I own two CPAP machines and yes they both implement bi-level/APAP features. CPAP is a bit of an ambiguous term these days; whilst there are technical differences between them, most people call all such devices CPAP machines. For instance,

https://www.usa.philips.com/healthcare/product/HCNOCTN447/dr...

It's advertised as "CPAP & Bi-Level therapy".

To be clear, I'm talking about the ones that implement bi-level pressure. The difference is (as far as I know) primarily a matter of software; perhaps older machines can be upgraded if pricing/selling upgrades is taken out of the equation?

I've had my machines for I think a couple of years now and they were all bi-level from the start. I'm not sure when that started becoming standard or where you got that 10% figure from, you may well be right. But there are 300,000+ sleep apnea patients being treated in the UK alone. If even only 10% of them use modern machines (seems low given how much better bi-level makes it), that's still 30,000 portable ventilators available to be requisitioned at short notice. Sleep apnea patients don't have a critical need for them.
You beat me to it. Sounds like you would be opening yourself up to a variant of CSRF. One user could upload untrusted data that would be fed into an unsuspecting user. You should never feed or consume an untrusted pickle.
If those in power dealt with emergent threats like epidemics, climate change, AI safety, nuclear war, maybe we could trust them with globalized supply chains. But since they hoard profits and refuse to pay taxes, while failing to prioritize the populace survival, seems we may do well to localize into our own communities. Why should we accept global threats and barely reap the rewards of global commerce?
> The first direction is back to a monolithic application running in a VM. Orchestration no longer exists as a problem

Of course it does, VMware makes a boatload of money with VM orchestration. Or you setup OpenStack which is free but a nightmare in itself.

You do not want a hand-rolled KVM virtualization stack. I've been there, I've seen the horrors.

> The biggest, however, is that supervised machine learning doesn’t live up to the hype.

This is the key point. The new DNN approaches can outperform the classical techniques, but only when they can exploit vast amounts of training data. The dramatic successes of Deep Learning all depend on either unsupervised learning against enormous raw datasets (BERT, GPT-2, word2vec, etc) or games, where you can generate unlimited quantities of labelled data by playing the game against your own agent (AlphaGo, AlphaStar, OpenAI Five, etc).
For the developers and third-party publishers, it's a really big deal to have a standard of some kind. It means that they don't have to spend their time making the market: the console makers do that, and then they just sell into it. There is always grumbling about the various overheads of consoles, but as long as it results in unique experiences that people pay for, this state of affairs probably isn't going away either.

And the differentiation of special case acceleration like what we're seeing on these architectures is less exciting on its surface than strapping a high nominal spec to some wild programming model, but it's also a more sane way of achieving next-gen performance.

Cerny's PS5 talk put it this way: The PS1's "time to triangle" (i.e. the basics of the asset pipeline are proven and real development can commence) took 1-2 months, the PS2 doubled that, the PS3 doubled that again, and everyone protested so much that they got it back down to 1-2 months for PS4, and with PS5 they are aiming for under a month, which is actually really ambitious for any development platform!

Also, I sense that the special-case approach also has neat goodies in store down the line because console devs always end up abusing hardware features to get results beyond the original requirements. There's stuff in the PS5 arch intended for DSP code, for raytracing, for decompression, and probably other things too, but most of these things are a little bit more open than just being an accelerated single-task function. I haven't seen what they're doing on the XBox end yet but I wouldn't be surprised if it has some good details to geek out over too. These functions are uniformly win-wins since they give an immediate result that accelerates something common, and then we find out what else they're good for later. Sometimes they aren't, but it's common that they surprise.
> Low framerates are almost always completely unrelated to optimization.

I would be interested to see a source on this.
Logically, an array of booleans and a set of integers are equivalent. So in the Druid developer community we usually use the terms interchangeably. But to be precise, our indexes are all stored as bitmaps and compressed with bitmap compression libraries.
Bitcoin and cryptocurrency markets were shocked last week when the bitcoin price briefly plunged to under $4,000 per bitcoin, sparking fears of a crypto wipeout.

The sudden fall was led by Seychelles-based bitcoin and cryptocurrency exchange BitMEX, with the bitcoin price dropping to a low of $3,600 on the exchange before it was closed for "maintenance."
It's true at a lot of places.

I know one developer who is obviously planning to go to Amazon because every single application he works on immediately starts with looking at which AWS services he can glue together. I'm to the point where I want to create and AWS bingo card and when hes on a conference call, pass it around to see if anyone wins by the time he describes some solution set.

"Well I'm starting with [AWS service here] but it doesn't support [major, normally functional breaking requirement], so I'll use [this crazy set of JS NPM packages] to do the work in between"

Wish people would develop solutions, not resumes.
And with MS saying that exclusives would be for XBox and PC it makes more sense now to have a gaming PC and a PlayStation.

Fling's Guide to Working from Home
On bare-metal boot times are drastically different. OSv was sub-second while our Alpine images were 3-5 seconds depending on what services we needed. However, we were focused on running our system on cloud VMs, not bare-metal. In the cloud you can't get a VM to start booting in less than 20-30s so that order of magnitude difference turned into, at most a 10% difference in boot times.

In 2017 we measured the restart time in of our unikernel images in AWS to be 22 seconds, all that time was waiting for Zen (2017... no KVM yet) to get around to getting to the place where we could run our image. So for our use case, the boot time didn't actually matter, it was far overshadowed by everything else happening under the hood.

I should say: Unikernels do have their advantages and should be used in areas that can exploit those advantages: Fast boot, low attack surface, way better performance for some workloads. We had trouble finding the specialized customers in the cloud that needed any of a unikernel's positives so badly that they would take on a unikernel's shortcomings.

Yes, that is what we do and what I like about SQLAlchemy for Python. We use the ORM for like 90% of cases and drop down to its SQL abstraction underneath the ORM.

The last time I used Django a couple of years ago that was one of the bigger pains for me: It was either the Django ORM capabilities or raw SQL, not much in between. Or maybe I was just unaware of how to do it better.
I don't suggest taking anything to anyone. You should research a supplement and compare its benefits and risks based on your physiology. There probably isn't a one size fits all answer with most phytochemicals. I personally use it to boost the effect of TransResveratrol.

they are too ambitious to their capabilities. and pivoting all over the place to mobile etc just makes it even worse.

CPAP machines technically can't but CPAP has become a generic term that also encompasses bi-level/APAP machines that can swing pressure fast enough to track inhalation/exhalation. Both mine do. They're not that old but they're not top-end either.

I don't know how many active machines are pre-APAP/BiPAP/A-Flex (there are different names for it). A comment below says 90% but this seems very high to me.

I wonder if it's possible some doctors don't realise the machines have this feature or it's importance? When I first was prescribed CPAP the machine did not come with bi-level flex enabled, it made it very hard to tolerate. I pushed through it for months but when I "cracked" the doctor-only DRM (i.e. looked up the cheat code on Google) and enabled A-Flex it instantly became way easier to handle the machine and my AHI scores were super low; big success. Doctor was quite happy with my altered configuration. I was just surprised such a basic thing hadn't been explained to me.

I suspect a lot of CPAP machines support bi-flex but it either isn't activated or could be added via a software update. I don't think you need extra components.

>> They're pretty close to what you'd find on a top tier smartphone really

A top tier smartphone from a few years ago, maybe. My not-so-top-tier phone has better specs than my Switch.

I held off from getting a Switch until this past November, and it was a weird product called Ring Fit Adventure that ultimately made me pull the trigger.
If they keep going this way, it's probably only a matter of time before a common "gaming box" standard is set and these companies just become manufacturers against this standard.

It's happened before to various levels of success.
My guess: regardless of which party wins the presidency in November, there will be as much accountability for this senator and others like him as there was for the George W. Bush administration officials who lied the country into war and implemented a program of torture. That is to say, none whatsoever.

> I've seen numbers that suggest the US has 2.5x ICU beds per capita compared to European average.

The number per capita isn't the key thing, the number in excess of normal use available per capita is. If the US has and uses more because it is worse at keeping it's population off ventilators normally, that doesn't help.

> It also costs 3.6 _trillion_ dollars a year. Surely at least some of this money contributes to it being less "fragile"?

No, the cost is directly a consequence of the main source of the fragility, a financing structure that, among other inefficiencies, promotes micro-optimizations around short-run, single-actor financial efficiency in a system with multiple no cooperating actors rather than systemic efficiency where it promotes any kind of optimization at all.
This is a similar argument between say your own server farm and AWS. Consoles are guaranteed to work correctly and always have 100% compatibility. You don't tinker or deal with any headaches, you just play. For many people, that is worth the extra cost.

Depends how wide your definition of 'physics' is. We have a couple of environmental scientists at work that use it to model water pollution for example. The big win is that they can basically just type in their differential equations exactly like they would write them on paper and have the answers simply pop out.
As someone who started using Mathematica only very recently, I found The Wolfram Language:
Fast Introduction for Programmers [1] very helpful. It's the quickest way to get started with the Wolfram language if you've seen a bit of functional programming before, e.g., Python's map(F, x) is equivalent to Wolfram's Map[F, x], reduce(F, x) equivalent to Fold[F, x], etc. There's also
An Elementary Introduction to the Wolfram Language by Stephen Wolfram [2,3] which is available freely as Mathematica Notebooks, although I'm yet to read it fully.

I'm ridiculously busy right now, and I don't have the time - sorry. What I will do is point you to the resources I've been using:

http://opencircuitdesign.com is the primary resource, which gives you layout, design, proofing, and setlist generation.

I'm not aiming for anything even remotely state-of-the-art, I'm looking at a 180nm design and even that might be pushing the hobby funds. You can get "shuttle service" at various places to share a wafer, or you can use efabless (link on the magic page above) to do a lot of the work for you, at additional cost.

The guy who for years wrote and maintained Magic (the layout tool) now works for efabless, and he's a great guy - especially if you submit patches to him :)

It's a lot of hard work, you have to worry about all sorts of things you can take for granted in an FPGA (clock routing, i/o bonding and pad designs, oscillators for clock multiplication etc. etc. and yes etc. again). But there's not many people who can say they taught themselves how to make an ASIC :)
Germany is rather odd compared to the other countries with its adoption of broadband tech - for example you see a decent bit of FTTH/FTTx in NL, NO/DK/SE (muni owned, early adopters), etc.

Then you go to Germany and it's mass of DSL (and some areas cable). I wonder what happened or why?
> Framerates are determined by how much the developer wants to push graphical fidelity/AI etc.

Framerates are determined by how much the console has to process before it can display a frame. Apart from possibly setting an upper bound, FPS is a variable developers do not directly control.

The issue I am pointing is unintentional drops in framerate caused by game events. A developer can spend time testing their game, and tailoring the amount of processing each possible configuration of events and objects require so that at any one time, it doesn't exceed the processing budget allowed by the target framerate. That is optimization. If you do not do it, the framerate will be essentially random.
Interesting. Sorry to hear about the layoff, hope you land on your feet!

Depends entirely your valuation formula.

If six months of networking yielded a $300K/year job, lasting 3 years.

If your current income is zero, with mounting debt— the time invested is well worth your ROI.

Domain Name Generator Using OpenAI's GPT-2
Hi! I have recently fine tuned the 355M GPT-2 model on top 100.000 domains and their content to generate domain names. In addition to the domain name it also generates what the company is about. Sometimes it just makes up some new business domains out of nowhere. Maybe I should brand the product as random startup idea generator :)

This is encouraging exactly what I dislike about the current ML-in-industry space, namely the fetishism surrounding being able to describe the rote steps of an algorithm and all this "X from scratch" stuff. It's good to know "this algorithm is used for binary classification" but there are so many subtleties to how the data is reckoned with through these algorithms and how that particular representation of the problem maps onto your current business task.

For instance, I'm doing a project that involves binary classification but I already know that linear SVMs would be a terrible idea because the hinge loss only focuses on two data points and essentially ignores all the rest. Logistic regression is much more appropriate for my needs because it is directly optimizing the estimates of probability of belonging to one class or the other, by virtue of that literally being the definition of the objective function. This, though, doesn't really sink in without significant practical experience, and definitely wouldn't stick if it was recited to you from the front of a lecture hall or one of a couple hundred flash cards.
yes it is. i pay for 4k and my country has no problem with internet speed (we do have Gbps connections at home). this is not something we need.
