• Visual Studio 2010 Beta 2, built-in font smoothing

  - by L. Shaydariv

  I've just installed Visual Studio 2010 Beta 2 onto my Windows XP to evaluate it and check whether it meets my preferences the way it did before. Okay, I've temporary defeated an urgent bug with a strange workaround (I could not open any file from the Solution Explorer), and it left bad memories to me. But however, it's okay. The first thing I've seen just opening the code editor was ClearType font rendering. Wow, so unexpectedly. I must note that I do not use standard Windows rendering techniques, but I still prefer GDI++, a font renderer developed by Japanese developers. (GDI++ allows to render the fonts in Mac/Win-Safari style over entire Windows.) Personally for me, GDI++ reaches the great font-rendering results allowing me to use the Dejavu Sans Mono font with really nice smoothing in Visual Studio 2008 (VS 2005 too, though VS 2005 crashes in this case). But GDI++ cannot affect Visual Studio 2010 Beta 2 text editor - it uses ClearType (right?), and it does not care about the system font smoothing settings. It could be an editor based on WPF, right? So as far as I can see, I can't use GDI++ anymore because it uses Windows GDI(+) but no WPF? So I've got several questions: Is it possible to disable VS 2010 b2 built-in ClearType or override it with another font smoother? Is it possible to install a Safari-like font renderer for Visual Studio 2010 [betas]? Thanks a lot.

• Nginx + PHP-FPM Timeouts, almost zero load consumption?

  - by javipas

  I've got a server running on a Linode with Ubuntu 10.04 LTS, Nginx 0.7.65, MySQL 5.1.41 and PHP 5.3.2 with PHP-FPM. There is a WordPress blog on it, updated to WordPress 3.2.1 recently. I have made no changes to the server (except updating WordPress) and while it was running fine, a couple of days ago I started having downtimes. I tried to solve the problem, and checking the error_log I saw many timeouts and messages that seemed to be related to timeouts. The server is currently logging this kind of errors: 2011/07/14 10:37:35 [warn] 2539#0: *104 an upstream response is buffered to a temporary file /var/lib/nginx/fastcgi/2/00/0000000002 while reading upstream, client: 217.12.16.51, server: www.mydomain.com, request: "GET /page/2/ HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "www.mydomain.com", referrer: "http://www.mydomain.com/" 2011/07/14 10:40:24 [error] 2539#0: *231 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 46.24.245.181, server: www.mydomain.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.mydomain.com", referrer: "http://www.google.es/search?sourceid=chrome&ie=UTF-8&q=mydomain" and even saw this previous serverfault discussion with a possible solution: to edit /etc/php/etc/php-fpm.conf and change request_terminate_timeout=30s instead of ;request_terminate_timeout= 0 The server worked for some hours, and then broke again. I edited the file again to leave it as it was, and restarted again php-fpm (service php-fpm restart) but no luck: the server worked for a few minutes and back to the problem over and over. The strange thing is, although the services are running, htop shows there is no CPU load (see image) and I really don't know how to solve the problem. The config files are on pastebin The php-fpm.conf file is here The /etc/nginx/nginx.conf is here The /etc/nginx/sites-available/www.mydomain.com is here Please help :(

• DNS issue on Fedora 12? wget wordpress.org fails where wget www.google.com works

• HD video editing system with Truecrypt

  - by Rob

  I'm looking to do hi-def video editing and transcoding on an unencrypted standard partition, with Truecrypt on the system partition for sensitive data. I'm aiming to keep certain data private but still have performance where needed. Goals: Maximum, unimpacted, performance possible for hi-def video editing, encryption of video not required Encrypt system partition, using Truecrypt, for web/email privacy, etc. in the event of loss In other words I want to selectively encrypt the hard drive - i.e. make the system partition encrypted but not impact the original maximum performance that would be available to me for hi-def/HD video editing. The thinking is to use an unencrypted partition for the video and set up video applications to point at that. Assuming that they would use that partition only for their workspace and not the encrypted system partition, then I should expect to not get any performance hit. Would I be correct? I guess it might depend on the application, if that app is hard-wired to use the system partition always for temporary storage during editing and transcoding, or if it has to be installed on the C: system partition always. So some real data on how various apps behave in the respect would be useful, e.g. Adobe, Cyberlink, Nero etc. etc. I have a Intel i7 Quad-core (8 threads) 1.6Ghz (up to 2.8Ghz turbo-boost) 4Gb, 7200rpm SATA, nvidia HP laptop. I've read the excellent posting about the general performance impact of truecrypt but the benchmarks weren't specific enough for my needs where I'm dealing with HD-video and using a non-encrypted partition to maintain max performance.

• Cannot remove storage account because of lease, but I already deleted the server [closed]

  - by djechelon

  I recently created a temporary virtual server on Azure. Then I deleted it. I wanted to delete the storage account associated with it because I didn't need it any more. The problem is that the VHD file is still associated to a non-existing virtual machine!! If I try to delete the VHD from Virtual Machines\Disks I get the Delete button greyed and the table tells me it's still associated with the old VM. If I go to storage administration and try to delete the blob from vhds/ directory I get there is an active lease. I've read on Azure forums that, in these case, one should try to force releasing the lease from the blob. I followed their instructions and downloaded their script, but running it failed. The script detected that the disk is associated to a Virtual Machine and can't be deleted. The problem is that I'm 1000000% sure that I already deleted the VM. In fact, I currently only have a single VM that has its own HD and is up and running fine! What can I do to delete that storage account that is probably sucking money from my pocket?

• Synaptics touchpad stops working randomly

  - by Jus12

  I have two laptops. One dell Vostro and other Vaio Z. Both have Synaptics (Yes, I have checked, and the original drivers were from Synaptics as well). On both laptops, the touchpad scrolling stops working at some arbitrary time and nothing seems to solve it except a reboot. Sometimes, it randomly starts working again. I have downloaded all latest drivers from OEM. Interestingly, when I run a program as Administrator, scrolling works in that window only. This problem is very odd. It happens without any reason and I've not been able to find a fix for more than a year. I have seen some unusual suggestions on forums (e.g., to "restore windows to a previous working state") but never any fix that solves this issue properly. I have tried installing latest drivers and I DO NOT want to restore windows to a previous working configuration. OS: Windows 7 64 bit Professional (Sony Vaio Z - VPCZ128GG) Windows 7 32 bit Professional (Dell) Edit: Temporary solution is to uninstall the synaptics driver and let Windows 7 use its default built in one. However, I really prefer the Synaptic driver because it activates the scroll button rather than the mouse wheel (useful in some apps such as MS Photo Editor)

• Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location

  - by Software Monkey

  My system in Windows 7 and fully up to date with all patches and options (except for Microsoft Silverlight, which I refuse to install). I get this error whenever I try to open an image using Windows Photo Viewer, such as when previewing from Explorer or when opening an image attachment to an email. I have already verified correct permissions to the file and all folders in the path. The strange thing is that every other program I have seems to open the images fine, including "Slideshow" from Windows Explorer. Even more strange, in WPV there is an "Open" menu that lists the other programs for images including GIMP and MS Paint and they open the very file that WPV is complaining about just fine. That should eliminate permissions as being the problem, especially since (logically at least) they are read/write while WPV is read-only. I have even edited and saved the images that WPV does not open. I am out of ideas, and searching for answer on the Web has resulted only in the same tired repitition of some flavor of "take ownership and reset permissions for the entire drive", which I have already done. And which is counter-indicated by the fact that only Windows Photo Viewer seems to have a problem. The one thing which is slightly unusual is that for normal files they are all on a second HDD mounted into C:, however for email attachments the temporary folder is C:\Temp\, which is directly on that drive.

• Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

  - by Dritan

  Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

• Browser says "Waiting for www.xyz.com" for a very long time

  - by Phil

  When I load my website (hosted with Ipage). The browser often takes an incredible long time saying "Waiting for www.xyz.com ..." before any elements of the site actually appear. After this "Waiting for" process, the text, images and everything else actually load quite fast. I contacted my host with my tracert result and they said they optimized my website database and increased the memory available to PHP on my account to 64 Mb.They also said they have checked the issue by accessing my website and found that it is loading fine without any slowness. It seems to be a temporary issue. Please try to access your website with different browser and network. I tried different browsers and networks but this "Waiting for" process always takes too long. My website is http://www.surreyextra.com/ . It's Wordpress and BuddyPress. I'm in the UK while Ipage host is placed in the USA, can this potentially be a problem? I have tried a number of optimizations, like minifying my CSS and JS files and use catching but the problem hasn't improved. So is it my host's fault, should I contact them again?

• Will a 2.4Ghz WAP intefere with a 5.0Ghz WAP if placed directly next to each other

  - by Dan

  This is mostly a curiosity question to people who know more about radio and wi-fi than I. The 2.4Ghz band is massively overpopulated near my house to the point of sometimes getting 1000ms pings to the router from only a few feet away. inSSIDer finds at least 10 broadcasting SSID's within around 15 seconds of starting, so this isn't a real surprise to me! Sometimes I can get good results by changing the channel to something like 3 or 8, but it's usually temporary as the others use Auto Channel and hop around. Now, the router I have is capable of 5.0Ghz, as is the laptop I type this on. Switching to 5.0Ghz gives superb results: I can download at ~90Mbps and get consistent 1ms pings. The problem is that only this laptop supports 5.0Ghz! My question: Would I still get decent 5.0Ghz performance if I place a 2.4Ghz access point directly next to my router? And, indeed, will 2.4Ghz continue working as 'normal'? Testing would be an obvious step, but I threw all my superfluous equipment out in a recent house move. My understanding is that I should get good performance, certainly in comparison to having two devices using the same frequency range, but I do believe there will be some impact by the virtue of them being directly next to each other. (Cabling is not an option due to it being a rented house)

• Administrator view all mapped drives

  - by kskid19

  In my understanding of security, an administrator should be able to view all connections to and from a computer - just as they can view all processes/owner, network connections/owning process. However, Windows 8 seems to have disabled this. As administrator running an elevated in Win Vista+ when you run net use you get back all drives mapped, listed as unavailable. In Windows 8, the same command run from an elevated prompt returns "There are no entries in the list". The behavior is identical for powershell Get-WmiObject Win32_LogonSessionMappedDisk. A workaround for persistent mappings is to run Get-ChildItem Registry::HKU*\Network*. This does not include temporary mappings (in my particular example it was created through explorer on an administrator account and I did not select "Reconnect at sign-in") Is there a direct/simple way for Administrator to view connections of any user (short of a script that runs under each user context)? I have read Some Programs Cannot Access Network Locations When UAC Is Enabled but I do not think it particularly applies. ServerFault has an answer, but it still does not address non-persistent drives How can I tell what network drives users have mapped?

• dpkg broken while upgrading Debian Etch to Lenny

• Windows ACL inheritance issues for FTP server and automated tools

  - by Martin Sall

  I have set up Cerberus FTP server. By default, Cerberus FTP service runs under SYSTEM ACCOUNT. Also I have some console applications which run as scheduled tasks. They are running under a dedicated "Utilities" user account which has "Log on as batch job" permissions. These console applications take uploaded FTP files, process them and then move them to some dedicated archive folder. The problem is that my console apps are throwing Security exceptions when trying to acces the uploaded files. I tried to give the Full control permissions on the ftproot folder for my "Utilities" account and I have checked that "Replace all Child object permissions with inheritable permissions from this object" checkbox, but it affects only current files. When new files are uploaded, they again are not accessible by my "Utilities" account. I tried to go another way and put Cerberus FTP service under "Utilities" account. Then I also needed to give "Utilities" account permissions on Cerberus Data folder in ProgramData. Still no luck - after this operation, Cerberus internal SOAP web service stopped working (although everything else seems to work). I need that SOAP service to be available, so running the Cerberus FTP under "Utilities" account seems to be not an option. Unless I find out, what else do I need to set up for that "Utilities" account to stop Cerberus from complaining. I guess, Cerberus is uploading files to some temporary folder and so those files get the permissions form that folder and keep the same permissions even after moved to the ftproot. What would be the right solution for this which would grant Cerberus FTP server and the "Utilities" account minimal needed permissions to access the contents of the ftproot folder?

• Windows Server 2008 - inexplicable system time jumps/glitches/inaccuracies

  - by Nathan Ridley

  I'm running a production web server on Windows Server 2008. On this server I have a database which logs certain user actions, but every now and again I inexplicably get database entries which, according to the record ID and the records immediately before and after, have the wrong time logged against them (7 days+ too old). For example, record ID 1001 will be for Dec 7, 11pm, 1002 will be for Dec 7, 11:01pm, then 1003 will be for Nov 28, 1:38am, then the next will be back on track again. The problem seems to occur in random records (or 2-3 records in a row) and crops up once every few days. This is absolutely baffling because there is only one place in the application that assigns this date/time value and it's simply the system UTC date. I have been synchronizing the system time to time-a.nist.gov (which I read in another article was a bit more reliable than the default time.windows.com) and it seems to occasionally get out of time anyway (3-4 minutes), but I'm speculating that occasionally the time server has a temporary glitch where the date changes to a drastically wrong value for a short space of time, then changes back. Either that, or the motherboard clock battery is screwed and the reason the time momentarily changes is that the motherboard loses the time and then the time synchronization puts it back again. Could either of my suspicions be right? Should I turn off time synchronization for a production server? Assigning dates to an event log where the dates are up to 2 weeks prior to the actual date is a severe problem I can't have when the next version of my application is released. Any suggestions or advice would be appreciated.

• switchover in postgresql

  - by user1010280

  I am using Postgresql 9.0 with Streaming replication. So, during switchover I follow these steps:- Get the server timestamp on primary. Get the current log position on primary. Set Verify Log location Verify Transaction Received Location Shutdown DB on production. Synchronize the transaction logs from PR to DR. Trigger a failover on the DR Database by creating the trigger file specified in recovery.conf Verify DB Mode on DR Copy the control file from from DR to primary. copy the temporary stats file from DR to primary. copy the history file from DR to primary. Create recovery.conf file. Start Database in standby mode in primary. Verify DB mode on PR At step (6), I have to copy last wal generated on Primary to standby and sync both PR and standby. but this thing takes time to copy files because this remote. So that postgres will keep seraching for wal for long time and after that it stops the server. So I want to know is there any way so that I can ask postgres to stop seraching or locating WAL after shutdown??? because postgres tries to locate this wal every 5 seconds. Please reply as soon as possible..its urgent...

• How to stop Firefox on an SSD from freezing when using the search box or submitting a form?

  - by sblair

  Firefox usually freezes for about a second whenever I search for something from the toolbar search box, when submitting a form, or when clearing the search box history. I suspect it has something to do with the auto-complete feature. Using Windows 7's Resource Monitor, the problem seems to be from the file: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\formhistory.sqlite-journal I believe this is a temporary file which caches database writes. The following screenshot shows the very high response times from six different searches, and that the queue length on drive C shoots off the scale: My Firefox profile is on an Intel X25-M G2 SSD. The problem doesn't seem to occur if I create a new profile on a hard disk drive. However, I'd like to know why the problem exists on the SSD in the first place (because it's an annoying problem which contradicts the reason I bought an SSD, and it might happen with other applications too), and how to prevent it. It still occurs if Firefox is started in safe mode, and with the recent beta versions. Updates: VACUUMing the Firefox profile databases does not help with this problem. The SSD Optimizer in the Intel SSD Toolbox does not help either.

• Organizing automatically Windows Files and Folders

  For Windows only, Organizing the eleventy-billion files you've got stuffed into folders on your hard drive is very "hard". For example, I have one folder on my computer that I save all web downloads to, regardless of file type, size or purpose. Many of the files are only temporary downloads, for instance setup files of applications that I test, demonstration videos that I watch once or documents that I want to read. Some files on the other hand are there to stay, and I used to move them out of the download folder manually in the past.

• Under what conditions will sendmail try to immediately resend a message instead of waiting for the standard requeue interval?

  - by Mike B

  CentOS 5.8 | Sendmail 8.14.4 I used to think that if SendMail experienced a temporary (400-class) error during delivery, it would place the message in a deferred queue (e.g. /var/spool/mqueue) and retry an hour later. For the most part, that appears to be the case. But every now and then, I'll notice log entries like this (email/domains renamed to protect the innocent :-) ) : Dec 5 01:43:03 foobox-out sendmail [11078]: qBE3l7js123022: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=124588, relay=exbox.foo.com. [10.10.10.10], dsn=4.0.0, stat=Deferred: 421 4.3.2 The maximum number of concurrent connections has exceeded a limit, closing transmission channel Dec 5 01:53:34 foobox-out sendmail [12763]: qBE3l7js123022: to=<[email protected]>, delay=00:10:31, xdelay=00:00:00, mailer=relay, pri=214588, relay=exbox.foo.com., dsn=4.0.0, stat=Deferred: 452 4.3.1 Insufficient system resources Dec 5 02:53:35 foobox-out sendmail [23255]: qBE3l7js123022: to=<[email protected]>, delay=01:10:32, xdelay=00:00:01, mailer=relay, pri=304588, relay=exbox.foo.com. [10.10.10.10], dsn=2.0.0, stat=Sent (<[email protected]> Queued mail for delivery) Why did Sendmail try again just 10 minutes after the first attempt and then wait another hour before trying again? If this is expected behavior, what scenarios will cause this faster requeue interval to occur?

• Changing a set-cookie header using mod_rewrite/mod_proxy

  - by olrehm

  I have a bunch of cgi scripts, which are served using HTTPS. They can only be reached on the intranet, not from the outside. They set a cookie with the attribute 'Secure', so that it can only be send via HTTPS. There is also a reverse proxy to one of these scripts, unfortunately using plain HTTP. When a response comes in from my cgi-script with a secure cookie, it is not being passed on via HTTP (after all, that is what that attribute is for). I need however, an exception to this rule. Is it possible to use mod_rewrite/mod_proxy or something similar, to change the set-cookie header in the response coming from my cgi script and remove the Secure, such that the cookie can be passed back to the user using the unsafe HTTP connection? I understand that this defeats the purpose of the Secure in the first place, but I need this as a temporary work around. I have searched the web and found how to add a set-cookie header using mod_rewrite, and I have also found how to retrieve the value of a cookie coming from the client in a cookie header. What I have not yet found is how to extract the set-cookie header received in the response of a script I am proxying for. Is that possible? How would I do that? Ole

• How can I create a VLAN on my extreme switch for a separate subnet/domain?

  - by drpcken

  I'm putting together a small active directory implementation for a buddy of mine. I currently have 2 servers (one is the primary domain controller) and a couple clients. I need to test and run updates on every machine on this domain, but I would have plug them into my current LIVE domain to get it internet access. From what I've read having two separate domains on a single subnet is a bad idea (even though it is temporary) so I don't want to risk messing anything up on my production domain. I'm pretty sure I can create a separate VLAN on my extreme 48 port switch and plug this smaller domain into it on a different subnet, but I don't know the commands. Both subnets would need internet access of course (one of the things I can't wrap my head around is routing internet traffic between subnets (gateway is on production subnet). Switch is a Summit x450e-48p My production domain is on subnet 192.168.200.0. My new domain I want to put online would go into subnet 192.168.10.0. A shove in the right direction would be greatly appreciated. Thank you!

• Intermittently uncommunicative subnets

  - by mhd

  Last week proved me a veritable Cassandra: I've always said that it's a bad idea to have only one firewall/router, without a backup or failover. And thus our Cisco PIX went haywire, refusing to route properly. And of course, the only one available here on short notice is me, and while I'm quite grounded in Linux, I'm really a developer not a sysadmin (the fact that this hit me on sysadmin appreciation day is a bit ironic). Anyway, this weekend I tried to hack up a temporary solution: I used an old server with enough NICs (two built-in, four on a card) to serve as a gateway and firewall. Due to some problems with the raid controller, I got only two router distros running, and between Untangle and Ebox I decided for the latter. Now everything is quite okay. I've got all the different subnets we've got here (all with separate switches) talking to each other and even to the internet (Cisco 2800 router, T1 lines). But from time to time (20-60 minute intervals), I get a total routing failure. Our main, office subnet can't talk to our server subnet and can't connect to the internet. This is not the end of a gradual slowdown, either everything's working perfectly or I get a total lack of communication for about two minutes each time. Now I'm a bit at wits end what to check. At least with the default EBox setup, nothing in /var/log shows anything weird and it doesn't exactly have lots of built-in monitoring tools. So I'm hoping someone here could give me some pointers about what to look out for. I did change the ethernet cable from the office switch to the firewall, with no results. I might change switches, although within the switch it seems to work ok enough. Edit: I'm not sure whether this is the sole cause of the problem, but after I noticed a few DHCP entries just before the last drop of connectivity, I tried to reproduce that. And alas, whenever I renew a DHCP connection, I can't access other subnets anymore. Running ISC DHCPD 3.0.6.

• Strange problem with Google Mail and IMAP on Outlook 2007

  - by Alex C.

  I work for a small non-profit organization. We have about 35 administrative employees who use e-mail. We're on a Windows network with a domain. Everyone is running XP Pro and Office 2007 with all updates/patches. We used to use POP3 mail through a local provider. However, we recently signed-up for a free Google Apps account, and we switched to IMAP mail through Google. Everyone uses Outlook 2007 as the client. For about ten days, everything was working fine. Yesterday afternoon, we suddenly developed a strange and annoying problem. Every time you send an e-mail message, a copy of your outgoing message shows up in your inbox. It's as if you're adding your own address to the CC: line of every message. Nothing has changed on our end. I was hoping that the problem was a temporary glitch that would resolve itself, but here we are about 24 hours later, and it's still happening. I searched Twitter, and there were a handful of vague messages about issues with Google mail and IMAP, but I didn't see any references to this specific problem. Any thoughts on what's going on here and how to fix it?

• Wake for Network Access Apache servr in OS X 10.8, followup

  - by Gary

  Sorry, I can't seem to post this response within the same thread. Thank you both (Zoredache and Gordon) for your answer. But the fix seems temporary. I entered the command you suggested, and it seemed to work: ...smith$ Registering Service ApacheNoDoz._http._tcp.local port 80 DATE: ---Fri 14 Sep 2012--- 12:04:15.813 ...STARTING... 12:04:16.566 Got a reply for service ApacheNoDoz._http._tcp.local.: Name now registered and active So, I checked for it on my G5: Browsing for _http._tcp Timestamp.....A/R Flags if Domain......Service Type...Instance Name (lots of Bonjour printers omitted)... 12:07:38.370..Add.....2..4 local.......... _http._tcp.........ApacheNoDoz 12:07:45.921..Rmv.....0..4 local..........._http._tcp.........ApacheNoDoz So, it was running at 12:07:38, at which time the host was asleep. But, shortly after, the activity seems to have been removed. I don't know why. Does this mean that I can never let the cpu sleep, or is there something else I have to set? Thanks, again.
