3/24 Soda is not allowed to connect to agae for Usenet. Which server
should we use?
\_ The campus no longer runs a Usenet server. For class newsgroups,
use news.csua (aka <DEAD>news.berkeley.edu<DEAD>); for others, there's a good

The reason for the failure was
self signed certificate in certificate chain (details)
We have not verified the identity of your server. If you ignore this certificate validation
problem and continue, you could end up connecting to an imposter server.
If the certificate validation failure was expected and permanent you may avoid seeing this
warning message in the future by adding the option
/novalidate-cert
to the name of the folder you attempted to access. In other words, where\

12/7 How many TCP retransmits are too many? Here is what I get:
3594143433 segments received
3760174421 segments send out
3801829561 segments retransmited
\_ rephrase. you can never have too much money. or too little.
what is, is.
\_ You always get a few, but I have a bunch of squid servers that
I just noticed have 500/second, which seems really high to me.
They do about 20MB/sec at peak so this is a retransmit every
40K? This is kind of hard to believe, because they are working
fine.
More details have been requested so here they are:
Each server has apache and squid installed and serves about 10M
requests/day out of memory in 5ms or less. They are configured
as memory only squid servers. They are middle tier caching
servers, sitting between an application layer and an API.
They have 1Gb/sec uplinks to shared switches, which each have
1 Gb uplinks to the core routers. No other servers on the
switches are showing this behaviour and the switches themselves
are not overloaded. Further investigation shows that 99% of
the connections on the servers are sitting in TIME_WAIT, which
I actually think is the cause of these retrans. I am still trying
to figure out who is rudely dropping all their connections to
these servers, but it is hard, since all traffic is through a load
balancer (NetScaler). |

11/24 What is the best 25-32" monitor out there? I am ready to upgrade
my 9 year old CRT. -ausman
\_ How much money are you willing to spend, and how good do you
really need it to be good? Are you willing to pay $900 for the
industry standard monitor used by graphics artists, or are you
so cheap that you'll only want to pay up $400 for something that
is good enough for coding and checking email? $900 or $400?
I've uploaded an Apple LED Cinema Display 24" vs. Dell Ultrasharp
2408WFP, pixel-to-pixel comparisons for you monitor pixel peepers
out there. Does it mean anything? If you're not a pixel peeper, no.
link:bit.ly/DellVsApplePixel
\_ I spent $1k on my last one and will probably spend about that
this time. I might spend more if I really thought it was worth
it, but not $15k. If I can get really good quality for less,
I would be happy to spend less, but I doubt that is true.
I like to buy good things and then use them for a long time. -a
\_ "Best" is subjective. And sorry, I have no recommendation in
the 25-32" range. For 24.1", Eizo CG243W.
\_ $2200 eh? Do you have one? Is it worth it?
\_ I have a really old L565 and somewhat outdated S2410W
(paid around $1700). Zero complaints about L565. S2410W
uses Samsung's PVA panel, and I'm not quite satisfied with
it. CG243W uses the latest NEC IPS panel. If it had RGB
back-light, I'd pay $3000 for one. As is, I'm just very
tempted.
\_ Self correction. Apparently, even CG243W uses LG panel. Where
has all the high-end gone.... Also, the new SX2462W appears to
use the same IPS panel, at much cheaper price, but without
hardware calibration and some other really high-end features.
That might be a reasonably good buy. I'm just going to wait it
out until there's a no-compromise (to me anyway) model.
\_ Additional information. Looks like CG232W is the one using NEC
panel. It's actually smaller (22.5") but has the same resolution.
\_ CG232W has a $15k price tag. That is too much for me.
\_ I hate to sound like an Apple fanboi but when I tried out
the 24" Apple LED Cinema Display, I was completely sold.
Stay away from Dell Ultrasharp 24" unless price is an issue.
Check out http://Amazon.com user reviews.
\_ Curious why? I have a Dell Ultrasharp 24" and it has been a great
solid monitor, used for over 2 years now. -ERic
\_ It's a perfectly fine monitor for its price. It has MORE
features than the Apple Cinema display, by leaps and bounds
AND you can buy several Dells for the price of one Cinema
Display. Spec-wise, it is brighter, more contrast, yadda
yadda yadda. However, not everything is about features.
There's a reason why most graphic artists still prefer the
Mac-- better rendition of colors, and the color-balance
is simply calibrated very well. I wrote a review on
Amazon about this, and it used to be on the top review
(10/11 people thought it was useful). I just went back and
found out my review is now shifted to the bottom, WTF! They
also took out a near microscopic comparison of
pixels which I uploaded without giving me any warning!
FU Amazon. Anyways here it is:
link:bit.ly/DellVsApple24
\_ We have a bunch of 24" Dell Ultrasharps at work and some
have failed, but they were replaced under warranty. They
look fine when they are working. The Dell 20" and 30"
seem more reliable. If money was no object I'd go with Apple.
\_ 24" is fine, too. -ausman
\_ I am going to get the Apple 24" thanks for all your advice. -ausman |

12/31 SOMEONE PLEASE FIX KEG! Why does it keep crashing?

\_ How about a backup LDAP server? I don't need files as much

11/12 What is diff between SAN and NAS?
\_ NAS=Network Attached Storage. Appliance which provides disk
to servers/clients via file-based protocols (NFS, CIFS, iSCSI).
SAN=Storage Area Netwoork. Provides direct fiber connections from
multiple servers to a single storage array. -tom
\_ Here is another way to explain It: They're very similar in that
they are both technologies to have storage separate from the
server. However with NAS, the storage protocols run over the
server's normal network interfaces. With SAN they go over
special 'dedicated' storage-only connections, typically fiber.
Furthermore, SAN uses a different storage-optimized protocol,
whereas NAS typically operates over general network protocols
such as IP. -ERic |

\_ We have a demo server that used to crash much too
often. It's named demolition.
\- not http://democratic-party.foo.com?
\_ Yeah the most logical is boring old sequentially-numbered
codes involving machine location and type. My company scrapped
our old "fun" names (the Linux boxes were all something to do
with cold/winter/penguins, the Suns were things involving
suns/stars/hot, although we also had fish like halibut, not sure
what that referenced. But with blade servers they wanted the name
to tell the location. They are incompetent anyway though.
\_ The problem with the location in the name is what happens
when it moves? I cannot stand names like: sparc34_b202_eng24
\_ Four-letter words.
\_ Four-letter dirty words for body parts: cunt, dick, cock, boob.
What else?
\_ My first company used element names, and they let the engineers pick
the elements. So people usually pick names or symbols that were
close to their names.
\_ server location / OS / function and a number. For sites with
zillions of non-unique systems. E.g sfouxsvr00123
\_ use DNS delegation properly. http://uxsvr123.sfo.yourcompany.com
\_ A "good" naming scheme will use this AND have loc codes
in the hostname, so it's also visible in NIS and ADS. Most
sensible name setups use a combination of "logical" names
and CNAMEs. -John

12/20 Is soda connected to an ntp server? The clock is about 25 seconds
behind.
\_ Thanks for pointing this out. It turned out our old /etc/rc.conf
didn't specify the full path to ntpd, and so the new FreeBSD rc
files were refusing to start it. It should be working now. You
can run "ntpq -p" to see which NTP servers (if any) soda is
connected to, and how far off our time is from theirs -- please
let me know if you ever notice it's not working. --mconst
\_ I just checked, and ntpd wasn't running; I've restarted it.

\_ Actually, soda's clock looks fine. Maybe it's you.
\_ It's fine now, but was slow earlier. You'll have to take my
word for it. |

11/2 Does anyone still use VM (Vmail) in Emacs? I reluctantly switched to
Outlook 4 yrs ago when I switched job, and I haven't used VM since
then.
\_ Used it until ~1 year ago. It unfortunately hasn't been updated
for several years. It's really solid for what it does, but it
doesn't do IMAP. I switched to the similar "Wanderlust" which
does support IMAP and haven't looked back.
\_ In the VM 7.19 from http://www.wonderworks.com/vm there is an
vm-imap.el dated 5/30/2003.
\_ VM's IMAP support is marginal. You can pretty much use it
like POP to fetch mail, but you can't do things like
disconnected operation etc. ... if you need to use it just
like POP because your server only supports IMAP not POP,
it's fine, but if you need to do server synching, marks,
disconnected operation, etc., VM is not your bag. -pp |

8/18 Hey Ilyas. Re: Intelligent Design. Please prove that P(C)<0.5. For
extra credit prove P(C) << 0.5. |
| 2005/8/10-13 [Computer/HW] UID:39084 Activity:kinda low |
8/10 The thread below has digressed into wikipedia ramblings, so I'll ask
here. I read the essay "Intelligent Design: The Scientific Alternative
to Evolution"
(found here: http://www.intelligentdesignnetwork.org/publications.htm
this weekend trying to figure out what ID proponents are actually
saying. From reading this I found that the authors were making
strawman arguments against evolution and didn't appear to understand
physical science or probability. Have you read this essay? Do any ID
proponents ever address the weak anthropic principle? Is the 10^-150
probability the number they use in general to show something as
unreasonably improbable? -emarkp
\_ Math is hard. Big numbers are scary. Someone must have done it.
\_ I don't understand what the weak anthropic principle is supposed to
explain. I think 'cosmological constant tuning' needs an answer.
On a somewhat related note, I read an article somewhere that some
experimental data shows that possibly some constants aren't really
constant, and change somewhat as time passes. -- ilyas
\_ In that essay I mentioned (in the section "The Fine Tuning of the
Universe") the authors say: "The force of gravity, the mass of
the electron, the charge of the proton, etc. are specific, real
values. Were they even slightly different from what they are, not
only would life not exist, nothing (of any significance) would
exist." They argue that this specifically suggests design. But
the weak anthropic principle is that if the universe weren't
tuned to life, then we wouldn't be here to observe it. This
directly contradicts their assertion--they should at least
address it. The fact that they don't even mention it is
suspicious at best. -emarkp
\_ It is a counterfactual assertion that does not render the
current state of affairs any less puzzling. Sure, if constants
were different nobody would be there to comment. But someone
IS there to comment, and constants ARE the way they are.
-- ilyas
current state of affairs any less puzzling. Sure, if
constants were different nobody would be there to comment.
But someone IS there to comment, and constants ARE the way
they are. -- ilyas
\_ The point is there is a selecting event (i.e. our
existence) which makes those constants unremarkable. If
we were to observe a universe at random and the constants
were amenable to life, that might be something. But our
universe isn't a random one. It had to have those
constants. -emarkp
\_ What you said is exactly right. Our universe doesn't
seem to be a random one.
\_ Let's imagine a lottery winner pondering what events
lead to his winning ticket. He might say: 'well given
that I _did_ win, the particles in the Universe must
have danced just right so I had to have won. So the
fact that I won (at odds of millions to one) is wholly
unremarkable.' Really, the real reason it's not
remarkable is because millions of people played, so
someone had to have won. In other words, lots of
Universes makes our constant unremarkable. Our
existence does not. -- ilyas
\_ But should the lottery winner conclude that
someone chose him to be the winner? -emarkp
\_ He shouldn't he if knows lots of people
played (parallel Universes). Except in
our case, it's unclear whether it's
cheaper to assume lots of players or
a benign lottery agency. I think this
is best taken 'offline.' -- ilyas
\_ Then your analogy falls on its face.
An unlikely event occurs (Bob wins the
lottery). It doesn't follow that Bob
was chosen by a designer. -emarkp
\_ No, it doesn't follow. I wasn't
saying it does. As I said,
Bob knows lots of people play the
lottery. We don't know whether
lots of people play or whether
someone just decided to give us
the ticket. Not only do we not
know, we don't even know whether
it's more _likely_ lots of people
play, or whether someone gave us
a winning ticket. That's the point,
we have less information than Bob
about our situation. But, just as
in Bob's situation, the anthropic
principle doesn't explain anything,
something else does. My point is,
despite the fact our state of
knowledge is different from Bob's
the two situations are exactly the
same, and in Bob's situation, nobody
invokes the anthropic principle.
So we shouldn't invoke it in our
case either, because our state of
belief shouldn't matter as far as
explanations are concerned. -- ilyas
\_ (1) It's "an"thropic.
(2) It's not invoked to explain
anything. It's invoked to show
that the reasoning that
Life=>special is specious.
-emarkp
\_ Anyways, what is your answer
to the following:
P(C=true,L=true) is low, yet
C=true and L=true. Are you
claiming the above probability
isn't low? If so, why? I
claim it is low on
'maximum entropy' grounds.
Notice how the anthropic
principle cannot be used to
answer this question, although
it is essentially the same:
life + constants -> special.
-- ilyas
\_ I know I'm going to regret
getting back into this,
but if P(C) is the
probability that the
laws of physics create
a universe conducive to
the rise of intelligent
life, C=>L. -tom
\_ No, P(C) is the
probability the constants
assume the values they do
in our Universe. -- ilyas
probability the
constants assume the
values they do in our
Universe. -- ilyas
\_ Same conclusion:
C=>L. -tom
\_ I mean what you say
is true, but I
don't see how this
observation helps.
You can conclude
that P(C) <= P(L),
but how does this
address the
question about
P(C,L)? -- ilyas
\_ I mean what you

\_ The question
about P(C,L)
is not

since life will
arise if the
conditions
exist for it.
The only
relevant
part is
P(C). -tom
_______________________/
Just because C implies L does not mean
P(C) fully determines P(C,L). For that
to happen you would need C iff L.
I don't understand why event implication
means questions about the joint
distribution are not 'meaningful.'
They seem perfectly meaningful (and
puzzling) to me. -- ilyas

-- ilyas
\_ I was right; I regret getting back
into it. -tom
\_ Go pee somewhere else then.
\_ Non sequitur. We know precisely nothing about any
other universes. If you can point to another
universe that we can observe that has the same (or
similar) constants, that would say something. Since
we can't (yet? ever?) observe other universes, we
can't evaluate how random this one is. -emarkp
\_ Let L be an event 'life exists.' Let C be an
an event 'cosmological constants have the values
they hold in our Universe.' Your claim: P(C|L)
is high. My claim: P(C) is low. That P(C|L) is
high does not explain why C is true, though P(C)
is low. P(C|L) is high just because of the way
conditional probability works. To put it another
way, you have to explain why L is true, even
though P(C,L=true) is low. Or if you like, you
can marginalize out C, and reasonably claim
P(L=true) is also low. Or to put it yet another
way, you are offering features of the distribution
P as an explanation for why we have P and not
some other distribution P*. Naturally, that
kind of argument doesn't make sense. -- ilyas
P(L=true) is also low. That's an entirely
symmetric question, and an entirely symmetric
argument would be 'life exists because our
cosmological constants are the way they are.'
At this point, the argument becomes circular, and
I can ask a question about the joint event:
i.e. why is C=true and L=true, though
P(C=true,L=true) is low. Saying 'it's true
because it happened' isn't answering anything.
-- ilyas
\_ No, I don't "have to explain why L is true".
ID says P(C) is low, thus we were designed.
But that doesn't follow. All we know is that
P(C|L) is nonzero, and that P(~C|L) = 0.
Also, we don't actually know that P(C) is low
in the first place. -emarkp
\_ So you are saying that the joint probability
of the constants being what they are, and
life existing is high? How do you figure
that? -- ilyas
\_ No, I'm saying that P(~C|L) appears to be
low (I think my statement that it =0 may
too strong) and that P(C|L) is nonzero.
Everything else is being pulled out of
someone's rear end. -emarkp
\_ Well, you are right that I am making
an assumption that P(C,L) is
reasonably uniform, but this is a
common assumption in science
(see 'maximum entropy'). The anthropic
principle doesn't answer the 'joint
event question.' If you make the
argument that P(C,L) isn't low then
you have to explain why maximum
entropy isn't an appropriate assumption
to make. -- ilyas
(see 'maximum entropy'). The
anthropic principle doesn't answer
the 'joint event question.' If you
make the argument that P(C,L) isn't
low then you have to explain why
maximum entropy isn't an
appropriate assumption to make.
-- ilyas
\_ Dear lord...I actually find this
conversation interesting. I
think I'd better lie down until
it goes away. -mice
\_ (1) Do we know that P(~C|L) = 0? If either
\_ I already retracted
the claim. -emarkp
\_ sorry, just
saw that.
the fundamental constants change over
time (some evid that they might) or
changes in one could be offset by
changes in another (perhaps yet
unknown constant - there is still
that pesky problem of dark matter and
dark energy) then P(~C|L) may not
be zero weaking the case for design.
(2) What exactly is L? Do we really know?
We have only one data point to look
at. Perhaps other arrangements can
give rise to L.
(3) Why is it less probable that ID is
the answer than say some natural
process that produces an infinite
number of universes? If you have
an infinite number of universes
then you will have an infinite
number of universes EXACTLY like
our own.
\_ I find ilyas arguing FOR intelligent design AGAINST
a Mormon to be highly amusing.
\_ Yeah, because people must always argue from an
agenda, and not just follow where the argument
might lead. Grow up. -- ilyas
\_ ilyas, you always have an agenda.
\_ Grow up anonymous troll. -emarkp
\_ My agenda is to legislate Jesus into
your heart. -- ilyas
\_ You're hurting me. -mice
\_ Width of universe compared to age of universe compared to speed
of light taught me that.
