There's a video demo of the first paper here: https://www.youtube.com/watch?v=jhOu5yhe0rc

i was trying to build a bit of intuition about this paper by considering a trivial case where there are two classes, and the classifier is linear, in very low dimension. consider the following trivial example:

https://en.wikipedia.org/wiki/Linear_classifier#/media/File:...

in this example, the decision boundary from different classifiers is shown as H_1, H_2, H_3. The "universal" perturbation for each of the three classifiers would be a small vector normal to the each classifier's decision boundary. This paper defines "universal" perturbation with respect to the choice of input from the population of inputs, but each "universal" perturbation is optimised specifically to target a single model (aka classifier).

both H_1 and H_2 do a reasonable job of separating the two classes, but the H_1 decision boundary with the smaller margin is more vulnerable to misclassification if inputs are perturbed by a small vector normal to its decision boundary.

You can imagine translating the input space a bit to the right -- this would result in H_1 misclassifying say 2 out of the 18 data points shown, whereas H_2 (the SVM generated decision boundary with maximal margin) classifier would not experience any errors.
Yes, but it looks like it would still be impossible for the slicer to slice different height layers with this.

Whatsapp paid for itself, more or less, IMO. A lot of people don't need FB to stay in touch with extended family, just Whatsapp groups. They are still in FB ecosystem, of sort.

FB needs to worry about the next quarter so they might ruin this and allow other apps to take over.

Well, the problem is complex. For security you need integrity, authenticity and anonimity/secrecy. Crypto of course is the way we implement all that, via keys and other kind of information theoretic tokens that somehow build upon a pre-shared secret. You need an anchor, a mutual trust foundation to build your secure channel upon.

If you want to put security on/into IP, you suddenly need the whole key management thing, and if you want it to be automatic, you need to somehow cobble together the assignment, provisioning, allocation, publication, revocation of keys with IP addresses (or hostnames, domain names, and you just put DNS into IP).

Eventually it means either you need manual key management (thus IPsec becames a hard to manage old rusty and poorly supported concept from an old era) or you just descended into the recursive pit of all hells of circular dependencies. Sure, it can be done, we can put keys into DNS, and we can use that, but then we're back to QUIC or DTLS basically.

Global here refers to the geographical spread of the service, GKE in this case, measured in regions, not the number of services.

Edit: I saw your point a bit late. It was limited to GKE, which makes my initial comment about "service" incorrect, and it was global, which keeps my comment about "region" correct. On a related note, an SRE from GKE posted on Slack that GCE was out of resources and so GKE faced resource exhaustion as well [1][2] - so it _might_ have been a multi-service outage.

I agree, I think the coffee and food in New Zealand is some of the best in the world. The average restaurant in Auckland is just so much better than the average restaurant in San Francisco (and many other cities I've lived in). I think there is just a really high standard in NZ, and I've had very few bad experiences at restaurants. San Francisco was like playing Russian Roulette. There's just a lot of very mediocre food. If you want to go somewhere with good reviews, you have to make a reservation well in advance, or wait in line for 2 hours. You don't have to do that so much in NZ.

Also curious (as a flagged sibling commenter) about the lack of a HTTPS version of this site—which seems to have user accounts.

The site also has this cute badge in the bottom left: "Powered By En Garde. Secure by Design. Secure By Default".

En Garde seems to be a Linux distro, so I get that they're talking about the security of the server OS itself, and not about securing users connecting to that web server, but surely the former should serve the latter?

Ironically, the very first HN submission from this site is entitled "OpenSSL vulnerability", so they're at least aware that SSL exists, and is related to the concept of security.
> When the browser loads this Signed Exchange, it can safely show the publisher’s URL in the address bar because the signature in the exchange is sufficient proof that the content originally came from the publisher’s origin.

I disagree - there important differences:

- the original server will not see your download request. This will skew their logs/statistics.

- someone else (i.e. Google) will see what you are downloading instead. It's a privacy issue. No wonder Google likes this. They want to know what everything is accessing on the internet. That's why they also run those oh-so convenient DNS servers.

It looks as if Signed HTTP Exchanges are opt-in at the moment. Whether or not your want a CDN in front of your website must be the site owners' decision, not Google's.

NFAs are not a "kind of virtual machine". The "assembly" language for an actual NFA is no more complex than the one for a DFA.

They are state machines that can be in a lot of states at once; that's all. There is a debasement of the term NFA, popularized by Friedl, that "NFA" means "any thingy that implements regex that isn't a DFA". This isn't true and should not be promulgated.
You'd use custom character sets to get you a tiled display of 8x8 or 4x8 pixels (depending on colour mode; 4x8 used two bits per pixel to specify one of two foreground colour specific to the character, or the global background colour), so the display would usually be text (almost no games used the bitmap modes).

So you're copying at most 2000 bytes (40x25 characters + colour) for every 8/4 pixels scrolled. If you're willing to sacrifice a sprite + a raster interrupt every 48 scanlines to cover and narrow the visible area of the screen a bit more, you can reduce the amount of copying even more. Same by not using the full height of the display, as is the case here.

After having a C64 growing up it was always painful to see stuttering scroll, as it was inconceivable to not have proper smooth scrolling in most C64 games or demos.

As a business owner, I would love to use Whatsapp to communicate with my users. Not to spam or advertise, just communicate. The email open rates for our target audience (Indian college students) are abysmal, and SMS is just too unpredictable (but what we end up using because that's the best we've got).

I reckon that there would be similar business owners in my predicament who would just like to genuinely notify users. Just like with email, users can have an opt-out option as well.

I think some of this functionality is already there in their Business API (which is quite opaque fwiw).

On the other hand, I can see how this can quickly devolve into spam if used incorrectly (which is inevitable).

Hi, I'm Max, Data and Back-end Software Engineer that is also having a full-stack experience. Last years is mostly working with cloud technologies and distributed computing in a distributed international team. Feel free to contact me for more details if interested.

I recently removed my hosting from GCP. The pricing is confusing and unbelievable. Their customer service is a joke. I don't trust Google for longterm consistency due to the way they shut their own apps but I let that slide as I doubt they will do that on their cloud services. I have experience with AWS (rock solid, world class support but also costly), digital ocean (improving fast), heroku (good for beginners but also expensive and not as full featured as AWS) and finally Hetzner (too early to judge).
Both of these should be /d͡ʒ/, which is an affricate. In some Polish dialects, "drz" is pronounced basically like that. But it seems to me (I'm not a native speaker, merely an observing linguist) that standard Polish does not in fact form an affricate here, but two separate consonants. Compare "dżem" (with an affricate) and "drzem" (with two separate consonants.)

That's what's so hard to pronounce for English native speakers, who have trouble with word initial consonant clusters (compare the English pronunciation of "Dvorak" as "Duhvorak.")

An added difficulty is that the fricative part here isn't alveolar as in either George or journalist, but retroflex (not /j/ but /ʐ/.)

My favorite Polish word in this regard is drzwi (door.) A word initial triple consonant cluster with an alveolar, retroflex and labio-dental sound, all voiced. Fun times.
How one family built Qualtrics to an $8B exit
Very surprised and happy to see this here.

It's so hard to grasp, completely unthinkable to understand the hardships that people like Dr. Orlov went through, and yet, how they overcame them to do great things, that truly are still pushing humanity forwards. Puts things into perspective when we complain about (relatively meaningless) stuff.

I'm counting at least 20 publications along with Yannis Semertzidis (I had the pleasure of working along him), and a slew of other authors on g-2 and EDM experiments using storage rings.

When all is said and done, my money on where the next big Physics breakthrough will come from is this; muon g-2 is probably the most important discrepancy between theory and observations, in our current understanding of the subatomic world. People are working hard on pushing the boundaries of Precision Physics, to build smaller, but orders of magnitude more efficient particle accelerators, and make history have one more reason to immortalize people like Dr. Orlov.
Rendering a scene is a function that takes lights, camera, geometry, textures as inputs and outputs an image.

This function is very complex and hard to invert. But, and this is the interesting thing I got from the article, it is similar enough to deep learning functions that the same strategy works: We can take gradients of it and optimize the inputs to fit the target output.

So, while we can't compute the 3D model that would generate the target picture directly. We can ask it "How do we nudge the model to make it more similar to what we want?". If we keep nudging it, eventually it will be very similar. The tool will find the exact position of the lights, the textures, model, etc.
How does that work? I thought the fear was you wouldn't be able to swim due to cramps, and drown. That isn't really a concern in the shower. And you aren't really using the same (or any) muscles in the shower, to risk a cramp anyway.

They are a virtual machine because the physical hardware can't be in more than one state at the same time. Representing an NFA as an assembly-type program makes it resemble something like the JVM, in that it looks like an assembly language for a non-physical machine. Virtual=non-physical

I think that has a lot more to do with YouTube having an a very optimized video player, and using ABR streams. That works fine over WiFi in general. If you are doing MP4 pseudo-streaming, thats really a completely different beast.

You don't really want to drop data for streaming video either, sure, in some cases it might not make a huge difference, but if you drop i-frames, you are going to have quality issues.
A while ago I quantified how I spent my day. Every. Single. Minute.

A good day was about 6hr out of 8hr of work. The other 2hr was spent fluffing about - having coffee, hallway conversations, reading HN. Some of it valuable, but not totally focussed.

Then I had a kid.

Never been so focussed at work before. Easy to ignore all the noise, and easy to concentrate on whatever tasks come up during the day. I've found similar traits in other parents.

P.S. Not recommending you have a kid to solve your Deep Work problem, because they ruin all ability to concentrate _outside_ of work.

Citation for this? I'd be surprised if Thompson was first. Runtime optimization was long the domain of Lisp programmers. Blurring the distinction between compile-time and run-time is one of PG's things that "made Lisp different".

This is exactly it. I had burned myself out to the point that I was almost completely unable to work, to the point that I actually was concerned I might need to find a new type of work. Getting all the above in line (or at least to varying levels of better) were key to getting me back to being productive. I still, like everybody I think, have good days and bad days, but I'm back on a sustainable level of productivity overall.

> Consciousness cannot be reduced down to a bunch of changes of the brain's matter.

This is a claim, show the proof then.

> Consciousness is qualitatively different to how the brain functions,

Again, you need to prove this. First of course define what is what and why they are irreconcilable.

We have a consistent theory of the world for the small and large, from nuclear physics to cosmology, and everything in between, and none of them require extraphysical things. Why consciousness would be different?

> and yet no explanation has been offered as to how the brain can magically create consciousness.

I just offered one, and there are probably countless other explanations. The problem is usually testability not abduction of explanations.

> There are literally no models at all that demonstrate, solidly and irrevocably, how particular configurations of brain matter directly translate into consciousness.

We don't have to, we can test and weight hypotheses and eliminate them in other ways.

So far you have offered nothing that would help eliminate this hypothesis (counterexamples or other arguments would be great).
