Finally got a PC refresh at work. My new laptop is running Win 10. So far the only problems I've had were some issues with sound (found the setting to fix it), and desktop icon positions resetting on restart (not sure if fixed...). The navigation for the most part are similar enough to Win 7 to be fairly painless.

We'll see how it goes.

Just passed the first of 3 exams for the CCNP certification. Score was 790/1000, exactly at the pass threshold. XD

Funnily enough, I had no problems with the actual routing stuff (RIP, EIGRP, OSPF, BGP, etc.). It's the other stuff that stumped me. Like, what is even PPPoE and TACACS/RADIUS to do with ip routing? Meh.

I am shocked and appalled. Actually, I'm quite speechless. o_O



More info here. That first episode is just... pathetically... sad. OMG I don't KNOW these people...company... -_-

Also, I'm not sure advertising hardware that costs in the range of hundreds to tens of thousands of dollars using comics is really the way to go...

I got to admit, this is much more convenient (and cheaper) than me buying a bunch of flashcards and then making them by hand.

News passed around work lately. City of SF got locked out of their network by a rogue employee. Since apparently Cisco devices are involved, I've heard some calls and rumors flying around recently about it. I wonder if it's not just the computers/servers that got locked out, but even the routers, etc.

See, this is one of the problems with electronic security. Even if you make the hardware/software hard to crack, it's a double-edged sword when the security breaks down at the social side of the network that you can't design around.

The IETF (Internet Engineering Task Force) produces RFC's (Request For Comments) which are basically used to set the standards for pretty much all of networking. They define protocols from the physical level up, security standards, and so forth, that have become standard use by everyone.

And then they turn out stuff like this:

A Standard for the Transmission of IP Datagrams on Avian Carriers
IP over Avian Carriers with Quality of Service

Geek humor. :P

(More links from the wiki page for funny RFCs)

Remember these?

Snagged this from some interview talk. Fun to ponder. Try your wits!

Two of three of my Chinese BBS sites aren't working. Affects of the earthquake in Taiwan maybe? Hopefully the down time won't last for too long...

EDIT: Ah. According to Yahoo news it looks like this problem won't be fixed any time soon. Six of the trans-Pacific cables are down off the coast of Taiwan. Most likely it will take weeks to send ships out, bring up the cables, fix/replace them, and redeploy. I'm feeling the withdrawal already... T_T

EDIT2: I <3<3<3 CISCO!! I can access Chinese sites via VPN through Milan, Italy. Really slow, but it works!! ^_^

EDIT3: Someone sent me this link for proxy servers that can be used to access Chinese sites. I haven't tried them yet since that will interrupt intranet connection, but I'll probably try it at home and see how it compares to VPN.

EDIT4: Hm... by the time I got home I guess it's more or less a moot point now, as net connectivity is back up (albeit on a very very slow basis) with China. EDIT5: Spoke too soon... -_-

Suppose you have two rooms. In room A are three light switches. In room B are three typical desk lamps. Each light switch in room A turns on/off a different lamp in room B. The light switches can only be pulled to render a light on or off; there is no mid-way dimming function. The rooms are completely separate from and opaque between each other. And finally, there is no geographic correlation between the arrangement of switches in room A and the lamps in room B.

You start off in room A, where all the switches are pointing to off. You can do whatever you want to any of the switches. After you are done, you are allowed to go to room B where you can see the results of whatever you did. You are not allowed to go back to room A and fiddle with more switches after going into room B.

The question for this puzzle is: Which light switch toggles which lamp?

Not a good day today...

First had to drive to San Jose for the weekend on call thing because apparently their servicing some internal servers this weekend and I guess VPN might've been affected (of course, when I get there and open Outlook I see an email saying that everything's up and running fine).

And of course it was pouring buckets on the drive up. Which means I didn't feel like stopping somewhere to get lunch, resulting in my lunch being out of the vending machine. (Though ok, at around 2 o'clock someone sent around an email saying that some generous soul had gotten lunch for those of us in the building.)

Then I get saddled with four cases through the course of the day... which is what I get on a *busy* workday. Blah.

Then, I start my way home, and just as I'm about to get on the freeway, I start hearing this weird noise from the car. And I notice I can't accelerate. At first I thought it was the brake lever or something, so I pull over and check. Everything looks fine. I get back on the freeway and the noise becomes louder and ZOMG I hope it's not an engine problem.

So I pull off the next exit and park into the nearest corporate parking lot (with nice lights and security trolleys that run by every once in a while). I get out and check... it's a flat tire.

So much for plans to drop by Fry's on my way back.

A call home later, my dad comes and switches in the backup tire, and I'm pretty much paranoid the whole drive home.

This just ain't my day... *grumps*

So this was sprung on our team meeting today and I thought I'd share... It's the typical kinda question that you'd expect to come across in a job interview, I'd think... Anyway, the puzzle.

Suppose we have 4 people A, B, C, D all standing facing a wall (marked as '|'). Two are wearing red hats and two are wearing black hats. Arranged as follows:

A | B C D

Rules:
- No one knows the color of their own hat
- No one can turn around to look at the hats of anyone behind them or look at their own hat
- No one can see through the wall
- Everyone is aware of everyone else's general position
- Everyone can see everyone else in front of them up to the wall (eg. D sees B & C but not A)
- No one can move or otherwise communicate in a non-verbal manner
- No one can communicate verbally except except to state what color hat they themselves are wearing
- The person who speaks must be 100% sure of their statement (if that person is wrong then they all lose)
- Only one person can speak; the first statement must be correct
- Everyone is working together and aware they're all trying to accomplish the same goal under the same rules
- They have a 5 minute deadline; after which someone must speak or they all lose

So, how can these 4 people resolve this? Who is to speak and how can that person be certain of what color hat they are wearing?

...And how long did it take you to figure it out? ^_-


And the answer is... )

...ow.

Whining:

1. Bras and heels are instruments of the vilest torture designed to subjucate women to horrible pain and mutiliation for the sake of extended... measurements. *rolleyes*

2. Maintaining focus for about 8 hours straight for the training session with only a couple of 10 minute breaks plus a lunch hour... is hard. Must... not... zone... off...

3. Am I being too suspicious/paranoid/weird for noticing that of the 6 new hirees in our training group, all 3 of the females are also minority members/Asians while all 3 guys are Caucasian?

Silver lining:

At least I get paid well...

Hours (for cashew):

I get home about 7. By the time we're done with dinner and dishes, it'd be about 8:30 at the latest. I'm required to get ready for bed at 11. So that's about 2.5 hours I have free to do whatever... I know, not much time for Mud or whatnot, eh? le sigh.

Other notes:

My Windows tried to die on me today, claiming some Windows/System file was corrupted. The repair function on the CD-ROM wouldn't accept my password (grr). Then I gave up rebooting from disk and just let the damn thing boot again... and it worked fine. *crosses fingers* Hope it lasts 'til this weekend, when I can drag my dad to Fry's and buy some new harddrives to replace the old/nearly-full ones I currently have. This will also mean I will have to re-install everything on my computer again... but at least it'll be voluntary that way. -__-

I need a sulky icon.
