Good times.

(For the record, I’m not against ads in web pages. To support good methods of advertising I tick the box in Adblock Plus which allows non-obtrusive advertising. But the BigPond miscellany makes the otherwise excellent and useful AFL website slow and annoying.)

I’ve added an IcyDock Duo Swap to the 5.25″ bay. I use its 3.5″ bay for rotating HDD backups, and its 2.5″ bay for the system SSD. Having the OS drive in a hotswap bay is pointless, but it kept the case neat.

There is a fifth SATA port on the motherboard, but to use a sixth drive I was required to use a SATA to eSATA cable and poke it out to the eSATA port at the back of the case. I also found the case fan a bit noisier than I liked, so I replaced it. Concerned by the possibility of buying an incompatible PWM model as warned by this article, I used a non-PWM fan and set the RPM manually.

In order to make the drives hot-swappable I was required to install a modified bios and alter some advanced configuration settings.

Ubuntu-server 12.10 is installed, along with Sick Beard, SABnzbd+, and Deluge. At some point it may also host an XBMC database, so to handle these services better I’ve upgraded the box to 8GB RAM.

Both AFP and CIFS are used to allow my MacBook and HTPC to connect to it with ease. I briefly played with NFS but couldn’t get the bindings and permissions to work correctly. I like that the client machines use their own native mechanisms, anyway.

I’ve also made it a printer server by installing CUPS, and I made it work for iPads by installing Avahi, roughly following this method.

I played around a bit with software RAID via mdadm (the advertised integrated RAID is only FakeRAID), and it works well, but ended up just going straight with the various HDDs I had sitting around. I don’t need redundancy, I just wanted backups of my documents and photos.

Local backups are made using rsync and rotating external HDDs in the DuoSwap. Automated external backups are performed using the excellent little tool encrb to upload encrypted data to a private server.

That’s about it.

Update: I have heard that 10.8.3 has solved this problem for some people, so I rolled back my changes and installed the update. No change on my monitor. Nevertheless, it’d be a good idea to update OS X before trying this, since it may fix the issues with your particular hardware.

I recently bought a MacBook Pro (with ‘Retina’ screen), but when I hooked it up to my Dell U2410 monitor via HDMI cable I was shocked by the poor picture quality. The contrast was all wrong and text was misshapen. No amount of calibration in the monitor or software would fix it.

Short answer: OS X thinks my monitor is a TV, and is using the YCbCr colour space rather than RGB. I had to override an EDID setting to force the RGB colour space, and it is now working correctly.

Long answer: I haven’t owned a Mac for a while and had forgotten how useless most of the “Apple community” is when it comes to anything that can’t be adjusted in System Preferences. Googling for problems with external monitors on MacBooks found dozens of threads on official and unofficial Apple forums, all full of people with the same problem. The most common responses from the Apple geniuses was to blame the monitor, despite assurances from the stricken users that the monitor worked beautifully in Linux and Windows, even on the same machine under Boot Camp.

“You just haven’t calibrated it!”, “You are just too used to Retina now!”, “You just need to buy a Thunderbolt display!” Apple people also like to solve problems by throwing more money at it. (I realise that owning a Mac makes me an Apple person, too. Hypocritical self-loather?)

My lucky break was reading that the current colour space was “YCbCr” when I was browsing the monitor’s settings menu. I was sure that it was using RGB when hooked up to my PC, so I started searching instead for forcing RGB mode in OS X. It didn’t appear to be available out-of-the-box, but I have had some experience in overriding EDID settings for similar purposes so I searched instead for that.

I found this thread on the EmbDev.net forums. Mr Schwarz, thanks very much. Your thread and script was incredibly helpful and informative. It was written to fix problems connecting an external monitor via DisplayPort, but it fixed my HDMI issue just the same. I’ve summarised the required steps below.

My last word is to wonder what Apple is playing at. It seems that this problem has been reported by a lot of people for a long time, and I expect it would require a fairly simple software update. Do they just not care about those using third-party components, or are they actively attempting to force people on to Thunderbolt displays?

How to force RGB in Mac OS X

1. Download the patch-edid.rb script from the forums thread above and put it in your home directory.
2. Connect only the external monitor(s) in question (I closed my MacBook lid, for example). The script will make override files for any connected monitor.
3. Type “ruby patch-edid.rb” in Terminal.
4. A new folder will be created in your home directory. Move it into the “/System/Library/Displays/Overrides” folder. If Finder tells you that you are overwriting an existing folder, consider backing it up first.
5. Restart your computer, enjoy your monitor.

To undo the changes, either delete the folder you had copied to the Overrides folder (if it didn’t already exist) or replace it with the folder you had backed up.

• scroll lock becomes caps lock
• caps lock becomes control
• control is… still control

I have successfully done this in Windows XP, Vista, and 7. There are numerous key-mapping programs around that do the same thing but since this is the only change I wanted to make, it was easier just to set it and forget it.

Here’s how to start using your caps lock key more often. Or less often, if you are a shouty, chain-email-forwarding great uncle.

Control

To set caps lock to act as control, and set scroll lock to act as caps lock:

1. Create a file with a .reg extension and insert the text in the block below (ensure that it ends with a new line).
2. Double-click on the file, select ‘Yes’, then restart your computer.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,1d,00,3a,00,3a,00,46,00,00,00,00,00

Backspace

Alternatively to set caps lock to act as backspace while still setting scroll lock to act as caps lock:

1. Follow the same process as above, but use the following code.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,0E,00,3a,00,3a,00,46,00,00,00,00,00

Undo

To undo either of the above changes by returning your keyboard to the default mapping:

1. Follow the same process as previously, but use the following code.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,3a,00,3a,00,46,00,46,00,00,00,00,00

The part of the world that does not legally kill its citizens is victorious! So, is removing an archaic form of justice the secret to Olympic success? It’s not quite that simple. The top two nations in the general tally are also in this illustrious list:

The USA and China give the off-with-their-heads mob it a great start, but they can’t compete with the sheer number of little-nations-that-could in this enlightened tally:

The source for the tally is ScraperWiki, and the source for the capital punishment stats is Wikipedia. I’ve given some countries the benefit of the doubt by including those who have “abolished in practice” on the side of no death penalty.

It’s been fun! See you again in Sochi 2014. I love the ski jump.

XBMC

Since 2004 my original Xbox has served as a cheap entertainment centre. Until last week it was running XBMC4Xbox, a branch of XBMC that has been built specifically for the console since the main project began to target newer, beefier hardware. However, the Xbox struggles with most high definition content, so to play such files I was forced to use my PS3 and the excellent PS3 Media Server.

As great as that software is, using the PS3 for any kind of media management after being spoiled my XBMC is a pain. I recently bit the bullet and bought a net-top computer in order to install XBMC and use it to play all of my content. I chose the Revo 3700 because it ticks a number of boxes – particularly its support for VGA-out. Most similar devices have dumped this feature, making them incompatible with my Sony Wega CRT.

XBMC comes in a number of flavours, but a third-party Linux distribution called OpenELEC appealed to me because it is built from scratch specifically for XBMC. It also provides a version compiled for the ION GPU used by the Revo. This means it boots quickly, runs efficiently, and is incredibly easy to install. For most setups this would have been the end of the story, but I had a specific configuration in mind.

Configuration

Although I require VGA for video, my Yamaha receiver takes HDMI and I was keen to take advantage of the benefits it has over optical audio. This is where I ran into trouble – if the HDMI cable was connected the system would assume that it was being used for video, and would switch off the VGA.

OpenELEC allows the user to edit the X.Org configuration by creating an xorg.conf file in a specific config folder. I found that I could specify that the graphics device (an NVIDIA ION2) should use the CRT display, but when I did that the HDMI would be disabled entirely – the HDMI indicator on my receiver would turn off. It seems that in order to use the HDMI audio, X needs to send HDMI video, too.

What I’ve done is simply enable the NVIDIA feature “TwinView”, and set its orientation option to “clone” mode. This means that the same video is being sent to both the VGA and HDMI outputs. I’ve pasted my xorg.config file below; in most setups just the Device section would suffice but I was required to flesh it out a bit more to accommodate my TV.

# X.Org configuration: /storage/.config/xorg.conf

# define the mode required by the TV
Section "Modes"
  Identifier "modes"
  Modeline   "1280x720" 74.250 1280 1330 1370 1650 720 725 730 750 +hsync +vsync
EndSection

# define the device and enable cloning
Section "Device"
  Identifier "device"
  Driver     "nvidia"
  Option     "TwinView" "true"
  Option     "TwinViewOrientation" "Clone"
EndSection

# define a monitor so that we can select the custom modes
Section "Monitor"
  Identifier "monitor"
  UseModes   "modes"
EndSection

# define the screen and select the mode
Section "Screen"
  Identifier "screen"
  Device     "device"
  Monitor    "monitor"
  SubSection "Display"
    Depth      24
    Modes      "1280x720"
  EndSubSection
EndSection

Extras

X could not retrieve the TV’s EDID, so I had to define a modeline manually. I found this by connecting my PC to the TV and using PowerStrip to set my desired resolution and calibration. The software then provided the “Modeline” above.

Finally, in order to use the correct sound device I had to set custom values in XBMC’s audio settings. These values were provided by Therio on the OpenELEC forums:

Audio output:       HDMI
Output device:      custom -> plughw:1,7
Passthrough device: custom -> plughw:1,7

Everything is now working perfectly.

The Brownlow Medal

• is an award given to an AFL player in recognition of a good season. It’s considered to be the highest individual award in the competition, which is more due to its history and status (not to mention how much the media loves to pump it up) than any other consideration.

• isn’t an accurate indication of the “best” player of the year. The winner is always among the best players and in some years we might agree that the winner was the very best, but that’s not too often.

Chris Judd is a champion and his great year has been recognised. Good, he deserves it. I’ve always been a critic of the Brownlow, though – not of the medal itself, but of what it’s held up to be. Footy followers think that it should always be awarded to the best player of the year (and they always claim know who that player is!) but there are two big problems that hinder it from happening.

Problem 1: The umpires cast the votes

The umpires have a lot to do during a match, and they spend most of it chasing after the ball. Consequently they see a lot of action from the midfielders, and may miss some of the more subtle parts of the game. They also have a different interest in the game than the average viewer, and they’re charged with finding the “fairest and best” player of the match, so they probably take things other than sheer brilliance into account. Finally, the Brownlow is an individual medal in a team game, which is always problematic. Individual skill needs to be recognised, but I think the way they execute their team plan should also be considered, and the umpire can’t possibly judge that.

Problem 2: It has a poor voting system

At the end of a game, the umpires allocate their 3-2-1 votes to three separate players. This is the case regardless of whether a match is marked by a big team effort, or whether a few players did all the work. There aren’t enough votes to go around – some good players miss out entirely, and sometimes three votes aren’t enough to measure the influence a player had on the game.

The Solution

We already have an award that does a pretty good job of finding the best player of the year, and it’s the AFL Coaches Association Champion Player of the Year. What makes this award so good is that it addresses both of the above problems. It’s voted by the coaches, who have the perfect understanding of how well each player filled their given role. They also know which opposition players caused them the most problems. Although the flashier players will usually still get more votes, this opens it up a little more to the less glamorous roles, like defenders.

It also has a reasonable scoring system. Each coach picks five players to award votes on a 5-4-3-2-1 scale. That’s a total of thirty votes between the two coaches. Sometimes the two coaches’ choices overlap, sometimes not. The high scoring system separates the best from the rest in a more definite way than the lower-scored Brownlow. It’s still not ideal, but it’s an improvement. It did a good job at ranking the best players this year:

2010 AFLCA Champion Player of the Year
114 – Dane Swan (Collingwood)
88 – Luke Hodge (Hawthorn)
80 – Joel Selwood (Geelong)
75 – Aaron Sandilands (Fremantle)
71 – Chris Judd (Carlton)
70 – Gary Ablett (Geelong)

But even the AFLCA put Judd in the top five for 2010, so those who claimed that Judd didn’t even deserve to make the All-Australian team can get stuffed.

Sad face

The stature of the Brownlow drowns out the other awards, and so everyone – the public, the media, the players – puts their faith in the Brownlow and demands that it be awarded to the clear player of the year. We don’t always see eye-to-eye on who that player is, but in 2010 everyone seems to agree that it was Dane Swan, so the knockers have been more vocal than usual. Swan did have a great year, and Brownlow night must have been a terrible let-down given that the media had already awarded it to him. But that doesn’t make Judd any less a champion: he had a great year, and he deserves his award. It’s a shame to see people attacking him with their disappointment.

The Brownlow simply isn’t the award that the public wants it to be. It awards something unique – something you can’t quite put your finger on – and it would be great if people recognised and appreciated that. It would also be great if the coaches award was elevated to a higher importance to fill the “best player” void. The TV networks wouldn’t go much on it – the count would probably be decided earlier in the evening and the winner would rarely be a surprise – but the public would get the result they want. And maybe they’d stop knocking champions for their success.

But that probably won’t happen as long as there are Collingwood supporters.

• Slow: I find that fast-forwarding or using the “scene search” functionality lags much more than when watching .mpg files.
• Not pretty: To my eye, .wtv files are blockier (on the PS3) than the .mpgs I create.
• Bigger: 3.5 hours of HD Sunday Night Football creates a .wtv file of around 20GB. After converting to .mpg the file is about 18GB. This is trivial with the cost of storage at the moment, but it’s interesting nonetheless.

The WTV format is relatively new, having replaced the DVR-MS format that Windows used previously. Windows 7 provides the functionality to convert .wtv files “back” to .dvr-ms files, and to do so is as easy as right-clicking the source file and selecting “Convert to dvr-ms Format”. This is crucial functionality since, while WTV is completely new, DVR-MS is based on the well-known ASF format. This makes it easy to retrieve the core MPEG2 data.

To produce a .mpg file from a .dvr-ms file, we can use ffmpeg from the command line:

ffmpeg.exe -y -i "showname.dvr-ms" -vcodec copy -acodec copy -f dvd "showname.mpg"

Here are the options explained (taken from ffmpeg’s documentation):

-y                  overwrite output files
-i filename         input file name
-vcodec codec       force video codec ('copy' to copy stream)
-acodec codec       force audio codec ('copy' to copy stream)
-f fmt              force format

Essentially I’m telling ffmpeg to copy the audio and video streams just as they are, and to put them into DVD format (MPEG2). It doesn’t perform any re-encoding, so it quickly produces a nice .mpg file that plays natively and perfectly on my PS3.

I quickly tired of having to complete a two-step process  to watch a TV show, and I wrote a batch script to do the lot at once. For each .wtv file in my Recorded TV folder, it will:

• Create a temporary .dvr-ms file from the .wtv file (using the core WTVConverter program provided by Windows 7)
• Create a .mpg file from the .dvr-ms file (using ffmpeg)
• Delete the .dvr-ms file
• Move the .mpg file to a different directory

To use this script just paste it into a .bat file and change the paths accordingly. You shouldn’t need to change the value of wtvconv.

@echo off

set recordedtv="D:\Recorded TV\"
set destfolder="D:\taped\"
set ffmpeg="C:\programs\ffmpeg\ffmpeg.exe"
set wtvconv="C:\Windows\ehome\WTVConverter.exe"

for %%f in (%recordedtv%*.wtv) do (
%wtvconv% "%%f" "%%f.dvr-ms"
%ffmpeg% -y -i "%%f.dvr-ms" -vcodec copy -acodec copy -f dvd "%%f.mpg"
del "%%f.dvr-ms"
move "%%f.mpg" %destfolder%
)

I have thought about having it delete the .wtv files, too, but I prefer to check that the conversion has worked before deleting them manually. On rare occasions the process has failed with no explanation, but simply running it again has done the trick.

A couple of caveats, now. I have found that recent versions of ffmpeg sometimes fail during conversion with “error, non-monotone timestamps.” I found a solution from another blogger, who suggested downloading an older version from here. I don’t know why or how, but this works for me.

Secondly – and seemingly only when converting high-def video – ffmpeg sometimes complains, “packet too large, ignoring buffer limits to mux it“, yet still appears to do the job correctly. I assume that this has something to do with the default buffer size used in DVD creation, but I haven’t found a way to fix it. It doesn’t seem to cause any problems, but for completeness’ sake I’d like the solution. Please let me know if you can help!

Finally, I anticipate the question, “why don’t you just use a program that records directly to .mpg?” Well, I have. I’ve used GB-PVR, for example, and combined it with a variety of multiplexers. To my eyes the quality has never matched the output produced by Windows Media Centre. This has more to do with the multiplexers than the application, of course, but I also prefer using Media Centre to browse and schedule recordings. This is the best solution I’ve found to suit my preferences (so far).

Most cricket fans know the story – after Australia beat England in an 1882 test match, a mock obituary appeared in The Sporting Times “in Affectionate Remembrance of English Cricket”. The final line of the obituary reads, “The body will be cremated and the Ashes taken to Australia”. Thus began one of the most enduring sports legends.

The obituary was a great joke, and English captain Ivo Bligh (later to become Lord Darnley) declared that he’d regain “the Ashes” when England toured Australia in 1882-83. He referred to “the Ashes” several times during the tour, and the Australian media ran with it. The term then fell out of use for twenty years before being cemented by English captain Plum Warner when he published How We Recovered The Ashes in 1903.

The Ashes legend was forty-five years old when the general public became aware of a certain urn. The following poem, appearing in The Cricketers Annual in 1925, indicates as much:

So here’s to Chapman, Hendren and Hobbs,
Gilligan, Woolley and Hearne:
May they bring back to the Motherland,
The ashes which have no urn!

(For the record, England was thumped 4-1.)

In 1927 Florence Bligh, widow of Ivo Bligh, gave the Marylebone Cricket Club a small terracotta urn that had been given to her husband some years prior. Although the details are disputed it is believed that a group of Victorian women, picking up on the “ashes” term used by the media, awarded him the urn after England’s series victory in 1883.

The urn was a personal gift to Bligh, and was later a personal gift to the MCC. It is known as the “Darnley urn” to distinguish it from other, less celebrated urns that have surfaced over the years.

The Darnley urn was kept in the Long Room at Lord’s until 1953, when it was moved to the MCC Museum at the same ground. Its prominence has led many to assume that the test series is named for it alone, and they believe it to be the trophy.  The Ashes, however, are metaphorical. It is an idea created by The Sporting Times, and one which grew in stature as it collected more stories. The Darnley urn is just one of those stories.

No doubt there are those who would read this and say, “so what?” Despite the history, they would claim that the Darnley urn has come to represent the Ashes for most people and should therefore be considered a trophy. I do not agree.

The urn is delicate and belongs in a museum so that it can be correctly maintained. The MCC respected the wishes of the Australian public and created a large replica trophy of Waterford Crystal to award to victorious teams. If we must have a trophy, this is more suitable than a 125-year-old terracotta artefact.

I don’t understand the attraction to trophies. I believe that the idea is more compelling than a trophy could ever be. The death of English cricket! What a notion! Since 1882 we’ve been playing tests to either regain England’s honour, or to rub her nose in it some more (depending on whose side you’re on). How simply marvellous. I doubt I’ll convince many of my fellow Australians to come around to my way of thinking; we’re too fixated on the physical, on ownership, on possession. If people know the history, though, we can debate these last points alone.

By Schedule 6, Part 2 of the Copyright Amendment Act 2006, “Reproducing copyright material in different format for private use”, the following activities are allowed:

• “Recording broadcasts for replaying at more convenient time” (such as taping the footy)
• “Reproducing works in books, newspapers and periodical publications in different form for private use” (such as photocopying an article)
• “Reproducing photograph in different format for private use” (scanning a hard-copy photo or printing out a digital photo)
• “Copying sound recordings for private and domestic use” (ripping a CD onto an iPod)
• “Copying cinematograph film in different format for private use” (coping a film from a VHS tape onto a DVD)

There is a glaring omission here – films on DVD and BD (blu-ray disc) are not mentioned. It’s still illegal to copy a film from a commercial DVD to another format or to another disc, even solely for your own use. If you have a portable video player (like an iPod or an iPhone) it’s illegal for you to rip films onto it. You are legally bound to watch the film through a DVD player.

Parents with young children might think to create a backup of their Spongebob Squarepants DVD, hiding the purchased copy safely out of the way lest their kids accidentally scratch or snap it. Some people may own home theatre PCs, and would like to copy their DVDs to its hard drive, allowing them to browse and play their entire collection from one location. Unfortunately, these are both illegal. When we buy a film on DVD we buy the right to watch it only via that DVD.

The law obviously recognises the value of format-shifting. It understands that there ought to be exceptions to copyright – for reasons of convenience, practicality, or protection of works – as long as it doesn’t hurt the copyright holder. It acknowledges that private use does not adversely affect the copyright holder’s capacity to make a buck (as might be the case if you were to sell bootleg copies). The law therefore allows us to put songs on our iPods, and I can’t see why it should be any different with DVDs or BDs. Surely the same principle should apply?

Perhaps it has something to do with the support that Apple’s iTunes enjoys from numerous music labels, and the lack of an equivalent service for films. One suspects that we wouldn’t have been allowed to rip CDs, either, if not for the existence of iPods.

It’s certainly not an oversight, because the Act drives the point home. DVDs and BDs often include some kind of digital rights management (DRM), to prevent us from copying our own discs. In Schedule 6, Part 2, Subdivision F of the Copyright Amendment Act 2006, “removing or altering electronic rights management information” is listed as in indictable offence (unless you have the permission of the copyright holder). Not only do the film studios block people from copying their films for private use, the Act gives their DRM mechanisms legal protection.

The difference between the private use rights of CDs and DVDs is inexplicable. My conclusion is that copyright law (or parts of it) is dictated by the big players in the film and music industries. In the words of a friend, “the people with the money and intent write the laws.” This is an unfortunate situation. Copyright exists to protect innovation, not to ensure that media conglomerates can sell the same person the same work again and again and again.

A reasonable person would have no moral or ethical problem with format-shifting media they’ve already bought. The Act itself acknowledges this by the way it treats CDs. That the same principle hasn’t been applied to other forms of optical media is disgraceful, as it suggests that film studios had their hands in the legislation.

Unfortunately, the update could only be applied to functioning drives. Seagate will apply the fix to bricked drives for free, but I was reluctant to send my drive to them because I didn’t want to give strangers access to my personal information. I wanted to do it myself.

After a bit of a search I came across this enormous thread. The first post has changed quite a bit since I first saw it – it initially contained a lot of true and false information, and the same followed in the rest of the thread. I spent some time cross-referencing the various opinions and experiences, and finally managed to unbrick my drive.

I had intended to provide a how-to here but I have since discovered that someone has already done it. What I did was pretty much the same as the author of that guide, except that I used a USB cable instead of a serial adapter.

I found myself a Nokia data cable (DKU-5) and cut off the phone end. With the help of a multimeter I determined which wires were used for transmit, receive and ground, and connected them to some wires I cut off an internal CD-ROM cable. These wires were attached to jumper pins, which I was able to slot into the hard disk. The USB end plugged into my computer, and I was able to connect to my hard disk via putty.

Apart from that, the steps I followed are identical to the guide above. I don’t recommend that people do it – if you have this problem and aren’t wearing a tinfoil hat, send it back to Seagate to safely recover your data.

Here are a few photos that I took during the operation.
