I had a set of Firefox windows and tabs open on my Windows 7 laptop. I was in the middle of one thing when I started an unrelated effort to rebuilt a secondary disk to allow the laptop to boot MacOs and Ubuntu. I knew I wanted to preserve the session of Firefox windows for my other effort so I was using Chrome to keep the two projects separate. Somewhere in there, I installed new software which automatically opened Firefox and then I rebooted effectively killing off my ability to use Restore Previous Session from the Firefox menu. But I wasn’t ready to be done with those tabs! So I dug around in the Firefox folders and figured out how to restore the session I wanted. Here’s what to do if it happens to you in the latest version of Firefox.

Shrinking a USB Disk Image and Burning to Disc
I successfully installed MacOS on my Dell Latitude E6430. With that complete, I wanted to make an DVD archive of the USB drive I used as the installer. I have DVD archives of my past hacintosh installations and to keep up the library and to keep the permanent backup, I wanted one for this install too. This task proved to be impossible and impractical and good golly I wasted a lot of time on it. But since I learned a lot on the way, I needed to write it up. I’ll forget it if I don’t and some of the lessons learned can be useful for the future. Primarily for me, but perhaps for somebody else too.
Triple Boot E6430, Sort Of
I’ve got my Dell Latitude E6430 booting Windows 7, Ubuntu 14, and MacOS 10.11. I’ve done this before with this computer but it wasn’t ever really stable and I didn’t document it because I hadn’t gotten it the way I wanted. I’ve also done it before with earlier versions of these OSes on my previous computer, the Dell Latitude E6410. But it wasn’t until today that I got a set up with the E6430 working the way I wanted. And although it cheats a little by using two disks, I do get all three OS on a GPT disk booting using UEFI. Sort of.
Resurrecting a B&O Turntable
My Bang & Olufsen turntable had been stowed away for years. It always lived prominently on top of my A-V rack. Of course, a turntable needs to go on top so the lid can open all the way. When I got my first plasma TV, the TV was so wide, it chewed up space not only on the center rack but on both side racks too and that meant nothing else could go on top. But I wasn’t listening to vinyl anyway, so the turntable was packed away.
But vinyl is hip now and I had now “archived” other components such that there was now room on a lower shelf for the turntable. No, the lid can’t open all the way. But it opens enough to get a vinyl record in safely. I put the turntable there a year ago but didn’t plug it in. I didn’t have time to futz with that stuff at the time. Last year for Christmas I got a record (original “Boston” album on picture vinyl) and I put getting the turntable working again on the to-do list. Now, nearly a year later, it finally got to the top of the to-do list. Time to dust it off and plug it in.
Migrating Windows XP To SSD
One of my family members is still using Windows XP on an older computer and they got a “no boot device found” error. Apparently the hard drive had finally given up. But the computer does what they need it to do and they don’t want to buy a new one and of course, there’s stuff on the hard drive that they didn’t want to lose. Here’s what I did to get the system disk switched to an SSD and get them back to where they were before the hard drive failure.
Migrating from Subversion to Mercurial
I have an old computer that I had been using as a subversion server. Before the computer fully fails, I decided to move the subversion repository off the computer. Rather than putting it on another computer, though, I wondered if I still needed a server for source control at all. As a small business, having less hardware to maintain/manage is better for me.
At first I wondered if I could use an NAS or similar device to function as a source control server. I found some reports indicating that you could hack an NAS to add in subversion server capability. But that’s not what I had in mind. I was wondering if my laptop could effectively be not only the computer that I use to write code but also the computer responsible for storing code. Now I didn’t want to make it a server, per se, where other computers could theoretically use it as a server. But I thought the computer might be able to handle storing files to a repository, like an NAS, on its own.
RAVPower FileHub RP-WD03 Seabird
I’m pretty excited about this little black box I got recently. It’s a RAVPower FileHub. The codename is “Seabird” and the model number is RP-WD03. “FileHub” isn’t quite descriptive enough, though. Primarily, I got it to be a hub of files, that is true, but it’s got a lot more going for it.
MythTV User Job for Exporting to SD card, Revisited
Less than a year ago, I figured out how to export TV from MythTV to write to an SD card for taking TV on the go. I did eventually get things to work but even after all my effort there, I wasn’t getting the video compressed at all. Also, it took a long time just to write the video to the SD card. I wanted to improve the overall process.
Static Solution for Desk
I recently moved my office in the house to a room that’s going to work better for me. I spent a lot of time working out the desk area and planning the desk surface and the chair area. It’s worth it to plan because my butt spends so much time parked here. The room was already carpeted and I didn’t really want to pull up the carpet – at least not at this time. I kind of like the sound deadening that comes with the carpet and the floor underneath is nothing great. But that meant I needed some sort of solution to having the chair roll around. I tried just on the carpet and as expected, the chair squished in. It was hard to move the chair and I was pretty certain the carpet would be wrecked within a few weeks.
Monitor Problems on the Hacintosh
About a week ago, sitting at my hacintosh, my wife had come in to ask me a question and as she stood in the doorway to the office, the second monitor image suddenly got sort of zapped (like you see in TV shows when the bad guys take over the TV feed that the hero is watching) and then went dark. The main monitor flickered and then returned. And no matter what I did, I couldn’t bring back the second monitor. The display was still effective in that I could move windows into the darkness and the windows that were on that display didn’t move to the main display. Downright freaky.
