Union-Find by Ernest Crobberfield - Sat, 04 Jan 2014 21:55:56 EST ID:DSv7yEq1 No.30678 Ignore Report Reply Quick Reply

So, I need to program a Union-Find algorithm in Java which reads the pixels off a 800x600 .bmp bitmap file which includes only white and black pixels, and find the biggest connected area of white pixels.

I know how to read the pixels (for inside a for) and to determine if they are black or white. However I'm not sure how I should do the algorithm itself.

So far I have written a method which reads the picture row by row from top to bottom, left to right, and saves the information whether a pixel is black or white into a int[800][600] array. I also wrote a method which can determines if the neighbouring pixels are black or white.

What should I do next? Am I doing something wrong?

So this is what I wrote so far (sorry for comment language, but it should be pretty straightforward): http://pastebin.com/wU3PkBCj
connectedComponentIndex is basically the amount of connectedComponent entities found so far.

If you need something explained better, lemme know.

You start with a map where each element maps to itself, making them singleton trees. When you connect two elements in union-find, you update the map so that one of the elements maps to the other.

I assume you can do it by creating your own tree-structure, but my java skills are too rusty to help you there. As a C programmer I'd need pointers.

I managed to program the data structure itself, but I somehow have to make it so that I can expand the size of the datastructure as I go through the main program. So the size can't be static. How do I do this?

Instead of a static array use some dynamic builtin datastructure, google suggest ArrayList for me.

Unless you are going to actually use the rank for optimizing the tree (which I assume is not going to be a requirement, I'd suggest you drop it, otherwise it's quite clear to the course staff to see you are copy pasting code. Also you're flattening the tree in find incorrectly.

Form personal connections with your clients.
Find clients who value being able to shake hands with a contractor over the table rather than Skyping with some random Indonesian dude.
Do top quality work, deliver on time and stay within your quoted budget.
As you do great work, it will add to your portfolio, allowing you access to better clients and the ability to charge higher rates.
Approach potential clients directly if you need work, rather than waiting for leads.

If a client wants a lowest bidder from India, they're not looking for the product and advantages you bring to the table; you're out of their league. Learn to recognize and avoid those clients early, they'll expect you to bend over backwards for 50c/hour.

>Form personal connections with your clients.

This is a big one for me. I have a full-time design/development job so I don't actively look for freelancing work; it usually falls into my lap via word-of-mouth from people I've worked with in the past. However, because the client is a personal connection (or one degree away from one) I find greater motivation to communicate clear expectations (timelines, cost, etc.) and deliver quality work than I would if the client was some dime-a-dozen small business looking for the cheapest logo possible.

>>30670 is right on, too, in saying that those are the sort of clients you do not want padding your portfolio with one-off projects that you did on a weekend for the bare minimum amount.

Plus, a good working relationship with clients you are personally associated with usually (but not always) means repeat business. I've had one for like ~4 years running.

I'm writing a program to manage sets of images and rotate through them as desktop backgrounds since the default manager in Windows is pretty limited. On Windows it seems the only way to do this is with .NET, so I'm writing in C#.

The actual call to change the current wallpaper is pretty straightforward but I've been thinking about how I might customize the transitions. Does anyone know if it's possible to have transitions between images other than the default Aero fade in/out or just an instant update with Aero disabled?

Maybe I could disable Aero transitions and then edit and update the wallpaper.bmp file fast enough so that it changes bit by bit (figuratively) from one source image to the next, but could the desktop background itself update fast enough and often enough (like what, 30 times a second?) to sustain the illusion? Probably not...

If not I guess I'll just stick with what I have now, Google hasn't given me much and I don't know how much effort that feature would be worth anyway.

I've barely started looking into programming and coding and such, but I'm starting with basic stuff, I would think. I'm trying to customize my firefox through userchrome and I've got some success but still am retarded.

I'm trying to change my tab sizes, and what I have doesn't work. I don't know if there's anything I need to do for the little icons on the tabs, the text on the tabs, or the small little indention on the very left of the first tab.

/* change the tab tooblar height */
.tabbrowser-tab {
height: 12px !important;
padding-right: 4px !important;
}
.tabbrowser-strip {

That's what I've got right now for tab sizing. Tried asking 4spam but it seems broken right now.

I am trying to learn cobol. (no job/school reason; I just wanna) in fact, I want to learn the fixed sourcecode style that is AGGRAVATING ME SO.

I'm on a mac (mavericks/10.9.1) and I somehow managed to compile open-cobol 1.1.0 and have it compile some of the time. my problem is with the rest of the time. I can copy verbatim an example program known to work and it WILL NOT WORK, IT ANGERS ME. does anyone have experience with open-cobol or have any ideas to help a newber try to just get the damn compiler to work for me? I've barely even had a chance yet to learn the basics! :('' my main question is how do I tackle quirks of open-cobol or is there something novices are likely to do wrong (because I'm likely doing it)?

I can only guess that it's an EBDIC/ASCII problem, but I'm using a text editor that should be saving text entirely as ASCII, and it's running through the text editor before compiling even when it's an example program that does compile. besides: why is open-cobol set to ebdic when I'm on an ascii machine/how do I change it if that's the problem?

I'm building a classifieds website using Rails 3. I'm a complete novice, but I'm trying to develop a general template with as much basic functionality as possible, and then pay someone to finish it up to market level.

How much should it cost to hire somebody? My site is fairly basic, I need ActiveMerchant, a pay for posting mechanism, post destruction countdown, track usage statistics, and a cached search/sort field (1 dynamic search and several automatically updating, cached searches based on supplied criteria).

Upon satisfactory completion of the above, I may be offering a site maintenance job, which could become regular steady pay depending on traffic.

I've looked on several advice sites, and honestly the pricing guides/schemes sound like a total ripoff. One site lists a contact form as being the equivalent of four hours of work, when I'm pretty sure I just did that in 5 seconds generating a new scaffold.


Since I will foreseeably be working a low paying job to fund this endeavor, and given the relatively simple design standards I am expecting, in your honest opinions is it worth it to hire someone to complete the job, or should I hack it myself in the hopes of producing an inherently flawed yet market ready site?

How much should something like this cost? If it's too high, I won't be able to make enough money to pay for it, and would have to DIY.

These statements are very misleading. That might work for Ruby, but it won't work with every language.

Programming languages are more than syntax. They're also standard libraries, idioms, and runtime environments, and being able to program well in that language means learning that stuff in addition to the syntax. Some languages (looking at you, C++) are sufficiently complicated that you need years of practice before you can really write production code in them and be confident that you're not going to fuck it up. Not to mention that some languages require picking up entirely new ways of thinking about a problem.

Well, nobody understands C++ completely. There was a panel a few month's back on what is the "fastest" language. Everybody admitted that nobody really understands C++ even Bjarne Stroustrup claims he hasn't found the limits of what C++ can do. The guy who coded Betfair in C++ for a dozen years and then switched to Java VM and coded a completely new architecture to handle the amount of trades admitted he doesn't even fully understand C++ either but doesn't stop him from using it.

That said you can read SICP and then start doing C++ the basics are the same. Will you be a master of C++ no but you'll be prepared to do any language because SICP gives you a masterclass in everything you need to start with. You get a solid overview of what OOP is. I wrote a trading program on a FPGA after doing SICP in C++ and reading Accelerated C++ book to learn syntax/libraries, and taking MIT's 6.004 Computation structures course. SICP is all you need to learn programming period.

I have been working at an office job doing data entry. I have been automating most of my work through Excel VBA. Mainly auto formatting and auditing reports and then making click-bots when given a spreadsheet to enter into some web based interface.

The click-bots are a gigantic pain in the ass because of the limitations of the editor and the language. No Delegates, saving everything to PERSONAL.XLSB etc.

So I am going to get up and ask the IT department to allow me to use another language to make my click-bots. And un-websense me I feel like this is a one shot chance so I want a good reason to choose my language.

Right now I am looking at Ruby or just Visual Basic. I need a language that is easy to learn and simple enough that I can shit out something quickly if I am under the gun but I can later refactor into a more reusable tool. It also needs to be able to access the document model of a web browser, and well. The most recent website was entirely Java built and not a single HTML element had an ID.

I would like it to also be able to read and write to Excel sheets (VB), but I can do without for just click bots. I would also like it to be cross platform (ruby) so I could use the language elsewhere and not just for this one job.

I've been trying to make a delay insensitive carry lookahead adder but It's getting gigantic. I've been using DIMS (pic related) to directly create the small circuits I need to compose the more complex ones but a single carry look ahead unit uses 2 OR gates and 1 AND gate, costing 12 C-gates of area. Making them directly out of C-gates would cost 16 3-input C-gates.
I've looked for alternatives designs for asynchronous circuits but the only one I can find is Null Convention Logic which uses threshold gates. Does anybody have any learning material on what transformations you can perform on NCL circuits or any other alternatives that are delay insensitive?
