• Windows 8 taking 4+ mins to shutdown

  - by arnab321

  I did a fresh installation of Windows 8 64 bit, build 9200 (released on aug 16th). I installed the drivers and some basic softwares like NetBeans, mingw, iis server and php. For the first few times, it was restarting normally. But then at shutdown, it would show the shutdown screen for some seconds and then turn black for about 4 mins (similar to what happens at hibernation). I disabled the "fast startup" option in power options, but the problem still persists. Windows 7 and Ubuntu shut down normally. specs: 4gb ram, 750 gb sata hdd, solved by installing Windows Updates released during October. It was a serious bug in the OS, afaik. Now even hibernate takes upto 30 secs max. Still, win 8 is too buggy for release.

• Privileged command as part of cronjob

  - by user42756

  Hi, I'm facing a weired problem on a unix-based machine. Here is the story: I have a personal username/password on a unix machine with limited privileges. Whenever I need to execute some commands I have to substitute user using the su command, then I execute it normally. Now, I need to add a cronjob that uses such privileged commands so I added the cronjob on the crontab of the user I substituted to in order to have access to these commands. Strangely, it turned out to me that these commands fail to run for some reason as a cronjob although when I execute them directly from shell (after su) they work seamlessly. Why does this happen? Why do these commands not work as part of cronjobs? Thank you

• How can HAProxy improve availibility, or "how can I prevent my site from going down"? [closed]

  - by Joe Hopfgartner

  I am aware of what HAProxy does, but what if my HAproxy goes down? Or what if my DNS servers go down? Yes, dns is less the problem. However dns only solves to an IP and an IP is announced via BGP to be routed over some router. What if that router goes down? Of course if I have complicated application servers that are likely to fail HAProxy can significantly improve uptime. But my application isnt. In fact my application may very well just be delivering a small static html file via HTTP. Basically if any user anywhere types in MYDOMAIN.COM, I want the user to get SOMETHING on the screen other than a timeout or DNS resolution error. How can I do that? The point of entry is difficult. The so called "initial closure mechanism".

• Wireless Connection unstable with multiple devices connected

  - by KingIsulgard

  My wireless network works perfectly when only 1 device is connected. Super fast, full strength. But as soon as multiple devices are connected to the wireless network the connections become unstable (constantly losing connection with the internet, not the network itself). It's quite annoying. I have a Sitecom Wireless 300N XR Gigabit Router WL-306, which should be a decent router so I'm guessing there must be something wrong with my configuration. Does any of you know what might cause this? Thanks

• Failing RAM, or something else?

  - by Thanatos

  I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

• CSF Unresolved issue

  - by josephmarhee

  I began receiving service failures for CSF/LFD once the limit was reached in iptables preventing the service from working properly. I flushed all iptables rules, and redid by rules using CIDR rather than the individual IPs that were listed and the issue persists. Error: The VPS iptables rule limit (numiptent) is too low (1527/1536) - stopping firewall to prevent iptables blocking all connections, at line 1459 This is after restarting CSF, which gave me: You have an unresolved error when starting csf. You need to restart csf successfully to remove this warning CSF still seems to be trying to enforce rules that no longer exists (lists entire chains upon trying to be restarted,only to fail with that error). Any idea of what's going on?

• many-to-many-to-many, incl alignment of data from diff sources

  - by JefeCoon

  Re-factoring dbase to support many:many:many. At the second and third levels we need to preserve end-user 'mapping' or aligning of data from different sources, e.g. Order 17 FirstpartyOrderID => aha LineItem_for_BigShinyThingy => AA-1 # maps to 77-a LineItem_for_BigShinyThingy => AA-2 # maps to 77-b, 77-c LineItem_for_LittleWidget => AA-x # maps to 77-zulu, 77-alpha, 99-foxtrot LineItem_for_LittleWidget => AA-y # maps to 77-zulu, 99-foxtrot LineItem_for_LittleWidget => AA-z # maps to 77-alpha ThirdpartyOrderID => foo LineItem_for_BigShinyThingy => 77-a LineItem_for_BigShinyThingy => 77-b LineItem_for_BigShinyThingy => 77-c LineItem_for_LittleWidget => 77-zulu LineItem_for_LittleWidget => 77-alpha ThirdpartyOrderID => bar LineItem_for_LittleWidget => 99-foxtrot Each LineItem has daily datapoints reported from its own source (Firstparty|Thirdparty). In our UI & app we provide tools to align these, then we'd like to save them into the cleanest possible schema for querying, enabling us to diff the reported daily datapoints, and perform other daily calculations (which we'll store in the dbase also, fortunately that should be cake once we've nailed this). We need to map related [firstparty|thirdparty]line_items which have their own respective datapoints. We'll be using the association to pull each line_items collection of datapoints for summary and discrepancy calculations. I'm considering two options, std has_many,through x2 --or-- possibly (scary) ubermasterjoin table OptionA: order<<-->> order_join_table[id,order_id,firstparty_order_id,thirdparty_order_id] <<-->>line_item order_join_table[firstparty_order_id]-->raw_order[id] order_join_table[thirdparty_order_id]-->raw_order[id] raw_order-->raw_line_items[raw_order_id] line_item<<-->> line_item_join[id,LI_join_id,firstparty_LI,thirdparty_LI <<-->>raw_line_items line_item_join[firstparty_LI]-->raw_line_item[id] line_item_join[thirdparty_LI]-->raw_line_item[id] raw_line_item<<-->>datapoints = we rely upon join to store all mappings of first|third orders & line_items = keys to raw_* enable lookup of these order & line_item details = concerns about circular references and/or lack of correct mapping logic, e.g order--line_item--raw_line_items vs. order--raw_order--raw_line_items OptionB: order<<-->> join_master[id,order_id,FP_order_id,TP_order_id,FP_line_item_id,TP_line_item_id] join_master[FP_order_id & TP_order_id]-->raw_order[id] join_master[FP_line_item_id & TP_line_item_id]-->raw_line_item[id] = every combo of FP_line_item + TP_line_item writes a record into the join_master table = "theoretically" queries easy/fast/flexible/sexy At long last, my questions: a) any learnings from painful firsthand experience about how best to implement/tune/optimize many-to-many-to-many relationships b) in rails? c) any painful gotchas (circular references, slow queries, spaghetti-monsters) to watch out for? d) any joy & goodness in Rails3 that makes this magically easy & joyful? e) anyone written the "how to do many-to-many-to-many schema in Rails and make it fast & sexy?" tutorial that I somehow haven't found? If not, I'll follow up with our learnings in the hope it's helpful.. Thanks in advance- --Jeff

• Drupal 7 on Windows - File Module Problems

  - by TimothyP

  Installed Drupal 7 using the Web Platform installer on Windows 2008 For some reason, the file module, when you upload a file, uses the first few letters of the filename as the unique key to store in the database, which of course causes problems very fast. I'm wondering does anybody have a workaround for this? An AJAX HTTP request terminated abnormally. Debugging information follows. Path: /file/ajax/field_file/und/0/form-EBMatHzV5cZXcWvXJtdADSdyw7Id9-GIpFM_NCJg_a4 StatusText: n/a ResponseText: Error message PDOException: SQLSTATE[23000]: [Microsoft][SQL Server Native Client 10.0][SQL Server]Cannot insert duplicate key row in object 'dbo.file_managed' with unique index 'uri_unique'. in drupal_write_record() (line 6776 of ..........\includes\common.inc).

• MS Access ADP front end and SQL Server back end for field data collection?

  - by Brash Equilibrium

  I am an anthropologist. I am going to the field and will use a netbook to collect survey data. The survey forms will need to allow me to enter data into multiple tables, search tables, allow subforms, and be fast enough to not slow down my interview. I have considered storing the data in a SQL Server Express 2008 R2 server (there will be a lot of data) while using a Microsoft Access data project as a front end. To cut down the number of steps required to collect and store data, I'm considering using the netbook for both data storage and collection (after reading this article about SQL Server on a netbook). My questions are: (1) Is there a simpler solution that is also gratis (gratis because I already have a MS Access license from my workplace, and SQL Server Express is, obviously, free)? (2) Does my idea to store and collect data using the netbook make sense? Thank you.

• dig gets the right result from DNS server, but name still fails to resolve

  - by EMiller

  Under what conditions would the following occur? From a given OSX machine on an internal network: $~ cat /etc/resolv.conf nameserver 10.102.120.7 nameserver 10.102.120.2 From the same machine: $~ dig @10.102.120.7 in.local <snip> ... ;; QUESTION SECTION: ;in.local. IN A ;; ANSWER SECTION: in.local. 43200 IN A 10.102.123.30 <snip> ... And yet, this workstation cannot ping in.local, nor load pages hosted by apache on that machine. 10.102.123.30 is definitley up (2 OSX machines I know fail to resolve in.local - but other machines on the network can). I have also checked their /etc/hosts to see if anything there might interfere... Not sure what else to check...

• Virtualization Solution for Family Use

  - by Dave Potts

  I'm trying to put together a solution for my family (wife + three kids). At the moment I have one newish desktop and a couple of aging laptops. There are always arguments over who should have the fast desktop. I'm thinking I would like to invest in a new powerful server and then run virtual desktops for each user off the server so that each user would have the same experience regardless of which actual PC they were using. I would like to use just a Linux based desktop, but unfortunately I need to support some Windows games for the kids. I've not tried wine for the games but would be willing to give it a try. Any advice on what the setup should be would be most appreciated.

• Overheating on Ubuntu 12.04

  - by mati

  I have a Dell Inspiron Q17R with two graphic cards and I noticed that it is overheating. I installed Bumblebee, Jupiter and Flashblock, and I followed this guide as well, but it still got up to 74C. Is there anything more I can do? It still doesn't really seem to be working well and the fan keeps spinning really fast. After performing the following test: sensors in the terminal, this is what I got: Adapter: Virtual device temp1: +75.0°C (crit = +100.0°C) temp2: +75.0°C (crit = +100.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +68.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +68.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +65.0°C (high = +86.0°C, crit = +100.0°C) it doesn't look good.

• JAVA vs .NET Technology - Way 2 go Futher

  - by Sarang

  I have my subject .net acedemically. I also learned core-java and did a project as well. I took training from a java firm. Now, as a skill I do have knowledge as both language. But, it is creating a large problem to me that, which field I should chhose? Even if having better OOP funda, will it be easier for me to transfer from one-another in future ? Please suggest me a way. Also, we do have may technologies available at both side, like JSP, JSF, J2ME, Share Point, SilverLight etc. Which is better as per their reliabity point of view? Which are fast growing and useful technologies used mostly in current IT corporate world ? Are they easier to learn at fresher's point of view? Please answer. Perhaps, this answer may help me mostly to create my way to learn them and go further.

• How can I tell if my live web-server is overloaded?

  - by Nick G

  We have a live webserver which doesn't seem to be performing all that well. It's a Dell PowerEdge machine, a few years old (dual core, 4GB) which is hosting about 20 low-traffic websites. However it doesn't seem to be as fast as it used to be. How can we determine the cause of this? If it's website traffic, I would be expecting high CPU but CPU usage is quite low and hovers around the 15-30% mark except for very brief periods. I'm wondering perhaps, if rather than CPU performance being a problem, perhaps it's disk thrashing due to the constant read/writes of all the small web files and database queries. It has 4x 7200 RPM SATA drives in RAID 5. So is there a way to check that it's not disk thrashing?

• Can I use a micro ec2 instance as a load balancer for my other large ec2 instances?

  - by Ryan Detzel

  The issue I'm having is I want to upgrade that instance often(security patches, etc) but I'm affriad something will fail and the site will be down. So, I want to have another server setup and load balance between the two that way I can easily disable one, upgrade it and once it's working add it back in the mix and repeat. What kind of machine is needed for a load balancer? Would the micro instance work just fine? The site gets anywhere from 3-10k hits/day. I plan on using nginx as the load balancer.

• Hosts file in Apache keep changing for OS Linux Redhat [on hold]

  - by jack f

  I have installed Apache server. Two clients ex client_1 and client_2. The operation that we are performing on client_1 reflecting to client_2. We have etc/hosts file in our software install location which is keep on changing for client_2 with client_1 IP address.

• How to make a quiet laptop ? [closed]

  - by psihodelia

  Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be pdf/docs processing, real-time audio processing, web-surfing and skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend me any solution please? Thanks in advance!

  Hey guys, I am in search of a tool, with which I can organize my e-mail inbox!!

• Printing Booklet Page Size in Adobe Reader 4-in-1

  - by Justin Nathanael Waters

  So I have a 70 page pdf document that I'm trying to condense to a small booklet. I tried creating a formula to manually to perform it but it got ugly fast. 35,36,34,37,17,54,16,55,33,38,32,39,15,56,14,57,31,40,30,41,13,58,12,59 29,42,28,43,11,60,10,61,27,44,26,45,9,62,8,63,25,46,24,47,7,64,6,65 23,48,22,49,5,66,4,67,21,50,20,51,3,68,2,69,19,52,18,53,1,70 Once I print the booklet I should be able to cut the sheets in half and set the bottom half behind the top and staple it for a simple book. Which means Page 1 should have pages 35,36,17,54,34,37,16,55 Page 2 should have pages 33,38,15,56,32,39,14,57 And several pages later Page 9 should have pages 19,52,1,70,18,53 But manually doing this is a headache and it seems like the booklet function should contain functionality that can perform this. I'm using a commercial Konica Minolta C452

• Windows 7 doesn't connect to mapped drives at start up.....

  - by danbo

  We are testing Windows 7 (32bit version) and logon to a windows 2003 domain that runs a logon script whichs maps our drive letters. We have no control over the domain. Of our 7 test users, 5 continually recieve red X's on their network drives after they logon. Double clicking on them connects the drives, however, any aplpication that requires files on the fileserver will fail since it thinks it has no connection to the drive. We have tried several reg edits (Enable Linked connections, KeepConn), we have tried to find information in the event viewer to no avail. We have also looked at any differences in NIC driver versions (none). The other 2 computers that can connect without problem are local admins, but, if we logon to the 5 that have the problem with the local admin credentials we get the red x's as well??? This one is a real head scratcher......

• Cron process not starting

  - by vkris

  I have an ec2 image created with cron jobs. These jobs fail to run; I discovered the cron process in itself has not started. So, I included /usr/sbin/cron in /etc/rc.d/rc.local and created another image. But still for some reason the cron process does not start on bootup. If I restart the machine, the cron process runs. It doesn't run when it boots up! Any reason why this is happening? Also, is there any other alternatives for this ?

• How to handle knowledge handover effectively?

  - by Zizzencs

  Let's say a large enterprise opens a new office in (insert random location here) and want the new colleges up to speed as fast as possible. Let's also say this enterprise is a very typical one with a complex environment, lots of history and almost full lack of documentation. What's already been decided is that the new colleges will receive howto-style documentation for the most typical tasks and will get seme architecture documentation for some of the more complicated systems. Any ideas about improving this process? And more specifically, how should such a howto document look like to be helpful?

• Perl kill(0, $pid) in Windows always returning 1

  - by banshee_walk_sly

  I'm trying to make a Perl script that will run a set of other programs in Windows. I need to be able to capture the stdout, stderr, and exit code of the process, and I need to be able to see if a process exceeds it's allotted execution time. Right now, the pertinent part of my code looks like: ... $pid = open3($wtr, $stdout, $stderr, $command); if($time < 0){ waitpid($pid, 0); $return = $? >> 8; $death_sig = $? & 127; $core_dump = $? & 128; } else{ # Do timeout stuff, currently not working as planned print "pid: $pid\n"; my $elapsed = 0; #THIS LOOP ONLY TERMINATES WHEN $time > $elapsed ...? while(kill 0, $pid and $time > $elapsed){ Time::HiRes::usleep(1000); # sleep for milliseconds $elapsed += 1; $return = $? >> 8; $death_sig = $? & 127; $core_dump = $? & 128; } if($elapsed >= $time){ $status = "FAIL"; print $log "TIME LIMIT EXCEEDED\n"; } } #these lines are needed to grab the stdout and stderr in arrays so # I may reuse them in multiple logs if(fileno $stdout){ @stdout = <$stdout>; } if(fileno $stderr){ @stderr = <$stderr>; } ... Everything is working correctly if $time = -1 (no timeout is needed), but the system thinks that kill 0, $pid is always 1. This makes my loop run for the entirety of the time allowed. Some extra details just for clarity: This is being run on Windows. I know my process does terminate because I have get all the expected output. Perl version: This is perl, v5.10.1 built for MSWin32-x86-multi-thread (with 2 registered patches, see perl -V for more detail) Copyright 1987-2009, Larry Wall Binary build 1007 [291969] provided by ActiveState http://www.ActiveState.com Built Jan 26 2010 23:15:11 I appreciate your help :D For that future person who may have a similar issue I got the code to work, here is the modified code sections: $pid = open3($wtr, $stdout, $stderr, $command); close($wtr); if($time < 0){ waitpid($pid, 0); } else{ print "pid: $pid\n"; my $elapsed = 0; while(waitpid($pid, WNOHANG) <= 0 and $time > $elapsed){ Time::HiRes::usleep(1000); # sleep for milliseconds $elapsed += 1; } if($elapsed >= $time){ $status = "FAIL"; print $log "TIME LIMIT EXCEEDED\n"; } } $return = $? >> 8; $death_sig = $? & 127; $core_dump = $? & 128; if(fileno $stdout){ @stdout = <$stdout>; } if(fileno $stderr){ @stderr = <$stderr>; } close($stdout); close($stderr);

• PHPMyAdmin running very slow over internet but fine locally

  - by columbo

  I connect to PHPMyAdmin remotely on a Centos server using my local PC via Firefox. Usually it's fine but today it's really slow (2 minutes to load a page), sometimes timing out. Other connections to the server are fine. The SSH command line is as fast as ever as is the GNOME dekstop over SSH. In fact on the GNOME desktop I can run PHPMyAdmin locally from its browser and it's as quick as ever (which is a solution to the problem of course). I've checked the various log files and seen nothing unusual, I've logged into the MySQL command line and the database is running fine without any slowing what so ever. So it just seems to be slow when I access PHPMyAdmin on the server from the browser on my remote PC (I've tried IE and Firefox, both are slow). Has anyone experienced this or have any ideas what the issue could be. Connecting via CLI through tunnel works OK - problem is in phpMyAdmin for sure. Cheers

• WMI Notfication and database mirroring

  - by user22215

  Hi all I'm having a problem configuring a WMI alert that I would like to use with database mirroring. I'm running on Windows 2008 Enterprise X64 with Server 2008 Enterprise X64 also SQL Server has SP1 installed. Basically I click on alert select WMI after that I typed the below SQL statement SELECT * FROM DATABASE_MIRRORING_STATE_CHANGE WHERE DatabaseName = 'testmove' AND State = 8 I have also made sure the service broker is enabled for the msdb and all mirrored databases however I still can't get this to work basically the alert never fires. I'm testing with just the alert functionality I have not even added in the agent job yet. I tested this by right clicking on my mirrored database and forcing it to fail over. Any help with this problem would be much appreciated
