Last I checked the "tunneling" only works to redirect traffic to a different port on the same SSM managed instance. The tunnel cannot be established with another box in the same VPC. So I don't think you can call it tunneling until they add that feature. Here's the GitHub issue where they discuss the limitation and a workaround: https://github.com/aws/amazon-ssm-agent/issues/208
All approaches need to be considered at this time because we don't know which if any will work. We also don't know what the side effects of the ones that will work might be.

When we get farther along in testing we will have more information and should re-evaluate. Maybe something will prove to work well (we can do a new flu shot in a few months because we have approved the process to create a new one), maybe everything else will fail. Maybe this will fail. We don't have enough useful information to work with now though.

As a 13 year old, I learned to program in Small Basic, a Microsoft educational version of Basic. There was a pdf[1] that explained the basic concepts of programming in 69 pages. I loved it.

I don't think I would've even liked programming had I used Scratch (or Snap) instead of Small Basic. Scratch feels too dumbed-down, limited and clunky.

Maybe Scratch is good enough for 5-9 year olds, but for older kids, I think nowadays Javascript + HTML5 canvas is much better. Javascript lets you see your creation in the browser, which feels like the "real world", because it is. Additionally, it lets you do basically anything you can imagine in a browser. And you code using regular text, which feels much better than colored boxes.

And Small Basic is still better than Scratch I think, even though it seems kind of abandoned by Microsoft.

> Conspiracy theories rely on people being much better at keeping secrets than we know they are.

Most people have no idea WHY they are doing what they are doing! Like the actual true long-term business objective of a task etc. Successful task completion usually requires only technical details and immediate organizational ones. Fake goals are easy to sell to investors and board members by expert manipulator sociopaths (the kind of people explicitly hired and selected for top executive roles).

You can make immense progress towards a goal you know nothing about. You can't leak a secret you don't know.

That's kind of how human societal evolution works, only the bigger goals are evolved/emergent instead of envisioned by some dark conspiratorial cabal. But you can't rule out the latter.

As a society we need to maintain some "immune reaction potential" against nefarious manipulation by entertaining unlikely conspiracy theories too!
Is it me or is this really unclear? I get it is supposed to simplify the back-end for developers but for what exactly? Scheduling tasks? looking at metrics? I get I can install plugins but what plugins? Maybe this isn't for me, but it is unclear to me precisely what scenario this is solving for?

>Languages should stand or fall on their own technical merits.

A nice sentiment, but not reflected in reality. It's valuable to evangelise languages because

1. better awareness of their novel features can pressure more widely-used languages to adopt those features - like the addition of lambdas to Java, Python, etc.
2. otherwise you risk being stuck with whatever people know, forever. "Lack of fluency" is a technical demerit from the perspective of a project lead.

The discussion isn't about university research money and whether that is spent productively, it's about endowments, which are nothing more than investment funds.

The question is whether it is productive to maintain large investment funds unrelated to their stated goals of education and research.

I think the OP would be happier if those endowments were drawn down on research with uncertain benefits rather than just invested in natural resource extraction companies.
A language is a product, like any other. Before it can be used, it needs to be noticed by it's target audience. And to be noticed, it needs to be mentioned.

Sure, you could probably accelerate review from 3 months to a few weeks. The FDA is familiar with rolling submissions where you send data to them as it becomes available.

The code was broken from the start.

Most of the undefined behavior in C arises from traps: if your code, naively translated, would have resulted in a trap, then it is undefined behavior in C.

Preserving when--and even if--a trap occurs is generally not desired, even by most end users. The instructions most likely to cause traps (memory operations and division operations) are expensive, and hoisting them outside of loops, or dead-code eliminating them is incredibly desirable.

When people complain about "broken" undefined behavior, what they usually mean is that they expected to get a very particular kind of trap and the compiler didn't give them that trap.

I worked on one of these projects. This technology has amazing potential for (near) real time detection and monitoring of the spread of airborne disease throughout society. Think shoe box sized air samplers in common spaces that send real time data to monitoring health agencies, alert when a space is contaminated, and so on. The same tech platform can also be used to inexpensively and quickly test individuals.

Unfortunately the funding for continuation was lost in the shambles of the partial collapse of Getinge a few years ago. I was not able to find anyone else interested to continue funding the prototype development when the remnants of Getinge did not prioritise the project.

We had a total funding of ca EUR 5M for the first prototyping project. If anyone has interest and money, I can pull together people and ip.

I'm surprised how little RAM they're giving it. The amount available to the game is only increasing by 50% over the Xbox One X. I think developers are going to struggle to squeeze the proposed visual improvements. If Sony gives a more meaningful RAM boost in the PS5, developers are just going to ship their cross platform games at lower quality on Xbox Series X.
And it's after what had happened in China.

I just hope other countries do not repeat what happens here, and be more decisive in their measures.

> What is the “right” thing to do with UB

It is actually quite clear in most of specific cases, as Linus pointed even 18 years ago:

https://gcc.gnu.org/legacy-ml/gcc/2002-01/msg00418.html

"When it comes to optimization, there are things that are "obvious", and
that will never generate any discussion at all, because they are faster
ways of getting the exact same result, with no question about it. Nobody
will ever fault a compiler for evaluating constant expressions at
compile-time rather than doing the math at run-time and getting the same
result. The two are indistinguishable from a result standpoint.

But optimizations that can change the value of an expression are slightly
different. They should make sense. You should be able to _explain_ them."

"If you cannot explain the results, you end up having to argue about
word-weaseling in the standard, and people _will_ disagree on what the
damn thing means. Because standards aren't mathematically exact things."
Historically, in practice, this guideline never applied to events that directly threaten livelihoods and lives of many of us and our families.

I'm infected. As are many more than any official number out there. I infected my SO, of course. She's having a worse time than me, with a nasty cough that goes right through my soul.

We haven't bothered with getting tested since we'll probably be OK and can sit this one out from home.

I'm a healthy 34 year male without any further conditions. I couldn't find anything about the duration or livecycle of the disease so for those wondering: For me, it started as getting a regular 'flu'. A tingle down my spine, a little light headed, a little hotter. No actual fever. No coughing (for me). No sneezing. And now, day 5, my lungs are acting up. Difficulty breathing. Feeling like I've just ran up the stairs. Last night I woke up out of breath with light pain in my chest.

There are so little accounts of people describing how bad it is going to get or how long it is going to take... I wish more people would share.

I can, however still do remote development work. Besides the breathing issues, my head is clear and sitting still (and typing) is the only thing I feel like doing. Really.

[Edit] thanks everybody for your concern. These are scary times for everybody. Our country policy is "sit it out unless you have fever". I don't have a fever but can assure you I'm taking my temperature hourly and will check myself in when it hits 38°C.
> low fatality and infection rate for average people

Could you say how're defining "average" because right now it just sounds like "me". There's a lot of people who are non-average and have the very same right to live as the average.
This is a very interesting article, with much better illustrations and deeper investigation than the note on separable image filters I wrote in Dercuano. And I didn't know about JAX, and it's very valuable to know about it now. But the article does have some errors.

The article says:

> Optimization of arbitrary functions is generally a NP-hard problem (there are no solutions other than exploring every possible value, which is impossible in the case of continuous functions)

It is true that optimization of arbitrary functions, or even many interesting classes of functions, is NP-hard. However, the definition given of NP-hard is incorrect, and in fact, on modern hardware, existing SMT solvers such as Z3 can solve substantial instances of many interesting NP-hard optimization problems, precisely because they do not explore every possible value. Moreover, it is in general possible (but again NP-hard) to use interval arithmetic to rigorously optimize functions on continuous domains (which seems to be what is meant), as long as they are not too discontinuous; the answer you get is only an approximation of the true optimum, but you can calculate it to any desired precision.

One particularly interesting class of optimization problems — because they are not NP-hard — are continuous linear optimization problems, which can be solved in guaranteed polynomial time using interior-point methods or usually in polynomial time using the "simplex method". Contrary to what you'd think from the quote from the article, going from continuous to discrete makes the problem NP-hard again. There is also a note in Dercuano surveying the landscape of existing software and methods for solving linear optimization problems; there's a lot of very powerful stuff out there.

It turns out that you can efficiently solve an enormous range of practical optimization problems by introducing a small number of discrete variables into a linear optimization problem, thus gaining most of the performance benefit of using a linear optimizer. I don't know if there's a way to get a reasonable perceptual result in a case like this with a linear optimizer, though.

> This is where various auto-differentiation libraries can help us. Given some function, we can compute its gradient / derivative with regards to some variables completely automatically! This can be achieved either symbolically, or in some cases even numerically if closed-form gradient would be impossible to compute.

Automatic differentiation is a specific approach to differentiation which is an alternative to symbolic differentiation and the older kind of numerical differentiation. What JAX does is automatic differentiation.

There are most certainly real estate futures traded on CME. https://www.cmegroup.com/trading/real-estate.html Short selling is possible via inverse REITs and other vehicles.

I'm not really sure what you mean by "all other marketplaces". Lots of marketplaces allow shorting. For example (almost) all commodity markets trade via futures and that means shorting is possible by definition. Grain futures have been traded since ancient Babylon to allow farmers and consumers of grain (eg brewers and bakers) to hedge against adverse price movement between planting and the
harvest.

When I say "almost" all commods trade via futures, for weird historical reasons[1] futures trading in onions is not allowed and so people research onion trading as an example of the effects on a market of disallowing futures trading. The current research suggests that disallowing futures and options trading increases volatility, leading to more pronounced boom and bust as the market struggles to digest information.

For the people here that are confused as to what it does, to me it seems like it's a way of abstracting all the different infrastructure tooling that a large-scale company has.

Consider a team that wants to deploy something to the cloud in a company. They are probably engineers who aren't necessarily well-versed in all cloud tooling, yet they are required to know and understand Terraform, GCloud/AWS/Azure CLIs, Gitlab CI, Prometheus, various monitoring and alerting tools, Kubernetes, Docker, etc. And this is just to deploy their application. Once other resources come into play (databases, queueing, etc), they need even MORE knowledge.

A tool like Backstage allows developers to get a uniform overview of all their resources, regardless of how and where they are running. I'm not sure if it also allows the creation of new resources, but I guess that would be a fairly obvious direction to go in.

It won't solve the need to at some point know a bit more about the technical details about all the underlying tools, but it can allow teams to gradually learn about all this new tooling instead of having to know about everything upfront.

The data is so strange. Malaysia has had an outbreak since well before Italy, with zero deaths so far. Vietnam and Thailand are similar. I'm beginning to suspect that sunshine/vitamin D is a good proxy for how hard-hit different regions are and the huge discrepancy. It's an awfully optimistic theory, since it suggests things will start to get better in the northern hemisphere regardless of intervention and since everyone can individually supplement with Vitamin D immediately.

> WebRTC will work well in a fully P2P way. There's no need for a centralized server unless you have more than 10 users connected.

I wish. With 10 users you have 102 - 10 = 90 different (unidirectional) data flows.

Each of them can run into a different bottleneck where person X cannot hear Y and Y cannot hear W...

And they cannot be monitored centrally (!).

Compared to a centralized location where you would have 10 user-->server + 10 server-->user flows.
