FreeBSD 7.0

BSD is the best kept secret in the world of desktop operating systems. And by "secret," I mean not the least bit secret, completely out in the open, freely available to all, and entirely open source. Talk about hiding in plain sight! So what is it?

Let's begin with a little history: UNIX is a multi-user multitasking operating system developed in 1969 by AT&T employees at Bell Labs. The name is reference to an even earlier OS Multics, so it's ironic that the copyrighted name UNIX® has been so jealously guarded for all these years. Almost as soon as UNIX appeared, various organizations began to create their own software around the same general framework, most notably UC Berkeley with their Berkeley Standard Distribution -- BSD for short.

With so many versions of *nix floating around, it was inevitable that the POSIX (Portable Operating System Interface) API would be formulated to ensure interoperability. So all the flavors of BSD, Linux, SunOS, Irix, HP/UX, etc. can now be called simply "POSIX-compliant UNIX-like Operating Systems" (or just *NIX). All this development occurred in the realm of big iron, since Intel's first multi-tasking CPU (80386) didn't arrive until 1986, followed by POSIX in 1988.

The Regents of the University of California released the BSD code into the public domain in 1990, and the first x86 architecture port of BSD -- 386BSD followed in 1992. So, if there's been a perfectly serviceable network-ready clone PC operating system freely available since well before Windows 95, why are so few people using (or even aware) of it?

One reason is that it's free. A lot of people automatically distrust freeware. There is also no particular incentive to promote or advertise FreeBSD and its variants, although some enthusiasts (like me) do what they can in terms of advocacy. Then there is the question of suitability for a given task. *NIX is much better adapted to network server applications than to stand-alone desktop use. Finally, Windows and *NIX are very different in their general philosophy.

Windows requires relatively little expertise to successfully install and operate. Everything is done automagically by wizards. BSD is vastly more configurable, but that versatility comes at a price: You need answers where you didn't even know there were questions. That isn't an insurmountable problem -- BSD has some of the most extensive and complete documentation available for any software. Unfortunately, accessing that information can be a bit overwhelming -- like taking a drink from a fire hose.

Here's what to do: the next time you replace a computer (or see one being discarded), use it for your BSD project box. There's no substitute for diving right in and getting your feet wet. If you've already tried this in the past, try again. The 7.0 Release is a big improvement over previous releases in terms of ease of installation and configuration. Don't worry if you can't get everything you could possibly want up and running in an afternoon, that would be an unrealistic expectation. Just fiddle with it when you can and before long you'll be amazed at what that old "piece of junk" computer can do unencumbered by an operating system so "advanced" that you need a new computer for every new OS version.

Now I'm not even going to attempt to tell you how to use BSD in you particular circumstances, or even which flavor is best for you, but I will point you to some significant resources:

  • The FreeBSD Handbook (volume I) This users manual will take you step by step through the process of installing FreeBSD on a PC-clone and setting up a graphic user interface, which should be a more comfortable environment if you are accustomed to Windows.
  • The FreeBSD Handbook (volume II) This administrators guide focusses on network server tasks.

Like the OS itself, these resources are available online, but sometimes a hard-copy edition is much handier. Even if you are installing a version of BSD other than FreeBSD, this documentation will be helpful.

You may want to get installation CDs, but if you have broadband internet, I recommend that you try installing from an FTP server first. It's surprisingly easy and (sort of) fast. All you need to do is follow directions to prepare 5 floppy disks, then the rest of the distribution will be downloaded as needed during the installation process. (Try that with Microsoft!)

After you have installed BSD you will have access to the manual pages accessed by the command "man <command>". Start with "man man" to learn more about the man command itself, and since you probably can't read fast enough to absorb the whole page as it flashes by use the pipe (|) character to redirect output to "more," a simple utility that displays one page at a time. So you'll type "man man | more" (without the quotes) then press enter.

Like Perl, *NIX make easy things easy and hard thing possible. Enjoy.

Obama Cabinet Members

President-elect Obama announced the last of this cabinet-level nominations Friday. Having run on a platform that promised to unite America, the list is notable for its ethnic, gender, and ideological diversity. It is said that compromise is a solution that pleases noone, and while these cabinet picks have already been widely criticized by both the left and the right, their expertise has been little disputed.

After eight years of Karl Rove's divisive politics of the perpetual campaign, it is refreshing to see glimmerings of a return to efficacy in public life. Obama has never been the left-wing extremist that Republican spin-doctors have portrayed him as, and it appears that he intends to make good his promise to be a president for all America -- if the "loyal opposition" gives him half a chance.

Obama says he wants to have the benefit of diverse opinions and vigorous debate before setting policy and Doris Kearns Goodwin's quotable Lincoln biography -- Team of Rivals has often been referred to in this context. Reportedly, John McCain responded: "Senator, I served with Abe Lincoln. I knew Abe Lincoln. Abe Lincoln was a friend of mine. Senator, you're no Abe Lincoln." -- but I think that's just a joke.

Herewith are brief descriptions of the prospective new cabinet members, subject to Senate confirmation:

Secretary of StateHillary Clinton
Secretary of the TreasuryTimothy Geithner
Secretary of DefenseRobert Gates
Attorney GeneralEric Holder
Secretary of the InteriorKen Salazar
Secretary of AgricultureTom Vilsack
Secretary of CommerceBill Richardson
Secretary of LaborHilda Solis
Secretary of Health and Human ServicesTom Daschle
Secretary of Housing and Urban DevelopmentShaun Donovan
Secretary of TransportationRay LaHood
Secretary of EnergySteven Chu
Secretary of EducationArne Duncan
Secretary of Veterans AffairsEric Shinseki
Secretary of Homeland SecurityJanet Napolitano

Steven Chu (Energy)

      Chu is a Nobel Laureate in physics and the director of the Lawrence Berkeley National Laboratory where he has emphasized technology to reduce greenhouse emissions. He helped to establish Stanford's Bio-X program, which encourages a multi-disciplinary team approach to problems frequently lacking in scientific research. He has also fostered cooperation between academia and industry, brokering a deal between the Berkeley Labs, the University of Illionois, and BP. Although controversial, this consortium is advancing scientific research in an environment where alternative energy funding has been conspicuously lacking.
 

Hillary Clinton (State)

     Former first lady and Democratic primary contender, Hillary Clinton is on of the most recognizable names in American politics. During her college years, she supported Barry Goldwater in 1964, but by 1972 had become transformed into a supporter of Eugene McCarthy. It is therefore ironic that her refusal to characterize her vote on the Iraq War Resolution as a mistake arguably lost her the Democratic nomination. During her distinguished career as a lawyer, first lady, bestselling author, and senator, she has established herself as a strong advocate for human rights -- a reputation that should serve her well as Secretary of State. Her books include: It Takes a Village, An Invitation to the White House: At Home with History, and Living History.

Tom Daschle (Health and Human Services)

     Since his demonization by the Bush administration despite his decidely moderate voting record and his narrow defeat in the 2006 senate race, respected and popular Senate Minority Leader Tom Daschle has focussed on health care. His book Critical: What We Can Do About the Health-Care Crisis is a mixture of sound public policy and political pragmatism that should be required reading for the American voting public. Skyrocketing health-care costs are as great a threat to the economy as the Iraq War and the lack of a coherent energy policy, and we can only wish Daschle well as Secretary of HHS and director of the coming White House Office of Health Reform

Shaun Donovan (Housing and Urban Development)

     At 41, Shaun Donovan is the youngest of the Obama nominees, but he has still assembled an impressive resumé. After completing his degree in public administration at Harvard's John F. Kennedy School of Government and an advanced degree in architecture at the Graduate School of Design, Donovan served as Deputy Assistant Secretary for Multifamily Housing at HUD, and as an acting FHA Commisioner. In 2004 he became the head of the New York City Department of Housing Preservation and Development.
 

Arne Duncan (Education)

     Another youthful Obama cabinet designee, Duncan played basketball at Harvard, where he graduated magna cum laude in sociology. He became director of the Ariel Education Initiative, enhancing children's educational opportunities on Chicago's South Side in 1992. In 1998 he joined the Chicago Public Schools, where he became Deputy Chief of Staff for the Schools CEO in 1999, whom he succeded in 2001.
Read more about Arne Duncan 

Robert Gates (Defense)

     

Gates is probably the best Secretary of Defense one could expect from the ideologically-skewed Bush administration. Even as the impending redefinition of our middle east policy argues against an immediate shake-up of the top-level military command structure, those ranks have simultaneously been purged of those unwilling to endorse the nonsensical Bush Doctrine.

Gates was nominated Director of the CIA in 1987, but withdrew when it became clear that the Senate confirmation would be hampered by his role in the Iran-Contra debacle. Daddy Bush nominated him again in 1991 and he was confirmed. He retired from the CIA in 1993 and during the Clinton years occupied several positions in academia, including president of Texas A&M University.

Gates declined the junior Bush's nomination as Secretary of Homeland Security in 2001 and as Director of National Intelligence in 2005. He was appointed to the Iraq Study Group in 2006, but resigned upon his nomination as Secretary of Defense. Gates recently wrote a summary of his vision for DoD in Foreign Affairs

Gates has written three books: Iran: Time For A New Approach (with Zbigniew Brzezinski and Suzanne Maloney), From the Shadows: The Ultimate Insider's Story of Five Presidents and How They Won the Cold War ,and Understanding the New US Defense Policy Through the Speeches of Robert M. Gates

Timothy Geithner (Treasury)

     

As president of the Federal Reserve Bank of New York, Geithner has been in the eye of the recent financial storm, but who is he? To be fair, Federal Reserve bankers usually keep a low public profile, so Geithener's relative anonymity isn't surprising. Washington and Wall Street insiders seem to think he is an excellent choice, which doesn't exactly fill me with confidence. On the other hand, it's hard to imagine anyone being confirmed that couldn't pass muster with those groups.

On the plus side, Geithner is said to be extremely intelligent, which can't hurt in the effort to correct the mess he's inheriting. He is also said to be very internationally-minded, and to view income-inequality as a serious problem -- two significant breaks from the current administration. Geithner was Undersecretary of the Treasury for Foreign Affairs under Secretaries Robert Rubin and Lawrence Summers -- two "moderate" Clinton appointees that aren't exactly blameless in the current SNAFU. Geithner is also a member of the Group of 30.

Geithner has been enthusiastically endorsed by a couple of economists who do have significant public profiles: Former Secretary of Labor Robert Reich and recent Nobel Laureate Paul Krugman, so I guess we'll all have to give him the benefit of the doubt for now.

 

Eric Holder (Justice)

     

Despite Holder's extensive resumé, the press has generally focussed on two things: If confirmed, he would be the first African-American Attorney General (actually he has already been acting Attorney General pending Ashcroft's confirmation), and he has publicly acknowledged that he gave former president Bill Clinton questionable advice concerning the Marc Rich pardon.

I think the public should know more than that. Holder will be succeeding, in my opinion, the three worst Attorneys General in American history, and his task will be nothing less than to restore respect for the rule of law in America. He is said to be extraordinarily even-handed both as a prosecutor and as a jurist. If that means he will apply the law without prejudice to the rich and powerful as well as to the disenfranchised, great! If it means he will do the politically expedient thing to avoid rocking the boat, I fear for the Republic. Congress has already chosen that path. There is no doubt that any number of high-profile public crimes have been perpetrated on George W. Bush's watch. The question is: will the lesson be "no one is above the law", or "you can't fight city hall?"

 

Ray LaHood (Transportation)

     

Bipartisanship was a theme of the Obama campaign, but many were suprised by his nomination of outgoing Republican Congressman Ray LaHood for Secretary of Transportation, not so much because of his party affiliation as because of this relative lack of transportation credentials. LaHood is one of those populist Midwestern Republicans, said to be a decent man and a good manager. He has voted with the Democrats on a number of transportation-related issues.

One clue is that in Washington-speak "transportation" boils down to the ongoing feud between roads and rail. (Can't we have both?) In that regard, LaHood and his associations in the House of Representatives might be helpful in implementing a long-overdue overhaul of the nation's rail system. Beyond that, this one's a puzzle to me.

 

Janet Napolitano (Homeland Security)

     Janet Napolitano received her Juris Doctor degree from the University of Virginia Law School, which certainly signals a new direction for the heretofore mostly useless Department of Homeland Security. She has been an outstanding two-term Governnor of Arizona and a rising star in the Democratic party. Since her appointment will cede the Arizona governor's mansion to Republican Secretary of State Jan Brewer, one can only assume tha Obama intends to make Homeland Security a real department.
 

Bill Richardson (Commerce)

     

Democratic presidential contender and Governor of New Mexico Bill Richardson is no lightweight, and many considered him a more logical choice for Secretary of State than Hillary Clinton. Speculation is rampant that his selection for the Secretary of Commerce spot signals an increased role for Commerce in the coming administration.

Commerce touches upon several key areas of the Obama agenda, including foreign trade, technology, and environment. Richardson's skill as a negotiator will certainly be useful in reshaping the American landscape as we move away from an oil economy toward something new and more sustainable.

Richardson is the author of two books: Between Worlds: The Making of an American Life, and Leading by Example: How We Can Inspire an Energy and Security Revolution

Ken Salazar (Interior)

     

Environmentalists are less than pleased with the appointment of Ken Salazar, whose record on green issues is described as "mixed." The mainstream position on environmental issues as regards the Department of the Interior has long been that we should have a "balanced" approach combining environmental protections with "constructive" use of public lands.

While this sounds reasonable, this approach has led us to the brink of gloabl catastrophe, with the best available science indicating that if we could magically reduce our carbon emissions to zero today considerable damage would already have been done which would play out over the next several decades. Salazar will not be operating in a vacuum, though, and depending upon the policies he is asked to implement, he could be a tolerable choice.

At least there is no indication a Salazar Department of Interior would exist solely to trade cocaine and hookers with representatives of the most egregious despoilers of the land.

Read more about Ken Salazar 

Eric Shinseki (Veterans Affairs)

     Former Army Chief of Staff General Shinseki is the first of many high-ranking officers demonized for telling the Bush administration the truth -- in this case that it would take hundreds of thousands of troops to stabilize post-war Iraq. He is a capable and dedicated officer who will doubtless do what he can with the antiquated mess that is the current Veteran's Administration.

I'd like to see the VA buy up the Afghani opium harvest, but that would upset the pharmaceutical companies, wouldn't it? Whatever else happens, look for Shinseki to develop innovative approaches to old problems and to rock the boat if necessary to get the job done.

Read more about Eric Shinseki 

Hilda Solis (Labor)

     

Hilda Solis is arguably the only genuine liberal in a cabinet notable for its centrist politics. As a representative for the 31st and 32nd California Congressional districts from 2000 to the present, she has had an excellent record on labor and civil rights issues. After decades of vigorous Republican Union-busting and luke-warm Democratic support, Solis just may be what the Democrats (and the country) need right now.

Read more about Hilda Solis 

Tom Vilsack (Agriculture)

     Tom Vilsack is the first Democratic Governor elected in Iowa for 30 years. He is another centrist, pick and some would say on matters of Agriculture leaning to the right. In the past he has come down on the side of large corporate farming operations on a number of issues. Note that the "free-market" zealots are strangely silent on the huge farm-subsidy budget, which although touted as friendly to the family farm actually favors agri-business. There doesn't seem to be much change in the offing here.

Clean Your Fuel Tank!

I recently had the dubious pleasure of replacing the fuel tank selector valve on my 1989 Ford F-150. It's a kind of Rube Goldberg contraption that uses pressure from a low-pressure pump located in the fuel tank to operate valves that direct gas to the high pressure pump, filter, fuel injector rail and back to the tank. I really don't expect parts containing rubber diaphragms to last much more than 20 years, so I wasn't that perturbed, although the availability of this Ford-only part left much to be desired. Compared to the caucus race of locating the part (for "only" $80) installation was uneventful.

Unfortunately, the substitution didn't fix my problem. To my surprise, the valve was actually good except for being stuck in one position by the accumulation of gunk from the gas tank. (I should have checked!) In this day of skyrocketing gasoline prices, you might well want to check your tank(s), because a car will still run with a disturbing accumulation of sludge in the tank, but it will perform a lot better with a good supply of clean gas!

Siphon a little gas from your tank into a mason jar and compare its color to some clean gas from an approved container. Is it nice and light, almost clear -- or is your gas an amber yellow tending toward brown? If so, you probably have an alarming accretion of tarry goo in your tank. Gasoline, kerosene, and Diesel fuel are all petroleum distillates -- refineries simply isolate a particular class of hydrocarbons from crude oil using an elaborate "still" called a fractionating tower. They also alter their product mix by "cracking" and polymerizing, but we won't go into that -- it's enough to know that the long-chain hydrocarbons (like gear oil) are dark and viscous, while short-chain fuels are light and fluid. Gas is really just very thin oil.

Of course everybody knows you can't make 200-proof moonshine without distilling your mash more than once, and your fuel isn't all one type of hydrocarbon molecule, either -- there are lighter and heavier molecules mixed in with those with average-length chains. Over time, the shorter-chain molecules are burned or evaporate, and the longer-chain ones accumulate as a tarry sludge in the bottom of your tank. As you add gas some of this residue dissolves, adulterating your fuel -- eventually to the point where your electronic fuel injection can no longer cope with the garbage you're feeding it.

Removing your fuel tank is relatively straightforward. Generally speaking you will find a fill tube, fuel delivery and return lines, an electrical connector and a vent line to be detatched. You then only need to empty the tank and remove the bolts that secure it to the frame. If you don't already have one, a shop manual for your particular vehicle is recommended for more detailed instructions. A floor jack is helpful in this procedure, but not absolutely required.

The traditional method of cleaning a fuel tank is steam cleaning, but I was unable to find anyone who still offers this service locally. I have no idea what automotive repair shop hours are going for these days since they priced me out of the market years ago, but I suspect that if you do find someone to clean your tank, they will charge you nearly the cost of a new tank. That would account for the disappearance of the service. The prospect of taking a perfectly good tank to the landfill didn't appeal to me, so I devised the following cleaning procedures:

If the design of your tank is such that you can get your hand inside it, begin by scraping as much goo and rust from the inner surfaces as you can. This is a thankless task, but its fast and productive, so keep at it using whatever paint scrapers, putty knives, pry bars, and wire brushes you have on hand. After removing all the debris you can reach, the following procedures will be much more effective on the relatively small amounts of contaminants that remain.

Old-fashioned soap-making involved mixing grease (usually lard) with caustic soda or lye (NaOH). You can remove the oily residues from your tank with crystal drain cleaner. I used Crystal Drano, but any brand should be fine. You might also use any suitable oven cleaner. These products are hard on skin and eyes, so the use of rubber gloves and safety goggles are recommended, if not expected. You don't have to saponify all the tar in your tank, but just enough to dislodge it from the metal surfaces, so go easy on the lye and add more as required. Be sure that all the surfaces of the tank get a good soaking.

Once the tar is removed, you're likely to find hydrolyzed aluminum silicates in the tank -- better known as dirt. You can remove this by sloshing around a strong solution of laundry detergent or trisodium phosphate. Lather, rinse, repeat. When the soapy water comes out clean, you've done the best you can.

If your tank is polypropylene, count yourself lucky. If it's steel, you're going to want to do something about rust. Due to the nature of metallic bonding and the accumulation of electrical charges, "rust never sleeps," but you can slow it down a little. The "right" way to do this is by lightly sand-blasting or bead-blasting the interior of the tank. You could do the same thing with sandpaper if you could reach all the surfaces. Of course, the paper is just a convenience -- the essential abrasive is sand.

Sponge out the inside of your tank and let it dry thoroughly. Wet sand will clump together and won't expose as many jagged little surfaces as dry sand. Put a generous amount in the tank and tilt it back and forth. If you were using sandpaper, you know that the harder you pushed down the faster this would go. Unfortunately, you can't exert much pressure here, so just be patient and think of what a great work-out you're getting. Peek into the tank with a flashlight to see how you're doing. It is not necessary to sand the tank down to bright metal, you just need to remove the loose rust scale. If you like, you can use phosphoric acid (better known as naval jelly) at this point.

Don't try to remove all the rust. Your tank started out as galvinized steel, but now that the zinc coating has eroded away, the phosphoric acid can convert the thin coating of rust that remains to metalophosphate, providing at least some corrosion resistance through passivation. You can ensure that all the acid is neutralized by treating the tank with baking soda. Be sure to rinse and dry the tank thoroughly, and you're done!

If you tend to be a picky, don't let the perfect become the enemy of the good. Your tank will probably never pass a white glove test, but think of the pounds of gunk you've removed rather than the ounces or grams that remain. On the other hand, if you're a lick and a promise sort, perservere. A little elbow grease now will save you a lot of grief down the road.

If all this seems like a lot of trouble to go through, it is. I'm sure many more people will simply replace their tanks than will follow this procedure. Hopefully, a few will buy their new tanks here. On the other hand, there are some who are as stubborn as I am, and quite a few who are offended by the cultural notion that everything is disposable. If you do rehabilitate your tank, at some point it will occur to you what a poor choice petroleum fuels are. You might even wonder why gasoline is the "mainstream" choice, and gaseous fuels like methane are termed "alternative" fuels.

Consider the fact that many fleet operators converted to compressed natural gas (CNG) decades ago, because it was more cost-effective, yet there is only one production CNG car on the market today, and practically no CNG filling stations, despite the fact that anybody with natural gas and electicity can "Phill" up at home. Consider that GM built and leased an electric car, the EV1 (to comply with California's stringent emissions requirements) that everybody seemed to love, but killed it because it didn't break down and contribute to the lucrative repair side of their business.

That goo isn't just in your tank. It's in your fuel lines, fuel gauge sender, injectors, valves, cylinders -- throughout your engine really. All completely unnecessary, but very lucrative for the special interests that continue to maintain that alternative energy technologies of twenty years ago "will take decades to develop." Don't let the fact that T. Boone Pickens' plan is to make a pile of money for T. Boone Pickens distract you from the fact that cost-effective alternative energy is available now.

New aStore: Popular Non-Fiction - Categories @ Amazon.com

What do we mean by "Popular Non-Fiction?" It 's probably easier to describe what we don't mean: Amazon.com has a book category "Professional & Technical" which covers a number of fields in science, law, medicine, business and engineeering. This "Popular Non-Fiction" aStore is meant to cover everything else.

As is common with Amazon's categories, there is some significant overlap here: Theoretically, the Mind & Body Health section here should include books intended for a general audience, while medical & nursing books should be in our Technical Bookmania store. In fact you will find a lot of books listed in both places that don't conform to this convention. This is should be only a minor irritation, since those books are usually listed in both places, but it's a good idea to check both.

Below you will find our current category listings for this new store. In the near future (after the search engines begin to find some of these pages) we'll be expanding it to include the relevant subcategories.
