My last writing professor didn't have a Wikipedia page, but he was fantastic, and taught with an approach on iteration: He allowed us to submit our assignments for review, and then let us take back the paper to work on it more, and we could continue to do that until it was an A paper.

This essentially guaranteed everyone an A in the course, if they did the work. But the focus was on getting you to improve your writing, not to fail people out. My opinion is that this is how writing should be taught, rather than giving you one shot to get a grade.

(I also once had a writing teacher who gave me a zero for a paper because it wasn't submitted in a manilla folder, and no late submissions were accepted, so I had no chance to fix it.)
End game for people like McConnell is that it puts downwards pressure on unions. A bankruptcy if a law is passed actually allowing states to go bankrupt would be a process overseen by federal courts, many of which are chaired by Trump appointed judges now. The judge gets to decide which debts are paid, meaning that pensions are very likely going to be chopped, hurting union members. There are other reasons.

Bottom line is that they want rich people (their primary donors) to get richer and don't care about poor or middle class. They are very open about it now and still somehow supported.

This is a good read on it:

If I were to listen,

If you were to listen.

I would hear that people don't want to be forced to choose between survival and health.

Losing your home, losing the ability to pay for healthcare, perhaps losing custody of your children or losing your already strained marriage -- these are all serious issues which may greatly impact the survival and health of many people.

One thing which tone-deafness is often a symptom of, is that one has lost a bit of the capacity to think of certain others as full, equal in worth, human beings. I know this from first hand experience.
Lyft is down ~34% since February
The adverse effects are concerning, however, the lancet trial was underpowered and had to be stopped early because there weren't enough patients [0]. That's why they say in their interpretation that even though they saw some numerical improvement in their results, larger trials are needed to evaluate statistical significance. The NIAID's trial is also a placebo-controlled randomized controlled trial and was adequately powered for reduction in recovery time, but didn't hit statistical significance at a p<.05 threshold for mortality rate.

In the long term I think this will be a solid move for both Uber & Lyft. The apparent economics of both businesses are relatively dire but the long term value prop is still as important as ever: they are generating the consumer data that will ultimately be used for self driving vehicles.

This will allow both companies to trim the fat and (hopefully) regain the move fast mentality that is necessary for a startup. This can be Uber and Lyfts time to shine.
Yes, agreed!

The tools are starting to get fairly good on Android. There’s a lot to like about Android Studio. But the actual platform APIs are still a mess.

Yes, this exists today, but what Amazon would be buying is faster time to expansion. If they need drivers now (which is an assumption, I don't know this to be a fact) Lyft gives them an established network incredibly fast.

So obviously the price would have to be right and of course Amazon wouldn't be paying a large premium.
This, this, this! It's been said elsewhere in these comments, but the term "micro"-services really do them a disservice, like it's expected that you need to break your application up into little pieces, to eliminate complexity. But many applications are inherently complex, and splitting them up isn't going to get you anywhere.

I've been trying to advocate for a "solar system model of services", where you have a big core application in the middle (the sun), surrounded by helper services of various kinds. Your important business logic can be left alone, but the database, other data stores, functions, timers, queues, integrations with third-party systems, one-off jobs, and other things can all stay in orbit.

There are benefits that you get from multiple services that you don't get from a monolith: having to rely on service discovery instead of hard-coding addresses or passwords, being unable to assume that the server your code is running on will live forever, and requiring a concrete CI-CD pipeline to get your code up-and-running are all good things to have, no matter your model, so it's important to have a clearly-defined process for them. A service-oriented architecture can give you that — put down the pickaxe, you don't need to split the monolith in two.

Back in 2016 Apache OpenOffice's PMC chair Dennis Hamilton proposed the idea of retiring the project (that's what Apache does to dead software projects).

Inevitably there was pushback from that community saying actually everything is fine, it's crazy to talk about retirement. Here's what I wrote in an LWN comment at that time:

> For example, shipping AOO 4.2 in 10 weeks at ApacheConEU. That's not crazy. Libreoffice goes from feature freeze to release in 10 weeks. A healthy AOO development community should be able to do it, or come so close as to leave no-one in any doubt.

I wrote that in September 2016. Hamilton is long gone and we're now much closer to 200 weeks than 10 weeks. AOO 4.2 still hasn't shipped. The "new" feature release they hope to release "later this year" (but they have said that most years) is stuff that wasn't cutting edge in 2016.

It's like Monty Python's Black Knight, refusing to admit defeat long after it ceases to be relevant. "It's just a scratch".

I disagree that this quarter will be a blip, but I agree with the sentiment here.

There are runways and parking lots in Washington full of undelivered planes which are waiting on contractual disputes related to the quality assurance of the 737 MAX issues. A significant percentage of Boeing planes are currently undeliverable and post-pandemic world airlines are likely going to cancel / downsize contracts or at least spend significant legal fees to attempt to do so.

Barring a quick and easy vaccination or herd immunity that accidentally happens much faster than expected, travel is unlikely to recover this year and perhaps not next. Clearing their backlog of planes will likely take 4+ years unless the company can convince people and airlines to trust them again.

The most interesting pattern I observed in my sleep is the integral patterns associated with it -- it's nearly impossible for me to wake up after less than 3.5 hours of sleep[1], and then after about 4 hours of sleep it becomes difficult again to wake up until after about 7.5 hours, when I usually wake up on my own, and then after around 8 hours of sleep if I oversleep you're probably not seeing me until I've finished a solid 11 hours.[0]

It's extraordinarily useful for planning when I am not getting much sleep. If I must be somewhere at X o'clock, and I can't get a full night's sleep for some reason, I make sure I am going to sleep so that my alarm starts going off when I am at around 3.5 hours of sleep or so. I've missed too many meetings and flights trying to get 5 or 6 hours of sleep. And if I've just pulled an all-nighter and need to be somewhere in 2 hours, I don't go to sleep unless I have someone who can literally kick me awake at the appropriate time, 'cuz nothing else is going to get it done.

[0] Yes, I've read enough about sleep to know most of the details behind such sleep rhythms.

Even if your house gets foreclosed on, they don't confiscate it; you still own whatever equity you have in it, so you get a check when it's sold. Yes, you don't build equity quickly at the start, but still it's better than the rental situation in this regard.
(speculative opinion here)

So...I've started to view the economy as a distributed voting algorithm where we decide what companies should exist and where people should spend their attention. If the fed is adding 6 trillion votes to the financial markets then won't that mean that we focus more of our attention on solving the problems of companies that either:

A) Are large enough to overcome the regulator hurdles to participate in financial markets.

B) Are explosively-growing enough to get VC funding.

C) Are underpriced enough to get private equity funding.

As a software engineer who's mostly worked for companies in category B, I guess I'm fine with this attention. But given what the pandemic is doing to small business, shouldn't society be preparing to devote more of its attention to companies solving problems like "I want some chicken & rice in Roxbury."?

If the country feels rudderless and without leadership, it is.

The top is, well, obviously, useless.

State leadership is all doing different things, which is, in some ways, a good thing, but I don't hear much in a concrete way about what the plan is to address this all over the next 12-18 months. We hear a lot about when we'll "open things back up" or phased re-openings, but nothing whatsoever about a strategy -- THESE are the tests we'll use, THIS antibody test to let people work THOSE jobs, THIS kind of contact tracing.

I'm not quite sure if the states are hoping the federal government will come out with some unifying strategy/process/materials/procedures at some point, or what, but it sure ain't happening.

> People get really gung-ho about reusing code and creating shared libraries, but reusing code is actually bad most of the time.

Disagree here, in general. I'm not in the ruby hyper-DRY camp, but copypasta is not the solution to dependency management problems.

Creating shared libraries does require discipline; you should do your best to just avoid breaking changes ever, and on the rare occasion you must, you need heavy communication and testing to ensure consumers find out about the change. And you can only change the API of the library; you can never incompatibly change how the library interacts with other services. I get that this is hard, but it's worthwhile if you can do it right.

We have thousands (maybe even tens of thousands) of lines of share library code at this point. Some of it is probably not necessary, but most of it we'd be completely lost without. Reimplementing core logic and utility classes and auth code over and over again is a great way to burn out your developers and create bugs. And these bugs are even worse than your garden-variety bugs, because you have to track them down and fix them over and over, and each fix is slightly different because each reimplementation is slightly different.

I agree that sometimes sharing code is a bad idea, but asserting it's bad "most of the time" is completely antithetical to my experience.

This is nice. I like how there's a switch that flips between design and testing, and how testing has the familiar insomnia view, with environments.

In the design view, I suggest having a way to show only part of the OpenAPI YAML spec, beyond code folding, because the full YAML document is a lot to scroll through. A way to jump from the view on the right side to the definition in the YAML spec is also important. I suggest adding triple dots at the end of each to show a menu, with "reveal in spec" or something like that.

This is very polished for an initial release. It's a better intro to OpenAPI for someone who is completely new to it than the SmartBear one. Congrats!
Let's say I have a hyperparameter optimization task where I have to tune a simulation to some spec by varying 2-4 input parameters, and the output is a single number. I have no analytical gradient, though it's probably OK to assume the domain is smooth. Each sim takes hours to run, the entire search could take days, and I would like something that works well in parallel so I can speed up the search. What's the state of art here? Are there anything close-to-state-of-art that's useable out of the box? I've read a few papers but they don't tend to come with software.
I have always difficulties understanding these kind of statements:

"appointment of civil servants or politicians to the supervisory board was unacceptable in the eyes of Lufthansa's executives."

Like, how is that any of executives' business who is on the supervisory board? If they do not like the money, find other investors, easy as that? It is almost like "ownership" is not a concept that should be associated with corporate shareholders at all, because it seems that the relationship between shareholders and corporation has very little resemblance of actual ownership.

Same thing applies to "hostile takeovers". What on earth is that? How come executives of the company I have shares at think they are anyhow entitled to have an opinion about me selling my shares to whom I want? None of their business whatsoever. If they want to have opinion, offer me better price.
It's not terrible. Plenty of people will happily take this, because they think they can get a new job quickly and pocket the buyout.
There are 8 photos in the article (not including the map); women are shown in 4 of those; there is exactly 1 photo where they focus on one woman at the front of a line in a parade (with multiple lines). To put that in perspective, there is also 1 photo that focuses on a man surrounded by men and women.

There are also 2 photos of one woman each, but they were just two of the people who were interviewed (and one of them was an instigator of the revolt). There no conjured narrative here that I can see. If every other source were saying that there were no women involved in the revolt, and the BBC were inserting women into the story, then it would be a conjured narrative, but that is not what is happening here.

The exceptions prove the rule. You can and do get irrational stock prices. Not everyone can follow the musk model, and if they did, investors would be back to using the fundamentals to differentiate them. If Boeing really thought they could follow the musk model, they would, but I personally don’t think they are in a good position to do so.

It might be straight-up politics. But there is a real situation where state governments have been financially mismanaged.

That is hilarious.

There was a time when saying black people where just as intelligent as white people was considered misinformation and a dangerous way to think.

Because the stock market going up or down is a proxy for changes in expectations about the future. If people are slightly less pessimistic than before, it will go up. Boeing being in dire straits is old news – it's all priced in, pretty much.

Besides, there are lots of news out there, including the fact that we're seeing stimulus that dwarfs even what was done during the '08-'09 crisis. Case in point, the top story at the WSJ website now is: https://www.wsj.com/articles/federal-reserve-interest-rates-...

In other words, when you recover from covid-19, you are immune to it. In other words, covid-19 is just like every other virus, in this respect.

Governments around the world have reacted with terror to this pandemic, but that doesn't mean the virus is some sort of strange monster. It's extremely infectious, and somewhat more lethal than influenza. That's all.

When I first heard about those patients who had recovered from the virus, and yet were still testing positive, it felt like a mistake. I'm glad it's been cleared up.
