To err is human – to R is happy pirate noob

Okay, I have to admit it, I saw the quote “to err is human to arr is pirate” and I totally loved it first sight.

Then the love decided that I should try an introductional course in R – and suddenly I am here, writing about this 2-day-experience with a really catchy headline…

So. R. Some of you may know that this is a programming language, very used and beloved by data miners and statistic-geeks. For more information have a look here.

I am not going to do any tutorials on R or so, because I am still a total beginner – but a really happy noob, as you may know. I decided some months ago that the word “newbie” or “noob” is not a negative term for me – I am at the start of something new. So, this is just the beginning of a learning process, another one, because I am learning all my life. 😉

If you want to learn a new programming language, you might take a look to my dear Ninja’a blog on this, this and this blogpost concerning programming and learning programming languages (oh, there is even another one…).

First things first: NO, it is not easy. Learning a new language (no matte if spoken, dead, programming or fictional – now, do not tell me, you never tried Elvish or were fascinated by the Navi-language) is not easy, it takes a lot of time and practice and a lot of thinking and remembering and a lot of mistake-making.

I am currently finishing my dissertation – and it will be done by end of December, hear me!

And I have an amount of 432 objects in my Excel-file that I need to analyse. Okay, I could do it with Excel, BUT: there is a nicer way of building graphics and of analyzing a lot of data (I am really proud of resisting and not calling it “big data” 🙂 )

So, I just managed to combine all my relief motifs of different trees, plants, cornucopiae, sacrificial servants and so on and I ran my very first script with this new defined variables.

And I know, these things are just peanuts for every experienced programmer out there, but I guess for a 2-day-course I am quite successful.

I have to rush now, I need to go to a quite interesting talk – so forgive me for being so late with this post, but maybe I can please and entertain you in your coffee break on this nice monday with his litte blogpost.

Stay calm and keep going, my dear readers!

All the best,

Astrid (also known as the happy noob) 🙂

Don’t check your phone first thing in the morning

Since many of you enjoyed my post on procrastination, I thought I’d follow up with a tip already mentioned here in more detail. It’s her tip to not check your phone first thing in the morning. I have tried this and these are my experiences.

How to do this

I didn’t actively plan on actually implementing this tip. But when I woke up in the morning and was about to grab my phone for the usual checkup (which usually ends up taking much longer than the intended 2 minutes), I remembered Oakley had said to not do this but to first do 10 minutes of work instead. So I thought, I need to get through these bills anyway. And I did that. And I had the first achievement of my day. Then I checked my phone and still lost a lot of time.

10 minutes of productive work instead

Now this doesn’t work every day for me and I’m not enforcing it either. But this morning, I realized I broke the habit of having to check my phone first thing in the morning. I still do sometimes. But I don’t have to. And when I don’t all the effects she described really set in: you are primed for a productive day. After those inital 10 minutes of work, you often continue working because it’s so rewarding. And after the initial urge is past, I sometimes don’t feel the urge to check my phone for hours. This has downsides too, of course. Yesterday I didn’t know our first meeting had been canceled because I hadn’t checked my phone (or at least my work email) since after 5 pm the day before. It was a small setback in the moment. But it’s really a victory. I feel like I’m gaining back my freedom.

The “priming effect”

I also really feel like the “priming yourself for a productive day” thing really works. It’s easier to exercise willpower during the day or at least to overcome the barrier to start getting work done. It’s easier to resist the urge to check the phone. (In some situations I still want to procrastinate, of course, but hey – it’s ok to leave some improvement for tomorrow, right?)

It triggered a chain reaction of positive change

Sometimes things are urgent. But when they are, people tend to try to call you or reach you more aggressively anyway. So you won’t miss anything crucially important. But you gain a few good early morning hours where you can get work done. And after I got work done during the day, I feel that I don’t need to punish myself in the evening by working long hours or checking email constantly. This little mini-change actually triggered a chain reaction of positive change.

Next step: Write down todos the night before so your brain can pre-process them

Another one of those tips I more or less subconsciously implemented is to write up todos for the following day the night or evening before. This lets your brain work on it overnight and you’re more ready to get going the next day.

Maybe the next thing I implement will be to prepare my things for the next day or to tidy up before going to bed. I am really motivated to step up better routines right now 😉

Hope to pass on the motivation,

Best,
S

Fun with SFM – part II: The results

So, hello, dear all, I am back from a very busy family weekend – and I would like to entertain you now with our second part to our SFM-tutorial!

Due to my work at University, I have the opportunity to work with Agisoft Photoscan, which is quite the same as Agisoft Metashape. You can find all the information on this software here – I am very used to it, it is very easy to work with, very easy to understand and you hae all the features collected in one software. Of course, there are other softwares, even a lot of freeware for 3D modelling – I used to work with them as well and I think, the next step will be a comparison of the different softwares by modelling the same object. I am just looking for the time to do it, because: My dissertation has to be (okay, should be) finished by December… so, time is really rare in my life right now…

But this post is all about my little Eros/Amor riding his hippocampus. You can find the information on this example here in my first post.

I opened Agisoft Photoscan and loaded all the images I wanted to use meaning all the pictures I have taken. The first step is the aligning of the images. The software searches for the same points on different photos and matches them.

Step 1: Aligning the photos

Step 2: Building the point cloud

The next step will be the point cloud – of all the points that the software could match on different photos (the best thing is that you get the same point at least out of three different directions) there will be a so-called point cloud as a result. As you can see in the second pic here, there are a lot of “noises” around my object – you can barely recognize Amor’s foot an the tail of the hippocampus.  So, the next step is to clean this mess up. You just mark all the noises around your object and delete it. Another possibility is to mask your photos before aligning them and starting to build a point cloud. Either step will take its time.

In my first post I mentioned the different directions you have to take the pictures from. Here is a screenshot of all the thumbnails of my pics, just to help you geting an idea.

And again, the front view of my model, here already “meshed”.

So, after cleaning you will get a very nice point cloud showing just your object. I just took the side view of this sarcophagus, so my object remains quite flat with no other sides.

After the last step – the finished model!

In detail and without texture the model consists of a grid that connects all the points with each other and gives the actual shape of the surface.

After building the so-called dense point cloud (you may notice the features of the relief getting clearer), we can start with the last step – to build the actual model. As you can see here, I really tried quite hard with the texture as well. The texture can be build out of all the coloring information you have in your pics. This step is not necessary, if you are just interested in the shape of the surface. Therefore, you will get better results without coloring your model, because your eyes might get betrayed by all the shades and colors.

If you want something nice to show your students or your friends, then go for the texture. 😉

Of course there are further things to do on Agisoft Photoscan/Metashape or with other software – it’s a playground, so feel free to try. And remember, I took these images with my phone camera, so no pressure on that. Of course, your first tries may suck, but hey, it’s a process. I am still learning too and I am still discovering new fascinating features and possibilities.

I hope you enjoyed this little post – stay tuned, keep calm and start 3D modelling. 🙂

All the best,

Astrid

Devices and productivity on the go

Today I want to share some reflections on productivity on the go since I just returned from an archaeology and ancient history sailing excursion (inofficial) summer school (it was great and will probably happen again next year as an international summer school on “The Maritime Ancient World” or something, so watch out if you’re interested). The point is that on and before the trip I was, of course, confronted with a difficult choice: Should I bring work devices at all and if yes, which ones are best?

You should not bring productivity devices to your time off at all

First of all, I probably shoulnd’t have brought any device. I had a tablet (my old Lenovo Yoga Tab 2) but I hardly used it – thankfully. I had only brought it in the first place because I hadn’t finished this article, which I ended up not finishing anyway. So that was actually a success, work-life-balance-wise. But on the return journey, I spent a few hours on the bus web browsing options for productivity devices which are suitable for situations where you don’t want to bring the laptop (like on a sailing boat).

But if you really have to, these are my requirements

A device like this should be small and portable, but also not too expensive since I really don’t use it except on holiday. It should comfortably allow you to work effectively in a moment of need (command line utilities and LaTeX inevitably needed for that; also decent RAM).

I am generally a very non-tablet kind of person. I think tablets cannot be used for productivity. I am probably not your average user, but I really want a commandline, LaTeX and some computing power, even on the go. I don’t need Microsoft Word (Learn how you can live happily ever after without it here). On the other hand, I don’t really want apps which I find to be generally very un-usable and non-productive things. A fully functional keyboard is absolutely necessary but since I have small hands, I am much less picky with keyboards than most people.

Also, since I have migrated to Linux completely (by now actually that long ago that I can officially say “years ago”), I ever since am less and less able to tolerate anything else. Insisting on Linux really massively reduces your choices on the mini netbook or ultra-mobile pc (umpc) market. However, on the umpc market, Linux alternatives seem to be taking off recently, so maybe this won’t be an issue anymore a year from now.

But at the moment, most tablets firstly don’t even have a “desktop mode” at all (thus only apps) and secondly, if they do, don’t have a Linux option. Such as my Lenovo Yoga Tab 2 where the keyboard only works with Windowds which is becoming less and less acceptable for me. Of course you can always just install Linux, but tablet-like devices have so many features (like touch screens and stylus support, etc.) that you really miss out on half of the features and I am not really willing to pay for tons of features which I can’t even use. So that makes things kind of complicated.

 

What I found

Despite my non-conventional needs, I have found some possibly interesting options which I wanted to make you aware of. Also, if you are interested in small netbooks or mini ultra-mobile pcs (umpcs), Liliputing generally is a great resource to find reviews of mini computers. They are available as blogs as well as on Youtube.

Many Kickstarter projects feature such mini computers. However, the problem with Kickstarter is that projects might not end up working out, there are huge delays in delivery and you don’t know if there will be any customer support later when the product prematurely exhales its last breath. But if you’re in for cool products which not everybody has and don’t need one delivered to you rightaway, like me, you might consider keeping an eye open on Kickstarter.

Since I am only really interested in products which feature a native Linux option, I will not go into detail with Windows ones. If you are ok with Windows, congratulations, there are many more interesting products out there for you.

The Gemini PDA

The Gemini PDA Android & Linux keyboard mobile device is meant as a smartphone with a keyboard and comes in Android or Debian. However, Debian is supposed to be patchy and it doesn’t really work well for the intended use. The keyboard is too wobbly to be really productive (according to my extensive review research). It looked really promising at first, so I was a bit disappointed by the mediocre reviews.

The Topjoy Falcon

The Topjoy Falcon seemed perfect to me but I missed the Kickstarter campaign and you currently can’t buy it regularly. Also, a general problem with cool gadgets coming out of Kickstarter projects: If they do take off and lead to a regular production, the post-Kickstarter prices are so high that the product really isn’t all that attractice anymore. (Remember, I wanted a relatively non-expensive product for holiday use only.) This sadly is the case with most Kickstarter tec gadgets. But it also features Ubuntu.

 

GPD products

The Chinese GPD company specializes in ultra-mobiles devices. They are much smaller than what you regularly would get because they specialize in this niche.

They have the GPD Pocket 2, the MicroPC (like a 6 inch toughbook), a new ultra-book project going on (GPD P2 Max) and a range of gaming devices. They have a history of successful Kickstarter projects and the prices are great when you get it from a running campaign. The only downside, in my view, is that they aren’t exactly cheap anymore in the regular price and then again, it’s a risk buying from a smaller, less established brand (possibly less customer support, etc.).

They usually release and ship with Windows 10 but they collaborate with Ubuntu Mate for UMPC, so a customized Linux version becomes available shortly later. Which, personally I think, is pretty damn awesome.

Lenovo Yoga Tablets

This is also more like an honourable mention. As I said, I still have a Lenovo Yoga 2 Tab from my pre-Linux era a few years ago. It’s nice and all but the keyboard – which is the essential part for me if it’s supposed to be a productivity device – only works with Windows. (Also, not that I have tried with anything else because I really just want a new device right now.) 

But it’s actually quite a cool product. The bigger one has a beamer function included which might come in handy at some point. I still use mine for watching films sometimes. And I am a big fan of Lenovo. It’s a bit sad that they don’t offer a great Linux umpc. I would totally get that. 

Honourable mention: Paper tablets

ReMarkable

It’s not a netbook, it’s not a tablet either and it’s also way too costly if you’re not going to use it regularly, but I just love the ReMarkable paper tablet. I have never owned it myself but I have tried it out and found it quite awesome. You can use it to read and annotate PDFs, take notes or even make drawings. However, people also have some criticisms on the software and it’s really quite an investment (around 400-600€ depending on whether you can get a special offer). Paper tablets are interesting for academia people because classic ebook readers aren’t great for PDFs but papers mostly come in PDF form. Many colleagues use ‘normal’ tablets for this exact purpose, but that’s another screen your tired eyes have to look into. When I work a lot and want to get reading done, I am usually quite glad to not have to stare into another screen. Also, there’s the thing that the blue light wakes you up at night, etc. etc. etc. So the ReMarkable doesn’t have as many features as a tablet, but in harmony with the Digital Minimalsim principle of non-multipurposing, it thereby also comes with many less temptations for drifting off.

E-Pad

Also, during my research for going more digitally minimalist, I came across the E-Pad 10.3″ E-Ink Android Tablet & eReader with Pen (also a Kickstarter thing) and it sounds really good. But I actually has apps which was a reason for me to reject it at the time since I didn’t want to many options for distraction. Now, looking back, it doesn’t seem so bad though. (I found this review really interesting. A plus is that it as access to full Android and not a proprietary system.)

 

Conclusion

So, that was it for now. It maybe wasn’t an overview over the more common products. But then again, you can get that from somewhere else. Maybe this was helpful to some of you.

Best,
