• How does ecryptfs impact harddisk performance?

  - by Freddi

  I have my home directy encrypted with ecryptfs. Does ecryptfs lead to fragmentation? I have the feeling that reading files, displaying folders and login became continuously slower and slower (although it was not noticeably slow at the beginning). The hard disk makes a lot of seek noise even if I open only a text file. In /home/.ecryptfs I see many big archives (that probably contain the encrypted files), so I'm wondering if Linux file system online defragmentation gains anything here. What options do I have to increase performance? Should I decide whether I maybe better do without encryption?

• OpenGL 3.0+ framebuffer to texture/images

  - by user827992

  I need a way to capture what is rendered on screen, i have read about glReadPixels but it looks really slow. Can you suggest a more efficient or just an alternative way for just copying what is rendered by OpenGL 3.0+ to the local RAM and in general to output this in a image or in a data stream? How i can achieve the same goal with OpenGL ES 2.0 ? EDIT: i just forgot: with this OpenGL functions how i can be sure that I'm actually reading a complete frame, meaning that there is no overlapping between 2 frames or any nasty side effect I'm actually reading the frame that comes right next to the previous one so i do not lose frames

• Could Ajax + Caching be seen as cloaking?

  - by Angel

  I have a website where we use a technique to speed up loading times based in a combination of AJAX + caching. Basically, when we have a section in a page with content which is slow to retrieve, we first look if it's cached. If it is, then we serve the content, if it's not, we serve a placeholder and then make an AJAX call in the client to retrieve the content, wich is now cached for subsequent requests. As a consecuence, sometimes you get the entire page content in the first request, and sometimes you get those placeholders, wich get filled inmediatly with the responses of the AJAX request. You can see an example in the results count by category in the right column of this page: http://www.inzoco.com/crits/2-1-3-28-185-0-28079-0-0/listado-piso-en-alquiler-en-madrid-madrid.aspx I'm worried if it could be seen as cloaking by search engines because if you make a request for a page wich content isn't cached and then ask again for the same page, you would get different responses, the first with the placeholders and AJAX requests and the second one with al the content rendered.

• Can you over-normalize?

  - by drsql

  Now, don’t get too excited and grab your pitchforks and torches. Clearly, it is extremely possible to overdo something in the design, but very often normalization takes the rap as being the culprit. In my “Database Design Fundamentals” presentation, one of my favorite things to do is ask “What is the most important normal form?” 9 out of 10 times, someone answers “Third”. When I ask what they have against fourth, the usually say that it makes the database work too slow. But when they find out that...(read more)

• Disk failing on dell mini, are there diagnostic tools?

  - by John Lawrence Aspden

  Hi, my dell mini 10v running Ubuntu 10.10 runs ok for hours, but then will suddenly slow down drastically. Switching to a console shows lots of error messages, which also get into /var/log/syslog. These errors happen every couple of seconds. I'm figuring that the disk is failing, but is there anyway to be sure, and can laptop disks be replaced easily?

• Temporarily share/deploy a python (flask) application

  - by Jeff

  Goal Temporarily (1 month?) deploy/share a python (flask) web app without expensive/complex hosting. More info I've developed a basic mobile web app for the non-profit I work for. It's written in python and uses flask as its framework. I'd like to share this with other employees and beta testers (<25 people). Ideally, I could get some sort of simple hosting space/service and push regular updates to it while we test and iterate on this app. Think something along the lines of dropbox, which of course would not work for this purpose. We do have a website, and hosting services for it, but I'm concerned about using this resource as our website is mission critical and this app is very much pre-alpha at this point. Options I've researched / considered Self host from local machine/network (slow, unreliable) Purchase hosting space (with limited non-profit resources, I'm concerned this is overkill) Using our current web server / hosting (not appropriate for testing) Thanks very much for your time!

• Ubuntu DVD for Africa

  - by Brendon

  I live in Tanzania Africa and have been promoting Ubuntu for use by NGOs, Schools, and Friends. So far I've got a lot of positive feedback, but do have one huge problem. Internet here is both slow and very costly (up to $1,200 per month) So what I am looking for is a current release of Ubuntu which includes all the updates and popular applications already on it like; Gimp, VLC, Ubuntu Restricted files, Scribus, Inkscape, VirtualBox, Chrome, Audacity, Compiz, Blender, Ubuntu Tweak, Gnucash, Skype, etc... Basically all the 4 - 5 star applications. Does a hybrid DVD exist? I found links to one called Ubuntu Install Box 11.04, but not sure if they are truly legitimate. Any help would be greatly appreciated. Brendon

• Advanced Search Stored procedure

  - by Ray Eatmon

  So I am working on an MVC ASP.NET web application which centers around lots of data and data manipulation. PROBLEM OVERVIEW: We have an advanced search with 25 different filter criteria. I am using a stored procedure for this search. The stored procedure takes in parameters, filter for specific objects, and calculates return data from those objects. It queries large tables 14 millions records on some table, filtering and temp tables helped alleviate some of the bottle necks for those queries. ISSUE: The stored procedure used to take 1 min to run, which creates a timeout returning 0 results to the browser. I rewrote the procedure and got it down to 21 secs so the timeout does not occur. This ONLY occurs this slow the FIRST time the search is run, after that it takes like 5 secs. I am wondering should I take a different approach to this problem, should I worry about this type of performance issue if it does not timeout?

• Tester that doesn't test

  - by George

  What should I do about a tester that does not test? We have a complicated dry run scenario, that takes a lot of time to execute. Mostly this tester will execute it's tests in very slow way...checking emails, internet, etc. He reports just a few bugs, but! Whenever the official dry-run begins (these are logged with testlink) the tester starts to open new bugs that where not discovered before. Is he not doing his job correctly? Or am I just overlooking how tests work? I'm not his supervisor, but he is testing code that I wrote.

• High CPU load - Ubuntu 14.04

  - by watt

  I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

• how to preload more than one but not all images of a slideshow with jquery

  - by wtip

  I'd like to create a web based stop motion video player. Basically a slideshow that shows 2-4 images per second. Each image might be a maximum of 20KB. I don't want to preload all images in the slideshow as there might be thousands, however I need to preload more than just the next image in the show as this will not playback fast enough (because of the playback speed the browser needs to be loading more than one image at a time). I've been looking at using the jQuery Cycle Plugin (http://malsup.com/jquery/cycle/) with a addSlide type function but don't know how to make it work. Would something like this might work? -Slideshow starts -image is played back -preloader will attempt to load up to the next 60 images -playback will wait for the next image in line to completely load, but will not wait for all 59 others. The playback / preloading order is important for this application.

• Activity log manager is not preventing Zeitgeist from logging files

  - by Vivek

  I am running Gnome Shell and I do not like Zeitgeist indexing all my files. This makes the search in dash very slow. I do not want the dash to search recent files, so I installed activity log manager to prevent zeitgeist's logging activity. I configured the log manager as below. But even after adding every folder, the files keep appearing in the dash under Recent Items. Is there any other software or tweak which will instruct zeitgeist to search only applications installed in my system and not my recent files.

• Swipe gestures on Android ListView items

  - by Bartek

  I have a ListView populated by a ResourceCursorAdapter. I use the loaders mechanism to query a ContentProvider for list items. I detect swipe gestures on the list items to perform some actions on them. New items get added by a background service, so the list can change dynamically. Everything works fine, except when I start swiping and a database change occurs (as a result of the background service adding a new row). In such case the gesture is not detected properly. I noticed that ACTION_CANCEL is dispatched to the list item view and also that bindView is executed for all visible items. Inside the bindView method I only set some text - I don't change any listeners there. How can I make gestures work even when new items are being added by the background service? Perhaps there's a way to prevent the motion from being cancelled or I can pause database updates so they don't interrupt the gesture.

• Redehost Transforms Cloud & Hosting Services with MySQL Enterprise Edition

  - by Mat Keep

  RedeHost are one of Brazil's largest cloud computing and web hosting providers, with more than 60,000 customers and 52,000 web sites running on its infrastructure. As the company grew, Redehost needed to automate operations, such as system monitoring, making the operations team more proactive in solving problems. Redehost also sought to improve server uptime, robustness, and availability, especially during backup windows, when performance would often dip. To address the needs of the business, Redehost migrated from the community edition of MySQL to MySQL Enterprise Edition, which has delivered a host of benefits: - Pro-active database management and monitoring using MySQL Enterprise Monitor, enabling Redehost to fulfil customer SLAs. Using the Query Analyzer, Redehost were able to more rapidly identify slow queries, improving customer support - Quadrupled backup speed with MySQL Enterprise Backup, leading to faster data recovery and improved system availability - Reduced DBA overhead by 50% due to the improved support capabilities offered by MySQL Enterprise Edition. - Enabled infrastructure consolidation, avoiding unnecessary energy costs and premature hardware acquisition You can learn more from the full Redehost Case Study Also, take a look at the recently updated MySQL in the Cloud whitepaper for the latest developments that are making it even simpler and more efficient to develop and deploy new services with MySQL in the cloud

• Forward Mysql logs to Syslog-ng

  Ubuntu 10.04 I have set MySQL to log slow queries and a general mysql log. How can I pipe those files in syslog to forward to centralized logging service (which is working)? Tried: source s_mysql_instance_1 { pipe("/var/log/mysql/mysql.log" ); }; log { source(s_mysql_instance_1); destination(d_loggly); }; Get: Error opening file for reading; filename='/var/log/mysql/mysql.log', error='Permission denied (13)' Error initializing source driver; source='s_mysql_instance_1', id='s_mysql_instance_1#0' Error initializing message pipeline; I have also disabled apparmor and still get the same results

• Can Unity be uninstalled?

  - by Dave M G

  Recently when doing an update, I noticed I was downloading a bunch of packages related to Unity. I use Gnome-Classic, and have no intention of ever using Unity. So, I thought I might save myself some bandwidth and download times (which can be slow on my laptop) by removing Unity. However, on next reboot, I could not get any form of GUI interface. Only by reinstalling Unity was I able to get the log in interface and get back into Gnome Classic. Can I get rid of Unity, or is it somehow now integral to Ubuntu in a way that makes Ubuntu not run without it (even if I'm exlusively using Gnome-Classic)?

• Thumbnailers of text and ogg files

  - by David López

  I use ubuntu 12.04 and I can see in nautilus thumbnailers of ogg (with embedded artwork) and text files, just like in figure It's a nice feature. I have a slow machine and I've installed Arch with LXDE and pcmanfm. I would like the same thumbnailers, but I can only see a few of them like in the figure I've installed nautilus, thunar, spacefm... and lots of different thumbnailers in my Arch machine, but I haven't be able to see the thumbnailers of text and ogg files. I think that maybe ubuntu uses a patched nautilus version with extended capabilities or something like this. Any idea? Thanks.

• Is it necessary to read every single byte to check if a copied file is identical to the original?

  - by Koen027

  I recently learned of a program called Total Commander. It's a Windows Explorer replacement and has its own stuff to copy files. To check whether the files are identical, instead of calculation a CRC, it literally checks every single byte, one at a time, on both the original and the copy. My question is: Is this necessary? Can CRC or any other such technique go wrong? Should you, as a programmer, try and implement this perfect but slow system, or is it too extreme?

• How can I generate a 2d navigation mesh in a dynamic environment at runtime?

  - by Stephen

  So I've grasped how to use A* for path-finding, and I am able to use it on a grid. However, my game world is huge and I have many enemies moving toward the player, which is a moving target, so a grid system is too slow for path-finding. I need to simplify my node graph by using a navigational mesh. I grasp the concept of "how" a mesh works (finding a path through nodes on the vertices and/or the centers of the edges of polygons). My game uses dynamic obstacles that are procedurally generated at run-time. I can't quite wrap my head around how to take a plane that has multiple obstacles in it and programatically divide the walkable area up into polygons for the navigation mesh, like the following image. Where do I start? How do I know when a segment of walk-able area is already defined, or worse, when I realize I need to subdivide a previously defined walk-able area as the algorithm "walks" through the map? I'm using javascript in nodejs, if it matters.

• Good php editor

  - by Web Developer

  i have seen through other questions on the topic but most are a bit old. I looking for a good editor for developing on PHP in Linux(ubuntu). Here is my requirements Basic editor features Free Light-Weight Syntax highlighting Code Folding (class,function,if/else/while/foreach block) Code completion Invalid Syntax/Error highlighting as you type Auto code intending Snippet support(pieces of custom or language specific codes that i can insert) Extendable support It would be great if it had the following Debugging support WYSIWYG Code formatting Framework support(cakephp/yii/zend/smarty) Testing support Todo Native look and feel(Gnome) Flex/ROR support is welcome but not a requirement Mysql support I have tried the following editors Netbeans - it bloated, resource hogging and doesnt not have a native look and feel. Eclipse is okay but i cant fold if/while blocks and slow. Gedit can be extended and i have tried it but still i could not fold code or show error. I currently use Geany but it doesn't inform me of syntax errors as i type. If you have ways to solve the problems with above editors they too are also welcome

• How should I replan A*?

  - by Gregory Weir

  I've got a pathfinding boss enemy that seeks the player using the A* algorithm. It's a pretty complex environment, and I'm doing it in Flash, so the search can get a bit slow when it's searching over long distances. If the player was stationary, I could just search once, but at the moment I'm searching every frame. This takes long enough that my framerate is suffering. What's the usual solution to this? Is there a way to "replan" A* without redoing the entire search? Should I just search a little less often (every half-second or second) and accept that there will be a little inaccuracy in the path?

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank
