^ Um...actually the data chunks and parity info are distributed among all the drives in a RAID-5  array by the controller. There isn't a unique "parity drive" per se AFAIK.  :)

Strictly speaking, you don't mean the Internet, you mean the web. The Internet started in the early 70s, and FidoNet was -- what, 1985?

Actually, I did mean the Internet in that I was referring to Fido's behavior as a 'network of networks' communicating under a commonly shared protocol; as opposed to 'the web', which I always took (perhaps erroneously) to refer to the global collection of linked hypertext documents accessible via the Internet.  :)

But some of my definitions date to 'way back when' so they could well be obsolete by current standards.  ;D

(And you're correct.  Most people will have no idea what we're talking about. But that's good in a way. Because that meant they missed out on all the aggravation (even if they also missed out on all the "fun") of running a Fidonet node. Onward! :Thmbsup: )

Weirdest thing about RAID-1. When it breaks, it sometimes takes out both drives.
Shit happens :) - drives from the same batch can die shortly within eachother (especially if you have very disk-intensive rebuilds... mirroring isn't too bad, raid-5 is BAD). And then there's stuff like power surges etc. So yeah, stuff dies.


It wouldn't have been so disturbing if it were just the drives that failed. They're mechanical devices so you have to expect that. "Omnes vulnerat, ultima necat," as those old sundials used to say.

But it wasn't the drives that caused the problem. In both cases it was a controller issue (one HP and one IBM branded) using drives originally installed by the manufacturer. Since these are big league server manufacturers, I'm confident they did the necessary mix & match games to minimize the chance of getting two "bad batch" drives on the same machine.

In both instances the controllers unexpectedly started writing total garbage to both drives thereby rendering them useless. In the case of the IBM card, a firmware update corrected the "engineering issue." With HP, a replacement was necessary because there was a "marginal hardware condition" on the card.

Having it happen two different times on servers from two different manufacturers is a little too much bad luck AFAIC.  ;D

If you want speed, get an SSD. If you want redundancy, do regular backup.
...and possibly couple it with RAID Mirroring. That does add real redundancy and isn't (just) for downtime reduction :)

True.  :)

Unless you have a controller issue which screws up both drives. :o

Weirdest thing about RAID-1. When it breaks, it sometimes takes out both drives.

I had this happen to clients twice in my career. So it can't be that rare an occurrence in the field. Which is why I'll only use RAID-1 for mirroring the OS drive thereby reducing it to a 'downtime reduction only' function.

Because I can always reinstall a disk image or (if it comes down to brass tacks) do a scratch reload of the OS (*choke*) without losing anything critical belonging to the client.

---

Never tried RAID with SSD. (Not being wealthy has its downsides. ;D) Is anybody doing that? And if so, does it adversely affect the life of the SSD drives? Mirroring probably wouldn't. But RAID-5 should since there's so much extra R/W activity generated by all the striping plus parity info being written to the drives. (Note: Save a dinky 1 meg file to a server with RAID-5 and watch das blinkin' lights come alive with motion and color. Freekin' dance of fireflies is what it is! Save anything to a RAID-5 array and it goes nuts "gettin' busy.") That can't be good for an SSD drive over the long term.

Anybody know anything about this?  :huh:

Good lord! There are so many...

JavelinPlus - radically powerful financial modeling software frequently mistaken for a spreadsheet. I used this extensively when it first came out back when I was in corporate financial planning. I have yet to see anything that comes close to it in terms of design or functional elegance.

From Wikipedia:

Javelin encourages viewing data and algorithms in various self-documenting ways, including simultaneous multiple synchronized views. For example, users can move through the connections between variables on a diagram while seeing the logical roots and branches of each variable. This is an example of what is perhaps its primary contribution—the concept of traceability of a user's logic or model structure through its twelve views. Among its dynamically linked views were: diagram, formulas, table, chart, QuickGraph, worksheet, notes, errors, macro, graph. A complex model can be dissected and understood by others who had no role in its creation, and this remains unique even today. Javelin was used primarily for financial modeling, but was also used to build instructional models in college chemistry courses, to model the world's economies, and by the military in the early Star Wars project. It is still in use by institutions for which model integrity is mission critical.

Javelin received multiple awards, including: "Best of 1985" for technical excellence from PC Magazine[1]; "Most Significant Product" from PC Week; and "Software Product of the Year".[2] 'The Infoworld award apparently created some consternation in the top ranks of number two Microsoft:'

    "Then there was the year Microsoft's new Windows spreadsheet, Excel, was up against start-up Javelin Software's Javelin spreadsheet for InfoWorld Product of the Year. Although Excel was a beautiful extension of the existing spreadsheet concept, Javelin had imaginative features, says Michael McCarthy, InfoWorld reviews editor from 1984 to 1990 and current publisher of IDG's San Francisco-based Web Publishing Inc., producers of JavaWorld and SunWorld. "I persuaded InfoWorld to give Javelin Product of the Year," McCarthy says. "At the InfoWorld dinner at Comdex, when they gave out the award for Product of the Year and Excel came in second, Bill Gates got up and stomped out of the room in front of everybody in a spectacularly rude manner."

tpasbox.gif  TurboPascal - time was, if you wanted to write your own "real" programs, "TP three-oh-two" was what you used. (Still available for free download courtesy of Borland!)

Business programs benefited from the BCD edition (originally extra $$$, later incorporated into a single release) which avoided floating point arithmetic hassles by providing binary coded decimal real number math capabilities.

From the README.TXT file:


WELCOME TO TURBO PASCAL 3.0
                     ---------------------------

This file contains important information not found in the Reference
Manual.  Included is information on how to get technical help, a

corrections to the Reference Manual, and a complete list of files on
the distribution disk.  Since this file contains information important
to you, please read it in its entirety; hopefully it will answer any
questions you may have.

Special Note:  Turbo Pascal now comes complete with three versions of
the compiler.  The standard compiler: TURBO.COM, the compiler with
support for the optional 8087 math coprocessor: TURBO-87.COM, and the
compiler with BCD (Binary Coded Decimal) real number support for precise,
business oriented computations: TURBOBCD.COM.  Simply recompile your
source code with one of the compilers to take advantage of the optional
real number support.  Please note that to use TURBO-87.COM you must
have an 8087 coprocessor chip installed in your computer.  Most
computers do not come with the 8087 chip installed.

General Software Discussion / Re: How necessary is the UAC in Windows 7?
« Last post by 40hz on August 04, 2011, 01:13 PM »
But I find myself worrying about the popularity of these programs, especially MSE.  If the overwhelming majority of people use the same anti-virus program, be it MSE or any other, doesn't that make it easier for the bad guys to develop malware specifically designed with that particular AV program in mind?  (Hmmm...perhaps I should change my username from cyberdiva to worrywort  :(  )

It's a legitimate concern. However, it's relatively moot since, in practice, it's far easier and more productive to try to discover and exploit an unknown vulnerability in the underlying OS than it is to try to fox or disable an AV utility. And the malware writers know that.

Today, most systems are fairly secure by default. And with the addition of any decent AV package they're remarkably secure. Add in some common sense - plus a smart user - and they're virtually impregnable.

The weakest ink in the lineup is the user. That's why so many documented "successful exploits" rely so heavily on "social engineering" - which is a fancy way of saying "tricking the user into doing something dumb."

Day Zero exploits are a whole 'nother issue. Fortunately, most of the really dangerous ones are spotted and dealt with long before they fully activate.

Keeping your system fully updated will protect you from "zero" exploits most times unless you're one of the unlucky early victims that sounded the warning cry to the rest of the pack. (Let's face it: we all knew that, sooner or later, the snakes were gonna get lucky and take out at least one meerkat - even if we didn't think it would end up being Flower.) Not much you can do about that except restore from backups if it happens to you. But again, it's a long shot you'll ever end up being in that category if you're doing everything else right security-wise.

Stuff happens. Best just do what you can do to avoid problems. After that, try not to worry about it too much. Sharing a glass of fine Merlot (or a microbrew) with friends who aren't always talking about computers helps too. Highly recommended, :)

sticky-note-backup1.gif


As Stoic noted, with the size of today's hard drives, the big problem with "overnight backups" is we're now running out of "night." ;D

The most important thing to protect is your files. Everything else can be reinstalled from DVD media or download if you have to. So put your primary emphasis on data first.

For user files your best bet would be to use a file synchronization utility that has a "synchronize on shutdown" option.

There's dozens of paid and free apps to choose from. Do a Google or visit a reputable software aggregation site like FileHippo, Snapfiles or Tucows and nose around. (Tip: Also make it a point to read the user reviews. Not all utilities are created equal.  :mrgreen:)

Configure your sync utility for which directories you want to 'backup' and point it to the external drive. Then tell it to sync whenever you shut down.

Now, every time you issue a shutdown command, you can walk away, empty coffee cup in hand, fairly secure in the knowledge that the most recent versions of your files will be copied over to your external drive.

Note: first time you do this will take some time since all the files will need to be put on the external drive and have a sync database created for them. But after that it should go pretty quickly unless you've added and/or updated thousands of files between your last synchronization. Then it might take something like 15-20 minutes.

I'm a big fan of synchronization. Most of my daily "backing up" gets done that way.

Note: there's also free and inexpensive remote online "backup" services (like SpiderOak, iDrive, etc) that will basically do the same thing. All such services have provisions for automatic (i.e. scheduled) as well as ad hoc backups. This wouldn't be workable for massive collections of...uh... 'archived' movies or...um... porn photo galleries. But it might be a very good place to store that computer code or draft of the report your boss is waiting for. It's also good for any other collection of files you'd hate to loose if your house or office burned down. :tellme:

For bigger or periodic or 'versioned' backups I'll either use Microsoft's included backup utility (if I'm in Windows7) - or a copy of Cobain Backup.

System images and restoration snapshots can be handled by Microsoft's backup in Windows7 - or using a copy of Macrium Reflect or Clonezilla (if you're feeling adventurous!).

Note: I never use an "automatic" or "scheduled" feature to create disk or partition images. For some odd reason, they've always been unreliable for me. If I need to create one, I do it explicitly. Don't know what to suggest to you if you're forgetful about things like that. Maybe a calendar/reminder might help?

Fortunately, you don't really need to image drives all that often if your data is already backed up. I'll usually create an image immediately after I've setup and tricked out a new machine. But after that I'll only reimage following major software updates (like Windows or MS Office service packs) or after an important new software installation.

Hope this was helpful! :Thmbsup:

For the non-tech users, I see more problems caused by security suites than I do by malware.

As Carol recommends, just install Microsoft Security Essentials, use Windows' built-in firewall, stay caught up with your system updates - and be done with it. That and a little common sense about what attachments you open and what software you install will more than suffice for 99.9% of all users. And it will do so without the headaches 3rd-party security suites can cause.

Time to stop the insanity.  

Take the money you save by not purchasing Norton or McAfee and buy yourself a nice little USB hard drive so you can finally start doing those backups you keep putting off.  8)

Microsoft has a good introductory article that gives you what options are available for various levels of "collaborative" use of an Excel workbook. Link here. This is where I point my clients initially when the question comes up. Most are interested in the section that's headed: Allowing multiple users to edit a workbook simultaneously. Scroll down about midway to find it.

Cool ... Just sent that link to a client, Thanks!

@imtrobin - take a look at Alfresco for a Sharepoint alternative you can host yourself.

I don't know how well it may meet your specific needs. And I don't have much experience with Alfresco beyond setting up a small test environment and playing with it for a few weeks a while ago. But I do recall being very impressed with how well it stacked up against Sharepoint in a feature by feature comparison. It's pretty much the acknowledged "worthy competitor" to Microsoft's collaboration offerings.

Alfresco is a FOSS product so there's a free unsupported community edition you can download if you want to give it a try. Just commandeer a spare PC, or set up a virtual machine, load up your software and have at it. Only some hands-on experience will allow you to accurately determine if Alfresco might work for you.

Fortunately, it will only cost you your time to check it out.  8)

A government's primary function is to provide necessary services it doesn't make economic sense (as in 'not profitable') for a business to provide. These services include things such as public safety, assistance to the needy and aged, and public education.

This is one of the reasons the endless mantra about "privatization" is so misguided. As is the argument that government should be run "just like a business." Because there are many necessary things that need to be done, or made available, if you want to live in a largely benevolent and just society. The only problem is, there's no money to be made providing them.

That's where government comes in. It's our publicly supported "loss leader." And hardly anybody who thinks responsibly would want it any other way.

Otherwise you run into such perversions as cable companies and telcos bringing municipalities to court for providing broadband and wireless services that these very same companies (most of which were granted effective monopolies and are receiving ongoing favorable tax treatments) are simply unwilling to provide to their markets. And this despite all the promises made by the industry in exchange for being allowed to do it "their way" with minimal governmental regulation and oversight.

And guess what? It doesn't work! It's a FAIL.

Just finished rereading Zen Flesh, Zen Bones: A Collection of Zen and Pre-Zen Writings by Paul Reps and Nyogen Senzaki. I try to reread it at least once every few years, both for pleasure and for the new insights it provides.

long.png

Amazon has a pretty good description of what it's about:

With over one million copies sold fifty years after its first printing, Zen Flesh, Zen Bones has inspired countless lives. Hailed as the most profound religious philosophy ever, this far reaching system of aesthetics truly tackles the question: What is Zen?

Zen Flesh, Zen Bones has been sharing wisdom and enlightenment with readers since 1957. An inspirational four-books-in-one volume at your fingertips, this collection of Zen and pre-Zen writings includes: 101 Zen Stories, a collection of tales that recount actual experiences of Chinese and Japanese Zen teachers over a period of more than five centuries; The Gateless Gate, the famous thirteenth century collection of Zen koans; Ten Bulls, a twelfth century commentary on the stages of awareness leading to enlightenment; and Centering, a 4,000 year-old teaching from India that some consider to be the roots of Zen. ..

About the Author

Paul Reps was the author of several books of poems and prose inspired by Zen, including Zen Telegrams.

Nyogen Senzaki, an internationally renowned Buddhist scholar, was a homeless monk studying and wandering the land from monastery to monastery. His wandering eventually brought him to the United States, where he lived for over 50 years.

I first read this book the summer before the start of my freshman year in high school.

My grandmother had a house on Cape Cod that she occasionally rented out during the summer to friends and people with 'good references.'  

In keeping with one of the many traditions of Cape Cod "summer house" residence, her guests often left behind whatever books they read while on vacation. Over the years, my grandmother's house (by the beach rather than "over the meadow and through the woods") acquired a fairly large library of abandoned paperbacks and inexpensive hardcovers that spanned the gamut of reading interests.

Her living room had a wall of bookshelves on either side of a built-in fireplace. When she first bought the house, these shelves mostly held knick-knacks and her antique Sandwich Glass collection. As the years went by, the books gradually crowded out her collectibles, forcing her to finally move them to a locked (to keep out the books!) curio cabinet she bought specifically to house them.

Most of the books were the usual "summer fare" light espionage, murder mystery, 'bodice-ripper', horror, and (rarely) fantasy & sci-fi titles. But hidden within this collection of literary trash were a few dozen real gems such as The Hobbit and Frank L. Baum's complete collection of 14 illustrated Oz Books in hardcover.

One day, while rummaging, I found a slim little book wedged between and half hidden by a couple of large craft books. It was Zen Flesh Zen Bones. I started reading it, and got hooked before I got less than ten pages into it. And while it may sound trite, I can honestly say this little book changed the course of my entire life - and set me off on a spiritual adventure that's continued to this day.

Dynamite little book.

Read it! :Thmbsup:

-----------------------------------------------------------
Cautionary note: This book will change you.

The interesting thing about Zen, and it's way of looking at the world, is that it will change you. And it will do it without your doing anything other than becoming aware of what Zen teaches.

No need for rituals (although there are ritual practices if you want them) or complex rules of ethics (Zen is both ethical and moral - yet it paradoxically professes no creed or moral dogma).

Just read through this book and you'll find your perceptions and beliefs changing in many subtle ways - whether you agree or disagree with what you read. Not that there's anything to really disagree with since Zen doesn't espouse any specific beliefs or doctrines. It simply asks you to become consciously aware of what you think of as yourself and the world around you.

Then, once you've reached that level of awareness - look both inward and beyond. (Note: see the Ten Bulls for one roadmap of how to get there!)

What comes next will both amaze and delight you - even if you'll never be able to actually put into words what you've discovered.

So are the taxes of all the people, institutions, and other companies that stand to benefit from it.

That's the problem with arguments for protectionism in the name of the "greater good." Most times, they don't hold up. :)

Of course said businesses (who make a living off indexing what are public records) might consider reimbursing the government for the underlying "raw materials" (funded by taxes) they make their living from.
