  • How to use Rx to asynchronously query Twitter search ?

    - by Jalfp
    Hi, I'm thinking about using Rx (Reactive Framework) in order to asynchronously query Twitter search API on a given keyword. The sample app I'd like to build should be able to display new tweets in the console. Do you think it is possible to do that ? Would it be simpler than using standard programming techniques ? How would you do that ? Thank ! Jeremy

  • cisco vpn client randomly disconnects with pfSense

    - by Andre
    My network has two gateways, one is a pfSense box that everyone uses. The other one is a TP-Link firewall essentially for tests. Some machines inside my network need to access a VPN through the Cisco VPN client. If one of those machines is using the pfSense box as the gateway, I experience random connection drops on the VPN. If I am using the TP-Link gateway that doesn't happen. I've tried changing the MTU in the pfSense box and that improved things a little bit but didn't really solve the problem. I also followed the guidelines for traffic shaping in pfSense and the connections still drop quite often. Ideas?

  • Mixing two wav music files of different size

    - by iphoneDev
    Hi, I want to mix audio files of different size into a one single .wav file. There is a sample through which we can mix files of same size [(http://www.modejong.com/iOS/#ex4 )(Example 4)]. I modified the code to get the mixed file as a .wav file. But I am not able to understand that how to modify this code for unequal sized files. If someone can help me out with some code snippet,i'll be really thankful.

  • How to open a program on particular desktop?

    - by Vi
    When I start GUI program, it's window appears appears on currently active desktop (essentially, on random desktop). How to make it to appear on the specified desktop? For example, at startup I want certain programs to be started and distributed to desktops. I've already set up config file of openbox to force some programs to always start on specific desktop. Ideally it should be like: start_on_desktop 1 gnome-terminal --tab -e program1 --tab -e program2 start_on_desktop 2 gnome-terminal --tab -e program3 --tab -e program4 start_on_desktop 3 firefox It should be able to start the same program on other desktop. Also dislike when I start program while being on desktop X then switch to desktop Y and SUDDENLY a program which should be on X appears on Y. When I start lots of programs on and switch often between desktops they end up being in chaos and I need to collect them together and redistribute sanely. Also I want the first initial gnome-terminal to be on desktop 3, but I also want subsequent gnome-terminals to be on the desktop where I pressed the keystroke (also configured in openbox) that launches gnome-terminal.

  • Problems with undo in VS2010, I need help figuring out what is wrong

    - by IZZO
    I have been battling with my Microsoft Visual C# 2010 Express for a while now. When I undo things some times it works fine and other times it replaces lines of code I didn't touch with lines I deleted. It seems to pick targets at random and most of the time I can easily repair what it has done or just not save the changes. This problem is starting to drive me crazy. Does anyone have any idea why this is happening to me? When I was using Microsoft Visual 2012 this never happen. I have tried to search this problem with no luck so far.

  • What is the Optimal Server Configuration for Split-Path Testing?

    - by doug
    I am far from an expert on Apache or any server for that matter, so i apologize if this question is poorly worded, which it likely is. We have always relied on a vendor for split-path testing (aka "AB Testing"). If you're not familiar with that term, it's a form of marketing research in which you slightly modify one of your web pages (usually one nearest the point of conversion), say for instance, by changing the position of the "Buy Now" button or its color/contrast/texture, then serving one of those two pages to a given user based on random selection. By doing split-path testing ourselves, I suspect we can do it far more cheaply and increase cycle times as well. What is the optimal set-up for these tests? "Optimal" is based on the following criteria: how quickly/easily new tests can be set-up and put online; and minimal disruption to overall site performance

    Hi, I have here a view with an image and the text view (with finite frame size) . I've already implemented the textview keyboard notification but the problem is that when inputting in the textview it still behind the keyboard (the text is not visible). It seems this problem occur when I have an Image view as background. Pls advise me how to fix this. Here's my sample code: http://snipplr.com/view/35758/textview-input-is-behind-the-keyboard/ Thanks

I have sample XMLs, they have been filled with those unnecessary information, I just need to change 1 parameter and send it. How can I use that already generated XML? Thanks,

  • Snow Leopard, PHP, and MySQL

    - by Peter
    I have just installed Snow Leopard and now my PHP/MySQL program ends in a "Segmentation fault". I have been searching the web for a solution, I realize that there are some issues with SL/PHP/MySQL, but I have not found anything that works yet. I downloaded the binary MySQL package mysql-5.1.42-osx10.6-x86_64. I have updated the php.ini file as suggested at various posts. When I run PHP and connect to the MySQL server the behavior is a bit random. In many cases it works fine to connect and read data. In my specific case the PHP program constructs a LOAD DATA LOCAL INFILE ... statement to load data from a text file. It should do several such queries after each other in a loop. It works one time but the halts in a "Segmentation fault". The program worked fine in Leopard, but not now. My versions are: OS 10.6.2, PHP 5.3.0, MySQL 5.1.42

  • plane bombing problems- help

    - by peiska
    I'm training code problems, and on this one I am having problems to solve it, can you give me some tips how to solve it please. The problem is something like this: Your task is to find the sequence of points on the map that the bomber is expected to travel such that it hits all vital links. A link from A to B is vital when its absence isolates completely A from B. In other words, the only way to go from A to B (or vice versa) is via that link. Notice that if we destroy for example link (d,e), it becomes impossible to go from d to e,m,l or n in any way. A vital link can be hit at any point that lies in its segment (e.g. a hit close to d is as valid as a hit close to e). Of course, only one hit is enough to neutralize a vital link. Moreover, each bomb affects an exact circle of radius R, i.e., every segment that intersects that circle is considered hit. Due to enemy counter-attack, the plane may have to retreat at any moment, so the plane should follow, at each moment, to the closest vital link possible, even if in the end the total distance grows larger. Given all coordinates (the initial position of the plane and the nodes in the map) and the range R, you have to determine the sequence of positions in which the plane has to drop bombs. This sequence should start (takeoff) and finish (landing) at the initial position. Except for the start and finish, all the other positions have to fall exactly in a segment of the map (i.e. it should correspond to a point in a non-hit vital link segment). The coordinate system used will be UTM (Universal Transverse Mercator) northing and easting, which basically corresponds to a Euclidian perspective of the world (X=Easting; Y=Northing). Input Each input file will start with three floating point numbers indicating the X0 and Y0 coordinates of the airport and the range R. The second line contains an integer, N, indicating the number of nodes in the road network graph. Then, the next N (<10000) lines will each contain a pair of floating point numbers indicating the Xi and Yi coordinates (1 No two links will ever cross with each other. Output The program will print the sequence of coordinates (pairs of floating point numbers with exactly one decimal place), each one at a line, in the order that the plane should visit (starting and ending in the airport). Sample input 1 102.3 553.9 0.2 14 342.2 832.5 596.2 638.5 479.7 991.3 720.4 874.8 744.3 1284.1 1294.6 924.2 1467.5 659.6 1802.6 659.6 1686.2 860.7 1548.6 1111.2 1834.4 1054.8 564.4 1442.8 850.1 1460.5 1294.6 1485.1 17 1 2 1 3 2 4 3 4 4 5 4 6 6 7 7 8 8 9 8 10 9 10 10 11 6 11 5 12 5 13 12 13 13 14 Sample output 1 102.3 553.9 720.4 874.8 850.1 1460.5 102.3 553.9

  • ssh into my mac from my ipod

    - by mechko
    Ok so this is what I got, but it don't look right... The set up is as follows: My Mac is on a wireless network, presumably behind a firewall over which I have no admin privileges. Further, said wireless network changes my internal IP randomly at random times, so I do not know what my ip is. Note that localhost is a variable ip I forward some port or the other to my dns: ssh -R 19999:localhost:22 sourceuser@remotehost connect to my remotehost from my machine: ssh sourceuser@remotehost and then connect to the port I forwarded: ssh localhost -p 19999 [solved] Second question, there are a bunch of ssh clients for the iphone. Which one should I use? EDIT: Since jailbreak is not illegal, simply frowned upon by the Corporation, I've decided to go with that. I have a nice shell with openssh and the works. Best of all, it's free and it does exactly what you expect.

  • In Opera 11, how can I set up shortcuts to switch to specific tabs?

    - by gphilip
    In Firefox on Linux, we can use Alt+1, Alt+2, etc. to switch to the first, second, etc. tabs, till the 9th tab. This is very useful to switch between tabs. In Opera 11 on Linux, I couldn't find a way to do this: the only way to switch among tabs seems to be to use Ctrl+Tab and then cycle till we reach the tab that we want. Needless to say, this "linear access" method is slower (and more annoying) than the random access available in FF. So my question is: How can I set up shortcuts in Opera 11 on Linux so that I can switch to one of the first nine tabs using a numbered shortcut?

  • Multiple .bkf files created in Backupexec 12.5 or 2010 related to heavy I/O?

    - by syuusuke
    Hey everyone, I was wondering if anyone who has used backupexec 12.5 or 2010 have ever experienced multiple .bkf files created for a single job. To describe what I mean by multiple files, the .bkf are being created with random file sizes under 2GB even though I've assigned the setting to chop the file after 10GB size. Some jobs will create 20x .bkf files in 1 job with file chunks ranging from 50MB to 800MB sizes. Is this is a sign of heavy I/O issues? Bandwidth limitations? I'm not sure, I'm here to seek some advices and suggestions. I've setup another backup server with the same exact settings and they seem to create a new .bkf file when 10GB limit has been reached. Although I am backing up different machines but I know my settings are an exact match to the problematic or atleast I think it's a problem.

  • spurious hardware memory 'errors' on hp dl380 g5's being generated

    - by friedchicken
    Hi All, i've got 2 new HP dl380g5 servers running HP's esxi4 patched to 219382. they have both been patched up to the latest hp firmware levels (firmware cd 8.7) both are running 32gb (4 x 8gb sticks) both servers are showing the same symptoms - the memory lights come on for two (random) dimms on the front of the server and the health led turns red. sometimes the server stays up and running with no problems. othertimes the server locks dead and only a power reset can bring it back. there is nothing showing in the ilo logs and nothing within the vmware hardware monitoring. the memory has been replaced i've got other customers that have been running dl380g5's with out any issues on esx3.5 - this is our first vsphere deployment with them. these are meant to go live soon so any advice would be great. thanks in advance.

  • File corruption

    - by firesoul
    Recently, almost every file I try to copy into my HDDs gets corrupted. When writing to the disk, some portion of the file is replaced by random bytes (Checked using Diff apps) There's no problem reading existing files. I'm pretty sure it's not the HDD, becasue I've tried another HDD (a brand new 1TB WD) and the problem still remains. I have an AMD Athlon 64 X2 CPU, an ASUS M2NE motherboard, 2 WD SATA II HDDs (320GB + 1TB) and 3GB of Corsair RAM. My OS is Windows 7 (64 bit) Now, what could be the cause of this? If it's the motherboard, can it be fixed by using a PCI SATA card?

    Possible Duplicate: How to mute the sound output on Windows Start up? I carry a laptop around. Sometimes I'll open it up in meetings or other quiet settings. The speaker is interrupted by the windows startup noise or Pandora refreshing it's page and starting to play a song or some other random computer noise. Is there a simple way to mute the sound on startup/resume/whatever? Kind of like the BIOS option to turn on or off the Num Lock.
