The difficulty is that you are using a filesystem hierarchy to 'copy files' when you actually want to do a volume dump (block copy). Use XFS and xfsdump, or ZFS and zfs send, to achieve this. Copy with hard link preservation is es

The use of any sort of nuclear power with a well though out multi millenia waste storage system is irresponsible. Ideally this would be accomanied by a secret cult of priests of the atom, charged with defending the sacred temple sites fovev

Signal processing in javascript maybe, but webGL is a hardware accelerated native code module, so it can be fast. WebGL systems are actually very promising for a number of computationally intensive areas, such as medical imaging: http:&#x2

This is really cool. A nice explanation of using image FFTs is also given in the Image Magick docs: http://www.imagemagick.org/Usage/fourier/

I'd love to agree because rail is beautiful. However rail is even more over regulated than trucking. Also it requires massive capital investments, both in the rail system and operators to get economies of scale, which causes problems w

Please don't even bother trying to peddle your stuff on HN. No technical content, nothing open source, why are you wasting our time? If readers in interested in this area: http://googl.com/#q=acoustic+ray+tracing

Not exactly a dev board, and $500 price bracket, but possibly more practical for many: http://redpitaya.com/ If you want to interface with the real world it is great to get something where the analog part is done well. All

If all Post correspondents used SecureDrop to submit their stories that would be a start. One would have to assume that all the traffic going to the server is logged by the NSA and anyone else who can manage it. If the traffic volume is low

I'd really like to know if the core problem, the broken android security model (which allows escaping from firewall/vpn settings by activating another app) will be fixed. Will be interesting to see what the blackphone does.

Very, very hard, if you mean kernel threads running in parallel. However, if the other cores run separate kernel instances (machine partitioning, separate memory and everything) that would be more achieveable. UNSW call this the clustered m

An even better idea for developers is to reduce limits (memory, PIDs, file handles) and start triggering those rarely-used (or non-existent) error handling code paths. Also, I think I would prefer process sbrk failure to OOM killer activati

Actually a meteorologist isn't just massaging the data. Models often have know biases, eg under predicts rain when there is an offshore wind, or doesn't model complex local topography and gets mixing wrong, etc. Forecasters use th

I say old chap, I'm afraid you are being rather anglo-centric and what not. I have it on good authority they have weather in the heathen lands to the Far East. Why the Japanese built an 'Earth Simulator' with 10TB of RAM back

The truly paranoid worry that the processor will not execute instructions as they think it will. This ranges from timing irregularities from branch prediction and instruction re-order to bugs in CPU microcode or deliberate backdoors in the

It's a pity they don't have akamai/cloudfront or something, it seems they are getting crushed. So whomever is running 27 simultaneous downloads, please stop. You'll never read all those books.

I detest slideshare. The way they try to monetize and track me by making me log in to download the PDF. The dumb way they show the slides on a third of the screen and fill the rest with crud. So if you really don't want your slides rea

Great read. But I was disappointed that it didn't mention other password encryption schemes, i.e. Blowfish. www.postgresql.org/docs/8.4/static/pgcrypto.html
