Ok so say you split your work up into computer size loads (not unreasonable).
now half a decade down the line you have various services running various stuff (fileservers, databases, e-mail, im, custom apps etc). Keeping all those old servers running when the tasks could be performed by a far smaller number is wastefull of both physical space (which may be at a premium especilly if your buisness is growing) and electricity (remember in a large building the real cost of electricity fed to your equipment is significantly more than the cost of electricity from your utility because of aircon costs).
merging such systems onto a single OS image could well be either a lot of work or impossible (e.g. they need different operating systems (or versions thereof) or there are multiple instances of the same app on different servers and it doesn't support setting a bind ip and configuration location). Moving them to a VM is likely to be far simpler.
from what i can gather recent versions of workstation (i've only used old versions so i dunno how true this is) have some desktop user (e.g. software devloper/tester) orientated features that server doesn't.
it seems vmware is trying to set up a free taster product and a better premium product in both client and server categories. In the desktop space player is the taster product and workstation is the premium product. In the server space server is the taster product and ESX is the premimum product.
is that spreadsheets blur the lines between program (it does something), data store (it stores data), and report (it formats the data for printing) in such a way that someone eliminating unwated stuff from the report (say to make a printout neater) can in the process screw up the program.
Exactly correct. In fact, you can see it even on the distribution lines in this part of the country (upstate NY). During the summer, when a lot of power is being drawn to run air conditioners and pool pumps, and the ambient temperature is high, the distribution lags sag a fair bit. Typically nothing dangerous, but definitely noticeable. Look at that same line during the bone-chilling days in January, and you will see the very same line as taut as a piano string. yeah in hot areas (areas where domestic aircon is the norm) you get a double whammy, more self heating AND higher ambient temperature.
on the other hand in cold areas (like here in britan) you tend to get the power peaks in cold weather where they are somewhat made up for by the lower ambiant temperatures.
i belive generally they fill up with water from the supply (both hot and cold connections) and then heat up the last bit to the temperature required (british washing machines pretty much require a dedicated 13A socket giving them 3KW of total power to play with).
iirc generally they will work if you only connect a cold supply but will spend a lot of time heating up to the required temperature.
even if they do the only way they will be easy to install is if they are specifically taylord to one release of one distro.
for example:
kernel modules have to be built against the source of the running kernel, this may not even be installed by default and even when it is where its installed will almost certainly depend on the distro (this ones probabblly the biggest issue).
different distros have configuration files in different places, make different use of include files, sometimes use totally different apps for the same thing and generally make automatic modification hard for any tool thats not intended for the disto. Hell even the layout of/dev varies significantly.
geeks who build/repair computers will know the name (asus being one of the more respected ones afaict) but the general public don't. Yet i'd imagine there are very few who are even mildly computer litrate who haven't heared of IBM or apple.
You're confused because you apparently have only seen Windows pre-installed. Installing it by hand is a major undertaking that involves significant text-mode interactions.
having installed both windows and linux i can say that command line use during the actual installation is fairly minimal, in the 9x days you typically ended up loading fdisk format and the setup program from a dos prompt. Nowadays you don't even have to do that.
Some linux distros go into a graphical mode earlier than win2K/XP setup does but i really don't see any difference in ease of use between a text mode menu and a graphics mode menu.
The differences come after initial setup when you are trying to get the machine up to full functionality. In windows most stuff will need manufacturers drivers but provided you have the CDs to hand they are easy to install. In linux most stuff works out of the box but anything that doesn't is often a major undertaking involveing a lot of work at the command line.
fact is a large portion of the public don't care about the difference between a lossless copy of a CD and a 128K mp3. or they wan't to use it on a portable player with small headphones where it won't make any bloody difference anyway.
also much of the point of services like itunes and allofmp3 is you only purchase what you wan't not the filler you are forced to.
The direct benifits (if any) from dragging one person through the courts and ruining thier life aren't worth the cost of doing it and criminal charges for filesharing clients seems quite unlikely.
so the only reason to take individual filesharers to court is as a scare tactic, it works to some extent but to have a significant effect on piracy they would really have to significantly increase the chances of getting into trouble.
breaking down the networks used for piracy on the other hand will make life harder for pirates who will have to keep finding new good networks and maybe some will give up in the process.
and HTTP can perform file transfers just fine not to mention its far more firewall friendly, seperate control and data connections?! wtf were ftps designers thinking
and for admin stuff it also has the problem of no encryption.
imo though there needs to be an advertised purpose component to it as well.
if you use a consumer level OS in your aircrafts critical control systems i don't belive the vendor of that OS should be responsible for your mis-use of thier software.
of which IMAP arguably does a better job at, but it's moreso for features rather than the problems mentioned in the article offtopic but pop and imap are imo different tools for different uses,
imap is a heavyweight remote mailbox protcol for those who keep thier mail on the server. POP is a lightweight protocol for doing a pull from one mailbox to another (rather than the push of SMTP).
yes your taking a usefull approximation to extreme conditions and screaming when it gives the wrong result.
if you can get your entire problem (or at least a peice that can be split with little communication need) onto one machine thats going to outweigh almost everything else as network is replaced by motherboard interconnects.
but if you put that four cpu machine into a larger cluster all its CPUs are going to be competing for the interface linking it to the cluster.
certificates have a built in expiry date, the cynical would say this is part of a money grab, the less cynical would say its to stop certs with no longer acceptable encryption levels remaining in use and to reduce the lifetime of a stolen key.
Either way if its just a community site or something i'd ignore it but if it was a merchant or worse a bank i'd be worrying about how well they are keeping thier house in order if they let thier SSL certs expire.
it doesn't excuse it but it does increase the temptation.
when your losing in life anyway (can't afford a decent life for you and your family) taking some risks to boost your income looks a lot more attractive than if you are already making a decent wage and comfortablly meeting your bills and having some disposable income each month
so I get pissed off every time we have to buy more RAM for those boxes would it be cheaper just to replace some of them and use the ram from those you scrap to upgrade the others?
how much does a new motherboard/CPU of comparable performance cost nowadays anyway?
you aren't going to take the partial pressure of oxygen much below that in normal air and still have the human body function correctly. You can of course decrease the pressure and increase the oxygen richness though that brings its own problems (mainly that you can't easilly launch something from earth with a reduced pressure atnosphere inside, appollo got arround this by launching on STP oxygen but STP oxygen is NASTY) and probablly won't effect the bodys oxygen useage much.

"various services running" should have been "various servers running"

i'd guess most likely they are completely disabling activex in IE
IE only supports AJAX through activex (this is changing in version 7 but that won't be widely deployed for a while).
note that in excel you can write functions in VBA and use them as worksheet functions.

it may be capable of it but afaict most clients don't really allow you to use it that way, outlook certainly doesn't.
pop can also leave messages on the server though again most clients don't really support using it that way.
what would you do differently then?
sure talking text has its disadvantages but it also makes debugging far far easier to be able to talk the protocol manually if you have to.
and HTTP can perform file transfers just fine
not to mention its far more firewall friendly, seperate control and data connections?! wtf were ftps designers thinking
and for admin stuff it also has the problem of no encryption.
