windows 2008 r2: missing wmvcore.dll

i guess certain video apps require a wmvcore.dll to be present in windows. the dll seems to be related to windows media player. anyways, to install the library in windows server add the windows feature “Desktop Experience” and reboot.

starcraft

replaying starcraft…

i can play all the way through the terran campaign without resorting to cheating. i remember having a difficult time on some of the later terran levels. for the zerg campaign i used a money cheat on mission 8 because i just wasn’t in the mood to deal with the escaping dark templars. i could probably beat the mission without cheats now that i’ve seen the entire map. i imagine first taking out the protoss base in the upper left hand corner and then the base on the middle right. you’d have to produce units as fast as possible though (which is annoying). protoss units can shred through zerg ground units so easily. maybe the trick with the protoss is using lots of mutalisks and guardians to disable bases and then sending in ground units to clean up.

wireless-n: 5ghz vs 2.4ghz

after skimming multiple articles online i decided to change my 802.11n network’s frequency to 5ghz. several articles pointed out that there’s much less interference on the 5ghz band, better performance, and overall that it’s the “preferred” frequency for 802.11n.

turns out that i should have read more into the articles. a big downside to using 5hz is that the range, quite frankly, sucks. i don’t see how you could maintain a usable wireless signal in a household with 5ghz, unless you pick the perfect spot in the center of the home. long story short i changed back to 2.4ghz.

tomato firmware evolution

the original tomato firmware hasn’t been updated in some time. it looks like development ceased on a promising tomato mod called tomatoUSB as well. however, tomatoUSB did add compatibility to newer routers such as the cisco/linksys e2000. there are 2 active mods that branched off from tomatoUSB that i’m interested in.
they are:
shibby – http://tomato.groov.pl
tomato RAF (victek) – http://www.victek.is-a-geek.com/tomatoen.html

these mods are at a point nowadays where they provide way more features than i’ll ever need. but still…very impressive stuff.

so eventually i’ll end up putting one of these tomato mods on the e2000. i have no immediate need to do so right now. i’ve also decided to end my brand loyalty to linksys after all these years. cisco has really ruined what was once an awesome company. i believe asus is much more in touch with the user base and whenever i upgrade to a 802.11ac router (probably 2015-2016) i’ll be purchasing asus.

update 8/3/2014:
i’ve upgraded to an asus rt-ac66u 802.11ac wireless router due to unforeseen equipment failure. i also have put the shibby version of tomato firmware (tomatoUSB) on the cisco/linksys e2000. after some research i felt most comfortable with the shibby branch – 1. because it’s still actively developed. 2. the maintainer seems to be a real developer and not simply a modding hobbyist. the exact filename i used was “tomato-E2000-NVRAM60K-1.28.RT-MIPSR2-121-Max.bin”. also of note is the fact that the shibby branch seems to cherry pick a lot of the useful features from the other mods…so you end up getting a very inclusive firmware.

dell poweredge r710 – sd card

the time has finally come where i need to move on to ESXi. i decided if i must do it, then i might as well install it on an SD card. so i went to check our r710’s and they don’t have the internal sd card module. what we paid for instead was the vflash for the dracs (that we haven’t even used yet). such a shame…

it’s not really surprising we missed this option on the r710 configuration page because it’s all the way at the bottom under “media”. on the r620 configuration it is much more visible under “internal SD module”. so we must not have been the only ones to miss it.

anyways, the good news is that they’re only 60-ish dollars.

i’ve noticed that you can download an esxi installer from dell and also vmware. so far, i’m not sure which route is the best to go (or even if there’s any difference). i’ll probably try out both.

raiser’s edge: deleting a user

vmware view best practices

  • keep base image as small as possible
  • lock down guest OS so end-users cannot write data outside of network shares
  • replicas stored on fast disks (SSDs or 15K), linked clones on slower disks
  • windows 7 image, 1 vCPU, 1GB RAM (2GB for power users)
  • suggested max desktops in a pool = 400 (verify)
  • per vmware max linked clones per VMFS volume = 60-90 (the closer to 60 the better)
  • anti-virus engines scheduled scans set to random (or off), possible real-time protection off
  • use vshield for virus scanning instead of desktop AV if possible

numbers:
according to an equallogic document, 78 virtual desktops ran optimally on a 2-quad core server w/ 96GB of RAM

example VDI servers from racktop “vbox” solutions –  http://www.racktopsystems.com/products/vbox/models

vmware roi/tco calculator – http://roitco.vmware.com

additional notes:
quickprep does not generate a unique SID, but it’s considerably faster than sysprep. sysprep can also still be used if desired.
SID is kept on refresh, but lost on recompose/rebalance

solaris 11: resizing swap partition

i was trying to install oracle database 11g on solaris 11 and ran into a roadblock. the install requires at least 1GB of free swap space. luckily i found a blog entry where someone else was having the same exact problem and posted a solution for it.

here it is in a few steps:
root@solaris:~# swap -lh
swapfile                         dev     swaplo   blocks   free
/dev/zvol/dsk/rpool/swap 124,2       4K          2.0G   2.0G

then remove the swap space with swap -d /dev/zvol/dsk/rpool/swap
i had to go to single user mode (init 1) to do this

then resize the volume with zfs set volsize=2G rpool/swap

finally, re-add the swap space with swap -a /dev/zvol/dsk/rpool/swap

my thanks to the blog author. also ZFS seems pretty cool i’d like to play around with it more some time.

vintage terminals with xscreensaver

a while ago i stumbled upon a really cool vintage terminal called cathode (http://www.secretgeometry.com/apps/cathode). unfortunately, thus far it’s only available for mac os x. i’ve been looking for a similar terminal for linux.

i haven’t really found anything that’s equivalent to cathode, but today i found out that 2 xscreensaver modules (apple2 and phosphor) can be used as terminal emulators like so:
/usr/lib/xscreensaver/apple2 -program bash -text -fast
/usr/lib/xscreensaver/phosphor -program bash -scale 2 delay 1000

anyways, it’s fun to play around with.
