As Frank Herbert once wrote:

"My son displays a general garment and you claim it's cut to your fit. What a fascinating revelation."

It wasn't a personal attack. It's not my problem if you chose to apply it to yourself. But enough of your meta-discussion. You displayed an all too common misunderstanding about how (un)healthy older people are, so I challenged it. Here are some figures on co-morbidity factors for Covid-19.

* Cardiovascular disease 13.2%

* Diabetes 9.2%

* Chronic respiratory disease 8.0%

* Hypertension 8.4%

* Cancer 7.6%

(all from https://www.worldometers.info/coronavirus/coronavirus-age-se...)

So, how common are these issues in the 70+ crowd?

* 25-35% of US adults 65 or over have cardiovascular disease (range due to gender difference)

* 19-23% have diabetes

* 8-9% have asthma, 21-26% have bronchitis or emphysema (oddly the numbers don't cover COPD which I believe is around 15%)

* 55-57% have hypertension

* 21-26% have cancer at some point

(all from https://agingstats.gov/docs/LatestReport/Older-Americans-201...)

Given those numbers, what percentage of older people do you suppose have escaped all of those ills? Clearly less than half. So of course most of the elderly who have died from Covid-19 already had some other condition, because most of the elderly period have some other condition. Assuming the existence of vast numbers of elderly without such conditions for the sake of your argument is just not helpful.

Your turn. Bring some facts to the table instead of wild supposition and complaints.
Well, maybe. Additional costs with these approaches are often ignored. I wouldn't want to give up proof systems as a tool, but too many treat them as a zero cost panacea. A proof system or type checker is not an excuse to not give a fk about your craft, but I've seen it that way more frequently than I'd like to admit.

Personally and honestly, outside of already well understood or defined systems, I'd say that people should invest their time in understanding their business domain, before they dig deep into proofs and related techniques.
“Mass hysteria” sounds extreme and seems to exaggerate our joint response to date.

What I’ve observed from friends and news out of Seattle is general caution and a measured public response, which if successful can dramatically slow the rate of transmission.

I don't have any personal experience with these tools, but am also curious to hear from the HN community here.

Not at this time, but we're adding new features every week. If you're up for it, I'd love to learn more about your use case and how you're evaluating the different options on the market.
Here's an article[0] that mentions a containment product. Its a fire-resistant white polyester screen.

Some of the challenges include excess heat (HPS emit ~80% as heat) and moisture.

I haven't found anything that breaks down the costs. It seems the primary motivation is bylaw compliance.

I remember writing one of my first parsers was for a pdf and I had to employ a similar methodology where I had to rely on regex and "positionally-aware fixed-length" formatting rules. I would literally chunk specific groups by the number of spaces they contained lol. I had to do very little manual intervention but, damn it all, it worked :D .
No that's not the key difference, because you can just call `unwrap()` and forget about it, which is effectively the same footgun as other languages.

The key difference is that now the type system can tell you the truth. In other languages when you have a reference to a type T, null is considered a valid T but you cannot treat it as one or everything blows up. Meanwhile in rust when you have a reference to T, you don't have a secret (not)T that invisibly breaks everything.
I was at the Very Large Array (VLA) in New Mexico a couple years ago. It had a similar "turn off your phones and radios" sign and radio silence perimeter. They have tourists and a gift shop, so it's not as locked down as a military base.

"I have wondered how it is that my Mac Plus became a machine with almost no noticeable delays when I upgraded to 4mb ram"

I remember when I ran the original MacPaint (I assume it was in hand optimized assembler?) on a 16 MHz 68030 and it was amazing - everything seemed to simply be instantaneous. It put in perspective how when the 68000 came out, it was a "minicomputer on a chip" and the 68030 was conceived as a "mainframe on a chip".

I think the mistake is conflating all types of advertising. Direct response ads can work, no doubt! But branding ads and things more subtle, are trying to influence behavior that has many inputs.
More than half of our customers have asked to be able to skip our cloud and go directly to their database. We’re working on this right now. It’s scheduled to be released this week, so keep an eye open.

In the meantime, if you have any questions, feel free to send me an email at siftrics@siftrics.com. I’d love to hop on the phone or do a Zoom meeting or a Google Hangouts.
Hey, there! First time posting to HN. A little info about what and why is this package, and the future of it, in hopes that it catches some attention and gets to help other php developers out there.

I wanted to calculate several statistics about a project I was working on, ideally wanted to write and perform them the same way you write and perform tests with PHPUnit, and I was baffled to discover there wasn't already any existing library to do that, not libraries to do it like PHPUnit, but any library at all.

I created PHPMetro to allow me to just write cases extending from a base case, add data on setUp and automatically perform test methods from console. And I think my library does a pretty good job at it's task.

Despite being an statistical analysis tool it does not provide any methods to perform statistical calculations, there are already very good libraries that do that.

Instead PHPMetro lets you create stacked analysis cases with contained samples that are dinamically generated, and perform and obtain a result from as many tests as you want.

I'm currently working on improving the current run performance, i.e reduce time and memory consumption. Since it's main ability consists in generating sampled data makes sense that it's good at doing that at large scale (samples in the hundreds of thousands in size).

Of course, feel free and welcome to join and contribute to this package if you spot anything that could be fixed and/or improved, I'd also love to receive some feedback about it of people who find it useful/interesting/etc.

Actually Moviephone predated widespread cell phone usage. It was just seen as a novel AND useful way of getting movie times.

There was no Google, you had to look through the paper and find ads for individual theaters to know where and when movies were screening.

Techniques for modeling pandemic spread in large offices
Not to sound like a broken record (I and others have said this or similar on these kinds of threads) but... I, personally, have become convinced that looking for signals this way is actually pointless.

The argument is basically this:

1. Within 1000 years (and maybe a lot less) we will have the engineering capability to build space habitats, powered by solar power. This last part is important because this thought experiment isn't gated on commercial viability of nuclear fusion power, which I'm not yet convinced is possible.

2. These space habitats are far more efficient at creating living area than planets. I forget the exact numbers but something like 1% of the mass of Mercury is enough to create enough living area for something like 10^16 to 10^18 people.

3. Space habitats are more convenient and cheaper to move between than leaving or even entering a gravity well like Earth's.

4. Roughly one billionth of the Sun's energy hits the Earth.

5. Once you have the ability to create one of these things, each becomes progressively easier.

This, of course, is the classic Dyson Swarm. Originally this was called a Dyson Sphere but this has led some to think it's a solid shell around a star. That was never the intent. Even if it was, no known or currently theorized material could support this.

Dyson Swarms are not subtle. Even a partial Dyson Swarm should be detectable as a large IR source compared to how much visible light is produced. This is because the only way for something in space to cool down is to radiate that heat away and physics determines the wavelength of that based on the temperature of the object.

Standard objection: what if you can recycle that heat? Well, you can't do that perfectly (as this would violate Thermodynamics) and even if you reduce IR emissions by 90%, you've simply reduced the IR emissions by one order of magnitude. For comparison, the Sun produces roughly 4x10^26 Watts of power.

So if you accept the above premises the gap between stabbing each other with swords and having this technology, at least for us, is 1000-2000 years, a cosmic blink of an eye to produce signals without the above IR signature. Those are long odds.

Personally I subscribe to the view that technological life is, at least within a billion light years of us, is likely quite rare.

The above is a very superficial summary of a topic that Isaac Arthur's channel goes into great depth about. I guarantee you any objection you have has at least one video that goes into that in great depth.

Your #3 is not borne out by evidence or studies. Respirators, surgical masks, and pediatric masks have all modeled and/or shown to provide a significant degree of protection.

A related questions to ask oneself:

- who most needs to be healthy, you or medical providers?

- assuming we agree medical providers are in greater need of remaining healthy, does buying a mask from Ace Hardware or Home Depot take it out of the hands of a medical provider?

- will masks being out of stock at Ace Hardware affect a supply chain decision that would have otherwise gone to the hospital? if so, who is doing that wrong and why not intervene there?

- what about the principle where airlines tell you to put on your oxygen mask before your child's, and the notion that some % of Americans will find themselves as medical care providers to a household?

Having enough masks for the second scenario is relevant if you have 'at risk' household members.

On #4, some research suggests 9 days at comfortable room temperatures, 30C for instance.
When we launched https://VisualSitemaps.com, we decided to use D3 since it really showed the site-mapping DataViz[1] really well and even allowed for real-time manipulation ( try drag n droppin the nodes in the demo below )

However, it does have its performance degradation once you go beyond 3000 nodes of data. So we are now in the process of rebuilding our mapper in Canvas+WebGL via Pixi.js.

HTML has all the same problems and degrades over time. A PDF from 20 years ago will at least be readable by a human; a HTML page does not even guarantee that much.

You're right that most of the relevant semantics would fit into Markdown. So store the markdown! There are problems with PDF but HTML is the worst of all worlds.
What aspect(s) of my post suggest that I object to scientific process? (I do not believe myself to hold the opinion you're attributing to me.)
Buy an iPad Pro with the Apple pencil. Digitizing your handwriting is game changing. Email me if you want me to send you my Notability and Goodnotes template with some examples from the last 4 years of note taking.
I do not remember which of the two it was, but 'poppler' or 'pdfbox' (they may use the same backend) created great HTML output, with absolute positions. They also have an XML mode, which is easily transformed.

Of course, there is absolutely no semantics, just display.
It's not really like this in Europe, not sure what made you think all medical care was free ?
There are many cases where you are left on the side of the road in Europe too.
It's certainly better than in the US, but far from free for everyone.

So someone internally stole them at dropbox? Did you have it shared with the public?
An integration manager is just a webapp which spins up and adds bots/bridges/widgets (collectively, 'integrations') for a given room - like a small appstore from which you can add extensions into a room. The available bots/bridges/widgets depend on the integration manager; i guess you could call the ones it chooses to provide "official" ones.
Not really. When programming was done by real engineers (rather than "coders", "developers", or horribly misnamed "software engineers") - with proper engineering discipline which involved deliberate design and documentation rather than "agile" hacking, it was more reliable. By far.

My personal recent experience of actually doing software the old-fashioned way involved writing correctness critical high-performance code for a major data warehouse vendor, which mostly stayed with zero known bugs in production - greatly contributing to the vendor's reputation as reliable and dependable place to keep your data in.

And how do I know what the old-fashioned way to write code is? Well, I've been writing code professionally for nearly 40 years.

Ask HN: Git Hooks, who uses them and for what purpose?
https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks

Decided to learn more about them the other day as they seem interesting. In a quick search here for past discussions it seems this feature is used in a variety of ways and more-so than I had anticipated. For those of you that use git hooks, how do you implement/enforce their usage for projects, and what are you doing with them?
I believe we make our own "luck", and I think the above quote is elegant!

WRT finding interesting ideas...

We used to talk about "increasing your surface area of luck" by meeting more people, getting exposed to more ideas/ opportunities etc.

If "Innovation happens at the intersection", then the more you come into contact with, the more your chances of finding an interesting (non-obvious) intersection between problem and solution, or two entirely different solution domains.

WRT executin:

I criticised the "something I know/get is good, something I haven't used seems inaccessible" comparison only.
I'm comfortable with Apple implementing biometric authentication, for convenience, because I trust them to let me retain control over my data. FaceID data doesn't leave the secure enclave.

The For Convenience part is essential: FaceID is a liability to security. It improves usability of the security, which means people will actually use it, but it does not improve the security itself.

It does mean that you can use a longer passcode (encryption key) because you only need to enter it on reboot and after enough negatives. (You can also squeeze both top buttons to disable FaceID)
Server meaning the one your client connects to.

The resource requirements of joining a busy room with lots of members is mainly RAM, and it spikes at join and initial sync, but does then occupy room in memory and the DB to maintain state for all the activity in that room. For something like ##rust you should expect to see an initial spike of a few hundred MB of RAM which then dies down again. This can be optimised massively, but we haven't got to it in Synapse yet. (Dendrite is looking way better though).
Someone could find out your password and use your card. Doubt someone can perfectly steal and use your vein pattern and gait.

Remember, biometrics are not supposed to be a replacement for passwords, they are supposed to be an extra auth factor.
Would you retain better rapport with the investors if you returned money and started something fresh rather than persisted when you were lacking conviction?
Can you not imagine that there are consumer benefits to a non-replaceable battery? Benefits that consumers may be choosing?
You get what you pay for. $300 is 20 minutes of a good lawyer’s time. The economics don’t work.
Maybe? I would actively resist any attempt and/or never use a thing that required my biometrics to a private party without good reason. Once somebody has them, you're screwed. For life. You can't change that about yourself. Why are we incentivizing people to spoof / fake them? Why are we encouraging people to use these things? Please no. No more biometrics. I will not do it.
I'm trying to have a genuine discussion here with you, but that requires two-way communication.

I've laid out what I think to be the issue between our perspectives. If you disagree, that's more than fine, but you've got to give me more than a "you're wrong" if you want to have a meaningful conversation.
This was originally going to be a reply to Fruffy's comment.

I don't see mass hysteria, but I do see growing concern.

The last several decades of child-rearing in the US have been marked by an increased focus upon stress rduction, conflict mitigation, and obstacle-clearing for the purposes of opening up a larger swath of opportunities for our children in their futures.

Especially among the upper and middle-classes, I believe that this has resulted in a larger portion of the population lacking the fundamental coping mechanisms to respond rationally and proportionally to perceived threats.

Combined with a lack of actual experience dealing with pandemics in our cultural memory, lower social capital in our immediate communities preventing stronger bonds of mutual reassurance/support, and our ability to communicate our concerns with a broad likeminded audience over the internet, and I don't wonder that an unreasonably high number of young individuals panicking over the COVID outbreak.

I don't know that this is the case in Europe, as it is outside my direct experience. But Europeans seem to have a greater sense of institutional trust than we do here stateside.

We seem to be in a constant state of cultural hyperventilation right now. Of all the wolves we've worried about wandering the earth, COVID's the one that's actually coming for us, irrespective of ethnicity, gender, or creed, and it's also the one we lack the tools to effectively combat at scale.

Even though the article raises a number of reasons why the outbreak may not be as bad as we fear, if someone's truly concerned that they're in danger of passing from it, reach out to them and ask how you can help.

Especially among the lower-classes, self-quarantine isn't a realistic option, and constructing a network of mutual support for the event that it does become as bad as our most panicked commentators say it might be is a good way to keep everyone's emotional and physical struggles down while we weather the storm, if and when it comes.
That was one step (in december). Not the only step, which the WHO mentioned specifically in their latest report. The locking down of Wuhan was instrumental in limiting the outbreak. I am, almost universally, critical of China's government and evolved social systems. This is an exception. They took pragmatic steps that were effective.

It's not my job to decide what counts as a "problem", but if the boss wants me to handle the CTO drunkenly leaving her phone in a taxi as an "emergency" to react to at 0200 then as described above I want the resources to handle that in advance when I predict it'll obviously keep happening. If my boss doesn't want to divert people or money on preventing such bullshit problems, then I don't want to get woken when they happen.

At huge scale there just will be incidents every day, if you're SRE for Google then every day is a bunch of problems - but at that scale those are routine incidents and you can afford the follow-the-sun team (actually I think Google SRE found it was better not to have true follow-the-sun but just two groups) to handle them, leaving only still rare "San Francisco just fell into the Bay" level incidents to actually wake people up.
If you're already rich (as Justin is) and realize how big an upside can be, why not flush the toilet and start over? For a guy like Justin, time is the most precious commodity because money is meaningless.

It doesn't increase the number of macOS kernels, or decrease the number of Linux servers (including virtualized ones, which seems fair), so I doubt it tips the balance.

All I'm saying is that, because of servers, there are more GCC'ed Linux kernels than there are Clang'ed macOS kernels, and this will probably remain true indefinitely.

If AWS starts Clangin' on their Linux kernels, then maybe not. The trend toward Clang is pretty clear at this point; could happen.
Every piece of software defines an input space of all possible inputs for that software. This space is staggeringly, exponentially enormous. However, the space of inputs that are actually given to the software are generally an exponentially small subset of the possible inputs. Making this often very stereotypical and "friendly" space of inputs do mostly sensible things is at least polynomially, if not exponentially, simpler than making the software be entirely correct.

It is both true that software is a streaming pile of bugs, where the vast, vast majority of responses to possible inputs is somehow wrong, yet the vast, vast majority of inputs actually processed by the software are mostly correct (not entirely, but mostly) because they are in the generally polynomial subsets of the exponentially complicated space that the developers made correct... ish.
