Turning off Advanced Content Filtering in CKEditor

3rd February 2015

On one of my websites, I use Textpattern with CKEditor for editing of articles on there. This was working well until I upgraded CKEditor to a version with a number of 4.1 or newer because it started to change the HTML in my articles when I did not want it to do so, especially when it broke the appearance of the things. A search on Google revealed an unhelpful forum exchange that produced no solution to the issue so I decided to share one on here when I found it.

What I needed to do was switch off what is known as Advanced Content Filtering. It can be tuned but I felt that would take too much time so I implemented something like what you see below in the config.js with the ckeditor folder:

CKEDITOR.editorConfig = function( config ) {
config.allowedContent = true;
};

All settings go with the outer function wrapper and setting the config.allowedContent property to true within there sorted my problem as I wanted. Now, any HTML remains untouched and I am happy with the outcome. It might be better for features like Advanced Content Filtering to be switched off by default and turned on by those with the time and need for it, much like the one of the principles adopted by the WordPress project. Still, having any off switch is better than none at all.

Turning off the full height editor option in WordPress 4.0

10th September 2014

Though I keep a little eye on WordPress development, it is no way near as rigorous as when I submitted a patch that got me a mention on the contributor list of a main WordPress release. That may explain how the full editor setting, which is turned on by default passed by on me without my taking much in the way of notice of it.

WordPress has become so mature now that I almost do not expect major revisions like the overhauls received by the administration back-end in 2008. The second interface was got so right that it still is with us and there were concerns in my mind at the time as to how usable it would be. Sometimes, those initial suspicions can come to nothing.

However, WordPress 4.0 brought a major change to the editor and I unfortunately am not sure that it is successful. A full height editor sounds a good idea in principle but I found some rough edges to its present implementation that leave me wondering if any UX person got to reviewing it. The first reason is that scrolling becomes odd with the editor’s toolbar becoming fixed when you scroll down far enough on an editor screen. The sidebar scrolling then is out of sync with the editor box, which creates a very odd sensation. Having keyboard shortcuts like CTRL+HOME and CTRL+END not working as they should only convinced me that the new arrangement was not for me and I wanted to turn it off.

A search with Google turned up nothing of note so I took to the WordPress.org forum to see if I could get any joy. That revealed that I should have thought of looking in the screen options dropdown box for an option called “Expand the editor to match the window height” so I could clear that tickbox. Because of the appearance of a Visual Editor control on there, I looked on the user profile screen and found nothing so the logic of how things are set up is sub-optimal.  Maybe, the latter option needs to be a screen option now too. Thankfully, the window height editor option only needs setting once for both posts and pages so you are covered for all eventualities at once.

With a distraction-free editing option, I am not sure why someone went for the full height editor too. If WordPress wanted to stick with this, it does need more refinement so it behaves more conventionally. Personally, I would not build a website with that kind of ill-synchronised scrolling effect so it is something needs work as does the location of the Visual Editor setting. It could be that both settings need to be at the user level and not with one being above that level while another is at it. Until I got the actual solution, I was faced with using distraction-free mode all the time and also installed the WP Editor plugin too. That remains due to its code highlighting even if dropping into code view always triggers the need to create a new revision. Despite that, all is better in the end.

Setting the PHP version in .htaccess on Apache web servers

7th September 2014

The default PHP version on my outdoors, travel and photography website is 5.2.17 and that is getting on a bit now since it is no longer supported by the PHP project and has not been thus since 2011. One obvious impact was Piwik, which I used for web analytics and needs at least 5.3.2. WordPress 4.0 even needs 5.2.24 so that upgrade became implausible so I contacted Webfusion’s support team and they showed me how to get to at least 5.3.3 and even as far as 5.5.9. The trick is the addition of a line of code to the .htaccess file (near the top was my choice) like one of the following:

PHP 5.3.x

AddHandler application/x-httpd-php53 .php

PHP 5.5.x

AddHandler application/x-httpd-php55 .php

When I got one of these in place, things started to look promising but for a locked database due to my not watching how big it had got. Replacing it with two additional databases addressed the problem of losing write access though there was a little upheaval caused by this. Using PHP 5.5.9 meant that I spotted messages regarding the deprecation of the mysql_connect function so that needed fixing too (prefixing it with @ might be a temporary fix but a more permanent one always is better so that is what I did in the form of piggybacking off what WordPress uses; MySQLi and PDO_MySQL are other options). Sorting the database issue meant that I saw the upgrade message for WordPress as well as a mix of plugins and themes so all looked better and I need worry less about losing security updates. Also, I am up to the latest version of Piwik too and that’s an even better way to be.

Surveying changes coming in GNOME 3.10

20th October 2013

GNOME 3.10 came out last month but it took until its inclusion into the Arch and Antergos repositories for me to see it in the flesh. Apart from the risk of instability, this is the sort of thing at which rolling distributions excel. They can give you a chance to see the latest software before it is included anywhere else. For the GNOME desktop environment, it might have meant awaiting the next release of Fedora in order to glimpse what is coming. This is not always a bad thing because Ubuntu GNOME seems to be sticking with using a release behind the latest version. With many GNOME Shell extension writers not updating their extensions until Fedora has caught up with the latest release of GNOME for a stable release, this is no bad thing and it means that a version of the desktop environment has been well bedded in by the time it reaches the world of Ubuntu too. Debian takes this even further by using a stable version from a few years ago and there is an argument in favour of that from a solidity perspective.

Being in the habit of kitting out GNOME Shell with extensions, I have a special interest in seeing which ones still work or could work with a little tweaking and those which have fallen from favour. In the top panel, the major change has been to replace the sound and user menus with a single aggregate menu. The user menu in particular has been in receipt of the attentions of extension writers and their efforts either need re-work or dropping after the latest development. The GNOME project seems to have picked up an annoying habit from WordPress in that the GNOME Shell API keeps changing and breaking extensions (plugins in the case of WordPress). There is one habit from the WordPress that needs copying though and that is with documentation, especially of that API for it is hardly anywhere to be found.

GNOME Shell theme developers don’t escape and a large border appeared around the panel when I used Elementary Luna 3.4 so I turned to XGnome Enhanced (found via GNOME-Look.org) instead. The former no longer is being maintained since the developer no longer uses GNOME Shell and has not got the same itch to scratch; maybe someone else could take it over because it worked well enough until 3.8? So far, the new theme works for me so that will be an option should there a move to GNOME 3.10 on one of my PC’s at some point in the future.

Returning to the subject of extensions, I had a go at seeing how the included Applications Menu extension works now since it wasn’t the most stable of items before. That has improved and it looks very usable too so I am not awaiting the updating of the Frippery equivalent. That the GNOME Shell backstage view has not moved on that much from how it was in 3.8 could be seen as a disappointed but the workaround will do just fine. Aside from the Frippery Applications Menu, there are other extensions that I use heavily that have yet to be updated for GNOME Shell 3.10. After a spot of success ahead of a possible upgrade to Ubuntu GNOME 13.10 and GNOME Shell 3.8 (though I remain with version 13.04 for now), I decided to see I could port a number of these to the latest version of the user interface. Below, you’ll find the results of my labours so feel free to make use of these updated items if you need them before they are update on the GNOME Shell Extensions website:

Frippery Bottom Panel

Frippery Move Clock

Remove App Menu

Show Desktop

There have been more changes coming in GNOME 3.10 than GNOME Shell, which essentially is a JavaScript construction. The consolidation of application title bars in GNOME applications continues but a big exit button has appeared in the affected applications that wasn’t there before. Also there remains the possibility of applying the previously shared modifications to Nautilus (also known as Files) and a number of these usefully extend themselves to other applications such as Gedit too. Speaking of Gedit, this gains a very useful x of y numbering for the string searching functionality with x being the actual number of the occurrence of a certain piece of text in a file and y being its total number of occurrences.GNOME Tweak Tool has got an overhaul too and lost the setting that makes a folder path box appear in Nautilus instead of a location part, opening Dconf-Editor and going to org > gnome > nautilus > preferences and completing the tick box for always-use-location-entry will do the needful.

Essentially, the GNOME project is continuing along the path on which it set a few years ago. Though I would rather that GNOME Shell would be more mature, invasive changes are coming still and it leaves me wondering if or when this might stop. Maybe that was the consequence of mounting a controversial experiment when users were happy with what was there in GNOME 2. The arrival of Fedora 20 should bring with it an increase in the number of GNOME shell extensions that have been updated. So long as it remains stable Antergos is good have a look at the latest version of GNOME for now and Cinnamon fans may be pleased the Cinnamon 2.0 is another desktop option for the Arch-based distribution. An opportunity to say more about that may arrive yet once the Antergos installer stops failing at a troublesome package download; a separate VM is being set aside for a look at Cinnamon because it destabilised GNOME during a previous look.

A look at Ubuntu GNOME 13.10

12th October 2013

With its final release being near at hand, I decided to have a look at the beta release of Ubuntu GNOME 13.10 to get a sense of what might be coming. A misstep along the way had me inadvertently download and install the 64-bit edition of 13.04 into a VirtualBox virtual machine. The intention to update that to its soon to be released successor was scuppered by instability so I never did get to try out an in situ upgrade to 13.10. What I had in mind was to issue the following command:

gksu update-manager -d

However, I found another one when considering how Ubuntu Server might be upgraded without the GUI application that is the Update Manager. To update to a development version, the following command is what you need:

sudo do-release-upgrade -d

To upgrade to a final release of of a new version of Ubuntu, drop the -d switch from the above to use the following:

sudo do-release-upgrade

There is one further option that isn’t recommended for moving between Ubuntu versions but I use it to get updates such as new kernel subversions that are released:

sudo apt-get dist-upgrade

Rather than trying out the above, I downloaded the latest ISO image for the beta release of Ubuntu GNOME 13.10 and installed onto a VM that instead. Though it is the 32 bit version of the distro that is installed on my main home PC, it has been the 64 bit version that I have been trying. So far, that seems to be behaving itself even if it feels a little sluggish but that could be down to the four year old PC that hosts the virtual machine. For a while, I have been playing with the possibility of an upgrade involving an Intel Core i5 4670K CPU and 16 GB of RAM (useful for running multiple virtual machines at a time) along with any motherboard that supports those so looking at a 64 bit operating system has its uses.

The Linux kernel may be 3.11 but that is not my biggest concern. Neither is the fact that LibreOffice 4.1.2.3 was included and GIMP wasn’t, especially when that could be added easily anyway and it is version 2.8.6 that you get. The move to GNOME Shell 3.8 was what drew me to seeing what was coming because I have been depending on a number extensions. As with WordPress and plugins, GNOME Shell seems to have a tempestuous relationship with some of its extensions and I wanted to see which ones still worked. There also has been a change to the backstage application view in that you either get all installed applications displayed when you browse them or you have to start typing the name of the one you want to select it. Losing the categorical view that has been there until GNOME Shell 3.6 is a step backwards and I hope that version 3.10 has seen some sort of a reinstatement. There is a way to add these categories and the result is not as it once was either; also, it shouldn’t be necessary for anyone to dive into a systems innards to address things like this. With all the constant change, it is little wonder that Cinnamon has become a standalone entity with the release of its version 2.0 and that Debian’s toyed with not going with GNOME for its latest version (7.1 at the time of writing and it picked a good GNOME Shell version in 3.4).

Having had a look at other distribution that already have GNOME Shell 3.8, I knew that a few of my extensions worked with it. The list includes Frippery Bottom Panel, Frippery Move Clock, Places Status Indicator, Removable Drive Menu, Remove Rounded Corners (not really needed with the GNOME Shell theme that I use, Elementary Luna 3.4, but I retain it anyway), Show Desktop Button, User Themes and Ignore_Request_Hide_Titlebar. Because of the changes to the backstage view, I added Frippery Applications Menu in preference to Applications Menu because I have found that to be unstable. Useful new discoveries have included Curtains Up and GNOME Shell Open Terminal while Shell Restart User Menu Entry has made a return and found a use this time around too.

There have been some extensions that were not updated to work with GNOME Shell 3.8 that I have got working. In some cases, it was as simple as updating the metadata.json file for an extension with new version numbers of 3.8 and 3.84 to the list associated with the shell version property. All extensions are to be found in the .local/share/gnome-shell/extensions location in your home directory and each has a dedicated file containing the aforementioned file.

With others, it was a matter of looking in the Looking Glass (execute lg in the box that ALT + F2 brings up on your screen to access this) and seeing what error messages were to be found in there before attempting to correct these in either the extensions’ extension.js files or whatever JavaScript (*.js) file was causing the problem. With either or both of these remedies, I managed to port the four extensions below to GNOME Shell 3.8. In fact, you can download these zip files and install them yourself to see how you get on with them.

Advanced Settings in User Menu

Antisocial Menu

Remove App Menu

Restart Shell Entry

There is a Remove Panel App Menu that works with GNOME Shell 3.8 but I found that it got rid of the Places menu instead of the panel’s App Menu so I tried porting the older extension to see if it behaved itself and it does. With these in place, I have bent Ubuntu GNOME 13.10 to my will ahead of its final release next week and that includes customising Nautilus too. Other than a new version of GNOME Shell, it looks as if it will come with less in the way of drama and a breather like that is no bad thing given that personal computing continues to remain in a state of flux these days.

Changing to web fonts

12th February 2012

While you can add Windows fonts to Linux installations, I have found that their display can be flaky to say the least. Linux Mint and Ubuntu display them as sharp as I’d like but I have struggled to get the same sort of results from Arch Linux while I am not so sure about Fedora or openSUSE either.

That has caused me to look at web fonts for my websites with Google Web Fonts doing what I need with both Open Sans and Arimo doing what I need so far. There have been others with which I have dallied, such as Droid Sans, but these are the ones on which I have settled for now. Both are in use on this website now and I added calls for them to the web page headers using the following code (lines are wrapping due to space constraints):

<link href="http://fonts.googleapis.com/css?family=Open+Sans:300italic,400italic,600italic,700italic,400,300,600,700" rel="stylesheet" type="text/css">
<link href='http://fonts.googleapis.com/css?family=Arimo:400,400italic,700,700italic' rel='stylesheet' type='text/css'>

With those lines in place, it then is a matter of updating font-family and font declarations in CSS style sheets with “Open Sans” or “Arimo” as needed while keeping alternatives defined in case the Google font service goes down for whatever reason. A look at a development release of the WordPress Twenty Twelve theme caused me to come across Open Sans and I like it for its clean lines and Arimo, which was found by looking through the growing Google Web Fonts catalogue, is not far behind. Looking through that catalogue now causes for me a round of indecision since there is so much choice. For that reason, I think it better to be open to the recommendations of others.

A new phone

4th February 2012

After a few years with a straightforward Nokia 1661 and a PAYG Blackberry 8520, I decided to go and upgrade from the former to an HTC Wildfire S. So far, the new phone has been good to me with only a few drawbacks. Other than working out how to insert a SIM card, the phone has been easy to use with just a few nuances to learn, such as finger pinch zooming and dealing with an onscreen keyboard as opposed to a real one.

The touchscreen interface and the 3G capability are the big changes from my Blackberry and both make web browsing so much faster too, especially with the larger screen. For instance, checking RSS feeds with Google Reader and emails is so much faster on the move with the screen being very responsive most of the time that I am using it; it does get dirty like others so either a screen cover or frequent cleaning with a camera lens cloth would be no bad thing. The onscreen keyboard remains something to which I need to grow accustomed and probably is the one area where the Blackberry continues to hold sway though turning the phone sideways and tapping it on the side to change orientation helps a lot. That makes the keys larger and, while my finger are not the thickest, there are fewer cases of hitting the wrong key. Even then, you need to get used to switching between alphabet and numeric keyboards and that applies also when you need punctuation marks like commas and so on.

A new phone

Otherwise, the user interface is bright and pleasing to the eye with the typical presentation of both a clock and current weather on there. Handily, the screen is locked easily too with a press of the button at the top right of the phone. That will put a stop to inadvertent phone calls, emailing, web browsing and other things so it is to be commended. To unlock the screen, all that’s needed is to swipe the lock bar to the bottom. Any alerts are viewed in a similar way with holding down your finger on the top bar presenting an extension that can be pulled all of the way down to see what’s there.

With an icon for the Android Marketplace on the main screen, I got to adding a few apps and you can set these to update automatically too but you need to watch your phone contract’s data allowance. The one for WordPress works better than it does on my Blackberry but it seems that retweeting with UberSocial is much less good on the Android platform. For one thing, feeds for all accounts are presented on the one screen and swiping left to right is needed for replying, retweeting and other operations and that’s not working out so smoothly for me yet. Maybe I’ll try an alternative. There are others that I have downloaded too and these include one from CrossCountry Trains and that seems to be a nice offering even if it failed to find trains between Macclesfield and Edale of a Sunday morning. For those omissions, I have an alternative in place and I also have the LinkedIn app too. That seems to work well too. Usefully, it is possible to move these to the phones microSD card to avoid filling up the limited space that’s on offer. However, that isn’t to say that I will be going mad on these things.

Of course, any phone should be good at making and taking phones and the Wildfire seems to be doing well on this score too. Firstly, contacts were read from the SIM but they can be transferred from an old phone using Bluetooth connections too. Sound is good and loud though you need to be on a call to adjust the speaker volume with the rocker button on the side of the phone. Otherwise, that just changes the volume of the ring tone. Without any adjustments, the phone seems to vibrate and ring at the same time though that may be something that I get to changing in time. The pings emitted when new text messages, emails or tweets fall into the same category.

If there’s any downside to this phone, it has to be battery life. Unlike others that I have had, this is a phone that needs charging every night at the very least. Maybe that’s the price of having a nice bright responsive screen but it would be no harm if it lasted longer. Others have found the same thing and reported as much on the web though some have having worse experiences than others. There are some hints regarding how to conserve battery life but they include such things as switching off 3G or data capabilities and neither appeal to me; after all, I might as well use my old Nokia if this is all that can be offered. Instead, I am wondering if acquiring a spare battery might be no bad idea because that’s what I do for my Pentax DSLR (note in passing: I haven’t got to using the phone’s own camera but recent wintry weather had me tempted by the idea, especially with the likes of Twitpic and YFrog out there.). Taking things further, others have mentioned getting a larger capacity replacement but that sounds more risky.

All in all, first impressions of the HTC Wildfire are good ones. Over time, I should find out more about the ins and outs of the gadget. After all, it is a mini-computer with its own operating system and other software. Since I continue to learn more and more about PC’s everyday, the same should be the case here too.

Changing to CKEditor from FCKEditor for WordPress Content Editing

25th April 2011

The post editor that I have been using on my WordPress-powered outdoors blog has not been TinyMCE but FCKEditor. My use of that editor has meant that WordPress’ autosave and word counting features have not been available to me but that was my choice, as strange as it will sound to some. However, there have been times when I have missed the autosaving functionality and lost work. Since FCKEditor has been replaced by CKEditor, there are plugins available for adding that editor to WordPress’ administration interface. Recently, I got to replacing the old FCKEditor plugin with a newer CKEditor one and that has gained me post or page autosaving. The more cosmetic word counting feature is not active until a draft is manually saved but I can live with that. Other than that, the interface remains familiar with all (X)HTML tags on show in the source code view without any being hidden away from view like in WordPress’ implementation of TinyMCE. That isn’t to see that WordPress is doing something wrong but just that there are alternative way of doing things that are equally valid. After all, why would there be choices if there only ever was one right way to do anything?

Like any WordPress plugins, those replacing the default content editor in WordPress can be vulnerable to changes in the publishing platform and there is one of those in the pipeline for 3.2: a minimalist post/page editor that is billed as being non-distracting. That planned new feature is drawing inspiration from the likes of QuietWrite, where you can write content and transfer it over to WordPress or leave it where it was written. Even with bigger changes like this, my experience never has been that design decisions made for new WordPress releases have restricted to any great extent how I use the thing. That’s not to say that my usage hasn’t changed over time but I have felt that any decisions were mine to make and not all made for me. In that light, I can foresee CKEditor continuing to work on WordPress 3.2 but I’ll be doing some testing ahead of time to be sure that is the case.

Turning off the admin bar in WordPress 3.1

25th October 2010

Work on WordPress 3.1 is in full swing at the moment though I initially though that they were taking a little break after 3.0. From what I can see, many refinements are being made to the multi-blog functionality and behind-the-scenes work is ongoing on the administration screens too.

Another under-the-bonnet change has been to make WordPress less tied to MySQL since the possibility of dropping in support for an alternative such as PostgreSQL is now a reality even if it isn’t part of the default package. For now, it looks as if this is going to be plugin territory rather than default multi-database support though that may become a sensible development in the light of Oracle’s acquisition of MySQL and its sabre rattling with regard to Java patents. So far, the change to WordPress has affected my use of its database engine to power an offline version of my online photo gallery but a quick spot of code editing sorted that issue.

One more obvious alteration is going to be the addition of a WordPress.com style administration bar to the top of all content and administration screens for a user who is logged into the system. It is going to be turned on by default but there will be the option of turning it off for those among who prefer things that way. All that will be needed for this is to add the following line near the top of wp-config.php:

define( “WP_SHOW_ADMIN_BAR”, false);

The chance to see new additions like those above and be ready for is my main reason for following WordPress development. It’s best to be ready than surprised though it has to be said that the blogging or CMS platform is a very polished one these days.

Exploring the mobile web

16th July 2010

With a change of job ahead of me, I decided to make my web usage a little more mobile. The result was the purchase of a Blackberry 8520 Curve on a T-Mobile pay-as-you-go tariff to complement my existing phone. Part of the attraction was having email on the move and a little web access too. On both accounts it hasn’t though GPRS isn’t the speediest for web browsing and you get to appreciating mobile versions of websites. It’s just as well that this website that you’re reading has a mobile version.

Hooking the Blackberry up to GMail was no problem once I had paid my dues and the necessary set up was done for me; it was only then that the required option was available through the set up screens. RIM’s own web browser may be no slouch when it comes to rendering websites but I put Opera Mini in place as well for those times when the default option could be bettered and they exist too. Speaking of RIM applications, there’s one for Twitter too though I added Übertwitter for sake of greater flexibility (it can handle more than one account at a time, for example). In addition, I have instated applications for WordPress and LinkedIn too and it was then that I stopped myself spending too much time in Blackberry App World. If I was of the Facebook persuasion, I might be interested in the default offering for that as well but I have learnt to contain myself.

Of course, there are limitations to the device’s capabilities with regards to email and web on the move. Long emails still need desktop access (messages can get truncated) and mobile unfriendly websites will take an age to load and explore; a small screen means much more finger work. After all, this is a small device so the observations aren’t really surprising; it’s just that I encounter the reality of life on a small screen now. Nevertheless, useful site like those from Google and the Met Office have a mobile variant though I’d like to see the latter including its rain radar as part of the package.

Speaking of life on a smaller scale, there’s the size of the keyboard to consider too. So far, I haven’t had much practice with it but I am unsure as how some craft longer blog entries with the the tiny keys. Then, there’s the ever-present threat of arm discomfort and RSI that you have to watch. For that reason, I’ll stick with use for an hour at a time rather than going mad altogether. Navigating around the screen using the tiny trackpad is something to which I am adjusting and it works well enough too so long as you’re not looking through long web pages or emails.

To bring this piece to a close, the new gadget has been finding uses and I don’t plan on leaving it idle after paying over £150 for it. Apart from acting as an expensive calculator, it has already travelled abroad with me with roaming not being a problem; I may have failed to get it to work with hotel broadband but there was EDGE availability to keep things connected together. All in all, the device is earning its keep and teaching me a few things about mobile handheld computing with my main website in process of being made more mobile compatible with the front page and the photo gallery gaining versions for handheld devices after the same was done for the outdoors blog earlier this year (might make the design look more like the rest of the site though). Without something on which to do some real testing, that idea may not have become reality like it is. It may be no desktop substitute but that’s never to say that these devices may never get near that situation. After all, there was a time when no one could imagine the same for laptop PC’s and we all know what has happened with them.
