VirtualBox 4.3.22

VirtualBox 4.3.22 arrived yesterday, and here was me thinking it was dead. :)

The downloads and changelog are in the usual places.

Happy upgrading!

Oracle, please take my money!

I need to renew my Oracle Support contract. Everyone on the intertubes tells me Oracle are a money grabbing evil empire right? So it follows that they are going to be really on the case with a support renewal right?

Two days ago I wrote an email to customer services to try to renew my support contract. Since then I’ve been bounced between 5 people and I’ve still not managed to pay any money. It surely can’t be this hard!

This has all come about because the Oracle store doesn’t allow me to alter my credit card details, so the auto renewal failed. This feels like a, “Do you even internet?”, moment…

MacBook Prod 15″ Retina : Mini DisplayPort to VGA Adapter

I mentioned in my recent post about Riga Dev Day 2015 I had some trouble with my VGA adapter and had to borrow one from Andrejs. It seemed to be working fine before I left. I was going to buy a cheap replacement from Amazon, but after reading a few reviews I bought another £25 adapter from Apple. Both the new one and the old one seem to be working fine…

The Apple website says the “Mini DisplayPort to VGA Adapter” will work with either a Mini DisplayPort, like I had on my old 13” MBP, or a thunderbolt connector, like I have on the new MBP.

I did a bit of hunting on the net and it seems there are a lot of people out there having trouble with the retina MBPs when connecting to some projectors. Currently I have the native HDMI connector, which I’m using to connect to a second monitor. I also have 2 VGA adapters and a DVI adapter. I feel like that should cover all the bases, but I still feel like I should be taking my old laptop with me, just in case…

If anyone else out there has a recent 15″ MBP Retina with only thunderbolt connectors, I would be interested to hear your experiences with projectors on your travels. Should I be worried? :)

Writing a new conference presentation

At the weekend I put together two new talks. One is a session for a local University, which I will blog about when it is confirmed. The other is a new conference presentation called “Pluggable Databases : What they will break and why you should use them anyway!”, which I will be presenting at Oracle Midlands Event #8 and OUG Ireland 2015.

I find the process of putting together a new conference presentation quite daunting. I have an abundance of material to draw from, but the difficult thing is deciding on a specific message and finding the best way to deliver it with a suitable amount of impact. I don’t know how other people approach it, but I usually do something like this…

  1. Write down bullet points and just talk about them out loud, trying to get a feel for what I can say about them. Almost like I’m in a conversation with someone about it.
  2. From that stream of conciousness, I try to pull out the points that I think others will care about.
  3. Put some slides together with some relevant information on them. If there are demos, sort those out too.
  4. Run through the talk several times as if I were doing it for real.

At that point, I feel like I’m in a position to make a judgement about how I think it is working out. Sometimes you have to throw it away and start again. Sometimes you realise your emphasis is off target and you need to adjust your focus somewhat. Sometimes you don’t notice this until you are in front of a real crowd, as described here.

So for the next few weeks I have the mildly mind-numbing task of running through this stuff and “polishing” it, so hopefully it will be alright on the day.

Raising Steam

Raising Steam is the 40th book in the Discworld series by Terry Pratchett.

I waited a long time before starting this book because I heard from several sources that it wasn’t very good and I didn’t want to ruin what has been an awesome 39 book series. I finally bit the bullet and I’m really glad I did because I really enjoyed it. Maybe some literary types can argue some difference between the earlier books and this one, but as far as I can see it’s the same Discworld stuff I’ve enjoyed all along.

Steam trains have come to Discword and most of the world has fallen under their spell. I used to love toy trains as a kid, so I could relate to this. :)

phpBB 3.1.3

I just noticed that phpBB 3.1.3 was released at the start of the month.

Although the forum is still locked on my site, it pays to keep things up to date. :)

Happy upgrading.

Statistics Collection Enhancements on Oracle Database 12c

I’ve been having a play around with the enhancements to the statistics collection in 12c. I’ve put together this top-level post with links to all my other articles on this subject.

Here are the new articles it links to.

It also links to some of the stuff I put out previously for the Adaptive Query Optimization functionality, as that is statistics related.

In a totally unrelated incident, I wrote this thing about the new READ object privilege, but forgot to mention it on the blog.

The journey continues…

Keyboard Warriors : Unite and do something positive with your lives

I follow a few non-Oracle channels on Youtube and I sometimes check out the comments, which seem to be a constant stream of keyboard warriors posting their negative rubbish. Whatever people do, the commenters claim to be able to do it better, or claim they know someone who can. If it is sport or fitness related, it will be followed by accusations of using performance enhancing drugs, which although it may be true, does not negate the thousands of hours of training and dieting people put in to get where they are.

The technology press makes your average Youtube channel comments section seem like a playground spat. Lots of articles by people who are totally ignorant about the technology they are “reporting”. In many cases, spending 5 minutes reading Wikipedia would be enough to dispel most of the garbage that is written, but unfortunately, those with an axe to grind don’t even do that. They read a headline and run with it. The language is straight out of conspiracy theory. Phrases like, “some experts believe”, and, “an insider told us”, are used like they are going out of fashion.

Imagine a world where all the time spent writing derogatory comments and downright lies was spent on doing something productive. Maybe producing informative articles and videos to help people, or contributing to open source projects. The press and TV has long been fuelled by fear and hate. Social media is one giant hate crime. If people aren’t being directly mean, they are trying to convince you that their life is better than yours, or their children are prettier or more intelligent that yours. It is all so terribly sad and boring. I’m not claiming I am above all this. I have been guilty of the same thing on numerous occasions.

So next time you do *anything* ask yourself, “Will what I am about to do have a positive impact?” If the answer is no, you probably shouldn’t do it.

Surprisingly, this post was not initiated as a result of something that was said or done to me. I have just witnessed several things this week that have made me really angry. What really irks me is I allowed those people to have that power over me. I allowed their actions to make me angry.

Enough of this hippy bullshit. I’m going to play with 12c…

Fedora 21 : Upgrading from Fedora 20

I just did an upgrade of my old desktop from Fedora 20 to Fedora 21. The process was similar to this old blog post, but there were some variations, so I’ll list the procedure here.

  • Update your current Fedora 20 system by issuing the “yum update -y” command and restart once it is complete.
  • Install the latest “fedup” package using “sudo yum –enablerepo=updates-testing install fedup”
  • Run the “sudo fedup-cli –network 21 –product=nonproduct” command.
  • If you are using Dropbox, disable the repository using the “yum-config-manager –disable Dropbox” command. Re-enable it once the Fedora 21 repository is available.
  • Run the following clean up commands.
    sudo rpm --rebuilddb
    sudo yum distro-sync --setopt=deltarpm=0
    
    sudo yum install rpmconf
    sudo rpmconf -a
  • If you are using Chrome, uninstall and reinstall Chrome.

It seemed to go fine!

Cheers
