Here's another recent SIMD aligner if you're interested: https://github.com/langmead-lab/vargas

I took a look at the code, and read the paper. It seems that they directly calculate the entire 2D DP array, but use SIMD to allow each cell to contain multiple values, one for each query string. My approach uses anti-diagonals instead, but it is fast for one vs one comparisons, instead of handling multiple query strings. Regardless, my goal was to learn some SIMD and Rust (first time for both), so I did not read man…

One thing to keep in mind is for SIMD memory locality is very important; a diagonal vector with a standard 2D DP grid is gonna lead to a lot of cache misses. Just something else to learn about.

I am learning Elixir and Phoenix. And to be honest I am not sure I like either. The lack of decent resources (I mainly use Python and JavaScript with some C#) so I am used to reading a lot of blog posts, I don’t really like the documentation and the answers in forums are over verbose. And then there is Ecto which gives me new respect for SQLAlchemy or even solutions in C#. Debugging is a bit rubbish as well and to to…

"Elixir In Action" is a very good book to start also.

As a native English monolunguist I'm learning Russian. Rust for a side project I've just started. Music production techniques and how modular synthesis works. I also started skateboarding a couple of months ago after around a 8 year break so I'm getting my flat ground practice on my patio haha (although I'm taking it easy for obvious reasons)

Could you say please what is the motivation to learn Russian?

If you have any pictures available (especially of this bridge) I'd be curious to see. Are you tilling? Doing raised beds? We're planting a bit this year and dealing with weeds, etc. has been a hassle (also, most of the no-dig crowd seem to basically advocate using many tons of compost, which is great but not something you can assume a steady supply of)

There are lots of photos in this thread for the stone: https://twitter.com/simonsarris/status/1234186085200207872?s... We're making semi raised beds up the hill: https://twitter.com/simonsarris/status/1246544902193909769?s... With house compost and composted manure from a local farmer. The lower garden is mostly no till with added compost. We're not really sure what we're doing! So I can't really give advice. I usual…

It looks like you may have the same cart that I do. Hint: in case the bearings fail, go-kart bearings are an excellent and higher-quality replacement and they're the same size. I load mine with 200+ lbs of hay at a time and haven't seen any problems since.

How to raise a good human, be a good dad and husband. Relationships take a lot of commitment and effort. It took me a while to learn how to communicate effectively with my wife so we’re fighting problems and not each other. Babies really test your patience. They are hard to reason with so I have to keep my emotions in check and always be calm even if she is throwing a massive fit. But sometimes they really get your n…

It’s been both great and terrible to be cooked up in a small flat with my wife and child. I’m always happy to see comments like this. I wonder if there’s a community for the M(o|u|a)ms/Dads of HN Any tips for communications with partners?

Three tips that have helped with my wife and I:

1. You can usually recognize when you’ve said something in a tone that you regret. Within a few minutes of saying it, try to preemptively and meaningfully say you’re sorry for that tone.

2. If you’re discussing a topic that one or both of you are very passionate about or that triggers high emotions, each person should stop and write down what the other person is saying. Then repeat back what you understood about what the other person said. This helps both people understand that they are being both listened to and understood, and usually calms everything down. (We’ve only needed to do this 2x in several years of marriage, but it’s been helpful each time.)

3. A tough one, but try not to discuss any hot button topics when one or both of you is tired and/or hungry and/or driving.

Finally, someone else in the thread mentioned high ratios of good/complimentary interactions to bad ones. This is very important. Be grateful for your spouse and show it, every day. This will go a long way toward improving most any relationship.

I am learning game development in Godot, specifically with the intention of making an Oculus Quest VR game. I just finished the initial tutorial yesterday: https://docs.godotengine.org/en/3.2/getting_started/step_by_... Alongside that, I am also watching Disney's Imagineering-in-a-Box, which describes how they develop lands and rides for their theme parks: https://disneyparks.disney.go.com/blog/2020/03/enjoy-a-one-o.…

Wow I want to do that too! Are there any existing godot based quest games so I can get an idea what the final product would look like?

There is a tutorial from Feb 28th which contains a finished project. https://github.com/GodotVR/godot_openvr_fps/releases

I design board games for fun and unrealistic dreams of making entire hundreds of dollars. But the part I suck at is making art and iconography. So I'm spending some time learning how to drive GIMP and Inkscape. Just this week I have completely finished the game I've been working on for six months now: http://www.drtomallen.com/half-the-battle.html (unfortunately the manufacturer is in lock-down, so the only option to play it is to print your own...)

I'm still awful at it, but I can now manipulate art from other sources fairly comfortably. And I'm at a point where I can make geometric types of shapes and patterns easily enough from scratch. It's already enough that I look at logos and things differently now, to see how I would go about building them in these tools.

Unfortunately, I still dislike this aspect of game design compared to the fun of lying in a hammock and run thought experiments on the actual gameplay systems!

Develop a checklist of stuff to try: 1. Does the diaper need changing? 2. Does the baby want a diaper? 3. Does the baby want to be held? 4. Maybe some clothing is uncomfortable for it? 5. Does the baby need to be burped? 6. etc. Walk through the list until something works or until the baby + you pass out. If you spend 2-5 minutes on each item it'll take maybe 20-30 minutes to go through it. If it doesn't work the fir…

7. Is the baby hungry? 8. Is it too cold/too hot for the baby? 9. Does the baby have a rash in the diaper area? 10. Could the baby be teething (may start earlier than 6 months in)? I agree, it's good to memorize or even write down these things. Over time, one learns to move quickly through that list, and which items are more likely at what time. (RE 8. it's easy to worry so much about the baby having it warm that you…

These are great additions!

I can't believe I listed diapers twice and left out "Does the baby want a BOTTLE" - D'oh!! :)

Well, the reason to list those steps in the first place is because in between changing diapers, clothes and room temperature, one can actually forget about giving the baby a bottle. I know I did a few times :).

(It's easier now; mine is 8.5 m.o. and we've finally settled into a proper feeding rhythm, so we know when to give food by looking at the time.)
