  1. It used to work for me on Mountain View To Partially Replace Google Wi-Fi · · Score: 1

    One downside of free WiFi is that there is no one to call when it stops working. I live in Mountain View, and when Google WiFi first came out it was good enough that I dropped my DSL. I was very happy with it for about a year, but then it got intermittent at my house, working well on some days and not at all on others. After a few more months it wouldn't work at all from early evening until after midnight, presumably because everyone else was also trying to use it at that time. After that I switched to Comcast - they are overpriced and a pain to deal with, but at least when I call to complain that my service has failed they manage to fix it eventually.

    As a side note, it always worked well a few hundred feet from my house, so I assume that the back end was working OK.

  2. HP profit sharing was 12% of pre-tax profits. on Christmas Bonuses? · · Score: 1

    Back when Hewlett Packard was one of the greatest companies in the world they gave 12% of pre-tax profits as 'Profit Sharing.' Profit sharing was paid out twice per year. Almost everyone in the company was included. In good years each profit sharing check would be close to one months pay, in bad years they would be much smaller.

    HP no longer gives the 12%. Agilent (a spin off of HP) doesn't have any profit to share, and if they did they would give far less than 12% of pre-tax profits. They both have changed to formulas based on factors like return on assets and revenue growth, with an explicit goal of sharing less of the profit.

    Profit sharing had the obvious motivational benefits, but it also made employees feel that they were part of a great company and not simply cogs in a machine. This was part of what made HP so successful.

    You can debate whether HP was so successful that it could afford to give 12%, or was HP so successful because it gave 12%. My belief is that profit sharing was one of many things that made HP great. By itself it neither makes nor breaks the company, but it was one important factor in HP's former success.

  3. Re:But the precedent isn't on AOL Hacks Subscribers' Computers · · Score: 5, Insightful

    I think jaredmauch hits the nail on the head when he says "You're not talking about your 'Average' ISP." AOL is very paternalistic, giving its customers a nice, safe, easy environment that you or I might find infuriating but that some people really like. Those people who want 'somebody who knows computers' to manage their 'online experience' are the same people who want 'someone who knows computers' to manage their PC.

    I think AOL may be accidentally backing themselves into a good business model. You buy the PC and sign up for AOL, and they take care of all of the rest of the technical stuff for you. I won't be signing up anytime soon, but I bet a lot of people would love the service.

  5. Re:Exactly correct, need hydrogen on (Solar) Power to the Masses · · Score: 1

    You are right, they do know how to handle hydrogen industrially, and they can do it very well. The mechanics, plumbers, technicians etc who work with hydrogen are all very skilled and know all of the necessary tricks.

    I am sure that if you were piping hydrogen from a big industrial facility to a big commercial power plant, with all of the infastructure that goes with big industrial chemical plants, it would be relatively safe and easy. The part I wonder about is sending it from small, decentralized generation facilities to small, decentralized fuel cells. With lots of small operations spread all over, it would be difficult to maintain the infrastructure and experience needed to handle hydrogen safely and efficiently.

    Of course, I guess the same thing could have been said about electricity 100 years ago.

    Actual hydrogen pipelines break and spill just like every other kind of pipeline ever built.
    Which is why we don't use, say, oil pipelines. :)

    Actually, hydrogen pipelines are the most leak-prone plumbing I have ever worked with. H2 is a small molecule, it will slip through the tiniest imperfections in your plumbing. I was working at lab scale, so we could be exceptionally careful and attentive to detail, and we still had problems.

    The same plumbing techniques that worked perfectly with nitrogen or helium were barely acceptable for hydrogen. Valves and other fittings had to be in perfect condition or there was no chance that they would work. We could make it work, but it took a lot of effort and a lot of testing and rework. This was mainly with 1/4 and 1/2 inch diameter tubing, bigger lines are even harder to get leak tight.

  7. Consider Aluminum Structural Framing on Building a Stained Glass Computer Case? · · Score: 1

    You might consider the aluminum structural framing used in a lot of custom industrial equipment. This is basically bolt-together aluminum channel. It is fairly easy to put together, makes a very nice rigid frame, is easy to attach brackets to, can be cut with simple hand tools, and some brands look pretty good. A lot of small to mid-sized custom industrial equipment is in boxes built with these frames - often with rectangular tubing forming the edges of a box and glass or PVC sheets forming the face of the box. Using stained glass in place of the window glass or PVC seems a natural fit.

    The problem would be that this stuff is priced for industrial users. To get an idea of what is available and what it costs look up structural framing at McMaster Carr. McMaster Carr is a full-priced industrial supply company, so nothing there is cheap, but this type of stuff is hard to get cheap. If you can find somebody who is buying this stuff in bulk they might be willing to sell you some of their scrap pieces. The type of company that might have this stuff would be automation houses or custom machine builders.

  8. Re:I have a similar problem.. on PC Cases for High Dust Enviornments? · · Score: 1

    If you are in metal recycling plants, you probably have compressed air available. If the compressed air is relatively clean and oil free, you can do like a lot of industrial electronics cabinets do and feed compressed air into the cabinet. This cools the cabinet and also keeps the cabinet at positive pressure to keep other junk out.

    The only place I have used this scheme is in a large factory with automatic hoists, large motors, and other noise sources. In that environment the noise is not noticeable, but in a home or office it might be intolerably loud.

    The easiest way to do this is probably to leave the exhaust fans where they are now, leave all the existing inlets open, add a 1/4 inch tubing inlet with a valve to introduce the air, and slowly turn the valve up until the case pressure is just slightly positive with the exhaust fans running. (Measure the case pressure by finding an opening that is not near an exhaust fan and hold a piece of paper against the opening - when the paper starts to flutter you are just barely at positive pressure.)

    To reduce the air used, and also reduce the noise, you can plug up all of the air inlets so that there is very little air exiting except at the exhaust fans. The downside of this is that if the compressed air goes off the PC will overheat since there is not enough air coming in. In industrial settings we usually had a pressure sensor and shut things down when the air pressure dropped for more than a minute or so, but this may not be appropriate for a PC.

    If you wanted to get really extreme, you could water cool the cpu to an external heat exchanger, cooling the inside of the case in the process. Eliminate the exhaust fans, add in some circulating fans, plug most of the outlets, and set the air flow to keep the case pressure slightly positive. Of course, by the time you did all this you would essentially have an industrial PC and it would cost as much as an industrial PC.

    One thing to watch out for if you do this, maintence people sometimes add oilers to airlines that previously had nice clean air (usually because they assume that the line is only being used to run pneumatic tools and they decide that it will be easier to maintain one big oiler on the supply line instead of lots of small oilers at each tool.) I can tell you from sad experience that if this happens you will have a thin film of oil on every surface inside the case and that it takes many hours to clean this up.

  9. For Some it Does Not Matter, But for Many it Does on Success Despite College Rejection · · Score: 1

    It doesn't surprise me that a few extremely successful people like Spielberg succeed brilliantly despite a less prestigious and possibly less rigorous education. What would surprise me is to find that the typical student applying to elite schools would not have a far more successful career after graduating from an elite school like Harvard than after graduating from a 'lesser' college like Cal State Long Beach.

    To drastically oversimplify the situation, I have noticed that there are three broad groups of people in any almost every work or school situation:

    1. Inherently Successful People: People who will succeed brilliantly no matter what obstacles they face. Most of us like to think of ourselves as members of this group, but few of us really are.
    2. Ordinary People: People, often very smart, capable, and hard working, who given a few lucky breaks or good opportunities can capitalize on them to build a good career. These are the vast majority of the people I have known in school and at work.
    3. Screw-Ups: Screw ups are unable to do a good job, no matter what opportunities they are given and no matter how many breaks they receive. Fortunately few people are inherently screw ups, but there are always a few of them in any large group.
    An Ivy League or Stanford education, a rich well connected family, friends in high places, and all of the other traditional predictors of success are nice but unnecessary bonuses for the inherently sucessful, a huge help to the vast majority of ordinary people, and very little help to the screw-ups.

    I used to have a job where I was never at my desk - I was either in meetings or on the production floor or working on a piece of equipment .... I would often have to find info, schedule meetings, call people, ... when I was nowhere near my desk. I used an hp200LX (an ancient DOS based PDA) that was very good, then 'upgraded' to a Handspring when the powers that be demanded that I keep my calendar up to date in Outlook.

    I used the PDA a lot in those days, both for work and for personal use. I had all of my social and weekend activities scheduled in, I had all of my friends and families contact information, birthdays, ... entered in. I even had all of the recipes I like to cook programmed in (it is amazing how nice it is to be able to decide you want to cook something and just stop by the store to pick up the ingredients without having to go home and look up the recipe first.) I was completely addicted to the PDA and couldn't imagine how I had survived without one. I was sure that even if I didn't need one for work I would continue to use one.

    I used the PDA almost daily for about 5 years, and then I changed jobs. I do a lot more programming now, and spend a lot of time at my desk. Meetings are either routine and planned long in advance or else impromptu 'are you available now ?' meetings. I slowly started to use the PDA less and less. It is now sitting in a drawer at home and hasn't been used in over a year. It turns out that my old job's requirement that I be able to schedule meetings at any time and keep my Outlook calendar up to date was in effect paying the overhead of carrying the PDA around and constantly entering information.

    Once those requirement were gone, it turned out that all of the 'essential' additional uses I found for it are not worth the overhead of carrying the thing around.

    Representing constituents is one of a legislators most important responsibilities, but it is not their only responsibility. The constitution says that they "shall be bound by Oath or Affirmation to support this constitution" and from the senate's "How the Senate Works" page the current oath is:
    I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God.
    A legislator has to represent constituents, represent the whole country, act consistently with personal moral/religious beliefs, and get re-elected. People who can reconcile all of this may at times appear to be slimey and unprincipled, but that is what is needed to make the compromises that allow us to work as a society.

    Getting back to the topic of letters to a legislator, the article makes it sound like most legislators are at least trying to strike a balance - a staffer will read the email if it is from a constituent or if it is about an area the legislator is active in. This is probably a reasonable compromise.

The standing joke is to compute our duty cycle while in class, i.e. the fraction of the time that we actually need to pay attention while in class. In college I was often at over 100%, I could not think quickly enough to keep up with the lecture and had to come back to it later to think it through properly. At work related classes it is rare to be any higher than 20%.

    They usually teach these classes based on what they call the 'Adult Learning Model,' which seems to basically mean they make sure that each student must completely understand each piece of information before moving on to the next. It also seems to mean that the thought process must be simplified to the point that a trainer can follow it. This seems to work well for simple fact based courses like 'How to Fill Out Your On-Line Timecard, works adequately for slightly more complex topics like 'How to Track Your Order Using Our New ERP System', and is a complete failure for complex subjects.

    There have been a few pleasant exceptions over the years, classes were I actually learned a lot about a difficult subject, but these were usually outside the usual training process and were taught by people who love the subject material.

    I think a lot of it comes down to the difference between training and education. The usual corporate training process is good for teaching us how to follow procedure, but not very good at teaching anything that requires independent thought.

You may have to search a lot harder to find a decent job like this, and it will probably pay less than a CS job, but it might get you into something you find interesting.

    Another option to consider is grad school in a field that interests you. This is what I did. Some grad schools are open to people making a big switch in fields, while others are not, so you will have to look around a bit to find one. You will probably have to take a lot of undergrad classes in your new field.
