Project evolved from Continuous MDP.
The optimal action (for fixed horizon \(T\), take \(T= \iy\) to get the infinite-horizon case) is given by \[ a = -P_{t}x \] where \(P_{t}\) satisfies the matrix Riccati equation. For the infinite horizon case, take \(T=\iy\) and find that \(a=-Px\) where \(P\) is the solution to an algebraic Riccati equation, which has an expression in terms of eigenvalues of \(\matt{A}{BB^T}{Q}{-A^T}\).
For example, take \(g\) to be a convex function.
Idea: Approximate \(g\) locally with a quadratic function and then make the action that optimizes the linear quadratic system.
The problem to find the function \(a(t)\) that maximizes \(V_{t}(x,a)\). Especially we care about when \(T\to \iy\). There are two ways to solve this problem:
Use Pontryagrin’s maximal principle to write this as a Hamiltonian system. One can show the optimal control has the form \(a(t) = -P(t)x(t)\). Get a differential equation in \(P(t)\) which is the matrix Riccati equation.
For infinite-horizon, the optimal control is \(a= -Px\) independent of time. (Reparameterizing \([0,\iy)\) as \((-\iy, 0]\), the solution \(P\) is the limit \(\lim_{t\to \iy}P(-t)\).Use the Bellman-Jacobi-Hamilton equation. Let \(v(x,t) = \max_{a(\cdot)} V_{t}(x,a(\cdot))\). Then \(v\) satisfies \(v_t + \max_a [r(x,a) + (\nabla_x v)^T f(x,a)]=0\). \(v(x,t)=-x^TK(t)x\) is quadratic in \(x\), \(a\) is linear in \(x\), and we also get a matrix Riccati equation in \(K\).
For infinite-horizon, reparameterizing \([0,\iy)\) as \((-\iy, 0]\), the solution \(v\) is a steady-state solution, \(\max_a [r(x,a) + (\nabla_x v)^T f(x,a)]=0\).
We want to generalize \(\rc 2 x^TQx\), e.g. to \(g(x)\). Suppose that \(g\) is convex. In general it’s infeasible to solve for the optimal action (you can only numerically approximate the solution, which is infeasible in high dimension); the question is whether we can find a simple policy \(a\) that approximates the optimal action (e.g. up to a constant factor depending on properties of \(g\)). For example \(a(x)\) could be chosen based on a quadratic approximation of \(g\). For a particular choice of \(a(x)\), the value satisfies \[ -g(x) - \rc2 a^Ta + (\nb_x v)^T f(x,a) = 0 \] and for the optimal choice \(a(x) = B^T(\nb_x v)\) the value satisfies \[ -g(x) + \rc 2 (\nb_x v^*)^T BB^T (\nb_x v^*) + (\nb_x v^*)^T Ax=0 \] We’d have to relate \(v\) and \(v^*\) in some way.
Fix \(x_1\). Letting actions be \(a_1,a_2,...\) and the recurrence be \(x_{n+1} =Ax_n+Ba_n\) we want
\[\begin{align} &\quad \min_{a_1} [g(x_1) + ||a_1||^2 + \min_{a_2} [g(Ax_1+Ba_1) + ||a_2||^2 + ...]] \\ &= \min_{a_1,...,a_T} g(x_1) + ||a_1||^2 + g(Ax_1+Ba_1) + ||a_2||^2 + g(A^2x_1 + ABa_1 + Ba_2) +... \end{align}\]and the objective is jointly convex because we are assuming g is convex, and a convex function composed with a linear function is convex.
Optimizing this function in various settings with various algorithms (like alternating minimization) sound pretty plausible given that it’s convex.
The observation above seems to suggest that for any loss function and any dynamics, if we believe that the non-convex optimization can converge to some good minimum, then this whole problem is solved. But of course, in practice, the dynamics and loss function are not known, and we can only observe the state transition and loss value for the state that we have reached.
So the situation here is a bit analogous to the situation we faced for offline optimization v.s. online learning and bandits. Our “offline” case (or full observation case) is tractable and we need to extend this to the “online” or “bandit” case where we don’t know the model (i.e. dynamics). Because the full observation case is tractable, I felt that there are ways to extend it to partial observation case using similar exploration-exploitation intuition in bandit.

Cutting edge: expression of the NF of activated T cells in eosinophils: regulation by IL-4 and IL-5.
Abstract
We report that NF-AT1 and NF-AT4 are expressed cytoplasmically in resting eosinophils, whereas NF-AT2 and NF-AT3 have not been seen. Likewise, NF-AT1 mRNA and NF-AT4 mRNA have been detected in resting eosinophils, and their levels can be significantly up-regulated by the Th2-associated cytokines IL-4 and IL-5. There is no detectable NF-AT protein expression in the nuclei of resting eosinophils. However NF-ATs appear in the nuclei of IL-4-, IL-5-, or ionomycin-stimulated eosinophils. Only NF-AT1 and NF-AT4, but not NF-AT2 and NF-AT3, have translocated into the nuclei in IL-4- or IL-5-stimulated eosinophils. These findings delineate a novel pathway in the cytokine network in which Th2 lymphocytes `` control '' eosinophils via the release of IL-4 and IL-5, and activation of NF-AT in eosinophils. The findings also suggest that a later feedback `` talking '' may exist between eosinophils and Th2 lymphocytes.

Maintaining a network of air quality sensors across the Heathrow area, Breathe Heathrow is a project managed by OpenSensors.io, funded by the Open Data Institute as part of it's Summer Showcase. The project seeks to experiment with and understand new data-driven methodology for air quality measurement.
The graphs and mapping on this site are a representation of the air quality data measured by the sensor network. All of our sensors publish Open Data to the OpenSensors.io platform, where it is freely accessible, shareable and usable by all through an Open Data licence.
The Breathe Heathrow project uses Air Quality Egg V2 air quality sensors, modified to include noise measurement. You can find out more about the Air Quality Egg project and community at airqualityegg.com.
The map shows the live state of sensors in the residential areas surrounding Heathrow Airport and a visualisation of the air quality levels in the area.
To derive this map from the air quality sensor data, we use a process called interpolation. This is a method for finding the value of intermediate values having a discrete set of known values in computational mathematics. The result is a graphical representation consisting of isolines and isobands based on the sensor data.
This graph represents the air quality measured by the sensors for each hour over two days. The graph includes data from all the sensors contributing to the study.
If you want to see how good or band the air quality was at a particular time, simply draw a chart by choosing a type of particle from the drop-down menu.
This chart represents measurements of the sensors around Heathrow Airport in real-time.
To view the live data, choose a particle type you would like to view.

The more I learn about Java and Java-related technologies, the more I hate them. I am convinced that these things are developed by demons to torment righteous programmers.
My latest gripe is with Jelly, which advertises itself as “executable XML”. It flaunts this, in fact, as if it were actually a desirable feature. It’s like saying, “hey, look, we’ve got a burrito that you can actually drive!” Jelly, in my opinion, is one of the more insidious aspects of the Java world. It is finding its way into more and more widely-spread applications, most notably Maven.
If it weren’t for Maven, I’d never have to worry about Jelly. However, Maven uses Jelly to do all of its scripting. All of its plugins are built using Jelly, and if a developer wants to do any kind of custom task using Maven, it must be scripted using Jelly. I know this, because I was trying all morning to add a simple task to my Maven-based build system at work.
All I wanted was this: collect all of the variables in the Maven context, build them into a delimited string, and pass that string to an external program.
That’s all! And after a morning of wrestling with the Beast, I managed to turn out 15 lines of Jelly script that did just that. Doesn’t sound like much, does it? At least, not until you understand that the exact same functionality can be done in a mere 2 lines of Ruby code! And in writing those 15 lines of code, I came up with not one, not two, nor even three reasons why Jelly scripting ought to be made a punishable offense. I came up with eight reasons. That’s more than one reason per two lines of code.
So, in an effort to persuade the unpersuadable and bring those straying programmers back to the light, here are Eight Reasons Why Executable XML Is an Evil-Sick-Wrong-Misbegotten Idea.
You want to do a test on acouple of conditions to see if they are both true. In Java, the syntax for the and
conjunction is two ampersands, &&
. However, just you try and use that in a Jelly expression! Won’t work, because Jelly is XML, remember? And in XML, the ampersand is a reserved character. You have to escape the ampersands using XML entities, like so:
<jelly:if test="${something.isTrue() && somethingElse.isTrue()}"> ... </jelly:if>
if/else
LogicProgramming languages are all, generally-speaking, very much alike. Certain constructs are shared between many of them, and one of the most common of all is the if/elsif/else
construct. That’s a good thing because it makes it easier for a programmer who knows one language to learn another one, since much of the terminology carries right over.
 There is, it is true, an if
construct for Jelly. However, this construct has no else
clause. Thus, if you want to do an if/else
type of construct, you have to resort to one of two alternate approaches.
The first is to use two if
tags, the first testing for truth, and the second testing for falsehood, like this:
<jelly:if test="${something.isTrue()}"> ... </jelly:if> <jelly:if test="${!something.isTrue()}"> ... </jelly:if>
Ugly.
The second approach is to use the choose/when/otherwise
construct. (Great name, by the way. Took me a long time of just reading the docs to discover it, because it is sooo intuitive. Not.)
<jelly:choose> <jelly:when test="${something.isTrue()}"> ... </jelly:when> <jelly:when test="${somethingElse.isTrue()}"> ... </jelly:when> <jelly:otherwise> ... </jelly:otherwise> </jelly:choose>
Ohmygosh. Can we please try saying EVERYTHING EVERYTHING TWICE TWICE? This is one of my biggest gripes with the XML format in general, and why I much prefer the YAML format for things like configuration files. It is also why I think XML is a lousy choice for a programming language syntax.
<jelly:while test="..."> <jelly:if test="..."> <jelly:choose> <jelly:when test="${...}"> ... </jelly:when> <jelly:when test="${...}"> ... </jelly:when> <jelly:otherwise> ... </jelly:otherwise> </jelly:choose> </jelly:if> </jelly:while>
Error reporting in Jelly (and therefore Maven) is awful. Terrible. Miserable. Hateful. Evil.

For example:
<jelly:set var="variable" value="hello" /> <jelly:if test="${varable.equals('hello')}"> ... </jelly:if>
This will fail silently, leaving you wondering why the if statement isn’t being entered. Can you see the problem? Look carefully: the word “variable” is misspelled. And Jelly won’t tell you that; instead, it will just shrug it’s shoulders, mark the test as false, and move on. Thanks for that, Jelly. You somehow read my mind and discovered exactly what I didn’t want you to do.
Here’s an example of one that fails spectacularly:
<! -- returns an interator --> <jelly:set var="names" value="context.getVariableNames()" /> <jelly:while test="${names.hasNext()}"> <! -- throws ConcurrentModification exception! --> <jelly:set var="name" value="${names.next()}" /> </jelly:while>
There, where it calls names.next()
. Can you see what’s wrong? Can you figure out why an exception is thrown, which barfs all over my screen and gives me EVERYTHING AND HIS SORRY EXCUSE FOR A DOG back? Everything, that is, except what I really need to know, like why the script is failing in the first place.
Well, I’ll save you some grief and explain: it’s failing because on line 2, we grab an iterator that iterates over all of the variables in the current execution context. However, on line 5, we are creating a new variable in that context. This causes the iterator to complain about a concurrent modification. The solution? Declare “name” before you open the iterator. Thanks again, Jelly. You’re just lovely.
In C, C++, Ruby, Python, Perl, and yes, even Java, you embed control characters in strings using escaped character sequences. For example, a newline is a backslash followed by an n: \n
.
Is it this way in Jelly, our friendly executable XML syntax? Of course not. You have to use XML syntax for control characters. What is XML syntax for this? Why, XML entities, of course:
<! -- WRONG --> <jelly:set var="variable" value="first\nsecond" /> <! -- RIGHT --> <jelly:set var="variable" value="first second" />
To me, it looks like someone threw up in the middle of the string.
Forgive me, all you XML fans out there, but the XML comment is one of the ugliest structures on the planet:
<! -- here is the comment -->
Come on! At least make the comment delimiters brief! But no—it needs 4 characters to introduce the comment, and 3 characters to end it. And there is no such thing as a simple one-line comment in XML. In Java and C++ you can have all text to the end of the line ignored by typing two forward slashes: //
. Ruby, Perl and Python do even better and only require you to type a pound character: #
. XML requires you to type seven characters for every comment, no matter how small.
Before you can use certain Jelly tags, you have to declare and name the corresponding namespace. Only maven and ant tags are “globally” accessible, everything else you have to prefix with a namespace. This only compounds the problem of excessive verbosity and redundancy in the scripts. And “good programming style” expects you to include the namespaces of the maven and ant tags, even though they are automatically accessible.
<project xmlns:ant="jelly:ant" xmlns:jelly="jelly:core" xmlns:maven="jelly:maven" xmlns:util="jelly:util"> ... <jelly:if test="..."> </jelly:if> ... </project>
Jelly expressions are supposed to solve all problems, making life easier for developers. In practice, it is very frustrating to use them, since if you mistype something, you get no feedback indicating that (see the “error” issue above), and not all Java expressions are valid. It’s hard to know what expressions are acceptible and which aren’t, without actually trying it, and even then, you never know if you may have accidentally mistyped something and it would have worked if you’d typed it right.
For instance:
<! -- valid --> <jelly:set var="something" value="${context.getVariable('line.separator')}" /> <! -- invalid --> <jelly:set var="something" value="${System.getProperty('line.separator')}" />
Well, there you have it. I’m convinced. “Choose you this day whom ye will serve…but as for me and my house, we will serve the LORD.” Jelly is obviously a tool of Satan and I will therefore refuse to use it.
I’ll use Ruby, thank-you-very-much. It’s like a cool balm to a tortured programmer. If you have found yourself straying down the path of executable XML, it’s not too late to come back!

GLN_FILTER(1) |
|
GLN_FILTER(1) |
NAME
gln_filter - index/ignore classifier for glean
SYNOPSIS
gln_filter [-d] [config_file]
DESCRIPTION
gln_filter checks filenames against patterns in a configuration file. This is used to determine whether it should attempt to index files; it will also skip files contains a sufficiently large percentage of nonprintable data, but ruling out binary files via filenames is faster.
Options
|
-d |
Turn on debugging traces. |
|
(config_file) |
Use the specified configuration file. Used while testing by running gln_filter directly; to use a filter config file with gln_index, use the -f option. |
CONFIG FORMAT
Each line should contain a regular expression to match filenames, followed by a space, and then either "ignore" or "index". The first match wins, so early, specific patterns can override more general cases. If the regular expression contains a space, wrap it in quotes. Empty lines and lines beginning with '#' are ignored. For an example, see examples/example_filter_file (which also contains the defaults).
EXIT STATUS
gln_filter returns 0 on success or 1 on error.
SEE ALSO
glean(1), gln_index(1), re_format(7), gln(1).

| Prev | Up | Chapter 53. GIN Indexes | Next |
GIN stands for Generalized Inverted Index. It is an index structure storing a set of (key, posting list) pairs, where a "posting list" is a set of rows in which the key occurs. Each indexed value can contain many keys, so the same row ID can appear in multiple posting lists.
It is generalized in the sense that a GIN index does not need to be aware of the operation that it accelerates. Instead, it uses custom strategies defined for particular data types.
One advantage of GIN is that it allows the development of custom data types with the appropriate access methods, by an expert in the domain of the data type, rather than a database expert. This is much the same advantage as using GiST.
The GIN implementation in PostgreSQL is primarily maintained by Teodor Sigaev and Oleg Bartunov. There is more information about GIN on their website.


Lib Dems lose general election debate court battle to have Jo Swinson included
The party had said it was unlawful to not invite the Lib Dem leader to tomorrow's head to head debate
by Mikey Smith, https://www.mirror.co.uk/authors/mikey-smith/The Liberal Democrats have lost a High Court challenge to demand Jo Swinson be invited to tomorrow's head to head TV debate.
The Lib Dems and SNP brought a joint challenge against ITV over its decision to exclude their party leaders from the televised election debate.
Two leading judges ruled there was "no arguable breach of the Broadcasting Code".
Lord Justice Davis, sitting with Mr Justice Warby, said: "The clear conclusion of both members of this court is that, viewed overall, these claims are not realistically arguable.
"It follows that the television debate scheduled for tomorrow evening between the leader of the Conservative Party and the leader of the Labour Party may lawfully go ahead."
ITV is hosting a head-to-head debate between Boris Johnson and Jeremy Corbyn on Tuesday, which will not include any other party leaders.
Lib Dem representatives lodged papers at the court in London last week and said it was "vital for our democracy" to have both sides of the Brexit debate included in TV debates during the election campaign.
And Scottish First Minister Ms Sturgeon said last week that it is "fundamentally unfair" for other parties to be cut out of the debate.
Sky News has proposed a November 28 date for its debate, while the BBC has confirmed it will host two debates, on November 29 and December 6, in addition to a series of Question Time specials.

ARPING
Section: System Manager's Manual: iputils (8)Updated: 19 July 2011
Index Return to Main Contents
NAME
arping - send ARP REQUEST to a neighbour hostSYNOPSIS
arping [ -AbDfhqUV] [ -c count] [ -w deadline] [ -s source] -I interface destination
DESCRIPTION
Ping destination on device interface by ARP packets, using source address source.
OPTIONS
- -A
- The same as -U, but ARP REPLY packets used instead of ARP REQUEST.
- -b
- Send only MAC level broadcasts. Normally arping starts from sending broadcast, and switch to unicast after reply received.
- -c count
- Stop after sending count ARP REQUEST packets. With deadline option, arping waits for count ARP REPLY packets, until the timeout expires.
- -D
- Duplicate address detection mode (DAD). See RFC2131, 4.4.1. Returns 0, if DAD succeeded i.e. no replies are received
- -f
- Finish after the first reply confirming that target is alive.
- -I interface
- Name of network device where to send ARP REQUEST packets. This option is required.
- -h
- Print help page and exit.
- -q
- Quiet output. Nothing is displayed.
- -s source
-
IP source address to use in ARP packets.
If this option is absent, source address is:
-
- *
- In DAD mode (with option -D) set to <IP_ADDRESS>.
- *
- In Unsolicited ARP mode (with options -U or -A) set to destination.
- *
- Otherwise, it is calculated from routing tables.
-
- -U
- Unsolicited ARP mode to update neighbours' ARP caches. No replies are expected.
- -V
- Print version of the program and exit.
- -w deadline
- Specify a timeout, in seconds, before arping exits regardless of how many packets have been sent or received. In this case arping does not stop after count packet are sent, it waits either for deadline expire or until count probes are answered.

AUTHOR
arping was written by Alexey Kuznetsov<EMAIL_ADDRESS>It is now maintained by YOSHIFUJI Hideaki<EMAIL_ADDRESS>SECURITY
arping requires CAP_NET_RAWIO capability to be executed. It is not recommended to be used as set-uid root, because it allows user to modify ARP caches of neighbour hosts.
AVAILABILITY
arping is part of iputils package and the latest versions are available in source form at http://www.skbuff.net/iputils/iputils-current.tar.bz2.

Programming gives us the ability to complete tasks with Super Speed.
Software that enables machines to perceive their environment and make decisions with Insane Intelligence.
With Amazing Automation, we can use programming to automate and complete tasks without human intervention.
“That machine zeroes in on key words in a clue, then combs its memory (in Watson's case, a 15-terabyte data bank of human knowledge) for clusters of associations with those words. It rigorously checks the top hits against all the contextual information it can muster: the category name; the kind of answer being sought; the time, place, and gender hinted at in the clue; and so on. And when it feels "sure" enough, it decides to buzz. This is all an instant, intuitive process for a human Jeopardy! player, but I felt convinced that under the hood my brain was doing more or less the same thing.” -Ken Jennings

Address problems of workers, demands JAC
Employees’ associations stage protest in Vijayawada
by Staff ReporterDemanding that the government address the problems of workers in the State, the Joint Action Committee of teachers, employees, contract workers and pensioners will launch a State-wide protest on December 20 if the government fails to cater to their demands, said Krishna district JAC president A. Vidyasagar.
Addressing a protest staged collectively by various unions, under the aegis of the JAC, Mr. Vidyasagar said the YSRCP-led government had failed to address the problems of the workers despite being in power for six months.
Mr. Vidyasagar said that State government promised to scrap the Contributory Pension Scheme at the earliest, but failed to deliver on its promise. He highlighted that demands like the implementation of Pay Revision Commission, sanctioning of Dearness Allowance for employees and job security for contract workers had been pending with the State government for long.
The protesters demanded that the government extend free medical treatment for the workers instead of giving them health cards. They also pushed for the compulsory implementation of the PRC for the people working in gurukul model schools.

Steve Geisler owns two houses — one for himself and the other to rent out through Airbnb.
He purchased Creekside Cottage about three years ago, and it’s about a five-minute drive to Uptown.
He bought it from a man who was renting the house on Vacation Rental By Owner, a company that rents out houses and rooms for vacationers. Geisler also started renting it on Airbnb, but he said after he made that change he received three times more business than before.
“I took over everything he was doing. I even took his website and everything,” Geisler said. “I decided to go on Airbnb and that was like an explosion. All of the sudden I was being booked almost every single night, and it changed dramatically. It’s so busy.”
Airbnb prices range from $40 to $250, but some Airbnbs charge extra fees such as cleaning, bringing animals, service or number of guests. Owners choose the price they want to rent their house or room for. Airbnb also adds an additional fee for using the website. As of Jan. 15, there are 130 Airbnbs in Athens.
Geisler likes being his own boss and said he’s made friendships with his customers, sometimes grabbing a beer with them when they are back in town or texting them to catch up.
Geisler said the busiest times of the year are big weekends at Ohio University, such as Halloween or graduation. Eighty percent of his client base are parents.
“This year I noticed that right before school started there were tons of parents booking, probably coming down and settling their kids in,” Geisler said. “Right before school starts is a big time of year.”
The people who rent Airbnbs are not always parents, but also students, travelers, sightseers or even once a man coming to take a woman out on a date, Geisler said.
He’s had mostly positive experiences, he said, with an occasional bad one. The biggest problem has been people lying about how many are sleeping at the house to avoid a $25 fee for having more than two people. He’s also had someone break his hot tub.
Cleanliness is Geisler’s top priority for the house, because if something is dirty or weird, it will show up in reviews.
“As long as I make it a stellar experience and keep my prices low, it seems to keep me on top,” Geisler said. “It’s been absolutely fantastic, and I’ve done so well with it that I’ve been able to open up a couple more,” Geisler said. “I have two more that are just being built and about to be opened.”
Those other two are cabins Geisler created with Casey Buchanan. They co-own Morning Dew Hop Farm, a farm about 15 minutes away from Athens that grows organic hops and vegetables. Both decided to build three cabins for Airbnb on the property and upgrade one already standing.
“He and I invested into building three cabins at my farm. It’s been really successful having people in and out of there for the past three or four months,” Buchanan said.
Liz Chamberlain owns Bodhi Tree. It’s an Airbnb run out of her home. She rents by the room.
She started it a few years ago when she wanted to become a full-time yoga teacher and needed extra funds.
“I was making that transition, and it’s really hard to make a living as a yoga teacher,” Chamberlain said. “I found myself living in a home that had enough space to be opened up into an Airbnb and decided to do it.”
Chamberlain said she chose to transition from a bed and breakfast, as she had originally started it as, to an Airbnb because it made booking easier and was popular.
Alex Penrose | MULTIMEDIA DIRECTOR
“We were sort of hoping because our business is different than the traditional bed and breakfast, we were hoping to attract a different customer base,” Chamberlain said. “A lot of the people we were getting prior to that were older people that loved bed and breakfasts, and it wasn’t really our vibe.”
There is still room to grow, Chamberlain said, but she’s happy with it. She has a steady flow of guests and is able to own a yoga studio.
“It’s been a great addition to our business and helps us support doing other things we like to do,” Chamberlain said.
She said she doesn’t compare herself to other Airbnbs in Athens. She tends to be higher priced than most but doesn’t focus on competition.
“I keep in mind what it costs to stay at a hotel. We are lower, but not that much lower,” Chamberlain said. “I try to be fair to myself as the person that does most of that work for what I have to put into even for just hosting one person for one night. I feel good about what we charge right now, and the guests feel good about it so I work from that.”
Airbnbs within Athens are only permitted in zone R-2 (one to two family housing zone) and zone R-3 (multifamily housing zone), according to a 2016 Athens City Council ordinance. Those are houses and buildings built to house one or more families. Those who try to open an Airbnb within those zones will be shut down for code violation.
“They’re allowed in certain areas in the city but not all,” Chris Knisley, Athens City Council president, said.
Knisley said the ordinance will likely be reevaluated in the future as it has become outdated from the growth of Airbnb in Athens.
Ashton Nichols | SENIOR WRITER
Athens Township and County are allowed to tax hotel or home lodging up to 3 percent, according to the Ohio Revised Code. Each transaction is taxed 3 percent of the profits.
Eight owners are currently paying the tax, as of Jan. 8., according to the Athens County Auditor’s Office. Four businesses paid it last year.
The Athens County tax was implemented in the ‘90s, Chris Chmiel said, and the profits of the lodging tax go to the Athens County Convention and Visitors Bureau. Chmiel, an Athens County commissioner, said most Airbnb owners do not pay the tax.
“People start this Airbnb thing, but they necessarily don’t realise there’s a lodging tax that needs to be paid,” Chmiel said.
Geisler chooses to pay the tax because he does not know what will happen if he does not.
“It’s kind of voluntarily now, and I pay it because I don’t want any trouble and want to do everything right,” Geisler said. “I don’t mind it. I’m not big on handing out money, but it’s part of doing business. Every other place has to do it. It goes to something. I can’t really complain about 3 percent. I just do it to contribute back into the community.”
Chmiel himself has an Airbnb and said he will talk to other owners about paying it. He said people may just not be aware.
“I will say that when we started talking about this, several more Airbnbs have started to pay the tax,” Chmiel said.
Because so few owners pay the tax, Athens County sent a letter to Airbnb to request that the lodging tax automatically be included in fees. That is done in different states and larger cities in Ohio.
“What we’d like them to do is to automatically collect the tax when there is a transaction,” Chmiel said. “It makes it easier for the Airbnb owners, and then we make sure that money is being collected and the county takes it.”
Chmiel pays the lodging tax for his Airbnb, Integration Acres Farm, a farm located in Albany. He started it a couple years ago when Airbnb first became popular.
“It has been fun,” Chmiel said. “We’ve had people from all over the country. It’s worked out for us, and I think it’s worked out for a lot of people.”
Chamberlain said she chooses to pay the lodging tax as well. The Athens County Visitors Bureau advertises her business on their lodging page, which makes her feel like it is worth it, she said.
“We used to be on the homepage and a lot of people found us that way,” Chamberlain said.
“We felt like we got a lot of good advertising from them. Maybe you get a little bit used to it as a small business person (because) there are taxes wherever you look.”
Andie Walla, a media arts and studies professor at OU, owns Wallahalla, an Airbnb.
She hires someone to do her taxes locally. She said she has had to lower her prices to compete with other Airbnbs in Athens because the market is saturated, but then loses profits when she is taxed.
“Higher prices across the board, doesn't encourage more folks to visit Athens. I hope Athens is able to have Airbnb add the taxes in on their website,” Walla said in an email. “That way we won't have to deal with it.”
Buchanan said he pays the tax for his Airbnb because he’s happy to support local communities through the money that is earned from it.
“We don’t have a problem paying taxes,” Buchanan said. “We’re happy to give as much money as possible to them to help build up our area and strengthen our community.”
The Athens County Convention and Visitors Bureau receives 50 percent of the city lodging tax profits and 95 percent of the Athens County tax lodging profits.
Paige Alost, executive director of the bureau, said she is not involved in the collection of the tax but in making sure the investment benefits Athens County.
“That money comes to us and we use the money to promote Athens county as a destination for visitors,” Alost said. “That money gets spent not just in staff, but also in advertising and marketing and promotion and trade shows.”
Alost said she aims to have visitors stay overnight because they will spend more money, which is why some Airbnbs are promoted on the bureau’s website.
“In our last economic impact report, Athens county tourism generated $166 million impact for our county,” Alost said. “The majority of that, about 80 percent of that, comes from day visitors.”
Geisler said his only concern is taxes do add up, because he also pays income taxes to the state, along with other fees of being a business owner.
“It’s not just 3 percent. There’s more to it,” Geisler said. “I don’t think everybody’s playing by the book, but I am.”
Chmiel predicts Airbnb will one day outgrow the Athens market and have too many in one location.
“I think at some point there will be a saturation in the market,” Chmiel said. “We’re only going to be able to support so many Airbnbs. I like it though because it’s a distributed economy.  It’s a lot of little people making money.”

When i got this option active i think will be better if any of the 2 options (1-Goto first page of this thread / 2-Goto last page of this thread) would open in a new window, not in the same, sometimes is getting annoying going back to get the list of thread.
Thanks.

Most people not want this - And the people that open in new tab press the middle mouse button.
Mostly every link opens in the same window in battlelog, break with this rule is not fine.


It still doesn't work. :(
About twenty minutes in, I got the socket working, but hit an error where after a single round trip the socket would close. Another twenty minutes, I went home. When I started up the server again, the socket wasn't working with the same KeyError wsgi.websockets issue again. And now I can't fix it.
I told myself I needed to commit something every day before midnight, so that's why I'm here rushing this out. This is frustrating, though. Maybe I'll move away from Python entirely.
Update: 40 more minutes later, it works! I just needed to throw the logic in a loop, instead of blindly relying on gunicorn to handle keeping the socket open. So now we're finally in good shape.
