Crazy Perl Day
I’m surprised that this is the first time in Perl that I’ve bothered to use the posix character class [:alnum:]. Check this nuttiness out: ($::port_name, $::first_port, $::last_port) = $::port_range =~ /([[:alnum:]]+[^[:alnum:]])(\d+)-[[:alnum:]]+[^[:alnum:]](\d+)/; Yeah…it’s better with coffee.

My Pogoplug Thinks its in China?
I think I have to set a regulatory domain for my usb ath9k module because it appears to think it is in CN, which I’m assuming is China. [ 43.313192] usb 1-1: ath9k_htc: Firmware htc_9271.fw requested [ 43.331335] usbcore: registered new interface driver ath9k_htc [ 43.588793] cfg80211: World regulatory domain updated: [ 43.593951] cfg80211: DFS…

SourceForge is making Open Source Look Like a Scam
Not only when I download something from SourceForge these days am I presented a proxy-downloader that tries to sell me on installing some unsolicited system utility — like a browser home page take over — it manages to install some other bullshit system utilities as well. Holy shit. This is not the Sourceforge I used…

IntelliJ configuration notes on using HugePages
Java has supported Linux Hugepages for a while, but it is not on by default. I like to squeeze the most performance out of my IDE so I turned it on. And here are the settings I used for Intellij now: > cat idea64.vmoptions -XX:+UseLargePages -XX:LargePageSizeInBytes=2m -Xms256m -Xmx768m -server -XX:+UseG1GC -XX:MaxGCPauseMillis=15 -ea -Dsun.io.useCanonCaches=false -Djava.net.preferIPv4Stack=true -Djsse.enableSNIExtension=false…

Pogoplug now running hostapd
I was not anticipating it not being able to reach channel 11, so I set it to channel 1. Also, it cannot do 802.11n, so I set it to 802.11g. My cell phone seems to be able to use it. Also, for some reason, my pogoplug syncs up to the same switch better than my…

Hostapd : The Linux Way to create Virtual Wifi Access Point
Originally posted on Foo, Bar and Foobar: NOTE: Although this guide should work in most cases, it is not flawless and still requires few minor modifications to make the process bug-free. Please do point out corrections and changes. (After you are done with this post, please do checkout my Python Hostapd Client) I was recently…

Time Machine on a network drive
Helping a friend setup time machine backups to his new NAS device. Reasonable howto so far. Time Machine on a network drive. Unfortunately, when you see some of the examples of how to get ‘computer name’ and ‘drive name,’ you might not get familysomething.local as your hostname, it might be ‘familysomething.routerbrand.com.’ Why familysomething would gain…

Raw ZVOL access in ZFS on Linux not an option for VirtualBox?
I have gotten about as far as I can go…I can boot a Fedora netinstall cd, and I can attempt to fdisk /dev/sda, but this device will not open in fdisk. This might be consistent with no “rdsk” device in the dev tree. Funny though, I can fdisk /dev/zd0, and it lists partitions. Could this…

Converting Virtualbox disk to ZFS volumes
I am trying to create zvol backed virtualbox guests using ZFS on Linux. Hopefully this is not too ambitious. Find size of original .VDI disk image: vboxmanage showhdinfo Fedora19.vdi Pass that file size into zfs create: zfs create -V40960M tank/VMs/Fedora19 Convert .vdi file to raw, best if you can do this from one hd to…

Ford…Fairlane?
This might have been a 1964 Fairlane, but the details (like bumper blinker) do not match images I found. This was one of the two vehicles abandoned on Jay and Ellen’s property from previous owners. There are so many bits of nostalgic junk back there that I could be in photo subjects for a straight…
