• Nginx + php-fpm - recv() error

  - by Ilya Biryukov

  I get the follow error in the nginx log [error] 17734#0: *6643 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: [cut], server: [cut], request: "GET /venues HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "[cut]" I have a dedicated box with 8 gb ram, quad core chip. Good server. Nginx, php-fpm & mysql all latest versions running under ubuntu 10.04 I only get this when I stress test the server with siege. If I increase the number of concurrent connections to 100, I can get up to 20% of all requests to fail. Furthermore, I don't get this on pages that have no mysql queries. And only a few failures on pages with moderate number of queries. Bit, I'm not sure if that's got to do anything with it. I have a feeling this is something to do with php. But I can't figure it out. Any suggestions of where to even start looking? Update: and the php error log is silent. No record of anything going wrong

• Can I run Excel 2010 on a server?

  - by Glen Little

  This question is not about a person using Excel on a computer that happens to have an Windows Server OS. And it is not about using any Sharepoint services features! The question is about automated processes that use code (Office Automation) to open Excel files, manipulate them, run calculations, read data, save copies of the file and close the files... all in code. In previous versions of Excel the licensing agreement prevented use on a public server, notes from Microsoft warned about the problems trying to use Office Automation in a server environment, and we were warned that Excel was single threaded and not designed for use on a server. Most of the articles about this were written before Office 2010. But now, Excel 2010 is designed to work on a High Performance Computing server using HPC Services for Excel. One HPC document mentions "Windows HPC Server 2008 R2 includes a comprehensive pop-up manager that can handle occasional dialog boxes and pop-up messages". So my question is... is it now "safe" to run code that automates Excel 2010 on a "normal" server without using the HPC services? If not, can the HPC Services for Excel work on a single server? I don't need the high performance, distributed computing, aspect of HPC Services for Excel... just the ability to run Excel on a server. Can that now be done? Thanks, Glen

• Using WebDAV for automated downloads

  - by Geo Ego

  I currently manage a number of sites (at one point about a dozen, currently four, but soon growing into the dozens or hundreds) that serve a piece of software to clients at their remote locations. Our web server is Windows SBS Server 2k3, and the remote servers are Windows Server 2k3.When we have new versions of the software, I upload this new software to a specific directory and rename it; each time the clients boot, they pull their software from that specific directory. With just a few sites, it's no problem for me to RDP in and copy the files over. As the number grows, this will quickly become quite unwieldy. So I'm thinking that WebDAV would be part of a solution, so that I could simply push the newest version to our server (Windows SBS Server 2003) and make it available to the sites to grab. However, on the remote server side, what are some suggestions for automating the download? I only want the servers to download the files during downtime (between 3 AM and 9 AM), and I only want them to download if there is a new version available. I had thought of writing a program that checked the files on the WebDAV server at a regular interval, compared a hash of the current software to a hash of the software on the server, and only downloaded if they were different, but I'm wondering if there is something I am unaware of that can automate the process.

• Using the same Windows 8 Upgrade installer on multiple PCs

  - by Karan

  As per this article: You may transfer the software to another computer that belongs to you. … You may not transfer the software to share licenses between computers. But what if I have a bunch of PCs with a mix of XP/Vista/Windows 7? Can I purchase either the Windows 8 Pro Upgrade $40 (download only) or $70 (DVD) version (both of which come without a key) only once and use it to upgrade all the PCs? Since I'm not sharing the license and each PC has its own valid genuine license, it should be allowed, right, or is it illegal? Even if they want people to shell out $40/$70 for each PC, how would they enforce the use of the installer/media on only one PC each? EDIT: I have been given to believe by a source that the installer will only check for the previous OS' key, which is what is confusing me (I have never purchased an upgrade version before this, only full retail or pre-installed versions). Is this true or will I need to enter two keys to make the upgrade work, one for the previous version and then one for Windows 8? If the latter is the case, then the issue is solved since obviously the same Windows 8 key will not be valid for multiple PCs.

• Copy a website and preserve the file & folder structure

  - by DrStalker

  I have an old web site running on an ancient version of Oracle Portal that we need to convert to a flat-html structure. Due to damage to the server we are not able to access the administrative interface, and even if we could there is no export functionality that can work with modern software versions. It would be enough to crawl the website and have all the pages & images saved to a folder, but the file structure needs to be preserved; that is, if a page is located at http://www.oldserver.com/foo/bar/baz/mypage.html then it needs to be saved to /foo/bar/baz/mypage.html so that the various Javascript bits will continue to function. None of the web crawlers I've found have been able to do this; they all want to rename the pages (page01.html, page02.html etc) and break the folder structure. Is there any crawler out there that will recreate the site structure as it appears to a user accessing the site? It doesn't need to redo any of teh content of the pages; once rehosted the pages will all have the same names they did originally so links will continue to work.

• Prevent nginx from redirecting traffic from https to http when used as a reverse proxy

  - by Chris Pratt

  Here's my abbreviated nginx vhost conf: upstream gunicorn { server 127.0.0.1:8080 fail_timeout=0; } server { listen 80; listen 443 ssl; server_name domain.com ~^.+\.domain\.com$; location / { try_files $uri @proxy; } location @proxy { proxy_pass_header Server; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 120; proxy_pass http://gunicorn; } } The same server needs to serve both HTTP and HTTPS, however, when the upstream issues a redirect (for instance, after a form is processed), all HTTPS requests are redirected to HTTP. The only thing I have found that will correct this issue is changing proxy_redirect to the following: proxy_redirect http:// https://; That works wonderfully for requests coming from HTTPS, but if a redirect is issued over HTTP it also redirects that to HTTPS, which is a problem. Out of desperation, I tried: if ($scheme = 'https') { proxy_redirect http:// https://; } But nginx complains that proxy_redirect isn't allowed here. The only other option I can think of is to define the two servers separately and set proxy_redirect only on the SSL one, but then I would have duplicate the rest of the conf (there's a lot in the server directive that I omitted for simplicity sake). I know I could also use an include directive to factor out the redundancy, but I really want to keep just one conf file without any dependencies. So, first, is there something I'm missing that will negate the problem entirely? Or, second, if not, is there any other way (besides including an external file) to factor out the redundant config information so that I can separate out the HTTP and HTTPS versions of the server config?

• Arch Linux: How to handle patches which only you will use?

  - by user12932

  I'm using freerdp together with xmonad and it has been giving me a lot of trouble. The super key (or "windows key") is my mod key in xmonad and it has been interfering with my freerdp usage rather annoyingly. Whenever I switched workspaces (or did anything else in xmonad involving the super key), windows (controlled by the freerdp instance in focus) registered a keypress as well. This event combined with the loss of focus got the super key stuck in windows indefinitely: the press of the keys d and r would first show my desktop, then open the run dialog (as if I was pressing the windows key constantly). I've tried several versions of freerdp, but all exhibited this annoying behavior. So I resorted to patching freerdp myself to just ignore the left super key on my keyboard. I love free software for a lot of reasons (especially the ability to alter things like this myself), however I still find it annoying to patch and rebuild freerdp on all version (and dependency) changes. How do you deal with situations like this? Is there even a "right way" to resolve this issue?

• Nginx > Varnish > Gunicorn Error Too many Redirections

  - by kollo

  I have the following config: Nginx Varnish Gunicorn Django I want to cache 2 versions of same site (mobile & web) with Varnish. Gunicorn : WEB: gunicorn_django --bind 127.0.0.1:8181 MOBILE: gunicorn_django --bind 127.0.0.1:8182 Nginx: WEB: server { listen 80; server_name www.mysite.com; location / { proxy_pass http://127.0.0.1:8282; # pass to Varnish proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } MOBILE: server { listen 80; server_name m.mysite.com; location / { proxy_pass http://127.0.0.1:8282; # pass to Varnish proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } Varnish: default.vcl backend mobile_mysite { .host = "127.0.0.1"; .port = "8182"; } backend mysite { .host = "127.0.0.1"; .port = "8181"; } sub vcl_recv { if (req.http.host ~ "(?i)^(m.)?mysite.com$") { set req.http.host = "m.mysite.com"; set req.backend = mobile_mysite; }elsif (req.http.host ~ "(?i)^(www.)?mysite.com$") { set req.http.host = "mysite.com"; set req.backend = mysite; } if (req.url ~ ".*/static") { /* do not cache static content */ return (pass); } } The problem: On Nginx if I setup Mobile version with Varnish (port 8282) and let WEB version with Gunicorn( port 8181), MOBILE is cached by varnish, both WEB & MOBILE works but WEB is not cached. If I set the proxy_pass of WEB version to Varnish (port 8282) and restart Nginx I got an error when accessing web version (www.mysite.com) "Too many redirections" . I Think my problem come from the Varnish config file, as the site works well if I setup Nginx proxy_pass to Gunicorn ports (MOBILE & WEB).

• Road Warrior VPN Setup

  - by wobblycogs

  I apologise up front for the rather open ended nature of this question but I've got well out of my depth and could really do with some pointers. I need to set up a road warrior VPN solution which will allow our customers to securely access a number of services we provide for them. Customer machines will be running a variety of Windows versions from XP onwards with a variety of patch levels. Typically they will connect from the clients main offices but not always. It is safe to assume that all clients will be behind NATs but we may occasionally see a connection that isn't NAT'ed. Typical connection situation is therefore: Customer Laptop -- Router (NAT) -- Internet -- VPN Server + Firewall -- Server (Win 2008 R2, Non-routable IP) There will initially be a dozen or so people that could connect but that will grow quickly to around 100. It's unlikely that we'll see that many concurrent connections though, I imagine our total VPN throughput would be <50Mbps peak. What are my options for setting this up? I've been trying to set up a system like this using a MikroTik router for a few days but have struggled to get it working correctly, particularly with NAT'ed clients. I've had a quick look at OpenVPN and liked what I saw but I think it's unlikely our customers IT departments would allow the client to be installed. Finally I've looked at the Cisco ASA range but I'm on a fairly tight budget so this is less preferable but it looks like it would work pretty much out of the box. My fall back position is to connect the server directly and use the provided VPN + Firewall facilities but that is far from ideal as the number of servers is likely to grow over time.

• Terrible noises from subwoofer of ACER Aspire 6930 with Realtek sound chip

  - by OneWorld

  After approximately 5-15 min of listening to music my subwoofer begins to make terrible noises. He's just "coughing". That began after 6 months I had this computer. Now I found out, that I can temporarily fix this problem by "restarting" the audio stream of the application that plays music. For example reloading last.fm page (reloads the flash file). Another way to reset the audio playback is switching the speaker configuration shown below in the screenshot. According to many posts on the internet like http://www.tomshardware.co.uk/forum/52918-20-acer-aspire-6935g-speaker-problem ACER support isn't any help Exchanging hardware doesn't fix the problem Even the later models have this problem Turning off the volume of the subwoofer is not an option to me. I still have warranty (I bought an extension of one year). I already tried about 15 versions of the Realtek driver with no success. I am not sure but MAYBE the problem did not occur on the original windows vista that was shipped with this computer. However, I removed the original windows for good reasons (english). What do you suggest me? Did anyone fix this problem? Maybe by writing a script which resets the audio streams every 5 minutes? Shall I take the effort to deal with the acer support until they give me another model? (I won't have a computer than for a longer time, will spend money on telephone hotlines (1,30 EUR / min)......) Here are additional infos, if they are any help: Windows 7 64 Bit (Original was Windows Vista Home Premium 32 Bit) All specs Audio driver version:

• USPTO site asks for Quicktime Plug-in which I already have installed. Why?

  - by Kensai

  Whenever I try to watch the images of a patent in the USPTO site (example) using Firefox, the browser asks me to download the latest Quicktime, manually. This is totally strange because I already HAVE the latest plug-in (it even appears on my Firefox add-ons list). In the past I have only been able to see patent images using Safari. But never with Firefox. Is it a USPTO problem or a Mozilla one? Is there a way to fix the problem? edit: I can't see TIFF images neither with Internet Explorer (both 32-bit and 64-bit versions) nor with Chrome. All these browsers don't know how to open embedded TIFF images because they don't recognize the installed Quicktime plugin. A USPTO conspiracy to promote Safari? Come to think of it, I had this problem in my old computer as well. It had a 32-bit Vista OS, now I have 64-bit Windows 7. I hate TIFF and can't find Mozilla-specific information anywhere.. Arghh, am I the only one here with this freak problem?!

• Suddenly can't send E-Mails with Apple Mail to Gmail SMTP

  - by slhck

  Hi all, I have a weird problem that started just today. I am using Apple Mail on a Leopard machine, connecting to Gmail. Fetching e-mail works just fine. My SMTP settings are also correct. Still, I can't send mail, it will display a pop up saying that "transferring the content to the mail server" failed (translation from German, could be different in English OS X versions). I have verified the following: My SMTP settings are definitely correct. I have not changed them and the issue appeared today. Also, I went through the Apple online configuration for Gmail accounts and did not have to adjust any setting. I can run network diagnosis and it will connect to both POP and SMTP servers without a problem (all green lights) The Telnet details will show me the HELO message from the Gmail servers, so there's no authentication failure. Console.app will not show any messages related to "mail" when I try to send the mail, so there's no specific error message The mail I'm trying to send does not have an attachment, it is plaintext only I can login to gmail.com and send mails without a problem The recipient address exists and contains no syntax errors I can also not send mails to myself When using another IP and ISP (through VPN), it still doesn't work As for my settings: I connect to smtp.gmail.com and for advanced settings I choose password-based authentication with user: [email protected] and my password. I let Apple Mail try the default ports (for SSL and TLS, respectively). Again: I have not changed a thing between yesterday and today. What is causing that strange behavior? Any help would be much appreciated.

• How to diagnose remote assistance problem

  - by cantabilesoftware

  I have a long standing issue with remote assistance between a home and work PC. My wife and I both use MSN messenger and I used to be able to control her PC at home via MSN Remote Assistance. Some time ago however this stopped working and I don't know why. We're both running the latest versions of MSN Live Messenger and I've checked the appropriate firewall ports are open, but it still doesn't work and MSN just says something useless like "The person isn't responding". Any suggestions for how can I diagnose this? More info: I just tried direct Remote Desktop between work PC and home PC and it works fine - so I presume all the appropriate ports are open. Just Remote Assistance doesn't work. I'd like to get RA working so I can demonstrate how to do things remotely. With Remote Desktop the person at the other end gets booted off and can't see. With Remote Assistance they can follow along step by step. Some comments below suggest using other solutions, which is fine and do work, but there must be a way to diagnose RA and get it working. Experimenting with this some more, the notebook that I was using at work today that refused to connect works fine for remote assistance when I bring it home. So I guess this must be a problem with our network configuration at work. I've checked that 3389 is open on firewall on office router and remote desktop works both ways.... just not remote assistance. I've read that remote assitance won't work if client and server are both behind Non-UPnP/NAT routers. If one has UPnP it's supposed to work. Office router doesn't have UPnP enabled but my home one does. I've also scoured the event logs on both ends, nothing noteworthy - unless I'm looking in the wrong spot). Note (copied from comment): I've just tried ShowMyPC which is based on VNC and it works, but I'd still like to figure out what's wrong with RA - it's just bugging me. The question is only about Remote Assistance, no need to propose solutions based on other programs.[/edit by Gnoupi]

• Broken Python installation on CentOS 5.8

  - by Beckett

  I already searched for solution to my problem via Google and stackoverflow's search facility, but haven't found anything related specifically to it. Here's the problem: I needed python 2.7.3 on CentOS 5.8 machine which has only python 2.4.3 preinstalled. Also neither there's the suitable version in it's repositories nor I can upgrade installed version. That's why I decided to build python from source code. But I've made a mistake: instead of make altinstall I did make install thus changing default version of the current installation. It was before I found this article - How to install Python 2.7.3 on CentOS 6.2 . I guess 5.8 and 6.2 versions aren't different to the extent this article is inapplicable. After installation of new python version I installed pip, but once I tried to invoke it, I got "No module named pkg_resources" error. In order to solve this issue I installed setuptools from repository. But it had only led to another error: "Distribution Not Found". My final step was to follow the guide I posted the link to, but I was unable to perform last step: easy_install-2.7 virtualenv command threw "-bash: /usr/local/bin/easy_install-2.7: .: bad interpreter: Permission denied" error. Now when I try to invoke pip or pip-2.7 both commands raise the same error with different names of binaries after "-bash:". Is there any way to fix this problem, so I could install new python version (2.7.3) alongside with the preinstalled one (2.4.3) according to the guide? Any help will be appreciated. P.S.: yum is working fine, although it needs python to function, so I hope the damage I unknowingly caused isn't very severe. Also I'm not a native English speaker, so I apologize for possible occasional grammatical and/or spelling errors.

• How to take screenshots of WPF applications in correct size and content

  - by Thomas W.

  I usually take screenshots of single windows via the built-in key combination Alt+Print. Unfortunately this does not work well for more and more applications - all of them are WPF applications. Usually the screen shots have at least one of the following properties: the screenshot is larger than expected and contains parts of the screen around the actual window the screenshot has the correct size but includes parts of other windows, e.g. the Windows task bar. Of course the task bar might be in front of the window, but taking screen shots of "normal" programs works fine. How do I take screenshots of WPF application which are correct in size and content? I'd like to avoid the extra effort of checking all the screenshots for correctness, reproducing the situation, taking them again in case of issues or repairing/faking them manually in any pixel manipulation program (e.g. Paint.NET). I observe this on Windows 7 x64 SP 1, all official updates installed, but it might apply to other Windows versions as well (not tested yet). .NET 4.5 is installed. The application itself might only need the built-in .NET 3.5.1. It's reproducible on a virtual machine with the same settings. Examples: Screenshot of an application running in maximized mode. The screen shot includes parts of the task bar. Screenshot of a progress dialog which is behind the task bar. The screenshot also includes the task bar, while it doesn't for non WPF applications.

• lsof not showing what port a proc is listening on

  - by ericslaw

  I have many processes on a box listening on several ports. I am trying to map ports to pids. The problem is that lsof is not telling me what ports belong to which process. Given an apache listening on port 80, I can see it listening via netstat: user@host% netstat -an|grep LISTEN|grep 80 *.80 *.* 0 0 49152 0 LISTEN But when I try to map port 80 to a pid I get nothing: user@host% lsof -iTCP:80 -t When I try seeing what sockets that specific pid is using I get: user@host% lsof -lnP -p31 -a -i COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME libhttpd. 31 0 15u IPv4 0x6002d970b80 0t0 TCP *:65535 (LISTEN) Notice the *:65535 in the NAME column. Does anyone know why lsof is not reporting the port in use? I am running as root. I am using a mix of lsof and os versions: lsof v4.77 on Solaris10 sparc lsof v4.72 on Redhat4.2 etc I know that linux solutions can use "netstat -p", so I guess I'm only looking for why solaris isn't working, but I find lsof is frequently silent and not showing me expected data.

• Free antivirus solutions for Windows

  - by kristof

  What free antivirus solutions would you recommend? What are the limitations? What are the dangers of using free versions as opposed to paid solutions? E.g. are they less reliable? As mentioned by Tony, most of the free solutions are limited to personal use so the question will mainly focus on solutions for personal use. See if your antivirus of choice is already listed. Chances are it is. If you spot an answer that mentions one you already use, vote that up if you think it's a good solution. If you know of a feature or drawback not listed, or can include experiences in dealing with it, please edit the answer accordingly. If you know of any that can also be used at work please point this out. This covers all Windows platforms from XP, Vista and Windows 7. If you see an existing entry that needs an update or to add your testimonial, please do.

• Is there a free PDF printer / distiller that creates signable documents?

  - by Coderer

  I've used various methods (mentioned elsewhere on this site) to create PDFs, using a printer driver or converting from PostScript, etc. The common problem is that if I open any of the output files in the newer versions of Adobe Reader, there's an option to "Place Signature" but it's greyed out, or gives an error message that the feature has been disabled for this document. As far as I can tell, there's an option set somewhere in the document metadata that tells Reader "allow the user to sign this document", or don't. None of the free/open source tools that have been been linked to in other SU posts have had this listed as an option (though to be fair I haven't actually downloaded and tried all of them). Is there a tool that does this? Can I just poke a bit with a hex editor somewhere to turn on this functionality? I can sometimes get access to Acrobat Professional to turn on this option, but doing it for every desired case would be more work than I care to do. The current workaround for single-page documents is: Print the document to PDF (possibly via postscript) Open a single-page blank PDF with the "signable" bit turned on in Reader create a custom "stamp" using the Reader markup tools, by importing the printed-to document "stamp" an image of the printed document on the blank page, hoping to get it centered about right place a signature over the document-but-not-really you just stamped This obviously does not scale well at all. It would be much better if I could: Print the document to PDF Drag the document to a simple shortcut / tool / whatever Open the document in Reader Place a signature in the document ETA: Sorry, maybe I should have been clearer -- I'm talking about the certificate-based digital signing available in Adobe Reader, not adding a virtual ink signature. Also, any solution really would have to be available offline.

• Is there a keyboard shortcut to open a mounted TrueCrypt container?

  - by Lernkurve

  Problem I would like to open a mounted TrueCrypt container with a keyboard shortcut. Currently, I'm opening it by double-clicking the volume. See screenshot above. Instead of using the mouse, I'd like to use the keyboard. But there seems to be no way. Versions TrueCrypt 7.1.a Windows 7 64bit Failed attempts When you right-click on the volume, there is a "Open" command in the context menu. So, I've tried to open the context menu with the context menu key on the Windows keyboard. But strangely enough that does not open the context menu. I've also tried Shift+F10 to open the context menu, but that does not work either. There is no "Open" command in the menues (Volume, System, Favorites, Tools, Settings, Help), so I can't press for instance Alt+V to open a menu and go from there. I tried to use AutoHotKey to send a double-click command, but that does not work because the double-click is sent to the current mouse position and not the current selection, which would my selected TrueCrypt volume. There would be a HotKeys dialog in menu Settings Hot Keys... But there seems to be no way, to add or configure a hotkey for "Open". Workaround My current workaround is to tick "Open Explorer window for successfully mounted volume" in the menu Settings Preferences...

• What is the difference between these Pentium Extreme Edition CPUs?

  - by Giffyguy

  The CPU in question is the Pentium Extreme Edition 955. Intel's website shows four "versions", but for the most part they all look identical. They even share the same set of ordering codes. But one of them has a substantially lower TDP, which is seemingly unexplainable - since everything else is the same. Two of them say "LGA775, Tray" and I have no idea what "Tray" means either. Also, two of them have a different SPEC code. What I need to know is: What does "LGA775, Tray" mean? Why does the one CPU have a lower TDP? And what does that mean for me? Does that mean lower maximum power consumption? Does it mean the CPU may be more stable/endurant, because of a lower heat output? Why do two of them have a different SPEC code, and what does this mean? Finally, what does PLGA775 (as opposed to LGA775) mean, and do I need to be worried about that? Information from Intel's wbsite: Intel® Pentium® Processor Extreme Edition 955 (4M Cache, 3.46 GHz, 1066 MHz FSB) with SPEC Code 1 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 95 Watts BX80553955 SL94N 2 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL94N 3 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 130 Watts BX80553955 SL8WM 4 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL8WM

• MySQL select query result set changes based on column order

  - by user197191

  I have a drupal 7 site using the Views module to back-end site content search results. The same query with the same dataset returns different results from MySQL 5.5.28 to MySQL 5.6.14. The results from 5.5.28 are the correct, expected results. The results from 5.6.14 are not. If, however, I simply move a column in the select statement, the query returns the correct results. Here is the code-generated query in question (modified for readability). I apologize for the length; I couldn't find a way to reproduce it without the whole query: SELECT DISTINCT node_node_revision.nid AS node_node_revision_nid, node_revision.title AS node_revision_title, node_field_revision_field_position_institution_ref.nid AS node_field_revision_field_position_institution_ref_nid, node_revision.vid AS vid, node_revision.nid AS node_revision_nid, node_node_revision.title AS node_node_revision_title, SUM(search_index.score * search_total.count) AS score, 'node' AS field_data_field_system_inst_name_node_entity_type, 'node' AS field_revision_field_position_college_division_node_entity_t, 'node' AS field_revision_field_position_department_node_entity_type, 'node' AS field_revision_field_search_lvl_degree_lvls_node_entity_type, 'node' AS field_revision_field_position_app_deadline_node_entity_type, 'node' AS field_revision_field_position_start_date_node_entity_type, 'node' AS field_revision_body_node_entity_type FROM node_revision node_revision LEFT JOIN node node_node_revision ON node_revision.nid = node_node_revision.nid LEFT JOIN field_revision_field_position_institution_ref field_revision_field_position_institution_ref ON node_revision.vid = field_revision_field_position_institution_ref.revision_id AND (field_revision_field_position_institution_ref.entity_type = 'node' AND field_revision_field_position_institution_ref.deleted = '0') LEFT JOIN node node_field_revision_field_position_institution_ref ON field_revision_field_position_institution_ref.field_position_institution_ref_target_id = node_field_revision_field_position_institution_ref.nid LEFT JOIN field_revision_field_position_cip_code field_revision_field_position_cip_code ON node_revision.vid = field_revision_field_position_cip_code.revision_id AND (field_revision_field_position_cip_code.entity_type = 'node' AND field_revision_field_position_cip_code.deleted = '0') LEFT JOIN node node_field_revision_field_position_cip_code ON field_revision_field_position_cip_code.field_position_cip_code_target_id = node_field_revision_field_position_cip_code.nid LEFT JOIN node node_node_revision_1 ON node_revision.nid = node_node_revision_1.nid LEFT JOIN field_revision_field_position_vacancy_status field_revision_field_position_vacancy_status ON node_revision.vid = field_revision_field_position_vacancy_status.revision_id AND (field_revision_field_position_vacancy_status.entity_type = 'node' AND field_revision_field_position_vacancy_status.deleted = '0') LEFT JOIN search_index search_index ON node_revision.nid = search_index.sid LEFT JOIN search_total search_total ON search_index.word = search_total.word WHERE ( ( (node_node_revision.status = '1') AND (node_node_revision.type IN ('position')) AND (field_revision_field_position_vacancy_status.field_position_vacancy_status_target_id IN ('38')) AND( (search_index.type = 'node') AND( (search_index.word = 'accountant') ) ) AND ( (node_revision.vid=node_node_revision.vid AND node_node_revision.status=1) ) ) ) GROUP BY search_index.sid, vid, score, field_data_field_system_inst_name_node_entity_type, field_revision_field_position_college_division_node_entity_t, field_revision_field_position_department_node_entity_type, field_revision_field_search_lvl_degree_lvls_node_entity_type, field_revision_field_position_app_deadline_node_entity_type, field_revision_field_position_start_date_node_entity_type, field_revision_body_node_entity_type HAVING ( ( (COUNT(*) >= '1') ) ) ORDER BY node_node_revision_title ASC LIMIT 20 OFFSET 0; Again, this query returns different sets of results from MySQL 5.5.28 (correct) to 5.6.14 (incorrect). If I move the column named "score" (the SUM() column) to the end of the column list, the query returns the correct set of results in both versions of MySQL. My question is: Is this expected behavior (and why), or is this a bug? I'm on the verge of reverting my entire environment back to 5.5 because of this.

• JVM disappeared on Mac OS X Snow Leopard 10.6.8

  I'm working in Eclipse one night, (also using Android's DDMS from the commandline). The next morning, I open the lid... attempt to run Eclipse and get an error. me$ sudo /Applications/eclipse/eclipse JavaVM: requested Java version ((null)) not available. Using Java at "" instead. JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib So I then attempt to find out where my JDKs are pointed: me$ ls -la /System/Library/Frameworks/JavaVM.framework/Versions/ total 64 drwxr-xr-x 12 root wheel 408 Nov 16 10:44 . drwxr-xr-x 12 root wheel 408 Sep 7 09:39 .. lrwxr-xr-x 1 root wheel 5 Sep 7 17:07 1.3 -> 1.3.1 drwxr-xr-x 3 root wheel 102 Dec 2 2009 1.3.1 lrwxr-xr-x 1 root wheel 10 Sep 7 17:07 1.4 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Sep 7 17:07 1.4.2 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Sep 7 17:07 1.5 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Sep 7 17:07 1.5.0 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Sep 7 17:07 1.6 -> CurrentJDK drwxr-xr-x 9 root wheel 306 Nov 16 10:44 A lrwxr-xr-x 1 root wheel 1 Sep 7 17:07 Current -> A lrwxr-xr-x 1 root wheel 59 Sep 7 17:07 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents Everything looks normal so far... me$ ls -la /System/Library/Java/JavaVirtualMachines/ total 0 drwxr-xr-x 2 root wheel 68 Nov 16 10:44 . drwxr-xr-x 5 root wheel 170 Nov 16 10:44 .. Apparently, my virtual machines have been deleted or moved? I'll probably be able to just re-install Java, but does anyone have any insight into why this may have happened or how to prevent in the future?

• What to do when a device has no driver for Windows 7 but it has Vista, XP drivers

  - by Mehper C. Palavuzlar

  This has always been a bothersome matter for me. Some devices (printers, scanners, etc.) have drivers for older versions of Windows (Vista, XP, 2000, NT) but no driver for Windows 7. What are my chances to install such devices on Windows 7? Example case: I have a Sharp printer & scanner (Sharp AR-122E N) which I have used for my old Windows XP based PC. Now I want to install it on a Windows 7 x64 based PC. Windows 7 cannot load its driver. I used the original driver CD but when I run the setup.exe (which is included in AR122EN111.exe, 6713KB), it says Cannot install driver on this operating system. Supported operating systems are: Windows 2000, XP, Vista. I tried to install the driver using compatibility settings. I tried Windows Vista and Windows XP SP3, but to no avail. The setup gave the same error. I also googled for Windows 7 driver for "Sharp AR-122E N" but it only listed the original driver that I tried. The official site of Sharp does not even list the driver for this product. In the past, the compatibility setting workaround did work for some devices, but this time it failed. What else can I do to overcome this problem?

• Java Deployment and Configuration (1.6.0_21)

  - by user125137

  Sofware: Java Runtime Environment 1.6.0_21 OS: Windows XP Professional 32-Bit, SP3 Situation: a new piece of web based software is being deployed this week and prior to this all the company desktops need to be set up to meet the requirements of this software. One of these requirements is JRE 1.6.0_21. I have successfully scripted the removal of all other Java versions and the installation of the required version, however I cannot get it configured properly. One of the requirements is that the Java console be set to disabled - if it is not it can cause an issue with a particular function. I have pushed out a deployment.config and deployment.properties but the console just will not disable itself.. I know the config is being read correctly because the update tab is being correctly disabled and removed. deployment.config: deployment.system.config=file\:C\:/WINDOWS/Sun/Java/Deployment/deployment.properties deployment.system.config.mandatory=true deployment.properties: #deployment.properties #Fri Jun 15 09:34:31 EST 2012 deployment.version=6.0 deployment.console.startup.mode=DISABLE deployment.javaws.autodownload=NEVER deployment.javaws.autodownload.locked= There is no change if I set the console to ENABLE either - it remains on the default of hidden. I'm sure I can disable the console with a registry change of some form but my preference is to have it done via the deployment files as it gives the option of centralising the properties file to a network share if we wish. If anyone has any suggestions it would be appreciated.
