It could be that it really takes that much longer. For example large cache folders from mail clients like thunderbird or outlook express, and from web browsers, may make this take very long (????) Or you could be looking at cycles somehow. Can you build in code somehow to signal the existing threads that they should pr... |

Um… you're walking the filesystem and putting every file in the tree into the queue, and then for each file in the queue you're walking the entire tree again and pushing every file in that tree into the queue. All this pointless repetition is going to take a very, very long time for even a modest subtree. – abarnert J... |
Actually, hold on a sec… you're using target without ever defining it. So, unless your C: drive is completely empty, this is obviously not the code you're running, because this code will throw a NameError and quit immediately. – abarnert Jul 10 '12 at 1:17 |
can you try and run in a shallower and overseeable subdirectory, instead of your hard disk's root? – Andre Blum Jul 10 '12 at 2:09 |

[ First, of course, I had to make some trivial changes to make this code 'compile'] |
The good news is: it just works as you think it should work. Well done. The bad news is: it doesn't work as fast as you had expected. |
On my machine, running it on my home directory alone already takes approx 10 minutes: |
[andre@hp ~]$ time python |
what you wanna get |
... results removed ... |
real 9m39.083s |
user 0m30.368s |
sys 0m22.664s |
[andre@hp ~]$ |
The question is whether implementing this in processes and threads is a good idea. I think not. Chances are the performance suffers from this massive multithreading. |

I finally make it work with coroutine. make a connection with coroutine instead of using "done" with Queue.put, but it just 2 seconds faster:( I agree with you. it was not a good idea. thank you! – from __future__ Jul 11 '12 at 6:23 |

Floor Speech |
Location: Washington, DC |
Mr. WATT. I move to strike the last word. |
The Acting CHAIR. The gentleman from North Carolina is recognized for 5 minutes. |
Mr. WATT. Mr. Chairman, I don't come to the floor very often anymore to debate. I have kind of changed my pattern. Eighteen years ago, 19 years ago, when I saw egregious things, I would be right here in the heart of the debate, ranting and raving, some people would say. |
When my colleagues and sometimes my constituents now ask me, Have you lost your passion, I tell them that there are some reasons that I don't come to the floor anymore. One is that I find that most of the time, my colleagues on the opposite side are tone deaf. They are not really listening to what anybody is saying to ... |
They don't share my values, and they don't really care about this debate that we had, 3 hours of talking about women, infants, and children going hungry. They really don't much care about that, I say to my constituents. And, third, they just make up stuff. You know, they have this--you know, if we repeat it enough, it'... |
The Acting CHAIR. The gentleman will suspend. |
For what purpose does the gentleman from Nebraska rise? |
Mr. FORTENBERRY. The gentleman has accused our side of the aisle of lying. Is that a cause for having his words taken down? |
The Acting CHAIR. The Chair construes that as a demand that words be taken down. All Members will suspend. The gentleman will take his seat. |
The Clerk will report the words. |
[Time: 20:20] |
Mr. WATT. Mr. Chairman, in the interest of time, some people have said that I called somebody a liar and, obviously, that would be in violation of the rules. I am aware of that. So if I did, I ask unanimous consent that those words be removed from the RECORD. |
The Acting CHAIR. Is there objection to the request of the gentleman from North Carolina? |
There was no objection. |
The Acting CHAIR. The gentleman from North Carolina may proceed in order. |
Mr. WATT. Can the Chair tell me how much time remains in my 5 minutes? |
The Acting Chair. The gentleman from North Carolina has 3 minutes remaining of his 5 minutes. |
Mr. WATT. All right. Well, let me try to pick up essentially where I was without offending anybody else. |
There's some conveniently forgotten items that I think we need to be reminded of. Number 1, that it was President Bush who requested the government bailouts. That occurred on his watch. It was President Bush that was responsible for the tax cuts for the rich that got us out of surpluses as far as the eye could see and ... |
It also resulted in a tremendous economic down |
turn that resulted in more people needing food stamps and the benefit of the WIC program. So these two things are really not disconnected from each other, the 3 hours of debate that we had previously and the debate on whether we are going to adequately fund the CFTC, which has been given authority under the Dodd-Frank ... |
So this whole process of being in denial about this and ignoring the facts is something that I think we should not countenance on this floor. We need the CFTC to regulate derivatives and speculation. And to the extent that we cut the staff and the funding of the CFTC, we could be replicating exactly what led President ... |
So, that's what this debate is all about. I think it's terrible that we are cutting funds under this bill for women, infants, and children, the most vulnerable in our society. But it's even more terrible that we are going to run the risk of allowing the same kind of rampant speculation, unregulated, to get us back into... |
Now, this is not rocket science. It's all just connected to each other. And my colleagues can deny it all they want. They can say that this is about drilling for oil in the United States. That's not what it's about. All of the science I've seen says there's more supply of oil now than there is demand, and if we were op... |
We need to regulate the CFTC. We need to have them regulating derivatives and speculation. |

Phil Shaw, victim's brother |
Phillip Shaw was born on January 7, 1975, in Taylor, Mississippi, the eldest of two children born to Jane and Chad Shaw. He was seven when his little brother Jerry was born. |
The age difference between the boys meant Phil spent a lot of time watching over his brother. He tried to teach Jerry the importance of honesty and integrity, but as the boys got older, Jerry increasingly resisted Phil's guidance. |
Their parents held Phil responsible whenever young Jerry acted out, which Phil considered unfair, especially since he couldn't find any way to get Jerry behave, no matter how much he tried. |
Other than his inability to control Jerry, Phil excelled in everything he did. He made top grades and had a lot of friends. |
When Phil graduated from high school, he wanted to go to college but there wasn't enough money so he got a job as a busser at Taylor Grocery & Restaurant. He put every penny he could spare in a savings account that he planned to use one day to pay for college. |
In 1994, his parents went to Memphis, Tennessee for the weekend to celebrate their 20th anniversary. Tragically, they were murdered during that trip, and the case remains unsolved to this day. |
Phil became Jerry's guardian and used his share of their parents' large insurance policy and sizable savings account to support the smaller, sadder version of his family and to pay for his classes at Ole Miss. |
Phil invested some of the insurance money, and when he graduated, he still had a large bank account. He leveraged that nest egg to build his own tax firm, which became a very successful business. |
When Jerry dropped out of high school and proceeded to squander his inheritance like the proverbial prodigal son, Phil avoided him. |
After that, the only time he heard from Jerry was when he came asking for money because he'd gotten himself into yet another financial jam. Phil always refused to lend him a dime and told him to get a job if he needed money. |
Phil is single and lives alone. By his own account, he and Jerry hadn't seen each other for years at the time of Jerry's death. |

• Phil wasn't much of a brother to Jerry. It appears that Jerry was on his own totally when he dropped out of school. He was probably 16 years old. Who knows what kind of life he had besides the gambling. |

Boiler Room Safety |
Large industrial and commercial facilities often have dedicated boiler rooms that house boilers, water pumps, heating, ventilating and air conditioning (HVAC) equipment, and other mechanical equipment required to run a facility. The heated water or fluid used in boilers can be used in a variety of processes or heating ... |
Gas Detection |
Hazardous gases found in boiler rooms include: |
• Combustible Gases such as Methane |
• Carbon Monoxide |
Combustible gas leaks rapidly disperse throughout a boiler room, creating a hazard for any worker, who can act as an ignition source, by walking into the room. Fixed point combustible gas sensor modules are used to monitor boiler fronts and associated natural gas supply lines. The gas sensor modules are connected to co... |
In addition, fixed point toxic gas sensors are used to monitor for CO leaks in boiler rooms. If not detected, the buildup of CO can pose a threat to any worker walking into the room. The sensor modules can be connected to the same controllers used for combustible gas, creating a complete hazard detection system. |
Personal gas monitors are generally not appropriate for boiler room applications because they cannot detect buildup of combustible and toxic gases in a non-occupied area. |
Automation and Integration Strategies |
A gas detection system usually incorporates a controller that can drive various alarming devices such as strobes and horns to indicate hazard. However, as boiler rooms tend to not be accessed frequently, facility managers often need a remote monitoring solution as well. It is common for facility managers to connect the... |
Codes and Regulations |
Various national and international codes pertain to the safe manufacturing and placement of boilers. In the United States, manufactured boilers and the rooms in which they reside are designed to comply with one or more of the codes written by the American Society of Mechanical Engineers (ASME). Other approval bodies, s... |
Major codes governing boiler rooms include: |
Products for Boiler Room Safety |
Boiler rooms require a gas and fire detection system that includes gas and fire detection modules, a method to communicate to a controller, an ability to collect large amounts of data for subsequent analysis and flexible alarm handling with a method for communicating data to higher-level systems. |
