I have a series of pictures from some old documents which I want to digitize them and convert them to excel file or other things like this.what is the best way to do this?
Depending on the pictures you are using, you might want to consider looking into a toolkit that supports both scanning in images and OCRing them such as the LEADTOOLS Document SDK, which has TWAIN and WIA scanning features for scanning in the document images as well as OCR features can be used to convert images into document formats. As I work with the vendor of this toolkit, I can suggest a number of approaches to improve OCR recognition of the text in your images, if this is indeed something that is suitable for you.
But without knowing more details, it is difficult to give a precise answer for what you need. You should provide more information when posting a question like this. For example, describing the input pictures in more details, giving examples on what exactly they are and how do you expect to handle them, as well as elaborating on the outline of the final Excel output you are seeking.

I am interested in writing my own Shapefile translator. It should be able to read the Shapefile and draw the resultant shape.
Does anyone know how to do this? I am not interested in any sort of API or SDK. I will also be using Objective-C to do it.
Also, are there any alternatives to Shapefiles?
UPDATE
As an alternative to Shapefiles, use SVG maps. There are some really great free ones here.
Shapefiles were created by ESRI and are pretty common throughout the GIS world. There's many different ways to store GIS data though, KML, GML, GeoDatabase, Spatialite file, etc.
Here's a link to shapefile specification. It's pretty straightforward.
I need to put together a team to build a silverlight based application that will read an xml file and generate a Mind Map diagram based on that file.
I am new to silverlight and I need to find out what skills do I need and how difficult is it to do something like this.
I expect the typical Mind Map features available in a commercial Mind Map software, like the ability to open and collapse nodes and to move the nodes around the screen.
There is a pretty well known Silverlight implementation here: http://code.msdn.microsoft.com/SilverlightMindMap
Might get you on your way to assess what is required.

I'm maintaining a site that has thousands of images that have not been compressed nearly enough. The homepage weighs in at 1.5 Mb currently, and it could easily be way less that half that.
I'm looking for some kind of tool that'll take a folder full of JPG pictures and will recompress them to their "optimal" compression value.
Obviously, "optimal lossy compression setting" is an oxymoron, but I'm thinking maybe a tool that'll try different levels and compare the outputs to the input, and choose a "sweet spot" between size and destruction?
Or even try whether PNG is a better option, many times it is, for "drawing" type stuff.
Does anyone of you know any such tool?
I'd have lots of fun coding one, but I bet someone already did and will save me 2 days.
Alternatively, of course, anything that'll take all pictures in a folder and recompress them with a fixed quality level (say, 40) will also work, it'll just not make my inner nerd as happy, but it'll solve my problem just fine.
(Ideally something that can run on Windows, ideally from the command line)
Thank you!
I used ImageMagick for that purpose. It consist of a lot of things, among which a set of commandline tools that can be used to chain image operations along each other.
It is fun to experiment on the commandline, copy it in a script and let it rip over a couple thousand images. I found the default quality of the resulting images also pretty good.
Here is the website. I used it under Linux, but I saw there is a windows version too.
If you are looking for a non-programming approach (kind of the wrong idea here on SO...) you could try IrfanView's batch feature. It's a lightweight image editor that will let you batch convert images based on a few simple criteria (such as file dimensions, etc.)
For optimizing png's, pngout is king
http://icompressor.blogspot.in/ Mass Image Compressor does the job of doing compression of all the images in single folder. It doesn't have command line arg or intelligent mechanism to automatically decide compression levels but it provides you a sample compression to give you feel of compression based on compression parameters that you have set.
In the past I faced this problem, and found a way to compress JPEG images. This answer cannot help you compress PNG or other formats, but JPEG.
I found that Windows XP's MS Paint app is wonderful for this purpose. It compresses a JPEG image very nicely without any visible loss. So, I wrote a utility to mass compress the files. Here is the link: AutoSavePaint 1.7.0.2
It has helped few a people since it was published. I hope it helps you too! :)
What I need is a method to display a graph of data from a tab delimited file uploaded to a website. Once the file is uploaded the program will convert the data to a graph or the graph be generated locally and sent to website, but it needs to be automated and in realtime.
Thanks,

Your question is rather broad.
The answers to these questions usually depend upon what sort of programming framework you will be using for your website. For example, PHP has some native libraries to generate graphs based on submitted data in multiple formats. But that may not be what you are looking for and using something like dojo or ExtJS might be better. Or if you are a Java/JSP person, then there are lots of frameworks that can handle this. Of course .NET might be better. I am sure the Python and Ruby folks have their own thoughts as well and then of course there is Delphi.
Our application needs to be able to render barcodes to PDF documents that will be accessible over the internet. Our technology stack includes SQL Server Reporting Services so we would like to leverage it and its ability to render to PDF; however, we are not able to get it to embed the FREE3OF9.ttf barcode font in any consistent manner.
I have reviewed this question, but would like to know any if any one has used Neodynamic products, particularly their SSRS product and whether or not they were satisfied with it. If anyone has any other solutions besides Neodynamic for rendering barcodes to a PDF via SSRS I would also like to hear those.
I haven't used SRSS before, but I have written barcode generating software. If you are looking for alternatives, writing your own is not too difficult.
You can find all of the information regarding barcode encoding online. I used Code 128, and simply created a table of values in my source code. Rendering the barcode is just a matter of drawing solid black and white bars based on the information in the table, so you don't need to worry about embedding fonts.
It looks like you want to use Reporting Services, so maybe this doesn't help. Either way, good luck with it!
I use it at work and like it, it is very easy to use and has many different bar code options. I recently created a bar code our of an image outline, it was pretty cool. The Tool is easy to use its pretty much like adding an image to the report, you choose which field to populate the bar code, choose the bar code style and boom you're done.
