Analog

Analog doesn't understand IPv6. It will complain about 'domain not given'. Below a workaround;

• ipv6tofakehost.c
  Convert the IPv6 addresses into fake hostnames with fake tld '.ipvsix'. So '2001:db8:1234:1::1' becomes '1.z.1.1234.0db8.2001.ipvsix';

    cat some_log | ipv6tofakehost > some_other_log
      

  Do this before running Analog.
• fakehost2ipv6.c
  After running Analog do the opposite with the HTML page generated by Analog. So '1.z.1.1234.0db8.2001.ipvsix' becomes '2001:db8:1234:1::1';

    cat Report.html | fakehost2ipv6 > index.html
      

Put SUBORG *.*.ipvsix in your Analog config. Analog then neatly categorises unresolved IPv6 addresses;

And by /48;

ALSA (MIDI)

• Aseqnet
  • Aseqnet6
    Messy quick and dirty modifications to Aseqnet;
    • Support for IPv6.
      Dual stack only! It won't work on systems which insist on separate IPv4 and IPv6 sockets!
    • Nagle disabled, quickack enabled.
      This results in a noticeable reduction in latency.
    It's based on the Debian version of aseqnet. NLS has been disabled. Look for my initials (RvdP) to see what's different.
    Compile with -lasound.
  • A patch which just disables Nagle and enables quickack. Apply and run make.
  • A patch which does both.
  • A patch with a IPv4 only option. Debian packages based on this patch (not yet tested).
• Raw2seq
  Converts ALSA's SND_SEQ_EVENT_CONTROLLER into SND_SEQ_EVENT_CONTROL14, SND_SEQ_EVENT_NONREGPARAM and SND_SEQ_EVENT_REGPARAM.
  Compile with -lasound.
• More to come.
  I'm working on more ALSA (MIDI) related stuff. Including a device which converts 'physical' slider positions into MIDI messages. These MIDI messages can then be used to move sliders on your screen.

CSV to TSV

Converts Comma Separated Values to Tab Separated Values;

• Commas and quotes in fields are retained.
• Multiple quotes ("") are converted to single quotes (").
• Tabs are converted to spaces.
• Wrapped fields (',"Foo <End-of-line> Bar",') are unwrapped ('<Tab> Foo Bar <Tab>').
• Both Linefeed and Carriage-return - Linefeed end-of-line input are supported (output is Linefeed only).

Based on Comma-separated values on Wikipedia.

Medical

Menarini Read

menarini-read
A modified version of the Recvtty program used to read data from a Menarini V-Sight blood analysis machine.

Skyla Read

skyla-read
A modified version of the Recvtty program used to read data from a Slyla VB1 blood analysis machine.

Ntpeval

ntpeval.c
Program to check the quality of NTP synchronisation; When Garmin looses NMEA sync it's PPS will start to drift.
Output with the '-d' option;

0 +ntp0.nl.net  -0.002000
1 -ntp1.oma.be  0.021000
2 -ntp2.oma.be  0.005000
Cnt: 3
DCF: 0.422000
PPS: 0.001000
Avg: 0.008000

Recvtty

recvtty.c
This program dumps data from a serial port in to a file. The tty is set to raw mode and the data is eight bits, no parity one stop-bit (8N1) and uses RTS-CTS handshaking. The program doesn't need DSR or DCD but can monitor these if you want.

Sndnul

sndnul.c
This program sends null chars to a serial port at 115200 bps.

Search

Rob's search thingy.
My indexer and search engine.
There is also a crawler.

Squid

Squid redirector with RBL support

Utundup

When cut and pasting text from Xdpf, it thinks it should convert the data to UTF-8, even though the data already is UTF-8. For instance, the degree sign ('°') (mbs '\xC2\xB0') gets converted into '°' (mbs '\xC3\x82\xC2\xB0').
utundup.c converts the data back.

Misc

• Cook your own CRC
• uspell.sh Multiple language spellcheck script.
