> I wonder if any organizations would benefit from the effort to maintain an officially-recognized triage list of "we have to let these remediations die" issues, instead of a backlog. Once issues make it into a backlog and stay there for longer than T time (usually about a year), I've very rarely seen the issue make it out of the backlog into a sprint again, even years later.

Another option is to treat backlog as a graveyard for issues. They might rise from the dead, but most of them will not. Still, it is useful to have them. When someone comes with a "novel" idea they can use the old ticket with all the existing discussion pro & cons instead of starting the same conversation over and over again. Surprisingly lots of things only seem like a good idea, but when discussed they turn out to be WONTFIX issues.
Staying home and puttering around at a CC can be a better choice than spending time at a big school if you are not ready for it. Especially if you are paying private or non-resident tuition.

My daughter's freshmen dorm roommate should have stayed home. She spent much of her time pining for her boyfriend at home, rarely doing anything outside of class. She got pregnant by the boyfriend and now is dropped out. Kind of a bummer really, she is an under-represented minority who had a full-ride for Chemical Engineering.
You're going to lose that gained time as soon as your "build" includes running tests. And you'll need more tests because in dynamic langueses generally nothing works until you check it with a test.

Mixing lanuages is a waste. It makes everything harder operationally, technically and business wise.

The solution to long builds is projects structure that supports caching and parallelism. No one ever changes more than couple thousands lines even in a multi million line project, so why would everything had to get rebuilt?

I've seen ci pipelines building millions of lines in under a minute, no sweat.
I wonder if this same principle could be used to store air for scuba tanks. It would be an improvement over existing compressed air tanks if the tank could be made smaller and lighter.
Thank you for this comment. HN just likes to put Google's contributions down.
Amazing! I made a shitty version[0] of this last year. I guess great minds think alike, but greater minds execute better!

The only time your keys are uploaded, is when you are infected. The assumption is that if you are infectious certain privacy needs to forgo to protect others.

In fact this is over simplification. The only key that will be uploaded is partial of the daily tracing key (called Diagnosis Key in the specification).

Most importantly, there's no location or timestamp involved or needed. Once this Diagnosis Key is uploaded, every client (anyone who wants to know if they are potentially infected) will periodically download the batch and see if your phone has seen any of the Rolling Proximity Identifiers, and when.
Australia to force technology giants Facebook and Google to pay for news content
How can spike say on their front page "The Spike S-512 is the only supersonic jet in development that will fly at twice the speed of other jets without creating a loud sonic boom." Boom is also aiming for 2x existing jets without sonic booms. That's wrong, misleading, is there some narrow explanation for how that could be accurate?
Well, unless you have a vaccine, the virus does all of the work for you. Also, you can't really leave a country now anyway, and even if you could, the virus would be at the destination.

The herd immunity is not really something that you do but more of an unavoidable side effect. I'm not sure that we have much of a choice now that we are well beyond the point of containment.
The other thing this article made me think of: the stone tools get stored in a cave and forgotten (the small band of users get wiped out for some other reason), then another band finds the cave (because of a rainstorm) and the tools and the broken bones nearby. They figure it out and “own” the cave and the tools for a few years/generations until history repeats. Over the 200,000 year use of the cave, maybe it sat dormant for 1-5,000 years at a time. Imagine finding a cave in a mostly empty land, and finding useful artifacts inside.
This really sinks the value proposition or a mac tower. You are getting comparable performance for 1/4 the price...
I had the old mac pro, and I did love the quality of the build and ease of drive installation.. But still.

"Single-core score: 1,121
Multi-core score: 11,769
The scores for my Hackintosh with an AMD Ryzen 9 3900X 3.8 GHz are:

Single-core score: 1,259
Multi-core score: 10,515"

I switched to linux for the most part at this point (My work machine is still a 2015 MacBook though..) I had a hacintosh tower 8 year ago but I was always nervous about upgrading it.
While I agree on the inequality, the US does have the highest charitable donations per capita of all countries worldwide by quite a margin [1], which seems to be a good measure of generosity. Although the counterpoint to this might be that said charity is only necessary because of the effects of a kind of systemic selfishness? (I don't know this subject matter very well; more informed perspectives very welcome)

> Empirically, people with kids almost never achieve outlier levels of success

That's ridiculous. Do you have any way of backing that claim up? If you're using the word "empirically", you should have.
What you describe is how iOS was first released. Anyone who wanted to build an app would use progressive web apps. Every native app was controlled by Apple only. This was loathed by developers and corrected in a later release.

Given the steady recurring posts here on HN and elsewhere about hoping that Apple will open up to third-party app selections for email/browser/etc. someday, suggesting that Apple control the only Covid app on their platform is contradictory to that goal.
Facebook Is Launching a Dedicated Gaming App to Take on Twitch, YouTube
In the system proposed, not really.

To use TCP instead of UDP there are two big problems:

1) the sensor device would need to keep unacknowledged data in memory, but it may not have enough memory for that

2) if they're running at line rate (max bandwidth in this case) in UDP, there's no bandwidth left to retransmit data

All of the buffer manipulation is going to be more CPU intensive on both sides as well, and you'd run into congestion control limiting the data rate in the early part of the capture as well.

For a system like this, while UDP doesn't guarantee reliability, careful network setup (either sensor direct to recorder, or on a dedicated network with sufficient capacity and no outside traffic) in combination with careful software setup allows for a very low probability of lost packets dispite no ability to retransmit.
Because "old media companies" are Rupert Murdoch, who does in real life what George Soros is accused of doing by media outlets controlled by... Rupert Murdoch.
This looks like an admittedly clever hack to avoid the fantastically expensive APM and still get some useful exception logging. I really wanted to use Datadog’s APM but $31 per host was too much. The downsides to logging to the event stream like Errorship is that you can’t associate exceptions with requests and aggregation is limited to tags. I think event tags have a low-ish cardinality limit similar to metrics.
> Thank you for the effort, but I don't believe there is much more to say on the subject.

You were wrong about what you claimed. That certainly needed to be acknowledged given your responses here.

So basically rate 1/2 FEC.
This feels like it could be managed in firmware. It's been well established that many modern SSDs will use a large volume of the NAND in a SLC style mode for performance reasons, and only switch to MLC/TLC/QLC mode as the available space to do so runs down. I would be curious what effect that has on reliability-- if an individual QLC flash cell goes bad, is it still typically usable if you're using psuedo-SLC coding?

To go a bit further, I'm amazed you don't see a drive manufacturer offering an enterprise-client "firmware builder" tool, or at least as a build-to-order service if you're a big enough client. I could see customers that wanted to respec their 1TB drives as, say, 750GB to ensure an abundance of over-capacity for reallocation later, or the YOLO "I'm gonna run the cheapest drives in RAID0" crowd slashing overprovisioning and getting 1050Gb out of the same unit. If you dialed down the capacity low enough, the drive could presumably stay in "use SLC mode only" mode for its entire duration.

One screen, two GPUs. For the screen I've got an LG 38GL950G, and the GPUs are a Radeon WX5100 (macOS) and RTX 2080 Ti (Windows). I run the Linux host (Ubuntu) headless.

I have the macOS side connected via HDMI and Windows via DisplayPort. Then I switch inputs when through the monitor's OSD for changing the OS (I think there's a way to do this through DDC/CI commands depending on the monitor, in which case you'd be able to write a script to do this, haven't looked into that yet). I have a USB switch for moving all device connections to the OS of my choice.

Also the board I have, an X299 Designare, has several USB controllers on their own IOMMU group so you can pass through each to their own VM.
I like this. Big tech, time to pay some taxes to countries.. All of these big tax avoiding companies.
And where are you getting this information from? Just anecdotes of people you think are smart, went to community college, and got rejected?
Is there a site or disscusion area that lets you know the likelihood of any proposed bill or law having a chance and what chance at passing? The $2K/mo seems like it would never get far, for example.

Honestly interested to know: Is there any added value for a Python developer in learning and using Scala? I love Python, especially because of its ecosystem, its widespreadedness, and of course because of Pandas, Numpy, Matplotlib. But I miss functional constructs from Mathematica or Scheme. Scala seems to be much more systematic and profound, but again: For everyday usage, is it overkill?
I think you overestimate the market pull for the product legacy media companies produce. Removing legacy news from Facebook and Google would certainly hasten the death of legacy news and have no effect on tech companies, who's users would just replace legacy news with reddit posts, blog spam, etc.

In order to fix regulatory capture at the structural level you have to fix campaign finance in the US. It's the only way.
Yeah, they got caught in a bit of hyperbole there!

Yet, if you take the 2017 budget [1] for example, nearly half of the net contributions (excluding the UK) were paid by Germany.

Google seemed comfortable losing any number of employees over Dragonfly, and firing organizers against it and other issues. It seemed like Congressional pressure, not employee activism, was what actually made the decision for them.

Obviously Maven wasn't shut down due to government pressure, but I feel like you drastically exaggerate how concerned Google is about valuing its employees.
What always seems to happen with UBI studies is the proponents point to results that say "the people we gave free money to are happier" but never try to quantify whether that money would have done more good used in a different way.

I've been using vscode's remote ssh capabilities which works really well. Allows me to use my main PC to edit files on all of the shared devices as long as they have ssh enabled.
SetApp has business and a personal pricing? I don’t know any difference beyond number of devices. And likely business has more admin control etc.

Otherwise Setapp is Netflix for Mac apps. A pretty limited amount. But no ads and the selection is pretty good.
While this is quite interesting and points to a mechanism long -proposed in theoretical physics, the null-hypothesis is only just barely ourside the 3-sigma range. In particle physics, 3-sigma results come and go all the time. They should be seen as nothing more than an indicator that more research and experimentation should be done in this area (as is already underway with new neutrino detectors in the works in both Japan and South Dakota).
The main reason for the difference is that there's just a lot less code being executed. The XDP code runs very early on, basically immediately after the nic receives the packet.
The XDP hook is placed in the NIC driver just after the interrupt processing and before any memory allocation needed by the network stack itself.
It is not being sent up the Kernel. So all this happens before an SKB (the most fundamental data structure in the Linux networking code) is allocated. Practically this means this is executed before things like tc and iptables. Less code, much faster.
I guess what makes this situation different is what their doing is borderline criminal and it's probably going to get people killed.
They're generally a good guide to the conventional wisdom from a center-right perspective, but they seldom yield insights.
Huh, from the hangout and hack stuff all day at the maker space perspective this is flipped completely on its head. I have plenty of time to design things and operate machines, and even the cost of the machines (bits included) is shared to the point that it's almost free as an individual. It's waiting on those gosh darn materials budgets to appear that holds up all my projects.
I'm about as "red as they get" and there's something really grating about US citizens talking about "UBI", and pointing to a variety of social policies in various European countries.

These policies are hard-fought and need to be well balanced to be effective in the long term. You can't just implement them without thinking about repercussions and side-effects.

I'd say, if you're a US citizen, forget about "UBI" as a simple answer to the various social wrongs within your country, and focus on your healthcare; that's where various European models could be used as a partial model, and it's a very good and achievable first step towards a fairer and healthier society.
Vendor lock-in is the primary way in which these companies make money
99.99% for two tries would be a 1% drop chance which I'd say is pretty lenient - we average better than that on our sites running off 4G (jitter is horrible though and that will kill any real-time protocols without huge delays added).

Generally you'd just implement a more generic FEC algorithm though unless you had 2 separate paths you wanted to try (e.g. race a cable modem and 4G with every packet and if one side drops it hope the other side still finishes the race) as there are FEC options that allow non integer redundancy levels and can reduce header overhead compared to sending multiple copies of small packets.
Absolutely, the efficacy of contact tracing has been known for a long time.

That being said, we’ve also been doing interview based contact tracing for a long time. The current IT systems for doing contact tracing leave a lot to be desired (I did a trade study a couple months ago), but public health agencies have procedures for doing contact tracing without invading privacy nearly as much as the proposed platform.

Preemptively using smartphone interactions to capture information world definitely be cheaper than the current manual processes but I want to know how much it improves efficacy before nationwide/global deployment of such an invasive technology.

Until then, hire contact tracer’s. There are a lot of unemployed people.
scala blows, use kotlin
Prime example: I opened up cnn.com which some people consider to be a news web site. The main headline is "Experts say grocery stores may need to keep customers out" (https://www.cnn.com/2020/04/19/business/grocery-stores-coron...). The real story is that grocery store workers are dying but a title based on that isn't clickbaity enough. It has to make you think the article actually affects you so you click it. I probably wouldn't have clicked the link if it was about grocery store workers getting covid-19.

And of course their "experts" are just random people who said some things. And they mention that even if they do keep customers out they while still have pickup and possibly delivery. So who cares about that part of the story then? Apparently it's not going to affect me.

The media has done nothing to prevent panic buying and everything to encourage it with these click bait headlines. There is no reason stores should be running out of anything but PPE and other things where demand naturally shot up because covid-19 like PPE and disinfectant. Demand for toilet paper only went up because of the media (and government). The other thing the media has been doing is shaming people but I'm not going to go there.
Odds are, at least one of the links between the source and destination will be shared. If so, sending two packets is an expensive attempt at reliability; it will cut the bandwidth in half. Further, one data packet will arrive with a highish success rate.
There's also a concern that the filters in an ECMO machine damage or eliminate the antibodies that are trying to fight the virus.

So putting someone on an oxygenator might condemn the patient to stay on one until the virus kills them.
AB testing yes, this specific test maybe which is why the GP was asking about the assay.

The current AB tests were found to be insufficient.
Pretty frightening that you can’t see the obvious bias.

They could and should have named the “Iranian teen” in the headline instead of glorifying Magnus as some unbeatable chess god. Not to mention that in the actual article itself the hero image is of Magnus holding a trophy. For an article about how he lost.

Get with it.
Going from "People being critical of your wife and not you for the same actions is just conversation!" to trying to guilt a guy for...pointing out that his wife experiences sexism...is pretty strange.

> It seems like a lot of people get married and have kids just because it's the thing people do. Which I guess you can't really fault them for, but it is the root of a lot of society's problems as you say.

My case would support your supposition because I was distressingly incompetent in my early 20s. I wasn't a prize at 28 (my first born) either but at least I was at a point where I could form better expectations for myself.

Past that, I find most young people today to be measurably more balanced & competent human beings than my generation was. I have strong confidence in their abilities to guide little people.

To be clear tho, even in my generation I was a terrible outlier.
Active Learning with PyTorch Using Scale
This is an interesting concept that I hadn't thought about before. Seems similar to the rent vs buy argument for a house- spending more money in total, but spreading out the payment, can be more profitable in times where the economy is good. Of course, this assumes that the country will continue its growth at a rate that offsets the increased spending.

Haha, I usually only remember to use it when sites have a terrible design and not to get around the cookie crap. Thanks for the reminder.
A curve with the properties you describe is not smooth, by definition, since it is not differentiable.

> At whatever scale you look at the curve the derivative is always wrong: you zoom in on the sine, at the peak it's got a cosine, so the d/dx is -1; but zoom in and the cosine has a sine at the crossing point, so the d/dx is 0; but zoom in and ...

This is pretty much the definition of something not being differentiable. "Differentiable" means that the approximations to the derivative (i.e., difference quotients) converge to some fixed value as the scale they're measured at approaches the infinitely small.

You might be interested in the Weierstrass function, which seems to be the sort of thing you're getting at with your idea: https://en.wikipedia.org/wiki/Weierstrass_function . Continuous everywhere, but differentiable nowhere.

Edit: the specific function you wrote down is not differentiable (at least not everywhere). For example, at x=0, its derivative, if it had one, should be cos(0) + cos (a * 0) + cos (a^2 * 0) + ... , but that series clearly diverges.
> A quick scan of the linked project suggests no such healthcare provider code is required.

That's why this is a sample app and not the actual application that public health authorities will be using.

See below:

"A representative from Apple and Google's joint contact-tracing project said that their system similarly envisions that patients can't declare themselves infected without the help of a health care professional, who would likely confirm with a QR code." [1]

Like some others have said. Getting it via Setapp is great. The prices aren’t far from one another and Setapp offers other apps. Setapp has the device limitation too, but since it’s basically the same price, add a few more seats if needed.

Setapp lets you use apps on as many devices as you want. But like streaming services these days, you can only have apps through Setapp actively running based on the seats you have. Though if you have say 2-3 seats for Setapp. And launch Setapp and some apps on a 4th comp. whichever comp has to get off Setapp to give space, you can usually keep apps open. Just can’t re-open them until a seat space is available again. M

Tech for good during Covid-19: Children’s book, phone booths, and aperitifs
The system is intended to be annonymous and can't have any user registration or authentication.

How can you validate when someone report they are infectious, the Diagnostic Key is indeed from a legit iOS device? If you can't validate it, this can be easily abused (attacker generate a huge list of Diagnosis Keys and upload, claiming to be infected, and causing a wave of public panic)

My understanding is that there must be some internal/proprietary API from Apple that they are using to validate this, and there's no other vendor except Apple to develop such an API to mitigate the abuse risk.
Forget which country it is, but there's already another that's pushing this on Google (for their News aggregator).
