Control Ingress (incoming) bandwidth... with Bittorrent and others

I wanted to download a file, but we just got this awesome high speed fiber optic internet...

Great Format for Instructions (Setting up UCSPI-TLS on Qmail)

This instructional page I just worked through about setting up UCSPI-TLS with Qmail was really good. It has all the steps, and they're numbered and indented. I just think it's a great format for "howto"s, because if you're discussing it with someone else, you can refer to a specific step.

Got Semi-Scammed by Discount SSL Vendor Comodo with "PositiveSSL CA 2"

(Just to be fair, I think the SSL cert business is a scam, so there.)

Vanishing Window Managers? LOL

I think Windows sucks, but one thing is for sure - the windows are there.

Virtual Machines that are Less

So I was looking around the Hyper-V manager and doing it over RDP in a Windows environment brings out some contrasts between server and desktop computer requirements.

Upset About Acer Recovery Disks, I Found a Lame Solution

I have been helping someone recover from some reckless Windows usage. You know the situation: lots of colorful apps that want you to pay for registration, and a bunch of random viruses.

Microsoft Server 2012 Licensing Humor

It's only funny in a SMH way.

More Impressions of the ZyXEL ZyWALL USG-50

I've finally started to work on the network because, while things are heating up at work, I'm mostly on-call for the next week. I have some time on my hands to experiment.

OneNote Shared Notebook Corruption Leads to Cache File Problems (onenote notebook cache file 0xe000012e)

I was having problems with an error reporting corrupt OneNote cache files. It turned out the problem was at the server that was sharing the notebook. OneNote saves notebooks as folders full of files. The quick fix is to do a copy-paste of that folder, name it something like originalname-2, and then open it in OneNote.

Microsoft PowerPoint 2010 AutoSave Doesn't Work, Even With Some Crashes

Unfortunate news: even if you have the autosave option turned on, PowerPoint isn't really making an autosave document that will persist after all crashes. Even worse, if you exit, and it tells you that if you don't save, you'll still have a draft, you won't actually have a draft. PowerPoint seems to delete its temporary files when you exit the program. When I tried to kill PP, it still deleted the file. So that bit of cleanup code is pretty resilient, at least to my half-hearted effort to blow away PP.

Visual Voicemail via IMAP

I came up with a quick idea - visual voicemail similar to Apple's iPhone - via IMAP.

Windows Offline Files Suck (today)

Windows ships with Offline Files (aka Offline Folders) on, more or less. These things suck, mainly because they're a little unreliable, and seem to lose data, or files get wedged and won't sync.

1 Reason Why Exim4 (and other Unix MTAs) Suck

Though I'm now officially an Exchange hater, there's still one thing that really sucks about running a Unixy email server: authentication and encryption.
