I would have thought the unit was ABC in this particular case.

1010
But don't ask me for the one after that

1111111111 is the one after. The original numbers are "10" is bases 10 to 3, so the next two are 10 in bases 2 and 1.

Nope: 1 is not a valid digit for a number (theoretically) based on 1, only 0 would be. Therefore 1 is not a valid number base.
Of course, you could continue at -2, -3, and so on.  E. g. for the base -2, the representation of 10 (decimal) would be 11110 ( 1*(-2)^4 + 1*(-2)^3 + 1*(-2)^2 + 1*(-2)^1 + 0*(-2)^0 )

The Unary Numeral System is not base 1. Position does not determine value. It's not really even a numeral system.
|
|
|
|
|
Unary is not base 1, but base 1 is a unary system so the point is still valid.
|
|

Not really, as base 1 is, of course, logically impossible as mod 1, mod 1(1), mod 1(1(1)) etc. always return zero. Any attempt to represent a number in base 1 therefore produces an infinite series of 0 which means that it represents all values as equal and therefore fails to be a numeral system at all. In the sequence given therefore there is no entry which can possibly represent 10 in base 1.

No, base 1 just means there can only be 1 of something before it moves to the next level of units. So 1 is 1, 2 is 11, 3 is 111 and so on. Of course the "1" is arbitrary, you could choose "0" and say that 1 is 0, 2 is 00, 3 is 000 and so on.

No it isn't. You've forgotten that in any base b if there is b of any column value then you move to the next column to the left add 1 there and subtract b from the original column. In the tally system you do neither of these things so it cannot be a standard based numeral system, by definition. For further proof follow the procedure through ....
So counting in binary for example.
1 is 1 and all alone and ever more shall be so = 1
2 is 2 many for the rightmost column so we add 1 to the 2 column and enter 0 in the unit column = 10
3 is too many for the rightmost column so we take 2 to the 2 column and add 1 there and subtract the two from the unit column = 11
4 is too many for the rightmost column so we take 2 to the 2 column and add 1 there and subtract 2 from the unit column but that leaves 2 which is too many for the unit column so we take another 2 to the 2 column and add 1 there and subtract 2 from the unit column leaving 0. But now we have 2 in the 2 column which is too many so we take it to the 4 column and add 1 there and subtract 2 from the 2 column = 100
Now let's try that in unary ...
1 is .... too many for the first column so we take it to the 1^2 column and enter 0 in the unit column but it's also too many for the 1^2 column so we take it to the 1^3 column and subtract it from the 1^2 column leaving 0 but then it's also too big for the 1^3 column so ....
Like I said, whatever number you try to represent will always end up being an infinite series of 0s, in other words 0. So 1 > 0, 12 > 0, 3333 > 0. Not a numeral system.

Well I'm a programmer, not a mathematician. Proper mathematicians all agree how base 1 works so that's good enough for me. It might not fit your definition of what makes a base (you're forgetting that the "1" is symbolic, it doesn't mean "one unit greater than zero", so consider 3 in base 1 to be "xxx" and run that through your definition of base), but it fits my definition, and the definition of actual mathematicians so that's good enough for me.

Actually it is infinity as the only two valid numbers in base one is 0 and infinity.

I suspect the answer is in some shifty bits:
1011
1100
1101
1110
10100
10110
1100101
But, before I get a migraine trying to figure out where/what the last number derives from: I'd enjoy your answer 
cheers, Bill

The first response was right - 1010:
1010 == 119 == 128 == 137 == 146 == 205 == 224 == 1013 == 10102

Well, technically "ten" would have been right, too. You only asked for the next number, not the proper representation

I have a family member who is at the start of an important new government project that will involve a Windows application. One of the consultants is advising them to base the new project on Delphi. I am strongly in favor of Visual Studio.
I was wondering how experts on this forum feel about Delphi versus VS?
Please let us know your preferences. Thanks!

Delphi is too expensive for me, and support seems edgy, I would stick with your idea and use Visual Studio If it were 2003 or 2005 sure, use Delphi, but I would stick with VS. Also, Delphi docs suck.

Consider the company, the resources, the community, and the masses and masses of code and support available to .NET developers. Compare to Delphi.

I do not like anything by Embarcadero, and have always had more trouble with their products then with Microsoft, even when Borland owned the line before Embarcadero.
I would use C# and Visual Studio, personally.
Delphi, is a language. Visual Studio is an IDE, not a language.

I thought Delphi was a platform and Object Pascal the language.

Well, that's a tricky situation. Originally, Delphi (the platform) used Object Pascal, but then Borland began evolving the language and it became Delphi. There were some minor syntax deviations initially, but now there are all kinds of extensions (e.g. generics, anonymous methods) that exist in Delphi that aren't in Object Pascal. If you want more information or just want to get even more confused, head on over to the Object Pascal wikipedia page[^].
