Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

Bengie Re:Oe noes! A compiler bug! (519 comments)

GCC is the OpenSSL of compilers. I'm amazed how many people don't appreciate design and quality. This is why Linus and OpenBSD love to yell at people. They'd rather not have to deal with stupid, so they scare them away.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

Bengie Re:Surprise, surprise... (519 comments)

You mean when Tridgdell violated the EULA and illegally accessed the Bitkeeper service with the intent to reverse engineer, when Linus said not to? Tridgdell claims to have done it to help the Linux project by gaining access to meta data not available to the free version of the client, but Linus agreed to the EULA and had access to this information already. Because of Tridgdell's actions, Linus had a large mess to clean up.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

Bengie Re:I know you're trying to be funny, but... (519 comments)

Linus only goes off the rails like this for nothing but complete and utter unforgivable incompetence. They deserve exactly what he said. He calls it like it is, and I respect him for that. No beating around the bush when people are doing the most horrible of "mistakes".

Soccer Superstar Plays With Very Low Brain Activity

Bengie Re:Put it another way... (144 comments)

I wonder if some people are just born with strong interests, so they just have more time consumed with something that caused them to be better.

Comcast Carrying 1Tbit/s of IPv6 Internet Traffic

Bengie Re:Advantages? (143 comments)

Install OpenBSD on a computer not behind a firewall and see if it gets hacked. I think they've had 2 remote security vulnerabilities in the past forever.

Bengie Re:Advantages? (143 comments)

No, I expect users who want to run services that listen on ports (which makes them not "average!") to know about those things.

You mean like the "server-less" P2P console games that elect the host from one of the current people in game?

Comcast Carrying 1Tbit/s of IPv6 Internet Traffic

Bengie Re:Advantages? (143 comments)

Unless you want to reinvent uPnP for v6

What are you talking about? PFSense supports IPv6 uPnP with the base install. Just enable uPnP service and it will allow uPnP to punch holes in the firewall for the requesting IPv6 address. Worked just fine with my Windows box and Torrent. It was quite turn-key. Enable service, done.

Bengie Re:Advantages? (143 comments)

Why would they be able to discern anything about your internet network without a NAT. You just saying that indicated you don't know what you're talking about or you're trolling.

Bengie Re:Advantages? (143 comments)

Except NAT has no official implementation, so many implementations have many different security bugs to be exploited. Firewalls are easy to test, NAT implementations, not so much.

Black Holes Not Black After All, Theorize Physicists

Bengie Re:Wait (224 comments)

If, however, time slows as it approached the blackhole and the particle never actually crossed the event horizon

Can someone please explain this. It seems to be accepted that not only does the object's time slows down as it approaches the event horizon, but it's velocity does also. I don't get that. If an object is moving away from me at 0.9999c, I could expect is to actually be moving away from me at that speed, not slowing down relative to me. If from my perspective an object has stopped moving, then it is no longer moving relative to me and its time should be pretty much the same to my reference.

I seem to be missing something. I assume it has to do with gravitational fields instead of "proper" velocity.

Black Holes Not Black After All, Theorize Physicists

Bengie Re:What about existing evidence? (224 comments)

Another orthogonal explanation.

Any light emitted from the "black hole" itself could also be dwarfed by the noise of all the other em coming from the accretion disk, making it nearly impossible to detected remotely.

Black Holes Not Black After All, Theorize Physicists

Bengie Re:Why is information movement a paradox? (224 comments)

Time must be reversible. Once information falls into a blackhole, there is no way to reverse time and get the same information out because the information becomes ambiguous in something that in infinitely dense.

For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

Bengie Re:well rounded cool but not at today's price leve (171 comments)

Why are you comparing "PE" in a 4 year degree to a fitness club? It's a full on class where you spend most of your time learning in a lecture hall. As for "hands on" skills, so many people that learn these "skills", but only know exactly what they were taught and nothing more. Those "hands on" skills have expiration dates when the technology changes. If you really want to learn something useful, learn they theory behind those skills. While theory and "hands on" skills can both be learned, most places tend to focus on one or the other and theory is much more important.

'Just Let Me Code!'

Bengie Re:Go work for a bigger company (367 comments)

He doesn't want to use frameworks, he wants to reinvent the wheel, poorly. This is a mix of sarcasm and opinion.

'Just Let Me Code!'

Bengie Re: Just let me do brain surgery! (367 comments)

I think what he meant is if brain surgery was as bureaucratic as many projects, it would take too long and would be a botched job almost every time. But yes, lots of pre-op stuff to do.

Verizon Boosts FiOS Uploads To Match Downloads

Bengie Re:Thank Google, not Verizon (233 comments)

I personally don't see the point of more than using 200watts at home. Just enough for two light bulbs.

Wait, if you have enough power to the house, you can have ovens, refrigerators, and air conditioning units?! Wow, who would have thought about the new awesome ideas 100 years ago when power was limited?

Unless you're God and can see the future, stop acting like you know that there is absolutely no benefit to improving technology.

Verizon Boosts FiOS Uploads To Match Downloads

Bengie Re:Symmetrical? (233 comments)

80/20 rule would most definitely apply on average. When reading about Netflix' caching servers, something like 10% of the data represents about 70% of the hits.

Netflix' SSD servers only have about 10TB of storage, and they have about a 70% hit rate, while the rust-bucket servers have 100TB of storage and have about an 80%-90% hit rate. Their entire catalog is about 1PB.

P2P would work best for flash-mobs. It would reduce the number of cache servers they need deployed in other ISPs.

Verizon Boosts FiOS Uploads To Match Downloads

Bengie Re:Symmetrical? (233 comments)

The 80/20 rule is a great rule.

Assuming decent buffering, you can start streaming the video live at the beginning, and the P2P can start buffering the later part of the video. Just use the normal servers for starting the buffer, but then use P2P to populate as much buffer as you can. I'm sure the 80/20 rule would apply.

Verizon Boosts FiOS Uploads To Match Downloads

Bengie Re:What about (233 comments)

So it makes little sense to have asymmetric fiber service other than for marketing purposes.

Most fiber deployments use GPON, which shares bandwidth. High speed sending optics are more expensive than high speed receiving optics. Most ONTs can receive up to 2.5gb/s, but can only send 1.25gb/s.. If using Active Ethernet, then it'll be completely symmetrical, and you'll have 1gb up/down. But in GPON mode, you have 2.5 down and 1.25 up.

Google Fiber uses WDM-GPON, which has 32 lamdas of 1.25gb/1.25gb, so it's all symmetrical, but they were an early adopter and used the draft version.

The other question that comes up. Since the fiber is already dedicated, why use GPON? Well, you get higher port densities and less power consumption, but quite a bit. There is a good benefit of having 32 customers per port instead of one customer per port.

Resolving IP to MAC address across a router

Bengie Bengie writes  |  more than 6 years ago

Bengie (1121981) writes "From what I know about networks, you can't find out the MAC of an IP across a router. At some point I stumbled across a program that does just this. The only google hits I get talk about Netbios. Being able to do this would help out IT dept because our back-up registration page pulls MAC info from our DHCP server, but the DHCP database only syncs with our back-up database every 24 hours. If we build a new computer to replace an old one, our registration page can't get the new MAC for the Wake-on-LAN info until 24 hours later. We could use netbios if we had to, but that's kind of shady and won't work for our Mac computers since they don't have netbios. Is there a way of resolving the MAC of an IP across routers?"
