Re:Big shoutout to Tridge and the whole Samba team
on
Samba 4 Enters Beta
·
· Score: 4, Interesting
MS didn't just open up their protocol, they invited the SAMBA team, had 2 SMB/Network lead engineers to answer their questions, and gave them a full Linux+Windows environment to play around and test different things.
Netflix is also at the front of the internet pack with IPv6 roll-out, and FreeBSD
plays an essential part of that. We've been working hard on stabilizing the
FreeBSD IPv6 stack for production-level traffic
But but but.......BSDL gives no incentive to give back!
If you look at the complaints of Comcast customers, it's that "the internet is slow and I'm getting packetloss" during peak and they don't use P2P or anything hoggish. But you will notice that these people also mention they live in high density areas like large apartment complexes. You will also notice other people claim to be using Comcast in the same city and don't have any issues at all.
During the whole L3 vs Comcast issue, L3 requested 270Gb of additional peering bandwidth. Remember, L3 is a tier1 back-bone. This means Comcast and send data to L3 and L3 will route that data to anywhere in the world. Being that Comcast and L3 have a peering agreement, it effectively means Comcast gets its internet for FREE. When L3 comes to you and offers you 270Gb of free bandwidth and you turn it down, that means you don't have an issue at your trunk. That's enough bandwidth for almost 70k 4Mb data streams
If Comcast doesn't have have congestion at their trunk, then the only other place is their last mile or their middle mile(or whatever it's called). When you own your own network or lease fiber, upgrading the "middle mile" is almost free. The logical conclusion is that the last mile is the bottle-neck.
There is hope around the corner, Netmap claims to share no locks among established TCP connections. It also claims to scale extremely well with many cores. A 950mhz single core CPU can saturate a 10Gb interface. It can also attach a given connection a to a given core and have the NIC forward the data to the L2 cache so it's ready to be processed. It is also capable of handling send/receive events on different cores for the same connection.
Should make for some fast routers. It is being ported to Linux and is in FreeBSD 10 Head.
Modern OS's tend to use DPC(deferred procedure calls, or something) in place of many interrupts. This keeps the CPU from cache-thrashing. Not great for firewalls, but great for user-mode programs.
Don't even care about seconds. There is a noticeable difference between being a block away and in the same building. When you're talking about sub-microsecond difference a noticeable difference, then it's just getting insane.
Not as much for "ideological purity" as for compatibility. Linux is currently growing in the 3D support area and will have much more growing pains if drivers are closed. An example of that is Wayland. A new way of communication between the GPU and kernel needs opensource drivers to test. I'm not sdaying this is happening now or will happen really soon, but it will happen eventually. As tech progresses, APIs need to change. The GPU API is getting old and new exciting GPU tech is coming out soon(tm).
Linux has a fairly well-funded user-base and a low entry point being a free OS. While I do agree that many of the current games may never get ported, I can see an up-swing in Linux only or multi-platform games in the future. I would be willing to repurchase many indie games if they made a new Linux version.
Whomever gets the first well supported opensource drivers for their mid-grade GPU first, stands to win the affections of the Linux community. AMD vs nVidia. Intel could possibly be a contender if they had a mid-grade GPU to offer.
Hell yeah. With Steam on Linux, it's the beginning of the end of me having to boot Windows. I hope it plays well with BSD. I've been Windows only for years(would have Linux if I had more than 1 computer). Finally.
In 2001-2006 we spent enough on war to cover they person in the USA with college education and health-insurance for 10 years. Don't quote budget info, because war-costs aren't in the budget, only general military spending is.
"Here's a better idea. How about we don't spend so god damn much?" - There is a reason anon said to reduce war spending.
I just looked up the price the state non-profit co-op offers to schools and it's ~$850/m for 1Gb.
I don't think the issue is lots of students using a bit of bandwidth all of the time, but a teacher in a class room consuming a large amount of real-time bi-directional streaming data during a class. Think of a guest speaker doing a remote Q&A with several classrooms from around the country, all HD streams so the kids don't get distracted from the bad quality.
Or even think of remote teaching where a school doesn't offer a class, but another school in the region does. If kids/teacher can't make out faces or a teacher can't read something, the quality of the experience will be reduced to worthlessness.
There is a lot of exciting tech coming out to help connect teachers and classrooms in real-time across the nation, but we need the bandwidth to handle it.
The point is he is perfectly happy with low quality video streams. If you take a 320p video stream, stretch it to a projector/etc, you're going to have a hard time engaging kids with a blurry mess. If the kids can't make out faces or read text, you might as well have an audio stream.
Cheap relative to under-educated children caused by a lack of decent network connections. The modern school-room will allow for real-time video conferencing and video-streaming. you lack of vision astounds me. Humanity doesn't progress out of need, but out of want. Eventually the want turns into a need, but we're all the better for it. 200 year ago, people didn't need the internet/phones/etc. If you suddenly removed the internet and all phones/etc, how would society cope? Not very well I predict.
Heck, by your logic, we don't even need society either. What is the bare essentials for life anyway? Probably none of the luxuries society provides.
I'm saying your argument only applies to the minority and does not explain why the majority, whom are in cities, may not get access to decent internet. I guess I'm saying your argument is only wrong most of the time. Don't use corner cases and talk like it's common.
Most schools/etc don't need the enterprise quality of an OC-24, cheaper fiber technologies exist. My state offers 1Gb dedicated connections for $10k/year to schools, where the fiber infrastructure exists. That's non-profit at-cost pricing.
"I watch hulu and youtube video with only 0.3 Mbit/s" - My bandwidth meter shows about 1MB(8Mb)/s sustained for HD YouTube. You must watch the blurry crap.
Over here, $250/month gets your a dedicated 45Mb/s circuit if you're a school/library/hospital. Most of the cost is in the circuit. Once fiber starts going live state wide over the next 5-10 years, I expect 1Gb being dirt cheap.
I found a PDF about that 1Gb/s/user. It is actually 100Mb/s/user internet side and 1Gb/s/user WAN side. So a highly connected WAN and a decent internet connection.
This is the exact opposite of how normal people describe powerful languages. The most powerful languages let you get the most work done while fighting your language the least.
When a language is doing lots of work for you, you'd better know what kind of work it's doing.

The actual problem is Comcast's congestion is in the last mile. No amount of ISP caching will reduce last-mile congestion.
"me still a virgin" At least you don't have unusual burning/itching feelings in the nether regions.

1.5 Mbit/s is more than sufficient to carry a 240p
Let me know when you mention 720p

And 90% of the USA lives within a densely populated city. Get a clue.
This is why AT&T can claim it covers 90% of the USA while only covering 10% of the land.

I found a quote "1,000Mbps service for about $10,000 annually". Sounds like a good price to me. MMmmmm.. whole sales costs.

"security has no ROI."
Security has a best case of no return and a worst case of "you lose everything".
Preventative doctor visits also have no ROI, yet they keep saving money by saving lives.
Ask them why they think banks "waste" money on security.
