Add to this Portrait in Jazz and Explorations.
I’ve been listening to those four albums very regularly for 6-7 years now. For a while I listened to at least one of the four each night.
I haven’t read White Fragility and couldn’t read the entirety of the article linked here due to the paywall, so I cannot comment on those.
I have been trying to educate myself about the topic recently, though, and would strongly recommend looking into some of the excellent work on systemic racism in the US if you’re interested in learning more.
The documentary “13th” (available for free on YouTube at the moment), the 2nd season of the podcast Scene On Radio (“Seeing White”), and the book How to Be An Anti-Racist are three things I can recommend based on what I’ve read/heard from them so far.
What you’re calling the “recent forced redefinition of racism” is not especially recent. I first heard this argument around 30 years ago, and at the time dismissed it, but now understand why people want to emphasize that over the definition I recall learning as a child which was structured along the lines of a belief in superiority of one group over another.
Having a belief may impact how you feel towards someone and how you act towards them, and may even have an impact on that person if you are in a position to influence the course of their life.
Having a system that is designed and reinforced to encourage disparate outcomes is far more impactful to that group as a whole.
I’m not going to argue that both aren’t harmful, but I’ve certainly come around to the conclusion that systematic or policy-based racism (if you’re uncomfortable calling it racism, feel free to disregard the name and come up with something you’re more comfortable with) has disproportionately affected Black and non-black people of color in the US.
Yes that’s one thing this bird would do. The whole cycle of two or three repetitive sounds from an alarm before moving to another song.
Yes you’re right. Judging by Wikipedia it seems likely it was a northern mockingbird.
I spent two summers in an apartment in San Francisco that was near the nest of what I assume was a nightingale.
Every night around midnight it would start singing. It would loop through maybe 8 songs. Some of them sounded very much like the local environment. For example one song was pretty much identical to sirens that I would periodically hear.
It would last for an hour or two each night. I don’t know where the bird went the rest of the year. That was almost ten years ago and I still miss falling asleep to that.
Not a lot of good fried food here.
I have only found one reasonably good fried fish place and most of the french fries in the area aren’t great.
This is something I’ve seen called “butts-in-seats management”, and yes, I’ve seen it in practice.
Many years ago I had a new skip-level manager who emailed me one day saying that he had dropped by my office a few times to introduce himself but I was never around and he was really concerned with the fact that I never seemed to be in my office working. I am relatively certain every time he dropped by I was either in a colleagues office discussing a work issue or had run down to grab a coffee. But to him this was “concerning”.
He didn’t last long. I believe he moved on in 8-12 months.
Also happening in one small section of the Mission in SF: https://www.sfchronicle.com/health/article/Why-everyone-in-B...
The SF Bay Area has a population that is 75% of Sweden’s entire population.
SF itself is more densely populated than Sweden’s most densely populated city which appears to be Stockholm (7700/km^2 vs 5000/km^2). Stockholm has a population around 20% larger than SF.
According to Wikipedia, California is smaller than Sweden.
So there may be some dense pockets in Sweden but it certainly isn’t more densely populated than California and it doesn’t appear that there are large cities that approach the density of NYC/SF.
Sweden has 1/4th the population of California. It looks like the total deaths is around 50% higher than California although of course California might have deaths that should have been attributed to COVID-19 that weren’t.
It looks like it was estimated to have arrived in Sweden two days earlier.
This was updated April 4: https://www.cdc.gov/coronavirus/2019-ncov/covid-data/covidvi...
“The percentage of deaths attributed to pneumonia and influenza is 8.2% which is above the epidemic threshold of 7.2%. Deaths due to pneumonia have increased sharply since the end of February, while those due to influenza increased modestly through early March and declined this week. Deaths attributed specifically to COVID-19 will be reported next week.”
Okay I’ll complain.
I work in industry in a position where having access to papers is very helpful, some would say essential.
I have access to IEEE and ACM DLs. I don’t, however, have access to myriad papers from other organizations like Elsevier or Springer Verlag. These are often cited by papers on IEEE/ACM DLs. Some are from 20-40 years ago and still very relevant and interesting.
I have yet to find a way to get access to these in a predictable manner (yes, sometimes you can find preprints or old PostScript versions on various authors academic websites, but not generally).
Often the contents are from government sponsored research from the US government and possibly other governments (if only through their support of Universities in their country).
Assuming you’re referring to my comment:
wait another day or so for the exterior surface to become safe.
Unless you think that for some reason the exterior of the box is going to have live virus for more than what’s been reported, this seems reasonable.
Order a bunch of water and TP
The TP makes sense. I don't understand why you're suggesting to order water, though.
Can you elaborate?
I haven't seen any recommendations that tap water would be unsafe.
If you're in an earthquake prone zone like SF or LA of course having water at home is a very good idea any time of the year.
If you receive packages let them sit somewhere for 2 days before opening
I am curious if you have a source for the two day number.
I have seen various reports ranging from 12-24 hours for how long this particular virus can last on surfaces like cardboard. The longest estimate I have seen for any surface is 72 hours for stainless steel under lab conditions (i.e. not real-world conditions).
So presumably if it takes 2-3 days for a package to arrive, the contents should be okay if you wait another day or so for the exterior surface to become safe.
There have been several reports going back at least a few months of a coyote wandering around Noe Valley at dusk, I think around 25th & Sanchez or that general area.
So this isn’t new although perhaps more are venturing out for longer periods of time due to the streets being emptier.
WHO: https://news.yahoo.com/avoid-taking-ibuprofen-covid-19-sympt...
Asked about the study, WHO spokesman Christian Lindmeier told reporters in Geneva the UN health agency's experts were "looking into this to give further guidance."
"In the meantime, we recommend using rather paracetamol, and do not use ibuprofen as a self-medication. That's important," he said.
Paracetamol = acetaminophen: https://www.drugs.com/paracetamol.html
Not if it’s a library that you’re not compiling, like language runtimes or system libraries.
LTO requires that you’re compiling all the code to get the benefits.
I’m also not sure if either gcc or clang’s LTO does layout at the basic block level or at the function level. There is a lot of benefit from doing it at the basic block level. You can literally lay out all the code that runs at application start time so that it is mostly adjacent and fall-through from block to block during execution.
This isn’t something you necessarily do instead of LTO, but rather something you can do in addition to it.
Because if you statically link libraries like the language runtime it allows you to reorder the blocks in those as well to improve locality and instruction cache utilization.
For example if your code calls a particular runtime function shortly after starting, that function (or the basic blocks from that function that are executed frequently) can be placed close to the call site.
What are you guys up to these days?
Practicing the piano. I’ve been playing for around three months.
Sometimes it’s nice to step away from the computer keyboard.
H1N1 had an R0 between 1.4 and 1.6 [1]. Let's assume it was 1.6.
Let's assume that the current coronavirus has an R0 of just 2 (estimates vary, most higher than this). Perhaps it is less, but for the sake of argument lets say it's 2.
1.6^10 = ~110
2^10 = 1024 (so ~9x higher)
That's with just 10 steps of transmission. So assuming the R0 of 2 is correct this will spread much faster.
Now consider that people do not seem to show symptoms until at least 5 days after they've been exposed (by some estimates, even longer, like 9+ days). Assuming they are contagious at least part of that time, they are unknowingly spreading this.
As others have mentioned add into it the fact that people who have been exposed to various flu viruses can have some immunity to new ones.
Ignoring all that, just look what's actually happening on the ground in Italy and China.
To be clear, this is the worst-case estimate for the current coronavirus outbreak in the US, not the worst-case estimate for the 2009 H1N1 flu outbreak.
I’m reminded of this:
https://news.artnet.com/art-world/mexican-museums-artifacts-...
The report found that only 83 of 2,000—or just over four percent—of the museum's pre-Columbian artifacts could be authenticated.
Slowing things down is important in order to keep the medical system from being overwhelmed.
We already know we don’t have enough ventilators or enough staff to care for the ill if we end up with a similar growth curve to what they’ve seen in Italy.
They may be insured. However they may also have a large deductible and need to eat quite a few costs.
Sorry to hear that and hope it’s not too stressful!

It probably depends on your circle of friends and acquaintances but for at least a decade in text messages and social networks I have seen people use airport designations in place of the city they represent. For example,
“Spending next weekend in SEA then staying with friends in MPS before returning home to SFO.”
So no, SFO is not only ever unambiguously the airport.
I believe the combination of more frequent flying, booking tickets ourselves online (rather than by telephone) and increased communication on devices have combined to result in this quirk of language.
I think what people usually mean in these situations is that you’re forced to think about the error.
Programs in C (and many other languages) have the problem that you can ignore errors accidentally.
Exceptions “solve” this by forcing some level of your stack to at least acknowledge that an error occurred. The problem with that model is that you still don’t have to think at any given level of the call stack what the appropriate handling is for any kind of error. You can just let it propagate up further, deferring responsibility.
For some code that might actually be appropriate, but often it results in code higher up that cannot possibly know how to deal with every error that can happen farther down the call stack just swallowing errors.
One thing I frequently see is mixing validation code with processing logic. By separating the two you can have the validation code deal with errors and the logic simply assert that it’s input is good (because it should have been validated by the error handling code before being passed in).
I think models where you are forced to think about errors at each level but have a simple mechanism to make them propagate up are probably the best single model if you have to choose one model for a language.
In any event, error handling is difficult and frequently doesn’t get the attention it deserves in the design and implementation of libraries and large systems.
I wouldn’t consider this a leaky abstraction.
Floating point numbers are explicitly not trying to be an abstraction for real numbers, but rather an approximation for them that is good enough for most purposes (if you’re careful in how you use them).
That they might not be taught as such is another problem.
