Hello HN!

This is Atanas (twitter.com/kozarev_atanas) working with

- Dr. Chris Williamson https://williamsonchris.com/ and

- Prof. Mark Ryan https://www.cs.bham.ac.uk/~mdr/ Centre for Security and Privacy at University of Birmingham

on PAD.

We have released the beta of our API for PAD. PAD is a system which allows you to provide secure access to confidential information shared between two or more parties - you can share the ability to access a secret without automatically exposing the secret itself.

At the core of PAD is accountable decryption, which offers an alternative to transacting in complete openness or complete privacy. Anytime you need to encrypt and share a piece of information where the rules of who, when, and/or how that information should be decrypted and accessed cannot be simply codified, PAD can help to improve privacy and oversight of the information.

To try PAD, please complete the short sign-up form [1]. We will provision you for the API as soon as we can, but we are a small team and this is a manual process so please bear with us if there’s a short delay.

See our developer documentation [2], and our launch blog post [3] for more information. In particular, some use cases for PAD are described here [4].

Feel free to comment here and, Chris and I would be happy to answer questions.

You can follow our progress on Twitter [5], and if you want to get more involved, we have also created a Discord server [6].

Today we published a whitepaper [7] describing PAD incl.

- The protocol in detail: e.g. how we secure, request, and recover a secret
- Risk analysis and security against collusion
- The PAD system: accountability ledgers, trustees, validators, encryptors and decryptors.
- Applications, future functionalities, and collaboration

Best wishes,

Atanas, Team member at PAD

everyone in my school net send bombed everyone all the time. Im not sure how they didn't figure out how to just turn it off.

but i remember you had to do it from a library computer, because it said who it sent it from. so you had to do a little drive by walking net send as you walked out of the library to not get caught
Meta: Unsure what is happening on the front page today. This isn't even a link to the article[1], and somehow it rocketed to #10 in under an hour. A nearly 2-year-old announcement about SHA-1, posted 20 minutes ago, is in 3rd place.

Nuclear plants are also "intermittent" - the average US reactor spends 32 days offline per year.

Does that mean a grid relying heavily on nuclear needs massive amounts of storage?

No - it means you need to have redundant capacity which is the solution also used for wind and solar. The benefit of nuclear in this regard isn't that it's "non-intermittent" - it's that the most common failure modes for a nuclear nuclear are statistically independent (except when it's not like in a natural catastrophe situation - like Fukushima).

But as a grid operator trying to match supply and demand, it's just a variant of the same problem.

The solution preferred by grids heavily dependent on wind for example is simply to over-provision wind and use de-rating while maintaining natural gas capacity reserve (which is relatively cheap). This approach is relatively proven at this stage with some European countries deriving around half their electricity from "intermittent" renewables.

"This disaster will have been preventable. All of the warning signs are here, yet no one will have done anything about it." Indeed.

That makes the sentence quoted by GP sound like a category error to me. Developing better algorithms and developing more useful models to run on those algorithms are not an "either/or" situation.
I think you are thinking of reserved concurrency - with reserved concurrency you can only run as many instances as you have reserved. With provisioned concurrency you can run as many as your quota allows but you are guaranteed to be able to handle as many concurrent instances have provisioned. Neither one of these are going to help you with cold start times, it is not defining the number of instances running, its just reserving a portion of quota so that they can run. Where provisioned/reserved concurrency comes in useful is keeping a run-away lambda function from starving out other functions either by guaranteeing a portion of the quota for the other functions or keeping a function from exceeding a number of concurrent executions.

The "ping" technique you mentioned is one way to keep a function warm but if lambda decides to start a second instance of the function because the hot one is handling a request, then that person is going to take a warm up hit and nothing you can do about that.

If you are really latency sensitive then lambda might not be the right choice for you. You can get a t4g.nano SPOT instance for about $3.50/month and you can keep that warm, but that is probably a whole lot more then you are paying for lambda.
Typically 15 years.
Neat story, and this is clearly harmless. But isn't the most basic, fundamental, number one rule of security/pen testing to try to break into a system (no matter how weak) if and only if you've been given clearance beforehand? Why doesn't that hold here?
I used CACLS with an Office hack in NT / 9X to copy homework. Never got caught for that.

They got me on propagating computer games through the network using shared drives the teachers were supposed to use for homework.

We had BNC network cables in those days and the entire building shared a single T1 line for several hundred computers.

The world has changed.

Glad to see a cooperative and supportive academic administration, and I'm sure the thoroughness and planning that the team demonstrated made it easier on the administration.

The sheer amount of testing and verifying no major impact to academic testing took place probably helped, and cleaning up after themselves and documenting their finding and reporting it to IT was a cherry on the top.

I like that the administration even requested that the team brief the district IT on the "attack".
Its funny with this mask thing. In Sweden we never had very wide mask usage, and I'm not sure what our "CDC" is saying about masks now, but I still think they are very sceptical tbh.
> In California now they're using fracking wastewater on crops

That's not what your linked article says. The article says treated wastewater is being used. That being said, it appears to be in dispute if the water is treated enough, with the water district claiming that it is and an environmental group claiming its not.
Probably helps that "We prepared complete documentation of everything we did, including recommendations to remediate the vulnerabilities we discovered. We went a comprehensive 26-page penetration test report to the D214 tech team and worked with them to help secure their network."
I like to imagine myself explaining the subject to an audience. Questions appear automatically and I study to answer them all. Depending on how hard I want to keep that information I force myself to do these imaginaries lectures often.

Adobe is competent in some regards, but seemingly not in others. Flash was riddled with bugs and vulnerabilities, so in this regard Adobe seems incompetent, or lazy at best. But the flip side to this coin is the reason flash became so popular; artists and designers saw in it a tool that scratched their itch well, not knowing or caring about the technical shortcomings. In this particular regard, making software that designers and artists like to use, Adobe seems to have a track record of competence.
There is a big difference between Scientists and Political Activists with science degrees.
Yes because we learned from Chernobyl and Fukushima. The reason nuclear is expensive is because they protect themselves from war or terrorist attacks by drills, policies, strengthened structure and alertness.

Actually, if you are in a war or you are a terrorist, there are much more high value targets than a structure with 1.3m thick re-enforced concrete plus 1cm thick steel dome.
One thing I can't understand is why Adobe is so insistent on keeping Flash really actually dead by saying it's "unsupported" yet still keeping the sources to themselves. If they aren't gaining anything from it anyway, why can't they just open-source it? I mean they won't lose anything either by doing that, right? The community would fix all the bugs eventually. Probably quicker and better than Adobe, too.

Wow no. Extremely poor article. No hard data to back anything up. But anecdotally from my own experience, most working devs are late 20s and above.

This stereotype of younger devs was more valid in Web 1.0 to Web 2.0 days simply because there were fewer devs in the pool but today the field is well saturated
It's a set of interrelated issues. Much of the US is zoned/regulated to be friendly to drivers and not pedestrians. For an egregious example, most of Downtown LA (so not the suburbs) you can walk for 30 minutes and maybe only see 5 different stores. Because of this, American culture has stopped talking about walking. As such for a lot of Americans, walking for 30 minutes to get somewhere is absurd culturally, but driving 30 minutes to go to a store is much more acceptable.

You can see the effect even more when it comes to recreational hobbies and sports. Americans don't really just walk or bike around. Walking and biking/cycling are usually specific activities, so most Americans buy special exercise clothing or exercise gear to go (by car) to specific spots friendly for walking and cycling to perform their recreational activities and come back. Walking is still a popular casual activity in urban areas but in a lot of suburban areas there aren't even the sidewalks in place to make it safe to walk around. Most Americans only really dress/prepare for the walk from their house to the car and from the car to the store/office/destination, then back if they're not specifically out to perform their recreational athletic hobbies.
Credit where credit is due, we all WISH *nix had something like PowerShell. Passing strings from program to program is a pain, passing around .NET objects instead is a great step forward, as can be seen by the several attempts at similar shells passing around JSON objects.
Crunch munch munch munch ... Crunch munch munch munch..

What did you say ?
Yeah, fair, I still don't know what them recommending this earlier would've done though. It just would've made the shortage sooner, right? It seems that's what they were trying to prevent. I do get that people don't like that they were lied to though, and then mandates were hard to follow when implemented, if people couldn't acquire masks. The pandemic exposed, and continues to expose, issues with our supply chains. If there was an abundance of masks to start with, I don't think the government would've flip flopped on masks in the first place, but since supplies were what they were, I'm not sure there's a good answer here.
TIL there is an Elk Grove that is not in California!
Depending on region, a 30 minute walk can be dangerous to one's health due to hot, humid temperatures or smoke inhalation.

(Besides that, a 30 minute walk can be inconvenient- the stuff you're buying might not support being carried for 30 minutes. I tried to get a friend to consider giving up a car-based life and they asked me how they're going to move their stuff for LAN parties and gun hobby related activities.)
I suspect this number is inflated for the purpose of showing off the kingdom's or the religion's wealth and power.
The rule does apply. Also, it was a senior prank, which by definition involves breaking the rules.
Think of it like water flowing down a hill. The heat is in your room because it flowed down to a cooler space with less energy, just like the water flowed down to a space with less potential energy. Moving that heat back to a higher energy area, back outside, is the same as pumping the water back up a hill. It always takes more than one unit of energy to move one unit of energy back “up”. You can only capture energy if it’s moving “down”.

You might enjoy a physics course, especially if you enjoy calculus, although an entry level course won’t require it.
> if you want a PS so badly, why not get a used one or older new one on ebay or amazon: like maybe one of the previous versions PS4, PS3, PS2, PS1 or maybe another game system? it'll probably be whole lot cheaper too and you don't have to pay extra.

Well, for several reasons you may not have considered:

1) I need you to find me a listing for a "used" ps5 that isn't broken, double the retail price of a new system, or a flat out scam.

2) You seem to be laboring under the delusion that the only reason someone would upgrade to the ps5 is for the latest and greatest hardware or to simply have a Playstation console. Instead, you should consider that there exist people like myself who hope to upgrade because of games that are exclusive to the ps5.

Agreed that a black and white approach here doesn't suffice. You can be concerned about over-reach and censorship, and concerned about the propagation of harmful information or misinformation.

My question to those screaming censorship, which I have yet to receive a good answer on, is where they draw the line. The well known line for traditional free speech is incitement to violence or shouting fire in a crowded theater. If controlling vaccine misinformation for the sake of public health is censorship, what are the cases where controlling the propagation of patently false information isn't censorship?

The internet has opened the floodgates for bad actors to flood the airwaves with bad information, whether for their own gain or for malicious purposes – to the point where the sheer volume of bad information being pumped out makes "countering bad speech with better speech" a losing battle. The algorithmic bias towards controversial topics inherent in the systems we have created are only exacerbating the issue.
From what I understand - the demo was using a completely different set of technology from that which eventually came out.
Up until OP starts working out the frustrations of RTSP it was pretty much a yawner "scan for ports, http to them, see if sumthins there and unguarded". But the perseverance to make a prank work like that with a finicky protocol across a wide variety of different OEM hardware is really exceptional!
That sort of time could be easily reached with lambdas that require VPC access, where a new ENI needs to be provisioned for each lambda container. I don't think alive seen 30s, but could easily see 5-10s for this case. And since this is required to run an isolated DB that is not some other AWS service, it isn't that uncommon. I believe they have since improved start times in this scenario significantly more recently.
That was our company thesis, that carbon was systematically underpriced and we wanted to amass a portfolio of carbon credits before that was corrected. But you still need to provide project investors with a competitive ROI if you want to build the thing.
The executive order is for all employers that employ more than 100 workers, not federal contracts. But even federal contracts can't be amended by executive decree once they are signed.

But if you are so certain that the EO is constutional all you will need to do is wait.
Even if some physical/scientific solution was discovered, still remaining is the issue of politician and public (voting, lifestyle) support, much like we see with vaccines. Running a study of that in parallel with scientific studies seems like the logical thing to do, yet another lesson we didn't learn from covid I guess.
Probably something to do with the nearly 2000 sq mi of "exclusion zones" from Chernobyl and Fukushima. (Which, admittedly, is great for the local wildlife.)

"Ah yes, remind me how many windmills we would need to produce as much energey as a NPP?

About 1500.
I may be wrong, but I’ve felt for a while that there are some pretty strong vote rings avoiding the HN systems. There’s always a lot of strong downvotes or upvotes for specific subjects, but not that many voices in comments to go with them.
This is a really bad take, with a limited understanding of how Ethereum nodes and smart contracts operate. I clicked hoping for more...
I almost guarantee that he had something to do with those racist/sexist comments. I find it unlikely that someone else would be controlling an account under his name publicly for YEARS without his knowledge.

Even if he himself didn't post the comments, he must have known that it was going on at the time and probably knows the person who did do it.

"I didn't do it - it was someone else under my name" is the equivalent of "the dog ate my homework". I definitely agree with you - there are key missing detail - conveniently so.
OP doesn't bring up the different temperature and pressure differential of heat sources. That's a huge red flag. For all we know the CTO role at that company was entirely focused on keeping the staff laptops running and is largely disconnected from the fundamentals of heat to electricity generation. Why the hell would she (or he) ask here when (s)he has current or former colleagues in the industry to ask.

My BS detector went off immediately.
> The technique that the researchers developed is quite complex and required two months of computations on 900 individual GPUs.
People thought fossil fuels were a finite resource back then?

I mean, I wouldn't be surprised if someone thought that, but given the frequency with which oil was being discovered, it seems reasonable that people would have assumed it to be effectively unlimited.

which tells the secret of when to stop when you're doing "early stopping", something I've seen many modern deep learners fail to get right.

Off the top of my head I would say the fundamental math about deep networks is not really new. Most of the work in that field is pretty ad-hoc and not a lot is proven; probably people that are proving things are using difficult graduate-level math but you don't need to go there.
The whole effort to remove hate speech is due to governments demanding they do so (sometimes with stiff penalties). You're just seeing a reflection of what government legal pressure they face.

There was an excessively annoying kid in my high school and I learned to send remote commands to any computer in our lab, so I sent a command on loop that continuously opened his disk drive (it would automatically re-open after closing), and if he was particularly annoying I would shut down his computer.

I never once got in trouble for it - the teacher would ask the class, directly looking at me, from time to time to stop it, but I never got in trouble.

I imagine he was just using those announcements to get me to stop from time to time, but knew this kid deserved it so he never did more than that.
It somewhat amuses me to see the parallels with Google Glass in this regard. I worry the enterprise market may already be quite crowded, though, and there are ample niche vendors specializing in AR for different use cases (construction, manufacturing, medicine/surgery, etc). I don't know that Magic Leap isn't a year late and a dollar short.
That might work for a bus out in the open, but GPS doesn't work well with a lot of nearby tall buildings, or for subways underground.

Maybe they are using GPS and silently failing in all other situations? My point is that it's nice when it works but could use some improvement on whatever method they're using.
FWIW, one way in which you lost me early on was framing it as VRU vs driver. I don't see it in such simple terms. There are road users. It is not always the pedestrian that is killed. Sometimes it is another driver. And pedestrians can absolutely be the cause of a wreck where the driver dies. Not to mention, someone can be a VRU now, and a driver in a few minutes, then a VRU again.

There are lots of good reasons to make roads safer, lots of methods for doing so, and none of them require making drivers the villains.
Nobody says that overgeneration is free. But for example if your wind power costs are $20/MWh and your nuclear power costs are $80/MWh, even 100% overgeneration capacity for wind is still cheaper compared to the nuclear alternative. And if it achieves the desired effect cheaper than storage, then it will be preferred over storage as well. The optimal ratio of storage and overgeneration needs to be modeled for every grid independently; I believe the article I mentioned models it for the German grid.

In practice, though, I expect that you won't even get energy waste from overgeneration if flexible energy consumers like BEVs or flexible hydrogen electrolyzers are connected to the grid. These will account for a major portion of electricity consumption and it will be possible to move their consumption around very considerably.
