Memory used: Unknown of 16K bytes (Unknown bytes free)
Explain
This shows the total RAM usage on the KL25Z for your current configuration.
Memory usage is mostly static; the software allocates memory during initialization
after the device boots up. You shouldn't see any fluctuation during normal use.
Memory usage changes only when you add or remove features via the settings below,
and only updates after you save the new settings. Since memory is assigned
during startup, the software doesn't need much free memory to run, so don't
worry if the free space looks tight. We show the memory figure mostly for
diagnostics, and to give you an idea of how much headroom you have left for
enabling additional features.
System type. Are you using this KL25Z on its own,
or with a set of expansion boards? Help
If you're using the
Pinscape expansion boards, the
Oak Micros Pinscape All-in-One,
Oak Micros Pinscape Lite, or
L'atelier d'Arnoz Boards, select the corresponding option below, and the
setup tool will automatically fill in the pin assignments throughout the configuration.
If you're using the KL25Z by itself, or you're using your own custom add-ons
(e.g., your own output booster circuits), select "stand-alone" so that you
can set the individual pin assignments to match your wiring.
Expansion board details:
Number of MOSFET power boards:
Number of chime boards:
Number of Mollusk boards:
The KL25Z pin assignments are hidden by default because you've selected an
expansion board configuration. All GPIO pin assignments are set automatically in
this configuration to match your boards, so there's normally no need to view them.
You can check the box above if you want to see the pin assignments
anyway, but be aware that any changes you make to the pin settings will
probably cause malfunctions, because the boards are hard-wired to
specific GPIO pins that the software settings have to match for the
boards to work properly.
USB Identification. This is how the KL25Z identifies itself to
Windows through the USB port.
Vendor ID:
Product ID:
If you have a real LedWiz unit in your
system, choose LedWiz Unit 8 for your first Pinscape
unit, 9 for the second, etc.
If you don't have any real LedWiz units, choose
LedWiz Unit 1 for the first unit, 2 for the second, etc.
For LedWiz compatibility, choose an LedWiz unit number.
LedWiz compatibility lets older programs, like Future Pinball,
control outputs through this Pinscape unit.
LedWiz unit numbers must be unique.
Be sure to choose an ID that isn't used by your real LedWiz, or by another
Pinscape controller.
Programs on the PC use the unit number to tell the devices apart, so each
device needs a different number.
If the LedWiz IDs cause conflicts on your system with other USB devices,
you can try the Pinscape ID. This ID is registered uniquely to
Pinscape, so it shouldn't conflict with anything.
However, using this ID will give up LedWiz compatibility. This
means that older software like Future Pinball won't be able to access
the output controller features. Newer software based on DOF R3
(such as Visual Pinball and PinballX) will still be able to take
full advantage of the output features. The input features shouldn't
be affected one way or the other.
The Custom ID option is only for techies doing something
tricky. Don't use it unless you have a good reason. Using a
custom ID will make the output features unreachable even from DOF.
(The input features will still work, though.)
Pinscape ID. This is a separate ID from the LedWiz
unit number. DOF R3 and the
DOF Config Tool use this ID to identify the unit.
Set this to 1 for your first unit, 2 for the second, and so on.
You don't have to copy the LedWiz unit number here!
This is completely unrelated to the LedWiz number. This setting
must always be 1 for your first (or only) Pinscape
unit, or DOF won't be able to access it.
Reset on disconnect. If the USB connection is broken, and
can't be re-established within a time limit, the KL25Z can
automatically reset itself as an attempt to fix whatever's wrong.
Select the time interval (in seconds) before this happens.
Details
On some systems, the KL25Z has trouble re-establishing a broken
USB connection, such as after rebooting or power-cycling the PC.
This can usually be solved by resetting the KL25Z. If you set
this option, the KL25Z will reset itself automatically when it
detects a broken connection and can't reconnect within the specified
time limit. The delay is there to avoid unnecessary resets when
the connection only glitches momentarily. The recommended setting
is 10 seconds.
TV ON switch. If one or more of your monitors needs to be turned
on manually every time you power up your cabinet, you can use this feature
to switch them on automatically. See the Build Guide for wiring instructions.
This is how long to wait after power-on before pulsing the relay
IR Remote Control. The controller can send and/or receive IR
remote control signals if you attach some additional components. This
can be used with the TV ON feature to turn
your cabinet TVs on via IR commands at system startup. See the Build
Guide for details on the components required and how to connect them.
If you don't have any IR components attached or wish to disable them,
simply set the pin assignments here to "Not Connected".
IR LED (transmitter) pin:
Requires a PWM-capable pin
IR receiver input pin:
Requires an interrupt-capable pin
The firmware version installed on your device doesn't support the IR
remote features. Update to the latest firmware to enable these features.
IR Command List. You can program the Pinscape unit with remote
control commands that it can then send and receive. Each slot below
stores one code. Help
Note: your current firmware version can store up to
0 codes. The list above
will automatically expand as you fill in new rows, up to the
limit.
Joystick input. The controller acts like a Windows USB Joystick
in order to send the plunger position, accelerometer readings (for nudging),
and button inputs to the PC. You can disable these inputs if desired.
Why would I want to disable this?
By default, each Pinscape unit reports its accelerometer readings
to the PC via the joystick interface. If you have more than one
unit installed, that means you'll have more than one set of these
reports coming in. The extra reports can confuse some pinball
software, and can also affect system performance. This option
lets you disable the extra reports from the secondary units. If
you have a plunger attached to one of the units, you should consider
that one to be your primary unit and leave its joystick interface
enabled. You should disable the joystick interface on any other units.
A real joystick reports the
position of the stick by sending an "X Axis" value for the left/right
position of the stick and a "Y Axis" value for the up/down position.
It can also send a "Z Axis" value to represent another control like a
throttle. Normally, Pinscape uses these same three axes, by
sending accelerometer readings on the X and Y axes, and plunger
readings on the Z axis. The USB protocol for joysticks also defines
a set of "rotational" axes called Rx, Ry, and Rz. Real joysticks that
allow twisting motions report those motions on these "R" axes.
If you wish, Pinscape can report its normal readings on the "R" axes
in place of the normal X/Y/Z axes.
Why would you want to use the "R" axes? In most cases, you wouldn't;
the normal X/Y/Z settings are recommended because they're compatible
with most software. However, the "R" axes can be useful if you have
other joysticks in your system that are conflicting with Pinscape.
If your other joystick is reporting its input on the normal X/Y/Z
axes, and it's creating problems with VP or other software, you
might be able to fix the conflict by telling Pinscape to use the
Rx/Ry/Rz axes instead.
If you change the Pinscape axes, you also have to reconfigure
Visual Pinball and any other pinball players to use the Rx/Ry/Rz
axes. Future Pinball has no way to read the Rx/Ry/Rz axes,
so using these in Pinscape will make it incompatible with FP.
You might run into the same limitation in other software. Because
of the compatibility issues, you might find that it's better to
reconfigure the other joystick that's creating the conflict,
if possible, since that would let you continue using the more
compatible X/Y/Z axes for Pinscape.
This lets you set the time between the joystick reports that the
device sends to the PC on the USB connection. These reports send
current information on the accelerometer readings, plunger position,
and the button-press status for any buttons assigned to the joystick.
Pinscape is capable of sending reports as fast as every 1 to 2
milliseconds. (The exact speed depends on the type of plunger
sensor and other external hardware you're using.) But we
actually don't want to send reports as fast as we can, because
Windows and Visual Pinball can't digest them at that pace. This
setting lets you slow down the reports to a suitable rate
for the PC.
Recommendation: start with an input time of 8.333ms
and an "accelerometer stutter" setting of 2. This should
work well on most systems, but it's not necessarily optimal for
everyone, because VP's timing characteristics can vary according
to your PC setup. You might have to experiment to find the
ideal settings for your system. After adjusting the timing,
test nudging with VP. If it seems natural, keep the settings.
If VP's response to nudging seems erratic (for example, it ignores
some nudges, but overreacts to others), try different timings.
It's best to keep the setting in a range from about 5ms to 20ms.
Anything shorter than 5ms will be too fast for Windows to digest
properly, and anything longer than 20ms might produce excessive
latency (games respond slowly to button presses and nudges).
The "stutter" setting works in connection with the joystick
report interval above to set the interval between accelerometer
reports. The accelerometer reading is sent as part of the joystick
report, so the base interval between accelerometer readings is exactly
the same as the joystick report interval. This setting lets you
slow down the accelerometer readings to a multiple of the joystick
interval.
The stutter is the number of times that each physical accelerometer
reading is repeated in sequential joystick reports. If you set the
stutter to 1, it means that a new reading is sent with every joystick
report sent to the PC. If you set it to 2, a new reading is sent
with every other report, and the alternating reports simply
repeat the prior reading. If you set it to 3, a new reading is taken
every three reports.
Why would you want to slow down the accelerometer readings? Because
VP can't use the readings if they arrive too quickly. For best
results in VP, readings should only be sent once per video cycle.
If your graphics card is set to a 60Hz refresh rate, the video
cycle is 16.667 milliseconds long, so VP will work best if you send
accelerometer readings every 16.667ms. However, you might want to
send joystick reports faster than this, so that joystick button
updates are sent closer to real-time. This is where the stutter
setting comes in: it lets you send joystick reports at a fast
pace for lower button latency, but slow down the accelerometer
readings to accommodate VP's slowness reading them.
Recommendation: start with a joystick report interval
of 8.333ms and a stutter setting of 2. This will
read the accelerometer at 60Hz, which is usually optimal for
VP, but will send button input updates twice as often, which
might make other programs that use joystick buttons more
responsive. The optimal timing in VP can vary according to
your PC setup, though. Check your video card refresh rate
(use the video card rate, not the monitor's refresh
rate). If it's not 60Hz, choose a report interval close to
10ms that divides evenly into the refresh interval, and choose
a stutter time equal to the refresh interval divided by the
report interval. If your video card refreshes at 120Hz,
for example, use an 8.333ms interval and set stutter to 1.
Accelerometer orientation. If you're using the accelerometer
(for nudge sensing), the software needs to know how the KL25Z is oriented
in the cabinet so that it can report motion in the right direction. Install
the KL25Z in one of the orientations shown below, level with the floor of
the cabinet, with the chips and LEDs facing up.
Dynamic range. Select the range for
accelerometer readings. Ranges above ±2G have lower precision.
Details
The KL25Z accelerometer hardware has three native range settings:
±2G, ±4G, and ±8G. (A "G" is the acceleration
of the earth's gravity, 9.8m/s².) The device offers the options
because each is a compromise between precision and dynamic
range, and some applications care more about precision while others
care more about range. Precision is the ability to discern
the difference between nudges that are very close together in
strength. Dynamic range is the ability to tell the difference
between nudges that are very far apart in strength. In the 2G range,
the device has the best precision, but the tradeoff is that readings
are capped at 2G, so real accelerations that are higher than 2G will
read as 2G. The 4G and 8G ranges increase the cap, allowing for true
readings up to the respective limits, but the tradeoff
is that they lose some of the ability to distinguish readings that
are very close together.
For virtual pinball use, the 1G or 2G settings are recommended,
because precision is more important to us than range. It makes it
more realistic if the game can discern fine shadings of strength.
It's not as important to distinguish very high accelerations from
one another, since anything beyond a certain point is just a
TILT anyway.
1G is the default because it was the fixed setting in older versions
of the Pinscape firmware, before this option existed. 1G will produce
the same effects you're used if you had previous versions installed.
If you wish, you can change to 2G with no loss of precision, because
1G and 2G use the same native device settings. If you do change to
2G, you should adjust your VP "axis gain" settings (in the keyboard
preferences) to compensate, by doubling the old settings. Similarly,
if you decide to try 4G or 8G, double the gain settings again at 4G,
and yet again at 8G.
Auto-centering. The controller automatically zeroes the
accelerometer after it's been sitting still for a while. This
compensates for any tilt in the mounting position. If you prefer,
you can disable the automatic centering, and center it manually
when needed using the Joystick Viewer.
Time in seconds:
1-60 seconds
The firmware version installed on your device has a fixed ±1G
dynamic range for the accelerometer, and automatic centering (zeroing)
after being motionless for 5 seconds. Update to the latest firmware
if you want to customize these settings.
TSL14xx optical sensor. This is a large
optical sensor with the pixels arranged in a single row, about 3" long.
We detect the plunger position by reading the image from the sensor and
looking for the shadow cast by the plunger. The edge of the shadow tells
us the plunger position.
TSL1401CL bar code sensor. This is a small optical sensor that we
use to read the plunger position from a bar-coded "scale". The scale has
a series of tiny bar codes across its length, with each bar code representing
its position. As the plunger moves, the sensor slides along the scale, and
we can read the current position by scanning the nearest bar code. This
requires the specially printed scale with bar codes in the format
the software recognizes.
Important! Don't confuse this with the TSL1410R. This option
is for the TSL1401CL, which is a completely different sensor
from the TSL1410R. The two are at the opposite extremes of
the size scale, so they can't be used interchangeably despite the
confusingly similar names. The TSL1401CL is about 8mm long, and we
use the small window to read a compact bar code. The other
sensor is about 3" long, and we use to take pictures of the plunger
directly. Choose TSL1410R instead if you're using that other,
larger sensor.

Potentiometer. This uses a slide potentiometer,
which is a variable resistor with a control knob that moves linearly
across the length of the device. Attach the control knob to the
plunger so that the knob moves with the plunger. The pot's
electrical resistance changes as the knob moves, proportionally to
the position, so the controller can determine the plunger position
by reading the voltage on the input.

TCD1103GFG linear image sensor. This is a small image sensor with

plunger position by taking an optical image along the length of the plunger,
and analyzing it to determine where the plunger is located within the image.
This sensor requires some extra setup besides the sensor chip. It needs
an optical lens to focus the image on the sensor, and it also requires
some specific interface circuitry between the sensor chip and the KL25Z.

Plunger auto-zeroing: If this is enabled, the firmware will automatically
reset the plunger position to zero after it hasn't moved for the minimum time selected.
Details
Quadrature sensors use purely relative positioning, so they need a fixed
starting point. We use the plunger's "park position" (where it comes to
rest when you're not moving it manually) as the natural zero point. If the
sensor ever misses any plunger motion, or if the plunger isn't at rest when
the system is powered up, the relative position counter can get out of sync
with reality, making the on-screen plunger a little off from the real position.
The firmware can correct for this by automatically zeroing the on-screen
position (setting it to exactly the park position) whenever the plunger remains
at rest for a minimum time period. It's usually safe to assume that the plunger
is at the park position when it hasn't moved in a long time, since you don't
normally hold it still anywhere else for long periods. You only need to
enable this if the plunger doesn't always stay in perfect sync on its own.
Choose a long enough time period that you probably won't ever hold the plunger
away from the park position for that long in normal play.

ZB Launch Ball setup. You can set up your mechanical plunger
to act as a "virtual" Launch Ball button for tables that use a button
instead of a plunger.
Details
This feature lets you use a mechanical plunger in lieu of a Launch Ball button,
for tables that need it, in case you don't want to install a separate physical
Launch button. When this is enabled, you treat the plunger knob like a button:
push it a little forward to "click" the button. You can also pull back and
release the plunger to simulate a brief button push.
The feature is only activated when a non-plunger table is running
on the PC. We can tell because Visual Pinball turns on the output port
selected below when such a table is loaded.
The port you designate can be any type, including a "virtual" port that
isn't connected to any physical output wiring.
In the DOF Config Tool, be sure to
set the port number you designate here as your ZB Launch Ball port.
That connects everything on the PC to the right port.
Select the keyboard key or joystick button to send to the PC when
the plunger triggers a launch. This is usually the Enter key, because
that's what almost all PC pinball software uses.
The push distance sets the sensitivity. When you push the
plunger forward by this amount or more (and the feature has been activated by
the output port), the controller simulates pressing the Launch Ball button.
Set the distance far enough that it doesn't trip randomly, but short enough
that you don't have to push too hard. We recommend about .06 to .08 inches.
(The ZB Launch Ball feature only applies when you have a
plunger sensor installed.)
Output port number:

The TLC5940 is an integrated circuit chip that you can connect
to the KL25Z to add extra outputs for more feedback devices (lights,
solenoids, motors, etc). TLC5940 outputs have full PWM (Pulse
Width Modulation) capabilities, allowing the software to control
the brightness of an attached light or the speed of a motor. The
DIP version of this chip is no longer being manufactured, so you
can't order them from most distributors, but they're still easy
to find on eBay and elsewhere.
These chips let you go beyond the KL25Z's limited PWM capabilities.
The KL25Z only has 10 PWM channels of its own, which isn't enough
for most virtual pinball machines. Each TLC5940 chip provides 16 PWM
outputs, and you can connect two or more of the chips in a daisy chain
to add almost unlimited outputs. Only five GPIO pins are needed to
control the whole chain.
The Pinscape Expansion Boards use these chips to provide extra PWM
outputs. You can also install them with your own custom wiring. The
circuitry needed is outlined in the Build Guide. The settings below
configure the data signal connections between the KL25Z and the TLC5940's.
The TLC5940 configuration is automatically set up for your expansion boards.

The TLC59116 is an integrated circuit chip that you can connect
to the KL25Z to add extra outputs for more feedback devices (lights,
solenoids, motors, etc). TLC59116 outputs have full PWM (Pulse
Width Modulation) capabilities, allowing the software to control
the brightness of an attached light or the speed of a motor.
These chips let you go beyond the KL25Z's limited PWM capabilities.
The KL25Z only has 10 PWM channels of its own, which isn't enough
for most virtual pinball machines. Each TLC59114 chip provides 16 PWM
outputs, and you can connect up to 14 of the chips. Only three GPIO
pins are required no matter how many of the chips are attached.
The TLC59116 is a successor to the TLC5940 (see above) with a more
modern design. It's only available in a surface-mount (SMD) package,
which makes it a little harder to work with than the traditional DIP
form factor of the TLC5940NT. This chip is not interchangeable
with the TLC5940, even though it has a similar function, since it
has a different physical pin layout and a different software interface.
Each TLC59116 has its own unique address, set via the A3 A2 A1 A0 pins
on the chip: a pin wired to + voltage is a "1" and a pin wired to GND
is a "0". Select the addresses of the chips attached to your system
according to how you wired the address pins. Addresses 8 and 11
aren't shown because they're reserved for special purposes.

74HC595 (external digital out chip) setupWhat's this?
The 74HC595 is an integrated circuit chip that can be connected
to the KL25Z to add more digital outputs for feedback devices like
solenoids and replay knockers. "Digital" means that the outputs
are strictly on/off: the software can't modulate intensity or brightness.
Digital outputs are ideal for feedback devices that inherently need only
on/off control, such as solenoids.
The Pinscape "Chime Board" uses this
chip to add outputs for replay knockers and chime units. You can also
add these chips with your own custom wiring; the circuitry is described
in the Build Guide. The settings below let you configure the data
connections between the KL25Z and the 74HC595's.
The 74HC595 configuration is automatically set up for your chime boards.
The 74HC595 configuration is automatically set up for your Pinscape AIO or Pinscape Lite.

Pinscape After Dark. You can set up a button or switch to
activate Night Mode, which disables the feedback device outputs
that you designate as noise-makers. This lets you play during late-night
hours without disturbing your party-pooper housemates and neighbors.
Details
Select an input button to turn
Night Mode on and off. Wire this like any other button.
You'll probably want to configure the button you select
for "No PC Input" in the button setup,
but you can have it send a keystroke if that's useful to you for
some reason.
If you don't want to wire a physical button for this, just
set the button number to 0 (zero). You can still control Night
Mode with the NightMode.exe program on the PC (it's in your
Pinscape Setup Tool folder).
You can also optionally select an output port to serve as an
indicator light, so that you can tell when night mode is turned on.
If you don't need an indicator, just set this to 0. If you do assign
a port, you should leave it unassigned in your DOF port layout.
Feedback device outputs. Pinball software on the PC can control
output devices connected to the KL25Z to create special effects during play,
such as tactile feedback and lighting displays. The PC software uses the
port numbers in the list below to address the outputs. Use these
port numbers when you set up your DOF configuration.
For each port, you can select the physical output pin that the port is wired to.
A "virtual" output is a software port that isn't connected to
a physical output. This can be used as a placeholder in your
DOF setup, or for a special function, such as the ZB Launch Ball
control port.

I think there is less than 50 BTC on the sell side to 50k sats
most of the sell side is a dynamically bot created illusion to force the price down

I think best thing he could do now is to get out off market and fight on another day.
Or then just clean sell side with massive pump.

The Runaway Bride (1999) Reviewed by Eugene Novikov http://www.ultimate-movie.com Member: Online Film Critics Society
*** out of four
Starring Julia Roberts, Richard Gere, Christopher Meloni, Joan Cusack. Rated PG.
If I had to name the most common problems with 90's romantic comedies, at the top of the list would be their inherent implausibility. How and why the characters fall in love is barely ever explained; instead we are expected to trust the old Love at First Sight/I Know She Is the One for Me explanation. Sometimes we aren't given any explanation at all: one scene has the soon-to-be couple bickering, fighting and hating each other and then -- boom -- in the next scene they are passionately kissing.
The reason I warmed up to the new Julia Roberts vehicle, none-too-subtly monikered The Runaway Bride, is that it avoids that most common and most frustrating of problems. This is a film that does not ask us to take a gargantuan leap into suspension of disbelief in order for us to accept its premise. It works not only as a comedy but also as a love story; a compelling romance between two people that have a believable future together.
The Runaway Bride reunites the Pretty Woman dream-team of Julia Roberts and Richard Gere.  Sitting in his favorite bar one day he gets a tip-off of sorts from a fellow sitting next to him: there is a girl in his hometown, he says, who is legendary for ditching grooms at the altar. Ike loves it and decides to write about it. His damning mistake was exaggerating, turning a potentially interesting article into a -- who'd have guessed it -- a bitter diatribe about women and a lie at that.
Maggie Carpenter, the subject of Ike's column/tirade, happens to pick up the paper that day and peruse Mr. Graham's little masterpiece. Lies about her in a national publication don't exactly make her day so she writes a retort to Ike's editor, correcting the 15 -- count 'em -- 15 factual errors he made. The editor (coincidentally his ex-wife) fires him. His friend makes the down-on-his-luck Graham this offer: if he goes to Maggie's hometown and Maggie, currently engaged for the fourth time, runs from the altar again, he gets a cover story in GQ magazine.
Our merry journalist does go to Maggie's hometown and meets Maggie as well some of the colorful characters in her life. There's Peggy, Maggie's sympathetic, supportive friend (played by my favorite actress, Joan Cusack); her stereotypically spunky grandmother, and of course her husband-to-be Coach Bob (Christopher Meloni). Bob is a nice enough guy but Ike can't help but wonder whether he is right for Maggie and more importantly whether he himself has feelings for the legendary Runaway Bride.
The romance that inevitably blooms between Maggie and Ike is, for once, palpable and tangible. They fall in love like real people would. There is no suddenness; the romance develops gradually and believably. We can see not only that they have fallen for each other but also that they can live together for many happy years.
Julia Roberts looks luminously young as Ms. Carpenter and her performance works just as well as her makeup.  She pulls her role off with impeccable precision, making us believe that Maggie is a complex adult with real issues as opposed to an indecisive airhead who has ruined many a life with her irresponsible choices. Richard Gere is a bit too sarcastic and impersonal in the first 2/3 of The Runaway Bride but finishes off strong to make his performance a success. And what can I say about Joan Cusack? One of the best working actresses, she is in top form: her performance is fine-tuned and hilarious even though her role is underwritten.
The Runaway Bride likewise benefits from top-notch comic timing. Director Gary Marshall gives his film an even, rhythmic pace and disperses enough delightful gags to make the movie a good comedy in addition to being an exceptional love story.
Like most romantic comedies, this one doesn't say anything exceptionally daring or resonant, but that doesn't prevent it from being a terrific movie. The Runaway Bride is a standout because the romance at its core seems like a real one. In addition to laughing at what we see, we believe it too. That has become so rare in modern movies that The Runaway Bride should be cherished. ©1999 Eugene Novikov

Crashing Robots
问题描述 :
In a modernized warehouse, robots are used to fetch the goods. Careful planning is needed to ensure that the robots reach their destinations without crashing into each other. Of course, all warehouses are rectangular, and all robots occupy a circular floor space with a diameter of 1 meter. Assume there are N robots, numbered from 1 through N. You will get to know the position and orientation of each robot, and all the instructions, which are carefully (and mindlessly) followed by the robots. Instructions are processed in the order they come. No two robots move simultaneously; a robot always completes its move before the next one starts moving.
A robot crashes with a wall if it attempts to move outside the area of the warehouse, and two robots crash with each other if they ever try to occupy the same spot.
A robot crashes with a wall if it attempts to move outside the area of the warehouse, and two robots crash with each other if they ever try to occupy the same spot.
输入:
The first line of input is K, the number of test cases. Each test case starts with one line consisting of two integers, 1 <= A, B <= 100, giving the size of the warehouse in meters. A is the length in the EW-direction, and B in the NS-direction.
The second line contains two integers, 1 <= N, M <= 100, denoting the numbers of robots and instructions respectively.
Then follow N lines with two integers, 1 <= Xi <= A, 1 <= Yi <= B and one letter (N, S, E or W), giving the starting position and direction of each robot, in order from 1 through N. No two robots start at the same position.
Figure 1: The starting positions of the robots in the sample warehouse
Finally there are M lines, giving the instructions in sequential order.
An instruction has the following format:
< robot #> < action> < repeat>

Where
- L: turn left 90 degrees,
- R: turn right 90 degrees, or
- F: move forward one meter,
and 1 <= < repeat> <= 100 is the number of times the robot should perform this single move.
输出:
Output one line for each test case:
- Robot i crashes into the wall, if robot i crashes into a wall. (A robot crashes into a wall if Xi = 0, Xi = A + 1, Yi = 0 or Yi = B + 1.)
- Robot i crashes into robot j, if robots i and j crash, and i is the moving robot.
- OK, if no crashing occurs.
Only the first crash is to be reported.

Javier Hernandez (Chicharito) - The little Pea
A picture of Chicharito in Action for ManUtd
A tribute to our Favourite Manchester United Player, Chicharito: Hernández was born in Guadalajara, Jalisco and first played in a recreation league when he was seven years old. Hernández lived in Morelia, Michoacán for over four years while his father, footballer Javier "Chícharo" Hernández, played for Monarcas Morelia.[5] While living in Morelia, Hernández attended elementary school at the Instituto Piaget where he studied from third to sixth grade and played for the school's football team.[5] At the age of nine, Hernández joined C.D. Guadalajara and signed his first professional contract when he was 15.[6] He was set to play in the 2005 FIFA U-17 World Championship, but an injury sidelined him from the team that ultimately won the championship.[7] Whilst playing football professionally, Hernández was also taking business administration classes at Universidad del Valle de Atemajac.[6] Hernández has held both Hugo Sánchez and Rafael Márquez as his football idols growing up.

Particle Pixel Collision
2006 March 26th by todd anderson
Well, i said i was gonna get into switching action policies for the user-controlled sprite, but i thought it might be cool if i gave a visual clue if the sprite was disabled ( unable to switch actions ). Then i thought, ‘What better clue than a ring of stars around its head?’. Created a rotating-ring particle system. Done…
Damn… It rotates, but not around the sprite. I’ve been placing particle systems in their own movieclip – somtimes behind, sometimes atop the sprite… I wasn’t rendering everything in a ‘world’ view with z-buffering, because everything was 2d and i thought ‘…just layer it, jerk’. i still do.
Let’s see… do i throw a particle system in with the sprite class and swap depths based on z position of particles? No i just want a sprite to be a sprite and not worry about managing anything. Should i have a special particle system that sandwiches movieclips around the emission node, then create and dipose based on z-position? Now with AS3, i could fashion something like that because of the DisplayList ( as Sam so eloquiantly showed… though i he didn’t strip off an article clothing after every audience question – which was promised ), but in AS2 that would just be too confusing.
So i went back to my PixelCollision class and decided to poke around. Well, i did… and royally screwed up that code (that’s what svn is for!), but came out with a nice solution for replacing pixels in one bitmapdata object based on non-alpha collisions.
In the movie link above you can see what’s happening (well kind of, i made it too small i think). It’s actually a rotating-ring system in a layer above the sprite, and it’s applying alpha transparency to the stars based on collision – and/or also pixel replacement of sprite if you click on the stage (that’s my favorite part). It’s a shame it gets a little skippish in a browser, i’ll have to do a little cleaning and see what happens.

It's been a minute since my last post and also since the last time I wrote Ruby for a living. After a five-month-or-so React Native binge, I'm back on the Rails, and wow, I literally typed const
yesterday when defining a variable. By which I mean it's going great, how are you?
So understandably, I was really excited when a coworker of mine at Home Chef started a casual book club-style reading of 99 Bottles of OOP by Sandi Metz and Katrina Owen. Not that I've been far from OOP in Reactville, but the book goes through a lot of useful principles of refactoring, naming, increasing flexibility, and other things I didn't have much time to ponder when I was busy churning out mobile apps on rush deadlines —in Ruby!
We recently finished the starting exercise as well as the first chapter, and here are some first impressions / takeaways / quotes I really liked.
Writing code is like writing a book; your efforts are for other readers.
I could not agree more! Partly, I think this is why my editing background keeps coming to bear in my coding life. Questions of audience and readability are still incredibly relevant, and I will continue to shout them from the rooftops.
DRY promises that if you put a chunk of code into a method and then invoke that method instead of duplicating the code, you will save money later if the behavior of that chunk changes. Recognize, though, that DRYing out code is not free. It adds a level of indirection, and layers of indirection make the details of what's happening harder to understand.
Recognizing that the SOLID principles and other tenets of programming are the result of cost-benefit analysis is super valuable. Too many "rules" out there are blindly followed without understanding the critical thinking behind them, and sometimes mis-applying those rules can result in code that is more convoluted than when you started. I'm certainly not advocating that DRY code isn't better than "wet" code, but stopping to ask yourself why that's true is a good use of your brain.
Again, we're always thinking about who is going to come along and read our code after we've moved on to some other problem.
As programmers grow, they … become comfortable with complexity. This higher level of comfort sometimes leads to the belief that complexity is inevitable … [but] infinitely experienced programmers do not write infinitely complex code; they write code that’s blindingly simple.
I love this. I love it so much. One of the things writers and editors learn as they grow, too, is how often cleverness can obscure meaning. It can manifest as "this word, I do not think it means what you think it means" syndrome, or as long and convoluted sentence structure that's hard to follow. (I used to think of this as "where is the subject and where is the verb?" syndrome.) Code can come in these same flavors, and us juniors sometimes start to think of complex code as being written by someone "better" than us — when really it's the simple code that's hardest to write.
Hopefully this summary of Chapter One was interesting, and you're inspired to pick up a copy of 99 Bottles of OOP for yourselves. I'm really looking forward to diving into the practical chapters on refactoring and arriving at that "blinding" simplicity myself. I might even let you know what I find out. Happy reading!


The book Parallel Program Design: A Foundation by Chandy and Misra (Addison-Wesley, 1988) presents the UNITY formalism. UNITY consists of an abstract programming language of guarded assignments and a calculus for reasoning about such programs. Misra's 1994 paper "A Logic for Concurrent Programming" presents New UNITY, giving more elegant foundations for a more general class of languages. In recent work, Chandy and Sanders have proposed new methods for reasoning about systems composed of many components.
This directory formalizes these new ideas for UNITY. The Isabelle examples may seem strange to UNITY traditionalists. Hand UNITY proofs tend to be written in the forwards direction, as in informal mathematics, while Isabelle works best in a backwards (goal-directed) style. Programs are expressed as sets of commands, where each command is a relation on states. Quantification over commands using [] is easily expressed. At present, there are no examples of quantification using ||.
A UNITY assertion denotes the set of programs satisfying it, as in the propositions-as-types paradigm. The resulting style is readable if unconventional.
Safety proofs (invariants) are often proved automatically. Progress proofs involving ENSURES can sometimes be proved automatically. The level of automation appears to be about the same as in HOL-UNITY by Flemming Andersen et al.
The directory Simple
presents a few examples, mostly taken from Misra's 1994
paper, involving single programs.
The directory Comp
presents examples of proofs involving program composition.

- Login
- Create new repository ‘mytestrepo’ or click on homework link to automatically create your homework repository for the specific assignment
- Add a README.md file. This ends in ‘md’ because we usually write these in markdown which is a structured text format that can be rendered in nice ways in HTML and PDF (like this guide). You can also make it a plain text file and use ‘.txt’.
- Upload files to the repository online.
- Checkout the code.
$ git clone https://github.com/YOURID/mytestrepo.git
- Edit / Update a file
$ nano solution.sh
# or some other tool (e.g. emacs, textedit, vi, ...)
- Commit these changes to your LOCAL repository
$ git commit -m "I updated the solution"
- Save this changed repository in the github server. (eg ‘the cloud’). This lets others see the file changes and sync their repository with yours if you are doing a collaborative project or for the instructor to see your submitted solutions. Also saves a copy, you or others can then checkout a clone of this repository on other computers or even just different folders if you need to
$ git push
# git push will request your github ID and github password
- Add another new file (e.g. another script)
$ nano newfile.py
$ git add newfile.py
$ git commit -m "I added this new file" newfile.py

jemdoc – example page
Example
Here are some text features. I could link somewhere or insert a raw link to another page like download.html. I could use monospace, too. I could write special characters like #, $ and + by just using a backslash (\) in front of those characters. Or automatically detect an email address.
Save the file as index.jemdoc, say, and simply call jemdoc index (after downloading jemdoc, of course).

(
- It is extremely hard to learn a model of the world without experiencing “enough examples”, so the data is still extremely necessary.
-
To capture an entire distribution over some data that should GENERALIZE well; is limited by how actually representative that data is of the true “data-generating” distribution, so “good” data is necessary )
- Hypothesis: Deep CNNs have a tendency to learn superficial statistical regularities in the dataset rather than high level abstract concepts.
- From the perspective of learning high level abstractions, Fourier image statistics can be superficial regularities, not changing object category.
- So long as our machine learning models cheat, by relying only on superfcial statistical regularities, they remain vulnerable to out-of-distribution examples.
- Humans generalize better than other animals thanks to a more accurate internal model of the underlying causal relationships.
The need for predictive causal modeling: rare & dangerous states:
- Autonomous vehicles in near- accident situations.
- Current supervised learning fails these cases because they are too rare.
- Worse with RL (statistical inefficiency)
- Goal: develop better predictive models of the world able to generalize in completely unseen scenarios, but it does not seem reasonable to model the sequence of future states in all their details.
- (Without) No need to die a thousand deaths
Motivation:
- As we are deploying Machine Learning in the real world, what happens is that, the kind of data on which those systems will be used, is almost for sure are going to be statistically different from the kind of data on which it was trained.
- And as an example of this consider self driving cars or vehicles, for which would like them to behave well in these rare but dangerous states.
Invariance vs Disentangling:
- They are different concepts.
- Invariance: is a property of an object/system being equal wrt. a certain change.
We seek to have invariant detectors, features, etc. to certain things we care about; but sensitive to other things (based on the domain). - Disentangling:
- Motivation:
- But if we’re trying to explain the world around us, if we’re trying to build machines that explain the world around them that understand their environment, we should be prudent about what aspects of the world we would like our systems to be invariant about. Maybe we want to capture everything.
And the most important aspect isn’t what we get rid of or not, but rather how we can separate the different factors from each other. - It helps us deal with curse of dimensionality.
- But if we’re trying to explain the world around us, if we’re trying to build machines that explain the world around them that understand their environment, we should be prudent about what aspects of the world we would like our systems to be invariant about. Maybe we want to capture everything.

Good Representations (Bengio)
The idea is when we transform the data in the space, machine learning becomes easier.
So, in particular, the kind of complex dependencies that we see in them, say, the pixel space will become easy to model maybe with linear models or factorize models in that space. - Latent Variables and Abstract Representations
- Encoder/decoder view: maps between low \(\&\) high-levels
- Encoder does inference: interpret the data at the abstract level
- Decoder can generate new configurations
- Encoder flattens and disentangles the data manifold
Go from a “spaghetti” of manifolds to, flat and separate manifolds.- A big goal is: transform the “curved” (data) manifold, into a flat manifold.
- Checking that a manifold is flat:
Simple Idea: Interpolate between two points on the manifold (average), if the middle point comes from the data distribution (e.g. image), then it is flat.- Interpolating in h-space should give you e.g. either one image or the other, but not a blend (preserve identity).
- Interpolating in X-space will give you e.g. a combination of the two images.
- A big goal is: transform the “curved” (data) manifold, into a flat manifold.
- Marginal independence in h-space
- What’s missing in DL:
Deep Understanding. - What is needed:
- Generalizing Beyond i.i.d. Data:
- The Learning Theories need to be modified.
- Current ML theory is strongly dependent on the iid assumption
- Real-life applications often require generalizations in regimes not seen during training
- Humans can project themselves in situations they have never been (e.g. imagine being on another planet, or going through exceptional events like in many movies)
- Solution: understanding explanatory/causal factors and mechanisms.
- How: Clues to help disentangle the underlaying causal factors (w/ regularization).
- Generalizing Beyond i.i.d. Data:
- Humans Outperform Machines at Autonomous Learning:
- Humans are very good at unsupervised learning, e.g. a 2 year old knows intuitive physics
- Babies construct an approximate but sufficiently reliable model of physics.
- How do they manage that?
Note that they interact with the world, not just observe it.- It is important to act in the world to acquire information.
The basic tools for that come from RL.
It is not developed enough, as of now.Note: the information gained/learned by an acting agent is subjective to his own capabilities/affordences.
E.g. Adult vs Baby (bodies) interacting with the world.
- It is important to act in the world to acquire information.
- How do they manage that?


Silicon Valley and the tech industry has always attracted the dreamers. Men and women equipped with words that entice and invoke a vision in others are often lauded as saviors and world-changers. It's also a modern-day outlet for entrepreneurs, who in former centuries, would have been empire builders and saavy generals.
The media certainly doesn't help to keep the hype under control. On the contrary, the media feeds it. They want rocketships - companies that blow up. But this attracts attention-craving, egotistical entrepreneurs who, with only a good idea, but with poor character and ability to execute, can have moments in the limelight, but often blow up as fast as they started.
One of the biggest problems of the tech world is the hubris, the greed, and the lack of transparency that comes with it all. Oversold and under-delivered, often times, it becomes hard to distinguish fact from fiction. For every company that succeeds and successfully exits, whether through IPO or acquisition, dozens more fail.Clinkle, Better Place, and Fab come to mind as well-documented failures recently. Wasted venture capital ranges from $50 million to over $500 million within these 3 examples alone. Although the product and the vision are often different, those that fail usually have the same story.
Here's the story in 10 steps: 1. A Steve Job-esque founder with a great idea captivates VCs and employees alike. 2. A big round of funding is raised and strategic hires are made. Media hype ensues. 3a. No viable product is available, no market fit, no long-term strategy towards profitability. 4. Continue to hire positions that are not needed. Hire friends and family but never someone with the right experience. 5. Excessively spend money on lavish set-ups, offices, and other amenities but never the product. 6. There's now a minimally viable product but no market fit. 7. Employees start wondering what's going on. The co-founder bullshits his/her way into keeping everyone around longer. Everything looks good and the future is bright. 8. Key employees in the C-Level start to leave. 9. Employees stop trusting the founder and rumors start about the diminishing runway the company has. 10. Everyone realizes it's a phony company. Millions of VC funding and dozens of people's lives are devastated.
There aren't very many solutions that I can offer having never run a start-up. Additionally, many of these are structural and institutionalized within the systems of the tech world. However, I've established a mindset as I look for potential employers.Ask hard questions during the latter half of the interview. If they're transparent then, they'll be transparent later. 1. Is there a business model? What's the product market fit? What's the plan for profitability? What's the competition like? 2. Does the founder have great credentials? PHD or Masters degree from a top university? Have they successfully started a company before? I might miss out on the next Mark Zuckerberg but I think I'll hit more than I miss. 3. Would the founders be good parents? Could you trust them? Are they reliable? Do they make sacrifices for the company? Or is it all about their ego and success? 4. Do they care about the customer? Are they devoting resources to product and engineering to please customers, reduce churn, and build a long-term business? Or is it only sales/marketing with very little product?
My belief is that you learn just as much from these failures as you do successes. And often times, the story of the successes are often undocumented or maybe under-documented by the media. Success often looks boring: hiring the person with the right skillset instead of the bloated resume, deciding to tell your company the truth when it's difficult to do so, and on and on. Ben Horowitz, the famous venture capitalist, wrote a book called, "The Hard Thing About Hard Things", highlighting the seemingly miniscule decisions made in pressure-packed moments that often define a companies trajectory. These require immense character, boldness, and resolve and therefore should be documented. But they're often not spoken about and this leaves room for failure stories. After all, everyone likes a crash and burn story.


The Windows AT command is sort of a second rate citizen compared to schtasks. It can also schedule tasks to run at specific times but does not have nearly as many configuration options.
One thing to keep in mind is that the AT command always runs with SYSTEM level privileges. Several usage examples can be seen below.

Every year thousands of fans fill Chessa and Pruitt fields, Peden Stadium and The Convo to see Ohio’s fall sports programs compete in their respective sports. Each season comes with games and events that Bobcat fans don’t want to miss. Here are a few to look out for, complete with tentative start times and dates (for the complete fall schedule check out the Ohio Bobcats athletic homepage).
Lauren Bacho | FILE
Sebastian Smith, Ohio junior wide receiver, runs the ball during the Ohio vs Miami homecoming game on October 10, 2015. Ohio beat Miami 34-3.
Ohio v. Miami (Football), Oct. 31, Kickoff TBA
The annual “Battle of the Bricks” returns to Peden Stadium this year, and it’s definitely
an event that the Bobcat faithful show out for in full force. Last season the Bobcats stole the game from the RedHawks and won 17-7 in Oxford. After last season’s game that featured only 435 combined total yards, this year will be sure to feature another chippy game against Ohio’s most notorious rival. Coincidentally, this game also follows HallOUweekend, so any Miami friends you have might just sleep in your dorm room or apartment for an extended stay.
Ohio v. Central Michigan (Football), Oct. 7, Kickoff TBA
Another word in which I can insert “OU” and have it still make sense: hOUmecoming. The
Bobcats will look to give Ohio alumni the gift of victory as they play Central Michigan. Ohio dropped last year’s bout against Central Michigan, 27-20. Nonetheless, this year Ohio looks to exact revenge on its own turf in front of Bobcats both old and new.
Bobcat Invitational (Volleyball), Sept. 1-2, All Day
The Bobcats volleyball team hosts the Bobcat Invitational this year, which will bring
Power 5 schools Oklahoma and Georgia to campus. Fun fact: OU comes to OU, and the University of Georgia is in Athens, Georgia. Last season, Ohio traveled to Norman, Oklahoma, to participate in the NIKE Invitational, an invitational that didn’t go so hot for the Bobcats, who went 1-2 at the invitational. But that was then and this is now. A young, inexperienced team took the court last year but showed promise towards the end of the year.
Ohio v Eastern Michigan (Soccer), Sept. 22, 4 p.m.
The pitch at Chessa Field on Ohio’s athletic side of campus (on West Green) saw many games in the 2016-17 campaign that were close all the way to the end but fell the other way, resulting in a Bobcat loss. After going 3-8 in conference play last season, the Bobcats look to start on the right foot (or left, depending on who’s dribbling) in their Mid-American Conference home/season opener against the Eagles of Eastern Michigan. After dropping last season’s bout 2-0 in Ypsilanti, the Bobcats will look to be on the other end of those close games, with more offensive production in the first half and sharper defense in the closing minutes of the match.
Ohio v Miami, Ohio v Bowling Green (Volleyball), Sept. 29-30, 7 p.m. (both days)
While the team starts conference play on the road (against Buffalo and Akron), Ohio opens up home conference play against in-state rivals Miami and Bowling Green. Starting off with Miami on the 29th, Ohio returns a more experienced team for this season. Looking to avenge a 3-0 shutout in Oxford last season, the Bobcats bring back all the tools necessary to steal a win against the MAC Tournament runner-up. The next day, the Falcons swept into Athens looking to do what the Bobcats will try to do against the RedHawks: exact revenge. With a 3-0 win over Bowling Green last season in the Stroh Center, it’ll be sure to make for a good contest between both Ohio MAC schools.
Ohio v Kansas (Football), Sept. 16, Kickoff 2 p.m.
If you’ve ever wanted to see a Big 12 school play a football game but never have wanted to go out west, you’re in luck. The Kansas Jayhawks come to Athens in mid-September in a Power 5 versus Group 5 Division I football game. Last season the Bobcats took a trip to Memorial Stadium in Lawrence, Kansas, and waltzed away with a victory behind former quarterback Greg Windham's stellar performance. Traditionally, Kansas isn’t one of the most dominant football programs in the country, but it is a member of one of the most historically talented conferences in the Big 12. With a 2 p.m. kickoff, there’s more than enough of a Saturday to hang out at Peden Stadium and still have a night out in Athens.
Ohio v Toledo (Soccer), Oct. 22, 1 p.m.
For the seven seniors on the Bobcats soccer team, this will be their last match at Chessa Field. A close game ensued last season between the two teams at Lynn Stadium in Toledo. With a 1-1 tie at halftime, the Bobcats couldn’t find a way to put one in the back of the net. Toledo, however, did and ultimately won the match 2-1. But with seven seniors on the pitch at one time, a collective experience and chemistry could get Ohio some wins this season, including against Toledo.
Ohio v Toledo (Football), Nov. 8, Kickoff TBA
Much like the soccer team, last season the Bobcats were in a close game with Toledo. The difference being that the Bobcats came out on top and won 31-26. This season 18 seniors will sport the green and white one last time in Peden Stadium. With an 8-6 record last season, the Bobcats are looking to once again make an appearance in the MAC Championship Game come December.
Ohio v Central Michigan (Volleyball), Sept. 11, 7 p.m.
Though the Bobcats are still a young team, that doesn’t mean they don’t come without experience. Yet, they have only one senior on the team: Ali Lake, a middle-backer from Liberty Township. Lake, a redshirt senior, has spent the last five years playing for the Bobcats and has gone through the ups and downs that are typical in collegiate volleyball. Last season the Bobcats lost 3-2 against the Chippewas in a close match in each set. With all of that youth returning, the Bobcats have the potential to compete with anyone in the conference this season.
Editor’s Note: The Field Hockey, Hockey, Cross Country, Golf teams had not released their schedules as of press time.

Setting up Rails Apps with Passenger and Nginx in Debian, Ruby, Rails, Nginx
Deploy Rails Apps with Passenger and Nginx - Debian
Difficulty: 2
Time: 30 minutes
Rails enables rapid application development, while NGINX is a lightweight and high performance web server. In this article, you will learn to deploy Rails application on NGINX web server using the simple and powerful features of Phusion Passenger. To perform this task, its is assumed that the user has sudo privileges.
Prerequisites
Install NGINX and Passenger
- Update the repositories and install the dependencies for Ruby and NGINX.
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
- Add the
gpg
key and install the Phusion Passenger.
gpg --keyserver keyserver.debian.com --recv-keys 561F9B9CAC40B2F7
gpg --armor --export 561F9B9CAC40B2F7 | sudo apt-key add -
sudo apt-get install apt-transport-https
- Add the Passenger repository in the source list.
sudo sh -c "echo 'deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main' >> /etc/apt/sources.list.d/passenger.list"
sudo chown root: /etc/apt/sources.list.d/passenger.list
sudo chmod 600 /etc/apt/sources.list.d/passenger.list
sudo apt-get update
- Install NGINX and Passenger.
sudo apt-get install nginx-full passenger
- For language, select
Ruby
, and then press the Enter key.
Use <space> to select. If the menu doesn't display correctly, ensure that your terminal supports UTF-8.
- Ruby
- Python
- Node.js
- Meteor
- Select
1
and press the Enter key to continue. This action downloads, compiles, and installs the NGINX files with Passenger support.
1. Yes: download, compile and install Nginx for me.(recommended)
The easiest way to get started. A stock NGINX 1.4.4 with Passenger support, but with no other additional third party modules, will be installed for you to a directory of your choice.
Set up a Test Rails Application
- Create a directory.
sudo mkdir -p /var/www
- Move to the
www
directory, and create a Rails application.
cd /var/www
rails new SampleApp
cd SampleApp
- Create sample resources.
rails generate scaffold Task title:string note:text
rake db:migrate RAILS_ENV=development
- To test your application, run the following command in application directory:
rails s --bind=Public-IP
Configure NGINX
- Open the following configuration file of NGINX.
sudo vim /etc/nginx/nginx.conf
-
Uncomment the following line:
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/deploy/.rbenv/shims/ruby; # If you use rbenv
- Save and Exit.
:wq
- Restart the NGINX service.
sudo service nginx restart
- Open the following configuration file to configure host
/etc/nginx/sites-enabled/default
:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
server_name www.coolexample.com; // Replace coolexample.com witch FQDN or Public-IP
passenger_enabled on;
rails_env production;
root /var/www/SampleApp/public; // Your rails application's path
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
- Save and Exit.
:wq
- Restart the NGINX service.
sudo service nginx restart
Conclusion
In this article, we reviewed the steps involved in installing Ruby on Rails using RVM, installed NGINX and Passenger, and finally compiled and configured it to deploy our Rails application on NGINX web server.
