  • Updating a Safari Extension?

    - by Ricky Romero
    Hi there, I'm writing a simple Safari Extension, and I'm trying to figure out how to get the update mechanism working. Apple's documentation here is delightfully vague: http://developer.apple.com/safari/library/documentation/Tools/Conceptual/SafariExtensionGuide/UpdatingExtensions/UpdatingExtensions.html And here's my manifest, based on that documentation: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Extension Updates</key> <array> <dict> <key>CFBundleIdentifier</key> <string>net.rickyromero.safari.shutup</string> <key>Team Identifier</key> <string>TMM5P68287</string> <key>CFBundleVersion</key> <string>1</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>URL</key> <string>http://rickyromero.net/misc/SafariExtensions/ShutUp.safariextz</string> </dict> </array> </dict> </plist> I don't know where to get "YourCertifcateID," for example. And when I increment the values for CFBundleVersion and CFBundleShortVersionString, it doesn't trigger an update. I know Safari is hitting my manifest though, because I'm watching HTTP traffic. Thoroughly stumped. Any ideas, guys?

  • How do I change my gnome Ubuntu key-binding work as emacs?

    - by Douglas
    , Hello, everyone How can I change editing key-binding in Gnome on Ubuntu, and make it work like Emacs? Eg. When I'm chat with my friend, and I want to use Ctrl-a Ctrl-k to move my cursor go to the left of current line, and then cut current line, as OSX or Emacs. By default in Gnome Ubuntu, Ctrl-a is for "select all" and ctrl-k for nothing. Where does this key binding define? And how can I change this? I tried gnome-keybinding-properties and gsettings, find nothing. Maybe I have to compile something?

  • How to put foreign key constraints on a computed fields in sql server?

    - by Asaf R
    Table A has a computed field called Computed1. It's persisted and not null. Also, it always computes to an expression which is char(50). It's also unique and has a unique key constraint on it. Table B has a field RefersToComputed1, which should refer to a valid Computed1 value. Trying to create a foreign key constraint on B's RefersToComputed1 that references A' Computed1 leads to the following error: Error SQL01268: .Net SqlClient Data Provider: Msg 1753, Level 16, State 0, Line 1 Column 'B.RefersToComputed1' is not the same length or scale as referencing column 'A.Computed1' in foreign key 'FK_B_A'. Columns participating in a foreign key relationship must be defined with the same length and scale. Q: Why is this error created? Are there special measures needed for foreign keys for computed columns, and if so what are they? Summary: The specific problem rises from computed, char based, fields being varchar. Hence, Computed1 is varchar(50) and not char(50). It's best to have a cast surrounding a computed field's expression to force it to a specific type. Credit goes to Cade Roux for this tip.

  • Why is MySQL with InnoDB doing a table scan when key exists and choosing to examine 70 times more ro

    - by andysk
    Hello, I'm troubleshooting a query performance problem. Here's an expected query plan from explain: mysql> explain select * from table1 where tdcol between '2010-04-13:00:00' and '2010-04-14 03:16'; +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | 1 | SIMPLE | table1 | range | tdcol | tdcol | 8 | NULL | 5437848 | Using where | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ 1 row in set (0.00 sec) That makes sense, since the index named tdcol (KEY tdcol (tdcol)) is used, and about 5M rows should be selected from this query. However, if I query for just one more minute of data, we get this query plan: mysql> explain select * from table1 where tdcol between '2010-04-13 00:00' and '2010-04-14 03:17'; +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | 1 | SIMPLE | table1 | ALL | tdcol | NULL | NULL | NULL | 381601300 | Using where | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ 1 row in set (0.00 sec) The optimizer believes that the scan will be better, but it's over 70x more rows to examine, so I have a hard time believing that the table scan is better. Also, the 'USE KEY tdcol' syntax does not change the query plan. Thanks in advance for any help, and I'm more than happy to provide more info/answer questions.

  • If I re-key a SSL certificate for a 2nd/backup server, does the original still work?

    - by Matt
    We have a production server with a wildcard SSL certificate. I'm in the process of creating a backup/failover server that will host the same domains, and therefore will also need the SSL certificate. The certificate on the primary server was installed with the private key non-exportable, so I am unable to export the certificate for installation on the failover server. My question then is - if I re-key the certificate from Go Daddy, does the original certificate installed on the primary server cease to be valid? As an aside, the original (primary) server is IIS 6, the failover is IIS 7 (once the failover is operational, we'll likely upgrade the primary).

  • (Vista) Discover what app is reserving a shortcut key?

    - by Eddie Parker
    My problem is this: I've always managed to map WIN+V to foobar2000's "Next song" keyboard shortcut. For some reason, on this new machine, I can't. I've done this before on Vista, so the only thing I can think of is that some other application is holding onto this shortcut key. When I try to assign the shortcut key in foobar2000, nothing registers. When I press it outside of foobar2000, nothing occurs either. I'm at a loss as to how to proceed. Are there any apps to see what hooks are being requested by what application? Or is there a better way of diagnosing this?

  • In what way does non-"full n-key rollover" hinder fast typists?

    - by Michael Kjörling
    Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

  • Mapping composite foreign keys in a many-many relationship, with overlapping components.

    - by Kirk Broadhurst
    I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

  • Foreign key not working in MySQL: Why can I INSERT a value that's not in the foreign column?

    - by stalepretzel
    I've created a table in MySQL: CREATE TABLE actions ( A_id int NOT NULL AUTO_INCREMENT, type ENUM('rate','report','submit','edit','delete') NOT NULL, Q_id int NOT NULL, U_id int NOT NULL, date DATE NOT NULL, time TIME NOT NULL, rate tinyint(1), PRIMARY KEY (A_id), CONSTRAINT fk_Question FOREIGN KEY (Q_id) REFERENCES questions(P_id), CONSTRAINT fk_User FOREIGN KEY (U_id) REFERENCES users(P_id)); This created the table I wanted just fine (although a "DESCRIBE actions;" command showed me that the foreign keys were keys of type MUL, and I'm not sure what this means). However, when I try to enter a Q_id or a U_id that does not exist in the questions or users tables, MySQL still allows these values. What did I do wrong? How can I prevent a table with a foreign key from accepting invalid data? If I add TYPE=InnoDB to the end, I get an error: ERROR 1005 (HY000): Can't create table './quotes/actions.frm' (errno: 150) Why might that happen? I'm told that it's important to enforce data integrity with functional foreign keys, but also that InnoDB should not be used with MySQL. What do you recommend?

  • Tutorial for texture mapping a map onto an Open GL ES sphere?

    - by hotpaw2
    I'm not looking for a library or even open source code. I want to learn how to do this on my own. Where do I start to find an online tutorial, a book chapter, or other educational material for generating a polygonal model of a 3D sphere suitable for feeding to Open GL ES on an iPhone, and then mapping the polygons to some sort of 2D map data so I can texture map the sphere? Is there some sort of software tool (blenders? mayan?) with a tutorial on how to do generate this data? Where is the best place to start?

  • Creating an application that can open files of a given format

    - by Brian Postow
    I've got an app, written in Obj-C. The info.plist has a list of file types that the app can open. I'm pretty sure that this is working because when I try to drag a file of an unacceptable type, the app doesn't highlight, but when I drag a file of an acceptable type, it does highlight, and lets me drop. When I drop, the app starts up, correctly, however, then I get a dialog saying: The document "foo.tiff" could not be opened. DocView cannot open files in the "TIFF File" format. I DO have this in my info.plist <key>CFBundleTypeExtensions</key> <array> <string>tif</string> <string>tiff</string> </array> <key>CFBundleTypeIconFile</key> <string>TIFFFile.icns</string> <key>CFBundleTypeName</key> <string>TIFF File</string> <key>CFBundleTypeOSTypes</key> <array> <string>TIFF</string> </array> <key>CFBundleTypeRole</key> <string>Viewer</string> <key>LSHandlerRank</key> <string>Documents/</string> Thanks.

  • How can I stop Chromium from putting focus in the address bar when using the up arrow key to scroll

    - by codeLes
    This is bugging me. I'm at a web page, any web page, and I am scrolling back to the top of the page with the up arrow key as I tend to do when browsing a page and once I get to the top of the page if I don't pay attention and hit the key one more times than is needed Chromium in all it's wisdom decides I must want to do something with the address so it places the focus in the address bar. ARGH! Any way to stop this? I'm running Ubuntu 9.04 Jaunty and have installed the nightly build version of Chromium PPA.

  • How to swap ctrl and fn key on a MacBook Pro running Windows 7 via Boot Camp?

    - by hobbes3
    There are sooooo many discussion on the internet about swapping the fn and ctrl key on a MacBook Pro. On the Mac side, a new software called ReMap4MacBook does a perfect job swapping the two key. But on the PC side (specifically Windows 7), I can't really find a definitive answer. Most post refer to this article but I read the loooong article and followed the instructions to no avail. I remember there used to be a program (maybe it was on XP) that not only swapped the two keys but it also controlled the fans on the MacBook Pro. But I can't remember the name and I also recall that that program stopped being updated like years ago. EDIT: It's called Input Remapper. So I am hoping there exist a simple program that I can simply run to swap those two keys.

  • How can I run Ghost from a bootable USB key drive?

    - by Joe Philllips
    I have a laptop that does not have a cd-rom or floppy drive. It is able to boot from USB though. I have a disk image (ghost) of the disk that I need to restore back onto the laptop. I can't find a way to actually run the Ghost utility from a USB key though. I believe the ghost.exe should run from within DOS just fine but I can't seem to create a bootable USB key with DOS on it that allows me to run an EXE. Edit: I managed to find a Ghost utility that I could load from a bootable USB drive. Unfortunately, when I plug in my NTFS external drive (USB), it is not detected.

  • cygWin connect by SSH using RSA key; ssh.exe couldn't create /home/user/.ssh

    - by Kirzilla
    I'm using Win XP and I'm trying to connect by SSH to remote host using RSA key. I've investigated that cygWin recognizes Documents and Settings dir as home directory Z:\app\cwRsync\bin>cygpath -H /cygdrive/c/Documents and Settings I've created .ssh directory in Documents and Settings/user/.ssh and moved known_hosts, id_rsa, id_rsa.pub there. Now, I'm trying to connect via ssh.exe to remote host Z:\app\cwRsync\bin>ssh -p 22 [email protected] Could not create directory '/home/user/.ssh'. The authenticity of host '[remotehost.com]:22 ([remotehost.com]:22)' can't be established. RSA key fingerprint is f7:f4:2c:e0:c6:7e:d2:a4:45:70:63:df:bf:f2:84:46. Are you sure you want to continue connecting (yes/no)? What I'm doing wrong? Why ssh.exe couldn't create directory /home/user/.ssh? Thank you.

  • Outlook Registry Key Damaged; Tried "Fix It" and lost everything

    - by Ray
    My outlook 2007 (on Windows 7 64 bit) worked fine for two weeks. I then installed a printer/scanner/copier and the Outlook Window wouldn't open. I went to Microsoft's website and found a page that said my registry key was damaged. The page had a link to a Fix It program. I ran the program and it looks like all my Outlook data was wiped out. Can I get the data back? For future reference, how should I protect myself if the key goes bad again? Do you think I should unistall Outlook and re-install?

  • Is it secure to store the cert/key on a private AMI?

    - by Phillip Oldham
    Are there any major security implications to bundling a private AMI which contains the private key/certificate & environment variables? For resiliency I'm creating an EC2 image which should be able to boot and configure itself without any intervention. After boot it will attempt to: Attach & mount specific EBS volume(s) Associate a specific Elastic IP Start issuing backups of the EBS volume(s) to S3 However, to do this it will need the private key/pem files and will need certain environment variables to be available on start-up. Since this is a private AMI I'm wondering if it will be "safe" to store these variables/files directly in the image so that I don't need to specify any user-data information and can therefore start a new instance remotely (from my iPhone, if needed) should the instance be terminated for any reason.

  • How to specify an SSH key for Hudson with git plugin?

    - by jlpp
    I've got Hudson (continuous integration system) with the git plugin running on a Tomcat Windows Service. msysgit is installed and the msysgit bin dir is in the path. PuTTY/Pageant/plink are installed and msysgit is configured to use them. The trouble I'm running in to, I think, is that the user who owns the Tomcat/Hudson service (Local System) has no SSH key set up to be able to clone the git repository. When the git Hudson plugin tries to clone it gives the error: $ git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" ERROR: Error cloning remote repo 'origin' : Could not clone git@hostname:project.git ERROR: Cause: Error performing git clone -o origin git@hostname:project.git e:\HUDSON_HOME\jobs\Project Trunk\workspace Trying next repository ERROR: Could not clone from a repository FATAL: Could not clone hudson.plugins.git.GitException: Could not clone My question is, how can I set things up so that the git plugin/msysgit know to use a particular SSH private key when trying to clone? I don't think Pageant will work because the Tomcat service is running as the "Local System" user, but I may be wrong.

  • How can I toggle Full Screen mode in Remote Desktop without a Break key?

    - by Jay Bazuzi
    My small laptop has a small keyboard, which lacks a Pause/Break key. Ctrl-Alt-Break toggles Full Screen mode in Windows Remote Desktop. Without a Break key, how can I enter Full Screen mode? I know I can exit fullscreen mode with the mouse. Maximizing the window doesn't help. This matters more on small laptops because the screens are small (so you need all the real estate you can get) and because the keyboard lacks dedicated PgUp/PgDn and other dedicated keys (so I can't easily use the RDP alternatives like Alt-PgUp).

  • How do I restart mysql and where is my.cnf file

    - by dorelal
    I am using snow leopard mac. I installed mysql on my machine using instructions mentioned here. Everything works great. However I have two questions. 1) Where is my.cnf file? I searched the whole file system and result is empty. Is it possible that there is no my.cnf and mysql works with default values. If yes then probably I should create my.inf at /etc/mysql. Is that right? 2) How do I restar server. I know it gets started when I restart my machine. Here is what plist looks like. mysqld_safe does not let me restart server. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <true/> <key>Label</key> <string>com.mysql.mysqld</string> <key>Program</key> <string>/usr/local/mysql/bin/mysqld_safe</string> <key>RunAtLoad</key> <true/> <key>UserName</key> <string>mysql</string> <key>WorkingDirectory</key> <string>/usr/local/mysql</string> </dict> </plist>

  • Which is faster in memory, ints or chars? And file-mapping or chunk reading?

    - by Nick
    Okay, so I've written a (rather unoptimized) program before to encode images to JPEGs, however, now I am working with MPEG-2 transport streams and the H.264 encoded video within them. Before I dive into programming all of this, I am curious what the fastest way to deal with the actual file is. Currently I am file-mapping the .mts file into memory to work on it, although I am not sure if it would be faster to (for example) read 100 MB of the file into memory in chunks and deal with it that way. These files require a lot of bit-shifting and such to read flags, so I am wondering that when I reference some of the memory if it is faster to read 4 bytes at once as an integer or 1 byte as a character. I thought I read somewhere that x86 processors are optimized to a 4-byte granularity, but I'm not sure if this is true... Thanks!
