If you sync the mirror on a RAID-1 and take one mirror out, then you no longer have RAID. Moreover, if you pop in another disk and wait for it to sync you will overload the system.
Might as well use external disks attached via USB2 and copy what you want to them.
EMC has a feature called Business Continuance Volumes (BCV) whereby you have something like Logical Volume Manager (LVM) and snapshots, but with multiple RAID-1 mirrors, AND the mirror can be remote on another EMC box.
Still limited by how fat the pipe is, and not affordable for home use!
Those who have EMCs use robotic tape libraries, and pop out the tapes for offsite storage.
First it was Roland Piquepaille pushing articles to his primidi site, then it was Carl Bialik from the WSJ pushing articles from the WSJ, and now it is ** Beatles Beatles linking to his George Harrison site.
I am bothered by Slashdot favoritism as well, but more so by the lack of any mechanism of feedback and the deaf ears it falls on. Any site would have a forum/topic for comments from users.
When I commented on this last October, I lost mod privileges, which used to be every few weeks for the last few years.
Today, CmdrTaco posted something on the topic, which I have yet to read. Not expecting any break throughs though.
This site is about a) the vast readership, b) the superior threading/threshold and c) the comments.
Instead of developing stuff for the desktop, where you have to chose if it runs on Windows, Mac OS/X or Linux, why not tinker with something web based?
Start with LAMP (Linux Apache MySQL PHP) because it is available everywhere on virtually all hosts, or go a little bit further with a framework such as Drupal.
If you are a bit more adventurous and do not care about hosting availability, consider Ruby on Rails.
The reason is, it is not ethics that is driving all this, but rather it is fear. Fear of the law, fear of "ethics committees" in the field of practice, fear of negative publicity, fear of funding vanishing,...etc
This is what Drummond and Gefen think is the reason.
Ms. Drummond and Mr. Gefen believe that the company bases the decision on a customer's creditworthiness. "If you have the financial history, they let the meter run," Ms. Drummond said.
One more unsubstantiated claim in this article.
(Not that I am defending Rogers or big corporations, but this whole thing smells of sensationalism. All the juicy attention grabbing keywords, Hezbollah, Terror groups, cloning of exec phones, conspiracy of silence,...etc.)
This is an excellent analysis piece. Well thought out and well written. It is the kind of thinking ahead of the curve that few people do. Thanks.
One good test for whether that newspaper you gave as an example will see the light is whether they:
a. Experience the Slashdot effect. b. Wonder what is going on. c. Check their web site's log. d. Read your article. e. Give to the higher up in the hierarchy. f. ??? g. Profit
If these people can save their business, f. would be that they may take you up on your offer on the computer column you mentioned.

Most Arab countries filter the internet behind proxy servers and cisco firewalls.
The only two Arab countries that I know that filter the internet at a national level are Saudi Arabia, and the United Arab Emirates.
The other 20 countries do not filter it. This even created a market for some ISPs who sell their service as safe for families and children, e.g. PureNet in Egypt, the most populous Arab country (ca. 70 million). This is very similar to the Christian ISP by the same name in the USA.
You realize that non-Arab countries do filter on a national level, the most well known example being China, and (IIRC) Singapore.
Now, all governments, the USA included, passively listen and observe traffic on the net for various intelligence, military and political reasons.
I have seen a large number of "Carl Bialik from the WSJ" articles recently.
This time, two articles from the WSJ are included.
He does not even use the term slashdotted correctly in his submission, thinking it means "discussed on Slashdot", rather than the right meaning.
This is just like the Roland Piquepaille case. When will the Slashdot editors confront the accusations, and lay the matter to rest: either they fess up and disclose that there is a deal, or come out and say that there is isn't one.
The editors are becoming less and less responsive to their audience as time passes.
The only time in recent memory was Scuttlemonkey responding with non-convincing answers on editorializing, defending not changing the slanted wording of a sumbitter. This is not good.
The scammers have been showing a lot of creativity lately.
I get the classic ones (African dictator/official dies and widow/son wants his money transferred for a hefty share). But I also get ones that have a Christian theme], others with an Islamic tone [baheyeldin.com], and yet another with an Arab tone featuring none other than Yasser Arafat, with links to news articles from ABC News, just after he died.
These guys could use their imagination writing fiction or something. If they had better English that is...
If I were to have my way, DST should be in winter not summer, so when I am going home, the sun is still up, and it is not dark.
Failing that, let us unify time across the whole world. UTC would be the time everywhere, anywhere, any time of the year. It would be hard when setting up appointments and such, but we are in a mess anyway.
I have to use a tool like Time And Date to know what time it is in a city I am calling.
As someone living in Ontario, this is yet another fine mess we got ourselves in, in the name of trade and economy.
As others have pointed out, we do trade with China and Europe and they are not on the same zone we are in.
As much as I despise those scammers, I have to admit that they are creative in a weird source of way.

Slashdot Mirror
It is amazing that such a man gets quoted by Dick Cheney on a Christmas greeting card that says:
...
"And if a sparrow cannot fall to the ground without His notice, is it probable that an empire can rise without His aid?"
Talk about out of context
SWSoft are the makers of Virtuozzo a commercial product that allows hosting companies to offer Virtual Private Servers.
A rival technology is Xen from Cambridge University, which is free.
Technologies development for large systems eventually find their way to the home user in one form or the other.
...etc.
Logical Volume Managers started on big iron, now it is available for the home user on Linux. The same goes for tapes,
So, eventually, the BCV stuff with a remote solution may find its way to the home.
That is why I brought EMC into the discussion...
I did not mean incremental point in time.
What I meant is a full copy of the main disk (or selected directories) that can be taken offsite.
Mirror copy in the same machine is useless if the power supply toasts the disks, or lightning strike.
Mirror copy on a separate disk is a lot better, but still does not protect one from a hurricane or house fire.
If this is not a tape, then at least a USB2 hard disk that is stored somewhere else (e.g. at a friends house).
What?
If you sync the mirror on a RAID-1 and take one mirror out, then you no longer have RAID. Moreover, if you pop in another disk and wait for it to sync you will overload the system.

I have written two articles on this:
- Tapes are still the most efficient and cost effective form of backup.
- How to backup a Linux home network.
Granted, disk capacity is growing faster than tape capacity can keep up, but RAID cannot be an offsite bacup solution.
Perhaps two disks in a USB portable housing is a better solution. One on site and off site, rotated weekly.

I have been a long timer too (1999 I think).

I understand that mail order in the USA is not taxed, unless the purchaser is from the same state that the mail order house is in.
So far, ecommerce had the same rule (or similar).
If this gets implemented, then will it apply to mail order as well, or will it be for ecommerce only?
What about if an American buys from a Canadian business via the internet? Will the Canadian business be required to collect US state taxes too?

So, it is not really ethics per se
This is what Drummond and Gefen think is the reason.

First, she said her phone was "stolen", then she said Ted Rogers' phone was "cloned" by a group.
...
...
...
Also, she was on a trip to "Israel", and the "group" has "links to" Hezbollah.
Then the article says that Rogers Co. knew that Ted's phone was cloned
That alleged group is not named, nor what the "links" are.
Makes for a great headline though: "How a terror group cloned Ted Rogers' cellphone"
She is not a high ranking exec, just an academic, so why did the pattern of her calls not trigger a service stoppage for her?
Her husband is a "technology journalist", and this is published in Globe Technology
I am not sure if the article got mangled in editing or it was incoherent to start with. The BS meter reading just shot up
Just to put some context, this is a reference to the September that never ended.

One good test for whether that newspaper you gave as an example will see the light is whether they:
a. Experience the Slashdot effect.
b. Wonder what is going on.
c. Check their web site's log.
d. Read your article.
e. Give to the higher up in the hierarchy.
f. ???
g. Profit
If these people can save their business, f. would be that they may take you up on your offer on the computer column you mentioned.
Write us back when/if they get in touch with you
Anyone remember them?
This seems like RealNames, all over again.
Here are examples from two web sites (those with a share of less than 1% are omitted, unknowns are crawlers).
The first is mainly a techie site. Audience are tech savvy.The other is for non-techies.See the difference in MS IE vs. FireFox share? It is about 3X as much
Your assumption compares a a 9 to 5 job 5 days a week (intern) with a part time/spare time, do it at your own pace, project kind of assignment.
How are you going to backup that monster?
You said you do not need data redundancy, since backup is nearly impossible, how are you going to survive a disk crash (they *will* crash!)

The author is Bosnian, which means he is European.
The name is used elsewhere of course in Muslim countries. It comes from the Arabic root 3-R-F which mean "to know", "knowledge",

Hey man.
Thanks for a very sane post.
Unlike those who claim that MySQL does not have tablespaces.
I agree with you that triggers and stored procedure are often more trouble than what they are worth, and better in the middle tier.
Views however, are a nice feature to have.
With 5.0 coming soon, it will have all these bells and whistles for those who need them.
What worries me is that new acquisition of InnoBase by Oracle a few days ago. I wrote about that here.
