Introduction: I try to keep this blog targeted and on topic. So even though I may be thankful for the song of the tinniest sparrow at sunrise , I'll save you from all that. It's hard to tie scalability and the giving of thanks together, especially as it sometimes occurs to me that this blog may be a self-indulgent waste of time. But I think I found a sentiment in A New THEORY of AWESOMENESS and MIRACLES by James Bridle that manages to marry the topic of this blog and giving thanks meaningfully together: I distrust commercial definitions of innovation, and particularly of awesomeness. It’s an overused term. When I think of awesomeness, I want something awe-inspiring, vast and mind-expanding. So I started thinking about things that I think are awesome, or miraculous, and for me, it kept coming back to scale and complexity. We’re not actually very good about thinking about scale and complexity in real terms, so we have to use metaphors and examples. Douglas Adams writes s
2 0.94432038 809 high scalability-2010-04-13-Strategy: Saving Your Butt With Deferred Deletes
Introduction: Deferred Deletes is a technique where deleted items are marked as deleted but not garbage collected until some days or preferably weeks later . James Hamilton talks describes this strategy in his classic On Designing and Deploying Internet-Scale Services: Never delete anything. Just mark it deleted. When new data comes in, record the requests on the way. Keep a rolling two week (or more) history of all changes to help recover from software or administrative errors. If someone makes a mistake and forgets the where clause on a delete statement (it has happened before and it will again), all logical copies of the data are deleted. Neither RAID nor mirroring can protect against this form of error. The ability to recover the data can make the difference between a highly embarrassing issue or a minor, barely noticeable glitch. For those systems already doing off-line backups, this additional record of data coming into the service only needs to be since the last backup. But, bein

The minibus can be fully recharged in fifteen minutes, unlike battery vehicles, which typically takes hours to recharge. Update 15: How to Make UAVs Fully Autonomous . The Sense-and-Avoid system uses a four-megapixel camera on a pan tilt to detect obstacles from the ground. It puts red boxes around planes and birds, and blue boxes around movement that it determines is not an obstacle (e.g., dust on the lens).

Introduction: From their website : There are a number of times in which you find yourself needing performance data. These can include benchmarking, monitoring a system's general heath or trying to determine what your system was doing at some time in the past. Sometimes you just want to know what the system is doing right now. Depending on what you're doing, you often end up using different tools, each designed to for that specific situation. Features include: You are be able to run with non-integral sampling intervals. Collectl uses very little CPU. In fact it has been measured to use <0.1% when run as a daemon using the default sampling interval of 60 seconds for process and slab data and 10 seconds for everything else. Brief, verbose, and plot formats are supported. You can report aggregated performance numbers on many devices such as CPUs, Disks, interconnects such as Infiniband or Quadrics, Networks or even Lustre file systems. Collectl will align its sampling on integral sec
