  1. Re:Interesting on Latest Java Update Broken; Two New Sandbox Bypass Flaws Found · · Score: 1

    Yes, in some ways I agree it is a "smear campaign", but I don't think it's an unjustified one. When a product has had vulns this serious this many times, yet maintains huge deployment due to market dominance and user lock-in, a huge smear campaign is needed to destroy it. This was the case in the past with products like BIND, Sendmail, WU-FTPD, IIS, IE, etc. and Java is just the latest necessary target.

  3. Re:Take THAT on GNU C Library 2.17 Announced, Includes Support For 64-bit ARM · · Score: 5, Interesting

    In fairness, this is complicated a lot by two issues:

    1. Many of the optimizations that help things like memcpy, memcmp, etc. are utterly wrong and backwards in any loop that actually DOES SOMETHING in its body; they only end up being optimal in the degenerate case where everything but the load and store is loop overhead and the optimal result is achieved by eliminating overhead. And on some CPU models such as most modern 32-bit x86's and some 64-bit ones, the optimal result is actually attained with a special instruction that's not usable in general for more complex loops (i.e. "rep movsb"). Factors like these make optimizing these specific functions in the compiler a task that's largely separate from general-case optimization, and when the main target libc is already providing the asm anyway, there's little demand/motivation to get the compiler to do something that won't even be used.

    2. Distros want a binary library that can run optimally on all variants of a particular instruction set architecture. Relying on the compiler to optimize functions for which the optimal variant is highly cpu model specific would only give a binary that runs optimally on one model, unless a lot of logic is added to the build system to rebuild the same source file with different optimizations. This is not prohibitively difficult, but it's also not easy, and it's not worthwhile when the compiler can't even deliver the desired optimization quality yet.

    Overall I agree that machine-specific asm in glibc (and elsewhere) is a disease that results in machine-specific bugs and maintenance hell, but when there are people demanding the performance and pushing benchmark-centric agendas, it's hard to fight it...

    Or just have the good sense to purchase business-class service. I really doubt they do this crap to their business class. Most of the time, business class is only marginally more expensive than residential, and has none of the restrictions such as no-server rules or other crippling of the connection. Sometimes it's even the SAME price; this seems very common in the case of DSL but I'm not sure about cable. Often you can get one or more static ips at little cost that way, too.

    There are already laws addressing that type of voter fraud. That's the whole point of this article, in case you missed it. And it's why it doesn't happen much. The voter ID laws attempt to address a completely different type of voter fraud that DOES NOT HAPPEN in any statistically significant amount, in ways that disenfranchise huge (statistically significant) numbers of voters, mostly low-income and minority voters.

  16. Re:This is actually dead end... on Kim Dotcom's Next Venture: Free Broadband To New Zealand · · Score: 1

    Your argument only appeals to selfish faux-libertarian types who don't care about anything but not paying taxes. Some of us are happy to see litigation against authorities who commit injustices in our names, even if it means financial losses for us too. That part of it is what we get for letting them get into power. Ideally, the system would be reformed so that the majority of the liability is on the parties (industry, lobbyists, etc.) who convinced those authorities to perform illegal acts in our name, but it's everybody's responsibility to take part in making that happen.

    Your individual decision to adblock or not makes no financial consequence for sites you like. Only the prevailing collective behavior affects their bottom line. Simply keep up the adblock and send them a donation if you want to do something much easier and less-costly to yourself (in terms of time and effort and privacy) than trying to support their ads. As for the perspective of sites, those whose users are savvy enough that a significant portion use adblock should take concrete steps to make it easy and safe for their users to whitelist them, or offer other easy ways to support them (like donations, premium/supporter accounts, merch stores, etc.).
