This has a huge impact on the restaurants bottom line, but honestly, surprised the numbers aren't worse. I hope they can weather these bad times.
there’s plenty of other comments that explain it, but, CP/M, VAX, teletypewriters, punch cards - all used in-band control characters rather than an external signal
Are we talking about even roughly the same concept of functional purity [1]? Nothing is stopping a pure function from representing EOF as -1.

Implementing IO in a "pure" way, is however another discussion.

[1]: https://en.wikipedia.org/wiki/Pure_function
Not always, I think. But maybe there are some where it is common to me, although I do not remember, so I don't know.
In the beginning, there was the int. In K&R C, before function prototypes, all functions returned "int". ("float" and "double" were kludged in, without checking, at some point.)
So the character I/O functions returned a 16-bit signed int. There was no way to return a byte, or a "char". That allowed room for out of band signals such as EOF.

It's an artifact of that era. Along with "BREAK", which isn't a character either.

That’s interesting. I’d never heard of this place before and wasn’t aware of their history. Thanks for sharing.
Actually you just need to have them wear a mask and wipe down the equipment with standard hospital grade wipes. We know now that COVID-19 is not airborne and is spread by droplets only so this would be routine precautions, unlike TB which we scan routinely and is an airborne pathogen.

The problem with CT is we know that the test is completely normal in 50% of patients from day 0-2, and 10-15% of patients up to day 5, and roughly 7-10% of patients up to day 10. These numbers are probably an under representation given how few people with the illness get CT imaging.

Additionally as has been stated the findings are considered only somewhat specific, we believe that specificity will decrease as more and more people will eventually get scanned and prove our findings thus far to be false.

That is why we (in radiology) currently recommend against the routine use of CT in screening or diagnosis of COVID-19 related illness as a negative test does not mean anything and a positive test is usually noncontributory (clinical diagnosis of COVID-19 infection already made). Additionally, this will rarely affect clinical management. The only potential argument being made is the small subset of people who have viral pneumonia and may theoretically avoid being asked to self-quarantine however I highly doubt in the present climate any infectious patient with a cough will be allowed/think it wise to roam the streets.

China has also removed CT from their sixth edition diagnostic manual for this disease as an aside.

Right, one CT scan increases your lifetime risk of cancer 0.1%: https://www.scientificamerican.com/article/how-much-ct-scans...

Which isn't much for one person, but if you're CT scanning thousands of people, on average that's an extra case of cancer per thousand scanned.

The PCR test is probably more accurate and in the US, maybe even cheaper? Although it probably does have higher latency.
Good luck in two weeks.
Camostat is mentioned.
Sounds like an interesting low-tech solution. Can you explain a little more how this works? Is this with Outlook, Google Calendar or something else?

Throttle speeds after you've reached a very high threshold, maybe only during peak hours to avoid unnecessary underutilization. Why is that not one of your options?

Note that electrostatic coating per se is ancient. That part is certainly not what is new here.

https://en.wikipedia.org/wiki/Electrostatic_coating

I suspect the "electrostatic atomization" is just a consequence of the rotating cone head flinging particles of paint off its edge, which then end up pulled into the electrostatic field that is already there for the sake of electrostatic coating; i.e. that the main invention is the rotating head.
I've visited senators and representatives and they called me a threat to this country, to my face, knowing full well that I was a US citizen.

Maybe you've had less experience with politicians. Maybe you look less Asian. Maybe you're just naive. I can't know which it is, but I'm sure they think the same of you as me.
Despite the pres making this disaster worse in every way possible (cutting cdc funding, still not testing, still no quarantine, still no real action other than declaring this, way way way too fucking late with everything, hiding info, preventing states from testing, etc.) through the worst leadership one could imagine in such a situation, his idiot supporters are still likely to vote for him. And considering he'll likely run against Biden, a male Hillary, that increases his chances even more. The stupidity in this country is astounding.
The original headline read something more like “museum discovers all Dead Sea scroll fragments are forgeries,” which I read and initially thought “really? The Dead Sea scrolls are fake?” Then I read the article and realized it was only about a few fragments in some museum in DC, which I had never even heard of. So to me, the headline was much spicier than the article. It had grammatical ambiguity that I thought was a little misleading.
HTML/JavaScript. That has the shortest start-making-a-GUI story (plain JavaScript; React/Webpack/etc. absolutely do not have this level of accessibility).
I think I may still be banging my head on this one. It's just an ioctl difference between my pipe and my terminal's session, right?
I like the idea of throttling speeds during peak times only, and only after a certain amount of daily data use. That way neither low data users or offpeak users are penalised.
Biohackers Are on a Secret Hunt for the Coronavirus Vaccine [video]
Are you sure you aren’t mixing up CT and MRI? Our scheduled diagnostic CT slots are at every 15 minutes, of which probably 10 minutes are getting the patient on-off the table and positioned and 2 minutes are cleaning the room.

I do CT guided procedures every day. It’s seconds for data acquisition for any scanner made in the last 15 years. Even our ancient scanners from the early 2000s are this fast.
Hey Jowsie! Yes, currently the files are hosted on just on a public s3 bucket, so definitely not the most secure, but maybe something to add in the future.

I haven't heard of ShareX so will check that out and definitely look into a self-hosted option.
I guess what if the app needs to implement an "enhanced" paste that's different from the system default paste functionality?

I believe the photo picker has had a similar evolution. In the early days of iPhone OS apps used the system-default photo picker, and nowadays it's for apps to use that in favor of reimplementing.

Yes, maybe. For that to work, I guess you'd need the concepts (rooms etc.) to be similar enough, so that you can convert the control messages in a way that makes sense, and you'd need the media formats/chunking to be close enough.

It's not going to work 100%, as the Twilio API can do stuff that Jitsi doesn't (e.g. the choice of video being transferred p2p or via the server).

But if you're going to do that, then you're using Jitsi mainly for media transcoding/multiplexing. So maybe it would be easier to use that code in Jitsi directly and write a new API layer, rather than writing a shim above the existing API.
USB-C and the fast charging (well, power delivery negotiations) make USB condoms... tricky.
It is stupid. Instantaneous CFR is rarely knowable because of the problems of separating the infection data into groups of those who were infected simultaneously and tracking their ultimate resolution.
You realize that you're the racist here for pulling the race card, right? I'm not on your side just because you're Asian. I'm interested in the general well being of ALL people, Asian or not, in the US. I'm sorry you were mistreated, but you made a wrong assumption that I am, or that I will, and you're trying to get me to be on your "side"? I don't like presumptuous people.
I type `git pupll` an awful lot. No idea why.
No wonder so many programmers stick to boring business apps! ;-)

I got into coding qbasic (meh) & amiga (yeaaah) game engines in the 80s.

Currently teaching kids with Computercraft, to manipulate virtual worlds rather than boring spreadsheets.

IMO that sort of computer work will be obsolete by the time today’s kid are grown.

I’d probably avoid more than basic coding in general anymore and focus on math-y stuff. Just my take on where need will be, and discussing this with education researchers, and other thinkers.

I have a hard time believing we’ll carry as much code from the last couple decades as we had to from the previous few.

So much of it these days is web ui’s with a short shelf life relative to foundational code we shlepped forward in kernels, banking, and complex industry systems.
As a radiologist in a tertiary care centre operating CT scanners from four different manufacturers of various generations and age (0-20 years) I can assure you that there is no current CT protocol that requires minutes of active scanning time.

Even if you are using bolus tracking and a multiphase acquisition your actual scanning time will be far less than a minute.

We know in our centre the average patient time on the scanner is 10 minutes and we book patients every 15 minutes.
Why the Future of Data Analytics Is Prescriptive Analytics
A lot of Ethereum DeFi (and cryptocurrency in general) has been pretty frustrating to watch, because it's a lot of people with big ideas and little understanding of how to build stable financial systems.

In the case of Maker, what's interesting is that a stablecoin is actually possible. Maker has a really good core idea, several great elements to it:

1. The stablecoin is backed by collateral, typically a significant amount more collateral than the amount of stablecoin that has been issued.

2. People locking up collateral get greater exposure to Eth's volatility. So there's genuinely a reason to lock up collateral to issue stablecoins if you are bullish on Eth.

But, this breaks down a bit. There's no way to instantly convert the stablecoin back into the collateral asset, you have to find someone with a CDP who is willing to buy the stablecoin from you.

Similarly, there's no way to unlock your collateralized asset, you have to find someone who is willing to sell you the stablecoin in order to open up your vault and get your eth out.

So on both sides of the equation, you have this liquidity risk that doesn't really need to exist.

I could go on for a bit more, there are a bunch of other design decisions that are backwards and don't work well. But the fundamental ideas are actually pretty okay, and if you took a more traditional finance person and had them work through all the tiny details, I think you'd end up with something pretty powerful.

In that sense, it's almost like encryption. The tiniest detail being incorrect can make the whole construction useless, even if as a whole the fundamentals are pretty solid.
Interesting. It looks like it was just the less popular option. https://blog.mozilla.org/futurereleases/2019/01/24/clarifyin...
The extension seems great. But I don't see how would you monetize it from the home page. And if this get popular, how will you pay for the hosting and storage?
I think there's some imprecision in language going on here.

Yes, that page claims that the system efficiency of current state-of-the-art electrostatic coating booths is 95%, through a combination of electrostatic attraction and paint recovery equipment.

I think Toyota is saying that 95% of the paint ends up on the piece on the first pass.

But just to make things extra confusing, the source material for the Wikipedia page already has a section on rotary nozzles:

> Rotary atomizers are one of the possible methods of atomization used with electrostatic coating processes. Instead of air or fluid pressure, rotary atomizers use centrifugal force to atomize coating material. As a general rule of thumb, the faster the rotational speed, the greater the centrifugal force and the finer the atomization.

So I still have no idea what it is they're claiming.
I was working for Hughes, now Boeing Satellite Systems, for a couple of years doing Y2K remediation. I was writing ground station code that were on VAX/VMS, basically older hardware and software. So that thought did occur to me of satellites falling from the sky. From what I understand, everything worked out ok. There might be only one instance that we know of that was unanticipated when the year roll-over.
I'm in sales and every role I've held (a grand total of 2 tbf) has been a "be in the office if you need to be" type deal. Same as other people I know in it or other other positions I've considered.

If spending the weekend at a convention in another state is what's needed to make the sale I do that. If drinking with a visiting client until 2am is what's needed to make the sale I do that. If coming in to the office when there's no need and I might get sick and die and more importantly not be able to make sales, I don't do that.

"Sales" is a very broad role to the point where I think someone saying they do it is closer to someone saying they "make things" or "perform services" rather than "software developer" or "lawyer". It's more of a department than anything. Experiences working in it thus vary greatly.
Are you joking? This is the worst response to this crisis imaginable. It's impossible not to criticize the government for completely fucking everything up (already listed the top things in another post so I won't rehash). Nothing has been done. We've had a good six or more weeks and still nothing. It's a total disaster. That said, I think you're right about the election. People are too stupid to even be informed. but if we have a few hundred thousand or million deaths, who knows? I still doubt the fox news crowd will change their mind.
They thought they were risking 13% of their collateral in the event of a liquidation - not 100%. They were risking way more than they thought.
A flight is 12 hours. Considering it's a highly urgent need for a very unique circumstance... we're not shipping, IDK, keychains or something.
This is really cool. I can see how the e2e encryption could be super valuable. Thanks for suggesting!
If you use a browser with a Reader mode, it often works to enable Reader mode and then refresh the page.
Using the "file length" as opposed to the "EOF indicator" is like how strings can either be represented as pointer to a contiguous sequence of `char` ending with a NULL byte, or as a tuple of (length, pointer), without the needed NULL byte.

One gives a priori information the other a posteriori.
Isn't this a bit ironic that Tesla decided they offer the cybertruck in sheetmetal. As in every color you like as long as it's sheetmetal. Toyota has its own peak innovator dilemma moment here and they even brag about it.
On the other hand:

* No need to write a business case with fake ROI figures. No IT committee meeting. No need to teach a “solutions architect” who doesn’t really care to learn.

* Easier to evolve as requirements change because the front line person is fixing it.

* Proof of concept done already when you need IT involved for version control, security, etc.
Is it? If the American government were doing this, I would think the exact same thing. And America has in fact done similar things many times in the past.

Of course it's PR. It's always PR, probably regardless of what superpower's government is involved. The only difference here is that the Chinese government has more control over and knowledge of what private citizens are doing, so it can be difficult to disentangle private and governmental action.
Reminds me of this: https://m.youtube.com/watch?v=oDrYkwG6Tuo
Not efficiently. There's no "clipboard changed" notification on macOS.

Such a utility would have to run in the background and constantly query the clipboard. And since the clipboard basically holds a list of types and a way to ask the owning application for data, you'd have to keep waking up the clipboard owner, too, to ask it for data. Would you check every type it declares? Some applications support dozens of types.
I understand that nostalgia. You might enjoy playing with gambas: http://gambas.sourceforge.net/en/main.html

Or maybe Xojo: https://www.xojo.com/

I think Xojo was known as "RealBASIC" in the late 90s/early 00s and was really in the same spirit (but more cross platform) as VB6.

HyperCard occupies the same spot for me that VB6 seems to occupy for you. Today for stuff I'd have used that for in the 90s, I just stand up a quick little web app and text or email a link.

That's in no small part because nearly all of my wife's computing is done on an iThing and not on a computer that she could readily download and run something on. Unless I want to throw my cute GUI in an app store, it needs to be web-based now.

> The idea is that similar to how bluetooth and wifi labels help consumers feel confident their products will work with these wireless communication protocols, a Security label will instill confidence in consumers that their device is safe and secure according to standards.

I would like a warning label if the device requires an internet connection for normal operation or features that don't really need it, so I can decide not to buy it if the requirement is unreasonable.

“To help our students and their families, I have waived interest that all student loans held by federal government agencies, and that will be until further notice.”

This needs context. Interest rates will be temporarily waived for borrowers, but their monthly payments will not actually decrease, according to a Department of Education spokeswoman. Instead, borrowers’ full payments will go toward the principal on their loans.

Imagine putting your life savings into shitcoins.
The kernel returns EOF "if k is the current file position and m is the size of a file, performing a read() when k >= m..."

So, is the length of each file stored as an integer, along with the other metadata? This reminds me of how in JavaScript the length of an array is a property, instead of a function that counts it right then, like say in PHP.

Apparently it works. I've never heard of a situation where the file size number did not match the actual file size, nor of a time when the JavaScript array length got messed up. But it seems fragile. File operations would need to be ACID-compliant, like database operations (and likewise do JavaScript array operations). It seems like you would have to guard against race conditions.

Does anyone have a favorite resource that explains how such things are implemented safely?
Somehow, China must be held accountable for this. If it is permitted to externalize the foreseeable consequences of its hygiene and food safety norms, the rest of the world is just asking for covid20, covid21, ad nauseum.

Let’s not pretend that this isn’t just the latest in a long line of epidemics originating in China such as SARS, H1N1, H5N1, H7N9 and H3N2.
I'm flexible on monetization patterns for now, but if this were to take off, I'd imagine it'd be some sort of team-based pricing for teams heavily using it and introducing a collaboration-first experience.
While I actually find this discussion interesting (serious), I just want to make the note that this is a military system and thought was undoubtedly applied to making it resistant to at least trivial jamming approaches. Hence the PRNG based timing for the transmission.

It would be more compelling if you outlined some ways that that approach might be stymied and how the soviets might have counteracted that.
One day, about 5 years ago or so, I tried to login to my yahoo account that was still active at the time and I couldn't even login. They just said my account no longer exists! WTF! the account I had been using for over 10 years simply ceased to exist from one day to another. After that, I vowed to never use another yahoo product again.

I support this.

While we don’t know everything, and nothing is perfect, we have 2 contrasting outcomes: South Korea with drive through testing and Italy without it.

Instead of nitpicking numbers and facts, which we don’t have time for, go with those two data points.

Implement testing as fast as possible.
I don't know what d/c means but if it's data connection then the fact that light (and other EM energy like radio waves) travel faster in air would probably be a problem for using that as a jamming approach

Make a temporary federal law that overrides local laws. The federal government can basically do anything it wants. It is only because it is so gracious that it lets states have any laws at all.
From Japan with Love: it is irresponsible to go to a restaurant at this time.

A population's safety is worth more than a couple small businesses going into mothball mode. If you want to support said small business your task is clear: ensure 110% you and your family does not get infected. Risking infection just to "save" a business is an oxymoron. These businesses are at risk because of the infections, their pain will continue until the entire population treats the virus seriously and contains it.

If you want to help restaurants: stay home.

So now it just needs a little help from miners to actively exclude all other bidders.

My understanding is that in this case there were other bidders but they were drowned out by the winning bidder paying much more gas.
In some cases if you pay it off in less than 3-6 months the kickback doesn't happen.

Of course, there's nothing they can do at that point...
