The Herding Code 60: Spark View Engine with Louis DeJardin podcast just went up. Really fun group of guys. Interesting process they use to record also and seemed to work really well. I can just never get used to the sound of my own voice.
This is an open question really for people that make, use, or host ASP.NET apps… When you’re choosing a technology stack how important are memory pressure concerns?
So if you’re looking at adding automapper, or nhiberbate, or ioc xyz, you’re obviously going to be thinking about impact to CPU and memory.
And there are two type of memory impacts: load-and-hold and burn-rate (or memory pressure). The first is relatively easy to say you’re using ten megs of one-time cost memory in each appdomain once it’s initialized and warmed up. The other’s a bit more subtle – if a tool goes through a two megs of object, string, collection, buffer memory in a request – and say you’re tooling along with bursts of 25 req/sec – then 50meg/sec means you’ve given the garbage collector a gig of ram to recycle every 20 seconds. Numbers and needs vary but you get the idea that high burn rates end up causing a CPU tax to be paid affecting the net power availabe.
But on the other hand dotnet is a high level language, and a lot of there types of things are developer productivity tools – not performance tool – so they will *always* have measurable increase in cost. But in the most extreme cases, like from he point of view of a hosting company, you could almost assume that memory efficiency is directly proportional to hardware, space, and power costs per client…
Not that it’s a black and white situation, of course, but at what point are the conveniences and strengths of a library outweighed by the cost of using it? Of course it’s always difficult to weigh something subjective against something quantifiable.
But what’s your take on that?
The first blog post was keyed in from a mobile phone before new employee orientation, so I thought I would take a moment to write a more thoughtful post about the first few days. Well, maybe not more thoughtful… But at least a post that has some links and images in it.
For example, Building 42! My new home. I swear walking into the campus this morning I couldn’t keep the grin off my face.
Let’s see… What else is there. Ah! There are people in the building! To name a few there’s Bertrand Le Roy, Renaud Paquay, Bradley Millington… Ah, well. I’m not having much luck finding a public internet presence for a lot of people so I’ll leave off with the naming of names in case they prefer anonymity. There’s also people like Scott Guthrie and Phil Haack but that would be like pointing out the fact there are roads and trees around the building.
I’m actually feeling really good about the decision to join Microsoft. Met the team, surrounded by blindingly smart people, workstation fully installed, two beautiful monitors showed up today, getting a handle on where the project is at and where it’s going. End of the second day and it’s time to head home now.
It’s another one of those self-titled Where’s Lou posts today! So – where’s Lou now? New employee orientation in Washington! And Brenda’s still in Florida at the moment so the DeJardin household is about as geographically distributed as we’ve ever been. :)
The big news today is I’ve accepted a position at Microsoft, which is the final realization of an ambition of mine which started a year and a half ago. What hooked me then was watching the open style of development the ASP.NET MVC team was embracing and the great results and positive community feedback they were getting. I though to myself, if there was someplace you could choose to work that would be it.
I should add I’m not on the MVC team, but since I don’t know what’s public knowledge yet or not – please forgive me being vague.
Plus if anyone’s curious this doesn’t change the status of Spark regarding license, source, distribution, etc.
But yeah! Exciting! I have to finish up now and grab some coffee and prepare myself for a day of paperwork and hr presentations. Woohoo!
