Tech for studying (2): Digitizing notes

There are studies that indicate traditional pen and paper note taking is better for knowledge retention and understanding. To back-up handwritten notes, it is a good idea to digitize them and there are different notebooks designed for this purpose.

Moleskine and Leuchtturm both sell notebooks optimised for digitisation. Moleskine collaborated with Evernote to produce a 'smart' notebook. The notebook's paper has dotted lines that are optimised for scanning via a smartphone/tablet camera. After scanning, content is enhanced for OCR to enable searching handwritten notes in Evernote. The notebook also includes stickers that can be pre-set, within Evernote, to tag scanned documents or to send notes to certain notebooks.

Leuchtturm utilises Whitelines paper that is designed to work with the Whitelines Android/iOS application. Similar to Moleskine's 'smart' notebook, Whitelines paper makes lines disappear and notes standout after scanning. The lines, in this case, are white and the background grey, with four corner markers that auto-detect the page selected for scanning. At the bottom of the page, there are three squares that can be ticked to send the document to an email, Evernote and Dropbox. In the app, it is possible to set destination preferences for each of these options.

I prefer Whitelines paper to Moleskine's Evernote notebook, as the latter is tightly integrated to work within the Evernote app; Whitelines, in contrast, is platform neutral. The results of scanning can vary but Whitelines, from experience, consistently produces better results. Further, it is not necessary to purchase a Leuchtturm notebook to use Whitelines paper, as Whitelines produce their own notebooks that can be purchased in different formats and sizes.

Rocketbook notebooks perform a similar function to the Evernote smart notebook and Leuchtturm’s Whitelines Link notebooks. The difference is that Rocketbook sells re-usable notebooks. The Rocketbook Wave can be erased using microwave heat and re-used up to five times. The Rocketbook Everlast is marketed as “endlessly reusable”; the notebook's pages can be wiped clean using a damp cloth. The Pilot FriXion pen is required to re-use both notebooks. To test Rocketbook’s scannable paper there are PDF downloads here; to get the best result, the sheets should be used with the Rocketbook app.

A final point: handwritten notes, in a regular notebook, can be uploaded to the cloud with a designated scanning app and some of these apps support OCR too. The paper, in these notebooks, may not be optimised for digitization but often, from experience, I found the difference in results negligible (one issue to consider is that lines, in lined notebooks, remain after scanning a document). I regularly use Adobe Scan but there are other applications.

Best budget Chromebooks of 2017

In the previous post on the best budget tech of 2017, I forgot to include Chromebook recommendations. Recently I have moved on from Chromebooks, as I find writing in a browser using Google Docs frustrating and often slow when rendering large documents. There is the option to use Microsoft Word's Android app but the version does not compare to the full desktop version. Further, Google Play is still in Beta on most Chromebooks and Microsoft Word can be unstable and cumbersome to work with a non-touch screen. Despite my problems with Chromebooks recently, I still think the platform meets the needs of many users and is genuinely useful in education.

The budget Chromebooks that stood out in 2017, in my opinion, would be Acer's CB3-431 14" Full HD Chromebook and the Asus C301 13.3. Both devices come with a full HD screen, quad core N3160 processor, 4GB RAM and 32 GB storage (Asus offer the C301 with different processors but the N3160 seems to be the only option that is readily available). I have used the Acer Chromebook 14 and liked the full HD IPS screen. One issue with the laptop is the below average battery life, in comparison to other Chromebooks. I haven't tested the Asus C301 but based on specifications and this review by Chrome Unboxed, it is an affordable Chromebook that gets it right.

Finally, the 32GB storage on both devices means installing Gallium OS is workable (Gallium OS is a Linux distribution that is based on Xubuntu. The distribution is optimised to work with Chromebook hardware). With Gallium OS you get a full fledged desktop environment and can use desktop applications e.g. Libre Office, Firefox, Calibre etc.

Best budget tech of 2017

In late 2016, a number of vendors released entry laptops with 4GB rather than 2GB RAM. For example, we had the HP Stream 14 and the Acer ES11/ES13. Yet, these devices remained restricted due to their underpowered processors. For this reason, I found the Lenovo 110S with its more powerful quad core N3160 a better proposition in comparison to slower dual core N3350/N3060 laptops with 4GB RAM. The device serves the purpose of a secondary mobile laptop and comes with a one-year office 365 subscription. Lenovo recently updated the 110S with the 120S. The latter device, in its base configuration, comes with a weaker dual core Intel Celeron N3350 Processor, making the previous generation the better option. While technically released late 2016, I think the Ideapad 110S is the best entry-level laptop in 2017.

Beyond the entry-level but within the budget category, we have seen the release of a number of laptops with full HD screens, more powerful quad core processors, 4GB RAM and 64GB storage. The 14 inch Asus Vivobook L403 and the Acer Swift 1 13 are examples and both are capable primary laptops. Smaller vendors released similar laptops at lower prices but these devices need to be imported from China, leading to possible complications with after-sale support (on the plus side, I have noticed Geekbuying.com are now shipping laptops from warehouses based in Germany). Based on positive reviews, the Chuwi Lapbook 14.1 and Jumper EZBOOK 3 PRO are the pick of the bunch.

Tablets

Amazon owns the budget tablet category. Cutting the right corners, Amazon delivered stand out tablets in the Fire HD 8 and Fire HD 10. The Fire HD 8 is a solid device, with very good battery life, that delivers what most users expect from a tablet. The Fire HD 10 surpasses expectations with a screen that compares with mid-level tablets. Beyond Amazon, Lenovo released the Tab 4 HD 8; the device is priced higher than Fire HD 8 but comes with a better screen, better cameras and more RAM.

Concerning e-readers, Barnes & Noble released the Nook Glowlight 3 but the device is only available in the US. It will be interesting to see what Amazon do with the Kindle Paperwhite in 2018. I expect Amazon to release a 6 inch Kindle Paperwhite 4 with incremental updates.

Happy new year to all!

To all visitors, I wish you a happy and fruitful new year. I hope that, after some stagnation, 2018 will bring innovative e-readers in all shapes and sizes!

Kindle Oasis 2 accessories

If you wish to use a case for the Kindle Oasis then a third party cover/sleeve is necessary since Amazon withdrew their official version. So far, options are limited. Below is a short list of alternative accessories:
  • Moko specialize in Kindle e-reader and Fire tablet accessories. The Moko case does cover the Oasis completely, unlike the official Amazon case, but does not provide a flat reading surface when open. The case is not perfect and the quality does not compare to Amazon's official covers but, so far, it is the best option. I use the 'Almond Blossoms' Moko case and the painting's print quality is good. Another issue is the cover's weak magnets; when closed the front cover can move. 
  • If you do not mind holding the Oasis bare then a sleeve is a good option to cover the device when travelling. The Amazon Basics eight-inch sleeve, not technically a third party accessory, fits the Oasis perfectly and provides adequate padding. The eight-inch sleeve also fits the Oasis with a case on. 
  • Fintie is another manufacturer that produces Kindle cases. I haven’t tested the cover and so can’t judge its quality. One issue that put me off is the cover’s padded vinyl feel. 
A final point: I would avoid any case with straps, even if advertised compatible with the Oasis. The main issue is the design of the Oasis with one end being thicker. At the thinner end, the straps cover the bottom corners of the screen.

CLEARink's display technology

The advent of the consumer e-reader, introduced by Sony and Amazon (2006 – 2007), contributed to the growth of innovative low-power reflective displays that supported colour. For example, we had different e-paper applications from Fujitsu, Plastic Logic, Mirasol and Liquavista (acquired by Amazon). At first, these e-paper solutions were promising but, so far, nothing materialised

CLEARink is another e-paper solution that promises not only static colour solutions but also video support. The initial focus, according to CLEARink, is to produce devices targeted at education and this means support for both text and video output. If CLEARink delivers on its promise we might even see low-powered laptops fitted with a CLEARink display, making them ideal for out-door reading/writing and with positive eyesight health implications too. This idea is not new, 'One Laptop per Child Foundation' previously partnered with Pixel Xi to produce dual-mode display laptops (Pixel Xi no longer operates). Pixel Xi's dual-mode display, different to CLEARink's technology, allowed the screen's backlight to be turned on and off; the idea was to preserve energy and support outdoor readability.

Oasis PDF support correction

In a previous post regarding the Oasis's PDF support, I stated the following:
I found it useful that the Oasis’s buttons only turn to the next page of a PDF document, rather than scroll down a page; this is a good implementation as it removes any confusion between page scrolling and page turning.
I mainly read PDF files in landscape mode, due to the restricted seven inch screen estate, and, consequently, didn't notice the mistake made in the above observation (also, recently, I've predominately been reading e-books). To clarify, tap to scroll or using the buttons perform the exact same function in a zoomed-in PDF document: i.e., both enable the user to scroll down a page and turn to the next one when a page is completed. Unfortunately, the implementation of this function is buggy and the device, sometimes, for no reason, zooms-in further. In addition, when scrolling to the next page, the Oasis does not jump to the top of the page. As a result, depending on the PDF file, some lines could be accidentally missed. To ensure a page-turn starts at the top of a page it then becomes necessary to drag manually upwards.

To resolve these issues with tap/button-click to scroll, the best option, in my view, is to scroll a page by dragging downwards when zoomed-in. After completing a page, again to avoid the tap to scroll function, first zoom-out with a double tap and then follow this by a tap/button-click to turn the page. In the next page, repeat the double-tap to zoom-in and drag to scroll downwards. This option might be cumbersome but it is workable and makes PDF portrait reading more stable.
