My new iPhone weather app

Thursday, April 10th, 2014

I know I haven’t posted anything for a long time (sorry about that), but it’s mostly because I’ve been working on my new iPhone weather app Today Is Like, which has just been released today. 15 months in the making, it focuses on comparing today’s temperatures to historical averages from around the world, and in doing so, hopefully adds some interesting context that’s not available in more traditional weather forecasts.

If that sounds interesting, visit the app’s website at http://todayislike.com where’s there’s lots more detail, including a demo video of the app in action.

Server move

Sunday, January 13th, 2013

Just a quick blog post to explain that Carsurvey.org and other CSDO Media sites have moved to a new server this morning. Hopefully the move will go unnoticed by most people, but the underlying Linux distribution has changed (from RedHat Enterprise 5 to Ubuntu 12.04 LTS), so if anyone spots any issues that my testing has missed, please let me know.

Bulk content removal from Carsurvey.org

Saturday, June 16th, 2012

I’ve just released a very big change to Carsurvey.org.

I’ve spent almost a year and a half trying to escape the effects of Google’s Panda algorithm, with no luck so far.

Having cleaned up the design and ads as much as possible, the only thing left is to try to remove content from the site that may be triggering the Panda algorithm, due to a perceived low quality level. I’ve been doing this manually over the last year, but with so much content on the site, it’s taking too long.

My new solution is to analyse every piece of content on the site with an automated script, which looks for signals that may be indicative of poor quality. Things like unusual sentence lengths, strange punctuation or capitalisation. Content that exhibits enough of these signals has now been removed from the site, pending manual review. In total, about 15,000 reviews and 38,000 comments have been removed. Reviewing and restoring all of that content is likely to take several years.

Sadly, there will be a lot of false positives as a result of this process; perfectly good reviews and comments that just happened to have some characteristics that my script was looking for. If anyone is concerned about the fate of a particular review or comment, please email me (steven@carsurvey.org), and I’ll prioritise it for restoration to the site.

A new look for Carsurvey.org

Friday, November 4th, 2011

I’ve just made a massive change to Carsurvey.org. There’s a new theme, that’s HTML5 compliant, with completely fresh CSS (rewritten from scratch, with the help of SASS and Normalize.css). The site has a new logo, and for the first time, has a favicon.

The new theme is designed to be less busy and more consistent, with the content taking priority over ads (there are less ads, and they’re in less prominent positions). The theme is also built around the 980px viewport width assumed by the iPad, so it should work especially well on that device.

There are still some tweaks to be done, but I’m crossing my fingers that visitors will be as enthusiastic about the new theme as I am.

New review layout for Carsurvey.org

Tuesday, August 2nd, 2011

I’ve just debuted a new layout for Carsurvey.org, where instead of each review having its own page, there are multiple reviews per page. This change has been driven by several factors:

In February, Google released an algorithm change known as Panda, which reduces the rank in Google search results of sites that the algorithm judges to be low quality. It’s not exactly clear how Google measures this, but this post from Google is the most detailed description they’ve given:

http://googlewebmastercentral.blogspot.com/2011/05/more-guidance-on-building-high-quality.html.

Carsurvey.org seems to have been penalised by the Panda algorithm, and whilst I believe the site is high quality and useful to visitors, there’s always room for improvement.

Duplicate content due to the site’s layout and quoting in comment replies could have been an issue, and changes have been made to reduce this; mostly by searching for duplicate comments using a longest common substring approach, and replacing large quotes with links that indicate which comment is being replied to.

The site also had lots of pages that only contained a short review or comment, and those weren’t exactly the best experience for visitors. The new layout uses some smart pagination algorithms to make sure that pages that are thin on content will be very rare, and in the exceptional cases where they are unavoidable, they’re marked as NOINDEX so search engines know to ignore them.

Where there are only a few short comments, they’ll be added to the end of review, rather than existing on their own page.

Ads have been reduced in size and number on the site, in case that was causing problems.

Also, the ability to filter comments by whether they are on-topic or not has been removed. It wasn’t being used very much, and didn’t justify the complexity it added to both the user interface, and the underlying code base.

As usual, any feedback would be welcome. This is still a work in progress, and whilst I’m not planning any major changes, there will be refinements coming over the new few months, based on how well the new layout performs with visitors.

Carsurvey.org Disk Issue

Thursday, February 17th, 2011

It’s that time of year again. Carsurvey.org’s web server has suffered a disk failure. Thankfully all the data seems to be safe. Have disabled new reviews and comments until I’m happy things are back to normal. Expect some downtime soon when the server is turned off to replace the faulty disk.

Changes to emoticons on Carsurvey.org

Monday, February 15th, 2010

For years, the emoticons (happy, sad and neutral faces) shown on the lists of reviews on Carsurvey.org have been based purely on the answer to the question “Would you buy another car from this manufacturer?”

Although this question was often a good indication of a reviewer’s overall opinion, there were a significant number of reviews where it didn’t work at all.

In order to address this, the numerical ratings (Performance, Reliability etc) are now also taken into account when deciding which emoticon to display for each review, and this seems to significantly reduce the cases where the emoticons don’t reasonably reflect the general sense of the review.

Carsurvey.org is back to normal

Wednesday, December 23rd, 2009

Replacing the faulty disk didn’t quite go to plan, and the RAID array needed a bit of help to be coaxed back into life (think defibrillator), but things have been up for a while now, and the patient seems to be recovering well. Will be keeping things under close observation, but I’m confident enough to reopen the site to new reviews and comments. Hopefully this is the last disk related issue for the foreseeable future, as I think Carsurvey.org has had more than its fair share recently.

Disk issue with the Carsurvey.org server

Wednesday, December 23rd, 2009

It seems to be the year for disk failures.

The good news is that the RAID array has done its job, no data loss so far, I’ve got completely up to date backups (which I know restore properly), and engineers are looking at the physical server right now.

As a precaution, new reviews, new comments, and the members area have been disabled till the problem has been fully resolved. Don’t want to risk losing anyone’s new contributions if things go horribly wrong. It’s also probable that the server will be offline for a period while hardware is replaced. Fingers crossed the faulty kit will be replaced soon, and we’ll be back to business as usual.

Policy changes on Carsurvey.org

Thursday, December 10th, 2009

Things have gotten out of hand with a small number of people who are spending significant parts of their waking time beating each other over the head with basically the same arguments, day in day out.

Things are getting more personal, and the volume of comments is increasing. Enormous amounts of my time are being spent trying to keep things vaguely civil, to the detriment of the rest of the site, and frankly my own quality of life.

The people involved need to accept that they’re never going to convince the people who hold the exact opposite views.

Starting from today, the following policy changes are being made:

There is going to be a very low threshold of toleration for comments that essentially repeat points made elsewhere on the site, especially if those comments are not about your experience with a particular model, but are essentially part of a wider discussion about politics or economics.

Less toleration for unpleasant comments. I’m not going to spend time editing comments that contain unnecessary jibes. Those comments will simply not be posted to the site. People can learn to tone their comments down, rather than having me edit their comments to make them acceptable. New visitors will get a little leeway on this, as they’re less likely to understand where the boundaries lie.

As a general guide, here are some things that examples of things that I consider acceptable/unacceptable:


Acceptable: Posting a single comment about the recent recall of a vehicle by a manufacturer, which hasn’t been mentioned elsewhere on the site

Acceptable: Posting new information about an old recall

Unacceptable: Posting multiple comments about recalls already mentioned elsewhere on the site, which simply repeat information available elsewhere


Acceptable: Posting a single comment about your personal experience with a model to a relevant review, and then following it up with relevant replies. This can include your experience with competing models

Acceptable: Posting multiple comments that address queries raised by other comments about a particular model

Unacceptable: Posting your unsolicited views of a particular model across many reviews


Acceptable: Stating that someone’s views on a car are mistaken, with explanations of why this is the case

Unacceptable: Any comments that directly or implicitly are negative about other contributors to the site. It’s fine to say that someone’s wrong, but not to suggest they are an idiot or a traitor.


Or to put it another way:

I don’t expect to see essentially the same comments being repeated either across different reviews, or within the comments of a single review. We live in an age of search engines, and Carsurvey.org designed to be easily searchable. No need to repeat arguments ad infinitum.

I expect everyone who participates on Carsurvey.org to have a sense of respect for the other people who’ve taken the time to add their contributions to the site.

My hope is that these changes will improve the signal to noise ratio of Carsurvey.org, as well as the general atmosphere, without restricting the subjects that can be discussed.

As usual, complaints or feedback should be addressed to steven@carsurvey.org, or added to the blog comments on this site. Please don’t add comments about this to Carsurvey.org itself.
