Today I was with a group of students making a presentation to Siemens. They had emailed the PowerPoint two days ago, but they made a few last minute editorial changes and they wanted to upload a new version. They then take out a thumb drive and stick it into a Siemens laptop to run the presentation. My jaw dropped. Wasn't Siemens implicated in the proliferation of Stuxnet? You'd think that there would now be a corporate-wide policy against any unknown USB drive ever contacting one of their computers.

I thought Stuxnet was more targeted at the Siemens-branded industrial control(?) networks that Iran was running..

But yeah I bet if their IT guy had been there he mighta said somethin!

The folks I was dealing with are involved in testing new sites in North and South America. It isn't too many "degrees of Kevin Bacon" to get anywhere else in the world.

Just finished taking the stupidass general gre. Ugh..............

I got a 480 on the verbal (my weakness) and a 690 on the quanitative section. I could have done better on the quant section but I did a poor job pacing myself and ended up with 1 min to answer the last 5 questions. Doh....

According to the ETS percentage lines, that puts me right at the mean for "physical science" majors.



I'm pissed off and a couple friends arrived in town tonight for a visit. Time to get drunk!

Really hate my digital design class. Professor assigns ridiculously long labs each week involving Active-HDL, which I don't have because I own a mac. So I have to spend about 10 hours a week in a dark computer lab working on verilog code.

And I don't understand multiplexers.

(1) What is the required platform for your school? If it ain't Apple you are SOL. If it is, then you have a valid complaint.

(2) Is the software available to run in Free BSD? If so, then you are OK. Your Apple OS is actually a slick GUI on top of an open source operating system and you should be able to make it work with a bit of tweaking. Steve Jobs has made a well paying career from stealing good stuff that other people developed. Google "Xerox Parc" and you can figure this out on your own.

So what's the goto config for a media server? I'm getting a bona fide workstation to replace my clapped out desktop that's weaker than my laptop. The 'boss' said keep the desktop so I'm going to slap in some drives and set it up to hold music, video, etc. It's loaded with Win7 Pro right now. Just take it out of my work domain, remove all the vpn and security software, clean out the work data, load up the media and let it rip, or is there a better way? Help me 33 nerds, you are my only hope.

I'm expressing it poorly, but I think apple has a higher opinion of itself than is merited, a bit of a holier than thou attitude, and it bugs me a lot.

+ a couple dozen. They are beyond smug.

My girlfriend, who is in Australia right now, asked me to look up the price of the 2.66 ghz 15" Macbook something or other (she kept getting redirected to the Aussie site). Looks like 2100-2300...I think that's a little pricey, myself.

Not exactly what you're looking for, I don't think, but take a look at this anyways - it's a nice little project.

Hot swappable RAID.

A lot of overhead on the power supply so you don't fry the machine.

Lots of on-chip cache if you expect a lot of concurrent connections.

It can be done with a Windows OS, but a Linux OS is better.

I was having DNS problems with BF sometimes, so I posted a thread in the help section of this website.

Turns out you can configure to a public DNS server instead of using your ISP automatically. I configured to Google's DNS servers, and everything is much faster now. Google pages (calender, mail) are ridiculously fast.

Definitely worth trying out. It's under TCP/IP settings for your particular connection (wireless/wired, etc). Google is 8.8.8.8 and 8.8.4.4.

mollusk 10-22-10 10:27 PM

Google tracks me enough as it is. I don't need them to know every freakin' IP address I need to resolve.

It depends on what OSs you run at home and your level of technical sophistication. If you largely use Windows boxes, then Windows Home Server can't be beat, although I'd wait for Vail to come out before buying an OEM license for it.

If it's Linux and OS X at home, a nice FreeBSD or Solaris box with ZFS and RAID10 would be my choice.

Just rolled thru the first "practice run" for my seminar on Monday.... 62 min which is perfect, because i'm sure in my nervousness on Monday I will speed things up and omit sections to fit it into the 45-50min window for an A.

Also I didn't look down at my notes once, which is sweet. Time to unwind on BF for 20 or 30 and go give it another run.

What's the seminar on?

TMonk 10-23-10 11:37 AM

It's my senior project/capstone course:

Title:
Conjugated organometallic polymers: A description of the synthesis and photophysical properties of organic semiconductors featuring a new cyclometalated platinum moiety.


Abstract:
The general properties and photovoltaic parameters of organic semiconductors are introduced after a brief comparison with traditional inorganic (silicon) solar cells. A new class of cyclometalated platinum polymers is introduced in which the primary chromophore is the Pt-Polymer coordination bond. Synthesis, device fabrication and compound characterization are described for two specific Pt-polymers with power conversion efficiencies approaching 1.3%.

Reserve me a spot

TMonk 10-23-10 01:02 PM

Just finished round 2 of practice.... 55 min with no hesitation and deliberatly quick speaking.

Looks like I'll fit right into that 45-50 min indo when I add the game-day jitters into the equation.

carpediemracing 10-23-10 01:23 PM

Good luck. I had to slow down and read word by word when you described what you'll be talking about.

I feel... monosyllabic.

All I can tell is he's making an organic solar material... and I'm an Electrical Engineer...

I didn't even get that far...

I did manage to refactor a giant chunk of code on the flight from Nice, however. Some cron magic and DB tweaking and one table shouldn't be getting slammed with requests quite so often

Phew. I recognize "cron". I was talking with the Missus about my old life (Linux/Unix build/support) and couldn't really remember much of what I did (ended about 3 years ago). I may have to build a machine for myself so I don't get too rusty. Ubunto laptop (I want to do that anyway on an old one), Redhat "server" (on my current "backup" machine).

This is how I feel when a lot of you guys start talking in computer programming lingo.

To Clarify this (by dept. requirement) is a presentation on someone else's research. It went down at the end of last year at UC Berkeley.

Probably not, because this is a solid state material with no charged species in solution.

Once the polymers are synthesized, there is no chemistry involved in the generation of photocurrent. There is no reaction taking place to generate electrons; it's just excitation of one species: the "plastic" semiconductor.

Enthalpic 10-23-10 09:30 PM

For polymer photocells to save the world we need to get away from Pt and other pricey crap. Need a Fe or Mg compound cheap enough to print; but this stuff is a good start.

Flatballer 10-23-10 09:37 PM

the conversion efficiency is also still quite low. Needs a lot of work there before it can compete with the likes of thin-film. Thin-film is already pretty cheap, getting cheaper all the time, has high efficiency, and can be made in all sorts of configurations, some of them very flexible and unique.
