Now available for download release 2.5 of WP! Account upgrade of this site within a few days, just long enough to test the upgrade. The official announcement, which carry the first few lines, is located here .

WordPress 2.5, the culmination of six months of work by the WordPress community, people just like you. The improvements in 2.5 are Numerous, and Almost Entirely a result of your feedback: multi-file uploading, one-click plugin upgrades, built-in galleries, customizable dashboard, salted passwords and cookie encryption, media library, a WYSIWYG That Does not mess with your code, concurrent post editing protection, full-screen writing, and search That covers posts and pages.

UPDATE: I just upgraded to WordPress. I must say, the community has done an excellent job, especially as regards the management of the plugin is now really idiot-proof.

Conditional comments are no special instructions interpretable by the browser Internet Explorer from Microsoft Windows. They are already supported by version 5.0, but very few are able to exploit its considerable potential, especially in the correction of abnormal interpretations of CSS right from the browser from Microsoft.

You can use conditional comments distinguishing even the version of Internet Explorer used by the navigator, achieving effects (or corrections) differ depending on the characteristics (or lack) of specific version.

Conditional comments follow a very simple syntax, as in the following:

<!--[if IE 6]>
Qui ci metto istruzioni specifiche per Internet Explorer 6
<![endif]-->

As seen, the conditional comment is a command enclosed in HTML comment markers: in this way the browser does not support this feature completely ignore the comment and the instructions contained therein.

Attention! For this reason, conditional comments can not be used directly in the style sheets, but must be included must be in normal HTML pages.

Here's another simple but comprehensive example:

<p><!--[if IE]>
Stai utilizzando Internet Explorer<br />
<![endif]-->
<!--[if IE 5]>
Stai utilizzando Internet Explorer 5<br />
<![endif]-->
<!--[if IE 5.0]>
Stai utilizzando Internet Explorer 5.0<br />
<![endif]-->
<!--[if IE 5.5]>
Stai utilizzando Internet Explorer 5.5<br />
<![endif]-->
<!--[if IE 6]>
Stai utilizzando Internet Explorer 6<br />
<![endif]-->
<!--[if IE 7]>
Stai utilizzando Internet Explorer 7<br />
<![endif]-->
<!--[if gte IE 5]>
Stai utilizzando Internet Explorer, versione 5 o superiore<br />
<![endif]-->
<!--[if lt IE 6]>

<![endif]-->
<!--[if lte IE 5.5]>
Stai utilizzando Internet Explorer, versione inferiore o uguale alla 5.5<br />
<![endif]-->

I quote here in full the page that contains the examples published on the official website of the project rdiff-backup. I do not exclude the ability to provide its gradual translation, in the coming days, weather permitting.

rdiff-backup examples

Sections

• Backing up
• Restoring
• Deleting files older
• File selection with include / exclude options
• Getting information about the backup directory
• Miscellaneous other commands

Backing up

• Simplest case-backup local directory foo to local directory bar. bars will end up copy of foo, except it will Contain the directory foo / rdiff-backup-data, 'which will allow rdiff-backup to restore previous states.
  rdiff-backup foo bar
• Simple houses remote-backup directory / some / local-dir to the directory / whatever / remote-dir on the machine hostname.net. It uses ssh Necessary to open the pipe to the remote copy of rdiff-backup. Just like the above except one directory is on a remote computer.
  rdiff-backup /some/local-dir hostname.net::/whatever/remote-dir
• This time the source directory is remote and the destination is local. Also, we have specified the username on the remote host (by default ssh will attempt to log you in with the username you have examination on the local host).
  rdiff-backup user@hostname.net::/remote-dir local-dir
• It is even possible for Both the source and destination directories to be on other machines. Also below we have added the-v5 switch for Greater verbosity (verbosity settings go from 0 to 9, with 3 as the default), and the-print-statistics switch so some statistics will not be displayed at the end (even without this switch, the statistics will still be saved in the rdiff-backup-data directory).
  rdiff-backup -v5 --print-statistics user1@host1::/source-dir user2@host2::/dest-dir

Restoring

• Suppose we have discussed earlier run rdiff-backup foo bar, With Both foo and bar local. We accidentally deleted foo / dir and now want to restore it from bar / dir.
  cp -a bar/dir foo/dir That's right, since rdiff-backup makes a mirror, we can retrieve files using standard commands like cp.
• For the rest of the examples in the section, we will assume That the user has backed up with the command rdiff-backup local-dir host.net :: / remote-dir. Of course, in All These examples it would be 'equally possible to have the source being remote and the backup directory local.In this case we can not use cp to copying host.net :: remote-dir/file to local-dir / Files Because They Are on different machines. We can get rdiff-backup to restore the current version of that file using Either of These ::
  rdiff-backup --restore-as-of now host.net::/remote-dir/file local-dir/file
rdiff-backup -r now host.net::/remote-dir/file local-dir/file rdiff-backup --restore-as-of now host.net::/remote-dir/file local-dir/file
rdiff-backup -r now host.net::/remote-dir/file local-dir/file The-restore-as-of (or-r for short) switch tells rdiff-backup to restore instead of backup, and the Indicates the current time now option.
• But the main advantage of rdiff-backup is it That Keeps version history. This command restores host.net :: / remote-dir/file as it was 10 days ago into a new location / tmp / file.
  rdiff-backup -r 10D host.net::/remote-dir/file /tmp/file Other acceptable time strings include 5m4s (5 minutes and 4 seconds) and 03.05.2002 (March 5th, 2002). For more information, see the TIME FORMATS section of the manual page.
• Finally, we can use rdiff-backup to restore from an increment file directory. Increment files are stored in host.net :: / remote-dir/rdiff-backup-data/increments and hold the previous versions of changed files. If you Directly Specify one:
  rdiff-backup host.net::/remote-dir/rdiff-backup-data/increments/file.2003-03-05T12:21:41-07:00.diff.gz local-dir/file rdiff-backup will tell That from the filename it is an increment files rdiff-backup and restore Thus enter mode. Above the restored version is written to local-dir/file.

Deleting files older

Although rdiff-backup tries to save space by only storing files Differences, Eventually may run out space in the destination directory. rdiff-backup's-remove-older-than mode can be used to delete older increments.

This section assumes That rdiff-backup has-been used in the past to back up to host.net :: / remote-dir, but all commands would work locally too, if the hostname Were ommitted.

• Deletes all commands this information Concerning Which files have not Been current versions for 2 weeks:
  rdiff-backup --remove-older-than 2W host.net::/remote-dir Notes That Which Has not changed an existing file for a year will still be preserved. But a file was deleted 15 days ago Which can not be restored after this command is run.
• As When restoring, there are a variety of ways to Specify the time. The 20B below tells rdiff-backup to only preserve information from the last 20 rdiff-backup sessions. (NNB syntax is only available in versions after 0.13.1.)
  rdiff-backup --remove-older-than 20B host.net::/remote-dir

File selection with include / exclude options

Sometimes you do not want to back up all files. Various-The-include and exclude options can be used to select Exactly Which files to back up. See the man page for a list of all the options and Their definitions.

• In this example we exclude / mnt / backup to avoid an endless loop.
  rdiff-backup --exclude /mnt/backup / /mnt/backup (Actually rdiff-backup can automatically detect simple loops like the one above.) This is just an example, in reality it would be important to exclude / proc as well.
• This example is more realistic. We have Excluded / proc, / tmp, and / mnt. / Proc particolare Should never be backed up. Also, the source directory happens to be remote.
  rdiff-backup --exclude /tmp --exclude /mnt --exclude /proc user@host.net::/ /backup/host.net
• Multiple include and exclude options take precedence in the order They Are Given. The following command would back up / usr / local / bin but not / usr / bin.
  rdiff-backup --include /usr/local --exclude /usr / host.net::/backup
• rdiff-backup uses rsync-like wildcards, where ** matches any path and * matches any path without a / in it. Thus this command:
  rdiff-backup --include /usr/local --include /var --exclude '**' / /backup backs up only the / usr / local and / var directories. The single quotes "are not part of rdiff-backup and are only used Because many shells will expand **.
• Here is to more complicated example:
  rdiff-backup --include '**txt' --exclude /usr/local/games --include /usr/local --exclude /usr --exclude /backup --exclude /proc / /backup The above command will back up any files ending in txt, even / usr / local / games / tennis / scores.txt Because That includes Highest has precedence. The contents of the directory / usr / local / bin will get backed up, but not / usr / share or / usr / local / games / tennis.
• Also rdiff-backup can accept a list of files to be backed up. If the file include-list contains These two lines:
  /var
/usr/bin/gzip /var
/usr/bin/gzip Then this command:
  rdiff-backup --include-filelist include-list --exclude '**' / /backup
  would only back up the files / var, / usr, / usr / bin and / usr / bin / gzip, but not / var / log or / usr / bin / gunzip. That this differs from the known-include option, since-include / var Also would match / var / log.
• Both The Same file list can include and exclude files. If we create a file-list includes Called That These lines contains:
  **txt
- /usr/local/games
/usr/local
- /usr
- /backup
- /proc
  Then The following command will do Exactly The Same Thing as the complicated example two above.
  rdiff-backup --include-globbing-filelist include-list / /backup
  Above we have used-include-globbing-filelist instead of-include-filelist know That the lines would be Interpreted as if They Were specified on the command line. Otherwise, for instance, ** txt would be Considered the name of a file, not a globbing string.

Getting information about the backup directory

The following examples assume That you have run rdiff-backup-dir out-dir in the past.

• This command finds all files new or old frobniz Which Contain the string.
  find out-dir -name '*frobniz*'
  rdiff-backup Does not obscure the names of files at all, I Often using traditional tools work well.
• Either of These equivalent commands lists the times of the available versions of the files out-dir/file. It may be useful if you need to restore an older version of in-dir/file but not are sure which one.
  rdiff-backup --list-increments out-dir/file
rdiff-backup -l out-dir/file
• The following command lists all the files under out-dir/subdir Which has changed in the last 5 days.
  rdiff-backup --list-changed-since 5D out-dir/subdir
• This command lists all the files present in out-dir/subdir That Were 5 days ago. This includes files That have not changed recently as well as Those That Have Been deleted in the last 5 days.
  rdiff-backup --list-at-time 5D out-dir/subdir
• The first command below Compares the files in current dir-out (Which is on a remote computer) with the files in in-dir, displaying which ones have changed. The second command is similar to but Compares in-dir out-dir as it was 2 weeks in August
  rdiff-backup --compare in-dir user@host::out-dir
rdiff-backup --compare-at-time 2W in-dir user@host::out-dir
• rdiff-backup writes one statistics file per session out-dir/rdiff-backup-data to the directory. An average of the files can not be displayed using the-calculate-average option and Specifying the files to use statistics.
  rdiff-backup --calculate-average out-dir/rdiff-backup-data/session_statistics*

Miscellaneous other commands

• If you are HAVING problems connecting to a remote host, the-test-server command may be useful. This command simply verifies That there is a working rdiff-backup server on the remote side.
  rdiff-backup --test-server hostname.net::/ignored

Happy Easter!

This brief break from the common tasks for working at all - as well as of joy - of sincere reflection, especially for those who do not suffer: the profound significance of this memorial service - which is gradually becoming more and more a sort of pagan festival of regeneration - will face a different look at everything. The egg is very ancient times a symbol of life and positive. Symbol of new life, a metaphor for rebirth of body and nature. These meanings have been distributed in all continents and in more ancient traditions, so that to celebrate the arrival of warm weather (spring) they used to eat eggs. Read the rest »

Since a dozen portals of my clients have suffered serious consequences because of this phenomenon, reported here are some news here and there regarding the topic. If you think you fall into a similar situation, please contact me!

Attorneys for KinderStart.com, a portal dedicated to children's products, and Google reported a substantial damages claim: "Our main page has lost 70% of visits because of a decision by the arbitrary and opaque Google ".

KinderStart argues that California would lower the engine page-rank of the company's website, used by Google as a criterion for calculating the visibility of a web page. Although partial and certainly not very effective in describing the quality of a website, this "index" is advertised by Google in various ways, for example with its Toolbar. According to the lawyers of the U.S. site that produces a wrong suggestion on the actual popularity of the site itself.

Computer Point

Google does not care about anyone when it comes to borderline practices to gain popularity: in Mountain View are very serious about their PageRank, and any activities suspected of resorting to underhanded tricks soon starts to cause a downgrading of the site you are trying to promote: in the jargon we say that the site was hit by a Google Penalty. [...]

There are also many other situations that can lead to downgrading: a Google Bomb, material copied from another site, a page full of links strategic link.htm etc. The experts now prefer to talk about filters, since the techniques used by BigM have become increasingly sophisticated and are able to cover a wide range of possible tricks.

Interlinking from the same IP. For interlinking mean when webmasters link all their own sites even if they have irrelevant content, link to many sites with the same ip is considered by google something "bad" so this may be one reason for Many such sites have been downgraded.

The Damned Contest. I think that google does not clearly pleased that a site using this marketing strategy to get a ton of backlinks, it can be a striking esepio Gekissimo that contest with the nokia has got really a lot of popularity and backlinks, and perhaps was demoted for this. (As well as links to sell)

Sell ​​Links. Well this is known, everyone is against accandendo text links ads, but the problem riguara all networks of this kind, even Linklift service purchase and sale of links used by many Italians, to work around this problem would be enough that owners of the networks inserissero the nofollow attribute to links bought, but doing this more people would buy a link?

Trains and more. If we read the rules in the google webmaster guidelines capacity that a web page should not contain more than 100 links, unfortunately trains run from major sites, can easily exceed that number.

Today at 12:16:54 sign up for my domain name agliardi.it has finally ended.

Today I was presented a small problem: after adding a network printer HP Color LaserJet 2840 to a LAN I configured the client because stampassero that printer using the printing protocol CUPS . On all clients running Debian GNU / Linux iptables firewall protected. While the printer was located, was unable to start printing a document without first disabling the firewall.

Analysis and resolution of the problem have required only a few minutes! After having begun a `tail / var / log / messages I ran a test print:

#tail -f /var/log/messages
I got these videos immediately log lines generated by iptables:

Mar 18 12:34:53 localhost kernel: DROPPED IN= OUT=eth2 src=192.168.1.112 DST=192.168.1.138 LEN=78 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=1700 DPT=161 LEN=58
Mar 18 12:34:53 localhost Officejet_6300_series?ip=192.168.1.138: INFO: open device failed; will retry in 30 seconds...

In other words, exchanging packets on UDP port 161 was blocked (in nerdese: Dropped) from the firewall. It is enough to add a rule to the firewall to allow the transit of UDP packets on that port to resolve the problem.

The UNIX and Linux based systems retain information on the last modification and last access to each file. To view this information is used to command:

As for the syntax to be taken for the parameter orario_desiderato, `man` offers a simple explanation but quite exhaustive:

L'argomento è un numero decimale della forma [SS]AA]MMGGoomm[.ss] con l'ovvio significato. Se SS non è specificato, l'anno SSAA viene assunto nell'intervallo 1969-2068. Se ss non è specificato, viene assunto 0; può essere specificato nell'intervallo 0-61 in modo da potersi riferire a secondi saltati («leap second»). L'orario risultante viene interpretato come un orario nel fuso specificato dalla variabile ambientale TZ. Si ha un errore se l'orario ottenuto è precedente al 1 gennaio 1970
