Some online writing tools
15th October 2021Every week, I get an email newsletter from Woody’s Office Watch. This was something to which I started subscribing in the 1990’s but I took a break from it for a good while for reasons that I cannot recall and returned to it only in recent years. This week’s issue featured a list of online paraphrasing tools that are part of what is offered by Quillbot, Paraphraser, Dupli Checker and Pre Post Seo. Each got their own reviews in the newsletter so I will just outline other features in this posting.
In Quillbot’s case, the toolkit includes a grammar checker, summary generator, and citation generator. In addition to the online offering, there are extensions for Microsoft Word, Google Chrome, and Google Docs. In addition to the free version, a paid subscription option is available.
In spite of the name, Paraphraser is about more than what the title purports to do. There is article rewriting, plagiarism checking, grammar checking and text summarisation. Because there is no premium version, the offering is funded by advertising and it will not work with an ad blocker enabled. The mention of plagiarism suggests a perhaps murkier side to writing that cuts both ways: one is to avoid copying other work while another is the avoidance of groundless accusations of copying.
It was appear that the main role of Dupli Checker is to avoid accusations of plagiarism by checking what you write yet there is a grammar checker as well as a paraphrasing tool on there too. When I tried it, the English that it produced looked a little convoluted and there is a lack of fluency in what is written on its website as well. Together with a free offering that is supported by ads that were not blocked by my ad blocker, there are premium subscriptions too.
In web publishing, they say that content is king so the appearance of an option using the acronym for Search Engine Optimisation in it name may not be as strange as it might as first glance. There are numerous tools here with both free and paid tiers of service. While paraphrasing and plagiarism checking get top billing in the main menu on the home page, further inspection reveals that there is a lot more to check on this site.
In writing, inspiration is a fleeting and ephemeral quantity so anything that helps with this has to be of interest. While any rewriting of initial content may appear less smooth than the starting point, any help with the creation process cannot go amiss. For that reason alone, I might be tempted to try these tools from time to time and they might assist with proof reading as well because that can be a hit and miss affair for some.
Ditching PC Plus?
28th June 2007When I start to lose interest in the features in a magazine that I regularly buy, then it’s a matter of time before I stop buying the magazine altogether. Such a predicament is facing PC Plus, a magazine that I been buying every month over the last ten years. The fate has already befallen titles like Web Designer, Amateur Photographer and Trail, all of which I now buy sporadically. Returning to PC Plus, I get the impression that it feels more of a lightweight these days. What Future Publishing has been doing over the last decade is add titles to its portfolio that take actually from its long established stalwart; Linux Format and .Net are two that come to mind and there are titles covering Windows Vista and computer music as well. Being a sucker for punishment, I did pick up this month’s PC Plus and the issue is as good an example of the malaise as any. Reviews, once a mainstay of the title, are now less prominent than they were. In place of comparison tests, we now find discussions of topics like hardware acceleration with some reviews mixed in. Topics such as robotics and artificial intelligence do rear their heads in feature articles and I cannot say that I have a great deal of time for such futurology. The tutorials section is still there but has been hived off into a separate mini-magazine and I am not so sure that it has escaped the lightweight revolution. All this is leading me to dump PC Plus in favour of PC Pro from Dennis Publishing. This feels reassuringly more heavyweight and, while the basic format has remained unchanged over the years, it still managed to remain fresh. Reviews, of both software and hardware, are very much in evidence and it manages to have those value-adding feature articles; this month, digital photography and rip-off Britain come under the spotlight. Add the Real Word Computing section and it all makes a good read in these times of behemoths like Microsoft, Apple and Adobe delivering new things on the technology front. I don’t know if I have changed but PC Pro does seem better than PC Plus these days.
Getting VirtualBox working on Ubuntu after a kernel upgrade
27th July 2008In previous posts, I have talked about getting VMware Workstation back on its feet again after a kernel upgrade. It also seems that VirtualBox is prone to the same sort of affliction. However, while VMware Workstation fails to start at all, VirtualBox at least starts itself even if it cannot get a virtual machine going and generates errors instead.
My usual course of action is to fire up Synaptic and install the drivers for the relevant kernel. Looking for virtualbox-ose-modules-[kernel version and type] and installing that usually resolves the problem. For example, at the time of writing, the latest file available for my system would be virtualbox-ose-modules-2.6.24-19-generic. If you are a command line fan, the command for this would be:
sudo apt-get install virtualbox-ose-modules-2.6.24-19-generic
The next thing to do would be to issue the command to start the vboxdrv service and you’d be all set:
sudo /etc/init.d/vboxdrv start
There is one point of weakness (an Achilles heal, if you like) with all of this: the relevant modules need to be available in the first place and I hit a glitch after updating the kernel to 2.6.24-20 when they weren’t; I do wonder why Canonical fail to keep both in step with one another and why the new kernel modules don’t come through the updates automatically either. However, there is a way around this too. That means installing virtualbox-ose-source via either Synaptic or the command line:
sudo apt-get install virtualbox-ose-source
The subsequent steps involve issuing more commands to perform a reinstallation from the source code:
sudo m-a prepare
sudo m-a auto-install virtualbox-ose
Once these are complete, the next is to start the vbox drv as described earlier and to add yourself to vboxusers group if you’re still having trouble:
sudo adduser [your username] vboxusers
The source code installation option certainly got me up and running again and I’ll be keeping it on hand for use should the situation raise its head again.
Piggybacking an Android Wi-Fi device off your Windows PC’s internet connection
16th March 2013One of the disadvantages of my Google/Asus Nexus 7 is that it needs a Wi-Fi connection to use. Most of the time this is not a problem since I also have a Huawei mobile WiFi hub from T-Mobile and this seems to work just about anywhere in the U.K. Away from the U.K. though, it won’t work because roaming is not switched on for it and that may be no bad thing with the fees that could introduce. My HTC Desire S could deputise but I need to watch costs with that too.
There’s also the factor of download caps and those apply both to the Huawei and to the HTC. Recently, I added Anquet‘s Outdoor Map Navigator (OMN) to my Nexus 7 through the Google Play store for a fee of £7 and that allows access to any walking maps that I have bought from Anquet. However, those are large downloads so the caps start to come into play. Frugality would help but I began to look at other possibilities that make use of a laptop’s Wi-Fi functionality.
Looking on the web, I found two options for this that work on Windows 7 (8 should be OK too): Connectify Hotspot and Virtual Router Manager. The first of these is commercial software but there is a Lite edition for those wanting to try it out; that it is not a time limited demo is not something that I can confirm though that did not seem to be the case since it looked as if only features were missing from it that you’d get if you paid for the Pro variant. The second option is an open source one and is free of charge apart from an invitation to donate to the project.
Though online tutorials show the usage of either of these to be straightforward, my experiences were not all that positive at the outset. In fact, there was something that I needed to do and that is why this post has come to exist at all. That happened even after the restart that Conectify Hotspot needed as part of its installation; it runs as a system service so that’s why the restart was needed. In fact, it was Virtual Router Manager that told me what the issue was and it needed no reboot. Neither did it cause network disconnection of a laptop like the Connectify offering did on me and that was the cause of its ejection from that system; limitations in favour of its paid addition aside, it may have the snazzier interface but I’ll take effective simplicity any day.
Using Virtual Router Manager turns out to be simple enough. It needs a network name (also known as an SSID), a password to restrict who accesses the network and the internet connection to be shared. In my case, the was Local Area Connection on the drop down list. With all the required information entered, I was ready to start the router using the Start Network Router button. The text on this changes to Stop Network Router when the hub is operational or at least it should have done for me on the first time that I ran it. What I got instead was the following message:
The group or resource is not in the correct state to perform the requested operation.
The above may not say all that much but it becomes more than ample information if you enter it into the likes of Google. Behind the scenes, Virtual Router Manager is using native Windows functionality is create a WiFi hub from a PC and it appears to be the Microsoft Virtual Wi-Fi Miniport Adapter from what I have seen. When I tried setting up an adhoc Wi-Fi network from a laptop to the Nexus 7 using Windows’ own network set up capability via its Control Panel, it didn’t do what I needed so there might be something that third party software can do. So, the interesting thing about the solution to my Virtual Router Manager problem was that it needed me to delve into the innards of Windows a little.
Firstly, there’s running Command Prompt (All Programs > Accessories) from the Start Menu with Administrator privileges. It helps here if the account with which you log into Windows is in the Administrators group since all you have to do then is right click on the Start Menu entry and choose Run as administrator entry in the pop-up context menu. With a command line window now open, you then need to issue the following command:
netsh wlan set hostednetwork mode=allow ssid=[network name] key=[password] keyUsage=persistent
When that had done its thing, Virtual Router Manager worked without a hitch though it did turn itself after a while and that may be no bad thing from the security standpoint. On the Android side, it was a matter of going in Settings > Wi-Fi and choose the new network that have been creating on the laptop. This sort of thing may apply to other types of tablet (Dare I mention iPads?) so you could connect anything to the hub without needing to do any more on the Windows side.
For those wanting to know what’s going on behind the scenes on Windows, there’s a useful tutorial on Instructables that shows what third party software is saving you from having to do. Even if I never go down the more DIY route, I probably have saved myself having to buy a mobile Wi-Fi hub for any trips to Éire. For now, the Irish 3G dongle that I already have should be enough.
Tidying dynamic URL’s
15th June 2007A few years back, I came across a very nice article discussing how you would make a dynamic URL more palatable to a search engine and I made good use of its content for my online photo gallery. The premise was that URL’s that look like that below are no help to search engines indexing a website. Though this is received wisdom in some quarters, it doesn’t seem to have done much to stall the rise of WordPress as a blogging platform.
http://www.mywebsite.com/serversidescript.php?id=394
That said, WordPress does offer a friendlier URL display option too and you can see this in use on this blog; they look a little like the example URL that you see below, and the approach is equally valid for both Perl and PHP. I have been using the same approach for the Perl scripts powering my online phone gallery and now want to apply the same thinking to a gallery written in PHP:
http://www.mywebsite.com/serversidescript.pl/id/394
The way that both expressions work is that a web server will chop pieces from a URL until it reaches a physical file. For a query URL, the extra information after the question mark is retained in its QUERY_STRING variable while extraneous directory path information is passed in the variable PATH_INFO. For both Perl and PHP, these are extracted from the entries in an array; for Perl, this array is called is $ENV and $_SERVER is the PHP equivalent. Thus, $ENV{QUERY_STRING} and $_SERVER{‘QUERY_STRING’} traps what comes after the “?” while $ENV{PATH_INFO} and $_SERVER{‘PATH_INFO’} picks up the extra information following the file name (the “/id/394/” in the example). From there on, the usual rules apply regarding cleaning of any input but changing from one to another should be too arduous.
Upgrading from Windows 7 to Windows 8 in a VMWare Virtual Machine
1st November 2012Though my main home PC runs Linux Mint, I do like to have the facility to use Windows software from time to time and virtualisation has allowed me to continue doing that. For a good while, it was a Windows 7 guest within a VirtualBox virtual machine and, before that, one running Windows XP fulfilled the same role. However, it did feel as if things were running slower in VirtualBox than once might have been the case and I jumped ship to VMware Player. It may be proprietary and closed source but it is free of charge and has been doing what was needed. A subsequent recent upgrade of video driver on the host operating system allowed the enabling of a better graphical environment in the Windows 7 guest.
Instability
However, there were issues with stability and I lost the ability to flit from the VM window to the Linux desktop at will with the system freezing on me and needing a reboot. Working in Windows 7 using full screen mode avoided this but it did feel as I was constrained to working in a Windows machine whenever I did so. The graphics performance was imperfect too with screening refreshing being very blocky with some momentary scrambling whenever I opened the Start menu. Others would not have been as patient with that as I was though there was the matter of an expensive Photoshop licence to be guarded too.
In hindsight, a bit of pruning could have helped. An example would have been driver housekeeping in the form of removing VirtualBox Guest Additions because they could have been conflicting with their VMware counterparts. For some reason, those thoughts entered my mind and I was pondering another more expensive option instead.
Considering NAS & Windows/Linux Networking
That would have taken the form of setting aside a PC for running Windows 7 and having a NAS for sharing files between it and my Linux system. In fact, I did get to exploring what a four bay QNAP TS-412 would offer me and realised that you cannot put normal desktop hard drives into devices like that. For a while, it looked as if it would be a matter of getting drives bundled with the device or acquiring enterprise grade disks so as to main the required continuity of operation. The final edition of PC Plus highlighted another one though: the Western Digital Red range. These are part way been desktop and enterprise classifications and have been developed in association with NAS makers too.
Looking at the NAS option certainly became an education but it has exited any sort of wish list that I have. After all, there is the cost of such a setup and it’s enough to get me asking if I really need such a thing. The purchase of a Netgear FS 605 ethernet switch would have helped incorporate it but there has been no trouble sorting alternative uses for it since it bumps up the number of networked devices that I can have, never a bad capability to have. As I was to find, there was a less expensive alternative that became sufficient for my needs.
In-situ Windows 8 Upgrade
Microsoft have been making available evaluation copies of Windows 8 Enterprise that last for 90 days before expiring. One is in my hands has been running faultlessly in a VMware virtual machine for the past few weeks. That made me wonder if upgrading from Windows 7 to Windows 8 help with my main Windows VM problems. Being a curious risk-taking type I decided to answer the question for myself using the £24.99 Windows Pro upgrade offer that Microsoft have been running for those not needing a disk up front; they need to pay £49.99 but you can get one afterwards for an extra £12.99 and £3.49 postage if you wish, a slightly cheaper option. There also was a time cost in that it occupied a lot of a weekend on me but it seems to have done what was needed so it was worth the outlay.
Given the element of risk, Photoshop was deactivated to be on the safe side. That wasn’t the only pre-upgrade action that was needed because the Windows 8 Pro 32-bit upgrade needs at least 16 GB before it will proceed. Of course, there was the matter of downloading the installer from the Microsoft website too. This took care of system evaluation and paying for the software as well as the actual upgrade itself.
The installation took a few hours with virtual machine reboots along the way. Naturally, the licence key was needed too as well as the selection of a few options though there weren’t many of these. Being able to carry over settings from the pre-exisiting Windows 7 instance certainly helped with this and with making the process smoother too. No software needed reinstatement and it doesn’t feel as if the system has forgotten very much at all, a successful outcome.
Post-upgrade Actions
Just because I had a working Windows 8 instance didn’t mean that there wasn’t more to be done. In fact, it was the post-upgrade sorting that took up more time than the actual installation. For one thing, my digital mapping software wouldn’t work without .Net Framework 3.5 and turning on the operating system feature form the Control Panel fell over at the point where it was being downloaded from the Microsoft Update website. Even removing Avira Internet Security after updating it to the latest version had no effect and it was a finding during the Windows 8 system evaluation process. The solution was to mount the Windows 8 Enterprise ISO installation image that I had and issue the following command from a command prompt running with administrative privileges (it’s all one line though that’s wrapped here):
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:\sources\sxs /LimitAccess
For sake of assurance regarding compatibility, Avira has been replaced with Trend Micro Titanium Internet Security. The Avira licence won’t go to waste since I have another another home in mind for it. Removing Avira without crashing Windows 8 proved impossible though and necessitating booting Windows 8 into Safe Mode. Because of much faster startup times, that cannot be achieved with a key press at the appropriate moment because the time window is too short now. One solution is to set the Safe Boot tickbox in the Boot tab of Msconfig (or System Configuration as it otherwise calls itself) before the machine is restarted. There may be others but this was the one that I used. With Avira removed, clearing the same setting and rebooting restored normal service.
Dealing with a Dual Personality
One observer has stated that Windows 8 gives you two operating systems for the price of one: the one in the Start screen and the one on the desktop. Having got to wanting to work with one at a time, I decided to make some adjustments. Adding Classic Shell got me back a Start menu and I left out the Windows Explorer (or File Explorer as it is known in Windows 8) and Internet Explorer components. Though Classic Shell will present a desktop like what we have been getting from Windows 7 by sweeping the Start screen out of the way for you, I found that this wasn’t quick enough for my liking so I added Skip Metro Suite to do this and it seemed to do that a little faster. The tool does more than sweeping the Start screen out of the way but I have switched off these functions. Classic Shell also has been configured so the Start screen can be accessed with a press of Windows key but you can have it as you wish. It has updated too so that boot into the desktop should be faster now. As for me, I’ll leave things as they are for now. Even the possibility of using Windows’ own functionality to go directly to the traditional desktop will be left untested while things are left to settle. Tinkering can need a break.
Outcome
After all that effort, I now have a seemingly more stable Windows virtual machine running Windows 8. Flitting between it and other Linux desktop applications has not caused a system freeze so far and that was the result that I wanted. There now is no need to consider having separate Windows and Linux PC’s with a NAS for sharing files between them so that option is well off my wish-list. There are better uses for my money.
Not everyone has had my experience though because I saw a report that one user failed to update a physical machine to Windows 8 and installed Ubuntu instead; they were a Linux user anyway even if they used Fedora more than Ubuntu. It is possible to roll back from Windows 8 to the previous version of Windows because there is a windows.old directory left primarily for that purpose. However, that may not help you if you have a partially operating system that doesn’t allow you to do just that. In time, I’ll remove it using the Disk Clean-up utility by asking it to remove previous Windows installations or running File Explorer with administrator privileges. Somehow, the former approach sounds the safer.
What About Installing Afresh?
While there was a time when I went solely for upgrades when moving from one version of Windows to the next, the annoyance of the process got to me. If I had known that installing the upgrade twice onto a computer with a clean disk would suffice, it would have saved me a lot. Staring from Windows 95 (from the days when you got a full installation disk with a PC and not the rescue media that we get now) and moving through a sequence of successors not only was time consuming but it also revealed the limitations of the first in the series when it came to supporting more recent hardware. It was enough to have me buying the full retailed editions of Windows XP and Windows 7 when they were released; the latter got downloaded directly from Microsoft. These were retail versions that you could move from one computer to another but Windows 8 will not be like that. In fact, you will need to get its System Builder edition from a reseller and that can only be used on one machine. It is the merging of the former retail and OEM product offerings.
What I have been reading is that the market for full retail versions of Windows was not a big one anyway. However, it was how I used to work as you have read above and it does give you a fresh system. Most probably get Windows with a new PC and don’t go building them from scratch like I have done for more than a decade. Maybe the System Builder version would apply to me anyway and it appears to be intended for virtual machine use as well as on physical ones. More care will be needed with those licences by the looks of things and I wonder what needs not to be changed so as not to invalidate a licence. After all, making a mistake might cost between £75 and £120 depending on the edition.
Final Thoughts
So far Windows 8 is treating me well and I have managed to bend to my will too, always a good thing to be able to say. In time, it might be that a System Builder copy could need buying yet but I’ll leave well alone for now. Though I needed new security software, the upgrade still saved me money over a hardware solution to my home computing needs and I have a backup disk on order from Microsoft too. That I have had to spend some time settling things was a means of learning new things for me but others may not be so patient and, with Windows 7 working well enough for most, you have to ask if it’s only curious folk like me who are taking the plunge. Still, the dramatic change has re-energised the PC world in an era when smartphones and tablets have made so much of the running recently. That too is no bad thing because an unchanging technology is one that dies and there are times when big changes are needed, as much as they upset some folk. For Microsoft, this looks like one of them and it’ll be interesting to see where things go from here for PC technology.
Mobile Phones
7th November 2010
For a long time, I wasn’t that interested in mobile telephony but a switch of job in 2010 meant that having access to the web from a mobile became desirable so I started doing that with a long relinquished BlackBerry Curve 8520; now it is Motorola hardware that I mainly use for the same kind of thing. The increased interest in mobile telephony has borne fruit in the list that you find here. The world of 3G and the devices that use it produced a learning curve for me and the availability of 5G is growing now too.
One thing that you’ll see from many a high street in the U.K. is the profusion of shops operated by mobile phone network operators and it is the same in Éire (the indigenous operator Eir has impressed me over there). These networks sell you their wares online too and that is why they are listed in their own section at the bottom. Before their listing, I have collected whatever retailers there are that are not attached to any network and there didn’t seem to be that many of them when I set up the list but it’s grown a good bit since then due to my perusing the occasional mobile phone magazine. If I find any more of these, I’ll add them on here.
Independent Retailers
These are the people with whom I have had the most dealings since I got my first ever mobile phone from them, a Motorola that I kept using until it battery kept losing its charge quickly on me. More recently, I picked up a Nokia 1661 from them that needed a look at the manual to get its call volume set properly.
If these didn’t sponsor the Buyer’s Guide in Smartphone Essentials magazine, I never would have heard of them; Derby County FC supporters should have seen their logo on the player’s shirts but I cannot say that I am a football fan. A look at the website confirms the presence of a comprehensive selection of phones for sale, contracted or otherwise.
Compared to the others, this outlet is unusual in offering only phones without contracts or pay-as-you-go arrangements. In other words, it is a place for someone running the gauntlet of the cost of going for a SIM-free phone. Saying that, they have their place and many tariffs are puffed up to pay for the more expensive device that is provided to you as part of the contract; that’s why you are tied in for a certain length of time too, so as ensure that the cost of the phone is recovered.
The name may be new to me but its Derbyshire based parent company has been involved in mobile phone reselling for more than a decade. The range that the website supplies includes not controlled contracted and pay as you go phones but also SIM cards and phones without SIM cards. That makes it worth a look along with others like it.
Networks
Haven’t had much to do with these people apart from poking around their website looking at what SIM-only deals that they have. However, hearing the experiences of others with their network takes the shine off their offer.
From the point of view of network coverage, this operator looks like your best option and would be who I would choose if I had my chance again; there have been parts of Wales and Scotland where I otherwise not have had mobile signal with my O2 account and Vodafone users were left bereft in the case of the Welsh location of Port Eynon. It was a T-Mobile PAYG BlackBerry Curve 8520 that brought me their way in 2010 and the merger with Orange soon showed its advantages when it came to network improvements. A PAYG mobile WiFi modem followed in 2011 and that uses the SIM card from a defunct Huawei mobile broadband dongle. The BlackBerry was traded for cash once a phone upgrade made available an older HTC to replace the thing; it was hideously slow and that may have had more to do with the phone that its 2G data connection. More recently, a backup Moto makes use of a PAYG account and that is how things look for now.
As it happens, I have been with this bunch since they were part of BT and known as Cellnet. The transformation to O2 and subsequent incorporation into Telefonica and Virgin Media has not meant any disruption. Their BT origins and being part of the first wave of operators has meant that network coverage is reasonable too, though voice services do come out better than data ones so that needs to be kept in mind.
For a global operator, their British and Irish networks leave something to be desired and the British one got slated in an industry appraisal. That fits with the pay-as-you-go mobile broadband dongle experience in the U.K. as well as hit and miss attempts calling Vodafone network users in Ireland. Let’s hope that those network problems get sorted because good phones need equally good connections.
An in situ upgrade to Linux Mint 12
4th December 2011Though it isn’t the recommended approach, I have ended up upgrading to Linux Mint 12 from Linux Mint 11 using an in situ route. Having attempted this before with a VirtualBox hosted installation, I am well aware of the possibility of things going wrong. Then, a full re-installation was needed to remedy the situation. With that in mind, I made a number of backups in the case of an emergency fresh installation of the latest release of Linux Mint. Apache and VirtualBox configuration files together with MySQL backups were put where they could be retrieved should that be required. The same applied to the list of installed packages on my system. So far, I haven’t needed to use these, but there is no point in taking too many chances.
The first step in an in-situ Linux Mint upgrade is to edit /etc/apt/sources.list. In the repository location definitions, any reference to katya (11) was changed to lisa (for 12) and the same applied to any appearance of natty (Ubuntu 11.04) which needed to become oneiric (Ubuntu 11.10). With that done, it was time to issue the following command (all one line even if it is broken here):
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
Once that had completed, it was time to add the new additions that come with Linux Mint 12 to my system using a combination of apt-get, aptitude and Synaptic; the process took a few cycles. GNOME already was in place from prior experimentation, so there was no need to add this anew. However, I need to instate MGSE to gain the default Linux Mint customisations of GNOME 3. Along with that, I decided to add MATE, the fork of GNOME 2. That necessitated the removal of two old libraries (libgcr0 and libgpp11, if I recall correctly but it will tell you what is causing any conflict) using Synaptic. With MGSE and MATE in place, it was time to install LightDM and its Unity greeter to get the Linux Mint login screen. Using GDM wasn’t giving a very smooth visual experience and Ubuntu, the basis of Linux Mint, uses LightDM anyway. Even using the GTK greeter with LightDM produced a clunky login box in front of a garish screen. Configuration tweaks could have improved on this but it seems that using LightDM and Unity greeter is what gives the intended setup and experience.
With all of this complete, the system seemed to be running fine until the occasional desktop freeze occurred with Banshee running. Blaming that, I changed to Rhythmbox instead, though that helped only marginally. While this might be blamed on how I upgraded my system, things seemed to have steadied themselves in the week since then. As a test, I had the music player going for a few hours and there was no problem. With the call for testing of an update to MATE a few days ago, it now looks as if there may have been bugs in the original release of Linux Mint 12. Daily updates have added new versions of MGSE and MATE so that may have something to do with the increase in stability. Even so, I haven’t discounted the possibility of needing to do a fresh installation of Linux Mint 12 just yet. However, if things continue as they are, then it won’t be needed and that’s an upheaval avoided should things go that way. That’s why in situ upgrades are attractive though rolling distros like Arch Linux (these words are being written on a system running this) and LMDE are more so.
A belated goodbye to PC Plus magazine
13th October 2012Last year, Future Publishing made a loss so something had to be done to address that. Computer magazines such as Linux Format no longer could enclose their cover-mounted discs in elaborate cardboard wallets and moved to simpler sleeves instead. Another casualty has been one of their longest standing titles: PC Plus.
It has been around since 1986 and possibly was one of the publisher’s first titles. It was the late nineties when I first encountered and, for quite a few years afterwards, it was my primary computer magazine of choice every month. The mix of feature articles, reviews and tutorials covering a variety of aspects of personal computing was enough for me. After a while though, it became a bit stale and I stopped buying it regularly. Then, the collection that I had built up was dispatched to the recycling bin and I turned to other magazines.
In the late nineties, Future had a good number of computing titles on magazine shelves in newsagents and there did seem to be some overlap in content. For instance, we had PC Answers and PC Format alongside PC Plus at one point. Now, only PC Format is staying with us and its market seems to be high home computer users such as those interested in PC gaming. .Net, initially a web usage title and now one focussing on website design and development, started from the same era and Linux Format dates from around the turn of the century. Looking back, it looks there was a lot of duplication going on in a heady time of expanding computer usage.
That expansion may have killed off PC Plus in the end. For me, it certainly meant that it no longer was a one stop shop like Dennis’s PC Pro. For instance, the programming and web design content that used to come in PC Plus found itself appearing in .Net and in Linux Format. The appearance of the latter certainly meant that was somewhere else for Linux content; for the record, my first dalliance with SuSE Linux was from a PC Plus cover-mounted disk. The specialisation and division certainly made PC Plus a less essential read than I once thought it.
Of course, we now have an economic downturn and major changes in the world of publishing alongside it. Digital publishing certainly is growing and this isn’t just about websites anymore. That probably explains in part Future’s recent financial performance. Then, when a title like PC Plus is seen as less important, then it can cease to exist but I reckon that it’s the earlier expansion that really did for it. If Future had one computing title that contained extensive reviews and plenty of computing tutorials with sections of programming and open source software, who knows what may have happened. Maybe consolidating the other magazines into that single title would have been an alternative but my thinking is that it wouldn’t have been commercially realistic. Either way, the present might have be very different and PC Plus would be a magazine that I’d be reading every month. That isn’t the case of course and it’s sad to see it go from newstands even if the reality was that it left us quite a while ago in reality.
The wonders of mod_rewrite
24th June 2007When I wrote about tidying dynamic URL’s a little while back, I had no inkling that that would be a second part to the tale. My discovery of mod_rewrite, an Apache module that facilitates URL translation. The effect is that one URL is presented to the user in the browser address bar, and the exact same URL is also seen by search engines, while another is passed to the server for processing. It might sound like subterfuge but it works very well once you manage to get it set up properly. The web host for my hillwalking blog/photo gallery has everything configured such it is ready to go but the same did not apply to the offline Apache 2.2.x server that I have going on my own Windows XP box. There were two parts to getting it working there:
- Activating mod-rewrite on the server: this is as easy as uncommenting a line in the httpd.conf file for the site (the line in question is: LoadModule rewrite_module modules/mod_rewrite.so).
- Ensuring that the .htaccess file in the root of the web server directory is active. You need to set the values of the AllowOverride directives for the server root and CGI directories to All so that .htaccess is active. Not doing it for the latter will result in the an error beginning with the following: Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden. Having Allow from All set for the required directories is another option to consider when you see errors like that.
Once you have got the above sorted, adding this line to .htaccess: RewriteEngine On. Preceding it with an Options directive to ensure that FollowSymLinks and SymLinksIfOwnerMatch are switched on does no harm at all and may even be needed to get things running. That done, you can set about putting mod_write to work with lines like this:
RewriteRule ^pages/(.*)/?$ pages.php?query=$1
The effect of this is to take http://www.website.com/pages/input and convert it into a form for action by the server; in this case, that is http://www.website.com/pages.php?query=input. Anything contained by a bracket is assigned to the value of a system-named variable. If you have several bracketed sections, they are assigned to sequentially numbered variables as follows: $1 for the first, $2 for the second and so on. It’s all good stuff when you get it going and not only does it make things look much neater but it also possesses an advantage when it comes to future-proofing too. Web addresses can be kept constant over time, even if things change behind the scenes. It means that returning visitors will find what they saw the last time that they visited and surely must ensure good karma in eyes of those all important search engines.
