There's only so much RAM in those beasts and they have to fit a ton of features into that space so having a hard limit on datastructures makes sense since then they can make sure they never exceed the devices capabilities, it's not like they have swap space to fall back to =)
That's why Blackberry's are better than Treo's with Good, as soon as the device can talk GPRS or better it will get the wipe signal based on its PIN, it's not tied to the SIM.
I'm assuming they are using the secure instruction included in recent Intel CPU's to talk to the TPM1.2 chip in the laptop and deleting the decrypt key from the keystore therefore making the recovery from FDE like BitLocker basically impossible.
Btw the biggest gain NTFS can get from defrag ISN'T available in the free defrag utility that comes with the OS. The biggest gain is in defragging the MFT which isn't officially supported by MS except at boot time and as far as I have been able to find there is no product that can launch at boot time and use the MS API to defrag the MFT. I've used DiskKeeper to defrag the MFT but I throws all sorts of warnings at you so I'm not sure how safe it really is.
I only use defrag on the box that builds the code for our ERP system because it can significantly reduce build times. On the other ~150 servers there isn't any real performance gain to be had because they are either not I/O bound or like Oracle they have their own way of dealing with scattered I/O.
If it's like Lenovo's solution you have two levels of authentication, first the SMS number which sent the message is whitelisted (fairly easy to spoof I assume) and secondly the messages are cryptographically signed. I believe the whitelist feature is to keep from being DDOS'd with bogus messages which the card would have to attempt to decrypt.
The real question is, are these checked builds? I know MS used to only release checked builds during beta/RC cycles but I haven't participated since Longhorn. If they ARE checked builds and they are still faster that's quite impressive because they should become leaner and faster once the debug code is taken out.
Could be worse, it could be a L3 switch with hardware MAC tables in the ASIC that becomes crippled when the ASIC's table becomes overrun and you have to do switching with the SLOW CPU. The fact is that there are resource limits to all hardware and sometimes limiting things in software is better than allowing a buffer overflow.
This is industry standard checksumming to ensure end to end data integrity from the disk to the storage system to the HBA to the OS to the app. I'm quite stoked for this since my SAN vendor (Xiotech) has the first system to support the standard (Emprise 5000/7000) and we have Oracle 10/11G already in our environment.
It doesn't matter much. This patch adds T10-DIF which basically brings minicomputer level data integrity to the commodity computer market. It adds about 1.54% to data storage requirements (8 bytes of ECC per 512 byte block, just like the AS/400) and some small amount of code at the OS and APP layers to check the CRC's. With Oracle I would imagine this might actually INCREASE performance for the most fault intolerant environments since it wouldn't need to do a read after write if the storage system acknowledged a successful T-10 DIF block save.
I know full well where the tech came from, I supported the former Aironet employees for 3 years after they were bought by Cisco =) The VxWorks stuff was more stable than IOS at least for the first year or two after IOS was ported and if our AP's at work are any indication that's still true as of a few years ago (noone is using them but they still crash once in a while).
p.s.
An interesting aside, the VxWorks software was also easier to maintain since it was written in modern C++ vs old straight C for IOS. This became very clear one day when a particular large school called and said all of their AP's were rebooting randomly at fairly short intervals. It turns out they had a HUGE flat network with 28k+ visible MAC addresses. This was more than the AP's were speced for but Cisco couldn't just let a large customer's install die, so after they figured out the cause they had to come up with a solution. For the VxWorks code they simply modified the MAC table class and recompiled, a patch was available within a few hours of the trouble starting. The IOS patch was much more difficult with tons of searching through header files and later after the first patch failed searching through the entire codebase. The small minority of new AP's which were running IOS were flashed in the field to VxWorks with an unsupported dev tool because officially the 'upgrade' to IOS was one way.
Which is funny because they moved their enterprise AP's off of VxWorks and onto IOS so that the switching guys would be more comfortable admining them.
Doh, make that ~1.3*10^9 for the oceans, stupid online references using the european definition of billion. Still makes it off by more than an order of magnitude.
Actually I think the biggest post P3 improvement has been the move to dual core as standard on the desktop in the last couple years. At least on Windows the non-blocking nature with a stalled thread is huge for overall system performance and UI snapiness. It's great to be able to get those benefits without a $200 motherboard and two CPU's =)
I can't wait for the multichip Xeon's based on Corei7, Intel might finally have a chip that can compete with AMD in the database space next year. Oh and for your raid problem, use HP, a RAID array is portal across all systems and controllers that use the same generation HDD's. I have picked up an array out of a server, put it into a MSA and mounted it through an HBA with no problems then expanded the array online with additional disks to grow capacity =)
Funding is a necessary but not a sufficient condition for academic success. I attended a school district that spends about half as much per pupil than the big city school district despite having about 3x more special needs kids per 1000. Despite that lower funding level they achieve a 90+% college attendance rate vs about 20% for the large school district. The difference is that in the district I attended (and the similar one my children now attend) the parents expect their children to succeed and put a great deal of effort into making sure that happens.
Pretty sure he's talking about the fact that you need a uPnP client on the PC to talk to the services like Hulu instead of having a client available for the console. The fact is thanks to the standardized and open way the PC works it's easy to write a client that grabs internet content and then streams it back out via uPnP vs the difficulty of writing and publishing a client for each of the closed console and media player clients there are out there.
Not more hospitals than average, more ICU patients than average. Michigan has about 3% of the US population so based on the numbers in the article I have to assume they have a slightly lower than average number of ICU patients per capita.
Cocaine leaves are STILL chewed in the Andes where they act as a vascular constrictor thus increasing the rate of bloodflow and hence the ability of the circulatory system to carry oxygen.

UAC is being scaled back in Win7, even in early builds it's supposed to be much better.

Correct, the total volume of the oceans is ~1.3*10^6 km^3, the volume of the moon is ~2.2*10^10 km^3 so it's not even close.

If only software raid had battery backed write cache it might be an option for real production systems....

Most well run ones, though generally not more than two and there are sometimes hidden connections between the two that leads to a common outage.

They just taxed it and refused to issue tax stamps so the possession without a stamp was tax evasion.
Ohio's still 65 max thanks to our wonderful state patrolman's union =( For a list of speed limits see this site.
