Git: prune those old branches

TortoiseGit’s right-click sometimes appears to freeze.

It can be caused by too many old branches hanging around.

Here’s how to prune the ones that have been merged:

git branch --merged master |grep -v master | xargs git branch -d

Thanks to my colleague UA for finding that one.

TortoiseGit claims commit message is empty

I was wondering why TortoiseGit* was complaining that my commits had no message in them.

“Aborting commit due to empty commit message.”

Turns out the new version by default strips out messages starting with a # character.

As detailed in this issue report, the over-ride is in Settings / Dialogs 2.

TortoiseGit options

*yeah, I’m not a hardcore Git user, though I do prefer Git Bash on Windows for some operations

Streaming TV and Chromecast – Stan won’t support iPad HDMI

I was in contact with Stan (streaming TV) support over the weekend. The iPad wouldn’t play, whether connected via an HDMI cable or the Chromecast. It would play zero to a few frames, then freeze up.

They suggested doing a factory reset on the Chromecast and removing and re-installing the Stan app.

It sounded unlikely (it’s the real-life version of the IT Crowd’s “Have you tried turning it off then on again”), but to my surprise, it actually worked.

HDMI was still a problem though. They said it wasn’t supported.

So why doesn’t Stan support HDMI? An interesting answer came back:

“We are unlikely to support this method of streaming in the future due to DRM (Digital Rights Management) contractual agreements we have with the studios we licence our content off of. If anything changes, we will be sure to let you know.”

This is puzzling, given their main competitors Netflix and Presto seem to support it.

It’s worth noting that Stan (and I believe the others) don’t support my 2011-model Samsung smart TV either. Thank goodness for the Chromecast. It’s not as easy as being able to play directly just on the TV (with no other devices required), but at least it works — and navigating menus is far easier on a tablet than a TV remote control.

As one observer (I forget who) noted — there’s little point paying extra for a smart TV (over a dumb one) when an A$49 device like a Chromecast is less likely to become obsolete — or if it does, it can be cheaply and easily replaced.

Enable Stereo Mix on Windows 7 under BootCamp

After rebuilding my Mac Pro with Windows 7 on an SSD (more about this later), Stereo Mix went missing.

To re-enable it, I ended up changing the audio driver to the Microsoft High-Definition Audio drivers, then back to the Realtek drivers:

  • Control Panel / Device Manager
  • Browse to Sound Video and Game Controllers
  • Choose Realtek High Definition Audio / Change (you’ll need an admin password at this point)
  • Update driver / Browse / Let me pick, and choose High Definition Audio Device.
  • Let it finish, then go back in again but at the last step choose Realtek High Definition Audio. This time I found it needed a reboot.

I assume this updates you to the drivers that came with Windows, rather than those that came with Boot Camp.

After the reboot, Stereo Mix is available. You just need to enable it under Control Panel / Sound / Recording devices, right-click, Show disabled devices, then enable it. You can set it as the default so you can record things in Audacity etc.

Comment spammers try to get clever

On my personal blog, on a post about the Melbourne public transport smartcard Myki, this comment popped into the moderation queue:

I found another very uefsul behaviour this morning.I don’t touch off when I get home at night. While, this seems weird how do they know I got off in Zone 1 (for which I have a pass) and didn’t travel into Zone 2 (for which I should be charged Money)? But, the fare manual says that if you have a MyKi Pass and you touch on in a zone for which that pass is valid (Parliament in my case) then there is no default fair.So, every morning when I touch on, it tells me deducting fare for previous trip . Which is $0.00. Cool.This morning I forgot to touch on some power issues on our line, got to chatting with the Station Hosts, just forgot. When I got to Parliament, I fully expected the gates to deny me egress and I’d have to do the silly thing where you act exasperated and they just wave you through the end gate even though you’re holding nothing but a wallet in your hand (MyKi works while in the wallet).BUT, it let me through. Seems that it’s happy enough that I started a trip (at Parliament) last night, spent 16 hours travelling and ended my trip back where I started. So it let me out basically a touch off of the trip home last night.Bizarre. But uefsul.

At first glance, it looked on-topic. But I was suspicious because the user link was to facebook.com/profile.php?id=XYZ (I’ve removed the ID) — and it came in the middle of a bunch of other (less-relevant) comments linking to similar URLs.

Googling around for key words in the comment, I found that it’s a copy of a comment from a completely different blog, with various misspellings inserted, and paragraph breaks removed. The original:

Bizarre. But useful.

It seems the spammers are trying to get a bit more clever at sneaking their comment posts past moderators.

I still don’t know why, given WordPress has used NoFollow on their comment links for about ten years now.

Spam from Cotap

Subject line: “You’ve been added as a contact on Cotap”

Email text: “Cotap is a secure texting app for teams. View the [company name] directory. [link]

“Are you using WhatsApp, GroupMe, or iMessage to text your coworkers? See why Cotap is better for work.”

Yeah, no, this is spam, and it sounds like quite a few people are getting them.

Cotap was formed by former Yammer people… there’s speculation that when they left Yammer, they took a copy of the Yammer email list with them.

In any case, don’t fall for their trap. Don’t do business with spammers.

In fact, why on earth would you trust your business messaging to spammers?

Panasonic DMR-PWT520 disc tray won’t open/eject

This model seems to have an issue whereby the disc tray won’t open, even if the front panel flap is correctly open. You press the Open button and nothing happens, though on the screen it’ll say Open.

Some recommend putting it into Standby mode (off) then holding down Stop and Channel Up. That didn’t work for me.

Putting it in Standby and holding down Open did work… it first started up, then after about 10 seconds, the disc tray opened.

(Possibly it needs a firmware upgrade… I’ll check that out eventually, though it’s not my unit.)

Was this answer helpful?

Go looking for any help on LinkenIn, and you get lies and incompetent software construction:

Linkedin needs JavaScript to enable JavaScript

Javascript must be enabled to use the Help Center

We’re sorry, but your current browser settings won’t allow you to use the Help Center. You can learn how to enable your JavaScript settings.

Notice the little UTF-square? If JavaScript’s turned on, that becomes a graphic image. Because, without Javascript HTML can’t include images, right? Not only that, once JavaScript is enabled the message with the graphic isn’t visible!

It then explains how to enable JavaScript, in the help centre that won’t help you without JavaScript – which is clearly a crock of shit. If the help centre can help me to enable JavaScript, surely it can help me with other problems also without needing JavaScript? Why lie like this? Why not say “our business model doesn’t work without you using JavaScript”?

To rub further salt into the wound, at the bottom is a “Was this answer helpful?” question, which you can’t answer because the buttons don’t do anything without JavaScript. Egads!

Flickr’s new HTML code embedding – how to remove the header and footer

Flickr has altered its default embed HTML to include a header and footer, which includes Flickr branding and the title of the picture.

PT in the Sense8 titles 01

Sometimes I suppose this is okay, but sometimes I just want the picture.

Fortunately it seems to be relatively easy to get rid of. In the example above:

<a data-flickr-embed="true" data-header="true" data-footer="true" href="https://www.flickr.com/photos/danielbowen/19038778583/in/dateposted/" title="PT in the Sense8 titles 01"><img src="https://farm1.staticflickr.com/313/19038778583_3149e7e01a.jpg" width="500" height="282" alt="PT in the Sense8 titles 01"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

…remove the data-flickr-embed, data-header, and data-footer attributes of the a href, and remove the script tags, like this:

<a href="https://www.flickr.com/photos/danielbowen/19038778583/in/dateposted/" title="PT in the Sense8 titles 01"><img src="https://farm1.staticflickr.com/313/19038778583_3149e7e01a.jpg" width="500" height="282" alt="PT in the Sense8 titles 01"></a>

The result should be just the photo, with the usual linking back to Flickr.

PT in the Sense8 titles 01

It’d be nice if they made this a built-in option when generating the HTML code.

Of course, it also makes me ponder if I should be finding another photo host.

Update 2015-07-20: They seem to have modified their default embedding code a bit so the branding and picture details now only appear over the photo when you mouse over it. Not so objectionable.

PT in the Sense8 titles 01

Flickr’s modified code now excludes data-header="true" data-footer="true" which presumably added the header and footer.

Turn off Twitter’s autoplay videos

I don’t know how much bandwidth Twitter’s new autoplay videos are burning up, but fortunately it can be turned off.
