• Solr Autosuggest

  - by rahul

  Hi, I am using Solr (1.4) AutoSuggest feature using termsComponent. Currently, if I type 'goo' means, Solr suggest words like 'google'. But I would like to receive suggestions like 'google, google alerts, ..' . ie, suggestions with single and multiple terms. Not sure, whether I need to use edgengrams for that. for eg, indexing google like 'go', 'oo', 'og', ... . But I think I don't need this, Since I don't want partial search. Please let me know if there is any way to do multiple word suggestions . Thanks in Advance.

• Software RAID 10 on Linux

  - by vpetersson

  For a long time, I've been thinking about switching to RAID 10 on a few servers. Now that Ubuntu 10.04 LTS is live, it's time for an upgrade. The servers I'm using are HP Proliant ML115 (very good value). It has four internal 3.5" slots. I'm currently using one drive for the system and a RAID5 array (software) for the remaining three disks. The problem is that this creates a single-point-of-failure on the boot drive. Hence I'd like to switch to a RAID10 array, as it would give me both better I/O performance and more reliability. The problem is only that good controller cards that supports RAID10 (such as 3Ware) cost almost as much as the server itself. Moreover software-RAID10 does not seem to work very well with Grub. What is your advice? Should I just keep running RAID5? Have anyone been able to successfully install a software RAID10 without boot issues?

• Excel: count number of unique/distinct row in range with condition

  - by Bertvan

  I have a an excel sheet with: in Col A: week numbers in Col B: dates (timesheet entries) I need to know the number of days worked for each week, so I need to the number of unique date entries per week number. I found formula's (both array as non-array) that handle this for a fixed range, but I want to have the results in another column per week number. So, the result of the added dataset below would be (the colon is just for clarity): 14: 2 15: 3 17: 6 20: 2 21: 3 If this is the source data: 14: 4/04/2012 14: 4/04/2012 15: 10/04/2012 15: 10/04/2012 15: 11/04/2012 17: 26/04/2012 17: 26/04/2012 17: 26/04/2012 17: 26/04/2012 17: 27/04/2012 17: 27/04/2012 20: 14/05/2012 20: 14/05/2012 21: 23/05/2012 21: 23/05/2012 21: 25/05/2012

• Implications and benefits of removing NT AUTHORITY\SYSTEM from sysadmin role?

  - by Cade Roux

  Disclaimer: I am not a DBA. I am a database developer. A DBA just sent a report to our data stewards and is planning to remove the NT AUTHORITY\SYSTEM account from the sysadmin role on a bunch of servers. (The probably violate some audit report they received). I see a MSKB article that says not to do this. From what I can tell reading a variety of disparate information on the web, a bunch of special services/operations (Volume Copy, Full Text Indexing, MOM, Windows Update) use this account even when the SQL Server and Agent service etc are all running under dedicated accounts.

• Huge google impression drop after cleaning html

  - by olgatorresfoundation

  Good morning, I am the webmaster of a non-profit organization that donates grants to colorectal cancer research projects and funds various colorectal cancer information campaigns. We have three domains: www.fundacioolgatorres dot org (Catalan) www.fundacionolgatorres dot org (Spanish) www.olgatorresfoundation dot org (English) So what happened? I redesigned olgatorresfoundation on the 20th and the fundacionolgatorres on the 30th of May. In both cases, exactly two days later, the number of impressions on both dropped to a halt. Granted, we did not have the traffic of Microsoft, but a 90% decrease a disaster of incredible proportions for us. My only real changes were cleaning up the old ineffective HTML to a cleaner form (mostly moving away from redundant table construction to a table-less view). Here is a before and after snapshot of what the change looks like: Before: http://www.fundacioolgatorres.org/aparell_digestiu/introduccio/ (unchanged page in Catalan) After: http://www.olgatorresfoundation.org/digestive_system/introduction/ (changed page in English) Anybody has a clue to what just happened? Why should a normal, sane html improvement be punished and so dramatically? No URLs have been changed, neither have page names or descriptions. Possible secondary question: If it is so that Google sees it as a major overhaul and decides to drop the pagerank sharply, does it come back to pre-change levels if the content "checks out" or will the page start over from scratch earning those pagerank points (which would mean that we would have to wait 6 months for the pages to recover to the level they had two weeks ago)? (duplicated from productforums.google dot com/forum/#!category-topic/webmasters/crawling-indexing--ranking/YsnyX0JzOpY, hoping to reach a wider audience)

• Safer RAID5 rebuilds using partially failed disks?

  - by arcticmac

  There have been lots of articles posted recently about how RAID5 is dangerous because of long resilver times, and in particular because of increasing chances of encountering a URE during the resilver. Obviously this is a significant concern. However, it seems that in many cases of interest (as long as you're keeping some kind of eye on your disks), when it comes time to rebuild the array, the disk that I'm replacing is still mostly readable. If you try to explain this predicament to the average layperson, they are typically very confused as to why you have two almost completely functional disks but can't produce one working array. It seems to me that there ought to be some way to take advantage of this to make rebuilds safer, as long as I'm willing to have the RAID5 be read-only for a couple of days while it rebuilds. Conceptually, what I have in mind looks something like this: When a disk fails, immediately take the RAID5 offline or mount it read-only Attach a new disk (either in a spare bay, or externally via eSATA) and begin rebuilding it to replace the failed one. If known, perhaps start with the stripes in which the failure occurred, to minimize the chances of losing those if another disk fails. In the event that a second disk experiences a URE or other failure during the rebuild, try to source that data from the disk that is being replaced. Presumably if this happens, more rebuilding would be necessary. When complete, shut down the server, swap the replacement drive into the original bay if desired, and bring the array back up. Obviously such a process would not be appropriate for applications where uptime is critical or data loss cannot be tolerated, but it seems to me that this could help considerably to improve the reliability of RAID5. I assume that there's not a good way to implement a recovery like this at present, given that I haven't seen any indication of tools that are designed to do this, and that it seems like it would be rather obtuse to work out manually. Are there also technical issues with it that I haven't thought of (I'm still fairly new to RAID stuff)? Any thoughts on how hard something like this would be to implement (e.g. in linux md raid)?

• How to get search engines to properly index an ajax driven search page

  - by Redtopia

  I have an ajax-driven search page that will allow users to search through a large collection of records. Each search result points to index.php?id=xyz (where xyz is the id of the record). The initial view does not have any records listed, and there is no interface that allows you to browse through all records. You can only conduct a search. How do I build the page so that spiders can crawl each record? Or is there another way (outside of this specific search page) that will allow me to point spiders to a list of all records. FYI, the collection is rather large, so dumping links to every record in a single request is not a workable solution. Outputting the records must be done in multiple requests. Each record can be viewed via a single page (eg "record.php?id=xyz"). I would like all the records indexed without anything indexed from the sitemap that shows where the records exist, for example: <a href="/result.php?id=record1">Record 1</a> <a href="/result.php?id=record2">Record 2</a> <a href="/result.php?id=record3">Record 3</a> <a href="/seo.php?page=2">next</a> Assuming this is the correct approach, I have these questions: How would the search engines find the crawl page? Is it possible to prevent the search engines from indexing the words "Record 1", etc. and "next"? Can I output only the links? Or maybe something like:

• Need to sanity-check my .htaccess, especially Limit GET POST line for Google repellent

  - by jose

  I need a sanity check on this .htaccess (from a WordPress site) I inherited from a 5 month+ old site. What's the symptom? Google + Bing crawl, but don't index any of the pages. Let me be clear: I'm not mad about "not ranking high." I think something is (accidentally) rejecting search engine indexing. I am not an expert on .htaccess, but one part especially looked funny, the Limit GET POST line. Is it not weird to have both Allow and Deny all, with no parameters? Also, I've ruled out robots.txt, but if I were you I'd want to see it, so here it is: User-agent: * Crawl-delay: 30 And here's the more suspect .htaccess: # temp redirect wordpress content feeds to feedburner <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC] RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC] RewriteRule ^feed/?([_0-9a-z-]+)?/?$ http://feeds.feedburner.com/anonymousblog [R=302,NC,L] </IfModule> # temp redirect wordpress comment feeds to feedburner <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC] RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC] RewriteRule ^comments/feed/?([_0-9a-z-]+)?/?$ http://feeds.feedburner.com/anonymous_comments [R=302,NC,L] </IfModule> <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti* <Limit GET POST> order deny,allow deny from all allow from all </Limit> <Limit PUT DELETE> order deny,allow deny from all </Limit> php_value memory_limit 32M Adding header by request: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="robots" content="noindex,nofollow" /> <meta name="description" content="buncha junk i've deleted." /> <meta name="keywords" content="keywords i've deleted" /> <meta name="viewport" content="width=device-width" />

  - by Pinal Dave

  Earlier this week Microsoft has announced SQL Server 2014. The release date of Trial of SQL Server to be believed later this year. Here are few of the improvements which I was looking forward are there in this release. Please note this is not the exhaustive list of the features of SQL Server 2014. This is the a quick note on the features which I was looking forward and now will be available in this release. Always On supports now 8 secondaries instead of 4 Online Indexing at partition level – this is a good thing as now index rebuilding can be done at a partition level Statistics at the partition level – this will be a huge improvement in performance In-Memory OLTP works by providing in-application memory storage for the most often used tables in SQL Server. (Read More Here) Columnstore Index can be updated – I just can’t wait for this feature (Columnstore Index) Resource Governor can control IO along with CPU and Memory Increase performance by extending SQL Server in-memory buffer pool to SSDs Backup to Azure Storage You can additionally download SQL Server 2014 Datasheet from here. Which is your favorite new feature of SQL Server 2014?

• How do I align my partition table properly?

  I am in the process of building my first RAID5 array.

• optimizing file share performance on Win2k8?

  - by Kirk Marple

  We have a case where we're accessing a RAID array (drive E:) on a Windows Server 2008 SP2 x86 box. (Recently installed, nothing other than SQL Server 2005 on the server.) In one scenario, when directly accessing it (E:\folder\file.xxx) we get 45MBps throughput to a video file. If we access the same file on the same array, but through UNC path (\server\folder\file.xxx) we get about 23MBps throughput with the exact same test. Obviously the second test is going through more layers of the stack, but that's a major performance hit. What tuning should we be looking at for making the UNC path be closer in performance to the direct access case? Thanks, Kirk (corrected: it is CIFS not SMB, but generalized title to 'file share'.) (additional info: this happens during the read from a single file, not an issue across multiple connections. the file is on the local machine, but exposed via file share. so client and file server are both same Windows 2008 server.)

• Outlook Search Folder - Unread Mail in shared mailbox

  - by Garrett

  I have a user who is trying to configure the Unread Mail search folder for a shared mailbox in Outlook 2007. I believe last time we accomplished this by doing an advanced find, and saving the search. However, on this computer I can't search more than one folder of the shared mailbox at a time. Everything I have read online says this isn't possible, but we have one user who has it set up and working perfectly. There's no additional software or indexing, not even Windows Desktop Search 4.0 updates installed.

• 256 SSD / 2TB Internal drive, i7, 16GB RAM.. explorer.exe still slow

  - by web_dvlp_sd

  OK, so I just got done tweaking my brand new PC and explorer.exe still manages to be sluggish not as snappy as I'd like or expected at all. Specs are i7 4th gen processor, 16GB RAM, windows 7 64 home premium on 256GB SSD, secondary internal 2TB drive. I assumed system would be lightning fast, been doing a bunch of researching and switched out a lot of different settings including enabling/disabling indexing, turning pagefile on/off or placing it on separate drive, turning folder optimization options on/off.. changes have been minimal or none at all. Any further advice or anything I might be missing, besides a new/repair install? PC is literally 3 days old I don't feel like I need a new install at all

• How to prevent Mac OS X creating .DS_Store files on non Mac (HFS) Volumes?

  - by sudo petruza

  Is there a way to prevent Mac OS X creating .DS_Store and other hidden meta-files on foreign volumes like NTFS and FAT? I share an NTFS partition with data like Thunderird & Firefox's profiles and apache's DocumentRoot, between Mac OS X and Windows, which is very handy. I don't mind if Mac OS X is not capable of indexing or otherwise doing the neat things those metafiles are for. Note: It's not shared over a network, both operating systems and the shared partition coexist on the same disk, on the same machine.

• Experience with AMCC 3ware 9650se raid cards? Ours seems dead

  - by antiduh

  We have a 8-port 3ware 9650se raid card for our main disk array. We had to bring the server down for a pending power outage, and when we turned the machine back on, the raid card never started. This card has been in service for a couple years without problems, and was working up until the shutdown. Now, when we turn the machine on, the bios option rom that normally kicks in before the bootloader doesn't show up, none of the drives start, and when the OS tries to access the device, it just times out. The firmware on it has been upgraded in the past, so it's possible we've hit some sort of firmware bug. We're using it in a Silicon Mechanics R272 machine with gentoo for the OS. The OS eventually boots, but alas, without the card. We've ordered a new one, but I'm worried that if we replace the card it won't recognize the existing array. Has anybody performed a card swap before? Any help would be greatly appreciated.

• Gathering all data in single iteration vs using functions for readable code

  - by user828584

  Say I have an array of runners with which I need to find the tallest runner, the fastest runner, and the lightest runner. It seems like the most readable solution would be: runners = getRunners(); tallestRunner = getTallestRunner(runners); fastestRunner = getFastestRunner(runners); lightestRunner = getLightestRunner(runners); ..where each function iterates over the runners and keeps track of the largest height, greatest speed, and lowest weight. Iterating over the array three times, however, doesn't seem like a very good idea. It would instead be better to do: int greatestHeght, greatestSpeed, leastWeight; Runner tallestRunner, fastestRunner, lightestRunner; for(runner in runners){ if(runner.height > greatestHeight) { greatestHeight = runner.height; tallestRunner = runner; } if(runner.speed > ... } While this isn't too unreadable, it can get messy when there is more logic for each piece of information being extracted in the iteration. What's the middle ground here? How can I use only a single iteration while still keeping the code divided into logical units?

• Animating Tile with Blitting taking up Memory.

  - by Kid

  I am trying to animate a specific tile in my 2d Array, using blitting. The animation consists of three different 16x16 sprites in a tilesheet. Now that works perfect with the code below. BUT it's causing memory leakage. Every second the FlashPlayer is taking up +140 kb more in memory. What part of the following code could possibly cause the leak: //The variable Rectangle finds where on the 2d array we should clear the pixels //Fillrect follows up by setting alpha 0 at that spot before we copy in nxt Sprite //Tiletype is a variable that holds what kind of tile the next tile in animation is //(from tileSheet) //drawTile() gets Sprite from tilesheet and copyPixels it into right position on canvas public function animateSprite():void{ tileGround.bitmapData.lock(); if(anmArray[0].tileType > 42){ anmArray[0].tileType = 40; frameCount = 0; } var rect:Rectangle = new Rectangle(anmArray[0].xtile * ts, anmArray[0].ytile * ts, ts, ts); tileGround.bitmapData.fillRect(rect, 0); anmArray[0].tileType = 40 + frameCount; drawTile(anmArray[0].tileType, anmArray[0].xtile, anmArray[0].ytile); frameCount++; tileGround.bitmapData.unlock(); } public function drawTile(spriteType:int, xt:int, yt:int):void{ var tileSprite:Bitmap = getImageFromSheet(spriteType, ts); var rec:Rectangle = new Rectangle(0, 0, ts, ts); var pt:Point = new Point(xt * ts, yt * ts); tileGround.bitmapData.copyPixels(tileSprite.bitmapData, rec, pt, null, null, true); } public function getImageFromSheet(spriteType:int, size:int):Bitmap{ var sheetColumns:int = tSheet.width/ts; var col:int = spriteType % sheetColumns; var row:int = Math.floor(spriteType/sheetColumns); var rec:Rectangle = new Rectangle(col * ts, row * ts, size, size); var pt:Point = new Point(0,0); var correctTile:Bitmap = new Bitmap(new BitmapData(size, size, false, 0)); correctTile.bitmapData.copyPixels(tSheet, rec, pt, null, null, true); return correctTile; }

• Backing Up vs. Redundancy

  - by TK Kocheran

  I'm currently in stage 2 of 3 of building my home workstation. What this means is that my RAID-0 array of solid state disks will be backed up nightly to a RAID-5 or RAID-6 array of traditional spinning hard disks. However, it recently dawned on me that redundancy is not backup. The main reason for setting up a RAID array with redundancy was to protect myself in the event of a drive failure to serve as an effective backup solution. Wait. What if a bolt of lightning finds a way to travel into my house, through my surge-protector, into my power supply and physically destroys all of my hard disks and SSDs? Well, in that case, I guess I'd be fine because I generally keep most important files (music, pictures, videos) stored in multiple places like on my laptop, my wife's laptop, and an encrypted USB hard drive. Wait. What if a giant hedgehog meteor attacks my house from space traveling at mach 3 and all machines and hard disks are blown to smithereens. Well, I guess I could find a way to do ridiculously slow and cumbersome rsyncs or backups to Amazon's Glacier. Wait. What if there's a nuclear apocalypse... and at this point I start laughing hysterically. At what point does backing up become irrelevant? I completely understand situation one (mechanical drive failure), situation two (workstation compromised or destroyed somehow), possibly even situation three (all machines and disks destroyed), but situation four? There's no questioning the need for backups. None. However, there are three questions I'd really like addressed: To what level should one backup? I definitely understand the merits of physical disk redundancy. I also believe in keeping important files on multiple machines and thinning out the possibility of losing all of my files. Online backups make sense, but they beg the following question. What should I be backing up remotely and how often? It's no problem storage-wise to back up important files (music, pictures, videos) and even configuration and temporal data for all of the machines in my network (all Linux based)... albeit locally. Transferring to the cloud is another story. Worst-case scenario, if I lost all of my configuration for my individual computers, the reality is that I probably lost the machines too. The cloud is a long way away from here; I can run backups over CAT-6 here and see 100MB/s easily, but I'm afraid that I'm only going to see 2MB/s at best when transferring up to the cloud.

• asp.net mvc vs angular.js model binding

  - by aw04

  So I've noticed a trend lately of .net web developers using angular.js on the client side of applications and I've become more curious as I play around with angular and compare it to how I would do things in asp.net mvc. I'll give a quick example of what really got me thinking. I recently came across a situation at work (I work in a .net environment) where I needed to create a table bound to a collection of objects that had the ability to add and remove rows/items from the collection. I had an add button that created a new object and appended a row to the end of the table, and a remove button in each row to remove a particular object/row. Using asp.net mvc, I first found myself making an ajax call to the server for each operation, updating the server side model, and refreshing part of the page to show the result in the table. This worked but I didn't really like the idea of calling the server to update the model each time, so I tried to come up with a solution to do this on the client side. It turned out to be quite a task, as I had to generate the html on add with validation and all and the correct indexing for the model binding to work. It got worse on remove, as I ended up with a crazy string replace function to recreate the indexes on each item to satisfy the binding requirements (if an item other than the last is removed, the indexes are no longer correct). Now out of curiosity, I tried to recreate this at home in angular (which I had no experience with) and it took me all of about 10 minutes with simple functions to add and remove items from the client side model. This is just one example, but it seems to me that I'm able to achieve the same results with far fewer calls to the server in angular because of the fact that it binds to a client side model. So my question is, is this a distinct advantage of using a javascript mvc framework or am I somehow under utilizing the power of asp.net mvc and am I right in thinking that these operations should be done on the client and have no business requiring calls to the server?

• Disable comments / Spam protection

  - by SamIAm

  My client site is built in Silverstripe, there is a news page, and it allows people to leave comments. Unfortunately we've got loads of spam emails. I'm new to this, is there any way we can disable the comment field by default? How do I do it? Alternatively is there easy way for me to install a spam protection? Thanks heaps. Sam Update - Because this is someone else's code, I just realised that they have some sort of spam protection already, so we are trying to disable comments now. I have manage to set no comment as default by changing file BlogEntry.php static $defaults = array( "ProvideComments" => true, 'ShowInMenus' => false ); to static $defaults = array( "ProvideComments" => false, //changed 'ShowInMenus' => false ); Am I on the right track to disable comments by default? Also how can I stop on the news page showing xxx comments link? eg Test Posted by Admin on 21 June 2011 | 3 Comments Tags: P This is a test.... 3 comments | Read the full post Thanks. S:)

• Stop RAID 5 from Initializing

  - by Antz

  Hi, I am trying to follow Ictinike's guide on Recovering Intel RAID "Non-Member Disk" Error found here, Ictinike's RAID recovery Guide I have recreated my RAID array as per the instructions. However my RAID array status is then automatically set to: INITIALIZE When I boot back into my Windows XP desktop, the Intel Matrix Storage Utility begins to "Initialize" my drives. This is a long slow process that will take about 20 hours. I suspect all my data will be lost. I have gone back into my bios and disabled my RAID controller to prevent any further initialization and data loss. I have read that initialization will cause data loss. I've also read somewhere that it won't. I am not so confident in the latter. Is there anyway to stop this initialization process so I can continue to follow the steps in the recovery guide? Some system specs: ABIT IP35 Pro Motherboard ICH9R on board RAID controller

• updatedb & locate command problem - Files from external hard drive are no longer indexed after rebooting

  - by user784637

  Files from my external hard drive are no longer indexed after rebooting. I have to remount and then run # updatedb after each reboot. The problem is updatedb takes a few minutes for my external hard drives. Is there any way I can retain indexing for my externals after I reboot so that the locate command can search through my externals? EDIT: Per Request here are my specs: $ cat /etc/updatedb.conf PRUNE_BIND_MOUNTS="yes" # PRUNENAMES=".git .bzr .hg .svn" PRUNEPATHS="/tmp /var/spool /media" PRUNEFS="NFS nfs nfs4 rpc_pipefs afs binfmt_misc proc smbfs autofs iso9660 ncpfs coda devpts ftpfs devfs mfs shfs sysfs cifs lustre_lite tmpfs usbfs udf fuse.glusterfs fuse.sshfs ecryptfs fusesmb devtmpfs" # mount /dev/sda5 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/me/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=me) /dev/sdb1 on /media/me type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) /dev/sdd1 on /media/Little Boy type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) /dev/sde1 on /media/Fat Man type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) # on_ac_power; echo $? 255
