Summer Computing

20180519_190444.jpg
Working with my Toshiba Chromebook 2, in a sunny day.

I am not sure whether this is true for other countries, but after a long, dark and cold winter, Finns want to be outdoors, when it is finally warm and sunny. Sometimes one might even do remote work outdoors, from a park, cafe or bar terrace, and that is when things can get interesting – with that “nightless night” (the sun shining even at midnight), and all.

Surely, for most aims and purposes, summer is for relaxing and dragging your work and laptop always with you to your summer cottage or beach is not a good idea. This is definitely precious time, and you should spend it to with your family and friends, and rewind from the hurries of work. But, if you would prefer (or, even need to, for a reason or another) take some of your work outdoors, the standard work laptop computer is not usually optimal tool for that.

It is interesting to note, that your standard computer screens even today are optimised for a different style of use, as compared to the screens of today’s mobile devices. While the brightest smartphone screens today – e.g. the excellent OLED screen used in Samsung Galaxy S9 – exceed 1000 nits (units of luminance: candela per square meter; the S9 screen is reported to produce max 1130 nits), your typical laptop computer screens max out around measly 200 nits (see e.g. this Laptop Mag test table: https://www.laptopmag.com/benchmarks/display-brightness ). While this is perfectly good while working in a typical indoor, office environment, it is very hard to make out any details of such screens in bright sunlight. You will just squint, get a headache, and hurt your eyes, in the long run. Also, many typical laptop screens today are highly reflective, glossy glass screens, and the matte surfaces, which help against reflections, have been getting very rare.

It is as the “mobile work” that is one of the key puzzwords and trends today, means in practice only indoor-to-indoor style of mobility, rather than implying development of tools for truly mobile work, that would also make it possible to work from a park bench in a sunny day, or from that classical location: dock, next to your trusty rowing boat?

I have been hunting for business oriented laptops that would also have enough maximum screen brightness to scale up to comfortable levels in brighly lit environments, and there are not really that many. Even if you go for tablet computers, which should be optimised for mobile work, the brightness is not really at level with the best smartphone screens. Some of the best figures come from Samsung Galaxy Tab S3, which is 441 nits, iPad Pro 10.5 inch model is reportedly 600 nits, and Google Pixel C has 509 nits maximum. And a tablet devices – even the best of them – do not really work well for all work tasks.

HP has recently introduced some interesting devices, that go beyond the dim screens that most other manufacturers are happy with. For example, HP ZBook Studio x360 G5 supposedly comes with a 4k, high resolution anti-glare touch display that supports 100 percent Adobe RPG and which has 600 nits of brightness, which is “20 percent brighter than the Apple MacBook Pro 15-inch Retina display and 50 percent brighter than the Dell XPS UltraSharp 4K display”, according to HP. With its 8th generation Xeon processors (pro-equivalent to the hexacore Core i9), this is a powerful, and expensive device, but I am glad someone is showing the way.

Even better, the upcoming, updated HP EliteBook x360 G3 convertible should come with a touchscreen that has maximum brightness of 700 nits. HP is advertising this as the “world’s first outdoor viewable display” for a business laptop, which at least sounds very promising. Note though, that this 700 nits can be achieved with only the 1920 x 1080 resolution model; the 4K touch display option has 500 nits, which is not that bad, either. The EliteBooks I have tested also have excellent keyboards, good quality construction and some productivity oriented enhancements that make them an interesting option for any “truly mobile” worker. One of such enhancement is a 4G/LTE data connectivity option, which is a real bless, if one moves fast, opening and closing the laptop in different environments, so that there is no reliable Wi-Fi connection available all the time.

Apart from the challenges related to reliable data connectivity, a cloud-based file system is something that should be default for any mobile worker. This is related to data security: in mobile work contexts, it is much easier to lose one’s laptop, or get it robbed. Having a fast and reliable (biometric) authentication, encrypted local file system, and instantaneous syncronisation/backup to the cloud, would minimise the risk of critical loss of work, or important data, even if the mobile workstation would drop into a lake, or get lost. In this regard, Google’s Chromebooks are superior, but they typically lack the LTE connectivity, and other similar business essentials, that e.g. the above EliteBook model features. Using a Windows 10 laptop with either full Dropbox synchronisation enabled, or with Microsoft OneDrive as the default save location will come rather close, even if the Google Drive/Docs ecosystem in Chromebooks is the only one that is truly “cloud-native”, in the sense that all applications, settings and everything else also lives in the cloud. Getting back to where you left your work in the Chrome OS means that one just picks up any Chromebook, logs in, and starts with a full access to one’s files, folders, browser addons, bookmarks, etc. Starting to use a new PC is a much less frictionless process (with multiple software installations, add-ons, service account logins, the setup can easily take full working days).

20180519_083722.jpgIf I’d have my ideal, mobile work oriented tool from today’s tech world, I’d pick the business-enhanced hardware of HP EliteBook, with it’s bright display and LTE connectivity, and couple those with a Chrome OS, with it’s reliability and seamless online synchronisation. But I doubt that such a combo can be achieved – or, not yet, at least. Meanwhile, we can try to enjoy the summer, and some summer work, in bit more sheltered, shady locations.

Chilies: May 2017 update

2017-05-21 13.06.31-1
Tepin x Lemon Drop hybrid is the tallest plant at the moment. It has also started to bear fruit, already!

I have been growing a variety of chili peppers for a few years now, and the most of summers 2015 and 2016 were spent building and then testing the Juliana greenhouse that we use for extending the warm season here in Finland. This year however, April was the coldest in record, and there was no point in taking plants outdoors, when it would had just meant having the electric heater working around the clock (which means: expensive chilies!) Now, at the end of May, it finally looks like the unseasonal snow storms could be behind us (knocking on wood…) and this weekend has been the one when the greenhouse has been set up for business, most of the chilies have moved into bigger pots, while there has been also plenty of other work going on in our garden.

As I wrote earlier, I tried out the simple Ikea hydroponic system in germination and sapling phases. The early steps worked very well, and it seems that for indoor chili growing the setup is good for these first steps. However (partially due to the deferred Spring), I kept the saplings too long in the hydroponic setup – if large plants like chilies are grown in hydroponic manner, it needs to have a water pump installed, that keeps the nutritious water flowing over the roots, rather than just soaking them. I did not have the pump, and ended up in troubles, with growth of some plants suffering, and even losing a couple of important chili varieties. I moved the remaining plants into soil and pots in early April, if I remember correctly, but I should had done that much earlier. The growth was strong after the move, even while growing plants had to get along on the windowsill, without any extra plant lights from that onwards.

Scorpion, one from Messukylä school sale.

Luckily, there was the school yard sale in the local Messukylä school, where again hundreds of plants, dozens of chilies included, were available, so I could supplement my selection. I lost all my Aji varieties, and both of my extra hot varieties, “7 pot Brain Strain Yellow” and the Bhut Jolokia. But from the school sale I managed to get both a new Bhut Jolokia, as well as a Moruga Scorpion – both traditionally top of the line, as long as heat is measured. And there were also a couple of interesting habanero varieties that I picked up, as well as something that was called “Jalapeno Hot”. I have only tried rather mild japapenos so far, so it is interesting to see how that will turn out.

Here are some photos from the chilies at this point, 21st May: the school yard saplings are much smaller than the ones that I had grown in hydroponics and then in pots starting in January. The “Naga” (Bhut Jolokia) is particularly small, hopefully it will survive the move into a larger pot, it does not have particularly strong roots yet.

My “Madame Jeannette” habanero is growing strong, though still indoors.

Pequin Firecracker is also making nice growth right now, it should move to the greenhouse in near future, I think.

Talking about roots, I try this time using a specific commercial nutritient, Biobizz “Root Juice”: it is an organic “root stimulator” designed to boost root growth. As I had a gift voucher to a local chili gardeners’ store (thanks, Gamelab colleagues!), I have now also other nutritients to try – sticking to Biobizz products, per shopkeeper’s advice in soil based chili cultivation.

“Root Juice”.

My other tools in testing: “Top-Max”, “Bio-Bloom”, “Bio-Grow” by Biobizz (company is originally from the Netherlands), and also the Finnish classic, “Jaakon taika” (a photosynthesis booster).

Building a greenhouse, pt. 1

Digging in the dirt (photo).
Digging in the dirt.

The building project of this summer has been to make a greenhouse – for my chilli peppers, as well as other vegetables for the family. Construction of proper foundation for a rather sensitive small building that will mostly consist of sheets of glass and thin bars of aluminium is important; however, July was mostly rainy and we also were travelling a lot, so most of the digging was still to be done in early August. Now, in mid-August, the hole in the ground is almost deep enough (in Finland earth can freeze in quite deep during winters, and our garden is on top of several meters of clay, which expands when it freezes; thus – a lot of showel-work). Since our backyard is a bit on the small side, there was a narrow spot where the entire construction had to fit into. But the hole is now there. Have I mentioned that going down into solid clay is somewhat heavy digging?

In other news, our pick for the greenhouse kit manufacturer was Juliana: http://juliana.com/en/products/juliana/

I have also already got the watering system (that I have also already used during our travels for my chillies), from Blumat.

Next steps will probably involve some concrete and a lot of gravel. And a shovel and a wheelbarrow.
