The pirate scene isn't what it used to be when it comes to adopting new technology. In the past the scene would adopt whatever codec gave the highest compression efficiency with little regard for anything else. You could see this in th

Not by a long shot either. The current stable version of Chrome (72) came with 58 security fixes, including a dozen UAFs, albeit several of those are in third party dependencies. https://chromereleases.googleblog.com/2019&#x

I was speaking more in a hypothetical sense, but you're right. The DNS as currently implemented is sufficiently broken so as to preclude securing it.

As long as DV certs exist the registrars are trusted anyways[0]. DNSSEC + DANE, for all its faults, would at least reduce the set of trusted actors by cutting CAs out of the chain. [0] Yes there's CT to help catch dishonest registrars,

This attack vector is not something DNSSEC was ever intended to defend against, so why would it be mentioned? Once the registrar account associated with a domain is pwned the attacker can do pretty much anything they want with it, including

The FED certainly still remembers the mortgage mess, considering they still hold some $1.6 trillion in mortgage backed securities on their books. One wonders what they will do when the next debt crisis hits. Will they take on another trilli

This is the sort of thing I was talking about when I mentioned negative externalities elsewhere in this thread. NAT is nice if you want to do things like that, but those sorts of tricks create big problems for people like me. Being behind N

As someone who works on P2P applications, if all I had to do was use PCP to open a pinhole in a firewall it would still be a big improvement over dealing with NAT. For one thing lack of NAT makes it much easier to deal with multi-homed syst

You're right some some applications are more effected than others. It sounds like you were dealing with business customers, "asked people to...forward a port on their NAT" is not a viable strategy when dealing with consumers.

Some users have asked their ISP for IPv6, but they are in the extreme minority. The average user is obviously never going to ask for IPv6 because they don't know what it is. Really the hope is that users would complain killer app x d

The thing about NAT that for network operators it is a negative externality. For them it often simplifies their job. They do not feel the searing pain it inflicts on network application developers. It's hard to come up with a carrot to

What we really need is a killer app that requires end-to-end connectivity. Users have little reason to care about IPv6 right now because the existing ecosystem of services has evolved around the constraints of NAT. As IPv6 deployment expand

It's easy to make an Intel CPU stay within the limits of a particular power supply and cooling system by setting PL1 and PL2 appropriately. It's a Heisenberg's uncertainty sort of situation. You can fix frequency and get vari

Knowing the peak power dissipation at max turbo frequency wouldn't be quite as informative as you might think. The problem is power consumption varies widely depending on the workload. Presumably Intel would be expected to report power

The difference between input power and thermal output of a CPU is negligible. A tiny amount of electricity is used for external signalling, the rest gets converted to heat. So in practice TDP can be treated as a limit on input power. In fac

Like I said, the Anandtech article has a lot of inaccurate information in it. Unfortunately the quality of tech journalism has taken a dive the last few years as most of the good writers have been hired away by the very tech companies they

Balanced inbound/outbound traffic only matters for transit networks. That is, networks which are neither the source nor destination of the traffic they carry. Nobody expects a residential ISP or a CDN to have balanced flows at part of

That page is embarrassingly wrong about how power management works in Intel CPUs. By default Intel CPUs will not allow their rolling average power consumption over a period of ~1 minute to exceed the specified TDP (95 W in this case). Once

A bunch of Pis networked together is sufficiently far removed from a real HPC cluster that you could probably create a more realistic simulator without too much trouble.

Starting a company doesn't necessarily require a large amount of capital. Think self-employed people creating LLCs. Such single member companies are not at all uncommon and, just like with any type of business, most of them fail. So if

So you think only the rich should be allowed to start their own company too? Quitting a job without having another one lined up is also pretty risky. This argument taken to its logical conclusion leads to serfdom. You might even say it&#x27

Phoronix is, once again, wrong. Skylake does not support the SHA instructions. The only currently shipping x86 CPUs which support them are Intel Goldmont (Atom) and AMD Zen (Ryzen, Threadripper). Mainstream support for SHA in Intel CPUs wil

I wonder, how much research is there these days that doesn't get at least some money from a government agency? As a casual observer it certainly seems like the government throws so much money around that they have long since crowded ou

The hosting cost for things like Facebook and Twitter are a pittance compared to the cost of employing all of the engineers/designers/etc who enhance and maintain those services. That IMO is the biggest economic challenge facing

Ryzen is known to be memory constrained even with much faster memory than he used. It is completely predicable that he found his CPU to be severely starved for memory bandwidth thus enabling him to reduce operating frequency without penalty

The re-ordering you were seeing may have been due to a lack of sequence points between the ordered operations. For example: If you have two 32 bit registers which correspond to a single 64 bit value and which must be read in a specific orde

But in most people's workflows there is something special about the central server: it is the source of truth about the state of public branches. That is why losing the central server is so disruptive. It means you have to re-establi
