Also
I
have
an
echo
but
the
the
the
project
that
we
finished
this
week
that
hopefully
anybody
has
noticed
that
the
wiki
is
now
migrated.
We
did
a
lot
of
updates
there.
There's
a
change
ticket
that
outlines
all
the
various
changes
that
took
place.
Most
important
thing
is
is
now
encrypted.
This
is
our
last
site
to
migrate
with
Europe
six
sites.
Migrating
is
now
on
one
server.
We
have
root
access,
we
have
much
more
control
and
that's
all
done.
We
can
get
rid
of
the
old
shared
hosting
server
and
I.
Think
you
mentioned
that.
C
C
Yes
sure
so
we
have
been
pretty
tired
to
Google
platform
for
documents,
as
well
as
hangouts
we're
using
jitsi
now,
but
it
isn't
really
that
scalable,
so
a
long-term
scheme
of
moving
towards
open
source
alternatives
that
we
can
host
ourselves.
One
thing
I
have
been
looking
at
is
a
open
source,
video
conferencing
system.
C
This
also
solves
issues
that
we
run
into
with
jitsi,
which
uses
WebRTC,
which
the
relatively
new
technology
that
was
built
for
real-time
communication
in
such
as
a
video
and
microphone
in
by
Google
actually,
and
it's
what
hangouts
uses
and
it's
what
also
jitsi
uses.
But
you
have
some
scalability
issues
with
a
person-to-person
web
RTC
session.
C
Where
you
have
you
know,
once
you
reach
like
seven
people,
you
have
a
connection
going
from
every
person's
machine
to
every
other
person
that
machines
doesn't
scale
very
well,
it's
better
to
have
kind
of
like
a
centralized
server
that
can
take
everything
and
then
selectively,
send
now,
for
example,
if
you
can
only
send
out
the
person
who's
currently
speaking
and
then
that
scale
is
significantly
better
and
that's
called
a
selective
forwarding
unit.
So
jitsi
is
actually
run
by
a
company
called
Atlassian
that
bought
a
open-source
project
called
jitsi
jitsi
meat
as
one
of
their
products.
C
They
also
have
a
gateway
that
backs
jitsi
meat,
Atlassian
runs
should
see
meat,
which
is
what
we're
using
right
now,
but
we
can
on
that
ourselves.
I've
looked
into
it.
It's
non-trivial
uses
no
hood,
which
doesn't
play
well
with
a
current
platform.
Another
alternative
is
made
by
a
company.
An
Italian
company
called
mutual
looks.
Like
me,
eco.
C
So
you
have
like
multiple
workshops
during
an
extreme
ability
of
multiple
people
at
the
same
time,
alternating
and
publishing
content-
and
you
have
a
lot
of
viewers-
those
viewers,
don't
necessarily
need
to
publish
the
content,
all
comes
from
a
central
server.
You
have
that
selective
forwarding,
search
skills
so
significantly
better.
C
Yeah
so
Janice,
like
a
proof
of
concept
up
and
around
a
freenode
right
now,
I,
don't
I,
don't
think
it'd
be
great
to
throw
on
or
serve.
It
would
be
issues
that
that
could
present
for
our
web
sites,
which
are
pretty
high
availability,
critical,
so
I'm
probably
going
to
get
a
because
WebRTC
is
Snowden
and
has
a
lot
of
encryption
requirements.
You
have
to
run
on
HTTP.
So
for
brief
concept.
I
have
to
mint
a
new
private
certificate
for
testing.
C
I
didn't
do
that
yet
put
that
on
the
server,
and
then
we
can
try
in
a
future
meeting
to
use
it
and
may
require
some
vellum
to
get
to
do
exactly
what
we
want
it
to
do
for
our
needs.
But
I
think
the
next
test
would
be
this
meeting
to
try
it,
but
I
need
to
do
a
little
bit
of
groundwork
to
make
it
ready
for
us
to
use
there.
C
Yeah
I
would
definitely
introduce
some
security
risks.
I
mean
the
software
itself
wasn't
designed
to
be
extremely
secure,
its
opening
another
point:
if
it
has
some
sort
of
remote
execution
issue,
then
it
could
take.
You
know
it
would
affect
our
Savior,
but
also
person-to-person.
Communication
is
pretty
complicated,
so
you
have
a
technology
called
ice
that
sits
between
uses
stun
and
turns
to
reduce
to
be
able
to
route
traffic,
and
that
requires
a
lot
of
UDP
ports
to
be
up
another
server
which
could
present
issues.
C
C
Yes,
so
it's
up
right
now
and
I
just
have
to
get
the
certificate
minted.
So
maybe
a
couple
weeks
depends
on
the
other
priorities.
I've
been
mostly
focusing
with
the
wiki
and
also
one
thing
I've
been
doing
nothing.
He
is
working
with
a
3d
printer,
so
it's
been
kind
of
solved,
but
you
know
it
would
probably
take
a
whole
day
is
to
make
it
ready,
I.
Think
for
us
to
use
a
couple
days
of
my
time.
C
D
D
You
know
looking
at
more
details.
What
I
was
gonna
put
the
oil
fill
points
drains.
There's
an
oil
fill
and
drain
on
either
side.
That
kind
of
thing
it
needs
to
be
extended.
There's
certain
the
mount
is
a
little
wide
and
obviously
all
the
bolt
holes
and
everything
need
to
be
pretty
accurate.
Since
we're
gonna,
try
to
see
and
see
cut
all
this
stuff,
so
I
think
it
was
pretty
close.
D
I
think
I
think
the
the
measurements
of
stuff
from
the
photos,
I
think
I
can
see
where
I
can
get
all
that
information
off
there
to
edit
the
engine
file
I'll
just
edit
the
old
engine
file
I've
got
it
open
and
it's
pretty
durable
so
that
shouldn't
take
long
to
correct
that
most
of
it
is
probably
fine,
but
I
think
that
the
frame
is
actually
gonna.
The
depth
will
have
to
be
a
few
inches
longer
because
the
the
engine
it
doesn't
need
to
be
a
bit
deeper
from
front
to
back.
D
So
I
may
add
a
few
inches
to
the
frame
yet,
but
a
little
more
than
I
thought,
but
there's
space
in
there
already
but
and
then
I'll
have
to
start
propagating
some
of
these
updates
to
the
other
frame
for
the
smaller
cube.
But,
let's
see
oh,
then
there
was
a
there's
a
cap
on
top
different,
not
the
cat
filled
cap
but
I
think
it's
an
air
breather
cap
on
top
of
that
engine,
that's
taller
to
which
I
had
noted
before
and
that
hadn't
been
updated
either.
D
So
I'll
just
make
the
the
frame
notches
top
and
bottom
symmetrical
and
that
that
should
enable
the
engine
to
be
taken
in
and
up
either
side.
I
did
get.
Let's
see
some
plumbing
fittings
done.
I
guess
this
week,
two
extra,
the
SAE
and
yeah
I
had
to
emailed
you
about
the
change
it
sound
like
you
changed
the
pump
at
some
point
on
17
into
the
to
the
point.
Six
one
cubic
inch
model,
I.
Think
I.
Think
that
sounds
like
it's
close
enough.
D
I
also
did
some
work
looking
more
at
free
CAD
and
there
was
a
pipe
work
bench
and
might
even
get
too
much
Lemang
go,
but
I
looked
at
some
of
that.
I
know
we're
talking
about
freecad
earlier
in
general
on
point
16.
The
legacy
version
which
I'm
still
using
wish
to
edit
stuff,
but
they
all
see
part
workbench,
is
some
of
the
issues
there.
D
That
would
see
glitches,
sometimes
with
some
of
the
parts
I
think
are
related
to
the
new
part
workbench
it's
more
compatible
4.17,
which,
for
some
software
issues
and
stuff
that
that
kind
of
makes
more
sense,
maybe
Messala
might
have
to
technically
tell
more
about
that.
Maybe
I'm
wrong
about
certain
abilities
there,
but
that
seemed
to
be
with
the
part
system
is
because
my
understanding
is
even
though
we're
we've
got
a
lot
of
kind
of
legacy
stuff
with
the
common
point,
one
six,
the
legacy
of
freecad.
D
Now
that
that
part
workbench
should
be
better
overall
for
four
parts
design
in
the
future,
because
they're
they're
kind
of
it
lets
you
do
different
things.
It's
just
an
improvement
and
there's
gonna
be
more
improvements
we
might
be
a
year
behind
and
and
they
assembly
to
work
which
we
said
is
is
kind
of
buggy.
In
other
ways,
too,
you
have
to
kind
of
minimize
your
use
of
that
keep
the
some
files
small.
D
D
Latest
power
cube,
I,
haven't
adjusted
the
power
cube.
Let's
see,
I
didn't
yeah,
I
didn't
add
the
the
fittings
that
I
made
it
to
the
the
new
power
cube
I'm,
going
back
and
I'm
working
on
the
engine.
Still
so
I
haven't
actually
dated,
who
recently
I
didn't
notice
that
it
wouldn't.
Let
me
upload
I,
don't
think.
D
D
D
Oh
no
yeah
I
guess
maybe
that's
more
of
an
issue
with
the
way
the
wiki
database
I,
don't
know
how
it
versions
files
because
most
modern
file
systems
or
understand
ZFS.
They
do
do
a
lot
of
deduplication,
but
the
wiki
I
don't
know
how
it
stores
that
I
know.
It
is
databases,
I'm
sure
Michael
probably
knows
about
that,
but
yeah
yeah
I,
don't
yeah.
So
maybe.
C
C
I'm,
so
actually
it's
not
storing
the
database.
It's
is
stored
in
a
file
system
and
the
file
system
is
not
ZFS,
but
I.
Don't
think
ZFS
would
would
be
duplicate
at
the
I
mean
I.
Look
at
the
file
event
about
the
block
level.
You
had
a
verse,
slightly
changed
power
cube
if
it
would,
if
it
actually
do
duplicate
that,
but
we
have.
The
wiki
is
I,
think
almost
20
gigs,
most
of
its
images
that
are
uploaded,
and
it's
really
just
to
future
deal
with
it.
D
C
If
you
can
have
a
physical
machine
and
just
throw
our
drives
in
and
by
then
it'd
be
cheaper,
but
you
know
regardless,
if
we're
gonna
be
buying
from
somebody
else.
If
we
don't
have
our
own
data
center
for
gonna
be
buying
from
somebody
else
that
cost
grow
significantly,
and
then
you
talk
about
backups
and
having
to
store
the
backups.
You
know
that
you
know
over
time
and
many
many
copies
and
it
all
day
is
multiple
months,
multiple
years
that
really
explodes
a
lot.
If
you
don't
have
our
own
hardware,
yeah.
D
D
For
let's
see
the
micro
track,
I
was
looking
at
that
because
I
was
trying
to
see
if
he
how
he
had
the
if
he
had
the
power
engine
and
any
of
that
that
those
aren't
I
guess
sub
parts
listed
in
his
github
repo
for
the
micro
check,
but
we'll
just
have
to
migrate
that
over
okay
I
think
she
did
I
concur
on
long
yeah
under
try
to
keep
short,
I.
Think
I,
don't
think
I
have
any
questions.
D
Let's
see
about
I,
think
I
know
what
I
need
to
know
to
fix
the
engine
module
and
everything
we
updated
that
and
the
cube
a
little
bit
more
and
you've
got
most
of
the
plumbing
parts.
I'm
gonna
have
to
dress
some
more
quick
adapters.
We
have
some
drone
and
the
some
drawn
in
the
fittings
library,
but
got
to
draw
a
few
more
sizes
of
plumbing
parts,
and
that's
probably
it
I
I
was
noticing.
D
I
was
trying
to
see
how
the
piping
workbench
could
be
used
to
try
to
adapt
more
of
these
fittings,
but
the
slight
differences,
and
that
ought
to
do
eventually
that
that
could
be
feasible
to
redraw
the
right
dxs
and
get
the
dimensions
right.
Some
of
these
fittings
can
be
just
be
drawn
in
real
time,
probably
in
the
workbench,
but
that
that's
gonna
require
a
bunch
of
I.
Don't
know
that,
there's
a
lot
of
code
rework
on
some
of
it.
D
D
D
B
Turn
this
last
week,
I
met
with
some
people
from
OSCE
by
Germany,
and
they
they
have
all
very
building
a
more
official
organization,
nonprofit
organization,
and
there
is
a
some
some
project
which
cooperate
with
open
source,
ecology
Germany,
for
example,
I
put
epital
I
will
explain
you
later.
They
are
not.
B
B
B
B
B
B
B
D
B
B
C
B
B
The
meeting
with
Martin
Yeager-
it
was
yes,
it
was
a
rock
meeting.
We
we
discussed
some
some
tests,
they
performed
in
the
laboratory
and
what
went
wrong,
how
we
can
improve
it.
I
even
tried
to
remember
the
Taylor
analysis,
--tz--,
a
very
Union
University
and
try
to
to
estimate
errors
and
how
they
think
is
working
and.
B
B
B
B
B
D
B
B
B
A
Yes,
it's
going
alright,
so
I
was
able
to
do
some
cuts
from
the
PVC
pipe
which
fit
exactly
the
lengths
of
the
steel
rods.
I
cut
for
the
accesses,
so
it's
the
awesomeness
of
CAD
that
was
pretty
cool,
see
that
coming
together,
so
yeah
I
have
founded
my
the
belt
tensioners
and
again
electronics
setup
and
you
know
just
kind
of
wrapping
up
the
design
had
a
bunch
of
delays
there
with
McMaster
getting
me
longer
rods.
That's
one
thing:
I
noted
I
need
a
bit
more
rods.
A
The
cross
for
the
z-axis
so
have
those
coming
in,
but
just
looking
good
I
mean
so.
The
one
thing
you
know,
Marcin
I
discussed
was
with
the
extruder.
I
currently
have
purchased
the
mark
aid
extruder,
but
we
want
to
try
the
pro
so
I
three
mark
two
extruder
for
the
printer,
so
right
I
was
didn't,
get
those
parts
from
Stephen.
Originally
I
knew
we
have
a
new
model
out
there.
So
intention
was
printed.
He's
tried
recently
on
the
market,
got
a
jammed
up
soaked
in
acetone,
hoping
the
printed.
A
If
I
can't
I'll
either
have
a
you
know
online
company
printed
or
see.
If
someone
in
the
team
can
help
me
I
will
prints
get
that
extruder
out
right
and
just
get
east
ups
and
all
the
rest
of
that
kind
of
stuff.
I
know
I.
You
did
the
calculations
and
the
basic
math
for
the
e
steps,
but
that
Mark
eight
got
nothing
but
troubles
from
the
beginning
on
it
under
under
extruding
or
chipping
away
at
the
yo
filament
and
not
extruding,
or
does
that
I've
had
just
not
nothing
but
issues?
A
It's
a
GE
tech
tree
tech
and
a
couple
other
Chinese
manufacturers
I
didn't
nothing
but
issues
with
that
extruder
really
for
keeping
temperature
I'm
mad
tackle.
They
do
a
detailed
analysis
of
it
quite
yet
see.
What's
failing
but
yeah,
so
hoping
and
get
things
up
and
running
at
least
initially
this
week
that
I
get
some
basic
print
stun
this
week
or
next
week.
A
Yeah,
the
awesome,
a
eieio
feh
invoice
me
or
whatever
for
those
or
donate
appreciated,
so
yeah
I
mean
it
that
that's
really
that's
really
block
their
the
rest
of
stuffs
up
and
taken
care
of,
and
you
know
it's
doing
lots
of
stuff
him
over
here
in
a
verification,
lab
got
PLC,
fives
and
all
the
rest
of
that
kind
of
stuff
around
me.
Getting
lift
stations
Commission's,
so
I
had
a
lot
of
racist
stuff
over
years.
An
engineer
doing
this,
some
pumps
for
a
city,
it's
pretty
cool
stuff,
but
sometimes
a
system.
A
A
A
A
A
A
A
A
So
yeah
we
want
to
get
the
3d
printed
parts
and
we
want
to
get
the
Haab
bolts
again
versus
gear
so
that
I
had
never
had
anything
wrong
with
a
hot
new
bolt.
That's
been
reliable
for
me.
Always
that
would
be
the
big
Streeter
that
broke
after
working
for
like
five
years
on
the
air.
Wolf
was
just
hopped
bolt,
so
yeah
definitely
makes.
C
A
Yes,
it
is
yep
yeah,
that's
what
that
looks
like
it's.
Oh
man,
it's
gigantic!
I,
tell
ya!
Yes,
I
see
that
right,
every
tool
chest
right
back
there,
so
you
has
a
12-inch
bed
and
I
was
able
to
update
my
sourcing
document
and
keeping
those
up
to
date
in
my
log
page
for
this.
But
you
don't
have
that
big
old
rubber
heat
bed
that
goes
in
the
back
I
found
a
$30
source
for
those
beds.
A
It's
been
that
Co
seems
to
be
working
pretty
well
for
me,
so
I
mean
and
that's
why
I
had
just
a
couple
questions
up
real
quick
here.
So
first
one
number
one
is
for
the
bed.
Are
we
just
attaching
the
silicon
heater
to
the
back
of
the
metal
plate
and
then
putting
the
p:v
a
sheet
on
top
on
a
metal
sheet?
Oh.
A
D
A
A
Now
is
that
to
attach
the
pea
and
ice
sheet
to
the
bed?
Okay,
right
cool,
so
I
have
that
so
looks
like
the
materials
for
that
and
the
one
thing
I
also
was
missing
as
far
as
parts
as
I
I
realized
that
I
only
have
you
know
for
the
actual
heated
bed
suspending
it
across
that
to
z-axis
units.
You
don't
see
the
other
one
in
the
image,
but
there
are
two
Z's
in
this
bill.
I
only
have
one
of
the
short
idlers
left
with
what
Stephen
printed
me.
