  • Apache expands REQUEST_FILENAME with filetype

    - by Lauer
    I have a .htaccess fil on a Apache22 server. RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.+)$ /index.php?p=$1 [L] The idea is when the request is /testpage it should be rewritten to /index.php?p=testpage. The problem is that apache does a write before my file, so the actually request is testpage.xml which actually does exists. Therefore, the first RewriteCond is newer true, and my rewrite rule is never applied on the /testpage request. There server should be a standard setup on a FreeBSD server. I know this work on other servers.

  • Gnome keyboard shortcuts dysfunctional after waking up from sleep

    - by dennis2008
    Hello, I am using Ubuntu 9.10 on my Thinkpad T61. Very often after the system woke up from sleep, all the gnome shortcuts went dead (no effect when key combinations pressed). Things like "Alt+F4, Alt+TAB" are dead; things like Ctrl+C/Ctrl+V are OK; buttons such as volume up/down also OK; I tried to Google for answers but wasn't lucky enough. Any idea how to solve it? Thanks! If it's not preventable, can I at least restore them without restarting the session?

  • 3 Root accounts in MySQl database

    - by hairbymaurice
    Hello, I have managed to get mySQL running under Ubuntu 8.10, I am now diligently trying to secure the database and am adding passwords for the root users. My question: I have a root user under the host "kickseed" with no password set I have no idea what kickseed is as the database is installed under localhost, on searching around i have discovered that this is something to do with the ubuntu OS itself. Is it safe to delete this user account from MySQL or is it used for something by the OS? If i need to keep it should i /can i protect it with a password? Also i have another root account under the host IP 127.0.0.1 again can i delete this? My absolute preference would be to have only one account with root access but i do not want to delete these accounts if they are necessary. Thanks for tolerating a newbie Regards Hairby

  • Will you choose JavaFX for Development?

    - by javafx4you
    A few weeks ago, a poll on the home page of java.net caught my eyes, because it was related to JavaFX. Its title: Will you use JavaFX for development once it's fully ported to Mac and Linux platforms? Usually, the results for this type of polls are published on the editor's Daily Blog soon after the poll closes. For some reason, this didn't happen for the JavaFX poll, so I'll take a shot at interpreting the results.  The results found on java.net look pretty close to the following: Although this way to look at the results already gives us an idea of how much traction JavaFX is getting, there are just too many type of answers that make it hard to read. The answers "maybe" and "I don't know" are awfully similar, so I'm tempted to collapse these together. Then there is "No, I don't do that type of development" that just doesn't belong here, as obviously developers who ave chosen this answer don't develop Rich Internet Apps, and therefore I will adapt the % results accordingly. Finally, I've been tempted to combine the top three categories just t simplify the results. This gives me the following chart:  Whether you prefer the original graph, or my simplified take on it, one thing is sure:  less than 10% of developers who have taken this poll plan to stick to another toolkit (presumably Swing or SWT), while the vast majority is inclined to use JavaFX. When you take into account that JavaFX 2.0 is pretty much a "new" API (no more JavaFX Script), I think these are some pretty good results, 6 months after the official release of JavaFX 2.0.

  • Offset AND incremental backup

    - by Pyrolistical
    I already do backups from my main computer to my server computer using synctoy. But now I also want to do off-site backup. My idea so far: have source hard drive (we'll call S) at home have backup hard drive at work called B have transport hard drive called T connect T at work and record index of files on B take T home and check index of S and note new/changed/deleted files and copy changed files to T take T to work and update S repeat Its basically a sneakernet and using all of the advantages of it. High bandwidth, low latency. Is there some software to do this, or do I have to write it myself?

  • DD-WRT Router Can't hold a connection after initial setup...

    - by AC
    Struggeling with my new DDWRT router (Buffalo WZR-HP-G300NH) configuration. I configured it using one machine while comparing the settings on my existing Linksys WRT54GL on another machine. To the best of my knowledge, I've set it up the same way as my Linksys, but DDWRT has so many other options. After configuring it, I plugged it into the modem, VOIP device & my network. I see the phones come back online. However after a few minutes, it seems I lose the outbound connection (phones die and I can't get out over HTTP). What's confusing me is it works for a few minutes, then it fails. No idea what to look for. Ideas?

  • How to set up Drupal Plugin Manager on MAMP in a secure way?

    - by Andrei
    Hi, I use MAMP PRO as global webserver. First of all, is it a good idea? Secondly, my objective is to run a Drupal website with as easy management as possible. Now I want to use Plugin Manager module to install additional modules and themes for my website. It wants to use ftp for that, and I know that if I open access to FTP port then IT-department guys will come to me and ask to shut it down. So I wonder if there is a way to allow Plugin Manager to install modules, having the port 21 closed somehow?

  • How do I estimate the number of RSS subscribers?

    - by Robert Kosara
    I'm running a website, and would like to get a better idea how many subscribers I have. I can check the number of subscribers on Google Reader for my two feeds (RSS and Atom). I also have access to my server logs, so I sometimes collect all the IP addresses that access the feeds over a month or so and do a uniq. Is that an accurate way of doing this? Are there other feed aggregators that I need to take into account? Any pitfalls when just going by IP address? I've also thought about embedding an image in the feeds to get a better count. But do all feed readers load images automatically?

  • Ethernet 802.1x client -> WiFi AP on a Raspberry Pi?

    - by Martin Janiczek
    I have an Ethernet connection that requires 802.1x authentication (TTLS, MSCHAPv2, name+password). My goal is to connect that to something that would then act as an WiFi AP, so I can use the connection on more devices (iPhone, notebook, etc.) Would it be possible/good idea to use Raspberry Pi for this purpose? Or are there better-suited devices to do this? EDIT: found some alternatives but because of low rep can't post more than two links...

  • How to install PyQt on Mac OS X 10.6

    - by Albert
    I want to install PyQt. This seems kind of complicated to install on OS X. I haven't found any precompiled packages of it (are there any? I would really prefer those). So I downloaded PyQt. And SIP, because it depends on that. These files: http://www.riverbankcomputing.co.uk/static/Downloads/PyQt4/PyQt-mac-gpl-4.7.3.tar.gz http://www.riverbankcomputing.co.uk/static/Downloads/sip4/sip-4.10.2.tar.gz Did a python configure.py && make && sudo make install on SIP -- installed without any problems. Tried the same on PyQt -- and failed of course: /Library/Frameworks/QtCore.framework/Headers/qglobal.h:288:2: error: #error "You are building a 64-bit application, but using a 32-bit version of Qt. Check your build configuration." Ok, so I tried with python configure.py --use-arch=i386. Same error. Any idea?

  • Trying to get a new user up on VPN

    - by Chris
    Caveat: I am not a sysadmin, so please forgive the n00bness of the query. We have a new user and I'm trying to get them up on VPN. We use pfsense as an IPSEC endpoint. This person is using Shrewsoft for the client. I had created an entry in pfsense for them and then edited a previous user's config file. Shrewsoft didn't import the config file very well and I had to hand edit the information. Now we are getting gateway errors. One thing I've noticed is that there is a different between the values of the preshared key stored on the firewall and the psk stored in the config file. I assume it has something to do with a hash, but I've no idea if that's the case and whether that might be what's causing the problem. Any suggestions greatly appreciated! Tangentially, is there some software used to generate these config files?

  • Macbook superdrive got calibration problems

    - by Fractal
    I have an intel macbook dual 2Ghz, bought about three years ago. I've had some problems with the superdrive and changed it a year and a half ago. the drive is Matshita DVD-R UJ 857 now I'm into burning cd's again and try to burn a DVD with Toast Titanium from an .iso on my hard drive But it won't work. When I launch the burn, the disc suddenly stops turning, and an error log pops: medium error, sense code = 0x73, 0x03 then I try with the built in cd burner of the macbook as soon as I click burn, the cd stops turning in the drive, and error log says peripheral couldn't calibrate power of the laser required for medium so since I'm not that logical of a geek, I try my first idea: let's see with other brands of DVD! the problem is that it works, now. but I'd like for all of my medium to be usable, and I've already seen my ridata DVD being burn, so here's the question. What the hell is happening with my superdrive? :)

  • How can I get data off of a damaged thumb drive?

    - by Lord Torgamus
    A guy I work with just came by to ask me about a damaged thumb drive/USB flash drive. Apparently his son dropped it on a hard surface and it won't power up anymore. They've tried plugging it into multiple machines without success, even though each port they tried was able to power other USB devices. He knows it's not a lost cause because a local tech store is offering to recover the data for $500, but he says they're not worth that much. I figured someone on SU would have an idea about this; he doesn't care about using the drive in the future, just wants to salvage a few files that would be a pain to recreate. Is this possible without advanced equipment, and if so, how? He said he already tried the advice on the Internet about typing in different drive letters and such, but that failed because there was no power going to the drive. He also said that he opened the case up at one point, but I'm not sure what, if anything, he did inside.

  • Is there an idiot's guide to software licensing somewhere?

    - by Karpie
    Basically, my knowledge on the issue is zilch other than the fact that open-source and closed-source exists. I'm a web developer (not a designer in the slightest), so I look online for things like icons. I've always been a big fan of these icons, which have a Creative Commons Attribution 2.5 License. As far as I can see, this license says 'do whatever you want with them as long as you have a link back to me somewhere'. Is that assumption correct? Just today I found a new icon set, with a much more confusing license (found here), and to be quite honest I have no idea if I'm allowed to use them or not. At the moment I want to just use them for toy stuff that might never see the light of day, but then my source code is stored on Github, is it legal to store the icons there where they're publicly accessible? If I put them on my personal website that might have ads on it to make me five cents every now and then, is that legal? If I use them on a site that offers a free service to users, is that legal? If that site then starts making money (via things like paid subscriptions) or gets bought out by someone (highly unlikely but one day possible) is that legal? Is there some noob guide out there that explains all this stuff, because I would hate to start using this sort of stuff now only to have to change it all later. Even if I buy the icons, there's still licensing issues that I don't understand! :( And this sort of stuff keeps popping up more and more often...

  • Hash Algorithm Randomness Visualization

    - by clstroud
    I'm curious if anyone here has any idea how the images were generated as shown in this response: Which hashing algorithm is best for uniqueness and speed? Ian posted a very well-received response but I can't seem to understand how he went about making the images. I hate to make a new question dedicated to this, but I can't find any means to ask him more directly. On the other hand, perhaps someone has an alternative perspective. The best I can personally come up with would be to have it almost like a bar graph, which would illustrate how evenly the buckets of the hash table are being generated. I have a working Cocoa program that does this, but it can't generate anything like what he showed there. So the question is two fold I suppose: A) How does one truly interpret the data he shows? Is it more than "less whitespace = better"? B) How does one generate such an image based on some set of inputs, a hash, and an index? Perhaps I'm misunderstanding entirely, but I really would like to know more about this particular visualization technique. Or maybe I'm mis-applying this to hash tables rather than just hashes in general, but in that case I don't know how it would be "bounded" for the image.

  • Flash Media Server slow over SSL

    - by Antilogic
    We are using FMS to host a VoD site. We host FMS internally (we do not use a CDN). We recently installed an SSL certificate to alleviate connection issues for clients (they're networks either block or don't support RTMP), however we're noticing that when streaming in RTMPS connections are drastically slower (on the order of Mbps). I know SSL causes some amount of over head but both client and server show almost no signs of exertion. Speedtest.net and a locally hosted speed test confirm that bandwidth is not an issue. I'm really not a network guru, so I'm at a loss as to where to check next. Do any of you have an idea why streaming media would run so slow over SSL?

  • C++: calling non-member functions with the same syntax of member ones

    - by peoro
    One thing I'd like to do in C++ is to call non-member functions with the same syntax you call member functions: class A { }; void f( A & this ) { /* ... */ } // ... A a; a.f(); // this is the same as f(a); Of course this could only work as long as f is not virtual (since it cannot appear in A's virtual table. f doesn't need to access A's non-public members. f doesn't conflict with a function declared in A (A::f). I'd like such a syntax because in my opinion it would be quite comfortable and would push good habits: calling str.strip() on a std::string (where strip is a function defined by the user) would sound a lot better than calling strip( str );. most of the times (always?) classes provide some member functions which don't require to be member (ie: are not virtual and don't use non-public members). This breaks encapsulation, but is the most practical thing to do (due to point 1). My question here is: what do you think of such feature? Do you think it would be something nice, or something that would introduce more issues than the ones it aims to solve? Could it make sense to propose such a feature to the next standard (the one after C++0x)? Of course this is just a brief description of this idea; it is not complete; we'd probably need to explicitly mark a function with a special keyword to let it work like this and many other stuff.

  • Game Messaging System Design

    - by you786
    I'm making a simple game, and have decided to try to implement a messaging system. The system basically looks like this: Entity generates message - message is posted to global message queue - messageManager notifies every object of the new message through onMessageReceived(Message msg) - if object wants, it acts on the message. The way I'm making message objects is like this: //base message class, never actually instantiated abstract class Message{ Entity sender; } PlayerDiedMessage extends Message{ int livesLeft; } Now my SoundManagerEntity can do something like this in its onMessageReceived() method public void messageReceived(Message msg){ if(msg instanceof PlayerDiedMessage){ PlayerDiedMessage diedMessage = (PlayerDiedMessage) msg; if(diedMessage.livesLeft == 0) playSound(SOUND_DEATH); } } The pros to this approach: Very simple and easy to implement The message can contain as much as information as you want, because you can just create a new Message subclass that has whatever info necessary. The cons: I can't figure out how I can recycle Message objects to a object pool, unless I have a different pool for each subclass of Message. So I have lots and lots of object creation/memory allocation over time. Can't send a message to a specific recipient, but I haven't needed that yet in my game so I don't mind it too much. What am I missing here? There must be a better implementation or some idea that I'm missing.

  • Collision detection between a sprite and rectangle in canvas

    - by Andy
    I'm building a Javascript + canvas game which is essentially a platformer. I have the player all set up and he's running, jumping and falling, but I'm having trouble with the collision detection between the player and blocks (the blocks will essentially be the platforms that the player moves on). The blocks are stored in an array like this: var blockList = [[50, 400, 100, 100]]; And drawn to the canvas using this: this.draw = function() { c.fillRect(blockList[0][0], blockList[0][1], 100, 100); } I'm checking for collisions using something along these lines in the player object: this.update = function() { // Check for collitions with blocks for(var i = 0; i < blockList.length; i++) { if((player.xpos + 34) > blockList[i][0] && player.ypos > blockList[i][1]) { player.xpos = blockList[i][0] - 28; return false; } } // Other code to move the player based on keyboard input etc } The idea is if the player will collide with a block in the next game update (the game uses a main loop running at 60Htz), the function will return false and exit, thus meaning the player won't move. Unfortunately, that only works when the player hits the left side of the block, and I can't work out how to make it so the player stops if it hits any side of the block. I have the properties player.xpos and player.ypos to help here.

  • Poor CPU usage under Ubuntu

    - by remek
    Hello, I just upgraded from Ubuntu 9.10 to Ubuntu 10.04 and I am now experiencing a strange problem. My computer has a quad-core processor, and when I am running several processes simultaneously, none of the cores is fully used. Before the upgrade, when I was running 4 processes, each of them was using 100% CPU (I could see that with the 'top' command). But now, CPU usage oscillates and is always pretty low. Has anybody an idea about this problem? Is it due to Ubuntu or to the program I am running? Thank you very much in advance for your help! Best, remek

  • What's the deal with NTFS tags in windows 7

    - by polarix
    So back in the days of 'longhorn' there was this WinFS idea which was both cool looking and scary looking. Then it seemed to disappear, but we were told that many of the concepts would be rolled into Vista. Then maybe Win7. Anyway, nowadays if you look at a win7 Explorer window, you can have columns that have a lot of tag-based info about a file (right click on column header-more...), including one called "tags". Is this something in NTFS that can be modified per-file somehow? Is its GUI hiding, or is this something that's infinitely-delayed, or is it just a figment of my imagination? Sure would be nice to be able to get around the NTFS path 256 character limit for searches, and to filter file folders per Excel 2007.

  • Antenna Aligner part 1: In the beginning.

    - by Chris George
    Picture the scene, it's 9pm, I'm in my caravan (yes I know, I've heard all the jokes!) with my family and I'm trying to tune the tv by moving the aerial, retuning, moving the aerial again, retuning... 45 mins and much cursing later I succeed. Surely there must be an easier way than this? Aha, an app; there must be an app for that? So I search in the AppStore for such an app, but curiously drew a blank. Then the seeds of the idea started to grow. I can code, I work in a software house with lots of very clever people, surely I can make an app that points to the nearest digital tv transmitter! Not having looked into app development before, I investigated how one goes about making an iPhone app and was quickly greeted by a now familiar answer "Buy a mac!". That was not an option for many reasons, mostly wife related! My dreams were starting to fade until one of my colleagues pointed out that within Red Gate, the very company I work for, there was on-going development on a piece of software that would allow me to write an app using Visual Studio on a Windows machine, Nomad! Once I signed up for the beta program I got to work learning the Jquery mobile / Phonegap framework. Within a couple of hours I had written (in Visual Studio), built in the cloud (using Nomad) and published (via TestFlight) my first iPhone app onto my iPhone ! It didn't do much, but it was a step in the right direction. To be continued...

  • Intuitive view of what's using the hard drive so much on Windows 7?

    - by Aren Cambre
    Sometimes my hard drive usage is near 100%, and I have no idea what is causing it. Are there any utilities that can help diagnose excessive hard drive usage and have as intuitive of an interface as Task Manager's Processes tab, which I can sort by CPU usage? I am aware of using procmon, of adding columns to Task Manager's Processes tab like I/O Read Bytes and I/O Write Bytes, and using Resource Monitor's Disk tab. Too often, these don't give me useful information or clearly identify a single process that is hogging the disk.

  • How to fix Windows XP from muting sounds on every startup?

    - by Rookie
    This started to happen few days ago: Every time I start up my computer, the global sound volume ("Playback") is set to muted (from the checkbox), in the sound control panel. So I have to open the control panel every time i start up my computer, and click that checkbox. I have got this bug before, long time ago. I have no idea why is this happening. Any ideas how to fix this or what is causing it? I have SP 3 and most updates installed a half year ago or less.
