that we neither think about nor try to do feels weirdly disconnecting.

"Not allowing anyone other than yourself to call out bullshit" strikes me as a bizarre thing to say. Users do that on HN all the time, which is why the site survives. We ask them to do it while remaining within the site guidelines, which is not only possible but more effective.

That paper looks interesting!

Yeah I mean the continuation bit is just inverted so 0=continue, 1=end-of-value. You can still count values efficiently with 1=continue, 0=end-of-value, but you have an extra subtraction at the end (`return number_of_bytes - number_of_bytes_with_top_bit_set;`)

Good point about not adding another format. I guess they want to avoid confusion.

The advice they are giving is to stop trusting methods, take the best practices that make sense, and trust your engineers to build a bespoke process from those building blocks.

SMR drives shouldn't be that slow. They're slower than PMR drives but it shouldn't be by so much that individual writes are taking tens of seconds.

What's probably happening is one of two things. Either the cache gets full and the drive is blocking while it flushes the cache to the disk, or the drive is advertising that it can do a large number of simultaneous write operations which it can't actually do all of in a reasonable amount of time when the cache is full, and then the ones queued last time out. In the first case they could have the firmware continue to process uncached writes when the cache is full, in the second case don't advertise the ability to do as many simultaneous writes.

Another alternative might be for the system to use a longer timeout value for these drives, but whether that's reasonable depends on how long it would actually have to be.

Brushing up COBOL skills. Once there were lots of projects which lots of IT companies took, to migrate from COBOL to JAVA, some were successful and some went back. COBOL is verbose, feels like writing English essay. Programs are huge todo, Java can reduce 25%-50% of code sometimes, python can reduce 90%(pythonic). What stands out, newer versions of COBOL will be upgraded and that old code will still work. New version is COBOL 6 : https://www.ibm.com/support/pages/cobol-v61-was-announced-wh...

This is a misconception borne of ignorance of the current state of VR tech.

Your statement was true for early VR seated games that used smooth locomotion or flight-sim-like games.

Roomscale VR games don't have motion sickness because of different locomotion methods (teleport, for instance... or they take place entirely within the room volume you have available). In fact, less motion sickness than you'd experience with a large monitor and something like a dynamic flight-based combat game. Unlike a monitor, your in-game view motion is mapped perfectly to physical head motion.

I've tried out about a dozen games, and the only time I had motion sickness at all was when I changed locomotion method from teleport to smooth in Rec Room.
Did you ever find a good modern Escape Velocity? I lost a lot of time to that game back in the day, and it's still one my favorites of all time.
I've actually taken an essentially opposite view, interestingly enough. As a younger person I read widely, rebelled in a very thoughtful way against my religion (in my opinion! haha!), took things very seriously, tried to really understand both atheism and other religions, etc. I think all of that was important. Through life experiences I've come to appreciate, strangely, the rituals of religion and the not-making-sense-ness of it. So I find it useful to consider the pre-baked objectives as a sort of rough draft I can push against, but more importantly, I've discarded the world view and taken the concrete. For Christianity, that's bread, wine, the holidays, the rhythm, the community, the directive to support charities generously. The concrete actions do something on a primordial level, as they're what my ancestors have done for oh about eight generations.

The actual pre-packaged beliefs? Meh. I'm less interested than I ever was in arguing the particulars of Paul with anyone. So, to summarize, for me religion is a reasonable place to get a default set of rituals and perhaps community, and long term that's the useful part because the rituals can continue even as my beliefs and circumstances change.

This may also be worth thinking about with respect to healthy eating, exercise, etc. Don't get sucked into a cult, but if signing up for (now-virtual) CrossFit or Pilates classes, or following Starting Strength, gets you doing something, it's a concrete physical ritual that can stay with you even as you change :)
What Went Down at the Virtual Druid Summit
The "asrs" mnemonics are the same, but the opcodes use different addressing modes. The 4th instruction in the longer sequence is a register-to-register move, which might be a simple register rename. It's not obvious to me that the shorter sequence is necessarily faster than the longer one.

OK, the "adds" is probably slower, and introduces a register dependency. But the whole exercise here is to test and see, not trust that some simple operation performs like how it looks.

Indeed, if you discount the "bx lr" (that's just the return, right?), the 1-instruction version takes 3ns, and the 4-instruction version takes 4ns. Clearly, 4 times as many instructions is not taking anywhere near 4 times as long to execute.

Coronavirus is spreading through rural South’s high-risk population
I would argue for people opening their doors and windows and shutting off their A/C as we enter early summer. But even where that's impractical, you're not likely to contract the disease outdoors at all. Besides heat, light, and humidity, there's a huge volume of air for particles to diffuse in. This limits your exposure by default, especially if you pair that with physical distancing.
This may be one of those cases where thinking about something explicitly is already half of the way to success.
I've found that a good way to show up in Google results is by writing the best content available on the web about a particular topic that people are likely to search for.

There's multiple avenues of research into this. Some more promising than others. He said, "it seems interesting to me", and left it at that. Nothing about that should strike anyone as inappropriate, when it was said for the sole purpose of trying to promote a guarded optimism around the matter. Too many seem to want to promote panic.
