• Gnome 3 - Unable to change date and time

  - by Chris Harris

  I am running Arch Linux with Gnome 3. Unfortunately, although my time and date settings in /etc/rc.conf show that HARDWARECLOCK='UTC' and TIMEZONE='America/LosAngeles'. I continue to get the timezone of Europe/London. If I try to change the date and time via the GUI. It requires root access. After authorizing root access, the date and time may be changed; however, after closing the GUI window, it automatically reverts back to the previous incorrect timezone. I am able to use pool.ntp.org in order to sync my time to the correct one; however, this works only for the current session and is not fixed. This solution is inconvenient since there is not always network access. What other solutions are available for this problem?

• Tomcat's time problem when app inserts records in DB

  - by xain

  Hi, I have an apache 2 web server working with a tomcat 6 servlet container running on ununtu 9.1, integrated via mod_proxy. I have the following time mismatch problem: When apache log to its access-log file, the date/time is correct. When a grails app running on tomcat inserts date-related information in the DB, the time is three hours ahead Any tips on how to fix tomcat's datetime problem ? Thanks

• Time tracking similar to Paymo Plus on Debian

  - by aditya menon

  PaymoPlus is free (closed source but no fees) PaymoPlus sits in my System Tray all day, and records every window/tab I open I would like to know if a similar app exists for Debian. Paymo for Windows/Mac has the additional sweet feature of being able to drag and drop working windows/tabs and the time spent into the tasks, but one can live without this. I would at least need to know which tasks got how much time in a 'sum total' calculation so I can enter that time into my Paymo reporting. Any ideas? Paymo does have a desktop widget for Linux but it is a dumb (non-sentient) manual time entry tool, not like Paymo Plus automatically recording everything being done.

• Most precise way to calculate server response time.

  - by Quintin Par

  What's the most precise way to calculate the time taken by my server to execute a HTTP request. I don’t want to know the DNS resolution or the traceroute time, but just the server execution time. The is a follow up to my previous question to detect whats causing the delay between entering a domain name and load of the page

• Firefox add-on that tracks webpage load time including DNS retrieve time?

  - by Jonathan

  I used to have this add-on but now I forgot what it's called. Basically it can track any website's load time, DNS seeking time, time from host to javascript execution and HTML rendering, things like that. Got any suggestions for such an add-on for Firefox? Thanks.

• PowerShell to fetch a SQL Execution Plan

  - by Rob Farley

  With PowerShell becoming the scripting language of choice for many people, I’ve occasionally wondered about using it to analyse execution plans. After all, an execution plan is just XML, and PowerShell is just one tool which will very easily handle xml. The thing is – there’s no Get-SqlPlan cmdlet available, which has frustrated me in the past. Today I figured I’d make one. I know that I can write T-SQL to get an execution plan using SET SHOWPLAN_XML ON, but the problem is that this must be the only statement in a batch. So I used go, and a couple of newlines, and whipped up the following one-liner: function Get-SqlPlan([string] $query, [string] $server, [string] $db) { return ([xml] (invoke-sqlcmd -Server $server -Database $db -Query "set showplan_xml on;`ngo`n$query").Item( 0)) } (but please bear in mind that I have the SQL Snapins installed, which provides invoke-sqlcmd) To use this, I just do something like: $plan = get-sqlplan "select name from Production.Product" "." "AdventureWorks" And then find myself with an easy way to navigate through an execution plan! At some point I should make the function more robust, but this should be a good starter for any SQL PowerShell enthusiasts (like Aaron Nelson) out there.

• How to stay productive? What time management software is available?

  - by andrewsomething

  So since I started using askubuntu.com I've spent entirely too much time here answering other people's questions. Now maybe someone could help me with that by answering this one. I'm looking for time management software for Ubuntu. There are a number of these programs floating around for Windows. RescueTime is one that is very popular. The key features that I'd like to see in a linux app that RescueTime has are: Automatically records what application you are using, including what websites you visit. Reports and graphs on your time usage. Notifications for when you have spent too much time on "distractions." While RescueTime doesn't officially support linux, there is an open source RescueTime Linux Uploader. Unfortunately, it seems to only support Firefox and Epiphany for website tracking. I'm a Chromium user. The other major drawback to RescueTime is that it is a web service. I'd much rather not upload detailed information about how I spend my time to some third party. Google already knows too much about me as it is. Project Hamster, a GNOME time management app, comes so close. Sadly, it does not automatically track what you are doing. If I had enough discipline to manually report to an applet what I was up to, I doubt I'd need this. (How cool would it be if they provided some Zeitgeist integration to handle that part?)

• Possible Data Execution Prevention problem in Windows 7

  - by Joel in Gö

  I have a serious problem with my .Net program. It calls a native dll, and then crashes instantly because it can't find a native method. This is behaviour we have seen before, whereby the C# compiler, in its infinite wisdom, sets the flag that the program is DEP compatible, even if it calls a native dll which patently is not. We have the standard workaround for this, where the flag is set to Not DEP Compatible in a post-build step, and this works fine. Everywhere except on my machine. I have Windows 7 32bit, and the program works fine on the Win 7 64bit machines that we have, as well as on Vista and XP; we have not yet been able to check on another Win7 32bit. However, on my machine the DataExecutionPolicy_SupportPolicy is 0, i.e. we have successfully switched DEP off. The dll in question also works fine when called from a native program. We are running out of ideas... any help would be much appreciated!

• Controlled execution of computationally expensive tasks

  - by Sergio

  Say you have an application where a user is typing some text and as she types you'd want to perform some expensive computations in the background (related to the text that is being typed). Although you would like to do lots of things, your main priority is that the system responsiveness stay at acceptable levels so the user doesn't notice such a heavy load. Is there a way (ideally platform/language independent) to control what algorithms should be executed in the background based on the system load and responsiveness?

• is there an equivalent of a trigger for general stored procedure execution on sql server

  - by Arj

  Hi All, Hope you can help. Is there a way to detect when a stored proc is being run on SQL Server without altering the SP itself? Here's the requirement. We need to track users running reports from our enterprise data warehouse as the core product we use doesn't allow for this. Both core product reports and a slew of in-house ones we've added all return their data from individual stored procs. We don't have a practical way of altering the parts of the product webpages where reports are called from. We also can't change the stored procs for the core product reports. (It would be trivial to add a logging line to the start/end of each of our inhouse ones). What I'm trying to find therefore, is whether there's a way in SQL Server (2005 / 2008) to execute a logging stored proc whenever any other stored procedure runs, without altering those stored procedures themselves. We have general control over the SQL Server instance itself as it's local, we just don't want to change the product stored procs themselves. Any one have any ideas? Is there a kind of "stored proc executing trigger"? Is there an event model for SQL Server that we can hook custom .Net code into? (Just to discount it from the start, we want to try and make a change to SQL Server rather than get into capturing the report being run from the products webpages etc) Thoughts appreciated Thanks

• Trigger local program execution from browser

  - by DroidIn.net

  First and foremost: I know it's not right or even good thing to do but my current customer will not cave in. So here's what he is asking for (this is for in-house-behind-a-firewall-etc project). In the web report I need to supply a link which points to the executable script that lives on the universally mapped location (network file server). When user clicks on it it is expected to run on the local client starting local executable which should be pre-installed on the client's box. It should be agnostic to OS (Windows or Linux) and the browser used. Customer doesn't mind to click on angry pop-up alerts but he wants to do it once per client browser (or at minimum - session). QUESTION: Will trusted Java applet be able to do it? Or is the any other (better, simpler) ways of achieving the same? ActiveX control is out of question

• C# Step by Step Execution

  - by Sheldon

  Hi. I'm building an app that uses and scanner API and a image to other format converter. I have a method (actually a click event) that do this: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } The problem is that the if condition (scan_result == 1) is evaluated inmediatly, so it just don't work. How can I force the CLR to wait until the API return the convenient result. NOTE Just by doing something like: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); MessageBox.Show("Result = " + scan_result); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } It works and display the results. Is there a way to do this, how? Thank you very much!

• PHP pages working slow from time to time

  - by user1038179

  I have VPS with limit of 2GB of ram and 8 CPU cores. I have 5 sites on that VPS (one of them is just for testing, no visitors exept me). All 5 sites are image galleries, like wallpaper sites. Last week I noticed problem on one site (main domain, used for name servers, and also with most traffic, visitors). That site has two image galleries, one is old static html gallery made few years ago and another, main, is powered by ZENPhoto CMS. Also I have that same gallery CMS on another two sites on that same VPS (on one running site and on one just for testing site). On other two sites I have diferent PHP driven gallery. Problem is that after some time (it vary from 10 minutes to few hours after apache restart), loading of pages on main site becomes very slow, or I get 503 Service Temporarily Unavailable error. So pages becomes unavailable. But just that part with new CMS gallery, old part of site with static html pages are working fast and just fine. Also other two sites with same CMS gallery and other two with different PHP driven gallery are working fine and fast at the same time. I thought it must be something with CMS on that main site, because other sites are working nice. Then I tryed to open contact and guest book pages on that main site which are outside of that CMS but also PHP pages, and they do not load too, but that same contact php scipts are working on other sites at the same time. So, when site starts to hangs, ONLY PHP generated content is not working, like I said other static pages are working. And, ONLY on that one main site I have problems. Then I need to restart Apache, after restart everything is vorking nice and fast, for some time, than again, just PHP pages on main site are becomming slower. If I do not restart apache that slowness take some time (several minutes, hours, depending ot traffic) and during that time PHP diven content is loading very slow or unavailable on that site. After sime time, on moments everything start to work and is fast again for some time, and again. In hours with more traffic PHP content is loading slowly or it is unavailable, in hours with less traffic it is sometimes fast and sometimes little bit slower than usually. And ones again, only on that main site, and only PHP driven pages, static pages are working fast even in most traffic hours also other sites with even same CMS are working fast. Currently I have about 7000 unique visitors on that site but site worked nice even with 11500 visitors per day. And about 17000 in total visitors on VPS, all sites ( about 3 pages per unique visitor). When site start to slow down sometimes in apache status I can see something like this: mod_fcgid status: Total FastCGI processes: 37 Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 11300 39 28 7 Working 11274 47 28 7 Working 11296 40 29 3 Working 11283 45 30 3 Working 11304 36 31 1 Working 11282 46 32 3 Working 11292 42 33 1 Working 11289 44 34 1 Working 11305 35 35 0 Working 11273 48 36 2 Working 11280 47 39 1 Working 10125 133 40 12 Exiting(communication error) 11294 41 41 1 Exiting(communication error) 11277 47 42 2 Exiting(communication error) 11291 43 43 1 Exiting(communication error) 10187 108 43 10 Exiting(communication error) 10209 95 44 7 Exiting(communication error) 10171 113 44 5 Exiting(communication error) 11275 47 47 1 Exiting(communication error) 10144 125 48 8 Exiting(communication error) 10086 149 48 20 Exiting(communication error) 10212 94 49 5 Exiting(communication error) 10158 118 49 5 Exiting(communication error) 10169 114 50 4 Exiting(communication error) 10105 141 50 16 Exiting(communication error) 10094 146 50 15 Exiting(communication error) 10115 139 51 17 Exiting(communication error) 10213 93 51 9 Exiting(communication error) 10197 103 51 7 Exiting(communication error) Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7983 1079 2 149 Ready 7979 1079 11 151 Ready Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7990 1066 0 57 Ready 8001 1031 64 35 Ready 7999 1032 94 29 Ready 8000 1031 91 36 Ready 8002 1029 34 52 Ready Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7991 1064 29 115 Ready When it is working nicly there is no lines with "Exiting(communication error)" Active and Idle are time active and time since last request, in seconds.

• Web-based (intranet / non-hosted) timesheet / project tracking tools

  - by warren

  I realize some similar questions have been asked along these lines before, but from reading-through them today, it appears they don't match my use case. I am looking for a web-based, non-hosted time and project tracking tool. I've downloaded Collabtive so far, but am looking for other suggestions, too. My list of requirements: runs on standard LAMP stack non-hosted (ie, there is an option to download and run it on a local server) not a desktop/single-user application easy-to-use - my audience is a mix of technical and non-technical folks easy to maintain - when time for upgrading comes, I'd really like to not have to rebuild the app (a la ./configure ; make ; make install) needs to support multiple users free-form project additions: we don't have a central project management authority (users should be able to add whatever they're working on, not merely from a drop-down) Does anyone here have experience with such tools? It doesn't have to be free.. but free is always nice :)

• Finding open contiguous blocks of time for every day of a month, fast

  - by Chris

  I am working on a booking availability system for a group of several venues, and am having a hard time generating the availability of time blocks for days in a given month. This is happening server-side in PHP, but the concept itself is language agnostic -- I could be doing this in JS or anything else. Given a venue_id, month, and year (6/2012 for example), I have a list of all events occurring in that range at that venue, represented as unix timestamps start and end. This data comes from the database. I need to establish what, if any, contiguous block of time of a minimum length (different per venue) exist on each day. For example, on 6/1 I have an event between 2:00pm and 7:00pm. The minimum time is 5 hours, so there's a block open there from 9am - 2pm and another between 7pm and 12pm. This would continue for the 2nd, 3rd, etc... every day of June. Some (most) of the days have nothing happening at all, some have 1 - 3 events. The solution I came up with works, but it also takes waaaay too long to generate the data. Basically, I loop every day of the month and create an array of timestamps for each 15 minutes of that day. Then, I loop the time spans of events from that day by 15 minutes, marking any "taken" timeslot as false. Remaining, I have an array that contains timestamp of free time vs. taken time: //one day's array after processing through loops (not real timestamps) array( 12345678=>12345678, // <--- avail 12345878=>12345878, 12346078=>12346078, 12346278=>false, // <--- not avail 12346478=>false, 12346678=>false, 12346878=>false, 12347078=>12347078, // <--- avail 12347278=>12347278 ) Now I would need to loop THIS array to find continuous time blocks, then check to see if they are long enough (each venue has a minimum), and if so then establish the descriptive text for their start and end (i.e. 9am - 2pm). WHEW! By the time all this looping is done, the user has grown bored and wandered off to Youtube to watch videos of puppies; it takes ages to so examine 30 or so days. Is there a faster way to solve this issue? To summarize the problem, given time ranges t1 and t2 on day d, how can I determine the remaining time left in d that is longer than the minimum time block m. This data is assembled on demand via AJAX as the user moves between calendar months. Results are cached per-page-load, so if the user goes to July a second time, the data that was generated the first time would be reused. Any other details that would help, let me know. Edit Per request, the database structure (or the part that is relevant here) *events* id (bigint) title (varchar) *event_times* id (bigint) event_id (bigint) venue_id (bigint) start (bigint) end (bigint) *venues* id (bigint) name (varchar) min_block (int) min_start (varchar) max_start (varchar)

• In Fedora, Perl program cannot find Time::Piece library

  - by Eric Leschinski

  I have a Perl program named /usr/bin/octbatch running as a script on Fedora 17 Linux. When I run this command: /usr/bin/octbatch I get the error: Can't locate Time/Piece.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/bin/octbatch line 6. BEGIN failed--compilation aborted at /usr/bin/octbatch line 6. Here is the relevant lines of the Perl script: #!/usr/bin/perl -wT $ENV{PATH} = "/bin:/usr/bin:/usr/local/bin"; use strict; use POSIX qw(setsid :sys_wait_h); use Time::Piece; use Time::Local; I have to install Piece.pm so perl can find it. I've already installed it with this command (using the defaults): /usr/bin/perl -MCPAN -e install Time::Piece I have the Piece.pm file in /home/el/perl5/lib/perl5/x86_64-linux-thread-multi/ however when I run the octbatch command I get the same error as above. Like it can't even find it. Here is my PERL5LIB variable: el@defiant ~/gnuoctbluehost/single_stock_analysis $ env | grep PERL5 PERL5LIB=/home/el/perl5/lib/perl5/x86_64-linux-thread-multi:/home/el/perl5/lib/perl5 And the Piece.pm is located under /home/el/perl5/lib/perl5/x86_64-linux-thread-multi So my question is, Why is it not finding my Piece.pm file? And what are the ways I can get the @INC variable to include it. Or how do I make perl see it?

• Time Machine is getting stuck at "Preparing to Back Up" and my Trash isn't emptying

  - by zarose

  I have encountered two separate problems, but I am putting them in the same question in case they are related. First, my Trash would not empty. It seems to be getting stuck on certain files, because I will reset my Macbook and some of the files will be deleted, and then if I remove a file or two at random, more can be deleted. Some of these files had strange characters in their names. I tried changing the names to single characters, but this did not help. Next, I attempted to backup my Macbook using Time Machine. I plugged in the HDD I've been using for this, but every time I try to start the backup, Time Machine gets stuck at "Preparing to Back Up". I definitely need to know how to fix the Time Machine problem, but I am curious how to solve the trash problem as well, and whether or not these problems are related. EDIT: Console.app logged the following this morning before I left on a trip. I did not bring the HDD with me. 6/5/12 7:41:28.312 AM com.apple.backupd: Starting standard backup 6/5/12 7:41:46.877 AM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 7:41:58.368 AM com.apple.backupd: Backup failed with error: 19 6/5/12 7:59:08.999 AM com.apple.backupd: Starting standard backup 6/5/12 7:59:10.187 AM com.apple.backupd: Backing up to: /Volumes/Seagate 3TB Mac/Backups.backupdb 6/5/12 7:59:13.308 AM com.apple.backupd: Event store UUIDs don't match for volume: Macintosh HD 6/5/12 7:59:13.331 AM com.apple.backupd: Event store UUIDs don't match for volume: Blank 6/5/12 7:59:13.683 AM com.apple.backupd: Deep event scan at path:/ reason:must scan subdirs|new event db| 6/5/12 8:23:31.807 AM com.apple.backupd: Backup canceled. 6/5/12 8:23:33.373 AM com.apple.backupd: Stopping backup to allow backup destination disk to be unmounted or ejected. 6/5/12 9:51:21.572 PM com.apple.backupd: Starting standard backup 6/5/12 9:51:22.515 PM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 9:51:32.741 PM com.apple.backupd: Backup failed with error: 19

  Currently we have about 20 Mac OS 10.9 MacBook Pros (almost all with SSDs) backing up to individual USB drives. I'd like to consolidate these to one drobo thunderbolt drive array attached to a Mac Mini server (running 10.9 server) using time machine server. My question is, will this scale to 20 users? Examples I have seen seem to be 5 or 6 users tops, and this isn't easy for me to test (I'd rather not ask everyone to backup to the array and then switch back to USB drives if it brings our network to its knees). My primary concern is saturating our gigabit network, as time machine backs up every hour for every machine, so there would usually be a couple people backing up at any given time. We also have some people occasionally on our 802.11ac network and not on ethernet (usually connected via 802.11n until people upgrade to newer machines), but most of the time people are connected to our thunderbolt displays which have a gigabit ethernet connection on them. Our network topology is one 32 port gigabit switch with 5 smaller gigabit switches at each desk cluster. The mac mini server is connected directly to the top level switch. Update: Failing information from someone who has done this in practice, I suppose my question is really around how switches work. If three or four people are backing up simultaneously, and then other two (different) users transfer a file between each other, will they be able to transfer the file at gigabit speeds?

• How to use PHP Time function to set a time variable of '09:30', add a specific amount of seconds and

  - by Henry

  Hi guys, hopefully you can help me here. I have some code (please see below) which takes the current time, then adds specific seconds to the time and re-displays the time 1 minute in the future. Instead of the time being the current time, I want it to be a time which I set - say 9:30. Then I want to be able to add, for example 65 seconds and it shows me 9:31. Please can you show me how to change it from current time, to a specific time I can set myself. Thank you. <?php $my_time = date('h:i:s',time()); $seconds2add = 65; $new_time= strtotime($my_time); $new_time+=$seconds2add; echo date('h:i:s',$new_time); ?>

• Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

  - by Chris

  I found this Q&A (http://superuser.com/questions/148849/backup-mounted-drive-of-an-image-in-time-machine) and this prompted me to ask the following question: I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes. Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory. Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up? Thanks, Chris

• Users in the field and Time Machine

  - by Bart Silverstrim

  We have several users in the field with MacBooks. Because they're not always on the network, they save files locally to their notebooks. Normally I back things up by making quick copies to other media, but with the Macs they have the option to run Time Machine (and the way OS X is designed, they're heavily encouraged to use it.) Question; for maintaining Macs and data, how reliable and thorough is Time Machine for backup/restoration? Does it just back up the user's home directory, or can it restore the Mac if, for example, the drive fails? And are there options for "securing" the data like corporate backup software for Windows does, to encrypt the data on the time machine drive?
