Fedora Linux (KDE) Set Up Notes

Sun, 01 Mar 2026 01:00:00 +0000

Motivation

Windows 11 has terrible UX and it’s only going to get worse because Microsoft as an organization has no incentive to make it better.

Objective is to find my new main personal OS. Looking at the alternatives, macOS is promising but I don’t want to be fully locked-in to Apple, or having to buy new hardware, or risk Liquid Glass shoved into my face. So that leaves Linux.

I started with selecting the desktop environment first. I picked KDE because it looks like Windows and does not do random nonsensical avant-garde stuff like GNOME.

How Not to Resize EFI Partition Dual Boot Windows + Fedora

Mon, 10 Nov 2025 23:35:00 +0000

I have a Framework laptop with Fedora Linux and at some point I couldn’t install firmware updates. The error was not enough free space in my 100MB /boot/efi partition so I had to resize it somehow.

^ that is me_irl

To give the EFI partition some extra room, I found this guide which said “to create a new bootable FAT32 partition and copy the files from the old one.” Back into the LiveCD we go and sure enough it worked well booting into Fedora. df is now showing the newly added space in EFI.

Kitchener GO Train Progress Tracking

Wed, 08 Oct 2025 23:00:00 +0000

A quick summary for those impatiently waiting for regular, two-way, all-day service between Waterloo and Toronto.

Currently, there is only a single track between Kitchener and Georgetown. Trains going in opposite directions cannot pass each other. They’re building passing tracks at specific spots, timed such that the trains can “meet” at those places to enable limited two way service.

All timeline guesses are mine. Information sourced from train nerd forums and news reports.

To remove all apps from the Dock (by writing an empty array to the Dock’s persistent-apps list):

defaults write com.apple.dock persistent-apps -array

killall Dock

To add small spacers to the Dock to help organize it:

alias add_dock_space='defaults write com.apple.dock persistent-apps -array-add '\''{tile-data={}; tile-type=small-spacer-tile;}'\''; killall Dock;'

add_dock_space

Also helpful: Add Desktop folder to the Dock (drag and drop it next to Downloads)

Photography

Fujifilm X-T30
Fujifilm XF 27mm f/2.8 R WR
Fujifilm XF 35mm f/2 R WR
Minolta MD Rokkor 50mm 1:1.4
Yamato Pax Junior
iPhone 13 mini

Climbing

Shoes
- La Sportiva Miura VS (still deciding…)
- Scarpa Instinct V (capable all-rounder)
- Scarpa Quantic (great for slabs and long routes)
- Scarpa Vapor V (warmup & mileage)
Petzl Grigri 2
Sterling Evolution Velocity 9.8mm
Carabiners:
- Grivel Tau Wire Lock for secure anchor
- Mammut Smart HMS for belaying. It has a Poke-Yoke design that helps to prevent cross-loading and ensures that the carabiner is fully locked. In other words, you cannot close the plastic cover if the carabiner is not locked.
Slings:
- Black Diamond slings, assorted sizes (mostly for building the sliding-X anchor)
Petzl Djinn Axess Quickdraws
Black Diamond Solution Harness
Black Diamond Crag Half-Finger Gloves
Petzl CORDEX Belay Gloves (I like the Black Diamond better though)
Petzl Meteor Helmet

Computing

Framework Laptop 13 (Intel 12th gen, 2022) is my main laptop. I really love the expansion cards which lets me customize the physical locations of my ports as my workspace evolves.
- I will note that once I settled on my expansion cards, they are seldomly changed.
- I wish the battery life was better.
- Windows 11 is mostly okay, but it took lots of work to debloat and tame it. But it keeps getting worse…

Electronics Design

EasyEDA is currently my favourite. UX is quite nice and the desktop app is fully self-contained (runs offline). The app itself is mainly targeted at Chinese customers though, so the product gives off more “Chinese” than “Western” vibes. This means support and documentation are vastly better in Chinese.
There is no credible reason to start any new project in EAGLE or Autodesk Fusion 360 as of 2024.

North Shore Oahu, Hawaii

Sun, 19 Jan 2025 20:41:21 +0000

For around $500 per person, Delta will happily get you from YYZ to HNL and back. This included flying on one of the world’s longest domestic flights, JFK-HNL, for 11 hours. Add another hour and you could have done Tokyo to Toronto.

The temptation of being on a plane over the Pacific ocean at such a suspiciously cheap price was irresistible so I took the bait and gave Delta my money. I knew very little about Hawaii, except for the Honolulu airport’s runway layout from playing I am an Air Traffic Controller ぼくは航空管制官 3.

Outcomes Over Output - Book Notes

Thu, 12 Dec 2024 23:35:00 +0000

Outcomes Over Output: Why customer behavior is the key metric for business Success, By Josh Seiden

Definitions:

Outcome: A change in human behaviour that drives business results
Output: Features / things that are done and work as specified
- This does not necessarily mean they deliver value
- Successful feature results in desirable outcome

The Program Logic Model looks like this:

Resources -> Activities -> Outputs -> Outcomes -> Impact

Looking at this, it’s easy to trick yourself into thinking that once you deliver the outputs, the outcomes will happen. But really, you should evaluate yourself against the Outcome, to assess progress.

Application Layers

Defines the use case and functionality. Specifies how to interpret data coming from specific GATT Services
- Example: Battery Service BAS
Unit and format of the data is calculated and normalized here

Host Layers

L2CAP provides multiple “logical channels” defined by the Channel ID (CID)
This is NOT the same as the 40 radio channels at the physical layer
- The CID namespace is defined in the Bluetooth spec, Volume 3, Part A, Table 2.3
- Usually, CID 0x0004 Attribute Protocol (ATT) is used for the actual data because that goes up to GATT and then the Attributes themselves
- Dynamic CIDs are used for custom applications
- Generic Access Profile (GAP) defines how devices discover, connect, and secure communication with each other. GAP uses L2CAP’s signaling capabilities to manage connection parameters and updates. Similar to a Control Plane.
If ATT_MTU is larger than physical packet size (Link Layer), it will be fragmented automatically. L2CAP is responsible for dividing up and re-assembling the packets, such that from ATT’s perspective it just gets one payload blob.
GATT Services, Characteristics and Descriptors have their own UUIDs for identification
- You can design your own GATT Services and Characteristics; or use existing well-known ones.

Physical Layers

Physical Layer has Protocol Data Unit (PDU) of 27 bytes (up to 251 bytes in Bluetooth 5.0)

More Details

Bluetooth 4.0 was the original “LE”, which was relatively simple. In 4.1, ECDH was added.

Favourite Quotes

Sat, 20 Jul 2024 08:00:00 -0500

On my perpetual sense of doom by lack of progress:

I think anyone else from [University of Waterloo] would say the same thing, but during and for years after, being idle for more than an hour or two made you feel really really guilty, like you knew you should be working or making progress, and if you don’t lose that feeling, you can accomplish great things very quickly. A weekend of relaxing was more stressful and unnerving than anything. I think most people leave Waterloo after they graduate because they hate it so much, it was so brutal that the city itself becomes an incarnation of what you experienced.

Hakone Day Trip using Every Mode of Transport

Thu, 14 Sep 2023 00:26:50 +0000

If you love trains and boats and cable cars, a day trip to Hakone will complete you. In a single day, we took 6 trains, 2 buses, 1 ship, 2 cable cars, and 1 funicular.

Train 1

The Romancecar operated by Odakyu departs from Shinjuku station with direct service to Hakone-Yumoto. The train is called “Romancecar” because there are no armrests between the seats (the seats are 2-2 layout).

We were very excited for the Romancecar (Train 1) to pick us up at Shinjuku.

Tokyo as a First Look at Japan

Mon, 11 Sep 2023 23:36:00 +0000

As I planned my first visit to Japan, I reflected on just how much Japan was in my life. I drive a Toyota, shoot with a Fujifilm, write from a Mitsubishi, and cook using a Panasonic. It is about time that I finally experience Japan at the gemba (現場, actual place).

Armed with a Suica card in my Apple Wallet, I bypassed the long queues of tourists and walked directly to the platform at Narita Airport Station. The first video I took of Japan was a train conductor performing shisa kanko (pointing and calling).

Rock Climbing SOP

Fri, 01 Oct 2021 08:00:00 -0500

Only use words “TAKE” and “SLACK” in positive, unambiguous logic.
- Never say things like “Don’t take”, “I’ll take some slack”, etc…
Use Pointing and Calling for all safety checks
When cleaning, leave the last quick draw under the anchor clipped in as a back up
- On Lead → you would have clipped it in already
- On Top Rope → clip the Belayer end of the rope into the last quick draw
- On Following/Seconding →
  1. At the last bolt before the anchor, leave the quick draw in place
  2. Unclip the Climber end of the rope and clip in Belayer end of the rope
  3. Swapping the rope ends when you are climbing up is not always feasible, use best judgement
Bring some extra locking carabiners on your harness in case you lose/drop one

Sport Climbing in Skaha

Mon, 20 Sep 2021 08:19:00 +0000

The drive from Kelowna to Penticton was beautiful. Highway 97 hugs along the shore of Okanagan Lake and provides constant vistas as we make our way to Penticton.

Penticton is a small city but it’s got everything you need. We picked up some groceries and dinner and settled in at our campsite at Banbury Green RV Park.

As the dawn breaks, the campground is abuzz with activity. I took a short walk around the campground and pretty much everyone who is awake at 6am were climbers. People are starting the day as I am just getting out of bed, despite my body clock being three hours ahead!

Banff with a bit of Kootenay

Mon, 01 Jul 2019 00:00:01 -0500

Moraine Lake

When you search “Canada” on Google Images, this view (cover photo) of Moraine Lake is one of the first results. To celebrate Canada Day, we grudgingly got out of bed at 4am in order to experience this iconic Canadian symbol at sunrise.

Everyone on the left is parked illegally

The parking lot at Moraine Lake was no different from its Pacific Mall compatriot – hazardous to the car, the mind, and the body. The time is 5:40am. Had we arrived 15 minutes earlier, an actual parking spot would have been possible. Anyhow we parked illegally on the shoulder, just like everyone else, ignoring the array of “No Parking - Tow Away” signage that neatly lineup the road.

Icefields Parkway

Sat, 29 Jun 2019 00:00:01 -0500

The 288 km drive between Jasper and Banff is some of the most scenic routes in Canada. The entire length is typically driven over the course of a day, with stopovers for sights and hikes in between.

We set off from Jasper just past 9am. The first stop was the Athabasca Falls, only 30 mins south of Jasper. Walkways crisscross various parts of the falls, while water mist fill the air. It’s probably good times for the plants here, since they are always well-nourished by the river.

Jasper (round two)

Fri, 28 Jun 2019 00:00:01 -0500

It’s been a bit over one year since I was last in Jasper, having spent maybe three hours as The Canadian was being refuelled. This year for Canada day long weekend, I’m going back to actually check things out.

Miette Hot Springs

Driving in from Edmonton was less scenic compared to taking the train. For one, you can’t see Wabamun Lake from Yellowhead Highway. Having breakfast while zooming past the beautiful sunrise over Wabamun Lake was one of the best things that happened on the train.

Food Notes

Tue, 04 Dec 2018 08:00:00 -0500

Restaurant Selection
Picking from the Menu
Shawarma Toppings
Wine

Restaurant Selection

Picking the spot is the battle.

Huge menu with multiple cuisines → probably frozen
You should look at the exterior of the restaurant and have a good idea of the offering. A confused exterior or vibe about what they serve → NG.

Peruse the menu and figure out their specialty
Go for in-season, regionally fresh ingredients
Specialty → Popular → High Ingredient Turnover → Fresher stuff
- Corollary: avoid items that are rarely ordered
Don’t order something they don’t specialize in
- Don’t get pizza at a non-pizza place (do they have an oven?)
- Burgers can also be screwed up – way too dry or overcooked
Backup Strategy: get Hard-to-screw-up items: wings, fried food, smash burgers
Ask the server what they recommend. Their answer reveals a lot. Sometimes they’re transparent (e.g. if they are trying to steer you away from a certain dish because maybe they get complaints on that dish a lot) or their answer indicates they’re not working there a long time.
At fusion spots, trust the waiter to guide you; you’re paying for the exploration

Shawarma Toppings

Chicken Shawarma: Chicken, Fries, Garlic sauce, green pickles (not turnip) – that’s it!

Highway 1 & Big Sur

Tue, 11 Sep 2018 01:00:00 -0500

Driving down Highway 1 was one of my best memories from living in California. It’s time to do it again.

We schmoozed our way north from LA, with brief stops in Santa Barbara and Solvang (the Danish town). By the time we got to Pismo Beach, a golden sunset was well underway. Unfortunately, we didn’t have time to stop to enjoy it…

Solvang, California

We arrived at the campsite catching tail-end of the twilight. After hastily setting up the site, we headed in town to Cambria for some firewood and beverages. Turns out the lady who runs the Cambria general store was from northern Ontario! (She also recommended J J’s Pizza which was brilliant)

Joshua Tree Camping Attempt

Mon, 10 Sep 2018 01:00:00 -0500

I’ll admit, I have a fondness for California. Over the last few years, I had been developing my outdoor skills. It’s time to take camping international now that I’m more competent.

We begin the day packing up our campsite at Big Bear Lake and headed towards State Route 18. The scenery changes very dramatically as greenery gives way to desert.

In the Town of Yucca Valley, the oversized cactuses are reminiscent of those in GTA: V. The town was really quiet and dry-hot. Reminded me of Yuma, AZ.

Northern Ontario hands-on

Fri, 31 Aug 2018 23:09:13 -0500

In May of this year, I “visited” northern Ontario by taking The Canadian on Via Rail. Now it’s time to leave the climate-controlled rail cars for the real thing!

We start our trip boarding the (climate-controlled) Budd Rail Diesel Car (RDC) in Sudbury, for Via Rail’s service towards White River. You know it’s gonna be a lit trip when it begins with trains!

The interior has been renovated and power outlets are available in abundance. Even though cell service is nonexistent outside of Sudbury and Chapleau, it’s great for keeping things charged for the next few days off-grid.

Riding The Canadian

Sat, 05 May 2018 23:09:13 -0500

I like trains. I also like Canada. So, a train from Toronto to Vancouver seemed like a good idea. And an affordable one too, thanks to VIA Rail’s Sleeper Plus discount deals. For a grand total of $2,300 for two people, VIA Rail will take you and a friend from Toronto to Vancouver with deluxe meals and fabulous scenery. Just don’t expect to get there on-time.

Day One: Toronto - Sudbury

Our train departed Toronto about 15 hours late, because the incoming Train was delayed by just as much time. Unbeknownst to us, we were about to experience freight train delays first-hand soon too.

Early morning in Mexico City

Thu, 15 Feb 2018 23:09:57 -0500

Arriving really early in the morning anywhere is … boring. Luckily, we managed to find some nice late-night food in La Condesa after taking one of the first buses out from the airport (~5am). Although the Chapultepec Castle would not be open until 9am, the park itself (Bosque de Chapultepec) was already open at 6am for the joggers and runners.

A short walk from the Castle is Museo Nacional de Antropología, where we learned about humans. The exhibitions were pretty fun to see, and I enjoyed the architecture.

Medellín

Tue, 06 Feb 2018 23:09:13 -0500

Metro de Medellín

After arriving Medellin and taking the longest taxi ride ever from the airport, we finally arrived in the city. We started our journey at Estación Poblado heading north. It was mid-afternoon, and trains were absolutely packed!

The Medellín Metro runs a fleet of MAN and CAF trains, pictured here is an older MAN train. We got to ride both trains and they were so smooth it was easy to fall asleep on them.

Guatapé day trip

Tue, 06 Feb 2018 21:20:35 -0400

El Peñón (“the rock”) and Guatapé is your typical tourist day trip from Medellin, so of course we had to do it.

We booked our tour through the hostel. Our version included a trip to one of Pablo Escobar’s vacation homes.

El Peñón de Guatapé

El Peñón de Guatapé is a gigantic, Arrival-esque rock which seems to have descended from space. But really it is just a huge piece of rock which did not erode over the years.

Santa Marta

Mon, 05 Feb 2018 23:09:20 -0500

A Journey on Highway 90

On the advice of our Bogotá-born friend, we paid a short visit to Santa Marta. The bus from Cartagena (Mar-sol) took about four hours. Highway 90A was being widened, so construction was plentiful.

The bus passed by outskirts of Barranquilla, where armies of young men were eager to provide involuntary car washes for tips. It felt like a medium sized Chinese city at a distance.

Cartagena

Mon, 05 Feb 2018 23:09:13 -0500

Bogotá Stopover

Our long journey from YYZ to Cartagena involved a long stopover in Bogotá. El Dorado Airport is very nice and fancy. We managed to get all our errands done while waiting for the flight to Cartagena: ATM Cash withdrawal, SIM Cards, and Yellow Fever vaccine. A layover in El Dorado is definitely recommendable.

El Centro, Cartagena

Next morning, we headed out to El Centro. The old town is a fairly small area, as is typical of old cities. But it is full of interesting texture.

New York at night

Sun, 24 Dec 2017 13:50:59 -0500

I finally paid my first visit to NYC. Man, it truly is the city that never sleeps. The amount of energy this place has is quite outrageous regardless of time of day.

This is also my first trip with the Fuji XT-1. I attempted to do some street photos at night and below is the result.

Grand Central

17. mai in Oslo

Mon, 15 May 2017 01:50:00 -0500

We arrived in Oslo just in time for Norway’s Constitution Day! The streets were filled with people.

Your browser does not support the video tag.

People dressed up, out and about

I got the full experience … my Norwegian friend hosted a party at his place, and we were drinking champagne at 8:30am.

Gratulerer med dagen !

Oslo itself doesn’t seem to have that many attractions. But it’s a nice city to relax after three weeks of travelling.

Ålesund to Førde to Oslo

Mon, 15 May 2017 01:50:00 -0500

Day 4

Getting to Førde today. The weather turned more cloudy and rainy, which gave us a different view. A lot of driving, and sadly the rain didn’t permit too many photo stops.

Solavågen Ferry

Hjørundfjorden

As we were approaching Førde, the rain eased up and I managed to catch a picture of the Huldefossen from a distance (cover photo).

Day 5

Need to get from Førde to Oslo today, and saying goodbye to the fjords. Very sad day indeed, as I was just getting used to driving mountain passes. But we are taking a train to Oslo, which makes everything okay.

Geirangerfjord to Ålesund

Sun, 14 May 2017 03:50:00 -0500

Day 3

Goal today is get to Ålesund. Should be a much shorter drive than other days.

We were blessed with the most beautiful weather in Gerianger. Also it’s not every day that your car gets blocked by a herd of sheep.

Your browser does not support the video tag.

Found some Llamas on our hike too.

Since the scenic route to Trollstigen was still closed due to snow, we drove up to Gudbrandsjuvet.

Getting to Geirangerfjord

Sat, 13 May 2017 01:50:00 -0500

Day 2

Goal today is to reach Geiranger.

Route E39 between Klakegg and Byrkjelo

Made a visit to Briksdalsbreen to checkout what’s left of the glacier.

The drive in to Briksdalsbreen

It was after our hike that we realised we had made a big mistake. We were planning on driving to Geiranger but the roads were still closed due to snow! Out of panic I called our accommodation and the lady advised we try catch the ferry at Hellesylt.

Land of fjords

Fri, 12 May 2017 01:50:00 -0500

There won’t be as much storytelling in these posts, since we were just driving. Enjoy the views!

Day 1

The road trip is on! Today the goal is to get to Sogndalsfjøra by end of day. A good way to start your road trip is by going to IKEA for their fantastic breakfast buffet. You can never have enough smoked salmon.

Only thing missing in this picture is a train

Bergen

Wed, 10 May 2017 01:50:00 -0500

After contributing to our high school teachers’ retirement funds with some duty-free shopping (Ontario Teachers’ Pension Plan partly owns Copenhagen airport), we headed to Bergen.

The station was so new that ticket machines were still crashing to the Windows blue screen

The new Bybanen (Light Rail) extension to the Airport had just been completed. We had to walk in the dark wet night through numerous construction detours to get there, but it was worth it.

Relaxing in Copenhagen

Sat, 06 May 2017 13:50:59 -0500

The best part about getting from Hamburg to Copenhagen was the ICE ride. You get to be on a train AND a ship at the same time! Truly an experience!

ICE chilling on the deck

Beautiful structure at Københavns Hovedbanegård

We finished most of the things in Copenhagen in a few hours. The city is compact and walkable. The mermaid was very small in-person. Rest of the time was spend on relaxing and taking photos around the city.

Hafengeburtstag Hamburg

Fri, 05 May 2017 13:50:59 -0500

As luck would have it, our one day in Hamburg happened to be the weekend of Hafengeburtstag – the biggest party of the city!

The St. Pauli port was filled with people. A sense of festivity and happiness was in the air, as the streets were closed to traffic and instead became a fairground – roller coasters, carnival games, shops, food trucks, you name it! We watched a demonstration of ship rescue with helicopters and speedboats. The “ship” (which is actually just a barge) is on fire, and first responders rushed to save everyone on the ship.

Amsterdam

Thu, 04 May 2017 13:35:30 -0500

Getting from Den Haag to Amsterdam was super easy with Nederlandse Spoorwegen. We also enjoyed a glimpse of the tulip fields as the train passed by the area near Keukenhof.

Your browser does not support the video tag.

Amsterdam

Sadly it was raining for most parts of the time we were in Amsterdam, but with a hooded jacket we were able to explore most of it.

Den Haag

Tue, 02 May 2017 13:26:03 -0500

Delft

We went to visit the nearby city of Delft, which was only half hour away on the tram. The old town is quite nice, even on a rainy day. The rain kind of accentuates the canals which surround the town.

TUDelft student teams’ Solar Car, FSAE, and Eco Marathon vehicles are on display at the sleek Delft train station. Meanwhile, Waterloo’s own solar car is hanging in Davis Cetre gathering dust.

Rotterdam and trains

Tue, 02 May 2017 10:20:29 -0500

The Thalys Experience

We took the Thalys high speed rail from Gare du Nord to Rotterdam. I was quite pumped for the high speed train, but the overall experience was subpar compared to Taiwan HSR.

First you had to go through security screening before boarding the train. Then once on the train, the interior felt outdated. As the train reaches its service speed, there was considerable vibration and noise. It was disappointing.

Two Days in Paris

Sun, 30 Apr 2017 22:24:47 +0000

First in a series of blog posts on my grad trip to Europe

I’ve heard many things about Paris, and have a fairly good grasp of its geography from playing Cities In Motion. Naturally then, it should be the first stop for my first trip to Europe.
