Re: Nah.

Does it? Did Kerkhoff consider the possibility that, by knowing the meyhod, one could ATTACK the method via outside-the-box thinking (like using Shor's Algorithm to attack encryption)?

Re: Nah.

Why? Shouldn't a properly secure system be one where you can know everything about and still can't defeat it? Or is that provably impossible?

"Security always seems to exemplify an invalid syllogism: secure systems are inconvenient, therefore inconvenient systems are secure."

I can see where you're going, but can you provide a solid example of a system that is BOTH highly secure AND dead easy to use. The problem being ease of use tends to eat into that security by becoming a weak link.

No, a proper IT pro makes sure the security can't be bypassed. A gate isn't a proper gate unless (a) it's the ONLY way in or out, or (b) ALL ways in or out have the same level of protection.

Re: A pretty simple concept really:

"Security at the expense of usability, comes at the expense of security."

So what happens when usability DIRECTLY opposes security AND there must be a minimum standard of BOTH for it to be usable? Does that mean practical security cannot be made for this situation?

Re: figuring out

"The possibility for an untrickable machine exists but we haven't figured it out yet."

IS it possible? Or does it become a problem of Decidability, which has been proven to not always be possible (the Halting Problem disproof is an example of a problem of Decidability that's proven to be impossible to solve).

Re: Flashed list of IP addresses.....

They're not. What you're seeing is SVG markup: in this case, it's describing a drawing path (you have the back end of the <path> tag). You'll see commas as well as periods. The numbers are actually floats and seem to be following a pattern of FROM,TO FROM,TO...

Re: Flashed list of IP addresses.....

Those may actually be SVG drawing markup, though it seems weird for the format.

Re: Flashed list of IP addresses.....

I saw it from the outset. It seemed to be associated with an SVG graphics tag. Was also seeing weirdly angled text.

Re: I can see it working tbh

Even with tight data caps? At least locally-owned games only need to pass lean game data around.

Re: OSS isn't Free Software

What if you have no choice and must sink or swim? Remember, you're in the minority and likely have someone over your head.

Re: OSS isn't Free Software

"Yes, that's called "not understanding your problem"."

Oh? If the boss says JFDI and prospects elsewhere are slim? Do you sink or swim?

Re: OSS isn't Free Software

But what happens when the thing you have to do is "EVERYTHING"?

Re: DoH and Privacy

Then how do you propose a way to keep DNS from getting hijacked or even blocked wholesale by hostile people up the chain, given that anything with a known port can AND ACTUALLY HAS BEEN redirected or blocked at the port?

Re: If you have nothing hide, blah, blah, blah

Anytime someone asks that, reply, "Care to give your benefit/identification/Social Security number, then?"

Re: rinse, repeat

"In a few more years quantum computers will make all encryption worthless anyways,"

Shor's Algorithm is useless on NP-hard problems. Several post-quantum systems use lattices, multivariates, and hashes, which can be reduced to NP-hard problems.

Re: Upgrade the root DNS servers

Which the ISPs can still block (as the port is known).

DoH is meant to obfuscate DNS to prevent hostile ISPs and up from blocking DNS for their own nefarious reasons.

Re: Privacy?

"The clients that has DoH functionality will use an internal list of DNS-servers. You may or may not change this list depending on the whim of the developer (adware and malware will probably not allow you to edit or disable this list)."

Think of it this way. It's very hard to intercept Windows X's telemetry system because it uses an internal IP resolution list which means it never needs to use DNS or anything like it to connect. This combined with always using an encrypted connection (for which you don't know the key for the handshake) means the worst you can do is block the connection at the IP level, which has the potential for collateral damage since at least some of the IPs also resolve to the update system.

DoH is another way for apps to achieve the same feat. It's actually always been possible to tunnel DNS through other protocols (meaning malware could do that if it wanted). DoH simply raised awareness of the technique.

I thought ISPs simply intercepted ANY UDP packet with a destination port 53 regardless of IP address and slapped down attempts to get around them as against their ToS.

""The needs of the many outweigh the needs of the few""

Once upon a time, blacks were few versus the many whites. Does the term "tyranny of the majority" ring a bell?

Re: "losing a lot of web functionality"

Has anyone tried referring the project to your appropriate agency for legal compliance with disabled customers (meaning it has to be screenreader-compatible, high-contrast, etc.), possibly with underpowered machines?

Re: "losing a lot of web functionality"

Not always the case. Many use the JS to load the actual content, meaning unless you let it load, all you get is a script and, as aforesaid, 4/5 of FA.

Re: "losing a lot of web functionality"

That's you. For most people, though, breaking scripting breaks the page which they MUST see (Facebook or Bust, Baby), and they outnumber you.

Unless you can rule the world or at least require a license to use the Internet, we're gonna get shouted down every time.

Re: Meh

"I hear all this rhetoric about how we need to bring the Intarwebs to undeveloped nations and how it improves quality of life, but last I checked you can't download antobiotics or clean drinking water."

But ubiquitous communication systems would allow you to make arrangements for the above, especially in situations where time may be crucial. Remember, we're talking areas of the world where telephones (even cellular ones) aren't guaranteed, where you may be lucky to use some kind of semaphore system. It's either this or the (VERY expensive) satellite phone.

Put it this way. One thing that kept remote villages...well, remote...was the lack of communication between them. A lag time of even a day dovetailed into this isolation, which tended to complicate logistics for things that cannot be locally sourced: like water and medicines for some people.

Re: If only...

The trick here is that radio signal quality (for whatever purpose you need) is physically dependent on the frequency. Lower frequencies carry more easily but aren't as dense (they can't hold as much information). Raise the frequency and you trade off the former for the latter. For a satellite mesh like this, there's probably a "sweet spot" frequency that allows it to carry the necessary distance and transfer at a sufficient rate. If that "sweet spot" happens to be the same "sweet spot" radio telescopes use, you're going to end up with a lot of hand-wringing, as radio quiet zones can only be enforced terrestrially: on the ground and in the air, not necessarily in space. And it will be difficult for satellites like this to be able to avoid terrestrial quiet zones in their orbits.

Re: Whoosh!

Not to mention radio telescopes tend to get specifically sited in places with minimal background radiation. It's well-known, for example, that radio silence is enforced near the Green Bank Telescope in West Virginia: to the point you'd be better off Amish or Mennonite living near that thing. It even has a name: The US National Radio Quiet Zone.

Because the network gets used either way, and because of the way the telephone networks ran at the time, I don't think charging back to landlines users (who were just then getting into flat rates on local calls) was an option.

Re: Sony and Fujifilm tape media patents

How about new magnetic substrate materials such as Barium Ferrite (being used now in LTO-7 and up) and perhaps Strontium Ferrite in future?

Re: In Trumpton, it describes a particular style of play in a hockey game

You sometimes hear the adjective "chippy" in America, too. Don't know the exact etymology but it may come from the idiom "chip on his shoulder" (meaning having an unresolved gripe that is angering him). Put a lot of people with angst together and you can create a powder keg situation.

Re: It would be warm for a shorter time

IF you can change them out. Recall one of the big complaints about the trend in phones these days?

Which helps those out in the field HOW?

Re: There's a distinct anti-science bias in many of these comments.

Because the sheer physics and chemistry of fast charging are nigh-universal and thus would apply no matter what the product? Could this be the big thing this report concludes: that there is no free lunch?

Re: It would be warm for a shorter time

Not that much good if an emergency comes up and you unexpectedly need a fully charged phone a few hours early.

Re: Bah humbug

Given the market today, you'll be crossing EVERYTHING from your list, leaving you with NOTV instead.
