Traffic jams suck; but they do give you a chance to think and blog. Truckers hams are telling me that four trucks are totalled and need to be removed by the THW. As the trucker next to me just broke out his gas grill and several people are joining him in a spontaneous BBQ, I don't expect to be moving any time soon.
Kicking things along
Unless you are forced to support legacy systems or playing RAIDemon and gotta try them all, there is no valid use case for RAID 4. So doing so is a patently bad idea. RAID 5 is always the better option as you are not relying on a single disk which contains the checksums, but use striping to distribute them. RAID 4 has a chance of 1/n that a failed disk will force all remaining disks to read all respective sectors and then the controller/CPU to XOR everything. There is a reason why RAID 3 was replaced with RAID 4; just as there's a reason why RAID 4 was replaced by RAID 5.
Don't use RAID 4. Seriously.
Tom Tom vs OSM
In case you have been following the news in the GPS circles, you will have noticed that TomTom pretty gave up on innovating and resigned themselves to dying a slow death. Well that and to start a nice amount of FUD. While they have been rebuked pretty thoroughly already, I wanted to add my own POV.
There is a kernel of truth in what TomTom said inasmuch they state that pedestrian paths are better than car paths. Of course, while they got the relative quality right, they are wrong about the absolute quality of the data. They claim pedestrian is OK and motorized is bad. In my experience, maps for motorized traffic are good while pedestrian tracks are mind-boggingly great.
These days, most people (and probably all who read this) will be at least somewhat familiar with the quality of OSM in the random cities they visit over the year. The common verdict is usually "very nice".
But that's not where OSM shines. It's in the lesser-known places where you don't expect too many tech-minded people to come along where it starts to really impress me. While I found a few stubs on a dead-end street in Akureyri which were not mapped, every foot trail I ever walked along in Iceland has been mapped. ski-doo tracks on Svalbard? Check. Backyard in Novosibirsk? Check, as well. And we are talking "packed earth track in between garages opening up into a 'playground' where a man and a pregnant women are passing a bottle back and forth while smoking and watching over their two kids who play next to a middle-aged man who is lying on the ground wasted, using a rock as a pillow all the while an extremely blingy Mercedes with two muscle-packed thugs is cruising by, all in the time it took us to walk through". Mapped. Horse tracks and hiking trails in Mongolia? Yep. Hutongs in Beijing including alleys so narrow you have to walk single file? Of course.
Richard Fairhurst is right that the plural of anecdote is not data, but OSM is good. TomTom is afraid for a reason.
As an aside, I find the picture used in TomTom's newsletter extremely funny; I am sure they didn't intend this, but hey.
100-300 MiB for any random driver installation package is par for the course. Be it GFX, audio, or network card. If you plug in a different USB mouse, Windows 7 will take several seconds while "setting up" a standard USB HID device. And hitting ctrl-alt-del in the login screen or while logged in does not give you a quick way to shut down or reboot the machine. As I am breaking out the Windows installation every month to install updates and every six months to actually use this does not affect me a lot. Still, it's amazing that so many people are putting up with this.
It's nice to see that Matthew Garrett is still going strong. I am not sure if this is the best way, but it seems to be a workable solution while in between a rock and a hard place. Not sure about the requirements of GPLv3 with regards to the keys Fedora will use to sign GRUB 2 with. From what I remember without rereading the license, as long as Fedora is not selling a system on which you can not disable secure boot they should be in the clear. IANAL, IIRC, etc.
And I have not moved a single meter, other than making way to a police motorbike, in over an hour. Pity I don't have anything to BBQ with me; smells delicious over there.
