How about the Mac Pro? The last time they did an update on that machine was in 2013! All of the hardware in that product line is at least three years old, and a good portion of it was about a year out of date when it came out in 2013. For a machine that costs upwards of four grand, you are certainly not getting your money's worth!
You can get a significantly more powerful machine today for half the cost.
Folks should take a look at the streetview shots of the Midway Atoll. Ducks everywhere, and you get to see the old military installation that the US abandoned years ago.
Even with homeschooling, graduation requirements typically mandate 1-2 years worth of high school level science courses. It doesn't have to be physics, I guess, but two years is still the typical minimum, and three or more for a college prep degree...
I know that the refill phenomena of sucking until it is dry is potent with me, which is why I typically order water in restaurants, because I know that I am going to go through three or four glasses easily while I am there.
Some folks in the community are already bandying about the idea that this boat be turned into a moored training ship for nuclear propulsion training, the way they did with the MTS-626 and MTS-635.
On those ships, you do not need to have all of the electronics gear, torpedo armaments, or anything else... you just need an operational reactor, which is all towards the aft end of the boat in the first place. As the fire occurred in the forward end of the boat, this is a very likely scenario. Since the MTS-626 and MTS-635 are getting older by the day (they are old Lafayette class boats built in the early 60's!) and there is a need for replacement anyway, this seems like a good way to go.
This sort of reminds me of a short story that Asimov wrote about a boy who decided he no longer wanted to use the transporters in every home in order to go to school. He preferred walking to school each day instead, much to the horror of his mother.
I first started out on GatorMUD, which was a mush (I believe) at the University of Florida. I played and developed on that for a while (built all of 13th Ave!) then went on to KoBra mud for a while.
Eventually got sick of just playing and decided I wanted to develop, so I got with the math department and started up Muddog Mud. Worked on that mud for a number of years before it was eventually wiped out.
During that time I also did quite a bit of playtesting on Silly Mud, a Diku style mud at UF (anyone remember CircaOp?)
I bought an 8 port gigabit switch and use that for my network, and my router now only deal with things that are actually going to/from the internet.
I tried this myself, only with a 24-port gigabit switch. Still had the same problems. Once I upgraded to an low-end enterprise level router (3com 5231) the problems went away.
Yerp. I had gone through two Linksys models and a D-Link model before I got tired of the constant reboots, at which point I E-Bay'ed a 3com 5231. That thing works like a champ, has plenty of capability and has yet to fail on me.
In other words, I chose fast and stable and sacrificed cheap (sort of... a 5231 was not cheap when it originally came out)
I disagree. I have done a lot of reading on the history of computer culture over the past fifty years, and this story reflects the histories that I have read. It is a good, introspective look at the culture of computing at that time.
In addition, even things like Infiniband have come down significantly in price recently. It is now possible to get Infiniband HCA's (4X SDR) for $125 USD new, and an 8-port switch for $750 USD.
With that kind of pricing, it is now plausible to setup a small cluster in your own home with very high speed bandwidth between nodes. 4X SDR Infiniband is capable of sending data at 10 gigabit speeds, and running IPoIB on it gives you the same bandwidth as the much more pricey 10 gigabit ethernet that is out there.
I recently found a good mechanic in town, and I won't be going to anyone else from now on. I was losing a good amount of power steering fluid daily, and knew that something was wrong with the system.
Took it in, told them what was wrong, they inspected it, found that the power steering piping on the underside of the car had rusted through, called me to let me know what they had found and that they were proposing to run a new line that they would bend themselves instead of replacing the old one with a factory part, since the factory part was ungodly expensive. I agreed, they ran the line, and I had the car back that day. Total cost of parts and labor was less than the cost of the factory part alone.
They will continue to get my business from now on.
Also, that article... I found it interesting that a majority of the comments to that article were basically saying the same thing as here... that it was biased journalism.
You know, I wish schools taught economics more thoroughly and would define for people what, exactly, a monopoly is. Because Microsoft is not a monopoly. They may have a large portion of the market for their products, but they aren't a monopoly.
Yep. We had that problem as well with some big file servers and NFS. It turned out that pdflush was set to flush data to disk once every five seconds if filled, and once every 30 seconds if stale. This was KILLING our NFS performance. Of course, once we found the real performance tuning points in/proc/sys/vm, we were home free on that. Using nice as a performance tuner of a system is just silly. nice can be used to tune the performance of programs interacting with each other to some extent, but when it comes to the system as a whole, it is a relatively small subset of the whole she-bang.
It sounds like someone in their IT or purchasing department needs to do some research on what exactly Dell has, because the Optiplex line is the way to go for maintaining consistent equipment.
I am just glad that I remember, even though I was not alive at the time. I have been to the site, and revere those that gave their lives for the space mission.
OK, I read the fine article, and I now have a question...
Because they are running two different chips that have different cores and memory controllers, etc. I was wondering if they thought about running the two chips in opposite slots to see if there was a difference in performance. I imagine that there may be differences, perhaps even significant ones.
I have users that are now getting very close to exceeding the 2gb limit in mailbox size, and going to a 64-bit server would alleviate us of this problem. Disk is cheap, but when the system can't handle >2gb mailbox sizes....
Oh, they can dictate anything that they want. Not that anyone else has to listen. Regardless, they do have a lot of power in this sort of thing, and if they decide that the next versions of their server-based software is going to require 64-bit processors, then very likely the users that want that software are going to follow suit. There are a lot of advantages to going to 64-bit systems in this ever-growing world where file and data sets are getting larger and larger.
Something else I forgot about is the actual hardware... you may want to take a look at the nStor products. Their hardware RAID systems are relatively economical, and you can go to fibrechannel drives with fibre connected boxes quite easily with their equipment.
I work in a high performance computing center, and we just recently acquired a new cluster. One of the major items that we looked at was the amount of heat that is generated by the systems, as cooling systems for large amounts of equipment can be quite costly. We went with AMD dual core systems because we were able to load up with twice the number of systems and cores (thus a 4X overall improvement in number of processors) for a heat load that was actually less than the old system we had that was running Intel Xeon processors.

I left out the link on purpose... get on Google Maps and search for it yourselves as a lesson in Geography!

...go hand in hand.

You may want to take a look at IBRIX systems. They do a pretty robust parallel file system that has redundancy and failover.

Shifting to a DC powergrid helped a lot too.
