Looks like I should read my MSDS more often... FC-77:
ATMOSPHERIC FATE: Perfluoro compounds (PFCs) are photochemically stable and expected to persist in the atmosphere for more than 1000 years. PFCs have high global warming potentials (GWP), exceeding 5000 (100-yr-ITH). The Ozone Depletion Potential (ODP) is Zero.
HFE-7100:
ATMOSPHERIC FATE: Zero Ozone Depletion Potential (ODP). Atmospheric Lifetime: approximately 4.1 yrs. Global Warming Potential (GWP): 280 (100 year ITH, IPCC1995 method). Global Warming Potential (GWP): 320 (100 yr ITH, IPCC2001 method). Atmospheric degradation products are expected to include: for methyl nonafluoroisobutyl ether: predominantly isoperfluorobutyric acid, CO2, HF, and perhaps also CF3COOH; for methyl nonafluorobutyl ether: n-perfluorobutyric acid, CO2, and HF.
The HFE was developed to address the environmental persistence of FC by photo-decomposition. The byproducts, however, still look to be a BadThing(tm)
really? my bad then. my experience is with FC-77, which as a perflourocarbon should be a ozone eater... I (wrongly) lumped 73 in with it. Off to do some research to ensure I didn't just lie;-)
FC77 and 73 also are longterm environmental hazards and attack the ozone layer. Which is why the HFE family was invented. Like most things of this ilk, the older stuff is better for the task (R12 Vs 134a anyone?)
I use FC77 and HFE7100 as thermal transfer fluids for ultra-cold applications (-60C and lower) in semiconductor testing. Wicked cool stuff.
IF you do manage to buy/acquire enough HFE7x00 remember it eats plasticizers for lunch (gloves are almost useless, better just to be careful). As such I strongly recommend glass enclosures with as few seams as possible (bend two horseshoes of glass fit them together very tightly then seal with a torch). Obviously a hole for the MB to slide in would be helpful. A tight fitting lid will help to reduce evaporation.
I'm already thinking as a fourth monitor, mounted at a slight (nearly flat) incline behind my keyboard for my AV work as a touch digital slide/jog/shuttle board...
Sure that looks like a better solution, but squid over a linux router is easier and "good enough". My caveat is that we have a strict usage policy and if you are caught circumventing my "good enough" solution you are not going to like the written warning. If you want general internet access you are expected to use your notebook and WiFi connection, and not connect to my lab network. -nB
I hit I/O throttling when I do the following: * rip 2 dvds (two DVDR Drives) * transcoding previous DVD rips to XVID * Moving completed rips to server over 1 Gbps Ethernet link.
At this point I can see CPU load start to drop as PCI bus I/O saturates.
At no point do I hit disk I/O or memory limits. Disks are non-RAID non-striped, but rips are to separate disks (thus DVDA rips to HDA DVDB to HDB) and server upload pulls from whatever disk is not currently transcoding (transcode file on HDA, when done start transcode on HDB and move file from HDA). -nB
how about we still protect their IP as you rail against, but bring the terms of protection back down to their original terms, or even better, shorten them? Would that be reasonable?
Think of the work that goes into making the studio recording. Those folks deserve a cut. They won't get a cut from the live performance, so buy the CDs and let them have a piece, don't just make it free.
Now, none of this is to defend the RIAA, they are evil, no doubt. But abolishing copyright all together would do more harm than keeping it as it is IMHO. -nB
no, I think he was more commenting on the fact that a 13 year old just as well could pretend to be 40 and a father of 6. I'm betting that he won't pull it off for long, but I wouldn't base any specific parenting actions from this site either. It's not a comment directed at you, it's a comment directed at the internet.
Mine is sitting on my server... Have not rebooted it since I moved (~1 year) really, I think it's power issues. This same router gave me tons of greif at my previous place, but when I moved I put it on the UPS and no issues since... -nB
The thing is, the act of faith means accepting the book as literal truth. If you have that level of faith, then nothing is going to shake you from it.
Really the issue at hand is not whether your faith or absence thereof is "right", it is that faith does not belong in science class. Faith belongs in church, and at home, and in bible study groups. Faith belongs in your heart, with your friends, not in science class. What I would not oppose is a theology class in schools as an elective, much as political science is an elective. If the student wants to take said class and learn about different religions of the world, possibly with guest speakers from various faiths (Muslim, Christian, Sheik (sp?), Buddhist, Flying Spaghetti Monster, etc.) that's fine with me. Just call a spade a spade, it's not science, it's theology and faith. -nB
A flight I was on within a couple months after 9/11 (Jan 02) the pilot came on the intercom pre-flight and thankd everyone for flying with him. He also noted that should anyone try anything "funny" he would like to remind the rest of the passengers that there are more of them than any bad guys that may be aboard. This was met with resounding applause.
Also, note that the fire extinguishers placed in well marked, easily accessible locations, make excellent bludgeons and the spray is good for a short term blinding as well. -nB
we use geographic location, task, sequential number i.e. LOCPRINT001 LOCWEB003 LOCLABNET004 etc. while this is not the absolute ideal from a naming practices, we have well over 200 sites around the world. that LOC string is very very helpful to knowing what the problem is. can't see any LOC for a particular site? Our admins will know, just by the absense of a block of servers that the site is likely fine, but the link to the TelCo is not...
That makes me so, so sad. My wife and I have had long discussions about that very topic, and we've both agreed that sex/nudity/etc. is ok for the kids to see, but Violence is what we want to protect them from.
That my 5 year old daughter knows she has a vagina and that her brother has a penis actually offends people. My son (3) also knows the appropriate verbage to describe his body. Meanwhile one of my daughters friends thinks that she has a "WooHoo".
Which is more degrading to a woman? Which is more useful in a conversation with a doctor?
I'll shut up now since I'm just rambling, but suffice to say when my daughter walked in on me playing GTA the other day she admonished me to stop at red lights and not run anyone over.:-)
I have connected to a router with an SSID of private. I didn't know I was connecting to it as I was on a friends notebook and we were at a cafe that advertised wireless. Turns out I was on someone's router living in an apartment near by. Windows simply picked a router and connected. So am I guilty? Point is, the SSID alone can not be held as the absolute "keep out" sign. Something as simple as WEP or a non-broadcast SSID would have kept me out as I was simply relying on Windows autoconfig. Now that's not to say I've never broken WEP, never cloned a MAC, etc. But more often than not it's been as an example to someone as to why they need to be vigilant with their WiFi security, not to steal service. -nB
Your skepticism is mis-placed. There is more than one kind of malware. One kind sends Phishing Spam / Viagra spam / etc. Another performs DDoS attacks. A third acts as a distributed FTP/Fileshare server so that the guilty have a place to hide & share their wares and not have a single point of being shut down by the authorities. Whether this be lists of CC numbers or kiddie porn is immaterial. -nB

In our professionally built system, a Temptronic Atlas series chiller and thermochuck (http://www.temptronic.com/Products/ThermoChuck_Overview.htm) we lost about a pint a month of HFE7100 under heavy load.

As another parent here (who just woke up :), I agree with you completely.
My kids are the only reason I take work seriously, and the main reason for my overall happiness.
