I don't think that is the main reason as Android now uses MTP to allow concurrent access to the SD card. It is my belief that one of the reasons behind the lack of any sort of SD card is the possibility of it impacting the user experience. If you put in a cheap slow SD card then the apps located there slow to a crawl. With the built in flash storage, it should run to whatever standard Google demanded. I also believe this is one of the reasons Apple refuses to include expansion capabilities, the other of course the ability to charge a huge premium on upgraded space. For the Nexus 4 the bump from 8 to 16GB is only a $50 up-charge which isn't that bad in my opinion.
I am in a similar boat. 36, two kids, 14 and 12. They are discovering new things and really helped to increase the realm of items I was interested in. I have delved into electronics which has given me even more of a sense of how things work at a low level. I bought an old 100MHz Tek 465M scope and I was amazed as what I was able to see on screen and deduce what was happening at a low level.
I am not the youngest in my group but I am the most skilled and I take it upon myself to delve into technology that will improve our efficiency and help with stability of our systems. Really the end users don't talk to you until there is a problem.
As you grow you will also learn that if you listen well enough you will start to find out what problems a user won't tell you because they may think it is unworthy of your time. An example was that people were having hard times moving and copying files on our large clustered storage. They would mount it to their Windows box and copy it between systems this way. Using local Linux tools like cp to copy was much faster due to 10Gbit connections on the nodes.
Sadly you will find companies where old IT is entrenched and sometimes the best option is to move on.
My Samsung Galaxy S (Vibrant on T-Mobile) has been the toughest phone I own. I even managed to drop it in a pool, let it dry out and it is still working today. The gorilla glass on this phone is amazing. It lives in my pocket with no screen protect and with change, pens and sometimes keys and doesn't have any noticeable scratches. About the only thing that bothers me is that the GPS is crap, but that isn't high on my list of priorities. I will definitely go with the SGS II or the SGS 3 if that is out by the time I can upgrade late next year.
This post is full of good information. I have been managing HPC for seismic companies for the past 8 years now. I regularly use xCAT as I find that after a few nodes automation is the way to go.
You will find that most clusters run RedHat or a variant of the OS. Most places run CentOS on the nodes and have a machine with RedHat stashed around somewhere in case a problem occurs and they need to reproduce it on a "supported" OS.
Why is there a requirement for a full blown X install? Are these machines desktop boxes or are they racked? Typically you have a thin client software installed at the cluster gateway. We use both NX and ThinAnywhere today.
Nor will you be charged for going over your cap, simply throttled. Thank you T-Mobile for being clear in your advertising and dropping the frequently inaccurate term of unlimited for your data plans.
I love your feed, I have been following you for quite a while on twitter. I know a lot of the tips and tricks that come up but at least once a week something new to me shows up.
I have been a systems administrator for over 10 years and I find the command line invaluable. Even the geophysicists ask me to write quick one use awk scripts to format a file into something usable.
While I agree for the most part I think you may be missing an important facet of a software based inventory system.
With a software based system that is kept up to date you can know without having to count physical items if you have enough parts for a particular project.
1) Buy a SIP to POTS adapter 2) Install asterisk on your Linux server (You do have a Linux server right?) 3) Create a web app, preferably Ruby on Rails, that connects to Asterisk over the management port and dials a phone number and rings it back to your home phone line 4) Profit until the system breaks and the wife wrings your neck because she can't call to make her beauty salon appointment!
A cluster is a collection of, usually, homogeneous compute nodes. They are usually split into MPI and SSI, Message Passing Interface of Single Server Image. The latter is a bunch of machines trying to emulate a single system and is not commonly found in the HPC world. You are more likely to find MPI setups where each bit of processing can be broken into smaller pieces and distributed to each node.
For a render farm you can have machines with no knowledge of each other as they can each work on a separate set of frames. If the rendered is MPI aware it can ask neighboring nodes for data.
ROCKS Clusters are MPI based but can be used as individual machines. ROCKS strength is its simplicity in managing the OS image on each of the nodes. You plug a machine into the network, flip it on, wait for ROCKS to find the MAC broadcast during PXE boot and then assign it to a predefined image group. Minutes later you have a machine installed exactly as all other nodes on the cluster are. This is sometimes vitally important as certain software may not work with a different revision of the OS.
ROCKS allows for easy management and easy expandability. If you need more compute power, plug in new nodes, collect the MACs and image.
We have XCAT and post scripts setup to do the majority of our work. Images the machine (PXE generation, DHCP config), installs files based on group, sets the ganglia config. I don't have any monitoring setup on compute nodes as I have ganglia open daily to watch for cluster node failures. Zenoss is done afterwards as I have yet to find a good way to automate that.
As has been noted by other posters, border searches have been allowed for years.
A lot of people also think border searches are to prevent bombs, guns, etc. These searches are not only limited to bombs, guns or other destructive devices. Going through customs you are asked if you have an contraband, fruit, etc. This is to prevent damage to the economy and ecology.
Kudzu is not a native plant to the US. It was imported into the US and now grows throughout the south eastern United States.
Mad cow disease was also a big issue with border control.
As for searches of laptops, is child pornography not a danger to society? Of course the question then becomes, what material becomes a "danger to society".
Windows NT has been SMP capable. Win95/98/98SE/ME have no SMP ability.
From Windows 2000 on, with the exception of Windows ME, all version are Windows NT based. Windows Vista is the next OS from Redmond to take a huge derivation from past Windows root.
I'll agree, NTFS is not a horrible filesystem, Windows is not a horrible platform, and if this was done by someone other than a rep from SnapStream, I wonder if they would have used MythTV and Linux or Windows XP MCE 2005?
The biggest problem I see is RAID 0, for a small cost premium, RAID 0+1 may have been a more prudent way to go to keep speed and redundancy.
In math, I think showing work is one of the most valuable aspects of the test. This shows a deep understanding of the problem at hand. Why not have final answers on a scantron like sheet and once marked wrong, review just the incorrect answers on the work sheet they turn in along with the scantron. Grading will still take time but you will instantly get to the incorrect problems and help the people who need it most.
Here is a link to an Epic developer talking about how the Unreal 3 engine will use this PPU.
Very interesting technology, comes with its own SDK and should be able to handle many times the amount of physics based objects in a game than the CPU can handle now.
Any network latency is much higher than even your main memory.
Ideally graphics memory has that is very quick and dedicated to the graphics gard itself.
Now you may be thinking of distributed rendering, which is a non-realtime process and lends itself well to running over a distributed network render.

That is only 20% of the single digit numbers, 3 through 9 have escaped this time!

Just my quick $0.02 on the subject.
Time for overkill solution number 1:
1) Buy a SIP to POTS adapter
2) Install asterisk on your Linux server (You do have a Linux server right?)
3) Create a web app, preferably Ruby on Rails, that connects to Asterisk over the management port and dials a phone number and rings it back to your home phone line
4) Profit until the system breaks and the wife wrings your neck because she can't call to make her beauty salon appointment!

The rumor is that Nvidia is dropping the 7800GTX 512MB configuration.
Well, now all we need is a "Doesn't play Ogg Theora, I'm not getting one" troll.
Yay for trolls!

Isn't this how Skynet started? I'll just wait for the net to gain its own identity and try to rid itself of the real problems, the users!
Why are you mixing the military, nudity and computers anyway? Don't you get court martialed for that?
Very interesting technology, comes with its own SDK and should be able to handle many times the amount of physics based objects in a game than the CPU can handle now.
The Top Thrill Dragster at Cedar point lasts about 15 seconds and you typically wait in line for about 2 hours.
It was a great ride though, although I liked the Millineum Force much better.
