I assume that the train cabin would be similar to a plane cabin. There are usually a minimum of 4 doors on any airliner cabin. If they solved the vacuum problem there, they can do it on the ground. Building train tunnels underground would probably be the best bet for keeping vacuum in the...

I agree with logitech... and 2.1 if the sub size/placement isn't an issue. On the logitech 2.1 setups I've seen, you cannot bypass the sub like you can on some other brands. One of the things I like best is the (corded) remote volume control/headphone jack -...

Something I'm missing? http://www.newegg.com/Product/Product.aspx?Item=N82E16820139075 http://www.newegg.com/Product/Product.aspx?Item=N82E16820148347

On drives that cannot be wiped with DBAN, I usually use a cordless drill and drill 3 holes completely through the drive. Drilling is surprisingly quick, maybe 10-15 seconds per hole.

Dell lists 16 as the max because that's all that will fit in their rack/tower chassis. The cards will actually do 32 drives per array and 8 arrays. So you're looking at 256 drives. Obviously, with only two 4x connectors you're using port expanders/backplanes to get to that number and performance...

Fluke, Exfo, and a few other companies make ethernet test sets. Plug one in at one end of the network and one at the other end and start the test. By testing individual devices/links you should be able to isolate the problem to one or more devices. For a fraction of the price, you can get the...

Did I miss something or is there a reason I do not see the suggestion that you should get a nice RAID card? 1. Online capacity expansion: check 2. Uptime: check 3. Data Integrity: check 4. Speed: check

There are many ways to limit bandwidth. Depending on the way it's done, this makes sense. DSL, cable, and analog modems all listen, test, and grab parts of the frequency spectrum available on the wire when they boot up or initiate a connection. This is the available bandwidth they have to work...

I was recently gifted one of these by a family friend who had had it sitting in the basement for a few years (unused). Definitely a good starter plane which got me interested in the sport without too much of an investment. The plane was recently carried off by a large wind gust into some...

Bozo, I think what you are describing may be a matter of efficiency vs efficacy (effectiveness). You might find there are diminishing returns when running the pump at faster speeds, but there are still returns. If one were concerned about efficiency (as is often the case with Heating/Cooling...

I've had good luck with Axis cameras. They might be overkill for what you mentioned though. They make their own recording software or you can use your own (there are several, including free, software packages for grabbing images from any IP based camera).

If you want to continue recording in the event of a failure, I'd skip RAID 5 or 6, as their write performance is going to suffer greatly in the event of a failure. I'd probably also skip a hot spare as the rebuild may likely do the same. RAID1 if performance or capacity are not factors or RAID...

One of the problems I see with these Dell/Compaq/HP/Gateway P4 refurbs are bad caps and dust clogged/dead fans. They seem like good deal, but buyer beware. Certainly check under the hood and power up first if at all possible. To run WindowsXP w/ service packs and modern AV seems to take at...

I think I've only had one desktop board that didn't get a CPU upgrade (or perhaps a downgrade) at some point in its life. And I got that one used. But as I get older I think I'm starting to think of PCs more as a commodity item. I'm pretty tempted to buy an off the shelf Dell when I finally...

David, I think it's amazing that you've envisioned this product that has taken more than 2 years to come to market, and even then seems potentially immature (I just updated to the latest Radeon driver suite and it seems to have broken my dual monitor display on a 4670)

btw, I think pretty highly of HP switches. I've worked on some older HP stuff that had a (very) limited implementation of 802.1Q/VLANs. I'm sure their new stuff is better in that regard. They've always had a good web interface and their reliability has been as good as any other. I'm sure...

per port? No, I agree that is crazy. I try not to buy into that type of licensing scheme (for any product). We buy most of our network equipment second hand from a reliable reseller. The switches in question have been in place longer than I have. Other than a buggy version of CatOS on one of...

Just complaining about the high power usage of the Cisco gear. At work we have three 48 port 10/100 switches providing the bulk of our desktop connectivity. Each switch is using an average of ~ 100 watts. Between the three switches and some misc equipment that's all the puny 450VA UPS they are...

oh, I just re-read the title... no warranty left on this d620 dell outlet deal.

I just came into possession of a used D620 if you're interested in a previously owned solution. For what it's worth, I've used a cheap little no-name USB/Serial adapter for Cisco/Redback gear on my Inspiron laptop and Vostro desktop. Works well in XP with the right drivers - surprisingly, the...

Seriously though, I appreciate the low wattage, fanless designs. We currently have a stack of Cisco 48 port switches that we need to do something about. Unfortunately, Cicso switches that provide more than 48 ports don't really use any less power.

The specs state it's only good up to 10,000 ft altitude... guess people on mountain peaks must forward their packets with non HP gear ;- )

I tend to agree with the close tab consistency making a noticeable usability difference. There are options within firefox to change it's behavior within about:config. For one, you can have a close button on all tabs or only the active tab. Second you can set the tab widths. Buy utilizing both...

For example, place this cgi file onto a webserver that supports execution of cgi files (the file typically needs the file to have +x permissions, may additionally need the ExecCGI permission set) and then access the file in your browser. top.cgi: #!/bin/bash echo Content-type: text/plain echo...

That looks like the output from the 'free' command (which really is just reading the /proc/meminfo file) turned into HTML with some minor CSS styling. Something like that (reading, parsing, and formatting) could be implemented in bash (through CGI), php, perl, etc. Then you'd need a web server...

I second this. I'm using an older copy of the Freeware version of SyncBack as a means to keep one of our Windows servers in sync with a backup for years. This involves a regularly scheduled backup of a large MSSQL db dump, several GB worth of small files (many of which do not change), and a few...

i just wanted to 3rd that, I used TrueCrypt to encrypt an existing Windows install on a laptop. Great software!

I've ran 1000BaseT over cat5 cables with mixed success. Sometimes it works fine, sometimes you end up with 1000Mbps one way and < 100Mbps the other direction. The NIC's don't seem to identify or report this as a problem and happily continue to negotiate at 1000Mbps, but with terrible...

btw, I would definitely recommend the "thingies into the ports", assuming you can get them that will support your fiber. SFP's and GBICs act as a native switchport - allowing the switch to configure and collect data linke any other switchport. Often, the use of stand alone transparent bridges...

DD, are you sure that long run is multimode - and not single mode? Multimode 50 or 62.5micron fiber is typically only good for up to 300-500m using 1000BaseSX (the typical fiber standard for ethernet switches). To go farther, ethernet switches use single mode (10u) and 1000BaseLX (aka LH in...

It does, but it doesn't re-size the underlying file system.... so what's the point? LVM is basically software JBOD. It creates logical containers that appear to be contiguous to the block drivers in the OS. This allows you to extend a file system across disks. It has all the disadvantages of...

All DVDs and the majority of older blu-ray are encoded with MPEG2. The majority of newer Blu-ray discs tend to be encoded using AVC. Perhaps your hardware does not support MPEG2 decoding or your software does not support AVC decoding - i forget which problem you had (or perhaps you had both)...

I distinctly remember using the RAID4/5 driver (each driver is basically separate). My system became unresponsive when an IDE drive died. Since the system was unresponsive, I was forced to hard boot. This left the array degraded (dead drive) and dirty (drives out of sync). The RAID4/5 module...

The benefit of CentOS is that it is using code that has had a longer period of time to be vetted in the community and by RedHat. This code freeze does have the distinct advantage that it allows documentation to be written based on the code that is published and continues to be distributed for a...

I would also nominate a redhat based distribution like CentOS or Fedora. I found that the whole disk encryption at install in Fedora 11 and 12 worked really well on my laptop. I don't know that I can recommend linux software based raid - the last time I used it (~ 5 yrs), it was immature...

As has been pointed out in previous threads - the Dell PERC 5/6 cards are cheap, work well, and available on ebay as system pulls. The Dell PERC cards are rebadged LSI cards with perhaps some slightly different firmware - they work fine with LSI drivers/software.

HT-RC160 as part of this system. The 707 looks like a newer version of the 507 and 607 (what I was originally looking at), but the advantages over the HT-RC160 (extra pre-outs, svideo, front HDMI, and an additional coax audio) weren't worth the $300 price premium to me. Oh, and I really like...

Apparently he decided to give it another go. I helped him with a few of the options over the phone (based, in part, on Newegg feedback about the router) 1) Disabled auto channel option (manufacturer suggestion posted in response to a newegg review about the same problem) 2) Disabled 40Mhz mode...

It's on my netflix queue, with about a dozen or two other BD titles to test out the new Onkyo and PS3 combination with my Bravia.

Did you buy a pre-made length or did you terminate it yourself? I've thought about running a line to a friend's house, but at ~ 100 yards straight line (and probably 200 - 300yards going along property lines) copper is out. Wireless is a bit tricky since there is a house in the way, and I don't...

I've successfully used recuva in the past to pull data off of corrupted file systems. I have not used it with a RAID set though.

I double checked and the latest kernel from CentOS 5.4 (if you have version 5.x you can upgrade to 5.4 via yum) includes NTFS support. If you're running the GUI and have automount enabled (default) it should work automatically, assuming the fs is not dirty. more info on the centos wiki...

Just to throw this out there. A friend and I were at Microcenter and he was in the market for a new router (Netgear had been freezing on him and he had never had good coverage in his home). Based on coverage I suggested a 2 or 3 external antenna model over single/internal antenna models...

There should be no problem doing what you want, and you don't have to worry about using separate protocols on each NIC or disabling any protocols. This is purely a question of routing and it sounds like the computers are attempting to access the internet through the crossover link instead of...

I think it's great that wikipedia and google are able to make information so accessible to the average person. These are extremely powerful tools because of the knowledge that can be shared. Some people may scoff if you mention that you "read it on wikipedia", but I feel that most of the...

3600 or better routers should be able to handle at least 10Mbps through a l2tp tunnel. Again, you're probably looking at 10x the power usage, and I don't know that the cisco will play nice with non-cisco gear at the other end (I've even had trouble between two cisco devices if the terminating...

My aging p4 2.8GHz shuttle HTPC was having problems playing the movies I was throwing at it and was in need of complete replacement. A ps3 was a nearly drop in replacement that would play my media, offer BD support, has solid HDMI compatibility and could play games. The PS3 was about half the...

I've had good luck with Linksys WRT-54G and WRT-54GL models. I've used 3 netgear products (both b and g variations) and all became flaky after a couple years. Regarding compatibility, never had an issue with either of these brands, but I do have a problem getting my blackberry Perl Flip to...

If you have one at your disposal, you might do an AMD vs intel comparison. I've seen some (poorly optimized) tasks complete much faster (clock for clock) on AMD hardware vs intel.

I just got a new slim 120GB PS3, it is quieter during gameplay than the wii - inaudible from where I'm sitting (~ 8-10 ft away). The wii was audible during quiet moments in gameplay (like loading screens), due to the spinning disc. I haven't noticed this from the PS3, but I'm sure the PS3 will...
