Draw, draw, draw, draw. Don't try to be good; just draw. Look for one thing you can improve on, then practice until you get a little better at it. Then look for the next thing and repeat.

You are always going to think that you could have done it better. That's the curse of the artist; don't let it discourage you. Keep drawing and then draw some more.

My kid draws all the time and she gets better at it. She also asks me to draw for her and (surprise) I'm getting better at it. Draw a person. Draw a house. Draw a cartoon character. Draw an orange that just received bad news. Draw a lettuce riding a motorcycle. Don't wait to be in front of your computer so you can do pixel art; draw on a piece of paper, draw on your tablet, draw in the sand. Draw on a liquid crystal drawing board (great for throwaway drawings: no mess, quick erase, no drafts left behind).

And be kind to yourself. You are going to think that your drawings suck. I promise they are better than you think (one is always their own worst critic), but also be realistic on where you need to improve technically. Do ask for advice from other people, and take it gracefully.

(You want to do pixel art. Start with the art, and when you are good enough at it, add the pixel.)


i just recently learned that the inner critic your talking about can be tamed. there are ways to practice turning it on and off, setting boundaries for it.

eg - in the Natural Way to Draw - the best exercise (author's claim not mine) is daily homework of making a small composition from memory with a hard set time limit 15 mins. no touch up ever again. one and done. you're mind will want to do more, don't let it.


You know, this is funny because QBasic did not use EDIT.COM. Instead, QBasic was the editor and EDIT.COM was a simple program that called "QBASIC /EDIT" :-)


It was basically the same thing. That's my point.


Modern smoke detectors, at least here in the US, have a 10-year sealed non-replaceable battery.


Interesting. We bought a bunch (5 pack, 6 pack?) from Costco IIRC about 3-5 years ago, and they all take 2 AA batteries, which is great because we've doubled down on Eneloop batteries for everything possible..


every smoke detector i've seen takes a 9volt battery. maybe this is true for commercial units


Most of those smoke detectors are old and already passed their 10-year-lifespan. People keep putting 9-volt batteries in them, but they shouldn't.

If you go look at modern smoke detectors, many-to-most, now have a non-replaceable battery for exactly that reason.


I didn't have to look far to replace my combo CO/Smoke detector or do a ton of hard searching to find one that just took a 9-volt. The first two results on Amazon US for "smoke detector" take 9-volts.


> The first two results on Amazon US for "smoke detector" take 9-volts.

I did the same thing, and the first four results were Kidde and First Alert Smoke Alarms with non-replaceable 10-year lifespan batteries.

It is likely because you recently purchased one, and Amazon has targeted your results based on your purchase history.


thank you for the information, i bought some in 2023 and they all take 9v batteries so i am quite surprised by this


Those exist and are still available but are fairly outdated in the US. The sealed lithium 10-year disposable is the newer standard. And, actually, building codes for last several year requires them to be hardwired so no batteries at all.

The landlord special on older construction (maybe >10 years old, can't remember when the hardwire code went into effect) will usually be the 9v. Because they don't care about you having to get on a ladder to change the battery every year. They get to save $5-10 per smoke detector. Practically any homeowner is going to choose the 10 year option as the batteries don't have to be swapped.


I don't have a dedicated place for announcements and such, but I post on my Bluesky whenever there's a major improvement (@jacobo.tarrio.org).

And you can always star it on GitHub: https://github.com/jtarrio/radioreceiver


Awesome, thank you


Yes, next up is frequency/band management. Recording will come later. Later still, who knows :-)


Is your stick an RTL-SDR Blog V4? Because it looks like the failure happens when accessing a R828D tuner, which should be supported.


Unfortunately I don't know what device it is. Would a lsusb help?


If you don't know, it probably isn't; they brand it quite extensively both outside and in the USB manufacturer strings (it appears as "Blog V4" in the device selection window.)

If it is indeed not one of them, I'd be interested in getting one to test on, so I'd like to know where you got it from. Can you email me? My address is trivial to find or figure out knowing my website is https://jacobo.tarrio.org :-)


I took a closer look. It's a Hama Nano DVB-T (00053330), over a decade old.


Ah yeah, E4000 tuner, those were hard to come by even 10 years ago, so I didn't support them. Only R820 and R828 and compatibles...


Naturalized citizen here: it's not hard at all. You've had the green card for 10 years so the marriage is not even a consideration. For once, you'll be on the "friendly" side of USCIS that wants you to succeed, not the one that wants an excuse to deny.


If there are no issues (that is, no criminal record and no extended absences), then it's a simple and straightforward process and we advise all our clients to handle on their applications on their own and save themselves the legal fees.


I'm Spanish too, so hopefully I can explain. The problem is that everyone treats the SSN as if it were a secret number known only to you, so they use it as both an identifier and an authenticator. In Spain, however, most people know to use the DNI number as just an identifier, using other methods (most typically, physical presentation of the ID card) for authentication.


It's just a convenient way to define a unit of length. Look up the original definition of the metre and you'll see that it's basically the same except for some constants.


The metre was originally defined as 1/10,000 of the distance from the equator to the north pole through Paris. There's a corresponding measure of angle (gradian -- 1/400 of a circle) which has never become widely adopted (although my old casio calculator supported it)


The nautical mile is the length of a minute of arc along a great circle on the surface of Earth. I think the 14.4m figure is wrong; that should be 15.4m, which is the distance covered in 30 seconds by a vessel going at 1 nautical mile per hour.


I'm randomly reading some of the links here. The Wikipedia article on the Chip log associates the 14.4 meters with a 28 second sandglass.
