• unix command to verify span of word in text

  - by Ocasta Eshu

  What unix command(s) can I use to determine the line span that a word appears in text? The "span" being equal to the line number of the last instance of a word minus the line number of the first instance of the word. 1| unix is on two lines 2| once above, and once below 3| unix In the example above the "span" of 'unix' would be 2 (3-1). So far I've been trying to make use of grep -n but I don't think that grep is powerful enough. Maybe some use of sed or awk? Thanks!

• Files on ext4 on Drobo with corrupt, zero-ed out blocks

  - by Patrick

  I have a 2TB ext4 file system (Ubuntu running Linux kernel 2.6.31-22-server x86_64). This file system is the second drive on a Drobo box plugged in via USB. We've not had problems on the first drive (Drobo limits drive size to 2TB due to some OS limitations, so if you have more space than that it appears as two separate drives). I am sharing this files with Samba (smbd 3.4.0) with a mix of Windows and Linux workstations. Recently we've been experiencing some data corruption in multiple files. In many cases I have an un-corrupt original file stored on one of the workstations. These are binary files of various formats, (e.g. SQLite, but others as well). I used "split" to split a corrupt and uncorrupt file into 4096 byte chunks (this is the block size of the ext4 file system). I then ran md5sum on pairs of chunks and discovered that the chunks matched in many cases and in every case where they did not match, the corrupt chunk was a solid chunk of zeroes (620f0b67a91f7f74151bc5be745b7110 for what it's worth). I'm trying to track down a culprit but am a bit at a loss. I don't believe Samba is at fault since I'm using it without issue on the first drive exported by the Drobo. What can I do to narrow this down and find out what's going on?

• What are my options for sharing music between Windows & Ubuntu on the same network?

  - by jgbelacqua

  We have a few Windows(XP & 7) and Ubuntu machines in the house sharing a wireless connection, and want to share music between them. If possible, I would like to be able to serve music from both Windows and Ubuntu (but it doesn't have to be the same time). I don't know much about sharing folders or streaming, but I'm guessing both would be options (that is, using a local client to access a shared song or a local client to access a shared stream). I want to be able to share the music between the systems as simply as possible. Bonus points (but not requirements) for cross-platform -- same application on both Windows and Ubuntu? available on startup (via daemon or autostart or whatnot) open source More info: All systems have dynamic addresses (DHCP) supplied from the ISP-supplied wireless router. There are several Gigabytes of music on one Windows XP box and one Ubuntu 10.10 The music is not well-sorted (I'm thinking this might have an impact on UI usability). Only has to be available internally (private address space behind the wireless router) bandwidth is not a problem We don't have (legitimate) admin access to the wireless router

• Why do I bother with RAID 10 ?

  - by GrumpyOldDBA

  Before I post anything I just want to clarify what I mean by RAID 10 , this is sets of mirrored pairs that have been striped as against a RAID 0 which has been mirrored. I've just had a disk failure in the data array for one of my dev servers, it's an eight disk raid 8, no real worries, replace disk and off we go - but no - the HP engineers told me from the diagnostics ( done to ensure I got the right replacement under warranty ) that not only had a disk failed but I'd lost all the data...(read more)

• VMWare Fusion Folder Sharing Not Working with Server

  - by Dave Long

  I have a Ubuntu Server running in VMWare Fusion 3.1.2 on my MacBook Pro for Java development and all my projects sit on my Mac in ~/Workspace/ColdFusion. I had ColdFusion/ shared with my VM through the VMWare tools, and it was working perfectly up until friday when the folder sharing just stopped. No updates on either mac or linux besides an iTunes update. I tried uninstalling the VMWare tools and reinstalling them but I get an error at the end of the install. It appears that when I reinstall the tools there are files left over from the old installation. Is there a way to force the unsinstall script to completely uninstall and remove all files for the VMWare-Tools? I know the shared folder used to mount at /mnt/hgfs/ColdFusion.

• Best CMS to handle short snippets of text?

  - by Federico Poloni

  I have to install a CMS to manage a set of mathematical problems, i.e., our main content will be short (~3 lines) snippets of text. We need the ability to add comments and categories/tags, possibly with a powerful search function combining different constraints on the categories. A crucial ability is the possibility to combine the results of a search in the same page to produce a (printable) problem sheet: not many CMS's seem to be able to do so, and it is difficult for me to test every one for this specific function. Do you guys know of a CMS that is capable to return formatted search result in this fashion? Thanks in advance!

• Would you expect this then ?

  - by GrumpyOldDBA

  I've just been working through a database looking for log tables which can have data aged out, or deleted if you like. I was using SSMS for this and used the default right click select top 1000 rows as a quick view of the data. Establishing that I had unwanted data in such a table I deleted based upon getdate()-30 , nearly 7,000 rows deleted, I then highlighted the top 1000 rows query and re-ran query, surpisingly I still got the same result set with 2006 dates in it, and 1,000 rows.

• Does TOR protect privacy of bittorrent clients like Transmission?

  - by rocky

  I am using the Tor bundle and its included browser to initiate torrent downloads with the Transmission client included with Lubuntu. Clicking on a torrent link provides a warning message that external apps are NOT protected by Tor and clicking ok results in normal Transmission start and it begins the download. I have seen assertions in another post answer that Tor starts Transmission using a different profile than the normal $HOME/.config/transmission. However, I see no evidence of the referenced different profile on my system ( $HOME/tor-browser_en-US/.config/transmission). The normal privacy settings provided within Transmission seem inadequate for privacy according to what I have read. Has something changed in how Tor bundle browser (firefox) interacts with supporting apps like Transmission. Tor bundle otherwise seems to be operating correctly. I asked the question in the post but it was deleted by moderator for some reason not given

• Convert filenames to their checksum before saving to prevent duplicates. Is is a smart thing to do?

  - by Xananax

  TL;DR:what the title says I am developing some sort of image board in PHP. I was thinking of changing each image's filename to it's checksum prior to saving it. This way, I might be able to prevent duplicates. I know this wouldn't work for two images that are the same but differ in size or level of compression or whatnot, but this method would allow for an early check. What bugs me is that I never saw this method implemented anywhere, so I was wondering if there is a catch to it. Maybe it is just more efficient to keep the original filename and store the hash in DB? Maybe the whole method is just not useful and my question is moot? What do you think? On a side note, I don't really get how hashes are calculated so I was wondering, if my first question checks out, if it would be possible to calculate the likeness that two images are similar by comparing hashes (levenshtein or something of the sort).

• How to replace emacs keybindings with vim keybindings in OS X GUI-level text fields

  - by post meridiem

  I'm fairly fluent with VIM, but find myself having to use GUI programs (in OS X) and their awkward editing modes more and more frequently for my work. I know that OS X lets you use basic emacs keybindings in most textfields (browser window/bar, etc.). I'm wondering if it's possible to switch the emacs keybindings to vim keybindings for those GUI-level input areas. I understand that it might be possible to do that key-by-key in the keyboard layout preference pane. But that approach seems limited, cumbersome, and not very elegant. I'm thinking--and I may well be wrong here--that since OS X already ships with VIM installed, there should be a way to change a preference file deep in the system that maps VIM instead of emacs keybindings to the GUI text/input areas. Does anyone know if this is a) theoretically possible, or if there's something about how OS X maps emacs keybindings to its GUI interface that would make this impossible; and b) how/where that could be done?

• How do I format a text file for IIS Mailroot Pickup so that it sends an e-mail with attachments?

  - by Ben McCormack

  How do I need to format a text file so that it can be read by an SMTP service to send an e-mail that has an attachment? We have a server where we are using II6 SMTP to send mail from a Pickup folder. The goal is to drop a properly formatted text file into Mailroot\Pickup and then the file will be automatically processed and sent to the correct SMTP recipient. For simple files, this works correctly. Here's an example of a simple file that works (domain names changed): From:[email protected] To:[email protected] Subject:Hello World! Test Body Of The E-mail When I drop a text file containing the above contents into the Mailroot\Pickup folder, it sends correctly. However, I haven't been able to figure out how to get an attachment to work. I found some material that explained how to encode an SMTP attachment and another tool for simple base64 encoding conversion. Using the information on those pages, I came up with the following text: From:[email protected] To:[email protected] Subject:Hello World! MIME-Version: 1.0 Content-Type: text/plain; boundary="Attached" Content-Disposition: inline; --Attached Content-Transfer-Encoding: base64 Content-Type: text/plain; name="attachment.txt" Content-Disposition: attachment; filenamename="attachment.txt" VGhpcyBpcyBhIHRlc3Qgb2Ygc29tZXRoaW5nIHRvIGVuY29kZS4NCk5ldyBsaW5lDQpOZXcgTGlu ZQ0KIkhlbGxvdyIgISEhDQo9PT09ICcgZnNkZnNkZiAxMjM1NDU2MzQzNA== --Attached-- However, when I place the above text in a file and drop it into Mailroot\Pickup, it doesn't send an attachment correctly. Instead, an e-mail shows up with the following in the body of the e-mail: MIME-Version: 1.0 Content-Type: text/plain; boundary="Attached" Content-Disposition: inline; --Attached Content-Transfer-Encoding: base64 Content-Type: text/plain; name="attachment.txt" Content-Disposition: attachment; filenamename="attachment.txt" VGhpcyBpcyBhIHRlc3Qgb2Ygc29tZXRoaW5nIHRvIGVuY29kZS4NCk5ldyBsaW5lDQpOZXcgTGlu ZQ0KIkhlbGxvdyIgISEhDQo9PT09ICcgZnNkZnNkZiAxMjM1NDU2MzQzNA== --Attached-- I can't figure out what I need to do to format the text file so that the SMTP service correctly sends attachments.

• Firefox 4 is displaying all text as "bold"

  - by Mateo

  I installed Firefox 4 this morning excited to checkout some of the new HTML 5 features that have been implemented and found that all text was displayed in a bold font. Here is the comparison with what Firefox 4 is displaying on my machine and Chrome. It is getting really annoying. So far I've... Emptied the cache/history/etc. Re-installed the various core fonts (Arial, Courier, Times New Roman, etc.) Checked the font defaults in FF4. The interesting part to me is that I had FF3.6x on this machine with no problems whatsoever and now this. Any ideas? System Description Windows 7 (x64) Update I just found out that this is happening in IE9 (final) as well. Must be something with the system fonts. Like I said before, this wasn't happening pre-FF4.

And on Word documents, anything to do with Track Changes is also blacked out. I have tried restarting the Print Spooler, and reinstalling the printer, but this does not help.

• Download images and other documents from external websites

  - by user359650

  We're running a website which enables users to download documents about our company, such as: -wallpapers with the company logo. -company logos in various flavours. -media kits in pdf format. Since these files are quite big in size (some reach 1MB), we no longer want them to be downloaded from our website directly as it's consuming our bandwidth. Accordingly we've been looking into document sharing services. For instance we found Scribd which could allow us to share pdf files, but not our wallpapers and logos which are in png format. Is there a free service we can use for our users to reliably download any type of files we want to host? (ideally on a service which allows users to easily browse through our files).
