That doesn't appear to be entirely correct - from my research, it appears to actually have been about 12 deaths (the last on March 28th from https://www.mhlw.go.jp/stf/newpage_10599.html) but there appear to be multiple sources on this.

Regardless, I'll admit that I was wrong - there are still people dying. Regardless, we'd have to get about 3-4x the number of deaths we've had so far to reach 5% - and from the sources I can find most of those remaining cases are non-critical (though there could be even a doubling).

But what’s the theory then? If there was a widespread milder version of covid going around in places long before the deadly one took hold, then the newer deadlier strain would still have to be transmitted into each region separately. I don’t think it’s feasible that the mild strain spread globally and then flipped a switch and turned much deadlier all around the globe.
If you write a project, you probably won't change the database. But you may add new data layer services such as a cache backend, a search engine with, a secret server, a session store, a permission micro service, etc. They will all interact with permissions and change where you source the data from.

Then there is the case where you don't write a project, but a lib. Or the case where you extract such a lib from a project. In that case, you limit the use case of your lib to your database. Because if you don't change database during your project life time, the users of your lib may start a new project with a different database.

This is why Django ORM allowed such a vibrant ecosystem: not because it allows changing the data base of one project (although it's nice to have and I used it several times), but also because it allow so called "django pluggable apps" to be database independant.

> I actually thought viruses lived forever, but I was wrong. The paper linked in this article says 1 day on cardboard, 3 days on plastic.

I think it's more complicated than that. There are viruses that are enveloped in a membrane, and ones that are not. Unenveloped viruses can survive much longer on surfaces. IIRC, Covid-19 is an enveloped virus.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4462923/:

> Non-enveloped viruses, such as coxsackieviruses, rotavirus, or poliovirus, can survive for extended periods on surfaces (9, 10), while enveloped viruses, including H1N1 and human coronaviruses, remain infectious on surfaces after several days (6).

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1564025/:

> Most viruses from the respiratory tract, such as corona, coxsackie, influenza, SARS or rhino virus, can persist on surfaces for a few days. Viruses from the gastrointestinal tract, such as astrovirus, HAV, polio- or rota virus, persist for approximately 2 months. Blood-borne viruses, such as HBV or HIV, can persist for more than one week. Herpes viruses, such as CMV or HSV type 1 and 2, have been shown to persist from only a few hours up to 7 days.
> Force-induced gene up-regulation does not follow the weak power law but depends on H3K9 demethylation

I'm sure it's common knowledge to people inside the field, but "The weak power law" is quite vague for non-experts.

From the article I got this:

> In this study, we reveal that high force frequency (>50 Hz) does not induce rapid transcription, although the chromatin is being stretched to sufficient extents to allow for transcription. Over the last two decades, studies on the rheological responses of living cells demonstrate that living cells exhibit a gradual stiffening response to increasing force frequencies [i.e., the weak power law (12, 27)].

Ok, that doesn't really clarify that much for me. Is it the (weak power) law or the weak (power law), for example? I mean we're talking about exerting force, both kind of could make sense.

Any experts willing to explain a bit?

Agree with you on this. For text data, there was a paper called "UDA"(https://arxiv.org/abs/1904.12848) that did some work on this direction.

They augmented text by using backtranslation. Basic idea is you take text in English, translate that to some other language say French and then translate back the French text to English. Usually, you get back an English sentence that is different that the original English sentence but has the same meaning.
Another approach they use to augment is to randomly replace stopword/low tf-idf(intuitively say very frequent words like a, an, the) with random words.

You will find implementation of UDA on GitHub and try that out.

I am learning these existing image semi-supervised technique right now and the plan is to do research on how we can transfer those ideas to text data. Let's see how it goes.
I believe the database described is Greenplum[0], which was a fork of PostgreSQL at 8.3, I think. It handles truly enormous datasets.

There's been an ongoing multi-year project to merge Greenplum up to the mainline so that it's no longer a hard fork.

Disclosure: I work for VMware, which sponsors development and sells commercial offerings of Greenplum.

It is just as likely that health experts are overestimating how long Americans can stop the economy. This happened so fast that most people really could not even wrap their head around the changes. I would love for us to keep working from home, reduce travel, and get this thing under control, but at least up until now, I have a salary, and am not being adversely impacted.

The number of Americans being adversely impacted is in excess of 10 million today, likely closer to 20 million, and pretty soon almost everyone is going to share some level of pain.

This is going to be a very tumultuous 2 years.

IMHO, the direct competitor of Server.app in the "SMB office server" use-case is actually a Synology NAS appliance. Synology's set of first-party OS packages has 1:1 feature parity (and then some) with every function Server.app either has, or used to have.

And that's the key-word here: appliance. A NAS is a standalone box that receives automatic updates, is 100% remote-management enabled by default, can be easily reset to factory settings, and can't be messed up by employees who think it'd be neat to run local native apps on it, "since it's a computer just sitting there."

Plus, since a NAS isn't going to be doing any desktop-OS things, the software for it can be slimmed down enough to run on lower-specced hardware, making the appliance itself much cheaper than the sort of machine required to run Server.app smoothly.

No SMB office-manager who needs this kind of functionality these days would buy a Mac or PC, to set up server software on it and leave it sitting there headless in the office. They'd buy a NAS.

And, IMHO, that's why Apple haven't kept Server.app up to date. There's just no demand for it any more. Not because of the cloud (which is mostly a complementary use-case) but rather because this software-solution vertical has now evolved into a turn-key hardware-appliance solution vertical. And it's one with slim-enough profit margins, that Apple doesn't want to compete.
The options are very limited but the default options are an O-1 petition or a green card application (where there is no backlog in the category such that you can file an I-485 and work authorization applications immediately).
It's not just people reading tech news.

People in Tennessee watching regular news on free over the air antenna (non-cable news) -> https://www.wsmv.com/news/security-experts-warn-about-zoom-h...

any anyone who is within earshot of such 'non-tech news' is hearing how unsecure zoom is.

However people who don't even own computers are seeing this debacle.

So, anyone I've advised to use zoom for privacy and security, citing the encryption and use by US gov - is going to have to wonder - how do these things happen on a secure, private, encrypted system - must not be what it was purported to be by that guy Steve. Then they are going to wonder what kind of damage could be done with the info that was 'securely' shared with the service.

> - Postgres' version of upsert allowed any command to be run without checking the permissions. So the vaunted "software engineering" behind Postgres is not that solid.

That never was the case (see evidence in initial commit [1]). Are you talking about CVE-2017-15099? Obviously annoying that we had that bug, but thats very far from what you claim.

Since you write "I'd appreciate if you're itching to write a hasty response that you actually check your facts first." you actually follow up your own advice?

> - Postgres' COPY FROM and COPY TO have been used to compromise the database by copying ssh keys to the server, amongst other things.

If, and only if, the user is a superuser. It's possible to do the same in just about any other client/server rdbms.

> Some constructive advice to the Postgres developers is to take a week and add grant commands to limit COPY FROM and COPY TO

You mean, like it has been the case for ~19 years? https://www.postgresql.org/docs/7.1/sql-copy.html "COPY naming a file is only allowed to database superusers, since it allows writing on any file that the backend has privileges to write on.".

> - Currently Postgres is subject to around a dozen metasploit vulnerabilities that any script-kiddy can execute.

That does not actually seem to be the case (what a surprise). And the modules that do exist are one for a (serious!) vulnerability from 2013, and others that aren't vulnerabilities because they require superuser rights.

Molecular Biologist Says Covid-VM 19 Could Have Leaked from Wuhan Biolab
For me, this is par for the course. When I propose in measuring things like Reiki, or other forms of occult energy (notedly not: em, weak, strong, gravity), I get told that there's no way to measure directly. When I propose a way to test and potentially refine, I get told it's woo-woo and ignored.

I'm also a reiki master.... And the CTO of a 2 person Signals Intelligence startup. I'd like to think I'm not conflating EM with "energy"(occult). Btw I hate that word - there's a definite meaning and the occult way it's used doesn't replicate known science. Maybe we should use Mana until we can define what it is.

This seems like a great opportunity for some small team that wants to get acqui-hired by Apple in a few years for a cool billion. I doubt the domain will get much love because it is a niche product that lives and dies on the whims of a mega-corp. But a small startup could probably bootstrap itself to profitability. Worst case is they get a good five-ten years of being your own boss until the market dries completely or Apple finally decides to compete (but not buy your company).
> Is it possible to generate infinite data and get almost perfect neural network accuracy?

Basic answer is no, but the reason is kind of interesting.

Imagine that the input to the model is a list of facts, initially the facts are just:

* Image 1 has class A
* Image 2 has class B
* etc...

The idea with data augmentation, in a roundabout way, is to add other facts:

* Flipping the image does not change its class
* Translating the image does not change its class
* Adding a small amount of noise to the image does
not change its class
* etc...

However, it is tricky to express those facts as inputs to the model, but it is easy to generate new images based on those facts which the model should be able to learn from. It would likely be more efficient if those facts could be expressed directly though.

So, by generating more data the model can progressively learn those "class invariant transformations", but the model would only reach perfect accuracy if all class invariant transformations were taught.

Another way to "teach" a model these rules is to embed the rule into the structure of the model itself, eg the idea behind convolutional neural networks is to embed translation independence into the model, so that it doesn't need to be taught that from large batches of translated images.

I mean, I cook for my family so I have some idea what goes into each meal. Typical dinner will be rice, some protein, and some vegetables. By far the most expensive bit is the protein. Our staple is chicken thighs which can be had for $2-3/lb. We use maybe half a pound per person (generous estimate), so the protein cost is on the order $6/meal. The rice costs next to nothing, maybe 20c. And the vegetables might be a dollar a head. Spices and such are de minimus. Adding it all up we have about ~$10 to feed a family of four dinner, plus maybe 20-30c worth of milk for each child.

So, that's in the neighborhood of $300 a month for dinner. Again, a generous estimate, because really wifey and the kids don't eat half a pound of meat each. Breakfast and lunch are vegetarian, so much cheaper. This is in inner Brooklyn, so not far off from the most expensive food locale in the US. Hawaii is significantly more, but few other places are. We could make it work on $500/month if we had to, for sure.
On the other hand, maybe this is a kind of perverse benefit of opaque ML systems.

I don't agree with that. With the advent of WSL on Windows you can happily run Linux whenever you want and have all the normal ubuntu pieces available to you without starting a VM. You also get the windows application catalog, which is essentially every piece of major software ever written. With WSL now in the picture, I don't see how a BSD-based OS could beat it given that many applications that an apt install can give you aren't available as easily or at all there.

I also love how fast SpaceX iterates but it does come at a cost. If one design fails, they can quickly iterate to a different design that works. But sometimes that means they aren’t investigating the science behind the failure. Great from an operational engineering perspective but less good from a fundamental science perspective. To their credit, I don’t think the latter is their main role.

Regarding the cost, the aerospace industry needs some scrappy young start ups. However, quality pedigree is a large chunk of the cost of flight and SpaceX has shown some gaps in the past. I think a big question is whether they can keep that scrappy startup up culture while also building processes robust enough to meet space flight quality standards
