I know you get some USB type SSD's, but people still refer to them as SSD drives, and not USB drives Depends on what level you are looking. Generically, it is a sequence of blocks, just like a rotating hard drive appears. Proper ID commands can find out more detailed information on it. Some computers, like the Macbook Air, have SSD but it is NOT SATA. It is plugged into an expansion slot. I have also seen other SSDs that plug into PCI Express slots. The OWC drive I'm looking at is a 2.5" SSD drive with SATA II 3.0 Gb/s interface. It can also be used with a SATA -> IDE/ATA adaptor, that would make it appear to the OS as a P-ATA EIDE drive. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro/Legacy_Edition "Add a technological supercharger to your existing Mac or PC with the OWC Mercury EXTREME Pro Legacy Edition SSD.

Includes IDE/ATA adapter for use in 3.5" IDE/ATA desktop drive bays. With PATA adapter removed, SATA I (1.5Gb/s) and SATA II (3.0Gb/s) interface supported, SATA 2.6 Compliant." So I could use this in a desktop as an EIDE ATA 133Mbs drive with the PATA adaptor, or as a SATA II desktop drive, or in a laptop as a SATA drive. The only thing I don't like is the fact that it's a MLC SSD. I'd much rather find a SLC drive, due to the x10 reliability factor. The SATA -> EIDE drive adaptors are on ebay cheap. I think this is a 2-way adapter; SATA -> PATA or vice versa. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320645765177&ssPageName=STRK:MESINDXX:IT The other option is to throw in a PCI(e) SATA controller card, and run the SSD as a native SATA II drive in a legacy IDE desktop.

Why should a PHP 5.3 package provide PHP? To many libs are different, and it would allow for the installation of something like php-ldap from base to a php53 which provided the php dependency. That is not how RPM's are supposed to work. PHP 5.1 is significantly different enough to warrant a different package. Would you package postgres84 to satisfy postgres? No, because it would be wrong. A more correct solution would be to change the dependencies for the cross-php packages to allow for a php or php53 to satisfy. -- Steven Crothers steven.croth...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Many packages work just fine with 5.3; a simple -compat package could Provide: php and permit such to install and work without issue. Note that I am not arguing that there are some significant differences between the legacy 5.1 and the more modern 5.3 only that for the example I cited in a later reply should work with the 5.3 from upstream if the needed deps were matched. And to be honest, for all I know this specific issue may have already been addressed by upstream. John -- "I am on a drug, its called 'Charlie Sheen'.

Thanks John. The IUS repository looks really good (or reliable). It seems that they have also used the same type of naming convention used by Redhat for php53 with the addition of i or whatever. This is pretty nice for adding and removing packages. Unfortunately, I'm thinking that this will cause the same dependency problem as things like php-common won't be found. Yes, I know I 'can' just go do an install of something like SquirrelMail, something we immediately would need, but that would potentially just be the beginning of issues on a shared hosting system. It sounds like I should just sit back and wait for 6 if I want to stay on upstream (and select repos) for package updates. That has been my hard headed decision for many years and in those many years, has proven to save a lot of future grief and eliminated in some cases some additional downtime during compiles. Looks like if my need for PHP53 is absolute, I'll just move that client to the one 'custom' system and they'll just have to understand that there might be a bit more downtime, then move them onto a 6 box once deployed. And yes, PHP has been the one thing that has repeatedly been the dawg with using Redhat. 6 was way late out from upstream and then the promised option in 5 appears to be at least a bit of a smoking gun. -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I guess I don't do either. I often look at a few remote computers from my laptop, and perhaps download a file while editing a document, but that is about all. The question is, which of us is more typical? I was going to say, more typical of CentOS users, but I only run CentOS on two servers, and rarely login to them; I run Fedora on my laptops. > The main downside right now is cost and how big of a disk you can > afford.

For me, having a small SSD on a laptop would be much more inconvenient than any increase in speed. As I said, it all depends which of us is more typical of Linux users. But I'm generally puzzled by the emphasis many people put on speed. Unless one is a gamer, it doesn't seem to me to make much difference if it takes 13 second or 30 seconds to boot up.
