Been there, done that.
Automatic trade machines are common place. It may have caused the early 90s slump in the UK.
All the broking houses had them. So when a stock tripped everybody sold and the stock plummeted. Vicous circle. There's no upside because if a stock did well machines bought until the price went up.
I worked in the markets in London, I wrote some of the back office systems in the mid 80s to mid 90s. The market is as good or bad as Vegas or the horses. To think any different is to be blind to human nature. Think of it not as an investment but as a gamble.

I worked for a number of years developing case tools. I saw the tools used to great effect and also saw complete disasters caused by them. As long as you work within the confines of the tool everything will be quick and robust. Try and get clever and you might as well not use a case tool. The important word is TOOL not CASE.
say the task that fails is a editor, how does it restart? At the beginning, any input the user made until the task failed is lost. That is not HA.
MOSIX is HP, from what little I know it performs load balancing very well. It provides little or no HA features.
The failure rate is very dependent on the granularity of your system. If a block of work can be re-run then it provides no change. If a block of work cannot then it fails. 1 node failure can bring down a cluster.
No,
a beowulf will just allow you to disperese workload. Either at the process or at the thread with MOSIX.
In fact a HPC like MOSIX can result in reduced uptimes. If a machine has a 1% failure rate then what is the failure rate of 100 machines in parrallel?
The question all boils down to how granular your recovery process is. For a desktop you need very fine granularity and few current systems provide this. I think Tandem provides this by using special hardware and kernel patches for NT.
...but what about my desktop? I want to run my company on xterms connected to a large cluster. Problem, nobody has yet to provide High Availability for Linux or X. Not your heartbeat type stuff or MOSIX etc. But a cluster that I can hotswap entire machines and nobdoy loses uptime. Bits and pieces are there but not everything.
Yes I submistted an Ask/. but it's still waiting to be posted, only been there since Feb.
An object is neither good nor is it bad. The actions a person performs are neither good nor bad. A company is neither good nor bad. All are what they are.
The opinion a person holds of an object/action/company determines wether that object/action/company is good or bad.
But that opinion cannot be used to classify that object/action/company for every one it can only classify it for the individual holding that opinion.
I'm always amazed at who people think their view is the logical, informed one and that other people's views are ignorant and often crazy.
For the record, I've never served on a jury. In my country of birth I was never called to serve and in my current domicile I'm legally not allowed to serve. Does that mean I have no experience of my peers?
Wake up, you do not have all the questions, let alone all the answers. Things you hold as truth today you will hold as false tommorrow. Same for me.
Democracy is not about coming up with the right answer. It is about expressing the views of the people. Note, this does not mean the majority but all views.
Self selects? How? By letting the great unwashed vote or what other method do you favour? Based on blood line, or school or star sign. If you opt for the voting then the people you seem to look down on and despise still get to elect the officials, how is ths different from letting them serve instead of voting?
The current system elects old white rich guys, my idea would elect a wider spread of the population. Gender, religion, race would be expressed pretty much how they are in the population.
The current system spends money on defence and welfare at the expense of education and healthcare. Would such a deficit exist under my idea?
The current system encourages career politicans and the old boy network. My idea detroys this at a stroke.
So if 5% of the voters are Nazis why should they not have 5% of the goverment?
This is the question that lies at the heart of democracy. A representive goverment takes the good and bad from the society. That is what democracy is. It is not a select group of people choosing who is acceptable to govern.
All I want is to be ruled by my peers. The none of the above clause will just cause the politcos to be worse not better. We need to remove the career politician.
My way if you're eligable to vote your name is entered in a lottery if you win you get the job.
If you choose not to server your passport is revoked for your term, in effect you become a non-citizen, unable to travel etc.
For congress/senate there is a 25% turnover each year.
This system would elect a representitive cross cut of the US population.
If you do not want to be ruled by your peers is democracy whay you really want?
The mere fact of my valves appearing through my hood would cause me not to lable myslef as lucky. In fact decidely unlucky would spring to mind amongst other phrases
First and foremost, make sure you have your data backed up and secure. Nothing else matters if the data is missing. When did you last test your backups?
Next ensure you can get you backup data when you need it. You state colo I'm assuming you have a duplicate system at your colo. Can you get access at 22:15 on July 4th?
Now draw up your usual emergencies fire, flood, tornado, earthquake etc. Have a plan how to get your systems up and running. Do you need to rent office space? What about net conectivity.
Lastly, re-check your data backups, do you have everything, is it error free, do you have more than one copy. If you have the data your company can recover.

Take a look at LTSP.
In my mind LTSP is how Linux should go after the corporate desktop.
The client/server model is so costly as to be laughable. Ditch it and save money.
Look up pervasive computing. Start to think outside the stupid screen/keyboard paradigm. If you have the infrastructure then the apps will come.

Dome I'm just using it for DFD/ERD but it handles most diagrams I've ever heard of.

No data, no job, it's as simple as that.
