  • Firefox bookmark with wildcard and keyword

    - by ThankYouToPositiveContributors
    In Firefox, how do I set up URL shortcuts that include a wildcard, %s? I have definitely set this up before on another computer. For example, if I wanted to view a Jira ticket, I would enter jira XXX-1234 into the address bar and it would take me to http://jira.sutureself.com:1234/browse/XXX-1234. I remember the entry added to Firefox would be http://jira.sutureself.com:1234/browse/%s, but I can't remember where I add that. EDIT I might add, I have done this without any additional addons.

  • Ubuntu 12.04: Unable to add or delete a user named 'mysql'

    - by Afaque H
    I am trying to install MySql on Ubuntu 12.04 but the installation is failing with the error: "Can't change to run as user 'mysql'. Check if the user 'mysql' exits." So I go ahead type in the command : 'cat /etc/passwd | grep mysql' and result is null. I try to add a user 'mysql' by issuing the command 'useradd mysql'/. But it fails with the message: 'useradd: user 'mysql' already exists'. When I try to delete the user 'mysql' using the command 'userdel mysql' it also fails with the message "userdel: cannot remove entry 'mysql' from /etc/passwd." Can anyone explain me what's going on and suggest a solution.

  • How can I select a default interactive console in pyDev?

    - by dorian
    Using PyDev 2.7.1 in Eclipse 3.7.2, when I hit Ctrl-Alt-Enter to open a new interactive console, I get a dialog asking me what type of console I'd like to start ("Console for currently active editor", consoles for Python, Jython, Iron Python etc.). Now this selection dialog has no default entry and keyboard selection doesn't work, meaning that I have to use my mouse every time I need a new console, which is kind of tedious. I've checked Preferences - PyPev - Interactive Console, but found no interesting options there. Is there any possibility to define a default interactive console type so that I just have to hit Return when the dialog pops up or, even better, skip this question altogether?

  • How to animate a path like it's being drawn, dot by dot? (Raphael.js)

    - by Anton
    How to animate a vector path like it's being drawn by hand? In other words, slowly show the path pixel by pixel. I'm using Raphaël.js, but if your answer is not library specific—like maybe there's some general programming pattern for doing that kind of thing (I'm fairly new to vector animation)—it's welcome! Update I know it's easy to do with straight paths, as easy as an example on that page:: path("M114 253").animate({path: "M114 253 L 234 253"}); But try to change code on that page, say, this way:: path("M114 26").animate({path: "M114 26 C 24 23 234 253 234 253"}); And you'll see what I mean. Path is certainly animated from it initial state (point "M114 26") to the end state (curve "C 24 23 234 253 234 253" starting on point "M114 26"), but not in a way specified in question, not like it's being drawn. (Sorry for not making clear from the start that I don't mean animating straight lines.) I don't see how animateAlong can do that either. It can animate an object along a path, and how can I make this path to gradually show itself while object is being animated along it?

  • How to limit TCP writes to particular size and then block untlil the data is read

    - by ustulation
    {Qt 4.7.0 , VS 2010} I have a Server written in Qt and a 3rd party client executable. Qt based server uses QTcpServer and QTcpSocket facilities (non-blocking). Going through the articles on TCP I understand the following: the original implementation of TCP mentioned the negotiable window size to be a 16-bit value, thus maximum being 65535 bytes. But implementations often used the RFC window-scale-extension that allows the sliding window size to be scalable by bit-shifting to yield a maximum of 1 gigabyte. This is implementation defined. This could have resulted in majorly different window sizes on receiver and sender end as the server uses Qt facilities without hardcoding any window size limit. Client 1st asks for all information it can based on the previous messages from the server before handling the new (accumulating) incoming messages. So at some point Server receives a lot of messages each asking for data of several MB's. This the server processes and puts it into the sender buffer. Client however is unable to handle the messages at the same pace and it seems that client’s receiver buffer is far smaller (65535 bytes maybe) than sender’s transmit window size. The messages thus get accumulated at sender’s end until the sender’s buffer is full too after which the TCP writes on sender would block. This however does not happen as sender buffer is much larger. Hence this manifests as increase in memory consumption on the sender’s end. To prevent this from happening, I used Qt’s socket’s waitForBytesWritten() with timeout set to -1 for infinite waiting period. This as I see from the behaviour blocks the thread writing TCP data until the data has actually been sensed by the receiver’s window (which will happen when earlier messages have been processed by the client at application level). This has caused memory consumption at Server end to be almost negligible. is there a better alternative to this (in Qt) if i want to restrict the memory consumption at server end to say x MB's? Also please point out if any of my understandings is incorrect.

  • MS Access 2007 end user access

    - by LtDan
    I need some good advise. I have used Access for many years and I use Sharepoint but never the two combined. My newly created Access db needs to be shared with many users across the organization. The back end is SQL and the old way to distribute the database would be placing the db on a shared drive, connecting their PC ODBC connections to the SQL db and then they would open the database and have at it. This has become the OLD way. What is the best (and simpliest) way to allow the end users to utilize a frontend for data entry/edit reporting etc. Can I create a link through SharePoint and the user just open it from there. Your good advise is greatly approciated.

  • How to deal with a Java serialized object whose package changed?

    - by Alex
    I have a Java class that is stored in an HttpSession object that's serialized and transfered between servers in a cluster environment. For the purpose of this explanation, lets call this class "Person". While in the process of improving the code, this class was moved from "com.acme.Person" to "com.acme.entity.Person". Internally, the class remains exactly the same (same fields, same methods, same everything). The problem is that we have two sets of servers running the old code and the new code at the same time. The servers with the old code have serialized HttpSession object and when the new code unserializes it, it throws a ClassNotFoundException because it can't find the old reference to com.acme.Person. At this point, it's easy to deal with this because we can just recreate the object using the new package. The problem then becomes that the HttpSession in the new servers, will serialize the object with the new reference to com.acme.entity.Person, and when this is unserialized in the servers running the old code, another exception will be thrown. At this point, we can't deal with this exception anymore. What's the best strategy to follow for this kind of cases? Is there a way to tell the new servers to serialize the object with the reference to the old package and unserialize references to the old package to the new one? How would we transition to using the new package and forgetting about the old one once all servers run the new code?

  • Windows 8: User profile service service failed the login. User Profile can not be loaded

    - by Ryanmt
    I removed accounts that were hosted on a separate drive before upgrading to windows 8 from 7 yesterday. However, now I get the User profile service service failed the login. User Profile can not be loaded. error whenever I try to access any new account. I've attempted it: from safe mode (suggestions here ) net user test \ADD Editing the permissions on the %sysdrive%\Users\Default folder to ensure it is readable Every attempt is met with the same error. Additionally, I do not see any new entries created in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList registry entry. I'm not sure I understand why a failed user creation wouldn't trigger an error... but that seems to be what is happening here.

  • Read in double type from txt file - C++

    - by Greenhouse Gases
    Hi there I'm in the midst of a university project and have decided to implement a method that can accept information from a text file (in this instance called "locations.txt"). input from the text file will look like this: London 345 456 Madrid 234 345 Beinjing 345 456 Frankfurt 456 567 The function looks like this currently (and you will notice I am missing the While condition to finish adding input when reaches end of text in locations.txt, i tried using eof but this didnt work?!). Also get function expects a char and so cant accept input thats a double which is what the latitude and longitude are defined as... void populateList(){ ifstream inputFile; inputFile.open ("locations.txt"); temp = new locationNode; // declare the space for a pointer item and assign a temporary pointer to it while(HASNT REACHED END OF TEXT FILE!!) { inputFile.getline(temp-nodeCityName, MAX_LENGTH); // inputFile.get(temp-nodeLati, MAX_LENGTH); // inputFile.get(temp-nodeLongi, MAX_LENGTH); temp-Next = NULL; //set to NULL as when one is added it is currently the last in the list and so can not point to the next if(start_ptr == NULL){ // if list is currently empty, start_ptr will point to this node start_ptr = temp; } else { temp2 = start_ptr; // We know this is not NULL - list not empty! while (temp2-Next != NULL) { temp2 = temp2-Next; // Move to next link in chain until reach end of list } temp2->Next = temp; } } inputFile.close(); } Any help you can provide would be most useful. If I need to provide anymore detail I will do, I'm in a bustling canteen atm and concentrating is hard!!

  • Are you able to specify a the profile you want to use in pfexec?

    - by jigjig
    Are you able to specify which profile you want to use for a given user when using pfexec who has been assigned multiple profiles? One example for this use is so that we can execute a command as a different user within the same process. In exec_attr, you are able to specify the uid/gid that will be used to execute a particular command as in the following example entry: Name Service Security:suser:cmd:::/usr/sbin/rpc.nsid:uid=0;gid=0 The above profile will use the super user (uid=0) to execute the rpc.nsid command. In user_attr, you can specify multiple profiles as below: testuser::::type=normal;profiles=Name Service Security,Object Access Management Can you then specify directly to use the Object Access Management profile to pfexec?

  • Fresh install of nginx causes browser to download index.html instead of opening it

    - by 010110110101
    When I view this in Chrome, http://localhost:90 the file is downloaded instead of displayed in Chrome. This question has been asked a lot of times on SO, but about index.php files. My problem is a plain jane HTML file, not a PHP file. That hasn't been asked yet. I was hoping the solution would be similar, but I haven't been able to figure it out. Here's my example.com.conf: server { server_name localhost; listen 90; root /var/www/example.com/html index index.html location / { try_file $uri $uri/ =404; } } My index.html file contains only two words, no markup Hello World I think it's the mime.types. The mime.types file has the entry for html in it. This is a fresh nginx install. nginx -t reports "test is successful"

  • R Tree 50,000 foot overview?

    - by roufamatic
    I'm working on a school project that involves taking a lat/long point and finding the top five closest points in a known list of places. The list is to be stored in memory, with the caveat that we must choose an "appropriate data structure" -- that is, we cannot simply store all the places in an array and compare distances one-by-one in a linear fashion. The teacher suggested grouping the place data by US State to prevent calculating the distance for places that are obviously too far away. I think I can do better. From my research online it seems like an R-Tree or one of its variants might be a neat solution. Unfortunately, that sentence is as far as I've gotten with understanding the actual technique, as the literature is simply too dense for my non-academic head. Can somebody give me a really high overview of what the process is for populating an R-Tree with lat/long data, and then traversing the tree to find those 5 nearest neighbors of a given point? Additionally the project is in C, and I don't have to reinvent the wheel on this, so if you've used an existing open source C implementation of an R Tree I'd be interested in your experiences.

  • How to convert a rectangle to TRBL CSS rect value?

    - by VLostBoy
    I'm not quite sure how to put this, but here goes... The css clip attribute is defined like so: rect(top, right, bottom, left). However, I'm exploring the use of a custom Rectangle 'class' to encapsulate some operations. The rectangle class has the attributes height, width and x, y. The x and y values are encapsulated in a Point object, and the height and width are encapsulated in a Dimension object, the rectangle being a composite of a point (its top-left location) and a dimension (width and height). So far so good. I though it would be pretty simple on the basis of having the rectangles x, y, width and height values to define the css rect attribute in terms of top, right, bottom, left, but I've become hopelessly confused- I've been googling for a while, and I can't seem to find any documentation as to what the TRBL values actually are or what they represent. For example, should I be thinking in terms of co-ordinates, in which case, surely I can describe the rectangle as a css rect using the rectangles x position for Top, x position + width for Right, the rectangles height + y for Bottom and its y position for Left... but thats a load of BS, surely? Also, surely rect is actually an inset, or have I just inverted my understanding of clip? I'd appreciate some advice. What I want to be able to do is (i) Define a rectangle using x, y, width and height (ii)Express the rectangle in TRBL form so that I can manipulate a divs clipping behaviour (iii)Change x, y, width or height and recalculate in terms of TRBL and goto (ii) I appreciate there are some other factors here, and some intermediary transforms to be done, but I've confused myself pretty badly- Can anyone give me some pointers?

  • Is there a way to receive data as unsigned char over UDP on Qt?

    - by user269037
    I need to send floating point numbers using a UDP connection to a Qt application. Now in Qt the only function available is qint64 readDatagram ( char * data, qint64 maxSize, QHostAddress * address = 0, quint16 * port = 0 ) which accepts data in the form of signed character buffer. I can convert my float into a string and send it but it will obviously not be very efficient converting a 4 byte float into a much longer sized character buffer. I got hold of these 2 functions to convert a 4 byte float into an unsinged 32 bit integer to transfer over network which works fine for a simple C++ UDP program but for Qt I need to receive the data as unsigned char. Is it possible to avoid converting the floatinf point data into a string and then sending it? uint32_t htonf(float f) { uint32_t p; uint32_t sign; if (f < 0) { sign = 1; f = -f; } else { sign = 0; } p = ((((uint32_t)f)&0x7fff)<<16) | (sign<<31); // Whole part and sign. p |= (uint32_t)(((f - (int)f) * 65536.0f))&0xffff; // Fraction. return p; } float ntohf(uint32_t p) { float f = ((p>>16)&0x7fff); // Whole part. f += (p&0xffff) / 65536.0f; // Fraction. if (((p>>31)&0x1) == 0x1) { f = -f; } // Sign bit set. return f; }

  • Migrating MachineKey from iis6 on old server to iis7 on new server

    - by MaseBase
    I am migrating our hosting environment to a totally new data center with new boxes and hardware and software... the whole deal. Our website cookies are encrypted using the machineKey, so when I make a request to my domain and point it to the new web server (by overriding the local hosts file), I get an error because the cookie cannot be decrypted, since the Machine Key is different. I'd like to avoid any problems a frequent user might have when they arrive at the new server for the first time. To the best of my knowledge, at this point I think I need to set the same MachineKey from our current servers on our new servers. This way when past visitors with a cookie arrive at our website served by the new server, the cookie will be decrypted properly with the MachineKey it was encrypted with and then log them in properly. My question is where do I find my MachineKey value (in IIS 6 win2k3 server) so I can use that value to set it statically on my new servers? I've pulled up my machine.config file, but it doesn't specify the key, it only specifies a configSection where the key can be defined. It's not in my web.config for the app or elsewhere. I did find this great article on some MachineKey and Web Garden woes (which could explain some other bugs I've been experiencing with regard to the machineKey). Update I am back to this issue and am still faced with a similar problem. I have the MachineKey auto-generated on the IIS6 server but I need to get that exact key so I can set it explicitly and not have it auto-generated anymore. Any help is appreciated...

  • Sending mail via Exchange, why am I being flagged as spam?

    - by Dan
    Exchange 2007 uses direct DNS for all outgoing mail. Mail that is sent from our public IP (1.2.3.4 - this is the IP of my mailserver) is delivered to the spam folders for providers such as Comcast and yahoo. Currently, our SPF looks like this: v=spf1 ip4:1.2.3.4 mx a:mail.domain.com ?all MX: mail.domain.com.(10) The reverse DNS entry on our ISP is mail.domain.com for our IP The banner HELO response from our server is <220 mail.domain.com Our IP address is NOT blacklisted anywhere, and the Cisco Senderbase gives us a score of Good What is the reason our mail doesn't look legit?

    - by Browser Madness
    I have never intentionally changed the size of font on latest mozilla browser install on windows machine. For example Google site is now 200% size, and I did nothing to make this happen. Whats worse is it does not change back but remembers this! Similarly other sites are too small and they remember this per site. What is going on here? I mean what nonsense! How can I undo this? And for extra points who came up with this absurd behavior at mozilla? Not making this up folks. 15.0.1 Not at all clear why it changes size or how to go back to default size for these sites Acutally it just happened again while editing this entry. Icon changes and than font size is too small.

  • Expose webservice directly to webclients or keep a thin server-side script layer in between?

    - by max
    Hi, I'm developing a REST webservice (Java, Jersey). The people I'm doing this for want to directly access the webservice via Javascript. Some instinct tells me this is not a good idea, but I cannot really explain that instinct. My natural approach would have been to have the webservice do the real logic and database access, but also have some (relatively thin) server-side script layer (e.g. in PHP). Clients would talk to the PHP layer which in turn would talk to the webservice. (The webservice would be pretty local to the apache/PHP server and implicitly trust calls from the script layer. The script layer would take care of session management.) (Btw, I am not talking about just hiding the webservice behind an Apache which simply redirects calls.) But as I find myself at a lack of words/arguments to explain my instinct, I wonder whether my instinct is right - note that while I have been developing all kinds of software in all kinds of languages and frameworks for like 17 years, this is the first time I develop a webservice. So my question is basically: what are your opinions? Are there any standard setups? Is my instinct totally wrong? Or partially? ;P Many thanks, Max PS: I might add a few bits of information about the planned usage of the whole application: will be accessed by different kinds of users, partly general public, partly privileged thus, all major OS/browser combinations can be expected as clients however, writing the client is not my responsibility will potentially have very high load/traffic logic of webservice will later be massively expanded for another product which is basically a superset of the functionality of the current project there is a significant likelihood that at some point an API should be exposed which can be used by 3rd party developers - obviously, with some restrictions at some point, the public view of the product should become accessible via smartphones, too (in other words, maybe a customized version of the site to adapt to the smaller display and different input methods)

  • Triangulation & Direct linear transform

    - by srand
    Following Hartley/Zisserman's Multiview Geometery, Algorithm 12: The optimal triangulation method (p318), I got the corresponding image points xhat1 and xhat2 (step 10). In step 11, one needs to compute the 3D point Xhat. One such method is Direct Linear Transform (DLT), mentioned in 12.2 (p312) and 4.1 (p88). The homogenous method (DLT), p312-313, states that it finds a solution as the unit singular vector corresponding to the smallest singular value of A, thus, A = [xhat1(1) * P1(3,:)' - P1(1,:)' ; xhat1(2) * P1(3,:)' - P1(2,:)' ; xhat2(1) * P2(3,:)' - P2(1,:)' ; xhat2(2) * P2(3,:)' - P2(2,:)' ]; [Ua Ea Va] = svd(A); Xhat = Va(:,end); plot3(Xhat(1),Xhat(2),Xhat(3), 'r.'); However, A is a 16x1 matrix, resulting in a Va that is 1x1. What am I doing wrong (and a fix) in getting the 3D point? For what its worth sample data: xhat1 = 1.0e+009 * 4.9973 -0.2024 0.0027 xhat2 = 1.0e+011 * 2.0729 2.6624 0.0098 P1 = 699.6674 0 392.1170 0 0 701.6136 304.0275 0 0 0 1.0000 0 P2 = 1.0e+003 * -0.7845 0.0508 -0.1592 1.8619 -0.1379 0.7338 0.1649 0.6825 -0.0006 0.0001 0.0008 0.0010 A = <- my computation 1.0e+011 * -0.0000 0 0.0500 0 0 -0.0000 -0.0020 0 -1.3369 0.2563 1.5634 2.0729 -1.7170 0.3292 2.0079 2.6624

  • Cakephp 1.3, Weird behavior on firefox when using $this->Html->link ...

    - by ion
    Greetings, I am getting a very weird and unpredictable result in firefox when using the following syntax: $this->Html->link($this->Html->div('p-cpt',$project['Project']['name']) . $this->Html->div('p-img',$this->Html->image('/img/projects/'.$project['Project']['slug'].'/project.thumb.jpg', array('alt'=>$project['Project']['name'],'width'=>100,'height'=>380))),array('controller' => 'projects', 'action' => 'view', $project['Project']['slug']),array('title' => $project['Project']['name'], 'escape' => false),false); OK I know it is big but bear with me. The point is to get the following output: <a href="x" title="x"> <div class="p-ctp">Name</div> <div class="p-img"><img src="z width="y" height="a" alt="d" /></div> </a> I'm not sure if this validates correctly both on cakephp and html but it works everywhere else apart from firefox. You can actually see the result here: http://www.gnomonconstructions.com/projects/browser To reproduce the result use the form with different categories and press search. At some point it will happen!! Although most of the time it renders the way it should, sometimes it produces an invalid output like that: <a href="x" title="x"></a> <div class="p-cpt"> <a href="x" title="x">name</a> </div> <div class="p-img"> <a href="x" title="x"><img src="x" width="x" height="x" alt="x" /></a> </div> Looks like it repeats the link inside each element. To be honest the only reason I used this syntax was because cakephp encourages it. Any help will be much appreciated :)

  • Excel Countif external date

    - by Duall
    I am making an Excel 2010 spreadsheet to log support calls, services, and installations that each member would fill out. Due to being paid by job rather than by hour, there is a need for it to count each of these ("Call", "Service", "Install") there is in any given time span. The entry of the data itself would be in Sheet 1, and then a 'splash screen' of sorts would be in Sheet 2. Here I would like to be able to put a date range and it would display how many of each there is. I already can do the COUNTIF statement, =COUNTIF(Activity!$B:$B,"Call") but I don't know how to: a) Add in the prerequisite for a date so it only gets "Calls" within a certain time frame. b) Take the date it looks for from a cell on the splash screen.

  • Proftpd: How to set default root to a users home directory without jailing the user?

    - by sacamano
    Hi there. I've installed proftpd on my debian box but I'm having having some trouble with the configuration. In my proftpd.conf I've added; DefaultRoot ~ !ftp_special This works fine in that all users except members of ftp-special are unable to navigate outside of their home folder. However, I want users that are members of ftp-special to enter a special home folder when logging on to the ftp server but at the same time I want them to be able to navigate the entire server. Right now, if a user that is a member of ftp-special logs on his entry-point is the root ( / ). Thanks in advance.
