macOS, Apple’s core
These days mark the 20th anniversary of Mac OS X, later renamed as macOS. Really the underlaying tech is the same, but the naming allows them to move past 10.X into other unexplored territories. There’s a lot of talk these days about Macs, specially after the introduction of Apple Silicon, which certainly is an exciting move. There was some years where there was debate over the tech world on whether Apple should drop the Macs and focus on iPads or iPhones. Because the old Personal Computer paradigm is dead, right? Nonsense. While… Read More
Notes about ShipItCon 2017
Disclaimer: I know personally and worked with a good portion of the conference organizers and talkers. I label them with an asterisk*. The ShipItCon finally took place last Friday. I think it’s quite impressive, given the short amount of time since announcing it and being the first edition, that was so well organized. The venue was very good (and fairly unusual for a tech conference), and all the usual things that are easy to take as granted (food, space, projector, sound, etc) work like clockwork. Kudos to the organizers. The conference was… Read More

Do not spawn processes on users requests
I’ve been playing recently an online game that has recently launched, that uses the following idea. When a user starts a match, it spawns a process in the server that acts as the opponent, generating the actions against the user. The game had a rough launch, with a lot of problems due it being played by a lot of people. And, IMHO, a lot of the problems can be traced to that idea. I see it’s a seductive one. If a user generates an interaction with the service that takes time (for example, a match for… Read More
All you need is cache
What is cache More than a formal definition, I think that the best way of thinking about cache is an result from an operation (data) that gets saved (cached) for future use. The cache value should be identifiable with a key that is reasonably small. This normally is the call name and the parameters, in some sort of hashed way. A proper cache has the following three properties: The result is always replicable. The value can be scrapped without remorse. Obtaining the result from cache is faster than generate it. The same result will be used… Read More

Future as a developer and the ever changing picture
A few weeks ago I came by a couple of articles my Marco Arment that share the theme of the current status of accelerated change within the development community as a way of stressing up, and being difficult to be up to date. After all, one gets tired of learning a new framework or language every size months. It gets to a point where is not funny or interesting anymore. It seems like two different options are presented, that are available for developers after some time: Keep up, meaning that you adopt rapidly each new… Read More
Requests per second. A server load reference
As there seems to be a lot of misconceptions about what Big Data, there are also not really a good baseline to know “how much is high load”, specially from the point of view of people with not that much experience in servers. If you have some experience dealing with servers, you will probably know all this. So, just for the sake of convenience, I am going to do some back-of-the-envelope calculations to try to set a few numbers and explain how to calculate how many requests per second a server can hold….

You can’t make One Perfect Final Decision
How to Make Technology Choices Truly awesome post by Steven Lott. The expectation of finality is the most disturbing: the expectation that someone can make OnePerfectFinalDecision. No technology choice is ever final. Today’s greatest ever state-of-the-art, kick-ass-and-take-names SDK may evaporate in a cloud of lawsuits tomorrow. Today’s tech giant may collapse. Today’s platform of choice may be tomorrows weird anachronism. … If you are really, really lucky, you may get big enough to have scalability issues. Having a scalability issue is something we all dream about. Until you actually have a specific scalability issue, don’t try… Read More
