• $RYSNC_PASSWORD not being read/responded-to correctly (Snow Leopard)

  - by warren

  Ignoring the security issues, I have the following script that synchronizes my music library from my MacBook Pro (running Snow Leopard) to the file store (CentOS 4) on my network: rsync -rav --progress --partial -e "ssh" ~/Music/iTunes/* user@scramasax:~/music/iTunes-scissor:~ When I try to use either a password provided on the command-line (), in a password file (--password-file), or in the environment variable RSYNC_PASSWORD, the login still goes interactive, requiring me to type my password again. I will be moving to pre-shared keys on my network, but in situations where that is not possible, such as rsync'ing files to a webserver, being able to successfully embed the password in the script would be very helpful.

• nginx php-fpm uploaded files have nginx ownership after executing move uploaded file

  - by Vangel

  I have a problem with php 5.3.6 using PHP-FPM and file uploads. My Nginx runs as user nginx PHP-FPM uses pools configured for each vhost. For example a user: test group : test runs one pool. When the php file uploads to temp file it is owned by user test. After move_uploaded_file is executed by php script it is owned by nginx :/. The reason for this could be the fact that the original upload file script does an exec('/usr/bin/php do_uploadedfiles.php') which does the actual moving. I do not know if the change in ownership to web server is the correct behaviour. Is there a way in PHP to change the ownership back to the user I want? Maybe make exec "run as"?

• HDD Carrier, like a soda carrier available at McDonalds?

  - by Jason Taylor

  We use external USB drives for backups, and they have to be stored offsite at the end of the week. Right now we have your standard external USB drive inside an enclosure. We were thinking about moving to a USB dock, and dock a bare HDD for backups, rather than having various sized and types of enclosures. If we were to do this, the drives need protection while being transported to/from the safety deposit box. Is there any kind of hard drive carrier that would let us slide two drives into it, and it would provide protection while the drives are carried around by non-technical people? I'm afraid such a product doesn't exist, but perhaps someone knows of something?

• binary search and trio

  - by user121196

  given a large list of alphabetically sorted words in a file,I need to write a program that, given a word x, determines if x is in the list. priorties: 1. speed. 2. memory I already know I can use (n is number of words, m is average length of the words) 1. a tri, time is O(log(n)), space(best case) is O(log(n*m)), space(worst case) is O(n*m). 2. load the complete list into memory, then binary search, time is O(log(n)), space is O(n*m) I'm not sure about the complexity on tri, please correct me if they are wrong. Also are there other good approaches?

• How to change drag & drop behaviour in Windows 7's explorer?

  - by Pekka

  I have a new touch screen, and am playing around with its functionality. The most productive use for me is organizing files (literally) by hand. It's fun working through a list of files, dragging and dropping them to the right locations using your index finger. It feels better on the wrist than mouse-clicking, too. The only problem is that when I drag & drop files across drives in Windows 7, the default behaviour is to copy the file instead of moving it. I know I can influence this using right click, but that is of course no option in my situation. How can I change the default drag & drop behaviour in Windows 7's explorer?

• Google Drive have a folder/file in both private and public

  - by Sander

  I've my documents in Google Drive/Docs neatly organised in structured folder system. For not cluttering email inboxes purposes I now would like to share the content of 1 single private folder by putting it in the public directory. If possible I'd like to do this without duplicating the content. Is it possible to organise files in Google Drive to that they have 2 tags/folders attached to them - 1 private and 1 public? Is there another way to quickly share/link a folder to my public folder without actually moving it away from my private to my public folder?

• Making Lync option visible in Outlook/GAL/AD

  - by Kjensen

  In a big organization, people are slowly moving towards using Lync and away from using landlines. A handful of times per month, I get a meeting invitation that includes a conference call number and a remark about "not sure if everybody is on Lync". Often everybody is, and we start in a conference call and switch to Lync. Is there a good way to make it visible if a user has access to Lync? Like I can hit the "Online meeting" button in Outlook - and it would be great to see, if everybody invited support Lync. Does something like that exist?

• importing content into drupal.

  - by anru

  I have a wordpress site with 5k post and each post has average 25 comments. so 125k total nodes have to be added. I need import those posts and comments into drupal 6 . I have written a script to import those post/comments into drupal by drupal's cron service. but the cron service keeps time out. because import 125k nodes one by one is very slow. what can i do to imporve drupal importing speed? i am use drupal built in node_save(), comment_save() method to do it. I have not find out a way to use customized SQL query to increase importing speed yet. I am execute my script through drupals's cron.php, that mean even i have set 'max_execute_time' to unlimited, but that only affects PHP , apache server has it own time out setting.

• Windows hangs on Rename, Delete and Move for specific MKV files

  - by Creativehavoc

  I have been googling this issue for a long time, and no full solutions seem to be out there. For certain mkv files, windows hangs when moving, copying, or deleting. These files play fine in a player such as GOM player. System: a fast windows 7, 64 bit box. Results: CPU change is negligible Memory usage rockets up to ~100% In cased of delete or move, "discovering files" dialogue box stays up for a long time Rename simply shows spinning icon until it finishes Action is completed after EXTREMELY long amount of time Memory usage does not return to normal "Fixes:" Disable thumbnail creation (helps for some cases) After move/rename/delete kill explorer with taskmanager, and relaunch to re-claim your memory Even with the thumbnails turned off, the issue persists. I have also tried re-muxing a file, which worked fine, but still resulted in a file with the same above issues.

• Site to site VPN using RRAS from an untrusted network?

  - by DrZaiusApeLord

  Our remote office will be moving to a new space where internet will be provided. They'll be behind a router doing NAT (I do not have admin rights to this router). They will be sharing a printer with the other people on the LAN, but will need VPN to our network for email and file shares. I was thinking of just having them run the windows VPN client and connecting via PPTP like they do when they are off-site, but I have read that multiple PPTP connections from the same NAT'd address to the same destination doesn't work well or at all. I am thinking some kind of site-to-site VPN is needed so there is just one tunnel. Can I just put in a VPN gateway, set it to connect to our RRAS/PPTP server, and have them use it as their default gateway? Perhaps even use the local default gateway for internet traffic. If so, what VPN gateway/device is recommended for this? Or other solutions? Thanks.

• Domain and TS migration

  - by Windex

  The migration steps outlined by Microsoft in the ts migration seem to deal with moving TS to a different server on the same domain and call for adding the licensing service to another system, move the licenses and then put TS on whatever server you want. However with migrating the domain as well I don't have any place to move the TS server to. So my thought was to simply re-activate my licenses on the new server using the same method as a new TS setup. My question is essentially will this work the way I think it will or will the MS activation clearing house deny the new server? Is there a procedure to follow that "deactivates" the licenses on a server so that the clearing house knows there are some free? (FWIW I can look up the license information through the eopen website and have access to the original license doc.)

• When is performance gain significant enough to implement that optimization?

  - by Zwei steinen

  Hi, following the text book, I do measure performance whenever I try optimizing my code. Sometimes, however, the performance gain is rather small and I can't decisively decide whether I should implement that optimization. For example, when a fix shortens an average response time of 100ms to 90ms under some conditions, should I implement that fix? What if it shortens 200ms to 190ms? How many condition should I try before I can conclude that it will be beneficial overall? I guess it's not possible to give a straight forward answer to this, as it depends on too many things, but is there a good rule of thumb that I should follow? Are there any guideline/best-practices?

• Opening password protected Excel 2007 documents by double clicking from My documents does not work u

  - by erik-van-gorp

  When all of the following conditions are true, excel will open (most of the time) but will not open the document itself. No error is displayed. This only occurs with Excel files, Word and powerpoint do open perfectly. Conditions : OS is "Windows 7 Professional 64-bit" office is "Office 2007 Ultimate". excel file is in .xls (2003 format) excel file is password protected excel file is in "My Documents" (or a subfolder of it) file is double-clicked from explorer under Windows 7. Following options do open the excel file as it should : right click and selecting the (bold) open action single click the file and pressing enter moving the file to the desktop and double-click it. non password protected files do open from the same directory. Actions taken not resolving the problem: - reboot - repair office installation - system restore does not work because of Antivirus application installed (message from system restore, using "Symantec Internet Security 2010") Anyone any idea ?

• Going from dev to sysadmin advice [on hold]

  - by dotnetdev

  I've seen the threads on here about transitions to/from sysadmin. My story is I am a dev (technology is irrelevant), but in learning that technology it required a lot of server infrastructure. In the last few years, I thus had to setup a lot of infrastructure (AD, DNS, SQL etc) to learn said technology. I've noticed that I've enjoyed doing sysadmin and got quite good at it, and find it even engrossing (e.g. I am amazed by how decievingly complicated AD is, under the hood). I'm now thinking of moving into IT infrastructure after about 4 years in various dev (.NET) roles. Any advice? My concern is that I don't have any experience with hardware load balancers and firewalls like F5 etc, which some jobs require. How could I compensate for that? Also, I'm rubbish with my hands, would this be a factor? (i.e. maintaining physical kit)? Thanks

• Computationally simple Pseudo-Gaussian Distribution with varying mean and standard deviation?

  - by mstksg

  This picture from wikipedia has a nice example of the sort of functions I'd ideally like to generate http://en.wikipedia.org/wiki/File:Normal_Distribution_PDF.svg Right now I'm using the Irwin-Hall Distribution, which is more or less a Polynomial approximation of the Gaussian distribution...basically, you use uniform random number generator and iterate it x times, and take the average. The more iterations, the more like a Gaussian Distribution it is. It's pretty nice; however I'd like to be able to have one where I can vary the mean. For example, let's say I wanted a number between the range 0 and 10, but around 7. Like, the mean (if I repeated this function multiple times) would turn out to be 7, but the actual range is 0-10. Is there one I should look up, or should I work on doing some fancy maths with standard Gaussian Distributions?

• What is a programmer's life like?

  - by Zee JollyRoger

  Imagine like an 8-hour long video of any "typical/average" programming job. What is it like? Before I get myself involved in that path, what can I expect? I am interested in gathering first-hand information and accounts of the typical life of a programmer. My goal is to grasp the fundamental concepts of working in the professional field of programming. I just want to "see" into what it is/means to come to an entry-level programming job and program. See what kind of skills, mentality, expectations, and such are required.

• How to get old DLL's running on 64bit server

  - by quakkels

  Hello all, I'm moving my company's websites from a windows 2003x86 server to windows 2008x64 which is running IIS 7.5. The problem that I've got is that all the DLL's which were running fine on the old server, now error out whenever they're called. All I get is a generic error like: Server object error 'ASP 0177 : 800401f3' Server.CreateObject Failed /folder/scriptname.asp, line 24 800401f3 The line that errors is: '23 lines of comments set A0SQL_DATA = server.createobject("olddllname.Data") 'the rest of the script I already have that site running in an App Pool that is set to 32bit mode. But, I get the error anyway. Has anyone experienced this? I'm frusterated because all the info I look up says that all I need to do is set the app pool to run in 32bit mode. I did that and It's still not working. What else could I check?

• CPU spikes on small site- possibly apache or php config related

  - by Mike

  Hello, I hope you can help me. I have a site that I'm moving to a new datacenter. The server is pretty much vanilla, no control panel, and also no optimizations. When I hit a page, the site takes an extremely long time to load, despite it being relatively light weight. I ran top to see what was happening, and the cpu jumps to 75%, and drops back down to about 20% while the rest of the page is loading. Someone suggested that I ran lsof -p on the offending processes, but I'm not sure what I'm looking at. I ran through my httpd.conf file and commented out a bunch of loaded modules that didn't seem necessary, but that didn't help either. Anyone have any ideas? Output of the lsof http://pastebin.com/mfa113f

• How do you find out release, mailing list statistics information on open source projects

  - by Samuel

  We are interested in finding out some statistics of various frameworks Mailing list activity on say richfaces. Much similar to what is available on http://code.google.com (Low, Medium, High) + average number of emails per day | per month. Number of releases made in a year including patch, minor, major releases. We did look at the maven repositories but that wasn't very useful either. We did look at ohloh, but didn't get the desired information. Any other ideas on where to get this information (any maven-2 plugins)?

• How to calculate order (big O) for more complex algorithms (ie quicksort)

  - by bangoker

  I know there are quite a bunch of questions about big O notation, I have already checked Plain english explanation of Big O , Big O, how do you calculate/approximate it?, and Big O Notation Homework--Code Fragment Algorithm Analysis?, to name a few. I know by "intuition" how to calculate it for n, n^2, n! and so, however I am completely lost on how to calculate it for algorithms that are log n , n log n, n log log n and so. What I mean is, I know that Quick Sort is n log n (on average).. but, why? Same thing for merge/comb, etc. Could anybody explain me in a not to math-y way how do you calculate this? The main reason is that Im about to have a big interview and I'm pretty sure they'll ask for this kind of stuff. I have researched for a few days now, and everybody seem to have either an explanation of why bubble sort is n^2 or the (for me) unreadable explanation a la wikipedia Thanks!

• Adding operation in middle of complex sequence diagram in visio 2003

  - by James

  I am using Microsoft Visio 2003 to define static classes with operations/methods and a sequence diagrams referring to these classes. The sequence diagram is almost done, but i realized that i missed one operation in middle of the diagram. When i try to move rest of the sequences down by selecting it as a block, all the operations in the block loose link with static diagrams. ( Methods which were referred to static classes as fun(), became fun, which means that now they no longer refer to static diagrams and any future changes would not be reflected in dynamic sequence diagrams automatically.) The sequence diagrams have grown to A3 size paper and i have many of such diagrams which needs correction. Manually moving the operations one by one would involve lots of effort. Could someone kindly suggest a way to overcome this problem?

• Ubuntu 9.1 Only Sees 244 MB RAM, while BIOS and Windows Sees 1.5 GB

  - by nicorellius

  I have 1.5 GB of RAM installed on an older Dell, Pentium 4. I just installed Ubuntu 9.1 and the system is only seeing 244 MB of RAM, even though there is 1.5 GB on the system. The BIOS sees all of it. I ran a Knoppix disc and it only saw 25 MB upon booting. I made no particular changes to the installation taht would affect this. I looked through the BIOS and the only setting I could see was the AGP aperture. Not even sure what this is. Anyone know where I went wrong? I also tried moving the memory modules around on the board. Booted with the 1 GB stick, still saw 244 MB.

• USB flash drive unreadable after a few minutes on Windows 8

  - by B Sharp

  I recently got a new computer with Windows 8. I a have a number of large backup files I am moving from my old PC to my new one. I was able to successfully copy the files to a couple 16 GB flash drives. When I try to copy the files to my new computer, the process starts just fine but after copying about 4 GB of files, the copy stops. If I look at the drive in explorer, the drive is there, but I just get a busy cursor that stays indefinitely if I click it. If I unplug the flash drive and plug it back in, everything is fine again... for a couple minutes. I've tried copying from both flash drives with the same result. I've also tested this on the USB 2.0 and 3.0 ports on my motherboard with the same result (the drives are USB 2.0) It's also puzzling that this is happening since I previously used one of the same flash drives to install Windows 8 on this computer in the first place without any difficulty.

• buggy mouse click after a while

  - by sputnick

  The cursor of my mouse is moving as well on my twin view, but after a WHILE, or if I start kde with runlevels (I don't know why, but startx works better) I can't click anything. I have had replaced the mouse with another one, but it's the same problem, so it's not a hardware problem. The problem occurs both with gnome and kde. My config : PC Dell Optiplex 780 archlinux x86_64 (up to date) xf86-input-evdev 2.6.0-4 xorg-server 1.11.2-2 kernel linux-3.1.1-1-ARCH My Xorg log doesn't contains "EE" string for errors. Any clue ?
