They talked about switching back to 16:9 in this episode of the WAN Show three weeks ago (timestamp set at 1:57:54): I didn't watch the full clip again, but I think 2:1 was chosen as a compromise between aspect ratios of popular phones/16:9 displays, but they then figured you can just zoom in on 16:9 content on a phone if you really don't want the pillarboxing.

(for Europeans) what is it like to commute by bicycle in your country?
minibois replied to MC Morrado's topic in Off Topic
Bicycle commuting is great, I love it. I am writing this from my own experience, bicycles commuting for a couple decades now, for school/work in the Netherlands. The thing that makes a bicycle commute so great is that it can be quite varied. Different routes to takes, different speed/intensity of riding up to your decision and what I think is best of all is the fact that you're in charge. When using public transport or a car, you are dependent on many outside factors to be on time somewhere. Whether that is just what routes public transport takes at what time, or what roads are busy in a car. In a bicycle you are much more dependent on yourself. Basically how fast you cycle decides how fast you're going. Things like traffic jams hardly exist, because for every crowded road there is probably one a couple streets over with hardly any people. Plus, it's at least some light cardio, if not more! Bicycles and their infrastructure are also very accessible. Basic bicycles are very affordable, or can be rented. E-bikes exist for those who want to go faster (or can't go as fast on their own), plus bicycle infrastructure is also a form of accessible infrastructure. Mobility scooters, tricycles, people walking, etc. can also make use of it to get to their destinations quickly and safely. I don't see myself as a bicycle enthusiast, I just want to go from A to B in a safe, affordable and quick way. I have taken public transport a whole bunch in my life too, for places too far away. Somewhere in the 4-8km range (2.5-5 miles) is I think a perfectly fine distance for a normal bicycle. Above that, you might want something with pedal assist/a motor, while below that you could be looking at walking distance. Another thing to make cycling more viable is being able to change clothes at work/school, especially if it's a rainy day. I understand that cycling is not an option for everyone and I think that's sad. Not that I think everyone should cycle to work/school/etc., but I think it should be a safe alternative for those that want. Separated bicycle infrastructure is very important. For example my current commute to work is around 5-6km (depending on my exact route) and about 90% of that is on separated bicycle paths, with that other 10% being some residential streets with lower speeds. That makes my commute quite safe. In about 7 or so years I have only fallen off my bike twice. Once my own fault, when going up a speedbump when it was icey outside, the other time when a car hit me on a crossing (where I had priority). Even though (bicycle priority) crossings represent a very small part of my commute, the cars represent the most danger during my commute. I always have to pay attention to cars paying attention to me, often having to use my brakes pretty aggressively. I almost had a limousine hit me at a roundabout even! Anyways, TL;DR: bicycle commuting is great, because it represents freedom and keeps you active. Cars can make it dangerous, but separated infrastructure makes it accessible, not only to cyclists. -
Ducky keyboard repair and USB Type C introduction/explanation
minibois replied to minibois's topic in Peripherals
Can you give some more information on what you did in the repair? Do you also have some pictures of your repair? What kind of cable are you using? -
Ideally you'd ask the company that would be printing/designing this deskpad, they will know the capabilities of their machinery. As a general rule of thumb, 300dpi is the default for anything printed, although higher quality is always great to have. Additionally the image should be the exact width/height ratio for the product it will be printed on.

Your case has two USB ports on the front/top, a USB Type A 3.0 and a Type C port. These both require different kinds of headers (connectors) on your motherboard. The motherboard in your list only has a single USB Type A 3.0 header, but no header for the Type C port. The two warnings are telling you to get an adapter for the Type C port, which would use the connector on the motherboard normally for the Type A 3.0 plug, which that port on the case then needs an adapter to connect to your motherboard. You have a couple options here: Get the two adapters as PCPP suggests Don't use the Type C on the case, only the Type A Pick a different motherboard, which does have a Type C front panel connector (in addition to a 3.0 front panel connector), such as this one: https://au.pcpartpicker.com/product/NMWJ7P/ (it has both a USB 3.2 Gen 1 and Gen 2 connector, which is what is needed)

You can try to use your multimeter in continuity to see if the pads of the sockets connect to the microcontroller. Of course do this when the keyboad is not plugged in. Also check the firmware you have is set up correctly.

Be sure to consult the manual/installation guide of this product, but I believe you still have to bridge the jumper pads on the opposite side of the microcontroller. See this part of the board: I have worked with this footprint before, while the microcontroller is installed on the through-hole pads, the pads next to them are separated, so the controller can be installed on either side of the board (making the PCB reversible). That means you install the Pro Micro with the components facing down and close the pads on the opposite side with some solder. Be sure to consult the manual/installation guide of this product before proceeding though, but what I believe is happening now is that the microcontroller is just not connected to the rest of the PCB.

The +2 part goes in first, with the little plastic notch being locked behind the 6 pin part (because the 6 pin part has the locking mechanism).

Usually there is some kind of latch that needs to be pulled up, or away. Do you have photo of the connector, that way it might be easier to judge what needs to be unlatched. Looking at a video, there is probably a latch that needs to be flipped up to remove the ribbon, but with how many revisions of laptops there are it's impossible to say for sure without a photo.

It was actually hundreds of people ("More than 700" as the report says), due to red/blue flashes in an episode. And not around the world, only in Japan, since the episode did not air outside Pokemon's home country. https://bulbapedia.bulbagarden.net/wiki/EP038 http://edition.cnn.com/WORLD/9712/17/japan.cartoon/ Needless to say Pokemon has been much more careful with these types of effects. The main Pokemon of this episode - Porygon - and its later evolutions also thusfar have never had a main role in an episode since.

FP = Fujitsu Polymer (which that business has since been taken over by Nichicon as far as I can find). 19Cz = their series 271 = 270 uF (27 *101 or 27 + 1 zero added) 16 = 16v The alternative linked the thread above and some alternatives I saw on Mouser seemed appropriate, just be sure to physically measure too, so you know the new cap will fit. I haven't ever soldered on a motherboard before, I can imagine with the large ground planes it can be quite difficult, but I really can't comment on that.
