Lots of people are reporting on this - I'm not sure where you're looking that you're missing it.
Yes, ok. But this doesn't say it's a bad tool? Only a not very used tool? (I know that you've not claimed neither; only that is not a very used tool)
I don't really believe this although it seems rather hard to prove which side of this debate is right. Presumably it also depends on circumstances. I think any sort of messy or bad code immediately slows down developers. The truism that code is more often read than written comes to mind. This 'devivering business value' thing also sounds doubtful to me. Any sort of bad code is a breeding ground of bugs. So you have completed three stories this sprint and hence delivered three items of 'business value'? Sounds nice but it may not be so great if two of them are going to break in the near future because of code quality issues. In that case it maybe is just not true that three items of business value were delivered. In the context of bad coding practices it kind of becomes unknowable how many items of business value were delivered.

I kind of despise the term 'technical debt'. It seems that in the beginning it was introduced to make the business side take code quality issues more seriously by likening them to something they could understand, i.e., debt, but now it seems to function as a way to postpone the fixing of issues, perhaps indefinitely. I think most things that go under the moniker of technical debt have an interest rate that is far higher than any business would enjoy taking out in terms of a loan.

Let me give an example. Some code can be badly formatted. This hardly costs any time to correct but maybe it is also not worth it? Well, I once encountered some code that clearly was in the wrong function, so I asked the colleague who tends to know about that part of the application. Then it turned out it actually was not in the wrong function but instead there was no blank line between the two functions making me not notice that it was actually two function instead of one. In the mean time I had disturbed a colleague which also has a real cost in terms of getting back into whatever he was busy doing. All code quality issues have costs associated to them that are very difficult to know beforehand but I think the safer way is to always be improving code quality and that which is called the internal quality of software should actually just be maximalized and that technical debt most of the time has more costs than benefits and that the costs will come sooner than anyone expects, long before you MVP is actually finished so that you might actually have paid it off profitably beforehand.
>S-curves have only three parameters, and so it is perhaps impressive that they fit a variety of systems so well

no it does not. it just so happens that the solution of certain differential equations produces an s-shape. it has nothing to do with having only 3 parameters. Very sophisticated models with many of parameters and conditions can produce this shape.
> he cares about getting the respect of his peer group & broader society. He’s not going to earn money off this, he’s going to earn respect.

Whatever the case, you have to admit that you are taking for granted that his intentions are benign. There's no rule that billionaires have to be benevolent. There's a lot of soft power associated with a mandatory vaccination program but aside from that, the chipping that he is behind has an enormous (and dangerous) surveillance potential.

The man has the clout and resources to potentially install a physical, nonremovable beacon into people's bodies, and has spoken openly and repeatedly about doing so. How do you know he won't get drunk with that kind of power? A single man could, say, sway elections if he had access to just the location data for 300MM Americans. And there's really no way we'd know if the biometric/location data were being siphoned for "non government" use...
Yes, that is the main issue with our strategy in Sweden. We failed to keep it away from seniors' homes. The strategy seems to have worked just fine otherwise. It stopped our hospitals from getting overwhelmed, espcially since we managed to contain it in Stockholm for the most part. But we did not have resources to test people working with the elderly.
Currently we have no idea how many people have had covid. We have a good idea how many have died, but no country has managed to do the kind of testing that would give a good indication of how many people have been infected. Do 2% of people getting it die, or 0.2%, or 0.02%? Testing 1 million people at random across the country will give good results of not only how deadly it is, but also how likely it is to spread in different areas of the country.
1. You can't put GPL'd apps on the Apple App Store, because the terms conflict. For instance, you cannot redistribute an app you've received from the App Store. (At best you can use code with a specific waiver e.g. https://github.com/mobile-shell/mosh/blob/master/COPYING.iOS .)

2. It seems a tiny bit optimistic to expect a malicious government to abide by copyright law.

I think the goal of making this open-source is to enable third-party review to avoid innocent mistakes, not to allow you to audit that the code hasn't been maliciously and intentionally modified. There isn't a great way to audit that the binary you download from the App Store matches specific source, for instance.

It's important to note that some colleges restrict the number of credits you can take/earn during the time between high school graduation and college matriculation.

My alma mater, Purdue, permits incoming freshmen to take a gap year (but not purely due to Coronavirus [0]). During that year, the would-be freshmen may not take >=12 credit hours of courses or else their admission will be rescinded and the freshmen would be required to reapply as a transfer student [1].

Very surprised to find out country (city) in HN's top page!

For people who are interested in current Korea's situation:

There were 18 new cases two days ago, and 8 new cases yesterday.
The number of new cases have been consistently falling since April 14th.
'Intense social distancing' was stopped yesterday (April 19th),
and the Korean government is planning to drop the 'social distancing' policy on May 5th.

Schools are planned to open on May 6th, and the ban of churches, bars, etc. are expected to be dropped in the following days (probably tomorrow).

The KCDC is saying that to drop the 'social distancing',
there should consistently have less than 30 cases (which is true for a week)
and cases which infection routes are unknown should be less than 5% of all new cases.
(It was about 5%~10% when it was announced, and AFAIK it's now true.)

There's still some anxiety because people started to become dull to the social distancing movement - so people are worrying that new cases might increase.
> The way to protect secure hardware tokens is not bitstream encryption, it's tamper protection. You store the key material in SRAM that is erased when the device detects any attempt at manipulating.

You need both. First, make all external storage (that hold keys, firmware, configurations) unreadable to everything else besides the main processor itself. Also, in the ideal world, implement tamper detection, in most HSMs there are tamper detections, but unfortunately, the world is not ideal, in the FOSS world, I don't see anything that uses tamper detection, developing an open source tamper detection is something has great value to the community, yet, I don't see it happening at anytime soon. Also, the majority of security token/hardware have no tamper detection - SIM cards, bank cards, OpenPGP cards (Yubikeys, Nitrokeys), smartphones, they only depend on encrypting external storage and/or restrict the access of the secret inside a chip to maintain security. In practice, they still have an above-average security level, it clears shows tamper protection is not the only way to protection the hardware, although it's less effective and occasionally something is going to be broken, to be sure.

This specific FPGA bitstream encryption vulnerability may be a non-issue, as pointed out by the critics, relying on external storage is not a good idea to begin with, better to burn everything inside the FPGA. My point is that FPGAs are the only platform to implement FOSS security hardware in the most (relatively) transparent and secure manner, yet, the recent discoveries of FPGAs vulnerabilities indicates they are much less secure than expected, and it's only the tip of an iceberg. If external bitstream encryption has cryptographic vulnerabilities, what comes next? More broken cryptos that allow you to read an internal key?
I read his "Age of Extremes"[1], and thought his point that there was an awful lot of Socialism going on in the U.S. system was a cogent one.

Arguably he averted his gaze from some of the excesses at the other end of the argument.

Not having enough support is the only reason he lost. The DNC didn't go in and tamper votes.

I've seen many sanders supporters get upset over things that they perceive as unfair like how candidates dropped out to stop splitting the vote.

Every single candidate has had complaints about being treated unfairly. People were calling joe's campaign dead in the water. Yang got upset enough that he called out networks in a very public manner.

And yea, Sanders wasn't supported by the establishment. But like we've seen with Trump, the establishment doesn't matter if the candidate has real support. Obama was a no name senator that beat the most establishment character ever because he had that support.

Sanders had a lot of problems as a candidate, and those are the real reasons that he lost rather than conspiracy theories about machinations by the elite.
Short term, calorie deficit will deplete the immune system. But long term getting to a healthy weight and less diabetic will make you less susceptible to SARS2.
We won't be sure of such statistics whether or not we have widespread testing. Even for pandemics in the past, we just don't know how many people caught them, not even a single significant digit. The best we can do is make reasoned guesses based on the available evidence.

one world standard is not the same as one world government.

one world full bureaucrats regulate-everything-to-death government is a dystopian nightmare.

"Were we directed from Washington when to sow, and when to reap, we should soon want bread" --Thomas Jefferson

If they're making the same claim I've seen elsewhere: People who would have died anyway from cancer/heart attacks but also have COVID19 are getting counted as COVID19 deaths instead of other causes, causing a dip in those numbers.
As the paper explains, there is no "signing" involved (in the sense of a public-key cryptosystem).

Each encrypted bitstream includes an HMAC, but because the HMAC key is part of the encrypted bitstream itself, it basically only acts like a non-cryptographic checksum. An attacker who knows the encryption key can simply choose an arbitrary HMAC key and generate a valid HMAC for arbitrary data.

EDIT: I should clarify that this attack doesn't appear to actually let someone extract the AES encryption key. But they can use an FPGA that has the key programmed as a decryption oracle. And a weakness of CBC mode is that a decryption oracle can be used for encryption as well.
“Smooth” is a term of art in math that means continuously differentiable infinitely many times. These functions are a subset of those functions that are differentiable once.

Differentiable once means, by definition, approximable everywhere by a line at small enough scale.

This is an ancient understanding though, it ignores aerosol transmission. But you are still correct that outside is safe, there is absolutely no need to restrict it at all, it's confined poorly ventilated spaces that are a problem, like almost any building, cars, buses, planes, where the virus can concentrate in the air and close range contact isn't even needed, just breathing such air is bad enough. Wearing a mask is the only thing that helps to not get infected in such situations, but doesn't actually help much when infected people are wearing them, they still contaminate the air with aerosol.
Sounds like an artificial zeolite.

By the time it is fall, this professor's advice will be obsolete. The death rate is already slowing down in NYC and Italy. The curve is flattened in South Korea and China, and there, many are going outside to cafes and the Han River park. San Francisco has had a grand total of 20 deaths. US is already planning to gradually reopen the economy.

On a per capita basis yes, but the US has done more tests than any other country. Once the US doubles testing capacity again it will be on par with other large countries.
I would rather engage in discussion rather than publish monologues.

This is why I like HN/Twitter/etc.
> U.S. has swelled to more than 700,000 while Korea [...] have slowed to just over 10,000.

Comparing absolutes is not very useful so I thought I'd double check this. The difference is obviously less when normalized but the US is still an order of magnitude worse than SK:

USA:
700e3 / 328.2e6 * 100 = 0.213%

SK:
10e3 / 51.64e6 * 100 = 0.019%
Thank you for this comment. I was looking for anything here that might be relevant to me, and it looks like we both had hackintosh builds at the same time / version of OS X. In fact, it was the Snow Leopard->Lion upgrade which turned me off from the whole scene. Great to know things have evolved beyond that in a positive way.
Show HN: Teddy Bear Tracker iOS App
Two weeks ago when walking around my neighborhood I noticed a strange amount of teddy bears placed in the windows of homes. When I got home I searched the internet and found https://www.nytimes.com/2020/04/03/style/teddy-bear-scavenge... describing that this was being done to provide additional entertainment for people going on walks during these times of social distancing.

This past week I decided to repurpose some old code into an app that would allow me to keep track of the teddy bears I found while on my own walks. It's quite simple but I hope others can get some enjoyment out of it! :)

Here is the Apple App Store link: https://apps.apple.com/us/app/teddy-tracker/id1507523019
What about international flights? Are airports in SK still closed? I'm pretty sure they will have to limit traffic into and out of the country despite easing social distancing.

Otherwise, won't there be a new wave of infections when they let 'outsiders' back in from places where the virus is still running rampant?
It's good, just make sure to get a GPU vendor that Apple is currently maintaining a good relationship with.
Yeap. Look at the users' reaction to changes to Google News (must be ten years ago now), or to Google Maps. The GooN fiasco resulted in tens of thousands of complaints on their feedback page, and only one single "that was a good change" post that I ever saw--and that change was sarcasm (and tagged as such).

Did Google learn the lesson, and go back to the earlier UI? Of course not, because the Designers saw that the change was good. (Just in case anyone misses it, that last clause is sarcasm.)
I reviewed Burfog's claims.

While it's true that Chinese scientists were investigating SARS, the above assertion is not supported by the evidence provided.

My best guess of where the confusion came from was the insertion of a temporary mammalian plasmid into HeLa cells in order to produce bat ACE2 for study.

While this could potentially be viewed as adding functionality to human cells in order to make them susceptible to bat coronaviruses, the above assertion doesn't follow. (and unfortunately we have no ability to genome-edit humans)
There was the election of the National Assembly on April 15th, and it ended in an overwhelming victory for the party of the government. IMHO COVID-19 has shown how the current government is different to the last government that handled MERS - which was impeached (the percentage of supporters have greatly increased during the COVID-19 outbreak).
The coordinated mainstream media. Again, the narrative is if you think the US media is partisan you’re a Trump supporter.

The entire US media ecosystem is owned by only 6 companies. It used to be hip to distrust the media but now it makes you a Trump supporter or conspiracy theorist??

No. In 2020, students entirely have the upper hand. Colleges can no longer grow and shrink their classes according to the suitability of students. Their finances are dire.

Seven years ago I noticed I was getting really nasty allergies this time of year. I had never had allergies before. They got worse as I got older. My overall health did.

Two years ago I changed my diet and dramatically increased my exercise (keto and Brazilian Jiu-Jitsu). I had no colds or allergies anymore. Well, that’s not entirely true. I realized that I had had a few colds. They started the way my colds always did but lasted less than a day instead of nearly a week like they used to. And the allergies are completely gone.

I caught my first cold two months ago. That was right after burying my step father (the stress of his death coupled with flying to see him when he went into the hospital and hugging on a lot of family I hadn’t seen in years weakened my immune system I guess)

So... diet and exercise worked for me.
the unstated condition there is that the window for approximating linearity must be flexible for a given error envelope - smaller windows for higher rates of change of the curve. so while technically correct, it isn’t always practically useful.
Large bureaucracies do not have the agency to act in such a childish way.
That's neat, but it doesn't get around the initial setup process, which is what I thought (?) the GP was talking about. You need to know which kexts to use, what weird bootloader options to set, etc etc.

I've actually never been in the "never update a working Hackintosh" camp. For better or worse, I've always installed point releases, and I can't recall a single time when they've broken something. (Whole version upgrades are a different matter, but I'm cautious about those on real Macs too!)

How to thrive in an unknowable future (Written by Derek Sivers in 2016)
Hey all. Built this over the past couple of weeks as an alternative to more Zoom calls. It’s built with React and using Firebase for storage and compute and Twilio for video. Hope y’all enjoy.
China has been doing mandatory 14-day hotel quarantine for all foreign arrivals like this: https://twitter.com/nishantsharma87/status/12424610259510845...

However, the latest cluster in Heilongjiang involved an asymptomatic student returned from USA, completed 14 day quarantine, tested negative before and after, but still went on to infect her family and neighbors who infected more at the hospital. Total confirmed cases in this cluster is ~50 right now.

Most of the spread in this case happened because of negligence in the hospital thinking coronavirus is eradicated there so they didn’t take precautions. Coastal cities like Shanghai are taking good measures so there hasn’t been a problem despite it being where most international flights land and basically 100% back to work for over a month now. The biggest danger is people becoming tired of wearing masks and avoiding gatherings over time.
Not at all arguing that this is novel or innovative — rather my own take on the genre. I'd argue that some aspects of the system incentivize better behavior:

- It'll be a purchased app (not free), so the stakes of being banned are higher. Right now in beta, it is more open for sure.

- The 1:1 message sending doesn't give any feedback to bad actors, so attention-seeking behavior is more limited.

- I'm also hopeful to continue to design an experience that's calm and cheerful, and provides guidance about good behavior (in a way that's more in-your-face than most social media).

Of course, there will always be malicious people, and neither I nor this project are perfect. As I mentioned elsewhere in this post, I'd be quick to shut things down if it got out of hand.

Happy to discuss this more.
> On a recent PR, someone said "you should really find a way to do x". I had already spent half a day attempting to do so. This made me feel bad because it implied an assumption of thoughtlessness on my part and did little to help me out. But I wanted to be open to the feedback, so I spent more time trying to make it work. Finally, I brought this to the team and the consensus was that my approach was fine, that I hadn't been wrong in concluding there wasn't a good way to do x anyways.

Why didn't you push back? Software is a team sport. It's a collaborative effort where people bring their own ideas and approaches to the table.

When your co-worker gave you feedback in a code review, it's feedback. It's open for discussion. You could have brought it to the team earlier for more discussion or help making a decision.

Nothing you described has anything to do with the tech industry.
Well, first of all, there were no masks to wear. Not even enough to properly equip all medical personal. But yes, if people would wear masks whenever there is the risk that they are sick, be it Covid-19, the flu or just a cold, it would be beneficial.
