sandfox | 12 years ago | on: Support for Test-Driven Devops
Writing code/recipes/etc for chef/ansible/puppet is no different to writing code for an application. Just because you think you have dictated (in code) that things should be a certain way does not mean that what will be executed or run.

nagios is awful :-), active checks are ultimately a dead end.
Heartbeat style stuff is where it's at.
You should definately check out sensu and riemann, (or hevean forbid if you really like node.js everything Godot)

"mission critical"...
sandfox | 12 years ago | on: FasterCGI with HHVM
because PHP is "slow" and c is "fast", just about anything thats written in PHP such as FastCGI parser would be daftly slow compared to a counterpart written in c or c++. Most people will not be prepared to sacrifice perfomance just for the sake having everything in PHP

You could (and many) do the same thing with git.

Hadoop cluster of of GPU + SSD'd up machines is not going to be cheap.... (but would be fun)
sandfox | 12 years ago | on: Intel - nodejs logging that plays nice with console.log
Why is your logging library handling log rotation? Also, not everyone logs to disk straight from process or at all.
sandfox | 12 years ago | on: Introducing Syngr, my attempt at an Standard Library for PHP
I know microbenchmarks are generally daft and horribly misapplied, but it might be worth showing/measuring the difference between using built-in procedural methods and your OO ones on some some example use cases to stop people speculating and just to make sure you aren't majorly shooting yourself in the foot perfomance wise for the benefit of a nice API.
All that aside, kudos!

They can (and often are), but some of the drones are capable of completely computer controlled take off and landing. I remember seeing somewhere that the human drone pilots caused more crashes when landing than the computer controlled ones.
sandfox | 12 years ago | on: ZooKeeper vs. Doozer vs. Etcd
Why shouldn't a 'devops' company complain about dependency? It's their domain completely. Treating anything as a "fact of life" is not going to make the problem go away...
And what about anyone out there trying to use them who isn't a 'devops' thingy. A painful dependency graph is going to be something that influences their decision on what tool they choose.
sandfox | 12 years ago | on: ZooKeeper vs. Doozer vs. Etcd
Just because you have tools ease dealing with dependencies, it does not mean that those dependencies and the cost of dealing with them has gone away. Easier to not have the problem instead of solving it...

only 30 mins of data retention... even AWS gives you 2 weeks at 5min resolution for free (albeit only stuff the hypervisor can measure because they don't run an agent, so no RAM etc).
sandfox | 12 years ago | on: Node.js incorrectly parses HTTP methods
It should probably be noted that:
a) you don't have use node's built in HTTP server (yeah, I know, nearly everyone will), you are more thn free to write your own or use one from it's module repository (npm)
b) The entire HTTP module is currently being over-hauled in the 0.11.X development branch and the changes should appear in the stable 0.12.x releases.
Out of interest has anyone seen what other web servers support for these more 'esoteric' verbs is like?
sandfox | 12 years ago | on: Push Notifications to Mobile Devices Using Amazon SNS
well, they do give a million free push messages a month to start with which slightly skews it.
"1 Million FREE Push messages/month. $0.001 per additional Push message"[1]
sandfox | 12 years ago | on: Push Notifications to Mobile Devices Using Amazon SNS
I wonder how long till AWS provides some form of realtime websocket/whatever connection service. (I admit it will be some time before things are stable enough to make it sensible for AWS to get involved).
This marks as interesting expansion nonetheless. Probably need to work out what extra cost of this is like (pretty hard to compare though)

sandfox | 13 years ago | on: Sign up for the SICP Blitz in London happening in June
Errmmmm don't think anyone is offended by the word blitz, or ever has been. It's a pretty common term over here (UK) to describe a period of intense activity of any kind. Everyone from soldiers to school teachers use it.
e.g we need to blitz the sink - we need to clean it thoroughly and/or quickly.

Why not just plant lots of explosive devices WITH a trigger mechanism... make the numbers game work for you :-)

Pedant time! ssh is just one of many transports that git can use.

Also side rant. To all non-londerners, Tech City / Silicon Roundabout is an abstract concept that doesn't actually exist in any concrete form. Unless someone told you, you wouldn't even notice you were passing through it. Infact the only remotely "tech looking" building is satellite company Immarsat's HQ office, and IIRC they were around long before "tech city" had been dreamed up.
