I've tried to go portrait many times, but I can't deal with the whole LCD viewing angle thing. All the ones I've tried (including ones meant to be switchable to portrait mode) are optimized to give consistent colors across the long axis but not the short one, so my eyes get two different colors/brightnesses when staring at the screen.

modern monitors are substantially better but that's still true

I just got a package from Amazon. A personal item...the internal product packaging was torn open, and lazily swapped with a different item.
I contacted them, and they were like -shrug shoulders- oh well, we'll replace it for you. Doesn't matter you pay for Prime, etc. Take the delay of the product on the chin.
One of the many reasons I like Adafruit in comparison so much. They make any problem right -- and I'm sure they look into issues when they happen so they don't happen again.
dusty citrus
Amazon seemed to change their delivery strategy fairly recently; packages began arriving through the Ghost Office, in rather unpredictable ways.
It used to be UPS who delivered Amazon goodies with free shipping over 25 bux.
There was no strategy to circumvent that I could find, which meant if I ordered multiple items they arrived on multiple days (often 7 days apart).
Amazon's just getting too weird, and I'm not into that. ;)
That's one Visionary who .. isn't. Or has lost control. Or something.
.oO( .. he ain't no Elon Musk .. )

amazon doesnt ship anything.
there are no amazon delivery trucks.
amazon uses regular delivery companies like everyone else.
if something arrived broken, you ask amazon for a replacement, or you go after the delivery people and hope that amazon used insurance on their delivery.

actually, i think amazon got into the delivery game.
maybe just for things coming from their warehouse if you are close enough, but with some areas offering same day delivery I think they had to
proven olive
Yeah, AMZL is 'Amazon Logistics' but they go direct from warehouse and are treated/paid pretty poorly. Which is reflected by their terrible reputation
late fulcrum
I have a bunch of friends who are authors or run small publishing houses, so my dislike of amazon goes way back, as they've been mistreating those people all along. Much happier with AdaFruit. I've ordered a bunch of stuff from them over the years, and only two things have ever gone wrong (one missing package, and a couple of duff Piranha LEDs), they made them both right with friendliness and efficiency.
dusty citrus
I ordered around 11:30 pm EDT (same TZ as Adafruit is) .. on Thursday. Used John Park's STROBE discount code for his show that day.
Shipped Friday -- generally they are done near the noon hour, sometimes eleven in the morning.
Arrived Saturday -- at 4:30 p.m. I was counting on Monday, so this threw me off.
On the other hand -- I have my loot and have tested some of it, already (at 11:00 pm EDT).
jaunty jetty
what are you talking about, AMZL is great, they reliably deliver packages within a quarter mile of my house, at an arbitrary time and date that I have no way of expecting
dusty citrus
We get handoffs to the Ghost Office, that's our new Amazon delivery service here.
jaunty jetty
I don't know what a ghost office is but that's basically AMZL, they move it inside amazon's supply chain until it's close enough to give to a local courier that hates you

The Ghost Office delivers the ground mail. It's run by the gubbernment.

that would be annoying as all get out. having to scale the mouse movement so that you don't need 6' of desk just to get to each side, but not so much that you can still have some "dexterity".
granite portal
as for the mouse scaling issues, i have a G600 mouse and it has a third mouse button, and i have it set to scale my DPI. so by default I'm at 1000DPI, then when i use the third mouse button, it goes down to 200DPI. probably really good for such a large screen real estate.
tame saddle
i have a RedDragon, 3200dpi max. the only time i currently hit the dpi button is a few instances in games. but, i can see how it would make things easier. though, i would probably just bunny hop in "normal use". 😄

I don't have a schematic handy, but it's pretty much like an ordinary 7400 NAND gate, but the input transistor has 8 emitters instead of two. https://www.electrical4u.com/wp-content/uploads/2013/08/ttl-nand-gate.gif
I was amused to find out an 8-input NAND gate contained only 4 transistors. It may be the fewest transistors of any TTL chip (although tied with the 74133 13-input NAND gate). If there were an open collector version, it would have only 3 transistors!
I suspect that is why this 74S30 includes a transistor with 13 emitters, but only 8 of them are used: they probably use the same circuitry in the 74S133 but all the emitters are used. I'll admit I wish I'd found this web site before I went to the trouble of taking my own die pictures. https://project5474.org/index.php?title=54S30_TI_8140
Granted, I didn't go to a lot of trouble to decap that one: it was a ceramic case, those pop right open.

Ok, this is a really offtopic post. A few years ago, I stumbled upon a digital art tutorial site (much like Lynda, udemy, etc) that was geared almost entirely at professionals.
They had only a handful of tutorials at the time -- around a dozen. But man, they looked nice. Things like animation, cinematic backgrounds, digital painting, etc.
They also had a heavily peer-reviewed & instructor reviewed tier -- for a little bit more, you could actually interact with the instructor during "office hours". And I remember they sometimes live-streamed classes on Twitch (to draw you into the paid classes).
Anyone here come across something like this? I've been searching for a few hours now, and I can't seem to recall it or find it in my bookmarks.
....and I just found it, on a google search for "art tutorial class price animation" on the fourth page. It's LearnSquared.
Ugh. Nothing more frustrating knowing you saw something but have no idea where...and can't find it.

There's also manga I follow about working out effectively, dietary consideration, parentage, healthy relationships, pro gaming, veteranary first aid, linguistics, and being an inventor, all of which feature this undercurrent of clearly trying to influence me towards a happier and more successful life within the scope of a certain life skill.

if I had a laser cutter I could get big sheets of double sided adhesive film, put them on things, use the laser to destroy the tape in some places, blow a bunch of carbon powder at the remaining, and have graphene PCBs
late fulcrum
Or just use the laser to burn carbon tracks in things?
jaunty jetty
it'd probably be hard to control thickness if you're just burning the surface directly, which will mean resistance and length are less reliable
also I'm not sure that would form graphene
late fulcrum
I bought a cheap laser cutter from China, fully expecting that it wouldn't really work out of the box, so I treat it as more of a kit than a finished appliance. Unfortunately, it has degenerated into yak shaving, as I decided to replace the optics and add air assist, which changes the mounting dimensions, so I need a new head bracket. Now I'm trying to decide whether to finish the CNC milling machine and make a new head bracket or get the 3D printer working and just print one.
I've already replaced the controller with an EiBot board, as the controller it came with is simply not likely to work in my setup.

It's a good example of optimizing effort to where it's needed. The CO2 laser tube is a beautiful piece of workmanship, because it has to be to work. The mounts are shimmed with wadded-up bits of cardboard, and the base is a somewhat rusty piece of sheet metal.
It didn't even work when it showed up, but I was able to track down the problem fairly quickly when I took the cover off the laser power supply. The AC connector wasn't even plugged in! It was a locking connector, so it hadn't just "fallen off" in transit, either. Their claim of testing every unit before shipping didn't really hold up. However, once I popped the connector into place, it fired right up and worked.

I have my very first Debian 9 installation near completion.
I think this is the first time I guessed correctly on all the files needed for a hard-disk based installation (booting from GRuB).
Mainly the correct .iso -- I usually grab the wrong one and have to retry with another one.
In xterm, If you
$ cat - | xsel -bi
and then middle-click (or Shift+Insert)
.. followed with a CTRL+D
.. it puts your pasted text where it can be then used in windowed applications (with CTRL+V to paste).
$ cat /boot/grub/grub.cfg | snippet
menuentry 'Debian 9 Installer - Dell Optiplex - sda1 - Jul 2018' {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos1'
legacy_kernel '/Debian.d/vmlinuz' 'quiet'
legacy_initrd '/Debian.d/initrd.gz'
}
$ ls -la /mnt/sda1 | egrep iso
-rw-r--r-- 1 nis nis 305135616 Jul 14 07:12 debian-9.5.0-amd64-netinst.iso
drwx------ 3 nis nis 4096 Jul 22 19:25 Debian.d
That's all it took to install Debian 9 on a machine that already had GRuB installed.
late fulcrum
What is snippet?
dusty citrus
that's just shorthand for egrep and what I needed to capture that text.
$ cat grub.cfg | head -247 | tail -12
is about what it took.
late fulcrum
Ah, got it.
dusty citrus
Unrelated: there's a good plugin for firefox-esr that lets you use any font you like for its menus.
Every time I bring up a new machine it's a big struggle to put things back where I had them before.
I still can't middle-click. I have to use Shift+Insert (had middle-click working in Debian 8).
That xsel -bi is new to me. It's a useful work-around (beats retyping when that's the best alternative).
I don't even have to write a buffer to disk to use it.

any'all ever been conscious of netduino, perhaps in such a way that you may be cognizant of the hurdles of compiling their .net based platform for maybe an M4 express
the netduino go runs on a STM32F405RGT6
the go has 5 0.1uF and 3 10uF filter capacitors, that seems excessive, must be pretty fragile
the N3 wifi uses STM32F427VIT6, these are cortex M4 chips with 2MB of flash, what's the difference between ATSAMD and STM?
keep in mind it's entirely likely I have no idea what I'm talking about
late fulcrum
They're offerings from different manufacturers. While they're both Cortex M4 cores, they'll have different peripherals, pinouts, resources, etc.
As AdaFruit points out, the ATSAMD51J20A is roughly equivalent to a STM32F405RGT6, but the STM is a little faster, while the SAM has more RAM.
ARM holdings has an interesting business model: they don't make chips themselves, but license the IP to various other companies that build the cores into their own offerings.
Like Atmel (at least before they were acquired by Microchip), they're a "fabless" vendor.
jaunty jetty
so architecturally netduino can probably run on an M4 feather/etc, but it probably needs most of the pins ..... resetup
late fulcrum
Right, as well as some software adaptation. It looks to me like the main difference is that STM chip comes with an external memory controller (I'm guessing the board has some additional RAM which uses this).
jaunty jetty
there is a storage register thing of some sort, M74HC595TTR I think
late fulcrum
I was perusing the SAMD51 data sheet in detail yesterday, to figure out how hard it would be to use the built-in high speed SDHC controller to add large amounts of storage. It turns out it uses the same pins as the QSPI port used to talk to the flash chip, so that's not practical. Naturally it can still talk to SDHC via SPI, but not as fast.
I'd be surprised if a heavyweight interface like a memory controller was being used to talk to a simple shift register chip.
jaunty jetty
there's a fun concept on the netduino boards and I believe the Fez where there's a bunch of JTAG sockets with a uniform set of pins set up as mini headers to support accessories, I might look into making a feather board that impliments a similar system
late fulcrum
The TI "LaunchPad" boards also have their own accessory connection. I was pleasantly surprised when my eInk breakout board was compatible, I just plugged it on there and it worked.
jaunty jetty
the Fez Spider, not an actual Fez main board
I think this would need some pretty serious IO expansion on a feather, so I'll make it a bird instead of a wing, the header will be either 8 or 10 pins with VCC, GND, SPI, at least one analog pin, and then 3~5 other things
if I stick with native analog pins then I can do 5 headers

one advantage of this is at any time you can pause the VM and duplicate it as a backup

Virtual Machines -- oh it's nice running a hypervisor on a bare metal -- ESXi stand-alone. But unless you have a strong home wired connection (1gb is a minimum, 10gb is ideal)....using it for a daily driver desktop would leave you feel lacking in experience.
The official term for that is VDI - virtual desktop infrastructure.
a nice way to get your feet wet is to download VirtualBox (free) for your host OS (what you're currently running on your machine) -- and play around with it.
jaunty jetty
laptops don't typically have huge hard drives these days, and you don't need to do it daily, also it can be done locally so 1gb/s is feasible
grave crest
The industry standard is VMWare
jaunty jetty
there's several free/cheap linuxed based hypervisor suites that are suitable for VDI
it's made for NAS but you can do anything with it http://www.freenas.org/
grave crest
I will say, I am mostly unfamiliar with the free/low-cost solutions regarding VDI and virtualization (aside from VirtualBox as that's the "big dog" in the free arena). Most of my experience is around VMWare's offerings
jaunty jetty
tame saddle
@grave crest Yeah, VirtualBox+Vagrant is what I currently run on the desktop. Will probably just replicate that for the next couple weeks while I'm out with the lappie. lappie is an i5-8250u, 8GB DDR4, and 256GB SSD. My desktop only has 8GB DDR3...so the VM should be fine. Will probably work the dual boot after I get back.
grave crest
@tame saddle Not a bad setup -- for most VM needs, the heaviest lifter is ram. And just sheer amounts of it.
That's not to say that CPU and storage isn't important (it really is). But hypervisor architectures have gotten very good at thin provisioning storage and CPU usage.
Thin provisioning, for those unfamiliar, is when you tell it "hey, I need 20gb of storage for the VM -- but it only uses what it actually needs -- like 8.7gb." It can use UP TO the 20gb, the VM "thinks" it has the full 20gb, but your storage is only used 8.7gb in this case."
So you can put another VM's storage in the same place -- "oversubscribe" the same physical storage so to speak.
But you might be asking: "What happens when BOTH VMs need 20gb and there isn't enough space?" Well, it breaks. Thin provisioning, like anything with the moniker "virtual" in front of it, is a "lie".
Anywho -- RAM is the most variable resource, and the greatest bottleneck for performance in a VM. CPU balancing is pretty decent as long as you have a good one, and storage you plan in advance. But RAM? It fluctuates. More = better.
@tame saddle Check in your computer's bios if there is an option for Intel's Virtualization Technology (VT-X), which greatly improves virtualization performance.
late fulcrum
You might look at Xen, which doesn't get a lot of press, but it's pretty solid (used in a lot of industrial deployments). I always found VirtualBox to be a bit hacky and brittle.

as long as you charge them in parallel it'll be fine, the powerboost might not be up to charging two at once and then it'll be slow, each cell will get roughly half of the current provided and they'll automatically level between the set
if you put them in series then serious hazards can result
sour olive
I tried fixing the micro USB charger port, but bridged the VCC to the unused data pins, then panicked that I was going to have voltage leaking and overheating things and blow up our installer so I tried fixing that and took off the pads.
But as far as an "obscure attachment", I supposed I meant as far as power/charging breakout boards go
Or I suck at Google.
jaunty jetty
they are individually 100% unique
because they're all slapped together out of parts on hand
you could follow the traces from the pads that came off to some place elsewhere you could attach a wire to replace the trace
sour olive
That was my plan at the moment, but in case something goes wrong I was looking for a "I failed, but we don't need to spend another $120 to replace this after they refused the RMA under warranty" contingency
That was my first ever USB port bypass, it's disgusting to look at, but it works.
Goes into DFU and writes to memory.
I was super bored and had a very fat soldering iron and nothing to do

Oh, it's just a pro nano with a single WS2812B attached.

D&D question, are all skeletal warriors the bones of previous humans resurrected by necromantic magics or could some be original skeletons that were never bound by flesh
proven olive
@jaunty jetty In 5e, the target of the animate dead spell, which creates skeletons, is a corpse or a pile of bones. Source of bones is not specified
frozen shore
Quite the change in subject there
jaunty jetty
it happens
proven olive
Indeed.
jaunty jetty
so in 5e all of the spells require an explicit corpse, you can't just summon a bunch of skeletons to crawl up from the ground on the assertion that people have died all over, but there's also skeletons in dungeons and whatnot that weren't summoned by a necromancer, they're more along the lines of ghosts that just occur based on negative energies and horrible events
the skeletons are considered undead, but especially in places like the underdark this requires a consistent supply of skeletons to be animated, even if it's happening ambiently
other kinds of monsters just kind of happen, some by population tactics and others seemingly 'cuz', surely there's enough magic around that bones could also just happen
let's bring this back to radio
if a person from some arbitrary country in europe came to america and died in a dungeon, and then eventually their skeleton animated, the skeleton is not the same personhood as the person that previously inhabited it, so is that Skeleton an American, and could they get a radio license?
they were 'born' on american soil

oddball question, do any of you draw on paper, using colored things other then pens?
I like the Sharpie Stylo or BIC Intensity lines of no-bleed fine tip felt tip pen-markers, but I need a blue that is visually distinct from black and purple
currently I'm working with black, red, pink, and green because they're more distinct
proven olive
@jaunty jetty what are you doing with them?
jaunty jetty
general sketching, ideas, messing around
also btw, the BIC Intensity actually bleed quite a lot
proven olive
I know of Copic watercolor markers but they are fancy high end things, so probably not what you are looking for
late fulcrum
A Flair Ultrafine makes a nice blue line. Micron has some nice offerings too. And of you can fill a Rapidograph with any ink you like.
jaunty jetty
those look Flairs look pretty good, I'll have to find a small pack to test, given these BICs that won't bleed definitely bled through three pages
late fulcrum
I tried Pilot Razerpoints too, but I didn't like the feel of them as much as the Flairs.
The Sharpies make a nice line and come in a rainbow of colors, but bleed right through a few sheets.
jaunty jetty
the sharpie stylos have been really good for me, but a 4 pack is 10$ and the blue looks really dark
vestal phoenix
Work up your technique, used dashed lines, dotted lines, dash-dot lines, zigzag, double or triple fine lines, etc. Good luck.

I was doing a calligraphy project a while back on some "laid bond" paper with a lot of surface texture, and most of my pens left gaps. The Rapidograph did a beautiful job with it.

It's ... different. Normally, I use a fountain pin with an appropriate nib, but I was going for a particular artistic effect, and tried the technical pen, which worked nicely.

Trust me dude, you are plenty smart enough to operate them. It just depends on the time you have and the access.
@jaunty jetty If you are looking to do anything with ink, I highly recommend trying out a fountain pen. I use a pilot metropolitan as my EDC, and I sketch constantly with it. The lines are super expressive and if you go for a medium nib, you can get wonderfully wide and dynamic lines. It also takes nearly no effort to make them write. I grabbed a pen and a bottle of ink for 16 bucks, and I have not once regretted the decision.

so how do you feel qualified enough to convince other people that they should employ you
grave crest
I work in an IT field where things change drastically every 6 months. So my thoughts below may not represent others experiences...
-Understand the culture of the company you're applying for. And recognize when that might not be a good fit for you.
-Know everything you put into your resume. Seriously, if you say you're fluent in French -- better be ready to carry on the rest of the interview en Françias, s'il vous plaît.
-Do your homework for the company and position you're applying for. If Company C makes Widgets, you best know the market, competitors, strengths, and growth areas of Widgets.
-Tech changes constantly. Know the basics. Have a solid foundation, so it makes their job easier getting you up to speed on their specific practices and technologies.
-Take an interviewing & resume writing class. I don't mean a 2hr online course, I mean multiple sessions with peer and professional review. Trust me, this will pay dividends.
-Speaking of Resumes -- this document should be hand-tailored for each position you apply to. And it should be perfect. No errors. Consistent formatting. One page + cover letter, unless you have decades of position specific experiences.
In terms of feeling "qualified", nothing speaks more to me than experience. Internships, personal projects, a "home lab" if you're in the IT work.
An example: someone who spins up ESXi for fun on their own time to learn about virtualization speaks VOLUMES to me more than any A+ certification.
jaunty jetty
A+ is so broadly irrelevant....
grave crest
Exactly. Most certifications honestly just tell me you're good at taking tests.
I want to see that you know how to get your hands dirty.
jaunty jetty
it's a direct user support certification that people treat as saying you're good at running servers
grave crest
If you're a developer, show me a portfolio of projects. Doesn't even matter how "simple" they are -- sometimes the best tools are simple ones that fit a specific need. That's the truest definition of "value".
Have a GitHub (or equivalent) account? Any collaborative work with others? No code is written in a vacuum.
So, that's a pretty broad stroke of general interviewing advice that can be applied pretty much anywhere.
What I've found worked best personally for me:
-have collaborative projects you can talk about [successes + failures]
-tinker on your own
-read & research prolifically
-own your own domain. Simple thing, but no one wants to see an @gmail address. FirstName@FirstNameLastName.com earns sincere respect.
[that last one about the email? pretty much got me my current job. They noticed and asked about how I did it, the process, the reasoning why....the self-drive, the desire for a professional appearance, etc.]
jaunty jetty
