At the time we went, Iceland was one of the few countries in the world that allowed vaccinated foreign visitors. All that was needed was proof of vaccination – not even a pre-entry COVID test. The fact that most people were vaccinated meant that most people were not wearing masks in the city, but this was before even the Delta variant – it seems like so long ago now.

I had been itching to go travel somewhere since the pandemic began, and this was a very welcome nudge towards normalcy. Flying with Icelandair was the same as before: the seat and leg room is pretty comfortable, but there’s no food included with the airfare. The only difference is the extra bureacracy related to COVID, which increased how long it took each person to get through immigration, resulting in long lines after the plane. It didn’t help that we arrived so early in the morning that the food places weren’t even open yet and we had to wait in line while hungry. Eventually, we picked up the rental car and drove into Reykjavik for breakfast. We took the day easy by just exploring Reykjavik on foot, and took a nap in the afternoon when the jet lag caught up to us.

That night, we had probably the most memorable meal we’ve ever had at Tapas Barinn. The great thing about tapas is that as tourists, we get to try a little bit of everything as opposed to ordering entrées.

I even got to try some Flóki single malt whiskey. The smokiness from the whiskey actually comes from the barley smoked using sheep dung, a traditional cooking method. I also got to try some more brennivin like my last trip to Iceland – it’s essentially a grain alcohol (40%) and flavoured with caraway seeds, which gives it a sweeter flavour than something like vodka.

I had visited Iceland a couple years ago, but it was in the winter where there was only 4 hours of light per day, and even then the sky looked like dusk.

This time, travelling there in the summer, I didn’t see the night sky the entire time I was there. I could more clearly see and appreciate the nature around me, like the endless fields of moss growing on the rocks, and sheep freely roaming the fields.

It is thought that the Icelandic sheep were introduced to Iceland by the Viking settlers. Farmers allow them to freely roam around in the summer months, and as winter comes, they round them all back up again.

Like my previous trip to Iceland, we travelled along the Ring Road to see the waterfalls, and the volcanic beaches.

This is what the view at Seljalandsfoss looks like in the summer versus the view I saw in the winter. I had no idea Iceland could be so green. In the summer, people can even walk behind the waterfall, between the rock and the falls itself, but in the winter, the trail is closed because of ice.

Skógafoss looks about the same between summer and winter, except the vegetation is greener in summer.

A kitty even came out to hang out with us! As we were walking, the cat just walked up to us and stopped, expecting pets as a payment to pass through. After that, off it went.

Unlike travelling to Iceland in the winter, there were no restrictions (4WD) to drive up to Dyrhólaey in the summer. As we drove up, I could see why. The road was a set of steep switchbacks on gravel roads that were only a little more than two cars width – and there were no guardrails.

From the top, one can see the endless mountains, or watch the waves crash against the beaches of volanic sand.

The next day, we took a Superjeep tour to see ice caves on an active volcano known as Katla. The reason why it’s called Superjeep is because it can deflate its tires (for icy roads), and inflate them back up again depending on the terrain, but otherwise it looks like your typical Ford Excursion but with big tires.

The ice caves were located a ways in from the glacier. In summer, a lot of the ice had melted, revealing the volanic sand and rock underneath.

Only just now as I was writing this, did I realize we were travelling on a literal volcano, but I suppose it’s safe.

As we headed up the volcano, the lush, green vegetation quickly disappeared, revealing a rocky landscape with a mix of ice and black volcanic rock. Grey clouds covered the sky and it began to rain.

Eventually, the tour guide parked the truck, and we began our volcano hike. He brought his ice pick with him and used it several times to cut steps in the ice.

Despite the summer season, the temperature still felt like a mild winter. But it still meant the ice caves would not be as fully developed as in the winter season, and this could clearly be seen when comparing the ice caves from this trip versus the previous one. In fact, the winter ice cave was really more of a tunnel, while the picture of the summer ice cave was taken from the end of the cave with the camera pointing out.

The ice on top of the volcanic rock looked so alien that several movies used this place as a location for another planet. Rogue One was filmed in the area for the opening scene where young Jyn Erso hides from the stormtroopers. The movie doesn’t show the whole cave, but the similiarity is clear. If the movie had shown the whole cave, one would see why people call it the “Yoda Cave”.

It was nice staying in the cave for a bit as a brief respite from the rain. We made the mistake of wearing jeans for a multi-hour hike in the rain, and our wet clothes just made us even colder. We also got the chance to chat a bit with others on the tour. We met an orthodonist who practised in Greece by the name of Thanos (I wonder if he was aware of the MCU), and another who claimed to be a “voodoo priestess”, whatever that means.

The next morning, the plan was whale and puffin watching. It turned out to be an incredibly bad idea because I apparently get seasick, and didn’t get to see a lot. Even those who did see whales could really only see a small fin barely capturable on camera. Only a small percentage of people get to see the whale flying out of the water and crashing back down. Good thing the puffin watching was on a separate tour so I got to recover from the seasickness, but we decided not to go and instead gave the tickets away to another group that we overheard looking for tickets to the same tour.

Instead, we went to go get some Icelandic hotdogs for lunch. The key things that set it apart are the condiments, and the sausage. In addition to ketchup, and sweet mustard, they also add “remoulade”, similar to mayo with added herbs. The sausage uses lamb, as opposed to chicken/pork/beef.

Next, we headed to the Reykjanes Peninsula and the Blue Lagoon. We reached the tip of the peninsula and stood on the cliff watching the waves crash against the shore. If there was such a thing as the end of the earth, this was it. Despite strong gusts of wind, thousands of birds nested on the side of the cliff. From far away they look like white specks, but one can see them clearly with a good set of binoculars.

Next, we went for a relaxing soak at the Blue Lagoon, a man-made spa fed by water used by a nearby geothermal plant.

The water forms a milky blue colour from the high silica mud, and is supposedly good for the skin. They even sell super overpriced skincare products at the gift shop.

The area is beautiful with all the steam slowly rising from the hot springs with the light cool breeze. It would have felt like a whipping biting wind if not for the hot spring. You just submerge yourself until you feel not too hot and not too cold, and then relax with their cleansing silica face masks and a drink.

After leaving Blue Lagoon, we’d learned there was an active eruption happening at the nearby Fagradalsfjall volcano, and was happening slow enough such that it was OK to go see it.

A short walk from the parking lot led us to the lava flow. The trail continued upstream of the lava flow to the mouth of the volcano.

There were warnings for people to not walk too close to the lava flow because of risks of toxic fumes, but many did it anyway (as did we). Many curious hikers threw rocks on it just to find out that the lava flow had already hardened, even though there were still visible fumes coming out.

The hike turned out to be really long, and we weren’t really prepared to do a multi-hour hike at 20:00 in the cold, wind, and rain. As we reluctantly turned around, we saw people pointing the other and when we looked, we managed to catch a glimpse of the volcano spewing lava from afar. It makes sense now why people call it the “land of ice and fire”

It was surprising to see how watery the lava looked. I expected molten rock to be more viscous. The lava just spewed out in a splash. I felt super lucky to have seen such a sight.

As we walked back, I noticed these hexagonal patterns in the ground. Maybe this is how basalt columns form? From what I’ve read, under certain conditions, the cooling magma can cool in a way that forms these hexagonal shapes.

By the time we reached the parking lot, we were wet and cold (seemed to be a recurring theme by this point). Luckily there was a food truck at the parking lot selling hot soup.

The next morning before heading out to the Golden Circle, we started the day off with a nice brunch at Sandholt.

The unexpected star of the breakfast was the bread. As an amateur baker myself, this is the bread I aspire to make – it’s soft, light and airy with a crisp crust.

Next step along the Golden Circle was Geysir. The geothermal heat creates pressure underground causing the water to explode upward every few minutes. The entire area is filled with geothermal pools, some of which are so hot they’re bubbling from the heat and pressure.

It’s cool just to just stand in anticipation of the eruption. From looking at it, there’s no indication that it’s going to explode at all, and then it just does. At one point, the wind carried the water toward us and got us all wet, but luckily by the time the water hits the ground, it’s cooled down.

From the Geysir, we drove to Gullfoss. Unlike other waterfalls, this one has a unique feature where the water does a zig zag before hitting the bottom.

There were attempts in the past to build a hydroelectric plant here, but those efforts have not succeeded, and since then, the waterfall is now under government protection.

The last destination of the Golden Circle was Kerið crater. It’s believed that the crater formed through volcanic activity. Once the magma chamber emptied, it collapsed, forming the crater. The accumulation of water is not formed by rainfall, but is actually ground water.

On our last day before we left, we got the chance to try more Icelandic dishes. This time we had some lamb soup, dried fish, fermented shark, and some Einstök white ale, a local craft brew.

It’s not often that I would rave about soup, but I liked it so much I’ve been trying to recreate the flavour at home. It’s savoury soup with vegetables, lamb, and herbs/spices. I can’t say I was a huge fan of the dried fish and fermented shark though. The dried fish is served with butter and its flavour reminds me of super tough beef jerky with a light fish flavour, while the fermented shark has a texture of a ham with a soury tang. Perhaps it’s an acquired taste. The beer was great though.

That’s pretty much it for Iceland. We got the chance to try all sorts of local delicacies, and see a piece of nature we wouldn’t normally see in our part of the world. At the airport duty free, I even got to pick up some Brennivin, and a bottle of the Flóki sheep dung whiskey!

You will need:

• WSL2 setup with Firefox installed (mine uses Ubuntu 20.04)
• VcXsrv
• geckodriver

How it works

VcXsrv starts up an X server on the Windows host machine, and what WSL will do is connect to this server to pass on the details of what programs need to be displayed (in this case, the browser window). Geckodriver is there purely as a middle layer for Selenium to be able to interact with Firefox.

VcXsrv setup

This setups the X server so that Windows can display graphical data coming from the Ubuntu instance.

1. Download and install
2. Start it up with the the command line parameter “-ac”. This flag removes access control restrictions for connecting clients (which is okay as long as this server isn’t exposed on the open Internet and that the only client connecting is the Ubuntu instance)
3. Allow connections to VcXsrv on Windows Firewall

The “-ac” flag and allowing the program through Windows Firewall is pretty important. When I didn’t do this, Ubuntu would give me cryptic error messages like “Broadway display type not supported”, but once I set up these access controls, everything was fine.

Bash setup

Install firefox

sudo apt install firefox

Export DISPLAY variable in .bashrc (or for whatever terminal you use, maybe .zshrc, etc.)

export DISPLAY=$(ip route | awk '{print $3; exit}'):0

This will configure your DISPLAY variable to use the IP address listed in the resolv.conf file. The IP address listed there is the IP address of the X server that will be used for displaying the browser window.

Start up VcXsrv as described in the above and then try to open Firefox. The Firefox window should open.

Geckodriver setup

This acts purely as the API interface that allows Selenium to interact with Firefox. Selenium looks for this executable when controlling the web browser.

1. Download geckodriver (make sure to get the Linux one and not the Windows one)
2. Put it in /usr/bin (or alternatively some other folder in your PATH)

Selenium sample on Python

I tend to use Python when running Selenium code, and I haven’t tried it on another language (I imagine the principles are similar). Here is a piece of sample code for starting up the browser and opening up a website, but really any Selenium code can be used.

import time

from selenium import webdriver
from selenium.webdriver import DesiredCapabilities

def execute_with_retry(method, max_attempts):
    e = None
    for i in range(0, max_attempts):
        try:
            return method()
        except Exception as e:
            print(e)
            time.sleep(1)
    if e is not None:
        raise e

capabilities = DesiredCapabilities.FIREFOX
capabilities["marionette"] = True
firefox_bin = "/usr/bin/firefox"
browser = execute_with_retry(lambda: webdriver.Firefox(
    firefox_binary=firefox_bin, capabilities=capabilities), 10)

browser.get("https://www.google.com")

time.sleep(10)

browser.close()

For best results, training should be considered a full time job. One’s entire lifestyle must be directed towards this objective. This lifestyle will also require following the correct training program religiously over time.

All athletes are limited more by their minds more than their bodies

One needs to develop a winning attitude. One needs to combine physical fitness with mental fitness.

This chapter touches on a few mental opportunities for success:

• Motivation – Competitive cycling demands an inner drive to excel. Everything in your life must be focused on the goal
• Dreams, goals, and missions – high performance starts with a dream. This turns into a goal, and ultimately the mission. Are you willing to make any sacrifice, ride any number of miles, or do any workouts deemed beneficial to achieving the goal?
• Believe to achieve – there are bound to be setbacks. One needs to remain confident, patient and mentally tough to power through. Relive each day’s wins, big or small to boost self-confidence
• Mental toughness – when we’re at our limits, fatigue sets in, and the mind tries to make compromises. A fully committed rider gets through it
• Patience – success won’t come quickly. We can introduce incremental change, like: sleeping 30 minutes earlier each day, cutting out 10% of junk food from our diets, etc.
• Commitment and tenacity – there are moments where fatigue says to stop, but the fully commited and tenacious rider finds a way to keep going
• Consistency and routines – the mind and body like regular and standard schedules. Things like jobs, families, and other responsibilities may interfere
• Your high-performance team – surrounding each champion is a network of family, friends, teammates, coaches, etc.

This topic can get rather deep, so there is value in reading other books on the subject and speaking with other successful professionals from all walks of life.

By improving one’s mental approach to cycling, their training and racing will benefit greatly too.

Duisburg

This is a walkable rollercoaster! Its only purpose is as an art installation for city beautification. The track is a walkway with stairs, but the loop is off limits.

Next door is a nuclear plant though. Makes me a little nervous after watching that HBO show about Chernobyl.

Arnhem

Now we’re back in the Netherlands, in the city of Arnhem. During Operation Market Garden in World War II, the western Allies attempted invading Germany through the Netherlands. Allied soldiers (mostly British) attempted to secure key bridges throughout the country; one of which was in Arnhem. The operation ended in disaster, and the Allies failed to advance in to Germany.

The John Frost bridge was constructed on the same location as the old bridge that was destroyed by bombings after Operation Market Garden. John Frost was the leader of the group of British paratroopers that actually arrived at the bridge during the battle. The Airborne Museum in Arnhem is dedicated to the Battle of Arnhem, but it was closed for renovations (out of all the war related museums we went to on this trip so far, most of them ended up being closed…). The city centre itself has the same vibes as other cities in the Netherlands.

Our day was shorter because of our flight, but our next destination gets even more exciting: Israel, Palestine and Jordan.

• Duisburg
• Arnhem

Bastogne

The Battle of the Bulge (known in German as the Unternehmen Wacht am Rhein – Operation Watch on the Rhine) was the last major German offensive in the western front during World War II. The Germans attempted to use this offensive to break the Allied offensive on that front and force the western allies to negotiate a peace treaty. The territory taken by the Germans during the offensive resembled a “bulge” on the map, hence its name.

During the battle, Bastogne was surrounded by German forces, and when the Germans asked the Americans in Bastogne to surrender, Brigadier General McAuliffe famously answered “nuts!” to the German request.

We stayed overnight in the same farmhouse which served as the former field headquarters of the legendary American 101st Airborne Division during the battle. The staff there mentioned that the same family still owns the farmhouse to this day and that some of them had perished in concentration camps during the course of the war.

They even decorated in the interior with old helmets and ammo boxes.

I wouldn’t consider the place in the middle of nowhere, but maybe trying to find it at night isn’t the best idea.

Just look for the tank turret out front I guess!

We tried going to the Bastogne Museum, but little did we know that the Bastogne War Museum was closed between 20. January 2020 to 19. February 2020. I knew it was low season, but I didn’t think it was so not busy that the entire museum would be closed for a whole month! The only exhibit we got to see was the East Germany open air exhibit outside showing off art painted on the tank, slabs of the Berlin Wall on old Trabants.

Nearby the museum was the Mardasson Memorial, a monument dedicated to the American soldiers who fought the Battle of the Bulge. Inside the memorial, carved panels tell the story of the battle.

The weather really cooperated with us today! We had clear blue skies all day, and got to see the the thin layers of morning frost over the vast farm fields.

Liège

The weather didn’t cooperate for long though because it became like this on our way to Liège…

The thing that surprised me about Liège was how seedy it was. We were hanging out around Place St Lambert, and it felt like people were subtlely eyeing us from the side of the street. In once instance, the moment we turned corner, a man glanced at us and immediately started walking in our direction. I glanced at him some more and eventually he went away. Yeah, we didn’t stay long in Liège.

I think one way to explain why it was so seedy was that Wallonia was no longer Belgium’s center of industry like it was in the late 19th and early 20th century. As the industry went to neighbouring Flanders, the local economy suffered.

Drielandenpunt

Next up, Drielandenpunt, the triple point between Germany, Netherlands, and Belgium. It’s also simultaneously the highest point in the entire Netherlands, a miniscule 322.5m above sea level.

Aachen

Not far away from the Drielandenpunt, was the westernmost city in Germany, Aachen. This is where 31 Holy Roman Emperors were crowned. Charlemagne (his bust pictured below) himself had his imperial medieval residence here.

The Aachen Cathedral shown below was the burial location of Charlemagne. The chapel shown in the middle is the location of the coronation of the Holy Roman Emperors. Despite the name, the Holy Romans Empire was neither holy nor Roman, nor an empire.

As a “holy” empire they weren’t exactly unified by religion. It wasn’t solely catholic and had a significant population of Protestants.

It wasn’t really Roman since for most of its history it didn’t rule over what the Roman Empire ruled over (although it did for a time) and its centre of power was ultimately in Germany. Arguably, the Byzantines or the Eastern Roman Empire was the true successor to the Roman Empire. They were a part of the Roman Empire when it fell and it continued the empire in the east until it fell in the 15th century to the Ottoman Turks.

Technically, it was an empire (at least officially) for a time, until their defeat in the Thirty Years War (1618 – 1648), which resulted in the kingdoms within the empire effectively receiving independence from the empire.

For lunch, I finally got the chance to eat Eisbein (bottom dish), a pork knuckle! It’s simmered for several hours in broth and served with sauerkraut and mashed potatoes! If you like meat, this is the dish for you. The above dish is a schnitzel – thin slice of meat (thinned via pounding) that’s breaded and fried.

Bonn

From Aachen, we drove to Bonn to meet up with a friend, who moved to Bonn from Taiwan to pursue a PhD in chemical engineering. We were so full from lunch, we only had a small snack for dinner at a local pub.

Since it was a Bavarian pub, it sold Bavarian specialities like weisswurst (shown on bottom – literally white sausage). It’s a sausage made from veal! The bread in the basket is a very delicious German pretzel. It’s got a nice cripsy outside flavoured with salt with a soft inside.

After dinner, we explored the city a little bit and visited the birthplace of Ludwig van Beethoven. The house is one of the few remaining middle-class homes of the era.

Bonn is also the world headquarters of an amazing brand of gummy bears – Haribo! It was founded by Hans Riegel in Bonn, hence the name Haribo. People who hear about Haribo for the first time usually think it comes from Japan, and are almost always surprised to find out it’s German! The outlet store not far from Bonn city centre has a MASSIVE selection of all sorts of Haribo variants! It’s got gummy bears, sour worms, licorice, and more! I definitely recommend the gummy bears (of course), the frogs, coca colas, and the Phantasia pack!

That concludes our 7th day. The next day we’d travel to more German cities – Cologne and Düsseldorf.

Strasbourg

Strasbourg is in the historic region of Alsace-Lorraine. The unique thing about Alsace-Lorraine is that in the span of 100 years it has flipped back and forth multiple times between France and Germany as a result of three wars (the Franco-Prussian War, World War I, and World War II). As a result, the city shares cultures from both countries. This is super evident in a part of town called Petite France, most notably the timber framing around each building. The local dialect Alsatian, also has Germanic origins.

It’s also the home of the European Parliament. This is where over 700 democratically elected Members of European Parliament pass legislation.

Thus far, in France, I had been speaking my very limited French here and there whenever I needed it. As we waited for the tour, a Middle Eastern fellow struck up a conversation with me in French, kind of just asking us where we were from etc. It was kind of weird, but we went along with it anyway – it didn’t seem like he was a pickpocket or anything. I managed to get pretty far in the conversation in French actually, which surprised me quite a bit. He told me that he had moved to France from Afghanistan after working there as part of the local security forces, and even showed me his old Afghan ID, and a bomb scar he had.

The conversation got super weird when he started asking about our yearly salary, and it seemed like he was asking us for money (but it’s possible some of that was lost in translation). At that point, we totally understood why he started the conversation in the first place. We basically told him that we’re not that well off either and he tried to give ME money, and I still don’t understand what was going on there. When the tour started, it seemed like he was still staying within our general vicinity, which made it even weirder. Eventually he picked up on that and left us alone. We even checked if he followed us back to our car (just in case).

Strasbourg appears pretty proud of their cuisine – even their postcards have pictures of recipes of different Alsatian dishes. One that we had was called Flammekueche (in German it’s Flammkuchen, so it’s easy to see the German influence in the language here, at least in this word). I think the closest analogue that English speakers would know would be a flatbread pizza, but with more French style ingredients like fromage blanc, and uses crème fraîche as a base as opposed to tomatoes.

From Strasbourg, we began our journey to Switzerland. At the border, we bought our vignette (it’s a required sticker on the car for driving in the country). I spoke to the lady in German and I got a nice feeling speaking and listening to a language that I understood again.

Habsburg Castle

Our first destination in Switzerland was the Habsburg Castle. This is where the House of Habsburg began. This is THE Habsburgs that wielded enourmous power in Europe for centuries, most notably the Holy Roman Empire, and the Austro-Hungarian Empire.

The castle looks quite modest compared to other European castles like Neuschwanstein, but this is because it was originally constructed almost 1000 years ago.

Zürich

As we drove through Switzerland, we expected mountain passes full of snow, but there were actually very few mountains along that route! We probaly would have seen some in Zürich itself, but too bad it was nighttime.

We arrived in Zürich just in time for a fondue and raclette dinner, because that’s what the stereotypes say. Of all places we found though, we found the most touristy one. I’m pretty sure everybody in there was a tourist.

As we were chatting while eating, I was trolling my friend, saying he comes from China even though he’s actually from Taiwan, since Taiwanese people stereotypically like to assert that Taiwan is not the same as China. A lady at our neighbouring table heard us and actually confronted us about it. She seemed so pissed off! She seemed fine once we told her we were just messing around, and that I’m from Hong Kong (people from there generally side with Taiwan). But imagine travelling all the way to Switzerland and hearing someone trashtalking your country!

This concludes our fourth day. Stay tuned for day five!

• Habsburg Castle
• Zürich

Our second day takes us to Oosterscheldekering, Ypres, and Dunkirk.

Oosterscheldekering (Eastern Scheldt storm surge barrier)

We began our day two heading back into the Netherlands, to a network of storm surge barriers, designed to protect the Netherlands from flooding. Large sets of doors can open and close to control the water flow coming in from the ocean. They’re important because most of the Netherlands sits a few metres above sea level or lower, and thus are prone to flooding.

As we drove in the area of Oosterscheldekering, we encountered a lot of windmills spinning noticeably in the wind. And I wondered where all the old traditional windmills went, as in the ones with a tower made of brick with four rectangular fan blades . Netherlands has a stereotype of having a lot of them. We barely saw any of them and then it occurred to me that most of them were probably upgraded to use modern technology.

Ypres

Our next destination, Ypres, is known for the many battles that occurred there during the First World War, where the Germans introduced chemical weapons in the battlefield in the form of poison gas. During the course of the war, the town was destroyed, mostly by artillery fire.

The town was rebuilt after the war using German war reparations, with the main square following the original design as closely as possible. The In Flanders’ Fields Museum (the big building in the above picture) is a museum dedicated to the First World War.

Dunkerque (Dunkirk)

Our final destination for the day was the French port city of Dunkirk, known for the role it played during the evacuation of Allied forces from France. The Germans had achieved a breakthrough in France and had surrounded the bulk of Allied forces around Dunkirk. The German airforce was tasked to destroy these forces, so that the Germany army could conserve its ground forces for other operations, but the Germans failed to destroy the Allied forces and over 338000 soldiers were successfully evacuated to Britain.

That night, the locals were having a festival, called the “Bal du Chat Noir”, probably loosely translated as “The Black Cat Ball”. It’s so obscure that as of this writing, an English Wikipedia article for this festival doesn’t even exist. The French Wikipedia describes it as a festival to celebrate the opening of the carnival season (i.e. the Christian Carnival), and that it’s local to Dunkirk.

From what I can tell, it’s kind of like the Carnival in Cologne, where people party in the streets dressed up in costumes. There’s no shortage of reasons for people to party!

Stay tuned for day 3!

The Hague (Den Haag)

The first stop is The Hague in the Netherlands. It’s the home of the International Court of Justice (pictured above). This is the international court that resolves international disputes that the UN is involved in. It was involved in well known cases such as the International Criminal Tribunal for Rwanda to judge the perpetrators of the Rwandan genocide, and the International Criminal Tribunal for the former Yugoslavia to judge the perpetrators of crimes committed during the internal struggles in Yugoslavia that eventually led to its dissolution.

For lunch, we searched around for something to eat and we could try some herring since that’s a popular dish in the Netherlands. We found a street food stall near us not far from where we were and proceeded to go inside and order. One problem though… the entire menu was in Dutch and there was no English to be found anywhere. We stood there looking confused for a moment, before I piped up and simply asked the staff (knowing that the Netherlands has a very high degree of English literacy) what we should order. He simply replied, “herring sandwich!”. It’s raw herring preserved in a brine in a sandwich along with condiments such as raw onions and pickles. It’s got a nice fishy freshness to it (like sashimi), but a saltier and more sour flavour because of the brine. This is going to be one of those foods that I’ll crave once I leave and can’t get anywhere else.

Another cool place to visit in The Hague is the Madurodam – it’s a park built purely on minatures. Imagine famous landmarks in the Netherlands, like the canals of Amsterdam, old town city squares, and palaces, but in miniature form! As a fan of Lego, I can definitely appreciate looking at miniatures!

Rotterdam

Next, we drove to Rotterdam in the Netherlands and stopped by the Market Hall for more food (I’m always down to eat). This time, we had yet another Dutch speciality: the stroopwafel. It’s hard to say no to two thin crispy wafers with gooey caramel in between.

And because I really enjoy eating protein, I couldn’t resist trying some cured meat. I think this is more of a Spanish thing as opposed to Dutch thing though. I found the flavour way too salty for my tastes (and I use a lot of salt when cooking), but I’m not sure what it’s supposed to taste like.

The market hall also has a nice selection of spices – kind of apt considering their colonial past trading spice and other goods in the Dutch East Indies.

And of course cheese! It’s so nice to see all the wheels of cheese, in all these different colours and sizes.

Baarle-Hertog / Baarle-Nassau

After leaving Rotterdam, we headed towards Belgium – well kind of. The cool thing about Baarle-Hertog / Baarle-Nassau is that a border between Belgium and the Netherlands cuts right through the town in seemingly random spots. You could just be walking down the street along the main avenue of the town and randomly end up in the Netherlands, then in Belgium, and then back again.

On our way out of the town, we noticed lane lines that we hadn’t seen before in North America. At first, we didn’t know why the lines were painted like that, but upon closer analysis, the road is simply a road shared by both cars and bicycles and the red section shows where the bikes should be, and the grey area is the section where cars should be when passing a bicycle. By allocating a space for the car to pass, the cars don’t get too close to the cyclists, thus reducing the risk of an accident. How cool!

Antwerp

Soon, we were fully in Belgium in the city of Antwerp and took a stroll in the old town square. The buildings here look pretty Belgian because of the way the roof inclines – it’s as if there are little steps as opposed to a smooth incline (so-called stepped gables).

This concludes our successful first day of the trip! On day two, we will travel to Oosterscheldekering, Ypres, and Dunkirk.

The buildings look old and rundown compared to what people in the west are used to, but I’m told they all have Internet connections. Seeing people selling things in the street is a common sight.

My friend’s mom spoke of how she used to get taken to school on these buggies.

My friend reminisced about the times he and his cousins used to play around this well as children. He spoke about it with a light smile on his face, so one could tell how he missed those simpler times.

I got a lot of strange looks from people in the village – it was obvious to them I wasn’t from around there. How often do they ever see a foreigner around town? Probably never. On one occasion, the workers on my friend’s family’s farm asked his cousin what I was doing there. For the entire time I was on the farm, I constantly felt their gaze. They even made a comment saying how they had never seen a guy with a man-bun before.

Their family is quite hospitable and prepared a meal for us – according to my friend, his aunt is quite known within the family for being a fantastic cook. The dishes themselves were the typical ones like paneer, chickpeas, and lentils, but she really knew how to control the spices. She was so happy that we all enjoyed her cooking and for my friend, it was a taste of nostalgia.

This post is about deploying an instance of Seafile using Docker on a non-standard port (i.e. not 80 and 443). The reason to deploy the app on a non-standard port is usually because there is already another webserver running on that port (in my case Apache 2). In such scenarios, it is necessary to set up a reverse proxy so the Seafile port can be exposed by Apache on ports 80/443. Under typical circumstances, deploying Seafile on a standard port would mean that the app would host itself without the need for Apache 2 at all. This post also assumes Ubuntu 16.04 as the operating system, but in theory should apply to other Linux OS’s.

The process can be split into multiple parts:

1. Setup Docker
2. Deploy Seafile
3. Configure Apache 2
4. Setup systemd
5. Setup e-mail (optional)
6. Backing up the image
7. Troubleshooting

Setup Docker

This guide won’t go into depth on how to setup Docker, but rather the setup guide and more information about what Docker is can be found here: https://docs.docker.com/get-started/

Deploy Seafile

The key page in the Seafile documentation for deploying Seafile within Docker can be found here: https://github.com/haiwen/seafile-docker. The command I used is as follows:

docker run -d --name seafile \
  -e SEAFILE_SERVER_HOSTNAME=seafile.example.com \
  -e SEAFILE_ADMIN_EMAIL=me@example.com \
  -e SEAFILE_ADMIN_PASSWORD=a_very_secret_password \
  -v /opt/seafile-data:/shared \
  -p 8000:80 \
  seafileltd/seafile:latest

I recommend setting up Seafile with an actual secret password because it’s not easy to change once it’s set up.

Note that the port argument shows 8000:80. It means that Docker will use the host port 8000 and the container will use port 80 – meaning that using Docker will interpret requests from my host OS on port 8000 as requests on port 80 in the container. 8000 was used on my setup because port 80 was already used.

Once the command is executed, the necessary files will be downloaded and the container will start and will be accessible on port 8000.

There is also an option to setup Seafile with an SSL cert from Let’s Encrypt, but I didn’t do this because I already had a cert that I wanted to reuse.

Once the server is up, navigate to https://seafile.example.com/sys/settings/ and change SERVICE_URL and FILE_SERVER_URL to match your domain name.

Configure Apache 2

Adding a reverse proxy on Apache 2 will allow Apache 2 to route requests to port 8000, which will go to port 80 in the container. The main reference for this section is this: https://manual.seafile.com/deploy/deploy_with_apache/. This is done by adding a new site to Apache 2. The following configuration assumes that a LetsEncrypt SSL certificate is used.

cd /etc/apache2/sites-available
sudo nano seafile.conf

<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerName seafile.example.com
    ServerAdmin me@example.com

    RewriteEngine On

    # ModSecurity does not process requests.  There is a hard limit of 1 GB
    # with ModSecurity.
    SecRuleEngine Off

    # Whitelist internal IPs for mod_evasive
    DOSWhitelist 192.168.1.*

    <Location /media>
        Require all granted
    </Location>

    # Stuff for seafile server
    ProxyPass /seafhttp http://127.0.0.1:8082
    ProxyPassReverse /seafhttp http://127.0.0.1:8082
    RewriteRule ^/seafhttp - [QSA,L]

    # Stuff for seahub
    SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8000/
    ProxyPassReverse / http://127.0.0.1:8000/

    ErrorLog ${APACHE_LOG_DIR}/seafile_error.log
    CustomLog ${APACHE_LOG_DIR}/seafile_access.log combined

    Include /etc/letsencrypt/options-ssl-apache.conf

    SSLCertificateFile /path/to/cert/file.pem
    SSLCertificateKeyFile /path/to/cert/key/file.pem
</VirtualHost>
</IfModule>

I’ve added my local domain to the whitelist so that mod_evasive doesn’t think my local host is a threat.

There are two sets of ProxyPass and ProxyPassReverse lines. The reason for this is that Seafile is split up into Seahub and Seafile, where one uses port 8082 (by default), while the other uses 8000. These two lines are essentially what allows Apache to read requests from port 443 and pass them on to the container.

Once the file is saved, execute the following

sudo a2ensite seafile.conf
sudo service apache2 reload

Navigating to the site at the Apache 2 defined port should now load Seafile without having to go to port 8000.

Setup systemd

systemd allows the Docker container to be started up on boot, and be controlled like this:

sudo service seafile start/stop/restart

The configuration is as follows:

sudo nano /etc/systemd/system/seafile.service

[Unit]
Description=Seafile Server
After=network.target mysql.service

[Service]
Type=oneshot
ExecStart=/usr/bin/docker container start seafile
ExecStop=/usr/bin/docker container stop seafile
ExecReload=/usr/bin/docker container restart seafile
RemainAfterExit=yes
User=root
Group=root

[Install]
WantedBy=multi-user.target

Once the configuration is saved, shut off the existing running instance of Seafile and then let systemd start it up for you.

sudo systemctl daemon-reload
sudo service seafile start

At this point, Seafile should start automatically on boot, with Apache 2 doing a reverse proxy to the true Seafile port.

Setup e-mail (optional)

Optionally, Seafile can be configured to send e-mails. The reference is here: https://manual.seafile.com/config/sending_email/. The config file should be under:

/opt/seafile-data/seafile/conf/seahub_settings.py

I happen to be using Gmail SMTP, so at the end of the file I’ve added

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'me@example.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER
SERVER_EMAIL = EMAIL_HOST_USER

Backing up the image

After setting everything up, you’ll probably want to backup the Docker image. First, print out the list of running containers

sudo docker ps

Then take a snapshot of the current running state:

docker commit -p <container ID> <whatever you want to call this snapshot>

Running this command lists all the images and should show this newly saved image:

sudo docker images

I don’t have a private docker repository, so I saved the image to the disk and backed up the file by doing the below. Just make sure to actually move the image to an actual backup location.

sudo docker save -o <whatever path you want>/<filename>.tar <the name used earlier>

The image should be backed up now. To restore the image, it’s a matter of running this:

sudo docker load -i <path to the backup file>

Listing the images as above should show that the image was successfully loaded. Running this starts it back up again.

sudo docker run <container name>

Troubleshooting

Seafile logs can be helpful if it doesn’t start up correctly. These can be found at:

/opt/seafile-data/logs/seafile

There may be a need to ssh into the Docker container. The command for that is:

sudo docker exec -it seafile /bin/bash
