Re: Online database for music library

If you're comfortable with it, you can back end LO Base onto MariaDB, PGSQL, Firebird, etc. Use it to build your schema, migrate the data, then layer an interface of your choice on top.

Re: Anyone use Forth, or have experience with it?

I think you should definitely learn C at some point, but I encourage you to perhaps use Python at first instead. C is great as an alternative to assembler, but not so good as a beginner language (in my opinion). You might find some other domain focused languages useful depending on what field you se...

Re: Transformer Size for a Dedicated Audio Computer?

Check the power factor on the transformer, if it's say 0.7, then 1000kVA will be good for about 700W. I think you mean 1000VA rather than 1000kVA :o . But as bigfoot said, you rate the transformer for it's output load at unity. And any PC or laptop built in the last 10 years will have PFC in the su...

Re: Transformer Size for a Dedicated Audio Computer?

Check the power factor on the transformer, if it's say 0.7, then 1000kVA will be good for about 700W. No. Transformers are rated in VA. If the load on the transformer has, say, a 0.7 lagging PF and consumes 700W of real input power, it's supplying 1000VA of apparent power. The same transformer coul...

Re: WD My Book External Drive - work as NAS?

What type of router, what version of firmware?

The router might only support USB printers in your firmware, or might only support certain filesystems.

Re: Front panel audio noise

Check if the front panel board has EMI filtration. If not, you can build and install a standard EMI filter as noted in the Intel HDA design spec. Not every motherboard has filtration.

Re: Good sound solution for my home theatre setup?

HDMI is digital, and bits are bits are bits. Spend some money on a sub and perhaps some acoustic material for the walls instead.

Re: Custom Built Home Router

I just installed a WR1043ND which I flashed with OpenWRT. I think it would be appropriate for your purpose. Lots of performance to run Snort. USB port for extra storage to dump log files to. I also have a WL-520gu kicking around which I ran for years so I think you'd be happy with an ASUS unit as we...

egrep ^username /etc/passwd


Otherwise, you're getting all matches in the password file, regardless of position. Useful for people with names like Ed.

Well, you can fix it yourself.

Or you can use a drive tuned for RAID environments.

Re: your video tearing This problem is certainly a driver issue. If you can tell us which video card your computer is using we are likely to be able to provide some advice on how to work around or eliminate the problem. Also, VLC has known issues with certain HDA codecs. Workarounds are also availab...

Re: Help with homework

m = p* i/(1-(pow((1+i),-t))); Donuts has it correct. You can use t in years if i is APR (the proper annual rate) and you'll get a yearly payment. Interest has to be fractional, so make sure you divide by 100 at some point. I believe roundoff won't be a problem for realistic interest rates. Hmm... ta...

Re: Decoding Dolby Digital

Sorry about misunderstanding earlier, I didn't have a clear picture of what you were getting at. It seems what you'd really like is some kind of driver shim which intercepts SPDIF and decodes it if it's Dolby Digital or maybe DTS as well. I can't say for sure that there isn't something which would d...

Re: Decoding Dolby Digital

It should be possible to capture the DD bitstream from a TOSLINK input on your computer (if it has one) and then retransmit on SPDIF Coax. By the way, SPDIF Coax can be rigged on any motherboard with the right header. Or, you can decode the DD bitstream on the computer via software and output on 3 a...
