I’ve mentioned X-Plane before – it’s a flight simulator that strives to be as accurate flight modeling -wise as possible. Realism is one of their goals and it’s also unique in that it’s available for Mac/Windows and Linux (version 8 that is). (There is flightgear also, but X-Plane has still felt like better competition for Microsoft’s Flight Simulator line.) Anyway… Version 8 had linux support. Version 9 has beta’s out now for Windows and Mac, but there are rumors in the forums that version 9 may not see linux support. (Apparently the person in charge of the linux port has been hired by Google and was working on the linux port in his free time gratis…) I hope we’ll see a version 9 of X-Plane for linux. I wish I could lend help, but bash scripting is pretty much the zenith of my coding skills. (BTW – version 9 LOOKS nice from the screenshots I’ve seen. Here come a few more x-plane related thoughts….

Graphviz and dot
I’ve been puzzled a bit by the graphing output of gramps – it leaves me with a file with a .dot extension that I didn’t know quite what to do with. It opened in text editors as just markup, no image viewers I used seemed to like it, so I researched graphviz (as that is what is used to make the dot file…) and found that there are ways to get an image out of a dot file… (the easiest is a command-line $dot -Tsvg strangedotfile.dot>strangedotfile.svg ) which should give you a scalable vector image with the same information as the .dot output (of course you can use -Tpng to specify png as well.) (BTW, the default settings with gramps give you a single page maximum so things may be VERY scrunched to fit in.)

Boot up freeze/sluggishness with ubuntu 6.06.1 install cd (on 64bit AMD hardware)
I thought I had written about this once before, but when I searched the site to find the solution I had come across before, I couldn’t find my post…. so, sorry if this is a duplication, but I’ve run into this on some AMD 64-bit based system boards. The most recent was based on the nvidia nforce4 chipset. Essentially in booting from either the alternative install cd or livecd for Ubuntu/kubuntu/edubuntu/xubuntu…. there is a freeze in the boot process. It goes for 30 seconds or more looking as though it’s hard frozen, but it does eventually manage to load the installer.

Google Coupons and improving Picasa
There are a couple of stories on the “Google front” today. First up Coupons tied into Google location searching (maps.) More details at the Adwords blog. (BTW, this is open to US businesses, an Adwords account is not a requirement.) It looks like they’ll put up printable coupons for businesses. There seem to be quite a few possibilities for extending this idea. (More coverage here.) The next item puts to rest a rumor from some time back. It seems as though at one point in time, Google was interested in Riya, who specializes in image recognition (hey – that’s Bob in that picture.)

Targetting the OS is old hat….
The Register sums up the Black Hat briefings pretty well. The Operating System level has received a lot of scrutiny in recent years for security flaws and as a result there has been a good deal of improvement there and so now, researchers are heading to the low hanging fruit of the REST of the software stack, be it the drivers, or browsers, or office software. Another area of software were those class of programs that run checking for updates for OTHER software. It’s time to realize that most ANY piece of software could compromise system security and updates need to be expected for most any part of the “software stack”.

Converting MPG video to dv files
I don’t know much about the dv format, except that it is a standard format that many camcorders use. For this reason, many video editors (such as kino for linux) prefer to see files coming in dv format. The problem I ran into is that the new handycam dvd puts images in .VOB files (which are really MPG). So, I found this handy script… that runs on Mac or Linux and is called mpeg2dv. It does the trick and is public domain. The only requirement I can see is ffmpeg.

Fasten your seatbelts – Browser vulnerability a day to be announced in July
I hope there aren’t too many browser developers that have planned on taking July off….. I ran across browserfun.blogspot.com where it is planned to release information on a web browser vulnerability EACH DAY for the month of July. This comes to us from HD Moore of Metasploit. Judging from This securityfocus article, most of the vulnerabilities may just lead to a browser crash, but some seem to be remote code execution vulnerabilities. Microsoft Internet Explorer is where they found most of them, but other browsers were NOT immune and did find at least one remotely exploitable vulnerability to gain remote access for each browser tested.

VMPlayer on Mandriva 2006 finally…
As you might recall some time back I talked about the release of vmplayer which is a free virtual machine “player” from vmware. Mostly, I wrote about the problems I had running it on my main desktop which was running Mandrake 10.1 at the time. The error was basically a signal 11 in the log file, which MOST everyone says is a hardware problem (or kernel…) Well, I tested the memory, everything seemed fine. Finally, I was having other issues and an itch for an upgrade, so I upgraded to an AMD64 3000 based system with 1GB of memory and did the upgrade to Mandriva 2006 as well (first with the original kernel, now with the updated kernel.) Vmplayer still refused to run.

Qemu 0.8.1 (with kqemu 1.3.0pre7)
While I was testing out the “single cut and paste” linux vnc remote desktop sharing script and x11vnc binary…. I spent a fair amount of time booting up livecd’s n qemu to test various distributions/ages of linux setups to see how compatible things were. I had not checked in at the qemu site in quite a while (a few months), but there was a new version out… in fact, I think 0.7.1 is what I was running previously, so I missed 0.7.2 and 0.8.0… Anyway, I’m running 0.8.1 now and I compiled kqemu as well (now at 1.3.0pre7)…. wow qemu has made great strides (with kqemu) since 0.7.1 ….

Mozilla Firefox 1.0x series end of life….
The Mozilla Firefox 1.0.x series will no longer be supported with security updates. IF you use Firefox as your web browser, make sure you’re using the current version in the 1.5 series (currently 1.5.0.3). You can find what your current version is by going to Help, “About Mozilla Firefox”. The 1.5 series automatically downloads and installs updates and periodically checks for updates for the installed extensions.
