  • Must I loop to search results for a specific value?

    - by tag
    I have a table in the database: name Opinion Tim Tim has an opinion John other random text Dan Dan's random text Al Al says something else I call this data and get it back in getRecords.lastResult To access John's opinion, I could use: getRecords.lastResult[1].opinion But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion. My guess is I need some sort of a loop? Is there an easier way to search for John directly without a loop?

  • Ubuntu 10.04 Cant Adjust brightness on my lenevo Thinkpad?

    - by Mo.
    I cant seem to be able to adjust the brightness on my think-pad laptop running Ubuntu 10.04. In the power management applet it shows that the power is set to 100%, but even if i try to lower it the actual screen brightness dosent change. Any ideas of how I can get around this? I tried changing the brightness from the terminal but its already set to Max brightness (however the actual screen brightness is no that bright at all). Thanks

  • keyboard shortcut to switch focus between separate X screens?

    - by ang mo
    I'm using XFCE on a dual monitor setup, with Xorg configured to separate X screens (neither twinview nor cinerama is working on GF470 with latest nvidia drivers). I'm not using xrandr. Suppose I have firefox running on one screen (:0.0) and thunderbird on the other (:0.1). When I want to switch focus from thunderbird to firefox, I need to move my mouse pointer to the firefox window and click (alt-tab switches between windows on a single screen only). Is there any keyboard shortcut for switching focus between screens?

  • Installing CUDA on Ubuntu 12.04 with nvidia driver 295.59

    - by johnmcd
    I have been trying to get cuda to run on a nvidia gt 650m based laptop. I am running Ubuntu 12.04 with the nvidia 295.59 driver. Also, my laptop uses Optimus so I have install the driver via bumblebee. Bumblebee is not working correctly yet -- however I believe it is possible to install CUDA independently. To install CUDA I have followed the instructions detailed here: How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? However I am still running into problem building the sdk. I made the changes specified at the above link in common.mk, but I got the following (snippet) from the build process: make[2]: Entering directory `/home/john/NVIDIA_GPU_Computing_SDK/C/src/fluidsGL' /usr/bin/ld: warning: libnvidia-tls.so.302.17, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libnvidia-glcore.so.302.17, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link) /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv018tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv012glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv017glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv012tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv015tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv019tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv000glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv017tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv013tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv013glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv018glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv022tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv007tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv009tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv020tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv014glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv015glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv016tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv001glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv006tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv021tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv011tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv020glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv019glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv002glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv021glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv014tls' collect2: ld returned 1 exit status make[2]: *** [../../bin/linux/release/fluidsGL] Error 1 make[2]: Leaving directory `/home/john/NVIDIA_GPU_Computing_SDK/C/src/fluidsGL' make[1]: *** [src/fluidsGL/Makefile.ph_build] Error 2 make[1]: Leaving directory `/home/john/NVIDIA_GPU_Computing_SDK/C' make: *** [all] Error 2 The libraries that ld warns about are on my system and are installed on the system: $ locate libnvidia-tls.so.302.17 libnvidia-glcore.so.302.17 /usr/lib/nvidia-current/libnvidia-glcore.so.302.17 /usr/lib/nvidia-current/libnvidia-tls.so.302.17 /usr/lib/nvidia-current/tls/libnvidia-tls.so.302.17 /usr/lib32/nvidia-current/libnvidia-glcore.so.302.17 /usr/lib32/nvidia-current/libnvidia-tls.so.302.17 /usr/lib32/nvidia-current/tls/libnvidia-tls.so.302.17 however /usr/lib/nvidia-current and /usr/lib32/nvidia-current are not being picked up by ldconfig.

  • Checking data of all same class elements

    - by Tiffani
    I need the code to check the data-name value of all instances of .account-select. Right now it just checks the first .account-select element and not any subsequent ones. The function right now is on click of an element such as John Smith, it checks the data-name of the .account-select lis. If the data-names are the same, it does not create a new li with the John Smith data. If no data-names are equal to John Smith, then it adds an li with John Smith. This is the JS-Fiddle I made for it so you can see what I am referring to: http://jsfiddle.net/rsxavior/vDCNy/22/ Any help would be greatly appreciated. This is the Jquery Code I am using right now. $('.account').click(function () { var acc = $(this).data("name"); var sel = $('.account-select').data("name"); if (acc === sel) { } else { $('.account-hidden-li').append('<li class="account-select" data-name="'+ $(this).data("name") +'">' + $(this).data("name") + '<a class="close bcn-close" data-dismiss="alert" href="#">&times;</a></li>'); } }); And the HTML: <ul> <li><a class="account" data-name="All" href="#">All</a></li> <li><a class="account" data-name="John Smith" href="#">John Smith</a></li> </ul> <ul class="account-hidden-li"> <ul>

  • Pattern/Matcher in Java?

    - by user1007059
    I have a certain text in Java, and I want to use pattern and matcher to extract something from it. This is my program: public String getItemsByType(String text, String start, String end) { String patternHolder; StringBuffer itemLines = new StringBuffer(); patternHolder = start + ".*" + end; Pattern pattern = Pattern.compile(patternHolder); Matcher matcher = pattern.matcher(text); while (matcher.find()) { itemLines.append(text.substring(matcher.start(), matcher.end()) + "\n"); } return itemLines.toString(); } This code works fully WHEN the searched text is on the same line, for instance: String text = "My name is John and I am 18 years Old"; getItemsByType(text, "My", "John"); immediately grabs the text "My name is John" out of the text. However, when my text looks like this: String text = "My name\nis John\nand I'm\n18 years\nold"; getItemsByType(text, "My", "John"); It doesn't grab anything, since "My" and "John" are on different lines. How do I solve this?

  • Parsing back to 'messy' API strcuture

    - by Eric Fail
    I'm fetching data from an online database (REDcap) via API and the data gets delivered in as comma separated string like this, RAW.API <- structure("id,event_arm,name,dob,pushed_text,pushed_calc,complete\n\"01\",\"event_1_arm_1\",\"John\",\"1979-05-01\",\"\",\"\",2\n\"01\",\"event_2_arm_1\",\"John\",\"2012-09-02\",\"abc\",\"123\",1\n\"01\",\"event_3_arm_1\",\"John\",\"2012-09-10\",\"\",\"\",2\n\"02\",\"event_1_arm_1\",\"Mary\",\"1951-09-10\",\"def\",\"456\",2\n\"02\",\"event_2_arm_1\",\"Mary\",\"1978-09-12\",\"\",\"\",2\n", "`Content-Type`" = structure(c("text/html", "utf-8"), .Names = c("", "charset"))) I have this script that nicely parses it into a data frame, (df <- read.table(file = textConnection(RAW.API), header = TRUE, sep = ",", na.strings = "", stringsAsFactors = FALSE)) id event_arm name dob pushed_text pushed_calc complete 1 1 event_1_arm_1 John 1979-05-01 <NA> NA 2 2 1 event_2_arm_1 John 2012-09-02 abc 123 1 3 1 event_3_arm_1 John 2012-09-10 <NA> NA 2 4 2 event_1_arm_1 Mary 1951-09-10 def 456 2 5 2 event_2_arm_1 Mary 1978-09-12 <NA> NA 2 I then do some calculations and write them to pushed_text and pushed_calc whereafter I need to format the data back to the messy comma separated structure it came in. I imagine something like this, API.back <- `some magic command`(df, ...) identical(RAW.API, API.back) [1] TRUE Some command that can format my data from the data frame I made, df, back to the structure that the raw API-object came in, RAW.API. Any help would be very appreciated.

  • DNS updating issue

    - by Will
    Hey guys, I'm new to serverfault so please excuse me if I sound a tad nub. I work in an environment that is kinda peace mealed together, and I honestly don't know how it works. I'm new to the IT field and am still in school. When I replace a PC I rename the old one to mo-o-pcname and give the new one the proper name of mo-pcname (mo is a location thing we use so it really doesn't apply to the problem.) The new PC will function on the network; it will have the ability to access network resources (printers, file shares, etc) and it will have the ability to get out to the internet. However I can no longer ping the machine. It would appear as if the DNS (A) record is not getting updated or something. Like I said I'm kinda new to the field and just trying to work through this problem. Thanks for your help.

  • How can you Add Value to your Mobile Apps?

    - by Carlos Chang
    Author: Craig Mikus, Sr. Director, Enterprise Mobile Solutions Seems like every customer is either building or planning to build mobile apps, especially customer facing apps. Why? Inevitably, all companies want to improve the customer experience through more quality interactions that drive customer satisfaction, customer loyalty, new revenue streams, and even improve the way they service their customers. What better way than mobile apps? Right? But how can customers add more value to these mobile apps to drive more business benefit? Look closely, the answer just might be right in front of you. Still need another clue? What’s the first 4 letters of mobile – mo-bi? Or pronounced differently, More BI. That’s right – add more business intelligence to your overall mobile strategy. In today’s customer centric world where customer interactions and personalization are critical, it’s important to leverage a BI strategy that complements and feeds into your mobile strategy. For example, I was recently talking to a customer that was implementing a data warehouse project focused customer analytics. Their goal was to understand who are their best customers and why, develop customer profiles, identify customer trends & patterns, identify cross sell opportunities, and much more. The company then wanted to feed this information to marketing for targeted campaigns and programs. As we continued to talk, I asked my contact if they had plans to feed this information into their customer facing mobile apps to personalize the apps, target their interactions, and hopefully drive customer loyalty and new revenue streams? Two minutes later, my contact was calling his mobile development teams. So my advice to everyone, as you establish your enterprise mobile strategy and goals, remember that “mo-BI” is a critical component to add value to your mobile apps! So make sure you have “mo BI” in your mobile strategy. As I come to think of it, did you ever notice that Big Data also starts with BI?

  • condition in recursion - best practise

    - by mo
    hi there! what's the best practise to break a loop? my ideas were: Child Find(Parent parent, object criteria) { Child child = null; foreach(Child wannabe in parent.Childs) { if (wannabe.Match(criteria)) { child = wannabe; break; } else { child = Find(wannabe, criteria); } } return child; } or Child Find(Parent parent, object criteria) { Child child = null; var conditionator = from c parent.Childs where child != null select c; foreach(Child wannabe in conditionator) { if (wannabe.Match(criteria)) { child = wannabe; } else { child = Find(wannabe, criteria); } } return child; } or Child Find(Parent parent, object criteria) { Child child = null; var enumerator = parent.Childs.GetEnumerator(); while(child != null && enumerator.MoveNext()) { if (enumerator.Current.Match(criteria)) { child = wannabe; } else { child = Find(wannabe, criteria); } } return child; } what do u think, any better ideas? i'm looking for the niciest solution :D mo

  • Rewriting from headers in Postfix

    - by inxilpro
    I want to configure Postfix to replace the 'From' header in all forwarded/aliased messages with a custom email address, and the 'Reply-To' header with the original sender's address. Is that something that can be done with a simple configuration change, or am I looking at a more complex problem? For example: Original Message: From: "John Smith" <[email protected]> To: "Jane Rice" <[email protected]> Would get translated to: From: "My Email Forwarding Service" <[email protected]> Reply-To: "John Smith" <[email protected]> To: "Jane Rice" <[email protected]> Ideally, I would also have it rewrite the message body (adding something about how the message was forwarded for them), but I know that's much more difficult. We have a number of email aliases, and everytime someone reports spam they received through their alias, our server gets flagged. I'm trying to minimize that damage as much as possible. Any help is greatly appreciated!

  • Multiple contacts with shared information

    - by Keith Thompson
    Background: I currently have several hundred contacts, synchronized between a Microsoft Exchange server and several mobile devices. I also save exported copies of the contacts in .vcf format. Is there a good way (application, file format, whatever) to maintain contacts with shared information? A very common scenario is that I have contacts for two or more people who live in the same house, for example: John Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-2222 Mobile: 555-555-3333 E-mail: John[email protected] Jane Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-4444 Mobile: 555-555-5555 E-mail: [email protected] As you can see, both contacts have the same home address and phone number, but distinct names and work and mobile phone numbers. (Other information might also be either shared or distinct.) The applications and file formats I'm familiar with don't seem to have a good way to deal with this. If I use a single "John & Jane Doe" contact for both, it's difficult to distinguish the distinct information (if I want to call Jane's mobile phone rather than John's). If I use a separate contact for each, I have to remember to update both of them (or all of them for N 2) when they move or change their home phone number. An ideal solution would let me create a record containing information for their household, and have each of their contact records contain a reference to the household record, so that when I view John's contact record I see both shared and distinct information. Is there anything out there that has good support this kind of thing? (I would think there would be, since it's a very common scenario.) (I suppose I could roll my own system that generates merged .vcf files from some extended format, but that wouldn't play well with synchronizing across multiple devices.)

  • Thunderbird: how to move mails into correct thread? (mailing lists)

    - by unor
    I'm subscribed to some mailing lists and every day people reply to a wrong mail (or they don't reply at all), so that their mail lands in the wrong (or a new) thread. I set the mail display in "View ? Sort by" to "Threaded". Example: mailing list "Foobar": [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic [Foobar] I'm John Doe Re: [Foobar] I'm John Doe Re: [Foobar] Welcome, John Re: [Foobar] random topic There are two discussions, one about "random topic", one about "John Doe". The subject line changes in the discussion about John Doe, which is fine (no problem here). But the last mail should be pigeonholed in the first thread. Instead it is at the top-level. Now, how can I move that last mail into the correct thread? I tried to drag&drop it at the mail I think it should be a reply to, but this doesn't work. I think theoretically it should be possible by fiddling with the mail headers after receiving the mail, but this doesn't seem to be a comfortable way.

  • How to add LDAP user to existing local group in RHEL?

    - by Highway of Life
    I'm attempting to add some of our LDAP users to a locally defined group on our RHEL server, however I get an error stating that the LDAP user is not found in /etc/passwd. What would be the best way to allow LDAP users to be added to local groups? My feeling is that this must be done manually. I could edit: /etc/group and add the LDAP group to the list. Would that be ideal? [server]# id apache uid=409(apache) gid=409(apache) groups=409(apache) context=user_u:system_r:unconfined_t:s0 [server]# id john.doe uid=11389(john.doe) gid=6097(ABC_Corporate_US) groups=6097(ABC_Corporate_US) context=user_u:system_r:unconfined_t:s0 [server]# /usr/sbin/usermod -a -G apache john.doe usermod: john.doe not found in /etc/passwd OS: RHEL (Red Hat Enterprise Linux Server release 5.3 (Tikanga)) Note: Updating the OS on this machine is not an option.

  • Archiving mails with postfix: how to filter mails?

    - by Tronic
    i wanto to implement the following scenario: we use a postfix mailserver. to archive all old and new mails, i want to setup a second postfix on our fileserver and create a single mailbox "archive". then every mail gets forwarded as bcc to this mailbox automatically. now, i want to create different folders in a maildir structure and let the server move each mail to the right subfolder of the mailbox based on its sender or receiver. e.g. when we get a mail to one of our employees named "John Doe" at john[email protected], the mail should be moved to "Inbox/John Doe Incoming". the same applies when john doe sends a mail, folder would be "Inbox/John Doe Outgoing". how can i implement this filter behaviour. i heard of Procmail and Maildrop. Which of the two would you prefer? Which is more easy to configure? Any out-of-box solutions here? thanks in advance!

  • Managing Linux Directory Permissions & SFTP

    - by Dizzle
    Good morning; I have a RHEL 5.7 web server configured to allow SSH/SFTP only by specific groups. I'd like for content managers to upload content to their respective directories and have that content inherit the user/group ownership of the directory regardless of upload method or application. For example: John is in group "web" for SSH/SFTP rights and "finance" for directory permissions, and uploads to directory "webstuff" via SFTP. Directory "webstuff" has permissions of "2760" (rwxrws---), and ownership of "apache:finance". If John uploads an update to an existing file in "webstuff", the ownership of the file stays at "apache:finance". If John uploads a new file to "webstuff", the ownership of the file is "john:finance". My desire is to have any file from John uploaded to "webstuff" to change to the directory's owner. I've tried with setuid and setgid both set, but the user-ownership didn't take. I've seen mentions on ServerFault of using ACL's, or a chrooted jail for SFTP but I have yet to configure and test them, and I don't know if they're a viable solution (they could be, I just don't know because I've never done either). Any thoughts and assistance would be greatly appreciated.

  • [Ubuntu]df Total size is not correct compared with the size of the disk

On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.
