Michael Still: The Martian

Wed, 2014-12-31 12:29

ISBN: 9780091956141


I bought this book because of a review I saw online recently, and I have to say I loved it. Its interesting, humorous, and a generally fun read with a story line that I haven't seen before. Its refreshing to encounter a new author who has some genuinely new ideas to explore. I highly recommend this book.

Michael Still: A quick walk to Tuggeranong Trig

Tue, 2014-12-30 22:29
This one was a super quick walk on the way to the hardware store. As well as the trig point, there was a defunct radio repeater at the top of the hill -- I believe this one was for the old analog Police radio network.

Michael Still: A walk around Mount Stranger

Sun, 2014-12-28 18:28
This is a walk around another hill a short drive from my house. The track was less well defined this time, so more bush bashing. There were these star pickets with white caps along the way which marked a join between two fire trails -- I think they indicate where fire trucks should go if they need to, but I am guessing. Bagged another trig point this walk as well.

I've been doing a lot more wood work recently, and I decided I wanted to write that up somewhere. Instead of posting it here, I also wanted to play with wordpress as an alternative hosting solution. The wood working is therefore being blogged on a new site, So far I've made a Thien Baffle cyclonic separator to stop my dust extractor filling with planer shavings, as well as documenting the process of making home made vanilla essence with turned bottle stoppers for Christmas. Oh, and I found a source of cheap high quality bar clamps in Australia.

Not too bad for the week before Christmas I don't think.

Michael Still: Walk up Tuggeranong Hill

Sat, 2014-12-27 10:28
I've had a hankering to do a bush walk for an while, and so I spent some time yesterday walking up Tuggeranong Hill. This was a really nice walk -- the access road for the ACTEW substation provides parking with shade from trees, and its very very close to my house. The entrance to the fire access road for the broadcast repeater at the top the hill isn't well marked, so I ended up going the long way. I think this made the walk more fun to be honest.

Penguin Dinner at MOTAT, Wednesday, 14th January from 6pm.

This year the steam-punk themed Penguin dinner will be held at Auckland’s MOTAT (Auckland's Museum Of Transport And Technology). With its traction engines, Victorian village, trams and trains makes it so easy to imagine Jules Verne or HG Wells wandering around creating their stories of futuristic wonder!

If getting dressed up in Victoriana or Steapmunk is your thing then this is the place! We’d love it if you’d like to dress in costume and show off your gadgets for the occasion, the more quirky and fantastical the better! It adds a certain air to the evening, however it is not mandatory.

MOTAT is a local favourite equipped with great facilities in a unique location, so we can be sure of a night to remember!

Professional Delegates Networking Session (PDNS) at Sweat Shop, Thursday, 15 January from 6.30pm.

The PDNS is being held at the newly-renovated Sweat Shop - a micro brewery with a philosophy around championing its staff - claiming to be Auckland’s hardest working bar. This destination mega-venue boasts one of Auckland’s largest outdoor decks and garden bar that really sings in the summer.

For the PDNS LCA 2015 will be taking over the venue for the whole night, so we will open the bar to all of our delegates after 8.30pm. UPDNS welcome!

Andrew Pollock: [life] Day 330: Christmas

Fri, 2014-12-26 22:25

Zoe slept all night, which was nice. She woke up at like twenty to five, needing to go to the toilet, and afterwards claimed that she'd checked for Santa and he hadn't come yet. I thought the jig was going to be up for sure, given that the presents were all out.

I managed to get her back to bed and she slept until 6:30am, which was a much more civilised time to be opening presents.

After opening presents, and breakfast, Anshu prepped the dish she was taking for Christmas Day lunch at my parents, and we headed over there.

My sister called and asked me to get some ice along the way. 7 Eleven were obviously anticipating a run on ice, because they had multiple insulated pallets of party ice bags. It was slightly crazy.

We had a nice Christmas Day lunch with my entire immediate family, which was a bit of a first since I've been back in Australia. Zoe got along really well with one of my brother's step sons, and generally had a good time.

After lunch, we headed down to Palm Beach for a quick catch up with some more family. Zoe had a nap along the way, and then we headed back to drop Zoe off at Sarah's place.

Anshu and I went back to my place, and we went for a nice evening stroll to walk off the Christmas lunch.

Andrew Pollock: [life] Day 329: Christmas Eve

Fri, 2014-12-26 19:25

I didn't have an awful lot planned for the day. Zoe finished watching the Nightmare Before Christmas, after she was dropped off, an then we made a bunch of dips for Christmas Day lunch.

Zoe really enjoys helping me in the kitchen, and today was no exception. She also has taken to helping with the washing up, and loves putting on my washing up gloves, so we made all of our dips together, and then she lost interest when it came time to make the plum pudding, so I did that myself.

Kelley had told me about a Christmas pantomime called Spaced Out Santa, on at the Studio Theatre and Cafe over at Morningside. I didn't’t even realise there was a theatre over there. They had tickets, so I thought that’d be something different to do.

We biked over there, via the post office, so I could deposit an offline donation I'd received for Decembeard.

We got to the theatre pretty early, and the "cafe" part of it was rather tiny, but we managed to snag a table. We had a drink and a snack while we were waiting for the theatre to open.

The theatre itself turned out to be not a lot bigger than the cafe. It was probably about 10 seats wide. We managed to get into the second row from the front. The play itself was nothing spectacular, but Zoe seemed to enjoy it. Most of the actors were children, and I thought they did quite a good job. It was hard to tell if the singing was lip synced or not.

Zoe was hungry by the time we got out, so after some photos with the actors, we grabbed some lunch nearby and then biked home.

I can't remember what we got up to in the afternoon, but Anshu came over, and we had some dinner, and then Zoe got all ready for bed, and we went for a drive around the neighbourhood to check out the Christmas lights. It was really nice driving around with some Christmas music playing on Pandora. I really like the Bing Crosby channel. It really helped set the mood.

Zoe has been super excited about Christmas this year. She's been counting down the sleeps until Christmas, and was very excited to leave out some egg nog, a mince pie and a cookie for Santa, as well as some water and carrots for the reindeer. I had just as much fun making them all look eaten. It really is a lot of fun looking at Christmas through the eyes of a child.

Francois Marier: Making Firefox Hello work with NoScript and RequestPolicy

Fri, 2014-12-26 15:37

Firefox Hello is a new beta feature in Firefox 34 which give users the ability to do plugin-free video-conferencing without leaving the browser (using WebRTC technology).

If you cannot get it to work after adding the Hello button to the toolbar, this post may help.

Preferences to check

There are a few preferences to check in about:config:

  • media.peerconnection.enabled should be true
  • network.websocket.enabled should be true
  • loop.enabled should be true
  • loop.throttled should be false

If you use the popular NoScript add-on, you will need to whitelist the following hosts:

  • about:loopconversation

If you use the less popular but equally annoying RequestPolicy add-on, then you will need to whitelist the following destination host:


as well as the following origin to destination mappings:

  • about:loopconversation ->
  • about:loopconversation ->
  • about:loopconversation ->
  • ->
  • ->
  • ->
  • ->

I have unfortunately not been able to find a way to restrict to a set of (source, destination) pairs. I suspect that the use of websockets confuses RequestPolicy.

If you find a more restrictive policy that works, please leave a comment!

Binh Nguyen: Music Players, Production, and Experimentation - Part 5

Thu, 2014-12-25 20:56
Updated and added a few more playlists to my YouTube account.
  • Alternative-Hip-Hop-23-Dec-14
  • Classic-Disco-24-Dec-14
  • Classical-19-Dec-14
  • Foreign-Hip-Hop-and-R&B-19-Dec-14
  • Lounge-24-Dec-14 overlaps Chillout-4-Dec-14 because style is very similar at times
  • Latin-and-Tango-4-Dec-14 has become Latin-Chillout-and-Tango-4-Dec-14

    After the recent end of production of the Apple iPod Classic it's become clear that the total number of options available in the high capacity digital music department have dwindled drastically (everyone is basically going to Flash or SSD based storage). There are some options from Fiio, an extremely option from Sony, plus using smartphones with support for high capacity flash based storage. If you're willing to buy used products other options may be the Tonium Pacemaker or old iPod Classics (they're selling for multiples of what they were selling last at retail now on eBay and Gumtree).

    Another option are high storage wireless based devices.

    Been struggling with sound engineering of late. Have wondered whether or not it's simply easier to go for transiest shaper VST's across the board.

    Someone questioned why it seemed easy for me to improvise. I was curious about this as well. I think for the most part it's been about listening to heaps of music since I was young. having major struggles of late how to relate percussion to melody. The best music I've come across seems to have tracks and sections which blend perfectly  into one another and where the relative complexity and tempo remains roughtly the same. A bigger toolkit (software or hardware) also helps. Look at work of 'Groove Armada', 'Artful Dodger', and 'Kaskade' and you'll understand what I mean.

    A lot of software allows for automated scale selection (useful for me because I tend to select notes based on ear rather than selecting a key first). For those who don't who just prefer the old fashioned mechanism please consider the, 'circle of fifths'.

    Think about use of Melodyne and Antares Auto-Tune for easier composition if you're lazy. Record whistling or singing as a 'WAV'. Import it into Melodyne and then convert the notes into MIDI for import into Ableton or other DAW software.

    Some interesting stuff I've come across recently. Possibly worth reworking/remixing them (looking around for good stems for remixing but am willing to work with existing songs if necessary).
    • Nice track but could have really done something with some note changes here and there. Strange use of panning at times, bit muddy, could have been clarified a bit in multiple frequency ranges. Could have done with master bus (or simply another layer) over the top to add some common effects to the overall track that are common to Latin and Tango tracks (Vinyl distortion, bitcrushing, equalisation, compression, etc...). Some sections don't blend into one another as a stronger song should, could be interesting for samples. 
    • Great overall. Some beautiful sections but a little bit disjointed. Bridges (personally, currently struggling with this) into breakdowns use heavy delay, reverb. Breakdowns similarly awkward at times (feel and emotion is just way off). More active strings/harmonica in parts, realy bring out the best in the musician/clip/instrument in question. Rain effect possibly replaced with heavy vinyl distortion effect? Just strange with that muddied sound. Bring up velocity or mixing volume of the piano in some parts? Better use of velocity/dynamics in some parts. Could have used some light scratching in some sections and some glitching if you going for an Alternative Hip Hop and Latin feel to it, made more use of panning and other effects to create better atmosphere. The best tracks that I've come across you can often close you're eyes and you're sitting right in front of the ochestra or band itself. You can't do that here. Ripe for sampling or remixing.
    • Ripe for sampling/remix... Heavier percussion in sections. Overlay scratching in parts. Some glitching. Perhaps electrical guitar over top. Vinyl distortion, bitchrushing for greater character. Really bring out some instruments and dynamics of them... Aware that lazy feel is common to this particular style/genre of music though.
    • Overall nice, downtempo track. Slow down vibrato/tremolo rate on some synthesiser sections. Suffering from distortion in the mix in the lower end bass and percussion area. Could have done with some extra complexity/variation in the percussion/synthesiser pad area. Am using monitor style headphones (Audio Technica ATH-M50X) so believe it may be the mix rather than equipment. Deals with high frequency harshness nicely. Feels like, low pass (or multi-band) filter, EQ, compressed, etc... Extra reverb plus some delay across the board on the bus to emphasise atmosphere?
    • Lacks oomph, character. A bit lost at times but that is particular to this genre. Greater dynamics across the board. Extra complexity on percussion, staccato shorter, more sincupated rim. Violin string section slightly more active at times. Clarify sound, enhance detail or is that just this particular copy?
    Looking to try some remix competitions. Looking for stems... that there may be a lot of restrictions depending on where you get the stems from. Also that many competitions force you to forfeit right to royalties. You may get prizes/recognition though.

    Andrew Pollock: [life] Day 328: Park fun

    Wed, 2014-12-24 15:26

    I didn't have a lot planned today, except for showing my first customer my favourite food wholesaler at around lunch time, so after Sarah dropped Zoe off, we gave her free reign over what we did.

    She said she wanted to go to the same park we went to last time, which I misinterpreted as Love Street park in Bulimba. So we set off on foot for the park.

    It turned out she really wanted to go to the West End park again, which was fine, because we could go there in the afternoon after lunch. At the Love Street park, we ran into one of the boys who will be going to her school next year, who went to her day care last year, and one of the boys from her Kindergarten, so that was nice to run into some familiar faces. It was while we were at this park that I received the sad news that Bryce had passed away.

    After a bit of a play in the park, we walked back home again, and drove over to West End, picked up my customer, showed her the food wholesaler, dropped her back at work and then returned to the food wholesaler to grab a few bits and pieces and have some lunch.

    After lunch, we went to the park at West End, and then we went back home again.

    Anshu went home, and then I put the Nightmare Before Christmas on for Zoe, which she watched until Sarah came to pick her up.

    Since I've been failing miserably to go for runs in the morning, I thought I'd try going for an evening run, so I did an atrocious 5 km run.

    Andrew Pollock: [life] Day 327: A trip to the Museum and Science Centre

    Tue, 2014-12-23 17:26

    Zoe slept all night (for a change), which was nice.

    We hadn't caught up with Chloe for a while, so I'd made plans with Kelley to spend the day at the Science Centre. Anshu was on Christmas holidays from work, so she tagged along with us as well.

    We all caught the bus in, along with Chloe's older sister.

    Before lunch, we all went to the Science Centre, and after lunch, we did the rest of the museum. The girls had a good time together, and Zoe seems to get along well with Chloe's older sister, Emma too, which is nice.

    Kelley had to go to the Valley to get some stuff, so we parted company at the bus stop and took the bus home.

    Laura dropped by with Megan and her little sister, not long after we got home, to drop off a Christmas present for Zoe from Megan, so the girls did a gift exchange and had a little play date.

    They left just before Sarah arrived to pick up Zoe, and Anshu and I took a walk down to Bulimba to check my post office box, and we discovered a new watering hole on Oxford Street, so we had a drink on the way back home.

    Tue, 2014-12-23 17:26

    I received a sad phone call this morning, while we were at the park.

    It was from Bryce's son, Russell, and he informed me that Bryce had had a fall and hit his head yesterday morning, and not regained consciousness before passing away today.

    It was a bit of a shock for me, given I'd only seen him on Monday of the previous week, and I'm so grateful that I did, because it had been several months since I'd last seen him.

    He was particularly weak and wobbly on his legs, so the fact that he had a fall wasn't particularly surprising, and in a lot of ways, it was a small mercy that he had a quick and presumably painless demise.

    He made it to 91, so that was a pretty good innings.

    I know he was looking forward to spending a few days with his family over Christmas, so it's a shame that he didn't get to have one more with them.
