I can do 18-20 in the flats on my road bike with just me providing the power. If that is all the power that the electric kit will produce - why bother. Just get into shape and do it yourself.
Note that this story is obnoxiously spanning 6 pages. For a publication named "Network World" you'd think they'd know better.
Do you think they make their money by letting you read the content of the article, or by putting ads on the screen with them. I really wonder if people are so simpleminded as to think companies do things for charity - use bandwidth, create content, provide services, etc.
Of course it spans 6 pages. That way if you like the article - they get 6 ad views. Perfect for them
There is no problem with deciding on GPLv2 vs. GPLv3. You are all ready developing for GPLv3. After all, it is a future revision of GPL, so there is a default licence upgrade provision in GPLv2
I'd prefer to invest in layer3 switching before some over-spec'd router;-)
So answer me this one... What is the difference between a "Layer 3 switch" and a "Router".
No seriously - I actually have been trying to find out...
Wish I had replied earlier so I could see about 10 different replys giving 12 different answers
Just like Slashdot - a bunch of links to articles of various quality - with some supporting editorial text that doesn't explain the bias in the links...
Strange - why would you expect companies to step down from decent DSL speeds to T1 rates. I assume small companies stay on DSL/Cable for the download rates (host their web server somewhere else - what do you need upload speeds for anyway), then move up to OC12/48 rates (or multiple OC3) when there are enough employees to justify the need for the upload rates these speeds provide - or the reliability of multi homing the network. Again this trade off happens somewhere north of 100 tech workers, or multiple branch offices needing to share resources (SVN/CVS/???) for development
I defy you to be able to route 4 Gbit interfaces through a single low end PC, heck - even a mid range server with a few PCI-X interfaces... Don't think you can do it.
Anyone have any Packets Per Second (PPS) rates for a generic PC ? It used to only be in the 10 Mbit/sec range - for 4 interfaces... I am sure it is quite a bit faster today with decent hardware
But then again for SMB - you don't need 100 MBit routing - many of your internal clients are slamming into your sub 10 Mbit internet connection anyway (that is probably further BW limited by the cable/phone company). Now for true enterprise - you really do need switching/routing at the ASIC level - real switching fabrics (not a glorified PCI bus) in the hardware etc. to handle the multiple GBit links, multiple OC12/OC48 connections to the world, etc.
This is where Cisco shines and I don't see "software only solutions" coming anywhere close
No, just the local dealerships in Lake Tahoe, Las Vegas, and Grants Pass would be paying Lockyear a HUGE campaign contribution for increasing their business as californians are required to cross state borders to buy new vehicles.
The local dealerships of course would loose all of their inventory allocations and be forced to sell only used cars. Would be funny to watch - I would love to see how long that one lasted.
WTF do ignorant people like you have against employing Americans? The fact that someone would pay $800,000 for a 1200 square foot 50 year old home in California leads me to believe that you guys are a bunch of dumbasses.
Nothing wrong with employing americans. Just have no idea why companies would put and maintain roots in the silicon valley. Employee turnover is significantly higher, saleries are significantly higher (They don't joke about bay area saleries... they mean it), and lets not talk about cost of living etc..
All of that said - it is much cheaper to hire in places like Iowa, but the talent pool (or the ocean for that matter) isn't there.
Yeah - bay area, I'd see an Intern easily going for 4K a month - then 2K a month for random benefits, cost of office space, etc.
Now if you are in Iowa - I would expect that to drop in at least 1/2, but then who would want to outsource to Iowa when you can go all the way to Bangalore and get it for 1/4 of that.

I always liked this story More Magic. A wonderful story about a switch that wasn't connected to anything, but when you switched it off of the More Magic position into the Magic position, the computer crashed.
Watch what happens when you start pushing a 5-8 Gbit/sec stream through your dual socket server. That will take a rather large bite out of CPU utilization. I have measured CPU utilization on a real OS above 50% running 9 1 Gbit/sec streams through a 10 gig NIC (not TOE) and watched it drop to about 25% with TOE. Those damned copies get you every time
1. First interesting thing is you are actually voting on a slate of people to vote in the college. There is VERY little that can be done if an elector doesn't vote the way they are "supposed" too. There are many cases of faithless electors sending protest votes to other candidates - usually it doesn't matter. There were talks about 1 or more faithless electors in 2000, it just doesn't happen.
2. The elctorial college is all about limiting the effect of fraud on the US. Lets say instead of a few dicey votes in Florida - you have the ability to have the dead rise to vote in Chicago. Well, the damage that the chicago precinct can do to the national election is limited by the number of electorial votes in Illinois. So without the college - there would be a huge increase in vote fraud in places that you can control (basically - Illinois tends to vote democrat anyway, why have the democrats that run the election polls in chicago rig for more democrats to vote if it isn't going to do any good)
3. It balances the nation... Want to see a candidate not leave Florida, Texas, California, New York, and Illinios ??? Just use this system. Why even bother to campaign in Iowa - it just doesn't matter as a state population wise.
4. It really doesn't make a difference anyway. In about 200 years (50+ elections) there have been only 2 times the winner of the popular vote hadn't won in the electorial college that I am aware of... That is a 4% "failure" rate. Overall it just doesn't matter to fix 4% to open the country up to the problems above.
5. Frankly, despite what people say... Who is president for 4 years really just doesn't matter. The president has rather limited power. You want to complain about the spending explotion in this country (the deficit) talk to congress. You want to talk about the war in Iraq - talk to congress. You want to complain about most things - talk to congress. If that doesn't work - vote the idiot out in 4 years.
Doesn't mean you have to define it with money. Worked for a startup that the CEO would pay for lunch on a quite regular bassis. His comment was that the lunch was to guarantee attendance - so he (or anyone else) could say things that everyone in the company needed to know.
Cost to Me - 0
Time I spent - 1 hour
So the cost was 1 hour of my time that I used to pay for lunch.
Cost to the CEO - 15ish * #employees, obviously worth it to him for an hour of our time.
So yes, I believe in TANSTAAFL - a firm believer... There is a cost to EVERYTHING, you just have to figure out what it is, and if you are willing to pay it.
Again... I am talking about big iron servers - not toy PCs...
I will easily agree that for Desktop PC environments, you might as well use software RAID - there just isn't any reason not to. However, for big database servers, and things doing massive ammounts of I/O (yeah - stuff that you can't even do with a standard PC based server)
The claim was made first that Software RAID is faster (I claim it isn't on the high end) then the claim was made that it would only take a fraction of a percent of a CPU - and I claimed it would take at least 5% of a high end CPU, and you are backing that claim up saying it is 22%.
Kind of like the people saying you don't need any fancy routers, just throw a few interfaces on a Linux box and route to your hearts content. Yeah - it works great for T-1 speeds, and a couple of other slow networks, but if you want to be routing multiple 100mbps interfaces (Gig now, if not 10 gig) you really nead custom ASICs to get you over the limitations of toy PCs and their bus architecture.
You really think a 6.8 Gbps stream will take a "fraction of a single percentage" of a CPU. Lets look at this... Round down to 800MBytes/Sec. How many instructions do you think have to be spent processing EACH byte. Realize that there will at least three read, a XOR, and a write operation for each word. lets make it an even four to keep the math simple so there are 800M operations that need to be performed every second on a stream of this size. Lets say a Nice 4GHz processor, running with 2 IPC (heck, lets make it four with dual core) and that is 5% right there.
Now throw in the extra memory usage needed (remember I am processing 6.4 Gbps instead of 4.2) and I get quite a few more cache misses making my "production" code miss cache a lot more often.
Now that we have gotten over the fraction of a single CPU myth... try again.
Well, software CAN NOT be faster if you are on a high performance RAID system.
Lets say you have a disk subsystem that can perform 10 GBPS. Now I will take all of that and run it over a PCI-X bus (same thing applies to PCIe except the numbers are higher) and get throttled to 6.8Gbps for a throughput of 4.3Gbps.
Now I have a hardware RAID solution. I get 10Gbps from the disks, process it on the card - ship 6.6 Gbps over the bus, no problem.
Now I haven't even mentioned the CPU utilization. Lets not go there, but yeah - if you are benchmarking Disk I/O Host CPU utilization doesn't matter. In real world scenarios where I actually want to process something from that I/O, I need CPU power available to do the real work.
Low end RAID - I am right there with you... might as well waste the extra CPU cycles available on your desktop system. In real server environments - no way... Hardware RAID all the way (oh yeah - and I do backups on my raid array so if the controller fails, just get a new one and restore)
Yes, can't get it to my house (Verizon screwed them there). I personally use DSL-only.net which works on the copper DSL lines, but would like the higher speed fibre lines that Verizon doesn't have to resell.
The players of World of Warcraft were left with a similar conundrum in March, when a group of gamers performed an act whose only purpose was to cause emotional pain. The death of a member of the community inspired her fellow gamers to hold a virtual funeral, which was raided by a malicious mob that made short work of the mourners, all of whom had relinquished their weapons as a sign of respect. Since the funeral was naively held in a zone designed for combat, few could question the legitimacy of the attack within the game's rules. None the less, the mourners were outraged, not at the penalties their characters would have to suffer, but at the brazen attack on their feelings.
One of the funniest WoW videos I've seen came from this attack. I was wondering how they went through the funeral attendies so quickly - now that I know those people were dumb enough to go unarmed into one of the highest zoned PvP areas... Duh - what were they thinking. Hold the funeral in the undercity or something
Just got of the phone with FIOS (verizon) - for 34 dollars they can get me a nice fast completely non-functional DSL connection. Of course to get what this geek really REALLY wants (simple, static address - ToS that allow me to run services) will cost 99.95 a month for the same upload speed.
Idiot on the phone line couldn't justify the 60 dollar cost difference, other than to say that is the price difference between static and dynamic IP (well, the download speed on the static was a little faster - They couldn't price out a static address on the slower speed).
This was all started by Verizon sending a flunky to my door saying they were REQUIRING me to change to FIOS. Was a fun discussion with said flunky -
"Will you allow me to run a service" "What do you want that for" "So I can run my e-mail server" "We provide an e-mail service" "No you don't" etc. etc. etc. Turns out they really were just looking for upgrade oportunities - wonder how many of my neighbors fell for it (I know one didn't because said flunky said the guy down the street was asking the same questions "The one with the Dogs?" "Yeah, how do you know" "Because he is a system admin - and he is smart"
>Nothing wrong with copy & paste. My system has three different ways to do it.... all incompatible
You must be a Windows user.
Strange - I am only aware of three cut and paste mechanisms on Windows and they are all compatable with each other. Nothing drives me nuts in Linux like trying to cut something out of a KDE window and paste it into a Gnome window. At least on Windows it is: Ctrl-C Ctrl-V Right click - Cut Right click - Paste menu->edit->mark menu->edit->cut menu->edit->paste Which one of those is incompatable?
Now show me how the different clipboards that exist on a single Linux Desktop can even cut from one and paste to another.
Wow - what insiteful reporting. Get rechargable batteries and have one set in the charger and one set in the controller. How did this get posted to slashdot anyway - TFA certainly didn't mention anything that would involve openning a case - just "Let me use my 7eet skilz to use a wireless controller". How lame. Let me get back to my prototype Conroe rig and I'll get back to you with an ultimate system in a month.

If it is a window - use APISpy to track windows API calls - look for a call to CreateWindow() and track where it is coming from.
All of that said - it is much cheaper to hire in places like Iowa, but the talent pool (or the ocean for that matter) isn't there.
Very hard for a company to do.
What other alternative is there now?
