Tired of Blogging

I've noticed something about bloggers. Some are born to blog, some blog because they can, and others just blog. I have finally come to the conclusion that I belong to that third category. What I had expected to be a source of fulfillment has mostly proved just to be a drain of energy. I actually enjoy reading the writing talents of others and commenting much more, so from here on out I will focus almost exclusively on that.

VirtualBox straining out a NAT

Sun's VirtualBox 1.6.2 no longer allows my NAT trick using the IP address 10.0.2.15. -Sigh- Not sure if it was a loophole in the code I was exploiting, or what. On the other hand, using the officially recommended way of sharing folders through the VirtualBox extensions works great (imagine that), unless on my machine when not running as root, then it is slower than dog-slow (but I think that is due to my machine's configuration somehow).

EDIT: It was 10.0.2.2, not 10.0.2.15, but no matter; it briefly worked earlier this evening (not sure how or why), and now has stopped working.

Fractalicious

http://www.aomin.org/aoblog/index.php?itemid=2744

I love fractals. I'm not sure why; perhaps I have a mathematician gene or two without my knowledge comfortably tucked away in my DNA. But I have loved fractals since the first day I learned of them. I am fascinated that the "ugly" (not really, but it has always been my mistaken first impression) science of mathematics can produce beauty, even art. But I look at fractals and think, "math did THIS?" The conclusion for me is inescapable.

Mathematics is beautiful. And I know precious little of it. But I am convinced that mathematics shows us a glimpse of the infinite mind of God and the beauty of reason, as far as finite beings such as ourselves can understand.

I cannot help but wonder what deeper discoveries in mathematics await us, which God so far has hidden.

About:Mozilla

I am excited as I can see Firefox 3.0 on the horizon. Browse to about:mozilla to see the interesting scripture from the book of Mozilla. I use both browsers (both IE and Firefox are excellent in my view) but I prefer Firefox, and I am not sure why. Perhaps you can accept I was predestined to do so.

The Blessed Gift of Salvation

The necessity and excellency of God's gift of salvation have both weighed heavily on my mind in recent days. The world is lost and dead in sin. Without Christ there is no hope, no light, and no rescue. My personal belief and full conviction is that only Christ can give us redemption, and the redemption He offers is perfect and complete. He has offered to God the perfect sacrifice, Himself who knew no sin, to make us who believe in Him acceptable to God and to separate us from our sins which in Him are paid in full. We are sealed with promise by the Holy Spirit of God waiting for a sure home in heaven in the bosom of the Father with all our hopes resting and wonderfully satisfied in Christ.

I am making a personal exception and posting this message to both blogs, even though the Byroniac blog is technical in nature, because of the importance of this message.

Please, if you are not a Christian (or even if you are!), take the time to read this site and consider it carefully.

Two Gripes

Two gripes about FreeBSD so far.

Full Disclosure: I'm running FreeBSD 7 under VirtualBox 1.6.0 (recently rebranded under Sun).

1. It runs DOG slow in Gnome (technical term, indicating an overall qualitative analysis rather than an actual quantitative measurement; in the common vernacular, this could be termed "slower than molasses" etc).

2. No sound. No clue why. I'm guessing the VirtualBox emulated hardware is not fully supported by FreeBSD. I might drop back to 6.3 and see if that's better.

I always did like FreeBSD (well, when it works, that is).

EDIT: Changed "X-Windows" to "Gnome" for accuracy. I'm not really sure what I'm doing, but running plain X via "startx" is fast enough, but running the Gnome Window Manager on top of X-Windows via "gdm" is like, painfully slow.

Six hours after I needed it

It would be so nice if I would learn to read the comments section of news articles before running off to try whatever fancy suits me at the moment.

I found a great link to a custom-made DVD ISO of FreeBSD 7.0.

Six hours after I needed it.

To FreeBSD Or Not To FreeBSD

<rant>
Arrggghh! Why on EARTH does the stupid FreeBSD partitioner think I only need a 69MB Swap partition???? What does it think it is installing on, a 486??!?!?!
</rant>

OK. It's not stupid. But I sure was. I missed this, and it caused SEVERE slow down on my system. The stupid thing is, I didn't notice this the first, second, or third times I installed FreeBSD, ran into problems, and restarted. But strange things happen with insufficient swap space, such as losing your mounted cd media in the middle of installing packages for example.

Right. Blasted it for the third time in a row and started the reinstall. This time, I created an appropriately sized swap partition, and threw everything else into a single partition mounted as root (/). This is probably not a good idea, but it's a VirtualBox hobby-sized project, so it probably does not matter.

Creating Your Own FreeBSD 7.0 DVD

Creating Your Own FreeBSD 7.0 DVD

I will simply have to try this for myself.

I'm currently installing FreeBSD 7.0 in VirtualBox, and I couldn't decide what I wanted, so I told it to install practically everything. That means swapping from ISO image to ISO image as pkg_add wants files, and it's simply tiring. As an aside, once it's installed, I'm not sure what to do with it. Most of what I know is Windows-based and Linux-based, and I need to learn a LOT more.

If I survive, this should be fun.

VirtualBox NAT folder share in Linux

Oops. I forgot the Linux part of this post.

In my Linux guest OS (Fedora 8), I changed two files to get NAT file sharing to work.

Added host computer name to /etc/hosts:

10.0.2.2 czflmc1

Added folder shares to /etc/fstab to auto-mount:

//czflmc1/C$ /mnt/C cifs auto,rw,user=dude,pass=x,uid=500,gid=500 0 0
//czflmc1/D$ /mnt/D cifs auto,rw,user=dude,pass=x,uid=500,gid=500 0 0

Works like a charm! YMMV... (Your Mileage May Vary)

P.S. I had to create the /mnt/C and /mnt/D directories as root first.

VirtualBox NAT folder share

Interesting tidbit about VirtualBox NAT (Network Address Translation) file sharing. NAT networking is exceptionally convenient because it doesn't modify your host networking settings but shares it with the guest OS. I was trying to figure out how to share SMB/CIFS folders from my host OS (Vista SP1) to the guest OS (Vista SP1, don't ask me why, I just wanted to), and the Personal Shared Folders via the Guest additions wasn't working....

Solved it: the guest NAT network is 10.0.2.x and sure enough, I can map drives through the address 10.0.2.2 which is the NAT gateway or domain server (forgot which, but it reaches the host). So now, I can see shared folders on the host through the NAT network, without having to use bridged networking or the VirtualBox additions (installed, but not working for the personal shared folders on a Vista SP1 guest OS for some strange reason). And my host doesn't need to see the guest as an individual IP, so... woo-hoo!

The Three Wise Men Do America

Actually, they're Democrats, not wise men. At least two of them are, officially. And two of them are men, at least technically. And they all want to do America. But not officially. Or even technically, in truth, because they're just playing the political numbers game we crazy Americans get caught up in every so often. Perhaps they should just figure out whose turn it is, and be done with it. That would save us several months of wasted television electrons for half-baked promises that quite honestly would probably look best when remaining on the theoretical blackboard.

Right now these three Democrats are the ones to beat in America: Zerobama, Shrillary, and John McVain. And I'm having trouble choosing among them, but not for reasons of popularity or personal appeal. I'll have to pick one, so I guess it will be McVain. I'm pretty much a die-hard, disillusioned, disgruntled Republican with no real party loyalty who still votes faithfully Republican. What does that make me, except a non-renewable political resource?

ZeroBama - I still don't know what to think about him. I'm not saying there's nothing he believes in. It just seems that he believes very passionately in nothing in particular.

Shrillary - Her voice has the really pleasant and soothing qualities which remind me of iron scraping concrete. And I remember when she was President the first time. :) (And, am I prepared for a First Man? Spouse to America's first Queen? Um, no.)

John McVain - "Don't judge a book by its cover" can also mean that the book cover wasn't worth the price tag, never mind the filler in between. But it's not polite to point out the other side of the coin, so I'll refrain. Oops, too late.

It's no wonder every day of the week might as well be Monday, and I feel like sleeping in.

P.S.

(I didn't want to post this on my theological blog, even though this blog is technical in nature. So, anyways, without creating a third blog for miscellaneous miscellany, this is the best I could think of. I need some serious social and political inspiration, and I'm just not finding it in the mainstream political parties.)

Ubuntu Linux under Windows

http://www.pcmech.com/article/how-to-install-and-run-ubuntu-linux-inside-windows/

Interesting article. There's no reason I'd post it, really, except I'm trying to (cough) win (cough) converts (cough, cough) for Ubuntu (hack, cough) or at least Linux in general (wheeze). I mean, please ignore this entire blog post unless you want to venture dangerously close to something cool.

That's it. Nothing to see here. Move along. (Hint: clicking the link above will accomplish this nicely).

User Account Control (UAC) - Elevate Privilege Level (Vista x64)

Here's a very interesting tidbit on automatically elevating privilege level on applications in Vista 64-bit, while avoiding that bothersome prompt (works in 32-bit, too, which is what I have).
