I need a screen shot of that!
idle iron
so like you see your friends where they are driving?
i think ill use it on trips with more then one vehical
covert spire
They blocked most of that, but you can share eta to friends
idle iron
darn
jaunty jetty
so if a bunch of waze users get stuck, other waze users get routed around, if waze users see cops, it tells other waze users about cops, if waze users tend to get in accidents at this intersection, it has a mode where you can have it exclude difficult intersections
covert spire
Yeap, live traffic jams get insta reported
It's more to me "I get to do making in GPS maps!"
jaunty jetty
there's a bunch of legal difficulties involved with apps that you're intended to use while driving; for one in almost every state amidst the united americas it is illegal for any portion of a vehicle to display an animation to the driver beyond the complexity of scrolling text on a radio display
covert spire
Wait, which states?
jaunty jetty
so showing the locations of your friends on the map as you drive could be seen as a road hazard and probably some municipality tried to sue them
covert spire
I see it as hazzard
idle iron
={ I chose liberty over security, how can we fix that?
jaunty jetty
not when your liberty kills other people because you drove your car through them
this is one of those places where regulation exists to protect bystanders
idle iron
what if you have a co pilot, like a passenger that does all the navigation... but we cant do that cause features are banned
covert spire
They can hold the phone & use it
Waze & Google has set up for that, no need for anything more than that.
In passenger seat, it's not visible to driver
jaunty jetty
features aren't generally /banned/ on phones, because it'd be really hard to do
it's much easier to regulate equipment installed onto the car
covert spire
Same as some states banned radar detectors
If you don't care about app UI, stand for traffic updating liberty, & would like to help other route better to destination. Waze is it.
idle iron
hmm im still a fan of liberty over security, the few bystanders that my die are just population control... lol Just Kidding i agree with what you guys are saying
covert spire
If you want lane guidance, a pita system for updating maps, which means maybe once every year or two something gets corrected, but still willing to load bunches of photos! Google Maps is for ya!
idle iron
i like street view for google maps, ive used it a few times to find stuff
covert spire
Both has SV
jaunty jetty
google maps is very workable, but given google owns waze, you'd think they could do a better job with traffic data
covert spire
Tho, I think Google has it in app
Google bought out Waze
Waze started independent
jaunty jetty
android street view is a separate app in the way that most of google's apps are built on the assumption that they'll all be present and can ignore the separation
and google maps has traffic, it's just not great
covert spire
The current reports of traffic is from Waze
jaunty jetty
really the worst thing I can say about google maps as navigator is sometimes it will decide there's a faster route, and declare onto you "He, push this button or I'm changing your route in 5 seconds, 3, 2, done, we're going this way now!"
covert spire
Tho, Google is trying to add in new system to use their own to resolve that
Yea, both do that
Sometimes irritating, sometimes it's helpful
jaunty jetty
I really need them to add a "do not at all consider changing the plan, just get me there the way we agreed on" option
idle iron
lol yeah, the "i dont care if i get stuck in traffic" button
covert spire
Yea, that plan was thrown out. Regardless of how many times I ignored nav
jaunty jetty
driving is hard for me, I need to stick with the plan
covert spire
Well, sometimes the traffic reports can be wrong, beceause of 10-15 minute server delay
idle iron
last week it helped be avoid completely stopped traffic on highway 101, so im all for it
jaunty jetty
I'm fine with stopped traffic
covert spire
If you live in So Cal, I absolutely stand by it.
jaunty jetty
I haven't ever driven on a freeway for 15 miles without stopping
covert spire
Although, I used Waze to get to destination that the locals that left me behind said "We know the fastest way there!"
Was behind like 5 minutes, beat them by 15 minutes
It taken me off of freeway
idle iron
im thinking its good to have around LA, the roads there give me anxiety
jaunty jetty
reading regulations... what's a multi-stage automobile?
is that like a multi-stage launch platform?
covert spire
Where?
jaunty jetty
I think they might mean multistage manufacturing of automobiles
section 571.141 Minimum Sound Requirements for Hybrid and Electric Vehicles
covert spire
That is what it seems to mean
idle iron
i want to make an auto mini hydro system like an aurogarden but better, with like peristaltic pumps that all you have to do is dump waste nutrients then add water and press button and it gives correct amount of nutrients and pH it for you
Id use GH 3 part nutrients so i think id need 5 pumps, 1 for each part of the nutrients and one for pH up and one for pH down
jaunty jetty
man a lot of this text is so excessively clear that I'm having trouble understanding it
S5.2.7 The identification of the following items need not appear to the driver to be perceptually upright:
(a) A horn control;
(b) Any control, telltale or indicator located on the steering wheel, when the steering wheel is positioned for the motor vehicle to travel in a direction other than straight forward; and
(c) Any rotating control that does not have an “off” position.```is there an experimental automobile class where you dont need to abide by all the regulations?
jaunty jetty
no, that's called private roads
vehicle regulations only apply to public roads
what is this measurement https://www.ecfr.gov/graphics/ec01au91.069.gif
idle iron
cars suck, i like airplanes... ultra light for the win
idle iron
what is with that stop sign???
the measurement is from corner to corner for the 450
not sure what the 150 is
jaunty jetty
that's not corner to corner though
jaunty jetty
if you drew a line between the two corners it would not be perpindicular to the dimension
covert spire
Yea, it's not angled correctly to the sign to be side to side or corner to corner
Also, given numbers, that's a small sign
idle iron
17.72 inch?
jaunty jetty
that 450 is nothing
if I take out that 15 degree constraint, the octogon becomes undefined
covert spire
Is it 150 per side?
jaunty jetty
the 150 is the text height
covert spire
Stroke of letters - 20 mm
jaunty jetty
you can measure regular polygons from point to point, the length of the sides, or the inscribed circle, but that 450mm is nothing
covert spire
Given width?
jaunty jetty
stroke length would be the thickness of the character
idle iron
wat is the 455?
idle iron
so 455 is diameter and 450 is corner to corner?
covert spire
No
idle iron
the 455 doesnt even touch the sign on the top left
idle iron
okay i dont understand that
jaunty jetty
so, these are the ways you can measure a regular polygon
idle iron
why wouldnt they have the 455 in the first pic instead of 450?
covert spire
That is the golden question!
jaunty jetty
only for n-gons where N is even does the dotted line through the middle cross the center, for odd sided gons the dotted line won't cross the center and you'll have three numbers
in the specification, the leads of the dimension intersect opposite corners, but are not tangent to the inscribed circle (D455 in that sketch)
covert spire
Which is why I said corner to corner is essentially diameter
jaunty jetty
because they aren't tangent and do intersect corners, the leads must be at an arbitrary angle, and thus we know the dimension is some random number that relates to the octogon's size via sine
covert spire
I have seen outside corner to corner used, tho I'm not a fan
idle iron
i need to learn geometry this doesn't make senses to me how does changing the angle lose 5mm?
covert spire
I wish numbermaniac was up
He'd get a kick out of this
Given a side is reduced from circle, making smaller sides
If you noticed how much less side to side measurement is.
jaunty jetty
so, because the dimension is at an arbitrary angle, what you're measuring is this
idle iron
geometry is magic.... https://scontent-sjc3-1.xx.fbcdn.net/v/t1.0-9/67677_167289126620405_438930_n.jpg?_nc_cat=102&_nc_ht=scontent-sjc3-1.xx&oh=c37ec4914ae5d9d890c84dbf3bc6b48a&oe=5C90052D
jaunty jetty
so here I've increased the inscribed circle diameter, the circle created by the point of all the corners, but the red lines are the same, it's a bigger octogon, therefore the angle of the red lines has changed, but the red line dimension is still 450
covert spire
Ah, so 465 mm is corner to corner!
jaunty jetty
we can actually vary the octogon arbitrarily between it's inscribed circle diameter being 450 and it's flat to flat width being 450
well, on an octogon, hexagon, etc
covert spire
Supposed to be octo this once!
jaunty jetty
the inscribed circle measurement remains true in this example for all gons greater than 2 while the point to point measure is incorrect for half of them
for a pentagon
now on the pentagon we don't have a flat flat number so the upper limit of how big a pentagon with the depicted measure being 450 can be is actually set by the distance between the point to point line and it's parallel line
setting the upper bound on that at an inscribed diameter of 765.5857mm, quite a stop sign (for a bus)
octogon can only go up to 482.7520mm, triangle would probably crush your car

with so little knowability about that processor, it may actually be a hardware limit, which would be so sad. At least software can be fixed

tender nimbus
@jaunty jetty Celerons are not good. ¢…¢
jaunty jetty
Celerons are an extremely broad range covering like 15 years and many acceptable devices
Chromebooks have been runnimg them for the whole time chromebooks existed, and they've been acceptable
20.5 years
starting at 266MHz single core and predating x86
modern celerons are core i CPUs with hyperthreading, clock boosting, and some virtualization disabled, and less L3 cache
that's perfectly respectable as long as the price is right
the problem is this laptab performs significantly below it's contemporaries that either it has a seriously bad processor or the software is a total mess. If the model number of the processor was known we could rule that out, but it's been obviously hidden in a way that combined with the performance problems, suggests the worst
for what it's worth, the newest generation celerons in the Coffee Lake architecture are all dual cores between 2.9GHz and 3.2GHz with UHD610 GPUs, that's a totally worthwhile chip for something like a chromebook
tender nimbus
Mmmm I see.
jaunty jetty
honestly for a device like this I'd rather have an i3 in the 1.xGHz range with turbo up to the high 2.x's it should be considerably more power efficient and as long as the device has appropriate hardware solutions like video decoders , 3.xGHz should be unnecessary to run ChromeOS and be very responsive. I think the Pixel Slate is available in an i3 but there also aren't details about that processor. i3 can only be so low spec, I wouldn't really be worried, but that's probably a 700$ laptab, 600$ is already kind of a lot for a low spec device even if it's ultra portable
for reference, this is the 2011 Macbook Air, running a 2010 i5 1.6GHz dual core, and I can tell you from experience it's still an extremely relevant laptop https://support.apple.com/kb/SP631?locale=en_US
it can run 3 displays, it can show 1440p60 video in real time while doing other things, it can render websites quickly, it can't play games that well but if you're buying an ultra-portable device that shouldn't be on the table
and it was early in apple's anti-repair designs, so it's fairly repairable
any students going into the winter semester who need a laptop and want to learn some laptop repair skills, there are a number of dubious MB airs for as low as 60$ on ebay https://www.ifixit.com/Device/MacBook_Air_11"_Mid_2011
ha, the main logic board, containing CPU, GPU, and RAM, is 126$, but if you had to replace all the core electronics with new parts you're looking at 450$ in parts, not counting the battery, keyboard, or screen and not shoping around. That's a pretty intense repair and you'd have a very good laptop for 510$ plus tax

Thinkpad doesn't come with an OSX license? I also haven't seen one for $510.

I dont get how do I only allow certain people to post Posts in my Blog
@jaunty jetty Any idea?
jaunty jetty
?
tender nimbus
Like if I have a DB of users how would allow only them to access the Create new Post webpage ?
jaunty jetty
that sounds like you're developing a custom CMS for your blog and I am not a web developer
tender nimbus
CMS ?
Oooof. Oh I see.
This is super frustrating TBH Cause I cant even figure out how would do I do it.
sweet mango
Happy Holidays everyone.
tender nimbus
Happy Holiday to you too man.
jaunty jetty
CMS design is not basic stuff
it combines webpage design, server infrastructure, database administration, and infosec
now if you just want to make a basic blog you can eliminate a lot of that by designing a templating engine that renders flat files, and then you just upload flat files, but a core problem with what you said at first is in order to have a DB of users you must first have a user login system, and that's also a giant bag of ravenous magma worms
tender nimbus
Mmmmm Thats the freaking point.
Like currently I configured the blog to do something like this:
Get all posts, specific post, authors directly from DB and use the template engine to render to the data into a fancy webpage.
For ONLY creating of new posts use some kind of login system cloud of unclarity
For creation and update of new Users use a Discord Bot and not a webpage
This has been really painful. I just dont get how do I like make the login system.
jaunty jetty
btw, just for a sense of scale, infosec, database administration, server infrastructure, and web design (in a broader sense than just webpage design) are all degree programs.
tender nimbus
😅
molten salmon
@tender nimbus do you know python?
jaunty jetty
unless you want to aim for one of those degree programs I suggest relying on the work of others, find an existing system that's being actively developed, opensource is a good idea. There will be many existing projects that are being actively worked on by people who know what they're doing
tender nimbus
If you are thinking what am I using for Backend then Its NodeJS
molten salmon
I think it would be a great language for you to learn for what you want... then things like this tutorial would be useful.. https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world
jaunty jetty
what I mean by degree program is, you can go to college for just that. You can't go to college for python, you can use python at college, but python is not something you get a degree in. Running servers good is
tender nimbus
@jaunty jetty Well I get you. But Meh most of the projects dont either have proper documentation or they lack an user authentication system or they use a prebuilt library for that purpose. I did find some YT Youtube videos but they are quite long (5 Hours) (And some are 30Mins but meh)
jaunty jetty
youtube is not going to be helpful for this kind of project
it might look like it do, but it ain't
molten salmon
ps. section 5 of that tutorial is user login system
tender nimbus
@molten salmon Well I could use Python. But Mmm the point of this project is get better at NodeJS. BTW Python is next on my list of todos after learning JS quite properly.
@jaunty jetty Ugh. True. Its filled of some Garbage Vids.
jaunty jetty
one cheap workaround to having a workable user login system is leveraging google/linkedin/twitter/facebook/etc, who all offer that as a service so you just have to hand the user off and accept the result
videos are just an extremely terrible way to convey information about programming
tender nimbus
I really love the Angular Firebase Implementation Vids But Meh Ill have learn that then.

if you're talking high concept like computerphile it works pretty good, but as soon as you need to be talking in terms of specific code, any non-text format has massive drawbacks

tender nimbus
Mmmm Absolutely. Agreed. But The point is the only way around this user authentication would be using some kind of cookies cloud of unclarity But what if peeps use VPN
Computerphile?
jaunty jetty
it's a youtube channel
this way google handles all of the user account stuff, you just trust what google says to determine if you'll show things to a browser
tender nimbus
Is it free ? 🤔
jaunty jetty
probably
google benefits from websites leveraging google user accounts, because you have to have a google user account to log into the website
websites benefit from leveraging google user accounts because then they never have to touch user account data (infosec) and are incapable of liability for anything what happens to the data
tender nimbus
True ^^
jaunty jetty
users benefit from websites leveraging google accounts because then they don't need another account
tender nimbus
No need of maintaining User data and even if your DB gets hacked you dont suffer much 😂
jaunty jetty
I for one don't do many things (visualstudio) because I just don't want to deal with having an account at another place
your DB in particular would only contain blog posts and a list of google account IDs with permissions
tender nimbus
^^^
🙃 👌
Need to now figure out how it works.
Ugh. I got homeowork to do too. 😭
Thanks for the info man
🙏
jaunty jetty
btw, if you're doing this because you think the skill will be useful to getting a job, you should be using nginx with mongoDB and node.JS on a virtualmachine
tender nimbus
Nginx ?
jaunty jetty
request comes into the VM, hits NGINX, NGINX forwards it to a node.JS script which figures out what should be sent in reply based on data from the request and data in mongoDB
it's important to learn NGINX because it's commonly used as an ingress node in cloud hosting applications, being familiar with it is valuable
Node.JS is good but I'm mostly including it because it fits well in this paradigm
tender nimbus
Mmmmm The requests can go directly to the nodejs script right?
jaunty jetty
MongoDB is a noSQL database server and that also works better with clouds
I'm not sure what you're asking
tender nimbus
Like Generally when I run it on a machine I dont need NGINX. So why would I use it ?
Like why do we need it?
jaunty jetty
node.js doesn't matter
nginx is a skill that will raise your salary by multiple thousands of dollars
jaunty jetty
and make sure you're doing all this in a VM. Bonus points if it's in a docker container
spice moss
tender nimbus
Ooooh So I my doubt was something like when we have a NodeJS web Server why would we want an another web server. Seems like You do some kind of layering and Nginx takes away some of the load.
And Docker container ?
Well TBH I was just thinking of using Heroku. Seems like I might have to buy a VM next year.
jaunty jetty
jaunty jetty
you put the OS in a VM, you put software in a container, then you can instantiate both as necessary for scaling, and it's all protected so if one software gets hacked there's no access to others, or if one software crashes it doesn't crash the rest
tender nimbus
I see I see.
jaunty jetty
like say tuesday your blog is getting 20 visitors daily and you can get by with one instance of NGINX and one instance of node.js, but thursday some big newspaper linked your blog and now you have 120k visitors hourly, you can A, spin up more NGINX and node.JS on the existing VM to exploit more of the system resources, or, spin up more VMs to get access to more system resources
this is the power of clouds, the ability to scale with demand
those VMs aren't free, you only want as many as necessary
tender nimbus
So Nginx and VMs allows me to Scale ?
jaunty jetty
yea, it's of course more complicated than that, but yea
jaunty jetty
so, you have to design for scale at all levels, starting with your domain
tender nimbus
TBH I was just gonna buy a domain like sjdhsjushdyajaysustausudthwu7362737282hyhe7ej282u.com
jaunty jetty
nonono, we're talking about something much different than what your domain is
jaunty jetty
you can have regional records for your domain, so depending on where people are they'll see you as existing at different places, and you can set up sets of domain records so as people make requests the DNS gives them the next in the set, this is first level round robin and regional load balancing
jaunty jetty
so each one of those records points at an NGINX (load balance nodes), which points at like 20 NGINX (ingress nodes), which then distribute requests among various instances of node.js and whatever else you need to run
say there's a user, and they instruct their browser to display your website
step 1, where's your website
browser sends a DNS request for yoursite.blog and a DNS server gets that request
step 2, you have regional records, let's say the DNS has cached records for your domain, so it has the records appropriate for it's region.
it picks a record, and sends it to the user's browser
it picks a different record every time
say you've got 5 records for that region, 20% of the traffic will go to each
step 3, with the DNS reply, the browser now makes the request to that record to get the webpage, and the first thing it hits is NGINX
tender nimbus
So like I can create several instances with NGINX so that my Traffic gets distributed in short ?
jaunty jetty
NGINX does a lot of things, if you want to scale well the first NGINX points to a bunch of other NGINX, all the first one does is spread the traffic around, it can do that really fast and you put that one on a very fast computer that only does this
the second layer of NGINX then care about the request, and they send it to the thing that's actually going to resolve the request, which in some cases will just mean grabbing a file from the SAN and sending it back, request done
tender nimbus
And the other NGINX Slow computers then handle the requests ?
jaunty jetty
the other NGINX are dealing with a small enough load that they don't specifically need very fast computers, and they can share the machine with other software
you can have multiple VMs on one machine, and multiple containers in one VM
tender nimbus
Mmmm Well I wouldn't need that on a website with only 10 visitors per day right?
jaunty jetty
designing for scale remember, you can't just will this into existence when you need it, it has to be built to have the ability. But yea you'll only have one NGINX to start with
keep in mind that when you're doing things to learn skills, it's very likely that the benefit of those skills is not applicable to your civilian needs, but you profit from learning them
tender nimbus
Ugh. I guess I'll have to first master the basics then move onto this complicated stuff.
jaunty jetty
so get a VM, go with somewhere like linode or digital ocean, hiroku is going to hold your hand too much and you won't learn basic stuff
then learn how to set up docker containers on the VM, even if you don't need them, you need to know
jaunty jetty
don't we all....
tender nimbus
Yeah OFC. But some peeps have rich uncles. 😅
jaunty jetty
well once you figure that out, linode advertises on a lot of podcasts, and each one has a coupon code for 20$. the basic VM is 5$ so that's 4 months, and you have to pay for a month to use it, so that's 5 months for 5$. It'll be plenty of VM
tender nimbus
Mmmmm
Well coupons generally apply when you spent more money than the coupon right?
jaunty jetty
no?
tender nimbus
Mmmm Oh Noice.
jaunty jetty
that's not a truth of the universe
coupons work exactly the way they say they do, and I used this one
tender nimbus
😅 I assumed as google does it that way on Playstore.
jaunty jetty
so get a VM, install some linux, I recommend CentOS it's like redhat but free. Learn how to set it up, how to install stuff, how to configure the firewall and set up services. Then comes docker, then comes NGINX and node.js
tender nimbus
Ugh. I guess I'll have to start either with Heroku then get some money and then move onto a VM (or do some hardwork on Quora)
Mmmm I see I see.
jaunty jetty
you don't need to be a linux master now, but that will be part of the job later
also, you can totally run a linux VM on windows
just on your desktop
or laptop
or mac
it's way overcomplicated to connect stuff on your home network to the internet, but you can touch it and do stuff now for free
tender nimbus
Well that means I'll have to keep my desktop on 24×7
And Linux stuff is Exciting and interesting
jaunty jetty
protip: you don't try stuff on the live server, you run an offline instance where you make it work and then you move that to the live server.
I don't expect you to do that but it's good practice to have a local VM set up the same as you webserver so you can mess with stuff up close
tender nimbus
Yup. Makes sense
jaunty jetty
you could if you want get a raspberry pi 0 W but because that's ARM... 5? it's going to be different than a VM running x86-64
just start doing stuff, it's important to do stuff
jaunty jetty
you can download centos now, and download some virtual machine software now and have a virtual machine running in like an hour or two
for free

btw, rule #1, servers are headless, terminal access only
when I run the graphical desktop on my pi zero it's at like 70% utilization constantly, but in headless mode it's only like 0.4% ever, graphical desktops are wasteful and get in the way. You need to learn how to run linux from the terminal
tender nimbus
Woah Thats a lot of difference
Thats like super cool
The only thing I am always scared about Raspberry Pis are that they might freeze or get corrupt
😬
jaunty jetty
plan
- Get some linux
- use it
- try stuff
- get a server maybe (optional)
- break stuff, go back to 1
- figure out docker
- figure out nginx
- figure out node.js
- make a web thing show up on a different computer
step 5 is very important
tender nimbus
LOL I am expert at that
jaunty jetty
you're not going to get anywhere if you treat your learning tools as sacred, they're disposable, break things, learn how you broke it, learn how to not do that again
tender nimbus
I thought I would go like 8 7 and 6
jaunty jetty
even if you destroy a pi 3, that's like 35$, that's not so bad unless you're getting evicted for not paying bills. But it's really hard to destroy a pi without physical mistreatment
tender nimbus
Well I can't break things that are hard on my pocket
jaunty jetty
if you just ruin the installation, you start over, nothing lost but time
jaunty jetty
you reinstall and start over
jaunty jetty
and then you learn that periodically you should back up the memory card so that instead of reinstalling and starting over from 0, you can re-image the memory card with a backup and just be set back to then
see, learning from mistakes
super secret: actual servers get messed up too
jaunty jetty
big companies have their servers set up so they can boot off the network, configure themselves from scratch, and join the cloud
tender nimbus
jaunty jetty
if you try you can usually find a pi zero W for 5$, an SD card for 8$, then you need an appropriate power supply and you can get by with nothing else
tender nimbus
I have only 10% of that in my pocket. Might have to ask my parents as a Birthday Gift (March)
jaunty jetty
the pi zero W has Wifi, so you set up the flash card to know how to get on the wifi already, and you log in with an SSH client, like putty
tender nimbus
Wooooah Just like my phone's Command Line?
Thats Noice.
I really want to design a HAT for that thing
jaunty jetty
hard to say, no common phone OS have native support for command lines, and no aftermarket command lines are consistent. you might need to get an SSH app
tender nimbus
You know a HAT with Full size USB Connectors, maybe VGA Type Connector
I got Termux
jaunty jetty
that sounds difficult to make
I know USB hub hats exist
not sure what you'd need to make VGA come out of the GPIO header
tender nimbus
Yeah thats the hard part
Might just make a HMDI to VGA Converter
But Whatever I guess for now. Dont have it in hand to say anything.
jaunty jetty
just to throw it out there, if you did make that hat, people would give you money for it
tender nimbus
Why ?
jaunty jetty
why?
jaunty jetty
for it
tender nimbus
Wouldn't they just the PCB Files and fab it?
jaunty jetty
why would you buy an arduino when you could just fab it
why would you buy a macbook when you could just fab it
you wouldn't download a car
tender nimbus
But that would mean I would have to Fab it myself and solder the parts and then ship it right?
jaunty jetty
definitely for the prototypes but there are board houses for production runs
Arduino doesn't hand solder every uno
tender nimbus
😬
But Investment would be required at first
Ooooof I generally either lack skills or money
jaunty jetty
once you've got a proof of concept there's kickstarter
I'm just going to ignore lacking skills because you need to get the skills even if you just make one for yourself
tender nimbus
Mmmm Yeah 🤔
jaunty jetty
options exist, do stuff and see
tender nimbus
But Like for the proof itself I would need lots of investment of money and time
Yup
First Plan: Get a source of income
jaunty jetty
although you might want to go easy on yourself and make the VGA adapter into a full size pi hat, which will be compatible with the pi zero GPIO but the pi 3 is significantly more powerful than the pi zero so it'll have a better time running a graphical desktop
tender nimbus
True.
The reason why I wanted the VGA Connector is cause my Monitor has VGA Connector
jaunty jetty
the majority of all servers in industry use VGA connectors
VGA is sturdier physically, and massively simpler in application, so it's pretty rare to have any fatal problems with VGA
jaunty jetty
even if you have a VGA cable with like three pins missing you'll still get a readable video stream as long as it's not both VHOLD and HHOLD or multiple ground pins
tender nimbus
They have those crazy screws on their connectors taht get screwed in to the other connector
jaunty jetty
jaunty jetty
if you lose both H-sync and V-sync, the video won't be stable on the monitor; but some good monitors of a certain age are able to replicate the syncs independently
tender nimbus
Mmmm I see
jaunty jetty
if you lose RGND, GGND, and BGND, then none of your colors will work
if you lose any one or two you'll be missing just those colors, which is still readable
tender nimbus
Soooo many GND and pins
jaunty jetty
then there are 4 pins that do literally nothing, losing those will do literally nothing
jaunty jetty
but then in the server itself, the hardware that supports the VGA is super robust and simple. It's extremely rare for a server to lose all of it's VGA capacity because of a hardware problem
no, this is a standard connector and they just didn't need them all
jaunty jetty
that's too vague
tender nimbus
Vague?
jaunty jetty
RCA connectors are used for a lot of different things
tender nimbus
Well they just have two terminals right?
jaunty jetty
composite video, component video, channel audio, digital audio, probably others
RCA cables are up to 2 conductors, one of which is the shield and should only be used for ground
tender nimbus
The TV we have has those connectors
There were a lot of wierd connectors invented TBH
jaunty jetty
so composite video isn't great because it puts all the elements of the video feed into a single analog signal, it's pretty lossy, pretty low resolution, doesn't react well to high framerates (30FPS+), is easy to interfere with, etc
component video uses separate conductors for each component, so it can transmit more data per time, which gives it less loss and a better resolution cap, otherwise the same problems
jaunty jetty
as far as I can tell in 5 minutes component video has the same signal structure as composite, but each conductor only has to transmit one channel of image data
tender nimbus
Mmmm I see 🤔
BTW Do you know of any good alternate solutions for Rasp 0 W ?
This one looks Noice.
jaunty jetty
what do you mean solutions?
I buy mine at a local store that usually has them for 5$, but as far as a different thing; if your PC is broken, try to get a PC that isn't? it'll cost a lot more
tender nimbus
I mean do you know of any other alternatives to Raspberry Pi Zeros
Nd I'll get my PC Anyway
jaunty jetty
there's Orange Pi, Banana Pi, BeagleBone, all of which have their ups and downs
raspberry pi has far more market penetration than anybody else, so there's much better software support
tender nimbus
The Latte pandas are cool but not cheap
Soooo Can we install linux directly on these boards ?
Or we need specific distros meant only for em?
jaunty jetty
you need a distribution of linux compiled for the version of ARM your board runs at minimum
so you can't run CentOS on a pi zero because pi zeros use an older version of ARM than pi 3
tender nimbus
🤦
Then Raspbian?
Or Something else?
Running without the GUI is really getting me interested TBH
jaunty jetty
Raspian I think si the only 'real' option for pi zeros, but if you get a pi 3 there are more options
tender nimbus
Ugh. I see more money = better options
BTW Check this out!
TBH That costs as much as a 775 Pc 🤔
jaunty jetty
so that celeron board you linked uses this processor https://ark.intel.com/products/78866/Intel-Celeron-Processor-J1800-1M-Cache-up-to-2-58-GHz-
seems adequate but the iGPU is weird and it's from 2013, so this would make for a bad desktop unless you put a GPU on it, and there's really no good choices in cheap GPUs
I don't know these moneys
tender nimbus
Oooof Thats INR
jaunty jetty
right but how much is it worth
what's the cost of 10 bigmacs
how much is a gallon of milk
jaunty jetty
in money
tender nimbus
In Litres how much is 1 Gallon?
jaunty jetty
a gallon of liters
tender nimbus
BTW As I mentioned earlier 1 USD = 73 INR
jaunty jetty
direct numeric conversion doesn't suggest buying power
how much is typical for renting a small one bedroom apartment
tender nimbus
Oooof Wait Lemme calculate
1 Gallon = 4.5 Lts = 22 × 4.5
Yup thats 100 INR
For 1 Gallon of Milk = 100INR = 1.4 USD
jaunty jetty
and 10 bigmacs?
tender nimbus
How much is one BigMac ?
jaunty jetty
how much is ten bigmacs
jaunty jetty
and how much is typical rent?
tender nimbus
2BHK for 124 USD Monthly
jaunty jetty
BHK?
jaunty jetty
so milk is fairly cheap, mcdonalds is slightly expensive, and housing makes me cry, mmmmmmkay
I pay 700$ for 1 bedroom, 2~3$ for a gallon, and about 32$ for 10 bigmacs
tender nimbus
Mmmm Cry???
Oooof I see I see
Anyway seriously man we can get like 775 PC at that price of the last deal
jaunty jetty
isn't LGA775 dead?
tender nimbus
It is
But who cares
Its cheap and noice
I still have my old 775 PC sadly its mobo dead
jaunty jetty
if you buy a PC with a celeron processor, it's pretty easy for those to be decent, so put more consideration into the graphics they have. There are some graphics that are decent, and some that are useless, it will have a large impact on the system's overall quality
you're probably not going to enjoy having a celeron before about 2016
tender nimbus
Mmmm Might just get instead a Optiplex
If I had the money
Or an old xeon server instead
jaunty jetty
optiplex is a dell prebuilt branding not a processor
tender nimbus
I know I know
But they do come with decent i5 2nd Gen and i3 3rd Gen Processors
Which are quite nice.
jaunty jetty
the iGPU thing applies to i3s and i5s also, they can have decent built in graphics, but they don't always
if you have a useless iGPU you'll have to buy a graphics card, and decent graphics cards are much more expensive
tender nimbus
Well We dont wanna run GPU Intensive things right?
Or else we can just put in a 1050ti
Or Something slower
jaunty jetty
we're talking about a different category of good
tender nimbus
Oooof
jaunty jetty
and also we're talking about your new PC
tender nimbus
Mmmm I was talking about old PC
jaunty jetty

yes the choice is great. Look around on google which is the most used one. You think to do some wearable projects? Surprise yout mom with led stuff. There are some examples on adafruit, check it out. Look at the Flora and Circuit Playground Express too then.
Or the arduino in different types and shapes. Cool stuff anyway.
But the RP+ is also a very good one and you can do more stuff too
so many choices and less time todo things. That's the issue when you are older 😉

flint jungle
don't know because i will not use RP+'s but i think its possible. ask google RP+ and nodeJS

because java abstracts away a lot of the hardware
the hardware for the VGA

it's like how COM ports are relatively difficult on java, because COM ports don't exist in the JVM, so you have to interface with some native code that can touch them (which I'm pretty sure is part of a standard library but still)

My friend posted something on Facebook about sound frequencies and how our current tones are pretty much just flat. I was wondering if anyone has ever used 432hz instead of 440hz for A? does it sound better? also i found this and was going to use only these frequencies and hear for a difference if any.
jaunty jetty
how does one beta test a server?
jaunty jetty
but bots are the worst...
tender nimbus
🙄
jaunty jetty
frequency wise, there's a whole lot of cultural association for why we use the numbers we do, they do sound different and you can get an app from your phone to hear them but in the end flat or sharp is artistic
there's also the whole thing of multiple frequencies together for various effects
you can also get an app for your phone that will tell you what frequencies he's playing, but your speakers probably aren't tuned correctly so the exact value isn't reputible
for an inspection of the cultural history behind 440Hz, http://reasonablysound.com/2014/11/13/a440/

Using latest Raspbian Stretch Lite (Kernel 4.14) but no driver is present when I do lsmod or lsusb and only links I can find online require kernel rebuilding even though CP210x was supposed to have been included in the kernel since 3.6 😦

You guys might want to add some kind of verification. You know like reacting on a message to have access over other channels or like having some kind of level system where people only get access to texting on channels after some time. You know this would prevent against Raids happening here.
jaunty jetty
I tend to agree but it's hardly simple. Any kind of limiting factor is going to have collateral damage, users who didn't join the community because of the factor. The server caters to a lot of children and people who speak english as a second language who may not understand how to operate the system. Then there's the people who don't want to deal with it or are offended by it. They exist even if you don't hold their opinions.
if the server is going to keep growing, it will become targeted even if only ambiently by high availability of links for bots to find
there's also the problem of how to design the system, given that many users do and all users should block DMs from randos, so you must expect that server bots cannot DM people and design for that.
it'd be nice if discord integrated the feature from Slack where server bots are able to post messages into channels that only specific users can see
it basically allows for in channel bot UI for single user interactions, it's great, you can have buttons and stuff
tender nimbus
Aaah That feature would be nice.
The Single user interaction thing. I guess a similar thing can be even approached on Discord.
And Ugh Bots are not only limited to Bot accounts sadly. Peeps can even use User accounts with Bots.
And Mmmm I see. Oooof.
jaunty jetty
slack's server integration model is also a good solution
bots don't just exist, they have to be integrations added to the server by an admin, so you can't use the API unless it's an integration, and you can't just put an integration on a server. Any kind of bot would therefore have to be software interacting with a client and that makes it harder

So Yesterday I went to a Science Exhibit and there were some pretty cool projects over there. You know most of the projects were made of using PIC Microcontrollers. They had things Smart Solar Panels (You know they turn 360° based on where the sun is), Smart Traffic Lights (They switch according to the density of the traffic), Intruder Checker, and ATM Breaker Alarm and Fire prevention system
They also made a 2D Plotter and a F Type racing car of their 2018s Batch. All these project were made by students of the College
jaunty jetty
F Type? Jaguar?
360 degree freedom seems wasteful for a sun tracker, unless it's going to be mounted on a thing that moves, maybe a sailboat, that sounds kinda neat
at the equator on a mountain you're going to have slightly over 180 degrees of sky arc per day, and a few degrees of procession arc over the year. Up here in detroit you'll have far less than 180 degrees per day but a few times more procession arc
side note, this looks like a fun build https://cdn.instructables.com/FSP/5E9T/FR123NBE/FSP5E9TFR123NBE.LARGE.jpg

Rearranging the things around the cabinets. Although with more drawers, the contents will get rearranged as well. E.g. all the feathers won't have to share a drawer. My bench will have to be nudges a couple inches, which means the corner of the rrom on the other end of it will need to be cleaned out and organized differently. My tool board has to be flipped to be vertical (there's a window throwing a monkey wrench into my plans), which means a different system of hooks. etc. etc.

why can't an n channel mosfet be used to intercept power?
jaunty jetty
project idea: a box you can plug a USB keyboard or wireless keyboard dongle into, and the box plugs into a computer, the box then passes the keystrokes to the computer but when you hit a certain chord on the keyboard the box starts encrypting the keystrokes. Then you have a plugin for your browser or whatever that is paired to the box using TOTP or something, so when you activate the plugin and enter encryption mode, the plugin can decrypt your keystrokes; so they get from the box to the browser or whatever securely
you could even use it with say SSH clients, and have the server configured to decrypt, so your keystrokes are encrypted from the box to your server
any M0 board should be able to do it, use the native USB controller on one end and set up a USB SERCOM to host the keyboard
M4 has better crypto?
it might be worth using SERCOMs for both USB links, to prevent malicious software from flashing

Idea, a matched daughterboard for the CPX that has the same set of neopixels but pointing the opposite direction
I like the idea of making a ZPM, and the CPX could handle a few things, but I need light in two directions
It'd be a tough casting though
plain cedar
Would using neopixel rings work for that ZPM design? A project with CPX + neopixel ++ https://learn.adafruit.com/neopixel-led-harness-bra/overview
jaunty jetty
It would but it doesnt match the CPX's ring so I'd have to figure out how to match them, and you cant just mount the ring to the CPX
Alternatively I could use two rings and a not-CPX but then I lose the CPX's other features
plain cedar
You could use two rings, the CPX, and not the CPX leds? We are talking StarGate ZPM, yes? It's a pretty big lampy looking thing.
jaunty jetty
Thats starting to be a lot of stuff inside that shouldnt be
plain cedar
Oh, so not doing BLE, Wifi, and 5G at the same time in this? 😃
jaunty jetty
Nah. The ZPM is fairly translucent and all this is going to be visible. The ideal for me is a stack of the CPXand matched light ring with the shortest risers that will fit a LiPo cell between them. Some lightguide design in the casting will help to obscure the stack then I can fit a usb port hidden under a magnetic cover at the opaque center on the flat end
Then I want to use very small wires and conductive paint to make regions touch sensitive
Bonus cool would be building a ZPM socket stand charger
jaunty jetty
looking for good shots in the show to base the design off, somebody's auctioning a 'non-working' ZPM replica
I should hope it's non-working
jaunty jetty
looking at adapting the neopixel ring circuit to a CPX format board, I know I complain about some stuff sometimes, but this is the positions of the 'pin' holes on the CPX, reduced via symmetry to only one instance of each number
edit: positioning mistake, in the dimensions under the geometry, 0.8375 should be next to 0.8400, not 0.8925. The divation is 2.5 mil not like 60
on the right the top 3 and bottom 3 are totally symmetrical so the whole set is defined with 7 numbers, because the middle pin (on both sides) is on 0,x
now, it's close, but even the right side as good as it is does not fall on an arc, some of the pins are exactly 1mil off
it's a bit worse if I center the arc on the origin, so this arc is ancored on the top pin hole and concentric with the origin, they'd be slightly more inline if it was a 3 point arc shared by the top, bottom, and middle pins
(units are inch because catia doesn't do mils and I don't know how to make it)
one of the reasons I love parametric modelling so much is that I can just tell catia that these things should be symmetric and it makes that happen, Eagle involves a lot of going into menues, calculating coordinates, it's less fun than I like but the software is good in other areas
last note, by the board file, the OD of the circular portion of the PCB is 1.00040342. I don't generally consider dimensions smaller than a tenth (of a thou)
jaunty jetty
ok one more thing, there's this one hole on the left, that has the same horizontal offset as it's opposing pin, but has a different vertical offset, so it's real close, if only it were 2.5mil higher, it'd be symmetric, but instead it's the most interesting pin on the board
a sane person may ask "but why?"
why of course, the correct rotation of every pin (except that catia won't measure past 180 degrees in 2D so the ones along the bottom need to have 180 degrees added

@jaunty jetty what are you using to create these? Cadia? And I agree with you, Eagle’s UX when it comes to setting up things like this involves a lot of menu digging and interface pecking
jaunty jetty
CATIA yea
I haven't used fusion 360, but my understanding is the overall principle of parametric design is the same there
now the tricky part is I have this but nothing actually exists at the crosshairs for me to position it, so I have to figure out a process of transforms to shift and rotate these via the command line to get them where they need to go
even if I center the circle on the origin, the pad isn't attached to the circle and won't move relative to the circle center
jaunty jetty
oh boy, eagle is terrrible for automation
jaunty jetty
and then I discovered that eagle kinda weirdly ignores the position of the mark when rotating things, based on the grid. it doesn't shift to a grid position, it just kinda does whatever, so those 3 angled pads are garbage
I have to set the grid really small and do it again
abstract violet
@jaunty jetty I dislike the way grids work in Eagle 😬 not gonna elaborate.
jaunty jetty
should have gotten a picture with the board OD shown, it's really obvious now that the rotations were all wonky before
why the grid is considered in command lines where I have given explicit coordinates is baffling, but I'm under the impression a lot of Eagle is 30 years old, and they're working on it, so I shall stick with it
jaunty jetty
I have not been working on this the whole time... but some labels and the base component will be done
it's way too late but I noticed the tab sticking out is waaay too long, turns out it's 30 mils longer than I had intended; it'll still get cut off so it's fine
the process btw is
MARK (# #)
COPY (>0 0) (R0 0)
// stop and redo the selection to only contain the new copy
ROTATE =R# (C>R0 0)```
where mark's #s are the coordinates and rotate's # is the orientationin the parenthesis > means "we're dealing with a group", R means relative, not sure what C means but you need it, and in rotate, the angle has to be in the format R#, and adding = at the front makes it absolute, it's relative by default and this R means Angle... cuz

So in other news we were at mcD's on the weekend and set our phones down on the table. And they all read some NFC tags. Me being me went let's see if we can write to them. And sure enough none of the tags built into the table were locked. So now when someone sets there phone unlocked on that table it'll open Pablo the flamingo
Apparently this is a known issue of they meant to implement an ordering system with the tag's but never got around to it

All of the new McDonald's. One tag per seat. So in the booths we found 4; on the tables 20
jaunty jetty
only 4 tags? what is that going to contribute to the game?
karmic kite
I mean 512kb can do a lot
But the idea was they give you a coaster and could find where you sit down
jaunty jetty
but the games
no android phone is going to allow executables on an NFC tag, so you need the android app and the tags just open the games; if the tags were then a factor of the game then sure but if it's just a physical token to make kids demand they be taken to mcdonalds, that's advertising to children and falls under some laws
also they've already got tents for the ordering station, they don't need an active component for finding people to deliver food
https://fortunedotcom.files.wordpress.com/2016/11/mcdonalds0403.jpg the red things on the left of the station, you enter the number of the tent you pick up as part of the ordering process, then you put that on your table, and mcdonalds aren't that big so they can just walk the floor to find you
having a map marking the location of the customer to deliver the food to won't actually be any faster than just go'n'find'em, but it will cost tens of thousands of dollars for every location to impliment, and thousands of dollars per year, plus multiple laborhours daily in service of the coasters
the numbered tents are just plastic
karmic kite
Not sure what game your refering to but I'll find the article explaining what it was supposed to be
Ah I see. Madbodger found a different thing for it
Browsing Reddit and other sites it seems some places do have them programmed for table number and location
jaunty jetty
there doesn't exist a possible workflow where any system could convey table position effectively to staff such that the processing time to see, integrate, and route based on said data would perform half as well as walking a standard route to just find them by tent
the secret here is that tacobell is the smart fast food place, they do most of the process engineering work and sell it to the others, mcdonalds isn't used to having thoughts
maybe if it's robots
is mcdonalds gonna mcrobot fast food? if they do they better drop prices by 70%

idle iron
i kept wondering why my iphone 5s seemed to be so hot in summer time in Fresno, CA
Operating ambient temperature: 32° to 95° F (0° to 35° C) Nonoperating temperature: -4° to 113° F (-20° to 45° C)
its over 95F nearly everyday in summer
jaunty jetty
I'm not sure how to interpret this
idle iron
like it overheats easy in summer, i had issues with pokemon go where i had to take breaks and stuff
jaunty jetty
sounds like you need a heatsink
the 5S has a nice boxy design, if you can get ahold of some heatsink stock and find a hydrocutter nearby, a 2D profile would be nearly finished, then you just need to file the sharp parts
idle iron
even then ambient temp is still over, dont think a heatsink will work
jaunty jetty
the ambient it can survive is established based on it's capacity to dissipate, if you improve it's capacity to dissipate then it can operate at higher ambients
jaunty jetty
it's actually like five layers of curves and one of them is relative temperature
the further case temp is from ambient the more heat will transfer per area, ignoring conductivity factors, per time. if ambient is equal to or higher than case, heat will not leave the phone, and as ambient approaches case the rate reduces. The peltier might work but cryocooling electronics is complicated and dangerous and you'll need a very large battery (also a heatsink)
the case isn't able to get that hot because you are expected to hold the phone and if it burned you, you'd be mad, so the temp delta with ambient = 95F is pretty poor
idle iron
i think the peltier heatsink and fan would work nicely
jaunty jetty
you'll need a heatsink on the peltier that can dissipate twice the wattage of the peltier but sure
they work as a heat pump, they don't just eliminate the heat
idle iron
yeah i read about them a while back they take heat from one side and move it to other side
jaunty jetty
and the other side also gets the waste heat of the energy consumed by the peltier
I don't think you'll need a particularly high wattage to keep an iphone cool, so you shouldn't need that big of a heatsink, if you have a 3D printer you could integrate one of those copper nub grid heatsinks so it's flush with the outside, and in the thickness include the battery
this style but the size of your peltier https://ae01.alicdn.com/kf/HTB1HJ_sRXXXXXbfXFXXq6xXFXXXw/40-26mm-Copper-Heatsink-4-0mm-thick-for-Laird-THERMAL-PAD-mSATA-NGFF-5030-msata3-0.jpg
also you can order thermal pads pretty easily to mate all this together
there's a bunch of options, even graphite which is cool, but in this application the give of a 1.5mm bit of rubber will help fit everything tight even if the surfaces aren't perfect https://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=thermal pad
and just to throw it out there if you wanted to go full passive, vapor chamber heat pipes are a thing that can be purchased, even flattened ones, stick a few to the back of the phone with thermal pads, thermal glue them to some low profile heatsinks to get a lot of surface area, build a case around it, I think it'd be more than enough
honestly plating the back in heatpipes alone is going to do a lot to move heat away from the hot places, but put in a bit more effort and maybe you've got a business
tender nimbus
Lets just make a custom heatsink for it. Like the whole back of the phone made of thin copper fins from top to bottom with about a centimeter of height.
jaunty jetty
Thats fine but it will be wasteful, heat isnt produced along the case, most of the heatsink is a long conductive distance from the heat sources
Heat pipes allow thermal energy to travel effectively, so the heat from where the CPU is can make use of more heatsink area
tender nimbus
I didnt mention I am gonna stick the Fin stack on top of the case. I said It'll be the case itself.
jaunty jetty
the case of the phone
the outsidiest part of the phone is the case
looking at some teardowns, the iphone 5S is not built for this, the A7 is not thermally coupled with any surface and is on a PCB facing the screen
if you're holding the phone as you would to use it, the A7 is at the right edge immediately up from the SIM tray, facing the screen. That's where you need to put the heatsink
it's under this farada shroud
the shroud doesn't seem to be coupled to the processor it's just EMI protection, and the shroud isn't coupled to the screen because that would cause localized color distortion in short time
cooling the case will still help to keep the interior temperature lower but I think this calls for a peltier
this seems like the best place to put it
late fulcrum
Somehow I'm reminded of the Klingon communicators in one of the Star Trek movies: the Federation ones were sleek and smooth, but the Klingon ones had chunky heatsinks.

I don't recall who's building Blackberry phones these days (Blackberry stopped making their own hardware after the Priv).
The craziest PCB shapes I've seen tend to be in old HP calculators and modern digital cameras: they'd use flexible ones in nutty shapes, folded into a complex 3D conformation almost like a protein.

OSH is getting foldable boards
they're not purple and OSH is sad about it
ooo they're ready http://blog.oshpark.com/2018/12/23/flex-pcb-orders-are-now-shipping/
keep in mind flex PCBs have a lot of design constraints, it won't flex across a component for one, and they're not meant to be 'living', meaning they're meant to be flexed into a shape and then remain in that shape forever, not be re-flexed a large number of times
like, I really don't see why this is on a flex at all, with all these components the possible flex lines are nearly non-existant http://blog.oshpark.com/2018/12/27/flexible-pcb-customer-project/
jaunty jetty
they're also three times more expensive
abstract violet
Looks like it was used to mod existing hardware, neat!
jaunty jetty
sure but it was glued into an enclosure that appears at least to have loads of space, so the small difference in thickness between the standard PCB and the flex PCB would not matter
it just cost a lot more
thin canopy
I have a number of projects where ribbon cables were used to connect a main board to a satellite board (usually a front and/or rear panel) that could benefit from a flex PCB. Most of these use enclosures that resemble cubes, not modern stylishly flat ones. 😉 With some planning, a flex PCB could simplify point-to-point wiring and perhaps make it easier to design for removable components like batteries. We'll see. My next guitar pedal -esque design will likely include one.
jaunty jetty
there are absolutely uses for flex PCB, but that project is only more expensive for it
the camera couldn't be what it is without flex PCBs

late fulcrum
Good idea. The old vacuum tube Tektronix scopes did great with massive overloads (I inadvertently put about 9kV into a low-voltage input once and the scope was fine). The modern ones have some protection circuitry, but more protection outboard is a good idea when dealing with those sorts of situations.

Any professional makers have a website or portfolio I could check out? My colleague and I have finally decided to form a public contractor partnership with a name and online presence and everything and we could use some reference material. Our work is very whimsical (props, escape rooms, experiential/novelty marketing), and our name and portfolio content reflects that, but of course we want to be taken seriously as people who have experience doing this professionally and deserve to be paid as such. Some general advice on walking the line between eccentric art engineers and sleek professionals would also be much appreciated.
