  • How can I update my business' Facebook page via my Ruby on Rails app?

    - by Eric S.
    I'm creating a new rails app for my business, and I just finished a new feature where I can put an announcement on the website (for specials, sales, etc.). I want this announcement to automatically be set to my business' Facebook page. How can I easily do this? Is the only way to create a Facebook application, and then if so, can a Facebook application have permissions to edit a business' page (I know apps can edit user profiles, but I don't know about business pages)? Thanks for any help!

  • How to work with images(png's) of size 2-4Mb.

    - by Sam
    I am working with images of size 2 to 4MB. I want to edit image of resolution 1200x1600. performing scaling, traslation and rotation operations. I want to another images on that and saving it to photo album. My app is crashing(giving memory warning) after i successfully edit one image and save to album. I have releasing some images when i get memory warning. But still it crashes as i am working with 2 images of size 3MB each and context of size 1200x1600 and getting a image from the context at the same time. Is there any way to compress images and work with it by performing scaling, traslation and rotation operations?

  • animate each child jquery

    - by Martavis P.
    It's amazing how simple this should be but I can't get it to work. I'm looking to animate a set of divs one at a time. I am using animate.css for those familiar with it. I thought I may have found the answer here but jsFiddle is not working at the moment. Anywho, the code is $('.elements').each(function(i) { $(this).addClass('animated slideInLeft').delay(500); }); The problem is that when I debug and step through each element, the animation is happening for each element but when I let it run, it appears to all do it at once. What is needed to actually show the animation one at a time? Thanks EDIT: jsFiddle is back up and that link provided below did not help. The answer did not include looping through elements, but looping the animation itself. EDIT 2 Here is a Fiddle to play with if you guys need one.

  • Fitting an Image to Screen on Rotation iPhone / iPad ?

    - by user356937
    I have been playing around with one of the iPhone examples from Apple' web site (ScrollViewSuite) . I am trying to tweak it a bit so that when I rotate the the iPad the image will fit into the screen in landscape mode vertical. I have been successful in getting the image to rotate, but the image is larger than the height of the landscape screen, so the bottom is below the screen. I would like to image to scale to the height of the landscape screen. I have been playing around with various autoSizingMask attributes without success. The imageView is called "zoomView" this is the actual image which loads into a scrollView called imageScrollView. I am trying to achieve the screen to rotate and look like this.... olsonvox.com/photos/correct.png However, this is what My screen is looking like. olsonvox.com/photos/incorrect.png I would really appreciate some advice or guidance.

  • How to start dovecot?

    - by chudapati09
    I'm building a web server to host multiple websites. I got everything working except the mail server. I'm using linode to host my vps and I've been following their tutorials. FYI, I'm using Ubuntu 11.10. Here is the link I've been following, http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid. I got up to the part where it tells me to restart dovecot, so I tried "service dovecot restart". But then I get this "restart: Unknown instance:". I'm logged in as root, so I'm not using sudo. Since that didn't work I tried "/etc/init.d/dovecot restart" and I get "dovecot start/running, process 4760". So I try "/etc/init.d/dovecot status" and I get "dovecot stop/waiting". So I tried "service dovecot start" and I get "dovecot start/running, process 4781". So I tried to get the status, so I tired "service dovecot status" and got "dovecot stop/waiting" Then I tired "/etc/init.d/dovecot start" and I get "dovecot start/running, process 4794". So I tired to get the status, so I tired "/etc/init.d/dovecot status" and got "dovecot stop/waiting" Just for kicks and giggles I tired to kill the process, I used the PID that I got when I did "service dovecot start", this was the command "kill -9 4444" and I get this "bash: kill: (4805) - No such process" Am I doing something wrong? --EDIT 1-- The following are logs that were found in /var/log/syslog that involved dovecot dovecot: master: Dovecot v2.0.13 starting up (core dumps disabled) dovecot: ssl-params: Generating SSL parameters dovecot: ssl-params: SSL parameters regeneration completed dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) kernel: init: dovecot main process (10276) terminated with status 89 kernel: init: dovecot main process (10289) terminated with status 89 kernel: init: dovecot main process (10452) terminated with status 89 kernel: init: dovecot main process (2275) terminated with status 89 kernel: init: dovecot main process (3028) terminated with status 89 kernel: init: dovecot main process (3216) terminated with status 89 kernel: init: dovecot main process (3230) terminated with status 89 kernel: init: dovecot main process (3254) terminated with status 89 kernel: init: dovecot main process (3813) terminated with status 89 kernel: init: dovecot main process (3845) terminated with status 89 kernel: init: dovecot main process (4664) terminated with status 89 kernel: init: dovecot main process (4760) terminated with status 89 kernel: init: dovecot main process (4781) terminated with status 89 kernel: init: dovecot main process (4794) terminated with status 89 kernel: init: dovecot main process (4805) terminated with status 89 --Edit 2 (/etc/dovecot/dovecot.conf)-- The following is the dovecot.conf file protocols = imap imaps pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/vmail/%d/%n/Maildir ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem namespace private { separator = . prefix = INBOX. inbox = yes } protocol lda { log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster@[mydomainname.com] mail_plugins = sieve global_script_path = /home/vmail/globalsieverc } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { user = root passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } -- Edit 3 (/var/log/mail.log) -- The following is what is in /var/log/mail.log dovecot: master: Dovecot v2.0.13 starting up (core dumps disabled) dovecot: ssl-params: Generating SSL parameters postfix/master[9917]: daemon started -- version 2.8.5, configuration /etc/postfix dovecot: ssl-params: SSL parameters regeneration completed postfix/master[9917]: terminating on signal 15 postfix/master[10196]: daemon started -- version 2.8.5, configuration /etc/postfix dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) postfix/master[2435]: daemon started -- version 2.8.5, configuration /etc/postfix postfix/master[2435]: terminating on signal 15 postfix/master[2965]: daemon started -- version 2.8.5, configuration /etc/postfix

  • svnstat script

    - by Kyle Hodgson
    So I'm building out a shell script to check out all of our relevant svn repositories for analysis in svnstat. I've gotten all of this to work manually, now I'm writing up a bash script in cygwin on my Vista laptop, as I intend to move this to a Linux server at some point. Edit: I gave up on this and wrote a simple .bat script. I'll figure out the Linux deployment some other way. Edit: added the sleep 30 and svn log commands. I can tell now, with the svn log command, that it's not getting to the svn log ... this time, it did Applications, and ran the log, and then check out Database, and froze. I'll put the sleep 30 before and after the log this time. co2.sh #!/bin/bash function checkout { mkdir $1 svn checkout svn://dev-server/$1 $1 svn log --verbose --xml >> svn.log $1 sleep 30 } cd /cygdrive/c/Users/My\ User/Documents/Repos/wc checkout Applications checkout Database checkout WebServer/www.mysite.com checkout WebServer/anotherhost.mysite.com checkout WebServer/AnotherApp checkout WebServer/thirdhost.mysite.com checkout WebServer/fourthhost.mysite.com checkout WebServer/WebServices It works, for the most part - but for some reason it has a tendency to stop working after a few repositories, usually right after finishing a repository before going to the next one. When it fails, it will not recover on its own. I've tried commenting out the svn line, it goes in and creates all the directories just fine when I do that - so its not that. I'm looking for direction as well as direct advice. Cygwin has been very stable for me, but I did start using the native rxvt instead of "bash in a cmd.exe window" recently. I don't think that's the problem, as I've left top on remote systems running all night and rxvt didn't seem to mind. Also I haven't done any bash scripting in cygwin so I suppose this might not be recommended; though I can't see why not. I don't want all of WebServer, hence me only checking out certain folders like that. What I suspect is that something is hanging up the svn checkout. Any ideas here? Edit: this time when I hit ctrl+z to cancel out, I forgot I was on Windows and typed ps to see if the job was still running; and as you can see there are lots of svn processes hanging around... strange.

  • How can I tell Firefox to ignore unprintable characters?

    - by BrianH
    Edit: Summary Apparently the intended character to display in this case is an "en-dash". This page has a table half way down that shows that for the &ndash;, some software will convert the correct hex code of 2013 to 0096. (look at the first row in the table). This answer on Stackoverflow explains that somehow this is a mixup between Windows-1252 and UTF-8 This blog article enforces this: Character 150 (0x96) is the unicode character "START OF GUARDED AREA" in the non-displayed C1 control character range, but in the Windows-1252 encoding it's mapped to to the displayable character 0x2013 "en-dash" (a short dash). Others have struggled with this when producing content, as this answer on Stackoverflow shows how to replace 0x0096 with 0x2013. Google must realize this, because as stated in my original question below, Google's cached version of the Amazon page has &ndash; so it seems they are automatically correcting these mistakes on pages they cache. I have tried setting my encoding to Windows-1252 but that does not help. So now I guess my question is, how can I tell Firefox to ignore unprintable characters like these? Original content below: (Firefox 3.6.13 on Windows XP) Every once in a while I notice an odd character on certain web pages when browsing the web. It is a outline of a box with a 4-digit number inside. And example of a page that has these characters is: http://aws.amazon.com/ec2/#highlights After each section heading (Elastic, Completely Controlled, ...) I see a box with the number "0096" inside. I looked at the cached version on Google, and google has &ndash; in it's place, so I'm guessing I should be seeing a dash there instead of the box with the numbers in it. I have tried changing the character encoding in Firefox but haven't been able to find one that shows these characters correctly. Is there a way to allow Firefox to view these characters? Thanks in advance! Edit - adding a screen shot of the "special" characters: Edit #2 - tried in Ubuntu - new screenshots I logged into my Ubuntu desktop and browsed to the amazon page in Chrome and Firefox. Chrome completely ignores character, even if I inspect or view page source. Firefox in Unbutu displays the character exactly like Firefox on my Windows XP box. I copied the character and played around with it at the command line - here is a screenshot of the results: It looks like I can paste the character into this post as well: `` It is definitely not isolated to Windows XP. I tried setting the character encoding for my terminal to Windows 1252 (from Dennis' comment below), but then it just displays this character as a question mark. I pulled the webpage down with wget and with curl, and both outputs show this characters as: <96> It makes me wonder if this character renders correctly for anyone? It appears webkit just ignores it, my IE6 ignores it, Firefox displays the box with the numbers in it. I would have to imagine the design team at Amazon can see it correctly? It's not a huge deal to get these characters displaying correctly, but it would be nice to know if there is a solution to this.

  • Windows 7 / Ubuntu Dualboot GRUB Problem.

    - by Tek
    I'd like to first say ahead of time that I'm running a RAID-0 Setup. 1.First of all, I'm glad Ubuntu 9.10 installed flawlessly and detected my RAID-0 setup just fine. The issue I'm having now is that I already had Windows 7 installed and made a small 12GB partition for Linux/Swap. I grabbed EasyBCD 2.0 to edit the W7 bootloader and configured it to use dual boot Grub2 because before it didn't even show the option for Ubuntu. The bootloader points to a file made in the windows directory made by EasyBCD called "C:\NST\AutoNeoGrub0.mbr" which is what I'm guessing grub is booting from. After that I got the option for booting Ubuntu. The problem is that it's sending me to the Grub prompt (probably because it's pointing to \NST|AutoNeoGrub0.mbr?), at first I didn't know what to do but I researched and have to type grub commands to manually boot into Ubuntu Linux. Ex: grubroot (hd0,4) grubkernel /boot/vmlinuz-2.6... root=/dev/disk/by-uuid/24624-2424... grubinitrd boot/initrd.img-2.6... grubboot After all that Ubuntu boots just fine, but how do I fix it permanently? Do I need to edit the bootloader manually (since Easy BCD "autoconfigures")? Some insight on this would rock! Also, it sucks to type the actual uuid since it's REALLY long. I tried getting the name of the drive via fdisk -l but since it's raid 0 I'm guessing I can't do that. How can I get a shorter name of the drive? like /dev/sda, /dev/sdb etc? I've also tried to update to the latest GRUB and I got this: Creating config file /etc/default/grub with new version Generating core.img error: cannot seek /dev/sdc' error: cannot seek/dev/sdc' grub-probe: error: no mapping exists for nvidia_dbedfcca5' Auto-detection of a filesystem module failed.

  • Since upgrading to Solaris 11, my ARC size has consistently targeted 119MB, despite having 30GB RAM. What? Why?

    - by growse
    I ran a NAS/SAN box on Solaris 11 Express before Solaris 11 was released. The box is an HP X1600 with an attached D2700. In all, 12x 1TB 7200 SATA disks, 12x 300GB 10k SAS disks in separate zpools. Total RAM is 30GB. Services provided are CIFS, NFS and iSCSI. All was well, and I had a ZFS memory usage graph looking like this: A fairly healthy Arc size of around 23GB - making use of the available memory for caching. However, I then upgraded to Solaris 11 when that came out. Now, my graph looks like this: Partial output of arc_summary.pl is: System Memory: Physical RAM: 30701 MB Free Memory : 26719 MB LotsFree: 479 MB ZFS Tunables (/etc/system): ARC Size: Current Size: 915 MB (arcsize) Target Size (Adaptive): 119 MB (c) Min Size (Hard Limit): 64 MB (zfs_arc_min) Max Size (Hard Limit): 29677 MB (zfs_arc_max) It's targetting 119MB while sitting at 915MB. It's got 30GB to play with. Why? Did they change something? Edit To clarify, arc_summary.pl is Ben Rockwood's, and the relevent lines generating the above stats are: my $mru_size = ${Kstat}->{zfs}->{0}->{arcstats}->{p}; my $target_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c}; my $arc_min_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c_min}; my $arc_max_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c_max}; my $arc_size = ${Kstat}->{zfs}->{0}->{arcstats}->{size}; The Kstat entries are there, I'm just getting odd values out of them. Edit 2 I've just re-measured the arc size with arc_summary.pl - I've verified these numbers with kstat: System Memory: Physical RAM: 30701 MB Free Memory : 26697 MB LotsFree: 479 MB ZFS Tunables (/etc/system): ARC Size: Current Size: 744 MB (arcsize) Target Size (Adaptive): 119 MB (c) Min Size (Hard Limit): 64 MB (zfs_arc_min) Max Size (Hard Limit): 29677 MB (zfs_arc_max) The thing that strikes me is that the Target Size is 119MB. Looking at the graph, it's targeted the exact same value (124.91M according to cacti, 119M according to arc_summary.pl - think the difference is just 1024/1000 rounding issues) ever since Solaris 11 was installed. It looks like the kernel's making zero effort to shift the target size to anything different. The current size is fluctuating as the needs of the system (large) fight with the target size, and it appears equilibrium is between 700 and 1000MB. So the question is now a little more pointed - why is Solaris 11 hard setting my ARC target size to 119MB, and how do I change it? Should I raise the min size to see what happens? I've stuck the output of kstat -n arcstats over at http://pastebin.com/WHPimhfg Edit 3 Ok, weirdness now. I know flibflob mentioned that there was a patch to fix this. I haven't applied this patch yet (still sorting out internal support issues) and I've not applied any other software updates. Last thursday, the box crashed. As in, completely stopped responding to everything. When I rebooted it, it came back up fine, but here's what my graph now looks like. It seems to have fixed the problem. This is proper la la land stuff now. I've literally no idea what's going on. :(

  • Multiple data centers and HTTP traffic: DNS Round Robin is the ONLY way to assure instant fail-over?

    - by vmiazzo
    Hi, Multiple A records pointing to the same domain seem to be used almost exclusively to implement DNS Round Robin as a cheap load balancing technique. The usual warning against DNS RR is that it is not good for high availability. When 1 IP goes down clients will continue to use it for minutes. A load balancer is often suggested as a better choice. Both claims are not completely true: When the traffic is HTTP then, most of the HTML browsers are able to automatically try the next A record if the previous is down, without a new DNS look-up. Read here chapter 3.1 and here. When multiple data centers are involved then, DNS RR is the only option to distribute traffic across them. So, is it true that, with multiple data centers and HTTP traffic, the use of DNS RR is the ONLY way to assure instant fail-over when one data center goes down? Thanks, Valentino Edit: Off course each data center has a local Load Balancer with hot spare. It's OK to sacrifice session affinity for an instant fail-over. AFAIK the only way for a DNS to suggest a data center instead of another is to reply with just the IP (or IPs) associated to that data center. If the data center becomes unreachable then all those IP are also unreachables. This means that, even if smart HTML browsers are able to instantly try another A record , all the attempts will fail until the local cache entry expires and a new DNS lookup is done, fetching the new working IPs (I assume DNS automatically suggests to a new data center when one fail). So, "smart DNS" cannot assure instant fail-over. Conversely a DNS round-robin permits it. When one data center fail, the smart HTML browsers (most of them) instantly try the other cached A records jumping to another (working) data center. So, DNS round-robin doesn't assure session affinity or the lowest RTT but seems to be the only way to assure instant fail-over when the clients are "smart" HTML browsers. Edit 2: Some people suggest TCP Anycast as a definitive solution. In this paper (chapter 6) is explained that Anycast fail-over is related to BGP convergence. For this reason Anycast can employ from 15 minutes to 20 seconds to complete. 20 seconds are possible on networks where the topology was optimized for this. Probably just CDN operators can grant such fast fail-overs. Edit 3:* I did some DNS look-ups and traceroutes (maybe some expert can double check) and: The only CDN using TCP Anycast seems to be CacheFly, other operators like CDN networks and BitGravity use CacheFly. Seems that their edges cannot be used as reverse proxies. Therefore, they cannot be used to grant instant failover. Akamai and LimeLight seems to use geo-aware DNS. But! They return multiple A records. From traceroutes seems that the returned IPs are on the same data center. So, I'm puzzled on how they can offer a 100% SLA when one data center goes down.

  • Long connection times from PHP to MySQL on EC2

    - by Erik Giberti
    I'm having an intermittent issue connecting to a database slave with InnoDB. Intermittently I get connections taking longer than 2 seconds. These servers are hosted on Amazon's EC2. The app server is PHP 5.2/Apache running on Ubuntu. The DB slave is running Percona's XtraDB 5.1 on Ubuntu 9.10. It's using an EBS Raid array for the data storage. We already use skip name resolve and bind to address 0.0.0.0. This is a stub of the PHP code that's failing $tmp = mysqli_init(); $start_time = microtime(true); $tmp-options(MYSQLI_OPT_CONNECT_TIMEOUT, 2); $tmp-real_connect($DB_SERVERS[$server]['server'], $DB_SERVERS[$server]['username'], $DB_SERVERS[$server]['password'], $DB_SERVERS[$server]['schema'], $DB_SERVERS[$server]['port']); if(mysqli_connect_errno()){ $timer = microtime(true) - $start_time; mail($errors_to,'DB connection error',$timer); } There's more than 300Mb available on the DB server for new connections and the server is nowhere near the max allowed (60 of 1,200). Loading on both servers is < 2 on 4 core m1.xlarge instances. Some highlights from the mysql config max_connections = 1200 thread_stack = 512K thread_cache_size = 1024 thread_concurrency = 16 innodb-file-per-table innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 13G Any help on tracing the source of the slowdown is appreciated. [EDIT] I have been updating the sysctl values for the network but they don't seem to be fixing the problem. I made the following adjustments on both the database and application servers. net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_sack = 0 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_fin_timeout = 20 net.ipv4.tcp_keepalive_time = 180 net.ipv4.tcp_max_syn_backlog = 1280 net.ipv4.tcp_synack_retries = 1 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 87380 16777216 [EDIT] Per jaimieb's suggestion, I added some tracing and captured the following data using time. This server handles about 51 queries/second at this the time of day. The connection error was raised once (at 13:06:36) during the 3 minute window outlined below. Since there was 1 failure and roughly 9,200 successful connections, I think this isn't going to produce anything meaningful in terms of reporting.

We had been running the default value (50) and increased it to 150. We also raised the kernel value /proc/sys/net/core/somaxconn (maximum socket connections) to 256 on both the application and database server from the default 128. We did see some elevation in processor utilization as a result but still received connection timeouts.

  • Command-line video editing in Linux (cut, join and preview)

    - by sdaau
    I have rather simple editing needs - I need to cut up some videos, maybe insert some PNGs in between them, and join these videos (don't need transitions, effects, etc.). Basically, pitivi would do what I want - except, I use 640x480 30 fps AVI's from a camera, and as soon as I put in over a couple of minutes of that kind of material, pitivi starts freezing on preview, and thus becomes unusable. So, I started looking for a command line tool for Linux; I guess only ffmpeg (command line - Using ffmpeg to cut up video - Super User) and mplayer (Sam - Edit video file with mencoder under linux) are so far candidates, but I cannot find examples of the use I have in mind.   Basically, I'd imagine there's an encoder and player tools (like ffmpeg vs ffplay; or mencoder vs mplayer) - such that, to begin with, the edit sequence could be specified directly on the command line, preferably with frame resolution - a pseudocode would look like: videnctool -compose --file=vid1.avi --start=00:00:30:12 --end=00:01:45:00 --file=vid2.avi --start=00:05:00:00 --end=00:07:12:25 --file=mypicture.png --duration=00:00:02:00 --file=vid3.avi --start=00:02:00:00 --end=00:02:45:10 --output=editedvid.avi ... or, it could have a "playlist" text file, like: vid1.avi 00:00:30:12 00:01:45:00 vid2.avi 00:05:00:00 00:07:12:25 mypicture.png - 00:00:02:00 vid3.avi 00:02:00:00 00:02:45:10 ... so it could be called with videnctool -compose --playlist=playlist.txt --output=editedvid.avi The idea here would be that all of the videos are in the same format - allowing the tool to avoid transcoding, and just do a "raw copy" instead (as in mencoder's copy codec: "-oac copy -ovc copy") - or in lack of that, uncompressed audio/video would be OK (although it would eat a bit of space). In the case of the still image, the tool would use the encoding set by the video files.   The thing is, I can so far see that mencoder and ffmpeg can operate on individual files; e.g. cut a single section from a single file, or join files (mencoder also has Edit Decision Lists (EDL), which can be used to do frame-exact cutting - so you can define multiple cut regions, but it's again attributed to a single file). Which implies I have to work on cutting pieces first from individual files first (each of which would demand own temporary file on disk), and then joining them in a final video file. I would then imagine, that there is a corresponding player tool, which can read the same command line option format / playlist file as the encoding tool - except it will not generate an output file, but instead play the video; e.g. in pseudocode: vidplaytool --playlist=playlist.txt --start=00:01:14 --end=00:03:13 ... and, given there's enough memory, it would generate a low-res video preview in RAM, and play it back in a window, while offering some limited interaction ( like mplayer's keyboard shortcuts for play, pause, rewind, step frame). Of course, I'd imagine the start and end times to refer to the entire playlist, and include any file that may end up in that region in the playlist. Thus, the end result of all this would be: command line operation; no temporary files while doing the editing - and also no temporary files (nor transcoding) when rendering final output... which I myself think would be nice. So, while I think that all of the above may be a bit of a stretch - does there exist anything that would approximate the workflow described above?

  • Publishing an Excel spreadsheet using Microsoft SBS 2008 to a web page that is viewable by mobile ph

    - by Dave Heath
    I am getting well out of my “superuser” depth here and would love some support. At work we have an Excel workbook (*.xls format circa Office 2003) which maintains our “engineers” timesheet. This handles what events we are doing across the year and how many “work units” it is. As far as a workbook goes, it is fairly simple with just a few =SUM(range) cells and some linked across sheets (12 sheets, one for each month) It is stored on a server, in a folder that provides “management” with full access and “engineers” with read-only access. The workbook itself is read-only for “engineers” and full access for “management”. I think these permissions are controlled through Active Directory. The workbook is protected with a password, assumingly to allow “management” to edit it even if they are working at a terminal logged in as an “engineer”. This protection prevents “engineers” from going to certain cells to see formulae and therefore editing them. The workbook has a macro which saves and closes it ten minutes after opening. This is to stop other “management” from being locked out by any one person who has logged in with editing privileges. I hope this is making sense to someone... :S Now then, we have Microsoft Small Business Server 2008. We have a shiny new web-based login for when we are offsite so we can get to Exchange webmail and our internal site (which uses Sharepoint 3.0). “Management” would like to be able to publish this timesheet automatically after changes (they don’t want to have to do anything different to what they are currently doing) so that using an iPhone “engineers” can check on it while out of the office. I am currently having a look at “Excel Services” for Office 2007 on TechNet but I am not sure if I am running down the right garden path at the moment. < EDIT This seems to suggest that I have to have Sharepoint Server 2007, with no mention of Sharepoint 3.0... ... "MOSS builds on WSS by adding both core features as well as end user web parts" - Wikipedia entry for Microsoft Office SharePoint Server (MOSS) this is not good news... "...and using the ASP.NET APIs, web parts can be written to extend the functionality of WSS." Wikipedia entry for Windows Sharepoint Services. Could this bring back what I need? Is this good news? Do I need to start learning ASP.NET? This link here implies that we need MOSS to do what I want and the bosses say we aint' getting it. http://serverfault.com/questions/20198/what-is-some-cool-things-you-can-do-with-sharepoint-2007/22128#22128 Back to the drawing board. < /EDIT Please could someone suggest some “further reading” for me to help point me in the right direction or to put me back on the right track. Many thanks. I will try to keep this up to date with how I get on.

  • AWS Load balancer connection reset

    - by joshmmo
    I have an ELB set up with two instances. The issue I have with it is that when I do not add www. to it, the ELB just hangs. This is some info I get when I spider with wget: Spider mode enabled. Check if remote file exists. --2013-06-20 13:40:54-- http://learning.example.com/ Resolving learning.example.com... 54.xxx.x.x53, 50.xx.xxx.x71 Connecting to learning.example.com|54.xxx.x.x53|:80... connected. HTTP request sent, awaiting response... No data received. Retrying. when I add www. it works great. I have a GoDaddy SSL cert that I added to the listener section that covers 3 domains, www.learning.example.com, files.learning.example.com and learning.example.com. These are my listener settings: - HTTP 80 HTTPS 443 N/A N/A - SSL 443 SSL 443 Change canvasNew (Change) My EC2 instances are running apache2 on Ubuntu 12.04. I will be happy to post my vhosts file if needed. However, when I ran the server with the domains pointing to just one EC2 instance things worked fine. How can I fix this issue for learning.example.com? Why does www work just fine? A second question would be what is the difference between instance protocol and load balancer protocol? EDIT: Here are the dig results for learning.example.com from yesterday. I changed the DNS entry to point to one instance to make sure it was the elb. When I switch it back I will do it for www.learning.example.com ; <<>> DiG 9.9.1-P2 <<>> learning.example.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20210 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;learning.example.com.

It's running great. www and the non-www url work perfectly fine. Its only when I switch things to the ELB that learning.example.com hangs and www.learning.example.com works. Hopefully you can get some ideas flowing.

  • iptables rule(s) to send openvpn traffic from clients over an sshuttle tunnel?

    - by Sam Martin
    I have an Ubuntu 12.04 box with OpenVPN. The VPN is working as expected -- clients can connect, browse the Web, etc. The OpenVPN server IP is 10.8.0.1 on tun0. On that same box, I can use sshuttle to tunnel into another network to access a Web server on 10.10.0.9. sshuttle does its magic using the following iptables commands: iptables -t nat -N sshuttle-12300 iptables -t nat -F sshuttle-12300 iptables -t nat -I OUTPUT 1 -j sshuttle-12300 iptables -t nat -I PREROUTING 1 -j sshuttle-12300 iptables -t nat -A sshuttle-12300 -j REDIRECT --dest 10.10.0.0/24 -p tcp --to-ports 12300 -m ttl ! --ttl 42 iptables -t nat -A sshuttle-12300 -j RETURN --dest 127.0.0.0/8 -p tcp Is it possible to forward traffic from OpenVPN clients over the sshuttle tunnel to the remote Web server? I'd ultimately like to be able to set up any complicated tunneling on the server, and have relatively "dumb" clients (iPad, etc.) be able to access the remote servers via OpenVPN. Below is a basic diagram of the scenario: [Edit: added output from the OpenVPN box] $ sudo iptables -nL -v -t nat Chain PREROUTING (policy ACCEPT 1498 packets, 252K bytes) pkts bytes target prot opt in out source destination 1512 253K sshuttle-12300 all -- * * 0.0.0.0/0 0.0.0.0/0 Chain INPUT (policy ACCEPT 322 packets, 58984 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 584 packets, 43241 bytes) pkts bytes target prot opt in out source destination 587 43421 sshuttle-12300 all -- * * 0.0.0.0/0 0.0.0.0/0 Chain POSTROUTING (policy ACCEPT 589 packets, 43595 bytes) pkts bytes target prot opt in out source destination 1175 76298 MASQUERADE all -- * eth0 10.8.0.0/24 0.0.0.0/0 Chain sshuttle-12300 (2 references) pkts bytes target prot opt in out source destination 17 1076 REDIRECT tcp -- * * 0.0.0.0/0 10.10.0.0/24 TTL match TTL != 42 redir ports 12300 0 0 RETURN tcp -- * * 0.0.0.0/0 127.0.0.0/8 $ sudo iptables -nL -v -t filter Chain INPUT (policy ACCEPT 97493 packets, 30M bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 131K 109M ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 1370 89160 ACCEPT all -- * * 10.8.0.0/24 0.0.0.0/0 0 0 REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable [Edit 2: more OpenVPN server output] $ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 [Edit 3: still more debug output] IP forwarding appears to be enabled correctly on the OpenVPN server: # find /proc/sys/net/ipv4/conf/ -name forwarding -ls -execdir cat {} \; 18926 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/all/forwarding 1 18954 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/default/forwarding 1 18978 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/eth0/forwarding 1 19003 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/lo/forwarding 1 19028 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/tun0/forwarding 1 Client routing table: $ netstat -r Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire 0/1 10.8.0.5 UGSc 8 48 tun0 default 192.168.1.1 UGSc 2 1652 en1 10.8.0.1/32 10.8.0.5 UGSc 1 0 tun0 10.8.0.5 10.8.0.6 UHr 13 0 tun0 10.10.0/24 10.8.0.5 UGSc 0 0 tun0 <snip> Traceroute from client: $ traceroute 10.10.0.9 traceroute to 10.10.0.9 (10.10.0.9), 64 hops max, 52 byte packets 1 10.8.0.1 (10.8.0.1) 5.403 ms 1.173 ms 1.086 ms 2 192.168.1.1 (192.168.1.1) 4.693 ms 2.110 ms 1.990 ms 3 l100.my-verizon-garbage (client-ext-ip) 7.453 ms 7.089 ms 6.248 ms 4 * * * 5 10.10.0.9 (10.10.0.9) 14.915 ms !N * 6.620 ms !N

  • AMD Catalyst 13.9 installation failure

    - by Simon Verbeke
    Earlier today I installed Windows 8.1, and when I wanted to go into Catalyst Control Center, I noticed some odd error of CCC not being able to display options. I then figured I needed a driver update, so I downloaded the latest drivers, version 13.9, and tried to install them. While it was trying to install the display drivers, I got a blue screen. Tried again and got the same. Then I used an uninstall tool from AMD to remove all traces of my old drivers and tried to install the new drivers. Again, a blue screen. This is all I could think of to try. Would anyone know some other things I can try? EDIT: thought I might want to include the log entry for the crash: - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> - <System> <Provider Name="Microsoft-Windows-WER-SystemErrorReporting" Guid="{ABCE23E7-DE45-4366-8631-84FA6C525952}" EventSourceName="BugCheck" /> <EventID Qualifiers="16384">1001</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2013-10-19T20:59:25.000000000Z" /> <EventRecordID>26587</EventRecordID> <Correlation /> <Execution ProcessID="0" ThreadID="0" /> <Channel>System</Channel> <Computer>Simon-PC</Computer> <Security /> </System> - <EventData> <Data Name="param1">0x0000007e (0xffffffffc0000005, 0xfffff80002a86dca, 0xffffd00025f250e8, 0xffffd00025f248f0)</Data> <Data Name="param2">C:\WINDOWS\MEMORY.DMP</Data> <Data Name="param3">101913-8953-01</Data> </EventData> </Event> Another edit: As it turns out, the graphics card isn't showing up any more in the device manager. But as far as I can tell, it is still working (the fans are spinning and my screen is plugged into that graphics card). This is solved. it appears that my graphics card is now running with a default windows driver. I also tried the forced method mentioned here: AMD Graphics Drivers won't install properly . But I still get a BSOD. Third edit: Slight succes! Managed to install version 13.4. Everything appears to be working fine now. I think I'm just going to skip version 13.9.

  • NoSQL with RavenDB and ASP.NET MVC - Part 1

    - by shiju
     A while back, I have blogged NoSQL with MongoDB, NoRM and ASP.NET MVC Part 1 and Part 2 on how to use MongoDB with an ASP.NET MVC application. The NoSQL movement is getting big attention and RavenDB is the latest addition to the NoSQL and document database world. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed  by Ayende Rahien.  Raven stores schema-less JSON documents, allow you to define indexes using Linq queries and focus on low latency and high performance. RavenDB is .NET focused document database which comes with a fully functional .NET client API  and supports LINQ. RavenDB comes with two components, a server and a client API. RavenDB is a REST based system, so you can write your own HTTP cleint API. As a .NET developer, RavenDB is becoming my favorite document database. Unlike other document databases, RavenDB is supports transactions using System.Transactions. Also it's supports both embedded and server mode of database. You can access RavenDB site at http://ravendb.netA demo App with ASP.NET MVCLet's create a simple demo app with RavenDB and ASP.NET MVC. To work with RavenDB, do the following steps. Go to http://ravendb.net/download and download the latest build.Unzip the downloaded file.Go to the /Server directory and run the RavenDB.exe. This will start the RavenDB server listening on localhost:8080You can change the port of RavenDB  by modifying the "Raven/Port" appSetting value in the RavenDB.exe.config file.When running the RavenDB, it will automatically create a database in the /Data directory. You can change the directory name data by modifying "Raven/DataDirt" appSetting value in the RavenDB.exe.config file.RavenDB provides a browser based admin tool. When the Raven server is running, You can be access the browser based admin tool and view and edit documents and index using your browser admin tool. The web admin tool available at http://localhost:8080The below is the some screen shots of web admin tool     Working with ASP.NET MVC  To working with RavenDB in our demo ASP.NET MVC application, do the following steps Step 1 - Add reference to Raven Cleint API In our ASP.NET MVC application, Add a reference to the Raven.Client.Lightweight.dll from the Client directory. Step 2 - Create DocumentStoreThe document store would be created once per application. Let's create a DocumentStore on application start-up in the Global.asax.cs. documentStore = new DocumentStore { Url = "http://localhost:8080/" }; documentStore.Initialise(); The above code will create a Raven DB document store and will be listening the server locahost at port 8080    Step 3 - Create DocumentSession on BeginRequest   Let's create a DocumentSession on BeginRequest event in the Global.asax.cs. We are using the document session for every unit of work. In our demo app, every HTTP request would be a single Unit of Work (UoW). BeginRequest += (sender, args) =>   HttpContext.Current.Items[RavenSessionKey] = documentStore.OpenSession(); Step 4 - Destroy the DocumentSession on EndRequest  EndRequest += (o, eventArgs) => {     var disposable = HttpContext.Current.Items[RavenSessionKey] as IDisposable;     if (disposable != null)         disposable.Dispose(); };  At the end of HTTP request, we are destroying the DocumentSession  object.The below  code block shown all the code in the Global.asax.cs  private const string RavenSessionKey = "RavenMVC.Session"; private static DocumentStore documentStore;   protected void Application_Start() { //Create a DocumentStore in Application_Start //DocumentStore should be created once per application and stored as a singleton. documentStore = new DocumentStore { Url = "http://localhost:8080/" }; documentStore.Initialise(); AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); //DI using Unity 2.0 ConfigureUnity(); }   public MvcApplication() { //Create a DocumentSession on BeginRequest   //create a document session for every unit of work BeginRequest += (sender, args) =>     HttpContext.Current.Items[RavenSessionKey] = documentStore.OpenSession(); //Destroy the DocumentSession on EndRequest EndRequest += (o, eventArgs) => { var disposable = HttpContext.Current.Items[RavenSessionKey] as IDisposable; if (disposable != null) disposable.Dispose(); }; }   //Getting the current DocumentSession public static IDocumentSession CurrentSession {   get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; } }  We have setup all necessary code in the Global.asax.cs for working with RavenDB. For our demo app, Let’s write a domain class  public class Category {       public string Id { get; set; }       [Required(ErrorMessage = "Name Required")]     [StringLength(25, ErrorMessage = "Must be less than 25 characters")]     public string Name { get; set;}     public string Description { get; set; }   } We have created simple domain entity Category. Let's create repository class for performing CRUD operations against our domain entity Category.  public interface ICategoryRepository {     Category Load(string id);     IEnumerable<Category> GetCategories();     void Save(Category category);     void Delete(string id);       }    public class CategoryRepository : ICategoryRepository {     private IDocumentSession session;     public CategoryRepository()     {             session = MvcApplication.CurrentSession;     }     //Load category based on Id     public Category Load(string id)     {         return session.Load<Category>(id);     }     //Get all categories     public IEnumerable<Category> GetCategories()     {         var categories= session.LuceneQuery<Category>()                 .WaitForNonStaleResults()             .ToArray();         return categories;       }     //Insert/Update category     public void Save(Category category)     {         if (string.IsNullOrEmpty(category.Id))         {             //insert new record             session.Store(category);         }         else         {             //edit record             var categoryToEdit = Load(category.Id);             categoryToEdit.Name = category.Name;             categoryToEdit.Description = category.Description;         }         //save the document session         session.SaveChanges();     }     //delete a category     public void Delete(string id)     {         var category = Load(id);         session.Delete<Category>(category);         session.SaveChanges();     }        } For every CRUD operations, we are taking the current document session object from HttpContext object. session = MvcApplication.CurrentSession; We are calling the static method CurrentSession from the Global.asax.cs public static IDocumentSession CurrentSession {     get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; } }  Retrieve Entities  The Load method get the single Category object based on the Id. RavenDB is working based on the REST principles and the Id would be like categories/1. The Id would be created by automatically when a new object is inserted to the document store. The REST uri categories/1 represents a single category object with Id representation of 1.   public Category Load(string id) {    return session.Load<Category>(id); } The GetCategories method returns all the categories calling the session.LuceneQuery method. RavenDB is using a lucen query syntax for querying. I will explain more details about querying and indexing in my future posts.   public IEnumerable<Category> GetCategories() {     var categories= session.LuceneQuery<Category>()             .WaitForNonStaleResults()         .ToArray();     return categories;   } Insert/Update entityFor insert/Update a Category entity, we have created Save method in repository class. If  the Id property of Category is null, we call Store method of Documentsession for insert a new record. For editing a existing record, we load the Category object and assign the values to the loaded Category object. The session.SaveChanges() will save the changes to document store.  //Insert/Update category public void Save(Category category) {     if (string.IsNullOrEmpty(category.Id))     {         //insert new record         session.Store(category);     }     else     {         //edit record         var categoryToEdit = Load(category.Id);         categoryToEdit.Name = category.Name;         categoryToEdit.Description = category.Description;     }     //save the document session     session.SaveChanges(); }  Delete Entity  In the Delete method, we call the document session's delete method and call the SaveChanges method to reflect changes in the document store.  public void Delete(string id) {     var category = Load(id);     session.Delete<Category>(category);     session.SaveChanges(); }  Let’s create ASP.NET MVC controller and controller actions for handling CRUD operations for the domain class Category  public class CategoryController : Controller { private ICategoryRepository categoyRepository; //DI enabled constructor public CategoryController(ICategoryRepository categoyRepository) {     this.categoyRepository = categoyRepository; } public ActionResult Index() {         var categories = categoyRepository.GetCategories();     if (categories == null)         return RedirectToAction("Create");     return View(categories); }   [HttpGet] public ActionResult Edit(string id) {     var category = categoyRepository.Load(id);         return View("Save",category); } // GET: /Category/Create [HttpGet] public ActionResult Create() {     var category = new Category();     return View("Save", category); } [HttpPost] public ActionResult Save(Category category) {     if (!ModelState.IsValid)     {         return View("Save", category);     }           categoyRepository.Save(category);         return RedirectToAction("Index");     }        [HttpPost] public ActionResult Delete(string id) {     categoyRepository.Delete(id);     var categories = categoyRepository.GetCategories();     return PartialView("CategoryList", categories);      }        }  RavenDB is an awesome document database and I hope that it will be the winner in .NET space of document database world.  The source code of demo application available at http://ravenmvc.codeplex.com/

  • Android - creating a custom preferences activity screen

    - by Bill Osuch
    Android applications can maintain their own internal preferences (and allow them to be modified by users) with very little coding. In fact, you don't even need to write an code to explicitly save these preferences, it's all handled automatically! Create a new Android project, with an intial activity title Main. Create two more activities: ShowPrefs, which extends Activity Set Prefs, which extends PreferenceActivity Add these two to your AndroidManifest.xml file: <activity android:name=".SetPrefs"></activity> <activity android:name=".ShowPrefs"></activity> Now we'll work on fleshing out each activity. First, open up the main.xml layout file and add a couple of buttons to it: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"> <Button android:text="Edit Preferences"    android:id="@+id/prefButton"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center_horizontal"/> <Button android:text="Show Preferences"    android:id="@+id/showButton"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center_horizontal"/> </LinearLayout> Next, create a couple button listeners in Main.java to handle the clicks and start the other activities: Button editPrefs = (Button) findViewById(R.id.prefButton);       editPrefs.setOnClickListener(new View.OnClickListener() {              public void onClick(View view) {                  Intent myIntent = new Intent(view.getContext(), SetPrefs.class);                  startActivityForResult(myIntent, 0);              }      });           Button showPrefs = (Button) findViewById(R.id.showButton);      showPrefs.setOnClickListener(new View.OnClickListener() {              public void onClick(View view) {                  Intent myIntent = new Intent(view.getContext(), ShowPrefs.class);                  startActivityForResult(myIntent, 0);              }      }); Now, we'll create the actual preferences layout. You'll need to create a file called preferences.xml inside res/xml, and you'll likely have to create the xml directory as well. Add the following xml: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> </PreferenceScreen> First we'll add a category, which is just a way to group similar preferences... sort of a horizontal bar. Add this inside the PreferenceScreen tags: <PreferenceCategory android:title="First Category"> </PreferenceCategory> Now add a Checkbox and an Edittext box (inside the PreferenceCategory tags): <CheckBoxPreference    android:key="checkboxPref"    android:title="Checkbox Preference"    android:summary="This preference can be true or false"    android:defaultValue="false"/> <EditTextPreference    android:key="editTextPref"    android:title="EditText Preference"    android:summary="This allows you to enter a string"    android:defaultValue="Nothing"/> The key is how you will refer to the preference in code, the title is the large text that will be displayed, and the summary is the smaller text (this will make sense when you see it). Let's say we've got a second group of preferences that apply to a different part of the app. Add a new category just below the first one: <PreferenceCategory android:title="Second Category"> </PreferenceCategory> In there we'll a list with radio buttons, so add: <ListPreference    android:key="listPref"    android:title="List Preference"    android:summary="This preference lets you select an item in a array"    android:entries="@array/listArray"    android:entryValues="@array/listValues" /> When complete, your full xml file should look like this: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">  <PreferenceCategory android:title="First Category"> <CheckBoxPreference    android:key="checkboxPref"    android:title="Checkbox Preference"    android:summary="This preference can be true or false"    android:defaultValue="false"/> <EditTextPreference    android:key="editTextPref"    android:title="EditText Preference"    android:summary="This allows you to enter a string"    android:defaultValue="Nothing"/>  </PreferenceCategory>  <PreferenceCategory android:title="Second Category">   <ListPreference    android:key="listPref"    android:title="List Preference"    android:summary="This preference lets you select an item in a array"    android:entries="@array/listArray"    android:entryValues="@array/listValues" />  </PreferenceCategory> </PreferenceScreen> However, when you try to save it, you'll get an error because you're missing your array definition. To fix this, add a file called arrays.xml in res/values, and paste in the following: <?xml version="1.0" encoding="utf-8"?> <resources>  <string-array name="listArray">      <item>Value 1</item>      <item>Value 2</item>      <item>Value 3</item>  </string-array>  <string-array name="listValues">      <item>1</item>      <item>2</item>      <item>3</item>  </string-array> </resources> Finally (for the preferences screen at least...) add the code that will display the preferences layout to the SetPrefs.java file:  @Override     public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      addPreferencesFromResource(R.xml.preferences);      } OK, so now we've got an activity that will set preferences, and save them without the need to write custom save code. Let's throw together an activity to work with the saved preferences. Create a new layout called showpreferences.xml and give it three Textviews: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"> <TextView   android:id="@+id/textview1"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview1"/> <TextView   android:id="@+id/textview2"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview2"/> <TextView   android:id="@+id/textview3"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview3"/> </LinearLayout> Open up the ShowPrefs.java file and have it use that layout: setContentView(R.layout.showpreferences); Then add the following code to load the DefaultSharedPreferences and display them: SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);    TextView text1 = (TextView)findViewById(R.id.textview1); TextView text2 = (TextView)findViewById(R.id.textview2); TextView text3 = (TextView)findViewById(R.id.textview3);    text1.setText(new Boolean(prefs.getBoolean("checkboxPref", false)).toString()); text2.setText(prefs.getString("editTextPref", "<unset>"));; text3.setText(prefs.getString("listPref", "<unset>")); Fire up the application in the emulator and click the Edit Preferences button. Set various things, click the back button, then the Edit Preferences button again. Notice that your choices have been saved.   Now click the Show Preferences button, and you should see the results of what you set:   There are two more preference types that I did not include here: RingtonePreference - shows a radioGroup that lists your ringtones PreferenceScreen - allows you to embed a second preference screen inside the first - it opens up a new set of preferences when clicked

  • SSIS packages incompatibilities between SSIS 2008 and SSIS 2008 R2

    - by Marco Russo (SQLBI)
    When you install SQL 2008 R2 workstation components you get a newer version of BIDS (BI Developer Studio, included in the workstation components) that replaces BIDS 2008 version (BIDS 2005 still live side-by-side). Everything would be good if you can use the newer version to edit any 2008 AND 2008R2 project. SSIS editor doesn't offer a way to set the "compatibility level" of the package, becuase it is almost all unchanged. However, if a package has an ADO.NET Destination Adapter, there is a difference...(read more)
