Here’s some not so light coffee time reading on IPv6 – IPv6 non-alternatives: DJB’s article, 13 years later – an article that links, among other things to this Ars Technica article, which features some IPv6 statistics. Summary? Sure. IPv6 RFC celebrates 20 year birthday this month with 10% global penetration.
Exponential growth year-on-year is good. But the absolute numbers aren’t so bright yet. Especially considering some of the areas where it wasn’t so successful.
This year’s Jetpack annual report for this blog is ready – have a look. Here’s a teaser:
It’s been a busy year, so I haven’t been blogging as much as I wanted to, but overall, I think I did good (have a look at 2014 and 2013). Just to give you a quick comparison:
I blog mostly for myself, but it’s nice to see a slight grow in traffic. Although the fact that the most popular post in this blog throughout the years – how to check Squid proxy version – is a little concerning, yet funny. Well, at least people still find my “Vim for Perl developers” useful, even though it’s been more than 10 years since I wrote that (and probably five years since I promised to update it soon).
But as I said, I’m quite satisfied with my blogging this year. Hopefully I can continue to do the same in 2016.
Here’s an interesting set of experiments trying to answer the question of how far can you go with HAProxy setup on the smallest of the Amazon EC2 instances – t2.micro (1 virtual CPU, 1 GB of RAM). Here’s the summary.
At 460 req/second response times are mostly a flat ~300 ms, except for two spikes. I attribute this to TCP congestion avoidance as the traffic approaches the limit and packets start to get dropped. After dropped packets are detected the clients reduce their transmission rate, but eventually the transmission rate stabilizes again just under the limit. Only 1739 requests timeout and 134918 succeed.
It seems that the limit of the t2.micro is around 500 req/second even for small responses.
Back in 2013 I linked to some (not so) surprising facts about social media. Two years is a lot of time and a lot of things has changed since. So here comes 100 social media facts and statistics for 2015. These spread from general statistics to service-specific ones, including Facebook, Twitter, LinkedIn, Instagram, Pinterest, Google+, and others. Unlike many other similar collections, this one actually links to sources for every single fact, and provides an easy one-click share to Twitter button. Here are a few to get you started:
- 189 million Facebook users are ‘mobile only’.
- There are 4 billion daily video views on Facebook.
- 50% of unique LinkedIn visitors access it via mobile.
- There is a 50% average increase in comments when a LinkedIn page post contains a question.
- Over 40 billion photos have been shared on Instagram.
- Google+ has 300 million monthly active users around the world.
- Google+ grows at a rate of 33% each year.
- Average time spent on YouTube per mobile session is 40 minutes.
- There are 300 hours of video uploaded to YouTube every minute.
I get my stats anywhere I can find them. Here’s a source that I haven’t seen before – Pornhub Insights, showing all kinds of differences and similarities between Apple iOS and Google Android users.
Waze, the social networking for drivers, presents some analysis of global driver satisfaction. It’s not covering 100% of the globe, but it’s still interesting to look into differences between countries and cities. See if you can find anything surprising…
.. visited Facebook in a single day! I have a hard time wrapping my head around that. I remember the Web before Facebook existed. I remember when Facebook reached a total of billion accounts. And now, we have a billion active daily users. Wow!
Apart from everything else, the amount of engineering that went into creating the platform, growing the features, and keeping it up and running is beyond comprehension.
0 to about 11,000 employees in 11 years. Wow!
In Cyprus runs the story covering some criminal statistics of European Union in general, and Cyprus in particular. There are some analysis to the numbers and some breakdown by type of crime and so on.
If you are visiting Cyprus on holiday, you can be reassured that Cyprus is the safest country in the EU – based on analysis of data from the EU’s statistical office, Eurostat.
From the site, you can find out that there were 2.3 million crimes recorded in Spain in 2012 (the latest data), 4.4 million in the UK and just 8,000 crimes recorded in Cyprus in the same year.
The bit that caught my eye was the term “recorded crimes”. As if decreasing the number of recordings is one of the ways to minimize crime rate…
GitHub blog shares some trends in regards to programming languages, which includes both public and private repositories:
Interesting. I haven’t seen many Java and C# projects myself, but I’m in a very different bubble. PHP stays on #4 for years. VimL, the language in which most plugins for Vim editor are written, makes it to #10 in 2010, which suggests that there are way more plugins than I ever thought. The drop in Perl is also quite notable, but not very surprising.
Search Engine Land reports:
Last year we heard informal statements from several Google employees that mobile search queries would probably overtake desktop queries some time this year. Google just confirmed this has now happened.
The company says that “more Google searches take place on mobile devices than on computers in 10 countries including the US and Japan.” The company declined to elaborate further on what the other countries were, how recently this change happened or what the relative volumes of PC and mobile search queries are now.
Google groups tablets with desktops. So this is just smartphones and does not include tablets.
There’s also an interesting misalignment of this report with some Comscore reports.
