@OliverSalzburg I was thinking about turning it into a PS script. Partially as an exercise, and partially because there are situations where PS can be executed but full exes can't.

A: A cell phone company talking about the dangers of texting — irony or not?

I wouldn't consider that irony. Here's a comparison that may illustrate the difference: If Bob, a representative of AT&T, tells you not to text and drive, that isn't ironic. It's actually pretty responsible. If Bob tells you not to text and drive, and then, while driving away from the presentat...

I'm so tempted to comment "Don't text and drive!"

Psycogeek

the Q would get a downvote here, there seems to be some assumption that the phone company created the mess to begin with :-)

I setup my phone to speak all the texting, that and handsfree, I can recieve text while still concentrating on driving itself. Trying to text even with Speech to text methods (that exist) still not going to cut it.
It is really easy to text and drive, if it wasnt for them Other people :-) driving too.

Bob

@Psycogeek And all those darn buildings next to the roads.

Psycogeek

this is california , nobody is dumb enough to put a building that close to the road. they got like 3-4 people a year in the "area" out of about 120,000 who drive through a business from the Parking Lot :-)

sheet the problem isnt toyotas throttle control, it'a you damn foot :-)

speaking of feet and gas pedals, originally the law here was you could NOT drive with bare feet, which i though was rediculous. People would toss on some kind of temporary shoe like "flip Flops" and it gets all stuck up down there.

So now the law is you CAN drive with bare feet, but not flip flops.

Dang Excel! I was working with .CSV files formatting and after saving them, realized that formatting is gone next time I tried to open them.

I have 10 .CSV file and wonder if I should "Save As" all of them through Excel in .XLSX format or use some batch converter to make job fast? However, formatting integrity remains question.

@Psycogeek Are you good in raw materials? Knowledgeable about stainless steel vs. zinc alloy quality and durability?

Psycogeek

only for my own purposes and needs.

Boris_yo

Okay, what is more durable and valuable?

1. Stainless steel
2. Zinc Alloy
3. Aluminum

Psycogeek

would be cool to have a stainless steel fence instead of zinc plated iron, bet that would cost a bundle. once water gets under a zinc coating thing as easily go to heck, stainless steel is forever. Has to qualify as a better invention than sliced bread.

aluminum can be more brittle/tensile wheras zinc iron and steel seem to be able to be shaped at room temperatures without becomming fractured internally.

alum is always way lighter, at least of any variety i have played with.

Boris_yo

08:45

@Psycogeek So stainless steel is mixed from metals but zinc alloy is only plating for metal like iron? And how can water get through zinc plating?

Psycogeek

much of the zinc stuff is just zinc coating over cheap iron, so it will last time.

Boris_yo

@Psycogeek In this case manufacturing garlic press from aluminum wouldn't make sense.

@Psycogeek I thought zinc can also form an object and not be used only as coating.

Psycogeek

sure garlic presses were often alum, probably chaging now because of not wanting that in your food.

Boris_yo

@Psycogeek Aluminum is known to leak stuff when in contact with food? How garlic presses were aluminum? They wouldn't manage to tolerate human's PSI and garlic's resistance.

Psycogeek

I think it is much rare for an item to be pure zinc, anodes for boats, ingots, roof and house flashing (but even those could be just coated.

@Boris_yo let me check I think this old one is alum, it is so lightweight.

it is non-magnetic, doesnt look like stock alum, i dont know what it is, made in italy.

IS garlic offset in PH?

Boris_yo

08:52

@Psycogeek Eh?

Psycogeek

is garlic acidic?

they made tons of Pans in aluminum uncoated before teflon was popular, getting food on aluminum was very common.

seives (them things with holes in em) for pasta were uncoated alum, even ice-cream scoops were made in an alum (or alloy)

now they coat the ice cream scoop (the special splitting spoon kind) with some other metal (or alloy) but the coating does not stay on under wear, not only wearing off but chipping and all.

How does rust form under a zinc coating ? probably because it is slopped on, different thickness in places. Some of the best "hurricane fencing" posts the fence and all exposed to water over and again, you can see rust places. wear and chipping.

heck you can even see that on older chrome over steel bumpers on cars and all. there must always be "flaws" in the coating process. after all it is probably done with methods that are fast and imperfect.

Boris_yo

@Psycogeek I don't know... media-cache-ak0.pinimg.com/736x/e0/a6/d9/…

Psycogeek

@Boris_yo barely different from water alkaline.

Boris_yo

09:08

@Psycogeek Water's PH is same as garlic's?

Psycogeek

so it is not a strong corrosive or oxidation agent. But this garlic press here certannly revels in a "patina" discolorations

i donno water is 7.6 or something

Boris_yo

Identify please. Material.

Psycogeek

machine shop people would know in an instant. cause they would know how it was ,umm poured into a mold thing.

and different metals would use different forms for the mold, and different metals would show scratches and sanding and all.

Oliver Salzburg

@Boris_yo It's papier-mâché, spray-painted silver

Psycogeek

i would say it is probably not coated. it probably is some sort of alloys, because loads of things they manufacture have blends they desire . What primary metal it is ?? I donno.

Boris_yo

09:16

@Psycogeek Compared to $50 garlic press, this one is lightweight that it feels as it would break when pressing hard garlic.

This can't be iron... Can this be fully zinc?

Psycogeek

i think zinc by itself would be to soft to make pliers and leverage tools and something like that.

and yes they all suck , i do not really like them as a tool, garlic doesnt just squeezee out like that so easily.

Boris_yo

@Psycogeek I have encountered screws that look like this material - a little pale. They are lighter than screws that look like were made from sturdy metal (stainless steel?) and heavy.

Big price difference...

Psycogeek

@Boris_yo if it is too light to be iron (mine seems to be to light to be iron). it is non-ferrous (so there is little iron in it). Then it seems like it would be too lightweight to be zinc. So what is the weight/volume of the 2 metals?

Boris_yo

@Psycogeek You want to know weight of my garlic press?

Psycogeek

zinc atomic weight 65.38 Iron 55.845 Ahh see, a zinc item Should weigh more then an iron one.

Boris_yo

09:27

@Psycogeek That's per ... ?

Psycogeek

@Boris_yo its what you would see on the periodic chart and is usually relative directaly to how much it would weigh in same volume

the
Rösle 12782 Garlic Press looks like it would be usable, better leverage, and heck it is german :-)

Pictures dont tell you how thick them hollow tubes are.

screw it, just use a grater or a chopper anyways, or put in sauce and run through blender. Real presses would have some gearing, huge leverage. everytime i use one of them garlic presses 1/2 the stuff is stuck in it still, whats the point.

Boris_yo

@Psycogeek Is chrome plating better than zinc plating durability-wise and aesthetically? I thought chrome plating has more polished look than zinc plating?

Psycogeek

09:43

chrome is usually a polished low porosity (slick top surface) seems to be much easier to clean

i think chrome is more durable, but (as always) it would totally depend. manufcaturing methods precision and the right ingredients, always beats out the china clone :-)

i think chrome (and alloys) are generally harder then the zinc.

Boris_yo

@Psycogeek So it's not about quality of chrome plating material in China but manufacturing process?

@Psycogeek Wait so chrome can also be solid mass and not only plating?

Psycogeek

@Boris_yo yup just like cookies :-)

they make everything nowdays as cheap crap, because people whine about price. Some things is better to have ONE $100 one than 10 $19 ones, because the $100 not only works better, last longer, less problematic, but just the gass to go to the store again :-) to get another cheap piece of junk

I should know i have all the Crap first :-)

it all belongs in the trash.

If it was good it was discontinued, because IF it was good you only sell one. what kind of corporate market would be in that :-)

Boris_yo

Psycogeek

side note, i have polished up a billet piece of aluminum, took hours, and it would be hard to tell it was not chrome, it is just one step down in luster.

Boris_yo

09:58

@Psycogeek And when it comes to stories I hear often about chrome plating chipping off?

Psycogeek

@Boris_yo yup, but look at old bumpers thick chrome plate, for the most part it stays.

it is when they save 4.5cents using less Of the expencive materials.

just like gold plated jewelery , all of it being cheaper than all gold, but there is the really cheap stuff that the gold top is so thin after some use it looks terrible.

they get it down to a science, just enough to be yellowish :-)

Boris_yo

@Psycogeek Like substituting chrome plating for zinc plating?

Psycogeek

i dont know? most of the zinc plating stuff is messy blobby, slopped on quick, designed for outdoors.

it looks somewhat similar to how a layer of solder would be slopped on it.

I dont know of any precision polished zinc, to know what that would be like.

and then forgot the fucking password to the goddamn private key

still haven't tied up the loose ends, but now at least it's running again

had to revert to old commit

that reminds me, I was trying to access my gitlab server at work, but nginx reverse proxy defaults to HTTP 1.0, and that fails with git chunked transfer if you have large files -_-

@allquixotic that's my strategy! :P

15:38

@Bob so, that's a better strategy than figuring out how to tell SmartOS/Solaris's init system (SMF) how to make everything work on startup? ^_^

Bob

o.O

@allquixotic half my vservers won't restart properly :P

gitlab being one of them

mostly cause linux-vserver with init system mismatch between host and guest means you can only use legacy sysvinit scripts on the guest

allquixotic

basically anything compiled from source (gateone, privoxy, stunnel) has to be manually restarted -_- it's annoying

@allquixotic try supervisord

allquixotic

@Bob it's not in the pkgin repos :/ this should be fun

Bob

(caveat: it doesn't work that well if your programs run as a daemon, since it uses sigterm or another signal of your choice to stop its children)

> Supervisor works on just about everything except for Windows. It is tested and supported on Linux, Mac OS X, Solaris, and FreeBSD. It is written entirely in Python, so installation does not require a C compiler.

Well... at least you have Solaris support? :P

allquixotic

15:43

that's a start

at least it doesn't use any Linux-only syscalls

Bob

@allquixotic I guess the 'best' way is to use the init system

allquixotic

only problem is, depending on the build system, the answer to the question "Are you Solaris or BSD?" ends up being "both!" or "Solaris! (lie)" or "BSD! (lie)"

Bob

but I find supervisord much easier... of course, I don't have to install that manually

I tried replacing the end of my gmail.com email address [email protected] with [email protected] but that didn't work Why is that?

in sending an email to [email protected] instead of [email protected]

Psycogeek

23:27

i donno do you also need a port to aim to?

barlop

well yes I did do the server and port.. it works with the 'to' email of gmail.com but not with the 'to' email of me@[ipofgmail.com]

Journeyman Geek

23:46

I'm confused to why you would assume that would work

allquixotic

@barlop email routing by IP is only possible over a LAN -- on the public internet, MX records have to be set up in the DNS for proper email delivery. also, many domain names map to many different IPs (e.g. round robin, load balancing, etc) and you're supposed to take the one you get, not a specific IP

Journeyman Geek

I was also thinking virtual mailboxen ;p

Basically your entire email address is what decides what mailbox to send stuff to

allquixotic

oh yeah, virtual mailboxen just like virtual hosts

layer 7 (and above, if you consider there to be distinct layers above the application layer) protocols are not required to treat accessing a domain and accessing an IP as equivalent acts

barlop

I know with web, you can http to a website domain(quite a specific one) and because you specify a host header, then when the website domain gets translated to an IP, it can be to the same IP but the host header goes to specific 'virtual' hosts.. I don't think that applies to email though

as there's nothing like a 'host' header

and also [email protected] is my whole email address as much as me@[ipofgmail.com]

Journeyman Geek

@barlop: it may reach the mailserver, but it may not get sent to the right mailbox

barlop

23:53

maybe a virtual mailbox would be if it was [email protected]

well, in [email protected] the 'me' identifies the mail box.

allquixotic

@barlop no it doesn't; [email protected] and [email protected] could map to the same IP address, but there's no requirement that they are the same mailbox just because those two domains map to the same IP address

4 mins ago, by allquixotic

layer 7 (and above, if you consider there to be distinct layers above the application layer) protocols are not required to treat accessing a domain and accessing an IP as equivalent acts

barlop

Ok..so the smtp server queries the DNS server with the domain after the @ of the email then I suppose.. rather than the IP after it

to get the mail server

allquixotic

SMTP, HTTP, etc. operate on top of the DNS layer, not on top of the IP layer. and the DNS layer does not map 1:1 to the IP layer.

there can be 60,000 IP addresses answering when you access gmail.com, or a single IP address answering when you access 60,000 separate domain names

it's a many-to-many relationship between IPs and domain names

Journeyman Geek

Or both ;p

barlop

DNS is layer 7.. and HTTP is layer 7 and SMTP is layer 7.. so what do you mean on top of?

allquixotic

23:58

@barlop in my mind I have imaginary layers on top of layer 7; I think it's just a matter of time before they update the standard models :P

layer 7 describes fully 85% of my job description (I rarely delve beneath that layer when doing anything technical) but I deal with such vast arrays of protocols and they are often layered one on top of the other, sometimes reaching layer 11, 12, 13

like SOAP on top of XML+HTTP on top of WSS on top of TLS
