8 Basic Fisheries Statistics
8.1 Calculating Landings
One of the first analyses you may be interested in is calculating annual landings in the fishery. To calculate annual landings, take your landings_data
data frame, add a column for weight of individual fish in kilograms by using the mutate
function, group the data by year by using the group_by
function, and then summarize the data for each year by summing the total weight of all fish caught in each year using the summarize
and sum
functions.
# Start with the landings data frame
annual_landings <- landings_data %>%
# Add colomn for kilograms by dividing gram column by 1000
mutate(Weight_kg = Weight_g / 1000) %>%
# Group the data by year
group_by(Year) %>%
# Next, summarize the total annual landings per year
summarize(Annual_Landings_kg = sum(Weight_kg,na.rm=TRUE))
## Display a table of the annual landings data
annual_landings
## # A tibble: 9 x 2
## Year Annual_Landings_kg
## <int> <dbl>
## 1 2003 310.40914
## 2 2004 565.30807
## 3 2005 163.24191
## 4 2006 37.11914
## 5 2010 131.84178
## 6 2011 156.77825
## 7 2012 101.53198
## 8 2013 579.52008
## 9 2014 1193.75519
Note the use of na.rm = TRUE
in the code above. This is an important argument of many R functions (sum()
in this case) and it tells R what to do with NA
values in your data. Here, we are telling R to first remove NA
values before calculating the sum of the Weight_kg
variable. By default, many functions will return NA
if any value is NA
, which is often not desirable.
You may be interested in looking at landings across different gear types. Here, we now group the data frame by both the year and the gear type in order to summarize the total landings by year and by gear.
# Start with the landings data frame
annual_gear_landings <- landings_data %>%
# Add colomn for kilograms by dividing gram column by 1000
mutate(Weight_kg = Weight_g / 1000) %>%
# Group the data by year and gear type
group_by(Year,Gear) %>%
# Next, summarize the total annual landings per year and gear type
summarize(Annual_Landings_kg = sum(Weight_kg,na.rm=TRUE))
## Display a table of the annual landings data by gear type
annual_gear_landings
## # A tibble: 39 x 3
## # Groups: Year [?]
## Year Gear Annual_Landings_kg

## 9 2004 trap 118.683464
## 10 2004 trolling 4.386547
## # ... with 29 more rows
8.2 Calculating Catch-per-Unit-Effort (CPUE)
You may also be interested in calculating catch-per-unit-effort (CPUE). CPUE is calculated by dividing the catch of each fishing trip by the number of hours fished during that trip. This gives CPUE in units of kilograms per hour. The median for every year is then calculated in order to remove outliers - some fishers are much more efficient than others.
# Start with the landings data frame
cpue_data <- landings_data %>%
# Add colomn for kilograms by dividing gram column by 1000
mutate(Weight_kg = Weight_g / 1000) %>%
# Group by year and Trip ID so that you can calculate CPUE for every trip in every year
group_by(Year,Trip_ID) %>%
# For each year and trip ID, calculate the CPUE for each trip by dividing the sum of the catch, converted from grams to kilograms, by the trip by the number of fishing hours
summarize(Trip_CPUE = sum(Weight_kg) / mean(Effort_Hours)) %>%
# Next, just group by year so we can calculate median CPUE for each year across all trips in the year
group_by(Year) %>%
# Calculate median CPUE for each year
summarize(Median_CPUE_kg_hour = median(Trip_CPUE))
# Display a table of the CPUE data
cpue_data
## # A tibble: 9 x 2
## Year Median_CPUE_kg_hour
## <int> <dbl>
## 1 2003 0.31834277
## 2 2004 0.26233292
## 3 2005 0.40145105
## 4 2006 0.44029501
## 5 2010 0.01742840
## 6 2011 0.03123217
## 7 2012 0.03123217
## 8 2013 0.19638408
## 9 2014 0.88216281
8.3 Calculating Percent Mature
You may also wish to analyze your length data. One analysis would be to determine the percentage of mature fish in the catch in every year of the data frame. First let’s define m95
, the length at which 95% of fish are mature. For Caesio cuning, we know this is 15.9cm. Next, let’s add a column to the data frame using the mutate
function that represents whether each fish is mature or not (represented by a TRUE
or FALSE
), group the data frame by year, and then summarize for each year the percentage of mature fish out of the total number of sampled fish.
# Define m95, the length at which 95% of fish are mature
m95 = 15.9
# Start with the landings data frame
landings_data %>%
# Add a column to the data that indicates whether each length measurement is from a mature or immature fish. If it's mature, this value should be TRUE; if immature, FALSE.
mutate(Mature = Length_cm > m95) %>%
# Group by year so we can see the percent mature for every year
group_by(Year) %>%
# The percentage mature is equal to the number of mature fish divided by the total number of fish and multiplied by 100
summarize(Percent_Mature = sum(Mature) / n() * 100)
## # A tibble: 9 x 2
## Year Percent_Mature
## <int> <dbl>
## 1 2003 98.56916
## 2 2004 98.62188
## 3 2005 97.73371
## 4 2006 100.00000
## 5 2010 91.80556
## 6 2011 99.77629
## 7 2012 99.65398
## 8 2013 99.46164
## 9 2014 99.55665
Over 90% of the fish are mature throughout the time series, which is a great sign!

We will use both a coarse selection filter and in a later step, a fine universe filter, to narrow down our universe of assets. Our coarse universe filter creates a set of stocks based on volume, price, and whether fundamental data on the stock exists. In this step we filter for the top 100 liquid equities with prices greater than $5. We also exclude the equities missing fundamental data because EPS is needed in the fine selection step.
def CoarseSelection(self, coarse): ''' Pick the top 100 liquid equities as the coarse-selected universe ''' # Before next rebalance time, just remain the current universe if self.Time < self.nextRebalance: return Universe.Unchanged # Sort the equities (prices > 5) by Dollar Volume descendingly selectedByDollarVolume = sorted([x for x in coarse if x.Price > 5 and x.HasFundamentalData], key = lambda x: x.DollarVolume, reverse = True) # Pick the top 100 liquid equities as the coarse-selected universe return [x.Symbol for x in selectedByDollarVolume[:self.numOfCoarse]]
N.Jegadeesh et al. state price momentum and earnings momentum can be used as two indicators for trading. We will calculate for price momentum with the "GetQuarterlyReturn" method and for earnings momentum with the "GetEarningGrowth" method.
"GetQuarterlyReturn" calculates price momentum for each symbol in our coarse universe and ranks each stock based on its quarterly return. First we request last quarter’s close price for all stocks. Then we calculate quarterly return by taking the delta of the first day’s close price and the last day’s close price. Finally, we store the symbols and their corresponding rankings by quarterly return in a dictionary in preparation for fine selection.
def GetQuarterlyReturn(self, history): ''' Get the rank of securities based on their quarterly return from historical close prices Return: dictionary ''' # Get quarterly returns for all symbols # (The first row divided by the last row) returns = history.iloc[0] / history.iloc[-1] # Transform them to dictionary structure returns = returns.to_dict() # Get the rank of the returns (key: symbol; value: rank) # (The symbol with the 1st quarterly return ranks the 1st, etc.) ranked = sorted(returns, key = returns.get, reverse = True) return {symbol: rank for rank, symbol in enumerate(ranked, 1)}
"GetEarningGrowth" calculates earnings momentum for each symbol in our coarse universe and ranks each stock based on its earnings growth. First we use a RollingWindow to store and update the BasicEPS to reflect quarterly earnings reports. A RollingWindow holds a set of the most recent entries of data. As we move from time t=0 forward, our rolling window will shuffle data further along to a different index until it leaves the window completely. The object in the window with index[0] refers to the most recent item. The length-1 in the window is the oldest object.
Our rolling window has a length of 2 so index[0] is the current EPS and index[1] is last quarter's EPS. We calculate earnings growth for each stock by taking the delta of this quarter’s EPS and last quarter’s EPS divided by last quarter’s EPS. Finally we rank each asset based on earnings growth.
def GetEarningGrowth(self, fine): ''' Get the rank of securities based on their EPS growth Return: dictionary ''' # Earning Growth by symbol egBySymbol = {} for stock in fine: # Select the securities with EPS (> 0) if stock.EarningReports.BasicEPS.ThreeMonths == 0: continue # Add the symbol in the dict if not exist if not stock.Symbol in self.epsBySymbol: self.epsBySymbol[stock.Symbol] = RollingWindow[float](2) # Update the rolling window for each stock self.epsBySymbol[stock.Symbol].Add(stock.EarningReports.BasicEPS.ThreeMonths) # If the rolling window is ready if self.epsBySymbol[stock.Symbol].IsReady: rw = self.epsBySymbol[stock.Symbol] # Caculate the Earning Growth egBySymbol[stock.Symbol] = (rw[0] - rw[1]) / rw[1] # Get the rank of the Earning Growth ranked = sorted(egBySymbol, key = egBySymbol.get, reverse = True) return {symbol: rank for rank, symbol in enumerate(ranked, 1)}
We use a fine selection filter in addition to a coarse selection filter to refine our asset selection based on corporate fundamental data. We can use both quarterly return and earnings growth from our two indicators to generate an average rank for each stock. Then we can go long on the top 10 and short the bottom 10.
def FineSelection(self, fine): ''' Select securities based on their quarterly return and their earnings growth ''' symbols = [x.Symbol for x in fine] # Get the quarterly returns for each symbol history = self.History(symbols, self.rebalanceDays, Resolution.Daily) history = history.drop_duplicates().close.unstack(level = 0) rankByQuarterReturn = self.GetQuarterlyReturn(history) # Get the earning growth for each symbol rankByEarningGrowth = self.GetEarningGrowth(fine) # Get the sum of rank for each symbol and pick the top ones to long and the bottom ones to short rankSumBySymbol = {key: rankByQuarterReturn.get(key, 0) + rankByEarningGrowth.get(key, 0) for key in set(rankByQuarterReturn) | set(rankByEarningGrowth)} # Get 10 symbols to long and short respectively sortedDict = sorted(rankSumBySymbol.items(), key = lambda x: x[1], reverse = True) self.longSymbols = [x[0] for x in sortedDict[:10]] self.shortSymbols = [x[0] for x in sortedDict[-10:]] return [x for x in symbols if str(x) in self.longSymbols + self.shortSymbols]
We choose to rebalance every quarter and use equal weights for the long and short positions of securities in our portfolio.
def OnData(self, data): ''' Rebalance quarterly ''' # Do nothing until next rebalance if self.Time < self.nextRebalance: return # Liquidate the holdings if necessary for holding in self.Portfolio.Values: symbol = holding.Symbol if holding.Invested and symbol.Value not in self.longSymbols + self.shortSymbols: self.Liquidate(symbol, "Not Selected") # Open positions for the symbols with equal weights count = len(self.longSymbols + self.shortSymbols) if count == 0: return # Enter long positions for symbol in self.longSymbols: self.SetHoldings(symbol, 1 / count) # Enter short positions for symbol in self.shortSymbols: self.SetHoldings(symbol, -1 / count) # Set next rebalance time self.nextRebalance += timedelta(self.rebalanceDays)

Sorting (merge sort, quick sort, bubble sort)
Often we need to sort data as part of our processing logic, and it is also a common interview question to construct a sort. There various methods to generate a sorted list of items. In this post I will take a look at sorting array data with Ruby. I will look at merge sort, quick sort and the bubble sort.
Merge Sort - This sort methods works by dividing the array into the smallest unit (1 element), then compare each element with the adjacent list to sort and merge the two adjacent lists. When the sorting and merging is completed you have the sorted array. A short example of a merge sort can be found here: https://gist.github.com/kimhunter/1284454 and is presented below.
def merge_sort(array)
return array if array.size <= 1
l, r = split_array(array)
# Here we are going to recursively call merge_sort
# until all elements are split out
# Then merge them back in to one sorted array via #combine
result = combine(merge_sort(l), merge_sort(r))
end
def split_array(array)
# find the mid point of the array
mid = (array.size / 2).round
# return 2 arrays. One of the first half of the array,
# and one of the second half
[array.take(mid), array.drop(mid)]
end
def combine(a, b)
# return either a if b is empty or b if a is empty
return b.empty? ? a : b if a.empty? || b.empty?
# Smallest is either the first element of a or b whichever is smaller
# Then remove that element from the array it came from; either a or b
smallest = a.first <= b.first ? a.shift : b.shift
# Make a recursive call to combine with the remaining array elements
# Prepend our smaller value to the front of the resulting array returned
combine(a, b).unshift(smallest)
end
# Driver code
a = [6,23,53,1,2,5,62,61,33,21,14,6,23].shuffle
p a # => [61, 21, 23, 6, 33, 5, 53, 6, 62, 14, 23, 1, 2]
p merge_sort(a) # => [1, 2, 5, 6, 6, 14, 21, 23, 23, 33, 53, 61, 62]
Quick Sort - A quick sort is a sorting method that works by selecting a "pivot" element of the array and then roughly sorts the other elements relative to the pivot. The smaller value elements are placed before the pivot and the higher value elements are placed after the pivot. This process is repeated across the array recursively.
def quick_sort(array)
return array if array.length <= 1
pivot = array.sample # pick a random element for the pivot
array.delete_at(array.index(pivot)) # remove the pivot
#puts "Picked pivot of: #{pivot}"
lesser = []
greater = []
# divide the array into lesser than pivot and a greater than pivot arrays
array.each do |x|
if x <= pivot
lesser << x
else
greater << x
end
end
# build our sorted array
sorted_array = []
# recursively sort the lesser array values
sorted_array << quick_sort(lesser)
sorted_array << pivot # add our pivot value
# reccursively sort our greater array
sorted_array << quick_sort(greater)
# flatten out our resulting array and return this
sorted_array.flatten!
end
# Driver code
a = [6,23,53,1,2,5,62,61,33,21,14,6,23].shuffle
p a # => [61, 21, 23, 6, 33, 5, 53, 6, 62, 14, 23, 1, 2]
p quick_sort(a) # => [1, 2, 5, 6, 6, 14, 21, 23, 23, 33, 53, 61, 62]
Bubble Sort - A bubble sort is a simple method that works by repeatedly stepping through the array, comparing each pair of adjacent items and swapping them if they are in the wrong order. The sorting passes through the array are repeated until no further swaps are needed. For a large set of data, it is easy to see that this method could take a long time to process.
def bubble_sort(array)
return array if array.size <= 1
swapped = true # this flag indicates we did a swap, and we need to loop again
while swapped do
# set the flag to false so we can break out of this loop if there was no swap
swapped = false
# loop trough the array from first element to the next to last element
0.upto(array.size-2) do |i|
# if the value is greater than the next value, swap them
if array[i] > array[i+1]
array[i], array[i+1] = array[i+1], array[i]
swapped = true # set the flag since we swapped
end
end
end
# return back the sorted array
array
end
# Driver code
a = [6,23,53,1,2,5,62,61,33,21,14,6,23].shuffle
p a # => [61, 21, 23, 6, 33, 5, 53, 6, 62, 14, 23, 1, 2]
p bubble_sort(a) # => [1, 2, 5, 6, 6, 14, 21, 23, 23, 33, 53, 61, 62]


French tourist killed taking selfie at Thai waterfall
A French tourist has died after falling from a waterfall while trying to take a selfie in Thailand, police said Friday.
The accident happened Thursday afternoon on the tropical island of Koh Samui, whose palm-fringed, white-sand beaches are a magnet for both backpackers and high-end tourists.
The 33-year-old man fell from Na Mueang 2 waterfall, the same spot where a Spanish tourist died in a fall in July, Lieutenant Phuvadol Viriyavarangkul of the island’s tourist police told AFP.
“It took several hours to retrieve his body because the waterfall is slippery and steep,” he said by phone, adding that the spot is roped off and there is a sign warning tourists of the danger.

Thailand is largely considered a safe destination for tourists and typically draws more than 35 million visitors each year.
But the industry took a hit in 2018 after a ferry carrying Chinese visitors in the country’s south sank last year, killing 47 people.
The accident highlighted lax safety rules in the tourism sector and authorities have been scrambling to restore the country’s image since. AFP

Identity, Values and Strengths Exploration
I've been thinking a lot about values in terms of previous companies that I have work with and the values that I have looked for in them to determine whether I would enjoy working there and be a good fit. I think this has really helped me in the past to figure out the culture of a place that I would be working for but in terms of my identity I think it has been the most important for my values to align with them. For me I think what comes top of mind for values is honesty, passion and growth. Honesty I value as important for open communication, passion is important for me in going after what I enjoy and am excited about in life and growth in terms of always learning and evolving.
I'm attending Dev Academy because I was after a new challenge within my digital career and a friend who is a QA tester recommended it to me. I've always been interested in coding and am intrigued to see where this path takes me. I was also working for Canada Learning Code whilst in Toronto and loved the environment and people there that it made me want to follow this path even more.
My top values and what I continue to look for in life are:
Helping people
Continuiously looking for learning and growth opportunities
Develop new skills from mentors and people that are more knowledgable than me
Honesty and integrity
Being Genuine and acting with good intentions towards others
I tend to really respect and get along with people who are open minded and except peoples differences. I think it's important to feel comfortable in a work environment and whilst working with collegues to be able to express yourself and what you need to get the task done. This is also vitual when hoping to gain support and feedback for working in development. As a junior web developer I will need support and guidance from a mentor/senior developer until I feel that I know the code base and feel comfortable with the work I am coding in order to gain the desired outcome.

The tracing support is added using OpenTelemetry-cpp.
There are two types of spans:
Library generated spans:
Send span ("amqp-message-send”) gets created just before sending a message and ends when that message gets settled. Receive span ("amqp-message-received") gets created just before receiving a message and ends as soon as the message is received. 2. Application generated spans: Users can also create their own spans and those spans will get linked with the library generated spans. @subsection autotoc_md12 Usage: @subsubsection autotoc_md13 1. Initialize the exporter @iverbatim opentelemetry::exporter::jaeger::JaegerExporterOptions opts; std::unique_ptr<opentelemetry::sdk::trace::SpanExporter> exporter = std::unique_ptr<opentelemetry::sdk::trace::SpanExporter>( new opentelemetry::exporter::jaeger::JaegerExporter(opts)); @endiverbatim Above is an example of initializing a jaeger exporter. Apart from jaeger exporter, there are many other exporters supported by OpenTelelemetry. @subsubsection autotoc_md14 2.

Hand Potential.
Hand Potential is the calculation of the probability
that a hand that is currently behind will be ahead as more
board cards are dealt. Negative Potential (NPOT) is the
probability that given that we are currently ahead, future
cards will put is behind.
Contains the Hand Potential Calculations as described in:
Dealing with Imperfect Information in Poker.

The lean-3.4.2
tag branch seems to have fallen behind master
.
We don't use the tag anymore. We use a branch. We've tried over and over to delete the tag but people have a copy on their hard drive and keep pushing it
The head of the lean-3.4.2
branch is 19 hours old so it's up to date
Oh, sorry, I meant branch rather than tag --- I guess I was expecting it to catch up to master more quickly. Is this just travis being slow? I'm curious that it has more work to do after the merge with master.
It's merged once a day
Would it be possible to merge more often? When PRs are coming in from other repositories, part of the workflow is:
1) PR gets merged to mathlib
2) Go back to other repository, leanpkg upgrade
, update-mathlib
, and fix up as required.
3) Realise update-mathlib
doesn't work yet, and committing the result of leanpkg upgrade
will upset collaborators
4) Decide to wait a day
5) Forget what you're doing
Scott, I'm a bit confused. I think the only reason why we don't update more often is because we wait for the hosting you promise you would be able to offer
Ah, okay. The hosting is definitely available. The question is how to get stuff to it.
I would prefer that travis doesn't have push access to my server.
This is what I meant by waiting for hosting. I meant waiting for you to figure out how you want to do it
So the options were:
1) I can pay for amazon s3 hosting (as I already do, and this won't be much additional), but someone would have to write a script that posted stuff to it.
2) I can run a cron job on my server that pulls something that travis produces.
My scripting-fu, particularly once it involves pushing files around, is not very good, and I don't understand the travis workflow completely.
So I wasn't thinking this was something on my todo list. I was waiting for someone to hand me a script to add to cron
on my server. :-)
I wonder if we are not complicating things by insisting we should reuse Travis work
If you have computing power you could also compile on your end, and bypass Travis
Your machine can periodically ask GitHub for new commits (this is trivial compared to anything involving Travis)
OK: I propose that the following is the easiest to implement (but maybe wasteful of CPU time):
while (true) checkout all branches of leanprover-community/mathlib run `cache-olean --build-all` copy the contents of the `_cache` directory to a webserver
That should be easy to implement (probably in four lines!)
Is it actually useful? i.e. can someone work out what URL they need to fetch?
Yes I think this would be very useful. cache-olean
produces file names directly from the git SHA so there would be no issue guessing urls
We need to check that cache-olean is smart enough to avoid recompiling a commit it already has. Otherwise you'll need to add another line to your loop
@Scott Morrison At which base URL would you want to serve the caches? I think we can easily update the dev-scripts to point to that URL
It will probably be https://tqft.net/lean/mathlib/_cache/
. I will try to set this up today.
Getting there: https://tqft.net/lean/mathlib/
It's not in a crob job yet, but I have a script that seems to do everything required.
crontab -e
*/10 * * * * command to execute
It should probably be integrated into cache-olean
Do we want a more catchy name than "Scott's server"?
That's quite an accurate name, I would say...
Alternative catchy names: kangaroo
, sandbox
, scuba
, hey_mate
I like kangaroo
and hey_mate
but what if Scott gets sick of taking care of it and it moves (say) to Germany?
bradwurst
?
We could rename it to weizen_bier
Two good choices, I see
We could call it carmen_sandiego
in anticipation of it moving around :P
(a hot dog is not a bradwurst but I'm just happy you didn't say saurkraut
)
My compiler is running into trouble on some branches. e.g. the calculus
branch has lots of errors, and it takes a while to run (even on subsequent runs of leanpkg build
)...
Not sure what to do about that.
I guess I really need to set things up so that I only rebuild branches that have new commits, rather than just trying to build everything. :-)
That sounds like a good idea
@Simon Hudon, any ideas how to achieve that? I would like to go into each branch, and decide if there has been a new commit since the last time the olean cache file for that branch was built.
I guess you can also kill compiles that are taking a very long time (like Travis does)
oh.... I'm dumb.
Are the cache files just named after the commit hash?
I think so, yes
They are
My idea would be to just have travis push its build results
Travis does a lot of work already, reusing it can some you a bunch of trouble
That sounds great too. However, I didn't want to learn how to make travis push to my machine or S3. :-)
I can give you hand. But for now, it's time for bed
@Scott Morrison How do you access your S3 account?
Using the secret access key. I think at some point I sent you another one.
Okay, https://tqft.net/lean/mathlib/ seems to be working. It polls github once a minute, compiles any new commits, and posts olean caches.
@Scott Morrison Cool! Thanks a lot for this effort
Coming soon in cache-olean
: a link to https://tqft.net/lean/mathlib/
@Simon Hudon I am having such trouble with git. What should I be doing to pull every branch??
Ahh... maybe worked it out.
Let me try one more time, after which I will send you my build script and some logs :-)

--- title: Post-Mortems at HubSpot -- What I Learned From 250 Whys layout: post ---
At HubSpot, for the past two years, we've modeled our post-mortems on Eric Ries's 5 Whys. When we started, I served as the facilitator for basically all of them -- over time, we've added other folks into that role.
It's been a deeply interesting learning experience.
Great stuff in here. Many follow-on links opened from this article ;-)

Outlook 2007 works fine in Vista, no problems. Just check all add/plug ons/ins etc. ---
I like Office 2007, and even though the early betas were very shaky, it is now fairly reliable. The one exception was Outlook 2007, which I used all throught the beta day to day without too many issues (except for it being really slow and heavy at times).
Unfortunately, I've been far less lucky since Office 2007 was released and I installed it on Vista. For some reason I still haven't figured out, Outlook 2007 crashes on me regularly while trying to compose an email (either new or a response to another email). It does not seem to matter if the email is rich text, HTML or text, for that matter.
For example, today it has already crashed three times. Anyone has any ideas as to what may be causing this?


Adding accounts: When adding your first account, simply click "Add User" while signed in on dmoj. When adding more accounts, you must click "Add User". You will then be redirected to the sign in page, and you can sign in. After, click "Add User" again to add your new account.
Updaing accounts: If the stored cookied ever becomes invalidated, you can update the account by right clicking the account while signed in. If multiple cookies become invalid, click "Add Account" and sign into your new account. After, you can right click the account.
Why so complicated?
This extension works by storing cookies of sessions, and restoring them when switching accounts. When you log out, this token is invalidated. To prevent this, clicking "Add Account" will remove the session cookie instead of invalidating it. This keeps previously stored cookies valid.


If a template keyword name ends with a "#" character, it is said to be 'auto-indexed'. Each "#" character will be replaced by the current integer index value, which gets reset = 1 at the start of each new HDU in the file (or 7 in the special case of a GROUP definition). The FIRST indexed keyword in each template HDU definition is used as the 'incrementor'; each subsequent occurrence of this SAME keyword will cause the index value to be incremented. This behavior can be rather subtle, as illustrated in the following examples in which the TTYPE keyword is the incrementor in both cases:
TTYPE# = TIME TFORM# = 1D TTYPE# = RATE TFORM# = 1Ewill create TTYPE1, TFORM1, TTYPE2, and TFORM2 keywords. But if the template looks like,
TTYPE# = TIME TTYPE# = RATE TFORM# = 1D TFORM# = 1Ethis results in a FITS files with TTYPE1, TTYPE2, TFORM2, and TFORM2, which is probably not what was intended!

Urban Meyer Has Hilarious Response To Minnesota’s Loss To Iowa
by Andrew McCartyFormer Ohio State head coach Urban Meyer left the sideline for the broadcast booth following the 2018 college football season.
Meyer is a standout analyst for FOX Sports and frequently makes visits on the Big Ten Network to break down games from the previous weekend.
Arguably the game of most consequence last weekend in the Big Ten occurred at Kinnick Stadium as the Iowa Hakweyes handed the Minnesota Gophers their first loss of the season.
P.J. Fleck’s team had dreams of a potential College Football Playoff berth, but the loss to Iowa makes that dream much more difficult.
Meyer is familiar with heartbreaking losses at Kinnick Stadium with a playoff berth on the line – and he’s very aware of that.
When asked about Minnesota’s loss, Meyer said he knows Iowa well.
“They played a good team. We all know Iowa. Shoot, I know Iowa,” Meyer said about the Hawkeyes this week.
Check it out.
Meyer and the Buckeyes had dreams of a College Football Playoff berth during the 2017 season. However, a trip to Kinnick Stadium resulted in a 55-24 loss for Ohio State – which ultimately cost the team a shot at the playoff.
Meyer has to be happy with where the Buckeyes stand now, though.

HARRISBURG, PA., October 22, 1862. (Received 2.30 p. m.)
Honorable E. M. STANTON, Secretary of War:
The draft is being resisted in several counties of the State. In Schuylkill County I am just informed that 1,000 armed men are assembled, and will not suffer the train to move with the drafted men to this place. I wish ample authority to use my troops in the State, and particularly the regulars and Anderson Cavalry at Carlisle, to crush this effort instantly. We will thus enforce the law, and effectually, if successful, prevent the like occurring in other parts of the State.
Please answer promptly.
A. G. CURTIN, Governor of Pennsylvania.
WASHINGTON, October 22, 1862-8 p.m.
Governor CURTIN:
You are authorized to employ the regular force, the Anderson Cavalry, and any other military force in your State to enforce the militia draft, and also to call upon Major-General Wool, the commanding general of the Middle Department, for aid, if you desire it. He has been instructed to support you with the whole force of the department.
EDWIN M. STANTON, Secretary of War.
WAR DEPARTMENT, Washington City, October 23, 1862.
Major-General HALLECK, General-in-Chief:
GENERAL: The inclosed telegram from Governor Curtin is referred to you, with instructions to give such directions in relation to the employment of troops, and affording military aid for the enforcement of draft, as you may deem proper.
Your obedient servant,
EDWIN M. STANTON, Secretary of War.
[Inclosure.]
HARRISBURG, October 23, 1862-12.15 p.m.
Honorable E. M. STANTON, Secretary of War:
Notwithstanding the usual exaggerations, I think the organization to resist the draft in Schuylkill, Luzerne, and Carbon Counties is very formidable. There are several thousands in arms, and the people who will not join have been driven from the county. They will not permit the drafted men, who are willing, to leave, and yesterday forced them to get out of the cars. I wish to crush the resistance so effectually that the like will not occur again. One thousand regulars would be most efficient, and I suggest that one [regiment?] be ordered from the army. General A. Porter, who is here, and fully informed, agrees with me, and advises the employment of such a force.
I am getting volunteer troops ready.
Let me hear immediately.
A. G. CURTIN, Governor of Pennsylvania.
WASHINGTON, October 23, 1862-3 p.m.
Governor CURTIN:
By my telegram of last evening, you were authorized to employ all the military force in your department to enforce the draft, and General Wool was also directed to aid you upon your requisition. I am not aware of any further assistance that can be required or given by the Department. Your request for 1,000 regulars has been referred to the General-in-Chief, with instructions to render any aid that may be in his power.
EDWIN M. STANTON, Secretary of War.
HARRISBURG, PA., October 23, 1862-3.20 p. m.
Honorable E. M. STANTON, Secretary of War:
Can I use General A. Porter, now here, to command troops to suppress the insurgents? I have no officer.
A. G. CURTIN, Governor of Pennsylvania.
WASHINGTON, October 23, 1862.
Governor CURTIN:
You are authorized to call upon General Porter, and he is instructed to report to you for orders. If you desire, I will give him the appointment of provost-marshal of the State.
EDWIN M. STANTON, Secretary of War.
WAR DEPARTMENT, Washington, October 23, 1862.
Major-General WOOL, Baltimore, Md.:
You will immediately repair to Harrisburg and consult with Governor Curtin upon the reported resistance to his draft. You will report if you have not troops enough in your department to enforce the laws.
H. W. HALLECK, General-in-Chief.
HEADQUARTERS, Baltimore, Md., October 23, 1862-11 p. m.
Major-General HALLECK:
I leave in the morning for Harrisburg. If troops should be required from Baltimore, I have only to say I have none to spare. This day I sent the One hundred and eighteenth New York Regiment, at the Relay House, to Washington. One of the men killed an engineer of the Washington train, and threats were made that other injuries might be done to passing trains. The man who murdered the engineer is in jail. I therefore deemed it best to send the regiment where it would do no harm.
JOHN E. WOOL, Major-General.
PENNSYLVANIA EXECUTIVE CHAMBER, Harrisburg, Pa., October 25, 1862.
Honorable E. M. STANTON, Secretary of War, Washington, D. C.:
SIR: The riots in Schuylkill County have ceased for the present. The object of the rioters seems to have been to prevent the draft, and to this end, I understand that they forcibly obstructed persons who had been drafted and were on their way to the place of rendezvous in conformity with the notice which had been served on them.
I beg the observe that this enrollment and draft have been made under the authority of and directly by the United States. I originally suggested, therefore, that they should be conducted by officers of the United States, but that suggestion not being adopted, I have acted for the United States in superintending the enrollment and the drawing of names for the quota. The next step contemplated by the regulations is the appointment of provost-marshals to enforce the attendance of the drafted men. I have not nominated persons to fill this office, because I do not perceive that officers of that kind are necessary.
By the act of 29th of June, 1861, penalties are provided for drafted men who shall not obey the orders of the President, but there is no act authorizing them to be forcibly impressed.
I would advise that a regulation be made directing that the courts-martial shall be immediately held on all recusants. These courts must be ordered by the President.
In this mode I think you would get the men more easily than by the use of force. Men unwilling to go, and unable to pay the probable fine, will serve in the army on pay [in preference] to being shut up in prison without pay. Those who are able to pay the fine will prefer using the money in procuring substitutes. The same limit of the fine will probably regulate the price of substitutes. I respectfully submit these matters for your consideration.
Very respectfully, yours, &c.,
A. G. CURTIN, [Governor of Pennsylvania.]
HARRISBURG, PA., October 27, 1862.
Honorable E. M. STANTON, Secretary of War:
I am happy to say that for the present the necessity for use of force in Schuylkill County is over. The decision and promptness, but more the presence of Bishop Wood, who kindly went up when requested, has relieved us all. I will retain the artillery a day or two, and keep our force organized for a day or two.
I am deeply indebted for your prompt and efficient support.
A. G. CURTIN.
HARRISBURG, October 27, [1862]-1.40 p.m.
(Received 2 p. m.)
ABRAHAM LINCOLN, President:
I feel it my duty to enter my protest against Orders, Numbers 154, as unjust to the people of the States, and calculated to demoralize and destroy volunteer organizations, not only because it is wrong in principle, but that in the manner in which it is being executed it must break the efficiency of the volunteer army now in the field in support of the Government. I very respectfully ask that it be revoked.
A. G. CURTIN.

Reactive programming is a general programming term that is focused on reacting to changes, such as data values or events. It is an event-based model where data is pushed to the consumer, as it becomes available.
RxJava is a Reactive Programming library for composing asynchronous and event-based programs by using observable sequences, coupled with some other features like functional programming, and easy concurrency makes RxJava a useful library. RxJava is an alternative to the more limited ways of doing asynchronous code in the JDK, in order to be more efficient with resources and increase an application's capacity to serve large number of clients, without the headache of writing low-level concurrent or and parallelized code
An observer subscribes to an Observable then that observer reacts to whatever item or sequence of items the Observable emits. This pattern facilitates concurrent operations because it does not need to block while waiting for the Observable to emit objects, but instead it creates a sentry in the form of an observer that stands ready to react appropriately at whatever future time the Observable does so.
{% highlight java %} Observable.create(observableEmitter -> { observableEmitter.onNext("Observable test"); }).subscribe(System.out::println); {% endhighlight %}Observable is intended for push (reactive) but can also be used for pull (interactive). It is lazy rather than eager. It can be used asynchronously or synchronously. It can represent 0, 1, many, or infinite values or events over time.
You can introduce multithreading into observable operators by instructing operators to operate on particular Schedulers.
{% highlight java %} Observable.create(observableEmitter -> { System.out.println(Thread.currentThread().getName()); observableEmitter.onNext("Observable test"); }).subscribeOn(Schedulers.newThread()).subscribe(System.out::println); {% endhighlight %}output : RxNewThreadScheduler-1 Observable test
Flowable implements the Reactive-Streams Pattern and offers factory methods, intermediate operators and the ability to consume reactive dataflows and operates with Publishers.
Backpressure is when in an Flowable processing pipeline, some asynchronous stages can't process the values fast enough and need a way to tell the upstream producer to slow down. Flowable takes backpressure into consideration, Observable does not.
The Flowable hosts the default buffer size of 128 elements for operators, accessible via bufferSize(), that can be overridden globally via the system parameter rx2.buffer-size. Most operators, however, have overloads that allow setting their internal buffer size explicitly.


THE DELICATE ART OF THE RIFLE A film review by Michael John Legeros Copyright 1997 Michael John Legeros
(CLC Films) Directed by D.W. Harper Written by Stephen Grant Cast David Grant, Stephen Grant, John Kessel MPAA Rating Not Rated Running Time 90 minutes Reviewed at The Rialto Theatre, Raleigh, NC (05APR97)
==
THE DELICATE ART OF THE RIFLE has been billed an "action adventure" by our local newspaper, "The News and Observer." I'd place the locally produced (and, so far, locally distributed) feature closer to comedy. Perhaps black comedy. Perhaps *absurdist* comedy, as there isn't much realism to this tale of a college theater tech (David Grant) who happens upon his roommate (Stephen Grant) shooting people from atop a campus building. The script is frequently funny, but the movie is long and, at times, tedious. (A brutal sound mix doesn't help matters much, either. Oof.) Filmed on or around my alma mater, North Carolina State Univer- sity. And, for when they become famous, the names to remember are Dante Harper (director), Stephen Grant (also writer), Todd Flinchum (producer), and Alicia Kratzer (production designer).

This package provides functions to compute pressure losses due to wall friction in a pipe. Every correlation is defined by a package that is derived by inheritance from the package WallFriction.PartialWallFriction. The details of the underlying pipe wall friction model are described in the UsersGuide. Basically, different variants of the equation
dp = λ(Re,D)*(L/D)*ρ*v*|v|/2
are used, where the friction loss factor λ is shown in the next figure:
| Name | Description |
|---|---|
| PartialWallFriction | Partial wall friction characteristic (base package of all wall friction characteristics) |
| NoFriction | No pipe wall friction, no static head |
| Laminar | Pipe wall friction for laminar flow in circular tubes (linear correlation) |
| QuadraticTurbulent | Pipe wall friction for turbulent flow in circular tubes (simple characteristic, mu not used) |
| LaminarAndQuadraticTurbulent | Pipe wall friction for laminar and turbulent flow in circular tubes (simple characteristic) |
| Detailed | Pipe wall friction for laminar and turbulent flow (detailed characteristic) |
| TestWallFrictionAndGravity | Pressure loss in pipe due to wall friction and gravity (only for test purposes; if needed use Pipes.StaticPipe instead) |


RUSH HOUR A film review by Steve Rhodes Copyright 1998 Steve Rhodes RATING (0 TO ****): **
RUSH HOUR, regardless of what you may have read, is NOT a Jackie Chan movie. Whereas it is true that Jackie Chan, one of the more engagingly delightful actors around, does appear in the movie, it is not the typical Chan project to showcase his comedic brand of martial arts skills.
Director Brett Ratner, director of the widely-panned MONEY TALKS, lacks much sense of action or comedic timing. RUSH HOUR drifts aimlessly for large portions, especially when Chan isn't in the frame. The script by Joel Cohen and Alec Sokolow has some good laughs, but it isn't written nearly smart enough and frequently feels the need to sink to bad racial humor. Besides making the cops asinine, a key plot twist revolves around whether to cut the red, green, or blue wire on the bomb. As always, the bomb squad, with a one chance in three of being right, will cut the right wire.
People who haven't seen the talented Chan in action may not be as disappointed as those who have become his fans. Non-fans will undoubtedly enjoy the few times Chan is allowed to cut loose, but those who have seen him at his best will likely be frustrated. Chan's charms come as much from his sweet cherubic demeanor as his athletic skills and daring stunts. RUSH HOUR features Chan as an untypically dour character whose seriousness gets in the way of his allure as an action hero with childlike innocence.
The movie's plot concerns the kidnapping of the Chinese consul's daughter in L.A. When Hong Kong sends their number one cop, Detective Inspector Lee (Jackie Chan), the FBI decides they don't want him messing with their case. The FBI agent in charge calls the L.A. Chief of Police to get a cop to baby-sit Lee and keep him out of trouble and out of their hair.
Philip Baker Hall and many other fine character actors are given nothing to do in the picture but collect a paycheck. (THE FULL MONTY's Tom Wilkinson sleepwalks his way through the movie as a criminal mastermind.) Hall plays the L. A. Chief of Police who sends the FBI the loudmouthed officer who has been driving him and everyone else crazy, Detective James Carter. Chris Tucker from MONEY TALKS plays the fast-mouthed Carter. Viewers' degree of tolerance for Tucker's brand of over-the-top, slapstick humor will be a major determinate of how much they like RUSH HOUR. At times he is extremely funny. In the best scenes, as when he and Jackie share dance and martial arts moves to the rock song "War," their chemistry clicks.
 The only completely successful part of the film is the series of outtakes shown during the closing credits. But any film where the outtakes are dramatically better than the "intakes" is clearly in trouble. If the director had thrown out the script, left the set, and just filmed the characters ad-libbing, he would have had a superior product.
RUSH HOUR runs 1:36. It is rated PG-13 for violence and profanity and would be fine for kids around ten and up.

Air from Siberia to send temperatures plunging from Texas to New England
by Associated Press- National Weather Service says 200 records could fall
- Snow expected into Veterans Day holiday
Air from Siberia heading towards a huge chunk of the US could set record low temperatures from Texas to New England between Monday and Wednesday.
National Weather Service meteorologist Kevin Donofrio said on Saturday the National Digital Forecast Database indicated that some 200 records might fall.
For example, the expected high on Tuesday of 23F (-5C) at Chicago’s O’Hare airport would be a full 5F (3C) lower than the record-low set in 1995.
The cold front was expected to move through the upper midwest and the northern plains on Sunday, then continue south and east on Monday and Tuesday, sending temperatures below freezing all the way south to the Gulf coast.
The front will bring January-like temperatures to some locations that are expected to be as much as 30F (17C) colder than normal for the time of year.
Donofrio said the leading edge of the system would bring some snow this weekend and on Monday, which is the Veterans Day holiday. Although the snow is expected to taper off on Monday, temperatures are forecast to keep falling.

Effective 1 July 2015, the I cent and 2 cent EC coins will be withdrawn from circulation. The coins will no longer be valid either as consumers will not be able to conduct transactions using these coins. Persons can present the coins at any of the commercial banks which operate within the Eastern Caribbean Currency Union (ECCU) to receive face value.
A price rounding system will be implemented within the ECCU countries for the settlement of cash transactions only, whereby the total payment, inclusive of duties, fees and taxes, will be rounded symmetrically to the nearest five cents. Non-cash payments using cheques, debit andcredit cards will not be impacted and therefore will not be rounded.
International dialing code for St Kitts Nevis is +1 869.
A prepaid St Kitts & Nevis SIM card with an international cell phone is the most convenient and economical solution. All incoming calls while you travel in St Kitts & Nevis are FREE, regardless of where they originate. Pay the local rate for local calls and use a cellular phone in St Kitts & Nevis.
Digicel update December 2014:
Anyone cruising using Digicel should be aware that if you purchase a SIM card in one country, it cannot be topped up in different one, as previously possible. So if you wish to use the sim bought here while cruising in other countries, you should either put on a large enough sum to cover your needs, or set up an account and do it online.

/-- Chinese Remainder Theorem. Atiyah-Macdonald 1.10, Eisenbud Ex.2.6, Stacks 10.14.4 (00DT) -/ theorem exists_sub_mem [fintype ι] {f : ι → ideal R} (hf : ∀ i j, i ≠ j → f i ⊔ f j = ⊤) (g : ι → R) : ∃ r : R, ∀ i, r - g i ∈ f i :=
Someone complained that this is not "actually" the Chinese Remainder Theorem
because the Chinese Remainder Theorem is a ring isomorphism
but I'd like to argue that this is actually how most people use Chinese Remainder Theorem
or at least this is the meat of the theorem
but I'm not sure if that's ok
Prove both.
I'm guessing the isomorphism is not that hard.
I think it's fine calling this the chinese remainder theorem in comments, it's not like that's unique
there's already another thing being called the CRT over the naturals
If anything, you should be liberal in calling things with famous names because that will make them easier to find
if I search for the chinese remainder theorem I should find any theorems that have a reasonable claim to the name
I would love searching for Chinese Remainder Theorem to produce at least 4 statements: about integers, about natural numbers, the "concrete" statement Kenny has proved, and the isomorphism of rings.
Of course there are several versions of this theorem. But why indicating references to books if you are proving a weaker statement than what's in books?
if the reference in the book is the weaker statement...
I looked at Atiyah-Macdonald 1.10 and I admit I don't see the resemblance
oh, I think this is one direction of 1.10(ii)
I would say something like "lemma for reverse direction of A-M 1.10(ii)" by way of reference. You should be precise if you want to reference an explicit theorem in the literature
Also we should start a bibliography. "Atiyah-Macdonald 1.10" is a little cavalier
I think this should be merged anyway (once the bibliography issue has been sorted out); the isomorphism can be done later, and this PR is complete on its own
I looked at Atiyah-Macdonald 1.10 and I admit I don't see the resemblance
@Mario Carneiro often the meat of the theorem is not tagged with a name, but the named theorem is often a simple corollary of a hard lemma
Sylow I:
"lemma": for each subgroup H < G of order p^i where i<n where |G| = p^n k, there is a subgroup of order p^(k+1)
"corollary": there is a subgroup of order p^n (proof: easy induction)
FTG:
"lemma": a lot of lemmas about normality and stuff, including a heavy proof of a very technical lemma that for any finite subgroup H of Aut(K) for some field K, K is galois over the fixed field K^H, of index |H|.
"theorem": fundamental theorem of galois theory (proof: easy application of the 10 lemmas above)
FTC:
"lemma": integration is linear (proof: partition refinement, etc)
"lemma": mean value theorem (proof: i don't even know)
"theorem": fundamental theorem of calculus (proof: easy application of linearity and mean value theorem)
This is true. If it makes you feel better you can call it a "main lemma"
@Kenny Lau I would not put any references to theorem numbers of the stacks project. They change very often. That is exactly what the tags were developed to solve. The tags are stable references.
So you're only proving the surjectivity of R -> prod R / I_i, however the kernel is obviously what it's supposed to be.
/-- Chinese Remainder Theorem. Atiyah-Macdonald 1.10, Eisenbud Ex.2.6, Stacks 00DT -/ noncomputable def quotient_inf_ring_equiv_pi_quotient [fintype ι] (f : ι → ideal R) (hf : ∀ i j, i ≠ j → f i ⊔ f j = ⊤) : (⨅ i, f i).quotient ≃r Π i, (f i).quotient := { hom := is_ring_hom_quotient_inf_to_pi_quotient f, .. equiv.of_bijective (bijective_quotient_inf_to_pi_quotient hf) }
Is this what Patrick wants? Surely this will stop his complaints
The references are still unclear. Not all of them say exactly this statement, for example A-M has 3 or 4 different statements in subparts of 1.10
what should I do?
for A-M
Eisenbud Ex.2.6 is fine
Stacks is a bit different
For A-M none of the statements are this exactly
so I should just keep Eisenbud?
You could either do the minor variations used in A-M and reference them, or drop the reference, or be more vague about it e.g. "similar to A-M 1.10"
You are allowed to put references on more than one theorem you know
how does it look now?
@Chris Hughes would you like to merge?

NAME
ssh-keysign - ssh helper program for host-based authenticationSYNOPSIS
DESCRIPTION
is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with SSH protocol version 2.is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign to ``yes''
is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authentication.
FILES
- /etc/ssh/ssh_config
- Controls whether is enabled.
- /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
- These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, readable only by root, and not accessible to others. Since they are readable only by root, must be set-uid root if host-based authentication is used.
ENVIRONMENT
- SSH_USE_STRONG_RNG
- The reseeding of the OpenSSL random generator is usually done from /dev/urandom If the SSH_USE_STRONG_RNG environment variable is set to value other than 0 the OpenSSL random generator is reseeded from /dev/random The number of bytes read is defined by the SSH_USE_STRONG_RNG value. Minimum is 6 bytes. This setting is not recommended on the computers without the hardware random generator because insufficient entropy causes the connection to be blocked until enough entropy is available.

Zac Posen Closes His Eponymous Label
by Nerisha PenroseZac Posen is shutting down business.
On Friday, November 1, to the surprise of literally everyone, WWD reported that Zac Posen, the designer who founded his namesake label in 2001, is officially shutting down his business. According to WWD, Posen explained that "we were in a sale process and we ran out of time" and his decision to shut down his label was "surprising and immediate." Posen said his biggest struggle was trying to "find the right strategic partners at this tough time in retail and in the industry."
The immediate closure means that all production and operations will cease immediately, including the designer's official website which has already been shut down and directs customers to a domain page. Posen's latest collection, which debuted in a September campaign starring model Winnie Harlow, will no longer be shipped.
Following the news, Posen took to the brand's Instagram to say his final goodbyes.
"I want to express my appreciation to our extraordinary team and for all those who have stood by me and the brand," Posen captioned a group photo of his Zac Posen staff.
"I owe a great deal of gratitude for their unwavering support for and dedication to the Company," he continued. "I am grateful to the team who lent their incomparable talent and commitment along the way. I remain incredibly proud of what we created and hopeful for the future. Love ZP."

Clemson vs. Wake Forest: Game Time, Spread, Channel, Announcers
by Tzvi MachlinThe Clemson Tigers look to extend their winning streak to 26 games as they take on the Wake Forest Demon Deacons in their final in-conference game of the year.
Clemson clinched a spot in the ACC Championship Game last week after beating NC State and watching Wake Forest lose to Virginia Tech. The Tigers seemed on the verge of losing after a rough September. But since then they’ve reeled off five wins where they’ve scored at least 45 points while allowing 14 or less.
If not for Wake Forest’s loss to Virginia Tech last week, this game would have had far greater implications. The Demon Deacons would have been in a position to steal a spot in the ACC Championship Game out from under Clemson if they had won out. But now, even if Wake Forest upsets the heavily-favored Tigers, they’ll have to settle for second place in the division.
Given that Clemson has outscored their last five foes by 31 to 52 points, it’s no shock that the Tigers are favored by five touchdowns at home.
Here are the details for the game:
Game Time: 3:30 PM ET
Channel: ABC
Spread: Clemson -34
Over/Under: 59.5
Announcers: Bob Wischusen, Dan Orlovsky, Allison Williams
With so many strong one-loss teams out there Clemson has no room for error if they want to make the College Football Playoff.
They’ll have a bye next week before their season finale against South Carolina.


Exercise 5: Use style inheritance to refactor repeated code
The goal of this exercise is to use Style Inheritance to avoid repeated Setters in Styles that target the same type of control.
To complete the exercise, you will need Visual Studio for Windows or macOS with the Xamarin development tools installed. You will also need either an emulator/simulator or a device to run the exercise on. Please see the setup page if you need help installing the Xamarin development environment.
Open the starter solution
This exercise is a continuation of the previous exercise. You can use your existing solution or begin from the prior Exercise 4 > Completed solution in your copy of the cloned or downloaded course materials.
Create a base style
Here you will define a new Style
with values that overlap with the Style
you wrote previously.
- Open StandardTipPage.xaml.
- Add a
Style
to the page's resource dictionary. Use aKey
of baseLabelStyle and aTargetType
of Label. - Add a
Setter
to your style that sets theFontSize
property to 22. Notice how thisSetter
also appears in your otherStyle
. - Apply the baseLabelStyle to the two labels on the page that display the output (i.e. that display the calculated amounts for the tip and the total). Remove the explicit
FontSize
settings from these labels. - Run the application on a platform of your choice. Verify that the UI looks the same as it did previously.
<ResourceDictionary>
…
<Style x:Key="baseLabelStyle" TargetType="Label">
<Setter Property="FontSize" Value="22" />
</Style>
</ResourceDictionary>
Use style inheritance
Here you will refactor your two Styles
into an inheritance hierarchy in order to eliminate the repeated Setter
.
- Open StandardTipPage.xaml.
- Locate the infoLabelStyle
Style
in the page's resource dictionary. Set theBasedOn
property of this style to your baseLabelStyle.
<Style x:Key="infoLabelStyle" BasedOn="{StaticResource baseLabelStyle}" TargetType="Label">
<Setter Property="FontAttributes" Value="Bold" />
<Setter Property="FontSize" Value="22" />
</Style>
- Remove the
Setter
forFontSize
from infoLabelStyle. It is no longer needed because thisStyle
now inherits theFontSize
setting from the base style. - Run the app and verify the UI looks the same.
<Style x:Key="infoLabelStyle" BasedOn="{StaticResource baseLabelStyle}" TargetType="Label">
<Setter Property="FontAttributes" Value="Bold" />
</Style>
Exercise summary
In this exercise, you used Style
inheritance to eliminate repeated code. Although this example was minimal, the benefits become even greater in complex cases where multiple setters can be removed.
You can view the completed solution in the Exercise 5 > Completed folder of your copy of the cloned or downloaded course materials.


For The past 1 year I have been working on Blockchain Technology and writing decentralized apps using floblockchain and ethereum I have more than 3 years of experience in the field of Web and Software Development. Specialized in blockchain and distributed ledger apps.
My objectives are increasing my knowledge in applied computer science and new technologies especially blockchain. Always looking forward to learn new technologies and accept tasks that are challenging.

Dot com bubble did burst, but after the crash, the world wide Web eventually rose from the ashes of the 1990s and became one of the most transformative technologies the world has ever known. Blockchain, it seems, has that same potential — it’s just in its the dot-com phase right now.
The growth of this industry is main caused by the demand of large businesses wishing to sell products and services to their customers and to automate business workflow. “Websites promote you 24/7: No employee will do that.”
coder’s high: those times when, for hours on end, zipping through the code. Hunger, thirst, sleepiness, and even pain all faded away while I was staring at the screen, thinking and typing, until I’d reach the point of exhaustion and it would come crashing down on me.
Many people believe that being a graphic designer is a free and quite laid back profession, which will enable you basically an unlimited amount of spare time. The truth is a whole different story.

This is a hangman-style word game in Node-js, using two different constructors.
The index.js runs the actual game with a dependency on the constructor, word.js.
word.js also has a dependency on the letter.js constructor.
When the game is run in node, the user is prompted to select level(Beginner, Medium, Hard) for the game or to exit the game.
In the beginner level, the user has 12 guesses to guess the word.
In the medium level, the user has 8 guesses to guess the word.
In the hard level, the user has only 4 guesses to guess the word.
Technologies Used
- JavaScript
- jQuery
- node.js
- Inquirer Npm


I think version control is benefitial for three main reasons. It allows multiple individuals to work on a file at the same time and later update that file by merging all of the changes to one master version of the file. Version control serves as a hisorical record of the file because it stores a version of the file everytime a change is made. It is because of this that we are able to restore previous versions of a file if needed. This is good because you can never really mess up a file and even if you do you can always go back to a previous version, restore it and continue working. Finally, version control is benefitial because when you save a change to a file you have to include a description of what the change was. This allows people working on the file days, weeks and even years from now a chance to understand the rational behind an integration.
Git helps keep track of changes because it is a version control system. Therefore it has all of the benefits mentioned above. Git allows users (one or many) to work seamlessly on a file at the same time. Git is really helpful in keeping track of changes because it is a complete record of all of the changes made to a file. You can look back at a file from its inception and see what was changed, who made the change and get an idea of why that change was made.
I have explained the benefits of git as a version control system above. If you are using git as your version control system you should use GitHub to store code because they work together. GitHub is a remote location that allows you to upload and store everything in one place online. GitHub also forsters collaboration because it allows your files to be accessed by many users. You can post your project on GitHub and by making it public other people can create and submit changes to be incorporated into the master document.
