What I want in a new phone

The ability to utilize network services while I am on a call.
That and enough battery power to be online all day.
Also a threaded mail reader
Possibly a web browser that will not actively connect to the network when it is not downloading.

While it is not generally recommended to distract yourself on calls, I don't always follow that advice.

I must say, being able to read my mail and see messages as they come in Is quite useful.
Particularly when people are telling you that they just sent mail that explains everything.

That is afterall the ONLY thing I would be doing.
Not reading blogs or anything like that. No Sir!

Dried and fresh squid...

with black bean suace at Chinatown Express in DC.

prior to that steamed buns (pork)

prior to that the Washington Capitals lost to the Tampabay Lightning 6 to 3

I was feeling adventureous.
Fortunately the squid was good...although I am not sure how I was supposed to eat the big one with chop sticks.
Especially as it was hard to sever the tentacles with only my teeth.

Happy 1st Anniversary

I/We got married a year ago today (14.5 hours from now)

~7 years since the start of the relationship. I would do it all again.

I love you C-, eventhough you will think I am a dork for posting this on a blog (I know that is at least part of why you love me)

My Blogging Methods/Tools

I find that I have developed a method of sorts for posting.

Think, hey I should blog about this
Create a post in an editor
1. Nvu
2. docs.google.com
3. ecto (although I have line break issues that I can't seem to workout)
4. vi
Re-read it to make sure I don't sound like a raving lunatic (unless that is the goal)
Spell check (Firefox 2.0RC3 inline spell check is my favorite new capability)
Publish Post
1. u*blog for treo
1. Found a problem with docs.google.com
  - It appears to have issues with nested lists
  - unless you change back to numbers before you outdent
2. docs.google.com
  - works reasonably well, has issues with time offset
  - writes fairly clean HTML, but posts it without line breaks
  - messing around with entry from multiple locations may break update(re-publish) capability
  - subsequent updates cause the offset problem again
3. ecto
  - great publishing and management tool
  - has problems with time offset (or hard to determine setting that works correctly)
  - Not so hot on getting output to look as expected
    - Losing line breaks unexpectedly
    - RTF convert linebreaks does not appear to work as expected
4. blogs.sun.com (roller)
  - Not fond of any of the built in editors
  - New inline editor is coming, (I followed a link and looked at it, not bad, but now can't find the link)
  - Time on post always as expected :)
  - With Firefox 2.0RC3 inline spellcheck fixes one of my biggest gripes
Read post online to try and make sure I didn't miss anything stupid
Update numerous times to bother people using RSS readers which show updates
Wonder if anyone cares
Manically bounce on the CMD-R to see if my page hit counter is increasing
Check Google Analytics Frequently (even though updates are only once a day)
Occasionally wonder how time of posting affects readership
- Do you get more readers if you post right about break, lunch, after dinner time?
- If you do time your posts does it help more with readers of the b.s.c homepage?
- Do RSS readers increase your page views?
- Should this post be held until morning so as not to be buried?
- Maybe posted now and forward dated
- Running out of things to put in the list
Wonder how many people have read this far and think you are crazy

New Posting/Composing Method?

Publishing test from docs.google.com

Paul posted not too long ago about publishing to blogs.sun.com from docs.google.com.

I am giving it a shot, I have been using ecto for posting and I like it a lot.

However I am less pleased with it's HTML editing, or RTF to HTML as rendered by default
on b.s.c.

So at the moment I am editing HTML in Nvu, which is working well, however I am trying
docs.google.com for HTML editing to see how I like it instead.

Nvu does a great job at HTML editing, but it is more feature rich that I feel that I need
in general for blog posts. I also find that I am online the majority of the time while I am
composing blog entries.

Again it seems that almost everything goes back to the current capacity of my laptop, but
if I can do most(all) of this in a browser interface that I don't hate, why not.

Now to see how timing is working, Paul commented that there were issues with time offsets.

I am having similar problems using Ecto, I thought I had it mostly worked out but instead
every post I publish is way off in time. At some point I will revisit that, but for now I am
logging in and modifying the time for every post.

Well, here goes.

Edit:
well, the post was 6 hours in the future
Now to see if I can publish an update, of if this will go in as a separate post.

Edit 2: Good news and bad news
Good News: "re-publish" acts as an update, not a new post
Bad News: It resets the publish time to now+6 hours

(now to publish again and manually edit the time (again))

Impressions:
It works AND the HTML is not an ugly mess
If it comes down to it I can copy and paste HTML as I was before
I may continue to use docs.google.com to write entries, particularly since etco fetches them after they are posted.

Edit 3: Lame
One thing I just noticed is that the posted HTML (as opposed to the editor displayed HTML)
is posted as all one line. It doesn't hurt the rendering at all, but does make it significantly
harder to read the raw HTML once it is posted.

Ecto downloads the HTML in the same fashion (no linebreaks) which indicates to me that it is
not a local (blogs.sun.com editor) rendering problem.

Also, I can't figure out how to apply tags from inside the docs.google.com editor,
only from the list of documents (and I am not sure how it will work in any case).

Oops:
Broke something, I can't publish updates anymore, the blogs.sun.com url specific
to this entry no longer appears to be valid (some edit on one side or the other has
probably caused it to change) (now updating from ecto)

Edit 'The Last':
The problem that I have with ecto and line breaks persists, the valid looking HTML
is stripping the line breaks. Trying to publish RTF both with local 'convert line breaks' enabled
and disabled results in a nice solid block of text. Back to Taking well formatted HTML
(from Nvu or docs.google.com) and pasting into ecto. Yet another thing to spend time on later
to try and figure out.

Strangely each update I sent with ecto bumped the publish time forward by one hour,
not sure what that is about either.

Blackbox, a couple of pictures and random thoughts

The Blackbox concept is cool, as has been said, I would love to have one at home :)
Although the power bill, even at the reduced consumption from T2000s would be a bit much for my home power budget.
So really, if anyone would like to send me a T2000 and some storage, maybe a 5320 and an x4200

Members of the Grid Engineering Team have been working on this project for a while.
Internally we have had a couple of discussions about how to work Managed Operations into the deployment automatically (everything comes with services now). So what I want now is to get my hands on one operationally.

So the following picture I am posting, not because it was the most technically interesting one that I saw
there were plenty of other technically interesting photos, I liked the lines and the partial reflection of the photographer.

This picture I am posting because...well, seriously. It seems to me that we may be pushing this example just a little.

So can someone tell me who will be hooking up the water?

Here because I figure people might want to see an actual Blackbox

Radio tags spark privacy worries

I recently wrote a parody post where I took some text from a livestock tracking supply company and changed it to talk about people instead of catlle. It was written in response to a BBC article on RFID tagging at airports.

Unveiling the study, EU commissioner Viviane Reding said citizens needed re-assuring that radio tags would not lead to large-scale surveillance.

My concern here is really not so much large scale surveillance, although to some extent I worry about it. My true concern is from the identity/privacy standpoint, and the possibilty of remote undetected reading of the data on the tag.

Posts of note, who in general have expressed thoughts I agree with/find interesting/thought provoking:

Reading RFID Cards at Yards Away (and previous articles at bottom of entry)
DEFCON RFID World record attempt... (69 feet)

Random Bits, calls, SL, comics

All morning on calls, part of the afternoon as well

Came into the office to start updating my little laptop to snv_50 (from 18).
Spent a lot of time talking to people about work but not getting any noticeable work done.

Now off to meet my family for my mother's birthday.
One of those busy all day, not even sure why types.

Playing in SL last night while doing things about the house. I am trying to build
a jukebox. I have some basic structure and next will be sound before much more
effort in terms of appearence.

xkcd has entertaining comics, and T-shirts. xkcd - Turn Back - By Randall Munroe

For example this, available on a T-shirt, which I own.

Apple study says large monitors improve productivity

All I am saying is that I would be happy with a couple of 24" monitors.

A really good KVM that could switch between them selectively or both at once would be grand as well. A bluetooth capable KVM would also be cool. But I guess it is possible that you could achieve that effect with a dongle.

Macworld UK - Apple study says large monitors improve productivity:

Air passengers 'could be tagged'

Not quite security theater, maybe not at all, but I can't say that the idea of tagging everyone in
an airport with RFID chips appeals to me at all. (Or really that the idea of tagging everyone with RFID chips anywhere appeals to me)

Dr Paul Brennan, an electrical engineer, is leading the tagging project, known as Optag.
He said: "The basic idea is that airports could be fitted with a network of combined panoramic cameras and RFID (radio frequency ID) tag readers, which would monitor the movements of people around the various terminal buildings."

A noted issue that has to be addressed is "ensuring the tags cannot be switched between passengers or removed without notification",
we may have the answer to that problem already in hand. Someone should purchase stock in ear piercing parlors.

Age and Source Verification Necessary For Public Safety, Consumer Confidence

The future of the security is headed toward global identification and source verification of origin of all types of Personnel and usage of electronic identification systems to help with disease tracking and to improve public safety. Our rfid ear tags are International Standards Organization(ISO) compliant and we offer Full Duplex(FDX) and Half Duplex(HDX) transponders as well as high temperature RFID tags. The Company is in the process of becoming an authorized tag reseller to help surveillance organizations integrate electronic identification with the National Security Identification System and Management System. The NSIS will oversee the implementation of a National EID system for many types of animals including Personnel, beef and dairy cattle, swine, sheep, goats, elk, alpacas and llamas.

BBC NEWS | Technology | Air passengers 'could be tagged'
Electronically tagging passengers at airports could help the fight against terrorism, scientists have said.

RFIDtagstcc.com Has no connection to the parody content of this page and does not endorse it in any way.
However if you have need of livestock tagging equipment and such I am sure they would be glad to help you

New Secure Communications over Fiber? Probably not for FTTH

This looks interesting, but only for a point to point connection. Which means that with my fiber to the home, I cannot send new extra sneaky messages to my neighbors. Especially since I am on switched ethernet over fiber and I probably can't afford the hardware.

I took a quick look through the document, and I am sure I missed most of it, but off hand I don't see how you get past any network device or repeater (assuming that the repeater is not repeating noise).

A method for secure communications over a public fiber-optical network

Abstract
We develop a spread-spectrum based approach to secure communications over existing fiber-optical networks. Secure transmission for a dedicated user is achieved by overlaying a covert channel onto a host channel in the existing active fiber link. The covert channel is optically encoded and temporally spread, and has average power below the noise floor in the fiber, making it hidden for a direct detection thus allowing for cryptographic and steganographic security capabilities. The presence for the host channel in the network provides an ad hoc security expansion and increases the difficulty for an eavesdropper to intercept and decode the secure signal.

Sun SecondLife Press Conference...A Disappointing Experience

Disappointed, I forgot to set an alarm so I ended up getting online about 8 minutes after the start.

When I got there I couldn't get into the Sun Pavilion. I was told when I tried to get in directly that the space was invalid.
Stacia and Doug tried to invite(teleport me in), but they got parcel is full messages.
When they finally could invite me I got the following error.

On the plus side, I guess this means it was popular enough to fill up quickly.

I did get told to shove off by a female avatar in mime wearing a shirt but no pants.
(although I am guessing that it was really all rendering problems not really someone in mime, that and the use of words)

So the message is mixed, for Stacia, it worked and was cool, she could hear the conference and I think see the video.
Doug was unable to hear the streaming audio and when directed to the instructions board he was unable to get it to resolve.
(Some items in SL are out of focus, I would guess to save bandwidth, when you look at them the come into focus)

It seems to me that we may need a teleport area for business purposes. After I teleported in, I was standing around for about two minutes with only a shirt on. No hair, no pants. While the thought of virtual streaking the conference amuses me I think it might not be the best idea.

Now while we are waiting for people to join, as opposed to getting on a con call, we need to wait for a couple of minutes after they are in to have pants on before they can come in.

I wonder if you can code objects to reject avatars not in pants (assuming that pants are the generic name for lower body clothing)

Note the mocking...that there in the center, that is where you want to be.
See that tiny little arrow, you are way over there.

Sun Provides Universal Access to Safari Books Online

So Sun has negotiated access for all Employees to the Safari eBook Library.

I have used and been happy with the Safari Books before...unfortunately I find myself slightly disapointed by the following

Unable to generate a temporary class (result=1). error CS2001: Source file 'C:\WINDOWS\TEMP\pvpviplu.0.cs' could not be found error CS2008: No inputs specified

Not that it didn't resolve itself in a moment (presumably after the file was copied into place) but the use of windows in the backend.

Shame on you Safari Books Online, of couse if I worked for Microsoft I would probably be happy.

Maybe we are working out a trade, we get access to your books and we will help you move to our wonderful Solaris operating system.
In any case, Sun Managed Operations would be happy to help you implement the migration AND monitor the entire infrastructure BOTH running on windows and running on Solaris.

Go and Register Yourself for access: Sunlibrary
I must say, that was one of the easiest self provisioning processes I have experienced in a very long time.

It seems that the state of high density WiFi may be
slightly less than carrier grade, at least for temporary third party
installations

The good camera

Not that the Cannon Point and Shoot is bad, just that I
found myself wanting the more easily adjustable manual settings of the
D1x

The Managed Operations CEC blog/multi media Tiger Team
(MOCECBMMTT? OK I made that up)

Interactivity(Web2.0):

It was interesting, and hey I apparently won $200 for the
most
useful sms messages. I have yet to be contacted about my prize, maybe I
should check my VM.

Other winners were for such things as the most
entertaining SMS

Large (Ultra 20 and 24" monitors) prizes for best blog
and such

Not that I am bitter but I would rather have the Ultra
20 than the $200

Much bemoaned by me, connectivity was a major issue

Although apparently it might have been problems with my
laptop
almost as much as anything else, at least when the people sitting next
to me were able to get access while I was not.

Someone suggested brining the backend out to the front.

I think that would have been great, as Dan
indicated...this is a technical conference after all

We should expose the technical aspects

Suggestions:

LISA (USENIX) like content tracks

Refereed papers: A collection of 3 or so papers in a
similar vein for an hour each

Longer Presentation Slots (3 hours or so)

WIPs: Short topics presentation overviews, here is what
we are doing

More accessable BOFs

Tables at lunch was a good idea

real BOF session availability would have been appreciated

Too busy trying to get food and eat too really spend time
finding all the groups

Possibly longer, too much interesting information for the
available time

Maybe it is just me, I would have attended maybe 75% of
the presentations given time

A better scheduler

355 possible sessions (including duplicates)

Presented in a list (depending on search criteria)

Pick by topic/presentation (Content Catalog) would have
been more useful

Then given the list of desired presentations work on
resolving conflicting selections

Allow alternate selections to be maintained, I didn't
attend all of the presentations I selected

A capability to display only otherwise un-selected
presentations for open time slots would also have been very useful

A better view into content

This would prefereably be the content catalog mentioned
above

I ignored presentations because I didn't know what they
were really about

It turns out that I would have liked to attend more and
might have attended differently given better information

Although see above: not enough time...

CEC: Managing Systems at Grid Scale (Our Presentations)

Shawn Ferry (ME) and Brian Smith

In general our attendance was a little bit lower than I had
been hoping for. I think we got in the neighborhood of 80 total...I
think I should be able to find out exactly somewhere.

Both instances went fairly well we had the required Managed Operations
content. In the future we need to go straight to an elevator pitch and
be done with it. I watched as people got bored hearing about how
managed operations does things. Certainly they were interested in the
more technical details CTA, encrypted transport and such. Unfortunately
in our general Managed Operations presentation the less technically
interesting details are more prevalent and this is a geek
conference.

Both presentations had a few Managed Operations staff in attendance for
solidarity. As well as a couple of new Managed Operations staff from
APAC and EMEA.

The first presentation had a slight timing problem, the 15 min max
planned managed operations specific content ran about 30min, in the end
I got
my content in with about a minute to spare and Brian got the last bits
in about 5 after the scheduled end.

The second presentation went more to plan. I was able to go into
more depth on the technical aspects of the monitoring. For those who
attended the presentation. We send an alert.

The only real failure for the whole thing was the attempt for a demo in
the extra 5min before the scheduled end of the second presentation
during the question and answer period. I had maintained what looked
like good network connectivity until I tried to use it, at which point
it all went pear
shaped and I lost network access again.

In brief we covered monitoring methodology:

We have a top down and bottom up approach.

Top Down(A Holistic View):

We start measuring from a user experience, can you reach the web site.

Then a complex web site walking script/library(That I
wrote) performs a:

job submission

waits for completion

downloads and analyzes the results

deletes the job

logs out

At various points in the process if we don't get specific results
(Welcome to the Grid,Job X submitted, Job X Successful, Logout
Complete)
or the process is taking too long we send an alert.

Really in the Middle Here(Business Process Monitoring):

The from a Managed Operations Point of view what we want to know is
what went wrong.

A user can get an login failure for a number of reasons:

External authentication service could not be functional(Sun
Grid does not maintain direct authentication data, you must have a
sunsolve/mysun/store.sun.com account...Go href="http://www.sun.com/identity">Federated Identity
( href="http://www.sun.com/software/media/flash/demo_federation/index.html">Silly
Flash IDM) , see also: href="http://blogs.sun.com/saragates" rel="co-worker">Sara
Gates Sun's VP IDM)

Your name may have been found on the href="http://www.sun.com/sales/its/export/DRPL/index.html">Denied
Restricted Persons List

You may have moved to Brazil (This is a presentation In
joke, I was hoping for some Brazilians to jump up and down and cheer)
or really you are coming from outside the US.

A job can fail for a number of reasons:

Malformed Job

Portal Submission Failure

Grid Engine Failure

Some of these things we can see cause from the middle and some we need
a lower level view.

Bottom Up (A small sampling, we monitor a very wide range):

System level KPIs(Memory, CPU)

processes (sge_qmaster,sge_execd)

services(SMF)

logfiles(errors, failures)

disk utilization

network devices (firewalls, switches, routers)

Examples:

If the qmaster is not running the job will never actually
get scheduled.

If there are no execds running (slots available) the job
will never get executed(or really scheduled because the qmaster won't
schedule it unless it should be able to run.

If queues are in an Error state they cannot run jobs.

If the file system is full it is impossible for a job to
write it's output

Presentation Things I learned:

People want to know why they can't use the grid from
outside the US and
don't quite understand how it is that Sun can have a gird and Sun
employees can't play with it.

We knew this was an issue, we could have just addressed
it straight from the slides

Few Sun employees (who attended our presentation have ever
used the
SunGrid, of course I know that a good number of Sun Employees have used
the Grid it would seem that we just didn't get a lot of them.

A demo would have been well received, but if we were
working with a demo we could have talked for hours

I still need to remember to breathe fully. I find that I
will talk but
forget to inhale full breaths if I am not paying attention.

I just need to pay attention to my breathing. A pause to
take a breath is ok...also it lets people absorb your output

Real learning in a virtual world

The Christian Science Monitor has
an article discussing virtual classrooms in SecondLife.

Some
60 schools and universities have set up shop
inside Second Life - most in the past year. They join a population that
includes real-world business people, politicians, entertainers, and
more than 800,000 other "residents" of the virtual world.

It is an interesting idea, and I am wondering if I am seeing all of
these uses for SecondLife because I have been looking at/thinking about
the Sun Press Conference or if there has suddenly been an explosion of
articles and posts about SecondLife.

Real
learning in a virtual world | csmonitor.com

For the past two years, I had been taking classes to complete my a
Bachelors of Science in Information Technology. I have finished all of
my upper division classes but have about a traditional semester worth
of lower division classes that I never completed the first time through
in traditional schooling.

At the moment I am not taking any classes and the dividing point
between the attendance and not was the continuing classes being located
at a different campus, that and the cost at href="http://www.phoenix.edu/">UOP was
significantly higher than say NOVA,
Classes started at 6 and ran until 10, that wasn't a problem.

The problem was the href="http://maps.google.com/maps?f=d&hl=en&saddr=20098+Ashbrook+Pl,+Ashburn,+VA+20147&daddr=11710+Plaza+America+Dr,+Reston+va&ie=UTF8&z=12&om=1">commute,
the campus at Plaza America (Reston, near Oracle), was a 30-60 minute
drive. The href="http://maps.google.com/maps?f=d&hl=en&saddr=20098+Ashbrook+Pl,+Ashburn,+VA+20147&daddr=9667+Lee+Hwy,+Fairfax,+VA+22031+%28Inova+Fair+Oaks+Hospital:+Thrift+Shop%29+%4038.864221,-77.278170&ie=UTF8&sll=38.983975,-77.42262&sspn=0.487838,1.251068&z=11&om=1">commute
from the office to the Gallows Rd campus (495 and 50 near Fairfax
Hospital) is probably a 90 to 120 minute drive (This is all
in traffic to get there the return commute is probably 20-30 and 45-50
minutes). It goes almost without saying that the NVCC href="http://maps.google.com/maps?daddr=1000+Harry+Flood+Byrd+Hwy,+Sterling,+VA+20164+%28Northern+Virginia+Community+College:+Information+for+Loudoun+Campus%29+%4039.014590,-77.371315&saddr=20098+Ashbrook+Pl,+Ashburn,+VA+20147&f=li&hl=en&dq=nvcc&cid=39085828,-77478526,17427075337703451187&ie=UTF8&z=13&om=1">commute
is better, either to the Loudoun campus or to Reston (nearly identical
to my previous UOP commute).

Having said all of that it would have been interesting to see if a
virtual learning solution based on SecondLife or a similar venue would
have been useful. The commute is certainly shorter, but I have to
wonder if the level of attention that would have been focused on the
learning would have been the same given that it would be easier for
coworkers and such to interrupt by casually walking into the room.

It seems that only time will tell, but a good first taste of an
organized information centric event will be on href="http://blogs.sun.com/yakshaving/entry/secondlife_web2_0_and_collaboration">Tuesday
at the Sun SecondLife Press Conference.

Now I should go and sign up for classes as the next round starts on Oct
18. Should I be ashamed that I am looking at on the ground classes
working for a technical company?

SecondLife, Web2.0 and Collaboration

While we were at CEC the topic of remote collaboration came
up.Specifically the benefit of getting a fair amount of the href="http://www.sun.com/service/mgdopservices/index.xml">Sun
Managed Operations team back together in a team building type
(Bar) environment.

From there discussion of virtual communication and similar topics was
broached. We talked about using AIM,
IRC,
MUD/ href="http://en.wikipedia.org/wiki/MUSH">MUSH/ href="http://en.wikipedia.org/wiki/MOO">MOO and a
couple of related tangents. We then talked about using href="http://secondlife.com/">SecondLife as the
location for collaboration after Jonathan mentioned using it for a
press conference.

The first thing I thought about in this discussion was using a MUSH at
theurgy.digex.net (now defunct) for communication, and some play. I

ASCII although I must admit that I had to search for it and I
thought it was written be someone else).

The paper gives example usages which I will not repeat here, however
the thought was that having effectively a room in which to talk could
be beneficial in our current environment. Many managed
operations employees are flex or are not in the main office in
Ashburn. A couple of times people have attempted to establish
standing AIM chat groups/rooms and IRC channels. None of them has
garnered even small scale adoption.

So the end result here, is that I have created a SecondLife account and
we will try playing around with SecondLife. The next steps to bring
back some of the old theurgy magic would be to create a some objects a
spleen (so you can vent it), some skinheads ( href="http://www.lyricsondemand.com/c/campervanbeethovenlyrics/taketheskinheadsbowlinglyrics.html">to
take bowling), a happy fun ball (to taunt), a tonka truck (to
beep the horn and run into people's ankles) and I may be crossing
servers a game of connect four.

I just don't know that I need the avatar based communication model.
Location/Room/Channel based communication to allow for better
focus and separation of relevant content makes sense to me, it is just
the rest that I don't think I understand/see the need for the rest of
it.SecondLife appears to have a relatively heavy footprint, when I am
navigating around about 50-75% of my CPU and 250+MB memory.
This could be another case of buy a new computer, the one you
are using is 4 years old.

Possibly with a bit less friction and a bit more free processing power
it interaction would be a smoother and I would see more of an enabling
technology and less of a drain on my overloaded resources.

In any case Sun is holding a Press conference about just this topic,
I'll be there.

BBC NEWS | Europe | France to ban smoking in public

BBC
NEWS | Europe | France to ban smoking in public:

Mr de Villepin made the announcement in a television
interview.

"We started on the basis of a simple observation - two figures: 60,000
deaths a year in our country linked directly to tobacco consumption and
5,000 deaths linked to passive smoking.
"That makes more than 13 deaths a day. It is an unacceptable reality in
our country in terms of public health," he said.

My wife will be ecstatic, she is almost rabid in her dislike for
smoking. But then it may be the surgery to remove a lung lobe that her
mother had just after our wedding.

Possibly we will go an visit Paris (Not that the smoking was preventing
it, just that it is a bit more attractive now)
One of the observations I made at Sun's CEC, was that every night when
I got home(my mother hated that, and my wife isn't fond of it*) I had
that ugg, I am going to have to wash the smoke out of my hair unless I
want to sleep with it moment.

Then I realized! no, I won't have to do that at all...no smoking in
public places! WOOT

* The first time I said to my parents that I was going home (back to
school), when I was at home (where I/my parents live), my mother cried.
I tend to call the place I am sleeping home.

hanging with our friends

C- and I are at our friends Jim and Emily's for Jim's Birthday. Talking about our normal array of random topics.

Jim has yet to post, but his wife has indicated that he should not post about her at all.

Jim was at CEC with the managed operations crew...he says he will be posting shortly.

Comment Spam

I am getting annoyed by comment spam.

It had been a problem, then everything was working well again, now it
appears that the spambots are able to recognize our challenge and do
simple math.

I also know that the spam is not personal...but really. Spamming a post
about my wife's brother being shot by a sniper in Iraq, so not cool.

CEC: RBAC Demystified

Brian Bianquart and Darren Moffat

style="font-weight: bold;">Role Based Access Control

What is a Role: An account on the system

Cannot directly login

Could be root (or any user)

What is a Privilege: An attribute of a process

Checked by Kernel

Authorization: given to users directly or through profile

...Cutting back on
following/outlineing until I see
something that I am less sure is readily available online and in docs...

One exec_attr table can be
used across Solaris 8 and 9,
Trusted Solaris (8) and Solaris 10

Here we have a
graphic I have never seen
before...took a picture but it will probably be lame.

I think maybe hand drawings scanned and added to the slides.

href="http://www.flickr.com/photos/shawnferry/261252689/"
title="Photo Sharing"> style="border: 0px solid ; width: 800px; height: 600px;"
src="http://static.flickr.com/113/261252689_892fac0221_o.jpg"
alt="A picture of an RBAC slide">

style="font-weight: bold;">Q:
Can we make it such that user and role profiles can be modified while
the user is logged in or the role is in use.

A: Yes, that
is a bug fixed in update 3...changes may not take effect until next
login, but you will be able to make the change.

Standard RBAC
example:

Execute with elevated
privileges...Start Apache as a regular user on port 80

(As opposed to start as root and drop privs)

I think I was
hoping for more in depth technical details, still time yet we will see

/usr/bin/pfexec is the
closest thing to sudo only without authentication (yet)

pfexec will use the first
profile found....that is the ALL role should be last, otherwise don't
bother to define other profiles.

SMF demo: Allow a user to
change the running state of a service but not the boot state

e.g.

ALLOWED: svcadm enable/disable -t

DISALOWED: svcadm enable/disable (no -t)

DO NOT MODIFY SYSTEM
SUPPLIED PROFILES

File a bug if you think it should be changed

OR

Create your own profiles

Privileges

Kernel no longer only
checks for UID==0

48+ privileges checked instead

Now privilege
sets, next how the privileges flow not really going to note that
down...I know it is well documented I have read it.

Note: Dark Red on
black...hard to see, shouldn't do colors that evaluate to black

Use ppriv -D to debug
privilege access. (Yes this is commonly known)

ACLs

Solaris 10 NFSv4/ZFS ACLs
now match those as implemented in Windows NT/XP=

More info

There is a RBAC and SUDO
comparison slide

Strengths and weaknesses
on both sides the most common requested deltas are being addressed.

Authentication and Netgroups are on/near the top of the list.

CEC: Dtrace Approaches to Real-World Problems

Jim Fiori

Apparently the presentation
is normally a 3+ hour presentation and Jim requested 3 hours, but all
the slots are 60min.

This is a presentation on approach not learning D.

This entry is a horrible hack job on content, too much and I am
learning more than I

can easily condense/digest usefully on the fly.

INTRO

Everyone needs
dtrace...but it is not the first thing to run.

Identify a possible issue use Dtrace to figure out what is going on.

Advice: Practice, Practice, Practice

Approach

use the manual all
examples are in /usr/demo/dtrace

use quantize(), min()/max()/avg() can hide data

Be careful using the PID provider it can impose load on a highly active
process.

Normal system tools still have their
place.

New tools: intrstat (some
others I haven't used)

Privs -- Root level or RBAC...

Zero Probe Effect -- via
instruction replacement

Scenarios

High User Time

hotuser.sh dtrace toolkit

C++ Apps

Watch for small
allocations and short allocations

High System Calls
(>100s)

use aggregation

use pfiles to determine target of File descriptor

System time (>10%
or user:sys near 2:1)

prsatst to
find it, dtrace to examine it

Threaded App.

prstat to find it

plockstat ... to see it, single process

Java

use jstack

Java 1.6 has static dtrace providers

Oracle

Look at I/O and File
systems first

ONLY after regular investigation by DBA (statspack etc)

Sybase

Watch for TCP Nagle
(buffering requests before sending)

Try TCP no delay on client and server

File system

Watch for
periodic pauses check autoup in large memory (>8G) systems

Hints and Tools

Use a sample rate at not quite 1000, to help keep the Dtrace
probe func from running with kernel actions

Dtrace is running in kernel context...you can't just dump
the memory location, you need to dump the user memory space

.mul() and .div() are SPARC V7...the application should be
recompiled

-c flag...use pid$target ... woot

look for system call errors, when things are not working as
expected

see atomic_ops(3c) on mutex_lock/unlock for simple variable
updates

High ctx...look at FX scheduler (good for some apps)

High Migrations...look at binding to a specific processor

libumem for memory leaks

Chime (GUI...uses Sparklines!!!...I like sparklines)
OpenSolaris

Coming

RFE 6311947 svn_43...fun/mod/ufunc/umod

Solaris PowerPC Code Release Announcement

I really like my PowerBook, but it is now ~4 years old and I
continually try to do more things concurrently than I have quite enough
memory and processors for. I also really like Solaris, given a new
MacBook Pro I would use Parallels and Run Solaris as well,
but I would
like to still use the PowerBook for something.

In the near future, within the next 6 months, I will be purchasing a
new laptop. A 15" or 17" MacBook Pro, sooner if Core 2 Duo ( href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2808Mobile%20CPU%20Wars:%20Core%202%20Duo%20vs.%20Core%20Duo">AnandTech:

available.

Running OpenSolaris on my PowerBook will rock.
