  • Service Discovery in J2ME

    - by thiagolee
    Hello, I have an application to run on a cell phone equipped with Wi-Fi and an application on a desktop which I want to communicate with. The problem is that I want to find in a Local Area Network the IP and port of the machine who has my service running. I can guarantee that there will be at maximum only one machine running it. I searched a lot for a way to do this but I ended up with nothing. I read something about WebServices, but it didn't seen to be what I wanted, what I want is really simple. I actually found a solution for it, but it can't be ported to J2ME. Anyone can help? Thanks.

  • Best Practice for loading non-existent data

    - by Aizotu
    I'm trying to build a table in MS SQL 2008, loaded with roughly 50,000 rows of data. Right now I'm doing something like: Create Table MyCustomData ( ColumnKey Int Null, Column1 NVarChar(100) Null, Column2 NVarChar(100) Null Primary Key Clustered ( ColumnKey ASC ) WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON ) ) CREATE INDEX IDX_COLUMN1 ON MyCustomData([COLUMN1]) CREATE INDEX IDX_COLUMN2 ON MyCustomData([COLUMN2]) DECLARE @MyCount Int SET @MyCount = 0 WHILE @MyCount < 50000 BEGIN INSERT INTO MyCustomData (ColumnKey, Column1, Column2) Select @MyCount + 1, 'Custom Data 1', 'Custom Data 2' Set @MyCount = @MyCount + 1 END My problem is that this is crazy slow. I thought at one point I could create a Select Statement to build my custom data and use that as the datasource for my Insert Into statement. i.e. something like INSERT INTO MyCustomData (ColumnKey, Column1, Column2) From (Select Top 50000 Row_Count(), 'Custom Data 1', 'Custom Data 2') I know this doesn't work, but its the only thing I can show that seems to provide an example of what I'm after. Any suggestions would be greatly appriciated.

  • How to edit files on the users file system from my web server?

    - by Abs
    Hello all, I am really looking for implementation advice as I have entered a new realm that I am not familiar with. At the simplest level, I would like to find a way that I can read/write to a users machine from my web server. For this to work, I think I will have to install some sort of "plugin" on the users machine which can receive (or poll?) the server for instructions. The above is the line of thought that I currently have, maybe using JAVA to do this. This needs to work on Linux, Mac and Windows OS. I am really looking for advice on the above, is it a good idea? Is there a better way of doing this? Is there something out there already that I can build on top of? I really appreciate all input and advice as this is something I have not done before. Thanks all

  • How do I specify both icons for a universal iPhone/iPad app?

    - by byamabe
    I hope to create a single app that supports both the iPhone and the iPad. The app works in the simulator for both devices as desired. Now I'm trying to build and deploy it. I set the "Icon File" in the plist to the 57x57 .png image and when I build and try to submit the app ItunesConnect complains about needing a 72x72 .png image for the iPad. If I specify the "Icon File" to the 72x72 .png ItunesConnect complains about needing a 57x57 image for the iPhone. How do I specify both icons in a single plist?

  • SO style alert header

    - by Zachary
    I apologize if this question is vague, but I want to build a drop down header, very similar to the one on StackOverflow that alerts you whenever you have earned a new badge, or on Twitter whenever a new tweet comes in. I've been looking around on the internet for a tutorial, but I'm having trouble googling exactly what I'm looking for. I assume there is a way to do this in jQuery, or there may be a jQuery plugin for it, but I haven't had any luck finding one. The idea would probably be to make an AJAX request every so many seconds, and if a new alert-worthy item is found, display it for the user. If someone could point me to a resource to learn how to build one, and/or an existing plugin, that would be great.

  • PHP Framework Benefits / Downfalls

    - by Lizard
    I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can definitely see the benefits of MVC keeping the logic separate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

  • memcpy does not copy the data

    - by user437777
    I am caught up with a weird problem. I have one build that copies data using memcpy, while another build does not. I don't understand why, because the relevant file is still the same. I am using following code: memcpy(pxCurrentInfo, &pxInfoBuffer->axgInfoBuffer[0], sizeof(tInfo)); Data in pxInfoBuffer is fine. When I check pxCurrentInfo they are all 0s. tInfo is a structure. To give a pointer, when I put the break point and change the value pxCurrentInfo->xDL.eMethod=0 it automatically updates/copies all the correct info from pxInfoBuffer->axgInfoBuffer[0], afterwards. I don't know why.

  • Android on Desktop tutorials/resources

    - by Ascension Systems
    I'm aware of the android-x86 project and as far as the end result (bootable live/install iso), I am looking to do the same thing. The difference is, I'm looking to do this with the ice cream sandwich branch from android master repo. Ice cream sandwich adds full support for x86 hardware and even sports a build target specifically for running the OS in virtualbox. So my question is, is anyone aware of any documentation for building and deploying to that target? Just in case it's not clear, I'm not just using the android-x86 project because they haven't yet put up a build for anything later than android 3.

  • Best neural network for certain type of pattern analysis?

    - by fred basset
    Hi All, I'm working on a system that will send telemetry data on machine operation back to a central server for analysis. One of the machine parameters we're measuring is motor current drawn vs time. After an operation is finished we plan to send back an array of currents vs time to the server. A successful operation would have a pattern like a trapezoid, problematic operations would have a pattern completely different, more like a large spike in values. Can anyone recommend a type of neural network that would be good at classifying these 1D vectors of current values into a pass/fail type output? Thanks, Fred

  • Counting builds

    - by moz
    I have a dozen of build plans managed by a unique build agent. What I want to do, is to get the total number of triggered/scheduled builds (without counting them manually from the interface). So, question is, is there a kind of counter on the server? UPDATE #1: I'm using the v2.2.1. UPDATE #2: On the server interface (Administration - System - System Information), there are some statistics including how many builds the server performed. But, this number is reinitialized when the server goes down.

    - by Najeeb Thalakkatt
    I have a single node hadoop machine in which hbase is running in the amazone ec2 instance. Due to some reason the server got restarted. So i need to start hadoop and hbase again. Then its working fine, but the old data in the hbase cannot be accessed through the web-servies. While i use the shell command its working fine, i am getting the data. So i created the scenario on my local server machine, but its working fine. The version details are as follows. hadoop-0.20.2 hbase-0.90.5 apache-tomcat-7.0.30 in Amazon ec2 medium instance And i use restful web-services with Orm-hbase to access data.

  • Make network changes permanent - C++

    - by pparescasellas
    I need to allow an external client to change the IP of the Linux machine where the program is running (C++). I already know how to list all the local interfaces and the current IPs assigned to them. I also know how to programatically change said IPs. What I need to know is how to make this change permanent so, if the machine reboots, it keeps the same network configuration. What's the best way to do this? Manually parsing /etc/network/interfaces? Calling some linux command? Edit: I'm using Debian. Thanks!

  • How much does precomputation (matching a series of strings and their permutations with a set number

    - by nipun
    Consider a typical slots machine with n reels(say reel1: a,b,c,d,w1,d,b, ..etc). On play we generate a concatenated string of n objects (like for above, chars) We have a paytable which lists winning strings with payout amounts. The problem is a wild character (list of wilds: w1,w2) which can replace {w1:a,b,c},{w2:a} ..etc. Is it really worthwhile to have all possible winning strings permutations with the wilds precomputed and used or simply at the time of occurance, generate all combinations with the pattern in hand accordingly. I did'nt really see much difference initially, but now if I need to scale the machine to handle 11+ reels with a much higher concentration of wilds than previously, I need to figure out the exact approach for this particular bit. Any ideas will be really appreciated :)

  • monitor and kill runaway processes using 100% IO?

    - by bleomycin
    Hello everyone, i have a few processes that have to be run at high priority (chrt 98) that will occasionally decide to hard-lock and peg 1 core at 100% (not a huge deal) but more importantly it will use all the IO on a system, so much that its impossible to log into the machine via ssh to kill it or perform any task on the machine that isn't loaded into ram. If i happen to have something like htop already running i am able to end the process fine. Is there any type of utility/way to monitor for this type of runaway process and kill anything that uses 100% of system IO for more than X amount of time? Thanks!

  • SQL Server 2008 R2 Enterprise won't install on Windows 2008 R2 Enterprise

    - by Carlos Paulino
    I've been trying to install SQL Server on a new Windows Server 2008. I have tried everything but I haven't been able to narrow down the problem. When the installation fails I get " Exit code (Decimal): -2068643839". The problem with this is that according to Microsoft this is a generic error code. I follow their guide to look into the detail.txt inside C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log\ But I can't find something that specifies the exact error. Any suggestions ? Thanks in advanced. I uploaded to detail.txt to http://www.megaupload.com/?d=0MV46SZH because it is to big to paste here. Below is the summary.txt ---------- Overall summary: Final result: SQL Server installation failed.

  • Sign an OpenSSL .CSR with Microsoft Certificate Authority

    - by kce
    I'm in the process of building a Debian FreeRadius server that does 802.1x authentication for domain members. I would like to sign my radius server's SSL certificate (used for EAP-TLS) and leverage the domain's existing PKI. The radius server is joined to domain via Samba and has a machine account as displayed in Active Directory Users and Computers. The domain controller I'm trying to sign my radius server's key against does not have IIS installed so I can't use the preferred Certsrv webpage to generate the certificate. The MMC tools won't work as it can't access the certificate stores on the radius server because they don't exist. This leaves the certreq.exe utility. I'm generating my .CSR with the following command: openssl req -nodes -newkey rsa:1024 -keyout server.key -out server.csr The resulting .CSR: ******@mis-ke-lnx:~/G$ openssl req -text -noout -in mis-radius-lnx.csr Certificate Request: Data: Version: 0 (0x0) Subject: C=US, ST=Alaska, L=CITY, O=ORG, OU=DEPT, CN=ME/emailAddress=MYEMAIL Subject Public Key Info: Public Key Algorithm: rsaEncryption RSA Public Key: (1024 bit) Modulus (1024 bit): 00:a8:b3:0d:4b:3f:fa:a4:5f:78:0c:24:24:23:ac: cf:c5:28:af:af:a2:9b:07:23:67:4c:77:b5:e8:8a: 08:2e:c5:a3:37:e1:05:53:41:f3:4b:e1:56:44:d2: 27:c6:90:df:ae:3b:79:e4:20:c2:e4:d1:3e:22:df: 03:60:08:b7:f0:6b:39:4d:b4:5e:15:f7:1d:90:e8: 46:10:28:38:6a:62:c2:39:80:5a:92:73:37:85:37: d3:3e:57:55:b8:93:a3:43:ac:2b:de:0f:f8:ab:44: 13:8e:48:29:d7:8d:ce:e2:1d:2a:b7:2b:9d:88:ea: 79:64:3f:9a:7b:90:13:87:63 Exponent: 65537 (0x10001) Attributes: a0:00 Signature Algorithm: sha1WithRSAEncryption 35:57:3a:ec:82:fc:0a:8b:90:9a:11:6b:56:e7:a8:e4:91:df: 73:1a:59:d6:5f:90:07:83:46:aa:55:54:1c:f9:28:3e:a6:42: 48:0d:6b:da:58:e4:f5:7f:81:ee:e2:66:71:78:85:bd:7f:6d: 02:b6:9c:32:ad:fa:1f:53:0a:b4:38:25:65:c2:e4:37:00:16: 53:d2:da:f2:ad:cb:92:2b:58:15:f4:ea:02:1c:a3:1c:1f:59: 4b:0f:6c:53:70:ef:47:60:b6:87:c7:2c:39:85:d8:54:84:a1: b4:67:f0:d3:32:f4:8e:b3:76:04:a8:65:48:58:ad:3a:d2:c9: 3d:63 I'm trying to submit my certificate using the following certreq.exe command: certreq -submit -attrib "CertificateTemplate:Machine" server.csr I receive the following error upon doing so: RequestId: 601 Certificate not issued (Denied) Denied by Policy Module The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377) Certificate Request Processor: The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377) Denied by Policy Module My certificate authority has the following certificate templates available. If I try to submit by certreq.exe using "CertificiateTemplate:Computer" instead of "CertificateTemplate:Machine" I get an error reporting that "the requested certificate template is not supported by this CA." My google-foo has failed me so far on trying to understand this error... I feel like this should be a relatively simple task as X.509 is X.509 and OpenSSL generates the .CSRs in the required PKCS10 format. I can't be only one out there trying to sign a OpenSSL generated key on a Linux box with a Windows Certificate Authority, so how do I do this (perferably using the off-line certreq.exe tool)?
