I can handle the sun outside, but what gets me is over-cast. I think the dilation of my eye is still controlled by regular light, so mild overcast makes my eyes ache, which seems to be highly correlated with the UV factor. High UV and bright outside doesn't bother me much, but high UV and overcast hurts.
ZFS is open source. The only real issue is the stick up GPL's ass about *having* to share everything.
GPL is a bit too idealistic for my taste. I'm not saying it's bad, but extreme of any sort can't ever be "great". Personally, I like the BSD license. I would compare GPL to Steam's DRM. Non-obtrusive, but it's there. Not "truly" free.
"Nice note on btrfs, no fsck for it sucks" ZFS has set the standard for an enterprise grade FS. If you need fsck, you're doing it wrong. Your FS should never be in an unstable state.
BTW, I think Linux/GNU is great, I just think it could be better.....slightly...
What I don't get is why they use "miles". "Billions" is already such a large number that I cannot relate to it, might as well use a "proper" measurement.
"When I taught college algebra, several students bemoaned the fact that I would not allow the use of calculators on the exams."
Depends if you're trying to test how well a student can do math in their head or how well they can "apply" math.
I can't do math in my head, I reverse numbers all the time. My math teachers thought I was a dunce. Once I hit algebra and the problems assumed you had a calculator, so they had complicated problems, I was solving them faster than the teacher.
I can problem solve and follow logic extremely well, but I can't do math in my head. I can design a scalable multi-threaded+async system with little to no issue, easy stuff. Toss some math at me and no calculator, and you'll think I have brain damage.
This is how it works. A relatively small portion of the population donates money to some "artists". They create something new which also creates jobs for those artists. So now the economy has a few more jobs. Those artists spend more money, which creates more jobs. But now we not only have more jobs, but we also have new "art".
Society is now better off because it has more art. That art sells, which in-turn brings in even more money to the artists, which creates more jobs.
The more money moves, the more value it has. Those people donating are getting something back, they are getting a stronger economy and more art.
You have to look beyond your nose to see the true value.
It's Windows only if they make the $400k. Excess money they will use to first port to OSX, then Andriod/Linux. They arent just going to pocket the extra, they will feed it back into the game. How much they need before it's worth porting to Linux? No idea, but they're currently 3x their initial goal, and only 2 days into their 33 day goal.
You can always wait for the Linux version and buy it or you can speak with your wallet and help.
It's just a matter of trust. If you want a great reward, you must first take great risk. Even if I didn't make any money off of it, a new unique game released would be reward enough for me.
Most OSs never map 0 to userspace, so any null reference will just cause an access fault.
At least using null as a reference/point means you don't need to actually check said memory location to see if it's "null". You just look at the pointer/reference and said "hey, it's null, that means it's not referencing anything." compared to "The point says 0xDEADBEEF, lets go there.. twiddle thumbs while loading the memory location... lets check to see if the "null" boolean value for this object is set... ohh, it's "null" so lets ignore it"
Great, now you need extra memory loads and you're doing the same F'n check. You gain nothing, but you lose something.
1) QoS is your friend. Most OSs and routers support QoS for VoIP out of the box. 2) Bursting is good for networks when having very small transfers(like web pages) by creating smaller transfer windows. Overall packetloss is reduced, along with jitter.
If you really want to see jitter and packetloss, create a single bottleneck where lots of TCP connections are communicating across. You get this grow and collapse pattern that is either over-saturating or under-saturating the network.
The current issues are more of "Scaling" issues. While latency is relatively constant because of physics, bandwidth keeps increasing. Keeping those fat pipes fed requires larger and larger buffers.
Ideally, fewer TCP connections should result in fewer dropped packets. I'm not sure how that interacts with SYDY's bursty start up, but if connections are going up and down a lot, then that burst shouldn't happen often.
1) You're talking about DOS via running out of memory 2) You will run out of bandwidth well before you hit this limit
8GB stick of ecc 1333 low voltage memory from a namebrand, ~$125. Dropping 16GB of memory on a a web server is nothing. 16,777,216KB buffering 128k per connection is 131k connections. If your single web server has 131k active connections, you have other problems to worry about.
Like I said, IO is your bottleneck. You will be DoS'd from all the data you're sending.
A properly configured web server behind a properly configured firewall all running on modern hardware, will run out of WAN bandwidth before the DoS causes other parts to crash under load./. effect is about the only real DoS.
Connections are easy to handle if you async all your IO. Maybe current proxies need to become more modern and not spawn a thread for each connection. You could also have a proxy per subnet to help load balance all 3000 users. nginx style forward proxy, ftw!
Another neat feature of proxies is they can multiplex requests from several client over a single HTTP1.1 connection. Help reduce state bloat on your edge firewall from all of those connections going through. Lots of TCP connections can have a negative interaction, so this can help local, external, and web server side performance.

US Cellular seems to calculate your months bill based on the service you're subscribed for at the end of the billing cycle. Changing your plan mid-cycle applies your "new plan" retroactively to the beginning of current cycle.
I wish they just had an option to "auto select" the cheapest plan for a given month and bill you accordingly.
I've been scouring the internet for info on FreeBSD as I am interested in making a ZFS file server. I have never come across anything negative about it, other than "not bleeding edge". The words I have found most often are "Secure", "Stable", "Scalable" and "Friendly". Benchmarks show it close enough to Linux for average cases and better than Linux for "holy crap the server is getting hammered!" cases.
"And no, ZFS is not a sufficient reason to go through all that pain.": Depends on what you're trying to do. As a server, I hear it's much easier to manage. Everything is well documented and you don't get a "distro", you get a full system. Based on my readings, ZFS is f'n awesome. Not to mention my cousin swears by it for this 10,000+ HDs in his datacenter.
The only real issue BSD has is a limited supported hardware list. What it does support, it does every well, except a few corner cases. Since ATI has an MIT licensed open source driver and they've hired on a lot of Linux devels/engineers, I expect ATI support to get increasingly better over the next 5 years with BSD gaining from the Linux work.
"BSD developers want to keep the system exactly the way it was 30 years ago": They just have a stricter standard for what get's included. From what I've read, "beta" for BSD is like "stable" for Linux. It seems like nothing makes it into the system unless it's ready for the real-world, and it's not marked "stable" until it's been hardened. It even puts Debian stable to shame. When a new hardware feature comes out, they seem to jump on board for Rev3 instead of Rev1. This means they're constantly behind bleeding edge, but that's becoming less and less an issue with current computing power and abstract designs/frameworks.
It's a different product for a different audience, but the audiences are starting to converge because of how technology is moving. Linux and BSD is apples and oranges. Both are great in their own way.
If you're in space, you also get to enjoy flashes of light even with your eyes closed because of radiation interacting with your eye. I wonder if they stayed outside their protective room, if they would see a disco ball of light from the solar onslaught.
Where I live, we don't have a "minimum fee" clause, we just have the connection service itemized separate of the usage. In my case, you pay *after* you use, not before.
What I'm really curious about is the new radio link they use works. They don't even send out people any more. They have an antenna hooked up near the gas and water meters. It does not plug into anything. Just a long wire anchored to a small black box 1"x1"x1/4" that secures to the pipes. They use these for real-time data so they can optimize their delivery network, and of course billing.
Do they send power through the pipes? How do they pick up the signal out of my basement? I have no idea how these things work.

Assuming what Netflix pays for GB/$, $40k will buy you about 1.3PB of data. That is A LOT of patch data.

I hate that "bloom". My eyes ache from it. Black lights in my field of view hurts my eyes.
Is that what they mean be the world ending? The beginning of the end of MS is 2012, when Wayland/etc gets released.
What will the future bring us? Will MS leave eventually leave the OS arena and make libraries and UIs for Linux/BSD/etc?
All I know is I live in exciting times and I can't wait to see what the next 10 years brings as hardware and driver interfaces become standardized.

"Compare how much operating systems advanced between 1970 and 1979 compared to how much operating systems changed between 2000 and 2010."
2000 to 2010, many OSes gained *much* better scaling, lots of virtualization, and better power efficiency to name a few.
If you think OS design has stagnated, you're not reading enough. There is A LOT going on, especially with scaling.
"tell them if they cheat they'll get zero."
There's already rules against cheating in college. Great way to get expelled.

It's "harder" to do with for short lived connections, but yes, the same issue exists.

"Its a secret plot by Apple to fix the lag in IOS 5 Safari by getting Google to find a way to speed up web page loads to cover it up!"
nginx tweak guides recommend forcing Safari to HTTP1.0 because of a horrible bug in their 1.1 implementation. I'm sure that doesn't help.

There were some huge changes in 8.x to stabilize upgrades/etc. Moving forward, upgrades sound to be quite easy.
