Water boils at 95C i denver. Precipitation that falls when its less than 4 deg C tends to be frozen as well. That should like about 5% slop based on your definitions.
If your stuck in a poor lab in a third world country, its much easier to calibrate a Fahrenheit thermometer than a Celsius one since you need to compensate for air pressure and have pure water for Celsius. For example Celsius's zero point differs almost a degree based on air pressure and boiling can differ by 30% if your high on a mountain. Polluted salt saturated ice water is less than.1% at all altitudes and a healthy dogs rear tends to be the same as well. Fahrenheit was based on better science than the Celsius scale (which used to use 100 for freezing and 0 for boiling).
Burning plants tends to make about 1 ton of CO2 per ton of plant. It turns out that if you burn the 35-50 tons of fuel you end up reducing the temperature of the fire by a significant amount so more trees survive. Many areas also are subject to desertification processes which means due to a lack of future water, there will never be as many tons of trees so what used to be a CO2 sink, no longer is as large. The numbers I remember for a forest like the one near Marryville will be about 15,000 tons of trees per ha while forests on the north side of Mt Macedon are closer to 5,000 and drop to about 1,500 tons per ha in areas adjacent to the deserts. If those numbers are accurate, then the failure to burn 50 tons of fuel you quoted may have resulted in a permeant loss of maybe 10,000 tons of CO2/ha in the worst burned areas near Flowerdale.
Hopefully someone will post accurate numbers since I'm sure the ones I remember are mixing up metric and imperial systems worse than a NASA space probe.
Some of the ones that are still around were installed as part of a warning system that dates back to WWII. They work in other parts of the world, and they aren't that expensive either.
The glue is the problem most of the time. That has been the case since the 1950s and while there have been lots of attempts to fix it, I'm not sure the new stuff is progresses since it just pushes around the problem.
Have them build a lumen meter for measuring light bulbs. Its the sort of thing that each year and add to or redesign since it seems simple to get initial results but the problems go much deeper.
The poster child for the "Broken Internet" is the email protocol SMTP. There are other options. You can get X.400/X.500 based email and all you need to do is download Isode and install it... and get all the right certificates and find someone who is willing to talk to you. The US Government is required to migrate to X.400 based email sometime based on their GOSSIP standard. Many commercial mail platforms started out with X.400 and converted but you can see their history with the x.500 style directory services. There are lots of OSI standards that could replace the current TCP/IP stuff yet it appears that no one cares.
All measuring devices have limits and I've found most power meters tend to get very sloppy on their lower ends and that can often be in the range of 10 w. If the power factor is nasty (as it often is with low power loads), the meter will give huge errors. What seems to work best is find 10 of your worst wall warts and plug them all in one power strip and measure them that way. Pull one and and see how the rating drops. You can also use a 60w incandescent bulb as a base load since they are very consistent and have a pf of 1.00.
If you have an older style wheel meter, its only compensation for power factor (if any) will be lead/lag. Switching supplies have other power factor issues that newer digital meters account for and bill you for.
I have a bad habit if measuring claims made by manufactures and it appears that lots of them must have access to those invisible pink unicorns since their claims are way off. I find that CFLs are the worst offenders and often to take up to about 55% more power than they claim and while I can't measure a lumen from a non-consistent point source (I'm not even sure how it should be done), I can measure average light output in LUX after a bulb is 1000 hours old and I have yet to be impressed with the honesty on the product boxes.
I have found that larger companies with a strong European market are doing much better with their standby power. My imac and Nokia chargers take so little power when the device is fully charged that is less than the error range of the instruments I use.
Some of us older guys don't care. We have Solaris (9 not that 10 crud) installs with 4 package that haven't needed to be patched in years and we don't buy into the latest $FOO which needs 18,000 versions to fix. We solve problems in a lean mean way. If your "fancy code" relies on 20,000 other people's code (90% of which can not be tested), your job outlook is much worse.
But its right. I'm guessing less than about 10% of programmers have what it takes to do their job right and less than 1% of people in general have what it takes. Sysadmins are even rarer since they need to organize but live in chaos.
All sysadmins are IT janitors. The ones who understand that have a much better chance of keeping their job when things go bad. Maybe we should call it IT sanitation engineering?
Just make sure you crane operator has very good depth of field. The trick for them is to be able to judge 6 inches from 150 feet way. And no your not alone. I know many hackers that have decided that its better earnings away from the IT circus.
The phonetic alphabet can be a great time server... "Ok you need to find the server tawks in the rack. that is T-A-W-K-S as in Tsunami Are Why Knot Sea."
My home servers (that live in data centers?) are called things on a "0" theme. Knot, Naught, Not, Knotty, 0.
For work I'm thinking about pc### where ### is the phone extension and dhcp will hand out 192.186.1.177 to the person at extension 177. It should make it easier to locate problem machines.
Japan and Korea started out with PON which used expensive optical tricks but saved having to have active repeaters and switches in odd places far from the exchanges. Now that optical swtiches are getting very cheap, its cheaper to put a switch in a box somewhere and run a direct fiber pair from each home to that box. That has the advantage that you can do gigabit today and fast later.
Grass doesn't do web well since it was it predates the web. When I quit working on it in 1987 it was still mostly FORTRAN but at that time lots of the C interface code was written by me. If you don't like what I did, feel free to rewrite it.
A car is much more than just a transport tool. It can be a mobile office as well as providing isolation, control, projects images of power and others. After all guys still buy cars that appear fast to impress girls. A modern cubical (and its associated hallways) is smaller than the space need by parking space (and its associated lanes)
And how do you compensate for the fact that light is not evenly distributed over the area? I guess the proper solution is to takes lots of readings than integrate over a steradian. But that still leaves the question of which steradian do I use? Most CFLs range from full intensity to less than 1/3 intensity depending on which angle you look at.
Who is trying games with the truth? The 3 mg is a long range target and they hope to get under an average of 5 mg this year to keep Europe happy. That patent you talk about is an extension to the slow start technology used decades ago not what is in most modern bulbs. CFLs go bad because either their ballast go bad or their mercury is no longer in an excitable state which happens when it bonds with other stuff in the tube so it doesn't matter what alloy was put in the thing at the factory if it breaks down and bonds with the phosphorus coating stabilizers.
The key word is "should". I have about 20 of the cheapest fixtures the builder could find that were wired into one switch but I had a cord put on one so I could plug it into my UPS. My Kill-A-Watt told me 193 W. As far as which is brighter, I don't care about lumens since I can't measure them but I can measure lux and where I need to work when the power is out, a 100W incandescent will provide more light.
The box says 800 lumens. How can you verify that claim? I have a light meter and power meter and a 4xU tube type CLF will produce 1/3 the light on its end as its brightest spot yet its brightest spot seems to be the reference point that someone used to determine its "lumens". The ISO standard also seems to have a test as if all light bulbs are point sources.
The coal plaint isn't a short drive up the water table from you like your local land fill may be. How much lead is in the glass in the CFL? How many other toxic things are in it as well?

How do you define a mess? I tend to define it as "Is it done?" When the answer is "no", then the next question is "will it ever get done?"

Where does this 5 mg come from? I know its the number the EPA pulled from somewhere but others who
have measured such things don't agree.
