Comment Cisco can blame someone else... (Score 5, Informative) 36

Nuova Systems developed the Nexus switches (for cisco) and then Cisco bought the company. The Nexus 3000 is also listed as using more off-the-shelf merchant silicon. So maybe the just used the reference code that came with the cheaper chips? In the end it's still Cisco's responsibility to secure the systems they sell no matter where the stuff came from. This is not the first time cisco took over another company's work...

Comment Re:Multiple heads (Score 4, Informative) 202

This has been done before.... Both outside/middle dual heads and dual independent actuators on each side. Multi heads can increase performance, but cost space, power, and money. Also more parts = lower MTBF. They don't increase storage density. If you want performance use SSD.

If it won't boot and you can't erase the on-board flash then try:
  1) Sell it for parts and hope someone does not fix it and access your data (use a sticky note to kindly ask them to erase it for you)
  2) Dump it at your local E-waste center and hope some does not pick it up out of the pile (and see #1)
  3) Microwave it to fry the chips and hope you don't burn down your house (please upload the video)
  4) Use it for target practice (9mm or larger please, full auto would be best) and then crush it with a steam roller (once again, please upload the video)
  5) To meet your non-destruct goal, if you have skills: unsolder the flash chips, erase them in a programmer, reinstall the blank chips.

Or as pointed out from before (but it's too late), encrypt your data from the start and reset the keys.

Comment Old cell phones are kids toys (Score 2) 171

The kids love to play with real cell phones with buttons, the older the better. Flip phones are the most fun. The old StarTAC and RAZR phones are the best toys, even better when the batteries work. With iphone/android phones you can still play games if they are still working, otherwise they are just paperweights without buttons,

United States Begins Flying Stealth Bombers Over South Korea 567

skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

Comment SSD write to death chart P/E Cycles. (Score 1) 267

This chart is almost 2 years old now, but it is a fun read and has some good testing information:

I have read that some of the newer SSD have only 500-1000 P/E cycles (eg. Kingston V300, Samsung 840), but I don't have proof. It is well documented that most of the current MLC drives have 3000 to 5000 P/E cycles while may of the SLC units are 100000 (eg. Intel X25-E, SuperSSpeed SLC S301).

Here is another good article about TLC SSD:

You have to buy and use the correct type of SSD for your application. A new TLC SSD should not be used in any write intensive application (eg. ZFS ZIL) but it may be great for that new fast laptop that can use the speed and does not do a lot of writes to disk. For most standard uses a good SSD will outlast the laptop/desktop where it is installed. The key for good SSD use is detection of pre-failure (SMART is a good start). The SSD is now a consumable part, just like the battery or brakes on a car. We all know drives fail, but standard hard drives don't have the same fixed life expectancy as an SSD.

Don't forget about Write Amplification. It can help kill a drive faster than total bytes written:

Comment Google is your friend...but try non-computer camps (Score 2) 177

I have nothing to do with this site, but it looks like a good place to look.

At that age I remember having a great time at summer computer camp in Vermont (2 weeks sleep away) in the early/mid 80's. I had the best time doing the non-computer things (like sailing on Lake Champlain), but I always did as many computer related activities/classes as I could. We got to use the newest Commodore CBM with Pascal! As an advanced class I also learned Fortran on the big IBM (System/34 I think). I don't use the old programming languages any more, but I'm still happy to take out a sail boat!

If you're going to visit the USA I think you should focus on non-computer activities. Like visiting the great national parks, such as the Grand Canyon, Yellowstone, and a hundred others that are unique to America. Spend time programming nearer to home. You can always play with a computer in a windowless closet anywhere!

Comment Cisco 2950T-48 Switches (Score 5, Informative) 199

One of the photos shows a Cisco 2950T-48 that provides 48 10/100 ethernet ports with 2 GigE uplink ports. This seems like a simple setup for lots of tables. Drop a switch at each table and feed run one cable back to the core switch for the area. If Cisco provided 300 of these switches that gives you 14400 100meg ports for users. Then a few core switches with a stack of non-blocking GigE ports and some 10GB or 40GB uplink ports to the core routers. Easy... I'm sure several companies (or universities) had similar setups. The amazing thing is the built it as a temporary setup. The real job is providing safe power and cooling for all users.... maybe next time they can provide PoE for everyone and require "green" computers!
