APC PHP cache size does not exceed 32MB, even though settings allow for more

- by hardy101

I am setting up APC (v 3.1.9) on a high-traffic WordPress installation on CentOS 6.0 64 bit. I have figured out many of the quirks with APC, but something is still not quite right. No matter what settings I change, APC never actually caches more than 32MB. I'm trying to bump it up to 256 MB. 32MB is a default amount for apc.shm_size, so I am wondering if it's stuck there somehow. I have run the following echo '2147483648' > /proc/sys/kernel/shmmax to increase my system's shared memory to 2G (half of my 4G box). Then ran ipcs -lm which returns ------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 2097152 max total shared memory (kbytes) = 8388608 min seg size (bytes) = 1 Also made a change in /etc/sysctl.conf then ran sysctl -p to make the settings stick on the server. Rebooted, too, for good measure. In my APC settings, I have mmap enabled (which happens by default in recent versions of APC). php.ini looks like: apc.stat=0 apc.shm_size="256M" apc.max_file_size="10M" apc.mmap_file_mask="/tmp/apc.XXXXXX" apc.ttl="7200" I am aware that mmap mode will ignore references to apc.shm_segments, so I have left it out with default 1. phpinfo() indicates the following about APC: Version 3.1.9 APC Debugging Disabled MMAP Support Enabled MMAP File Mask /tmp/apc.bPS7rB Locking type pthread mutex Locks Serialization Support php Revision $Revision: 308812 $ Build Date Oct 11 2011 22:55:02 Directive Local Value apc.cache_by_default On apc.canonicalize O apc.coredump_unmap Off apc.enable_cli Off apc.enabled On On apc.file_md5 Off apc.file_update_protection 2 apc.filters no value apc.gc_ttl 3600 apc.include_once_override Off apc.lazy_classes Off apc.lazy_functions Off apc.max_file_size 10M apc.mmap_file_mask /tmp/apc.bPS7rB apc.num_files_hint 1000 apc.preload_path no value apc.report_autofilter Off apc.rfc1867 Off apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 256M apc.slam_defense On apc.stat Off apc.stat_ctime Off apc.ttl 7200 apc.use_request_time On apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock On apc.php reveals the following graph, no matter how long the server runs (cache size fluctuates and hovers at just under 32MB. See image http://i.stack.imgur.com/2bwMa.png You can see that the cache is trying to allocate 256MB, but the brown piece of the pie keeps getting recycled at 32MB. This is confirmed as refreshing the apc.php page shows cached file counts that move up and down (implying that the cache is not holding onto all of its files). Does anyone have an idea of how to get APC to use more than 32 MB for its cache size?? **Note that the identical behavior occurs for eaccelerator, xcache, and APC. I read here: http://www.litespeedtech.com/support/forum/archive/index.php/t-5072.html that suEXEC could cause this problem.

How can I remove old log entries from a log file and archive them somewhere else in Linux?

- by Mike B

CentOS 4.x I apologize in advance if this is not the appropriate place to ask this question. It pertains to a linux server / IT admin task. I've got a log file on an old CentOS 4.x server and I want to remove log entries older than a certain date and place them in a new file for archive. Here's an example of the log format: 2012-06-07 22:32:01,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:32:03,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:32:04,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123| 2012-06-07 22:32:10,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:32:12,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:32:15,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123| 2012-06-07 22:32:40,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:32:58,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:33:01,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123| 2012-06-07 22:33:01,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123|blah blah blah 2012-06-07 22:33:02,289 ABC:0|Foo|Foo2|4.4|1234|Some Event|123| Essentially, I'm looking for a one-liner that will do the following: Find any events older than a provided YYYY-MM-DD and remove them from the primary log file. Take the deleted events from step 1 and put them in a new log file (Optional) Compress the new archive log file holding the deleted events. I'm aware that there are log rotate tools that do this but this should just be a one-time task so I'd prefer not to set that up. Additional notes: If the date part it tricky or too resource intensive, an alternative would be to just keep the last X number of lines and move the rest. I was originally thinking of something like tail -n 10000 > newfile.txt but that would mean moving the "good" logs to a new file and then doing a name swap... and then I'd still need to remove the "good" entries from the archive. This particular log file is pretty large (1 GB) so I'd prefer the task to be as resource and time efficient as possible. The extra pipes in the log concern me and I'm not sure if I'd need extra protection in the commands to avoid that from causing problems.

Rails /tmp/cache/assets permissions issue using Debian virtual machine hosted on OS X Lion

- by Jim

I am running Parallels Desktop 7 on OS X Lion. I have a VM with Debian installed, and inside that VM I setup a Rails development environment. I am using Parallels Tools to share out my OS X home directory to the VM - the goal here is to run the Rails server on the VM, but host the files on OS X (so they are automatically backed up, and so I can use tools like Textmate to develop with). Everything seems to work with the shared directory - my Debian user can read, write, and execute files. However, when I cloned a recent Rails project from Git, I got an error message when it tried to compile the CSS assets. My symptoms are exactly the same as in the question: http://stackoverflow.com/questions/7556774/rails-sprocket-error-compiling-css-assest-chown-issue I believe this is permissions-based, but it is really weird. My entire Rails project directory has permissions set to 777 and my Debian user owns it. If I navigate into /tmp/cache/assets, those permissions are the same. However, the three-character directories Rails is creating (DCE, DA1, D05, etc...) are being created without write permissions! If I refresh the Rails page a few times, about 4 or 5 (with Rails creating new three-character directories every time), eventually it will create one of the directories with the proper 777 permissions and everything will work! This will persist until I make a change to the CSS files and it has to recompile. Does anyone have any idea what might be going on here? I can't fathom why it is creating temp directories with incorrect permissions, or why after a few refreshes the good permissions kick in and it works... It definitely seems to be an issue with the share, since if I move the project into a different directory on the VM, it seems to work fine. On the OS X side, I've given the shared folder 777 permissions as well, but no dice...any ideas? Update I've found that the number of times I need to refresh before it works is not random - it has to do with how many assets are being compiled. For example, if I edit one of my CSS files, and there are four CSS files in the app/assets/stylesheets directory, I have to refresh four times before the app will finally work without the operation not permitted error...

Sharing files between multiple sites using only desktop software

- by perlyking

Our organisation has three sites; a head office, where the master copies of company files are stored, plus two branch offices using only workstations and a NAS or two. Currently we're talking about <10GB. At the main office, we have no admin access to the file server, as this is entirely controlled by the larger institution where we are located. For the same reason, we have no VPN remote access to this network. Instead, we simply have access to a network share using over a Novell LAN. Question: how can we share files between offices in way that minimises latency, i.e. that gives us a mirror of the main network share at each site? (There is little likelihood of concurrent editing, and we can live with the odd file conflict now and again). Up to now branch office staff have had to use GotoMyPC-type solutions to remotely access files held at the main office. Or email. I was hoping to use Google Drive on a dedicated workstation at each office to sync the contents of the network share (head office) or NAS (branch offices) via the cloud, but at my last attempt (29 Jun '12), the Google Drive installer would not allow me to designate the remote network share as the "target" folder. (I chose Google Drive over Drobbox et al. as we already use GMail for corporate mail) The next idea was to use a designated workstation at head office to mirror the network share to a local drive, then use Google Drive to push that to the cloud. This seems a step too far. Nor do I have any good ideas about how to achieve this network/local mirroring, as we can't, for example, install the rsync daemon on the server. I do not want to use Google Drive locally on each workstation as this will inconvenience users, and more importantly, move files off the backed-up, well-maintained (UPS, RAID etc) network share at head office. Our budget is only in the £100's. Should we perhaps just ditch the head office server and use something like JungleDisk? At least this presents the user with what appears to be a mapped drive.

New-ManagedContentSettings - not working properly under Exchange 2010

- by mfinni

I have a client that is divesting a business unit into a new AD forest, Exchange org, etc. We're using Quest tools to migrate users and mailboxes. However, I have to build the new infrastructure to match the old one. In the old one, we're using Managed Folder Mailbox Policies to limit (or allow) retention. They started with Exchange 2007 and never upgraded to Retention Policies; oh well. So, in the old environment, when you use a 2007 server to define a new Managed Content Setting, you can pick "Email" from the dropdown for MessageClass. This is a display name; the actual MessageClass values are thus: MessageClass : IPM.Note;IPM.Note.AS/400 Move Notification Form v1.0;IPM.Note.Delayed;IPM.Note.Exchange.ActiveSync.Report;IPM.Note.JournalReport.Msg;IPM.Note.JournalReport.Tnef;IPM.Note.Microsoft.Missed.Voice;IPM.Note.Rules.OofTemplate.Microsoft;IPM.Note.Rules.ReplyTemplate.Microsoft;IPM.Note.Secure.Sign;IPM.Note.SMIME;IPM.Note.SMIME.MultipartSigned;IPM.Note.StorageQuotaWarning;IPM.Note.StorageQuotaWarning.Warning;IPM.Notification.Meeting.Forward;IPM.Outlook.Recall;IPM.Recall.Report.Success;IPM.Schedule.Meeting.*;REPORT.IPM.Note.NDR If I take that and try to mangle it into a new cmdlet for Ex2010 in my new environment here's what I get New-ManagedContentSettings -Name "Delete Messages older then 90 days" -FolderName "Entire Mailbox" -RetentionEnabled $True -AgeLimitForRetention 90 -TriggerForRetention WhenDelivered -RetentionAction DeleteAndAllowRecovery -MessageClass "IPM.Note","IPM.Note.AS/400MoveNotificationFormv1.0","IPM.Note.Delayed","IPM.Note.Exchange.ActiveSync.Report","IPM.Note.JournalReport.Msg","IPM.Note.JournalReport.Tnef","IPM.Note.Microsoft.Missed.Voice","IPM.Note.Rules.OofTemplate.Microsoft","IPM.Note.Rules.ReplyTemplate.Microsoft","IPM.Note.Secure.Sign","IPM.Note.SMIME","IPM.Note.SMIME.MultipartSigned","IPM.Note.StorageQuotaWarning","IPM.Note.StorageQuotaWarning.Warning","IPM.Notification.Meeting.Forward","IPM.Outlook.Recall","IPM.Recall.Report.Success","IPM.Schedule.Meeting.*","REPORT.IPM.Note.NDR" -whatif Invoke-Command : Cannot bind parameter 'MessageClass' to the target. Exception setting "MessageClass": "The length of t he property is too long. The maximum length is 255 and the length of the value provided is 518." At C:\Users\MFinnigan.sa\AppData\Roaming\Microsoft\Exchange\RemotePowerShell\pfexcas02.fve.ad.5ssl.com\pfexcas02.fve.ad .5ssl.com.psm1:28204 char:29 + $scriptCmd = { & <<<< $script:InvokeCommand ` + CategoryInfo : WriteError: (:) [New-ManagedContentSettings], ParameterBindingException + FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.Exchange.Management.SystemConfigurationTasks.NewManaged ContentSettings So, the config object can store all that mess, but I can't fit it in through the cmdlet to create the object. Lovely. Any ideas?

Lots of dropped packages when tcpdumping on busy interface

- by Frands Hansen

My challenge I need to do tcpdumping of a lot of data - actually from 2 interfaces left in promiscuous mode that are able to see a lot of traffic. To sum it up Log all traffic in promiscuous mode from 2 interfaces Those interfaces are not assigned an IP address pcap files must be rotated per ~1G When 10 TB of files are stored, start truncating the oldest What I currently do Right now I use tcpdump like this: tcpdump -n -C 1000 -z /data/compress.sh -i any -w /data/livedump/capture.pcap $FILTER The $FILTER contains src/dst filters so that I can use -i any. The reason for this is, that I have two interfaces and I would like to run the dump in a single thread rather than two. compress.sh takes care of assigning tar to another CPU core, compress the data, give it a reasonable filename and move it to an archive location. I cannot specify two interfaces, thus I have chosen to use filters and dump from any interface. Right now, I do not do any housekeeping, but I plan on monitoring disk and when I have 100G left I will start wiping the oldest files - this should be fine. And now; my problem I see dropped packets. This is from a dump that has been running for a few hours and collected roughly 250 gigs of pcap files: 430083369 packets captured 430115470 packets received by filter 32057 packets dropped by kernel <-- This is my concern How can I avoid so many packets being dropped? These things I did already try or look at Changed the value of /proc/sys/net/core/rmem_max and /proc/sys/net/core/rmem_default which did indeed help - actually it took care of just around half of the dropped packets. I have also looked at gulp - the problem with gulp is, that it does not support multiple interfaces in one process and it gets angry if the interface does not have an IP address. Unfortunately, that is a deal breaker in my case. Next problem is, that when the traffic flows though a pipe, I cannot get the automatic rotation going. Getting one huge 10 TB file is not very efficient and I don't have a machine with 10TB+ RAM that I can run wireshark on, so that's out. Do you have any suggestions? Maybe even a better way of doing my traffic dump altogether.

20GB+ worth of emails in my /home what is a better solution for that?

- by Skinkie

My email storage requirements are outgrowing anything reasonable with respect to local mail storage. As we speak 99% of my home partition is filled with personal mail in Thunderbirds mail dirs. Needless to say, this is just painful, badly searchable and as history has proven me that backups work, but Thunderbird is capable of loosing a lot of mail very easily. Currently I have an remote IMAPS server (Dovecot) running for my daily mail, accessible from anywhere, which from my own practice works efficiently up to about 1000 emails. Then some archive directories should be used to move mail around. I have been looking into DBMail, but I wonder if I make my case worse or better which such solution. None of the supported database employ string deduplication or string compression out of the box, so is this going to help me with 20GB+ mail? What about falling back to a plain old IMAP server? A filesystem like ZFS would support stuff like GZIP transparently, which could help. Could someone share their thoughts? The 20GB mostly consists of mailinglists, and normal mail. Not things like attachments. To add some clarifications; As we speak, my mail is not server side indexed at all - only my new mail arrives at a remote IMAP server. It is all local storage from former POP3 accounts, local mirrored Gmail and IMAP accounts. In my perspective it is not Thunderbird that sucks, its fileformat that sucks. Regarding the 1000 mails. On the road I am using Alpine and MobileMail, quite happy with both of them, but some management is required to actually manage the mail. Sieve helps a lot with that, but browing through 10.000 e-mails is not fun, especially not on a mobile client. I am quite happy with Dovecot, never had any issues with it. I just wonder if this is the way to go. Or if there are any other better solutions. What my question is: what is the best practice solution that allows 20GB+ mails and is -on demand remotely accessible, easy to backup and archive worthy. It doesn't need to be available 24x7. The final approach I took was installing a local IMAP server (Dovecot), configured it for being my archive, using the following guide: http://en.gentoo-wiki.com/wiki/Dovecot/InstallThunderbird

Why does Excel now give me already existing name range error on Copy Sheet?

- by WilliamKF

I've been working on a Microsoft Excel 2007 spreadsheet for several days. I'm working from a master template like sheet and copying it to a new sheet repeatedly. Up until today, this was happening with no issues. However, in the middle of today this suddenly changed and I do not know why. Now, whenever I try to copy a worksheet I get about ten dialogs, each one with a different name range object (shown below as 'XXXX') and I click yes for each one: A formula or sheet you want to move or copy contains the name 'XXXX', which already exists on the destination worksheet. Do you want to use this version of the name? To use the name as defined in destination sheet, click Yes. To rename the range referred to in the formula or worksheet, click No, and enter a new name in the Name Conflict dialog box. The name range objects refer to cells in the sheet. For example, E6 is called name range PRE on multiple sheets (and has been all along) and some of the formulas refer to PRE instead of $E$6. One of the 'XXXX' above is this PRE. These name ranges should only be resolved within the sheet within which they appear. This was not an issue before despite the same name range existing on multiple sheets before. I want to keep my name ranges. What could have changed in my spreadsheet to cause this change in behavior? I've gone back to prior sheets created this way and now they give the message too when copied. I tried a different computer and a different user and the same behavior is seen everywhere. I can only conclude something in the spreadsheet has changed. What could this be and how can I get back the old behavior whereby I can copy sheets with name ranges and not get any errors? Looking in the Name Manager I see that the name ranges being complained about show twice, once as scope Template and again as scope Workbook. If I delete the scope Template ones the error goes away on copy however, I get a bunch of #REF errors. If I delete the scope Workbook ones, all seems okay and the errors on copy go away too, so perhaps this is the answer, but I'm nervous about what effect this deletion will have and wonder how the Workbook ones came into existence in the first place. Will it be safe to just delete the Workbook name manager scoped entries and how might these have come into existence without my knowing it to begin with?

How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment

- by user69508

(Please forgive if this is posted in an incorrect forum. We didn’t know exactly where to post it.) We have an ASP.NET Web API single page application - a browser-based app running in IIS to serve up HTML5/CSS3/JavaScript, which talks to the ASP.NET Web API endpoint only to access a database and transfer JSON data. Everything is working great in our development environment - that is, we have one Visual Studio solution with an ASP.NET Web API project and two class library projects for data access. While development and testing on development boxes, using IIS Express to a localhost:port to run the site and access the Web API, everything is fine. Now we need to move it to a production environment (and we’re having problems - or just not understanding what needs to be done). The production environment is all internal (nothing will be exposed on the public Internet). There are two domains. One domain, the corporate domain, is where all users login normally. The other domain, the process domain, contains the SQL Server instance that our app and Web API will need to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. So, I guess what they want is: corp domain (end users) <– firewall (open port 80) <– DMZ (web server running IIS) <– firewall (open port 80 or 1433????) <– process domain (IIS for Web API and SQL Server) We’re developers and don’t really understand all the networking aspects, so we’re wondering how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code (HTML5/CSS3/JavaScript/images/etc.) is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Or, does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to "http://server/appname/api/getitmes"? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? I’m sure there are other questions, but we’ll start with these. Thanks!!! (Note: the servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.)

IE9 Error: There was a pr?blem sending the command to the program

- by HK1

I'm working on a new/fresh Windows 7 32bit machine that now has IE9 installed. The user is using the Dell Stardock application as his primary "desktop" (all his links there). When we place an internet link there and click on it we get the following error message: There was a problem sending the command to the program. To me this indicates that IE9 is having trouble going to the website we want to go to, which should get passed as a parameter to the browser when it opens. I don't think this is a StarDock/ObjectDock problem because we also have some other problems with internet links. For example, we cannot move an internet link from the Desktop to the Quick Launch on the task bar. When we do try, it forces us to put the link with the IE icon as part of the IE menu instead of allowing us to have a shortcut there as it's own entry. I should mention however, that links on the desktop and in the taskbar do work as we expect them too (without showing the above error message). It appears that this problem started after installing Windows Updates. Since we installed a whole bunch of updates at once I have no idea which one caused the problem. I did have Google Chrome installed but I uninstalled it since the user wants to use IE. The problem started before I uninstalled Chrome. I also reset the browser settings on IE9. It didn't help. Next I uninstalled IE9 which took me back to IE8. This actually did resolve the problem but the problem came back as soon as I installed IE9 again. We have Verizon Internet Security installed. It's actually a McAfee product rebranded to look like Verizon. I'm not real crazy over this software but the customer has a subscription so we're not planning to change it. I have no reason to believe that this is causing the problem and yet I know that security software is often to blame for strange issues. I've looked at the registry settings for the following keys and everything appears to be ok for every single one of them: HKEY_CLASSES_ROOT\.htm HKEY_CLASSES_ROOT\.html HKEY_CLASSES_ROOT\http\shell\open\command HKEY_CLASSES_ROOT\http\shell\open\ddeexec\Application HKEY_CLASSES_ROOT\https\shell\open\command HKEY_CLASSES_ROOT\https\shell\open\ddeexec\Application HKEY_CLASSES_ROOT\htmlfile\shell\open\command HKEY_CLASSES_ROOT\Microsoft.Website\Shell\Open\Command Edit1: I've found two potential solutions but I won't be able to try them until tomorrow. One is to disable the "Windows Font Cache" service. Another is to clear IE cache and browsing history. I won't be able to try out either solution until tomorrow since this is a remote client's machine. I see there are lots of other suggestions online but if you take the time to read them through you'll see that the other suggestions didn't fix the problem.

Cloud storage provider lost my data. How to back up next time?

- by tomcam

What do you do when cloud storage fails you? First, some background. A popular cloud storage provider (rhymes with Booger Link) damaged a bunch of my data. Getting it back was an uphill battle with all the usual accusations that it was my fault, etc. Finally I got the data back. Yes, I can back this up with evidence. Idiotically, I stayed with them, so I totally get that the rest of this is on me. The problem had been with a shared folder that works with all 12 computers my business and family use with the service. We'll call that folder the Tragic Briefcase. It is a sort of global folder that's publicly visible to all computers on the service. It's our main repository. Today I decided to deal with some residual effects of the Crash of '11. Part of the damage they did was that in just one of my computers (my primary, of course) all the documents in the Tragic Briefcase were duplicated in the Windows My Documents folder. I finally started deleting them. But guess what. Though they appeared to be duplicated in the file system, removing them from My Documents on the primary PC caused them to disappear from the Tragic Briefcase too. They efficiently disappeared from all the other computers' Tragic Briefcases as well. So now, 21 gigs of files are gone, and of course I don't know which ones. I want to avoid this in the future. Apart from using a different storage provider, the bigger picture is this: how do I back up my cloud data? A complete backup every week or so from web to local storage would cause me to exceed my ISP's bandwidth. Do I need to back up each of my 12 PCs locally? I do use Backupify for my primary Google Docs, but I have been storing taxes, confidential documents, Photoshop source, video source files, and so on using the web service. So it's a lot of data, but I need to keep it safe. Backup locally would also mean 2 backup drives or some kind of RAID per PC, right, because you can't trust a single point of failure? Assuming I move to DropBox or something of its ilk, what is the best way to make sure that if the next cloud storage provider messes up I can restore?

Can't recover hard drive

- by BreezyChick89

My drive got corrupt after a thunderstorm. It used to be 1 partition of 2.5tb but now it shows 2 partitions. It's weird because 300gig free space is about how much it had before corrupting, but it was part of the first partition. I tried $ sudo resize2fs -f /dev/sdb1 Resizing the filesystem on /dev/sdb1 to 536870911 (4k) blocks. resize2fs: Can't read an block bitmap while trying to resize /dev/sdb1 Please run 'e2fsck -fy /dev/sdb1' to fix the filesystem after the aborted resize operation. sudo e2fsck -f /dev/sdb1 e2fsck 1.42 (29-Nov-2011) The filesystem size (according to the superblock) is 610471680 blocks The physical size of the device is 536870911 blocks Either the superblock or the partition table is likely to be corrupt! Abort? n .... Error reading block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes Force rewrite<y>? yes Error writing block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes ... A lot of these. I can't use e2fsck -y because the first question aborts if I say "y". If I put a weight on the 'y' key it fails because none of the errors were really fixed. I asked this question before and tried using gparted but gparted fails because the first thing it does is: e2fsck -f -y -v /dev/sdb1 giving the same error. The disk status says healthy. There are no bad blocks. This is very frustrating because I can see the data in testdisk and it looks like it's all there. I already bought another 2.5tb drive and made a clone using dd. The next step if I can't fix this is to wipe that drive and just move the data with testdisk, but it seems certain folders will copy infinitely until the drive is full because of symlinks or errors so it's also a difficult option. sudo fdisk -l Disk /dev/sdb: 2500.5 GB, 2500495958016 bytes 255 heads, 63 sectors/track, 304001 cylinders, total 4883781168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0005da5e Device Boot Start End Blocks Id System /dev/sdb1 * 2048 4294969342 2147483647+ 83 Linux sudo badblocks -b 4096 -n -o badfile /dev/sdb 610471680 536870911 badfile is empty I also tried changing the superblock with "fsck -b" but all of them are the same.

Code Contracts with Interfaces: "Method Invocation skipped. Compiler will generate method invocation

- by Jörg Battermann

Good evening, I just started playing with Microsoft.Contracts (latest version) and plugging it on top of a sample interface and right now it looks like this: namespace iRMA2.Core.Interfaces { using System; using System.Collections.Generic; using System.ComponentModel.Composition; using System.Diagnostics.Contracts; /// <summary> /// Base Interface declarations for iRMA2 Extensions /// </summary> [InheritedExport] [ContractClass(typeof(IiRMA2ExtensionContract))] public interface IiRMA2Extension { /// <summary> /// Gets the name. /// </summary> /// <value>The name of the Extension.</value> string Name { get; } /// <summary> /// Gets the description. /// </summary> /// <value>The description.</value> string Description { get; } /// <summary> /// Gets the author of the extension.

'blured' out visually with the tooltip saying "Method Invocation skipped. Compiler will generate method invocation because the method is conditional or it is partial method without implementation" and in fact the CodeContracts output does not count/show them... What am I missing & doing wrong here? -J

Where is ScriptManager.IsStartupScriptRegistered method?

- by Ismail S

Below is my code if (!Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey)) { ScriptManager scriptManager = ScriptManager.GetCurrent(page); if (scriptManager != null && scriptManager.IsInAsyncPostBack) { //if a MS AJAX request, use the Scriptmanager class ScriptManager.RegisterStartupScript(Page, Page.GetType(), scriptKey, script, true); } else { //if a standard postback, use the standard ClientScript method Page.ClientScript.RegisterStartupScript(Page.GetType(), scriptKey, script, true); } } I'm doing as suggested in this answer so that I can register startup script on both times i.e. when there is partial postback and a full postback. The problem is Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey) always returns false when it is partial postback. And I couldn't find ScriptManager.IsStartupScriptRegistered method. As a result of this additional script is emitted on all partial/async postbacks. Please note that I'm using script manager of AjaxControlToolkit version 4.1 i.e. ToolkitScriptManager in my masterpage. But I don't thing it has something to do with this.

List getting cleared every button click inside Update Panel?

- by sah302

No this isn't a copy of this question: http://stackoverflow.com/questions/654423/button-in-update-panel-is-doing-a-full-postback I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Markup: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList>  <asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again. I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked. I know this is something simple, but all the combinations I've tried won't get it to work. How can I make this thing work? Edited: It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback. The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associatedFaculty list is getting reset each time I click the button?

How to refresh DataGrid and DropDown on main page after hiding modal popup

- by James

Hi, I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed even though I have Rebound the controls. I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail... It seems I need to cause a postback but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.

Design pattern for cost calculator app?

- by Anders Svensson

Hi, I have a problem that I’ve tried to get help for before, but I wasn’t able to solve it then, so I’m trying to simplify the problem now to see if I can get some more concrete help with this because it is driving me crazy… Basically, I have a working (more complex) version of this application, which is a project cost calculator. But because I am at the same time trying to learn to design my applications better, I would like some input on how I could improve this design. Basically the main thing I want is input on the conditionals that (here) appear repeated in two places. The suggestions I got before was to use the strategy pattern or factory pattern. I also know about the Martin Fowler book with the suggestion to Refactor conditional with polymorphism. I understand that principle in his simpler example. But how can I do either of these things here (if any would be suitable)? The way I see it, the calculation is dependent on a couple of conditions: 1. What kind of service is it, writing or analysis? 2. Is the project small, medium or large? (Please note that there may be other parameters as well, equally different, such as “are the products new or previously existing?” So such parameters should be possible to add, but I tried to keep the example simple with only two parameters to be able to get concrete help) So refactoring with polymorphism would imply creating a number of subclasses, which I already have for the first condition (type of service), and should I really create more subclasses for the second condition as well (size)? What would that become, AnalysisSmall, AnalysisMedium, AnalysisLarge, WritingSmall, etc…??? No, I know that’s not good, I just don’t see how to work with that pattern anyway else? I see the same problem basically for the suggestions of using the strategy pattern (and the factory pattern as I see it would just be a helper to achieve the polymorphism above). So please, if anyone has concrete suggestions as to how to design these classes the best way I would be really grateful! Please also consider whether I have chosen the objects correctly too, or if they need to be redesigned. (Responses like "you should consider the factory pattern" will obviously not be helpful... I've already been down that road and I'm stumped at precisely how in this case) Regards, Anders The code (very simplified, don’t mind the fact that I’m using strings instead of enums, not using a config file for data etc, that will be done as necessary in the real application once I get the hang of these design problems): public abstract class Service { protected Dictionary<string, int> _hours; protected const int SMALL = 2; protected const int MEDIUM = 8; public int NumberOfProducts { get; set; } public abstract int GetHours(); } public class Writing : Service { public Writing(int numberOfProducts) { NumberOfProducts = numberOfProducts; _hours = new Dictionary<string, int> { { "small", 125 }, { "medium", 100 }, { "large", 60 } }; } public override int GetHours() { if (NumberOfProducts <= SMALL) return _hours["small"] * NumberOfProducts; if (NumberOfProducts <= MEDIUM) return (_hours["small"] * SMALL) + (_hours["medium"] * (NumberOfProducts - SMALL)); return (_hours["small"] * SMALL) + (_hours["medium"] * (MEDIUM - SMALL)) + (_hours["large"] * (NumberOfProducts - MEDIUM)); } } public class Analysis : Service { public Analysis(int numberOfProducts) { NumberOfProducts = numberOfProducts; _hours = new Dictionary<string, int> { { "small", 56 }, { "medium", 104 }, { "large", 200 } }; } public override int GetHours() { if (NumberOfProducts <= SMALL) return _hours["small"]; if (NumberOfProducts <= MEDIUM) return _hours["medium"]; return _hours["large"]; } } public partial class Form1 : Form { public Form1() { InitializeComponent(); List<int> quantities = new List<int>(); for (int i = 0; i < 100; i++) { quantities.Add(i); } comboBoxNumberOfProducts.DataSource = quantities; } private void comboBoxNumberOfProducts_SelectedIndexChanged(object sender, EventArgs e) { Service writing = new Writing((int) comboBoxNumberOfProducts.SelectedItem); Service analysis = new Analysis((int) comboBoxNumberOfProducts.SelectedItem); labelWriterHours.Text = writing.GetHours().ToString(); labelAnalysisHours.Text = analysis.GetHours().ToString(); } }

iphone - UIViewController header view errors

- by Fiona

Hi there, So to give a little background: I've an app that has a UITableViewController- (ContactDetailViewController) In this view at the top, I require a few labels and buttons, followed by a group style tableview. So I've created a nib file containing these elements. (ContactHeaderView.xib) Then in the viewDidLoad of ContactDetailViewController I've loaded this nib as the headerView. See implementation file below: #import "ContactDetailViewController.h" #import "DisplayInfoViewController.h" #import "ActionViewController.h" @implementation ContactDetailViewController @synthesize name; @synthesize date; @synthesize nextAction; @synthesize nameLabel; @synthesize usernameLabel; @synthesize nextActionTextField; @synthesize dateLabel; @synthesize contactInfoButton; @synthesize backgroundInfoButton; @synthesize actionDoneButton; - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

Button in Update Panel doing full postback?

- by sah302

No this isn't a copy of this question: http://stackoverflow.com/questions/654423/button-in-update-panel-is-doing-a-full-postback I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Markup: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList>  <asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again. I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked. I know this is something simple, but all the combinations I've tried won't get it to work. How can I make this thing work?

IE 8 Automatically Closing <header> tag

- by djthoms

Background I am currently working on the final QA of a responsive website and I'm having an issue with IE 8 and IE 7. My client deals with government contracting so their website needs to be compatible with IE 8 and IE 7. I am using Modernizr with html5shiv built in. I am loading Modernizr in the footer of a WordPress theme that was custom built for this project. I'm not missing a doctype or any other obvious code. I am using the following scripts, all of which are loaded in the footer of WordPress: jQuery 1.10.1 Modernizr 2.6.3 (click for config) respond.js 1.3.0 superfish jQuery Waypoints 2.0.3 jQuery Waypoints Sticky 2.0.3 The Situation I'm having an issue with IE 8 automatically closing a <header> tag. First, I have used two utilities to check this issue: IETester IE 11 emulated to IE 8 w/ IE 8 User agent Here is the correct output <div class="wrapper main-header"> <header class="container"> <div class="sixteen columns alpha omega"> <div class="eight columns alpha omega logo"> <a href="http://example.com"><img src="http://example.com/wp-content/uploads/2013/10/logo.png" alt="Example"></a> </div> <div class="wrapper main-navigation desktop"> <nav id="nav" class="six columns alpha omega"> ... </nav> <div class="eight columns alpha omega overlay" style="display: none;"> ... </div> <div class="two columns alpha omega menu-ss"> ... </div> </div> </div> </header> </div> What IE 8 is rendering: <div class="wrapper main-header"> <header class="container"></header> <div class="sixteen columns alpha omega"> <div class="eight columns alpha omega logo"> <a href="http://example.com"><img src="http://example.com/wp-content/uploads/2013/10/logo.png" alt="Example"></a> </div> <div class="wrapper main-navigation desktop"> <nav id="nav" class="six columns alpha omega"> ... </nav> <div class="eight columns alpha omega overlay" style="display: none;"> ... </div> <div class="two columns alpha omega menu-ss"> ... </div> </div> </div> </header><//header> </div> What I have Tried Loading html5shiv with IE conditional in the <head> Loading Modernizr in the <head> I have looked at these Stackoverflow questions/answers: html 5 tags foorter or header in ie 8 and ie 7 html5 not rendering header tags in ie IE 8 self closing tags automatically Any assistance with this is greatly appreciated! I would really really really like to finish this website over the weekend. I've been banging my head against a wall for the past few hours over this issue.

How to retrieve ID of button clicked within usercontrol on Asp.net page?

- by Shawn Gilligan

I have a page that I am working on that I'm linking multiple user controls to. The user control contains 3 buttons, an attach, clear and view button. When a user clicks on any control on the page, the resulting information is "dumped" into the last visible control on the page. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" MasterPageFile="DefaultPage.master" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> <%@ Register tagName="FileHandler" src="FileHandling.ascx" tagPrefix="ucFile" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server"> <asp:UpdatePanel ID="upPanel" UpdateMode="Conditional" runat="server"> <ContentTemplate> <table> <tr> <td> <ucFile:FileHandler ID="fFile1" runat="server" /> </td> <td> <ucFile:FileHandler ID="fFile2" runat="server" /> </td> </tr> </table> </ContentTemplate> </asp:UpdatePanel> </asp:Content> All file handling and processing is handled within the control, with an event when the upload to the file server is complete via a file name that was generated. When either button is clicked, the file name is always stored internal to the control in the last control's text box. Control code: <table style="width: 50%;"> <tr style="white-space: nowrap;"> <td style="width: 1%;"> <asp:Label runat="server" ID="lblFile" /> </td> <td style="width: 20%;"> <asp:TextBox ID="txtFile" CssClass="backColor" runat="server" OnTextChanged="FileInformationChanged" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnUpload" CssClass="btn" Text="Attach" OnClick="UploadFile"/>--%> <input type="button" id="btnUpload" class="btn" tabindex="30" value="Attach" onclick="SetupUpload();" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnClear" Text="Clear" CssClass="btn" OnClick="ClearTextValue"/>--%> <input type="button" id="btnClearFile" class="btn" value="Clear" onclick="document.getElementById('<%=txtFile.ClientID%>').value = '';document.getElementById('<%=hfFile.ClientID%>').value = '';" /> </td> <td style="width: 1%"> <a href="#here" onclick="ViewLink(document.getElementById('<%=hfFile.ClientID%>').value, '')">View</a> </td> <td style="width: 1%"> <asp:HiddenField ID="hfFile" runat="server" /> </td> </tr> </table> <script type="text/javascript"> var ItemPath = ""; function SetupUpload(File) { ItemPath = File; VersionAttach('<%=UploadPath%>', 'true'); } function UploadComplete(File) { document.getElementById('<%=txtFile.ClientID%>').value = File.substring(File.lastIndexOf("/") + 1); document.getElementById('<%=hfFile.ClientID%>').value = File; alert('<%=txtFile.Text %>'); alert('<%=ClientID %>') } function ViewLink(File, Alert) { if (File != "") { if (File.indexOf("../data/") != -1) { window.open(File, '_blank'); } else { window.open('../data/<%=UploadPath%>/' + File, '_blank'); } } else if (Alert == "") { alert('No file has been uploaded for this field.'); } } </script>

How to Create Auto Playlists in Windows Media Player 12

- by DigitalGeekery

Are you getting tired of the same old playlists in Windows Media Player? Today we’ll show you how to create dynamic auto playlists based on criteria you choose in WMP 12 in Windows 7. Auto Playlists In Library view, click on Create playlist dropdown arrow and select Create auto playlist. On the New Auto Playlist window type in a name for the playlist in the text box. Now we need to choose our criteria by which to filter your playlist. Select Click here to add criteria. For our example, we will create a playlist of songs that were added to the library in the last week from the Alternative genre. So, we will first select Date Added from the dropdown list. Many criteria will have addition options to configure. In the example below you will see that we have a few options to fine tune. We will filter all the songs added to the library in the last 7 days. We will select Is After from the first dropdown list. Then select Last 7 Days from the second dropdown list. You can add multiple criteria to further filter your playlist. If you can’t find the criteria you are looking for, select “More” at the bottom of the dropdown list. This will pull up a filter window with all the criteria. Select a filter and then click OK when finished. From the Genre dropdown, we will select Alternative. If you’d like to add Pictures, Videos, or TV Shows to your auto playlists you can do so by selecting them from the dropdown list under And also include. You will then be able to select criteria for your pictures, videos, or TV shows from the dropdown list. Finally, you can also add restrictions to your music such as the number of items, duration, or total size. We will limit the duration of our playlist to one hour by selecting Limit Total Duration To… Then type in 1 hour…Click OK. Our library is automatically filtered and a playlist is created based on the criteria we selected. When additional songs are added to the Windows Media Player library, any of new songs that fit the criteria will automatically be added to the New Songs playlist. You can also save a copy of an auto playlist as a regular playlist. Switch to Playlists view by clicking Playlists from either the top menu or the navigation bar. Select the Play tab and then click Clear list to remove any tracks from the list pane. Right-click on the playlist you want to save, select Add to, and then Play list. The songs from your auto playlist will appear as an Unsaved list on the list pane. Click Save list. Type in a name for your playlist. Your auto playlist will continue to change as you add or remove items from your Media Player library that meet the criteria you established. The new saved playlist we just created will stay as it is currently. Editing a Auto playlist is easy. Right-click on the playlist and select Edit. Now you are ready to enjoy your playlist. Conclusion Auto playlists are great way to keep your playlists fresh in Windows Media Player 12. Users can get creative and experiment with the wide variety of criteria to customize their listening experience.

Is this right in the use case of exec method of child_process? is there away to cody the envirorment along with the require module too?

- by L2L2L

I'm learning node. I am using child_process to move data to another script to be executed. But it seem that it does not copy the hold environment or I could be doing something wrong. To copy the hold environment --require modules too-- or is this when I use spawn, I'm not so clear or understanding spawn exec and execfile --although execfile is like what I'm doing at the bottom, but with exec... right?-- And I would just love to have some clarity on this matter. Please anyone? Thank you. parent.js - "use strict"; var fs, path, _err; fs = require("fs"), path = require("path"), _err = require("./err.js"); var url; url= process.argv[1]; var dirname, locate_r; dirname = path.dirname(url); locate_r = dirname + "/" + "test.json";//path.join(dirname,"/", "test.json"); var flag, str; flag = "r", str = ""; fs.open(locate_r, flag, function opd(error, fd){ if (error){_err(error, function(){ fs.close(fd,function(){ process.stderr.write("\n" + "In Finally Block: File Closed!" + "\n");});})} var readBuff, buffOffset, buffLength, filePos; readBuff = new Buffer(15), buffOffset = 0, buffLength = readBuff.length, filePos = 0; fs.read(fd, readBuff, buffOffset, buffLength, filePos, function rd(error, readBytes){ error&&_err(error, fd); str = readBuff.toString("utf8"); process.env.str = str; process.stdout.write("str: "+ str + "\n" + "readBuff: " + readBuff + "\n"); fs.close(fd, function(){process.stdout.write( "Read and Closed File." + "\n" )}); //write(str); //run test for process.exec** var env, varName, envCopy, exec; env = process.env, varName, envCopy = {}, exec = require("child_process").exec; for(varName in env){ envCopy[varName] = env[varName]; } process.env.fs = fs, process.env.path = path, process.env.dirname = dirname, process.env.flag = flag, process.env.str = str, process.env._err = _err; process.env.fd = fd; exec("node child.js", env, function(error, stdout, stderr){ if(error){throw (new Error(error));} }); }); }); child.js - "use strict"; var fs, path, _err; fs = require("fs"), path = require("path"), _err = require("./err.js"); var fd, fs, flag, path, dirname, str, _err; fd = process.env.fd, //fs = process.env.fs, //path = process.env.path, dirname = process.env.dirname, flag = process.env.flag, str = process.env.str, _err = process.env._err; var url; url= process.argv[1]; var locate_r; dirname = path.dirname(url); locate_r = dirname + "/" + "test.json";//path.join(dirname,"/", "test.json"); //function write(str){ var locate_a; locate_a = dirname + "/" + "test.json"; //path.join(dirname,"/", "test.json"); flag = "a"; fs.open(locate_a, flag, function opd(error, fd){ error&&_err(error, fs, fd); var writeBuff, buffPos, buffLgh, filePs; writeBuff = new Buffer(str), process.stdout.write( "writeBuff: " + writeBuff + "\n" + "str: " + str + "\n"), buffPos = 0, buffLgh = writeBuff.length, filePs = buffLgh;//null; fs.write(fd, writeBuff, buffPos, buffLgh, filePs-3, function(error, written){ error&&_err(error, function(){ fs.close(fd,function(){ process.stderr.write("\n" + "In Finally Block: File Closed!" + "\n"); }); }); fs.close(fd, function(){process.stdout.write( "Written and Closed File." + "\n");}); }); }); //} err.js - "use strict"; var fs; fs = require("fs"); module.exports = function _err(err, scp, cd){ try{ throw (new Error(err)); }catch(e){ process.stderr.write(e + "\n"); }finally{ cd; } }

Our Look at the Internet Explorer 9 Platform Preview

- by Asian Angel

Have you been hearing all about Microsoft’s work on Internet Explorer 9 and are curious about it? If you are wanting a taste of the upcoming release then join us as we take a look at the Internet Explorer 9 Platform Preview. Note: Windows Vista and Server 2008 users may need to install a Platform Update (see link at bottom for more information). Getting Started If you are curious about the systems that the platform preview will operate on here is an excerpt from the FAQ page (link provided below). There are two important points of interest here: The platform preview does not replace your regular Internet Explorer installation The platform preview (and the final version of Internet Explorer 9) will not work on Windows XP There really is not a lot to the install process…basically all that you will have to deal with is the “EULA Window” and the “Install Finished Window”. Note: The platform preview will install to a “Program Files Folder” named “Internet Explorer Platform Preview”. Internet Explorer 9 Platform Preview in Action When you start the platform preview up for the first time you will be presented with the Internet Explorer 9 Test Drive homepage. Do not be surprised that there is not a lot to the UI at this time…but you can get a good idea of how Internet Explorer will act. Note: You will not be able to alter the “Homepage” for the platform preview. Of the four menus available there are two that will be of interest to most people…the “Page & Debug Menus”. If you go to navigate to a new webpage you will need to go through the “Page Menu” unless you have installed the Address Bar Mini-Tool (shown below). Want to see what a webpage will look like in an older version of Internet Explorer? Then choose your version in the “Debug Menu”. We did find it humorous that IE6 was excluded from the choices offered. Here is what the URL entry window looks like if you are using the “Page Menu” to navigate between websites. Here is the main page of the site here displayed in “IE9 Mode”…looking good. Here is the main page viewed in “Forced IE5 Document Mode”. There were some minor differences (colors, sidebar, etc.) in how the main page displayed in comparison to “IE9 Mode”. Being able to switch between modes makes for an interesting experience… As you can see there is not much to the “Context Menu” at the moment. Notice the slightly altered icon for the platform preview… “Add” an Address Bar of Sorts If you would like to use a “make-shift” Address Bar with the platform preview you can set up the portable file (IE9browser.exe) for the Internet Explorer 9 Test Platform Addressbar Mini-Tool. Just place it in an appropriate folder, create a shortcut for it, and it will be ready to go. Here is a close look at the left side of the Address Bar Mini-Tool. You can try to access “IE Favorites” but may have sporadic results like those we experienced during our tests. Note: The Address Bar Mini-Tool will not line up perfectly with the platform preview but still makes a nice addition. And a close look at the right side of the Address Bar Mini-Tool. In order to completely shut down the Address Bar Mini-Tool you will need to click on “Close”. Each time that you enter an address into the Address Bar Mini-Tool it will open a new window/instance of the platform preview. Note: During our tests we noticed that clicking on “Home” in the “Page Menu” opened the previously viewed website but once we closed and restarted the platform preview the test drive website was the starting/home page again. Even if the platform preview is not running the Address Bar Mini-Tool can still run as shown here. Note: You will not be able to move the Address Bar Mini-Tool from its’ locked-in position at the top of the screen. Now for some fun. With just the Address Bar Mini-Tool open you can enter an address and cause the platform preview to open. Here is our example from above now open in the platform preview…good to go. Conclusion During our tests we did experience the occasional crash but overall we were pleased with the platform preview’s performance. The platform preview handled rather well and definitely seemed much quicker than Internet Explorer 8 on our test system (a definite bonus!). If you are an early adopter then this could certainly get you in the mood for the upcoming beta releases!
