Pretty fast… for Australia

Yes I’m talking about 10 megabit Internet, of course. Which I now have – w00t. But I almost didn’t.

Got to the new place and hooked up my Billion 7404VGO-M on Internode ADSL2+ NakedExtreme plan. Only got 6 megabits per second! Removed all devices (isolation test), including my line filter/splitter – it’s Naked no need. Got minor speed improvements, but still around 6 mbps. Rang up Internode and found out about their “ADSL2+ Profiles” which you can change via web site. I was on the “Very High Reliability” profile. Switched to “High Speed” and now have 10 mbps. Profile may affect stability buy I’m willing to try out to see what happens.

I am glad I found out about this feature! I was at a loss as to how I was going to improve my setup to get more speed. They even have a “Low Latency” profile for gamers who need low pings. I wonder if other ISPs like iiNet have this feature. Here is a picture.

How to fix AirTunes dropouts

A while ago I got an Airport Express to pump iTunes through my stereo and had a few problems setting it up. Rather than use it as an access point, I wanted it to act as a node on my existing wireless network. It supports this but I experienced frequent audio dropouts when using AirTunes this way. Forums suggested changing channels, unplugging cordless phones, moving access points etc. etc. and I tried all of them, and all to no avail.

The solution? Well I believe the problem stems from AirTunes using A LOT of bandwidth; 160 kB/s in my experience. I suspect this is flooding the wireless network as it has to go in 2 “directions”, i.e. from the MacBook to the router, then from the router to the Airport Express. So the solution I found was to disable the Airport Express wireless altogether and plug into my router using the ethernet cable. This eliminates one of the “directions” and so alleviates the flooding. The only problem others may see with this solution is that you need to move your broadband router next to the stereo. This isn’t a problem for me as it’s already there for the Xbox 360.

Now I can use my Airport Express for what it was intended, and it totally kicks arse. It’s just a shame Apple didn’t spend the time to test thoroughly in node mode.

My Macbook Pro battery died

First it would get down to 10-20% capacity then the Mac would suddenly shut down.

Then eventually it stopped charging all together. I tried resetting the SMC. After this, the battery charged once but when it discharged, would not charge again.

So I bought a new battery for $140 on eBay. I calibrated it straight away.

  1. Charge to full
  2. Wait 2 hours
  3. Drain to empty
  4. Wait 5 hours
  5. Charge to full

It’s working fine now. Does anyone need a shiny aluminium paper weight?

Firefox 3 causes Mac insomnia

If I leave Firefox open on my MBP, it refuses to go to sleep. Now this bug report claims it only delays sleep, but that’s complete bollocks. I’ve left it on all night with Firefox open (no windows) and come back in the morning to find my poor little Mac has been lying awake at night in distress! Aaargh! If any other Mac users are experiencing this, I feel your pain.

Toast Roxios my socks off

Burning Toppy shows to DVD just got a WHOLE lot easier. And faster.

What I used to do:

  1. Copy .rec file from Toppy
  2. Demultiplex .rec with MPEG Streamclip into separate video and audio streams (.m2v and .m1a)
  3. Rename .m1a to .mpa so the next step would work
  4. Remultiplex these 2 files to DVD (VIDEO_TS) format using ffmpegX
  5. Burn with Roxio Toast

In what is simply a revelation, I just figured out that Roxio Toast can burn demultiplexed video files. O. M. G.

What I do now:

  1. Copy .rec file from Toppy
  2. Demultiplex with MPEG Streamclip
  3. Burn with Roxio Toast

Before it was an utter chore to the point where I just didn’t bother. Now, I can simply drag the .m2v file into Roxio and if there’s a .m1a or .mpa file sitting there with the same name it just figures it out and remuxes both streams as part of the burn process! It also automatically adds chapter marks every 5 mins and this was something lacking in my previous burns. It’s also a lot easier to add multiple titles to a disc. And I could potentially add menus, something I’ve steered clear of until now because of the complexity involved.

I’m so impressed that I’m actually slightly embarrassed to admit that I used to do this in such an inefficient way.

And no, I don’t think a DVD recorder would be a better solution. Lets face it, I’m a bloody pedant when it comes to video trimming and ad-removal. The software solution allows frame precision. So it might take a little extra time but the end product is worth it. Plus I would miss my Toppy!

Optus Usage Alerts

If you have an iPhone with Optus and are trying to sign up to their Usage Alerts thingy through the website, you will get this error:

The service you have selected is on a mobile plan or fixed line service that does not support Usage Alerts.

I just spoke to a guy at Optus who was actually useful and actually knew what was going on and actually spoke English! What are the chances? He said the website is still being updated to include Usage Alerts functionality for the iPhone because it’s a new handset this hasn’t been done yet. Apparently the update is not so straightforward as the iPhone (allegedly) uses different technology for its data usage than regular phones. They don’t have an ETA of when Usage Alerts will be available to iPhone users. This could all be bullshit but it makes me feel better believing I will be able to get it one day.

If you’re on a Post-Paid mobile Cap Plan or have a fixed line account, it’s easy to control your spending. Just set up a Usage Alert and we’ll send you an SMS when you reach your chosen limit.

DO WANT.

More than just a games console

The Xbox 360 is a pretty neato games machine. Hovever, lately I’ve discovered that it simply excels as a media center. Why? It plays MPEG-4 videos of course! It required a minor software update which was straightforward once I got Xbox Live up and running. It plays videos from a burnt CD or DVD which is handy, but the real treat is its ability to play videos on mass storage devices connected via the USB port. Brilliant! It also connects to a Windows PC which is nice but a feature I’ll probably never use as my MPEG-4 stuff is on USB HDD or DVD. I have to hand it to Microsoft though, they’ve nailed it here. The Xbox 360 has already replaced my Macbook Pro as the primary device for watching MPEG-4. The icing on the cake is my Logitech Harmony 525 universal remote, whose software simply downloaded all the codes for the Xbox 360! Truly awesome.

GPS vehicle tracking – what’s the big deal?

I read an article in The Age about employees committing suicide then their family saying GPS trackers in work vehicles were a contributing factor.

Employers are fitting out their fleets of company cars with invasive GPS tracking systems despite claims the technology unnecessarily invades staff privacy and contributed to the suicide of a Telstra linesman last year.

What the?

I know there are companies putting trackers in their fleet vehicles. Some even do it without telling their employees, and that I have a problem with. But when the employees know a tracker is there, what’s the problem?

Personally, I wouldn’t have a problem with it. I have been wanting trackers in our work cars for ages. For one, it would mean an end to filling out that stupid log book. And to people forgetting to fill it out, and filling it out incorrectly, etc. And secondly, I know there are people that do abuse the resource, and this would put a stop to that.

The fuss seems to be about invasion of privacy and lack of employer’s trust for employees. But there need to be allowances for this resource to be used with flexibility. How flexible is the employer willing to be with their vehicles, and how they allow their employees to use them? The problems arise when you get draconian employers using minute details in the data in unfair ways.

An employer that respected their employees would develop some simple software to examine the data collected and find obvious patterns of abuse, then take appropriate action against the abusers. They would also clearly state their policies on vehicle use, and any thresholds that would constitute abuse. These policies would be developed in consultation with employee representatives, aiming towards a fair balance between flexibility and efficient use of company resources. For example, employees could be allowed to stop and pick up milk on the way home, etc.

Our company’s policy states that stops of less than 30 minutes during a journey do not need to be recorded in the log book. So an employer’s policies would need to reflect those they had before trackers were introduced. When employers learn to respect their employees and reflect this in their policies, devices like GPS trackers would not cause as much upset and may even be welcomed.

Update 16/8: Added quote from article.

Transmission multiple tracker support

In my opinion, one essential feature of a Bittorrent client is the ability to add multiple custom trackers to torrents. This is not only useful in getting more peers, which in most cases results in faster downloads. It also adds a level of redundancy, so should one tracker go down, the transfer keeps going.

I just noticed today that the Mac Bittorrent client Transmission now has this feature. Apparently it’s been there since v1.30 (I’m using v1.33). Tracker entry could be streamlined a bit though; at the moment, you need to add trackers one at a time. In uTorrent you can quickly paste several in one go. What would be really nice would be a global custom tracker list that was added to every torrent loaded into the program.

My iPhone 3G Experience

I’ve had it for a while but only now got around to writing this. Despite the negative points below its still by far the best phone I have ever owned and I love it to bits.

The OMG!!!

  1. Flush headphone jack and dramatically improved audio quality! Summed up: it’s actually an iPod now. I can easily say this is the one feature that sold me on the new phone. On the old iPhone every preset I wanted to use caused serious distortion even at low volume, making it utterly useless as an iPod.
  2. The new case. I continually rejoice at the curved all-plastic back. The plastic has a much higher friction coefficient than the old aluminium back. In other words, the new back is way more “grippy”. The old phone would slip and slide around in my hand, leaving me anxious about dropping it. The result of this was that I actually used the front glass to hang on to the phone. Not ideal when this is the main control interface. The curved edges are nice too, doing away with that scary sounding thud when placing your phone on the table. Now you get a brief wobble which sounds way better for the phone.
  3. Aurora Feint. Freakin awesome puzzle/RPG game. Totally addictive and very immersive animation/interface/music/sfx. And Free! Unfortunately, it’s a total memory hog, and menus can sometimes lag. In most cases it requires a phone reboot prior to play. But its all worth it.
  4. The App Store. What an excellent idea. Makes the phone a true “platform” swinging the doors wide open for some extremely creative software. A shame Apple is so restrictive about some of their apps. Google “rejected from app store“.

The Good

  1. I complained to Optus staff that I didn’t want to be sans-phone while my number was ported over to Optus. So they gave me my new SIM early so when the port occurred, I could just chuck the SIM into my interim phone. Oh yeah, and the closest store is 1.5 hrs drive so they posted my phone, which was nice. Still had to visit the store to sign up which was to be expected.
  2. No in-store activation! As a consequence of the first point, I managed to completely avoid the rumoured in-store activation. When my iPhone arrived, I just chucked in the SIM and activated it myself through iTunes. Interesting side-note: The store trainee was the one who suggested iPhones could be activated by users at home. She said “the only reason we activate in-store is so that customers can walk away with a working phone”.
  3. The country code bug is gone. I won’t say “fixed” because it could have been a quirk of Virgin’s service. The bug was that texts came from number format +61418555555 whereas calls show up as 0418555555. The phone saw these as separate numbers, so you had to have both numbers stored in a contact which is just annoying.

The Dissapointing

  1. My biggest disappointment is that most developers, including those at Apple refuse to acknowledge the device’s superior usability when turned sideways. Not only is typing remarkably more efficient with a bigger keyboard and nice fat buttons, but most non-keyboard apps are more comfortable to use, especially Safari which I use exclusively sideways. Apps I would like to see with sideways support include SMS, Mail (composing), Maps, and basically anything where you type.
  2. The App Store interface needs some work. I read in a blog about the lack of a shopping cart. This becomes a big deal when you are scrolling through a list of 500 apps, you install one and it exits App Store. You go back into App Store and its at the summary screen of the App you just installed. You go back to the list of apps and you’ve lost your place in the list. This forces users to remember their place in the list and this is a serious usability flaw. A shopping cart would eliminate this by removing the “exit after install pressed” behaviour. It would also be useful as you could browse the store over EDGE/3G and wait until you had WiFi to “checkout” as it were.
  3. YouTube is inexplicably slow at buffering videos even over WiFi. I load the same movie in Firefox and there are no underruns, but on the iPhone, videos take minutes to buffer (longer than the length of the video in some cases). This just makes you ditch the phone and walk over to your computer! YouTube also lacks a proper cache, meaning that if you’ve just watched a video a minute ago and want to watch it again, the whole movie is downloaded again. There is so enough room on the flash for even a small cache of 50MB or so.
  4. No MMS. I didn’t actually realise this until I was sent a text saying “You have recieved an MMS. Visit this website to view it” Lame Apple. Just LAME. This omission of a technology that has been present in phones for several years simply lets down something calling itself a next generation device.
  5. Lack of proper Gtalk app. There is Palringo but it’s bloatware. I just want a slim Gtalk app with push message support. Thanks in advance Google.
  6. No 3G Optus coverage. I’m stuck with GPRS up here. There is “3G” coverage, but on the 900MHz band which conveniently is not supported by the iPhone. Not such a big deal. I’m over it.
  7. Still no Flash. Perhaps we can blame Adobe and licensing restrictions etc. for this. But why the lack of flash, Apple? Please explain.
  8. Shazam. You hold your iPhone up to the radio or some other music source. The app picks the artist and track name. It works, but the probabilty that a track is correctly identified is directly proportional to the popularity of the song. Not something I’ll lose sleep over, but disappointing nonetheless.
  9. No Dock. Last in the list because I wouldn’t use it anyway. But I didn’t get a dock with my iPhone. Meh.

The Downright Bad

  1. The Ringtones. No excuses! These are some of the worst ringtones I have ever seen in the history of the universe. Seriously, I would have Crazy Frog before I would have some of the included ringtones. At least you can (relatively) easily make your own. This customisation doesn’t extend to other sfx, most importantly the SMS alert. I shouldn’t have to jailbreak my phone Apple. But your sounds are SO CRAP I’ll do it in a blink once a suitably stable hack emerges.
  2. No Visual Voicemail! WTF? Excuse me while I rewatch the Keynote and observe this as one of the key features of the iPhone. I smell a class-action lawsuit, I do. Unfortunately, I doubt the ACCC could do much as I suspect Apple were very careful not to advertise this feature in Australia.
  3. iTunes Account problem. You can only authorise 5 computers to download apps to the iPhone. If you want to waste one of those auth slots, here’s how. Sign in with iTunes account. Authorise that computer when it prompts you. Change your email address on iTunes account. Attempt to download apps to iPhone. Get prompted again to authorise this computer. Lose one of your auth slots. Voila!
  4. The Optus support voice recognition lady. OMG she is such an idiot! Why can’t these things just say “Press 1 for mobile phones”, “Press 2 for landline”? I want to know who on earth decided that voice recognition in this context is more usable than the old number menus. She is kinda fun to mess with though. I was so frustrated one day at work I started shouting at her. Her response induced at least 30 minutes of uncontrollable laughter. Me: “Suck my balls!” Response: “I’m having trouble with that”. I guess you had to be there…
