• Truncating long strings with CSS: feasible yet?

  - by Sam Stokes

  Is there any good way of truncating text with plain HTML and CSS, so that dynamic content can fit in a fixed-width-and-height layout? I've been truncating server-side by logical width (i.e. a blindly-guessed number of characters), but since a 'w' is wider than an 'i' this tends to be suboptimal, and also requires me to re-guess (and keep tweaking) the number of characters for every fixed width. Ideally the truncation would happen in the browser, which knows the physical width of the rendered text. I've found that IE has a text-overflow: ellipsis property that does exactly what I want, but I need this to be cross-browser. This property seems to be (somewhat?) standard but isn't supported by Firefox. I've found various workarounds based on overflow: hidden, but they either don't display an ellipsis (I want the user to know the content was truncated), or display it all the time (even if the content wasn't truncated). Does anyone have a good way of fitting dynamic text in a fixed layout, or is server-side truncation by logical width as good as I'm going to get for now?

• Display shift when adding rows to UITableView

  - by Kamchatka

  Hello, I have a UITableView displaying an underlying NSFetchedResultsController. When the fetchedResultsController is updated, - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { is called. And the following is executed: case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:shiftedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; The cellForRowAtIndexPath is only called for the new line (which is logical) The problem is however that all the values displayed in the rows of the table view are shifted down. The first row displays its title. The second rows displays the first row's title. The third row the second row's title etc. If I repeat that, the third row will display the second's row title, the fourth the third row's title etc. I don't understand what can happen, especially because cellForRowAtIndexPath is only called for the new line (which is logical) and not for all these lines. Additionally, if I click on these lines which have the wrong title, it opens the right document (didSelectRowAtIndexPath works correctly with the indexPath) Any clue of what could happen? Thanks!

• Faster way to split a string and count characters using R?

  - by chrisamiller

  I'm looking for a faster way to calculate GC content for DNA strings read in from a FASTA file. This boils down to taking a string and counting the number of times that the letter 'G' or 'C' appears. I also want to specify the range of characters to consider. I have a working function that is fairly slow, and it's causing a bottleneck in my code. It looks like this: ## ## count the number of GCs in the characters between start and stop ## gcCount <- function(line, st, sp){ chars = strsplit(as.character(line),"")[[1]] numGC = 0 for(j in st:sp){ ##nested ifs faster than an OR (|) construction if(chars[[j]] == "g"){ numGC <- numGC + 1 }else if(chars[[j]] == "G"){ numGC <- numGC + 1 }else if(chars[[j]] == "c"){ numGC <- numGC + 1 }else if(chars[[j]] == "C"){ numGC <- numGC + 1 } } return(numGC) } Running Rprof gives me the following output: > a = "GCCCAAAATTTTCCGGatttaagcagacataaattcgagg" > Rprof(filename="Rprof.out") > for(i in 1:500000){gcCount(a,1,40)}; > Rprof(NULL) > summaryRprof(filename="Rprof.out") self.time self.pct total.time total.pct "gcCount" 77.36 76.8 100.74 100.0 "==" 18.30 18.2 18.30 18.2 "strsplit" 3.58 3.6 3.64 3.6 "+" 1.14 1.1 1.14 1.1 ":" 0.30 0.3 0.30 0.3 "as.logical" 0.04 0.0 0.04 0.0 "as.character" 0.02 0.0 0.02 0.0 $by.total total.time total.pct self.time self.pct "gcCount" 100.74 100.0 77.36 76.8 "==" 18.30 18.2 18.30 18.2 "strsplit" 3.64 3.6 3.58 3.6 "+" 1.14 1.1 1.14 1.1 ":" 0.30 0.3 0.30 0.3 "as.logical" 0.04 0.0 0.04 0.0 "as.character" 0.02 0.0 0.02 0.0 $sampling.time [1] 100.74 Any advice for making this code faster?

• Appropriate uses of Monad `fail` vs. MonadPlus `mzero`

  - by jberryman

  This is a question that has come up several times for me in the design code, especially libraries. There seems to be some interest in it so I thought it might make a good community wiki. The fail method in Monad is considered by some to be a wart; a somewhat arbitrary addition to the class that does not come from the original category theory. But of course in the current state of things, many Monad types have logical and useful fail instances. The MonadPlus class is a sub-class of Monad that provides an mzero method which logically encapsulates the idea of failure in a monad. So a library designer who wants to write some monadic code that does some sort of failure handling can choose to make his code use the fail method in Monad or restrict his code to the MonadPlus class, just so that he can feel good about using mzero, even though he doesn't care about the monoidal combining mplus operation at all. Some discussions on this subject are in this wiki page about proposals to reform the MonadPlus class. So I guess I have one specific question: What monad instances, if any, have a natural fail method, but cannot be instances of MonadPlus because they have no logical implementation for mplus? But I'm mostly interested in a discussion about this subject. Thanks! EDIT: One final thought occured to me. I recently learned (even though it's right there in the docs for fail) that monadic "do" notation is desugared in such a way that pattern match failures, as in (x:xs) <- return [] call the monad's fail. It seems like the language designers must have been strongly influenced by the prospect of some automatic failure handling built in to haskell's syntax in their inclusion of fail in Monad.

• How to differentiate between exceptions i can show the user, and ones i can't?

  - by Ian Boyd

  i have some business logic that traps some logically invalid situations, e.g. trying to reverse a transaction that was already reversed. In this case the correct action is to inform the user: Transaction already reversed or Cannot reverse a reversing transaction or You do not have permission to reverse transactions or This transaction is on a session that has already been closed or This transaction is too old to be reversed The question is, how do i communicate these exceptional cases back to the calling code, so they can show the user? Do i create a separate exception for each case: catch (ETransactionAlreadyReversedException) MessageBox.Show('Transaction already reversed') catch (EReversingAReversingTransactionException) MessageBox.Show('Cannot reverse a reversing transaction') catch (ENoPermissionToReverseTranasctionException) MessageBox.Show('You do not have permission to reverse transactions') catch (ECannotReverseTransactionOnAlredyClosedSessionException) MessageBox.Show('This transaction is on a session that has already been closed') catch (ECannotReverseTooOldTransactionException) MessageBox.Show('This transaction is too old to be reversed') Downside for this is that when there's a new logical case to show the user: Tranasctions created by NSL cannot be reversed i don't simply show the user a message, and instead it leaks out as an unhandled excpetion, when really it should be handled with another MessageBox. The alternative is to create a single exception class: `EReverseTransactionException` With the understanding that any exception of this type is a logical check, that should be handled with a message box: catch (EReverseTransactionException) But it's still understood that any other exceptions, ones that involve, for example, an memory ECC parity error, continue unhandled. In other words, i don't convert all errors that can be thrown by the ReverseTransaction() method into EReverseTransactionException, only ones that are logically invalid cause of the user.

• Advice on Minimizing Stored Procedure Parameters

  - by RPM1984

  Hi Guys, I have an ASP.NET MVC Web Application that interacts with a SQL Server 2008 database via Entity Framework 4.0. On a particular page, i call a stored procedure in order to pull back some results based on selections on the UI. Now, the UI has around 20 different input selections, ranging from a textbox, dropdown list, checkboxes, etc. Each of those inputs are "grouped" into logical sections. Example: Search box : "Foo" Checkbox A1: ticked, Checkbox A2: unticked Dropdown A: option 3 selected Checkbox B1: ticked, Checkbox B2: ticked, Checkbox B3: unticked So i need to call the SPROC like this: exec SearchPage_FindResults @SearchQuery = 'Foo', @IncludeA1 = 1, @IncludeA2 = 0, @DropDownSelection = 3, @IncludeB1 = 1, @IncludeB2 = 1, @IncludeB3 = 0 The UI is not too important to this question - just wanted to give some perspective. Essentially, i'm pulling back results for a search query, filtering these results based on a bunch of (optional) selections a user can filter on. Now, My questions/queries: What's the best way to pass these parameters to the stored procedure? Are there any tricks/new ways (e.g SQL Server 2008) to do this? Special "table" parameters/arrays - can we pass through User-Defined-Types? Keep in mind im using Entity Framework 4.0 - but could always use classic ADO.NET for this if required. What about XML? What are the serialization/de-serialization costs here? Is it worth it? How about a parameter for each logical section? Comma-seperated perhaps? Just thinking out loud. This page is particulary important from a user point of view, and needs to perform really well. The stored procedure is already heavy in logic, so i want to minimize the performance implications - so keep that in mind. With that said - what is the best approach here?

• PHP: Three item validation comparison

  - by DavidYell

  I have 3 featured product panels on the homepage, and I'm writing a CMS page for it. I'm trying to validate the items. They are selected via three <select> elements, featured1, featured2 and featured3. The default is <option value="0" selected>Select an element</option> I need to validate the $_POST to ensure that the user hasn't selected the same product for more than one of the panels. I have worked out that each $_POST needs to be $_POST['featuredN'] > 0 but I can't seem to find a logical way of processing the 7 potential outcomes. Using a logic table, where 1 is a set value. 1 2 3 ------- 0 0 0 1 1 1 1 0 0 0 1 0 0 0 1 1 1 0 0 1 1 If an item is 0, then I will not update it, but I want the user to be able to update a single item if needs be. I cannot find a logical way to see if the item is not 0, and then compare it to another item if that also is not 0. So far my colleague suggested, adding up the values. Which works to see if condition 1 0 0 0 is not met. I have a vague feeling that some form of recursive function might be in order, but I can't quite get my brain to help me on this one! So to the collective brain! :)

• HP ProCurve & Cisco switches interoperability

  - by Kamil Z

  I have a couple of questions regarding Cisco and HP ProCurve interoperability. Here's a link to pdf with my network topology. Can someone help me with basic VLAN configuration in such topology? Below there are some details of my configuration: # m_management_2 interface FastEthernet0/43 switchport access vlan 250 switchport mode access spanning-tree port-priority 32 spanning-tree cost 100 # MTA2-swmgmt1 vlan 1 name "DEFAULT_VLAN" untagged 1-48 ip address 10.10.249.190 255.255.255.128 exit # MTA2-swtr1 vlan 1 name "DEFAULT_VLAN" untagged 1-14,16-48 no ip address no untagged 15 exit vlan 100 name "MTA Mgmt" untagged 15 ip address 10.10.249.188 255.255.255.128 exit # MTA2-swtr2 vlan 1 name "DEFAULT_VLAN" untagged 1-14,16-48 no ip address no untagged 15 exit vlan 100 name "MTA Mgmt" untagged 15 ip address 10.10.249.189 255.255.255.128 exit I don't post MTA2-bcsw[12] configuration, because I wasn's successfull in this one yet. Every time I configure VLANs on MTA2-bcsw[12] Fa0/24 interface on m_management_2 goes down bacause of receiving tagged BPDUs on access port (there are no VLANs configured on MTA2-swmgmt1 because of fact that only 250 VLAN is allowed in this switch. Is it correct?). Can someone provide me some basic configuration for this topology? Second thing I want to ask is concept of connection from MTA2-swmgmt1 to MTA2-swtr[12] HP switches for the sake of management. How to configure such ports on HP switches (managed switch and manager switch). Is my actual configuration correct?

• Recursive move utility on Unix?

  - by Thomas Vander Stichele

  Sometimes I have two trees that used to have the same content, but have grown out of sync (because I moved disks around or whatever). A good example is a tree where I mirror upstream packages from Fedora. I want to merge those two trees again by moving all of the files from tree1 into tree2. Usually I do this with: rsync -arv tree1/* tree2 Then delete tree1. However, this takes an awful lot of time and disk space, and it would be much easier to be able to do: mv -r tree1/* tree2 In other words, a recursive move. It would be faster because first of all it would not even copy, just move the inodes, and second I wouldn't need a delete at the end. Does this exist ? As a test case, consider the following sequence of commands: $ mkdir -p a/b $ touch a/b/c1 $ rsync -arv a/ a2 sending incremental file list created directory ./ b/ b/c1 b/c2 sent 173 bytes received 57 bytes 460.00 bytes/sec total size is 0 speedup is 0.00 $ touch a/b/c2 What command would now have the effect of moving a/b/c2 to a2/b/c2 and then deleting the a subtree (since everything in it is already in the destination tree) ?

• IIS 6 ASP.NET default handler-mappings and virtual directories

  - by mlauter

  I'm having a problem with setting a default mapping in IIS 6. I want to secure *.HTML files with ASP.NET forms authentication. The problem seems to have something to do with using virtual directories to hold the html files. Here's how it's setup: sample directory tree c:/inetpub/ (nothing in here) d:/web_files/my_web_apps d:/web_files/my_web_apps/app1/ d:/web_files/my_web_apps/app2/ d:/web_files/my_web_apps/html_files/ app1 and app2 both access the same html_files directory, so html_files is set as a virtual directory in the web apps in IIS... sample web directory tree //app1/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) //app2/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) If I put a file called test.html in the root of //app1/ and then add the default mapping to the asp.net dll and setup my security on the root folder with deny="?", then accessing test.html works exactly as expected. If I'm not authenticated, it takes me to the login.aspx page, and if I am authenticated then it displays test.html. If I put the test.html file in the html_files directory I get a totally different behavior. Now the login.aspx page loads and I stuck some code in to check if I was still authenticated: <p>autheticated: <%=User.Identity.IsAuthenticated%></p> I figured it would say false because why else would it bother to load the login page? Nope, it says true - so it knows i'm authenticated, but it won't give me access to the test.html file. I've spent several hours on this and haven't been able to solve it. I'm going to spend some more time on google to see if I've missed something. Fingers crossed.

• Rsync: General file/folder synchronization

  - by Rey Leonard Amorato

  I have a file server, which is in-charge of pulling a folder tree from multiple workstations on a daily basis. My current method for this is by using rsync, (which works pretty well provided directory names and/or files remain the same) however, when files are renamed or moved about within subdir1, rsync will copy them over to the server, creating duplicates. I have to manually find and delete extraneous files/folders that had been left on the server during previous syncs. Note that I cannot use rsync's --delete flag because any sync from a workstation will then mirror that particular folder tree, instead of merging them to the server. Visual diagram: Server: Workstation1 Workstation2 Workstation(n) Folder* Folder* Folder* Folder* -subdir1 -subdir1 -subdir1 -subdir(n) -file1 -file1 -file2 -file(n) -file2 -file(n) Is there a simple script (preferably in bash, nothing fancy) that can accomplish the deletion of the extraneous files/folders in the event a file is renamed or moved to a different subdir? Is there a different program, much like rsync that can accomplish this task autonomously and in a much simpler manner? I have looked at unison, but I did not like the fact that it keeps a local database for the syncing info. Any tips at all as to how I am supposed to tackle this? Thank you in advanced for your help. EDIT: I have tried unison just recently and I can safely say it is out of the question now. unison is a bi-directional synchronization tool and from my testing, it mirrors the files existing on the server to all workstations. - This is unwanted. preferably, i would want files/folders to stay within their respective workstations and just merge to the server. AKA uni-directional sync; but with renames/moves propagated to the server. I might have to look into Git/Mercurial/Bazaar as mentioned by kyle, but still unsure if they are fit for the job.

• Re-configure Office 2007 installation unattended: Advertised components --> Local

  - by abstrask

  On our Citrix farm, I just found out that some sub-components are "Installed on 1st Use" (Advertised), which does play well on terminal servers. Not only that, but you also get a rather non-descriptive error message, when a document tried to use a component, which is "Installed on 1st Use" (described on Plan to deploy Office 2010 in a Remote Desktop Services environment): Microsoft Office cannot run this add-in. An error occurred and this feature is no longer functioning correctly. Please contact your system administrator. I have ~50 Citrix servers where I need to change the installation state of all Advertised components to Local, so I created an XML file like this: <?xml version="1.0" encoding="utf-8"?> <Configuration Product="ProPlus"> <Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" /> <Logging Type="standard" Path="C:\InstallLogs" Template="MS Office 2007 Install on 1st Use(*).log" /> <Option Id="AccessWizards" State="Local" /> <Option Id="DeveloperWizards" State="Local" /> <Setting Id="Reboot" Value="NEVER" /> </Configuration> I run it with a command like this (using the appropriate paths): "[..]\setup.exe" /config ProPlus /config "[..]\Install1stUse-to-Forced.xml" According to the log file, the syntax appears to be accepted and the config file parsed: Parsing command line. Config XML file specified: [..]\Install1stUse-to-Forced.xml Modify requested for product: PROPLUS Parsing config.xml at: [..]\Install1stUse-to-Forced.xml Preferred product specified in config.xml to be: PROPLUS But the "Final Option Tree" still reads: Final Option Tree: AlwaysInstalled:local Gimme_OnDemandData:local ProductFiles:local VSCommonPIAHidden:local dummy_MSCOMCTL_PIA:local dummy_Office_PIA:local ACCESSFiles:local ... AccessWizards:advertised DeveloperWizards:advertised ... And the components remain "Advertised". Just to see if the installation state is overridden in another XML file, I ran: findstr /l /s /i "AccessWizards" *.xml Against both my installation source and "%ProgramFiles%\Common Files\Microsoft Shared\OFFICE12\Office Setup Controller", but just found DefaultState to be "Local". What am I doing wrong? Thanks!

• Virtualmin & git integration

  - by weby3456

  I've installed virtualmin on my VPS to manage my websites. It's working perfect and as expected nearly a year now. Recently I wanted to add some features to one of my sites, and I need git integration. I've correctly installed git & gitweb on my server, and I can create repositories and watch them under http://sub.domain.com/git/gitweb.cgi Here is the current relevant directory tree: /home/user/domains/sub.domain.com/public_html/git/ drwxr-sr-x user user . drwxr-x--- user user .. -rw-r--r-- user user git-favicon.png -rw-r--r-- user user git-logo.png -rwxr-xr-x user user gitweb.cgi -rw-r--r-- user user gitweb.css drwxrwx--- apache user reponame.git /home/user/domains/sub.domain.com/public_html/git/reponame.git/ drwxrwx--- apache user . drwxr-sr-x user user .. drwxrwx--- apache user branches -rwxrwx--- apache user config -rwxrwx--- user user description -rwxrwx--- apache user HEAD drwxrwx--- apache user hooks drwxrwx--- apache user info drwxrwx--- apache user objects drwxrwx--- apache user refs But I have some questions: When I'm visiting http://sub.domain.com/git/gitweb.cgi, the owner is listed as 'Apache'. why? how can I change that? Usually, to create a new git repository, I'll do something like: $ mkdir proj $ cd proj $ git init Initialized empty Git repository in /home/user/proj/.git/ // here I'm creating the files or copy them from somewhere else $ git add *.php $ git add README $ git commit -m 'initial version' But after creating the repository in virtualmin, I can find a new dir named 'reponame.git' but not the '.git' dir. When I'm trying to run any git command (e.g. git status) I'm receiving "fatal: This operation must be run in a work tree". How can I work with that repository? Currently I need to explicitly grant access for users to be able to view the repositories via gitweb. How can I make certain repositories public?

• Setting up Mako with Cherrypy on nginx through FastCGI

  - by xuniluser

  I'm trying to use TemplateLookup from Mako, but can't seem to get it to work. Layout of the test site is: /var/www main.py templates/ index.html Nginx's config is setup as: location / { fastcgi_pass 127.0.0.1:8080; fastcgi_param SERVER_NAME $server_name; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param QUERY_STRING $query_string; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_pass_header Authorization; fastcgi_intercept_errors off; } Cherrypy's config has: [global] server.socket_port = 8080 server.thread_pool = 10 engine.autoreload_on = False tools.sessions.on = True A simple cherrypy setup in main.py seems to work fine. import cherrypy class Main: @cherrypy.expose def index(self): return 'Hello' cherrypy.tree.mount(Main(), '/', config='config') Now, if I modify this to use Mako's template lookup, I get a 500 error. I know it has something to do with serving static files, but I've tried over a dozen different configurations accoring to the cherrypy wiki, but none of them work. Here's a bare setup I have for the templates: import cherrypy from mako.template import Template from mako.lookup import TemplateLookup templates = TemplateLookup(directories=['templates'], output_encoding='utf-8') class Main: @cherrypy.expose def index(self): return templates.get_template('index.html').render(msg='hello') cherrypy.tree.mount(Main(), '/', config='config') Does anyone know how I can get this to work ?

  Hi people, I have this issue about orphan IBM JVM process being created in the process tree: For example: C:\Program Files\IBM\WebSphere\AppServer\bin>wsadmin -lang jython -f "C:\Hello.py" Hello.py has the simple implementation: import time i = 0 while (1): i = i + 1 print "Hello World " + str(i) time.sleep(3.0) My machine has such JVM information: C:\Program Files\WebSphere\java\bin>java -verbose:sizes -version -Xmca32K RAM class segment increment -Xmco128K ROM class segment increment -Xmns0K initial new space size -Xmnx0K maximum new space size -Xms4M initial memory size -Xmos4M initial old space size -Xmox1624995K maximum old space size -Xmx1624995K memory maximum -Xmr16K remembered set size -Xlp4K large page size available large page sizes: 4K 4M -Xmso256K operating system thread stack size -Xiss2K java thread stack initial size -Xssi16K java thread stack increment -Xss256K java thread stack maximum size java version "1.6.0" Java(TM) SE Runtime Environment (build pwi3260sr6ifix-20091015_01(SR6+152211+155930+156106)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows Server 2003 x86-32 jvmwi3260sr6-20091001_43491 (JIT enabled, AOT enabled) J9VM - 20091001_043491 JIT - r9_20090902_1330ifx1 GC - 20090817_AA) JCL - 20091006_01 While the program is running, I tried to kill it and subsequently I found an orphan IBM JVM process in the process tree. Is there a way to fix this issue? Why is there an orphan process in the first place? Is there something wrong with my code? I really don't believe that my simplistic code is wrongly implemented. Any suggestions?

• How does one open multiple tabs in TextWrangler?

  - by Closure Cowboy

  No, I'm not bluffing. I really can't figure this out. The setup: I went to File -> Open, and then selected a directory rather than a file. As expected, a directory tree opened on the left side of my document. Hooray! I can easily view the files' structure in my Rails project. So, I make a few changes in a file, and then I click on a different file in the directory tree. My problem: TextWrangler then asks me whether I want to save my changes. Huh? I say "No", and the new document doesn't open at all. Great. I try hitting Command+N (new document). A new window opens. Ughhhh. How the heck do I open documents in a new tab? Note: I have set the "New & opened documents" behavior to "Open in the front window". This does not change the behavior described (i.e. when a directory is opened rather than a single file).

• Why does this rsnapshot exclude not work?

  - by bstpierre

  Rsnapshot passes excludes directly to rsync, but rsync's behavior appears inconsistent. I've simplified my rsnapshot backup test to the following directory tree (this tree will be backed up): gorilla:~# find /tmp/snaptest -exec file {} \; /tmp/snaptest: directory /tmp/snaptest/SKIPTHIS: directory /tmp/snaptest/SKIPTHIS/xyz: directory /tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/snaptest/SKIPTHIS.txt: ASCII text My config file: config_version 1.2 snapshot_root /tmp/backup-media no_create_root 1 cmd_cp /bin/cp cmd_rm /bin/rm cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh cmd_logger /usr/bin/logger cmd_du /usr/bin/du interval hourly 6 interval daily 7 interval weekly 4 interval monthly 3 verbose 3 loglevel 3 logfile /media/maxtor-one-touch/rsnapshot.log lockfile /media/maxtor-one-touch/backups/.rsnapshot.pid rsync_short_args -a rsync_long_args --delete --numeric-ids --relative --delete-excluded exclude "SKIPTHIS/**" link_dest 1 backup /tmp/snaptest snaptest The result: gorilla:~# rsnapshot -c /tmp/snaptest.conf hourly echo 12638 > /media/maxtor-one-touch/backups/.rsnapshot.pid mkdir -m 0755 -p /tmp/backup-media/hourly.0/ /usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \ --exclude="SKIPTHIS/**" /tmp/snaptest \ /tmp/backup-media/hourly.0/snaptest touch /tmp/backup-media/hourly.0/ rm -f /media/maxtor-one-touch/backups/.rsnapshot.pid gorilla:~# find /tmp/backup-media/ -exec file {} \; /tmp/backup-media/: directory /tmp/backup-media/hourly.0: directory /tmp/backup-media/hourly.0/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp: sticky directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS.txt: ASCII text My confusion stems from the fact that if I copy-paste the rsync command echoed by rsnapshot, the SKIPTHIS directory is excluded! (I've tested with various other SKIPTHIS patterns with the same results.) Any idea what's going on?

• Why does redis report limit of 1024 files even after update to limits.conf?

  - by esilver

  I see this error at the top of my redis.log file: Current maximum open files is 1024. maxclients has been reduced to 4064 to compensate for low ulimit. I have followed these steps to the letter (and rebooted): Moreover, I see this when I run ulimit: ubuntu@ip-XX-XXX-XXX-XXX:~$ ulimit -n 65535 Is this error specious? If not, what other steps do I need to perform? I am running redis 2.8.13 (tip of the tree) on Ubuntu LTS 14.04.1 (again, tip of the tree). Here is the user info: ubuntu@ip-XX-XXX-XXX-XXX:~$ ps aux | grep redis root 1027 0.0 0.0 66328 2112 ? Ss 20:30 0:00 sudo -u ubuntu /usr/local/bin/redis-server /etc/redis/redis.conf ubuntu 1107 19.2 48.8 7629152 7531552 ? Sl 20:30 2:21 /usr/local/bin/redis-server *:6379 The server is therefore running as ubuntu. Here are my limits.conf file without comments: ubuntu@ip-XX-XXX-XXX-XXX:~$ cat /etc/security/limits.conf | sed '/^#/d;/^$/d' ubuntu soft nofile 65535 ubuntu hard nofile 65535 root soft nofile 65535 root hard nofile 65535 And here is the output of sysctl fs.file-max: ubuntu@ip-XX-XXX-XXX-XXX:~$ sysctl -a| grep fs.file-max sysctl: permission denied on key 'fs.protected_hardlinks' sysctl: permission denied on key 'fs.protected_symlinks' fs.file-max = 1528687 sysctl: permission denied on key 'kernel.cad_pid' sysctl: permission denied on key 'kernel.usermodehelper.bset' sysctl: permission denied on key 'kernel.usermodehelper.inheritable' sysctl: permission denied on key 'net.ipv4.tcp_fastopen_key' as sudo ubuntu@ip-10-102-154-226:~$ sudo sysctl -a| grep fs.file-max fs.file-max = 1528687 Also, I see this error at the top of the redis.log file, not sure if it's related. It makes sense that the ubuntu user isn't allowed to change max open files, but given the high ulimits I have tried to set he shouldn't need to: [1050] 23 Aug 21:00:43.572 # You requested maxclients of 10000 requiring at least 10032 max file descriptors. [1050] 23 Aug 21:00:43.572 # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.

• Knowledge and user generated content management system to track files, research, proposals, etc.?

  - by Eshwar

  I'll try keep it short. Here's the scenario: We have employees all over the world performing similar work i.e. research, generating powerpoint slides, word documents, graphics, etc. Many times a lot of this previous work can be reused for another future project. The current arrangement is email and phone calls which as you would agree is quick if you know where to look but otherwise archaic and very very inefficient. So I am looking for software that will allow me to do the following: Tag files e.g. an investor presentation on cellphone usage in kenya would be tagged investor, cellphone, kenya Manage references e.g. if we read something on the internet, should be able to paste that link in some fashion and tag it as above. Preferably cloud based so that it can be accessed by anybody and additionally would be nice (though NOT must) to have access levels (director, manager, everyone) A nice interface that non technically savvy folks can warm up to ;) A desktop app would be handy so that people don't always have to click upload or something A tree based system is inefficient in this case because content is usually linked across branches and also people might not quite agree on one format of a tree. Tagging works around this very nicely. What I have considered so far: Evernote (for its more professional look) Springpad (for its versatility with content) Mendeley (this is a research manager and in some ways ideal, but i fear its limited to PDFs) The goal is that when somebody wants to look for a document, they don't have to ask a colleague, they can just search with keywords and all relevant information shows up. Thanks!

• IIS 6 ASP.NET default handler-mappings and virtual directories

  - by Mark Lauter

  I'm having a problem with setting a default mapping in IIS 6. I want to secure *.HTML files with ASP.NET forms authentication. The problem seems to have something to do with using virtual directories to hold the html files. Here's how it's setup: sample directory tree c:/inetpub/ (nothing in here) d:/web_files/my_web_apps d:/web_files/my_web_apps/app1/ d:/web_files/my_web_apps/app2/ d:/web_files/my_web_apps/html_files/ app1 and app2 both access the same html_files directory, so html_files is set as a virtual directory in the web apps in IIS... sample web directory tree //app1/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) //app2/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) If I put a file called test.html in the root of //app1/ and then add the default mapping to the asp.net dll and setup my security on the root folder with deny="?", then accessing test.html works exactly as expected. If I'm not authenticated, it takes me to the login.aspx page, and if I am authenticated then it displays test.html. If I put the test.html file in the html_files directory I get a totally different behavior. Now the login.aspx page loads and I stuck some code in to check if I was still authenticated: <p>autheticated: <%=User.Identity.IsAuthenticated%></p> I figured it would say false because why else would it bother to load the login page? Nope, it says true - so it knows i'm authenticated, but it won't give me access to the test.html file. I've spent several hours on this and haven't been able to solve it. I'm going to spend some more time on google to see if I've missed something. Fingers crossed.

• Which isn't working on linode servers (Ubuntu 10.04)?

  - by chrisjlee

  Currently trying to configure a linode server running on ubuntu 10.04. I utilized a stackscript (Default drupal profile) which seemed to run successfully. The log indicate so as well. Then ssh'd into the server (as root) to try to configure php. When i run a which php, which php5 they both return nothing. A which python returns something though. I know where the default path to php but i usually just like to use it as confirmation that php exists. Do i have to modify some configurations to enable which to work? Also tab completion doesn't seem to work for when i apt-get install? Update: Thanks for the suggestions guys. I've ran a couple commands and no luck either: [ root@ ~ ] $ dpkg -l |grep php [ root@ ~ ] $ apt-get install php5-cli Reading package lists... Done Building dependency tree Reading state information... Done Package php5-cli is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5-cli has no installation candidate Then i tried installing php and php cli: [ root@ ~ ] $ sudo apt-get install php5 php5-cli sudo: unable to resolve host xxxxxxx Reading package lists... Done Building dependency tree Reading state information... Done Package php5 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5 has no installation candidate

• Why won't Media Monkey add one particular folder of mp3's?

  - by ChrisF

  I'm using the latest and greatest version on Media Monkey (free version) and it won't find the mp3's in one particular folder in my music tree. It can see all the other files in the tree and the folder shows up when I click Add/Rescan files to the library... I have full control over the folder and all the files in the folder. The files play in Windows Media Player. The files play in Media Monkey if I right click and play from the context menu. All the tracks are at least 2 minutes long and over 5MB long and Media Monkey is set to ignore files shorter than 20KB and include all files regardless of length. There was an issue in that the that the genre of the tracks was set to "Classical" and the option that allows you to browse the classical music independently of the other music isn't enabled in the free version. It's a Gold version option only. I hadn't spotted that my other classical music was also missing from the library (I have rather a large library). Once I retagged the music with a different tag and tried to add the files again it reported that it added the tracks, but they still didn't show up in the library.

• Outlook 2007 - Mailbox doesn't show my Items (like Calendar)

  - by cyntaxx

  Hi All, I have running an Exchange Server 2003 and 2 IBM Laptops (A&B)with XP SP3. On both Laptops Office 2007 is installed. Laptop "A" Outlook doesn't show me my Calendar and Notes entries in my mailbox tree on Laptop "A". I can click on the calenendar tab and the entries are there. On Laptop "B" it is working fine. I know that I can make a "rigth click" on "mailbox" and choose "create new folder". Than I select i.g. my calendar. It creates it, but I can't access it through my mailbox tree. Clicking on the Calendar tab works fine again. So, the mailbox is fine (I think). There must be failure with Outlook. I tried these commands here with no positive result. Outlook /cleanviews Outlook /resetfolders I want to avoid a repair installation of Outlook, because the whole office needs to be repaired. (And both laptops belong to my boss) :) Thanks, Toby
