Sometimes it happens that Xcode throws you an exception, and you don’t know why. How do you print the relevant Exception information?
To get more information, you can configure the debugger to break when any exception is thrown. Go to the Breakpoint Navigator and click the little ‘+’-button at the bottom. Then click “Add Exception Breakpoint”.
But, in many cases, even then you don’t get the information you wanted when the Exception occurs. Add these commands to the breakpoint configuration to show the name and reason of the breakpoint. This should get you on the way to eliminate the error.
po [*(id *)($esp+4) name] and
po [*(id *)($esp+4) reason]
This works when you are using LLDB by printing the name and reason of the exception in the command window. You can also execute those commands in the command window, but you have to make sure to select stackframe 0 first.
If you are visiting here from Stackoverflow.com, welcome. Today some Moderator at StackOverflow decided to remove 4 or 5 of my answers, because they all contained a link to my blog.
May I promote products or websites I am affiliated with here?
Be careful, because the community frowns on overt self-promotion and tends to vote it down and flag it as spam. Post good, relevant answers, and if some (but not all) happen to be about your product or website, so be it. However, you must disclose your affiliation in your answers.
If a huge percentage of your posts include a mention of your product or website, you’re probably here for the wrong reasons. Our advertising rates are quite reasonable; contact our ad sales team for details. We also offer free community promotion ads for open source projects and non-profit organizations.
Indeed in the FAQ it says that that is not allowed. However my answers were tailored to the questions and were in each case a correct and useful answer. The link to my blog is because I don’t want to repeat myself, plus you cannot post screenshots easily in StackOverflow. If I spend 4 hours to write a detailed tutorial with lots of screenshots, that answers relevant SO questions, I don’t see a reason why it is not allowed to link to it. My code is open source under MIT license. I don’t have a lot of advertisement on my blog. Hell, google adsense hasn’t paid out for more than two years now. I don’t even sell anything.
So in the future, I’m no longer posting to SO myself. If you find a relevant question on SO that one of my blogposts answers, you may ofcourse link to them.
I finally took the time to put the plugin I wrote in the wordpress plugin repository. This makes it even easier to set it up on your Blog.
Simply go to the administration area of your blog, go to the Plugins section and click Add New. There you search for “Full screen background” and normally the first hit should be my plugin.
The next step is to activate it, and change the image you want to show. You do this by editing one line in the source of the plugin. You can do this by clicking the Edit link next to the plugin in the list of active plugins. The line you have to change is indicated with a html comment. Change the src attribute of the img element. That’s it.
Please provide feedback if it works or doesn’t work for you. Thanks!
A while ago, I wrote about my VLAN setup for the Telenet local network.
Today, Bert, the Telenet technician came in for a modem-swap, and activated Fibernet40 on my subscription. It is the same price as the older “Gold-Shake” that we had, but you get a lot more bang for your buck: 100GB limit instead of 60GB and 40Mbps instead of 10Mbps download speed. (and some other extra’s)
Another advantage is that now they installed a Modem with integrated Wireless router and wired switch. So my old-setup is now obsolete. This is the new topology:
So it eliminated the use of an extra router in my home, it is actually built into the modem itself. It supports 802.11N, so it is way faster than the one I had. The speed is really great!
In my home, I’m using 200Mbps Powerline Ethernet boxes to transmit the signal without the need for other cables. I have a switch under the tv, to get network to my XBox, I have another switch in the other corner of the room to get the network to my printer and PC. The laptops use wifi (duh) at equal speed as the wired network.
I don’t really understand yet how Telenet actually achieves this setup, because devices behind the modem get an internal IP, in the 198.168.0.* range, while the digicorder still gets an IP in the 10.166.179.* range. I should sniff my local network to really know what is going on. I will do that if I have a little bit more time. For the moment I’m just enjoying the Internet in high speed.
Note that the managment UI for the modem is reached through mijn.telenet.be, which is kind of nice. This means that they can remotely manage my modem/router. I don’t really mind doing that myself, but it’s nice to know they can help less knowledgeable users.
So don’t sit around, pick up the phone and make an appointment with Telenet today, to upgrade your internet experience for free. I didn’t have to pay activation or installation costs at all!
