vdist
(lat1, lon1, lat2, lon2)[source]¶ Using the WGS-84 Earth ellipsoid, compute the distance between two points within a few millimeters of accuracy, compute forward azimuth, and compute backward azimuth, all using a vectorized version of Vincenty’s algorithm:
s = vdist(lat1,lon1,lat2,lon2) s,a12 = vdist(lat1,lon1,lat2,lon2) s,a12,a21 = vdist(lat1,lon1,lat2,lon2)
- s
- distance in meters (inputs may be scalars, vectors, or matrices)
- a12
- azimuth in degrees from first point to second point (forward)
- a21
- azimuth in degrees from second point to first point (backward)
(Azimuths are in degrees clockwise from north.)
- lat1
- GEODETIC latitude of first point (degrees)
- lon1

Original algorithm source: T. Vincenty, “Direct and Inverse Solutions of Geodesics on the Ellipsoid with Application of Nested Equations”, Survey Review, vol. 23, no. 176, April 1975, pp 88-93. Available at: http://www.ngs.noaa.gov/PUBS_LIB/inverse.pdf

lat1,lon1,lat2,lon2 can be any (identical) size/shape. Outputs will have the same size and shape.
Error correcting code, convergence failure traps, antipodal corrections, polar error corrections, WGS84 ellipsoid parameters, testing, and comments: Michael Kleder, 2004.
Azimuth implementation (including quadrant abiguity resolution) and code vectorization, Michael Kleder, Sep 2005.
Vectorization is convergence sensitive; that is, quantities which have already converged to within tolerance are not recomputed during subsequent iterations (while other quantities are still converging).
Vincenty describes his distance algorithm as precise to within 0.01 millimeters, subject to the ellipsoidal model.
For distance calculations, essentially antipodal points are treated as exactly antipodal, potentially reducing accuracy slightly.
Distance failures for points exactly at the poles are eliminated by moving the points by 0.6 millimeters.
The Vincenty distance algorithm was transcribed verbatim by Peter Cederholm, August 12, 2003. It was modified and translated to English by Michael Kleder. Mr. Cederholm’s website is http://www.plan.aau.dk/~pce/
Distances agree with the Mapping Toolbox, version 2.2 (R14SP3) with a max relative difference of about 5e-9, except when the two points are nearly antipodal, and except when one point is near the equator and the two longitudes are nearly 180 degrees apart. This function (vdist) is more accurate in such cases. For example, note this difference (as of this writing):
vdist(0.2,305,15,125)
> 18322827.0131551
distance(0.2,305,15,125,[6378137 0.08181919])
> 0
Azimuths FROM the north pole (either forward starting at the north pole or backward when ending at the north pole) are set to 180 degrees by convention. Azimuths FROM the south pole are set to 0 degrees by convention.
Azimuths agree with the Mapping Toolbox, version 2.2 (R14SP3) to within about a hundred-thousandth of a degree, except when traversing to or from a pole, where the convention for this function is described in (10), and except in the cases noted above in (9).

pymap3d.vincenty.
vreckon
(lat1, lon1, rng, azim, ellipsoid=None)[source]¶ Computes points at a specified azimuth and range in an ellipsoidal earth. Using the WGS-84 Earth ellipsoid, travel a given distance along a given azimuth starting at a given initial point, and return the endpoint within a few millimeters of accuracy, using Vincenty’s algorithm.
USAGE:
lat2,lon2 = vreckon(lat1, lon1, rng, azim)
Transmits ellipsoid definition (either as [a,b] or [a,f]) as fifth argument ELLIPSOID
VARIABLES
- lat1
- inital latitude (degrees)
- lon1
- initial longitude (degrees)
- rng
- distance (meters). Scalar or a vector. Latter case computes a series of circles (or arc circles, see azim) centered on X,Y (which are scalars)
- azim
- intial azimuth (degrees). “azim” is a scalar or vector
- ellipsoid
- two-element ellipsoid vector. Either [a b] or [a f] If omitted, defaults to WGS-84
- lat2, lon2
- second point (degrees)
- a21
- reverse azimuth (degrees), at final point facing back toward the intial point
Original algorithm: - Vincenty, “Direct and Inverse Solutions of Geodesics on the Ellipsoid with Application of Nested Equations”, Survey Review, vol. 23, no. 176, April 1975, pp 88-93. http://www.ngs.noaa.gov/PUBS_LIB/inverse.pdf
Notes:
- The Vincenty reckoning algorithm was transcribed verbatim into JavaScript by Chris Veness. It was modified and translated to Matlab by Michael Kleder. Mr. Veness’s website is: http://www.movable-type.co.uk/scripts/latlong-vincenty-direct.html
- Error correcting code, polar error corrections, WGS84 ellipsoid parameters, testing, and comments by Michael Kleder.
- By convention, when starting at a pole, the longitude of the initial point (otherwise meaningless) determines the longitude line along which to traverse, and hence the longitude of the final point.
- The convention noted in (3) above creates a discrepancy with VDIST when the the intial or final point is at a pole. In the VDIST function, when traversing from a pole, the azimuth is 0 when heading away from the south pole and 180 when heading away from the north pole. In contrast, this VRECKON function uses the azimuth as noted in (3) above when traversing away form a pole.
- In testing, where the traversal subtends no more than 178 degrees, this function correctly inverts the VDIST function to within 0.2 millimeters of distance, 5e-10 degrees of forward azimuth, and 5e-10 degrees of reverse azimuth. Precision reduces as test points approach antipodal because the precision of VDIST is reduced for nearly antipodal points. (A warning is given by VDIST.)
- Tested but no warranty. Use at your own risk.

| 1 Geometry Manager Overview
| 1.2 How Geometry Is Managed
The geometry manager, used effectively, can take nearly all the work out of displaying, sizing, and positioning objects on the screen. Many of the tasks you normally would have to do to create even a simple dialog box are taken care of automatically by the geometry manager and the specific UI library. Among the functions the geometry manager performs are the following:
-
Window Positioning and Sizing
The geometry manager interacts directly with the UI to determine where windows should be placed and what their dimensions should be. You have some control over this with hints, messages, and object instance data, and often you will have to choose a hint to determine the window position or size.
-
Object Sizing
The size of an object can be determined by the combined sizes of its children, by the limits of its parent, or specifically by other constraints on the object. The geometry manager allows all three types of sizing behavior. The first two are implemented automatically in geometry updates; the third depends on how the application wants to manage the "other constraints."
-
Object Positioning
The position of an object can be determined either by the object or by the geometry manager. The geometry manager can position objects based on several criteria including the spacing of siblings in a composite, the size and/or location of the parent composite, and the justification hints applied to the object. Visible objects can control very closely how and where they are positioned; generic objects can determine how positioning occurs with various hints.
-
Automatic Geometry Updating
Typically, when a particular object in a tree is resized, repositioned, added, or removed, the object mechanisms will mark the geometry of both that object and its parent invalid. This will invoke the geometry manager, which will traverse the object tree, determine which objects are affected by the potential geometry change, and then update the size and position of all affected objects up to the top of the tree. This entire process is automatic for generic objects; for visual objects, you may or may not have to mark the object invalid yourself, depending on the depth of custom geometry control you use.
 The system does all the dirty work of drawing and managing the objects on the screen, leaving you free to work on your application rather than on its graphical screen representation.

Custom3DItem QML Type
Adds a custom item to a graph. More...
| Import Statement: | import QtDataVisualization 1.2 |
| Since: | QtDataVisualization 1.1 |
| Instantiates: | QCustom3DItem |
| Inherited By: |
Properties
- meshFile : string
- position : vector3d
- positionAbsolute : bool
- rotation : quaternion
- scaling : vector3d
- scalingAbsolute : bool
- shadowCasting : bool
- textureFile : string
- visible : bool
Methods
- void setRotationAxisAndAngle(vector3d axis, real angle)
Detailed Description
A custom item has a custom mesh, position, scaling, rotation, and an optional texture.
Property Documentation
The item mesh file name. The item in the file must be in Wavefront OBJ format and include vertices, normals, and UVs. It also needs to be in triangles.
position : vector3d |
The item position as a vector3d type. Defaults to vector3d(0.0, 0.0, 0.0)
.
Item position is specified either in data coordinates or in absolute coordinates, depending on the value of the positionAbsolute property. When using absolute coordinates, values between -1.0...1.0
are within axis ranges.
Note: Items positioned outside any axis range are not rendered if positionAbsolute is false
, unless the item is a Custom3DVolume that would be partially visible and scalingAbsolute is also false
. In that case, the visible portion of the volume will be rendered.
See also positionAbsolute and scalingAbsolute.
Defines whether item position is to be handled in data coordinates or in absolute coordinates. Defaults to false
. Items with absolute coordinates will always be rendered, whereas items with data coordinates are only rendered if they are within axis ranges.
See also position.
rotation : quaternion |
The item rotation as a quaternion. Defaults to quaternion(0.0, 0.0, 0.0, 0.0)
.
scaling : vector3d |
The item scaling as a vector3d type. Defaults to vector3d(0.1, 0.1, 0.1)
.
Item scaling is specified either in data values or in absolute values, depending on the value of the scalingAbsolute property. The default vector interpreted as absolute values sets the item to 10% of the height of the graph, provided the item mesh is normalized and the graph aspect ratios have not been changed from the defaults.
See also scalingAbsolute.
Defines whether item scaling is to be handled in data values or in absolute values. Defaults to true
. Items with absolute scaling will be rendered at the same size, regardless of axis ranges. Items with data scaling will change their apparent size according to the axis ranges. If positionAbsolute is true
, this property is ignored and scaling is interpreted as an absolute value. If the item has rotation, the data scaling is calculated on the unrotated item. Similarly, for Custom3DVolume items, the range clipping is calculated on the unrotated item.
Note: Only absolute scaling is supported for Custom3DLabel items or for custom items used in polar graphs.
Note: The custom item's mesh must be normalized to the range [-1 ,1]
, or the data scaling will not be accurate.
This QML property was introduced in QtDataVisualization 1.2.
See also scaling and positionAbsolute.
Defines whether shadow casting for the item is enabled. Defaults to true
. If false
, the item does not cast shadows regardless of ShadowQuality.
The texture file name for the item. If left unset, a solid gray texture will be used.
Note: To conserve memory, the QImage loaded from the file is cleared after a texture is created.
Method Documentation
void setRotationAxisAndAngle(vector3d axis, real angle) |
A convenience function to construct the rotation quaternion from axis and angle.
See also rotation.

Customer Notes: Add maple syrup to the side


In this exercise, you'll use jQuery's $.ajax()
function to pull in a JSON file and turn it into DOM, using the same functions as we did for the in-page JSON.
The Setup
Firefox users only: you can skip this section.
Chrome has a permissions policy for local file://
testing that disallows AJAX requests, and some APIs do not work on file://
URLs in all browsers, so if possible, we recommend trying to run a simple server on your machine. The following steps should work on a Mac:
- Open Terminal
- Navigate to your project directory (wherever you will save the files) by using the
cd
command. - Run this command:
python -m SimpleHTTPServer
- If successful, you should then be able to access your project folder by typing
this URL in the browser bar:
http://localhost:8000
If you are not on a Mac or can't do that for some reason, then we recommend using Firefox or pairing with someone who can run a local server.
To stop the server: go into your Terminal window and hit Control + C
Coding
Go through these steps, and do as many as you can in the time we have:
- Start with your solution from the last exercise, use the completed version (in the solutions folder).
- The webpage currently has an in-page JSON describing the videos, and we want to put that into a separate file. Make a file in your project folder called videos.json, and copy the value of the videos variable into that file. Delete the variable from the page.
- Use the jQuery $.ajax function to bring in the data from videos.json. In the success callback, iterate through the videos and render each one into the page, using the addVideoToList function that we already have. Look at the slides and the jQuery documentation to remember how to use the $.ajax function.
- Bonus: Create another JSON file with another set of videos, and bring that into the page as well. Try to generalize your code so that you could bring any number of JSON files in.
Make sure that you use your browser developer tools to make debugging easier while working on this. Check for errors, and use console.log() to figure out how far your code makes it, and what the values of your variables are along the way.

Range editors
allow users to edit numeric values with ease.

This week, I engraved a coaster, laser cut a waterbottle, and cut a vinyl record to serve as the base of my clock. To address my difficulties from the previous week of designing and execution within the alotted time, I decided to spend the second day of the rotation completing the coaster, which I knew would take less time to design and cut in class. In addition to knowing when and how to use rasters or vectors, designing the record was difficult because importing images often leads to entire chunks being fully removed unless you remove certain segments of a line. On the first day of the rotation, each of the few images I attempted to import were no good, and began working on the coaster. This gave me more time to think of design ideas for the record and watch my peers tackle the process themselves.

Introduction
-
- The Perceptron:
- The Perceptron is an algorithm for supervised learning of binary classifiers.
-
- Type:
- It is a type of linear classifiers.
-
- The Problem Setup:
- Consider \(n\) sample points \(X_1, X_2, ..., X_n\).
- For each sample point, let \({\displaystyle y_i = {\begin{cases} \:\: 1&{\text{if }}\ X_i \in C \\-1&{\text{if}}\ X_i \notin C\end{cases}}}\)
-
where ‘C’ is a given class of interest.
The Perceptron Method
-
- Goal:
- Find weights ‘\(w\)’ such that: \({\displaystyle {\begin{cases}X_i \cdot w \geq 0&{\text{if }}\ y_i = 1\\X_i \cdot w \leq 0&{\text{if }}\ y_i = -1\end{cases}}}\)
-
Where \(X_i \cdot w\) is the signed distance.
- Equivalently:
- \[y_iX_i \cdot w \geq 0\]
-
Where \(y_iX_i \cdot w \geq 0\) is a constraint on the problem.
-
- Procedure:
- Compute the point of greatest descent until you find a local minima and update the weights using “Gradient Descent”.
-
- Decision Function:
- \[{\displaystyle f(x)={\begin{cases}1&{\text{if }}\ w\cdot X_i+\alpha>0\\0&{\text{otherwise}}\end{cases}}}\]
- where \(\alpha\) is added by The fictitious Diminsion Trick
-
- Loss Function:
- \[{\displaystyle L(z, y_i) = {\begin{cases}0&{\text{if }}\ y_i\cdot z_i \geq 0\\-y_i z&{\text{otherwise}}\end{cases}}}\]
-
- Objective (cost) Function:
- \[R(w) = \sum_{i=1}^n L(X_i \cdot w, y_i) = \sum_{i \in V} -y_iX_i \cdot w\]
-
where \(V\) is the set of indices \(i\) for which \(y_iX_i \cdot w < 0\).
- Risk func is Convex but Non-Smooth?
-
- Constraints:
- \[y_iX_i \cdot w \geq 0\]
-
- The Optimization Problem:
- Find weights \(w\) that minimizes \(R(w)\).
-
- Optimization Methods:
- The Perceptron algorithm uses a numerical optimization method.
- Gradient Descent is the most commonly used method.
- Newtons Method can also be used to optimize the objective.
-
- The Gradient Descent Step:
- \[\begin{align} \nabla_w R(w) & \ = \\ & \ = \nabla_w \sum_{i=1}^n L(X_i \cdot w, y_i) \\ & \ = \nabla_w \sum_{i \in V} -y_iX_i \cdot w \\ & \ = \sum_{i \in V} -y_iX_i \end{align}\]
-
- The Algorithm (Frank Rosenblatt, 1957):
- (1) Choose the weights \(\vec{w}\) arbitrarily.
- (2) While \(R(\vec{w}) > 0\):
\(\:\:\:\:\:\:\:\) (3) \(V \leftarrow\) set of indices such that: \(y_iX_i \cdot w < 0\)
\(\:\:\:\:\:\:\:\) (4) \(w \leftarrow w + \epsilon \cdot \sum_{i \in V} y_iX_i \;\;\;\;\;\;\) [GD]
\(\:\:\:\:\:\:\:\) (4) \(w \leftarrow w + \epsilon \cdot y_iX_i \;\;\;\;\;\;\) [SGD] - (5) Recurse
-
- Avoiding the constriction of the separating hyperplane to passing through the origin:
- In the procedure we have just described, the separating hyperplane that this algorithm will produce will be forced to pass through the origin, since the resulting hyperplane is not translated from the origin.
- We can get around that by moving our problem to a higher diminsion.
We achieve that by adding a “fictitious” diminsion as follows: - We re-write,
- \[\vec{w}\cdot X_i \rightarrow \left(\begin{array}{c} w_1 & w_2 & \cdots & w_d & \alpha \end{array} \right) \cdot \left(\begin{array}{ccccc} x_1 \\ x_2 \\ \vdots \\ x_d\\ 1 \end{array} \right)\]
- Now, we run the perceptron algorithm in (d + 1)-dimensional space.
-
- The Boundary:
- The boundary is a hyperplane:
- \[\{x \in \mathbf{R}^d : f(x) = 0\}\]
-
where \(f(x) = wX_i + \alpha\).
Convergence and Complexity
-
- The Perceptron Convergence Theorem I:
- If the data is linearly separable, the perceptron algorithm will always find a linear classifier that classifies all the data points correctly.
-
- The Perceptron Convergence Theorem II:
- If the perceptron is guranteed to converge on a data set, then it will converge in at most \(\mathcal{O}(\dfrac{R^2}{\gamma})\) iterations.
-
where \(R = \max_i \|X_i\|\), called the radius of the data, and \(\gamma =\) max margin possible.
-
- Complexity (Runtime):
- \[\mathcal{O}(n*d)\]
- Can be made faster with ‘SGD’.
- Although the step size/learning rate doesn’t appear in that big-O expression, it does have an effect on the
running time, but the effect is hard to characterize.
The algorithm gets slower if \(\epsilon\) is too small because it has to take lots of steps to get down the hill. But it also gets slower if \(\epsilon\) is too big for a different reason: it jumps right over the region with zero risk and oscillates back and forth for a long time.
Further Analysis
- Properties:
- It is an Online Algorithm.
- The algorithm is quite slow.
- There is no way to reliably choose the learning rate.
- It is currently obsolete.
- It will not converge, nor approach any approximate solutions for non-linearly separable data.


[gecode-users] Dynamically constructing a model using solution of an IntVar
Guido Tack
tack at gecode.org
Thu Aug 15 01:18:17 CEST 2013
That's more difficult. Let's say your variable that contains the required array length is called x. You either need to decompose your model into two parts (the first part determining x, the second part then using that solution to construct a new model with the right length), or you need to allocate an array with the maximum possible length and use constraints to say that everything beyond index x is ignored.
Cheers,
Guido

handler :object
A list of load handlers. These can be overriden by the user to create custom
asset load handlers. The name of the function and the name of the category within
an asset list must match.
AssetLoader provides handlers for graphics, data and text. Graphics handler is used
for loading image files. Data handler is used for loading JSON files, and Text handler
is used for loading plaintext files.
Handler functions can be overriden by the user if needed. Custom handlers can be defined
to handle custom data like audio, levels, or other custom data formats. A handler function
receives a filename and passes an object to ready().
Type:
- object
Examples
// Create a custom handler
var loader = new Z9.AssetLoader();
loader.handler.customCategory = function(filename, ready) {
// handler for customCategory
// .. do something with filename ..
var data = 'test';
// process the asset and return data with ready when done
ready(data);
};
// Override default graphics handler
loader.handler.graphics = function(filename, ready) {
// ...
};
Methods
acquire(object, keys)
Inflates an object with loaded assets.
Parameters:
| Name | Type | Description |
|---|---|---|
object |
object | Object to inflate. |
keys |
array | A list of asset keys. |
Example
var loader = new Z9.AssetLoader();
var assets = {
graphics: {
GFX_BACKGROUND: 'background.png',
GFX_SPRITE: 'sprite.png'
}
};
var graphics = {};
loader.load(assets);
loader.done = function() {
loader.acquire(graphics, {
background: 'GFX_BACKGROUND',
sprite: 'GFX_SPRITE'
});
};
state.draw = function() {
// ready to use
this.paint(graphics.background, 0, 0);
this.paint(graphics.sprite, 0, 0);
});
get(key)
Retreives a loaded asset.
Parameters:
| Name | Type | Description |
|---|---|---|
key |
string | Asset key. |
load(assetList)
Loads a list of assets. Iterates over categories in the list and then calls
the appropriate load handler on every item in the category. Note that assets
are stored in a flat array, which means that asset keys across all categories
must be unique.
Parameters:
| Name | Type | Description |
|---|---|---|
assetList |
object | A categorized list of assets. |
Example
var assetList = {
graphics: {
mysprite: 'mysprite.png',
myimage: 'myimage.jpg'
},
json: {
mydata: 'mydata.json'
}
};
var loader = new Z9.AssetLoader();
loader.done = function() {
console.log('All assets loaded and ready!');
};
loader.load(assetList);

How do I edit my FAT Table in WinHex
-
EamonStudent
I am running Winhex. I opened drive A. I am looking at the FAT Table. I went to Options, Edit Mode, In-place mode but I cannot change anything. What should I do?

Greg Hurrell
You're in the wrong place. You're looking for this company:
In the future my product ("WinHex") will be renamed so as to avoid confusion with the other product (also "WinHex") which has been around for longer.

For many immigrant families living in the US, there are language fluency gaps between parents and children. Parents who are 1st generation immigrants are often uncomfortable speaking English, the children's native tongue, while the children often lack proficiency in the native parent tongue. In any environment where it's hard to communicate, there will be tension and awkwardness, and it can be hard to know how to resolve these issues.
Found in Translation is a collaborative game that encourages conversation - both for language skill development and for encouraging regular and healthy communication at home. Our design allows families to track, review, and reward themselves for practicing conversation in any language.
Never miss a word again - Buddy will transcribe the conversation happening in real time, and the written words will appear on each user's tablet. The conversation audio is also recorded for future listening, and there's a provided section for any notes or drawings.
It's known that family games like Uno or Mario Party can often end in more disagreement than family spirit, but Found In Translation awards more score points when different people speak. Each back and forth in a conversation results in gaining more points. The game also enforces 1 speaker at a time, as only one person can hold the speaking button / ability at a time.
All past conversation history is available in the calendar. Self track your conversation habits and find out about your score history and conversation frequency and length.
Rediscover conversation audio, review and add notes, and even view your conversation translated to a different language. You can practice vocabulary, pronounciation, and grammar with real past conversations.

More holds on any more development. Again I was working on finalizing and provisioning everyone's workspaces. I first provisioned some instances to whom I thought would need the access immediately. Later in a quick meet-up with my boss's boss, I found out he wants all the same access mirrored from a list of AD groups. Well, after some investigating I will have to create 40 new accounts in AWS directory services. I have been trying to consolidate a good list as an excel document for each of the users, and their passwords. I think I will develop an AD script to bulk upload them from CSV.
I also had to work on getting the data ready for the SQL instance. I had to move a previously compressed data file for CHIA (Center for Health Information and Analysis) research. The dataset was over 700 gigabytes and I managed to compress it down to 97 gigabytes and send it off to AWS in around 12 hours using my work's internet connection. The other dataset I had to move up to AWS was a SQL database backup from 3-25. I used the same tool created by Amazon to push the data up and into Simple Storage Service (S3). The tool is written in python and called AWS CLI. Once it is set up it makes my life a hell of a lot easier.
I also got a second dataset from CHIA that is over 1.1 terabytes of data (1000 gigabytes).  I think the problem is with windows because whenever the drive is not being used, windows puts it into a standby state. The problem is that this drive immediately locks when disconnected and this standby state is triggering that. I have had the drive kill my copy commands at different intervals of time making this a harder endeavor than I initially anticipated. Anyways I have until next Thursday to get this copied and verified so I am not too worried.
This week we focused heavily on deploying everyone's code to GitHub. For the database group, we didn't have much to contribute. I decided to use my time and push database documentation and queries for the other teams to reference and use. First I started by taking Tim's ERD and lab8 to build out SQL files that could be used for both MySQL if our team used a standard LAMP/MAMP/WAMP server to host their PHP files and I also wrote the same statements with compatibility with SQLite3 for easier development since you don't have to go through the hassle of creating database credentials. The SQL statements even included some dummy data for the teams to use so their code wasn't just pointing to an empty database. For even more easier access to a working database, I pushed a SQLite db to the database folder that had the same schema and dummy data as the SQL statements.
I also created a MarkDown file that documents our team, how the columns are set up, and the ERD and Input/Output diagram for easier reference. Other than that I create a new branch called documentation which I used to put all the documents we have submitted to BlackBoard in one place as PDF files. Finally, Tim was a bit flustered with all the placeholders and documentation that was pushed to the repo, so I decided to make a production branch that would clean up the excess code and give Tim a compact version of our App so he could upload it to the server. Overall, I had a busy week.
I had a pretty cool interview with the guys at Moviri. Since the HR person was traveling for work, I got to be interviewed with some of the guys who I would most likely be working with directly. I worked on a problem to code a CLI tool to take in some comma separated files as inputs and do some bandwidth calculations to get some sort of output. I did the code in Golang, and I am pretty sure I fudged up something syntactically. I don't think I was being judged for syntax. I tried to be as clear as possible in my answers, but as the hour went on I was feeling really tired. I sort of got choked up on the open-end networking question. I wasn't particularly sure how they wanted the question answered and was confused when the technician mentioned calculations. All they wanted was my method of troubleshooting an unknown problem by looking at a graph of points for what looked like a web app which had a 20% cap for CPU utilization at no matter how many hundreds of thousands of transactions called against the application. It took a bit of time to probe exactly what they wanted, but I answered with starting to investigate the networking first if networking isn't a problem may be the application had a bottleneck in either secondary memory (RAM) or tertiary memory (HDD, SAN, NAS...). My final answer was to attack the problem first through the network, then investigate the memory storage schemes used, then finally if nothing was discovered, pick apart the application. Hope they liked my answers and want a follow-up interview.
