A tale of two reviews

21st June 2007

Olympus E-410

Recently, I encountered two very different reviews of the newly launched Olympus E-410 DSLR in Which Digital Camera? and Practical Photography, respectively. The review in the former was a positive affair, though it was a first look at the camera, but the impression formed by the latter reviewer was lukewarm in nature.

The camera features a live electronic viewer on its back, a carry over from digital compacts and a feature that I may never use. While that might be the unique selling point for the camera, good image quality and the fact that it possesses a cleaning mechanism for its sensor are of much more interest to me.

Ironically, the Practical Photography review spent most of its time talking about the very feature of the camera that interests me the least, with only a scant mention of quality; to be frank, I didn’t find it a very useful appraisal even if the electronic viewfinder may not be all that it’s cracked up to be and it’s picture quality and camera handling that ultimately matter to the photography enthusiast.

In contrast, Which Digital Camera? seemed to give a more rounded view and proved to be of more interest and I’d be interested to see what the likes of Photography Monthly and Amateur Photographer might have to say. Incidentally, I also shall be awaiting the Which Digital Camera? appraisal of Ricoh’s Caplio GX100 in their next issue.

Network Assisted Storage Distros

2nd November 2023

For a long time, I was under the impression that any operating system catering for Network Assisted Storage servers either came with the devices or was based on BSD. A review in Linux Voice changed that understanding and a spare PC was set up using OpenMediaVault.

Previously, I had tried FreeNAS with no success because the installation CD’s that I had made would not boot up the machine, most likely because it did not have an Intel processor. FreeNAS is now TrueNAS but the BSD basis remains and that puts it into the UNIX, so it is listed among those rather than these Linux-based options.

EasyNAS

This is based on openSUSE and it displays its reason for existence in its name. Thankfully, it is as easy to use as it intends to be and there is more on this in a Linux Magazine review.

Openfiler

This largely is a commercial offering, though there is a community edition as well. Support for the latter apparently is lacking, which tells its own story.

OpenMediaVault

After positive comments from Linux Voice, I went and gave this a go. It is based on Debian, so there was a certain familiarity with the underpinnings anyway. Once I had watched a video on YouTube, the interface became clearer and I was able to make it work as it should. There are plugins too, so functionality can be extended with the likes of ownCloud and other tools. OMV-EXTRAS.ORG has a good selection that adds to the ones included in the standard installation. It still runs my cold backup system (it is switched off when no backups are being made) to this very day.

RockStor

It may sell itself more as being a cloud server but it also can act as a NAS too and it is good to have a range of possibilities. The file system is BTRFS rather than EXT4, which normally is used with Linux, but that is done with the intent of offering features comparable to ZFS for more solid file storage.

Turnkey Linux

It is the File Server variant that would power a NAS, but it does look like that are a lot of interesting other possibilities available from the website; there are ones for WordPress, Drupal and Joomla!, for instance. Debian is the basis for this one too.

Resolving Windows Update Error 0x80244019 on Windows 10

21st August 2015

In Windows 10, the preferred place to look if you fancy prompting an update of the system is in the Update & Security section of the Settings application. At the top is the Windows Update and the process usually is as simple as pressing the Check for updates button. For most of the time, that has been my experience but it stopped working on my main Windows 10 virtual machine so I needed to resolve the problem.

Initially, going into the Advanced Options section and deselecting the tick box for Give me updates for other Microsoft products when I update Windows helped but it seemed a non-ideal solution so I looked further. It was then that I found that manually resetting a system’s Windows Updates components helped others so I tried that and restarted the system.

The first part of the process was to right-click on the Start Menu button and select the Windows PowerShell (Admin) entry from the menu that appeared. This may be replaced by Command Prompt (Admin) on your system on your machine, but the next steps in the process are the same. In fact, you could include any commands you see below in a script file and execute that if you prefer. Here, I will run through each group in succession.

From either PowerShell or the Command Prompt, you need to stop the Windows Update, Cryptographic, BITS (or Background Intelligent Transfer Service) and MSI Installer services. To accomplish this, execute the following commands at a command prompt:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver

With the services stopped, it is then possible to rename the SoftwareDistribution and Catroot2 folders so you can refresh everything to remove them. To accomplish this, execute the following pair of commands using either PowerShell or the Command Prompt:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old

Once you have the folders renamed, then you can start the Windows Update, Cryptographic, BITS and MSI Installer services by executing the following commands in either PowerShell or the Command Prompt:

net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Once these have completed, you may close the PowerShell or Command Prompt window that you were using and restart the machine. Going into the Update & Security section of the Settings tool afterwards and pressing the Check for updates button now builds new versions of the folders that you renamed and this takes a little while longer than the usual update process. Otherwise, you could let your system rebuild things in its own time. As it happens, I opted for manual intervention and all has worked well since then.

Using the Windows Command Line for Security Administration

24th July 2009

While there are point and click tools for the job, being able to set up new user groups, attaching them to folders and assign uses to them using the command line has major advantages when there are a number to be set up and logs of execution can be retained too. In light of this, it seems a shame that terse documentation along with its being hard to rack down answers to any questions using Google, or whatever happens to be your search engine of choice, makes it less easy to discern what commands need to be run. This is where a book would help but the whole experience is in direct contrast to the community of information providers that is the Linux user community, with Ubuntu being a particular shining example. Saying that, the Windows help system is not so bad once you can track down what you need. For instance, knowing that you need commands like CACLS and NET LOCALGROUP, the ones that have been doing the back work for me, it offers useful information quickly enough. To illustrate the usefulness of the aforementioned commands, here are a few scenarios.

Creating a new group:

net localgroup [name of new group] /comment:”[more verbose description of new group]” /add

Add a group to a folder:

cacls [folder address] /t /e /p [name of group]

The /t switch gets cacls to apply changes to the ACL for the specified folder and all its subfolders, recursive action in other words, while the /e specifies ACL editing rather than its replacement and /p induces replacement of permissions for a given user or group. Using :n, :f, :c or :r directly after the name of a specified user or group assigns no, full, change (write) or read access, respectively. Replacing /p with /r revokes access and leaving off the :n/:f/:c/:r will remove the group or user from the folder.

Add a user to a group:

net localgroup [name of group] [user name (with domain name if on a network)] /add

In addition to NET LOCALGROUP, there is also NET GROUP for wider network operations, something that I don’t have cause to do. Casting the thinking net even wider, I suspect that VB scripting and its ability to tweak the Windows Management Interface might offer more functionality than what is above (PowerShell also comes to mind while we are on the subject) but I am sharing what has been helping me and it can be hard to find if you don’t know where to look.

Pondering storage options

1st June 2011

The combination of curiosity and a little spare time had me browsing online computing technology stores recently. A spot of CD and DVD burning brought on by a flurry of Linux distribution testing reminded me of the possibility. Because I have built up a sizeable library of digital photos, ensuring that I have backups of them is something that needs doing. A 2 GB Samsung external hard drive is brought to life every now and again for that purpose but the prospect of using Blu-Ray discs has appealed to me. After all capacities of 25 GB for single layer discs and 50 GB for dual layer ones sound not inappropriate for my purposes. However, they aren’t a cheap option at the time of writing with each disc costing in the region of £3-4 at one place where I was looking. The cost of BD writers themselves seems not to be so bad though with a few in the £60-100 bracket; any lower than this and you could end up with a combo drive that reads Blu-Ray discs and writes to DVD’s and CD’s so a modicum of concentration is needed. As attractive as the idea might be, the cost of BD media means that I’ll wait a little while before deciding to take the plunge. The price premium at the moment is a reminder of the way that things used to be when CD and DVD writers first came on the market. It is very telling when discs come packaged in jewel cases, something that you won’t see too often with CD’s or DVD’s.

Another piece of storage excitement that hasn’t escaped me is the advent of SSD hard drives. With no moving parts like in conventional hard drives, they bring a speed boost. Concerns about their lifetimes and the numbers of read/write events per drive would stall me when it comes to storing personal data on them but using them for the likes of operating system files sounds attractive, especially with my partiality to Linux perhaps not hammering drives so much. As with any new technology, there is a price premium though a drive big enough for hosting an operating system can be acquired for less than £100. As with many of my hardware purchase brainwaves, there’s no rush but this is an option that I’ll keep at the back of my mind.

Another appealing notion is the idea of getting a NAS so that files can be shared between a few computers. While I have seen prices starting at just above £70 for single disk enclosures, these generally are a more expensive option than external drives and that’s before you consider the cost of any hard drives. Nevertheless, the advantages of a unit containing more than a single hard drive while operating as a print server for any compatible printer too. When you get to 4 or 5 hard drive trays, then the cost has mounted but that could be when they pay their way too. What reminded me of these was a bookazine on home networking that I recently found at a branch of WHSmith’s and their attractions are subject to the networking side of things being made to work without a drama. Once that’s out of the way, then their usefulness really does appeal.

Mulling over all these brainwaves is one thing but it doesn’t mean that the purse strings will become too loose in this age of economic constraint. In fact, pondering them may serve to staunch any impulse purchases. Sometimes, a spot of virtual shopping serves to control things rather than losing the run of oneself.

More Linux Distributions

21st September 2012

More Linux Distributions

If a certain Richard Stallman had his way, Linux would be called GNU/Linux because he wants GNU to have some of the credit, but we’re lazy creatures and we all call it Linux instead. What still amazes me is the number of Linux distributions that are out there. This list captures those that do not fit into other lists that you can find in the sidebar, so do look at the others as well.

Many fit into the desktop and server computing paradigms while a minority are very distinctive. It is easier to write about the latter than the former, though personal experiences do add to any narrative. It is tempting to think that everything has become static after more than thirty years, yet that may be foolish given the ongoing flux in the world of technology. Only change is ever a constant presence.

More in the Way of Privacy

The controversy about security agencies eavesdropping on internet communications has upset some and here are some distros offering anonymity and privacy. Of course, none of these should be used for unlawful purposes since there are those in less liberal countries who need invisibility to speak their minds.

Qubes OS

It is harder and harder to create a Linux distro that is very different from the rest, but this one uses application virtualisation for added security. You can organise your software into different domains so that you work more securely when moving data between applications from different domains.

Robolinux

There is more than a hint of privacy-mindedness in this distro when you look long enough at what it offers. Cinnamon, MATE and Xfce desktop environments are part of the offer and there is added software for extra privacy and security.

Tails

This is an option for those who are worried about being tracked online. All internet connections are sent via the Tor network and it is run exclusively as a live distro from CD, DVD or USB stick drive too, so no trace is left on any PC. The basis is Debian and the distro’s name is an acronym: The Amnesiac Incognito Live System. For us living in a democratic country, the effort may seem excessive but that changes in other places where folk are not so fortunate. The use of Tor may not be perfect but it should help in combination with the use of different sessions for different tasks and encrypting any files. There even is an option to make the desktop appear like that of Windows XP for extra discreteness of use.

Whonix

Most Linux distros that have enhanced security and anonymity as a feature are not installable on a PC, but that exactly is what’s unique about Whonix. It’s based on Debian but all internet connections go via the Tor network. The latter is called Whonix-Gateway with Whonix-Workstation being what you use to work on your system. It may sound like being overly careful but it has me intrigued.

Entertainment

In many ways, these are appliance distros for anyone who just wants an install-it-and-go approach to things. That works better with dedicated devices than with multipurpose machines, so that is one thing that needs to be kept in mind.

Lakka

The idea behind this offering is what it offers console gamers. Legacy games and peripherals will work and there even is support for Raspberry Pi as well.

LibreELEC

The main purpose of this distro is to offer a home for the KODI entertainment centre on PC and Raspberry Pi devices. It follows from the now defunct OpenELEC project, which ran into trouble when developers’ voices were not given a hearing.

OSMC

The acronym stands for Open-Source Media Centre and there is KODI here too. Though the distro also is based on Debian, one is tempted to wonder why anyone would not just install that and install KODI on top of it. The answer possibly has something got to do with added user-friendliness for those who do not need to deal with such things.

Mandriva Offshoots

Mandrake once was a spin of Red Hat with a more user-friendly focus. In the days before the appearance of Ubuntu, it would have been a choice for those not wanting to overcome obstacles such as a level of hardware support that was much less than what we have today. Later, Mandrake became Mandriva following litigation and the acquisition of Conectiva in 2005. The organisation has declined since those heady days and it became defunct during 2015. Its legacy continues though in the form of two spin-off projects, so all the work of forebears has not been lost.

Mageia

It was the uncertainty surrounding the future of Mandriva that originally caused this project to be started. Beginnings have been promising, so this is a one to watch, though you have to wonder if the now community-based OpenMandriva is stealing some of its limelight.

OpenMandriva

Of the pair that is listed here, it is OpenMandriva which is a continuation of the now-defunct Mandriva. Seeing how things progress for a project with user-friendliness at its heart will be of interest in these days when Debian, Ubuntu and Linux Mint are so pervasive. Even with those, there are KDE options, so there is a challenge in place.

ROSA

Anything Russian may not be everyone’s choice given the state of world affairs at the time of writing, yet this still is an offshoot of Mandriva so it gets a mention in this list. Desktop environment options include KDE, XFCE and LXQt and there are various use cases covered by a range of solutions.

Others

Not every distro falls in the above categories, and some that you find here may surprise you. There are some better-known names like openSUSE that go their way.

EasyOS

Aside from the founder’s dislike of ISO disk images for whatever reason, this distro has its own eccentricities. For example, it is container-friendly, runs in memory as root and much more. This is branded as an experimental distro, and it is that in many ways.

GeckoLinux

This project creates respins of openSUSE for the sake of a more refined experience.  For instance, there are live booting ISO images as well as inclusion of media codecs. There is plenty of choice too when it comes to desktop environments.

Gentoo

From what I have seen, this project seems to be supporting the same needs as Arch, albeit with all software needing to be compiled, so there’s more of a DIY approach. The wiki also comes in handy for those users.

KaOS

Billing itself as a lean independent distribution focussing on QT and KDE, this is built from the ground up without any dependence on other distros. Some tools, like pacman, naturally come from elsewhere in this otherwise standalone offering.

MakuluLinux

Here is another distro apart from Ubuntu that has an African name, the Zulu for big chief this time around. It came to my notice among the pages of the now defunct Micro Mart magazine and uses MATE, XFCE, Enlightenment and KDE as its desktop environment choices.

NuTyX

It is very unusual to see a script that adds the feel of one distro to another, yet that is what you find here. Originally, NuTyX was built using Linux From Scratch but it has matured to the point where you also find ISO installation images to go with the unconventional approach described earlier. Otherwise, the choice of desktop environment includes MATE, LXDE, LXQt, Enlightenment, GNOME, KDE5 and XFCE and the distro has its own package manager called CARDS.

openSUSE

SuSE Linux was one of the first Linux distros that I started to explore and I even had it loaded on my home PC as a secondary operating system for quite a while too before my attention went elsewhere. Only for a PC Plus cover-mounted CD, it never might have discovered it and it bested Red Hat, which was as prominent then, as Fedora is today. When SuSE fell into Novell’s hands, it became both openSUSE and SuSE Linux Enterprise Edition. The former is the community and the latter is what Novell, now itself an Attachmate Group company, offers to business customers. As it happens, I continue to keep an eye on openSUSE and even had it on a secondary PC before font resolution deficiencies had me looking elsewhere. While it’s best known for its KDE variant, there is a GNOME one too and it is this that I have been examining.

PCLinuxOS

There was a time when this was being touted as an Ubuntu killer but it never seems to have made good on that promise. Recent troubles within the project haven’t helped either, especially with a long wait between releases.

Pisi

This Turkish distro recently got reviewed in Linux Format and they were not satisfied with its documentation. It does not help that the website is not in English, so you need a translation tool of your choosing for this one.

Solus

Though there also is a spin using the MATE desktop environment, this distro is perhaps better known as the home for the Budgie desktop environment. All of this is for computing and not its business or enterprise counterpart. There is nothing to say against that and may make it feel a little more friendly.

Tizen

The name sounded similar for some reason and I reckon that’s because Samsung has smartphones running Tizen on sale. The whole point of the project is to power mobile computing platforms with only the mention of netbooks sullying an otherwise non-PC target market that includes tablets and TV’s. It’s overseen by the Linux Foundation too.

Snap Preview… removed

1st February 2007

Snap Preview has been removed from this blog with immediate effect after seeing a blog post by Nick Wilson decrying it from a user perspective. I can accept that it is intrusive but I have to admit that I still find it something of a novelty. However, visitor annoyance easily overrides any appeal that such a widget may hold for me and it has had to go.

Amateur Photographer reviews…

19th July 2007

Amateur Photographer seem to have had a run of reviews recently. First off were the Olympus E-410 and E-510 that they seemed to like. Then, they moved onto the Ricoh Caplio GX100 and they seemed to like that too, though they did say that quality wasn’t up to SLR standards. But then again, it is a compact and that might be expecting a bit too much. This week, Paint Shop Pro comes under the spotlight as does Epson’s V350 scanner. I have yet to read these but I have been engaging in a spot of equipment acquisition anyway. My CanoScan 5000F scanner has been usurped by Epson’s Perfection Photo 4490 and very happy I am with it too. The quality of the scans that I have been doing of prints has been good and the presence of an on/off switch is a creditable one. None of the other scanners that I have had possessed it and having to plug something in and out from the power socket is inconvenient to say the least. I have also gone and got myself a new DSLR. Seeing Pentax’s K10D going with a 18-55 mm lens for £499 at Jessop’s overrode my better reason and put paid to ideas of purchasing any other electronic goods for the rest of this year. It’s an award-winning gadget and Photography Monthly’s Will Cheung seemed to get on fine with it. Which Digital Camera said it was heavy but it has to stand up to use in the great outdoors. The sensor may be a 10 megapixel affair so this will be an upgrade to my Canon EOS 10D; that has a sensor in need of clean right now (I plan to get it done by the professionals) and every time that I want to use an image that it has made, Photoshop’s healing brush has to be pressed into service. Pentax does boast about all of the seals that it has added to the K10D, a good thing if they cut down on the dust entering the camera. And if dust does get in, the sensor cleaning feature will hopefully see it off from the photos. Image stabilisation, another value adding feature, is also there and may prove interesting. Strangely, there’s some motion picture capture as well and I hope that it doesn’t get the EU coming after me to collect retrospective camcorder duty. In any case, it’s not a feature that I really need and the Live View functions on the equivalent Olympus offerings fall into the same category anyway. It’ll be interesting to see how the K10D performs and it’s a change from the Canon/Nikon hegemony that seems to dominate digital photography these days.

Pentax K10D

Update: I have since perused the current issue of Amateur Photographer and seen that Paint Shop Pro suffered from performance issues on computers that worked fine with Photoshop. Otherwise, it compared well with Adobe’s offerings even if the interface wasn’t seen to be as slick. Epson’s V350 was well received though it was apparent that spending more got you a better scanner but that’s always the way with these things.

Dealing with an “Your insider preview build settings need attention” message in Windows 10 Settings

5th September 2016

Fix-Your-Insider-preview-build-settings-need-attention_560

Having now upgraded all my Windows 10 machines to the Anniversary Update edition without much in the way of upheaval, I came across the following message on one of them:

Your insider preview build settings need attention. Go to Windows Insider Programme to fix this.

It appeared on the Update screen of the Settings application and I believe that I may have triggered it by letting foolish curiosity take me to the Windows Insider Programme screen. Returning there offered no way of resolving the issue so I had to try the registry editing tip that I discovered elsewhere on the web. Naturally, the creation of a System Restore Point before proceeding with changes to the Windows Registry is advised.

Typing REGEDIT into Cortana brings up a clickable link to the Registry Editor. Having clicked on this, I then clicked on the Yes button on the ensuing dialogue box that Windows 10 throws up every time you make a system change such as installing new software. With the Registry Editor opened, I made my way to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\UI\Strings

Once there, I deleted every entry that mentioned “Insider” or “Windows Insider” to leave only two afterwards: "(Default)", "UnknownErrorDialogValues". That resolved the issue and I now intend to stay away from the Windows Insider Programme screen in Settings so that the message never appears again.

More thoughts on Windows 10

11th August 2015

Now that I have left Windows 8.x behind me and there are a number of my machines running Windows 10, I have decided to revisit my impressions of the operating system. The first Technical Preview was something that I installed in a virtual machine and I have been keeping an eye on things have developed since then and intend to retain a Windows Insider installation to see what might be heading our way as Windows 10 evolves as now expected.

After elaborating on the all important upgrade process earlier, I am now moving onto other topics. The Start Menu is a big item but there are others as you will see below.

Start Menu

Let’s start with an admission: the prototype Start Menu that we got in the initial Windows 10 Technical Preview was more to my liking. Unpinning all the tiles allowed the menu to collapse back to the sort of width that anyone familiar with Windows 7 would have liked. If there was a setting to expunge all tiles at once and produce this state, I would have been well happy.

It was latter that we got to learn that Microsoft was not about consign the Windows 8 Modern interface entirely to history as many would have wanted. Some elements remain with us such as a Start Menu with a mandatory area for tiles and the ability to have it display full screen. Some are live but this can be turned off on a tile by tile basis and unneeded ones can be removed altogether. It is even possible to uninstall most apps by right clicking on a tile or other Start Menu entry and select the required option from the resulting context menu. For others, there is a command line alternative that uses Powershell to do removals. After this pruning, things were left in such a state that I have not been moved to restore Classic Shell so far.

The Start Menu settings used be in the same place as those for the taskbar but they are found in the new Settings tool. Some are in the Personalisation section and it has its own Start subsection for setting full screen mode or highlighting of new apps among other things. The equivalent Colours subsection is where you find other settings like assigning background colours based on those in a desktop background image, which itself is assigned in it own subsection in the Personalisation area.

Virtual Desktops

Initially, I failed to see the point in how Microsoft implemented these and favoured Virtuawin instead. My main complaint was the taskbar showed buttons for all open apps regardless of the screen in which they are opened. However, that was changed so your taskbar shows different buttons for each virtual desktop, just like the way that Linux and UNIX do things. Switching between desktops may not be as smooth of those yet but the default setting is a move in the right direction and you can change it if you want.

Cortana

This was presented to the world as a voice operated personal assistant like Apple’s Siri but I cannot say that I am keen on such things so I decided to work as I usually do instead. Keyboard interaction works fine and I have neutered things to leave off web searches on Bing to use the thing much in the same way as the search box on the Windows 7 Start Menu. It may be able to do more than that but I am more than happy to keep my workflow unchanged for now. Cortana’s settings are available via its pop-up menu. Collapsing the search box to an icon to save space for your pinned and open applications is available from the Search section of the taskbar context menu (right clicking the taskbar produces this).

Settings

In Windows 8.x, the Control Panel was not the only area for settings but remained feature complete but the same is not the case for Windows 10 where the new Settings panel is starting to take over from it. The two co-exist for now but it seems clear that Settings is where everything is headed.

The Personalisation section of the tool has been mentioned in relation to the Start Menu but there are plenty of others. For instance, the Privacy one is one that definitely needs reviewing and I found myself changing a lot of the default settings in there. Naturally, there are some other sections in Settings that need hardly any attention from most of us and these include Ease of access (accessibility), Time & language, Devices and Network & Internet. The System section has a few settings like tablet mode that may need review and the Update & security one has backup and recovery subsections that may be of interest. The latter of these is where you find the tools for refreshing the state of the system following instability or returning to a previous Windows version (7 or 8.x) within thirty days of the upgrade.
