Running multiple instances of Chrome on Mac/Linux

Sometimes it’s handy to be able to have multiple browser instances open at once. For instance, Google’s Multiple Login only allows me to have 3 accounts signed in at once, which isn’t enough for me to have all the personal accounts I want to check plus my work account. Even if it could, I like to keep my personal and work search and browsing histories separate, so that it’s easier for me to find something I vaguely remember seeing recently.

When doing web development, it’s often handy to have one browser signed into the site as an admin, another signed in as a regular user, and one not signed in. Chrome’s “Incognito Window” feature can help with one of these, but you can’t have two Incognito windows at the same time (at least, not on Mac/Linux – I hear tell that the Windows version may have supported multiple incognito sessions at some point, but I don’t know if that’s still the case)

So.

I’ve created a little script. I call it chrome and it lives in ~/bin on all my machines. It detects the platform and calls the appropriate binary.

More importantly, it takes one (optional) parameter, which it uses to figure out which profile to run.

I usually start my day by running this script twice: once as chrome work and once as chrome personal. The order is significant, as clicking on urls in other applications will result in them being opened in the first profile that ran. So, while I’m at work I want most things to open in the work profile; if I’m not working I want a different default behaviour.

If you don’t pass a parameter, the script will invoke the default profile – the one that gets used if you don’t specify a profile at all.

I’ve put the script on github for your amusement and pleasure (and hardcore forking action).

Free voicemail transcription on Telstra Prepaid (and postpaid too!)

In the last few months of being with Optus, I trialled a service they offer which transcribes voicemails to text and sends and SMS. I loved this feature – even when it’s not entirely accurate, the transcription is enough that I can figure out who the message is from, what it’s about, and how urgent it is that I call back. In a lot of cases it’s just someone passing on some information and there’s no need to call back at all.

When I ported my first mobile service to Telstra prepaid, I was delighted to find that I was getting this service for free. I had seen Voice2Text mentioned on Telstra’s site and assumed that this was the service I was getting.

A few weeks later I ported my second service to Telstra prepaid – but on this service, regular voicemail was in effect. I sent Telstra’s Twitter team a message asking how to activate this:

I have voice2text on my first prepaid account (0407123456); I’d like it on my second prepaid phone (0403654321) as well.

Unfortunately the team were only able to tell me that Voice2Text wasn’t active on my first service, and they guessed that ‘It may only be available for Post-Paid accounts‘. They suggested I call the standard support number just in case they were wrong.

All of this was a shock coming from Optus, where the team who run the @Optus account are knowledgeable about their product range and proactive about solving problems – their response would have been to call me and ask for more information to find out what I was actually seeing on my phone; they never wasted my time with guesses about what services might be offered, they would make sure they had all the information to hand before they called me – and they would never tell me that a service I’m receiving doesn’t exist.

(disclaimer: I worked at Optus 3ish years ago, my old team worked some of the backed that the @Optus team use – but as far as I know this had no bearing on the service I received from the team. Please don’t confuse my love of the @Optus team with an endorsement for the company overall – I had terrible coverage issues which they were unable/unwilling to address, which is why I’m now a bitter ex-customer of theirs. It’s a shame that such quality customer service couldn’t be backed by a network that has a semblance of coverage and the ability to make and receive the occasional phone call. But I digress…)

Today, a friend pointed me at a different Telstra service called variously ‘Call Back Notification’ or ‘Message2Text’. This service offers people leaving me a voicemail ‘the option to leave a short 10 second message that is converted to text and sent to you as an SMS‘. Sound familiar? This is identical to Voice2Text – except for the 10-second time limit, and the fact that it’s completely free and available even on prepaid.

To activate this, you need to disable the Messagebank service on your account. The Telstra site says that thai requires a call to their call center; but I can confirm that dialing ##002# turned off MessageBank (and thus turned on Message2Text) for me. I’m not entirely sure how to turn MessageBank back on – but as I don’t intend to use it, I don’t care.

Your iPhone will be happier on Telstra Prepaid

Update: It turns out that the $49 for 2Gb was way too much – my actual usage is less than 700Mb a month.

Instead of the complicated shenanigans below, I now just add $40 of credit once a month, and convert $39 that to 750Mb of data. This means I’m paying just over $480/year, down from $708 on Optus.

—–

I’ve recently switched my iPhone from an Optus post-paid plan to Telstra prepaid. The primary motivation for the switch was coverage – I work only 500m from my home, and Optus coverage in the area ranges from poor to non-existent – but it turns out that Telstra’s pre-paid plans are better value (for my needs) than Optus’ post-paid contracts anyway.

On Optus, I was paying $59/month every month. This gave me 500Mb of data, of which I used around 300Mb/month on average. I was also making around 80 minutes of calls per month and sending around 120 SMS/MMS – I could have used around 4 times as much without exceeding my cap. In short, Optus were giving me lots of unneeded credit to spend on calls/SMS/MMS, but not as much data as I would have liked.

By contrast, I’m now paying $12.50/week to Telstra for a service that has ridiculous amounts of calls and SMS – even more than then the ridiculously high Optus cap, which I never managed to get close to using. Importantly, it also has 4 times as much data as the Optus plan did – and even better, the coverage and network quality is so much better than on Optus that there’s some chance I might use a good chunk of that data!

Telstra’s pre-paid service options are broad though, and it took me a while to figure out exactly what I wanted (even after I had help from workmates who’d made the same transition earlier). Largely this is because adding data onto the account is a separate step from recharging the rest of the account – but also it’s not clear when various things expire. This post is my attempt at making it easier for other people to negotiate the maze of Telstra’s prepaid options.

In order to end up with this, I have to:

  1. Apply a $60 recharge to one of the prepaid plans – specifically, I choose the “Talk & Text+” plan as it’s the closest match to my needs. After applying the recharges, this gives me 300 minutes of calls and 600 SMS to use – as well as $60 credit. This credit can be used once I’d run out of free things – or it can be used for things that aren’t covered by the free calls, such as calling Telstra’s prepaid service number (Yes, that’s right: when I was activating my iPad sim, Telstra charged me $0.25 for the privilege of having them set up another source of income for them – calling Telstra for help from a Telstra service is not a free call)
  2. Yes, I know I said I was paying $50/month and I’ve just started by paying $60 all at once.
  3. So at this point, I have $60 of credit, and I have insane amounts of free calls/sms, but I don’t have any data to use. To get the data, I have to buy a PlusPack – paying for it out of that $60 credit currently in the account. In my case, I choose the $49 pack, which gives 2Gb of data.
  4. At this point, I have: 300 minutes of calls, 600 SMS, 2Gb of data, and an extra $11 credit sitting on my account. All four balances expire in 30 days time. I’ve paid $1 more than I would have paid on Optus

28 days later, those balances are about to expire, so I go through much the same process:

  1. Pay $60 to add $60 credit to the account. This extends the life of the previous $11 so that it expires on the same day as the new $60 – so I have a total of $71, expiring in 30 days.
  2. Because I’ve chose the “Talk and Text+” plan, this adds another 300 minutes and 600 sms to those balances – and as with the main credit balance, the life of the existing credits gets bumped to the new expiry date, 30 days from today.
  3. Convert another $49 of credit into another 2Gb data pack. This does *not* extend the life of the previous data pack. However, the new data pack won’t be touched just yet, as you still have an existing pack active – you need to exhaust the old pack first. If you’re dedicated to getting the best possible value from Telstra you could do your best to suck up the rest of the 2Gb by the time the data pack expires – or you could just let it expire at the end of the day.
  4. At this point, you have 600 minutes (minus whatever you used during the month – so in my case, around 500 minutes) and 1200 SMS (minus whatever you used during the month – again, in my case, that’s about 1100 left), 2Gb of data (plus whatever is left in last month’s data pack – after my first month, that was a tad over a Gb left), and $22 of credit – all expiring 30 days from today.

28 days later, it’s time to renew again – but this time, only a $30 recharge is needed. Added to the existing $22, that’s still $3 more than is needed to top everything up by the usual amounts. This only adds an extra 100 minutes of calls and 200 SMS to the balance – but that’s going to leave me with around 400 minutes of unused talk time and 1100 SMSes at the end of the 28 days

28 days after that, I’ll have spent $150 in 12 weeks (compared with $177 I would have spent on Optus in the same period); I’m left with a large balance of free minutes/SMSes in case my usage ever increases (on the Optus plan, any of the freebies you didn’t use within the month just vanished), and if I try hard I might have used at least half of the data provided. After a full year, I’ll have paid $637 to Telstra, instead of $708 to Optus. If you recharge every 30 days instead, that would be just $600 (and a tidgy bit more for the extra 5 days).

Sheesh. 900+ words to explain the gymnastics I have to go through in order to save $100/year? If it wasn’t for the fact that this also gives me access to a mobile phone network that actually works, it wouldn’t be worth it!

PS: I believe my $59 plan was an older version; I believe the current plans give you 700Mb of data for the same price. Optus never bothered to suggest I move onto the better-value plan – and as far as I know the only way to do that would have been to sign another 12 month contract, which I wouldn’t be willing to do until they can provide coverage around the area where I live/work. Even so, more data (750Mb) can be had for just $39/month on Telstra prepaid – much better value.
