OK, I've done that too on a mainframe not the whole mainframe but a shared CICS region.
I was debugging a CICS/DB2 program using CEDF, and I knew that the problem was that a DB2 insert statement was returning -803 (Duplicate), so I wanted to overwrite the SQLCode with 0 (OK), after carefully stepping thru and getting to the right point in the program, I go to overwrite the SQLCode storage location with zeroes and *BAM* the CICS region goes down.
Damn now the whole team and I have to wait for the system programmers to start the CICS region up again.
CICS is up and I start my debug session again and a little while later at the crucial point *BAM* the CICS goes down again.
This time my phone rings... its the sysprog...
I felt like a complete twat.
Listen i've been doing serious spreadsheet programming back since lotus 123, and I know that learning to sort is not that difficult, even if you haven't learnt it before.
All you have to do is switch on the record macro function, and then click on the column that you want to sort, and then click on the sort button, and choose from ascending or descending.
See that was easy, 'Knuth said;)
As a South African, I would appreciate you not sending them here, I have enough of the crap / slow / broken-from-being-used-as-a-teething-ring things already.
Some of them have devolved from USB/Keyring to Keyring-that-I-can't-remember-whats-on-them.
Finally, I would not recommend the SATA drives as keyrings... especially if you're in the habit of throwing your keys on the glass side table immediately inside the front door.
This promotes cheap medicines.

No patent term extension can extend the term of a patent for a pharmaceutical beyond 14 years from the receipt of Food and Drug Administration approval to commence marketing....
The bottom line is that the period of marketing exclusivity provided by a patent for a pharmaceutical can never exceed 17 years
I bought a sinilar IBN Nodel N where the N key (N for Nother) is completely screwed, so I have been forced to substitute that character, luckily the control keys are okay, so I can cut and paste when I need to... ctrl-v... mmmwahaha
I remember having the ability to switch between different LPAR's on an IBM mainframe running MVS.
I didn't execute the switch before 1985, but I'm sure the capability would have existed before them.
I haven't had much joy from sun hardware.
We had a project that needed to process large amounts of data.
A fairly expensive sun server with CoolThreads technology was procured.
The application was deployed and the processing time was so bad that we started blaming it on the "CrawlThreads".
We redeployed the app onto a commodity HP server with CEntOS installed and the processing time dropped from 8 hours to 2 hours.
I dont actually think that CoolThreads was a bad technology, unfortunately the application was very limited to what it could do in terms of parallel processing. Most of the processing was linear, so the majority of the massive number of threads that were available from CoolThreads were sitting idle, and the trade-off for the great number of threads available was less processing power for each individual thread.
You are missing the point of a sunk cost.
If someone has a need and has to spend funds to meet the requirement by a certain date due to regulatory or other reasons, they will pay the costs or face the consequences.
Once paid this is a sunk cost, already spent and not assumed to be recoverable.
If later on someone else is able to benefit from the product of the sunk cost, that is a different argument, and possibly negotiations will proceed.
Negotiations wont necessarily result in recovering any of the initial sunk cost, there are many possible results, some of which may be collaborative development or shared future maintenance burdens.
I like the story about NASA spending millions of dollars designing a ballpoint pen that can work in zero gravity, whereas the russians opted to use a pencil.
Thrashing is a violent action such as causing a hard disk to spin fast and long. The effects are generally benign, i.e. there is no damage done when the thRashing stops.
Trashing causes long term damage, such as installing windows or.net
But apart from the semantic differences, I would say you're right on the money.
This comes down to choosing the right tool for the job. Perhaps their application is written using frameworks which enable/enforce this kind of normal transactional processing of requests.
Now if the existing application is the only way that they know how to get to the data, then it may easily become the golden-hammer / silver bullet that gets used for performing an upgrade, rather than writing an external sql script which they might not be familiar with. Add to this the common convention of "nothing touches my database except my application", which has proven to be useful by preventing rogue updates which cause application 'bugs', and the golden-hammer / silver bullet becomes even more appealing.
SQL script wouldn't be the only non-application choice, there are quite a few good ETL solutions available, however these tend to cost quite a bit and perhaps the vendor does not want to impose another licence fee onto the client.
This brings up a point more relevent to the main article thread, when deciding whether to throw people or hardware ata particular problem, you always have to be aware of the hidden costs i.e. licences for all software used including pre-requisites, network capacity, server-room capacity power & cooling etc.
Naturally wide-spread use of open source software makes the initial calculation of software licencing cost a lot easier, although I'm sure that there are those who could argue that the savings on open-source software licences are eroded by necessary additional staff costs.
I thought that it was named after the HMS Beagle upon which Darwin made his first observations that led to his theory of natural selection / evolution.
I also heard a story about our water sources being saturated with female hormones from birth control pills. The hormones do not break down, and were apparently found in arctic samples.
There is a large difference btw Free Software and Open Source... that Stallman chap has been ranting on about the differences for ages.
We use both at work, we pay for some of the nicest open source software that we use, namely jira and confluence from Atlassian. We pay the enterprise licence, and they give us access to a copy of the code. We also use CEntOS, mostly in the dev environments and RHEL in prod.
Databases in order of adoption:
Sybase ASE
Postgres, on a crappy server to get performance that Sybase couldn't deliver
Oracle because the new financials solution must run on it, probably cant run on others without a lot of work
Government oriented solutions such as the NHS and electronic voting examples given earlier, should be completely GPL, and make use of open standards to support maximum interoperability, this would allow development funded by the first world governments to be charitably donated to 3rd-world/emerging countries.
The governments should not be profit focussed, so this should not cause a conflict of interest.
Consultancies / companies and contractors that are hired to implement the vision should be made aware of this fact upfront and these conditions should be acceptable, as they are not being asked to donate their own brainchild, merely the fruits of their labour for which they should be remunerated fairly.
However, ethical difficulties may arise when a re-usable eureka component solution is discovered based on high-level vague requirements, but falls within scope of the overall program.
Custom written top-secret military programs however are clearly a different case, this software represents an advantage to the government over potential enemies, and as such should not be open-source and definately not GPL.
If the development is outsourced, one would expect the government to get the source and the vendor to destroy their copy once the contract is handed-over.
Within business, the advantage would need to be measured on a case by case basis, similar to normal build or buy evaluations. What is the business advantage offered by the particular software? Is it a core differentiator, or is it payroll? If it is non-core, then it should probably be acquired and preferably open-source, what are the available support options?
If an outsourced service is going to be used to fulfill the non-core function, then the Data Ownership needs special attention within the SLA with the service provider.
If it is a core function, that will directly impact differentiation within the market then source ownership is a crucial element and one would not want to pass this on to potential competitors.
Finally commodity cycles will probably catch-up with most market differentiation factors eventually, and what was once a core differentiator will become a norm and will probably be available as open source or as an outsourced service.

A company called MDI already has compressed air cars on the streets of Mexico city.... They actually make several cars and can get over 60mph...
Having sampled mexican cuisine in the past, i.e. chilli-con-carne and refried beans.
I have my suspicions how they achieved the souped-up power boost from 28MPH to 60MPH using compressed air.
If my suspicions are correct, the environmental freindliness would need to be reassessed.
The libraries that you have used have provided additional value that should be factored in... documentation, knowlegable community, database independence etc.
This has come at a cost of pushing you into a code structure in which you currently feel restricted.
What I like about Spring is that it acts as kind of an uber-Factory, so if hibernate is not working out for you, you should be able to refactor to another persistence mechanism fairly easily, because the implementation is hidden behind the service that is exposed by Spring.
You can then change the implementation using new frameworks, and as long as the signatures / interface dont change then the calling functions will be unaffected.
You may want to consider swapping your hibernate implementation for iBatis see Hibernate vs iBatis What I dont like about Spring, is that I find it sometimes difficult to piece together a decent mental model when first looking at an existing application from various bits of xml which may or may not have dependencies between one another.
The libraries that have been abstracted at a higher level e.g. Hibernate or iBatis as opposed to jdbc exist because add value by solving common issues.
They are successful because of the open communities that spread the knowledge outside of any single organisation.
Beware of the danger when writing your own, that you may end up at a later stage having to solve issues that have already been dealt with by existing frameworks.
Good Luck,
Neil.

If you don't have any values in your collection, then you know that you don't have a value.
