20 years a CTO, engineer, and humanist — in no particular order.

You'll find me on most online services as teoruiz.

teoruiz··on Namecheap now officially accepts Bitcoin
It's a great step towards domain anonymity, but at the end of the day Namecheap is a company in the USA that needs to comply with USA law and its enforcers. And we know it's not the most privacy-friendly country in the world.

To be fair, registering a .com domain is a bad idea if you want to stay anonymous. Go for a .is, a .ch or even a .eu.

teoruiz··on Posterous to Tumblr
It would be great if you could select in which Tumblr blog you want your Posterous' imported to.
teoruiz··on Kim Dotcom's New Mega Encrypted Cloud Storage
I still have my doubts about their privacy practices, I would love to see a detailed technical article on how the actual PKI infrastructure works.

I could register and (apparently) generate a private RSA key, which was sent to mega.co.nz as part of a HTTP POST payload. I wonder if that's only used for the current session, which I guess is mandatory, but I'd like to understand more: how does the model work for sharing, for instance.

teoruiz··on KISSmetrics down for 8+ hours
I'd love to see a postmortem.
teoruiz··on GNU Emacs 24.1 released
I'm getting a connection refused for http://emacsformacosx.com/
teoruiz··on Google Maps: The Never Ending Quest For Perfection
Offtopic: I really don't get the point of the blogspot.com domain now redirecting to blogspot.com.TLD for every Blogger blog.

I actually find it a little bit annoying.

teoruiz··on The Facebook Offering: How It Compares
It's just crazy how slow Firefox gets at the simplest samples from the D3 site.

Just try the "Evolution of Wealth & Health of Nations" in Chrome AND Firefox http://bost.ocks.org/mike/nations/

Is there any open source version of your port?

teoruiz··on Pinterest Architecture Update - 18M Visitors, 10x Growth, 12 Employees, 410 TB
That's actually right, S3 costing at $39k/month seems completely crazy.

No wonder 37signals decided to switch to their self-hosted storage solution[1].

teoruiz··on Pinterest Architecture Update - 18M Visitors, 10x Growth, 12 Employees, 410 TB
According to the article Pinterest is spending on AWS EC2 >$30k to support 18M visitors/month.

Data: $52/h (peak time, let's say 18 out of 24 hours) and $15/h (night time, let's say 6/24).

Edit: as pointed in the comments $30k/month would only be the EC2 costs.

teoruiz··on Behind the Scenes: The NYT Facebook IPO Graphic
What's the software used to actually generate the interactive charts? I found it somehow amazing they're not Flash.

I can see a reference in the HTML source code to something called "Stencil".

teoruiz··on NASDAQ:FB
I think I missed a couple of smileys in my comment, I just wanted to share my posting process because I liked the split test bit :)
teoruiz··on NASDAQ:FB
I just went to finance.google.com myself and then thought it would be interesting to HN users and posted it right away. And to be honest I didn't check the "new" queue for already submitted links.

Regarding the accidental split test I think the "NASDAQ:FB" title is somehow more appealing.

teoruiz··on NASDAQ:FB
Apparently it starts trading at 11:00 EST.
teoruiz··on Amazon CloudFront - Support For Dynamic Content
Supporting the query string as part of the cache key is big news for CF users.

Thanks a lot.

teoruiz··on Samsung Galaxy S III hands on: fast, thin, and a little bit cheap feeling
Are you actually happy with the HTC One X?
teoruiz··on WWDC 2012 (June 11 - 15)
Any guesses about an iPhone 5 being released there?
teoruiz··on The SSL cert for MI5 (the UK Secret Service) has expired
The site seems to be using a renewed one now.
teoruiz··on Facebook acquires Instagram
It doesn't say but any wild guess on how much did Facebook pay?
teoruiz··on A Tcpdump Tutorial and Primer
This is gold. Straight to my pinboard.
teoruiz··on New Medium Instance, 64-bit bit Ubiquity, SSH Client
Not really, no. I had to push for the bandwidth prices, but not for the hardware. These are the detailed specs of one of those €448/month servers (Sep'11 prices) :

- DELL PowerEdge R710

- 2 x Six Core Intel Xeon E5645 2.4GHz, 12M cache

- 4 x 300GB SAS 15K RPM Drive (RAID10 controller with 256MB cache)

- 48GB DELL RAM

I would say their reliability is great on the dedicated side (their Cloud reliability is just OK) and their "fanatical" support is really good, as they advertise.

Edit: just to clarify these are Rackspace UK (LON3) prices.

teoruiz··on New Medium Instance, 64-bit bit Ubiquity, SSH Client
We have most of our workload running on Rackspace Cloud Servers (UK) and the more improvements AWS make, the more overpriced and ridiculously underperforming the Rackspace offer becomes:

Underperforming: I don't get why the bigger Rackspace Cloud Servers don't get more CPU cores, just a bigger share of the original 4 cores on the host server. This might look fine but at the end I just want more processes (PHP threads) running at the same time.

Overpriced: The pricing is really high for Cloud Servers. I'm paying around £460 a month for a 16GB RAM Cloud Server (4 cores, 620GB (!) disk). For around €448 I have a Rackspace dedicated server with 48GB RAM, 2 x 6 (modern) cores and a 480GB RAID10 array.

I'm actually switching most of our workload to dedicated hardware, it's less cool but it's just cheaper and faster, in this case.

NB: We tried AWS but the MySQL IO performance, either in EC2+EBS or RDS, was not enough for us.

teoruiz··on PHP 5.3.10 release delivers a critical security fix
Anybody knows if it affects PHP 5.2.x?
teoruiz··on New AWS Region in Sao Paulo, Brazil
Just a note: São Paulo in Brazil is named after Paul the Apostle, so in Spanish it would be San Pablo.
teoruiz··on Facebook for iPad
It is indeed kind of lame.

If I did that at my company I would get quite a reprimand from the CEO :)

teoruiz··on Stephen Colbert's tribute to Steve Jobs
Last 10 seconds are probably the best tribute I've seen yet.
teoruiz··on Realtime Analytics Using MongoDB, Python, Gevent, and ZeroMQ (slides and video)
It looks like the Slideshare Flash embed is causing it, since it's the only one I opened and almost got my MBP flying.
teoruiz··on Disaster: MySQL 5.5 Flushing
How is this different in MySQL 5.1?

From the article I get the impression that this is a new problem introduced with 5.5.

teoruiz··on The Costs of Bookmarking
It would be enlightening to know a bit more about the actual server architecture of the site. I understand that the storage footprint per user for a bookmarking site is quite big[1], but I still think $2k for 15k users is a fairly high hosting bill.

[1] Since they offer full archiving of bookmarked websites to their premium users.

teoruiz··on Chef on steroids
I know what you're talking about, really.

My piece of advice: use OpenVPN for remote workers and even for connecting those "public" servers outside your production network.

It's really worth it.

teoruiz··on Chef on steroids
What I don't get is why their Chef server has to be publicly reachable at all.

Shouldn't it be available only through their internal, private network?

I might be missing something here.
