when you hibernate a windows 8, 8.1 and 10 machine, they usually are put into a hybrid state, where the machine is suspended but the ram contents are written to disk, like a normal hibernation. this way, if you run out of battery or something happens (like unplugging the pc), you carry on from what is in the drive. otherwise, it just wakes up like if it was suspended.
#general-chat
slim shard
yeah, hibernate is not hybrid sleep though, I haven't noticed Windows mistaking the two, but I'll pay sharp attention next time around. Often it'll do hybrid on suspend-to-RAM, which I don't care for when running off of SSD
wild temple
if windows doesnt "mistake" both, how do you explain that your pc just turns on randomly when you hibernate?
slim shard
I explain it by suspecting that Windows sets a wakeup timer in the BIOS to assist in auto updates. Are you going to make me look this up?
wild temple
i will tell you that not all bios have that, and the most likely thing, in my opinion, is hybrid sleepm
slim shard
when I explicitly hibernate, hybrid sleep is very unexpected, though again I know hybrid sleep is a default for suspend to ram
wild temple
remember, class hibernation is like turning off the pc, but the ram contents are written to the hard drive
the only difference is that there is an hibern.sys file on the root of your system drive
slim shard
I understand what hibernate should be on a system that doesn't look down it's nose at the user and goof off with the BIOS to generate unwelcome results without asking me :-)
hibernate does not seem to restore from RAM, even in the ridiculous world of Windows
wild temple
one thing you can try is to go to device manager, on your network card, on properties, in the energy tab, try unticking the option that says that the device can wake up the pc
i cant really test that right now, but i will have a go with a vm in a few hours
slim shard
I think that may have helped some in the past, sometimes
wild temple
my pc has an nvme ssd, and boots directly to the desktop, so, its useless
for this test
and hibernation is disabled by default for ssds
slim shard
it also seems to have the nerve to power-on on keyboard interaction
hibernation seems disabled by default in general, probably because users are confused and dumb (in MS-think)
wild temple
but does it power on right away? or does it wait a while to read from disk?
slim shard
power comes on immediately, then with power it runs a POST and some loadingish screen
SSD, so a while is subjective
wild temple
that is so incredibly weird
slim shard
its possible I didn't set it up with full UEFI user-bonage
so I actually get some BIOS interaction possibility
wild temple
the question is: does linux do that?
slim shard
I know windows runs much more tightly with the BIOS/UEFI stuff, I don't run native linux much though, and when I do, I usually leave it on (so no modern hibernate experience there)
I can't torrent linux and transcode 72 hours of video overnight if I turn it off, and finding a middle ground is just inconvenient :-)
wild temple
just as a diagnose, i would shove a live cd in a pendrive and try it
but that may be too much trouble
slim shard
pendrive might not have a swap partition to hibernate to
can definitely suspend to ram in that case though
and I don't recall suspend to ram wakeup being obnoxiously touchy in that case, I could be mistaken though
slim shard

Just like with a camera, stopping down the lens increases depth of field.

I'm trying to figure out, if you take a circle and transform it by a skew matrix such as [[1 1] [0 1]], is the result an ellipse? If not, what shape is it? How would one go about showing whether this is the case? It sure looks like an ellipse, but I'm not convinced that means anything.
bottom: circle, skew circle. top: ellipse, ellipse overlayed on skew circle. ellipse parameters empirically chosen to make it look as similar to the skew circle as possible.

Problem is as in most careers you have someone with a paper that says they know what they are doing to find someone else with a paper that says they know what they are doing but in a lot of cases one or both don’t know what they are doing
The management teams of today don’t typically live in a realistic position for their ability
burnt tendon
Also, I mean, I'm making specific complaints about being a software developer, capitalism is actually pretty ridiculously bad at things and if you were to decide to pick an alternative career, you'd find that they have their own specific complaints there too.
So, like, everything's bad everywhere but at least there's areas where a trans linux foxgirl is totally welcome still.

Inspired by Ben Eater's videos, I figured I'd try my hand at breadboarding a computer. Instead of copying his exactly, I'm starting with an 1802 CPU. I'm also using the Arduino as a clock generator as well as his trick of using it as a bus analyzer.
wild temple
will you build a worse gpu than his as well?
late fulcrum
That would take some doing. The graphics I'm contemplating are an interesting bit of minimalism: the 1802's DMA capabilities can do most of the heavy lifting, so a video interface can be implemented with a counter, latch, and sequencer (which can be a simple ROM).

@cold plank In the schematic for the
Adafruit NeoTrellis RGB Driver PCB for 4x4 Keypad
PRODUCT ID: 3954
https://learn.adafruit.com/assets/62094
There's a 74HCT125 type driver chip on PA03 of the ATSAMD09 SeeSaw chip.
It passes LED_3V to LED_IN of the WS2812B RGB (NeoPixel) array.
That array is powered by VIN which also feeds AP2112-3.3 voltage regulator (which outputs 3.3 VDC from, perhaps, 5 VDC input).
SJ4 decides if the i2c pullup resistors (R6, R8) reference 3.3 V or VIN (~5.0 V).
Q1, Q2 (BSS138) are bidirectional level shifters.
I would say that SJ4 'cancels' their effectiveness when it is soldered to reference 3.3 V (BSS138 is only there, in case you only use 5.0 V logic, as with the Arduino Uno board).
So if you're nowhere signalling on i2c at 5.0 V you can ignore the BSS138pair as they do nothing in that configuration.
You can still use SJ4 to provide for i2c pullups for a 3.3 V signalling system, if you want - the only requirement for i2c is somewhere in your circuit, there must be pullup resistors to the logic level you are using.
That's because the i2c bus cannot source current, it only sinks it. The pullups provide the 'sourcing' of current to signal a logic ONE.
PA27 is labelled INT (Interrupt) and seems to be used locally when you use two (or more) of these modules, using the edge 'finger' connections.
It's probably related to the SeeSaw module on each board, signalling the others, but that's just a guess.
Treated as a whole, your electrical interface to the board (including any copies of it, soldered edge to edge, if you have them) amounts to that STEMMA connection, which allows you to talk to it via i2c.
Where it says "Wiring is easy, solder the four VIN GND SDA SCL pads to wires and then connect to your Arduino compatible" on this page:
https://learn.adafruit.com/adafruit-neotrellis/arduino-code ..
.. there is nothing there about INT at all.
The STEMMA connectors are faily new to Adafruit products, but that product's how-to page would have been authored a long time ago. ;)
It's the same connection, only you don't bother with solder (unless you want to; you still can, if you do, but you don't have to .. anymore. ;)
If you read up on the original SeeSaw module:
https://www.adafruit.com/product/3657
.. you can get some idea of the role it plays on these keypads.

Napkins, too. Some places give you enough napkins to clean up a crime scene. ;)

I usually end up not having enough ketchup in any case... before the plague took our ketchup, I'd ask for extra. Sometimes they'd give me 8923 packets and I wouldn't have to ask for a while, but I always keep the extra condiments and napkins in my car [though yeah, they give you SO MANY NAPKINS still]
I actually will take a bundle of napkins inside from my car to use inside instead of using purchased napkins, lol

I finally found a place that delivers a burger (routinely; nothing to do with our shared personal, recent circumstances).
But .. the pizza place always had a 'hamburger grinder' that was better, anyway, so they win in the long run.
(They make their own grinder rolls in the oven, from scratch, sodium-free.)

at some moment each faculty of our department was hit with an email coming (apparently) from the chair that said "need to talk to you urgently; what is your cell?"
About half responded and got to the next level: text message saying that the department urgently needs to put together some funds and could you buy a gift card and text me the number?
I do not think anyone actually fell for this - even math professors are not that naive. But the chair did get a few phone calls asking "Are you OK"?

I don’t understand how people actually fall for the “we need you to buy gift cards for important business things” scam

The word "con" from "con artist" come from "confidence", meaning it's their goal to build a false sense of confidence and trust, using any tools they can.
Yes, it's true that many of us on here may be fully aware of the tricks these criminals use. But many aren't aware. Many are frightened. Many buy into their message.
Some of these scammers are really good, and you might not even be aware of being scammed until too late.
And it's our job, as people who recognize the scam, to tell our friends, family, loved ones, that these scams exist. That Microsoft/Dell/McAfee will never call them. That the IRS/DEA/CIA will never tell them their SSN is being cancelled. Vacations that sound too good to be true are just that. Too good. That these car warranties, if even legit, are terrible packages meant to rip you off. In essence, a scam.
What advice can we give to our loved ones to avoid scams?
-never answer a call from an unknown number
-ask a lot of questions. scammers hate marks that question and challenge. they want complacency.
-if it's a reputable institution, call their number directly -- after getting the number from a trusted source. Like the bank's number from the back of one's credit card. any legit person would thank you for doing that, and happily give an extension or case number to reference.

@grave crest last time i got the car warranty one about to expire i had an actual person on the other end so i just simply asked which one the 79 c-j5 or the 67 dodge? They hung up real fast 😂
grave crest
@velvet pelican Yep, the ones who first answer are the "filter". If you don't match their criteria, they'll just hang up. [another sign of a "totally legit company"....not.]
But if you navigate past the filter, you'll get a second person -- a "manager". Spoiler: they're not a manager. They are often much more aggressive, pushy, and manipulative. Those are the ones I deeply enjoy wasting their time 🙂
Because if they're talking to me, they're not talking to someone's grandma.

Yup part of the reason i like having not new things. Home warranty ones are great im like so i can get a home warranty on my rv?

The introduction of the round s, instead of the long, is an improvement in the art of printing equal, if not superior, to any which has taken place in recent years, and for which we are indebted to the ingenious Mr. Bell, who introduced them in his edition of the British Classics [published in the 1780s and 1790s]. They are now generally adopted, and the [type founders] scarcely ever cast a long s to their fonts, unless particularly ordered. Indeed, they omit it altogether in their specimens ... They are placed in our list of sorts, not to recommend them, but because we may not be subject to blame from those of the old school, who are tenacious of deviating from custom, however antiquated, for giving a list which they might term imperfect. — Caleb Stower, The Printer's Grammar (1808).[13] https://en.wikipedia.org/wiki/Long_s

There are a lot of facets to game building: some folks get hung up on physics engines, some on control layout, some on timing, some on plot, some on character design, some on backgrounds, there's a lot to explore. I suspect few people have the entire skillset, so collaboration is probably useful for many types of games. The ones I wrote were simple and didn't involve much in the way of plot, art, character design, etc.

There is a reason it takes 200 people to make a AAA game these days.

I had graduated from a 6800 machine with 768B of RAM to the massively powerful Atari 800 with 16kB of RAM, graphics and sound coprocessors, controller interfaces, etc. and figured I'd just sit down and write a Pac-Man clone.

One of my early ones was "Kill the Cities", where you were presented with a 3x3 array of red and green rectangles which were the cities. They didn't move, didn't have shields, didn't shoot back, you had unlimited time and ammunition, and one hit destroyed a city. If, under these difficult conditions, you somehow managed to hit all nine of them, it would print "You win! You hear that? They're cheering for you!" and make a hissing noise. It also had a bug where your crosshairs erased whatever they moved over, so you could slowly make a city invisible by wiping out all its pixels.

or you can use any number of other tools, including IDLE, thonny, vscode, arduino ide, etc
does a happy dance, my package is out for delivery, woot, shiny new cyberdeck and pitft

OS is High Sierra 10.13.6, Mu is 1.1.0.beta.4

that should be a new enough version of mu

@limber jackal It's a text editor.
limber jackal
I gathered as much, with the vim part. I hadn't heard of rvim though. Just "regular" vim, and nvim/Neovim
dusty citrus
I developed the habit:
$ rvim -n ./thisfile.fs
I don't remember what the variants mean. At all. ;)
delicate stream
lol
dusty citrus
rview sets a bit inside the editor to caution you that you only wanted to observe and record, but never interfere. ;)
Like many binaries, called with a different name, invoking different behaviors.
(I assume; don't remember anymore)
Looks like rvim prevents '!command' style shell escapes, or similar.
Try:
:!ls
E145: Shell commands not allowed in rvim
In plain vim the 'ls' completes as expected.
I'm used to 'hostile' BBS environments where you don't want to allow escalated privileges.
(used to be a member on a BBS that starts from a shell account on that BBS' machine)

Normally I'd set up an equation for the area as a function of a ratio of the dimensions, differentiate, and solve for zero (the inflection point should be a maximum).
I had a similar problem in one class, but it was two yards. I came up with a different answer than the teacher did, and insisted I was right, so he had me come up to the board and do it. I drew my diagram, showing the two yards sharing a section of fence, and his face fell as he suddenly realized I had come up with a correct solution, although the math was more complicated.

Hi! I have a problem, or more of a doubt, that I need to solve about the module DS3502. I've already explained on the github, but I guess it's not the right place https://github.com/adafruit/Adafruit_CircuitPython_DS3502/issues/8

@hasty quarry Came out to 7200.
119 119 2
119 x 2
118 118 4
100 100 40
75 75 90
65 65 110 7150
60 60 120 7200 << bingo
55 55 130 7150
The answer, 60 60 120 7200 is suspicously related to the input data (240).
Shouldn't be hard to generalize to any strange input number instead of 240.
(0.25 + 0.25 + 0.5 == 1.0) for example.
1 + 1 + 2 = 4
input / 4 = unit
unit + unit + 2 * unit = available material ln
Like that.
input / 4 = unit
240 / 4 = 60, the unit
60 + 60 + 120 = available material (original input)
delicate stream
2+2 = 10... IN BASE 4 I'M FINE!
static flare
do we really use ten for 10 outside of base 10?
although, any base is base 10, really
dusty citrus
I call 10 in base 2, 'two' in English.
delicate stream
any base less than 10 uses 10
dusty citrus
I call 100 "four" in English.
Or, "two to the 2nd power"
Or, "ten to the second power" if the base was ten.
Or, "Eight to the second power" if the base was eight.
I only call 100 "One hundred" in base ten.
I call it "one double zero" in any non-base ten system.
delicate stream
If I'm reading out 10 in base 2, I say one zero
polar bloom
What about 0xc000, I would call that "C-thousand hex".
dusty citrus
I say "Cee oh oh oh" in my head for that one. ;)
static flare
I'd usually do cee oh double oh
dusty citrus
0xC7042 "Cee seven oh four two"
0xC9137 "Cee nine one three seven"
0xC0000 "Cee oh oh oh oh"
I'd also do "Cee triple zero" for 0xC000
delicate stream
0x00000000 is most exciting BSOD
static flare
I just call that zero
dusty citrus
When it reaches four consecutive zeros my head splits the problem into significant digits and placeholder zeros.
I also 'see' the four bits per hex digit in my head simultaneously. ;)
After working with octal for several minutes, I see those in groups of three bits.
delicate stream
My brain likes to split things in groups of 2-4
dusty citrus
That doesn't work for octal.
To translate from any base to any other base, it's usually worthwhile to first translate to binary.
delicate stream
binary best base
dusty citrus
(at least for specific powers of two)
Base ten is there mainly due to the configuration of our own human hands and feet.
Base 12 is nearby to base 10 and would have made much more sense to work with.
(base 8 too few, base 16 too many)
static flare
I usually do 2
delicate stream
Too bad humans didn't have 12 fingers and 12 toes
dusty citrus
We should fix that in Human 2.0 ;)
delicate stream
lol
dusty citrus
It's probably not solvable though. ;)
All of tetrapoda is 5-fingered, roughly speaking. Hmm I'm not sure that's true.
I think the accurate report is all of tetrapoda has no more than 5 digits per limb.
(none have six or seven or more than seven digits per limb)
Pretty sure some have fewer than 5 digits per limb though, even counting vestigials.
real falcon
me, i would add tail for human 2.0
delicate stream
It probably wouldn't be too terribly difficult to make 6 digit per limb humans... they do exist, that's a base
Prehensile tail
real falcon
yep
dusty citrus
Pretty sure six digit humans aren't with heritable traits.
delicate stream
Eh, inheritability can be modified
dusty citrus
I would say no it can't and since this is a friendly place I'll leave it there. ;)
dusty citrus
There's a vicious style of debate I'd say I enjoy with close personal friends who not only can take the 'hostility' but appreciate the candor that goes with that style.
It's not very well suited to online, except among very old friends.
delicate stream
Online can be hard... often words can come off as incredibly harsh when no harshness was meant, often because one's internal emotional state can color the perceived tone of text
dusty citrus
My close long term online friends are pretty cool, but, sometimes they don't have time to participate, in the middle of something.
So it's good to maintain perspective that there are going to be significant time lapses between utterances, and the timing has nothing to do with, if things are still cordial. Just life intervening. ;)

delicate stream
I'mma order enough to get free shipping XD
dusty citrus
That only works if you're understocked on a lot of stuff you should have on hand.
Usually better to take the hit on shipping.
Though at 16 bux a pop, shipping's getting pricey.
This qtpy rp2040 is Papillon sized. ;)
delicate stream
I'm ordering a lot of sensors and things I have 0 of
dusty citrus
Okay the QT Py RP2040 has a lot of 3-D stuff on both sides of the board.
That's how they got it that small.
dusty citrus
I've never done USPS First Class Mail like this, before (that I can remember).
Not a bad outcome.
delicate stream
It varies XD I try to avoid USPS these days
dusty citrus
Four bux a few days after a fairly large order, so it worked out to get one more order in without cost overruns.
The QTPy RP2040 wasn't in stock when the first order was placed (itself time-sensitive as it contained items now out of stock, or soon to be out of stock).
delicate stream
I've had orders via USPS just... Not show up. Or say they're in my city and then they're across the country and end up being a week late...
dusty citrus
I can't think of an order I was outright burned on, for USPS but I don't use them much. Not yet.

I've had FedEx ship things out of state, then back, from a place that's about an hour from me
delicate stream
Yeah, FedEx does dumb too. UPS seems to do the least dumb
umbral phoenix
for any of them, it all depends on where their hubs are
dusty citrus
My friend who's an aviator and was a FedEx pilot said that FedEx is least physically rough with parcels that get loaded into and out of small aircraft.
I think he allowed that UPS was the worst in that regard.
umbral phoenix
I've come to optimize carrier choice based on sender. USPS Priority is pretty good for me, but I don't get mail delivery at my house, so I have to go pick it up... ditto when UPS or FedEx do their postal-drop rates

A couple years ago, when I first started ordering from Adafruit, UPS would route the packages through most of New England (after going from NYC to NJ). One package touched seven states and took almost a week. But they seem to have gotten much better; the last three orders had less than 24 hours from when UPS picked it up at Adafruit and when they dropped it at my house (or tossed it on the ground at the end of the driveway). I didn't get the routing info on the last two, but the first one that was fast only went through two states (NY where Adafruit is and Vermont where I am).

Late response, but whatcha do is y=x(240-x)=-x^2+240x
2-second derivative to get y’=-2x+240

Then just find where y’ equals 0 (x=120)
