Self hosting Google fonts
14th November 2022One thing that I have been doing across my websites is to move away from using Google web fonts using the advice on the Switching.Software website. While I have looked at free web font directories like 1001 Free Fonts or DaFont, they do not have the full range of bolding and character sets that I desire so I opted instead for the Google Webfonts Helper website. That not only offered copies of what Google has but also created a portion of CSS that I could add to a stylesheet on a website, making things more streamlined. At the same time, I also took the opportunity to change some of the fonts that were being used for sake of added variety. Open Sans is good but there are other acceptable sans-serif options like Mulish or Nunita as well, so these got used.
A desktop Markdown editing environment
8th November 2022Earlier this year, I changed over two websites from dynamic versions using content management systems to static ones by using Hugo to build them from Markdown files. That meant that I needed to look at the editing of MarkDown even if it is a fairly simple file format. For one thing, Grammarly can be incorporated into WordPress so I did not want to lose something like that.
The latter point meant that I was steered away from plain text editors. Otherwise, there are online ones like StackEdit and Dillinger but the Firefox Grammarly plugin only appears to work on the first of these, and even then only partially in my experience. Dillinger does offer connections to online file storage providers like Google, Dropbox and OneDrive but I wanted to store files on my desktop for upload to a web server. It also works with Github but I prefer to use another web hosting provider.
There are various specialised MarkDown editors for desktop usage like Typora, ReText, Formiko or Ghostwriter but I chose none of these. My actual choice may surprise many: it was Visual Studio Code. The availability of a Grammarly plug-in was what swayed it for me even if it did need to be switched on for MarkDown files. In many ways, it does work as smoothly as elsewhere because it gets fooled by links and other code-like pieces of text. Also, having the added ability to add words to a custom dictionary would be ideal. Some rule overriding is available but I am not sure that everything is covered even if the list of options is lengthy. Some time is needed to inspect all of them before I proceed any further. Thus far, things are working well enough for me.
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.
Limiting Google Drive upload & synchronisation speeds using Trickle
9th October 2021Having had a mishap that lost me some photos in the early days of my dalliance with digital photography, I have been far more careful since then and that now applies to other files as well. Doing regular backups is a must that you find reiterated by many different authors and the current computing climate makes doing that more vital than it ever was.
So, as well as having various local backups, I also have remote ones in the form of OneDrive, Dropbox and Google Drive. These more correctly are file synchronisation services but disciplined use can make them useful as additional storage facilities in the interests of maintaining added resilience. There also are dedicated backup services that I have seen reviewed in the likes of PC Pro magazine but I have to make use of those.
Insync
Part of my process for dealing with new digital photo files is to back them up to Google Drive and I did that with a Windows client in the early days but then moved to Insync running on Linux Mint. One drawback to the approach is that this hogs the upload bandwidth of an internet connection that has yet to move to fibre from copper cabling. Having fibre connections to a local cabinet helps but a 100 KiB/s upload speed is easily overwhelmed and digital photo file sizes keep increasing. It does not help that I insist on using more flexible raw formats like DNG, CR2 or CR3 either.
Making fewer images could help to cut the load but I still come away from an excursion with many files because I get so besotted with my surroundings. This means that upload sessions take numerous hours and can extend across calendar days. Ultimately, this makes my internet connection far less usable so I want to throttle upload speed much like what is possible in the Transmission BitTorrent client or in the Dropbox client. Unfortunately, this is not available in Insync so I have tried using the trickle command instead and an example is below:
trickle -d 2000 -u 50 insync
Here, the upload speed is limited to 50 KiB/s while the download speed is limited to 2000 KiB/s. In my case, the latter of these hardly matters while the former leaves me with acceptable internet usability. Insync does not work smoothly with this, however, so occasional restarts are needed to keep file uploads progressing and CPU load also is higher. As rough as the user experience feels, uploads can continue in parallel with other work.
gdrive
One other option that I am exploring is the use of the command-line tool gdrive and this appears to work well with trickle. After downloading and installing the tool, getting going is a matter of issuing the following command and following the instructions:
gdrive about
On web servers, I even have the tool backing up things to Google Drive on a scheduled basis. Because of a Google Drive limitation that I have encountered not only with gdrive but also with Insync and Google’s own Windows Google Drive client, synchronisation only can happen with two new folders, one local and the other remote. Handily, gdrive supports the usual bash style commands for working with remote directories so something like the following will create a directory on Google Drive:
gdrive mkdir ttdc [ID for parent folder]
Here, the ID for the parent folder may be omitted but it can be obtained by going to Google Drive online and getting a link location by right-clicking on a folder and choosing the appropriate context menu item. This gets you something like the following and the required identifier is found between the last slash and the first question mark in the address string (so as not to share any real links, I made the address more general below):
https://drive.google.com/drive/folders/[remote folder ID]?usp=sharing
Then, synchronisation uses a command like the following:
gdrive sync upload [local folder or file path] [remote folder ID]
There also is the option to do a one-way upload and this is the form of the command used:
gdrive upload [local folder or file path] -p [remote folder ID]
Because every file or folder object has its own ID on Google Drive, it is possible to create two objects on there that appear to have the same name though that is sure to cause confusion even if you know what is happening. It is possible in each of the above to throttle them using trickle as well:
trickle -d 2000 -u 50 gdrive sync upload [local folder or file path] [remote folder ID]
trickle -d 2000 -u 50 gdrive upload [local folder or file path] -p [remote folder ID]
Handily, this works without the added drama seen with Insync and lends itself to scripting as well so it could be something that I will incorporate into my current workflow. One thing that needs to be watched is file upload failures but there may be ways to catch those and retry them so that would another thing that needs doing. This is built into Insync and it would be a learning opportunity if I was to stick with gdrive instead.
Some books and other forms of documentation on R
11th September 2021The thrust of an exhortation from a computing handbook publisher comes to mind here: don’t just look things up on Google, read a book so you really understand what you are doing. Something like those words was used to sell an eBook on Github but the same sentiment applies to R or any other computing language. Using a search engine will get you going or add to existing knowledge but only a book or a training course will help to embed real competence.
In the case of R, there is a myriad of blogs out there that can be consulted as well as function and package documentation on RDocumentation or rrdr.io. For the former, R-bloggers or R Weekly can make good places to start while ones like Stats and R, Statistics Globe, STHDA, PSI’s VIS-SIG and anything from Posit (including their main blog as well as their AI one) can be worth consulting. Additionally, there is also RStudio Education and the NHS-R Community, which also have a Github repository together with a YouTube channel. Many packages have dedicated websites as well so there is no lack of documentation with all of these so here is a selection:
To come to the real subject of this post, R is unusual in that books that you can buy also have companions websites that contain the same content with the same structure. Whatever funds this approach (and some appear to be supported by RStudio itself by the looks of things), there certainly are a lot of books available freely online in HTML as you will see from the list below while a few do not have a print counterpart as far as I know:
R Programming for Data Science
R Markdown: The Definitive Guide
bookdown: Authoring Books and Technical Documents with R Markdown
blogdown: Creating Websites with R Markdown
pagedown: Create Paged HTML Documents for Printing from R Markdown
Dynamic Documents with R and knitr
Engineering Production-Grade Shiny Apps
Outstanding User Interfaces with Shiny
Happy Git and GitHub for the useR
Outstanding User Interfaces with Shiny
Engineering Production-Grade Shiny Apps
Many of the above have counterparts published by O’Reilly or Chapman & Hall, to name the two publishers that I have found so far. Aside from sharing these with you, there is also the personal motivation of having the collection of links somewhere so I can close tabs in my Firefox session. There are other web articles open in other tabs that I need to retain and share but these will need to do for now and I hope that you find them as useful as I do.
Moving a website from shared hosting to a virtual private server
24th November 2018This year has seen some optimisation being applied to my web presences guided by the results of GTMetrix scans. It was then that I realised how slow things were, so server loads were reduced. Anything that slowed response times, such as WordPress plugins, got removed. Usage of Matomo also was curtailed in favour of Google Analytics while HTML, CSS and JS minification followed. What had yet to happen was a search for a faster server. Now, another website has been moved onto a virtual private server (VPS) to see how that would go.
Speed was not the only consideration since security was a factor too. After all, a VPS is more locked away from other users than a folder on a shared server. There also is the added sense of control, so Let’s Encrypt SSL certificates can be added using the Electronic Frontier Foundation’s Certbot. That avoids the expense of using an SSL certificate provided through my shared hosting provider and a successful transition for my travel website may mean that this one undergoes the same move.
For the VPS, I chose Ubuntu 18.04 as its operating system and it came with the LAMP stack already in place. Have offload development websites, the mix of Apache, MySQL and PHP is more familiar to me than anything using Nginx or Python. It also means that .htaccess files become more useful than they were on my previous Nginx-based platform. Having full access to the operating system by means of SSH helps too and should mean that I have fewer calls on technical support since I can do more for myself. Any extra tinkering should not affect others either, since this type of setup is well known to me and having an offline counterpart means that anything riskier is tried there beforehand.
Naturally, there were niggles to overcome with the move. The first to fix was to make the MySQL instance accept calls from outside the server so that I could migrate data there from elsewhere and I even got my shared hosting setup to start using the new database to see what performance boost it might give. To make all this happen, I first found the location of the relevant my.cnf configuration file using the following command:
find / -name my.cnf
Once I had the right file, I commented out the following line that it contained and restarted the database service afterwards using another command to stop the appearance of any error 111 messages:
bind-address 127.0.0.1
service mysql restart
After that, things worked as required and I moved onto another matter: uploading the requisite files. That meant installing an FTP server so I chose proftpd since I knew that well from previous tinkering. Once that was in place, file transfer commenced.
When that was done, I could do some testing to see if I had an active web server that loaded the website. Along the way, I also instated some Apache modules like mod-rewrite using the a2enmod command, restarting Apache each time I enabled another module.
Then, I discovered that Textpattern needed php-7.2-xml installed, so the following command was executed to do this:
apt install php7.2-xml
Then, the following line was uncommented in the correct php.ini configuration file that I found using the same method as that described already for the my.cnf configuration and that was followed by yet another Apache restart:
extension=php_xmlrpc.dll
Addressing the above issues yielded enough success for me to change the IP address in my Cloudflare dashboard so it pointed at the VPS and not the shared server. The changeover happened seamlessly without having to await DNS updates as once would have been the case. It had the added advantage of making both WordPress and Textpattern work fully.
With everything working to my satisfaction, I then followed the instructions on Certbot to set up my new Let’s Encrypt SSL certificate. Aside from a tweak to a configuration file and another Apache restart, the process was more automated than I had expected so I was ready to embark on some fine-tuning to embed the new security arrangements. That meant updating .htaccess files and Textpattern has its own, so the following addition was needed there:
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
This complemented what was already in the main .htaccess file and WordPress allows you to include http(s) in the address it uses, so that was another task completed. The general .htaccess only needed the following lines to be added:
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.assortedexplorations.com/$1 [R,L]
What all these achieve is to redirect insecure connections to secure ones for every visitor to the website. After that, internal hyperlinks without https needed updating along with any forms so that a padlock sign could be shown for all pages.
With the main work completed, it was time to sort out a lingering niggle regarding the appearance of an FTP login page every time a WordPress installation or update was requested. The main solution was to make the web server account the owner of the files and directories, but the following line was added to wp-config.php as part of the fix even if it probably is not necessary:
define('FS_METHOD', 'direct');
There also was the non-operation of WP Cron and that was addressed using WP-CLI and a script from Bjorn Johansen. To make double sure of its effectiveness, the following was added to wp-config.php to turn off the usual WP-Cron behaviour:
define('DISABLE_WP_CRON', true);
Intriguingly, WP-CLI offers a long list of possible commands that are worth investigating. A few have been examined but more await attention.
Before those, I still need to get my new VPS to send emails. So far, sendmail has been installed, the hostname changed from localhost and the server restarted. More investigations are needed but what I have not is faster than what was there before, so the effort has been rewarded already.
Rethinking photo editing
17th April 2018Photo editing has been something that I have been doing since my first-ever photo scan in 1998 (I believe it was in June of that year but cannot be completely sure nearly twenty years later). Since then, I have been using a variety of tools for the job and wondered how other photos can look better than my own. What cannot be excluded is my preference for being active in the middle of the day when light is at its bluest as well as a penchant for using a higher ISO of 400. In other words, what I do when making photos affects how they look afterwards as much as the weather that I had encountered.
My reason for mentioning the above aspects of photographic craft is that they affect what you can do in photo editing afterwards, even with the benefits of technological advancement. My tastes have changed over time, so the appeal of re-editing old photos fades when you realise that you only are going around in circles and there always are new ones to share, so that may be a better way to improve.
When I started, I was a user of Paint Shop Pro but have gone over to Adobe since then. First, it was Photoshop Elements, but an offer in 2011 lured me into having Lightroom and the full version of Photoshop. Nowadays, I am a Creative Cloud photography plan subscriber so I get to see new developments much sooner than once was the case.
Even though I have had Lightroom for all that time, I never really made full use of it and preferred a Photoshop-based workflow. Lightroom was used to select photos for Photoshop editing, mainly using adjustments for such things as tones, exposure, levels, hue and saturation. Removal of dust spots, resizing and sharpening were other parts of a still minimalist approach.
What changed all this was a day spent pottering about the 2018 Photography Show at the Birmingham NEC during a cold snap in March. That was followed by my checking out the Adobe YouTube Channel afterwards where there were videos of the talks featured every day of the four-day event. Here are some shortcuts if you want to do some catching up yourself: Day 1, Day 2, Day 3, and Day 4. Be warned though that these videos are long in that they feature the whole day and there are enough gaps that you may wish to fast-forward through them. Even so, there is quite a bit of variety of things to see.
Of particular interest were the talks given by the landscape photographer David Noton who sensibly has a philosophy of doing as little to his images as possible. It helps that his starting points are so good that adjusting black and white points with a little tonal adjustment does most of what he needs. Vibrancy, clarity and sharpening adjustments are kept to a minimum while some work with graduated filters evens out exposure differences between skies and landscapes. It helps that all this can be done in Lightroom, so that set me thinking about trying it out for size and the trick of using the backslash (\) key to switch between raw and processed views is a bonus granted by non-destructive editing. Others may have demonstrated the creation of composite imagery, but simplicity is more like my way of working.
Confusingly, we now have the cloud-based Lightroom CC while the previous desktop counterpart is known as Lightroom Classic CC. Though the former may allow for easy dust spot removal among other things, it is the latter that I prefer because the idea of wholesale image library upload does not appeal to me for now and I already have other places for off-site image backup like Google Drive and Dropbox. The mobile app does look interesting since it allows capturing images on a such a device in Adobe’s raw image format DNG. Still, my workflow is set to be more Lightroom-based than it once was and I quite fancy what new technology offers, especially since Adobe is progressing its Sensai artificial intelligence engine. The fact that it has access to many images on its systems due to Lightroom CC and its own stock library (Adobe Stock, formerly Fotolia) must mean that it has plenty of data for training this AI engine.
A look at Google’s Pixel C
26th December 2016Since my last thoughts on trips away without a laptop, I have come by Google’s Pixel C. It is a 10″ tablet so it may not raise hackles on an aircraft like the 12.9″ screen of the large Apple iPad Pro might. The one that I have tried comes with 64 GB of storage space and its companion keyboard cover (there is a folio version). Together, they can be bought for £448, a saving of £150 on the full price.
The Pixel C keyboard cover uses strong magnets to hold the tablet onto it and that does mean some extra effort when changing between the various modes. These include covering the tablet screen as well as piggy backing onto it with the screen side showing or attached in such a way that allows typing. The latter usefully allows you to vary the screen angle as you see fit instead of having to stick with whatever is selected for you by a manufacturer. Unlike the physical connection offered by an iPad Pro, Bluetooth is the means offered by the Pixel C and it works just as well from my experiences so far. Because of the smaller size, it feels a little cramped in comparison with a full size keyboard or even that with a 12.9″ iPad Pro. They also are of the scrabble variety though they work well otherwise.
The tablet itself is impressively fast compared to a HTC One A9 phone or even a Google Nexus 9 and that became very clear when it came to installing or updating apps. The speed is just as well since an upgrade to Android 7 (Nougat) was needed on the one that I tried. You can turn on adaptive brightness too, which is a bonus. Audio quality is nowhere near as good as a 12.9″ iPad Pro but that of the screen easily is good enough for assessing photos stored on a WD My Passport Wireless portable hard drive using the WD My Cloud app.
All in all, it may offer that bit more flexibility for overseas trips compared to the bigger iPad Pro so I am tempted to bring one with me instead. The possibility of seeing newly captured photos in slideshow mode is a big selling point since it does functions well for tasks like writing emails or blog posts, like this one since it started life on there. Otherwise, this is a well made device.
More thinking on travelling without a laptop
10th December 2016When it comes to the technology that I carry with me on trips away, I have begun to start weighing devices on my kitchen scales. The results are a little revealing. The HP Pavilion dm5 that has gone with me to Ireland and other places weighs between 2.5 and 3 kg while my Apple iPad Mini 2 comes in at 764 grams. My 12.9″ iPad Pro with its Logitech keyboard weighs between these at 110 to 1200 grams. The idea of consolidating computing devices for travel has been discussed on here before now and the main thing stopping my just going with the iPad Pro was the viewing of photos without filling up its 32 GB of storage space.
Since then, I just may have found a workaround and it is another gadget, this time weighing only a few hundred grams: a 1 TB WD My Passport Wireless portable hard drive. Aside from having a SD card slot that allows the automatic backup of photos, it also can connect with tablets and phones using WiFi broadband.
It is the WD My Cloud app that makes the connections to mobile devices useful and it works smoothly on iOS and Android devices too. Nevertheless, there is more functionality on the latter ones such as DNG file support and an added slide show feature that works with JPEG files. Both of these are invaluable for viewing photos and I feel a little short-changed that they are not available on iOS. Hopefully, that will get resolved sooner rather than later.
Thankfully, my Pentax K5 II DSLR camera can be persuaded to save DNG and JPEG files simultaneously so that they can be viewed full screen on both types of devices without having to transfer them onto the tablet first as you would with Apple’s SD card reader. Usefully, that gets around my oversight in buying iPads with only 32 GB of storage each. That now looks like a false economy given what I am trying now.
Such is the weight difference, just taking along my Apple iPad Pro and the WD device will save around 1 kg and there is less fuss at airport security screening too. While my HTC phone would suffice for seeing photos as slide shows, I am wondering if my battered Google Nexus 9 could come too. The only dilemma then would be how to pack things since I am not sure how a large iPad screen would seem to cabin crew or other passengers during take off and landing. That makes using the Nexus 9 onboard more of a proposition and the iPad might go into the hold luggage to make life a little easier. Still, that choice is a minor concern now that I can try travelling overseas without a laptop to see how I get along.
Pondering travel device consolidation using an Apple iPad Pro 12.9″
18th September 2016It was a change of job in 2010 that got me interested in using devices with internet connectivity on the go. Until then, the attraction of smartphones had not been strong, but I got myself a Blackberry on a pay as you go contract, but the entry device was painfully slow, and the connectivity was 2G. It was a very sluggish start.
It was supplemented by an Asus Eee PC that I connected to the internet using broadband dongles and a Wi-Fi hub. This cumbersome arrangement did not work well on short journeys and the variability of mobile network reception even meant that longer journeys were not all that successful either. Usage in hotels and guest houses though went better and that has meant that the miniature laptop came with me on many a journey.
In time, I moved away from broadband dongles to using smartphones as Wi-Fi hubs and that largely is how I work with laptops and tablets away from home unless there is hotel Wi-Fi available. Even trips overseas have seen me operate in much the same manner.
One feature is that we seem to carry quite a number of different gadgets with us at a time and that can cause inconvenience when going through airport security since they want to screen each device separately. When you are carrying a laptop, a tablet, a phone and a camera, it does take time to organise yourself and you can meet impatient staff, as I found recently when returning from Oslo. Checking in whatever you can as hold luggage helps to get around at least some of the nuisance and it might be time for the use of better machinery to cut down on having to screen everything separately.
When you come away after an embarrassing episode as I once did, the attractions of consolidating devices start to become plain. In fact, most probably could get with having just their phone. It is when you take activities like photography more seriously that the gadget count increases. After all, the main reason a laptop comes on trips beyond Britain and Ireland at all is to back up photos from my camera in case an SD card fails.
Parking that thought for a while, let’s go back to March this year when temptation overcame what should have been a period of personal restraint. The result was that a 32 GB 12.9″ Apple iPad Pro came into my possession along with an Apple Pencil and a Logitech CREATE Backlit Keyboard Case. It should have done so, but the size of the screen did not strike me until I got it home from the Apple Store. That was one of the main attractions because maps can be shown with a greater field of view in a variety of apps, a big selling point for a hiker with a liking for maps, who wants more than what is on offer from Apple, Google or even Bing. The precision of the Pencil is another boon that makes surfing the website so much easier and the solid connection between the case and the iPad means that keyboard usage is less fiddly than it would if it used Bluetooth. Having tried them with the BBC iPlayer app, I can confirm that the sound from the speakers is better than any other mobile device that I have used.
Already, it has come with me on trips around England and Scotland. These weekend trips saw me leave the Asus Eee PC stay at home when it normally might have come with me and taking just a single device along with a camera or two had its uses too. The screen is large for reading on a train but I find that it works just as well so long as you have enough space. Otherwise, combining use of a suite of apps with recourse to the web does much of the information seeking needed while on a trip away and I was not found wanting. Battery life is good too, which helps.
Those trips allowed for a little light hotel room blog post editing too and the iPad Pro did what was needed, though the ergonomics of reaching for the screen with the Pencil meant that my arm was held aloft more than was ideal. Another thing that raised questions in my mind is the appearance of word suggestions at the bottom of the screen as if this were a mobile phone since I wondered if these were more of a hindrance than a help given that I just fancied typing and not pointing at the screen to complete words. Copying and pasting works too but I have found the screen-based version a little clunky so I must see if the keyboard one works just as well, though the keyboard set up is typical of a Mac so that affects word selection. You need to use the OPTION key in the keyboard shortcut that you use for this and not COMMAND or CONTROL as you might do on a PC.
Even with these eccentricities, I was left wondering if it had any utility when it came to backing up photos from digital cameras and there is an SD card adapter that makes this possible. A failure of foresight on my part meant that the 32 GB capacity now is an obvious limitation but I think I might have hit on a possible solution that does not need to upload to an iCloud account. It involves clearing off the photos onto a 128 GB Transcend JetDrive Go 300 so they do not clog up the iPad Pro’s storage. That the device has both Lightning and USB connectivity means that you can plug it into a laptop or desktop PC afterwards too. If that were to work as I would hope, then the laptop/tablet combination that I have been using for all overseas trips could be replaced to allow a weight reduction as well as cutting the hassle at airport security.
Trips to Ireland still may see my sticking with a tried and tested combination though because I often have needed to do some printing while over there. While I have been able to print a test document from an iPad Mini on my home network-connected printer, not every model supports this and that for NFC or Air Print is not universal either. If this were not an obstacle, apps like Pages, Numbers and Keynote could have their uses for business-related work and there are web-based offerings from Google, Microsoft and others too.
In conclusion, I have found that my iPad Pro does so much of what I need on a trip away that retiring the laptop/tablet combination for most of these is not as outrageous as it once would have seemed. In some ways, iOS has a way to go yet before it could take over from macOS but it remains in development so it will be interesting to see what happens next. All the while, hybrid devices running Windows 10 are becoming more pervasive and that might provide Apple with the encouragement that it needs.
