Can we get Printer information such as mono or color from its Make and Model Number .
Is there any naming convention exists ?
For the model like Lexmark,Canon,Toshiba,HP is there any naming convention exist ?
Any help will be appreciated
Thanks in Advance
From a quick look, Lexmark at least doesn't seem to include the color information on their printer models - M* is probably mono, T* is probably mono, C* is probably color, but X* can be either.
It's probably best, when writing descriptions of the printers on your network, to include the desired information. ("Color inkjet in the lobby of building A").

I want to parse text files with lucene using HunspellStemmer to check for spelling errors. I will use Hunspell dictionaries that's why I want to use HunspellStemmer.
At this point I'm not sure how I should parse the files and do the checking.
Could I use a Standard Analyser with WordFilter to index the text in a file and check Term by term if the keyword is present in HunspellDictionary.
I did that and it works, not sure it's the optimal solution, but if I want to output 3-5 suggestions by word not present, I have no idea what do to.
I could use a IndexerSearch when I use a PlainTextDictionnary, but no idea how to get that functionality with HunspellDictionary. (it doesn't implement Dictionary).
any help will be really appreciate.
thanks
examples that I want to check : hell, hello, hall, helli. I'm hoping to have suggestions for "helli" using a Hunspell.
I have a project on color profile conversion in C++, where the idea is to use CIELAB as transition between RGB and all others (CMY; CMYK; HSV; HSL;...).But I have one big big problem. I have searched everywhere and I cannot find any formula or descrition how could I convert CIELAB to others(CMY; CMYK; HSV; HSL; ...) only I got is what I found here : http://www.easyrgb.com/index.php?X=MATH&H=14#text14 . Can someone please help me with formula or with an idea how to get to them? Thank you so so much.

Color conversion with mathematical formulas yields very poor results with no serious application. Color systems are far too complex to capture them in simple, closed mathematical formulas let alone in linear formulas.
Good results can only be achived by using color profile files. And the conversion basically invovles interpolation between samples stored in these files.
Have a look at Little CMS. It probably does everything you need. Or if your software will run on Windows, you can use the built-in Windows Color System to do the conversion.
I know this is pretty much a stupid question. I know almost nothing about how compiler really works.
But recently I want find what symbol name does the compiler generate for my ivar, my methods.
Where and how can I know the answer? (I have only used some IDEs. So if the solution is better to be simple . And it would be great help if the instructions you provide is really explicit)
(By the way,is there any reference that i can learn about the things like this?)
PS.I'm IOS developer.And if gcc and LLVM works different answer on this question , I would like to know both.
You can use nm to dump the content of a binary object. Then, each compiler has its own way of mangling. I suggest you have a look at Name mangling for objective C in wikipedia, it will help you understand how mangling works.
Surely GCC and Clang must have compatible name-mangling schemes, since they can use each other's code.
If you are using XCode 3 select a source file and then pick "Show Assembly Code" from the Build menu.
Apparently XCode 4 users do not need assembly code :-(
Out of curiosity, what may the rationale behind these function names (found in Apple's Quartz Core framework) be?
ZN2CA11Transaction17observer_callbackEP19__CFRunLoopObservermPv()
ZNK2CA6Render9Animation9next_timeEdRd()
ZN2CA11GenericRectIiE5insetEii()
Do you think the developers somehow encoded argument types in function names? How do you find yourself putting "EP19" in there in the course of day-to-day coding? In what circumstances do such barely readable function names actually help you read code and otherwise be more productive?
Thanks in advance for any hints, and Merry Christmas!
These 'mangled' names are automatically generated by the C++ compiler and indeed encode type information.
The project I am currently working on requires a lot of hexadecimal numbers to be entered into the code.
I once saw a pic of an old keyboard with a hexadecimal numpad (has A-F letters on it also) replacing the normal numpad. Anyone know where I can get one of these?
IPv6 Buddy -keypad should work well for hexadecimal input.

If you can get your hands on one of the retired space shuttles, they have one!
I have an old Heathkit learning toy with a hex numpad because the only way to program it was to assemble code by hand (it came with a 6800 manual and some notepads) into the online monitor. This was actually fun!
Mine is missing the 'D' button however.
Great idea with the programmable keypad. I think i am going to pick up one of these: DX1 input system. Works for any reconfiguring I might want to do.
Is this the one you're talking about?

While this has a lot of "gee whiz" appeal, I have to say:
You have two hands. Use them. A-F are all reachable with the left hand on a standard keyboard while your right hand is on the num-pad. Instead of putting muscle-memory time into some arcane Hex-pad, you'll be learning to touch-type with your left hand, which has application outside your current project.
Better yet, come up with a smarter way of getting the hex codes into your code. Write a script that extracts them from your data-source and into your code as symbolic variables... or whatever.
EDIT
Ok, I'll give you the benefit of the doubt. Lets assume you're working on a hardware project and need to provide a specialized interface for your user. Maybe a programmable keypad would fit the bill?
Not sure of the specifics right now, but I'm pretty sure you can easily write a keyboard remapper. You could remap the QWASDF keys to ABCDEF in order to type them more quickly. That way you could use 2 hands to type. Or if you are in control of the program they are being typed into, you could just translate the keys in code on the fly.
