  • No "Distribution" setting in latest XCode??

    - by Rob
    For some reason, a choice for "Distribution" configuration is not showing up for building an app in the latest XCode 3.2.2 with iPhone SDK 3.2 when I'm trying to build an app for the iPad Any one else seeing this? I can set it to "Debug" or "Release" but there isn't even an option for Distribution.

  • Is there any small linux distribution which comes with a complete C devleopment environment

    - by hits_lucky
    Hi, I have installed "Damn Small Linux" on my home computer for doing C development in unix. But the distribution doesn't by default come with the C development environment and I am facing some issues when trying to install the gcc. Is there any other small Linux distribution which by default has the required packages for the C development. And also I don't want additional software which takes up lot of space but still would like to have the graphical environment. Thanks

  • probability and relative frequency

    - by Alexandru
    If I use relative frequency to estimate the probability of an event, how good is my estimate based on the number of experiments? Is standard deviation a good measure? A paper/link/online book would be perfect. http://en.wikipedia.org/wiki/Frequentist

  • 2D Array values frequency

    - by Morano88
    If I have a 2D array that is arranged as follows : String X[][] = new String [][] {{"127.0.0.9", "60", "75000","UDP", "Good"}, {"127.0.0.8", "75", "75000","TCP", "Bad"}, {"127.0.0.9", "75", "70000","UDP", "Good"}, {"127.0.0.1", "", "70000","UDP", "Good"}, {"127.0.0.1", "75", "75000","TCP", "Bad"} }; I want to know the frequency of each value .. so I27.0.0.9 gets 2. How can I do a general solution for this ? In Java or any algorithm for any language ?

  • order keywords by frequency in PHP mySql

    - by Gusepo
    Hello, I've got a database with video ids and N keywords for each video. I made a table with 1 video ID and 1 keyword ID in each row. What's the easiest way to order keywords by frequency? I mean to extract the number of times a keyword is used and order them. Is it possible to do that with sql or do I need to use php arrays? Thanks

  • Which Linux distribution for vehicle LCD instrument panel

    - by Brent
    I will be designing an instrument panel for a vehicle to display the common gauges that you would find in a car - (speedometer, rpm, fuel level, oil pressure, etc.). We have selected a 7" LCD and are in the process of narrowing down the hardware (This will use an ARM processor). The idea is to read these values off of the CAN Bus and update the UI with those values. This needs to have a fairly quick boot time, 5-10 seconds would be acceptable from the time the ignigtion is turned on to the time the UI is running. I have been doing a lot of research on which linux distribution to use, but I wanted to ask the question here to get the community's suggestions. I have been a .NET programmer for years, so linux is a new world to me. Here is what I have found so far... Tizen is geared for In-Vehicle Infotainment (IVI) (plus some others). However, this project is not an IVI, and I do not need the phone dialer, navigation, etc. Meego is dead, and Tizen seems to be the replacement Angstrom, Debian... would either of these be useful? I am not tied to a particular programming language or IDE. Any help and direction is appreciated!

  • Internal Code Signing: Key Distribution, or Certificate Server?

    - by Myrddin Emrys
    I should first note that we have nobody in IT with significant familiarity with self-signed certification. We have a moderately sprawling network (one forest, many locations), and we are now rolling out internal code signing; until now users have run untrusted code, or we even disabled(!) the warnings. Intranet applications, scripts, and sites will now be signed with self certification. I am aware of two obvious ways we can deploy this: Distributing the keys directly via a group policy, and setting up a cert server. Can someone explain the trade-offs between these two methods? How many certs before the group policy method is unwieldy? Are they large enough that remote users will have issues? Does the group policy method distribute duplicates on every login? Is there a better method I am not aware of? I can find a lot of documentation on certifications and various ways to create them, but I have not been able to find something that summarizes the difference between the distribution methods and what criteria make one or the other superior.

  • Upgrade of Ubuntu 8.10 distribution fails due to missing packages

    - by Tim
    I have a server that I've forgotten to upgrade for ages, which is still running Intrepid (8.10). I'd like to upgrade it to a newer version of the distribution, so that I can get security patches etc. I found some instructions that tell me to install the package update-manager-core. I tried the following: $ sudo apt-get install update-manager-core but this fails since some of the necessary packages can't be found: ... Err http://archive.ubuntu.com intrepid/main python-apt 0.7.7.1ubuntu4 404 Not Found [IP: 91.189.88.40 80] Err http://archive.ubuntu.com intrepid-updates/main update-manager-core 1:0.93.34 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/p/python-apt/python-apt_0.7.7.1ubuntu4_amd64.deb 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/u/update-manager/update-manager-core_0.93.34_amd64.deb 404 Not Found [IP: 91.189.88.40 80] ... I know that Intrepid is no longer supported, and so I guess some of the necessary files may no longer be maintained. But this seems rather unhelpful: I can't upgrade because it's too old, and the only way to fix this would be to upgrade it. Is there a way round this? Is something else wrong?

  • Setting up multiple wireless access points on same network

    - by SqlRyan
    I'd like to add wireless to my network, and I need multiple access points to cover the whole area. I'd like to set them up so that there's only one "wireless network" that the clients see, and it switches them as seamlessly as possible between access points as they wander around (if that's not possible, then at least have it so that they don't need to set up the security by hand on each one the first time, if possible). I've searched online, and there are quite a few sets of mixed instructions (same vs different SSID, frequency, does the security need to match exactly, etc.). Can somebody who has some experience doing this please let me know what they did? I imagine it's pretty simple, but there seems to be no clear cut "yes, you can do this" online, even though I know you can. I have a mid-size LAN with about 20 workstations and two Domain Controllers on it. Also, I'll be doing this with consumer wireless components, if it makes a difference, not enterprise-level components (ie. Linksys rather than Cisco).

  • Update frequency for dynamic favicons

    - by rosscowar
    I wanted to learn how to dynamically update the favicon using the Google Chrome browser and I've noticed that the browser seems to throttle how often you can update the favicon per second and that sort of makes things look sloppy. The test page I've made for this is: http://staticadmin.com/countdown.html Which is simply a scrolling message displaying the results of a countdown. I added an input field to tweak how many pixels per second are moved by the script and I've eyeballed the max to be about 5 frames per second smoothly in Google Chrome and I have not tested it in any other browsers. My question is what is the maximum frequency, are there any ways to change, is there a particular reason behind it? NOTE: I've also noticed that this value changes based on window focus as well. It seems to drop to about 1 update per second when the browser's window isn't in focus and returns to "max" when you return.

  • How to simulate different CPU frequency and limit RAM

    - by user351103
    Hi I have to build a simulator with C#. This simulator should be able to run a second thread with configureable CPU speed and limited RAM size, e.g. 144MHz and 50 MB. Of course I know that a simulator can never be as accurate as the real hardware. But I try to get almost similar performance. At the moment I'm thinking about creating a thread which I will stop/sleep from time to time. Depending on the desired CPU speed the simulator should adjust the sleep time of this thread and therefore simulate different cpu frequency. To measure the achieved speed I though about using PerformanceCounters. But with this approach I have the problem that I don't know how to limit the RAM size the thread could use. Do you have any ideas how to realize such a simulator? Thanks in advance!!

  • Data on the Frequency of Edit Operations Required to Correct a Misspelt Word

    - by gvkv
    Does anybody know of any data that relates to the frequency of the types of mistakes the people make when they misspell a word? I'm not referring to words themselves, but tje errors that are made by the typist. For example, I personally make transposition errors the most followed by deletion errors (that is, not including a letter I should), substitution errors and lastly, insertion errors. However, it would not surprise me to find out that typing a wrong letter (a substitution error, e.g., xat instead of cat) is more frequent than not including a letter. My purpose is to be able to make best guesses at correcting a word when I only have the original user's input. The idea being that if one type of error is more frequent than others, then it's more likely that correcting a word via that type of operation is correct. I don't object to using a database of commonly misspelt words but I prefer an algorithmic solution to depending on a corpus--especially if it might be faster.

  • Tracking/Counting Word Frequency

    - by Joel Martinez
    I'd like to get some community consensus on a good design to be able to store and query word frequency counts. I'm building an application in which I have to parse text inputs and store how many times a word has appeared (over time). So given the following inputs: "To Kill a Mocking Bird" "Mocking a piano player" Would store the following values: Word Count ------------- To 1 Kill 1 A 2 Mocking 2 Bird 1 Piano 1 Player 1 And later be able to quickly query for the count value of a given arbitrary word. My current plan is to simply store the words and counts in a database, and rely on caching word count values ... But I suspect that I won't get enough cache hits to make this a viable solution long term. Can anyone suggest algorithms, or data structures, or any other idea that might make this a well-performing solution?

  • FFT in MATLAB: wrong 0Hz frequency

    - by roujhan
    Hello I want to use fft in MATLAB to analize some exprimental data saved as an excell file. my code: A=xlsread('Book.xls'); G=A'; x=G(2, : ); N=length(x); F=[-N/2:N/2-1]/N; X = abs(fft(x-mean(x),N)) X = fftshift(X); plot(F,X) But it plots a graph with a large 0Hz wrong component, my true frequency is about 395Hz and it is not shown in the plotted graph. Please tell me what is wrong. Any help would be appreciated.

  • indexing according to frequency

    - by Bfu38
    sorry to bother you. I have a data.frame like this: 24.8 23.2 22.8 22.5 22.5 22.4 22.4 22.4 22.3 22.2 22.2 22.2 22 21.9 21.9 21.8 I would like to add an index according to the frequency, to have the following output: 24.8 1 23.2 1 22.8 1 22.5 2 22.5 2 22.4 3 22.4 3 22.4 3 22.3 1 22.2 3 22.2 3 22.2 3 22 1 21.9 2 21.9 2 21.8 1 How this can be done? in other words, since 28.8 occurs 1 time, it will have the index 1; since 22.5 occurs two times, it will have index 2 and so on.

  • "Delivered-To" Header in Exchange

    - by Kaii
    In some SMTP server implementations (i.e. Postfix) you can enable Delivered-To and X-Original-To headers that will be added to your email. (or [X-]Envelope-To) This is very helpful with distribution lists to determine which e-mail address the mail has been redirected to. So, when the mail has been sent to [email protected], you can see in the Delivered-To or Envelope-To header that it has been redirected (distributed) to [email protected], which is one of many other e-mail addresses that are linked to a single mailbox. How do I find which address was used to deliver this mail to a specific mailbox on Microsoft Exchange 2010? Looking at the plain message (with all headers) i can not find any information that the mail arrived via address [email protected] I think I need the Delivered-To header (or a similar one) to be set on Microsoft Exchange when a mail is delivered via distribution lists. Is there any way to enable such header in Exchange 2010? I need it so that our Ticket system (OTRS) correctly recognizes where the ticket belongs to. Adding all the e-mail addresses of all distribution lists to the system configuration is not the right solution. And if there is a solution for Exchange 2010, is this possibly also applicable to Exchange 2007?

  • Using ddply() to Get Frequency of Certain IDs, by Appearance in Multiple Rows (in R)

    - by EconomiCurtis
    Goal If the following description is hard follow, please see the example "before" and "after" to see a straightforward example. I have bartering data, with unique trade ids, and two sides of the trade. Side1 and Side2 are baskets, lists of item ids that represent both sides of the barter transaction. I'd like to count the frequency each ITEM appears in TRADES. E.g, if item "001" appeared in 3 trades, I'd have a count of 3 (ignoring how many times the item appeared in each trade). Further, I'd like to do this with the plyr ddply function. (If you're interested as to my motivation, I working over many hundreds of thousands of transactions and am already using a ddply to calculate several other summary statistics. I'd like to add this to the ddply I'm already using, rather than calculate it after, and merge it into the ddply output.... sorry if that was difficult to follow.) In terms of pseudo code I'm working off of: merge each row of Side1 and Side2 by row, get unique() appearances of each item id apply table() function transpose and relabel output from table Example of the structure of my data, and the output I desire. Data Example (before): df <- data.frame(TradeID = c("01","02","03","04")) df$Side1 = list(c("001","001","002"), c("002","002","003"), c("001","004"), c("001","002","003","004")) df$Side2 = list(c("001"),c("007"),c("009"),c()) Desired Output (after): df.ItemRelFreq_byTradeID <- data.frame(ItemID = c("001","002","003","004","007","009"), RelFreq_byTrade = c(3,3,2,2,1,1)) One method to do this without ddply I've worked out one way to do this below. My problem is that I can't quite seem to get ddply to do this for me. temp <- table(unlist(sapply(mapply(c,df$Side1,df$Side2), unique))) df.ItemRelFreq_byTradeID <- data.frame(ItemID = names(temp), RelFreq_byTrade = temp[]) Thanks for any help you can offer!
