2/20 Why flash ram will get you into trouble, in the long run:
http://www.pcper.com/article.php?aid=669
This is worse than over-clocking your computer. There's data
involved.
\_ What's your point? That flash supports a fairly limited number of
write cycles? We knew that already.
\- I am not the OP but dont think you're inquiry is very
thoughtful. This may be another case of "physical difference"
[between rotating mag storage and memory cell storage] cant
be abstracted away by software emulation" [in this case
focusing on the write/erase asymmetry]. An older example of
this with another hyped technology was ATM emulation of
Ethernet and the problem of doing broadcasts. |

12/2 1000 lines about Vmware. have you even tried to install
Vmware 2.0?
\_ if it's about messing around with virtualization at home, I've done
quite a bit of tinkering already with VMWare, VirtualBox, etc.

11/29 I'm experimenting with virtualization, and as a poor college student
I'm wondering what the best alternatives for virtualization are, and
how best to cut my teeth on messing with non-linux platforms (or I
guess interesting stuff on Linux would work too). Right now I've got
FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am
somewhat at a loss as to how to use it. (More details: bridged
networking, disk is a 8GB partition software raid1'ed over 3 disks).
In any case, KVM seems to just 'work', but as the CSUA is planning to
offer VMs soon, I'd like to know if there are better alternatives,
particularly considering that when I put my computer to sleep without
shutting down the guest OS, the computer wouldn't start back up, I had
to cold-boot, and the disk image got corrupted. From what I hear,
VMWare's offering is solid, but the useful administration software is
thousands of dollars. Ideally, free software or something sustainable
without repeated donations of software, and easy to administrate would
be best. Does anyone have suggestions? --toulouse
\_ At my job, we use Vmware 2.0. it is free. i run vms. there
are graphical admin tools. I could buy Vmware ESX, which gets
me I guess better admin tools, better performance vmotion and fail
over.
\_ Someone here works at VMWare and was recruiting 2 years ago.
Calling the VMWare guy! We need a free educational license!
Oh well, he's probably not going to respond until Monday.
Us old farts have kids and family things to go on weekends.
Oh, try this. And yes we use VMWare in our company and it
is really great. You can get snapshots of the machine, run
multiple instances on a single machine (since most machines
are underutilized). Our production servers are also in
VMWare for superior bug isolation and debuggability:
http://www.vmware.com/partners/academic
\_ What, you mean CSUA alums have lives? Unthinkable! --toulouse
\_ Isn't VMWare Server free? That's what we use in our company.
--- !OP
\_ I don't recall the details, but while the server itself is
free, I think the administration interface is expensive.
Feel free to correct me on this. --toulouse
\_ Here's the deal. Vmware has two products. The Free Version
(Vmware 2.0) , and Vmware Server ESX ( not free. lots of $$$$ ).
ESX is a different codebase than Vmware 2.0 free. With ESX,
you get better performance, better GUI tools, failover capability,
and the ability to magically move your VMs from machine to machine.\
freely available Vmware 2.0 has a gui too.
and the ability to magically move your VMs from machine to machine.

\_ VirtualBox?
\_ virtualbox is a sun thing. its not vmware. it
has its strengths and weaknesses
\_ ESXi, the hypervisor, is actually free, it seems, but the magical
admin tools are a part of ESX and not ESXi:
http://www.vmware.com/products/esxi
Anyways. Paging VMWare employees...anyone here?
--Andy
Anyways. Paging VMWare employees...anyone here? --toulouse
\_ dude are you running a root name server? Vmware 2.0 is
just fine.
\_ doesn't mean ESX wouldn't be better ;). Ease of admin is a
real concern for us, and besides, if the software is
satisfactory, we might even virtualize soda itself. Given
time, if we got another server with virtualization
extensions, failover would be a large win. As you may have
noticed from recent downtime, Keg's been on the fritz
lately, so uptime's been on our minds. Without failover,
we're back to square one re: evaluating KVM vs VMWare vs
others, hence this thread. Besides, there's an argument to
be made that if we have experience managing the good stuff
here in college it'll be what we're qualified to manage once
we strike out in the real world, and/or the software that we
recommend to our superiors should we get relevant jobs
(which, arguably, a few of us will). --toulouse

\_ I guess. Really, I think Vmware 2.0 is adequate.
There are plenty of cheapass companies out there running
it.
\_ You know, when I was a poor college student, I
wasn't very picky. Seriously, the two may have
different features that you'd need in the enterprise
environment, but are you running an enterprise?
\_ Well, I'm not picky wrt/ using what works for me
(which, as I mentioned before, is KVM), but I
want the CSUA to be a bit more ambitious in its
endeavors, and as they say, shoot high, aim low
(is that the right saying?). Plus, there's the
fact that our vp is not paid, so minimizing the
addition to his workload while offering more
students to members is also a factor. In any
case, I think it'd be prudent for us to see if a
software donation is feasible, and if not, what
our other options are then. This is something
that can wait a bit, as we're waiting on those
core i7's. --toulouse
\- (80cols ... reformatted)
\_ well if this is about the CSUA rather than
personal edification, how about first dealing
with the frequent crashes/outages of soda ...
or is this an attempt to do so? [this seems
odd to me, but whatever]. second, to abuse
a quote a bit, "software is the continuation of
policy by other means" ... "what [csua] problem
are you trying to solve" [via this software, via
donation campaign/new hardware etc]. BTW, with
regard to giving csua people experience with
expensive tools, i actually think part of the
reason a lot of ex-csua people have been
successful systems people is they resorted
to hacking togethe things and thus understanding
how they work under the hood, rather than
throwing money at the problem [hardware and
softwarewise] ... i'm not saying you should say
solve all problems that way ... like if you need
disk space today, just go buy a cheap disk
rather than scrounging, but just the observation
in the past, some of this hacking to debug
something or getting it to work (and much of
this was pre-google) served people well.
\_ Yep, real learning comes as part of the
struggle. In some sense, it would be better
for students not to primarily have experience
with enterprise software packages since
these are made "easy to use" for the corporate
drones who wouldn't survive if they had to
have any real degree of understanding of how
the system actually works.
\_ Well, the learning I was looking for when
putting the idea forward (since I suggested
it) was geared towards people exposing
themselves to different OS'es and playing with
root in a sandbox. This is the problem I want
to solve, not training people in enterprise
applications. Also, soda hasn't been crashing
-- it's been keg, which serves our LDAP, that
(as I said before) has been on the fritz. If
keg goes down, then logging in does not work.
Politburo intends to buy a new server for
this; however since the Core i7 is coming out
we don't want a purchase now to be obsolete
upon arrival. We have the opportunity now to
solve two problems at once: allow interested
members access to their own personal VMs, and
increase stability of our servers. We can most
definitely do without failover, but then the
uptime problem isn't as completely solved.
The idea of getting students experienced in
adminning VMWare may be of low priority for
the CSUA as a whole; on the other hand, it is
(IMO) the strongest argument to be made to
VMWare.
In summary (and in my opinion) -- high
priorities are increasing uptime and developing
skills with adminning systems.
low priorities are developing VMWare admin
skills and...well, steven should be coming on
soon to offer his opinion. --toulouse
\_ Can't you request a free license for VI3 from VMware at
http://www.vmware.com/partners/academic
\_ You could try virtual box from Sun, it is free and runs many x86
OSes:
http://www.virtualbox.org
http://www.virtualbox.org/wiki/Guest_OSes
Re VMWare - Fusion for OSX is very nice and quite affordable (I've
seen it on sale recently for as little as $30). It has GUI admin
tools and the unified mode makes using windows apps almost like
using native OSX apps.
I'm currently using Fusion to run WinXP and Ubuntu and have used
it in the past to run Solaris x86 and FreeBSD as well. I usually
run XP and OSX concurrently and haven't ever had any problems with
the XP VM getting corrupted when I sleep my iMac. If you have a Mac
I'd recommend getting it.
\_ I don't think you understand what he's trying to do.
\_ Maybe I misunderstood, but isn't part of what he is trying to
do is becoming more familiar with non-linux systems ("I'm
wondering ... how best to cut my teeth on messing with non-
linux platforms"). If he has a mac, Fusion is a good way to
accomplish this - it can run Solaris, Linux, *BSD, Windows,
&c. and will help him get a feel for those systems. Virtual
Box, while not as nice as Fusion (at least on Mac), is a
free way to accomplish the same.
\_ These are two different objectives. I'm talking about setting
up VMs as a service for CSUA so we can consolidate our machines
while maintaining some sort of security and OS diversity (linux
+ BSD at least) If toulouse wants to learn about
virtualization
of course Fusion is a good option (he does have a mac), but
that's a different aim. --Steven

\_ Hey guys - Steven here
Thought I'd weigh in on the situation. The recent outages have
indeed been because Keg has been crashing (as presumably toulosue
pointed out) and I'm fairly sure it's a hardware issue. We're
simply running too much IO through the (decently old) system
and parts of it have already failed (we've lost one of the
ethernet controllers already) so I'm willing to blame the system
instead of the software. That said, we're hoping to buy a massively
cool system when Core i7 Xeons come out (thinking 16+ cores). At
that point it seems reasonable to look at virtualization. I've
used Fusion and Virtualbox in the past, so I'm not new to it
by any means - but one of the requirements is that it's easy to
admin/use. The issue here is the host OS - I'd like to use ZFS for
the disk array we'd need to have to back all this. Linux doesn't
seem to have a very good filesystem for this sort of thing - ext4
isn't stable, btrfs is still even further off, ext3/LVM is pretty
hacky, JFS/XFS really really need battery backups to not lose data,
and reiserfs's future is very unstable.
ZFS offers ZVOLs which seem to be perfect for giving out virtual
partitions. Right now we have Soda mounting off of Keg via NFS
which as you may have noticed is a serious performance and stability
problem, so I'd prefer not to go with NFS again. The network FSes
out there all seem to suck in one way or another, so local storage
(especially for something like this) seems to be a must.
Since that limits us to using FreeBSD or OpenSolaris as a host OS
\_ or OSX, see:
http://preview.tinyurl.com/5zo987
[developer.apple.com - zfs(8)]
\_ We're not rich enough to buy a
Mac Pro/XServe :(
(unless Linux ends up having a decent fs by the time we actually
get this running). Virtualbox doesn't seem to work well on FreeBSD
(as in not at all) and Xen seems to not play nicely with either
BSD or Solaris as a dom0. VMWare won't run on BSD either - not
sure about Solaris, which is why I was looking at ESX. The problem
with ESX is that it runs on only about 3 supported hardware
configurations which are pretty hard to build on our budget.
Discuss?
I'll hang around and maybe get into this whole motd thing ;)
\_ Virtual Box on OpenSolaris w/ ZFS sounds like it would probably
work. I used to know some OpenSolaris people when I was at sun,
and could probably put you in touch with them if you run into
problems. -ex-Sun
\_ That'd be neat, I'll do so if we go that route and have
troubles |

I just tried it out with XP and Vista as the guest OS and it seems as

6/10 Is there a handy guide to virtualizing an already running

\_ this probably isn't the "right" way, but I have many times
just run rsync. ("rsync -vpa root@oldbox:/ /") on a fresh virtual
image. Just make sure the partitions are the same on the virt disk
as on the real disk and if you are using a new udev, kill the info
in /etc/udev/rules.d/z25_persistent-net.rules before rebooting the
virt). I have not had any problems doing this.
\_ I attended a talk where I *think* VMware mentioned a tool they
provide to do this. Check their web site.

6/8 hey nerds, Virtualbox is totally awesome. My host OS is
current ubuntu, I'm running Windows as my guestos, I can transfer
files, copy/paste, all of that crap
\_ Cool, I was thinking of looking into this soon. How well does
it work? Can I run most windows programs pretty well? ActiveX?
Games?
\_ You might be confusing running a vm with 'wine' . -op
\_ It runs all your windows programs... if your guest OS is windows.
\_ Sure, but there could theoretically be issues with drivers.
Say the video drivers don't interface properly so you can't
play 3D games. Or performance is too poor.
\_ Running your 3D games in a VM will never work very well.
\_ How does it compare to vmware workstation?

12/3 Has anyone seen this VMware problem before? When I have one or two
VM session running, Task Manager on my host machine shows that the
vmware-vmx.exe processes uses 0% CPU time when the VMs are idle.
However, when I have more sesssions (maybe 4 or more) running, Task
Manager shows that each of the vmware-vmx.exe processes is using
10-20% CPU time even though all the VMs are idle. This eats up CPU
cycles from my other processes. I'm using VMware Server 1.0.3. I
have a HyperThread CPU and the "Number of processors" setting for my
VMs are set to 2. Thx.
\_ What do you think of VMWare in general? We are evaluating it now
for possible purchase.
\_ What are you going to use it for?
\_ Almost everything. Production servers, dev and test
environment. Probably not for the database servers though.
Does that answer your question?
\_ No. It doesn't. What are you hoping to gain by using
VMWare?
\_ Server consolidation, better ability to manage
dev and test environments, hopefully a better DR plan.
\_ Sounds like VMware might work for you then. I've
used VMware since version 3 and I've been pretty
happy with it. I don't know if I'd transition
all of my hosts to VMs just yet, but it excels
in meeting the needs you have.
\_ I've used VMware for about 4 years with debian as the host OS.
it is fantastic. on my new intel macbook i use VMware Fusion.
\_ Does TM say if this if kernel or user time? Are you swapping?
\_ Kernel time. No the host machine is not swapping. It has 2GB
RAM, and the Commit Charge Total is around 1.8GB. |

8/31 is this cooler than say kickstart or FAI or whatever
the current cool way to admin 10000 machines is?:
http://code.google.com/p/ganeti
\_ This seems to be focused on managing Xen VMs and require
the host to have Xen already installed. I'm still a fan
of cfengine, though it won't do the initial install. But
I have setup kickstart to just install cfengine at the end
of the install and have cfengine take care of most of the
configurations.
\_ Is it a lot of overhead to have Xen running on every machine?
\_ Why not use System Imager?
\_ System Imager, as it was last time I looked, is fine if
you're managing bunch of machines with *identical*
configurations. cfengine is more flexible and can work
across multiple platforms as well. Also changing a
configuration doesn't involve re-imaging the whole machine.
\_ System Imager is more flexible than that. You can
propagate just the changes. I much prefer SI to
Kickstart. If you want to use cfEngine on top of that
then fine, but cfEngine solves a (mostly) different
problem. |

workstation
give me? Their products page should have a big table listing all
the major features and bullets showing which product has what. I
can't find that. It's a confusing products page. Thanks.
\_ Workstation has some nice features like being able to save multiple
snapshots and such which is good for developers. The latest
version of Workstation also has better hardware support and some
other goodies. There's also VMWare Server, which is a free product
that can let you create VMs as well. VMWare Server interface is
limited to one snapshot per VM(though internally, it does keep
previous snapshots in a linear fashion. Workstation may offer
snapshotting in non-linear states - I've never used the Workstation
product when snapshots were in place.) |

to tweak if your OS/apps aren't happy.
\_ Don't have time to setup and learn about virtual machines? Don't

10/30 Can a hyper-threading CPU run two threads in two separate apps at the
same time? How does it handle the two different virtual memory
mapping? If I mostly run processes where only one thread is active,
(e.g. compilation, SETI@home in background, VirtualPC or VMware
instances), does hyper-threading help or hurt performance? (I know I
really should profile to find out, but I want to know the theoretical
answer.) Thx.
\_ They get interleaved the same as anything else. Go look up Intel's
*very* well written white papers on the topic. You won't find
better answers anywhere else.
\_ Intel has published several white papers on their site that explain
in easily read English exactly how HT works. You are unlikely to
find a better explanation anywhere else. Kudos to their doc
writers on that one.
\_ Virtual memory is not an issue. As to the rest, unless you are
doing stuff where getting about 1 percent more out of your cpu
matters, don't worry about it. Hyperthreading has a bit of
performance hit in most cases but makes up for it by making
the computer much more responsive at high load. In a gui environment
this makes you computer feel zippier and is worth the performance
cost.
\_ Actually, it makes the computer less responsive under a high
load. Why? Because the CPU is trying to execute more
processes than it has processors. Try this experiment: Run
three jobs with a nice level of 20. Then run one interactive
job. See how (un)responsive it is? Now turn off HT and
repeat the experiment. I guarantee you it will be more
responsive in the latter case. |

what options takes a while if you don't know what you're

1/10 VMWare GSX is most similar to VMWare Workstation. GSX allows the
console to be viewed remotely. GSX does require IIS to be installed
to handle the web component on Windows, or apache on *nix. ESX is an
OS unto itself... it runs on a modified Linux kernel, and all virtual
machines use a different file format than Workstation / GSX. Also,
installation and administration of VMs is always done via web browser
or remote client, and not directly at the server's interface. The file
system it uses is unique as well, called VMFS. All virtual machines
must be created on a VMFS-formatted partition, and VMFS will not
install on IDE drives in version 2.5 (never tested that in v2, so IDE
drives may work, or may not). For more info see below:

6/17 I'm trying to use VMware Tools to "shrink" my Fedora Core 3 partition.
Note that VMware "shrink" means to claim space not used by the
vm so that the host will have extra space. This is important
because when you create a big file in VMware and then delete it,
the host still keeps the big file and wastes space. My problem is
that VMware tool only recognizes /boot as something that is
shrinkable while it doesn't know anything about /.

4/14 I'm a bit baffled by VMWare. Inside the VM, the reported disk usage
is 2G. But outside the VM, the disk size is 5.6G even though I already
1) defraged inside the VM and 2) defraged using VMware. Why is that?
\_ You can specifiy whether you want to allocate a huge disk or only
allocate as it's used. Which did you choose?
\_ VMWare has a checkpointed file system. Good for "rollback" to
known state. Not frags, but history makes the space larger than
visible in the embedded OS. I believe this is an option in the
vmware setup / config.
\_ I found the answer. You have to go to VMWare Tools inside your VM,
and then select Shrink, Prepare to shrink, and then Shrink. |

4/1 VMWare gurus, please help. I've configured my VMWare on my laptop and
everything seems fine at first until I unplug my eth100 and wireless.
All of a sudden, my host system (XP) and VM (Linux) can no longer
reach each other. How do you configure it so that it doesn't rely
on having a connection? -ok thx
\_ Well, how is the virtual NIC configured for the VM? If you're
using host-only or NAT, then it should work fine. If bridged,
then it's not surprising if it doesn't work, especially if
you're using DHCP.
\_ I'm using automatic bridging, and by default it already
selected VMnet2 and VMnet8. It gave me subnet
192.168.175.0 for vmnet2 and 192.168.117.0 for vmnet8.
Is there something I have to do?
\_ What do you mean "it automatically selected VMnet2 and
VMnet8"? What is "it"? Selected them when? How did "it"
select both? And how is your host configured? And BTW,
VMware does have support forums on their website...
\_ I didn't configure ANYTHING, it's the way it is when I
installed it. What do I do? Thanks. -pp
\_ Uh, I thought I made it clear already that you can
try setting the VM to use host-only or NAT networking.
You still haven't said whether your host OS uses DHCP
or not.
\_ Yes, host OS uses DHCP, what difference is that
gonna make? If it's not DHCP it renders my laptop
portability to "pain in the ass to reconfig"
\_ Well, I don't know what Windows does when it
can't obtain a DHCP address, but it doesn't
surprise me that it would suddenly become
unaddressable. Anyway, you always could
try adding a second virtual NIC to your VM
that uses host-only networking. I'm not sure
if that would work; I've never been in your
situation. If not, then ask on VMware's
support forums. |

\_ IBM mainframes did do virtualization back in the day, but
otherwise, no.
\_ they still do today; it's the basis of their linux
server consolidation story.
\_ the IBM VM is more like Zen, in that the OS is written to
an appropriate virtual machine rather than trying to virtualize
a hardware platform not designed for it. they also have
more virtualizable hardware because of this legacy |

1/28 Who here works at VMWare? I have a suggestion for you so that maybe
you can talk to a marketing dude or something. I think VMWare is one
of the coolest products out there. How about this for marketing.
Give free copies to academia, they really need it for say, OS projects
and what not. Also, give lots of academic discount to students
since many of them are Linux/Win dual boot users, and since quite a
few of them are kernel hackers it'd surely suck them into using your
products. Once you get the kids addicted, they'll keep coming back.
Mr. Evil M$ Gates understood this decades ago and gave free copies
of WinCrap stuff to academia, and look how well he's doing.
\_ Giving software to academia is not free. The tax break can be
extremely valueble. I've seen some pretty shady stuff with
software donations. Does a company really deserve a 2 million
dollar tax writeoff for donating software that isn't really needed?
Maybe, but it's definitely not "free."
\_ Doesn't VMware have academic pricing?
\_ That's like the M$'s strategy of settling the anti-trust lawsuits.
\_ VMware has been profitable for quite some time. I don't think
they need your help.
\_ cool because I really enjoy my free warez copy and I love the
fact that it's so easy to get serial numbers on the internet

1/13 VMware performance tuning *experts*, I have a question for you.
Suppose you don't pre-allocate entire 80G of HD during VMware
configuration. You have an option of limiting file sizes to 2G
or have a file that can grow up to 80G. What are some
advantages/disadvantages of limiting VMware file sizes to 2G?
Say you have one big file that eventually grows close to 80G,
wouldn't it be hard to defragment it on the host machine? The
advantage of 1 big contiguous file I suppose is performance, but
suppose you don't have enough space to defrag it, then wouldn't
that option be useless in the first place? |

2) communicate between the two machines? I can ping WinXPsp1
from WinXPsp2, but not the other way around.
3) Say I install VNC on WinXPsp1, how can I make it so that
VNC ports go directly to it, instead of the host machine?
Thanks for any help.
\_ What do you mean 'on top of'? You are running WinXPsp2 natively
and WinXPsp1 in the VM?

12/21 What are some core differences between a simulator, an emulator, and
a virtual machine?
\_ Simulator: Model the whole thing by itself; collect results.
Emulator: Model one part; hook it up to something else.
Or, run one OS on another OS.
Virtual machine: A computer inside a computer.
Or, a VM like the Java VM.
\_ Simulator: Models something by mimicry.
Emulator: Interprets instructions for one architecture to another.
Virtual machine: A pretty generic term. There's VM in the sense
of Java VMs (which represents a virtual hardware architecture)
or in the VMware sense, in which most instructions aren't
interpreted).
\_ so the Crusoe chip (on-demand translation of x86 instruction set
to another) is... emulation? What about VMWare, is that also
emulation? What about simulators, what are some well known and
commonly used simulators out there? Does VirtualPC (for Macs)
count as simulator because you're not doing emulation?
\_ VMware is partly emulation (for the virtual devices) but
for the most part is virtualization. VirtualPC for Macs is
an emulator; it's interpreting x86 binaries. Won't comment
on the Crusoe.
\_ What's the context?
\_ In some contexts, a simulator processes the simulation of an actual
design, while an emulator accomplishes the same result at a higher
level. A VM is a software computer environment for a program (a
computer implemented as a program that runs on another computer). |

11/9 I have two versions of MSIE 6.0.2800.1106. One is running inside a

When I run a google query: http://www.google.com/search?q=canada.ca
They get slightly different results. What's the best way to figure
out why this would be? Perhaps a way to capture the request?
\_ Maybe you're just hitting different google mirrors, and their
indices aren't quite in sync? You could test this by using an
explicit IP address like 216.239.57.99 instead of "google.com".
\_ netcat is good for this. Use 'netcat -L <DEAD>athos.989studios.com<DEAD>:10070
-p 8000 -o logfile' listens at port 8000 on the local machine, logs
to the file "logfile", and forwards the result to athos port 10070.
\_ Does Google incorporate randomness in its search result when, say,
there's a tie in relevancy?
\_ the above will do the net capture but i think the answer lies more
in how google works than your browser. packet captures will only
tell you what you already know: you're getting difference responses
back from google. |

6/20 I have an OS question. Most programs make use of shared
libraries and use a dynamic link loader to relocate branch
targets at run-time. The problem is that if you have
multiple copies of, say, emacs running under their own
user space wouldn't those relocated addresses (either relative
or absolute) conflict under each process? For example, if
multiple programs were using OpenGL they would create virtual
memory entries for libGL.so in their own process space. The
location of libGL within this process differs from program to
program so if libGL calls libm.so the dynamic link loader will
place that library in a different location for each process
and the branch targets under one process won't correspond to
those of the other.
\_ The shared bits are mapped to the same virtual addresses in
each address space.
\_ Not sure what you're asking. But only the text portion of
the shared lib is shared amongst the different processes. All
processes that need to use libGL.so have addresses that point to
just one copy of the text portion of libGL.so. It's the OS's
job to keep the program counter and the VM straight. Why would
there be any conflict?
\_ That's the problem. If you only have one copy of libGL.so
in memory there would be a conflict in the outgoing branches
from libGL. For example, if we were calling glVertex
within libGl. That function would have a jump an link
to another absolute address to the libm math library. The
dynamic link loader is responsible for resolving the branch
addresses. The problem is that if one user was running
Quake while another person was running Doom or something
like that then the jump target addresses would be different.
Let's just say, for example, that glVertex called the pow
function:
Quake Doom
----- ----
0x00000000 main 0x00000000 main
0x00003fff end of quake 0x00001fff end of doom
0x00004000 libGL 0x00002000 libGL
0x00005000 libm 0x00003000 libm
0x00005040 pow() 0x00003040 pow()
If we were to have a jump and link to the pow() function
then the addresses would be different in both copies of
libGL.
\_ Also, most, if not all, shared libraries are compiled to be
position-independent. |

10/9 Anyone know of any alternatives for vmware?
\_ Boochs or Wine
\_ What's wrong with VMware? |

9/28 Anyone heard of vmware? Is it good?
\_ my friend just joined vmware as dir of product marketing...his
judgment has been good in the past...
\_ Its pretty good as long as you have a fast machine (~300 PII
or higher).
\_ It's great for testing out, say, how a webpage loads
under 9xNetscape. However, it's horrible if you want
to send something to a port or anything like that.
Regardless it's the best option; use it, love it.
\_ vmware is good. Get a free evaluation key and try it out.
Too bad it's not free... |

3/02 which term is the most capable? vt100,102,220,ansi...?
\_ Why don't you show of your capabilities, big boy, and help
the rest of us decide.
\_ The TeleVideo 920s they had down in the WEB. Those were the best.
\_ And the handy location of the break key was a stroke of
genius. The keyboard design of the tvi920 was second only
to the old HP keyboards (105 Cory) in pure key placement
masochism.
\_ web TV
\_ whichever one your software emulates. if you have choices,
the larger the vt number, the more it can do, but telling
soda you're on a vt320 will just screw you up if your
software only does vt102
\_ vt100 is almost certainly good enough for just about anything.
for the most part, vt100 = xterm as far as terminal emulation
goes. [niggly idiots, note "for the most part". thank you]
