Dell Latitude E7240 and Intel Dual Band Wireless-AC 7260

Intel Dual Band Wireless-AC 7260 fails to notify Windows 7 when the SSID changes. The result is that the wireless interface retains the previous and possibly invalid IP addresses and other settings. The latest driver, A11, only a few days old, isn’t helpful at all.

I usually avoid installing Intel’s own utility for managing wireless connections, as I feel this should be left in the capable hands of the operating system and the driver. Maybe I should think twice about that.

The current solution is to manually force Windows into releasing and renewing the IP addresses after switching to a different SSID.

Running dns/bind910 within a chroot after r382109

dns/bind910 gained native chroot support in r382109. Those of us who used to store the BIND files in /var/named/etc/namedb and ran BIND with /var/named as the chroot environment, must do five things:

  1. Rename the /var/named directory to something else, like /var/Named. This is to avoid upsetting make -C /usr/src delete-old and still retain the meaning of the directory’s name.
  2. Rename the /var/Named/etc/namedb directory to /var/Named/usr/local/etc/namedb.
  3. Edit /var/Named/usr/local/etc/namedb/named.conf to reflect that the BIND files now resides in /usr/local/etc/namedb, as seen from within the chroot environment.
  4. Change the appropriate line in /etc/rc.conf to read named_chrootdir="/var/Named".
  5. Restart BIND using /usr/local/etc/rc.d/named restart, or start BIND using /usr/local/etc/rc.d/named start if the former fails.

Endless patch cycle in Star Trek Online

Since last night the Star Trek Online launcher has swung between patching 3808 KB, and patching 3034 MB, and in the latter case, the launcher stops when reaching about 1330 KB. It all began after patching the initial ~3 GB earlier last night. Endless patch cycles such as this one, was one of the reasons I left the game 5 years ago.

No, I don’t run STO through Steam, as those guys have different opinion of the integrity of the game’s files. The Steam client and the STO Launcher get in the way of each other at every opportunity, messing with the game’s files. That’s pretty bad until STO and Steam can finally agree on the checksums or whatever they use to verify the game’s integrity.

I’m attempting to download the game anew, using the bootstrap launcher, to determine if the cause of my problems is of an accumulative nature, or simply intrinsic to the current state of the game.

Update 2015-04-18
I tried downloading a fresh copy of the game, including the update released on April 16th. I can play the game, but the launcher keeps downloading the same amount of patches both before and after I play the game.

Some co-gamers have identified DirectX 11 as a possible cause. Others claimed success by forcing the launcher to use the US patching proxy.

I tried that the other day, both the EU and the US patching proxies, but all I got was nowhere, so I force no patching proxies atm. Turning off “On-demand patching” doesn’t help much either.

I’m sure PWE/Cryptic are fully aware of the issue.

Today, I created a new character and made that one a Delta Recruit. It is to some extent pleasing to (re)play the old missions I played both 5 years ago and again a ½ a year ago. This time I must make sure I also grab stuff relevant for a Delta Recruit. I wish there was some kind of continuity in STO, i.e. a way of converting or amending an already established character, e.g. a Level 60 Fleet Admiral, into a Delta Recruit and move on.

UEFI, GPT, Windows 10, FreeBSD 10, and rEFInd

Over the last few days have I experimented with UEFI and GPT in VirtualBox 4.3.26. The goal was to multiboot various operating system, in this case Windows 10 Enterprise Technical Preview 9926 x64 and FreeBSD/amd64 stable/10.

First, I thought of persuading the UEFI firmware to always present its boot menu. It sure beats remembering to press F12 each time I want to boot a different operating system. This proved impossible for a number of reasons.

Next, I came across The rEFInd Boot Manager. After a quick glance I saw this is exactly what I want, a UEFI boot manager. Continue reading UEFI, GPT, Windows 10, FreeBSD 10, and rEFInd

iTunes leakage or email address harvest?

I received a suspicious looking email today, claiming someone had made a purchase in Russia using my iTunes ID. A trip to iTunes revealed no such purchase. Nevertheless, I changed my password again, as I suspect this false claim might be the result of an iTunes leakage or someone harvesting email address in the hope that they are being used as iTunes IDs. Continue reading iTunes leakage or email address harvest?

Fagfolk og regninger

Problemet med fagfolk er at de har tilpasset regningene sine til besparelsen.

Fra en debatt om varmepumper i Teknisk ukeblad, mars 2015.

Sitatet er tatt ut av sammenhengen, men den treffer bra for de tilfellene hvor sluttsummen er astronomisk, og målene skulle blant annet være besparelser og effektivitet.
