Computer Users to Disable Java (Important News)

[vampire]

Thanks, I'm done.

That's one thing we agree on :-)

in some things java is MUCH faster.

Whenever this is the case (which is rare), the C++ program can always be made faster. The reverse is not true of Java. HotSpot is itself written in C++, so no Java program is going to be faster than an optimal C++ program.

JVM can optimize on a fly for a target CPU, C++ cannot (like detecting if the cpu support SSE3/SSE4.1 instructions, so it would optimize better for Intel or AMD cpus). If you deploy a same binary across 100 different x86 cpus, java would optimize better for each of them - Atom, Pentium 4, AMD, etc.

Java in general is faster in memory alloc/dealloc.

Java can also optimize the bytecode on the fly, like inlining of the library functions. Can't really do that with static compiling.

Why it theoretically possible to implement the same in C++, practically its already done in Java out of the box. Yes, Java would lose to optimally written C++ program.. But when you run a C++ program designed for Intel SSE4.1 on a AMD cpu, java will simply optimize for AMD.

I written a lot of C/C++ code, it may be not so bad if you're the only person on the project. But when you have 100 people, Java IS so much better. Strong typing with verbosity helps a lot to understand what the heck 100 people wrote over 5 years.

Computer users are being advised by the U.S. Department of Homeland Security to temporarily disable the Java software on their computers to avoid potential hacking attacks.

I'm ignorant on stuff like this, but deemed it important for the community.

NITE, ALL! (for real this time)

I never run Chrome with Java or other plugins active.

Won't that cause me to not be able to view YouTube videos?

As I've stated in the OP, I haven't a clue.

Youtube vids use flash, not java. Some games use java, but ~95% of computer users will never notice that they've turned off java.

wasn't just a bitcoin site hacked because of Ruby on Rails?

You're comparing a language and a framework. Boo.

Would turning off Java speed up the computer?

Am I? I am somewhat confused since I haven't heard that Java Applets become a language. Last time I checked it was a framework.

Unless it's set up to always run (a possibility, but not, I think, the default option), no. It's usually something invoked when needed.

LOS ANGELES, Calif. - Oracle Corp. said Monday it has released a fix for the flaw in its Java software that raised an alarm from the U.S. Department of Homeland Security last week.

Even after the patch was issued, the federal agency continued to recommend that users disable Java in their Web browsers.

Interesting they only mention disabling it on computers - I'm pretty sure many late model phones use Java too.

I don't think the exploit affects mobile phones, unless i'm wrong

Anyone know if this stuff affects services running on Java, like Freenet?

i think the thing is, you should disable java because someone could write some very dangerous viruses / key logger, and just by visiting a site you could get infected, if you have java enabled just make sure you go to trusted places you should be fine.

can someone correct or confirm this ?

[adamstgBit]

 anyway lets all do it...

i normally never install java, but their was a site i wanted to see that needed java... so i was like fuck it why not... bad move 

[adamstgBit]

Huh? I think you have no idea what you're talking about. Java is one the best languages out there, C# may be slight better designed. But it doesn't run on 100 platforms. And these securities issues, wasn't just a bitcoin site hacked because of Ruby on Rails? And the best online wallet runs on Java??? LOL.

I have always thought Java sucked... Isn't java an interpreted language and this is why it can run anywhere?
my view is that it all sucks balls, everything barely hangs together, the web-code is one half baked idea thrown on top of another, and its only getting more convoluted as time goes on.
Time for evolution to kick in and kill off alot of crap? why do i have a feeling its going to take millions of years  ?

That kind of makes sense, although I guess there are levels of security - untrusted code, and then what it has access to, etc.

As I understand it, Java compilers are pretty efficient these days. Android apps are written in Java apparently - but don't get Java the language confused with Java the compatible-compilers - Android apps don't run on Oracle's Java engine. Oracle seem to be the problem more than "Java" in this case.

Well that's a wrong view. Java is fast, well aside from ASM/C/C++ it kills anything in performance Ruby, Python, PHP, Perl....

The applet API is outdated. You cant really write a secure sandbox in the environment that isn't designed from scratch for one. JVM wasn't designed to be secure as a linux kernel, and java applets are probably the only case of the java app being sandboxed. Android apps are sandboxed via an *nix kernel.


Oracle VM isn't the only one around.. Linux comes with an open source by default.

You can disable Java in your browser (which this thread is about), this will not affect stand-alone applications using Java, like Freenet or Freemind.
