• How can one one-handed ease working in Emacs?

  - by N.N.

  My right hand is temporarily immobilized. I would like to do some minor work in Emacs, mostly in Org-mode, but also some in AUCTeX. Is there some way to ease one-handed work in Emacs such as some mode or particular work flow? For instance I noticed pressing C-x u is easier than C-_ for undoing and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands. I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not what I am asking for. I want to ease whatever little time spent one-handed in Emacs and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I also do realize I should avoid unnecessary strain.

• Is it possible to use os.walk over SSH?

  - by LeoB

  I'm new to Python so forgive me if this is basic, I've searched but can't find an answer. I'm trying to convert a Perl script into Python (3.x) which connects to a remote server and copies the files in a given directory to the local machine. Integrity of the transfer is paramount and there are several steps built-in to ensure a complete and accurate transfer. The first step is to get a complete listing of the files to be passed to rsync. The Perl script has the following lines to accomplish this: @dir_list = `ssh user@host 'find $remote_dir -type f -exec /bin/dirname {} \\;'`; @file_list = `ssh user@host 'find $remote_dir -type f -exec /bin/basename {} \\;'`; The two lists are then joined to create $full_list. Rather than open two separate ssh instances I'd like to open one and use os.walk to get the information using: for remdirname, remdirnames, remfilesnames in os.walk(remotedir): for remfilename in remfilesnames: remfulllist.append(os.path.join(remdirname, remfilename)) Thank you for any help you can provide.

• Perl - Reading .txt files line-by-line and using compare function (printing non-matches only once)

  - by Kurt W

  I am really struggling and have spent about two full days on this banging my head against receiving the same result every time I run this perl script. I have a Perl script that connects to a vendor tool and stores data for ~26 different elements within @data. There is a foreach loop for @data that breaks the 26 elements into $e-{'element1'), $e-{'element2'), $e-{'element3'), $e-{'element4'), etc. etc. etc. I am also reading from the .txt files within a directory (line-by-line) and comparing the server names that exist within the text files with what exists in $e-{'element4'}. The Problem: Matches are working perfectly and only printing one line for each of the 26 elements when there is a match, however non-matches are producing one line for every entry within the .txt files (37 in all). So if there are 100 entries (each entry having 26 elements) stored within @data, then there are 100 x 37 entries being printed. So for every non-match in the: if ($e-{'element4'} eq '6' && $_ =~ /$e-{element7}/i) statement below, I am receiving a print out saying that there is not a match. 37 entries for the same identical 26 elements (because there are 37 total entries in all of the .txt files). The Goal: I need to print out only 1 line for each unique entry (a unique entry being $e-{element1} thru $e-{element26}). It is already printing one 1 line for matches, but it is printing out 37 entries when there is not a match. I need to treat matches and non-matches differently. Code: foreach my $e (@data) { # Open the .txt files stored within $basePath and use for comparison: opendir(DIRC, $basePath . "/") || die ("cannot open directory"); my @files=(readdir(DIRC)); my @MPG_assets = grep(/(.*?).txt/, @files); # Loop through each system name found and compare it with the data in SC for a match: foreach(@MPG_assets) { $filename = $_; open (MPGFILES, $basePath . "/" . $filename) || die "canot open the file"; while(<MPGFILES>) { if ($e->{'element4'} eq '6' && $_ =~ /$e->{'element7'}/i) { ## THIS SECTION WORKS PERFECTLY AND ONLY PRINTS MATCHES WHERE $_ ## (which contains the servernames (1 per line) in the .txt files) ## EQUALS $e->{'element7'}. print $e->{'element1'} . "\n"; print $e->{'element2'} . "\n"; print $e->{'element3'} . "\n"; print $e->{'element4'} . "\n"; print $e->{'element5'} . "\n"; # ... print $e->{'element26'} . "\n"; } else { ## **THIS SECTION DOES NOT WORK**. FOR EVERY NON-MATCH, THERE IS A ## LINE PRINTED WITH 26 IDENTICAL ELEMENTS BECAUSE ITS LOOPING THRU ## THE 37 LINES IN THE *.TXT FILES. print $e->{'element1'} . "\n"; print $e->{'element2'} . "\n"; print $e->{'element3'} . "\n"; print $e->{'element4'} . "\n"; print $e->{'element5'} . "\n"; # ... print $e->{'element26'} . "\n"; } # End of 'if ($e->{'element4'} eq..' statement } # End of while loop } # End of 'foreach(@MPG_assets)' } # End of 'foreach my $e (@data)' I think I need something to identical unique elements and define what fields make up a unique element but honestly I have tried everything I know. If you would be so kind to provide actual code fixes, that would be wonderful because I am headed to production with this script quite soon. Also. I am looking for code (ideally) that is very human-readable because I will need to document it so others can understand. Please let me know if you need additional information.

• How do you get the File:// protocol to work in IE8?

  - by chrismay

  I am running a website on my local machine ("http://localhost/asdf") and trying to get some file:// protocol links to work. In reality I'm trying to open a folder, not a specific file, but I can't get either to work. I've put localhost in my "trusted zone", I've tried every combo of "file" ,":", some number of "/" and then a whole bunch of different paths, but encoded and not encoded. Nothing I do causes anything to open when I click on the link. If I copy the link destination, and paste that in the browser address window, then it works as expected. Anyone know the secret?

• ftp-client works fine. ftp-tls-client fails on one computer and works on another

  - by ispiro

  Connecting to ftp - from a Windows Server 2012 - it works both secure (-over tls) and unsecure. From a Windows 7 it succeeds unsecure but fails when secure. (Using explicit TLS and passive mode.) filezilla: 234 AUTH command ok. Expecting TLS Negotiation. Initializing TLS... Connection timed out I've tried many things but nothing helps. (I'm also trying this programmatically. For details see: http://stackoverflow.com/questions/25393716/ftp-ssl-fails-after-expecting-tls-negotiation ) The fact that it does succeed from one computer proves that the ftp server is fine. And the fact that the Windows 7 computer succeeds without tls proves that it's not a NAT/firewall problem (besides, it failed even after disabling firewall etc.). I'm not sure where to start looking. Perhaps a difference between PC Windows and Windows Server? EDIT The ftp server is on a Windows Server 2012.

• How to call a Zend lucene search function?

  - by stef

  I inherited a Zend project devoid of comments and I didn't get to talk to the previous developer. Since I have no Zend experience I'm having some issues :) I'd like to print out some variables inside an function that indexes items from the site using Zend_Search_Lucene because I think something is going wrong here. From what I've read, ::create creates a new index and ::open updates it. So it's in this ::open function I'd like to print out some variables. The name and params of the function are below. Does anyone have any idea how this function can be called so I can run some tests? private function search($category,$string,$page = 1,$itemsByPage = 5) EDIT: OR, is there a way I can nuke the existing index and force it to be rebuilt completely, for example by deleting the index files on the FS and then performing some searches?

• Sharepoint managed Properties

  - by paulie

  Originally posted on StackOverflow, and edited for clarity I have a custom Content Type inside a list that has over 30 items (Which were uploaded via DockIt), and I have added several "managed properties" to the "crawled properties", in the SSP. All of them work except 1. The column "Synopsis" is a multiline field with no limit on it's length. It appears as a crawled property "Synopsis", and is mapped to a managed property 'asynop'. On the 'Advanced Search Page', it is added as a property and searchable, however it only returns a some matching records (if any). I manually created an entry, ran the crawl and was able to search for it. I edited an existing entry, ran the crawl (full and incremental), and it still only returned the manually entered entry. If I entered the search term in the Search box directly "asynop:fatigue", then all the correct results appear. Why is this happening? And could it please stop?

• Java: PriorityQueue returning incorrect ordering from custom comparator??

  - by Michael Simpson

  I've written a custom comparator to compare my node classes, but the java priority queue is not returning my items in the correct order. Here is my comparator: public int compare(Node n1, Node n2){ if (n1.getF() > n2.getF()){ return +1; } else if (n1.getF() < n2.getF()){ return -1; } else { // equal return 0; } } Where getF returns a double. However after inserting several Nodes into the priority queue, I print them out using: while(open.size() > 0) { Node t = (Node)(open.remove()); System.out.println(t.getF()); } Which results in: 6.830951894845301 6.830951894845301 6.0 6.0 5.242640687119285 7.4031242374328485 7.4031242374328485 8.071067811865476 Any ideas why this is so? Is my comparator wrong? Thanks. Mike

• Writing a unique identifier to script?

  - by dannycab

  I'd like to write a subscript that adds a unique identifier (machine time) to a script everytime that it runs. However, each time I edit the script (in IDLE) the indetifiers are over-written. Is there a elegant way of doing this. The script that I wrote appears below. import os, time f = open('sys_time_append.py','r') lines = f.readlines() f.close() fout = open('sys_time_append.py','w') for thisline in lines: fout.write(thisline) fout.write('\n#'+str(time.time())+' s r\n') fout.close() Thanks for any help.

• Is there a way to undo deletion of registry keys while the machine is still running?

  - by Oliver Giesen

  [ also posted from a programmer's POV at http://stackoverflow.com/questions/3299230 ] I messed up big time and deleted a large portion of my registry during a programming experiment: As a result most of the contents of HKEY_CURRENT_USER\Software\ are gone. I haven't logged off or shutdown since this happened. The applications that were already running seem to be coping fine so far but I suspect that after the next reboot there won't be much happiness left... Also, System Restore tells me there are no restore points even though I'm pretty sure there should have been. Could this be another symptom of the purged registry? I wouldn't have expected this information to be stored under HKCU, though... Does anybody know of a technique or utility that can possibly restore some or all of the deleted entries? I'm on Windows 7 Enterprise 32bit. I'm not really holding my breath but you can always hope, can't you?

• htaccess with wildcard SSL

  - by Ericko

  We have a Wildcard SSL Certificate that is supposed to work on any subdomain of a given domain. So in this server we have this file structure: /home/DOMAIN/public_html/subdomainx /home/DOMAIN/public_html/subdomainy etc... Now, the Certificate is installed, but when you visit any subdomain over https (example: hxxps://subdomainx.domain.com ) it points to /home/DOMAIN/public_html/index.php We need that when you visit a subdomain via https hxxps://subdomainx.domain.com That it points to the the same directory that it's http equivalent: /home/DOMAIN/public_html/subdomainx Our provider tells us that this is not possible, that the current behaviour is correct, and that to achieve this we need to do it with htaccess. I've tried a few things, incluiding this solution, that seems to be what I need: http://stackoverflow.com/questions/5365612/advice-on-configuring-htaccess-file-to-redirect-http-subdomain-to-https-equival But can't get it to work. Any tips? Thanks. Added: The server is Apache.

• How do I effectively write to 146 output files in C++ using cstdlib library

  - by Elpezmuerto

  I have a very large binary file and I need to create separate files based on the id within the input file. There are 146 output files and I am using cstdlib and fopen and fwrite. FOPEN_MAX is 20, so I can't keep all 146 output files open at the same time. I also want to minimize the number of times I open and close an output file. How can I write to the output files effectively? I also must use the cstdlib library due to legacy code.

• What is the universal way to use file I/O API with unicode filenames?

  - by dma_k

  In Windows there is a common problem: the filenames should be converted to local codepage, before they are passed to open(). Of course, there is a possibility to use Win32::API for that, but I don't want my script to be platform-dependent. At the moment I have to write something like: open IN, "<", encode("cp1251", $filename) or die $!; but is there any library, that hides these details? I think the local codepage can be automatically detected, so I just want to pass unicode filename and forget about the details. Why is it still not in the box?

• Is Joerg Schilling’s “sdd” a full replacement for “dd”

  - by fishtoprecords

  I was directed to post here, I started on Stackoverflow.... I'm trying to use 'sdd' on my Debian system, and can't get one set of options to work. They do work in 'dd' so I am wondering if I am specifying them incorrectly, or if sdd didn't implement them, or something else. What I want to do is sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 conv=sync,noerror if I leave out the "conv=..." option, it works, or at least starts copying data. sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 Can you shed a bit of light?

• Which is the best design practice for edit data in RIA?

  - by Onet Two

  Hi, First of all it is a UI design question! Which is the best design practice for edit data in RIA, for example in Flex or Silverlight? I would like to show customer's details, but there will be an edit window, than the datas of customer will be editable. I would like to show a new form where the data can be edited. What is the simplest way to show this form. I can make my ui tabbed, so I can open the form in a new tab, or I can open the form in a popup/modal dialog (Save-cancel). Maybe I can use in line editing. What is the most user friendly solution in a Silverlight or Flex GUI? What is your opinion? Thanks!

• Hook to make Subversion Read Only for specific users

  - by Shane

  We have an existing Subversion repository that uses LDAP to manage users/passwords. There are some new users who we would like to provide read-only access to SVN. I did some Google searches and found a way to open up read-only access to anonymous users, but this is not what we want. We do not want to open up SVN to everyone. We still want to control login through LDAP, but we would like to prevent certain named users from being able to add/edit/delete. I am assuming this can be done with a hook (pre-commit?), but I have no experience writing hooks. Can someone show me or point me to an example of how to do this?

• PHP Sockets Errors (connection refused and No such file or directory)

  - by Purefan

  Hello all, I am writing a server app (broadcaster) and a client (relayer). Several relayers can connect to the broadcaster at the same time, send information and the broadcaster will redirect the message to a matching relayer (for example relayer1 sends to broadcaster who sends to relayer43, relayer2 - broadcaster - relayer73...) The server part is working as I have tested it with a telnet client and although its at this point only an echo server it works. Both relayer and broadcaster sit on the same server so I am using AF_UNIX sockets, both files are in different folders though. I have tried two approaches for the relayer and both have failed, the first one is using socket_create: public function __construct() { // where is the socket server? $this->_sHost = 'tcp://127.0.0.1'; $this->_iPort = 11225; // open a client connection $this->_hSocket = socket_create(AF_UNIX, SOCK_STREAM, 0); echo 'Attempting to connect to '.$this->_sHost.' on port '.$this->_iPort .'...'; $result = socket_connect($this->_hSocket, $this->_sHost, $this->_iPort); if ($result === false) { echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($this->_hSocket)) . "\n"; } else { echo "OK.\n"; } This returns "Warning: socket_connect(): unable to connect [2]: No such file or directory in relayer.class.php on line 27" and (its running from command line) it often also returns a segmentation fault. The second approach is using pfsockopen: public function __construct() { // where is the socket server? $this->_sHost = 'tcp://127.0.0.1'; $this->_iPort = 11225; // open a client connection $fp = pfsockopen ($this->_sHost, $this->_iPort, $errno, $errstr); if (!$fp) { $result = "Error: could not open socket connection"; } else { // get the welcome message fgets ($fp, 1024); // write the user string to the socket fputs ($fp, 'Message ' . __LINE__); // get the result $result .= fgets ($fp, 1024); // close the connection fputs ($fp, "END"); fclose ($fp); // trim the result and remove the starting ? $result = trim($result); $result = substr($result, 2); // now print it to the browser } which only returns the error "Warning: pfsockopen(): unable to connect to tcp://127.0.0.1:11225 (Connection refused) in relayer.class.php on line 33 " In all tests I have tried with different host names, 127.0.0.1, localhost, tcp://127.0.0.1, 192.168.0.199, tcp://192.168.0.199, none of it has worked.

• How to get a list of users for all instance's databases

  I guess the procedure should be something like this: declare @db varchar(100) declare @user varchar(100) declare c cursor for select name from sys.sysdatabases open c fetch next from c into @db while @@fetch_status = 0 begin print @db exec ('use ' + @db) declare u cursor for select name from sys.sysusers where issqlrole <> 1 and hasdbaccess <> 0 and isntname <> 1 open u fetch next from u into @user while @@fetch_status = 0 begin print @user fetch next from u into @user end print '--------------------------------------------------' close u deallocate u fetch next from c into @db end close c deallocate c But the problem is that exec ('use ' + @db) doesn't work. And i always get user list of currently chosen database. How should i fix that? P.S.: I want this code to work on both 2000 and 2005 sql servers.
