This is essentially 'Experimental Mathematics' at its best - the conclusions are (I assume) valid, but no theoretical framework is provided to show that there are no other solutions. I think their work is very important, but it lacks mathematical elegance; it may be that we will never find a practical and elegant mathematical theory to cover this - I hope I am wrong!
I know of no proof that determines if the number of solutions (disregarding symmetries and topological invariant transformations,,,) is finite or not.
Looking at the method of how the new ones were found, I suspect that there are an infinite number of (disregarding symmetries and topological invariant transformations,,,).
Simply because you do not understand something, does not make it of no value.
Saying what you said suggests that you are stupid.
Sorting things by date, or datetime, may not be of direct interest to many people, that is also fine.
Most people are not aware of using Linux, but that does not mean that it is unimportant in their day to day lives. For example they may have an Android phone, have an eBook reader, use the Internet, or...
datetime order makes it easier to find what are the latest files to be produced, also I can compare the latest with the earliest without having to look at almost every file to find the right ones.
Note that the use of 24 hour notation removes the need for sill am/pm indicators

So my first paragraph applies - especially when one is very tired.
Initially, I was only going to comment along the lines of my second paragraph - but I felt that would come across as too harsh & likely to provoke irritation/anger!
Usually when I try to install software and it fails, I've made one or more mistakes myself! To makes matters worse, I'm not always aware of what I did wrong.
If installing LIbreOffice, or any other open source software, fails and you have not made any mistakes that you are aware of - then I advise you to file a bug report.
I am a software developer, and I know from my own experience, that any moderately complicated piece of software always has bugs - no matter how thoroughly you think you have tested it!
I moved to xfce as the best alternative to GNOME 3 in Fedora 16 - now for Fedora 17, I'm moving to mate.
Mate has restored some of the useful functionality of nautius that was dropped from GNOME 2.
GNOME 3, Unity, Metro, etc. - are all indications that some designers think fashion trumps functionality (Designer: "Don't worry your tiny little mind Sweetie, we know best!").
-iname pattern
Like -name, but the match is case insensitive. For example, the
patterns `fo*' and `F??' match the file names `Foo', `FOO',
`foo', `fOo', etc. The pattern `*foo*` will also match a file
called '.foobar'.
[...]
-ipath pattern
Like -path. but the match is case insensitive.
-iregex pattern
Like -regex, but the match is case insensitive.
My first mobile phone allowed me to delete games, pictures, and menu items I did not need.
My current mobile phone offers the choice of 2 distracting images for the home page, with no option to make it plain. The menu is a 3 by 3 array of icons for different features - I would like to delete all except 3, and to chose the default. I would also like to control how long it rings when a call comes in. I would be quite happy if it did not have a radio or a torch - features I never use.
I am simple minded, I like simple things. I already have enough complexity in my job as a software architect & lead programmer, I don't like spurious unneeded complexity forced upon me...
To be able to do things on the command line with a Linux phone would be great, I don't need in-your-face array of icons on a home page - I like your idea. Where can I get one one???
I really wish your idea was viable - a challenge for some company, perhaps?
Also, note that any product starting with an 'i', such as an iPad, indicates that it relies on the imagination of the purchaser to see more value in the product than the price warrants. Remember 'i' stands for the square root of minus one - an imaginary number!
As I said to a friend, who is also an experienced developer, I wish I was good enough to send Linus a patch and get him to insult me, I would be chuffed - even better if it was accepted! My friend agreed with me. However, neither of us are in that line of work.
I have a high respect for the kernel developers - not only for the tremendous skills, but also the immense care they need to take in minimising the chances of bugs.
In any development, I respect people a lot more when they own up to the inevitable mistakes they make.
I would not want to be anywhere near the supposed flight path of a Microsoft Rocket! - let alone be anywhere near the launch pad.
An Apple Rocket would be much worse, nowhere on Earth would be safe - as they would be using Apple Maps! However, Apple Rockets would be much more elegant and fashionable - which of course is much more important than safety...
Both companies would have huge PR and Marketing budgets extolling their 'reliability' and 'safety' record - even before their first launch.

In New Zealand illegal methods where used to obtain evidence in the Kim dot com case - and totally innocent people can't get at their own data - thanks to the US government & the media mafia.
As for PostgreSQL, that is my favourite database - I've also used MySQL, Oracle, and several other databases .
If you are serious about using a free database and value your data, consider PostgreSQL - as it outperforms MySQL and PostgreSQL is much more reliable.
Plus instead of a few hours (if you are lucky) upgrading every 4 or 5 years, you now have to upgrade every year? Not to mention the time spent testing and replacing application software that you find is not sufficiently compatible with the upgrade.
Even if Microsoft O/S upgrades where not charged for, it would still cost extra in terms of the time involved in upgrading. Costs include not only the cost of labour, but also lost opportunity costs due to that individual not being able to do something productive.
For one open source product I opened 4 bug reports, all got fixed - 3 within a week, one took over month because it was more secure.
I raised a Linux kernel bug, it got fixed within 48 hours.
With a proprietary software, apart from the initial cost, best of luck getting a bug fixed unless you pay them - getting a patch just for you won't be cheap, otherwise you wait until the new version comes out (with a fresh lot of bugs).
With open source software, you can pay people to do fixes for bugs that not so important for others.
In short, with open source software you often get better support for a lower budget than you would with proprietary software. Also, if the product is something you rely on for your business's survival, and the product is discontinued, you have the source code to pay others to maintain and enhance - but with proprietary software, you are dead.
Note that Linux is open source software, it is found everywhere from mobile devices (smart phones, eBooks,...) up to supercomputers. Linux is used on more devices than any other operating system. Major companies like Red Hat and IBM help support it along with unpaid volunteers.
There are many, many, proprietary products that have been abandoned. A company that relies on a proprietary product is acting irresponsibly, they have no assurance that it will maintained in the way they need it to be - it could be abandoned, or change in ways that make it no longer fit for the purpose it was initially obtained (PS3 & Linux support).
Not to mention that security is generally better for open source software than for proprietary products.

Yeah, right on man!

MySQL is far less ACIDic than postgresql!!!
You forgot:

* here 'local' refers to American Media, which by their definition means: wherever you live, regardless of country

A company that relies on a proprietary product is acting irresponsibly, they have no assurance that it will maintained in the way they need it to be - it could be abandoned, or change in ways that make it no longer fit for the purpose it was initially obtained (PS3 & Linux support).
Not to mention that security is generally better for open source software than for proprietary products.
