Also yesterday, while people were mocking gender reveal parties...
Family Member: "What's the point of it anyway? It's either going to be a boy or a girl."
Me: "Well, actually..."
Me: "Gender is not binary, it's fluid, and you might not even know the gender your child identifies with for years or decades after their birth, if they even feel comfortable talking to you about it..."
(I am the "crazy uncle" but so far left of the rest of my lefty family I make them look like Reagan sometimes.)
@rasterweb I'm not at all far left, but feel the gender reveal parties are a bit weird. It's all to let the crazy aunts pick out pink frilly clothes or not. We didn't do any pre-birth testing with our first kid at all. I'd be tempted to suggest waiting till the birth and changing it to a genital reveal party and not bother discussing gender at all. Young babies don't need much clothing anyway. Even at a genital reveal there are cases where the reveal would cause more questions than answers.
@dlharmon You've done bare metal Zynq-7 stuff right?
Do you have any kind of blog or resources to talk about how to set up an extreme minimalist no-OS bare metal Zynq firmware?
Ideally I'd like just a single source file (not generated by vivado, something I can actually write from scratch) that I can just build with arm-none-eabi-g++, put on a SD card (zynq doesn't allow you to jtag binaries to the PS right?), and then boot up and give me some sign of life by poking a GPIO SFR or something.
Ultimately my goal is to experiment with some truly cursed things that are likely incompatible with all of the generated wrappers, petalinux, etc.
Things like having PL be a CoreSight APB bus master that can poke debug registers on the A9s.
@azonenberg@dlharmon I briefly attempted to look into this type of thing, but instead swore off zynq as too antagonistic to this approach. The mindset of the tool writers is so mismatched that it seemed a hopeless, endless, uphill battle just to get to zero and start from scratch. If you do it you are a foolhardy hero. :-)
@rasterweb the question we always ask of old code is "why?" but yet so many comments only answer the question "what?" My new rule: each comment should use the word "to" in it.
@rasterweb that's an interesting comment. I know that type. Typically due to a side effect in an external behavior that's poorly documented and poorly understood I imagine. The comment has the word "to" in it but not in the sense I was getting at. It doesn't answer why it has to go first. I'd guess you don't actually know why? Or the comment might read "this has to go first to prevent explosion". The second "to" is the "why-to" I propose we include in more comments.
The city has decided our house is now worth nearly twice as much as we paid for it in 2013. No wonder greedy real estate bros try to buy up all the property.
@rasterweb But Pete, doesn't the big mac cost 2x what it did in 2013 as well? Isn't this just us getting old and not accounting for inflation? I remember when my Grandpa tried to leave the tip for dinner with a one dollar bill. Is your house a better investment than anything else? Maybe? Or is money just worth half what it was because your govm't printed a bunch.
@rasterweb I'm with you. I described money to my daughter when she was three and she had the same reaction: money is a terrible idea. It's only a great idea if you are the lucky ones with all the money.
I did manage a 5.28 mile ride this morning before the rain. It’s been a while, felt good to get out there again. (I also reported a bunch of potholes to the city.)
@rasterweb I'm not by my computer or I would outline the upper left hand loop, for it looks like a baby shark.
Incidentally I taught some l of the neighbor kids how to play baby shark on the piano this week. I hope their parents think that's as funny as I do! :-)
I'm failing trying mitxela's trick of wrapping a wire around an ironbit for SMD soldering, any one got any ideas? This is a traditional 25W Antex iron it's wrapped on, but it's not getting hot enough on the wire, it boils off flux, melts low-melting point paste but doesn't do anything to existing components:
Todays test program: load values into the A and B registers, add (or subtract) them and loop.
I've got the jump working but the ALU ops are not so pretty. It's inverting each bit of A if the bit in B is set. The circuit for the ALU is all standard gates, and I'd be surprised if there's any bugs in there given the rest of the simulator is working so well.
So it's probably a schematic issue, and one which will take a bit of debugging.
@thor Hmm 6kW+? Have you calculated the voltage drop across those thin conductors? How much power will go into heat at 700mA with that voltage drop? You sure it won't melt and catch fire? I can point you to a table listing ohms per unit length for different gauge wire if you can't find one.
I did a 5.3 mile bike ride this morning and followed it up with a 10 minute walk. The ride was a bit rough since I skipped the last two days due to being ill on Saturday evening.
It was mostly done a few weeks ago, but the BMS that I had ordered had too low of a current cutoff level. That meant that they were conditions in which the BMS mistook the load from the drill as a short and turned itself off as a protective measure.
I ordered a different BMS of the same form factor but with a higher current cutoff level (for a grand total of $1.64) and swapped it in today.
@rasterweb I probably have it in my phone. I have half a mind to call just hear your "answering phone calls" script done live. Do you answer this way only on work calls, or on your personal/cell/off-hours phone too?
I did a 5 mile ride this morning through the cemetery and over to Dineen Park, which was pretty nice. They've got 5 tennis courts and hopefully no pickleball!
It's hard to write a concise sentence when you have to identify the person in the sentence with a title like, "The Edmund R. and Fanny L. Robertson Endowed Professor of Cognitive Neuroscience, Psychology and Human Behavior; Dawes Leadership Chair of Social Science; and Hawthorne-Croft Medical Institute investigator."
e.g.
A new theory by Jim Smith, the The Edmund R. and Fanny L. Robertson Endowed Professor of Cognitive Neuroscience, Psychology and Human Behavior; Dawes Leadership Chair of Social Science; and Hawthorne-Croft Medical Institute investigator, is changing the way we view interpersonal conflict
