>"Data security is where our intuition formed from real-world experience falls down.

Very sad to see the closed-mindedness in this thread where users reject a very valid and apt comparison because it does not meet their preconceived notion of these models.

Ironically the only factor that "knocks down" our intuition is you, when you reject points without considering them. You knocked down my valid point not fairly, but unfairly, waiving it away without consideration.

>"Physical theft in a store is bounded by many factors, not the least of which is someone actually has to carry out the goods without being intercepted. Stores deploy additional security mechanisms to alert on high-value merchandise that is small enough to easily conceal. So stores' losses are bounded by the impracticality of "scaling up" the theft attack."

Very very sad that you cannot see the obvious and basic similarities.

Do you believe it is as simple to steal 1TB of data as it is 1MB? --- So you agree there are obvious "bounds" to digital that mirror real world?

How about content type? Do you think it's easier to steal data replicated on their general purpose CDN than say account data hosted internally at one of their data centers?

Do you believe that online services don't deploy additional security mechanisms on high-value data?

Do you not realize that digital data losses are bounded by the impracticality of stealing large amounts of data, too?

I hope that users reading this thread will read + think more than they reject + talk because it's very depressing seeing this response here.

Most of Tor usage is as a proxy back to the regular internet. I don't think you meant to, but the term "content on Tor" can be misleading in that respect, restricting the discussion to hidden services when the context is often Tor use in general.

"larger and slower"... That must be why they say "it's turtles all the way down"!

That's a rubbish statement that you quoted. Some tribes often fought with each other, others didn't (eg. who were the Khoi-san people at war with?).
And often, the ones who did fight amongst each other lost more in terms of lives and resources to colonizers than anything else. And not just because of fighting. Colonizers also brought with them diseases like smallpox etc that decimated native populations.
But then might there not need to be a certification for other areas as well? Might be a hard thing to set up.
The one point that I think worries me that the author makes is about how much the electric car revolution will really cost in terms of raw materials and lifetime CO2 and environmental issues.

Is there anything accurate on the actual pollution cost vs a say a VWs (irony intended) lifetime emissions; it seems incredibly hard to calculate!
I'd love to see an option to see the original design of all the mails.
That’s exactly what I meant! We (my family being German) found it on one of our shopping trips at Bilka Kolding (we sometimes drive up there), and just bought one.

Sooo awesome.
All you're doing is highlighting the fact that "evil" is a subjective word and everybody applies it slightly differently. And I think that when we have a conversation like this thread has become, all we're really doing is taking a straw poll of other peoples' definitions to see the lay of the land.

So- you get that my definition of evil places actions on the same level as results- and I get that yours doesn't. I'm not sure that we can do anything but agree to disagree.

>Elon Musk’s latest four-wheeled exercise in rent-seeking

How is selling a car rent-seeking? It's pretty much the opposite extreme as far as I can tell, unless he's making the argument that Elon is rent seeking by buying up the raw resources for making lithium batteries (and even that is pretty weak).
I don't think the trend toward having devs handle all the ops is a good idea. Ops teams, for good reason, tend to be way more conservative than devs. Plus I don't think it is effective to constantly interrupt dev teams with operational issues.
May be he is talking L2 charging. On Bolt it is 9 hours, so Model 3 will be similar on 240V plug.
> Thanks. `await` in Perl 6 is blocking. I'm guessing Task.WaitAll maybe does (some of) what `await` does in Perl 6?

Depends on what you're trying to do. `await` is just a keyword that means the CPU pauses this method until the result comes back and does some other stuff meanwhile. You can omit the keyword and method completes immediately while the other stuff gets done automatically if you dont care about the result or whether it actually finished/errored/etc.

In C#, you can use Task.WaitAll() which will block the current thread until all the async tasks are finished or use Task.WhenAll() which itself is an async task that returns when all the tasks you pass in are finished (and probably the better option in actual production code).

> Are you saying ordinary synchronous C# code looks like this:

No, normal foreach is a language keyword/construct that just looks like:

foreach(var item in someListOfItems) {
DoSomething(item);
}

Parallel is a static class that implements parallel processing and is part of the TPL (Task Parallel Library) that has been available for years before even the async/await keywords were built-in. You can use them both in combination to manage async tasks and also do more explicit parallel threading yourself. It all depends on how much control you want and your objectives. I suggest looking at the link I posted to see some of the available options.

This is a good overview to the async/await in C#:

College is a huge waste of time. But then again so are a lot of jobs.

If you don't care about college because of all the bullshit and dumb people, just wait until you enter the workforce!

Probably best to go ahead and go for most ambitious people. Besides, those years are a lot of fun if you do them right. It's not a great system and certainly not the best way to learn, but for the foreseeable future it is the most sure path toward increased financial success. But I do understand your frustration... I barely got out myself because of similar experiences (in a different field but same type of nonsense).

> When it is handed over the SREs get all the keys to the kingdom and have the rights, responsibility and ability to fix bugs in the software they're running.

Bug fixing is still the responsibility of the developers, which isn't to say that SRE won't help out at times but it's not their role.

> If you have legacy codebases run entirely by ops people who don't have any ability to maintain the codebases then you aren't doing SRE.

An SRE is not a maintenance engineer. Service ownership is always a partnership between SRE and developers. If there's no developers, then there's no SREs.

I don't really understand the matrix substitution used, but the fact that the genetic algorithm works like it does seems to suggest it's about as secure as a Vigenère cipher (working on bit strings). Unless the genetic solver doesn't provide any speedup and is just ignorantly used instead of a brute force approach. It's extremely unlikely that Salsa itself is vulnerable though.

There is a rather interesting science fiction movie, called "The Thirteenth Floor", that explores this concept, in fact if I remember correctly it talks about nested simulated worlds.

This makes perfect sense to me, if the theory that we are living in a simulated universe is correct, the exact same logic would apply to the beings that are running the programs to simulate us and so on, ad infinitum.

Apparently there are trade offs when using electric cars, which apparently makes them terrible. Inconvenience for certain types of driving means they're just awful.

There's no silencing of 'shit talkers' by 'control freaks', just push back to a poor argument.

Electric cars are good for commuting, and poor for long distance. There's nothing more to it than that. I commute on a bike and mostly want a car for long trips, so I won't buy an electric car. Somehow I can accept that fact without deciding people who want them are idiots.

What are you trying to teach them? I went through a coding school called Founders & Coders, one of our one week projects was to make a stack overflow clone. We really enjoyed it.
Correct, 48VDC exchanges volts for amps. Basic electrical theory states volts * amps = watts. We measure computer power usage in watts for a reason.

48VDC isn't sufficient to vaporize a metal screwdriver at the amperages used in most 48V datacenters, however, I know people who work with higher voltages than that, and they own expensive ceramic tools just for safety reasons. If I personally ran 48VDC, and my workers requested ceramic tools, I would not hesitate to expense those.

And yes, if you're working around DC >12v, you should be seriously using every method available to make sure you don't become a conductor, including only using one hand at a time to touch power relays (to avoid having your heart stopped).

Hi,
I would say it depends on the kind of code you are working with. Our code is quite branchy and somewhat complicated.(3d rendering software)
For simpler code that does e.g. lots of the same thing on a regular grid, OpenCL might work better than it does on our code (targetting CPUs).

How about using a bitlist/bitmap/bitset/bitstring/bitarray, maybe even a compressed one, like roaring-bitsets ?

Edit: question: is there any type of index better than compressed bitsets when you have per-column index and you want to AND,OR, basically combine them ?
I am a junior at a target CS school in the US. I'm currently studying in Europe at Sweden's KTH, reputed as one of the top engineering schools in Europe/Scand. I loathe all the "EUROPE IS SO MUCH BETTER!111!!!!!" posts everyone makes because I always feel like it's out of touch and hip to say to. The culture here in Sweden is way more relaxed. This is definitely NOT a catchall, but a catch-some, sort of statement, even if I do interact with mostly Masters students from across Europe, probably >50% of my classmates. It's not as rigorous here, and it's not as if the students are still "killin' it!" because I have been in exclusively project classes, and the projects presented have been pretty mediocre. Most students aim to pass. Few students in my MASTERS LEVEL classes (bear in mind it's 4/5 year students unlike in the US) have NEARLY the chops of any kid in my undergrad CSE program, and I've been in 4 groups now with around 30 students and obviously talk to many more. I'm frustrated because everyone hates on this system, but it's allowed me to perform so much better technically than any of my classmates here that I've interacted with.
Also, His comment that "you may need to reinvent the wheel sometimes" applies to so few. I am going to be designing REST APIs or similar for years, I bet. I am going to need to know reasonable HCI for years, I bet. So many people don't learn the right idioms. The right design patterns. Every internship I've had has "man, sucks that we taught ourselves this technology instead of learned formally" or "man, this stack was built by non-engineers and is an un-maintainable monolith." I can't take these statements seriously. You can learn programming by yourself. You can be way better than I'll ever be through self teaching, but I feel like this is similar (but to a much less extent) logic to, "Bill Gates dropped out of college!!!11!!!!", and it's just NOT true for MOST people. The comments before me are SO right that it's career jeopardizing.
Most anyone able to charge market rates might be more motivated to reveal they've been contracted to do this than to actually do that.

I often drive to Denver or Galveston several times a year. 600 and 500 miles. So if the initial charge holds 300 miles, I would need probably 2 20 minute stop for Galveston and 2 30 minute stops for Denver (if I could find super charging stations on the way to Denver).

Given that I often stop for far longer than that, far more often, just to stretch my legs, I could easily work around the Model 3's charging requirements.

Well, I can't say that it's deliberate, but it's definitely some "interesting" choices.

A reasonable Salsa20/20 implementation on a modest processor encrypts on the order of 400MiB/s [0][1].
So that the author went to the trouble of halving the number of rounds and changing the word-size when there are perfectly good and plenty fast off-the-shelf Salsa implementations strikes me as rather strange. Surely this is not the bottleneck on most employee's machines.

And then there's the apparently tiny keyspace used. You could argue that this makes the key more "user-friendly" (!), but just a hex representation of a random 256bit key would seem much more natural, and the poor targets are hardly in a position to complain.

Anker and recently Aukey. And iOrange for cables. The problem is that smaller brands hit the Amazon lottery and get a lot of early 5-star reviews, then swap out their product with one made of cheaper components.

I think for Anker, their brand has become a bit bigger than is gamble-able on a bait and switch, so I'm continuing to use their products.
If we were in a simulation and the simulation would fail to realize its purpose if a sufficiently large number of beings in the simulation became aware of the simulation and changed their behavior, how smart would it be to try to get more and more people interested in the issue and look for "smoking gun" evidence? ;=-)
https://www.teslamotors.com/supercharger

Tesla claims 170 miles after 30-minutes of "super-charging". I think it is fair to say 30-minutes of super-charging is a fair amount. 40-minutes of charging goes from 0% to 80%, while it will take 75 minutes total to go all the way to 100%.

If you argue against these numbers, you're arguing against official Tesla marketing... so you better give me a good citation why supercharging is only 15-minutes.

Maybe the typical supercharging stop is only 15-minutes because that's all the patience people have. In any case, they're not getting a full charge in 15-minutes.
The conditions that allowed the housing bubble to happen were not created overnight.

Hmm, I've always bought Anker and occasionally bought other brands like Mpow, Oldshark (haha) and Aukey which seem like yet another rebrand from the same batch of Shenzhen factories. I know Anker has considerably more Customer Service backend and better packaging but I wonder if their products are engineered any better?
>The DOT isn't the sole operator and user of the roads it builds.

An exit node operator isn't the sole user of the IP address they're assigned either. Yes, they're the only available suspect, but that doesn't change the fact that it's based on outrageously flawed evidence -- it's basically one step up from a hunch, and I don't think it's nearly good enough to be kicking someone's door in.
The simulation hypothesis is, sadly, perhaps the only self-consistent solution to the Fermi Paradox, one that doesn't require very unlikely propositions.

https://www.exratione.com/2015/05/the-cosmological-noocene/

All of the other suggestions require all intelligent life without any exceptions in our past light cone to behave in a consistent way, i.e. fail to build obvious megastructures, fail to come calling, etc, so as to leave everything with the appearance of being natural. The Fermi Paradox is more the Wilderness Paradox in nature. Given that a tiny faction within any sufficiently advanced civilization could on their own generate self-replicated probes that converts the observable universe to computronium, and that some portion of humanity will do that if not stopped, and that we appear in no way to have exceptional origins or be in an unusual region, that really suggests there is something fundamental that we don't yet understand.
The creationism link, I suspect, is that some people associate unanswerable questions like "why is there something rather than nothing" with the preliminaries of some arguments for the existence of a creator.

As a reminder, if you're buying a USB charger or battery, or MicroUSB, Type C, or Lightning cable please buy Anker products.

They are not expensive, but they are the best products you can get your hands on. I own multiple Anker products, and have never discovered anything better than these.

The only non-Anker charger I currently use is the Google Nexus branded Qi charger (plugged into an Anker multiport brick), and the original Chromecast brick plugged into my Chromecast.
I don't know why you wouldn't link directly to the paper, unless you're hoping that Schneier acknowledging its existence lends it some credibility.

> most of the content

Easily refuted: the authors had a spider crawl hidden services, which is laughably stupid. They claimed that there where 5,205 hidden services, of which 1,547 hosted illegal content. Another study [1], one which actually took advantage of network statistics, found the number of hidden services closer to 30,000. Also, well over 90% of Tor traffic is unrelated to any hidden services.

So not most. As far as the analogy is concerned, hidden services would be more like the personal thoughts of the mailman - not the mail he is routing.

If you represent yourself accurately and make the selection process as transparent as possible for women, you will have success on Tinder. This optimizes the problem for women, which seems misplaced given that women already have an abundance of choice. It's designed to whittle down the field for women. For most men, the field is more barren and a different strategy makes more sense: appeal to as many women as possible, get your foot in the door with an actual date, then let your actual interaction determine further outcomes.

> I don't have the experience of being a man on Tinder

I think this is the fatal flaw. I'd value the advice of a man who looks like me who has managed to be successful on Tinder 100x over any woman's. He has faced the same challenges as I, you have not. It's the same as talking to a white person about racism, or trying to discuss gender privilege with a man. The privileged can speculate on the difficulties of the less privileged, but has never felt them. The gulf in life experience has an enormous effect on quality of advice.
