It's a more quite time now. Redis 2.6 released, the sexism issue almost forgotten. Time to relax, be wise, and focus on work. Right, but, that's not me. I've a few more things to say about what happened, and to reply to the many people that asked me why I felt "obligated" to stop using my Twitter account as before, with a mix of work, thoughts on technology, and personal stuff.

I can change idea easily if it is the case, but this time it was not the case. As much as people that criticised me for my blog post may think that I've a problem, I also think they have huge limits. Oh well, different opinions, I don't like you, you don't like me, I don't freaking care after all. I don't think on the same line as most people alive if that's the matter.

h2s writes about Linus:

"I love this guy's balanced approach to steering the kernel. Somebody asked whether a bunch of security-related patches would be getting into Linus' tree, and his response was great.
Basically, he spent a few minutes explaining how security people tend to think that problems are either security problems or not worth thinking about. They see things in black and white and only care about increasing security at any cost. He said performance fanatics can be the same in their approach to improving performance, and he tries not to treat security or performance patches as being too massively different from any other types of patches such as ones for correctness.

I don't like people that are using recent EC2 problems to get an easy advantage / marketing. Stuff go down and cloud services are not magical, it is better to adjust the expectations.

But there are other reasons why people IMHO should consider going bare metal.

* EC2 (and similar services) are extremely costly. With 100 euros per month you can rent a beast of a dedicated server with 64 GB of RAM and fast RAID disks.

* As you can see you are not down-time safe, and to be down together with a zillion of other sites may be a good excuse with your boss maybe, but does not change your uptime percentage, so it's a poor shield.

Redis 2.6 is finally out and I think that now that we reached this point we'll start to see how the advantages of a release that was already exploited in production by few, will turn into a big advantage for the rest of the community.

Scripting, bitops, and all the big features are good additions but my feeling is that Redis 2.6 is especially significative as a step forward in the maturity of the Redis implementation. This does not mean that's bug free, it's new code and we'll likely discover bugs especially in the early days as with every new release that starts to be adopted more and more.

And there is Pieter Noordhuis on stage right now!

You are there in the morning with your coffee in front of you, scanning pull requests and bug reports, then you see a conversation around a commit among a few guys that modified the code to make it better, than there is another one suggesting to improve it in another way. You click in the account names and you see this people with their transparent eyes and your trust in humanity is restored.

Takeaways:

1) Making videos is in some way harder than doing a talk live.
2) Screen Flow is awesome, but could be improved with more video editing capabilities, apparently you can't "cut" the video.
3) The problem is to upload files when they are big and you have normal ADSL connection :-)

But it feels good to be able to send the video talks a few days in advance, so the conf organizers will be able to perform editing, filter audio if needed, whatever.

of the final recording of the videos I'll send to the Redis Conf. That was hard! The timing of the conf was not excellent for my attending, but producing the video was also less trivial than I thought, but finally I've the slides, an idea about what to say, and the ScreenFlow skills ;) Maybe after this experience I'll produce some video tutorial of Redis new features as I introduce it, in order to accelerate the adoption of new things in our community.

Now back to work...

Good article by Josiah Carlson on Redis memory usage estimation, including copy-on-write worst case during BGSAVE:
