You haven't flown on any of the Asian national carriers, have you? They are all better than any American carrier. They are all better value than any American carriers other than the "discount" brands like Southwest. USA domestic air travel would improve dramatically if they were allowed to compete here.

Hi Justin, I work at Heroku for Salesforce. I'm unsure if you've worked with anyone here in the past (like on our older app.yml, heroku.yml and constellations, etc stuff). But I just wanted to say thanks for establishing a standard for this and helping the rest of us in this space continue to evolve.
Note that this is similar to how for example MPEG does it with the intermediate frames and motion vectors. First it encodes a full frame using basically regular JPEG, then for the next frames it first does motion estimation by splitting the image into 8x8 blocks and then for each block it tries to find the position in the previous frame which best fits it. The difference in position is called the motion vector for that block.

It can then take all the "best fit" block from the previous frame and use it to generate a prediction of the next frame. It then computes the difference between the prediction and the actual frame, and stores this difference along with the set of motion vectors used to generate the prediction image.

If nothing much has changed, just camera moving a bit about, the difference between the prediction and the actual frame data is very small and can be easily compressed. Also, the range of the motion vectors is typically limited to +/-16 pixels, and you only need one per block, so they take up very little space.
Firstname lastname is too fragile and oversimplified. Suffix, prefix and a variable number of middle names/initials can also be necessary. Occasionally, legal name vs. nickname is also needed. But if there's no pressing need for grouping or sorting by surname, why piecemeal any of it out?

These three books helped me tremendously:

1. The Pragmatic Programmer by Andy Hunt and Dave Thomas

2. The Clean Coder by Robert Martin

3. Design Patterns: Elements of Reusable Object-Oriented Software (the "Gang of Four" book)

The first two contain a range of advice pertaining to working as a professional software engineer. The third one, although very dated, is still a great resource for understanding many of the design patterns used in OOP.
It also fostered distrust among anyone able to see the elementary contradictions in their arguments.
Thanks for letting me know about the site!

This is a test to see if someone has a current COVID-19 infection. The antibody tests (serological) tests are also important, but since it is estimated that only ~1% of the US has previously contracted COVID-19, it will be a while before serological testing becomes useful at a population level.

Our initial data show no false-positives and no false-negatives out of all specimens assayed. However, it is early days still and none of the leading tests have real-world data on false-positive and false-negative rates. The crucial parameter here to compare test performance is limit of detection (LOD). We showed we could detect as few as 10 molecules of virus, which is on par with the best RT-qPCR tests.

Cost is definitely an important consideration for roll-out of a widespread test. We anticipate that the cost will be about $15 per test.

I very much disagree. While the shelter-at-home, extreme social distancing regulations may relax, I'm guessing there will be a large percentage of people who will not want to be packed in, in a shared working environment, for at least a year.

I don't think everyone will leave, but business will be way down, and WeWork was marginal in the best of times. It is 100%, completely dead. The only question is how long it will be able to go along in "zombie" status given existing capital and US govt loans.
Thanks for your efforts! Inspiring to see our broader community spring into action.

I was part of a volunteer team that tested 3400 people on Friday/Saturday in Santa Clara country for COVID-19 antibodies [1]. It took a team of 100+ volunteers 10 hours / day just to collect samples.

Stanford, for example, has plenty of automated testing capacity, and even reagents. IMHO, the limiting factors are not that we need new tests, but rather we need (1) lighter regulations (2) funding to buy supplies and (3) massive manpower to scale-up drive through testing

you've listed some skills that you can bring to bear to a problem, but what are example problems you're trying to solve? i'd think that with most small businesses closed, they'd be hard to help right now for instance.

it'd probably help to list some of the kinds of projects you imagine so that folks who need help/want to give help can decide to do so (or not).

for instance, could you use product, project, or general management help? legal skills? do you want to work with government agencies? medical ones? non-profits? how about tenant's rights organizations? etc.

Anyone that ever had close contact to what the UN does, knows that it is a corrupt, inefficient and grossly incompetent organisation, filled with cousins of African strongmen and other connected people. Same goes for people working in NGOs cooperating with the UN, a common arrangement for example in Geneva is that while the partner works as an oil broker, the other writes position papers on women's rights and observes meetings that has half of the members of the subcommittee asleep.

I am on board with this stack 100% and have been recommending Mattermost myself. Imagine my disappointment when I found out that Mattermost, even the self-hosted one, is spyware.

They call it "Diagnostics" to hide its true purpose, but really it's phone-home. Silently and with no notification, on f/oss self-hosted software; it's really a letdown.

To disable it, you must use the following entirely undocumented environment variables:

MM_LOGSETTINGS_ENABLEDIAGNOSTICS=false
MM_SERVICESETTINGS_ENABLESECURITYFIXALERT=false

I go the further step of using a small Dockerfile that contains the following to patch the binary itself:

>Our initial data show no false-positives and no false-negatives out of all specimens assayed.

Your test is perfect? Color me skeptical.
You just completely prove my point.

First there’s the “almost 100%” of scientists agree argument again. Sorry, that’s not a valid argument for saying something is true!

Second. Models aren’t proof. They’re models. Yes we can measure gas quantities and determine correlations. But we haven’t scientifically proven it. We’re dealing with chaotic systems. Until we can, we need to remain skeptical and open to other ideas. That’s my point. Not that it isn’t happening.

Third. Then you bring politics into it. Oh the 1% are funded by Big Oil. Oh and the 99% aren’t funded by politically motivated players either? See point (1), scientific fact isn’t determined by who agrees with it or not. Until it’s proven, it may be unproven.

And fourth. Flat earth, again, the relationship to climate deniers...you don’t need scientists to agree the world isn’t flat. It’s proven. Scientifically. See the difference?

So, I can't get to your site, but this seems a little disingenuous as a title. You're not seemingly "unlocking" anything more than a protocol for Sanger sequencing that, if it eventually was approved and actually tested against real samples and people elsewhere adapted the protocols to use for testing, you would then... at that point... unlock a thing.
You are correct that the dividend amount also depends on Amica's claim payouts for the preceding 12 months, however I checked my statement from last year's payout and it lists a dividend percentage for each type of policy they sell, ranging from NONE (Automobile Liability and Physical Damage, Homeowners (Workers Comp)) to 20% (Boat/Yacht, Personal Umbrella Liability), so this seems to be a separate factor from their claim payouts for the preceding 12 months and also separate from the multi-policy premium discounts they offer. I will also add that these rates can also vary by state, as the statement specifically says "our latest rates in Texas". Based on what I'm seeing I wouldn't expect an increase in the annual dividend due to fewer car accidents, but a premium reduction might be possible.
> Current tax incentives push companies to spend money (allocate it to productive areas) as much as possible or git hit with corporate income taxes.

Basic profit-seeking capitalism incentivizes companies to either invest in productive areas or to return capital to shareholders so shareholders can invest in more productive areas. Taxes only effect those incentives at the margins, and the past several decades of increasingly corporate-friendly tax reforms don't excuse or justify the decisions that have been made by CFOs.

> If a company is operating efficiently, they wouldn’t be turning a profit

But what's the timeline for gauging efficiency? Any company needing a public bailout even though they had sufficient profit to cover the issue is manifestly not operating very efficiently. The ones taking on debt to fund buybacks are beyond any sort of reasonable justification from a public policy perspective.

We can quibble over the scope of unpredictable downturns, but AFAIU the airlines returned much more capital than would be reasonable in expectations of a 10-year event. 1980s deregulation, 9/11, 2008 recession, and now 2020 pandemic... at some point you can't say that this stuff is "unpredictable" with a straight face. Something always happens, and even if you don't know precisely what or when, it's regular enough that you can substantially insure yourself. There's obvious moral hazard at play here, even though some public support may have been justifiable in this particular case.

Even worse, AFAIU once upon a time airline union retirement funds were major purchasers of airline bonds. There was a sort of quid pro at play that more closely aligned unions and airlines during downturns, as unions were more incentivized than usual to return the airline to profitability through cost-cutting measures. The downside was, at least hypothetically, greater moral hazard--more pressure for government bailouts because more low- and middle-class employees were effected. But these days airlines have increasingly spurned unions and these sorts of arrangements, so any bailout directly lines the pockets of wealthy investors. There should be much less urgency to bailout the industry, especially without an equity exchange.

They could have paid off debts. I am pretty sure some even use debt to purchase stocks in their buy back programs. I don’t get why we are bailing them out. 60% of people down own a single share stock including 401Ks, IRAs etc. Adding some much liquidity into the economy through q-easing will increase inflation in the long run and harm the middle the class.
I'm sorry but this is wrong: "The assertion that beta reduction (i.e. evaluation) does not rely on type information and types are overlaid on top is precisely the heart of Curry semantics."

Beta reduction is not affected by types ascribed to terms. The crucial difference between Church and Curry is that Curry allows each term to be ascribed a set of types - perhaps 0, 1 or many - whereas Church insists on each term having exactly one (often annotated). That is all. Both are systems for proving type correctness of terms, and are no more than that.

Sample collection and accessioning (accessioning is unpacking test tubes one by one and aliquoting them into plates in the lab) is definitely going to require a lot of manpower. I'm hopeful that patients "self swabbing" can help alleviate some of the manpower needs. (Self-swabs are not allowed currently under FDA guidance).
There was a lot of interesting promise in Web 2.0 that was completely wasted and then died. I think a big part of the problem was even things like Yahoo Pipes were too complicated for a lot of people and anyone trying to use third party APIs for commercial purposes ran afoul of EULAs or just plain old rent seeking. Once privacy invading advertising became the norm APIs were further restricted or discontinued because the user wasn't running a bunch of client side code tracking and scraping all their behavior on a web page.

It didn't help that a lot of Web 2.0 darlings sold out to on-the-way-out Web 1.0 companies \cough\Yahoo\cough\. Yahoo's management couldn't even monetize money, let alone Web 2.0 properties. So instead we got social media silos. You can put stuff in but good luck ever getting it out. You can share it with whomever so long as they also join the same silo.

Moreover, now is actually a good time to buy fuel and stockpile it (if they have the facilities), or use derivatives to take advantage of the situation if not. I am aware that airlines do hedge their fuel costs, but, that requires cash, which they apparently don't have right now.

I have also observed people suggest a statistically special N, but this is a misconception. There is no special N. There is only a relationship between increasing N and a monotonic increase in the confidence in your result. Most scientific standards specify a "confidence" of at least 95%, but if you are willing to accept more uncertainty--perhaps because there is a large upside to a positive result--then you can make due with a smaller sample.
