I don’t have super tight deadlines so I’m okay with a few extra days
Interestingly, I use DHL from where I get PCBs because it's the cheapest AND it's the fastest... and it almost always beats the expected time. My current shipment says it'll be delivered on Thursday but I know it'll be here tomorrow.
USPS is usually right on the money with their expected delivery times for me
Interesting enough is global mail will deliver sooner than my UPS package at the current rate things are progressing
FedEx/UPS I haven't had enough shipments with recently to say anything one way or another
Hmm
Idk why DHL is always the most expensive option for me. It might be that they don’t have as big of a presence in Utah as other places
It's all about where it's coming from and going to. USPS stuff for me is generally local-ish and rarely from really far away (AKA other coast).
So, if it's next day delivery... it arrives yesterday? 😛
In nearly EVERYWHERE that DHL is offered that I've seen, it's on the more expensive side of things
Except from PCBWay
There's a handful of options from there that are "cheaper" but take about nine times as long and are only like. $5 different
And if I'm already paying $20 for shipping, paying another $5 for having it here two days after completion vs 2 weeks is... yeah, worth it
Yeah, once I have a better way of cushioning shipping costs, I’ll probably stick with what I have. Chip shortage is sort of making it hard to make new products anyway
UPS, USPS, and FedEx are all OK here. I don't see DHL for residential at all here
As far as I'm aware, DHL doesn't do US-to-US deliveries, only international stuff.
I've had deliveries where I could tell it was "Take box off plane, drive straight to house" because there wasn't enough time to do anything else between scans.
Better than not at all, lol
That would explain it, lol
Not many people order international packages
Doing a retraction test right now, wish me luck 😬
I usually just order from China if not from the US, and I think that's usually China Post then USPS
That would be previous day shipping
That would be cool

I ordered cameras from https://www.hobbyking.com and it took about a month to get here on DHL
Hobbyking - the world's No1 Online Hobby Store. We stock a huge selection of RC products from Planes right through to Drones and all accessories. Visit Us Today.
yep, standard shipping from China takes... a significant amount of time
Printin' a benchy, nothin' to do...
🙂
What were you printing before?
I'm printin' up a Nerf gun scope soon
A bed leveling test that I was (mis)using as a babystepping calibration print
Oh, I see 😆
ya, lol
Has the Python discord server's logo always spun at 100000 rpm when you hover over it? It's kinda a poor design choice, it makes me dizzy 😆
They change it up regularly.
Better to change it up than to leave it the same forever, I suppose. I prefer Adafruit's occasional changes though
On the other hand, there are some companies out there that pretty much haven't ever changed their logos and at this point they'd better not because there's too much momentum behind it
I just solved an AI problem it took me 30 hours to solve
Using regex scipi numpy and CSR source class
Mac and AC3 mapping algorithms
That must be fun to take a break from!
Yeah I had 1 day left until deadline also
😬
There should really be a youtube music livestream that's called Music to listen to when 3D printing a Benchy
Like I had gotten it Thursday night I have been hard at work for awhile
Well, glad your AI struggles are gone for the moment! Personally, I could do with a challenge like that now, with COVID and everything 🙃
Oh it’s a map coloring problem you have to color each state of the United States a different color
And you have another table of which stste is connected to which state
But all the data is in one file
Honestly, I don't think I follow, but enjoy some peace and quiet free of Green: 53.0% confidence (my interpretation)
Lol
A periodic table,engineering formulas,math formulas in the back seats of a car would be awesome. I've never seen this before. And photos of great people from STEM.
Excited to be featured on someone’s laptop 🙂
If I take out a single transistor in the middle of an Intel processor, will the processor still work?
Assuming you could have tweezers and nm precision, probably not.
Worst you might cause is some bit errors
But more importantly, transistors is more of an abstract or simplified way of looking at microcontrollers. Gates is more appropriate.
I think @late fulcrum has mentioned before that transistors in CPU marketing is kind of misleading
Take a gate out of a processor and you could do probably a bit more damage 🙂
It depends on the processor too. A 4004 has 2300 transistors, so you'd be removing 0.04% of the transistors. An i9 has 77M transistors, so you'd be removing 0.000001% of its transistors.
If it's something in one of the cores, you might have other cores working (this was the idea behind using only 7 cores in the Cell/BBE CPU)
Hello I’m new here!
The Intel must have some defense system in case of a single transistor in the middle not work, don't you think?
Like when we use lights in paralell in houses, not in series.
Hello! I’m new here and have enjoyed looking over the site! I use my Pi’s for NOAA satellite reception and satellite image processing.
Sometimes they will have some extra capacity, like putting 9 cores on the die and only letting 8 run, to absorb some manufacturing flaws.
I always find these light projects in houses amazing really. This one is LED light. :)
Probably not

Such a nice car 😍 ✨ 💯
My grandfather had an old Chevrolet truck.
Actually one of the first words that I spoke when I was born was "Tivole" trying to say "Chevrolet".
You should put a sticker in with each order XD it was hard to get it off the package without ripping or losing the sticky
I plan on ordering some smaller stickers soon
It cost me about $5 to fill these with switches :0
Oh wow
Ohhhhh
And a display to go with it
😎
And this, which was originally like $35!
🌈
And cheap lead free solder!
Micro Center
I wish they were as common as Best Buy
I thought I recognized that style of sticker
Microcenter is the best
Best toy store!
... I dunno what I planned to do with these breakout things, lol
I also got a HalloWing
"I don't know what I'm going to do with this but I'll find a use eventually!" is why I have too many things.
I don't really know what I'm going to do with stuff I buy either, but I built this over the last couple of days
For the first time in ages, I have batteries with connectors!
I just realized the one solder has gold in it
Gold is an odd choice for solder, as it can form weird intermetallic crystals. Silver, however, is common (as in my favored 62/36/2 solder).
The stuff I just used is 99.3/0.7 tin/copper, and it doesn't seem to like my soldering iron... not sticking to it
Wait no it's silver, I'm just too sleepy
96.5/3/0.5 tin/silver/copper
hah
hey captain kirk hows things in enterprise
I am still in about the final of season 1.
They are great.
nice lol
Better than what I expected.
It took more time beucause I'm watching Loki and the Terminator series.
classic or more recent one?
All.
cool 🙂
In high school I parcially read a René Descarte's book.
Have you ever read any of his books? (In your profile it is writen " I exist... I think")
Oh...
its from, "I think, therefore I am" which is yeah by him
Is it like mocking René Descarte's quote?
not mocking, making a joke. basically I doubt my own existance lol
Oh I see.
it ironically shows that I does since I think
When Rene Descarte was a kid everyone tought he was going to die, because of his healthy, so the teachers felt bad about this and allowed him to miss classes and then Rene Descartes used all of this time studying by himself.
He did not die with time, and everyone got surprized, and also got very surprized that he was a very good student.
nice. unusual path of education
He created the cartesian graph.
Students in schools and universities all over the world use it basically everyday.
Cartesian ?
cool 🙂
I like Rene Descartes
He lived in my city for a little while.
That is incredible. What is the name of the city?
It's Breda in the Netherlands. He joined the army there in the early 1600s.
Wow...
It's believed that he got interested in maths while he was there.
In South America we do not have this physical relationship to the most fun things we read in history. Too much. (Or even at all)
Didn't the discovery of the "New World" start in South America?
I think that was a pretty big deal 🙂
Enn... Actually yes and no.
It was more like Central America the first Cristovão Colombo's travels to America.
And there are some evidences that others non-aborigins came here before him.
Trade winds.
like vikings if i recall right
`` '
I read that was Asiatics.
the somebody people traveled west to east thru the americas way up north iirc
The humans ancestrals traveled Alaska to the south of South America, eating and then moving to other place.
yeah there was never any human evolved on americas, humans had to get trip over there
so native americans was there much earlier than any other
This book talks about it. Geoffrey Blainey is nice. It goes from very very early history to Nasa in the moon and computers...
Dorset Culture iirc
Camelids went from east to west towards siberia area
lamas and such
I think there's a camel species that stuck around near the land bridge, very distinct from arab world camelids.
/gobi desert maybe
I read it in 9th grade.
Great buy. It is an about 450 pages middle size book it costed about 5-14 dollars here at the time.
They actually have some evidence now that puts this into question.
I don’t remember the source but there is a lot of evidence contesting what we know about Native Americans (north, central, and south).
in what way? that they cove over in first place?
Well, more based on how and when they got here.
They’ve found evidence that predates that Alaska/Bering Straight ice bridge theories
@tardy badger i didnt explictly state how they crossed over. just the fact that they did
I was more responding to the “came to Alaska” part mentioned
Doesn't really matter .. all knowledge is subject to uncovering of new evidence. ;)
I lived like right next door to the Clovis dig site. ;)
Passed it often on my motorcycle.
Everything's a lie and nothing is real
ok but I didnt say anything about alaska either? 🙂
I made a good case for the opposite conditions, just yesterday.
I am so thankfull to be born in this time. Imagine, travelling always down to south, eat moving, fighting against predators, creating fire with dry wood friction,etc...
I didn’t say you did, Kirk mentioned it
Every time to eat have to kill a lion.
No knowledge about nocive fruits. Hard times.
ok why i asked is because you quoted me
Anyway, I tend think of the sea faring theories of exploration of early visitors to the Americas.
Trying to do 2 birbs one stone
lol ok
They have that song on some TikTok videos that’s like “uhh uhhh yeah yeah get it” with a really bouncy beat
That’s what that birb reminds me of lol
It is amazing how we went from this situation to build books,air planes, smartphones, computers, cars,writing...
It’s amazing how fast technology has accelerated societal cycles
It’s also strange to me that we went to the moon but kind of gave up after a few missions
We the US could have been the first country with a moon base
sit out there on the regolith, in lawn chairs, and watch the Earth.
Or try to jump into space, just don't wanna forget the rope
Generally speaking planets and moons are actively trying to end your days when you go to visit them.
But now we sit on our computers and phones squabbling about certain old people with Toupees
Technology has made us both really intelligent as a species but naïve individually
Clarified 🙂
Everyone is old
lol
Time to finish this French press coffee so I can make my way up the road to the office (yuck)
I wish coffee woke me up
All this time working remote and then getting slapped on a project with no clear direction or objectives that forces me to try and make multiple trips to the office a week
Weeeeeee
I’m trying to do my part to not pollute as much and here I am, polluting away in the worlds largest cereal bowl
Lol
Salt Lake Valley is a massive bowl that traps pollution
Oof....
Heat danger
goble worming
take a mad max class at the community college
not as bad as last one but yeah
It's like 90F in here
don't skip the wrist-mounted ____ day.
I run the air conditioner 24/7 in this weather. And use a 30" fan in that room's doorway to distribute it to the rest of the floorplan.
Can't run the AC in here right now... Insufficient breaker capacity
The ACU will cycle rapidly without that fan - every 6 to 9 minutes. With the fan, runs continuously, due to the increased heat load that the circulating air is providing to it.
I think this one's 1100 Watts and is a 120 VAC window-shaker unit.
10k BTU I didn't go all the way to a 12k BTU unit even though they were similar in cost.
Oof
12k BTU would constantly cycle .. too much air conditioner for the heat load presented there, most days.
An 8k BTU unit would almost never cycle, even without that fan, most days.
So I would have gone 9k BTU if they made them. ;)
1100W AC, 1200W PC... Click
How the heck is your PC 1.2 kW??? Mine struggles to exceed 200 W of draw.
250W for the CPU, ~475W per GPU
Ezpz
Actually that's the one in the other room, which also couldn't be on at the same time until I upgraded one outlet to 20A
But the one sitting here is like 750W and will trip with the AC still
Well, sometimes... It can spike over 900W sometimes
Good morning. Any other Emacs users out there who have gotten Emacs working on Apple silicon?
Have a new-to-me M1 Mac Mini and I'm just getting around to Emacs install, which I've been putting off for no specific reason.
I am already driving the car in the streets in a practical driving class. It is a lot of fun.
Me driving. Very relaxing and enjoyable.
I hope you're not holding your phone to record...
No, it was a support for smartphone that the car has.
It is built-in.
How am I going to hold a phone fixed like this and make curves like that? Not possible.
I've seen people do it
I’m a 16 year old and I drink quite a bit of coffee. Sometimes I notice it actually gets me a bit too alert, and I feel things like paranoia and chills. Only like maximum one (caffeinated) cup a day or every other day. Is this harmful to my heart’s health?
Kinda been wondering about that recently
Thing is I don’t exercise as much as I should, so my heart is probably not too happy with being modified in that way
1 cup a day isn't a lot, but you might be highly sensitive to caffeine. I'd talk to your doctor to find out
Yeah I’ll probably bring that up
One time I had two cups actually, way too close to each other too
And I was in a different plane of existence for a couple of hours
Lol, yeah, you're sensitive
I drink 2 cups a day most days, and can drink as many as 6 vefore starting to feel things
Inorite XD
WHAT?!
HEHH?
Dude…
I’m Colombian
I’m supposed to be immune to coffee
Such a disappointment
I can also drink, like, all of the alcohol
Ozzy Osbourne
(If you don’t get it, Ozzy is a mutant who can drink bottles upon bottles of alcohol like water, and feel nothing)
It helps to not be human XD
But like, by mutant I’m not joking, there’s actually a malfunction in his DNA
That makes alcohol like water to him
Is that a Micro Center flash drive? :O
The purple flash drive plugged into the USB Host shield, lol
Ah yes that doesn’t exactly stand out against the background
lol
I see it now - lol
I mean what else - a couple of Zigbees? Photons?
I couldn't bring myself to mix a Gateron MX Red in with the Kailh MX Reds that came with my MacroPad and I feel strange about that
Am I crazy?
Razer just announced they phantom keys
Not crazy, different feeling keys can really mess with your typing
Phantom keys sound like something I would not like
just light make it shine
its nice to see more coiled cables too
Ohhh, key caps... that's a different story
I am hearing people saying the word "crazy" more than usual here in my city, everywhere I go. Maybe in the future Google will be able to record people words (not phrases for privacy) and make those graphs showing the usage of the word in respect with time. For everyone in the whole world.
Like... nGram?
Google has a word history. You can see the usage of the word in every year but I think they get this data from books and articles.
Yeah, there isn't a good way to catalogue spoken language usage without crazy privacy violations/concerns
It is in the street! You can not prohibit to record what people say in the street. You are not recording faces.
You can even ignore the caracteristics of your voice and focus on the words.
You can't just record everyone's conversations on the street, there can still be private conversations in public places -- being overheard is different than every sound being recorded
The voice isn't the important part, it's the content [the words]
except the NSA they record everything
national security
Crazy in writing peaked in 2014
I think it's because "crazy" is kindof becoming a tabboo word in this new age of mental health awareness
In the context of the US, It's technically only illegal to record voices in the context of private conversations. In places where there is generally no expectation of privacy, voice recording is legal. Ethical concerns are a different story...
I think it gets into grey areas -- like, say, you're in a public park, but then you go far away from everyone, and talk quietly to your partner, you're expecting nobody is listening to you. So you have an expectation of privacy in a public place
Well, yes. I did say "In places where there is generally no expectation of privacy" because there is a line drawn, even in places that are technically open to the public.
So yeah, you can't just record everything
Agreed.
You can not say something if you are not completelly sure of it. This is what I wanted to say.
This is less of a serious comment and more of a running gag...
My father tells me exactly this, preciselly this.
It is serious and important to me.
I mean, for 13 years the NSA collected phone and text records and listened to conversations of of all Americans
That’s why Snowden is on the run, because he blew the whistle on it
loud encrypted noises
It's not literally everything, but definitely more than enough to turn some heads.
It’s also not improbable that the government is still collecting that data
And the Illuminati
Lol
I’m just saying the NSA sort of operates in an extremely grey/gray area due to authorizations like FISA and other legally dubious infrastructure they have.
CIA too
Yeah
So it’s definitely something that should concern people
It should also concern people that private companies also have massive amounts of data mined from us daily
Especially from conversations like text message and non-technology involved conversations.
Do illuminanti obey their parents?
Their own parents?
All
Lol
So excite
👁️
If it is true what you are saying they are absolutelly wrong.
It is like a 3,15,20 years old kid commanding it's 40 years old very experienced own father and mother.
oof
@wary herald
This for me is ugly.
But we are all speculating so.
I agree
I’m not speculating on being watched and surveilled by my own government and private companies
It’s a matter of fact
🙂
And the US government is surveilling billions of people globally
It’s a matter of National security to keep tabs on the world
If Roz did not obeyed her parents, she would not know law, she would not study, she would leave mess whereever she goes, clean herself properlly in the bathroom... etc...
She would not eat with a spoon properlly.
You can’t try to fit your world view into everything.. unfortunately not everyone views the world in such a way
Roz always makes sure to apply copious amounts of sewer slime to her skin in the morning
While she watches you
She would not care about what is right.
She would not be Roz.
She would be just a stylish voice.
Plenty of people don’t have good relationships with their parents and live fulfilling lives
Saying "I am watching you Wozalsky"
Plenty of people grow up fine without their parents
Yup
Honoring your parents has nothing to do with doing everything they say, because your parents are still human and can lead you astray. It’s about being a good and honorable person. The greatest honor to your parents is living an honorable life regardless of their views or opinions.
Some little have horrible, abusive parents who teach them nothing, but still grow into good, hard working, smart people
It’s showing you can do the right thing regardless of insurmountable odds
In the dictionary honor = obey.
Too.
Honor has many definitions
This one is my favorite. It shines for me.
That's not what that definition means in English
And in the Bible where the “honor thy father and mother” is connotations as to bring honor to or to bring respect to
It doesn’t mean “obey blindly”
I mean, you could call it "obey" in the context of a contract, but that's because a contract is a set of rules and guidelines to follow, so honoring it is obeying those rules, but that's not the same as honoring your parents, very different context
To go further, the Bible even references that parents are not always right and they should be careful in their rearing of children to not stir their children to anger
Mhmm
One of the rare times I can put my Bible college learning to work
All I’m saying is the context you are using isn’t the same. And context matters for meaning.
Sure, you like structure and sequential living. Nothing wrong with that
It is binary to me.
Unfortunately it isn’t binary to a majority of people
And the law doesn’t see it that way either
Nothing is truly a binary in life
If your parents told you to steal, if you were to “honor=obey” them, the law wouldn’t care if you were “honoring your parents”
Yup, still illegal
They would care that you broke the law
Anyway, beating a dead horse here
In other news! I finally got my reel of sk6812mini
Aka neopixel
🙂
What parent will tell a kid to put a hand on the fire?
My second reel
An abusive one
True. :/
What I believe is that even the wrong parents will they the kids to be right in the wrong.
If they feed them.
You have an optimistic view of the world
Hold onto that
Good kids can still come from terrible parents. Not because of the terrible parents but in spite of. For them it is not honoring, it is survival
We're doomed when we run out of silicon LOL
Generally doomed
Wait we’re in the military now?
I’m this army we have Captain Obvious, Major Pain, and General Observation
They to not send them to the snakes.
This is what I mean.
I tend to disagree.. plenty of parents kill their own children.
You see it in the news every day
Not trying to be dark, this is just reality
There are a lot, if not a majority of good and great parents out there.
But not everyone is so stable and cheerie
BEATING A DEAD HORSE
I’m trying to fix an installer at work to run on a really expensive simulation server
Suddenly, Lokis
Is that you?
Lol, no, I ain't that cute
Same
If only
This is cute.
This Loki girl is not in Roz's league.
I wish I had a cosplay body
But unfortunately all I have is a dad bod, or rather a Father Figure
I could easily cosplay as Buddha.
Because we’ll.. I am a dad 😛
Both of my kids are tiny balls of fluff. lol
Torricelli is my son.
Fat Thor cosplay!
Look, I can’t do beautiful Norse god
I’m thinking more “unworthy man turned to stone”
Stones can’t move so I’ll stay home 😂
Lol, you could do a Medusa victim
That’s what I was referencing lol
Medusa looks like Wozalsky's girlfriend.
But Wozalky's girlfriend's snakes are great.
Noobmaster69 cosplay?? 😉
Lol
😵💫
This one is better
Cue the MrBeast video
This is so properlly, adequate, etc...
🤣 💯
Hehe
i kinda get how cool those gauges look on this to cosplay as cyberpunk
🙂
The circle of life.
My father receive this calendar every year from the "Doctors without Borders" ("Medicins sans flontieres").
They are very nice, they send magazines sometimes, etc...
Pretty nice.
How cool
My favorites are Charity Water, maybe Bill and Melinda Gates foundation and Save The Children.
But he still does not donate to neither of them.
I do not like when this happens. They have others Terminators on AP here in my location, but not this Terminator.
Ever thought about a VPN?
I'll see on Netflix again, maybe I typed the wrong name.
OK
what is the environmental impact (interested in both marginal and systemic) of running a tiny discord bot on a tiny $3.50/mo AWS VPS?
Probably very small
Smaller than running it on your own server for sure - I think.....
But don't quote me 😉
it's definitely smaller than running my own server
Assuming that it is smaller than running your own server I can't imagine it using more than a few hundred watts of electricity at a time, so let's say it uses 200W, then that's 4.8 kWh per day of electricity. From there the environmental impact would depend on where the datacenter sources its power from
I guess you could also add on a little extra power for cooling of the server but that would depend on the proportion of the server power that goes to cooling (and i don't know how it compares to home computers)
is that 200W attempted to prorate based on what percentage of the physical machine's resources are used by that small VPS?
I guess one would also ideally take into account the resource usage of maintenance / fleet management software that probably runs periodically on each VPS (probably runs more frequently than my discord bot sends messages...)
I think I'm ideally looking for a comparison to something non-computer, e.g. "it contributes as much to global warming as eating 8oz of beef per month, or driving a car 10 miles" or something like that
though in the beef case, there are also quite a lot of confounders / differences between marginal and systemic
Probably like driving a car 20-30 miles - so not bad
But then again - I'm not any expert
I doubt it will be very much, it will be consuming a very small amount of the total server.
Too many variables. But probably nowhere near 200W even
200W is what my gaming rig pulls when I run folding @ home so both the CPU and GPU are near 100% continuously. A Discord bot is gonna use far, far less. Assuming they're not losing money, that it costs $3.50 a month caps Amazon's power cost at that. I bet it's less, but let's use that as a bound. $0.19 / kWh, at most 18 kWh. Natural gas lists 0.91 lbs CO2/kWh - via https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 - so 18 * 0.91 = 16.38 lbs CO2 when we assume as an upper bound that Amazon is getting everything but power for free, and makes no profit, on that VPS.
The average passenger vehicle emits about 404 grams of CO2 per mile
16.38 lbs / 404 (g / mile) = 18.391 miles upper bound
As another bound, if you were to run it on a Raspberry Pi 4, and doing so maxed out all 4 cores all the time, it'd cost about 154 wH / day * 31 days = ~5 kWh / month. Running that through the same numbers, 5 * 0.91 = ~5 lbs CO2. 5 lbs / 404 (g / mile) = driving 5.6 miles @wooden schooner
Pi consumption via https://raspberrypi.stackexchange.com/questions/5033/how-much-energy-does-the-raspberry-pi-consume-in-a-day
Datacenter cooling probably about doubles that.
I'd be curious what the overall efficiency of the various cloud vendors is. I would guess Google would be in the lead.
If Apple doled put their server capacity to customers, based on my experience, they would be the most efficient energy wise
Most of their data centers are 100% green during the daytime hours. Unfortunately they require to be powered off the grid during the night
I did do a short stint at an Apple data center in Star Valley/Conover, North Carolina. They had just about 1 square mile of solar for daytime operations.
I wonder if they've largely abandoned X86 for more efficient CPUs (which would make sense, but wouldn't appeal to a segment of possible customers)
I wish my rigs were only 200W... but that's CPU wattage for me
I know at least from my short time they were still very much using x86 systems but they were getting more involved with Facebooks Open Hardware initiative
Which I learned from a data center tour at a Facebook facility that all their server hardware is open source
And it comes racked, stacked, and configured so all they have to do is roll it into place and plug it in.
Pretty neat. Facebook also has huge goals for renewables in their data center operations. From what I understand they were almost 100% at this one particular location for daytime ops
ARM is working its way into servers, along with other platforms... I have a feeling x86 will be around for a while. A mixed approach is probably what many will go for, 'cuz sometimes you still need that POWAH
So I'mma be doubling my main storage server's capacity :D
Almost
42% increase
For POWAH, Google is offering PowerPC servers too.
For an assortment of reasons, it seems to have largely left the console world (aside from Nintendo), but for heavy server use, it's still quite popular. The Power10 architecture was released recently and it's a beast (I think Google's current offerings are Power9).
I'm keeping an eye on MIPS, now that it's open, it might become more popular. Oracle seems to have bought Sun more for Java than Sparc, as they don't seem to be doing much with that architecture, which had previously been one of the major server choices.
MIPS is mixed instruction set processing?
No, it's pure RISC
What does Nintendo have with PowerPC? I thought the Switch was an ARM based chip
It could be Nintendo abandoned it after the Wii, I haven't really kept up with the console world.
I was using a PowerPC server last year for some experimentation I was doing with float128. Definitely not dead, just way less common.
Evidently. I didn't even know about Power10!
Wii U was sorta PowerPC -- the Wii was a "real" PowerPC processor, Wii U got a custom one blended with AMD and proprietary Nintendo stuff
Switch is ARM
So Nintendo made the switch from PowerPC to ARM
Interesting
Switch is Tegra, which is ARM based from Nvidia
I found a new computer I’m going to get! The Ben Eater 8B3C has a whopping 3 bytes of storage and 1 byte of memory!
lol
Lol Ben eater’s 8-bit CPU is a lot of fun
Hehe
I need to watch the rest of his videos
I need MOAR STORAGE! But thankfully I have moar coming
I wonder who in the world has the most personal storage capacity...
Lol, that doesn't count
thanks @vagrant sonnet for those very illuminating back-of-the-envelope calculations, and all for the discussion
Wow, that makes my first computer, maxed out with six 6810 128-byte SRAM chips, look like a beast.
lol
one thing I haven't seen mentioned btw is the possibility of greener energy at night when there is less demand. Does that not apply for data centers because they intentionally put them in places where there is less demand from residential?
They’ll often place themselves by hydro too
Since data centers have a relatively constant power draw (a LOT of power: about 3% of the total electricity generated in the US), the only way to optimize draw would be to store power during the night and use it during the day, and there aren't a lot of good ways to do so.
There's a lot of bitcoin mining done in Iceland, where there's cheap geothermal power and basically free cooling.
this sounds like a joke
the cooling is because the country name starts with "ice"?
Amusingly, that goes back to a clever bit of social engineering done by the Vikings long ago: they named the cold one "Greenland" and the less-cold one "Iceland".
wait, wouldn't the greenest power be from Greenland?
so what makes cooling free in iceland?
Iceland is warmer, but still cool
I'm assuming cooler ambient climate doesn't make much of a dent in the temperature of data centers under load...?
Depends on how low ambient is
And volume of air
If you can move a LOT of air, then it very well may
Even if ambient is only a couple degrees cooler
current ambient temperature of whatever google considers to be the exact point location of Iceland is 58F
ah hm... yeah I hadn't thought of that. If every cooling method ultimately relies on moving hot stuff outside, then I guess a few degrees outside could make a big difference
honestly I'm kind of surprised that facebook and apple are investing in green data centers. (It's great!)
what's their incentive? is it the conscience of individual execs?
Largely stockholders. Going green can be good in a lot of ways -- at that scale, there's the potential to lower energy costs, and there's no price you can put on the good will from the public if you stop contributing to pollution. Plus it adds stability because you don't need to rely on the grid maintained by someone else so much
wow, I totally didn't realize that "going green" could come out net positive on a time frame investors are interested in. That's great!
I suppose all the big companies have at least some of their own hardware design, and they have every incentive to make it energy-efficient
didn't realize though that using alternative energy sources could also be net positive
I like Masques Brownlee and him to give me tips on popular technology products.
MKBHD top notch
Yeah, things like solar have become cheap enough at scale that it can cost less to buy and operate and maintain a field of solar panels than it is to buy the same amount of energy from the grid. Depends on where and how much, but it's an option now
it's not just investors, customers are increasingly putting pressure on companies to do the right things for society
The "good will from the public" is the incentive for investors, they want people to be happy and keep buying product
the days of the Friedman Doctrine are numbered
(that a company's greatest responsibility is to increase shareholder returns)
I think it's just shifting from greedily cutting and stealing wherever possible to actually optimized business practices -- good business is good for people
my sense of general public awareness was that basically the public doesn't know what a data center is, and would either not care or be easy to deceive about how important data center energy cost is.
hopefully that's wrong!
A lot of people probably don't know what a datacenter actually is, but they know it's important and consumes power, and want less of that. Or more responsible power consumption [re:green] at least
Things are becoming more and more transparent in terms of operating costs, energy, etc., so I don't think a company can easily deceive their customers. Plus I think that's kinda illegal?
(Calculus) Why does a delta squared get ignored as it approaches 0?
I find that just…weird
Like why is it considered negligible, if the value will still exist in any case?
Like it doesn’t matter how small it is, it still exists somehow, right?
Basically, the idea is that if delta gets small, delta squared will get much, much smaller than that. So if the analysis proves that things approach a reasonable limit by looking at only delta, you're pretty much guaranteed that all higher-power terms will "come along for the ride" too.
Maths!
L’hopitals rule is great for proving this out too for certain equations where it isn’t quite obvious
From this line -- to which I'd answer "yes that's true, if you mean what I think you mean" -- it sounds like your question might ultimately be, "What do people even mean by 'approaches'? What's the bottomed-out definition that I can actually make concrete sense of rather than just wave my hands?" And I'd say the answer is something like: There is a whole edifice of mathematical machinery to answer that question. It does a great job, but takes a lot of investment to wrap one's head around, and many people in non-math fields find it a better use of their time to stick with slightly vague statements that don't quite hit the bottom-level definitions.
Mathematicians and theoreticians in mathy fields do also speak in vague terms, but it's usually grounded in a more precise idea of what their vague language means. I.e., they're at what Terry Tao refers to as stage 3 in this blog post https://terrytao.wordpress.com/career-advice/theres-more-to-mathematics-than-rigour-and-proofs/
I like to say his name, in brazillian accent saying L'Hopital's french name is kind of pretty.
Actually french language is so pretty that most of the names in french are beautiful.
It is impressive the amount of e-mails that I received about researchers that made citations to Terence Tao's works on Google Scholar.
Have you ever read any Lior Silberman and Terence Tao research (that they made together)?
Like analytic number theory papers?
Any work that they made together.
Bringing up an old thread, as I just tripped over a video showing the bell ringer still working after 176 years (video is from 2016, so it has been over 180 years now). https://www.youtube.com/watch?v=UtQGYz4f3YQ

On my list of "coolest things ever", very glad Tom covered that. I hope he'll check back in eventually
What about a very cheap project to make adults diapers have an humidity sensor to tell when the diapers are wet?
The problem is that the humidity sensor is so rigid.
The size is ok for the microcontroller. It must be protected because or the humidity.
It must be ok for a big and very rich company to make it very unexpensive.
*humidity
There are other sorts of sensors you could use to detect moisture that aren't as big. That type is really only meant for soil
What one do you suggest?
This might be better https://www.adafruit.com/product/4535
But if you're just trying to tell if the person wet themselves, all you need is to have two conductors and the liquid will close the circuit, can probably read directly from analogue pins
There are alarm buzzers for children to help them not wet the bed -- 9V battery, Piezo buzzer, and wires with snaps that go down in that area. When it gets wet, BZZZZZZ
No because it can be the two.
The two what?
The number two.
Oh, well, you can't detect that with a moisture sensor, unless it's... y'know... liquid number 2
I do not want to be funny really, I do not like to be funny.
I do not know any other way to say this.
Nothing that get out of our body is 0% humidity
It'll have liquid in it, but particularly for the plant style sensor, it's not enough to be detected -- there has to be liquid water between the legs of the sensor
Bet the plant style sensor detects in a solid ground.
Even for something like that HTS221 humidity sensor, being in the presence of waste probably won't be detectable
The sensor has to be in the dirt, you wouldn't want to get it in the number 2
Scientifically no difference.
You'd want to have it behind some of the diaper so you can pull it out and put it in a new diaper
This is not the whole idea.Cleaning takes time and discipline.
And the diapers are changed everyday.
Sometimes more than 3 times.
Diapers are meant to be disposable, you'd want to be able to quickly move the sensor over -- don't want the poor person sitting there without pants for several minutes while you clean a sensor
It is a prototype.
This is the pourpose. Each diaper with a circuit.
Disposable circuits.
Eventually we might be able to make sensors cheaply enough to be totally disposable, but we're a ways off from that. But not sure how you'd line a diaper to ensure it would make contact with solid waste
For detecting solid waste, I'd say the better option would be to go for some sort of stretch detector. Anchor it to the "wasitband" portion of the diaper, and have it get stretched "down" with the added weight of waste.
You could even have it be an external sort of thing - Something that the actual diaper goes inside of. At that point, it's just replace the diaper and put the sensor back on over top of it
When you get into the car there is a linear momentum added the sensor could beep.
You can account for such things, and it also depends on what type of stretch detector is used, as well.
Long-term stuff is more likely to be waste, while a short-duration thing that returns to "normal" is probably some transient thing like getting into a car or whatever
I'm not saying it's flawless, that's just where I'd start
If my father used a notebook it would beep.
But ok, it is an idea.
Sensors can be hard... But yeah, I just don't think any moisture sensor will work without sticking it into the waste
I hope you're not skerr'd of needles
I took Pfizer vacine against Covid yesterday.
Both my parents took AstraZeneca. I wanted to take AstraZeneca too. :/
I was signed up for J&J for about. A day. And then there was something with it so they took it out of use for a couple of weeks, so I ended up getting Pfizer.
Super pleased with how it went. The only needles I've really interacted with (that I can really remember) are dental ones and those suuuck. This? Nah. Bloop. Done.
Yeah, nice small needle
My reactions with Pfizer were so small, less than 4h of reaction(that I remember, I am saying 4h for safety for me it could be less than 2h) after more than 2 minutes after I take the vacine and it was so slight.
Same for me, I basically had a sore arm for a couple of days and that was about it.
My reaction to covid last November was incredibly mild
My dad felt like crap after getting the moderna one, but some of that was just other things being enhanced. My mom said she had practically no side effects from the J&J one.
I only lost my sense of smell for about 7 days
Me too!
I was fine other than that. So I imagine my overall vaccine reaction to be very small
But for me it was more than 7 days. It was so strange!
Even very strong smells like desinfectant I could not smell anything at all.
It was disappointing being able to taste food and coffee but not be able to smell it
Before university I remember reading a chemistry question telling the history of a brazillian woman that mixed desinfectant, bleach, detergent, and maybe others related for cleaning, but when she did it the different molecules reacted and produced a very strong gas, and after she inalate the gas she lost the sense of smell forever.
Chlorine gas
She’s lucky she survived
Since bleach is Sodium hypochlorite when it reaches with other detergents it can create chlorine gas. Most laundry detergents nowadays don’t contain reactants that would produce chlorine gas
But if you mix pinesol and bleach, that’ll do it.
Skeer different chemical reactions produce maybe different chemical elements, chlorine gas may be a nocive one, but there are other combinations of cleaning products that produces nocive gases, this woman mixed a lot of them.
I know this
But the most common reaction by product containing bleach is chlorine gas
This is a well known fact
The woman mixed a lot of cleaning products.
Mixing bleach and lye doesn’t produce dangerous gasses
We worry about these people here, they are called the people that obey common-sense knowledge
Actually I think all ONU's countries(the ones that respect ONU at least) worry about them.
Essentially what would have happened to that woman is she mixed chemicals that caused the bleach to break down into water, salt, and chlorine gas.
Non scientific "knowledged" people.
Bleach rarely breaks down differently
And this quality is what makes it a perfect catalyst for making chlorine dioxide
I worked for a company that used 20 degree muriatic acid (HCl) to make chlorine dioxide
Same thing
Muraitic acid is the industrial name for Sodium Hypochlorite
Muriatic acid here is chloridic acid.
And it is diferent than bleach's hipochloridic acid.
Muriaric acid is very corrosive.
Yes
It is not this, maybe.
Not true, bleach is corrosive in high enough concentration
I am telling about chemistry using the woman that was trying to clean the house better's situation
She did not have contact to industrial chemistry's special products
bleach in the US has the corrosive symbol on the bottle for household chlorine bleach. I would assume that means it's corrosive enough in household applications. it might be different overseas so i can't speak to that
i know different countries have different acceptable levels of dilution for household products
i've seen some miraculous things though concerning industrial bleach
one supervisor i worked with held a wad of chem pads on the gashed opening of a vat of bleach that was broken open by a fork lift
he could have easily died
walked away with but a few sores on his hands
I hope the company paid him compensation.
He got his paycheck and still had a job
My family has a lot of friends that received compesations from big companies about these accidents.
Because of the non-profit org my father works for.
It's a non-profit law company
He wasn’t the kind of person to go after companies for stuff so he just moved on
I hope he's happy anyways
He lost opportunies to win money.
he's one of the happiest people i know
mostly because he doesn't care much about money
Different people different personal's laws.
Maybe a lot of opportunities just with this single accident.
🤑
In Brazil the lawyer would use laws inside CLT to the client(your friend) get his money.
The creation of CLT was also influenciated by ONU for sure.
After the end of Second World War.
Will Adafruit's Discord be getting the Threads function??
Nothing to do with ONU or CLT 🙂
It's likely, but we're still hammering out the specifics on how they're going to be implemented.
I see. I figured that it was just a Discord auto-update function.
They do introduce some more moderation work, so we're not sure if we're going to allow them for every channel, or for every user.
We're also waiting to ensure that Dynobot (Our auto-mod) works with them.
Got it. I saw Dynobot in another channel, so I thought it was pretty cool that you created it 🙂
when I saw the "(Our auto-mod)" thing 😂
It would have been cool if we did, but that's not the case.
Yeah
My family knows 1 to +3 people who got rich of money doing it (millionaires in the currency of my country). Using CLT laws.
Wow. I think the whole suing system in the US is crazy, and that people are too touchy as to what they sue for.
Like I've seen someone get millions for user error driven problems in the workplace - SMH
US is a very right and mercyfull country with workers I believe. Probabilly you have similar laws with similar benefits or even better.
We do
And it is 🙂
Companies spend millions of dollars in the us to criticize and label lawsuits for injury and such.. and frivolous and meaningless. Most of them are well justified
This is just my life, no smell, only taste
I don't get the /tableflip function
On the note of "not every user", have y'all considered having some sort of role-based control on user actions? Some servers have a level system, so long-term users gain certain privileges
Yeah, I agree with most of them, but not all of them
(╯°□°)╯︵ ┻━┻
Oh haha
That's what I assumed was meant.
I see haha
The / functions still don't work
😡
It's never really struck us as being particularly necessary, and does add complexity to moderation in some cases.
Mmm, yeah... Moderation hard. This is why I avoid it these days XD
🤣
I'm just glad this place seems to be safe
I agree wholeheartedly
I'll let you in on a secret: It's not tirelessly. We do get tired. But that's why I love this moderation team. Any one of us can go "Hey, I'm not up to this right now, can someone handle it?" and it gets handled.
You've also probably noticed that the team is... significantly larger than many other servers' moderation teams. This is part of why.
Oh I know 🙂 I was more or less referring to your resolve to fight crime
👍 👍
Def one of the biggest mod teams I've seen. I've seen servers with about as many users but with only like, 4 admins and 10 mods total, but I think there's like 2-3 times that here? Lots and lots
I've seen some of those servers and they're crazy sometimes.
Oof - yeah
Horribly so DX one server I'm on has 55k users, the owner "moderates" [re: causes chaos], 3 admins, 8 mods, and it's just... complete chaos at any given moment. Half the mods don't show up most of the time, abuse is rampant, scams abound, and it's just not great
Like the Python server has only 5 admins and 7 mods
Yeah, that's. Not great. At all.
I love that here we have a good community, too. Our moderation team doesn't have to do a lot because you all are pretty good at, well, being pretty good
Some servers try to use mod bots to compensate, but that can end up going horribly wrong and banning innocent people
🙂
Yeah. Plus y'all will gently correct people instead of BANG banhammer when someone does a naughty
What's with all the people the server shows as online whose names are like, 0x8040, and [N1GS]Barbatio?
Bot mods are really good, but also really terrible sometimes too. Dyno's quite good at catching people trying to get around the filters - when Server Discovery was on, there was quite the creativity of ill-mannered folk. But Dyno also has a tendency to go "This is repetitive and therefor spam!" when it's just a code snippet.
That happened to me one time
People can set their names to whatever. There's so many people that just "lurk", and they're just fine.
It's why Dyno doesn't ban people, only mutes. It's a lot easier to undo a mute.
Some servers they'll have like 12 different mod bots and you could get caught up with like 4 of them hitting you for a thing, then telling a 5th bot you have 5 offenses, and then you get banned... bad systems
I've just never seen any messages from those people, and a third of them are just hexadecimal codes
I remember the days of IRC servers
They don't cause problems so honestly I'm not bothered.
Ahhh, IRC
I agree
I used to code up chat bots with games and whatnot
Like Texas Hold’em, a game of life, battle ship
Fun quote generators
🙂
Lurkers gonna lurk.... They're far more common on art-themed servers -- people literally just join to look at art, and never ever talk to anyone
Discord is IRC+
Circuit sculptures = art 🙂
IRC++
I lurked for like my first couple weeks here
Dinner time! See ya
LOL
Me too
I lurked. And made puns.
Tinkering with a Bluefruit board, I connected to it from the app, it detected that the firmware was out of date (0.6.7 of Sep 17, 2015) and updated it over the air, neat!
I still lurk
I remember that, I think!
That's the best part
I don't even remember why I came - I think it was for a Deep Dive 🤿
I've been here since March 31st and before - it was for a Deep Dive or Ask an Engineer - I think it was AAE, though
Yeah I like hanging out here
I just got my prepositional logic working in 5 hours much better
Does anyone here knows an electrical/electronics engineering fair like CES.
But for engineers.
CES are more like aimed to the population.
Actually I know there are a lot, but I know only small ones.
What kind of prepositional logic? Are you building a language parser that handles prepositional phrases?
What's a preposition again?
that is like those operation rooms
Ha, that's the other room with 6 monitors
most production-ready engines disable prepositions, too vulnerable to garden path attacks
what's that flat wooden slab you have under all your equipment?
My desk XD
I might be saying the wrong word I been up all night it’s tthe horn clause logic as oppose to predicate logic
If my mother saw this, someone would be in real trouble because of the organization. (No she would not make any trouble with you because you do not have to obey her laws or my father's laws.)
Lol, I make my own rules around here
Uhhhhh... Discord, are you high? I don't use a screen reader
Don't worry, it's probably just some malware using the screen-reader interface to scrape all your data. 😉
I am sending so many e-mails on my holidays.
Actually it feels I am not in a holiday.
(Charles Chaplin above for the ones that do not know him)
Ah crap... I downloaded and printed a PyBadge case, but didn't realize it needed screws
Print some screws?
I don't think that'll work, they're smol
If you're looking to buy smol screws, I get mine from RTL Fasteners or Bolt Depot.
I might be able to just glue it shut...
Probably quicker than waiting for parts to show up.
Yeah XD
If I keep doing this I'll have a study slump for sure it is worst than put the hands on fire.( it is an analogy, you should never play with fire, specially if you are a kid reading this)
I studied everyday during the semester, even on sundays.
Actually I didn't feel like finding glue so I set my hotend on my printer to 170 and used it to weld it shut, lol
... Actually, I am dumb, glue was right here
Oh well
Decided to forego the button stuff
Also, this has been going with 28 NeoPixels and the OLED for like... 14-16 hours? I'm impressed for an old 2200mAh cell
@delicate stream Purely on looks, I'll stick with this...
That doesn't look like a PyBadge 🤔
ODroid Go-Advance.
Interesting
Oof
At least it's free 😄
Lol
Free only counts if you can get it at all XD
Nothing is free!
In this case, you pay $0, and you get nothing!
lol
My soldering course tomorrow is "free" but the real cost is 7$ to take the bus
vs if I didn't go
Also I have to clean my space after use
I have never seen obsolete used as a verb before...
It's the participle of participle
Same
Ah, it's been a minute since I've rigorously studied grammar. I read a lot more when I was younger so I can generally tell when things are grammatically incorrect but I rarely could tell you exactly why
Although it still seems like obsoleted is almost never used from what i've seen
Mostly joking. One of the participles is in Latin
I know how to grammar, but I can't explain it
(presumably obsolete came to English as an adjective, regardless of its Latin origin. I am a silly word nerd)
All words are made up and nothing mattters
hey guys, do you think the macropad would provide a beginner a good entry into coding?
@sick marten It's a great little board, but it's a very specific use-case. The Circuit Playground Express or Circuit Playground Bluefruit offers a far better beginner experience, much more extensible.
You might want to get a CircuitPlayground Express -- it has a bunch of built-in sensors that you can play with without having wires or anything
And kattni beat me XD
I'll definitely check it out, I've had my eye on the macropad because i feel it's something I could use and integrate into my setup, but if the circuit playground express would help me learn code more then i may have to purchase both
Oh! If you have a use in mind for it, MacroPad is a great place to start. The CPX has far more options for getting to know electronics and programming in general though.
But if you can afford both, I recommend getting a CPX for sure.
yeah may have to do that and grab em both in one go since shipping is kinda costly
are there any kits or addons that give the CPX practical uses?
I like buying all the things at one time
CPX comes free with... a 200$ order, I think? That's another thing to consider if you end up with enough stuff in mind for an order.
Hmm. Good question. It really depends on what you have in mind as "practical uses". There are things that work with it, but on some level, it has a lot built in. There are definitely practical projects that use it, but for beginner purposes, it's meant to stand alone. Check out learn.adafruit.com and search for Circuit Playground Express to get some project ideas, and the guides will have hardware listed.
oh okay, awesome, i'm gonna grab both of those for now and then see where it takes me 🙂
thanks so much for the help!
Make sure you get the Express, not the "Classic". Classic is far less capable.
the soil moisture thing is cool, maybe i can stop killing succulents 🙂
Yeah! A simple project but a really great one!
Wish I had that type of disposable income left this month...
$200 is free shipping, $299 is a CP Express
Ugh yeah, I understand that entirely. It's a lot.
Ah thanks for the correction. Oops.
I recognized today that people with less money than me can be way more educated than me, more polite, more creative, more usefull to the society and the whole world, etc...
Nice discovery.
😦
I discovered today if I had 10MW of power I could run a Duga-like radar for the lulz
And be heard accross the world 😄
Even on other worlds
My father told me 10 years ago to not look at the neighboors with the telescope.
@sick marten Apologies for the incorrect info on order amounts. Doctor posted the correct situation.
Still better than looking at neighbors with a scope
Expensive addiction is expensive
A lot of people.
got into keebs over pandemic, now getting into this, i will never financially recover
Got into scopes over pandemic, now I have a pile of restored but obsolete scopes. I don't use them to look at the neighbors, however.
I would be simultaneously impressed and disgusted if you managed that
I just got a 1/2 gallon of southern sweet tea
