No. But, the people that design and position the steering wheels, pedals, shifters, turn signals, gauges and door handles in such a way that *anyone* can go from one car to another without *any* difficulty or re-education might have some insight. Occasionally there are exceptions to this.
But, surely you have jumped into a friends car, a model that you have never before been in, in the dark and been able to drive it without *any* difficulty. Did you *ever* need to RTFM in order to drive a car, or worse yet, to get out of the car?
This is because most automakers have made intuitive design a science as well as an art form. This level of intuitiveness and uniformity is rare in software.
Now, try to prove your point by naming some post 1946 advances. Be sure that your choices are just as significant and far reaching as the pre 1946 ones that you have listed.
This isn't much of a firewall when there is no logging or alerting. With this approach you basically have a solid state packet filter and if that's what you want, a Linksys box would still be a better solution.
There are a lot of things that can be done but, one has to ask: Other than doing it for the sake of doing it, what's the point?
You certainly have quite a challenge here. Some of the newer LTO drives can, theoretically, achieve 55GB per hour transfer rates but, realistically you will get far less. Using an array of drives will allow you to increase this performance but definitely not as much as one would like to think. With a two drive array, most people expect to double their performance but, a 30% increase is likely as much as you will see. That said, it would require a 4 or 5 drive array in order to achieve the theoretical throughput that you desire. This all assumes that your server hardware and OS and backup software can in fact feed the array fast enough.
I'm afraid that your only realistic options are to either get a larger window, which is probably unlikely, or perform live backups and bear the performance degradation during that time. The only other alternative that I can think of would be to mirror your data to secondary disk based storage and then backup the secondary storage off line. Any which way, I'd be amazed if you got 100 Gig an hour.
This would make the cell phone networks VERY happy. Presently you have a cell phone with a 1000 minute plan. That's a lot of chitchat for the money and it may well last you all month. Now, with Intel's plan, you're laptop is connected to the cell network "always on", just like when you are making a call on your phone. Now, instead of the 1000 minutes lasting all month your laptop eats them up in two days. That means you have to buy more minutes from the cell networks. They win!! Big time!!!
I agree that it is possible to open a hard drive and put it back together and have it work. I too have done this several times. I have have several antique servers that were shut down for the first time in years and their drives froze. The bearings go out, the motor dies, what have you. I would give the spindle a litlle nudge to get it spinning again or replace the motor and boot the server right back up. But, I also regarded those drives as contaminated or failed and immediately mirrored the data to a new drive, discarding the old one.
Sure I might have been able to use those drives for years more but, I could have just as likely had a microscopic piece of dust hose a 30GB database two weeks later. Drives aren't so expensive that I would take that sort of risk.
First of all, this is definitely an opportunity to WASTE a good hard drive. But, beyond that, it is way too much effort for such a simple and stupid task.
The fact is that WD and others already make clear molded plastic covers for their drives. Sure you can't just go out and buy one but, surely you have seem display drives on countertops in your local computer store? You know the nice "dummy" drive with the clear plastic cover? If you are hell bent on seeing the inside of your drive, you simply need to scrounge up one of these display units, I have one on my desk, take the plastic cover and put it on your working drive. The contamination risk is only slightly less but, the work involved is far greater. 3 minutes with a screwdriver and your done.
All this assumes that you care to see your heads thrashing in the first place.
What do you mean you can't get it? You can get it (56bit) free, here. If you want 128bit it costs $2 a seat and if you want NAM, I think it costs $26 per seat. If you can't find a local reseller call Novell. It is available and, apparently, has been for more than a year.
It seems that everyone has become satisfied with ripping off M$ True Type fonts. That's why no one seems particularly interested in doing much work in this area. True Types are, arguably, the best looking today and there are thousands if not millions of them.
This is an excellent question. One that I have done a couple of AskSlashdots on in the past. I too encountered a similar situation where, I would like to use Linux but was not interested in yet another authentication mechanism. Nor was I slightly interested in managing, potentially, thousands of workstation user lists individually. I wanted a mechanism that was more reliable and functionally scalable than NIS and I wanted it to be usable by all systems. Basically I wanted a single directory for the entire enterprise.
I have done a lot of research on the subject and extensive testing. Naturally I would have preferred a free solution, which suggested that OpenLDAP would be the solution of choice. But there are numerous issues with OpenLDAP.
One big problem is that it does not scale well. Sure it can handle massive volumes of users but, redundancy and more importantly distribution or replication are not yet adequate for enterprise use. This is also compounded by the fact that I also had to tie in Windows 2000 systems and applications. While active directory claims to be LDAP compliant, it is broken from a standards perspective. This severely limits the use of Active Directory as the central directory, not to mention the fact that it requires add-on software from Microsoft in order to authenticate *nix systems against it. Furthermore, because of Microsoft's proprietary extensions it is not possible to use OpenLDAP as a replacement for Active Directory.
Thus far, the best that I have found is Novell's eDirectory. There is also a second Novell package that is required if you will also be integrating Windows 2000 and Active Directory, you cannot eliminate Active Directory. The second package is Novell Authentication Management (NAM). This allows eDirectory to manipulate and synchronize Active Directory to eDirectory pretty seamlessly.
eDirectory runs on almost any platform. It runs on Netware, Windows 2000, Solaris, AIX and most importantly Linux. It is super scalable and easily handles distribution and replication. It offers authenication management for just about any platform and it has reasonable support from various application developers.
If you use Windows 200 apps like Exchange 2000 you still *have* to run Active Directory as well as eDirectory but, with the NAM package there is no need to ever manage Active Directory. All of the management is done in eDirectory and anything that needs to go into Active Directory is automatically pushed there.
Novell also has a product which I have not yet tried. It is an XML based add-on to eDirectory. Basically it will handle synchronizing other various directories to eDirectory. For instance, if you run SAP or some such application that has it's own authenticatioin system, the XML product will perform two way synchronization between eDirectory and your applications native directory. This propogates any changes made in one directory to the other.
You can get a free copy of eDirectory for Linux here. (Registration required) It's not the free solution that I had hoped for but, it seems to be the best around and it isn't too expensive for enterprise level software.

Ooh Ahh. I'm not impressed.

It'll be tough, if not impossible, to use this on an airplane but, damn I like it.
I'mm still eagerly waiting for my mylar film LCD (ePaper), where I can roll up a 20"+ touch screen and put it in my briefcase or where ever.

True Type is from Apple. But, I was referring to the practice of copying the M$ True Type fonts from a Windows machine onto Linux boxes.
What is Coltan
Coltan killing elephants, gorillas and people
The Coltan Rush
Minerals Fueling War
Guns, money and cell phones
.
Does this technology use Coltan?
Frankly, after seeing what is going on in the Congo, I feel ashamed for even owning a cell phone.
