• Sane patch schedule for Windows 2003 cluster

  - by sixlettervariables

  We've got a cluster of 75 Win2k3 nodes at work in a coarse grained compute cluster. The cluster is behind a mountain of firewalls and resides in its own VLAN. Jobs of all sizes and types run on the cluster and all of the executables running are custom-made. (ed: additional notes on our executables) The jobs range from 30 seconds to 7 days in duration, and may contain one executable or 2000 sub-jobs (of short duration). Obviously we are trying to avoid the situation where our IT schedules a reboot during a 7 day production job. We have scheduling software which accomodates all of the normal tasks for a coarse grained cluster and we can control which machines are active for submission, etc. If WSUS was in some way scriptable (or the client could state it's availability for shutdown) we could coordinate the two systems and help out. Currently, the patch schedule is the Sunday after Super Tuesday regardless of what is running on the cluster. We have to ask for an exemption every time we want to delay patching a machine for a long running production job. Basically, while our group is responsible for the machines we have little control over IT's patch schedule. Is patching monthly with MS's schedule sane for a production Windows cluster? Are there software hooks in WSUS where we could say, "please don't reboot just yet"?

• How do I fix error 1303 during TI Connect install?

  - by smoth190

  I recently purchased a TI-84 Plus graphing calculator, and I'm trying install the TI Connect software in order to connect the calculator to my computer via the USB cable. Unfortunately, I'm getting this error while trying to install the program: Error 1303. The installation has insufficient privileges to access this directory: E:\Data\Timothy\Documents\MyTIData. The installation cannot continue. Log on as administrator or contact your system administrator. However, my account is the only account on my PC, and it has administrative privileges. I've also tried running the installer with Run as Administrator, but with no luck. If I create the folder MyTIData manually, I receive this error: Error 1317. An error occurred while attempting to create the directory: E:\Data\Timothy\Documents\MyTIData I've reapplied the security settings to the E:\Data folder (and all its sub-directories) to Full for my account. I've also gone into Computer Management, and given SYSTEM full privileges for the entire disk. I've also logged out, logged back in, restarted, etc. but still, no luck. Now, I should mention that my Documents folder is not at the default location. I changed it due to my C: disk being a 90GB SSD, so I moved all my personal data onto the extra storage disk (which is ~1TB). I don't know if that is causing the issue, but it can't hurt throwing it out there. So why can't I install this program? Google'ing the problem brings up this error for various other installers (such as Visual Studio and Microsoft Office), but nothing for TI Connect. All the solutions are the same: Give the folder Full privileges...but I've already done this! I've also tried running the installer with and without the calculator plugged in, but it didn't change anything. In the prompt that contains the error, repeatedly clicking Retry or waiting a few moments before clicking Retry also produces no result.

• SQL Server Read Locking behavior

  - by Charles Bretana

  When SQL Server Books online says that "Shared (S) locks on a resource are released as soon as the read operation completes, unless the transaction isolation level is set to repeatable read or higher, or a locking hint is used to retain the shared (S) locks for the duration of the transaction." Assuming we're talking about a row-level lock, with no explicit transaction, at default isolation level (Read Committed), what does "read operation" refer to? The reading of a single row of data? The reading of a single 8k IO Page ? or until the the complete Select statement in which the lock was created has finished executing, no matter how many other rows are involved? NOTE: The reason I need to know this is we have a several second read-only select statement generated by a data layer web service, which creates page-level shared read locks, generating a deadlock due to conflicting with row-level exclusive update locks from a replication prcoess that keeps the server updated. The select statement is fairly large, with many sub-selects, and one DBA is proposing that we rewrite it to break it up into multiple smaller statements (shorter running pieces), "to cut down on how long the locks are held". As this assumes that the shared read locks are held till the complete select statement has finished, if that is wrong (if locks are released when the row, or the page is read) then that approach would have no effect whatsoever....

• Active Directory problems while trying to perfom compare operation

  - by Alex

  I have CentOs 5.5 with Apache 2.2 and SVN installed. Also I have Windows 2003 R2 with Active Directory. I'm trying to authorize users via AD so each user have access to repo if he is a member of corespondent group in AD. Here is my apache config: LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so LDAPVerifyServerCert off ServerName svn.mydomain.com DocumentRoot /var/www/svn.mydomain.com/htdocs RewriteEngine On [Location /] AuthType basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthLDAPURL ldaps://comp1.mydomain.com:636/DC=mydomain,DC=com?sAMAccountName?sub?(objectClass=*) AuthLDAPBindDN [email protected] AuthLDAPBindPassword binduserpassword [/Location] [Location /repos/test] DAV svn SVNPath /var/svn/repos/test AuthName "SVN repository for test" Require ldap-group CN=test,CN=ProjectGroups,DC=mydomain,DC=com [/Location] When I'm using "Require valid-user" everything goes fine, "Require ldap-user" also works. But as soon as I use "Require ldap-group" authorization fails. Trere are no errors in apache logs, but Active Directory shows folowing error: Event Type: Information Event Source: NTDS LDAP Event Category: LDAP Interface Event ID: 1138 Date: 10/9/2010 Time: 1:28:52 PM User: MYDOMAIN\binduser Computer: COMP1 Description: Internal event: Function ldap_compare entered.

• Problems Installing slapd On Ubuntu Server 11.10

  - by Zach Dziura

  I know that there's a Ubuntu-specific StackExchange website, but I thought that I'd ask here because it's a server-specific question. If I'm wrong in my logic... Well, you people are better at this than I am! O=) On with the show! I'm in the process of installing Oracle Database 11g R2 Standard Edition onto Ubuntu Server 11.10. I found a guide on the Oracle Support Forums that walks you through the process fairly easily. Unfortunately, I'm running into issues installing one particular dependency: slapd. When I go to install it, I get this error message: (Reading database ... 64726 files and directories currently installed.) Unpacking slapd (from .../slapd_2.4.25-1.1ubuntu4.1_amd64.deb) ...

The error messages seem straight forward enough, but I have no idea how to debug this. Can anyone offer some assistance? Again, if I'm asking in the wrong place, I apologize. If I'm indeed asking properly, then thank you for any and all help!

• How to download large files when the download size is restricted ?

  - by Rahul

  ? In my office, the network admin has restricted the download limit to a size of 1.8MB for any file. This is for sub ordinates accounts only. But for my manager's PC, there are no restrictions. Is there any way to download files from my PC by using my managers' ip address. I just tried using his ip on my pc but, had the same problem. ? Earlier I was given access to our Linux server from my pc using putty. Then I used to download large files on to the server and then transfer from server to my machine using fire ftp. This transfer worked perfectly fine. But, now I don't have any access to the server. So can I be able to download large files using fire ftp from my own PC ? I'm using Windows XP machine. Please suggest a solution by any possible combination. Thanks.

• Delete on windows vista and seven -- discovery process

  - by M'vy

  Hi SUs! I've recently encountered a problem. Using svn at work I needed to clear some space. As you may know svn directories are full of sub-directories and files. So the delete process begins with a step of discovering the items to be deleted (I guess this is for displaying the progress bar). But in my case it ended up to be still running after I watched Braveheart (Off-topic: good film in my opinion. On-topic: and it last 2h50) and counting 440 000+ files. I finally decided to cut off the process and use the good old cmd with a del <directory> to do the job. (Done in some minutes) So I'm wondering if someone know how to override the system to make it actually begins the process while scanning the other items? At the end, I just want the file to be deleted and I don't care the number of files to be deleted. On the contrary I care about the time it takes. Thanks

• Multiple rack apps on nginx + passenger, one as root, the other not...config help

  - by cannikin

  So I've got two apps I want to run on a server. One app I would like to be the "default" app--that is, all URLs should be sent this app by default, except for a certain path, lets call it /foo: http://mydomain.com/ -> app1 http://mydomain.com/apples -> app1 http://mydomain.com/foo -> app2 My two rack apps are installed like so: /var /www /apps /app1 app.rb config.ru /public /app2 app.rb config.ru /public app1 -> apps/app1/public app2 -> apps/app2/public (app1 and app2 are symlinks to their respective apps' public directories). This is the Passenger setup for sub URIs described here: http://www.modrails.com/documentation/Users%20guide%20Nginx.html#deploying_rack_to_sub_uri With the following config I've got /foo going to app2: server { listen 80; server_name mydomain.com; root /var/www; passenger_enabled on; passenger_base_uri /app1; passenger_base_uri /app2; location /foo { rewrite ^.*$ /app2 last; } } Now, how do I get app1 to pick up everything else? I've tried the following (placed after the location /foo directive), but I get a 500 with an infinite internal redirect in error.log: location / { rewrite ^(.*)$ /app1$1 last; } I hoped that the last directive would prevent that infinite redirect, but I guess not. /foo gets the same error. Any ideas? Thanks!

• Moved servers running Windows Server 2003

  - by Charles

  Our company has two locations and each location has a Windows Server 2003 machine as the DC and several servers, running on two different sub-nets. We are consolidating the locations. I changed the IP address on one of the web servers prior to moving to the main location. I didn't change the IP address on either the DC or the other web servers prior to moving to the main location. Now, only the web server whose IP was changed is able to serve pages. The other web servers are not able to serve pages, cannot be pinged, or be accessed via RDP. Since we don't need the second DC, it has been powered down. When I tried to ping it, the previous IP address was received. My colleague changed the IP address in the DC's DNS, but when I ping it, a timeout error is received. I know that I should have read a lot more before doing this. What can I do to fix it? Thanks, in advance, for your help! Update MarkM, thanks for the info on demoting a DC. That's one of the things I want to do after everything is working. Is there a good, clear article you recommend? Rusty, there are no DMZs involved at this point. I need to set up a DMZ, but that's another project.

• How to migrate Outlook Express mail rules?

  - by ronwest

  I have a home computer that only had a 15Gb C: drive, and ran out of space with all the Microsoft Updates, etc, that keep coming down. So I fitted a 160Gb drive as a C: drive and altered the drive jumpers to make the old C: drive into a slave D: drive, to save migrating documents, etc. I've installed a clean copy of Windows XP SP3 and reassigned the new Outlook Express' mailstore path to point to the old mailstore folder that now has a D: drive letter - and it all works OK. However, my extensive list of mail rules have not been transferred to the new OE and I have not been able to identify how they are stored. To find it I added a new rule to the new OE, exited OE, then searched on the whole computer (including hidden/system files) for files altered around the time I added the rule. I hoped I could just overwrite a new empty file with an old one. But the only files that seem to be changed are Windows system-level files and some bits and pieces in the Windows\PreFetch sub-folder. None of them can be opened as XP has them locked, and none of them have names that are anything to do with email or rules. Does anyone know of any way of migrating OE rules, or do I have to re-enter them by hand? Thanks!

• While using an ntfs smb share for mac users, do symbolic links and extended attributes work?

  - by scape

  We have a majority of mac users but we'd rather support their file sharing using a Windows server with an ntfs drive, or at least a Linux server with ext3. We've had trouble, much trouble, utilizing the OS X server software and after the years are now looking to abandon it. What's mostly holding us back is the fact that the mac users very often utilize symbolic links and other special features that exist for an HFS+ partition. The shared locations are mostly primary storage and not just used as an archive storage location. While there is an option to create symbolic links under ntfs, I'm curious if there is anything I need to look out for if I were to move the files over to a new partition that's hosted from a Windows server from the HFS+ partition; in addition, how well creating a symbolic link from a mac might work. I am also worried about windows backup software and if it will ruin these special sym links, and how placing permissions on sub-folders will work. Alternatively I could remotely backup the files using a mac and Bru, nonetheless I still want to get away from mac server for hosting the shares.

• Why do moving lines become fuzzy on my monitor?

  - by CodeInChaos

  I recently got a new notebook. With moving images there are some graphical issues, and I'd like to know what causes them. None of my earlier monitors exhibited similar issues. Moving high contrast lines become jagged, similar to interleaved videos. When moving a horizontal line vertically those artifacts are colored, when moving a vertical line horizontally they aren't colored. The effect isn't observable in static images. And when moving faster the zone in which it occurs becomes wider. The effect is very visible if I move a window around on the borders of the window and wherever high contrast lines appear. But it appears when watching videos too. The vertical line in that image moves to the right, the horizontal line upwards. The effect is most likely related to the fact that each real pixel consists of different sub-pixels for the different color channels. But how are these causing the observed effect? Is the change at which the different colors change to the destination brightness different? The optical impression is that every second pixel in a chess board like arrangement is adapting slower than it's neighbors. But that doesn't make much sense.

• DVI splitter not working as expected/confusion between DVI-D and -I

  - by Freakishly

  Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P

• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  Hi Geeks, I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• WSUS performance for unneeded updates

  - by mhouston100

  We have a WSUS server serving around 300 PC's and a couple of dozen servers and a discussion came up at work as to what products to include. We have a single SQL 2005 instance on one of the servers and it has NEVER been updated. My first thought was to just tick the box for SQL 2005 and let WSUS do it's thing to upgrade to the latest service pack at least. One of the other guys here has the opinion that having updates that are relevant to only a small selection of hosts would effect the performance of WSUS as a whole, claiming that each update does a 'check' against all the hosts or something similar. My argument is that manually updating these servers is obviously not working as the admins are not paying attention to what is needed. So my question is: Do updates that only effect a sub-set of the hosts effect the overall performance of the WSUS server in relation to ALL the hosts? (disk space is not an issue at this point) Is there any performance justification for or against manually updating small amounts of products? Basically I'm needing a rebuttal against his argument and I'm unable to find any concrete documentation to prove him wrong.

• What Device/System to use as a "router on a stick"

  - by Jeff Leyser

  I need to create several distinct VLANs, and provide a way for traffic to move between them. A "router on a stick" approach seems ideal: Internet | Router with Trunking Capability ("router on a stick") * * Trunk between router and switch * Switch with Trunking Capability | | | | | | | | | | | LAN 2 | LAN 4 | | 10.0.2.0/24 | 10.0.4.0/24 | | | | LAN 1 LAN 3 LAN 5 10.0.1.0/24 10.0.3.0/24 10.0.5.0/24 We have trunk-capable Layer-2 switches. The question is what to use as the router on a stick. My choices seem to be: 1) Use an existing Cisco 5505 ASA firewall. It appears the ASA can do the routing, but it's a 100Mbps device, and so seems sub-optimal at best 2) Buy a router. This seems overkill. 3) Buy a Layer-3 switch. Also seems overkill. 4) Use an existing Linux Box as a router 5) Use a new Linux box as a router' 6) Something I'm not thinking of I think either (4) or (5) is my best option, but I'm not sure how to choose between them. I expect the amount of traffic that has to cross the VLANs to be somewhat small, but bursty. How much load does routing add to a CentOS machine?

• Computer won't start after installing new video card

  - by Vercas

  So, 1 year and 340 days ago I bought a desktop computer. Since then, it has served me well. But lately, I wanted an upgrade, so I bought a new video card. I documented myself about the compatibility, and it is okay. So I opened the case, cleaned up that... dust elemental living inside of it. Unscrewed the plastic thingie on the outside to unscrew the old video card. Because of the stupid arrangement of the ports, I had to unscrew the motherboard to unplug it. So I unscrewed it, removed the old card, put in the new one, moved the motherboard back, screwed it back in, screwed the video card on the holder... thingie, and screwed the plastic thingie back in. Everything went smoothly, nothing had to be forced in/out. I connected the external power supply, closed the computer case, put the tower back in it's place and all the cables back in. When I pressed the power button, the LED turned... some color I can't distinguish. It stayed that way for a second, and then it went off. I tried a bunch of things, including permuting the external power supply arrangement (1 connection, 2 connections and no connections), with no success. And here are some of the specifications: Motherboard manufacturer: Asrock Processor: AMD Athlon II X2 3.0 GHz RAM: 2 x 2GB (had only 1 initially, bought the second plate a bit later) OLD video card: AMD Radeon HD 5450 NEW video card: Gigabyte nVidia GeForce GTX 650 GPU, 1GB GDDR5 128bit PCI-E, Dual-link DVI-Dx2 / HDMI / D-Sub Power supply: 450W + all the requirements I managed to find on the internet are met (+12V 18A or something) More specific information is stored... On that computer. If required, I may open the case again and read the stickers to find more specific information. I can also provide photos if necessary. Any ideas? Suggestions? Something? :|

• At what point does the performance gap between GPU & CPU become so great that the CPU is holding back a system?

  - by Matthew Galloway

  I know that generally speaking for gaming performance the GPU is the primary factor which holds back performance, with everything else such as RAM/motherboard/PSU/CPU being secondary in importance to the graphics card. But at some point the other components ARE going to be significant in holding back the whole system! For instance nobody would be silly enough to play modern games with 512MB RAM and the very latest graphics cards (such as an HD7970) as I bet the performance increase over such a system with only 512MB but a mid range card would be non-existent! Thus it would be a "waste" for such a person to buy any high end graphics card without resolving first the system's other problems. The same point applies to other components, such as if it only had a Pentium II a current high end graphics card would be wasted on it! So my core question is how do you determine at what point for your system is spending on extra GPU power be completely "wasted"? (also, a slightly more nuanced question is trying work out at what point might the extra graphics power not be "wasted" but would be "sub optimal" value for money, when the expenditure should then be split around graphics card and other components. As obviously a gamer shouldn't always just spend on upgrading the graphics card! But needs to balance it out)

• Monitoring instantaneous network throughput at one second intervals?

  - by Shaddi

  For a testing setup I have, I need to monitor the throughput through a "router"* at regular intervals of around 5 seconds or less (sub-second intervals would be very nice, but not required). Ideally, I would be able to generate a file which contained both the number of bytes and packets seen during each interval. I will eventually be generating a time-series of throughput from this data. On a previous setup using an older version of FreeBSD, there was a tool called "bpfmon" which gave me this information. However, I need to do this under a modern version of Linux (namely, Ubuntu 11.04). I have looked at both iptraf and iftop, but these do not appear to provide the resolution I need, nor do they seem to easily allow scraping the data I need. I understand iptables statistics may be able to give me what I'm after, but the examples I've seen of this seem to rely on repeatedly reading and resetting traffic counters, which seems like it could give inaccurate as read/reset is not an atomic operation. I already capture a tcpdump trace of the traffic I'm interested in on the link I want to monitor, so I am open to approaches which simply parse that. I feel like this must be a common problem though, so I am hoping there will be a standard "best practice" tool for accomplishing this. *I say "router" in quotes because I am really talking about a machine with two bridged NICs through which all the traffic I'm interested in passes.

• 'Future-proof' Live Audio Capture & Broadcast [migrated]

  - by maxpowers

  I'm looking to implement some live audio broadcasting functionality within a Ruby on Rails site for a client and was hoping I could get some input from people who have tackled this type of thing before. Essentially what I need to do is capture and record a user's audio (via microhpone, line in, etc), then stream that to 1,000+ listeners with very little latency, like sub 2 second if possible. So it looks like we've got 3 parts: Web-based audio capture (likely with Flash or JS) Server to accept audio feed and stream to listeners (likely Icecast or Wowza) Actual audio player (maybe HTML5 w/ Flash as a fallback? Maybe this jPlayer fork) Does RTMP makes sense here? Or maybe HTTP? What's the most 'future-proof' way to make this happen? Building with mobile in mind, but still want to be able stream to anyone. I've found lots of potentially helpful threads and software but I'm struggling to get an idea of how it all fits together. I'm a front end guy and way out of my comfort zone so if anyone has insights to offer, I'd love to hear them.

• How to (properly) back up a live QEMU/KVM VM?

  - by Roman

  I'm currently engineering a backup solution for KVM VM's as an additional measure to traditional backups. Unfortunately, all currently (August 2013) existing solutions I came across so far either: do not ensure a consistent backup of the VM (losing RAM state, creating a dirty image, or other things), or require lengthy downtime (complete VM shutdown while backing up). I'm aware of QEMU/libvirt's functionality of taking snapshots, however, it's not yet usable since: image-internal snapshots present you with an ever-changing image file, resulting in a likely dirty backup (assuming one uses qcow2 images at all). one cannot yet merge a currently active external snapshot into the original backing image ("blockcommit"). Out of the above reasons, I'm now implementing a script that: Saves the VM's state and halts it Sets up a devicemapper snapshot(s) where the VM's disk images and state reside Resumes the VM Mount the snapshot(s) of step 2. Backs up the VM's disk and state (configuration for convenience) Merges back the snapshot(s). If I got everything right, this will take consistent backups of VM's with only seconds (if at all, since 1-3 is fast, possibly sub-second) of downtime. Of course, when restoring, the VM will be way in the past, but at least giving me the option of an orderly shutdown/reboot. Am I missing something with this solution? Or has someone indeed already implemented this?

• Data recovery; nearly 1 tb of movies on a WD 3.5 tb personal cloud drive disappears with scanty traces

  - by Effector Dhanushanth

  I have a great collection of movies that I had stored in a logical mesh of folder on my 3.5 tb WD personal cloud drive. I woke up 1 morning and found that everything was fine with my data on this drive, except for my movie collection: There were two great folders, one "2sort" nd the other "segregated". out of all the segregated sub folders, only letter C D and 2 or 3 others remain. and the 2 sort folder, which has umpteen subfolders, amounting to more than 0.5 tb. is.. it's just gone!! this is a great downfall.. now this is a personal cloud drive and has no usb port etc. unfortunately to hardwire and recover files.. now I'm sure there are softwares out there that can help me recover my beloved movies from such an interestingly "hard-to-reach" (should I say?) device? what may that software be compadre, my happiness lies within your answer.. thank you.. remember, recovery software or (WD) personal cloud. :) these ovies were All, "hand-picked", over the course of ten years.. I just never catalogued my collection.. if I could just get the "list" of my lost collection, that'd be enough.. recovering em would be a bonus.. but they out to be damaged if I were to somehow recover you know? still, I'm certain they're all intact.. I guess the file index just got corrupted.. There surely is a veil of some sort that need to be thrown or pushed aside to reveal my movies.. what software can do/does that? thanks immensely!

• De-duplicating backup tool on a block basis? [closed]

  - by SST

  I am looking for an (ideally free as in speech or beer) backup tool for Unix-like OS which can store deduplicated backups, i.e. only nonredundant content takes up additional space. I already looked at dirvish (my first candidate) and rsnapshot which use hardlinks to achieve deduplication on a per-file level. However, as I want to back up large files (Thunderbird mailboxes 3GB, VMware images 10GB), such file are stored again entirely even if just a few bytes change. Then there are rsync-based tools like rdiff-backup which only store deltas and a current mirror. However, as the deltas are generated against each previous mirror, it is difficult to fine-tune the retention granularity (only keep one backup after a week, etc.) because the deltas would have to be re-evaluated. Another approach is to partition content into blocks and store each block only if it is not stored yet, otherwise just linking it to the first occurrence. The only tool I know of that does this by now is obnam (http://liw.fi/obnam), and it even supports zlib-compression and gpg-encryption -- nice! But it is very slow, AFAICT. Does any one know any other, solid backup software which supports deduplication on a sub-file level, ideally with at least some management options (show/select/delete generations...)?

• Todo/task manager for android and desktop linux

  - by RiaD

  I'm looking forward to Task/ToDo Manager. It should work under Android, Linux(or Web). If it's very cool, one of them is OK too, Android is preferable in this situation. Necessary features: Russian or English language Possibility to mark task as finished Interesting features: (I want as more, as possible, while it's OK, if some of them isn't avaliable) Nice and easy-to-use interface Possibility to choose finish time for task. After that it's showed as overdue. Possibility to choose start time for task. Before it task is inactive and maybe shown or hide Possibility to add nested tasks. Task marks completed when all sub-tasks are completed. Possibility to make dependencies. If A depends on B, and B isn't finished yet, A is inactive as in third feature. Possibility to create task in a moment without fill-all-this-forms Syncronization between version(Android to linux or Android to web) Notification (on Android only) Features, that I'm not interested in: Creating more than one todo list sharing ToDo's I've seen couple of managers. Best I've seen now is Task Coach for Linux, but I don't very like its interface, and there is no version for Android.
