Google Maps glimpse into the past

Google update their Maps service on a semi-regular basis but their images of Cork City are hopelessly out of date.

Elysian Building Site
The Elysian Building Site

The Elysian will be a large 17 storey tower with offices, apartments, shopping centre, parking and gardens. It’s been years since that building site looked like it does in the image above!
Key:

  1. Elysian building site.
  2. Cork City Hall. (The building work behind that is now complete)
  3. Cork City Fire Brigade HQ
  4. Anglesea Street Garda Station
Patrick Street
Patrick Street, Cork City Centre

They can be forgiven for not having this updated. The large block marked with red has only recently been demolished while superwomen walk past and railing hide the view down by the bottom-right corner of the block.

Nice to have these before pics of the city.

Code running on a web server is more like a service. The code stays on the server and therefore code does not have to be made public. GNU Affero GPL rectifies that problem. However, if WordPress was licensed under such a license anyone who uses it would have to release any modifications they make. Read the post for more details about why the loophole still exists in GPL 3.

I really have to resurrect that link posting plugin I wrote for WordPress. Meanwhile, if you’re groaning under the deluge of comment spam that Akismet catches, try this modified version which orders the spam comments by IP and url. Rename the file to akismet.php and drop into your plugins/akismet/ folder. It’s the same idea as the Akismet Worst Offenders I blogged last year but rewritten from scratch. Looks dog ugly but maybe someone will carry the work forward?
Later today I’m going to check in changes to the super cache plugin to create html files in the root folder of your blog. You have to explicitly name the path, so there’s no danger that your blog directory will be overrun with lots of new folders.

Donncha's Thursday Links

I have to admit, I preferred how WP 2.2 displayed lots of draft posts on the edit and post pages. Having to go to the Write page and click on the “54 more” link is annoying. For some reason, this post didn’t show up as the newest draft. Now it does, maybe because I deleted another (newer) draft post of the same name. When I created another “Donncha’s Thursday Links” post it didn’t show in the drafts list either. I had to search the drafts posts for “donncha” and it appeared at the bottom of that list. Strange.

I should get used to having my photos ripped off, but I don’t think I ever will. It’s as upsetting now as it ever was.

PS. Ray D’Arcy appears on the Restaurant tonight on RTE 1 at 8.30pm!

  • A few days ago I blogged without comment a video by Larry Lessig on the Creative Commons. It’s a great video, but I won’t use it to license my photography. Why? Jim covers most of my reservations about the scheme. This might come as a surprise to some but one of the main reasons I “reserve all rights” on my Flickr stream and photoblog is because I would like some say in how my images are used. I would be horrified if a picture of my son was used in a derogatory way, or if a photo of a stranger on the street appeared in an inappropriate context.
    If I was going to use one of their licenses then it would have to be the cc-GPL. I’ve released GPL licensed software for the past 10 years and at least then all materials used in any derivative works would have to be made available. Would that mean a magazine featuring a GPL licensed image would have to make PDF files of their magazine available? I hope so. I also do not want to give up my right to redistribute my image under a different license. As the original copyright holder of the work that is important to me. Anyway, my duck photo shows that many people think photos found online are there to be ripped off and used. I don’t think it matters what license you use.

Why I think StumbleUpon is better than Digg

Compare the following two graphs taken from Google Analytics.

stumbleUpon traffic
Hits from StumbleUpon
digg traffic spike
Hits from Digg

At first glance, an appearance on Digg.com looks great! All those lovely hits. 5 times more in a few hours than StumbleUpon sent over a few days. What you don’t see there is the bounce rate. That is the rate at which people visit your site and never come back.
According to Google Analytics, the StumbleUpon bounce rate is 29.94% while a whopping 77.58% of Digg users visit once and leave. I’d rather have the visitor who comes to my site, browses around and then hopefully subscribes.

It’s also easier to gain attention on StumbleUpon and it is likely to continue to send traffic to your site long after your Digg submission disappears into the nether regions of that site never to see the light of day again. That bump on the StumbleUpon graph a few days later was yesterday as people came back into work after the weekend.

In this example, there’s a large difference between the number of visitors Digg and StumbleUpon sent, but StumbleUpon can send you a torrent of traffic too. After I stumbled Grandad’s How to survive your first Guinness post, his site received an extra 16,000 hits plus his subscriber count jumped by a few as people enjoyed what they read.

So, sign up on StumbleUpon and add me as a friend and I’ll pop by for a visit.

Update! Grandad sent me a graph of his traffic over the last month. That big spike is the “StumbleUpon Effect”, but the extra traffic afterwards is more interesting. That’s from his new-found regular readers. Glad I could help!

Rescued from a terrible fall

If you live in Australia you may remember a news story about a young man who slipped and fell from a waterfall at Mount Glorious, west of Brisbane several weeks ago. The injured man was very badly hurt but his friend stayed with him and cared for him until help arrived. From the news report:

Inspector Hunter Nicol says he was lying face down in the water and a hiking companion jumped in and dragged him out.

“He has got severe head injuries, some leg injuries from what we can gather initially,” he said.

“He’d fallen approximately 10 metres, landing face first into water and it was only for his friend – he was able to get him out and look after him until help was able to arrive.”

Why am I blogging about a hiking incident that happened on the other side of the planet? Because Bartek, the friend who saved the injured man’s life, is my sister-in-law Suzanne’s boyfriend. Here is his story. He sent me photos but they didn’t attach properly unfortunately. Suzanne sent on the images you see here later.

Mount Glorious creek bed My friend’s name is Andrew Davison but I call him Davo at times from our school days. Suzanne tells me you would like a more comprehensive account of what happened 2 Sundays ago, so here goes.

08-falls.jpg I hadn’t seen Andrew since we climbed some of the Glass House Mountains, Queensland about 5 months ago. On this trip, he was eager to show me the Mount Glorious creek bed from Greens Falls to Love Falls (pictured). There was enough water at Love Falls for a little cool down dunk in the water before we headed up Love Creek and we got up to a pretty huge waterfall which we climbed to the top to have a better look before heading back.
Andrew climbing It was about 1:30pm and we were about an hour’s walk from the car when we where retuning through a fairly difficult portion of the creek. We had to go around a dried up water fall as it would be unsafe to try going straight up. Andrew was about 10m from the bottom of the creek bed and had reached a bit he was struggling with. I told him to grab hold of the bag strap I lowered down and to give the rock in front of him a big tug to see if it held, and then use that rock for leverage. This he did but without holding onto the bag to check the rock properly. Our worst fears were confirmed when a 6-8kg rock came straight out of the side of the ravine and Andrew fell from his hazardous perch. The rock followed him down and I believe smashed his right eye during the fall. He landed back first into about 20cm of water, knocked him unconscious, and started to sink into the water as the pool turned crimson. I flew down the side of the ravine with little thought to my safety and made it to him in about 35 seconds, apologies to the vegetation on the way!

I slid straight into the waist deep water near Andrew and put both my arms underneath his, with my left hand on his forehead to stabilize his neck, my right arm around his chest I heaved… Damn he was heavy! My underwater foothold slipped and we fell back into the water and again I heaved him up the side of the rock. As he lay there he coughed up all the water he had swallowed and started coughing and moaning. Once I got him in a stable position I checked him out. There were major lacerations to his head, possible skull fractures, a hole in his right cheek about an inch long, his right eye was mush with multiple fractures bulging out, two major lacerations on his right knee and one on his left knee. So much blood.

Having only my shirt available, I strapped his right knee to stop that bleeding and put a thick woolly sock on the head wound so he couldn’t feel all that blood flowing over him and cause him to panic even more. I pulled my mobile phone out of the bag while cradling Andrew so he would stay still and be more comfortable and called the emergency services. it took them about 5 minutes to put me in contact with emergency personnel who told me to do what I had already done; check his pulse, his breathing, see if his eyes were reacting to light and movement, ask him questions, keep him conscious and not to give him any water. He was in a really bad shape.

We had a very long wait of two hours keeping leeches, flies, mosquitoes, ticks and ants off us, keeping Andrew moaning and concious and trying to keep him warm with my blood covered body while answering phone calls to stupid ass people that couldn’t follow my directions.
“Just ask the F***ING locals!” I felt like screaming down the phone but said so politely. Finally two locals did find us and a girl of about 16 came climbing down to us like a natural. She talked to Andrew while her brother screamed to the 2 paramedics, the fireman and the police officer who had fallen well behind, “Hurry the f*** up you slow bastards. He’s down HERE!”

helicopter Thank God help was here. I told the girl to use her white shirt to wave at the helicopter at the clearing and her brother to take off his shirt so we could keep Andrew warm as he was already shivering uncontrollably. Within 20 minutes the chopper dropped off 2 more paramedics who helped to stabilize Andrew. Then it came back after another 20 minutes to drop off the stretcher and returned after 45 minutes once we had Andrew in it and had carried him down to the clearing about 20 meters away and about 15 meters below where he fell.

Anyway, Andrew was sent home today from hospital. He will have to return for at least 2 more operations to remove bone fragments from behind his eye again and for his right knee. Apart from that he is healing quickly and looks like he will be back to normal in the near future.

Thanks Bartek for sharing the story of the rescue. I think you were a hero that day and Andrew is lucky you kept your head and knew what to do. Hopefully you’ll never have to use those skills again!

100,000 page views in 5 minutes

Now, that’s why you can’t believe benchmarks. Sure, this server was able to serve 100,000 page views in 282 seconds but:

  • Requests were made from a VPS in the same datacenter. No need to worry about slow clients, or maintaining network connections to many remote clients.
  • I used Litespeed Web Server instead of Apache.
  • Was it realistic? Even a digg that sends you say, 8,000 page views in an hour, isn’t going to exercise your server that much unless your page is chock full of graphics, css and Javascript. (oh wait, web 2.0 ..)

So, Litespeed’s webserver is the one to go for? Maybe not. I can’t for the life of me get compression of the static cache working. When I do, the browser tries to display the gzipped data directly. I can enable the webserver’s gzip function but from tests I don’t think it caches the resulting gzipped file. (btw – mod_deflate, the Apache2 module that does the same thing suffers from this problem too!) Later – testing this again. Litespeed allows you to set a a gzip cache directory. For normal traffic it’s worth doing so pages load faster.
The mod_gzip site is a great resource if you want to find out more about compressing HTTP content.

How did Apache cope? I was serving 100 concurrent requests and Apache didn’t cope too well. It did serve all the file requests eventually but the load average jumped to just over 50 and the site was unavailable to anyone else. It’ll serve 1000 requests for a static file fine, even 10,000 too, but under constant load the server starts to wilt. Unless you have the RAM to keep enough Apache child processes going all the time you’re going to start swapping.
Meanwhile, Litespeed hardly caused a blip in the server’s load average. I’m quite impressed and I’m running it now. It’s also what powers WordPress.com. Even if you’re not using WordPress, you should look at alternatives to Apache.

This leads me nicely on to announce WP Super Cache 0.4! Download it here!

Major new features include:

  • A “lock down” button. I like to think of this as my “Digg Proof” button. This basically prepares your site for a heavy digging or slashdotting. It locks down the static cache files and doesn’t delete them when a new comment is made.
  • Automatic updating of your .htaccess file. (Backup your .htaccess before installing the plugin!)
  • Don’t super cache any request with GET parameters. You really need to use fancy permalinks now.
  • WordPress search works again.
  • Better version checking of wp-cache-config.php and advanced-cache.php in case you’re using an old one.
  • Better support for Microsoft Windows.
  • Properly serve cached static files on Red Hat/Cent OS systems or others that have an entry for gzip in /etc/mime.types.
  • The Reject URI function works again and now uses regular expressions!

Support queries should go to the forum. Make sure your posts are tagged “wp-super-cache”, but if you post from that link they will.
