• Info on UIDeviceFamily key in Info.plist

  - by dbv

  The iPad programming guide says I have to include the UIDeviceFamily key in Info.plist. It also says that the transitioning a target to iPad should have added the key. It didn't. I tried creating blank projects, both iPad-only and universal, and neither got that key. Google comes up short too. What's the story on this mysterious key? The simulator doesn't mind the fact it's missing.

• How does one actually use the UIRequiredDeviceCapabilities key?

  - by Andy

  I followed exactly what I thought I understood the steps to be in the iPhone Programming Guide for specifying that my app requires telephony (I opened MyApp-info.plist, added a new key called UIRequiredDeviceCapabilties, set the key type to Dictionary, added a new row with key set to "telephony", type Boolean, value YES), and sent my app off to Apple. Lo and behold, eleven days later, I get a message from Apple that it's been rejected for not using the UIRequiredDeviceCapabilities key. WTF? How are you actually supposed to implement this?

• Deterministic key serialization

  - by Mike Boers

  I'm writing a mapping class which uses SQLite as the storage backend. I am currently allowing only basestring keys but it would be nice if I could use a couple more types hopefully up to anything that is hashable (ie. same requirements as the builtin dict). To that end I would like to derive a deterministic serialization scheme. Ideally, I would like to know if any implementation/protocol combination of pickle is deterministic for hashable objects (e.g. can only use cPickle with protocol 0). I noticed that pickle and cPickle do not match: >>> import pickle >>> import cPickle >>> def dumps(x): ... print repr(pickle.dumps(x)) ... print repr(cPickle.dumps(x)) ... >>> dumps(1) 'I1\n.' 'I1\n.' >>> dumps('hello') "S'hello'\np0\n." "S'hello'\np1\n." >>> dumps((1, 2, 'hello')) "(I1\nI2\nS'hello'\np0\ntp1\n." "(I1\nI2\nS'hello'\np1\ntp2\n." Another option is to use repr to dump and ast.literal_eval to load. This would only be valid for builtin hashable types. I have written a function to determine if a given key would survive this process (it is rather conservative on the types it allows): def is_reprable_key(key): return type(key) in (int, str, unicode) or (type(key) == tuple and all( is_reprable_key(x) for x in key)) The question for this method is if repr itself is deterministic for the types that I have allowed here. I believe this would not survive the 2/3 version barrier due to the change in str/unicode literals. This also would not work for integers where 2**32 - 1 < x < 2**64 jumping between 32 and 64 bit platforms. Are there any other conditions (ie. do strings serialize differently under different conditions)? (If this all fails miserably then I can store the hash of the key along with the pickle of both the key and value, then iterate across rows that have a matching hash looking for one that unpickles to the expected key, but that really does complicate a few other things and I would rather not do it.) Any insights?

• Defining a different primary key in Mongomapper

  - by ming yeow

  I am defining a primary key in MongoMapper. class B key :_id, string key :externalId, string end The problem is that everything i add a new record in B, it appears that I need to explicity specify the _id, when it is already defined in the external id B.new(:_id=>"123", :external_id=>"123 ) That does not quite make sense. There should be a way to specify externalId as the primary key, no?

• How to implement context menu on key press instead of long click/tap

  - by takyon

  I have a ListActivity and I want to implement context menu for each of the list elements. I know that the common way to do this is to show the context menu on long click/tap. I want to know if there is a way to show the context menu for each element on a key press(preferably the menu key). To rephrase my question, how can I trigger the context menu and not the options menu by pressing the menu key(or any other key).

• Can I change an NSDictionaries key?

  - by Mark Reid

  I have an NSDictionary object that is populated by NSMutableStrings for its keys and objects. I have been able to change the key by changing the original NSMutableString with the setString: method. They key however remains the same regardless of the contents of the string used to set the key initially. My question is, is the key protected from being changed meaning it will always be the same unless I remove it and add another to the dictionary? Thanks.

• Disable Windows Key Hotkeys when using Virtualbox

  - by statenjason

  I'm currently running a VirtualBox of Arch Linux with Windows 7 x64 as the host. In Arch, I use dwm for window management. As dwm is heavily dependent on hotkeys, I've used the ALT key as its META key to prevent conflict with the Windows 7 host. However, when using emacs (also heavy hotkey usage) within dwm, there are issues because it's also using ALT for its own META. I'd like to change either dwm or emacs to use the windows key as META, but commands such as Win+L will be captured by the host machine and lock my system. Is there any way to prevent these hotkeys from being triggered while within VirtualBox?

• What key works like End using a Mac with Synergy

  - by Toby Allen

  I have recently got a Mac mini to do IPhone Dev on (like many others) and I am using the excellent Synergy to share one keyboard and mouse with 2 machines and 2 monitors. Everything is lovely and it works a treat. I got used to using the mac, and the alt key works like command button on the mac however one thing I cant figure out is the End key. I use this a lot on windows when wanting to jump to the end of a line of text, however if I press it over synergy on my mac it jumps to the end of the page. Anyone know the key combination I need to get what I want?

• Postfix "warning: cannot get RSA private key from file"

  - by phew

  I just followed this tutorial to set up a postfix mailserver with dovecot and mysql as backend for virtual users. Now I got the most parts working, I can connect to pop3 pop3s imap and imaps. Using echo TEST-MAIL | mail [email protected] works fine, when I log into my hotmail account it shows the email. It also works in reverse hence my MX entry for mydomain.com finally has been propagated, so I am being able to receive emails sent from [email protected] to [email protected] and view them in Thunderbird using STARTTLS via IMAP. Doing a bit more research after I got the error message "5.7.1 : Relay access denied" when trying to send mails to [email protected] using Thunderbird being logged into [email protected], I figured out that my server was acting as an "Open Mail Relay", which - ofcourse - is a bad thing. Digging more into the optional parts of the tutorial like shown workaround.org/comment/2536 and workaround.org/ispmail/squeeze/postfix-smtp-auth I decided to complete these steps aswell to be able to send mails via [email protected] through Mozilla Thunderbird, not getting the error message "5.7.1 : Relay access denied" anymore (as common mailservers reject open relayed emails). But now I ran into an error trying to get postfix working with SMTPS, in /var/log/mail.log it reads Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: cannot get RSA private key from file /etc/ssl/certs/postfix.pem: disabling TLS support Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:650:Expecting: ANY PRIVATE KEY: Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib:ssl_rsa.c:669: That error is logged right after I try to send a mail from my newly installed mailserver using SMTP SSL/TLS via port 465 in Thunderbird. Thunderbird then tells me a timeout occured. Google has a few results concerning that problem, yet I couldn't get it working with any of those. I would link some of them here but as a new user I am only allowed to use two hyperlinks. My /etc/postfix/master.cf looks like smtp inet n - - - - smtpd smtps inet n - - - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes and nmap tells me PORT STATE SERVICE [...] 465/tcp open smtps [...] my /etc/postfix/main.cf looks like smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no append_dot_mydomain = no readme_directory = no #smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem #default postfix generated #smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key #default postfix generated smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem smptd_tls_key_file = /etc/ssl/private/postfix.pem smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smptd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination myhostname = mydomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 mailbox_command = /usr/lib/dovecot/deliver The *.pem files were created like described in the tutorial above, using Postfix To create a certificate to be used by Postfix use: openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/postfix.pem -keyout /etc/ssl/private/postfix.pem Do not forget to set the permissions on the private key so that no unauthorized people can read it: chmod o= /etc/ssl/private/postfix.pem You will have to tell Postfix where to find your certificate and private key because by default it will look for a dummy certificate file called "ssl-cert-snakeoil": postconf -e smtpd_tls_cert_file=/etc/ssl/certs/postfix.pem postconf -e smtpd_tls_key_file=/etc/ssl/private/postfix.pem I think I don't have to include /etc/dovecot/dovecot.conf here, as login via imaps and pop3s works fine according to the logs. Only problem is making postfix properly use the self-generated, self-signed certificates. Any help appreciated! EDIT: I just tried this different tutorial on generating a self-signed certificate for postfix, still getting the same error. I really don't know what else to test. I also did check for the SSL libraries, but all seems to be fine: root@domain:~# ldd /usr/sbin/postfix linux-vdso.so.1 => (0x00007fff91b25000) libpostfix-global.so.1 => /usr/lib/libpostfix-global.so.1 (0x00007f6f8313d000) libpostfix-util.so.1 => /usr/lib/libpostfix-util.so.1 (0x00007f6f82f07000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f6f82cb1000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00007f6f82910000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x00007f6f826f7000) libdb-4.8.so => /usr/lib/libdb-4.8.so (0x00007f6f8237c000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f6f82164000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f6f81f4e000) libc.so.6 => /lib/libc.so.6 (0x00007f6f81beb000) libdl.so.2 => /lib/libdl.so.2 (0x00007f6f819e7000) libz.so.1 => /usr/lib/libz.so.1 (0x00007f6f817d0000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f6f815b3000) /lib64/ld-linux-x86-64.so.2 (0x00007f6f83581000) After following Ansgar Wiechers instructions its finally working. postconf -n contained the lines as it should. The certificate/key check via openssl did show that both files are valid. So it indeed has been a permissions problem! Didn't know that chown'ing the /etc/ssl/*/postfix.pem files to postfix:postfix is not enough for postfix to read the files.
