• Challenge a .name registration?

  - by Shtééf

  The Wikipedia page on .name says the following: Registration restrictions: No prior restriction on registration, but registrations can be challenged if not by or on behalf of individual with name similar to that of domain, or fictional character in which registrant has rights But there's no further info on how this actually works. Can a .name domain registration be challenged, and if so, how?

• engine for responsive gameplay

  - by zaftcoAgeiha

  Many games have been praised for its responsive gameplay, where each user action input correspond to a quick and precise character movement (eg: super meat boy, shank...) What makes those games responsive? and what prevents other games from achieving the same? How much of it is due to the game framework used to queue mouse/keyboard events and render/update the game and how much is attributed to better coding?

• Scrambler in C#

  This program has two section of scrambling. First section, it transfers text into binary code. I was able to use bitArray, but I couldn't find a simple way to reverse it, so I added "character" and "binary" lists instead.

• Unconvert Text File from Binary Format

  - by Hammer Bro.

  I've got a rather large CSV file (~700MB) which I know to consist of lines of 27-character alpha-numeric hashes; no commas or anything fancy. Somehow, during its migration from Windows to Linux (via winSCP and then a few regular SCPs), it has converted into some kind of binary format I am unfamiliar with. If I open the file in vi, everything appears fine, and it says [converted] at the bottom, although I know it's not a line endings issue (and dos2unix doesn't help). If I 'head' the file, it looks proper except for a "ÿþ" at the beginning of the first line. If I open up the file in nano, however, I see the "ÿþ" at the start and then "^@" before every character (even newlines and EoF). If I try to re-save or copy the file (say via: head file.csv short.txt), this special encoding is preserved. I copied the first ten lines out of vi (which displays it properly) into my Windows clipboard via my SSH client, then pasted it into a new text file, test.txt. This file is visually identical when opened in vi (and similar through 'head', minus the "ÿþ"), although it's roughly half of the filesize. Additionally, file test.txt test.txt: ASCII text file short.txt short.txt: I have no idea what format this once-text file got converted to (it's notoriously hard to search the internet for symbols), but surely there must be some way to convert it back. Any ideas?

• Oracle 11gR2: NLS_CHARACTERSET accidentally removed with an UPDATE-Query

  - by Marco Nätlitz

  Hi folks, I have a fresh installation of Oracle 11gr2_x64 on CentOS. After the installation I wanted to get productive and started to import my dumps. One of the dumps caused characterset error so I tried to change the systems character-set to the one specified in the dump. I ran a statement like this: UPDATE nls_database_parameters SET parameter='WS....' WHERE parameter=’NLS_CHARACTERSET’; As you can see: I have written the value of the character-set in the parameter column instead of the value column. I guess I was just too much thinking about the problem instead of checking what I am typing there. After the query the parameter "NLS_CHARACTERSET" is gone and the server reports that the characterset is "(null)". I want to put the "NLS_CHARACTERSET" paramater back in the table but don't know how. If I try to do something like this INSERT INTO nls_database_parameters (PARAMETERS, VALUE) VALUES ("NLS_CHARACTERSET", "AL32UTF8"); I get the error: Fehler bei Befehlszeile:1 Spalte:84 Fehlerbericht: *Cause: SQL-Fehler: ORA-00984: Spalte hier nicht zulässig *Action: 00984. 00000 - "column not allowed here" Sorry that the error message is in German but it contains the Oracle error code. Do you have any idea how I can fix that? Thanks and best regards Marco

• mysql.proc has gone corrupt. How can I fix it?

  - by Metalcoder

  I have a server running Debian 5.0, and MySQL. Suddendly, MySQL stopped working, and after many attempts to fix it, I decided to reinstall it. I installed MySQL 5.1.63, and when started it goes to safe mode. I made some typing, and when I executed mysql_upgrade as root, it complained: ... Running 'mysql_fix_privilege_tables'...

• Munin node not listing any plugins on new Fedora 14 installation

  - by Dave Forgac

  I have just installed munin-node from the base repo on Fedora 14 and then started it. I found that my munin server is not able to collect data from this node so I tried connecting via telnet to test. When connecting via telnet I see that no plugins are listed: [dave@host ~]# telnet localhost 4949 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. # munin node at host.example.com list quit Connection closed by foreign host. [dave@host ~]# I did not modify anything after the installation. The munin-node.conf is allowing connections from 127.0.0.1 and the default set of plugins in /etc/munin/plugins/ are symlinked to the plugins in /usr/share/munin/plugins/. Here is the working output of the telnet test of the 'list' command should look like (this is on a Fedora 13 host): [dave@www ~]$ telnet localhost 4949 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. # munin node at www.example.com list apache_accesses apache_processes apache_volume cpu df df_inode entropy forks fw_packets if_err_eth0 if_err_eth1 if_eth0 if_eth1 interrupts iostat iostat_ios irqstats load memory munin_stats mysql_ mysql_bytes mysql_innodb mysql_queries mysql_slowqueries mysql_threads netstat open_files open_inodes postfix_mailqueue postfix_mailvolume proc_pri processes swap threads uptime users vmstat yum quit Connection closed by foreign host.

• compose-key mappings differ between gtk and qt apps

  - by intuited

  I'm noticing that there is an inconsistency in the output of one of the compose-key combos. When I type ( [Compose] . . ) under Chrome, gedit, gnome-terminal, or roxterm I get the character '?'. This is a small raised dot: $ echo -n '?' | xxd 0000000: cb99 .. When I type the same combo under konsole, yakuake, or kate, I get the character '…'. This is an ellipsis: $ echo -n '…' | xxd 0000000: e280 a6 ... This is not a font issue: if I copy-paste the characters from an app using one toolkit to an app using the other, its appearance is maintained. I use a few other combos pretty regularly and they seem to work consistently across toolkits. I think this is a pretty recent phenomenon. I upgraded from Ubuntu 8.10 to 9.10 fairly recently so this might be related. I'm not sure if this will reoccur if I restart X, and I'd rather not find out. Can someone explain how this is possible, and what I can do to resolve it? I'd like to have the ellipsis appear in all apps when that combo is entered.

• See former key sequences in vim

  - by Vasiliy Sharapov

  Sometimes I share screen shots and clips of vim usage with others. It would be nice to expand on the part of the status bar highlighted in this picture: I would like some way to make previous key sequences visible as well, such as: y2w jj f[ p 2d - You can see the key sequences leading up to the current one. I'll elaborate on my wish list at the bottom. Is something like this is available as a plugin or vim script? The sheer number of scripts available on vim online makes this hard to find by keyword. Some features I would hope for (but seem improbable): Delimit key sequences with a non-keyboard character instead of space, and a different one for the current command, so y2w jj f[ p 2d might become y2w¦jj¦f[¦p » 2d Replace keys that have a letter alternative with the alternative, such as the right arrow key - ^[[C with the equivalent l. Edit: To clarify, the right arrow key is a valid key in vim, but has no character to represent it, the l key preforms the same function and could/should substitute it. Have previous keystrokes run all the way to the beginning of the line (instead of just one or two), and just have vim's command prompt overwrite it when necessary. Replace some keystrokes with a more elegant alternative, for example hhhhh with 5h or more impressively d2f) with d% (in the appropriate situation).

• Export NFS path containing "-" (dash)

  - by qdot

  I'm in a bit of a pinch with NFS exports file. Specifically, I can't find a way to export a directory containing "-" in the path name. Manual (exports(5)) states: Also, each line may have one or more specifications for default options after the path name, in the form of a dash ("-") followed by an option list. The option list is used for all subsequent exports on that line only. It then states: If an export name contains spaces it should be quoted using double quotes. You can also specify spaces or other unusual character in the export name using a backslash followed by the character code as three octal digits. Unfortunately, that is not the case. Specifically, if the pathname contains "-", either verbatim, or with \055 or is enclosed in double quotes, it still refers to the name without "-" Any ideas? I have a large number of directories, all of the form /vol/buildsystem-s3c2440 /vol/buildsystem-tao3530 and I'd prefer to have them all available as nfs exports. Short of replacing the "-" with "_" everywhere in the scripts, can it be done with "-" ?

• Windows Vista claims wireless key is the wrong length

  - by humble coffee

  A family member of mine is house sitting and has been given the details of their wifi. The access point is an Airport Express, it has WEP encryption (I think) and they've been given a passphrase to use. I know it's a passphrase and not the encrypted key as it's an English word. The passphrase is 10 characters long. The problem is that Vista complains that it's not a valid key as it must be a 5 or 13 character non-hex key or a 10 or 26 character hex key. (From what I've read this suggests the encryption is WEP?) I've found a couple of suggested solutions, but I'm not actually at the house at the moment so I wanted to make sure I have a good chance of getting it to work when I'm there but have no internets to ask. Solution 1: Vista needs to be told explicitly what kind of encryption and key is being used. Specify in the connection settings that you are using WEP and that it is a "shared key". Solution2: Try converting the passphrase to hexadecimal using an ASCII-hex converter and entering that.

• Getting some French-Canadian keyboard strokes to work on English keyboard

  - by Gradient

  I'm trying to use some of the French-Canadian keyboard stokes I'm used to on an English keyboard. I would like to change the behaviour of some keys. I was able to implement these changes in Vim, but I would like them to be applied system-wide (for Windows and Ubuntu). Here's what I want to implement : If I press [a, the character printed is â. When I press [r, something that's supposed to stay normal, the characters printed are [r. If I hold [ for 3 seconds, [ is printed. I want this delay to be applied to all my modified keys. I want to map < to ' and the characters 'e to è. The complex problem here is that I only want the ' beside the ; key to produce the è character, NOT when I press the < (remapped to ') then e. I'll show you a .vimrc file that implements this, now I want this behavior system-wide: set timeout timeoutlen=3000 ttimeoutlen=100 inoremap [a â inoremap [A Â inoremap [e ê inoremap [E Ê inoremap [i î inoremap [I Î inoremap [o ô inoremap [O Ô inoremap [u û inoremap [U Û inoremap 'a à inoremap 'A À inoremap 'e è inoremap 'E È inoremap 'u ù inoremap 'U Ù inoremap }e ë inoremap }E Ë inoremap }i ï inoremap }I Ï inoremap }u ü inoremap }U Ü inoremap ]c ç inoremap ]C Ç inoremap / é inoremap < '

• Remove server hangs, gets stuck. How to debug?

  - by bibstha

  I have an vps running on VmWare ESX with Ubuntu 8.04 LTS. It has been running smoothly for the past 3 months, however recently we've notices two strange bugs. a. The server hangs, today was second time. The nature of the hang is very strange. I can ping to the server server, it sends back response fine. However all other services like sshd, apache, mysql etc do not respond at all. When working, telnet servername 22 Escape character is '^]'. SSH-2.0-OpenSSH_5.X Debian-5ubuntu1 And other web services would run fine. When its hung, I can make tcp connections to 22 as well as 80 but receive no response at all. telnet servername 22 Escape character is '^]'. How can I debug this problem? Is there any daemons I can run that will periodically log status? Please tell me as to how to proceed with it. b. The another strange problem is that, of lately I am unable to transfer files larger than around 100KB, smaller files of around 1-2 KB works file. scp anotherserver:filename . or wget http://www.example.com/file would get stuck. There is still around 6GB of space remaining, so I don't think that is an issue. Any pointers where I should look into?

• Certain Japanese characters aren't displayed properly

  - by Nisto

  On the following site: http://www.nciku.com/search/radical the first 2 characters on the second row of the "Step 2" table aren't displayed properly. All other characters look fine. I tried re-installing the Asian fonts via the checkboxes regarding Asian fonts in the "Regional and Language Options" control panel applet. I have tried removing every single Font from the Fonts folder (some were ofcourse not possible to remove), and re-installing them all again. I did this by... Running cmd Closing down the explorer process In cmd; using the command DEL /F /S /Q * in the Fonts folder Putting in my XP SP3 Retail disc In cmd; using expand -r *.tt_ in the I386 folder on the XP disc (and any other font file, in the I386\LANG folder) I also tried installing this pack from Microsoft, but this solved nothing either. I even tried running my browser (Firefox) through AppLocale. And changing character encoding -- again, does not help. I've also tried viewing the page in Internet Explorer. What could be wrong? I have checked my Fonts folder, to make sure that every single font available on the XP disc is available in WINDOWS\Fonts. What shows in the first square on the second row - I can't really tell what it's supposed to look like (but it's not the proper character)... but the second square shows a rectangular symbol containing HEX code. I've been in this situation before -- and it has been when I've been missing fonts. But how could I possibly be missing a necessary font? Shouldn't it be provided in the Asian "font packages"? I've talked to some other users that has viewed the page, and they had no problems displaying those characters on second row - even though they're only using the fonts provided on the Windows installation disc. Windows XP Professional Service Pack 3 (x86 - with latest updates) Firefox 3.6.15

• MySQL Config on Large Machine

  - by Jonathon

  We have a Windows 2003 Enterprise Edition server (64bit) running only MySQL 5.1.45 64-bit. It has 16G RAM and 10T of hard-drive space in RAID 10. We are having horrible performance from mysqld (85-100% CPU utilization). We were running a smaller machine with better performance, so I am assuming our my.ini file is not correct for our current machine. The my.ini file is as follows: [client] port=3306 [mysql] default-character-set=latin1 [mysqld] port=3306 basedir="D:/MySQL/" datadir="D:/MySQL/data" default-character-set=latin1 default-storage-engine=MYISAM sql-mode="" skip-innodb skip-locking max_allowed_packet = 1M max_connections=800 myisam_max_sort_file_size=5G myisam_sort_buffer_size=500M table_open_cache = 512 table_cache=8000 tmp_table_size=30M query_cache_size=50M thread_cache_size=128 key_buffer_size=3072M read_buffer_size=2M read_rnd_buffer_size=16M sort_buffer_size=2M #replication settings (this is the master) log-bin=log server-id = 1 Does anyone see anything wrong with this setup? For a machine with this much RAM, why in the world would mysqld eat up so much CPU? I know we can optimize some queries, etc., but it did run okay on a smaller machine, so I am pretty sure it is the config. Thanks in advance for any help.

• OS X: Storing MySQL data securely, on an encrypted FileVault image using a soft link

  - by GJ

  I am trying to get a macports-installed MySQL to use a data directory stored inside my FileVault-protected home dir. I used sudo cp -a /opt/local/var/db/mysql5 ~/db/ (the -a to ensure file permissions remain intact) and then replaced the original mysql5 directory with a soft link: sudo ln -s ~/db/mysql5 /opt/local/var/db/mysql5 However, when I now try to start MySQL it fails. It follows the soft link at least to the extent that it modifies some files in the ~/db/mysql5 dir, notably the error log which gets appended to it this: 110108 15:33:08 mysqld_safe Starting mysqld daemon with databases from /opt/local/var/db/mysql5 110108 15:33:08 [Warning] '--skip-locking' is deprecated and will be removed in a future release.

• Is there a POSIX pathname that can't name a file?

  - by Charles Stewart

  Are there any legal paths in POSIX that cannot be associated with a file, regular or irregular? That is, for which test -e "$LEGITIMATEPOSIXPATHNAME" cannot succeed? Clarification #1: pathnames By "legal paths in POSIX", I mean ones that POSIX says are allowed, not ones that POSIX doesn't explicitly forbid. I've looked this up, and the are POSIX specification calls them character strings that: Use only characters from the portable filename character set [a-zA-Z0-9._-] (cf. http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap03.html#tag_03_276); Do not begin with -; and Have length between 1 and NAME_MAX, a number unspecified for POSIX that is not less than 14. POSIX also allows that filesystems will probably be more relaxed than this, but it forbids the characters NUL and / from appearing in filenames. Note that such a paradigmatically UNIX filename as lost+found isn't FPF, according to this def. There's another constant PATH_MAX, whose use needs no further explanation. The ideal answer will use FPFs, but I'm interested in any example with filenames that POSIX doesn't expressly forbid. Clarification #2: impossibility Obviously, pathnames normally could be bound to a file. But UNIX semantics will tell you that there are special places that couldn't normally have arbitrary files created, like in the /dev directory. Are any such special places stipulated in POSIX? That is what the question is getting after.

• How to make emacs accept UTF-8 from the keyboard

  - by Brent.Longborough

  My friends have persuaded me to "try again" (about the 5th time in about 12 years) with emacs. I'm currently suffering a little, and need help with emacs + utf-8. I'm running the 23.3.1 emacs gui on Windows 7 with my own custom keyboard layout (built with MS Keyboard Layout Creator). The layout has a full ISO-8859-1 (Latin-1) character set, plus some additional characters from ISO-8859-9 (Latin-5, gis etc for Turkish) and w for Welsh (don't know where that one lives). In my .emacs, I have (blindly) added these lines: ;; key board / input method settings (setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-language-environment 'UTF-8) ; prefer utf-8 for language settings Now, when I enter characters from ISO Latin-1 from the keyboard, they are accepted without problems, but characters from outside Latin-1 are "translated" to an approximate character in Latin-1. Thus, for example, Latin-5 "g" gets converted to a plain "g". Cutting and pasting, however, work fine. Can anyone tell me what I'm doing wrong? I should like to make everything I do with emacs utf-8 with BOM.

• postfix - connection refused from behind NAT

  - by manchine

  When attempting to telnet postfix from a different host in the same LAN through the FQDN (and thus the LAN's public IP), the following error occurs: root@mailer:/var/log# telnet mail.domain.com 25 Trying 1.2.3.4... telnet: Unable to connect to remote host: Connection refused Other services can be reached from the exact same host, however: root@mailer:/var/log# telnet mail.domain.com 22 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u1 To make matters more intriguing, Postfix can be accessed from outside the LAN: nunos-mbp:mailog nzimas$ telnet mail.domain.com 25 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Postfix (Ubuntu) To sum thing up: a) Postfix (running on 10.10.10.4 / mail.domiain.com) refuses connection from a host in the same LAN (10.10.10.2), but only when queried through the FQDN (mail.domain.com) b) mail.domain.com accepts connections to other services (but Postfix) from 10.10.10.2 c) mail.domain.com accepts connections to all services, including Postfix, from the outside world If it were a firewall issue, then I believe it would not be possible to connect to any service from 10.10.10.2 through the FQSN / public IP. It ought to be some missing parameter in Postfix, although I haven't found any clear pointers so far.

• Custom Dreamweaver DocTypes

  - by Hugh Guiney

  Dreamweaver CS5 with Dreamweaver HTML5 Pack 1.2.7 Windows 7 x64 When I go to create a new document and select the HTML5 DocType, Dreamweaver gives me the legacy encoding/character set declaration: <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> I want to replace it with the new, abbreviated style: <meta charset="utf-8"> The relevant file seems to be %ProgramFiles(x86)%\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\NewDocuments\Default.html, which has a blank charset, that is then apparently replaced with the appropriate character set dynamically: <meta http-equiv="Content-Type" content="text/html; charset="> I changed it, but then new documents show up like this: <meta charset=""> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> It seems Dreamweaver added the legacy declaration back in after my modification—and as far as I can tell, there's no way to specify that the charset definition should go in-between the quotes, either. Additionally, any modifications to Default.html apply to every DocType, whereas I only want this change to apply to the HTML5 DocType. Is there anything in the configuration files that would allow me to make any of these customizations? If not, is there an extension that does it?

• how to rewrite '%25' in url

  - by nn4l

  My website software replaces space characters with '+' characters in the URL, A proper link would look like 'http://www.schirmacher.de/display/INFO/How+to+reattach+a+disk+to+XenServer' for example. Some websites link to that article but somehow their embedded editor can't handle the encoding, so what I see in the httpd log files is actually GET /display/INFO/How%2525252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer which of course leads to a 404 error. It seems that the '+' character is encoded as '%2b' and then the '%' character is encoded as '%25' - several times. Since there are many such references to different pages from different websites, I would like to rewrite the url so that the visitors get the correct page. Here's my attempt which does not work: RewriteRule ^(.*)%25(.*)$ $1%$2 [R=301] What it is supposed to do is: take everything before the %25 string and everything after it, concat those strings with a '%' in between, then redirect. With the example input URL the rule should rewrite to /display/INFO/How%25252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer followed by a redirect, then it should rewrite to /display/INFO/How%252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and again to /display/INFO/How%2bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and so on. Finally, after a lot of redirects I should have left /display/INFO/How%2bto%2breattach%2ba%2bdisk%2bto%2bXenServer which is a valid url equivalent to /display/INFO/How+to+reattach+a+disk+to+XenServer. My problem is that the expression does not match at all, so it does not even replace a single occurrence of %25. I understand that there is a limit in the number of redirects and I should really use the [N] flag however I don't even get the first step right.

• Weird rendering artefact in vim (terminal, not MacVim)

  - by Tobi Lehman

  Running Mac OS X, using either Terminal.app or iTerm2, there is a strange artefact with the character rendering that I have a hard time explaining and an even harder time understanding. I'll start with a video of my screen so that you can see and example of it in action: From the video you can see a few ways it is weird, for example, sometimes when I hit a letter in insert mode, the character is double printed. When I go into normal mode, the artefact remains. When I re-enter insert mode, hitting backspace copies the characters on the left to the position under the cursor. This has happened in OS X Lion, and Mountain Lion, under both Terminal.app and iTerm 2. This never happens under MacVim. Also, I use GNU/Linux on my other machine, and have never had this happen, I am pretty sure it is strictly a Mac OS X issue, but I do not know how to fix it. For a while, I've been working around it by using MacVim most of the time, but I prefer working in a terminal. Does anyone know what is happening here, and if so, how can I fix it? EDIT: I tried using the macvim Vim executable, and I still get strange artefacts, but they are localized to the left side of the screen, here is an example:
