  • Could a truly random number be generated using pings to psuedo-randomly selected IP addresses?

    - by _ande_turner_
    The question posed came about during a 2nd Year Comp Science lecture while discussing the impossibility of generating numbers in a deterministic computational device. This was the only suggestion which didn't depend on non-commodity-class hardware. Subsequently nobody would put their reputation on the line to argue definitively for or against it. Anyone care to make a stand for or against. If so, how about a mention as to a possible implementation?

  • Jquery ui slide content along with scroll bar

    - by Linas
    Well i'm totaly lost here, i am using jquery ui sliderwidget to make this quite simple menu but i just can't figure out a basic formula to make menu items slide along with with scroll bar. Here is jsfiddle: http://jsfiddle.net/n2H6Q/4/ Please keep in mind that content height can change to any value that's why i have use random height, and container height can as well change to any value, that's why it is so difficult for me to figure out how to deal with all these numbers... Any kind of help would be very much appreciated.

  • How to avoid repetition when working with primitive types?

    - by I82Much
    I have the need to perform algorithms on various primitive types; the algorithm is essentially the same with the exception of which type the variables are. So for instance, /** * Determine if <code>value</code> is the bitwise OR of elements of <code>validValues</code> array. * For instance, our valid choices are 0001, 0010, and 1000. * We are given a value of 1001. This is valid because it can be made from * ORing together 0001 and 1000. * On the other hand, if we are given a value of 1111, this is invalid because * you cannot turn on the second bit from left by ORing together those 3 * valid values. */ public static boolean isValid(long value, long[] validValues) { for (long validOption : validValues) { value &= ~validOption; } return value != 0; } public static boolean isValid(int value, int[] validValues) { for (int validOption : validValues) { value &= ~validOption; } return value != 0; } How can I avoid this repetition? I know there's no way to genericize primitive arrays, so my hands seem tied. I have instances of primitive arrays and not boxed arrays of say Number objects, so I do not want to go that route either. I know there are a lot of questions about primitives with respect to arrays, autoboxing, etc., but I haven't seen it formulated in quite this way, and I haven't seen a decisive answer on how to interact with these arrays. I suppose I could do something like: public static<E extends Number> boolean isValid(E value, List<E> numbers) { long theValue = value.longValue(); for (Number validOption : numbers) { theValue &= ~validOption.longValue(); } return theValue != 0; } and then public static boolean isValid(long value, long[] validValues) { return isValid(value, Arrays.asList(ArrayUtils.toObject(validValues))); } public static boolean isValid(int value, int[] validValues) { return isValid(value, Arrays.asList(ArrayUtils.toObject(validValues))); } Is that really much better though? Any thoughts in this matter would be appreciated.

  • iteratively creating graphs

    - by Andrei
    I have a bunch of files containing x and y coordinates, representing time and value (space-separated, but can be amended) For example: 15:06:59 0.0140 ....... I want to create a word file (or some equivalent) to show all these graphs. Right now I am using Excel. It pretty daunting task, as I ahve to plug paste numbers in two rows for each graph, and I have many of them. Thanks

  • One hour difference in Python

    - by Joel
    Hello, I have a datetime.datetime property var. I would like to know if it is less than one hour of the current time. Something like var.hour<datetime.datetime.today().hour - 1 Problem with the above syntax is that datetime.datetime.today().hour returns a number such as "10" and it is not really a date comparation but more of a numbers comparation. What is the correct syntax? Thanks! Joel

  • How to update a collection based on another collection in MongoDB?

    - by Sean Zhu
    Now I get two collections: coll01 and coll02. And the structure of coll01 is like this: { id: 01, name: "xxx", age: 30 } and the structure of coll02 is like: { id: 01, name: "XYZ" gender: "male" } The two id fields in the both collection are indices. And the numbers of documents in these two collections are same. And what I want to do in traditional SQL is : update coll01, coll02 set coll01.name = coll02.name where coll01.id = coll02.id

  • JQuery Cycle Plugin hover when paused issue, activeSlide

    - by user202141
    Almost all is dialed in except then I click the pause/play button, the current activeSlide div doesn't fade in on rollover like the other slides do. Bit at a loss to figure out why it's not allowing hover even though it works when the cycle is not manually paused (i.e. when just rolling over the pager numbers). Thanks for any guidance! http://www.xtracycle.com/home-test-a-rooney

  • Searching through large data set

    - by calccrypto
    how would i search through a list with ~5 mil 128bit (or 256, depending on how you look at it) strings quickly and find the duplicates (in python)? i can turn the strings into numbers, but i don't think that's going to help much. since i haven't learned much information theory, is there anything about this in information theory? and since these are hashes already, there's no point in hashing them again

    - by sea_1987
    Hi There, I have a field in my database that contain comma seperated values these values are numbers, and I am trying to do a search and count the number of times that a number appears in that column throughout the column, $sql = "SELECT sector_id_csv, COUNT(sector_id_csv) as count FROM cv WHERE sector_id_csv LIKE '$sectorId'"; This seems slow and does not return any results, and I know the sector_id it is search exsists in the table.
