MSIE 6 and HTTP Compression — get the service packs!

A colleague in Germany forwarded me this interesting Microsoft knowledgebase article.


Internet Explorer May Lose the First 2,048 Bytes of Data That Are Sent Back from a Web Server That Uses HTTP Compression


This appears to only happen if another program registers (Real8 Download is the example given in the KB article) to use some of the more obscure Internet Name-Space handlers with Urlmon.dll. These corner cases include rarely used protocols like HTTP, HTTPS, and FTP.

Also, this only applies if you haven't bothered to patch your MSIE 6 for like, oh, two years. So, if you have bizarre behaviour with sites that use compression, use that Microsoft Update thingie you may have heard of.

Possible New Project

I have a lead on a possible new project. Very exciting, and will build on some of the things I have been developing over the last year or so.

But it will mean changing my dream of a Powerbook to one of a functional Linux laptop.

Any recommendations?

GTD: David Allen Roadmap Session Tomorrow

I will be attending the David Allen GTD Roadmap session in Boston tomorrow (September 30, 2005).

Delay: Another Texas Hog Off To Slaughter

Oooohhh! A surprise!

DeLay indicted, steps down as majority leader

I think he should personally be responsible for cleaning up Beaumont, TX.

GrabPERF: Measurement Location Outage

The Gomez measurement location suffered a mental lockup and system hang at approximately 04:00 EDT (08:00 UTC) this morning. Just figured it out, and the system has been restarted.

Sorry for the lack of data over the last few hours.

And, if you want to host a GrabPERF measurement location, drop me a line.

Armed Hamsters! Run!

What more can I add on this?

Vlogging Mini-Conference — Monday, October 3, 2005

For all you local vloggers, there is a vlogging mini-conference coming up in Worcester, MA.

When: Monday, October 3rd, 6 p.m.
Who: You and your interested friends
What: "Meet the Vloggers" Worcester
Why: To learn more about videoblogging and build community
Directions to WPI: http://www.wpi.edu/About/Visitors/directions.html
Campus map to find the Campus Center:
http://www.wpi.edu/About/Visitors/Images/walkingmap.pdf
(The Campus Center is #6, behind Alumni Gym (#3) and next to Olin Hall
(#23). The star is where they are building a new Admissions building and the
circle in the center of campus is a fountain. These are just mentioned as
landmarks.)

Jan McLaughlin, a videoblogger (vlogger) from New York, will be visiting and
we will be presenting about videoblogging. This will include everything from
what equipment to use to how to drive traffic to your site, how to build
community through videoblogging and how to subscribe to news feeds using RSS
so you can watch other peoples' videos. This will be a fun, interactive
presentation. I hope you can make it.


Thanks to Carl Weaver for the info.

Domains for Sale

Ok folks. We sat down and did an evaluation of the finances today...and we're broke.

Very broke.

So, I have had to buckle down and put some of my high-value domains up for sale. Right now, they are up on Sedo.



Yes, webperformance.org is up for sale. Unfortunately, I need the money more than I need the domain right now.

And frankly, these are the only things of value I have to sell right now.

Let your friends know.

23 Miles of Desperation: Life, work, and emptiness on the East Coast

23 miles. Each way.

Every working day, I am supposed to merrily get in my little car and drive 23 miles to work. I know people who drive farther, sacrifice more, with nary a complaint.

Well, now I am complaining. I'm done. It's over. This gig has run it's course.

I won't go into the frustrations I have with my current job. It's not the company's fault. I suppose it is my own for missing the opportunities within the organization. But I guess it's hard to go for the brass ring, if you're not sure this is the ride you want to be on anymore.

I think that I have known that I was done for a long time, but it is very hard to admit it. I am an enemy alien, the only income-earner, 3500 miles from "home". With a mortgage, two kids and a bunch of other things, sometimes you just make do, hoping things will get better.

They aren't getting better.

Now I have to figure out what to do next. Until then, I will have to be the living dead in the office, going through the paces, feeling every second in this place become one more second that has slipped away from me.

What brought this malaise on?

On Friday, I had an interview with Microsoft. They were/are looking for bright people to help them grow their new ad service and analyze the reams of data that will be coming in.

And I bombed the interview.

I know I bombed; there's no way around it.

And you know what: I'm not good enough for Microsoft. And I knew it before the call was over. I could hear the screening interviewer saying to herself: "How do I get this guy off the phone?".

There it was, the chance to move back to the West Coast, to work with people who are trying to do cool things. Maybe not the coolest things, but cool things.

I miss the West Coast. I miss my in-laws. I miss being able to come and go when and where I please. I miss being able to work for the employer I want, when I want. I hate not being able to take on side contract jobs that interest me.

I miss the freedom of being at home.

23 miles gives you a lot of time to assess the future.

Thanks to the sponsors we have so far:


There are a couple of more in the pipeline, and I look forward to working with all of the sponsors.

On this blog and the GrabPERF site, you will see the icon. If you want to support the developer, there are a few items there that will bring a smile to my face! ;)

Introverts Everywhere

Seems that us Introverts are busting out everywhere.

Jonathan Rauch hits for six with this article.

I work at a company run by Extroverts, who, without a second thought, promote the Extroverts and marginalize the Introverts.

The thing is that in my company, outside of sales, the company is dominated by Introverts. In fact, because it is a technology company, the Introverts are really the ones who have the power.

And the Extroverts wonder why the Introverts DESPISE the open plan office -- no cubes, no offices.

Where are the companies run by Introverts, for Introverts?

Weblogs.com: Problem solved

Looks like Weblogs.com resolved their issues.

The Introvert Advantage

Lifehack.org lists the top ten reasons to being an Introvert. As an INTJ, I can relate to these.

10) Work Well With Others, Especially In One-to-One Relationships
9) Maintain Long-Term Friendships
8) Flexible
7) Independent
6) Strong Ability To Concentrate
5) Self-Reflective
4) Responsible
3) Creative, Out-of-the-Box thinking
2) Analytical Skills That Integrate Complexity
1) Studious and Smart


Looks like I need to buy The Introvert Advantage.

Bush bought Florida in 2004

This story should come as no surprise to anyone.

Michael Brown, the embattled head of the Federal Emergency Management Agency, approved payments in excess of $31 million in taxpayer money to thousands of Florida residents who were unaffected by Hurricane Frances and three other hurricanes last year in an effort to help President Bush win a majority of votes in that state during his reelection campaign, according to published reports.

GrabPERF: Making Money on Free

I love Evelyn. And she nails the reason why I have made parts of GrabPERF not free. [here]

Thanks.

Netcraft: EV1 Hunkers down

Lovely Rita she ain't.

EV1Servers Hunkers Down for Hurricane Rita

CEO Robert Marsh says the company has more than 10,000 gallons of diesel fuel on site, and has procured an extra generator in case grid power is unavailable for an extended period. "We anticipate that the coming storm will have no impact on our operations," Marsh said in a message to customers. "However, we are prepared to deal with any eventuality."

GrabPERF: Support comes from the most unexpected places

Later today, I will be discussing an offer of support for the GrabPERF System which came in last night.

I know that I have made my need for hardware and financial support for GrabPERF fairly clear over the last couple of days. However, I was impressed and surprised by this offer of sponsorship/support, especially given who the person making the gesture is.

I won't say reveal any details yet (yes, I am stealing a Buzz Marketing trick from Scoble and Wright), but this is a very exciting development for the GrabPERF System.

Perhaps corporate sponsorship is the model I need to look at for this.

JetBlue: Los Angeles Landing Great Buzz Marketing

Yesterday, a JetBlue plane suffered a failure of the front nose-wheel system shortly after take-off.

After 2 hours and an spectacular light show, the Airbus A320 slowed to a perfect stop on a runway at LAX. [here]

The winners? JetBlue. A perfect landing, flight attendants who were calm in-flight, and the ability to watch the whole thing from your seat on the plane via DirectTV.

Buzz Marketing at its most unique -- what does this experience say about the quality of JetBlue to you?

UPDATE: Shel Israel watched the whole thing. [here]

Slacker Manager Fast Tracks

The Slacker Manager had a great post about Fast Tracking yourself. [here]

When I read the article, I realized two things:


  1. I was coming up on my two-year anniversary with my current employer with no change in responsibilities or roles

  2. I was going to break one of the SM's cardinal rules



Some days it doesn't pay to get out of bed. Now it is time to change the personal marketing campaign.

Important GrabPERF Announcement

Over the next few weeks, you will begin to notice a change in GrabPERF. For those who visit us to examine the summary Search and News Index data, this data will continue to be openly published.

However, by the end of October 2005, all of the detail you have come to expect from GrabPERF will no longer be freely available.

Why am I doing this to a great free service? Am I just greedy?

Two years ago, I started this project as an experiment. Using my six years of Web performance experience, I started measuring sites and analyzing data that wasn't interesting and profitable to my employer. In some short bursts over the last two years, I have sunk at least 3 months of time into developing the graphs, infrastructure, and systems that power GrabPERF

Lately, GrabPERF has attracted the attention of some folks that I truly admire and respect. Folks who value the service and have offered up great suggestions for improving the data that is collected. It is this attention that has lead me to realize that this service is worth something.

There are a number of reasons why I don't just take off on my own.


  1. I am a "guest" of the USA

  2. I would be in conflict with my current employer

  3. Wife. Kids. Mortgage.

  4. My strengths are as an analyst, not as a developer

  5. My strengths are as an analyst, not as a entrepreneur



I am sure there are more, but that should be enough for this point in my life.

What is my goal by moving the meat of the data into a protected area?


  1. Pay to have GrabPERF hosted in a real co-location

  2. Purchase some new hardware for the GrabPERF System

  3. Defray some of the intellectual property costs associated with developing GrabPERF

  4. Defray some of the development cost of a number of very cool features that I have in mind

  5. And the one greedy thing: Daddy needs a Powerbook



As always, if you have a question or comment, drop me a note.

Google: Dear lord. They own everything.

I guess "Own All Data" does not fall under "Do No Evil".

Google Blogsearch: ATOM could be faster

Bob Wyman of PubSub suggested that I should add in the Google Blogsearch ATOM results to see if it any faster than the HTML results.

The answer: they might be. But they aren't.

Why not?

Some bright bulb at Google's Blogsearch team hasn't enabled HTTP Compression on the XML results.

Boys, go back and check your config file and make sure that the text/xml (maybe even text/*) MIME-type is enabled for compression.

Then we will have a race on our hands.

Database Abuse: Fun you can have without the optimizer

You know it's going to be a good day when the DBA comes up to you and says:

"You know those really huge and stupid queries that we always yell at you about? Well, we have some database hardware in place and we thought of you as someone who could stress the system."

Fast hardware. Fast Drives. And a query headed quickly towards the 2-3 million row count and 10 minutes of running time.

I love abusing hardware.

Gap.Com: Finally somebody else notices!

At my real job, we monitor and report on the performance of a number of different e-commerce verticals.

[I will now try and stop using marketing-speak.]

In the retail index, the Gap has been down for nearly 3 weeks. Well, they have come part way up, but it is flaky, and they don't have a search function.

No search function? Oh yeah, let's go shop somewhere else.

Anyway, Erick Schonfeld at Business 2.0 just linked to a story at adfreak about this little re-design outage.

20 days. And counting.

This is unheard of in the Internet economy. Well, not unheard of, but the only other site I know that had a similar re-design outage was Wal-Mart back in 2000.

The Gap is a savvy online retailer. Why couldn't this been done in a more intelligent way? What has made this re-design so problematic?

I upgraded b2evolution yesterday to 0.9.1, which the developers claim had substantial performance improvements.

I believe them.



Kudos to the b2evolution team!

Songs That Won’t Die: Make…It…Stop!

Now it's your turn to suffer with this.

CEMETARY POLKA
Tom Waits


Uncle Vernon, Uncle Vernon
Independent as a hog on ice
He's a big-shot down there at the slaughterhouse
Plays accordion for Mister Weiss

Uncle Biltmore and Uncle William
Made a million during World War II
But they're tightwads and they're cheapskates
And they'll never give a dime to you

Auntie Mame has gone insane
She lives in the doorway of an old hotel
And the radio is playing opera
All she ever says is go to Hell

Uncle Violet flew as pilot
And there ain't no pretty girls in France
Now he runs a tiny little bookie joint
They say he never keeps it in his pants

Uncle Bill will never leave a will
And the tumour is as big as an egg
Has a mistress, she's Puerto Rican
And I heard she has a wooden leg

Uncle Phil can't live without his pills
He has emphysema and he's almost blind
And we must find out where the money is
Get it now before he loses his mind

Uncle Vernon, Uncle Vernon
Independent as a hog on ice
He's a big-shot down there at the slaughterhouse
He plays accordion for Mr. Weiss


Buy Rain Dogs. End my suffering.

Upgraded Blog Code

Ok, the site is now running b2evolution 0.9.1 -- took some swearing and a weird hack to get it to work, but we're back!

If you see any weirdness, let me know.

GrabPERF: Agent Location Disabled

This morning, I asked the ERTW.com measurement location to turn down, as we have completed testing the remote measurement code.

This will have some effect on results going forward, mostly positive. The ERTW.com location had an unusual DNS configuration which was affecting the overall measurement statistics.

I am still recruiting for measurement locations on the West Coast. Drop me an e-mail or leave a comment if you are interested in hosting a measurement location on your linux server.

Fatal Flood: Mississippi River Flood of 1927

I watched part of Fatal Flood last night. It was brutal. And, unfortunately, was echoed far too recently not to be a disturbing insight into the nature of the American mind.

The attitude in this nation towards the disadvantaged and disenfranchised has not changed since 1927. This country is falling away from the city upon a hill, the emblematic vision that fuels the misguided and selfish leadership of the United States.

Katrina exposed the raw, festering wounds in the United States. The stench from the Delta is the rotting of the American Soul.

GrabPERF: Bob Wyman Riffs About Online Consistency

Bob Wyman of PubSub has a great post on the value of online consistency to companies and services. [here]

This is a critical component that is too often overlooked. The need for speed is an addictive goal. But as I have said before, fast is not enough.

Go, Bob, Go!

GrabPERF: Welcome Google Blog Search to the Blog Search Index

You knew it was coming.

Google Blog Search is now in the Blog Search Index.

GrabPERF: Why EXPLAIN is such a useful SQL tool

Now, EXPLAIN seems like such an old school SQL tool. Well, I am here to explain why it's not something you should ignore.

The Index Chart queries were all doing table scans. This can be pretty painful; ok, this can be stupid and EXTREMELY painful. The cause: I was setting sub-optimal date ranges on my queries and making all kinds of crazy date_format calls to format the dates IN THE QUERIES.

Once I changed the code, even when the query cache is cleared, the Index Charts now all run at less than 1 second.

Colour me stupid.

GrabPERF: Whole bunch of bug/performance fixes, part 2

Greg Gershman from BlogDigger found a bug in the Index charts just now. Seems that the chart legend was out of whack with the lines on the chart.

Easy fix. Turns out I was submitting the test ids in a random order. The graph generation component was fine with this, but when I went to build the legend, MySQL ordered the dynamic legend build result in a proper ascending fashion.

Simple fix: when I convert the test ids to an array, I sort the array before proceeding.

Thanks Greg!

GrabPERF: Whole bunch of bug/performance fixes, part 1

Over the last two days I have been trying to optimize the performance of the Index Charts/Graphs. I think I have found the fix, and you should see results for these charts in the sub 1-second range.

To explain how this works, I have to open up the GrabPERF data model and let you folks peer under the hood.

The Daily Index graphs are created using two tables: hourly_site and data. hourly_site is a rollup produced asynchronously at the end of every hour that aggregates the Arithmetic and Geometric means, as well as a count of successful measurements. data contains over 30 days of raw measurement data which is purged at the end of each day.

All of the days in the daily graph, and all of the hours in the hourly graph are pulled from hourly_site. That is with the exception of the most recent day (daily) and the most recent hour (hourly). These are pulled dynamically from data to ensure that all current results appear on the right-hand side of the graph.

With this design, performance was awful. I have tweaked the code as much as I feel comfortable doing (I am an analyst, not a developer!), but it was slow. I increased the size of the query cache, but the boost only lasted for a while. Then I realized that the data I most cared about was being pushed out of the cache by all of the other cached data.

I have now set MySQL to cache queries only on demand. This reduces the load and means that only the results I care about, and which are accessed most frequently, are cached.

When I restart the database, the Daily Blog Search chart takes about 5.5 seconds to generate, and the hourly chart takes about 30 seconds. Yikes!

After this initial pain, both charts take less than one second to be generated.

I am still working on it, so let me know if you see any weirdness.



UPDATE: Seems that the first query of every hour pays the performance penalty, and all other queries will not.

MaxMind: GeoIP Database

Got a quick note from Ed Lin at MaxMind that their free, country-level GEOIP database is updated monthly. You can get the updated files here.

This is in response to some out-of-date info in an old article (here and here) I wrote.

Most of this article is now deprecated, and the GrabIP service is the only remaining element on my site.

Crowsnest Pass: Alberta Weather is Weird

People laugh when I say that I am from a part of the world where, in my lifetime, snow has fallen in every month of the year.

Crowsnest Pass still recovering from freak storm

Power still out for 100 after Crowsnest Pass snowfall

Heavy snow cuts power

I don't make this stuff up.

GrabPERF: Updates to the Index/Multi-Test Graphs

Well, I am starting to try and improve the performance of the slowest graphs on the site, the Index/Multi-Test graphs.

I have managed to completely eliminate the need for the temp tables I had been using, migrating to a pure associative array method. This is in the code that ensures that any tests that return no results for a given time period don't cause PHPlot to throw a hissy fit.

There has to be a way to do it faster. I have a couple of methods I am considering, but arrays within arrays scare me just a little!

Let me know if you see any performance degradations.

Katrina — Zane Comments on the Slave Labour Exemption

Why? Why does this nation do these things? What makes people simply shrug their shoulders and say, "oh well; thankfully it's not me".

Katrina — Stupid, Rich White People Run Your Country

Don't you love this country?

Bush lifts wage rules for Katrina

President Bush issued an executive order Thursday allowing federal contractors rebuilding in the aftermath of Hurricane Katrina to pay below the prevailing wage.


Oh, and in the arrogant, rich, white people category, the award goes to Jefferson Parish near New Orleans. It seems that the righteous folks there have decided to re-water parts of New Orleans so that their area can get up and running faster. [here]

Remind me again why the United States continues to think that they are the moral leaders of the world community.

GrabPERF: Graphing Performance

One of the issues with not being a coder is that development tends to be kludegy. Add in SQL queries and the mess gets worse.

I have made some mods to the Index graphs (daily and hourly) that should only penalize the first person in one of my persistent database connections. After that, the queries are cached.

And while sitting here, I just realized I could improve the speed of this process even more.

I. Am. An. Idiot.

I will fix it....later.

GrabPERF Server updated to PHP 5.1 RC1

I was having issues upgrading the site to PHP 5.1, mainly because it broke a number of the GrabPERF graphs.

Then I read the PHP docs. Turns out that there have been some internal changes to the strtotime() function. I had been using strtotime(date(Ymd H), time()) in the broken graphs; this now returns FALSE, not a numeric value.

A simple switch to strtotime(date(YmdH0000), time()) resolved the problem entirely.

If you see any weirdness, let me know!

Rove and Bush: Staging Photo-Ops, Disposing With Lives

This is enough. Do something.

Read this. Then come back to this forum and tell me how you can support this man.

He and his cronies claim to support the little people. So far, the poor and desperate have suffered the indignity of having their humanity stripped from them by their own government.

Yesterday, we saw a car from Louisiana pass us on the 495. Samantha and I both thought poor buggers. Yet now, I realize that they were driving a very expensive minivan. They weren't suffering. And they were likely staying in hotels.

The United States should be ashamed of their President, their government, and what they have down to their own people.

What will you do to bring humanity back to the United States.

Dear Karl Rove: Shut Up, and Go To Kansas

<RANT>

George Bush is lame, and a lame duck.

He is a stooge, only in place to ensure that the right-wing packs the Supreme Court for a generation (Think Pelican Brief).

Now, after playing politics with 9/11, Karl Rove is playing politics with Katrina.

WHY?

What does playing politics mean? How many lives does it save?

FEMA failed. DHS failed. Santorum wants to gut NOAA so it can fail during the next crisis.

Karl Rove committed treason. George Bush committed stupidity. Brown and Chertoff were shown to be useless in the face of a disaster.

SHUT UP
.

Unless you are going to New Orleans to DO something, stay home. Stay off the TV. Stay out of the media.

The White House has NOTHING to add to the conversation. It has added nothing to the effort to save these people.

The president of the oil companies and conservative religious fanatics failed the United States. And Karl Rove is trying to make the chimp look good.

Karl, you have failed. You are the most reviled man in America. I think that Karl Rove should be made to clean the Superdome. By hand. Alone.

Tags: Bye-Bye, and write when you find work

I am basically a lazy sod.

However, I have been dutifully tagging my posts, but being less and less enamoured of the process. For me, it is a manual process, involving visits to Technorati and copy and paste.

People would say, well, just write a widget to do it for you.

No.

It's over. And Darren Barefoot finally pushed me over the edge. [here]

The search tools have to get smarter. It's not 2004 anymore. The obsolesence cycle is getting shorter. The search tools should be able to classify the data without a nudge in the right direction.

Just goes to show that two malcontents from Canada who survived Tourism Victoria can start something.

The last thing I needed…

Looks like today is the day I either swap out my laptop for a new one or re-build this one from scratch (or a disk image). MSIE does not retrieve pages anymore, and I have been using this machine for nearly 9 months and the registry is likely a complete mess.

Mmmmm...love that shiny, new install smell.
