I studied biochemistry and engineering management in college and worked as an operations manager for 5 years before teaching myself to code. My goal is to be able to deliver complete web applications on Linux systems, so my interests lie in everything from devops automation to application code and producing a functional UI, although I’m definitely not a designer.
My biggest motivator is to always be becoming something new, better, or at the very least, different, in the hope of always challenging myself to see things in new ways. I'm at my best when I know what needs to be done and I know that the only thing in between me and a big goal is a lot of work, but I learn the most about myself when I have no idea what needs to be done and I know that only thing in between me and figuring that out is a period of focused quiet. Balancing those periods of intense action and equally intense quiet in a business environment is my greatest (business) strength, and building that discipline within a team is my value.
If you're looking for a more traditional, keyword-loaded resume, then head on over to my LinkedIn page. But if you're tired of reading bulletpoint after bulletpoint of business-speak and personal-brand-building, then read on. My goal here is to communicate what each of my experiences actually means to me and what I hope they mean to those who work with me. Hopefully it's a good read and worth your time!
My current role is heavy in Docker, Mongo and Ruby. Previous professional experience was heavy in Meteor, CoffeeScript, Bootstrap and Less. During my self-learning period, I primarily used Python and Django to learn web development. Personal projects have dabbled in ES6 JavaScript, Express and React.
One of my favorite parts of this career is that there is always plenty to learn. Beyond continuing to develop the skills and capabilities mentioned above, here are a few technologies I'd like to work with in the future, and a few things I'd like to do with them:
Go is the number one new technology that I'd like to learn in the next year or two. I've always worked in interpreted, dynamically typed languages, but I've played around with just enough Go and I've been in contact with just enough Java to have an idea of how a statically typed language could both improve my programs and challenge me to think about problems in a new way. I'm always on the lookout for small Go tools that I could build and distribute in my current devops role, and it would be interesting to see how TypeScript changes the approach to front end development after having worked with JavaScript in my first job.
My first professional role was as a full stack developer, and in that time I did my fair share of HTML and CSS work. But I know that HTML5 and CSS3 have introduced some really cool features that I'm not familiar with, and it would be interesting to learn more about what can be done in a modern browser. Having done just enough at-home React learning to know that I think it's an awesome idea, I'd also love the opportunity to see what front end programming is like in a professional, full-scale React applicatoin.
Finally, I got my web development start shipping micro-scale Heroku apps. While my current role involves a lot of devops heavy lifting on internal servers and platforms, my small business mind can't stop wondering just how much I could get done on a platform like Heroku now that I know a lot more about what I'm doing. Heroku's integration with Travis would make for an interesting project to see how far a one man show can take things on today's web.
Outside of work I'm an avid runner and reader, and occasional pianist. I spent about four years training for long course triathlons and loved every minute, but after making it all the way to the Ironman finish line in 2016 I've been spending far more time reading books learning about how people see the world in different ways. I'm loving my new, slightly more relaxed lifestlye, and am feeding the competitive spirit with some new goals of running fast instead of far.
My role at Cisco began as a contributor on a devops team supporting an already-large and growing web application, as well as supporting a number of teams contributing tools to that larger application. In my early months I learned about Docker and Rancher, Python packaging, Jenkins automation, and how to think about moving to a microservices architecture.
The first evolution of my role at Cisco came when I was given the opportunity to be the primary devops contributor on a new internal service that would be delivered as a web application. My original task was to build out the operations for the project—configuring everything from git workflows through testing checkpoints on Jenkins to automated deployment of Docker containers on a Rancher server—but when our only developer moved on to a new position I was able to step in and apply my previous development experience to fill the void and keep the project moving forward.
Working at Cisco has helped me learn more about what I really want to do, as there is simply too much going on for one person to worry about everything. That also means that there is plenty of work to go around, so you have the opportunity to decide what your role is going to be, and then make it so. From a technical perspective, I've focused on learning how to deliver web apps using Docker. But I've also tried to focus on learning from smart people who like to think about problems new ways, and who also understand the need to ensure tangible progress is being made. I've tried to communicate the ideas I was taught at Practichem—that simple, repeatable team processes enable rapid and reliable delivery, that good code style and conventions and maintainability matter as much as algorithms, and that the best way to solve any engineering problem is to sit down with a clear mind and simply start solving it.
My first professional technical position was as a full stack JavaScript developer at a biotech startup. Practichem's product was a protein chromatography instrument that ran on web software, so it was a unique opportunity to combine my biochemistry degree with my small business operations experience and my newly developed technical skills. Unfortunately, Practichem was forced to shut down a few months after I started.
I was lucky to work for an exceptional technical director at Practichem, and in only a few months of working on three Meteor applications I not only learned a ton about how to write good software, but I also learned that while I made the right decision in my career change, my five years of small business operations experience are still extremely valuable. I learned that while technical expertise is obviously important in software development, things like team processes and communication can have an outsized influence on the effectiveness of a software development team.
I had been exploring career changes for about 2 years before I left Wasatch, so this move was well-considered in some ways and spontaneous in others. I just got to a point where I knew I wanted to work in a more technical role, and a small company like Wasatch simply did not provide the opportunties that I needed. I tried to make a smooth, gap-less transition, but sometimes you reach a point where you just have to take a leap of faith and that's what I did.
My plan was to move closer to family in Greenville, SC and try to find an operations position in either the BMW or GE economies in the area, thus transitioning to a more promising operations career than Wasatch could provide. But for my first month off, I made a deal with myself that I could do whatever I wanted as long as I was working on something. I wound up spending every day studying web development, and I loved it.
I never found a job in the BMW/GE economies, but by July I had made so much progress in my web development learning that I began to think a new programming career was not only realistic but actually a better place to focus my energy. So I went all in, and began to only apply for junior web development positions. In August I found Practichem, and my bet paid off.
Between making an all-in bet on my professional career and training for my first Ironman, this period was one of if not the most rewarding of my life. I learned to trust my instincts and my unique abilities and to respect my desire for a more fulfilling life. I learned what I'm capable of doing when I commit to something, and refuse to be distracted or stop until I get where I'm going. And I learned that big, unimaginable goals like new careers and Ironman finish lines are often much closer than they appear, and all you have to do is make a little progress one day at a time, and eventually you'll find yourself in a better place.
As I continued to build my role as the operations manager, I lead division-wide operational improvements in internal communication, project management, manufacturing processes, documentation and record keeping systems, and purchasing activities. I did this by developing a system that was optimized for primarily project-based work, minimizing the need for central control to maximize flexibility and responsiveness.
The most important thing I learned in this role was how to work with different personalities and how to lead them into a common vision. You can't just tell people what to do, and different people respond to different leadership approaches. To move a team in a common direction, you have to get to know people and respect them for who they are.
This was my first job out of college where I was primarily responsbile for managing our component and finished goods inventory and maintaining the associated accounting systems. In the process I built relationships with some key suppliers, and lay the foundations of my becoming an effective Director of Operations.
But the project that stands out from all of the others is the time we didn't have enough money in the budget for a team of lawyers, so I spent a month or two teaching myself the ins and outs of ITAR law (the export laws that got Reagan in trouble) and managed to get a favorable classification from the State Department, with my arguments approved by the lawyers I was given $1,000 to work with.
I mention this internship because in many ways it set the tone for my entire career to date. The role was completely open-ended in that I was tasked with finding a way to make the lab better with zero direction as to how I should do that. I wound up teaching myself how to write Excel VBA scripts, and used that to implement an automated data analysis program for one of the lab technicians. It was the first time I combined something I knew (biochemistry) with something I taught myself (VBA), to do something nobody told me to do.
The most important course I took at Duke was Management of High-Tech Industries in which we constantly talked about the differences between management and leadership. I actually made a B in that class because I was never much for volunteering my thoughts to a class of 60, but the lessons learned have served me well.
Beyond that course, Duke was my first experience in seeing the world in a very different way, as the whole experience of graduate school in a non-technical program among a new student body stood in stark contrast to my time at Tech.
The most important thing I learned at Georgia Tech was how quickly a person can become something completely new if they have the resources to do it and they put the work in. In four short years I learned more about biochemistry—everything from quantitative methods to enzyme mechanisms to DNA transcription and translation to cell signaling pathways and systemic responses—than I ever would have though possible going in. I don't use any of that anymore (although I do secretly hope to end up in another biotech company someday), but it constantly reminds me that with the right resources and a lot of hard work, a person can become something completely new in a few short years.

South of France
The South of France blows me away every time. My family and I have been going to Beaulieu-sur-Mer for the last five to seven years. It is the perfect combination of the Mediterranean sea plus beautiful tall mountains, the view NEVER dissapoints. We enjoy staying there for months at a times, enjoying the town of Nice, the country of Monaco, and being able to reach Saint Tropez by boat is a dream come true. The South of France has a very special place in my heart and I will forever cherish its physical beauty as well as the memories I have..


--- layout: default title: "About" ---
The only reason I made this was to show you how amazing you are to me, Ellie. I really do love you with all of my heart and soul. I spent a lot of time and energy on this site. A ton of headaches and I sorta even threw my keyboard at one point. It is okay though; I needed a new keyboard anyways plus you make me extremely happy.


Developer tools allow on web pages allow you to see the elements in rectangles. You can also read the same text that is on the page Page structure is like tree branches each has an opening tag and closing tag HTML and CSS are both "languages" HTML controls the "structure" of a web page CSS controls the "style" of a page (how it looks). When programmers talk about the "DOM" (Document Object Model) they are talking about the tree-like structure of a page. All the elements on a webpage are contained in a box with its own style.
CSS stands for Cascading Style Sheets. The "C" is by far the most important part of this phrase. "Cascading" means that rules are applied not only to the elements they directly match, but also to all of those elements' child elements. However, if a child element has multiple, overlapping rules defined for it, the more specific rule takes effect.
HTML elements are boxes and each box has 4 components. Because there are so many components to each box, it can often be hard to get the size of a box just right. There are two techniques you can use to help deal with sizing issues. Set sizes in terms of percentages rather than pixels. Set the box-sizing attribute to border-box for every element. Different browsers work slightly differently. Sometimes this causes different browsers to display the same code differently.
Box Positioning Divs are block elements (as opposed to inline), so by default they take up the entire width of a page. Adding the rule display: flex; to the appropriate CSS will override this behavior and let divs appear next to each other.
Repetition of code while programming will have you doing double the work and increasing the risk of errors. Assigning a specific class Div when creating certain elements within your HTML code will help you adjust a attribute that is assign to that div. Every element that is associated with that div will be affected in the same way making the creation process more streamlined and efficient.


Deep Impact Rated PG-13 By James Sanford The Kalamazoo Gazette
Heavens above, it turns out we poor earthlings are about to be squished by a comet the size of New York!
Does President Beck (Morgan Freeman) have a plan?
Will anyone survive?
And, most importantly, will struggling reporter Jenny Lerner (Tea Leoni) get to be the MSNBC anchor person during "Armageddon"?
These and many other burning questions arise during the course of "Deep Impact," an end-of-the-world scenario that is alternately silly, sensational and soapy. But itıs rarely moving, although the screenplay by Michael Tolkin and Bruce Joel Rubin does everything but dice onions in an attempt to jerk tears. Somehow though, when the curtain is coming down on life as we know it, it's hard to fret about whether or not Jenny will make peace with her frosty father (Maximillian Schell) or what will become of teen star-gazer Leo Beiderman (Elijah Wood) and his girlfriend Sarah (Leelee Sobieski).
Not helping matters is the fact that Leo comes off as irritatingly earnest, partially due to the script requirements, mostly because of Wood's one-note performance.
Leoni's intrepid newscaster looks practically paralyzed once she gets on the air, reading bulletins in a thin, wavering voice that would inspire millions to reach for their remotes.
Obviously inspired by the 1951 sci-fi classic "When Worlds Collide" - with elements of "On The Beach" thrown in - "Deep" takes a thought-provoking premise and submerges it in suds.
While President Beck sputters sanctimony ("You will still pay your bills," he warns), a crew of astronauts led by veteran rocket-jockey Spurgeon Tanner (Robert Duvall) takes off on a mission to blow up the threatening comet. Everyone involved in this endeavor has their own family troubles to contend with, and, added to Jenny and Leoıs woes, these subplots send the film's syrup content to toxic levels.
Disaster movies by nature are overwrought, but they shouldnıt be as consistently absurd as this. For example, Sarah's doomed mom hands off her newborn to Sarah, who hops on a motorcycle with the infant, leaving without a single diaper or bottle of formula.
Somehow, no one in the Capitol seems to know about the billions of dollars being secretly diverted into the construction of the worldıs largest spaceship. And though everyone seems to know weeks beforehand that the comet's impact will create a tidal wave that will drown the East Coast, it appears there's no evacuation plan proposed.
Director Mimi Leder seems clueless when it comes to staging sentimental scenes but she does have the proper touch for the movie's few suspenseful patches, such as the truly scary sequences with Ron Eldard and company racing against time to plant nuclear "moles" on the comet's surface. The scenes of cataclysmic catastrophe in the last 10 minutes also are impressive and sometimes even imaginative: The image of the head of the Statue of Liberty floating through the flooded streets of Manhattan is particularly eerie.
If only the filmmakers had stripped away the saccharine and the self-importance of "Deep Impact" they might have found the kind of haunting epic they're trying so hard to create. Instead they've cooked up a crockful of hard-to-swallow melodrama, full of urgent weddings and quickie family reunions. It would have been much more fun to drop in on the folks who elected to party like it's never gonna be 1999.

that could be replaced with Java 8 methods:
getOrDefault()
, computeIfAbsent()
, putIfAbsent()
, merge()
, or replaceAll()
.
Examples:
String val = map.containsKey(key) ? map.get(key) : "none";
List<String> list = map.get(key); if (list == null) { list = new ArrayList<>(); map.put(key, list); }
String val = map.get(key); if (val == null) map.put(key, newVal);
Integer val = map.get(key); if (val == null) map.put(key, 1); else map.put(key, val + 1);
for (Map.Entry<String, String> entry : map.entrySet()) { map.put(entry.getKey(), transform(entry.getValue())); }
Note that the replacement with computeIfAbsent()
or merge()
might work incorrectly for some Map
implementations if the code extracted to the lambda expression modifies the same Map
. By default,
the warning doesn’t appear if this code might have side effects. If necessary, enable the last checkbox to always show the warning.
Also, due to different handling of the null
value in old methods like put()
and newer methods like
computeIfAbsent()
or merge()
, semantics might change if storing the null
value into given
Map
is important. The inspection won't suggest the replacement when the value is statically known to be nullable,
but for values with unknown nullability the replacement is still suggested. In these cases, we recommended suppressing the warning
and adding an explanatory comment.
This inspection works only if the language level of the project or module is 8 or higher

Differential geometry of curve segments | |
These methods calculate geometric quantities from given parametric ones, in an arbitrary parameter u, such that points on the curve segment are given by P(u), with 0<=u<=1. We consider the direction of increasing arc length to be the same as the direction of u. These are utility methods that can be used with any parametric curve. The idea is that you use the curve evaluators to determine the arguments here, using the same u value for each of them. If you don't use the same u value you'll get meaningless results. The primary reference for this material is the book "Lectures on Classical Differential Geometry, 2nd ed." (chapter 1) by Dirk Struik, 1961, republished by Dover in 1988. Notation and equation numbers are from that reference. Two exceptions: (1) we use c for the curvature vector rather than Struik's bold k, so we can use k for the scalar value of curvature, and (2) we define the curve normal n to point away (outward) from the center of curvature, while Struik defined it to point inward. Using our definition, if you have a parametric circle the normal points towards the outside, which is more conventional and analogous to surface normals. Our right-handed curve frame is thus x,y,z=n,t,b rather than Struik's "moving trihedron" frame t,n,b. For us the binormal b=n X t, while with Struik's definition it is t X n. Note that only the normal is reversed from Struik's, the tangent and binormal vectors are the same. | |

The Geo class collects geometric primitives intended to deal with raw, fixed-size geometric shapes occupying minimal memory and providing maximum performance through small inline methods and larger high performance algorithms.
Subclasses collect algorithms relevant to particular shapes. There are no virtual methods or class hierarchies here; each subclass is a "POD" (plain old data) class. The general idea is to make it so that these common methods are implemented in only one place in Simbody.
The Geo class itself is dataless and provides only static methods. It is also used as a namespace for geometric primitives to allow these names to be used elsewhere for more significant objects.

Given the parametric derivative Pu(u)=dP/du, determine whether the point P(u) is at a cusp, that is, a place where the arc length s does not change when parameter u does, so ds/du=0 (within tolerance).
Note that an inflection point, where the curvature is zero, is not a cusp; see isInflectionPoint(). Cost is 6 flops.
|
inlinestatic |
Given the parametric derivatives Pu(u)=dP/du, and Puu(u)=d2P/du2 determine whether point P(u) is at an inflection point on the curve, that is, a flat place where there is no curvature (within tolerance).
We will also return true if this point is a cusp, where curvature is not defined. Cost is 15 flops.
If Puu is zero or parallel to Pu (meaning it changes the parametric tangent's length but not its direction) then we are at an inflection point. We consider a cusp to be an inflection point even though curvature is undefined there, so we define an inflection point to be any place where |Pu X Puu|==0 to within tolerance.
|
inlinestatic |
Calculate the unit tangent vector t=dP/ds, given Pu=dP/du.
This is undefined at a cusp (Pu==0). See Struik, eq. 2-2. Cost is about 40 flops.
|
inlinestatic |
Return the curvature vector c=dt/ds=d2P/ds2, given Pu=dP/du and Puu=d2P/du2.
This vector points towards the center of curvature, with length equal to the magnitude of the curvature (it's not a unit vector). Curvature is undefined at a cusp (where Pu==0). Since we define the curve unit normal n to point away from the center of curvature (see above), we have c=-k*n where k is the (scalar) curvature. Cost is about 30 flops.
See Struik, eqn. 4-3, 4-4. Let prime denote differentiation with respect to arclength:
u' = du/ds = 1/|Pu| u'' = -(~Pu Puu)/Pu^4 = -(~Pu Puu) * u'^4 t = P' = Pu u' = Pu/|Pu| c = t' = P'' = Puu u'^2 + Pu u'' = Puu/Pu^2 - Pu (~Pu Puu)/Pu^4 = -k * n, k is signed curvature, n is unit normal
Note that c can be used to determine the magnitude |k|, but you can't get the sign until the normal n has been defined. We're going to define n from c, so that n=-c/|c| so dot(c,n) is always negative meaning that k is always positive for us.
|
inlinestatic |
In our definition, the unit normal vector n points in the "outward" direction, that is, it points away from the center of curvature (opposite the curvature vector c so n=-c/|c|).
This convention is the opposite of Struik's, where he has the normal point in the same direction as the curvature vector. The normal is undefined at a cusp (Pu(u)==0), and is an arbitrary perpendicular to the tangent at an inflection point (a flat place where there is no curvature, i.e. |Pu(u) X Puu(u)|==0). If the curve is a straight line then every point is an inflection point, so the normal is arbitrary everywhere. Cost is about 80 flops.
|
inlinestatic |
Return the the curvature k (always positive), and a frame whose origin is a point along the curve, x axis is the outward unit normal n, y is the unit tangent t, and z=x X y is the binormal b, which is a normal to the osculating plane.
So the vectors n,t,b form a right-handed set; this convention is different from Struik's since he has n pointing the opposite direction. This frame is undefined at a cusp (Pu==0), and the normal is arbitrary at an inflection point (|Pu(u) X Puu(u)|==0) or if the curve is a line. Cost is about 115 flops.
|
inlinestatic |
Return k^2, the square of the scalar curvature k, given Pu=dP/du and Puu=d2P/du2.
Using our definition for the curve normal n (see above), k is always positive so the curvature is the positive square root of the value returned here. Curvature is undefined at a cusp (where Pu==0) and is zero at an inflection point (|Pu X Puu|==0). Cost is about 30 flops.
|Pu X Puu|^2 k^2 = |c|^2 = ------------ |Pu|^6
See Struik, pg. 17, eq. 5-5a.
|
inlinestatic |
Return tau, the torsion or "second curvature" given Pu=dP/du, Puu=d2P/du2, Puuu=d3P/du3.
Torsion is a signed quantity related to the rate of change of the osculating plane binormal b, with db/ds=tau*n where n is the "outward" unit normal (see above). Torsion is undefined at either a cusp (where Pu==0) or an inflection point (where |Pu X Puu|==0). Cost is about 30 flops.
~(Pu X Puu) * Puuu tau = ------------------ |Pu X Puu|^2
See Struik, pg. 17, eq. 5-5b and discussion on page 16.
|
inlinestatic |
Find the points of closest approach on two lines L0 and L1, each represented by an origin point and a direction.
Points and vectors must be in a common frame. We return point x0 on L0 and x1 on L1 such that the distance |x1-x0| is the smallest for any points on the two lines. If the lines are parallel or nearly so (all points same distance) we'll pick the point on each line closest to midway between the origins as the closest points and return an indication that the returned points weren't unique.
| [in] | p0 | The origin point of line L0, that is, any point through which line L0 passes. |
| [in] | d0 | A unit vector giving the direction of L0. |
| [in] | p1 | The origin point of line L1. |
| [in] | d1 | A unit vector giving the direction of L1. |
| [out] | x0 | The point of L0 that is closest to L1. |
| [out] | x1 | The point of L1 that is closest to L0. |
| [out] | linesAreParallel | True if the lines were treated as effectively parallel. |
Cost is about 65 flops.
|
inlinestatic |
Return the default tolerance to use for degeneracy tests and other tests for "too small" or "near enough" that arise in dealing with geometry primitives.
The value depends on the precision being used; we use the SimTK constant SignificantReal which is eps^(7/8) where eps is the resolution of the template argument RealP (which must be float
or double
) That makes this tolerance around 2e-14 in double precision and 9e-7 in float.
|
inlinestatic |
Returns the square of the default tolerance.
|
inlinestatic |
Return machine precision for floating point calculations at precision RealP.
|
inlinestatic |
Return a NaN (not a number) at precision RealP.
|
inlinestatic |
Return Infinity at precision RealP. You can negate this for -Infinity.
|
inlinestatic |
Stretch a dimension by a given tolerance amount.
The result is the given length increased by at least an absolute amount tol, or by a relative amount length*tol if length > 1. Don't call this with tol less than machine precision or an exception will be thrown. Cost is 3 flops.
|
inlinestatic |
Stretch a dimension using the default tolerance for this precision as the tolerance in stretchBy().
Cost is 3 flops.

Let me start off by saying that I am an A student in all honors and Advanced Placement classes, and have only recently tried several drugs to experiement with my body and mind to see its effects, and unlock an 'in-touchness' with my mind. I have explored lucid dreaming, and decided that trying a psychoactive that makes you hallucinate would be the next best thing to dreaming lucidly, so after much research, I decided that Ambien would be a safe first try, being that before this I had only experimented with marijuana, speed, xanax, and alot of alcohol.
I used various websites to determine Ambien's safety, and decided that taking up to 20mg would not put me at too much of a risk, so long as I stayed immobile, and in my room. So after gathering information, and deciding that it would be worth a try, I attained two 10mg pills from a relative and awaited the right time and place to come for me to try it in a safe manner without attracting much attention.
So I decided to first take 10mg, thinking that it would make me hallucinate, and after some time passed I realized that it was not enough. I had hoped that only one pill would work (10 mg) so that I would have been able to experience the psychoactive effects of Ambien on two separate occasions.
7:53pm- Took 10mg of Ambien, heart racing due to nervousness.
8:05pm- ummm really tired feeling, I could pass out at any moment if I were to close my eyes.
8:30pm- I went to go to the bathroom, and upon getting up I felt a little wobbly and walking straight lines was a task.
8:35pm- I feel as if Iím stoned, or just buzzed off a few beers. Slightly eurphoric. Need some music.
8:49pm- I just took 10mg more of Ambien, because effects as I imagined had not come to be.
8:55pm- Feels good, slight visual distortions, only if I stare. Its a crazy feeling like total euphoria, like nothings real its all dream-like.
9:02pm- Feels like body is drawn into the circle hallucination.
9:05pm- Feels like I am being drawn towards the computer. Another hallucination.
I felt as if I had melted into the computer screen, and I was one with the screen. I had to remind myself every so often that I was on Ambien, and that it wasn't real what I was seeing or feeling. I got very confused by the computer and the IM boxes from AOL, which made no sense to me, and they were all highly zoomed and distorted. I tried talking to friends online, but since my motor skills were totally messed up, by the peak of the sedative effects of the Ambien, I was unable to type correctly and in a coherent manner.
I got frustrated by the confusing boxes appearing on the computer, and my 'melted-ness' into the screen, so then I shut off the computer screen and lied down on my bed--BAD MISTAKE, I last remember watching TV (no recollection of what was on TV), and then after that I'm guessing I blanked out and fell asleep, but at no time did I consciously make the decision to sleep, or close my eyes. I awoke the next morning to my mom saying my name and telling me to wake up, ever-so-energetic and awake, feeling 100% rested, and not the least bit groggy.
Ambien was a generally positive experience. I learned from my experience that 10mg is not enough to hallucinate, it only makes me feel drunk/stoned with a mix of euphoria, but with 20mg, I hallucinated, and felt completely euphoric and generally unaware of my surroundings. I would definitely try this great drug again, and do it in an environment that is somewhat stimulating, and will not let me fall asleep, Definitely with other people (friends) around to amuse me to help keep me awake to enjoy the effects.

The radio presenters wisely left their partners at home to tuck in the kids as they attended Global’s Make Some Noise event in London on Monday night.
Myleene, who gave birth to her first son Apollo this summer, shimmered into the venue in a black and gold strapless gown, while Amanda kept it clean in a white asymmetrical jumpsuit.
The pair had each other for company as they walked the red carpet and seemed to share each other’s joy as they smiled and laughed with each other.
And the fun didn’t stop on the red carpet as Myleene, 41, shared a video of her bubbling champagne glass while singing her heart out to Paul Walker who was performing along with Stephen Miron.
Advertisement Advertisement
Global’s Make Some Noise is a national charity which funds and empowers smaller charities across the UK, helping disadvantaged children and young people.
Elsewhere on the red carpet, Amanda also stopped to take photos with her Heart Breakfast co-host Jamie Theakston and with them both out on a Monday night, we won’t envy their heads tomorrow morning.
Other stars in attendance were Marvin Humes, Kelly Brook, Kirsty Gallacher and Georgia Toffolo, while singer Freya Ridings also did the honours of performing.
Smooth radio host Myleene spent some quality time with her baby boy hours before hitting the red carpet, and shared a cute video of the three-month-old snoring while having a good nap.
Apollo was probably tired out after being serenaded by his older sister, Myleene’s 12-year-old daughter Ava, who played the piano as he wriggled away in his baby chair.
‘He gets a private concert every morning! Some blues for Apollo this morning,’ Myleene captioned the adorable Instagram story.
Detailing Apollo’s ‘complicated’ birth back in August, Myleene recently revealed how she ‘lost five hours of her life’.

‘He gets a private concert every morning! Some blues for Apollo this morning,’ Myleene captioned the adorable Instagram story.
Apollo is the god of music and science – my two passions. We thought it was such a strong name and at 8lbs 5oz, he was a strong, bouncing boy,’ she told Hello magazine.
‘My waters broke and I was in the birthing pool. We had a really easy first three hours, to the point that I thought we would all be home by 7pm. But I don’t remember what happened next. I lost five hours of my life and it was a pretty complicated birth in the end.’

Brief Introduction
Today, such advertisements, which include videos, interactive infographics, and articles, are quickly gaining traction among both brands and publishers. In fact, you’ve probably scrolled through thousands of them on CNN, BuzzFeed, USA Today, etc., without consciously recognizing branded content.
Ad Blockers
Ad blockers have become more popular than Donald Trump, and because both advertisers and publishers are suffering from ad blocking, branded content and native advertisements are being championed as a solution to the overwhelming revenue losses. It’s proving to be a great alternative to traditional banner ads, which users are resisting.
General overview
In the last article, I focused on advertisements in general. However, this time I’d like to introduce a new theme: branded content, or content that subtly blends into editorial publications and other media communications.
Ad blockers have become more popular than Donald Trump, and because both advertisers and publishers are suffering from ad blocking, branded content and native advertisements are being championed as a solution to the overwhelming revenue losses. It’s proving to be a great alternative to traditional banner ads, which users are resisting.

My wireframe was very simple, so translating it into HTML was not super difficult. Some of the HTML5 tags were new to me: section, aside, nav, and article. I think they're a really great idea, though, because the div tag was way overworked. HTML5, in general, seems like a very good upgrade to HTML4.
I am very excited to start incorporating my design next week. My website relies heavily on colors and fonts, so I think it will be a big improvement.

Build your own React
We are going to rewrite React from scratch. Step by step. Following the architecture from the real React code but without all the optimizations and non-essential features. If you’ve read any of my previous “build your own React” posts, the difference is that this post is based on React 16. pomb.us Rodrigo Pombo

I remember my own struggle with calculus at university. Limits, integrals, differential equations. Lots of practice, lots of homework. Pages and pages of exercises. I loved math, the connection between algebra and geometry, the very pleasure of solving problems by making different concepts work together. But I hated doing the “paperwork”.
Taking it seriously, I still studied through the semester, studied harder the week before the exam, studied even harder the night before. I got 62/100. That's 1 point above the lowest possible passing grade.
Well, maybe math is not for everyone. But wait a minute! The next semester I took part in the Math Olympiad, went through the faculty round, then through the university round, went to the nationals, and even managed to score a few points there. Which counted as a pass on that semester's exam.
Professors were proud of me. And for almost a year, they thought that the first semester's score was a mistake. Until in the third semester, I scored 65/100.
¯\_(ツ)_/¯
Mathematics is a lot of things. It's the fun of problem-solving, it's the excitement of discoveries, it's the pride of accomplishments, and it's a ton of tedious computations, too. I never liked that last part. I still don't. That's why I'm so happy to live in the XXI century since I can give it away to computers and still enjoy the first three.
According to the official site:
SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible.
Symbolic mathematics? Algebra system? Sounds exclusive. Sounds like it's a tool for practicing mathematicians and the students who desperately want to become one. But it isn't. It's for practicing engineers who have just enough math knowledge to state a problem but not enough patience to solve it.
It does integration and differentiation. It finds limits, and it expands series. It solves equations and systems of equations. It can even do statistics. And it does it all just like you would do on an exam. It doesn't just compute numbers, it computes formulas.
It's a Python library that does the boring part of math for you. Moreover, it does it fast, accurately, and without angst. In other words, it is everything I'm not.
Let's say we want to model the sine function with a polynomial. Let's pretend we have a reason. Now how do we do that?
How about, we gather all we know about the sine function in one bowl and let SymPy do the rest? Sounds good?
sin(x)
We know that sin(0) = 0, right? Everybody knows that. Also, as you might have heard, you can approximate a small sine with its own argument: sin(0.001) ≃ 0.001. This means that the derivative of sine in 0 is 1.
The sine function climbs from 0 to π/2 and then it starts going down. In π/2 it's neither climbing nor descending, it's at its peak. This means that the derivative of sin(π/2)' = 0. Also, since the sine only climbs to 1, sin(π/2) = 1.
The sine is symmetrical relative to π/2. This means that it descends exactly as it climbs, and at the point where it reaches full π, its derivative is sin(π)' = -1, and the function itself sin(π) = 0.
Also, one less known (but easily computable) fact, the integral of the sine from 0 to π/2 is 1. Let's throw this into the bowl as well.
So, we have 7 facts. This implies 7 equations. This implies that our polynomial will have 7 coefficients and the highest degree will be then 6.
Let's translate it all into Python.
from sympy import * a, b, c, d, e, f, g, x = symbols('a b c d e f g x') sine = a*x**6 + b*x**5 + c*x**4 + d*x**3 + e*x**2 + f*x + g sine_d = diff(sine, x) sine_i = integrate(sine, x) the_system = [ sine_i.subs(x, pi / 2) - sine_i.subs(x, 0) - 1, sine_d.subs(x, 0) - 1, sine_d.subs(x, pi / 2), sine_d.subs(x, pi) + 1, sine.subs(x, 0), sine.subs(x, pi / 2) - 1, sine.subs(x, pi) ] res = solve(the_system, (a, b, c, d, e, f, g)) for var, exp in res.items(): print(var, srepr(exp)) |
You can browse the tutorial if you like but it should be more or less clear as it is. sine is our polynomial model. diff is differentiation. integrate is integration. solve is solve. Simple! The only cryptic thing here is srepr. It turns the solution into a special form of expression that looks like this:
(f, 'Integer(1)')
(c, 'Mul(Integer(5), Pow(pi, Integer(-5)), Add(Mul(Integer(-1), Integer(288), pi), Mul(Integer(-1), Integer(19), Pow(pi, Integer(2))), Integer(1092)))')
(d, 'Mul(Integer(10), Pow(pi, Integer(-4)), Add(Integer(-252), Mul(Integer(5), Pow(pi, Integer(2))), Mul(Integer(64), pi)))')
(a, 'Mul(Integer(28), Pow(pi, Integer(-7)), Add(Mul(Integer(-1), Integer(16), pi), Mul(Integer(-1), Pow(pi, Integer(2))), Integer(60)))')
(e, 'Mul(Integer(12), Pow(pi, Integer(-3)), Add(Mul(Integer(-1), Integer(8), pi), Mul(Integer(-1), Pow(pi, Integer(2))), Integer(35)))')
(g, 'Integer(0)')
(b, 'Mul(Integer(84), Pow(pi, Integer(-6)), Add(Integer(-60), Pow(pi, Integer(2)), Mul(Integer(16), pi)))')
Ok, this is not really helpful. We need the coefficients and SymPy gave us the way to compute these coefficients from π. Well, it's what it does, it computes things symbolically not numerically. Or does it?
Look! I'll add one more line and SymPy will compute our coefficients as floating-point numbers.
from sympy import * from math import pi a, b, c, d, e, f, g, x = symbols('a b c d e f g x') sine = a*x**6 + b*x**5 + c*x**4 + d*x**3 + e*x**2 + f*x + g sine_d = diff(sine, x) sine_i = integrate(sine, x) the_system = [ sine_i.subs(x, pi / 2) - sine_i.subs(x, 0) - 1, sine_d.subs(x, 0) - 1, sine_d.subs(x, pi / 2), sine_d.subs(x, pi) + 1, sine.subs(x, 0), sine.subs(x, pi / 2) - 1, sine.subs(x, pi) ] res = solve(the_system, (a, b, c, d, e, f, g)) for var, exp in res.items(): print(var, srepr(exp)) |
Have you noticed which line it is? Anyway, the result is now this:
(f, "Float('1.0', precision=53)")
(c, "Float('-0.0049207268278655082', precision=53)")
(d, "Float('-0.16323406244002545', precision=53)")
(a, "Float('-0.0012523393437231091', precision=53)")
(e, "Float('-0.00090780192609864056', precision=53)")
(g, "Float('0.0', precision=53)")
(b, "Float('0.011803020246125803', precision=53)")
The line was from math import pi. This overloads the pi in the scope to be a floating-point number, not a symbol. And voilà — SymPy is now numeric. We can take these numbers, put them into our polynomial and it will be our model.
Polynomial model put over original sin(x)
The model works wonders in the [0; π] range. Outside this range it diverges from the sine but we never specified that it shouldn't.
The polynomial bears all the properties we told SymPy about with our equations and nothing more.
Let's say we want something that looks like the sine but isn't. Something we can tweak interactively. Like the sine but with the movable middle point.
We can start the same way. Let's retain the point locations. The integral criterion along with the derivatives in the endpoints are better to be lifted. But that's just my opinion, you can try to retain them yourself and see what'll happen.
The code that states the problem looks like this:
from sympy import * a, b, c, d, x, px, py = symbols('a b c d x px py') sine = a*x**3 + b*x**2 + c*x + d sine_d = diff(sine, x) the_system = [ sine_d.subs(x, px), sine.subs(x, 0), sine.subs(x, px) - py, sine.subs(x, pi) ] res = solve(the_system, (a, b, c, d)) for var, exp in res.items(): print(var, srepr(exp)) |
When run, it prints out that:
(c, "Mul(pi, Pow(Symbol('px'), Integer(-1)), Symbol('py'), Add(Mul(Integer(-1), Integer(3), Symbol('px')), Mul(Integer(2), pi)), Pow(Add(Pow(Symbol('px'), Integer(2)), Mul(Integer(-1), Integer(2), pi, Symbol('px')), Pow(pi, Integer(2))), Integer(-1)))")
(b, "Mul(Pow(Symbol('px'), Integer(-2)), Symbol('py'), Add(Mul(Integer(3), Pow(Symbol('px'), Integer(2))), Mul(Integer(-1), Pow(pi, Integer(2)))), Pow(Add(Pow(Symbol('px'), Integer(2)), Mul(Integer(-1), Integer(2), pi, Symbol('px')), Pow(pi, Integer(2))), Integer(-1)))")
(a, "Mul(Pow(Symbol('px'), Integer(-2)), Symbol('py'), Add(pi, Mul(Integer(-1), Integer(2), Symbol('px'))), Pow(Add(Pow(Symbol('px'), Integer(2)), Mul(Integer(-1), Integer(2), pi, Symbol('px')), Pow(pi, Integer(2))), Integer(-1)))")
(d, 'Integer(0)')
And now it's time to get back to that cryptic srepr thing from before. It stands for symbolic expression, and it's basically a ready-made syntax tree. It's like in Lisp only with somewhat more conventional parentheses. And since it's written in conventional C-style function form, it's incredibly easy to write an interpreter for it (see: the code on GitHub).
For instance, here is a simple tool that turns SymPy s-expressions into runable JavaScript code.
Just press the button — and that's it! Of course, you can prettify the code however you like. But you can also use in raw like this (see: the example from this very page).
You can drag the point. SymPy generated code will recompute the curve.
But the best part of it, unless you're writing in some esoteric language, you don't even need an interpreter. SymPy can print out JavaScript code from the box with a single jscode function! It can also print in Rust, C++, Fortran, Matematica, and more. It's already there.
They say that AI will replace programmers in the future. Well, for a certain part, the future is here. SymPy writes your code for you. Although, when writing code means translating equations without any creative thought involved, I don't mind being replaced.
I disagree with “math is not for everyone”. Math is vast and diverse. Surely there is enough math for everyone. But some parts of it are better left to computers.
Hope this demonstration shows that computers are happy to help you. It's not that hard to state a problem and it's even easier to interpret results. And it's fun.
If my humble introduction to SymPy will help you enjoy math long after your final calculus exam, it'll make me happy too.

CSS Technical Blog
March 3, 2015
Since week 2 had a reputation for being the most time-consuming, in true Sam-fashion I started on the challenges Friday night and worked through the weekend. I have a fear about not being able to succeed at this, compunded by working at my job full-time still, so it's important to me to be as ahead of the ball as I can be. I had started the HTML Codecademy course before Phase 0, but I had never heard of or touched CSS. For someone who doesn't know either, you can think of HTML and CSS like a recipe. The list of ingredients is the HTML code, whereas the instructions are like the CSS. The CSS tells the browser what to do with your HTML, and how certain elements should blend together.
To be honest, after going through the tutorial, I felt much better about the whole language. HTML didn't make too much sense on its own (just like a recipe is rendered useless if you only have the list of ingredients), so CSS really cleared up the whole website-building business. There are still many aspects of CSS I haven't delved into yet I'm sure, but today I'll be blogging about 2 topics I had issues with when first using it: when to use a class vs. an ID, and what the difference is between displaying an object inline vs. inline block.
One of the first technical bumps I ran into when creating my website was styling only certain portions of the HTML document. To stick with the recipe metaphor, I wanted to know how to blend the sugar with the butter, in isolation of how the rest of the recipe comes together. I knew there was a way to tag certain blocks of code as either a class or an ID, but to me they pretty much meant the same thing. After doing some research (and to be honest, playing around with my website), it looks like best practice is to use a class when multiple elements of your site need to be styled the same way, and to use an ID only on a specific one-time-use case. I also found a great section in the CSS recommendations regarding specificity: an ID is vastly more specific than a class and as such will overrule other rules. This is important when creating your CSS as it helps you figure out which portion of the CSS the HTML will follow.
Another aspect that I had to do some extra reading on was the display rule. In CSS, you can tell certain objects how to display on the page. Three of those selections are inline, block, and inline block. Displaying an object as a block renders the object literally as a block. Each object turns into a square shaped area, and each block stacks under the previous one. Displaying an object inline means pretty much what it says. You can think of inline objects like text. Each object goes to the right of the previous one, and they continue to loop around onto the next "line" of your page.
One of my initial questions was "What is the different between displaying objects inline vs. inline block?". I think a visual is the best way to understand this concept, but it looks to me like inline block is essentially the best of both an inline object and a block object. Both inline and block displays are relatively rigid: inline elements cannot have a width or a height set, and block elements force a line break after it (stacking). Inline block combines the two and allows elements to sit next to each other horizontally while also respecting a defined height and width. Here is a visual representation:


Your ultimate all-in-one guide to dying gloriously with your fellow comrades!
The Arma series aren't just amazing games, they're platforms for a huge variety of experiences: ArmA 2™ gave us realism, WWII and DayZ, to name just a few (even before you open up the editor and make your own). Now, ArmA 3™ is taking us to the future. We believe all the best experiences begin with a great community. Our regular sessions feature tactical gameplay with consistent in-game organisation, multi-layered comms and a mix of coop and adversarial missions created by members of our community. However, we're not MilSim: there are no ranks or mandatory training - just friendly people.
You won't need any mods, just the latest non-dev version of ArmA 3 (including the APEX expansion) and TeamSpeak 3. There are no applications or tests. We only ask that you read through our introductory information.
To get in touch, register on our forum or join our Discord (chat) server (no installation required). Wherever you end up playing, we hope you'll enjoy playing ArmA games as much as we do.
Visit our forum for 5+ years of 'after action reviews', watch one of our YouTube channels or play these highlights:
Transcript approved for training purposes
Uh, hello?
Welcome, comrade! The Third International Fighting Brigade of Takistan in the name of Che Guevara is overjoyed to have you with us. I can see that you are ready to charge off into action. Unfortunately, you will have to curb your enthusiasm for a bit, as our scheduled operations do not begin before 1920 UK time, every Sunday and Tuesday.
The what now?
The sessions, of course! Twice a week, we will embark on a mix of Coop and PvP missions. Generally, they are affairs of 20-50 organized, focused individuals, who can be relied on to bring them to a close within 40 min, without resorting to revive or third person.
Oh, yeah, the sessions. That's what i came here for. What are the requirements for joining up?
To attend, you will need the latest (official, stable, non beta version of) Arma 3, and (the latest stable, non beta version of) TeamSpeak 3. The Arma 3 DLC is not strictly required, but players who don't have the APEX expansion will not be able to participate in missions set on Tanoa. There are also no required addons. There is a small list of optional addons, but they are, as the name says, optional.
So that's for "attending". What if I want to join?
There is no "joining" process in FA. Everyone is welcome to hop on and play. There is also no saluting, no ranks, and the slots are handed out on a 'first come-first served' basis, and you can take any slot the host calls out, be it commander, tanker, pilot, or the common grunt.
That's cool!
Yes it is.
Wait, there are no ranks, but there's a commander?
Exactly. Anyone can step up to command, anyone can step up to be a grunt. But whatever slot you pick for the mission, stick to it. If you're a rifleman, do what your unit lead tells you. If you're a unit lead, do what your commander tells you. If you're a commander, devote your time to actually commanding. ArmA works best as a team sport. Folk ARPS believes you don't need ranks to be a team.
But what if I screw up?
 Like most other things in FA, competence is entirely optional. Your comrades will not feel less of you for trying. Or else.
Uh...
But enough about unpleasantries. Step right on to the next room, while we walk you through the standard setup:
Transcript approved for training purposes
So, first of all, before you join, you should probably set up your Teamspeak client
How do I set up Teamspeak?
For starters, if you don't already have it, download the latest version of TS3 from their website and install it. Once it's installed, launch it and connect to server.folkarps.com:9988. The password is freedom. You will be connected to "General Chat", at the very bottom of the list. For the session, move to "Limbo", at the very top of the list. Next, you should probably join the game server.
How do I join the ArmA 3 server?
In the ArmA 3 Launcher that starts when you launch the game from Steam, go to SERVERS, then INTERNET, then search for 'folk' (it may take couple of minutes). Of the two servers found, select the "Folk ARPS" server and click "join". The password is "freedom".
The server just kicked me.
Yeah, that tends to happen if you have non-authorized mods. Close the game, disable any non-authorized mods (or, as a last resort, all mods) and try again.
Ok, I'm in. What now?
Now we wait for the host to pick a mission. Once everyone is in the Limbo channel and on the game server, the Host load up a mission and begin calling slots. For example, the Host will call for a Commander, and open the CO slot. Whoever takes the slot is the commander for the duration of the mission. Next he will call the SL, then FTL etc. Once everyone is slotted, the session Host will launch the mission, ask you to move to a different Teamspeak channel, which will be used for the duration of the mission.
So how do the actual missions work?
Once the mission is launched, you will see the briefing screen, and should move any banter to the sidechat (press '/' to type, press 'enter' to send). This gives the CO time to read the briefing and think of a plan in peace. It's a good idea to read the briefing yourself. When the CO is done planning, he will then share his plan with the rest of the platoon, and the mission will start. When If you get killed, return to Limbo, and once the mission ends, the Host loads the next mission, and the slotting starts again.
Hold on. If just anyone can join, then how do you keep out the... how to put this... more disruptive people from ruining the sessions?
The Host team has methods of enforcing etiquette
The, uh, the etiquette?
Oh, that's right, how (ironically) rude of me! Step right into the next room:
EtiquetteTranscript approved for training purposes
So, what is the etiquette?
We ask that every comrade observes a few very simple principles with regard to communications, gameplay and banter:
That seems reasonable. What about during gameplay?
If you do only one thing, simply to follow the orders of your element leader and avoid lone-wolfing. Beyond that, we like to respect the design of each scenario and play the parts we have selected during slotting: unless ordered to, please don't scavenge for fancy/different weapons or vehicles not relevant to your role. Non-regulation gear tends to attract friendly fire and falling submarines.
What?!?
Nevermind. Just follow the etiquette and keep the banter to chat during planning.
Is, uh, is there an etiquette guide for banter?
Just one rule: please don't use humour that is at the expense of any group of people, be it defined by gender, race, sexual orientation, nationality, political views etc. At FA, everyone is welcome - because we all strive to ensure nobody feels unwelcome. We're sure you already know that outright sexism, racism, homophobia etc. are unacceptable here (as in many communities) - we just ask that when you crack a joke or make a witty comment, you consider first whether it will make someone feel unwelcome. If your remark boils down to 'lol, gay'/'lol, swedes'/'lol, rape', then it's just not our kind of banter. This applies not only to 'Banter' banter, but to any and all FA comms channels, be it forums, Discord, or party-approved carrier pigeons.
But what if me and my friend have this in-joke that s/he doesn't find offensive at all, even though it's about Swedes and Australians and sex? Isn't this all a bit Social Justice Warrior?
Remember that anyone can participate in our sessions - new comrades might not understand that you're friends, and may feel uncomfortable enough not to come back - which would be a shame for you, them and everyone who works hard to make the sessions happen. This isn't about politics for us, it's about ensuring that FA is a community where absolutely anyone can come and enjoy some tactical ArmA. Even sex-loving Swedes and Australians.
Ah ... yeah, that makes sense now that you put it that way. So what happens if someone says something that makes me uncomfortable?
Contact any of the hosts and they'll do all they can to resolve the situation. Hopefully without having to use a Party-issued Makarov.

Basically.
Anything else I should know?
I am glad you asked! Step right on through this bunker for the organisational briefing:
FA PlatoonTranscript approved for training purposes
So, what exactly are all these CO, SL, FTL things I keep hearing about?
The missions (mostly) incorporate the FA2015 Platoon structure. The Platoon, led by a CO, consists of three Squads, led by SLs, each made up of two Fireteams, led by FTLs.
Oh, well, obviously. But let's pretend for a moment that I didn't understand a word of that...
You'll figure it out the minute you see it in action. If you're 100% new to this, my advice would be to grab one of the 'riflemen' slots. You can even ask the host to save you one. It's a perfect position to see how the system works, and it takes no prior knowledge past "listen to your leader" and "point and shoot".
Right. But suppose I still wanna hear the details?
Allrighty then:
The fireteam element consists of the Fire Team and Maneuver Team. They all talk to eachother over Group VON (AKA the in-game channel). It's advised to have a dedicated push-to-talk key set up for group VON exclusively.
Fire and Maneuver?
Exactly. One team suppresses the enemy (so they can't shoot back), and then the other team moves in for the kill.
An infantry squad consists of two fireteams and the Squad Leader element (basically, SL and Medic). SL and FTLs talk to each other over TeamSpeak.
So, if I'm not an SL or FTL...
You generally don't talk on TS. Unless there's something really, really urgent.
An infantry platoon consists of (up to) three squads, attachments, and the CO element (basically CO, Medic, and UAV operator). The CO and SLs speak to each other over Chanel Commander.
Infantry squad. There are other kinds?
Very observant! There is, indeed, a mechanized squad. Basically, the mech. squad trades one fireteam for an armored transport/fire support vehicle.
And as you can imagine, three mech. squads and attachments make up a mech. platoon.
Wait, what are 'attachments'?
Attachments are typically 2-man elements (spotter and gunner) that can be used to add a specific type of special weapon to the platoon. For example, the Heavy AntiTank (HAT) team adds, as the name suggests, a heavy AT weapon. An MMG team adds a medium machinegun, which is bigger than what the automatic riflemen have. A mortar team, well, you get the picture.
So, where do they fit on the diagram?
Wherever the CO wants them. When attached to a squad, the Attachment lead (the 'spotter') talks on TS. When attached directly to CO, they speak on Chanel commander.
Wait, wait, back up: what's "Channel Commander"?
Oh, right, that thing. Well, CC is a TeamSpeak feature that lets you talk to people outside of your channel. We use it for comms 'one level up' from TS. You can more or less ignore it unless you slot as an element lead. or your lead gets shot and you have to take over.
And if that happens?
I am glad you asked! Proceed right down this hatch for your comms training:
TeamspeakTranscript approved for training purposes
OK, I got the latest Teamspeak 3 from the website, and have it installed and launched.
Go to "connect" and use these details:
I'm connected. Which channel should I go to?
For the session, you're going to start with "Limbo (Slotting/Dead)". When you've just arrived, hang out there. When the mission starts, everyone will move to the appropriate side channel family (BLUFOR/OPFOR/INDFOR). Further channel split will be handled by the CO. When the mission ends (either for everyone or just for you) return to limbo, and wait for the next mission.
What about Channel Commander?
CC is a TeamSpeak feature that lets you talk to people "over the fence" of your channel. The setup we use is pretty straightforward:
And you're set. To turn CC on/off, either right-click your name in the playerlist and select Channel Commander, or set-up a hotkey (or combination, such as Shift+H):
Sounds technical
Sounds, yes. But once you see it in action,it gets intuitive. In general, it's highly recommended to have CC if you plan on taking leadership slots. Or, when your superior gets shot, and you get assigned leadership.
That doesn't sound like something that should happen very often, right?
Er...Well, why don't you follow me to the leadership course, just in case?
LeadershipTranscript approved for training purposes
So, suppose I get 'promoted' to a leadership position. How do I exactly run my unit(s)?
That's a difficult one, but there are a few best practices:
Got it. I think. Wait, is there anything I shouldn't do?
Lots. Here are some to things to watch out for:
Well, thanks. That was a fairly comprehensive infodump.
The pleasure is all mine, comrade. The Party is always happy to help. if you have any other questions, feel free to ask in our Discord channel. Now please, after me:
DeploymentTranscript approved for training purposes
I really liked the presentation so far, but I don't think I'm quite ready to hop on just yet. I was thinking maybe I'll... wait, why are you handing me a bag of ammo?
You can thank me later, comrade. Your uniform is also inside.

Supply depot, naturally! Where else to we get you your equipment? Oh, and here's your helmet.
Is that a BTR?!?
Of course. And your trusty AK is waiting inside!
...You know what, maybe I 'll come round some other time...
  Now, really, and before I draw my Makarov ... Get. On. The. Troop. Transport.
Are any of the addons listed on this page required?
No. all addons listed on this page are optional. You can choose to use all, some, or none of them in an FA ArmA 3 session.
Can I use any client-side addon in an FA session?
No. We are currently white-listing addons on the ArmA 3 server. Only the addons listed and linked to in this post are permitted (the server will not let you connect with other addons).Already included in the swifty repository:
ZEUS addons - running these addons as ZEUS will guarantee players a similar experiencing as with our server-controlled AI
Not part of the swifty repository:
Optional TeamSpeak 3 addons:
Automated Folk ARPS mod repository
Folk ARPS does maintain a repository for Swifty, a highly recommended and very lightweight tool to keep mods up to date and in synchronization with our server.
So, I've got this mission idea I would like to make for us to play, but I have no idea where to begin.
Don't worry, comrade, the Party has got your back. All you have to do is follow this simple missionmaking checklist, using the convenient, streamlined, hassle free system of the FA Template!
The FA Template?
Comrade, am I glad you asked!
