  • best practice to obtain time zone for iPhone vs iPod Touch

    - by johnbdh
    I am creating an app that requires the users current time zone. If the device being used is an iPhone and the user has their Time Zone set to automatically change, I think I can be fairly confident that localTimeZone or systemTimezone will give me the correct time zone for the user's location. If on the other hand the device is an iPod Touch, the time zone returned by localTimeZone and systemTimeZone appears to always be whatever time zone is set in the Date & Time settings, regardless of the user's actual location. I tried using location services but, while the lat/long is being provided properly, the time zone offset in the timesStamp I am getting is always the same as whatever the user has set for their time zone setting. Any suggestions? John

  • How to always run a service in the background

    - by Thomas H
    Hi I am in the process of creating an app that is similar to the build-in SMS app. What I need: - a service that is always running in the background - every 5 min. the service checks the current location of the device and calls a web service - if certain criteria are meet, the service should generate a notification (just like the SMS app) - when the notification is clicked, the user is taken to the app (just like the SMS app) - when the app is installed the service should be started - when the device is rebooted, the service should be started What I have tried: - running a regular service which worked just fine until android kills the service - using the AlarmManager the make the 5 min. interval call to a service. But I was not able to make this work. Any help would be greatly appreciated... -Thomas

  • Abort a slow flush to disk after write?

    - by Therealstubot
    Is there a way to abort a python write operation in such a way that the OS doesn't feel it's necessary to flush the unwritten data to the disc? I'm writing data to a USB device, typically many megabytes. I'm using 4096 bytes as my block size on the write, but it appears that Linux caches up a bunch of data early on, and write it out to the USB device slowly. If at some point during the write, my user decides to cancel, I want the app to just stop writing immediately. I can see that there's a delay between when the data stops flowing from the application, and the USB activity light stops blinking. Several seconds, up to about 10 seconds typically. I find that the app is holding in the close() method, I'm assuming, waiting for the OS to finish writing the buffered data. I call flush() after every write, but that doesn't appear to have any impact on the delay. I've scoured the python docs for an answer but have found nothing.

  • XDocument holding onto Memory?

    - by Jon
    I have an appplication that does a XDocument.Load from a 20mb file and then gets passed to a form to view its contents: openFileDialog1.FileName = ""; if (openFileDialog1.ShowDialog() == DialogResult.OK) { AuditFile = XDocument.Load(openFileDialog1.FileName); fmAuditLogViewer AuditViewer = new fmAuditLogViewer(); AuditViewer.ReportDocument = AuditFile; AuditViewer.Init(); AuditViewer.ShowDialog(); AuditViewer.Dispose(); AuditFile.RemoveNodes(); AuditFile = null; } In Task Manager I can see the memory being used by my application shoot up when I open this file. When I have finished viewing this file in my application I call : myXDocument.RemoveNodes(); myXDocument = null; However the memory use in Task Manager is still pretty high against my app. Is the XDocument still being held in memory and can I decrease the memory usage by my app?

  • Packet Crafting on a Mac

    - by JayCrossler
    I think (based on searching the forums), that NetCat is the best option, but wanted to hear if others are preferable. Anyone have good success with a packet-crafting tool (specifically on Mac)? I've tried HPing, but had some issues. I'm looking into NetCat ('nc' on mac) now, but it's not working as I had thought. Basically, I captured some packets that a remote control sends over a wifi network to turn lights on and off (using X10 controllers), and am looking for a way to replay them by crafting a TCP packet from the command line. I used Wireshark to sniff the traffic, so I know the package is: DEVICE -sendplc-"C4 DIM 10" I'm trying: echo 'DEVICE -sendplc-"C4 DIM 10"' nc 192.168.2.196 6003 but there's no response from the receiving system. The exact bytestream is (if anyone wants to check that I got the right dataframe): 08004642f1b400260897ad6308004500004b08e240004006aaf5c0a802c1c0a802c4d8d7177399aab39 e57ff4753801880ae37ea00000101080a323353ce01b406424445564943457e73656e64706c637e2243 34204f4e220a Next step I'm going to check is to make sure the packet arrives exactly by sniffing and compare it to the original. [EDIT: Also at ServerFault now: Packet Crafting on a Mac, so this one becomes a duplicate across the two sites]

  • Compressing three individual jpeg pics containing temporal redundancy?

    - by michael
    I am interfacing and embedded device with a camera module that returns a single jpeg compressed frame each time I trigger it. I would like to take three successive shots (approx 1 frame per 1/4 second) and further compress the images into a single file. The assumption here is that there is a lot of temporal redundancy, therefore lots of room for more compression across the three frames (compared to sending three separate jpeg images). I will be implementing the solution on an embedded device in C without any libraries and no OS. The camera will be taking pics in an area with very little movement (no visitors or screens in the background, maybe a tree with swaying branches), so I think my assumption about redundancy is pretty solid. When the file is finally viewed on a pc/mac, I don't mind having to write something to extract the three frames (so it can be a nonstandard cluge) So I guess the actual question is: What is the best way to compress these three images together given the fact that they are already in JPEG format (it is a possibly to convert back to a raw image, but if i dont have too...)

  • Sharepoint Site Administration

    - by Shrewd Demon
    Hey, I've got a SharePoint website running on my machine (which it shows me inside the Application Pool in the Inet Manager). Now this website has a different user credentials specified under the Identity section (properties). Also when I view the w3wp.exe in the task manager it shows that the site is running as a different user. The problem is that if I change the username and password of the existing user with mine, the site stops working. How do I run it under my account credentials. Please help. Thanks

  • GKSession sendDataToAllPeers including sender?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. If the device doing the sending is also a GKSessionModePeer, I would expect it to "fire" its receiveData: message as well since I'm sending to all peers. Should I call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would be calling sendDataToAllPeers: and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendDataToAllPeers: list so that it responds exactly the same as all connected peers?

    I work in a large resort style rental community. Recently I was given a promotion, though my senior management has found it difficult to come up with a job title. I hold the position of concierge manager, spa manager and special events coordinator. So I would like to come up with a job title that would encompass the three areas. The suggested title was Hospitality Director. However it sounds like I would be working at a Hotel. Can someone please give me some ideas. Thank you in advance

  • CUDA threads output different value

    - by kar
    HAi, I wrote a cuda program , i have given the kernel function below. The device memory is allocated through CUDAMalloc(); the value of *md is 10; __global__ void add(int *md) { int x,oper=2; x=threadIdx.x; * md = *md*oper; if(x==1) { *md = *md*0; } if(x==2) { *md = *md*10; } if(x==3) { *md = *md+1; } if(x==4) { *md = *md-1; } } executed the above code add<<<1,5>>(*md) , add<<<1,4>>>(*md) for <<<1,5>>> the output is 19 for <<<1,4>>> the output is 21 1) I have doubt that cudaMalloc() will allocate in device main memory? 2) Why the last thread alone is executed always in the above program? Thank you

  • GetDiskFreeSpaceEx reports wrong number of free bytes

    - by rboorgapally
    __int64 i64FreeBytes unsigned __int64 lpFreeBytesAvailableToCaller, lpTotalNumberOfBytes, lpTotalNumberOfFreeBytes; // variables used to obtain // the free space on the drive GetDiskFreeSpaceEx (Manager.capDir, (PULARGE_INTEGER)&lpFreeBytesAvailableToCaller, (PULARGE_INTEGER)&lpTotalNumberOfBytes, (PULARGE_INTEGER)&lpTotalNumberOfFreeBytes); i64FreeBytes = lpTotalNumberOfFreeBytes; _tprintf(_T ("Number of bytes free on the drive:%I64u \n"), lpTotalNumberOfFreeBytes); I am working on a data management routine which is a Windows CE command line application. The above code shows how I get the number of free bytes on a particular drive which contains the folder Manager.capdir (it is the variable containing the full path name of the directory). My question is, the number of free bytes reported by the above code (the _tprintf statement) doesn't match with the number of free bytes of the drive (which i check by doing a right click on the drive). I wish to know if the reason for this difference?

  • Do you feel underappreciated or resent the geek/nerd stigma?

    - by dotnetdev
    At work we have a piece of A4 paper with the number of everyone in the office. The structure of this document is laid out in rectangles, by department. I work for the department that does all the technical stuff. That includes support—bear in mind that the support staff isn't educated in IT but just has experience in PC maintenance and providing support to a system we resell but don't have source code access to, project manager, team leader, a network administrator, a product manager, and me, a programmer. Anyway, on this paper, we are labelled as nerds and geeks. I did take a little offence to this, as much as it is light hearted (but annoying and old) humour. I have a vivid image that a geek is someone who doesn't go out but codes all day. I code all day at home and at work (when I have something to code...), but I keep balance by going out. I don't know why it is only people who work with computers that get such a stigma. No other profession really gets the same stigma—skilled, technical, or whatever. An account manager (and this is hardly a skilled job) says, "Perhaps [MY NAME HERE] could write some geeky code tomorrow to add this functionality to the website." It is funny how I get such an unfair stigma but I am so pivotal. In fact, if it wasn't for me, the company would have nothing to sell so the account managers would be redundant! I make systems, they get sold, and this is what pays the wages. It's funny how the account managers get a commission for how many systems they sell, or manage to make clients resubscribe to. Yet I built the thing in the first place! On top of that, my brother says all I do is type stuff on a keyboard all day. Surely if I did, I'd be typing at my normal typing speed of 100wpm+ as if I am writing a blog entry. Instead, I plan as I code along on the fly if commercial pressures and time prohibit proper planning. I never type as if I'm writing normal English. There is more to our jobs than just typing code. And my brother is a pipe fitter with no formal qualifications in his name. I could easily, and perhaps more justifiably, say he just manipulates a spanner or something. Does you feel underappreciated or that a geek/nerd stigma is undeserved or unfair?

  • arm-apple-darwin9-g++ Bus error problem

    I want to create a mobilesubstrate plugin for iPhone OS 3.2 or I tried to setup toolchain on the iPad device. I have installed the iphone-gcc_4.2-20090304-1-9_iphoneos-arm package and all the relevant packages from Cydia, but when it comes to compiling the simplest source file shows the following error: arm-apple-darwin9-g++ -I /var/toolchain/sys/ -c -dynamiclib ExampleHookLibrary.mm -o ExampleHookLibrary.o arm-apple-darwin9-g++: Internal error: Bus error (program cc1objplus) Please submit a full bug report.

  • How can I programmatically find the IP address/netmask/gateway configured for a specific network dev

    - by Oren S
    Hi I would like to write a piece of code which checks, for each network device (e.g. eth0, lo, master devices) some statistics and configuration data about that device. I could find the statistics data (and most of the configuration data) in /sys/class/net/..., however, I couldn't find any C/C++ API or any entry in procfs/sysfs listing the inet addr, netmask and gateway. Some alternatives I checked: parsing the output from ifconfig/route/some other utilities: I don't want to start a subprocess every time I need to do the inspection. parsing /etc/sysconfig/network-scripts/: will give me only the start-up configuration, and not the current state. Also, since this code is intended for a product in my workplace, where every external library is inspected thoroughly (meaning it will take me forever to add any external library) I prefer solutions which rely on Linux native API and not external libraries. Thanks!

  • What are the names of network interfaces on the Motorola CLIQ?

    - by RS
    The network interfaces on Android interfaces are listed as directories in the file system in /sys/class/net/. For most Android devices the network interface for gprs traffic is called rmnet0 and for Wi-Fi it's usually eth0 or tiwlan0. I suspect that the cell interface for the Motorola CLIQ is rmnet0, but I would like to have this confirmed + know the name of the Wi-Fi interface. Also it would be good to know the device id for this model. This is the value available as android.os.Build.DEVICE in the Java SDK. (E.g. T-Mobile G1 uses dream, Samsung Galaxy uses GT-I7500, and Motorolda Droid uses sholes.)

  • What should I grab as a development platform, an iPod or an iPad?

    - by mmr
    Hey all, I've recently gotten into the world of contract programming, and two of my clients have indicated that they'd like to do something 'trendy', like ipod touch/iphone/ipad development. I have a mac laptop (first gen macbook pro) that I'll have to upgrade to snow leopard to do the development for any of them, from what I've read. So that's already a bit of a commitment, given all the stuff I have on that laptop I'll have to make sure is recoverable from backup. My budget is limited, but I think I need to learn this skill. Which device should I get to learn this kind of development, an iPod touch or an iPad? I don't have the money for an iPhone. I think that the iPhone/iPad SDK has an emulator mode, but I like to have the device I'm going to roll out on available to make sure that everything works as I'd expect, ie, what's easily readable on a laptop screen is still readable on the touch, etc.

  • apache front end using mod_proxy_ajp to tomcat on different servers

    - by user302307
    Anyone knows the steps to run Apache on server A as front end and run mod_proxy_ajp to connect to tomcat instances on server B? I want to run apache on sever A to do name based vhost that connects to many tomcat servers. I can run mod_proxy_ajp, only if apache and tomcat are on the same server. What I've tried so far: In server A, running Apache 2.2: NameVirtualHost *:80 ServerName tc0.domo.lan ErrorLog "C:\Apache\Apache2.2\logs\tc0.ajp.error.log" CustomLog "C:\Apache\Apache2.2\logs\tc0.ajp.access.log" combined DocumentRoot C:/htdocs0 AddDefaultCharset Off Order deny,allow Allow from all ProxyPass / ajp://192.168.77.233:8009/ ProxyPassReverse / ajp://192.168.77.233:8009/ Options FollowSymLinks AllowOverride None Order deny,allow Allow from all Server B: 192.168.77.233, tomcat 6 connector: I can confirm if going to http://192.168.77.233:8080/manager/html, tomcat works.
