Zoned systems do work really well as long as they are installed and balanced properly and they save a lot of energy. Why would you try and control a system by predicting what its temperature should be when you just have a room sensors which are inexpensive that let you know exactly what the temperature is. The more complicated systems that we design use CO2 sensors to monitor the occupancy and adjust the outside air brought into the system by maintaining a setpoint of 400-1000ppm instead of the code requirement which is independent of actual occupancy. I have also installed systems where the entire building had a keycard system, when the occupant of the office swipes their card, it will change the setpoint in their office from unoccupied to occupied, but that is still done with VAV boxes. You can use dual duct systems where you have a hot deck and a cold deck and mix at the terminal depending on the thermostat setting. Those have better controllability but waste much more energy.
I am a HVAC consulting engineer and I think you are overestimating the complexity of the control systems. The thermal mass, demand, exposure direction, etc are all used in calculating the system and its size, but none of that is really used in controlling the system. What you would typically use is a VAV system [zones with dampers] with its own thermostat. The thermostat in that zone will control the damper position and any reheat if it is provided at that terminal. The main air handler will usually control the cooling or heating coils dependent on the discharge air temperature. You can have an increase in complexity in the system if you are using VFD with your fans based on differential pressure and CO2 sensors in zones to control the outside air intake, but for the most part it is still the relatively simple idea of maintaining a set discharge air temperature and cycling compressors, chillers, boilers or gas.
It is a kernel option called fair group scheduling. If you could recompile your kernel you can change that. I know I had huge issues with this where any disk intensive operation would slow the machine to a halt. That said, the last time I used Ubuntu was years ago and the developers on the forum told me I should never compile my own kernel on Ubuntu, maybe that has changed by now, but it was easy on Gentoo to fix.
The real difference of Slackware is ironic. They don't bastardize their packages with tons of patches. So somehow they are different by not being different? I am now a Gentoo user which is definitely bastardized with tons of patches;) but I grew up with Slackware and still have much sentimental value with its progress. Nice to see it still kicking.
I actually just finished compiling 2.4.0 on my ~amd64 box. I have a dual core amd X2 5200+ and it took a little less than 4 hours. Nothing like the old days when it would take a day or two!
If you are actually compiling OO.o by hand, you do not need java. Just take a look at the Gentoo ebuild and you will see that if the "java" use flag is not set, there is no dependency on java.
Yes I do and guess what, even the best investors lose some money some times. It is not the government's responsibility to cover my ass and they won't, so why should they do it for housing?

Inflation is good because of the irresponsible actions of many that get them into debt? I research a $200 purchase to make sure that I am getting what I want yet these people can't do some research when they are making a purchase as large as a home? I am so damn sick of hearing about these poor ignorant people who were swindled. That is not the case 99% of the time, they got greedy and tried to buy more house than they could afford. Sorry but I don't see how it is my responsibility to pay for the irresponsibility of others. Where is my government check for all of the money I've lost in the market because of this mess???
Microsoft's current net assets are $22 billion, that is half of what the Yahoo deal would have cost. They are offering stock options to Yahoo to cover the rest I believe.
The employees hide in the womans basement for the "surprise." When she gets home she starts calling for her dog, which the employees carefully took downstairs with them so it wouldn't make any noise. Then the secretary, calling for the dog, walks into the basement naked except for the peanut butter strategically spread on her honeypot.
Yes cast iron is quieter simply due to the density of it. A lot of places still require cast iron for the main building sewer since it does last basically forever. Generally they are hubless pipe & fittings or hub and spigot with neoprene sleeves. Lead and oakum is remarkably more time consuming compared to other methods. You can't speak of lead and oakum because unless the building was built prior to 1950 or in Chicago, you won't find it.
I've never concerned myself with noise spec'ing PVC since it is usually concealed in walls or ceilings. You do need to worry about sound with storm water piping though and we call for that to be insulated.
If you are familiar with university buildings they are generally a different beast than your average commercial or industrial building. They have their own specifications that they follow and cost is not always a priority.
Yea, now do you see my perspective. The Chicago Building Code is written specifically for unions, we are the only town that I know of that still uses cast iron with lead and oakum for waste piping. PVC wouldn't take nearly the amount of time to install.
I am not bitter, just stating fact. There is no way I could walk high steel or be happy wrist deep in a sewage pipe. Thats the trade-off I guess. The iron workers I know all make well over 100k a year, but they are always dead tired and have to work 6-10's a week. Plus I am in Chicago, union wages are not the same anywhere, and I believe that it is either the highest paid or up there with New York as far as wages are concerned. Even the construction flaggers on the highway are making $35 a hour.
I rather enjoy my job as well, I design mechanical and plumbing systems in anything from condo's to hospitals and LEED AP certified, have an EI license and eligible to take the PE test this year. I am not some flunkie that barely made it through school, as insinuated in previous posts, I had a 3.5GPA. I have a few gold certified LEED buildings under my design and another going through commissioning as we speak.
I am a consultant and do work more than 40 a week in most weeks. I do fairly well and not starving by any means. I guess my reaction is just to the notion that you have to go to school to make a decent wage, nope, you just have to work hard. I also was referring to unskilled laborer's, knock this wall down, move this pipe here types still get $27-$33/hour around here. I also understand that there isn't much room for growth, labor rates for an electrician with 5 years experience is the same as the guy with 20 assuming he is still doing journeyman work, and supervisors really don't get that much more, last time I checked its only a $1 or $2 an hour difference.
I provided a link with all of the wage rates in my previous post. No union worker makes less than I believe $24/hour + benefits. Most skilled union workers e.g. plumbers or electricians make about $40/hour. This is in Cook County Illinois, which if you are unfamiliar with the area, is where Chicago is located. Unions own the city, but still, they make better money than pretty much anyone with an undergraduate degree and less than 10 years of experience. I make significantly more than $45k, but still less than the $85k I would be making now if I became an electrician or plumber, and they get paid while they are apprentices, not paying out $100,000 for their education.
Union labors here in Chicago make over $33/hour. That is a base salary of $68,640 which does not include pension, sick time or medical, thats another $10-15 an hour or so. You are now looking around $100k a year. Now add in overtime pay.
My compensation is right in line with my field and experience and right along the same lines as my colleagues, none of us make even $80k. My point is that those "ditch diggers" although frowned upon apparently, probably make more that most do. How many college graduates do you know that start off earning much higher than $50,000?
I wish I was a "ditch digger." I have an engineering degree, which apparently entitles me to such things as straight no time-and-a-half overtime and less wage than any unskilled union laborer.
Would I be happy digging ditches, probably not, but it does get a little daunting when everyone I know who went to college makes less than those who didn't.
Actually its people like you that drive health care costs up, since you have no insurance, get it a car wreck and spend a couple of days in the hospital. You don't have the means to cover your costs, so now its passed on the me the lowly responsible middle class citizen. Thanks.
Yes many more people own homes than tech stocks, yet many people are also long in the housing market. Unless the market continues on a downtrend for say oh another five years and it wont, this is nothing but a blip. Overall home prices are still up around 20 percent from five or so years ago, they just aren't increasing at a 50 percent per year rate, which everyone knew couldn't continue. There are three groups really affected by this: those who bought a home way outside of their budget via a bad ARM; those who were speculators; those who were forced to move in the middle of this, e.g. job relocation. It really is not as bad as everyone is making it out to be. Six months to a year and it will begin to turn around. Builders over saturated the market, simple supply and demand.
You left out the word "housing" in your alarmist "most severe recession since the Great Depression" comment. All housing is doing is recorrecting. It doesn't matter much when housing, which was artificially rising because of cheap money, is falling back to reality. This is much less of a bubble bursting than the dot com bubble and the recession we were facing 7 years ago. The subprime mortgages account for about half of one percent of total mortgages. Housing accounts for about five percent of our total economy. This "most severe recession since the Great Depression" accounts for at most one tenth of one percent of our economy.
Wouldn't making a backup and storing it elsewhere be considered piracy??? I mean if you have two copies of the same song, my God, two people could listen to that song when only one person paid for it, the Horror!!!
All of this doesn't matter though. I know it is the vendor's fault for not writing their software correctly or providing a compatible version, but again that doesn't matter. To the end user, if it doesn't work, it doesn't work, doesn't matter whose fault it is. All the claims of peripherals not working or video card drivers is not linux's fault since it is the third party responsible for not providing drivers, but the end user doesn't care why it doesn't work, they only care that it doesn't work.
