Mcrouter is an Open Source tool developed by Facebook for scaling up the memcached deployments:
Mcrouter is a memcached protocol router for scaling memcached (http://memcached.org/) deployments. It’s a core component of cache infrastructure at Facebook and Instagram where mcrouter handles almost 5 billion requests per second at peak.
Here is a good overview of some of the scenarios where Mcrouter is useful. There’s more than one. Here are some of the features to get you started:
- Memcached ASCII protocol
- Connection pooling
- Multiple hashing schemes
- Prefix routing
- Replicated pools
- Production traffic shadowing
- Online reconfiguration
- Flexible routing
- Destination health monitoring/automatic failover
- Cold cache warm up
- Broadcast operations
- Reliable delete stream
- Multi-cluster support
- Rich stats and debug commands
- Quality of service
- Large values
- Multi-level caches
- IPv6 support
- SSL support
For a while now, whenever I post a new blog post to this site, and try to propagate it to my social network accounts, I get an error from Facebook – something about security and content policies this or that:
The automation broke a few month ago, but I never cared enough to do much about it. From then on, I don’t push all the posts to Facebook automatically, but a select few, with manual posting of the links.
Today, even the manual posting broke. I got this:
OK, I thought. Weird, but this happens. Gladly, the error message contains the link to let Facebook know about the problem. And so I do. Just to get to this point:
Now that’s not good. But then again what can I do? I guess it’s a good thing I still own all of my content and have my own place to publish it at.
Hopefully, this will get resolved all by itself soon. Or people will have only kitten pictures to look at…

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.
.. 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!
Facebook Visual Identity – a fascinating story of how Facebook’s visual identity changed over just a few years, and how much effort went into this. It’s always interesting to see what goes on behind the curtains, as the gradual changes of tiny little details are often difficult to spot.
Cyprus News reports that :
The Paphos District Court has issued an injunction against social media giant Facebook, ordering the company to remove a number of offensive comments posted on a local business profile, aimed at a local man.
The comments, posted on February 4, accuse the man of criminal activities. The original post was still on Facebook on Wednesday morning. It has over 1,000 shares.
Charalambos Savvides of the Ch. P. Savvides & Associates LLC law firm, which handled the case, told the Cyprus Mail that Facebook was not only required to remove the comments but also take steps to ensure that future related comments were taken down immediately.
In-Cyprus has a few more details:
The case concerns comments on Facebook made against a bar owner from Paphos who became the target of a hate campaign which attracted thousands of users who shared and liked the page. The man in question was, according to those who had got the ball rolling on popular social media site, committing various crimes around the town and especially against competing bars.
He was also accused of being a police informant that was getting special protection in the town despite his ‘known illegal activities’.
The man has denied all the allegations against him.
It’ll be interesting to see how this plays out.
Facebook is launching a new app – Hello:
Billions of calls are made everyday on mobile phones and people often have very little information about who’s calling them. Today we are starting to test Hello, a new app built by the Messenger team. Hello connects with Facebook so you can see who’s calling, block unwanted calls and search for people and places.
I seem to remember another app with the same name and somewhat related functionality – Hello from Evernote. Apparently, this one was discontinued earlier this year. Surprising, given that some people called it the best business card scanner app.
The functionality of the two apps is not exactly the same but similar enough. Given how little time passed between the “death” of one and “birth” of another, I wonder if this is a coincidence or part of a greater plan.
Mashable reminds us that it’s been a year since Google Reader has been decommissioned. They are also doing a survey to find out if people use more of RSS feeds now or less, what they’ve substituted it with and which tools people are using now to follow their favorite feeds.
I’ve completed the survey, but without any visible results just yet, I thought I’d talk about my situation here. In the last year my use of RSS has decreased significantly. Even though the actual number of the feeds I am subscribed to has increased, I read them less. I share less. I bookmark and blog about less. And it’ nothing but the tool’s fault. Even though Feedly is an excellent tool – fast, flexible, with mobile support, and aesthetically pleasing, it simply is not Google Reader, which I was practically embed into. I’ve looked around for Google Reader alternatives, I tried a few. Feedly is the best of the bunch for my taste, but it’s different.
So, with that in mind, what happened to all that free time that I used to spend in Google Reader? Sadly, I have to admit that I’m much more on Facebook now. Quality-wise, that’s a huge drop. Instead of following my favorite writers, keeping in touch with all kinds of technology advances, and learning new things, I am now participating in flaming comment wars about nothing, and watching videos of cute kittens and bouncing boobs. Cheap entertainment swallowed me and spat me out. It’s exactly like never switching a television set was in the last century. And it’s a pity.
And the saddest part is that I knew it would happen. And if I knew, Google definitely knew that too. And they killed Google Reader anyway. And it’ll be a long time until I let it go…
