I have migrated my blog from WordPress to hexo, but the old URLs need to be permanently redirected. I'm using NGINX as my web server, so I set up some rules for redirecting the old posts to the new URLs. It's a bit tricky because WordPress used query string param for identifying the page, but it can be sorted out using if and the NGINX $arg_ variable. In order to generate these rules, I wrote a simple node script that runs through the exported Markdown files from WordPress. Markdown files were exported using Jekyll Exporter plugin.)

Quick script for extracting gps data from the Tracker GPS app

First export data from app com.eofster.tracker using something like iPhone Backup Extractor (http://supercrazyawesome.com/)

mkdir tracker-extract && cd tracker-extract

npm install csvtojson
npm install gps-to-gpx

(cd 'com.eofster.tracker/Library/Application Support/com.eofster.tracker' && sqlite3 -header -csv Tracker.sqlite "select * from ZTRACKPOINT order by ZTIMESTAMP;" > out.csv)

Create index.js:

var Converter = require("csvtojson").Converter;
var converter = new Converter({});

const createGpx = require('gps-to-gpx').default;

//end_parsed will be emitted once parsing finished
converter.on("end_parsed", function (jsonArray) {
   //console.log(jsonArray);
   const converted = jsonArray.map(pos => {
     return {
       latitude: pos.ZLATITUDE,
       longitude: pos.ZLONGITUDE,
       elevation: pos.ZALTITUDE,
       time: new Date((pos.ZTIMESTAMP+978307200)*1000).toISOString()
     };
   });

   const gpx = createGpx(converted, {
     activityName: 'tur',
     startTime: converted[0].time,
   });

   console.log(gpx);
});

//read from file
require("fs").createReadStream("out.csv").pipe(converter);

Run:

node . > out.gpx

XBMC (now Kodi) has always had a tendency of leaking memory, so that it will eventually thrash and crash. My simple solution to this is to run xbmc inside a for loop instead of directly (just run the script from .xinitrc):

xbmc_angel.sh:

#!/bin/bash
while [ 1 ]; do
        xbmc
        nohup sleep 10
done

...And add the following to the local XBMC user's crontab:

0 4 * * *       killall xbmc.bin

This will kill XBMC every night at 4 o'clock. And give you a fresh XBMC every day!

The new Pepper Flash plugin broke my old script for listing/downloading cached flash/flv videos.

Here is a new script. Uses sudo because the /proc/$PID/fd directory is root only. This solution is based on silviot's solution here: http://superuser.com/questions/622606/how-do-i-save-the-buffered-flash-video-on-linux.

#!/bin/bash
for FLASHPID in $( pgrep -f chrom ) ; do (for FLASHFILE in $(sudo ls -l /proc/$FLASHPID/fd|egrep "(/tmp/Flash|Pepper Data)" | sed -r 's/^.* ([0-9]+) -> .*$/\1/'); do echo /proc/$FLASHPID/fd/$FLASHFILE; done ); done

Then you can just copy the file into home, like:

cp /proc/26493/fd/30 ~/

Det er overraskende enkelt å lagre video fra VGTV.

Jeg har laget et python-skript som automatisk henter ut adressen. Last ned skriptet her.

Kopier lenken til videoen du vil ha, feks. http://www.vgtv.no/?id=33283&category=1

Bruk python fra komandolinja og hent ut adressen ved hjelp av skriptet, eks.:

python vgtv_url.py http://www.vgtv.no/?id=33283

python.exe vgtv_url.py http://www.vgtv.no/?id=33283

(Windows CMD)

Du vil så få en rtmp:// URL. Åpne denne i VLC og fortell VLC å automatisk lagre videostrømmen.

Eventuelt, bruk VLC eller mplayer på kommandolinjen med en av disse one-linerne:

vlc "$(python vgtv_url.py http://www.vgtv.no/?id=X)" --demux=dump --demuxdump-file=video.mp4

mplayer -dumpfile video.mp4 -dumpstream "$(python vgtv_url.py http://www.vgtv.no/?id=X)"

Gammel (manuell) metode:

1. Ta URL-en til en video, f.eks.: http://www.vgtv.no/?id=33283&category=1

2. Notér id (her: 33283)

3. Gå inn på: http://www.vgtv.no/api/?do=playlist&id=NOTERT_ID F.eks.: http://www.vgtv.no/api/?do=playlist&id=33283

4. Fra XML-filen, hent ut rtmp-adressen under følgende hierarki (prøv et vilkårlig location-element): <playlist> <trackList> <track> <location>

Åpne så denne URL-en i MPlayer. F.eks.:

mplayer -dumpfile video.mp4 -dumpstream rtmp://88.87.43.102/streaming/mp4:storage/compressed//33283/flash_1000.mp4

Dette kan også gjøres med VLC:

vlc rtmp://88.87.43.98/streaming/mp4:storage/compressed//33283/flash_1000.mp4 --demux=dump --demuxdump-file=video.mp4

Vent, og du har snart videoen på disk.
