  • Receiving "May not have permission to edit" warning, even though I have permissions

    - by Choy
    I'm using Panic Transmit as an FTP client connecting to an Ubuntu 12.x server. When I try to edit and upload a file using it, I receive the warning that tells me to check my permissions as I may not have permissions to edit a file. I'm not setting the permissions on upload and I do have permission to edit files. After clearing the warning and checking the file on the server, may changes go through. The files I'm trying to edit are set to 775 and are part of the www-data group which my user is part of as well. Any idea why I would be getting such a prompt? This only happens on some files, not all.

  • How do i use a USB wifi device properly?

    - by acidzombie24
    I'll just say a few random things One usb wifi device i notice only worked when it plugged into my usb hub Another one worked but couldnt get full speed. It came with an extention cord and when i had it a few feet away i was able to (usually) get full speed I had a wifi card in a tower in the past and just about all laptops have it built in How do i use a USB wifi adapter properly? The first device didnt come with an extention cord and made no mention of bringing it away from the computer. When someone else tested the device he said he was getting full speed while it was plugged into his tower so i was pretty surpised. How do i use USB wifi devices properly?

  • Windows Azure Upgrade Domain

    - by kaleidoscope
    Windows Azure automatically divides your role instances into some “logical” domains called upgrade domains. During upgrade, Azure is updating these domains one by one. This is a by design behavior to avoid nasty situations. Some of the last feature additions and enhancements on the platform was the ability to notify your role instances in case of “environment” changes, like adding or removing being most common. In such case, all your roles get a notification of this change. Imagine if you had 50 or 60 role instances, getting notified all at once and start doing various actions to react to this change. It will be a complete disaster for your service. The way to address this problem is upgrade domains. During upgrade Windows Azure updates them one by one and only the associated role instances to a specific domain get notified of the changes taking place. Only a small number of your role instances will get notified, react and the rest will remain intact providing a seamless upgrade experience and no service disruption or downtime. http://www.kefalidis.me/archive/2009/11/27/windows-azure-ndash-what-is-an-upgrade-domain.aspx   Lokesh, M

  • FTP transfer hangs for random files

    - by hoffmandirt
    I've been stuck on this FTP issue for a while now. I have IIS 7 setup with an IIS 6 FTP server running on a Windows Server 2008 box. The problem I am running into is that I can't download certain files from the FTP server, even though I uploaded those files to the FTP server. The connection times out after 120 seconds. I have used Wireshark and checked the log files. The only message I see is the timeout message. The first thing that came to my mind was permission issues, however I have probably tried every combination of permissions that I can think of, with the end goal of getting the permissions to be the same for the files that work and the files that do not work. With the list of files I have now, I can download the zip, war, and msi files, but not the txt or sql files. It almost seems like a binary thing, but I've changed my transfer mode on the FTP client and also toggled the Active/Passive options around.

  • MySQL Connect Conference: My Experience

    - by Hema Sridharan
    It was a great experience to attend the MySQL Connect Conference for the first time ever. Personally I was very much enthralled to present about "How to make MySQL Backups" besides attending different sessions to absorb more knowledge about the technical prospects of MySQL. One of the agenda items in my presentation was "MySQL Enterprise Backup" functionality and features. There were total of 40 attendees in the session, who were very much interested about the MySQL Enterprise Backup product and gave positive feedback as well as areas of improvements on our product. Some of our features brought lot of excitement and smile amongst our customers including,1. Performance improvements in MEB 3.8.02. Incremental Base option from MEB 3.7.1 where there is no need to specify the directory name of the previous backup to fetch the lsn values and instead can directly fetch from backup_history table using --incremental-base=history: last_backup3. only-innodb-with-frm option introduced in MEB 3.7 version. A true online hot backup of InnoDB tables.I also attended a session with similar topic "MEB Best Practices" conducted by Sanjay Manwani, where he double clicked all the features and best strategies of backup & restore. I also got an opportunity to attend other sessions including,* Enabling the new generation of web and cloud services with MySQL 5.6 replication* Getting the most out of MySQL with MySQL Workbench* InnoDB compression for OLTP* Scaling for the Web and Cloud with MySQL replication.Above all, had some special moments in the conference including meeting some of the executives / colleagues for the first time f2f. On a whole, the first MySQL Connect conference was a great success in terms of manifesting the features of our products, direct feedback from customer and team building.  We also had some applauding yahoo moments when Tomas Ulin announced different releases including MySQL 5.6 RC, Connector Python 1.0 and ODBC 5.2 release, MySQL Cluster 7.3, additions to MySQL Enterprise edition etc.

  • Perpendicularity of a normal and a velocity?

    - by Milo
    I'm trying to fake angular velocity on my vehicle when it hits a wall by getting the dot product of the normal of the edge the car is hitting and the vehicle's velocity: Vector2D normVel = new Vector2D(); normVel.equals(vehicle.getVelocity()); normVel.normalize(); float dot = normVel.dot(outNorm); dot = -dot; vehicle.setAngularVelocity(vehicle.getAngularVelocity() + (dot * vehicle.getVelocity().length() * 0.01f)); outNorm is the normal of the wall. The problem is it only works half the time. It seems no matter what, the car always goes clockwise. If the car should head clockwise: -------------------------------------- / / I want the angular velocity to be positive, otherwise if it needs to go CCW: -------------------------------------- \ \ Then the angular velocity should be negative... What should I change to achieve this? Thanks Hmmm... Im not sure why this is not working... for(int i = 0; i < buildings.size(); ++i) { e = buildings.get(i); ArrayList<Vector2D> colPts = vehicle.getRect().getCollsionPoints(e.getRect()); float dist = OBB2D.collisionResponse(vehicle.getRect(), e.getRect(), outNorm); for(int u = 0; u < colPts.size(); ++u) { Vector2D p = colPts.get(u).subtract(vehicle.getRect().getCenter()); vehicle.setTorque(vehicle.getTorque() + p.cross(outNorm)); }

  • Keeps "SSH timeout" error in our AWS instance- how do i diagnose?

    I am befuddled by this error. We keep failing to SSH into our AWS instance, whether it is is deployment or via console. I have tried rebooting a few times, but it does not seem to be helping.

  • Computer Science Degree or Computer Engineering Degree?

    - by Paul
    Hello everyone, I'm 23 years old living in Italy and this year I will be getting my high school diploma. I'm interested in pursuing a collage degree and work in the IT field. At the moment I'm self teaching myself Java (I also know python, html, css and mysql). I'm also learning about algorithms and OO design. I'm curious how important a college degree is for me, considering my age and if there is a big difference between computer science and computer engineer. There is a computer science university where I currently live but not a computer engineer one. For some reason universities that offer computer engineering courses are only in bigger cities such as Milan, Bologna, Roma. Cost wise, it would be cheaper for me to study near home at a computer science school. Career wise, would a computer engineering university offer me more work opportunities instead of a computer science degree ? Is it easier transiting from CS to CEN or vice-versa? I'm not exactly sure what type of job I want to pursue in the future since I'm still a bit undecided but definitely not system/network administrator, database administrator, game developer.

  • I just ordered 70/10 internet service, and need a new router I think?

    - by data_jepp
    Before I had 25/5 service and the N standard router did just fine. Now it doesn't do the job. Online speedtest reads at 82 so I have the line. But my laptop is getting less than 30 in my room. My laptop has the following WiFi card: http://www.intel.com/content/www/us/en/wireless-products/centrino-advanced-n-6205.html What is this talk about 2.4 and 5GHz? Can my laptop be connected at once over both bands? And would that let me use the full 70Mb over Wi-Fi?

  • How do I get my laptop's screen brightness settings back?

    - by Mason Wheeler
    From when I bought it up until yesterday, my laptop would dim the screen automatically if you let it sit for long enough, and then if you hit a key or moved the mouse, the brightness would jump back to what you had it at. I enjoy that behavior. It works well. Then I booted it up today, and found that now it will dim the screen automatically if you let it sit for long enough, but it doesn't restore the screen brightness. I have to do that manually, every single time, and it's getting really old really fast. It's an Alienware M17 running Windows 7 64-bit, in case that helps.

  • Can't get Intel drivers for ASUS P6T Deluxe

    - by Alex K
    Hi everybody, A few days back my Win7 Ultimate started bugging me to install the RAID drivers for my ASUS P6T Delux. Fine, I'm all for having up to date drivers even for stuff I don't use. The problem is that the drivers I download from both ASUS support site here and the ones I get directly from Intel (can't post the second link, since I have less than 10 rep, but it's the first hit for "Intel(R) Matrix Storage Manager Driver" on google) say that my system does not meet the minimum system requirements. Impossible, I would think, what with it having the X58 chipset and the Windows version is supported one. Has anyone encountered something like this before? Any clues on how to solve this would be much appreciated. Thanks!

  • Migrating from Apache2 to Lighttpd creating errors in PHP/mySQL?

    - by Jean-Philippe Murray
    Ok, I've been using basics ubuntu LAMP setups for years now, and I wanted to give lighttpd a try. My LAMP setup run in a virtual machine with scripts running just fine. So I created a new virtual machine, starting with a fresh install of ubuntu and made my setups. On this new VM, lighttpd + php works just fine. (Or at least it seems...) Problem occurs when I take the scripts from my LAMP setup and upload them to the new VM. I'm getting : Warning: mysql_real_escape_string(): Access denied for user 'www-data'@'localhost' (using password: NO) My lighttpd setup is configured as php-cgi but not my apache2 setup. Could this be the source of the problem? I think that scripts would be independent of the server configuration, so I doubt it. Also, I know that my DB connexion informations are good (as I can log in via phpmyadmin perfectly). I'm in the dark here, any pointers ? Thanks,

  • nginx 500 error instead of 404

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • Major Google not follow increase since introducing 301 to site

    - by jakob
    Recently we implemented Varnish in front of our web nodes so that the backend would get some rest from time to time. Since varnish is case sensitive and our app was not we implemented a 301 in varnish to redirect to small case. Example: You search for PlumBer StockHOLM you will get a 301 redirect to plumber stockholm and then plumber stockholm will be cached. This worked as a charm, but when checking the Google webmaster tools we suddenly got a crazy amount of Status - Not able to follow errors. As you can see in the image below: This of course stirred up some panic and I started to read up on the documentation once again. If I pressed on one of the links I got to the help section where i found this: Well this is strange, but as the day progressed more and more errors were thrown by Google. We took the decision to make varnish return 200 instead of the 301. Now when testing the links that appears in the Not able to follow section I get a 200 back. I have tested with Chrome, curl and lynx reader and everything looks ok but the amount of errors are still increasing. What is a little bit comforting is that the links that appears in the Not able to follow section are dated before the 200 change in varnish. Why do I get these errors and why do they keep increasing? Did google release something new on October 31? Maybe I do not understand the docs correctly?

  • javascript fixed timestep gameloop with requestanimation frame

    - by coffeecup
    hello i just started to read through several articles, including http://gafferongames.com/game-physics/fix-your-timestep/ ...://gamedev.stackexchange.com/questions/1589/fixed-time-step-vs-variable-time-step/ ...//dewitters.koonsolo.com/gameloop.html ...://nokarma.org/2011/02/02/javascript-game-development-the-game-loop/index.html my understanding of this is that i need the currentTime and the timeStep size and integrate all states to the next state the time which is left is then passed into the render function to do interpolation i tried to implement glenn fiedlers "the final touch", whats troubling me is that each FrameTime is about 15 (ms) and the update loop runs at about 1500 fps which seems a little bit off? heres my code this.t = 0 this.dt = 0.01 this.currTime = new Date().getTime() this.accumulator = 0.0 this.animate() animate: function(){ var newTime = new Date().getTime() , frameTime = newTime - this.currTime , alpha if ( frameTime > 0.25 ) frameTime = 0.25 this.currTime = newTime this.accumulator += frameTime while (this.accumulator >= this.dt ) { this.prev_state = this.curr_state this.update(this.t,this.dt) this.t += this.dt this.accumulator -= this.dt } alpha = this.accumulator / this.dt this.render( this.t, this.dt, alpha) requestAnimationFrame( this.animate ) } also i would like to know, are there differences between glenn fiedlers implementation and the last solution presented here ? gameloop1 gameloop2 [ sorry couldnt post more than 2 links.. ] edit : i looked into it again and adjusted the values this.currTime = new Date().getTime() this.accumulator = 0 this.p_t = 0 this.p_step = 1000/100 this.animate() animate: function(){ var newTime = new Date().getTime() , frameTime = newTime - this.currTime , alpha if(frameTime > 25) frameTime = 25 this.currTime = newTime this.accumulator += frameTime while(this.accumulator >= this.p_step){ // prevstate = currState this.update() this.p_t+=this.p_step this.accumulator -= this.p_step } alpha = this.accumulator / this.p_step this.render(alpha) requestAnimationFrame( this.animate ) now i can set the physics update rate, render runs at 60 fps and physics update at 100 fps, maybe someone could confirm this because its the first time i'm playing around with game development :-)

  • 2 ATI Radeon HD 5870 (crossfire): Intermittent loud fan and non-functioning secondary card

    - by Merritt
    Installed 2 5870s. Left off the left side panel of my case(cooler master haf x), started my computer, installed the drivers and set up the crossfire... yada yada yada... everything worked fine. Then turned off computer, put left side panel back on, turned on computer, and heard a very loud buzzing (asssuming it was a gpu fan). Checked status of cards (in Windows 7) and the secondary card did not appear. Turned off the computer, took off left side panel, jiggled power connectors into secondary card, then turned the computer back on, and it worked again. Put the panel on, turned on computer, worked. Sometime later, turned on computer, and there's that loud fan sound again. What gives?

  • Nano suddenly putting in weird characters when I type

    - by Cocorico
    I am using a shell and editing a file in nano (similar to pico). A short while ago, it started doing this thing where if I type: $query = "select" * from topics where id='' "; and then I hit Backspace and try to stick the letter 'a' into the id='' part, it changes it to: $query = "select * from koala_topics where id='a='' "; and the cursor jumps around to a few spaces before. Also if I type print At the start of a new line, and then I think "Oh I should have added a tab" and I go back and try to add a tab, it adds a tab AND 2 spaces, and if I put the cursor through the word print, it turns into printnt. Some other weird things have happened too. I uninstalled nano using yum (which is how I installed it), and then re-installed it, thinking that would get me clean preferences (in case that was the problem) but it doesn't fix it.

    Here's a chunk of the top from my server: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 18878 www-data 20 0 200m 13m 4704 S 0 0.2 0:00.07 apache2 12374 root 20 0 197m 9460 4480 S 0 0.1 21212906w apache2 9136 root 20 0 79100 3488 2716 S 0 0.0 54518724d sshd I know the TIME+ means the total CPU time the task has used since it started. But in the above output, I simply couldn't understand what 21212906w and 54518724d mean? some considerable no of processes are showing the TIME+ with w and d prefixed. What does this mean? Is the server in trouble? Just to let you know - the server uptime is 4days. EDIT: - I can guess these refer week and days. If so why is it so large considering the uptime? - The server has 8 cores.

  • Runaway version store in tempdb

    - by DavidWimbush
    Today was really a new one. I got back from a week off and found our main production server's tempdb had gone from its usual 200MB to 36GB. Ironically I spent Friday at the most excellent SQLBits VI and one of the sessions I attended was Christian Bolton talking about tempdb issues - including runaway tempdb databases. How just-in-time was that?! I looked into the file growth history and it looks like the problem started when my index maintenance job was chosen as the deadlock victim. (Funny how they almost make it sound like you've won something.) That left tempdb pretty big but for some reason it grew several more times. And since I'd left the file growth at the default 10% (aaargh!) the worse it got the worse it got. The last regrowth event was 2.6GB. Good job I've got Instant Initialization on. Since the Disk Usage report showed it was 99% unallocated I went into the Shrink Files dialogue which helpfully informed me the data file was 250MB.  I'm afraid I've got a life (allegedly) so I restarted the SQL Server service and then immediately ran a script to make the initial size bigger and change the file growth to a number of MB. The script complained that the size was smaller than the current size. Within seconds! WTF? Now I had to find out what was using so much of it. By using the DMV sys.dm_db_file_space_usage I found the problem was in the version store, and using the DMV sys.dm_db_task_space_usage and the Top Transactions by Age report I found that the culprit was a 3rd party database where I had turned on read_committed_snapshot and then not bothered to monitor things properly. Just because something has always worked before doesn't mean it will work in every future case. This application had an implicit transaction that had been running for over 2 hours.

  • Homepage 301 Redirect to SSL Homepage

    - by user33692
    I'm hoping somebody might be able to provide a bit of advice on an issue I am having. I have 1 site where we implemented a 301 redirect on the homepage from http to https. We have links on the homepage to other parts of the site that are not under SSL (in fact there is only one other page under SSL). When I go to our webmaster account I notice that we are not being provided with any webmaster information (search queries, backlinks) related to our homepage under SSL. I performed a Fetch Google on the homepage and the information it returned is: HTTP/1.1 301 Moved Permanently Date: Fri, 08 Nov 2013 17:26:24 GMT Server: Apache/2.2.16 (Debian) Location: https://mysite.com/ Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 242 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://mysite.com/">here</a>.</p> <hr> <address>Apache/2.2.16 (Debian) Server at mysite.com</address> </body></html> I am worried that the fact that Google Fetch is not getting the correct Title Tags and Meta information from our homepage and that this is hurting our search results. Additionally, I am worried that we need to do something specific with the SiteMap to ensure that Google is correctly indexing all our pages and being able to flow from the https to the http without issues. Does anybody have any advice on how we can correctly set this up or be sure that Google is fetching the correct information?

  • Stunnel delaying boot

    - by Onitlikesonic
    My stunnel implementation works fine when the network is plugged in but it takes an awful amount of time, which delays the whole boot process, when there is no network connected to the machine. As extra information: I'm using "delay=yes" I'm using an fqdn (e.g: stunnel.mydomain.com) for the connections Using ubuntu but this also happened with centos5 previously How can this be avoided or a timeout specified? edit: doing an strace as suggested by symcbean shows the following (including the last part where it hangs): [...] --- SIGCHLD (Child exited) @ 0 (0) --- rt_sigreturn(0x11) = 0 close(3) = 0 wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 6039 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7ff9ce0c79d0) = 6046 wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 6046 --- SIGCHLD (Child exited) @ 0 (0) --- rt_sigreturn(0x11) = 6046 write(1, "[Started: /etc/stunnel/stunnel.c"..., 37) = 37 write(1, "stunnel.\n", 9) = 9 exit_group(0) = ? [...] stunnel hangs in this line: wait4(-1, and when i plug in the network cable it continues to show [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 6046

  • Booting from USB on Mac Air (using setup_mac_usb_boot.sh)

    - by Mike O
    So, I've been working on this for hours and it's getting a little tiring. As some of you may know, installing Ubuntu on Macs is frequently an adventure, and I'm experiencing that right now. The part I'm hung up on at the moment is making a bootable USB. I would just use a CD, but my laptop is a MacBook Air (which doesn't have a CD drive), and I don't own an external CD drive. I initially attempted to use the command line method supplied by the Ubuntu documentation here: https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using%20USB%20Stick However, that wasn't even recognized by rEFIt even when I made a number of different modifications to the process, so I quickly decided to look elsewhere. I came across this guide: https://help.ubuntu.com/community/MacBookAir4-2#Basic_Installation_Instructions This ended up working to a large extent. If I choose the supplied grub from rEFIt, it will bring me to the Ubuntu grub, asking me to try it, install, or check the disk. And if I choose to boot Linux directly from rEFIt, it will bring me to the language selection menu. But when I make my selection from either of these menus it pauses for about ten seconds and then gives me a command line error message. It begins with kernel panic - not syncing timer doesn't work through interrupt, and then shows about eight file names. Does anyone here have any ideas as to what can be causing this? I also tried the script with both Ubuntu 11.10 (the current version when the script was written) and 12.04.
