It works fine but when you turn it on it instantly starts making this high/low octave alarm and doesn't stop.
Thankfully I found the problem. There was this piezo electric buzzer soldered on the board. Now that I've broken that, everything is functioning normally.
mounted inside a PC case made of transparent plexiglas.
Transparent aluminum... duh!
So what? RAM is cheepo.
(Stallman joined the hacker set quite late in the game and resorts to extremism to make up for it.)
I want to build that. I can swipe an ir led from any remote, right?
I pulled up the user-guide on HP's web site and it says the interface conforms to IEEE-1284. The guide lists the following cables:
3 meter, part # C2946A
10 meter, part # C2947A
Here's the URL if you'd like to download it:
And the info about the cables is on page 48.
But let's also point out we're comparing apples to oranges.
vbox is like vmware desktop, those two you can compare, and I think vbox is a close second, but vbox isn't even in the same category as the other vmware products (whatever they call esx and gsx nowadays)
The company my wife works for decided that they needed an Internet connection.
After some searching and questioning of neighbors, they settled on DSL from a local provider. After some back'n'forth with the provider, the day finally arrives when the DSL is supposed to be turned on. The DSL modem had already been shipped and had arrived at the office. They go to plug in the modem and can't get it to lock onto the signal no matter which wall jack they try.
This is a very small company with only a part-time IT guy who only works third shift, and the DSL needs to be active ASAP. Thus, my wife asks if I could help.
I grab some tools that I think I'll need: punch tool, RJ11/RJ45 crimper, RJ45 line tester, tone generator, and a small bag of RJ45 connectors. I get there and, lo and behold, the modem definitely won't train no matter which jack I use. They have a "patch panel" in the adjoining garage, which is basically a mess.
Anyways, after sorting out what's what, I realize that I need to use the tone generator to tone out which pair is coming in from the junction box on the side of the building into the office, and which pair I can use inside the office to connect to a wall jack for the modem to plug into.
The problem: the tone generator I have only has an RJ11 jack. This is great as long as I have a another RJ11 jack to plug into, but leaves me with no way to connect to the punch blocks in the garage or the junction box outside.
The solution: A quick trip to Radio Shack to see what they have. I end up getting a modular telephone connector (one of those big plastic blocks with an RJ11 jack on one side, and four brass posts on the back) and a pack of test leads with alligator clips. Plug the tone generator into the modular connector, attach one end of the test leads onto the modular conector's posts, and the other end to the punch block. Voila!
The smack my forehead moment: After toning out everything I needed and punching down the right pairs, I go to put the tone generator back into its carrying case and, lo and behold, there's a pre-fabricated adapter with an RJ11 plug on one end and test leads with alligator clips on the other!!!
Let this be a lesson to all those who have never done this kind of work before.
Make sure to unpack everything first! You never know what you'll find that you may need!
whew. now this is a bad thing. coincidence?
yesterday late nite such a talend alike train collided with a freight train.
this is the freight engine:
its even older than the 218 pictures i've posted before.
Which is why I'm not rich. :( And the SIP thing makes sense too. Somewhere someone must have written a simple SIP gateway, easier than asterisk, so that you can use your wifi sip handset behind NAT...
Speaking of our genius DBA, I was somewhat surprised that sybase didn't have cascade delete, and because of some reason I forget I wanted to delete stuff in the cascade delete order, but the foreign key constraints the DBAs put on my tables didn't allow for that.
So my sprightly (spritely?) dba told me he'd write a trigger to implement cascade delete
Scratching my head I wondered how this was going to work without removing the fk constraints. After much banging his head, he let it drop, as in gave up, and I still have to delete my stuff backwards.
Shouldn't be that hard. But it is, it always is.

The conundrum of data center operations:
Reliability requires redundancy.
Redundancy introduces complexity.
Complexity reduces reliability.
Solution: self-reinforcing simplicity
Ah, yeah, I could see that being annoying.
the waledac botnet was just killed by microsoft and some other parties...
they switched off the DNS via judge and captured the control servers...
They should probably ask themselves why they're still using tape media :)
