When we started our tour three month ago, I replaced my trusty Lenovo Thinkpad T520 with a shiny new Dell XPS 13 (9360). The reasons where many fold: As weight and volume are premium while travelling half the weight and less than half the volume is awesome. As I didn’t intended to do a lot computer stuff, I settled for a 13 inch screen instead of a 15 inch screen. The other main reason is definitely the battery life. 10 hour of light work or browsing is easily accessible. My previous laptop seldom stayed alive longer than three hours, even with the bigger battery pack.
Obviously I had to make sacrifices somewhere: I already mentioned the smaller screen. Also, I traded power with battery life. Before I had a Intel i7 Quadcore. Now it’s “only” a dual core (although a faster one). I also had to omit a dedicated graphic unit which I had before. But my main drawback is the missing trackpoint. I know people either love or hate them and I loved it.
Out of the different configuration I had chosen the 8Gb, Core i5, Full-HD No-Touch display with 256Gb disk and Ubuntu pre-installed. Because I did not know if I would use this laptop after our travelling as much as while we were travelling, I tried to keep the costs as low as possible. Although I knew I would install Windows, I used the Ubuntu installation a while. A quite nice experience I have to admit.
Nonetheless I installed Windows. After some start problems (the WiFi card was not supported from scratch by windows, so I couldn’t download other drivers…) I installed Windows 10. I also installed “Dell Update” for up-to-date drivers.
(Not really a) review
I would love to do a review of my machine, but I do not use it enough to call it a real “review”. I use it for to keep track of my balance, booking of tours and for some light gaming. Also the occasional programming task when ever an idea struck me. Nonetheless can I say that I am (was) very happy with the laptop. The battery life is fantastic. The display is crisp and the fan spins up only while gaming (or Windows Update running wild…). The bezel of the display is slim and gives the laptop a very good size to display ratio. smaller drawbacks are the missing “roll” button (which I never use, but was activated on Windows by default; Use on screen keyboard to toggle it) and the Fat-Chin-Camera (The camera is located in the lower part of the bezel).
So all in all: A good laptop and I’m looking forward to give Ubuntu another try when I’m back 🙂

(Fiji Is Just) ImageJ 2.0.0-rc-49/1.51c; Java 1.8.0_66 [64-bit]; Windows 10 10.0; 476MB of 9115MB (5%)
java.lang.IllegalArgumentException: adding a container to a container on a different GraphicsDevice
Workaround / Fix:
If you happen to have this bug make sure all instances of ImageJ / Fiji windows are on the same monitor. This bug only occured to me when my Fiji toolbar window was on my main monitor and the plugin windows (Image Sequence loader and Linear Stack Allignment with SIFT) were on my secondary screen.
If you want to reproduce this issue, use a system with the above mentioned spec (see stacktrace).
- Open Fiji on the main display
- Use “File / Import / Image Sequence…” to load at least two images
- Execute “Plugin / Registration / Linear Stack Allignment with SIFT” on the images
- When the registration is performed, move all Fiji windows but the Fiji toolbar to a second display
- Close all the Fiji windows but keep the Fiji toolbar open
- Repeat step 2) and 3)
- Exception gets thrown
This will be the last article in this category, as the course nears its end. I will have a short recap on my experience in this course and how it changed my learning behavior. This is the logical follow up to my post Learning Environment: Status Quo.
Experience in this course
This course differs from all my other courses because this is the first course I took outside my “normal” curriculum. So all fellow students had a different background than me, probably already knew the professor etc.
Yet the course was one of the best I had in University. I think I learned a lot in this course and had contact and insight to many topics which I probably would never had deemed worth investigating. Although the professor is strict and the workload is not deniable, I am happy I chose this course.
In the mentioned article I listed five methods I use when learning:
- Information consumption
- Information curation
1 – Information consumption
I still rely heavily on my ability to consume and process an huge amount of information. So no changes here.
2 – Training
As I mentioned in the linked post, doing is better than listening. In the time of the course I hadn’t had that much training (of any kind, not even my martial art). So I hesitate to write something about this part. The only thing I can think of is the third learning unit (the MOOC), where I had a lot of hands on work to do (see my result here: Instagram)
3 – Discussion
As in the section before, not that much changed here: I went to some meetups and also had good high quality discussions with colleagues. But nothing drastically differed by participating the course.
4 – Information curation
Not that much changed here as well: Only 26 upvotes on good questions or answers on Stackoverflow.com for example.
5 – Reflection
Of the five sections, the “Reflection” section is the one with the most changes, I would think. I wrote 17 posts for this course alone, that’s more than for all other topics in that time span. It feels good to recapitulate the learned topics and to put whole sentences on the blog.
The tools section changed as well. For example I reduced my amount of Feedly and Facebook to 30 minutes a day (StayFocusd for Chrome). The other mentioned tools didn’t change that much. I blogged a little bit more than usual (which is good) and used Stackoverflow and Evernote a bit less.
Something I did add to my toolbox (based on this course) is Pluralsight, a very good training site. I really recommend is warmly. Something I also use since the course is DuoLingo, mostly on my mobile phone. Currently I learn Swedish with DuoLingo and binge watch every thing actor model related on Plurasight.
This blog post is one part of the series “learning diary” for a course at my university.
Goal of this report is to take and rate a online learning unit. For the fourth and final learning unit we should take a mobile learning unit. I used the app Learning Japanese (Google Play Store) for my mobile phone. As an experiment we have been asked to create a video for the review: https://youtu.be/LUS9Tu6RVpo
Short synopsis of the unit:
Learning Japanese is a language learning software for the Android platform. It consists of three main components: The Kana learning (Kana being the two basic alphabets of the Japanese language), an expression trainer (Dates, Time and numbers) as well as a vocabulary trainer.
The app focuses on Kana learning, as all other components build on the ability to read Kana. Based on that skill the “daily expression” tab provides lists of numbers, dates and times as well as tests for these sections. Somewhat easy to overlook is a small icon on the top right corner of the numbers section on which you can enter numbers, which get translated to the corresponding sign (including a sound file).
The third section is reserved for the vocabulary list of the Japanese-Language-Proficiency Test (JLPT). This test is similar to TOEFL or IELTS but for the Japanese language. The needed vocabulary for the five level of this test is listed in this app and can be trained and tested.
Reflection on your personal learning experience
All in all, I’m disappointed. I started (and stopped…) to learn Japanese several years ago and hoped this app could maybe reinforce my small knowledge of the language. Even better I hoped it could ignite my desire to finally learn the language again.
Unfortunately, it didn’t ignite anything. The app may be suited to learners of Japanese which had a more recent encounter with the language but it is in my opinion not helpful for beginners or people looking to refresh their knowledge.
My learning experience with this as (again, basically as a beginner) was frustrating. There is no learning concept at all, just different components like the syllables to memorize.
Did you achieve the stated learning goals?
No, I did not achieve the stated learning goal. As stated before my learning experience was not as good as expected. I think I’m not the right target audience for this app. Maybe with a hint at the description page of the app I would have chosen another app.
Did the given time suffice?
There is not statement how long it does take to memorize all Kana or the provided vocabulary and expressions. Taking the 90 minutes in considerations the mobile learning units should take, I would say that the time is not sufficient.
Even if the learner had some training in the past, the 90 minutes aren’t enough to memorize even one of the Kana (not to speak of the vocabulary and the expressions). I managed to remember the first set of Hiragana (the first of the Kana) after roughly four hours of use, with mediocre results on the tests.
Comment on the design – what was good, what could be made better?
Two main points regarding the design are worth mentioning, when discussing this app: Usability and the used learning method.
Starting with the usability I need to add that I’m not a user interface designer or an expert on this topic. Yet, in my opinion the app lacks usability at certain points:
- No introduction. It would be nice to have a brief introduction in the app. “What is the intended order of the lessons?”, “What can I do on the different lessons?”, “What is Kana?”
- No information about location. When the app is started, the first screen is the Gojûon (“Fifty Sounds”, the Kana training area, see Figure 1). Most of the screen is empty, but the information that you are located at the Gojûon chapter is missing (at the top would be a good place). This is true for all menu elements. In the actual trainings this is no issue as there is a title on these screens.
- Usage: The hamburger menu (Figure 1, top left) is a more or less known element for menus in many apps. Yet it resides unremarkable on the menu screen and I didn’t expect it to contain the whole control flow of the app.
- Another annoying design issue with these app is the need to download every single sound file manually. A sound file for every single syllable on the Kana table (Figure 2) gets downloaded on the first click on these syllable. This is usually fast (less than one second), yet breaks the “flow”. It would be better to include these file directly in the installation or (if the initial app size is of concern) provide a “download all sound files” button.
Figure 1: Start screen
Figure 2: Kana screen
The second (and more important) design issue of these app in my opinion is the used learning method. As I mentioned earlier I had some training in Japanese several years ago. The learning method here in this app is best described as drill: “Look at these 200 foreign characters and remember them”.
The method I learned the Kana with was invented by James W. Heisig (J. W. Heisig/ K. Gresbrand – Die Kana lernen und behalten). It ties every single sign (and the modifiers) to a story which stays memorable longer. Just by looking at the Kana in this app table I remembered some of the stories from that book.
Probably the app can’t incorporate these methods because of intellectual property reasons (which is understandable) but the given learning method for this app wasn’t helpful for me at all. If the designer of the app would have tried to make the learning process a little bit less tedious (stories, small lessons etc.), maybe I would be more positive about the app.
Positive and negative aspects of the contents of the unit
- Stroke order: On thing this app shines is the stroke order. For a “good” Kana sign, the strokes of a sign should be done in a certain order (if done so, some of the smaller hooks at the signs are more natural). Most Kana books show the stroke order with small numbers next to each stroke, but the app actually draws the sign.
- JLPT vocabulary. For every learner of Japanese who wants to have a certificate of his language skill, the vocab list is very important (grammar is in general easy in Japanese, so vocabulary is slightly more important). The app provides a solid test tool (random tests, reappearance of wrong vocabulary, multiple choice for English to Japanese, solution to every answer) so for more proficient learner this app is a good choice.
- No introduction
- General control flow in the menus
- The need to download every single sound file afterwards. Very annoying
- Almost unusable if no (or very few) prior Japanese language knowledge exists
Grade the course on a scale of 0-10.
All in all, I would grade this app with a 5 out of 10. Most of the positive and negative points had already been listed in the previous chapter, but I really want to stress the point of the learning method for Kana (see “Comment on the design”). The method used in this app wasn’t helpful at all to learn the Kana (for me). I’m pretty sure one can learn the Kana this way, but it’s harder than necessary.
The app got a bad grade from me. My main reasons for that are due to the fact that I’m not the right target audience. So if someone with more prior knowledge in Japanese rates this app, he could give a better grade. Also, the fact that this app is free should be taken in considerations, as other sources to learn Japanese like books (the mentioned one for example) aren’t free.
This blog post is one part of the series “learning diary” for a course at my university.
Based on the title for that unit I assume we will learn something about storytelling in the context of didactic.
What have I learned:
People remember stories. If information is wrapped up in a story, it increases the possibility that one remember the information as well.
A story consists of a setting, a plot, a character, a narrator with a point of view, (words, pictures, sounds) and most importantly listeners or readers.
Scheherazade from 1001 Nights is one of the earliest cliffhanger provider.
- Minstrels, Jester (like street musicians)
- Troubadour (for the higher in the hierarchy)
- Minnesinger (in Germany, especially Walther von der Vogelweide)
- Secular song books. They not only told stories and song but wrote them down.
Because of the long winter all family members would gather in one room and one person would be chosen to read a storybook for all members. Usually a child or a guest did the reading.
There is more:
Songs, Music, Poems, Theater, Dance, Political satire
- Story or part of story
- Narrator and points of view
- Time flow
- fictional or true story
- Story / plot / figures
- Most imortant: reception: What happens in the listener
Digital story telling
- Point of view
- a dramatic question
- emotional content
- the gift of your voice
- the power of the soundtrack
Green Eggs and Ham from Dr.Seuss only has 50 words!
Non linear structure
- Nodes and branaches
- attributes for the branches
- multiple stories
My fellow student Alexander Czyrny made a template for his master thesis in LaTeX. The template covers all basic layout settings needed for a master thesis at our University (University of Applied Sciences Berlin). He also added an example chapter with the more advanced LaTeX commands.
