  • How do I compare between ByteString and ByteSymbol in squeak?

    - by Guy
    Hi, I want to execute the following code: methodName := thisContext sender method selector. aClass selectors do: [:current | current == methodName ifTrue: aBlock]. Although the strings are equal, it never steps into the "ifTrue", I've tried converting both of them to ByteArray\String and it steel didn't work. Any ideas of how to compare them so I will get to the "ifTrue"? Thanks in advance

  • OCaml: Currying without defined values

    - by nicotine
    I have two functions f and g and I am trying to return f(g(x)) but I do not know the value of x and I am not really sure how to go about this. A more concrete example: if I have functions f = x + 1 and g = x * 2 and I am trying to return f(g(x)) I should get a function equal to (x*2) + 1

  • Compare equality of char[] in C

    - by rksprst
    I have two variables: char charTime[] = "TIME"; char buf[] = "SOMETHINGELSE"; I want to check if these two are equal... using charTime == buf doesn't work. What should I use, and can someone explain why using == doesn't work? Would this action be different in C and C++?

  • Javascript iFrame Limitations

    - by Matrym
    I know that, for security reasons, javascript can't read the contents of an iframe if it belongs to a different domain. This makes sense, given that the entire page could be an iframe with snooping scripts outside of the frame. The question is - are there equal limitations in the other direction? Can javascript within an iframe (from a different domain) read and manipulate the dom in its parent window? Thanks!

  • How to calculate next Friday at 3am?

    - by Mark
    How can you calculate the following Friday at 3am as a datetime object? Clarification: i.e., the calculated date should always be greater than 7 days away, and less than or equal to 14. Going with a slightly modified version of Mark's solution: def next_weekday(dt=datetime.datetime.now(), time_of_day=datetime.time(hour=3), day_of_week=4): dt += datetime.timedelta(days=7) if dt.time() < time_of_day: dt = dt.combine(dt.date(), time_of_day) else: dt = dt.combine(dt.date(), time_of_day) + datetime.timedelta(days=1) return dt + datetime.timedelta((day_of_week - dt.weekday()) % 7)

  • How much network overhead does TLS add compared to a non-encrypted connection?

    - by Daniel Sterling
    (Approximately) how many more bits of data must be transferred over the network during an encrypted connection compared to an unencrypted connection? IIUC, once the TLS handshake has completed, the number of bits transferred is equal to those transferred during an unencrypted connection. Is this accurate? As a follow up, is transferring a large file over https significantly slower than transferring that file over http, given fast processors and the same (ideal) network conditions?

  • Copy object into another

    - by EugeneP
    Is there an easy way how to achieve this: MyObj : (id, name); MyObj myObj_1 = new MyObj(1, "Name 1"); MyObj myObj_2 = new MyObj(2, "Name 2"); instead of myObj_2.setName(myObj_1.getName()) etc do something as following: myObj_2.copyFrom(myObj_1) so that they are different instances, but have equal properties.

  • Grails + Spring Security one field login

    - by Miguel
    Hi all Is it possible, using spring security plugin 0.5.3 with Grails 1.2.1, to authenticate a user using only one field? I mean, for example, making j_username and j_password fields in the authentication form equal previous to the authentication. I read it was possible to define j_username field in Config.groovy with acegi plugin, in older versions of the plugin. Now it uses SecurityConfig.groovy but the possibility of defining the field exists no more. Any ideas?? Thanks a lot, Miguel

  • Can I use a single DateTime field on the Entity Framework model side when the value is stored in a set of Int fields in the actual database?

    - by Ivan
    The actual table in the database has separate integer fields for storing year, month, day, hour and minute values (all in UTC) (seconds and milliseconds are irrelevant for my task and considered equal to zero). Needless to say it would be of great convenience to have just one field of DateTime type on the application side and hide all the conversion under the cover of the Entity Framework model code. Any directions on how to do that? I am not very experienced with Entity Framework yet.

  • strcasecmp in C returns 156 instead of 0, any ideas why?

    - by hora
    I have the following code: printf("num: %d\n", strcasecmp(buf, "h\n")); And I get the following results when I try plugging in different letters: a: -7 g: -1 i: 1 j: 2 h: 156 H: 156 Should strcasecmp not return 0 when buf is equal to H or h? Any ideas why it's returning 156? I need to figure out how to check whether the user types H or h. Thanks!

  • WinForms/Console application on Mono, how to know it runs as root

    - by Lex Li-MSFT
    As we can execute such executables in two ways, such as "sudo mono test.exe", and "mono test.exe". Now I want to know how to detect whether this application is running as root inside the application itself. I tried to check user name like below and see whether they equal to "root", Thread.CurrentPrincipal.Identity.Name Process.GetCurrentProcess().StartInfo.UserName AppDomain.CurrentDomain.ApplicationIdentity.FullName The first two are empty strings always, while the third throws NullReferenceException. Please advise if this is doable on Mono 2.6.

  • How do I dynamically reference incremented properties in C#?

    - by Jeff Blankenburg
    I have properties called reel1, reel2, reel3, and reel4. How can I dynamically reference these properties by just passing an integer (1-4) to my method? Specifically, I am looking for how to get an object reference without knowing the name of the object. In Javascript, I would do: temp = eval("reel" + tempInt); and temp would be equal to reel1, the object. Can't seem to figure this simple concept out in C#.

    What is the right way to build iPhone core data for this SMS like app (with location)? - I want to represent an entity of conversation with "profile1" "profile2" that heritage from a profile entity, and a message entity with: "to" "from" "body" where the "to" and "from" are equal to "profile1" and/or "profile2" in the conversation entity. How can I make such a relationships? is there a better way to represent the data (other structure)? Thanks

  • How to render an object tree with paging?

    - by erikzeta
    I’ll render an object graph on a page looking like this: Category 1 Module 1 Product 1 Product 2 Product 3 Module 2 Product 4 Category 2 ... The Category has an IList<Module and the Module contains an IList<Product Now I need to implement paging on this structure but the problem is that I can’t do Category.Skip(page * pageSize).Take(pageSize) because this will only work on the Category object not the whole object tree. In other words I like to render out when the sum of Categories, Modules and Products is equal to the PageSize /erik

  • Algorithm for finding symmetries of a tree

    - by Paxinum
    I have n sectors, enumerated 0 to n-1 counterclockwise. The boundaries between these sectors are infinite branches (n of them). The sectors live in the complex plane, and for n even, sector 0 and n/2 are bisected by the real axis, and the sectors are evenly spaced. These branches meet at certain points, called junctions. Each junction is adjacent to a subset of the sectors (at least 3 of them). Specifying the junctions, (in pre-fix order, lets say, starting from junction adjacent to sector 0 and 1), and the distance between the junctions, uniquely describes the tree. Now, given such a representation, how can I see if it is symmetric wrt the real axis? For example, n=6, the tree (0,1,5)(1,2,4,5)(2,3,4) have three junctions on the real line, so it is symmetric wrt the real axis. If the distances between (015) and (1245) is equal to distance from (1245) to (234), this is also symmetric wrt the imaginary axis. The tree (0,1,5)(1,2,5)(2,4,5)(2,3,4) have 4 junctions, and this is never symmetric wrt either imaginary or real axis, but it has 180 degrees rotation symmetry if the distance between the first two and the last two junctions in the representation are equal. Edit: This is actually for my research. I have posted the question at mathoverflow as well, but my days in competition programming tells me that this is more like an IOI task. Code in mathematica would be excellent, but java, python, or any other language readable by a human suffices. Here are some examples (pretend the double edges are single and we have a tree) http://www2.math.su.se/~per/files.php?file=contr_ex_1.pdf http://www2.math.su.se/~per/files.php?file=contr_ex_2.pdf http://www2.math.su.se/~per/files.php?file=contr_ex_5.pdf Example 1 is described as (0,1,4)(1,2,4)(2,3,4)(0,4,5) with distances (2,1,3). Example 2 is described as (0,1,4)(1,2,4)(2,3,4)(0,4,5) with distances (2,1,1). Example 5 is described as (0,1,4,5)(1,2,3,4) with distances (2). So, given the description/representation, I want to find some algorithm to decide if it is symmetric wrt real, imaginary, and rotation 180 degrees. The last example have 180 degree symmetry. (These symmetries corresponds to special kinds of potential in the Schroedinger equation, which has nice properties in quantum mechanics.)
